THIS THIRD AMENDMENT dated August 26, 2022 (this “Amendment”), amends that certain Power Purchase Agreement dated June 23, 2021, as amended (the “PPA”), by and among Luminant ET Services Company LLC, a Texas limited liability company (the “Seller”) and Cipher Mining Technologies Inc., a Delaware corporation (the “Buyer”). Capitalized terms not otherwise defined herein shall have the meaning ascribed thereto in the PPA.

WHEREAS, Section 17.10 of the PPA provides that the PPA may be amended only by a writing signed by both parties thereto; and

WHEREAS, the parties hereto desire to amend the PPA in accordance with the terms set forth herein.

AGREEMENT

NOW, THEREFORE, in consideration of the foregoing and for other good and valid consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereby agree as follows:

1.    Amendment. The parties agree to the following:

(a)    Section 1.2 shall be amended by deleting the definition of “Lien Value Credit” and replacing it with the following:

“Lien Value Credit” for each Contract Year shall mean $0.”

(b)    Section 1.2 shall be further amended by adding the following new defined terms thereto in the appropriate alphabetical order:

“Buyer Guarantor” means Cipher Mining Inc., a Delaware corporation.

“Calendar Year” means each successive period of twelve calendar months commencing on January 1 and ending on December 31, except that the first Calendar Year of the Term shall commence on the Effective Date and end on December 31 of the year in which the Effective Date occurs and the last Calendar Year of the Term shall commence on January 1 of the year in which the Term ends and end on the last day of the Term.

“Guaranty” shall mean a guaranty in the form attached hereto as Exhibit B from Buyer’s Guarantor in the amount of $45,000,000.

(c)    Section 4.1 shall be amended by deleting “July 31, 2023” and replacing it with “October 31, 2022.”

As an example, if the first or last Calendar Year is half of a full Calendar Year (i.e., only six months long), Curtailment Events may not exceed 2.5% of the hours in that first or last Calendar Year.”

(e)    Seller agrees to release the 1st Lien on all other property and equipment of Buyer located on the Leased Property or Seller’s Property and, as such, the second paragraph of Section 9.1 shall be amended by deleting it in its entirety and replacing it with the following:

“In addition, the Buyer will give the Seller a 2nd Lien on the Interconnection Electric Facility, junior only to any lien granted to Seller’s Affiliate pursuant to the Purchase Agreement (the “Equipment Collateral”). Within two (2) Business Days of execution of the Third Amendment to the PPA, Buyer shall provide a Guaranty to Seller. Such Guaranty shall be maintained throughout the Term of this PPA.”

(f)    Section 5.1 (C) shall be amended by deleting its text in its entirety and replacing such text with:

GUARANTY

To induce Luminant ET Services Company LLC (“Counterparty”) to extend credit to or for the account of Cipher Mining Technologies Inc. (the “Company”), the undersigned (the “Guarantor”) hereby irrevocably and unconditionally guaranties the punctual payment when due of all obligations (“Obligations”) of the Company to Counterparty now or hereafter existing arising in connection with the Power Purchase Agreement dated June 23, 2021 (the “Agreement”), as limited below. This Guaranty is not intended, nor shall it be construed or deemed, to expand, limit or modify in any respect the Obligations under the Agreement, it being understood and agreed that such Obligations are governed and defined solely by those certain terms and conditions expressly set forth in the Agreement. This is a guaranty of payment and not merely of collection. The Guarantor’s obligation to make a guaranty payment may be satisfied by payment of the required amounts by the Guarantor or by causing the Company to pay such amounts to Counterparty. Upon failure of the Company to perform under the Agreement, Counterparty shall provide the Guarantor with a written demand for payment.

The Guarantor agrees to pay reasonable expenses (including reasonable and documented fees and expenses of counsel) incurred by Counterparty in the enforcement of it rights under this Guaranty.

The liability of the Guarantor under this Guaranty shall be unconditional irrespective of (i) any lack of enforceability of any Obligations, (ii) any change of the time, manner or place of payment, or any other term, of any Obligations, (iii) any law, regulation or order of any jurisdiction affecting any term of any Obligations or Counterparty’s rights with respect thereto, (iv) the insolvency, receivership, reorganization or bankruptcy of the Company or (v) the merger or consolidation of the Company with or into another entity, the loss of the Company’s separate legal identity or the cessation of the Company’s existence. Any other suretyship defenses are hereby waived by the Guarantor.

In addition, notwithstanding anything herein to the contrary, the liability of the Guarantor under this Guaranty, and Counterparty’s right of recovery under this Guaranty, is limited to the aggregate amount of Forty-Five Million U.S. Dollars ($45,000,000). This amount includes any reasonable expenses incurred in connection with enforcement of this Guaranty.

Except as specifically provided for herein, the Guarantor waives promptness, diligence, and notices with respect to any Obligations in this Guaranty and any requirement that Counterparty exhaust any right or take any action against the Company. Except for those defenses expressly waived hereby, the Guarantor reserves for itself all rights, setoffs, counterclaims and other defenses to which the Company is or may be entitled to arising from

or in connection with the Agreement or payment of the Obligations. In the event that any payment of the Company in respect of any Obligations is rescinded or recovered from Counterparty as a preference or fraudulent transfer under the Federal Bankruptcy Code, or any applicable state law, the Guarantor shall remain liable hereunder (and this Guaranty shall be deemed reinstated if necessary) in respect to such Obligations as if such payment had not been made.

This Guaranty shall remain in full force and effect until the earlier to occur of (i) the first date on which both the Agreement is terminated or expired and all Obligations of the Company under the Agreement have been satisfied in full and (ii) the fifth business day after written notice has been received by Counterparty from the Guarantor that it has been revoked. Termination of the Guaranty under clauses (i) or (ii) of the immediately preceding sentence shall not release the Guarantor from any liability as to any Obligations incurred or existing at the time of termination.

The Guarantor shall be subrogated to all of Counterparty’s rights against the Company in respect of any amounts paid by the Guarantor pursuant to the provisions of this Guaranty. Notwithstanding the foregoing, the Guarantor will not exercise any rights which it may acquire by way of subrogation until all the Obligations shall have been performed in full.

No failure or delay on the part of Counterparty to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by Counterparty of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or power. Each and every right, remedy and power hereby granted to Counterparty or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by Counterparty from time to time.

Neither Party may assign its rights, interest or obligations hereunder to any other person without the prior written consent of the other Party and any purported assignment absent such consent is void.

All notices or other communications given or required to be given hereunder shall be in writing at the addresses below either by certified mail with return receipt requested, in person, or by overnight courier service, each of which shall be effective upon receipt.

The Guarantor’s address for notices is as follows:

Counterparty’s address for notices is as follows:

This Guaranty shall be governed by the laws of the State of New York without regard to principles of conflicts of laws. With respect to any suit, action or proceedings relating to this Guaranty (a “Proceeding”), Counterparty, by accepting this Guaranty, and Guarantor each irrevocably (i) submits to the non-exclusive jurisdiction of any federal or state court located in Dallas County in the State of Texas and (ii) waives any objection which it may have at any time to the laying of venue of any Proceeding brought in any such court, waives any claim that such Proceeding has been brought in an inconvenient forum and further waives the right to object, with respect to such Proceeding, that such court does not have jurisdiction over such party.

No amendment, waiver or supplement or other modification of any provision of this Guaranty shall be effective unless the same shall be in writing and signed by Guarantor and Counterparty, and then such amendment, waiver, supplement or other modification shall only be effective in the specific instance and for the specific purpose for which given.
