On 26 April 2017 (after trading hours), the Company entered into the Airbus Aircraft Acquisition Agreement with Airbus S.A.S. to purchase the Airbus Aircraft from Airbus S.A.S..

1. The Company, as the purchaser. The principal business activity of the Company is that of civil aviation.

2. The Airbus S.A.S., a company incorporated in Toulouse, as the vendor. The principal business activity of Airbus S.A.S. is that of aircraft manufacturing. To the best of the Directors' knowledge, information and belief having made all reasonable enquiry, each of Airbus S.A.S. and its ultimate beneficial owner is a third party independent of the Company and connected persons (as defined in the Listing Rules) of the Company, and is not a connected person of the Company.

According to the information provided by Airbus S.A.S., the catalogue price of each Airbus

A350-900 aircraft is priced about US$298.9 million. Such catalogue price includes price for airframe and engine.

The Airbus Aircraft Acquisition Agreement was negotiated and entered into with customary business and industry practice. The aggregate actual consideration for the Airbus Aircraft, which is payable in cash, and determined after an arm's length negotiation between the parties, is significantly lower than the catalogue price as provided by Airbus S.A.S. because of the substantial price concessions granted by Airbus S.A.S. in relation to the Airbus Aircraft. The Board (including the independent non-executive Directors) is of the view that there is no material impact of the price concessions obtained in the Acquisition on the operating costs of the Group.

In respect of the Acquisition, the Airbus Aircraft Acquisition Agreement contains confidentiality provisions restricting, among other things, disclosure of the consideration of the Acquisition. In addition, consistent with the customary practice of the local aviation industry, the consideration for the acquisition of the Airbus Aircraft is not customarily disclosed to the public. The Company has on separate occasions sought the consents of Airbus

S.A.S. to the Company's disclosure of certain information as required under Chapter 14 of the Listing Rules (including the relevant actual consideration involved) in the relevant announcements and circulars. Nonetheless, Airbus S.A.S. rejected the Company's request in this respect, and insisted preservation of the confidentiality carried with such information to the extent possible. Disclosure of the actual consideration will result in the loss of the significant price concessions and hence a significant negative impact on the Group's cost for the Acquisition and will therefore not be in the interest of the Company and its Shareholders

as a whole. The Company has made an application to the Stock Exchange for a waiver from strict compliance with the relevant provisions under the Listing Rules in respect of the disclosure of the actual consideration for the Airbus Aircraft, and the Stock Exchange has granted such waiver.

The Board is of the view that the extent of the price concessions granted to the Company in the Acquisition is comparable with the price concessions that the Group had obtained in the past. The Company also believes that there is no material difference between the effect of the price concessions obtained in the Acquisition and each of the previous purchase from Airbus

S.A.S. on the Group's operating costs taken as a whole.

The aggregate consideration for the Acquisition is payable by cash in United States dollars. The consideration will be partly payable by cash and partly by financing arrangements with banking institutions. The Airbus Aircraft will be delivered in stages to the Company during the period commencing from 2019 to 2022, in which 6 aircraft, 6 aircraft, 4 aircraft and 4 aircraft will be delivered in each year from 2019 to 2022, respectively. The total consideration will be paid to Airbus S.A.S. in instalments according to the respective delivery schedule for each of the relevant Airbus Aircraft from 2019 to 2022.

The Acquisition will be funded partly by internal resources of the Company and partly through commercial loans by commercial banks. Such commercial banks are not and will not be connected persons (as defined in the Listing Rules) of the Company. As of the date hereof, the Company has not entered into any agreement with any of these commercial banks for financing the Acquisition. The Company will follow the necessary legal procedures and will make the necessary disclosure in accordance with the Articles of Association and comply with the applicable Listing Rules when the Company enters into any agreement with any commercial bank for financing the Acquisition.

The Acquisition is subject to the following:

1. the approval of the relevant government authorities in the PRC; and

2. the Shareholders' approval,

pursuant to the Listing Rules, the Articles of Association and the relevant rules and regulations of the Shanghai Stock Exchange.

To the best of the knowledge, information and belief of the Directors, after having made all reasonable enquiries, no Shareholder or any of their respective associates have any material interest in the Airbus Aircraft Acquisition Agreement and the Acquisition, thus no Shareholder is required to abstain from voting in respect of the proposed resolution to approve the Acquisition.

The Directors (including the independent non-executive Directors) consider that the Acquisition is consistent with the development strategy and the aircraft fleet structure plan of the Group under the 13th Five-Year Plan; and the Acquisition will facilitate the internationalization of the Company, maintain and improve the Company's air capacity, thus maximizing the operational efficiency and enhancing the competitiveness of the Group. It is expected that the Acquisition will make the Company have a better performance on the cost and efficiency, so as to enhance the competitiveness of the Group. The Airbus Aircraft will increase the ATKs of the Group by 12.1%, when compared to the ATKs of the Group as at 31 December 2016, without taking into account the adjustment to be made by the Company according to market conditions and age of the aircraft fleet.

The Directors (including the independent non-executive Directors) consider that the Acquisition is in the ordinary and usual course of business of the Group, the terms of the Airbus Aircraft Acquisition Agreement are fair and reasonable, are on normal commercial terms and in the interests of the Company and its Shareholders as a whole.

The relevant percentage ratio for the Acquisition with regards to the consideration test under Rule 14.07 of the Listing Rules is above 25% and less than 100%.
