issuance to the shareholders of the Company to a date immediately following the close of business on the record date for the determination of shareholders entitled to receive such Ordinary Shares or Company Equity Securities and (y) in all
other cases, on the date of such issuance; provided, however, that the determination as to whether an adjustment is required to be made pursuant to this Section 4.7(b) shall be made upon the issuance of such Ordinary Shares or Company

(1%) per annum, on the outstanding principal of this Note, due and payable in cash by the Company in arrears on each anniversary of the Original Note Issuance Date, from the Original Note Issuance Date until the earlier of (i) the Initial
Maturity Date, (ii) the date this Note is otherwise redeemed in full under Section 3.2, or (iii) such date on which this Note is converted in full under Section 4.1. Interest shall be calculated on the basis of a 365-day year for
the actual number of days elapsed. 

  

	 	(b)	Notwithstanding the foregoing, in the event that the Initial Maturity Date of this Note is extended pursuant to Section 2.1, this Note shall bear no interest for
any period between the Initial Maturity Date and the Extended Maturity Date. 

 SECTION 3 

REDEMPTION 
  

	3.1	Redemption on Maturity Date. The Company shall redeem the outstanding Principal Amount of this Note that has not been converted or redeemed as provided herein on
the Initial Maturity Date or the Extended Maturity Date, as the case may be, by payment of the Redemption Price to the Holder in cash; provided that in the event the Initial Maturity Date or the Extended Maturity Date, as the case may be,
falls within or after the Post-IPO Conversion Period, the Company shall redeem the outstanding Principal Amount of this Note that has not been converted or redeemed as provided herein at the expiration of the Post-IPO Conversion Period by payment of
the Post-IPO Redemption Price to the Holder in cash plus any accrued and unpaid Interest. 

  
 7 

  

	3.2	Post-IPO Redemption at Option of the Holder. At any time during the Post-IPO Conversion Period, the Holder of this Note shall have the right, but not the
obligation, to require the Company, by notice in writing (such notice to be in the form of Exhibit A attached hereto (a “Post-IPO Redemption Notice”)) to the Company, to redeem for cash all of the total outstanding Principal
Amount of this Note not previously redeemed by the Company or converted as provided herein at a price equal to the Post-IPO Redemption Price plus any accrued and unpaid Interest in priority to any payment on or with respect to the Company Equity
Securities. The Company shall pay the Holder the Post-IPO Redemption Price plus any accrued and unpaid Interest no later than twenty (20) Business Days after delivery of such Redemption Notice by the Holder of this Note.

  

	3.3	Default Redemption at Option of the Holder. Upon the occurrence of an Event of Default, the Holder of this Note shall have the right, but not the obligation, to
require the Company, by notice in writing (such notice to be in the form of Exhibit B attached hereto (a “Default Redemption Notice”)) to the Company, to redeem for cash all of the total outstanding Principal Amount of the
Notes not previously redeemed by the Company or converted as provided herein at a price equal to the then applicable Redemption Price in priority to any payment on or with respect to the Company Equity Securities. The Company shall pay the Holders
the applicable Redemption Price no later than twenty (20) Business Days after delivery of such Default Redemption Notice. 

  

	3.4	No Redemption at Option of the Company. Other than as set forth in this Section 3, the Company may not redeem, repurchase or repay any portion of this Note
at any time prior to the Initial Maturity Date or the Extended Maturity Date, as the case may be. 

SECTION 4 
 CONVERSION 
  

	4.1	Mandatory Conversion. Immediately prior to and subject to the completion of a Company Sale, all of the then outstanding Principal Amount of this Note and the
accrued and unpaid Interest thereon shall be automatically converted into such number of duly authorized, fully paid and non-assessable Ordinary Shares as is equal to the quotient of (i) such outstanding Principal Amount of this Note plus the
accrued and unpaid Interest thereon, divided by (ii) the applicable Conversion Price (and such Ordinary Shares shall be credited to the Holder’s securities account as notified to the Company). For the avoidance of doubt, the Ordinary
Shares, other Company Equity Securities and any other securities of the Company that the Holder is entitled to receive upon conversion of this Note pursuant to the preceding sentence shall entitle the Holder to receive the same type and amount of
consideration in exchange for or with respect to any other Ordinary Shares, other Company Equity Securities or any other securities of the Company in the Company Sale. 

  
 8 

  

	4.2	Optional Conversion. 

  

	 	(a)	At any time during the Post-IPO Conversion Period, the Holder of this Note shall have the right, but not obligation, to convert this Note in whole, into such number of
duly authorized, fully paid and non-assessable Ordinary Shares as is equal to the quotient of (i) the outstanding Principal Amount of this Note plus accrued and unpaid Interest thereon, divided by (ii) the Conversion Price; provided
that the Holder of this Note may convert this Note in part for purposes of selling or transferring Ordinary Shares issued upon conversion of such partial Principal Amount of this Note, including, without limitation, in connection with an IPO or in
the event the number of Registrable Securities (as defined in the Investors’ Rights Agreement) held by such Holder to be registered or sold is limited in accordance with the Investors’ Rights Agreement. 

 

	 	(b)	The conversion rights set forth in Section 4.2(a) above shall be exercised by the surrender by the Holder on a Business Day of this Note at any time during usual
business hours at the registered office of the Company at the offices of Offshore Incorporations (Cayman) Limited, Scotia Centre, 4th Floor, P.O. Box 2804, George Town, Grand Cayman, Cayman Islands (or such other office or agency of the Company as
the Company and the Majority Note Holders may agree) with a copy to the address of the Company as specified in the Convertible Note Purchase Agreement, accompanied by written notice (such notice to be in the form of Exhibit C attached hereto
(a “Conversion Notice”)) specifying (i) that the Holder elects to convert the entire Note or a portion thereof and (ii) the name or names (with address) in which a certificate or certificates for Ordinary Shares are to be
issued. In case of conversion at the completion of an IPO, a Conversion Notice may be delivered at such time prior to the completion of an IPO as may be reasonably required by the Company’s underwriter(s) for the IPO, which shall become
effective as of and subject to the completion of the IPO. This Note shall be delivered to the Company (together with the Conversion Notice) for cancellation and shall be canceled by it. As soon as practicable after the delivery of the Conversion
Notice, but in no event later than two (2) days thereafter, the Company shall (x) take all actions and execute all documents necessary to effect the issuance and registration of such Ordinary Shares (including giving all necessary
instruction to the relevant share registry to effect such issuance and registration but excluding the registration of the Ordinary Shares issued upon conversion of the Notes under the U.S. securities laws), and (y) deliver to the Holder a
certificate or certificates representing the number of duly authorized, fully paid and non-assessable Ordinary Shares calculated in accordance with Section 4.2(a) above. At the time of surrender of this Note, the Person in whose name any
certificate(s) for Ordinary Shares shall be issuable upon such conversion shall be deemed to be the holder of record of such Ordinary Shares on such date, notwithstanding that the share register of the Company shall then be closed or that the
certificates representing such Ordinary Shares shall not then be actually delivered to such Person. 

  
 9 

  

	4.3	Fractional Shares. No fractional Ordinary Shares shall be issued upon conversion of this Note. All Ordinary Shares (including fractions thereof) issuable upon
conversion of more than one Note held by a Holder thereof shall be aggregated for purposes of determining whether the conversion would result in the issuance of any fractional share. If, after the aforementioned aggregation, the conversion would
result in the issuance of any fractional share, the Company shall round up any such fractional share to one whole share. 

  

	4.4	Joinder Agreement. If the Holder of this Note is not yet a party to the Investors’ Rights Agreement, so long as the Investors’ Rights Agreement, is
still in force, as a pre-condition to the issuance by the Company of the Ordinary Shares issuable upon conversion of this Note, the Holder of this Note is required to execute a Joinder Agreement (as defined in the Investors’ Rights Agreement)
to join the Investors’ Rights Agreement as if it were an “Investor” thereunder. 

  

	4.5	Termination of Rights. All rights under this Note shall terminate when (a) the entire Principal Amount of this Note and any other amounts payable in
relation to this Note have been paid and received pursuant to Section 3 above or (b) this Note is converted in full pursuant to the terms of this Note. 

 

	4.6	Availability of Shares; Taxes. The Company covenants that it will at all times reserve and maintain authority to issue, solely for the purpose of issue or
delivery upon any conversion herein provided, the maximum number of Ordinary Shares reasonably expected to be issuable upon conversion of this Note. The Company covenants that all Ordinary Shares, when issued or delivered pursuant to
Section 4.1 and in compliance with the provisions of the Restated Articles, be duly and validly authorized and issued, fully paid and free and clear of all Encumbrances. The Company shall pay all taxes, liens and other charges whatsoever that
may be imposed in respect of the conversion of this Note or the issuance and delivery of the Ordinary Shares issuable upon the conversion of this Note. 

  

	4.7	Anti-dilution Adjustments. The Conversion Price, and the number and type of securities to be received by the Holder upon conversion of this Note pursuant to
Section 4.2(a), shall be subject to adjustment as follows: 

  

	 	(a)	Subdivision, Combination or Reclassification of Ordinary Shares. In the event that the Company shall at any time or from time to time, after the completion of an
IPO but prior to conversion of this Note pursuant to Section 4.2(a), (i) pay a dividend or make a distribution on the outstanding Ordinary Shares payable in Company Equity Securities, (ii) subdivide the outstanding Ordinary Shares
into a larger number of shares, (iii) combine the outstanding Ordinary Shares into a smaller number of shares, or (iv) issue any Company Equity Securities in a reclassification of the Ordinary Shares (other than any such event for which an
adjustment is made pursuant to another clause of this Section 4.7), then, and in each such case, the Conversion Price in effect immediately prior to such event shall be adjusted (and any other appropriate actions shall be taken by the Company)
proportionately so that the Holder shall be entitled to receive the number of Ordinary Shares or other securities of the Company that the Holder would have owned or been entitled to receive upon or by reason of the relevant event described above,
had this Note been converted immediately prior to the occurrence of such event or (if earlier) the record date for shareholders of the Company entitled to participate in such distribution. Any adjustment made pursuant to this Section 4.7(a)
shall become effective retroactively (x) in the case of any such dividend or distribution, to a date immediately following the close of business on the record date for the determination of holders of Ordinary Shares entitled to receive such
dividend or distribution, or (y) in the case of any such subdivision, combination or reclassification, to the close of business on the day upon which such corporate action becomes effective. 

  
 10 

  

	 	(b)	Issuance of Company Equity Securities below Conversion Price. 

  

	 	(i)	If the Company shall, at any time or from time to time, after the completion of an IPO but prior to conversion of this Note pursuant to Section 4.2(a), issue or
sell any Ordinary Shares or other Company Equity Securities (“New Securities”), other than an issuance in an Excluded Transaction, at a price per Ordinary Share that is less than the Conversion Price (treating the price per Ordinary
Share, in the case of the issuance of any Company Equity Securities other than Ordinary Shares, as equal to (x) the sum of the price for such Company Equity Securities plus any additional consideration payable (without regard to any
anti-dilution adjustments) upon the conversion, exchange or exercise of such Company Equity Securities, if any, divided by (y) the number of Ordinary Shares initially underlying such Company Equity Securities), then, and in each such case, the
Conversion Price in effect immediately prior to such issuance shall be adjusted by multiplying the Conversion Price in force immediately prior to such issue by the following fraction: 

A+B 
 C

 where: 
  

	 	A	shall mean the number of Ordinary Shares in issue (on a fully diluted and as converted basis) immediately prior to the issue of such New Securities;

  

	 	B	shall mean the number of Ordinary Shares which the aggregate consideration receivable by the Company for the issue of such New Securities would be able to purchase at
the Conversion Price per Ordinary Share; and 

  
 11 

  

	 	C	shall mean the number of Ordinary Shares in issue (on a fully diluted and as converted basis) immediately after the issue of such New Securities.

  

	 	(ii)	Such adjustment shall be made whenever such Ordinary Shares or Company Equity Securities are issued, and shall become effective retroactively (x) in the case of an
issuance to the shareholders of the Company to a date immediately following the close of business on the record date for the determination of shareholders entitled to receive such Ordinary Shares or Company Equity Securities and (y) in all
other cases, on the date of such issuance; provided, however, that the determination as to whether an adjustment is required to be made pursuant to this Section 4.7(b) shall be made upon the issuance of such Ordinary Shares or
Company Equity Securities, and not upon the issuance of any securities into which the Company Equity Securities are convertible or exchangeable or for which they may be exercised. 

 

	 	(iii)	In case at any time after the completion of an IPO but prior to conversion of this Note pursuant to Section 4.2(a), any Ordinary Shares or Company Equity
Securities or any rights or options to purchase any Ordinary Shares or Company Equity Securities shall be issued or sold (each, a “Future Subscription”) for cash, the consideration received therefor shall be deemed to be the amount
received by the Company therefor, without deduction therefrom of any expenses incurred or any underwriting commissions or concessions or discounts paid or allowed by the Company in connection therewith (collectively, “Expenses”). In
case of a Future Subscription for a consideration other than cash, the amount of the consideration other than cash received by the Company shall be deemed to be the fair market value of such consideration, without deduction therefrom of any
Expenses, as determined mutually by the board of Directors and the Majority Note Holders or, if the board of Directors and the Majority Note Holders shall fail to agree, by an independent appraiser chosen by the board of Directors, provided
that all costs and expenses associated with such appraisal shall be borne equally by the Company on the one hand and all Note Holders on the other hand. 

  

	4.8	Certificate as to Adjustments. The Company shall, within a reasonable period (not to exceed ten (10) Business Days) following any event requiring an
adjustment of the Conversion Price, deliver to the Holders a certificate, signed by a director of the Company, setting forth in reasonable detail the event requiring the adjustment and the method by which such adjustment was calculated and
specifying the Conversion Price in effect following such adjustment. 

  

	4.9	Indebtedness, Encumbrance. Until the entire Principal Amount of this Note and any other amounts payable in relation to this Note have been redeemed and paid
pursuant to Section 3 above or converted pursuant to Section 4.1 above, the Company shall not issue, assume, incur, become subject to, guarantee, amend the terms of, or suffer to exist any indebtedness or Encumbrance on any of its assets
without the prior written consent of the Majority Note Holders except for any indebtedness, guarantee or Encumbrance arising therefrom, incurred by the Company for working or operating capital purposes, including without limitation, any trade debts
or credit facilities. 

  
 12 

 SECTION 5 
 COVENANTS 
  

	5.1	Covenants. The Company covenants to the Holder that, from the date hereof until the entire Principal Amount of this Note have been redeemed and paid pursuant to
Section 3 above or converted pursuant to Section 4 above, the Company shall: 

  

	 	(a)	punctually pay the Principal Amount and/or any Interest payable on this Note, and any other amount due and payable under this Note in the manner specified in this Note;

  

	 	(b)	give written notice to the Holder of any Event of Default (as defined below) promptly upon the occurrence thereof; and 

 

	 	(c)	execute and deliver, or cause to be executed and delivered, upon the request of the Majority Note Holders and at the Company’s expense, such additional documents,
instruments and agreements as the Company and the Majority Note Holders may, each acting reasonably, mutually determine to be necessary to carry out the provisions of this Note and the Convertible Note Purchase Agreement and the transactions and
actions contemplated hereunder and thereunder. 

  

	5.2	No Dividend or Redemption. The Company covenants to the Holder that, from the date hereof until the earlier of its IPO or until all amounts owing hereunder have
been paid in full or this Note has been converted, the Company shall not, without the prior written consent of the Majority Note Holders, make any declaration or payment of dividends or other distributions, redemption or repurchase or any other
payment on or with respect to any Company Equity Securities other than the Notes.

	6.1	Events of Default. If any of the following events shall occur and be continuing:

hereof (such default, the “Payment Default”); 

  
 13 

  

	 	(b)	the Company shall default in the observance or performance of any of its covenant, condition or agreement under this Note (other than the Payment Default);

  

	 	(c)	except as approved by the board of Directors, any Key Manager shall have sold any of the Company Equity Securities held or beneficially owned by him/her, directly or

	 	(d)	either LIU Tianwen 

 or three out of the other seven Key Managers shall have ceased to be a full-time employee and officer of the Group Companies or otherwise ceased to perform management responsibilities or duties at the Group

at the Group Companies; 

  

	 	(e)	any Founder shall default in the observance or performance of any covenant, condition or agreement contained in any Transaction Agreement in any material respect, and
such default (i) cannot be cured, or (ii) can be cured but either remains uncured or has not been cured to the satisfaction of the Majority Note Holders twenty-one (21) days after being notified in writing of such default;

or 

  

	 	(h)	the occurrence of a Liquidation Event, 

 then, and in any such event (except events described in Section 6.1(d) that occur after the completion of an IPO of the Company), it shall constitute an “Event of Default”, and the
Company may be required by the Holder of this Note to redeem this Note as provided in Section 3.3. 
  

	6.2	Waiver of Event of Default. An Event of Default may be waived by approval of the Majority Note Holders or shall be deemed waived by a Holder if the Holder did
not exercise its right under Section 3.3 to require the Company to redeem the Note with respect to the Event of Default within six (6) months of the Holder’s receipt of a written notice to the Holder of any Event of Default pursuant
to Section 5.1(b) above. 

  
 14
