This Amendment No. 4 does not contain copies of the prospectus included in the Registration Statement, which remains unchanged from the Registration Statement filed on July 5, 2022.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Cayman Islands law does not limit the extent to which a company’s articles of association may provide indemnification of officers and directors, except to the extent that any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as providing indemnification against fraud, dishonesty or the consequences of committing a crime.

Our post-offering amended and restated memorandum and articles of association that will become effective immediately prior to the completion of this offering provide that each officer or director of our company (but not auditors) shall be indemnified out of our assets against all actions, proceedings, costs, charges, expenses, losses, damages or liabilities incurred or sustained by such director or officer, other than by reason of such person’s own dishonesty or fraud, in or about the conduct of our company’s business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his or her duties, powers, authorities or discretions, including without prejudice to the generality of the foregoing, any costs, expenses, losses or liabilities incurred by such director or officer in defending (whether successfully or otherwise) any civil proceedings concerning our company or its affairs in any court whether in the Cayman Islands or elsewhere.

Under the form of indemnification agreement filed as Exhibit 10.1 to this registration statement, we will agree to indemnify our directors and executive officers against certain liabilities and expenses incurred by such persons in connection with claims made by reason of their being such a director or executive officer.

The form of underwriting agreement to be filed as Exhibit 1.1 to this registration statement will also provide for indemnification of us and our officers and directors.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us under the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

II-1

During the past three years, we have issued and sold the securities. We believe that each of the following issuances was exempt from registration under the Securities Act in reliance on Regulation S under the Securities Act regarding sales by an issuer in offshore transactions. We believe that our issuances of options to our employees, directors, officers and consultants were exempt from registration under the Securities Act in reliance on Rule 701 under the Securities Act. No underwriters were involved in these issuances of securities.

(a)    Exhibits

See Exhibits Index beginning on page II-4 of this registration statement.

(b)    Financial Statement Schedules

Schedules have been omitted because the information required to be set forth therein is not applicable or is shown in the Consolidated Financial Statements or the Notes thereto.

II-2

The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement, certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 6, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

Ladies and Gentlemen:

Nano Labs Ltd, an exempted company incorporated with limited liability under the laws of the Cayman Islands (the “Company”), proposes to issue and sell to the several Underwriters named in Schedule I hereto (the “Underwriters”) an aggregate of [3,540,000] Class A ordinary shares, par value US$0.0001 per share, of the Company (the “Firm Shares”) in the form of [1,770,000] American Depositary Shares (as defined below).

The Company also proposes to issue and sell to the several Underwriters not more than an additional [531,000] Class A ordinary shares, par value US$0.0001 per share, of the Company (the “Additional Shares”) in the form of [265,500] American Depositary Shares, if and to the extent that AMTD Global Markets Limited, Maxim Group LLC and Tiger Brokers (NZ) Limited as representatives of the Underwriters (collectively, the “Representatives”), shall have determined to exercise, on behalf of the Underwriters, the right to purchase such Additional Shares granted to the Underwriters in Section 2 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the “Shares.” The Class A ordinary shares, par value US$0.0001 per share, of the Company to be issued, outstanding after giving effect to the sales contemplated hereby are hereinafter referred to as the “Ordinary Shares.”

The Underwriters will take delivery of the Shares in the form of American depositary shares (the “American Depositary Shares” or “ADSs”). The ADSs are to be issued pursuant to a Deposit Agreement dated as of [•], 2022 (the “Deposit Agreement”) among the Company, Citibank, N.A., as depositary (the “Depositary”), and the owners and holders from time to time of the ADSs issued under the Deposit Agreement. Each American Depositary Share will initially represent the right to receive two Ordinary Shares deposited pursuant to the Deposit Agreement.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement, including a prospectus, relating to the Shares and a registration statement relating to the ADSs. The registration statement relating to the Shares, as amended at the time it becomes effective, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A under the U.S. Securities Act of 1933, as amended (the “Securities Act”), is hereinafter referred to as the “Registration Statement;” the prospectus in the form first used to confirm sales of Shares (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Prospectus.” The registration statement relating to the ADSs, as amended at the time it becomes effective, is hereinafter referred to as the “ADS Registration Statement.” If the Company has filed abbreviated registration statements to register additional Ordinary Shares or ADSs pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statements”), then any reference herein to the terms “Registration Statement” and “ADS Registration Statement” shall be deemed to include the corresponding Rule 462 Registration Statement. The Company has filed, in accordance with Section 12 of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), a registration statement on Form 8-A to register the Shares and the ADSs (the “Form 8-A Registration Statement”).

(a) The Company agrees to indemnify and hold harmless each Underwriter, each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act who is involved in the Public Offering, each director, officer, employee and affiliate of any of the foregoing, and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities, joint or several, or any action in respect thereof (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, the ADS Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show as defined in Rule 433(h) under the Securities Act (a “road show”), or the Prospectus or any amendment or supplement thereto, or any Written Testing-the-Waters Communication, or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein in the light of the circumstances in which they were made, not misleading, and shall reimburse each Underwriter and each such director, officer, employee, affiliate or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee, affiliate or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; except insofar as such losses, claims, damages or liabilities are arising out of or based upon any such untrue statement or omission or alleged untrue statement or omission in reliance upon and in conformity with the Underwriter Information (as defined in Section 9(b) hereof).

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus or the Prospectus or any amendment or supplement thereto, it being understood and agreed that the only such information furnished by any Underwriter consists of the names and the addresses of the Representatives appearing in the [eleventh] paragraph under the caption “Underwriting” (the “Underwriter Information”).

32

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a) or 9(b) hereof, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing, provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 9 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 9. The indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the (i) fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act who are involved in the Public Offering, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and such affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding, and (y) does not include any statement as to, or any admission of, fault, culpability or a failure to act by or on behalf of any indemnified party.

33

(d) To the extent the indemnification provided for in Section 9(a) or 9(b) hereof, is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 9(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(d)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

(e) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 9(d) hereof. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(d) hereof shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

34

(f) The indemnity and contribution provisions contained in this Section 9 and Section 6(n) hereof and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of (A) any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter who is involved in the Public Offering, or (B) the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

10. Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE MKT, the Nasdaq Stock Market, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in commercial banking, securities settlement, payment or clearance services in the United States, Hong Kong, PRC, the Cayman Islands or Singapore, shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by United States Federal, New York State, Hong Kong, the PRC or the Cayman Islands authorities, (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets, currency exchange rates or controls or any calamity or crisis that, in the judgment of the Representatives, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

11. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than [one-tenth] of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 11 by an amount in excess of [one-ninth] of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than [one-tenth] of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter and the Company. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than [one-tenth] of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

35

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

12. Submission to Jurisdiction; Appointment of Agent for Service. The Company hereby irrevocably submits to the exclusive jurisdiction of the U.S. federal and state courts in the Borough of Manhattan in The City of New York (each, a “New York Court”) in any suit or proceeding arising out of or relating to this Agreement, the Deposit Agreement, the Time of Sale Prospectus, the Prospectus, the Registration Statement, the ADS Registration Statement, the offering of the ADSs or any transactions contemplated hereby. The Company and each of the Company’s Subsidiaries irrevocably and unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement, the Deposit Agreement, the Time of Sale Prospectus, the Prospectus, the Registration Statement, the ADS Registration Statement, the offering of the ADSs or any transactions contemplated hereby in the New York Courts, and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum. To the extent that the Company has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Company irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding. The Company irrevocably appoints Cogency Global Inc. as its authorized agent (the “Authorized Agent”) in the Borough of Manhattan in The City of New York upon which process may be served in any such suit or proceeding, and agree that service of process in any manner permitted by applicable law upon such agent shall be deemed in every respect effective service of process in any manner permitted by applicable law upon the Company, as the case may be, in any such suit or proceeding. The Company further agrees to take any and all action as may be necessary to maintain such designation and appointment of such agent in full force and effect for a period of seven years from the date of this Agreement. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY AND ALL RIGHTS TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

36

13. Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Company pursuant to this Agreement with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriter or controlling person may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Company agrees as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person hereunder, such Underwriter or controlling person agrees to pay to the Company, an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter or controlling person hereunder.

14. Entire Agreement. This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the sale and purchase of the Shares and the offering of the ADSs, represents the entire agreement between the Company and the Underwriters with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares and the offering of the ADSs.

15. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

16. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

17. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

(d) Waiver. The Company waives, to the fullest extent permitted by law, any claims it may have against the each of the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that none of the Representatives shall have any liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including shareholders, employees or creditors of the Company.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

FORM OF LOCK-UP LETTER

[•], 2022

Ladies and Gentlemen:

The undersigned understands that AMTD Global Markets Limited, Maxim Group LLC and Tiger Brokers (NZ) Limited, as representatives (each, a “Representative,” and collectively, the “Representatives”) of the several underwriters (the “Underwriters”) under the Underwriting Agreement, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Nano Labs Ltd, an exempted company incorporated with limited liability under the laws of the Cayman Islands (the “Company”), providing for the public offering (the “Public Offering”) by the several Underwriters, including the Representatives, of a certain number of Class A ordinary shares, par value US$0.0001 per share, of the Company (the “Ordinary Shares”) in the form of American Depositary Shares (“American Depositary Shares”).

49

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 180 days after the date of the final prospectus (the “Restricted Period”) relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Ordinary Shares or American Depositary Shares (collectively, the “Securities”) beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for the Securities or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of the Securities or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to the Securities or other securities of the Company acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of the Securities or other securities acquired in such open market transactions, (b) transfers of shares of the Securities or any security convertible into the Securities as a bona fide gift, (c) distributions of the Securities or any security convertible into the Securities to limited partners or stockholders of the undersigned; provided that in the case of any transfer or distribution pursuant to clause (b) or (c), (i) each donee or distributee shall sign and deliver to the Representatives a lock-up letter substantially in the form of this letter and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of the Securities, shall be required or shall be voluntarily made during the Restricted Period, or (d) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of the Securities, provided that such plan does not provide for the transfer of the Securities during the Restricted Period and to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of the Securities may be made under such plan during the Restricted Period. In addition, the undersigned agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any Securities or any security convertible into or exercisable or exchangeable for the Securities. The undersigned hereby also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Securities unless such transfer is in compliance with the foregoing restrictions.

In addition, nothing in this letter shall be deemed to prohibit (i) any transfer of any undersigned’s Securities to the Company for the primary purpose of satisfying any tax or other governmental withholding obligation, through cashless surrender or otherwise, with respect to any award of equity-based compensation to be granted pursuant to the Company’s pre-existing equity incentive plans or in connection with tax or other obligations as a result of testate succession or intestate distribution, (ii) any transfer of undersigned’s Securities pursuant to any contractual arrangement that provides for the repurchase of undersigned’s Securities by the Company in connection with the termination of the undersigned’s employment or other service relationship with the Company or any subsidiaries of the Company, or (iii) the exercise of any rights to acquire any undersigned’s Securities by means of cash or cashless exercises or the disposition of the undersigned’s Securities to the Company, or exchange or conversion of any stock options or any other securities convertible into or exchangeable or exercisable for undersigned’s Securities granted pursuant to the Company’s pre-existing equity incentive plans, provided that any undersigned’s Securities received upon such exercise, exchange or conversion shall be subject to the terms of this letter.

50

[If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed Securities the undersigned may purchase in the Public Offering.

If the undersigned is an officer or director of the Company, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of the Securities, one of the Representatives will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by issuing a press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this letter that are applicable to the transferor, to the extent and for the duration that such terms remain in effect at the time of the transfer.]²

The undersigned understands that the Company and the Underwriters are relying upon this letter in proceeding toward consummation of the Public Offering. The undersigned further understands that this letter is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Representatives on behalf of the Underwriters. This letter shall terminate and be of no further force or effect if the Underwriting Agreement is terminated pursuant to its terms.

This letter is governed by, and to be construed in accordance with, the internal laws of the State of New York, without regard to the conflict of laws principles thereof.
