2. PAYMENT TERMS, FEES, AND TAXES

2.1. UPFRONT FEES This Agreement and the provision of Services agreed to herein are subject to the Customer’s satisfaction of an upfront payment of a fixed amount, set in US Dollars for the given hash rate (“Upfront Fees”). The company ECOS Mining Group-M doesn’t accept payments in cryptocurrencies and doesn’t conduct exchange operations. These operations are fulfilled with the help of partners. 2.2. CLOUD MINING SERVICE FEES The Customer shall pay and owe ECOS Mining Group-M certain data center operations service fees (“Service Fees”) for use of the Services as described in this Agreement. ECOS Mining Group-M shall calculate and automatically deduct the Service Fees from Customer’s Hash Rate Output on a daily basis. Service Fees are indicated in contracts per 1 unit of computational power for one day of contract operation. So the Service Fees of a particular contract is calculated by multiplying the amount of computational power unit by service fee rate, defined in the contract. In the event that the Hash Rate Output for one or more days does not satisfy the Service Fees ECOS Mining Group-M may deduct the Service Fees from any subsequent Hash Rate Output during the Term of the Agreement and / or consider the specified Fee as the Customer’s debt for the provided and received Services that the Customer is obliged to pay. Service fee is subject to unilateral change by ECOS Mining Group-M. 2.3. BLOCKCHAIN TRANSACTION FEES The delivery and receipt of any of the Customer’s digital assets is subject to network or transaction fees charged by the blockchain associated with the Customer-selected algorithm (“Blockchain Transaction Fees”). Blockchain Transaction Fees are paid to emit, record, verify, and process a transaction on the blockchain and not retained by ECOS Mining Group-M. 2.4. THIRD-PARTY FEES Certain digital wallets, wallet addresses, tools, and third-party software and devices (“Third-Party Wallets”) used by the Customer may also charge Customer a fee, including a per transaction or transfer fee. Customer is responsible for being aware of and satisfying any such fee. Customer should note that any such fees may significantly reduce Customer’s Hash Rate Output and therefore Customer is responsible for managing the selection, use, and rate and frequency of their delivery of Hash Rate Output to any such Third-Party Wallets. 2.5. TAXES The Customer is responsible for any taxes, and the Customer will pay ECOS Mining Group-M for Services without any reduction for taxes. If ECOS Mining Group-M is obligated to collect or pay Taxes, Taxes will be invoiced to the Customer and/or deduced from the Customer’s Hash Rate Output, unless the Customer provides ECOS Mining Group-M with a timely and valid tax exemption certificate authorized by the appropriate taxing authority. In some countries, states, and provinces, the sales tax is due on the total purchase price at the time of sale and must be invoiced and collected at the time of the sale.

3. CUSTOMER OBLIGATIONS

3.1. ALGORITHM SELECTION The Customer is responsible for the selection of the algorithm and understands and accepts the risks associated with blockchain technologies, cryptographic currencies, and digital asset extraction. 3.2. HASH RATE ALLOCATION The Customer is responsible for the allocation of the Customer’s hash rate purchased under this Agreement. The Customer acknowledges that ECOS Mining Group-M is not responsible for the selection or timing of Hash Rate Output to be mined under this Agreement and protocols selected for use in connection with the Services. The Customer shall monitor and allocate hash rate through the Dashboard. The Customer acknowledges that the difficulty of digital assets extraction may vary and will likely increase during the Term of this Agreement and Customer shall monitor, supervise, and determine which digital assets to mine under this Agreement. 3.3. DIGITAL WALLET AND PRIVATE KEYS The Customer represents and warrants that the Customer is familiar with and accepts the risks associated with digital wallets and private keys, including the risks described in this Section 3.3. The Customer’s digital wallet or vault may require a private key, or a combination of private keys, for access. Accordingly, loss of requisite private key(s) associated with the Customer’s digital wallet or vault storing Hash Rate Output will result in loss of such Hash Rate Output, access to the Customer’s Hash Rate Output balance and/or any initial balances in blockchains. Moreover, any third-party that gains access to such private key(s), including by gaining access to login credentials of a hosted wallet or vault service the Customer uses, may be able to misappropriate the Customer’s digital assets. ECOS Mining Group-M is not responsible for any such losses. 3.4. LOG-IN CREDENTIALS The Customer represents and warrants that the Customer is responsible for the preservation of confidentiality of the Customer’s login credentials. ECOS Mining Group-M log-in credentials generated by the Services are for the Customer’s internal use only and the Customer is strictly prohibited from selling, transferring, or sublicensing them to any other entity or person. 3.5. BLOCKCHAIN NETWORK RISK The Customer represents and warrants that the Customer accepts the risks of blockchain protocol and network, including instability, congestion, high transaction costs, network latency, information security, regulatory risk, and technological and operational error. The Customer understands that these risks may result in delay or failure to process transactions, failure to deliver Hash Rate Output, and high Blockchain Transaction Fees. The Customer represents that Customer understands and agrees that the Company is not responsible for any diminished Services, related features, or capabilities resulting from blockchain network risk. As provided in Section 1.4 (Hash Rate Output), in the event of a material increase or decrease to Blockchain Transaction Fees or operational degradation, congestion, failure or disruption otherwise of the blockchain network used by Customer, the Company may, at its sole discretion and upon notice to the Customer, increase or decrease the threshold to deliver the Customer’s Hash Rate Output. 3.6. BLOCKCHAIN MODIFICATION RISK The Customer represents and warrants that the Customer is familiar with and accepts the risks associated with blockchain development and code changes, including the risks described in this Section 3.6. Blockchain technologies are still under development and may undergo significant changes over time. Blockchain developers may make changes to features and specifications of the algorithm selected by the Customer. Such changes may include or result in the elimination for support for and/or the efficient use of chips used by ECOS Mining Group-M. In addition, blockchain developers may also determiner to modify the cryptographic verification process such that the blockchains can no longer be verified through proof-of-work and instead adopt proof-of-stake methodologies. 3.7. PROOF-OF-WORK REPLACEMENT RISK In addition to blockchain modification risk, blockchain developers may also determine to modify the cryptographic verification process such that the blockchains can no longer be verified through proof-of-work and instead adopt proof-of-stake methodologies.
