Amount of the Deposit in immediately available funds to a bank account of the Deposit Receiver designated by the Company, provided that the Company shall deliver the wire instructions to Baidu Online at least five (5) Business Days prior

 (iii) Surrender and Re-issuance of the Purchased Share; Exercise of the
Warrant. Each of Baidu Online and Baidu SPV shall procure the Designated Warrant Holder to, as soon as possible, submit all necessary documents that are required to complete the requested registrations and filings and to obtain the relevant
approvals from the competent Governmental Authorities of the PRC with respect to the outbound direct investment by the Designated Warrant Holder into the Company (all such registrations, filings and approvals, the “Outbound Investment
Approvals”). For the avoidance of doubt, the Outbound Investment Approvals shall include all the necessary registrations or procedures that are necessary for the Designated Warrant Holder to remit the relevant investment fund outside of PRC
to the Company Bank Account). Without prejudice to the generality of the foregoing, each of Baidu Online and Baidu SPV shall procure that the total investment amount for which the Designated Warrant Holder applies in connection with its investment
in the Company through the Outbound Investment Approvals shall be denominated in U.S. dollars and equal to the Investment Amount. Each Party hereby acknowledges that the Designated Warrant Holder may pay the Warrant Aggregate Exercise Price in one
or more tranches and apply for Outbound Investment Approvals in respect of each tranche of such payment. In the event the Outbound Investment Approvals in respect of any tranche of the payment for the Warrant Aggregate Exercise Price are obtained:

 (a) no later than ten (10) Business Days after obtaining such Outbound Investment Approvals, Baidu Online shall procure that the
Designated Warrant Holder shall serve a written notice (the “Outbound Investment Notice”) to the Company and the Deposit Receiver with reasonable details (x) evidencing its procurement of the Outbound Investment Approvals (by
attaching copies of the Outbound Investment Approvals); and (y) describing the approved quota amount of outbound direct investment by the Designated Warrant Holder in the Company under such Outbound Investment Approvals which is outstanding at
the time of issuance of the Outbound Investment Notice (such approved quota amount set out in the Outbound Investment Notice, the “Approved Quota Amount”), which shall not exceed the Investment Amount. 

(b) the Designated Warrant Holder shall be entitled to exercise the Warrant and to receive, and to request the Company to issue, such number
of Warrant Shares that equals: (x) the Approval Quota Amount as set out in the relevant Outbound Investment Notice, divided by (y) the Warrant Per-Share Exercise Price, provided that, such Warrant
Shares will be issued upon the payment of the relevant Warrant Exercise Price by the Designated Warrant Holder in accordance with the time and manner as prescribed under Section 2.3(iv)(b) below. 

  
 14 













 (c) in the event that the Warrant is only partially exercised by the Designated Warrant
Holder in accordance with Section 2.3(iii)(b) above, Baidu SPV shall be entitled to, at its sole discretion, reserve its Series F-2 Preferred Share, or surrender the Series F-2 Preferred Share held by it to the Company at no consideration and request the Company to simultaneously re-issue one fully-paid Series F-2 Preferred Share (hereinafter the
“Re-Issued F-2 Preferred Share”) to the Designated Warrant Holder. For the avoidance of doubt, against the
re-issuance of the Re-Issued F-2 Preferred Share, the surrender of the Series F-2
Preferred Share held by Baidu SPV shall be deemed as the consideration therefor and neither Baidu SPV nor the Designated Warrant Holder needs to pay any further consideration to the Company. 

(d) the Company and each other Party undertake to cooperate with and assist, and undertake to procure that each of the then shareholders of
the Company to cooperate with and assist in completing, if elected by Baidu SPV, the surrender of the Series F-2 Preferred Share held by Baidu SPV, the re-issuance of the
Re-Issued F-2 Preferred Share, and/or the exercise of the Warrant in accordance with terms thereunder, including without limitation, executing any and all necessary
agreements and documents to approve such transactions, waiving any pre-emptive right, right of first refusal, anti-dilution rights and any other similar rights. 

For the avoidance of doubt, if the Designated Warrant Holder elects to pay the Warrant Aggregate Exercise Price in tranches and obtains the
Outbound Investment Approvals in respect of any such tranche, the procedure set forth in Sections 2.3(iii)(a) to (d) shall apply mutatis mutandis. 

(iv) Repayment of the Deposit and Warrant Holder’s Payment. 

(a) Repayment of the Deposit. Subject to Section 2.3(iv)(c) below, upon receipt of any Outbound Investment
Notice, the Deposit Receiver shall, and the Company shall cause the Deposit Receiver to repay the Deposit in an amount (the “Repayable Deposit Amount”) equal to the product of the Total Deposit Amount multiplied by a fraction, i)
the numerator of which is the Approved Quota Amount as set out in such Outbound Investment Notice; and ii) the denominator of which is the Investment Amount. The Repayable Deposit Amount shall be repaid as follows: 

(x) in the event that the Repayable Deposit Amount is no more than one third (1/3) of the Total Deposit Amount, the Deposit Receiver shall
repay the Repayable Deposit Amount to the Deposit Provider, in a lump sum, within two (2) months from receipt of the relevant Outbound Investment Notice; and 

(y) in the event that the Repayable Deposit Amount is more than one third (1/3) of the Total Deposit Amount, the Deposit Receiver may choose
to (i) repay the Repayable Deposit Amount in a lump sum within six (6) months from receipt of the relevant Outbound Investment Notice; or (ii) repay the Repayable Deposit Amount to the Deposit Provider in instalments, provided that

the previous installment(s); and (bb) the first installment should be made within two (2) months from the receipt of the relevant Outbound Investment Notice and the interval between any two installments shall not be longer than two
(2) months. 

  
 15 













 (b) Payment of Warrant Exercise Price. After the Deposit Receiver repays any
Repayable Deposit Amount in accordance with Section 2.3(iv)(a), each of Baidu Online and Baidu SPV shall procure that the Designated Warrant Holder shall pay, or cause its designated Affiliate to pay, in U.S. dollars in
immediately available funds, relevant Warrant Exercise Price in an amount equal to the product of the Warrant Aggregate Exercise Price multiplied by a fraction, i) the numerator of which is the amount of such Repayable Deposit Amount that has been
repaid by the Deposit Receiver, and ii) the denominator of which is the Total Deposit Amount, to the Company Bank Account within ten (10) Business Days after receipt of relevant Repayable Deposit Amount. Upon the afore-mentioned payment of the
relevant Warrant Exercise Price, the Company shall (i) issue such number of Series F-1 Preferred Shares to the Designated Warrant Holder as calculated by dividing the Warrant Exercise Price paid by
Designated Warrant Holder under this Section 2.3(iv)(b) by Warrant Per-Share Exercise Price, and (ii) deliver to the Designated Warrant Holder (x) a true copy of the
Company’s updated register of members of the Company certified by the corporate secretary of the Company, reflecting the Designated Warrant Holder’s ownership of such Series F-1 Preferred Shares,

(c) If the Designated Warrant Holder fails to pay the Warrant Exercise Price in accordance with Section 2.3(iv)(b),
the Company may issue a written notice to the Designated Warrant Holder requesting the immediate payment of the relevant Warrant Exercise Price, and if the Designated Warrant Holder still fails to make the relevant payment within twenty
(20) Business Days after receipt of relevant Repayable Deposit Amount, (1) the Company shall be entitled to forfeit the right under the Warrant to purchase such number of Warrant Shares that equals (x) the Warrant Exercise Price that
the Designated Warrant Holder fails to pay, divided by (y) the Warrant Per-Share Exercise Price, and (2) if the Company selects not to forfeit the right under the Warrant to purchase such number of
Warrant Shares, the Deposit Receiver shall be entitled to suspend repayment of any Repayable Deposit Amount upon receipt of any subsequent Outbound Investment Notice in accordance with Section 2.3(iv)(a), unless and until
the Designated Warrant Holder makes payment of the payable Warrant Exercise Price with respect to which the Designated Warrant Holder has failed to pay in accordance with Section 2.3(iv)(b) or equivalent U.S. dollars have
been paid to the Company Bank Account by any Person designated or on behalf of such Designated Warrant Holder. For the avoidance of doubt, (1) upon the payment by the Designated Warrant Holder of the payable Warrant Exercise Price with respect
to which the Designated Warrant Holder has failed to pay in accordance with Section 2.3(iv)(b) or equivalent U.S. dollars have been paid in accordance with this Section 2.3(iv)(c), the Company
shall issue such number of Series F-1 Preferred Shares to and deliver such documents to the Designated Warrant Holder in accordance with Section 2.3(iv)(b) the same way as if the
Warrant Exercise Price had been paid in accordance with Section 2.3(iv)(b), (2) the Company’s forfeiture of the right under the Warrant to purchase the relevant Warrant Shares in accordance with the foregoing sentence
shall not affect any portion of the Warrant Shares that any Designated Warrant Holder has purchased or are not represented by such unpaid Warrant Exercise Price, and (3) the Deposit Receiver’s right to suspend the repayment of any
Repayable Deposit Amount in accordance with the foregoing sentence shall not affect any other obligation of the Deposit Receiver hereunder or under the Deposit Agreement to repay the Deposit. 

  
 16 













 (d) Nothing set forth under this Section 2.3 shall be interpreted
as indicating that the Warrant may only be exercised after the Outbound Investment Approvals are obtained. If the Warrant is assigned by the Designated Warrant Holder to one or more Warrant Assignee(s) (each, an “Eligible Warrant
Assignee”) in accordance with the terms thereunder with respect to whom the PRC laws relevant to outbound direct investment are not applicable, then the Eligible Warrant Assignee(s) shall be entitled to exercise all or any portion of the
Warrant at any time after the assignment and receive all or portion of the Warrant Shares by paying the Company the Warrant Per-Share Exercise Price for each such Warrant Share in U.S. dollars. If any Eligible
Warrant Assignee proposes to exercise the Warrant in accordance with this Section 2.3(iv)(d), it shall serve a written notice of such fact to the Deposit Receiver, which shall set out the number of Warrant Shares it will
acquire pursuant to the exercise of the Warrant. After receipt of the foregoing notice, the Deposit Receiver shall repay to the Deposit Provider, the Deposit in Renminbi in an amount equal to the product of the Total Deposit Amount multiplied by a
fraction, (x) the numerator of which is such number of the Warrant Shares that is set out in the foregoing written notice, and (y) the denominator of which is the maximum number of Warrant Shares issuable under the Warrant (which shall,
for the avoidance of doubt, equal to the Investment Amount, divided by the Warrant Per-Share Exercise Price), as soon as practicable prior to such Eligible Warrant Assignee’s payment of the relevant
Warrant Exercise Price and in no event later than two (2) months after the receipt of such notice. 
 2.4 Accelerated Issuance.

 (a) Upon the occurrence of a Redemption Event or a Liquidation Event as defined in the Shareholders Agreement, if any rights,
preferences and privileges of the holder of the Series F-2 Preferred Share under the Shareholders Agreement and the Memorandum and Articles cannot be achieved due to the statutory requirements under any
applicable laws, Warrant Holder shall be entitled to exercise the portion of Warrant held by it by paying the relevant Warrant Exercise Price in the form of issuing a promissory note at nil consideration, free of any interest, to the Company with a
principal amount equal to the Warrant Exercise Price payable by such Warrant Holder (which principal amount shall be adjusted in accordance with the immediate below paragraphs (b) and (c)) and the Company shall issue the Warrant Holder such
number of Warrant Shares that equals (x) the relevant Warrant Exercise Price, divided by (y) the Warrant Per-Share Exercise Price. The Parties agree that, upon the issuance of such promissory note,
any and all of the afore-mentioned Warrant Shares shall be credited as fully paid and non-assessable and the relevant holder of Series F-1 Preferred Shares shall be
entitled to receive the relevant redemption price or liquidation amount that it is entitled to by reason of holding such Series F-1 Preferred Shares in accordance with the Memorandum and Articles. 

  
 17 













 (b) Sections 12.5 and 12.6 of the Shareholders Agreement shall be applied
mutatis mutandis to the payment of the liquidation amount and the redemption price, provided that the U.S. dollars equivalent of the relevant refunding of the Deposit shall be deemed to be the principal amount of the promissory note as
provided in Section 2.4(a) (and also the relevant Warrant Exercise Price). Upon the deduction of the principal amount from the relevant redemption price or the liquidation amount, the promissory note shall be deemed as
fully paid by the Warrant Holder. 
 (c) Notwithstanding the above, if the relevant liquidation amount distributable to such Warrant Holder
in accordance with the Memorandum and Articles after it receives the Warrant Shares referred to in Section 2.4(a) is less than the principal amount of the promissory note issued by such Warrant Holder to the Company in
accordance with Section 2.4(a), the relevant Warrant Exercise Price for acquisition of the foregoing Warrant Shares and the principal amount of such promissory note shall be adjusted and reduced automatically to the
relevant liquidation amount distributable to the Warrant Holder, and the Company hereby agrees that the Warrant Holder shall not be obliged to repay any principal amount of the promissory note or Warrant Exercise Price once such amount is set off
against the relevant liquidation amount distributable to the Warrant Holder according to the Memorandum and Articles upon any Liquidation Event. 

2.5 Early Exercise of Warrant. Notwithstanding anything to the contrary, prior to the Designated Warrant
Holder’s procurement of the Outbound Investment Approvals for the entire Investment Amount, upon the Company’s initiating of the procedures for launching an IPO (as defined in the Shareholders Agreement) being duly approved by the Board in
accordance with the Shareholders Agreement or immediately upon the second anniversary of the Closing, whichever is earlier, the Designated Warrant Holder shall assign the Warrant to one or more Eligible Warrant Assignees (which Eligible Warrant
Assignees shall be approved by the Company in the case of an IPO) and the Eligible Warrant Assignees shall exercise the Warrant to pay the Warrant Exercise Price in U.S. dollars, provided that such assignment shall not affect the IPO in any adverse
manner. The Deposit Receiver shall repay to the Deposit Provider, the outstanding amount of the Deposit in Renminbi in accordance with Section 2.3(iv)(d) upon the assignment of the Warrant. 

2.6 No Liability. If the Designated Warrant Holder fails to pay any Warrant Exercise Price as a result of the Deposit
Receiver’s failure to fully repay the relevant Repayable Deposit Amount in accordance with this Agreement and the Deposit Agreement, the Designated Warrant Holder shall not be held liable for the
non-payment of such Warrant Exercise Price. The Company hereby irrevocably waives its first and paramount lien provided in the Memorandum and Articles on any Series F Preferred Shares issued to the Designated
Warrant Holder pursuant to Section 2.3(iii) if the Designated Warrant Holder fails to pay the Warrant Exercise Price for such Warrant Shares as a result of the Deposit Receiver’s failure to repay the relevant Repayable
Deposit Amount. 
 2.7 Assignment. Upon any assignment of the Warrant (to the extent not exercised) in part or in full in
accordance with the terms of the Warrant, the assignee (the “Warrant Assignee”) shall execute a joinder agreement in form and substance to the reasonable satisfaction of the Company to become a party hereto and, in respect of the
portion of the Warrant assigned to it, enjoy and be bound by the rights and obligations under this Agreement applicable to it as a Party, as an Investor and as a Warrant Holder.

10.9 Amendments. Any term of this Agreement may be amended, only with the written Consent of the Company and the Series F
Investors. Any amendment effected in accordance with this paragraph shall be binding upon each of the Parties hereto. 
 10.10
Severability. In case any provision of the Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. If, however,
any provision of this Agreement shall be invalid, illegal, or unenforceable under any such applicable Law in any jurisdiction, it shall, as to such jurisdiction, be deemed modified to conform to the minimum requirements of such Law, or, if for any
reason it is not deemed so modified, it shall be invalid, illegal, or unenforceable only to the extent of such invalidity, illegality, or limitation on enforceability without affecting the remaining provisions of this Agreement, or the validity,
legality, or enforceability of such provision in any other jurisdiction. 
 10.11 Waiver. Any waiver must be in writing
and shall be effective only to the extent specifically set forth in such writing. No delay or omission to exercise any right, power or remedy accruing to any Warrantor or the Series F Investors, upon any breach or default of any party hereto under
this Agreement, shall impair any such right, power or remedy of such Warrantor or the Series F Investors, nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of any similar breach of default
thereafter occurring; nor shall any waiver of any other breach or default theretofore or thereafter occurring. 
 10.12 Headings
and Subtitles; Interpretation. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement. The rule of construction to the effect
that ambiguities are to be resolved against the drafting party shall not be employed in interpreting this Agreement and the other Transaction Documents. 

10.13 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument. Facsimile, PDF, e-mailed or other electronic copies of signatures shall be deemed to be originals for purposes of the
effectiveness of this Agreement.

 10.14 Specific Performance. Each of the Parties hereto acknowledges and agrees
that a breach of this Agreement would cause irreparable damage to each Investor and that each Investor will not have an adequate remedy at Law. Therefore, the obligations of the Warrantors under this Agreement shall be enforceable by a decree of
specific performance issued by any court of competent jurisdiction, and appropriate injunctive relief may be applied for and granted in connection therewith. Such remedies shall, however, be cumulative and not exclusive and shall be in addition to
any other remedies which any party may have under this Agreement or otherwise. 
 10.15 Independent Nature of Investors’
Obligations and Rights. The purchase of the Series F Preferred Shares by each of the Series F Investors at the Closing as set forth in Section 2 shall be a separate and independent transaction and may be consummated or
terminated separately and severally in accordance with the terms of this Agreement. The obligations of each Investor under this Agreement are several and not joint, and no Investor is responsible in any way for the performance or conduct of any
other Investor in connection with the transactions contemplated hereby. Nothing contained herein and no action taken by any Investor pursuant hereto, shall be or shall be deemed to constitute a partnership, association, joint venture, or joint group
with respect to the Investors. Each Investor agrees that no other Investor has acted as an agent for such Investor in connection with the transactions contemplated hereby.
