Such Purchaser will not sell or otherwise dispose of the Shares without registration under the Securities Act, and under applicable state securities or “Blue Sky” laws, or pursuant to an exemption therefrom.

3.2.             Regulation S Representation:

有关S规则的声明

a)                   Such Purchaser is not a “U.S. Person” (as defined in Rule 902 of Regulation S under the Securities Act) and it understands that no action has been or will be taken in any jurisdiction by the Company that would permit a public offering of the securities in any country or jurisdiction where action for that purpose is required. It is not acquiring the Shares for the account or benefit of any U.S. persons except in accordance with exemption from registration requirements of the Securities Act or in a transaction not subject thereto. If such Purchaser is a natural person, he is a permanent resident of the People’s Republic of China (the “PRC”) and has been so at all times and has not maintained a residence in the United States for any purpose. If such Purchaser is an entity, it is incorporated, organized or formed under the laws of the PRC or a province of the PRC and has been so since its original incorporation, organization or formation, and it is not and has not acted by or through any agency or branch located in the United States.

上述认购者并非“美国人士”（“美国人士”一词具有《证券法》S规则第902条中所述含义），且上述认购者知悉公司方未在任何法域内采取任何可能使证券在任何国家或法域内获得公开发行的行动，而该行动为在上述国家或法域公开发行证券所需。上述认购者非为任何美国人士的账户或为其利益认购股份，豁免《证券法》中规定的登记要求的认购或非受上述法律管辖的交易除外。若上述认购者为自然人，其应自始即为中华人民共和国（“中国”）的永久居民，且未因任何原因曾在美国居住。若上述认购者为法人，其应在中国法或中国省级法规下设立、组织或成立，且自其最初设立、组织或成立之时起始终如此，并不曾经由位于美国的代理或分支机构进行活动。

b)                   Such Purchaser is not acquiring the Shares with a view to any distribution thereof that would violate the Securities Act or the securities laws of any state of the United States or any other applicable jurisdiction.

上述认购者认购标的股份，非为进行任何会违反《证券法》、美国各州或其他法域可适用的证券法律的对标的股份的分销。

c)                   Purchaser (A) agrees that it will not offer, sell or otherwise transfer any of the Shares nor, unless in compliance with the Securities Act, engage in hedging transactions involving such securities, on or prior to (x) the date one year after the later of the date of the Closing and the date of original issuance (or of any predecessor of any security proposed to be transferred by Purchaser) and (y) such later date, if any, as may be required by applicable law, except (a) to the Company, (b) pursuant to a registration statement that has been declared effective under the Securities Act, (c) for so long as any security is eligible for resale pursuant to Rule 144A under the Securities Act, to a person it reasonable believes is a “qualified institutional buyer” as defined in Rule 144A that purchases for its own account or for the account of another qualified institutional buyer to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales to persons who are not “U.S. Persons”(within the meaning of Regulation S), (e) pursuant to Rule 144 under the Securities Act, or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, and (B) agrees that it will give to each person to whom such security is transferred a notice substantially to the effect of this paragraph.

e)                   The Shares to be acquired by Purchaser will be acquired for investment for Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same. Such Purchaser does not presently have any contract, undertaking, agreement or arrangement with any person, directly or indirectly, to sell, transfer, distribute or grant participations to such person or to any third person, with respect to any of the Shares.

认购者仅为其自身投资目的认购标的股份，而非代持或代理，也非为转售或分配股份的任何部分。认购者目前并无出售、分配标的股份或向他人授予参与权的意图。上述认购者目前并未与他人签订向其或任何第三方就标的股份任何部分的出售、转让、分配或授予参与权的任何协议、承诺书、合同或协约。

3.3.                   Such Purchaser understands that he, she or it must bear the economic risk of the acquisition of the Shares made in connection herewith for an indefinite period of time because, among other reasons, the Shares have not been registered under the Securities Act or under the securities laws of certain states and, therefore, cannot be resold, pledged, assigned or otherwise disposed of unless they are subsequently registered under the Securities Act and under the applicable securities laws of such states or an exemption from such registration is available.

上述认购者知悉其需在不确定期间内承担认购本协议项下标的股份带来的经济风险，除其他原因外，由于标的股份未根据《证券法》或特定州的证券法进行登记，因此在后续未根据《证券法》以及适用的州证券法进行登记，或满足豁免上述登记的条件前无法转售、质押、让与或以其他方式处分。

3.4.                   Such Purchaser acknowledges and understands that no United States federal or state agency has passed upon the Shares or made any finding or determination as to the fairness of the terms of its investment.

上述认购者确知并知悉任何美国联邦或州政府机关均未就股份进行鉴定，也未就对标的股份进行投资的条款的公正性做出任何判定或裁决。

3.5.                   Such Purchaser has no need for liquidity with respect to the investment.

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “1933 ACT”), OR ANY STATE SECURITIES LAW. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF TANTECH HOLDINGS LTD (THE “COMPANY”) THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE COMPANY, (B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE 1933 ACT AND IN COMPLIANCE WITH ANY APPLICABLE LOCAL SECURITIES LAWS AND REGULATIONS, (C) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE 1933 ACT AND IN COMPLIANCE WITH ANY APPLICABLE LOCAL SECURITIES LAWS AND REGULATIONS, (D) IN COMPLIANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE 1933 ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAWS OR (E) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE 1933 ACT AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAWS, PROVIDED THAT, IN THE CASE OF (C), (D) OR (E), THE HOLDER HAS DELIVERED TO THE COMPANY AND THE REGISTRAR AND TRANSFER AGENT AN OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE COMPANY AND THE REGISTRAR AND TRANSFER AGENT TO SUCH EFFECT.

HEDGING TRANSACTIONS INVOLVING THE SECURITIES ARE PROHIBITED EXCEPT IN COMPLIANCE WITH THE 1933 ACT.”

“此股权证书中的证券尚未按照1933年美国证券法(“1933法案”)或任何州证券法的要求进行登记。为了保障 TANTECH HOLDINGS LTD (“公司”)的利益，持有人同意其购买的证券只可以在如下情况被邀约，出售，质押或转让：(a) 与公司之间的交易，(b) 根据有效的1933法案规定的申报登记表，并符合任何适用的当地证券法律和法规下进行的交易，(c) 1933法案第904条规定下符合任何适用的当地证券法律法规的美国境外交易，(d) 符合1933法案第144条规定的登记豁免，并符合任何适用的州证券法的交易, 或者 (e) 不需要按照1933法案的要求登记，并符合任何适用的州证券法的交易——前提是在(c)，(d)或(e)所述的情况下，持有人已向公司，公司注册处以及过户代理人交付了符合他们要求的有关公认地位的法律意见书。这些证券还受2021年5月【】日公司与投资者签订的股份认购协议第五节的限制。此外，除非符合1933法案的要求，此股权证书中的证券不可以被用来进行对冲交易。”
