No fractional Shares will be issued and distributed

- 8 -

LETTER FROM THE BOARD

pursuant to the 2020 Capitalization of Reserve, but will be aggregated and sold for the benefit of the Company. Based on the current total share capital of 2,450,515,720 Shares, upon the completion of the 2020 Capitalization of Reserve, the total share capital of the Company will be approximately 2,940,618,863 Shares, provided that the actual number of Shares shall be subject to the disclosure in an announcement to be separately issued upon the completion of the statutory procedures by the Company.

The Board also proposed to make a cash dividend of RMB3.63 (inclusive of tax) for every 10 Shares (representing an aggregate amount of RMB889,537,206.36 (inclusive of tax) based on the total issued Shares of the Company as of the Latest Practicable Date). The cash dividend will also be paid on a pro-rated basis for Shareholders who hold Shares in odd lot (i.e. RMB0.363 per ordinary Share). The exchange rate to be used to convert the cash dividend from RMB to HK$ will be the average of the medium rate of RMB to HK$ announced by the People's Bank of China for five working days (the "Medium Rate") prior to and including May 13, 2021, the date on which the 2020 Profit Distribution is to be declared at the 2020 AGM and Class Meetings. For illustration purpose, the Medium Rate on the Latest Practicable Date is RMB0.84154 to HK$1. Hence, H Shareholders will receive HK$4.3135 for every 10 H Shares held by them. The 2020 Capitalization of Reserve is subject to the following conditions:

  1. approval of the Shareholders by way of special resolutions at the 2020 AGM, H Share Class Meeting and A Share Class Meeting to be held on May 13, 2021;
  2. the Hong Kong Stock Exchange granting the listing of, and permission to deal in, the 2020 Capitalization Shares;
  3. compliance with the relevant legal procedures and requirements under the Company Law of the PRC to effect the 2020 Capitalization of Reserve; and
  4. approval of the Convertible Bonds-Related Specific Mandate by the Shareholders by way of special resolution at the 2020 AGM, H Share Class Meeting and A Share Class Meeting to be held on May 13, 2021 (please refer to the section headed "6. Proposed Granting of the Convertible Bonds-Related Specific Mandate to Issue Additional Conversion Shares" below for further details on the Convertible Bonds-Related Specific Mandate,

- 9 -

LETTER FROM THE BOARD

In the event of change in the total issued share capital of the Company before the record date for determining Shareholders' entitlement to the 2020 Capitalization of Reserve and 2020 Profit Distribution, dividends will be distributed according to the original dividend amount per share and the total distribution amount and the total number of new Shares to be issued out of reserve to all Shareholders will be adjusted accordingly.

Subject to the arrangements under the Northbound Trading or Southbound Trading (defined below) as disclosed in details below, the 2020 Profit Distribution will be declared according to the Articles of Association. Dividend on A Shares will be paid in Renminbi and dividend on H Shares will be paid in Hong Kong dollars.

Status of 2020 Capitalization Shares

The 2020 Capitalization Shares will, subject to the Articles of Association, rank pari passu in all respects with the Shares in issue on the date of the issue of the 2020 Capitalization Shares. Holders of the 2020 Capitalization Shares will be entitled to receive all future dividends and distributions (if any) which are declared, made or paid after the date on which the 2020 Capitalization Shares are allotted and issued. The 2020 Capitalization of Reserve should not result in any change to the rights of the Shares. For the avoidance of doubt, the holder of the 2020 Capitalization Shares will not be entitled to the cash dividend under the proposed 2020 Profit Distribution Plan.

Overseas H Shareholders

As at the Latest Practicable Date, according to the latest register of members available to the Company, none of the H Shareholders as recorded on the register of members of the Company had an address which is outside Hong Kong.

Upon the proposed 2020 Profit Distribution Plan becoming unconditional, the Company will consider if there are any overseas H Shareholders located in other jurisdictions, and if there are such overseas H Shareholders, then the Company will make enquiry regarding the legal restrictions (if any) under the laws of the relevant places and the requirements of the relevant regulatory bodies for the relevant overseas H Shareholders to be eligible to take part in the 2020 Capitalization of Reserve and 2020 Profit Distribution pursuant to the Listing Rules.

LETTER FROM THE BOARD

  1. the acquirer of Shares agrees with the Company and its Shareholders that the Shares are freely transferable by the holder of such Shares; and
  2. the acquirer of Shares authorizes the Company to enter into a contract on his behalf with each Director and officer whereby such Directors and officers undertake to observe and comply with their obligations to Shareholders stipulated in the Articles of Association.

Warning of Risks of Dealing in the H Shares

H Shareholders should note that the existing H Shares are expected to be dealt in on an ex-entitlement basis for entitlement to the 2020 Capitalization of Reserve and the 2020 Profit Distribution from Friday, May 28, 2021. If the conditions of the 2020 Capitalization of Reserve and 2020 Profit Distribution (as set out above under the section headed "5. Proposed 2020 Profit Distribution Plan") are not fulfilled, the 2020 Capitalization of Reserve and 2020 Profit Distribution will not proceed. If in doubt, investors are recommended to consult their professional advisers.

Reasons for the 2020 Capitalization of Reserve and the 2020 Profit Distribution

Based on the positive expectations on the future development of the Company, and with reference to the operating results and the overall financial status of the Company, the Board proposed the 2020 Capitalization of Reserve and the 2020 Profit Distribution so as to share the fruitful result of the Company's business performance with the Shareholders.

In addition, to encourage the Shareholders to continue to support the Company's future development, the Board believes that the 2020 Capitalization of Reserve will allow the Shareholders to enjoy a pro-rata increase in the number of Shares held by them in the Company without incurring any significant costs to them. Although the 2020 Capitalization of Reserve is not expected to increase the Shareholders' proportionate equity interests in the Company, the 2020 Capitalization of Reserve will increase the number of Shares to be held by the Shareholders, which will afford the Shareholders with more flexibility in managing their own investment portfolios such as giving them more convenience in disposing of a portion of the Shares for cash return. The 2020 Capitalization of Reserve will also result in the increase of number of Shares in issue, and the number of Shares held by H Shareholders, which will motivate the trading of Shares by the H Shareholders, and thus will enhance the trading activities and liquidity of the Shares in the market.

7. PROPOSED ADJUSTMENT TO THE ANNUAL ALLOWANCE OF INDEPENDENT NON-EXECUTIVE DIRECTORS

An ordinary resolution will be proposed at the 2020 AGM to consider and approve the adjustment to the annual allowance of the independent non-executive Directors.

As the independent non-executive Directors have proactively, diligently and responsibly performed their duties during their past tenures of service, provided constructive guiding opinion for the standardized operations and strategic development of the Company, and made significant contribution, having taken into account the level of allowance in the industry, regional economic development, together with the actual operational circumstances of the Company, the profits of the Company and the workload and professionalism of the independent non-executive Directors, the Board proposed to, upon the recommendation of the Remuneration and Appraisal Committee of the Company, adjust the annual allowance of independent non-executive Directors.

At present, the annual allowance for independent non-executive Directors is RMB300,000 (before tax). An ordinary resolution will be proposed at the 2020 AGM to consider and approve the increase of the annual allowance of the independent non-executive Directors to RMB400,000 (before tax). If such independent non-executive Director worked less than one year, his or her remuneration shall be calculated on a pro-rata and daily basis.

Overview of the proposed related parties transactions

The Application for Shares

It is proposed that STA Pharmaceutical, a wholly-owned subsidiary of STA and an indirect non-wholly-owned subsidiary of the Company, will, together with WuXi Bio, make capital contributions (the "Capital Contribution") to WuXi XDC (Cayman) Inc. ("WuXi XDC"). WuXi XDC shall first repurchase 1 ordinary share in its share capital held by WuXi Bio at a consideration of US$1.00. Concurrently, STA Pharmaceutical will enter into an application for shares with WuXi XDC to subscribe for and WuXi XDC will issue 2 ordinary shares, which represents 40% of the issued share capital of WuXi XDC at a consideration of US$80,000,000 (the "Application for Shares"), while WuXi Bio will enter into an application for shares with WuXi XDC to subscribe for and WuXi XDC will issue 3 ordinary shares, which represents 60% of the issued share capital of WuXi XDC at a consideration of US$120,000,000. The capital contribution ratio and the consideration of the capital contribution have been determined after arm's length negotiations between STA Pharmaceutical and WuXi Bio with reference to, among other things, (i) the consideration of the ADC Acquisition (as defined below) and the acquisition of the Target Assets (as defined below) pursuant to the Asset Transfer Agreement (as defined below); (ii) the capital expenditure required to expand the ADC R&D capability and GMP manufacturing capability and scale of WuXi XDC; and (iii) the daily operational capital required by WuXi XDC. The consideration to be paid by STA Pharmaceutical will be funded by the Group's internal financial resources.

LETTER FROM THE BOARD

As disclosed in the 2020 interim report of the Company, subsequent to the completion of the placing of 60,000,000 existing shares of WuXi Bio held by WuXi Biologics Holdings Limited on May 25, 2020, (i) the shareholding held by WuXi Biologics Holdings Limited in WuXi Bio decreased from approximately 31.49% to 26.89% of the total issued share capital of the WuXi Bio; and (ii) WuXi Biologics Holdings Limited ceased to be a controlling shareholder of WuXi Bio. Since Dr. Ge Li, together with the other Founding Individuals who are also Directors, control 58.42% of the voting power of WuXi Biologics Holdings Limited, they are deemed to be interested in the shares of WuXi Bio held by WuXi Biologics Holdings Limited. As a result, WuXi Bio is no longer a 30%-controlled company (as defined under the Listing Rules) of Dr. Ge Li and the other Founding Individuals. Accordingly, WuXi Bio is no longer an associate of Dr. Ge Li and the other Founding Individuals and hence no longer a connected person of the Company under Chapter 14A of the Listing Rules.

WuXi XDC is a company incorporated in the Cayman Islands. WuXi XDC is principally engaged in investment holding, while its subsidiaries are principally engaged in the R&D, manufacturing and commercialization of ADC, payload and linker. As at the Latest Practicable Date, it is a wholly-owned subsidiary of WuXi Bio.

Starting with contracted research and development and manufacturing of ADC, we will establish an "end-to-end" Contract Development and Manufacturing Organization (CDMO) company specializing in drug conjugate. WuXi XDC will provide "one-stop" services to better satisfy the growing demand of global customers for research and development and manufacturing services related to such new drug molecules and also simplify the CMC process and supply chain management of ADC from development to commercialization

LETTER FROM THE BOARD

and thus, shorten the drug launching process of our business partners so as to help patients earlier. As the parent company of a shareholder holding 40% equity interests in WuXi XDC, and through WuXi Conjugation adhering to the Company's strategy of expanding services "along with the development of drugs", it is expected that clients who originally cooperate with only STA or WuXi Bio can be developed into clients that utilize the "end-to-end" services provided by WuXi XDC, thereby increasing the average revenue generated from each client, which would in turn enable the Company to obtain investment gains through WuXi XDC.. The Company may also receive income from providing WuXi XDC with research and development and manufacturing services of small molecule chemical drugs, polypeptide drugs and oligonucleotide drugs.

The terms of the Capital Contribution and the Application for Shares, the Amended and Restated WuXi XDC Articles, the ADC Acquisition, the Asset Transfer Agreement and the transactions contemplated thereunder, as well as the expected annual caps of the Potential Continuing Related Parties Transactions, were agreed after arm's length negotiations among the parties thereto. The Directors (including the independent non-executive Directors) are of the view that the terms of the Capital Contribution and the Application for Shares, the Amended and Restated WuXi XDC Articles, the ADC Acquisition, the Asset Transfer Agreement and the transactions contemplated thereunder, as well as the expected annual caps of the Potential Related Parties Transactions, are fair and reasonable and are in the interests of the Company and the Shareholders as a whole.

Implications under the Shanghai Listing Rules

Since Dr. Ge Li, Mr. Edward Hu and Dr. Yibing Wu, who are Directors, also serve as the directors of WuXi Bio, and WuXi Bio was controlled by the Founding Individuals within a 12-month period, WuXi Bio is a related party of the Company under the Shanghai Listing Rules. Given WuXi XDC, WuXi Conjugation and the Changzhou Subsidiary (to be set up) are controlled corporations of WuXi Bio, WuXi XDC, WuXi Conjugation and the Changzhou Subsidiary are also related parties of the Company under the Shanghai Listing Rules. As such, the Application for Shares, the Amended and Restated WuXi XDC Articles, the Asset Transfer Agreement and the transactions contemplated thereunder, as well as the Potential Continuing Related Parties Transactions are related party transactions of the Company under the Shanghai Listing Rules. Pursuant to the Shanghai Listing Rules, transaction amounts under all types of related party transactions entered into in the ordinary and usual course of business of the Company and entered into between the Company and the same related party within a 12-month period should be aggregated (save for those which have complied with the relevant approval and/or disclosure procedures), and the transaction amounts under the same type of related party transactions entered into between the Company and different related parties within a 12-month period should be aggregated (save for those which have complied with the relevant approval and/or disclosure procedures), and if the total aggregated transaction amount exceeds 5% of the audited net asset

- 28 -

LETTER FROM THE BOARD

attributable to the owners of the Company as at the end of the most recent financial year, such related party transactions should be presented to a general meeting for independent shareholders' approval. As the aggregate transaction amount of the Application for Shares, the Amended and Restated WuXi XDC Articles, the Asset Transfer Agreement and the transactions contemplated thereunder, as well as the Potential Continuing Related Parties Transactions exceeds 5% of the audited net asset attributable to the owners of the Company as at the end of the most recent financial year, and the aggregate transaction amount of the Application for Shares and the Amended and Restated WuXi XDC Articles as well as the transactions contemplated thereunder, together with joint investment transactions entered into with different related parties within a 12-month period, exceed 5% of the audited net asset attribution to the owners of the Company as at the end of the most recent financial year, the Application for Shares, the Amended and Restated WuXi XDC Articles, the Asset Transfer Agreement and the transactions contemplated thereunder, as well as the Potential Continuing Related Parties Transactions, are subject to Shareholders' approval requirement under the Shanghai Listing Rules.

Implications under the Hong Kong Listing Rules

As (i) WuXi Bio, WuXi XDC and WuXi Conjugation are not connected persons of the Company under the Hong Kong Listing Rules and the applicable percentage ratios in respect of the Application for Shares and the transactions contemplated thereunder, as well as the expected annual caps of the Potential Continuing Related Parties Transactions are less than 5%; and (ii) the ADC Acquisition and the Asset Transfer Agreement are to be entered into through WuXi XDC which is not a subsidiary of the Company and a part of the Group since WuXi XDC will only be held as to 40% by the Company, and STA Pharmaceutical can only nominate two out of five directors to the board of WuXi XDC; and (iii) the applicable percentage ratios in respect of the Asset Transfer Agreement are less than 5%, the Application for Shares, the Amended and Restated WuXi XDC Articles, the ADC Acquisition, the Asset Transfer Agreement and the transactions contemplated thereunder, as well as the Potential Continuing Related Parties Transactions, do not constitute connected transactions or discloseable transactions of the Company under Chapter 14A and Chapter 14 of the Hong Kong Listing rules, respectively.

Nevertheless, given such related party transactions are subject to independent Shareholders' approval pursuant to the Shanghai Listing Rules as abovementioned, an ordinary resolution will be proposed at the 2020 AGM for the Shareholders to consider and, if thought fit, approve the Application for Shares, the Amended and Restated WuXi XDC Articles, the Asset Transfer Agreement and the transactions contemplated thereunder, as well as the Potential Continuing Related Parties Transactions.

- 29 -

LETTER FROM THE BOARD

  1. Dr. Ge Li, Mr. Edward Hu and Dr. Yibing Wu, being Directors and also the directors of WuXi Bio; (ii) Dr. Steve Qing Yang, being a Director and also a director of WuXi XDC; and (iii) Dr. Ning Zhao and Mr. Zhaohui Zhang, being Directors who exercised control over WuXi Bio within the period of the past 12 months, have abstained from voting on the relevant Board resolutions approving the Application for Shares, the Amended and Restated WuXi XDC Articles, the Asset Transfer Agreement and the transactions contemplated thereunder, as well as the Potential Continuing Related Parties Transactions. Save as aforementioned, none of the other Directors has a material interest in the Application for Shares, the Amended and Restated WuXi XDC Articles, the Asset Transfer Agreement and the transactions contemplated thereunder, as well as the Potential Continuing Related Parties Transactions. Therefore, no other Director has abstained from voting on such Board resolutions.

General

WuXi XDC is still subject to construction and refinement in aspects such as manpower allocation and operational management. Whether WuXi XDC can successfully attain all its expected targets is therefore uncertain. In addition, the future business development of WuXi XDC is subject to the impact of factors such as industry policies, market environment and operational management. As such, the expected revenue of WuXi XDC is uncertain.

9. PROPOSED PROVISION OF EXTERNAL GUARANTEES FOR SUBSIDIARIES

APPENDIX VII EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

The following is an explanatory statement required by the Hong Kong Listing Rules to provide the Shareholders with requisite information reasonably necessary for them to make an informed decision on whether to vote for or against the special resolutions to be proposed at the 2020 AGM, the H Share Class Meeting and the A Share Class Meeting in relation to the granting of the Repurchase Mandate.

1. SHARE CAPITAL

As at the Latest Practicable Date, the issued share capital of the Company comprised 2,134,858,437 A Shares and 315,657,283 H Shares. Subject to the passing of the special resolutions set out in the 2020 AGM, the H Share Class Meeting and the A Share Class Meeting in respect of the granting of the Repurchase Mandate and on the basis that the issued share capital of the Company remains unchanged on the date of the 2020 AGM, i.e. being 2,134,858,437 A Shares and 315,657,283 H Shares, the Directors would be authorized under the Repurchase Mandate to repurchase, during the Relevant Period (as defined below), a total of 213,485,843 A Shares and 31,565,728 H Shares, representing 10% of the total number of A Shares and H Shares in issue as at the date of the 2020 AGM, respectively. The exercise of the Repurchase Mandate is further subject to:

  1. the obtainment of an approval from all relevant regulatory authorities having jurisdiction over the Company (if applicable) as required by the laws, regulations and rules of the PRC; and
  2. the Company not being required by any of its creditors to repay or to provide guarantees in respect of any amount due to any of them (or if the Company is so required by any of its creditors, the Company having, at its absolute discretion, repaid or provided guarantee in respect of such amount) pursuant to the notification procedures under the "Company Law of the People's Republic of China" and the Articles of Association of the Company. If the Company determines to repay any amount to any of its creditors, the Company will do so out of its internal funds.

The "Relevant Period" means the period from the passing of the resolution at the 2020 AGM and the passing of those resolutions having the same terms with this resolution at its A Share Class Meeting and H Share Class Meeting, respectively, until whichever is the earliest of:

  1. upon conclusion of the 2021 annual general meeting of the Company;
  2. the expiration of a period of twelve months following the passing of this resolution at the 2020 AGM and the passing of those resolutions having the same terms with this resolution at its A Share Class Meeting and H Share Class Meeting, respectively; or

- VII-1 -

APPENDIX VII EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

  1. the time at which the authorization conferred by this resolution is revoked or varied by a special resolution of the Shareholders at a general meeting, or by a special resolution of its H shareholders and A shareholders at the H Share Class Meeting and the A Share Class Meeting, respectively.

2. REASONS FOR SHARE REPURCHASE

The Directors believe that a general authority from the Shareholders to enable the Company

to repurchase its Shares is to maintain stability of the Company's operations, development and share price, to safeguard and protect the long-term interests of the Shareholders, to promote the maximization of Shareholders' value, to further improve and refine the long-term incentive and talent retention mechanism, and to ensure the sustainable operations and healthy development of the Company.

3. FUNDING OF SHARE REPURCHASE

In repurchasing its A Shares and/or H Shares, the Company intends to apply funds from its internal resources (which may include surplus funds and retained profits) legally available for such purpose in accordance with its Articles of Association, the laws of the PRC and/or any other applicable laws, as the case may be.

4. IMPACT OF SHARE REPURCHASE

Any repurchase of the Shares by the Company may only be made either out of the funds of the Company that would otherwise be available for dividend or distribution or out of the proceeds of the issuance of new Shares made for such purpose. The amount of financing required for the Company to purchase or acquire its Shares, and the impact on the Company's financial position, cannot be ascertained as at the Latest Practicable Date as these will depend on whether the Shares are purchased or acquired out of capital or profits, the number of shares purchased or acquired and the price at which such Shares were purchased or acquired. There might be a material adverse impact on the working capital or gearing position of the Company (as compared with the position disclosed in the audited consolidated financial statements contained in the annual report of the Company for the year ended December 31, 2019) in the event that the Repurchase Mandate was to be carried out in full at any time during the proposed repurchase period. However, the Directors do not intend to exercise the Repurchase Mandate to such extent as would, in the circumstances, have a material adverse effect on the working capital requirements of the Company or the gearing levels which in the opinion of the Directors are from time to time appropriate for the Company.

6. GENERAL

To the best of their knowledge and having made all reasonable enquiries, none of the Directors nor any of their respective close associates (as defined in the Hong Kong Listing Rules) have any present intention to sell any Shares to the Company in the event that the granting of the Repurchase Mandate is approved by the Shareholders.

The Company has not been notified by any core connected persons (as defined in the Hong Kong Listing Rules) of the Company that they have a present intention to sell any Shares to the Company, or that they have undertaken not to sell any Shares held by them to the Company in the event that the granting of the Repurchase Mandate is approved by the Shareholders.

- VII-3 -

APPENDIX VII EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

The Directors have undertaken to the Hong Kong Stock Exchange to exercise the power of the Company to repurchase A Shares and/or H Shares pursuant to the Repurchase Mandate in accordance with the Hong Kong Listing Rules and the applicable laws of the PRC.

7. TAKEOVERS CODE

If as a result of a repurchase of A Shares and/or H Shares pursuant to the Repurchase Mandate, a Shareholder's proportionate interest in the voting rights of the Company increases, such increase will be treated as an acquisition of voting rights for the purposes of the Takeovers Code. Accordingly, a Shareholder or a group of Shareholders acting in concert (within the meaning under the Takeovers Code), depending on the level of increase in the Shareholder's interest, could obtain or consolidate control of the Company and thereby become obliged to make a mandatory offer in accordance with Rule 26 of the Takeovers Code.

To the best knowledge of the Company, as at the Latest Practicable Date, the Founding Individuals held or controlled the voting rights of 633,938,346 Shares representing approximately 25.87% of the total issued share capital of the Company. In the event that the Directors exercise the proposed Repurchase Mandate in full, the aggregate control over voting rights of the Founding Individuals would be increased to approximately 28.74% of the issued share capital of the Company. The Directors consider that such increase in shareholding would not give rise to an obligation to make a mandatory offer under Rule 26 of the Takeovers Code.

Under the Administration of the Takeover of Listed Companies Procedures ( 上市公司收購 管理辦法》) in the PRC, where the repurchase of shares from specific shareholders by a listed company according to the determined price approved by the general meeting of shareholders results in reduction of share capital, thereby rendering the equity held by the investor in the company exceeding 30% of the issued shares of that company, the investor is exempted from making a tender offer. In the event of any intention to increase the shareholding by means other than tender offer, a general tender offer shall be sent out. Therefore, where the Repurchase Mandate is exercised in full and the aggregate control over voting rights of the Founding Individuals would be increased to approximately 28.74%, the Founding Individuals will have no obligation to extend general tender offer to other shareholders.

Save as the above, the Directors are not aware of any consequences which will arise under either or both of the Takeovers Code and any similar applicable law as a result of any repurchases to be made under the Repurchase Mandate.

- VII-4 -

APPENDIX VII EXPLANATORY STATEMENT ON THE REPURCHASE MANDATE

However, the Directors do not propose to exercise the Repurchase Mandate to such an extent as would, in the circumstances, give rise to an obligation to make a mandatory offer in accordance with Rule 26 of the Takeovers Code and/or result in the aggregate number of Shares held by the public shareholders falling below the prescribed minimum percentage required by the Hong Kong Stock Exchange.

8. SHARE REPURCHASE MADE BY THE COMPANY

On December 17, 2020, the repurchase and cancellation of an aggregate of 336,008 Restricted A Shares granted under the 2018 A Share Incentive Plan and the 2019 A Share Incentive Plan, which comprise (i) 69,778 Restricted A Shares granted under the initial grant of the 2018 A Share Incentive Plan at the repurchase price of RMB22.75 per A Share; and (ii) 266,230 Restricted A Shares granted under the initial grant of the 2019 A Share Incentive Plan at the repurchase price of RMB22.95 per A Share, pursuant to the relevant provisions of the 2018 A Share Incentive Plan and the 2019 A Share Incentive Plan, was completed. Please refer to the relevant announcements of the Company dated October 19, 2020, December 14, 2020 and December 17, 2020 for further details.

Save as disclosed above, during the six months prior to the Latest Practicable Date, the Company had not repurchased any of the Shares (whether on the Hong Kong Stock Exchange, Shanghai Stock Exchange or otherwise).

- VII-5 -

APPENDIX VIII

PROPOSED FOREIGN EXCHANGE HEDGING LIMIT

In accordance with its current business development and future development strategy, the international business volume of the Company will continue to increase with higher foreign exchange exposure. When the exchange rate fluctuates significantly, the gains and losses on foreign exchanges will have certain impact on the Company's operating performance. In order to effectively prevent the adverse impact of significant exchange rate fluctuations on its operations and reduce foreign exchange risk, the Company has carried out a foreign exchange hedging business with banks since 2017. With the global economic recovery, the divergence of monetary policy among countries has gradually emerged, the RMB exchange rate system has undergone in-depth reform, with increased fluctuations in the RMB exchange rate. Under this background, the Company believes that it is necessary to continue to carry out the forward foreign exchange settlement and sales business with banks in 2021 to lock the exchange rate, and reduce the impact of exchange rate fluctuations on its operating profit, in active response to the uncertainties in the exchange rate market.

Taking into consideration its export income level, the management of the Company proposes that the total amounts of the foreign exchange hedging business carried out by the subsidiaries within the scope of the Company and its consolidated statements in 2021 (hereinafter referred to as the "subsidiaries") shall not exceed US$3 billion or other equivalent foreign currencies. The proposed foreign exchange hedging businesses includes, but not limited to, futures business, swap business, exchange swaps, option business and other foreign exchange derivative products, and the major currencies are United States dollars and Hong Kong dollars. The term shall be from the date of the approval of this resolution at the 2020 AGM to the date of the general meeting of 2021.

In order to standardize the foreign exchange derivatives trading business of the Company and its subsidiaries and ensure the safety of the Company's assets, the management proposes that the Board of Director, under authorization of the general meeting of the Company, further authorizes its financial department to carry out the foreign exchange derivatives trading business within the quota approved at the general meeting based on the business conditions and actual demand on the premise of being approved at the general meeting of the Company. All the foreign exchange derivatives trading businesses of all subsidiaries shall be reported to the Company's financial department for approval, and then further complete its own internal procedures before the relevant businesses can be implemented.
