Limited (“MTR Cayman”) became an additional issuer of Notes under the Programme with effect from 9th April 2001 pursuant to an Amending and Restating Programme Agreement dated 9th April 2001 made between MTRCL, MTR Cayman and the Dealers named therein (MTRCL and MTR Cayman together being the “Issuers” and each an “Issuer”). This Offering Circular supersedes any previous prospectus, listing particulars or offering circular describing the Programme. Notes issued under the Programme on or after the date of this Offering Circular are subject to the provisions described herein. This does not affect any Notes issued before the date of this Offering Circular. Under the Programme, MTRCL or MTR Cayman or any other entity that may be appointed as an additional issuer under the Programme, as the case may be, (the “relevant Issuer”) may from time to time issue Notes (the “Notes”) denominated in any currency agreed upon by the relevant Issuer and the relevant Dealer(s) (as defined herein). The Notes shall have maturities that are one month or greater (subject to such minimum or maximum maturity as may be allowed or required from time to time by the relevant central bank or equivalent body (however called) or any laws or regulations applicable to the relevant currency) and, subject as set out herein, the maximum aggregate principal amount of all Notes from time to time outstanding will not exceed US$7,000,000,000 (or its equivalent in other currencies). The payment of all amounts payable in respect of Notes to be issued by MTR Cayman or any other entity that may be appointed as an additional issuer under the Programme will be unconditionally and irrevocably guaranteed by MTRCL (the “Guarantor”). The Notes will be offered through one or more of the Dealers specified under the section headed “Summary” in this Offering Circular and any additional Dealers appointed under the Programme from time to time (each a “Dealer” and together the “Dealers”) on a continuing basis whether in respect of the Programme generally or a particular issue of Notes. Application has been made to The Stock Exchange of Hong Kong Limited (the “Hong Kong Stock Exchange”) for the listing of the Programme by way of debt issues to professional investors (as defined in Chapter 37 of the Rules Governing the Listing of Securities on the Hong Kong Stock Exchange) and to professional investors (as defined in the Securities and Futures Ordinance (Cap. 571 of the Laws of Hong Kong)) (together, ‘‘Professional Investors’’) only during the 12-month period from the date of this document on the Hong Kong Stock Exchange. This document is for distribution to Professional Investors only. NoticetoHongKonginvestors:The Issuers confirm that the Notes are intended for purchase by Professional Investors only and, where they are listed on the Hong Kong Stock Exchange, are so listed on that basis. Accordingly, the Issuers confirm that the Notes are not appropriate as an investment for retail investors in Hong Kong. Investors should carefully consider the risks involved. Investors should not purchase the Notes in the primary or secondary markets unless they are Professional Investors and understand the risks involved. The Notes are only suitable for Professional Investors. The Hong Kong Stock Exchange has not reviewed the contents of this document, other than to ensure that the prescribed form disclaimer and responsibility statements, and a statement limiting distribution of this document to Professional Investors only have been reproduced in this document. Listing of the Programme and the Notes on the Hong Kong Stock Exchange is not to be taken as an indication of the commercial merits or credit quality of the Programme, the Notes or the Issuers, or MTRCL (in such capacity as the Guarantor) or quality of disclosure in this document. Hong Kong Exchanges and Clearing Limited and the Hong Kong Stock Exchange take no responsibility for the contents of this document, make no representation as to its accuracy or completeness and expressly disclaim any liability whatsoever for any loss howsoever arising from or in reliance upon the whole or any part of the contents of this document. The Notes have not been and will not be registered under the US Securities Act of 1933, as amended (the “Securities Act”) or with any securities regulatory authority of any state or other jurisdiction of the United States, and may not be offered or sold within the United States or to, or for the account or benefit of, US persons (as defined in Regulation S under the Securities Act) unless the Notes are registered under the Securities Act or an exemption from the registration requirements of the Securities Act is available. PROHIBITION OF SALES TO EEA AND UK RETAIL INVESTORS – The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”) or in the United Kingdom (“UK”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA or in the UK has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA or in the UK may be unlawful under the PRIIPs Regulation. MiFID II PRODUCT GOVERNANCE / TARGET MARKET – The pricing supplement in respect of any Notes (the “Pricing Supplement”) may include a legend entitled “MiFID II product governance” which will outline the target market assessment in respect of the Notes and which channels for distribution of the Notes are appropriate. Any person subsequently offering, selling or recommending the Notes (a “distributor”) should take into consideration the target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the target market assessment) and determining appropriate distribution channels. A determination will be made in relation to each issue about whether, for the purpose of the MiFID Product Governance rules under EU Delegated Directive 2017/593 (the “MiFID Product Governance Rules”), any Dealer subscribing for any Notes is a manufacturer in respect of such Notes, but otherwise neither the Arranger nor the Dealers nor any of their respective affiliates will be a manufacturer for the purpose of the MiFID Product Governance Rules. Notification under Section 309B(1)(c) of the Securities and Futures Act (Chapter 289) of Singapore (the “SFA”) – Unless otherwise stated in the Pricing Supplement in respect of any Notes, all Notes issued or to be issued under the Programme shall be prescribed capital markets products (as defined in the Securities and Futures (Capital Markets Products) Regulations 2018) and Excluded Investment Products (as defined in MAS Notice SFA 04-N12: Notice on the Sale of Investment Products and MAS Notice FAA-N16: Notice on Recommendations on Investment Products). Notice of the aggregate principal amount or interest (if any) payable in respect of the issue price of each Tranche (as defined herein) of Notes will be given in a Pricing Supplement which, with respect to Notes to be listed on the Hong Kong Stock Exchange, will be delivered to the Hong Kong Stock Exchange on or before the date of issue of such Notes. Copies of each Pricing Supplement will be available from the specified office of each of the Paying Agents (as defined herein). The Programme provides that Notes may be listed on such other or further stock exchanges as may be agreed between the relevant Issuer and the relevant Dealer(s), and may also be unlisted. The relevant Pricing Supplement in respect of the issue of any Notes will specify whether or not such Notes will be listed on the Hong Kong Stock Exchange or any other stock exchange.
