such Disposal to the pro rata payment of Senior Indebtedness outstanding under this Agreement and the other Transaction Facilities; provided that (i) in the case of Dispositions permitted by Section 10.3(a)(2)(ii) and consummated

a written offer of prepayment at a price equal to 100% of the principal amount to be prepaid (at par) plus accrued interest to the date of prepayment, and as otherwise more fully set forth in Section 9.14(d) below; provided that

Proceeds of such incurrence or issuance to the pro rata payment of Senior Indebtedness outstanding under this Agreement and the other Transaction Facilities. Such prepayment of the Notes shall be made pursuant to a written offer of prepayment
at a price equal to 100% of the principal amount to be prepaid, accrued interest thereon to the date of prepayment, and the Modified Make-Whole Amount, and as otherwise more fully set forth in Section 9.14(d) below. 

  
 10 

 (c) From and after the Tenth Amendment Effective Date, upon the issuance by the
Parent Guarantor or any of its Subsidiaries of any of its own Capital Stock (other than any issuance of Capital Stock in connection with employee benefit arrangements), the Obligors shall apply 100% of the Net Cash Proceeds of such issuance to the
pro rata payment of Senior Indebtedness outstanding under this Agreement and the other Transaction Facilities. Such prepayment of the Notes shall be made pursuant to a written offer of prepayment at a price equal to 100% of the principal
amount to be prepaid, accrued interest thereon to the date of prepayment, and the Modified Make-Whole Amount, and as otherwise more fully set forth in Section 9.14(d) below.

any Disposition, incurrence of Indebtedness, issuance of Capital Stock or event or claim giving rise to Net Insurance/Condemnation Proceeds as described in this Section 9.14 (a “Prepayment Event”) shall be made on a pro
rata basis based on the Applicable Balance outstanding under the Transaction Facilities as of the Relevant Completion Date (such pro rata portion of Net Cash Proceeds or Net Insurance/Condemnation Proceeds applicable to the Notes, herein
the “Section 9.14 Ratable Amount”). The Obligors shall deposit the Net Cash Proceeds or Net Insurance/Condemnation Proceeds, as applicable, from any such Prepayment Event in a blocked account held with the
Collateral Agent, for the benefit of the Secured Creditors, on the Relevant Completion Date and promptly (and in any event within five (5) Business Days) following the Relevant Completion Date, make a written offer to prepay the Notes in an
aggregate amount equal to the Section 9.14 Ratable Amount, together with accrued interest thereon and the Modified Make-Whole Amount, if applicable, specifying a prepayment date that is not later than 30 days following the closing of the
Prepayment Event, nor earlier than 10 Business Days after the date of such offer. Such offer of prepayment shall be made pro rata among all of the Notes under this Agreement, without regard to series. Following the application of such Net
Cash Proceeds or Net Insurance/Condemnation Proceeds, as applicable, to prepay the Applicable Balances outstanding under the 2015 Term Loan Agreement, the 2013 Revolving Credit Agreement and the 2015 Revolving Credit Agreement but pending the
prepayment of the Notes as contemplated by this Section 9.14, the remaining balance of the Net Cash Proceeds or Net Insurance/Condemnation Proceeds, as applicable, shall be held in such blocked account with the Collateral Agent for the benefit
of the holders of the Notes and the 2015 Notes. If (x) a holder of the Notes or a holder of 2015 Notes declines all or a portion of its pro rata share of such prepayment, or (y) the Applicable Balance allocable to the lenders under
the 2013 Revolving Credit Agreement and the 2015 Revolving Credit Agreement exceeds the Applicable Outstandings thereunder as of the Relevant Completion Date, the amount of such declined proceeds and any

  
 11 

 
such excess as provided in clauses (x) and (y) above, shall be offered on a pro rata basis to holders of the Notes and the 2015 Notes that have accepted such initial offer of
prepayment and the lenders under the other Transaction Facilities based on the Applicable Balances thereof (it being agreed that any such secondary offer may be made concurrently with the initial offer). The failure of any holder to respond to the
initial offer pursuant to this paragraph (d) shall be deemed an acceptance of such offer. Any acceptance (or deemed acceptance) by a holder of such initial prepayment offer shall be deemed to constitute an acceptance of any such
secondary offer. To the extent any Net Cash Proceeds or Net Insurance/Condemnation Proceeds of a Prepayment Event offered to the holders of the Notes for prepayment are ultimately declined for prepayment (after any declined proceeds are re-offered to the holders of Notes and holders of 2015 Notes that have accepted the initial offer of prepayment, as provided above), the amount of such declined proceeds shall be applied by the Obligors to prepay
Senior Indebtedness outstanding under the other Transaction Facilities, as determined by the Company. Proceeds payable to each holder pursuant to Section 9.14 shall be applied, first, to accrued interest on the principal balance being repaid to
the date of payment, second, to the Modified Make-Whole Amount, if any, and finally, to the principal balance of the Notes. Notwithstanding anything to the contrary set forth in this Section 9.14(d), if the aggregate Net Cash Proceeds or the
Net Insurance/Condemnation Proceeds arising from any event or series of related events, as applicable, referred to in this Section 9.14(d) are less than U.S.$10,000,000 (whether payable in one or more installments), the portion of such proceeds
allocable to the Notes and the 2015 Notes shall remain on deposit in the blocked account (provided that no such requirement shall apply unless such Net Cash Proceeds or Net Insurance/Condemnation Proceeds, when aggregated with all other such Net
Cash proceeds and/or Net Insurance/Condemnation proceeds that are or may be required to be applied in prepayment in accordance with this Section 9.14(d) and Section 9.14(d) of the 2015 NPA exceed $250,000, in which case all such proceeds
shall be deposited in such blocked account) until applied to a prepayment of the Notes and the 2015 Notes and the Company shall not be required to make a prepayment offer in respect of the Notes pursuant to this Section 9.14(d) until five
(5) Business Days after the earlier to occur of (A) the amount on deposit in the blocked account being equal to or more than U.S.$25,000,000 (excluding any Net Insurance/Condemnation Proceeds that are permitted to be, and are, reinvested
in accordance with Section 9.14(e)) or (B) 90 days shall have elapsed since the last distribution from the blocked account in respect of the Notes (provided that the Parent Guarantor may, at its option, make such prepayment offer earlier). 

(e) If the Parent Guarantor or any of its Subsidiaries receives any Net Insurance/Condemnation Proceeds, the Company shall
prepay an aggregate principal amount of the Notes and other Senior Indebtedness under the Transaction Facilities equal to 100% of such Net Insurance/Condemnation Proceeds immediately upon receipt thereof by such Person (such prepayments to be made
and applied as set forth in clause (d) above); provided that, 

  
 12 

 (i) except as provided in clause (ii) below, such obligation shall only
apply to Net Insurance/Condemnation Proceeds in excess of $10,000,000 received by any one or more of the Note Parties during the Covenant Relief Period in respect of each individual event or claim giving rise to Net Insurance/Condemnation Proceeds
so long as no Default or Event of Default has occurred and is continuing,

Insurance/Condemnation Proceeds received in respect of damage attributable to Hurricane Harvey to the extent that the aggregate amount of such Net Insurance/Condemnation Proceeds received during the Covenant Relief Period exceeds $67,000,000
(“Hurricane Harvey Excess Proceeds”) so long as no Default or Event of Default has occurred and is continuing, and 

(iii) if, prior to the date any such prepayment is required to be made under this paragraph (e), the Parent Guarantor notifies
the holders of the Notes of its intention to reinvest all or any portion of the Net Insurance/Condemnation Proceeds, other than Hurricane Harvey Excess Proceeds, in assets used or useful in the business (other than cash or Cash Equivalents) of the
Parent Guarantor or any of its Subsidiaries up to a maximum of $25,000,000 in respect of each individual event or claim giving rise to Net Insurance/Condemnation Proceeds (such Net Insurance/Condemnation Proceeds or portion thereof, the
“Eligible Reinvestment Proceeds”), then so long as (a) no Default or Event of Default has occurred and is continuing and (b) such Eligible Reinvestment Proceeds are held in a blocked account opened with the Collateral
Agent, for the benefit of the Secured Creditors, until such time as they are reinvested, the Company shall not be required to make a mandatory prepayment under this clause (iii) in respect of such Eligible Reinvestment Proceeds to the extent
such Eligible Reinvestment Proceeds are so reinvested within 180 days following receipt thereof, or if the Parent Guarantor or any of its Subsidiaries has committed to so reinvest such Eligible Reinvestment Proceeds during such 180-day period and such Eligible Reinvestment Proceeds are so reinvested within 90 days after the expiration of such 180-day period; provided further that, if any Eligible
Reinvestment Proceeds have not been so reinvested prior to the expiration of the applicable period, the Parent Guarantor shall promptly prepay the outstanding principal amount of the Notes and other Indebtedness with the Eligible Reinvestment
Proceeds not so reinvested as set forth in clause (d) above (without regard to the immediately preceding proviso). Any such prepayment of the Notes pursuant to this Section 9.14(e) shall be made pursuant to a written offer of prepayment to
the holders of the Notes at a price equal to 100% of the principal amount to be prepaid (at par) plus accrued interest to the date of prepayment, and as otherwise more fully set forth in Section 9.14(d) above.

 (l) Amendment and
Restatement of Existing Series A Notes. Subject to the terms and conditions set forth herein, effective as of the Tenth Amendment Effective Date: 

(i) The maturity date of the Existing Series A Notes shall be August 31, 2018 and all references to “December 27,
2017” in the Existing Note Purchase Agreement and the Existing Series A Notes shall be deemed to be references to “August 31, 2018.”. 

(ii) All references to the coupon rate applicable to the Existing Series A Notes in the Existing Note Purchase Agreement and
the Existing Notes shall be deemed to be references to the coupon rate established pursuant to clause (iii) of this Section 2.2(l). 

(iii) Each Existing Series A Note shall be, automatically and without any further action, amended and restated in its entirety
to conform to the form of Note attached hereto as Annex 1 or Annex 2, as applicable, except that the registration number, original principal amount, series and payee set forth in each Existing Series A Note shall remain the same. 

  
 15 

 (iv) At the request of any holder of an Existing Series A Note, the Company
shall, within five Business Days of such request, execute and deliver a new Series A Note in the form of Annex 1 hereto, if such holder is listed on Annex 4, Part A hereto, or Annex 2, if such holder is listed on Annex 4, Part B hereto, in exchange
for, and in replacement of, the original of such Existing Series A Note (or, as applicable, in exchange for a customary form of lost note affidavit in respect thereof), registered in the name of such holder, in the aggregate principal amount of the
Existing Series A Note owing to such holder on the Tenth Amendment Effective Date and dated as of the last date on which interest was scheduled to be, and was, paid. All references to the “Notes,” the “Senior Notes, Series A, due
December 27, 2017” or the “Series A Notes” in this Amendment or in the Note Purchase Agreement shall be deemed to include both the Amended and Restated Senior Notes, Series A-1, in the form

All amounts owing by the Company in respect of the Existing Series A Notes (including, without limitation, all accrued and unpaid interest
on the Existing Series A Notes to but excluding the Tenth Amendment Effective Date) shall continue to be owing under, and shall after the Tenth Amendment Effective Date be evidenced by, the Note Purchase Agreement, the Series A-1 Notes and the Series A-2 Notes (without any further action required on the part of any Person), and shall be payable in accordance with the Note Purchase Agreement and the
Series A Notes. 
 Section 2.3 Other Amendments. 

(a) Section 12.1 (Acceleration). The last paragraph of Section 12.1 is hereby amended and restated in its entirety to read as
follows: 
 Upon any Notes becoming due and payable under this Section 12.1, whether automatically or by declaration,
such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including, but not limited to, interest accrued thereon at the Default Rate) and (y) the Make-Whole
Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby
waived; provided, however, that (1) if the Hydra Transaction Closing has not occurred, (2) the Business Combination Agreement has not expired or been terminated and (3) no Bankruptcy Event has occurred, then, so long as all amounts
owing in respect of the Notes are paid in full prior to the occurrence of a Bankruptcy Event, the foregoing reference to Make-Whole Amount shall be deemed to be a reference to Modified Make-Whole Amount and the outstanding Series A-2 Extension Fee Notes, if any, shall be deemed to have been canceled. Each Obligor 

  
 16 

 
acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Obligors (except as herein specifically
provided for) and that the provision for payment of a Make-Whole Amount or Modified Make-Whole Amount by the Obligors in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation
for the deprivation of such right under such circumstances. 
 (b) Section 14.2 (Transfer and Exchange of Notes). The second
sentence of Section 14.2 is hereby amended and restated in its entirety to read as follows: 
 Each such new Note shall be payable to
such Person as such holder may request and shall be substantially in the form of Exhibit 1(a), Exhibit 1(b), Exhibit 1(c) or Exhibit 1(d) to this Agreement, or Annex 1, Annex 2 or Annex 3 to the Tenth Amendment, as applicable. 

(c) Section 15 (Payments on Notes). The following Section 15.3 is hereby added to the Existing Note Purchase Agreement: 

Section 15.3 Modified Make-Whole Amount and Series A-1 Extension
Fee. This Section 15 shall apply to the payment of the Modified Make-Whole Amount and the Series A-1 Extension Fee as if the references herein to “Make-Whole Amount” included
references to “Modified Make-Whole Amount” and “Series A-1 Extension Fee”. 
 (d)

Notwithstanding the foregoing, no changes may be made to Section 9.13 (or any defined term as used therein) without the consent of each
holder of Notes.

(f) Section 24.10 (Parallel Debt). There is hereby added to the Existing Note Purchase Agreement
a new Section 24.10 to read in its entirety as follows: 

  
 17 

 Section 24.10 Parallel Debt. 

(a) Each Obligor hereby irrevocably and unconditionally undertakes to pay to the Collateral Agent amounts equal to any amounts
owing from time to time by such Obligor to any holder of Notes under any Financing Agreement, whether for principal, interest, Make-Whole Amount, Modified Make-Whole Amount, Series A-1 Extension Fee, fees,
expenses or otherwise, as and when those amounts are due. 
 (b) Each Obligor and the Collateral Agent acknowledge that the
obligations of each Obligor under Section 24.10(a) are several and are separate and independent from, and shall not in any way limit or affect, the corresponding obligations of that Obligor to any holder of Notes under any Financing Agreement
(its “Corresponding Debt”) nor shall the amounts for which each Obligor is liable under Section 24.10(a) (its “Parallel Debt”) be limited or affected in any way by its Corresponding Debt provided that: 

(i) the Parallel Debt of each Obligor shall be decreased to the extent that its Corresponding Debt has been irrevocably paid or
(in the case of guarantee obligations) discharged; and 
 (ii) the Corresponding Debt of each Obligor shall be decreased to
the extent that its Parallel Debt has been irrevocably paid or (in the case of guarantee obligations) discharged; and 

(iii) the amount of the Parallel Debt of each Obligor shall at all times be equal to the amount of its Corresponding Debt. 

(c) For the purpose of this Section 24.10, the Collateral Agent acts in its own name. The Collateral granted under any
German Security Agreement to the Collateral Agent to secure the Parallel Debt is granted to the Collateral Agent in its capacity as creditor of the Parallel Debt. 

(d) All moneys received or recovered by the Collateral Agent pursuant to this Section 24.10, and all amounts received or
recovered by the Collateral Agent from or by the enforcement of any German Security Agreement granted to secure the Parallel Debt, shall be applied in accordance with the Intercreditor Agreement. 

(e) Without limiting or affecting the Collateral Agent’s rights against the Note Parties (whether under this
Section 24.10 or under any other provision of the Financing Agreements), each Obligor acknowledges that: 
 (i) nothing
in this Section 24.10 shall impose any obligation on the Collateral Agent to advance any sum to any Note Party or otherwise under any Financing Agreement, except, if applicable, in the Collateral Agent’s capacity as a holder of Notes; and

 (ii) for the purpose of any vote taken under any Financing Agreement, except, if applicable, in the Collateral
Agent’s capacity as a holder of Notes, the Collateral Agent shall not be regarded as owning any Notes or having any participation or commitment therein.  

  
 18 

 (g) Section 24.11 (German Guarantor Limiting
Language). There is hereby added to the Existing Note Purchase Agreement a new Section 24.11 to read in its entirety as follows: 

Section 24.11 German Guarantee Limitations 
  

	 	(a)	To the extent that a guarantee created under this Agreement or any other obligation which qualifies as a “payment” (Zahlung) within the meaning of Sections 30, 31 of the German Limited Liabilities
Company Act (GmbHG) (the “GmbH-Act”) (the “Guarantee”) is granted or incurred by a Guarantor incorporated in Germany as a limited liability company (GmbH)
(each a “German Guarantor” and collectively, “German Guarantors”), currently CB&I Lummus GmbH and CB&I Novolen Technology GmbH, and the Guarantee of the German Guarantor guarantees amounts which are owed by
any current or future direct or indirect shareholders of the German Guarantor or Subsidiaries of such shareholders (with the exception of Subsidiaries which are also Subsidiaries of the German Guarantor), the Guarantee of the German Guarantor shall
be subject to certain limitations as set out in the following paragraphs of this Section. In relation to any other amounts guaranteed, the Guarantee of the German Guarantor remains unlimited. 

 

	 	(b)	Subject to paragraphs (e) and (f) below, the holders agree that the enforcement of the Guarantee shall be limited in relation to any German Guarantor, provided that the German Guarantor is able to demonstrate as
determined pursuant to the procedures set forth in paragraph (e) below that by enforcing the Guarantee (i) its (or, if a parent entity is a German Guarantor, such parent entity’s) net assets (determined in accordance with the
provisions of the German Commercial Code (HGB) (“HGB”)) (such net assets of any German Guarantor or its parent entity, the “Net Assets”) would be caused to fall below its registered share capital
(Stammkapital) or (ii) if the Net Assets were already lower than its registered share capital, such enforcement would cause such amount to be further reduced (Vertiefung der Unterbilanz) if and to the extent such limitation is
necessary to avoid a violation of Section 30 or 31 GmbH-Act (“Limitation on Enforcement” or “Limitation Event”). 

 

	 	(c)	 Paragraph (b) above shall not apply with respect to (i) loans or other financial accommodation made
available to, or bank guarantees issued for the benefit of creditors of, such German Guarantor or a Subsidiary of such German Guarantor by a holder 

  
 19 

	 	
under this Agreement and (ii) amounts due and payable under the Guarantee which relate to funds made available under this Agreement which have been
on-lent to that German Guarantor or any of its Subsidiaries, in each case to the extent that any such on-lending is outstanding at the time of the enforcement of the
Guarantee. For the avoidance of doubt, nothing in this paragraph (c) shall have the effect that such on-lent amounts may be enforced multiple times (no double dip). 

 

	 	(d)	For the purposes of the calculation of Net Assets pursuant to paragraph (b) above, the following balance sheet items shall be adjusted as follows: 

 

	 	(i)	The amount of any increase of the stated share capital (Stammkapital) of the German Guarantor registered after the Tenth Amendment Effective Date without the prior written consent of the holders shall be deducted
from the relevant stated share capital; 

  

	 	(ii)	loans and other liabilities incurred in violation of the provisions of this Agreement shall be disregarded. The cash pool agreement facilitated by Bank Mendes Gans to which the German Guarantors are parties does not
violate any loan provisions; and 

  

	 	(iii)	the amount of non-distributable assets according to paragraph 8 of Section 268 HGB shall not be included in the calculation of Net Assets. 

 

	 	(e)	The Limitation on Enforcement shall only apply if and to the extent that: 

  

	 	(i)	if following notification by the Required Holders of claims raised under the Guarantee, the German Guarantor provides evidence reasonably satisfactory to the Required Holders, including in particular un-audited interim financial statements, within fifteen (15) Business Days (the “Management Determination”) stating: 

 

	 	(A)	the extent to which the enforcement of an unlimited Guarantee would cause the Net Assets of such German Guarantor to fall below its stated share capital or, if the Net Assets were already less than its stated share
capital (Stammkapital), would cause such amount to be further reduced (in each case taking into account the adjustments set out in paragraph (d) above) and thereby lead to a violation of the capital maintenance requirement as set out in
Sections 30, 31 GmbH-Act; 

  
 20 

	 	(B)	up to which amount the enforcement of the Guarantee would comply with the capital requirements as set out in Section 30, 31 GmbH-Act (the “Guarantee Enforcement
Amount”); and 

  

	 	(C)	where the Guarantee is proposed to be enforced against a German Guarantor that is a subsidiary of another German Guarantor, the extent to which the unlimited enforcement of the Guarantee against the subsidiary German
Guarantor would cause a Limitation Event with respect to the parent German Guarantor. 

  

	 	(ii)	If the Required Holders have contested the Management Determination (which they may do within fifteen (15) Business Days of their receipt of the Management Determination) by claiming that (a) no Limitation
Event is to apply or (b) the Guarantee Enforcement Amount could be higher without breaching the capital maintenance requirement as set out in Sections 30, 31 of the GmbH-Act, the German Guarantor shall
have forty-five (45) Business Days from the date the Required Holders have contested the Management Determination to provide to the holders an expert opinion (the “Expert’s Determination”) by one or more legal and/or audit
experts appointed by the German Guarantor (at its own cost and expense), confirming the amount up to which the enforcement of the Guarantee would comply with the capital maintenance requirements pursuant to Sections 30, 31 GmbH-Act (in each case taking into account the adjustments set out in paragraph (d) above). 

  

	 	(f)	If the Required Holders disagree with the Expert’s Determination, the holders shall nevertheless be entitled to enforce the Guarantee up to the amount which is undisputed between themselves and the German
Guarantor. In relation to the amount which is disputed, the amounts determined in the Expert’s Determination shall be (except for manifest error) binding for the German Guarantor and the holders. 

 

	 	(g)	If the German Guarantor claims that the enforcement of the Guarantee would lead to the occurrence of a Limitation Event, then the German Guarantor shall – to the extent lawful and commercially justifiable –
realise at market value any and all of its assets that are shown in its balance sheet with a book value (Buchwert) which is (in the opinion of the Required Holders) significantly lower than their market value and to the extent that such
assets are not necessary for the German Guarantor’s business (nicht betriebsnotwendig), to the extent necessary to satisfy the amounts demanded under the Guarantee. 

  
 21 

	 	(h)	The Limitation on Enforcement does not affect the right of the holders to claim again any outstanding amount at a later point in time, subject always to the operation of the limitation set out above at the time of such
enforcement. 

  

	 	(i)	This Section 24.11 (German Guarantor Limiting Language) shall apply mutatis mutandis (i) if the Guarantee is granted by a Guarantor incorporated in Germany as a limited liability partnership
(GmbH & Co. KG) in relation to the limited liability company as general partner (Komplementär) of such Guarantor and (ii) to any limited liability company incorporated (or limited partnership with a
limited liability company established) in a jurisdiction other than Germany whose centre of main interest (as that term is used in Article 3(1) of The Council of the European Union Regulation No. 2015/848 on Insolvency Proceedings) is in
Germany. 

  

	 	(j)	In addition to the limitations on the enforcement of the Guarantee, it is hereby agreed that the German Guarantor shall have a defence against any claim, enforcement, or other request for performance or requirement to
perform, whether such requirement is based on statute, contract or otherwise, to the extent such claim, enforcement or other performance would result in personal liability for the German Guarantor’s managing director(s) under then applicable
law and any claims arising under the Guarantee shall be limited to the extent of such defence, such that such personal liability would not be incurred. Nothing herein shall nor shall be deemed to prevent the holders from asserting, in a court of law
or otherwise, that the claim, enforcement or other request for performance would not cause the German Guarantor’s managing director(s) to incur any liability, nor shall it prevent the German Guarantor from asserting, in a court of law or
otherwise, to the contrary. 

  

	 	(k)	Should new legislation or jurisprudence of a higher regional court (Oberlandesgericht) or the Federal Court of Justice (Bundesgerichtshof) – including, without limitation, based on proceedings
initiated by the German Guarantor and/or its managing directors (Geschäftsführer) or the Required Holders – being published, entered into and/or come into force after the Tenth Amendment Effective Date and should such law or
court ruling lead to a different legal and/or factual assessment:  

  
 22 

	 	(i)	of the granting of the Guarantee by the German Guarantor, the holders shall, upon the German Guarantor’s managing directors’ (Geschäftsführer) request, enter into good faith negotiations on
possible amendments to this Section 24.11 (German Guarantor Limiting Language) to the extent necessary to avoid the managing directors’ (Geschäftsführer) personal liability resulting from the granting of the
Guarantee (taking into account the initial intention of the limitations set out in this Section 24.11 (German Guarantor Limiting Language) and, including but not limited to, amending reference points for the assessment whether or not a
violation of §§ 30, 31 GmbHG has occurred); or 

  

	 	(ii)	of the enforcement of the Guarantee so that the limitations in this Section 24.11 (German Guarantor Limiting Language) are, are not, or are only partially, required to protect the managing directors
(Geschäftsführer) of the German Guarantor from the risk of personal liability arising from the enforcement of the Guarantee, the German Guarantor shall, upon the Required Holders’ request, enter into good faith negotiations on
possible amendments to this Section 24.11 (German Guarantor Limiting Language) to the extent such provisions are, are not, or are only partially, required anymore to protect the managing directors (Geschäftsführer) of
the German Guarantor from the risk of personal liability arising from the enforcement of the Guarantee. 

  

	 	(l)	Notwithstanding anything to the contrary in this Agreement, this Section 24.11 (German Guarantor Limiting Language) and any rights or obligations arising out of it shall be governed by, and construed in
accordance with, German law.

 Annex 5 

SECTION 17. GERMAN GUARANTEE LIMITATIONS. 
  

	(a)	To the extent that the guarantee created under this Guarantee Agreement or any other obligation which qualifies as a “payment” (Zahlung) within the meaning of Sections 30, 31 of the German Limited
Liabilities Company Act (GmbHG) (the “GmbH-Act”) (the “Guarantee”) is granted or incurred by a Guarantor incorporated in Germany as a limited liability company
(GmbH) (each a “German Guarantor” and collectively, “German Guarantors”), currently CB&I Lummus GmbH and CB&I Novolen Technology GmbH, and the Guarantee of the German Guarantor guarantees amounts
which are owed by any current or future direct or indirect shareholders of the German Guarantor or Subsidiaries of such shareholders (with the exception of Subsidiaries which are also Subsidiaries of the German Guarantor), the Guarantee of the
German Guarantor shall be subject to certain limitations as set out in the following paragraphs of this clause. In relation to any other amounts guaranteed, the Guarantee of the German Guarantor remains unlimited. 

 

	(b)	Subject to paragraphs (e) and (f) below, the holders agree that the enforcement of the Guarantee shall be limited in relation to any German Guarantor, provided that the German Guarantor is able to demonstrate as
determined pursuant to the procedures set forth in paragraph (e) below that by enforcing the Guarantee (i) its (or, if a parent entity is a German Guarantor, such parent entity’s) net assets (determined in accordance with the
provisions of the German Commercial Code (HGB) (“HGB”)) (such net assets of any German Guarantor or its parent entity, the “Net Assets”) would be caused to fall below its registered share capital
(Stammkapital) or (ii) if the Net Assets were already lower than its registered share capital, such enforcement would cause such amount to be further reduced (Vertiefung der Unterbilanz) if and to the extent such limitation is
necessary to avoid a violation of Section 30 or 31 GmbH-Act (“Limitation on Enforcement” or “Limitation Event”). 

 

	(c)	Paragraph (b) above shall not apply with respect to (i) loans or other financial accommodation made available to, or bank guarantees issued for the benefit of creditors of, such German Guarantor or a
Subsidiary of such German Guarantor by a holder under the Note Agreement and (ii) amounts due and payable under the Guarantee which relate to funds made available under the Note Agreement which have been
on-lent to that German Guarantor or any of its Subsidiaries, in each case to the extent that any such on-lending is outstanding at the time of the enforcement of the
Guarantee. For the avoidance of doubt, nothing in this paragraph (c) shall have the effect that such on-lent amounts may be enforced multiple times (no double dip). 

 

	(d)	For the purposes of the calculation of Net Assets pursuant to paragraph (b) above, the following balance sheet items shall be adjusted as follows: 

 

	 	(i)	The amount of any increase of the stated share capital (Stammkapital) of the German Guarantor registered after the date of this Guarantee Agreement without the prior written consent of the holders shall be
deducted from the relevant stated share capital; 

  
 Annex 5-1 

	 	(ii)	loans and other liabilities incurred in violation of the provisions of the Note Agreement shall be disregarded. The cash pool agreement facilitated by Bank Mendes Gans to which the German Guarantors are parties does not
violate any loan provisions; and 

  

	 	(iii)	the amount of non-distributable assets according to paragraph 8 of Section 268 HGB shall not be included in the calculation of Net Assets. 

 

	(e)	The Limitation on Enforcement shall only apply if and to the extent that: 

  

	 	(i)	if following notification by the Required Holders of claims raised under the Guarantee, the German Guarantor provides evidence reasonably satisfactory to the Required Holders, including in particular un-audited interim financial statements, within fifteen (15) Business Days (the “Management Determination”) stating: 

 

	 	(A)	the extent to which the enforcement of an unlimited Guarantee would cause the Net Assets of such German Guarantor to fall below its stated share capital or, if the Net Assets were already less than its stated share
capital (Stammkapital), would cause such amount to be further reduced (in each case taking into account the adjustments set out in paragraph (d) above) and thereby lead to a violation of the capital maintenance requirement as set out in
Sections 30, 31 GmbH-Act; 

  

	 	(B)	up to which amount the enforcement of the Guarantee would comply with the capital requirements as set out in Section 30, 31 GmbH-Act (the “Guarantee Enforcement
Amount”); and 

  

	 	(C)	where the Guarantee is proposed to be enforced against a German Guarantor that is a subsidiary of another German Guarantor, the extent to which the unlimited enforcement of the Guarantee against the subsidiary German
Guarantor would cause a Limitation Event with respect to the parent German Guarantor. 

  

	 	(ii)	If the Required Holders have contested the Management Determination (which they may do within fifteen (15) Business Days of their receipt of the Management Determination) by claiming that (a) no Limitation
Event is to apply or (b) the Guarantee Enforcement Amount could be higher without breaching the capital maintenance requirement as set out in Sections 30, 31 of the GmbH-Act, the German Guarantor shall
have forty-five (45) Business Days from the date the Required Holders have contested the Management Determination to provide to the holders an expert opinion (the “Expert’s Determination”) by one or more legal and/or audit
experts appointed by the German Guarantor (at its own cost and expense), confirming the amount up to which the enforcement of the Guarantee would comply with the capital maintenance requirements pursuant to Sections 30, 31 GmbH-Act (in each case taking into account the adjustments set out in paragraph (d) above). 

  
 Annex 5-2 

	(f)	If the Required Holders disagree with the Expert’s Determination, the holders shall nevertheless be entitled to enforce the Guarantee up to the amount which is undisputed between themselves and the German
Guarantor. In relation to the amount which is disputed, the amounts determined in the Expert’s Determination shall be (except for manifest error) binding for the German Guarantor and the holders. 

 

	(g)	If the German Guarantor claims that the enforcement of the Guarantee would lead to the occurrence of a Limitation Event, then the German Guarantor shall – to the extent lawful and commercially justifiable –
realise at market value any and all of its assets that are shown in its balance sheet with a book value (Buchwert) which is (in the opinion of the Required Holders) significantly lower than their market value and to the extent that such
assets are not necessary for the German Guarantor’s business (nicht betriebsnotwendig), to the extent necessary to satisfy the amounts demanded under the Guarantee. 

 

	(h)	The Limitation on Enforcement does not affect the right of the holders to claim again any outstanding amount at a later point in time, subject always to the operation of the limitation set out above at the time of such
enforcement. 

  

	(i)	This Section 17 (German guarantee limitations) shall apply mutatis mutandis (i) if the Guarantee is granted by a Guarantor incorporated in Germany as a limited liability partnership
(GmbH & Co. KG) in relation to the limited liability company as general partner (Komplementär) of such Guarantor and (ii) to any limited liability company incorporated (or limited partnership with a
limited liability company established) in a jurisdiction other than Germany whose centre of main interest (as that term is used in Article 3(1) of The Council of the European Union Regulation No. 2015/848 on Insolvency Proceedings) is in
Germany. 

  

	(j)	In addition to the limitations on the enforcement of the Guarantee, it is hereby agreed that the German Guarantor shall have a defence against any claim, enforcement, or other request for performance or requirement to
perform, whether such requirement is based on statute, contract or otherwise, to the extent such claim, enforcement or other performance would result in personal liability for the German Guarantor’s managing director(s) under then applicable
law and any claims arising under the Guarantee shall be limited to the extent of such defence, such that such personal liability would not be incurred. Nothing herein shall nor shall be deemed to prevent the holders from asserting, in a court of law
or otherwise, that the claim, enforcement or other request for performance would not cause the German Guarantor’s managing director(s) to incur any liability, nor shall it prevent the German Guarantor from asserting, in a court of law or
otherwise, to the contrary. 

  
 Annex 5-3 

	(k)	Should new legislation or jurisprudence of a higher regional court (Oberlandesgericht) or the Federal Court of Justice (Bundesgerichtshof) – including, without limitation, based on proceedings
initiated by the German Guarantor and/or its managing directors (Geschäftsführer) or the Required Holders – being published, entered into and/or come into force after the date of Amendment No. 10 and should such law or
court ruling lead to a different legal and/or factual assessment: 

  

	 	(i)	of the granting of the Guarantee by the German Guarantor, the holders shall, upon the German Guarantor’s managing directors’ (Geschäftsführer) request, enter into good faith negotiations on
possible amendments to this Section 17 (German guarantee limitations) to the extent necessary to avoid the managing directors’ (Geschäftsführer) personal liability resulting from the granting of the Guarantee
(taking into account the initial intention of the limitations set out in this Section 17 (German guarantee limitations) and, including but not limited to, amending reference points for the assessment whether or not a violation of
§§ 30, 31 GmbHG has occurred); or 

  

	 	(ii)	of the enforcement of the Guarantee so that the limitations in this Section 17 (German guarantee limitations) are, are not, or are only partially, required to protect the managing directors
(Geschäftsführer) of the German Guarantor from the risk of personal liability arising from the enforcement of the Guarantee, the German Guarantor shall, upon the Required Holders’ request, enter into good faith negotiations on
possible amendments to this Section 17 (German guarantee limitations) to the extent such provisions are, are not, or are only partially, required anymore to protect the managing directors (Geschäftsführer) of the German
Guarantor from the risk of personal liability arising from the enforcement of the Guarantee. 

  

	(l)	Notwithstanding anything to the contrary in this Guarantee Agreement, this Section 17 (German guarantee limitations) and any rights or obligations arising out of it shall be governed by, and construed in
accordance with, German law.
