                                  THE COMPANY
 
    The Company is engaged in freight transportation equipment leasing and
conducts its operations through its subsidiary, XTRA, Inc. The Company's leasing
equipment is offered in North America, predominantly in the United States, to
private fleet owners, contract and common carriers and railroads, and to
worldwide steamship lines to cover cyclical, seasonal or geographic shortages
and as a substitute for purchasing equipment. The Company's operating
subsidiaries lease, primarily on an operating basis, over-the-road trailers (as
well as older trailers for mobile storage use), intermodal trailers, chassis and
domestic containers and marine containers.
 
    The Company was organized in 1957 as a Massachusetts corporation. In 1976 it
transferred substantially all of its operating assets to XTRA, Inc., a newly
organized Maine corporation, and the Company was re-organized as a holding
company under the laws of the State of Delaware. XTRA, Inc. conducts its
operations through its subsidiaries pursuant to fleet management agreements.
Under these management agreements, which are terminable upon 30 days notice by
either party, the operating subsidiaries pay fees to XTRA, Inc. for the use of
equipment owned by XTRA, Inc. Accordingly, XTRA, Inc.'s primary source of
revenues are payments under the fleet management agreements, leasing revenues
from transportation equipment leased directly by it, as well as dividends and
advances from its subsidiaries. At December 31, 1996, 22% of XTRA, Inc.'s
consolidated assets were accounted for by its subsidiaries. For fiscal 1996,
approximately 95% of XTRA, Inc.'s consolidated revenues were accounted for by
its subsidiaries.
 
    The Company's management subsidiary, X-L-CO., INC., is located at 60 State
Street, Boston, Massachusetts 02109, and its telephone number is (617) 367-5000.
 
                                USE OF PROCEEDS
 
    Except as otherwise described in the applicable Prospectus Supplement, the
Company intends to use the net proceeds from the sale of the Securities being
offered hereby for general corporate purposes. Such purposes may include, among
others, financing capital expenditures, repayment of outstanding short-term
borrowings and long-term debt, repurchasing shares of its Common Stock through
open-market purchases or otherwise and financing acquisitions in transportation
equipment or other equipment leasing product lines. Pending such use, the net
proceeds of any offering of the Securities offered hereby may be invested
temporarily in short-term marketable securities.
 
              CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES AND
            CONSOLIDATED RATIO OF EARNINGS TO COMBINED FIXED CHARGES
                         AND PREFERRED STOCK DIVIDENDS
 
    The following tables set forth the historical ratios of earnings to fixed
charges of the Company and its consolidated subsidiaries, and of XTRA, Inc. and
its consolidated subsidiaries and the historical ratio of earnings to combined
fixed charges and preferred stock dividends of the Company and its consolidated
subsidiaries for the years indicated. For purposes of computing the consolidated
ratios of earnings to fixed charges and consolidated ratio of earnings to
combined fixed charges and preferred stock dividends, "earnings" represent
income (loss) from continuing operations before taxes and extraordinary items
plus fixed charges. "Fixed charges" for continuing operations consist of
interest on indebtedness (including capitalized interest) and the portion of
rental expense that represents interest.

Securities. The Senior Securities and related Guarantees are to be issued under
an Indenture dated as of August 15, 1994 (the "Original Senior Indenture"),
among XTRA, Inc., the Company, as Guarantor, and The First National Bank of
Boston, as Trustee (the "Bank of Boston"), as supplemented by the First
Supplemental Indenture dated as of September 30, 1994 among XTRA, Inc., the
Company, as Guarantor, XTRA Missouri, Inc., as Guarantor, and the Bank of Boston
(the "First Supplemental Indenture") and as supplemented by The Second
Supplemental Indenture among XTRA, Inc., the Company and State Street Bank and
Trust Company, as Trustee (the "Second Supplemental Indenture", and, together
with the First Supplemental Indenture and the Original Senior Indenture, the
"Senior Indenture"), which Senior Indenture is incorporated by reference as an
exhibit to this Registration Statement. On October 2, 1995, State Street Bank
and Trust Company succeeded to all or substantially all of the corporate trust
business of the Bank of Boston, thereby becoming the successor Trustee pursuant
to the terms of the Senior Indenture (hereinafter the "Senior Trustee").
Effective September 30, 1996, XTRA Missouri, Inc., an intermediary holding
company of which XTRA, Inc. was a wholly-owned subsidiary and which, in turn,
was a wholly-owned subsidiary of the Company, was merged with and into the
Company, thereby transferring all of its assets and liabilities to the Company.
The Subordinated Securities and related Guarantees will be issued under an
Indenture (the "Subordinated Indenture") to be entered into among XTRA, Inc.,
the Company, as Guarantor and a trustee to be designated prior to the issuance
of any such Subordinated Securities, the form of which Subordinated Indenture is
also filed as an exhibit to the Registration Statement. Information regarding
the trustee (the "Subordinated Trustee") under the Subordinated Indenture will
be included in any Prospectus Supplement relating to such Subordinated
Securities. The Senior Indenture and the Subordinated Indenture are sometimes
collectively referred to herein as the "Indentures;" the Senior Trustee and the
Subordinated Trustee are sometimes collectively
 
                                       5

referred to herein as the "Trustees" and individually as a "Trustee." The
following summary of certain provisions of the Indentures does not purport to be
complete and is subject to, and qualified in its entirety by reference to, all
the provisions of the Indentures, including the definitions therein of certain
terms. Wherever particular provisions of defined terms of the Indentures are
referred to, such provisions or defined terms are incorporated herein by
reference. Certain defined terms in the Indentures are capitalized herein.
References in parentheses are to the Indentures.
 
GENERAL
 
    The Indentures provide that unsecured Debt Securities of XTRA, Inc., not
limited in aggregate principal amount, may be issued in one or more series
thereunder. (Section 3.1) As of December 31, 1996, XTRA, Inc. had a total of
$550,500,000 principal amount of Debt Securities outstanding under the Senior
Indenture, consisting solely of its Series C Medium-Term Notes. The Senior
Securities will be unsecured obligations of XTRA, Inc. and will rank on a parity
with all other unsecured and unsubordinated indebtedness of XTRA, Inc. Unless
otherwise indicated in the applicable Prospectus Supplement, the Subordinated
Securities will be unsecured and subordinated in right of payment to all
existing and future Senior Indebtedness of XTRA, Inc., in the manner and to the
extent described below under "Subordination of Subordinated Securities." XTRA,
Inc.'s sources of payment of the Debt Securities are payments under fleet
management agreements with certain of its subsidiaries, leasing revenues from
transportation equipment leased directly by it and advances and dividends from
its subsidiaries. In any liquidation, foreclosure or other similar proceeding,
creditors of the subsidiaries of XTRA, Inc. will be entitled to payment of
obligations owed to them before any assets are distributed to XTRA, Inc. See
"The Company."
 
    The Debt Securities will be unconditionally guaranteed by the Guarantor as
to payment of principal, premium, if any, and interest, except that the
Subordinated Securities will be guaranteed on a subordinated basis. (Section
2.2) See "Guarantees."

of any payment of principal of, premium, if any, or interest on the Debt
Securities will be determined; (14) the portion of the principal amount of such
Debt Securities which will be payable upon declaration of acceleration of the
Maturity thereof, if other than the stated principal amount thereof; (15) if the
principal amount payable at the Stated Maturity of any of the Debt Securities
will not be determinable as of any one or more dates prior to the Stated
Maturity, the amount which will be deemed to be such principal amount as of any
such date for any purpose, including the principal amount thereof which will be

    Principal, premium, if any, and interest will be payable, and such Debt
Securities will be transferable, in the manner described in the Prospectus
Supplement relating to such Debt Securities. The maturities and interest rates
of certain Debt Securities sold through underwriters or agents may be fixed by
XTRA, Inc. from time to time, in which case no specific maturities or rates, but
rather permissible ranges of such maturities and rates will be set forth in the
Prospectus Supplement relating thereto.
 
    Unless otherwise indicated in the Prospectus Supplement relating thereto,
the Debt Securities will be exchangeable and transfers thereof will be
registrable at the offices or agencies of XTRA, Inc. maintained for such
purpose, initially in the case of the Senior Securities at the Corporate Trust
Office of the Senior Trustee in Boston, Massachusetts. In New York City, Senior
Securities may be presented for transfer or exchange at the office of the Senior
Trustee located at 61 Broad Street, Concourse Level, Corporate Trust Window, New
York, New York 10006. Principal of and premium, if any, and interest on the
Senior Securities will be payable at the office or agency in Boston,
Massachusetts of State Street Bank and Trust Company, as Paying Agent, provided
that, at the option of XTRA, Inc., payment of interest may be made by check
mailed to the address of the Person entitled thereto as it appears in the
Security Register. (Sections 3.1, 3.5 and 10.2) The offices or agencies of XTRA,
Inc. at which exchanges and transfers of Subordinated Securities will be
registrable and the office or agency of any Paying Agent with respect to the
Subordinated Securities will be identified in the Prospectus Supplement relating
thereto.
 
    Unless otherwise indicated in the Prospectus Supplement relating thereto,
the Debt Securities will be issued only in registered form, without coupons, in
denominations of $1,000 or any integral multiple thereof. (Section 3.2) No
service charge will be made for any transfer or exchange of the Debt Securities,
but XTRA, Inc. may require payment of a sum sufficient to cover any tax or other
governmental charge in connection therewith. (Section 3.5) The Indentures also
provide that the Debt Securities of any series, if so specified with respect to
a particular series, may be issued in permanent global form. See "Global
Securities."
 
    Debt Securities may be issued at a discount from their stated principal
amount. United States Federal income tax considerations and other special
considerations applicable to any such Original Issue Discount Securities will be
described in the applicable Prospectus Supplement. "Original Issue Discount
Security" means any security which provides for an amount less than the stated
principal amount thereof to be due and payable upon the declaration of
acceleration of the maturity thereof upon the occurrence and continuance of an
Event of Default. (Section 1.1)
 
                                       7
<PAGE>
    If the purchase price of any of the Debt Securities is denominated in a
foreign currency or currencies or a foreign currency unit or units or if the
principal of and any premium and interest on any series of Debt Securities is
payable in a foreign currency or currencies or a foreign currency unit or units,
the restrictions, elections, general tax considerations, specific terms and
other information with respect to such issue of Debt Securities and such foreign
currency or currencies or foreign currency unit or units will be set forth in
the applicable Prospectus Supplement. If any index is used to determine the
amount of payments of principal of, premium, if any, or interest on any series
of Debt Securities, special Federal income tax, accounting and other
considerations applicable thereto will be described in the applicable Prospectus
Supplement.
 
    Other than as set forth under "Certain Covenants of XTRA, Inc. and the
Guarantor," and only to the extent applicable to the Debt Securities of a
particular series, as indicated in the applicable Prospectus Supplement, there
are no provisions of the Indentures that afford Holders of the Debt Securities
protection in the event of a highly leveraged transaction involving XTRA, Inc.
or the Guarantor.
 
SUBORDINATION OF SUBORDINATED SECURITIES
 
    The indebtedness evidenced by the Subordinated Securities will be
subordinated and junior in right of payment to the extent set forth in the
Subordinated Indenture to the prior payment in full of amounts then due on all
Senior Indebtedness (as defined below). No payment shall be made on the
Subordinated Securities, including by way of redemption, purchase, or in any
other manner, if the Subordinated Trustee shall have received notice from XTRA,
Inc., the Guarantor or any Senior Lender (as defined below), that (i) there
exists a default which shall be continuing in the payment of principal of, or
premium, if any, or interest on any Senior Indebtedness, beyond any applicable
grace period with respect thereto, or (ii) there exists a default (other than a
default specified in clause (i) above) with respect to any Senior Indebtedness
which shall be continuing; provided, however, that no notice given with respect
to one or more defaults of the type specified in clause (ii) shall suspend for
longer than 180 days from the date of such notice any payment on Subordinated
Securities that has become due, and only one such notice may be given during any
360-day period.
 
    Upon any distribution of assets of XTRA, Inc. upon any liquidation,
dissolution or other winding-up of XTRA, Inc., whether voluntary or involuntary,
or in bankruptcy or insolvency, all principal of, premium, if any, and interest
due upon all Senior Indebtedness must be paid in full before the Holders of the
Subordinated Securities or the Subordinated Trustee are entitled to receive or
retain any assets so distributed in respect of the Subordinated Securities. By
reason of this provision, in the event of insolvency, Holders of the
Subordinated Securities may recover less, ratably, than other creditors of XTRA,
Inc., including holders of Senior Indebtedness.
 
    Subject to payment in full of all Senior Indebtedness of XTRA, Inc., the
rights of Holders of the Subordinated Securities will be subrogated to the
rights of holders of Senior Indebtedness to receive payments or distributions of
cash, property or securities of XTRA, Inc. applicable to Senior Indebtedness.
 
    "Senior Indebtedness" means the principal of, premium, if any, and interest
on (a) all indebtedness of XTRA, Inc. (including indebtedness of others
guaranteed by XTRA, Inc.), other than the Subordinated Securities, which is (i)
for money borrowed or (ii) evidenced by a note or similar instrument given in
connection with the acquisition of any business, properties or assets of any
kind or in connection with the obtaining of financing, and (b) amendments,
renewals, extensions, modifications and refundings of any such indebtedness or
obligation, in any such case whether outstanding on the date of the Subordinated
Indenture or thereafter created, incurred or assumed, unless in any case in the
instrument creating or evidencing any such indebtedness or obligation or
pursuant to which the same is outstanding it is provided that such indebtedness
or obligation is not superior in right of payment to the Subordinated Securities
or it is provided that such indebtedness or obligation is subordinated to Senior
Indebtedness
 
                                       8
<PAGE>
to substantially the same extent as the Subordinated Securities are subordinated
to Senior Indebtedness. The term "Senior Lender" shall mean any holder of Senior
Indebtedness or Senior Guarantor Indebtedness (as defined below under
"Guarantees").
 
    The Subordinated Indenture places no limitation on the amount of additional
Senior Indebtedness or Senior Guarantor Indebtedness that may be incurred by
XTRA, Inc. or the Company, respectively. XTRA, Inc. and the Company expect from
time to time to incur additional indebtedness constituting Senior Indebtedness
and Senior Guarantor Indebtedness. As of December 31, 1996, the amount of Senior
Indebtedness was approximately $822,000,000 and the amount of Senior Guarantor
Indebtedness was approximately $822,000,000.
 
GUARANTEES
 
    The Company will unconditionally guarantee the due and punctual payment of
principal of, premium, if any, and interest on the Debt Securities, when and as
the same shall become due and payable, whether at the maturity date, by
declaration of acceleration, call for redemption or otherwise, except that
payments under the Guarantees of the Subordinated Securities will be
subordinated to Senior Guarantor Indebtedness to the extent described below. The
term "Senior Guarantor Indebtedness" means all obligations of the Company under
guarantees of Senior Indebtedness of XTRA, Inc. No payment will be made by the
Guarantor under the Guarantees in respect of the Subordinated Securities during
any period that payments by XTRA, Inc. on the Subordinated Securities are
suspended by the subordination provisions of the Subordinated Indenture as
described above under "Subordination of Subordinated Securities." The Guarantees
will remain in effect until the entire principal of, premium, if any, and
interest on the Debt Securities shall have been paid in full or otherwise
discharged in accordance with the provisions of the Indentures. (Section 2.2)
 
    Upon any distribution of assets of the Company upon any liquidation,
dissolution or other winding up of the Company, whether voluntary or
involuntary, or in bankruptcy or insolvency, all amounts due in respect of all
Senior Guarantor Indebtedness must be paid in full before the Holders of the
Guarantees of the Subordinated Securities, or the Subordinated Trustee, are
entitled to receive or retain any assets so distributed in respect of the
Guarantees of the Subordinated Securities. By reason of this provision, in the
event of insolvency, Holders of the Subordinated Securities and the related
Guarantees may recover less, ratably, than other creditors of the Company,
including holders of Senior Guarantor Indebtedness.
 
    Subject to payment in full of all Senior Guarantor Indebtedness, the rights
of the Holders of the Subordinated Securities under the related Guarantees will
be subrogated to the rights of Holders of Senior Guarantor Indebtedness to
receive payments or distributions of cash, property or securities of the Company
applicable to Senior Guarantor Indebtedness.
 
    The Company's sources of funds for payment of its obligations, including its
obligations under the Guarantees of the Debt Securities, are advances and
dividends from its subsidiary, XTRA, Inc. See "Description of Common Stock of
XTRA Corporation--Holding Company Status."
 
GLOBAL SECURITIES
 
    Some or all of the Debt Securities of any series may be represented, in
whole or in part, by one or more Global Securities which will have an aggregate
principal amount equal to that of the Debt Securities represented thereby. Each
Global Security will be registered in the name of a Depositary or a nominee
thereof identified in the applicable Prospectus Supplement, will be deposited
with such Depositary or nominee or a custodian therefor and will bear a legend
regarding the restrictions on exchanges and registration of transfer thereof
referred to below and any such other matters as may be provided for pursuant to
the Indenture.
 
                                       9
<PAGE>
    No Global Security may be exchanged in whole or in part for Debt Securities
registered, and no transfer of a Global Security in whole or in part may be
registered, in the names of Persons other than the Depositary for such Global
Security or its nominee unless (i) such Depositary notifies XTRA, Inc. that it
is unwilling or unable to continue as Depositary for such Global Security or if
at any time such Depositary ceases to be a clearing agency registered under the
Exchange Act, (ii) there shall have occurred and be continuing an Event of
Default with respect to the Debt Securities, (iii) XTRA, Inc. executes and
delivers to the Trustee an order to the effect that the Global Securities shall
be transferable and exchangeable, or (iv) there shall exist such circumstances
in addition to, or in lieu of, the foregoing as may be described in the
applicable Prospectus Supplement. (Sections 3.1 and 3.5) Principal of, premium,
if any, and interest on a Global Security will be payable in the manner
described in the Prospectus Supplement relating thereto. The specific terms of
the depositary arrangements with respect to any portion of a series of Debt
Securities to be represented by a Global Security will be described in the
applicable Prospectus Supplement.

Subordinated Securities, whether or not such payment is prohibited by the
subordination provisions of the Subordinated Indenture; (b) failure to pay
principal of any Debt Security of that series when due, in the case of the
Subordinated Securities, whether or not such payment is prohibited by the
subordination provisions of the Subordinated Indenture; (c) default in the
deposit of any sinking
 
                                       12

fund payment, when due by the terms of the Debt Securities of that series, in
the case of the Subordinated Securities, whether or not such payment is
prohibited by the subordination provisions of the Subordinated Indenture; (d)
failure to perform any other covenant or breach of a warranty of XTRA, Inc. or
the Company in the applicable Indenture (other than a covenant expressly
included in such Indenture solely for the benefit of a series of Debt Securities
other than that series), continued for 60 days after written notice as provided
in the respective Indentures; (e) default by the Company or XTRA, Inc. with
respect to payment of other Indebtedness at its stated maturity or such as would
permit the holder thereof to accelerate the stated maturity of such
Indebtedness, in each case, in a principal amount of $10,000,000 or more if such
Indebtedness is not discharged or such acceleration is not rescinded or annulled
within 10 days after written notice as provided in the Indentures; (f) certain
events in bankruptcy, insolvency or reorganization of the Company or XTRA, Inc.;
and (g) any other Event of Default provided with respect to Debt Securities of
that series. (Section 5.1) If an Event of Default with respect to Debt
Securities of any series at the time outstanding shall occur and be continuing,
either the applicable Trustee or the Holders of at least 25% in principal amount
of the Debt Securities of that series may declare the principal amount of all
Debt Securities of that series (or if any Debt Securities of such series are
Original Issue Discount Securities, such portion of the principal amount of such
Debt Securities as may be specified by the terms thereof) to be due and payable
immediately. However, at any time after a declaration of acceleration with
respect to Debt Securities of any series has been made, but before a judgment or
decree based on such acceleration has been obtained, the Holders of a majority
in principal amount of the Debt Securities of that series may, under certain
circumstances, rescind and annul such acceleration. (Section 5.2) For
information as to waiver of default, see "Modification and Waiver."
 
    The Indentures provide that, subject to the duty of the respective Trustees
thereunder during default to act with the required standard of care, such
Trustee will be under no obligation to exercise any of its rights or powers
under the respective Indentures at the request or direction of any of the
Holders of the Debt Securities unless they shall have offered to such Trustee
reasonable indemnity. (Section 6.3) Subject to such provisions for
indemnification of the Trustees, the Holders of a majority in principal amount
of the Debt Securities of any series affected will have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the applicable Trustee, or exercising any trust or power conferred on such
Trustee, with respect to the Debt Securities of such series. (Section 5.12)
 
    No Holder of a Debt Security of any series will have any right to institute
any proceeding with respect to the applicable Indenture, or for the appointment
of a receiver or a trustee, or for any other remedy thereunder, unless (i) such
Holder has previously given to the applicable Trustee written notice of a
continuing Event of Default with respect to the Debt Securities of that series,
(ii) the Holders of at least 25% in aggregate principal amount of the
Outstanding Debt Securities of that series have made written request, and such
Holder or Holders have offered reasonable indemnity, to such Trustee to
institute such proceeding as trustee, and (iii) such Trustee has failed to
institute such proceeding, and has not received from the Holders of a majority
in aggregate principal amount of the Outstanding Debt Securities of that series
a direction inconsistent with such request, within 60 days after such notice,
request and offer. (Section 5.7) However, such limitations do not apply to a
suit instituted by a Holder of a Debt Security for the enforcement of payment of
the principal of or any premium or interest on such Debt Security on or after
the applicable due date specified in such Debt Security. (Section 5.8)
 
    The Guarantor and XTRA, Inc. will each be required to furnish to the
Trustees annually a statement as to whether there is a default in the
performance or observance of certain covenants. (Section 10.9)
 
DEFEASANCE AND DISCHARGE
 
    If so indicated in the applicable Prospectus Supplement with respect to the
Debt Securities of a series, the Guarantor and XTRA, Inc., at their option, (i)
will be discharged from any and all obligations in respect of the Debt
Securities (and Guarantees) of such series (except for certain obligations to
register
 
                                       13
<PAGE>
the transfer or exchange of Debt Securities of such series, to replace stolen,
lost or mutilated Debt Securities of such series, to maintain paying agencies
and to hold monies for payment in trust), or (ii) will be released from their
obligations to comply with the covenants that are specified under "Certain
Covenants of XTRA, Inc. and the Guarantor" above and other covenants and
obligations specified in Section 13.3 of the applicable Indenture with respect
to the Debt Securities of such series, and the occurrence of an event described
in clause (d) under "Events of Default" above with respect to any defeased
covenant and clauses (e) and (g) of the "Events of Default" above shall no
longer be an Event of Default if, in either case, the Company and/or XTRA, Inc.
deposits with the applicable Trustee, in trust, money and/or U.S. Government
Obligations that, through the payment of interest and principal in respect
thereof in accordance with their terms will provide money in an amount
sufficient to pay the principal of and each instalment of interest on the Debt
Securities of such series, on the stated maturity of such payments in accordance
with the terms of the applicable Indenture and the Debt Securities of such
series. Money and/or U.S. Government Obligations so held in trust will not be
subject to the subordination provisions described under "Subordination of
Subordinated Securities." (Sections 13.2 and 13.3) Such a trust may be
established only if, among other things, (i) no Event of Default or event which
with the giving of notice of lapse of time, or both, would become an Event of
Default under the applicable Indenture shall have occurred and be continuing on
the date of such deposit, (ii) no Event of Default described under clause (f)
under "Events of Default" above or event which with the giving of notice or
lapse of time, or both, would become an Event of Default described under such
clause (f) shall have occurred and be continuing at any time during the period
ending on or prior to the 90th day following such date of deposit, and (iii)
XTRA, Inc. delivers to the applicable Trustee an opinion of counsel to the
effect that the Holders of the Debt Securities of such series will not recognize
gain or loss for federal income tax purposes as a result of such deposit,
defeasance and discharge and will be subject to federal income tax on the same
amount and in the same manner and at the same times, as would have been the case
if such deposit, defeasance and discharge had not occurred. (Section 13.4)
 
    In the event the Guarantor and XTRA, Inc. exercise their options to omit
compliance with certain covenants and Events of Default of the applicable
Indenture with respect to the Debt Securities of a series as described under
clause (ii) above and the Debt Securities of such series are declared due and
payable because of the occurrence of any undefeased Event of Default, the amount
of money and U.S. Government Obligations on deposit with the applicable Trustee
may not be sufficient to pay amounts due on the Debt Securities of such series
at the time of the acceleration resulting from such Event of Default. In such a
case, XTRA, Inc. and the Guarantor would remain liable for such payments.
 
MODIFICATION AND WAIVER
 
    Modifications and amendments of the respective Indentures may be made by the
Guarantor, XTRA, Inc. and the Trustee with the consent of the Holders of a
majority in principal amount of the Outstanding Debt Securities of each series
which are affected thereby and 66 2/3% in aggregate principal amount of the
Outstanding Debt Securities of all series affected thereby; provided, however,
that no such modification or amendment may, without the consent of each Holder
of such Debt Security affected thereby: (a) change the stated maturity of the
principal of, or any instalment of principal of or interest on, any such Debt
Security; (b) reduce the principal amount of or interest on any such Debt
Securities; (c) change the place or currency of payment of principal of or
interest on any such Debt Security; (d) impair the right to institute suit for
the enforcement of any payment on or with respect to any such Debt Security; (e)
reduce the amount payable upon acceleration of the Maturity of a Debt Security;
(f) in the case of the Subordinated Securities, modify the subordination
provisions in a manner adverse to the Holders of the Subordinated Securities and
the related Guarantees; (g) reduce the above stated percentage of Holders of
Debt Securities which is required for modification or amendment of the
applicable Indenture or for waiver of compliance with certain provisions of the
applicable Indenture or for waiver of certain defaults; or (h) change in any
adverse way the terms of the Guarantees with respect to the payment of the
principal of, premium, if any, and interest on the Debt Securities. (Section
9.2)
 
                                       14
<PAGE>
    The Holders of a majority in principal amount of the Outstanding Debt
Securities of each series and 66 2/3% in aggregate principal amount of the
Outstanding Debt Securities of all series affected thereby may on behalf of the
Holders of all Debt Securities of the series waive, insofar as the Debt
Securities of that series are concerned, compliance by the Guarantor and XTRA,
Inc. with certain restrictive provisions of the applicable Indenture. (Section
10.9) The Holders of a majority in principal amount of the Outstanding Debt
Securities of a series may on behalf of the Holders of all Debt Securities of
that series waive any past default under the applicable Indenture with respect
to that series of Debt Securities, except a default in the payment of the
principal of, premium, if any, or interest on any Debt Security of the series or
in respect of any provision which under the applicable Indenture cannot be
modified or amended without the consent of the Holder of each Debt Security of
that series affected. (Section 5.13)
 
    The Indentures provide that in determining whether the Holders of the
requisite principal amount of the Outstanding Debt Securities have given or
taken any direction, notice, consent, waiver or other action under the
applicable Indenture as of any date, (i) the principal amount of an Original
Issue Discount Security that will be deemed to be Outstanding will be the amount
of the principal thereof that would be due and payable as of such date upon
acceleration of the Maturity thereof to such date, (ii) if, as of such date, the
principal amount payable at the Stated Maturity of a Debt Security is not
determinable (for example, because it is based on an index), the principal
amount of such Debt Security deemed to be Outstanding as of such date will be an
amount determined in the manner prescribed for such Debt Security, and (iii) the
principal amount of a Debt Security denominated in one or more foreign
currencies or currency units that will be deemed to be Outstanding will be the
U.S. dollar equivalent, determined as of such date in the manner prescribed for
such Debt Security (or, in the case of a Debt Security described in clause (i)
or (ii) above, of the amount described in such clause). Certain Debt Securities,
including those for whose payment or redemption money has been deposited or set
aside in trust for the Holders and those that have been fully defeased pursuant
to Section 13.2, will not be deemed to be Outstanding. (Section 1.1)
 
    Except in certain limited circumstances, XTRA, Inc. will be entitled to set
any day as a record date for the purpose of determining the Holders of
Outstanding Debt Securities of any series entitled to give or take any
direction, notice, consent, waiver or other action under the applicable
Indenture, in the manner and subject to the limitations provided in the
applicable Indenture. In certain limited circumstances, the Trustee will be
entitled to set a record date for action by the Holders. If a record date is set
for any action to be taken by Holders of a particular series, such action may be
taken only by persons who are Holders of Outstanding Debt Securities of that
series on the record date. To be effective, such action must be taken by Holders
of the requisite principal amount of such Debt Securities within a specified
period following the record date. For any particular record date, this period
will be 180 days or such shorter period as may be specified by XTRA, Inc. (or
the Trustee, if it set the record date), and may be shortened or lengthened (but
not beyond 180 days) from time to time. (Section 1.4)
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
    Each of XTRA, Inc. and the Company, without the consent of any Holders of
Debt Securities, may consolidate or merge with or into, or transfer or lease its
assets substantially as an entirety to, any Person, and any other Person may
consolidate or merge with or into, or transfer or lease its assets substantially
as an entirety to, XTRA, Inc. or the Company, provided that (i) the Person (if
other than XTRA, Inc. or the Company) formed by such consolidation or into which
XTRA, Inc. or the Company is merged or which acquires or leases the assets of
XTRA, Inc. or the Company substantially as an entirety is a corporation,
partnership or trust organized and validly existing under the laws of any United
States jurisdiction and assumes XTRA, Inc.'s or the Company's obligations on the
Debt Securities or the Guarantees, as the case may be, and under the Indentures,
(ii) after giving effect to such transaction no Event of Default, and no event
which, after notice or lapse of time or both, would become an Event of Default,
shall have happened and be continuing, and (iii) certain other conditions are
met. (Article Eight)

(Section 6.13) The Trustees will be permitted to engage in certain other
transactions; however, if they acquire any conflicting interest and there is a
default under the Debt Securities, they must eliminate such conflict or resign.

               DESCRIPTION OF PREFERRED STOCK OF XTRA CORPORATION
 
    The following description of the terms of the Preferred Stock sets forth
certain general terms and provisions of the Preferred Stock to which any
Prospectus Supplement may relate. Certain other terms of any series of the
Preferred Stock offered by any Prospectus Supplement will be described in such
Prospectus Supplement. The description of certain provisions of the Preferred
Stock set forth below and in any Prospectus Supplement does not purport to be
complete and is subject to and qualified in its entirety by reference to the
Company's Restated Certificate of Incorporation and By-laws, including the
definitions therein of certain terms, and the certificate of designations (each
a "Certificate of Designations") relating to each series of the Preferred Stock
that will be filed with the Commission and incorporated by reference as an
exhibit to the Registration Statement of which this Prospectus is a part at or
prior to the time of the issuance of such series of the Preferred Stock. Copies
of the Restated Certificate of Incorporation and the By-laws are incorporated by
reference as exhibits to the Registration Statement of which this Prospectus is
part.
 
GENERAL
 
    Under the Company's Restated Certificate of Incorporation, the Company is
authorized to issue up to 3,000,000 shares of Preferred Stock, in one or more
series, with such designations, voting powers, preferences and relative
participating, optional or other special rights, and with such qualifications,
limitations or restrictions thereon, as may be stated or expressed in
resolutions providing for the creation and issuance thereof adopted by the Board
of Directors of the Company. Thus, without stockholder approval, the Board of
Directors could authorize the issuance of Preferred Stock with voting,
conversion and other rights that could dilute the voting power and other rights
of the holders of Common Stock. No Preferred Stock is currently outstanding.
 
    The Preferred Stock shall have the dividend, liquidation, redemption and
voting rights set forth below, unless otherwise provided in a Prospectus
Supplement relating to a particular series of the
 
                                       16
<PAGE>
Preferred Stock. Reference is made to the Prospectus Supplement relating to the
particular series of the Preferred Stock offered hereby for specific terms,
including: (i) the designation and stated value per share of such Preferred
Stock and the number of shares offered; (ii) the amount of liquidation
preference per share; (iii) the initial public offering price at which such
Preferred Stock will be issued; (iv) the dividend rate (or method of
calculation), the dates on which dividends shall be payable and the dates from
which dividends shall commence to cumulate, if any; (v) any redemption or
sinking fund provisions; (vi) any conversion rights; and (vii) any additional
voting, dividend, liquidation, redemption, sinking fund and other rights,
preferences, privileges, limitations and restrictions.
 
    The Preferred Stock will, when issued, be fully paid and nonassessable and
will have no preemptive rights. Unless otherwise provided in the applicable
Prospectus Supplement, each series of the Preferred Stock will rank on a parity
as to the payment of dividends and amounts upon dissolution, liquidation or
winding up of the Company. The rights of the holders of each series of the
Preferred Stock will be subordinate to those of the Company's general creditors.
 
DIVIDEND RIGHTS
 
    Holders of the Preferred Stock of each series will be entitled to receive,
when, as and if declared by the Board of Directors of the Company, out of funds
of the Company legally available therefor, cash dividends on such dates and at
such rates as are set forth in, or as are determined by the method described in,
the Prospectus Supplement relating to such series of the Preferred Stock. Such
rate may be fixed or variable or both. Each such dividend will be payable to the
holders of record as they appear on the stock books of the Company on such
record dates, fixed by the Board of Directors of the Company, as specified in
the Prospectus Supplement relating to such series of Preferred Stock.
 
    Such dividends may be cumulative or noncumulative, as provided in the
Prospectus Supplement relating to such series of Preferred Stock. If the Board
of Directors of the Company fails to declare a dividend payable on a dividend
payment date on any series of Preferred Stock for which dividends are
noncumulative, then the right to receive a dividend in respect of the dividend
period ending on such dividend payment date will be lost, and the Company will
have no obligation to pay the dividend accrued for such period, whether or not
dividends on such series are declared payable on any future dividend payment
dates. Dividends on the shares of each series of Preferred Stock for which
dividends are cumulative will accrue from the date on which the Company
initially issues shares of such series or such other dates as may be set forth
in the applicable Prospectus Supplement.
 
    Unless otherwise specified in the applicable Prospectus Supplement, so long
as the shares of any series of the Preferred Stock are outstanding, unless (i)
full dividends (including, if such Preferred Stock is cumulative, dividends for
prior dividend periods) have been paid or declared and set apart for payment on
all outstanding shares of the Preferred Stock of such series (other than Junior
Stock, as defined below) and (ii) the Company is not in default or in arrears
with respect to the mandatory or optional redemption or mandatory repurchase or
other mandatory retirement of, or with respect to any sinking or other analogous
fund for, any shares of Preferred Stock of such series (other than Junior
Stock), the Company may not declare any dividends on any shares of Common Stock
of the Company or any other stock of the Company ranking as to the payment of
dividends or amounts upon dissolution, liquidation or winding up of the Company
junior to such series of Preferred Stock (the Common Stock and any such other
stock being herein referred to as "Junior Stock"), or make any payment on
account of, or set apart money for, the purchase, redemption or other retirement
of, or for a sinking or other analogous fund for, any shares of Junior Stock or
make any distribution in respect thereof, whether in cash or property or in
obligations or stock of the Company, other than Junior Stock that is neither
convertible into, nor exchangeable or exercisable for, any securities of the
Company other than Junior Stock and other than as a result of the
reclassification of Junior Stock.
 
                                       17
<PAGE>
LIQUIDATION PREFERENCES
 
    Unless otherwise specified in the applicable Prospectus Supplement, in the
event of any liquidation, dissolution or winding up of the Company, whether
voluntary or involuntary, the holders of a series of Preferred Stock will be
entitled to receive out of the assets of the Company available for distribution
to stockholders, before any distribution of assets is made to the holders of
Junior Stock, the amount set forth in the Prospectus Supplement relating to such
series of the Preferred Stock. If, upon any voluntary or involuntary
liquidation, dissolution or winding up of the Company, the amounts payable with
respect to the Preferred Stock of any series and any other shares of preferred
stock of the Company (including any other series of the Preferred Stock) ranking
as to the payment of amounts upon the dissolution, liquidation or winding up of
the Company on a parity with such series of the Preferred Stock are not paid in
full, the holders of the Preferred Stock of such series and of such other shares
of preferred stock of the Company will share ratably in any such distribution of
assets of the Company in proportion to the full respective preferential amounts
to which they are entitled. After payment to the holders of the Preferred Stock
of each series of the full preferential amounts of the liquidating distribution
to which they are entitled, the holders of each such series of the Preferred
Stock will be entitled to no further participation in any distribution of assets
by the Company.
 
REDEMPTION
 
    A series of the Preferred Stock may be redeemable, in whole or from time to
time in part, at the option of the Company, and may be subject to mandatory
redemption pursuant to a sinking fund or otherwise, in each case upon terms, at
the times and at the redemption prices set forth in the Prospectus Supplement
relating to such series. Shares of the Preferred Stock redeemed by the Company
will be restored to the status of authorized but unissued shares of preferred
stock of the Company.
 
    In the event that fewer than all of the outstanding shares of a series of
the Preferred Stock are to be redeemed, whether by mandatory or optional
redemption, the number of shares to be redeemed will be determined by lot or pro
rata (subject to rounding to avoid fractional shares) as may be determined by
the Company or by any other method as may be determined by the Company in its
sole discretion to be equitable. From and after the redemption date (unless
default is made by the Company in providing for the payment of the redemption
price plus accumulated and unpaid dividends, if any) dividends will cease to
accumulate on the shares of the Preferred Stock called for redemption and all
rights of the holders thereof (except the right to receive the redemption price
plus accumulated and unpaid dividends, if any) will cease.
 
    Unless otherwise specified in the applicable Prospectus Supplement, so long
as any dividends on shares of any series of the Preferred Stock or any other
series of preferred stock of the Company ranking on a parity as to payment of
dividends and amounts upon the liquidation, dissolution or winding up of the
Company with such series of the Preferred Stock are in arrears, no shares of any
such series of the Preferred Stock or such other series of preferred stock of
the Company will be redeemed (whether by mandatory or optional redemption)
unless all such shares are simultaneously redeemed, and the Company will not
purchase or otherwise acquire any such shares; provided, however, that the
foregoing will not prevent the purchase or acquisition of such shares pursuant
to a purchase or exchange offer made on the same terms to holders of all such
shares outstanding.
 
CONVERSION RIGHTS
 
    The terms, if any, on which shares of Preferred Stock of any series may be
exchanged for or converted (mandatorily or otherwise) into shares of Common
Stock or another series of Preferred Stock will be set forth in the Prospectus
Supplement relating thereto.
 
                                       18
<PAGE>
VOTING RIGHTS
 
    Except as indicated in a Prospectus Supplement relating to a particular
series of the Preferred Stock, or except as required by applicable Delaware law
or in the Company's Restated Certificate of Incorporation or as described below,
the holders of the Preferred Stock will not be entitled to vote for any purpose.
Unless otherwise specified in the related Prospectus Supplement, if cumulative
accrued dividends on any Preferred Stock have not been paid in an aggregate
amount equal to or greater than six quarterly dividends on such shares, the
Board of Directors shall increase by two the number of directors (and if
necessary amend the By-laws therefor) and the holders of the Preferred Stock,
voting as a single class, will be entitled to elect such additional two
directors to the Board of Directors until all such dividends in default have
been paid in full.
 
TRANSFER AGENT AND REGISTRAR
 
    Unless otherwise indicated in a Prospectus Supplement relating thereto,
Boston EquiServe LLP will be the transfer agent, dividend and redemption price
disbursement agent and registrar for shares of each series of the Preferred
Stock. See "Description of Common Stock of XTRA Corporation--General."
 
                DESCRIPTION OF COMMON STOCK OF XTRA CORPORATION
 
    The following description of the terms of the Common Stock sets forth
certain general terms and provisions of the Common Stock to which any Prospectus
Supplement may relate. The description of certain provisions of the Common Stock
set forth below and in any Prospectus Supplement does not purport to be complete
and is subject to and qualified in its entirety by reference to the Company's
Restated Certificate of Incorporation and By-laws, including the definitions
therein of certain terms. Copies of the Restated Certificate of Incorporation
and the By-laws are incorporated by reference as exhibits to the Registration
Statement of which this Prospectus is part.
 
GENERAL
 
    The Company's Restated Certificate of Incorporation authorizes the issuance
of up to 30,000,000 shares of Common Stock, par value $.50 per share, of which
15,246,099 shares have been issued and were outstanding as of December 31, 1996.
The Common Stock of the Company is listed on the New York Stock Exchange and the
additional shares of Common Stock that may be offered hereby will be listed,
subject to notice of issuance, on such exchange.
 
    The Transfer Agent and Registrar for the Company's Common Stock is Boston
EquiServe LLP, Mail Stop 45-02-64, P.O. Box 644, Boston, Massachusetts
02102-0644. In New York City, the Common Stock may be presented for transfer at
the office of BancBoston Trust Company of New York, One Exchange Plaza, 3rd
Floor, 55 Broadway, New York, New York 10006.
 
    Each holder of Common Stock is entitled to one vote for each share held.
Holders of Common Stock do not have preemptive rights and are not entitled to
cumulative voting in the election of Directors. All outstanding shares of Common
Stock are, and the shares of Common Stock that may be offered hereby when issued
will be, fully paid and non-assessable. The Board of Directors is authorized to
issue from time to time all of the authorized but unissued shares of Common
Stock.
 
    In case of any liquidation, dissolution or winding up of the Company, the
holders of Common Stock are entitled to share pro rata in the distribution of
all assets of the Company remaining after the holders of any series of Preferred
Stock have been paid the preference designated for such shares.
 
    Subject to the senior rights of any Preferred Stock, the holders of Common
Stock are entitled to receive dividends when and as declared by the Board of
Directors and paid by the Company from funds legally available therefor. The
Company's source of funds for the payment of cash dividends is advances and
dividends from its subsidiary, XTRA, Inc. Several of the Company's loan
agreements contain
 
                                       19
<PAGE>
restrictions on the payment of cash dividends by the Company, including
limitations restricting dividends to a fixed amount plus consolidated net income
of the Company earned since a date specified in the relevant agreement. In
addition, such loan agreements restrict the payment of advances and dividends to
the Company from its subsidiary, XTRA, Inc.
 
CERTAIN OTHER PROVISIONS OF THE RESTATED CERTIFICATE OF INCORPORATION
 
    Delaware law permits a corporation to eliminate the personal liability of
its directors to the corporation or to any of its stockholders for monetary
damages for a breach of fiduciary duty as a director, except (i) for breach of
the director's duty of loyalty, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) for
certain unlawful dividends and stock repurchases or (iv) for any transaction
from which the director derived an improper personal benefit. The Company's
Restated Certificate of Incorporation provides that no director of the Company
will be personally liable to the Company or its stockholders for monetary
damages for any breach of his fiduciary duty as a director, except as provided
by Delaware law.
 
    As permitted by Delaware law, the Company's Restated Certificate of
Incorporation does not permit stockholder action by written consent. The
affirmative vote of the holders of at least 80% of the Company's then
outstanding Common Stock is required to amend, alter or repeal this provision.
 
    The Company's By-laws provide that stockholder nominations of candidates for
election as directors and other stockholder proposals generally must be received
by the Secretary of the Company not less than 60 nor more than 90 days prior to
the applicable stockholders' meeting.
 
    The Company is subject to the provisions of Section 203 of the General
Corporation Law of Delaware. In general, this statute prohibits a publicly-held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner. An "interested
stockholder" is a person who, together with affiliates and associates, owns (or
within the prior three years did own) 15% or more of the corporation's voting

    Because the Company is a holding company, the right of the Company to
participate in any distribution of assets of any subsidiary upon its liquidation
or reorganization (and thus the ability of the Company's stockholders to benefit
indirectly from such distribution) would be subject to the prior claims of
creditors of that subsidiary, except to the extent that the Company itself may
be a creditor of that subsidiary with recognized claims. In addition, XTRA, Inc.
conducts its leasing business primarily through fleet management agreements with
its subsidiaries, which accounted for 22% of XTRA, Inc.'s consolidated assets at
December 31, 1996 and for 95% of its consolidated revenues for fiscal 1996. The
right of XTRA, Inc. to participate in any distribution of assets of any
subsidiary upon its liquidation or reorganization (and thus the ability of the
Company's stockholders to benefit indirectly from such distribution) would be
subject to the prior claims of creditors of that subsidiary, except to the
extent that XTRA, Inc. itself may be a creditor of that subsidiary with
recognized claims. See, "The Company" for the right of XTRA, Inc. to terminate
the fleet management agreements.
 
                              PLAN OF DISTRIBUTION
 
    The Company and/or XTRA, Inc. may sell Securities to or through underwriters
or to dealers acting as principals for their own account and also may sell
Securities directly to other purchasers or through agents. The Company and XTRA,
Inc. reserve the right to sell Securities directly to investors on their own
behalf in those jurisdictions where they are authorized to do so.
 
                                       20
<PAGE>
    Underwriters may offer and sell the Securities at a fixed price or prices
that may be changed, at market prices prevailing at the time of sale, at prices
related to such prevailing market prices or at negotiated prices. The Company or
XTRA, Inc. also may, from time to time, authorize dealers, acting as the
Company's or XTRA, Inc.'s agents, as the case may be, to offer and sell the
Securities upon such terms and conditions as set forth in the related Prospectus
Supplement. In connection with the sale of the Securities, underwriters may
receive compensation from the Company or XTRA, Inc. in the form of underwriting
discounts or commissions and may also receive commissions from purchasers of the
Securities for whom they may act as agent. Underwriters may sell the Securities
to or through dealers, and such dealers may receive compensation in the form of
discounts, concessions or commissions from the underwriters and/or commissions
from the purchasers for whom they may act as agents.
 
    Any underwriting compensation paid by the Company or XTRA, Inc. to
underwriters or agents in connection with the offering of the Securities, and
any discounts, concessions or commissions allowed by underwriters to
participating dealers, will be set forth in the related Prospectus Supplement.
Dealers and agents participating in the distribution of the Securities may be
deemed to be underwriters, and any discounts and commissions received by them
and any profit realized by them on resale of the Securities may be deemed to be
underwriting discounts and commissions. Underwriters, dealers and agents may be
entitled, under agreements entered into with the Company and/or XTRA, Inc., to
indemnification against and contribution towards certain civil liabilities.
 
    If so indicated in a Prospectus Supplement, the Company and/or XTRA, Inc.
will authorize underwriters or other persons acting as the Company's and/or
XTRA, Inc.'s agents to solicit offers by certain institutions to purchase
Securities from the Company and/or XTRA, Inc. pursuant to contracts providing
for payment and delivery on a future date. Institutions with which such
contracts may be made include commercial and savings banks, insurance companies,
pension funds, investment companies, educational and charitable institutions and
others, but in all cases such institutions must be approved by the Company
and/or XTRA, Inc. The obligations of any purchaser under any such contract will
be subject to the condition that the purchase of the Securities shall not at the
time of delivery be prohibited under the laws of the jurisdiction to which such
purchaser is subject. The underwriters and such other agents will not have any
responsibility in respect of the validity or performance of such contracts.
 
    Any Securities issued hereunder (other than Common Stock) will be new issues
of securities with no established trading market. Neither the Company nor XTRA,
Inc. currently intends to apply for the listing of any Securities (other than
the Common Stock) on any national securities exchange. No assurance can be given
as to the liquidity of the trading market for any such Securities.
 
    Certain of the underwriters or agents and their associates may be customers
of, engage in transactions with and perform services for XTRA, Inc. or the
Company in the ordinary course of business.
 
                             VALIDITY OF SECURITIES
 
    The validity of the Securities offered hereby will be passed upon for XTRA,
Inc. and the Company by Ropes & Gray, One International Place, Boston,
Massachusetts 02110, and for any underwriter or agent by Sullivan & Cromwell,
125 Broad Street, New York, New York 10004.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    The General Corporation Law of the State of Delaware, in which XTRA
Corporation is incorporated, gives a corporation power to indemnify any of its
officers or directors against certain expenses, judgments, fines and amounts
paid in settlement in connection with certain actions, suits or proceedings,
provided generally, that such person acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. In addition, the statutes
of Delaware contain provisions to the general effect that any director shall in
the performance of his duties be fully protected in relying in good faith upon
the books of account or records of the corporation or statements prepared by any
official of the corporation.
 
    The Restated Certificate of Incorporation of XTRA Corporation includes the
following provision:
 
    This corporation shall, to the maximum extent permitted from time to time
under the law of the State of Delaware, indemnify and upon request shall advance
expenses to any person who is or was a party or is threatened to be made a party
to any threatened, pending or completed action, suit, proceeding or claim,
whether civil, criminal, administrative or investigative, by reason of the fact
that he is or was or has agreed to be a director or officer of this corporation
or while a director or officer is or was serving at the request of this
corporation as a director, officer, partner, trustee, employee or agent of any
corporation, partnership, joint venture, trust or other enterprise, including
service with respect to employee benefit plans, against expenses (including
attorney's fees and expenses), judgments, fines, penalties and amounts paid in
settlement incurred in connection with the investigation, preparation to defend
or defense of such action, suit, proceeding, or claim; provided, however, that
the foregoing shall not require this corporation to indemnify or advance
expenses to any person in connection with any action, suit, proceeding, claim or
counterclaim initiated by or on behalf of such person. Such indemnification
shall not be exclusive of other indemnification rights arising under any by-law,
agreement, vote of directors or stockholders or otherwise and shall inure to the
benefit of the heirs and legal representatives of such person. Any repeal or
modification of the foregoing provisions of this Article 9 shall not adversely
affect any right or protection of a director or officer of this corporation
existing at the time of such repeal or modification.
 
    The Business Corporation Act of the State of Maine, in which XTRA, Inc. is
incorporated, gives a corporation power to indemnify any of its officers or
directors against certain expenses, judgements, fines, and amounts paid in
settlement in connection with certain actions, suits or proceedings, provided
generally, that such person acted in good faith and in the reasonable belief
that his action was in the best
 
                                      II-1
<PAGE>
interests of the corporation, and with respect to any criminal action or
proceeding, had no reasonable cause to believe that his conduct was unlawful. In
addition, the statute provides that if a director or officer is successful in
the merits or otherwise in defense of certain actions, suits or proceedings
against him, while serving as a director or officer of the corporation, the
corporation shall indemnify him against expenses reasonably incurred in defense
of such claim, including attorney's fees.
 
    The By-laws of XTRA, Inc. include the following provision:
 
    The corporation shall indemnify any person who is or was a director,
officer, employee or agent of the corporation, or who is or was serving in
another capacity at the request of the corporation, to the extent authorized by
the Maine Business Corporation Act and may purchase and maintain insurance to
protect itself against liability for such indemnification.
 
    In addition, XTRA Corporation maintains a directors' and officers' liability
insurance policy.
 
    XTRA Corporation has entered into Indemnification Agreements, the form of
which was approved by the stockholders of XTRA Corporation, with certain
officers of XTRA Corporation and its subsidiaries, including XTRA, Inc. The
Indemnification Agreements provide a number of procedures, presumptions and
remedies used in the determination of the right of the officer to
indemnification. These procedures, presumptions and remedies substantially
broaden the indemnity rights of officers beyond that provided by XTRA
Corporation's Restated Certificate of Incorporation described above. If an
action against an indemnified party is dismissed with or without prejudice, the
defense is deemed to have been successful and the indemnification is required to
be made. The Indemnification Agreements provide that expenses must be paid
within twenty days of any request and that a determination of entitlement must
be made within sixty days of the indemnification request (otherwise a
determination in favor of the indemnified party is deemed to have been made). If
there is a change in control of XTRA Corporation (as defined in the
Indemnification Agreement), the indemnified party is presumed to be entitled to
indemnification (although XTRA Corporation may overcome this presumption), the
indemnified party may require that independent counsel make the determination of
entitlement and may choose such counsel, subject to objection by the Company on
limited grounds. If a determination of entitlement is made, XTRA Corporation is
bound, but if the indemnified party has previously been denied indemnification
pursuant to the terms of the Indemnification Agreement he or she is entitled to
seek a de novo determination from a court. XTRA Corporation is precluded from
challenging the validity of the procedures and presumptions contained in the
Indemnification Agreement in any court proceeding. The Indemnification Agreement
covers proceedings brought on or after the date of the execution of the
particular Indemnification Agreement, including proceedings based on acts prior
to the date of the particular agreement.

ITEM 17. UNDERTAKINGS.
 
    The undersigned registrants hereby undertake: (1) To file, during any period
in which offers or sales are being made, a post-effective amendment to this
registration statement:
 
        (i) To include any prospectus required by section 10(a)(3) of the
    Securities Act of 1933;
 
        (ii) To reflect in the prospectus any facts or events arising after the
    effective date of this registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the aggregate,
    represent a fundamental change in the information set forth in this
    registration statement;
 
        (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in this registration statement or any
    material change to such information in this registration statement;
    provided, however, that the undertakings set forth in paragraphs (i) and
    (ii) above do not apply if the information required to be included in a
    post-effective amendment by those paragraphs is contained in periodic
    reports filed by the registrants pursuant to section 13 or section 15(d) of
    the Securities Exchange Act of 1934 that are incorporated by reference in
    this registration statement.
 
    (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
    (4) That, for the purposes of determining any liability under the Securities
Act of 1933, each filing of the registrants' annual report pursuant to section
13(a) or section 15(d) of the Securities Exchange Act of 1934 that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    (5) To file an application for the purpose of determining the eligibility of
the Subordinated Trustee to act under Subsection (a) of Section 310 of the Trust
Indenture Act in accordance with the rules and regulations prescribed by the
Commission under Section 305(b)(2) of the Trust Indenture Act.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the provisions described in Item 15 above, or otherwise,
the Registrants have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrants of expenses incurred or paid by a director, officer, or controlling
person of the Registrants in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrants will, unless in
the opinion of their counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by them is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.

Dear Sirs:

          XTRA, Inc., a Maine corporation (the "Company"), proposes to issue 
and sell from time to time its Series C Medium-Term Notes, each of which 
shall have the benefit of an unconditional guarantee (the "Guarantee") of 
payment of principal, premium, if any, and interest from XTRA Corporation, a 
Delaware corporation ("XTRA" or the "Guarantor") (the Guarantee, together 
with the Series C Medium-Term Notes, the "Securities"), in an aggregate 
principal amount up to $604,000,000 and agrees with each of you (individually 
an "Agent" and collectively the "Agents") as set forth in this Agreement.

<PAGE>

          Subject to the terms and conditions stated herein and to the 
reservation by the Company of the right to sell Securities directly on its 
own behalf as provided in Section 2(a) hereof, the Company and XTRA hereby 
(i) appoint each Agent as an agent of the Company and XTRA for the purpose of 
soliciting and receiving offers to purchase Securities from the Company and 
XTRA pursuant to Section 2(a) hereof and (ii) agree that, except as otherwise 
contemplated herein, whenever they determine to sell Securities directly to 
any Agent as principal, they will enter into a separate agreement (each a 
"Terms Agreement"), substantially in the form of Annex I hereto, relating to 
such sale in accordance with Section 2(b) hereof.

          The Securities will be issued under an indenture, dated as of 
August 15, 1994 (the "Original Indenture"), between the Company, XTRA and The 
First National Bank of Boston, as Trustee (the "Bank of Boston"), as amended 
and supplemented by (i) the First Supplemental Indenture, dated as of 
September 30, 1994 (the "First Supplemental Indenture"), between the Company, 
XTRA, XTRA Missouri, Inc., a Delaware corporation ("XTRA Missouri"), and the 
Bank of Boston, as Trustee, and (ii) the Second Supplemental Indenture, dated 
as of ______ __, 1997 (the "Second Supplemental Indenture" and together with 
the Original Indenture and the First Supplemental Indenture, the 
"Indenture"), between the Company, XTRA and State Street Bank and Trust 
Company, as Trustee. On October 2, 1995, State Street Bank and Trust Company 
(the "Trustee") succeeded to all or substantially all of the corporate trust 
business of the Bank of Boston, thereby becoming the successor Trustee 
pursuant to the terms of the Indenture. The Securities shall have the 
maturity ranges, annual interest rates, if any, redemption provisions and 
other terms set forth in the Prospectus referred to below as it may be 
amended or supplemented from time to time. The Securities will be issued, and 
the terms and rights thereof established, from time to time by the Company 
and the XTRA in accordance with the Indenture and the Administrative 
Procedure attached hereto as Annex II as it may be amended from time to time 
by written agreement between the Agents and the Company and XTRA (the 
"Procedure") and, if applicable, will be specified in a related Terms 
Agreement.

          1.  The Company and XTRA represent and warrant to, and agree with, 
each Agent that:

          (a)  A registration statement on Form S-3 (Registration No. 
33-65293) has been filed with the Securities and Exchange Commission (the 
"Commission"); such registration statement and any post-effective amendments 
thereto, each in the form heretofore delivered or to be delivered to such 
Agent, excluding exhibits to such registration statement but including all 
documents incorporated by reference in the prospectus included in such 
registration statement, have been declared effective by the Commission in 
such form; no other document with respect to such registration statement or 
document incorporated by reference therein has heretofore been filed or 
transmitted for filing with the Commission (other than the prospectuses filed 
pursuant to Rule 424(b) of the rules and regulations of the Commission under 
the Securities Act of 1933, as amended (the "Act"), each in the form 
heretofore delivered to the Agents); and no stop order suspending the 
effectiveness of such registration statement has been issued and no 
proceeding for that purpose has been initiated or threatened by the 
Commission (any preliminary prospectus included such registration statement 
or filed with the Commission pursuant to Rule 424(a) of the rules and 
regulations of the Commission under the Act, being

                                    -2-

<PAGE>

hereinafter called a "Preliminary Prospectus"; the various parts of such 
registration statement, including all exhibits thereto and the documents 
incorporated by reference in the prospectus contained in such registration 
statement at the time such part of such  registration statement became 
effective but excluding Form T-1 and, if applicable, including the 
information contained in the form of final prospectus filed with the 
Commission pursuant to Rule 424(b) under the Act, each as amended at the time 
such part of such registration  statement became effective, being hereinafter 
collectively called the "Registration Statement"; the prospectus (including, 
if applicable, any prospectus supplement) relating to the Securities, in the 
form in which it has most recently been filed, or transmitted for filing, 
with the Commission on or prior to the date of this Agreement, being 
hereinafter called the "Prospectus"; any reference herein to any Preliminary 
Prospectus or the Prospectus, including any supplement to the Prospectus that 
sets forth only the terms of a particular issue of the Securities (a "Pricing 
Supplement"), shall be deemed to refer to and include the documents 
incorporated by reference therein pursuant to the applicable form under the 
Act, as of the date of such Preliminary Prospectus or Prospectus, as the case 
may be; any reference to any amendment or supplement to any Preliminary 
Prospectus or the Prospectus shall be deemed to refer to and include any 
documents filed after the date of such Preliminary Prospectus or Prospectus, 
as the case may be, under the Securities Exchange Act of 1934, as amended 
(the "Exchange Act"), and incorporated therein by reference; any reference to 
any amendment to the Registration Statement shall be deemed to refer to and 
include any annual report of the Company filed pursuant to Section 13(a) or 
15(d) of the Exchange Act after the effective date of the Registration 
Statement that is incorporated by reference in the Registration Statement; 
and any reference to the Prospectus as amended or supplemented shall be 
deemed to refer to and include the Prospectus as amended or supplemented 
(including by the applicable Pricing Supplement filed in accordance with 
Section 4(a) hereof) in relation to Securities sold pursuant to this 
Agreement, in the form in which it is filed with the Commission pursuant to 
Rule 424(b) under the Act and in accordance with Section 4(a) hereof, 
including any documents incorporated by reference therein as of the date of 
such filing);

          (b)  The documents incorporated by reference in the Prospectus, 
when they became effective or were filed with the Commission, as the case may 
be, conformed in all material respects to the requirements of the Act or the 
Exchange Act, as applicable, and the rules and regulations of the Commission 
thereunder, and none of such documents contained an untrue statement of a 
material fact or omitted to state a material fact required to be stated 
therein or necessary to make the statements therein not misleading; and any 
further documents so filed and incorporated by reference in the Prospectus 
when such documents become effective or are filed with the Commission, as the 
case may be, will conform in all material respects to the requirements of the 
Act or the Exchange Act, as applicable, and the rules and regulations of the 
Commission thereunder and will not contain an untrue statement of a material 
fact or omit to state a material fact required to be stated therein or 
necessary to make the statements therein not misleading; provided, however, 
that this representation and warranty shall not  apply to any statements or 
omissions made in reliance upon and in conformity with information furnished 
in writing 

                                    -3-

<PAGE>

to XTRA and the Company by any Agent expressly for use in the Prospectus as 
amended or supplemented to relate to a particular issuance of Securities;

          (c)  The Registration Statement and the Prospectus conform, and any 
further amendments or supplements to the Registration Statement or the 
Prospectus will conform, in all material respects to the requirements of the 
Act and the Trust Indenture Act of 1939, as amended (the "Trust Indenture 
Act"), and the rules and regulations of the Commission thereunder and do not 
and will not, as of the applicable effective date as to the Registration 
Statement and any amendment thereto and as of the applicable filing date as 
to the Prospectus and any amendment or supplement thereto, contain an untrue 
statement of a material fact or omit to state a material fact required to be 
stated therein or necessary to make the statements therein not misleading; 
provided, however, that this representation and warranty shall not apply to 
any statements or omissions made in reliance upon and in conformity with 
information furnished in writing to XTRA and the Company by any Agent 
expressly for use in the Prospectus as amended or supplemented to relate to a 
particular issuance of Securities;

          (d)  None of XTRA, the Company, or any of their subsidiaries has 
sustained since the date of the latest audited financial statements included 
or incorporated by reference in the Prospectus any material loss or 
interference with its business from fire, explosion, flood or other calamity, 
whether or not covered by insurance, or from any labor dispute or court or 
governmental action, order or decree, otherwise than as set forth or 
contemplated in the Prospectus; and, since the respective dates as of which 
information is given in the Registration Statement and the Prospectus, except 
as otherwise disclosed therein there has not been any change in the capital 
stock (other than issuances of capital stock pursuant to the provisions of 
employee or director benefit or stock option plans or agreements of XTRA) or 
any increase in excess of $50 million in the consolidated long-term debt of 
XTRA or the Company or any material adverse change, or any development 
involving a prospective material adverse change, in or affecting the general 
affairs, management, financial position, stockholders' equity or results of 
operations of XTRA or the Company and their respective subsidiaries, 
otherwise than as set forth or contemplated in the Prospectus;

          (e)   XTRA and the Company and their respective subsidiaries have 
good and marketable title to all personal property owned by any of them, in 
each case  free and clear of all liens, encumbrances and defects except such 
as are described or referred to in the Prospectus or such as do not 
materially affect the value of such property and do not interfere with the 
use made and proposed to be made of such property by the Company or XTRA and 
their respective subsidiaries; and any real property and buildings held under 
lease by XTRA or the Company and their respective subsidiaries are held by 
them under valid, subsisting and enforceable leases with such exceptions as 
are not material and do not interfere with the use made and proposed to be 
made of such property by XTRA, the Company and their respective subsidiaries;

          (f) XTRA has been duly incorporated and is validly existing as a 
corporation in good standing under the laws of the State of Delaware and the

<PAGE>

incorporated and is validly existing as a corporation in good standing under 
the laws of the State of Maine, in each case, with power and authority 
(corporate and other) to own its properties and conduct its business as 
described in the Prospectus, and none of them is required to be qualified as 
a foreign corporation for the transaction of business under the laws of any 
jurisdictions in which the consequences of a failure to qualify, individually 
or in the aggregate, would have a material adverse effect on the business of 
XTRA, the Company and their respective subsidiaries (taken as a whole); and 
each subsidiary of XTRA and the Company has been duly incorporated and is 
validly existing as a corporation in good standing under the laws of its 
jurisdiction of incorporation and has been duly qualified as a foreign 
corporation for the transaction of business and is in good standing under the 
laws of each other jurisdiction in which it owns or leases properties, or 
conducts any business, so as to require such qualification and in which the 
consequences of a failure to so qualify would have a material adverse effect 
on the business of XTRA, the Company and their respective subsidiaries (taken 
as a whole);

          (g)  XTRA and the Company each has an authorized capitalization as 
set forth for it in the Prospectus, and all of the issued and outstanding 
shares of capital stock of XTRA have been duly and validly authorized and 
issued and are fully paid and non-assessable; all of the issued shares of 
capital stock of the Company and of each other direct and indirect subsidiary 
of XTRA have been duly and validly authorized and issued, are fully paid and 
nonassessable and (except for directors' qualifying shares and except as set 
forth in the Prospectus) are owned directly by XTRA or indirectly through one 
or more of its subsidiaries, free and clear of all liens, encumbrances, 
equities or claims; 

          (h)  The Securities have been duly authorized, and, when issued and 
delivered pursuant to the Indenture and this Agreement and any Terms 
Agreement, will have been duly executed, authenticated, issued and delivered 
and will constitute valid and legally binding obligations of the Company 
entitled to the benefits provided by the Indenture enforceable in accordance 
with their terms, subject, as to enforcement, to bankruptcy, insolvency, 
reorganization and other laws of general applicability relating to or 
affecting creditors' rights and to general equity principles; the Indenture 
has been duly authorized and duly qualified under the Trust Indenture Act and 
constitutes a valid and legally binding instrument, enforceable in accordance 
with its terms, subject, as to enforcement, to bankruptcy, insolvency, 
reorganization and other laws of general applicability relating to or 
affecting creditors' rights and to general equity principles; and the 
Indenture (including the form of the Guarantee) conforms and the Securities 
of any particular issuance of Securities will conform to the descriptions 
thereof contained in the Prospectus as amended or supplemented to relate to 
such issuance of Securities;

          (i)  The issue and sale of the Securities, the compliance by XTRA 
and the Company with, as applicable, all of the provisions of the Securities, 
the Indenture, the Guarantee, this Agreement and any Terms Agreement, and the 
consummation of the transactions herein and therein contemplated will not 
conflict with or result in (x) a breach or violation of any of the terms or 
provisions of, or constitute a default under, any indenture, mortgage, deed 
of trust, loan agreement or other agreement or instrument to which XTRA or 
any of its 

                                    -5-

<PAGE>

subsidiaries, including the Company, is a party or by which XTRA or any of 
its subsidiaries, including the Company, is bound, nor (y) will such action 
result in any breach or violation of the terms or provisions of XTRA's 
Certificate of Incorporation, as amended, the Company's Articles of 
Incorporation, as amended, XTRA's or the Company's By-Laws or any statute or 
any order, rule or regulation of any court or governmental agency or body 
having jurisdiction over XTRA or any of its subsidiaries, including the 
Company, or any of their properties, in each case in provision (x) above the 
consequences of which would in any way affect the issuance and sale of the 
Securities, the performance of the Guarantee, the performance of this 
Agreement or the transactions contemplated hereby or the performance of the 
provisions of the Indenture, or otherwise have, individually or in the 
aggregate, a material adverse effect on the business of XTRA and its 
subsidiaries, including the Company (taken as a whole); and no consent, 
approval, authorization, order, registration or qualification of or with any 
court or governmental agency or body is required for the solicitation of 
offers to purchase Securities and the issue and sale of the Securities, the 
consummation by XTRA or the Company of the other transactions contemplated by 
this Agreement, any Terms Agreement, the Indenture or the Guarantee, except 
such as have been, or will have been prior to the Commencement Date (as 
defined in Section 3 hereof), obtained under the Act or the Trust Indenture 
Act and such consents, approvals, authorizations, registrations or 
qualifications as may be required under state securities or Blue Sky laws in 
connection with the solicitation by the Agents of offers to purchase 
Securities from the Company and XTRA and with purchases of Securities by the 
Agents as principal, as the case may be, in each case in the manner 
contemplated hereby;

          (j)  There are no legal or governmental proceedings pending to 
which XTRA or any of its subsidiaries, including the Company, is a party or 
to which any property of XTRA or any of its subsidiaries, including the 
Company, is subject (other than as set forth or contemplated in the 
Prospectus and other than litigation incident to the kind of business 
conducted by XTRA and its subsidiaries, including the Company), which, if 
determined adversely to XTRA or its subsidiaries, including the Company, 
would individually or in the aggregate have a material adverse effect on the 
consolidated financial position, stockholders' equity or annual results of 
operations of XTRA and its subsidiaries, including the Company (taken as a 
whole); and, to the best of XTRA's knowledge, no such proceedings are 
threatened or contemplated by governmental authorities or threatened by 
others;

          (k)  The accountants who have certified the financial statements of 
XTRA and its subsidiaries, including the Company, included in the 
Registration Statement are independent public accountants as required by the 
Act and the rules and regulations of the Commission thereunder; and

          (l)  Immediately after the settlement of any sale of Securities by 
the Company and XTRA resulting from solicitation by the Agents hereunder and 
immediately after any Time of Delivery, as defined in Section 2(b), relating 
to a sale under a Terms Agreement, the aggregate amount of Securities which 
shall have been issued 

                                    -6-

<PAGE>

and sold by the Company and XTRA hereunder or under any Terms Agreement and 
of any debt securities of the Company or guarantees of XTRA (other than such 
Securities) that shall have been issued and sold pursuant to the Registration 
Statement will not exceed the amount of debt securities or guarantees, as the 
case may be, registered under the Registration Statement.

          2.  (a)  On the basis of the representations and warranties herein 
contained, and subject to the terms and conditions herein set forth, each of 
the Agents hereby severally and not jointly agrees, as agent of the Company 
and XTRA, to use its reasonable efforts when requested by the Company and 
XTRA to solicit and receive offers to purchase the Securities from the 
Company upon the terms and conditions set forth in the Prospectus as amended 
or supplemented from time to time. So long as this Agreement shall remain in 
effect, neither the Company nor XTRA shall, without the consent of the 
Agents, solicit or accept offers to purchase, or sell or guarantee, any debt 
securities with a maturity at the time of original issuance greater than or 
equal to 9 months and less than or equal to 30 years, except as contemplated 
hereby or in any Terms Agreement. XTRA and the Company may, subject to 
Section 1(d), enter into any revolving credit and/or term loan agreements 
with commercial banking institutions and loans from insurance companies 
(provided that such loans shall not consist of Securities). The Company 
reserves the right to sell, and may solicit and accept offers to purchase, 
Securities directly on its own behalf; provided, however, that if at the time 
of any such sales the Agents are posting terms and conditions for the 
purchase and sale of the Securities, such sales shall be on substantially the 
same terms and conditions as then posted by the Agents; provided further, 
that in the case of any such sales not resulting from a solicitation made by 
any Agent, no commission shall be payable with respect to such sales. Each 
Agent also acknowledges and agrees that the Company may accept (but not 
solicit) offers to purchase Securities through additional agents, and may 
appoint another agent, or agents, to solicit offers to purchase the Notes, 
provided that such additional agent or agents shall be engaged on terms 
substantially similar to the applicable terms of this Agreement (except that 
commissions payable to such agent or agents shall be identical to those set 
forth in the commission schedule in this Section 2(a)).

          The Company and XTRA reserve the right, in their sole discretion, 
to instruct the Agents to suspend at any time, for any period of time or 
permanently, the solicitation of offers to purchase the Securities. As soon 
as practicable, but in any event not later than one business day in New York 
City after receipt of notice from the Company and XTRA, the Agents will 
suspend solicitation of offers to purchase Securities from the Company and 
XTRA until such time as the Company and XTRA have advised the Agents that 
such solicitation may be resumed.

          The Company agrees to pay each Agent a commission, at the time of 
settlement of any sale of a Security by the Company and XTRA as a result of a 
solicitation made by such Agent, in an amount equal to the following 
applicable percentage of the principal amount of such Security sold:

For purposes of the foregoing, the "Investment Grade" commission schedule 
applies if the Notes are rated BBB- or better by Standard & Poor's 
Corporation and Baa3 or better by Moody's Investors Corporation; the "Split 
Rated" commission schedule applies if the Notes are so rated by one, but not 
both, of such rating agencies.

          Each of the Agents is authorized to solicit offers to purchase the 
Securities only in denominations of $100,000 or any amount in excess thereof 
that is an integral multiple of $1,000 at a purchase price equal to 100% of 
their principal amount. Each Agent shall communicate to the Company, orally 
or in writing, each reasonable offer to purchase Securities received by it as 
Agent other than those rejected by such Agent. The Company shall have the 
sole right to accept offers to purchase Securities and may reject any 
proposed purchase of Securities as a whole or in part. Each Agent shall have 
the right, in its discretion reasonably exercised, to reject any offer 
received by it to purchase Securities, as a whole or in part, and any such 
rejection by it shall not be deemed a breach of its agreements contained 
herein.

          (b)  Each sale of Securities to any Agent as principal shall be 
made in accordance with the terms of this Agreement and (unless the Company 
and such Agent shall otherwise agree) a Terms Agreement which will provide 
for the sale of such Securities to, and the purchase thereof by, such Agent. 
A Terms Agreement may also specify certain provisions relating to the 
reoffering of such Securities by such Agent. The commitment of any Agent to 
purchase 

                                    -8-

<PAGE>

Securities pursuant to any Terms Agreement shall be deemed to have been made 
on the basis of the representations and warranties of the Company and XTRA 
herein contained and shall be subject to the terms and conditions herein set 
forth. Each Terms Agreement shall specify the principal amount of Securities 
to be purchased by any Agent pursuant thereto, the price to be paid to the 
Company for such Securities, any provisions relating to rights of, and 
default by, underwriters acting together with such Agent in the reoffering of 
the Securities and the time and date and place of delivery of and payment for 
such Securities. Such Terms Agreement shall also specify any requirements for 
opinions of counsel, accountants' letters and officers' certificates pursuant 
to Section 4 hereof.

          For each sale of Securities to an Agent as principal that is not 
made pursuant to a Terms Agreement,  the Company agrees to pay such Agent a 
commission (or grant an equivalent discount) as provided in Section 2(a) 
hereof and in accordance with the schedule set forth therein.

          Each time and date of delivery of and payment for Securities to be 
purchased by an Agent as principal, whether set forth in a Terms Agreement or 
in accordance with the Procedure, is referred to herein as a "Time of 
Delivery".

          (c)  Procedural details relating to the issue and delivery of 
Securities, the solicitation of offers to purchase Securities and the payment 
in each case therefor shall be as set forth in the Procedure. The provisions 
of the Procedure shall apply to all transactions contemplated hereunder other 
than those made pursuant to a Terms Agreement. Each Agent, XTRA and the 
Company agree to perform the respective duties and obligations specifically 
provided to be performed by each of them in the Procedure. The Company and 
XTRA will furnish to the Trustee a copy of the Procedure as from time to time 
in effect.

          3.  The documents required to be delivered pursuant to Section 6 
hereof on the Commencement Date (as defined below) shall be delivered to the 
Agents at the offices of Sullivan & Cromwell, 125 Broad Street, New York, New 
York 10004, at 2:00 p.m., New York City time, on the date of this Agreement, 
which date and time of such delivery may be postponed by agreement between 
the Agents and the Company and XTRA but in no event shall be later than the 
day prior to the date on which solicitation of offers to purchase Securities 
is commenced or on which any Terms Agreement is executed (such time and date 
being referred to herein as the "Commencement Date").

          4. The Company and XTRA covenant and agree with each Agent:

          (a)  (i) To prepare the Prospectus, as amended and supplemented, in 
a form approved by such Agent and (A) to file such Prospectus pursuant to 
Rule 424(b) under the Act not later than the Commission's close of business 
on the second business day following the acceptance of an offer to purchase a 
Security (as described in the Procedure pursuant to Section 2(c) of this 
Agreement) or (B) to file such Prospectus pursuant to Rule 424(b) under the 
Act not later than the Commission's close of business on the second business 
day following the execution and delivery of the Terms Agreement relating to 
the Purchased Securities (as defined therein); (ii) to make no amendment or 
supplement to the Registration Statement or the Prospectus (A) 

                                    -9-

<PAGE>

prior to the Commencement Date which shall be disapproved by any Agent 
promptly after reasonable notice thereof or (B) after the date of any Terms 
Agreement or other agreement by an Agent to purchase Securities as principal 
and prior to the related Time of Delivery which shall be disapproved by any 
Agent party to such Terms Agreement or so purchasing as principal promptly 
after reasonable notice thereof, in each case such approval not to be 
unreasonably withheld or delayed; (iii) to make no such amendment or 
supplement, other than a Pricing Supplement, at any other time prior to 
having afforded each Agent a reasonable opportunity to review and comment 
thereon; (iv) to file promptly all reports and any definitive proxy or 
information statements required to be filed by XTRA or the Company with the 
Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act 
for so long as the delivery of a prospectus is required in connection with 
the offering or sale of the Securities, and during such same period to advise 
such Agent, promptly after XTRA or the Company receives notice thereof, of 
the time when any amendment to the Registration Statement has been filed or 
has become effective or any supplement to the Prospectus or any amended 
Prospectus (other than any Pricing Supplement that relates to Securities not 
purchased through or by such Agent) has been filed with the Commission, of 
the issuance by the Commission of any stop order or of any order preventing 
or suspending the use of any prospectus relating to the Securities, of the 
suspension of the qualification of the Securities for offering or sale in any 
jurisdiction, of the initiation or threatening of any proceeding for any such 
purpose, or of any request by the Commission for the amendment or supplement 
of the Registration Statement or Prospectus or for additional information; 
and (v) in the event of the issuance of any such stop order or of any such 
order preventing or suspending the use of any such prospectus or suspending 
any such qualification, to use promptly its best efforts to obtain its 
withdrawal;

          (b)  Promptly from time to time to take such action as such Agent 
may reasonably request to qualify the Securities for offering and sale under 
the securities laws of such jurisdictions as such Agent may request and to 
comply with such laws so as to permit the continuance of sales and dealings 
therein for as long as may be necessary to complete the distribution or sale 
of the Securities; provided, however, that in connection therewith neither 
the Company nor XTRA shall be required to qualify as a foreign corporation or 
to file a general consent to service of process in any jurisdiction;

          (c)  To furnish each Agent with copies of the Registration 
Statement and each amendment thereto, and with copies of the Prospectus as 
each time amended or supplemented, other than any Pricing Supplement (except 
as provided in the Procedure), in the form in which it is filed with the 
Commission pursuant to Rule 424 under the Act, both in such quantities as 
such Agent may reasonably request from time to time; and, if the delivery of 
a prospectus is required at any time in connection with the offering or sale 
of the Securities (including Securities purchased from the Company and XTRA 
by such Agent as principal) and if at such time any event shall have occurred 
as a result of which the Prospectus as then amended or supplemented would 
include an untrue statement of a material fact or omit to state any material 
fact necessary in order to make the statements therein, in the light of the 
circumstances under which they were made when such Prospectus is delivered, 
not misleading, or, if for any other reason it shall be necessary during such 
same period to amend or supplement the Prospectus or to file under the 
Exchange Act any document incorporated by reference in the Prospectus in 
order to comply with the Act, the Exchange Act or the Trust 

                                    -10-

Indenture Act, to notify such Agent and request such Agent, in its capacity 
as agent of the Company and XTRA, to suspend solicitation of offers to 
purchase Securities from the Company and XTRA and, if so notified, such Agent 
shall cease such solicitations as soon as practicable, but in any event not 
later than one business day later; and if the Company or XTRA shall decide to 
amend or supplement the Registration Statement or the Prospectus as then 
amended or supplemented, to so advise such Agent promptly by telephone (with 
confirmation in writing) and to prepare and cause to be filed promptly with 
the Commission an amendment or supplement to the Registration Statement or 
the Prospectus as then amended or supplemented that will correct such 
statement or omission or effect such compliance; provided, however, that if 
during such same period such Agent continues to own Securities purchased from 
the Company and XTRA by such Agent as principal, the Company and XTRA shall 
promptly prepare and file with the Commission such an amendment or supplement;

          (d)  To make generally available to its securityholders as soon as 
practicable, but in any event not later than eighteen months after the 
effective date of the Registration Statement (as defined in Rule 158(c) under 
the Act), an earnings statement of XTRA and its subsidiaries, including the 
Company (which need not be audited), complying with Section 11(a) of the Act 
and the rules and regulations of the Commission thereunder (including, at the 
option of the Company, Rule 158);

          (e)  So long as any Securities are outstanding, to furnish to such 
Agent copies of all reports or other communications (financial or other) 
furnished to stockholders, and deliver to such Agent (i) as soon as they are 
available, copies of any reports and financial statements furnished to or 
filed with the Commission or any national securities exchange on which any 
class of securities of XTRA or the Company is listed; and (ii) such 
additional information concerning the business and financial condition of  
XTRA and the Company as such Agent may from time to time reasonably request 
(such financial statements to be on a consolidated basis to the extent the 
accounts of XTRA and its subsidiaries, including the Company, are 
consolidated in reports furnished to their stockholders generally or to the 
Commission but including such detail concerning the business and financial 
condition of the Company and its subsidiaries as the Agents may reasonably 
request);

          (f)  That, from the date of any Terms Agreement and continuing to 
and including the earlier of (i) the termination of the trading restrictions 
for the Securities purchased thereunder, as notified to the Company or XTRA 
by the Agents and (ii) the related Time of Delivery, neither the Company nor 
XTRA will, without the prior written consent of such Agent, offer, sell, 
contract to sell or otherwise dispose of any debt securities of the Company 
or XTRA which mature more than nine months after such Time of Delivery and 
which are substantially similar to the Securities;

          (g)  That each acceptance by the Company and XTRA of an offer to 
purchase Securities hereunder, and each execution and delivery by the Company 
and XTRA of a Terms Agreement with such Agent, shall be deemed to be an 
affirmation to such Agent that the representations and warranties of the 
Company and XTRA contained in or made pursuant to this Agreement are true and 
correct as of the date of such acceptance or of such Terms

                                    -11-

<PAGE>

Agreement, as the case may be, as though made at and as of such date, and an 
undertaking that such representations and warranties will be true and correct 
as of the settlement date for the Securities relating to such acceptance or 
as of the Time of Delivery relating to such sale, as the case may be, as 
though made at and as of such date (except that such representations and 
warranties shall be deemed to relate to the Registration Statement and the 
Prospectus as amended and supplemented relating to such Securities);

          (h)  That reasonably in advance of each time the Registration 
Statement or the Prospectus shall be amended or supplemented (other than by a 
Pricing Supplement) and each time a document filed under the Act or the 
Exchange Act is incorporated by reference into the Prospectus, and each time 
the Company and XTRA sell Securities to such Agent as principal pursuant to a 
Terms Agreement and such Terms Agreement specifies the delivery of an opinion 
or opinions by Sullivan & Cromwell, counsel to the Agents, as a condition to 
the purchase of Securities pursuant to such Terms Agreement, the Company and 
XTRA shall furnish to such counsel such papers and information as they may 
reasonably request to enable them to furnish to such Agent the opinion or 
opinions referred to in Section 6(b) hereof;

          (i)  That each time the Registration Statement or the Prospectus 
shall be amended or supplemented (other than by a Pricing Supplement), each 
time a document filed under the Act or the Exchange Act is incorporated by 
reference into the Prospectus, and each time the Company and XTRA sell 
Securities to such Agent as principal pursuant to a Terms Agreement and such 
Terms Agreement specifies the delivery of an opinion under this Section 4(i) 
as a condition to the purchase of Securities pursuant to such Terms 
Agreement, the Company and XTRA shall furnish or cause to be furnished 
forthwith to such Agent a written opinion of Ropes & Gray, counsel for the 
Company and XTRA, or other counsel for the Company and XTRA satisfactory to 
such Agent, and of James R. Lajoie, general counsel for the Company and XTRA, 
respectively, dated the date of such amendment, supplement, incorporation or 
Time of Delivery relating to such sale, as the case may be, in form 
satisfactory to such Agent, in each case to the effect that such Agent may 
rely on the opinion of such counsel referred to in Section 6(c) and Section 
6(d), respectively, hereof which was last furnished to the Agents to the same 
extent as though it were dated the date of such letter authorizing reliance 
(except that the statements in such last opinion shall be deemed to relate to 
the Registration Statement and the Prospectus as amended and supplemented to 
such date) or, in lieu of such opinion, an opinion of the same tenor as the 
opinion referred to in Section 6(c) and Section 6(d), respectively, hereof 
but modified to relate to the Registration Statement and the Prospectus as 
amended and supplemented to such date; 

          (j)  That each time the Registration Statement or the Prospectus 
shall be amended or supplemented and each time that a document filed under 
the Act or the Exchange Act is incorporated by reference into the Prospectus, 
in either case to set forth financial information included in or derived from 
XTRA's consolidated financial statements or one of XTRA's or the Company's 
accounting records, and each time the Company and XTRA sell Securities to an 
Agent as principal pursuant to a Terms Agreement and such Terms Agreement 
specifies the delivery of a letter under this Section 4(j) as a condition to 
the purchase of Securities pursuant to such Terms Agreement, the Company and 
XTRA shall cause the independent certified public accountants who have 
certified the financial statements of XTRA and its direct and indirect

subsidiaries, including the Company, included or incorporated by reference in 
the Registration Statement forthwith to furnish such Agent a letter, dated 
the date of such amendment, supplement, incorporation or Time of Delivery 
relating to such sale, as the case may be, in form satisfactory to such 
Agent, of the same tenor as the letter referred to in Section 6(e)(i) hereof 
but modified to relate to the Registration Statement and the Prospectus as 
amended or supplemented to the date of such letter, with such changes as may 
be necessary to reflect changes in the financial statements and other 
information derived from the accounting records of XTRA and the Company, to 
the extent such financial statements and other information are available as 
of a date not more than five business days prior to the date of such letter; 
provided, however, that, with respect to any financial information or other 
matter, such letter may reconfirm as true and correct at such date as though 
made at and as of such date, rather than repeat, statements with respect to 
such financial information or other matter made in the letter referred to in 
Section 6(e)(i) hereof which was last furnished to such Agent;

          (k)  That each time the Registration Statement or the Prospectus 
shall be amended or supplemented (other than by a Pricing Supplement), each

reference into the Prospectus and each time the Company and XTRA sell 
Securities to such Agent as principal pursuant to a Terms Agreement and such 
Terms Agreement specifies the delivery of a certificate under this Section 
4(k) as a condition to the purchase of Securities pursuant to such Terms 
Agreement, the Company and XTRA shall furnish or cause to be furnished 
forthwith to such Agent a certificate or certificates, dated the date of such 
supplement, amendment, incorporation or Time of Delivery relating to such 
sale, as the case may be, in such form and executed by such officers of the 
Company and XTRA as shall be satisfactory to such Agent, to the effect that 
the statements contained in the certificate or certificates referred to in 
Section 6(h) hereof which was last furnished to such Agent are true and 
correct at such date as though made at and as of such date (except that such 
statements shall be deemed to relate to the Registration Statement and the 
Prospectus as amended and supplemented to such date) or, in lieu of such 
certificate, certificates of the same tenor as the certificates referred to 
in said Section 6(h) but modified to relate to the Registration Statement and 
the Prospectus as amended and supplemented to such date; and

          (l)  To offer to any person who has agreed to purchase Securities 
as the result of an offer to purchase solicited by the Agents the right to 
refuse to purchase and pay for such Securities if, on the related settlement 
date fixed pursuant to the Procedure, any condition set forth in any of 
Section 6(a)(i), 6(f)(x) and (z) or 6(g) hereof shall not have been satisfied 
(it being understood that the judgment of such person with respect to the 
impracticability or inadvisability of such purchase of Securities shall be 
substituted, for purposes of this Section 4(l), for the respective judgments 
referred to therein of such Agent with respect to certain matters referred to 
in such Sections 6(a)(i), 6(f)(x) and (z) and 6(g), and that such Agent shall 
have no duty or obligation whatsoever to exercise the judgment permitted 
under such Sections 6(a)(i), 6(f)(x) and (z) and 6(g) on behalf of any such 
person).

Agents in connection with the establishment of the program contemplated 
hereby and the transactions contemplated hereunder; (iii) the out-of- pocket

XTRA's obligations hereunder which are not otherwise specifically provided 
for in this Section. It is understood, however, that except as provided in 
this Section and Sections 7 and 8 hereof, each Agent will pay all other costs 
and expenses it incurs.

          6.  The obligation of any Agent, as agent of the Company and XTRA, 
at any time ("Solicitation Time") to solicit offers to purchase the 
Securities and the obligation of such Agent to purchase Securities as 
principal pursuant to any Terms Agreement shall in each case be subject, in 
such Agent's discretion, (i) to the condition that all representations and 
warranties and other statements of the Company and XTRA herein (and, in the 
case of an obligation of an Agent under a Terms Agreement, in or incorporated 
by reference in such Terms Agreement) are true and correct (a) at and as of 
the Commencement Date and (b) any applicable date referred to in Section 4(k) 
hereof that is after such Commencement Date and prior to such Solicitation 
Time or Time of Delivery, as the case may be, and (c) at and as of such 
Solicitation Time or Time of Delivery, as the case may be, and (ii) the

obligations hereunder theretofore to be performed and the following 
additional conditions:

as amended or supplemented and other related matters as such Agent may 
reasonably request, and (ii) if and to the extent requested by such Agent, 
with respect to each applicable date referred to in Section 4(h) hereof that 
is on or prior to such Solicitation Time or Time of Delivery, as the case may 
be, an opinion or opinions, dated such applicable date, to the effect that 
such Agent may rely on the opinion or opinions which were last furnished to

statements in such last opinion or opinions shall be deemed to relate to the 
Registration Statement and the Prospectus as amended and supplemented to such 
date) or, in any case, in lieu of such an opinion or opinions, an opinion or 
opinions of the same tenor as the opinion or opinions referred to in clause

     corporation in good standing under the laws of the State of Maine, in 
     each case, with corporate power to own its properties and conduct its 
     business as described in the Prospectus (such counsel being entitled to 
     rely upon an opinion of Pierce Atwood or other counsel satisfactory to 
     the Agents in respect of matters of Maine law, provided such counsel 
     shall state that he believes both the Agents and such counsel are

          (vi)  Each Guarantee, when executed and delivered pursuant to the

     legally binding instrument of the Guarantor, enforceable in

     applicability relating to or affecting creditors' rights and

          (ix)  No consent, approval, authorization, order, registration or
     qualification of or with any court or governmental agency or

     contemplated hereby (it being understood that
     counsel's opinion need only cover federal, Massachusetts and
     the Delaware business corporation law);

          (x)  The Registration Statement and the Prospectus and any amendments
     and supplements thereto made by XTRA or the Company prior to the
     date of such opinion (other than the financial statements
     including the notes and schedules thereto, any financial
     data set forth or referred to in the Registration Statement
     or the Prospectus or any statements or omissions made by
     XTRA and the Company in reliance upon information furnished
     in writing to XTRA and the Company by the Agents in
     connection with the Registration Statement or Prospectus, as
     to which such counsel need express no opinion) comply as to
     form in all material respects with the requirements of the
     Act and the Trust Indenture Act and the rules and
     regulations thereunder; such counsel do not know of any
     legal or governmental proceedings to which XTRA or any of
     its subsidiaries, including the Company, is a party or of
     which any of their property is the subject required to be
     described in the Prospectus which are not described as
     required therein; such counsel have no reason to believe
     that, as of the effective date of the Registration
     Statement, either the Registration Statement or the
     Prospectus (or, as of its date, any amendment or supplement
     thereto made by XTRA or the Company prior to the date of
     such opinion) (other than the financial statements including
     the notes and schedules thereto, any financial data set
     forth or referred to in the Registration Statement or the
     Prospectus or any statements or omissions made by XTRA and
     the Company in reliance upon information furnished in
     writing to XTRA and the Company by the Agents in connection
     with the Registration Statement or Prospectus, as to which
     such counsel need express no opinion) contained an untrue
     statement of a material fact or omitted to state a material
     fact required to be stated therein or necessary to make the
     statements therein not misleading or that, as of the date of
     such opinion, either the Registration Statement or the
     Prospectus (or any such amendment or supplement thereto)
     contained as of its date or contains an untrue statement of
     a material fact or omits to state a material fact required
     to be stated therein or necessary to make the statements
     therein not misleading (in the case of any such opinion as
     of such date, in light of the circumstances under which they
     were made, and in each case excluding any statement in any
     such document which does not constitute part of the
     Registration Statement or the Prospectus pursuant to Rule
     412 of Regulation C under the Act), or that as of the date
     of such opinion it is necessary to amend or supplement the
     Registration Statement or Prospectus, except to file Pricing
     Supplements pursuant to Rule 424(b) under the Act; and they
     do not know of any contracts or other documents of a
     character required to be filed as an exhibit to the
     Registration Statement or required to be incorporated by
     reference into the Prospectus as amended or supplemented or
     required to be described in the Registration Statement or
     the Prospectus as amended or supplemented which are not
     filed or incorporated by reference or described as required;

          (d)  James R. Lajoie, general counsel for XTRA and the Company, 
shall have furnished to the Agents his written opinions, dated the 
Commencement Date and each applicable date referred to in Section 4(i) that 
is on or prior to such Solicitation Time or Time of Delivery, as the case may 
be, in form and substance satisfactory to the Agents, to the effect set forth 
in subsection (x) of Section 6(c) above and, additionally, as follows:

                                     -17-

<PAGE>

          (i)  Neither XTRA nor the Company is required to be qualified as a
     foreign corporation under the laws of any jurisdictions in which the
     consequences of a failure to so qualify, individually or in
     the aggregate, would have a material adverse effect on the
     business of XTRA or the Company and their respective
     subsidiaries (in each case taken as a whole);

          (ii)  Each of X-L-Co., Inc., Distribution International Corporation,
     Strick Canada Limited, XTRA Intermodal, Inc., XTRA
     International Ltd., XLI, Inc. and XTRA Lease, Inc. has been
     duly incorporated and is validly existing as a corporation
     in good standing under the laws of its jurisdiction of
     incorporation and has been duly qualified as a foreign
     corporation for the transaction of business and is in good
     standing under the laws of each other jurisdiction in which
     it owns or leases properties, or conducts any business, so
     as to require such qualification and in which the
     consequences of a failure to so qualify would have a
     material adverse effect on the business of XTRA or the
     Company and their respective subsidiaries (in each case
     taken as a whole); and all of the issued shares of capital
     stock of the Company and of each of its subsidiaries have
     been duly and validly authorized and issued, are fully paid
     and non-assessable, and (except for directors' qualifying
     shares and except as otherwise set forth in the Prospectus)
     are owned directly by XTRA (in the case of the Company) or
     the Company or indirectly through one or more subsidiaries,
     free and clear, to the best of such counsel's knowledge, of
     all liens, encumbrances, equities or claims (such counsel
     being entitled to rely in respect of the opinion in this
     clause upon opinions of local counsel and in respect of
     matters of fact upon certificates of officers of XTRA or its
     direct or indirect subsidiaries, including the Company,
     provided that such counsel shall state that he believes that
     both you and he are justified in relying upon such opinions
     and certificates);

          (iii)  To the best of such counsel's knowledge there are no legal or
     governmental proceedings pending to which XTRA or any of its
     subsidiaries, including the Company, is a party or of which
     any property of XTRA or any of its subsidiaries, including
     the Company, is the subject, other than as set forth in the
     Prospectus and other than litigation incident to the kind of
     business conducted by XTRA and its subsidiaries, including
     the Company, which individually and in the aggregate is not
     material to XTRA and its subsidiaries, including the
     Company; and to the best of such counsel's knowledge no such
     proceedings are threatened by governmental authorities or
     others;

          (iv)  The issue and sale of the Securities, the compliance by XTRA 
     and the Company with, as applicable, all of the provisions of the
     Securities, the Indenture, the Guarantee, this Agreement and
     any applicable Terms Agreement, and consummation of the
     transactions herein and therein contemplated will not result
     in (x) a breach or violation of any of the terms or
     provisions of any statute, XTRA's Certificate of
     Incorporation, the Company's Articles of Incorporation, the
     Company's or XTRA's By-laws, or any order, rule or
     regulation known to such counsel of any court or
     governmental agency or body having jurisdiction over XTRA or
     the Company or any of their respective subsidiaries or any
     of their properties or (y) a breach or violation of any of
     the terms or provisions of, or constitute a default under,
     any indenture, mortgage, deed of trust, loan agreement or
     other agreement or instrument known to such counsel to which
     XTRA or any of its 

                                     -18-

<PAGE>

     subsidiaries, including the Company, is a
     party or by which XTRA or any of its subsidiaries, including
     the Company, is bound, in each case in this provision (y)
     the consequences of which would in any way affect the
     issuance and sale of the Securities (including the
     Guarantee), the performance of this Agreement or the
     transactions contemplated hereby or the Guarantee, or
     otherwise, individually or in the aggregate, have a material
     adverse effect on the business of XTRA or the Company and
     their respective subsidiaries (in each case taken as a
     whole);

          (v)  No consent, approval, authorization, order, registration or
     qualification of or with any court or governmental agency or
     body is required for the solicitation of offers to purchase
     Securities, the issue and sale of the Securities, the
     compliance by XTRA or the Company with all the provisions of
     the Securities, the consummation by XTRA or the Company of
     the transactions contemplated by this Agreement, any
     applicable Terms Agreement or the Indenture or the
     Guarantee, except such as have been obtained under the Act
     and such as may be required under state securities or Blue
     Sky laws in connection with the solicitation by the Agents
     of offers to purchase securities from the Company and with
     purchases of Securities by the Agents as principal, as the
     case may be, in each case in the manner contemplated hereby; 

          (vi)  The documents incorporated by reference in the Prospectus 
     (other than the financial statements, including the notes and schedules
     thereto, or any financial data set forth or referred to
     therein, as to which such counsel need express no opinion),
     when they became effective or were filed with the
     Commission, as the case may be, complied as to form in all
     material respects with the requirements of the Act or
     Exchange Act, as applicable, and the published rules and
     regulations of the Commission thereunder; and such counsel
     has no reason to believe that any of such documents (other
     than the financial statements, including the notes thereto
     or any financial data set forth or referred to therein, as
     to which such counsel need express no opinion), when they
     became effective or were so filed, contained an untrue
     statement of a material fact or omitted to state a material
     fact required to be stated therein or necessary in order to
     make the statements therein, in the light of the
     circumstances under which they were made when such documents
     were so filed, not misleading;

          (e)  Not later than 10:00 a.m., New York City time, on the 
Commencement Date and on each applicable date referred to in Section 4(j) 
hereof that is on or prior to such Solicitation Time or Time of Delivery, as 
the case may be, the independent certified public accountants who have 
certified the financial statements of XTRA and its direct and indirect 
subsidiaries, including the Company, included or incorporated by reference in 
the Registration Statement shall have furnished to such Agent a letter, dated 
the Commencement Date or such applicable date, as the case may be, in form 
and substance satisfactory to such Agent, to the effect set forth in Annex 
III hereto;

          (f)  (i) Neither XTRA nor any of its subsidiaries, including the 
Company, shall have sustained since the date of the latest audited financial 
statements included or incorporated by reference in the Prospectus as amended 
or supplemented any loss or interference with its business from fire, 
explosion, flood or other calamity, whether or not covered by insurance, 

                                     -19

<PAGE>

or from any labor dispute or court or governmental action, order or decree, 
otherwise than as set forth or contemplated in the Prospectus as amended or 
supplemented and (ii) since the respective dates as of which such information 
is given in the Prospectus as amended or supplemented there shall not have 
been (x) any change in the capital stock (other than issuances of capital 
stock pursuant to the provisions of employee or director benefit or stock 
option plans or agreements of XTRA) or (y) any increase in excess of $50 
million in the long-term debt of XTRA or any of its subsidiaries, including 
the Company, or (z) any change, or any development involving a prospective 
change, in or affecting the general affairs, management, financial position, 
stockholders' equity or results of operations of XTRA and its subsidiaries, 
including the Company, otherwise than as set forth or contemplated in the 
Prospectus as amended or supplemented the effect of which, in any such case 
described in clause (i) or (ii), is in the judgment of the Agents so material 
and adverse as to make it impracticable or inadvisable to proceed with the 
solicitation by the Agents of offers to purchase Securities from XTRA and the 
Company or the purchase by the Agents of Securities from XTRA and the Company 
as principal, as the case may be;

          (g)  There shall not have occurred any of the following:  (i) a 
suspension or material limitation in trading in securities generally on the 
New York Stock Exchange; (ii) a general moratorium on commercial banking 
activities in New York declared by either federal or New York State 
authorities; (iii) the outbreak or escalation of hostilities involving the 
United States or the declaration by the United States of a national emergency 
or war if the effect of any such event specified in this clause (iii) in the 
judgment of the Agents makes it impracticable or inadvisable to proceed with 
the solicitation of offers to purchase Securities or the purchase of 
Securities from XTRA and the Company as principal pursuant to the applicable 
Terms Agreement, as the case may be; or (iv) any downgrading in the rating 
accorded the Company's debt securities by any "nationally recognized 
statistical rating organization", as that term is defined by the Commission 
for purposes of Rule 436(g)(2) under the Act; or (v) any such "nationally 
recognized statistical rating organization" shall have publicly announced 
that it has under surveillance or review, with possible negative 
implications, its rating of any of the Company's debt securities; and

          (h)  XTRA and the Company shall have furnished or caused to be 
furnished to such Agent certificates of officers of XTRA and the Company 
dated the Commencement Date and each applicable date referred to in Section 
4(k) that is on or prior to such Solicitation Time or Time of Delivery, as 
the case may be, in such form and executed by such officers of XTRA and the 
Company as shall be satisfactory to such Agent, as to the accuracy of the 
representations and warranties of XTRA and the Company herein at and as of 
the Commencement Date or such applicable date, as the case may be, as to the 
performance by XTRA and the Company of all of its obligations hereunder to be 
performed at or prior to the Commencement Date or such applicable date, as 
the case may be, as to the matters set forth in subsections (a) and (f) of 
this Section 6, and as to such other matters as such Agent may reasonably 
request.

          7.  (a)  XTRA and the Company will, jointly and severally, 
indemnify and hold harmless each Agent against any losses, claims, damages or 
liabilities, joint or several, to which such Agent may become subject, under 
the Act or otherwise, insofar as such losses, 

                                    -20-

<PAGE>

claims, damages or liabilities (or actions in respect thereof) arise out of 
or are based upon an untrue statement or alleged untrue statement of a 
material fact contained in any Preliminary Prospectus, the Registration 
Statement, the Prospectus, the Prospectus as amended or supplemented or any 
other prospectus relating to the Securities, or any amendment or supplement 
thereto, or arise out of or are based upon the omission or alleged omission 
to state therein a material fact required to be stated therein or necessary 
to make the statements therein not misleading, and will reimburse such Agent 
for any legal or other expenses reasonably incurred by it in connection with 
investigating or defending any such action or claim as such expenses are 
incurred; provided, however, that XTRA and Company shall not be liable in any 
such case to the extent that any such loss, claim, damage or liability arises 
out of or is based upon an untrue statement or alleged untrue statement or 
omission or alleged omission made in any Preliminary Prospectus, the 
Registration Statement, the Prospectus, the Prospectus as amended or 
supplemented or any other prospectus relating to the Securities, or any such 
amendment or supplement, in reliance upon and in conformity with written 
information furnished to XTRA and Company by any such Agent expressly for use 
in the Prospectus as amended or supplemented.

          (b)  Each Agent will indemnify and hold harmless XTRA and the 
Company against any losses, claims, damages or liabilities to which XTRA and 
the Company may become subject, under the Act or otherwise, insofar as such 
losses, claims, damages or liabilities (or actions in respect thereof) arise 
out of or are based upon an untrue statement or alleged untrue statement of a 
material fact contained in any Preliminary Prospectus, the Registration 
Statement, the Prospectus, the Prospectus as amended or supplemented or any 
other prospectus relating to the Securities, or any amendment or supplement 
thereto, or arise out of or are based upon the omission or alleged omission 
to state therein a material fact required to be stated therein or necessary 
to make the statements therein not misleading, in each case to the extent, 
but only to the extent, that such untrue statement or alleged untrue 
statement or omission or alleged omission was made in any Preliminary 
Prospectus, the Registration Statement, the Prospectus, the Prospectus as 
amended or supplemented or any other prospectus relating to the Securities, 
or any such amendment or supplement, in reliance upon and in conformity with 
written information furnished to XTRA and the Company by such Agent expressly 
for use therein; and will reimburse XTRA and the Company for any legal or 
other expenses reasonably incurred by XTRA and the Company in connection with 
investigating or defending any such action or claim as such expenses are 
incurred.

          (c)  Promptly after receipt by an indemnified party under 
subsection (a) or (b) above of notice of the commencement of any action, such 
indemnified party shall, if a claim in respect thereof is to be made against 
the indemnifying party under such subsection, notify the indemnifying party 
in writing of the commencement thereof; but the omission so to notify the 
indemnifying party shall not relieve it from any liability which it may have 
to any indemnified party otherwise than under such subsection. In case any 
such action shall be brought against any indemnified party and it shall 
notify the indemnifying party of the commencement thereof, the indemnifying 
party shall be entitled to participate therein and, to the extent that it 
shall wish, jointly with any other indemnifying party similarly notified, to 
assume the defense thereof, with counsel satisfactory to such indemnified 
party (who shall not, except with the consent of the indemnified party, be 
counsel to the indemnifying party), and, after notice from 

                                    -21-

<PAGE>

the indemnifying party to such indemnified party of its election so to assume 
the defense thereof, the indemnifying party shall not be liable to such 
indemnified party under such subsection for any legal expenses of other 
counsel or any other expenses, in each case subsequently incurred by such 
indemnified party, in connection with the defense thereof other than 
reasonable costs of investigation.

          (d)  If the indemnification provided for in this Section 7 is 
unavailable to or insufficient to hold harmless an indemnified party under 
subsection (a) or (b) above in respect of any losses, claims, damages or 
liabilities (or actions in respect thereof) referred to therein, then each 
indemnifying party shall contribute to the amount paid or payable by such 
indemnified party as a result of such losses, claims, damages or liabilities 
(or actions in respect thereof) in such proportion as is appropriate to 
reflect the relative benefits received by XTRA and the Company on the one 
hand and each Agent on the other from the offering of the Securities to which 
such loss, claim, damage or liability (or action in respect thereof) relates. 
If, however, the allocation provided by the immediately preceding sentence is 
not permitted by applicable law or if the indemnified party failed to give 
the notice required under subsection (c) above, then each indemnifying party 
shall contribute to such amount paid or payable by such indemnified party in 
such proportion as is appropriate to reflect not only such relative benefits 
but also the relative fault of XTRA and the Company on the one hand and each 
Agent on the other in connection with the statements or omissions which 
resulted in such losses, claims, damages or liabilities (or actions in 
respect thereof), as well as any other relevant equitable considerations. The 
relative benefits received by XTRA and the Company on the one hand and each 
Agent on the other shall be deemed to be in the same proportion as the total 
net proceeds from the sale of Securities (before deducting expenses) received 
by the Company bear to the total commissions or discounts received by such 
Agent in respect thereof. The relative fault shall be determined by reference 
to, among other things, whether the untrue or alleged untrue statement of a 
material fact or the omission or alleged omission to state a material fact 
required to be stated therein or necessary in order to make the statements 
therein not misleading relates to information supplied by XTRA or the Company 
on the one hand or by any Agent on the other and the parties' relative 
intent, knowledge, access to information and opportunity to correct or 
prevent such statement or omission. XTRA and the Company and each Agent 
agrees that it would not be just and equitable if contribution pursuant to 
this subsection (d) were determined by per capita allocation (even if the 
Agents were treated as one entity for such purpose) or by any other method of 
allocation which does not take account of the equitable considerations 
referred to above in this subsection (d). The amount paid or payable by an 
indemnified party as a result of the losses, claims, damages or liabilities 
(or actions in respect thereof) referred to above in this subsection (d) 
shall be deemed to include any legal or other expenses reasonably incurred by 
such indemnified party in connection with investigating or defending any such 
action or claim. Notwithstanding the provisions of this subsection (d), an 
Agent shall not be required to contribute any amount in excess of the amount 
by which the total public offering price of the Securities purchased by or 
through it exceeds the amount of any damages which such Agent has otherwise 
been required to pay by reason of such untrue or alleged untrue statement or 
omission or alleged omission. No person guilty of fraudulent 
misrepresentation (within the meaning of Section 11(f) of the Act) shall be 
entitled to contribution from any person who was not guilty of such 
fraudulent misrepresentation. The obligations of each of the Agents under 
this subsection (d) to

                                    -22-

<PAGE>

contribute are several in proportion to the respective purchases made by or 
through it to which such loss, claim, damage or liability (or action in 
respect thereof) relates and are not joint.

          (e)  The obligations of XTRA and the Company under this Section 7 
shall be in addition to any liability which XTRA and the Company may 
otherwise have and shall extend, upon the same terms and conditions, to each 
person, if any, who controls any Agent within the meaning of the Act; and the 
obligations of each Agent under this Section 7 shall be in addition to any 
liability which such Agent may otherwise have and shall extend, upon the same 
terms and conditions, to each officer and director of XTRA and the Company 
and to each person, if any, who controls XTRA or the Company within the 
meaning of the Act.

          8.  Each Agent, in soliciting offers to purchase Securities from 
the Company and XTRA and in performing the other obligations of such Agent 
hereunder (other than in respect of any Terms Agreement), is acting solely as 
agent for the Company and XTRA and not as principal. Each Agent will make 
reasonable efforts to assist the Company and XTRA in obtaining performance by 
each purchaser whose offer to purchase Securities from the Company and XTRA 
was solicited by such Agent and has been accepted by the Company and XTRA, 
but such Agent shall not have any liability to the Company and XTRA in the 
event such purchase is not consummated for any reason. If the Company or XTRA 
shall default on its obligation to deliver Securities to a purchaser whose 
offer it has accepted, the Company and XTRA shall (i) hold each Agent 
harmless against any loss, claim or damage arising from or as a result of 
such default by the Company and XTRA and (ii) notwithstanding such default, 
pay to the Agent that solicited such offer any commission to which it would 
be entitled in connection with such sale.  The Company and XTRA shall not be 
required to pay any Agent a commission in connection with any purchase of a 
Security which is not consummated other than as a result of a default by the 
Company or XTRA of its obligations hereunder, including their obligation to 
deliver Securities to a purchaser whose offer has been accepted.

          9.  The respective indemnities, agreements, representations, 
warranties and other statements by any Agent and XTRA and the Company set 
forth in or made pursuant to this Agreement shall remain in full force and 
effect regardless of any investigation (or any statement as to the results 
thereof) made by or on behalf of any Agent or any controlling person of any 
Agent or either of XTRA or the Company, or any officer or director or any 
controlling person of either of XTRA or the Company, and shall survive each 
delivery of and payment for any of the Securities.

          10.  The provisions of this Agreement relating to the solicitation 
of offers to purchase Securities from the Company and XTRA may be suspended 
or terminated at any time by the Company and XTRA as to any Agent or by any 
Agent as to such Agent upon the giving of written notice of such suspension 
or termination to such Agent or the Company or XTRA, as the case may be. In 
the event of such suspension or termination with respect to any Agent, (x) 
this Agreement shall remain in full force and effect with respect to any 
Agent as to which such suspension or termination has not occurred, (y) this 
Agreement shall remain in full force and effect with respect to the rights 
and obligations of any party which have previously accrued or which relate to 
Securities which are already issued, agreed to be issued or the subject of a 
pending offer at the time of such suspension or termination and (z) in any 
event, 

                                     -23-

<PAGE>

this Agreement shall remain in full force and effect insofar as the third 
paragraph of Section 2(a) (with respect to solicitations made prior to such 
suspension or termination), Section 4(d), Section 4(e), Section 5 (with 
respect to solicitations made prior to such suspension or termination), 
Section 7, Section 8 and Section 9 are concerned.

          11.  Except as otherwise specifically provided herein or in the

                     selected by the purchaser and
                     agreed to by the Company, which
                     will be at least nine months but
                     not more than thirty years from the

                     thereof. Global Securities (as defined

                     an aggregate principal amount in excess
                     of $200,000,000 would, but for the
                     preceding sentence, be represented by a
                     single Global Security, then one Global
                     Security will be authenticated and
                     issued to represent each $200,000,000
                     principal amount of such Book-Entry Note
                     or Notes and an additional Global

                     issued to represent any remaining
                     principal amount of such Book-Entry Note
                     or Notes. In such a case, each of the
                     Global Securities representing such
                     Book-Entry Note or Notes shall be
                     assigned the same CUSIP number.

Registration:     Each Security will be issued only in
                     fully registered form and will be
                     represented by either a global
                     security (a "Global Security")

                     forth in the applicable Pricing
                     Supplement. An owner of a
                     Book-Entry Security will not be
                     entitled to receive a certificate
                     representing such a Security,
                     except as provided in the
                     Indenture.

                     be recorded through the records of such
                     Participants or through the separate

                     the Agents reserve the right to withhold
                     payment for which they have not received
                     funds from the purchaser. The Company
                     shall not use any proceeds advanced by
                     the Agents to acquire securities. The
                     Agents will obtain a written
                     acknowledgment from the purchaser of the

                     of payment for such Security in
                     immediately available funds to the
                     Company in an amount equal to the issue
                     price of the Security less the Agents'
                     discount.

  Certificated       principal) shall fail to accept
  Securities:        delivery of and make payment for
                     any Security, the Agents will
                     forthwith notify the Company's
                     Treasurer by telephone (confirmed
                     in writing) or by facsimile
                     transmission. If the Security has
                     been delivered to the Agents on
                     behalf of the purchaser, the Agents
                     will immediately return the
                     Security to the Company or its
                     agent. If funds have been advanced
                     by the Trustee or the Agents, as
                     the case may be, for the purchase
                     of such Security, the Trustee or
                     its agent will immediately upon
                     receipt of the Security debit the
                     account of the Company in an amount
                     equal to the amount previously
                     credited thereto in respect of the
                     Security and will either credit the
                     account of or return such funds to
                     the Agents, or the Company will
                     return to the Agents directly an
                     amount equal to the amount
                     previously paid by the Agents to
                     the company in respect of such
                     Security. Such debits and credits
                     or returns will be made on the
                     Settlement Date if possible and, in
                     any event, not later than the
                     business day following the
                     Settlement Date. If such failure
                     shall have occurred for any reason
                     other than default by the Agents in
                     the performance of its obligations
                     under the Distribution Agreement,
                     the Company will reimburse the
                     Agents on an equitable basis for
                     its loss of the use of the funds
                     during the period when they were
                     credited to the account of the
                     Company.

                  Immediately upon receipt of the certificate
                     representing the Security in respect of
                     which the failure occurred, the Trustee
                     or its agent will cancel the Security,
                     make appropriate entries in its records
                     and, unless otherwise instructed by the
                     Company, destroy the certificate.

                     that is at least equal to the principal

                     such order and the Company shall

                     the price of such Book-Entry Security

                  Notwithstanding the foregoing, upon any
                     failure to settle with respect to a
                     Book-Entry Security, the Depository may

                     not all, of the Book-Entry Securities to
                     have been represented by a Global
                     Security, the Trustee will provide, in

                     will make appropriate entries in its
                     records. The Company will, from time to
                     time, furnish the Trustee with a
                     sufficient quantity of Securities.

                     Company, XTRA and the Agents will
                     discuss from time to time the rates of
                     interest per annum to be borne by and

                     sold as a result of the solicitation of
                     offers by the Agents. Once a decision
                     has been reached to set initially the
                     "posted" rates or to change already
                     "posted" rates, the Company or XTRA will

                     solicitation of offers until the initial
                     or changed "posted" rates have been
                     established. When such rates have been
                     established, the Company will then
                     promptly prepare "posted" rates stickers
                     reflecting such posted rates and
                     maturities. The Company will then
                     promptly arrange to have ten Prospectus
                     Supplements so stickered filed with the
                     Commission not later than the
                     Commissioner's close of business on the
                     second business day after such "posted"
                     rates have been established and to have
                     copies of such stickered Prospectus
                     Supplements delivered to the Agents.

                     rates and maturities are to be set forth
                     on "posted" rates stickers attached to
                     Prospectus Supplements distributed to
                     potential purchasers.

                  The Agents and the Company and XTRA shall
                     destroy outdated "posted" rates stickers
                     and the Prospectus Supplements to which
                     they are attached (other than those
                     retained for files).

                     event not later than one business
                     day after, the Agents will suspend
                     solicitation until such time as the
                     Company has advised the Agents that
                     solicitation of offers to purchase
                     Securities may be resumed. Except
                     as otherwise provided for in the
                     Distribution Agreement, the Company
                     and XTRA have discretion regarding
                     whether to amend or supplement the
                     Registration Statement or
                     Prospectus. If the Company or XTRA
                     propose so to amend or supplement,
                     they will promptly advise the
                     Agents and will furnish the Agents
                     such proposed amendment or
                     supplement and, after the Agents
                     has been afforded a reasonable
                     opportunity to review such
                     amendment or supplement, will cause
                     such amendment or supplement
                     promptly to be filed with, or
                     mailed for filing to, the
                     Commission. The Company will
                     promptly provide the Agents with
                     copies of any such amendment or
                     supplement and confirm to the
                     Agents that such amendment or
                     supplement has been filed with the
                     Commission.

                  In the event that at the time the Agents
                     suspend solicitation of offers to
                     purchase Securities there shall be any
                     orders for delayed settlement
                     out-standing, the Company and XTRA,

                     orders may be settled and whether copies
                     of the Prospectus as in effect at the
                     time of the suspension may be delivered
                     in connection with the settlement of

ANNEX III
          Pursuant to Section 4(j) and Section 6(e)(i), as the
case may be, of the Distribution Agreement, XTRA's independent
certified public accountants shall furnish letters to the effect
that:

          (i)  They are independent certified public accountants with respect to
     XTRA
     and its direct and indirect subsidiaries, including the
     Company, within the meaning of the Act and the applicable
     published rules and regulations thereunder;

          (ii)  In their opinion, the financial statements and financial
     statement
     schedules audited by them and included or incorporated by
     reference in the Registration Statement or the Prospectus
     comply as to form in all material respects with the
     applicable accounting requirements of the Act or the
     Exchange Act, as applicable, and the related published rules
     and regulations thereunder;

          (iii)  They have performed the procedures specified by the American
     Institute of Certified Public Accountants for a review of
     interim financial information as described in SAS No. 71 on
     the unaudited financial statements included in XTRA's
     Quarterly Report on Form 10-Q, incorporated by reference
     into the Prospectus, and inquired of certain officials of
     XTRA who have responsibility for financial and accounting
     matters as to whether the unaudited financial statements
     comply as to form in all material respects with the
     applicable accounting requirements of the Exchange Act as it
     applies to Form 10-Q and the related published rules and
     regulations, and based on the foregoing procedures, nothing
     came to their attention that caused them to believe that any
     material modifications should be made to the unaudited
     financial statements for them to be in conformity with
     generally accepted accounting principles, or that the
     unaudited condensed consolidated financial statements do not
     comply as to form in all material respects with the
     applicable accounting requirements of the Exchange Act and
     the related published rules and regulations;

          (iv)  On the basis of limited procedures, not constituting an audit in
     accordance with generally accepted auditing standards,
     consisting of a reading of the unaudited financial
     statements, a reading of the latest available interim
     financial statements of XTRA and its direct and indirect
     subsidiaries, including the Company, inspection of the
     minute books of XTRA and its direct and indirect
     subsidiaries, including the Company, since the date of the
     latest audited financial statements included or incorporated
     by reference in the Prospectus, inquiries of officials of
     XTRA and its direct and indirect subsidiaries, including the
     Company, responsible for financial and accounting matters,
     nothing came to their attention that caused them to believe
     that:

               (A)  as of a specified date not more than five
          days prior to the date of such letter, there has been
          any increase in the consolidated long-term debt of XTRA
          and its direct and indirect subsidiaries, including the
          Company, or any decrease in the amount of XTRA's
          retained earnings, or any decreases in common stock,
          consolidated net property and equipment or lease
          contracts receivable in each case as compared with
          amounts shown on the most recently filed Form 10-Q,
          except in each case for changes, increases or decreases
          which the Prospectus discloses have occurred or may
          occur or which are described in such letter; and


<PAGE>

               (B)  for the period from the date of the latest
          financial statements included or incorporated by
          reference in the Prospectus to the specified date
          referred to in Clause (A) there were any decreases, as
          compared with the corresponding period in the preceding
          year, in the amount of XTRA's consolidated revenues, or
          income from operations before provision for income
          taxes or any decreases in the ratio of income from
          operations before provision for income taxes to
          revenues, or any increases in the ratios of
          depreciation on rental equipment, rental equipment
          operating expense (which includes repair, and
          maintenance, tires and tubes, transportation and
          storage, facilities and other expense), selling and
          administrative expense or interest expense to revenues,
          except in each case for increases or decreases which
          the Prospectus discloses have occurred or may occur or
          which are described in such letter;

          (v)  In addition to the audit referred to in their report
     (s) included or incorporated by reference in the Prospectus and the limited
     procedures, inspection of minute books, inquiries and other
     procedures referred to in paragraphs (iii) and (iv) above,
     they have carried out certain specified procedures, not
     constituting an audit in accordance with generally accepted
     auditing standards, with respect to certain amounts,
     percentages and financial information specified by the
     Agents which are derived from the general accounting records
     of XTRA and its direct and indirect subsidiaries, including
     the Company, which appear in the Prospectus (including
     documents incorporated by reference), or in Part II of, or
     in exhibits and schedules to, the Registration Statement
     specified by the Agents or in documents incorporated by
     reference in the Prospectus specified by the Agents, and
     have compared certain of such amounts, percentages and
     financial information with the accounting records of XTRA
     and its direct and indirect subsidiaries, including the
     Company, and have found them to be in agreement;

          (vi)  They compared the amounts included in the Selected 
     Financial Data to the appropriate annual reports on Form 10-K
     and found them to be in agreement. They have also compared the 
     amounts included in the selected quarterly financial data to the
     Company's accounting records, the appropriate Quarterly
     Report on Form 10-Q or the appropriate Form 10-K, and found
     them to be in agreement. They compared the information
     included in the Selected Financial Data, the Selected
     Quarterly Financial Data and the Ratios of Earnings to Fixed
     Charges and Earnings to Combined Fixed Charges and Preferred
     Stock Dividends tables with the requirements of Items 301 or
     302 or 503, respectively, of Regulation S-K. They also
     inquired of certain officials of XTRA who have
     responsibility for financial and accounting matters whether
     this information conforms in all material respects with the
     disclosure requirements of Items 301 or 302 or 503,
     respectively, of Regulation S-K. Nothing came to their
     attention to cause them to believe that the Selected
     Financial Data, the Selected Quarterly Financial Data and
     Ratios of Earnings to Fixed Charges and Earnings to Combined
     Fixed Charges and Preferred Stock Dividends did not conform
     in all material respects to the disclosure requirements of
     Rule 301 or 302 or 503, respectively, of Regulation S-K; and

          (vii)  If pro forma financial information is required to be 
     included in or incorporated by reference into the Registration 
     Statement or the Prospectus, they have


<PAGE>

               (A)  read the unaudited pro forma balance sheet
          and the unaudited pro forma statements of income
          included in or incorporated by reference into the
          Registration Statement or Prospectus;

               (B)  inquired of certain officials of XTRA (and
          the company being acquired) who have responsibility for
          financial and accounting matters about (1) the basis
          for such officials' determination of the pro forma
          adjustments; and (2) whether the unaudited pro forma
          financial statements referred to above comply as to
          form in all material respects with the applicable
          accounting requirements of Rule 11-02 of
          Regulation S-X; and

               (C)  proved the arithmetic accuracy of the
          application of the pro forma adjustments to the
          historical amounts in the unaudited pro forma financial
          statements.

          The foregoing procedures are substantially less in
scope than an examination, the object of which is the expression
of an opinion on management's assumptions, the pro forma
adjustments and the application of those adjustments to
historical financial information. Accordingly, they make no
representation about the sufficiency of such procedures for each
Agent's purposes.

          Nothing came to their attention as a result of the
procedures specified in the above paragraphs, however, that
caused them to believe that the unaudited pro forma financial
statements referred to above included in or incorporated by
reference into the Registration Statement or the Prospectus do
not comply as to form in all material respects with the
applicable accounting requirements of Rule 11-02 of Regulation
S-X and that the pro forma adjustments have not been properly
applied to the historical amounts in the compilation of those
statements. Had they performed additional procedures or had they
made an examination of the pro forma financial statements, other
matters might have come to their attention that would have been
reported to the Agents.

          All references in this Annex III to the Prospectus
shall be deemed to refer to the Prospectus (including the
documents incorporated by reference therein) as defined in the
Distribution Agreement as of the Commencement Date referred to in
Section 6(e) thereof and to the Prospectus as amended or
supplemented (including the documents incorporated by reference
therein) as of the date of the amendment, supplement,
incorporation or the Time of Delivery relating to the Terms
Agreement requiring the delivery of such letter under
Section 4(j) thereof.

    Re:  XTRA Corporation and XTRA, Inc. - 
         $604,000,000 Aggregate Amount of Securities

Ladies and Gentlemen:

    You have asked our opinion concerning the proposed issue by XTRA

    We have acted as counsel for the Company and XTRA, Inc. in connection

(No. 33-65293) (the "Registration Statement") relating to the Securities 
filed with the Securities and Exchange Commission under the Securities Act of 
1933, as amended, has been declared effective, no further authorization, 
consent or approval by any regulatory authority will be required for the 
valid issuance and sale of the Securities (except under the so-called "Blue 
Sky" or securities laws of the several states, as to the applicability of 
which we express no opinion);

    (2)  when the Board of Directors of the Company and/or XTRA, Inc. or
committees designated thereby, have determined the price and other terms and
conditions relating to the issue and sale of the Securities, the Securities will
have been duly authorized by the Company and XTRA, Inc.;

    (3)  upon the execution and filing with the Trustees of the proper papers,
the Senior Securities and the related Guarantees and the Subordinated Securities
and the related Guarantees will be issuable under the terms of their respective
Indentures;

    (4)  upon the execution, certification and delivery of the Senior
Securities and the related Guarantees in accordance with the corporate
authorization referred to above and in accordance with the Senior Indenture, the
Senior Securities will be valid and legally binding obligations of XTRA, Inc.,
and the related Guarantees will be the valid and legally binding obligations of
the Company, and the Senior Securities and related Guarantees will be entitled
to the benefits provided by the Senior Indenture together with any other series
of Senior Securities and Guarantees thereof and which may hereafter be issued
thereunder pursuant to the terms thereof; except that enforcement of the rights
and remedies created thereby is subject to bankruptcy, reorganization,
insolvency or similar laws affecting creditors' rights generally, as may from
time to time be in effect, and by the availability of specific performance or of
injunctive relief, which is subject to the discretion of the court before which
any proceeding may be brought;

authorization referred to above and in

accordance with the Subordinated Indenture, the Subordinated Securities will 
be valid and legally binding obligations of XTRA, Inc. and the related 
Guarantees will be the valid and legally binding obligations of the Company, 
and the Subordinated Securities and related Guarantees will be entitled to

brought;

payment of the agreed consideration in accordance with the corporate 
authorization referred to above, the New Common Stock will be validly issued, 
fully paid and nonassessable; and

Company's and XTRA, Inc.'s joint Registration Statement relating to the 
Securities to be filed under the Securities Act of 1933, as amended.  We 
consent to the filing of this opinion with and as part of said Registration
