Item 1.01. Entry into a Material Definitive

Agreement

Merger Agreement

On June 23, 2026, HeartSciences

Inc., a Texas corporation (“HeartSciences” or “Parent”), Fortitude Mining Holdings, Inc., a Delaware

corporation (“Seller”), Fortitude Mining HoldCo, LLC, a Delaware limited liability company and a direct wholly-owned

subsidiary of Seller (“Fortitude”), and Cordis Acquisition, LLC, a Delaware limited liability company and a direct,

wholly-owned subsidiary of Parent (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger

Agreement”).

Fortitude is a Zcash mining

platform, applying a venture mining approach across high-growth digital assets with a primary focus on Zcash, a privacy-preserving, Proof-of-Work

asset built on Bitcoin’s core monetary principles. Fortitude is currently wholly-owned by Digital Currency Group, Inc. (“DCG”),

a company which invests in and operates companies focused on the cryptocurrency industry and decentralized technologies.

Transactions and Merger

Consideration

The Merger Agreement provides

that, subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, at the effective time of the Merger (the

“Effective Time”), Merger Sub will merge with and into Fortitude, with Fortitude surviving the merger (the “Merger”)

with HeartSciences thereby becoming the sole managing member of the surviving company (the “Surviving Company”).

The Merger Agreement provides

that, prior to the Effective Time, subject to the receipt of the Parent Stockholder Approvals (as defined below), HeartSciences will file

a new Amended and Restated Certificate of Formation with the Secretary of State of the State of Texas in accordance with the applicable

provisions of the Texas Business Organizations Code (the “Parent New Charter”) that, among other things, will establish

a new class of Parent’s common stock, designated as Class V common stock, $0.0001 par value per share (the “Parent Class

V Common Stock”), which will entitle the holder to one vote per share, and will have no economic rights. At Closing, the existing

common stock of Parent, will have a $0.0001 par value per share, and will then be designated as Class A common stock (the “Parent

Class A Common Stock”).

Prior to the closing of the

transactions contemplated by the Merger Agreement (the “Transactions”), including the Merger (the “Closing”),

Parent will (i) form a new Delaware limited liability company (“Parent Sub”) as a direct wholly-owned subsidiary of

Parent, (ii) contribute substantially all of its assets and liabilities to Parent Sub, and (iii) contribute 100% of the limited liability

company interests in Parent Sub to Merger Sub (the “Parent Contribution”). In addition, Seller will contribute all

of its assets and liabilities to Fortitude, including 100% of the limited liability company interests in each of its direct Subsidiaries

(as defined in the Merger Agreement) (the “Seller Contribution” and, together with the Parent Contribution, the “Contribution

Transactions”).

Immediately prior to the Effective

Time, Seller will contribute all of its voting interests in Fortitude (“Fortitude Voting Units”) and $2,000,000 of cash or Zcash cryptocurrency (“Zcash”) to Parent in exchange for a number of shares of Parent Class V Common Stock

equal to (A) the Closing Parent Common Stock Shares (as defined in the Merger Agreement) multiplied by (B) the Exchange Ratio (as calculated

pursuant to the terms of the Merger Agreement, subject to adjustment as provided therein), and a number of shares of Parent Class A Common

Stock equal to (x) $2,000,000 divided by (y) the Closing Parent Common Stock VWAP (as defined in the Merger Agreement) (collectively,

the “Contribution and Exchange”).

At the Effective Time, each

non-voting unit of Fortitude (each, a “Fortitude Non-Voting Unit”) issued and outstanding immediately prior to the

Effective Time will be converted into the right to receive a number of non-voting units of the Surviving Company (each, a “Surviving

Company Non-Voting Unit” and, collectively, “Surviving Company Units”) equal to (i) the Closing Parent Common

Stock Shares, multiplied by (ii) the Exchange Ratio (collectively, the “Merger Consideration”).

Each unit of Merger Sub issued

and outstanding immediately prior to the Effective Time will be converted into a number of Surviving Company Non-Voting Units equal to

the number of shares of Parent’s common stock outstanding as of immediately prior to the Effective Time, as set forth in the Amended

and Restated Limited Liability Company Agreement of the Surviving Company (the “A&R LLC Agreement”).

In connection with the Transactions,

each share of Parent’s Series C Convertible Preferred Stock, $0.001 par value per share (the “Parent Series C Preferred

Stock”), issued and outstanding immediately prior to the Effective Time will be converted into a number of shares of Parent

Class A Common Stock as determined by dividing the then-effective Series C Original Issue Price by the then-effective Series C Conversion

Price (each as defined in the Certificate of Designations, Number, Voting Power, Preferences and Rights of Parent Series C Preferred Stock)

(the “Mandatory Conversion”). Immediately prior to the Effective Time, each share of Parent’s Series D Convertible

Preferred Stock, $0.001 par value per share (the “Parent Series D Preferred Stock”), issued and outstanding immediately

prior to the Effective Time will be converted into one fully paid and nonassessable share of Parent Class A Common Stock in accordance

with the Certificate of Designations, Number, Voting Power, Preferences and Rights of Parent Series D Preferred Stock (the “Series

D Forced Conversion”).

Immediately prior to the Effective

Time, HeartSciences will cause its transfer agent to issue to Seller shares of Parent Class V Common Stock and Parent Class A Common Stock,

each as described above. Immediately after the Effective Time, Parent will contribute all of the cash or Zcash, as the case may be, received

in the Contribution and Exchange to the Surviving Company in exchange for additional Surviving Company Non-Voting Units.

Following the Closing, and

subject to any Pre-Closing PIPE Investment (as defined in the Merger Agreement) or other permitted equity issuances by Parent prior to

Closing, (i) the aggregate number of shares of Parent Class V Common Stock and Parent Class A Common Stock issued to the equityholders

of Fortitude pursuant to the Merger Agreement are expected to represent approximately 95.0% of the outstanding equity interests of Parent,

(ii) Parent equityholders as of immediately prior to Closing are expected to own approximately 5.0% of the outstanding equity interests

of Parent, in the aggregate, in the form of Parent Class A Common Stock, (iii) the equityholders of Fortitude will hold a number of Surviving

Company Non-Voting Units which are expected to represent approximately 95.0% of the outstanding Surviving Company Non-Voting Units in

the Surviving Company, and (iv) Parent will be the sole managing member of the Surviving Company and will hold all of the voting units

of the Surviving Company and a number of Surviving Company Non-Voting Units which are expected to represent approximately 5.0% of the

outstanding Surviving Company Non-Voting Units in the Surviving Company.

The Closing is expected to

take place during the second half of 2026, subject to the satisfaction of the closing conditions, including the requirement to obtain

Stockholder Approvals.

Governance of the Surviving

Company

Following the Merger, the

limited liability company agreement of Fortitude will be amended and restated in its entirety in the form of the A&R LLC Agreement

to, among other things, permit the issuance of the Surviving Company Units, admit Parent as the sole managing member of the Surviving

Company, and establish the ownership of the Surviving Company Units by Seller and Parent.

In connection with the Closing,

(i) Parent will take all necessary action to increase the size of its Board of Directors (the “Board”) as directed

by Seller and appoint the individuals determined by Seller prior to the Closing to the Board effective as of the Effective Time (collectively,

the “Board Change”), (ii) it is expected that Andrew Simpson and David Wells, each a current member of the Board, shall

remain on the Board after the Closing, and (iii) Andrea Childs will be named Chief Executive Officer and Erik Ellingson will be named

Chief Financial Officer of Parent, respectively (collectively, the “Officers Change”).

Representations, Warranties

and Covenants

The Merger Agreement contains

customary representations, warranties and covenants of HeartSciences and Seller, including covenants relating to the conduct of the business

of both HeartSciences and Seller from the date of signing the Merger Agreement through the Closing, obtaining the requisite approval of

the stockholders of HeartSciences and Seller (as sole member of Fortitude), maintaining the listing of Parent Class A Common Stock on

the Nasdaq Capital Market (“Nasdaq”) and applying for the continued listing of HeartSciences after the closing of the

Merger on Nasdaq.

The Merger Agreement provides

that the parties will use their respective reasonable best efforts to take all actions reasonably necessary, proper or advisable to consummate

and make effective, as promptly as reasonably practicable, the Transactions.

Under the terms of the Merger

Agreement, HeartSciences has also agreed to certain restrictions on its ability to solicit Parent Acquisition Proposals (as defined in

the Merger Agreement) from third parties, to provide non-public information to third parties and to engage in discussions with third parties

regarding Parent Acquisition Proposals, subject to customary exceptions.

In connection with the Transactions,

HeartSciences will prepare and file with the U.S. Securities and Exchange Commission (the “SEC”) a proxy statement

(together with any amendments or supplements thereto, the “Proxy Statement”) relating to a special meeting of HeartSciences’

stockholders (the “Parent Stockholder Meeting”), and will seek the approval of HeartSciences’ stockholders with

respect to certain actions, including the following (collectively, the “Parent Stockholder Proposals”):

(i) approval pursuant to Listing Rule 5635 of Nasdaq of (x) the

issuance of shares of Parent Class V Common Stock as contemplated by the Merger Agreement and any issuance of shares of Parent Class

A Common Stock pursuant to the Contribution and Exchange or a Pre-Closing PIPE Investment and (y) the change of control of HeartSciences

resulting from the Transactions;

(ii) approval of the Merger Agreement and the Transactions (including the Merger) pursuant to the Texas Business

Organizations Code (the “TBOC”);

(iii) adoption of the Parent New Charter; and

(iv) approval of an amendment and restatement of HeartSciences’

equity incentive plan.

The Board has agreed to recommend

the approval of the Parent Stockholder Proposals to HeartSciences’ stockholders and to solicit proxies in support of each such approval

the Parent Stockholder Meeting. HeartSciences will hold a special meeting of shareholders to obtain Parent Stockholder Proposals as soon

as practicable after the filing of the definitive Proxy Statement.

Under the Merger Agreement,

HeartSciences has agreed that neither the Board nor any Board committee will fail to make, withdraw or qualify, amend or modify, in any

manner adverse to Seller, the Board’s recommendation in favor of the Parent Stockholder Proposals or otherwise make a Parent Adverse

Recommendation Change (as defined in the Merger Agreement). Nonetheless, the Merger Agreement does contain a limited contractual ability

for the Board, in accordance with its fiduciary duties to HeartSciences’ stockholders, to make a Parent Adverse Recommendation Change,

(i) upon receipt of a superior third-party acquisition proposal (a “Parent Superior Proposal”), subject to certain

terms and conditions, including providing Seller with the required notice, or (ii) upon the occurrence of a Parent Intervening Event (as

defined in the Merger Agreement).

Under the Merger Agreement,

HeartSciences has agreed to maintain the indemnification rights (including with respect to advancement of expenses) of the officers and

directors of HeartSciences and Seller as in effect immediately prior to the Closing and maintain, for a period of at least six years following

the Closing, directors’ and officers’ liability insurance with respect to claims arising from facts or events that occurred

at or before the Closing.

Conditions to Closing

The Closing is subject to

the satisfaction or waiver of customary conditions, including, among other things, (i) receipt of the required approval of the Parent

Stockholder Proposals by the stockholders of HeartSciences and the consent of Seller (as sole member of Fortitude) (the “Seller

Consent”), (ii) the expiration or termination of any applicable waiting period under the HSR Act, (iii) the accuracy of the

representations and warranties of the parties made in the Merger Agreement, subject to customary materiality qualifiers, (iv) compliance

by the parties with their respective covenants and agreements under the Merger Agreement, (v) the approval for continued listing of Parent

Class A Common Stock on Nasdaq after the Closing (including shares issued in connection with the Merger and any Pre-Closing PIPE Investment),

(vi) the absence of any governmental order prohibiting the Merger and (vii) the absence of a material adverse effect with respect to the

other party.

In addition, Seller’s

obligation to complete the Closing is also subject to further conditions, including (i) Parent’s common stock not having been delisted

from Nasdaq, (ii) the absence of any event that would reasonably be expected to result in HeartSciences being ineligible to register securities

using a Registration Statement on Form S-3 and (iii) conversion of Parent Series C Preferred Stock and Parent Series D Preferred Stock

into Parent Class A Common Stock.

Termination and Fees

The parties may terminate

the Merger Agreement by mutual written agreement of HeartSciences and Seller. Either party may terminate the Merger Agreement (i) if any

governmental order permanently restraining, enjoining or otherwise prohibiting the Merger becomes final and non-appealable, (ii) if the

Parent Stockholder Approvals are not obtained at the Parent Stockholder Meeting or any adjournment or postponement thereof at which the

vote was taken or (iii) if the Merger is not consummated on or before the date that is seven (7) months after the date of the Merger Agreement

(the “End Date”).

Seller may also terminate

the Merger Agreement if (i) the Board makes a Parent Adverse Recommendation Change, (ii) a breach of any representation or warranty or

failure to perform any covenant on the part of HeartSciences has occurred that would cause a closing condition not to be satisfied and

has not been cured within 20 days following written notice, (iii) Parent’s common stock is delisted from Nasdaq, or (iv) HeartSciences

becomes ineligible to register securities using a Registration Statement on Form S-3.

HeartSciences may also terminate

the Merger Agreement if (i) the Seller Consent or the Seller Stockholder Consent (as defined in the Merger Agreement) has not been obtained,

or (ii) a breach of any representation or warranty or failure to perform any covenant on the part of Seller has occurred that would cause

a closing condition not to be satisfied and has not been cured within twenty (20) days following written notice.

In the event that (i) Seller

terminates the Merger Agreement following a Parent Adverse Recommendation Change, or HeartSciences or Seller terminates following a failure

to obtain the Parent Stockholder Approvals at a time when the Merger Agreement was terminable by Seller following a Parent Adverse Recommendation

Change, or (ii) under certain circumstances, a Parent Acquisition Proposal is publicly disclosed prior to the Parent Stockholder Meeting,

and the Merger Agreement is terminated for failure to obtain the requisite approval of the HeartSciences Stockholder Proposals and, prior

to the first anniversary of the termination of the Merger Agreement, HeartSciences enters into a definitive agreement relating to a Parent

Acquisition Proposal (that is subsequently consummated) or consummates a transaction relating to a Parent Acquisition Proposal, then,

in each case, HeartSciences will be required to pay Seller a termination fee of $2,500,000 (the “Parent Termination Fee”),

plus Seller’s reasonable out-of-pocket fees and expenses incurred in connection with the Merger Agreement and the Transactions.

In addition, if HeartSciences terminates the Merger Agreement because the Seller Consent has not been obtained, Seller will be required

to pay HeartSciences a termination fee of $6,000,000 (the “Fortitude Termination Fee”), plus HeartSciences’ reasonable

out-of-pocket fees and expenses incurred in connection with the Merger Agreement and the Transactions.

of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement,

which is filed as Exhibit 2.1 to this Current Report on Form 8-K (this “Current Report”) and is incorporated herein

by reference.

The Merger Agreement is incorporated

may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the

purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and

may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors

are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any

descriptions thereof as characterizations of the actual state of facts or condition of the parties thereto or any of their respective

subsidiaries or affiliates or their respective businesses. Moreover, information concerning the subject matter of representations and

warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in HeartSciences’

or any other person’s public disclosures. Accordingly, the Merger Agreement is incorporated herein by reference only to provide

investors with information regarding the terms of the Merger Agreement and should be read in conjunction with the disclosures in Parent’s

periodic reports and other filings with the SEC.

Voting and Support Agreements

In connection with the execution

and delivery of the Merger Agreement, and as a condition to the willingness of Seller to enter into the Merger Agreement, certain of the

stockholders of HeartSciences, including certain holders of more than 50% of the outstanding shares of Parent Series C Preferred Stock

Pursuant to the Support Agreements,

the signing stockholders have agreed, among other things, to vote their respective shares of Parent’s common stock and Parent Series

C Preferred Stock (i) in favor of the Parent Stockholder Approvals, (ii) in favor of any proposal to adjourn or postpone the Parent Stockholder

Meeting, if necessary, to permit further solicitation of proxies, and (iii) against any action, agreement or transaction that is intended

to, or would reasonably be expected to, impede, interfere with, delay, postpone or discourage the transactions contemplated by the Merger

Agreement. In addition, the Support Agreements provide that all of the outstanding shares of Parent Series C Preferred Stock will be converted

into shares of Parent Class A Common Stock in accordance with the terms of the Merger Agreement.

The foregoing summary does

of control (as defined under the Tax Receivable Agreement, which includes certain mergers, asset sales and other forms of business combinations

and certain changes to the composition of the Board after the Closing) with respect to any taxable periods ending on or after such early

termination event, in each case, as a result of, among other things, (i) Basis Adjustments (as defined in the Tax Receivable Agreement)

-3-

to the Surviving Company in exchange for additional Surviving Company Non-Voting Units.

Section 1.02. Contribution

and Exchange.

(a) Immediately

prior to the Effective Time, (i) Seller shall contribute all of its Fortitude Voting Units to Parent in exchange for the right to receive

Trust Company, LLC, to issue to Seller a number of shares of Parent Class V Common Stock equal to the Fortitude Voting Unit Contribution

Consideration (such contribution and issuance, the “Fortitude Voting Unit Contribution”). In the event that the Effective

Time does not occur for any reason, the issuance of the shares of Parent Class V Common Stock shall be deemed void ab initio, and

such shares shall be automatically canceled and retired and shall cease to exist without any action on the part of any party, and the

Fortitude Voting Units shall be deemed to have been retained by Seller as though such exchange had never occurred.

(b) Immediately

occurred.

(c)

No Fractional Shares. Notwithstanding anything in this Agreement to the contrary, no fractional shares of Parent Class

V Common Stock or Parent Common Stock shall be issued to Seller pursuant to this Section 1.02. If, in the absence of this Section

otherwise would be so paid is less than five-tenths (0.5) of a share of Parent Class V Common Stock or Parent Common Stock, as applicable,

and (y) rounded up to the nearest whole number in the event that the fractional share that otherwise would be so paid is greater than

(as may be updated by Seller prior to Closing upon written notice to Parent), subject to compliance with all applicable Nasdaq requirements;

provided that such resignations shall be null and void if this Agreement is terminated prior to the Effective Time for any reason

or no reason.

Section 1.08. Non-Assignable

Assets. In connection with the Parent Contribution, if the assignment or transfer of any asset, or any claim, right or

benefit arising thereunder or resulting therefrom, without the consent of a Third Party, would constitute a breach or other

contravention of the rights of such Third Party, would be ineffective with respect to any party to an agreement concerning such

asset, claim, right or benefit, or, upon assignment or transfer, would in any way adversely affect the rights of Parent or, upon

transfer, Parent Sub, Merger Sub or the Surviving Company (each, a “Non-Assignable Right”), then Parent shall, at

Parent’s sole cost and expense, use its commercially reasonable efforts to obtain such consent after the execution of this

Agreement until the earlier of (a) the date that such consent is obtained; or (b) the date that is six (6) months following the

Closing Date, and Seller shall use its commercially reasonable efforts to assist and cooperate with Parent in connection therewith.

If any such consent cannot be obtained prior to the Closing, then, notwithstanding anything to the contrary in this Agreement or any

Ancillary Agreement, (i) this Agreement and the related instruments of transfer shall not constitute an assignment or transfer of

the applicable Non-Assignable Right, and Parent shall use its commercially reasonable efforts to obtain such consent as soon as

possible after the Closing (subject to the preceding sentence), and Parent shall use its commercially reasonable efforts to obtain

for the Surviving Company substantially all of the practical benefit of such Non-Assignable Right, including by (1) entering into

appropriate and reasonable alternative arrangements; (2) subject to the consent and control of the Surviving Company, enforcement,

at the cost and for the account of the Surviving Company, of any and all rights of Parent against the other party thereto arising

out of the breach or cancellation thereof by such other party or otherwise. Notwithstanding anything to the contrary set forth

herein, none of Parent, Seller or any of their respective Affiliates shall be required to make any payments to any Third Party,

commence any litigation or offer or grant any accommodation (financial or otherwise) to any Third Party in connection with the

performance of its or their respective Affiliates’ obligations under this Section 1.08. For all applicable Tax

purposes, the beneficial ownership of the assets described in this Section 1.08 shall be deemed transferred to the Surviving

Company in a transaction governed by Section 721 of the Code as provided in the Intended Tax Treatment. For the avoidance of doubt,

so long as Parent has satisfied its obligations under this Section 1.08, Parent’s inability to contribute to Parent Sub

or Merger Sub any Non-Assignable Right shall not be construed in any way as a breach of any of the obligations, covenants,

agreements, representations or warranties of Parent or Merger Sub under this Agreement.

multiplied by (ii) the Exchange Ratio (collectively, the “Merger Consideration”). The Merger Consideration issued

(b) Conversion

of Merger Sub Units. Each unit of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into

the number of Surviving Company Non-Voting Units set forth in the A&R LLC Agreement.

Section 2.02. Conversion

of Parent Series C Preferred Stock. If there is a Pre-Closing PIPE Investment, then immediately after the consummation of

such Pre-Closing PIPE Investment, or if there is no Pre-Closing PIPE Investment, then immediately after the Effective Time, each

share of Parent Series C Preferred Stock issued and outstanding immediately prior to the Effective Time shall be converted into such

number of fully paid and nonassessable shares of Parent Common Stock as determined by dividing the then-effective Series C Original

Issue Price by the then-effective Series C Conversion Price (each as defined in the Series C Certificate of Designations).

Section 2.03. Parent

Series D Preferred Stock. Immediately prior to the Effective Time, each share of Parent Series D Preferred Stock issued

Section 2.04. Withholding

Rights. Parent and the Surviving Company, as the case may be, (i) will deduct and withhold from the consideration

otherwise required to be distributed pursuant to this Agreement such amounts as may be required to be deducted and withheld under

the Code or any provision of state, local or non-U.S. Tax Law and (ii) shall be entitled to request and be provided any necessary

Tax forms, including IRS Form W-9 or the appropriate version of IRS Form W-8, as applicable, or any similar information. Any amounts

withheld and remitted to the applicable Taxing Authority in accordance with Applicable Law will be treated for all purposes of this

Agreement as having been distributed to the Persons otherwise entitled hereto. If Parent or the Surviving Company intends to make

any deduction or withholding from the Merger Consideration, then Parent will, not less than ten (10) Business Days prior to the

Closing Date, provide Seller with written notice of such intent, setting forth in reasonable detail the basis for such deduction or

withholding, and the Parties will cooperate on a reasonable basis to reduce or eliminate such deduction or withholding.

Section 2.05. Dissenting

Shares.

(a) Notwithstanding

any provision of this Agreement to the contrary, other than as provided in this Section 2.05, any shares of Parent Series C Preferred

Stock or Parent Series D Preferred Stock that are issued and outstanding immediately prior to the Effective Time and are held by a holder

of such shares who has duly and validly demanded appraisal of such shares in connection with the Merger in accordance with Chapter 10,

Subchapter H of the TBOC and as of the Effective Time, has not effectively withdrawn or lost such appraisal rights (through failure to

perfect or otherwise) (a “Dissenting Share”) shall not be converted into or represent the right to receive any portion

of the consideration to be paid pursuant to Section 2.01 but instead shall be converted into the right to receive only such consideration

as may be determined to be due with respect to such Dissenting Shares under Chapter 10, Subchapter H of the TBOC. From and after the Effective

Time, the Dissenting Shares shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and

a holder of Dissenting Shares shall not be entitled to exercise any of the voting rights or other rights of a holder of Parent Series

C Preferred Stock or Parent Series D Preferred Stock following the Closing.

(b) If

any holder of a Dissenting Share who has duly and validly demanded appraisal of such shares in connection with the Merger in accordance

with Chapter 10, Subchapter H of the TBOC effectively withdraws or loses such appraisal rights (through failure to perfect or otherwise),

then such shares shall no longer be Dissenting Shares and, as of the later of the Effective Time and the occurrence of such withdrawal

or loss, such shares shall automatically be converted into the right to receive, without interest, the consideration to be paid pursuant

to Section 2.01 with respect to such shares pursuant to and in accordance with this Agreement.

shall give Seller reasonably prompt written notice of the receipt of any written notice of any demand for appraisal for any Dissenting

Share, withdrawals of such demands or any intent to demand or withdraw the foregoing, and any other instruments served pursuant to Applicable

Law and received by Parent that relate to any such demand for appraisal (each, an “Appraisal Demand”), and Seller shall

have the right to participate in all negotiations and proceedings with respect to any Appraisal Demand or any threatened Appraisal Demand,

including those that take place prior to the Effective Time. Parent shall not voluntarily make any payment with respect to, or settle

or offer to settle, any Appraisal Demand prior to the Effective Time, or waive any failure to timely deliver a written demand for appraisal

or the taking of any other action by such holder of any Dissenting Share as may be necessary to perfect appraisal rights under Applicable

Law, without the prior written approval of Seller.

Fortitude Permit is pending or, to the knowledge of Seller or Fortitude, threatened, except where the failure to be in full force

provision of, or committed or failed to perform any act that (with or without notice, lapse of time or both) would constitute a default

under any provision of, and as of the date of this Agreement neither Seller nor any of its Subsidiaries has received written notice that

it has violated or defaulted under, any Fortitude Material Contract, except for those violations and defaults (or potential defaults)

that would not reasonably be expected to have, individually or in the aggregate, a Fortitude Material Adverse Effect.

respect to a Tax assessment or deficiency which waiver or extension is still in effect, and no written request for any such waiver or

Parent and each of its Subsidiaries is insured with reputable insurance carriers against such risks and in such amounts as are usually

Property”), together with the address of each such Parent Leased Real Property and (ii) all leases, subleases or licenses or

a “Parent Real Property Lease”). Parent has delivered or made available to Fortitude complete and accurate copies of

each Parent Real Property Lease described in Section 4.24(b) of the Parent Disclosure Letter, and no Parent Real Property Lease

has been modified in any material respect or terminated, except to the extent that such modifications or terminations are disclosed by

the copies delivered or made available to Seller. Except as would not reasonably be expected, individually or in the aggregate, to be

material to Parent and its Subsidiaries, taken as a whole, (a) Parent and each of its Subsidiaries holds a valid and existing leasehold,

subleasehold, license or other similar interest under each Parent Real Property Lease, free and clear of all Liens other than Permitted

Liens and (b) each Parent Real Property Lease is a valid and binding agreement, enforceable against Parent or one of its Subsidiaries,

or otherwise occupied in the operation of the businesses of Parent and its Subsidiaries as currently conducted. Parent and its Subsidiaries

have not assigned or sublet their interests under, nor granted any security interest in, any Parent Leased Real Property and no Person

other than Parent or its Subsidiaries, as applicable, has the right to use or occupy any of the Parent Leased Real Property. Neither Parent

nor any of its Subsidiaries is subject to any waiver or forbearance or any deferred, abated or reduced rent with respect to any Parent

Real Property Lease.

Parent nor any of its Subsidiaries nor, to the knowledge of Parent, any other party to any Parent Real Property Lease is in default or

breach under the terms of any such Parent Real Property Lease, except where such default or breach would not reasonably be expected, individually

or in the aggregate, to be material to Parent and its Subsidiaries, taken as a whole. No event has occurred that, with notice or lapse

of time or both, would constitute a default or breach under any Parent Real Property Lease, and no portion of any security deposit has

been applied under any Parent Real Property Lease, except as would not reasonably be expected, individually or in the aggregate, to be

material to Parent and its Subsidiaries, taken as a whole. To the knowledge of Parent, as of the date of this Agreement there are no material

disputes with respect to any Parent Real Property Lease. Neither Parent nor any of its Subsidiaries have received any written notice of,

nor to the knowledge of Parent does there exist, any pending or threatened condemnation or similar proceedings, or any sale or other disposition

of any Parent Leased Real Property or any part thereof in lieu of condemnation.

Section

4.27. Opinion of Independent Valuation Advisor. Parent has received the written opinion of Houlihan Capital, LLC, an independent

valuation advisor to Parent, to the effect that, as of the date of such opinion and subject to the assumptions, qualifications, limitations

and other matters considered in connection with the preparation of such opinion, the aggregate consideration to be paid in the Transactions

is fair to the shareholders of Parent from a financial point of view. A complete and executed copy of the opinion of Houlihan Capital,

LLC described in the immediately preceding sentence has been or will be delivered to Seller promptly following receipt thereof by Parent.

Section 4.28. Brokers.

There is no investment banker, broker, finder or other intermediary that has been retained by or is authorized to act on behalf of Parent

or any of its Subsidiaries who might be entitled to any fee or commission from Parent or any of its Subsidiaries in connection with the

Transactions.

Section 4.29. No

Ownership of Fortitude Units. Neither Parent nor any of its Subsidiaries (a) beneficially owns, directly or indirectly, any

Fortitude Units or other securities convertible into, exchangeable for or exercisable for Fortitude Units or (b) has any rights to acquire

any Fortitude Units. There are no voting trusts or other agreements or understandings to which Parent or any of its Subsidiaries is a

party with respect to the voting of Fortitude Units. Neither Parent nor any of its Subsidiaries is an “interested stockholder”

(as defined in Section 203 of the DGCL) of Fortitude.

to this Article IV) (but without limiting any representations and warranties in any Ancillary Agreement), neither Parent nor any

other Person makes or has made any representation or warranty, expressed or implied, at law or in equity, with respect to or on behalf

stockholders or Representatives. Parent acknowledges and agrees that, except for the representations and warranties made by Seller in

Article III (as qualified by the applicable items disclosed in the Seller Disclosure Letter in accordance with Section 10.17

and the introduction to Article III) (but without limiting any representations and warranties in any Ancillary Agreement), neither

Seller nor any other Person is making or has made any representations or warranty, expressed or implied, at law or in equity, with respect

to or on behalf of Seller or its Subsidiaries, or the accuracy or completeness of any information regarding Seller or its Subsidiaries

against any Parent Acquisition Proposal or (II) fail to publicly reaffirm the Parent Board Recommendation, in the case of the foregoing

clauses (I) and (II), within three (3) Business Days after Seller so requests in writing following the public disclosure of any Parent

Acquisition Proposal, or (F) subject to Section 6.02(c), fail to recommend against any Parent Acquisition Proposal that is a tender

offer or exchange offer subject to Regulation 14D promulgated under the Exchange Act (including, for these purposes, by taking no position

with respect to the acceptance of such tender offer or exchange offer by the stockholders of Parent) within ten (10) Business Days after

the commencement of such tender offer or exchange (any of the foregoing, a “Parent Adverse Recommendation Change”)

or (y) take any action to make any “moratorium,” “business combination with an affiliated shareholder,” “affiliated

shareholder’s share acquisition,” “affiliated shareholder” or “business combination” or other similar

anti-takeover Laws and regulations of the State of Texas, including Section 21.606 of the TBOC, inapplicable to any Third Party or any

Parent Acquisition Proposal.

the foregoing, if at any time prior to the receipt of the Parent Stockholder Approvals (the “Parent Approval Time”)

(and in no event after the Parent Approval Time), the Board of Directors of Parent receives a bona fide written Parent Acquisition Proposal

made after the date of this Agreement that did not result from any breach of this Section 6.02, the Board of Directors of Parent

(or duly appointed committee thereof) may, if the Board of Directors of Parent determines in good faith, after consultation with Parent’s

financial advisor, if any, and outside legal counsel, and based on the information then available to it, that (x) such Parent Acquisition

Proposal either constitutes a Parent Superior Proposal or would reasonably be expected to result in a Parent Superior Proposal and (y)

the failure to take such actions would be inconsistent with its fiduciary duties under Applicable Law, then Parent and its Representatives

may, subject to compliance with this Section 6.02(c), Section 6.02(d) and Section 6.02(f), (i) engage in negotiations

or discussions with such Third Party that has made after the date of this Agreement a Parent Acquisition Proposal; and (ii) furnish to

such Third Party and its Representatives non-public information relating to Parent or any of its Subsidiaries pursuant to a confidentiality

agreement with terms no less favorable to Parent than those contained in the Confidentiality Agreement (it being understood that such

confidentiality agreement need not include any standstill terms or similar obligations and shall not provide such Person with any exclusive

right to negotiate with Parent) (an “Acceptable Confidentiality Agreement”) (a copy of which shall be provided substantially

concurrently or as promptly as practicable (but in any event not more than twenty-four (24) hours) following its execution to Seller for

informational purposes); provided that all such non-public information (to the extent that such information has not been previously

provided or made available to Seller) is provided or made available to Seller, as the case may be, substantially concurrently or as promptly

as practicable (but in any event not more than twenty-four (24) hours) following the time it is provided or made available to such Third

Party. Nothing contained herein shall prevent the Board of Directors of Parent from (x) complying with Rule 14e-2(a) promulgated under

the Exchange Act with regard to a Parent Acquisition Proposal or making a statement contemplated by Item 1012(a) of Regulation M-A or

Rule 14d-9 promulgated under the Exchange Act or from making any legally required disclosure to stockholders with regard to the Transactions

(each of which shall not constitute a Parent Adverse Recommendation Change); (y) making any required disclosure to Parent’s stockholders

if the Board of Directors of Parent determines in good faith, after consultation with its outside legal counsel, that the failure to take

such action would be inconsistent with its fiduciary duties under Applicable Law; or (z) issuing a “stop, look and listen”

disclosure or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act; provided that (I) if any

such compliance, statement or disclosure does not reaffirm the Parent Board Recommendation, it shall be deemed a Parent Adverse Recommendation

Change, and (II) any Parent Adverse Recommendation Change involving or relating to a Parent Acquisition Proposal may only be made in accordance

with the provisions of this Section 6.02(c), Section 6.02(d) and Section 6.02(f).

-57-

(d) In

addition to the requirements set forth in Section 6.02(c) and subject to compliance with Section 6.02(e) and Section

6.02(f), the Board of Directors of Parent shall not take any of the actions referred to in clauses (i) and (ii) of Section

6.02(c) unless Parent shall have first delivered to Seller written notice advising Seller that Parent intends to take any such action.

In addition, Parent shall notify Seller promptly (but in no event later than twenty-four (24) hours) after receipt by Parent (or any of

its Representatives) of any Parent Acquisition Proposal, indication or request for information (including material modifications thereto)

relating to Parent or any of its Subsidiaries or for access to the business, officers, directors, employees, properties, assets, books

or records of Parent or any of its Subsidiaries by any Third Party that, to the knowledge of Parent or any member of the Board of Directors

of Parent, is considering making or has made a Parent Acquisition Proposal, which notice shall be provided in writing and shall (i) identify

the relevant Third Party, (ii) to the extent known, describe the material terms and conditions of, any such Parent Acquisition Proposal,

indication or request (including any material changes thereto) and (iii) if applicable, include an unredacted copy of such Parent Acquisition

Proposal, indication or request (including any related documents and correspondence).

(e) Notwithstanding

anything in this Agreement to the contrary, at any time prior to the Parent Approval Time (and in no event after the Parent Approval Time),

the Board of Directors of Parent may effect a Parent Adverse Recommendation Change in response to a Parent Intervening Event, but only

if, prior to taking such action: (i) the Board of Directors of Parent determines in good faith, after consultation with Parent’s

outside legal counsel, that the failure to take such action would be inconsistent with its fiduciary duties under Applicable Law, (ii)

Parent shall (A) promptly notify Seller in writing of its intention to take such action at least four (4) Business Days before taking

such action and (B) if requested by Seller, negotiate in good faith with Seller for four (4) Business Days following such notice regarding

revisions, if any, to the terms of this Agreement proposed by Seller (or any other proposal Seller may make) so that such Parent Adverse

Recommendation Change is no longer necessary and (iii) after the four (4) Business Day period described in the foregoing clause (B), the

Board of Directors of Parent determines in good faith, taking into account any proposal by Seller to amend the terms of this Agreement

(or any other proposal made by Seller), after consultation with its outside legal counsel and financial advisor, that the failure to take

such action would be inconsistent with its fiduciary duties under Applicable Law.

(f) Without

limiting Section 6.02(a), Section 6.02(c) or Section 6.02(d), if Parent shall have received a bona fide written Parent

Acquisition Proposal that was made or renewed after the date of this Agreement (and has not been withdrawn) that did not result or arise

out of material breach of this Agreement, and the Board of Directors of Parent shall have determined in good faith, after consultation

with Parent’s financial advisors, if any, and outside legal counsel, that such Parent Acquisition Proposal is a Parent Superior

Proposal, then the Board of Directors of Parent may make a Parent Adverse Recommendation Change, but only if: (i) the Board of Directors

of Parent determines in good faith, after consultation with Parent’s outside legal counsel, that the failure to take such action

would be inconsistent with the fiduciary duties of the Board of Directors to Parent’s stockholders under Applicable Law; (ii) Parent

promptly notifies Seller, in writing at least four (4) Business Days before taking such action, that Parent intends to take such action,

which notice attaches in unredacted form the most current version of any proposed agreement(s), the identity of the offeror and a copy

of any financing commitments (which may be redacted for fee information and other customary matters); (iii) if requested by Seller, during

such four (4) Business Day period, Parent and its Representatives have discussed and negotiated in good faith with Seller regarding any

proposal by Seller to amend the terms of this Agreement (or any other proposal Seller may make) so that such Parent Acquisition Proposal

would cease to constitute a Parent Superior Proposal; and (iv) after such four (4) Business Day period, the Board of Directors of Parent

determines in good faith, after consultation with its outside legal counsel and financial advisor, taking into account any proposal by

Seller to amend the terms of this Agreement (or any other proposal made by Seller), that such Parent Acquisition Proposal continues to

constitute a Parent Superior Proposal (it being understood and agreed that in the event of any amendment to the financial terms or other

material terms of any such Parent Superior Proposal (including any change to the exchange ratio or merger consideration), a new written

notification from Parent consistent with that described in clause (ii) of this Section 6.02(f) shall be required and a new

notice period under clause (ii) of this Section 6.02(f) shall commence, during which notice period Parent shall be required

to comply with the requirements of this Section 6.02(f) anew, except that such new notice period shall be for three (3) Business

Days (as opposed to four (4) Business Days)).

-58-

(g) Parent

shall, and shall cause its Subsidiaries and controlled Affiliates, and shall direct its other Representatives, to (i) immediately cease

and cause to be terminated any and all existing activities, discussions or negotiations, if any, with any Third Party conducted prior

to the date of this Agreement with respect to any Parent Acquisition Proposal or which would reasonably be expected to lead to a Parent

Acquisition Proposal and instruct any such Third Party (or its agents or advisors) in possession of confidential, non-public information

or documents or material incorporating non-public information about Parent that was furnished by or on behalf of Parent to return or destroy

all such information and (ii) other than with respect to Seller and its Representatives, terminate access to any virtual data room established

for or used in connection with any actual or potential Parent Acquisition Proposal.

(h) Notwithstanding

any Parent Adverse Recommendation Change, the making of any Parent Acquisition Proposal or anything in this Agreement to the contrary,

until the termination of this Agreement (i) in no event may Parent or any of its Subsidiaries enter into any legally binding merger agreement,

letter of intent, agreement in principle, acquisition agreement, joint venture agreement, partnership agreement or other similar agreement

relating to or constituting a Parent Acquisition Proposal (other than an Acceptable Confidentiality Agreement), and (ii) Parent shall

otherwise remain subject to all of its obligations under this Agreement, including, for the avoidance of doubt, the obligation to hold

the Parent Stockholder Meeting.

(i) For

purposes of this Agreement:

(i) “Parent

Superior Proposal” means any bona fide, written Parent Acquisition Proposal (other than a Parent Acquisition Proposal that has

resulted from a violation of this Section 6.02) (with all references to “15%” in the definition of Parent Acquisition

Proposal being deemed to be references to “50%”) on terms that the Board of Directors of Parent determines in good faith,

after consultation with its financial advisors, if any, and outside legal counsel, and taking into account all the terms and conditions

of the Parent Acquisition Proposal (including the identity of the Person making the Parent Acquisition Proposal and the expected timing

and likelihood of consummation, any governmental or other approval requirements (including divestitures and entry into other commitments

and limitations), conditions to consummation and availability of necessary financing), would result in a transaction (A) that, if consummated,

is more favorable to Parent and its stockholders from a financial point of view than the Merger (taking into account any proposal by Seller

to amend the terms of this Agreement, or any other proposal Seller may make in response to such Parent Acquisition Proposal); (B) that

is reasonably capable of being completed on the terms proposed, taking into account the identity of the Person making the Parent Acquisition

Proposal, any approval requirements and all other financial, regulatory, legal and other aspects of such Parent Acquisition Proposal;

and (C) for which financing, if a cash transaction (whether in whole or in part), is then fully committed or reasonably determined to

be available by the Board of Directors of Parent.

(ii) “Parent

Intervening Event” means any material event, change, effect, development or occurrence that was not known or reasonably foreseeable

to the Board of Directors of Parent as of or prior to the date of this Agreement, which event, change, effect, development or occurrence

thereafter becomes known to the Board of Directors of Parent and is not the result of a breach by Parent or its Subsidiaries of this Agreement;

provided that “Parent Intervening Event” shall exclude any event, change, effect, development or occurrence related

to (A) any change, in and of itself, in the market price or trading volume of Parent Common Stock, (B) Parent and its Subsidiaries meeting,

exceeding or failing to meet any internal or published projections, forecasts, estimates or predictions in respect of revenues, earnings

or other financial or operating metrics for any period, (C) any Parent Acquisition Proposal or other inquiry, offer or proposal that would

reasonably be expected to lead to a Parent Acquisition Proposal, (D) any delisting of the Parent Common Stock from Nasdaq or any ineligibility

of Parent to register a primary offering of Parent Common Stock in accordance with General Instruction I.B.1 of Form S-3 promulgated under

the Securities Act, (E) any action taken by either Party pursuant to the affirmative covenants set forth in Section 7.01, or the

consequences of any such action, or (F) the execution and delivery of this Agreement, the public announcement thereof, the pendency of

this Agreement, the impact thereof on the relationships of Parent and its Subsidiaries, with customers, suppliers or partners or the consummation

of the Merger.

Section 6.03. Director

and Officer Liability.

(a) From

and after the Closing until the sixth (6th) anniversary thereof, Parent shall, and shall cause the Surviving Company to (i) indemnify

and hold harmless and shall advance expenses as incurred, in each case to the same extent (subject to Applicable Law) such Persons are

indemnified as of the date of this Agreement by Seller or Parent, as applicable, pursuant to the Seller Organizational Documents, the

Parent Organizational Documents, the governing or organizational documents of any Subsidiary of Seller or of Parent and any indemnification

agreements in existence as of the date of this Agreement, each present and former director or officer of Seller, Parent and their respective

Subsidiaries (in each case, when acting in such capacity or in connection with their service as an officer, director or other fiduciary

of any other Person if such service was at the request or for the benefit of Seller, Parent or any of their respective Subsidiaries) (collectively,

the “D&O Indemnified Parties”) against any fees, reasonable out-of-pocket costs or expenses (including reasonable

out-of-pocket attorneys’ fees), judgments, inquiries, claims, fines, losses, damages or liabilities incurred in connection with

any threatened or actual Proceeding, whether civil, criminal, administrative or investigative, whether arising before or after the Closing,

arising out of the fact that such Person is or was a director or officer of Seller, Parent or any of their Subsidiaries or pertaining

to matters existing or occurring at or prior to the Closing, including the Transactions; provided, however, that all rights

to indemnification, exculpation and advancement of expenses in respect of any Proceeding asserted or made within such six (6)- year period

shall continue until the final disposition of such Proceeding; provided further that in the case of advancement of expenses, any

D&O Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined

that such D&O Indemnified Party is not entitled to indemnification; and (ii) reasonably cooperate in the defense of any such matter

until it is determined that such D&O Indemnified Party is not eligible for indemnification. Any D&O Indemnified Party wishing

to claim indemnification under this Section 6.03(a), upon learning of any such claim, action, suit, proceeding or investigation,

shall promptly notify Parent and the Surviving Company thereof, but the failure to so notify shall not relieve Parent or the Surviving

Company, as applicable, of any liability it may have to such D&O Indemnified Party except to the extent such failure materially prejudices

the indemnifying party.

(b) For

a period of six (6) years after the Closing, Parent shall, and shall cause the Surviving Company to, maintain in effect the policies of

directors’ and officers’ liability insurance maintained by Seller and Parent as of the Closing (“Current Insurance”)

(provided that Parent and the Surviving Company may substitute therefor policies with a substantially comparable insurer of at

least the same coverage and amounts containing terms and conditions that are no less favorable to the insureds) with respect to claims

arising from facts or events that occurred at or before the Closing; provided, however, that neither Parent nor the Surviving

Company shall be obligated to expend for any annual period an amount in excess of 300% of the current annual premium paid as of the date

of this Agreement by Seller or Parent, as applicable, for such insurance (the “Premium Cap”), and if such premium for

such insurance would at any time exceed the Premium Cap or such coverage is not otherwise available, then Parent and the Surviving Company

shall maintain insurance that, in Parent’s good faith determination, provides the maximum coverage available at an aggregate premium

equal to the respective Premium Cap. In lieu of the foregoing, Seller and Parent may obtain at or prior to the Closing six (6)-year “tail”

insurance under Seller’s or Parent’s, as applicable, respective Current Insurance providing equivalent coverage to that described

in the preceding sentence if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the

Premium Cap.

-60-

provisions of this Section 6.03 shall survive the Closing and are intended to be for the benefit of, and shall be enforceable by,

each D&O Indemnified Party and his or her heirs and representatives. If Parent, the Surviving Company, or any of their respective

successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving entity of such consolidation

or merger, or (ii) transfers all or substantially all of its assets to any other Person or engages in any similar transaction, then in

each such case, Parent and/or the Surviving Company, as applicable, will cause proper provision to be made so that the successors and

assigns of Parent and/or the Surviving Company, as applicable, will expressly assume the obligations set forth in this Section 6.03.

(d) At

or prior to the Closing, Parent shall enter into customary indemnification agreements reasonably satisfactory to Seller with each Person

who shall be a director or an officer of Parent immediately after the Closing, which indemnification agreements shall continue to be effective

following the Closing.

Section 6.04. Conversion

of Preferred Stock.

(a) Parent

shall (a) take any and all actions necessary to effect the Mandatory Conversion (as defined in the Support Agreement), and (b) deliver

a Forced Conversion Notice (as defined in the Series D Certificate of Designations) to the holders of shares of Parent Series D Preferred

Stock, providing that the Forced Conversion Date (as defined in the Series D Certificate of Designations) will be deemed to occur as of

immediately prior to the Effective Time, and take any and all actions necessary to effect the Series D Forced Conversion.

(b) No

fewer than three (3) Business Days prior to the Closing Date, Parent shall deliver to Seller a written statement (the “Closing

Statement”) including (i) its calculation of the Series C Conversion Price, to be calculated in accordance with Schedule 6.04(b)

attached hereto, and (ii) confirmation of the number of shares of Parent Series C Preferred Stock and Parent Series D Preferred Stock

that remain outstanding as of the date of the Closing Statement and the details of any conversions of Parent Series C Preferred Stock

and Parent Series D Preferred Stock from the date of this Agreement to the date of the Closing Statement. Parent shall consider in good

faith any reasonable comments to the calculation set forth in the Closing Statement notified by Seller to Parent in writing at least two

(2) Business Days prior to the Closing Date.

Section 6.05. Notice

to Warrant Holders. Promptly after the execution and delivery of this Agreement, Parent

shall notify the holders of all warrants to purchase shares of Parent Common Stock of the Transactions.

prior written consent of the other Party. Seller and Parent shall each have the responsibility for their respective filing fees associated

with filings pursuant to the HSR Act and all other antitrust and other regulatory filings with any Governmental Authority, including those

that may be required to be filed in any other jurisdiction.

to Applicable Law, each of Parent, Merger Sub and Seller shall, and shall cause their respective Subsidiaries to: (i) promptly notify

to any of the foregoing; (ii) consult with the other Party prior to participating in any meeting, telephone call or discussion with any

the Governmental Authority; and (iii) furnish the other Party with copies of all correspondence, filings and written communications (or

a reasonably detailed summary of any oral communications) between it and its Representatives, on the one hand, and any Governmental Authority

to Information; Confidentiality. Upon reasonable advance notice and subject to Applicable Law and solely for purposes of the

Transactions or transition or integration planning related thereto, each Party shall, and each Party shall cause its Subsidiaries to,

afford to the other Party and its Subsidiaries and their respective Representatives reasonable access, during normal business hours and

Subsidiaries shall use their reasonable best efforts to make appropriate substitute arrangements to permit reasonable disclosure not in

violation of any applicable Law or fiduciary duty), (c) as would be reasonably expected to result in the loss of any attorney-client,

work product or other legal privilege or protection (provided that the applicable Party and its Subsidiaries shall use their reasonable

regarding the deliberations of the Board of Directors of Seller, Parent or any of their respective Subsidiaries or any committee thereof

with respect to the Transactions or the entry into this Agreement, or any materials provided to the Board of Directors of Seller, Parent

Section 6.02(c) or effect a Parent Adverse Recommendation Change in accordance with Section 6.02(f), the rights of Parent

and its Subsidiaries and their Representatives under this Section 7.02 shall automatically terminate without further action as

of such time. All information exchanged pursuant to this Section 7.02 shall be subject to the terms of the Confidentiality Agreement.

Statement; Parent Stockholder Meeting.

(a) As

promptly as reasonably practicable after the execution and delivery of this Agreement (and in any event within twenty (20) Business Days

after the date hereof, unless otherwise agreed to by the Parties (email shall suffice)), Parent shall prepare (with Seller’s reasonable

cooperation (including causing its Subsidiaries and Representatives to cooperate)) and file with the SEC a proxy statement, in preliminary

Statement”). Each of Parent, Seller and Fortitude shall use their respective reasonable best efforts to cause the Proxy Statement

consultants and holders of Equity Interests and information regarding such other matters as may be reasonably necessary or advisable or

as may be reasonably requested in connection with the Proxy Statement, a Current Report on Form 8-K pursuant to the Exchange Act in connection

(b) Parent

shall promptly notify Seller upon the receipt of any comments from the SEC or its staff or any request from the SEC or its staff for additional

information or for amendments or supplements to the Proxy Statement and shall provide Seller with copies of all written correspondence,

and a description of all oral correspondence, between it and its Representatives, on the one hand, and the SEC and its staff, on the other

hand, relating to the Proxy Statement. Parent shall provide Seller a reasonable opportunity to review and propose comments on the Proxy

Statement prior to the filing thereof (and any amendments or supplements thereto) or any responses or other communications to the SEC

or its staff and shall in good faith consider such comments reasonably proposed by Seller for inclusion therein. Parent shall use its

reasonable best efforts to resolve all SEC comments with respect to the Proxy Statement as promptly as reasonably practicable after receipt

thereof, including if so requested by the SEC and its staff, by delivering customary tax representation letters to its counsel to enable

such counsel to deliver any tax opinions requested or required by the SEC to be submitted in connection therewith, and to cause the definitive

Proxy Statement to be mailed to the stockholders of Parent as of the record date established for the Parent Stockholders’ Meeting

as promptly as reasonably practicable after the earlier of the tenth (10th) day after the preliminary Proxy Statement is filed with the

SEC (if the SEC has not informed Seller that it will review the Proxy Statement) and the date on which the SEC confirms that it has no

further comments on the Proxy Statement. Unless a Parent Adverse Recommendation Change has been made, Seller shall include in the Proxy

Statement the Parent Board Recommendation.

of Parent and Seller shall ensure that none of the information supplied by or on its behalf for inclusion or incorporation by reference

in the Proxy Statement will, at the date it is first mailed to the stockholders of Parent and at the time of the Parent Stockholder Meeting,

contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order

to make the statements therein, in light of the circumstances under which they are made, not misleading.

(d) If

at any time prior to the Effective Time any information relating to Seller, Parent or any of their respective Subsidiaries, Affiliates,

directors or officers is discovered by Seller or Parent, which is required to be set forth in an amendment or supplement to the Proxy

Statement, so that neither of such documents would include any misstatement of a material fact or omit to state any material fact necessary

to make the statements therein, with respect to the Proxy Statement, in light of the circumstances under which they were made, not misleading,

the Party that discovers such information shall promptly notify the other Parties and an appropriate amendment or supplement describing

such information shall be promptly filed with the SEC and, to the extent required by Law, disseminated to the stockholders of Parent.

-65-

(e) As

promptly as reasonably practicable after the date that the definitive Proxy Statement is filed with the SEC, and in any event promptly

following the earlier of (i) the thirteenth (13th) day after the preliminary Proxy Statement is filed with the SEC (if the

SEC has not informed Parent that it will review the Proxy Statement) and (ii) the date on which the SEC confirms that it has no further

comments on the Proxy Statement, Parent shall (x) cause the Proxy Statement to be disseminated to stockholders of Parent in compliance

with Applicable Law, (y) duly give notice of a meeting of the stockholders of Parent (the “Parent Stockholder Meeting”)

in accordance with Parent’s Organizational Documents and Nasdaq Listing Rule 5620(b) with the record date and meeting date of the

Section 10.04. Interpretation;

Construction. When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article

or Section of this Agreement unless otherwise indicated. The table of contents, index of defined terms and headings contained in

this Agreement are for reference purposes only, do not constitute part of this Agreement and shall not affect in any way the meaning

or interpretation of this Agreement. Any capitalized term used in any Exhibit but not otherwise defined therein shall have the

meaning assigned to such term in this Agreement. Whenever the words “include,” “includes” or

“including” are used in this Agreement, they shall be deemed to be followed by the words “without

limitation.” The words “hereof,” “hereto,” “hereby,” “herein” and

“hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to

any particular provision of this Agreement. The words “date hereof” when used in this Agreement shall refer to the date

of this Agreement. The word “will” shall be construed to have the same meaning as “shall”. The words

“made available to Parent” and words of similar import refer to documents and other information posted to the Datasite

virtual data room by or on behalf of Seller at least one (1) day prior to the date of this Agreement. The words “made

available to Seller” and words of similar import refer to documents and other information posted to the Ideals virtual data

room by or on behalf of Parent at least one (1) day prior to the date of this Agreement. Unless the context requires otherwise, the

word “material” shall be construed in light of Parent and its Subsidiaries, taken as a whole, or Seller and its

Subsidiaries, taken as a whole, as the case may be. The term “or” is not exclusive. The word “extent” in the

phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase shall not mean simply

“if.” The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such

terms. Any agreement, instrument or Law defined or referred to herein means such agreement, instrument or Law as from time to time

amended, modified or supplemented, unless otherwise specifically indicated. References to a Person are also to its permitted

successors and assigns. Unless otherwise specifically indicated, all references to “dollars” and “$” will be

deemed references to the lawful money of the United States of America. No provision of this Agreement will be interpreted in favor

of, or against, any of the Parties to this Agreement by reason of the extent to which any such Party or its legal counsel

participated in the drafting thereof or by reason of the extent to which any such provision is inconsistent with any prior draft of

this Agreement, and no rule of strict construction will be applied against any Party hereto.

Section 10.05. Severability.

Any term or provision of this Agreement that is held by a court of competent jurisdiction or other Governmental Authority to be invalid,

void or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and

provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other

jurisdiction. If the final judgment of a court of competent jurisdiction or other Governmental Authority declares that any term or provision

of this Agreement is invalid, void or unenforceable, 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 are fulfilled to the

fullest extent possible.

Section 10.11. Assignment.

Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by

operation of Law or otherwise by any of the Parties without the prior written consent of the other Parties. Any purported assignment without

such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable

by, the Parties and their respective successors and permitted assigns.

Section 10.12. Specific

Performance. The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions

of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even

if available, would not be an adequate remedy therefor and therefore fully intend for specific performance to be an available remedy for

breaches of this Agreement. It is accordingly agreed that, prior to the termination of this Agreement pursuant to Section 9.01,

the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by any Party and to enforce specifically

the performance of terms and provisions of this Agreement in any court referred to in Section 10.10(a), without proof of actual

damages, this being in addition to any other remedy to which any Party is entitled at Law or in equity. The Parties further agree not

to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to object

to a remedy of specific performance on the basis that a remedy of monetary damages would provide an adequate remedy for any such breach.

The Parties further acknowledge and agree that the agreements contained in this Section 10.12 are an integral part of the Transactions,

including the Merger, and that, without these agreements, none of the Parties would enter into this Agreement. The Parties further agrees

that no Party shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining

any remedy referred to in this Section 10.12, and irrevocably waive any right it may have to require the obtaining, furnishing

or posting of any such bond or similar instrument.

Section 10.13. Amendment.

Subject to compliance with Applicable Law, this Agreement may be amended by all of the Parties, by action taken or authorized by their

respective boards of directors, at any time before or after the Parent Stockholder Approvals or the effectiveness of the Seller Consent;

provided that after the Parent Stockholder Approvals have been obtained or the Seller Consent has become applicable, any amendment

of this Agreement that by Applicable Law requires the further approval by Parent’s stockholders, the stockholders of Seller, the

member of Fortitude or the member of Merger Sub shall be effective only with the approval of such stockholders or members, as applicable.

This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties.

Section 10.14. Extension;

Waiver. At any time prior to the Effective Time, Seller and Parent (on behalf of itself or Merger Sub) may, to the extent legally

allowed, (a) extend the time for the performance of any of the obligations or other acts of Seller, in the case of Parent, or Parent or

Merger Sub, in the case of Seller, (b) waive any inaccuracies in the representations and warranties of Seller, in the case of Parent,

or Parent or Merger Sub, in the case of Seller, contained in this Agreement, and (c) waive compliance by Seller, in the case of Parent,

or Parent or Merger Sub, in the case of Seller, with any of the agreements or conditions contained in this Agreement. Any agreement on

the part of a Party to any such extension or waiver will be valid only if set forth in a written instrument signed by an authorized officer

on behalf of such Party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement

or condition will not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

Section 10.15. Non-Recourse.

Each Party agrees, on behalf of itself and its respective Affiliates, that all actions, claims, obligations, liabilities or causes of

action (whether in Contract or in tort, in Law or in equity, or granted by statute, whether by or through attempted piercing of the corporate,

limited partnership or limited liability company veil) that may be based upon, in respect of, arise under, out or by reason of, be connected

with, or relate in any manner to: (a) this Agreement or the Transactions, (b) the negotiation, execution or performance of this Agreement

(including any representation or warranty made in, in connection with, or as an inducement to, this Agreement), (c) any breach or violation

of this Agreement and (d) any failure of the Transactions to be consummated, in each case, may be made only against (and are those solely

of) the Parties that are expressly identified as parties to this Agreement. In furtherance and not in limitation of the foregoing, and

notwithstanding anything contained in this Agreement to the contrary, each Party hereto covenants, agrees and acknowledges, on behalf

of itself and their respective Affiliates, that no recourse under this Agreement or in connection with any of the Transactions shall be

had against any other Person, and no other Person shall have any liabilities or obligations (whether in Contract or in tort, in Law or

in equity, or granted by statute, whether by or through attempted piercing of the corporate, limited partnership or limited liability

company veil) for any claims, causes of action, obligations or liabilities arising under, out of, in connection with or related in any

manner to the items in the immediately preceding clauses (a) through (d), it being expressly agreed and acknowledged that no personal

liability or losses whatsoever shall attach to, be imposed on or otherwise be incurred by any of the aforementioned, as such, arising

under, out of, in connection with or related in any manner to the items in the immediately preceding clauses (a) through (d). No Person,

other than the Parties, shall be responsible or liable for any damages which may be alleged as a result of this Agreement or the Transactions

(or the termination or abandonment thereof). Notwithstanding anything to the contrary set forth in this Section 10.15, it is expressly

understood and agreed that none of the foregoing shall limit, impair or otherwise affect the rights, liabilities or obligations of any

Person arising out of or relating to the Confidentiality Agreement or the Support Agreements to the extent such Person is expressly party

thereto.

Section 10.16. Fees

and Expenses. Except as otherwise expressly provided in this Agreement (including the terms of Article IX), all costs and expenses

incurred in connection with this Agreement, the Merger and the other Transactions will be paid by the Party incurring such costs and expenses.

Section 10.17. Disclosure

Letter References and SEC Document References. The Parties hereto agree that each section or subsection of the Seller Disclosure

Letter or the Parent Disclosure Letter, as applicable, shall be deemed to qualify the corresponding Section or subsection of this Agreement,

irrespective of whether or not any particular Section or subsection of this Agreement specifically refers to the Seller Disclosure Letter

or the Parent Disclosure Letter, as applicable. The Parties hereto further agree that (other than with respect to any items disclosed

in Section 3.13 of the Seller Disclosure Letter and Section 4.14 of the Parent Disclosure Letter, in each case, for which

an explicit reference in any other section shall be required in order to apply to such section) disclosure of any item, matter or event

in any particular section or subsection of either the Seller Disclosure Letter or the Parent Disclosure Letter shall be deemed disclosure

with respect to any other section or subsection of the Seller Disclosure Letter or the Parent Disclosure Letter, as applicable, to which

the relevance of such disclosure would be reasonably apparent on its face, without review of the underlying documents, notwithstanding

the omission of a cross-reference to such other section or subsections. The Parties hereto agree that in no event shall any disclosure

contained in any part of any Parent SEC Document entitled “Risk Factors,” “Forward Looking Statements,” “Cautionary

Statement About Forward Looking Statements,” “Special Note on Forward Looking Statements” or “Forward Looking

Information” or containing a description or explanation of “Forward Looking Statements” or any other disclosures in

any Parent SEC Document that are cautionary, predictive or forward-looking in nature be deemed to be an exception to (or a disclosure

NOW, THEREFORE, in consideration

of the foregoing and the mutual representations, warranties, covenants and agreements contained herein, and intending to be legally bound

hereby, the parties hereto hereby agree as follows:

Article

VOTING

1.1. Agreement

to Vote. The Stockholder agrees that, from and after the date of this Agreement and until the earlier to occur of (x) receipt

of the Parent Stockholder Approvals and (y) the valid termination of the Merger Agreement in accordance with its terms (such earlier date,

the “Voting Covenant Expiration Date”), at the Parent Stockholder Meeting or any other meeting of the stockholders

of Parent, however called, and at every adjournment or postponement thereof, or in connection with any written consent of the stockholders

of Parent, in each case relating to any proposed action by the stockholders of Parent with respect to the matters set forth in Section

1.1(b) below (each, a “Voting Event”), the Stockholder shall:

(a) appear at each such

Voting Event or otherwise cause the Shares that are capable of being voted and any voting securities of Parent acquired by the

Stockholder after the date of this Agreement and prior to the record date of such Voting Event (the “Voting

Shares”) owned beneficially or of record by the Stockholder to be counted as present thereat for purposes of calculating a

quorum for such Voting Event; and

(b) vote

Amendments, (B) the approval pursuant to Listing Rule 5635 of Nasdaq of (1) the issuance of shares of Parent Class V Common Stock as contemplated

agreed by Parent and Seller to be necessary or appropriate in connection with the Transactions, including, without limitation, as to the

matters set forth in Section 1.5; (iii) in favor of any proposal to adjourn or postpone a meeting of the stockholders of Parent,

if necessary, to permit further solicitation of proxies because there are not sufficient votes to approve and adopt any of the foregoing

on the date on which such meeting is held; (iv) against any Parent Acquisition Proposal or any other proposal in opposition to, or in

competition with, the Merger and the other Transactions; and (v) against any other action, agreement or transaction that is intended to,

or would reasonably be expected to, impede, interfere with, delay, postpone or discourage the Transactions or this Agreement or the performance

by Parent of its obligations under the Merger Agreement or by the Stockholder of its obligations under this Agreement.

Prior to the Voting Covenant

Expiration Date, the Stockholder shall not enter into any agreement or understanding with any Person to vote or give instructions in any

manner inconsistent with the foregoing clauses (a) or (b).

1.2. Irrevocable

Proxy. The Stockholder hereby irrevocably grants to, and appoints, Seller and Parent, and any individual designated in writing

by Seller or Parent, and each of them individually, as the Stockholder’s proxy and attorney-in-fact (with full power of substitution),

for and in the name, place and stead of the Stockholder, to vote its Voting Shares with respect to a Voting Event, or grant a consent

or approval in respect of its Voting Shares with respect to a Voting Event, in a manner consistent with Section 1.1 and Section

1.5 if the Stockholder has not voted such Voting Shares in a manner consistent with Section 1.1 at least five (5) Business

Days prior to the applicable voting deadline. The proxy granted to Seller and Parent in this Section 1.2 shall expire on the Voting

Covenant Expiration Date. The Stockholder understands and acknowledges that Seller is entering into the Merger Agreement in reliance upon

the Stockholder’s execution and delivery of this Agreement. The Stockholder hereby affirms that the irrevocable proxy set forth

in this Section 1.2 is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given

to secure the performance of the duties of the Stockholder under this Agreement. The Stockholder hereby further affirms that the irrevocable

proxy set forth in this Section 1.2 is coupled with an interest and may under no circumstances be revoked. The Stockholder hereby

ratifies and confirms all actions and things that such irrevocable proxy may lawfully do or cause to be done by virtue hereof. Such irrevocable

proxy is executed and intended to be irrevocable in accordance with the provisions of Sections 21.367-373 of the TBOC. Notwithstanding

the foregoing, the proxy and appointment granted hereby shall be automatically revoked, without any action by the Stockholder, upon any

valid termination of this Agreement pursuant to Section 4.1.

1.3. Certain

Adjustments. In case of a stock dividend or distribution of voting securities of Parent, or any change in the Parent

Common Stock by reason of any stock dividend or distribution or any reclassification, recapitalization, stock split (including a

reverse stock split), merger, combination, exchange, consolidation or similar readjustment of shares, the term “Voting

Shares” shall be deemed to refer to and include the Voting Shares as well as all such stock dividends and distributions of

voting securities of Parent and any voting securities into which or for which any or all of the Voting Shares may be changed or

exchanged.

1.4. Capacity

as Stockholder. The Stockholder signs this Agreement solely in the Stockholder’s capacity as a stockholder of Parent,

and not in the Stockholder’s capacity as (a) a director, officer or employee of Parent or any of its Subsidiaries or (b) a trustee

or fiduciary of any employee benefit plan or trust. Notwithstanding anything herein to the contrary, nothing herein shall in any way restrict

a director or officer of Parent in the exercise of his or her fiduciary duties as a director or officer of Parent or in his or her capacity

as a trustee or fiduciary of any employee benefit plan or trust or prevent or be construed to create any obligation on the part of any

director or officer of Parent or any trustee or fiduciary of any employee benefit plan or trust from taking any action in his or her capacity

as such director, officer, trustee or fiduciary (including voting in favor of any Parent Adverse Recommendation Change) and no such action

or omission shall be deemed a breach of this Agreement.

1.5. Series

C Preferred Stock Matters. To the extent that the Stockholder is the record or beneficial owner of any shares of Parent Series C Preferred

Stock, the Stockholder agrees that:

(a) Consent

to Mandatory Conversion. The Stockholder irrevocably consents, pursuant to Section 5.1(b) of the Series C Certificate of Designations,

to the mandatory conversion in accordance with Section 4.1.1 of the Series C Certificate of Designations, of all outstanding shares of

Parent Series C Preferred Stock into shares of Parent Common Stock using the then-effective Series C Conversion Price (as such term is

defined in the Series C Certificate of Designations), contingent upon and effective as of either (i) if there is a Pre-Closing PIPE Investment,

immediately after the consummation of such Pre-Closing PIPE Investment (which itself shall occur immediately after the Closing) or (ii)

if there is no Pre-Closing PIPE Investment, immediately after the Effective Time (the “Mandatory Conversion”). Parent

acknowledges and agrees that the Stockholder’s foregoing consent, together with the consents of the other Requisite Holders (as

defined in the Series C Certificate of Designations) constitute the valid written consent required by Section 5.1(b) of the Series C Certificate

of Designations, and that no further action by any Person is required to give effect to the Mandatory Conversion.

(b) Consent

to Parent Class V Common Stock. The Stockholder irrevocably consents, pursuant to Section 3.2 of the Series C Certificate of Designations,

to the amendment of Parent’s Certificate of Formation to create a new class of Parent Common Stock, the Parent Class V Common Stock

(the “Parent Class V Common Stock Consent”). Parent acknowledges and agrees that the Stockholder’s foregoing

consent, together with the consents of the other Requisite Holders (as defined in the Series C Certificate of Designations) constitute

the valid written consent required by Section 3.2 of the Series C Certificate of Designations, and that no further action by any Person

is required to give effect to the Parent Class V Common Stock Consent.

of Deemed Liquidation Event. The Stockholder irrevocably elects, pursuant to Section 2.3.1 of the Series C Certificate of Designations,

that the consummation of the Transactions shall not constitute or give rise to a Deemed Liquidation Event (as defined in the Series C

Certificate of Designations) (the “Deemed Liquidation Event Waiver”). Each of Parent and Stockholder acknowledges and

agrees that the Stockholder’s foregoing election, together with the elections of the other Requisite Holders (as defined in the

Series C Certificate of Designations) constitute the valid written notice required by Section 2.3.1 of the Series C Certificate of Designations,

and that no further action by any Person (including, without limitation, Parent) is required to give effect to the Deemed Liquidation

Event Waiver.

(d) Omnibus

Waiver. For the avoidance of doubt, the consents and waivers described in the foregoing clauses (a)-(c), together with the consents

and waivers of the other Requisite Holders constitute an omnibus waiver in respect of such matters as authorized by Section 7 of the Series

C Certificate of Designations on behalf of all holders of Parent Series C Preferred Stock.

material breach of any of its representations, warranties, covenants or agreements set forth in this Agreement prior to the

termination of this Agreement pursuant to clauses (b) or (c) of this Section 4.1.

4.2. No

4.4. Mutual

Drafting; Interpretation; Construction. Each party hereto has participated in the drafting of this Agreement, which each party

hereto acknowledges is the result of extensive negotiations between the parties hereto. If an ambiguity or question of intent or interpretation

arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise

favoring or disfavoring any party hereto by virtue of the authorship of any provision. When a reference is made in this Agreement to an

Article or Section, such reference shall be to an Article or Section of this Agreement unless otherwise indicated. The headings contained

in this Agreement are for reference purposes only, do not constitute part of this Agreement and shall not affect in any way the meaning

or interpretation of this Agreement. Any capitalized term used in any Exhibit but not otherwise defined therein shall have the meaning

assigned to such term in this Agreement. Whenever the words “include,” “includes” or “including” are

used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,”

“hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in

this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The words “date hereof”

when used in this Agreement shall refer to the date of this Agreement. The word “will” shall be construed to have the same

meaning as “shall.” The term “or” is not exclusive. The word “extent” in the phrase “to the

extent” means the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” The

definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. Any agreement, instrument

or Law defined or referred to herein means such agreement, instrument or Law as from time to time amended, modified or supplemented, unless

otherwise specifically indicated. References to a Person are also to its permitted successors and assigns. No provision of this Agreement

will be interpreted in favor of, or against, any of the parties to this Agreement by reason of the extent to which any such party or its

legal counsel participated in the drafting thereof or by reason of the extent to which any such provision is inconsistent with any prior

draft of this Agreement, and no rule of strict construction will be applied against any party hereto.

4.5. Counterparts.

This Agreement may be executed in counterparts (each of which shall be deemed to be an original but all of which taken together

shall constitute one and the same agreement) and shall become effective when one or more counterparts have been signed by each of

the parties hereto and delivered (including by electronic communication) to the other parties hereto. No party hereto shall raise

the use of email to deliver a signature or the fact that any signature or Contract was transmitted or communicated by email with

scan attachment as a defense to the formation of a legally binding contract, and each such party forever waives any such

defense.

4.6. Entire

Agreement; Third-Party Beneficiaries. This Agreement (including any exhibits and schedules hereto) constitutes the entire agreement,

and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, between the parties

hereto, or any of them, with respect to the subject matter of this Agreement and thereof and is not intended to and shall not confer upon

any person other than the parties hereto any rights or remedies hereunder; provided, however, that Parent shall be an express

third-party beneficiary of the Stockholder’s obligations under Sections 1.1, 1.5, 3.1 and 3.2 and shall

be entitled to enforce such obligations as if it were a party hereto.

4.7. Governing

Law and Venue; Waiver of Jury Trial.

(a) THIS

AGREEMENT SHALL IN ALL RESPECTS BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE WITHOUT

REGARD TO CONFLICTS OF LAW PRINCIPLES, WHETHER OF THE STATE OF DELAWARE OR ANY OTHER JURISDICTION. Each of the parties hereto hereby irrevocably

and unconditionally consents and submits, for itself and with respect to its property, to the exclusive jurisdiction of the Court of Chancery

of the State of Delaware and the appropriate respective appellate courts therefrom (or only if the Court of Chancery of the State of Delaware

declines to accept or does not have jurisdiction over a particular matter, any federal court located in the State of Delaware and the

appropriate respective appellate courts therefrom or only if such federal courts located in the State of Delaware decline to accept or

do not have jurisdiction over a particular matter, any state court located in the State of Delaware) solely in respect of the interpretation

and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the Transactions,

and hereby waives, and agrees not to assert, as a defense in any action, suit or Proceeding for the interpretation or enforcement of this

Agreement or of any such document, that it is not subject to the jurisdiction thereto or that such action, suit or Proceeding may not

be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document

may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such action or Proceeding

shall be heard and determined in the Court of Chancery of the State of Delaware (or only if the Court of Chancery of the State of Delaware

declines to accept or does not have jurisdiction over a particular matter, any federal court located in the State of Delaware and the

appropriate respective appellate courts therefrom or only if such federal courts located in the State of Delaware decline to accept or

do not have jurisdiction over a particular matter, any state court located in the State of Delaware). The parties hereto hereby consent

to and grant any such court jurisdiction over the person of such parties and, to the extent permitted by Law, over the subject matter

of such dispute and agree that mailing of process or other papers in connection with any such action or Proceeding in the manner provided

in Section 4.3 or in such other manner as may be permitted by Law shall be valid and sufficient service thereof.

(b) EACH PARTY HERETO

ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT

ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE

LAW ANY AND ALL RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING

TO THIS AGREEMENT, OR THE TRANSACTIONS AND THEREBY OR TO THE ACTIONS OF THE PARTIES HERETO IN THE NEGOTIATION, ADMINISTRATION,

PERFORMANCE AND ENFORCEMENT HEREOF. EACH PARTY HERETO CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF

THE OTHER PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO

ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY HERETO UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH

PARTY HERETO MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH PARTY HERETO HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER

THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 4.7.

4.8. Specific

Performance. Each party hereto acknowledges and agrees that irreparable damage would occur in the event that any of the provisions

of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even

if available, would not be an adequate remedy therefor and therefore fully intend for specific performance to be an available remedy for

breaches of this Agreement. It is accordingly agreed that, prior to the termination of this Agreement pursuant to Section 4.1,

each party hereto shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by the other party hereto and

to enforce specifically the performance of terms and provisions of this Agreement in any court referred to in Section 4.7(a), without

proof of actual damages, this being in addition to any other remedy to which such party is entitled at Law or in equity. Each party hereto

further agrees not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason,

nor to object to a remedy of specific performance on the basis that a remedy of monetary damages would provide an adequate remedy for

any such breach. Each party hereto further acknowledges and agrees that the agreements contained in this Section 4.8 are an integral

part of the Merger and the other Transactions and that, without these agreements, each party hereto would not enter into this Agreement.

Each party hereto further agrees that the other party hereto shall not be required to obtain, furnish or post any bond or similar instrument

in connection with or as a condition to obtaining any remedy referred to in this Section 4.8, and irrevocably waives any right

it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

4.9. Amendment.

This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. Notwithstanding the

foregoing, no failure or delay by any party hereto in exercising any right hereunder shall operate as a waiver thereof nor shall any single

or partial exercise thereof preclude any other or further exercise of any other right hereunder.

4.10. Severability.

Any term or provision of this Agreement that is held by a court of competent jurisdiction or other Governmental Authority to be invalid,

void or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and

provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other

jurisdiction. If the final judgment of a court of competent jurisdiction or other Governmental Authority declares that any term or provision

of this Agreement is invalid, void or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to

effect the original intent of the parties hereto as closely as possible in an acceptable manner to the end that the Transactions are fulfilled

to the fullest extent possible.

4.11. Assignment.

Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by

operation of Law or otherwise by any of the parties hereto without the prior written consent of the other party hereto. Any purported

assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit

of, and be enforceable by, the parties hereto and their respective successors and permitted assigns.

Exhibit

99.1

Fortitude

and HeartSciences (Nasdaq: HSCS) Announce Business Combination, Aiming to Bring a

Leading Vertically-Integrated Zcash Mining

Platform to the Public Markets

Combined

company expected to operate under the Fortitude brand and to trade on Nasdaq under the ticker symbol

“TUDE”;

transaction expected to close in H2 2026

Upon

completion of the transaction, Fortitude believes it will be the first publicly traded venture mining platform with a

track record of

identifying high-conviction, early-stage Proof-of-Work opportunities

Fairport,

N.Y. — June 23, 2026 — [BUSINESSWIRE] – Fortitude Mining Holdings, Inc. (“Fortitude”), a

vertically-integrated digital asset mining platform anchored in Zcash, and HeartSciences Inc. (Nasdaq: HSCS) (“HeartSciences”),

an AI-powered medical technology company, today announced that they have entered into a definitive merger agreement to combine in an

all-stock transaction (the “Proposed Transaction”) which is expected to close in H2 2026. Upon closing, the combined

company will operate under the Fortitude brand and under the leadership of Fortitude’s management team—led by Fortitude

CEO Andrea Childs—and is expected to trade on the Nasdaq Capital Market under the ticker symbol “TUDE”, subject to

Nasdaq approval. Current HeartSciences CEO Andrew Simpson is expected to continue to lead the healthcare business unit after closing.

Additional transaction materials are available on Fortitude’s website.

Fortitude

is a leading Zcash mining platform that is currently wholly-owned by Digital Currency Group (“DCG”), and which applies a

venture mining approach across high-growth digital assets with a primary focus on Zcash, a privacy-preserving, Proof-of-Work asset. Launched

in 2016 from Bitcoin’s codebase, Zcash shares Bitcoin’s defining attributes, including a fixed 21 million coin supply, while

adding robust privacy technology. Zcash’s shielded transaction pool is designed to enable private transactions, addressing growing

demand for financial privacy as economic activity continues to move on-chain. Zcash has delivered a trailing twelve-month return of approximately 1,000%+ as of June 15, 20261.

Fortitude

began mining ZEC, the native token of the Zcash network, in 2019 and has scaled its annualized production to 157,000 ZEC (approximately

366 ZEC per day) as of May 31st, 2026. Drawing on a multi-year track record in Proof-of-Work mining, Fortitude’s platform integrates

institutional grade operations, power infrastructure, and strategic capital deployment across three areas:

● Vertically-Integrated

Zcash Strategy: Fortitude’s approach includes hardware procurement, infrastructure

deployment, and research and development, driving low-cost Zcash production and meaningful

operating leverage to price appreciation. Fortitude intends to continue building a significant

long-term strategic Zcash position.

● Venture

Mining: Fortitude focuses on capturing high-margin opportunities in early-stage

Proof-of-Work protocols where it has high conviction, deploying capital and operational expertise

honed over years of mining. Fortitude’s current Zcash position is a proven example

of this approach.

● Power

Portfolio: Fortitude owns and operates a diversified portfolio of data center capacity

backed by competitive long-term power contracts, with a focus on disciplined acquisitions

and greenfield developments that reduce costs and provide meaningful accretion.

1 Source:

Investing.com (ZEC/USD), as of June 15, 2026. Trailing-twelve-month return reflects the change in the ZEC/USD spot price over the twelve

months ended June 15, 2026. Cryptocurrency prices are highly volatile; past performance is not indicative of future results.

“Fortitude’s

business model is designed to allow us to move quickly when we see promising opportunities. We own and operate a diversified power portfolio

with competitive long-term contracts, control our infrastructure buildout, and deploy capital selectively,” said Andrea Childs,

CEO of Fortitude. “As a public company, we anticipate having the flexibility and access to capital to accelerate our core venture

mining platform and continue pursuing high-return opportunities in the Proof-of-Work ecosystem, including our long-standing position

in Zcash. I would like to thank the entire HeartSciences team for their continued collaboration as we work towards our combined future.”

“We

believe Zcash represents one of the most compelling opportunities in digital assets,” said Barry Silbert, Founder and

CEO of DCG. “It combines Bitcoin’s scarcity and Proof-of-Work discipline with privacy and security properties that we expect

will matter more as financial systems become increasingly digital. Zcash is a clear example of Fortitude’s venture mining

model in action: early conviction in an important protocol, paired with the infrastructure required to support and scale it.”

“During

2025, we were introduced to a number of potential transactions, and Fortitude stood out as the right one for our shareholders. This combination

gives our shareholders continued ownership in a business operating at scale, while allowing us to keep advancing MyoVista Insights and

our AI-enabled ECG technology with greater focus, free of the constant cycle of raising capital. We believe it represents a strong path

forward for our shareholders and the company overall,” said Andrew Simpson, CEO of HeartSciences.

Proposed

Transaction Highlights:

● Existing

Fortitude sole stockholder, DCG, is expected to own approximately 95% of the combined company

at closing (on a fully diluted basis), reflecting their continued conviction in the business.

● Expected

to close in the second half of 2026, subject to customary closing conditions, including approval

by the shareholders of HeartSciences.

Disclaimers (Cont'd) Forward-Looking Statements This presentation includes forward-looking statements. These forward-looking statements generally can be identified by the use of words such as "anticipate," "expect," "plan," "could," "may," "will," "believe," "estimate," "forecast," "goal," "project," "potential," "target," "objective," "intend," and other words of similar meaning. These forward-looking statements address various matters including, but not limited to, statements relating to the anticipated benefits, terms, size, and completion of the Proposed Transaction, the expected future market and price of Zcash and other digital assets, the amount of Zcash to be held by Fortitude, Fortitude's upside potential beyond the core Zcash business, the projected financial performance at an illustrative range of Zcash token prices, the illustrative future state of key components of Fortitude Business, including average daily ZEC production, Zcash cash COGS per coin, other cash COGS per coin and, the expected rate of increase of Fortitude's profitability compared to Zcash price movement, the management's strategies and decisions aimed at maximizing return on invested capital, Fortitude's planned acquisitions of mining data centers and expansion of power portfolio expected to reduce cost and provide revenue optionality, HSCS's belief in AI-ECG enabling more effective treatment and earlier diagnosis of heart disease and the timing of 510(k) regulatory approval of MyoVista wavECG. Each forward-looking statement contained in this presentation is subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statement, including among others, the risk that the Proposed Transaction described herein may not be completed in a timely manner or at all; failure to realize the anticipated benefits of the Proposed Transaction; changes in business, market, financial, political and regulatory conditions; and risks relating to our operations and business, and HeartSciences' common stock, including the risk factors described in the Appendix attached hereto and in the section entitled "Risk Factors" of HeartSciences'Annual Report on Form 10-K for the year ended April 30, 2025 filed with the SEC, as may be updated from time to time in HeartSciences' subsequent Quarterly Reports on Form 10-Q, and in other filings that HeartSciences makes with the SEC. We caution investors not to place considerable reliance on the forward-looking statements contained in this presentation. You are encouraged to read HeartSciences' filings with the SEC, available at www.sec.gov, for a discussion of these and other risks and uncertainties. The forward-looking statements in this presentation speak only as of the date of this document, and we undertake no obligation to update or revise any of these statements. Our business is subject to substantial risks and uncertainties, including those referenced above. Investors, potential investors, and others should give careful consideration to these risks and uncertainties. The risk factors described in this presentation, including those relating to digital assets and proof-of-work mining, are not intended to be exhaustive and should be considered in conjunction with, and not as a substitute for, your own independent assessment. The digital asset industry is characterized by rapid technological change, evolving regulatory frameworks, and significant market volatility. Additional risks and uncertainties–such as changes to network protocols (including forks or shifts in consensus mechanisms), increases in mining difficulty or hash rate, disruptions in access to power, cybersecurity threats, and uncertain legal or tax treatment of digital assets–may arise or become material over time and could have a material adverse effect on our business, financial condition, results of operations, or the value of any securities issued in connection with the Proposed Transaction. Past Performance In all cases where historical results are presented or past performance is described, we note that past performance is not a reliable indicator of future results and performance. STRICTLY PRIVATE AND CONFIDENTIAL 3

Disclaimers (Cont'd) Non-GAAP Information This presentation includes information based on financial measures that are not recognized under generally accepted accounting principles in the United States ("GAAP"), such as Fortitude's Adjusted EBITDA and Adjusted General & Administrative Expense. References to "Adjusted EBITDA" mean earnings before interest, taxes, depreciation and amortization, or EBITDA, adjusted for the transaction related expenses and legal non-recurring expenses. Adjusted General & Administrative Expense means General & Administrative Expense, which is further adjusted for the transaction expenses, legal non-recurring expenses and certain other one-time expenses. Such non-GAAP financial measures are presented only as a supplement to Fortitude's financial statements based on GAAP. Non-GAAP financial information is provided to enhance understanding of Fortitude's financial performance, but non-GAAP financial measures are not recognized terms under GAAP, and non-GAAP measures should not be considered in isolation from, or as a substitute analysis for, the company's results of operations as determined in accordance with GAAP. Fortitude uses non-GAAP measures in its operational and financial decision making and believes that such non-GAAP numbers are more representative of the performance of the business and thus instructive for management's strategic planning. Specifically, with respect to each of Adjusted EBITDA and Adjusted General & Administrative Expense, Fortitude believes it is useful to exclude certain items in order to allow for period-over-period comparisons on a more consistent basis and to focus on what it regards to be a more meaningful indicator for evaluating the underlying operating performance of the business. Fortitude also believes that investors may find non-GAAP financial measures useful for the same reasons, although investors are cautioned that non-GAAP financial measures are not a substitute for GAAP disclosures. Net income is the GAAP measure most directly comparable to Adjusted EBITDA. General & Administrative Expense is the GAAP measure most directly comparable to Adjusted General & Administrative Expense. In evaluating both Adjusted EBITDA and Adjusted General & Administrative Expense, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in such presentation. The non-GAAP financial measures are not presented in accordance with GAAP. Please refer to the appendix of this presentation for reconciliations of non-GAAP financial measures contained herein to the most directly comparable GAAP measures. A quantitative reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP measures is not provided because certain reconciling items cannot be reasonably predicted or estimated without unreasonable effort. Please refer to the appendix for further description. Non-GAAP measures are frequently used by securities analysts, investors and other interested parties in their evaluation of companies comparable to Fortitude, many of which present non-GAAP measures when reporting their results. Non-GAAP measures have limitations as an analytical tool. They are not presentations made in accordance with GAAP and are not measures of financial condition or liquidity. Some of these limitations are: (i) both Adjusted EBITDA and Adjusted General & Administrative Expense exclude the transaction-related expenses and non-recurring legal expenses we have incurred, such as litigation costs and one time accounting charges; (ii) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and the cash requirements for such replacements are not reflected in Adjusted EBITDA; (iii) the omission of the amortization expense associated with our intangible assets further limits the usefulness of Adjusted EBITDA; and (iv) Adjusted EBITDA does not include the payment of taxes, which is a necessary element of our operations. Because of these limitations, such non-GAAP measures should not be considered as an alternative to profit or loss for the period determined in accordance with GAAP or operating cash flows determined in accordance with GAAP. Management compensates for these limitations by not viewing the non-GAAP measures in isolation and specifically by using other GAAP measures to measure our operating performance. Fortitude's non-GAAP measures are not necessarily comparable to similarly titled measures used by other companies. As a result, you should not consider such performance measures in isolation from, or as a substitute analysis for, the company's results of operations as determined in accordance with GAAP. Preliminary Unaudited Results Included in this presentation are selected preliminary unaudited financial results as of and for the period beginning January 1, 2026 and ended April 30, 2026. These preliminary financial results have been prepared in good faith by the management on a consistent basis with prior periods. However, we have not completed our financial closing procedures for the period ended April 30, 2026 and actual results could be materially different from these preliminary financial results. The Company's independent registered public accounting firm has not conducted an audit or review of and does not express an opinion or any other form of assurance with respect to, the preliminary financial results. During the course our financial closing procedures for the period ended April 30, 2026, we may identify items that would require us to make material adjustments to the preliminary financial results presented herein. As a result, you should not place undue reliance on these preliminary unaudited results and should not draw any inferences from this information regarding financial or operating data not provided. These preliminary financial results should not be viewed as a substitute for full financial statements prepared in accordance with U.S. GAAP. STRICTLY PRIVATE AND CONFIDENTIAL 4

Disclaimers (Cont'd) Projections This presentation contains projected financial information with respect to Fortitude, including an illustrated revenue, gross profit, Adjusted EBITDA, Adjusted General & Administrative Expense, and Adjusted EBITDA margin analysis at various Zcash prices. All such financial projections are forward-looking statements, which are based on assumptions that are inherently uncertain. These projections are presented for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such projected information are inherently uncertain and are subject to a wide variety of significant business, regulatory, economic and competitive risks and uncertainties. Significant assumptions underlying financial projections included in the presentation include, among others, currently Fortitude operates ~5.2 GSol/s of Zcash miners and expects an additional ~3.3 to 4.7 GSol/s of new miner deliveries throughout the course of 2026; Zcash network hashrate of 24.0 GSol/s by December 2026; weighted average Zcash fleet uptime of 84%, Zcash pool fees of 2%, no Zcash network transaction fees, Zcash cash COGS per coin of $70, annualized Bitcoin mining revenue of ~$27mm based on preliminary, unaudited YTD results through 4/30/2026, and annualized other revenue of ~$1.8mm based on preliminary, unaudited YTD results through 4/30/2026, each of which is subject to assumptions that may prove incorrect. Even if the assumptions underlying financial projections are correct, actual results may be significantly impacted by a variety of factors outside our control, including, but not limited to, the number of machines actually purchased, the ability to successfully deploy the latest generation miners and the ability to achieve lower power costs. All of the projected financial information included in this presentation has been prepared by and is the responsibility of Fortitude's management and has not been audited, reviewed or compiled by an independent registered public accounting firm. Accordingly, there can be no assurance that financial projections are indicative of future performance or that actual results will not differ materially from those presented herein. Inclusion of financial projections in this presentation should not be regarded as a representation by any person that the results contained in the projected information will be achieved. No representation is made regarding the reasonableness or completeness of the assumptions underlying financial projections, modeling or any other information contained in this presentation.

Risk Factors STRICTLY PRIVATE AND CONFIDENTIAL STRICTLY PRIVATE AND CONFIDENTIAL 25

Risk factors (1/4) Risk Factors The following is a summary of the principal factors that make an investment in our securities speculative or risky. As used herein "we", "us" and "our" refers to Fortitude Mining Holdings, Inc. ("Fortitude"), HeartSciences Inc. ("HSCS"), or the proposed combined company as context requires. This summary should not be relied upon as an exhaustive summary of the material risks facing our business, or the potential business combination (the "Proposed Transaction"). Investing in HSCS's securities involves a high degree of risk. Certain factors may have a material adverse effect on our business, financial condition and results of operations and your potential investment in us. Please also refer to the risk factors disclosed in HSCS's filings with the U.S. Securities and Exchange Commission (the "SEC"), including those discussed in the section entitled "Risk Factors" of HSCS's Annual Report on Form 10-K for the year ended April 30, 2025 filed with the SEC, as may be updated from time to time in HSCS's subsequent Quarterly Reports on Form 10-Q, and in other filings that HSCS makes with the SEC. The risks and uncertainties described below (and those in HSCS's SEC filings) are not the only ones that we face. Additional risks that we are unaware of, or that we currently believe are not material, may also become important factors that materially adversely affect us. If any of the risk factors discussed in HSCS's SEC filings or any of the following risks actually occur, our business, financial condition, results of operation, and future prospects could be adversely affected, the trading price of HSCS's common stock could decline, and you could lose all or part of your potential investment. 26 STRICTLY PRIVATE AND CONFIDENTIAL

Risk factors (2/4) Risks Related to Fortitude's Business ▪ We are subject to counterparty risks, including risks and uncertainties relating to our mining site hosting partners. ▪ Our limited rights of legal recourse and lack of insurance over our cryptocurrency holdings expose us to the risk of loss in the event of theft or destruction, for which there may be no adequate remedy. ▪ Cryptocurrency, including Zcash (ZEC) and Bitcoin (BTC), is subject to significant legal, commercial, tax, technical and regulatory uncertainty. ▪ The concentration of our expected digital asset holdings relative to non-digital assets enhances the risks inherent in our digital asset treasury strategy. ▪ A significant decrease in the market value of our digital asset holdings could adversely affect our ability to satisfy financial obligations, including any debt financings. ▪ We may require additional capital to fund our operations and grow our business, which may not be available on acceptable terms, or at all. ▪ If we are unable to raise additional capital on acceptable terms or at all, our ability to implement our business strategy may be compromised. ▪ Financial institutions may discontinue banking services to businesses engaged in crypto-related activities. ▪ We may be unable to timely complete our strategic growth initiatives within our anticipated cost estimates. ▪ We may acquire other assets, form collaborations or make investments in other companies or technologies that could harm our operating results, dilute our stockholders' ownership, or cause us to incur significant expense. ▪ We have engaged in, and may continue to engage in, strategic acquisitions and other transactions that could disrupt our business, dilute our stockholders, increase compliance costs, strain our financial resources and harm our operating results. Our proposed business combination could disrupt our business, increase compliance costs, strain our financial resources and harm our operating results. ▪ Failure to successfully integrate businesses and assets after any strategic transactions could negatively impact our balance sheet and results of operations. ▪ Limited regulation of digital asset exchanges may expose us to negative publicity which could adversely affect an investment in us. ▪ We depend on attracting and retaining officers, managers, and skilled professionals. ▪ Global macroeconomic, geopolitical, and public health events and resulting supply chain issues could adversely affect our business, financial condition, and operations. ▪ We face risks related to technological obsolescence, vulnerability of the global supply chain for cryptocurrency, potential trade restrictions and difficulty in obtaining new hardware, which may have a material adverse effect on our business. ▪ Intellectual property disputes related to digital asset technology could threaten our ability to operate. ▪ If we are unable to protect our intellectual property rights or if our intellectual property rights are inadequate to protect our technology and product candidates, our competitive position could be harmed. ▪ We may be exposed to potential liability from claims relating to intellectual property rights. ▪ The adoption and long-term viability of digital asset networks is uncertain, and a decline in their growth or acceptance could negatively impact our business and the value of our stock. ▪ We have derived, and may continue to derive, a substantial portion of our revenues from related parties due to our participation in affiliate Foundry Digital's mining pools, which allow miners to combine their computing and processing power, reducing the variability associated with solving blocks and getting rewarded by the network. ▪ Miner delivery and infrastructure development schedules may be delayed due to constraints in the global supply chains for miners, electricity distribution equipment, and construction materials. 27 STRICTLY PRIVATE AND CONFIDENTIAL

Risk factors (3/4) Risks Related to the Market for Cryptocurrency ▪ There is a finite supply of bitcoin, and the declining block reward over time presents a risk to our business. ▪ Our success depends on external factors affecting the cryptocurrency industry. ▪ Digital asset holdings are less liquid than cash and cash equivalents and may not be able to serve as a source of liquidity for us to the same extent as cash and cash equivalents. ▪ Our ability to generate profit is largely dependent on the price of ZEC and BTC, which has historically been volatile. ▪ Exposure to financially troubled cryptocurrency companies may impact our reputation and operational profitability. ▪ Cryptocurrency faces scaling obstacles, including high transaction fees, which may adversely affect demand for cryptocurrency, our mining operations and growth. ▪ BTC and ZEC are highly volatile digital assets, and fluctuations in the price of BTC and ZEC may adversely influence our financial results and the market price of our listed securities. ▪ Our digital asset holdings expose us to market volatility and liquidity risks, which may affect our ability to effectively manage our growth plans and profitability. ▪ Regulatory, commercial, and technical uncertainties may influence cryptocurrency prices. ▪ Our digital asset management activities expose us to credit, market, liquidity and operational risks. ▪ Geopolitical and economic crises could lead to increased uncertainty, large-scale selloffs of digital assets and a decline in cryptocurrency's value, negatively impacting our business and stock price. ▪ During periods of market stress and extreme volatility, we may be unable to timely liquidate or hedge our cryptocurrency or related positions, and exchange-driven liquidations or auto-deleveraging could materially and adversely affect our liquidity, results of operations and financial condition. ▪ Incorrectly estimating our mining data center lease capacity requirements and capital expenditures could adversely affect our results of operations. ▪ Significant disruptions in the cryptocurrency markets could materially impair the value of our mining rigs, and prolonged low cryptocurrency prices could force us to idle our mining rigs. ▪ Our cryptocurrency miners may not be adaptable to other uses which could adversely affect our business and results of operations. ▪ Noise generated by our mining operations poses regulatory, legal, operational and reputational risks. ▪ Our mining operations may generate less revenue as a result of "halving". ▪ We face risks relating to the potential compromise of the Zcash, Bitcoin and other digital asset network security by emerging technologies, including artificial intelligence and quantum computing. ▪ The cryptography used on the Zcash network could fail or could be used to facilitate illicit activities, and businesses that facilitate transactions in ZEC may be at increased risk of criminal or civil lawsuits. ▪ Our ability to grow our hash rate relative to the global network hash rate and increasing network difficulty may impact our ability to effectively compete. ▪ Disruptions, forks, 51% attacks, hacks, network disruptions, or other adverse events or other compromises to blockchain networks, could materially and adversely impact us. ▪ If a security breach or cyberattack gives unauthorized parties access to our digital assets, or if our access to our wallets holding digital assets is lost or destroyed, we may lose some of, or all of our digital assets. ▪ Loss of access to our private keys or data could result in a permanent loss of our digital assets. ▪ Cyber-attacks, threats, data breaches, or malware may disrupt our operations and expose us to liability, loss of digital assets, reputational damage, and business disruptions which could harm us. ▪ The irreversibility of digital asset transactions exposes us to risks of theft, loss and human error, which could negatively impact our business. ▪ Our revenue generation is subject to risks applicable to mining pools we participate in, including risks outside of our control. ▪ We may not be able to realize the benefits of forks. ▪ We are subject to risks associated with our need for significant electrical power, including risks arising from prolonged power and internet outages, shortages or capacity constraints, which could harm our business. ▪ Certain natural disasters, mechanical failures, cyber incidents, evolving climate and ESG requirements, and other events outside of our control could adversely affect us. 28 STRICTLY PRIVATE AND CONFIDENTIAL

Risk factors (4/4) Risks Related to Governmental Regulation and Enforcement that may affect Fortitude ▪ Changes to laws, regulations, or enforcement priorities may adversely impact our cryptocurrency mining and related activities. ▪ Changes in U.S. trade policy may have a material adverse impact on our business, financial condition and operations. ▪ Our access to power is dependent on third-party providers and regulators and any adverse action by such entity may have a material adverse effect on us. ▪ We may be deemed to be a "commodity pool" under CEA and CFTC Rules as a result of our commodity interest trading. ▪ We are not subject to legal and regulatory obligations that apply to investment companies such as mutual funds and ETPs, or to obligations applicable to investment advisers. ▪ Changes in regulatory interpretations could require us to register as a money services business or money transmitter, leading to increased compliance costs or operational shutdowns. ▪ Regulatory changes may alter the nature of an investment in us or restrict the use of cryptocurrencies in a manner that adversely affects our business. ▪ Absent clearer federal regulations, there is a possibility that ZEC or BTC may be classified as a "security." Any classification of ZEC or BTC as a "security" could lead to our falling under the definition of "investment company" under the Investment Act of 1940, as amended. ▪ Our ZEC treasury strategy may subject us to enhanced regulatory oversight. ▪ We may inadvertently and without knowledge, directly or indirectly, engage in transactions in violation of U.S. or foreign sanctions laws, including as a result of our interactions with a blockchain, which may lead to regulatory penalties and reputational harm. ▪ Compliance costs of responding to new and changing regulations could adversely affect our operations and expose our business to new risks. ▪ Our expanding mining data center ownership may be subject to new or evolving regulatory frameworks. ▪ The rapidly evolving and uncertain regulatory landscape for cryptocurrencies and cryptocurrency mining exposes us to legal risks, compliance costs, and potential business disruptions. ▪ The U.S. political and economic environment could materially impact our business operations and financial performance, and uncertainty surrounding the potential legal, regulatory and policy changes by the U.S. presidential administration may directly affect us and the global economy. ▪ Operating in foreign jurisdictions could expose us to political, legal, and regulatory risks that could negatively impact our financial condition. ▪ Changing environmental, property and tax regulations and public energy policies could increase our costs and adversely affect our business. ▪ The lack of a comprehensive and uniform regulatory framework governing many bitcoin and Zcash trading venues may expose us to market structure risks, fraud, security failures and operational disruptions, which could adversely affect the value and liquidity of our bitcoin holdings. Risks Related to the Proposed Transaction ▪ Failure to complete, or delays in completing, the Proposed Transactions could materially and adversely affect our results of operations, business, financial results and/or HSCS's common stock price. ▪ If the conditions to the Proposed Transactions is not satisfied or waived, the Proposed Transactions may not occur. ▪ The issuance of HSCS's common stock to the stockholder of Fortitude and the resulting change in control must be approved by HSCS's stockholders. Failure to obtain such approval would prevent the closing of the Proposed Transaction. ▪ The Proposed Transactions may be completed even though a material adverse effect may result from the announcement of the Proposed Transactions, industry-wide changes or other causes. ▪ If the Proposed Transaction is not completed, HSCS's stock price may decline significantly. ▪ HSCS's stockholders and the stockholder of Fortitude may not realize a benefit from the Proposed Transactions commensurate with the ownership dilution they will experience in connection with the Proposed Transactions. ▪ The post-Proposed Transactions business of the combined company may not be successful. ▪ The anticipated benefits of the Proposed Transaction may fail to be realized, and the integration of our businesses may be more difficult, costly, or time-consuming than expected. 29 STRICTLY PRIVATE AND CONFIDENTIAL

Reconciliation of Forward-Looking Adjusted EBITDA to Net Income (Loss) A quantitative reconciliation of forward-looking Adjusted EBITDA to forward-looking Net Income (Loss) is not provided because certain reconciling items cannot be reasonably predicted or estimated without unreasonable effort. These items include, but are not limited to: • Impairments of goodwill, intangible assets, long-lived assets, and digital assets, which depend on future market conditions, including the price of Zcash, Bitcoin, and other digital assets; • Mark-to-market gains and losses on digital asset holdings and derivative instruments; • Realized gain/losses on sales or exchanges of digital assets • Stock-based compensation expense tied to future grants, forfeitures, and share price movement; • Transaction-related costs associated with potential acquisitions, divestitures, or capital markets activity; and • Income tax effects of the foregoing items. For similar reasons, the probable significance of such items cannot be reasonably predicted or estimated without unreasonable effort. However, the variability of the items listed above is expected to be significant and could have a material impact on GAAP Net Income (Loss). Accordingly, Fortitude's management is unable to provide a quantitative reconciliation of forward-looking Adjusted EBITDA to forward-looking Net Income (Loss) without unreasonable effort and furthermore does not believe that a GAAP reconciliation would provide meaningful supplemental information about our illustrative guidance. 33 STRICTLY PRIVATE AND CONFIDENTIAL

Calculations Underlying Presentation of Illustrative Financial Performance at Various Zcash Prices • % BTC Market Cap: Calculation reflects the circulating supply of Zcash and Bitcoin as of 4/27/26 and assumes a Bitcoin price of $75,000. • Fortitude Zcash Mined: Calculation reflects daily Zcash production of 430 coins multiplied by 365 days. Average daily Zcash production through 4/30/26 was ~430 Zcash. To maintain production levels, management estimates it will need to procure 4,000 additional Z15 Pro equivalent miners by year end, assuming a year end network hash rate of 24 GS. • Fortitude Zcash Mined Upside: Calculation reflects daily Zcash production of 500 coins multiplied by 365 days. Management estimates it will need to procure 5,500 additional Z15 Pro equivalent miners by year end to achieve this production level. • Zcash Mining Revenue: Calculation reflects Fortitude Zcash Mined multiplied by Zcash Price. • BTC Mining Revenue: Management estimate of $27.0mm relative to preliminary, unaudited YTD BTC Mining Revenue of $9.0mm as of 4/30/26. • Other Revenue: Management estimate of $1.8mm relative to preliminary, unaudited YTD Other Revenue of $0.6mm as of 4/30/26. • Gross Profit: Calculation assumes Zcash Cash COGS per coin of $70 relative to preliminary, unaudited YTD results of $71 per coin as of 4/30/26, Bitcoin gross profit margin of 4.0%, other gross profit margin of 28.3%, management estimated owned site expenses of $2mm per year and $1.7mm of annualized expenses related to Repair Expense, Machine Insurance Expense, and Corporate Insurance Expense. Bitcoin gross profit margin and other gross profit margin in line with preliminary, unaudited YTD actual results as of 4/30/26. At Zcash Cash COGS per coin of $40 rather than $70 per coin, Gross Profit would increase by approximately $5mm. • Adjusted General & Administrative Expense: In line with preliminary, unaudited YTD results of $7.8mm as of 4/30/26 adjusted to remove $2.9mm of non-recurring expenses, comprised primarily of transaction related expenses and non-recurring litigation spend presented on an annualized basis. Annualized number further adjusted to include management's estimate of $5.0mm of public company expenses relative to the annualized figure. • Further Illustrative Adjusted EBITDA: Based on mined quantities described in the Fortitude Zcash Mined Upside line above which assumes 500 Zcash mined per day. Adjusted General & Administrative Expense, Adjusted EBITDA and Adjusted EBITDA Margin are non-GAAP metrics. See the discussion of Non-GAAP measures elsewhere in the presentation, as well as elsewhere in this Appendix for a description of why a reconciliation to General & Administrative Expense or Net Income (Loss), the closest GAAP measures, as applicable, is not available for such non-GAAP guidance. 36 STRICTLY PRIVATE AND CONFIDENTIAL The following notes discuss the calculations underlying each metric appearing in the presentation of the Illustrative Financial Performance at Various Zcash Prices provided earlier in this presentation.
