2.   AMENDMENTS

     The Sale and Purchase Agreement is amended as follows:

2.1  The introductory clause of Clause 2.2 is hereby amended and restated to
     read in its entirety as follows:

     "Upon the terms and subject to the conditions set forth in this Agreement,
     on the Closing Date (or, (i) with respect to any Material Contract related
     to any Deferred Partnership Asset Owning Entity, the relevant Deferred Date
     or (ii) with respect to any other Additional Assets, such other date as
     Buyer and Seller may agree), Seller shall, or shall cause an Other Selling
     Party to, sell, assign, convey, transfer and deliver to Buyer or, if so
     requested by Buyer, to an Affiliate of Buyer reasonably acceptable to
     Seller, and Buyer shall, or shall cause the relevant Affiliate of Buyer as
     aforesaid to, purchase, acquire, accept and assume, all of the right, title
     and interest of the applicable Selling Party in and to the following
     (collectively, the "ADDITIONAL ASSETS"), as such Additional Assets exist on
     the Closing Date (or the relevant Deferred Date or other date as Buyer or
     Seller may agree, as the case may be):".

2.2  The introductory clause of Clause 2.5 is hereby amended and restated to
     read in its entirety as follows:

     "Upon the terms and subject to the conditions of this Agreement, Buyer
     agrees that it shall, or it shall cause its Affiliate to whom any
     Additional Assets related to any of the Liabilities described below are
     transferred pursuant to Clause 2.2 of this Agreement to, effective at the
     Closing (or such other dated as Buyer and Seller may agree) to assume from
     the Selling Parties and to satisfy and discharge when due the following
     specific Liabilities, other than the Retained Liabilities (the "ASSUMED
     LIABILITIES"):"

2.3  The following provision is hereby inserted as Clause 2.11:

     "2.11 Transfers to Affiliates

     Notwithstanding anything to the contrary contained in this Agreement, it is
     understood and agreed that if and to the extent any Additional Assets are
     transferred to an Affiliate of Buyer (rather than to Buyer itself) pursuant
     to the terms of Clause 2.2 and/or an


                                       -2-



     Affiliate of Buyer (rather than Buyer itself) assumes any Assumed
     Liabilities pursuant to the terms of Clause 2.5, Buyer shall nonetheless
     remain directly obligated for all of its obligations hereunder, including
     with respect to such Additional Assets.".

2.4  Clause 6.5.1 is hereby amended as follows:

     Subject to Seller's receipt of the payment contemplated by the following
     sentence, Buyer and Seller agree that, in respect of that certain Focused
     Air Aircraft Airbus A320-200 aircraft bearing manufacturer's serial number
     331 (the "Affected Aircraft"), the provisions of Clause 6.5.1 of the Sale
     and Purchase Agreement related to proceeds from the sale of the Affected
     Aircraft are no longer effective and Seller shall have no right to a
     payment in respect of the sale of the Affected Aircraft under said Clause
     6.5.1. As consideration for Seller waiving its right to any such payment,
     Buyer agrees that, concurrently with its purchase of the third-party
     interests in GATX/CL Air (the "Third-Party Interests"), Buyer shall pay
     Seller, by wire transfer of immediately available funds, an amount equal to
     (a) $2,828,228.40 minus (b) the aggregate amount of all rental proceeds
     paid by Buyer to Seller pursuant to Clause 6.5.1 of the Sale and Purchase
     Agreement in respect of the Affected Aircraft between (and including) March
     26, 2007 through (and including) the May 29, 2007) plus (c) the aggregate
     amount of all maintenance reserves and other payments made by Seller in
     respect of the Affected Aircraft between (and including) March 26, 2007
     through (and including) the May 29, 2007) plus (d) interest accrued at 7%
     per annum from time to time on the amount equal to (a) minus (b) plus (c)
     from March 26, 2007 until the date Buyer pays such amount. Although Buyer
     is purchasing the Third-Party Interests on an aggregate basis and,
     therefore, the Affected Aircraft has not been individually valued in
     connection therewith, Buyer hereby represents and warrants to Seller that
     the amount that Seller is receiving for its share of the Affected Aircraft
     is, in Buyer's reasonable opinion, reasonably equivalent to the amount that
     the other partners of GATX / CL Air could reasonably be expected to
     allocate to the Affected Aircraft in connection with their sale of the
     Third-Party Interests to Buyer. For the avoidance of doubt, it is
     understood and agreed that, notwithstanding the foregoing, Buyer shall
     continue to be obligated to pay Seller its portion of any incentive fees
     received by GATX/CL Air pursuant to the terms of Clause 6.5 of the Sale and
     Purchase Agreement.

2.5  The following provision is hereby added at the end of Clause 7.11:

     "It is the intention of Buyer and Seller that Seller's remarketing
     obligations under the A321 GTL Documents (the "Remarketing Obligations") be
     transferred to, and assumed by, Buyer. If a direct transfer of the
     Remarketing Obligations is not possible, then Buyer and Seller will in good
     faith determine an alternative structure (such as a subcontracting or
     similar arrangement) whereby Buyer performs the Remarketing Obligations on
     Seller's behalf. Regardless of the structure that is used, it is the
     intention of the parties that any benefits and liabilities associated with
     the Remarketing Obligations (including any payments received by Seller in
     connection with the Remarketing Obligations) be for the account of Buyer."


                                       -3-



3.   ADDITIONAL DESIGNATED CONTRACTS

defined in that certain Assignment and Assumption Agreement being entered into

"Additional Designated Contracts") shall each be a "Designated Contract" for
purposes of the Agreement:

     Each of Buyer and Seller agree that the amount owing by Seller to Buyer in
connection with the working capital adjustment contemplated by Clause 6.1 hereof
shall be reduced by $5,000 in order to reimburse Seller for certain
out-of-pocket costs and expenses (including, without limitation, fees of outside

respect to an unpaid loan (balance $735,687), unpaid reserves (balance
$966,327.69), return condition claims ($7,800,000) and/or unpaid rent (balance
$810,000) (collectively, "Varig Claims") shall transfer to Buyer. Buyer shall
promptly disburse to Seller 50% of any amounts (a) recovered by Buyer with
respect to any Varig Claims or (b) received by Buyer from any sale of any Varig
Claims, in each case net of expenses incurred by Buyer in connection with
obtaining such recoveries or making such sales. Notwithstanding the foregoing,
it is understood and agreed that Buyer shall have no obligation to take any
actions with respect to or otherwise pursue any Varig Claims. If Buyer does
pursue any Varig Claims, Seller shall provide Buyer with access to any documents
in Seller's possession that Buyer may reasonably request in connection
therewith.

5.   TAX LEASES

     For the avoidance of doubt and without limiting the provisions of Clauses
7.11 and 7.12, Buyer shall continue to use its reasonable best efforts to obtain
the release of Seller from the guarantees referenced in Clauses 7.11 and 7.12.

6.   WORKING CAPITAL ADJUSTMENT

     6.1 Buyer and Seller hereby agree that attached as Exhibit A to this
Seventh Supplement Agreement is a document setting forth the Closing Working
Capital as agreed upon


                                       -4-

previous sentence, each of Buyer and Seller acknowledge and agree that they have
not yet reached agreement on the treatment of the following two items for
purposes of the calculation of the Final Closing Working Capital: (x) a payment
in the amount of $343,535.67 received by Seller on November 28, 2006 and (y) a
transposition error in the amount of $4,000 on a Vueling Payment (collectively,
the "Disputed Items"). Each of Buyer and Seller acknowledge and agree that they
shall work in good faith to reach agreement with respect to the Disputed Items
as soon as reasonably practicable after the date hereof. In accordance with the
terms the Sale and Purchase Agreement and based on the calculation of the Final
Closing Working Capital (as modified by the resolution of the Disputed Items if
applicable), Buyer and Seller further hereby agree that Seller shall, promptly
after the resolution of the Disputed Items, pay to Buyer an amount ranging from
$1,169,416.82 or $881,821.15 (depending on the resolution of the Disputed Items)
plus interest thereon as determined in accordance with Clause 2.8 of the Sale
and Purchase Agreement (the "Working Capital Settlement Amount"). Each of Buyer
and Seller hereby acknowledge and agree that the payment of the Working Capital
Settlement Amount by Seller to Buyer represents the final settlement of any
claims among the parties with respect to the Working Capital of the Business
(whether pursuant to the Sale and Purchase Agreement or otherwise) and,
effective upon payment by Seller to Buyer of the agreed Working Capital
Settlement Amount, each of Buyer and Seller (on behalf of themselves and their
respective Affiliates) hereby fully and unconditionally releases the other party
(and such other party's respective Affiliates) from any such claims.

7.   SUPPLEMENTAL AGREEMENTS
