3.     EFFECT OF CERTAIN EVENTS ON WARRANT INTERESTS. The Exercise Price and the number of Class B Units purchasable hereunder are subject to adjustment from time to time as set forth in this Section 3:

(i) Splits. If after the date hereof the Company shall subdivide the Class B Units, by split-up or otherwise, into a greater number of units, then the number of Class B Units issuable on the exercise of this Warrant shall forthwith be proportionately increased, and the Exercise Price shall forthwith be proportionately decreased.

-5-

(ii) Combinations. If after the date hereof the Company shall combine the Class B Units, by combination, reverse split or otherwise, into a smaller number of units, then the number of Class B Units issuable on the exercise of this Warrant shall forthwith be proportionately decreased, and the Exercise Price shall forthwith be proportionately increased.

(iii) Mergers and Reclassifications.     If after the date hereof the Company shall enter into any Reorganization then this Warrant, and all rights to purchase the Warrant Interests issuable upon exercise hereof, shall be deemed exercised immediately prior to the closing of such Reorganization and the Holder shall be entitled to receive the same kind and amount of securities and property receivable upon such Reorganization by any other holder of the number of Class B Units issuable upon exercise of this Warrant. For the purposes of this Section 3, the term “Reorganization” shall include without limitation any reclassification, capital reorganization (other than as a result of a subdivision or stock split provided for in Section 3(i) hereof), or any consolidation of the Company with, or merger of the Company into, another corporation or other business organization (other than a merger in which the Company is the surviving corporation and which does not result in any reclassification or change of the outstanding Class B Units), any sale or conveyance to another corporation or other business organization of all or substantially all of the assets of the Company, or any SPAC Transaction.

(iv) SPAC Transaction. Notwithstanding anything to the contrary in this Warrant, in the event that the Company enters into a Reorganization which constitutes a SPAC Transaction, the number of Class B Units issuable upon exercise of this Warrant in full shall be automatically adjusted such that the number of Class B Units issuable and which shall automatically become exercised in accordance with Section 3(iii) immediately prior to the closing of such SPAC Transaction shall represent a number of Class B Units that when exchanged for the securities and/other property receivable to the members of the Company (including the Holder) equal to ten percent (10%) of all of the issued and outstanding capital stock of the SPAC immediately following the closing of such Reorganization.

4.     MEMBER RIGHTS. The Holder shall not, solely by virtue hereof, be entitled to any rights of a member of the Company. The Holder shall have all rights of a member of the Company with respect to Class B Units purchased upon exercise hereof of the Holder’s rights under this Warrant provided that upon exercise of such rights the Holder executes a joinder agreement to the then-current limited liability company agreement of the Company agreeing to be bound by the terms and conditions thereof. Notwithstanding the foregoing (i) in the event the Company at any time or from time to time on or prior to the Expiration Date shall make or issue, or fix a record date for the determination of holders of Class B Units entitled to receive, a dividend or other distribution payable in cash or other property, then provision shall be made so that the Holder shall receive, at the same time as the holders of the Class B Units, the amount of cash or other such property which the Holder would have been entitled to receive had this Warrant been exercised in full (on a non-cashless basis) for Class B Units on the date of such event, and (ii) nothing shall impose any liabilities on a Holder to purchase any securities or as a member of the Company, whether asserted by the Company or creditors of the Company, prior to the issuance of the underlying Class B Units.

5.    FRACTIONAL SHARES. In no event shall any fractional units of Class B Units be issued upon any exercise of this Warrant. If, upon exercise of this Warrant in its entirety, Holder would, except as provided in this Section 5, be entitled to receive a fractional unit of Class B Units, then the units to be issued

-6-

shall be rounded down to the nearest whole unit, and the Company shall pay to Holder an amount computed by multiplying the fractional interest by the applicable Fair Market Value (as determined in accordance with Section 2 hereof).

6.    TRANSFER.

6.1    Transfer. This warrant may not be assigned to any other party.

6.2     Securities Laws. The Holder, by acceptance hereto agrees that, absent an effective Registration Statement under the Act and qualification under the Act, covering the disposition of Class B Units issued or issuable upon exercise hereof, the Holder will not sell or transfer any or all of such Class B Units, without first providing the Company with an opinion of counsel reasonably acceptable to the Company and its counsel to the effect that such sale or transfer will be exempt from the registration requirements of the Act and the qualification requirements of the Act, and the Holder consents to the Company making a notation on its records in order to implement such restriction on transferability.

7.     CANCELLATION OF PRIOR WARRANT. That certain Warrant to Purchase Class B Units (Class B Warrant No. 2020-01) issued by Griid Infrastructure LLC to Blockchain Access UK Ltd, dated as of July 1, 2020 is hereby terminated with no further force and effect and is superseded in its entirety by this Warrant for Class B Units.

8.     LOSS OR MUTILATION. Upon receipt by the Company of evidence satisfactory to it of the ownership of, and the loss, theft, destruction or mutilation of, this Warrant and (in the case of loss, theft or destruction) of indemnity satisfactory to it, and (in the case of mutilation) upon surrender and cancellation hereof; the Company will execute and deliver in lieu hereof a new Warrant.

9.     NO REDEMPTIONS. The Company shall not have any right to redeem any of the Warrants evidenced hereby.

10.     GOVERNING LAWS. The internal laws of the State of Delaware (irrespective of its choice of law principles) shall govern the validity of this Warrant, the construction of its terms, and the interpretation and enforcement of the rights and duties of the parties hereto.

11.     BINDING UPON SUCCESSORS AND ASSIGNS. Subject to, and unless otherwise provided in, this Warrant, each and all of the covenants, terms, provisions, and agreements contained herein shall be binding upon, and inure to the benefit of the permitted successors, executors, heirs, representatives, administrators and assigns of the parties hereto.

12.    SEVERABILITY. If any provision of this Warrant, or the application hereof, shall for any reason and to any extent, be invalid or unenforceable, the remainder of this Warrant and application of such provisions to other persons or circumstances shall be interpreted so as best to reasonably effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provisions of this Warrant with valid or enforceable provisions which will achieve, to the extent possible, the economic, business and other purposes of the void or unenforceable provisions.

13.    AMENDMENT. This Warrant may be amended upon the written consent of the Company and the Holder.

14.     NO WAIVER. The failure of any party to enforce any of the provisions hereof shall not be construed to be a waiver of the right of such party thereafter to enforce such provisions.
