Both Parties confirm and agree that Bitmain may adjust the total quantity of Units of Product delivered based on the Total Rated Hashrate per Batch of 315,000 TH/s; provided, however, Bitmain represents and warrants that: (a) the Total Rated Hashrate per Batch of the Products actually delivered by Bitmain to the Purchaser shall not be less than 315,000 TH/s; (b) that the Aggregate Total Rated Hashrate of the Products actually delivered by Bitmain shall not be less than 3.78 exahash per second (“EH/s”).

1.4

Substitute Products.

After Bitmain publishes new types of Products and if Bitmain has not suspended the production of the types of Products under this Agreement, Bitmain shall continue to deliver such agreed types of Products in accordance with this Agreement and the Purchaser shall not terminate this Agreement or refuse to accept the Products on the grounds that Bitmain has published new type(s) of Products.
