IFCO Systems N.V.
Strawinskylaan 2001
1077 ZZ   AMSTERDAM
The Netherlands



Ladies and Gentlemen:

We have acted as legal counsel in the Netherlands to IFCO Systems N.V., a
Netherlands company (the "Issuer"), in connection with the filing by the Issuer
under the Securities Act of 1933, as amended, of a registration statement dated
February 2, 2000 on Form F-4 (the "Registration Statement") with the United
States Securities and Exchange Commission, filed in connection with a
combination of the businesses of the Issuer and PalEx, Inc. ("PalEx") in the
manner and on the terms and conditions as set forth in the Amended and Restated
Agreement and Plan of Reorganization dated October 6, 1999 as included in the
Registration Statement (the "Merger Agreement").

In rendering this opinion we have examined and relied upon the following
documents:

(1)  the Registration Statement which includes the Merger Agreement;

(2)  Amendment no. 1 to the Amended and Restated Agreement and Plan of
     Reorganization;

(3)  an excerpt dated the date hereof of the registration of the Company in the
     Trade Register of the Chamber of Commerce of Amsterdam, The Netherlands
     (the "Excerpt");

(4)  a copy of the Deed of Incorporation of the Company (the "Deed of
     Incorporation"), executed on March 31, 1999 which includes the articles of
     association (statuten) of the Company in force on the date hereof (the
     "Articles");

(5)  the proposed amendement of the Articles as included in the Registration
     Statement; and

(6)  a company certificate of even date hereof attached hereto as Annex 1 (the
     "Company Certificate");

and such other documents and such treaties, laws, rules, regulations, and the
like, as we have deemed necessary as a basis for the opinions hereinafter
expressed.


We have assumed:

(i)    the genuineness of all signatures;

(ii)   the authenticity of all the agreements, certificates, and other documents
       submitted to us as originals;

(iii)  the conformity to the originals of all documents submitted to us as
       copies;

(iv)   that a ministerial declaration of non-objection will be received with
       respect to the document referred to under (5) above and that such
       document will be duly and validly executed through a notarial deed prior
       to the issuance of the Shares, substantially in the form as examined by
       us as draft;

(v)    that the resolution to issue the Shares shall have been validly passed
       prior to the issuance of the Shares;

(vi)   that prior to the issuance of Shares the Company shall have made a
       description as referred to in Section 2:94(b)(1) of the Dutch Civil Code
       and an accountant qualified in the Netherlands shall have issued a
       certificate as referred to in Section 2:94(b)(2) of the Dutch Civil Code;
       and

(vii)  that the contents of the Excerpt and the Company Certificate are true and
       complete as of the date hereof.

Based on the foregoing and subject to any factual matters or documents not
disclosed to us in the course of our investigation, and subject to the
qualifications and limitations stated hereafter, we are of the opinion that:

A.   The Company has been duly incorporated and is validly existing as a
     "naamloze vennootschap" (company with limited liability) under the laws of
     The Netherlands.

B.   The Shares, to be issued to PalEx shareholders as contemplated in the
     Registration Statement (the "Shares"), when duly issued and delivered in
     accordance with the provisions of the Merger Agreement and Netherlands law,
     against payment therefor as provided in the Merger Agreement, will be duly
     and validly issued, fully paid and non-assessable.

In rendering the opinions expressed herein, we have, with your approval, relied
without independent investigation as to all matters governed by or involving
conclusions under the federal law of the United States of America and the law of
the State of New York, upon the opinion (including the qualifications,
assumptions and limitations expressed therein) of King & Spalding, United States
counsel to the Company, of even date herewith.

We express no opinion on any law other than the law of The Netherlands as it
currently stands and has been interpreted in published case law of the courts of
The Netherlands as per the date hereof. We express no opinion on any laws of the
European Communities (insofar as not implemented in The Netherlands in statutes
or other regulations of general application).

This opinion is strictly limited to the matters stated herein and may not be
read as extending by implication to any matters not specifically referred to.
Nothing in this opinion should be taken as expressing an opinion in respect of
any representations or warranties, or other information, or any other document
examined in connection with this opinion except as expressly confirmed herein.



We hereby consent to the use of this opinion as an exhibit to the Registration
Statement and to the use of our name under the caption "Legal Matters" contained
in the prospectus which is included in the Registration Statement.

Yours sincerely,

/s/ Stibbe Simont Monahan Duhot P.C.

                                                                February 2, 2000


Stibbe Simont Monahan Duhot
350 Park Avenue, 28th Floor
New York, New York  10022

Ladies and Gentlemen:

     We have acted as special New York counsel to IFCO Systems N.V. ("IFCO
Systems"), in connection with the preparation, execution and delivery of the
Amended and Restated Agreement and Plan of Reorganization, dated as of October
6, 1999 and effective as of March 29, 1999 (the "Merger Agreement"), by and
among IFCO Systems, IFCO Europe Beteiligungs GmbH, MTS Okologistik Verwaltungs
GmbH, IFCO International Network Beteiligungsgesellschaft mbH, Schoeller
Logistics Industries GmbH, Silver Oak Acquisition Corp. and PalEx, Inc.
(collectively, the "Merger Parties").  You have requested this opinion in
connection with the filing by IFCO Systems of a registration statement (the
"Registration Statement") on Form F-4 under the Securities Act of 1933 with the
Securities and Exchange Commission.  The Registration Statement is being filed
in connection with the consummation of the transactions contemplated by the
Merger Agreement.

     In that connection, we have examined counterparts of the Merger Agreement,
executed by the Merger Parties.

     In our examination of the Merger Agreement, we have assumed the genuineness
of all signatures, the due authority of the parties executing the Merger
Agreement and the conformity to the original of the copy of the Merger Agreement
submitted to us. We have also assumed that each of the Merger Parties is duly
incorporated, validly existing and in good standing as a corporation under the
laws of its respective jurisdiction, has taken all steps necessary to execute
the Merger Agreement under the laws of its respective jurisdiction and has duly
executed and delivered, with all necessary power and authority (corporate and
otherwise), the Merger Agreement. As to matters of fact, we have relied solely
upon the document we have examined.

     Based upon the foregoing, and subject to the qualifications set forth
below, we are of the opinion that the Merger Agreement creates a legal, valid
and binding obligation of IFCO Systems enforceable against IFCO Systems in
accordance with its terms.


                                                                               2

           Our opinion is subject to the following qualifications:

           (a) Our opinion expressed above is subject to the effect of any
     applicable bankruptcy, insolvency, reorganization, fraudulent conveyance,
     moratorium or similar law affecting creditors' rights generally.

           (b) Our opinion expressed above is subject to the effect of general
     principles of equity, including (without limitation) concepts of
     materiality, reasonableness, good faith and fair dealing (regardless of
     whether considered in a proceeding in equity or at law).

           (c) We note further that, in addition to the application of equitable
     principles described above, courts have imposed an obligation on
     contracting parties to act reasonably and in good faith in the exercise of
     their contractual rights and remedies, and may also apply public policy
     considerations in limiting the right of parties seeking to obtain
     indemnification under circumstances where the conduct of such parties in
     the circumstances in question is determined to have constituted
     negligence.

           (d) Our opinion expressed above is limited to the laws of the State
     of New York and the Federal laws of the United States, and we do not
     express any opinion herein concerning any other laws.

     This opinion letter speaks only as of the date hereof. We do not assume,
and we expressly disclaim, any responsibility to advise you of any change of law
or fact that may occur after the date of this opinion letter even though such
change may affect the legal analysis, a legal conclusion or any other matter set
forth in or relating to this opinion letter.

     We hereby consent to the use of this opinion as an exhibit to your opinion
that will be filed as an exhibit to the Registration Statement.


                                    Very truly yours,

                                    /s/ King & Spalding
