Receipts and American Depositary Shares are subject by reason of the date of issuance of the underlying Deposited Securities or otherwise. 

American Depositary Shares evidenced by a Receipt, when the Receipt is properly endorsed or accompanied by proper instruments of transfer,

other distributions or to any notice provided for in this Deposit Agreement and for all other purposes, and neither the Depositary nor the Company shall have any obligation or be subject to any liability under this Deposit Agreement to any Holder of
American Depositary Shares (but only to the Owner of those American Depositary Shares). 
 SECTION 2.2. Deposit of Shares. 

Subject to the terms and conditions of this Deposit Agreement, Shares or evidence of rights to receive Shares may be deposited under this
Deposit Agreement by delivery thereof to any Custodian, accompanied by any appropriate instruments or instructions for transfer, or endorsement, in form satisfactory to the Custodian. 

As conditions of accepting Shares for transfer or deposit, the Depositary may require (i) any certification required by the Depositary

representing those deposited Shares, (iii) evidence satisfactory to the Depositary that those Shares have been re-registered in the books of the Company or the Foreign Registrar in the name of the
Depositary, a Custodian or a nominee of the Depositary or a Custodian, (iv) evidence satisfactory to the Depositary that any necessary approval for the transfer or deposit has been granted by any governmental body in each applicable
jurisdiction and (v) an agreement or assignment, or other instrument satisfactory to the Depositary, that provides for the prompt transfer to the Custodian of any dividend, or right to subscribe for additional Shares or to receive other
property, that any person in whose name those Shares are or have been recorded may thereafter receive upon or in respect of those Shares, or, in lieu thereof, such agreement of indemnity or other agreement as shall be satisfactory to the Depositary.

  
 -7- 

 At the request and risk and expense of a person proposing to deposit Shares, and for the
account of that person, the Depositary may receive certificates for Shares to be deposited, together with the other instruments specified in this Section, for the purpose of forwarding those Share certificates to the Custodian for deposit under this
Deposit Agreement. 
 The Depositary shall instruct each Custodian that, upon each delivery to a Custodian of a certificate or certificates
for Shares to be deposited under this Deposit Agreement, together with the other documents specified in this Section, that Custodian shall, as soon as transfer and recordation can be accomplished, present that certificate or those certificates to
the Company or the Foreign Registrar, if applicable, for transfer and recordation of the Shares being deposited in the name of the Depositary or its nominee or that Custodian or its nominee. 

Deposited Securities shall be held by the Depositary or by a Custodian for the account and to the order of the Depositary or at such other
place or places as the Depositary shall determine. 
 SECTION 2.3. Delivery of American Depositary Shares. 

The Depositary shall instruct each Custodian that, upon receipt by that Custodian of any deposit pursuant to Section 2.2, together with
the other documents or evidence required under that Section, that Custodian shall notify the Depositary of that deposit and the person or persons to whom or upon whose written order American Depositary Shares are deliverable in respect thereof. Upon
receiving a notice of a deposit from a Custodian, or upon the receipt of Shares or evidence of the right to receive Shares by the Depositary, the Depositary, subject to the terms and conditions of this Deposit Agreement, shall deliver, to or upon
the order of the person or persons entitled thereto, the number of American Depositary Shares issuable in respect of that deposit, but only upon payment to the Depositary of the fees and expenses of the Depositary for the delivery of those American
Depositary Shares as provided in Section 5.9, and of all taxes and governmental charges and fees payable in connection with that deposit and the transfer of the deposited Shares. However, the Depositary shall deliver only whole numbers
of American Depositary Shares. 
 SECTION 2.4. Registration of Transfer of American Depositary Shares; Combination and Split-up of Receipts; Interchange of Certificated and Uncertificated American Depositary Shares. 

The Depositary, subject to the terms and conditions of this Deposit Agreement, shall register a transfer of American Depositary Shares on its
transfer books upon (i) in the case of certificated American Depositary Shares, surrender of the Receipt evidencing those American Depositary Shares, by the Owner or by a duly authorized attorney, properly endorsed or accompanied by proper
instruments of transfer or (ii) in the case of uncertificated American Depositary Shares, receipt from the Owner of a proper 

  
 -8- 

 
instruction (including, for the avoidance of doubt, instructions through DRS and Profile as provided in Section 2.9), and, in either case, duly stamped as may be required by the laws of the
State of New York and of the United States of America. Upon registration of a transfer, the Depositary shall deliver the transferred American Depositary Shares to or upon the order of the person entitled thereto. 

The Depositary, subject to the terms and conditions of this Deposit Agreement, shall upon surrender of a Receipt or Receipts for the purpose
of effecting a split-up or combination of such Receipt or Receipts, execute and deliver a new Receipt or Receipts for any authorized number of American Depositary Shares requested, evidencing the same
aggregate number of American Depositary Shares as the Receipt or Receipts surrendered. 
 The Depositary, upon surrender of certificated
American Depositary Shares for the purpose of exchanging for uncertificated American Depositary Shares, shall cancel the Receipt evidencing those certificated American Depositary Shares and send the Owner a statement confirming that the Owner is the
owner of the same number of uncertificated American Depositary Shares. The Depositary, upon receipt of a proper instruction (including, for the avoidance of doubt, instructions through DRS and Profile as provided in Section 2.9) from the Owner
of uncertificated American Depositary Shares for the purpose of exchanging for certificated American Depositary Shares, shall cancel those uncertificated American Depositary Shares and register and deliver to the Owner a Receipt evidencing the same
number of certificated American Depositary Shares. 
 The Depositary may appoint one or more
co-transfer agents for the purpose of effecting registration of transfers of American Depositary Shares and combinations and split-ups of Receipts at designated transfer
offices on behalf of the Depositary, and the Depositary shall notify the Company if it makes an appointment of that kind. In carrying out its functions, a co-transfer agent may require evidence of authority
and compliance with applicable laws and other requirements by Owners or persons entitled to American Depositary Shares and will be entitled to protection and indemnity to the same extent as the Depositary. The Depositary shall require each co-transfer agent that it appoints under this Section 2.4 to give written notice to the Depositary accepting its appointment and agreeing to abide by the applicable terms and conditions of this Deposit
Agreement. 
 SECTION 2.5. Surrender of American Depositary Shares and Withdrawal of Deposited Securities. 

Upon surrender of American Depositary Shares for the purpose of withdrawal of the Deposited Securities represented thereby and payment of the
fee of the Depositary for the surrender of American Depositary Shares as provided in Section 5.9 and payment of all taxes and governmental charges payable in connection with that surrender and withdrawal of the Deposited Securities, and subject
to the terms and conditions of this Deposit Agreement, the Owner of those American Depositary Shares shall be entitled to delivery (to the extent delivery can then be lawfully and practicably made), to or as

  
 -9- 

 
instructed by that Owner, of the amount of Deposited Securities at the time represented by those American Depositary Shares, but not any money or other property as to which a record date
for distribution to Owners has passed (since money or other property of that kind will be delivered or paid on the scheduled payment date to the Owner as of that record date), and except that the Depositary shall not be required to accept
surrender of American Depositary Shares for the purpose of withdrawal to the extent it would require delivery of a fraction of a Deposited Security. That delivery shall be made, as provided in this Section, without unreasonable delay. 

As a condition of accepting a surrender of American Depositary Shares for the purpose of withdrawal of Deposited Securities, the Depositary
may require (i) that each surrendered Receipt be properly endorsed in blank or accompanied by proper instruments of transfer in blank and (ii) that the surrendering Owner execute and deliver to the Depositary a written order directing the
Depositary to cause the Deposited Securities being withdrawn to be delivered to or upon the written order of a person or persons designated in that order. 

Thereupon, the Depositary shall direct the Custodian to deliver, subject to Sections 2.6, 3.1 and 3.2, the other terms and conditions of this
Deposit Agreement and local market rules and practices, to the surrendering Owner or to or upon the written order of the person or persons designated in the order delivered to the Depositary as above provided, the amount of Deposited Securities
represented by the surrendered American Depositary Shares, and the Depositary may charge the surrendering Owner a fee and its expenses for giving that direction by cable (including SWIFT) or facsimile transmission. 

If Deposited Securities are delivered physically upon surrender of American Depositary Shares for the purpose of withdrawal, that delivery
will be made at the Custodian’s office, except that, at the request, risk and expense of an Owner surrendering American Depositary Shares for withdrawal of Deposited Securities, and for the account of that Owner, the Depositary shall
direct the Custodian to forward any cash or other property comprising, and forward a certificate or certificates, if applicable, and other proper documents of title, if any, for, the Deposited Securities represented by the surrendered American
Depositary Shares to the Depositary for delivery at the Depositary’s Office or to another address specified in the order received from the surrendering Owner. 

SECTION 2.6. Limitations on Delivery and Registration, Transfer and Surrender of American Depositary Shares. 

As a condition precedent to the delivery, registration of transfer or surrender of any American Depositary Shares or split-up or combination of any Receipt or withdrawal of any Deposited Securities, the Depositary, Custodian or Registrar may require payment from the depositor of Shares or the presenter of the Receipt or
instruction for registration of transfer or surrender of American Depositary Shares not evidenced by a Receipt of a sum sufficient to reimburse it for any tax or other governmental charge and any stock transfer or registration fee with respect
thereto (including any such tax or charge 

  
 -10- 

 
and fee with respect to Shares being deposited or withdrawn) and payment of any applicable fees as provided in this Deposit Agreement, may require the production of proof satisfactory to it as to
the identity and genuineness of any signature and may also require compliance with any regulations the Depositary may establish consistent with the provisions of this Deposit Agreement, including, without limitation, this Section 2.6. 

The Depositary may refuse to accept deposits of Shares for delivery of American Depositary Shares, refuse to register transfers of American
Depositary Shares in particular instances, or suspend deposits of Shares or registration of transfer generally, whenever it or the Company considers it necessary or advisable to do so. The Depositary may refuse surrenders of American Depositary
Shares for the purpose of withdrawal of Deposited Securities in particular instances, or may suspend surrenders for the purpose of withdrawal generally, but, notwithstanding anything to the contrary in this Deposit Agreement, only for
(i) temporary delays caused by closing of the Depositary’s register or the register of holders of Shares maintained by the Company or the Foreign Registrar, or the deposit of Shares, in connection with voting at a shareholders’
meeting or the payment of dividends, (ii) the payment of fees, taxes and similar charges, (iii) compliance with any U.S. or foreign laws or governmental regulations relating to the American Depositary Shares or to the withdrawal of the
Deposited Securities or (iv) any other reason that, at the time, is permitted under paragraph I(A)(1) of the General Instructions to Form F-6 under the Securities Act of 1993 or any successor to that
provision. 
 The Depositary shall not knowingly accept for deposit under this Deposit Agreement any Shares that, at the time of deposit,
are Restricted Securities. 
 SECTION 2.7. Lost Receipts, etc. 

If a Receipt is mutilated, destroyed, lost or stolen, the Depositary shall deliver to the Owner the American Depositary Shares evidenced by
that Receipt in uncertificated form or, if requested by the Owner, execute and deliver a new Receipt of like tenor in exchange and substitution for such mutilated Receipt, upon surrender and cancellation of that mutilated Receipt, or in lieu of and
in substitution for that destroyed, lost or stolen Receipt. However, before the Depositary will deliver American Depositary Shares in uncertificated form or execute and deliver a new Receipt, in substitution for a destroyed, lost or stolen
Receipt, the Owner must (a) file with the Depositary (i) a request for that replacement before the Depositary has notice that the Receipt has been acquired by a bona fide purchaser and (ii) a sufficient indemnity bond and
(b) satisfy any other reasonable requirements imposed by the Depositary. 
 SECTION 2.8. Cancellation and Destruction of Surrendered
Receipts. 
 The Depositary shall cancel all Receipts surrendered to it and is authorized to destroy Receipts so cancelled. 

  
 -11- 

 SECTION 2.9. DTC Direct Registration System and Profile Modification System.

 (a) Notwithstanding the provisions of Section 2.4, the parties acknowledge that DTC’s Direct Registration System
(“DRS”) and Profile Modification System (“Profile”) apply to the American Depositary Shares upon acceptance thereof to DRS by DTC. DRS is the system administered by DTC that facilitates interchange between
registered holding of uncertificated securities and holding of security entitlements in those securities through DTC and a DTC participant. Profile is a required feature of DRS that allows a DTC participant, claiming to act on behalf of an Owner of
American Depositary Shares, to direct the Depositary to register a transfer of those American Depositary Shares to DTC or its nominee and to deliver those American Depositary Shares to the DTC account of that DTC participant without receipt by the
Depositary of prior authorization from the Owner to register that transfer. 
 (b) In connection with DRS/Profile, the parties acknowledge
that the Depositary will not determine whether the DTC participant that is claiming to be acting on behalf of an Owner in requesting a registration of transfer and delivery as described in paragraph (a) above has the actual authority to act on
behalf of that Owner (notwithstanding any requirements under the Uniform Commercial Code). For the avoidance of doubt, the provisions of Sections 5.3 and 5.8 apply to the matters arising from the use of the DRS/Profile. The parties agree that the
Depositary’s reliance on and compliance with instructions received by the Depositary through the DRS/Profile system and otherwise in accordance with this Deposit Agreement shall not constitute negligence or bad faith on the part of the
Depositary. 
 ARTICLE 3. CERTAIN OBLIGATIONS OF OWNERS AND HOLDERS OF AMERICAN DEPOSITARY SHARES 

SECTION 3.1. Filing Proofs, Certificates and Other Information. 

Any person presenting Shares for deposit or any Owner or Holder may be required from time to time to file with the Depositary or the Custodian
such proof of citizenship or residence, exchange control approval, or such information relating to the registration on the books of the Company or the Foreign Registrar, if applicable, to execute such certificates and to make such representations
and warranties, as the Depositary may deem necessary or proper. The Depositary may withhold the delivery or registration of transfer of American Depositary Shares, the distribution of any dividend or other distribution or of the proceeds thereof or
the delivery of any Deposited Securities until that proof or other information is filed or those certificates are executed or those representations and warranties are made. Upon reasonable request of the Company, the Depositary shall provide to the
Company, as promptly as practicable upon its written request, copies of any such proofs of citizenship or residence, or exchange control approval that it receives pursuant to this Section 3.1, to the extent that disclosure is permitted under
applicable law. Each Owner and Holder agrees to provide any information requested by the Depositary pursuant to this Section 3.1. 

  
 -12- 

 SECTION 3.2. Liability of Owner for Taxes. 

If any tax or other governmental charge shall become payable by the Custodian or the Depositary with respect to or in connection with any
American Depositary Shares or any Deposited Securities represented by any American Depositary Shares or in connection with a transaction to which Section 4.8 applies, that tax or other governmental charge shall be payable by the Owner of those
American Depositary Shares to the Depositary. The Depositary may refuse to register any transfer of those American Depositary Shares or any withdrawal of Deposited Securities represented by those American Depositary Shares until that payment is
made, and may withhold any dividends or other distributions or the proceeds thereof, or may sell for the account of the Owner any part or all of the Deposited Securities represented by those American Depositary Shares and apply those dividends or
other distributions or the net proceeds of any sale of that kind in payment of that tax or other governmental charge but, even after a sale of that kind, the Owner of those American Depositary Shares shall remain liable for any deficiency.
The Depositary shall distribute any net proceeds of a sale made under this Section that are not used to pay taxes or governmental charges to the Owners entitled to them in accordance with Section 4.1. If the number of Shares represented by each
American Depositary Share decreases as a result of a sale of Deposited Securities under this Section, the Depositary may call for surrender of the American Depositary Shares to be exchanged on a mandatory basis for a lesser number of American
Depositary Shares and may sell American Depositary Shares to the extent necessary to avoid distributing fractions of American Depositary Shares in that exchange and distribute the net proceeds of that sale to the Owners entitled to them. 

SECTION 3.3. Warranties on Deposit of Shares. 

Every person depositing Shares under this Deposit Agreement shall be deemed thereby to represent and warrant that those Shares and each
certificate therefor, if applicable, are validly issued, fully paid and nonassessable and were not issued in violation of any preemptive or similar rights of the holders of outstanding securities of the Company and that the person making that
deposit is duly authorized so to do. Every depositing person shall also be deemed to represent that the Shares, at the time of deposit, are not Restricted Securities. All representations and warranties deemed made under this Section shall survive
the deposit of Shares and delivery of American Depositary Shares. 
 SECTION 3.4. Disclosure of Interests. 

When required in order to comply with applicable laws and regulations, the rules and requirements of the Nasdaq Stock Market LLC or any other
stock exchange on which the Shares or the American Depositary Shares are registered or the articles of association or similar document of the Company, the Company may from time to time 

  
 -13- 

 
request each Owner and Holder to provide to the Depositary information relating to: (a) the capacity in which it holds American Depositary Shares, (b) the identity of any
Holders or other persons or entities then or previously interested in those American Depositary Shares and the nature of those interests and (c) any other matter where disclosure of such matter is required for that
compliance. Each Owner and Holder agrees to provide all information known to it in response to a request made pursuant to this Section. Each Holder consents to the disclosure by the Depositary, the Owner or any other Holder through
which it holds American Depositary Shares, directly or indirectly, of all information responsive to a request made pursuant to this Section relating to that Holder that is known to that Owner or other Holder. The Depositary agrees to use
reasonable efforts to comply with written instructions requesting that the Depositary forward any request authorized under this Section to the Owners and to forward to the Company any responses it receives in response to that request. The
Depositary may charge the Company a fee and its expenses for complying with requests under this Section 3.4. 
 ARTICLE 4. THE
DEPOSITED SECURITIES 
 SECTION 4.1. Cash Distributions. 

Whenever the Depositary receives any cash dividend or other cash distribution on Deposited Securities, the Depositary shall, subject to the
provisions of Section 4.5, convert that dividend or other distribution into Dollars and distribute the amount thus received (net of the fees and expenses of the Depositary as provided in Section 5.9) to the Owners entitled thereto, in
proportion to the number of American Depositary Shares representing those Deposited Securities held by them respectively; provided, however, that if the Custodian or the Depositary shall be required to withhold and does withhold from
that cash dividend or other cash distribution an amount on account of taxes or other governmental charges, the amount distributed to the Owners of the American Depositary Shares representing those Deposited Securities shall be reduced accordingly.
However, the Depositary will not pay any Owner a fraction of one cent, but will round each Owner’s entitlement to the nearest whole cent. 

The Company or its agent will remit to the appropriate governmental agency in each applicable jurisdiction all amounts withheld and owing to
such agency. 
 If a cash distribution would represent a return of all or substantially all the value of the Deposited Securities
underlying American Depositary Shares, the Depositary may: 
 (i) require payment of or deduct the fee for surrender of American Depositary
Shares (whether or not it is also requiring surrender of American Depositary Shares) as a condition of making that cash distribution; or 

(ii) sell all Deposited Securities other than the subject cash distribution and add any net cash proceeds of that sale to the cash
distribution, call for surrender of all those American Depositary Shares and require that surrender as a condition of making that cash distribution. 

  
 -14- 

 If the Depositary acts under this paragraph, that action shall also be a Termination Option Event.

 SECTION 4.2. Distributions Other Than Cash, Shares or Rights. 

Subject to the provisions of Sections 4.11 and 5.9, whenever the Depositary receives any distribution other than a distribution described in
Section 4.1, 4.3 or 4.4 on Deposited Securities (but not in exchange for or in conversion or in lieu of Deposited Securities), the Depositary shall cause the securities or property received by it to be distributed to the Owners entitled
thereto, after deduction or upon payment of any fees and expenses of the Depositary and any taxes or other governmental charges, in proportion to the number of American Depositary Shares representing such Deposited Securities held by them
respectively, in any manner that the Depositary deems equitable and practicable for accomplishing that distribution (which may be a distribution of depositary shares representing the securities received); provided, however, that if in
the opinion of the Depositary such distribution cannot be made proportionately among the Owners entitled thereto, or if for any other reason (including, but not limited to, any requirement that the Company or the Depositary withhold an amount on
account of taxes or other governmental charges or that securities received must be registered under the Securities Act of 1933 in order to be distributed to Owners or Holders) the Depositary, after consultation with the Company to the extent
practicable, deems such distribution not to be lawful and feasible, the Depositary may adopt such other method as it may deem equitable and practicable for the purpose of effecting such distribution, including, but not limited to, the public or
private sale of the securities or property thus received, or any part thereof, and distribution of the net proceeds of any such sale (net of the fees and expenses of the Depositary as provided in Section 5.9) to the Owners entitled thereto, all
in the manner and subject to the conditions set forth in Section 4.1. The Depositary may withhold any distribution of securities under this Section 4.2 if it has not received satisfactory assurances from the Company that the distribution
does not require registration under the Securities Act of 1933. The Depositary may sell, by public or private sale, an amount of securities or other property it would otherwise distribute under this Section 4.2 that is sufficient to pay its
fees and expenses in respect of that distribution. 
 If a distribution to be made under this Section 4.2 would represent a return of
all or substantially all the value of the Deposited Securities underlying American Depositary Shares, the Depositary may: 
 (i) require
payment of or deduct the fee for surrender of American Depositary Shares (whether or not it is also requiring surrender of American Depositary Shares) as a condition of making that distribution; or 

  
 -15- 

 (ii) sell all Deposited Securities other than the subject distribution and add any net cash
proceeds of that sale to the distribution, call for surrender of all those American Depositary Shares and require that surrender as a condition of making that distribution. 

If the Depositary acts under this paragraph, that action shall also be a Termination Option Event. 

SECTION 4.3. Distributions in Shares. 

Whenever the Depositary receives any distribution on Deposited Securities consisting of a dividend in, or free distribution of, Shares, the
Depositary may deliver to the Owners entitled thereto, in proportion to the number of American Depositary Shares representing those Deposited Securities held by them respectively, an aggregate number of American Depositary Shares representing the
amount of Shares received as that dividend or free distribution, subject to the terms and conditions of this Deposit Agreement with respect to the deposit of Shares and issuance of American Depositary Shares, including withholding of any tax or
governmental charge as provided in Section 4.11 and payment of the fees and expenses of the Depositary as provided in Section 5.9 (and the Depositary may sell, by public or private sale, an amount of the Shares received (or American
Depositary Shares representing those Shares) sufficient to pay its fees and expenses in respect of that distribution). In lieu of delivering fractional American Depositary Shares, the Depositary may sell the amount of Shares represented by the
aggregate of those fractions (or American Depositary Shares representing those Shares) and distribute the net proceeds, all in the manner and subject to the conditions described in Section 4.1. If and to the extent that additional American
Depositary Shares are not delivered and Shares or American Depositary Shares are not sold, each American Depositary Share shall thenceforth also represent the additional Shares distributed on the Deposited Securities represented thereby. 

If the Company declares a distribution in which holders of Deposited Securities have a right to elect whether to receive cash, Shares or
other securities or a combination of those things, or a right to elect to have a distribution sold on their behalf, the Depositary may, after consultation with the Company, make that right of election available for exercise by Owners in any manner
the Depositary considers to be lawful and practical. As a condition of making a distribution election right available to Owners, the Depositary may require satisfactory assurances from the Company that doing so does not require registration of any
securities under the Securities Act of 1933 that has not already been effected. 

  
 -16- 

 SECTION 4.4. Rights. 

(a) If rights are granted to the Depositary in respect of deposited Shares to purchase additional Shares or other securities, the Company and
the Depositary shall endeavor to consult as to the actions, if any, the Depositary should take in connection with that grant of rights. The Depositary may, to the extent deemed by it to be lawful and practical (i) if requested in writing by the
Company, grant to all or certain Owners rights to instruct the Depositary to purchase the securities to which the rights relate and deliver those securities or American Depositary Shares representing those securities to Owners, (ii) if
requested in writing by the Company, deliver the rights to or to the order of certain Owners, or (iii) sell the rights to the extent practicable and distribute the net proceeds of that sale to Owners entitled to those proceeds. To the extent
rights are not exercised, delivered or disposed of under (i), (ii) or (iii) above, the Depositary shall permit the rights to lapse unexercised. 

(b) If the Depositary will act under (a)(i) above, the Company and the Depositary will enter into a separate agreement setting forth the
conditions and procedures applicable to the particular offering. Upon instruction from an applicable Owner in the form the Depositary specified and upon payment by that Owner to the Depositary of an amount equal to the purchase price of the
securities to be received upon the exercise of the rights, the Depositary shall, on behalf of that Owner, exercise the rights and purchase the securities. The purchased securities shall be delivered to, or as instructed by, the Depositary. The
Depositary shall (i) deposit the purchased Shares under this Deposit Agreement and deliver American Depositary Shares representing those Shares to that Owner or (ii) deliver or cause the purchased Shares or other securities to be delivered
to or to the order of that Owner. The Depositary will not act under (a)(i) above unless the offer and sale of the securities to which the rights relate are registered under the Securities Act of 1933 or the Depositary has received an opinion of
United States counsel that is satisfactory to it to the effect that those securities may be sold and delivered to the applicable Owners without registration under the Securities Act of 1933. 

(c) If the Depositary will act under (a)(ii) above, the Company and the Depositary will enter into a separate agreement setting forth the
conditions and procedures applicable to the particular offering. Upon (i) the request of an applicable Owner to deliver the rights allocable to the American Depositary Shares of that Owner to an account specified by that Owner to which the
rights can be delivered and (ii) receipt of such documents as the Company and the Depositary agreed to require to comply with applicable law, the Depositary will deliver those rights as requested by that Owner. 

(d) If the Depositary will act under (a)(iii) above, the Depositary will use reasonable efforts to sell the rights in proportion to the number
of American Depositary Shares held by the applicable Owners and pay the net proceeds to the Owners otherwise entitled to the rights that were sold, upon an averaged or other practical basis without regard to any distinctions among such Owners
because of exchange restrictions or the date of delivery of any American Depositary Shares or otherwise. 

  
 -17- 

 (e) Payment or deduction of the fees of the Depositary as provided in Section 5.9 and
payment or deduction of the expenses of the Depositary and any applicable taxes or other governmental charges shall be conditions of any delivery of securities or payment of cash proceeds under this Section 4.4. 

(f) The Depositary shall not be responsible for any failure to determine that it may be lawful or feasible to make rights available to or
exercise rights on behalf of Owners in general or any Owner in particular, or to sell rights. 
 SECTION 4.5. Conversion of Foreign
Currency. 
 Whenever the Depositary or the Custodian receives foreign currency, by way of dividends or other distributions or the net
proceeds from the sale of securities, property or rights, and if at the time of the receipt thereof the foreign currency so received can in the judgment of the Depositary be converted on a reasonable basis into Dollars and the resulting Dollars
transferred to the United States, the Depositary or one of its agents or affiliates or the Custodian shall convert or cause to be converted by sale or in any other manner that it may determine that foreign currency into Dollars, and those Dollars
shall be distributed to the Owners entitled thereto. A cash distribution may be made upon an averaged or other practicable basis without regard to any distinctions among Owners based on exchange restrictions, the date of delivery of any
American Depositary Shares or otherwise and shall be net of any expenses of conversion into Dollars incurred by the Depositary as provided in Section 5.9. 

If a conversion of foreign currency or the repatriation or distribution of Dollars can be effected only with the approval or license of any
government or agency thereof, the Depositary may, but will not be required to, file an application for that approval or license. 
 If the
Depositary determines that in its judgment any foreign currency received by the Depositary or the Custodian is not convertible on a reasonable basis into Dollars transferable to the United States, or if any approval or license of any government or
agency thereof that is required for such conversion is not filed or sought by the Depositary or is not obtained within a reasonable period as determined by the Depositary, the Depositary may distribute the foreign currency received by the Depositary
to, or in its discretion may hold such foreign currency uninvested and without liability for interest thereon for the respective accounts of, the Owners entitled to receive the same. 

If any conversion of foreign currency, in whole or in part, cannot be effected for distribution to some of the Owners entitled thereto, the
Depositary may in its discretion make that conversion and distribution in Dollars to the extent practicable and permissible to the Owners entitled thereto and may distribute the balance of the foreign currency received by the Depositary to, or hold
that balance uninvested and without liability for interest thereon for the account of, the Owners entitled thereto. 
 The Depositary may
convert currency itself or through any of its affiliates, or the Custodian or the Company may convert currency and pay Dollars to the Depositary. 

  
 -18- 

 
Where the Depositary converts currency itself or through any of its affiliates, the Depositary acts as principal for its own account and not as agent, advisor, broker or fiduciary on behalf of
any other person and earns revenue, including, without limitation, transaction spreads, that it will retain for its own account. The revenue is based on, among other things, the difference between the exchange rate assigned to the currency
conversion made under this Deposit Agreement and the rate that the Depositary or its affiliate receives when buying or selling foreign currency for its own account. The Depositary makes no representation that the exchange rate used or obtained
by it or its affiliate in any currency conversion under this Deposit Agreement will be the most favorable rate that could be obtained at the time or that the method by which that rate will be determined will be the most favorable to Owners, subject
to the Depositary’s obligations under Section 5.3. The methodology used to determine exchange rates used in currency conversions made by the Depositary is available upon request. Where the Custodian converts currency, the Custodian
has no obligation to obtain the most favorable rate that could be obtained at the time or to ensure that the method by which that rate will be determined will be the most favorable to Owners, and the Depositary makes no representation that the rate
is the most favorable rate and will not be liable for any direct or indirect losses associated with the rate. In certain instances, the Depositary may receive dividends or other distributions from the Company in Dollars that represent the
proceeds of a conversion of foreign currency or translation from foreign currency at a rate that was obtained or determined by or on behalf of the Company and, in such cases, the Depositary will not engage in, or be responsible for, any foreign
currency transactions and neither it nor the Company makes any representation that the rate obtained or determined by the Company is the most favorable rate and neither it nor the Company will be liable for any direct or indirect losses associated
with the rate. 
 SECTION 4.6. Fixing of Record Date. 

Whenever a cash dividend, cash distribution or any other distribution is made on Deposited Securities or rights to purchase Shares or other
securities are issued with respect to Deposited Securities (which rights will be delivered to or exercised or sold on behalf of Owners in accordance with Section 4.4) or the Depositary receives notice that a distribution or issuance of that
kind will be made, or whenever the Depositary receives notice that a meeting of holders of Shares will be held in respect of which the Company has requested the Depositary to send a notice under Section 4.7, or whenever the Depositary will
assess a fee or charge against the Owners, or whenever the Depositary causes a change in the number of Shares that are represented by each American Depositary Share, or whenever the Depositary otherwise finds it necessary or convenient, the
Depositary shall fix a record date, which shall be the same as, or as near as practicable to, any corresponding record date set by the Company with respect to Shares, (a) for the determination of the Owners (i) who shall be entitled to
receive the benefit of that dividend or other distribution or those rights, (ii) who shall be entitled to give instructions for the exercise of voting rights at that meeting, (iii) who shall be responsible for that fee or charge or
(iv) for any other purpose for which the record date was set, or (b) on or after which 

  
 -19- 

 
each American Depositary Share will represent the changed number of Shares. Subject to the provisions of Sections 4.1 through 4.5 and to the other terms and conditions of this Deposit Agreement,
the Owners on a record date fixed by the Depositary shall be entitled to receive the amount distributable by the Depositary with respect to that dividend or other distribution or those rights or the net proceeds of sale thereof in proportion to the
number of American Depositary Shares held by them respectively, to give voting instructions or to act in respect of the other matter for which that record date was fixed, or be responsible for that fee or charge, as the case may be. 

SECTION 4.7. Voting of Deposited Shares. 

(a) Upon receipt of notice of any meeting of holders of Shares at which holders of Shares will be entitled to vote, if requested in writing by
the Company, the Depositary shall, as soon as practicable thereafter, Disseminate to the Owners a notice, the form of which shall be in the sole discretion of the Depositary, that shall contain (i) the information contained in the notice
of meeting received by the Depositary, (ii) a statement that the Owners as of the close of business on a specified record date will be entitled, subject to any applicable provision of the laws of England and Wales and of the articles of
association or similar documents of the Company, to instruct the Depositary as to the exercise of the voting rights pertaining to the amount of Shares represented by their respective American Depositary Shares (iii) a statement as to the manner
in which those instructions may be given, including an express indication that instructions may be deemed given in accordance with the last sentence of paragraph (b) below, if no instruction is received, to the Depositary to give a
discretionary proxy to a person designated by the Company and (iv) the last date on which the Depositary will accept instructions (the “Instruction Cutoff Date”). 

(b) Upon the written request of an Owner of American Depositary Shares, as of the date of the request or, if a record date was specified by
the Depositary, as of that record date, received on or before any Instruction Cutoff Date established by the Depositary, the Depositary may, and if the Depositary sent a notice under the preceding paragraph shall, endeavor, in so far
as practicable, to vote or cause to be voted the amount of deposited Shares represented by those American Depositary Shares in accordance with the instructions set forth in that request. The Depositary shall not vote or attempt to exercise the right
to vote that attaches to the deposited Shares other than in accordance with instructions given by Owners and received by the Depositary or as provided in the following sentence. If 

(i) the Company instructed the Depositary to Disseminate a notice under paragraph (a) above and complied with paragraph (d) below,

 (ii) no instructions are received by the Depositary from an Owner with respect to a matter and an amount of American Depositary Shares of
that Owner on or before the Instruction Cutoff Date and 

  
 -20- 

 (iii) the Depositary has received from the Company, by the business day following the
Instruction Cutoff Date, a written confirmation that, as of the Instruction Cutoff Date, (x) the Company wishes a proxy to be given under this sentence, (y) the Company reasonably does not know of any substantial opposition to the matters
and (z) the matters are not materially adverse to the interests of shareholders, 
 then, the Depositary shall deem that Owner to have instructed the
Depositary to give a discretionary proxy to a person designated by the Company with respect to that matter and the amount of deposited Shares represented by that amount of American Depositary Shares and the Depositary shall give a discretionary
proxy to a person designated by the Company to vote that amount of deposited Shares as to that matter. 
 (c) There can be no assurance that
Owners generally or any Owner in particular will receive the notice described in paragraph (a) above in time to enable Owners to give instructions to the Depositary prior to the Instruction Cutoff Date. 

(d) If the Company will request the Depositary to Disseminate a notice under paragraph (a) above, the Company shall give the
Depositary notice of the meeting, details concerning the matters to be voted upon and copies of materials to be made available to holders of Shares in connection with the meeting not less than 45 days prior to the meeting date. 

Notwithstanding anything in this Section 4.7 to the contrary, the Depositary and the Company may modify, amend or adopt additional procedures
relating to voting of deposited Shares from time to time as they determine may be necessary to comply with applicable laws and regulations. 

SECTION 4.8. Tender and Exchange Offers; Redemption, Replacement or Cancellation of Deposited Securities. 

(a) The Depositary shall not tender any Deposited Securities in response to any voluntary cash tender offer, exchange offer or similar offer
made to holders of Deposited Securities (a “Voluntary Offer”), except when instructed in writing to do so by an Owner surrendering American Depositary Shares and subject to any conditions or procedures the Depositary may require.

 (b) If the Depositary receives a written notice that Deposited Securities have been redeemed for cash or otherwise purchased for cash in
a transaction that is mandatory and binding on the Depositary as a holder of those Deposited Securities (a “Redemption”), the Depositary, at the expense of the Company, shall (i) if required, surrender Deposited Securities that
have been redeemed to the issuer of those securities or its agent on the redemption date, (ii) Disseminate a notice to Owners (A) notifying them of that Redemption, (B) calling for surrender of a corresponding number of American
Depositary Shares and (C) notifying them that the called American Depositary Shares have been converted into a right only to receive the money received by the Depositary upon that Redemption and those net proceeds shall be the Deposited
Securities to which Owners of those converted American Depositary Shares shall be entitled upon surrenders of those American Depositary Shares in accordance with Section 2.5 or 6.2 and (iii) distribute the money received upon that
Redemption to the Owners entitled to it upon surrender by them of called American Depositary Shares in accordance with Section 2.5 (and, for the 

  
 -21- 

 
avoidance of doubt, Owners shall not be entitled to receive that money under Section 4.1). If the Redemption affects less than all the Deposited Securities, the Depositary shall call for
surrender a corresponding portion of the outstanding American Depositary Shares and only those American Depositary Shares will automatically be converted into a right to receive the net proceeds of the Redemption. The Depositary shall allocate the
American Depositary Shares converted under the preceding sentence among the Owners pro-rata to their respective holdings of American Depositary Shares immediately prior to the Redemption, except that
the allocations may be adjusted so that no fraction of a converted American Depositary Share is allocated to any Owner. A Redemption of all or substantially all of the Deposited Securities shall be a Termination Option Event. 

(c) If the Depositary is notified of or there occurs any change in nominal value or any subdivision, combination or any other reclassification
of the Deposited Securities or any recapitalization, reorganization, sale of assets substantially as an entirety, merger or consolidation affecting the issuer of the Deposited Securities or to which it is a party that is mandatory and binding on the
Depositary as a holder of Deposited Securities and, as a result, securities or other property have been or will be delivered in exchange, conversion, replacement or in lieu of, Deposited Securities (a “Replacement”), the Depositary
shall, if required, surrender the old Deposited Securities affected by that Replacement of Shares and hold, as new Deposited Securities under this Deposit Agreement, the new securities or other property delivered to it in that Replacement.
However, the Depositary may elect to sell those new Deposited Securities if in the opinion of the Depositary, after consultation with the Company to the extent practicable, it is not lawful or not practical for it to hold those new Deposited
Securities under this Deposit Agreement because those new Deposited Securities may not be distributed to Owners without registration under the Securities Act of 1933 or for any other reason, at public or private sale, at such places and on such
terms as it deems proper and proceed as if those new Deposited Securities had been Redeemed under paragraph (b) above. A Replacement shall be a Termination Option Event. 

(d) In the case of a Replacement where the new Deposited Securities will continue to be held under this Deposit Agreement, the Depositary may,
after consultation with the Company to the extent practicable, call for the surrender of outstanding Receipts to be exchanged for new Receipts specifically describing the new Deposited Securities and the number of those new Deposited Securities
represented by each American Depositary Share. If the number of Shares represented by each American Depositary Share decreases as a result of a Replacement, the Depositary may call for surrender of the American Depositary Shares to be exchanged on a
mandatory basis for a lesser number of American Depositary Shares and may sell American Depositary Shares to the extent necessary to avoid distributing fractions of American Depositary Shares in that exchange and distribute the net proceeds of that
sale to the Owners entitled to them. 

  
 -22- 

 (e) If there are no Deposited Securities with respect to American Depositary Shares,
including if the Deposited Securities are cancelled, or the Deposited Securities with respect to American Depositary Shares have become apparently worthless, the Depositary may call for surrender of those American Depositary Shares or may cancel
those American Depositary Shares, upon notice to Owners, and that condition shall be a Termination Option Event. 
 SECTION 4.9.
Reports. 
 The Depositary shall make available for inspection by Owners at its Office any reports and communications, including any
proxy solicitation material, received from the Company which are both (a) received by the Depositary as the holder of the Deposited Securities and (b) made generally available to the holders of those Deposited Securities by the Company.
The Company shall furnish reports and communications, including any proxy soliciting material to which this Section applies, to the Depositary in English, to the extent those materials are required to be translated into English pursuant to any
regulations of the Commission. 
 SECTION 4.10. Lists of Owners. 

Upon written request by the Company (unless otherwise agreed between the Company and the Depositary), the Depositary shall, at the expense of
the Company, furnish to it a list, as of a recent date, of the names, addresses and American Depositary Share holdings of all Owners. 

SECTION 4.11. Withholding. 

If the Depositary determines that any distribution received or to be made by the Depositary (including Shares and rights to subscribe
therefor) is subject to any tax or other governmental charge that the Depositary is obligated to withhold, the Depositary may sell, by public or private sale, all or a portion of the distributed property (including Shares and rights to subscribe
therefor) in the amounts and manner the Depositary deems necessary and practicable to pay those taxes or charges, and the Depositary shall distribute the net proceeds of that sale, after deduction of those taxes or charges, to the Owners entitled
thereto in proportion to the number of American Depositary Shares held by them respectively. 
 Services for Owners and Holders that may
permit them to obtain reduced rates of tax withholding at source or reclaim excess tax withheld, and the fees and costs associated with using services of that kind, are not provided under, and are outside the scope of, this Deposit Agreement. 

Each Owner and Holder agrees to indemnify the Company, the Depositary, the Custodian and their respective directors, employees, agents and
affiliates for, and hold each of them harmless against, any claim by any governmental authority with respect to taxes, additions to tax, penalties or interest arising out of any refund of taxes, reduced withholding at source or other tax benefit

 SECTION 5.6. Notices and Reports. 

If the Company takes or decides to take any corporate action of a kind that is addressed in Sections 4.1 to 4.4, or 4.6 to 4.8, or that

Owners in a manner that the Company specifies as substantially equivalent to the manner in which those communications are made available to holders of Shares and compliant with the requirements of any securities exchange on which the American
Depositary Shares are listed. The Company will timely provide the Depositary with the quantity of such notices, reports, and communications, as requested by the Depositary from time to time, in order for the Depositary to effect that Dissemination.

 The Company represents that as of the date of this Deposit Agreement, the statements in Article 11 of the form of Receipt appearing as
Exhibit A to this Deposit Agreement or, if applicable, most recently filed with the Commission pursuant to Rule 424(b) under the Securities Act of 1933 with respect to the Company’s obligation to file periodic reports under the United
States Securities Exchange Act of 1934, as amended, or its qualification for exemption from registration under that Act pursuant to Rule 12g3-2(b) under that Act, as the case may be, are true and correct. The
Company agrees to promptly notify the Depositary upon becoming aware of any change in the truth of any of those statements or if there is any change in the Company’s status regarding those reporting obligations or that qualification. 

SECTION 5.7. Distribution of Additional Shares, Rights, etc. 

If the Company or any affiliate of the Company determines to make any issuance or distribution of (1) additional Shares, (2) rights
to subscribe for Shares, (3) securities convertible into Shares, or (4) rights to subscribe for such securities (each a “Distribution”), the Company shall notify the Depositary in writing in English as promptly as
practicable and in any event before the Distribution starts and, if requested in writing by the Depositary, the Company shall promptly furnish to the Depositary either (i) evidence satisfactory to the Depositary that the Distribution is
registered under the Securities Act of 1933 or (ii) a written opinion from U.S. counsel for the Company that is reasonably satisfactory to the Depositary, stating that the Distribution does not require, or, if made in the United States, would
not require, registration under the Securities Act of 1933. 

  
 -28- 

 Nothing in this Section 5.7 or elsewhere in this Deposit Agreement shall create any
obligation on the part of the Company to file a registration statement with respect to a Distribution or to endeavor to have such a registration statement declared effective. 

The Company agrees with the Depositary that neither the Company nor any company controlled by, controlling or under common control with the
Company will at any time deposit any Shares that, at the time of deposit, are Restricted Securities. 
 SECTION 5.8. Indemnification.

 The Company agrees to indemnify the Depositary, its directors, employees, agents and affiliates and each Custodian against, and hold each

with (a) any registration with the Commission of American Depositary Shares or Deposited Securities or the offer or sale thereof or (b) acts performed or omitted, pursuant to the provisions of or in connection with this Deposit Agreement
and the American Depositary Shares, as the same may be amended, modified or supplemented from time to time, (i) by either the Depositary or a Custodian or their respective directors, employees, agents and affiliates, except for any liability or
expense arising out of the negligence or bad faith of either of them and except to the extent that any such liability or expense arises out of information relating to the Depositary or the Custodian, furnished in writing to the Company by the
Depositary expressly for use in any registration statement, proxy statement, prospectus (or placement memorandum) or preliminary prospectus (or preliminary placement memorandum) relating to the Shares, or omissions from such information (it being
understood and agreed that, as of the date of this Deposit Agreement, the Depositary has not furnished any information of that kind), or (ii) by the Company or any of its directors, employees, agents and affiliates. 

The Depositary agrees to indemnify the Company, its directors, employees, agents and affiliates and hold them harmless from any liability or
expense that may arise out of acts performed or omitted by the Depositary or any Custodian or their respective directors, employees, agents and affiliates due to their negligence or bad faith. 

Any person seeking indemnification hereunder (an “Indemnified Person”) shall notify the person from whom it is seeking
indemnification (the “Indemnifying Person”) of the commencement of any indemnifiable action or claim promptly after such Indemnified Person becomes aware of such commencement and shall consult in good faith with the Indemnifying Person as
to the conduct of the defense of such action or claim, which defense shall be reasonable under the circumstances. No Indemnified Person shall compromise or settle any such action or claim without the consent in writing of the Indemnifying Person

The form of the Receipts and any provisions of this Deposit Agreement may at any time and from time to time be amended by agreement between
the Company and the Depositary without the consent of Owners or Holders in any respect that they may deem necessary or desirable. Any amendment that would impose or increase any fees or charges (other than taxes and other governmental charges,
registration fees, cable (including SWIFT) or facsimile transmission costs, delivery costs or other such expenses), or that would otherwise prejudice any substantial existing right of Owners, shall, however, not become effective as to outstanding
American Depositary Shares until the expiration of 30 days after notice of that amendment has been Disseminated to the Owners of outstanding American Depositary Shares. Every Owner and Holder, at the time any amendment so becomes effective, shall be
deemed, by continuing to hold American Depositary Shares or any interest therein, to consent and agree to that amendment and to be bound by this Deposit Agreement as amended thereby. Upon the effectiveness of an amendment to the form of Receipt,
including a change in the number of Shares represented by each American Depositary Share, the Depositary may call for surrender of Receipts to be replaced with new Receipts in the amended form or call for surrender of American Depositary Shares to
effect that change of ratio. In no event shall any amendment impair the right of the Owner to surrender American Depositary Shares and receive delivery of the Deposited Securities represented thereby, except in order to comply with mandatory
provisions of applicable law.

 SECTION 6.2. Termination. 

(a) The Company may initiate termination of this Deposit Agreement by notice to the Depositary. The Depositary may initiate termination of
this Deposit Agreement if (i) at any time 60 days shall have expired after the Depositary delivered to the Company a written resignation notice and a successor depositary has not been appointed and accepted its appointment as provided in
Section 5.4 or (ii) a Termination Option Event has occurred or will occur. If termination of this Deposit Agreement is initiated, the Depositary shall Disseminate a notice of termination to the Owners of all American Depositary Shares then
outstanding setting a date for termination (the “Termination Date”), which shall be at least 90 days after the date of that notice, and this Deposit Agreement shall terminate on that Termination Date. 

(b) After the Termination Date, the Company shall be discharged from all obligations under this Deposit Agreement except for its obligations
to the Depositary under Sections 5.8 and 5.9.

Securities then held under this Deposit Agreement and may thereafter hold uninvested the net proceeds of any such sale, together with any other cash then held by it hereunder, unsegregated and without liability for interest, for the pro rata benefit
of the Owners of American Depositary Shares that remain outstanding, and those Owners will be general creditors of the Depositary with respect to those net proceeds and that other cash. After making that sale, the Depositary shall be discharged from
all obligations under this Deposit Agreement, except (i) to account for the net proceeds and other cash (after deducting, in each case, the fee of the Depositary for the surrender of American Depositary Shares, any expenses for the
account of the Owner of such American Depositary Shares in accordance with the terms and conditions of this Deposit Agreement and any applicable taxes or governmental charges) and (ii) for its obligations under Section 5.8 and
(iii) to act as provided in paragraph (d) below. 
 (d) After the Termination Date, the Depositary shall continue to receive
dividends and other distributions pertaining to Deposited Securities (that have not been sold), may sell rights and other property as provided in this Deposit Agreement and shall deliver Deposited Securities (or sale proceeds) upon surrender of
American Depositary Shares (after payment or upon deduction, in each case, of the fee of the Depositary for the surrender of American Depositary Shares, any expenses for the account of the Owner of those American Depositary Shares in accordance with
the terms and conditions of this Deposit Agreement and any applicable taxes or governmental charges). After the Termination Date, the Depositary shall not accept deposits of Shares or deliver American Depositary Shares. After the Termination Date,
(i) the Depositary may refuse to accept surrenders of American Depositary Shares for the purpose of withdrawal of Deposited 

  
 -32- 

 
Securities (that have not been sold) or reverse previously accepted surrenders of that kind that have not settled if in its judgment the requested withdrawal would interfere with its efforts to
sell the Deposited Securities, (ii) the Depositary will not be required to deliver cash proceeds of the sale of Deposited Securities until all Deposited Securities have been sold and (iii) the Depositary may discontinue the registration of
transfers of American Depositary Shares and suspend the distribution of dividends and other distributions on Deposited Securities to the Owners and need not give any further notices or perform any further acts under this Deposit Agreement except as
provided in this Section.

	1.	 THE DEPOSIT AGREEMENT. 

This American Depositary Receipt is one of an issue (herein called “Receipts”), all issued and to be issued upon the terms
and conditions set forth in the Deposit Agreement dated as of __________, 2021 (herein called the “Deposit Agreement”) among the Company, the Depositary, and all Owners and Holders from time to time of American Depositary Shares
issued thereunder, each of whom by accepting American Depositary Shares agrees to become a party thereto and become bound by all the terms and conditions thereof. The Deposit Agreement sets forth the rights of Owners and Holders and the rights and
duties of the Depositary in respect of the Shares deposited thereunder and any and all other securities, property and cash from time to time received in respect of those Shares and held thereunder (those Shares, securities, property, and cash are
herein called “Deposited Securities”). Copies of the Deposit Agreement are on file at the Depositary’s Office in New York City and at the office of the Custodian. 

The statements made on the face and reverse of this Receipt are summaries of certain provisions of the Deposit Agreement and are qualified by

	2.	 SURRENDER OF AMERICAN DEPOSITARY SHARES AND WITHDRAWAL OF SHARES. 

Upon surrender of American Depositary Shares for the purpose of withdrawal of the Deposited Securities represented thereby and payment of the
fee of the Depositary for the surrender of American Depositary Shares as provided in Section 5.9 of the Deposit Agreement and payment of all taxes and governmental charges payable in connection with that surrender and withdrawal of the
Deposited Securities, and subject to the terms and conditions of the Deposit Agreement, the Owner of those American Depositary Shares shall be entitled to delivery (to the extent delivery can then be lawfully and practicably made), to or as
instructed by that Owner, of the amount of Deposited Securities at the time represented by those American Depositary Shares, but not any money or other property as to which a record date for distribution to Owners has passed (since money or
other property of that kind will be delivered or paid on the scheduled payment date to the Owner as of that record date), and except that the Depositary shall not be required to accept surrender of American Depositary Shares for the purpose
of withdrawal to the extent it would require delivery of a fraction of a Deposited Security. The Depositary shall direct the Custodian with respect to delivery of Deposited Securities and may charge the surrendering Owner a fee and its expenses for
giving that direction by cable (including SWIFT) or facsimile transmission. If Deposited Securities are delivered physically upon surrender of American Depositary Shares for the purpose of withdrawal, that delivery will be made at the
Custodian’s office, except that, at the request, risk and expense of the surrendering Owner, and for the account of that Owner, the Depositary shall direct the Custodian to forward any 

  
 A-2 

 
cash or other property comprising, and forward a certificate or certificates, if applicable, and other proper documents of title, if any, for, the Deposited Securities represented by the
surrendered American Depositary Shares to the Depositary for delivery at the Depositary’s Office or to another address specified in the order received from the surrendering Owner. 

 

	3.	 REGISTRATION OF TRANSFER OF AMERICAN DEPOSITARY SHARES; COMBINATION AND
SPLIT-UP OF RECEIPTS; INTERCHANGE OF CERTIFICATED AND UNCERTIFICATED AMERICAN DEPOSITARY SHARES. 

The Depositary, subject to the terms and conditions of the Deposit Agreement, shall register a transfer of American Depositary Shares on its
transfer books upon (i) in the case of certificated American Depositary Shares, surrender of the Receipt evidencing those American Depositary Shares, by the Owner or by a duly authorized attorney, properly endorsed or accompanied by proper
instruments of transfer or (ii) in the case of uncertificated American Depositary Shares, receipt from the Owner of a proper instruction (including, for the avoidance of doubt, instructions through DRS and Profile as provided in
Section 2.9 of that Agreement), and, in either case, duly stamped as may be required by the laws of the State of New York and of the United States of America. Upon registration of a transfer, the Depositary shall deliver the transferred
American Depositary Shares to or upon the order of the person entitled thereto. 
 The Depositary, subject to the terms and conditions of
the Deposit Agreement, shall upon surrender of a Receipt or Receipts for the purpose of effecting a split-up or combination of such Receipt or Receipts, execute and deliver a new Receipt or Receipts for any
authorized number of American Depositary Shares requested, evidencing the same aggregate number of American Depositary Shares as the Receipt or Receipts surrendered. 

The Depositary, upon surrender of certificated American Depositary Shares for the purpose of exchanging for uncertificated American Depositary
Shares, shall cancel the Receipt evidencing those certificated American Depositary Shares and send the Owner a statement confirming that the Owner is the owner of the same number of uncertificated American Depositary Shares. The Depositary, upon
receipt of a proper instruction (including, for the avoidance of doubt, instructions through DRS and Profile as provided in Section 2.9 of the Deposit Agreement) from the Owner of uncertificated American Depositary Shares for the purpose of
exchanging for certificated American Depositary Shares, shall cancel those uncertificated American Depositary Shares and register and deliver to the Owner a Receipt evidencing the same number of certificated American Depositary Shares. 

As a condition precedent to the delivery, registration of transfer, or surrender of any American Depositary Shares or split-up or combination of any Receipt or withdrawal of any Deposited Securities, the Depositary, the Custodian, or Registrar may require payment from the depositor of the Shares or the presenter of the Receipt or
instruction for registration of transfer or surrender of American Depositary Shares not evidenced by a Receipt of a sum sufficient to reimburse it for any tax or other governmental charge and 

  
 A-3 

 
any stock transfer or registration fee with respect thereto (including any such tax or charge and fee with respect to Shares being deposited or withdrawn) and payment of any applicable fees as
provided in the Deposit Agreement, may require the production of proof satisfactory to it as to the identity and genuineness of any signature and may also require compliance with any regulations the Depositary may establish consistent with the
provisions of the Deposit Agreement. 
 The Depositary may refuse to accept deposits of Shares for delivery of American Depositary Shares,
refuse to register transfers of American Depositary Shares in particular instances, or suspend deposits of Shares or registration of transfer generally, whenever it or the Company considers it necessary or advisable to do so. The Depositary may
refuse surrenders of American Depositary Shares for the purpose of withdrawal of Deposited Securities in particular instances, or may suspend surrenders for the purpose of withdrawal generally, but, notwithstanding anything to the contrary in the
Deposit Agreement, only for (i) temporary delays caused by closing of the Depositary’s register or the register of holders of Shares maintained by the Company or the Foreign Registrar, or the deposit of Shares, in connection with
voting at a shareholders’ meeting or the payment of dividends, (ii) the payment of fees, taxes and similar charges, (iii) compliance with any U.S. or foreign laws or governmental regulations relating to the American Depositary Shares
or to the withdrawal of the Deposited Securities or (iv) any other reason that, at the time, is permitted under paragraph I(A)(1) of the General Instructions to Form F-6 under the Securities Act of 1933
or any successor to that provision. 
 The Depositary shall not knowingly accept for deposit under the Deposit Agreement any Shares that, at
the time of deposit, are Restricted Securities. 
  

	4.	 LIABILITY OF OWNER FOR TAXES. 

If any tax or other governmental charge shall become payable by the Custodian or the Depositary with respect to or in connection with any
American Depositary Shares or any Deposited Securities represented by any American Depositary Shares or in connection with a transaction to which Section 4.8 of the Deposit Agreement applies, that tax or other governmental charge shall be
payable by the Owner of those American Depositary Shares to the Depositary. The Depositary may refuse to register any transfer of those American Depositary Shares or any withdrawal of Deposited Securities represented by those American Depositary
Shares until that payment is made, and may withhold any dividends or other distributions or the proceeds thereof, or may sell for the account of the Owner any part or all of the Deposited Securities represented by those American Depositary Shares,
and may apply those dividends or other distributions or the net proceeds of any sale of that kind in payment of that tax or other governmental charge but, even after a sale of that kind, the Owner shall remain liable for any deficiency. The
Depositary shall distribute any net proceeds of a sale made under Section 3.2 of the Deposit Agreement that are not used to pay taxes or governmental charges to the Owners entitled to them in accordance with Section 4.1 of the Deposit
Agreement. If the number of Shares represented by each 

  
 A-4 

 
American Depositary Share decreases as a result of a sale of Deposited Securities under Section 3.2 of the Deposit Agreement, the Depositary may call for surrender of the American Depositary
Shares to be exchanged on a mandatory basis for a lesser number of American Depositary Shares and may sell American Depositary Shares to the extent necessary to avoid distributing fractions of American Depositary Shares in that exchange and
distribute the net proceeds of that sale to the Owners entitled to them. 
  

	5.	 WARRANTIES ON DEPOSIT OF SHARES. 

Every person depositing Shares under the Deposit Agreement shall be deemed thereby to represent and warrant that those Shares and each
certificate therefor, if applicable, are validly issued, fully paid and nonassessable and were not issued in violation of any preemptive or similar rights of the holders of outstanding securities of the Company and that the person making that
deposit is duly authorized so to do. Every depositing person shall also be deemed to represent that the Shares, at the time of deposit, are not Restricted Securities. All representations and warranties deemed made under Section 3.3 of the
Deposit Agreement shall survive the deposit of Shares and delivery of American Depositary Shares. 
  

	6.	 FILING PROOFS, CERTIFICATES, AND OTHER INFORMATION. 

Any person presenting Shares for deposit or any Owner or Holder may be required from time to time to file with the Depositary or the Custodian
such proof of citizenship or residence, exchange control approval, or such information relating to the registration on the books of the Company or the Foreign Registrar, if applicable, to execute such certificates and to make such representations
and warranties, as the Depositary may deem necessary or proper. The Depositary may withhold the delivery or registration of transfer of any American Depositary Shares, the distribution of any dividend or other distribution or of the proceeds thereof
or the delivery of any Deposited Securities until that proof or other information is filed or those certificates are executed or those representations and warranties are made. As conditions of accepting Shares for transfer or deposit, the Depositary
may require (i) any certification required by the Depositary or the Custodian in accordance with the provisions of the Deposit Agreement, (ii) a written order directing the Depositary to deliver to, or upon the written order of, the person
or persons stated in that order, the number of American Depositary Shares representing those Deposited Shares, (iii) evidence satisfactory to the Depositary that those Shares have been re-registered in
the books of the Company or the Foreign Registrar in the name of the Depositary, a Custodian or a nominee of the Depositary or a Custodian, (iv) evidence satisfactory to the Depositary that any necessary approval has been granted by any
governmental body in each applicable jurisdiction and (v) an agreement or assignment, or other instrument satisfactory to the Depositary, that provides for the prompt transfer to the Custodian of any dividend, or right to subscribe for
additional Shares or to receive other property, that any person in whose name those Shares are or have been recorded may thereafter receive upon or in respect of those Shares, or, in lieu thereof, such agreement of indemnity or other agreement as
shall be satisfactory to the Depositary. 
  

  
 A-5 

	7.	 CHARGES OF DEPOSITARY. 

The following charges shall be incurred by any party depositing or withdrawing Shares or by any party surrendering American Depositary Shares
or to whom American Depositary Shares are issued (including, without limitation, issuance pursuant to a stock dividend or stock split declared by the Company or an exchange of stock regarding the American Depositary Shares or Deposited Securities or
a delivery of American Depositary Shares pursuant to Section 4.3 of the Deposit Agreement), or by Owners, as applicable: (1) taxes and other governmental charges, (2) such registration fees as may from time to time be in effect for
the registration of transfers of Shares generally on the Share register of the Company or Foreign Registrar and applicable to transfers of Shares to or from the name of the Depositary or its nominee or the Custodian or its nominee on the making of
deposits or withdrawals hereunder, (3) such cable (including SWIFT) and facsimile transmission fees and expenses as are expressly provided in the Deposit Agreement, (4) such expenses as are incurred by the Depositary in the conversion of
foreign currency pursuant to Section 4.5 of the Deposit Agreement, (5) a fee of $5.00 or less per 100 American Depositary Shares (or portion thereof) for the delivery of American Depositary Shares pursuant to Section 2.3, 4.3 or 4.4
of the Deposit Agreement and the surrender of American Depositary Shares pursuant to Section 2.5 or 6.2 of the Deposit Agreement, (6) a fee of $.05 or less per American Depositary Share (or portion thereof) for any cash distribution made
pursuant to the Deposit Agreement, including, but not limited to Sections 4.1 through 4.4 and 4.8 of the Deposit Agreement, (7) a fee for the distribution of securities pursuant to Section 4.2 of the Deposit Agreement or of rights pursuant
to Section 4.4 of that Agreement (where the Depositary will not exercise or sell those rights on behalf of Owners), such fee being in an amount equal to the fee for the execution and delivery of American Depositary Shares referred to above
which would have been charged as a result of the deposit of such securities under the Deposit Agreement (for purposes of this item 7 treating all such securities as if they were Shares) but which securities are instead distributed by the Depositary
to Owners, (8) in addition to any fee charged under item 6, a fee of $.05 or less per American Depositary Share (or portion thereof) per annum for depositary services, which will be payable as provided in item 9 below, and (9) any other
charges payable by the Depositary or the Custodian, any of the Depositary’s or Custodian’s agents or the agents of the Depositary’s or Custodian’s agents, in connection with the servicing of Shares or other Deposited Securities
(which charges shall be assessed against Owners as of the date or dates set by the Depositary in accordance with Section 4.6 of the Deposit Agreement and shall be payable at the sole discretion of the Depositary by billing those Owners for
those charges or by deducting those charges from one or more cash dividends or other cash distributions). 

  
 A-6 

 The Depositary may collect any of its fees by deduction from any cash distribution payable,
or by selling a portion of any securities to be distributed, to Owners that are obligated to pay those fees. 
 The Depositary may own and
deal in any class of securities of the Company and its affiliates and in American Depositary Shares. 
 From time to time, the Depositary
may make payments to the Company to reimburse the Company for costs and expenses generally arising out of establishment and maintenance of the American Depositary Shares program, waive fees and expenses for services provided by the Depositary or
share revenue from the fees collected from Owners or Holders. In performing its duties under the Deposit Agreement, the Depositary may use brokers, dealers, foreign currency dealers or other service providers that are owned by or affiliated with the
Depositary and that may earn or share fees, spreads or commissions. 
  

	8.	 DISCLOSURE OF INTERESTS. 

When required in order to comply with applicable laws and regulations, the rules and requirements of the Nasdaq Stock Market LLC or any other
stock exchange on which the Shares or the American Depositary Shares are registered or the articles of association or similar document of the Company, the Company may from time to time request each Owner and Holder to provide to the
Depositary information relating to: (a) the capacity in which it holds American Depositary Shares, (b) the identity of any Holders or other persons or entities then or previously interested in those American Depositary
Shares and the nature of those interests and (c) any other matter where disclosure of such matter is required for that compliance. Each Owner and Holder agrees to provide all information known to it in response to a request made
pursuant to Section 3.4 of the Deposit Agreement. Each Holder consents to the disclosure by the Depositary, the Owner or other Holder through which it holds American Depositary Shares, directly or indirectly, of all information
responsive to a request made pursuant to that Section relating to that Holder that is known to that Owner or other Holder.
  

	9.	 TITLE TO AMERICAN DEPOSITARY SHARES. 

It is a condition of the American Depositary Shares, and every successive Owner and Holder of American Depositary Shares, by accepting or
holding the same, consents and agrees that American Depositary Shares evidenced by a Receipt, when the Receipt is properly endorsed or accompanied by proper instruments of transfer, shall be transferable as certificated registered securities under
the laws of the State of New York, and that American Depositary Shares not evidenced by Receipts shall be transferable as uncertificated registered securities under the laws of the State of New York. The Depositary and the Company, notwithstanding
any notice to the contrary, may treat the Owner of American Depositary Shares as the absolute owner thereof for the purpose of determining the person entitled to distribution of dividends or other distributions or to any notice provided for in the
Deposit Agreement and for all other purposes, and neither the Depositary nor the Company shall have any obligation or be subject to any liability under the Deposit Agreement to any Holder of American Depositary Shares, but only to the Owner. 

 

  
 A-7 

	10.	 VALIDITY OF RECEIPT. 

This Receipt shall not be entitled to any benefits under the Deposit Agreement or be valid or obligatory for any purpose, unless this Receipt
shall have been (i) executed by the Depositary by the manual signature of a duly authorized officer of the Depositary or (ii) executed by the facsimile signature of a duly authorized officer of the Depositary and countersigned by the
manual signature of a duly authorized signatory of the Depositary or the Registrar or a co-registrar. 
  

	11.	 REPORTS; INSPECTION OF TRANSFER BOOKS. 

The Company is subject to the periodic reporting requirements of the Securities Exchange Act of 1934 and, accordingly, files certain reports
with the Securities and Exchange Commission. Those reports will be available for inspection and copying through the Commission’s EDGAR system or at public reference facilities maintained by the Commission in Washington, D.C. 

The Depositary will make available for inspection by Owners at its Office any reports, notices and other communications, including any proxy
soliciting material, received from the Company which are both (a) received by the Depositary as the holder of the Deposited Securities and (b) made generally available to the holders of those Deposited Securities by the Company. The
Company shall furnish reports and communications, including any proxy soliciting material to which Section 4.9 of the Deposit Agreement applies, to the Depositary in English, to the extent such materials are required to be translated into
English pursuant to any regulations of the Commission. 
 The Depositary will maintain a register of American Depositary Shares and
transfers of American Depositary Shares, which shall be open for inspection by the Owners at the Depositary’s Office during regular business hours, but only for the purpose of communicating with Owners regarding the business of the Company or a
matter related to this Deposit Agreement or the American Depositary Shares. 
  

	12.	 DIVIDENDS AND DISTRIBUTIONS. 

Whenever the Depositary receives any cash dividend or other cash distribution on Deposited Securities, the Depositary will, if at the time of
receipt thereof any amounts received in a foreign currency can in the judgment of the Depositary be converted on a reasonable basis into Dollars transferable to the United States, and subject to the Deposit Agreement, convert that dividend or other
cash distribution into Dollars and distribute the amount thus received (net of the fees and expenses of the Depositary as provided in Article 7 hereof and Section 5.9 of the Deposit Agreement) to the Owners entitled thereto;

  
 A-8 

 
provided, however, that if the Custodian or the Depositary is required to withhold and does withhold from that cash dividend or other cash distribution an amount on account of taxes
or other governmental charges, the amount distributed to the Owners of the American Depositary Shares representing those Deposited Securities shall be reduced accordingly. 

If a cash distribution would represent a return of all or substantially all the value of the Deposited Securities underlying American
Depositary Shares, the Depositary may: 
 (i) require payment of or deduct the fee for surrender of American Depositary Shares (whether or
not it is also requiring surrender of American Depositary Shares) as a condition of making that cash distribution; or 
 (ii) sell all
Deposited Securities other than the subject cash distribution and add any net cash proceeds of that sale to the cash distribution, call for surrender of all those American Depositary Shares and require that surrender as a condition of making that
cash distribution. 
 If the Depositary acts under this paragraph, that action shall also be a Termination Option Event. 

Subject to the provisions of Section 4.11 and 5.9 of the Deposit Agreement, whenever the Depositary receives any distribution other than
a distribution described in Section 4.1, 4.3 or 4.4 of the Deposit Agreement on Deposited Securities (but not in exchange for or in conversion or in lieu of Deposited Securities), the Depositary will cause the securities or property received by
it to be distributed to the Owners entitled thereto, after deduction or upon payment of any fees and expenses of the Depositary and any taxes or other governmental charges, in any manner that the Depositary deems equitable and practicable for
accomplishing that distribution (which may be a distribution of depositary shares representing the securities received); provided, however, that if in the opinion of the Depositary such distribution cannot be made proportionately among
the Owners entitled thereto, or if for any other reason the Depositary, after consultation with the Company to the extent practicable, deems such distribution not to be lawful and feasible, the Depositary may adopt such other method as it may deem
equitable and practicable for the purpose of effecting such distribution, including, but not limited to, the public or private sale of the securities or property thus received, or any part thereof, and distribution of the net proceeds of any such
sale (net of the fees and expenses of the Depositary as provided in Article 7 hereof and Section 5.9 of the Deposit Agreement) to the Owners entitled thereto all in the manner and subject to the conditions set forth in Section 4.1 of
the Deposit Agreement. The Depositary may withhold any distribution of securities under Section 4.2 of the Deposit Agreement if it has not received satisfactory assurances from the Company that the distribution does not require registration
under the Securities Act of 1933. The Depositary may sell, by public or private sale, an amount of securities or other property it would otherwise distribute under this Article that is sufficient to pay its fees and expenses in respect of that
distribution. 

  
 A-9 

 If a distribution to be made under Section 4.2 of the Deposit Agreement would represent
a return of all or substantially all the value of the Deposited Securities underlying American Depositary Shares, the Depositary may: 
 (i)
require payment of or deduct the fee for surrender of American Depositary Shares (whether or not it is also requiring surrender of American Depositary Shares) as a condition of making that distribution; or 

(ii) sell all Deposited Securities other than the subject distribution and add any net cash proceeds of that sale to the distribution, call
for surrender of all those American Depositary Shares and require that surrender as a condition of making that distribution. 
 If the Depositary acts under
this paragraph, that action shall also be a Termination Option Event. 
 Whenever the Depositary receives any distribution consisting
of a dividend in, or free distribution of, Shares, the Depositary may deliver to the Owners entitled thereto, an aggregate number of American Depositary Shares representing the amount of Shares received as that dividend or free distribution, subject
to the terms and conditions of the Deposit Agreement with respect to the deposit of Shares and issuance of American Depositary Shares, including the withholding of any tax or other governmental charge as provided in Section 4.11 of the Deposit
Agreement and the payment of the fees and expenses of the Depositary as provided in Article 7 hereof and Section 5.9 of the Deposit Agreement (and the Depositary may sell, by public or private sale, an amount of Shares received (or American
Depositary Shares representing those Shares) sufficient to pay its fees and expenses in respect of that distribution). In lieu of delivering fractional American Depositary Shares, the Depositary may sell the amount of Shares represented by the
aggregate of those fractions (or American Depositary Shares representing those Shares) and distribute the net proceeds, all in the manner and subject to the conditions described in Section 4.1of the Deposit Agreement. If and to the extent that
additional American Depositary Shares are not delivered and Shares or American Depositary Shares are not sold, each American Depositary Share shall thenceforth also represent the additional Shares distributed on the Deposited Securities represented
thereby. 
 If the Company declares a distribution in which holders of Deposited Securities have a right to elect whether to receive cash,
Shares or other securities or a combination of those things, or a right to elect to have a distribution sold on their behalf, the Depositary may, after consultation with the Company, make that right of election available for exercise by Owners in
any manner the Depositary considers to be lawful and practical. As a condition of making a distribution election right available to Owners, the Depositary may require satisfactory assurances from the Company that doing so does not require
registration of any securities under the Securities Act of 1933 that has not been effected. 

  
 A-10 

 If the Depositary determines that any distribution received or to be made by the Depositary
(including Shares and rights to subscribe therefor) is subject to any tax or other governmental charge that the Depositary is obligated to withhold, the Depositary may sell, by public or private sale, all or a portion of the distributed property
(including Shares and rights to subscribe therefor) in the amounts and manner the Depositary deems necessary and practicable to pay those taxes or charges, and the Depositary shall distribute the net proceeds of that sale, after deduction of those
taxes or charges, to the Owners entitled thereto in proportion to the number of American Depositary Shares held by them respectively. 

Each Owner and Holder agrees to indemnify the Company, the Depositary, the Custodian and their respective directors, employees, agents and
affiliates for, and hold each of them harmless against, any claim by any governmental authority with respect to taxes, additions to tax, penalties or interest arising out of any refund of taxes, reduced withholding at source or other tax benefit
received by it. Services for Owners and Holders that may permit them to obtain reduced rates of tax withholding at source or reclaim excess tax withheld, and the fees and costs associated with using services of that kind, are not provided under, and
are outside the scope of, the Deposit Agreement. 
  

	13.	 RIGHTS. 

(a) If rights are granted to the Depositary in respect of deposited Shares to purchase additional Shares or other securities, the Company and
the Depositary shall endeavor to consult as to the actions, if any, the Depositary should take in connection with that grant of rights. The Depositary may, to the extent deemed by it to be lawful and practical (i) if requested in writing by the
Company, grant to all or certain Owners rights to instruct the Depositary to purchase the securities to which the rights relate and deliver those securities or American Depositary Shares representing those securities to Owners, (ii) if
requested in writing by the Company, deliver the rights to or to the order of certain Owners, or (iii) sell the rights to the extent practicable and distribute the net proceeds of that sale to Owners entitled to those proceeds. To the extent
rights are not exercised, delivered or disposed of under (i), (ii) or (iii) above, the Depositary shall permit the rights to lapse unexercised. 

(b) If the Depositary will act under (a)(i) above, the Company and the Depositary will enter into a separate agreement setting forth the
conditions and procedures applicable to the particular offering. Upon instruction from an applicable Owner in the form the Depositary specified and upon payment by that Owner to the Depositary of an amount equal to the purchase price of the
securities to be received upon the exercise of the rights, the Depositary shall, on behalf of that Owner, exercise the rights and purchase the securities. The purchased securities shall be delivered to, or as instructed by, the Depositary. The
Depositary shall (i) deposit the purchased Shares under the Deposit Agreement and deliver American Depositary Shares representing those Shares to that Owner or (ii) deliver or cause the purchased Shares or other securities to be delivered
to or 

  
 A-11 

 
to the order of that Owner. The Depositary will not act under (a)(i) above unless the offer and sale of the securities to which the rights relate are registered under the Securities Act of 1933
or the Depositary has received an opinion of United States counsel that is satisfactory to it to the effect that those securities may be sold and delivered to the applicable Owners without registration under the Securities Act of 1933. 

(c) If the Depositary will act under (a)(ii) above, the Company and the Depositary will enter into a separate agreement setting forth the
conditions and procedures applicable to the particular offering. Upon (i) the request of an applicable Owner to deliver the rights allocable to the American Depositary Shares of that Owner to an account specified by that Owner to which the
rights can be delivered and (ii) receipt of such documents as the Company and the Depositary agreed to require to comply with applicable law, the Depositary will deliver those rights as requested by that Owner. 

(d) If the Depositary will act under (a)(iii) above, the Depositary will use reasonable efforts to sell the rights in proportion to the number
of American Depositary Shares held by the applicable Owners and pay the net proceeds to the Owners otherwise entitled to the rights that were sold, upon an averaged or other practical basis without regard to any distinctions among such Owners
because of exchange restrictions or the date of delivery of any American Depositary Shares or otherwise. 
 (e) Payment or deduction of the
fees of the Depositary as provided in Section 5.9 of the Deposit Agreement and payment or deduction of the expenses of the Depositary and any applicable taxes or other governmental charges shall be conditions of any delivery of securities or
payment of cash proceeds under Section 4.4 of that Agreement. 
 (f) The Depositary shall not be responsible for any failure to
determine that it may be lawful or feasible to make rights available to or exercise rights on behalf of Owners in general or any Owner in particular, or to sell rights. 

14. CONVERSION OF FOREIGN CURRENCY. 
 Whenever
the Depositary or the Custodian receives foreign currency, by way of dividends or other distributions or the net proceeds from the sale of securities, property or rights, and if at the time of the receipt thereof the foreign currency so received can
in the judgment of the Depositary be converted on a reasonable basis into Dollars and the resulting Dollars transferred to the United States, the Depositary or one of its agents or affiliates or the Custodian shall convert or cause to be converted
by sale or in any other manner that it may determine that foreign currency into Dollars, and those Dollars shall be distributed to the Owners entitled thereto. A cash distribution may be made upon an averaged or other practicable basis without
regard to any distinctions among Owners based on exchange restrictions, the date of delivery of any American Depositary Shares or otherwise and shall be net of any expenses of conversion into Dollars incurred by the Depositary as provided in
Section 5.9 of the Deposit Agreement. 

  
 A-12 

 If a conversion of foreign currency or the repatriation or distribution of Dollars can be
effected only with the approval or license of any government or agency thereof, the Depositary may, but will not be required to, file an application for that approval or license. 

If the Depositary determines that in its judgment any foreign currency received by the Depositary or the Custodian is not convertible on a
reasonable basis into Dollars transferable to the United States, or if any approval or license of any government or agency thereof that is required for such conversion is not filed or sought by the Depositary or is not obtained within a reasonable
period as determined by the Depositary, the Depositary may distribute the foreign currency received by the Depositary to, or in its discretion may hold such foreign currency uninvested and without liability for interest thereon for the respective
accounts of, the Owners entitled to receive the same. 
 If any conversion of foreign currency, in whole or in part, cannot be effected for
distribution to some of the Owners entitled thereto, the Depositary may in its discretion make that conversion and distribution in Dollars to the extent practicable and permissible to the Owners entitled thereto and may distribute the balance of the
foreign currency received by the Depositary to, or hold that balance uninvested and without liability for interest thereon for the account of, the Owners entitled thereto. 

The Depositary may convert currency itself or through any of its affiliates, or the Custodian or the Company may convert currency and pay
Dollars to the Depositary. Where the Depositary converts currency itself or through any of its affiliates, the Depositary acts as principal for its own account and not as agent, advisor, broker or fiduciary on behalf of any other person and earns
revenue, including, without limitation, transaction spreads, that it will retain for its own account. The revenue is based on, among other things, the difference between the exchange rate assigned to the currency conversion made under the
Deposit Agreement and the rate that the Depositary or its affiliate receives when buying or selling foreign currency for its own account. The Depositary makes no representation that the exchange rate used or obtained by it or its affiliate in
any currency conversion under the Deposit Agreement will be the most favorable rate that could be obtained at the time or that the method by which that rate will be determined will be the most favorable to Owners, subject to the Depositary’s
obligations under Section 5.3 of that Agreement. The methodology used to determine exchange rates used in currency conversions made by the Depositary is available upon request. Where the Custodian converts currency, the Custodian has no
obligation to obtain the most favorable rate that could be obtained at the time or to ensure that the method by which that rate will be determined will be the most favorable to Owners, and the Depositary makes no representation that the rate is the
most favorable rate and will not be liable for any direct or indirect losses associated with the rate. In certain instances, the Depositary may receive dividends or other distributions from the Company in Dollars that represent the proceeds of
a conversion of foreign currency or translation from foreign currency at a rate that was obtained or determined by or on behalf of the Company and, in such cases, the Depositary will not engage in, or be responsible for, any foreign currency
transactions and neither it nor the Company makes any representation that the rate obtained or determined by the Company is the most favorable rate and neither it nor the Company will be liable for any direct or indirect losses associated with the
rate.

	15.	 RECORD DATES. 

Whenever a cash dividend, cash distribution or any other distribution is made on Deposited Securities or rights to purchase Shares or other
securities are issued with respect to Deposited Securities (which rights will be delivered to or exercised or sold on behalf of Owners in accordance with Section 4.4 of the Deposit Agreement) or the Depositary receives notice that a
distribution or issuance of that kind will be made, or whenever the Depositary receives notice that a meeting of holders of Shares will be held in respect of which the Company has requested the Depositary to send a notice under Section 4.7 of
the Deposit Agreement, or whenever the Depositary will assess a fee or charge against the Owners, or whenever the Depositary causes a change in the number of Shares that are represented by each American Depositary Share, or whenever the Depositary
otherwise finds it necessary or convenient, the Depositary shall fix a record date, which shall be the same as, or as near as practicable to, any corresponding record date set by the Company with respect to Shares, (a) for the determination of
the Owners (i) who shall be entitled to receive the benefit of that dividend or other distribution or those rights, (ii) who shall be entitled to give instructions for the exercise of voting rights at that meeting, (iii) who shall be
responsible for that fee or charge or (iv) for any other purpose for which the record date was set, or (b) on or after which each American Depositary Share will represent the changed number of Shares. Subject to the provisions of Sections
4.1 through 4.5 of the Deposit Agreement and to the other terms and conditions of the Deposit Agreement, the Owners on a record date fixed by the Depositary shall be entitled to receive the amount distributable by the Depositary with respect to that
dividend or other distribution or those rights or the net proceeds of sale thereof in proportion to the number of American Depositary Shares held by them respectively, to give voting instructions or to act in respect of the other matter for which
that record date was fixed, or be responsible for that fee or charge, as the case may be. 
  

	16.	 VOTING OF DEPOSITED SHARES. 

(a) Upon receipt of notice of any meeting of holders of Shares at which holders of Shares will be entitled to vote, if requested in writing
by the Company, the Depositary shall, as soon as practicable thereafter, Disseminate to the Owners a notice, the form of which shall be in the sole discretion of the Depositary, that shall contain (i) the information contained in the
notice of meeting received by the Depositary, (ii) a statement that the Owners as of the close of business on a specified record date will be entitled, subject to any applicable provision of the laws of England and Wales and of the articles of
association or similar documents of the Company, to instruct the Depositary as to the exercise of the voting rights pertaining to the amount of Shares represented by their respective American Depositary Shares (iii) a statement as to the manner
in which those 

  
 A-14 

 
instructions may be given, including an express indication that instructions may be deemed given in accordance with the last sentence of paragraph (b) below, if no instruction is received,
to the Depositary to give a discretionary proxy to a person designated by the Company and (iv) the last date on which the Depositary will accept instructions (the “Instruction Cutoff Date”). 

(b) Upon the written request of an Owner of American Depositary Shares, as of the date of the request or, if a record date was specified by
the Depositary, as of that record date, received on or before any Instruction Cutoff Date established by the Depositary, the Depositary may, and if the Depositary sent a notice under the preceding paragraph shall, endeavor, in so far
as practicable, to vote or cause to be voted the amount of deposited Shares represented by those American Depositary Shares in accordance with the instructions set forth in that request. The Depositary shall not vote or attempt to exercise the right
to vote that attaches to the deposited Shares other than in accordance with instructions given by Owners and received by the Depositary or as provided in the following sentence. If 

(i) the Company instructed the Depositary to Disseminate a notice under paragraph (a) above and complied with paragraph (d) below,

 (ii) no instructions are received by the Depositary from an Owner with respect to a matter and an amount of American Depositary Shares of
that Owner on or before the Instruction Cutoff Date and 
 (iii) the Depositary has received from the Company, by the business day following
the Instruction Cutoff Date, a written confirmation that, as of the Instruction Cutoff Date, (x) the Company wishes a proxy to be given under this sentence, (y) the Company reasonably does not know of any substantial opposition to the
matters and (z) the matters are not materially adverse to the interests of shareholders, 
 then, the Depositary shall deem that Owner to have
instructed the Depositary to give a discretionary proxy to a person designated by the Company with respect to that matter and the amount of deposited Shares represented by that amount of American Depositary Shares and the Depositary shall give a
discretionary proxy to a person designated by the Company to vote that amount of deposited Shares as to that matter. 
 (c) There can be no
assurance that Owners generally or any Owner in particular will receive the notice described in paragraph (a) above in time to enable Owners to give instructions to the Depositary prior to the Instruction Cutoff Date. 

(d) If the Company will request the Depositary to Disseminate a notice under paragraph (a) above, the Company shall give the
Depositary notice of the meeting, details concerning the matters to be voted upon and copies of materials to be made available to holders of Shares in connection with the meeting not less than 45 days prior to the meeting date. 

Notwithstanding anything in Section 4.7 of the Deposit Agreement to the contrary, the Depositary and the Company may modify, amend or adopt
additional procedures relating to voting of deposited Shares from time to time as they determine may be necessary to comply with applicable laws and regulations. 

  
 A-15 

	17.	 TENDER AND EXCHANGE OFFERS; REDEMPTION, REPLACEMENT OR CANCELLATION OF DEPOSITED SECURITIES.

 (a) The Depositary shall not tender any Deposited Securities in response to any voluntary cash tender offer, exchange
offer or similar offer made to holders of Deposited Securities (a “Voluntary Offer”), except when instructed in writing to do so by an Owner surrendering American Depositary Shares and subject to any conditions or procedures the
Depositary may require. 
 (b) If the Depositary receives a written notice that Deposited Securities have been redeemed for cash or
otherwise purchased for cash in a transaction that is mandatory and binding on the Depositary as a holder of those Deposited Securities (a “Redemption”), the Depositary, at the expense of the Company, shall (i) if required,
surrender Deposited Securities that have been redeemed to the issuer of those securities or its agent on the redemption date, (ii) Disseminate a notice to Owners (A) notifying them of that Redemption, (B) calling for surrender of a
corresponding number of American Depositary Shares and (C) notifying them that the called American Depositary Shares have been converted into a right only to receive the money received by the Depositary upon that Redemption and those net
proceeds shall be the Deposited Securities to which Owners of those converted American Depositary Shares shall be entitled upon surrenders of those American Depositary Shares in accordance with Section 2.5 or 6.2 of the Deposit Agreement and
(iii) distribute the money received upon that Redemption to the Owners entitled to it upon surrender by them of called American Depositary Shares in accordance with Section 2.5 of that Agreement (and, for the avoidance of doubt, Owners
shall not be entitled to receive that money under Section 4.1 of that Agreement). If the Redemption affects less than all the Deposited Securities, the Depositary shall call for surrender a corresponding portion of the outstanding American
Depositary Shares and only those American Depositary Shares will automatically be converted into a right to receive the net proceeds of the Redemption. The Depositary shall allocate the American Depositary Shares converted under the preceding
sentence among the Owners pro-rata to their respective holdings of American Depositary Shares immediately prior to the Redemption, except that the allocations may be adjusted so that no fraction of a
converted American Depositary Share is allocated to any Owner. A Redemption of all or substantially all of the Deposited Securities shall be a Termination Option Event. 

(c) If the Depositary is notified of or there occurs any change in nominal value or any subdivision, combination or any other reclassification
of the Deposited Securities or any recapitalization, reorganization, sale of assets substantially as an entirety, merger or consolidation affecting the issuer of the Deposited Securities or to which it is a party that is mandatory and binding on the
Depositary as a holder of Deposited Securities and, as a result, securities or other property have been or will be delivered in exchange, conversion, replacement or in lieu of, Deposited Securities (a “Replacement”), the Depositary
shall, if required, surrender the old Deposited Securities affected by that Replacement of Shares and hold, as new Deposited Securities under the Deposit Agreement, the new securities or 

  
 A-16 

 
other property delivered to it in that Replacement. However, the Depositary may elect to sell those new Deposited Securities if in the opinion of the Depositary, after consultation with
the Company to the extent practicable, it is not lawful or not practical for it to hold those new Deposited Securities under the Deposit Agreement because those new Deposited Securities may not be distributed to Owners without registration under the
Securities Act of 1933 or for any other reason, at public or private sale, at such places and on such terms as it deems proper and proceed as if those new Deposited Securities had been Redeemed under paragraph (b) above. A Replacement shall be
a Termination Option Event. 
 (d) In the case of a Replacement where the new Deposited Securities will continue to be held under the
Deposit Agreement, the Depositary may, after consultation with the Company to the extent practicable, call for the surrender of outstanding Receipts to be exchanged for new Receipts specifically describing the new Deposited Securities and the number
of those new Deposited Securities represented by each American Depositary Share. If the number of Shares represented by each American Depositary Share decreases as a result of a Replacement, the Depositary may call for surrender of the American
Depositary Shares to be exchanged on a mandatory basis for a lesser number of American Depositary Shares and may sell American Depositary Shares to the extent necessary to avoid distributing fractions of American Depositary Shares in that exchange
and distribute the net proceeds of that sale to the Owners entitled to them. 
 (e) If there are no Deposited Securities with respect to
American Depositary Shares, including if the Deposited Securities are cancelled, or the Deposited Securities with respect to American Depositary Shares become apparently worthless, the Depositary may call for surrender of those American Depositary
Shares or may cancel those American Depositary Shares, upon notice to Owners, and that condition shall be a Termination Option Event. 
  

	18.	 LIABILITY OF THE COMPANY AND DEPOSITARY. 

Neither the Depositary nor the Company nor any of their respective directors, employees, agents or affiliates shall incur any liability to any
Owner or Holder: 
 (i) if by reason of (A) any provision of any present or future law or regulation or other act of the government of
the United States, any State of the United States or any other state or jurisdiction, or of any governmental or regulatory authority or stock exchange; (B) (in the case of the Depositary only) any provision, present or future, of the articles of
association or similar document of the Company, or by reason of any provision of any securities issued or distributed by the Company, or any offering or distribution thereof; or (C) any event or circumstance, whether natural or caused by a
person or persons, that is beyond the ability of the Depositary or the Company, as the case may be, to prevent or counteract by reasonable care or effort (including, but not limited to earthquakes, floods, severe storms, fires, explosions, war,
terrorism, civil unrest, labor disputes, criminal acts or outbreaks of infectious disease; interruptions or malfunctions of utility services, Internet or other communications lines or systems; unauthorized access to or attacks on computer

  
 A-17 

 
systems or websites; or other failures or malfunctions of computer hardware or software or other systems or equipment), the Depositary or the Company is, directly or indirectly, prevented from,
forbidden to or delayed in, or could be subject to any civil or criminal penalty on account of doing or performing and therefore does not do or perform, any act or thing that, by the terms of the Deposit Agreement or the Deposited Securities, it is
provided shall be done or performed; 
 (ii) for any exercise of, or failure to exercise, any discretion provided for in the Deposit
Agreement (including any determination by the Depositary to take, or not take, any action that the Deposit Agreement provides the Depositary may take); 

(iii) for the inability of any Owner or Holder to benefit from any distribution, offering, right or other benefit that is made available to
holders of Deposited Securities but is not, under the terms of the Deposit Agreement, made available to Owners or Holders; or 
 (iv) for
any special, consequential or punitive damages for any breach of the terms of the Deposit Agreement. 
 Where, by the terms of a
distribution to which Section 4.1, 4.2 or 4.3 of the Deposit Agreement applies, or an offering to which Section 4.4 of that Agreement applies, or for any other reason, that distribution or offering may not be made available to Owners, and
the Depositary may not dispose of that distribution or offering on behalf of Owners and make the net proceeds available to Owners, then the Depositary shall not make that distribution or offering available to Owners, and shall allow any rights, if
applicable, to lapse. 
 Neither the Company nor the Depositary assumes any obligation or shall be subject to any liability under the
Deposit Agreement to Owners or Holders, except that they agree to perform their obligations specifically set forth in the Deposit Agreement without negligence or bad faith. The Depositary shall not be a fiduciary or have any fiduciary duty to Owners
or Holders. The Depositary shall not be subject to any liability with respect to the validity or worth of the Deposited Securities. Neither the Depositary nor the Company shall be under any obligation to appear in, prosecute or defend any action,
suit, or other proceeding in respect of any Deposited Securities or in respect of the American Depositary Shares, on behalf of any Owner or Holder or other person. Neither the Depositary nor the Company shall be liable for any action or non-action by it in reliance upon the advice of or information from legal counsel, accountants, any person presenting Shares for deposit, any Owner or Holder, or any other person believed by it in good faith to be
competent to give such advice or information. Each of the Depositary and the Company may rely, and shall be protected in relying upon, any written notice, request, direction or other document believed by it to be genuine and to have been signed or
presented by the proper party or parties. The Depositary shall not be liable for any acts or omissions made by a successor depositary whether in connection with a previous act or omission of the Depositary or in connection with a matter arising
wholly after the removal or resignation of the Depositary, provided that in connection with the issue out of which such potential liability arises, the 

  
 A-18 

 
Depositary performed its obligations without negligence or bad faith while it acted as Depositary. The Depositary shall not be liable for the acts or omissions of any securities depository,
clearing agency or settlement system in connection with or arising out of book-entry settlement of American Depositary Shares or Deposited Securities or otherwise. In the absence of bad faith on its part, the Depositary shall not be responsible for
any failure to carry out any instructions to vote any of the Deposited Securities or for the manner in which any such vote is cast or the effect of any such vote. The Depositary shall have no duty to make any determination or provide any information
as to the tax status of the Company or any liability for any tax consequences that may be incurred by Owners or Holders as a result of owning or holding American Depositary Shares. The Depositary shall not be liable for the inability or failure of
an Owner or Holder to obtain the benefit of a foreign tax credit, reduced rate of withholding or refund of amounts withheld in respect of tax or any other tax benefit. No disclaimer of liability under the United States federal securities laws is
intended by any provision of the Deposit Agreement. 
  

	19.	 RESIGNATION AND REMOVAL OF THE DEPOSITARY; APPOINTMENT OF SUCCESSOR CUSTODIAN. 

The Depositary may at any time resign as Depositary under the Deposit Agreement by written notice of its election so to do delivered to the
Company, to become effective upon the appointment of a successor depositary and its acceptance of such appointment as provided in the Deposit Agreement. The Depositary may at any time be removed by the Company by 90 days’ prior written notice
of that removal, to become effective upon the later of (i) the 90th day after delivery of the notice to the Depositary and (ii) the appointment of a successor depositary and its
acceptance of its appointment as provided in the Deposit Agreement. The Depositary in its discretion may at any time appoint a substitute or additional custodian or custodians. 

 

	20.	 AMENDMENT. 

The form of the Receipts and any provisions of the Deposit Agreement may at any time and from time to time be amended by agreement between the
Company and the Depositary without the consent of Owners or Holders in any respect which they may deem necessary or desirable. Any amendment that would impose or increase any fees or charges (other than taxes and other governmental charges,
registration fees, cable (including SWIFT) or facsimile transmission costs, delivery costs or other such expenses), or that would otherwise prejudice any substantial existing right of Owners, shall, however, not become effective as to outstanding
American Depositary Shares until the expiration of 30 days after notice of that amendment has been Disseminated to the Owners of outstanding American Depositary Shares. Every Owner and Holder, at the time any amendment so becomes effective, shall be
deemed, by continuing to hold American Depositary Shares or any interest therein, to consent and agree to that amendment and to be bound by the Deposit Agreement as amended thereby. Upon the effectiveness of an amendment to the form of Receipt,
including a change in the number of Shares represented by each American 

  
 A-19 

 
Depositary Share, the Depositary may call for surrender of Receipts to be replaced with new Receipts in the amended form or call for surrender of American Depositary Shares to effect that change
of ratio. In no event shall any amendment impair the right of the Owner to surrender American Depositary Shares and receive delivery of the Deposited Securities represented thereby, except in order to comply with mandatory provisions of applicable
law. 
  

	21.	 TERMINATION OF DEPOSIT AGREEMENT. 

(a) The Company may initiate termination of the Deposit Agreement by notice to the Depositary. The Depositary may initiate termination of the
Deposit Agreement if (i) at any time 60 days shall have expired after the Depositary delivered to the Company a written resignation notice and a successor depositary has not been appointed and accepted its appointment as provided in
Section 5.4 of that Agreement or (ii) a Termination Option Event has occurred. If termination of the Deposit Agreement is initiated, the Depositary shall Disseminate a notice of termination to the Owners of all American Depositary Shares
then outstanding setting a date for termination (the “Termination Date”), which shall be at least 90 days after the date of that notice, and the Deposit Agreement shall terminate on that Termination Date. 

(b) After the Termination Date, the Company shall be discharged from all obligations under the Deposit Agreement except for its obligations to
the Depositary under Sections 5.8 and 5.9 of that Agreement. 
 (c) At any time after the Termination Date, the Depositary may sell the
Deposited Securities then held under the Deposit Agreement and may thereafter hold uninvested the net proceeds of any such sale, together with any other cash then held by it hereunder, unsegregated and without liability for interest, for the pro
rata benefit of the Owners of American Depositary Shares that remain outstanding, and those Owners will be general creditors of the Depositary with respect to those net proceeds and that other cash. After making that sale, the Depositary shall be
discharged from all obligations under the Deposit Agreement, except (i) to account for the net proceeds and other cash (after deducting, in each case, the fee of the Depositary for the surrender of American Depositary Shares, any expenses for
the account of the Owner of such American Depositary Shares in accordance with the terms and conditions of the Deposit Agreement and any applicable taxes or governmental charges) and (ii) for its obligations under Section 5.8 of that
Agreement and (iii) to act as provided in paragraph (d) below. 
 (d) After the Termination Date, the Depositary shall continue to
receive dividends and other distributions pertaining to Deposited Securities (that have not been sold), may sell rights and other property as provided in the Deposit Agreement and shall deliver Deposited Securities (or sale proceeds) upon surrender
of American Depositary Shares (after payment or upon deduction, in each case, of the fee of the Depositary for the surrender of American Depositary Shares, any expenses for the account of the Owner of those American Depositary Shares in accordance
with the terms and conditions of the 

  
 A-20 

 
Deposit Agreement and any applicable taxes or governmental charges). After the Termination Date, the Depositary shall not accept deposits of Shares or deliver American Depositary Shares. After
the Termination Date, (i) the Depositary may refuse to accept surrenders of American Depositary Shares for the purpose of withdrawal of Deposited Securities (that have not been sold) or reverse previously accepted surrenders of that kind that
have not settled if in its judgment the requested withdrawal would interfere with its efforts to sell the Deposited Securities, (ii) the Depositary will not be required to deliver cash proceeds of the sale of Deposited Securities until all
Deposited Securities have been sold and (iii) the Depositary may discontinue the registration of transfers of American Depositary Shares and suspend the distribution of dividends and other distributions on Deposited Securities to the Owners and
need not give any further notices or perform any further acts under the Deposit Agreement except as provided in Section 6.2 of that Agreement. 
  

	22.	 DTC DIRECT REGISTRATION SYSTEM AND PROFILE MODIFICATION SYSTEM. 

(a) Notwithstanding the provisions of Section 2.4 of the Deposit Agreement, the parties acknowledge that DTC’s Direct Registration
System (“DRS”) and Profile Modification System (“Profile”) apply to the American Depositary Shares upon acceptance thereof to DRS by DTC. DRS is the system administered by DTC that facilitates interchange between
registered holding of uncertificated securities and holding of security entitlements in those securities through DTC and a DTC participant. Profile is a required feature of DRS that allows a DTC participant, claiming to act on behalf of an Owner of
American Depositary Shares, to direct the Depositary to register a transfer of those American Depositary Shares to DTC or its nominee and to deliver those American Depositary Shares to the DTC account of that DTC participant without receipt by the
Depositary of prior authorization from the Owner to register that transfer. 
 (b) In connection with DRS/Profile, the parties acknowledge
that the Depositary will not determine whether the DTC participant that is claiming to be acting on behalf of an Owner in requesting registration of transfer and delivery as described in paragraph (a) above has the actual authority to act on
behalf of that Owner (notwithstanding any requirements under the Uniform Commercial Code). For the avoidance of doubt, the provisions of Sections 5.3 and 5.8 of the Deposit Agreement apply to the matters arising from the use of the DRS/Profile. The
parties agree that the Depositary’s reliance on and compliance with instructions received by the Depositary through the DRS/Profile system and otherwise in accordance with the Deposit Agreement, shall not constitute negligence or bad faith on
the part of the Depositary. 
  

	23.	 APPOINTMENT OF AGENT FOR SERVICE OF PROCESS; SUBMISSION TO JURISDICTION; JURY TRIAL WAIVER; WAIVER OF
IMMUNITIES. 

 The Company has (i) appointed ______________________________________ as the Company’s authorized
agent in the United States upon which process may be served in 

  
 A-21 

 
any suit or proceeding arising out of or relating to the Shares or Deposited Securities, the American Depositary Shares, the Receipts or this Agreement, (ii) consented and submitted to the
jurisdiction of any state or federal court in the State of New York in which any such suit or proceeding may be instituted, and (iii) agreed that service of process upon said authorized agent shall be deemed in every respect effective service
of process upon the Company in any such suit or proceeding. 
 EACH PARTY TO THE DEPOSIT AGREEMENT (INCLUDING, FOR AVOIDANCE OF DOUBT, EACH
OWNER AND HOLDER) THEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY SUIT, ACTION OR PROCEEDING AGAINST THE COMPANY AND/OR THE DEPOSITARY DIRECTLY OR INDIRECTLY ARISING OUT
OF OR RELATING TO THE SHARES OR OTHER DEPOSITED SECURITIES, THE AMERICAN DEPOSITARY SHARES OR THE RECEIPTS, THE DEPOSIT AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREIN OR THEREIN, OR THE BREACH HEREOF OR THEREOF, INCLUDING, WITHOUT LIMITATION, ANY
QUESTION REGARDING EXISTENCE, VALIDITY OR TERMINATION (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). 
 To the extent that the
Company or any of its properties, assets or revenues may have or hereafter become entitled to, or have attributed to it, any right of immunity, on the grounds of sovereignty or otherwise, from any legal action, suit or proceeding, from the giving of
any relief in any respect thereof, from setoff or counterclaim, from the jurisdiction of any court, from service of process, from attachment upon or prior to judgment, from attachment in aid of execution or judgment, or other legal process or
proceeding for the giving of any relief or for the enforcement of any judgment, in any jurisdiction in which proceedings may at any time be commenced, with respect to its obligations, liabilities or any other matter under or arising out of or in
connection with the Shares or Deposited Securities, the American Depositary Shares, the Receipts or the Deposit Agreement, the Company, to the fullest extent permitted by law, hereby irrevocably and unconditionally waives, and agrees not to plead or
claim, any such immunity and consents to such relief and enforcement. 

  
 A-22EX-10.1

 Exhibit 10.1 
  

 
 ACHILLES TX LIMITED 

OMNIBUS PLAN 
 SECTION 1. PURPOSE

 The purpose of this Omnibus Plan is to maximise the ability of Achilles TX Limited (the ‘Company’) to attract, motivate and retain
Service Providers who make, or will make, valuable contributions to the Company, by providing these Service Providers with equity ownership opportunities through Share Plans. 

This Omnibus Plan is a preface to the various Share Plans offered by the Company. 

SECTION 2. ADMINISTRATION  
 The Omnibus Plan is
controlled by the Remuneration Committee. The Remuneration Committee has the authority, under its Terms of Reference, to review the design of all Share Plans for approval by the Board and shareholders, to determine each year whether awards will be
made and, if so, the overall amount of such awards, the individual awards to each eligible member of any Group Company and the performance targets to be used. 

The Remuneration Committee has authority to take all actions and make all determinations pertaining to the Share Plans, to interpret the Share Plans and
related agreements and to amend, adopt and repeal Share Plans as it deems advisable. 
 The Remuneration Committee may address defects and ambiguities and
reconcile inconsistencies as it deems necessary to be able to administer the Share Plans and Awards. The Remuneration Committee’s determinations under the Share Plans are at its sole discretion and will be final and binding on persons having an
interest in those Share Plans or associated Awards. 
 SECTION 3. ELIGIBILITY 

As determined by the Remuneration Committee, Service Providers are eligible to be granted Awards under the Share Plans set out in the following appendices:

  

	 	•	 	 Appendix A – Share Awards Plan 

 

	 	•	 	 Appendix B – Share Option and Grant Plan, comprised of; 

Appendix B1 – Share Option and Grant Plan Rules 

Appendix B2 – Incentive Share Option Award Agreement 

Appendix B3 – Non-qualified Share Option Award Agreement 

Appendix B4 – Early Exercise Non-qualified Share Option Award Agreement 

 It is envisaged that the Share Plans will be used as follows: 

 

	 	•	 	 UK-based employees will receive Awards under the Share Awards Plan in
Appendix A or under the Share Option and Grant Plan in Appendix B1 pursuant to the Non-Qualified Share Option Award Agreement in Appendix B3 or the Early Exercise
Non-Qualified Share Option Award Agreement in Appendix B4, 

  

	 	•	 	 US-based employees will receive Awards under the Share Option and Grant
Plan in Appendix B1 pursuant to the Incentive Share Option Award Agreement in Appendix B2 (provided the Incentive Share Option criteria are met), the Non-Qualified Share Option Award Agreement in Appendix B3
or the Early Exercise Non-Qualified Share Option Award Agreement in Appendix B4, and 

  

	 	•	 	 both UK and US non-employee Service Providers will receive Awards under
the Share Option and Grant Plan in Appendix B1 pursuant to the Non-Qualified Share Option Award Agreement in Appendix B3 (Non-qualifying) or the Early Exercise Non-Qualified Share Option Award Agreement in Appendix B4. 

 The Remuneration Committee may also
exercise its discretion to grant any other type or types of Awards permitted under the Share Option and Grant Plan. The Remuneration Committee will exercise its judgment and discretion in determining which Share Plan is appropriate and its decision
is final and binding. 
 To the extent that any conflict arises between this Omnibus Plan and any Share Plan, the relevant Share Plan shall prevail. 

SECTION 4. SHARES AVAILABLE 
 Under the amended and
restated Shareholders’ Agreement dated 18 November 2020, an Incentivisation Pool of Ordinary Shares (as defined in the Company’s articles of association) of up to 15% of the current fully diluted share capital has been established
which shall be increased following the second tranche of investment to ensure the Incentivisation Pool of Ordinary Shares continues to consist of up to 15% of the fully diluted share capital following such further investment. Within this limit, the
amount and terms of individual Awards shall be determined by the Remuneration Committee. 
 It is further noted that the number of Ordinary Shares over
which options can be issued under the Share Option and Grant Plan in Appendix B1 is subject to the fixed limit set out therein. If this limit is ever increased, it will require shareholder approval. 

SECTION 5. TAX WITHHOLDING 
 Each Service Provider
shall make arrangements satisfactory to the Remuneration Committee regarding indemnity for and payment of, any taxes of any kind required by law to be withheld by the Company or the Employer with respect to Awards. The Company and any Subsidiary
shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee.

 SECTION 6. AMENDMENTS AND TERMINATION 

The Remuneration Committee may, at any time, amend or discontinue the Omnibus Plan or any Share Plan and the Remuneration Committee may, at any time, amend or
cancel any outstanding Award for the purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the consent of the holder of the Award.

	SECTION 3.	 ORDINARY SHARES UNDER THE PLAN; MERGERS AND OTHER TRANSACTIONS; SUBSTITUTION

 (a) Ordinary Shares under the Plan. Subject to the overall limitation set forth in Section 4 of the Omnibus
Plan, the maximum number of Shares reserved and available for issuance under the Plan shall be 19,167,938, subject to adjustment as provided in Section 3(b). For purposes of this limitation, the Ordinary Shares underlying any Awards that
are forfeited, canceled, reacquired by the Company prior to vesting, satisfied without the issuance of Shares or otherwise terminated (other than by exercise) and Ordinary Shares that are withheld upon exercise of an Option or settlement of an Award
to cover the exercise price or tax withholding shall be added back to the Ordinary Shares available for issuance under the Plan. Subject to such overall limitations, Shares may be issued up to such maximum number pursuant to any type or types of
Award, and no more than 19,167,938 Shares may be issued pursuant to Incentive Share Options. The Shares available for issuance under the Plan may be authorized but unissued Shares or Shares reacquired by the Company. 

(b) Changes in Ordinary Shares. Subject to Section 3(c) hereof, if, as a result of any reorganization, recapitalization,
reclassification, share dividend, share split, reverse share split or 

  
 6 

 
other similar change in the Company’s share capital, the number of outstanding Ordinary Shares are increased or decreased or are exchanged for a different number or kind of shares or other
securities of the Company, or additional Ordinary Shares or new or different shares or other securities of the Company, or other non-cash assets are distributed with respect to such Ordinary Shares or other
securities, in each case, without the receipt of consideration by the Company, or, if, as a result of any merger or consolidation, or sale of all or substantially all of the assets of the Company, the outstanding Ordinary Shares are converted into
or exchanged for other securities of the Company or any successor entity (or a parent or subsidiary thereof), then the Committee shall make an appropriate and proportionate adjustment in (i) the maximum number of Ordinary Shares reserved for
issuance under the Plan, (ii) the number and kind of Ordinary Shares or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per Ordinary Share subject to each outstanding Award, and
(iv) the exercise price for each Ordinary Share subject to any then outstanding Share Options under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Share Options) as to which such
Share Options remain exercisable. The Committee shall in any event make such adjustments as may be required by Section 25102(o) of the California Corporation Code and the rules and regulations promulgated thereunder. The adjustment by the
Committee shall be final, binding and conclusive. No fractional Ordinary Shares shall be issued under the Plan resulting from any such adjustment, but the Committee in its discretion may make a cash payment in lieu of fractional shares. 

(c) Sale Events. Upon a Sale Event pursuant to this Section 3(c), the Company shall not be required to treat all Options or other
Awards under the Plan, or classes of Options or other Awards, in the same manner and can provide for different treatment for different holders or classes of Options or other Awards in the Company’s sole discretion. 

(i) Options.1 

(A) In the case of and subject to the consummation of a Sale Event, the Plan and all outstanding Options issued hereunder shall
terminate upon the effective time of any such Sale Event unless assumed or continued by the successor entity, or new share options or other awards of the successor entity or parent thereof are substituted therefor, with an equitable or proportionate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree (after taking into account any
acceleration hereunder and/or pursuant to the terms of any Award Agreement). 
 (B) In the event of the termination of the
Plan and all outstanding Options issued hereunder pursuant to Section 3(c), except as otherwise provided for by the Committee, each Holder of Options shall be permitted, within a period of time prior to the consummation of the Sale Event as
specified by the Committee, to exercise all such Options which are then exercisable or will become exercisable as of the effective time of the Sale Event; provided, however, that the exercise of Options not exercisable prior to the Sale Event
shall be subject to the consummation of the Sale Event. 

  
 7 

 (C)    Notwithstanding anything to the contrary in
Section 3(c)(i)(A), in the event of a Sale Event, the Company shall have the right, but not the obligation, to make or provide for a cash payment to all or some Holders of Options, without any consent of the Holders, in exchange for the
cancellation thereof, in an amount equal to the difference between (A) the value as determined by the Committee of the consideration payable per Ordinary Share pursuant to the Sale Event (the “Sale Price”) times the number of Ordinary
Shares subject to outstanding Options being cancelled (to the extent then vested and exercisable, including by reason of acceleration in connection with such Sale Event, at prices not in excess of the Sale Price) and (B) the aggregate exercise
price of all such outstanding vested and exercisable Options. For the avoidance of doubt, if the per share exercise price with respect to any Option equals or exceeds the Sale Price, such Option may be cancelled without consent of any Holder and
without any consideration therefor. 
 (ii) Restricted Shares and Restricted Share Unit Awards. 

(A) In the case of and subject to the consummation of a Sale Event, all unvested Restricted Shares and unvested Restricted
Share Unit Awards (other than those becoming vested as a result of the Sale Event) issued hereunder shall be forfeited immediately prior to the effective time of any such Sale Event unless assumed or continued by the successor entity, or awards of
the successor entity or parent thereof are substituted therefor, with an equitable or proportionate adjustment as to the number and kind of shares subject to such awards as such parties shall agree (after taking into account any acceleration
hereunder and/or pursuant to the terms of any Award Agreement). 
 (B) In the event of the forfeiture of Restricted Shares
pursuant to Section 3(c)(ii)(A), such Restricted Shares shall be repurchased from the Holder thereof at a price per share equal to the original per share purchase price paid by the Holder (subject to adjustment as provided in Section 3(b))
for such Shares. 
 (C) Notwithstanding anything to the contrary in Section 3(c)(ii)(A), in the event of a Sale Event,
the Company shall have the right, but not the obligation, to make or provide for a cash payment to the Holders of Restricted Shares or Restricted Share Unit Awards, without consent of the Holders, in exchange for the cancellation thereof, in an
amount equal to the Sale Price times the number of Shares subject to such Awards, to be paid at the time of such Sale Event or upon the later vesting of such Awards. 

SECTION 4. ELIGIBILITY 
 Grantees under
the Plan will be such full or part-time officers and other employees, directors, Consultants and key persons of the Group who are selected from time to time by the Committee in its sole discretion; provided, however, that Awards shall
be granted only to those individuals described in Rule 701(c) of the Securities Act. 
 SECTION 5. SHARE OPTIONS 

Upon the grant of a Share Option, the Company and the grantee shall enter into an Award Agreement. The terms and conditions of each such Award
Agreement shall be determined by the Committee, and such terms and conditions may differ among individual Awards and grantees. 

  
 8 

 Share Options granted under the Plan may be either Incentive Share Options or Non-Qualified Share Options. Incentive Share Options may be granted only to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the
Code. To the extent that any Option does not qualify as an Incentive Share Option, it shall be deemed a Non-Qualified Share Option. 

(a) Terms of Share Options. The Committee in its discretion may grant Share Options to those individuals who meet
the eligibility requirements of Section 4. Share Options shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Committee shall deem
desirable. The vesting of any Shares Options, and the vesting of any Shares underlying the Share Options, shall be governed by this Plan and the applicable Award Agreement, and any such vesting provisions shall supersede the vesting provisions set
forth in the Articles of Association.2 
 (i) Exercise Price. The exercise price
per share for the Ordinary Shares covered by a Share Option shall be determined by the Committee at the time of grant but shall not be less than 100 percent of the Fair Market Value on the Grant Date. In the case of an Incentive Share Option
that is granted to a Ten Percent Owner, the exercise price per share for the Ordinary Shares covered by such Incentive Share Option shall not be less than 110 percent of the Fair Market Value on the Grant Date. Notwithstanding the foregoing,
Share Options may be granted with an exercise price per share that is less than 100 percent of the Fair Market Value on the date of grant (i) to individuals who are not subject to U.S. income tax or (ii) the Share Option is otherwise
compliant with or exempt from Section 409A. 
 (ii) Option Term. The term of each Share Option shall be fixed by the Committee,
but no Share Option shall be exercisable more than ten years from the Grant Date. In the case of an Incentive Share Option that is granted to a Ten Percent Owner, the term of such Share Option shall be no more than five years from the Grant
Date. 
 (iii) Exercisability; Rights of a Shareholder. Share Options shall become exercisable and/or vested at such time or times,
whether or not in installments, as shall be determined by the Committee at or after the Grant Date. The Award Agreement may permit a grantee to exercise all or a portion of a Share Option immediately at grant; provided that the Shares issued upon
such exercise shall be subject to restrictions and a vesting schedule identical to the vesting schedule of the related Share Option, such Shares shall be deemed to be Restricted Shares for purposes of the Plan, and the optionee may be required to
enter into an additional or new Award Agreement as a condition to exercise of such Share Option. An optionee shall have the rights of a shareholder only as to Ordinary Shares acquired upon the exercise of a Share Option and not as to unexercised
Share Options. An optionee shall not be deemed to have acquired any Ordinary Shares unless and until a Share Option shall have been exercised pursuant to the terms of the Award Agreement and this Plan and the optionee’s name has been entered on
the books of the Company as a shareholder. 

  
 9 

 (iv) Method of Exercise. Share Options may be exercised by an optionee in whole or in
part, by the optionee giving written or electronic notice of exercise to the Company, specifying the number of Ordinary Shares to be purchased. Payment of the purchase price may be made by one or more of the following methods (or any combination
thereof) to the extent provided in the Award Agreement: 
 (A) In cash, by certified or bank check, by wire transfer of
immediately available funds, or other instrument acceptable to the Committee; 
 (B) If permitted by the Committee, by the
optionee delivering to the Company a promissory note, if the Board has expressly authorized the loan of funds to the optionee for the purpose of enabling or assisting the optionee to effect the exercise of his or her Share Option; provided,
that at least so much of the exercise price as represents the nominal value of the Shares shall be paid in cash if required by state law; 

(C) If permitted by the Committee and the Initial Public Offering has occurred (or the Shares otherwise becomes
publicly-traded), through the delivery (or attestation to the ownership) of Shares that have been purchased by the optionee on the open market or that are beneficially owned by the optionee and are not then subject to restrictions under any Company
plan. To the extent required to avoid variable accounting treatment under ASC 718 or other applicable accounting rules, such surrendered Shares if originally purchased from the Company shall have been owned by the optionee for at least six months.
Such surrendered Shares shall be valued at Fair Market Value on the exercise date; 
 (D) If permitted by the Committee and
the Initial Public Offering has occurred (or the Shares otherwise becomes publicly-traded), by the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the
Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures and
enter into such agreements of indemnity and other agreements as the Committee shall prescribe as a condition of such payment procedure; or 

(E) If permitted by the Committee, and only with respect to Share Options that are not Incentive Share Options, by a “net
exercise” arrangement pursuant to which the Company will reduce the number of Shares issuable upon exercise by the largest whole number of Shares with a Fair Market Value that does not exceed the aggregate exercise price. 

Payment instruments will be received subject to collection. No Shares so purchased will be issued to the optionee and no transfer to the
optionee on the records of the Company will take place, until the Company has completed all steps it has deemed necessary to satisfy legal requirements relating to the issuance and sale of the Ordinary Shares, which steps

  
 10 

 
may include, without limitation, (i) receipt of a representation from the optionee at the time of exercise of the Option that the optionee is purchasing the Ordinary Shares for the
optionee’s own account and not with a view to any sale or distribution of the Ordinary Shares or other representations relating to compliance with applicable law governing the issuance of securities, (ii) the legending of the certificate
(or notation on any book entry) representing the Ordinary Shares to evidence the foregoing restrictions, and (iii) obtaining from optionee payment or provision for all withholding taxes due as a result of the exercise of the Option. The
delivery of certificates representing the Ordinary Shares (or the transfer to the optionee on the records of the Company with respect to uncertificated Ordinary Shares) to be purchased pursuant to the exercise of a Share Option will be contingent
upon (A) receipt from the optionee (or a purchaser acting in his or her stead in accordance with the provisions of the Share Option) by the Company of the full purchase price for such Ordinary Shares and the fulfillment of any other
requirements contained in the Award Agreement or applicable provisions of laws and (B) if required by the Company, the optionee shall have entered into any shareholders agreements or other agreements with the Company and/or certain other of the
Company’s shareholders. In the event an optionee chooses to pay the purchase price by previously-owned Shares through the attestation method, the number of Shares transferred to the optionee upon the exercise of the Share Option shall be net of
the number of Shares attested to.  
 (b) Annual Limit on Incentive Share Options. To the extent required
for “incentive stock option” treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the Grant Date) of the Ordinary Shares with respect to which Incentive Share Options granted under the Plan and
any other plan of the Company or its parent and any Subsidiary that become exercisable for the first time by an optionee during any calendar year shall not exceed USD $100,000 or such other limit as may be in effect from time to time under
Section 422 of the Code. To the extent that any Share Option exceeds this limit, it shall constitute a Non-Qualified Share Option. 

(c) Termination. Any portion of a Share Option that is not vested and exercisable on the date of termination of an optionee’s
Service Relationship shall immediately expire and be null and void. Once any portion of the Share Option becomes vested and exercisable, the optionee’s right to exercise such portion of the Share Option (or the optionee’s representatives
and legatees as applicable) in the event of a termination of the optionee’s Service Relationship shall continue until the earliest of: (i) the date which is: (A) 12 months following the date on which the optionee’s Service
Relationship terminates due to death or Disability (or such longer period of time as determined by the Committee and set forth in the applicable Award Agreement), or (B) three months following the date on which the optionee’s Service
Relationship terminates if the termination is due to any reason other than death or Disability (or such longer period of time as determined by the Committee and set forth in the applicable Award Agreement), or (ii) the Expiration Date set forth
in the Award Agreement; provided that notwithstanding the foregoing, except as otherwise provided in an Award Agreement, if the optionee’s Service Relationship is terminated for Cause, the Share Option shall terminate immediately and be
null and void upon the date of the optionee’s termination and shall not thereafter be exercisable.

	SECTION 6.	 RESTRICTED SHARE AWARDS 

(a) Nature of Restricted Share Awards. The Committee may, in its sole discretion, grant (or sell at par value or such other purchase
price determined by the Committee) to an eligible individual under Section 4 hereof a Restricted Share Award under the Plan. The Committee shall determine the restrictions and conditions applicable to each Restricted Share Award at the time of
grant. Conditions may be based on continuing employment (or other Service Relationship), achievement of pre-established performance goals and objectives and/or such other criteria as the Committee may
determine. Upon the grant of a Restricted Share Award, the Company and the grantee shall enter into an Award Agreement. The terms and conditions of each such Award Agreement shall be determined by the Committee, and such terms and conditions may
differ among individual Awards and grantees. 
 (b) Rights as a Shareholder. Upon the grant of the Restricted Share Award and payment
of any applicable purchase price, a grantee of Restricted Shares shall be considered the record owner of and shall be entitled to vote the Restricted Shares if, and to the extent, such Shares are entitled to voting rights, subject to such conditions
contained in the Award Agreement. The grantee shall be entitled to receive all dividends and any other distributions declared on the Shares; provided, however, that the Company is under no duty to declare any such dividends or to make
any such distribution. Unless the Committee shall otherwise determine, certificates evidencing the Restricted Shares shall remain in the possession of the Company until such Restricted Shares are vested as provided in subsection (d) below of
this Section, and the grantee shall be required, as a condition of the grant, to deliver to the Company a share power endorsed in blank and such other instruments of transfer as the Committee may prescribe. 

(c) Restrictions. Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as
specifically provided herein or in the Award Agreement. Except as may otherwise be provided by the Committee either in the Award Agreement or, subject to Section 12 below, in writing after the Award Agreement is issued, if a grantee’s
Service Relationship with the Company and any Subsidiary terminates, the Company or its assigns shall have the right, as may be specified in the relevant instrument, to repurchase some or all of the Shares subject to the Award at such purchase price
as is set forth in the Award Agreement. 
 (d) Vesting of Restricted Shares. The Committee at the time of grant shall specify in the
Award Agreement the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the substantial risk of forfeiture imposed shall lapse and the Restricted
Shares shall become vested, subject to such further rights of the Company or its assigns as may be specified in the Award Agreement. Vesting of any such Restricted Shares shall specifically be governed by this Plan and the applicable Award
Agreement, and shall supersede the vesting provisions set forth in the Articles of Association. 
  

	SECTION 7.	 UNRESTRICTED SHARE AWARD 

(a) The Committee may, in its sole discretion, grant (or sell at par value or such other purchase price determined by the Committee) to an
eligible person under Section 4 hereof an 

  
 12 

 
Unrestricted Share Award under the Plan. Unrestricted Share Awards may be granted in respect of past services or other valid consideration, or in lieu of cash compensation due to such grantee.
Such Shares shall not be subject to any vesting provisions set forth in the Articles of Association. 
  

	SECTION 8.	 RESTRICTED SHARE UNITS 

(a) Nature of Restricted Share Units. The Committee may, in its sole discretion, grant to an eligible person under Section 4 hereof
Restricted Share Units under the Plan. The Committee shall determine the restrictions and conditions applicable to each Restricted Share Unit at the time of grant. Vesting conditions may be based on continuing employment (or other Service
Relationship), achievement of pre-established performance goals and objectives and/or other such criteria as the Committee may determine. Upon the grant of Restricted Share Units, the grantee and the Company
shall enter into an Award Agreement. The terms and conditions of each such Award Agreement shall be determined by the Committee and may differ among individual Awards and grantees. On or promptly following the vesting date or dates applicable to any
Restricted Share Unit, but in no event later than March 15 of the year following the year in which such vesting occurs, such Restricted Share Unit(s) shall be settled in the form of cash or Shares, as specified in the Award Agreement.
Restricted Share Units may not be sold, assigned, transferred, pledged, or otherwise encumbered or disposed of. 
 (b) Rights as a
Shareholder. A grantee shall have the rights of a shareholder only as to Shares, if any, acquired upon settlement of Restricted Share Units. A grantee shall not be deemed to have acquired any such Shares unless and until the Restricted Share
Units shall have been settled in Shares pursuant to the terms of the Plan and the Award Agreement, the Company shall have issued and delivered a certificate representing the Shares to the grantee (or transferred on the records of the Company with
respect to uncertificated shares), and the grantee’s name has been entered in the books of the Company as a shareholder. Any Shares acquired upon settlement of Restricted Share Units shall be vested and shall not be subject to the vesting
provisions of the Articles of Association. 
 (c) Termination. Except as may otherwise be provided by the Committee either in the
Award Agreement or in writing after the Award Agreement is issued, a grantee’s right in all Restricted Share Units that have not vested shall automatically terminate upon the grantee’s cessation of Service Relationship with the Company and
any Subsidiary for any reason. 
  

	SECTION 9.	 TRANSFER RESTRICTIONS; COMPANY RIGHT OF FIRST REFUSAL; COMPANY REPURCHASE RIGHTS 

(a) Restrictions on Transfer. 

(i) Non-Transferability of Share Options. Share Options and, prior to
exercise, the Ordinary Shares issuable upon exercise of such Share Option, shall not be transferable by the optionee otherwise than by will, or by the laws of descent and distribution, and all Share Options shall be exercisable, during the
optionee’s lifetime, only by the optionee, or by the optionee’s legal representative or guardian in the event of the optionee’s incapacity. 

  
 13 

 
3Share Options, and the Ordinary Shares issuable upon exercise of such Share Options, shall be restricted as to any pledge, hypothecation, or
other transfer, including any short position, any “put equivalent position” (as defined in the Exchange Act) or any “call equivalent position” (as defined in the Exchange Act) prior to exercise. 

(ii) Shares. The transfer of any Ordinary Shares (other than any unvested Ordinary Shares, which by their terms are not transferable)
shall be subject to the provisions of the Articles of Association. 
 (b) Intentionally Omitted. 

(c) Company’s Right of Repurchase. 

(i) Right of Repurchase for Shares Issued Upon the Exercise of an Option. Upon a Termination Event, the Company or its assigns shall
have the right and option to repurchase from a Holder of Shares acquired upon exercise of a Share Option (i) any Ordinary Shares which are still subject to a risk of forfeiture (i.e., unvested) as of the Termination Event and (ii) in the
case of a Termination Event that is a termination for Cause, any Ordinary Shares acquired upon exercise of a Share Option, whether or not vested. Such repurchase rights may be exercised by the Company within the later of (A) six months
following the date of such Termination Event or (B) seven months after the acquisition of Shares upon exercise of a Share Option. The repurchase price shall be equal to the lower of the original per share price paid by the Holder, subject to
adjustment as provided in Section 3(b) of the Plan, or the current Fair Market Value of such Shares as of the date the Company elects to exercise its repurchase rights. 

(ii) Right of Repurchase With Respect to Restricted Shares. Upon a Termination Event, the Company or its assigns shall have the right
and option to repurchase from a Holder of Shares received pursuant to a Restricted Share Award (i) any Ordinary Shares that are still subject to a risk of forfeiture (i.e., unvested) as of the Termination Event and (ii) in the case of a
Termination Event that is a termination for Cause, any Ordinary Shares received pursuant to a Restricted Share Award, whether or not vested. Such repurchase right may be exercised by the Company within six months following the date of such
Termination Event. The repurchase price shall be the lower of the original per share purchase price paid by the Holder, subject to adjustment as provided in Section 3(b) of the Plan, or the current Fair Market Value of such Shares as of the
date the Company elects to exercise its repurchase rights. 
 (iii) Procedure. Any repurchase right of the Company shall be exercised
by the Company or its assigns by giving the Holder written notice on or before the last day of the repurchase period of its intention to exercise such repurchase right. Upon such notification, the Holder shall promptly surrender to the Company, free
and clear of any liens or encumbrances, any certificates (to the extent certificated) representing the Shares being purchased. Upon the Company’s or its assignee’s receipt of the certificates from the Holder, the Company or its assignee or
assignees shall deliver to him, her or them a check for the applicable repurchase price; provided, however, that the Company may pay the repurchase price by offsetting and canceling any indebtedness then owed by the Holder to the Company.

  
 14 

 (d) Escrow Arrangement4.

 (i) Escrow. In order to carry out the provisions of this Section 9 of this Plan more effectively, the Company shall hold any
Ordinary Shares issued pursuant to Awards granted under the Plan in escrow. The Company shall not dispose of the Ordinary Shares except as otherwise provided in this Plan. In the event of any repurchase by the Company (or any of its assigns), the
Company is hereby authorized by the Holder, as the Holder’s attorney-in-fact, to date and complete the transfer of the Ordinary Shares being purchased and to
transfer such Ordinary Shares in accordance with the terms hereof. At such time as any Ordinary Shares are no longer subject to the Company’s repurchase and first refusal rights, the Company shall, at the written request of the Holder, deliver
to the Holder the Ordinary Shares. 
 (ii) Remedy. Without limitation of any other provision of this Plan or other rights, in the
event that a Holder or any other Person is required to sell a Holder’s Ordinary Shares pursuant to the provisions of Sections 9(b) or (c) hereof and in the further event that he or she refuses or for any reason fails to deliver to the
Company or its designated purchaser such Ordinary Shares, the Company or such designated purchaser may deposit the applicable purchase price for such Ordinary Shares with a bank designated by the Company, or with the Company’s independent
public accounting firm, as agent or trustee, or in escrow, for such Holder or other Person, to be held by such bank or accounting firm for the benefit of and for delivery to him, her, them or it, and/or, in its discretion, pay such purchase price by
offsetting any indebtedness then owed by such Holder as provided above. Upon any such deposit and/or offset by the Company or its designated purchaser of such amount and upon notice to the Person who was required to sell the Ordinary Shares to be
sold pursuant to the provisions of Sections 9, such Ordinary Shares shall at such time be deemed to have been sold, assigned, transferred and conveyed to such purchaser, such Holder shall have no further rights thereto (other than the right to
withdraw the payment thereof held in escrow, if applicable), and the Company shall record such transfer in its shareholder register. 
 (e)
Lockup Provision. If requested by the Company, a Holder shall not sell or otherwise transfer or dispose of any Ordinary Shares (including, without limitation, pursuant to Rule 144 under the Securities Act) held by him or her for such period
following the effective date of a public offering by the Company of Ordinary Shares as the Company shall specify reasonably and in good faith. If requested by the underwriter engaged by the Company, each Holder shall execute a separate letter
confirming his or her agreement to comply with this Section. 
 (f) Adjustments for Changes in Capital Structure. If, as a result of
any reorganization, recapitalization, reclassification, share dividend, share split, reverse share split or other similar change in the Ordinary Shares, the number of outstanding Ordinary Shares are increased or decreased or are exchanged for a
different number or kind of securities of the Company, the restrictions contained in this Section 9 shall apply with equal force to additional and/or substitute securities, if any, received by Holder in exchange for, or by virtue of his or her
ownership of, Ordinary Shares. 

  
 15 

 (g) Termination. The terms and provisions of Section 9(b) and Section 9(c)
(except for the Company’s right to repurchase Shares still subject to a risk of forfeiture upon a Termination Event) shall terminate upon the closing of the Company’s Initial Public Offering or upon consummation of any Sale Event, in
either case as a result of which Ordinary Shares are registered under Section 12 of the Exchange Act and publicly-traded on any national security exchange. 

SECTION 10. TAX WITHHOLDING 
 (a)
Payment by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any Ordinary Shares or other amounts received thereunder first becomes includable in the gross income of the grantee for income tax
purposes, pay to the Company or the Employer, or make arrangements satisfactory to the Committee regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld by the Company or the Employer with respect to such
income. The Company and any Subsidiary shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee. The Company’s or the Employer’s obligation to
deliver any Ordinary Shares (or evidence of book entry) to any grantee is subject to and conditioned on any such tax withholding obligations being satisfied by the grantee. 

(b) Payment in Shares. The Company’s or Employer’s required tax withholding obligation may be satisfied, in whole or
in part, by the Company and/or the Employer (i) withholding from Ordinary Shares to be delivered pursuant to an Award a number of Ordinary Shares having an aggregate Fair Market Value (as of the date the withholding is effected) that would
satisfy the withholding amount due or (ii) following an IPO, causing its transfer agent to sell a number of Shares with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due
and remitting the proceeds from such sale to the Company. 
 (c) UK national insurance contributions. At the request of the Company
or Subsidiary by which the relevant grantee is employed at any time before the vesting or exercise of an Award which is an Option, the grantee must either agree to meet or elect, to the extent lawfully permitted (and in the case of an election,
using a form approved by HM Revenue & Customs) that the whole of the liability for any secondary class 1 (employers’) national insurance contributions arising as a result of the grant, release, exercise, assignment or surrender
for consideration of the Share Option, shall be borne by or transferred to the grantee.5 
 SECTION 11.
SECTION 409A AWARDS.  
 To the extent that any Award is determined to constitute “nonqualified deferred
compensation” within the meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements as may be specified by the Committee from 

  
 16 

 
time to time. In this regard, if any amount under a 409A Award is payable upon a “separation from service” (within the meaning of Section 409A) to a grantee who is considered a
“specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that is the earlier of (i) six months and one day after the grantee’s separation from service, or (ii) the
grantee’s death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or additional tax imposed pursuant to Section 409A. To the extent that any provision of the Plan or an
Award Agreement is ambiguous as to its compliance with Section 409A, such provision shall be interpreted in such a manner so that all payments thereunder comply with Section 409A. The Company makes no representation or warranty and shall
have no liability to any grantee under the Plan or any other Person with respect to any penalties or taxes under Section 409A that are, or may be, imposed with respect to any Award. 

SECTION 12. AMENDMENTS AND TERMINATION 

The Board may, at any time, amend or discontinue the Plan and the Committee may, at any time, amend or cancel any outstanding Award for the
purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the consent of the holder of the Award. The Committee may exercise its discretion to reduce
the exercise price of outstanding Share Options or effect repricing through cancellation of outstanding Share Options and by granting such holders new Awards in replacement of the cancelled Share Options. To the extent determined by the Committee to
be required either by the Code to ensure that Incentive Share Options granted under the Plan are qualified under Section 422 of the Code or otherwise, Plan amendments shall be subject to approval by the Company shareholders entitled to vote at
a meeting of shareholders. Nothing in this Section 12 shall limit the Board’s or Committee’s authority to take any action permitted pursuant to Section 3(c). The Board reserves the right to amend the Plan and/or the terms of any
outstanding Share Options to the extent reasonably necessary to comply with the requirements of the exemption pursuant to paragraph (f)(4) of Rule 12h-1 of the Exchange Act. 

SECTION 13. STATUS OF PLAN 
 With respect
to the portion of any Award that has not been exercised and any payments in cash, Shares or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the Committee
shall otherwise expressly so determine in connection with any Award. 
 SECTION 14. GENERAL PROVISIONS 

(a) No Distribution; Compliance with Legal Requirements. The Committee may require each person acquiring Shares pursuant to an Award to
represent to and agree with the Company in writing that such person is acquiring the Ordinary Shares without a view to distribution thereof. No Ordinary Shares shall be issued pursuant to an Award until all applicable securities law and other legal
and stock exchange or similar requirements have been satisfied. The Committee may require the placing of such stop-orders and restrictive legends for Shares and Awards as it deems appropriate 

  
 17 

 (b) Delivery of Shares. Shares shall be deemed delivered for all purposes when the
Company or a stock transfer agent of the Company shall have given to the grantee notice of issuance and recorded the issuance in its records (which may include electronic “book entry” records). 

(c) No Employment Rights. The adoption of the Plan and the grant of Awards do not confer upon any Person any right to continued
employment or Service Relationship with the Company or any Subsidiary. 
 (d) Trading Policy Restrictions. Option exercises and other
Awards under the Plan shall be subject to the Company’s insider trading policy-related restrictions, terms and conditions as may be established by the Committee, or in accordance with policies set by the Committee, from time to time. 

(e) Designation of Beneficiary. Each grantee to whom an Award has been made under the Plan may designate a beneficiary or beneficiaries
to exercise any Award on or after the grantee’s death or receive any payment under any Award payable on or after the grantee’s death. Any such designation shall be on a form provided for that purpose by the Committee and shall not be
effective until received by the Committee. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee’s estate. 

(f) Legend. The shareholders register of the Company shall, with respect to any Ordinary Shares held by a Holder, contain the following
notation: 
 The transferability of the Ordinary Shares are subject to the restrictions, terms and conditions (including repurchase
and restrictions against transfers) contained in Achilles TX Limited 2020 Share Option and Grant Plan and any agreements entered into thereunder by and between the company and the holder of the Ordinary Shares. 

(g) Information to Holders of Options. In the event the Company is relying on the exemption from the registration requirements of
Section 12(g) of the Exchange Act contained in paragraph (f)(1) of Rule 12h-1 of the Exchange Act, the Company shall provide the information described in Rule 701(e)(3), (4) and (5) of the Securities
Act to all holders of Options in accordance with the requirements thereunder. The foregoing notwithstanding, the Company shall not be required to provide such information unless the optionholder has agreed in writing, on a form prescribed by the
Company, to keep such information confidential. 
 SECTION 15. EFFECTIVE DATE OF PLAN 

The Plan shall become effective upon adoption by the Board and shall be approved by shareholders in accordance with applicable law and the
Company’s articles of association and bylaws within 12 months thereafter. If the shareholders fail to approve the Plan within 12 months after its adoption by the Board of Directors, then any Awards granted or sold under the Plan shall be
rescinded and no additional grants or sales shall thereafter be made under the Plan. Subject to such approval by shareholders and to the requirement that no Shares may be issued hereunder 

  
 18 

 
prior to such approval, Share Options and other Awards may be granted hereunder on and after adoption of the Plan by the Board. No grants of Share Options and other Awards may be made hereunder
after the tenth anniversary of the date the Plan is adopted by the Board or the date the Plan is approved by the Company’s shareholders, whichever is earlier. 

SECTION 16. GOVERNING LAW 
 This Plan, all
Awards and any controversy arising out of or relating to this Plan and all Awards shall be governed by and construed in accordance with the law of England and Wales, without regard to conflict of law principles that would result in the application
of any law other than the law of England and Wales.

 INCENTIVE SHARE OPTION AGREEMENT 

UNDER THE ACHILLES TX LIMITED 

2020 SHARE OPTION AND GRANT PLAN 

All capitalized terms used herein and not otherwise defined shall have the respective meanings set forth in the Grant Notice and the Plan.

 1. Vesting, Exercisability and Termination. 

(a) No portion of this Share Option may be exercised until such portion shall have vested and become exercisable. 

(b) Except as set forth below, and subject to the determination of the Committee in its sole discretion to accelerate the vesting schedule
hereunder, this Share Option shall be vested and exercisable on the respective dates indicated below: 
 (i) This Share
Option shall initially be unvested and unexercisable. 
 (ii) This Share Option shall vest and become exercisable in
accordance with the Vesting Schedule set forth in the Grant Notice. 
 (c) Termination. Except as may otherwise be provided by the
Committee, if the Optionee’s Service Relationship is terminated, the period within which to exercise this Share Option may be subject to earlier termination as set forth below (and if not exercised within such period, shall thereafter terminate
subject, in each case, to Section 3(c) of the Plan): 
 (i) Termination Due to Death or Disability. If the
Optionee’s Service Relationship terminates by reason of such Optionee’s death or Disability, this Share Option may be exercised, to the extent exercisable on the date of such termination, by the Optionee, the Optionee’s legal
representative or legatee for a period of 12 months from the later of (i) the date of death or Disability or (ii) a Liquidity Event, but in no event later than the Expiration Date, if earlier. 

(ii) Other Termination. If the Optionee’s Service Relationship terminates for any reason other than death or
Disability, and unless otherwise determined by the Committee, this Share Option may be exercised, to the extent exercisable on the date of termination, for a period of three months from the later of (i) the date of termination or (ii) a
Liquidity Event, but in no event later than the Expiration Date, if earlier; provided however, if the Optionee’s Service Relationship is terminated for Cause, this Share Option shall terminate immediately upon the date of such
termination. 
 For purposes hereof, (i) a “Liquidity Event” shall be the first to occur of a Sale Event or Initial Public
Offering and (ii) the Committee’s determination of the reason for termination of the Optionee’s Service Relationship shall be conclusive and binding on the Optionee and his or her representatives or legatees. Any portion of this Share
Option that is not vested and exercisable on the date of termination of the Service Relationship shall terminate immediately and be null and void. 

  
 3 

 (d) It is understood and intended that this Share Option is intended to qualify as an
“incentive stock option” as defined in Section 422 of the Code to the extent permitted under applicable law. Accordingly, the Optionee understands that in order to obtain the benefits of an incentive Share Option under
Section 422 of the Code, no sale or other disposition may be made of Shares for which incentive Share Option treatment is desired within the one-year period beginning on the day after the day of the
transfer of such Shares to him or her, nor within the two-year period beginning on the day after Grant Date of this Share Option and further that this Share Option must be exercised within three months after
termination of employment as an employee (or 12 months in the case of death or disability) to qualify as an incentive Share Option. If the Optionee disposes (whether by sale, gift, transfer or otherwise) of any such Shares within either of these
periods, he or she will notify the Company within 30 days after such disposition. The Optionee also agrees to provide the Company with any information concerning any such dispositions required by the Company for tax purposes. Further, to the extent
this Share Option and any other incentive Share Options of the Optionee having an aggregate Fair Market Value in excess of USD $100,000 (determined as of the Grant Date) first become exercisable in any year, such options will not qualify as
incentive Share Options. 
 2. Exercise of Share Option. 

(a) The Optionee may exercise this Share Option only in the following manner: Prior to the Expiration Date, the Optionee may deliver a Share
Option exercise notice (an “Exercise Notice”) in the form of Appendix A hereto indicating his or her election to purchase some or all of the Shares with respect to which this Share Option is then exercisable. Such notice shall
specify the number of Shares to be purchased. Payment of the purchase price may be made by one or more of the methods described in Section 5 of the Plan, subject to the limitations contained in such Section of the Plan, including the
requirement that the Committee specifically approve in advance certain payment methods. 
 (b) The Optionee, in relation to the exercise of
the Share Option, hereby undertakes that he/she shall enter into such elections as the Company may require pursuant to the provisions of: 

(i) section 431(1) of the Income Tax (Earnings and Pensions) Act 2003 (“ITEPA”) in the form prescribed by HM Revenue
and Customs to elect to pay income tax (if any) computed by reference to the unrestricted market value of the Employee Shares acquired (the “Election”) no later than fourteen (14) days after the subscription of the Employee Shares or

(i) Termination Due to Death or Disability. If the Optionee’s Service Relationship terminates by reason of such
Optionee’s death or Disability, this Share Option may continue to be exercised, to the extent the Shares are vested on the date of termination, by the Optionee, the Optionee’s legal representative or legatee for a period of 12 months from
the later of (i) the date of death or Disability or (ii) a Liquidity Event, but in no event later than the Expiration Date, if earlier. 

(ii) Other Termination. If the Optionee’s Service Relationship terminates for any reason other than death or
Disability, and unless otherwise determined by the Committee, this Share Option may continue to be exercised, to the extent the Shares are vested on the date of termination, for a period of three months from the later of (i) the date of
termination or (ii) a Liquidity Event, but in no event later than the Expiration Date, if earlier; provided however, if the Optionee’s Service Relationship is terminated for Cause, this Share Option shall terminate
immediately upon the date of such termination. 
 For purposes hereof, (i) a “Liquidity Event” shall be the first to occur of
a Sale Event or Initial Public Offering and (ii) the Committee’s determination of the reason for termination of the Optionee’s Service Relationship shall be conclusive and binding on the Optionee and his or her representatives or
legatees and any Permitted Transferee. Any portion of this Share Option with respect to Shares that are not vested and exercisable on the date of termination of the Service Relationship shall terminate immediately and be null and void.

 2. Exercise of Share Option. 

(a) The Optionee may exercise this Share Option only in the following manner: Prior to the Expiration Date, the Optionee may deliver a Share
Option exercise notice (an “Exercise Notice”) in the form of Appendix A hereto indicating his or her election to purchase some or all of the Shares. Such notice shall specify the number of Shares to be purchased.
To the extent this Share Option is only partially exercised, such exercise shall first be with respect to the Shares, if any, that have previously vested, and then with respect to the Shares that will next vest, with the Shares that vest at the
latest date being exercised last. Payment of the purchase price may be made by one or more of the methods described in Section 5 of the Plan, subject to the limitations contained in such Section of the Plan, including the requirement that the
Committee specifically approve in advance certain payment methods. 
 (b) In the event the Optionee exercises a portion of this Share Option
with respect to Shares that have not vested, the Optionee shall also deliver a Restricted Share Agreement covering such unvested Shares in the form of Appendix B hereto (the “Restricted Shares Agreement”) with the same vesting
schedule (and same Vesting Commencement Date) for such Shares as set forth for such Shares herein. 
 (c) The Optionee, in relation to the
exercise of the Share Option, hereby undertakes that he/she shall enter into such elections as the Company may require pursuant to the provisions of: 

(i) section 431(1) of the Income Tax (Earnings and Pensions) Act 2003 (“ITEPA”) in the form prescribed by HM Revenue
and Customs to elect to pay income tax (if any) computed by reference to the unrestricted market value of the Employee Shares acquired (the “Election”) no later than fourteen (14) days after the subscription of the Employee Shares or
such longer period as HM Revenue and Customs (the “HMRC”) direct; and 
 (ii) the Social Security Contributions and
Benefits Act 1992 and enter into any such associated arrangements as required by the Company (including, in the case of an election pursuant to paragraph 2(b)(i), such arrangements as would satisfy HMRC in relation to the question of whether the
obligation to pay the transferred liability is appropriately secured). 
 (d) Notwithstanding any other provision hereof or of the Plan, no
portion of this Share Option shall be exercisable after the Expiration Date. 
 3. Incorporation of Plan. Notwithstanding anything
herein to the contrary, this Share Option shall be subject to and governed by all the terms and conditions of the Plan. 
 4.
Transferability of Share Option. This Share Option is personal to the Optionee and is not transferable by the Optionee in any manner other than by will or by the laws of 

  
 4 

 
descent and distribution. The Share Option may be exercised during the Optionee’s lifetime only by the Optionee (or by the Optionee’s guardian or personal representative in the event of
the Optionee’s incapacity). The Optionee may elect to designate a beneficiary by providing written notice of the name of such beneficiary to the Company, and may revoke or change such designation at any time by filing written notice of
revocation or change with the Company; such beneficiary may exercise the Optionee’s Share Option in the event of the Optionee’s death to the extent provided herein. If the Optionee does not designate a beneficiary, or if the designated
beneficiary predeceases the Optionee, the legal representative of the Optionee may exercise this Share Option to the extent provided herein in the event of the Optionee’s death. 

5. Restrictions on Transfer of Shares. The Shares acquired upon exercise of the Share Option shall be subject to certain transfer
restrictions and other limitations including, without limitation, the provisions contained in Section 9 of the Plan and, if applicable, the Restricted Share Agreement. 

6. Miscellaneous Provisions. 

(a) Equitable Relief. The parties hereto agree and declare that legal remedies may be inadequate to enforce the provisions of this
Agreement and that equitable relief, including specific performance and injunctive relief, may be used to enforce the provisions of this Agreement. 

(b) Adjustments for Changes in Capital Structure. If, as a result of any reorganization, recapitalization, reincorporation,
reclassification, share dividend, share split, reverse share split or other similar change in the Company’s share capital, the outstanding Ordinary Shares are increased or decreased or are exchanged for a different number or kind of shares of
the Company, the restrictions contained in this Agreement shall apply with equal force to additional and/or substitute securities, if any, received by the Optionee in exchange for, or by virtue of his or her ownership of, this Share Option or Shares
acquired pursuant thereto. 
 (c) Change and Modifications. This Agreement may not be orally changed, modified or terminated, nor
shall any oral waiver of any of its terms be effective. This Agreement may be changed, modified or terminated only by an agreement in writing signed by the Company and the Optionee. 

(d) Governing Law. This Agreement shall be governed by and construed in accordance with the law of England and Wales, without regard to
conflict of law principles that would result in the application of any law other than the law of England and Wales. 
 (e) Headings.
The headings are intended only for convenience in finding the subject matter and do not constitute part of the text of this Agreement and shall not be considered in the interpretation of this Agreement. 

(f) Saving Clause. If any provision(s) of this Agreement shall be determined to be illegal or unenforceable, such determination shall
in no manner affect the legality or enforceability of any other provision hereof. 

  
 5 

 (g) Notices. All notices, requests, consents and other communications shall be in
writing and be deemed given when delivered personally, by telex or facsimile transmission or when received if mailed by first class registered or certified mail, postage prepaid. Notices to the Company or the Optionee shall be addressed as set forth
underneath their signatures below, or to such other address or addresses as may have been furnished by such party in writing to the other. 

(h) Benefit and Binding Effect. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto, their
respective successors, assigns, and legal representatives. The Company has the right to assign this Agreement, and such assignee shall become entitled to all the rights of the Company hereunder to the extent of such assignment. 

(i) Counterparts. For the convenience of the parties and to facilitate execution, this Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same document. 
 (j)
Integration. This Agreement constitutes the entire agreement between the parties with respect to this Share Option and supersedes all prior agreements and discussions between the parties concerning such subject matter.
