Section 3.02 Issuance Notice    (a) In the event the Company proposes to undertake an issuance of Additional
Securities, it shall give each of the holders of the Ordinary Shares (except the Award Shares) and the Preferred Shares (a “Participation Right Holder”) a written notice (an “Issuance Notice”) of such intention,

Holder”) shall have the right to participate (on a pro-rata basis as among the Co-sale Eligible Holders and the Selling Shareholder) in the sale of such Offered Shares at the same price and subject to the same terms and conditions proposed
by a bona fide prospective purchaser. If the prospective purchaser refuses to purchase Equity Securities subject to the Right of Co-Sale from the Co-Sale Eligible Holders, no Selling Shareholder may sell any Offered Shares to such prospective
purchaser unless and until, simultaneously with such sale, such prospective purchaser purchases all Equity Securities subject to the Right of Co-Sale from the Co-Sale Eligible Holders.

Section 7.10 Delays or Omissions 

No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other
party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach
or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part
of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such
writing. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

this Agreement constitute the full and entire understanding and agreement between the Parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the Parties are
expressly cancelled. 
 Section 7.12 Dispute Resolution 

(a) Any dispute, controversy or claim arising out of or relating to this Agreement, or the interpretation, breach, termination or validity
hereof, shall first be subject to resolution through consultation of the Parties to such dispute, controversy or claim. Such consultation shall begin within seven (7) days after one Party hereto has delivered to the other Parties involved a
written request for such consultation. If within thirty (30) days following the commencement of such consultation the dispute cannot be resolved, the dispute shall be submitted to arbitration upon the request of any Party with notice to the
other Parties. 
 (b) The arbitration shall be conducted in Hong Kong under the auspices of the Hong Kong International Arbitration Centre
(the “HKIAC”). There shall be three (3) arbitrators. The complainant and the respondent to such dispute shall each select one arbitrator within thirty (30) days after giving or receiving the demand for arbitration. Such
arbitrators shall be freely selected, and the Parties shall not be limited in their selection to any prescribed list. The Chairman of the HKIAC shall select the third arbitrator, who shall be qualified to practice Law in Hong Kong. If either Party
to the arbitration does not appoint an arbitrator who has consented to participate within thirty (30) days after selection of the first arbitrator, the relevant appointment shall be made by the Chairman of the HKIAC. 

  
 24 

 (c) The arbitration proceedings shall be conducted in English. The arbitration tribunal shall
apply the Arbitration Rules of the HKIAC in effect at the time of the arbitration. However, if such rules are in conflict with the provisions of this Section 7.12, including the provisions concerning the appointment of arbitrators, the

 (d) The arbitrators shall decide any dispute submitted by the Parties to the
arbitration strictly in accordance with the substantive law of Hong Kong and shall not apply any other substantive law.

hereto shall cooperate with any party to the dispute in making full disclosure of and providing complete access to all information and documents requested by such Party in connection with such arbitration proceedings, subject only to any
confidentiality obligations binding on the Party receiving the request. 
 (f) The award of the arbitration tribunal shall be final and
binding upon the disputing parties, and any Party to the dispute may apply to a court of competent jurisdiction for enforcement of such award. 

(g) Any Party to the dispute shall be entitled to seek preliminary injunctive relief, if possible, from any court of competent jurisdiction
pending the constitution of the arbitral tribunal. 
 Section 7.13 Cumulative Rights    Each and all of the
various rights, powers and remedies of a Party will be considered to be cumulative with and in addition to any other rights, powers and remedies which such Party may have at law or in equity in the event of the breach of any of the terms of this
Agreement. The exercise or partial exercise of any right, power or remedy will neither constitute the exclusive election thereof nor the waiver of any other right, power or remedy available to such Party. 

Section 7.14 Further Assurance 

Each of the Parties hereto undertakes with each of the other Parties that it shall do, or shall procure to be done, all such acts and things
and shall execute, or shall procure to be executed, all such documents as may be necessary or appropriate to implement the provisions of this Agreement or otherwise to give full legal force and effect thereof. 

Section 7.15 Remedies. 

The Parties hereto, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to
specific performance of their rights under this Agreement. Each of the Parties agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agrees to
waive the defense in any action for specific performance that a remedy at law would be adequate. In addition, the rights of the Parties set forth in this Agreement shall be in addition to, and not in lieu of, any other rights that the Parties may
have in any capacity or otherwise. 
 Section 7.16 Conflict with the Restated Memorandum and Articles. 

In the event of any conflict or inconsistency between the provisions of this Agreement and the provisions of the Restated Memorandum and
Articles or other constitutional documents of the Company, the terms of this Agreement shall prevail as between the shareholders of the Company only. The Parties shall, notwithstanding the conflict or inconsistency, act so as to effect the intent of
this Agreement to the greatest extent possible under the circumstances and shall promptly amend the conflicting constitutional documents to conform to this Agreement to the greatest extent possible.

	4	OPERATION OF SCHEME 

  

	4.1	Subject to Paragraph 6, the Board may, from time to time, in its absolute discretion and subject to such terms and conditions as it may think fit (including the basis
of eligibility of each Employee determined by the Board from time to time) select an Employee (excluding any Excluded Employee) for participation in the Scheme as a Selected Employee and determine the number of Awarded Shares, provided that where
any Award is proposed to be made to any Selected Employee who is a director of the Company or a connected person of Kingsoft Corporation Limited and its subsidiaries, such Award must first be approved by the board of directors of Kingsoft
Corporation Limited as long as the Company remains a subsidiary of Kingsoft Corporation Limited. However, until so selected, no Employee shall be entitled to participate in the Scheme. Subject to the provisions of the Scheme, the Board may impose
any conditions, restrictions or limitations or waive any such conditions, restrictions or limitations from time to time in relation to the Award as it may at its absolute discretion think fit. Where a Selected Employee or his associate is a member
of the board of directors of Kingsoft Corporation Limited, such person will abstain from voting on any approval by the board of directors of Kingsoft Corporation Limited of an award of Shares to such Selected Employee. 

 

	4.2	Where any Award is proposed to be made to any Selected Employee who is a director of the Company or where the Board proposes to waive any conditions, restrictions or
limitations imposed on any Award made to any Selected Employee who is a director of the Company, or a connected person of Kingsoft Corporation Limited and its subsidiaries, such Award or waiver (as the case may be) must first be approved by the

be granted and to be bound by the rules of the Scheme. The Company shall, after having regard to the requirement under Paragraph 4.11, cause the Consideration to be paid to the Trustee as soon as practicable. 

  
 - 7 -

	4.4	Within twenty (20) Business Days (or such other period as the Trustee and the Company may agree from time to time having regard to the circumstances of the
purchase concerned) after receipt of the Consideration, the Trustee shall apply the same towards the purchase of the Awarded Shares. The Shares so purchased shall form part of the trust fund of the Trust. 

 

	4.5	Unless otherwise determined by the Board at its discretion, the Awarded Shares held by the Trustee upon the Trust and which are referable to a Selected Employee shall
vest in that Selected Employee in accordance with the Award Notice, provided that the Selected Employee remains at all times after the Reference Date and on the relevant vesting dates (if applicable) an Employee. Notwithstanding any other provision
of these rules of the Scheme and the terms and conditions of any Award, the Board (or where the relevant Selected Employee is a director of the Company, or a connected person of Kingsoft Corporation Limited and its subsidiaries, the board of
directors of Kingsoft Corporation Limited as long as the Company remains a subsidiary of Kingsoft Corporation Limited) in its sole and absolute discretion may determine from time to time on a general or case by case basis that an Award may be vested
at such time determined by the Board (or the board of directors of Kingsoft Corporation Limited, as the case may be) subsequent to and notwithstanding a termination of employment of a Selected Employee (including but not limited to as a result of
the Selected Employee’s retirement or death). The date or each such date on which the Awarded Shares are to vest is hereinafter referred to as a “Vesting Date”. 

 

	4.6	Save as provided in Paragraph 4.5, in the event (i) a Selected Employee ceases to be an Employee, or (ii) the company by which a Selected Employee is employed
ceases to be a member of the Group, or (iii) an order for the winding-up of the Company is made or a resolution is passed for the voluntary winding-up of the Company (otherwise than for the purposes of an amalgamation, reconstruction or scheme
of arrangement) (each of these, an event of “Lapse”), an Award shall automatically lapse forthwith and all the Awarded Shares shall not vest on the relevant Vesting Date but shall become Returned Shares for the purposes of the
Scheme. The Selected Employees shall have no claims against the Company or the Trustee. 

  

	4.7	In the event a Selected Employee is found to be an Excluded Employee (an event of “Partial Lapse”), the relevant part of an Award made to the relevant
Selected Employee shall automatically lapse forthwith and the relevant Awarded Shares shall not vest on the relevant Vesting Date but shall become Returned Shares for the purposes of the Scheme. The Selected Employees shall have no claims against
the Company or the Trustee. 

  

	4.8	Save for a Lapse or Partial Lapse, barring any unforeseen circumstances and subject to the receipt by the Trustee of a confirmation from the Company that all vesting
conditions having been fulfilled, the Trustee shall effect the transfer of the relevant Awarded Shares to the relevant Selected Employee on the Vesting Date, or as soon as possible thereafter if it is not practicable to effect such transfer on such
Vesting Date. 

  
 - 8 -

	4.9	Any Award made hereunder shall be personal to the Selected Employee to whom it is made and shall not be assignable and no Selected Employee shall in any way sell,
transfer, assign, charge, mortgage, encumber or create any interests in favour of any other third party over or in relation to either the Reference Amount or the Awarded Shares referable to him pursuant to such Award or any of the Returned Shares
under the Scheme. 

  

	4.10	For the avoidance of doubt, 

  

	 	(a)	a Selected Employee shall only have a contingent interest in the Awarded Shares which are referable to him subject to the vesting of such Shares in accordance with

	 	(b)	the date when an order for the winding up of the Company is made or a resolution is passed for the voluntary winding-up of the Company (otherwise than for the purposes
of an amalgamation, reconstruction or scheme of arrangement); and 

  

	 	(c)	such date of early termination as determined by the Board.

	10	MISCELLANEOUS 

  

	10.1	The Scheme shall not form part of any contract of employment, service contract or engagement contract between the relevant member of the Group and any Selected
Employee, and the rights and obligations of any Selected Employee under the terms of his office, employment, appointment or engagement shall not be affected by his participation in the Scheme or any right which he may have to participate in it and
the Scheme shall afford such a Selected Employee no additional rights to compensation or damages in consequence of the termination of such office, employment, appointment or engagement for any reason. 

 

	10.2	The Trustee in its absolute discretion may at any time apply any Residual Cash to defray the costs of establishing and administering the Scheme, including, for the

registration fee (i.e. not being fee chargeable by the share registrar of an express service of registration) in respect of, and other costs, liabilities or expense which may arise as a result of, the transfer of or agreement to transfer Shares to a
Selected Employee on the relevant Vesting Date, or which may otherwise arise out of the administration of the trust fund of the Trust. To the extent such application of Residual Cash is not sufficient to fund all such fees, costs and expenses, the
Company will provide the Trustee with the shortfall amount to settle such fees, costs and expenses upon demand by the Trustee. For the avoidance of doubt, the Company shall not be liable for any tax, costs or expenses of any other nature payable on
the part of any Selected Employee in respect of any award, sale, purchase, vesting or transfer of Shares, and the Selected Employee shall be liable therefor. 

 

	10.3	Save as specifically provided herein, the Scheme shall not confer on any person any legal or equitable rights (other than those constituting and attaching to the Shares
themselves) against the Company directly or indirectly or give rise to any cause of action at law or in equity against the Company.

of the Company, its registered office in Cayman Islands or such other address as notified to the Selected Employee from time to time and in the case of a Selected Employee, his address as notified to the Company from time to time. Any notice or
other communication served by post shall be deemed to have been served 24 hours after the same was put in the post. 

  
 - 11 -

	10.5	The Company shall not be responsible for any failure by any Employee to obtain any consent or approval required for such Employee to participate in the Scheme as a
Selected Employee or for any tax, duty, expenses, fees or any other liability to which he may become subject as a result of his participation in the Scheme. 

 

	10.6	Each and every provision hereof shall be treated as a separate provision and shall be severally enforceable as such and in the event of any provision or provisions
being or becoming unenforceable, they shall be deemed to be deleted from these rules of the Scheme, and any such deletion shall not affect the enforceability of the rules of the Scheme as remain not so deleted. 

 

	11	GOVERNING LAW, ETC. 

  

	11.1	The Scheme shall operate subject to the articles of association of the Company from time to time and any applicable law, regulations, rules and codes.
