Data storage and Sellers Agreement

PART A - Contractual Framework and Cooperation

Preamble

Hahnemühle FineArt GmbH, Hahnestraße 5, 37586 Dassel, Germany (hereinafter referred to as "Hahnemühle"), is a renowned paper manufacturer that produces and distributes high-quality artist papers for photography, digital art, and art reproductions.

Building on its long-standing tradition and expertise in fine art printing, Hahnemühle has developed the My Art Registry (MAR 2.0) platform, a digital ecosystem designed to connect artists, certified print studios, and collectors through a secure and transparent workflow.

The MAR 2.0 platform provides artists with the opportunity to securely store, authenticate, present, and sell their artworks as fine art prints on certified Hahnemühle papers or as NFT-based digital artworks. The production of fine art prints is carried out under the print-on-demand principle, meaning that each print is produced only after a buyer has concluded a purchase agreement online and paid the corresponding purchase price in full.

All production of physical artworks takes place exclusively at Hahnemühle Certified Print Studios, each of which holds the "Certified Studio Platinum" status, ensuring that every print meets Hahnemühle's highest quality standards. Each fine art print produced through MAR 2.0 is equipped with a Hahnemühle hologram and accompanied by a Certificate of Authenticity (COA) bearing a unique identification number. Together, these form a tamper-proof authentication system for verifying the origin and authenticity of the artwork.

Within this framework, Hahnemühle provides artists with a digital storage and management service known as the Fine Data Storage Solution. This service allows artists to upload and securely store their high-resolution image files, metadata, and associated artwork information in preparation for sale on the MAR 2.0 platform. It also facilitates automated data transfer to the Certified Print Studio selected by the buyer during the order process.

The sale and purchase of artworks via the MAR 2.0 platform are governed by the General Terms and Conditions of Sale MAR 2.0, which define the rights and obligations of the artist and buyer. These Terms form an integral part of the overall contractual structure between the Artist, Hahnemühle, and the Buyer.

Hahnemühle itself does not become a contracting party to any purchase agreements concluded between artists and buyers. Instead, Hahnemühle acts solely as the platform operator, intermediary, and collection service provider, ensuring the technical, logistical, and financial coordination between the parties involved.

The MAR 2.0 platform is currently in its beta testing phase, which runs until 16 March 2026. During this period, artists may participate under preferential conditions as part of the pilot group. This agreement governs the rights and obligations of the contracting parties during the beta phase and—should the artist exercise the option right under Article 14.2—beyond this period.

Article 1 — Object of the Contract

1.1 Purpose and subject matter

1. The purpose of this contract is to regulate the rights and obligations of the contracting parties in connection with the use of the Fine Data Storage Solution and the technical integration of the Artist's artworks into the MAR 2.0 platform operated by Hahnemühle FineArt GmbH.
2. The Fine Data Storage Solution provides the Artist with a secure digital environment for the upload, management, and long-term storage of high-resolution artwork data, associated metadata, and related documentation necessary for presentation and sale through the MAR 2.0 platform.

1.2 Relationship to the General Terms and Conditions of Sale MAR 2.0

1. The sale of artworks to buyers via the MAR 2.0 platform, including the conclusion of purchase contracts, production, delivery, and buyer rights, is governed exclusively by the General Terms and Conditions of Sale MAR 2.0 (hereinafter "GTC MAR 2.0").
2. Those terms form an integral part of the contractual framework between the Artist, Hahnemühle, and Buyers. In the event of any inconsistency between this contract and the GTC MAR 2.0 concerning sales transactions, the provisions of the GTC MAR 2.0 shall prevail.

2. The Artist is the data owner and seller of the artworks offered via the MAR 2.0 platform. The Artist alone is responsible for the content, legality, and authenticity of all artworks and information uploaded to the system.
3. Certified Print Studios act as independent production partners that reproduce artworks on behalf of the Artist under the print-on-demand model and in accordance with Hahnemühle's quality standards.

Article 11 - NFT Artworks

11.1 Option to Offer NFT Artworks

1. The Artist may offer digital image files stored in the Fine Data Storage Solution as NFT Artworks via the MAR 2.0 platform. This offer may be made in addition to, or instead of, an offer for the sale of a fine-art print.
2. All conditions and data requirements set out in Article 9 (Sales Offer via MAR 2.0) and Article 10 (Purchase and Use of Certificate of Authenticity Kit) apply correspondingly to NFT Artworks.

11.2 Prerequisites for Offering NFT Artworks

1. Before listing an NFT Artwork, the Artist must:
   1. possess a verified digital wallet compatible with the blockchain network used by MAR 2.0 (currently Ethereum / ETH);
   2. link that wallet to the Artist's MAR 2.0 account through the secure interface provided; and
   3. purchase or assign a valid Certificate of Authenticity Kit as described in Article 10.
2. Each NFT Artwork offered for sale must correspond to a single certificate number already registered in the MAR 2.0 database.

11.3 Currency, Pricing, and Payouts

1. NFT Artworks are offered in the cryptocurrency Ethereum (ETH).
2. The Artist specifies the net payout amount he or she wishes to receive after deduction of Hahnemühle's commission and applicable VAT. The net payout amount for NFT Artworks may not fall below EUR 10,000 (net) or its equivalent in ETH.
3. The MAR 2.0 system automatically converts and displays the total gross purchase price payable by the buyer in ETH, incorporating Hahnemühle's commission and statutory VAT.
4. Payments, conversions, and payouts follow the automated procedures integrated into the MAR 2.0 payment infrastructure. Hahnemühle acts as a collection service provider in accordance with the GTC MAR 2.0.

11.4 Minting and Transfer of Ownership

1. Upon conclusion of a purchase contract for an NFT Artwork, the corresponding NFT token is minted on the designated blockchain and transferred to the buyer's registered wallet.
2. The token references the artwork's metadata, including its COA number, edition data, and the Artist's identity.
3. The buyer thereby acquires ownership of the NFT token only; all intellectual-property rights in the underlying artwork remain with the Artist in accordance with Article 9 of the GTC MAR 2.0.

11.5 Data Integrity and Security

1. All blockchain transactions are executed through Hahnemühle's verified smart-contract infrastructure.
2. The Artist must ensure that the linked wallet is properly secured and that private keys or access credentials are not disclosed to third parties. Hahnemühle assumes no responsibility for loss of access to wallets or tokens caused by the Artist's negligence.

11.6 Authenticity and Verification

1. Each NFT Artwork is linked to a verified Certificate of Authenticity (COA) and its unique hologram number.
2. Hahnemühle validates this linkage before the NFT Artwork is released for sale. Until verification is complete, the listing remains unpublished, which is visible only to the Artist.

11.7 Prohibited Uses

1. The Artist may not mint or offer identical or substantially similar NFTs of the same artwork on any platform outside MAR 2.0 during the term of this contract and for twelve (12) months thereafter.
2. The Artist may not transfer or sell NFT tokens privately or through unauthorized intermediaries outside the MAR 2.0 system.

Article 12 - Order of Publications

12.1 Display Sequence of Artworks

1. Artworks offered for sale by the Artist on the MAR 2.0 platform are displayed according to a publication sequence that prioritizes the most recently uploaded or newly activated listings.
2. Accordingly, the newest artworks added by the Artist are shown first in the Artist's portfolio and, by default, appear in chronological order of publication in the publicly visible gallery view.

12.2 Search and Sorting Options

1. The MAR 2.0 platform may also display artworks based on dynamic factors such as search relevance, filters selected by users, or curated promotional placement determined by Hahnemühle's algorithm.
2. Such dynamic arrangements serve to improve user experience and visibility but do not alter the chronological order within the Artist's individual portfolio.

12.3 No Entitlement to Specific Placement

The Artist acknowledges that the display sequence and visibility of artworks may vary due to search parameters, browser settings, or marketing campaigns on the platform. The Artist has no legal entitlement to a fixed or prioritized position beyond the standard chronological publication order.

1. If the Artist breaches the exclusivity obligation, Hahnemühle remains entitled to receive the commission that would have accrued had the sale been made via MAR 2.0.
2. Further claims for damages or injunctive relief remain unaffected. Hahnemühle may also deactivate or suspend the Artist's account in accordance with Article 19 (Deactivation of Sales Offers).
