         Hour Agreement during the Term without first obtaining Lessor's written
         consent and in Lessor's reasonable judgement such amendment,
         supplement, extension or replacement is adverse to the interests of
         Lessor in any material respect.

         Maintenance Contribution in accordance with Section 7.2 of the CTA.

         and Section 5.7 (c) of the CTA shall apply under this Lease.

3.5      PURCHASE OPTION:

         the last day of the Term (the "Right") for an amount equal to the Fair
         Market Value of the Engine (the "Purchase Price") provided that Lessor
         shall have received prior written notice not less than 180 days before
         the last day of the Term (the "Notice") of Lessee's intention to
         exercise the Right.

         For the purposes of this Clause 3.5 "Fair Market Value" shall mean such
         amount as is agreed between Lessor and Lessee (such amount shall be
         determined not more than 180 days prior to the last day of the Term) as
         the expected fair market value of the Engine on the last day of the
         Term or failing agreement as to such expected fair market value, such
         amount as shall be determined in Dollars by an independent expert
         appointed by Lessor and an independent expert appointed by Lessee. If
         either party shall not have indicated in writing to the other within
         fourteen (14) days after the failure by the parties to agree upon the
         expected fair market value of the Engine of the appointment of its
         independent expert, the expected fair market value shall be the amount
         determined by the independent expert whose appointment has been
         notified in writing to the other party. If the independent experts
         appointed by the parties fail to agree upon the expected fair market
         value of the Engine within fourteen (14) days of their appointment, the
         independent experts shall jointly appoint a third independent expert
         who shall determine the expected fair market value of the Engine within
         14 days of his appointment and whose decision shall be final and
         binding upon all the parties. If the independent experts are unable to
         agree upon the third independent expert within 10 days of the expiry of
         such 14 day period, such third independent expert shall be selected by
         the American Arbitration Association. The expected fair market value of
         the Engine on the last day of the Term shall be determined on the basis
         that:

         in which event such costs shall be for the account of Lessee. For a
         period of ten (10) Business Days following the date that the Fair
         Market Value is determined, Lessee shall be entitled by written notice
         to Lessor to revoke its exercise of the Right, after which time

         Lessor in respect of such Engine and remaining in the Engine LLP

PART II-DELIVERY CONDITION REQUIREMENTS

Set forth below is a description of the condition in which each Engine must be
in order for Lessee to be obligated to accept such Engine under the Lease. It is
solely a description of such condition precedent and shall not be construed as a
representation, warranty or agreement of any kind whatsoever, express or
implied, by Lessor with respect to the Engine or its condition, all of which
have been disclaimed by Lessor and waived by Lessee as set forth in the Lease,
including in the CTA.

DELIVERY CONDITION REQUIREMENTS:

Used Engines: ESN CAE311434; CAE311206; CAE311635; CAE311794; CAE311908; "as is,
where is" pursuant to the terms of the Purchase Agreement.

New Engines: two engines ESN CAE312096 and CAE312071, and two engines ESN to be
determined shall be new, bare, ex-factory certificated for operation at 7,400
pounds with engine stand, engine cover, LRU, other accessories and Engine

                                   SCHEDULE A

                     PART III- RETURN CONDITION REQUIREMENTS

In addition to and supplementing Lessee's obligations set forth in Clause 12 and
Schedule 6 of the Common Terms Agreement, Lessee shall redeliver the Engine to
Lessor on the Return Occasion meeting the following requirements:

Lessee shall redeliver the Engines with on average no fewer than 3,200 Engine
Flight Hours remaining to the next expected Engine Refurbishment and on average
no fewer than 3,200 Engine Cycles remaining on the Life Limited Parts to the
next limiter, and with no one Engine having fewer than 1,600 Engine Flight Hours
to the next expected Engine Refurbishment and with each Engine having a minimum
of 1,600 Engine Cycles life remaining on Life Limited Parts to the next limiter.
For avoidance of doubt, the foregoing average and minimum condition standards
shall be calculated without reference to any Engine as to which Lessee has
exercised its Right to purchase in accordance with Section 3.5 hereof and has
performed its purchase obligation with respect thereto. In the event that any
Engine fails, or the Engines as a group fail by 10% or more, to satisfy the
return condition requirements, Lessee shall be obligated to purchase the
deficient Engine, or in the case of the group of Engines failing, such number of
the most deficient Engines as is necessary for the remaining Engines to satisfy
the return conditions; provided, however, that in lieu of purchasing up to two
such deficient Engines Lessee may elect to provide up to two Suitable Substitute
Engines (as herein defined) as replacements for such deficient Engines. If
Lessee is required to purchase one or more of the Engines pursuant hereto, the
purchase price shall be determined in the same manner as provided in Section 3.5
and the sale shall be made on the same basis as provided in Section 3.5. If
Lessee elects to provided a Suitable Substitute Engine, Lessor will convey the
Engine that such Suitable Substitute Engine replaces to Lessee on the same basis
as provided in Section 3.5 (excluding the payment of a purchase price) and
Lessee shall convey such Suitable Substitute Engine pursuant to a full warranty
bill of sale in form reasonably acceptable to Lessor. As used herein, "Suitable
Substitute Engine" means an engine that complies with all the terms and
conditions of this Lease (including, without limitation, compliance with all
return conditions), and that is in substantially the same or a better condition
that the Engine it will replace as to (i) maintenance status in relation to the
number of Flight Hours of operation since its last Engine Refurbishment, (ii)
LLP value profile, (iii) modification status, and (iv) expected life remaining
to the next Engine Refurbishment.

the following conditions are fulfilled: (1) such disclosure shall be limited to
the information that is required by applicable Law; (2) prior to such disclosure
being made by Lessee, the form of the proposed disclosure shall be presented to

         to Owner under this Clause, Owner shall be assumed to be subject to a
         combined U. S. and state income tax rate of (after giving effect to the
         deductibility of such state income taxes for U. S. income tax purposes)
         38% in 2001 and in each year thereafter (the "ASSUMED TAX RATE"), and
         the Owner will be assumed to have sufficient taxable income to be taxed
         at the Assumed Tax Rate after full utilization of the MACRS Deductions.
         The amount payable under this indemnity shall be the amounts required
         from time to time, which, after deduction by Owner of the amount of all
         additional U. S., state, local, and foreign taxes required to be paid
         by Owner in respect of the receipt or accrual of such amount, will
         equal the increase in income taxes payable by (or not refundable to)
         Owner as the result of such MACRS Loss, plus the amount of any actual
         interest, penalties, and additions to tax payable by Tax Indemnitee
         with respect to such MACRS Loss.

(ii)     If, as the result of a MACRS Loss, the amount of the U. S. income taxes
         payable by Owner for any taxable year shall be less than the amount of
         such taxes that would have been payable by Owner had such MACRS Loss
         not occurred (or as the result thereof, Owner shall receive a refund of
         U. S. income taxes payable that shall be greater than the amount of
         such refund , if any, that Owner would have received had such MACRS
         Loss not occurred), then Owner shall pay to the Lessee the amount of
         such increased reduction in taxes (or refund, including any actual
         interest (net of any taxes payable with respect to such interest)
         received thereon), plus any net additional U. S., state, local, or
         foreign tax benefits actually realized by Owner as the result of any
         payment made pursuant to this sentence (such reduction in, or increased
         refund of, income taxes to be determined on a hypothetical basis, I.E.,
         assuming Owner can utilize any additional tax benefits resulting from
         the MACRS Loss at the Assumed Tax Rate); provided, however, that the
         amount payable by Owner pursuant to this sentence shall not exceed the
         sum of the amounts previously paid by the Lessee to Owner pursuant to
         the preceding paragraph with respect to such MACRS Loss to the extent
         not previously taken into account under this sentence.
