The Company proposed to pay the aforesaid dividends on 4 July 2018. For the H Shares, the dividends shall be paid to Shareholders whose names appear on the register of members of the Company on 5 June 2018.

In accordance with the "Enterprise Income Tax Law of the People's Republic of China" 《( 中華人民共和國企業所得稅法》) and the "Rules for the Implementation of the Enterprise Income Tax Law of the People's Republic of China" 《( 中華人民共和國企業所得稅法實施條例》), both implemented on 1 January 2008 and the "Notice of the State Administration of Taxation on Issues Relevant to the Withholding of

Enterprise Income Tax on Dividends Paid by PRC Enterprises to Offshore Non-resident Enterprise Holders of H Shares" (Guo Shui Han [2008] No. 897) 《( 關於中國居民企業向境外H股非居民企業股東派發股息代扣代繳企業所得稅有關問題的通知》(國稅函[2008]897號)) promulgated by the State Administration of Taxation on 6 November 2008, the Company is obliged to withhold and pay PRC enterprise income tax on behalf of non-resident enterprise shareholders at a tax rate of 10% from 2008 onwards when the Company distributes any dividends to non-resident enterprise shareholders whose names appear on the register of members of H Shares of the Company. As such, any H Shares of the Company which are not registered in the name(s) of individual(s) (which, for this purpose, includes Shares registered in the name of HKSCC Nominees Limited, other nominees, trustees, or other organisations or groups) shall be deemed to be H Shares held by non-resident enterprise shareholder(s), and the PRC enterprise income tax shall be withheld from any dividends payable thereon. Non-resident enterprise shareholders may wish to apply for a tax refund (if any) in accordance with the relevant requirements, such as tax agreements (arrangements), upon receipt of any dividends.

In accordance with the "Circular on Certain Issues Concerning the Policies of Individual Income Tax" (Cai Shui Zi [1994] No. 020) 《( 關於個人所得稅若干政策問題的通知》(財稅字 [1994] 020號)) promulgated by the Ministry of Finance and the State Administration of Taxation on 13 May 1994, overseas individuals are, as an interim measure, exempted from the PRC individual income tax for dividends or bonuses received from foreign-invested enterprises. As the Company is a foreign-invested enterprise, the Company will not withhold and pay the individual income tax on behalf of individual shareholders when the Company distributes the 2017 final dividends to individual shareholders whose names appear on the register of members of H Shares of the Company.

Pursuant to the Circular on Tax Policies Concerning the Pilot Programme of the Shanghai and Hong Kong Stock Market Trading Interconnection Mechanism (Cai Shui [2014] No. 81) 《( 關於滬港股票市場交易互聯互通機制試點有關稅收政策的通知》(財稅[2014]81號)) and the Circular on Tax Policies Concerning the Pilot Programme of the Shenzhen and Hong Kong Stock Connect (Cai Shui [2016] No.127) 《( 關於深港股票市場交易互聯互通機制試點有關稅收政策的通知》(財稅[2016]127號)), promulgated by the Ministry of Finance, the State Administration of Taxation and CSRC on 31 October 2014 and 5 November 2016 respectively:

IV. 2018-2019 AIRCRAFT FINANCE LEASE SERVICE FRAMEWORK AGREEMENT

Reference is made to the announcement dated 27 March 2018 in relation to the Aircraft Finance Lease Transactions under the 2018-2019 Aircraft Finance Lease Service Framework Agreement. As the Group and the CNACG Group intend to carry out aircraft finance lease business in the years of 2018 and 2019, the Company and CNACG entered into the 2018-2019 Aircraft Finance Lease Service Framework Agreement on 27 March 2018 in relation to the Aircraft Finance Lease Transactions.

1. 2018-2019 Aircraft Finance Lease Service Framework Agreement

27 March 2018

The Company and CNACG

Pursuant to the 2018-2019 Aircraft Finance Lease Service Framework Agreement, CNACG Group agreed to provide finance lease services to the Group in relation to Leased Aircraft. The Lessor(s) will be the subsidiary(ies) of CNACG which is/are qualified for providing aircraft finance lease services, and the Lessee(s) will be the Company or its subsidiaries.

The Leased Aircraft comprises part of the aircraft to be introduced by the Company in 2018 and 2019, subject to adjustment from time to time. The Company has signed aircraft purchase agreements with Airbus S.A.S. and Boeing Company in relation to the Leased Aircraft, which agreements have been negotiated and agreed independently and separately and has fulfilled the approval procedures of the Board and the Company's general meetings and announcement obligations in accordance with relevant laws and regulations (including the Hong Kong Listing Rules).

Rental Fee

The rental fee is the repayment of the principal amount for the Leased Aircraft and the interest under the Aircraft Finance Lease Transactions. The aggregate principal amount shall be not more than 100% of the consideration for the purchase of the Leased Aircraft. The applicable interest rate will be further determined and agreed by the Lessor and Lessee through requests for proposals issued by the Group or other procurement processes of the Group and shall satisfy the pricing policy as disclosed below.

The rental fee of which the principal portion is measured according to the equal- principal (equal instalment principal and corresponding interests incurred by the remaining principal) or average-principal-plus-interests (average instalment for all the principal and interests) standard, is payable monthly, quarterly or semi-annually in arrears, commencing on the Delivery Date of the Leased Aircraft and concluding on the date of the last payment for such Leased Aircraft. The frequency of rental fee payment and the calculation method of principal portion will be determined on a case-by-case basis taking into account the proposals submitted by CNACG Group and independent third parties and the cash position of the Lessee. The Lessor will provide the Lessee with full value added tax invoices in respect of the principal amount for the Leased Aircraft and the interest thereunder.

Arrangement Fee

The respective arrangement fee for the Leased Aircraft will be further determined and agreed by the Lessee(s) and Lessor(s) in line with the pricing policy as disclosed below. The arrangement fee shall be paid by the Lessee to the Lessor in one lump sum prior to the commencement of the respective Delivery Date.

The actual determination of the interest rate and the arrangement fee will be considered as a whole and governed by the pricing policy as disclosed below.

The comprehensive costs (including the relevant rental fee plus arrangement fee) provided by CNACG Group to the Group in its finance lease proposal(s) shall be not higher than those provided by at least three independent third parties who have received the Group's request for proposals or are shortlisted in the same procurement processes of the Group.

Buy-back

Upon the payment of the last instalment of rental fee by the Lessee(s) to the Lessor(s) for the relevant Leased Aircraft, the Lessee(s) is entitled to purchase the relevant Leased Aircraft back from the Lessor(s) at a nominal purchase price.

Implementation Agreements

To implement the Aircraft Finance Lease Transactions, separate Finance Lease Agreement(s) will be entered into between the Lessee(s) and the Lessor(s) in respect of the Leased Aircraft, the terms of which will in all material respects be consistent with the binding principles, guidelines, terms and conditions contained in the 2018-2019 Aircraft Finance Lease Service Framework Agreement.

The 2018-2019 Aircraft Finance Lease Service Framework Agreement is effective upon approval of the 2018-2019 Aircraft Finance Lease Service Framework Agreement and the transactions and the Maximum Transaction Amounts contemplated thereunder by the Independent Shareholders at the AGM. The term of the 2018-2019 Aircraft Finance Lease Service Framework Agreement shall commence from the date of approval by the Independent Shareholders at the AGM to 31 December 2019.

The lease period of the Leased Aircraft under the 2018-2019 Aircraft Finance Lease Service Framework Agreement will be agreed upon entering into the individual Finance Lease Agreements. Based on previous similar transactions, the lease period of the Leased Aircraft under the individual Finance Lease Agreement(s) would be 10 to 12 years.

2. Proposed Maximum Transaction Amounts of the Aircraft Finance Lease Transactions

As at the Latest Practicable Date, CNACG Group has not carried out any aircraft finance lease transaction with the Group.

The total fee payable under the Aircraft Finance Lease Transaction(s) is the sum of the rental fee, the arrangement fee and the buy-back fee, and the total rental fee payable under the Aircraft Finance Lease Transactions equals to the sum of the principal and the interest payable under each Finance Lease Agreement for the entire lease period for each of the Leased Aircraft. The buy-back fee payable will be at a nominal level which is negligible when calculating the Maximum Transaction Amounts (normally ranges from nil to RMB10).

In arriving the proposed Maximum Transaction Amounts, considering the lease period for each of the Leased Aircraft would be 10 to 12 years, the Company adopted the prevailing benchmark interest rate i.e. 4.9%, for RMB loan for over 5 years promulgated by the PBOC (the "PBOC Benchmark Rate") for the calculation of estimated interest of the Aircraft Finance Lease Transactions. When entering into the separate Finance Lease Agreement for each of the Leased Aircraft, the actual interest rate will be determined through requests for proposals or other procurement processes with reference to the PBOC Benchmark Rate. During the term of the Aircraft Finance Lease Transactions, if the PBOC Benchmark Rate is adjusted by the PBOC, the interest rate for the Aircraft Finance Lease Transactions shall be adjusted accordingly in the same direction. However, based on the previous proposals received by the Group from independent third parties, the interest rate for each of the Leased Aircraft usually would not be higher than the PBOC Benchmark Rate.

The Company adopted 1% of the principal amount of the Leased Aircraft to calculate the estimated arrangement fee with reference to prevailing market conditions.

Based on (i) the above-mentioned calculation basis of the interest payable and arrangement fee payable under the Aircraft Finance Lease Transactions; (ii) the aircraft scheduled to be introduced by the Company for the period from 1 June 2018 to 31 December 2018 and for the year 2019 according to confirmed orders; and (iii) the assumption that the maximum aggregate principal amount of the 

Aircraft Finance Lease Transaction(s) between the Company and CNACG Group for the period from 1 June 2018 to 31 December 2018 and for the financial year ending 31 December 2019 shall not exceed half of the aggregate consideration amount of the aircraft scheduled to be introduced during such period/financial year according to confirmed orders, it is estimated that, for the Aircraft Finance Lease Transactions to be entered into during the period from 1 June 2018 to 31 December 2018, the rental fee payable for the entire lease period will be approximately US$1,038.34 million and the arrangement fee payable will be approximately US$8.25 million; for the Aircraft Finance Lease Transactions to be entered into during the financial year ending 31 December 2019, the rental fee payable for the entire lease period will be approximately US$1,480.28 million and the arrangement fee payable will be approximately US$11.75 million. As such, the proposed Maximum Transaction Amounts under the Aircraft Finance Lease Transactions are set out below:

3. Reasons for and benefits of the Aircraft Finance Lease Transactions

Entering into the 2018-2019 Aircraft Finance Lease Service Framework Agreement will broaden the aircraft financing channels to satisfy the business development need of the Group. The aircraft finance lease would provide more flexibility for the financing channels in respect of the aircraft to be introduced by the Group and have less impact on the cash flow of the Group. The Company is of the view that it is beneficial for the Company to enter into the 2018-2019 Aircraft Finance Lease Service Framework Agreement with CNACG after considering other financing options.

Firstly, compared with traditional bank loans, finance lease transaction(s)' application process is generally more relaxed and offers a higher loan-to-value ratio. Also, finance lease transaction is able to avoid the potential dilution effect from equity financing. In addition, by utilizing the finance lease structure to introduce the Leased Aircraft, the Lessor(s) can provide value added tax invoices for the principal amount and interest payments under the Finance Lease Agreements to the Lessee(s), and therefore, the Lessee(s) can use it to deduct value added tax. The respective arrangement fee for each of the Leased Aircraft would also be lower than the deductible value added tax in respect of the interest payments, which can help to reduce the financing costs of the Lessee(s).

Calculated based on the proposed Maximum Transaction Amounts of the Aircraft Finance Lease Transactions for the period from 1 June 2018 to 31 December 2018 and for the financial year ending 31 December 2019 respectively, through adopting the finance lease arrangement provided by CNACG Group under the 2018-2019 Aircraft Finance Lease Service Framework Agreement, the estimated total savable financing costs for the Group as compared to adopting secured loans arrangements with equivalent interest rates provided by the market over the same period will be approximately US$22.96 million in 2018, and US$32.75 million in 2019.

Secondly, based on the fact that (i) CNACG Group has an management team with wealthy experiences and is in stable operation; (ii) CNACG Group possesses a fairly strong financing ability with comparatively favorable credit policies provided by numerous domestic and foreign banks; and (iii) the relevant subsidiaries of CNACG Group providing aircraft finance lease service were registered in Beijing Tianzhu Free Trade Zone and Tianjin Dongjiang Free Trade Port Zone, and can therefore enjoy preferential financial policies supported by local governmental agencies, CNACG Group possesses a fairly strong capital advantage, and can guarantee adequate funding sources, and has the qualification and ability to engage in large-scale aircraft finance lease transaction(s).

Thirdly, the relevant business team of CNACG Group possess extensive knowledge and experience in aviation finance industries and has well comprehension on the business needs of the Group, therefore the business communication between the Group and CNACG Group would be more smoothly, and it is easier to achieve a mutual understanding with the principle of maximizing both parties' benefits in the agreement negotiation stage.

4. Internal Control Measures

The Company adopted the following measures to ensure that the Aircraft Finance Lease Transactions with the CNACG Group will be conducted on normal commercial terms and in accordance with the terms of the 2018-2019 Aircraft Finance Lease Service Framework Agreement and the pricing policy of the Company:

• The Company's finance department will request for proposals from potential service providers in relation to aircraft finance lease. If any member of the CNACG Group has been selected as the service provider, the Company's finance department, legal department, asset management department (under which there is a division responsible for the management of connected transactions) and certain other relevant departments (if applicable) will review the proposed terms of the Aircraft Finance Lease Transaction(s) to ensure that the Aircraft Finance Lease Transaction(s) will be conducted (i) in the ordinary and usual course of business of the Group; (ii) on normal commercial terms or better; and (iii) according to the 2018-2019 Aircraft Finance Lease Service Framework Agreement on terms that are fair and reasonable and in the interests of the Company and the Shareholders as a whole. The reviewed final financing plan will be reported to the management of the Company for approval.

• The asset management department of the Company is responsible for overseeing the connected transactions of the Company. The asset management department will monitor and collect detailed information on the Aircraft Finance Lease Transactions on a regular basis, including but not limited to the implementation of pricing policies, payment arrangements and actual transaction amount under each Aircraft Finance Lease Transaction to ensure that the transactions are conducted in accordance with the 2018-2019 Aircraft Finance Lease Service Framework Agreement. In addition, the asset management department will be responsible for inspection and assessment of the balance of the Maximum Transaction Amounts for the Aircraft Finance Lease Transactions on a monthly basis. If it is expected that the relevant Maximum

Transaction Amount would be exceeded, the asset management department will report to the management of the Company and take appropriate measures in accordance with the relevant requirements of the Hong Kong Listing Rules.

• The Company's internal audit department is responsible for performing the annual evaluation procedure on the internal control procedures of the Group, including but not limited to the relevant information on the management of the continuing connected transactions. In addition, the internal audit department is responsible for compiling the annual internal control evaluation report and submitting the report to the Board for examination and approval.

• The Company's independent auditor and independent non-executive Directors will conduct annual review of the Aircraft Finance Lease Transactions.

Based on the above, the Directors (including the independent non-executive Directors) are of the view that the Company has implemented effective internal control and risk management measures, and such methods and procedures can ensure that the transactions contemplated under the 2018-2019 Aircraft Finance Lease Service Framework Agreement will be conducted on normal commercial terms and are in the interests of the Company and the Shareholders as a whole.

5. Parties and Connected Relationship of the Parties

The Company's principal business activity is air passenger, air cargo and airline-related services.

CNACG is an investment holding company whose principal businesses include airport ground support services, airline catering services, aircraft maintenance and repair services, aircraft related materials lease services, property investment, ticket and tourism services, logistics and finance lease and operating lease services conducted through its subsidiaries.

6. Hong Kong Listing Rules Implications

CNACG is a substantial shareholder of the Company and is therefore a connected person of the Company as defined under the Hong Kong Listing Rules. According to Rule 14.22 and Rule 14A.81 of the Hong Kong Listing Rules, the Aircraft Finance Lease Transactions shall be aggregated with the Previous Transaction. As the highest of the applicable Percentage Ratios is higher than 5.0% but less than 25%, the Aircraft Finance Lease Transactions constitute continuing connected transaction and discloseable transaction of the Company under the Hong Kong Listing Rules. Therefore, the Aircraft Finance Lease Transactions and the proposed Maximum Transaction Amounts are subject to: (i) the disclosure, annual review and Independent Shareholders' approval requirements under Chapter 14A of the Hong Kong Listing Rules; and (ii) the requirementsapplicable to discloseable transactions under Chapter 14 of the Hong Kong Listing Rules. 

The Independent Board Committee has been formed to advise the Independent Shareholders on the Aircraft Finance Lease Transactions and the proposed Maximum Transaction Amounts thereunder. Challenge Capital has been appointed as the independent financial adviser of the Company to advise the Independent Board Committee and the Independent Shareholders in this regard.

At the fifth meeting of the fifth session of the Board held on 27 March 2018, the Board approved the 2018-2019 Aircraft Finance Lease Service Framework Agreement, the Aircraft Finance Lease Transactions and the proposed Maximum Transaction Amounts thereunder. Mr. Cai Jianjiang and Mr. Song Zhiyong are considered to have a material interest in the 2018-2019 Aircraft Finance Lease Service Framework Agreement and therefore have abstained from voting in the relevant board resolution in respect of the 2018-2019 Aircraft Finance Lease Service Framework Agreement, the Aircraft Finance Lease Transactions and the proposed Maximum Transaction Amounts thereunder. Save as disclosed above, none of the Directors has a material interest in the 2018-2019 Aircraft Finance Lease Service Framework Agreement and hence no other Director is required to abstain from voting on the relevant board resolution.

7. Shanghai Listing Rules Implications

Pursuant to the Shanghai Listing Rules, CNACG is a related party of the Company as it is controlled by the controlling shareholder of the Company. Therefore, the 2018-2019 Aircraft Finance Lease Service Framework Agreement shall be approved or ratified by Independent Shareholders at the AGM.

To: The Independent Board Committee and the Independent Shareholders of Air China Limited

Dear Sirs,

DISCLOSEABLE TRANSACTION AND CONTINUING CONNECTED TRANSACTION:

2018-2019 AIRCRAFT FINANCE LEASE SERVICE FRAMEWORK AGREEMENT

INTRODUCTION

We refer to our engagement as the independent financial adviser to the Independent Board Committee and the Independent Shareholders in respect of the Aircraft Finance Lease Transactions under the 2018-2019 Aircraft Finance Lease Service Framework Agreement and the proposed Maximum Transaction Amounts thereunder, details of which are set out in the letter from the Board (the "Letter from the Board") contained in the circular of the Company to the Shareholders dated 4 April 2018 (the "Circular"), of which this letter forms part. Capitalised terms used in this letter shall have the same meanings as those defined in the Circular unless otherwise defined or the context requires otherwise.

On 27 March 2018, the Company and CNACG entered into the 2018-2019 Aircraft Finance Lease Service Framework Agreement, pursuant to which the CNACG Group agreed to provide finance lease services to the Group in relation to the Leased Aircraft for the period from 1 June 2018 to 31 December 2018 and the year ending 31 December 2019 (the "Relevant Periods") in accordance with the terms and conditions and the relevant implementation agreements contemplated thereunder.

CNACG is a substantial shareholder of the Company and is therefore a connected person of the Company as defined under the Hong Kong Listing Rules. According to Rule 14.22 and Rule 14A.81 of the Hong Kong Listing Rules, the Aircraft Finance Lease Transactions shall be aggregated with the Previous Transaction. As the highest of the applicable Percentage Ratios is higher than 5.0% but less than 25%, the Aircraft Finance Lease Transactions constitute continuing connected transaction and discloseable transaction of the Company under the Hong Kong Listing Rules. Therefore, the Aircraft Finance Lease Transactions and the proposed Maximum Transaction Amounts are subject to: (i) the disclosure, annual review and Independent Shareholders' approval requirements under Chapter 14A of the Hong Kong Listing Rules; and (ii) the requirements applicable to discloseable transactions under Chapter 14 of the Hong Kong Listing Rules.

The Independent Board Committee has been formed to advise the Independent Shareholders on the Aircraft Finance Lease Transactions and the proposed Maximum Transaction Amounts thereunder. We, Challenge Capital Management Limited, have been appointed as the independent financial adviser of the Company to advise the Independent Board Committee and the Independent Shareholders in this regard.

We are independent from and not connected with the Company, CNACG, or any of their respective associates. Accordingly, we are considered eligible to give independent advice on the Aircraft Finance Lease Transactions. Apart from normal advisory fees payable to us for our services rendered to the Company in connection with this appointment, no arrangement exists whereby we shall receive any other fees or benefits from the Company, CNACG, or any of their respective associates.

PRINCIPAL FACTORS AND REASONS CONSIDERED

In formulating our opinion in respect of the Aircraft Finance Lease Transactions, we have considered the following principal factors and reasons:

1. Information of the Group and CNACG

The Company's principal activity is air passenger, air cargo and airline-related services. As stated in the interim report of the Company for the six months ended 30 June 2017 (the "2017 Interim Report"), the Company is the only Chinese civil aviation enterprise listed in "The World's 500 Most Influential Brands". It is the only national flag carrier of China and is a member of Star Alliance, the world's largest airline alliance. With Star Alliance, the network of the Company covered 1,307 destinations in 191 countries as at 30 June 2017.

As of 30 June 2017, the Group had a total of 628 aircraft, of which 176 were under finance leases, 204 were under operating leases, and 248 were self-owned, and maintained an average fleet age of 6.53 years (excluding aircraft under wet leases). As further disclosed in the 2017 Interim Report, the Group planned to introduce a total of 49 and 61 new aircraft in 2018 and 2019 respectively.

Set out below is a summary of the audited consolidated financial position of the Group as at 31 December 2016 and 2017, which was extracted from the annual results announcement of the Company for the year ended 31 December 2017 dated 27 March 2018:

The total assets of the Group increased by approximately 5.2% to approximately RMB235,645 million as at 31 December 2017 from approximately RMB224,051 million as at 31 December 2016. The total liabilities of the Group decreased from approximately RMB147,655 million as at 31 December 2016 to approximately RMB140,786 million as at 31 December 2017, representing a decrease of approximately 4.7%. The Group's gearing ratio (measured as total liabilities divided by total assets) was approximately 65.9% and 59.7% as at 31 December 2016 and 2017 respectively. The net assets of the Group amounted to approximately RMB94,859 million as at 31 December 2017, representing an increase of approximately 24.2% from approximately RMB76,396 million as at 31 December 2016.

As at 31 December 2017, total interest-bearing bank loans and other borrowings of the Group was approximately RMB50,763 million while total obligations under finance leases of the Group was approximately RMB44,036 million. The Group's cash and cash equivalents was approximately RMB5,563 million as at 31 December 2017.

CNACG is an investment holding company whose principal businesses include airport ground support services, airline catering services, aircraft maintenance and repair services, aircraft related materials lease services, property investment, ticket and tourism services, logistics and finance lease and operating lease services conducted through its subsidiaries.

2. Reasons for and benefits of the Aircraft Finance Lease Transactions

As stated in the Letter from the Board, by utilising the finance lease structure to introduce the Leased Aircraft, the Lessor(s) can provide value added tax invoices for the principal amount and interest payments under the Finance Lease Agreements to the Lessee(s), and therefore, the Lessee(s) can use such invoices to deduct value added tax. The respective arrangement fee for each of the Leased Aircraft would also be lower than the deductible value added tax in respect of the interest payments, which can help to reduce the financing costs of the Lessee(s). Calculated based on the proposed Maximum Transaction Amounts for the period from 1 June 2018 to 31 December 2018 and for the year ending 31 December 2019 respectively, through adopting the finance lease arrangement provided by the CNACG Group under the 2018-2019 Aircraft Finance Lease Service Framework Agreement, the estimated total savable financing costs for the Group as compared to adopting secured loan arrangements with equivalent interest rates provided by the market over the same period will be approximately US$22.96 million in 2018 and US$32.75 million in 2019.

We are advised that the Company entered into the 2018-2019 Aircraft Finance Lease Service Framework Agreement with a view to utilise such finance lease structure to enjoy potential cost savings while executing the aircraft introduction plan of the Group from 2018 to 2019.

The Company's principal activity is air passenger, air cargo and airline-related services. As disclosed in the 2017 Interim Report, the Group planned to introduce a total of 49 and 61 new aircraft in 2018 and 2019 respectively. We have discussed with the management of the Company and were given to understand that, the availability of financing channels is vital for the Group to facilitate its expansion plan.

According to "Current Aircraft Finance Market Outlook 2018" published by Boeing Capital Corporation in December 2017, the overall aircraft finance market is expected to continue to increase in 2018. According to "Guidance Material and Best Practices for Aircraft Leases (2th Edition)" published by the International Air Transportation Association in May 2015, an aircraft lease provides the airline with increased flexibility in fleet expansion. We noted from the previous annual reports of the Company and the 2017 Interim Report that, around 60% of the then fleet of the Group were held under finance leases and operating leases as at 31 December 2015, 31 December 2016 and 30 June 2017 respectively.

We further understand from the Company that, in respect of the aircraft to be introduced by the Group, the Company has been exploring alternative financing options such as bank borrowings and equity financing. Taking into account various factors including the generally less stringent application process and higher loan-to-value ratio offered by finance leasing as compared with traditional bank loans, and the potential dilution effect from equity financing, the Directors are of the view that it is beneficial for the Group to broaden its financing options by entering into the 2018-2019 Aircraft Finance Lease Service Framework Agreement.

In addition, the entering into the 2018-2019 Aircraft Finance Lease Service Framework Agreement provides an additional option to the Group to conduct its aircraft finance leasing business on terms no less favourable than those of independent third parties, which can in turn help to enhance the bargaining power of the Group in fund sourcing and hence the overall competitiveness of the Group.

In view of the above, we consider that the entering into of the 2018-2019 Aircraft Finance Lease Service Framework Agreement will help the Group to broaden its financing channels and provide additional flexibility to the Group to satisfy its need for introducing new aircraft in an organised and cost-efficient manner.

CNACG is a wholly-owned subsidiary of CNAHC, which is a state-owned enterprise under the supervision of the State Council and one of the three major air transportation groups in the PRC. Leveraging on the solid capital strength and the extensive network of CNAHC, it is believed that the CNACG Group can secure sufficient sources of funding to conduct aircraft finance lease transactions with the Group. Since the Company and CNACG are under common control of CNAHC, it is expected that smooth communication and cooperation between the two parties can help to maximise their mutual benefits. We were also given to understand that the business team responsible for conducting aircraft finance lease transactions of the CNACG Group possess extensive knowledge and experience in aviation finance industries. Having reviewed the profiles of the relevant business team members and taking into account the background of the CNACG Group and the Lessor(s) being qualified for providing aircraft finance lease services, we agreed with the Directors that the CNACG Group possesses the qualification and capability in engaging in large-scale aircraft finance lease transactions.

Furthermore, we noted that the Company and CNACG have previously entered into a framework agreement on 30 August 2016, details of which are set out in the announcement of the Company dated 30 August 2016. Pursuant to such framework agreement, the CNACG Group agreed to provide ground support services, aircraft repair and maintenance services, administrative management services, as well as finance lease services of aircraft simulators and new aircraft engines and operating lease services of back-up engines and ramp equipment to the Group. It is believed that the entering into of the 2018-2019 Aircraft Finance Lease Service Framework Agreement would allow the Group to receive more comprehensive finance lease services from the CNACG Group, which is favourable to the business development of the Group.

Based on the above, we are of the view that the entering into of the 2018-2019 Aircraft Finance Lease Service Framework Agreement is in the ordinary and usual course of business of the Group, and is in the interests of the Company and the Shareholders as a whole.

3. Principal terms of the 2018-2019 Aircraft Finance Lease Service Framework Agreement Date

The lease period of the Leased Aircraft under the 2018-2019 Aircraft Finance Lease Service Framework Agreement will be agreed upon entering into the individual Finance Lease Agreements. Based on previous similar transactions, the lease period of the Leased Aircraft under the individual Finance Lease Agreement(s) would be 10 to 12 years.

Please refer to the sub-section headed "1. 2018-2019 Aircraft Finance Lease Service Framework Agreement" in the section headed "IV. 2018-2019 Aircraft Finance Lease Service Framework Agreement" in the Letter from the Board for the details of the terms of the 2018-2019 Aircraft Finance Lease Service Framework Agreement.

To assess the fairness and reasonableness of the terms of the Aircraft Finance Lease Transactions, we have obtained and reviewed the 2018-2019 Aircraft Finance Lease Service Framework Agreement and further discussed with the Company in relation to the pricing policy as stated above. We understand that the Group will obtain and review finance lease proposals submitted by at least three independent third parties through requests for proposals or other procurement processes and evaluate whether the comprehensive costs

(including the relevant rental fee plus arrangement fee) provided by the CNACG Group are fair and reasonable and no less favourable to the Group than those offered by independent third parties before conducting the Aircraft Finance Lease Transactions with the Lessor(s). We also noted the 2018-2019 Aircraft Finance Lease Service Framework Agreement stipulates that the separate Finance Lease Agreement(s) to be entered into between the Lessee(s) and the Lessor(s) in respect of the Leased Aircraft shall in all material respects be consistent with the binding principles, guidelines, terms and conditions contained in the 2018-2019 Aircraft Finance Lease Service Framework Agreement.

Additionally, in order to ensure that the Aircraft Finance Lease Transactions will be conducted on normal commercial terms and in accordance with the terms of the 2018-2019 Aircraft Finance Lease Service Framework Agreement, the Company has adopted internal control and risk management measures as the following:

• The Company's finance department will request for proposals from potential service providers in relation to aircraft finance lease. If any member of the CNACG Group has been selected as the service provider, the Company's finance department, legal department, asset management department (under which there is a division responsible for the management of connected transactions) and certain other relevant departments (if applicable) will review the proposed terms of the Aircraft Finance Lease Transaction(s) to ensure that the Aircraft Finance Lease Transaction(s) will be conducted (i) in the ordinary and usual course of business of the Group;

(ii) on normal commercial terms or better; and (iii) according to the 2018-2019 Aircraft Finance Lease Service Framework Agreement on terms that are fair and reasonable and in the interests of the Company and the Shareholders as a whole. The reviewed final financing plan will be reported to the management of the Company for approval.

• The asset management department of the Company is responsible for overseeing the connected transactions of the Company. The asset management department will monitor and collect detailed information on the Aircraft Finance Lease Transactions on a regular basis, including but not limited to the implementation of pricing policies, payment arrangements and actual transaction amount under each Aircraft Finance Lease Transaction to ensure that the transactions are conducted in accordance with the 2018-2019 Aircraft Finance Lease Service Framework Agreement. In addition, the asset management department will be responsible for inspection and assessment of the balance of the Maximum Transaction Amounts for the Aircraft Finance Lease Transactions on a monthly basis. If it is expected that the relevant Maximum Transaction Amount would be exceeded, the asset management department will report to the management of the Company and take appropriate measures in accordance with the relevant requirements of the Hong Kong Listing Rules.

• The Company's internal audit department is responsible for performing the annual evaluation procedure on the internal control procedures of the Group, including but not limited to the relevant information on the management of the continuing connected transactions. In addition, the internal audit department is responsible for compiling the annual internal control evaluation report and submitting the report to the Board for examination and approval.

• The Company's independent auditor and independent non-executive Directors will conduct annual review of the Aircraft Finance Lease Transactions.

We noted from the above that the Company has adopted a set of internal control measures to assign specific responsibilities to various designated departments of the Company in performing regular review and cross-checking on the terms of the Aircraft Finance Lease Transactions in order to make sure that the Aircraft Finance Lease Transactions will be conducted in accordance with the terms of the 2018-2019 Aircraft Finance Lease Service Framework Agreement. We also consider that the requirement to obtain finance lease proposals from at least three independent third parties would allow the Group to obtain the then prevailing market terms of aircraft finance lease transactions in comparing the terms offered by the CNACG Group.

Having considered the above, we concur with the view of the Directors that the internal control and risk management measures of the Company can help to ensure that the Aircraft Finance Lease Transactions will be conducted in accordance with the terms of the 2018-2019 Aircraft Finance Lease Service Framework Agreement and that the pricing policy thereunder will enable the Aircraft Finance Lease Transactions to be conducted on terms no less favourable to the Group than those offered by independent third parties.

As such, we are of the view that that terms of the 2018-2019 Aircraft Finance Lease Service Framework Agreement are on normal commercial terms and are fair and reasonable so far as the Independent Shareholders are concerned.

4. Proposed Maximum Transaction Amounts

The Company determines the proposed Maximum Transaction Amount for each of the Relevant Periods based on (i) the calculation basis of the interest payable and arrangement fee payable under the Aircraft Finance Lease Transactions as discussed below; (ii) the aircraft scheduled to be introduced by the Company for each of the Relevant Periods according to confirmed orders, and (iii) the assumption that the maximum aggregate principal amount of the Aircraft Finance Lease Transactions for each of the Relevant Periods shall not exceed half of the aggregate consideration amount of the aircraft scheduled to be introduced during the same period according to confirmed orders. It is estimated that, for the Aircraft Finance Lease Transactions to be entered into during the period from 1 June 2018 to 31 December 2018, the rental fee payable for the entire lease period will be approximately US$1,038.34 million and the arrangement fee payable will be approximately US$8.25 million; for the Aircraft Finance Lease Transactions to be entered into during the year ending 31 December 2019, the rental fee payable for the entire lease period will be approximately US$1,480.28 million and the arrangement fee payable will be approximately US$11.75 million.

Based on the above, the proposed Maximum Transaction Amounts are set out as below:

Units: US$ in millions

The proposed Maximum Transaction Amount for each of the Relevant Periods represents the maximum aggregate amount payable by the Lessee(s) to the Lessor(s) throughout the lease period and is the sum of the rental fee payable and the arrangement fee payable as estimated by the Group. In particular, the rental fee payable under the Aircraft Finance Lease Transactions equals to the sum of the principal and the interest payable in respect of the Leased Aircraft. As stated in the Letter from the Board, the buy-back fee payable will be at a nominal level (normally ranges from nil to RMB10) which is negligible when calculating the proposed Maximum Transaction Amounts.

In order to assess the fairness and reasonableness of the proposed Maximum Transaction Amounts, we have obtained from the Company a computation which includes the relevant aircraft scheduled to be introduced by the Company during each of the Relevant Periods according to confirmed orders (the "Relevant Aircraft"), the expected purchase price upon delivery, together with the calculation of the rental fee (including the principal and interest payable) and arrangement fee with respect to the Leased Aircraft. As the maximum aggregate principal amount of the Aircraft Finance Lease Transactions for each of the Relevant Periods shall not exceed half of the aggregate consideration amount of the Relevant Aircraft scheduled to be introduced during the same period, we noted from the computation that the Company adopted half of the total expected purchase price upon delivery of the Relevant Aircraft scheduled to be introduced during each of the Relevant Periods as the relevant principal amount of the Aircraft Finance Lease Transactions, which also represents the principal portion of the rental fee with respect to the Leased Aircraft. The interest payable is derived by applying an annual interest rate to the relevant principal amount throughout the expected lease period of 10 years. The arrangement fee, which is a one-off fee payable prior to the delivery of the Relevant Aircraft, is calculated based on a percentage of the relevant principal amount.

We have performed a search of aircraft finance lease transactions announced by major airlines or aircraft leasing companies that are listed on the Stock Exchange since October 2017 on a best effort basis, and have not identified any such transaction which has disclosed the relevant information including interest rate, arrangement fee and buy-back fee. However, we noted that China Southern Airlines Company Limited (stock code: 1055) published a circular to its shareholders dated 26 October 2017 in relation to, among others, its aircraft finance lease continuing connected transactions, and has adopted the PBOC benchmark interest rate for RMB loan with term over 5 years as the interest rate, a 1% rate as the handling fee and a nominal purchase price as the buy-back fee in arriving the relevant proposed cap, which are in line with the relevant parameters adopted by the Company in determining the proposed Maximum Transaction Amounts. In addition, we have expanded our search scope to include finance lease transactions announced by listed companies on the Stock Exchange since October 2017 based on the following selection criteria: (i) the finance lease transactions are conducted in the PRC; and (ii) the underlying assets are used in the principal businesses of the listed companies. To the best of our knowledge and as far as we are aware of, 19 reference cases were identified based on the aforesaid criteria (the "Reference Cases"), the details of which are set out in the table below. While the underlying assets of the Reference Cases are not aircraft, we consider that the Reference Cases can provide a general reference for the relevant parameters such as interest rate, arrangement fee and buy-back fee of recent finance lease transactions in the PRC.

Notes:

(1) The PBOC rate refers to the benchmark interest rate for RMB loans as promulgated by the PBOC from time to time for the corresponding period of the respective lease term.

(2) No arrangement fee is disclosed in the relevant announcement and a handling fee/service fee/commission and notarial fee/administration fee is payable by the lessee(s). Such fee has been adopted as arrangement fee in terms of percentage of principal amount in the above analysis.

(3) Interest rate is not disclosed in the relevant announcement. However, it is disclosed that the interest rate is calculated with reference to the benchmark interest rate for RMB 1-5 years loans according to the PBOC from time to time.

(4) Interest rate is not disclosed in the relevant announcement. However, it is disclosed that the interest rate is subject to adjustment with reference to the benchmark interest rate for RMB loans with the same maturity as the lease period as promulgated by the PBOC from time to time.

(5) It is disclosed in the relevant announcement that the interest rate is calculated on the basis of the 5-year benchmark loan interest rate published by the PBOC.

(6) It is disclosed in the relevant announcement that the interest rate shall be adjusted with reference to the benchmark interest rate for RMB loans as promulgated by the PBOC from time to time.

(7) Interest rate is not disclosed in the relevant announcement. However, it is disclosed that the interest rate shall be adjusted with reference to the benchmark interest rate for RMB loans with the same maturity as the lease period as promulgated by the PBOC from time to time plus a premium.

(8) It is disclosed in the relevant announcement that the interest rate is determined at a 20% premium over the three-year benchmark lending rate promulgated by the PBOC, and to be adjusted and calculated according to such benchmark lending rate during the lease period.

(9) It is disclosed in the relevant announcement that the interest rate is subject to adjustments during the lease period according to the then prevailing benchmark interest rate for loans for the same period.

(10) Interest rate is not disclosed in the relevant announcement. However, it is disclosed that the interest rate is subject to the changes of the benchmark interest rates in China.

We have reviewed the Company's previously published announcements in relation to the acquisition of the Relevant Aircraft (the "Previous Announcements") and noted that the expected delivery timeline for each of the Relevant Aircraft set out on the computation is within the delivery period as set out on the Previous Announcements and the expected purchase price upon delivery is within the basic price level as disclosed on the Previous Announcements. We have discussed with the management of the Company and were given to understand that the difference between the basic price and the expected purchase price upon delivery in respect of each of the Relevant Aircraft mainly relates to the price concessions granted by the aircraft manufacturer(s) to the Company which are consistent with customary business and industry practise and the Company's past transactions with the aircraft manufacturer(s).

With respect to the interest payable, we noted that the prevailing benchmark interest rate for RMB loan with term over 5 years as promulgated by the PBOC is applied for the purpose of the computation. In this regard, we have obtained and reviewed five sample aircraft finance lease proposals submitted by independent third parties to the Group in the past two years (the "Sample Finance Lease Proposals") and noted that the quoted interest rates were also determined with reference to such benchmark interest rate. We also noted from the Reference Cases that the applicable interest rate for finance lease arrangements conducted in the PRC are commonly determined with reference to the benchmark interest rate for RMB loans as promulgated by the PBOC from time to time.

With respect to the lease period, we understand from the management of the Company that the estimated useful life of the aircraft is often considered in determining the lease period for aircraft finance lease arrangement and that such period normally does not exceed the estimated useful life of the leased aircraft. According to the Letter from the Board, the Company expected that the lease period of the Leased Aircraft under the individual Finance Lease Agreement(s) would be 10 to 12 years, and we noted from the computation that a lease period of 10 years is applied. As disclosed in the annual report of the Company for the year ended 31 December 2016 and as confirmed with the Company, under the Company's accounting policy for depreciation of property, plant and equipment, the estimated useful life of its aircraft ranges from 15 to 30 years. We also noted from the Sample Finance Lease Proposals that the lease periods offered by the independent third parties were 10 years. Furthermore, we noted from the finance lease transactions in relation to new aircraft introduction previously announced by other major Chinese airlines that are listed on the Stock Exchange (namely, China Eastern Airlines Corporation Limited (stock code: 670) and China Southern Airlines Company Limited (stock code: 1055)) that the lease period of such transactions ranged from 10 to 12 years. Based on the above, we are of the view that the expected lease period of 10 to 12 years of the Leased Aircraft as adopted by the Company is in line with normal business practice in the Chinese aviation industry.

With respect to the arrangement fee computation, we noted that a 1% rate is adopted. We noted from the Sample Finance Lease Proposals that the one-off arrangement fees quoted by the independent third party lessors were based on a percentage ranging from nil to 0.5% of the principal amount of the finance leases. We also noted from the Reference Cases that, for those cases which have disclosed the arrangement fee, such fee ranged from approximately 0.6% to 4.5% of the principal amount of the finance leases.

As for the buy-back fee, the Lessee(s) is entitled to purchase the Leased Aircraft back from the Lessor(s) at a nominal purchase price upon the payment of the last instalment of the rental fee. We noted that the buy-back fee is not included in the computation as the Company considers that it will be at a nominal level which is negligible when calculating the proposed Maximum Transaction Amounts. In this regard, we noted from the Reference Cases that, for those which have disclosed the buy-back fee, it was common for the buy-back fee in respect of finance lease arrangement to be charged at a nominal price ranging from RMB1 to RMB10,000. We also noted from the Sample Finance Lease Proposals that the buy- back fee quoted by the independent third party lessors ranged from nil to RMB10.

Having considered the above, we are of the view that the proposed Maximum Transaction Amounts are fair and reasonable so far as the Independent Shareholders are concerned, and are in the interests of the Company and the Shareholders as a whole.

RECOMMENDATIONS

Having considered the above principal factors and reasons, we are of the opinion that the Aircraft Finance Lease Transactions are in the ordinary and usual course of business of the Company and on normal commercial terms, and the terms of the 2018-2019 Aircraft Finance Lease Service Framework Agreement (including the proposed Maximum Transaction Amounts) are fair and reasonable so far as the Independent Shareholders are concerned and in the interests of the Company and the Shareholders as a whole. Accordingly, we recommend the Independent Shareholders, and advise the Independent Board Committee to recommend the Independent Shareholders, to vote in favour of the relevant resolution to be proposed at the AGM to approve the Aircraft Finance Lease Transactions under the 2018-2019 Aircraft Finance Lease Service Framework Agreement and the proposed Maximum Transaction Amounts thereunder.
