The distribution of this release and the related material concerning the issuance of the New Notes may, in certain jurisdictions, be restricted by law. No actions have been taken to register or qualify the New Notes, or otherwise to permit a public offering of the New Notes, in any jurisdiction. If Y-Säätiö decides to proceed with the issue of the New Notes, any offering material or documentation related to the New Notes may be received only in compliance with applicable exemptions or restrictions. Persons into whose possession this release or any such offering material or documentation may come are required to inform themselves of and observe all such restrictions. This release and any such offering material or documentation may not be distributed or published in any country or jurisdiction if to do so would constitute a violation of the relevant laws of such jurisdiction or would require actions under the laws of a state or jurisdiction other than Finland. In particular, this release and any such offering material or documentation may not be distributed in the United States, Australia, Canada, Hong Kong, Japan, New Zealand, Singapore or South Africa or any other jurisdiction in which it would not be permissible to offer the New Notes and this release and any related material concerning the issuance of the New Notes may not be sent to any person in the before mentioned jurisdictions. The information contained herein shall not constitute an offer to sell or tender, or a solicitation of an offer to buy or sell any of Y-Säätiö’s securities, including the New Notes, to any person in any jurisdiction in which such offer, solicitation or sale or tender would be unlawful. None of Y-Säätiö, the Dealer Manager, the Tender Agent nor the Joint Lead Managers or their representatives accept any legal responsibility for any violation by any person, whether or not the persons contemplating investing in or divesting Y-Säätiö’s securities, including the New Notes, are aware of such restrictions. This communication does not constitute an offer of securities for sale in the United States. The New Notes have not been and will not be registered under the Securities Act or under the applicable securities laws of any state of the United States and may not be offered, sold, pledged or otherwise transferred, directly or indirectly, within the United States or to, or for the account or benefit of, any U.S. persons except pursuant to an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. Y-Säätiö has not authorised the offering of the New Notes to the public in any member state of the European Economic Area (the “EEA”) or in the United Kingdom (each a “relevant state”). All offers of the New Notes in that relevant state will be made pursuant to an exemption under Regulation 2017/1129 of the European Parliament and of the Council (as amended, the “Prospectus Regulation”) (as the Prospectus Regulation forms part of domestic law of the United Kingdom by virtue of the European Union (Withdrawal) Act 2018) from the requirement to produce a prospectus under the Prospectus Regulation for offers of securities. Accordingly, any person making or intending to make any offer of the New Notes within that relevant state should only do so in circumstances in which no obligation arises for Y-Säätiö or the Joint Lead Managers to publish a prospectus under the Prospectus Regulation for such offer. Neither Y-Säätiö nor the Joint Lead Managers have authorised, nor do they authorise, the making of any offer of securities through any financial intermediary. In relation to each relevant state an offer to the public of any New Notes may not be made in a relevant state, except that an offer of the New Notes to the public in a relevant state may be made as part of the Offering pursuant to the following exemptions from the Prospectus Regulation: (i) an offer is addressed solely to qualified investors as defined in the Prospectus Regulation, (ii) an offer is addressed to fewer than 150 natural or legal persons per relevant state (other than qualified investors as defined in the Prospectus Regulation) or (iii) in any other circumstances falling within Article 1(4) of the Prospectus Regulation, provided that no such offer of New Notes shall require Y-Säätiö or any Joint Lead Managers to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation. For the purposes of this provision, the expression an “offer to the public” in relation to any of the New Notes in any relevant state means the communication in any form and by any means of sufficient information on the terms of the offer and any New Notes to be offered so as to enable an investor to decide to purchase any New Notes.
