1.01. Entry into a Material Definitive Agreement.

October 20, 2026, Soluna Holdings, Inc. (the “Company”) and certain affiliates thereof entered into a Subscription Agreement

(as defined and discussed in further detail below) with certain affiliates of Applied Digital Corporation,

a Nevada corporation (“Applied”), to

form a jointly owned company to develop a planned 50 megawatt Critical I.T. data center for artificial intelligence and high-performance

computing at Project Dorothy 3, the Company’s development site near Silverton (Briscoe County), Texas, and the Briscoe Wind Farm.

The

Subscription Agreement

October 20, 2026, the Company entered into a Subscription Agreement (the “Subscription Agreement”) with Soluna HPC D3 STX

HoldCo, LLC, a Delaware limited liability company and an indirect wholly

owned subsidiary of the Company (“Soluna Investor”), Soluna STX Borrower HoldCo, LLC, a Delaware limited liability company

(“Soluna STX”), APLD Intermediate HoldCo, LLC, a Delaware limited liability company and direct, wholly owned subsidiary of

Applied (“Applied Guarantor”), APLD

STX Holdings LLC,

a Delaware limited liability company and an indirect wholly

owned subsidiary of Applied (“Applied Investor”), STX JV Holdings LLC, a Delaware limited liability company and an

indirect wholly owned subsidiary of Applied (the

“Project Company”), and Soluna DV Services, LLC, a Nevada limited liability company and wholly owned subsidiary of the Company

(the “Ground Lessee”). Pursuant to the Subscription Agreement, at the closing (the “Closing”) of the transactions

contemplated by the Subscription Agreement (the “Transactions”), Soluna Investor is obligated to subscribe for and acquire

common units representing 49% of the issued and outstanding membership interests of the Project Company, and Applied Investor is obligated

to subscribe for and acquire common units representing 51% of the issued and outstanding membership interests of the Project Company.

As consideration for issuance of Project Company common units to Soluna Investor, Ground Lessee, as landlord, and STX-01 LLC,

a wholly owned subsidiary of the Project Company,

as tenant, will enter into the Ground Sublease (as defined below), with an attributed value to Soluna Investor, pursuant to the Subscription

Agreement, of $18,750,000. Additionally, Soluna STX will contribute STX JV Intermediate Holdings, LLC, a newly formed holding company

and wholly owned subsidiary of Soluna STX, to the Project Company. As consideration for issuance of Project Company common units to Applied

Investor, Applied Investor will contribute to the Project Company an amount in cash equal to $19,515,306, subject to a dollar-for-dollar

credit against such amount for amounts actually paid by Applied Investor or its affiliates prior to the Closing for certain development

work performed at the site of the Project (as defined below) or the procurement of certain long lead-time equipment on behalf of the

Project Company. Soluna Investor’s and Applied Investor’s obligations under the Subscription Agreement are guaranteed respectively

by the Company and Applied Guarantor.

The

Closing is expected to occur on or before December 1, 2026 (the “Outside Date”), subject to the satisfaction or waiver of

certain conditions set forth in the Subscription Agreement, including: (1) the absence of any law, order or injunction enacted, issued

or in effect that restrains, enjoins, prohibits or otherwise prevents the Transactions, and the absence of any action instituted or threatened

in writing by a governmental authority that would reasonably be expected to prevent or prohibit the Transactions; (2) the occurrence

of the Tax Abatement Vote (as defined in the Subscription Agreement), (3) the accuracy, as of the Closing, of the representations and

warranties made by each party in the Subscription Agreement in all respects, except for such inaccuracies as are de minimis in nature

and amount relative to the applicable representation and warranty taken as a whole; (4) the performance or compliance by each party,

in all material respects, with all obligations and covenants required to be performed or complied with by it at or prior to the Closing;

(5) the negotiation, execution and delivery by each party thereto of the agreements and other documents required to be executed and delivered

at or prior to the Closing, including the LLC Agreement (defined below) and the Ancillary Agreements (as defined below) (collectively,

the “Transaction Documents”); (6) the requisite internal approvals by ChronoScale Holdings Corporation,

a Nevada corporation (“ChronoScale”), and

its applicable affiliate of the Data Center Lease (as defined below); (7) the requisite internal approvals by Applied, the Company and

each of their applicable affiliates of the Transaction Documents (including the LLC Agreement and the Ancillary Agreements); and (8)

the issuance of the Leasehold Title Policy (as defined in the Subscription Agreement) by the applicable title company. Either Soluna

Investor or Applied Investor may terminate the Subscription Agreement if the Closing has not occurred on or before the Outside Date,

except that if, as of such date, all conditions to the Closing have been satisfied or waived (other than those conditions that by their

nature are to be satisfied at the Closing and are then capable of being satisfied) other than the condition relating to (i) the Tax Abatement

Vote, then the Outside Date will automatically be extended, for one time only, by thirty (30) days, or (ii) the issuance of the Leasehold

Title Policy or delivery of Title Deliverables, then the Outside Date will automatically be extended, for one time only, by ten (10)

days, but in no event will the Outside Date extend beyond December 31, 2026.

of the date of this Current Report Form

8-K, certain development work related to the Project has begun at the site of the Project and will continue through the Closing, and

certain equipment necessary for the development of the Project may be procured, in each case, at the costs and expense of Applied (collectively,

the “Funded Costs”). If the Closing fails to occur and the Subscription Agreement is terminated, Soluna

Investor will be obligated to reimburse Applied

Investor for

eighty percent (80%) of such Funded Costs, up to a maximum of $45 million, subject to a reimbursement schedule and interest as specified

in the Subscription Agreement, which obligation is guaranteed by the Company.

The

LLC Agreement

connection with the Subscription Agreement and the Transactions, at Closing, Soluna Investor and Applied Investor will also enter into

an Amended and Restated Limited Liability Company Agreement of the Project Company (the “LLC Agreement”), setting forth the

terms and conditions of the ownership, management and operation of the Project Company. The purpose of the Project Company is to, among

other things, acquire, own, construct, develop, operate, manage, lease and monetize the initial phase of a data center facility known

as “Dorothy 3A,” consisting of approximately 75 megawatts of gross capacity, or 50 megawatts of Critical I.T. capacity, in

Briscoe County, Texas (the “Project”). The LLC Agreement is expected to

contain customary representations and warranties of the parties

thereto. The terms of the LLC Agreement, when finalized, may differ from those currently contemplated by the Subscription Agreement.

The

Lease Agreements

connection with the Subscription Agreement, the LLC Agreement and the Transactions,

at Closing, the Ground Lessee will enter into a 99-year Ground Sublease Agreement (the “Ground Sublease”) with STX-01 LLC,

a wholly-owned subsidiary of the Project Company (“Tenant”), pursuant to which Tenant will lease from the Ground Lessee,

all right, title and interest of Ground Lessee in the land leased under that certain Ground Lease to be entered into between Soluna Dorothy

3 Energy ServiceCo, LLC and Soluna DV BNSF Energy HoldCo, LLC (collectively, the “Fee Owner”), as landlords, and the Ground

Lessee, as tenant, covering certain real property located in Briscoe County, Texas (the “Fee Ground Lease”), upon which the

Project will be developed. The terms of the Ground Sublease and the Fee Ground Lease, when finalized, may differ from those currently

contemplated by the Subscription Agreement.

The

Warrant

The

Subscription Agreement contemplates that, at the Closing, the Company will issue to Applied or an affiliate thereof (the “Holder”)

in a private placement (“Private Placement”), a Common Stock Purchase Warrant (the “Warrant”) to purchase up

to 7,644,444 shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), at an exercise

price of $0.74 per share. The Warrant is anticipated to be exercisable at any time on or after the issue date and on or prior to the

seven-year anniversary thereof. The Warrant is anticipated to be subject to adjustment in the event of certain stock dividends and distributions,

stock splits, stock combinations, reclassifications or similar events affecting the Common Stock. In the event of certain corporate transactions,

the Holder is anticipated to be entitled to receive, upon exercise of the Warrant, the kind and amount of securities, cash or other property

that the holders would have received had they exercised the Warrant immediately prior to such transaction. The

Holder is expected to agree that, for the period beginning on the issue date and ending on the earlier of the twelve-month anniversary

thereof and the date on which the volume weighted average price of the Common Stock equals or exceeds $10.00 per share, it will not,

directly or indirectly, engage in any short sale of the Common Stock or otherwise hedge its economic exposure to the Common Stock.

The Warrant is not expected to entitle the holders thereof

to any voting rights or any of the other rights or privileges to which holders of Common Stock are entitled. The Warrant is expected

to be issued and sold without registration under the Securities Act of 1933, as amended (the “Securities Act”), or state

securities laws in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act promulgated thereunder and in reliance

on similar exemptions under applicable state laws.

The

form of the Warrant has not been finalized as of the date of this Current Report Form

8-K, and the issuance of the Warrant is conditioned upon the occurrence of the Closing.

The

Registration Rights Agreement

The

Subscription Agreement contemplates that, at the Closing, the Company will enter into a Registration Rights Agreement (the “Registration

Rights Agreement”) with the Holder, pursuant to which the Company would agree to file a registration statement with the Securities

and Exchange Commission (the “SEC”) to

register the resale or other disposition of the Warrant and the shares of Common Stock issuable upon exercise of the Warrant (together,

the “Registrable Securities”). It is expected that the Company will be required to prepare and file a registration statement

with the SEC on or prior to 30

days following the Closing (the

“Filing Deadline”), and to have the registration statement declared effective as soon

as reasonably practicable but in no event later than 30

days of the Filing Deadline if the SEC does not review such registration statement. It is expected that the Company will also be required

to use its commercially reasonable efforts

to keep any such registration statement continuously effective until (i) the date that all of the Registrable Securities have been publicly

sold by the Holder, (ii) the date that all of the Registrable Securities have been previously sold in accordance with Rule 144 or (iii)

such time as all of such Registrable Securities may be sold by the Holder without any restriction pursuant to Rule 144, including holding

period, volume or manner-of-sale restrictions pursuant to Rule 144 and without the requirement for the Company to be in compliance with

the current public information requirement under Rule 144.

The

form of the Registration Rights Agreement has not been finalized as of the date of this Current Report

Form 8-K, and entry into the Registration Rights Agreement

is conditioned upon the occurrence of the Closing.

The

Ancillary Agreements

The

Subscription Agreement contemplates that, at or prior to the Closing, the parties, certain of their respective affiliates and certain

third parties will enter into a number of additional agreements (the “Ancillary Agreements”) as set forth in the Subscription

Agreement, including (i) the Fee Ground Lease, (ii) the Ground Sublease, (iii) a data center lease between Tenant, as landlord, and ChronoScale

or an affiliate thereof, as tenant, (the “Data Center Lease”), (iv) an engineering, procurement and construction contract

relating to the Project, (v) certain shared services agreements among the parties, (vi) assignment and assumption agreements with respect

to certain contracts relating to the Project, (vii) the Warrant, and (viii) the Registration Rights Agreement. Other than the form of

assignment and assumption agreement, the forms of the Ancillary Agreements have not been finalized as of the date of this Current

Report Form 8-K. During the period from the date

of the Subscription Agreement until the earlier of the Closing and the termination of the Subscription Agreement (the “Interim

Period”), the parties have agreed to use commercially reasonable efforts to negotiate in good faith to finalize the Ancillary Agreements.

The execution and delivery of the Ancillary Agreements in form and substance reasonably acceptable to the parties thereto, Soluna Investor

and Applied Investor and the requisite internal approvals by Applied, the Company and each of their applicable affiliates

of the Transaction Documents (including the LLC Agreement and the Ancillary Agreements) are conditions to each party’s obligation

to consummate the Closing, and the requisite internal approvals by ChronoScale and its applicable

affiliate are a condition to the obligations of Applied Investor and Applied Guarantor to consummate the Closing. If the

parties are unable to agree upon final forms of the Ancillary Agreements, the Closing may not occur. The terms of the Ancillary Agreements

and LLC Agreement, when finalized, may differ from those currently contemplated by the Subscription Agreement.

REPRESENTATIONS

AND WARRANTIES OF THE SAIL INVESTOR, STX HoldCo AND THE GROUND LESSEE

The

Sail Investor, the Ground Lessee and STX HoldCo, as applicable, severally and not jointly, hereby represent and warrant to the

Company and the Anchor Investor that the following representations are true, correct and complete:

Section

3.1 Investment.

(a)

The Sail Investor is acquiring its Interests for investment and for the Sail Investor’s own account, not as a nominee or agent,

and not with a view to, or with the intent to, resell or distribute any part thereof. The Sail Investor has no present intention of selling,

granting any direct participation in, or otherwise distributing the same. By executing this Agreement, the Sail Investor further represents

that the Sail Investor does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer

or grant participations to such Person or to any third Person, with respect to any of its Interests.

(b)

The Sail Investor understands that (i) the offering and issuance of its Interests hereby are intended to be exempt from registration

under the Securities Act and all applicable state and foreign securities laws, (ii) the offering and issuance of its Interests have not

been registered under the Securities Act or any applicable state or foreign securities laws, and the Company has made no assurances that

its Interests will be registered under the Securities Act or any applicable state or foreign securities laws, and, therefore, its Interests

cannot be sold, transferred or otherwise disposed of unless such sale, transfer or other disposition is registered under the Securities

Act and all applicable state and foreign securities laws or an exemption from such registration is available, (iii) the sale, transfer

or other disposition of its Interests will be restricted by the terms of the Operating Agreement, (iv) there can be no assurance the

Sail Investor will be able to sell, transfer or dispose of its Interests, (v) its Interests are “restricted securities” under

applicable federal, state or foreign securities laws and that, pursuant to these laws, the Sail Investor may be required to hold its

Interests indefinitely and the Sail Investor may be required to continue to bear the economic risk of complete loss of investment in

its Interests unless and until they are registered and qualified, or an exemption from such registration and qualification requirements

is available, (vi) the Company has no obligation to register or qualify its Interests for resale under this Agreement and the Transaction

Documents, and (vii) if an exemption from registration or qualification is available, it may be conditioned on various requirements including,

but not limited to, the time and manner of sale, the holding period for its Interests, and on requirements relating to the Company which

are outside of the Sail Investor’s control, and which the Company may not be able to satisfy.

(c)

The Sail Investor’s financial situation is such that the Sail Investor can afford to bear the economic risk of holding its Interests

acquired hereunder for an indefinite period of time, and the Sail Investor can afford to suffer the complete loss of the investment in

its Interests.

(d)

The Sail Investor’s knowledge and experience in financial and business matters are such that the Sail Investor is capable of evaluating

the merits and risks of the investment in its Interests, or the Sail Investor has been advised by a representative possessing such knowledge

and experience.

(e)

The Sail Investor understands that its Interests acquired hereunder are a speculative investment which involves a high degree of risk

of loss of the entire investment therein, that there are, or will be, substantial restrictions on the transferability of its Interests

under Applicable Law and as set forth in the Operating Agreement to which the Sail Investor shall be a party, and that for an indefinite

period following the Closing Date there will be no public market for its Interests and that, accordingly, it may not be possible for

the Sail Investor to sell its Interests in case of emergency or otherwise. The Sail Investor understands that the Company has made no

assurances that a public market will ever exist for its Interests.

(f)

The Sail Investor and the Sail Investor’s Representatives have been given the opportunity to examine documents and to ask questions

of, and to receive answers from, the Company and its Affiliates and Representatives concerning the terms and conditions of the acquisition

of its Interests and related matters and to obtain all additional information which the Sail Investor and the Sail Investor’s Representatives

deem necessary. The Sail Investor has conducted its own independent review and analysis of the Company, its Interests, the Operating

Agreement and the transactions contemplated by the Transaction Documents and has not relied on, and is not relying on, any statement,

information, projection, forecast or representation or warranty of any nature, express or implied, made or purported to be made by or

on behalf of the Company or any of its Affiliates or Representatives, except as expressly set forth in this Agreement (as qualified by

the Disclosure Schedule), the Transaction Documents and any certificate delivered in connection therewith.

(g)

The Sail Investor is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities

Act. The Sail Investor has such knowledge and experience in financial and business matters such that the Sail Investor is capable of

evaluating the merits and risks of the acquisition of its Interests and an investment in the Company. The Sail Investor is not subject

and complete:

Section

4.1 Investment.

(a)

The Anchor Investor is acquiring its Interests for investment and for the Anchor Investor’s own account, not as a nominee or agent,

and not with a view to, or with the intent to, resell or distribute any part thereof. The Anchor Investor has no present intention of

selling, granting any direct participation in, or otherwise distributing the same. By executing this Agreement, the Anchor Investor further

represents that the Anchor Investor does not presently have any contract, undertaking, agreement or arrangement with any Person to sell,

transfer or grant participations to such Person or to any third Person, with respect to any of its Interests.

(b)

The Anchor Investor understands that (i) the offering and issuance of its Interests hereby are intended to be exempt from registration

under the Securities Act and all applicable state and foreign securities laws, (ii) the offering and issuance of its Interests have not

been registered under the Securities Act or any applicable state or foreign securities laws, and the Company has made no assurances that

its Interests will be registered under the Securities Act or any applicable state or foreign securities laws, and, therefore, its Interests

cannot be sold, transferred or otherwise disposed of unless such sale, transfer or other disposition is registered under the Securities

Act and all applicable state and foreign securities laws or an exemption from such registration is available, (iii) the sale, transfer

or other disposition of its Interests will be restricted by the terms of the Operating Agreement, (iv) there can be no assurance the

Anchor Investor will be able to sell, transfer or dispose of its Interests, (v) its Interests are “restricted securities”

under applicable federal, state or foreign securities laws and that, pursuant to these laws, the Anchor Investor may be required to hold

its Interests indefinitely and the Anchor Investor may be required to continue to bear the economic risk of complete loss of investment

in its Interests unless and until they are registered and qualified, or an exemption from such registration and qualification requirements

is available, (vi) the Company has no obligation to register or qualify its Interests for resale under this Agreement and the Transaction

Documents, and (vii) if an exemption from registration or qualification is available, it may be conditioned on various requirements including,

evaluating the merits and risks of the investment in its Interests, or the Anchor Investor has been advised by a representative possessing

of loss of the entire investment therein, that there are, or will be, substantial restrictions on the transferability of its Interests

under Applicable Law and as set forth in the Operating Agreement to which the Anchor Investor shall be a party, and that for an indefinite

period following the Closing Date there will be no public market for its Interests and that, accordingly, it may not be possible for

the Anchor Investor to sell its Interests in case of emergency or otherwise. The Anchor Investor understands that the Company has made

no assurances that a public market will ever exist for its Interests.

(f)

The Anchor Investor and the Anchor Investor’s Representatives have been given the opportunity to examine documents and to ask questions

efforts to take all actions, and do, or cause to be done, all things necessary, proper, or advisable under any Applicable Laws to consummate

the Closing and the transactions contemplated hereby. Prior to the Closing, the Anchor Investor shall keep the Sail Investor reasonably

informed as to the status of the Project Financing and provide the Sail Investor with the consultation rights set forth in Section

8.3(b). Notwithstanding anything to the contrary in this Agreement, (i) the “commercially reasonable efforts” standard

set forth in this Section 8.3 shall not in any event be construed to require any Party or any of its Affiliates or its or their

direct or indirect equityholders to take or commit to take any action that limits in any respect such Party’s freedom of action

with respect to, or its ability to retain, any business, products, rights, services, licenses, assets or properties of such Party or

any of its equityholders or its or their respective Affiliates and (ii) in no event shall any Party or any of its Affiliates be required

by a Governmental Authority to agree to take, or enter into any action, which action is not conditioned upon the Closing.

(b)

During the Interim Period, the Anchor Investor shall be responsible for arranging the Project Financing (as defined herein), and shall

have authority to determine the terms and conditions thereof; provided, however, that the Anchor Investor shall use commercially

reasonable efforts to (i) consult with the Sail Investor regarding the material terms of any proposed Project Financing and consider

the Sail Investor’s feedback thereto (including any proposed comments to the definitive documentation for the Project Financing

and any other related documentation), (ii) promptly share each material “turn” of the draft definitive documentation for

the Project Financing with the Sail Investor and (iii) hold regular meetings of a designee of the Anchor Investor (which may be the Chief

Financial Officer of the Anchor Investor or any other officer or employee of the Anchor Investor or its Affiliates designated by the

Chief Executive Officer or Chief Financial Officer of the Anchor Investor), and designees of the Sail Investor, at such intervals as

are mutually agreed by the Anchor Investor and the Sail Investor, to discuss the status, progress and relevant details regarding the

Project Financing. Notwithstanding anything to the contrary in this Agreement, (x) the failure of the Anchor Investor to comply with

the foregoing consultation provisions shall not affect the validity or enforceability of any Project Financing and (y) neither the Sail

Investor nor any of its Affiliates shall be required to enter into, execute, deliver, or become a party to any definitive documentation

for the Project Financing or any guaranty or other credit support arrangement in connection with any Project Financing. For the avoidance

of doubt, under no circumstances, including the failure of the Anchor Investor to arrange or obtain the Project Financing, shall the

Anchor Investor or any of its Affiliates be responsible in any way for providing, investing in, making capital contributions for, or

otherwise funding, any of the Project Financing. For purposes of this Section 8.3(b), “Project Financing” shall

mean any debt financing for the Company or any of its Subsidiaries with respect to the development, construction or operation of the

Project, including any construction loan, term loan or other credit facility, any financing for long-lead equipment, and any refinancing,

replacement, extension or amendment of any of the foregoing, in each case that is non-recourse to any direct or indirect owner of the

Company or its applicable Subsidiaries (other than with respect to customary pledges of equity interests in the borrower of such debt

financing, and any completion guaranty to be provided by Anchor TopCo).

Section

8.4 Right to Access the Land and Develop the Project. During the Interim Period, the Fee Owner shall permit the Anchor Guarantor

and its Subsidiaries (including the Anchor Investor, the Company and JV Entity Propco) and the Anchor Representatives to enter upon the

Land to design, engineer, permit and prepare the site for construction of the Project (collectively, the “Activities”)

which include: (A) non-invasive site work, consisting solely of design, engineering, permitting, surveys, geotechnical investigations,

and staking, in each case in connection with the Project; and (B) concrete foundation and slab work for the Project, but only to the

extent such work is within the scope of a written authorization issued by the Fee Owner (an “Authorization”), provided

that Anchor Guarantor shall provide Fee Owner and Fee Owner’s general manager with reasonable prior written notice (e-mail being

sufficient for this purpose) before commencing each major milestone of development of the Project. In each case, the Activities are subject

to the following limitations:

(a)

The Anchor Guarantor shall obtain, or cause to be obtained, insurance coverages in such amounts, with such deductibles and covering such

risks as are customarily maintained by prudent developers of projects of a similar size, type and geography as the Project, and otherwise

in form and substance reasonably satisfactory to the Sail Investor (the “Required Insurance”), which obligation may

be satisfied, in whole or in part, through insurance maintained by the Anchor Guarantor, any of its Affiliates or any of its or their

contractors (including Hypergate and its insurance programs). (i) No later than three (3) Business Days following the date of this Agreement,

the Anchor Investor shall deliver, or cause to be delivered, to the Sail Investor a schedule setting forth the Required Insurance for

approval by the Sail Investor (the “Insurance Schedule”); and (ii) no later than ten (10) Business Days following

the date of this Agreement, the Anchor Guarantor shall obtain, or cause to be obtained, the certificates of insurance for the applicable

Required Insurance and shall cause the Sail Investor (or its applicable Affiliates) to be added to the applicable Required Insurance

as additional insured (clauses (i) and (ii), collectively, the “Insurance Requirements”). Notwithstanding anything

to the contrary herein, in the event that the Anchor Guarantor fails to comply with any portion of the Insurance Requirements (including

the failure to meet a deadline therein or deliver a schedule setting forth the Required Insurance in form and substance reasonably satisfactory

to the Sail Investor), the Sail Investor shall have a right, as its sole and exclusive remedy (exercisable within the earlier of (x)

three (3) Business Days after receipt of the Insurance Schedule, and (y) thirteen (13) Business Days after the date of this Agreement),

with respect to such failure to comply with the Insurance Requirements, to terminate this Agreement pursuant to Section 10.1(d)

(after giving effect to the applicable notice and cure periods therein).

(b)

Subject to Section 8.6, all Activities shall be at the Anchor Guarantor’s (or the Anchor Investor’s) sole expense

and shall be conducted in accordance with applicable laws and regulations, including, without limitation, laws relating to worker safety,

environmental protection, construction, and the proper disposal of discarded materials. The Anchor Guarantor and the Anchor Investor

shall be exclusively responsible for paying all inspection fees, appraisal fees, engineering fees, construction fees, and other expenses

of any kind or nature whatsoever incurred by any Anchor Representatives relating to the Activities. All such amounts that are actually

paid by the Anchor Guarantor or its Affiliates at any time prior to the Closing or the date of termination of this Agreement pursuant

to Section 10.1, as applicable, and whether or not incurred prior to the date of this Agreement, are referred to herein as “Funded

Costs”.

(c)

The Anchor Guarantor shall, or shall cause the Anchor Investor to, promptly repair, at the Anchor Guarantor’s sole cost and expense,

any physical damage to (i) any portion of the Land outside the scope of the approved plans for the Project, or (ii) any adjacent property,

utilities or infrastructure, in each case to the extent caused by the Anchor Guarantor or Anchor Representatives in connection with the

Activities, and shall restore the affected area to a condition substantially similar to, or no less favorable than, its condition prior

to such damage.

(d)

The Anchor Guarantor shall not permit any mechanic’s or materialmen’s liens or any other liens to attach to the Land by reason

of the performance of, or in connection with, any Activities conducted by or on behalf of the Anchor Guarantor or any Anchor Representative.

If any such liens attach to the Land, the Anchor Guarantor shall, within twenty (20) days after receiving written notice or actual knowledge

thereof, whichever is first, from the Fee Owner, either (i) cause such lien to be released and discharged of record by payment or otherwise,

or (ii) cause such lien to be bonded over or otherwise removed as an encumbrance against the Land by the filing of a bond to indemnify

against the lien or other security permitted under Applicable Law, or provide the Fee Owner with other reasonable security, in each case

in an amount and form sufficient to prevent any foreclosure of such lien against the Land. So long as the Anchor Guarantor has timely

obtained and maintains such bond or other security, the Anchor Guarantor may contest the validity or amount of such lien in good faith

by appropriate proceedings, shall not be required to obtain a release of the underlying claim during the pendency of such contest, and

shall not be in default hereunder by reason of such lien. Nothing herein shall limit Anchor Guarantor’s rights under Chapter 53

of the Texas Property Code to remove, discharge or indemnify against any such lien by any means permitted thereunder. If the Anchor Guarantor

fails to timely take either of the actions described in clause (i) or (ii) above, the Fee Owner shall have the right, but

not the obligation, to expend such sums as are necessary to satisfy and remove of record such lien, and the Anchor Guarantor shall reimburse

the Fee Owner for all reasonable out-of-pocket costs, expenses and other amounts incurred by the Fee Owner in satisfying and removing

of record any such lien promptly upon written demand accompanied by reasonable supporting documentation. The provisions of this paragraph

shall survive the termination of this Agreement.

(e)

Neither the Anchor Guarantor nor any Anchor Representative shall, without the prior written consent of the Fee Owner (which consent may

be withheld in the Fee Owner’s sole and absolute discretion), undertake any activity on the Land that requires a permit, license

or other authorization under Applicable Law unless the Anchor Guarantor or the applicable Anchor Representative has obtained such permit,

license or other authorization and the same is in full force and effect (any such activities, collectively, the “Restricted

Activities”).

Section

8.5 Indemnity. Anchor Guarantor hereby agrees to indemnify, defend and hold harmless Fee Owner from and against any and all

actual out-of-pocket losses, costs, damages, claims, liabilities, expenses, demands or obligations of any kind or nature whatsoever,

to the extent actually incurred by Fee Owner (including reasonable attorneys’ fees, court costs, expenses and disbursements) (collectively,

“Claims”) arising out of or relating to any liens filed against the Land and the cost of contesting and removing the

same, or any repair or restoration of the Land required as a result of the Activities to the extent directly resulting from the performance

of the Activities by Anchor Guarantor or any Anchor Representative during the Interim Period; provided, however, that Anchor

Guarantor shall not be obligated to indemnify, defend or hold harmless Fee Owner for any Claims to the extent arising out of or resulting

from (a) the negligence or willful misconduct of Fee Owner, Ground Lessee or any of their respective Affiliates or Representatives, (b)

any breach by Fee Owner of its obligations under this Agreement, or (c) any acts or omissions occurring after the expiration of the Interim

Period.

Section

8.6 Funded Costs. Notwithstanding anything to the contrary in this Agreement, if the Closing occurs, the Anchor Investor shall

receive at the Closing a dollar-for-dollar credit against its required Subscription Amount set forth on Exhibit A in an amount

equal to the aggregate Funded Costs, including all amounts paid (i) to Hypergate or any of its contractors, subcontractors or suppliers

of any tier for development work actually performed at the Land within the scope of a written site work authorization issued by the Fee

Owner or its Affiliates or (ii) pursuant to a Master Services Agreement (the “FlexGen Master Services Agreement”)

and the related purchase orders with FlexGen Power Systems, LLC or any affiliates thereof to be entered into prior to the Closing in

respect of certain medium-voltage equipment in accordance with order specifications approved by the Sail Investor; provided, that,

the Investors shall have no obligation to enter into, incur costs related to, or otherwise pay for, the FlexGen Master Services Agreement

prior to Closing; provided, further, that (a) if the Funded Costs to be credited hereunder exceed the Anchor Investor’s

Subscription Amount set forth on Exhibit A, the Anchor Investor will receive a dollar for dollar credit against future required

contribution amounts in accordance with the provisions of the Operating Agreement, and (b) if this Agreement is validly terminated pursuant

to Section 10.1 in accordance with Section 10.2(a), following such termination, the Anchor Investor shall deliver to the

Sail Investor a Funded Costs Statement, and the Sail Investor shall reimburse, or cause to be reimbursed, in cash, the Anchor Investor

for eighty percent (80%) of the Funded Costs set forth therein, as reasonably documented by the Anchor Investor, with such reimbursement

amount not exceeding Forty-Five Million Dollars ($45,000,000) (the “Funded Costs Reimbursement Amount”) and the Anchor

Investor shall forfeit the balance of the Funded Costs and shall have no right to reimbursement, restitution, refund or credit of such

balance of the Funded Costs from the Company, the Sail Investor, the Fee Owner, the Ground Lessee, the Sail Guarantor or any of their

respective Affiliates. The Sail Investor shall reimburse, or cause to be reimbursed, the Anchor Investor in cash, (x) forty-nine percent

(49%) of the Funded Costs Reimbursement Amount within ten (10) Business Days of such termination, and (y) the remaining thirty-one percent

(31%) of the Funded Costs Reimbursement Amount within one hundred twenty (120) days of such termination, in each case of clauses (x)

and (y), together with interest at the rate of SOFR plus seven percent (7.00%) per annum, accruing from the date such Funded Cost was

incurred.

Section

8.7 Title, Survey and Zoning Due Diligence.

(a)

Access and Due Diligence. During the Interim Period, the Sail Parties shall, and shall cause the Fee Owner and their other respective

Affiliates to, afford the Anchor Investor, the Anchor Guarantor and the Anchor Representatives (i) reasonable access to the Land, upon

reasonable prior notice (email being sufficient), for the purpose of conducting such title, survey, environmental, geotechnical, zoning

and other inspections, studies, tests and investigations as the Anchor Investor determines to be necessary or appropriate in connection

with the Project (collectively, the “Diligence Investigations”), and (ii) access to all title commitments, title policies,

surveys, zoning reports, permits, environmental and geotechnical reports, and other documents and information in the possession or control

of any Sail Party, the Fee Owner or any of their respective Affiliates relating to the Land, the Fee Ground Lease or the Ground Sublease.

The Diligence Investigations shall be conducted in accordance with Section 8.4(b) through Section 8.4(d), mutatis mutandis,

and shall not constitute Restricted Activities for purposes of Section 8.4(e); provided that no invasive environmental testing

shall be conducted without the prior written consent of the Fee Owner (such consent not to be unreasonably withheld, conditioned or delayed).

(b)

Leasehold Title Policy. The Anchor Investor shall have the right to cause JV Entity Propco to obtain, effective as of the Closing,

from a nationally recognized title insurance company selected by the Anchor Investor (the “Title Company”), a leasehold

owner’s policy of title insurance insuring JV Entity Propco’s subleasehold estate in the Land under the Ground Sublease (and

the Ground Lessee’s leasehold estate under the Fee Ground Lease, to the extent required to support such coverage), in such amount

and with such endorsements as may be available in the state of Texas (including, to the extent available, a non-imputation endorsement)

and affirmative coverages as the Anchor Investor may reasonably require (the “Leasehold Title Policy”). If any title

commitment or survey received by the Anchor Investor after the date hereof discloses any title exception which was not a Permitted Exception

and such title exception was not caused by or on behalf of the Anchor Investor, the Anchor Investor may deliver to the Sail Investor,

within five (5) Business Days of the Anchor Investor’s receipt of the title commitment and applicable survey, written notice of

any objection to any matter disclosed by any title commitment, survey or update thereof for the Land (each, a “Title Objection”),

and the Sail Parties shall, and shall cause the Fee Owner and their other respective Affiliates to, use commercially reasonable efforts

to cure or remove each Title Objection to the reasonable satisfaction of the Anchor Investor and the Title Company at or prior to the

Closing; provided that, notwithstanding the foregoing, the Sail Parties shall, and shall cause the Fee Owner to, cause to be released

and discharged of record at or prior to the Closing any Lien (other than Permitted Liens) securing the payment of money that was created,

assumed or suffered by any Sail Party, the Fee Owner or any of their respective Affiliates. Should the Anchor Investor fail to timely

deliver to Fee Owner a Title Objection, the Anchor Investor shall be deemed to have approved such matters and such matters shall be deemed

to be Permitted Exceptions. If the Anchor Investor timely provides a Title Objection to Sail Investor, Sail Investor may elect, by providing

written notice (the “New Title and Survey Election Notice”) to the Anchor Investor on or prior to 6:00 p.m. (Eastern

Time) on the day that is five (5) Business Days after Sail Investor’s receipt of such Title Objection to the Anchor Investor of

whether or not it intends to cure or cause the cure of the title commitment and survey matters subject to the Title Objection. If Sail

Investor elects in the New Title and Survey Election Notice to remove or cure any matter subject to a Title Objection, Sail Investor

shall have the right to adjourn the Closing one or more times for a period not to exceed thirty (30) days in the aggregate for the purpose

of effecting such removal or cure (and the date then scheduled for the Closing shall be extended accordingly). If Sail Investor does

not provide a New Title and Survey Election Notice to the Anchor Investor within such five (5) Business Day period, then Sail Investor

shall be deemed to have elected not to remove or cure such matters subject to the Title Objection. If Sail Investor elects or is deemed

to have elected not to remove or cure such matters subject to the Title Objection, then the Anchor Investor shall have the right, as

its sole and exclusive remedy with respect to such election (or deemed election) of Sail Investor, to terminate this Agreement pursuant

to Section 10.1(e).

(c)

Cooperation; Non-Imputation Affidavit. During the Interim Period, the Sail Parties shall, and shall cause the Fee Owner and their

other respective Affiliates to, cooperate in good faith with the Anchor Investor, the Anchor Guarantor, JV Entity Propco and the Anchor

Representatives in connection with the Diligence Investigations, the issuance of the Leasehold Title Policy and the Zoning Diligence,

including by (i) executing and delivering to the Title Company at or prior to the Closing (A) a customary non-imputation affidavit, in

form and substance reasonably acceptable to the Title Company, as may be required by the Title Company as a condition to issuing a non-imputation

endorsement to the Leasehold Title Policy (the “Non-Imputation Affidavit”) (provided, however, that the Non-Imputation

Affidavit shall not cover any matters caused by the Anchor Investor or its contractors (including Hypergate and its subcontractors),

and (B) such owner’s affidavits, gap indemnities, evidence of authority, estoppel certificates and recordable memoranda of the

Fee Ground Lease and the Ground Sublease as the Title Company may reasonably require to issue the Leasehold Title Policy (together with

the Non-Imputation Affidavit, the “Title Deliverables”); and (ii) in connection with the Anchor Investor’s review

of the zoning, land use, subdivision, platting, permitting and entitlement status of the Land and the Project (the “Zoning Diligence”),

(A) executing and delivering such applications, owner authorizations, consents and letters of authorization as the Anchor Investor may

reasonably request, and (B) requesting from the applicable Governmental Authority such zoning verification letters, to the extent available

in the applicable jurisdiction, and other written confirmations as the Anchor Investor may reasonably request.

(d)

Costs. All reasonable and documented out-of-pocket costs of the Diligence Investigations, the Leasehold Title Policy and the Zoning

Diligence incurred by the Anchor Investor or its Affiliates shall constitute Transaction Costs and shall be reimbursed in accordance

with Section 12.8. Notwithstanding the foregoing, the costs of curing or removing any Title Objection or any Lien (except for

any Permitted Lien) described in the proviso to Section 8.7(b) shall be borne by the Sail Parties.

papers and take such further actions as may be reasonably required or desirable to carry out the provisions hereof and the transactions

contemplated hereby and to implement the intent of the Parties; provided, however, in no event shall the foregoing require

any Party to register any equity interests (including the Interests) or any other security of the Company under the Securities Act or

any similar or corresponding state or foreign law, rule or regulation.

Section

12.2 Non-Recourse. Notwithstanding anything to the contrary in this Agreement, (a) this Agreement may only be enforced against,

and all legal proceedings (whether in contract or in tort, in law or in equity) that may be based upon, arise out of or relate to this

this Agreement or any representation or warranty made in, in connection with, or as an inducement to this Agreement.

Section

12.3 Construction. The Parties agree that this Agreement is the product of negotiations between sophisticated Persons, each

of whom was represented by counsel, and each of whom had an opportunity to participate in, and did participate in, the drafting of each

provision hereof. Accordingly, ambiguities in this Agreement, if any, shall not be construed strictly or in favor of or against any Party

but rather shall be given a fair and reasonable construction without regard to the rule of contra proferentem. All pronouns and any variations

thereof refer to the masculine, feminine or neuter, singular or plural, as the context may require. When a reference is made in this

Agreement to a Section, Article, Exhibit or Schedule, such reference shall be to a Section or Article of, or an Exhibit or Schedule to,

this Agreement unless otherwise indicated. For all purposes hereof, the terms “include”, “includes” and “including”

shall be deemed to be followed by the words “without limitation”. Use of the terms “herein,” “hereunder,”

“hereof,” “hereby” and like terms shall be deemed to refer to this entire Agreement and not merely to the particular

provision in which the term is contained, unless the context clearly indicates otherwise. The word “or” is not exclusive.

The word “any” means “any and all”. The phrases “written notice” or “in writing” or words

of similar import shall be deemed satisfied if such notice is delivered by email; provided that no delivery failure message is

received by sender. The definitions given for any defined terms in this Agreement shall apply equally to both the singular and plural

forms of the terms defined. All references to “$” or “dollars” refer to United States dollars, and “U.S.”

or “United States” means the United States of America.

Section

12.4 Governing Law; Jurisdiction; Venue. This Agreement and all matters arising hereunder or with respect hereto, including

tort claims (the “Covered Matters”) shall be governed by, and construed in accordance with, the internal laws of the

State of Delaware, without reference to the choice of law principles thereof. Each of the parties hereto irrevocably submits to the exclusive

jurisdiction of the federal and state courts located in the State of Delaware for the purpose of any suit, action, proceeding or judgment

relating to or arising out of the Covered Matters. Service of process in connection with any such suit, action or proceeding may be served

on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each

of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying

of venue in such court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action, or proceeding

brought in such courts and irrevocably waives any claim that any such suit, action, or proceeding brought in any such court has been

brought in an inconvenient forum.

Section

12.5 Waiver of Jury Trial. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT CANNOT BE WAIVED, EACH PARTY HEREBY WAIVES,

AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT

OF ANY ISSUE, CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING IN WHOLE OR IN PART UNDER, RELATED TO, BASED ON OR IN CONNECTION WITH

THIS AGREEMENT OR THE SUBJECT MATTER HEREOF, WHETHER NOW EXISTING OR HEREAFTER ARISING AND WHETHER SOUNDING IN TORT OR CONTRACT OR OTHERWISE.

ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 12.5 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT

OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.

(a)

No public announcement or press release in connection with the execution and delivery of this Agreement, the Closing or any other subject

matter of this Agreement by the Parties in connection herewith shall be made or issued by or on behalf of any party without the prior

written approval of the Anchor Investor and the Sail Investor, which approval shall not be unreasonably withheld, conditioned, or delayed,

except (i) as may be required by Applicable Law or obligations under any listing agreement with or rules of any national securities exchange,

(ii) for such press releases or public announcements that use statements that previously have been made publicly, and (iii) as provided

in Section 12.9(b).

(b)

Notwithstanding Section 12.9(a), if a Party or any of its Affiliates is required to make or issue any announcement required by

Applicable Law or the rules of any national securities exchange to which the disclosing party is subject or by any Governmental Authority,

the applicable Party shall give the other Parties reasonable opportunity to comment on such announcement or release before it is made

or issued; provided, that opportunity to comment shall not have the effect of preventing the Party making the announcement or

release from complying with its disclosure obligations hereunder.

Section

12.10 Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns

of each of the Parties; provided, however, that no Party shall have the right to assign its rights, duties or obligations

hereunder without the prior written consent of the other Parties.

Section

12.11 Confidentiality. The Parties acknowledge that their Affiliates are parties to the Mutual Non-Disclosure Agreement, dated

as of January 21, 2025 (the “Confidentiality Agreement”), which is incorporated herein by reference, and agree to

be bound by and to fulfill and perform the obligations of their applicable Affiliates thereunder, mutatis mutandis as if a party

thereto. The Confidentiality Agreement shall continue in full force and effect, including with respect to the Parties hereto, regardless

of any termination of this Agreement, until the earlier of (a) August 1, 2027 and (b) the occurrence of the Closing.

Section

12.12 Entire Agreement. This Agreement and the Operating Agreement constitute the entire agreement among the Parties and their

respective Affiliates with respect to the subject matters hereof and thereof and supersede any and all other understandings and agreements,

Section

12.13 Amendment and Waiver. This Agreement (including any Annex, Exhibit or Schedule attached hereto) may be amended or modified

only with the written consent of the Company, the Investors, the Ground Lessee and the Guarantors. Each amendment, modification, or waiver

of this Agreement or any provision hereof made and approved in accordance with this Section 12.13 shall be binding on each Party.

No waiver of any term or provision hereof shall be effective unless signed in writing by the party waiving such term or provision. No

waiver by a party of any default, misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, shall be

deemed to extend to any prior or subsequent default, misrepresentation or breach of warranty or covenant hereunder or affect in any way

any rights arising by virtue of any prior or subsequent occurrence. No failure or delay by a party in exercising any right, power or

privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further

exercise thereof or the exercise of any other right, power or privilege.

Section

12.14 Severability. Each item and provision of this Agreement is intended to be severable. Except to the extent otherwise

expressly provided in this Agreement, if any term or provision of this Agreement is determined by a court of competent jurisdiction to

be unenforceable for any reason whatsoever, that term or provision shall be modified only to the extent necessary to be enforced, such

term or provision shall be enforced to the maximum extent permitted by Applicable Law, and the validity of the remainder of this Agreement

shall not be adversely affected thereby.

Section

12.15 No Third-Party Beneficiaries. Except with respect to Non-Party Affiliates under Section 12.2, nothing herein

expressed or implied is intended or shall be construed to confer upon or give any Person, other than the parties hereto and their successors

and permitted assigns, any rights or remedies under or by reason of this Agreement.

Section

12.16 Specific Performance. The parties hereto 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 money damages or legal

remedies would not be an adequate remedy for any such damages. Therefore, it is accordingly agreed that, in addition to any other remedy

at Applicable Law or in equity, the non-breaching parties shall be entitled to injunctive relief with respect to any such breach, including,

without limitation, specific performance of this Agreement or an order enjoining the breaching party from any threatened, or from the

continuation of any actual, breach of this Agreement by the breaching party to enforce specifically the terms and provisions of this

Agreement, to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the breaching

party, in a court of competent jurisdiction, and appropriate injunctive relief shall be granted in connection therewith without the necessity

of proving the inadequacy of money damages as a remedy and without the necessity of posting bond. Each of the Company, the Investors,

the Ground Lessee and the Guarantors agrees that it will not oppose the granting of an injunction, specific performance or other equitable

relief on the basis that (a) the Company, the Investors, the Ground Lessee or the Guarantors have an adequate remedy at Applicable Law

or (b) an award of specific performance is not an appropriate remedy for any reason at Applicable Law or in equity. Each of the Company,

the Investors, the Ground Lessee and the Guarantors hereby waives (i) any defenses in any action for specific performance, including

the defense that a remedy at law would be adequate, and (ii) any requirement to post a bond or other security as a prerequisite to obtaining

equitable relief.

Section

12.17 Counterparts. This Agreement may be executed in original or by other electronic communication (including PDF or DocuSign)
