Buyer a *** grace period, during which Buyer will be excused from default liability unless Buyer fails to make the full payment for the original supply volume, provided that Seller is entitled to refuse to deliver the Products before it receives the

	8.1.1	If Buyer fails to make timely Payment according to Article 3.5 in the absence of Seller’s breach and such payment is delayed for *** or more (the Buyer is entitled to a grace
period of ***), it shall be deemed that Buyer has waived its right to purchase the relevant Products in connection with the delayed payment. However, if Buyer’s payment delay is shorter than ***, then it has the right to make payment and demand

Seller, and Buyer is entitled to terminate this Agreement. If Seller’s delivery delay or supply shortfall does not constitute a material breach, or if Seller’s delivery delay or supply shortfall constitute a material breach but Buyer
chooses to continue to perform this Agreement, Seller shall pay Buyer a penalty according to this Article. If Seller materially breaches this Agreement, Buyer may choose not to terminate this Agreement but claim a penalty against Seller pursuant to
Article 8.2.1 for no more than *** (or a shorter period if the remaining Term of this Agreement is shorter than ***), except when this Agreement is terminated by an effective legal instrument. 

  

	8.2.2	If Seller materially breaches this Agreement and Buyer chooses to terminate this Agreement: 

  

	 	(a)	Seller shall be subject to a penalty pursuant to Article 8.2.1 of this Agreement (for no more than *** or a shorter period if the remaining Term of this Agreement is shorter than
***), AND 

  

	 	(b)	Seller shall pay Buyer a liquidated damages equivalent to***. 

  

	8.3.1	 Both Parties agree and confirm that the Parties foresee the Losses which may potentially be caused by breach of this Agreement at the time of executing this

Parties hereby agree to waive their rights to adjust the amount of liquidated damages pursuant to Article 114 of the Contract Law of the People’s
Republic of China, where such liquidated damages exceed the actual Losses. 

  

	8.3.2	If any Product infringes any intellectual property right of a PRC third party and Buyer suffers from infringement claims in relation thereto, Seller shall indemnify Buyer for its
losses in connection thereto. If any Products infringe any intellectual property right of a person located in Germany, Spain or Italy and Buyer suffers from infringement claims in relation thereto, Seller shall indemnify Buyer for its loss in
connection thereto, provided that such indemnification is caped by the total Price of the Products delivered under this Agreement and actually used in Buyer’s infringing products. 

 Buyer shall notify Seller within *** from the occurrence of the above incident. Seller has the rights to participate in any related negotiations,
discussions, litigations etc. and to exercise its rights of defense and counterclaim. Buyer shall cooperate with Seller to resolve the disputes and avoid any actions that could harm the interest of Seller during the dispute resolution. If Buyer
violates the abovementioned covenant and causes Losses to Seller, Buyer should compensate Seller accordingly. 
  

	8.4	Termination and Rescission 

  

	8.4.1	This Agreement shall be terminated upon the occurrence of any of the following events: 

  

	 	(a)	Expiration of the Term of this Agreement; or 

  

	 	(b)	Termination by written agreement between the Parties. 

  

	8.4.2	This Agreement may be unilaterally terminated by a Party through written notice to the other Party, upon the occurrence of any of the following events: 

  

	 	(a)	the non-breaching Party may terminate this Agreement by notifying the breaching Party in writing when Seller commits a material breach under Article 8.2;

other Party may unilaterally terminate this Agreement by notifying such Party in writing; 

  

	 	(c)	if Seller fails to make timely delivery of or fails to deliver the Product in the agreed volume for *** in addition to claiming a penalty according to Article 8.2.1, Buyer may also
terminate this Agreement; or 

  

	 	(d)	if Buyer fails to make payment according to Article 3.5 for ***, Seller may terminate this Agreement.
