IT IS AGREED as follows:

     same meanings ascribed thereto pursuant to the Lease. The provisions of
     Clause 1.2 of the Lease apply as if set out herein, mutatis mutandis.

<PAGE>

refer to the accounts most recently provided by Lessee to Lessor prior to the
date of this Amendment Agreement.

3.   AMENDMENTS TO LEASE

3.1. TERM: Clause 4.2 of the Lease is hereby amended by adding the words "and
     Term" to the word "Commencement" in the heading; and by adding a new
     paragraph to the end thereof as follows:

          "Provided that the Aircraft has not been earlier redelivered in
          accordance with this Agreement, this Agreement has not earlier been
          terminated in accordance with its terms, or Lessor has not earlier
          received the Agreed Value following an Event of Loss, the Term shall,
          unless the parties otherwise agree, be automatically extended for
          successive periods of one year (each an "Extension Term") up to a
          maximum term ending June 21, 2009 (but subject to an additional
          extension of one year, at Lessee's choice, commencing June 22, 2009
          and ending June 21, 2010, provided that no Event of Default shall have
          occurred and be continuing at the time of such election and as of June
          21, 2009 and that Lessee shall have given Lessor written notice
          (which, once given, shall be irrevocable) of its election to so extend
          the Term not less than 12 months prior to June 21, 2009) and the
          definition of "Expiry Date" set forth in Section 1.1 of the Lease
          shall be construed accordingly".

3.2  RENT: With effect from May 1, 2003, the definition of "Rent" set forth in
     Annex A to the Lease is amended by deleting paragraphs (1) and (2) thereof
     in their entirety and substituting the following:

          "(1) For the period commencing on May 1, 2003 and throughout each
          yearly Extension Term up to and until June 21, 2009, $**Material
          Redacted** per Rental Period;

          (2) Should Lessee elect to extend the Lease from June 22, 2009 until
          June 21, 2010 as set forth in Clause 4.2 of the Lease (as amended by
          Clause 3.1 of the Aircraft Amendment Agreement), each installment of
          Rent in respect of each Rental Period shall be calculated on the basis
          of an assumed rent of $**Material Redacted** per month (the "Assumed
          Rent"). The Assumed Rent is calculated on the assumption that the
          "Applicable LIBOR" (being 12-month The Bank of Tokyo-Mitsubishi, Ltd.
          LIBOR as quoted to Lessor two banking days prior to June 22, 2009) is
          **Material Redacted**% per annum. To the extent that the Applicable
          LIBOR is higher or lower than **Material Redacted**% per annum, the

<PAGE>

          Assumed Rent shall be increased (in the case where the Applicable
          LIBOR is higher than **Material Redacted**% per annum) or reduced (in
          the case where the Applicable LIBOR is lower than **Material
          Redacted**% per annum) by $** Material Redacted** each **Material
          Redacted**% difference between Applicable LIBOR and **Material
          Redacted**% per annum (and pro rata for fractions of a per cent) to
          determine the Rent payable by the Lessee on the Rent Dates for each
          Rental Period occurring on or after June 22, 2009."

3.3. BLENDED WINGLETS: Schedule 4 to the Lease is hereby amended by adding the
     following as paragraph 1.7 thereof:

          "Lessor and Lessee agree to the installation of the blended winglets
          on the Aircraft during any period where it can be reasonably scheduled
          prior to Redelivery without affecting the commercial program of the
          Aircraft. Lessor and Lessee shall compare the cost of material and
          installation available to each of Lessor and Lessee under their
          respective agreements (collectively, the "APB ARRANGEMENTS") with
          Aviation Partners Boeing ("APB") and the procurement and installation
          of the winglets shall be made under and pursuant to the less expensive
          of the two APB arrangements. Lessor shall either pay to APB the full
          cost of labor and equipment or reimburse Lessee for same upon
          presentation to Lessor of the actual invoice. The blended winglets
          shall remain on the Aircraft at Redelivery."

3.4. ENGINE DERATE: Notwithstanding any other provision of the Lease, Lessor
     consents to Lessee's decreasing the Engine take-off thrust rating from
     24,000lbs. to 22,000lbs. after installation of the blended winglets subject
     to receipt by Lessor of prior written confirmation (in form and substance
     satisfactory to Lessor acting reasonably) from the Engine Manufacturer that
     returning the Engine take-off thrust rating to 24,000lbs. will not result
     in any cost and, further, the parties agree that Schedule 4 to the Lease is
     hereby amended by adding the following as paragraph 3.6 thereof:

          "The take-off thrust rating of the Engines shall be not less than
          24,000lbs at Redelivery".

3.5. LETTERS OF CREDIT: Clause 5.1.10 of the Lease is hereby amended by deleting
     both references therein to "10 days" and by substituting therefor
     references to "thirty (30) days." Lessor and Lessee agree to attempt in
     good faith to consolidate the Deposit Letter of Credit and the Supplemental
     Letter of Credit on terms acceptable to both parties

<PAGE>

3.6. MAINTENANCE PAYMENT: Clause 5.3.2(1) of the Lease is hereby amended by
     deleting the words "during the first 54 months of the Term" and
     substituting therefor the words "during the 24 month period immediately
     preceding the date falling six months prior to expiry of the Term".

3.7  AGREED VALUE: Annex A to the Lease is hereby amended by deleting the
     reference in the definition of "Agreed Value" to "$**Material Redacted**"
     and substituting therefor: "$**Material Redacted** to be decreased by
     $**Material Redacted** upon each annual renewal of Lessee's fleet policies
     during the remainder of the Term".

4.   OTHER AGREEMENT

4.1. AIRCRAFT SYSTEM MODIFICATIONS: Lessor and Lessee will separately negotiate
     in good faith to agree to incorporate (such incorporation to be completed
     on or before June 1, 2004) certain system upgrades (based on a mutually
     agreed upon listing of "approved system upgrades") on the Aircraft, and
     Lessor shall pay up to an aggregate cap of US $**Material Redacted** for
     such upgrades. Lessor and Lessee agree to amend the Lease being at that
     time to reflect any such agreement as to incorporation of system upgrades
     and to reflect a corresponding increased adjustment to the Rent with effect
     from completion of such incorporation by **Material Redacted**% per month
     times the total modification costs for such incorporation. For the
     avoidance of doubt, nothing in this Clause 4.1 shall constitute an
     amendment to the Lease. For the avoidance of doubt, the cap referenced
     above and the rent adjustment factor detailed above do not pertain to cost
     of installation of the blended winglets referenced in Clause 3.3 above.

4.2. ENGINE MAINTENANCE: Lessee will discuss with a qualified engine maintenance
     services provider acceptable to Lessor acting reasonably for such provider
     to cover the maintenance of the Engines of the Aircraft ("ENGINES")
     pursuant to an agreement between such provider and Lessee which shall be in
     form and substance satisfactory to Lessor (in the reasonable opinion of
     Lessor). Lessor and Lessee agree to amend the Lease, as may be required to
     reflect any agreement between them in respect of maintenance of the
     Engines, which may deviate from the provisions concerning maintenance of
     the Engines currently set forth in the Lease. For the avoidance of doubt,
     nothing in this Clause 4.2 shall constitute an amendment to the Lease.
