	  	        A        

  

							
	        	 	where	  	X =	  	the number of Class B Units to be issued to Holder pursuant to this Section 2.4.
				
		 		  	Y =
	  	the number of shares of Class B Units covered by this Warrant in respect of which the net exercise election is made pursuant to this Section 2.4.

exercise election is made in connection with and contingent upon the closing of the sale of units to the public in a public offering pursuant to a Registration Statement under the Act (a “Public Offering”), and if the

 (ii)     If the net exercise election is made in connection
with and contingent upon the closing of any reclassification, reorganization, merger, consolidation or other business combination, sale, dissolution, liquidation or winding-up (each a “Liquidation Event”), then the per unit
value received in such Liquidation Event by the holders of Class B Units. 
 (iii)    If the net exercise election
is not made pursuant to subparagraph (i) or (ii) above, the fair market value shall be determined in good faith by the Company’s board of managers.

warrants, covenants and agrees that: 
 (i)     All Class B Units which may be issued upon the exercise of the
rights represented by this Warrant will, upon issuance, be fully paid and nonassessable and free from all taxes, liens and charges with respect to the issuance thereof (excluding taxes based on the income of the Holder).

times have authorized and reserved for issuance a sufficient number of Warrant Interests as would be required upon the full exercise of the rights represented by this Warrant.

relating to or affecting creditors’ rights and to general equitable principles (whether considered in a proceeding in equity or law).

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.

Company, as if it had been exercised, (ii) the Company will issue Holder an IRS Form k-1 with respect to the equity interest, and (iii) each of the Company and the Holder will not take any actions inconsistent with such treatment, except

to the Company, by certified check or by wire transfer to an account designated by the Company, of an amount equal to the Exercise Price for each Class B Unit being purchased or (ii) by means of a cashless exercise pursuant to
Section 2.4. Until such time as this Warrant is exercised in full or expires, the Exercise Price and the number and type of securities issuable upon exercise of this Warrant are subject to adjustment as set forth in

 2.2    Exercise. Upon surrender of this Warrant
prior to the Expiration Date, with the Form of Warrant Exercise attached hereto as Exhibit A, duly completed, executed and delivered to the Company at its address for notice set forth in Section 15, and upon payment
of the Exercise Price for each Class B Unit purchased, in the manner provided hereunder, evidence representing Holder’s ownership of Class B Units so purchased shall be delivered to the Holder promptly, but in any event within three
(3) Business Days, and, unless this Warrant has been fully exercised or has expired, a new Warrant representing the Class B Units with respect to which this Warrant shall not have been exercised shall also be issued to the Holder within
such time. Such new Warrant shall in all other respects be identical to this Warrant. 
 2.3    Exercise
Price. The Holder may pay the Exercise Price for each Class B Unit to be issued upon exercise of this Warrant (i) by certified check or by wire transfer to an account designated by the Company, or (ii) in accordance

the net exercise election notice attached hereto as Exhibit B duly executed, at the principal office of the Company. Thereupon, the Company shall issue to the Holder such number of fully paid and nonassessable Class B Units as is
computed using the following formula: 
  

					
	                    X        	 	  =      	  	        Y (A – B)        
	  	        A        

  

					
	 where
	  	 X = 
 Y =
	  	 the number of Class B Units to be issued to Holder pursuant to this Section 2.4.

 
 the number of Class B Units covered by this Warrant in respect of which the net
exercise election is made pursuant to this Section 2.4.

			
		  	A =	  	The Fair Market Value (as defined below) of one Class B Unit, as determined at the time the net exercise election is made pursuant to this Section 2.4.
			
		  	B =	  	the Exercise Price in effect under this Warrant at the time the net exercise election is made pursuant to this Section 2.4.

  
 -2- 

 “Fair Market Value” of a Class B Unit, Option or
Convertible Security, as of the relevant date of determination (the “Determination Date”) shall mean: 

(i)    If the net exercise election is made in connection with and contingent upon the closing of the sale of units to the
public in a public offering pursuant to a Registration Statement under the Act (a “Public Offering”), and if the Company’s registration statement relating to such Public Offering (“Registration
Statement”) has been declared effective by the Securities and Exchange Commission, then the initial “Price to Public” specified in the final prospectus with respect to such offering. 

(ii)    If the net exercise election is made in connection with and contingent upon the closing of any reclassification,
reorganization, merger, consolidation or other business combination, sale, dissolution, liquidation or winding-up (each a “Liquidation Event”), then the per unit value received in such
Liquidation Event by the holders of Class B Units. 
 (iii)    If the net exercise election is not made pursuant to
subparagraph (i) or (ii) above, the fair market value shall be determined in good faith by the Company’s board of managers. 

2.5    Representations, Warranties, Covenants and Agreements of the Company. The Company
hereby represents, warrants, covenants and agrees that: 
 (i)    All Class B Units which may be issued upon the

times have authorized and reserved for issuance a sufficient number of Warrant Interests as would be required upon the full exercise of the rights represented by this Warrant.

the jurisdiction of its formation. The Company has full power and authority to execute and deliver this Warrant and to perform its obligations hereunder, and the execution, delivery and performance by the Company of this Warrant have been duly
authorized by all necessary company action. 
 (iv)    This Warrant has been duly and validly executed and delivered by
the Company and constitutes the binding obligations of the Company enforceable against the Company in accordance with its terms, subject to applicable bankruptcy, insolvency or other similar laws relating to or affecting the enforcement of
creditors’ rights generally and to general principles of equity. 
 (v)    The Company shall take all such actions
as may be reasonably necessary or appropriate to ensure that all such Warrant Interests are issued without violation by the Company of any applicable law or governmental regulation and shall pay all its expenses in connection with the issuance or
delivery of the Warrant Interests upon exercise of this Warrant, together with any applicable withholding payable upon the issuance or delivery of the Warrant Interests to the Holder or any other Person; provided, that the Company should not be
required to pay any taxes that may be payable in respect of any transfer involved in respect of the issue of the Warrant or Warrant Interest issuable upon exercise of the Warrant. 

(vi)    Neither the Company nor, to its actual knowledge, any of its Affiliates, officers, directors or beneficial
equityholders of 20% or more of its outstanding securities, has experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Act.

 2.6    Representations, Warranties, Covenants and
Agreements of the Holder. The Holder hereby represents, warrants, covenants and agrees that: 

(i)    The Holder possesses all requisite power and authority necessary to carry out the transactions contemplated by this
Warrant. 
 (ii)    Each of the obligations of the Holder under this Warrant constitutes a valid and binding obligation
of the Holder, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general
equitable principles (whether considered in a proceeding in equity or law). 
 (iii)    The execution and delivery by
the Holder of this Warrant and the fulfillment of and compliance with the terms hereof by the Holder does not and shall not as of the date hereof (i) conflict with or result in a breach by the Holder of the terms, conditions or provisions of,

required after the date hereof under federal or state securities laws. 
 (iv)    The Holder is acquiring the Warrant
Interests and, upon exercise of the Warrant Interests, the Class B Units issuable upon such exercise (collectively, the “Securities”) for its own account, for investment purposes only and not with a view towards, or for
resale in connection with, any public sale or distribution thereof. 
 (v)    The Holder is an “accredited
investor” as such term is defined in Rule 501(a)(3) of Regulation D under the Act, and the Holder has not experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Act. 

(vi)    The Holder understands that the Securities are being offered and will be issued to it in reliance on specific
exemptions from the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and the Holder’s compliance with, the representations and warranties of the
Holder set forth herein in order to determine the availability of such exemptions and the eligibility of the Holder to acquire such Securities. 

(vii)    The Holder did not decide to enter into this Warrant as a result of any general solicitation or general
advertising within the meaning of Rule 502(c) under the Act. 
 (viii)    The Holder has been furnished with all
materials relating to the business, finances and operations of the Company and materials relating to the offer and issuance of the Securities which have been requested by the Holder. The Holder has been afforded the opportunity to ask questions of
the executive officers and directors of the Company. The Holder understands that its investment in the Securities involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an
informed investment decision with respect to the acquisition of the Securities. 
 (ix)    The Holder understands that
no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities by the Holder nor
have such authorities passed upon or endorsed the merits of the offering of the Securities. 

  
 -4- 

 (x)    The Holder understands that: (i) the Securities have not
been and are not being registered under the Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold in reliance on an exemption therefrom,
and (ii) neither the Company nor any other person is under any obligation to register the Securities under the Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder. 

(xi)    The Holder has such knowledge and experience in financial and business matters, knowledge of the high degree of
risk associated with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Securities and is able to bear the economic risk of an investment in
the Securities in the amount contemplated hereunder for an indefinite period of time. The Holder has adequate means of providing for its current financial needs and contingencies and will have no current or anticipated future needs for liquidity
which would be jeopardized by the investment in the Securities. The Holder can afford a complete loss of its investments in the Securities. 

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. 

(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. 

  
 -5- 

 (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 [        ] percent ([    ]%)
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 UNITS. In no event shall
any fractional 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
Class B Unit, then the Class B Units to be issued shall be rounded down to the nearest whole unit, and the Company shall pay to the 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.    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. 

  
 -6- 

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

9.    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.

 10.    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. 

11.    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. 

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

14.    NOTICES. All notices,
requests, consents and other communications hereunder shall be in writing, shall be telecopied or mailed by first class registered or certified airmail (return receipt requested), postage prepaid, and shall be deemed given when so telecopied or, if
mailed, when received:

 15.    WARRANT TAX
TREATMENT. Notwithstanding anything to the contrary contained herein, for U.S. federal income tax purposes, as of the date hereof, (i) this Warrant is treated as an equity interest in the
Company, as if it had been exercised, (ii) the Company will issue Holder an IRS Form K-1 with respect to the equity interest, and (iii) each of the Company and the Holder will not take any actions
inconsistent with such treatment, except as otherwise required by a “determination” within the meaning of Section 1313(a) of the Internal Revenue Code of 1986, as in effect from time to time, and all regulations and guidelines
promulgated thereunder. 
 16.    CONSTRUCTION OF
AGREEMENT. A reference in this Warrant to any Section shall include a reference to every Section the number of which begins with the number of the Section to which reference is specifically made.
The titles and headings herein are for reference purposes only and shall not in any manner limit the construction of this Warrant which shall be considered as a whole. 

17.    NO ENDORSEMENT. The Holder
understands that no federal or state securities administrator has made any finding or determination relating to the fairness of investment in the Company or purchase of the Class B Units hereunder and that no federal or state securities
administrator has recommended or endorsed the offering of Class B Units by the Company hereunder. 

18.    PRONOUNS. All pronouns and any variations thereof
shall be deemed to refer to the masculine, feminine or neuter, singular or plural, as the identity of the person, persons, entity or entities may require. 

19.    FURTHER ASSISTANCE. Each party
agrees to cooperate fully with the other parties and to execute such further instruments, documents and agreements and to give such further written assurances, as may be reasonably requested by any other party to better evidence and reflect the
transactions described herein and contemplated hereby, and to carry into effect the intents and purposes of this Warrant. 

20.    NO IMPAIRMENT. The Company will
not, by amendment of its certificate of formation, limited liability company agreement or other agreement or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary
action, take any action, or fail to take any action, to avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of
all such action as may be necessary or appropriate in order to protect the rights of the Holder against impairment.
