NOW, THEREFORE, in consideration of the premises and further valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

1.Amendments to Credit Agreement. Subject to the terms and conditions set forth herein:

(a)Section 1.1 of the Credit Agreement is amended by revising the definition of “Eurodollar Base Rate” in its entirety so that after all such revisions, such definition reads as follows:

““Eurodollar Base Rate” means:

(a)    for any Interest Period with respect to a Eurodollar Rate Advance, the rate per annum equal to the London Interbank Offered Rate (“LIBOR”) or a comparable or successor rate, which rate is approved by the Administrative Agent, as published on the applicable Bloomberg screen page (or such other commercially available source providing such quotations as may be designated by the Administrative Agent from time to time) at approximately 11:00 a.m., London time, two (2) Business Days prior to the commencement

of such Interest Period, for Dollar deposits (for delivery on the first day of such Interest Period) with a term equivalent to such Interest Period; and

(b)    for any interest calculation with respect to the Alternate Base Rate on any date, the rate per annum equal to LIBOR, at or about 11:00 a.m., London time determined two (2) Business Days prior to such date for U.S. Dollar deposits with a term of one month commencing that day;

provided that in no event shall such rate be less than 0%; provided, further that to the extent a comparable or successor rate is approved by the Administrative Agent in connection herewith, the approved rate shall be applied to the applicable Interest Period in a manner consistent with market practice; and provided, further that to the extent such market practice is not administratively feasible for the Administrative Agent, such approved rate shall be applied in a manner as otherwise reasonably determined by the Administrative Agent.”

(b)    Section 7.3(a)(ix) of the Credit Agreement is amended by revising such subsection such that after all such revisions, Section 7.3(a)(ix) reads as follows:

“(ix)    (a) Permitted Existing Indebtedness and (b) other Indebtedness, in addition to that referred to elsewhere in this Section 7.3(a), incurred by the Company’s Subsidiaries, provided that no Default or Unmatured Default shall have occurred and be continuing at the date of such incurrence or would result therefrom, and provided further that the aggregate outstanding amount of all Indebtedness incurred by the Company’s Subsidiaries under this clause (ix)(b) shall not at any time exceed $100,000,000;”

(c)    Section 7.3(a) of the Credit Agreement is further amended by (i) removing the phrase “; and” at the end of subsection (xii) and replacing it with “;”, (ii) removing the “.” at the end of subsection (xiii) and replacing it with “; and”, and (iii) adding new subsection (xiv) to read in its entirety as follows:

“(xiv)     Unsecured Indebtedness incurred by any Borrower or any Subsidiary Guarantor and owing to a joint venture in which any Borrower or any Subsidiary Guarantor owns any interest.”

(d)    Section 7.3(c) of the Credit Agreement is amended and restated in its entirety to read as follows:

“(c) Liens. Neither the Company nor any of its Subsidiaries shall directly or indirectly create, incur, assume or permit to exist any Lien on or with respect to any of their respective property or assets except:

(i)    Liens, if any, created by the Loan Documents or otherwise securing the Obligations;

(ii)    Customary Permitted Liens;

(iii)    [reserved];

(iv)    other Liens, including Permitted Existing Liens, (a) securing Indebtedness of the Company (other than Indebtedness of the Company owed to any Subsidiary) and/or (b) securing Indebtedness of the Company’s Subsidiaries as permitted pursuant to Section 7.3(a) and in an aggregate outstanding amount not to exceed five percent (5%) of consolidated tangible assets of the Company and its Subsidiaries at any time;

(v)    Liens on the assets of The Shaw Group Inc. and its Subsidiaries, existing on the Transaction Closing Date and permitted under the Transaction Agreement, provided that such Liens extend only to such assets or proceeds thereof and were not incurred in contemplation of the Shaw Acquisition;

(vi)    prior to the Transaction Closing Date, Liens on the Escrowed Proceeds securing the repayment of the Escrowed Proceeds to the holders of the Notes;

(vii)    as long as the obligations under this Agreement are secured equally and ratably by the same collateral subject to such Liens, Liens securing the other Transaction Facilities (and any Permitted Refinancing thereof); and

(viii)    Liens on pledged cash of the Company and its Subsidiaries required for notional cash pooling arrangements in the ordinary course of business.

In addition, neither the Company nor any of its Subsidiaries shall become a party to any agreement, note, indenture or other instrument, or take any other action, which would prohibit the creation of a Lien on any of its properties or other assets in favor of the Administrative Agent as collateral for the Obligations; provided that (x) any agreement, note, indenture or other instrument in connection with purchase money Indebtedness (including Capitalized Leases) incurred in compliance with the terms of this Agreement may prohibit the creation of a Lien in favor of the Administrative Agent and the Lenders on the items of property obtained with the proceeds of such Indebtedness and (y) the Transaction Facilities (and any Permitted Refinancing thereof) may prohibit the creation of a Lien in favor of the Administrative Agent and the Lenders unless such Indebtedness is secured equally and ratably with the Obligations.”

(e)    The first paragraph only of Section 7.4(a) of the Credit Agreement is amended and restated in its entirety to read as follows:

“(a)    Maximum Leverage Ratio. The Company shall not permit the ratio (the “Leverage Ratio”) of (i) all Adjusted Indebtedness of the Company and its Subsidiaries as of any date of determination (but excluding any Indebtedness permitted under Section 7.03(a)(xiv)) to (ii) EBITDA for the most recently-ended period of four-fiscal quarters for which financial statements were required to be delivered (commencing with the fiscal quarter ended as of September 30, 2013) to be greater than 3.00 to 1.00.”
