 FIRST SUPPLEMENTAL INDENTURE 

FIRST SUPPLEMENTAL INDENTURE dated as of June 14, 2018 (this “First Supplemental Indenture”), among Layne Christensen
Company, a Delaware corporation (the “Company”), Granite Construction Incorporated, a Delaware corporation (“Granite”) solely for purposes of Section 2.02 hereof), and U.S. Bank National Association, a federal
savings bank, as trustee (the “Trustee”) and as collateral agent. 

W I T N E S S E T H: 

WHEREAS, the Company, the Guarantors and the Trustee are parties to an Indenture, dated as of March 2, 2015 (the
“Indenture”), pursuant to which the Company issued its 8.00% Senior Secured Second Lien Convertible Notes (the “Notes”); 

WHEREAS, the Company, Granite, and Lowercase Merger Sub Incorporated, a Delaware corporation and a wholly owned subsidiary of Granite
(“Merger Sub”), entered into an Agreement and Plan of Merger, dated as of February 13, 2018 (the “Merger Agreement”); 

WHEREAS, pursuant to the Merger Agreement and subject to the terms and conditions therein, Merger Sub will merge with and into the Company
(the “Merger” or “Merger Event”), with the Company continuing as the surviving corporation; 
 WHEREAS,
pursuant to the Merger Agreement and subject to the terms and conditions therein, at the effective time of the Merger, each share of common stock (other than shares to be cancelled in accordance with Section 3.01(a) of the Merger Agreement),
par value $0.01 per share, of the Company (the “Layne Common Stock”) issued and outstanding immediately prior to the effective time of the Merger, will be converted into the right to receive 0.27 shares of common stock, par value
$0.01, of Granite (the “Granite Common Stock”) and, if applicable, cash in lieu of fractional shares of Granite Common Stock, as specified in the Merger Agreement; 

WHEREAS, the Merger is permitted under Section 5.01 of the Indenture as a “Reorganization Event” so long as certain
conditions have been met; 
 WHEREAS, pursuant to Section 10.08(a) of the Indenture, following consummation of the Merger, the
Conversion Consideration due upon conversion of any Notes, and the conditions to any such conversion, will be determined in the same manner as if each reference to any number of shares of Layne Common Stock in Article 10 of the Indenture were
instead a reference to the same number of Reference Property Units; 
 WHEREAS, Section 10.08(a) of the Indenture also provides that at
or before the effective date of the Merger Event, the Company and Granite (solely for purposes of Section 2.02 hereof) will execute and deliver to the Trustee a supplemental indenture pursuant to Section 9.03 of the Indenture; 

WHEREAS, in connection with the execution and delivery of this First Supplemental Indenture, the Trustee has received an Officers’
Certificate and an Opinion of Counsel as contemplated by Sections 5.01(d), 9.03, 10.08(b)(ii)(A), 15.03 and 15.04 of the Indenture; and 

  
 2 








 WHEREAS, the Company and Granite have requested that the Trustee execute and deliver this First
Supplemental Indenture and have satisfied all requirements necessary to make this First Supplemental Indenture a valid instrument in accordance with its terms. 

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged,
the Company, Granite (solely for purposes of Section 2.02 hereof) and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders as follows: 

ARTICLE 1 
 DEFINITIONS 

Section 1.01    Definitions. A term defined in the Indenture has the same meaning when used in this First
Supplemental Indenture unless such term is otherwise defined herein or amended or supplemented pursuant to this First Supplemental Indenture. The words “herein,” “hereof,” “hereunder,” and words of similar import refer
to this First Supplemental Indenture as a whole and not to any particular Article, Section or other subdivision hereof. 

“Reference Property Unit” means 0.27 shares of Granite Common Stock and, if applicable, cash in lieu of fractional shares of
Granite Common Stock, as specified in the Merger Agreement. 
 ARTICLE 2 

AMENDMENT OF INDENTURE 

Section 2.01    Conversion Right. The Company expressly agrees that, in accordance with Section 10.08(a)
of the Indenture, each Holder of Notes immediately prior to the effective time of the Merger, will hereafter be entitled to convert, subject to the provisions of Section 10.03(a) of the Indenture, each $1,000 principal amount of such Notes, in
lieu of shares of Layne Common Stock, the number of shares of Granite Common Stock equal to the Conversion Rate in effect at such time; provided that, at and after the effective time of the Merger, any amount otherwise payable in cash for fractional
shares of Granite Common Stock upon conversion of the Notes will continue to be payable as described in Section 10.03 of the Indenture. 

Section 2.02    Delivery of Shares of Granite Common Stock Upon Conversion. Granite shall provide the Company,
free of preemptive rights and free from all taxes, liens and charges with respect to the issuance thereof, a sufficient number of fully paid and non-assessable shares of Granite Common Stock as may be
necessary to deliver from time to time to holders of the Notes as such Notes are presented for conversion in accordance with Article 10 of the Indenture. 

Section 2.03    Adjustments to Conversion Rate. For avoidance of doubt, immediately following the Merger, the
Conversion Rate will be 23.0769 shares of Granite Common Stock per $1,000 principal amount of Notes, subject thereafter to adjustments as set forth in the Indenture. 

Section 2.04    Adjustments to Additional Shares Table. For the avoidance of doubt, immediately following the
Merger, the following table sets forth hypothetical Make-Whole

Fundamental Change Effective Dates, Stock Prices for Granite Common Stock and the number of Additional Shares of Granite Common Stock by which the Conversion Rate will be increased per $1,000
principal amount of Notes for a Holder that converts a Note in connection with a Make-Whole Fundamental Change having such Make-Whole Fundamental Change Effective Date and Stock Price. The following table amends and restates the table in
Section 10.07(d) of the Indenture.
