Item 5.  Other Events.
- ------                

       On June 19, 1998, XTRA Corporation (the "Company") and Wheels MergerCo
LLC ("MergerCo"), a Delaware limited liability company newly formed by (i)
Apollo Management IV, L.P., on behalf of its managed funds, ("Apollo") and (ii)
Interpool, Inc. ("Interpool") and Interpool's affiliate, Atlas Capital Partners
LLC ("Atlas") (collectively, together with Apollo, the "Investors") entered into
an Agreement and Plan of Merger and Recapitalization, dated as of June 18, 1998
(the "Merger Agreement"), pursuant to which MergerCo will, subject to the terms
and conditions of the Merger Agreement, merge with and into the Company (the
"Merger"). The Company will be the surviving corporation in the Merger. The
Merger Agreement is filed herewith as Exhibit 2.1 and is incorporated by
reference herein.

       The Merger Agreement provides that the owner of each outstanding share of
common stock, par value $.50 per share, of the Company (the "Company Common
Stock") can elect either to receive $65.00 in cash for that share or to retain
that share.  This election is subject to proration so that upon consummation of
the Merger, 500,000 shares of Company Common Stock (approximately 3.3% of the
currently outstanding shares) will be retained by existing shareholders and the
balance will be exchanged for cash.

       MergerCo has received and provided the Company with (i) an executed
commitment letter from Apollo to fund $292.5 million in equity capital (less any
monies contributed by Atlas or its affiliates), and (ii) executed commitment
letters from certain financial institutions with respect to senior secured and
subordinated debt financing. All interests in MergerCo issued and outstanding
immediately prior to the Merger shall be converted into 4,500,000 shares of
Company Common Stock. Following the Merger, the Investors expect to own
approximately 90% of the outstanding Company Common Stock.

       The Merger Agreement includes provisions prohibiting the Company from
actively soliciting another acquisition proposal, and provides for the payment
of a fee of $35 million and the reimbursement of expenses up to $5 million to
the Investors, as designated by MergerCo, in the event of termination of the
Merger Agreement under certain circumstances (generally requiring the existence
of a competing third-party offer or transaction).

       Following the Merger, the Company Common Stock will not be listed on any
national securities exchange or quoted on The NASDAQ Stock Market Inc.'s
National Market.  Pursuant to the Merger Agreement, the Company has agreed not
to declare or pay any dividends prior to the consummation of the Merger.  The
Merger Agreement has been approved by the respective boards of the Company and
MergerCo, and is subject to certain conditions, including the approval of the
Company's shareholders at a meeting to be held as soon as practicable, the
expiration of antitrust regulatory waiting periods, qualification of the
transaction as a recapitalization for financial reporting purposes, and the
completion of financing arrangements.

       Concurrently with the execution of the Merger Agreement, MergerCo and
certain individuals and entities (each a "Stockholder"), who hold in the
aggregate approximately 43.5% of the outstanding Company Common Stock, entered
into voting agreements dated as of June 18, 1998 (the "Voting Agreements").
Pursuant to the Voting Agreements, each Stockholder irrevocably agreed to vote
all the shares of Company Common Stock held by it in favor of the approval and
adoption of the Merger Agreement and the transactions contemplated thereby. The
Voting Agreements are filed herewith as Exhibits 9.1 through 9.5 and are
incorporated by reference herein.

       On June 19, 1998, the Company issued a press release (the "Press
Release") announcing the execution of the Merger Agreement. The Press Release is
attached hereto as Exhibit 99.1 and is incorporated by reference herein.

the Merger and without any action on the part of the MergerCo, the Company or
the holders of any of the following securities:

     (1) Interests in MergerCo.  All of the interests in MergerCo issued and
outstanding immediately prior to the Effective Time shall be converted into a
number of Common Shares following the Merger equal to 4,500,000 Common Shares
(or such lesser number as may be determined by MergerCo prior to the mailing of
the Proxy Statement (as hereinafter defined), with each member receiving a
number of Common Shares which equals the percentage of all such shares
corresponding to its percentage of all interests of MergerCo issued and
outstanding immediately prior to the Effective Time.

     (2) Cancellation.  Each Share held in the treasury of the Company and each
Share owned by any direct or indirect wholly owned Subsidiary of the Company
immediately prior to the Effective Time shall, by virtue of the Merger and
without any action on the part of the holder thereof, cease to be outstanding,
be canceled and retired without payment of any consideration therefor and cease
to exist.

     (3) Retention of and Payment for Common Shares.  Except as otherwise
provided herein and subject to Sections 2.2 and 2.3, each Common Share issued
and outstanding immediately prior to the Effective Time shall, by virtue of the
Merger, be treated as follows:

          (i)  for each Common Share with respect to which an election to
     retain such Common Shares has been effectively made and not revoked in
     accordance with Section 2.2 (the "Potential Election Shares") and which is
     to be retained in accordance with Section 2.3(2)(ii) or Section 2.3(3), the
     right to retain such fully paid and nonassessable Common Share (an
     "Election Share");

                                       4
<PAGE>
 
          (ii)   for each Common Share which was not a Potential Election Share,
     but which is to be retained in accordance with Section 2.3(3)(ii), the
     right to retain such fully paid and non-assessable Common Share (a "Non-
     Election Share" and, together with the Election Shares, the "Retained
     Shares"); and

         (iii)   for each Common Share (other than Dissenting Shares (as defined
     in Section 2.5(10) and Retained Shares) the right to receive in cash from
     the Company following the Merger an amount equal to $65 (the "Cash Price"
     and, with the Retained Shares, the "Merger Consideration") and each such
     Common Share shall no longer be outstanding, shall automatically be
     canceled and retired and shall cease to exist, and each holder of a
     Certificate representing any such Common Shares shall, to the extent such
     Certificate represents such Shares, cease to have any rights with respect
     thereto, except the right to receive the Cash Price applicable thereto,
     upon surrender of such Certificate in accordance with Section 2.5.

     SECTION 2.2  Common Share Elections. Each person who, on or prior to the
Election Date (as defined in Section 2.2(b) below), is a record holder of Common
Shares will be entitled to make an unconditional election on or prior to such
Election Date to express a desire to retain such shares, on the basis
hereinafter set forth and subject to Section 2.3 hereof.

     (1) Subject to any required clearance by the Securities and Exchange
Commission (the "SEC"), the Company shall prepare and mail a form of election
(the "Form of Election"), which form shall be subject to the reasonable approval
of MergerCo, with the Proxy Statement to the record holders of Common Shares as
of the record date for the Special Meeting (as hereinafter defined), which Form
of Election shall be used by each record holder of Common Shares who elects to
express a desire to retain Common Shares held by such holder.   The Company will
use its best efforts to make the Form of Elections available to all persons who
become holders of Common Shares during the period between such record date and
the Election Date, with a copy of the Proxy Statement.  Any such holder's
election shall have been properly made only if the Exchange Agent shall have
received at its designated office, by 5:00 p.m., New York City time on the
second business day prior to the date of the Special Meeting (the "Election
Date"), a Form of Election properly completed and signed and accompanied by
Certificates for the Common Shares to which such Form of Election relates, duly
endorsed in blank or otherwise in a form acceptable for transfer on the books of
the Company (or by an appropriate

                                       5
<PAGE>
 
guarantee of delivery of such certificates asset forth in such Form of Election
from a firm which is a member of a registered national securities exchange or of
the National Association of Securities Dealers, Inc. or a commercial bank or
trust company having an office or correspondent in the United States, provided
such certificates are in fact delivered to the Exchange Agent within three NYSE
trading days after the date of execution of such guarantee of delivery).

     (2) Any Form of Election may be revoked by the holder submitting it to the
Exchange Agent only by written notice received by the Exchange Agent (i) prior
to 5:00 p.m., New York City time on the Election Date or (ii) after the Election
Date, if (and to the extent that) the Exchange Agent is legally required to
permit revocations and the Effective Time shall not have occurred prior to such
date.  In addition, all Forms of Election shall automatically be revoked if the
Exchange Agent is notified in writing by MergerCo and the Company that the
Merger has been abandoned.  If a Form of Election is revoked, the Certificate or
Certificates (or guaranties of delivery, as appropriate) for the Common Shares
to which such Form of Election relates shall be promptly returned to the
stockholder submitting the same to the Exchange Agent.

     (3) The determination of the Exchange Agent shall be binding with respect
to whether or not elections have been properly made or revoked pursuant to this
Section 2.2 and when elections and revocations were received by it.  If the
Exchange Agent determines that any election to retain Common Shares was not
properly made, such shares shall be treated by the Exchange Agent as shares for
which no election was received, and such shares shall be retained or converted
in accordance with Section 2.1 and 2.3.  The Exchange Agent shall also make all
computations as to the allocation and the proration contemplated by Section 2.3,
and any such computation shall be conclusive and binding on the holders of
Common Shares.  The Exchange Agent may, with the mutual agreement of MergerCo
and the Company, make such rules as are consistent with this Section 2.2 for the
implementation of the elections provided for herein as shall be necessary or
desirable fully to effect such elections.

     SECTION 2.3  Proration.

     (1) Notwithstanding anything in this Agreement to the contrary, the
"Retained Share Number" shall equal 500,000 Common Shares (or such lesser number
as is determined by MergerCo prior to the mailing of the Proxy Statement).

                                       6
<PAGE>
 
     (2) If the number of Potential Election Shares is greater than the Retained
Share Number, then each Potential Election Share shall be retained as an
Election Share in accordance with the terms of Section 2.1(3)(i) or receive cash
in accordance with the terms of Section 2.1(3)(iii) in the following manner:

         (i)    A proration factor (the "Non-Cash Proration Factor") shall be
     determined by dividing the Retained Share Number by the total number of
     Potential Election Shares.

        (ii)    The number of Potential Election Shares covered by each
     election to be retained as Election Shares shall be determined by
     multiplying the Non-Cash Proration Factor by the total number of Potential
     Election Shares covered by such election, rounded to the nearest whole
     number.

        (iii)    All Potential Election Shares, other than those shares which
     are retained in accordance with Section 2.3(2)(ii), shall be converted into
     cash in accordance with the terms of Section 2.1(3)(iii).

     (3) If the number of Potential Election Shares is less than or equal to the
Retained Share Number, then each Potential Election Share shall be retained as
an Election Share in accordance with the terms of Section 2.1(3)(i) and each
Common Share other than a Potential Election Share or a Dissenting Share (a
"Potential Cash Share") shall be retained as a Non-Election Share in accordance
with Section 2.1(3)(ii) or converted into cash in accordance with the terms of
Section 2.1(3)(iii) in the following manner:

          (i)    A proration factor (the "Cash Proration Factor") shall be
     determined by dividing (x) the difference between the Retained Share Number
     and the number of Potential Election Shares, by (y) the number of Potential
     Cash Shares.

         (ii)    The number of Potential Cash Shares held by each stockholder to
     be retained as Non-Election Shares in accordance with Section 2.1(3)(ii)
     shall be determined by multiplying the Cash Proration Factor by the total
     number of Potential Cash Shares held by such stockholder, rounded down to
     the nearest whole number.

                                       7
<PAGE>
 
        (iii)    All Potential Cash Shares, other than those shares retained as
     Non-Election Shares, shall be converted to cash in accordance with Section
     2.1(3)(iii).

     SECTION 2.4   Options; Stock Plans. (1) Except as may be agreed to by the
Company, with the consent of MergerCo, and employees identified by MergerCo
prior to the Effective Time, options to acquire Shares ("Stock Options") which
are outstanding as of the date of this Agreement and which were granted to
employees, former employees or directors under the Company's 1987 Stock
Incentive Plan, 1997 Stock Incentive Plan, 1991 Stock Option Plan for Non-
Employee Directors and Deferred Director Fee Option Plan (which are the only
stock option plans, programs or similar arrangements of the Company or any of
its Subsidiaries) (the "Option Plans") shall be canceled by the Company and
terminated, and each holder of a Stock Option who executes an agreement
acknowledging the cancellation of such Stock Option, whether or not then
exercisable, shall be entitled to receive as soon as practicable after the
Effective Time from the Company in consideration for such cancellation an amount
in cash (less applicable withholding taxes, but without interest) equal to the
product of (i) the number of Shares previously subject to such Stock Option,
multiplied by (ii) the positive excess, if any, of the Cash Price over the
exercise price per share of the Shares previously subject to such Stock Option.
The Company agrees that prior to the Effective Time it shall take all steps
necessary or appropriate under the Option Plans to effect the foregoing as of
the Effective Time. The Company shall take all necessary actions required to
properly withhold and remit to the proper taxing authorities all income,
employment and other taxes required by applicable law to be withheld from the
payment of such cash amounts.

          (2)  The Company agrees that it will take all necessary action prior
to the Effective Time to terminate the Company's Employee Stock Purchase Plan as
of the Effective Time.

     SECTION 2.5    Payment for Common Shares.

     (1) From and after the Effective Time, such bank or trust company as shall
be mutually acceptable to MergerCo and the Company shall act as exchange agent
(the "Exchange Agent").  Following the Effective Time, MergerCo shall cause to
be made available to the Exchange Agent, as and when required, an amount (the
"Exchange Fund") equal to the aggregate Merger Consideration to which holders of
Common Shares shall be entitled at the Effective Time pursuant to Section
2.1(3).

                                       8
<PAGE>
 
     (2) Promptly after the Effective Time, MergerCo shall cause the Exchange
Agent to mail to each record holder of certificates (the "Certificates") that
immediately prior to the Effective Time represented Common Shares a form of
letter of transmittal which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon proper delivery
of the Certificates to the Exchange Agent and instructions for use in
surrendering such Certificates and receiving the Merger Consideration in respect
thereof.

     (3) In effecting the payment of the Cash Price in respect of Common Shares
represented by Certificates entitled to payment of the Cash Price pursuant to
Section 2.1(3)(iv) (the "Cashed Shares"), upon the surrender of each such
Certificate, the Exchange Agent shall pay the holder of such Certificate the
Cash Price multiplied by the number of Cashed Shares, in consideration therefor.
Upon such payment (and the exchange, if any, of Certificates formerly
representing Common Shares for certificates representing Retained Shares) such
Certificate shall forthwith be cancelled.

     (4) In effecting the exchange of Retained Shares in respect of Common
Shares represented by Certificates which, at the Effective Time, shall become
Retained Shares, upon surrender of each such Certificate, the Exchange Agent
shall deliver to the holder of such Certificate a certificate representing that
number of whole Retained Shares which such holder has the right to receive
pursuant to the provisions of Section 2.1(3), and cash in lieu of fractional
Retained Shares.  Upon such exchange (and any payment of the Cash Price for
Cashed Shares), such Certificate so surrendered shall forthwith be cancelled.

     (5) Until surrendered in accordance with paragraphs (3) or (4) above, each
such Certificate (other than Certificates representing Common shares held by
MergerCo or any of its affiliates, in the treasury of the Company or by any
wholly owned subsidiary of the Company or Dissenting Shares) shall represent
solely the right to receive the aggregate Merger Consideration relating thereto.
No interest or dividends shall be paid or accrued on the Merger Consideration.
If the Merger Consideration (or any portion thereof) is to be delivered to any
person other than the person in whose name the Certificate formerly representing
Common Shares surrendered therefor is registered, it shall be a condition to
such right to receive such Merger Consideration that the Certificate so
surrendered shall be properly endorsed or otherwise be in proper form for
transfer and that the person surrendering such Common Shares shall pay to the
Exchange Agent any transfer or other rates required by reason of the payment of
the Merger Consideration to a person other than the 

                                       9
<PAGE>
 
registered holder of the Certificate surrendered, or shall establish to the
satisfaction of the Exchange Agent that such tax has been paid or is not
applicable.

     (6) Distributions with Respect to Unexchanged Shares.  No dividends or
other distributions with respect to Common Shares with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the Common Shares represented thereby, and no cash payment in lieu of
fractional shares shall be paid to any such holder pursuant to Section 2.5(7)
until the surrender of such Certificates in accordance with this Section 2.5.
Subject to the effect of applicable laws, following surrender of any such
Certificate, there shall be paid to the holder of the certificate representing
whole Common Shares issued in exchange therefor, without interest, at the time
of such surrender, the amount of any cash payable in lieu of a fractional Common
Share to which such holder is entitled pursuant to Section 2.5(7).

     (7) No Fractional Shares.  Notwithstanding any other provision of this
Agreement, each holder of Common Shares retained pursuant to the Merger who
would otherwise have been entitled to retain a fraction of a Retained Share
(after taking into account all Shares delivered by such holder) shall receive,
in lieu thereof, a cash payment (without interest) equal to such fraction
multiplied by the Cash Price.

     (8) Termination of Escrow Fund.  Promptly following the date which is 180
days after the Effective Time, the Exchange Agent shall deliver to the Surviving
Corporation all cash, Certificates and other documents in its possession
relating to the transactions described in this Agreement, and the Exchange
Agent's duties shall terminate.  Thereafter, each holder of a Certificate
formerly representing a Common Share may surrender such Certificate to the
Surviving Corporation and (subject to applicable abandoned property, escheat and
similar laws) receive in consideration therefor the aggregate Merger
Consideration relating thereto, without any interest or dividends thereon.

     (9) No Liability.  None of MergerCo, the Company or Exchange Agent shall be
liable to any person in respect of any Retained Shares (or dividends or
distributions with respect thereto) or cash from the Exchange Fund or the Common
Shares Trust delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law.  If any Certificates shall not have been
surrendered prior to seven years after the Effective Time (or immediately prior
to such earlier date on which any Retained Shares, any cash in lieu of
fractional Retained Shares or any dividends or distributions with respect to
Common Shares in respect of such

                                       10
<PAGE>
 
Certificate would otherwise escheat to or become property of any Governmental
Entity) any such shares, cash, dividends or distributions in respect of such
Certificate shall, to the extent permitted by applicable law, become the
property of the Surviving Corporation, free and clear of all claims or interest
of any person previously entitled thereto.

     (10) Dissenter's Rights.  Notwithstanding 2.1(3), Common Shares that have
not been voted for adoption of the Merger and the Merger Agreement and with
respect to which appraisal shall have been properly demanded in accordance with
the DGCL ("Dissenting Shares") shall not be converted into the right to receive
the Merger Consideration at or after the Effective Time unless and until the
holder of such Common Shares withdraws his or her demand for such appraisal (in
accordance with the DGCL) or becomes ineligible for such appraisal.  If a holder
of Dissenting Shares shall withdraw (in accordance with the DGCL) his or her
demand for such appraisal or shall become ineligible for such appraisal, then,
as of the Effective Time or the occurrence of such event, whichever last occurs,
such holder's Dissenting Shares shall cease to be Dissenting Shares and shall be
converted into and represent the right to receive the Merger Consideration
without interest.  The Company shall give MergerCo (i) prompt notice of any
written demands for appraisal, withdrawals of demands for appraisal of Common
Shares and any other instruments relating to the DGCL received by the Company
and (ii) the opportunity to participate in all negotiations and proceedings with
respect to demands for appraisal.  The Company will not voluntarily make any
payment with respect to demands for appraisal and will not, except with the
prior written consent of MergerCo, settle or offer to settle any such demands.

     (11) Withholding Rights.  The Surviving Corporation or the Exchange Agent
shall be entitled to deduct and withhold from the Merger Consideration otherwise
payable pursuant to this Agreement to any holder of Common Shares, such amounts
as the Exchange Agent or Surviving Corporation is required to deduct and
withhold with respect to the making of such payment under the Internal Revenue
Code of 1986, as amended (the "Code"), or any provision of state, local or
foreign tax law.  To the extent that amounts are so withheld by Surviving
Corporation or the Exchange Agent, such withheld amounts shall be treated for
all purposes of this Agreement as having been paid to the holder of the Shares
in respect of which such deduction and withholding was made by the Exchange
Agent or the Surviving Corporation.

                                       11
<PAGE>
 
     SECTION 2.6    Stock Transfer Books. At the Effective Time, the stock
transfer books of the Company shall be closed with respect to the Common Shares
and no transfer of Common Shares shall thereafter be made.

     SECTION 2.7    No Further Ownership Rights in Company Common Stock.
The Merger Consideration delivered upon the surrender for exchange of Shares in
accordance with the terms hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to such Shares, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
Shares which were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in this Article 2.

     SECTION 2.8    Lost, Stolen or Destroyed Certificates. In the event any
Certificates shall have been lost, stolen or destroyed, the MergerCo or Exchange
Agent shall issue in exchange for such lost, stolen or destroyed Certificates,
upon the making of an affidavit of that fact by the holder thereof, such Merger
Consideration as may be required pursuant to this Article 2; provided, however,
that MergerCo may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against MergerCo or the Exchange
Agent with respect to the Certificates alleged to have been lost, stolen or
destroyed.

     SECTION 2.9    Taking of Necessary Action; Further Action. Each of MergerCo
and the Company will take all such reasonable and lawful action as may be
necessary or appropriate in order to effectuate the Merger in accordance with
this Agreement as promptly as possible. If, at any time after the Effective
Time, any such further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company and MergerCo, the officers and directors of the
Company and MergerCo immediately prior to the Effective Time are fully
authorized in the name of their respective corporations or otherwise to take,
and will take, all such lawful and necessary action.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company hereby represents and warrants to MergerCo that, except as set
forth in the SEC Reports (as hereafter defined) or in the section of the written
disclosure schedule delivered on or prior to the date hereof by the Company to
MergerCo relating to the correlative section of this Article 3 (the "Company
Disclosure Schedule"):

     SECTION 3.1    Organization and Qualification; Subsidiaries.  The Company
and each of its Subsidiaries (as defined below) is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation, and has full corporate power and authority, directly or
indirectly, to own its properties and assets and to carry on its business as it
is now being conducted. The Company and each of its Subsidiaries is duly
qualified or licensed as a foreign corporation to do business, and is in good
standing, in each jurisdiction where the character of its properties or assets
owned, leased or operated by it or the nature of its activities makes such
qualification or licensing necessary, except where the failure to be so
qualified or licensed will not have a Material Adverse Effect (as defined in
Section 9.3). A true and complete list of all of the Company's Subsidiaries,
together with the jurisdiction of incorporation of each Subsidiary, the
authorized capitalization of each Subsidiary, and the name of each holder of,
and the number of shares of each Subsidiary's outstanding capital stock owned
thereby, is set forth in Section 3.1 of the Company Disclosure Schedule.
"Significant Subsidiary" means a Subsidiary of the Company which is a
"significant subsidiary" (as such term is defined in Rule 1-02 of Regulation S-X
of the SEC) of the Company. Except for the ownership interests set forth in
Section 3.1 of the Company Disclosure Schedule, neither the Company nor any
Subsidiary owns, directly or indirectly, any capital stock or other ownership
interest in any other person. The Company has heretofore furnished to MergerCo
complete and correct copies of the Certificate of Incorporation and the By-laws
of the Company and XTRA, Inc., a Maine corporation which is wholly owned by the
Company. Such certificates of incorporation and by-laws are in full force and
effect and no other organizational documents are applicable to or binding upon
the Company or XTRA, Inc. The Company and its Significant Subsidiaries are not
in violation of any of the provisions of their respective certificates of
incorporation, by-laws or equivalent organizational or governing documents.

obligations hereunder and to carry out the transactions contemplated hereby. The
execution, delivery and the performance of this Agreement and the consummation
of the transactions contemplated hereby by the Company, have been duly
authorized by all necessary corporate action on the part of the Company, subject

     SECTION 1.34    Employee Benefits; ERISA.

     (1)  Schedule 3.19(1) contains a true and complete list of each material
deferred compensation and each other equity compensation plan, program,
agreement or arrangement; each severance or termination pay and other "welfare"
plan, fund or program (within the meaning of Section 3(1) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")); each "pension"
plan, fund or program (within the meaning of Section 3(2) of ERISA); each
employment, termination or severance agreement (other than those requiring the
payment of less than $50,000 per year to any employee or former employee and
less than $500,000 per year in the aggregate to all employees); and each other
employee material benefit plan, fund, program, agreement or arrangement, in each
case, that is sponsored, maintained or contributed to or required to be
contributed to by the Company or by any trade or business, whether or not
incorporated (an "ERISA Affiliate"), that together with the Company would be
deemed a "single employer" within the meaning of Section 4001(b) of ERISA, or to
which the Company or an ERISA Affiliate is party, whether written or oral, for
the benefit of any employee or former employee of the Company or any Subsidiary
(the "Plans").  Neither the Company, any Subsidiary nor any ERISA Affiliate has
any commitment or formal plan, whether legally binding or not, to create any
additional employee benefit plan or 

                                       26
<PAGE>
 
modify or change any existing Plan that would affect any employee or former
employee of the Company or any Subsidiary. No Plan is a "multiemployer plan"
within the meaning of Section 3(37) of ERISA. Each Plan may be terminated at any
time by the Company or the appropriate Subsidiary or ERISA Affiliate.

     (2)  With respect to each Plan, the Company has heretofore delivered to
MergerCo each of the following documents:

                (i) a copy of the Plan and any amendments thereto (or if the
     Plan is not a written Plan, a description thereof);

               (ii) a copy of the two most recent annual reports;

              (iii) a copy of the most recent Summary Plan Description required
     under ERISA with respect thereto;

               (iv) if the Plan is funded through a trust or any third party
     funding vehicle, a copy of the trust or other funding agreement and the
     latest financial statements thereof; and

               (v)  the most recent determination letter received from the
     Internal Revenue Service with respect to each Plan intended to qualify
     under Section 401 of the Internal Revenue Code of 1986, as amended (the
     "Code").

     (3)  Each Plan has been operated and administered in all material respects
in accordance with its terms and applicable law, including but not limited to
ERISA and the Code.  To the knowledge of the Company, each Plan intended to be
"qualified" within the meaning of Section 401(a) of the Code is so qualified and
the trusts maintained thereunder are exempt from taxation under Section 501(a)
of the Code.  To the knowledge of the Company, each Plan intended to satisfy the
requirements of Section 501(c)(9) has satisfied such requirements.  To the
knowledge of the Company, neither the Company or any Subsidiary, any Plan, any
trust created thereunder, nor any trustee or administrator thereof has engaged
in a transaction in connection with which the Company or any Subsidiary, any
Plan, any such trust, or any trustee or administrator thereof, or any party
dealing with any Plan or any such trust could be subject to either a civil
penalty assessed pursuant to Section 409 or 502(i) of ERISA or a tax imposed
pursuant to Section 4975 or 4976 of the Code.

                                       27

benefits (whether or not insured) for employees or former employees of the
Company or any Subsidiary for periods extending beyond their retirement or other
termination of service, other than (i) coverage mandated by applicable law, (ii)
death benefits under any "pension plan," or (iii) benefits the full cost of
which is borne by the current or former employee (or his beneficiary).

     (5)  Except as set forth in Schedule 3.19(5) hereto, the consummation of
the transactions contemplated by this Agreement will not, either alone or in
combination with another event, (i) entitle any current or former employee or
officer of the Company or any ERISA Affiliate to severance pay, unemployment
compensation or any other payment, except as expressly provided in this
Agreement, or (ii) accelerate the time of payment or vesting, or increase the
amount of compensation due any such employee or officer.

     (6)  There are no pending, threatened or anticipated claims by or on behalf
of any Plan, by any employee, former employee or beneficiary covered under any
such Plan, or otherwise involving any such Plan (other than routine claims for
benefits).

"Company"), is entitled to retain and receive in connection with the merger (the
"Merger") of the Company with Wheels MergerCo LLC, a Delaware limited liability
company ("MergerCo"), securities (collectively, the "Securities") of the
Company.  The undersigned acknowledges that the undersigned may be deemed an
"affiliate" of the Company within the meaning of Rule 145 ("Rule 145")
promulgated under the Securities Act of 1933 (the "Act"), although nothing
contained herein should be construed as an admission of such fact.

     If the undersigned were an  affiliate under the Act, the undersigned's
ability to sell, assign or transfer the Securities retained by the undersigned
pursuant to the Merger may be restricted unless such transaction is registered
under the Act or an exemption from such registration is available.  The
undersigned understands that such exemptions are limited and the undersigned has
obtained advice of counsel as to the nature and conditions of such exemptions,
including information with respect to the applicability to the sale of such
securities of Rules 144 and 145(d) promulgated under the Act.

     The undersigned hereby represents to and covenants with the Company that
the undersigned will not sell, assign or transfer any of the Securities retained
by the undersigned pursuant to the Merger except (i) pursuant to an effective
registration statement under the Act, (ii) in conformity with the volume and
other limitations of Rule 145 or (iii) in a transaction which, in the opinion of
independent counsel reasonably satisfactory to the Company or as described in a
"no-action" or interpretive letter from the Staff of the Securities and Exchange
Commission (the "SEC"), is not required to be registered under the Act.

     In the event of a sale or other disposition by the undersigned of
Securities pursuant to Rule 145, the undersigned will supply the Company with
evidence of compliance with such Rule, in the form of a letter in the form of
Annex I hereto.
<PAGE>
 
     The undersigned understands that the Company may instruct its transfer
agent to withhold the transfer of any Securities disposed of by the undersigned,
but that upon receipt of such evidence of compliance the transfer agent shall
effectuate the transfer of the Securities sold as indicated in the letter.

     The undersigned acknowledges and agrees that appropriate legends will be
placed on certificates representing Securities retained by the undersigned in
the Merger or held by a transferee thereof, which legends will be removed by
delivery of substitute certificates upon receipt of an opinion in form and
substance reasonably satisfactory to the Company from independent counsel
reasonably satisfactory to the Company to the effect that such legends are no
longer required for purposes of the Act.

     The undersigned acknowledges that (i) the undersigned has carefully read
this letter and understands the requirements hereof and the limitations imposed
upon the distribution, sale, transfer or other disposition of Securities and
(ii) the receipt by MergerCo of this letter is an inducement and a condition to
MergerCo's obligations to consummate the Merger.


                                  Very truly yours,

to the terms and conditions of this Agreement, as follows:

          (a)  Voting of Subject Shares for the Merger.  At any meeting of
               ---------------------------------------

Gross and Andrew Africk, each in his individual capacity as an officer of
MergerCo and to any individual who shall succeed to any such officer of
MergerCo, a proxy to vote the Subject Shares as indicated in Sections 3(a) and
3(b) above.  The Stockholder agrees that this proxy shall be irrevocable during
the term of this Agreement and coupled with an interest and each will take such
further action or execute such other instruments as may be necessary to
effectuate the intent of this proxy and hereby revokes any proxy previously
granted by the Stockholder with respect to the Subject Shares.  The proxy

Recapitalization Agreement, to receive cash or stock as consideration in the
Merger and (ii) shall terminate upon the termination of this Agreement pursuant

Stockholder hereby ratifies 

                                       4

and confirms all that the holder of each irrevocable proxy may lawfully do or
cause to be done by virtue hereof. Each such irrevocable proxy is executed and

each of the parties and delivered to the other parties, it being understood that

prevented for any period pursuant to Section 203 of the DGCL from engaging in
any "business combination" (as such terms are defined in Section 203 of the
DGCL), then this Agreement shall be void and unenforceable until such time as
such authorization and approval shall have been duly and validly obtained.

          (a)  Voting of Subject Shares for the Merger.  At any meeting of
               ---------------------------------------                    
stockholders of the Company called to vote upon the Merger and the
Recapitalization Agreement or at any adjournment thereof or in any other
circumstances upon which a vote, consent or other approval with respect to the
Merger and the Recapitalization Agreement is sought, the Stockholder shall vote
(or cause to be voted) the Subject Shares in favor of the Merger, the adoption
by the Company of the Recapitalization Agreement and the approval of the terms
thereof and each of the other transactions contemplated by the Recapitalization
Agreement (provided that the Stockholder shall not be required to vote in favor
or the Recapitalization Agreement or the Merger if the Recapitalization
Agreement has, without the written consent of the Stockholder, been amended in
any manner that is material and adverse to the Stockholder).

          (b)  Voting of Subject Shares Against Competing Proposals.  During the
               ----------------------------------------------------             
term of this Agreement, Stockholder hereby agrees that it will vote any of the
Subject Securities against the approval of any other merger, consolidation, sale
of assets, reorganization, recapitalization, liquidation or winding up of the
Company or any other extraordinary transaction involving the Company or any
matters related to or in connection therewith, or any corporate action relating
to or the consummation of which would either frustrate the purposes of, or
prevent or delay the consummation of, the transactions contemplated by the
Recapitalization Agreement.

          (c)  Proxies.  As security for the agreements of the Stockholder
               -------                                                    
provided for herein, the Stockholder hereby grants to MergerCo and to Michael
Gross and Andrew Africk, each in his individual capacity as an officer of
MergerCo and to any individual who shall succeed to any such officer of
MergerCo, a proxy to vote the Subject Shares as indicated in Sections 3(a) and
3(b) above. The Stockholder agrees that this proxy shall be irrevocable during
the term of this Agreement and coupled with an interest and each will take such
further action or execute such other instruments as may be necessary to
effectuate the intent of this proxy and hereby revokes any proxy previously
granted by the Stockholder with respect to the Subject Shares. The proxy granted
pursuant to this Section 3(c) shall not affect the Stockholder's ability to make
an election, pursuant to the terms and conditions of the Recapitalization
Agreement, to receive cash or stock as consideration in the Merger and (ii)
shall terminate upon the termination of this Agreement pursuant to Section 8.
Each Stockholder hereby affirms that each irrevocable proxy granted pursuant to
this Section 3(c) is given in connection with the execution of the
Recapitalization Agreement, and that each such irrevocable proxy is given to
secure the performance of the duties of the Stockholder under this Agreement.
The Stockholder hereby further affirms that each such irrevocable proxy is
coupled with an interest and may under no circumstances be revoked. The
Stockholder hereby ratifies

                                       4

and confirms all that the holder of each irrevocable proxy may lawfully do or
cause to be done by virtue hereof. Each such irrevocable proxy is executed and
intended to be irrevocable in accordance with the provisions of Section 212(e)
of the DGCL; provided, that each such irrevocable proxy shall terminate upon
termination of this Agreement pursuant to Section 8.

          (d)  Transfer Restrictions.  Prior to the termination of this
               ---------------------                                   
Agreement, the Stockholder agrees not to (i) sell, transfer, pledge, encumber,

distribution or otherwise) (or consent to any of the foregoing) (collectively,
"Transfer"), or enter into any contract, option or other arrangement or
- ---------                                                              
understanding (including any profit sharing arrangement) with respect to the
Transfer of, any of the Subject Shares or any interest therein other than
pursuant to the terms hereof and the Recapitalization Agreement, (ii) enter into
any voting arrangement or understanding, whether by proxy, voting agreement or
otherwise, or (iii) take any action that would make any of its representations
or warranties contained herein untrue or incorrect or have the effect of
preventing or disabling the Stockholder from performing its obligations under
this Agreement.

          (e)  Appraisal Rights.  The Stockholder hereby irrevocably waives any
               ----------------                                                
rights of appraisal with respect to the Merger or rights to dissent from the
Merger that the Stockholder may have.

Stockholder shall not, nor shall it permit any investment banker, financial
advisor, attorney, accountant or other representatives retained by it, to,

the obligations hereunder shall attach to such Stockholder's Subject Shares and
shall be binding upon any person or entity to which legal or beneficial
ownership of such Subject Shares shall pass, whether by operation of law or

Company affecting the Common Stock, or the acquisition of additional shares of
Common Stock or other voting securities of the Company by the Stockholder, the
number of Subject Shares listed in Schedule A beside the name of the Stockholder

Directors of the Company shall not have duly and validly authorized and approved
by all necessary corporate action, this Agreement, the Recapitalization

expected to become an "interested stockholder" with whom the Company would be
prevented for any period pursuant to Section 203 of the DGCL from engaging in
any "business combination" (as such terms are defined in Section 203 of the
DGCL), then this Agreement shall be void and unenforceable until such time as
such authorization and approval shall have been duly and validly obtained.

          3.   Covenants of the Stockholder. Until the termination of this
               ----------------------------                               
Agreement in accordance with Section 8 hereof, the Stockholder agrees, subject
to the terms and conditions of this Agreement, as follows:

          (a)  Voting of Subject Shares for the Merger.  At any meeting of
               ---------------------------------------                    
stockholders of the Company called to vote upon the Merger and the
Recapitalization Agreement or at any adjournment thereof or in any other
circumstances upon which a vote, consent or other approval with respect to the
Merger and the Recapitalization Agreement is sought, the Stockholder shall vote
(or cause to be voted) the Subject Shares in favor of the Merger, the adoption
by the Company of the Recapitalization Agreement and the approval of the terms
thereof and each of the other transactions contemplated by the Recapitalization
Agreement (provided that the Stockholder shall not be required to vote in favor
or the Recapitalization Agreement or the Merger if the Recapitalization
Agreement has, without the written consent of the Stockholder, been amended in
any manner that is material and adverse to the Stockholder).

          (b)  Voting of Subject Shares Against Competing Proposals.  During the
               ----------------------------------------------------             
term of this Agreement, Stockholder hereby agrees that it will vote any of the
Subject Securities against the approval of any other merger, consolidation, sale
of assets, reorganization, recapitalization, liquidation or winding up of the
Company or any other extraordinary transaction involving the Company or any
matters related to or in connection therewith, or any corporate action relating
to or the consummation of which would either frustrate the purposes of, or
prevent or delay the consummation of, the transactions contemplated by the
Recapitalization Agreement.

          (c)  Proxies.  As security for the agreements of the Stockholder
               -------                                                    
provided for herein, the Stockholder hereby grants to MergerCo and to Michael
Gross and Andrew Africk, each in his individual capacity as an officer of
MergerCo and to any individual who shall succeed to any such officer of
MergerCo, a proxy to vote the Subject Shares as indicated in Sections 3(a) and
3(b) above.  The Stockholder agrees that this proxy shall be irrevocable during
the term of this Agreement and coupled with an interest and each will take such
further action or execute such other instruments as may be necessary to
effectuate the intent of this proxy and hereby revokes any proxy previously
granted by the Stockholder with respect to the Subject Shares.  The proxy
granted pursuant to this Section 3(c) shall not affect the Stockholder's ability
to make an election, pursuant to the terms and conditions of the
Recapitalization Agreement, to receive cash or stock as consideration in the
Merger and (ii) shall terminate upon the termination of this Agreement pursuant
to Section 8.  Each Stockholder hereby affirms that each irrevocable proxy
granted pursuant to this Section 3(c) is given in connection with the execution
of the Recapitalization Agreement, and that each such irrevocable proxy is given
to secure the performance of the duties of the Stockholder under this Agreement.
The Stockholder hereby further affirms that each such irrevocable proxy is
coupled with an interest and may under no circumstances be revoked.  The
Stockholder hereby ratifies 

                                       4
<PAGE>
 
and confirms all that the holder of each irrevocable proxy may lawfully do or
cause to be done by virtue hereof.  Each such irrevocable proxy is executed and
intended to be irrevocable in accordance with the provisions of Section 212(e)
of the DGCL; provided, that each such irrevocable proxy shall terminate upon
termination of this Agreement pursuant to Section 8.

          (d)  Transfer Restrictions.  Prior to the termination of this
               ---------------------                                   
Agreement, the Stockholder agrees not to (i) sell, transfer, pledge, encumber,
assign or otherwise dispose of (including by gift or by contribution or
distribution or otherwise) (or consent to any of the foregoing) (collectively,
"Transfer"), or enter into any contract, option or other arrangement or
- ---------                                                              
understanding (including any profit sharing arrangement) with respect to the
Transfer of, any of the Subject Shares or any interest therein other than
pursuant to the terms hereof and the Recapitalization Agreement, (ii) enter into
any voting arrangement or understanding, whether by proxy, voting agreement or
otherwise, or (iii) take any action that would make any of its representations
or warranties contained herein untrue or incorrect or have the effect of
preventing or disabling the Stockholder from performing its obligations under
this Agreement.

          (e)  Appraisal Rights.  The Stockholder hereby irrevocably waives any
               ----------------                                                
rights of appraisal with respect to the Merger or rights to dissent from the
Merger that the Stockholder may have.

              ---------------------                                         
Stockholder shall not, nor shall it permit any investment banker, financial
advisor, attorney, accountant or other representatives retained by it, to,
directly or indirectly, (i) solicit, initiate or encourage (including by way of
furnishing information), or take any other action to facilitate, any inquiries
or the making of any proposal that may lead to an Acquisition Proposal or (ii)
participate in any discussions or negotiations regarding any proposed
Acquisition Proposal.

          (g)  Certain Events.  The Stockholder agrees that this Agreement and
               --------------                                                 
the obligations hereunder shall attach to such Stockholder's Subject Shares and
shall be binding upon any person or entity to which legal or beneficial
ownership of such Subject Shares shall pass, whether by operation of law or
otherwise.  In the event of any stock split, stock dividend, merger,

Company affecting the Common Stock, or the acquisition of additional shares of
Common Stock or other voting securities of the Company by the Stockholder, the
number of Subject Shares listed in Schedule A beside the name of the Stockholder
shall be adjusted appropriately and this Agreement and the obligations hereunder

execute and deliver, or cause to be executed and delivered, such additional or
further consents, proxies, documents and other instruments as MergerCo or the

purpose or effect substantially similar to that of this Agreement on financial
or other terms (with respect to such other stockholder) more favorable than the
terms of this Agreement, the Stockholder will have the right to elect any of the
benefits thereof, as they may be amended or waived from time to time. The
preceding sentences shall not apply to any arrangements entered into with manage
ment of the Company.

interests or obligations hereunder shall be assigned by any of the parties
without the prior written consent of the other parties, except that MergerCo may
assign, in its sole discretion, any or all of its rights, interests and

consent of the other parties hereto, except as may be required by applicable
law, court process or by obligations pursuant to any listing agreement with any
national securities exchange.

          7.   Term; Termination.  This Agreement shall become effective upon

Agreement shall become null and void and have no further effect, except as
otherwise provided herein, immediately following the earliest to occur of (x)

liability for breach of this Agreement.

          8.   Compliance with Rule 144(c).  For a period of two years following
               ---------------------------

               --------------                                                
Sections, such reference shall be to a Section of this Agreement unless
otherwise indicated.  The headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.  Wherever the words "include," "includes" or "including" are
used in this Agreement, they shall be deemed to be followed by the words
"without limitation."

          (d)  Counterparts.  This Agreement may be executed in one or more
               ------------                                                
counterparts, all of which shall be considered one and the same agreement, and
shall become effective when one or more of the counterparts have been signed by
each of the parties and delivered to the other parties, it being understood that
each party need not sign the same counterpart.

          (e)  Governing Law.  This Agreement shall be governed by, and
               -------------                                           
construed in accordance with, the laws of the State of Delaware regardless of
the laws that might otherwise govern under applicable principles of conflicts of
law thereof.

          (f)  Entire Agreement; No Third-Party Beneficiaries.  This Agreement
               ----------------------------------------------

Directors of the Company shall not have duly and validly authorized and approved
by all necessary corporate action, this Agreement, the Recapitalization

expected to become an "interested stockholder" with whom the Company would be
prevented for any period pursuant to Section 203 of the DGCL from engaging in
any "business combination" (as such terms are defined in Section 203 of the
DGCL), then this Agreement shall be void and unenforceable until such time as
such authorization and approval shall have been duly and validly obtained.

              ----------------------------                               
Agreement in accordance with Section 8 hereof, the Stockholder agrees, subject
to the terms and conditions of this Agreement, as follows:

          (a)  Voting of Subject Shares for the Merger.  At any meeting of
               ---------------------------------------                    
stockholders of the Company called to vote upon the Merger and the
Recapitalization Agreement or at any adjournment thereof or in any other

(or cause to be voted) the Subject Shares in favor of the Merger, the adoption
by the Company of the Recapitalization Agreement and the approval of the terms
thereof and each of the other transactions contemplated by the Recapitalization
Agreement (provided that the Stockholder shall not be required to vote in favor
or the Recapitalization Agreement or the Merger if the Recapitalization
Agreement has, without the written consent of the Stockholder, been amended in
any manner that is material and adverse to the Stockholder).

          (b)  Voting of Subject Shares Against Competing Proposals.  During the
               ----------------------------------------------------             
term of this Agreement, Stockholder hereby agrees that it will vote any of the
Subject Securities against the approval of any other merger, consolidation, sale
of assets, reorganization, recapitalization, liquidation or winding up of the
Company or any other extraordinary transaction involving the Company or any
matters related to or in connection therewith, or any corporate action relating
to or the consummation of which would either frustrate the purposes of, or
prevent or delay the consummation of, the transactions contemplated by the
Recapitalization Agreement.

          (c)  Proxies.  As security for the agreements of the Stockholder
               -------                                                    
provided for herein, the Stockholder hereby grants to MergerCo and to Michael
Gross and Andrew Africk, each in his individual capacity as an officer of
MergerCo and to any individual who shall succeed to any such officer of
MergerCo, a proxy to vote the Subject Shares as indicated in Sections 3(a) and
3(b) above.  The Stockholder agrees that this proxy shall be irrevocable during
the term of this Agreement and coupled with an interest and each will take such
further action or execute such other instruments as may be necessary to
effectuate the intent of this proxy and hereby revokes any proxy previously
granted by the Stockholder with respect to the Subject Shares.  The proxy
granted pursuant to this Section 3(c) shall not affect the Stockholder's ability
to make an election, pursuant to the terms and conditions of the
Recapitalization Agreement, to receive cash or stock as consideration in the
Merger and (ii) shall terminate upon the termination of this Agreement pursuant
to Section 8.  Each Stockholder hereby affirms that each irrevocable proxy
granted pursuant to this Section 3(c) is given in connection with the execution
of the Recapitalization Agreement, and that each such irrevocable proxy is given
to secure the performance of the duties of the Stockholder under this Agreement.
The Stockholder hereby further affirms that each such irrevocable proxy is
coupled with an interest and may under no circumstances be revoked.  The
Stockholder hereby ratifies 

                                       4

and confirms all that the holder of each irrevocable proxy may lawfully do or
cause to be done by virtue hereof. Each such irrevocable proxy is executed and
intended to be irrevocable in accordance with the provisions of Section 212(e)
of the DGCL; provided, that each such irrevocable proxy shall terminate upon
termination of this Agreement pursuant to Section 8.

          (d)  Transfer Restrictions.  Prior to the termination of this

"Transfer"), or enter into any contract, option or other arrangement or
- ---------                                                              
understanding (including any profit sharing arrangement) with respect to the
Transfer of, any of the Subject Shares or any interest therein other than
pursuant to the terms hereof and the Recapitalization Agreement, (ii) enter into
any voting arrangement or understanding, whether by proxy, voting agreement or
otherwise, or (iii) take any action that would make any of its representations
or warranties contained herein untrue or incorrect or have the effect of
preventing or disabling the Stockholder from performing its obligations under
this Agreement.

          (e)  Appraisal Rights.  The Stockholder hereby irrevocably waives any
               ----------------                                                
rights of appraisal with respect to the Merger or rights to dissent from the
Merger that the Stockholder may have.

Stockholder shall not, nor shall it permit any investment banker, financial
advisor, attorney, accountant or other representatives retained by it, to,

Company affecting the Common Stock, or the acquisition of additional shares of

number of Subject Shares listed in Schedule A beside the name of the Stockholder

purpose or effect substantially similar to that of this Agreement on financial
or other terms (with respect to such other stockholder) more favorable than the
terms of this Agreement, the Stockholder will have the right to elect any of the
benefits thereof, as they may be amended or waived from time to time. The
preceding sentences shall not apply to any arrangements entered into with 
management of the Company.

XTRA (representing approximately 10% of the ownership in the recapitalized 
company) will be retained by existing holders. Following the merger shares of 
XTRA will not be listed on the NYSE or quoted on the NASDAQ National Market.  
The transaction is intended to qualify as a recapitalization for financial 
reporting purposes.

               The total value of the transaction, including equity and debt, is
approximately $1.9 billion. After the merger, XTRA will be capitalized with $325
million in equity, of which $292.5 million will be provided by the Apollo funds 
and Interpool (through its affiliate, Atlas Capital Partners) and $32.5 million 
will be represented by the retained interest held by existing shareholders of 
XTRA.  Apollo has received commitments from Chase Manhattan Corporation and 
Credit Suisse First Boston to provide the debt financing necessary for the 
transaction.

               It is expected that following the merger transaction, the Apollo
funds and Interpool will own approximately 90% of XTRA; and the existing 
shareholders will own the remaining 10%.  The merger, which is expected to be 
consummated later this year, is subject to customary conditions including the 
approval of XTRA's stockholders, the availability of the contemplated 
financing, the qualification of the transaction as a recapitalization for 
accounting purposes, and the expiration of antitrust waiting periods.  Under the
merger agreement, XTRA has agreed not to declare or pay any dividends prior to 
the merger.

              Stockholders owning approximately 44% of the outstanding shares 
have agreed to vote in favor of the transaction.
