Grant of Call Option for Purchasing Additional Products 1.1 Right to Purchase. Subject to the terms and conditions of this Agreement, at any time during the period from the date of this Agreement to September 30, 2024 (the “Call Option Period”), the Purchaser and the Purchaser’s Affiliates shall have the right in one or more transactions (the “Call Option”), but not the obligation, to purchase, in whole or in part, additional Products having the specifications set out in paragraph 1.1. of Appendix A (the “Forward Deliverables”) at the Call Purchase Price (as defined below). The maximum rated hashrate of the Forward Deliverables if exercising the Call Option in full shall be 9,120,000 TH/s with a total purchase price of US$127,680,000, representing US$14 per T (“Call Purchase Price”), and the maximum quantity of Forward Deliverables shall be approximately 48,000 units with the cumulative Forward Deliverables to be shipped by BITMAIN not to exceed approximately 3,000 units by June 2024, 12,000 units by July 2024, 21,000 units by August 2024, 30,000 units by September 2024, 39,000 units by October 2024 and 48,000 units by November 2024. All Forward Deliverables nominated to be shipped in a given month as per paragraph 1.4.i. of this Appendix C, whether subject to one or more Notices of Exercise (as defined below), will form a separate batch of Forward Deliverables. 1.2 Call Purchase Fee. The Purchaser shall pay BITMAIN an amount of US$12,768,000 as the consideration of the Call Option (“Call Purchase Fee”), which is calculated as 10% of the Call Purchase Price, within seven (7) days after the execution of this Agreement. In the event the Purchaser exercises the Call Option in whole, the Call Purchase Fee shall be applied in whole towards the settlement of the Down Payment of the Call Purchase Price. In the event that the Purchaser only exercises Call Option in part at the end of the Call Option Period, the Call Purchase Fee corresponding to the proportion of the quantity to be purchased by the Purchaser to 48,000 units shall be applied by the Purchaser to settle the total purchase price of Forward Deliverables, while the remaining proportion of the Call Purchase Fee shall be forfeited to BITMAIN. To further clarify, upon any exercise of the Call Option the Purchaser shall be obligated to pay the corresponding proportionate amount of the Call Purchase Price associated with the exercise of the Call Option less the corresponding proportionate amount of the Call Purchase Fee already paid to BITMAIN, according to the schedule of payment as follows: Payment Payment Percentage Payment Date Down Payment / Call Purchase Fee 10% 10% of the total purchase price of Forward Deliverables shall be paid by the Purchaser within seven (7) days after the execution of this Agreement. For the avoidance of doubt, the payment of the Call Purchase Fee satisfies the Down Payment requirements for all Forward Deliverables. Interim Payment 40% 40% of the total purchase price of Forward Deliverables shall be paid at least one (1) month prior to the first day of the Shipping Period of Call Purchase (as defined below) of such batch of Forward Deliverables Balance Payment 50% 50% of the Call Purchase Price of each batch of Forward Deliverables shall be paid at least seven (7) days prior to the first day of the Shipping Period of Call Purchase of such batch of Forward Deliverables 1.3 A request to cancel such Call Option or refund any part of Call Purchase Fee would not be entertained by BITMAIN.

Page 21 of 21 #98810024v3 1.4 Procedure. 1. In the event the Purchaser desires to exercise the Call Option to purchase any Forward Deliverables, whether in one or more transactions, or in whole or part, the Purchaser shall deliver to BITMAIN during the Call Option Period one or more written, unconditional, and irrevocable notices of exercise (each a “Notice of Exercise”) which shall specify: (a) the time period when BITMAIN shall deliver or ship the applicable batch of Forward Deliverables on condition that the Purchaser has fulfilled its payment of corresponding proportionate amount of the Call Purchase Price associated with the exercise of the Call Option hereunder (“Shipping Period of Call Purchase”); (b) the quantity and total rated hashrate of the applicable batch of Forward Deliverables; and (c) a shipping address or its intention to self-pick up the Forward Deliverables in a manner as agreed by the Parties. The Parties agree that BITMAIN shall deliver or ship the Forward Deliverables contemplated in any Notice of Exercise only after June 1, 2024, and in any event the Shipping Period of Call Purchases shall not be earlier than 60 days from of date of the receipt by BITMAIN of the applicable Notice of Exercise. ii. The Parties agree that the shipping of the Forward Deliverables shall be completed in accordance with the procedure as set forth in Clause 4 of this Agreement, and the Forward Deliverables shall be subject to all other applicable terms and conditions of this Agreement regarding Products, including but not limited to Clause 5 Customs, Clause 6 Warranty and Appendix A, unless otherwise specified in this Appendix C. 1.5 Cooperation. The Purchaser and BITMAIN shall take all actions as may be reasonably necessary to consummate the purchase of any Forward Deliverables pursuant to this Appendix C. 1.6 Constriction. Notwithstanding the foregoing, in the event that Purchaser fails to fully pay the respective percentage of the Total Purchase Price with respect to any applicable batch of Products before the prescribed deadline(s) set forth in Appendix B of this Agreement without BITMAIN’s prior written consent and has failed to remedy such payment failure within fifteen (15) days of written notice from BITMAIN to Purchaser, then without prejudice to any other rights and remedies that BITMAIN may have under this Agreement or otherwise, the Parties agree that the Call Option shall not be exercised and shall immediately become of no effect without any penalty to BITMAIN, unless such default is waived by BITMAIN.
