This free writing prospectus reflects the following amendments that were made in Amendment No. 3. All references to page numbers are to page numbers in Amendment No. 3.

(1) Amend the second paragraph on page 60 as follows:

Furthermore, if you are unsuccessful in such arbitration, you may be responsible for the fees of the arbitrator and other costs incurred by the parties in connection with such arbitration pursuant to the deposit agreement.

(2) Amend the second paragraph on page 127 as follows:

Pursuant to the framework agreement, the parties have agreed to cooperate in the following areas: (i) building systematic solutions for electric cars, charging piles and grid network by leveraging each party’s own resources and standardizing electric vehicle charging and battery swap technology, (ii) application of smart vehicle connectivity technology to practice, (iii) innovation in electric vehicle charging and battery swap technology, (iv) the construction and operation of electric vehicle charging and battery swap infrastructure, and (v) the sales, leasing and insurance of electric vehicles. While this framework agreement sets forth certain long-term strategic cooperation principles for cooperation between the State Grid Cooperation of China and us, the actual implementation of such principles would likely require the parties to enter into supplemental agreements covering specific areas of cooperation.
