NINTH AMENDMENT
TO NOTE PURCHASE AND GUARANTEE AGREEMENT
This Ninth Amendment to Note Purchase and Guarantee Agreement (this
“Amendment”), dated as of December 6, 2017, is made by and among CHICAGO BRIDGE
& IRON COMPANY (DELAWARE), a Delaware corporation (the “Company”), CHICAGO
BRIDGE & IRON COMPANY N.V., a corporation incorporated under the laws of The
Netherlands (the “Parent Guarantor” and, together with the Company, the
“Obligors”), and each of the holders of the Notes (as defined below) set forth
on the signature pages to this Amendment (collectively, the “Noteholders”).
RECITALS:
A.    The Obligors and each of the Noteholders have heretofore entered into the
Note Purchase and Guarantee Agreement dated as of December 27, 2012 (as amended
from time to time prior to the date hereof, the “Existing Note Purchase
Agreement” and as amended by this Amendment and as may be further amended,
amended and restated, supplemented or otherwise modified, the “Note Purchase
Agreement”), pursuant to which the Company issued (i) U.S. $150,000,000
aggregate principal amount of its 4.15% Senior Notes, Series A, due December 27,
2017, (ii) U.S. $225,000,000 aggregate principal amount of its 4.57% Senior
Notes, Series B, due December 27, 2019, (iii) U.S. $275,000,000 aggregate

Series D, due December 27, 2024 (as amended from time to time prior to the date
hereof, the “Existing Notes” and as amended and restated pursuant to this
Amendment and as may be further amended, amended and restated, supplemented or
otherwise modified, the “Notes”).
B.     That certain letter to Michael S. Taff, dated August 9, 2017 (the “August
9 Letter”), provided for, among other things, Milestones (as defined therein) in
connection with the sales process for the proposed Tech Business Sale, the
completion of a strategic review and the delivery of certain related information
by the Obligors to the Noteholders. Specifically, Section 1(d) under the heading
“Technology Business Information” established December 8, 2017 as the deadline
by which Obligors are required to select a winning Final Offer (as defined
therein) and execute an asset or equity purchase and sale agreement. In
addition, Section 10.3(b)(4) of the Existing Note Purchase Agreement requires
Obligors to execute definitive purchase and sale documentation in respect of the
Tech Business Sale on or before December 8, 2017. The required date of
satisfaction of the Obligors’ obligations set forth in this Recital shall
collectively be referred to herein as the “December 8 Deadline”.

1

Agreement pursuant to the terms and conditions set forth herein.
