Prices and Terms of Payment

3.1

The Total Purchase Price (inclusive of any tax due and payable by the Purchaser) shall be paid in accordance with the payment schedule set forth in Appendix B of this Agreement.

3.2

In the event that the Purchaser fails to fully settle the respective percentage of the Total Purchase Price before the prescribed deadlines and fails to make a written request to Bitmain no less than five (5) Business Days prior to the prescribed deadline and obtain Bitmain’s written consent, Bitmain shall be entitled to terminate this Agreement and the Purchase shall be liable for a reasonable liquidated damage (not a penalty) of [20]% of the purchase price of such batch of Products. If there are any remaining balance after deducting the liquidated damage, such remaining balance shall be refunded to the Purchaser free of any interest. If the Purchaser fails to pay the down payment on a timely basis and Bitmain has arranged production or procurement, Bitmain shall be entitled to request the Purchaser to be responsible for the loss related to such production or procurement.

3.3

The Total Purchase Price set forth in this Agreement is merely an estimate of the price and not the actual price. The actual price will be determined [15] days before the Payment Deadline for the applicable batch of Products set forth on Appendix B and with reference to the market circumstances, provided that the actual price shall not be higher than the estimated price.

3.4

Upon receipt of notification of the actual price provided by Bitmain, the Purchaser shall be entitled to three options:

(i)

continue to perform the Order of the current batch of the Product(s) with the original rated hashrate and pay the remaining amount at the actual price; or

(ii)

request Bitmain to increase the rated hashrate in equivalent to the difference in price. Under this circumstance, Bitmain shall have the right to negotiate with the Purchaser for the amount of the additional rated hashrate based on its then inventory; or

(iii)

partially or wholly cancel the Order of the current batch of Product(s).

(iv)

Under this circumstance, the Purchaser shall not claim any refund from Bitmain. If the Purchaser has made payments and there is remaining balance, such remaining balance shall be credited to the balance of the Purchaser and its affiliates. The payments for the batches that the Purchaser has cancelled cannot be used as down payments for any batch listed in this Agreement.

Furthermore, the Purchaser shall confirm in writing the result of its exercise of the options under this Clause within two (2) Business Days after Bitmain provides the Purchaser with the actual price, and if it is overdue and no agreement is reached between the Parties, the Purchaser shall be deemed to have voluntarily and irrevocably waived its option under this Clause and the Parties shall continue to perform the Order of the current batch of Product(s) with the original rated hashrate and the Purchaser shall pay the remaining amount at the actual price.

3.5

The Parties shall confirm the corresponding batch of the Product(s) of each payment before such payment is made by the Purchaser. This confirmation shall be used to determine matters where different arrangements are applicable to different batches, such as the defaults of the Purchaser and the product discount offered to the Purchaser.

3.6

The Parties understand and agree that the applicable prices of the Product(s) are inclusive of applicable bank transaction fee, but are exclusive of any and all applicable import duties, taxes and governmental charges. The Purchaser shall pay or reimburse Bitmain for all taxes levied on or assessed against the amounts payable hereunder. If any payment is subject to withholding, the Purchaser shall pay such additional amounts as necessary, to ensure that Bitmain receives the full amount it would have received had payment not been subject to such withholding.

Product Discount

Based on the sales results and sales strategy, Bitmain is willing to offer the following discount as set forth in this Clause 4 as follows:

4.1.

With respect of the signing of this Agreement, Bitmain offers the following discount to the Purchaser:

The number of months prepaid shall be calculated from the month of payment without counting the month of estimated delivery. If delivery is delayed (except for delays caused by Bitmain’s gross negligence, recklessness or willful misconduct), delayed months shall not be counted. For clarification, the payment date shall be the date as evidenced in the remittance copy of such payment, and the discount term shall be calculated when the respective amounts under this Agreement have been received by Bitmain in full and without further consideration of the remaining amount. Payment schedules may be further adjusted in accordance with the actual situations.

4.1.3.

If the Purchaser fails to make the payments on time, the discount applicable to such batch shall be cancelled.

5.5.
