Publity is the operator of the Platform, which is available at www.preos-token.de. The Platform serves the handling of the public offer of PREOS Tokens, the subscription for PREOS Tokens, the presentation of information and the brokerage of PREOS tokens via the OTC Trading Platform (expected to be available from January 2021) with Bankhaus Scheich as investment broker (Anlagevermittler). 2.2. Publity is the issuer of the PREOS Tokens and offers the PREOS Tokens for subscription via the Platform as part of the Issue. Publity also reserves the right to specifically name further subscription channels. 2.3. In the course of the Issue, Publity presents the PREOS Tokens to the users and provides information about them. 2.4. Bankhaus Scheich will act as investment broker (Anlagevermittler) on the OTC Trading Platform, where users can place buy and sell offers for PREOS Tokens on an over-the-counter basis. Bankhaus Scheich is not permitted to obtain ownership or possession of the funds or the PREOS Tokens of the users while performing brokerage services. 2.5. The brokerage services of Bankhaus Scheich are subject to regulatory requirements, in particular to a legal obligation to record and retain records in accordance with § 83 of the German Securities Trading Act (WpHG). 2.6. In principle, Publity assumes the user administration for investments in PREOS Tokens, unless other- wise specified and announced in individual cases. 2.7. Publity and Bankhaus Scheich expressly do not provide any asset, investment or tax advice. The in- formation made available on the Platform or in any other way does not constitute the provision of personal recommendations to the user, which relate to transactions with PREOS Tokens and are not based on an examination of the personal circumstances of the user or are not presented as suitable for the user. Rather, it is legally non-binding information or risk warnings that Publity and Bankhaus Scheich are legally obliged to provide. Users are advised to seek advice from appropriately qualified experts before subscribing to a capital investment in PREOS Tokens. § 3 PREOS Tokens; legal status of holders of PREOS Tokens; custody 3.1. The PREOS Tokens are investment bearer tokens, which represent essential shareholder rights medi- ated by a trustee as well as a right to exchange PREOS Tokens at any time for existing PREOS Shares from the previous holdings of Publity with the same profit participation entitlement as all other existing PREOS Shares and a proportionate amount of the share capital of PREOS Real Estate of EUR 1.00 per underlying PREOS Share. One (1) PREOS Token represents shareholder rights and a right to exchange in relation to one (1) PREOS Share; the ratio is therefore 1:1. 3.2. The PREOS Tokens are issued and managed on the Ethereum blockchain. 3.3. The PREOS Tokens will be transferred by Publity to the subscribers in the course of the Issue, by transferring the trustor position represented by the PREOS Tokens including all rights and obligations foreseen in the underlying Trust and Token Terms and Conditions (the "Trust and Token Terms and Conditions"; the rights and obligations from the Trust and Token Terms and Conditions as a whole also the "Trust Relationship", the Trust Relationship with regard to a single trust share also the "Partial Trust Relationship") with regard to the PREOS Shares to the subscribers by means of transfer of contract. As a result, Publity will withdraw from the underlying Trust Relationship in the course of the Issue. 3.4. The holders of PREOS Tokens (the "Token Holders") assume the position of trustors with regard to the PREOS Shares by transfer of contract. Following the Issue, the claims of the Token Holders with regard to the PREOS Tokens are (exclusively) directed against the trustee appointed by Publity, the PREOS Blockchain (the "Trustee"), which as trustee exercises certain shareholder rights for the ac- count and on the instructions of the Token Holders and is obliged to exchange the PREOS Tokens for PREOS Shares at the request of the Token Holders.
