The Company shall cause the Resale Shelf Registration Statement to be declared effective under the Securities Act as soon as reasonably practicable, and shall use its reasonable best efforts to keep each such Resale Shelf Registration Statement continuously effective during its entire Effectiveness Period. Following the Effective Date of the Resale Shelf Registration Statement, the Company shall file with the Commission in accordance with Rule 424 the final Prospectus to be used in connection with sales pursuant to such Resale Shelf Registration Statement (whether or not such filing is technically required under such Rule) in accordance with the requirements of Rule 424.

(b)Following any date on which the Company becomes eligible to use a registration statement on Form S-3 (and provided it is not subject to any other restrictions from filing or otherwise using a registration statement on Form S-3) to register Registrable Securities for resale, the Company shall file a Registration Statement on Form S-3 covering all securities that are then deemed Registrable Securities (or a post-effective amendment on Form S-3 to the then effective Registration Statement) for an offering to be made on a continuous basis pursuant to Rule 415 (an “S-3 Resale Shelf Registration Statement”) and shall cause such S-3 Resale Shelf Registration Statement to be filed as soon as commercially reasonable and declared effective under the Securities Act as soon as reasonably possible thereafter.

The Company shall use its commercially reasonable efforts to keep such S-3 Resale Shelf Registration Statement continuously

3

effective under the Securities Act during the entire Effectiveness Period. Following the Effective Date of such S-3 Resale Shelf Registration Statement, the Company shall file with the Commission in accordance with Rule 424 the final Prospectus to be used in connection with sales pursuant to such S-3 Resale Shelf Registration Statement (whether or not such filing is technically required under such Rule) in accordance with the requirements of Rule 424.

(c)Each Holder agrees to furnish to the Company a completed Selling Holder Questionnaire in the form attached to this Agreement as Annex B. The Company shall not be required to include the Registrable Securities of a Holder in any Registration Statement if such Holder fails to furnish to the Company a fully completed Selling Holder Questionnaire at least two Business Days prior to the filing of the Resale Shelf Registration Statement or S-3 Resale Shelf Registration Statement (subject to the requirements set forth in Section 3(a)).

(d)Each Holder will deliver, upon execution of this Agreement, an executed lock-up agreement (the “Lock-Up Agreement”) in the form attached hereto as Annex C.

3. Registration Procedures. In connection with the Company’s registration obligations hereunder:

(a) The Company shall not file a Registration Statement, any Prospectus or any amendments or supplements thereto in which the “Selling Stockholder” section thereof differs from the disclosure received from a Holder in its Selling Holder Questionnaire (as amended or supplemented). The Company shall not file a Registration Statement, any Prospectus or any amendments or supplements thereto in which it (i) characterizes any Holder as an underwriter, unless such characterization is consistent with written information provided by the Holder in the Selling Holder Questionnaire, (ii) excludes a particular Holder due to such Holder refusing to be named as an underwriter, or (iii) reduces the number of Registrable Securities being registered on behalf of a Holder without such Holder’s express written authorization. The Company shall also ensure that each Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein (in the case of prospectuses, in the light of the circumstances in which they were made) not misleading.

(b)The Company shall (i) prepare and file with the Commission such amendments, including post-effective amendments, to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement continuously effective as to the applicable Registrable Securities for its Effectiveness Period and prepare and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities, (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424, (iii) respond as promptly as reasonably possible to any comments received from the Commission with respect to each Registration Statement or any amendment thereto, and (iv) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the Registration Statement(s) and the disposition of all Registrable Securities covered by each Registration Statement.

(c)The Company shall notify the Holders as promptly as reasonably possible (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to a

4

Registration Statement is proposed to be filed; and (B) with respect to each Registration Statement or any post-effective amendment, when the same has become effective; (ii) of the issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and (iv) of the occurrence of any event or passage of time that makes the financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d)The Company shall use its commercially reasonable efforts to prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement, or the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible moment and to notify the Holders of the issuance of such order and the resolution thereof or its receipt of actual notice of the initiation or threat of any proceeding for such purpose.

(e)The Company shall promptly deliver to the Holders as many copies of each Prospectus or Prospectuses (including each form of prospectus) and each amendment or supplement thereto as the Holders may reasonably request. The Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

(f)Prior to any public offering of Registrable Securities, the Company shall (i) register or qualify such Registrable Securities for offer and sale under the securities or Blue Sky laws of all jurisdictions within the United States as any Holder may request, (ii) keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period and (iii) do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the Registration Statements; provided, however, in connection with any such registration or qualification, the Company shall not be required to (A) qualify to do business in any jurisdiction where the Company would not otherwise be required to qualify, (B) subject itself to general taxation in any such jurisdiction, (C) file a general consent to service of process in any jurisdiction, or (D) make any change to the Company’s articles of incorporation or bylaws.

(g)The Company shall cooperate with the Holders who hold Registrable Securities being offered and, to the extent applicable, facilitate the timely preparation and delivery of certificates or book-entry securities (not bearing any restrictive legend to the extent permitted by the ECCA, the Lock-Up Agreement, and the federal securities laws) representing the

5

Registrable Securities to be offered pursuant to a Registration Statement and enable such certificates or book-entry securities to be in such denominations or amounts, as the case may be, as the Holders may reasonably request and registered in such names as the Holders may request.

(h)As promptly as reasonably possible upon the occurrence of any event contemplated by Section 3(c)(iv), the Company shall prepare a supplement or amendment, including a post-effective amendment, to the affected Registration Statements or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(i)For so long as the Registrable Securities that have been registered under a Registration Statement remain Registrable Securities, the Company shall notify the Holders thereof in writing of the happening of any event, as promptly as reasonably practicable after becoming aware of such event, as a result of which the prospectus included in a Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (provided that in no event shall such notice contain any material, nonpublic information), and shall promptly prepare a supplement or amendment to such Registration Statement to correct such untrue statement or omission. The Company shall also notify the Holders of Registrable Securities that have been registered under a Registration Statement in writing as promptly as reasonably possible when a prospectus or any prospectus supplement or post-effective amendment has been filed, and when the Registration Statement or any post-effective amendment relating to such Registrable Securities has become effective.

(j)If any Holder is required under applicable securities laws to be described in the Registration Statement as an underwriter, at the reasonable request of such Holder, the Company shall furnish to such Holder, on the date of the effectiveness of the Registration Statement and thereafter from time to time on such dates as a Holder may reasonably request: (i) a letter, dated such date, from the Company’s independent certified public accountants in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the Holders, and (ii) an opinion, dated as of such date, of counsel representing the Company for purposes of such Registration Statement, in form, scope and substance reasonably acceptable to such counsel and as is customarily given in an underwritten public offering, addressed to the Holders.

(k)Other than the information regarding a Holder provided by such Holder to the Company for inclusion in a Registration Statement, the Company shall hold in confidence and not make any disclosure of information concerning a Holder provided to the Company unless: (i) disclosure of such information is necessary to comply with federal or state securities laws, (ii) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement, (iii) the release of such information is ordered pursuant to a subpoena or other final, non-appealable order from a court or governmental body of competent jurisdiction, or (iv) such information has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement. The Company agrees that it shall, upon

6

learning that disclosure of such information concerning a Holder is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt written notice to such Holder and allow such Holder, at the Holder’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information.

(l)The Company shall use its commercially reasonable efforts to cause all of the Registrable Securities covered by a Registration Statement to be listed on each national securities exchange on which securities of the same class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange. The Company shall pay all fees and expenses in connection with satisfying its obligation under this Section 3(l).

(m)If requested by a Holder and to the extent legally required for the Holder to offer and sell Registrable Securities, the Company shall as soon as practicable: (i) incorporate in a prospectus supplement or post-effective amendment such information as a Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to any Registration Statement if reasonably requested by a Holder holding any Registrable Securities.

4.Registration Expenses. All fees and expenses incident to the performance of or compliance with this Agreement by the Company shall be borne by the Company. Notwithstanding the foregoing, whether or not any Registrable Securities are sold pursuant to a Registration Statement, the Holder will reimburse the Company for up to $75,000 of its reasonable out-of-pocket fees and expenses promptly following the Effective Date. Such fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings required to be made with any Trading Market on which the Common Stock is then listed or quoted for trading, (B) with respect to filings with FINRA, and (C) in compliance with applicable state securities or Blue Sky laws), (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities and of printing prospectuses if the printing of prospectuses is reasonably requested by a Holder), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, and (vi) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated by this Agreement. In no event shall the Company be responsible for any broker or similar commissions incurred by any Holder or, except to the extent provided for in this Agreement, any legal fees or other cost of the Holders in connection with this Agreement.

5.Indemnification.

(a)Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Holder, the officers, directors,

7

agents, investment advisors, partners, members and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such form of prospectus or in any amendment or supplement thereto. The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of which the Company is aware in connection with the transactions contemplated by this Agreement.

(b)Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising solely out of or based solely upon any untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto, or arising solely out of or based solely upon any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading to the extent, but only to the extent that, such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such form of prospectus or in any amendment or supplement thereto. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c)Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its

8

obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses; (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party); provided, that, the Indemnifying Party shall pay for no more than two separate sets of counsel for all Indemnified Parties and such legal counsel shall be selected by the Holders who are named as parties in the same Proceeding. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

All fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within ten Business Days of written notice thereof to the Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder).

(d) Contribution. If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public policy or otherwise), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount

9

paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section 5(c), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 5(d), (i) no Person involved in the sale of Registrable Securities which Person is guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) in connection with such sale shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) no Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such Holder from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

The indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

6.Reports Under the Exchange Act. With a view to making available to the Holders the benefits of Rule 144 or any other similar rule or regulation of the SEC that may at any time permit the Holders to sell Registrable Securities of the Company to the public without registration, the Company agrees, for so long as Registrable Securities are outstanding and held by the Holders, to use its commercially reasonable efforts to:

(a)make and keep public information available, as those terms are understood, defined and required in Rule 144;

(b)file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and

(c)furnish to each Holder so long as such Holder owns Registrable Securities, promptly upon request, such information as may be reasonably and customarily requested to permit the Holders to sell such securities pursuant to Rule 144 without registration.

7.Assignment of Registration Rights. Neither this Agreement nor any of the rights, interests, or obligations hereunder shall be assignable by a Holder without the prior written consent of the Company. Further, the rights under this Agreement may be assignable by the Investor to any permitted transferee of all or any portion of such Investor’s Registrable Securities (which, for the avoidance of doubt, shall include Olympus Power LLC) if: (i) the Investor agrees in writing with the transferee or assignee to assign such rights and such transferee agrees to be bound by the terms of this Agreement, and a copy of such agreement is furnished to the Company within five (5) Business Days after such assignment; (ii) the Company is, within five (5) Business

10

Days after such transfer or assignment, furnished with written notice of (a) the name and address of such transferee or assignee, and (b) the securities with respect to which such registration rights are being transferred or assigned; (iii) immediately following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the Securities Act or applicable state securities laws; (iv) at or before the time the Company receives the written notice contemplated by clause (ii) of this sentence the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein; and (v) such transfer shall have been made in accordance with the applicable requirements of the Lock-Up Agreement, if then in effect, and the Second Amended and Restated Certificate of Incorporation of the Company and, if applicable, the  Third Amended and Restated Limited Liability Company Operating Agreement of Stronghold Digital Mining Holdings LLC.

8.Miscellaneous.

(a)Remedies. In the event of a breach by the Company or by a Holder, of any of their obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate.

(b)Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of Registrable Securities pursuant to the Registration Statement.

(c)Discontinued Disposition. Each Holder agrees that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in Section 3(c)(ii), (iii) or (iv), such Holder will forthwith discontinue disposition of Registrable Securities under the Registration Statement until such Holder's receipt of the copies of the supplemented Prospectus and/or amended Registration Statement or until it is advised in writing by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement. The Company may provide appropriate stop orders to enforce the provisions of this paragraph.

(d)Amendments and Waivers. Provisions of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the Holders. Any amendment or waiver effected in accordance with this Section 8(d) shall be binding upon each Investor and the Company. No such amendment shall be effective to the extent that it applies to less than all of the Holders. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of this Agreement unless the same consideration also is offered to all of the parties to this Agreement. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of certain Holders and that does not directly or indirectly affect the rights of other Holders may be given by Holders of at least a majority of the Registrable Securities to

11
