(b) Registration of transfer. As soon as practicable after the Custodian receives Deposited Securities pursuant to any such deposit or pursuant to paragraph (10) ( Distributions on Deposited Securities ) or (13) ( Changes Affecting Deposited Securities ) of the form of ADR, the Custodian shall present such Deposited Securities for registration of transfer into the name of the Depositary, the Custodian or a nominee of either, to the extent such registration is practicable, at the cost and expense of the person making such deposit (or for whose benefit such deposit is made) and shall obtain evidence satisfactory to it of such registration.

(c) Delivery of Deposited Securities. Deposited Securities shall be held by the Custodian for the account and to the order of the Depositary for the benefit of Holders of ADRs (to the extent not prohibited by law) at such place or places and in such manner as the Depositary shall determine. Deposited Securities may be delivered by

4

the Custodian to any person only under the circumstances expressly contemplated in this Deposit Agreement. To the extent that the provisions of or governing the Shares make delivery of certificates therefor impracticable, Shares may be deposited hereunder by such delivery thereof as the Depositary or the Custodian may reasonably accept, including, without limitation, by causing them to be credited to an account maintained by the Custodian for such purpose with the Company or an accredited intermediary, such as a bank, acting as a registrar for the Shares, together with delivery of the documents, payments and Delivery Order referred to herein to the Custodian or the Depositary. The Company agrees to notify the Depositary of any changes in the laws of the Cayman Islands, the ROC or otherwise which would permit deposits to be freely accepted hereunder.

(d) Until the Depositary is notified otherwise, under current ROC law, no deposit of Shares may be made hereunder, and no additional ADSs may be issued in respect thereof, without specific ROC regulatory approval, except in connection with: (i) stock dividends on, or free distributions of, Shares; (ii) the exercise by Holders of their pre-emptive rights in connection with capital increases for cash or (iii) the purchase directly by any person or through the Depositary or its agent of Shares on the Taipei Exchange for delivery of Shares to the Custodian or the delivery of Shares already held to the Custodian for deposit; provided that the total number of ADSs outstanding after an issuance described in clause 3(iii) hereunder does not exceed the number of issued ADSs previously approved by the FSC (plus any ADSs created pursuant to clauses 3(i) and 3(ii) above). Under current ROC law, issuances under clause 3(iii) above will be permitted only to the extent that previously issued ADSs have been cancelled and as permitted hereunder. At its discretion, the Depositary may refuse to accept Shares for deposit under clause 3(iii) above unless it receives satisfactory evidence or notification from the Company to the effect that the Shares may be lawfully deposited.

(e) Restricted American Depositary Shares. The Depositary may from time to time, at the written request and expense of the Company, establish procedures enabling the deposit hereunder of Shares that are Restricted Securities in order to enable the Depositary to issue Restricted ADRs representing such deposited Shares (such Shares that are Restricted Securities being “ Restricted Shares ” and the ADRs evidencing such Restricted ADSs being “ Restricted ADRs ”). The Company shall assist the Depositary in the establishment of such procedures and agrees that it shall take all steps necessary and reasonably satisfactory to the Depositary to ensure that the establishment of such procedures does not violate the provisions of the Securities Act of 1933 or any other applicable laws. The depositors of such Restricted Shares and the holders of the Restricted ADSs may be required prior to the deposit of such Restricted Shares, the transfer of the Restricted ADRs and the Restricted ADSs evidenced thereby or the withdrawal of the Restricted Shares represented by Restricted ADSs to provide such written certifications, opinions of counsel and/or agreements as the Depositary or

5

the Company may require. The Company shall provide to the Depositary in writing the legend(s) (the “ Legends ”) to be included in the account statements issued from time to time to Holders of Restricted ADSs, which legends shall be in a form reasonably satisfactory to the Depositary and shall contain the specific circumstances under which the Restricted ADRs and the Restricted ADSs represented thereby may be transferred or the Restricted Shares withdrawn. Any Restricted ADSs shall be issued in book-entry form on the books of the Depositary with such restrictions, notations and blocks to ensure that such Restricted ADSs may not be delivered off the books of the Depositary through the Direct Registration System. The terms “deliver,” “execute,” “issue,” “register,” “surrender,” “transfer” or “cancel,” when used with respect to book-entry Restricted ADSs, shall refer to an entry or entries on the books of the Depositary.

The Depositary, the Company and each Holder of Restricted ADRs agrees that the following text of paragraph (1)(b) of the form of ADR shall not be applicable to persons depositing Restricted Shares against the issuance of Restricted ADSs: “, and (iv) such Shares (A) are not Restricted Securities unless at the time of deposit the requirements of paragraphs (c), (e), (f) and (h) of Rule 144 shall not apply and such Shares may be freely transferred and may otherwise be offered and sold freely in the United States or (B) have been registered under the Securities Act of 1933. To the extent the person depositing Shares is an “affiliate” of the Company as such term is defined in Rule 144, the person also represents and warrants that upon the sale of the ADSs, all of the provisions of Rule 144 which enable the Shares to be freely sold (in the form of ADSs) will be fully complied with, or the ADSs have been sold pursuant to an effective registration statement under the Securities Act of 1933 covering the resale of such ADSs and the Shares represented thereby, and in either case, as a result thereof, all of the ADSs issued in respect of such Shares will not be on the sale thereof, Restricted Securities.” In addition, the foregoing text shall not be applicable to Holders of Restricted ADSs unless and until each of following actions has been taken: (w) any applicable Legends and any stop-transfer instructions applicable to the Restricted ADSs on the Depositary’s records have been removed by the Depositary, (x) the Restricted ADSs and the Shares represented thereby have ceased to be Restricted Securities and the Restricted ADSs are treated by the Depositary on the same terms as the other ADSs issued and outstanding hereunder that are not Restricted ADSs, (y) the Depositary has moved the Shares represented by the Restricted ADSs to the general pool of Shares represented by the ADSs, and (z) the Depositary has taken all actions necessary to remove any distinctions, limitations and restrictions previously existing between the applicable Restricted ADSs and Restricted ADRs, respectively, on the one hand, and the other ADSs and ADRs that are not Restricted ADSs or Restricted ADRs, respectively, on the other hand, including, without limitation, by making the newly-unrestricted ADSs eligible for inclusion in the applicable book-entry settlement systems ((w), (x), (y) and (z), together, the “ Restriction Removal Actions ”).

6

At all times that the Restricted ADSs constitute Restricted Securities, and at all times before the Restriction Removal Actions are taken, the Holder thereof shall not offer, sell, pledge, distribute, dispose of or otherwise transfer such Restricted ADSs unless it shall have provided to the Depositary (a) a legal opinion of U.S. counsel, in form and substance, and from counsel, reasonably satisfactory to the Depositary, to the effect that (i) the Shares represented by the Restricted ADSs have been registered under the Securities Act of 1933 or (ii) such Restricted ADSs and the Shares represented thereby may be offered and sold without registration under the Securities Act of 1933 pursuant to an applicable exemption from the registration requirements thereof and (b) such other documentation as the Depositary may reasonably require. In the case of a transfer under clause (ii), the Restricted ADSs will continue to bear the Legends after such transfer and shall otherwise remain subject to the provisions of this Section 3(e).

If a Holder surrenders Restricted ADSs for cancellation and withdrawal of Deposited Securities, the Depositary shall cancel the surrendered Restricted ADSs and deliver Deposited Securities only upon receipt of a certification and agreement in such form as the Depositary may reasonably request, signed by or on behalf of the person or entity that will be the beneficial owner of the Deposited Securities upon withdrawal, or, at the Depositary’s election, an opinion of U.S. counsel reasonably acceptable to the Depositary covering such matters as the Depositary may reasonably request, as well as such other opinions and documentation as the Depositary may reasonably require.

All references in this Deposit Agreement to ADSs shall include any Restricted ADSs issued under this Section 3(e), and all references to ADRs or American Depositary Receipts shall include any Restricted ADRs evidencing Restricted ADSs. The ADR Register shall include American Depositary Receipts and Restricted ADRs that are noted with such restrictions, notations and blocks to ensure that such Restricted ADSs may not be delivered off the books of the Depositary through the Direct Registration System. To the extent that, in relation to any Restricted ADS, any term or provision of this Section 3(e) shall be inconsistent with any other terms or provisions of this Deposit Agreement, the terms and conditions of this Section 3(e) shall take precedence with respect to such Restricted ADS, only to the extent of such inconsistency, and shall to such extent govern the rights and obligations of the parties to this Deposit Agreement pertaining to such Restricted ADSs and the Shares represented thereby. References in this Deposit Agreement to the Direct Registration System and Direct Registration ADRs shall not be deemed to apply to the Restricted ADSs or Restricted ADRs. References in this Deposit Agreement to Restricted ADRs shall refer to any written confirmation of book-entry notation provided to the Holder of such Restricted ADSs.

7

If the Restricted ADRs and the Restricted ADSs represented thereby cease to be Restricted Securities, then upon the Depositary’s receipt of (1) an opinion of U.S. counsel reasonably acceptable to the Depositary covering such matters as the Depositary may reasonably request, (2) one or more opinions of Cayman Islands and ROC counsels reasonably acceptable to the Depositary covering such matters as the Depositary may reasonably request, (3) an instruction letter and agreement from the Holder of the Restricted ADRs covering such matters as the Depositary may reasonably require, (4) instructions from the Company to undertake the Restriction Removal Actions, (5) any certifications and other documentation specified in this Deposit Agreement or otherwise reasonably required by the Depositary and (6) compliance with any procedures established or otherwise required by the Depositary, the Depositary shall undertake the Restriction Removal Actions.

After receiving such notice from the Custodian, the Depositary, subject to this Deposit Agreement, shall properly issue at the Transfer Office, to or upon the order of any person named in such notice, an ADR or ADRs registered as requested and evidencing the aggregate ADSs to which such person is entitled.

5. Distributions on Deposited Securities . To the extent that the Depositary determines in its discretion that any distribution pursuant to paragraph (10) of the form of ADR ( Distributions on Deposited Securities ) is not practicable with respect to any Holder, the Depositary may make such distribution as it so deems practicable, including the distribution of foreign currency, securities or property (or appropriate documents evidencing the right to receive foreign currency, securities or property) or the retention thereof as Deposited Securities with respect to such Holder’s ADRs (without liability for interest thereon or the investment thereof).

6. Withdrawal of Deposited Securities. In connection with any surrender of an ADR for withdrawal of the Deposited Securities represented by the ADSs evidenced thereby, the Depositary may require proper endorsement in blank of such ADR (or duly executed instruments of transfer thereof in blank) and the Holder’s written order directing the Depositary to cause the Deposited Securities represented by the ADSs evidenced by such ADR to be withdrawn and delivered to, or upon the written order of, any person designated in such order (a “ Withdrawal Order ”). Directions from the Depositary to the Custodian to deliver Deposited Securities shall be given by letter, first class airmail postage prepaid, or, at the request, risk and expense of the Holder, by SWIFT, cable, telex or facsimile transmission. Delivery of Deposited Securities may be made by the delivery of certificates (which, if required by law shall be properly endorsed or accompanied by properly executed instruments of transfer or, if such certificates may be registered, registered in the name of such Holder or as ordered by such Holder in any Withdrawal Order) or by such other means as the Depositary may

8

deem practicable, including, without limitation, by transfer of record ownership thereof to an account designated in the Withdrawal Order maintained either by the Company or an accredited intermediary, such as a bank, stock administration agent or depositary or clearing corporation, acting as a registrar for the Deposited Securities.

7. Substitution of ADRs . The Depositary shall execute and deliver a new Direct Registration ADR in exchange and substitution for any mutilated certificated ADR upon cancellation thereof or in lieu of and in substitution for such destroyed, lost or stolen certificated ADR, unless the Depositary has notice that such ADR has been acquired by a bona fide purchaser, upon the Holder thereof filing with the Depositary a request for such execution and delivery and a sufficient indemnity bond and satisfying any other reasonable requirements imposed by the Depositary.

JPMORGAN CHASE BANK, N.A., a national banking association organized under the laws of the United States of America, as depositary hereunder (the “ Depositary ”), hereby certifies that                                               is the registered owner (a “ Holder ”) of                              American Depositary Shares (“ ADSs ”), each (subject to paragraph (13) ( Changes Affecting Deposited Securities )) representing five (5) ordinary shares (including the rights to receive Shares described in paragraph (1) ( Issuance of ADSs ), “ Shares ” and, together with any other securities, cash or property from time to time held by the Depositary in respect or in lieu of deposited Shares, the “ Deposited Securities ”), of ASLAN Pharmaceuticals Limited, an exempted company organized under

A-1

the laws of the Cayman Islands (the “ Company ”), deposited under the Deposit Agreement, dated as of                      , 2018 (as amended from time to time, the “ Deposit Agreement ”), among the Company, the Depositary and all Holders from time to time of American Depositary Receipts issued thereunder (“ ADRs ”), each of whom by accepting an ADR becomes a party thereto. The Deposit Agreement and this ADR (which includes the provisions set forth on the reverse hereof) shall be governed by and construed in accordance with the internal laws of the State of New York without giving effect to the application of the conflict of law principles thereof. All capitalized terms used herein, and not defined herein, shall have the meanings ascribed to such terms in the Deposit Agreement.

(1) Issuance of ADSs .

(a) Issuance . This ADR is one of the ADRs issued under the Deposit Agreement. Subject to the other provisions hereof, the Depositary may so issue ADRs for delivery at the Transfer Office (as hereinafter defined) only against deposit of: (i) Shares in a form satisfactory to the Custodian; or (ii) rights to receive Shares from the Company or any registrar, transfer agent, clearing agent or other entity recording Share ownership or transactions.

(b) Representations and Warranties of Depositors . Every person depositing Shares under the Deposit Agreement represents and warrants that: (i) such Shares and the certificates therefor are duly authorized, validly issued and outstanding, fully paid, nonassessable and legally obtained by such person, (ii) all pre-emptive and comparable rights, if any, with respect to such Shares have been validly waived or exercised, (iii) the person making such deposit is duly authorized so to do, (iv) the Shares presented for deposit are free and clear of any lien, encumbrance, security interest, charge, mortgage or adverse claim, and (v) except for persons depositing Restricted Shares against the issuance of Restricted ADSs as contemplated by, and in accordance with, Section 3(e) of the Deposit Agreement, such Shares (A) are not Restricted Securities unless at the time of deposit the requirements of paragraphs (c), (e), (f) and (h) of Rule 144 shall not apply and such Shares may be freely transferred and may otherwise be offered and sold freely in the United States or (B) have been registered under the Securities Act of 1933. Except for persons depositing Restricted Shares against the issuance of Restricted ADSs as contemplated by, and in accordance with, Section 3(e) of the Deposit Agreement, to the extent the person depositing Shares is an “affiliate” of the Company as such term is defined in Rule 144, the person also represents and warrants that upon the sale of the ADSs, all of the provisions of Rule 144 which enable the Shares to be freely sold (in the form of ADSs) will be fully complied with, or the ADSs have been sold pursuant to an effective registration statement under the Securities Act of 1933 covering the resale of such ADSs and the Shares represented thereby, and in either case, as a result thereof, all of the ADSs issued in respect of such Shares will not

A-2

be on the sale thereof, Restricted Securities. Such representations and warranties shall survive the deposit and withdrawal of Shares and the issuance and cancellation of ADSs in respect thereof and the transfer of such ADSs. The Depositary may refuse to accept for such deposit any Shares identified by the Company in order to facilitate compliance with the requirements of the securities laws, rules and regulations in the United States, including the Securities Act of 1933.

(c) Restricted American Depositary Shares . The Depositary may from time to time, at the written request and expense of the Company, establish procedures enabling the deposit under the Deposit Agreement of Shares that are Restricted Securities in order to enable the Depositary to issue Restricted ADRs representing such deposited Shares (such Shares that are Restricted Securities being “ Restricted Shares ” and the ADRs evidencing such Restricted ADSs being “ Restricted ADRs ”). The Company shall assist the Depositary in the establishment of such procedures and agrees that it shall take all steps necessary and reasonably satisfactory to the Depositary to ensure that the establishment of such procedures does not violate the provisions of the Securities Act of 1933 or any other applicable laws. The depositors of such Restricted Shares and the holders of the Restricted ADSs may be required prior to the deposit of such Restricted Shares, the transfer of the Restricted ADRs and the Restricted ADSs evidenced thereby or the withdrawal of the Restricted Shares represented by Restricted ADSs to provide such written certifications, opinions of counsel and/or agreements as the Depositary or the Company may require. The Company shall provide to the Depositary in writing the legend(s) (the “ Legends ”) to be included in the account statements issued from time to time to Holders of Restricted ADSs, which legends shall be in a form reasonably satisfactory to the Depositary and shall contain the specific circumstances under which the Restricted ADRs and the Restricted ADSs represented thereby may be transferred or the Restricted Shares withdrawn. Any Restricted ADSs shall be issued in book-entry form on the books of the Depositary with such restrictions, notations and blocks to ensure that such Restricted ADSs may not be delivered off the books of the Depositary through the Direct Registration System. The terms “deliver,” “execute,” “issue,” “register,” “surrender,” “transfer” or “cancel,” when used with respect to book-entry Restricted ADSs, shall refer to an entry or entries on the books of the Depositary.

The Depositary, the Company and each Holder of Restricted ADRs agrees that the following text of paragraph (1)(b) of the form of ADR shall not be applicable to persons depositing Restricted Shares against the issuance of Restricted ADSs: “, and (iv) such Shares (A) are not Restricted Securities unless at the time of deposit the requirements of paragraphs (c), (e), (f) and (h) of Rule 144 shall not apply and such Shares may be freely transferred and may otherwise be offered and sold freely in the United States or (B) have been registered under the Securities Act of 1933. To the extent the person depositing Shares is an “affiliate” of the Company as such term is defined in

A-3

Rule 144, the person also represents and warrants that upon the sale of the ADSs, all of the provisions of Rule 144 which enable the Shares to be freely sold (in the form of ADSs) will be fully complied with, or the ADSs have been sold pursuant to an effective registration statement under the Securities Act of 1933 covering the resale of such ADSs and the Shares represented thereby, and in either case, as a result thereof, all of the ADSs issued in respect of such Shares will not be on the sale thereof, Restricted Securities.” In addition, the foregoing text shall not be applicable to Holders of Restricted ADSs unless and until each of following actions has been taken: (w) any applicable Legends and any stop-transfer instructions applicable to the Restricted ADSs on the Depositary’s records have been removed by the Depositary, (x) the Restricted ADSs and the Shares represented thereby have ceased to be Restricted Securities and the Restricted ADSs are treated by the Depositary on the same terms as the other ADSs issued and outstanding under the Deposit Agreement that are not Restricted ADSs, (y) the Depositary has moved the Shares represented by the Restricted ADSs to the general pool of Shares represented by the ADSs, and (z) the Depositary has taken all actions necessary to remove any distinctions, limitations and restrictions previously existing between the applicable Restricted ADSs and Restricted ADRs, respectively, on the one hand, and the other ADSs and ADRs that are not Restricted ADSs or Restricted ADRs, respectively, on the other hand, including, without limitation, by making the newly-unrestricted ADSs eligible for inclusion in the applicable book-entry settlement systems ((w), (x), (y) and (z), together, the “ Restriction Removal Actions ”).

At all times that the Restricted ADSs constitute Restricted Securities, and at all times before the Restriction Removal Actions are taken, the Holder thereof shall not offer, sell, pledge, distribute, dispose of or otherwise transfer such Restricted ADSs unless it shall have provided to the Depositary (a) a legal opinion of U.S. counsel, in form and substance, and from counsel, reasonably satisfactory to the Depositary, to the effect that (i) the Shares represented by the Restricted ADSs have been registered under the Securities Act of 1933 or (ii) such Restricted ADSs and the Shares represented thereby may be offered and sold without registration under the Securities Act of 1933 pursuant to an applicable exemption from the registration requirements thereof and (b) such other documentation as the Depositary may reasonably require. In the case of a transfer under clause (ii), the Restricted ADSs will continue to bear the Legends after such transfer and shall otherwise remain subject to the provisions of this Section 3(e) of the Deposit Agreement.

If a Holder surrenders Restricted ADSs for cancellation and withdrawal of Deposited Securities, the Depositary shall cancel the surrendered Restricted ADSs and deliver Deposited Securities only upon receipt of a certification and agreement in such form as the Depositary may reasonably request, signed by or on behalf of the person or entity that will be the beneficial owner of the Deposited Securities upon withdrawal, or, at the Depositary’s election, an opinion of U.S. counsel reasonably acceptable to the Depositary covering such matters as the Depositary may reasonably request, as well as such other opinions and documentation as the Depositary may reasonably require.

A-4

All references in the Deposit Agreement to ADSs shall include any Restricted ADSs issued under this Section 3(e), and all references to ADRs or American Depositary Receipts shall include any Restricted ADRs evidencing Restricted ADSs. The ADR Register shall include American Depositary Receipts and Restricted ADRs that are noted with such restrictions, notations and blocks to ensure that such Restricted ADSs may not be delivered off the books of the Depositary through the Direct Registration System. To the extent that, in relation to any Restricted ADS, any term or provision of Section 3(e) of the Deposit Agreement shall be inconsistent with any other terms or provisions of the Deposit Agreement, the terms and conditions of Section 3(e) of the Deposit Agreement shall take precedence with respect to such Restricted ADS, only to the extent of such inconsistency, and shall to such extent govern the rights and obligations of the parties to the Deposit Agreement pertaining to such Restricted ADSs and the Shares represented thereby. References in the Deposit Agreement to the Direct Registration System and Direct Registration ADRs shall not be deemed to apply to the Restricted ADSs or Restricted ADRs. References in the Deposit Agreement to Restricted ADRs shall refer to any written confirmation of book-entry notation provided to the Holder of such Restricted ADSs.

If the Restricted ADRs and the Restricted ADSs represented thereby cease to be Restricted Securities, then upon the Depositary’s receipt of (1) an opinion of U.S. counsel reasonably acceptable to the Depositary covering such matters as the Depositary may reasonably request, (2) one or more opinions of Cayman Islands and ROC counsels reasonably acceptable to the Depositary covering such matters as the Depositary may reasonably request, (3) an instruction letter and agreement from the Holder of the Restricted ADRs covering such matters as the Depositary may reasonably require, (4) instructions from the Company to undertake the Restriction Removal Actions, (5) any certifications and other documentation specified in the Deposit Agreement or otherwise reasonably required by the Depositary and (6) compliance with any procedures established or otherwise required by the Depositary, the Depositary shall undertake the Restriction Removal Actions.

(2) Withdrawal of Deposited Securities . Beginning on the fifth (5 ^th ) ROC business day following the date of initial issuance of the ADSs or such later date as the Depositary may announce, subject to the approval from the Taipei Exchange, any necessary ROC approvals and the provisions under the Deposit Agreement, Holders are entitled to withdraw and sell the underlying Shares.

A-5

In accordance herewith and subject to the requirements of the laws of the Cayman Islands and the ROC, a Holder may request the Depositary to withdraw from the depositary receipt facility created by the Deposit Agreement the Shares represented by such Holder’s ADRs and transfer such Shares to such Holder or, upon the written order of any person designated in such Withdrawal Order, upon surrender of (a) a certificated ADR in a form satisfactory to the Depositary at the Transfer Office or (b) proper instructions and documentation in the case of a Direct Registration ADR, as the case may be, in each case upon payment of any fees, expenses, taxes or governmental charges as provided in the Deposit Agreement, delivery to the Depositary of any documentation, certifications or information which may be required in order to comply with the laws, rules or regulations of the Cayman Islands and the ROC, and subject to the terms of the Deposit Agreement and paragraphs (4) and (5) hereof), provided that the Company has delivered to the Custodian the Shares in physical certificate form or scripless form to be sold or so delivered.

The Company has advised the Depositary that, under current ROC law, a Holder who is a non-ROC person wishing to withdraw and hold deposited Shares from the ADR facility is required to appoint an eligible agent in the ROC for filing tax returns and making tax payments (a “Tax Guarantor”). Such Tax Guarantor will be required to meet the qualifications set by the Ministry of Finance of the ROC and will act as the guarantor of the withdrawing Holder’s tax payment obligations. In addition, subject to certain limited exceptions, under current ROC law, repatriation of profits by a non-ROC withdrawing Holder is subject to the submission of evidence by the withdrawing Holder of the appointment of a Tax Guarantor to, and approval thereof by, the tax authority and tax clearance certificates or evidentiary document issued by the Tax Guarantor. There can be no assurance that a withdrawing Holder will be able to appoint and obtain approval for such agent in a timely manner or at all.

The Company has also advised the Depositary that, under current ROC law, a Holder who is not an ROC resident or ROC company wishing to present ADSs to the Depositary for cancellation and withdrawal and holding of the Deposited Securities from the depositary receipt facility is required to register as a foreign investor with the TWSE, if the Holder has never registered as foreign investor with the TWSE previously, for making investments in the ROC securities market prior to withdrawing and holding the Deposited Securities from the depositary receipts facility.

The Company has also advised the Depositary and the Holders that under current ROC law, such withdrawing Holder is required to appoint a local agent in the ROC to, among other things, open a securities trading account with prior approval granted by the TWSE with a local securities brokerage firm (with qualification set by the ROC FSC) and a bank account, pay ROC taxes, remit funds, exercise shareholder rights and perform such other functions as the Holder may designate upon such withdrawal. In addition, such withdrawing Holder is also required to appoint a custodian bank and open a custodian account to hold the securities and cash in safekeeping, make confirmations,

A-6

settle trades and report all relevant information. Without making such appointment and the opening of such custodian account, the withdrawing Holder would be unable to hold or subsequently sell the deposited Shares withdrawn from the ADR facility on the Taipei Exchange. The laws of the ROC applicable to the withdrawal of Deposited Securities may change from time to time. There can be no assurances that current law will remain in effect or that future changes of ROC law will not adversely affect the ability of Holders to withdraw deposited Shares hereunder.

Currently, a party who is a People’s Republic of China (“PRC”) person may not withdraw and hold the underlying Shares unless it is a qualified domestic institutional investor (“ QDII ”) in the PRC or has obtained the investment approval from the Investment Commission, Ministry of Economic Affairs, Executive Yuan of the ROC. However, it is unclear whether a QDII may freely withdraw and hold the underlying Shares if the business of the issuer of the underlying Shares is not within the list of industries open to PRC investment as promulgated by the ROC government. Further, there is no assurance that in the future, there will not be further restrictions or prohibitions imposed on PRC persons (including QDIIs) from investing in certain industries in the ROC, which might accordingly cause a party who is a PRC person to be unable to withdraw and hold the underlying Shares. Under current ROC law, a PRC person means an individual holding a passport issued by the PRC, a resident of any area of China under the effective control or jurisdiction of the PRC (but not including a special administrative region of the PRC such as Hong Kong or Macau, if so excluded by applicable laws of the ROC), any legal person, group, or other institutions of the PRC and any corporation and other entity organized in countries outside of the ROC or PRC that is directly or indirectly controlled by or directly or indirectly has more than 30% of its capital beneficially owned by any PRC person described above.

In connection with any surrender of a ADR for withdrawal and the delivery of the Deposited Securities represented by the ADSs evidenced thereby, the Depositary may require proper endorsement in blank of such ADR (or duly executed instruments of transfer thereof in blank) and the Holder’s written order (a “ Withdrawal Order ”) directing the Depositary to cause the Deposited Securities represented by the ADSs evidenced by such ADR to be withdrawn and delivered to, or upon the written order of, any person designated in such order. Directions from the Depositary to the Custodian in connection with the withdrawal or delivery of the Deposited Securities shall be given by letter, first class airmail postage prepaid, or, at the request, risk and expense of the Holder, by SWIFT, cable, telex or facsimile transmission.

In the case of a Holder requesting the delivery of the Deposited Securities represented by the ADSs evidenced by the Holder’s ADRs so surrendered, subject to applicable ROC law and to the other provisions hereof, at the request, risk and expense of the Holder hereof, the Depositary may deliver such Deposited Securities at such other

A-7

place as may have been requested by the Holder. Delivery of Deposited Securities may be made by the delivery of certificates (which, if required by law shall be properly endorsed or accompanied by properly executed instruments of transfer or, if such certificates may be registered, registered in the name of such Holder or as ordered by such Holder in any Withdrawal Order) or by such other means as the Depositary may deem practicable.

Notwithstanding any other provision of the Deposit Agreement or this ADR, the withdrawal of Deposited Securities may be restricted only for the reasons set forth in General Instruction I.A.(1) of Form F-6 (as such instructions may be amended from time to time) under the Securities Act of 1933. The immediately foregoing sentence shall not apply to Deposited Securities that are Restricted Securities.

(3) Transfers, Split-Ups and Combinations of ADRs . The Depositary or its agent will keep, at a designated transfer office (the “ Transfer Office ”), (a) a register (the “ ADR Register ”) for the registration, registration of transfer, combination and split-up of ADRs, and, in the case of Direct Registration ADRs, shall include the Direct Registration System, which at all reasonable times will be open for inspection by Holders and the Company for the purpose of communicating with Holders in the interest of the business of the Company or a matter relating to the Deposit Agreement and (b) facilities for the delivery and receipt of ADRs. The term ADR Register includes the Direct Registration System. Title to this ADR (and to the Deposited Securities represented by the ADSs evidenced hereby), when properly endorsed (in the case of ADRs in certificated form) or upon delivery to the Depositary of proper instruments of transfer, is transferable by delivery with the same effect as in the case of negotiable instruments under the laws of the State of New York; provided that the Depositary, notwithstanding any notice to the contrary, may treat the person in whose name this ADR is registered on the ADR Register as the absolute owner hereof for all purposes and neither the Depositary nor the Company will have any obligation or be subject to any liability under the Deposit Agreement to any holder of an ADR, unless such holder is the Holder thereof. Subject to paragraphs (4) and (5), this ADR is transferable on the ADR Register and may be split into other ADRs or combined with other ADRs into one ADR, evidencing the aggregate number of ADSs surrendered for split-up or combination, by the Holder hereof or by duly authorized attorney upon surrender of this ADR at the Transfer Office properly endorsed (in the case of ADRs in certificated form) or upon delivery to the Depositary of proper instruments of transfer and duly stamped as may be required by applicable law; provided that the Depositary may close the ADR Register at any time or from time to time when deemed expedient by it. At the request of a Holder, the Depositary shall, for the purpose of substituting a certificated ADR with a Direct Registration ADR, or vice versa, execute and deliver a certificated ADR or a Direct Registration ADR, as the case may be, for any authorized number of ADSs requested, evidencing the same aggregate number of ADSs as those evidenced by the certificated ADR or Direct Registration ADR, as the case may be, substituted.

(4) Certain Limitations to Registration, Transfer etc. Prior to the issue, registration, registration of transfer, split-up or combination of any ADR, the delivery of any distribution in respect thereof, or, subject to the penultimate sentence of paragraph (2) ( Withdrawal of Deposited Securities ), the withdrawal of any Deposited Securities, and from time to time in the case of clause (b)(ii) of this paragraph (4), the Company, the Depositary or the Custodian may require: (a) payment with respect thereto of (i) any stock transfer or other tax or other governmental charge, (ii) any stock transfer or registration fees in effect for the registration of transfers of Shares or other Deposited Securities upon any applicable register, and (iii) any applicable charges as provided in paragraph (7) ( Charges of Depositary ) of this ADR; (b) the production of proof satisfactory to it of (i) the identity of any signatory and genuineness of any signature and (ii) such other information, including without limitation, information as to citizenship, residence, exchange control approval, beneficial or other ownership of, or interest in, any securities, compliance with applicable law, regulations, provisions of or governing Deposited Securities and terms of the Deposit Agreement and this ADR, as it may deem necessary or proper; and (c) compliance with such regulations as the Depositary may establish consistent with the Deposit Agreement.

The issuance of ADRs, the acceptance of deposits of Shares, the registration, registration of transfer, split-up or combination of ADRs or, subject to the penultimate sentence of paragraph (2) ( Withdrawal of Deposited Securities ), the withdrawal of Deposited Securities may be suspended, generally or in particular instances, when the ADR Register or any register for Deposited Securities is closed or when any such action is deemed advisable by the Depositary.

(5) Liability of Holder for Taxes, Duties and Other Charges . If any tax or other governmental charges (including any penalties and/or interest) shall become payable by or on behalf of the Custodian or the Depositary with respect to this ADR, any Deposited Securities represented by the ADSs evidenced hereby or any distribution thereon, such tax or other governmental charge shall be paid by the Holder hereof to the Depositary and by holding or having held an ADR the Holder and all prior Holders hereof, jointly and severally, agree to indemnify, defend and save harmless each of the Depositary and its agents in respect thereof. The Depositary may refuse to effect any registration, registration of transfer, split-up or combination hereof or, subject to the penultimate sentence of paragraph (2) ( Withdrawal of Deposited Securities ), any withdrawal of such Deposited Securities until such payment is made. The Depositary may also deduct from any distributions on or in respect of Deposited Securities, or may sell by public or private sale for the account of the Holder hereof any part or all of such Deposited Securities, and may apply such deduction or the proceeds of any such sale in

A-9

payment of such tax or other governmental charge, the Holder hereof remaining liable for any deficiency, and shall reduce the number of ADSs evidenced hereby to reflect any such sales of Shares. Notwithstanding the foregoing, the Company will pay all stamp duties and other similar duties or taxes payable in the Cayman Islands, the ROC, the United States of America and any other jurisdiction, on or in connection with the constitution and issue of the ADSs and the execution or other event concerning the Deposit Agreement. If any legal proceedings are taken to enforce the obligations of the Company under the Deposit Agreement or the ADSs (including the certificates evidencing such ADSs) and for the purpose of such proceedings any of them are required to be taken into or enforced in any jurisdiction and stamp duties or other similar duties or taxes become payable in connection with such proceedings in such jurisdiction, the Holders will forthwith pay (or reimburse the person making a valid payment of) all such stamp duties and other similar duties and taxes, including penalties and interest (if any) unless otherwise ordered by a court of competent jurisdiction in such proceedings. The Depositary may sell any Deposited Securities and cancel ADSs with respect thereof in order to pay any such stamp duties or other similar duties or taxes owed hereunder by Holders without the Depositary being required to request payment thereof from Holders. In connection with any distribution to Holders, (a) the Company will remit to the appropriate governmental authority or agency all amounts (if any) required to be withheld and owing to such authority or agency by the Company, and, if the Company determines that any taxes are not required to be withheld with respect to any Holder or Holders, it shall so advise the Depositary and instruct the Depositary in writing to pay such distribution to such Holder(s) without withholding the relevant taxes (but subject to all other deductions provided for in the Deposit Agreement); and (b) the Depositary and the Custodian will remit to the appropriate governmental authority or agency all amounts (if any) required to be withheld and owing to such authority or agency by the Depositary or the Custodian. The Depositary will forward to the Company such information from its transfer records maintained by it in its capacity as Depositary under the Deposit Agreement as the Company may reasonably request to enable the Company to file any necessary reports with governmental authorities or agencies. If the Depositary determines that any distribution in property other than cash (including Shares or rights) on Deposited Securities is subject to any tax that the Depositary or the Custodian is obligated to withhold, the Depositary may dispose of all or a portion of such property in such amounts and in such manner as the Depositary deems necessary and practicable to pay such taxes, by public or private sale, and the Depositary shall distribute the net proceeds of any such sale or the balance of any such property after deduction of such taxes to the Holders entitled thereto. The Company shall, as soon as practicable after the due date for any payment to the government

A-10

of the Cayman Islands or the ROC of any tax or other governmental charge with respect to any distribution with respect to Deposited Securities, provide the Depositary with an official receipt from the Cayman Islands or the ROC (or certified copies thereof), as the case may be, setting forth the amounts, if any, of tax or other government charge so paid to the government of the Cayman Islands or the ROC, as the case may be. The Depositary shall provide a copy of such receipt, or other documentation, to the Holder of the ADRs representing such Deposited Securities at the time of such distribution upon the request made by the Holder thereof to the Depositary. The Depositary shall elect to waive any and all deferral of income tax on Share Distributions received hereunder. Each Holder of an ADR or an interest therein agrees to indemnify the Depositary, the Company, the Custodian and any of their respective officers, directors, employees, agents and affiliates against, and hold each of them harmless from, any claims by any governmental authority with respect to taxes, additions to tax, penalties or interest arising out of any refund of taxes, reduced rate of withholding at source or other tax benefit obtained which obligations shall survive any transfer or surrender of ADSs or the termination of the Deposit Agreement.

(6) Disclosure of Interests .

(a) General . To the extent that the provisions of or governing any Deposited Securities, the laws, rules or regulations of the Cayman Islands, the ROC, the Taipei Exchange or the Company’s Memorandum and Articles of Association may require disclosure of or impose limits on beneficial or other ownership of, or interest in, Deposited Securities, other Shares and other securities and may provide for blocking transfer, voting or other rights to enforce such disclosure or limits, Holders and all persons holding ADRs agree to comply with all such disclosure requirements and ownership limitations and to comply with any reasonable Company instructions in respect thereof.

(b) Jurisdiction Specific. The Company may have certain disclosure obligations and reporting obligations under ROC laws and regulations if (a) the person to be registered as a shareholder of Shares withdrawn under the Deposit Agreement is a “related party” of the Company under its regulations governing the preparation of its financial reports and the International Financial Reporting Standards; or (b) the cumulative number of Shares withdrawn by the person exceeds 10% of the Shares represented by the ADSs originally issued under the Deposit Agreement. Due to these obligations, the Depositary may ask the withdrawing Holder to disclose the name of the beneficial owner of the ADSs delivered for cancellation and to provide proof of identity and genuineness of any signature and other information and documents before the withdrawing Holder may cancel its ADSs. The withdrawal of Shares may be delayed until the Depositary receives such information, the proof so requested and satisfactory evidence of the withdrawing Holder’s compliance with all laws and regulations. The information that a withdrawing Holder is required to provide may include the name and nationality of the beneficial owner, the number of Shares or individual certificates of payment the beneficial owner is withdrawing or has withdrawn in the past and whether certain affiliations exist between the beneficial owner and the Company.

A-11

Notwithstanding any other provision hereof, each Holder agrees to comply with requests from the Company pursuant to the laws, rules and regulations of the Cayman Islands and the ROC as well as the rules and regulations of any stock exchange on which the Shares are, or will be, registered, traded or listed to provide information, inter alia, as to the capacity in which such Holder owns ADRs (and Shares as the case may be) and regarding the identity of any other person interested in such ADRs and the nature of such interest, and the Depositary agrees to mail to Holders reasonable requests prepared by and from the Company with respect to requests for such information and, to the extent a response is received by the Depositary, to forward to the Company any such responses.

A-18

To the extent the Depositary has been provided with at least 45 days’ notice of the proposed meeting, if such instructions are not so timely received by the Depositary from any Holder, such Holder shall be deemed, and the Depositary is instructed to deem such Holder, to have instructed the Depositary to give a discretionary proxy to a person designated by the Company to vote the Deposited Securities represented by the American Depositary Shares evidenced by such Holder’s ADRs as to which such instructions are so given, provided that no such instruction shall be deemed given and no discretionary proxy shall be given (a) if the Company informs the Depositary in writing (and the Company agrees to provide the Depositary with such information promptly in writing) that (i) it does not wish such proxy to be given, (ii) substantial opposition exists with respect to any agenda item for which the proxy would be given or (iii) the agenda item in question, if approved, would materially or adversely affect the rights of holders of Shares and (b) unless, with respect to such meeting, the Depositary has been provided with an opinion of Caymans Islands and ROC counsel to the Company, in form and substance satisfactory to the Depositary, to the effect that (a) the granting of such discretionary proxy does not subject the Depositary to any reporting obligations in the Cayman Islands or the ROC, or by the FSC or the Taipei Exchange, (b) the granting of such proxy will not result in a violation of the laws, rules, regulations or permits of the Cayman Islands, the ROC, the FSC or the Taipei Exchange (c) the voting arrangement and deemed instruction as contemplated herein will be given effect under the laws, rules, regulations and permits of the Cayman Islands, the ROC, the FSC and the Taipei Exchange and (d) the granting of such proxy will not under any circumstances result in the Depositary being treated as the beneficial owner of the Shares represented by the ADRs under the laws, rules, regulations or permits of the Cayman Islands, the ROC, the FSC or the Taipei Exchange. There is no guarantee that Holders generally or any Holder in particular will receive the notice described above with sufficient time to enable such Holder to return any voting instructions to the Depositary in a timely manner.

In accordance with the Memorandum and Articles of Association of the Company, a shareholder of the Company may not exercise its own vote or by proxy on behalf of another shareholder of the Company in respect of any contract or proposed contract or arrangement if such shareholder may be interested therein. Accordingly, no Holder shall instruct the Depositary to vote on its behalf on any matter to be considered at the relevant meeting in respect of which such Holder is interested.

None of the Depositary, the Custodian or the Company, or any of their respective directors, officers, employees, agents and/or affiliates, shall incur any liability for any tax consequences that may be incurred by Holders and beneficial owners of, or other holders of interests in, ADSs or ADRs on account of their ownership of the ADSs or ADRs. The Depositary shall not incur any liability for the content of any information submitted to it by or on behalf of the Company for distribution to the Holders or for any inaccuracy of any translation thereof, for any investment risk associated with acquiring an interest in the Deposited Securities, for the validity or worth of the Deposited Securities, for the credit-worthiness of any third party, for allowing any rights to lapse upon the terms of the Deposit Agreement or for the failure or timeliness of any notice from the Company. 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 any matter arising wholly after the removal or resignation of the Depositary. The Company has agreed to indemnify the Depositary and its agents under certain circumstances and the Depositary has agreed to indemnify the Company under certain circumstances. Neither the Depositary, the Company, nor any of their respective agents shall be liable to Holders or beneficial owners of, or holders of interests in, ADSs or ADRs for any indirect, special, punitive or consequential damages or lost profits, or any fees or expenses of counsel in connection therewith, in each case of any form incurred by any person or entity, whether or not foreseeable and regardless of the type of action in which such a claim may be brought. No disclaimer of liability under the Securities Act of 1933 is intended by any provision hereof.

(15) Resignation and Removal of Depositary; the Custodian .

(a) Resignation . The Depositary may resign as Depositary by written notice of its election to do so delivered to the Company, such resignation to take effect upon the appointment of a successor depositary and its acceptance of such appointment as provided in the Deposit Agreement.

A-22

(b) Removal . The Depositary may at any time be removed by the Company by no less than 60 days prior written notice of such removal, to become effective upon the later of (i) the 60th day after delivery of the notice to the Depositary and (ii) the appointment of a successor depositary and its acceptance of such appointment as provided in the Deposit Agreement.

(c) The Custodian . The Depositary may appoint substitute or additional Custodians and the term “ Custodian ” refers to each Custodian or all Custodians as the context requires.

(16) Amendment . Subject to the penultimate sentence of paragraph (2) ( Withdrawal of Deposited Securities ), the ADRs and the Deposit Agreement may be amended by the Company and the Depositary, provided that any amendment that imposes or increases any fees or charges (other than stock transfer or other taxes and other governmental charges, transfer or registration fees, SWIFT, cable, telex or facsimile transmission costs, delivery costs or other such expenses), or that shall otherwise prejudice any substantial existing right of Holders, shall become effective 30 days after notice of such amendment shall have been given to the Holders. Every Holder of an ADR at the time any amendment to the Deposit Agreement or form of ADRs so becomes effective shall be deemed, by continuing to hold such ADR, to consent and agree to such amendment and to be bound by the Deposit Agreement as amended thereby. In no event shall any amendment impair the right of the Holder of any ADR to surrender such ADR and receive the Deposited Securities represented thereby, except in order to comply with mandatory provisions of applicable law. Any amendments or supplements which (i) are reasonably necessary (as agreed by the Company and the Depositary) in order for (a) the ADSs to be registered on Form F-6 under the Securities Act of 1933 or (b) the ADSs or Shares to be traded solely in electronic book-entry form and (ii) do not in either such case impose or increase any fees or charges to be borne by Holders, shall be deemed not to prejudice any substantial rights of Holders. Notwithstanding the foregoing, if any governmental body or regulatory body should adopt new laws, rules or regulations which would require amendment or supplement of the Deposit Agreement or the form of ADR to ensure compliance therewith, the Company and the Depositary may amend or supplement the Deposit Agreement and the ADR at any time in accordance with such changed laws, rules or regulations. Such amendment or supplement to the Deposit Agreement or form of ADRs in such circumstances may become effective before a notice of such amendment or supplement is given to Holders or within any other period of time as required for compliance. Notice of any amendment to the Deposit Agreement or form of ADRs shall not need to describe in detail the specific amendments effectuated thereby, and

A-23

failure to describe the specific amendments in any such notice shall not render such notice invalid, provided, however, that, in each such case, the notice given to the Holders identifies a means for Holders to retrieve or receive the text of such amendment (i.e., upon retrieval from the Commission’s, the Depositary’s or the Company’s website or upon request from the Depositary).

(17) Termination . The Depositary may, and shall at the written direction of the Company, terminate the Deposit Agreement and this ADR by mailing notice of such termination to the Company and the Holders at least 30 days prior to the date fixed in such notice for such termination; provided, however, if the Depositary shall have (i) resigned as Depositary hereunder, notice of such termination by the Depositary shall not be provided to Holders unless a successor depositary shall not be operating hereunder within 60 days of the date of such resignation, or (ii) been removed as Depositary hereunder, notice of such termination by the Depositary shall not be provided to Holders unless a successor depositary shall not be operating hereunder on the 60 ^th day after the Company’s notice of removal was first provided to the Depositary. Notwithstanding anything to the contrary herein, the Depositary may terminate the Deposit Agreement subject to giving 30 days’ notice to the Company and the Holders, under the following circumstances: (i) in the event of the Company’s bankruptcy or insolvency, (ii) if the Company’s shares are de-listed, (iii) if the Company effects (or will effect) a redemption of all or substantially all of the Deposited Securities, or a cash or share distribution representing a return of all or substantially all of the value of the Deposited Securities, or (iv) there occurs a merger, consolidation, sale of all or substantially all assets or other transaction as a result of which securities or other property are delivered in exchange for or in lieu of Deposited Securities.

After the date so fixed for termination, the Depositary and its agents will perform no further acts under the Deposit Agreement and this ADR, except to receive and hold (or sell) distributions on Deposited Securities and deliver Deposited Securities being withdrawn. As soon as practicable after the date so fixed for termination, the Depositary shall use its reasonable efforts to sell the Deposited Securities and shall thereafter (as long as it may lawfully do so) hold in an account (which may be a segregated or unsegregated account) the net proceeds of such sales, together with any other cash then held by it under the Deposit Agreement, without liability for interest, in trust for the pro rata benefit of the Holders of ADRs not theretofore surrendered. After making such sale, the Depositary shall be discharged from all obligations in respect of the Deposit Agreement and this ADR, except to account for such net proceeds and other cash. After the date so fixed for termination, the Company shall be discharged from all obligations under the Deposit Agreement except for its obligations to the Depositary and its agents.

A-24

(18) Appointment. Each Holder and each owner and person holding an interest in ADSs or ADRs, upon acceptance of any ADSs or ADRs (or any interest therein) issued in accordance with the terms and conditions of the Deposit Agreement shall be deemed for all purposes to (a) be a party to and bound by the terms of the Deposit Agreement and the applicable ADR(s), and (b) appoint the Depositary its attorney-in-fact, with full power to delegate, to act on its behalf and to take any and all actions contemplated in the Deposit Agreement and the applicable ADR(s), to adopt any and all procedures necessary to comply with applicable law and to take such action as the Depositary in its sole discretion may deem necessary or appropriate to carry out the purposes of the Deposit Agreement and the applicable ADR(s), the taking of such actions to be the conclusive determinant of the necessity and appropriateness thereof.

(19) Waiver .

(20) Jurisdiction. By holding an ADS or an interest therein, Holders and owners of interests in ADSs each irrevocably agree that any legal suit, action or proceeding against or involving Holders or owners of interests in ADSs brought by the Company or the Depositary, arising out of or based upon the Deposit Agreement, the ADSs or the ADRs or the transactions contemplated thereby or hereby, may be instituted in a state or federal court in New York, New York, and by holding an ADS or an interest therein each irrevocably waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding.

Ladies and Gentlemen:

We have acted as counsel to JPMorgan Chase Bank, N.A., as depositary (the “Depositary”), in connection with the Registration Statement on Form F-6 (the “Registration Statement”) to be filed on the date hereof with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), by the legal entity created by the Deposit Agreement (as defined below), relating to up to 50,000,000 American Depositary Shares (“ADSs”), evidenced by American Depositary Receipts (“ADRs”), each ADS representing five (5) ordinary shares, par value NT$10.00 per ordinary share, of ASLAN Pharmaceuticals Limited (the “Company”), an exempted company incorporated in the Cayman Islands. The ADSs will be issued pursuant to the Deposit Agreement (the “Deposit Agreement”), to be entered into among the Company and its successors, the Depositary and all holders from time to time of ADRs issued thereunder, a draft copy of which is being filed as Exhibit (a) to the Registration Statement. Capitalized terms used herein that are not herein defined shall have the meanings assigned to them in the Deposit Agreement.

In connection with this opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents as we considered necessary or appropriate to enable us to render this opinion, including but not limited to the Registration Statement, the Deposit Agreement and the Form of ADR included as Exhibit A to the Deposit Agreement, as well as such other corporate records, certificates and instruments as we have deemed necessary or appropriate for purposes of rendering the opinions set forth herein.

In rendering this opinion, we have assumed the genuineness and authenticity of all signatures on original documents; the legal capacity, competency and authority of all
