§ 2 Business object

2.1. 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.

3.5. Only the Trustee is the legal owner of the PREOS Shares in relation to third parties and thus share- holder of PREOS Real Estate. In the relationship between Token Holder and Trustee, it is agreed on the basis of the Trust Relationship that the Trustee holds the PREOS Shares on behalf and for the account of, and in accordance with the instructions of, the respective Token Holder (trustor). In addi- tion, the Token Holder is entitled to exchange the PREOS Tokens for PREOS Shares at any time and have those PREOS Shares transferred to a securities account, specified in the course of the registration on the Platform, in accordance with the Trust Relationship. The exact scope of the Token Holder's property, administration and exchange rights in the form of rights to issue instructions to the Trustee is determined by the Trust and Token Terms and Conditions, which are made available to the user in the course of the subscription for PREOS Tokens.

3.6. The transfer of the tokenised trust position and thus of the beneficial ownership of the trust shares held in custody is only possible to third parties, who

a. have registered themselves on the Platform,

b. have undergone the required anti-money laundering checks, and

c. have provided the information required for the exercise of the rights under the respective Partial Trust Relationship (in particular, the information required for making payments and transferring the trust shares).

3.7. The trust relationship and thus the beneficial ownership of the trust shares held in custody can be transferred to third parties without the consent of the Trustee or a trustor not involved in the relevant Partial Trust Relationship. The transfer is executed by way of an agreement between the trustor and the acquirer of the tokenised Trust Relationship, through which the acquirer assumes the position of the trustor under the respective Partial Trust Relationship. All declarations required for the transfer of the tokenised trust position and the transfer of the contract are deemed to have been made and accepted without reservation by the Trustee, the trustor and the acquirer of the tokenised trust posi- tion through the transfer of the relevant PREOS Tokens. A transfer of individual claims or rights en- shrined in a Partial Trust Relationship is not permitted.

3.8. The effectiveness of the transfer of the tokenised trust position and thus the beneficial ownership of the trust shares held in custody is subject to the condition precedent that a confirmed technical trans- fer of the relevant PREOS Token from the selling trustor to the acquiring trustor occurs on the Ethereum Mainnet network. A transfer is confirmed in this sense if the status of such a transaction is indicated on www.etherscan.io with "success".

3.9. Unless stipulated otherwise, the tokenised trust position and thus the beneficial ownership of the trust shares held in custody may only be transferred by way of singular succession (Einzelrechtsnachfolge) together with the corresponding PREOS Token.

3.10. In the relation to the Trustee and every other Token Holder and trustor, a Token Holder is deemed to be the trustor with regard to the trust share represented by the respective PREOS Token under the Trust Relationship. The Token Holder is always the person who can be identified by the Platform operator via the corresponding Ethereum address and the associated private access key.

3.11. In exceptional cases, the material entitlement (materielle Berechtigung) regarding the tokenised trust position and thus the beneficial ownership of the trust shares held in custody may also be proven to the Trustee in another suitable manner. This applies, in particular, (i) if the materially entitled person no longer has access to the PREOS Tokens or (ii) in all cases in which the trust position is transferred as part of a universal succession (Gesamtrechtsnachfolge). In these cases, suitable proof of the ma- terial entitlement must be provided (e.g. in the case of inheritance, by presenting a certificate of inheritance). Should such proof be provided to the satisfaction of the Trustee, the corresponding trust shares shall be transferred by the Trustee to a securities account to be designated by the entitled person.

3.12. The token standard used is an ERC-20 compatible standard as part of the standard for security tokens, ERC 1400, on the Ethereum blockchain. A PREOS Token is issued for each security sui generis (in the form of the Trust and Token Terms and Conditions) to be issued. Neither a global certificate (Glob- alurkunde) nor individual certificates (Einzelurkunden) or interest coupons are issued for the underly- ing trust agreements. In the absence of a conventional securitization, no certificate is deposited with a custodian bank in relation to the PREOS Tokens.

3.13. Ownership of the PREOS Tokens results exclusively from the publicly visible register of the correspond- ing smart contract on the Ethereum blockchain. Only the Token Holders documented in this way are entitled to assert the rights arising from the Trust Relationship in relation to the PREOS Shares (in- cluding the exchange claim) against the Trustee.

3.14. The smart contract of the PREOS Token is assigned a register on the Ethereum blockchain, from which all token transfers and a list of addresses holding the respective PREOS Token can be seen. The Token Holders are not entered in the register by their names, but with their respective Ethereum addresses, which can be viewed in the block explorer (https://etherscan.io). From this point on, a user can dispose of the PREOS Tokens. The respective transaction can be traced by anyone on the Ethereum blockchain and the PREOS Tokens can be unambiguously assigned to a user or his Ethereum address, respec- tively. A function in the smart contract ensures that the maximum number of PREOS Tokens to be generated is technically limited.

3.15. The IT application required by the users to interact with the Ethereum blockchain ("Wallet") which also facilitates the management of the private key to an Ethereum address to which the PREOS Tokens are transferred, i.e. digitally assigned for further use, must be technically compatible with the Ethereum blockchain.

3.16. In the course of the Issue of PREOS Tokens following the registration on the Platform, users are assigned a Wallet offered by Upvest free of charge with the corresponding Ethereum address on the Ethereum blockchain to which the PREOS Tokens assigned to the respective user are transferred in the course of the Issue.

3.17. Following the transfer of the PREOS Tokens to the Ethereum address assigned to the user in the course of the Issue, the PREOS Tokens may be transferred to other Ethereum addresses and users may use other custody solutions ("Self-Custody"), provided that the address or Wallet data can at any time be attributed to the user who has been checked and accepted in terms of anti-money laun- dering law (so-called 'whitelisting'). The user is obliged to store only such address or Wallet data for any Self-Custody solution on the Platform that can be attributed to the user in such sense. In the event of infringement, he may be excluded from the Platform; the right to claim damages is reserved. In this respect, the decision as to the correct Wallet and address (compatible with the Ethereum blockchain) lies solely with the user.

3.18. If the PREOS Tokens are transferred to an incompatible Wallet, the user generally no longer has the opportunity to access and dispose of the PREOS Tokens. For the user, this would mean a total loss of his investment.

3.19. Unless the user uses the Wallet offered by Upvest via the Platform, the user bears sole responsibility for the secure storage of the private access key (private keys) for his Ethereum address in order to receive and dispose of PREOS Tokens. The loss or theft of the private keys is equivalent to the loss of all PREOS Tokens assigned to the Ethereum address. The user must apply appropriate security stand- ards when accessing the Wallet offered by Upvest and is therefore responsible for secure access to the Wallet offered by Upvest.

3.20. Further details on the legitimation effect (Legitimationswirkung) of the PREOS Tokens, the legal status of the Token Holders, the transfer of the PREOS Tokens and the Trust Relationship are governed by the Trust and Token Terms and Conditions, which are made available to the user in the course of the subscription to PREOS Tokens.

§ 4 Platform

I. Technical requirements and communication

4.1. The Platform can only be accessed via a web browser running on a computer or mobile device with an internet connection. Other access methods are not supported.

4.2. With the creation of an account on the Platform, all communication between Publity and the user in connection with the subscription, the OTC Trading Platform and the Wallet is conducted exclusively in electronic form via an inbox or by email, unless otherwise expressly stated in these GTC or required by law. Declarations will not be sent to the user additionally in paper form, unless there is a legal obligation to do so. The user agrees with this way of communication.

II. Content and registration; obligation of users to cooperate and exercise due diligence

4.3. The Platform enables its visitors to obtain information about PREOS Tokens and to subscribe for these PREOS Tokens as registered users in compliance with the law and the conditions of the respective offer or private placement in the course of the Issue and to trade on the OTC Trading Platform. Bankhaus Scheich will act as investment broker (Anlagevermittler) on the OTC Trading Platform.

4.4. In order to subscribe for and trade PREOS Tokens via the Platform, visitors of the Platform must register themselves as users and truthfully provide the requested personal data during such registra- tion. In doing so, they must undergo an identification process in accordance with anti-money launder- ing law led by Bankhaus Scheich, including a video identification, and – in the case of natural persons as users – an appropriateness test in accordance with securities trading law, as well as being approved by Bankhaus Scheich as a user verified under anti-money laundering law. Publity and Bankhaus Scheich may demand proof in this respect and reserve the right to demand further details and proof in individual cases. The visitor or user, respectively, is obliged to provide the required proof and to participate in an authentication procedure. If the visitor or user, respectively, does not fulfill the obli- gation to cooperate, the visitor or user, respectively, cannot be granted access to the Platform or – in case of violation of ongoing cooperation obligations during the contractual relationship – may be ex- cluded from the Platform.

4.5. Publity and Bankhaus Scheich reserve the right to refuse the registration of visitors and the use of the Platform by users on the basis of their (residential) seat or origin for reasons of anti-money laundering law. The same applies with regard to companies as users and their beneficial owners.

4.6. Natural persons as users are only permitted to register if they:

a. have reached at least 18 years of age,

b. have unlimited legal capacity,

c. act on the Platform in their own name and on their own account, and

d. are not a politically exposed person, a family member or a person known to be a close associate to a politically exposed person within the meaning of the German Anti-Money Laundering Act.

4.7. Users must maintain a payment account in their names with a CRR credit institution regulated in the EU (except: Malta and Cyprus) or EEA and must specify this account in the registration process or anti-money laundering identification process, respectively. For companies as users, it is additionally permitted to maintain a payment account with a deposit credit institution from Switzerland, provided that equivalent prevention standards under anti-money laundering law are observed. Payments by users in connection with the Issue and on the OTC Trading Platform must be made from this payment account.

4.8. When registering on the Platform, the user is obliged to provide all information on his personal data truthfully, in particular, as to the identification in accordance with the German Anti-Money Laundering Act. If false personal data is provided, Publity reserves the right to exclude users from using the Platform at any time, without notice and without prior notification. If the due diligence obligations

under anti-money laundering law cannot be fulfilled, the business relationship may be terminated for good cause without notice by Publity or with regard to the contractual relationship with Bankhaus Scheich by Bankhaus Scheich.

4.9. The data collected in the course of registration and identification is also processed for any payments (in particular, for tax purposes) that at the instigation of the Trustee of the PREOS Shares are for- warded to the Token Holders (in particular, dividends) and for processing the exchange of PREOS Tokens for PREOS Shares upon exercise of the right to exchange. On behalf of the person obliged to deduct church tax (Kirchensteuerabzugsverpflichteter), it should be noted that regular as well as event-related queries of the church tax liability are made to the German Federal Central Tax Office (Bundeszentralamt für Steuern). The user has a right of objection (blocking notice, Sperrvermerk) against the Federal Central Tax Office in relation to the transmission of data on religious affiliation (§ 51a para. 2e sentence 1 EStG).

4.10. Publity reserves the right to delete without prior notice registrations that were created with one-time email addresses (so-called 'disposable email addresses') as well as registrations that were not activated within four months of creation.

4.11. The visitor or user has no claim to use the Platform. Publity may, at its own discretion, refuse regis- tration without giving reasons or exclude users from using the Platform in whole or in part. This applies, in particular, if visitors or users violate applicable laws or good customs (gute Sitten) or oth- erwise behave inappropriately; in particular, racist, discriminatory, pornographic or insulting content will not be tolerated.

4.12. In order to ensure that business transactions are conducted properly, it is necessary for the user to notify any changes to his name, address, e-mail address and changes to other information and/or documents submitted for the purposes of anti-money laundering checks immediately via the inbox function of the Platform or via email at [email protected] and at geldwaesche@bankhaus- scheich.de. Publity and Bankhaus Scheich are entitled to terminate the business relationship for good cause if the risk under anti-money laundering law has increased with regard to the user.

4.13. The user is obliged to regularly check the messages received in his inbox or by email. The user must inform Publity immediately of any discrepancies and irregularities in any communications of Publity, but at the latest within two weeks following receipt.

4.14. The user himself is responsible for the secure storage of his login data in the form of the individual combination of email address and password. He must exercise every possible care and take all appro- priate precautions to ensure that unauthorized persons do not gain knowledge of his individual com- bination of email address and password. In particular, the user may not store or record, electronically or in any other form, his individual combination of email address and password together with his other documents regarding Publity. The user must choose a personal individual combination of email address and password in such a way that it cannot be easily identified by unauthorized persons (trial-and- error).

4.15. A user who has registered himself on the Platform with his email address and password may not leave the device through which the registration was made unattended. In the event of a breach of the

aforementioned code of conduct, the user shall be liable for all risks and damages associated there- with.

4.16. If the user discovers that his individual combination of email address and password has become known to unauthorized persons or that his account on the Platform has been used without authorization, he is obliged to notify Publity immediately and – if possible – to change his individual combination of email address and password without delay. If the latter is not possible, Publity will immediately upon receipt and acknowledgement of the relevant notification and after verification of identity during nor- mal business hours block the access of the user to his account until further notice.

4.17. The account of the user can be blocked by Publity at any time if unauthorized use is detected. In this case, Publity will inform the user of the steps necessary to prove beyond doubt the rightful ownership over his account, which rightful ownership is necessary to remove the block. If there is evidence of unauthorized use of the access, Publity is entitled to block the PREOS Tokens in the Wallet assigned to the user at Upvest so that a transfer of PREOS Tokens is not possible.

4.18. The user may only use content published on the Platform with the written permission of Publity.

III. Availability of the Platform

4.19. Publity endeavors to offer comprehensive availability of the Platform within the scope of what is tech- nically feasible and economically reasonable. Publity does not, however, provide any guarantee in this regard. In particular, maintenance work, security and capacity reasons, technical conditions and events outside the control of Publity may lead to the Platform being unavailable for a short or long period.

4.20. Publity reserves the right to restrict the Platform, including the associated services, in whole or in part at any time and without prior notice. Reasons for this may, but not limited to, be capacity shortages, the performance of maintenance/repair work and other technical measures. In the event of mainte- nance or repair work, the user shall be informed in an appropriate manner of the limited accessibility of the Platform.

4.21. A limitation of the accessibility and use of the Platform can be triggered due to the individual technical equipment of the user and quality. It is the responsibility of the user to ensure the technical framework conditions for the user to be able to access the Platform without restrictions. In order to use the Platform, appropriate settings on the computer of the user or cell phone may also be required, e.g. allowing the storage of cookies.

4.22. Publity is not liable for damages and other consequences that may result from a limited availability or a failure of the availability of the Platform.

§ 5 Subscription during Issue

5.1. Users can submit a binding offer to purchase PREOS Tokens online using the digital subscription form made available via the Platform ("Purchase Offer"). The details for users wishing to participate in the public offer of PREOS Tokens can be found in the German language securities prospectus which

will be made available during the subscription. For the Purchase Offer, the user must specify the investment amount and thereby the number of PREOS Tokens the user intends to purchase.

5.2. In order to successfully complete a subscription for the purchase of PREOS Tokens, users must com- plete all electronic form pages in full and truthfully during the subscription process on the Platform and click on the 'Invest with obligation to pay' button on the overview screen at the end of the sub- scription process. This triggers an offer by the user to purchase PREOS Tokens, but this does not automatically lead to the conclusion of a contract. Such a contract for the purchase of PREOS Tokens is not concluded until Publity or a third party commissioned by Publity accepts the Purchase Offer of the user.

5.3. The user will become aware of a successful allocation and the associated acceptance of his Purchase Offer via the Platform, at the latest, however, when the PREOS Tokens generated on the Ethereum blockchain are transferred to the Ethereum address assigned to the user. By submitting the Purchase Offer, the buyer waives an explicit declaration of acceptance by Publity in accordance with § 151 sentence 1 BGB.

5.4. Publity or a third party commissioned by it reserve the right to accept the Purchase Offer of the user in whole or in part.

5.5. Upon conclusion of the subscription process, the user must pay the Issue price in Euros for the number of PREOS Tokens specified in the Purchase Offer in full in accordance with the payment processing details displayed on the Platform within ten bank working days after information about the acceptance of the Purchase Offer. For payment processing, secupay AG ("Secupay"), registered with the com- mercial register of the local court of Dresden under HRB 27612, business address Goethestraße 6, 01896 Pulsnitz, a payment institution regulated under the German Payment Services Supervision Act (Zahlungsdiensteaufsichtsgesetz, ZAG), will be integrated.

5.6. Publity reserves the right to extend or shorten the offer period for the public offer. In addition, Publity reserves the right to terminate the public offer under certain circumstances at any time, even after the expiry of the offer period and until delivery of the PREOS Tokens. Any shortening or extension of the offer period for the public offer as well as any discontinuation or premature termination of the public offer will be announced on the website of Publity (www.publity.de).

5.7. Publity also reserves the right to offer the subscription for PREOS Tokens on the basis of a Purchase Offer through a private placement.

5.8. When making an investment decision, the user is fully responsible for obtaining information and re- viewing it. The user is therefore obliged to carry out an intensive review of all documents, risks and other circumstances before subscribing for PREOS Tokens, so that a decision on the subscription of a capital investment is made solely and on his own responsibility.

5.9. If valid Purchase Offers are submitted for a higher number of PREOS Tokens than are available, Publity may allocate at its sole discretion. The allotment volume and criteria are determined by Publity at its sole discretion. Publity is entitled to reduce or reject individual Purchase Offers.

5.10. If PREOS Tokens for which valid Purchase Offers have been submitted are not allocated, any excess amounts paid will be refunded to the respective users without the payment of interest.

5.11. If short sales have already occurred before PREOS Tokens are delivered to users, the respective seller alone bears the risk of not being able to fulfil the obligations entered into through a short sale by delivering PREOS Tokens in good time.

5.12. After acceptance of the Purchase Offer and payment of the Issue price, the number of PREOS Tokens allocated to the respective user will be credited to the respective user immediately. For this purpose, the PREOS Tokens generated by Publity on the Ethereum blockchain are transferred to the Ethereum address assigned to the respective user.

§ 6 OTC Trading Platform

6.1. Following the activation of the OTC Trading Platform by Publity (presumably in January 2021) and the establishment of a separate client relationship with Bankhaus Scheich, users can publish and accept buy and sell offers for PREOS Tokens on an over-the-counter basis on the OTC Trading Platform. Bankhaus Scheich will act as an investment broker (Anlagevermittler) on the OTC Trading Platform. The functionality of the OTC Trading Platform corresponds to a digital 'bulletin board'.

6.2. Users of the Platform who wish to trade on the OTC Trading Platform must have themselves activated for the OTC Trading Platform, establish a separate client relationship with Bankhaus Scheich to that end and submit the necessary declarations for the provision of information via the Internet, for the recording of telephone conversations and electronic communication and for client categorisation, as well as read and accept information from Bankhaus Scheich (special terms and conditions, broker information including conflicts of interest and information on principles of complaints handling).

6.3. Users are only permitted to trade on the OTC Trading Platform if a Wallet is used that is offered by a crypto custodian regulated under the German Banking Act, such as Upvest.

6.4. Users do not have a claim to the provision or maintenance of the OTC Trading Platform.

6.5. Users may only publish or accept offers on the OTC Trading Platform if they have the corresponding credit balance of PREOS Tokens they offer or are able to transfer the PREOS Tokens owed without delay.

6.6. Users can publish buy and sell orders for PREOS Tokens on the OTC Trading Platform. For this purpose, the users have to specify the number of PREOS Tokens they intend to buy or sell, the price per PREOS Token in Euro and the maximum offer period. The respective offer of the user ends after conclusion of a purchase contract on the OTC Trading Platform or after the expiry of the fixed offer period; users have the right to create a new offer. A user can no longer accept an expired offer. After publication of an offer on the OTC Trading Platform, a user can deactivate or modify it. If an offer is not deac- tivated, it can be accepted at any time.

6.7. Users can accept buy and sell offers for PREOS Tokens published on the OTC Trading Platform. By clicking on the button 'Buy now bindingly' or 'Sell now bindingly', a purchase contract is concluded directly between the users who have published or accepted the respective offer to buy or sell.

6.8. Bankhaus Scheich publishes buy and sell offers for PREOS Tokens from users on the OTC Trading Platform at the conditions specified by the seller or buyer. The offers are not amended by Bankhaus Scheich and are not forwarded to another trading venue. In particular, Bankhaus Scheich itself does not provide buying and selling prices. A purchase contract for PREOS Tokens is concluded solely be- tween the buyer and the seller. Neither Publity nor Bankhaus Scheich become party of the purchase contract. Neither Publity nor Bankhaus Scheich have influence on whether and under which conditions a purchase contract is concluded. The users have no claim to the conclusion of a purchase contract for PREOS Tokens against Publity or Bankhaus Scheich.

6.9. Users may only use the OTC Trading Platform adequately and in line with the system only. In partic- ular, the use of automated order-entry systems, such as so-called quote machines, and algorithmic trading systems for the publication and acceptance of buy and sell offers, as well as actions that qualify as market abuse (market manipulation and insider trading) in accordance with Regulation (EU) No 596/2014 (Market Abuse Regulation), as amended from time to time, or – in the event of non-direct applicability – would qualify as market abuse, constitute an inadequate and therefore misuse of the OTC Trading Platform. The same applies to the simultaneous placement of offers directed in the same or opposite direction, in particular, matching buy and sell offers using different access data, influencing the price determination and/or the conclusion of transactions on the OTC Trading Platform and on other trading venues by acting in a timely or simultaneous manner on the OTC Trading Platform and the other trading venue, also in cooperation with third parties, the use of access to the OTC Trading Platform for or the gaining of access to the OTC Trading Platform by committing other criminal offenses (in particular offenses against property or falsification of documents) and the automated publication or other provision of market data of the OTC Trading Platform. Bankhaus Scheich reserves the right to extraordinarily terminate the client relationship with the respective user with immediate effect and to exclude the user from the OTC Trading Platform in case of justified suspicion of inadequate use of the OTC Trading Platform in the aforementioned sense.

6.10. Payments to settle purchase contracts brokered on the OTC Trading Platform will exclusively be pro- cessed by the payment institute Secupay. The buyer pays the purchase price for the PREOS Tokens into an escrow account managed by Secupay. The transfer of the PREOS Tokens is initiated via the Platform and processed directly via the Wallets of buyer and seller. The funds paid as purchase price into an escrow account managed by Secupay are not forwarded to the seller of the PREOS Tokens until the OTC Trading Platform reports the transfer of the PREOS tokens to Secupay on the basis of the transaction traceable on the Ethereum Mainnet. At no time do Publity and Bankhaus Scheich have access to the private access keys of the users. By involving the payment trustee Secupay, it is intended to avoid that one of the parties to the purchase contract has to make advance payments and thereby take on the risk of not receiving the purchase price.

6.11. Users who conclude purchase contracts via the OTC Trading Platform have, in case of suspicion of the conclusion of the contract at conditions not in line with market conditions, especially in the case of market abuse by the counterparty or a third party, or in the event of any other complaints or objections regarding the conclusion of the contract (collectively the "Complaints") the possibility to contact the respective counterparty via the Platform in order to bring about on a bilateral basis the cancellation of the contract or any other solution. Users shall resolve Complaints on their own responsibility. Since Bankhaus Scheich and Publity are neither a party to the purchase contract nor involved in the

settlement of the purchase contracts, neither Bankhaus Scheich nor Publity assume a mediating or decision-making function in the event of Complaints. Bankhaus Scheich and Publity do not issue or make any statement or other assessment or evaluation on Complaints. Users can find information on the processing of their personal data by Publity in the separate privacy policy of Publity, which is available at www.preos-token.de.

6.12. Purchase contracts that are concluded outside the OTC Trading Platform have to be settled in the sole responsibility of the users. Secupay is not involved.

§ 7 Costs, fees, commissions

7.1. The use of the Platform is, in general, free of charge.

7.2. Users whose Purchase Offer for PREOS Tokens has been accepted in the course of the subscription shall pay the Issue price in Euros for the purchase of the PREOS Tokens indicated in the course of the subscription within 10 bank working days following the information about the acceptance of the Pur- chase Offer. Payments are made with the involvement of the payment institute Secupay.

7.3. Users bear no costs for the Wallet offered by Upvest which is allocated to them in the course of the Issue of PREOS Tokens after registration on the Platform.

7.4. For the services provided by Bankhaus Scheich in relation to the conclusion of transactions on the OTC Trading Platform, each contracting party (i.e. both buyer and seller of the transaction) pays a trans- action fee. This transaction fee is due upon the successful conclusion of a purchase contract for the PREOS Tokens on the OTC Trading Platform. The amount of the transaction fee is disclosed on the OTC Trading Platform. Payments of the transaction fee are made utilizing the payment institute Se- cupay which is integrated on the Platform. There is an internal agreement between Publity and Bankhaus Scheich on how both parties are remunerated for their share of the service. The transaction fee is due to Bankhaus Scheich and is therefore received and paid to Bankhaus Scheich by Publity (possibly together with other fee components), which as Platform operator acts as an outsourcing company of Bankhaus Scheich with regard to the OTC Trading Platform, utilizing the payment institute Secupay. The user agrees, anyhow, that Bankhaus Scheich may retain the payments made to them, as long as the acceptance of payments and/or remuneration is done in accordance with the law (es- pecially § 70 WpHG). Insofar the user agrees that the remuneration is to remain with Bankhaus Scheich and is not to be transferred to the user according to §§ 675, 667 BGB and § 384 HGB (if applicable).

7.5. Publity reserves the right to offer further services with a related remuneration and/or fee in the future; this will be announced by Publity on the website in an appropriate manner in each individual case and, if necessary, stipulated in additional terms and conditions.

§ 8 Privacy

8.1. Within the business relation, Publity collects, stores, transmits and in any other form processes per- sonal data from users. In doing so, Publity complies with all applicable data protection laws, in partic- ular, the provisions of the General Data Protection Regulation (GDPR), the German Federal Data Pro- tection Act (BDSG) and the German Telemedia Act (TMG).

8.2. Further information and details on data protection, including the collection, transfer and other pro- cessing of personal data by Publity and the other third parties integrated into the Platform Bankhaus Scheich, Upvest, Secupay, IDnow GmbH, Sum & Substance Ltd. and PREOS Blockchain, can be found in a separate data protection declaration, which is available at www.preos-token.de. So far as these third parties are themselves responsible for processing the personal data of users, these processing operations are governed by the relevant privacy policies of these companies, which are linked in the privacy policy of Publity.

§ 9 Confidentiality

As long as the contents accessible to users in connection with the acquired capital investments as well as all information and documents which they receive in the course of acquiring, holding and managing as well as selling the capital investments are not in each case publicly accessible, they must be treated confidentially by users. This includes, in particular, all contractual documents with Publity as well as all information and documents obtained in connection with the respective capital investment.

§ 10 Limitation of liability

10.1. The liability of Publity is unlimited if the cause of the damage is based on an intentional or grossly negligent (vorsätzlich oder grob fahrlässig) breach of contract by Publity or one of the legal represent- atives or vicarious agents of Publity.

10.2. Furthermore, Publity is liable for the slightly negligent (leicht fahrlässige) violation of essential obliga- tions. Essential are obligations whose violation endangers the achievement of the purpose of the contract or whose fulfillment makes the proper execution of the contract possible in the first place and on whose compliance the users regularly rely. In this case, however, Publity is only liable for the foreseeable damage typical of the contract (vorhersehbarer, vertragstypischer Schaden). Publity is not liable for the slightly negligent breach of obligations other than those mentioned in the above sen- tences.

10.3. The above limitations of liability shall not apply in the event of injury to life, body or health, for a defect after the assumption of a guarantee for the quality of the product and for fraudulently concealed defects.

10.4. There is no liability on the part of Publity towards the users for the tax, economic or legal objectives pursued in each case, and in particular not for the success of the respective PREOS Tokens or compli- ance with forecasts made in connection with the respective PREOS Tokens.

10.5. The exclusions and limitations of liability listed above also apply to employees of Publity, their respec- tive vicarious agents and other third parties who assist Publity in the performance of the contract.

10.6. Publity assumes no liability whatsoever for the obligations of users towards other users or third parties, for example, due to non-fulfilment of contracts concluded on the OTC Trading Platform.

§ 11 Copyrights / Granting of copyrights

11.1. Publity reserves all rights to all websites (including source texts, software, layout etc.) and their con- tents. The use of these contents by the user is only permitted in accordance with these GTC. The user is expressly prohibited from any further use. Any actions that go beyond this require a prior written consent from Publity.

11.2. Copyright notices and brand names may neither be amended nor removed.

11.3. Within the Platform, links may lead to websites of other providers, for whose content Publity assumes no liability. The creation of inline or hyperlinks from other websites to websites or website content of Publity, in particular the integration or display of websites or website content of Publity in a partial window (frame), is expressly prohibited without the prior written consent of Publity.

11.4. By publishing content (in particular contributions or discussions) on the Platform, the user transfers to Publity all necessary, temporally and spatially unlimited, irrevocable and non-exclusive rights to the content for use in all media (e.g. print, mobile and online media), to store, reproduce, modify, trans- late, make accessible, forward, in whole or in part in any form (including future), and to grant these rights to third parties. This also applies beyond the end of the contract of use. The user shall only be entitled to have the contents he has posted deleted if there is an important reason for doing so.

§ 12 Contact

User inquiries can be made at the following email address: [email protected]. Inquiries will be answered within normal business hours.

§ 13 Contract period, termination

13.1. The contract of use for the Platform is concluded between Publity and the user for an indefinite con- tractual period. The user contract can be terminated by the user and Publity at any time with 15 days' notice to the end of the month. Legal rights of revocation remain unaffected.

13.2. The right to extraordinary termination for good cause remains unaffected for both parties. A good cause is especially given in case of a repeated violation of these GTC. A good cause can also already be given in the case of a one-off serious violation of the GTC, for example in the case of deception or attempted deception of Publity, Bankhaus Scheich, Upvest or other users by deliberately providing false information by a user. A good cause also exists in case of termination of the terms of use between Upvest and the user.

13.3. Each notice of cancellation must be in text form, i.e. cancellation by email is sufficient.

13.4. The termination of the contract of use for the Platform shall not affect the legal relationship with regard to the PREOS Tokens, the terms of use concerning the Wallet at Upvest and legally binding recording and documentation obligations.

§ 14 Amendment of the GTC, termination of services

14.1. Provided that the user is not unreasonably disadvantaged, Publity reserves the right to amend the GTC at any time with effect for the future for the following reasons:

a) for legal or regulatory reasons;

b) for security reasons;

c) to further develop or optimise existing features of the services offered and to add additional features (e.g. the activation of the OTC Trading Platform);

d) to take account of technical progress and make technical adjustments; and

e) to ensure the future functionality of the services offered.

The respective amended GTCs are made available to users of the Platform under www.preos-token.de.

14.2. Users will be notified of any changes within a reasonable time before the changes take effect. At the latest, however, Platform users will receive notification of the amended GTC by email fourteen (14) days before they come into effect, provided that an email address is stored in each case.

14.3. If registered users of the Platform do not object to the validity of the amended GTC within fourteen (14) days of receipt of the notification of the amendment to these GTC, the amended GTC are deemed to have been accepted by them. Publity will inform the user in the notification of amend- ment of the significance of this period and the legal consequences of any silence.

14.4. Publity may exercise its right to ordinary termination if a user objects to an amendment to the GTC offered to him by Publity.

§ 15 Final provisions

15.1. These GTC and all legal relationships between Publity and the users are subject to the laws of the Federal Republic of Germany. The contractual and business languages are German and English. In case of (i) any provision contained in the English language version of this GTC is in conflict with, or inconsistent with, any provision in the German language version of this GTC, or (ii) any provision of this GTC requires judicial interpretation, the German language GTC version of the GTC shall prevail over the English language version. The German language version can be found at: https://preos- token.de/Allgemeine_Geschaeftsbedingungen_(Plattform).pdf.

15.2. The general court of jurisdiction of Publity is determined by its registered office (Frankfurt am Main). If the user is a businessman (Kaufmann) or exercises a comparable commercial activity abroad and the business relationship is attributable to the operations of his trade, Publity may sue the user at the general court of jurisdiction of Publity or at another competent court. Publity itself can only be sued by the users named in the above sentence at its general court of jurisdiction.

15.3. If a provision of these GTC is invalid in whole or in part, the validity of the remaining provisions shall remain unaffected. The same applies if these GTC should have a gap. In this case, the parties shall replace the gap or the ineffective or void provision by a provision which corresponds to the economic purpose of the agreement and which comes as close as possible to what the parties intended.
