The execution and delivery of this Agreement and the issuance, sale and delivery of the Shares have been duly authorized by all necessary corporate action.

2.7           The execution and delivery of this Agreement does not, and the consummation of the transactions contemplated hereby will not, conflict with, or result in any violation of, or default under (with or without notice or lapse of time, or both), or give rise to a right of termination, cancellation or acceleration of any obligation or to a loss of a material benefit under any provision of any mortgage, indenture, lease or other agreement or instrument, permit, concession, franchise, license, judgment, order, decree, statute, law, ordinance, rule or regulation applicable to the Company or its properties or assets. Neither the execution and delivery of this Agreement by the Company, nor the consummation of the transaction contemplated hereby, will result in the imposition of any security interest upon the Shares.

2.11         As of their respective dates, all reports and registration statements (the “SEC Reports”) filed or furnished by the Company with the SEC complied in all material respects with the requirements of the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the SEC promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the SEC with respect thereto as in effect at the time of filing and fairly present in all material respects the financial position of the Company as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments. To the knowledge of the Company, there are no material outstanding or unresolved comments in comment letters from the staff of the Division of Corporation Finance of the SEC with respect to any of the SEC Reports as of the date hereof.

公司提交或提供给证交会的所有报告和注册声明（合称“证交会报告”），每一次申报时，在所有重大方面均遵循证券法和美国1934年证券交易法及其修订案（“交易法”）以及证交会在 其中颁布的规则和规定的要求，并且在提交时，证交会报告中不存在对重大事实的不实陈述，也没有遗漏重大事实或必要的信息，进行误导。证交会报告中所包含的公司财务报表，在所有重大方面，均遵循所适用的会计规则要求和在提交时生效的证交会的规则和规定，并且真实反映该季度内公司的财务状况，经营状况和该季度结束时的现金流，但在未经审计的财务报表的情况下，应以正常年度结束时的调整数据为准。据公司所知，在任何证交会报告提交时，不存在对证交会公司金融部职员出具的评论信中重大的未决的评论。

2.12         The Company’s issued and outstanding ordinary shares are registered pursuant to Section 12(b) of the Exchange Act, and are listed for trading on the Nasdaq Capital Market under the symbol “CNEY.” There is no suit, action, proceeding or investigation pending or, to the knowledge of the Company, threatened against the Company by the Nasdaq Capital Market or the SEC with respect to any intention by such entity to deregister the ordinary shares or prohibit or terminate the listing of the ordinary shares on the Nasdaq Capital Market. The Company has taken no action that is designed to terminate the registration of the ordinary shares under the Exchange Act. Upon the issuance of the Shares, the Company’s issued and outstanding ordinary shares will continue to be registered pursuant to Section 12(b) of the Exchange Act and will be listed for trading on the Nasdaq Capital Market.

公司发行和流通的普通股按照证券法12（b）条进行登记，并且在纳斯达克资本市场上市交易，股票代码为“CNEY”。据公司所知，不存在任何未决的诉讼或调查会使纳斯达克资本市场或者证交会注销公司的普通股或禁止或终止公司普通股在纳斯达克上市。公司未采取交易法下的任何旨在终止普通股注册的行动。股票一经发行，公司发行和流通的普通股会持续按照交易法下12（b）条的规定注册，并且将会在纳斯达克资本市场上市交易。

The Purchaser understands that the Shares are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the Shares indefinitely unless they are registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Purchaser acknowledges that the Company has no obligation to register or qualify the Shares. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Shares, and on requirements relating to the Company that are outside of the Purchaser’s control, and which the Company is under no obligation and may not be able to satisfy.

受限制证券。认购人理解此股票目前没有，但将来可能会，依据证券法案进行注册，其原因是证券法案中的一条特定豁免条款。可依据此特定豁免条款取决于认购人在此协议表示的投资意愿的真实性和其陈述的准确性，以及其他因素。认购人理解此股票是适用的美国联邦和州证券法下的“受限制证券”，且根据这些法律，认购人必须无限期地持有股票直到此股票向美国证券交易委员会注册并得到州权力机关的认可，或相关的注册和审核要求中有豁免条款存在。认购人承认公司没有对股票进行注册或通过审核的义务。认购人进一步承认如果相关的注册和审核要求中有豁免条款存在，这些豁免条款将以多项要求为前提，包括但不限于，销售时间和方式、股票的持有期和与公司有关但不受认购人控制的要求，公司没有义务且可能无法满足这些要求。

3.10         No General Solicitation. The Purchaser is not purchasing the Shares as a result of any advertisement, article, notice or other communication regarding the Shares published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or general advertisement.

3.12         The Purchaser has been independently advised as to the restrictions with respect to trading the Shares and with respect to the resale restrictions imposed by applicable securities laws, confirms that no representation has been made to it by or on behalf of the Company with respect thereto, acknowledges the risks relating to an investment therein and of the fact that it may not be able to resell the Shares except in accordance with limited exemptions under applicable securities legislation and regulatory policy until expiry of the applicable restriction period and compliance with the other requirements of applicable law, or that the Shares are registered under the Securities Act and in compliance with the other requirements of applicable laws, that the Purchaser (or others for whom it is contracting hereunder) is solely responsible to find out what these restrictions are and the Purchaser is solely responsible (and neither the Company is not in any way responsible) for compliance with applicable resale restrictions and the Purchaser is aware that it may not be able to resell the Shares except in accordance with limited exemptions under applicable securities laws, or that the Shares are registered under the Securities Act, and it agrees that any certificates representing the Shares may bear a legend indicating that the resale of such securities is restricted;

3.13         The Company may complete additional financings, including project financing, in the future in order to develop the business of the Company and to fund its ongoing development; there is no assurance that such financings or project financings will be available and, if available, on reasonable terms; failure to obtain sufficient additional funds by way of debt or equity financings or through joint ventures will prevent the continued development of the business of the Company and any such future financings may have a dilutive effect on current security holders, including the Purchaser;

3.14      The Purchaser is solely responsible (and the Company is not responsible in any way) for compliance with all applicable hold periods and resale restrictions under which the Shares are subject;

认购人对遵守所有此股票受制于的适用的持有期和再销售限制独立负责（公司不以任何方式对此负责）。

3.15         The Purchaser understands that the purchase of the Shares is a highly speculative investment and that an investment in the Shares is suitable only for sophisticated investors and requires the financial ability and willingness to accept the possibility of the loss of all or substantially all of such investment as well as the risks and lack of liquidity inherent in an investment in the Company;

认购人理解购买此股票是具有很高投机性的投资，对此股票的投资只适合于复杂的投资者，且要求投资者具有接受失去全部或几乎全部投资、在本公司中投资的风险和流动性缺乏的经济能力和意愿。

3.16         Confidential Information. The Purchaser agrees that the Purchaser and its employees, agents and representatives will keep confidential and will not disclose, divulge or use (other than for purposes of monitoring its investment in the Company) any confidential information which the Purchaser may obtain from the Company pursuant to financial statements, reports and other materials submitted by the Company to the Purchaser pursuant to this Agreement, unless such information is (i) known to the public through no fault of the Purchaser or his or its employees or representatives; (ii) becomes part of the public domain other than by a breach of this Agreement; (iii) becomes known by the action of a third party not in breach of a duty of confidence; or (iv) is required to be disclosed to a third party pursuant to any applicable law, government resolution, or decision of any court or tribunal of competent jurisdiction; provided, however, that the Purchaser may disclose such information (i) to its attorneys, accountants and other professionals in connection with their representation of the Purchaser in connection with the Purchaser’s investment in the Company, (ii) to any prospective permitted transferee of the Securities, or (iii) to any general partner or affiliate of the Purchaser, so long as the prospective transferee agrees to be bound by the provisions of this Section.

保密信息。认购人同意认购人和其雇员、代理、代表将对从公司根据此协议提供的财务报表、报告和其他材料中得到的保密信息进行保密，且不会披露、泄露和使用这些信息（除非是为了跟踪其在公司中的投资），除非这些信息是：（i）在未因为认购人及其雇员过错的情况下为大众所知晓；（ii）在不是因违背此协定的情况下成为公共领域的一部分；（iii）在不是因为第三方违背保密责任进行的行为的情况下为人所知；或（iv）因第三方在适用管辖区的适用法律、政府决议、或法庭决定的要求下而被披露；但是，认购人可以（i）向其律师、会计师和其他和对本公司投资相关的专业人员，（ii）向任何可能的收到允许的此证券的交易方，或（iii）向认购人的一般合伙人或附属主体披露这些信息，只要可能的交易方同意受到本条款的限制。

3.17         Regulation S Exemption.  The Purchaser acknowledges and agrees that none of the Shares have been registered under the Securities Act, or under any state securities or "blue sky" laws of any state of the United States, and are being offered only in a transaction not involving any public offering within the meaning of the Securities Act, and, unless so registered, may not be offered or sold in the United States or to U.S. Persons (as defined herein), except pursuant to an effective registration statement under the Securities Act, or pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, and in each case only in accordance with applicable state and provincial securities laws. The Purchaser understands that the Shares are being offered and sold to him, her or it in reliance on an exemption from the registration requirements of United States federal and state securities laws under Regulation S promulgated under the Securities Act and that the Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of the Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of the Purchaser to acquire the Shares.  In this regard, the Purchaser represents, warrants and agrees that:

S 条例豁免条款。认购人确认且同意股票未根据证券法或美国任何州“蓝天”证券法注册，且仅在证券法定义中的非公众邀约交易中进行邀约，且，除非进行该等注册，不得在美国境内或向美国人士（见协议中定义）出售，但是根据证券法下有效注册声明的、或根据证券法中可用豁免的、或不受证券法注册规定的交易的，且在上述各种情况下均符合相关州证券法的情况除外。认购人理解，将要向其提供并出售的股票依赖于美国联邦和州证券法中S条例规定的注册要求的豁免。公司将依赖于认购人在协议里的陈述、保证、合意、确认和理解的真实性和准确性为上述用途与目的决定豁免条款在其中的适用性和认购人获得股票的适当性。就这点而言，认购人陈述，保证并同意：

(i)           The Purchaser is not a U.S. Person and is not an affiliate (as defined in Rule 501(b) under the Securities Act) of the Company and is not acquiring the Shares for the account or benefit of a U.S. Person.  A “U.S. Person” means any one of the following:

认购人非美国人士，也非公司的关联人士（根据证券法501（b）条款的定义），且认购人购买的股票不为美国人士的目的或利益。 “美国人士” 定义为下列中的任意一种：

任何在美国的自然人居民；

基于美国法律组织或设立的任何合伙企业、有限责任公司、公司或者其他实体；

以美国人士为执行人或管理人的任何财产；

受托人是美国人士的任何信托；

任何位于美国的外国机构的代理人或分支；

任何经纪人或其他受托人拥有的，为美国人士的利益所设的非全权买卖账户或类似账户（除财产或信托）；

任何经纪人或其他受托人设立、组成的或（如果是个人）居民拥有的全权买卖账户或类似账户（除了财产或信托）；

任何合伙企业，组织、公司或其他实体，如果其：

基于任何外国管辖地的法律设立或组成；和

由美国人士以证券法中投资未注册的证券为主要目的， 除非是由非自然人，财产或信托的实体的合资格投资者（根据证券法第501（a）条款）设立或组成或拥有 。

(ii)           At the time of the origination of contact concerning this Agreement and the date of the execution and delivery of this Agreement, the Purchaser was outside of the United States.

在此协议开始沟通和签署日和协议的交付日时，认购人在美国境外。

(iii)          The Purchaser realizes that the basis for the exemption may not be present if, notwithstanding such representations, the Purchaser has in mind merely acquiring the Shares for a fixed or determinable period in the future, or for a market rise, or for sale if the market does not rise. The Purchaser does not have any such intention.

认购人了解，尽管作出相关陈述，但如果认购人认购仅意图为在未来一定期间内持有股票、或为市场上涨、或为在市场未上涨的情况下出售，则豁免的依据可能不存在。认购人没有上述意图。

(iv)            The Purchaser will not, during the period commencing on the date of issuance of the Shares and ending six months after such date (the “Restricted Period”), offer, sell, pledge or otherwise transfer the Shares in the United States, or to a U.S. Person for the account or for the benefit of a U.S. Person, unless such Shares have been registered for resale pursuant to the Securities Act, or otherwise in a manner that is not in compliance with Regulation S.

认购人不会在自发行股票日到其后6个月期间内（“受限制期限”）内，在美国进行股票的邀约、出售、质押或另外转让，或为美国人士利益或目的向其转让（除非股票的转让已在 证券法下注册），或以任何其他不遵守S条例的方式进行邀约、出售、质押或另外转让。

(v)           The Purchaser will, after expiration of the Restricted Period, offer, sell, pledge or otherwise transfer the Shares only pursuant to registration under the Securities Act or an available exemption therefrom and, in accordance with all applicable state and foreign securities laws.

认购人将在受限制期限届满后，根据证券法中的注册规定或者适用豁免条款，并依照适用的州和外国证券法邀约、出售、质押或者转让股票。

(vi)           The Purchaser was not in the United States engaged in, and prior to the expiration of the Restricted Period will not engage in, any short selling of or any hedging transaction with respect to the Shares, including without limitation, any put, call or other option transaction, option writing or equity swap.

在受限制期限届满前，认购人未在美国参与任何股票的卖空或者任何关于股票的对冲交易，包括但不限于，任何看涨、看跌或其他期权交易，期权出售或股权互换。

(vii)           Neither the Purchaser nor or any person acting on his or her behalf has engaged, nor will engage, in any directed selling efforts to a U.S. Person with respect to the Shares and the Purchaser and any person acting on his or her behalf have complied and will comply with the “offering restrictions” requirements of Regulation S under the Securities Act.

认购人或任何作为其代表的人士不能已参与或将参与任何直接将股票出售给美国人士的行为，且认购人和任何作为其代表的人士已遵守并将遵守证券法中S 条例的“邀约限制”要求。

(viii)           The transactions contemplated by this Agreement have not been pre-arranged with a buyer located in the United States or with a U.S. Person, and are not part of a plan or scheme to evade the registration requirements of the Securities Act.

本协议计划的交易未与在美国境内的买家在或与美国人士预先安排，也非规避证券法注册要求计划或方案中的一部分。

(ix)           Neither the Purchaser nor any person acting on his or her behalf has undertaken or carried out any activity for the purpose of, or that could reasonably be expected to have the effect of, conditioning the market in the United States, its territories or possessions, for any of the Shares.  The Purchaser agrees not to cause any advertisement of the Shares to be published in any newspaper or periodical or posted in any public place and not to issue any circular relating to the Shares, except such advertisements that include the statements required by Regulation S under the Securities Act, and only offshore and not in the U.S. or its territories, and only in compliance with any local applicable securities laws.

认购人或任何作为其代表的人士未进行或采取对于股票可被合理预计影响美国的市场情况、其领地和财产的行为。认购人同意不使任何关于股票的广告出现在报纸或者期刊或者在任何公共场所张贴，不发行任何关于股票的通知，除非广告包含证券法S条例中的陈述，并且位于离岸且不在美国或其领土，并且要遵循任何当地可适用的证券法。

(x)           The Purchaser has carefully reviewed and completed the investor questionnaire annexed hereto as Exhibit A.

认购人已仔细审阅和完成 附录A中的投资人问卷调查.

3.18            No Advertisements or Direct Selling Effort.  The Purchaser is not subscribing for the Shares as a result of or subsequent to any advertisement, article, notice or other communication published in any newspaper, magazine, or similar media or broadcast over television or radio or via the Internet, or presented at any seminar or meeting. The Purchaser has not acquired the Shares as a result of, and will not itself engage in, any "directed selling efforts" (as defined in Regulation S) in the United States in respect of any of the Shares which would include any activities undertaken for the purpose of, or that could reasonably be expected to have the effect of, conditioning the market in the United States for the resale of any of the Shares; provided, however, that the Purchaser may sell or otherwise dispose of any of the Shares pursuant to registration of any of the Shares pursuant to the Securities Act and any applicable state securities laws or under an exemption from such registration requirements and as otherwise provided herein.

禁止广告或直接出售。认购人没有由于或继广告、文件、 通知或其他在任何报纸、杂志，或任何类似媒体或电视收音机转播或互联网或在任何研讨会或会议的其他出版传播之后认购股票。认购人收购股票并非基于，且其自身不参与，任何在美国境内关于股票“直接出售”（见S条例中定义），包括为股票转售而进行的可被合理预计影响美国的市场情况行为；但条件是，认购人可以通过证券法及相关州证券法下的股票注册或对于注册规定的豁免或本协议中另外所作规定对股票进行出售或另外处置。

3.19            Economic Considerations.  The Purchaser is not relying on the Company, or its affiliates or agents with respect to economic considerations involved in this investment.  The Purchaser has relied solely on his or her own advisors.

经济因素。认购人不能依赖于公司或其关联或代理关于此投资中包括的经济因素。认购人仅依赖于其顾问。

3.20            Compliance with Laws.  Any resale of the Shares during the “distribution compliance period” as defined in Rule 902(f) to Regulation S shall only be made in compliance with exemptions from registration afforded by Regulation S.  Further, any such sale of the Shares in any jurisdiction outside of the United States will be made in compliance with the securities laws of such jurisdiction.  The Purchaser will not offer to sell or sell the Shares in any jurisdiction unless the Purchaser obtains all required consents, if any.

遵守法律。任何根据S条例下902（f）条款在“发行合规期”内股票的转售必须仅在遵循S条例下注册豁免条款的情况进行。而且，任何此类在非美国管辖地的出售要遵循管辖地的法律。认购人不能在任何管辖地发出出售或者出售股票的邀约，除非认购人获得所有要求的同意（若有）。

4.1       Legends. Each certificate representing the Shares shall be endorsed with the following legends, in addition to any other legend required to be placed thereon by applicable federal or state securities laws:

标志。任何表现股票的证明应包含以下内容的标志背书，附加适用联邦或州证券法要求包含的标志：

“TRANSFER OF THESE SECURITIES IS PROHIBITED, EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF REGULATION S PROMULGATED UNDER THE SECURITIES ACT, PURSUANT TO REGISTRATION UNDER THE SECURITIES ACT, OR PURSUANT TO AVAILABLE EXEMPTION FROM REGISTRATION. HEDGING TRANSACTIONS MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE SECURITIES ACT.”

“除非符合证券法S条例、根据证券法注册规定，或根据可用的注册豁免， 不得转让该证券。除非符合证券法规定，不得进行对冲交易。”

4.2       Company’s Refusal to Register Transfer of Shares. The Company shall refuse to register any transfer of the Shares not made in accordance with (i) the provisions of Regulation S, (ii) pursuant to an effective registration statement filed under the Securities Act, or (iii) pursuant to an available exemption from the registration requirements of the Securities Act.
