Covenants of the Securityholder

(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:

(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,

(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:

(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.

ARTICLE 4
GENERAL

4.1

Termination

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

(a)

the written agreement of USBTC and the Securityholder;

(b)

the date and time the Business Combination Agreement is terminated in accordance with its terms;

(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

(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.

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.

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

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.
