2. If there are concurrent sales of other smart bands, smart watches and smart scales on and through the sales platforms and channels operated by Party A (including the official website of Xiaomi (Mi.com), offline retail stores (Xiaomi Fans Club) and Mijia Youpin App on mobile), Party A undertakes that the Collaborative Products manufactured by Party B shall be displayed at a place with equal or better visibility.

Article 2: Product Development Capability of Party B

Party B shall possess the capability to develop independently, or to integrate relevant resources to develop the Collaborative Products. Party B shall be able to complete the development of any new products promptly should any Collaborative Product requires upgrade or should a new Collaborative Product is intended to fill a market gap.

1. Party A shall consult with Party B to determine the estimated launch date of any Collaborative Products taking into account the market need. Such consultation period shall commence from the date on which Party A notifies Party B and last for not more than sixty (60) calendar days. The Parties may extend the aforesaid consultation period depending on the circumstances.

2. Party B shall, within the period agreed upon by the Parties, complete the research and development as well as launch of products. If Party B fails to launch the products within such agreed period or the products fail to satisfy the requirements of Party A, Party A shall have the right to unilaterally terminate this Agreement and the relationship of this Strategic Collaboration.

Article 3: Product Quality Targets

Party B shall be responsible for the quality of the products to be delivered by it (including the products referred to under Article 1 hereof) and shall aim to achieve minimal defect rate by continuingly adjusting its production technics and methods to improve its product quality, competence and customer satisfaction. The specific quality targets are as follows:

Product Name	Performance Indicators	Target
Smart Bands	Market Repair Rate	<2%
Smart Watches	Market Repair Rate	<2%
Smart Scales	Market Repair Rate	<2%

Note: Market Repair Rate means the percentage of products that need to be repaired out of the total number of sold products during certain period due to product quality issues. For the avoidance of doubt, according to the local consumer protection regulation or return policy, products that are returned due to any reason other than product quality issues shall not be counted as the returned products for repair. The Market Repair Rate is calculated based on the after-sales data of Xiaomi.

Party A shall have the right to unilaterally terminate this Agreement and cease the said Strategic Collaboration if:

1) Party B fails to meet the quality targets provided under this Article for any three consecutive months; or

2) Material quality issue arises from products delivered by Party B which causes a massive product recall.
