RECITALS

Pursuant to Lease Agreement (CAC [     ]), dated as of December 16, 2009 (as previously amended and supplemented, the “Lease Agreement”), between Existing Lessor, as lessor, and Lessee, as lessee, in respect of one Airbus A330-200 aircraft with manufacturer’s CAC [   ] and manufacturer’s serial number [     ] (the “Aircraft”), Existing Lessor agreed to lease and Lessee agreed to take on lease the Aircraft upon the terms and conditions set out therein.

Existing Lessor and New Lessor desire that Existing Lessor transfer to New Lessor by novation the Lease Agreement, and Lessee is willing to agree to such novation, in each case upon the terms and conditions contained herein.

AGREEMENT

In consideration of the foregoing premise, and for other good and valuable consideration the adequacy and receipt of which are hereby acknowledged, the parties hereto agree as follows:

1. DEFINITIONS AND CONSTRUCTION

The capitalized terms used in this Agreement shall have the respective meanings ascribed thereto below:

“Novated Lease” means the Lease Agreement as novated and amended by this Agreement.

Capitalized terms used, but not defined, in this Agreement shall have the respective meanings assigned to them in the Lease Agreement.

The provisions of Part II of Schedule 1 to the Lease Agreement shall apply to this Agreement as if set out herein in full and as if references therein to “this Agreement” were references to this Agreement.

2. NOVATION

As and with effect from the Effective Time:

	(1)		Lessee releases Existing Lessor from Existing Lessor’s obligations, duties and liabilities to Lessee under the Lease Documents to the extent related to the period, and which arise, after the Effective Time;
	(2)		Existing Lessor releases Lessee from Lessee’s obligations, duties and liabilities to Existing Lessor under the Lease Documents and Existing Lessor agrees that it has no further rights under the Lease Documents, in each case, to the extent related to the period, and which arise, after the Effective Time;
	(3)		New Lessor agrees with Lessee to assume the rights, obligations, duties and liabilities of Existing Lessor under the Lease Documents, to the extent related to the period, and which arise, after the Effective Time;

	(4)		Lessee consents to and accepts the assumption by New Lessor of Existing Lessor’s rights, obligations, duties and liabilities under the Lease Documents;

The Existing Lessor, New Lessor and Lessee accordingly agree that, as and with effect from the Effective Time (subject to the satisfaction, or the waiver in accordance with Section 5.3, of the conditions precedent set out in Sections 5.1 and 5.2), the Lease Agreement shall be novated to New Lessor with the effect of constituting a new agreement in the form of the Novated Lease between New Lessor, as lessor and Lessee, as lessee.

Without prejudice to the rights of New Lessor or Lessee hereunder or under the Novated Lease, Lessee and Existing Lessor agree that, in respect only of any losses, liabilities or claims suffered or incurred by either of them in respect of the part of the Lease Period prior to the Effective Time, each shall have the same rights and remedies against each other as it would have had if Existing Lessor had remained the “Lessor” under the Lease Documents and this Agreement had not been executed. The New Lessor shall not be responsible to Lessee in respect of any such losses, liabilities or claims nor shall Lessee exercise any set off or counterclaim against New Lessor in respect of any such losses, liabilities or claims.

3. NEW LESSOR’S AGREEMENTS

Prior to the earlier of (x) the Effective Time and (y) January 31, 2011, New Lessor will deliver to Lessee:
