                            Aircraft Lease Agreement

     This is a LEASE EXTENSION AND AMENDMENT AGREEMENT dated as of April 30,
2003 to the Aircraft Lease Agreement dated as of November 18, 1998 (the "Lease
Agreement") between AVIATION FINANCIAL SERVICES, INC. ("Lessor"), and COMPANIA
PANAMENA DE AVIACION, S.A. ("Lessee") as the Lease Agreement has been heretofore
supplemented, amended and modified by Lease Supplement No. 1 dated October 14,
1999 ("Lease Supplement No. 1"), by Letter Agreement No. 1 dated as of November
18, 1998 ("Letter Agreement No. 1") and by Letter Agreement No. 2 dated as of
March 8, 1999 ("Letter Agreement No. 2"), in each case between Lessor and Lessee
(the Lease Agreement as so supplemented, amended and modified is hereinafter
referred to as the "Lease").

     WHEREAS, the Lease is in respect of one Boeing 737-7V3 Aircraft
Manufacturer's Serial No. 30049 and Registration No. HP-1371CM, together with
two CFM International Model CFM 56-7B24 engines bearing manufacturer's serial
numbers 875941 and 875873 and certain related equipment (the "Aircraft"), and

     WHEREAS, Lessee and Lessor desire to extend the Term of the Lease and to
amend certain other terms thereof; and

     WHEREAS, capitalized terms used and not otherwise defined herein shall have
the meanings ascribed to them in the Lease.

     NOW THEREFORE, in consideration of the mutual covenants and agreements
contained herein, the parties hereto agree as follows:

1.   Amendments to Lease.

     The Lease is hereby amended as follows:

     A.   Section 3(g) is hereby amended and restated as follows:

               "(g) Lease Term Renewal Options: Lessor hereby grants Lessee the
          right to renew the lease for up to three (3) additional, consecutive
          terms (each a "Renewal Term") (the option to renew for each Renewal
          Term being hereafter referred to as the "Lease Term Renewal Option").
          Each Renewal Term shall consist of twelve (12) months, and the first
          Renewal Term would commence the day following the Expiration Date of
          the Basic Term. Exercise of each Lease Term Renewal Option shall be
          subject to (i) the delivery by Lessee of written notice to Lessor (a
          "Renewal Notice") as to such exercise at least nine (9) months prior
          to the then applicable Expiration Date, and (ii) no Event of Default
          having occurred and continuing on or as of the date the Renewal Notice
          is received by Lessor or the first Basic Rent Payment Date of the
          applicable Renewal Term. The


                                        1

<PAGE>

          Basic Rent during any such Renewal Term shall be payable monthly in
          advance at the same monthly Basic Rent rate paid by Lessee during the
          Basic Term (as extended by any previous extension or exercise of a
          Lease Term Renewal Option) that would otherwise be expiring. Upon
          commencement of a Renewal Term the Basic Term shall be deemed extended
          so that the new Expiry Date becomes the date which occurs on the
          twelfth monthly anniversary of the Expiration Date in effect prior to
          the renewal and the new Last Basic Rent Payment Date becomes the date
          which occurs on the twelfth monthly anniversary of the Last Basic Rent
          Payment Date in effect prior to the renewal. Upon exercise of any
          Lease Term Renewal Option such Option shall be deemed extinguished and
          not be available for any subsequent re-exercise."

     B.   In Exhibit C, Part 2. DEFINITIONS OF CERTAIN TERMS, the following
          definitions are amended and restated to read:

          "BASIC RENT: The Basic Rent payable during the Basic Term shall be
          payable in one hundred twenty (120) consecutive monthly installments,
          in advance on each Basic Rent Payment Date, with each such installment
          equal to: (a) **Material Redacted** for the first twenty four monthly
          installments, (b) **Material Redacted** for the next twelve monthly
          installments, (c) **Material Redacted** for the twenty four monthly
          installments commencing with the thirty seventh (37th) installment and
          (d) **Material Redacted** for the sixty monthly installments of Basic
          Rent commencing November 1, 2004 and for each installment of Basic
          Rent during any Renewal Term which may be commenced in a period
          subsequent to the Expiration Date."

          "CASUALTY VALUE: For the period of the Lease through April 30, 2003
          **Material Redacted**; for the period May 1, 2003 through December 15,
          2004 **Material Redacted**; and for the one year period commencing

          "LAST BASIC RENT PAYMENT DATE: The Last Basic Rent Payment Date for
          the Aircraft shall be October 1, 2009, or such later date as may
          result from exercise of the Lease Term Renewal Options.

               **Material Redacted** of the Winglets Actual Cost commencing on
               the first Basic Rent Payment Date following winglet installation.
               Upon installation, such winglets shall become a part of the

               (III) FULL FACE OXYGEN MASKS, and
