Pursuant to the Generation Loan Documents, each Payment due under the Generation Loan Documents shall be due and payable on the 25th of each calendar month (each such date a “Payment Date”), as set forth under the heading “Summary of Payment Terms” in each Generation Schedule. The Generation Borrower and Lender Parties desire to amend the Payment Date occurring during the calendar month of December 2022 (the “December Payment Date”) on the terms and conditions set forth herein.

NYDIG hereby agrees that failure to make the scheduled payment of principal and interest with respect to any or all of the Schedules on the December Payment Date shall not constitute a default or Event of Default under the Generation MEFA unless:

(i)all amounts due on the December Payment Date shall not have been paid in full in cash on or prior to January 10, 2023; or

(ii)prior to January 10, 2023, an Event of Default under Section 11(g) of the Generation MEFA shall occur.

Upon the occurrence of the events in either clause (i) or (ii) above, the limited waiver in this Section 1 shall be of no further force and effect, and NYDIG shall be entitled to exercise all rights and remedies in accordance with the terms of the Generation MEFA, including the accruing of default interest pursuant to Section 12(i) of the Generation MEFA from the December Payment Date.

    The parties hereto acknowledge that certain payments of principal and interest owed in respect of the Generation Loan Schedules and the GNY Loan Schedules were, between October 25, 2022 and the date hereof, made using the Restricted Funds (as defined in the Blocked Account Side Letter). NYDIG and the Custodian hereby consent to the use of the Restricted Funds to make such payments.

With effect from the date hereof, the Generation MEFA shall be amended as follows:

(i)Section 12 of the Generation MEFA is hereby amended by adding the following sentence immediately after the first sentence thereof:

“Notwithstanding the foregoing, if an Event of Default pursuant to Section 11(g) occurs, all of the principal amount due and owing under each of the Schedules and all other Obligations of Borrower hereunder and under any other Loan Documents shall automatically and immediately become due and payable, in each case without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower.”

Each Loan Party unconditionally releases, waives and forever discharges on its own behalf and on behalf of each of its subsidiaries and Affiliates (i) any and all liabilities, obligations, duties, promises or indebtedness of any kind of the Lender Parties to the Loan Parties, except the obligations required to be performed by the Lender Parties or agents under the Loan Documents on or after the date hereof and (ii) all claims, offsets, causes of action, suits or defenses of any kind whatsoever (if any), whether arising at law or in equity, whether known or unknown, which a Loan Party might otherwise have against the Lender Parties in connection with this Letter or the other Loan Documents or the transactions contemplated thereby, in the case of each of clauses (i) and (ii), on account of any past or presently existing condition, act, omission, event, contract, liability, obligation, indebtedness, claim, cause of action, defense, circumstance or matter of any kind.

In no event shall the Lender Parties, their affiliates, or any of their respective officers, directors, employees, affiliates, advisors, consultants and agents have any liability for any indirect, consequential or punitive damages in connection with or as a result of such parties’ activities related to this Letter or the Loan Documents.

Each Loan Party agrees on its own behalf and on behalf of its directors, officers, employees, lawyers, advisors and consultants of the Loan Parties and their Affiliates that the

Lender’s execution of this Agreement does not create any such obligation and that each such Person has made its own decisions regarding all of its operations and its incurrence and payment of all third-party debt and all other payments.
