     WHEREAS, ARI and ACF are parties to that certain Manufacturing Services Agreement dated as of October 1, 1994 (the “Manufacturing Agreement”);

     WHEREAS, pursuant to the Manufacturing Agreement, ACF is providing ARI certain Jobbing Order Services (as defined in the Manufacturing Agreement), which include, among other things, the assembly of railcar wheel sets;

     WHEREAS, the Manufacturing Agreement contemplates that ARI may supply the materials for use by ACF in ACF’s performance of its Jobbing Order Services, and further provides alternative pricing for the Jobbing Order Services depending upon whether ARI or ACF purchase such materials;

     WHEREAS, ARI is in the business of manufacturing railcars and railcar wheel sets are a critical component of railcars, and ARI and ACF desire that ARI control the procurement of and own the components for the railcar wheel sets, comprising of wheels, axles and bearings (the “Wheel Set Components”), for use by ACF in performing its Jobbing Order Services;

     WHEREAS, in connection therewith, ACF agrees to provide certain accommodations to ARI, as provided herein, to ensure the proper care, storage, use and identification of Wheel Set Components purchased by ARI for use by ACF in performing its Jobbing Order Services and the railcar wheel sets assembled using such components (the “Finished Wheel Sets”); and

     WHEREAS, in order to evidence the terms under which ACF will maintain possession of the Wheel Set Components owned by ARI and the Finished Wheel Sets, the parties have agreed to enter into this Wheel Set Component and Finished Wheel Set Storage Agreement;

     NOW, THEREFORE, in consideration of these premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, ACF and ARI agree as follows:

     1.     Procurement of Wheel Set Components. ARI shall be responsible for purchasing the Wheel Set Components for use by ACF in its manufacture of railcar wheel sets for ARI pursuant to the Manufacturing Agreement. ARI shall also be responsible for arranging for and payment of delivery of the Wheel Set Components to ACF in connection therewith. The parties understand that ACF has previously purchased Wheel Set Components for the manufacture of Finished Wheel Sets for ARI that, prior to the date hereof, have not been

purchased by ARI and are currently owned by ACF. Such Wheel Set Components, including any Finished Wheel Sets incorporating such Wheel Set Components that have not yet been purchased by ARI, shall be referred to as the “ACF Wheel Set Inventory.” ACF hereby represents and warrants that a true and correct list of the ACF Wheel Set Inventory and the cost thereof (as represented by the purchase price paid or, as of immediately prior to the date hereof, payable by ACF for the purchase by ACF of the ACF Wheel Set Inventory) has been provided to ARI along with a schedule showing the vendor, the purchase order number, the amount paid and, as of immediately prior to the date hereof, the amounts outstanding for the payment by ACF of the purchase price for the ACF Wheel Set Inventory. ACF agrees to pay vendors in full, on the date hereof, all outstanding amounts payable as of immediately prior to the date hereof for all ACF Wheel Set Inventory. ARI hereby agrees to purchase from ACF, and ACF herby agrees to sell to ARI, the ACF Wheel Set Inventory as of the date hereof for a purchase price equal to said cost of the ACF Wheel Set Inventory to ACF. The purchase price shall be payable by ARI to ACF (a) on the date hereof as to amounts previously paid by ACF for such inventory, and (b) promptly upon ARI’s receipt of evidence reasonably satisfactory to ARI of ACF’s payment in full of all outstanding amounts payable as of immediately prior to the date hereof. ACF agrees to provide ARI with such information as ARI reasonably requests to verify the costs and accounts payable outstanding, as of immediately prior to the date hereof, in respect of the ACF Wheel Set Inventory. Any such ACF Wheel Set Inventory so purchased by ARI shall be owned by ARI as of the date hereof, shall be treated as supplied by ARI for purposes of determining amounts owed to ACF for its Jobbing Order Services in manufacturing Finished Wheel sets for ARI under the Manufacturing Agreement (which shall remain payable as set forth in the Manufacturing Agreement), and shall constitute Specified Goods as further defined herein.

     2.     Identifying Specified Goods; Documentation.
