1.01 Entry into a Material Definitive Agreement.

connection with the development of the Kati 2 project of Soluna Holdings, Inc. (the “Company”), on June 3, 2026 (the

“Effective Date”), Soluna HPC KK II HoldCo, LLC (the “Soluna Member”), a wholly owned subsidiary of Soluna

HPC, Inc., a wholly owned subsidiary of the Company, entered into a limited liability company agreement (the “Joint Venture

Agreement”) with DC Kati Venture LLC (the “Metrobloks Member”) to govern the terms of operation of Soluna MB KK II

JVCo, LLC (the “Joint Venture”). The Metrobloks Member is managed by Metrobloks LLC. The Joint Venture will invest in a

newly formed entity to develop and operate a multi-phase data center development in Willacy County, Texas, frequently referred to as

project “Kati 2” (such data center, “Project Kati 2”). The first phase of Project Kati 2 shall be a 100 MW

critical IT data center development (“Phase I”) and the second phase of Project Kati 2 will develop an additional 250 MW

critical IT data center development (“Phase II”).

The

Soluna Member and the Metrobloks Member are the sole members of the Joint Venture, with the Soluna Member holding 100% of the Class A

Interests and the Metrobloks Member holding 100% of the Class B Interests as of the Effective Date. The Joint Venture is a manager-managed

limited liability company, with the Soluna Member serving as the manager.

Pursuant

to the terms of the Joint Venture Agreement, as of the Effective Date, the Soluna Member contributed the Phase I Property (as defined

therein), a purchase agreement to acquire the Phase II Property (as defined therein), and funded certain operating expenses of approximately

$3.5 million. Subject to the closing of the purchase agreement, the Soluna Member has committed to fund a capital contribution of approximately

$19.0 million to complete the acquisition of the Phase II Property as well as an additional capital commitment of up to $2.0 million

to fund certain operating expenses as they become due. After the Soluna Member has received repayment of its capital contributions, recognized

a 14% IRR on its capital contributions and received $100,000 per Gross PPA MW of Project Kati 2, the Soluna Member and the Metrobloks

Member shall each receive 50% of additional distributions.

MEMBERSHIP;

CAPITAL CONTRIBUTIONS; CAPITAL ACCOUNTS; REVALUATIONS

3.01.

Membership Interests.

(a)

Subject to the terms of this Agreement, the Company is authorized to issue Membership Interests, which shall constitute limited liability

company interests under the Act. The Membership Interests initially shall consist of two (2) classes, “Class A Interests”

and “Class B Interests,” and shall have the rights, preferences, privileges, limitations, restrictions and/or obligations

as set forth herein. Subject to the terms of this Agreement, the Manager is authorized to create and issue new Membership Interests or

other Securities, which may have rights, preferences, privileges, limitations, restrictions and/or obligations that are junior to, pari

passu with or senior to any other class or series of Membership Interests or other Securities. To the fullest extent permitted by

the Act, but subject to the terms of this Agreement, the Manager may cause the Company to issue Membership Interests or other Securities

from time to time in one or more classes, or one or more series of such classes, which classes or series (or the holders thereof) shall

have, subject to the provisions of Applicable Law, such rights, preferences, privileges, limitations, restrictions and/or obligations

as shall be fixed by the Manager. In creating a class or series of Membership Interests in accordance with this Section 3.01(a),

the Manager may grant rights, preferences and privileges solely with respect to that class or series, and not others, and may also impose

limitations, restrictions and/or obligations with respect to class or series that are different from those with respect to any other

class or series.

(b)

The Company is hereby authorized (but is not obligated, unless so determined by the Manager) to issue certificates representing the ownership

of Membership Interests in accordance with the Act.

-3-

(c)

Subject to the terms of this Agreement, the Manager shall have the right at any time and from time to time to cause the Company to issue

Class B Interests to Eligible Persons pursuant to Separate Agreements. Separate Agreements with respect to each Class B Interest shall

set forth (i) the allocation and distribution provisions with respect to such Class B Interest, and (ii) the vesting, forfeiture, repurchase,

transfer and other provisions with respect to such Class B Interest, as determined by the Manager, in its sole and absolute discretion,

subject in all respects to the provisions of this Agreement. Each Class B Interest issued pursuant to a Separate Agreement is intended

to qualify as a Class B Interest for federal income tax purposes such that if the Company’s assets were sold at fair market value

immediately after the grant to a holder of a Class B Interest, and the proceeds were distributed in complete liquidation of the Company,

the holder of such Class B Interest would not be entitled to receive any share of such proceeds. The Manager may adjust the allocation

and distribution provisions for any Class B Interests as it deems appropriate in connection with any subsequent capital contribution,

issuance of Membership Interests, redemption or repurchase of Membership Interests or other similar transaction. Class B Interests shall

be treated as issued and outstanding as of the date of issuance and will, except as otherwise provided in the Separate Agreement with

respect to such Class B Interests, be treated as Class B Interests with an initial Capital Account of $0.

(i)

It is the intention of the parties to this Agreement that each Class B Interest qualifies as a “profits” interest, as defined

in Rev. Proc. 93-27, 1993-2 C.B. 343, as clarified by Rev. Proc. 2001-43, 2001-2 C.B. 191, and the Company and the Members shall comply

with the provisions of Rev. Proc. 93-27 and Rev. Proc. 2001-43 relating to qualification of each Class B Interest eligible for the favorable

tax treatment described in such Revenue Procedures. To that end, the Company and each Member agree that it is the intention of the Members

that allocations and distributions to each holder of a Class B Interest be limited to the extent necessary so that each Class B Interest

qualifies as a Class B Interest for federal income tax purposes, and this Agreement shall be interpreted consistently therewith. The

Members agree that, with respect to each Class B Interest, the Manager may, in its sole and absolute discretion, take such action as

it deems necessary to enable the Class B Interests to be treated as Class B Interests and the Company to comply with the requirements

of the “Safe Harbor” election within the meaning of the Proposed Revenue Procedure of Notice 2005-43, 2005-24 IRB 1, Proposed

Regulations Section 1.83-3(e)(l) or Proposed Regulations Section 1.704-l(b)(4)(xii) at such time as such proposed Procedure and Regulations

are effective and to take such actions as may be required by pronouncements or Regulations issued by the Internal Revenue Service or

Treasury Department after the Effective Date to enable each such Class B Interest to continue to be treated as a Class B Interest for

federal income tax purposes.

3.02.

Powers of Members; Voting Rights. Subject to the express provisions of this Agreement, the Members shall have no power to exercise

any voting rights except as required by any non-waivable provisions of the Act or other Applicable Law and shall have no independent

power to bind the Company. In exercising any voting rights of the Members expressly provided in this Agreement or required under any

non-waivable provisions of the Act or Applicable Law: (i) each Class A Interests holder shall have voting rights in proportion to such

holder’s Class A Interests held by such holder on the applicable voting date; and (ii) holders of Class B Interests shall have

no voting rights (whatsoever) and no separate class voting rights. No Member shall have any independent power to bind the Company.

3.03.

Members and Capital Contributions; Acquisition of the Phase II Property; Additional Members; Additional Capital Contributions.

(a)

On or prior to the Effective Date, Soluna shall contribute, or cause the contribution of, (i) the Phase I Property to the Phase I LandCo

and (ii) the Original Buyer’s right, title and interest as buyer under the Purchase Agreement to the Phase II LandCo, which contributions

shall be deemed Capital Contributions of Soluna. The Capital Contributions of the Members (including the Capital Contributions of Soluna

pursuant to the foregoing sentence), which Capital Contributions include amounts funded prior to the Effective Date as identified on

Exhibit A-1, and all of the outstanding Membership Interests in the Company held by the Members, each of which has executed this

Agreement as of the Effective Date, are as set forth opposite such Member’s name on Exhibit A hereto. Subject to, and conditioned

upon, the occurrence of a closing under the Purchase Agreement, Soluna or one of its Affiliates shall fund, or cause to be funded on

behalf of Phase II LandCo, approximately $19,082,375 as a Capital Contribution (the “Acquisition Capital Contribution”),

to the closing escrow under the Purchase Agreement by wire transfer of immediately available federal funds to fund the acquisition of

the Phase II Property in accordance with the Purchase Agreement and pay closing costs in connection therewith. The address of each Member

is as set forth on Exhibit A. The aggregate amount of the Capital Contributions attributable to each Member as of the Effective

Date is as set forth on Exhibit A and shall be maintained in the books and records of the Company. Exhibit A shall be revised

from time to time by the Manager following (x) any issuance, repurchase or Transfer of Membership Interests to reflect such issuance,

repurchase or Transfer, or (y) a change of address of a Member, except that Exhibit A will not be revised if any of the actions

described in clause (x) above was taken in breach of the terms of this Agreement. In addition to the Acquisition Capital Contribution,

Soluna hereby commits to contribute a total amount, not to exceed $2,000,000 in the aggregate, to fund Necessary Expenses and other operating

expenses as they become due, in each case, subject to approval by the Manager (the “Soluna Capital Commitment”).

(b)

No Person shall be admitted to the Company as an additional Member without the consent of the Manager.

(c)

No additional Capital Contribution shall be made except the Soluna Capital Commitment or as otherwise approved by the Manager; provided

that notwithstanding the foregoing, in the event Soluna fails to timely fund any portion of the Soluna Capital Commitment required to

pay Necessary Expenses, Metrobloks may, but is not obligated to, make a loan to the Company in the amounts required to fund such Necessary

Expenses, which loan (a “Default Loan”) shall (1) be payable, without penalty or premium, upon a DevCo Event, a sale

of the Company, or any other distribution made pursuant to Section 5.02 and, (2) bear interest at a rate not to exceed the lesser

of (x) fifteen percent (15%) per annum and (y) the maximum rate permitted by applicable law. Such payments shall be applied first to

the payment of accrued interest on such Default Loans and then to the repayment of the principal amounts thereof. Default Loans made

most recently in time shall have priority over older Default Loans. The proceeds of each Default Loan being delivered to the Company

in immediately available funds and shall be deemed to have been advanced on the date actually advanced.

3.04.

Return of Capital Contributions; Special Rules. Except as otherwise expressly provided herein, no Member shall be entitled to

the return of any part of its Capital Contribution or to be paid interest in respect of either its Capital Account balance or its Capital

Contribution, no Member shall have any personal liability for the return of the Capital Contribution of any other Member, and no Member

shall have any priority over any other Member with respect to the return of any Capital Contribution.

Article

ALLOCATION

OF PROFITS AND LOSSES

After

giving effect to the special allocations set forth in Section 3 of Exhibit C, Profits and Losses for any Accounting Period

shall be allocated to the Members in a manner that, after giving effect to such allocations the Capital Accounts of the Members are,

as nearly as possible, in the same proportionate amounts as (a) the amount each Member would receive if all assets of the Company were

sold at the end of such Accounting Period for cash equal to their Gross Asset Values, all liabilities of the Company were satisfied in

accordance with their terms (limited in the case of nonrecourse liabilities to the Gross Asset Value of the property securing such liabilities)

and all remaining or resulting cash was distributed to the Members pursuant to Section 9.02(b), minus (b) such Member’s

share of Company Minimum Gain and Member Nonrecourse Debt Minimum Gain, computed immediately prior to such hypothetical sale of assets.

Article

DISTRIBUTIONS

5.01.

Time of Distributions. Distributions of cash or property shall be made from the Company to the Members in such amounts and at

such time or times as determined by the Manager, in its sole and absolute discretion, but in no event later than thirty (30) days following

the receipt of any such cash or property by the Company (subject to appropriate reserves as determined in good faith by the Manager).

5.02.

Distributions. All distributions to the Members made pursuant to Section 5.01 shall be made in the priorities and amounts

set forth below:

(a)

first, 100% to the Members who have made Default Loans until such Members have received aggregate distributions under this Section

5.02(a) in amounts: (i) first, equal to all accrued but unpaid interest with respect to such Default Loans in the priority provided

in Section 3.03(c); and (ii) thereafter, equal to the unreturned original principal amount of such Default Loans (and with respect

to Default Loans made at different times, in the priority provided in Section 3.03(c));

(b)

second, 100% to the Members pro rata in accordance with the Members’ outstanding and unreturned Capital Contributions until

until the applicable Members have received a 14% IRR on their Capital Contributions;

(d)

fourth, 100% to Soluna until Soluna has received aggregate distributions under this clause (d) equal to $100,000 per Gross

PPA MW of the Project; and

5.03.

[***].

5.04.

Withholding. To the fullest extent permitted by law, each Member hereby agrees to indemnify the Company and the Manager for its

allocable share of any applicable tax of any type whatsoever (including withholding taxes, state unincorporated business taxes, taxes

imposed under the Partnership Audit Rules and/or any liability for penalties, additions to tax or interest and expenses incurred in respect

thereof) attributable to such Member’s share of the income of the Company or attributable to distributions to such Member or resulting

from such Member’s failure to provide any requested information. To the extent that the Company is required by Applicable Law to

withhold or to make tax or other payments on behalf of or with respect to any Member (including withholding taxes, state unincorporated

business taxes, taxes imposed under the Partnership Audit Rules and, in all cases, any interest, penalties, additions to tax, and expenses

incurred in respect thereof), the Company shall withhold such amounts from any distribution and make such payments as so required. For

purposes of this Agreement, any amount so withheld or so paid shall be treated as a distribution to the Member on whose behalf such amount

was withheld or such payment was made. Similarly, if an amount is withheld from a payment to the Company as a result of a characteristic

of a Member of the Company (including a failure to provide appropriate tax forms or a characteristic of a Member related or affiliated

to such Member, including a direct or indirect beneficial owner thereof) and the Company is not able to recover such withheld amount,

such withheld amount shall be treated as a distribution to such Member. In lieu of distribution treatment under this Section 5.04,

the Manager may treat such amounts as a demand loan from the Company to the relevant Member, with interest at ten percent (10%) per annum

accruing from the date of payment by the Company (or the date that the Company would otherwise have received the amount withheld, in

the case of an amount withheld from a payment to the Company) until discharged by such Member by repayment. The Manager may, in their

sole and absolute discretion, satisfy any obligation of a Member under this Section 5.04 out of future distributions to such Member.

A Member’s obligation to pay or indemnify for a tax (and related interest and penalties) shall survive the Member selling or otherwise

disposing of its interest in the Company and the termination, dissolution, liquidation, or winding up of the Company. Any indemnity or

payment pursuant to this Section 5.04 shall not be a Capital Contribution but shall to the extent necessary to properly maintain

Capital Accounts, increase a Member’s Capital Account.

MANAGEMENT

6.01.

Management.

(a)

Management and control of the Company shall be vested exclusively in the Manager, and the business and affairs of the Company shall be

managed under the direction of the Manager in accordance with and subject to this Agreement. The Manager shall always retain the authority

to make management decisions notwithstanding any delegation of duties by the Manager to officers, employees or agents. As of the Effective

Date, the Manager is Soluna.

(i)

Notwithstanding any provision herein contained to the contrary, without the prior written approval of Metrobloks, the Manager shall not

permit the Company or any Subsidiary to execute, enter into, amend, modify, waive any right under or terminate any agreement between

the Company or any Subsidiary, on the one hand, and Soluna or owner of a direct or indirect interest in Soluna, or any Affiliate thereof,

on the other hand; provided, however, that the foregoing approval requirement shall not apply to any agreement or transaction that: (i)

is entered into on arms’-length terms (i.e., on terms no less favorable to the Company or such Subsidiary than those that would

be obtained in a comparable transaction with an unrelated third party negotiating at arm’s length) or (ii) involves transactional

value of less than $500,000 per annum, measured on a per transaction basis or in the aggregate for a series of related transactions.

-7-

(b)

A Person shall cease to serve as a Manager upon such Person’s death, dissolution or bankruptcy or a ruling by a court of competent

jurisdiction that such Person is incompetent. A Manager may voluntarily withdraw from such position at any time upon written notice to

all of the Members. A Person may be removed as the Manager only by the Person who has the right to designate the Manager in accordance

with Section 6.01(a). Any vacancy in the Manager position shall be filled solely by the Person who has the right to designate

the Manager in accordance with Section 6.01(a).

(c)

To the fullest extent permitted by Applicable Law (including §18-1101 of the Act), notwithstanding any other provision of this Agreement

or otherwise of Applicable Law, neither the Manager nor any Member (collectively, the “Covered Persons”), shall have

any fiduciary duty (including any duty of care or duty of loyalty) to the Company, the Manager or any Member by reason of this Agreement

or in its, his or her capacity as a Covered Person, nor shall any Covered Persons have any fiduciary duty (including any duty of care

or duty of loyalty) to any third party lenders, except that the Manager and the Members shall be subject to the implied contractual covenant

of good faith and fair dealing. To the fullest extent permitted by Applicable Law (including §18-1101 of the Act) and except as

provided in Section 6.04, neither the Manager nor any Member shall be liable, including under any legal or equitable theory of

fiduciary duty (including any duty of care or duty of loyalty) or other theory of liability, to the Company, the Manager or any Member.

The provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities of the Manager or the Members

otherwise existing at law or in equity, are agreed by the parties hereto to replace such other duties and liabilities of the Manager

and the Members. The Manager and each Member shall be fully protected in relying in good faith upon the records of the Company and upon

such information, opinions, reports or statements presented to the Company by any Person as to matters which the Manager or such Member

reasonably believes are within such Person’s professional or expert competence.

6.02.

Action by Written Consent. Any action permitted or required by the Act or this Agreement to be taken by the Manager may be taken

without a meeting if a written consent, setting forth the action taken, is signed by the Manager. Any action permitted or required by

the Act or this Agreement to be taken by the Members may be taken without a meeting if a consent in writing, setting forth the action

taken, is signed by the Members holding the minimum number of Class A Interests necessary to authorize such action in accordance with

this Agreement.

6.03.

Officers. The Manager has the authority to appoint, in its sole and absolute discretion, persons serving as officers of the Company

and to delegate to such persons such powers, duties and responsibilities as the Manager shall deem to be in the best interests of the

Company. Officers of the Company need not be Members and shall have the powers, duties and responsibilities delegated to them by the

Manager; provided, however, that the Manager shall always retain the authority to make management decisions (subject to

the terms of this Article VI) notwithstanding any delegation of duties by the Manager to any officer of the Company. Officers

of the Company shall serve at the pleasure and direction of the Manager, and may be removed or replaced, with or without cause, from

time to time, by the Manager, in its sole and absolute discretion, subject to Applicable Law and to any restrictions contained in any

Separate Agreement between the Company and any such officer. Officers, in the performance of their duties as such, shall owe to the Company

and the Members duties of loyalty and due care of the type owed by the officers of a corporation to such corporation and its stockholders

under the laws of the State of Delaware.

-8-

6.04.

Liability of Parties. To the extent not inconsistent with Applicable Law, neither the Manager, any Member or the Tax Representative,

nor any of their respective officers, directors, employees, partners, members, shareholders or Affiliates, nor any officer of the Company,

shall be liable, responsible or accountable in damages or otherwise to the Company or to the Manager or any Member for any action taken

or for any failure to act on behalf of the Company in connection with the business or operations of the Company, if the person acted

in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company, and, with

respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

6.05.

Indemnification. To the extent not inconsistent with Applicable Law, the Company shall indemnify and hold harmless the Manager,

the Members and the Tax Representative and all of their respective Affiliates, officers, directors, managers, employees, partners, members,

shareholders and agents, and all of the Company’s officers and its designees on the board of managers (or similar governing body)

of any Subsidiary of the Company, from any loss, liability, damage or expense (including any judgment, award or settlement and reasonable

attorneys’ costs, expenses and fees, costs and expenses of investigation, and other costs or expenses incurred in connection with

the defense of any actual or threatened action, proceeding or claim) arising out of (a) any acts or omissions or alleged acts or omissions

in connection with their activities or the activities of any of their respective employees or agents on behalf of the Company or any

Subsidiary thereof, or in connection with the business or operations of the Company or any Subsidiary thereof, and (b) any liability

imposed upon any of them under any statute, rule or regulation (including any statute, rule or regulation relating to environmental matters)

applicable to the Company or any Subsidiary thereof, or their respective officers, directors or employees; provided that the acts or

omissions or the alleged acts or omissions upon which the action or threatened action, proceeding or claim is based were not performed

or omitted by the indemnified party fraudulently, with willful misconduct, in bad faith or in violation of this Agreement or any Separate

Agreement, as determined by the Manager, in its sole and absolute discretion. Reasonable expenses incurred by any such indemnified party

in connection with the matters referred to above may be paid or reimbursed by the Company in advance of the final disposition of the

proceeding, regardless of whether the Company, a Member, or an Affiliate of the Company or Member, has asserted claims against the indemnified

party, upon receipt by the Company of (i) a written affirmation by the indemnified party of his or its good faith belief that he, she

or it met the standard of conduct necessary for indemnification by the Company, and (ii) a written undertaking by or on behalf of the

indemnified party to promptly repay such amount if it shall ultimately be determined by a court of competent jurisdiction (not subject

to further appeal) that he, she or it has not met that standard of conduct. The foregoing indemnification rights will be in addition

to and not in lieu of any other contractual rights to indemnification granted to any Person by the Company or any Subsidiary thereof.

-9-

6.06.

Confidentiality. Except as otherwise provided in this Section 6.06, as an inducement for each of the Members to enter into

this Agreement and in order to protect and preserve the legitimate business interests of each of the Members and the goodwill to be developed

by and acquired by the Company in its business, each Member agrees as follows:

(a)

Confidentiality. Each Member other than an Exempt Entity (including any Person other than any Exempt Entity who has ceased to

own any Membership Interest (except due to a dissolution pursuant to Section 9.01(a))) shall not, and shall use commercially reasonable

efforts to cause its Affiliates not to, except as explicitly permitted under any other written agreement duly signed by both the Company

and such Member and as permitted below, (i) use for any purpose, (ii) disclose to any Person, or (iii) keep or make copies of documents,

tapes, discs or programs containing, any Confidential Information concerning the Company’s or its Subsidiaries’ (if any)

respective businesses; provided, however, that nothing herein shall prohibit such Member from using or disclosing any such

Confidential Information which: (x) at the time of its use or disclosure is through no fault of such Member in violation hereof part

of the public domain by publication or otherwise; (y) was not acquired, directly or indirectly, subject to any confidentiality obligation

to the Company or its Affiliates; provided, that with respect to each Member, the exception in this clause (y) shall not apply

to any Confidential Information that was in such Member’s possession prior to its entrance into this Agreement to the extent such

Confidential Information is used in the Company’s or its Subsidiaries’ respective businesses; or (z) is required or requested

to be disclosed by such Member pursuant to Applicable Law or court order or governmental authority, in which case, such Member shall

(A) give prompt written notice to the Company or the applicable Member, prior to any such disclosure to the extent permitted by Applicable

Law (B) in the case of Confidential Information of the Company or its Subsidiaries (if any), consult with the Manager on the advisability

of taking legally available steps to resist or narrow such request, and (C) in the case of Confidential Information of the Company or

its Subsidiaries (if any), assist the Manager in seeking a protective order or other appropriate remedy. In the event that such protective

order or other remedy is not obtained or that the Manager waives compliance with the provisions hereof, the disclosing Member shall disclose

only that portion of such Confidential Information that it, upon the advice of counsel, is legally required to disclose. For purposes

hereof, “Confidential Information” shall, with respect to the Company and its Subsidiaries (if any), mean and include

all intellectual property, trade secrets, reports, financial information, business plans, customers and/or suppliers lists and customer

and/or supplier information, and all other information concerning the Company’s or its Subsidiaries’ business and marketing

methods used in connection with their respective businesses, not previously disclosed to the public directly by the Company or its Subsidiaries

(if any), whether or not marked or delineated as confidential or the equivalent.

(b)

Equitable Relief for Violations. The parties agree that the provisions and restrictions contained in this Section 6.06

are necessary to protect the legitimate continuing interests of the Company, and that any violation or breach of these provisions will

result in irreparable injury to the Company for which monetary damages or any other remedy at law would be inadequate and that, in addition

to any relief at law which may be available to the Company for such violation or breach and regardless of any other provision contained

in this Agreement, the Company shall be entitled to seek temporary and permanent injunctive relief (without the necessity of having to

prove actual damages therefrom or post a bond therefore) and such other equitable relief as a court may grant.

(c)

Non-Applicability to Exempt Entities. Notwithstanding anything contained herein to the contrary and for the avoidance of doubt,

none of the Exempt Entities shall be subject to this Section 6.06.

-10-

6.07.

Freedom to Pursue Opportunities. Each of the parties hereto expressly acknowledges and agrees that notwithstanding any duty hereunder

or that may otherwise exist at law or in equity, to the fullest extent permitted by Applicable Law, but subject to any agreement between

the Company or any Affiliate thereof, on one hand, and any Member, on the other hand, (i) each of the Members has the right to, and shall

have no duty (contractual, fiduciary or otherwise) not to, by virtue of any equity ownership in the Company or service as the Manager,

directly or indirectly, engage in any business, business activity or line of business, including those that are the same or similar to

those of the Company or may be deemed to be competing with the Company or to otherwise be engaged in any business established or contemplated

market regions of the Company; and (ii) in the event that any Member acquires knowledge of a potential transaction or matter that may

be a business opportunity for the Company and/or one or more of its Affiliates, then such Member shall have no duty (contractual, fiduciary

or otherwise) to communicate or present such business opportunity to the Company or any of its Affiliates, and notwithstanding any provision

of this Agreement to the contrary, except in the case of Disabling Conduct, shall not be liable to the Company or any of its Affiliates

or Members for breach of any duty (contractual, fiduciary or otherwise) by reason of the fact that such Member, directly or indirectly,

pursues or acquires such opportunity for itself, directs such opportunity to another Person, or does not present such opportunity to

the Company or any of its Subsidiaries.

6.08.

Metrobloks Consultation Rights. In connection with any DevCo Event, the Manager shall consult with Metrobloks in good faith with

respect to (a) the selection of any investors to be admitted to an entity formed in connection with the DevCo Event and (b) any major

terms of any debt financing agreement to be entered into in connection with the DevCo Event; provided, however, that the foregoing consultation

rights shall not constitute a consent right, and the Manager shall retain sole and exclusive authority to make all final decisions with

respect to such matters.

VII

RESTRICTIONS

ON TRANSFERS

7.01.

Restrictions on Transfers. Except as otherwise permitted by this Agreement, no Member may, directly or indirectly, Transfer all

or any portion of its Membership Interest in the Company without the prior written consent of the Manager, which consent may be granted

or withheld in the absolute and unreviewable discretion of the Manager.

7.02.

Conditions to Transfer. Notwithstanding any other provision of Section 7.01, no Transfer shall be permitted, except in

the case of a Transfer by a direct or indirect owner of such Member of such direct or indirect interests in such Member to one or more

immediate family members of a direct or indirect owner of such Member or trusts established for the benefit of such family members, unless

the following additional conditions precedent are satisfied (or waived by the Manager):

(a)

The transferor and transferee shall execute and deliver to the Company such documents and instruments of conveyance as may be necessary

or appropriate in the opinion of counsel to the Company and the Manager to effect such Transfer and to confirm the agreement of the transferee

to be bound by the provisions of this Agreement (including this Article VII);

(b)

At the Company’s request, the transferor shall furnish to the Company an opinion of counsel satisfactory to the Company that the

Transfer will not (i) cause the Company to be treated other than as a partnership for U.S. tax purposes, including but not limited to

pursuant to the “publicly traded partnership” rules under Code section 7704 and the Regulations promulgated thereunder, or

(ii) result in a withholding obligation on the Company under Code section 1446(f); and

-11-

(c)

At the Manager’s request, the transferor shall provide an opinion of counsel satisfactory to the Company to the effect that such

Transfer will not violate any applicable securities laws regulating the Transfer of securities or any of the provisions of any agreement

to which the Company is a party.

7.03.

Rights of Unadmitted Transferee. A transferee of a Membership Interest who is not admitted as a Member pursuant to Section

7.04, (including a transferee who acquired all or part of such Membership Interest by operation of law, judicial proceeding or other

manner not expressly permitted hereunder) shall be entitled to allocations and distributions attributable to the Membership Interest

Transferred to the same extent as if the transferee were a Member, but shall have no right to participate in the management of the Company,

or to vote or give a consent on any matter calling for the approval or consent of the Members (and any requisite percentage or majority

shall be computed as if the Transferred Membership Interest did not exist), shall have no right to any information or accounting of the

affairs of the Company, shall not be entitled to inspect the books or records of the Company and shall not have any of the other rights

of a Member under the Act or this Agreement (collectively, the “Non-Transferable Rights”).

7.04.

Admission of Transferee as Member. Subject to the other provisions of this Article VII, a transferee of a Membership Interest

may be admitted to the Company as a Member only upon satisfaction of all of the following conditions:

(a)

The Manager shall consent to such admission, which consent may be granted or withheld in the absolute and unreviewable discretion of

the Manager;

(b)

The Membership Interest with respect to which the transferee is admitted was acquired by means of a Transfer permitted under Section

7.01;

(c)

The transferee becomes a party to this Agreement as a Member and executes such documents and instruments as the Manager reasonably may

request as necessary or appropriate to confirm such transferee as a Member in the Company and such transferee’s agreement to be

bound by the terms and conditions hereof; and

(d)

The transferee furnishes copies of all instruments effecting the Transfer, opinions of counsel and such other certificates, instruments

and documents as the Company may require.

7.05.

Effect of Disposition. Following any Transfer (whether or not permitted) of a Member’s entire Membership Interest, the Member

Transferred.

-12-

7.06.

Prohibited Transfers. Any purported Transfer that is not permitted under Section 7.01 shall be null and void and of no

effect whatsoever. In the case of a Transfer or attempted Transfer that is not such a permitted Transfer, the parties engaging or attempting

to engage in such Transfer shall be liable to indemnify and hold harmless the Company and the other Members from all cost, liability,

and damage that any of such indemnified persons may incur (including incremental tax liability and attorneys’ fees and expenses)

as a result of such Transfer or attempted Transfer and efforts to enforce the indemnity granted hereby.

7.07.

Intentionally Omitted.

7.08.

Conversion to Corporation or other Business Entity.

(a)

Notwithstanding anything contained herein to the contrary, the Manager may determine in good faith at any time, without requirement for

consent by any Member, that the Company or any of its Subsidiaries convert into a corporation or other business entity as the Manager

may determine, whether in connection with an offering of Securities or otherwise, or undergo a merger or consolidation having the effect

thereof (each, a “Conversion”). In the event that the Manager makes any such determination, the Manager and the Members

shall cooperate with each other in good faith so the Conversion is effected in a tax-efficient manner. Subject to the immediately preceding

sentence, in connection with any proposed Conversion approved by the Manager, the Manager may (i) cause this Agreement to be amended

to provide for the Conversion in accordance with Applicable Law, (ii) cause the distribution of shares, units or other equity interests

of any Subsidiary of the Company to the Members in accordance with Section 5.02, (iii) form a Subsidiary holding company and distribute

its shares to the Members, (iv) move the Company to another jurisdiction to facilitate any of the foregoing and/or (v) take such other

steps as it deems necessary or appropriate to effect the Conversion.

(b)

In connection with any proposed Conversion, at the option of the Manager, all or any portion of the Membership Interests (the “Pre-Conversion

Securities”) may be converted into or exchanged or redeemed for shares (or other equity securities and/or options at fair market

value, as determined by the Manager, in good faith) and other rights with substantially equivalent economic, governance, priority and

other rights and privileges as in effect immediately prior to such Conversion (disregarding the tax treatment of such conversion, exchange

or redemption) (the “Post-Conversion Securities”). In connection with any such conversion, exchange or redemption,

the number of Post-Conversion Securities to be issued to the Members in respect of the Pre-Conversion Securities shall be determined

on a consistent basis by the Manager based upon (i) the fair market value of the Company on the date of the Conversion as determined

in good faith by the Manager and (ii) the resulting relative values of the Pre-Conversion assuming the Company is dissolved and the net

proceeds are distributed to the owners of Pre-Conversion Securities in accordance with Section 5.02. If any such conversion, exchange

or redemption is effected, each Member agrees to execute and deliver all agreements, instruments and documents as may be reasonably requested

or required in order to consummate such conversion, exchange or redemption. For the avoidance of doubt, it is understood that all Members

owning the same Pre-Conversion Securities shall receive the same type and amount of Post-Conversion Securities on a pro rata basis

based on the relative amounts of such Pre-Conversion Securities owned by such Members immediately prior to the Conversion.

-13-

(c)

If the Manager determines to effect a Conversion, each Member shall cooperate in good faith with the Manager, including taking all actions

reasonably requested or required by the Manager, in connection with consummating the Conversion. Without limiting the generality of the

foregoing, in connection with the consummation of the Conversion, the corporation or other business entity into which the Company is

converted and each Member shall enter into a stockholders agreement having substantially identical terms and conditions as set forth

in this Section 7.08, Sections 6.04 and 6.05, this Article VII and Article XI.

7.09.

Repurchase Right.

(a)

If (x) a Cause Event described in clause (i) or (ii) of the definition thereof has occurred, (y) a Cause Event described in clause (iii)

or (iv) of the definition thereof is determined, through arbitration pursuant to Section 11.03(c), to have occurred, or (z) a

Cause Event described in clause (iii) or (iv) of the definition thereof is deemed to have occurred due to Metrobloks’s failure

to timely provide an Arbitration Notice with respect to such Cause Event, then, the Company shall have the right (but not the obligation)

(the “Repurchase Right”), exercisable at any time during the 365-day period following the date of such Cause Event,

or in the case of a Cause Event described in clause (iii) of the definition thereof, date of such notice of Cause Event delivered to

Metrobloks, as applicable (the “Repurchase Exercise Period”), to cause the Company to purchase from Metrobloks, in

whole but not in part, the Membership Interests that were issued on after the Effective Date and are then held by Metrobloks on the terms

and conditions set forth in this Section 7.09 (the “Repurchase Interests”) at the Repurchase Price. For purposes

hereof, the term “Repurchase Price” means, with respect to the Repurchase Interests held by Metrobloks, the Fair Value

of the Interest determined in accordance with Section 7.10. Notwithstanding anything contained in this Agreement to the contrary,

the Manager shall, in good faith, endeavor to structure each purchase and sale of the Repurchase Interests pursuant to this Section

7.09(a) in a tax-efficient manner for the benefit of the Company and Metrobloks. Each notice of Cause Event delivered to Metrobloks

pursuant to a Cause Event described in clause (iii) or (iv) of the definition thereof shall include the following statement set forth

in all capital letters: “YOU MAY ONLY DISPUTE THE EXISTENCE OF A CAUSE EVENT BY DELIVERY OF AN “ARBITRATION NOTICE”

TO SOLUNA WITHIN TEN (10) BUSINESS DAYS FOLLOWING THE DATE HEREOF. IF YOU FAIL TO DELIVER AN “ARBITRATION NOTICE” WITHIN

SUCH TEN (10) BUSINESS DAY PERIOD, A CAUSE EVENT SHALL CONCLUSIVELY BE DEEMED TO EXIST.” Metrobloks may only dispute the existence

of a Cause Event by delivery of notice (an “Arbitration Notice”) to Soluna within ten (10) Business Days after such

Member’s receipt of a notice of Cause Event. If Metrobloks fails to provide an Arbitration Notice within such ten (10) Business

Day period, then notwithstanding anything to the contrary in this Agreement, Metrobloks shall have no right to dispute the existence

of a Cause Event, and such Cause Event shall conclusively be deemed to have occurred.

(b)

The Company may exercise its Repurchase Right under this Section 7.09 upon determination of the Manager, in its sole and absolute

discretion. The Company may assign all or any portion of its rights to repurchase Membership Interests pursuant to this Section 7.09

to one or more Persons designated by it, including Soluna.

-14-

(c)

Upon the Manager’s determination to cause the Company to repurchase the Repurchase Interests pursuant to this Section 7.09,

the Manager shall give Metrobloks notice (the “Repurchase Notice”), specifying such determination, the Repurchase

Price of the Repurchase Interests and the date of such purchase, which purchase shall be held through an escrow style closing with an

escrow agent approved by the Manager and Metrobloks on a business day selected by Manager that is (x) sixty (60) days after the determination

of Fair Value of the Interest (as such term in is hereinafter defined) or (y) an earlier date agreed upon by Manager and Metrobloks.

On the date specified in the Repurchase Notice, Manager shall cause the Company to purchase, and Metrobloks shall sell, all of the Repurchase

Interests in exchange for the Repurchase Price (the “Repurchase Closing”); provided, however, that such

repurchase and sale of the Repurchase Interests shall be self-executing and shall be effective automatically, without further action,

notice or deed, upon payment of the Repurchase Price in accordance with this Section 7.09. [***].

(d)

The Repurchase Interests sold to the Company at the Repurchase Closing shall be free and clear of any and all Encumbrances (other than

Encumbrances under any financings encumbering the Property or the Company’s interest in any Subsidiary) and Metrobloks shall take,

at its sole cost and expense, all steps necessary to do so. Upon the Repurchase Closing, all Repurchase Interests referenced in the Repurchase

Notice shall, automatically and without further action or deed, be Transferred to the Company or its designee. From and after the Repurchase

Closing, (i) all rights of Metrobloks in respect of the Repurchase Interests shall cease, (ii) Exhibit A hereto shall be revised

to reflect the repurchase of such Repurchase Interests and (iii) Metrobloks shall cease to be a Member (or other equity holder, as applicable)

of the Company.

7.10.

Fair Value Determination.

(a)

The “Fair Value of the Interest” of Metrobloks shall be the amount Metrobloks would receive if the Property were sold

for the Fair Value at the time of the underlying event that caused the termination of the Design Services Management Agreement for Cause

and the proceeds of such sale were distributed to the Members in accordance with Section 5.02 hereof; provided, however, that

the such calculation shall take into account a reduction of the Fair Value by three percent (3%) for Imputed Closing Costs.

(b)

The “Fair Value” of the Property may be established by mutual agreement of Manager and Metrobloks, or, if Manager

and Metrobloks do not reach agreement as to the Fair Value within ten (10) days after the delivery of the Repurchase Notice, then the

“Fair Value” of the Property shall be determined by the appraisal process below.

(c)

If Manager and Metrobloks do not mutually agree as to the Fair Value within the time period specified therefor in clause (b) above, then

any such Member may serve written notice upon the other Member stating that the Fair Value shall be determined pursuant to this clause

(c).

-15-

(i)

Within ten (10) days after receipt of any such notice by a Member, Metrobloks shall nominate and appoint one Qualified Appraiser, and

Manager shall nominate and appoint another Qualified Appraiser. Upon the appointment of the two Qualified Appraisers as hereinabove provided,

the two Qualified Appraisers so appointed shall within fifteen (15) days after the appointment of the second Qualified Appraiser and

before exchanging views as to the question at issue, appoint in writing a third Qualified Appraiser and give written notice of such appointment

to the Members. In the event either Metrobloks, on the one hand, or Manager, on the other hand, fails to appoint a Qualified Appraiser

within the ten (10) day period set forth above, or the two Qualified Appraisers selected by such Members shall fails to appoint or agree

upon such third Qualified Appraiser within the fifteen (15) day period specified above, a Qualified Appraiser for such Member or the

third Qualified Appraiser, as the case may be, may be selected by the Members if they so agree upon such other or third Qualified Appraiser,

as applicable, within a further period of ten (10) days; otherwise, the Members may apply to the appropriate court of the state where

the Property is located for the appointment of any Qualified Appraiser not appointed or agreed upon within the time periods herein provided.

For purposes of this Agreement, a “Qualified Appraiser” shall mean an independent third party (i.e., not an Affiliate

of any Member) qualified M.A.I. appraiser with at least ten (10) years of experience with appraising real estate projects similar to

the Property and has not performed any work for the selecting Member within ten (10) years of the date of selection.

(ii)

The Qualified Appraisers selected pursuant hereto shall be sworn faithfully and fairly to determine the question at issue. The determination

to be made by the Qualified Appraisers shall be the current fair market value of the Property as of the date the Manager delivered the

Repurchase Notice pursuant to Section 7.09. The three Qualified Appraisers shall afford the applicable Members a hearing and right

to submit evidence, with all possible speed, make their determination in writing and give notice of the same to the Members. The “Fair

Value” shall be the value agreed to by at least two of the three Qualified Appraisers, or, if no two of the three Qualified

Appraisers shall render a concurring determination, then the Fair Value shall be the average of the values reached by the two Qualified

Appraisers with the closest fair market value determinations, and such Fair Value shall be conclusive and binding upon the Members. The

cost of each Qualified Appraiser shall be borne by the Member that appoints such Qualified Appraiser other than the third Qualified Appraiser

appointed by the first two Qualified Appraisers, by the Members jointly or by court appointment.

(d)

Upon determination of the Fair Value of the Property, the Manager shall cause the Company’s accountants to calculate the Fair Value

of the Interest of Metrobloks and shall notify the Members of such amount.

VIII

WITHDRAWAL

8.01.

Restrictions on Withdrawal. Except as otherwise expressly permitted in this Article VIII, without the consent of the Manager,

which consent may be granted or withheld in the absolute and unreviewable discretion of the Manager, a Member does not have the right

to withdraw from the Company as a Member or to terminate its Membership Interest.

-16-

8.02.

Withdrawal Payment; Reserves. Upon a permitted withdrawal, the withdrawing Member shall be entitled to receive its Capital Account

balance in the Company as of the withdrawal date (as determined after giving effect to the revaluation of Company assets pursuant to

Section 2 of Exhibit C), payable in cash or in kind, or a combination thereof, as the Manager may select, and subject to

the limitations and other provisions of this Article VIII. The payment to a withdrawing Member shall be made within ninety (90)

days after the date of withdrawal or, at the option of the Manager, in twenty (20) equal quarterly installments of principal, the first

of which shall be paid within ninety (90) days from the date of withdrawal, together with interest on the unpaid principal balance at

a rate equal to the mid-term applicable federal rate under Code section 1274 (for quarterly compounding periods) as of the date of withdrawal.

If installment payment is elected, interest shall accrue from the date of withdrawal and shall be paid together with each quarterly installment

of principal, and the Company at any time may prepay, in whole or in part, the amount owing, which prepayment shall be applied first

to accrued but unpaid interest and then to principal installments in their inverse order of maturity. The amount payable to a withdrawing

Member under this Section 8.02 may, as the Manager shall determine, be subject to reserves for subsequent adjustments in the computation

of the withdrawal amount and reserves for contingencies, including contingent liabilities relating to pending or anticipated litigation

10.02 shall be prepared at the expense of the Company (for the avoidance of doubt, not including any Member’s tax return).

In addition, within one hundred twenty (120) days after the end of each Fiscal Year, the Company shall cause to be prepared and delivered

to each Member annual audited financial statements of the Company for such Fiscal Year, prepared in accordance with generally accepted

accounting principles, consistently applied.

10.03.

Tax Elections; Determinations Not Provided for in Agreement. The Manager shall be empowered to make or revoke any elections now

or hereafter required or permitted to be made by the Code or any state or local tax law, and to decide in a fair and equitable manner

any accounting procedures and other matters arising with respect to the Company or under this Agreement that are not expressly provided

for in this Agreement. Notwithstanding the foregoing, absent the consent of the Manager to the contrary, the Company and all Members

shall take any steps that may be necessary to elect partnership status for purposes of the Code and any applicable state or local tax

law and shall not take any action or file any election inconsistent with such partnership status.

10.04.

Partnership Representative/Tax Audits.

(a)

Soluna is hereby designated as the Partnership Representative of the Company for purposes of the Code. With respect to any period in

which any non-individual is the Partnership Representative, the Partnership Representative shall cause the Company to appoint an individual

eligible to be a “designated individual” under the Code (the “Designated Individual”) through whom the

Partnership Representative will act. Promptly following the written request of the Partnership Representative and/or Designated Individual,

the Company shall, to the fullest extent permitted by Applicable Law, reimburse and indemnify the Partnership Representative and/or Designated

Individual, as the case may be, for all reasonable, documented out-of-pocket expenses, including reasonable legal and accounting fees,

claims, liabilities, losses and damages incurred by such person(s) (in its capacity as such) in connection with any administrative or

judicial proceedings with respect to the tax liability of the Company or the determination of the Company’s tax items or tax items

of Members in connection with the operations of the Company.

(b)

The Partnership Representative and the Designated Individual, if any, (collectively, the “Tax Representative”) shall

use their commercially reasonable efforts to apply the rules and elections under the Partnership Audit Rules in a manner that minimizes

the likelihood that any Member would bear any material tax, interest or penalties as a result of any audit or proceeding that is attributable

to another Member (other than a predecessor in interest). The Manager and Tax Representative are hereby authorized to take any action

required to cause the financial burden of any “imputed underpayment” (as determined under Code section 6225) and associated

interest, adjustments to tax and penalties arising from a partnership-level adjustment that are imposed on the Company (an “Imputed

Underpayment”) to be borne by the Members to whom such Imputed Underpayment relates as determined by the Tax Representative

after consulting with the Company’s accountants or other advisers, taking into account any differences in the amount of taxes attributable

to each Member because of such Member’s status, nationality or other characteristics.

-19-

(c)

By executing this Agreement, a counterpart hereof or a Joinder Agreement, each Member (i) expressly authorizes the Tax Representative

and the Company to take any and all action that is reasonably necessary under applicable federal income tax law (as such law may be revised

from time to time) to cause the Company to make the election set forth in Code section 6226(a) if the Tax Representative decides to make

such election, and (ii) expressly agrees to take any action, and furnish the Tax Representative with any information necessary, to give

effect to such election. Each Member hereby severally indemnifies and holds the Company, the Manager and the Tax Representative harmless

for such Member’s respective portion of the financial burden of any Imputed Underpayment in accordance with the terms of Section

5.04. Except with the express written consent of the Manager, each Member shall be jointly and severally liable with their predecessors

in interest, if any, for amounts owed hereunder in respect of any predecessor in interest to such Member. No Member shall file a notice

with the Internal Revenue Service under Code section 6222(c)(1)(B) in connection with such Member’s intention to treat an item

on such Member’s U.S. federal income tax return in a manner that is inconsistent with the treatment of such item on the Company’s

U.S. federal income tax return.

(d)

The provisions of this Section 10.04 shall survive the termination of the Company or the termination of any Membership Interest

and shall remain binding on the Members for as long a period of time as is necessary to resolve with the Internal Revenue Service any

and all matters regarding the federal income taxation of the Company or the Members (relating to the operations of the Company).
