ARTICLE VIII

INDEMNIFICATION

8.1 Indemnification by the Seller.
The Seller shall indemnify, defend and hold harmless the Buyer and its shareholders, directors, officers, employees, controlling persons, authorized agents, authorized representatives, successors and assigns (each an Indemnified
Party) from and after the Closing, from and against any and all losses, claims, damages, liabilities, obligations,



20



---

penalties, judgments, awards, costs, reasonable expenses and disbursements as incurred (and any and all actions, suits, proceedings and investigations in respect thereof and any and all
reasonable legal and other costs, reasonable expenses or disbursements in giving testimony or furnishing documents in response to a subpoena or otherwise), including, without limitation, the costs, reasonable expenses and disbursements, of
investigating, preparing or defending any such action, suit, proceeding or investigation (whether or not such Indemnified Party is a party) (together, Losses), directly or indirectly, caused by, relating to, based upon, arising
out of or in connection with:

(a) any breach by the Seller of any representation or warranty set forth in Article IV of this
Agreement (provided that the Seller is given written notice of such Loss); or

(b) any product shipped or manufactured by, or
any services provided by, any Acquired Company prior to the Closing Date.

The parties expressly agree that the Buyers
right to indemnification under this Section 8.1 shall not be limited by any knowledge obtained pursuant to any investigation conducted by or on behalf of the Buyer before or after the date of this Agreement.

8.2 Indemnification Procedures; Third Party Claims. An Indemnified Party shall give the Seller prompt written notice of any claim,
assertion, event or proceeding concerning any liability or damage as to which they may request indemnification from the Seller hereunder; provided, however, that any failure by an Indemnified Party to notify the Seller shall not
relieve the Seller from its obligations hereunder except to the extent the Seller is materially prejudiced by such failure and shall not relieve the Seller from any other obligation or liability that it may have to any Indemnified Party otherwise
than under this Article VIII. If the Seller so elects or is requested by an Indemnified Party, the Seller will assume the defense of such action or proceeding, including the employment of counsel reasonably satisfactory to such Indemnified Party and
the payment of the fees and expenses of such counsel. In the event, however, such Indemnified Party determines in the reasonable judgment of counsel that having common counsel would present such common counsel with a conflict of interest or
(i) other than in an action solely for monetary damages if the Seller fails to assume the defense of the action or proceed in a timely manner, (ii) if in the reasonable judgment of the Indemnified Party, the defense is being handled in
such a manner that Indemnified Partys reputation or future business prospects will be materially damaged or (iii) if a court of competent jurisdiction rules that the Seller has failed or is failing to prosecute or defend vigorously such
claim, then such Indemnified Party may employ separate counsel to represent or defend it in any such action of proceeding and the Seller will pay the fees and expenses of such counsel. In any action or proceeding the defense of which the Seller
assumes, the Indemnified Party will have the right to participate in such litigation and to retain its own counsel at such Indemnified Partys own expense.

The Seller agrees that, without the Buyers prior written consent, it will not settle, compromise or consent to entry of any judgment in any pending or threatened claim, action or proceeding in
respect of which indemnification could be sought under the indemnification provision of this Agreement (whether or not the Buyer or any other Indemnified Party is an actual or potential party to such claim, action or proceeding, so long as it is
reasonably likely that they could be named as a party), unless such settlement, compromise or consent includes and unconditional release of each Indemnified Party from all liability arising out of such claim, action or proceeding and does not
include a statement as to an admission of fault, culpability or a failure to act on behalf of an Indemnified Party.



21



---

8.3 Limitation on Indemnification. The indemnification provided for in Sections 8.1
and 8.2 shall be subject to the following limitations:

(a) The Seller shall not be liable for breaches of the representations
and warranties contained herein if and to the extent that the facts or circumstances which cause any of such representation and warranties to be breached were disclosed or referred to in the Disclosure Schedules;

(b) The Seller shall not be obligated to pay any indemnification to an Indemnified Party until the aggregate amount of all amounts payable
to the Indemnified Parties in respect of indemnification exceeds RMB500,000.00 (the Basket Amount). For the avoidance of doubt, the Basket Amount is not a deductible and if the aggregate amount for any indemnification exceeds the
Basket Amount, the Seller shall be obligated to pay the full amount of such aggregated indemnification;

(c) Notwithstanding
anything to the contrary in this Agreement, the aggregate indemnification payable by the Seller for the Losses of all Indemnified Parties in respect of all breaches of the representations and warranties herein and of any other provisions of this
Agreement shall in any event not exceed 75% of the Purchase Price; and

(d) Indemnification as provided in this Agreement
shall be the exclusive remedy that may be available to the Buyer under this Agreement.

ARTICLE IX

MISCELLANEOUS

9.1
Survival of Representations and Warranties. All representations and warranties of the Seller and the Buyer contained in Articles IV and V of this Agreement and all unasserted claims and causes of action with respect thereto shall survive for
12 months after the Closing Date except for those designated in the following sentence, which shall survive for the respective periods designated therein. The Sellers obligation under Section 4.14 shall survive the Closing until the
expiration of the statute of limitations (giving effect to any waiver, mitigation or extension thereof) on assessment of the relevant Tax.

9.2 Transfer Taxes. The Seller shall pay all sales, use, real property transfer, transfer, stamp, registration, documentary, recording, filing or similar transfer Taxes, if any, together with any
interest thereon, penalties, fines, costs, fees, additions to Tax or additional amounts with respect thereto (collectively, Transfer Taxes) incurred in connection with the issuance and sale of the Shares pursuant to this

or termination is sought.

9.5 Notices, etc. Except as otherwise provided in this Agreement, all notices and other
communications pursuant to this Agreement shall be in writing and shall be delivered in person, by courier, by facsimile transmission (with oral confirmation of receipt), by e-mail (so long as the sender receives no notice of non-delivery and the

the case may be) specified for the intended recipient in Disclosure Schedule 9.5, or to such other number or address as such recipient may have last specified by notice to the other parties. All such notices shall be effective upon receipt.

9.6 Dispute Resolution.

(a) Any dispute, controversy or claim arising out of or relating to this Agreement (including any provision of any Schedule or Exhibit thereto) or the interpretation, breach, termination or validity
hereof, shall be resolved through consultation. Such consultation shall begin immediately after one party hereto has delivered to the other parties hereto a written request for such consultation. If within 30 days following the date on which such
notice is given the dispute cannot be resolved, the dispute shall be submitted to arbitration upon the request of any party with written 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 Centre). There shall be three arbitrators. Each disputing
party shall select one arbitrator within 30 days after respectively 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 Centre shall select a third arbitrator to serve as presiding arbitrator within 30 days of the selection of the second arbitrator. The third arbitrator shall be qualified to practice New York State law. If any arbitrator has not been
appointed within the time limits specified herein, such appointment shall be made by the chairman of the Centre upon the written request of either party.

(c) The arbitration proceedings shall be conducted and the award shall be rendered in the English language. The arbitration tribunal shall apply the Arbitration Rules of the Centre in effect at the time
of the arbitration. However, if such rules are in conflict with the provisions of this Section 9.6, including the provisions concerning the appointment of arbitrators, the provisions of this Section 9.6 shall prevail.

(d) The hearing shall commence no later than 90 days following the appointment of the last of the three arbitrators and the award shall be
rendered no later than 30 days following the close of the hearing.

(e) The arbitrators shall decide any dispute submitted by the parties to the arbitration
strictly in accordance with the substantive law of the State of New York and shall not apply any other substantive law.

(f)
Consistent with the expedited nature of arbitration, each party will, upon the written request of the other party, provide the other with copies of documents relevant to the issue raised by any claim or counterclaim. Other discovery may be ordered
by the arbitrator to the extent the arbitrator deems additional discovery relevant and appropriate, and any dispute regarding discovery, relevance or scope thereof, shall be determined by the arbitrator, which determination shall be conclusive.

(g) The parties hereby waive any rights of application or appeal to any court or tribunal of competent jurisdiction
(including without limitation the courts of the United States, the British Virgin Islands, Hong Kong and PRC) to the fullest extent permitted by law in connection with any question of law arising in the course of the arbitration or with respect to
any award made except for actions relating to enforcement of the arbitration agreement or an arbitral award and except for actions seeking interim or other provisional relief in any court of competent jurisdiction.

(h) By agreeing to arbitration, the parties do not intend to deprive any court of its jurisdiction to issue a pre-arbitral injunction,
pre-arbitral attachment or other order in aid of arbitration proceedings and the enforcement of any award. Without prejudice to such provisional remedies in aid of arbitration as may be available under the jurisdiction of a national court, the
arbitral tribunal shall have full authority to grant provisional remedies and to award damages for the failure of any party to respect the arbitral tribunals orders to that effect.

(i) The award shall be final and binding upon the parties, and shall be the sole and exclusive remedy between the parties regarding any
claims, counterclaims, issues, or accounting presented to the arbitral tribunal. Judgment upon any award may be entered in any court having jurisdiction thereof.

(j) Subject to the receipt of any applicable governmental approval, any monetary award shall be made and promptly payable in U.S. Dollars free of any tax, deduction or offset, and the arbitral tribunal
shall be authorized in its discretion to grant pre-award and post-award interest at commercial rates. Any costs, fees, or taxes incident to enforcing the award shall, to the maximum extent permitted by law, be charged against the party resisting
such enforcement. The arbitral tribunal shall have the authority to award any remedy or relief proposed by each party pursuant to this Agreement, including without limitation, a declaratory judgment, specific performance of any obligation created
under this Agreement or the issuance of an injunction.

(k) This Agreement and the rights and obligations of the parties shall
remain in full force and effect pending the award in any arbitration proceeding hereunder.

the other in connection with the arbitration shall be in accordance with the provisions of Section 9.5 hereof.

CONFLICT OF LAWS.

9.8 Successors and Assigns. (a) No party to this Agreement may assign any of its rights or
obligations under this Agreement, without the prior written consent of the other parties hereto, except that a Buyer may assign its rights and obligations to one or more Affiliates of such Buyer, which shall agree in writing to be bound by the terms

9.10 Delays or Omissions. It
is agreed that no delay or omission to exercise any right, power or remedy on the part of any party upon any breach or default of any party to this Agreement shall impair any such right, power or remedy, nor shall it be construed to be a waiver of
any such breach or default, or any acquiescence therein, or of 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. It is further agreed that any waiver, permit, consent or approval of any kind or character on any party of any breach or default under this Agreement must be in writing and shall be effective only to the extent specifically set forth in
such writing and that all remedies either under this Agreement, or by law otherwise afforded to any party, shall be cumulative and not alternative.

9.13 Currency. (a) Subject to the receipt of any applicable Governmental Approval, all payments due to any party hereunder, other than payment for the Shares, shall be made and promptly
payable in U.S. Dollars free of any tax, deduction or offset. If for the purposes of making a payment required to be made hereunder it is necessary to convert all or any part of a sum due hereunder in any currency (the Original
Currency) into U.S. Dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which, in accordance with normal banking procedures, the Buyer could purchase the
Original Currency with U.S. Dollars, on the Business Day immediately preceding the day on which any such payment, or any relevant part thereof, is paid or otherwise satisfied.

(b) The obligation of the Seller in respect of any sum due hereunder in the Original Currency shall, notwithstanding any payment in U.S.
Dollars, be discharged only to the extent that on the Business Day following receipt by the Buyer of any sum adjudged to be so due in U.S. Dollars, the Buyer may, in accordance with normal banking procedures, purchase the Original Currency with U.S.
Dollars. If the amount of the Original Currency so purchased is less than the sum originally due to the Buyer in the Original Currency, the Seller shall, as a separate obligation and notwithstanding any such payment, indemnify the Buyer against such
loss, and if the amount of the Original Currency so purchased exceeds the sum originally due to the Buyer, the Buyer shall remit such excess to the Seller.

(c) All references to monetary amounts in this Agreement and the other transaction documents shall (unless specifically otherwise stated) mean such amounts as expressed in United States dollars.

9.14 Specific Performance. Without limiting the rights of each party hereto to pursue all other legal and equitable
rights available to such party for the other parties failure to perform their obligations under this Agreement, the parties hereto acknowledge and agree that the remedy at law for any failure to perform their obligations hereunder would be

circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the parties shall negotiate in good faith with a view to the substitution therefor of a suitable and equitable solution in order to carry out, so far as may be
valid and enforceable, the intent and purpose of such invalid provision, provided, however, that the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein
shall not be in any way impaired thereby, it being intended that all of the rights and privileges of the parties hereto shall be enforceable to the fullest extent permitted by law.
