The distribution of this announcement in certain jurisdictions may be restricted by law. Persons into whose possession this announcement comes are required to inform themselves about and to observe any such restrictions.

This announcement does not constitute an offer or an invitation to subscribe or purchase any of the Securities. No action has been taken in any jurisdiction to permit a public offering of the Securities where such action is required other than in the US. The offer and sale of the Securities may be restricted by law in certain jurisdictions.

The Securities are complex financial instruments with a high degree of risk. They are not a suitable or appropriate investment for all investors, especially retail investors. In some jurisdictions, regulatory authorities have adopted or published laws, regulations or guidance with respect to the offer or sale of securities such as the Securities. Potential investors in the Securities should inform themselves of, and comply with, any applicable laws, regulations or regulatory guidance with respect to any resale of the Securities (or any beneficial interests therein).

a. In the United Kingdom ('UK'), the UK Financial Conduct Authority ('FCA') Conduct of Business Sourcebook ('COBS') requires, in summary, that the Securities should not be offered or sold to retail clients (as defined in COBS 3.4, and each, a 'retail client') in the UK.

b. Some or all of the underwriters are required to comply with COBS.

c. By purchasing, or making or accepting an offer to purchase, any Securities (or a beneficial interest in such Securities) from the Company and/or the underwriters, each prospective investor represents, warrants, agrees with and undertakes to the Company and each of the underwriters that:

i. it is not a retail client in the UK; and

ii. it will not sell or offer the Securities (or any beneficial interests therein) to retail clients in the UK or communicate (including the distribution of the prospectus supplement and the accompanying prospectus for the issuance of the Securities) or approve an invitation or inducement to participate in, acquire or underwrite the Securities (or any beneficial interests therein) where that invitation or inducement is addressed to or disseminated in such a way that it is likely to be received by a retail client in the UK.

d. In selling or offering Securities or making or approving communications relating to the Securities, each prospective investor may not rely on the limited exemptions set out in COBS.

e. Potential investors in the Securities should also inform themselves of, and comply with, any applicable laws, regulations or regulatory guidance with respect to any resale of the Securities (or any beneficial interests therein).

The obligations set out above are in addition to the need to comply at all times with other applicable laws, regulations and regulatory guidance (whether inside or outside the European Economic Area ('EEA') or the UK) relating to the promotion, offering, distribution and/or sale of the Securities (or any beneficial interests therein), whether or not specifically mentioned in the prospectus supplement or the accompanying prospectus for the issuance of the Securities including (without limitation) any requirements under MiFID II or the UK FCA Handbook as to determining the appropriateness and/or suitability of an investment in the Securities (or any beneficial interests therein) for investors in any relevant jurisdiction. By purchasing, or making or accepting an offer to purchase, any Securities (or a beneficial interest in such Securities) from the Company and/or the underwriters each prospective investor represents, warrants, agrees with and undertakes to the Company that it will comply at all times with all such other applicable laws, regulations and regulatory guidance.

Where acting as agent on behalf of a disclosed or undisclosed client when purchasing, or making or accepting an offer to purchase, any Securities (or any beneficial interests therein) from the Company and/or the underwriters the foregoing representations, warranties, agreements and undertakings will be given by and be binding upon both the agent and its underlying client.

PRIIPs Regulation-Prohibition of sales to EEA retail investors - The Securities 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 EEA. 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 MiFID II; or (ii) a customer within the meaning of Directive (EU) 2016/97, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the 'PRIIPs Regulation') for offering or selling the Securities or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Securities or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

UK PRIIPs Regulation-Prohibition of sales to UK retail investors - The Securities 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 UK. For these purposes, a retail investor means a person who is not a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of UK domestic law by virtue of the EUWA. Consequently, no key information document required by the Regulation (EU) No 1286/2014 as it forms part of UK domestic law by virtue of the EUWA (the 'UK PRIIPs Regulation') for offering or selling the Securities or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Securities or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.
