EXPLANATORY NOTE

This Post-Effective Amendment No. 1 to the Registration Statement on Form S-8
(File No. 333-64442) dated June 26, 2001 (the "Original Registration Statement")
is being filed by Chicago Bridge & Iron Company N.V. (the "Registrant") for the
primary purpose of filing Exhibit No. 5, Opinion re Legality, and the Registrant
hereby incorporates by reference in its entirety (except as set forth herein)
the contents of the Original Registration Statement.

PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

         The following documents have been filed by the Registrant with the
Commission and are hereby incorporated by reference in this Registration
Statement:

         (a)  Annual Report on Form 10-K for the fiscal year ended December 31,
              2002.

         (b)  Quarterly Reports on Form 10-Q for the quarters ended March 31,
              2003 and June 30, 2003, respectively;

         (c)  Current Reports on Form 8-K dated January 22, 2003, May 1, 2003,

              2002 to the Registrant's Registration Statement on Form 8-A filed
              with the Commission under Section 12 of the Securities Exchange
              Act of 1934, as amended (the "Exchange Act") including any
              amendments or reports filed for the purpose of updating such
              description.

         All documents and reports filed by the Registrant pursuant to Sections
13(a), 13(c), 14 or 15(d) of the Exchange Act, after the date hereof and prior
to the filing of a post-effective amendment to the Registration Statement which
indicates that the securities offered hereby have been sold, or which
deregisters all such securities remaining unsold, shall also be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof commencing on the respective dates on which such documents are filed.


ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Article 25 of the Registrant's Articles of Association, as amended (the
"Articles of Association") provides that a current or former director or officer
of the Registrant shall be indemnified by the Registrant against:

         (a)  all expenses (including attorneys' fees), judgments, fines and
              amounts paid in settlement, actually and reasonably incurred in
              connection with any litigation or other legal proceeding (other
              than an action by or in the right of the Registrant) brought
              against him by virtue of his position as a director or officer of
              the Registrant if he acted in good faith and in a manner he
              reasonably believed to be in, or not opposed to, the best
              interests of the Registrant, and, with respect to any criminal
              action or proceeding, had no reasonably cause to believe his
              conduct was unlawful or outside of his mandate; and

         (b)  all expenses (including attorneys' fees), judgments, fines and
              amounts paid in settlement, actually and reasonably incurred in
              connection with any action by or in the right of the Registrant
              brought against him by virtue of his position as a director or
              officer of the Registrant if he acted in good faith and in a
              manner he reasonably believed to be in, or not opposed to, the
              best interests of the Registrant, except that no indemnification
              shall be made with respect to any matter as to which such person
              shall have been adjudged to



              be liable for gross negligence or willful misconduct in the
              performance of his duty to the Registrant, unless a court
              determines that, despite such adjudication but in view of all of
              the circumstances, he is fairly and reasonably entitled to
              indemnification of such expenses.

         Notwithstanding the foregoing, to the extent that a director of officer
has been successful, on the merits or otherwise, in defense of any such
litigation, action or claim, he is required to be indemnified by the Registrant
against all expenses (including attorneys' fees) actually and reasonably
incurred in connection therewith. Expenses may be advanced to a director or
officer at his request and upon resolution of the Supervisory Board, provided
that he undertakes to repay the amount advanced if it is ultimately determined
that he is not entitled to indemnification for such expenses. Indemnification is
only required to be made if a majority of Supervisory Directors not a party to
the action or, if all Supervisory Directors are named as partners to the action,
independent legal counsel, or the general meeting of shareholders, determines
that the applicable standard of conduct required for indemnification has been
met.

         Article 25 of the Articles of Association further provides that the
indemnification provided therein is not exclusive of any other right to which a
person seeking indemnification may be entitled under the laws of The Netherlands
(as from time to time amended) or under any agreement, resolution of the general
meeting of shareholders or of the disinterested members of the Supervisory Board
or otherwise.

         Article 25 of the Articles of Association also provides that directors
of the Registrant will not be personally liable to the Registrant or its
shareholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to the
Registrant or its shareholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or knowing violation of law, (iii) for any
transaction from which the director derived an improper personal benefit or (iv)
for personal liability which is imposed by the law of The Netherlands, as from
time to time amended.

                  The Registrant has entered into indemnification agreements
with certain of its directors providing for indemnification similar to that
provided in the Articles of Association. The Registrant has also obtained
officers' and directors' liability insurance in amounts it believes are
reasonable under the circumstances.


ITEM 8. EXHIBITS.

         All the exhibits filed or incorporated by reference in the Original
Registration Statement are incorporated by reference into, and shall be deemed
part of, this Post-Effective Amendment No. 1, except the following, which are
