August 14, 1997 (Continued)

                    Engine Record Data To Be Provided To WLFC

      1.    Bill of Sale for each Engine.

      2.    Letter and documentation stating the reason for removal of each
            Engine which shall  include a Form 8130-3 or JAA Form.

      3.    Life Limited parts sheet signed by Air India for each Engine.

      4.    Material Certification form from Air India and/or PW for each
            Engine, as applicable.

      5.    Log sheet defining any work performed by Air India on each Engine.

      6.    Documentation and verification defining the preservation performed

            Whitney specifications prior to Delivery.

      On behalf of WLFC, PWES will put forward reasonable efforts to obtain any
      of the above Engine Documentation that WLFC requires from Air India.
      Additionally, PWES shall provide copies of the Pratt & Whitney original
      build documentation for each Engine.

2.5   PWES will be under no obligation to ship an Engine if there is a previous
      invoice outstanding by WLFC to PW which exceeds PW's outstanding invoice
      balance to WLFC.

2.6   Within at least fifteen (15) days prior to Delivery notification of any
      specified Engine described in this Agreement by WLFC to PW, WLFC and PW
      shall mutually agree whether each Engine to be Delivered shall be either
      leased or disposed of for its modules and component parts. PW shall be
      granted by WLFC the "right of first refusal" to lease each such Engine as
      Delivery notification is exercised by WLFC. When a lease is mutually
      agreed to by the parties, the Lease Support Agreement by and between WLFC
      and PW shall govern. When WLFC determines that a PW engine as described in

      of WLFC or its affiliates (such PW Engine being referred to as an
      unserviceable Engine), WLFC will dispose of such Engine(s), and the

      Disposition Agreement.

      which shall exclude the programming plugs. WLFC shall return

      to PW the specified PW4056 data plates in exchange for PW4060 data plates.
      WLFC shall so identify the subject first two (2) Engines by serial number
      from the Engines specified in this Agreement at the time of or prior to
      the delivery to WLFC to which Engines the data plates shall be assigned.
      WLFC shall cause each of the subject first two (2) Engines to be
      overhauled and modified by PW at PW's Cheshire, Connecticut facility to
      the PW4060 thrust rating. It is contemplated that the third and fourth
      engines that WLFC selects at its sole discretion, whether part of this
      Agreement or otherwise, may be, but not necessarily, overhauled or
      modified by PW's Cheshire Connecticut facility. This data plate
      provisioning has an estimated value of Three Hundred and Forty-Seven
      Thousand, Eight Hundred Dollars ($347,800.00) per Engine to WLFC.

2.8   PW shall grant WLFC the "right of first refusal" to competitively bid on
      the purchase of PW engine serial number 727391, if PW decides to sell said
      Engine, and which is not part of this Agreement.

                               ARTICLE 3.0 - TAXES

      for, all property, sales, use, excise or any other similar taxes and
      customs or other duties which are based upon the purchase and sale or any
      subsequent use, operation or possession of the Engine (the "Taxes"),
      exclusive of taxes on or measured by PWES's income. WLFC shall promptly
      remit to PWES or the proper taxing authority and shall indemnify, defend
      and hold PWES, its officers, employees and directors, harmless for and
      against all such Taxes, interest and penalties assessed, and reasonable
      attorneys' fees incurred in connection with the payment or collection of
      such Taxes.

      (b)   The provisions of this Article 3.0 shall survive the completion of
            the transactions contemplated by this Agreement and its earlier
            cancellation or termination.

              ARTICLE 4.0 - INSPECTION, DELIVERY, TITLE, RISK OF LOSS

      bank that the payment has been received in accordance with Article 2.0

      WLFC with an executed Bill of Sale evidencing WLFC's ownership of the
      Engine.

      (b)   Upon Delivery of the Engine to WLFC, WLFC shall bear full risk of
            loss of, or damage to, the Engine. Upon execution by WLFC of the
            Engine Inspection Acknowledgment Receipt, WLFC shall be responsible
            for any technical discrepancies in the Engine and the Engine
            Documentation which it has accepted.

      (c)   Title to each Engine shall pass to WLFC upon Delivery.

4.3   Delivery Schedule. The Engine Delivery and payment plan schedule for each
      Engine shall begin as mutually agreed and further described in the table
