Hut and US Bitcoin Corp. ("**USBTC**") issued a joint press release with respect to the material change referred to in this report on February 7, 2023, which was disseminated through CISION and filed on SEDAR (<u>www.sedar.com</u>) and EDGAR (<u>www.sec.gov</u>) under Hut's issuer profile.

| **Item 4** | **Summary of Material Change** |

---

On February 6, 2023, Hut, USBTC and a subsidiary of USBTC entered into a definitive business combination agreement (the "**Business Combination Agreement**"), whereby the companies will combine in an all-stock merger of equals to create a preeminent digital asset mining, hosting, managed infrastructure operations, and high performance computing organization. The combined company will be named Hut 8 Corp. ("**New Hut**") and will be a U.S.-domiciled entity. A copy of the Business Combination Agreement has been filed on SEDAR (<u>www.sedar.com</u>) under Hut's profile.

Pursuant to the terms of the Business Combination Agreement, shareholders of Hut will receive, for each Hut share, 0.2000 of a share of New Hut common stock (the "**Hut Consideration**"), which will effectively result in a consolidation of the Hut shares on a 5 to 1 basis. Stockholders of USBTC will receive, for each share of USBTC capital stock, 0.6716 of a share of New Hut common stock (the "**USBTC Consideration**" and together with the Hut Consideration, the "**Consideration**"). Based on the 5-day VWAP for the Hut shares on the Nasdaq Stock Market ("**Nasdaq**") as of the last trading day prior to the date of announcement, the aggregate Consideration implies a combined market capitalization of approximately US$990 million.

The following is a summary of the Business Combination Agreement and is qualified in its entirety by the full text of the Business Combination Agreement.

***The Transaction***

On February 6, 2023, Hut and USBTC entered into the Business Combination Agreement pursuant to which (i) Hut and its direct wholly-owned subsidiary, Hut 8 Holdings Inc., a corporation existing under the laws of British Columbia, will, as part of a court-sanctioned plan of arrangement (the "**Arrangement**") under the *Business Corporations Act* (British Columbia), be amalgamated to continue as one British Columbia corporation ("**Hut Amalco**"), with the capital of Hut Amalco being the same as the capital of Hut (the "**Amalgamation**"), (ii) following the Amalgamation, and pursuant to the Arrangement, each common share of Hut Amalco (other than any shares held by dissenting shareholders) will be exchanged for 0.2000 shares of New Hut common stock, and (iii) following the completion of the Arrangement, a newly-formed direct wholly-owned Nevada subsidiary of New Hut shall merge with and into USBTC, with each share of USBTC common stock being exchanged for 0.6716 (the "**USBTC Exchange Ratio**") of a share of New Hut common stock in a merger executed in accordance with the relevant provisions of the Nevada Revised Statutes, as amended (the "**Merger**," and together with the Arrangement, the "**Transaction**").

The shares of New Hut common stock issued to Hut shareholders under the Arrangement will be issued pursuant to an exemption from registration under Section 3(a)(10) of the U.S. *Securities Act* of 1933. As a result of the Transaction, both Hut Amalco and USBTC will become wholly-owned subsidiaries of New Hut. New Hut intends to list its shares on Nasdaq and the Toronto Stock Exchange (the "**TSX**") under the trading symbol "HUT" following the completion of the Transaction.

The Transaction is expected to close in the second quarter of 2023.

***Approvals***

The Arrangement is subject to, among other things, the approval of the Supreme Court of British Columbia by way of interim and final orders, and the satisfaction or waiver of certain closing conditions customary in transactions of this nature, including the absence of material adverse changes in the business and affairs of Hut.

The Arrangement will require the approval of Hut shareholders at a special meeting expected to take place in the second quarter of 2023 (the "**Hut Meeting**"). In order to become effective, the Arrangement must be approved at the Hut Meeting by at least 66 2/3% of the votes cast by Hut shareholders.

USBTC will seek to obtain at least a majority of the voting power of the outstanding shares of USBTC common stock and preferred stock to adopt and approved the USBTC resolutions approving, among other things, the Merger.

***Board Recommendation***

Stifel GMP and Kroll, LLC have delivered fairness opinions to the effect that, as of February 6, 2023, the USBTC Exchange Ratio is fair, from a financial point of view, to Hut (the "**Fairness Opinions**").

The full text of the Fairness Opinions, which describes, among other things, the assumptions made, procedures followed, factors considered and limitations and qualifications on the review undertaken, along with the terms and conditions of the Business Combination Agreement, will be included in the management information circular of Hut to be prepared in connection with the Hut Meeting.

***Governance and Leadership***

Following the closing of the Transaction, the board of directors of New Hut is expected to consist of 10 directors, comprised of five directors from Hut and five directors from USBTC. The key senior management team and directors will include: Jaime Leverton as Chief Executive Officer, Asher Genoot as President, Michael Ho as Chief Strategy Officer, Bill Tai as Chair of the Board, and Shenif Visram as Chief Financial Officer.

***Support Agreements***

Certain directors and officers of Hut (the "**Hut Supporting Shareholders**") have entered into voting support agreements in connection with the Transaction (the "**Hut Support Agreements**"), pursuant to which, among other things, the Hut Supporting Shareholders have agreed to vote their shares in favour of the Arrangement. Certain directors, officers and other stockholders of USBTC have entered into similar support agreements (the "**USBTC Support Agreements**"), pursuant to which, among other things, such stockholders agree to vote their USBTC stock in favour of the Merger.

***Non-Solicitation and Termination Fee***

The Business Combination Agreement includes non-solicitation provisions for both Hut and USBTC, with Hut maintaining a fiduciary out to accept a superior proposal, subject to USBTC's right to match and other customary exceptions. Hut is required to pay USBTC a termination fee of US$10 million in certain circumstances.

**Cautionary note regarding Forward–Looking Information**

This material change report includes "forward-looking information" and "forward-looking statements" within the meaning of Canadian securities laws and United States securities laws, respectively (collectively, "forward looking information"). All information, other than statements of historical facts, included in this material change report that address activities, events or developments that Hut expects or anticipates will or may occur in the future, including such things as future business strategy, competitive strengths, goals, expansion and growth of Hut's businesses, operations, plans and other such matters is forward-looking information. Forward looking information is often identified by the words "may", "would", "could", "should", "will", "intend", "plan", "anticipate", "allow", "believe", "estimate", "expect", "predict", "can", "might", "potential", "predict", "is designed to", "likely" or similar expressions. In addition, any statements in this material change report that refer to expectations, projections or other characterizations of future events or circumstances contain forward-looking information and include, among others, statements with respect to: (i) the expected outcomes of the Transaction; and (ii) the ability of Hut and USBTC to complete the Transaction on the terms described herein, or at all, including, receipt of required regulatory approvals, shareholder approvals, court approvals, stock exchange approvals and satisfaction of other closing customary conditions, among others.

Statements containing forward-looking information are not historical facts, but instead represent management's expectations, estimates and projections regarding future events based on certain material factors and assumptions at the time the statement was made. While considered reasonable by Hut and USBTC as of the date of material change report, such statements are subject to known and unknown risks, uncertainties, assumptions and other factors that may cause the actual results, level of activity, performance or achievements to be materially different from those expressed or implied by such forward-looking information. For a complete list of the factors that could affect the Company, please see the "Risk Factors" section of Hut's Annual Information Form dated March 17, 2022 and Hut's other continuous disclosure documents which are available on the Hut's profile on the System for Electronic Document Analysis and Retrieval at www.sedar.com and on the EDGAR section of the U.S. Securities and Exchange Commission's ("SEC") website at <u>www.sec.gov</u>. These risks are not intended to represent a complete list of the factors that could affect Hut, USBTC, or New Hut; however, these factors should be considered carefully. There can be no assurance that such estimates and assumptions will prove to be correct. Should one or more of these risks or uncertainties materialize, or should assumptions underlying the forward-looking statements prove incorrect, actual results may vary materially from those described in this material change report as intended, planned, anticipated, believed, sought, proposed, estimated, forecasted, expected, projected or targeted and such forward-looking statements included in this material change report should not be unduly relied upon. The impact of any one assumption, risk, uncertainty, or other factor on a particular forward-looking statement cannot be determined with certainty because they are interdependent and New Hut's future decisions and actions will depend on management's assessment of all information at the relevant time. The forward-looking statements contained in this material change report are made as of the date of this material change report, and each of Hut and USBTC expressly disclaims any obligation to update or alter statements containing any forward-looking information, or the factors or assumptions underlying them, whether as a result of new information, future events or otherwise, except as required by law. Except where otherwise indicated herein, the information provided herein is based on matters as they exist as of the date of preparation and not as of any future date, and will not be updated or otherwise revised to reflect information that subsequently becomes available, or circumstances existing or changes occurring after the date of preparation.

result in any breach of, or be in conflict with, or constitute a default under, or create a state of facts which after notice or lapse
of time or both would constitute a default under: (i) any Contract to which the Securityholder is a party or by which the Securityholder
or any of the property or assets of the Securityholder are bound; (ii) any judgment, decree, order or award of any Governmental Entity;
or (iii) any applicable Laws, except as would not, individually or in the aggregate, reasonably be expected to materially adversely

or by, or filing with, or notification to any Governmental Entity which has not been made or obtained is required to be made or obtained
by the Securityholder in connection with the execution and delivery by the Securityholder and enforcement against the Securityholder of
this Agreement or the performance of the Securityholder's obligations provided for herein other than any filings under insider or
early warning requirements of applicable securities laws (provided that the Securityholder makes no representations or warranties with
respect to the consents, waivers, approvals, authorizations or declarations of or by, or filings with, or notices to any Governmental
Entities or other third parties on the part of Hut or USBTC necessary for the consummation of the transactions contemplated by the Business
Combination Agreement).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) There are no claims, actions, suits, audits, proceedings, investigations or other actions pending against,
or, to the knowledge of the Securityholder, threated against or affecting the Securityholder that, individually or in the aggregate, could
reasonably be expected to have a material and adverse effect on the Securityholder's ability to perform its obligations under this
Agreement.

of the transactions contemplated by the Business Combination Agreement (including the Arrangement) have been duly authorized by all necessary
corporate action on the part of USBTC, and no other corporate proceedings or other actions on the part of the USBTC are necessary to authorize
this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) This Agreement has been duly executed and delivered by USBTC, and, assuming the due execution and delivery
by the Securityholder, constitutes a legal, valid and binding agreement of USBTC enforceable against it in accordance with its terms subject
only to any limitation under bankruptcy, insolvency or other Law affecting the enforcement of creditors' rights generally and the
discretion that a court may exercise in the granting of equitable remedies such as specific performance and injunction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) There are no claims, actions, suits, audits, proceedings, investigations or other actions pending against,
or, to the knowledge of USBTC, threated against or affecting USBTC that, individually or in the aggregate, could reasonably be expected
to have a material and adverse effect on USBTC's ability to perform its obligations under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) No consent, waiver, approval, authorization, order, exemption, registration, licence or declaration of

Agreement.

**ARTICLE 3<br> COVENANTS**

**3.1** **Covenants of the Securityholder** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Securityholder hereby irrevocably and unconditionally covenants with USBTC that, from the date of
this Agreement until the termination of this Agreement in accordance with its terms (the "**Expiry Time** "), the Securityholder
shall not, without having first obtained the prior written consent of USBTC:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) sell, transfer, gift, assign, convey, pledge, hypothecate, encumber, option, grant a security interest
in or otherwise dispose of any right or interest in (including by way of deposit or tender under any take-over bid) any of the Subject
Securities, or enter into any agreement, arrangement or understanding in connection therewith (whether by actual disposition or effective
economic disposition due to cash settlement or otherwise), other than (A) pursuant to the Arrangement, Business Combination Agreement
or an Alternative Transaction, (B) any exercise or settlement, as applicable, of Hut Options, Hut DSUs, or Hut RSUs for Hut Shares
in accordance with their terms including any disposition thereof for tax purposes or for purposes of "sell-to-cover" transactions,
or (C) without affecting beneficial ownership or control or direction over the Subject Securities, to one or more corporations directly
or indirectly wholly owned by the Securityholder or to any member of the Securityholder's immediate family or to a trust, partnership,
limited liability company, or other similar estate planning vehicle for the benefit of the Securityholder or any member of the Securityholder's
immediate family, pursuant to a will, testamentary document or intestate succession upon the death of a Securityholder who is an individual
or pursuant to a family court order (each, a "**Permitted Transfer** "), provided that in each case and for greater certainty,
any Hut Shares acquired as a result thereof shall be Subject Securities and subject to the terms and conditions of this Agreement,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) requisition or join in the requisition of any meeting of any of the Hut Shareholders for the purpose of
considering any resolution, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) other than as set forth herein, grant any proxies or powers of attorney, deposit any Subject Securities
into a voting trust, in any way transfer any of the voting rights associated with any of the Subject Securities, or enter into a voting
agreement, understanding or arrangement with respect to the voting, the right to vote, call meetings of the Hut Shareholders or give consents
or approval of any kind with respect to any Subject Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Securityholder hereby covenants, undertakes and agrees, from the date of this Agreement until the
Expiry Time, to vote (or cause to be voted) all the Subject Securities at any meeting of any of the Hut Shareholders at which the Securityholder
is entitled to vote in respect of such Subject Securities, including without limitation the Hut Meeting, and in any action by written
consent of the Hut Shareholders:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in favour of the approval, consent, ratification and adoption of the Arrangement (including, without limitation,
the Arrangement Resolution) and the transactions contemplated by the Business Combination Agreement (and any actions reasonably required
for the consummation of the transactions contemplated by the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) against (A) any Acquisition Proposal (other than the transactions contemplated by the Business Combination
Agreement); and (B) any action that would reasonably be expected to impede, delay, interfere with, or discourage in any material
respect the transactions contemplated by the Business Combination Agreement and any action that would reasonably be expected to result
in any material breach of any representation, warranty or covenant of Hut in the Business Combination Agreement.

In connection with the foregoing, subject to this Section 3.1(b), the Securityholder hereby irrevocably and unconditionally agrees to deposit an irrevocable proxy or voting instruction form, duly completed and executed in respect of all of the Subject Securities, at least ten Business Days prior to the Hut Meeting, voting all such Subject Securities in favour of the Arrangement Resolution. The Securityholder hereby irrevocably and unconditionally agrees that neither it nor any Person on its behalf will take any action to withdraw, amend or invalidate any proxy or voting instruction form deposited or delivered by the Securityholder pursuant to this Agreement notwithstanding any statutory or other rights which the Securityholder might have unless this Agreement is terminated in accordance with Section 4.1. If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Securityholder hereby covenants, undertakes and agrees to immediately cease and cause to be terminated
any existing solicitation, discussion or negotiation commenced prior to the date of this Agreement with any Person (other than USBTC or
an Affiliate thereof) by such Securityholder or, if applicable, any of its officers, directors, employees, representatives or agents with
respect to any potential Acquisition Proposal (other than the transactions contemplated by the Business Combination Agreement), whether
or not initiated by the Securityholder or any of its officers, directors, employees, representatives or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Subject to the terms and conditions of this Agreement (including, for the avoidance of doubt, Section 4.5)
or except as may be expressly permitted by the Business Combination Agreement or by USBTC in writing, the Securityholder agrees, until
the Expiry Time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) not to exercise any rights of appraisal, Dissent Rights or other rights of dissent that the Securityholder
may have arising from the transactions contemplated by the Business Combination Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) not to bring, or threaten to bring, any suit or proceeding for the purpose of, or which has the effect

thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) not to take any action of any kind, directly or indirectly, which might reasonably be regarded as likely
to reduce the success of, or delay or interfere with, the completion of the transactions contemplated by the Business Combination Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) to cooperate with Hut and USBTC to successfully complete the Arrangement and the other transactions contemplated

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) not to solicit, initiate or otherwise knowingly facilitate any inquiry, proposal or offer that constitutes

Affiliate of USBTC pursuant to the Business Combination Agreement);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) not to participate in any discussions or negotiations with any Person (other than USBTC or an Affiliate
of USBTC) regarding any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an Acquisition
Proposal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) not to accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement,
arrangement or understanding related to any Acquisition Proposal (other than an Acquisition Proposal made by USBTC or an Affiliate of
USBTC pursuant to the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) not to cooperate in any way with, or knowingly assist or participate in, any effort or attempt by any
other Person to do or seek to do any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Securityholder hereby irrevocably consents to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) details of this Agreement being set out in any information circular or U.S. registration statement and
court documents produced by Hut, USBTC or any of their respective Affiliates in connection with the transactions contemplated by this
Agreement and the Business Combination Agreement; and

on the System for Electronic Document Analysis and Retrieval (SEDAR) operated on behalf of the Securities Authority and the Electronic
Data Gathering, Analysis, and Retrieval system (EDGAR).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Except as required by applicable Law, applicable stock exchange requirements or the Business Combination

or pursuant to the Business Combination Agreement without the prior written approval of USBTC.

**3.2** **Covenants of USBTC** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) USBTC hereby agrees and confirms to the Securityholder that it shall take all steps required of it under
the Business Combination Agreement to consummate the transactions contemplated by the Business Combination Agreement (including the Arrangement)
and to cause New Hut to deliver the Hut Consideration Shares to the Depositary, in each case in accordance with and subject to the terms
and conditions of the Business Combination Agreement and the Plan of Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The obligation of USBTC to complete the transactions contemplated by the Business Combination Agreement
(including the Arrangement) shall be subject to the conditions set forth in the Business Combination Agreement.

**3.3** **Co-operation/Alternative Transaction** 

In the event that, in lieu of or in conjunction with the Arrangement, USBTC seeks to complete the transactions contemplated in the Business Combination Agreement other than as contemplated by this Agreement and the Business Combination Agreement on a basis that (a) provides for economic terms which, in relation to the Securityholder, on an after-tax basis, are at least equivalent to or better than those contemplated by this Agreement and the Business Combination Agreement, (b) would not likely result in a delay or time to completion beyond the Outside Date, and (c) is otherwise on terms and conditions not materially more onerous on the Securityholder than the transactions contemplated in the Business Combination (any such transaction, an "**Alternative Transaction**"), then during the term of this Agreement the Securityholder may, on its own accord, and shall, upon written request of USBTC, support the completion of such Alternative Transaction in the same manner as the transactions contemplated in the Business Combination Agreement in accordance with the terms and conditions of this Agreement, including by (A) if applicable, depositing or causing the deposit of its Subject Securities, into an Alternative Transaction conducted by way of a take-over bid made by USBTC or an Affiliate of USBTC and not withdrawing them; and/ or (B) voting or causing to be voted all of the Subject Securities (to the extent that they carry the right to vote) in favour of, and not dissenting from (to the extent dissent rights are available under applicable law), such Alternative Transaction proposed by USBTC and, in the event of any such proposed Alternative Transaction, the references in this Agreement to the "Arrangement" shall be deemed to be changed to "Alternative Transaction" and all terms, covenants, representations and warranties of this Agreement shall be and shall be deemed to have been made in the context of the Alternative Transaction.

**ARTICLE 4<br> GENERAL**

**4.1** **Termination** 

This Agreement shall automatically terminate and be of no further force or effect only upon the earliest of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the written agreement of USBTC and the Securityholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the date and time the Business Combination Agreement is terminated in accordance with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) written notice by the Securityholder to USBTC if, without the prior written consent of the Securityholder,
there is any decrease in the aggregate amount of the Hut Consideration to be received by non-dissenting Hut Shareholders under the terms
of the Arrangement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Effective Time.

Any such termination of this Agreement in accordance with this Section 4.1 shall render the provisions of this Agreement of no further force and effect and no party shall have any further liability or obligations to any other party hereunder, provided however that such termination shall not prejudice the rights of a party as a result of a breach by any other party of its obligations hereunder occurring prior to such termination.

**4.2** **Time of the Essence** 

Time is of the essence in the performance of the parties' respective obligations.

**4.3** **Amendment** 

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

**4.4** **Equitable Relief** 

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, USBTC shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

**4.8** **Notices** 

Any notice, or other communication given regarding the matters contemplated by this Agreement must be in writing, sent by personal delivery, courier, facsimile or electronic mail and addressed:

**4.11** **Fees and Expenses** 

Each party shall pay all fees, costs and expenses incurred by such party in connection with this Agreement.

**4.12** **Independent Legal Advice**

**4.14** **Counterparts** 

This Agreement may be executed in any number of counterparts (including counterparts by facsimile) and all such counterparts taken together shall be deemed to constitute one and the same instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Securityholder hereby irrevocably and unconditionally covenants with USBTC that, from the date of
this Agreement until the termination of this Agreement in accordance with its terms (the "**Expiry Time** "), the Securityholder

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) sell, transfer, gift, assign, convey, pledge, hypothecate, encumber, option, grant a security interest
in or otherwise dispose of any right or interest in (including by way of deposit or tender under any take-over bid) any of the Subject
Securities, or enter into any agreement, arrangement or understanding in connection therewith (whether by actual disposition or effective
economic disposition due to cash settlement or otherwise), other than (A) pursuant to the Arrangement, Business Combination Agreement
or an Alternative Transaction, (B) any exercise or settlement, as applicable, of Hut Options, Hut DSUs, or Hut RSUs for Hut Shares
in accordance with their terms including any disposition thereof for tax purposes or for purposes of "sell-to-cover" transactions,

or indirectly wholly owned by the Securityholder or to any member of the Securityholder's immediate family or to a trust, partnership,
limited liability company, or other similar estate planning vehicle for the benefit of the Securityholder or any member of the Securityholder's
immediate family, pursuant to a will, testamentary document or intestate succession upon the death of a Securityholder who is an individual
or pursuant to a family court order (each, a "**Permitted Transfer** "), provided that in each case and for greater certainty,
any Hut Shares acquired as a result thereof shall be Subject Securities and subject to the terms and conditions of this Agreement,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) requisition or join in the requisition of any meeting of any of the Hut Shareholders for the purpose of
considering any resolution, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) other than as set forth herein, grant any proxies or powers of attorney, deposit any Subject Securities
into a voting trust, in any way transfer any of the voting rights associated with any of the Subject Securities, or enter into a voting
agreement, understanding or arrangement with respect to the voting, the right to vote, call meetings of the Hut Shareholders or give consents
or approval of any kind with respect to any Subject Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Securityholder hereby covenants, undertakes and agrees, from the date of this Agreement until the
Expiry Time, to vote (or cause to be voted) all the Subject Securities at any meeting of any of the Hut Shareholders at which the Securityholder
is entitled to vote in respect of such Subject Securities, including without limitation the Hut Meeting, and in any action by written
consent of the Hut Shareholders:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in favour of the approval, consent, ratification and adoption of the Arrangement (including, without limitation,
the Arrangement Resolution) and the transactions contemplated by the Business Combination Agreement (and any actions reasonably required
for the consummation of the transactions contemplated by the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) against (A) any Acquisition Proposal (other than the transactions contemplated by the Business Combination
Agreement); and (B) any action that would reasonably be expected to impede, delay, interfere with, or discourage in any material
respect the transactions contemplated by the Business Combination Agreement and any action that would reasonably be expected to result
in any material breach of any representation, warranty or covenant of Hut in the Business Combination Agreement.

In connection with the foregoing, subject to this Section 3.1(b), the Securityholder hereby irrevocably and unconditionally agrees to deposit an irrevocable proxy or voting instruction form, duly completed and executed in respect of all of the Subject Securities, at least ten Business Days prior to the Hut Meeting, voting all such Subject Securities in favour of the Arrangement Resolution. The Securityholder hereby irrevocably and unconditionally agrees that neither it nor any Person on its behalf will take any action to withdraw, amend or invalidate any proxy or voting instruction form deposited or delivered by the Securityholder pursuant to this Agreement notwithstanding any statutory or other rights which the Securityholder might have unless this Agreement is terminated in accordance with Section 4.1. If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Securityholder hereby covenants, undertakes and agrees to immediately cease and cause to be terminated
any existing solicitation, discussion or negotiation commenced prior to the date of this Agreement with any Person (other than USBTC or
an Affiliate thereof) by such Securityholder or, if applicable, any of its officers, directors, employees, representatives or agents with
respect to any potential Acquisition Proposal (other than the transactions contemplated by the Business Combination Agreement), whether
or not initiated by the Securityholder or any of its officers, directors, employees, representatives or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Subject to the terms and conditions of this Agreement (including, for the avoidance of doubt, Section 4.5)
or except as may be expressly permitted by the Business Combination Agreement or by USBTC in writing, the Securityholder agrees, until
the Expiry Time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) not to exercise any rights of appraisal, Dissent Rights or other rights of dissent that the Securityholder
may have arising from the transactions contemplated by the Business Combination Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) not to bring, or threaten to bring, any suit or proceeding for the purpose of, or which has the effect
of, directly or indirectly, stopping, preventing, impeding, delaying or varying in any material respect such transactions or any aspect
thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) not to take any action of any kind, directly or indirectly, which might reasonably be regarded as likely
to reduce the success of, or delay or interfere with, the completion of the transactions contemplated by the Business Combination Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) to cooperate with Hut and USBTC to successfully complete the Arrangement and the other transactions contemplated
by the Business Combination Agreement and this Agreement, and to oppose any of the matters in Section 3.1(b)(ii);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) not to solicit, initiate or otherwise knowingly facilitate any inquiry, proposal or offer that constitutes
or may reasonably be expected to constitute or lead to, an Acquisition Proposal (other than an Acquisition Proposal made by USBTC or an
Affiliate of USBTC pursuant to the Business Combination Agreement);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) not to participate in any discussions or negotiations with any Person (other than USBTC or an Affiliate
of USBTC) regarding any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an Acquisition
Proposal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) not to accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement,
arrangement or understanding related to any Acquisition Proposal (other than an Acquisition Proposal made by USBTC or an Affiliate of
USBTC pursuant to the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) not to cooperate in any way with, or knowingly assist or participate in, any effort or attempt by any
other Person to do or seek to do any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Securityholder hereby irrevocably consents to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) details of this Agreement being set out in any information circular or U.S. registration statement and
court documents produced by Hut, USBTC or any of their respective Affiliates in connection with the transactions contemplated by this
Agreement and the Business Combination Agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) this Agreement or details of this Agreement otherwise being made publicly available, including by filing

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Except as required by applicable Law, applicable stock exchange requirements or the Business Combination

or pursuant to the Business Combination Agreement without the prior written approval of USBTC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) USBTC hereby agrees and confirms to the Securityholder that it shall take all steps required of it under
the Business Combination Agreement to consummate the transactions contemplated by the Business Combination Agreement (including the Arrangement)
and to cause New Hut to deliver the Hut Consideration Shares to the Depositary, in each case in accordance with and subject to the terms
and conditions of the Business Combination Agreement and the Plan of Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The obligation of USBTC to complete the transactions contemplated by the Business Combination Agreement
(including the Arrangement) shall be subject to the conditions set forth in the Business Combination Agreement.

**3.3** **Co-operation/Alternative Transaction** 

In the event that, in lieu of or in conjunction with the Arrangement, USBTC seeks to complete the transactions contemplated in the Business Combination Agreement other than as contemplated by this Agreement and the Business Combination Agreement on a basis that (a) provides for economic terms which, in relation to the Securityholder, on an after-tax basis, are at least equivalent to or better than those contemplated by this Agreement and the Business Combination Agreement, (b) would not likely result in a delay or time to completion beyond the Outside Date, and (c) is otherwise on terms and conditions not materially more onerous on the Securityholder than the transactions contemplated in the Business Combination (any such transaction, an "**Alternative Transaction**"), then during the term of this Agreement the Securityholder may, on its own accord, and shall, upon written request of USBTC, support the completion of such Alternative Transaction in the same manner as the transactions contemplated in the Business Combination Agreement in accordance with the terms and conditions of this Agreement, including by (A) if applicable, depositing or causing the deposit of its Subject Securities, into an Alternative Transaction conducted by way of a take-over bid made by USBTC or an Affiliate of USBTC and not withdrawing them; and/ or (B) voting or causing to be voted all of the Subject Securities (to the extent that they carry the right to vote) in favour of, and not dissenting from (to the extent dissent rights are available under applicable law), such Alternative Transaction proposed by USBTC and, in the event of any such proposed Alternative Transaction, the references in this Agreement to the "Arrangement" shall be deemed to be changed to "Alternative Transaction" and all terms, covenants, representations and warranties of this Agreement shall be and shall be deemed to have been made in the context of the Alternative Transaction.

**ARTICLE 4<br> GENERAL**

**4.1** **Termination** 

This Agreement shall automatically terminate and be of no further force or effect only upon the earliest of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the written agreement of USBTC and the Securityholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the date and time the Business Combination Agreement is terminated in accordance with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) written notice by the Securityholder to USBTC if, without the prior written consent of the Securityholder,
there is any decrease in the aggregate amount of the Hut Consideration to be received by non-dissenting Hut Shareholders under the terms
of the Arrangement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Effective Time.

Any such termination of this Agreement in accordance with this Section 4.1 shall render the provisions of this Agreement of no further force and effect and no party shall have any further liability or obligations to any other party hereunder, provided however that such termination shall not prejudice the rights of a party as a result of a breach by any other party of its obligations hereunder occurring prior to such termination.

**4.2** **Time of the Essence** 

Time is of the essence in the performance of the parties' respective obligations.

**4.3** **Amendment** 

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

**4.4** **Equitable Relief** 

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, USBTC shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

**4.8** **Notices** 

Any notice, or other communication given regarding the matters contemplated by this Agreement must be in writing, sent by personal delivery, courier, facsimile or electronic mail and addressed:

Sending a copy of a notice or other communication to a party's legal counsel as contemplated above is for information purposes only and does not constitute delivery of the notice or other communication to that party. The failure to send a copy of a notice or other communication to legal counsel does not invalidate delivery of that notice or other communication to a party.

**4.9** **Severability** 

If any provision of this Agreement is determined to be illegal, invalid or unenforceable by any court of competent jurisdiction, that provision will be severed from this Agreement and the remaining provisions shall remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

**4.10** **Successors and Assigns** 

The provisions of this Agreement shall be binding upon and enure to the benefit of the parties hereto and their respective successors, permitted assigns and legal personal representatives, provided that, except as permitted by Section 3.1(a)(i) in connection with a Permitted Transfer (provided that the Securityholder shall continue to be liable jointly and severally with the transferee(s) to such Permitted Transfer), no party may assign, delegate or otherwise transfer any of its rights, interests or obligations under this Agreement without the prior written consent of the other parties hereto, provided that USBTC may assign all or part of its right under this Agreement to, and its obligations under this Agreement may be assumed by, any of its Affiliates, provided that if such agreement and/or assumption takes place, USBTC shall continue to be liable jointly and severally with such Affiliate, as the case may be, for all of its obligations hereunder, without the consent of the Securityholder.

**4.11** **Fees and Expenses** 

Each party shall pay all fees, costs and expenses incurred by such party in connection with this Agreement.

**4.12** **Independent Legal Advice** 

The Securityholder acknowledges that it has been afforded the opportunity to obtain independent legal advice and confirms by the execution of this Agreement that it has either done so or waived its right to do so in connection with the entering into of this Agreement.

**4.13** **Further Assurances** 

Each of the parties will, from time to time, execute and deliver all such further documents and instruments and do all such acts and things as the other party may reasonably require and at the requesting party's cost (it being agreed that the requesting party will only be responsible for the reasonable, out-of-pocket costs incurred by the incurring party) to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement.

**4.14** **Counterparts** 

This Agreement may be executed in any number of counterparts (including counterparts by facsimile) and all such counterparts taken together shall be deemed to constitute one and the same instrument. The parties shall be entitled to rely upon delivery of an executed facsimile or similar executed electronic copy of this Agreement, and such facsimile or similar executed electronic copy shall be legally effective to create a valid and binding agreement between the parties.

agreement, understanding or arrangement with respect to the voting, the right to vote, call meetings of the Hut Shareholders or give consents
or approval of any kind with respect to any Subject Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Securityholder hereby covenants, undertakes and agrees, from the date of this Agreement until the
Expiry Time, to vote (or cause to be voted) all the Subject Securities at any meeting of any of the Hut Shareholders at which the Securityholder

consent of the Hut Shareholders:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in favour of the approval, consent, ratification and adoption of the Arrangement (including, without limitation,
the Arrangement Resolution) and the transactions contemplated by the Business Combination Agreement (and any actions reasonably required
for the consummation of the transactions contemplated by the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) against (A) any Acquisition Proposal (other than the transactions contemplated by the Business Combination

If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Securityholder hereby covenants, undertakes and agrees to immediately cease and cause to be terminated
any existing solicitation, discussion or negotiation commenced prior to the date of this Agreement with any Person (other than USBTC or
an Affiliate thereof) by such Securityholder or, if applicable, any of its officers, directors, employees, representatives or agents with
respect to any potential Acquisition Proposal (other than the transactions contemplated by the Business Combination Agreement), whether
or not initiated by the Securityholder or any of its officers, directors, employees, representatives or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Subject to the terms and conditions of this Agreement (including, for the avoidance of doubt, Section 4.5)

the Expiry Time:

may have arising from the transactions contemplated by the Business Combination Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) not to bring, or threaten to bring, any suit or proceeding for the purpose of, or which has the effect

**3.3** **Co-operation/Alternative Transaction** 

In the event that, in lieu of or in conjunction with the Arrangement, USBTC seeks to complete the transactions contemplated in the Business Combination Agreement other than as contemplated by this Agreement and the Business Combination Agreement on a basis that (a) provides for economic terms which, in relation to the Securityholder, on an after-tax basis, are at least equivalent to or better than those contemplated by this Agreement and the Business Combination Agreement, (b) would not likely result in a delay or time to completion beyond the Outside Date, and (c) is otherwise on terms and conditions not materially more onerous on the Securityholder than the transactions contemplated in the Business Combination (any such transaction, an "**Alternative Transaction**"), then during the term of this Agreement the Securityholder may, on its own accord, and shall, upon written request of USBTC, support the completion of such Alternative Transaction in the same manner as the transactions contemplated in the Business Combination Agreement in accordance with the terms and conditions of this Agreement, including by (A) if applicable, depositing or causing the deposit of its Subject Securities, into an Alternative Transaction conducted by way of a take-over bid made by USBTC or an Affiliate of USBTC and not withdrawing them; and/ or (B) voting or causing to be voted all of the Subject Securities (to the extent that they carry the right to vote) in favour of, and not dissenting from (to the extent dissent rights are available under applicable law), such Alternative Transaction proposed by USBTC and, in the event of any such proposed Alternative Transaction, the references in this Agreement to the "Arrangement" shall be deemed to be changed to "Alternative Transaction" and all terms, covenants, representations and warranties of this Agreement shall be and shall be deemed to have been made in the context of the Alternative Transaction.

**ARTICLE 4<br> GENERAL**

**4.1** **Termination** 

This Agreement shall automatically terminate and be of no further force or effect only upon the earliest of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the written agreement of USBTC and the Securityholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the date and time the Business Combination Agreement is terminated in accordance with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) written notice by the Securityholder to USBTC if, without the prior written consent of the Securityholder,
there is any decrease in the aggregate amount of the Hut Consideration to be received by non-dissenting Hut Shareholders under the terms
of the Arrangement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Effective Time.

Any such termination of this Agreement in accordance with this Section 4.1 shall render the provisions of this Agreement of no further force and effect and no party shall have any further liability or obligations to any other party hereunder, provided however that such termination shall not prejudice the rights of a party as a result of a breach by any other party of its obligations hereunder occurring prior to such termination.

**4.2** **Time of the Essence** 

Time is of the essence in the performance of the parties' respective obligations.

**4.3** **Amendment** 

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

**4.4** **Equitable Relief** 

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, USBTC shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

**4.8** **Notices** 

Any notice, or other communication given regarding the matters contemplated by this Agreement must be in writing, sent by personal delivery, courier, facsimile or electronic mail and addressed:

The failure to send a copy of a notice or other communication to legal counsel does not invalidate delivery of that notice or other communication to a party.

**4.9** **Severability** 

If any provision of this Agreement is determined to be illegal, invalid or unenforceable by any court of competent jurisdiction, that provision will be severed from this Agreement and the remaining provisions shall remain in full force and effect.

or approval of any kind with respect to any Subject Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Securityholder hereby covenants, undertakes and agrees, from the date of this Agreement until the

consent of the Hut Shareholders:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in favour of the approval, consent, ratification and adoption of the Arrangement (including, without limitation,

If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Securityholder hereby covenants, undertakes and agrees to immediately cease and cause to be terminated

respect to any potential Acquisition Proposal (other than the transactions contemplated by the Business Combination Agreement), whether
or not initiated by the Securityholder or any of its officers, directors, employees, representatives or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Subject to the terms and conditions of this Agreement (including, for the avoidance of doubt, Section 4.5)

The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

contemplated hereby or the compliance by the Securityholder with the Securityholder's obligations hereunder will violate, contravene,
result in any breach of, or be in conflict with, or constitute a default under, or create a state of facts which after notice or lapse

or any of the property or assets of the Securityholder are bound; (ii) any judgment, decree, order or award of any Governmental Entity;
or (iii) any applicable Laws, except as would not, individually or in the aggregate, reasonably be expected to materially adversely

in or otherwise dispose of any right or interest in (including by way of deposit or tender under any take-over bid) any of the Subject

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) requisition or join in the requisition of any meeting of any of the Hut Shareholders for the purpose of

into a voting trust, in any way transfer any of the voting rights associated with any of the Subject Securities, or enter into a voting
agreement, understanding or arrangement with respect to the voting, the right to vote, call meetings of the Hut Shareholders or give consents
or approval of any kind with respect to any Subject Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Securityholder hereby covenants, undertakes and agrees, from the date of this Agreement until the
Expiry Time, to vote (or cause to be voted) all the Subject Securities at any meeting of any of the Hut Shareholders at which the Securityholder
is entitled to vote in respect of such Subject Securities, including without limitation the Hut Meeting, and in any action by written
consent of the Hut Shareholders:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in favour of the approval, consent, ratification and adoption of the Arrangement (including, without limitation,

The Securityholder hereby irrevocably and unconditionally agrees that neither it nor any Person on its behalf will take any action to withdraw, amend or invalidate any proxy or voting instruction form deposited or delivered by the Securityholder pursuant to this Agreement notwithstanding any statutory or other rights which the Securityholder might have unless this Agreement is terminated in accordance with Section 4.1. If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Securityholder hereby covenants, undertakes and agrees to immediately cease and cause to be terminated
any existing solicitation, discussion or negotiation commenced prior to the date of this Agreement with any Person (other than USBTC or
an Affiliate thereof) by such Securityholder or, if applicable, any of its officers, directors, employees, representatives or agents with
respect to any potential Acquisition Proposal (other than the transactions contemplated by the Business Combination Agreement), whether
or not initiated by the Securityholder or any of its officers, directors, employees, representatives or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Subject to the terms and conditions of this Agreement (including, for the avoidance of doubt, Section 4.5)
or except as may be expressly permitted by the Business Combination Agreement or by USBTC in writing, the Securityholder agrees, until
the Expiry Time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) not to exercise any rights of appraisal, Dissent Rights or other rights of dissent that the Securityholder
may have arising from the transactions contemplated by the Business Combination Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) not to bring, or threaten to bring, any suit or proceeding for the purpose of, or which has the effect

Affiliate of USBTC pursuant to the Business Combination Agreement);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) not to participate in any discussions or negotiations with any Person (other than USBTC or an Affiliate

the Business Combination Agreement to consummate the transactions contemplated by the Business Combination Agreement (including the Arrangement)
and to cause New Hut to deliver the Hut Consideration Shares to the Depositary, in each case in accordance with and subject to the terms
and conditions of the Business Combination Agreement and the Plan of Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The obligation of USBTC to complete the transactions contemplated by the Business Combination Agreement
(including the Arrangement) shall be subject to the conditions set forth in the Business Combination Agreement.

**3.3** **Co-operation/Alternative Transaction** 

In the event that, in lieu of or in conjunction with the Arrangement, USBTC seeks to complete the transactions contemplated in the Business Combination Agreement other than as contemplated by this Agreement and the Business Combination Agreement on a basis that (a) provides for economic terms which, in relation to the Securityholder, on an after-tax basis, are at least equivalent to or better than those contemplated by this Agreement and the Business Combination Agreement, (b) would not likely result in a delay or time to completion beyond the Outside Date, and (c) is otherwise on terms and conditions not materially more onerous on the Securityholder than the transactions contemplated in the Business Combination (any such transaction, an "**Alternative Transaction**"), then during the term of this Agreement the Securityholder may, on its own accord, and shall, upon written request of USBTC, support the completion of such Alternative Transaction in the same manner as the transactions contemplated in the Business Combination Agreement in accordance with the terms and conditions of this Agreement, including by (A) if applicable, depositing or causing the deposit of its Subject Securities, into an Alternative Transaction conducted by way of a take-over bid made by USBTC or an Affiliate of USBTC and not withdrawing them; and/ or (B) voting or causing to be voted all of the Subject Securities (to the extent that they carry the right to vote) in favour of, and not dissenting from (to the extent dissent rights are available under applicable law), such Alternative Transaction proposed by USBTC and, in the event of any such proposed Alternative Transaction, the references in this Agreement to the "Arrangement" shall be deemed to be changed to "Alternative Transaction" and all terms, covenants, representations and warranties of this Agreement shall be and shall be deemed to have been made in the context of the Alternative Transaction.

**ARTICLE 4<br> GENERAL**

**4.1** **Termination** 

This Agreement shall automatically terminate and be of no further force or effect only upon the earliest of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the written agreement of USBTC and the Securityholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the date and time the Business Combination Agreement is terminated in accordance with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) written notice by the Securityholder to USBTC if, without the prior written consent of the Securityholder,
there is any decrease in the aggregate amount of the Hut Consideration to be received by non-dissenting Hut Shareholders under the terms
of the Arrangement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Effective Time.

Any such termination of this Agreement in accordance with this Section 4.1 shall render the provisions of this Agreement of no further force and effect and no party shall have any further liability or obligations to any other party hereunder, provided however that such termination shall not prejudice the rights of a party as a result of a breach by any other party of its obligations hereunder occurring prior to such termination.

**4.2** **Time of the Essence** 

Time is of the essence in the performance of the parties' respective obligations.

**4.3** **Amendment** 

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

**4.4** **Equitable Relief** 

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, USBTC shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

**4.8** **Notices**

**4.11** **Fees and Expenses** 

Each party shall pay all fees, costs and expenses incurred by such party in connection with this Agreement.

**4.12** **Independent Legal Advice**

**4.13** **Further Assurances** 

Each of the parties will, from time to time, execute and deliver all such further documents and instruments and do all such acts and things as the other party may reasonably require and at the requesting party's cost (it being agreed that the requesting party will only be responsible for the reasonable, out-of-pocket costs incurred by the incurring party) to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement.

**4.14** **Counterparts** 

This Agreement may be executed in any number of counterparts (including counterparts by facsimile) and all such counterparts taken together shall be deemed to constitute one and the same instrument.

In connection with the foregoing, subject to this Section 3.1(b), the Securityholder hereby irrevocably and unconditionally agrees to deposit an irrevocable proxy or voting instruction form, duly completed and executed in respect of all of the Subject Securities, at least ten Business Days prior to the Hut Meeting, voting all such Subject Securities in favour of the Arrangement Resolution.

If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) not to bring, or threaten to bring, any suit or proceeding for the purpose of, or which has the effect

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) not to take any action of any kind, directly or indirectly, which might reasonably be regarded as likely

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) to cooperate with Hut and USBTC to successfully complete the Arrangement and the other transactions contemplated

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) not to solicit, initiate or otherwise knowingly facilitate any inquiry, proposal or offer that constitutes

Affiliate of USBTC pursuant to the Business Combination Agreement);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) not to participate in any discussions or negotiations with any Person (other than USBTC or an Affiliate
of USBTC) regarding any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an Acquisition
Proposal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) not to accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement,
arrangement or understanding related to any Acquisition Proposal (other than an Acquisition Proposal made by USBTC or an Affiliate of
USBTC pursuant to the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) not to cooperate in any way with, or knowingly assist or participate in, any effort or attempt by any
other Person to do or seek to do any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) USBTC hereby agrees and confirms to the Securityholder that it shall take all steps required of it under
the Business Combination Agreement to consummate the transactions contemplated by the Business Combination Agreement (including the Arrangement)
and to cause New Hut to deliver the Hut Consideration Shares to the Depositary, in each case in accordance with and subject to the terms
and conditions of the Business Combination Agreement and the Plan of Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The obligation of USBTC to complete the transactions contemplated by the Business Combination Agreement
(including the Arrangement) shall be subject to the conditions set forth in the Business Combination Agreement.

**3.3** **Co-operation/Alternative Transaction** 

In the event that, in lieu of or in conjunction with the Arrangement, USBTC seeks to complete the transactions contemplated in the Business Combination Agreement other than as contemplated by this Agreement and the Business Combination Agreement on a basis that (a) provides for economic terms which, in relation to the Securityholder, on an after-tax basis, are at least equivalent to or better than those contemplated by this Agreement and the Business Combination Agreement, (b) would not likely result in a delay or time to completion beyond the Outside Date, and (c) is otherwise on terms and conditions not materially more onerous on the Securityholder than the transactions contemplated in the Business Combination (any such transaction, an "**Alternative Transaction**"), then during the term of this Agreement the Securityholder may, on its own accord, and shall, upon written request of USBTC, support the completion of such Alternative Transaction in the same manner as the transactions contemplated in the Business Combination Agreement in accordance with the terms and conditions of this Agreement, including by (A) if applicable, depositing or causing the deposit of its Subject Securities, into an Alternative Transaction conducted by way of a take-over bid made by USBTC or an Affiliate of USBTC and not withdrawing them; and/ or (B) voting or causing to be voted all of the Subject Securities (to the extent that they carry the right to vote) in favour of, and not dissenting from (to the extent dissent rights are available under applicable law), such Alternative Transaction proposed by USBTC and, in the event of any such proposed Alternative Transaction, the references in this Agreement to the "Arrangement" shall be deemed to be changed to "Alternative Transaction" and all terms, covenants, representations and warranties of this Agreement shall be and shall be deemed to have been made in the context of the Alternative Transaction.

**ARTICLE 4<br> GENERAL**

**4.1** **Termination** 

This Agreement shall automatically terminate and be of no further force or effect only upon the earliest of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the written agreement of USBTC and the Securityholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the date and time the Business Combination Agreement is terminated in accordance with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) written notice by the Securityholder to USBTC if, without the prior written consent of the Securityholder,
there is any decrease in the aggregate amount of the Hut Consideration to be received by non-dissenting Hut Shareholders under the terms
of the Arrangement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Effective Time.

Any such termination of this Agreement in accordance with this Section 4.1 shall render the provisions of this Agreement of no further force and effect and no party shall have any further liability or obligations to any other party hereunder, provided however that such termination shall not prejudice the rights of a party as a result of a breach by any other party of its obligations hereunder occurring prior to such termination.

**4.2** **Time of the Essence** 

Time is of the essence in the performance of the parties' respective obligations.

**4.3** **Amendment** 

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

**4.4** **Equitable Relief** 

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, USBTC shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

**4.8** **Notices**

**4.11** **Fees and Expenses** 

Each party shall pay all fees, costs and expenses incurred by such party in connection with this Agreement.

**4.12** **Independent Legal Advice**

Each of the parties will, from time to time, execute and deliver all such further documents and instruments and do all such acts and things as the other party may reasonably require and at the requesting party's cost (it being agreed that the requesting party will only be responsible for the reasonable, out-of-pocket costs incurred by the incurring party) to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement.

**4.14** **Counterparts** 

This Agreement may be executed in any number of counterparts (including counterparts by facsimile) and all such counterparts taken together shall be deemed to constitute one and the same instrument.

**3.1** **Covenants of the Securityholder** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Securityholder hereby irrevocably and unconditionally covenants with USBTC that, from the date of
this Agreement until the termination of this Agreement in accordance with its terms (the "**Expiry Time** "), the Securityholder
shall not, without having first obtained the prior written consent of USBTC:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) sell, transfer, gift, assign, convey, pledge, hypothecate, encumber, option, grant a security interest
in or otherwise dispose of any right or interest in (including by way of deposit or tender under any take-over bid) any of the Subject
Securities, or enter into any agreement, arrangement or understanding in connection therewith (whether by actual disposition or effective
economic disposition due to cash settlement or otherwise), other than (A) pursuant to the Arrangement, Business Combination Agreement
or an Alternative Transaction, (B) any exercise or settlement, as applicable, of Hut Options, Hut DSUs, or Hut RSUs for Hut Shares
in accordance with their terms including any disposition thereof for tax purposes or for purposes of "sell-to-cover" transactions,
or (C) without affecting beneficial ownership or control or direction over the Subject Securities, to one or more corporations directly
or indirectly wholly owned by the Securityholder or to any member of the Securityholder's immediate family or to a trust, partnership,
limited liability company, or other similar estate planning vehicle for the benefit of the Securityholder or any member of the Securityholder's
immediate family, pursuant to a will, testamentary document or intestate succession upon the death of a Securityholder who is an individual
or pursuant to a family court order (each, a "**Permitted Transfer** "), provided that in each case and for greater certainty,
any Hut Shares acquired as a result thereof shall be Subject Securities and subject to the terms and conditions of this Agreement,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) requisition or join in the requisition of any meeting of any of the Hut Shareholders for the purpose of
considering any resolution, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) other than as set forth herein, grant any proxies or powers of attorney, deposit any Subject Securities
into a voting trust, in any way transfer any of the voting rights associated with any of the Subject Securities, or enter into a voting
agreement, understanding or arrangement with respect to the voting, the right to vote, call meetings of the Hut Shareholders or give consents
or approval of any kind with respect to any Subject Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Securityholder hereby covenants, undertakes and agrees, from the date of this Agreement until the
Expiry Time, to vote (or cause to be voted) all the Subject Securities at any meeting of any of the Hut Shareholders at which the Securityholder
is entitled to vote in respect of such Subject Securities, including without limitation the Hut Meeting, and in any action by written
consent of the Hut Shareholders:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in favour of the approval, consent, ratification and adoption of the Arrangement (including, without limitation,
the Arrangement Resolution) and the transactions contemplated by the Business Combination Agreement (and any actions reasonably required
for the consummation of the transactions contemplated by the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) against (A) any Acquisition Proposal (other than the transactions contemplated by the Business Combination
Agreement); and (B) any action that would reasonably be expected to impede, delay, interfere with, or discourage in any material
respect the transactions contemplated by the Business Combination Agreement and any action that would reasonably be expected to result
in any material breach of any representation, warranty or covenant of Hut in the Business Combination Agreement.

In connection with the foregoing, subject to this Section 3.1(b), the Securityholder hereby irrevocably and unconditionally agrees to deposit an irrevocable proxy or voting instruction form, duly completed and executed in respect of all of the Subject Securities, at least ten Business Days prior to the Hut Meeting, voting all such Subject Securities in favour of the Arrangement Resolution. The Securityholder hereby irrevocably and unconditionally agrees that neither it nor any Person on its behalf will take any action to withdraw, amend or invalidate any proxy or voting instruction form deposited or delivered by the Securityholder pursuant to this Agreement notwithstanding any statutory or other rights which the Securityholder might have unless this Agreement is terminated in accordance with Section 4.1. If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Securityholder hereby covenants, undertakes and agrees to immediately cease and cause to be terminated
any existing solicitation, discussion or negotiation commenced prior to the date of this Agreement with any Person (other than USBTC or
an Affiliate thereof) by such Securityholder or, if applicable, any of its officers, directors, employees, representatives or agents with
respect to any potential Acquisition Proposal (other than the transactions contemplated by the Business Combination Agreement), whether
or not initiated by the Securityholder or any of its officers, directors, employees, representatives or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Subject to the terms and conditions of this Agreement (including, for the avoidance of doubt, Section 4.5)
or except as may be expressly permitted by the Business Combination Agreement or by USBTC in writing, the Securityholder agrees, until
the Expiry Time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) not to exercise any rights of appraisal, Dissent Rights or other rights of dissent that the Securityholder
may have arising from the transactions contemplated by the Business Combination Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) not to bring, or threaten to bring, any suit or proceeding for the purpose of, or which has the effect
of, directly or indirectly, stopping, preventing, impeding, delaying or varying in any material respect such transactions or any aspect
thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) not to take any action of any kind, directly or indirectly, which might reasonably be regarded as likely
to reduce the success of, or delay or interfere with, the completion of the transactions contemplated by the Business Combination Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) to cooperate with Hut and USBTC to successfully complete the Arrangement and the other transactions contemplated
by the Business Combination Agreement and this Agreement, and to oppose any of the matters in Section 3.1(b)(ii);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) not to solicit, initiate or otherwise knowingly facilitate any inquiry, proposal or offer that constitutes

Affiliate of USBTC pursuant to the Business Combination Agreement);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) not to participate in any discussions or negotiations with any Person (other than USBTC or an Affiliate
of USBTC) regarding any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an Acquisition
Proposal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) not to accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement,
arrangement or understanding related to any Acquisition Proposal (other than an Acquisition Proposal made by USBTC or an Affiliate of
USBTC pursuant to the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) not to cooperate in any way with, or knowingly assist or participate in, any effort or attempt by any
other Person to do or seek to do any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Securityholder hereby irrevocably consents to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) details of this Agreement being set out in any information circular or U.S. registration statement and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) USBTC hereby agrees and confirms to the Securityholder that it shall take all steps required of it under
the Business Combination Agreement to consummate the transactions contemplated by the Business Combination Agreement (including the Arrangement)
and to cause New Hut to deliver the Hut Consideration Shares to the Depositary, in each case in accordance with and subject to the terms
and conditions of the Business Combination Agreement and the Plan of Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The obligation of USBTC to complete the transactions contemplated by the Business Combination Agreement
(including the Arrangement) shall be subject to the conditions set forth in the Business Combination Agreement.

**3.3** **Co-operation/Alternative Transaction** 

In the event that, in lieu of or in conjunction with the Arrangement, USBTC seeks to complete the transactions contemplated in the Business Combination Agreement other than as contemplated by this Agreement and the Business Combination Agreement on a basis that (a) provides for economic terms which, in relation to the Securityholder, on an after-tax basis, are at least equivalent to or better than those contemplated by this Agreement and the Business Combination Agreement, (b) would not likely result in a delay or time to completion beyond the Outside Date, and (c) is otherwise on terms and conditions not materially more onerous on the Securityholder than the transactions contemplated in the Business Combination (any such transaction, an "**Alternative Transaction**"), then during the term of this Agreement the Securityholder may, on its own accord, and shall, upon written request of USBTC, support the completion of such Alternative Transaction in the same manner as the transactions contemplated in the Business Combination Agreement in accordance with the terms and conditions of this Agreement, including by (A) if applicable, depositing or causing the deposit of its Subject Securities, into an Alternative Transaction conducted by way of a take-over bid made by USBTC or an Affiliate of USBTC and not withdrawing them; and/ or (B) voting or causing to be voted all of the Subject Securities (to the extent that they carry the right to vote) in favour of, and not dissenting from (to the extent dissent rights are available under applicable law), such Alternative Transaction proposed by USBTC and, in the event of any such proposed Alternative Transaction, the references in this Agreement to the "Arrangement" shall be deemed to be changed to "Alternative Transaction" and all terms, covenants, representations and warranties of this Agreement shall be and shall be deemed to have been made in the context of the Alternative Transaction.

**ARTICLE 4<br> GENERAL**

**4.1** **Termination** 

This Agreement shall automatically terminate and be of no further force or effect only upon the earliest of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the written agreement of USBTC and the Securityholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the date and time the Business Combination Agreement is terminated in accordance with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) written notice by the Securityholder to USBTC if, without the prior written consent of the Securityholder,
there is any decrease in the aggregate amount of the Hut Consideration to be received by non-dissenting Hut Shareholders under the terms
of the Arrangement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Effective Time.

Any such termination of this Agreement in accordance with this Section 4.1 shall render the provisions of this Agreement of no further force and effect and no party shall have any further liability or obligations to any other party hereunder, provided however that such termination shall not prejudice the rights of a party as a result of a breach by any other party of its obligations hereunder occurring prior to such termination.

**4.2** **Time of the Essence** 

Time is of the essence in the performance of the parties' respective obligations.

**4.3** **Amendment** 

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

**4.4** **Equitable Relief** 

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, USBTC shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

**4.8** **Notices**

**4.11** **Fees and Expenses** 

Each party shall pay all fees, costs and expenses incurred by such party in connection with this Agreement.

**4.12** **Independent Legal Advice**

Each of the parties will, from time to time, execute and deliver all such further documents and instruments and do all such acts and things as the other party may reasonably require and at the requesting party's cost (it being agreed that the requesting party will only be responsible for the reasonable, out-of-pocket costs incurred by the incurring party) to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement.

**4.14** **Counterparts** 

This Agreement may be executed in any number of counterparts (including counterparts by facsimile) and all such counterparts taken together shall be deemed to constitute one and the same instrument.

contemplated hereby or the compliance by the Securityholder with the Securityholder's obligations hereunder will violate, contravene,
result in any breach of, or be in conflict with, or constitute a default under, or create a state of facts which after notice or lapse
of time or both would constitute a default under: (i) any Contract to which the Securityholder is a party or by which the Securityholder
or any of the property or assets of the Securityholder are bound; (ii) any judgment, decree, order or award of any Governmental Entity;
or (iii) any applicable Laws, except as would not, individually or in the aggregate, reasonably be expected to materially adversely

or by, or filing with, or notification to any Governmental Entity which has not been made or obtained is required to be made or obtained

this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) This Agreement has been duly executed and delivered by USBTC, and, assuming the due execution and delivery
by the Securityholder, constitutes a legal, valid and binding agreement of USBTC enforceable against it in accordance with its terms subject

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) There are no claims, actions, suits, audits, proceedings, investigations or other actions pending against,
or, to the knowledge of USBTC, threated against or affecting USBTC that, individually or in the aggregate, could reasonably be expected

**ARTICLE 3<br> COVENANTS**

**3.1** **Covenants of the Securityholder** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Securityholder hereby irrevocably and unconditionally covenants with USBTC that, from the date of
this Agreement until the termination of this Agreement in accordance with its terms (the "**Expiry Time** "), the Securityholder

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) sell, transfer, gift, assign, convey, pledge, hypothecate, encumber, option, grant a security interest
in or otherwise dispose of any right or interest in (including by way of deposit or tender under any take-over bid) any of the Subject
Securities, or enter into any agreement, arrangement or understanding in connection therewith (whether by actual disposition or effective
economic disposition due to cash settlement or otherwise), other than (A) pursuant to the Arrangement, Business Combination Agreement
or an Alternative Transaction, (B) any exercise or settlement, as applicable, of Hut Options, Hut DSUs, or Hut RSUs for Hut Shares
in accordance with their terms including any disposition thereof for tax purposes or for purposes of "sell-to-cover" transactions,
or (C) without affecting beneficial ownership or control or direction over the Subject Securities, to one or more corporations directly
or indirectly wholly owned by the Securityholder or to any member of the Securityholder's immediate family or to a trust, partnership,
limited liability company, or other similar estate planning vehicle for the benefit of the Securityholder or any member of the Securityholder's
immediate family, pursuant to a will, testamentary document or intestate succession upon the death of a Securityholder who is an individual
or pursuant to a family court order (each, a "**Permitted Transfer** "), provided that in each case and for greater certainty,
any Hut Shares acquired as a result thereof shall be Subject Securities and subject to the terms and conditions of this Agreement,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) requisition or join in the requisition of any meeting of any of the Hut Shareholders for the purpose of
considering any resolution, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) other than as set forth herein, grant any proxies or powers of attorney, deposit any Subject Securities
into a voting trust, in any way transfer any of the voting rights associated with any of the Subject Securities, or enter into a voting
agreement, understanding or arrangement with respect to the voting, the right to vote, call meetings of the Hut Shareholders or give consents
or approval of any kind with respect to any Subject Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Securityholder hereby covenants, undertakes and agrees, from the date of this Agreement until the
Expiry Time, to vote (or cause to be voted) all the Subject Securities at any meeting of any of the Hut Shareholders at which the Securityholder
is entitled to vote in respect of such Subject Securities, including without limitation the Hut Meeting, and in any action by written
consent of the Hut Shareholders:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in favour of the approval, consent, ratification and adoption of the Arrangement (including, without limitation,
the Arrangement Resolution) and the transactions contemplated by the Business Combination Agreement (and any actions reasonably required
for the consummation of the transactions contemplated by the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) against (A) any Acquisition Proposal (other than the transactions contemplated by the Business Combination
Agreement); and (B) any action that would reasonably be expected to impede, delay, interfere with, or discourage in any material
respect the transactions contemplated by the Business Combination Agreement and any action that would reasonably be expected to result
in any material breach of any representation, warranty or covenant of Hut in the Business Combination Agreement.

In connection with the foregoing, subject to this Section 3.1(b), the Securityholder hereby irrevocably and unconditionally agrees to deposit an irrevocable proxy or voting instruction form, duly completed and executed in respect of all of the Subject Securities, at least ten Business Days prior to the Hut Meeting, voting all such Subject Securities in favour of the Arrangement Resolution. The Securityholder hereby irrevocably and unconditionally agrees that neither it nor any Person on its behalf will take any action to withdraw, amend or invalidate any proxy or voting instruction form deposited or delivered by the Securityholder pursuant to this Agreement notwithstanding any statutory or other rights which the Securityholder might have unless this Agreement is terminated in accordance with Section 4.1. If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Securityholder hereby covenants, undertakes and agrees to immediately cease and cause to be terminated
any existing solicitation, discussion or negotiation commenced prior to the date of this Agreement with any Person (other than USBTC or
an Affiliate thereof) by such Securityholder or, if applicable, any of its officers, directors, employees, representatives or agents with
respect to any potential Acquisition Proposal (other than the transactions contemplated by the Business Combination Agreement), whether
or not initiated by the Securityholder or any of its officers, directors, employees, representatives or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Subject to the terms and conditions of this Agreement (including, for the avoidance of doubt, Section 4.5)
or except as may be expressly permitted by the Business Combination Agreement or by USBTC in writing, the Securityholder agrees, until
the Expiry Time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) not to exercise any rights of appraisal, Dissent Rights or other rights of dissent that the Securityholder
may have arising from the transactions contemplated by the Business Combination Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) not to bring, or threaten to bring, any suit or proceeding for the purpose of, or which has the effect

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) not to solicit, initiate or otherwise knowingly facilitate any inquiry, proposal or offer that constitutes
or may reasonably be expected to constitute or lead to, an Acquisition Proposal (other than an Acquisition Proposal made by USBTC or an
Affiliate of USBTC pursuant to the Business Combination Agreement);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) not to participate in any discussions or negotiations with any Person (other than USBTC or an Affiliate
of USBTC) regarding any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an Acquisition
Proposal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) not to accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement,
arrangement or understanding related to any Acquisition Proposal (other than an Acquisition Proposal made by USBTC or an Affiliate of
USBTC pursuant to the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) not to cooperate in any way with, or knowingly assist or participate in, any effort or attempt by any
other Person to do or seek to do any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Securityholder hereby irrevocably consents to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) details of this Agreement being set out in any information circular or U.S. registration statement and
court documents produced by Hut, USBTC or any of their respective Affiliates in connection with the transactions contemplated by this
Agreement and the Business Combination Agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) this Agreement or details of this Agreement otherwise being made publicly available, including by filing
on the System for Electronic Document Analysis and Retrieval (SEDAR) operated on behalf of the Securities Authority and the Electronic

Agreement, the Securityholder shall not make any public announcement or statement with respect to the transactions contemplated herein
or pursuant to the Business Combination Agreement without the prior written approval of USBTC.

**3.2** **Covenants of USBTC** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) USBTC hereby agrees and confirms to the Securityholder that it shall take all steps required of it under
the Business Combination Agreement to consummate the transactions contemplated by the Business Combination Agreement (including the Arrangement)
and to cause New Hut to deliver the Hut Consideration Shares to the Depositary, in each case in accordance with and subject to the terms
and conditions of the Business Combination Agreement and the Plan of Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The obligation of USBTC to complete the transactions contemplated by the Business Combination Agreement
(including the Arrangement) shall be subject to the conditions set forth in the Business Combination Agreement.

**3.3** **Co-operation/Alternative Transaction** 

In the event that, in lieu of or in conjunction with the Arrangement, USBTC seeks to complete the transactions contemplated in the Business Combination Agreement other than as contemplated by this Agreement and the Business Combination Agreement on a basis that (a) provides for economic terms which, in relation to the Securityholder, on an after-tax basis, are at least equivalent to or better than those contemplated by this Agreement and the Business Combination Agreement, (b) would not likely result in a delay or time to completion beyond the Outside Date, and (c) is otherwise on terms and conditions not materially more onerous on the Securityholder than the transactions contemplated in the Business Combination (any such transaction, an "**Alternative Transaction**"), then during the term of this Agreement the Securityholder may, on its own accord, and shall, upon written request of USBTC, support the completion of such Alternative Transaction in the same manner as the transactions contemplated in the Business Combination Agreement in accordance with the terms and conditions of this Agreement, including by (A) if applicable, depositing or causing the deposit of its Subject Securities, into an Alternative Transaction conducted by way of a take-over bid made by USBTC or an Affiliate of USBTC and not withdrawing them; and/ or (B) voting or causing to be voted all of the Subject Securities (to the extent that they carry the right to vote) in favour of, and not dissenting from (to the extent dissent rights are available under applicable law), such Alternative Transaction proposed by USBTC and, in the event of any such proposed Alternative Transaction, the references in this Agreement to the "Arrangement" shall be deemed to be changed to "Alternative Transaction" and all terms, covenants, representations and warranties of this Agreement shall be and shall be deemed to have been made in the context of the Alternative Transaction.

**ARTICLE 4<br> GENERAL**

**4.1** **Termination** 

This Agreement shall automatically terminate and be of no further force or effect only upon the earliest of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the written agreement of USBTC and the Securityholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the date and time the Business Combination Agreement is terminated in accordance with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) written notice by the Securityholder to USBTC if, without the prior written consent of the Securityholder,
there is any decrease in the aggregate amount of the Hut Consideration to be received by non-dissenting Hut Shareholders under the terms
of the Arrangement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Effective Time.

Any such termination of this Agreement in accordance with this Section 4.1 shall render the provisions of this Agreement of no further force and effect and no party shall have any further liability or obligations to any other party hereunder, provided however that such termination shall not prejudice the rights of a party as a result of a breach by any other party of its obligations hereunder occurring prior to such termination.

**4.2** **Time of the Essence** 

Time is of the essence in the performance of the parties' respective obligations.

**4.3** **Amendment** 

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

**4.4** **Equitable Relief** 

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, USBTC shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

**4.8** **Notices** 

Any notice, or other communication given regarding the matters contemplated by this Agreement must be in writing, sent by personal delivery, courier, facsimile or electronic mail and addressed:

Sending a copy of a notice or other communication to a party's legal counsel as contemplated above is for information purposes only and does not constitute delivery of the notice or other communication to that party. The failure to send a copy of a notice or other communication to legal counsel does not invalidate delivery of that notice or other communication to a party.

**4.9** **Severability** 

If any provision of this Agreement is determined to be illegal, invalid or unenforceable by any court of competent jurisdiction, that provision will be severed from this Agreement and the remaining provisions shall remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

**4.10** **Successors and Assigns**

**4.11** **Fees and Expenses** 

Each party shall pay all fees, costs and expenses incurred by such party in connection with this Agreement.

**4.12** **Independent Legal Advice**

**4.13** **Further Assurances** 

Each of the parties will, from time to time, execute and deliver all such further documents and instruments and do all such acts and things as the other party may reasonably require and at the requesting party's cost (it being agreed that the requesting party will only be responsible for the reasonable, out-of-pocket costs incurred by the incurring party) to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement.

**4.14** **Counterparts** 

This Agreement may be executed in any number of counterparts (including counterparts by facsimile) and all such counterparts taken together shall be deemed to constitute one and the same instrument. The parties shall be entitled to rely upon delivery of an executed facsimile or similar executed electronic copy of this Agreement, and such facsimile or similar executed electronic copy shall be legally effective to create a valid and binding agreement between the parties.

contemplated hereby or the compliance by the Securityholder with the Securityholder's obligations hereunder will violate, contravene,
result in any breach of, or be in conflict with, or constitute a default under, or create a state of facts which after notice or lapse

or any of the property or assets of the Securityholder are bound; (ii) any judgment, decree, order or award of any Governmental Entity;
or (iii) any applicable Laws, except as would not, individually or in the aggregate, reasonably be expected to materially adversely

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Securityholder hereby irrevocably and unconditionally covenants with USBTC that, from the date of
this Agreement until the termination of this Agreement in accordance with its terms (the "**Expiry Time** "), the Securityholder

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) sell, transfer, gift, assign, convey, pledge, hypothecate, encumber, option, grant a security interest
in or otherwise dispose of any right or interest in (including by way of deposit or tender under any take-over bid) any of the Subject
Securities, or enter into any agreement, arrangement or understanding in connection therewith (whether by actual disposition or effective
economic disposition due to cash settlement or otherwise), other than (A) pursuant to the Arrangement, Business Combination Agreement
or an Alternative Transaction, (B) any exercise or settlement, as applicable, of Hut Options, Hut DSUs, or Hut RSUs for Hut Shares
in accordance with their terms including any disposition thereof for tax purposes or for purposes of "sell-to-cover" transactions,

or indirectly wholly owned by the Securityholder or to any member of the Securityholder's immediate family or to a trust, partnership,
limited liability company, or other similar estate planning vehicle for the benefit of the Securityholder or any member of the Securityholder's
immediate family, pursuant to a will, testamentary document or intestate succession upon the death of a Securityholder who is an individual
or pursuant to a family court order (each, a "**Permitted Transfer** "), provided that in each case and for greater certainty,
any Hut Shares acquired as a result thereof shall be Subject Securities and subject to the terms and conditions of this Agreement,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) requisition or join in the requisition of any meeting of any of the Hut Shareholders for the purpose of
considering any resolution, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) other than as set forth herein, grant any proxies or powers of attorney, deposit any Subject Securities
into a voting trust, in any way transfer any of the voting rights associated with any of the Subject Securities, or enter into a voting
agreement, understanding or arrangement with respect to the voting, the right to vote, call meetings of the Hut Shareholders or give consents
or approval of any kind with respect to any Subject Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Securityholder hereby covenants, undertakes and agrees, from the date of this Agreement until the
Expiry Time, to vote (or cause to be voted) all the Subject Securities at any meeting of any of the Hut Shareholders at which the Securityholder
is entitled to vote in respect of such Subject Securities, including without limitation the Hut Meeting, and in any action by written
consent of the Hut Shareholders:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in favour of the approval, consent, ratification and adoption of the Arrangement (including, without limitation,
the Arrangement Resolution) and the transactions contemplated by the Business Combination Agreement (and any actions reasonably required
for the consummation of the transactions contemplated by the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) against (A) any Acquisition Proposal (other than the transactions contemplated by the Business Combination
Agreement); and (B) any action that would reasonably be expected to impede, delay, interfere with, or discourage in any material
respect the transactions contemplated by the Business Combination Agreement and any action that would reasonably be expected to result
in any material breach of any representation, warranty or covenant of Hut in the Business Combination Agreement.

In connection with the foregoing, subject to this Section 3.1(b), the Securityholder hereby irrevocably and unconditionally agrees to deposit an irrevocable proxy or voting instruction form, duly completed and executed in respect of all of the Subject Securities, at least ten Business Days prior to the Hut Meeting, voting all such Subject Securities in favour of the Arrangement Resolution. The Securityholder hereby irrevocably and unconditionally agrees that neither it nor any Person on its behalf will take any action to withdraw, amend or invalidate any proxy or voting instruction form deposited or delivered by the Securityholder pursuant to this Agreement notwithstanding any statutory or other rights which the Securityholder might have unless this Agreement is terminated in accordance with Section 4.1. If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Securityholder hereby covenants, undertakes and agrees to immediately cease and cause to be terminated
any existing solicitation, discussion or negotiation commenced prior to the date of this Agreement with any Person (other than USBTC or
an Affiliate thereof) by such Securityholder or, if applicable, any of its officers, directors, employees, representatives or agents with
respect to any potential Acquisition Proposal (other than the transactions contemplated by the Business Combination Agreement), whether
or not initiated by the Securityholder or any of its officers, directors, employees, representatives or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Subject to the terms and conditions of this Agreement (including, for the avoidance of doubt, Section 4.5)
or except as may be expressly permitted by the Business Combination Agreement or by USBTC in writing, the Securityholder agrees, until
the Expiry Time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) not to exercise any rights of appraisal, Dissent Rights or other rights of dissent that the Securityholder
may have arising from the transactions contemplated by the Business Combination Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) not to bring, or threaten to bring, any suit or proceeding for the purpose of, or which has the effect
of, directly or indirectly, stopping, preventing, impeding, delaying or varying in any material respect such transactions or any aspect
thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) not to take any action of any kind, directly or indirectly, which might reasonably be regarded as likely

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) to cooperate with Hut and USBTC to successfully complete the Arrangement and the other transactions contemplated
by the Business Combination Agreement and this Agreement, and to oppose any of the matters in Section 3.1(b)(ii);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) not to solicit, initiate or otherwise knowingly facilitate any inquiry, proposal or offer that constitutes
or may reasonably be expected to constitute or lead to, an Acquisition Proposal (other than an Acquisition Proposal made by USBTC or an
Affiliate of USBTC pursuant to the Business Combination Agreement);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) not to participate in any discussions or negotiations with any Person (other than USBTC or an Affiliate
of USBTC) regarding any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an Acquisition
Proposal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) not to accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement,
arrangement or understanding related to any Acquisition Proposal (other than an Acquisition Proposal made by USBTC or an Affiliate of
USBTC pursuant to the Business Combination Agreement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) not to cooperate in any way with, or knowingly assist or participate in, any effort or attempt by any
other Person to do or seek to do any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Securityholder hereby irrevocably consents to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) details of this Agreement being set out in any information circular or U.S. registration statement and
court documents produced by Hut, USBTC or any of their respective Affiliates in connection with the transactions contemplated by this
Agreement and the Business Combination Agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) this Agreement or details of this Agreement otherwise being made publicly available, including by filing

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) USBTC hereby agrees and confirms to the Securityholder that it shall take all steps required of it under
the Business Combination Agreement to consummate the transactions contemplated by the Business Combination Agreement (including the Arrangement)
and to cause New Hut to deliver the Hut Consideration Shares to the Depositary, in each case in accordance with and subject to the terms
and conditions of the Business Combination Agreement and the Plan of Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The obligation of USBTC to complete the transactions contemplated by the Business Combination Agreement
(including the Arrangement) shall be subject to the conditions set forth in the Business Combination Agreement.

**3.3** **Co-operation/Alternative Transaction** 

In the event that, in lieu of or in conjunction with the Arrangement, USBTC seeks to complete the transactions contemplated in the Business Combination Agreement other than as contemplated by this Agreement and the Business Combination Agreement on a basis that (a) provides for economic terms which, in relation to the Securityholder, on an after-tax basis, are at least equivalent to or better than those contemplated by this Agreement and the Business Combination Agreement, (b) would not likely result in a delay or time to completion beyond the Outside Date, and (c) is otherwise on terms and conditions not materially more onerous on the Securityholder than the transactions contemplated in the Business Combination (any such transaction, an "**Alternative Transaction**"), then during the term of this Agreement the Securityholder may, on its own accord, and shall, upon written request of USBTC, support the completion of such Alternative Transaction in the same manner as the transactions contemplated in the Business Combination Agreement in accordance with the terms and conditions of this Agreement, including by (A) if applicable, depositing or causing the deposit of its Subject Securities, into an Alternative Transaction conducted by way of a take-over bid made by USBTC or an Affiliate of USBTC and not withdrawing them; and/ or (B) voting or causing to be voted all of the Subject Securities (to the extent that they carry the right to vote) in favour of, and not dissenting from (to the extent dissent rights are available under applicable law), such Alternative Transaction proposed by USBTC and, in the event of any such proposed Alternative Transaction, the references in this Agreement to the "Arrangement" shall be deemed to be changed to "Alternative Transaction" and all terms, covenants, representations and warranties of this Agreement shall be and shall be deemed to have been made in the context of the Alternative Transaction.

**ARTICLE 4<br> GENERAL**

**4.1** **Termination** 

This Agreement shall automatically terminate and be of no further force or effect only upon the earliest of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the written agreement of USBTC and the Securityholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the date and time the Business Combination Agreement is terminated in accordance with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) written notice by the Securityholder to USBTC if, without the prior written consent of the Securityholder,
there is any decrease in the aggregate amount of the Hut Consideration to be received by non-dissenting Hut Shareholders under the terms
of the Arrangement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Effective Time.

Any such termination of this Agreement in accordance with this Section 4.1 shall render the provisions of this Agreement of no further force and effect and no party shall have any further liability or obligations to any other party hereunder, provided however that such termination shall not prejudice the rights of a party as a result of a breach by any other party of its obligations hereunder occurring prior to such termination.

**4.2** **Time of the Essence** 

Time is of the essence in the performance of the parties' respective obligations.

**4.3** **Amendment** 

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

**4.4** **Equitable Relief** 

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, USBTC shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

**4.8** **Notices**

**4.11** **Fees and Expenses** 

Each party shall pay all fees, costs and expenses incurred by such party in connection with this Agreement.

**4.12** **Independent Legal Advice**

**4.13** **Further Assurances** 

Each of the parties will, from time to time, execute and deliver all such further documents and instruments and do all such acts and things as the other party may reasonably require and at the requesting party's cost (it being agreed that the requesting party will only be responsible for the reasonable, out-of-pocket costs incurred by the incurring party) to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement.

**4.14** **Counterparts** 

This Agreement may be executed in any number of counterparts (including counterparts by facsimile) and all such counterparts taken together shall be deemed to constitute one and the same instrument.

or approval of any kind with respect to any Subject Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Securityholder hereby covenants, undertakes and agrees, from the date of this Agreement until the

consent of the Hut Shareholders:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in favour of the approval, consent, ratification and adoption of the Arrangement (including, without limitation,

If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Securityholder hereby covenants, undertakes and agrees to immediately cease and cause to be terminated

respect to any potential Acquisition Proposal (other than the transactions contemplated by the Business Combination Agreement), whether
or not initiated by the Securityholder or any of its officers, directors, employees, representatives or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Subject to the terms and conditions of this Agreement (including, for the avoidance of doubt, Section 4.5)

**ARTICLE 4<br> GENERAL**

**4.1** **Termination** 

This Agreement shall automatically terminate and be of no further force or effect only upon the earliest of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the written agreement of USBTC and the Securityholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the date and time the Business Combination Agreement is terminated in accordance with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) written notice by the Securityholder to USBTC if, without the prior written consent of the Securityholder,
there is any decrease in the aggregate amount of the Hut Consideration to be received by non-dissenting Hut Shareholders under the terms
of the Arrangement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Effective Time.

Any such termination of this Agreement in accordance with this Section 4.1 shall render the provisions of this Agreement of no further force and effect and no party shall have any further liability or obligations to any other party hereunder, provided however that such termination shall not prejudice the rights of a party as a result of a breach by any other party of its obligations hereunder occurring prior to such termination.

**4.2** **Time of the Essence** 

Time is of the essence in the performance of the parties' respective obligations.

**4.3** **Amendment** 

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

**4.4** **Equitable Relief** 

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, USBTC shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

Any notice or other communication is deemed to be given and received (i) if sent by personal delivery or same day courier, on the date of delivery if it is a Business Day and the delivery was made prior to 5:00 p.m. (local time in place of receipt) and otherwise on the next Business Day, (ii) if sent by overnight courier, on the next Business Day, (iii) if sent by facsimile, on the Business Day following the date of confirmation of transmission by the originating facsimile, or (iv) if sent by electronic mail, when the sender receives an email from the recipient acknowledging receipt, provided that an automatic "read receipt" does not constitute acknowledgment of an email for purposes of this Section 4.8. Sending a copy of a notice or other communication to a party's legal counsel as contemplated above is for information purposes only and does not constitute delivery of the notice or other communication to that party. The failure to send a copy of a notice or other communication to legal counsel does not invalidate delivery of that notice or other communication to a party.

**4.9** **Severability** 

If any provision of this Agreement is determined to be illegal, invalid or unenforceable by any court of competent jurisdiction, that provision will be severed from this Agreement and the remaining provisions shall remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

**4.10** **Successors and Assigns** 

The provisions of this Agreement shall be binding upon and enure to the benefit of the parties hereto and their respective successors, permitted assigns and legal personal representatives, provided that, except as permitted by Section 3.1(a)(i) in connection with a Permitted Transfer (provided that the Securityholder shall continue to be liable jointly and severally with the transferee(s) to such Permitted Transfer), no party may assign, delegate or otherwise transfer any of its rights, interests or obligations under this Agreement without the prior written consent of the other parties hereto, provided that USBTC may assign all or part of its right under this Agreement to, and its obligations under this Agreement may be assumed by, any of its Affiliates, provided that if such agreement and/or assumption takes place, USBTC shall continue to be liable jointly and severally with such Affiliate, as the case may be, for all of its obligations hereunder, without the consent of the Securityholder.

**4.11** **Fees and Expenses** 

Each party shall pay all fees, costs and expenses incurred by such party in connection with this Agreement.

**4.12** **Independent Legal Advice** 

The Securityholder acknowledges that it has been afforded the opportunity to obtain independent legal advice and confirms by the execution of this Agreement that it has either done so or waived its right to do so in connection with the entering into of this Agreement.

**4.13** **Further Assurances** 

Each of the parties will, from time to time, execute and deliver all such further documents and instruments and do all such acts and things as the other party may reasonably require and at the requesting party's cost (it being agreed that the requesting party will only be responsible for the reasonable, out-of-pocket costs incurred by the incurring party) to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement.

**4.14** **Counterparts** 

This Agreement may be executed in any number of counterparts (including counterparts by facsimile) and all such counterparts taken together shall be deemed to constitute one and the same instrument. The parties shall be entitled to rely upon delivery of an executed facsimile or similar executed electronic copy of this Agreement, and such facsimile or similar executed electronic copy shall be legally effective to create a valid and binding agreement between the parties.

contemplated hereby or the compliance by the Securityholder with the Securityholder's obligations hereunder will violate, contravene,
result in any breach of, or be in conflict with, or constitute a default under, or create a state of facts which after notice or lapse

or any of the property or assets of the Securityholder are bound; (ii) any judgment, decree, order or award of any Governmental Entity;

or approval of any kind with respect to any Subject Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Securityholder hereby covenants, undertakes and agrees, from the date of this Agreement until the
Expiry Time, to vote (or cause to be voted) all the Subject Securities at any meeting of any of the Hut Shareholders at which the Securityholder

consent of the Hut Shareholders:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in favour of the approval, consent, ratification and adoption of the Arrangement (including, without limitation,

If for any reason such proxy or voting instruction form is invalid and not effective, as determined by the Depositary, or is not delivered in accordance with this Section 3.1(b), the Securityholder hereby unconditionally and irrevocably appoints USBTC as attorney in fact (which appointment is coupled with an interest) for and on its behalf to act in respect of any resolution in connection with the Arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Securityholder hereby covenants, undertakes and agrees to immediately cease and cause to be terminated
any existing solicitation, discussion or negotiation commenced prior to the date of this Agreement with any Person (other than USBTC or

respect to any potential Acquisition Proposal (other than the transactions contemplated by the Business Combination Agreement), whether
or not initiated by the Securityholder or any of its officers, directors, employees, representatives or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Subject to the terms and conditions of this Agreement (including, for the avoidance of doubt, Section 4.5)

**4.2** **Time of the Essence** 

Time is of the essence in the performance of the parties' respective obligations.

**4.3** **Amendment** 

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

**4.4** **Equitable Relief** 

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, USBTC shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party's right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

**4.5** **Fiduciary Duties** 

USBTC agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder of Hut and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholders in his or her capacity as a director or officer of Hut or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his or her fiduciary duties as a director or officer of Hut.

**4.6** **Waiver** 

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party's failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

**4.7** **Entire Agreement** 

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

All information, other than statements of historical facts, included in this presentation that address activities, events or developments that Hut 8 Mining Corp. ("Hut 8") expects or anticipates will or may occur in the future, including such things as future business strategy, competitive strengths, goals, expansion and growth of Hut 8's businesses, operations, plans and other such matters is forward looking information. Forward-looking information is often identified by the words "may", "would", "could", "should", "will", "intend", "plan", "anticipate", "allow", "believe", "estimate", "expect", "predict", "can", "might", "potential", "predict", "is designed to", "likely" or similar expressions. In addition, any statements in this presentation that refer to expectations, projections or other characterizations of future events or circumstances contain forward-looking information and include, among others, statements with respect to: (i) the expected outcomes of the merger, including the combined company's ("New Hut") assets and financial position; (ii) the ability of Hut 8 and U.S. Data Mining Group, Inc. dba US Bitcoin Corp ("USBTC") to complete the merger on the terms described herein, or at all, including, receipt of required regulatory approvals, shareholder approvals, court approvals, stock exchange approvals and satisfaction of other closing customary conditions; (iii) the expected synergies related to the merger in respect of strategy, operations and other matters; (iv) projections related to expansion; (v) expectations related to New Hut's hashrate and self-mining capacity; (vi) acceleration of ESG efforts and commitments; and (vii) the ability of New Hut to execute on future opportunities, among others. Statements containing forward-looking information are not historical facts, but instead represent management's expectations, estimates and projections regarding future events based on certain material factors and assumptions at the time the statement was made. While considered reasonable by Hut 8 and USBTC as of the date of this presentation, such statements are subject to known and unknown risks, uncertainties, assumptions and other factors that may cause the actual results, level of activity, performance or achievements to be materially different from those expressed or implied by such forward-looking information, including but not limited to: the ability to obtain requisite shareholder approvals and the satisfaction of other conditions to the consummation of the Transaction on the proposed terms or at all; the ability to obtain necessary stock exchange, regulatory, governmental or other approvals in the time assumed or at all; the anticipated timeline for the completion of the Transaction; the ability to realize the anticipated benefits of the Transaction or implementing the business plan for the Combined Company, including as a result of a delay in completing the Transaction or difficulty in integrating the businesses of the companies involved (including the retention of key employees); the ability to realize synergies and cost savings at the times, and to the extent, anticipated; the potential impact on mining activities; the potential impact of the announcement or consummation of the Transaction on relationships, including with regulatory bodies, employees, suppliers, customers, competitors and other key stakeholders; the outcome of any litigation proceedings in respect of USBTC's legal dispute with the City of Niagara Falls, New York; security and cybersecurity threats and hacks; malicious actors or botnet obtaining control of processing power on the Bitcoin network; further development and acceptance of the Bitcoin network; changes to Bitcoin mining difficulty; loss or destruction of private keys; increases in fees for recording transactions in the Blockchain; internet and power disruptions; geopolitical events; uncertainty in the development of cryptographic and algorithmic protocols; uncertainty about the acceptance or widespread use of digital assets; failure to anticipate technology innovations; the COVID-19 pandemic; climate change; currency risk; lending risk and recovery of potential losses; litigation risk; changes in market demand; changes in network and infrastructure; system interruption; changes in leasing arrangements; failure to achieve intended benefits of power purchase agreements; potential for interrupted delivery, or suspension of the delivery, of energy to New Hut's mining sites. These risks are not intended to represent a complete list of the factors that could affect Hut 8, USBTC, or New Hut 8; however, these factors should be considered carefully. There can be no assurance that such estimates and assumptions will prove to be correct. Should one or more of these risks or uncertainties materialize, or should assumptions underlying the forward-looking statements prove incorrect, actual results may vary materially from those described in this presentation as intended, planned, anticipated, believed, sought, proposed, estimated, forecasted, expected, projected or targeted and such forward-looking statements included in this presentation should not be unduly relied upon. The impact of any one assumption, risk, uncertainty, or other factor on a particular forward-looking statement cannot be determined with certainty because they are interdependent and New Hut's future decisions and actions will depend on management's assessment of all information at the relevant time. The forward-looking statements contained in this presentation are made as of the date of this presentation, and Hut 8 and USBTC expressly disclaim any obligation to update or alter statements containing any forward-looking information, or the factors or assumptions underlying them, whether as a result of new information, future events or otherwise, except as required by law. Except where otherwise indicated herein, the information provided herein is based on matters as they exist as of the date of preparation and not as of any future date, and will not be updated or otherwise revised to reflect information that subsequently becomes available, or circumstances existing or changes occurring after the date of preparation. |

Currency All amounts in this presentation are expressed in United States dollars unless otherwise noted. NOTE REGARDING CERTAIN FINANCIAL MEASURES AND KEY METRICS This presentation makes reference to certain measures that are not recognized under International Financial Reporting Standards ("IFRS") and do not have a standardized meaning prescribed by IFRS and therefore, are considered non-IFRS measures. They are not necessarily comparable to similar measures presented by other companies. Hut 8 uses non-IFRS measures including "EBITDA", "adjusted EBITDA" and "mining profit" as additional information to complement IFRS measures by providing further understanding of Hut 8's results of operations from management's perspective. These non-IFRS financial performance measures are included because management has used the information to analyze the combined business performance and financial position of New Hut. These non-IFRS financial measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. In order to provide the business performance and financial position of New Hut, certain non-IFRS financial performance measures of each of Hut 8 and USBTC have been combined to show an aggregate number. Definitions and reconciliations of such measure can be found in Hut 8's annual Management's Discussion and Analysis for the year ended December 31, 2021, filed under its profile on SEDAR (www.sedar.com) and included in its Form 40-F filed on EDGAR (www.sec.gov). Note to Readers This presentation may not be reproduced, further distributed or published in whole or in part by any other person. Neither this presentation nor any copy of it may be taken or transmitted into or distributed in any other jurisdiction which prohibits the same except in compliance with applicable laws. Any failure to comply with this restriction may constitute a violation of applicable securities law. Recipients are required to inform themselves of, and comply with, all such restrictions or prohibitions and Hut 8 and USBTC do not accept liability to any person in relation thereto. Additional Information about the Proposed Transaction and Where to Find It In connection with the proposed transaction, that, if completed, would result in New Hut becoming a public company (the "Transaction"), New Hut is expected to file a registration statement on Form S-4 (the "Form S-4") with the U.S. Securities and Exchange Commission (the "SEC"). Hut 8 and USBTC urge investors, shareholders, and other interested persons to read, when available, the Form S-4, including amendments thereto, the Hut 8 meeting circular, as well as other documents to be filed with the SEC and documents to be filed with Canadian securities regulatory authorities in connection with the Transaction, as these materials will contain important information about Hut 8, USBTC, New Hut, and the Transaction. New Hut also has, and will, file other documents regarding the Transaction with the SEC. This presentation is not a substitute for the Form S-4 or any other documents that may be sent to Hut 8's shareholders or USBTC's stockholders in connection with the Transaction. Investors and security holders will be able to obtain free copies of the Form S-4 and all other relevant documents filed or that will be filed with the SEC by New Hut through the website maintained by the SEC at www.sec.gov or by contacting the Investor Relations department of Hut 8 at info@hut8.io and USBTC at info@usbitcoin.com. No Offer or Solicitation This presentation is not intended to and shall not constitute an offer to sell or the solicitation of an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended (the "Securities Act") or in a transaction exempt from the registration requirements of the Securities Act. |
