AGREEMENT

1.Description of the Miners.
1.1.General.  The models, specifications and applicable performance parameters of the Miners (the “Miner Specifications”), and the Purchase Order Total Price (as defined in Section 3.2) to be paid therefor, shall be set forth on each Purchase Order (as defined in Section 3.1) entered into between the Parties during the Term (as defined in Section 2.1).    
1.2.Initial Purchase Order.  The initial Purchase Order to be executed by the Parties, regarding the purchase and sale of eight thousand, three hundred twenty (8,320) model M56S+ Miners at [****] and [****]/100 Dollars ($[****]) per terahash (“TH”), and twenty four thousand, nine hundred sixty (24,960) model M56S++ Miners at [****] and [****]/100 Dollars ($[****]) per TH, as more particularly described on Appendix 3.1.2 attached hereto and incorporated by this reference herein (the “Initial Purchase Order”), shall be executed simultaneously with this Agreement.  Except with respect to the Initial Purchase Order, Riot does not commit to purchasing any certain quantity of Miners by entering into this Agreement.
1.3.M56S++ Purchase Option.  MicroBT hereby grants to Riot, and Riot hereby accepts, the option to purchase from MicroBT up to a total of sixty-six thousand, five hundred sixty (66,560) model M56S++ Miners, pursuant to one (1) or more Purchase Orders executed hereunder, at a maximum price of $[****]/TH (the “Purchase Option”) during the Option Period (as defined herein).  Riot is entitled to


exercise the Purchase Option at any time until December 31, 2024 (the “Option Period”).  The Purchase Option shall be subject to the terms of Section 3.3.  Upon Riot’s delivery of written notice of its election to exercise the Purchase Option, which notice shall include the number of model M56S++ Miners to be purchased, the Parties shall execute a Purchase Order for such Miners as soon as reasonably practicable thereafter (but in any event no later than five (5) business days after the date Riot delivers such notice to MicroBT).  MicroBT shall guarantee sufficient production of model M56S++ Miners for the duration of the Option Period, or it shall otherwise extend the price of $[****]/TH, subject to Section 3.3, to replacement model Miners having hashrate, power draw and power efficiency ratings at least equivalent to those of the model M56S++ Miners, as specified in Appendix 3.1.2.
1.4.New Miner Models.  The Parties acknowledge that MicroBT may release new Miner models during the Term.  In such event, MicroBT shall promptly notify Riot, in writing, of such new Miner releases and provide Riot the opportunity to purchase such new model Miners, according to this Section 1.4.  Within fourteen (14) days (or other such period of time as may be agreed to by the Parties in writing) of Riot’s receipt of such notice, Riot, if it desires to purchase such new model Miners, shall deliver written notice to MicroBT, specifying the quantity of such new model Miners Riot intends to purchase from MicroBT.    Following receipt of Riot’s notice to MicroBT of its intent to purchase such new model Miners, the Parties shall negotiate in good faith the terms and conditions of the Purchase Order covering the purchase and sale of such Miners, at prices subject to Section 3.3, and, for a period of at least ninety (90) days after its receipt of Riot’s notice, MicroBT shall reserve for purchase by Riot a sufficient quantity of such new model Miners to supply Riot’s desired purchase, as specified in its notice.
1.5.Production.  All Miners covered by this Agreement shall be manufactured and produced within the United States of America, either directly by MicroBT or through its USA-based contract manufacturer(s), at MicroBT’s discretion.  Upon delivery in accordance with Section 4, MicroBT shall certify to Riot that the Miners to be delivered to Riot in the applicable Batch (as defined in Section 4.1) have been manufactured in the USA in accordance with this Section 1.5.  Additionally, MicroBT shall be responsible for ensuring upstream compliance with all applicable laws, rules and regulations governing the labor, minerals, components and parts used in the Miner manufacturing process, and shall indemnify and hold Riot harmless from any violations of application law with respect thereto.  Further, during the Term, Riot shall be permitted, upon no less than ten (10) days’ written notice, to freely inspect MicroBT’s production facilities used to produce the Miners sold to Riot.  
2.Term and Termination.
2.1.Term.  The initial term of this Agreement shall commence as of the Effective Date and continue until the later of: (x) the end of the thirtieth (30th) month following the Effective Date (i.e., December 31, 2025); and (y) the end of the production and delivery schedule of any Purchase Order executed under this Agreement (the “Term”); provided, however, that the Parties may terminate this Agreement earlier (a) by mutual written agreement of the Parties, (b) upon written notice by the non-breaching Party upon material breach hereof by the other Party (as described in Section 2.2), or (c) as permitted under Section 9.3.  For the avoidance of doubt, the Parties hereby acknowledge and agree that the expiration of the Term shall have no effect on the Parties’ obligations to complete any outstanding Purchase Orders entered into prior to the expiration of the Term, and the terms of this Agreement shall remain in full force and effect with respect to such Purchase Orders.  The Parties may agree, by a written instrument signed by both Parties, to extend the Term, on such terms and conditions as reasonably agreed by the Parties.
2.2.Termination for Material Breach.  Notwithstanding Section 2.1, either Party may terminate this Agreement, upon thirty (30) days’ advance written notice to the other Party, due to the other Party’s material breach of its obligations, representations, warranties or covenants under this Agreement; provided,

Page 2 of 14


however, if, based on the non-breaching Party’s commercially reasonable determination, the breach is capable of being cured within thirty (30) days, the non-breaching Party shall allow the breaching Party such thirty (30) day period after the date the non-breaching Party delivers notice, to cure its breach(es) of this Agreement, and, if so cured, this Agreement shall not terminate and shall continue in full force and effect as if such breach(es) had not occurred.  Notwithstanding the foregoing, in the case of MicroBT’s breach of its representations or warranties set forth in Sections 5.2.3 through Sections 5.2.6, Riot may terminate this Agreement effective immediately upon delivery of written notice to MicroBT.  For the avoidance of doubt, termination by a Party as permitted under this Section 2.2 shall not reduce or limit the breaching Party’s liability, or the non-breaching Party’s other remedies, as provided under this Agreement.
3.Purchases, Payments and Invoicing.
3.1.Purchase Order Process.  Both Parties acknowledge and agree that Miner Specifications, purchase quantities and prices shall, to the extent not identified in this Agreement, be specified on an order-by-order basis.  During the Term, Riot may submit to MicroBT a purchase order document, in the form attached as Appendix 3.1.1 hereto (each, a “Purchase Order”), the terms of which shall be agreed upon by the Parties and which shall be executed by an authorized representative of each Party (or a subsidiary of such Party pursuant to the following sentence).  The Parties may enter into Purchase Orders through their respective USA based, wholly owned subsidiaries as indicated in each such Purchase Order.  The Parties have entered into, as of the Effective Date, the Initial Purchase Order, attached hereto as Appendix 3.1.2, which is incorporated by this reference herein, as if set forth in this Agreement in full.  Thereafter, each subsequent Purchase Order, as may be executed from time to time by the Parties during the Term, shall incorporate this Agreement by reference as if fully set forth therein.  In the event of a conflict between the terms of this Agreement and the terms of any Purchase Order, the terms of the Purchase Order shall prevail.  Each Purchase Order shall include, at a minimum:
3.1.1.the applicable Miner Specifications;
3.1.2.the Miner quantity to be delivered;
3.1.3.the Delivery Date(s) (as defined in Section 4.1);
3.1.4.the applicable supplemental terms and conditions (if any, and as agreed upon by the Parties); and
3.1.5.the Purchase Order Total Price (as defined in Section 3.2).
3.2.Purchase Order Total Price.  The maximum price to be charged by MicroBT to Riot in exchange for delivery of the Miners specified under any Purchase Order, exclusive of applicable taxes, fees, premiums, and other sums payable as permitted by this Agreement, shall constitute the total Purchase Order price, as indicated on the applicable Purchase Order (the “Purchase Order Total Price”).  The Purchase Order Total Price represents the aggregate of the price per terahash (TH) of the Miners purchased by Riot pursuant to the applicable Purchase Order, inclusive of MicroBT’s standard volume discount offered to customers in the ordinary course of its business, according to the quantity of Miners sold (the “price per TH”), multiplied by the total rated hashrate of such Miners, subject to adjustment pursuant to Section 3.3.2 for actual hashrate delivered with respect to such Purchase Order.  [****].  For the avoidance of doubt, MicroBT shall apply to any such Purchase Order the best volume discount corresponding to the quantity of Miners to be delivered under the Purchase Order, as offered by MicroBT to any other customer during the six (6) months immediately preceding the date of such Purchase Order.  The Purchase Order Total Price shall constitute a “fixed price” subject to adjustment, as set forth in Section 3.3, as well as any additional amounts due pursuant to Sections 3.4 and 3.5, subject to the Parties’ agreement in the applicable Purchase Order.

Page 3 of 14


3.3.Purchase Price Adjustments.  The Purchase Order Total Price, including the price per TH of the Miners purchased and sold pursuant to a Purchase Order executed hereunder are subject to adjustment as set forth in this Section 3.3:
3.3.1.[****].    
3.3.2.The Parties acknowledge and agree that the actual hashrate delivered, on a per Miner basis, is subject to fluctuations within acceptable parameters.  If, however, the aggregate hashrate of the Miners accepted by Riot in accordance with Section 4.2, is, on a per Batch basis: (A) greater than [****] percent ([****]%) of the aggregate rated hashrate of such Batch stated in such Purchase Order (subject to the [****] percent ([****]%) performance guarantee set forth in Section 5.2.2 with respect to target Miner Specifications) (“Overdelivery”); or (B) less than [****] percent ([****]%) of the aggregate rated hashrate of such Batch stated in such Purchase Order (“Underdelivery”), then, the Purchase Order Total Price shall be adjusted to reflect the actual hashrate delivered in such Batch, according to the agreed price per TH set forth in the applicable Purchase Order, as adjusted hereunder.    
3.3.3.Any adjustments made pursuant to Section 3.3.1 (with respect to the base price per TH) or Section 3.3.2 (with respect to Underdelivery) shall be recorded as credits against future amounts due under the applicable Purchase Order, with any excess held in reserve as a freely tradable credit against any future purchases by Riot of Miners from MicroBT (whether under this Agreement or otherwise).   For the avoidance of doubt, with respect to any such adjustment, Riot shall not be required to make any additional payments under the applicable Purchase Order until the credit accrued to Riot as a result of such adjustment is reduced to zero, and any credited amount remaining after reducing the remaining Purchase Order Total Price to zero shall be held as a freely tradable credit by Riot, in an account designated for Riot with MicroBT.  At Riot’s request, MicroBT shall facilitate the transfer (including pursuant to a sale) by Riot of any such credit to any person designated by Riot.  Riot and MicroBT shall use commercially reasonable efforts to effect any such transfer within three (3) business days of Riot’s request.
3.3.4.Any adjustments made pursuant to Section 3.3.2 (with respect to Overdelivery) shall be made at the final Batch delivery and acceptance under the applicable Purchase Order, such that, if, after applying any credits due to Riot in accordance with Section 3.3.3, any amounts remain due and outstanding to MicroBT from Riot under such Purchase Order, Riot shall pay any such remaining balance due on the as-adjusted Total Order Purchase Price to MicroBT within three (3) business days of end of the final Acceptance Period with respect to Miners delivered to Riot under such Purchase Order.  
3.4.USA Production Premium.  Riot shall pay to MicroBT a premium charge (the “Production Premium”), in an amount not to exceed [****] and [****]/100 Dollars ($[****]) per Miner, to compensate MicroBT for increased production costs due to the requirement that the Miners are produced in the USA.  The Parties acknowledge their expectation that the cost of USA production is expected to decline over time, and, as such USA production costs are so reduced, MicroBT shall correspondingly reduce the Production Premium per Miner charged to Riot.  For the avoidance of doubt, this Production Premium shall be payable in addition to the Purchase Order Total Price.  Further, the Production Premium for any Purchase Order shall not be aggregated into the Purchase Order Total Price, charged or otherwise become payable, until the applicable Balance Payment (as defined in Section 3.6.3) becomes due.  
3.5.Taxes, Duties and Fees.  Riot acknowledges that it is responsible for all transactional taxes levied by a governmental authority with taxing jurisdiction upon the delivery of Miners purchased by Riot pursuant to each Purchase Order executed hereunder; provided, however, that tax compliance is the

Page 4 of 14


responsibility of MicroBT and MicroBT shall properly collect from Riot the applicable transactional tax amounts by including such taxes as a separately stated line-item on the final invoice for the Balance Payment due upon delivery of each Batch of Miners delivered to Riot pursuant to the applicable Purchase Order.  Riot shall pay such invoiced amounts in accordance with Section 3.8, and MicroBT shall remit such taxes directly to the appropriate taxing authority following collection, in accordance with applicable law.  Notwithstanding the foregoing, Riot shall be solely responsible for collecting and paying any Texas Sales or Use Tax due on the purchase, sale, delivery and/or use of the Miners in Texas, and MicroBT shall not be required to, no shall it make any attempt to, collect such taxes.  For the avoidance of doubt, Riot shall solely be responsible for taxes, duties, excises and governmental duties and fees levied upon the final purchase, sale, and delivery of the Miners in accordance with Section 4, and Riot shall not be responsible for any import/export taxes, duties or fees, taxes, or other excises levied against any portion of MicroBT’s supply chain prior to ultimate delivery of the Miners to Riot.  Further, MicroBT shall not collect from Riot tax amounts assessed by virtue of compensation paid by Riot to MicroBT hereunder, including but not limited to, any federal, state or local income tax resulting from transactions entered into hereunder, for which MicroBT is solely responsible.  MicroBT agrees to defend, indemnify, and hold harmless Riot from and against any and all losses, damages, claims, penalties, and litigation arising out MicroBT’s failure to properly collect and remit necessary tax amounts in accordance with these terms and conditions.
3.6.Standard Payment Terms.  The Parties may negotiate payment terms with respect to any Purchase Order, which terms shall be indicated therein.  When the Parties do not specify payment terms in a Purchase Order, the following standard payment terms shall apply to the Purchase Order and each corresponding Batch (as defined in Section 4.1) delivery specified therein:
3.6.1.Thirty percent (30%) of Purchase Order Total Price due seven (7) business days after Purchase Order execution (the “Deposit”);
3.6.2.Forty percent (40%) of the portion of the Purchase Order Total Price attributable to the corresponding Batch due within three (3) months before that Batch’s Delivery Date (as defined in Section 4.1) set forth in the Purchase Order (each, a “Progress Payment”); and
3.6.3.Thirty percent (30%) of the portion of the Purchase Order Total Price attributable to the corresponding Batch due within two (2) business days of that Batch’s Delivery Date set forth in the Purchase Order (each a “Balance Payment”).
3.7.Credits.  Any Deposits and other amounts paid by Riot under this Agreement shall be credited toward subsequent amounts due by Riot hereunder until the amount of the Deposit is reduced to $0.00, with such credit first being applied against the total Purchase Price due with respect to the applicable Purchase Order under which such amounts were paid, and, thereafter, against the total Purchase Price of any future Purchase Orders executed hereunder.
3.8.Invoices.  MicroBT shall invoice Riot for each Deposit, Progress Payment and Balance Payment incurred under each Purchase Order.  MicroBT shall direct its invoices to [****].  Payments shall be made via T/T Wire transfer, in United States Dollars ($USD), payable to the Party’s predesignated bank account in accordance with this Agreement’s terms and conditions. Riot shall pay undisputed invoiced amounts to MicroBT within fourteen (14) days of its receipt of MicroBT’s invoice.  The Parties shall reasonably cooperate to resolve any disputed invoices as soon as possible, but in any event within thirty (30) days of the date such invoice is delivered to Riot.  Any unresolved disputes regarding invoices shall be submitted to an independent certified public accountant firm of the Parties’ choosing, with each Party selecting an independent certified public accountant firm if the Parties are unable to agree, and, in such event, with such independent certified public accountant firms selecting a third independent certified public accountant firm to act as a tie-breaker.

4.1.Delivery.  MicroBT shall deliver its Miners in a series of tranches (each, a “Batch”) on or before the fifteenth (15th) day of the month in which a specified Batch is to be delivered (the “Delivery Date”) pursuant to the monthly delivery schedule set forth in the applicable Purchase Order.  Deliveries shall be made Ex-Works (Incoterms 2020) at the facility designated by MicroBT in the applicable Purchase Order, in MicroBT’s commercially reasonable discretion; provided, however, that such facility must be (a) located within the United States of America and (b) either (i) within MicroBT’s control or (ii) controlled by an entity sharing common ownership and control with MicroBT (for the avoidance of doubt, this may include any contract manufacturing facility located in the USA utilized by MicroBT to fulfill the production of Miners hereunder).  MicroBT is responsible for properly packaging the Miners, including their accessories and spare parts, and taking all necessary packaging measures such as waterproofing, moisture proofing and anti-collision packaging to ensure the safe transportation of the Miners, and shall make the Miners available for pick-up by Riot on or before the applicable Delivery Date.  Riot shall be responsible for all additional logistical matters including the pick-up and transportation of the Miners from MicroBT’s facility to Riot’s facility at Riot’s sole cost and expense.  
4.2.Rejection and Acceptance.  Riot shall have the right to test and inspect the Miners upon delivery and, based thereon, either reject or accept the Miners within [****] ([****]) days after the verified receipt date of the Miners at Riot’s facility (the “Acceptance Period”).  If, during inspection, Riot determines, in its commercially reasonable discretion, that the Miners do not conform to the applicable Purchase Order, Riot shall submit a written notice of rejection to MicroBT within the Acceptance Period.  After receiving the rejection notice, MicroBT shall promptly confirm receipt of the rejection notice and remedy the grounds for rejection, in any event no later than [****] ([****]) days after receipt of Riot’s rejection notice (such remedies may include, but are not limited to, reimbursement of the cost of returning the non-conforming Miners and replacing the non-conforming Miners, or providing a credit against future purchases equal to the amount paid by Riot for such non-conforming Miners).  If Riot does not provide a rejection notice within the Acceptance Period, the Miners delivered shall be deemed accepted.  Riot’s inspection and acceptance rights under this Section 4.2 shall be in addition to, and not in lieu of, any additional rights of Riot with respect to non-conforming Miners.  
4.3.Spare Parts.  As spare parts for the Miners are delivered, MicroBT shall include with each such delivery, free of charge to Riot, extra power supplies and control boards in a quantity equal to one percent (1%) of the power supplies and control boards otherwise delivered with such delivery so that Riot may make self-repairs.  MicroBT hereby authorizes Riot to use the spare parts to repair defective Miners in accordance with the training and guidance to be provided by MicroBT pursuant to Section 5.5.  Such act of self-repair by Riot shall not void its warranty rights in respect of the Miners.
4.4.Late Purchase Order Cancellation.  If MicroBT fails to deliver in full any Batch of Miners within [****] ([****]) days after the applicable Delivery Date, then Riot shall be entitled to cancel the late Batch delivery upon written notice to MicroBT of such cancellation, whereby MicroBT shall, at Riot’s sole discretion, either: (a) refund all amounts paid by Riot under the applicable Purchase Order for such undelivered Miners, including the proportionate Deposit amount, together with interest on all such amounts paid at [****] percent ([****]%) per day for the period from the first day after each payment through the date immediately prior to the Batch’s cancellation date, capped at a maximum of [****] ([****]) days per cancelled Batch (i.e., a maximum accrual of [****] percent ([****]%) interest on all such amounts to be refunded with respect to the applicable cancelled Batch); or (b) provide such amount to Riot as a credit against any future order(s) with MicroBT.
