                              EMPLOYMENT AGREEMENT

        Employment Agreement, dated as of June 30, 2000 (this "Agreement"), by

        WHEREAS, the Company desires the Executive to serve as its Chairman and
President, and the Executive desires to serve as the Chairman and President of

                    Non-Competition; Confidential Information

        Section 4.1 Non-Competition.

        (a) From the date hereof until the termination of the Employment Period
subject to extension as set forth below, the "Non-Competition Period"), the
Executive:

                      (i) shall not engage, directly or indirectly, in any
activities whether as employer, proprietor, partner, stockholder (other than the
holder of less than 5% of the stock of a corporation, the securities of which
are traded on a national securities exchange or in the over-the-counter market),
director, officer, employee or otherwise, in competition within the United
States, England and Canada with the Company or any of its affiliates;

                      (ii) shall not solicit, directly or indirectly, any person
who is a customer or supplier of the Company, any of its affiliates or Windward
for the purpose of acquiring, marketing, leasing or selling mobile or fixed
storage containers (the "Company Business"); and

                      (iii) shall not induce or actively attempt to persuade any
employee of the Company, any of its affiliates or Windward to terminate his
employment relationship in order to enter into any competitive employment.

        (b) Except as required by law, the Executive shall not, at any time
during the Non-Competition Period or thereafter, make use of any confidential
information of the Company, Windward or any of their respective affiliates, nor
divulge any trade secrets or proprietary or confidential information of the
Company, Windward or any of their respective affiliates (including, without
limitation, information relating to customers, suppliers, contracts, business
plans and developments, discoveries, processes, products, systems, know-how,
books and records), except to the extent that such information becomes a matter
of public record (other than as a result of disclosure by the Executive), is
published in a newspaper, magazine or other periodical available to the general
public or as Windward may so authorize in writing. When the Executive shall
cease to be employed by the Company, the Executive shall surrender to the
Company or Windward all records and other documents obtained by him or entrusted
to him during the course of his employment hereunder (together with all copies
thereof) which pertain to the business of the Company or Windward or which were
paid for by the Company other than the Executive's counterparts of this
Agreement and employment-related documents referred to herein.

                                       5
<PAGE>

        (c) The parties acknowledge and agree that the current business
arrangement whereby Executive's affiliate Portosan rents storage containers from
the Company and later permits Portosan customers to re-rent such containers to
third party customers, as and to the extent disclosed to the Windward Entities
in the Company Disclosure Schedule to the Merger Agreement (the "Portosan
Transaction") is beneficial to the Company. As a result, the Portosan
Transaction shall not be prohibited by the covenants contained in clauses (i)
and (ii) of Section 4.1(a) above. Executive agrees that he will cause Portosan
to refrain from engaging in any transaction similar to the Portosan Transaction
with any entity other than the Company.

        (d) The covenants contained in clauses (i) and (ii) of Section 4.1(a)
shall apply within all territories in which the Company is actively engaged in
the conduct of business during the Non-Competition Period.

        (e) It is the desire and intent of the parties that the provisions of
Sections 4.1(a) and 4.1(b) shall be enforced to the fullest extent permissible
under the law and public policies applied in each jurisdiction in which
enforcement is sought. Accordingly, if any particular provision of Sections
4.1(a) or 4.1(b) shall be adjudicated to be invalid or unenforceable, such
provision shall be deemed amended to delete therefrom the portion thus
adjudicated to be invalid or unenforceable, such deletion to apply only with
respect to the operation of such provision in the particular jurisdiction in
which such adjudication is made. In addition, should any court determine that
the provisions of Sections 4.1(a) or 4.1(b) shall be unenforceable with respect
to scope, duration or geographic area, such court shall be empowered to
substitute, to the extent enforceable, provisions similar hereto or other
provisions so as to provide to the Company and Windward, to the fullest extent
permitted by applicable law, the benefits intended by Sections 4.1(a) and
4.1(b).

        (f) The covenants contained in Section 4.1(b) shall survive the
conclusion of the Executive's employment by the Company and/or his service as an
officer of the Company.

        (g) If, at any time, the Executive sells or transfers any securities of
the Company to the Company or to any then-current shareholder of the Company, a
subsequent Non-Competition Period shall begin on the effective date of any such
sale or transfer and expire on the fifth anniversary of such effective date;
provided, however, that such subsequent Non-Competition Periods shall not extend
beyond the tenth (10th) anniversary of the date hereof. Each and every provision
of this Agreement applicable to the Executive and the Company during the
original Non-Competition Period shall apply with equal force and effect to the
Executive and the Company during such subsequent Non-Competition Period and any
reference in this Agreement to the "Non-Competition Period" shall be deemed to
include such subsequent Non-Competition Period.

        (h) In the event Executive violates any provision of this Agreement, the
running of the time period of such provisions so violated shall be automatically
suspended upon the date of such violation and shall resume on the date such
violation ceases and all appeals, if any, are resolved.

                                       6

        (i) The Executive acknowledges and agrees that the covenants,
obligations and agreements of the Executive contained herein relate to special,
unique and extraordinary matters and that a violation of any of the terms of
such covenants, obligations or agreements will cause the Company and its
successors irreparable injury for which adequate remedies are not available at
law. In the event of a breach or threatened breach by Executive of any provision
of this Agreement, the Company and its successors, without proving actual
damages, shall be entitled to an injunction (without the requirement to post
bond) restraining Executive from (a) soliciting or interfering with employees,
consultants, independent contractors, customers or suppliers of the Company, its
affiliates or their respective successors, (b) disclosing, in whole or in part,

disclosed, (c) engaging, participating or otherwise being connected with any
arrangement in competition with the Company's Business described in Section 4.1

threatened breach, including without limitation the recovery of damages from
Executive.

        (j) The Executive acknowledges and agrees that he has and will have a

contacts with the principal customers and suppliers of the Company and its
affiliates in the United States and the rest of the world, if any, all of which
constitute valuable goodwill of, and could be used by the Executive to compete
unfairly with, the Company and its affiliates and that (i) the Executive has
obtained confidential and proprietary information and trade secrets concerning
the business and operations of the Company and its affiliates in the United
States and the rest of the world that could be used to compete unfairly with the
Company and its affiliates, (ii) the covenants and restrictions contained herein
are intended to protect the legitimate interests of the Company and its
affiliates in their respective goodwill, trade secrets and other confidential
and proprietary information, and (iii) the Executive desires to be bound by such
covenants and restrictions.

        (k) The Executive represents that his economic means and circumstances
are such that the provisions of this Agreement, including the restrictive
covenants herein, will not prevent him from providing for himself and his family
on a basis satisfactory to him and them.

        (l) If the Executive raises any question as to the enforceability of any
part or terms of this Agreement, including, without limitation, the restrictive
covenants contained herein, the Executive agrees that he will comply fully with
this Agreement unless and until the entry of an award to the contrary.
