Convertible Note Purchase Agreement

This Convertible Note Purchase Agreement (this “Agreement”), dated as of June 04, 2025, is entered into by and between MicroCloud Hologram Inc., a Cayman Islands exempted company (the “Company”), and the purchaser identified on the signature page hereto (including its successors and assigns, the “Purchaser”).

A. The Company and the Purchaser are executing and delivering this Agreement in reliance upon an exemption from securities registration afforded by the Securities Act of 1933, as amended (the “1933 Act”), and the rules and regulations promulgated thereunder by the United States Securities and Exchange Commission.

B. The Purchaser desires to purchase and the Company desires to Issue and sell, upon the terms and conditions set forth in this Agreement, certain series of Convertible Promissory Notes in the form attached hereto as Exhibit A, in the original principal amount of up to US$[ ] (the “Note”). Each Note shall be convertible into Class A ordinary shares of par value US$0.8 each of the Company (“Shares”), upon the terms and subject to the limitations and conditions set forth in the Note.

C. This Agreement, the Note, and all other certificates, documents, agreements, resolutions and instruments delivered to any party under or in connection with this Agreement, as the same may be amended from time to time, are collectively referred to herein as the “Transaction Documents”.

D. For purposes of this Agreement: “Conversion Shares” means all Shares issuable upon conversion of all or any portion of the Note; and “Securities” means the Note and the Conversion Shares.

NOW, THEREFORE, in consideration of the above recitals and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Purchaser hereby agree as follows:

1. Purchase and Sale of Securities.

1.1. Purchase of Securities. The Company shall issue and sell to Purchaser and each Purchaser shall purchase from the Company Convertible Promissory Notes in one or more tranches up to an aggregate principal amount of $[ ]. In consideration thereof, the Purchaser shall pay the purchase price in an amount equal to 92% of the original principal amount of each Note (the “Purchase Price”) to the Company upon each Closing.

1.2. Form of Payment. On the Closing Date (as defined below), the Purchaser shall pay the relevant Purchase Price to the Company via wire transfer of immediately available funds against delivery of the Note.

1.3. Closing Date. The issuance and sale of the Notes may occur in one or more closings (each, a “Closing”) on dates mutually agreed upon by the Company and Purchaser (each, a “Closing Date”), subject to the conditions herein. The initial Closing Date shall be on or about June 05, 2025.

2. Purchaser’s Representations and Warranties. The Purchaser represents and warrants to the Company that as of the date hereof and as of each Closing Date as follows (unless as of a specific date therein, in which case they shall be accurate as of such date):

(a) Organization; Authority. The Purchaser is either an individual or an entity duly incorporated or formed, validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership limited liability company or similar power and authority to enter into and to consummate the transactions contemplated by this Agreement and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of this Agreement and performance by the Purchaser of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate, partnership, limited liability company or similar action, as applicable, on the part of the Purchaser. Each Transaction Document to which it is a party has been duly executed by the Purchaser, and when delivered by the Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of the Purchaser, enforceable against it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

(b) Purchaser Status. At the time the Purchaser was offered the Securities, it was, and as of the date hereof it is, and on each Closing Date, it will be either: (i) an “accredited investor” as defined in Rule 501(a) under the 1933 Act or (ii) a “qualified institutional buyer” as defined in Rule 144A(a) under the 1933 Act. If it is not a U.S. Person (as defined in Regulation S), the Purchaser (i) acknowledges that the certificate(s) representing or evidencing the Conversion Shares shall contain a customary restrictive legend restricting the offer, sale or transfer of any Conversion Shares except in accordance with the provisions of Regulation S, pursuant to registration under the 1933 Act, or pursuant to an available exemption from registration, (ii) agrees that all offers and sales by the Purchaser of the Conversion Shares shall be made pursuant to an effective registration statement under the 1933 Act or pursuant to an exemption from, or a transaction not subject to the registration requirements of, the 1933 Act, (iii) represents that the offer to purchase the Securities was made to the Purchaser outside of the United States, and the Purchaser was, at the time of the offer and will be, at the time of the sale and is now, outside the United States, (iv) has not engaged in or directed any unsolicited offers to purchase Securities in the United States, (v) is not a Distributor (as such terms are defined in Rule 902(k) and 902(d), respectively, of Regulation S), (vi) has purchased the Securities for its own account and not for the account or benefit of any U.S. Person, (vii) is the sole beneficial owner of the Securities and has not pre-arranged any sale with the Purchaser in the United States, and (viii) is familiar with and understands the terms and conditions and requirements contained in Regulation S, specifically, without limitation, the Purchaser understands that the statutory basis for the exemption claimed for the sale of the Securities would not be present if the sale, although in technical compliance with Regulation S, is part of a plan or scheme to evade the registration provisions of the 1933 Act.

(c) Experience of Purchaser. The Purchaser, either alone or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Securities, and has so evaluated the merits and risks of such investment. The Purchaser is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

(d) Restricted Securities. The Purchaser acknowledges that absent an effective registration under the 1933 Act, the Securities may only be offered, sold or otherwise transferred (i) to the Company, or (ii) pursuant to an exemption from registration under the 1933 Act.

(e) Access to Information. The Purchaser acknowledges that it has had the opportunity to review the Transaction Documents (including all exhibits and schedules thereto) and all reports, schedules, forms, statements and other documents filed by the Company under the 1933 Act and Securities Exchange Act of 1934, as amended (the “1934 Act”), including pursuant to Section 13(a) or 15(d) thereof, including the exhibits thereto and documents incorporated by reference therein and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment.

(f) General Solicitation. The Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or, to our knowledge, any other general solicitation or general advertisement.

3. Company’s Representations and Warranties. The Company represents and warrants to the Purchaser that as of each Closing Date:

(a) Organization and Qualification. The Company is an exempted company with limited liability duly incorporated, validly existing and in good standing under the laws of the Cayman Islands, and each subsidiary of the Company is duly incorporated or organized, validly existing and in good standing (with respect to jurisdictions that recognize the concept of good standing) under the laws of its jurisdiction of organization. Each of the Company and its subsidiaries has the requisite power and authority to own, lease and operate its properties and to carry on its business as currently being conducted, and is duly qualified or licensed to do business in all material respects in each jurisdiction in which the property owned, leased or operated by it or the nature of the business conducted by it makes such qualification or licensing necessary.

(b) Authorization; Enforcement; Validity. The Company has the requisite corporate power and authority to execute and deliver the Transaction Documents and to perform its obligations thereunder. The execution, delivery and performance by the Company of the Transaction Documents, including the issuance of the Note and the Conversion Shares, have been duly authorized by all necessary corporate action on the part of the Company. Each Transaction Document to which the Company is a party has been or will be duly executed and delivered by the Company, and, assuming the due authorization, execution and delivery by the Purchaser and the other parties thereto, constitutes a legal, valid and binding obligation of the Company, enforceable against it in accordance with its terms, except as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally.

(c) Issuance of the Conversion Shares. The Conversion Shares are duly authorized and, when issued and paid for in accordance with the applicable Transaction Documents, will be duly and validly issued, fully paid and nonassessable, free and clear of all liens imposed by the Company.

(d) Capitalization. All issued and outstanding ordinary shares have been duly authorized and validly issued and are fully paid and non-assessable, were issued in compliance with applicable U.S. and other applicable securities laws and were not issued in violation of any preemptive right, resale right or right of first refusal.

(e) No Conflicts. The execution, delivery and performance by the Company of the Transaction Documents, including the issuance of the Note and the Conversion Shares, will not (i) result in a violation of the Memorandum and Articles, (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement to which the Company is a party, or (iii) result in a violation of any law applicable to the Company or by which any property or asset thereof is bound, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of the Company to perform its obligations under the Transaction Documents to which it is a party.

(f) Filings, Consents and Approvals. The Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other person in connection with the execution, delivery and performance by the Company of the Transaction Documents, other than such filings as are required to be made under applicable federal securities laws and the laws of the PRC.

(g) No Additional Representations. The Company makes no representations or warranties as to any matter whatsoever except as expressly set forth in the Transaction Documents or in any certificate delivered by the Company to the Purchaser in accordance with the terms thereof.
