and preferential transfers, and except that no representation is made herein regarding the enforceability of the Company’s

Authority. The Purchaser has the requisite power and authority to enter into and perform this Agreement and to purchase the Shares
being sold to it hereunder. The execution, delivery and performance of this Agreement by such Purchaser and the consummation by it of

company action, and no further consent or authorization of such Purchaser or its Board of Directors, stockholders, partners, members,
or managers, as the case may be, is required. This Agreement has been duly authorized, executed and delivered by such Purchaser and constitutes,
or shall constitute when executed and delivered, a valid and binding obligation of such Purchaser enforceable against such Purchaser in
accordance with the terms hereof.

 

    7

     

    

 

授权。认购人有签署和履行本协议以及购买依本协议向其销售的股票所需的权力和授权。认购人对本协议的签署、送达和履行和完成在此由所有必要的公司、合伙制企业或
 有限责任公司行为合法有效授权,不需要再由认购人或其董事会、股东会、合伙人、成员或经理进一步依情况同意或授权。本协议已被合法有效授权、签署和交付给认购人,并已构成或将在执行并交付后构成认购人有效和具有约束力的义务,可根据其条款对认购人执行。

 

3.3         
Purchase Entirely for Own Account. This Agreement is made with Purchaser in reliance upon Purchaser’s representation to the
Company, which by Purchaser’s execution of this Agreement, Purchaser hereby confirms that 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 that Purchaser has no present intention of selling, granting any participation in, or otherwise distributing
the same. By executing this Agreement, Purchaser further represents that Purchaser does not presently have any contract, undertaking,
agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect
to any of the Shares.

 

完全为本人购买。本协议是根据认购人对公司的陈述与认购人签订的。根据认购人对本协议的签署,认购人在此确认此股票是认购人为其本人而非作为代名人或代理人所购买,也非为了对其任何部分进行再销售或分销而购买,认购人目前没有意图对此股票进行销售、部分授权或分销。根据认购人对本协议的签署,认购人进一步确认认购人目前没有和任何人有合同、保证、协议或安排以向其或第三方销售、转让或准许参与投资此股票。

 

3.4

3.5         
Ability to Bear Risk. Purchaser understands and agrees that purchase of the Shares is a high-risk investment and Purchaser is able
to afford and bear an investment in a speculative venture having the risks and objectives of the Company, including a risk of total loss
of such investment. Purchaser must bear the substantial economic risks of the investment in the Shares indefinitely because none of the
Shares may be sold, hypothecated or otherwise disposed of unless subsequently registered under the Securities Act and applicable state
securities laws or an exemption from such registration(s) are available. The Purchaser represents that it is able to bear the economic
risk of an investment in the Shares and is able to afford a complete loss of such investment.

 

风险承担能力。认购人理解并同意对此股票的购买是具有高风险的投资,认购人有能力支付并承担在具有本公司风险和目标的投机性企业中的投资,包括该投资完全损失的风险。认购人必须无限期地承担在本股票中投资的相当的经济风险,因为除非之后本股票按照证券法案或州证券法进行注册或适用于这些注册相关的豁免条款存在,股票无法被销售、抵押或以其他形式处置。认购人表示有能力承担于此股票中的投资并有能力负担此投资的完全损失。

 

3.6          Disclosure
of Information. Purchaser has been given access to full and complete information regarding the Company and has utilized such
access to Purchaser’s satisfaction for the purpose of obtaining such information regarding the Company as Purchaser has
reasonably requested. In particular, Purchaser: (i) has received and thoroughly read and evaluated all the disclosures contained in
this Agreement; and (ii) has been given a reasonable opportunity to review such documents as Purchaser has requested and to ask
questions of, and to receive answers from, representatives of the Company concerning the terms and conditions of the Shares and the
business and affairs of the Company and to obtain any additional information concerning the Company’s business to the extent
reasonably available so as to understand more fully the nature of this investment and to verify the accuracy of the information
supplied. The Purchaser is satisfied that it has received adequate information with respect to all matters which he/she/it considers
material to its decision to make this investment.

 

    8

3.9           Restricted
Securities. Purchaser understands that the Shares have not been, although they may be, registered under the Securities Act, by reason
of a specific exemption from the registration provisions of the Securities Act, which depends upon, among other things, the bona fide
nature of the investment intent and the accuracy of Purchaser’s representations as expressed herein. Purchaser understands that
the Shares are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these
laws, 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. Except as otherwise provided herein and in accordance with the Registration
Rights Agreement, Purchaser acknowledges that the Company has no obligation to register or qualify the Shares. Purchaser further acknowledges

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 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。除非此协议中另有说明并且遵照注册权协议,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。

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

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

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。

(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.

 

    14

     

    

 

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.

 

3.19         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。

 

3.20         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。

 

    15

     

    

 

3.21         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)。

 

3.22         No
Minimum. The Purchaser understands that although there may be multiple Closing with other Purchasers, there might be no other Purchasers
and that the funds that the Company receives from the undersigned Purchaser in connection with this Agreement might be the only funds
that the Company receives from this placement. Such funds might not be sufficient to meet the Company’s funding needs in connection
with the placement.没有最低要求。认购人理解,虽然公司或许跟其他认购人有多次交割,但也可能不存在其他认购人,公司从本协议签字的认购人处收到的资金或许是公司在此次募集收到的唯一资金。这笔资金或许不足以满足公司与本次募集有关的募资需求。

5.11         Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to
be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall
remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by
such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would
have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared
invalid, illegal, void or unenforceable.

 

可分割性。如本协议的任何条款、规定、契约或限制被任何拥有司法管辖权的法院裁定为无效、非法、或不可执行,本协议的其他条款、规定、契约或限制将保持完全有效,并不因此在任何方式上受到影响、损坏或作废。协议双方应尽其商业上合理的努力找到并实施替代方式,以取得拟根据被裁定的条款、规定、契约或限制达到的相同或大部分相同的结果。

 

5.12         Remedies.
In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, the Purchaser
and the Company will be entitled to specific performance under this Agreement. The parties agree that monetary damages may not be adequate

5.14         Further
Assurances: Each party hereto shall from time to time at the request of the other party hereto do such further acts and execute
and deliver such further instruments, deeds and documents as shall be reasonably required in order to fully perform and carry out

5.15         Waivers.
No waiver by any party of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be
a continuing waiver in the future or a waiver of any other provisions, condition or requirement hereof and thereof, nor shall any delay
or omission of any party to exercise any right hereunder and thereunder in any manner impair the exercise of any such right accruing
to it thereafter.

5.16         Successors and Assigns. This Agreement may not be assigned by a party hereto without the prior written consent of the Company or
the Purchaser, as applicable, provided, however, that, subject to federal and state securities laws and as otherwise provided
in this Agreement, the Purchaser may assign its rights and delegate its duties hereunder in whole or in part (i) to a third party acquiring
all or substantially all of its Shares in a private transaction or (ii) to an affiliate, in each case, without the prior written consent
of the Company or the other purchasers participated in this Offering, after notice duly given by such Purchaser to the Company provided,
that no such assignment or obligation shall affect the obligations of such Purchaser hereunder and that such assignee agrees in writing
to be bound, with respect to the transferred securities, by the provisions hereof that apply to the Purchaser. The provisions of this
Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties. Nothing in
this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors
and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this

2.        Registration.

 

(a)              
On or prior to the Filing Date for the Initial Registration Statement, the Company shall prepare and file with the Commission
a Registration Statement covering the resale of all of the Registrable Securities for an offering to be made on a continuous basis pursuant
to Rule 415. In the event that, at any time, all of the Registrable Securities are no longer registered for resale under the Initial
Registration Statement or under an Additional Registration Statement, all Registrable Securities that are not then registered under an
effective Registration Statement shall be registered under an Additional Registration Statement, each such Additional Registration Statement,
which shall be filed on or before the applicable Filing Date for such Additional Registration Statement.

 

(b)              
Each Registration Statement filed hereunder shall be on Form F-3 (except if the Company is not then eligible to register for resale
the Registrable Securities on Form F-3, in which case such Registration Statement shall be on Form F-1 or on another appropriate form
in accordance herewith, subject to the provisions of Section 2(f)) and shall contain (unless otherwise directed by at least 85% in interest
of the Holders) substantially the “Plan of Distribution” attached hereto as Annex A and substantially the “Selling
Shareholder” section attached hereto as Annex B; provided, however, that no Holder shall be required to
be named as an “underwriter” without such Holder’s express prior written consent. Subject to the terms of this Agreement,
the Company shall use its commercially reasonable efforts to cause a Registration Statement filed under this Agreement (including, without
limitation, under Section 3(c)) to be declared effective under the Securities Act as promptly as possible after the filing thereof, but
in any event no later than the applicable Effectiveness Date, and shall use its commercially reasonable efforts to keep such Registration
Statement continuously effective under the Securities Act until the date that all Registrable Securities covered by such Registration
Statement continue to be Registrable Securities (the “Effectiveness Period”). The Company shall on the Trading Day
after the effective date of such Registration Statement, file a final Prospectus with the Commission as required by Rule 424. Failure
to file a final Prospectus as foresaid shall be deemed an Event under Section 2(e).

 

(c)              
Notwithstanding the registration obligations set forth in Section 2(a), if the Commission informs the Company that all of the
Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single
registration statement, the Company agrees to promptly inform each of the Holders thereof and use its commercially reasonable efforts
to file amendments to the Initial Registration Statement as required by the Commission, covering the maximum number of Registrable Securities
permitted to be registered by the Commission, on Form F-3 or such other form available to register for resale the Registrable Securities
as a secondary offering, subject to the provisions of Section 2(f); with respect to filing on Form F-3 or other appropriate form, and
subject to the provisions of Section 2(e) with respect to the payment of liquidated damages; provided, however, that prior
to filing such amendment, the Company shall use its commercially reasonable efforts to advocate with the Commission for the registration
of all of the Registrable Securities in accordance with the SEC Guidance, including without limitation, Compliance and Disclosure Interpretation
612.09.

 

    4

     

    

 

(d)              
Notwithstanding any other provision of this Agreement and subject to the payment of liquidated damages pursuant to Section 2(e),
if the Commission or any SEC Guidance sets forth a limitation on the number of Registrable Securities permitted to be registered on a
particular Registration Statement as a secondary offering (and notwithstanding that the Company used its commercially reasonable efforts
to advocate with the Commission for the registration of all or a greater portion of Registrable Securities), unless otherwise directed
in writing by a Holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration Statement
will be reduced as follows: 

 

		a.	First,
                                            the Company shall reduce or eliminate any securities to be included other than Registrable
                                            Securities; and

 

		b.	Second,
                                            the Company shall reduce Registrable Securities represented by Shares (applied, in the case
                                            that some Shares may be registered, to the Holders on a pro rata basis based on the total
                                            number of unregistered Shares held by such Holders). 

 

In
the event of a cutback hereunder, the Company shall give the Holder at least two (2) Trading Days prior written notice along with the
calculations as to such Holder’s allotment. In the event the Company amends the Initial Registration Statement in accordance with
the foregoing, the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission
or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form F-3 or
such other form available to register for resale those Registrable Securities that were not registered for resale on the Initial Registration
Statement, as amended.

 

    5

     

    

 

(e)              
If: (i) the Initial Registration Statement is not filed on or prior to its Filing Date (if the Company files the Initial Registration
Statement without affording the Holders the opportunity to review and comment on the same as required by Section 3(a) herein, the Company
shall be deemed to have not satisfied this clause (i)), or (ii) the Company fails to file with the Commission a request for acceleration
of a Registration Statement in accordance with Rule 461 promulgated by the Commission pursuant to the Securities Act, within five Trading
Days of the date that the Company is notified (orally or in writing, whichever is earlier) by the Commission that such Registration Statement
will not be “reviewed” or will not be subject to further review, or (iii) prior to the effective date of a Registration Statement,
the Company fails to file a pre-effective amendment and otherwise respond in writing to comments made by the Commission in respect of
such Registration Statement within fifteen (15) calendar days after the receipt of comments by or notice from the Commission that such
amendment is required in order for such Registration Statement to be declared effective, or (iv) a Registration Statement registering
for resale all of the Registrable Securities is not declared effective by the Commission by the Effectiveness Date of the Initial Registration
Statement, or (v) after the effective date of a Registration Statement, such Registration Statement ceases for any reason to remain continuously
effective as to all Registrable Securities included in such Registration Statement, or the Holders are otherwise not permitted to utilize,
for reasons outside of the Holders’ control, the Prospectus therein to resell such Registrable Securities, for more than fifteen
(15) consecutive calendar days or more than an aggregate of twenty-five (25) calendar days (which need not be consecutive calendar days)
during any 12-month period (any such failure or breach being referred to as an “Event”, and for purposes of clauses
(i) and (iv), the date on which such Event occurs, and for purpose of clause (ii) the date on which such five (5) Trading Day period
is exceeded, and for purpose of clause (iii) the date which such ten (10) calendar day period is exceeded, and for purpose of clause
(v) the date on which such fifteen (15) or twenty-five (25) calendar day period, as applicable, is exceeded being referred to as “Event
Date”), then, in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event Date
and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable
Event is cured, the Company shall pay to each Holder an amount in cash, as partial liquidated damages and not as a penalty, equal to
the product of 2.0% multiplied by the aggregate Subscription Amount paid by such Holder pursuant to the Subscription Agreement. If the
Company fails to pay any partial liquidated damages pursuant to this Section in full within seven days after the date payable, the Company
will pay interest thereon at a rate of 18% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to
the Holder, accruing daily from the date such partial liquidated damages are due until such amounts, plus all such interest thereon,
are paid in full. The partial liquidated damages pursuant to the terms hereof shall apply on a daily pro rata basis for any portion of
a month prior to the cure of an Event.

 

(f)               
If Form F-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall (i) register
the resale of the Registrable Securities on Form F-1 or another appropriate form and (ii) undertake to register the Registrable Securities
on Form F-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration Statement
then in effect until such time as a Registration Statement on Form F-3 covering the Registrable Securities has been declared effective
by the Commission.

 

(g)              
Notwithstanding anything to the contrary contained herein, in no event shall the Company be permitted to name any Holder or affiliate
of a Holder as an underwriter without the prior written consent of such Holder.

3.        Registration
Procedures.

 

In connection with the Company’s
registration obligations hereunder, the Company shall:

 

(a)              
Not less than three (3) Trading Days prior to the filing of each Registration Statement and not less than one (1) Trading Day
prior to the filing of any related Prospectus or any amendment or supplement thereto (including any document that would be incorporated
or deemed to be incorporated therein by reference), the Company shall (i) furnish to each Holder copies of all such documents proposed
to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject to the review
of such Holders, and (ii) cause its officers and directors, counsel and independent registered public accountants to respond to such
inquiries as shall be necessary, in the reasonable opinion of respective counsel to each Holder, to conduct a reasonable investigation
within the meaning of the Securities Act. The Company shall not file a Registration Statement or any such Prospectus or any amendments
or supplements thereto to which the Holders of a majority of the Registrable Securities shall reasonably object in good faith, provided
that, the Company is notified of such objection in writing no later than three (3) Trading Days after the Holders have been so furnished
copies of a Registration Statement or one (1) Trading Day after the Holders have been so furnished copies of any related Prospectus or
amendments or supplements thereto. Each Holder agrees to furnish to the Company a completed questionnaire in the form attached to this
Agreement as Annex B (a “Selling Shareholder Questionnaire”) on a date that is not less than two (2) Trading
Days prior to the Filing Date or by the end of the fourth (4th) Trading Day following the date on which such Holder receives
draft materials in accordance with this Section.

 

(b)              
(i) Prepare and file with the Commission such amendments, including post-effective amendments, to a Registration Statement and
the Prospectus used in connection therewith as may be necessary to keep a Registration Statement continuously effective as to the applicable
Registrable Securities for the Effectiveness Period and prepare and file with the Commission such additional Registration Statements
in order to register for resale under the Securities Act all of the Registrable Securities, (ii) cause the related Prospectus to be amended
or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and, as so supplemented or amended, to
be filed pursuant to Rule 424, (iii) respond as promptly as reasonably possible to any comments received from the Commission with respect
to a Registration Statement or any amendment thereto and provide as promptly as reasonably possible to the Holders true and complete
copies of all correspondence from and to the Commission relating to a Registration Statement (provided that, the Company shall excise
any information contained therein which would constitute material non-public information regarding the Company or any of its Subsidiaries),
and (iv) comply in all material respects with the applicable provisions of the Securities Act and the Exchange Act with respect to the
disposition of all Registrable Securities covered by a Registration Statement during the applicable period in accordance (subject to
the terms of this Agreement) with the intended methods of disposition by the Holders thereof set forth in such Registration Statement
as so amended or in such Prospectus as so supplemented.

 

    7

     

    

 

(c)              
If during the Effectiveness Period, the number of Registrable Securities at any time exceeds 100% of the number of Ordinary Shares
then registered in a Registration Statement, then the Company shall file as soon as reasonably practicable, but in any case prior to
the applicable Filing Date, an additional Registration Statement covering the resale by the Holders of not less than the number of such
Registrable Securities.

 

(d)              
Notify the Holders of Registrable Securities to be sold (which notice shall, pursuant to clauses (iii) through (vi) hereof, be
accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as reasonably
possible (and, in the case of (i)(A) below, not less than one (1) Trading Day prior to such filing) and (if requested by any such Person)
confirm such notice in writing no later than one (1) Trading Day following the day (i)(A) when a Prospectus or any Prospectus supplement
or post-effective amendment to a Registration Statement is proposed to be filed, (B) when the Commission notifies the Company whether
there will be a “review” of such Registration Statement and whenever the Commission comments in writing on such Registration
Statement, and (C) with respect to a Registration Statement or any post-effective amendment, when the same has become effective, (ii)
of any request by the Commission or any other federal or state governmental authority for amendments or supplements to a Registration
Statement or Prospectus or for additional information, (iii) of the issuance by the Commission or any other federal or state governmental
authority of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities
or the initiation of any Proceedings for that purpose, (iv) of the receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation
or threatening of any Proceeding for such purpose, (v) of the occurrence of any event or passage of time that makes the financial statements
included in a Registration Statement ineligible for inclusion therein or any statement made in a Registration Statement or Prospectus
or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions
to a Registration Statement, Prospectus or other documents so that, in the case of a Registration Statement or the Prospectus, as the
case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (vi) of the
occurrence or existence of any pending corporate development with respect to the Company that the Company believes may be material and
that, in the determination of the Company, makes it not in the best interest of the Company to allow continued availability of a Registration
Statement or Prospectus; provided, however, that in no event shall any such notice contain any information which would
constitute material, non-public information regarding the Company or any of its Subsidiaries.

 

    8

     

    

 

(e)              
Use its commercially reasonable efforts to avoid the issuance of, or, if issued, to obtain the withdrawal of (i) any order stopping
or suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification)
of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.

 

(f)               
Furnish to each Holder, without charge, at least one conformed copy of each such Registration Statement and each amendment thereto,
including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference to the extent
requested by such Person, and all exhibits to the extent requested by such Person (including those previously furnished or incorporated
by reference) promptly after the filing of such documents with the Commission; provided, that any such item which is available on the
EDGAR system (or successor thereto) need not be furnished in physical form.

 

(g)              
Subject to the terms of this Agreement, the Company hereby consents to the use of such Prospectus and each amendment or supplement
thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus
and any amendment or supplement thereto, except after the giving of any notice pursuant to Section 3(d).

 

(h)              
Prior to any resale of Registrable Securities by a Holder, use its commercially reasonable efforts to register or qualify or cooperate
with the selling Holders in connection with the registration or qualification (or exemption from the Registration or qualification) of
such Registrable Securities for the resale by the Holder under the securities or Blue Sky laws of such jurisdictions within the United
States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption therefrom) effective during
the Effectiveness Period and to do any and all other acts or things reasonably necessary to enable the disposition in such jurisdictions
of the Registrable Securities covered by each Registration Statement, provided that the Company shall not be required to qualify generally
to do business in any jurisdiction where it is not then so qualified, subject the Company to any material tax in any such jurisdiction
where it is not then so subject or file a general consent to service of process in any such jurisdiction.

 

    9

     

    

 

(i)                
If requested by a Holder, cooperate with such Holder to facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the
extent permitted by the Subscription Agreement, of all restrictive legends, and to enable such Registrable Securities to be in such denominations
and registered in such names as any such Holder may request.

 

(j)                
Upon the occurrence of any event contemplated by Section 3(d), as promptly as reasonably possible under the circumstances taking
into account the Company’s good faith assessment of any adverse consequences to the Company and its shareholders of the premature
disclosure of such event, prepare a supplement or amendment, including a post-effective amendment, to a Registration Statement or a supplement
to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required
document so that, as thereafter delivered, neither a Registration Statement nor such Prospectus will contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading. If the Company notifies the
Holders in accordance with clauses (iii) through (vi) of Section 3(d) above to suspend the use of any Prospectus until the requisite
changes to such Prospectus have been made, then the Holders shall suspend use of such Prospectus. The Company will use its commercially
reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company shall be entitled
to exercise its right under this Section 3(j) to suspend the availability of a Registration Statement and Prospectus, subject to the
payment of partial liquidated damages otherwise required pursuant to Section 2(e), for a period not to exceed 60 calendar days (which
need not be consecutive days) in any 12-month period.

 

(k)              
Otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the Commission under the
Securities Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final Prospectus, including
any supplement or amendment thereof, with the Commission pursuant to Rule 424 under the Securities Act, promptly inform the Holders in
writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified in Rule 172 and, as a
result thereof, the Holders are required to deliver a Prospectus in connection with any disposition of Registrable Securities and take
such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder.

 

(l)                
The Company shall use its commercially reasonable efforts to maintain eligibility for use of Form F-3 (or any successor form thereto)
for the registration of the resale of Registrable Securities.

 

    10

     

    

 

(m)            
The Company may require each selling Holder to furnish to the Company a certified statement as to the number of Ordinary Shares
beneficially owned by such Holder and, if required by the Commission, the natural persons thereof that have voting and dispositive control
over the shares. During any periods that the Company is unable to meet its obligations hereunder with respect to the registration of
the Registrable Securities solely because any Holder fails to furnish such information within three Trading Days of the Company’s
request, any liquidated damages that are accruing at such time as to such Holder only shall be tolled and any Event that may otherwise
occur solely because of such delay shall be suspended as to such Holder only, until such information is delivered to the Company.

 

4.        Registration
Expenses. All fees and expenses incident to the performance of or compliance with, this Agreement by the Company shall be borne by
the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and expenses referred to
in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees
and expenses of the Company’s counsel and independent registered public accountants) (A) with respect to filings made with the
Commission, (B) with respect to filings required to be made with any Trading Market on which the ordinary share is then listed for trading,
and (C) in compliance with applicable state securities or Blue Sky laws reasonably agreed to by the Company in writing (including, without
limitation, fees and disbursements of counsel for the Company in connection with Blue Sky qualifications or exemptions of the Registrable
Securities), (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities), (iii)
messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Company, (v) Securities Act liability insurance,
if the Company so desires such insurance, and (vi) fees and expenses of all other Persons retained by the Company in connection with
the consummation of the transactions contemplated by this Agreement. In addition, the Company shall be responsible for all of its internal
expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including, without limitation,
all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit and the
fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange as required hereunder.
In no event shall the Company be responsible for any broker or similar commissions of any Holder or any legal fees or other costs of
the Holders.

 

    11

     

    

 

5.        Indemnification.

 

(a)              
Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold
harmless each Holder, the officers, directors, members, partners, agents, brokers (including brokers who offer and sell Registrable Securities
as principal as a result of a pledge or any failure to perform under a margin call of Ordinary Shares), investment advisors and employees
of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act) and the officers, directors, members, shareholders, partners, agents and employees (of each such controlling Person, to
the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including,
without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, relating
to a third-party claim arising out of (1) any untrue statement of a material fact contained in a Registration Statement, any Prospectus
or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to
any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the
case of any Prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading or (2) any violation
by the Company of the Securities Act, the Exchange Act or any state securities law, or any rule or regulation thereunder, in connection
with the performance of its obligations under this Agreement, except to the extent, but only to the extent, that (i) such untrue statements
or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder expressly for
use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of
Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in a Registration Statement,
such Prospectus or in any amendment or supplement thereto (it being understood that the Holder has approved Annex A hereto for this purpose)
or (ii) in the case of an occurrence of an event of the type specified in Section 3(d)(iii)-(vi), the use by such Holder of an outdated,
defective or otherwise unavailable Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated,
defective or otherwise unavailable for use by such Holder and prior to the receipt by such Holder of the Advice contemplated in Section
6(b). The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding arising from or in connection
with the transactions contemplated by this Agreement of which the Company is aware. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such indemnified person and shall survive the transfer of any Registrable Securities
by any of the Holders in accordance with Section 6(f).

(b)              
Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its
directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent
permitted by applicable law, from and against all Losses, as incurred, to the extent arising out of or based solely upon: any untrue
or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus, or in any amendment or supplement
thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required
to be stated therein or necessary to make the statements therein (in the case of any Prospectus or supplement thereto, in light of the
circumstances under which they were made) not misleading (i) to the extent, but only to the extent, that such untrue statement or omission
is contained in any information so furnished in writing by such Holder to the Company expressly for inclusion in such Registration Statement
or such Prospectus or (ii) to the extent, but only to the extent, that such information relates to such Holder’s information provided
in the Selling Shareholder Questionnaire or the proposed method of distribution of Registrable Securities and was reviewed and expressly
approved in writing by such Holder expressly for use in a Registration Statement (it being understood that the Holder has approved Annex
A hereto for this purpose), such Prospectus or in any amendment or supplement thereto. In no event shall the liability of a selling Holder
be greater in amount than the dollar amount of the proceeds received by such Holder upon the sale of the Registrable Securities included
in the Registration Statement giving rise to such indemnification obligation.

 

(c)              
Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity
hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is
sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to assume the defense
thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses
incurred in connection with defense thereof, provided that the failure of any Indemnified Party to give such notice shall not relieve
the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be
finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure
shall have materially and adversely prejudiced the Indemnifying Party.

 

An Indemnified
Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed
in writing to pay such fees and expenses, (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding
and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding, or (3) the named parties to any such
Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and counsel to the Indemnified
Party shall reasonably believe that a material conflict of interest is likely to exist if the same counsel were to represent such Indemnified
Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects
to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense
thereof and the reasonable fees and expenses of no more than one separate counsel shall be at the expense of the Indemnifying Party).
The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent
shall not be unreasonably withheld or delayed. No Indemnifying Party shall, without the prior written consent of the Indemnified Party,
effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes
an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

 

    13

     

    

 

Subject to the
terms of this Agreement, all reasonable fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent
incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall
be paid to the Indemnified Party, as incurred, within ten Trading Days of written notice thereof to the Indemnifying Party, provided
that the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and expenses applicable to such
actions for which such Indemnified Party is finally determined by a court of competent jurisdiction (which determination is not subject
to appeal or further review) not to be entitled to indemnification hereunder.

 

(d)              
Contribution. If the indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party or insufficient
to hold an Indemnified Party harmless for any Losses, then each Indemnifying Party shall contribute to the amount paid or payable by
such Indemnified Party, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified
Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether
any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material
fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount
paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in this Agreement,
any reasonable attorneys’ or other fees or expenses incurred by such party in connection with any Proceeding to the extent such
party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such
party in accordance with its terms.

 

The parties hereto
agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or
by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding
paragraph. In no event shall the contribution obligation of a Holder of Registrable Securities be greater in amount than the dollar amount
of the proceeds (net of all expenses paid by such Holder in connection with any claim relating to this Section 5 and the amount of any
damages such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission)
received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.

 

    14

     

    

 

The indemnity and
contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified
Parties.

 

6.        Miscellaneous.

 

(a)              
Remedies. In the event of a breach by the Company or by a Holder of any of their respective obligations under this Agreement,
each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement,
including recovery of damages, shall be entitled to specific performance of its rights under this Agreement. Each of the Company and
each Holder agrees that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it
of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance in respect
of such breach, it shall not assert or shall waive the defense that a remedy at law would be adequate.

 

(b)              
Discontinued Disposition. By its acquisition of Registrable Securities, each Holder agrees that, upon receipt of a notice
from the Company of the occurrence of any event of the kind described in Section 3(d)(iii) through (vi), such Holder will forthwith discontinue
disposition of such Registrable Securities under a Registration Statement until it is advised in writing (the “Advice”)
by the Company that the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed. The Company will
use its commercially reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company
agrees and acknowledges that any periods during which the Holder is required to discontinue the disposition of the Registrable Securities
hereunder shall be subject to the provisions of Section 2(e).

 

(c)              
Piggy-Back Registrations. If, at any time during the Effectiveness Period, there is not an effective Registration Statement
covering all of the Registrable Securities and the Company shall determine to prepare and file with the Commission a registration statement
relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other
than on Form F-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to
be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with the Company’s
stock option or other employee benefit plans, then the Company shall deliver to each Holder a written notice of such determination and,
if within fifteen days after the date of the delivery of such notice, any such Holder shall so request in writing, the Company shall
include in such registration statement all or any part of such Registrable Securities such Holder requests to be registered; provided,
however, that the Company shall not be required to register any Registrable Securities pursuant to this Section 6(c) that are
eligible for resale pursuant to Rule 144 (without volume restrictions or current public information requirements) promulgated by the
Commission pursuant to the Securities Act or that are the subject of a then effective Registration Statement that is available for resales
or other dispositions by such Holder.

 

    15

     

    

 

(d)              
Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be
in writing and signed by the Company and the Holders of 50.1% or more of the then outstanding Registrable Securities (for purposes of
clarification, this includes any Registrable Securities issuable upon exercise or conversion of any Security, if applicable), provided
that, if any amendment, modification or waiver disproportionately and adversely impacts a Holder (or group of Holders), the consent of
such disproportionately impacted Holder (or group of Holders) shall be required. If a Registration Statement does not register all of
the Registrable Securities pursuant to a waiver or amendment done in compliance with the previous sentence, then the number of Registrable
Securities to be registered for each Holder shall be reduced pro rata among all Holders and each Holder shall have the right to designate
which of its Registrable Securities shall be omitted from such Registration Statement. Notwithstanding the foregoing, a waiver or consent
to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of a Holder or some Holders and
that does not directly or indirectly affect the rights of other Holders may be given only by such Holder or Holders of all of the Registrable
Securities to which such waiver or consent relates; provided, however, that the provisions of this sentence may not be
amended, modified, or supplemented except in accordance with the provisions of the first sentence of this Section 6(d). No consideration
shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of this Agreement unless the
same consideration also is offered to all of the parties to this Agreement.

 

(e)              
Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall
be delivered as set forth in the Subscription Agreement.

 

(f)               
Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns
of each of the parties and shall inure to the benefit of each Holder. The Company may not assign (except by merger) its rights or obligations
hereunder without the prior written consent of all of the Holders of the then outstanding Registrable Securities. Each Holder may assign
their respective rights hereunder in the manner and to the Persons as permitted under Section 5.17 of the Subscription Agreement.

 

(g)              
No Inconsistent Agreements. Except previously disclosed to the Purchasers, neither the Company nor any of its Subsidiaries
has entered, as of the date hereof, nor shall the Company or any of its Subsidiaries, on or after the date of this Agreement, enter into
any agreement with respect to its securities, that would have the effect of impairing the rights granted to the Holders in this Agreement
or otherwise conflicts with the provisions hereof. Except as set forth on Schedule 6(g), neither the Company nor any of its Subsidiaries
has previously entered into any agreement granting any registration rights with respect to any of its securities to any Person that have
not been satisfied in full.

 

    16

     

    

 

(h)              
Execution and Counterparts. This Agreement may be executed in two or more counterparts, all of which when taken together
shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered
to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered
by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding
obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile
or “.pdf” signature page were an original thereof.

 

(i)                
Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall
be determined in accordance with the provisions of the Subscription Agreement.

 

(j)                
Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any other remedies provided by law.

 

(k)              
Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction
to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall
remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would
have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared
invalid, illegal, void or unenforceable.

 

(l)                
Headings. The headings in this Agreement are for convenience only, do not constitute a part of the Agreement and shall
not be deemed to limit or affect any of the provisions hereof.

 

    17

     

    

 

(m)            
Independent Nature of Holders’ Obligations and Rights. The obligations of each Holder hereunder are several and not
joint with the obligations of any other Holder hereunder, and no Holder shall be responsible in any way for the performance of the obligations
of any other Holder hereunder. Nothing contained herein or in any other agreement or document delivered at any closing, and no action
taken by any Holder pursuant hereto or thereto, shall be deemed to constitute the Holders as a partnership, an association, a joint venture
or any other kind of group or entity, or create a presumption that the Holders are in any way acting in concert or as a group or entity
with respect to such obligations or the transactions contemplated by this Agreement or any other matters, and the Company acknowledges
that the Holders are not acting in concert or as a group, and the Company shall not assert any such claim, with respect to such obligations
or transactions. Each Holder shall be entitled to protect and enforce its rights, including without limitation the rights arising out
of this Agreement, and it shall not be necessary for any other Holder to be joined as an additional party in any proceeding for such
purpose. The use of a single agreement with respect to the obligations of the Company contained was solely in the control of the Company,
not the action or decision of any Holder, and was done solely for the convenience of the Company and not because it was required or requested
to do so by any Holder. It is expressly understood and agreed that each provision contained in this Agreement is between the Company
and a Holder, solely, and not between the Company and the Holders collectively and not between and among Holders.

Annex A

 

Plan of Distribution

 

Each Selling Shareholder
(the “Selling Shareholders”) of the securities and any of their pledgees, assignees and successors-in-interest may,
from time to time, sell any or all of their securities covered hereby on the principal trading market or any other stock exchange, market
or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices.
A Selling Shareholder may use any one or more of the following methods when selling securities:

 

		·	ordinary brokerage
                                            transactions and transactions in which the broker-dealer solicits purchasers;

 

		·	block trades in which
                                            the broker-dealer will attempt to sell the securities as agent but may position and resell
                                            a portion of the block as principal to facilitate the transaction;

 

		·	purchases by a broker-dealer
                                            as principal and resale by the broker-dealer for its account;

 

		·	an exchange distribution
                                            in accordance with the rules of the applicable exchange;

 

		·	privately negotiated
                                            transactions;

 

		·	settlement of short
                                            sales;

 

		·	in transactions through
                                            broker-dealers that agree with the Selling Shareholders to sell a specified number of
                                            such securities at a stipulated price per security;

 

		·	through the writing
                                            or settlement of options or other hedging transactions, whether through an options exchange
                                            or otherwise;

 

		·	a combination of any
                                            such methods of sale; or

 

		·	any other method permitted
                                            pursuant to applicable law.

 

The Selling Shareholders
may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended (the “Securities
Act”), if available, rather than under this prospectus.

 

Broker-dealers engaged
by the Selling Shareholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Shareholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser)
in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in
excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or
markdown in compliance with FINRA IM-2440.

 

     

     

    

 

In connection with the sale
of the securities or interests therein, the Selling Shareholders may enter into hedging transactions with broker-dealers or other financial
institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling
Shareholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities
to broker-dealers that in turn may sell these securities. The Selling Shareholders may also enter into option or other transactions with
broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer
or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution
may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

 

The Selling Shareholders
and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the
meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents
and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the
Securities Act. Each Selling Shareholder has informed the Company that it does not have any written or oral agreement or understanding,
directly or indirectly, with any person to distribute the securities.

 

The Company is required to
pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify
the Selling Shareholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

 

We agreed to use commercially
reasonable efforts to keep the registration statement of which this prospectus forms a part effective until the earlier of (i) the date
on which the securities may be resold by the Selling Shareholders without registration and without regard to any volume or manner-of-sale
limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under
Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus
or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered
or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities
covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the
registration or qualification requirement is available and is complied with.

 

Under applicable rules and
regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in
market making activities with respect to the Ordinary Shares for the applicable restricted period, as defined in Regulation M, prior
to the commencement of the distribution. In addition, the Selling Shareholders will be subject to applicable provisions of the Exchange
Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the Ordinary
Shares by the Selling Shareholders or any other person. We will make copies of this prospectus available to the Selling Shareholders
and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including
by compliance with Rule 172 under the Securities Act).

SELLING SHAREHOLDERS

 

The Ordinary Shares being
offered by the selling shareholders are those previously issued to the selling shareholders. For additional information regarding the
issuances of those Ordinary Shares, see “Private Placement of Ordinary Shares” above. We are registering the Ordinary Shares

Shares, the selling shareholders have not had any material relationship with us within the past three years.

 

The table below lists the
selling shareholders and other information regarding the beneficial ownership of the Ordinary Shares by each of the selling shareholders.
The second column lists the number of Ordinary Shares beneficially owned by each selling shareholder, based on its ownership of the Ordinary
Shares, as of ________, 2021.

 

The third column lists the
Ordinary Shares being offered by this prospectus by the selling shareholders.

 

In accordance with the terms
of a registration rights agreement with the selling shareholders, this prospectus generally covers the resale of the number of Ordinary
Shares issued to the selling shareholders in the __________________ as of the trading day immediately preceding the applicable date of
determination and all subject to adjustment as provided in the registration rights agreement. The fourth column assumes the sale of all
of the shares offered by the selling shareholders pursuant to this prospectus.

 

The selling shareholders
may sell all, some or none of their shares in this offering. See "Plan of Distribution."
