The Business Plan was prepared in good faith; however, the Warrantor does not warrant that it will achieve any results projected in the Business Plan. It is understood that this representation is qualified by the fact that the Warrantor has not delivered to Purchaser, and has not been requested to deliver, a private placement or similar memorandum or any written disclosure of the types of information customarily furnished to purchasers of securities.

Company does not produce, design, test, manufacture, fabricate, or develop one or more “critical technologies” within the meaning of the Defense Production Act of 1950, as amended, including all implementing regulations thereof, and has no current intention of engaging in such activities in the future.

(s)Operation. DAS and Seller’s operation on the VDC Facility (as defined in the Second CFFA) and the Property (including creating any Liens on the VDC Facility or the Property) will not result in or cause any adverse effect or impact on Company’s Business or its operation of the Megawatt Space.

3.2Representations and Warranties of Purchaser. Purchaser hereby represents and warrants to Seller, as of the Effective Date, as of the Closing, and as of each Installment Date as follows:

(a)Organization and Existence. Purchaser has been duly organized and validly existing and is in good standing under the Laws of the Cayman Islands and has all requisite right, power and authority necessary to own, lease and operate all of its property and to carry on its business as it is now being carried on.

(b)Authority; Binding Obligation of Purchaser. Purchaser has all requisite power and authority to enter into this Agreement, to carry out its obligations hereunder and to consummate the 65 MW Transaction. This Agreement has been duly authorized, executed and delivered by Purchaser and, assuming due authorization, execution and delivery by Seller and any other party thereto, this Agreement shall constitute a legal, valid and binding obligation of Purchaser enforceable against it in accordance with its terms, subject to the Enforcement Qualifications.

(c)Consents and Approvals. No consent, approval or authorization of any non-governmental third party, and no consent, approval, authorization or declaration of, or filing or registration with, any Governmental Entity, is required to be made or obtained by Purchaser in connection with the execution and delivery of this Agreement by Purchaser or the consummation by Purchaser of the 65 MW Transaction.

(d)No Violation. The execution and delivery by Purchaser of this Agreement and the consummation of the 65 MW Transaction do not and will not (i) result in any violation of any Organizational Documents of Purchaser, (ii) result in any breach or default under any contract or permit to which Purchaser is a party or by which the assets or properties of Purchaser are subject (or result in the imposition of any Liens, charges, encumbrances, pledges, covenants, conditions, restrictions, and adverse claims or rights upon any of such assets or properties), or (iii) conflict with or violate any Law, rule, regulation, Order, writ, judgment, injunction, decree, determination, award, agreement, contract or obligation applicable to Purchaser or by which any of the assets or properties of Purchaser are bound.

(e)Investment Intent. Purchaser is aware of Company’s financial condition and has acquired sufficient information about Company to reach an informed and knowledgeable decision to acquire the Additional Units. Purchaser is purchasing the Additional Units for investment for its own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). Purchaser 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 party with respect to any of the Additional Units. Purchaser understands that the Additional Units have not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. Purchaser understands that the Additional Units are “restricted securities” under applicable U.S. federal and state securities Laws and that, pursuant to these Laws, Purchaser must hold the Additional Units indefinitely unless they are registered with the Securities and Exchange Commission and qualified by state authorities, or unless an exemption from such registration and qualification requirements is available. Purchaser acknowledges that Company has no obligation to register or qualify the Additional Units for resale. Purchaser further acknowledges that 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 the Additional Units, and requirements relating to Company which are outside of Purchaser’s control, and which Company is under no obligation and may not be able to satisfy.

(f)Due Diligence. Purchaser (i) has had an opportunity to ask questions of, and receive answers from, Seller regarding Company and the Property and the business, properties, prospects, and financial condition thereof, which questions were answered to its satisfaction, (ii) believes it has been furnished with such financial, legal, technical, personnel and operating data, and other information, as

Purchaser reasonably requested and (iii) understands that any business plans prepared on behalf of Company have been, and continue to be, subject to change and that any projections included in such business plans or otherwise are necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the projections will not materialize or will vary significantly from actual results, but were prepared in good faith. Purchaser acknowledges that it has made its own independent examination, investigation, analysis, and evaluation of Company and the Property, including Purchaser’s own estimate of the value of Company. Purchaser acknowledges that it has undertaken such due diligence (including a review of the assets, liabilities, books, records, and contracts of Company) as Purchaser deems adequate, including that described above.

(g)Independent Tax Advice. Purchaser has consulted any Tax consultants Purchaser deems advisable in connection with the purchase of the Additional Units, and Purchaser is not relying on Seller or Company for any Tax advice.

(h)Accredited Investor. Purchaser is an “accredited investor” within the meaning of Regulation D, Rule 501(a), or otherwise qualifies under the “safe harbor” provisions of Rule 506 of Regulation D for the private offering exemption available under Section 4(a)(2) of the Securities Act, as promulgated by the Securities and Exchange Commission.

4.5Without prejudice to and in addition to such other obligations of the Warrantors as provided under this Agreement, the Warrantors shall maintain all the other parts of the Property other than the Megawatt Space in proper condition so that the use of the Megawatt Space for the purpose of the Business will not be adversely affected.

Notwithstanding the previous sentence, Purchaser shall have no obligation to take or accept any action, condition, or restriction as a condition of CFIUS Clearance.

4.9Right of First Negotiation. During the period commencing on the date of Closing and ending on the date that is three (3) years after the date of Closing (the “ROFN Period”), if Seller determines to lease, license, or otherwise dispose of any additional Megawatt Space within the VDC Facility, including, but not limited to, through the sale of any additional equity interest of Company that confers the exclusive access to such Megawatt Space (each a “Covered Transaction”), Seller shall not, directly or indirectly through an Affiliate, enter into negotiations or consummate any transaction relating in any way to a Covered Transaction with any Person other than Purchaser except in compliance with the terms and conditions of this Section 4.9. Seller shall notify Purchaser in writing (the “Seller Notification”) of the availability of any such additional Megawatt Space within the VDC Facility (“Additional Megawatt Space”) and, within five (5) business days after the receipt of the Seller Notification, Purchaser shall notify Seller of its desire to engage in negotiations with Seller regarding a potential Covered Transaction regarding the Additional Megawatt Space (the “Purchaser Notification”). Seller shall engage in exclusive good faith negotiations with Purchaser to reach agreement on the terms and conditions for a Covered Transaction regarding the Additional Megawatt Space for a period of twenty (20) business days after receipt of the Purchaser Notification (the “Negotiation Period”), which shall subject to extension as agreed upon by Seller and Purchaser. If the parties are not able to reach an agreement during the Negotiation Period or the Purchaser does not send a Purchaser Notification, then Seller may enter into negotiations with any third party regarding a Covered Transaction for the Additional Megawatt Space specifically described in the Seller Notification; provided that such Covered Transaction with any third party shall be in compliance with the relevant terms in the Amended and Restated LLC Agreement. For clarity, for any other additional Megawatt Space not described in the Seller Notification or becoming available after the Negotiation Period, Seller shall not enter into negotiations or consummate any transaction relating in any way to a Covered Transaction with any third party regarding such additional Megawatt Space unless it complies with this Section 4.9 again.
