APPENDIX A

GENERAL TERMS AND CONDITIONS

Capitalized terms used herein and not otherwise defined in this Appendix shall have the meanings assigned thereto in the Agreement or as defined in the Sector Understanding on Export Credit for Civil Aircraft as entered into force on February 1, 2011 as may be further amended from time to time by the OECD.

Unless otherwise stated or decided by the Export Credit Agencies in their sole discretion, the following general terms and conditions shall apply to the Facility:

1 Purpose and Amount

The amount of the Facility shall be up to a maximum of eighty-five percent (85%) if the Buyer is in risk category 2 or below, up to a maximum of eighty percent (80%) if the Buyer is in risk category 1, or such lesser percentage as may be selected by the Buyer or imposed by the Export Credit Agencies, in each case of the Net Aircraft Price of the Relevant Aircraft.

The list of these risk categories is defined by experts nominated by the members of the OECD. Such list is confidential to the OECD members and is updated on an on-going basis. The risk classifications reflect the senior unsecured credit rating of the Buyer (see Table 1 in appendix).

The Net Aircraft Price shall be equal to the Final Price (as defined in the Agreement) of the Relevant Aircraft including the engines/propulsion systems (the “Engines”) installed on such Relevant Aircraft after taking into account all price discounts and other cash credits, less all other credits or concessions of any kind of the Seller and/or the selected engine/propulsion system manufacturer (the “Engine Manufacturer”) related or fairly allocable thereto.

Subject to the Export Credit Agencies’ prior approval, the Net Aircraft Price may include Buyer Furnished Equipment installed on the Relevant Aircraft in an amount agreed by the Export Credit Agencies.

As requested by the Export Credit Agencies, the Buyer shall provide the Seller with a declaration signed by the selected Engine Manufacturer, indicating the total amount of the credit memoranda made available to the Buyer with respect to the Engines installed on the relevant Aircraft.

2 Participation and Currencies

The level of participation in the Facility from the British, French and German Export Credit Agency shall depend on the aircraft type and the Engine selected by the Buyer.

The Buyer may select from the following eligible currencies the currency in which he wishes to denominate the Facility.

The currencies that are eligible for such Facility are Euros (“EUR”), Japanese Yen (“JPY”), UK Sterling Pounds (“GBP”), US Dollars (“USD”) and other fully convertible currencies for which there are market references.

- Letter Agreement No 2 -Page 5/10

LETTER AGREEMENT No. 2 TO AMENDMENT No. 8 and AMENDMENT No. 9

3 Drawdowns and Payment to the Seller

The Facility relating to the Relevant Aircraft shall be drawn down upon delivery of such Relevant Aircraft and shall be disbursed directly to the Seller upon satisfactory presentation, inter alia, of the following documents:

(i) an aircraft invoice issued by the Seller and

(ii) the Certificate of Acceptance

in each case in respect of the Relevant Aircraft duly signed by a representative of the Buyer

Notwithstanding any decision by the Buyer to select a currency or currencies other than USD, the Seller shall receive the Final Price in USD at delivery of the Relevant Aircraft.

4 Term and Repayment of the Facility

The term of the Facility (the “Term”) shall not exceed twelve (12) years.

Unless otherwise decided by the Export Credit Agencies in their sole discretion, the British, French and German portions shall be repayable in a series of annuity style equal payments of rent in the case of a Lease Facility (as defined below) to amortise the Facility in respect of the Relevant Aircraft to zero over the Term.

There shall be no extension of the repayment Term by way of sharing of rights in the security on a pari passu basis with commercial lenders for the officially supported export credit.

The period between each payment shall be no greater than three (3) months and the first payment shall become payable no later than three (3) months after delivery of the Relevant Aircraft.

5 Interest

Interest on the Facility shall be payable in arrears on the unpaid balance of principal, on the same date as and together with the instalments of principal except when lease payments in advance are requested as a Risk Mitigant (as defined below) and in the currency(ies) in which the Facility is denominated.

The rate of interest shall be negotiated directly with the Banks and shall be either a floating rate or a fixed rate. Subject to the Export Credit Agencies’ prior approval, the Facility may also include an option to switch from a floating rate to a fixed rate on terms and conditions to be defined.

6 Expenses and Taxes

The Buyer shall be responsible for all legal expenses, professional fees as well as taxes and other costs arising out of or in connection with the application for, the provision and administration of the Facility, including the Export Credit Agencies’ travel expenses related to the Buyer’s presentation and/or to the negotiation of the Facility, whether or not the Facility is actually used. All corporate and governmental approvals necessary for the performance of the Buyer’s obligations under the Facility shall be obtained by the Buyer so that the payment of all amounts due to the Banks shall be satisfied without delay, such payments to be without deduction on

A320FAM PA – VOI – AMDT 8 and 9 LA02 – Ref. D11032737 - December 2011

- Letter Agreement No 2 -Page 6/10

LETTER AGREEMENT No. 2 TO AMENDMENT No. 8 and AMENDMENT No. 9

account of any existing or future withholding taxes, charges, levies or other duties whatsoever. If however any such deduction has to be made, the Buyer shall compensate the Banks for such deduction and shall obtain all necessary approvals for this purpose so that the Banks receive the same net amount as they would have received had no such deduction been made.

7 Security and Form of the Facility

As security for the repayment of the Facility, the Buyer shall provide a full security package satisfactory to the Export Credit Agencies and the Banks.

The standard form of the Facility shall be a finance lease (the “Lease Facility”). Under the Lease Facility, the Banks shall create a special purpose vehicle (“SPV”) which (i) shall receive title to the Relevant Aircraft pursuant to an assignment to the SPV of the relevant rights and obligations of the Buyer under the Agreement, and (ii) shall lease such Relevant Aircraft to the Buyer for the Term of the Facility.

Upon expiry of the Lease Facility and provided that no event of default has occurred or is continuing and provided no cross default and no cross collateralization have been called by the ECAs, the Buyer shall be entitled to purchase the Relevant Aircraft for the greater of the amount of 1$ and the outstanding amount due under the Lease Facility. Upon the exercise by the Buyer of the purchase option and payment of all amounts due under the Lease Facility, title to the Relevant Aircraft shall be transferred from the SPV to the Buyer simultaneously.

8 Premium

The premium to be paid up-front by the Buyer to the Export Credit Agencies in respect of the Facility shall be decided by the Export Credit Agencies. It shall be no less than the Minimum Premium Rates, or if the Buyer is based in a State where the Cape Town Convention applies, the Minimum Premium Rates with a reduction of 10% [Table 1 sets out the current Minimum Premium Rates with and without the Cape Town discount.]

The Minimum Premium Rate incorporates (i) a Risk Based Rate which is reset every year to reflect Moody’s annual Loss Given Default over a four-year period, and (ii) a Market Reflective Surcharge which is adjusted every quarter.

The calculation of the Risk Based Rate depends on the risk classification of the Buyer. The premium payable is expressed as a percentage of the amount of the Facility granted by the Export Credit Agencies.

The Buyer may benefit from a 10% Premium reduction if the Buyer is based in a jurisdiction that has ratified the Cape Town Convention with the qualifying declarations as defined by the OECD and has incorporated the Treaty in its set of domestic laws.

9 Main Terms of Financing

The Export Credit Agencies may, upon request of the Buyer, agree to provide financing support at or above the Minimum Premium Rate if all the conditions below are fulfilled to the satisfaction of the Export Credit Agencies and the Banks:

(i) an asset-backed transaction

(ii) a first priority security interest in the Relevant Aircraft

(iii) no more than 85% advance rate of the Net Aircraft Price (except if the Buyer is in risk category 1 in which case it is no more than 80%)

(iv) no less frequently than quarterly mortgage-style payments

(v) cross default and cross collateralization of all aircraft and engines owned legally and beneficially by the same parties under the proposed financing.

4	B+	2	1	1
5	B	2	1	1
6	B-	3	2	1
7	CCC	4	3	1
8	CC to C	4	3	1

Risk Mitigants shall be defined as follows:

“A” Risk Mitigants

I. each 5% reduction from the 85% Net Aircraft Price advance rate, (e.g. 70% advance rate where three A Risk Mitigants are required);

II. a straight line amortisation

III. a repayment term, which does not exceed ten years

“B” Risk Mitigants

I- Security Deposit in an amount equal to one quarterly instalment of principal and interest
