individual capacity but solely as owner trustee of the Trust. Caterpillar
Financial Services Corporation (the "Servicer") is the Servicer under a Sale and
Servicing Agreement dated May 1, 2004 among the Servicer, the Seller, and the
Trust. On May 25, 2004, the Trust issued:

 The
Certificates evidence fractional undivided interests in the Trust. The Seller
retained the entire principal amount of the Certificates. The Notes evidence
debt obligations of the Trust.
 
 The
property of the Trust includes (i) equipment retail installment sale contracts
and finance lease contracts secured by new and used machinery manufactured
primarily by Caterpillar Inc. or its affiliate Mitsubishi Caterpillar Forklift
America Inc. (the "Financed Equipment"), including rights to receive certain
payments made with respect to such contracts sold to the Trust by the Seller,
(collectively the "Receivables"), (ii) all monies (including accrued interest)
due or received thereunder on or after the applicable cutoff date, (iii)
security interests in the Financed Equipment and certain other
cross-collateralized equipment, (iv) such amounts as from time to time may be
held in one or more accounts established and maintained by the Servicer pursuant
to the Sale and Servicing Agreement or the Trust Agreement and the short-term
investments made from those collections, (v) the rights to proceeds from claims
on physical damage, credit life, or disability insurance policies, if any,
covering the Financed Equipment or the obligors on the Receivables, as the case
may be, (vi) the proceeds of any repossessed Financed Equipment, (vii) the
rights of the Seller under the related Purchase Agreement between the Servicer
and the Seller, (viii) the interest of the Seller in any proceeds from recourse
to dealers on such receivables, (ix) interest earned on short-term investments
made by the Trust, and (x) any proceeds of the foregoing.
 
 As of
December 31, 2004, the end of the fiscal year of the Trust for which this Form
10-K annual report is being filed, the aggregate principal balance of the
Receivables remaining in the Trust was approximately $488,346,743.
