OUR CORE TECHNOLOGIES CORE TECHNOLOGIES LBT Lightweight Body Technology AIT Accurate Installation Technology MST Mirror Surface Technology SBT Super Boost Technology TBT Thermostat Battery Technology DTT Dynamic Torque Technology 23

Composite Material Reinforcement Technology 24 LBT Lightweight Body Technology OUR CORE TECHNOLOGIES Lightweight Body Technical Features: 1 Use of aluminum alloy and composite materials to replace the traditional steel body. Such light weight designs reduce energy consumption for the same driving range, which decreases the units of battery mounted in our vehicles, thereby contributing to lowered sales prices of our vehicles. 2 With the easy formability characteristic of aluminum alloy materials, through appropriate extrusion and casting methods, a complex mechanical structure can be formed at one time (traditional metal stamping requires multiple steps), thereby greatly reducing the body weight and the number of parts. 3 Fewer parts and components, thereby improving the production efficiency and reducing manufacturing costs. 4 According to different materials and structural characteristics, different connection types such as welding, flow drill screws (FDS) and self - piercing riveting (SPR) are adopted in a targeted manner, thereby improving the manufacturing quality and reliability of products. 5) We can effectively strengthen the parts that are under high forces and mechanical tensions, by applying a variety of composite material reinforcement technologies.

Technical Features: 1) Core Components: composite parts + adjustable nuts. 2) Adjustable transition piece between the exterior part and the body . The utilization of the adjustable transition joints guarantees the accurate installation of the exterior parts even if measurement deviations exist . 3) Process Overview : Grab the composite material parts with the robotic arm ; scan the parts online through the blue light ; record the deviation of the parts ; locate the parts in the correct installation position ; install them with the body through the adjustable nut . Self - positioning System (Blue Light Scanning) AIT Accurate Installation Technology 25 OUR CORE TECHNOLOGIES

Technical Features: With steel sheet metal bodies, traditional automobiles have serious problems including heavy structure, poor appearance quality, high maintenance costs and dysfunction of forming sophisticated shapes. We innovated the multilayer composite material technology combined with polycarbonate (PC) material, making full use of the benefits of PC to generate optical surface and super - strength steel structures. To solve the common problems of aging, wearing, thermal deformation, our products have the following advantages: 1) Low cost and lightweight; 2) Mirror - grade body surface; 3) One - time molding of complex profiles (high degree of freedom of modeling); 4) High strength, not easily damaged by collision, easy to repair and replace; and 5) Produced without spray applications. Dual Color Injection Molding Process 26 MST Mirror Surface Technology OUR CORE TECHNOLOGIES

Technical Features: We optimize the performance of electric machinery and battery by moderating temperature, capacity and other parameters of the motor battery through a vehicle control unit (VCU), which provides drivers with a satisfying driving experience. Our super boost technology offers a launch control mode and powerful straight - line acceleration suitable for auto racing. Meanwhile, the technology also guarantees the safety of the electric machinery and battery. 27 OUR CORE TECHNOLOGIES (Cont’d) SBT Super Boost Technology

Technical Features: The following functions can be realized via intelligent temperature controls: 1) Extending the longevity of lithium - ion batteries; 2) Improving the charge - discharge performance of lithium - ion batteries at low temperatures; 3) Improving the cruising range of lithium - ion batteries at low temperatures; and 4) Improving the safety of lithium - ion batteries and avoid thermal runaway. Core Technology: 1) Power battery pre - cooling and pre - heating technology; and 2) Power battery insulation technology. Standardized Battery Box: 1) Prolong the battery endurance and slow the depreciation of the battery - --- reduce the possibility of battery decay. The efficiency of the battery will not rapidly decline due to a thermostat system with liquid working fluid; 2) Address common battery safety problems including potential fire risks; electrical safety K50 System 10 Cells K20 System Single Unit Battery TBT Thermostat Battery Technology OUR CORE TECHNOLOGIES (Cont’d) measures meets the ISO standard 26262; 28 3) Reduce the cost of battery development, production and operation; and 4) Ameliorate battery maintenance service ---- simplify the process of diagnosis, fault - tolerance, maintenance and replacement under standardization.

Technical Features: In traditional vehicles, the ESP system usually applies reverse braking forces to the wheels to counteract understeer and oversteer handling during dynamic driving to correct vehicles‘ postures. However, this method affects vehicles both in speed and drivability. The advantage of electric vehicles is their distributed motors can drive the front and rear wheels independently. The motors can generate both strong driving forces and strong braking forces in the opposite direction on different wheel axles at the same time. By collecting various dynamic index signals of the vehicle (such as lateral acceleration, yaw rate), our sports vehicles use a comprehensive algorithm controlling the VCU module in order to implement dynamic torque distribution.

38 MANUFACTURING

The construction of Qiantu's factory began in 2016 and it officially obtained the national new energy passenger vehicle production qualification in 2016 from the National Development and Reform Commission . Initially, it covered an area of 230 , 000 square meters with an initial planned capacity of 50 , 000 cars/year . The plant does not have the stamping and painting workshops required in the traditional four processes (stamping, welding, painting and final assembly workshops) . The workshops were simplified into aluminum alloy processing and welding workshop and assembly workshop, with the addition of carbon fiber production and carbon fiber parts pre - assembly workshops for models that use carbon fiber products . It has the following advantages compared to traditional car factories : Obtained the national new energy passenger vehicle production qualification in 2016 from the National Development and Reform Commission. Low Production Line Investment: It removed the stamping and painting workshops, and significantly reduces the basic investment in factory lines and equipment. High Efficiency: The number of parts is greatly reduced and the production line is shortened. Production time is greatly increased by eliminating the painting and drying process. Reduced Pollution: The most polluting painting process has been eliminated. The factory is adjacent to Taihu Lake which has stringent environmental assessment requirements. High Energy Savings: The stamping and painting workshops which require the most electricity and heat were also eliminated.
