          ,
2007




To Brokers, Dealers, Commercial Banks,




Trust Companies and Other Nominees:



     
We are enclosing herewith an offer by XTRA Finance Corporation,
a Delaware corporation (the “Company”), to exchange
the Company’s new 5.150% Senior Notes Due 2017 (the
“Exchange Notes”) which have been registered under the
Securities Act of 1933, as amended (the “Securities
Act”), for any and all of the Company’s outstanding
5.150% Senior Notes Due 2017 (the “Original
Notes”), upon the terms and subject to the conditions set
forth in the accompanying Prospectus,
dated           ,
2007 (as the same may be amended and supplemented from time to
time, the “Prospectus”), and related Letter of
Transmittal (which together with the Prospectus constitutes the
“Exchange Offer”).



     
The Exchange Offer provides a procedure for holders to tender
the Original Notes by means of guaranteed delivery.



     
The Exchange Offer will expire at 5:00 p.m., New York City
time,
on           ,
2007, unless extended (the “Expiration Date”).
Tendered Original Notes may be withdrawn at any time prior to
5:00 p.m., New York City time, on the Expiration Date, if
such Original Notes have not previously been accepted for
exchange pursuant to the Exchange Offer.



     
Based on an interpretation by the staff of the Division of
Corporation Finance of the Securities and Exchange Commission
(the “SEC”) as set forth in certain interpretive
letters addressed to third parties in other transactions,
Exchange Notes issued pursuant to the Exchange Offer in exchange
for Original Notes may be offered for resale, resold and
otherwise transferred by a holder thereof (other than a holder
that is an “affiliate” of the Company within the
meaning of Rule 405 under the Securities Act or a
“broker” or “dealer” registered under the
Securities Exchange Act of 1934, as amended (the “Exchange
Act”)), without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided
that such Exchange Notes are acquired in the ordinary course of
such holder’s business and such holder is not engaging,
does not intend to engage, and has no arrangement or
understanding with any person to participate, in the
distribution of such Exchange Notes. See
“Shearman & Sterling,” SEC No-Action Letter
(available July 2, 1993), “Morgan Stanley &
Co., Inc.,” SEC No-Action Letter (available June 5,
1991), and “Exxon Capital Holding Corporation,” SEC
No-Action Letter (available May 13, 1988). Accordingly,
each broker-dealer that receives Exchange Notes for its own
account pursuant to the Exchange Offer must acknowledge that it
will deliver a Prospectus in connection with any resale of those
Exchange Notes.



     
The Exchange Offer is not conditioned on any minimum aggregate
principal amount of Original Notes being tendered. Original
Notes may be tendered by each holder in a minimum aggregate
principal amount of $1,000 and integral multiples of $1,000 in
excess thereof.



     
Notwithstanding any other provisions of the Exchange Offer, or
any extension of the Exchange Offer, the Company will not be
required to accept for exchange, or to exchange any Exchange
Notes for any Original Notes and may terminate the Exchange
Offer (whether or not any Original Notes have been accepted for
exchange) or may waive any conditions to or amend the Exchange
Offer, if any of the conditions described in the Prospectus
under “The Exchange Offer — Conditions to the
Exchange Offer” have occurred or exist or have not been
satisfied.

of your nominee, we are enclosing the following documents:
