	 	(b)	 Notwithstanding the above, if a Product is not covered by at least one Valid Claim in the country of the
Territory where it is sold, the applicable royalty rate(s) determined in accordance with the principles set forth in Section 4.2.1 a) above will be reduced by [***] for the Net Sales of such Product made in said country. 

For avoidance of doubt, the following example shall illustrate the royalty payment calculation and for hypothetical illustration purposes
only: 
  

	 	•	 	 Determination of the applicable Royalty Rates in accordance with the table above:

  

	 	•	 	 [***] 

  

	 	•	 	 [***]; and

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed. 

	 	
aggregate total Net Sales of said Product in said country of the Territory have been reduced by more than [***] compare to the preceding applicable year, and (ii) such reduction is only
attributable to the presence of a generic product of said Product marketed by a third industrial company on said country of the Territory, then no royalty on Net Sales of said Product in said country of the Territory shall be due by DYNACURE for the
applicable year. 

  

	 	(d)	 Royalty Stacking - In the event that DYNACURE determines, in its reasonable judgment, that it is
necessary to obtain one or more licenses from third parties to research, develop, make, have made, use, import, export, lease, offer to sell, sell, have sold or otherwise exploit a Product in the Field of Exploitation in any country in the Territory
in order to avoid infringement of the patents controlled by any Third Party, the applicable running royalty owed under this Section 4.2.1 for the applicable calendar year shall be reduced by [***] of the sums paid to the Third Party for the
applicable calendar year in consideration for such license. 

  

	4.2.2	 This Product royalty shall be paid on a Product by Product and country by country basis only with respect to
sales of such Product in such country occurring during the Royalty Term; sales of such Product in such country occurring after the end of the Royalty Term shall not give rise to the payment of royalties.

Revenues received by DYNACURE and/or its Affiliates during each calendar year; the applicable percentage shall be determined on a Sublicense by Sublicense basis, based on the Product that has reached the most advanced development status (such
Product being hereinafter referred to as the “Most Advanced Product”) at the time the Sublicense is granted, as follows: 

  

	 	•	 	 [***] of Sublicensing Revenues if the Sublicense enters into force before [***] for the Most Advanced Product;

  

	 	•	 	 [***] of Sublicensing Revenues if the Sublicense enters into force after [***] for the Most Advanced Product but
prior to [***] for the Most Advanced Product; or 

  

	 	•	 	 [***] of Sublicensing Revenues if the Sublicense enters into force after [***] for the Most Advanced Product.

  

	4.3.2	 With respect to options for a Sublicense, the Parties hereby agree that (x) with respect to any
Sublicensing Revenues received by DYNACURE and/or its Affiliates in consideration for the granting by DYNACURE and/or its Affiliates to a Third Party of option rights to obtain a Sublicense under the Licensed Technology, the percentage applicable to

liabilities of DYNACURE have previously been assigned or transferred but which is not a Large Pharma Party (as defined below) (the “DYNACURE Direct Successor”), (ii) pursuant to which [***] (any such Third Party being a
“Large Pharma Party”) as of the date of the change of control of DYNACURE or the DYNACURE Direct Successor (as the case may be) comes to control DYNACURE or the DYNACURE Direct Successor (as the case may be), directly or indirectly,
the notion of control being that of Article L. 233-3 of the French Code of Commerce, or 

  

	 	(b)	 a merger, absorption, acquisition, or any other corporate transaction pursuant to which all of the assets and
liabilities of DYNACURE or the DYNACURE Direct Successor (as the case may be) are assigned or transferred to a Large Pharma Party, where the Large Pharma Party is the surviving entity, 

DYNACURE or, as the case may be, the DYNACURE Direct Successor (or the buyer of DYNACURE or of the DYNACURE Direct Successor in case of
dissolution thereof as a consequence of the First Transformation Event) shall pay to ICM acting on behalf of the Co-Owners, a transformation fee (“Transformation Fee”) in accordance
with the following principles: 
  

	 	•	 	 in the event the First Transformation Event occurs after [***] but before [***], the amount of the
Transformation Fee due to ICM shall be equal to [***] of the updated value of this Agreement as evaluated at the date of occurrence of the First Transformation Event; 

 

	 	•	 	 in the event the First Transformation Event occurs after [***] but before [***], the amount of the
Transformation Fee due to ICM shall be equal to [***] of the updated value of this Agreement as evaluated at the date of occurrence of the First Transformation Event; 

it being however agreed that: 
  

	 	(i)	 in no event shall the amount of a Transformation Fee due to ICM in accordance with the above-mentioned
principles exceed [***], VAT excluded; and that 

  
 17 

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed.

	 	•	 	 by any entity other than (i) DYNACURE (or its buyer in case of dissolution of DYNACURE as a consequence of
the First Transformation Event) or (ii) the DYNACURE Direct Successor (or its buyer in case of dissolution of the DYNACURE Direct Successor as a consequence of the First Transformation Event). 

For the avoidance of doubt, if the First Transformation Event occurs [***], no amount will be due under this Section 4.4. 

In case of disagreement as to the updated value of the Agreement at the date of the First Transformation Event, such value will be determined
by an independent expert jointly selected by DYNACURE or, as applicable, the DYNACURE Direct Successor (or the buyer in case of dissolution thereof as a consequence of the First Transformation Event) and ICM acting on behalf of the Co-Owners. 
 Any transmission of the Agreement by virtue of any event described in (b) above shall be

Liability arising out of any theory of product liability (including actions in the form of tort, warranty, or strict liability) concerning any Product made, used or sold pursuant to any right granted under this Agreement, including any of

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed. 

 
such resulting from the inherent properties of Licensed Materials or out of a use of any Product by any human being regardless of whether such use was contemplated by the Parties, except to the
extent such Liability results from the breach, negligence, or intentional misconduct of any of the Co-Owners. 
  

	6.5	 Indemnification Procedure. An Indemnified Party that intends to claim indemnification
under Section 6.4 above shall promptly notify the Indemnifying Party (either DYNACURE or ICM acting on behalf of the Co-Owners as appropriate) of any Liability or action in respect of which the
Indemnified Party intends to claim such indemnification, and the Indemnifying Party shall have the right to participate in, and, to the extent the Indemnifying Party so desires, assume the defense thereof with counsel selected by the Indemnifying
Party; provided, however, that an Indemnified Party shall have the right to retain its own counsel, with the fees and expenses of such counsel to be paid by the Indemnifying Party, if representation of such Indemnified Party by the counsel retained
by the Indemnifying Party would be inappropriate due to actual or potential differing interests between such Indemnified Party and any other party represented by such counsel in such proceedings. The indemnification obligations of Section 6.4
above shall not apply to amounts paid in settlement of any claim, suit, action, demand or judgment if such settlement is effected without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld. The Indemnified Party,
its employees and agents, shall co-operate fully with the Indemnifying Party and its legal representatives in the investigation of any action, claim or liability covered by indemnification under
Section 6.4 above. 

  

	6.6	 Insurance. DYNACURE shall procure in relation to Product development
activities conducted by DYNACURE or any Affiliates of DYNACURE or Sublicensees under this Agreement, including notably in relation to any clinical trials, and in any case prior to the First Commercial Sale of any Product, and shall maintain
thereafter, a general liability and product liability insurance policy with a reputable insurer or insurers, with a level of coverage consistent with industry practice. DYNACURE shall provide, or cause to be provided, to the Co-Owners written evidence of such insurance promptly upon request of the Co-Owners. 

 

	6.7	 Compliance of Products with Applicable Laws. DYNACURE and its Affiliates and Sublicensees
shall be solely responsible for ensuring that the Products are in compliance with all applicable laws and regulations, and the Co-Owners shall have no responsibility or liability for any damages resulting from
any noncompliance of the Products with applicable laws and regulations. 

  

	7.	 CONFIDENTIALITY 

 

	7.1	 General provisions. 

The Receiving Party shall keep Confidential Information of the other Party(ies) strictly confidential and shall use them solely for the purpose
contemplated by this Agreement (the “Purpose”), except as otherwise agreed in writing by such other Party(ies) (either by DYNACURE or by ICM acting on behalf of the Co-Owners as
appropriate). 

  
 23 

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed. 

 The Receiving Party shall not publish, disseminate or otherwise disclose any Confidential
Information of the other Party(ies), without the prior written consent of the other Party(ies) (consent of either DYNACURE or ICM acting on behalf of the Co-Owners as appropriate), except as otherwise
expressly permitted under this Agreement. In particular, no Party shall publish, disseminate or otherwise disclose any Joint Results, without the prior written consent of DYNACURE and ICM acting on behalf of the
Co-Owners, except as otherwise expressly permitted under this Agreement. 
 The Receiving Party may
disclose specific Confidential Information of the other Party(ies) to its respective officers, directors, employees and those of its Affiliates (and if applicable, subcontractors and Sublicensees), who need to know the same for the Purpose and are
bound by obligations of confidentiality, non-disclosure and restricted use at least as stringent as those set forth herein (collectively, “Representatives”). 

The Receiving Party shall not disclose any Confidential Information of the other Party(ies) to a third party (except to an Affiliate or if
applicable to a subcontractor or a Sublicensee in accordance with the paragraph above), except if previously duly authorized in writing by such other Party(ies) (either by DYNACURE or by ICM acting on behalf of the
Co-Owners as appropriate) to do so or as otherwise expressly permitted under this Agreement, and provided that, in any case, such third party is bound by confidentiality and restricted use obligations no less
restrictive than those set out herein. 
 In any case, the Receiving Party shall remain liable for compliance with any and all provisions of
this Agreement to the extent applicable, by any of its Representatives as well as any other third party to whom it might disclose Confidential Information of the other Party(ies). 

The Receiving Party shall protect Confidential Information of the other Party(ies) in its possession by using the same degree of care, but not
less than a reasonable degree of care, to prevent the unauthorized disclosure or use of such Confidential Information, as that Receiving Party uses to protect its own proprietary information of same importance. 

 

	7.2	 Term. 

The obligations of confidentiality and restricted use set forth in this Article 7 are valid for the whole term of the present Agreement and
shall survive the Expiration/termination of this Agreement, for whatever reason, for a period of [***] following such Expiration/termination. 
  

	7.3	 Exclusions. 

 

	7.3.1	 The confidentiality, non-disclosure and restricted use obligations set
forth in the present Article 7 shall not apply to the Receiving Party with respect to any specific Confidential Information of the other Party(ies) for which the Receiving Party can demonstrate by written proof that such information:

  

	 	•	 	 is or becomes publicly available without breach by the Receiving Party of its obligations under this Article 7;
or 

  
 24 

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed. 

	 	•	 	 is already known by the Receiving Party, free of any restriction as to its use or disclosure, prior to
disclosure, or 

  

	 	•	 	 is received by the Receiving Party from a third party who is lawfully entitled to disclose it and is not under
any obligation to the other Party(ies) to maintain its confidentiality, or 

  

	 	•	 	 has been independently developed by the Receiving Party without reference to, use of or reliance upon the
Confidential Information of the other Party(ies). 

  

	7.3.2	 Notwithstanding the confidentiality, non-disclosure and restricted use
obligations herein, the Receiving Party may make such disclosures of Confidential Information of the other Party(ies) which are required to be disclosed in compliance with applicable law or order of judicial, regulatory or governmental entity,
including without limitation any disclosures required to comply with stock market regulations. 

 Whenever the Receiving
Party becomes aware of any state of facts which would or might result in disclosure of Confidential Information of the other Party(ies) pursuant to this Section 7.3 (b), it shall, if possible, promptly notify such Party(ies) (either DYNACURE or
ICM acting on behalf of the Co-Owners) prior to any such disclosure so that such Party(ies) may seek a protective order or other appropriate remedy and/or waive compliance with the provisions of the present
Agreement. In any event, if the Receiving Party is unable to promptly notify such Party(ies) (either DYNACURE or ICM acting on behalf of the Co-Owners) prior to disclosure or if such protective order or other
remedy is not obtained, or if such Party(ies) (either DYNACURE or ICM acting on behalf of the Co-Owners) waive(s) compliance with the provisions of the present Agreement, the Receiving Party will furnish only
that portion of the Confidential Information of such Party(ies) which it is advised by counsel is legally required and will exercise reasonable efforts to obtain assurance that confidential treatment will be accorded with respect to the Confidential
Information of such Party(ies). 
  

	7.4	 Special provisions. 

The provisions of the present Article 7 may not constitute an obstacle to either: 

 

	 	1.	 the obligation incumbent to the Co-Owners to produce an internal
activity report, provided such disclosure of Confidential Information shall be limited to the personnel of the relevant Co-Owners who need to know the same for the purpose of evaluating such activity report
and who are bound by obligations of confidentiality, non-disclosure and restricted use at least as stringent as those set forth herein, and such Co-Owners ensure that
such communication does not constitute disclosure within the meaning of industrial property legislation. 

  

	 	2.	 the disclosure by DYNACURE of (i) Confidential Information of the
Co-Owners received by it under the present Agreement (including Joint Results), and of (ii) copies of the present Agreement to actual or potential partners, licensees or investors; provided that in each
case the purpose of such disclosure is limited to the 

  
 25 

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed. 

	 	
evaluation of the contemplated transaction and each of the disclosees is subject to obligations of confidentiality and non-use substantially similar to the
obligations of confidentiality and restricted use described in this Article 7. 

  

	 	3.	 the disclosure by DYNACURE, its Affiliates and Sublicensees of Confidential Information of the Co-Owners (including Joint Results) to the extent that such disclosure is expressly authorized by the present Agreement and/or is reasonably necessary to allow the exploitation of the rights granted to DYNACURE and
its Affiliates under this Agreement, provided that DYNACURE, its Affiliates and/or Sublicensees (as appropriate) ensure(s) that all recipients of such Confidential Information are bound by confidentiality provisions no less restrictive than those
set forth herein. 

  

	7.5	 Press Releases and Public Communications. Any declaration or public communication
regarding the signature of the present Agreement or its content shall only be done only with the consent of both Parties. The Parties hereby agree that a press release concerning the signature of this Agreement will be issued following the Signature
Date, the content of which shall be mutually agreed by the Parties in good faith. 

  

	8.	 INTELLECTUAL PROPERTY 

 

	8.1	 Existing Rights. As between the Parties, each Party shall remain the sole owner of any and
all intellectual property rights, including any ownership or property rights in or to the Licensed Technology, owned by it at the Signature Date. 

  

	8.2	 Patent Filing and Prosecution. 

 

	8.2.1	 Filing, prosecution and maintenance of patents claiming Joint Results (the “Joint Patents”)
shall be managed in accordance with the principles set forth in the Collaboration Agreement. 

  

	8.2.2	 Following the Signature Date, DYNACURE shall be responsible for managing the filing, prosecution and
maintenance of all Licensed Patents other than the Joint Patents (the “Other Licensed Patents”), [***]. The Co-Owners shall provide all such assistance, including any documents signed
by the Co-Owners or its personnel or agents, as may be reasonably requested by DYNACURE for the purposes of prosecuting the Other Licensed Patents. DYNACURE shall provide the
Co-Owners with a copy of all material correspondence received from patent authorities in the Territory regarding the Other Licensed Patents, and shall communicate to ICM on behalf of the Co-Owners in a timely manner drafts of any material filings or responses to be made to such patent authorities with respect to such Other Licensed Patents, and shall take into account any reasonable comments
received from ICM on behalf of the Co-Owners within [***] of such communication. 

  
 26 

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed. 

	8.3	 Enforcement of Licensed Patents. 

 

	8.3.1	 Notification. Each Party shall notify the other Party(ies) (either DYNACURE or ICM
on behalf of the Co-Owners) in the event it becomes aware that a Third Party is infringing any Licensed Patent. 

  

	8.3.2	 Control and Disposition of Claims. DYNACURE shall have the initial right but not
the obligation to bring legal action against any such actual or suspected Third Party infringer (or if applicable defend against a patent certification or similar action) (a “Third Party Infringement Claim”). Prior to
bringing or defending such a legal action, DYNACURE shall discuss its intention with ICM acting on behalf of the Co-Owners, and shall make commercially reasonable efforts to consider ICM’s input (acting
on behalf of the Co-Owners) in good faith. 

 If DYNACURE decides not to bring a
Third Party Infringement Claim as contemplated above, it shall promptly notify ICM acting on behalf of the Co-Owners. Upon receipt of such notice of intent to decline action, ICM acting on behalf of the Co-Owners may, but shall not be required to, bring a Third Party Infringement Claim in its own name and [***], provided that the Co-Owners shall not be entitled to bring such
action if in DYNACURE’s reasonable judgment such action may adversely impact the development or commercialization of a Product. 

During the pendency of such Third Party Infringement Claim, the Party responsible for enforcing, or if applicable defending, any such action
(the “Responsible Party”) shall provide the other Party(ies) (either DYNACURE of ICM acting on behalf of the Co-Owners) with all information reasonably requested by such other
Party(ies) (either by DYNACURE of ICM acting on behalf of the Co-Owners) regarding the status of such action. All materials provided by the Responsible Party to the other Party(ies) (either to DYNACURE or ICM
acting on behalf of the Co-Owners as applicable) shall be treated as the Responsible Party’s Confidential Information. In any action or defense initiated by the Responsible Party, the other Party(ies)
(either DYNACURE or ICM acting on behalf of the Co-Owners as applicable) shall be entitled to, and if legally required to shall, join the action, so long as the Responsible Party retains at all times the sole
right to direct and control the action (including the choice of its own counsel). The other Party (either DYNACURE or ICM acting on behalf of the Co-Owners as applicable) is entitled to be independently
represented by counsel of its choice, [***]. 
 Neither Party shall settle, consent to judgment or otherwise voluntarily dispose of the suit
or action without the prior written consent of the other Party(ies) (either consent of DYNACURE or ICM acting on behalf of the Co-Owners as applicable), which consent shall not be unreasonably delayed,
conditioned, or withheld. Such consent shall be granted if the proposed settlement, consent to judgment or other voluntary disposition does not impose any liability on the other Party(ies) (other than liability that is fully satisfied by the
settling Party on behalf of the other Party(ies)) and does not impose any restrictions on the other Party(ies) and does not admit invalidity or unenforceability of any Licensed Patent claims. 

 

	8.3.3	 Costs and Monetary Recovery. Except as specifically set out above, the Responsible Party shall
bear all costs incurred in connection with any Third Party Infringement Claim, 

  
 27 

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed. 

	 	
including the reasonable costs of the other Party(ies) in providing any requested assistance. The proceeds recovered from any such claim shall be first allocated to the reimbursement of each
Party’s out of pocket expenses (including reasonable attorneys’ fees) incurred in connection with such claim. The remaining portion of proceeds shall be [***]. 

 

	8.3.4	 Disclaimer. Nothing in this Agreement shall be construed as obligating any Party to
proceed against a Third Party infringer. 

  

	8.4	 Defence of Third Party Infringement Claims. If the use of the Licensed Technology under
this Agreement results in a claim, suit or proceeding (any of such being a “Claim”) against the Co-Owners or DYNACURE (or their respective Affiliates) alleging patent infringement, the
Party subject to such Claim (either DYNACURE or ICM on behalf of the Co-Owners as applicable) shall promptly notify the other Party(ies) hereto (either DYNACURE or ICM on behalf of the Co-Owners as applicable) in writing setting forth the facts of such claim in reasonable detail. The Party subject to the Claim (either DYNACURE or ICM on behalf of the
Co-Owners as applicable) shall have the exclusive right to defend and control the defense thereof, [***], using counsel of its own choice; provided, however, it shall not enter into any settlement which admits
or concedes that any aspect of the Licensed Patents is invalid or unenforceable without the prior written consent of such other Party(ies) (either consent of DYNACURE or ICM on behalf of the Co-Owners as
applicable). The defending Party shall keep the other Party(ies) hereto (either DYNACURE or ICM on behalf of the Co-Owners as applicable) reasonably informed of all material developments in connection with any
such Claim. For the avoidance of doubt, this Section shall not affect the Parties’ respective indemnification rights and obligations set out in Article 6 above. 

 

	9.	 TERM AND TERMINATION 

 

	9.1	 Term. This Agreement shall become effective as of the Effective Date and, unless
earlier terminated pursuant to the other provisions of this Article 9, shall continue in full force and effect, on a Product by Product and country-by-country basis,
until the end of the Royalty Term in respect thereof. 

 Upon the expiration of the Royalty Term for a given Product in a
given country, the licenses granted to DYNACURE and its Affiliates under this Agreement in such country shall automatically become fully paid up, royalty free, irrevocable, perpetual licenses. 

 

	9.2	 Termination for Cause. In the event that either DYNACURE or any of the Co-Owners shall commit any breach of or default in any of the terms or conditions of this Agreement (the “Defaulting Party”), and also shall fail to remedy such default or breach within [***]
after receipt of written notice thereof, the other (either DYNACURE or ICM on behalf of the Co-Owners as appropriate) may, at its option and in addition to any other remedies which it may have at law or in
equity, terminate this Agreement by sending notice of termination in writing to the Defaulting Party (either to DYNACURE or ICM acting on behalf of the Co-Owners as appropriate) to such effect, and such
termination shall be effective within [***] after receipt of the receipt of such notice. The Defaulting Party may, within this period, supply proof of an impediment owing to force majeure within the

  
 28 

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed. 

	 	
meaning of Article 1218 of the French Civil code. In the latter case (non-fulfilment of an obligation owing to force majeure), the Defaulting Party must
inform the other Party(ies) (either DYNACURE or ICM acting on behalf of the Co-Owners) in accordance with Article 10.4 below and take all necessary steps to limit the consequences, and in the case where the
case of force majeure persists for more than [***], the other Party(ies) (either DYNACURE or ICM acting on behalf of the Co-Owners) may terminate this Agreement earlier by registered-delivery letter.

  

	9.3	 Unilateral Termination by DYNACURE. DYNACURE may terminate this Agreement at any time
without cause with at least [***] prior written notice to ICM acting on behalf of Co-Owners, in particular in the event that DYNACURE should decide not to develop and commercialize any Product.

  

	9.4	 Termination Upon Insolvency or Bankruptcy. Subject to any mandatory provisions of
applicable law, either DYNACURE or ICM on behalf of the Co-Owners may terminate this Agreement if, at any time, the other files in any court or agency, pursuant to any applicable law or regulation, a petition
in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee, or if the other proposes a written agreement of composition or extension of its debts, or if the other is served with an
involuntary petition against it, filed in any insolvency proceeding, and any petition or filing is not be dismissed with [***] after the filing thereof, or if the other proposes or is subject to any dissolution or liquidation. 

 

	9.5	 Rights and Obligations on Expiration or Termination. 

 

	9.5.1	 Termination by either DYNACURE or ICM on behalf of the Co-Owners
pursuant to this Article 9 shall not prejudice any other remedy that a Party might have. Termination of this Agreement for any reason shall not release any Party hereto from any liability which, at the time of such termination, has already accrued
to the other Party(ies) or which is attributable to a period prior to such termination, nor preclude any Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement.

  

	9.5.2	 Upon termination of this Agreement by any Party (but not upon mere Expiration), at ICM’s written request
(acting on behalf of the Co-Owners), DYNACURE shall, at ICM’s sole option (acting on behalf of the Co-Owners), either return to ICM acting on behalf of the Co-Owners or destroy all its supplies of Licensed Materials, and shall cause any supplies of Licensed Materials held by or for its Affiliates or Sublicensees to be returned or destroyed, and, in case of destruction,
shall promptly thereafter confirm such destruction in writing to ICM acting on behalf of the Co-Owners. 

  

	9.5.3	 Upon any termination of this Agreement for any reason (but not upon mere Expiration), DYNACURE, on the one
hand, and the Co-Owners on the other hand, shall promptly return to the other or destroy (with certification of destruction), at the other Party’s sole option (either at the option of DYNACURE, or ICM
acting on behalf of the Co-Owners as appropriate), all Confidential Information (other than Licensed Materials which are subject to Section 9.5.2. above) received from the other Party(ies) (either from
DYNACURE or 

  
 29 

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed. 

	 	
the Co-Owners as appropriate); except one copy of which may be retained in a limited access file (i) for purposes of monitoring its ongoing
confidentiality obligations hereunder, (ii) to comply with any applicable regulatory requirements, and/or (iii) for the purpose of satisfying its obligations and exercising its rights under this Agreement which survive its
Expiration/termination, subject in any case to compliance by such Party(ies) of its(their) confidentiality obligations as set out in Article 7 above. 

  

	9.5.4	 Upon termination of this Agreement for any reason (but not upon mere Expiration), DYNACURE and its Affiliates
and Sublicensees shall cease using have no further right to exploit the Licensed Technology; provided that DYNACURE, its Affiliates and Sublicensees shall be free to continue using and exploiting any element of the Licensed Technology that is part
of the public domain. Notwithstanding the above, DYNACURE and its Affiliates and Sublicensees shall have the right to sell or otherwise dispose of the stock of any Product then on hand during up to [***] following termination, subject to the payment
of royalties on such sale or disposal as provided herein, and provided such sale or disposal does not pose any health risk. 

  

	9.5.5	 The Parties hereby agree that any Sublicense granted to Sublicensees will terminate upon the termination date
of this Agreement. However, the Parties hereby agree that any Sublicensee may, within [***] after the date of termination of this Agreement, deliver to ICM acting on behalf of the Co-Owners a written
undertaking to render to ICM acting on behalf of the Co-Owners any performance, including payment of money, and to comply with all obligations that would have been due by DYNACURE to ICM acting on behalf of
the Co-Owners under this Agreement and to pay all accrued and unpaid payment obligations due to ICM acting on behalf of the Co-Owners under this Agreement in full
(provided that, in respect of Net Sales, the Sublicensee shall only be obligated to pay royalties in respect of its Net Sales and not those of DYNACURE, DYNACURE’s Affiliates or other Sublicensees). In such a case, ICM acting on behalf of the Co-Owners shall for no additional consideration promptly grant a license to such Sublicensee, effective as of the termination date of this Agreement, which shall otherwise be on the terms of this Agreement (adjusted
as may be required, notably to limit the scope – in terms of territory, licensed product and/or nature of license — of the granted license to that of the relevant Sublicense agreement). ICM acting on behalf of the Co-Owners shall not be obligated to grant any such license to a Sublicensee if this Agreement was terminated as a result of a material breach of DYNACURE attributable to such Sublicensee. 

 

	9.6	 Survival. Articles 1, 5, 6, 7, 8, 9 and 10 this Agreement shall survive Expiration and any
termination of this Agreement for any reason. 

  

	10.	 MISCELLANEOUS 

 

	10.1	 Entire Agreement. This Agreement (including its Appendices) constitutes the entire
agreement between the Parties with respect to the subject matter hereof and supersedes all prior agreements, arrangements, dealings or writings between the Parties with respect to the subject matter hereof (including but not limited to the
Collaboration Agreement but only with respect to the grant of license rights granted to DYNACURE and its Affiliates hereunder), as well as any general conditions or similar printed document issued by any

	[***]	 Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such
excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed. 

	 	
Party. In the event of any conflict or inconsistency between the terms of the body of this Agreement and the terms of its Appendices, the terms of the body of this Agreement shall prevail. This
Agreement may not be changed, modified, amended, or supplemented except by a written instrument signed by the Parties hereto. 

  

	10.2	 Further Assurances. Each Party hereto agrees to execute, acknowledge and/or deliver such
further instruments, and to do all other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement. 

  

	10.3	 Force Majeure. If the performance of any part of this Agreement by DYNACURE or the Co-Owners, or of any obligation under this Agreement, is prevented, restricted, interfered with or delayed by an event constituting force majeure as defined in Article 1218 of the French Code Civil, unless
conclusive evidence to the contrary is provided, the Party (either DYNACURE or the Co-Owners as appropriate) so affected shall, upon giving written notice to the other Party(ies) (either to DYNACURE or ICM
acting on behalf of the Co-Owners as appropriate), be excused from such performance to the extent of such prevention, restriction, interference or delay, provided that the affected Party (either DYNACURE or
the Co-Owners as appropriate) shall use its reasonable best efforts to avoid or remove such causes of non-performance and shall continue performance with the utmost
dispatch whenever such causes are removed. When such circumstances arise and persist for a period of at least [***], the Parties shall meet to discuss what, if any, modification of the terms of this Agreement may be required in order to arrive at an
equitable solution. 

  

	10.4	 Notice and Reports. Any notice, request, instruction, order or other document to be given
hereunder by a Party to another Party shall be in writing and delivered either (i) personally, or (ii) by internationally recognized express courier service, return receipt requested, to the following addresses:

 or to such other address as DYNACURE or ICM acting on behalf the Co-Owners shall specify to the other in writing in accordance with the above. 
  

	10.5	 Waiver. The waiver by a Party of a breach by another Party of any provisions contained
herein shall be in writing and shall in no way be construed as a waiver of any succeeding breach of such provision or the waiver of the provision itself. The failure of a Party in any one or more instances to insist upon strict performance of any of
the terms and conditions of this Agreement shall not constitute a waiver or relinquishment, to any extent, of the right to assert or rely upon any such terms or conditions on any future occasion. 

 

	10.6	 Headings. In the event of difficulties of interpretation between any of the headings
preceding the clauses and any one of the clauses, the headings shall be ignored. 

  

	10.7	 Assignment. Neither this Agreement, nor any rights and/or obligations hereunder shall be
assignable by any Party to any Third Party hereto without the prior written consent of DYNACURE or ICM acting on behalf of the Co-Owners as appropriate, which shall not be unreasonably withheld, delayed or
conditioned. Notwithstanding the above, DYNACURE may assign this Agreement, without the prior written consent of the Co-Owners, (i) to any of its Affiliates, and/or (ii) subject to Section 4.4
above (when applicable), to any entity that acquires all or substantially all of the business or assets of DYNACURE which relate to the subject matter of this Agreement, whether by merger, reorganization, acquisition, sale, or otherwise; provided in
each case that the assignee undertakes in writing to ICM acting on behalf of the Co-Owners to comply with all DYNACURE’s obligations under this Agreement. This Agreement shall be binding upon and accrue
to the benefit of the Parties hereto and their successors and any permitted assigns. 

  

	10.8	 Counterparts. The present Agreement may be executed in any number of counterparts, each of
which will be deemed an original, but all of which together will constitute one and the same instrument. Facsimile signatures shall be binding upon the Parties and shall be treated as if originals. 

 

	10.9	 Severability. If any provision of the present Agreement is held to be illegal, invalid or
unenforceable under any applicable present or future law, and if the rights or obligations of any Party hereunder will not be materially and adversely affected thereby, (A) such provision will be fully severable, (B) this Agreement will be
construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (C) the remaining provisions of the present Agreement will remain in full force and effect and will not be affected by the illegal,
invalid or unenforceable provision or by its severance herefrom and (D) in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of the present Agreement, a legal, valid and enforceable provision
which best corresponds to the intention and economical purpose of such illegal, invalid or unenforceable provision. 

  

	10.10	 Relationships of the Parties. Except as otherwise expressly stated in this Agreement,
nothing herein shall be construed to create a relationship of joint venture, agency or other form of representation between the Parties. Except as otherwise expressly stated in this

result of such fluctuations (and no Default or Event of Default shall be deemed to have occurred due to such failure to comply), and (2) in calculating the availability under any basket, ratio or test in connection with any action or
transaction unrelated to such Limited Conditional Transaction following the relevant LCT Test Date and prior to the earlier of the date on which such Limited Condition Transaction is consummated and the date that the definitive agreement or date for
redemption, purchase or repayment specified in an irrevocable notice for such Limited Condition Transaction is terminated, expires or passes, as applicable, without consummation of such Limited Condition Transaction, any such basket, ratio or test
shall be determined or tested giving pro forma effect to such Limited Condition Transaction.

and each such Limited Condition Related Transaction, and (iii) solely with respect to Events of Default under Sections 11.1(a) and 11.(j) hereof, the date of determination of whether any such Event of Default has occurred, is

SECTION 2. CREDIT FACILITIES 
 2.1.
Revolver Commitment. 
 2.1.1. Revolver Loans. On the Closing Date, the “Revolver Loans” and “Revolver
Commitments” (each as defined in the Initial Loan Agreement) held by the Lenders shall be deemed to be Revolver Loans and Revolver Commitments under this Agreement. Each Lender hereby agrees, subject to its Revolver Commitment, on the terms set
forth herein, to make Revolver Loans to Borrowers from time to time through the Commitment Termination Date. The Revolver Loans may be repaid and reborrowed as provided herein. In no event shall Lenders have any obligation to honor a request for a
Revolver Loan if the unpaid balance of Revolver Loans outstanding at such time (including the requested Loan) would exceed the Borrowing Base. 

2.1.2. Revolver Notes. The Revolver Loans made by each Lender and interest accruing thereon shall be evidenced by the records of Agent
and such Lender. At the request of any Lender, Borrowers shall deliver to such Lender a promissory note evidencing its Revolver Loans. 

2.1.3. Use of Proceeds. The proceeds of Revolver Loans shall be used by Borrowers solely (a) to pay fees and transaction
expenses associated with the closing of this credit facility; (b) to pay Obligations in accordance with this Agreement; and (c) for lawful corporate purposes of Borrowers, including working capital. Borrowers shall not, directly or
indirectly, use any Letter of Credit or Loan proceeds, nor use, lend, contribute or otherwise make available any Letter of Credit or Loan proceeds to any Subsidiary, joint venture partner or other Person, (i) to fund any activities of or
business with any Person, or in any Designated Jurisdiction, that, at the time of issuance of the Letter of Credit or funding of the Loan, is the target of any Sanction; (ii) in any manner that would result in a violation of a Sanction by any
Person (including any Secured Party or other individual or entity participating in any transaction); or (iii) for any purpose that would breach the U.S. Foreign Corrupt Practices Act of 1977, UK Bribery Act 2010 or similar law in any
jurisdiction. 

  
 -47- 

 2.1.4. Voluntary Reduction or Termination of Revolver Commitments. 

(a) The Revolver Commitments shall terminate on the Revolver Termination Date, unless sooner terminated in accordance with this Agreement.
Upon at least 5 Business Days’ prior written notice to Agent, Borrowers may, at their option, terminate the Revolver Commitments and this credit facility. Subject to Section 2.1.4(c), any notice of termination given by
Borrowers shall be irrevocable. On the termination date, Borrowers shall make Full Payment of all Obligations. 
 (b) Borrowers may
permanently reduce the Revolver Commitments, on a Pro Rata basis for each Lender, upon at least 5 Business Days’ prior written notice to Agent, which notice shall specify the amount of the reduction and shall be irrevocable once given. Each
reduction (in the aggregate for all Lenders) shall be in a minimum amount of $5,000,000, or an increment of $1,000,000 in excess thereof. 

(c) A notice of termination or reduction of the Revolver Commitments pursuant to this Section 2.1.4 delivered by
Borrowers may state that such notice is conditioned upon the effectiveness of other credit facilities, indentures or similar agreements or other transactions, in which case such notice may be revoked by Borrowers (by notice to the Agent on or prior
to the specified effective date) if such condition is not satisfied. 
 2.1.5. Overadvances. If the aggregate Revolver Loans exceed the
Borrowing Base (“Overadvance”) at any time, the excess amount shall be payable by Borrowers on demand by Agent, but all such Revolver Loans shall nevertheless constitute Obligations secured by the Collateral and entitled to all
benefits of the Loan Documents. Agent may require Lenders to honor requests for Overadvance Loans and to forbear from requiring Borrowers to cure an Overadvance, either if (a) no other Event of Default is known to Agent, as long as (i) the
Overadvance does not continue for more than 30 consecutive days and (ii) the Overadvance is not known by Agent to exceed $25,000,000, or (b) regardless of whether an Event of Default exists, Agent discovers an Overadvance not previously
known by it to exist, as long as from the date of such discovery the Overadvance (i) is not increased by more than $2,500,000, and (ii) does not continue for more than 30 consecutive days. In no event shall Overadvance Loans be required
that would cause the outstanding Revolver Loans and LC Obligations to exceed the aggregate Revolver Commitments. Any funding of an Overadvance Loan or sufferance of an Overadvance shall not constitute a waiver by Agent or Lenders of the Event of
Default caused thereby. In no event shall any Borrower or other Obligor be deemed a beneficiary of this Section nor authorized to enforce any of its terms. 

2.1.6. Protective Advances. Agent shall be authorized, in its discretion, at any time that any conditions in
Section 6 are not satisfied to make Base Rate Revolver Loans (“Protective Advances”) (a) up to an aggregate amount of $25,000,000 outstanding at any time, if Agent deems such Loans necessary or
desirable to preserve or protect Collateral, or to enhance the collectability or repayment of Obligations, as long as such Loans do not cause the outstanding Revolver Loans and LC Obligations to exceed the aggregate Revolver Commitments; or
(b) to pay any other amounts chargeable to Obligors under any Loan Documents, including interest, costs, fees and expenses. Each Lender shall participate in each Protective Advance on a Pro Rata basis. Required Lenders may at any time revoke
Agent’s authority to make further Protective Advances under clause (a) by written notice to Agent. Absent such revocation, Agent’s determination that funding of a Protective Advance is appropriate shall be conclusive. No funding of a
Protective Advance shall constitute a waiver by Agent or Lenders of any Event of Default relating thereto. No Obligor shall be a beneficiary of this Section nor authorized to enforce any of its terms.

  
 -48- 

 2.1.7. Increase in Revolver Commitments. Borrowers may request an increase in
Revolver Commitments from time to time upon notice to Agent (a “Revolver Commitments Increase Event”), as long as (i) the requested increase is in a minimum amount of $10,000,000 and is offered on the same terms as existing Revolver
Commitments, except for a closing fee specified by Agent, (ii) increases under this Section 2.1.7 after the Closing Date do not exceed $150,000,000 in the aggregate and no more than three increases are made,
(iii) no reduction in Revolver Commitments pursuant to Section 2.1.4 has occurred after the Closing Date and prior to the requested increase, (iv) the requested increase does not cause (1) this Agreement to
cease being an “ABL Agreement” pursuant to any Intercreditor Agreement (if then in effect) or enjoy similar rights and benefits under any intercreditor agreement (if any) relating to any Refinancing Debt refinancing or refunding the Senior
Notes, the Term Loan B Facility or any Permitted Secured Debt, or (2) the Revolver Commitments to cease being “Permitted Indebtedness” (or similar term) under the Senior Notes Agreements, the Term Loan B Facility, any Permitted
Secured Debt or under any comparable agreement relating to any Refinancing Debt in respect of the Senior Notes, the Term Loan B Facility or any Permitted Secured Debt, and (v) concurrently with or prior to giving effect to such proposed increase,
the “ABL Cap Amount” (or similar term) set forth in any Intercreditor Agreement (if then in effect) is amended to increase such ABL Cap Amount (or similar term) by 115% of such requested increase. Agent shall promptly notify the Lenders of
the requested increase and, within ten (10) Business Days thereafter, each Lender shall notify Agent if and to what extent such Lender commits to increase its Revolver Commitment. Any Lender not responding within such period shall be
deemed to have declined an increase. If Lenders fail to commit to the full requested increase, Eligible Assignees may issue additional Revolver Commitments and become Lenders hereunder. Agent may allocate, in consultation with Borrower Agent, the
increased Revolver Commitments among committing Lenders and, if necessary, Eligible Assignees. Provided the conditions set forth in Section 6.2 are satisfied, total Revolver Commitments shall be increased by the requested
amount (or such lesser amount committed by Lenders and Eligible Assignees) on a date agreed upon by Agent and Borrower Agent, but no later than 45 days following Borrowers’ increase request. Agent, Obligors, and new and existing Lenders shall
execute and deliver such documents and agreements as Agent deems appropriate to evidence the increase in and allocations of Revolver Commitments. On the effective date of an increase, all outstanding Revolver Loans, LC Obligations and other
exposures under the Revolver Commitments shall be reallocated among Lenders, and settled by Agent if necessary, in accordance with Lenders’ adjusted shares of such Revolver Commitments. In no event shall the provisions of this
Section 2.1.7 or any other provision of this Agreement or any other Loan Document be deemed to create any obligation on the part of any Lender to agree to any increase in the Revolver Commitments and Borrowers agree that
any such increase shall be at the sole option of each Lender. 
 2.2. Letter of Credit Facility. 

2.2.1. Issuance of Letters of Credit. Borrowers acknowledge and agree that, as of the Closing Date, the “Letters of Credit”
listed on Schedule 2.2.1 have been issued and are outstanding under the Initial Loan Agreement. On the Closing Date, such “Letters of Credit” automatically, and without any action on the part of any Person, shall be deemed to
be Letters of Credit issued hereunder for all purposes. Issuing Bank shall issue Letters of Credit from time to time until 30 days prior to the Revolver Termination Date (or until the Commitment Termination Date, if earlier), on the terms set
forth herein, including the following: 

  
 -49- 

 (a) Each Borrower acknowledges that Issuing Bank’s issuance of any Letter of Credit is
conditioned upon Issuing Bank’s receipt of a LC Application with respect to the requested Letter of Credit, as well as such other instruments and agreements as Issuing Bank may customarily require for issuance of a letter of credit of similar
type and amount. Issuing Bank shall have no obligation to issue any Letter of Credit unless (i) Issuing Bank receives a LC Request and LC Application at least three Business Days prior to the requested date of issuance; (ii) each LC
Condition is satisfied; and (iii) if a Defaulting Lender exists, such Lender or Borrowers have entered into arrangements satisfactory to Agent and Issuing Bank to eliminate any Fronting Exposure associated with such Lender. If, in sufficient
time to act, Issuing Bank receives written notice from Agent or Required Lenders that a LC Condition has not been satisfied, Issuing Bank shall not issue the requested Letter of Credit. Prior to receipt of any such notice, Issuing Bank shall not be
deemed to have knowledge of any failure of LC Conditions. 
 (b) Letters of Credit may be requested by a Borrower to support obligations
incurred in the Ordinary Course of Business, or as otherwise approved by Agent. The increase, renewal or extension of any Letter of Credit shall be treated as the issuance of a new Letter of Credit, except that delivery of a new LC Application shall
be required at the discretion of Issuing Bank. 
 (c) Borrowers assume all risks of the acts, omissions or misuses of any Letter of Credit
by the beneficiary. In connection with issuance of any Letter of Credit, none of Agent, Issuing Bank or any Lender shall be responsible for the existence, character, quality, quantity, condition, packing, value or delivery of any goods purported to
be represented by any Documents; any differences or variation in the character, quality, quantity, condition, packing, value or delivery of any goods from that expressed in any Documents; the form, validity, sufficiency, accuracy, genuineness or
legal effect of any Documents or of any endorsements thereon; the time, place, manner or order in which shipment of goods is made; partial or incomplete shipment of, or failure to ship, any goods referred to in a Letter of Credit or Documents; any
deviation from instructions, delay, default or fraud by any shipper or other Person in connection with any goods, shipment or delivery; any breach of contract between a shipper or vendor and a Borrower; errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable, telegraph, telex, telecopy, e-mail, telephone or otherwise; errors in interpretation of technical terms; the misapplication by a beneficiary of any
Letter of Credit or the proceeds thereof; or any consequences arising from causes beyond the control of Issuing Bank, Agent or any Lender, including any act or omission of a Governmental Authority. The rights and remedies of Issuing Bank under the
Loan Documents shall be cumulative. Issuing Bank shall be fully subrogated to the rights and remedies of each beneficiary whose claims against Borrowers are discharged with proceeds of any Letter of Credit. 

(d) In connection with its administration of and enforcement of rights or remedies under any Letters of Credit or LC Documents, Issuing Bank
shall be entitled to act, and shall be fully protected in acting, upon any certification, documentation or communication in whatever form believed by Issuing Bank, in good faith, to be genuine and correct and to have been signed, sent or made by a
proper Person. Issuing Bank may consult with and employ legal counsel, accountants and other experts to advise it concerning its obligations, rights and remedies, and shall be entitled to act upon, and shall be fully protected in any action taken in
good faith reliance upon, any advice given by such experts. Issuing Bank may employ agents and attorneys-in-fact in connection with any matter relating to Letters of
Credit or LC Documents, and shall not be liable for the gross negligence or willful misconduct of agents and attorneys-in-fact selected with reasonable care.

 2.2.2. Reimbursement; Participations. 

(a) If Issuing Bank honors any request for payment under a Letter of Credit, Borrowers shall pay to Issuing Bank, on the same day
(“Reimbursement Date”), the amount paid by Issuing Bank under such Letter of Credit, together with interest at the interest rate for Base Rate Revolver Loans from the Reimbursement Date until payment by Borrowers. The obligation of
Borrowers to reimburse Issuing Bank for any payment made under a Letter of Credit shall be absolute, unconditional, irrevocable, and joint and several, and shall be paid without regard to any lack of validity or enforceability of any Letter of
Credit or the existence of any claim, setoff, defense or other right that Borrowers may have at any time against the beneficiary. Whether or not Borrower Agent submits a Notice of Borrowing, Borrowers shall be deemed to have requested a Borrowing of
Base Rate Revolver Loans in an amount necessary to pay all amounts due Issuing Bank on any Reimbursement Date and each Lender agrees to fund its Pro Rata share of such Borrowing whether or not the Commitments have terminated, an Overadvance exists
or is created thereby, or the conditions in Section 6 are satisfied. It being understood that in the case of a Letter of Credit denominated in an Alternate Currency, the amount of such Letter of Credit to be reimbursed by
the Borrowers under this Section 2.2.2 shall be determined by taking the Dollar Amount of such Letter of Credit. 
 (b) Upon issuance
of a Letter of Credit, each Lender shall be deemed to have irrevocably and unconditionally purchased from Issuing Bank, without recourse or warranty, an undivided Pro Rata interest and participation in all LC Obligations relating to the Letter of
Credit. If Issuing Bank makes any payment under a Letter of Credit and Borrowers do not reimburse such payment on the Reimbursement Date, Agent shall promptly notify Lenders and each Lender shall promptly (within one Business Day) and
unconditionally pay to Agent, for the benefit of Issuing Bank, the Lender’s Pro Rata share of such payment. Upon request by a Lender, Issuing Bank shall furnish copies of any Letters of Credit and LC Documents in its possession at such time. It
being understood that in the case of a Letter of Credit denominated in an Alternate Currency, the amount of such Lender’s payment in respect of such Letter of Credit under this Section 2.2.2 shall be determined by taking the Dollar Amount
of such Letter of Credit. 
 (c) The obligation of each Lender to make payments to Agent for the account of Issuing Bank in connection with
Issuing Bank’s payment under a Letter of Credit shall be absolute, unconditional and irrevocable, not subject to any counterclaim, setoff, qualification or exception whatsoever, and shall be made in accordance with this Agreement under all
circumstances, irrespective of any lack of validity or unenforceability of any Loan Documents; any draft, certificate or other document presented under a Letter of Credit having been determined to be forged, fraudulent, invalid or insufficient in
any respect or any statement therein being untrue or inaccurate in any respect; or the existence of any setoff or defense that any Obligor may have with respect to any Obligations. Issuing Bank does not assume any responsibility for any failure or
delay in performance or any breach by any Borrower or other Person of any obligations under any LC Documents. Issuing Bank does not make to Lenders any express or implied warranty, representation or guaranty with respect to the Collateral, LC
Documents or any Obligor. Issuing Bank shall not be responsible to any Lender for any recitals, statements, information, representations or warranties contained in, or for the execution, validity, genuineness, effectiveness or enforceability of any
LC Documents; the validity, genuineness, enforceability, collectability, value or sufficiency of any Collateral or the perfection of any Lien therein; or the assets, liabilities, financial condition, results of operations, business, creditworthiness
or legal status of any Obligor. 

  
 -51- 

 (d) No Issuing Bank Indemnitee shall be liable to any Lender or other Person for any action
taken or omitted to be taken in connection with any Letter of Credit or LC Document except as a result of its gross negligence or willful misconduct. Issuing Bank may refrain from taking any action with respect to a Letter of Credit until it
receives written instructions from Required Lenders. 
 2.2.3. Cash Collateral. If any LC Obligations, whether or not then due or
payable, shall for any reason be outstanding at any time (a) that an Event of Default exists, (b) that Availability is less than zero, (c) after the Commitment Termination Date, or (d) within 20 Business Days prior to the
Revolver Termination Date, then Borrowers shall, at Issuing Bank’s or Agent’s request, Cash Collateralize the stated amount of all outstanding Letters of Credit and pay to Issuing Bank the amount of all other LC Obligations. Borrowers
shall, on demand by Issuing Bank or Agent from time to time, Cash Collateralize the Fronting Exposure of any Defaulting Lender. In addition, following any such Cash Collateralization, the Agent may request at any time and from time to time
that the relevant Borrower provide additional Cash Collateral to ensure that the amount deposited as Cash Collateral is in an amount equal to 105% of the Fronting Exposure after giving effect to any exchange rate fluctuation with respect to Letters
of Credit denominated in a currency other than Dollars. If Borrowers fail to provide any Cash Collateral as required hereunder, Lenders may (and shall upon direction of Agent) advance, as Revolver Loans, the amount of the Cash Collateral required
(whether or not the Commitments have terminated, an Overadvance exists or the conditions in Section 6 are satisfied). 

2.2.4. Resignation of Issuing Bank. Issuing Bank may resign at any time upon notice to Agent and Borrowers. On and after the effective
date of such resignation, Issuing Bank shall have no obligation to issue, amend, renew, extend or otherwise modify any Letter of Credit, but shall continue to have all rights and other obligations of an Issuing Bank hereunder relating to any Letter
of Credit issued by it prior to such date. Agent shall promptly appoint a replacement Issuing Bank, which (i) accepts such appointment and (ii) as long as no Default or Event of Default exists, shall be reasonably acceptable to Borrowers.

 SECTION 3. INTEREST, FEES AND CHARGES 

3.1. Interest. 

3.1.1. Rates and Payment of Interest. 

(a) The Obligations shall bear interest (i) if a Base Rate Loan, at the Base Rate in effect from time to time, plus the Applicable Margin
for such Base Rate Loan; (ii) if a LIBOR Loan, at LIBOR for the applicable Interest Period, plus the Applicable Margin for LIBOR Loans; and (iii) if any other Obligation (including, to the extent permitted by law, interest not paid when
due), at the Base Rate in effect from time to time, plus the Applicable Margin for the related Base Rate Loans. 
 (b) During an Insolvency
Proceeding with respect to any Borrower, or during any other Event of Default if Agent or Required Lenders in their discretion so elect, Obligations shall bear interest at the Default Rate (whether before or after any judgment). Each Borrower
acknowledges that the cost and expense to Agent and Lenders due to an Event of Default are difficult to ascertain and that the Default Rate is fair and reasonable compensation for this. 

  
 -52- 

 (c) Interest shall accrue from the date a Loan is advanced or Obligation is incurred or
payable, until paid in full by Borrowers. Interest accrued on the Loans shall be due and payable in arrears, (i) on the first day of each month; (ii) on any date of prepayment, with respect to the principal amount of Loans being prepaid;
and (iii) on the Commitment Termination Date. Interest accrued on any other Obligations shall be due and payable as provided in the Loan Documents and, if no payment date is specified, shall be due and payable on demand. Notwithstanding
the foregoing, interest accrued at the Default Rate shall be due and payable on demand. 
 3.1.2. Application of LIBOR to
Outstanding Loans. 
 (a) Borrowers may on any Business Day, subject to delivery of a Notice of Conversion/Continuation, elect to
convert any portion of the Base Rate Loans to, or to continue any LIBOR Loan at the end of its Interest Period as, a LIBOR Loan. During any Default or Event of Default, Agent may (and shall at the direction of Required Lenders) declare that no Loan
may be made, converted or continued as a LIBOR Loan. 
 (b) Whenever Borrowers desire to convert or continue Loans as LIBOR Loans, Borrower
Agent shall give Agent a Notice of Conversion/Continuation, no later than 11:00 a.m. at least three Business Days before the requested conversion or continuation date. Promptly after receiving any such notice, Agent shall notify each Lender thereof.
Each Notice of Conversion/Continuation shall be irrevocable, and shall specify the amount of Loans to be converted or continued, the conversion or continuation date (which shall be a Business Day), and the duration of the Interest Period (which
shall be deemed to be 30 days if not specified). If, upon the expiration of any Interest Period in respect of any LIBOR Loans, Borrowers shall have failed to deliver a Notice of Conversion/Continuation, they shall be deemed to have elected to
convert such Loans into Base Rate Loans. Agent does not warrant or accept responsibility for, nor shall it have any liability with respect to, administration, submission or any other matter related to any rate used in determining LIBOR or with
respect to any alternate or replacement for or successor to any such rate, any Benchmark Replacement Conforming Changes, or the effect of any of the foregoing. 

3.1.3. Interest Periods. In connection with the making, conversion or continuation of any LIBOR Loans, Borrowers shall select an
interest period (“Interest Period”) to apply, which interest period shall be 30, 60, 90 or 180 days; provided, however, that: 

(a) the Interest Period shall begin on the date the Loan is made or continued as, or converted into, a LIBOR Loan, and shall expire on the
numerically corresponding day in the calendar month at its end; 
 (b) if any Interest Period begins on a day for which there is no
corresponding day in the calendar month at its end or if such corresponding day falls after the last Business Day of such month, then the Interest Period shall expire on the last Business Day of such month; and if any Interest Period would otherwise
expire on a day that is not a Business Day, the period shall expire on the next Business Day; and 
 (c) no Interest Period shall extend
beyond the Revolver Termination Date. 

  
 -53- 

 3.1.4. Interest Rate Not Ascertainable. If Agent shall determine that on any date for
determining LIBOR, due to any circumstance affecting the London interbank market, adequate and fair means do not exist for ascertaining such rate on the basis provided herein, then Agent shall immediately notify Borrowers of such determination.
Until Agent notifies Borrowers that such circumstance no longer exists, the obligation of Lenders to make LIBOR Loans shall be suspended, and no further Loans may be converted into or continued as LIBOR Loans. 

3.2. Fees. 

3.2.1. Unused Line Fee. Borrowers shall pay to Agent, for the Pro Rata benefit of Lenders, a fee equal to the Unused Line Fee Rate times
the amount by which the Revolver Commitments exceed the average daily balance of Revolver Loans and stated amount of Letters of Credit during any month. Such fee shall be payable in arrears, on the first day of each month and on the Commitment
Termination Date. 
 3.2.2. LC Facility Fees. Borrowers shall pay (a) to Agent, for the Pro Rata benefit of Lenders, a fee equal
to the Applicable Margin in effect for LIBOR Loans times the average daily stated amount of Letters of Credit, which fee shall be payable monthly in arrears, on the first day of each month; (b) to Agent, for its own account, a fronting fee
equal to 0.125% per annum on the stated amount of each Letter of Credit, which fee shall be payable monthly in arrears, on the first day of each month; and (c) to Issuing Bank, for its own account, all customary charges associated with the
issuance, amending, negotiating, payment, processing, transfer and administration of Letters of Credit, which charges shall be paid as and when incurred. During an Event of Default, the fee payable under clause (a) shall be increased by 2% per
annum. 
 3.2.3. Fee Letters. Borrowers shall pay all fees set forth in any fee letter executed in connection with this Agreement.

 3.3. Computation of Interest, Fees, Yield Protection. All interest, as well as fees and other charges
calculated on a per annum basis, shall be computed for the actual days elapsed, based on a year of 360 days. Each determination by Agent of any interest, fees or interest rate hereunder shall be final, conclusive and binding for all purposes, absent
manifest error. All fees shall be fully earned when due and shall not be subject to rebate, refund or proration. All fees payable under Section 3.2 are compensation for services and are not, and shall not be deemed to be,
interest or any other charge for the use, forbearance or detention of money. A certificate as to amounts payable by Borrowers under Section 3.4, 3.7, 3.9 or 5.9, submitted to Borrower Agent by Agent or the
affected Lender, as applicable, shall be final, conclusive and binding for all purposes, absent manifest error, and Borrowers shall pay such amounts to the appropriate party within 10 days following receipt of the certificate. 

3.4. Reimbursement Obligations. Borrowers shall reimburse Agent for all Extraordinary Expenses. Borrowers shall
also reimburse Agent for all reasonable legal, accounting, appraisal, consulting, and other fees, costs and expenses incurred by it in connection with (a) negotiation and preparation of any Loan Documents, including any amendment or other
modification thereof; (b) administration of and actions relating to any Collateral, Loan Documents and transactions contemplated thereby, including any actions taken to perfect or maintain priority of Agent’s Liens on any Collateral, to
maintain any insurance required hereunder or to verify Collateral; and (c) subject to the limits of Section 10.1.1(b), each inspection, audit or appraisal with respect to any Obligor or Collateral, whether prepared by
Agent’s personnel or a third party. 

  
 -54- 

 
Unless specifically provided for otherwise in this Agreement or any other Loan Document, amounts payable under clauses (a) and (b) of the preceding sentence shall be limited to
out-of-pocket amounts paid by the Agent. All legal, accounting and consulting fees shall be charged to Borrowers by Agent’s professionals at their full hourly
rates, after giving effect to any applicable reduced or alternative fee billing arrangements that Agent may have with such professionals with respect to this transaction. In addition to the Extraordinary Expenses of Agent, upon the occurrence and
during the continuance of an Event Default, Borrowers shall reimburse Lenders for the reasonable and documented fees, charges and disbursements of one counsel (and if necessary, of one local counsel in each other relevant jurisdiction (which may
include a local counsel acting in each of multiple jurisdictions)) for the Lenders, as a whole, in connection with the enforcement, collection or protection of their respective rights under the Loan Documents, including all such expenses incurred
during any workout, restructuring or Insolvency Proceeding; provided, that, notwithstanding anything to the contrary herein, in the event that there is a conflict of interest amongst the Lenders on the one hand or the Agent and the
Lenders on the other hand, the Lenders may engage and be reimbursed for one additional counsel, subject to the foregoing limitations. If, for any reason (including inaccurate reporting on financial statements or a Compliance Certificate), it is
determined that a higher Applicable Margin should have applied to a period than was actually applied, then the proper margin shall be applied retroactively and Borrowers shall immediately pay to Agent, for the Pro Rata benefit of Lenders, an amount
equal to the difference between the amount of interest and fees that would have accrued using the proper margin and the amount actually paid. All amounts payable by Borrowers under this Section shall be due five (5) Business Days after demand.

 3.5. Illegality. If any Lender determines that any Applicable Law has made it unlawful, or that any
Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund LIBOR Loans, or to determine or charge interest rates based upon LIBOR, or any Governmental Authority has imposed
material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars or any Alternate Currency in the London interbank market, then, on notice thereof by such Lender to Agent, any obligation of such Lender to
make or continue LIBOR Loans or to convert Base Rate Loans to LIBOR Loans shall be suspended until such Lender notifies Agent that the circumstances giving rise to such determination no longer exist. Upon delivery of such notice, Borrowers shall
prepay or, if applicable, convert all LIBOR Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such LIBOR Loans to such day, or immediately, if such
Lender may not lawfully continue to maintain such LIBOR Loans. Upon any such prepayment or conversion, Borrowers shall also pay accrued interest on the amount so prepaid or converted. 

3.6. Inability to Determine Rates. 

3.6.1. Subject to Section 3.6.2 through Section 3.6.5 below, Agent will promptly notify
Borrower Agent and Lenders if, in connection with any Loan or request with respect to a Loan, (a) Agent determines that (i) Dollar deposits are not being offered to banks in the London interbank Eurodollar market for the applicable Loan
amount or Interest Period, or (ii) adequate and reasonable means do not exist for determining LIBOR for the Loan or Interest Period (including with respect to calculation of the Base Rate) or (b) Agent or Required Lenders determine for any
reason that LIBOR for the Interest Period does not adequately and fairly reflect the cost to Lenders of funding or maintaining the Loan. Thereafter, Lenders’ obligations to make or maintain affected LIBOR Loans and utilization of the LIBOR
component (if affected) in determining Base Rate shall 

  
 -55- 

 
be suspended until Agent determines (or is instructed by Required Lenders) to withdraw the notice. Upon receipt of such notice, Borrower Agent may revoke any pending request for funding,
conversion or continuation of a LIBOR Loan or, failing that, will be deemed to have requested a Base Rate Loan, and Agent may (or shall upon request by Required Lenders) immediately convert any affected LIBOR Loan to a Base Rate Loan. 

3.6.2. Replacement of LIBOR. Notwithstanding anything to the contrary herein or in any other Loan Document, 

(a) on March 5, 2021 the Financial Conduct Authority (“FCA”), the regulatory supervisor of LIBOR’s administrator
(“IBA”), announced in a public statement the future cessation or loss of representativeness of overnight/Spot Next, 1-week, 1-month, 2-month, 3-month, 6-month and 12- month U.S. Dollar LIBOR tenor settings. On the earliest
of (i) the date that all Available Tenors of U.S. Dollar LIBOR have permanently or indefinitely ceased to be provided by IBA or have been announced by the FCA pursuant to public statement or publication of information to be no longer
representative, (ii) June 30, 2023, and (iii) the Early Opt-in Effective Date in respect of a SOFR Early Opt-in, if the then-current Benchmark is LIBOR,
the Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any setting of such Benchmark on such day and all subsequent settings without any amendment to, or further action or consent
of any other party to, this Agreement or any other Loan Document. If the Benchmark Replacement is Daily Simple SOFR, all interest will be payable on a monthly basis; 

(b) (i) upon (A) the occurrence of a Benchmark Transition Event or (B) a determination by Agent that neither of the alternatives
under clause (a) of the definition of Benchmark Replacement are available, the Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after
5:00 p.m. on the fifth Business Day after the date notice of such Benchmark Replacement is provided to Lenders, without any amendment to, or further action or consent of any other party to, any Loan Document as long as Agent has not received, by
such time, written notice of objection to such Benchmark Replacement from Lenders comprising Required Lenders (and any such objection shall be conclusive and binding absent manifest error); provided, that solely in the event that the then-current
Benchmark at the time of such Benchmark Transition Event is not a SOFR-based rate, the Benchmark Replacement therefor shall be determined in accordance with clause (a) of the definition of Benchmark Replacement unless Agent determines that
neither of such alternative rates is available; and (ii) on the Early Opt-in Effective Date in respect of an Other Rate Early Opt-in, the Benchmark Replacement will
replace LIBOR for all purposes under the Loan Documents in respect of any setting of such Benchmark on such day and all subsequent settings without any amendment to, or further action or consent of any other party to, any Loan Document; and 

(c) at any time that the administrator of the then-current Benchmark has permanently or indefinitely ceased to provide such Benchmark or such
Benchmark has been announced by the regulatory supervisor for the administrator of such Benchmark pursuant to public statement or publication of information to be no longer representative of the underlying market and economic reality that such
Benchmark is intended to measure and that representativeness will not be restored, Borrowers may revoke any request for a borrowing of, conversion to or continuation of Loans to be made, converted or continued that would bear interest by reference
to such Benchmark until Borrowers’ receipt of notice from Agent that a Benchmark Replacement has replaced such Benchmark, and, failing that, Borrowers will be deemed to have converted any such request into a request for a borrowing of or
conversion to Base Rate Loans. During the period referenced in the foregoing sentence, the component of Base Rate based on the Benchmark will not be used in any determination of Base Rate. 

  
 -56- 

 3.6.3. Conforming Changes. In connection with the implementation and administration
of a Benchmark Replacement, Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Benchmark
Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement. 
 3.6.4.
Notice. Agent will promptly notify Borrower Agent and Lenders of the implementation of any Benchmark Replacement and the effectiveness of any Benchmark Replacement Conforming Changes. Any determination, decision or election that may be made
by Agent pursuant to this Section, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date, and any decision to take or
refrain from taking any action, will be conclusive and binding absent manifest error and may be made in its discretion and without consent from any other party hereto, except, in each case, as expressly required pursuant to this Section. 

3.6.5. Term Tenors. At any time (including in connection with the implementation of a Benchmark Replacement), (a) if the then-current
Benchmark is a term rate (including Term SOFR or LIBOR), Agent may remove any tenor of such Benchmark that is unavailable or non-representative for Benchmark (including Benchmark Replacement) settings; and
(b) Agent may reinstate any such previously removed tenor for Benchmark (including Benchmark Replacement) settings. 
 3.7. Increased
Costs; Capital Adequacy. 
 3.7.1. Change in Law. If any Change in Law shall: 

(a) impose, modify or deem applicable any reserve, liquidity, special deposit, compulsory loan, insurance charge or similar requirement
against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in calculating LIBOR) or Issuing Bank; 

(b) subject any Lender or Issuing Bank to any Tax with respect to any Loan, Loan Document, Letter of Credit or participation in LC
Obligations, or change the basis of taxation of payments to such Lender or Issuing Bank in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 5.9 and the imposition of, or any change in the rate
of, any Excluded Tax payable by such Lender or Issuing Bank); or 
 (c) impose on any Lender, Issuing Bank or interbank market any other
condition, cost or expense affecting any Loan, Loan Document, Letter of Credit, participation in LC Obligations, or Commitment; 

  
 -57- 

 and the result thereof shall be to increase the cost to such Lender of making or maintaining any Loan or
Commitment, or to increase the cost to such Lender or Issuing Bank of participating in, issuing or maintaining any Letter of Credit, or to reduce the amount of any sum received or receivable by such Lender or Issuing Bank hereunder (whether of
principal, interest or any other amount) then, upon request of such Lender or Issuing Bank, Borrowers will pay to such Lender or Issuing Bank, as applicable, such additional amount or amounts as will compensate such Lender or Issuing Bank, as
applicable, for such additional costs incurred or reduction suffered. 
 3.7.2. Capital Adequacy. If any Lender or Issuing Bank
determines that any Change in Law affecting such Lender or Issuing Bank or any Lending Office of such Lender or such Lender’s or Issuing Bank’s holding company, if any, regarding capital or liquidity requirements has or would have the
effect of reducing the rate of return on such Lender’s, Issuing Bank’s or holding company’s capital as a consequence of this Agreement, or such Lender’s or Issuing Bank’s Commitments, Loans, Letters of Credit or
participations in LC Obligations, to a level below that which such Lender, Issuing Bank or holding company could have achieved but for such Change in Law (taking into consideration such Lender’s, Issuing Bank’s and holding company’s
policies with respect to capital adequacy and liquidity), then from time to time Borrowers will pay to such Lender or Issuing Bank, as the case may be, such additional amount or amounts as will compensate it or its holding company for any such
reduction suffered. 
 3.7.3. LIBOR Loan Reserves. If any Lender is required to maintain reserves with respect to liabilities or
assets consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”), Borrowers shall pay additional interest to such Lender on each LIBOR Loan equal to the costs of such reserves allocated to
the Loan by the Lender (as determined by it in good faith, which determination shall be conclusive). The additional interest shall be due and payable on each interest payment date for the Loan; provided, that if the Lender notifies Borrower
Agent (with a copy to Agent) of the additional interest less than 10 days prior to the interest payment date, then such interest shall be payable 10 days after Borrower Agent’s receipt of the notice. 

3.7.4. Compensation. Failure or delay on the part of any Lender or Issuing Bank to demand compensation pursuant to this Section shall
not constitute a waiver of its right to demand such compensation, but Borrowers shall not be required to compensate a Lender or Issuing Bank for any increased costs incurred or reductions suffered more than nine months prior to the date that the
Lender or Issuing Bank notifies Borrower Agent of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or Issuing Bank’s intention to claim compensation therefor (except that, if the Change in Law giving
rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof). 

3.8. Mitigation; Replacement of Lenders under Certain Circumstances. If any Lender gives a
notice under Section 3.5 or requests compensation under Section 3.7, or if Borrowers are required to pay additional amounts with respect to a Lender under Section 5.9,
then such Lender shall use reasonable efforts to designate a different Lending Office or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the judgment of such Lender, such designation or
assignment (a) would eliminate the need for such notice or reduce amounts payable or to be withheld in the future, as applicable; and (b) would not subject the Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to it or unlawful. Borrowers shall pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. Borrowers shall be permitted to replace any Lender that gives a notice under
Section 3.5 or 3.6 or requests compensation under Section 3.7, or if Borrowers are required to pay additional amounts with respect to a Lender under Section 5.9,

  
 -58- 

 
with a replacement lender; provided that (i) no Event of Default shall have occurred and be continuing at the time of such replacement, (ii) the replacement lender shall purchase, at
par, all Loans and other amounts owing to such replaced Lender on or prior to the date of replacement, (iii) the replacement lender, if not an Eligible Assignee, shall be satisfactory to the Agent, (iv) the replaced Lender shall be
obligated to make such replacement in accordance with the provisions of Section 13.3, (v) the Borrowers shall pay all additional amounts (if any) required pursuant to Section 3.5 or 3.7, as
the case may be, in respect of any period prior to the date on which such replacement shall be consummated, and (vi) any such replacement shall not be deemed to be a waiver of any rights that the Borrowers, the Agent or any other Lender shall
have against the replaced Lender. 
 3.9. Funding Losses. If for any reason (other than default by a Lender)
(a) any Borrowing of, or conversion to or continuation of, a LIBOR Loan does not occur on the date specified therefor in a Notice of Borrowing or Notice of Conversion/Continuation (whether or not withdrawn), (b) any repayment or conversion
of a LIBOR Loan occurs on a day other than the end of its Interest Period, (c) Borrowers fail to repay a LIBOR Loan when required hereunder, or (d) a Lender (other than a Defaulting Lender) is required to assign a LIBOR Loan prior to the
end of its Interest Period pursuant to Section 3.8 or 13.4, then Borrowers shall pay to Agent its customary administrative charge and to each Lender all resulting losses and expenses, including loss of anticipated
profits and any loss or expense arising from liquidation or redeployment of funds or from fees payable to terminate deposits of matching funds. Lenders shall not be required to purchase Dollar deposits in any interbank or offshore Dollar market to
fund any LIBOR Loan, but this Section shall apply as if each Lender had purchased such deposits. 
 3.10. Maximum
Interest. Regardless of any provision contained in any of the Loan Documents, in no contingency or event whatsoever shall the aggregate of all amounts that are contracted for, charged or received by Agent or any Lender pursuant to the
terms of this Agreement or any of the other Loan Documents and that are deemed interest under Applicable Law exceed the highest rate permissible under any Applicable Law (the “Maximum Rate”). No agreements, conditions, provisions or
stipulations contained in this Agreement or any of the other Loan Documents or the exercise by Agent of the right to accelerate the payment or the maturity of all or any portion of the Obligations, or the exercise of any option whatsoever contained
in any of the Loan Documents, or the prepayment by any Obligor of any of the Obligations, or the occurrence of any contingency whatsoever, shall entitle Agent or Lenders to charge or receive in any event, interest or any charges, amounts, premiums
or fees deemed interest by Applicable Law (such interest, charges, amounts, premiums and fees referred to herein collectively as “Interest”) in excess of the Maximum Rate and in no event shall any Obligor be obligated to pay
Interest exceeding such Maximum Rate, and all agreements, conditions or stipulations, if any, which may in any event or contingency whatsoever operate to bind, obligate or compel any Obligor to pay Interest exceeding the Maximum Rate shall be
without binding force or effect, at law or in equity, to the extent only of the excess of Interest over such Maximum Rate. If any Interest is charged or received with respect to the Obligations in excess of the Maximum Rate
(“Excess”), each Obligor stipulates that any such charge or receipt shall be the result of an accident and bona fide error, and such Excess, to the extent received, shall be applied first to reduce the principal Obligations and the
balance, if any, returned to the Obligors, it being the intent of the parties hereto not to enter into an usurious or otherwise illegal relationship. The right to accelerate the maturity of any of the Obligations does not include the right to
accelerate any Interest that has not otherwise accrued on the date of such acceleration, and neither Agent nor any Lender intends to collect any unearned Interest in the event of any such acceleration. Each Obligor recognizes that, with fluctuations
in 

  
 -59- 

 
the rates of interest set forth in this Agreement, and the Maximum Rate, such an unintentional result could inadvertently occur. All monies paid to Agent or any Lender hereunder or under any of
the other Loan Documents, whether at maturity or by prepayment, shall be subject to any rebate of unearned Interest as and to the extent required by Applicable Law. By the execution of this Agreement, each Obligor covenants that (i) the credit
or return of any Excess shall constitute the acceptance by each Obligor of such Excess, and (ii) each Obligor shall not seek or pursue any other remedy, legal or equitable, against Agent or any Lender, based in whole or in part upon contracting
for, charging or receiving any Interest in excess of the Maximum Rate. For the purpose of determining whether or not any Excess has been contracted for, charged or received by Agent or any Lender, all Interest at any time contracted for, charged or
received from any Obligor in connection with any of the Loan Documents shall, to the extent permitted by Applicable Law, be amortized, prorated, allocated and spread in equal parts throughout the full term of the Obligations. Obligors, Agent and
Lenders shall, to the maximum extent permitted under Applicable Law, (i) characterize any non-principal payment as an expense, fee or premium rather than as Interest and (ii) exclude voluntary
prepayments and the effects thereof. The provisions of this Section 3.10 shall be deemed to be incorporated into every Loan Document (whether or not any provision of this Section is referred to therein). All such Loan
Documents and communications relating to any Interest owed by any Obligor and all figures set forth therein shall, for the sole purpose of computing the extent of Obligations, be automatically recomputed by the Obligors, and by any court considering
the same, to give effect to the adjustments or credits required by this Section 3.10. 
 SECTION 4. LOAN ADMINISTRATION

 4.1. Manner of Borrowing and Funding Revolver Loans. 

4.1.1. Notice of Borrowing. 

(a) Whenever Borrowers desire funding of a Borrowing of Revolver Loans, Borrower Agent shall give Agent a Notice of Borrowing. Such notice
must be received by Agent no later than 2:00 p.m. (i) on the Business Day of the requested funding date, in the case of Base Rate Loans, and (ii) at least three Business Days prior to the requested funding date, in the case of LIBOR Loans.
Notices received after 2:00 p.m. shall be deemed received on the next Business Day. Each Notice of Borrowing shall be irrevocable and shall specify (A) the amount of the Borrowing, (B) the requested funding date (which must be a Business
Day), (C) whether the Borrowing is to be made as Base Rate Loans or LIBOR Loans, and (D) in the case of LIBOR Loans, the duration of the applicable Interest Period (which shall be deemed to be 30 days if not specified). 

(b) Unless payment is otherwise timely made by Borrowers, the becoming due of any Obligations (whether principal, interest, fees or other
charges, including Extraordinary Expenses, LC Obligations, Cash Collateral and Secured Bank Product Obligations) shall be deemed to be a request for Base Rate Revolver Loans on the due date, in the amount of such Obligations. The proceeds of such
Revolver Loans shall be disbursed as direct payment of the relevant Obligation. In addition, Agent may, at its option, charge such Obligations against any operating, investment or other account of a Borrower maintained with Agent or any of its
Affiliates. 

  
 -60- 

 (c) If Borrowers maintain any disbursement account with Agent or any Affiliate of Agent,
then presentation for payment of any Payment Item when there are insufficient funds to cover it shall be deemed to be a request for a Base Rate Revolver Loan on the date of such presentation, in the amount of the Payment Item. The proceeds of such
Revolver Loan may be disbursed directly to the disbursement account. 
 4.1.2. Fundings by Lenders. Each Lender shall timely honor its
Revolver Commitment by funding its Pro Rata share of each Borrowing of Revolver Loans that is properly requested hereunder. Except for Borrowings to be made as Swingline Loans, Agent shall endeavor to notify Lenders of each Notice of Borrowing (or
deemed request for a Borrowing) by 3:00 p.m. on the proposed funding date for Base Rate Loans or by 3:00 p.m. at least two Business Days before any proposed funding of LIBOR Loans. Each Lender shall fund to Agent such Lender’s Pro Rata share of
the Borrowing to the account specified by Agent in immediately available funds not later than 4:00 p.m. on the requested funding date, unless Agent’s notice is received after the times provided above, in which case Lender shall fund its Pro
Rata share by 11:00 a.m. on the next Business Day. Subject to its receipt of such amounts from Lenders, Agent shall disburse the proceeds of the Revolver Loans as directed by Borrower Agent. Unless Agent shall have received (in sufficient time to
act) written notice from a Lender that it does not intend to fund its Pro Rata share of a Borrowing, Agent may assume that such Lender has deposited or promptly will deposit its share with Agent, and Agent may disburse a corresponding amount to
Borrowers. If a Lender’s share of any Borrowing or of any settlement pursuant to Section 4.1.3(b) is not received by Agent, then Borrowers agree to repay to Agent on demand the amount of such share, together
with interest thereon from the date disbursed until repaid, at the rate applicable to the Borrowing. 
 4.1.3. Swingline Loans;
Settlement. 
 (a) Agent may, but shall not be obligated to, advance Swingline Loans to Borrowers, up to an aggregate outstanding amount
of $15,000,000, unless the funding is specifically required to be made by all Lenders hereunder. Each Swingline Loan shall constitute a Revolver Loan for all purposes, except that payments thereon shall be made to Agent for its own account. The
obligation of Borrowers to repay Swingline Loans shall be evidenced by the records of Agent and need not be evidenced by any promissory note. 

(b) Settlement of Swingline Loans and other Revolver Loans among Lenders and Agent shall take place on a date determined from time to time by
Agent (but at least weekly), in accordance with the Settlement Report delivered by Agent to Lenders. Between settlement dates, Agent may in its discretion apply payments on Revolver Loans to Swingline Loans, regardless of any designation by Borrower
or any provision herein to the contrary. Each Lender’s obligation to make settlements with Agent is absolute and unconditional, without offset, counterclaim or other defense, and whether or not the Commitments have terminated, an Overadvance
exists or the conditions in Section 6 are satisfied. If, due to an Insolvency Proceeding with respect to a Borrower or otherwise, any Swingline Loan may not be settled among Lenders hereunder, then each Lender shall be deemed to have purchased
from Agent a Pro Rata participation in such Loan and shall transfer the amount of such participation to Agent, in immediately available funds, within one Business Day after Agent’s request therefor. 

  
 -61- 

 4.1.4. Notices. Borrowers may request, convert or continue Loans, select interest
rates and transfer funds based on telephonic or e-mailed instructions to Agent. Borrowers shall confirm each such request by prompt delivery to Agent of a Notice of Borrowing or Notice of
Conversion/Continuation, if applicable, but if it differs materially from the action taken by Agent or Lenders, the records of Agent and Lenders shall govern. Neither Agent nor any Lender shall have any liability for any loss suffered by a Borrower
as a result of Agent or any Lender acting upon its understanding of telephonic or e-mailed instructions from a person believed in good faith by Agent or any Lender to be a person authorized to give such
instructions on a Borrower’s behalf. 
 4.2. Defaulting Lender. 

4.2.1. Reallocation of Pro Rata Share; Amendments. For purposes of determining Lenders’ obligations to fund or participate in Loans
or Letters of Credit, Agent may exclude the Commitments and Loans of any Defaulting Lender(s) from the calculation of Pro Rata shares; provided, however, that in no event will any Lender be required to fund or participate in Loans or Letters of
Credit if as a result of such funding or participation the aggregate amount of such Lender’s Revolver Loans and participations in LC Obligations would exceed its Commitment. A Defaulting Lender shall have no right to vote on any amendment,
waiver or other modification of a Loan Document, except as provided in Section 15.1.1(c). 
 4.2.2. Payments;
Fees. Agent may, in its discretion, receive and retain any amounts payable to a Defaulting Lender under the Loan Documents, and a Defaulting Lender shall be deemed to have assigned to Agent such amounts until all Obligations owing to Agent, non-Defaulting Lenders and other Secured Parties have been paid in full. Agent may apply such amounts to the Defaulting Lender’s defaulted obligations, use the funds to Cash Collateralize such Lender’s
Fronting Exposure, or readvance the amounts to Borrowers hereunder. A Lender shall not be entitled to receive any fees accruing hereunder during the period in which it is a Defaulting Lender, and the unfunded portion of its Commitment shall be
disregarded for purposes of calculating the unused line fee under Section 3.2.1. If any LC Obligations owing to a Defaulting Lender are reallocated to other Lenders, fees attributable to such LC Obligations under
Section 3.2.2 shall be paid to such Lenders. Agent shall be paid all fees attributable to LC Obligations that are not reallocated. 

4.2.3. Status; Cure. Agent may determine in its discretion that a Lender constitutes a Defaulting Lender and the effective date of such
status shall be conclusive and binding on all parties, absent manifest error. Borrowers, Agent and Issuing Bank may agree in writing that a Lender is no longer a Defaulting Lender. At such time, Pro Rata shares shall be reallocated without exclusion
of such Lender’s Commitments and Loans, and all outstanding Revolver Loans, LC Obligations and other exposures under the Revolver Commitments shall be reallocated among Lenders and settled by Agent (with appropriate payments by the reinstated
Lender) in accordance with the readjusted Pro Rata shares. Unless expressly agreed by Borrowers, Agent and Issuing Bank, no reinstatement of a Defaulting Lender shall constitute a waiver or release of claims against such Lender. The failure of any
Lender to fund a Loan, to make a payment in respect of LC Obligations or otherwise to perform its obligations hereunder shall not relieve any other Lender of its obligations, and no Lender shall be responsible for default by another Lender.

 4.3. Number and Amount of LIBOR Loans; Determination of Rate. Each Borrowing of LIBOR Loans when made shall be
in a minimum amount of $1,000,000, plus any increment of $500,000 in excess thereof. No more than ten (10) Borrowings of LIBOR Loans may be outstanding at any time, and all LIBOR Loans having the same length and beginning date of their Interest
Periods shall be aggregated together and considered one Borrowing for this purpose. Upon determining LIBOR for any Interest Period requested by Borrowers, Agent shall promptly notify Borrowers thereof by telephone or electronically and, if requested
by Borrowers, shall confirm any telephonic notice in writing. 

  
 -62- 

 4.4. Borrower Agent. Each Borrower hereby designates US
Concrete (“Borrower Agent”) as its representative and agent for all purposes under the Loan Documents, including requests for Loans and Letters of Credit, designation of interest rates, delivery or receipt of communications,
preparation and delivery of Borrowing Base and financial reports, receipt and payment of Obligations, requests for waivers, amendments or other accommodations, actions under the Loan Documents (including in respect of compliance with covenants), and
all other dealings with Agent, Issuing Bank or any Lender. Borrower Agent hereby accepts such appointment. Agent and Lenders shall be entitled to rely upon, and shall be fully protected in relying upon, any notice or communication (including any
notice of borrowing) delivered by Borrower Agent on behalf of any Borrower. Agent and Lenders may give any notice or communication with a Borrower hereunder to Borrower Agent on behalf of such Borrower. Each of Agent, Issuing Bank and Lenders shall
have the right, in its discretion, to deal exclusively with Borrower Agent for any or all purposes under the Loan Documents. Each Borrower agrees that any notice, election, communication, representation, agreement or undertaking made on its behalf
by Borrower Agent shall be binding upon and enforceable against it. 
 4.5. One Obligation. The Loans, LC
Obligations and other Obligations constitute one general obligation of Borrowers and are secured by Agent’s Lien on all Collateral; provided, however, that Agent and each Lender shall be deemed to be a creditor of, and the holder of a separate
claim against, each Borrower to the extent of any Obligations jointly or severally owed by such Borrower. 
 4.6. Effect of
Termination . On the effective date of the termination of all Commitments, the outstanding Obligations shall be immediately due and payable, and any Lender may terminate its and its Affiliates’ Bank Products (including, only with the
consent of Agent, any Cash Management Services). Until Full Payment of the outstanding Obligations, all undertakings of Borrowers contained in the Loan Documents shall continue, and Agent shall retain its Liens in the Collateral and all of its
rights and remedies under the Loan Documents. Agent shall not be required to terminate its Liens unless it receives Cash Collateral or a written agreement, in each case satisfactory to it, protecting Agent and Lenders from the dishonor or return of
any Payment Items previously applied to the Obligations. Sections 3.4, 3.7, 3.9, 5.5, 5.9, 5.10, 12, 14.2, this Section, and each indemnity or waiver given by an Obligor or Lender in any Loan Document, shall survive Full Payment of the
Obligations. 
 SECTION 5. PAYMENTS 

5.1. General Payment Provisions. All payments of Obligations shall be made in Dollars, without offset, counterclaim
or defense of any kind, free of (and without deduction for) any Taxes, and in immediately available funds, not later than 1:00 p.m. on the due date. Any payment after such time shall be deemed made on the next Business Day. Any payment of a LIBOR
Loan prior to the end of its Interest Period shall be accompanied by all amounts due under Section 3.9. Borrowers agree that Agent shall have the continuing, exclusive right to apply and reapply payments and proceeds of
Collateral against the outstanding Obligations, in such manner as Agent deems advisable, but whenever possible, any prepayment of Loans shall be applied first to Base Rate Loans and then to LIBOR Loans. It being understood and agreed that any LC
Obligations denominated in an Alternate Currency shall be made in Dollars in the Dollar Amount of the Alternate Currency. 

  
 -63- 

 5.2. Repayment of Revolver Loans. Revolver Loans shall be due
and payable in full on the Revolver Termination Date, unless payment is sooner required hereunder. Revolver Loans may be prepaid from time to time, without penalty or premium. Concurrently with (a) any Asset Disposition of ABL Priority
Collateral (including any Machinery) (i) that occurs during a Trigger Period or the immediate effect of which disposition will be the commencement of a Trigger Period or (ii) which disposition is not permitted by the provisions of this
Agreement or (b) any other Asset Disposition of (i) Trucks that have a fair market or book value (whichever is more) of at least $1,000,000 or (ii) Inventory that has a fair market or book value (whichever is more) of at least
$1,000,000, or (iii) Accounts that have a fair market or book value (whichever is more) of at least $250,000 or (iv) Machinery that has a fair market or book value (whichever is more) of at least $1,000,000, Borrowers shall
prepay Revolver Loans in an amount equal to the Net Proceeds of such Asset Disposition, provided that any such prepayment shall not waive any Default or Event of Default otherwise arising under this Agreement due to such Asset Disposition. Subject
to Section 2.1.5, notwithstanding anything herein to the contrary, if an Overadvance exists, Borrowers shall, on the sooner of Agent’s demand or the first Business Day after any Borrower has knowledge thereof, repay the outstanding
Revolver Loans in an amount sufficient to reduce the principal balance of Revolver Loans to the Borrowing Base. 
 5.3. Payment
of Other Obligations. Obligations other than Loans and LC Obligations, shall be paid by Borrowers as provided in the Loan Documents or, if no payment date is specified, within five (5) Business Days of demand. 

5.4. Marshaling; Payments Set Aside. None of Agent or Lenders shall be under any obligation to marshal any assets
in favor of any Obligor or against any Obligations. If any payment by or on behalf of Borrowers is made to Agent, Issuing Bank or any Lender, or Agent, Issuing Bank or any Lender exercises a right of setoff, and such payment or the proceeds of such
setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by Agent, Issuing Bank or such Lender in its discretion) to be repaid to a
trustee, receiver or any other Person, then to the extent of such recovery, the Obligation originally intended to be satisfied, and all Liens, rights and remedies relating thereto, shall be revived and continued in full force and effect as if such
payment had not been made or such setoff had not occurred. 
 5.5. Application and Allocation of Payments. 

5.5.1. Application. Payments made by Borrowers hereunder shall be applied (a) first, as specifically required hereby;
(b) second, to Obligations then due and owing; (c) third, to other Obligations specified by Borrowers; and (d) fourth, as determined by Agent in its Permitted Discretion. 

5.5.2. Post-Default Allocation. Notwithstanding anything in any Loan Document to the contrary, during an Event of Default under
Section 11.1(j), or during any other Event of Default at the discretion of Agent or Required Lenders, monies to be applied to the Obligations, whether arising from payments by Obligors, realization on Collateral (subject to
the Intercreditor Agreement), setoff or otherwise, shall be allocated as follows:  

  
 -64- 

 (a) first, to all fees, indemnification, costs and expenses, including Extraordinary
Expenses, owing to Agent; 
 (b) second, to all amounts owing to Agent on Swingline Loans; 

(c) third, to all amounts owing to Issuing Bank; 

(d) fourth, to all Obligations (other than Secured Bank Product Obligations) constituting fees, indemnification, costs or expenses
owing to Lenders; 
 (e) fifth, to all Obligations constituting interest (other than Secured Bank Product Obligations); 

(f) sixth, to Cash Collateralization of LC Obligations; 

(g) seventh, to all Loans, and to Secured Bank Product Obligations arising under Hedging Agreements (including Cash Collateralization
thereof) up to the amount of reserves existing therefor; 
 (h) eighth, to all other Secured Bank Product Obligations; and 

(i) last, to all remaining Obligations. 

Amounts shall be applied to payment of each category of Obligations only after Full Payment of amounts payable from time to time under all preceding
categories. If amounts are insufficient to satisfy a category, they shall be paid ratably among outstanding Obligations in the category. Monies and proceeds obtained from an Obligor shall not be applied to its Excluded Swap Obligations, but
appropriate adjustments shall be made with respect to amounts obtained from other Obligors to preserve the allocations in any applicable category. Amounts distributed with respect to any Secured Bank Product Obligation shall be calculated using the
methodology reported to Agent for such Obligation (but no greater than the maximum amount reported to Agent). Agent shall have no obligation to calculate the amount of any Secured Bank Product Obligation and may request a reasonably detailed
calculation thereof from the applicable Secured Bank Product Provider. If the provider fails to deliver the calculation within five days following request, Agent may assume the amount is zero. The allocations set forth in this Section are solely to
determine the rights and priorities among Secured Parties, and may be changed by agreement among them without the consent of any Obligor. This Section is not for the benefit of or enforceable by any Obligor, and each Borrower irrevocably waives the
right to direct the application of any payments or Collateral proceeds subject to this Section. 
 5.5.3. Erroneous Application. Agent
shall not be liable for any application of amounts made by it in good faith and, if any such application is subsequently determined to have been made in error, the sole recourse of any Lender or other Person to which such amount should have been
made shall be to recover the amount from the Person that actually received it (and, if such amount was received by any Lender, such Lender hereby agrees to return it). 

5.6. Dominion Account. The ledger balance in the main Dominion Account as of the end of a Business Day shall be
applied to the Obligations at the beginning of the next Business Day, during any FCCR Trigger Period. If, as a result of such application, a credit balance exists, the balance shall not accrue interest in favor of Borrowers and shall be made
available to Borrowers as long as no Default or Event of Default exists. 

  
 -65- 

 5.7. Account Stated. The Agent shall maintain in accordance with
its usual and customary practices account(s) evidencing the Debt of Borrowers hereunder. Any failure of Agent to record anything in a loan account, or any error in doing so, shall not limit or otherwise affect the obligation of Borrowers to pay any
amount owing hereunder. Entries made in a loan account shall constitute presumptive evidence of the information contained therein. If any information contained in a loan account is provided to or inspected by any Person, the information shall be
conclusive and binding on such Person for all purposes absent manifest error, except to the extent such Person notifies Agent in writing within 30 days after receipt or inspection that specific information is subject to dispute. 

5.8. Taxes. 
 5.8.1.
Payments Free of Taxes. All payments by Obligors of Obligations shall be free and clear of and without reduction for any Taxes. If Applicable Law requires any Obligor or Agent to withhold or deduct any Tax (including backup withholding or
withholding Tax), the withholding or deduction shall be based on information provided pursuant to Section 5.9 and Agent shall pay the amount withheld or deducted to the relevant Governmental Authority. If the withholding or
deduction is made on account of Indemnified Taxes or Other Taxes, the sum payable by Borrowers shall be increased so that Agent, Lender or Issuing Bank, as applicable, receives an amount equal to the sum it would have received if no such withholding
or deduction (including deductions applicable to additional sums payable under this Section) had been made. Without limiting the foregoing, Borrowers shall timely pay all Other Taxes to the relevant Governmental Authorities. 

5.8.2. Payment. Borrowers shall indemnify, hold harmless and reimburse (within 10 days after demand therefor) Agent, Lenders and Issuing
Bank for any Indemnified Taxes or Other Taxes (including those attributable to amounts payable under this Section but excluding any amounts directly attributable to such indemnitee’s gross negligence or willful misconduct) withheld or deducted
by any Obligor or Agent, or paid by Agent, any Lender or Issuing Bank, with respect to any Obligations, Letters of Credit or Loan Documents, whether or not such Taxes were properly asserted by the relevant Governmental Authority, and including all
penalties, interest and reasonable expenses relating thereto, as well as any amount that a Lender or Issuing Bank fails to pay indefeasibly to Agent under Section 5.9. A certificate as to the amount of any such payment or
liability delivered to Borrower Agent by Agent, or by a Lender or Issuing Bank (with a copy to Agent), shall be conclusive, absent manifest error. As soon as practicable after any payment of Taxes by a Borrower, Borrower Agent shall deliver to Agent
a receipt from the Governmental Authority or other evidence of payment satisfactory to Agent. 
 5.9. Lender Tax Information.

 5.9.1. Status of Lenders. Each Lender shall deliver documentation and information to Agent and Borrower Agent, at the times and
in form required by Applicable Law or reasonably requested by Agent or Borrower Agent, sufficient to permit Agent or Borrowers to determine (a) whether or not payments made with respect to Obligations are subject to Taxes, (b) if
applicable, the required rate of withholding or deduction, and (c) such Lender’s entitlement to any available exemption from, or reduction of, applicable Taxes for such payments or otherwise to establish such Lender’s status for
withholding tax purposes in the applicable jurisdiction. 

  
 -66- 

 5.9.2. Documentation. If a Borrower is resident for tax purposes in the United
States, any Lender that is a “United States person” within the meaning of section 7701(a)(30) of the Code shall deliver to Agent and Borrower Agent IRS Form W-9 or such other documentation or
information prescribed by Applicable Law or reasonably requested by Agent or Borrower Agent to determine whether such Lender is subject to backup withholding or information reporting requirements. If any Foreign Lender is entitled to any exemption
from or reduction of withholding tax for payments with respect to the Obligations, it shall deliver to Agent and Borrower Agent, on or prior to the date on which it becomes a Lender hereunder (and from time to time thereafter upon request by Agent
or Borrower Agent, but only if such Foreign Lender is legally entitled to do so), (a) IRS Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party;
(b) IRS Form W-8ECI; (c) IRS Form W-8IMY and all required supporting documentation; (d) in the case of a Foreign Lender claiming the benefits of the
exemption for portfolio interest under section 881(c) of the Code, IRS Form W-8BEN and a certificate showing such Foreign Lender is not (i) a “bank” within the meaning of section 881(c)(3)(A) of
the Code, (ii) a “10 percent shareholder” of any Obligor within the meaning of section 881(c)(3)(B) of the Code, or (iii) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code; or
(e) any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in withholding tax, together with such supplementary documentation necessary to allow Agent and Borrowers to determine the withholding or
deduction required to be made. 
 5.9.3. Lender Obligations. Each Lender and Issuing Bank shall promptly notify Borrowers and Agent of
any change in circumstances that would change any claimed Tax exemption or reduction. Each Lender and Issuing Bank shall indemnify, hold harmless and reimburse (within 10 days after demand therefor) Borrowers and Agent for any Taxes, losses, claims,
liabilities, penalties, interest and expenses (including reasonable attorneys’ fees) incurred by or asserted against a Borrower or Agent by any Governmental Authority due to such Lender’s or Issuing Bank’s failure to deliver, or
inaccuracy or deficiency in, any documentation required to be delivered by it pursuant to this Section. Each Lender and Issuing Bank authorizes Agent to set off any amounts due to Agent under this Section against any amounts payable to such Lender
or Issuing Bank under any Loan Document. 
 5.10. Nature and Extent of Each Borrower’s Liability. 

5.10.1. Joint and Several Liability. Each Borrower agrees that it is jointly and severally liable for, and absolutely and
unconditionally guarantees to Agent and Lenders the prompt payment and performance of, all Obligations and all agreements under the Loan Documents, except its Excluded Swap Obligations. Each Borrower agrees that its guaranty obligations hereunder
constitute a continuing guaranty of payment and not of collection, that such obligations shall not be discharged until Full Payment of the Obligations, and that such obligations are absolute and unconditional, irrespective of (a) the
genuineness, validity, regularity, enforceability, subordination or any future modification of, or change in, any Obligations or Loan Document, or any other document, instrument or agreement to which any Obligor is or may become a party or be bound;
(b) the absence of any action to enforce this Agreement (including this Section) or any other Loan Document, or any waiver, consent or indulgence of any kind by Agent or any Lender with respect thereto; (c) the existence, value or
condition of, or failure to perfect a Lien or to preserve rights against, any security or guaranty for the Obligations or any action, or the absence of any action, by 

  
 -67- 

 
Agent or any Lender in respect thereof (including the release of any security or guaranty); (d) the insolvency of any Obligor; (e) any election by Agent or any Lender in an Insolvency
Proceeding for the application of Section 1111(b)(2) of the Bankruptcy Code; (f) any borrowing or grant of a Lien by any other Borrower, as
debtor-in-possession under Section 364 of the Bankruptcy Code or otherwise; (g) the disallowance of any claims of Agent or any Lender against any Obligor for
the repayment of any Obligations under Section 502 of the Bankruptcy Code or otherwise; or (h) any other action or circumstances that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, except
Full Payment of all Obligations. 
 5.10.2. Waivers. 

(a) Each Borrower expressly waives all rights that it may have now or in the future under any statute, at common law, in equity or otherwise,
to compel Agent or Lenders to marshal assets or to proceed against any Obligor, other Person or security for the payment or performance of any Obligations before, or as a condition to, proceeding against such Borrower. Each Borrower waives all
defenses available to a surety, guarantor or accommodation co-Obligor other than Full Payment of all Obligations and waives, to the maximum extent permitted by law, any right to revoke any guaranty of any
Obligations as long as it is a Borrower. It is agreed among each Borrower, Agent and Lenders that the provisions of this Section 5.10 are of the essence of the transaction contemplated by the Loan Documents and that, but
for such provisions, Agent and Lenders would decline to make Loans and issue Letters of Credit. Each Borrower acknowledges that its guaranty pursuant to this Section is necessary to the conduct and promotion of its business, and can be expected to
benefit such business. 
 (b) Agent may, in its discretion, pursue such rights and remedies as it deems appropriate, including realization
upon Collateral by judicial foreclosure or nonjudicial sale or enforcement, without affecting any rights and remedies under this Section 5.10. If, in taking any action in connection with the exercise of any rights or
remedies, Agent or any Lender shall forfeit any other rights or remedies, including the right to enter a deficiency judgment against any Borrower or other Person, whether because of any Applicable Laws pertaining to “election of remedies”
or otherwise, each Borrower consents to such action and waives any claim based upon it, even if the action may result in loss of any rights of subrogation that any Borrower might otherwise have had. Any election of remedies that results in denial or
impairment of the right of Agent or any Lender to seek a deficiency judgment against any Borrower shall not impair any other Borrower’s obligation to pay the full amount of the Obligations. Each Borrower waives all rights and defenses arising
out of an election of remedies, such as nonjudicial foreclosure with respect to any security for the Obligations, even though that election of remedies destroys such Borrower’s rights of subrogation against any other Person. Agent or any Lender
may bid all or a portion of the Obligations at any foreclosure, trustee or other sale, including any private sale, and the amount of such bid need not be paid by Agent but shall be credited against the Obligations. The amount of the successful bid
at any such sale, whether Agent or any other Person is the successful bidder, shall be conclusively deemed to be the fair market value of the Collateral, and the difference between such bid amount and the remaining balance of the Obligations shall
be conclusively deemed to be the amount of the Obligations guaranteed under this Section 5.10, notwithstanding that any present or future law or court decision may have the effect of reducing the amount of any deficiency
claim to which Agent or any Lender might otherwise be entitled but for such bidding at any such sale. 

  
 -68- 

 5.10.3. Extent of Liability; Contribution. 

(a) Notwithstanding anything herein to the contrary, each Borrower’s liability under this Section 5.10 shall be
limited to the greater of (i) all amounts for which such Borrower is primarily liable, as described below, and (ii) such Borrower’s Allocable Amount. 

(b) If any Borrower makes a payment under this Section 5.10 of any Obligations (other than amounts for which such
Borrower is primarily liable) (a “Guarantor Payment”) that, taking into account all other Guarantor Payments previously or concurrently made by any other Borrower, exceeds the amount that such Borrower would otherwise have paid if
each Borrower had paid the aggregate Obligations satisfied by such Guarantor Payments in the same proportion that such Borrower’s Allocable Amount bore to the total Allocable Amounts of all Borrowers, then such Borrower shall be entitled to
receive contribution and indemnification payments from, and to be reimbursed by, each other Borrower for the amount of such excess, pro rata based upon their respective Allocable Amounts in effect immediately prior to such Guarantor Payment. The
“Allocable Amount” for any Borrower shall be the maximum amount that could then be recovered from such Borrower under this Section 5.10 without rendering such payment voidable under Section 548 of the
Bankruptcy Code or under any applicable state fraudulent transfer or conveyance act, or similar statute or common law. 
 (c) Nothing
contained in this Section 5.10 shall limit the liability of any Borrower to pay Loans made directly or indirectly to that Borrower (including Loans advanced to any other Borrower and then
re-loaned or otherwise transferred to, or for the benefit of, such Borrower), LC Obligations relating to Letters of Credit issued to support such Borrower’s business, and all accrued interest, fees,
expenses and other related Obligations with respect thereto, for which such Borrower shall be primarily liable for all purposes hereunder. Agent and Lenders shall have the right, at any time in their discretion, to condition Loans and Letters of
Credit upon a separate calculation of borrowing availability for each Borrower and to restrict the disbursement and use of such Loans and Letters of Credit to such Borrower. 

(d) Each Obligor that is a Qualified ECP when its guaranty of or grant of Lien as security for a Swap Obligation becomes effective hereby
jointly and severally, absolutely, unconditionally and irrevocably undertakes to provide funds or other support to each Specified Obligor with respect to such Swap Obligation as may be needed by such Specified Obligor from time to time to honor all
of its obligations under the Loan Documents in respect of such Swap Obligation (but, in each case, only up to the maximum amount of such liability that can be hereby incurred without rendering such Qualified ECP’s obligations and undertakings
under this Section 5.10 voidable under any applicable fraudulent transfer or conveyance act). The obligations and undertakings of each Qualified ECP under this Section shall remain in full force and effect until Full
Payment of all Obligations. Each Obligor intends this Section to constitute, and this Section shall be deemed to constitute, a guarantee of the obligations of, and a “keepwell, support or other agreement” for the benefit of, each Obligor
for all purposes of the Commodity Exchange Act. 
 5.10.4. Joint Enterprise. Each Borrower has requested that Agent and Lenders make
this credit facility available to Borrowers on a combined basis, in order to finance Borrowers’ business most efficiently and economically. Borrowers’ business is a mutual and collective enterprise, and the successful operation of each
Borrower is dependent upon the successful performance of the integrated group. Borrowers believe that consolidation of their credit facility will enhance the borrowing power of each Borrower and ease administration of the facility, all to their
mutual advantage. Borrowers acknowledge that Agent’s and Lenders’ willingness to extend credit and to administer the Collateral on a combined basis hereunder is done solely as an accommodation to Borrowers and at Borrowers’ request.

  
 -69- 

 5.10.5. Subordination. Each Borrower hereby subordinates any claims, including any
rights at law or in equity to payment, subrogation, reimbursement, exoneration, contribution, indemnification or set off, that it may have at any time against any other Obligor, howsoever arising, to the Full Payment of all Obligations. 

SECTION 6. CONDITIONS PRECEDENT 
 6.1.
Conditions Precedent to Initial Loans. In addition to the conditions set forth in Section 6.2, this Agreement and the Lenders obligations to fund any requested Loan, issue any Letter of Credit, or
otherwise extend credit to Borrowers hereunder shall become effective on the date on which (such date, the “Closing Date”) each of the following conditions has been satisfied:

Liens upon the Collateral, except Permitted Liens. 
 (c) Agent shall have received certificates, in form and substance satisfactory to it,

delivery of the Loan Documents is true and complete, and that such resolutions are in full force and effect, were duly adopted, have not been amended, modified or revoked, and constitute all resolutions adopted with respect to this credit facility;
and (iii) to the title, name and signature of each Person authorized to sign the Loan Documents. Agent may conclusively rely on this certificate until it is otherwise notified by the applicable Obligor in writing.

(i) Borrowers shall have paid all fees and expenses to be paid to Agent and Lenders on the Closing Date. 

(j) The Agent and the Lenders shall have received, at least three (3) Business Days prior to the Closing Date, all documentation and
other information that they reasonably determine is required by regulatory authorities under “know your customer” and anti-money laundering rules and regulations, including the PATRIOT ACT and Beneficial Ownership Regulation, to the extent
reasonably requested at least ten (10) Business Days prior to the Closing Date. If any Borrower qualifies as a “legal entity customer” under the Beneficial Ownership Regulation, it shall have provided a Beneficial Ownership
Certification to Agent and Lenders in relation to such Borrower.

page to this Agreement shall be deemed to have consented to, approved or accepted, or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable to a Lender or Agent unless Agent shall

 Notwithstanding the foregoing or any other provision of this Agreement or any other Loan

The security interests and Liens granted in the Collateral are given in renewal, confirmation, extension and modification, but not in extinguishment, of the
security interests and Liens previously granted in the Collateral pursuant to the Loan and Security Agreement, dated as of August 31, 2012, among US Concrete, the other Borrower party thereto, the Guarantors party thereto, the Lenders party
thereto and Agent, the First Amended and Restated Loan and Security Agreement, dated as of October 29, 2013, the Second Amended and Restated Loan and Security Agreement, dated as of November 18, 2015 and the Initial Loan Agreement; such
prior security interests and Liens are not extinguished hereby; and the making, perfection and priority of such prior security interests and Liens shall continue in full force and effect. 

7.2. Liens on Deposit Accounts, Securities Accounts and Commodity Accounts; Cash Collateral. 

7.2.1. Deposit Accounts, Securities Accounts and Commodity Accounts. To further secure the prompt payment and performance of all
Obligations, each Obligor hereby grants to Agent a continuing security interest in and Lien upon all amounts credited to any Deposit Account (including any sums in any blocked or lockbox accounts or in any accounts into which such sums are swept)
and all amounts credited to, and all financial assets and other funds or Property held in, any Securities Account and/or Commodities Account of such Obligor. Each Obligor hereby authorizes and directs each bank or other depository, securities
intermediary or commodities intermediary, as applicable, to deliver to Agent, upon request, all balances in any Deposit Account maintained by such Obligor (other than Excluded Deposit Accounts) and all Investment Property, funds, commodity contracts
and other Property credited to or held in any Securities Account or Commodity Accounts, as applicable (other than Excluded Securities and Commodities Accounts), without inquiry into the authority or right of Agent to make such request. 

7.2.2. Cash Collateral. Cash Collateral may be invested, at Agent’s discretion (and with the consent of Obligors, as long as no
Event of Default exists), but Agent shall have no duty to do so, regardless of any agreement or course of dealing with any Obligor, and shall have no responsibility for any investment or loss. Each Obligor hereby grants to Agent, as security for the
Obligations, a security interest in all Cash Collateral held from time to time and all proceeds thereof, whether held in a Cash Collateral Account or otherwise. Agent may apply Cash Collateral to the payment of Obligations as they become due, in
such order as Agent may elect. Each Cash Collateral Account and all Cash Collateral shall be under the sole dominion and control of Agent, and no Obligor or other Person shall have any right to any Cash Collateral, until Full Payment of all
Obligations.

7.4. Other Collateral. 

7.4.1. Commercial Tort Claims. Borrowers shall promptly notify Agent in writing if any Obligor has a Commercial Tort Claim (other than,
as long as no Default or Event of Default exists, a Commercial Tort Claim for less than $500,000), shall promptly amend Schedule 9.1.16 to include such claim, and shall take such actions as Agent reasonably deems appropriate to subject such
claim to a duly perfected, first priority (or second priority, to the extent such Property is “priority collateral” (or similar term) for the Term Loan B Facility or Permitted Secured Debt under the Intercreditor Agreement) Lien in favor
of Agent. 
 7.4.2. Certain After-Acquired Collateral. Borrowers shall promptly notify Agent in writing if, after the Closing Date,
any Obligor obtains any interest in any Collateral consisting of Commodity Accounts, Deposit Accounts, Securities Accounts, Chattel Paper, Documents, Instruments, Intellectual Property, Investment Property or Letter-of-Credit Rights, in each case with a nominal value in excess of $200,000 and, upon Agent’s request, shall promptly take such actions as Agent deems appropriate to effect Agent’s duly
perfected, first priority (or second priority, to the extent such Property is “priority collateral” (or similar term) for the Term Loan B Facility or Permitted Secured Debt under the Intercreditor Agreement) Lien upon such Collateral,
including obtaining any appropriate possession, control agreement or Lien Waiver. If any Collateral is in the possession of a third party, at Agent’s request, Borrowers shall obtain an acknowledgment that such third party holds the Collateral
for the benefit of Agent. 
 7.5. No Assumption of Liability. The Lien on Collateral granted hereunder is given
as security only and shall not subject Agent or any Lender to, or in any way modify, any obligation or liability of Obligors relating to any Collateral. In no event shall the grant of any Lien under any Loan Document secure an Excluded Swap
Obligation of the granting Obligor. 
 7.6. Further Assurances. All Liens granted to Agent under the Loan
Documents are for the benefit of Secured Parties. Promptly upon request, Borrowers shall deliver such instruments and agreements, and shall take such actions, as Agent deems appropriate under Applicable Law to evidence or perfect its Lien on any
Collateral, or otherwise to give effect to the intent of this Agreement. Each Obligor authorizes Agent to file any financing statement that describes the Collateral as “all assets” or “all personal property” of such Obligor, or
words to similar effect, and ratifies any action taken by Agent before the Closing Date to effect or perfect its Lien on any Collateral. 

  
 -74- 

 7.7. Additional Borrowers. Borrower Agent may designate any
Subsidiary as a Borrower under this Agreement and the other Loan Documents upon satisfaction of each of the following conditions, provided that such Subsidiary owns Eligible Accounts, Eligible Inventory, Eligible Trucks or Eligible Machinery: 

(a) Borrower Agent shall have delivered to the Agent a written notice requesting that such Subsidiary be designated as a new
Borrower. 
 (b) The Agent shall have received a duly executed supplement to this Agreement and any other applicable Loan
Documents joining such Subsidiary as a Borrower hereunder (such supplement to be in form and substance reasonably satisfactory to the Agent) and such other documents or agreements as Agent may request in its Permitted Discretion. 

(c) Such Subsidiary shall deliver to the Agent such documents and certificates referred to in
Section 6.1(d) as may be reasonably requested by the Agent (it being agreed by US Concrete that, if the designation of such Subsidiary as a Borrower obligates the Agent or any Lender to comply with “know your
customer” or similar identification procedures or the Beneficial Ownership Regulation in circumstances where the necessary information is not already available to it, US Concrete shall, promptly upon the request of the Agent or any Lender,
supply such documentation and other evidence as is reasonably requested by the Agent or any Lender in order for the Agent or such Lender to carry out, and be satisfied it has complied with the results of, all necessary “know your
customer”, Beneficial Ownership Regulation or other similar checks under all Applicable Law). 
 (d) If not previously
granted to the Agent under this Agreement, as so supplemented, and the Security Documents, such Subsidiary shall grant a security interest in all Collateral owned by such Subsidiary by delivering to the Agent a duly executed supplement to each
applicable Security Document or such other documents as the Agent shall reasonably deem appropriate for such purpose. 
 SECTION 8. COLLATERAL
ADMINISTRATION 
 8.1. Borrowing Base Certificates. By the 20th day of each month (or on the succeeding
Business Day, if the applicable day is not a Business Day), Borrowers shall deliver to Agent (and Agent shall promptly deliver same to Lenders) a Borrowing Base Certificate prepared as of the close of business of the previous month, and during any
Trigger Period Borrowers shall also deliver to Agent (and Agent shall promptly deliver same to Lenders) a Borrowing Base Certificate on a weekly basis, and in no event later than the 5th day of each week, prepared as of the close of the last day of
the preceding week; provided, however, that during any period when an Event of Default exists, Borrowers shall deliver a Borrowing Base Certificate as frequently as shall be requested by Agent. All calculations of Availability in any
Borrowing Base Certificate shall originally be made by Borrowers and certified by a Senior Officer, provided that Agent may from time to time review and, in its Permitted Discretion, after Required Reserve Notice (provided that in no event shall
such a Required Reserve Notice be required prior to or in connection with denying a request for a Revolver Loan due to insufficient Availability resulting from an adjustment in the calculation of Availability as contemplated by this Section), adjust
any such calculation (a) to reflect its reasonable estimate of declines in value of any Collateral, due to collections received in the Dominion Account or otherwise; (b) to adjust advance rates to reflect changes in

  
 -75- 

 
dilution, quality, mix and other factors affecting Collateral; and (c) to the extent the calculation is not made in accordance with this Agreement or does not accurately reflect the
Availability Reserve, but in each case without duplication of (i) factors taken into consideration in determining eligibility of the relevant Accounts, Inventory, Trucks and Machinery and (ii) factors taken into consideration in
determining the Availability Reserve. 
 8.2. Administration of Accounts. 

8.2.1. Records and Schedules of Accounts. Each Borrower shall keep accurate and complete records of its Accounts, including all payments
and collections thereon, and shall submit to Agent sales, collection, reconciliation and other reports in form satisfactory to Agent in its Permitted Discretion, on such periodic basis as Agent may request in its Permitted Discretion. Each Borrower
shall also provide to Agent, on or before the 20th day of each month, a detailed aged trial balance of all Accounts as of the end of the preceding month, specifying each Account’s Account
Debtor name and amount, invoice date and due date, showing any and such other information as Agent may request from time to time in its Permitted Discretion. If Accounts in an aggregate face amount of $1,000,000 or more cease to be Eligible
Accounts, Borrowers shall notify Agent of such occurrence promptly (and in any event within one Business Day) after any Borrower has knowledge thereof. 

8.2.2. Taxes. If an Account of any Borrower includes a charge for any Taxes, Agent is authorized, in its Permitted Discretion and after
Required Reserve Notice to the Borrower, to pay the amount thereof to the proper taxing authority for the account of such Borrower and to charge Borrowers therefor; provided, however, that neither Agent nor Lenders shall be liable for
any Taxes that may be due from Borrowers or with respect to any Collateral. 
 8.2.3. Account Verification. Whether or not a Default
or Event of Default exists, Agent shall have the right at any time, in the name of Agent, any designee of Agent or any Borrower, to verify the validity, amount or any other matter relating to any Accounts of Borrowers by mail, telephone or
otherwise. Prior to conducting any such verification, Agent shall provide reasonable prior notice (as determined by Agent in its Permitted Discretion) thereof to Borrower Agent, unless a Default exists or Agent determines that not providing such
notice is appropriate to protect the interests of the Lenders. Borrowers shall cooperate fully with Agent in an effort to facilitate and promptly conclude any such verification process. 

8.2.4. Maintenance of Dominion Account. Borrowers shall maintain Dominion Accounts pursuant to lockbox or other arrangements acceptable
to Agent in its Permitted Discretion. Borrowers shall obtain an agreement (in form and substance satisfactory to Agent in its Permitted Discretion) from each lockbox servicer and Dominion Account bank, establishing Agent’s control over and Lien
in the lockbox or Dominion Account, which may be exercised by Agent during any FCCR Trigger Period, requiring immediate deposit of all remittances received in the lockbox to a Dominion Account, and waiving offset rights of such servicer or bank,
except for customary administrative charges. If a Dominion Account is not maintained with Bank of America, Agent may, during any FCCR Trigger Period, require immediate transfer of all funds in such account to a Dominion Account maintained with Bank
of America. Agent and Lenders assume no responsibility to Borrowers for any lockbox arrangement or Dominion Account, including any claim of accord and satisfaction or release with respect to any Payment Items accepted by any bank. 

  
 -76- 

 8.2.5. Proceeds of Collateral. Borrowers shall request in writing and otherwise take
all necessary steps to ensure that all payments on Accounts or otherwise relating to Collateral are made directly to a Dominion Account (or a lockbox relating to a Dominion Account). If any Borrower or Subsidiary receives cash or Payment Items with
respect to any Collateral, it shall hold same in trust for Agent and promptly (not later than the next Business Day) deposit same into a Dominion Account. 

8.3. Administration of Inventory. 

8.3.1. Records and Reports of Inventory. Each Borrower shall keep accurate and complete records of its Inventory, including costs and
daily withdrawals and additions, and shall submit to Agent inventory and reconciliation reports in form satisfactory to Agent, on such periodic basis as Agent may request in its Permitted Discretion. Each Borrower shall conduct a physical inventory
at least once per calendar year (and on a more frequent basis if requested by Agent when an Event of Default exists) and periodic cycle counts consistent with historical practices, and, upon the request of Agent in its Permitted Discretion, shall
provide to Agent a report based on each such inventory and count promptly upon completion thereof, together with such supporting information as Agent may request in its Permitted Discretion. Agent may participate in and observe each physical count
at its own expense (unless an Event of Default exists, then at the Borrowers’ sole expense). 
 8.3.2. Returns of Inventory. No
Borrower shall return any Inventory to a supplier, vendor or other Person, whether for cash, credit or otherwise, unless (a) such return is in the Ordinary Course of Business; (b) no Default, Event of Default or Overadvance exists or would
result therefrom; (c) Agent is promptly notified if the aggregate Value of all Inventory returned in any month exceeds $1,000,000; and (d) any payment received by a Borrower for a return is promptly remitted to Agent for application to the
Obligations.

Other than Inventory for chemical admixtures utilized to manufacture ready-mix concrete (“Permitted Consignment Inventory”), no Borrower shall acquire or accept any Inventory on consignment or approval, and shall take all steps to assure that all Inventory is
produced in accordance with Applicable Law, including the FLSA. All Permitted Consignment Inventory shall be kept in separate containers, segregated from all other Inventory of the Obligors. Permitted Consignment Inventory shall in no event
constitute Eligible Inventory. No Borrower shall sell any Inventory on consignment or approval or any other basis under which the customer may return or require a Borrower to repurchase such Inventory. Borrowers shall use, store and maintain all
Inventory with reasonable care and caution, in accordance with applicable standards of any insurance and in conformity with all Applicable Law in all material respects, and shall make current rent payments (within applicable grace periods provided
for in leases) at all locations where any Collateral is located.

to Eligible Trucks and all other Trucks and otherwise in form and substance satisfactory to Agent in its Permitted Discretion, indicating, if applicable, (A) changes in value and Depreciation Amounts and (B) which Trucks were purchased or
otherwise acquired during such period and (ii) a summary report of the Machinery, differentiating with respect to Eligible Machinery and all other Machinery and otherwise in form and substance satisfactory to Agent in its Permitted Discretion,

Governmental Authority (in lieu of a physical certificate of title), a copy of the notification with respect to such notation received from such Governmental Authority), and provide and/or file all other documents or instruments (including any
necessary powers of attorney) necessary to have the Lien of the Agent noted on any such certificate of title or with the appropriate state office.

 8.4.3. Condition of Equipment. The Equipment is in good operating condition and
repair, and all necessary replacements and repairs have been made so that the value and operating efficiency of the Equipment is preserved at all times, reasonable wear and tear excepted. Each Borrower shall use commercially reasonable efforts to
ensure that the Equipment is mechanically and structurally sound, and capable of performing the functions for which it was designed, in accordance with manufacturer specifications. No Borrower shall permit any Equipment to become affixed to real
Property unless any landlord or mortgagee delivers a Lien Waiver.

Borrowers at the business locations set forth in Schedule 8.6.1, except that Borrowers may (a) make sales or other dispositions of Collateral in accordance with Section 10.2.5; (b) move Collateral to
another location in the United States, Canada or Puerto Rico listed on Schedule 8.6.1; and (c) upon 15 Business Days’ prior written notice to Agent, move Collateral to another location in the United States, Canada and Puerto Rico.
Each Borrower may from time to time, with the consent of Agent, in its Permitted Discretion, amend Schedule 8.6.1 to add additional locations in the United States, Canada and Puerto Rico. 

8.6.2. Insurance of Collateral; Condemnation Proceeds. 

(a) Each Borrower shall maintain insurance with respect to the Collateral, covering casualty, hazard, theft, malicious mischief, flood and
other risks, in amounts, with endorsements and with insurers (with a Best’s Financial Strength Rating of at least A_ VII, unless otherwise approved by Agent) reasonably satisfactory to Agent.
All proceeds, subject however, to the provisions of the Intercreditor Agreement, under each policy shall be payable to Agent. Agent hereby agrees that self-insurance policies in effect on the Closing Date meet the foregoing insurance requirements as
to the type of insurance covered by such self-insurance. From time to time upon request, Borrowers shall deliver to Agent the originals or certified copies of its insurance policies and updated flood plain searches. Unless Agent shall agree
otherwise, each policy shall include satisfactory endorsements (i) showing Agent as lender loss payee; (ii) requiring 30 days prior written notice to Agent in the event of cancellation of the policy for any reason whatsoever; and
(iii) specifying that the interest of Agent shall not be impaired or invalidated by any act or neglect of any Borrower or the owner of the Property, nor by the occupation of the premises for purposes more hazardous than are permitted by the
policy. If any Borrower fails to provide and pay for any insurance, Agent may, at its option, but shall not be required to, procure the insurance and charge Borrowers therefor. Each Borrower agrees to deliver to Agent, promptly as rendered, copies
of all reports made to insurance companies. While no Event of Default exists, Borrowers may settle, adjust or compromise any insurance claim, as long as the proceeds are delivered to Agent. If an Event of Default exists, only Agent shall be
authorized to settle, adjust and compromise such claims. 
 (b) During a Trigger Period and subject to the Intercreditor Agreement (if in
effect at such time), any proceeds of insurance arising from ABL Priority Collateral (other than proceeds from workers’ compensation or D&O insurance) and any awards arising from condemnation of ABL Priority Collateral shall be applied to
payment of the Revolver Loans, and then to any other Obligations outstanding. When a Trigger Period is not in effect, any insurance proceeds or condemnation awards relating to any loss or destruction of (i) Trucks that have a fair market or
book value (whichever is more) of at least $1,000,000, (ii) Inventory that has a fair market or book value (whichever is more) of at least $1,000,000 or (iii) Machinery that has a fair market or book value (whichever is more) of at least
$1,000,000 shall be applied to payment of the Revolver Loans, and then to any other Obligations outstanding. If the Term Loan B Facility or any Permitted Secured Debt is outstanding at such time, proceeds of and awards in respect of any
“priority collateral” (or similar term) of the Term Loan B Facility or such Permitted Secured Debt under the Intercreditor Agreement shall be applied as provided in the definitive documents governing the Term Loan B Facility or such
Permitted Secured Debt and in compliance with the Intercreditor Agreement. 
  

  
 -80- 

 (c) If requested by Borrowers in writing within 30 days after Agent’s receipt of any
insurance proceeds or condemnation awards relating to any loss or destruction of Equipment or Real Estate (in each case, to the extent the Term Loan B Facility or any Permitted Secured Debt is outstanding at such time, other than “priority
collateral” (or similar term) of the Term Loan B Facility or such Permitted Secured Debt under and subject to the Intercreditor Agreement), Borrowers may use such proceeds or awards to repair or replace such Equipment or Real Estate (and until
so used, the proceeds shall be held by Agent as Cash Collateral) as long as (i) no Default or Event of Default exists; (ii) such repair or replacement is promptly undertaken and concluded, in accordance with plans satisfactory to Agent;
(iii) replacement buildings are constructed on the sites of the original casualties and are of comparable size, quality and utility to the destroyed buildings; (iv) the repaired or replaced Property is free of Liens, other than Permitted
Liens that are not Purchase Money Liens; (v) Borrowers comply with disbursement procedures for such repair or replacement as Agent may reasonably require; and (vi) the aggregate amount of such proceeds or awards from any single casualty or
condemnation does not exceed $2,500,000. 
 8.6.3. Protection of Collateral. All expenses of protecting, storing, warehousing,
insuring, handling, maintaining and shipping any Collateral, all Taxes payable with respect to any Collateral (including any sale thereof), and all other payments required to be made by Agent to any Person to realize upon any Collateral, shall be
borne and paid by Borrowers. Agent shall not be liable or responsible in any way for the safekeeping of any Collateral, for any loss or damage thereto (except for reasonable care in its custody while Collateral is in Agent’s actual possession),
for any diminution in the value thereof, or for any act or default of any warehouseman, carrier, forwarding agency or other Person whatsoever, but the same shall be at Borrowers’ sole risk. 

8.6.4. Defense of Title. Each Borrower shall use commercially reasonable efforts to defend its title (and if applicable, the title of
the relevant Guarantors) to Collateral and Agent’s Liens therein against all Persons, claims and demands, except Permitted Liens. 

8.7. Power of Attorney. Each Obligor hereby irrevocably constitutes and appoints Agent (and all Persons designated
by Agent) as such Obligor’s true and lawful attorney (and agent-in-fact) for the purposes provided in this Section. Agent, or Agent’s designee, may, without
notice and in either its or an Obligor’s name, but at the cost and expense of Borrowers: 
 (a) Endorse an Obligor’s name on any
Payment Item or other proceeds of Collateral (including proceeds of insurance) that come into Agent’s possession or control; and 
 (b)
During an Event of Default, (i) notify any Account Debtors of the assignment of their Accounts, demand and enforce payment of Accounts by legal proceedings or otherwise, and generally exercise any rights and remedies with respect to Accounts;

 SECTION 9. REPRESENTATIONS AND WARRANTIES 

9.1. General Representations and Warranties. To induce Agent and Lenders to enter into this Agreement and to make
available the Commitments, Loans and Letters of Credit, each Obligor represents and warrants that: 
 9.1.1. Organization and
Qualification. Each Obligor and Subsidiary is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, except to the extent otherwise described on Schedule 9.1.1 attached hereto. Each
Obligor and Subsidiary is duly qualified, authorized to do business and in good standing as a foreign corporation in each jurisdiction where failure to be so qualified could reasonably be expected to have a Material Adverse Effect, except to the
extent otherwise described on Schedule 9.1.1 attached hereto. The information included in the Beneficial Ownership Certification(s) most recently provided to Agent and each Lender is true and complete in all respects. 

9.1.2. Power and Authority. Each Obligor is duly authorized to execute, deliver and perform its Loan Documents. The execution, delivery
and performance of the Loan Documents have been duly authorized by all necessary action, and do not (a) require any consent or approval of any holders of Equity Interests of any Obligor, except those already obtained; (b) contravene the
Organic Documents of any Obligor; (c) violate or cause a default under any Applicable Law or Material Contract; or (d) result in or require the imposition of any Lien (other than Permitted Liens) on any Obligor’s Property. 

9.1.3. Enforceability. Each Loan Document is a legal, valid and binding obligation of each Obligor party thereto, enforceable in
accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally. 

9.1.4. Capital Structure. Schedule 9.1.4 shows, as of the Closing Date, for each Obligor and Subsidiary, its name, jurisdiction
of organization, authorized and issued Equity Interests, holders of its Equity Interests, and agreements binding on such holders with respect to such Equity Interests. Except as disclosed on Schedule 9.1.4, since August 31, 2017 and as
of the Closing Date, no Obligor or Subsidiary has acquired any substantial assets from any other Person nor been the surviving entity in a merger or combination. Each Obligor has good title to its Equity Interests in its Subsidiaries, subject only
to Permitted Liens, and all such Equity Interests are duly issued, and, to the extent in the form of corporate stock, fully paid and non-assessable. Except as described on Schedule 9.1.4, as of the
Closing Date, there are no outstanding purchase options, warrants, subscription rights, agreements to issue or sell, convertible interests, phantom rights or powers of attorney relating to Equity Interests of any Obligor or Subsidiary. 

9.1.5. Title to Properties; Priority of Liens. Each Obligor and Subsidiary has good and indefeasible title to (or valid leasehold
interests in) all of its Real Estate necessary in the Ordinary Course of Business, and good title to all of its personal Property, including all Property reflected in any financial statements delivered to Agent or Lenders, in each case free of Liens
except Permitted Liens. Each Obligor and Subsidiary has paid and discharged all lawful claims that, if unpaid, could become a Lien on its Properties, other than Permitted Liens. All Liens of Agent in the Collateral are duly perfected, first priority
Liens, subject only to Permitted Liens that are expressly allowed to have priority over Agent’s Liens. 

  
 -82- 

 9.1.6. Accounts. Agent may rely, in determining which Accounts are Eligible Accounts,
on all statements and representations made by Borrowers with respect thereto. Borrowers warrant, with respect to each Account at the time it is shown as an Eligible Account in a Borrowing Base Certificate, that: 

(a) it is genuine and in all respects what it purports to be, and is not evidenced by a judgment; 

(b) it arises out of a completed, bona fide sale and delivery of goods or rendition of services in the Ordinary Course of Business, and
substantially in accordance with any purchase order, contract or other document relating thereto; 
 (c) it is for a sum certain, maturing
as stated in the invoice covering such sale or rendition of services, a copy of which has been furnished or is available to Agent on request; 

(d) to Borrowers’ knowledge, it is not subject to any offset, Lien (other than Agent’s Lien and, to the extent the Term Loan B
Facility or any Permitted Secured Debt is outstanding, the Liens securing the Term Loan B Facility or such Permitted Secured Debt), deduction, defense, dispute, counterclaim or other adverse condition except as arising in the Ordinary Course of
Business and disclosed to Agent; and it is absolutely owing by the Account Debtor, without contingency in any respect; 
 (e) no purchase
order, agreement, document or Applicable Law restricts assignment of the Account to Agent (regardless of whether, under the UCC, the restriction is ineffective), and the applicable Borrower is the sole payee or remittance party shown on the invoice;

 (f) no extension, compromise, settlement, modification, credit, deduction or return has been authorized with respect to the Account,
except discounts or allowances granted in the Ordinary Course of Business for prompt payment that are reflected on the face of the invoice related thereto and in the reports submitted to Agent hereunder; and 

(g) to the best of Borrowers’ knowledge, (i) there are no facts or circumstances that are reasonably likely to impair the
enforceability or collectibility of such Account; (ii) the Account Debtor had the capacity to contract when the Account arose, continues to meet the applicable Borrower’s customary credit standards, is Solvent, is not contemplating or
subject to an Insolvency Proceeding, and has not failed, or suspended or ceased doing business; and (iii) there are no proceedings or actions threatened or pending against any Account Debtor that could reasonably be expected to have a material
adverse effect on the Account Debtor’s financial condition.

of income, cash flow and shareholder’s equity, of US Concrete and Subsidiaries that have been and are hereafter delivered to Agent and Lenders, are prepared in accordance with GAAP, and fairly present in all material respects the financial
positions and results of operations of US Concrete and Subsidiaries at the dates and for the periods indicated, subject, in the case of quarterly and monthly statements, to normal year-end adjustments and
the absence of footnotes. All projections delivered from time to time to Agent and Lenders have been prepared in good faith, based on reasonable assumptions in light of the circumstances at such time. Since December 31, 2020 there has been no

Commitments shall terminate, without any action by Agent or notice of any kind. In addition, or if any other Event of Default exists, Agent may in its discretion (and shall upon written direction of Required Lenders) do any one or more of the
following from time to time: 

  
 -102- 

 (a) declare any Obligations (other than Secured Bank Product Obligations) immediately due
and payable, whereupon they shall be due and payable without diligence, presentment, demand, protest or notice of any kind, all of which are hereby waived by Borrowers to the fullest extent permitted by law; 

(b) terminate, reduce or condition any Commitment, or make any adjustment to the Borrowing Base; provided, Agent may not require Issuing

(d) exercise any other rights or remedies afforded under any agreement, by law, at equity or otherwise, including the rights and remedies of a

(iv) sell or otherwise dispose of any Collateral in its then condition, or after any further manufacturing or processing thereof, at public or private sale, with such notice as may be required by Applicable Law, in lots or in bulk, at such
locations, all as Agent, in its discretion, deems advisable. Each Obligor agrees that 10 days’ notice of any proposed sale or other disposition of Collateral by Agent shall be reasonable, and that any sale conducted on the internet or to a
licensor of Intellectual Property shall be commercially reasonable. Agent may conduct sales on any Obligor’s premises, without charge, and any sale may be adjourned from time to time in accordance with Applicable Law. Agent shall have the right
to sell, lease or otherwise dispose of any Collateral for cash, credit or any combination thereof, and Agent may purchase any Collateral at public or, if permitted by law, private sale and, in lieu of actual payment of the purchase price, may credit
bid and set off the amount of such price against the Obligations. 
 11.3. License. Agent is hereby granted an
irrevocable, non-exclusive license or other right, exercisable at any time an Event of Default exists, to use, license or sub-license (without payment of royalty or
other compensation to any Person) any or all Intellectual Property of Obligors, computer hardware and software, trade secrets, brochures, customer lists, promotional and advertising materials, labels, packaging materials and other Property, in

any of their Affiliates are authorized, to the fullest extent permitted by Applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency, but excluding deposits held by
Obligors in a fiduciary capacity) at any time held and 

  
 -103- 

 
other obligations (in whatever currency) at any time owing by Agent, Issuing Bank, such Lender or such Affiliate to or for the credit or the account of an Obligor against any Obligations,
irrespective of whether or not Agent, Issuing Bank, such Lender or such Affiliate shall have made any demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured or are owed to a branch or
office of Agent, Issuing Bank, such Lender or such Affiliate different from the branch or office holding such deposit or obligated on such indebtedness. The rights of Agent, Issuing Bank, each Lender and each such Affiliate under this Section are in
addition to other rights and remedies (including other rights of setoff) that such Person may have. 
 11.5. Remedies Cumulative; No
Waiver. 
 11.5.1. Cumulative Rights. All agreements, warranties, guaranties, indemnities and other undertakings of Obligors
under the Loan Documents are cumulative and not in derogation of each other. The rights and remedies of Agent and Lenders are cumulative, may be exercised at any time and from time to time, concurrently or in any order, and are not exclusive of any
other rights or remedies available by agreement, by law, at equity or otherwise. All such rights and remedies shall continue in full force and effect until Full Payment of all Obligations. 

11.5.2. Waivers. No waiver or course of dealing shall be established by (a) the failure or delay of Agent or any Lender to require
strict performance by Obligors with any terms of the Loan Documents, or to exercise any rights or remedies with respect to Collateral or otherwise; (b) the making of any Loan or issuance of any Letter of Credit during a Default, Event of
Default or other failure to satisfy any conditions precedent; or (c) acceptance by Agent or any Lender of any payment or performance by an Obligor under any Loan Documents in a manner other than that specified therein. It is expressly
acknowledged by Obligors that any failure to satisfy a financial covenant on a measurement date shall not be cured or remedied by satisfaction of such covenant on a subsequent date. 

SECTION 12. AGENT 
 12.1.
Appointment, Authority and Duties of Agent. 
 12.1.1. Appointment and Authority. Each Secured Party appoints and
designates Bank of America as Agent under all Loan Documents. Agent may, and each Secured Party authorizes Agent to, enter into all Loan Documents to which Agent is intended to be a party and accept all Security Documents, for the benefit of Secured
Parties. Any action taken by Agent in accordance with the provisions of the Loan Documents, and the exercise by Agent of any rights or remedies set forth therein, together with all other powers reasonably incidental thereto, shall be authorized by
and binding upon all Secured Parties. Without limiting the generality of the foregoing, Agent shall have the sole and exclusive authority to (a) act as the disbursing and collecting agent for Lenders with respect to all payments and collections
arising in connection with the Loan Documents; (b) execute and deliver as Agent each Loan Document, including any intercreditor or subordination agreement, and accept delivery of each Loan Document; (c) act as collateral agent for Secured
Parties for purposes of perfecting and administering Liens under the Loan Documents, and for all other purposes stated therein; (d) manage, supervise or otherwise deal with Collateral; and (e) take any Enforcement Action or otherwise
exercise any rights or remedies with respect to any Collateral or under any Loan Documents, Applicable Law or otherwise. The duties of Agent are ministerial and administrative in nature only, and Agent shall not have a

  
 -104- 

 
fiduciary relationship with any Secured Party, Participant or other Person, by reason of any Loan Document or any transaction relating thereto. Agent alone shall be authorized to determine
whether any Account or Inventory constitutes an Eligible Account or Eligible Inventory, whether any Trucks or Machinery constitutes Eligible Trucks or Eligible Machinery, whether to impose or release any reserve, or whether any conditions to funding
or to issuance of a Letter of Credit have been satisfied, which determinations and judgments, if exercised in good faith, shall exonerate Agent from liability to any Secured Party or other Person for any error in judgment. 

12.1.2. Duties. Agent shall not have any duties except those expressly set forth in the Loan Documents. The conferral upon Agent of any
right shall not imply a duty to exercise such right, unless instructed to do so by Lenders in accordance with this Agreement. 
 12.1.3.
Agent Professionals. Agent may perform its duties through agents and employees. Agent may consult with and employ Agent Professionals, and shall be entitled to act upon, and shall be fully protected in any action taken in good faith reliance
upon, any advice given by an Agent Professional. Agent shall not be responsible for the negligence or misconduct of any agents, employees or Agent Professionals selected by it with reasonable care. 

12.1.4. Instructions of Required Lenders. The rights and remedies conferred upon Agent under the Loan Documents may be exercised without
the necessity of joinder of any other party, unless required by Applicable Law. Agent may request instructions from Required Lenders or other Secured Parties with respect to any act (including the failure to act) in connection with any Loan
Documents or Collateral, and may seek assurances to its satisfaction from Secured Parties of their indemnification obligations against Claims that could be incurred by Agent. Agent may refrain from any act until it has received such instructions or
assurances, and shall not incur liability to any Person by reason of so refraining. Instructions of Required Lenders shall be binding upon all Secured Parties, and no Secured Party shall have any right of action whatsoever against Agent as a result
of Agent acting or refraining from acting pursuant to instructions of Required Lenders. Notwithstanding the foregoing, instructions by and consent of specific parties shall be required to the extent provided in
Section 15.1.1. In no event shall Agent be required to take any action that, in its opinion, is contrary to Applicable Law or any Loan Documents or could subject any Agent Indemnitee to personal liability. 

12.2. Agreements Regarding Collateral and Borrower Materials. 

12.2.1. Lien Releases; Care of Collateral. Secured Parties authorize Agent to release any Lien with respect to any Collateral
(a) upon Full Payment of the outstanding Obligations and termination of all Commitments; (b) that is the subject of a disposition or Lien that Borrowers certify in writing is a Permitted Asset Disposition or a Permitted Lien entitled to
priority over Agent’s Liens (and Agent may rely conclusively on any such certificate without further inquiry); (c) that does not constitute a material part of the Collateral; or (d) subject to Section 15.1,
with the consent of Required Lenders. Secured Parties authorize Agent to subordinate its Liens to any Purchase Money Lien or other Lien entitled to priority hereunder. Agent shall have no obligation to assure that any Collateral exists or is owned
by an Obligor, or is cared for, protected or insured, nor to assure that Agent’s Liens have been properly created, perfected or enforced, or are entitled to any particular priority, nor to exercise any duty of care with respect to any
Collateral. 

  
 -105- 

 12.2.2. Possession of Collateral. Agent and Secured Parties appoint each Lender as
agent (for the benefit of Secured Parties) for the purpose of perfecting Liens in any Collateral held or controlled by such Lender, to the extent such Liens are perfected by possession or control. If any Lender obtains possession or control of any
Collateral, it shall notify Agent thereof and, promptly upon Agent’s request, deliver such Collateral to Agent or otherwise deal with it in accordance with Agent’s instructions. 

12.2.3. Reports. Agent shall promptly provide to Lenders, when complete, any field audit, examination or appraisal report prepared for
Agent with respect to any Obligor or Collateral (“Report”). Reports and other Borrower Materials may be made available to Lenders by providing access to them on the Platform, but Agent shall not be responsible for system failures or
access issues that may occur from time to time. Each Lender agrees (a) that Reports are not intended to be comprehensive audits or examinations, and that Agent or any other Person performing an audit or examination will inspect only specific
information regarding the Obligations or Collateral and will rely significantly upon Borrowers’ books, records and representations; (b) that Agent makes no representation or warranty as to the accuracy or completeness of any Borrower
Materials and shall not be liable for any information contained in or omitted from any Borrower Materials, including any Report; and (c) to keep all Borrower Materials confidential and strictly for such Lender’s internal use, not to
distribute any Report or other Borrower Materials (or the contents thereof) to any Person (except to such Lender’s Participants, attorneys and accountants), and to use all Borrower Materials solely for administration of the Obligations. Each
Lender shall indemnify and hold harmless Agent and any other Person preparing a Report from any action such Lender may take as a result of or any conclusion it may draw from any Borrower Materials, as well as from any Claims arising as a direct or
indirect result of Agent furnishing same to such Lender, via the Platform or otherwise. 
 12.3. Reliance By
Agent. Agent shall be entitled to rely, and shall be fully protected in relying, upon any certification, notice or other communication (including those by telephone, telex, telegram, telecopy or
e-mail) believed by it to be genuine and correct and to have been signed, sent or made by the proper Person. Agent shall have a reasonable and practicable amount of time to act upon any instruction, notice or
other communication under any Loan Document, and shall not be liable for any delay in acting. 
 12.4. Action Upon
Default. Agent shall not be deemed to have knowledge of any Default or Event of Default, or of any failure to satisfy any conditions in Section 6, unless it has received written notice from a Borrower or
Required Lenders specifying the occurrence and nature thereof. If any Lender acquires knowledge of a Default, Event of Default or failure of such conditions, it shall promptly notify Agent and the other Lenders thereof in writing. Each Secured Party
agrees that, except as otherwise provided in any Loan Documents or with the written consent of Agent and Required Lenders, it will not take any Enforcement Action, accelerate Obligations (other than Secured Bank Product Obligations), or exercise any
right that it might otherwise have under Applicable Law to credit bid at foreclosure sales, UCC sales or other dispositions of Collateral, or to assert any rights relating to any Collateral. 

12.5. Ratable Sharing. If any Lender obtains any payment or reduction of any Obligation, whether through set-off or otherwise, in excess of its share of such Obligation, determined on a Pro Rata basis or in accordance with Section 5.5.2, as applicable, such Lender shall forthwith purchase from
Agent, Issuing Bank and the other Lenders such participations in the affected Obligation as are necessary to share the excess payment or reduction on a Pro Rata basis or in accordance with Section 5.5.2, as applicable. If
any of such payment or reduction is thereafter recovered from the purchasing Lender, the purchase shall be rescinded and the purchase 

  
 -106- 

 
price restored to the extent of such recovery, but without interest. Notwithstanding the foregoing, if a Defaulting Lender obtains a payment or reduction of any Obligation, it shall immediately
turn over the amount thereof to Agent for application under Section 4.2.2 and it shall provide a written statement to Agent describing the Obligation affected by such payment or reduction. No Lender shall set off against
any Dominion Account without Agent’s prior consent. 
 12.6. Indemnification. EACH LENDER SHALL INDEMNIFY
AND HOLD HARMLESS AGENT INDEMNITEES AND ISSUING BANK INDEMNITEES, TO THE EXTENT NOT REIMBURSED BY OBLIGORS, ON A PRO RATA BASIS, AGAINST ALL CLAIMS THAT MAY BE INCURRED BY OR ASSERTED AGAINST ANY SUCH INDEMNITEE, PROVIDED THAT ANY CLAIM AGAINST AN
AGENT INDEMNITEE RELATES TO OR ARISES FROM ITS ACTING AS OR FOR AGENT (IN THE CAPACITY OF AGENT). In no event shall any Lender have any obligation hereunder to indemnify or hold harmless an Agent Indemnitee with respect to a Claim that is determined
in a final, non-appealable judgment by a court of competent jurisdiction to result from the gross negligence or willful misconduct of such Agent Indemnitee. In Agent’s Permitted Discretion, it may reserve
for any Claims made against an Agent Indemnitee or Issuing Bank Indemnitee, and may satisfy any judgment, order or settlement relating thereto, from proceeds of Collateral prior to making any distribution of Collateral proceeds to Secured Parties.
If Agent is sued by any receiver, trustee or other Person for any alleged preference or fraudulent transfer, then any monies paid by Agent in settlement or satisfaction of such proceeding, together with all interest, costs and expenses (including
attorneys’ fees) incurred in the defense of same, shall be promptly reimbursed to Agent by each Lender to the extent of its Pro Rata share. 

12.7. Limitation on Responsibilities of Agent. Agent shall not be liable to any Secured Party for any action taken
or omitted to be taken under the Loan Documents, except for losses directly and solely caused by Agent’s gross negligence or willful misconduct. Agent does not assume any responsibility for any failure or delay in performance or any breach by
any Obligor, Lender or other Secured Party of any obligations under the Loan Documents. Agent does not make any express or implied representation, warranty or guarantee to Secured Parties with respect to any Obligations, Collateral, Loan Documents
or Obligor. No Agent Indemnitee shall be responsible to Secured Parties for any recitals, statements, information, representations or warranties contained in any Loan Documents or Borrower Materials; the execution, validity, genuineness,
effectiveness or enforceability of any Loan Documents; the genuineness, enforceability, collectibility, value, sufficiency, location or existence of any Collateral, or the validity, extent, perfection or priority of any Lien therein; the validity,
enforceability or collectibility of any Obligations; or the assets, liabilities, financial condition, results of operations, business, creditworthiness or legal status of any Obligor or Account Debtor. No Agent Indemnitee shall have any obligation
to any Secured Party to ascertain or inquire into the existence of any Default or Event of Default, the observance by any Obligor of any terms of the Loan Documents, or the satisfaction of any conditions precedent contained in any Loan Documents.

 12.8. Successor Agent and Co-Agents. 

12.8.1. Resignation; Successor Agent. Agent may resign at any time by giving at least 30 days written notice thereof to Lenders and
Borrowers. Upon receipt of such notice, Required Lenders shall have the right to appoint a successor Agent which shall be (a) a Lender or an Affiliate of a Lender; or (b) a financial institution reasonably acceptable to Required Lenders
and (provided no Default or Event of Default exists) Borrowers. If no successor agent is appointed 

  
 -107- 

 
by the effective date of Agent’s resignation, then on such date Agent may appoint a successor agent that is a financial institution acceptable to it, which shall be a Lender unless no Lender
accepts the role, or, in the absence of such appointment, Required Lenders shall automatically assume all rights and duties of Agent. Upon acceptance by a successor Agent of its appointment hereunder, such successor Agent shall thereupon succeed to
and become vested with all the powers and duties of the retiring Agent without further act. The retiring Agent shall be discharged from its duties hereunder on the effective date of its resignation, but shall continue to have all rights and
protections available to Agent under the Loan Documents with respect to actions, omissions, circumstances or Claims relating to or arising while it was acting or transferring responsibilities as Agent or holding any Collateral on behalf of Secured
Parties, including indemnification under Sections 12.6 and 15.2 and all rights and protections under this Section 12. Any successor to Bank of America by merger or acquisition of stock or this loan shall
continue to be Agent hereunder without further act on the part of any Secured Party or Obligor. 
 12.8.2.
Co-Collateral Agent. If necessary or appropriate under Applicable Law, Agent may appoint a Person to serve as a co-collateral agent or separate collateral agent
under any Loan Document. Each right and remedy intended to be available to Agent under the Loan Document shall also be vested in such agent. Secured Parties shall execute and deliver any instrument or agreement that Agent may request to effect such
appointment. If the agent shall die, dissolve, become incapable of acting, resign or be removed, then all the rights and remedies of such agent, to the extent permitted by Applicable Law, shall vest in and be exercised by Agent until appointment of
a new agent. 
 12.9. Due Diligence and Non-Reliance. Each Lender
acknowledges and agrees that it has, independently and without reliance upon Agent or any other Lenders, and based upon such documents, information and analyses as it has deemed appropriate, made its own credit analysis of each Obligor and its own
decision to enter into this Agreement and to fund Loans and participate in LC Obligations hereunder. Each Secured Party has made such inquiries as it feels necessary concerning the Loan Documents, Collateral and Obligors. Each Secured Party
acknowledges and agrees that the other Secured Parties have made no representations or warranties concerning any Obligor, any Collateral or the legality, validity, sufficiency or enforceability of any Loan Documents or Obligations. Each Secured
Party will, independently and without reliance upon any other Secured Party, and based upon such financial statements, documents and information as it deems appropriate at the time, continue to make and rely upon its own credit decisions in making
Loans and participating in LC Obligations, and in taking or refraining from any action under any Loan Documents. Except for notices, reports and other information expressly requested by a Lender, Agent shall have no duty or responsibility to provide
any Secured Party with any notices, reports or certificates furnished to Agent by any Obligor or any credit or other information concerning the affairs, financial condition, business or Properties of any Obligor (or any of its Affiliates) which may
come into possession of Agent or its Affiliates. 
 12.10. Remittance of Payments and Collections. 

12.10.1. Remittances Generally. All payments by any Lender to Agent shall be made by the time and on the day set forth in this
Agreement, in immediately available funds. If no time for payment is specified or if payment is due on demand by Agent and request for payment is made by Agent by 11:00 a.m. on a Business Day, payment shall be made by Lender not later than 2:00 p.m.
on such day, and if request is made after 11:00 a.m., then payment shall be made by 11:00 a.m. on the next Business Day. Payment by Agent to any Secured Party shall be made by wire transfer, in the type of funds received by Agent. Any such payment
shall be subject to Agent’s right of offset for any amounts due from such payee under the Loan Documents. 

  
 -108- 

 12.10.2. Failure to Pay. If any Secured Party fails to pay any amount when due by it
to Agent pursuant to the terms hereof, such amount shall bear interest, from the due date until paid in full, at the rate determined by Agent as customary for interbank compensation for two Business Days and thereafter at the Default Rate for Base
Rate Revolver Loans. In no event shall Borrowers be entitled to receive credit for any interest paid by a Secured Party to Agent, nor shall any Defaulting Lender be entitled to interest on any amounts held by Agent pursuant to
Section 4.2. 
 12.10.3. Recovery of Payments; Presumption by Agent. 

(a) If Agent determines that an amount received by it must be returned or paid to an Obligor or other Person pursuant to Applicable Law or
otherwise, then, notwithstanding any other term of any Loan Document, Agent shall not be required to distribute such amount to any Secured Party. If any amounts received and applied by Agent to any Obligations are later required to be returned by
Agent pursuant to Applicable Law, each Lender shall pay to Agent, on demand, such Lender’s Pro Rata share of the amounts required to be returned. 

(b) Unless Agent shall have received notice from Borrower Agent prior to the date on which any payment is due to Agent for the account of the
Lenders or the Issuing Bank hereunder that the Borrowers will not make such payment, Agent may assume that the Borrowers have made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders
or the Issuing Bank, as the case may be, the amount due. 
 (c) With respect to any payment that Agent makes for the account of the Lenders
or the Issuing Bank hereunder as to which Agent determines (which determination shall be conclusive absent manifest error) that any of the following applies (such payment referred to as the “Rescindable Amount”): (1) the Borrowers
have not in fact made such payment; (2) Agent has made a payment in excess of the amount so paid by Borrowers (whether or not then owed); or (3) Agent has for any reason otherwise erroneously made such payment; then each of the Lenders or
the Issuing Bank, as the case may be, severally agrees to repay to Agent forthwith on demand the Rescindable Amount so distributed to such Lender or the Issuing Bank, in immediately available funds with interest thereon, for each day from and
including the date such amount is distributed to it to but excluding the date of payment to Agent, at the greater of the Federal Funds Rate and a rate determined by Agent in accordance with banking industry rules on interbank compensation. A notice
of Agent to any Lender or the Borrower with respect to any amount owing under this Section 12.10.3 shall be conclusive, absent manifest error. 

(d) Without limitation of any other provision in this Agreement, if at any time Agent makes a payment hereunder in error to any Lender or the
Issuing Bank (the “Credit Party”), whether or not in respect of an Obligation due and owing by Borrowers at such time, where such payment is a Rescindable Amount, then in any such event, each Credit Party receiving a Rescindable
Amount severally agrees to repay to Agent forthwith on demand the Rescindable Amount received by such Credit Party in immediately available funds in the currency so received, with interest thereon, for each day from and including the date such
Rescindable Amount is 

  
 -109- 

 
received by it to but excluding the date of payment to Agent, at the greater of the Federal Funds Rate and a rate determined by Agent in accordance with banking industry rules on interbank
compensation. Each Credit Party irrevocably waives any and all defenses, including any “discharge for value” (under which a creditor might otherwise claim a right to retain funds mistakenly paid by a third party in respect of a debt owed
by another) or similar defense to its obligation to return any Rescindable Amount. Agent shall inform each Credit Party promptly upon determining that any payment made to such Credit Party comprised, in whole or in part, a Rescindable Amount. 

12.11. Individual Capacities. As a Lender, Bank of America shall have the same rights and remedies under the Loan
Documents as any other Lender, and the terms “Lenders,” “Required Lenders” or any similar term shall include Bank of America in its capacity as a Lender. Agent, Lenders and their Affiliates may accept deposits from, lend money
to, provide Bank Products to, act as financial or other advisor to, and generally engage in any kind of business with, Obligors and their Affiliates, as if they were not Agent or Lenders hereunder, without any duty to account therefor to any Secured
Party. In their individual capacities, Agent, Lenders and their Affiliates may receive information regarding Obligors, their Affiliates and their Account Debtors (including information subject to confidentiality obligations), and shall have no
obligation to provide such information to any Secured Party. 
 12.12. Titles. Each Lender, other than Bank of
America, that is designated (on the cover page of this Agreement or otherwise) by Bank of America as an “Arranger,” “Bookrunner” or “Agent” of any type shall have no right, power or duty under any Loan Documents other
than those applicable to all Lenders, and shall in no event have any fiduciary duty to any Secured Party. 
 12.13. Bank Product
Providers. Each Secured Bank Product Provider, by delivery of a notice to Agent of a Bank Product, agrees to be bound by the Loan Documents, including Section 5.5, this Section 12,
Section 15.3.3 and Section 15.23. Each Secured Bank Product Provider shall indemnify and hold harmless Agent Indemnitees, to the extent not reimbursed by Obligors, against all Claims that may be
incurred by or asserted against any Agent Indemnitee in connection with such provider’s Secured Bank Product Obligations. 
 12.14.
Certain ERISA Matters. 
 12.14.1. Lender Representations. Each Lender represents and warrants, as of the date it became a
Lender party hereto, and covenants, from the date it became a Lender party hereto to the date it ceases being a Lender party hereto, for the benefit of, Agent and not, for the avoidance of doubt, to or for the benefit of the Obligors, that at least
one of the following is and will be true: (a) Lender is not using “plan assets” (within the meaning of ERISA Section 3(42) or otherwise) of one or more Benefit Plans with respect to Lender’s entrance into, participation in,

collective investment funds) or PTE 96-23 (a class exemption for certain transactions determined by in-house asset managers), is applicable with respect to Lender’s
entrance into, participation in, administration of and performance of the Loans, Letters of Credit, Commitments and Loan

(b) through (g) of Part I of PTE 84-14, and (iv) to the best knowledge of Lender, the requirements of subsection (a) of Part I of PTE 84-14 are satisfied
with respect to Lender’s entrance into, participation in, administration of and performance of the Loans, Letters of Credit, Commitments and Loan Documents; or (d) such other representation, warranty and covenant as may be agreed in
writing between Agent, in its discretion, and Lender. 
 12.14.2. Further Lender Representation. Unless
Section 12.14.1(a) or (d) is true with respect to a Lender, such Lender further represents and warrants, as of the date it became a Lender hereunder, and covenants, from the date it became a Lender to the date
it ceases to be a Lender hereunder, for the benefit of, Agent and not, for the avoidance of doubt, to or for the benefit of any Obligor, that Agent is not a fiduciary with respect to the assets of such Lender involved in its entrance into,
participation in, administration of and performance of the Loans, Letters of Credit, Commitments and Loan Documents (including in connection with the reservation or exercise of any rights by Agent under any Loan Document). 

12.15. No Third Party Beneficiaries. This Section 12 is an agreement solely among Secured
Parties and Agent, and shall survive Full Payment of the Obligations. Other than Section 12.8.1(b), this Section 12 does not confer any rights or benefits upon Borrowers or any other Person. As
between Borrowers and Agent, any action that Agent may take under any Loan Documents or with respect to any Obligations shall be conclusively presumed to have been authorized and directed by Secured Parties. 

SECTION 13. BENEFIT OF AGREEMENT; ASSIGNMENTS 

13.1. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of Obligors, Agent,
Lenders, Secured Parties, and their respective successors and assigns, except that (a) no Obligor shall have the right to assign its rights or delegate its obligations under any Loan Documents (except in connection with a transaction permitted
under Section 10.2.8); and (b) any assignment by a Lender must be made in compliance with Section 13.3. Agent may treat the Person which made any Loan as the owner thereof for all purposes
until such Person makes an assignment in accordance with Section 13.3. Any authorization or consent of a Lender shall be conclusive and binding on any subsequent transferee or assignee of such Lender. 

13.2. Participations. 

13.2.1. Permitted Participants; Effect. Subject to Section 13.3.3, any Lender may sell to a financial
institution (“Participant”) a participating interest in the rights and obligations of such Lender under any Loan Documents. Despite any sale by a Lender of participating interests to a Participant, such Lender’s obligations
under the Loan Documents shall remain unchanged, it shall remain solely responsible to the other parties hereto for performance of such obligations, it shall remain the holder of its Loans and Commitments for all purposes, all amounts payable by
Borrowers shall be determined as if it had not sold such participating interests, and Borrowers and Agent shall continue to deal solely and directly with such Lender in connection with the Loan Documents. Each Lender shall be solely responsible for
notifying its Participants of any matters under the Loan Documents, and Agent and the other Lenders shall not have any obligation or liability to any such Participant. A Participant that would be a Foreign Lender if it were a Lender shall not be
entitled to the benefits of Section 5.9 unless Borrowers agree otherwise in writing. 

  
 -111- 

 13.2.2. Voting Rights. Each Lender shall retain the sole right to approve, without
the consent of any Participant, any amendment, waiver or other modification of a Loan Document other than that which forgives principal, interest or fees, reduces the stated interest rate or fees payable with respect to any Loan or Commitment in
which such Participant has an interest, postpones the Commitment Termination Date or any date fixed for any regularly scheduled payment of principal, interest or fees on such Loan or Commitment, or releases any Borrower, Guarantor or substantially
all Collateral. 
 13.2.3. Participant Register. Each Lender that sells a participation shall, acting as a non-fiduciary agent of Borrowers (solely for tax purposes), maintain a register in which it enters the Participant’s name, address and interest in Commitments, Loans (and stated interest) and LC Obligations.
Entries in the register shall be conclusive, absent manifest error, and such Lender shall treat each Person recorded in the register as the owner of the participation for all purposes, notwithstanding any notice to the contrary. No Lender shall have
an obligation to disclose any information in such register except to the extent necessary to establish that a Participant’s interest is in registered form under the Code. 

13.2.4. Benefit of Set-Off. Obligors agree that each Participant shall have a right of set-off in respect of its participating interest to the same extent as if such interest were owing directly to a Lender, and each Lender shall also retain the right of set-off
with respect to any participating interests sold by it. By exercising any right of set-off, a Participant agrees to share with Lenders all amounts received through its
set-off, in accordance with Section 12.5 as if such Participant were a Lender. 

13.3. Assignments. 

13.3.1. Permitted Assignments. A Lender may assign to an Eligible Assignee any of its rights and obligations under the Loan Documents,
as long as (a) each assignment is of a constant, and not a varying, percentage of the transferor Lender’s rights and obligations under the Loan Documents and, in the case of a partial assignment (other than partial assignments to an
Affiliate of such Lender), is in a minimum principal amount of $5,000,000 (unless otherwise agreed by Agent in its discretion) and integral multiples of $1,000,000 in excess of that amount; (b) except in the case of an assignment in whole of a
Lender’s rights and obligations or an assignment to an Affiliate of such Lender, the aggregate amount of the Commitments retained by the transferor Lender is at least $5,000,000 (unless otherwise agreed by Agent in its discretion); and
(c) the parties to each such assignment shall execute and deliver to Agent, for its acceptance and recording, an Assignment and Acceptance. Nothing herein shall limit the right of a Lender to pledge or assign any rights under the Loan Documents
to secure obligations of such Lender, including a pledge or assignment to a Federal Reserve Bank; provided, however, that no such pledge or assignment shall release the Lender from its obligations hereunder nor substitute the pledge or
assignee for such Lender as a party hereto. 

  
 -112- 

 13.3.2. Effect; Effective Date. Upon delivery to Agent of an assignment notice in the
form of Exhibit B and a processing fee of $3,500 (unless such assignment is to an Affiliate of such Lender or is otherwise agreed by Agent in its discretion), the assignment shall become effective as specified in the notice, if it complies with this
Section 13.3. From such effective date, the Eligible Assignee shall for all purposes be a Lender under the Loan Documents, and shall have all rights and obligations of a Lender thereunder. Upon consummation of an
assignment, the transferor Lender, Agent and Borrowers shall make appropriate arrangements for issuance of replacement and/or new notes, if applicable. The transferee Lender shall comply with Section 5.9 and deliver, upon
request, an administrative questionnaire satisfactory to Agent. 
 13.3.3. Certain Assignees. No assignment or participation may be
made to an Obligor, Affiliate of an Obligor, Defaulting Lender or natural person. Agent shall have no obligation to determine whether any assignment is permitted under the Loan Documents. Any assignment by a Defaulting Lender shall be effective only
upon payment by the Eligible Assignee or Defaulting Lender to Agent of an aggregate amount sufficient, upon distribution (through direct payment, purchases of participations or other compensating actions as Agent deems appropriate), to satisfy all
funding and payment liabilities then owing by the Defaulting Lender hereunder. If an assignment by a Defaulting Lender shall become effective under Applicable Law for any reason without compliance with the foregoing sentence, then the assignee shall
be deemed a Defaulting Lender for all purposes until such compliance occurs. 
 13.3.4. Register. Agent, acting as a non-fiduciary agent of Borrowers (solely for tax purposes), shall maintain (a) a copy (or electronic equivalent) of each Assignment and Acceptance delivered to it, and (b) a register for recordation of the
names, addresses and Commitments of, and the Loans, interest and LC Obligations owing to, each Lender. Entries in the register shall be conclusive, absent manifest error, and Borrowers, Agent and Lenders shall treat each lender recorded in such
register as a Lender for all purposes under the Loan Documents, notwithstanding any notice to the contrary. Agent may choose to show only one Borrower as the borrower in the register, without any effect on the liability of any Obligor with respect
to the Obligations. The register shall be available for inspection by Borrowers or any Lender, from time to time upon reasonable notice. 

13.4. Replacement of Certain Lenders. If a Lender (a) fails to give its consent to any amendment, waiver or
action for which consent of all Lenders was required and Required Lenders consented, or (b) is a Defaulting Lender, then, in addition to any other rights and remedies that any Person may have, Agent or Borrower Agent may, by notice to such
Lender within 120 days after such event, require such Lender to assign all of its rights and obligations under the Loan Documents to Eligible Assignee(s), pursuant to appropriate Assignment and Acceptance(s), within 20 days after the notice. Agent
is irrevocably appointed as attorney-in-fact to execute any such Assignment and Acceptance if the Lender fails to execute it. Such Lender shall be entitled to receive,
in cash, concurrently with such assignment, all amounts owed to it under the Loan Documents through the date of assignment. 
 SECTION 14. GUARANTY

 14.1. Guaranty of the Obligations. Subject to the provisions of Section 14.2,
Guarantors jointly and severally hereby irrevocably and unconditionally guaranty to Agent and Lenders the due and punctual payment in full of all Obligations (other than Excluded Swap Obligations) when the same shall become due, whether at stated
maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code) (collectively, the
“Guaranteed Obligations”). 

  
 -113- 

 14.2. Contribution by Guarantors. All Guarantors desire to
allocate among themselves (collectively, the “Contributing Guarantors”), in a fair and equitable manner, their obligations arising under this Guaranty. Accordingly, in the event any payment or distribution is made on any date by a
Guarantor (a “Funding Guarantor”) under this Guaranty such that its Aggregate Payments exceeds its Fair Share as of such date, such Funding Guarantor shall be entitled to a contribution from each of the other Contributing Guarantors
in an amount sufficient to cause each Contributing Guarantor’s Aggregate Payments to equal its Fair Share as of such date. “Fair Share” means, with respect to a Contributing Guarantor as of any date of determination, an amount
equal to (a) the ratio of (i) the Fair Share Contribution Amount with respect to such Contributing Guarantor, to (ii) the aggregate of the Fair Share Contribution Amounts with respect to all Contributing Guarantors multiplied by,
(b) the aggregate amount paid or distributed on or before such date by all Funding Guarantors under this Guaranty in respect of the obligations guaranteed. “Fair Share Contribution Amount” means, with respect to a Contributing
Guarantor as of any date of determination, the maximum aggregate amount of the obligations of such Contributing Guarantor under this Guaranty that would not render its obligations hereunder subject to avoidance as a fraudulent transfer or conveyance
under Section 548 of Title 11 of the United States Code or any comparable applicable provisions of state law; provided, solely for purposes of calculating the “Fair Share Contribution Amount” with respect to any
Contributing Guarantor for purposes of this Section 14.2, any assets or liabilities of such Contributing Guarantor arising by virtue of any rights to subrogation, reimbursement or indemnification or any rights to or
obligations of contribution hereunder shall not be considered as assets or liabilities of such Contributing Guarantor. “Aggregate Payments” means, with respect to a Contributing Guarantor as of any date of determination, an amount
equal to (1) the aggregate amount of all payments and distributions made on or before such date by such Contributing Guarantor in respect of this Guaranty (including, without limitation, in respect of this
Section 14.2), minus (2) the aggregate amount of all payments received on or before such date by such Contributing Guarantor from the other Contributing Guarantors as contributions under this
Section 14.2. The amounts payable as contributions hereunder shall be determined as of the date on which the related payment or distribution is made by the applicable Funding Guarantor. The allocation among Contributing
Guarantors of their obligations as set forth in this Section 14.2 shall not be construed in any way to limit the liability of any Contributing Guarantor hereunder. Each Guarantor is a third-party beneficiary to the
contribution agreement set forth in this Section 14.2. 
 14.3. Payment by Guarantors.
Subject to Section 14.2, Guarantors hereby jointly and severally agree, in furtherance of the foregoing and not in limitation of any other right which Lender may have at law or in equity against any Guarantor by virtue
hereof, that upon the failure of any Borrower to pay any of the Guaranteed Obligations when and as the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that
would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code), Guarantors will upon demand pay, or cause to be paid, in cash, to Agent, for the benefit of itself and the Lenders, an amount equal to
the sum of the unpaid principal amount of all Guaranteed Obligations then due as aforesaid, accrued and unpaid interest on such Guaranteed Obligations (including interest which, but for any Borrower’s becoming the subject of a case under the
Bankruptcy Code, would have accrued on such Guaranteed Obligations, whether or not a claim is allowed against such Borrower for such interest in the related bankruptcy case) and all other Guaranteed Obligations then owed to Agent and Lenders as
aforesaid. 

  
 -114- 

 14.4. Liability of Guarantors Absolute. Each Guarantor agrees that its
obligations hereunder are irrevocable, absolute, independent and unconditional and shall not be affected by any circumstance which constitutes a legal or equitable discharge of a guarantor or surety other than payment in full of the Guaranteed
Obligations. In furtherance of the foregoing and without limiting the generality thereof, each Guarantor agrees as follows: 
 14.4.1. this
Guaranty is a guaranty of payment when due and not of collectability. This Guaranty is a primary obligation of each Guarantor and not merely a contract of surety; 

14.4.2. Agent may enforce this Guaranty upon the occurrence of an Event of Default notwithstanding the existence of any dispute between any
Borrower and Agent or any Lender with respect to the existence of such Event of Default; 
 14.4.3. the obligations of each Guarantor
hereunder are independent of the obligations of Borrowers and the obligations of any other guarantor (including any other Guarantor) of the obligations of Borrowers, and a separate action or actions may be brought and prosecuted against such
Guarantor whether or not any action is brought against any Borrower or any of such other guarantors and whether or not any Borrower is joined in any such action or actions; 

14.4.4. payment by any Guarantor of a portion, but not all, of the Guaranteed Obligations shall in no way limit, affect, modify or abridge any
Guarantor’s liability for any portion of the Guaranteed Obligations which has not been paid. Without limiting the generality of the foregoing, if Agent or any Lender is awarded a judgment in any suit brought to enforce any Guarantor’s
covenant to pay a portion of the Guaranteed Obligations, such judgment shall not be deemed to release such Guarantor from its covenant to pay the portion of the Guaranteed Obligations that is not the subject of such suit, and such judgment shall
not, except to the extent satisfied by such Guarantor, limit, affect, modify or abridge any other Guarantor’s liability hereunder in respect of the Guaranteed Obligations; 

14.4.5. Agent and/or Lenders, upon such terms as they deem appropriate, without notice or demand and without affecting the validity or
enforceability hereof or giving rise to any reduction, limitation, impairment, discharge or termination of any Guarantor’s liability hereunder, from time to time may (i) renew, extend, accelerate, increase the rate of interest on, or
otherwise change the time, place, manner or terms of payment of the Guaranteed Obligations; (ii) settle, compromise, release or discharge, or accept or refuse any offer of performance with respect to, or substitutions for, the Guaranteed
Obligations or any agreement relating thereto and/or subordinate the payment of the same to the payment of any other obligations; (iii) request and accept other guaranties of the Guaranteed Obligations and take and hold security for the payment
hereof or the Guaranteed Obligations; (iv) release, surrender, exchange, substitute, compromise, settle, rescind, waive, alter, subordinate or modify, with or without consideration, any security for payment of the Guaranteed Obligations, any
other guaranties of the Guaranteed Obligations, or any other obligation of any Person (including any other Guarantor) with respect to the Guaranteed Obligations; (v) enforce and apply any security now or hereafter held by or for the benefit of
Agent for the benefit of itself and the Lenders in respect hereof or the Guaranteed Obligations and direct the order or manner of sale thereof, or exercise any other right or remedy that Agent may have against any such security, in each case as
Agent in its discretion may determine consistent herewith or any 

  
 -115- 

 
applicable security agreement, including foreclosure on any such security pursuant to one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially
reasonable, and even though such action operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of any Guarantor against any Borrower or any security for the Guaranteed Obligations; and (vi) exercise
any other rights available to it under the Loan Documents; and 
 14.4.6. this Guaranty and the obligations of Guarantors hereunder shall be
valid and enforceable and shall not be subject to any reduction, limitation, impairment, discharge or termination for any reason (other than payment in full of the Guaranteed Obligations), including the occurrence of any of the following, whether or
not any Guarantor shall have had notice or knowledge of any of them: (i) any failure or omission to assert or enforce or agreement or election not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or
otherwise, of the exercise or enforcement of, any claim or demand or any right, power or remedy (whether arising under the Loan Documents, at law, in equity or otherwise) with respect to the Guaranteed Obligations or any agreement relating thereto,
or with respect to any other guaranty of or security for the payment of the Guaranteed Obligations; (ii) any rescission, waiver, amendment or modification of, or any consent to departure from, any of the terms or provisions (including
provisions relating to events of default) hereof, any of the other Loan Documents or any agreement or instrument executed pursuant thereto, or of any other guaranty or security for the Guaranteed Obligations, in each case whether or not in
accordance with the terms hereof or such Loan Document, or any agreement relating to such other guaranty or security; (iii) the Guaranteed Obligations, or any agreement relating thereto, at any time being found to be illegal, invalid or
unenforceable in any respect; (iv) the application of payments received from any source (other than payments received pursuant to the other Loan Documents or from the proceeds of any security for the Guaranteed Obligations, except to the extent
such security also serves as collateral for indebtedness other than the Guaranteed Obligations) to the payment of indebtedness other than the Guaranteed Obligations, even though Agent or Lenders might have elected to apply such payment to any part
or all of the Guaranteed Obligations; (v) Agent’s or Lenders’ consent to the change, reorganization or termination of the corporate structure or existence of US Concrete or any of its Subsidiaries and to any corresponding
restructuring of the Guaranteed Obligations; (vi) any failure to perfect or continue perfection of a security interest in any collateral which secures any of the Guaranteed Obligations; (vii) any defenses,
set-offs or counterclaims which any Borrower may allege or assert against Agent or any Lender in respect of the Guaranteed Obligations, including failure of consideration, breach of warranty, payment, statute
of frauds, statute of limitations, accord and satisfaction and usury; and (viii) any other act or thing or omission, or delay to do any other act or thing, which may or might in any manner or to any extent vary the risk of any Guarantor as an
Obligor in respect of the Guaranteed Obligations. 
 14.5. Waivers by Guarantors. Each Guarantor hereby waives,
for the benefit of Agent and each Lender: (a) any right to require Agent or any Lender, as a condition of payment or performance by such Guarantor, to (i) proceed against any Borrower, any other guarantor (including any other Guarantor) of
the Guaranteed Obligations or any other Person, (ii) proceed against or exhaust any security held from any Borrower, any such other guarantor or any other Person, (iii) proceed against or have resort to any balance of any Deposit Account,
Securities Account or Commodities Account or credit on the books of Agent or any Lender in favor of any Borrower or any other Person, or (iv) pursue any other remedy in the power of Agent or any Lender whatsoever; (b) any defense arising
by reason of the incapacity, lack of authority or any disability or other defense of any Borrower or any other Guarantor including any defense based on or arising 

  
 -116- 

 
out of the lack of validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of any Borrower or
any other Guarantor from any cause other than payment in full of the Guaranteed Obligations; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other
respects more burdensome than that of the principal; (d) any defense based upon Agent’s or any Lender’s errors or omissions in the administration of the Guaranteed Obligations, except behavior which amounts to bad faith;
(e) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms hereof and any legal or equitable discharge of such Guarantor’s obligations hereunder, (ii) the benefit of any
statute of limitations affecting such Guarantor’s liability hereunder or the enforcement hereof, (iii) any rights to set-offs, recoupments and counterclaims, and (iv) promptness, diligence and
any requirement that Agent or any Lender protect, secure, perfect or insure any security interest or lien or any property subject thereto; (f) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any
action or inaction, including acceptance hereof, notices of default hereunder or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Guaranteed Obligations or any agreement related thereto, notices
of any extension of credit to Borrowers and notices of any of the matters referred to in Section 14.4 and any right to consent to any thereof; and (g) any defenses or benefits that may be derived from or afforded by
law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof other than Full Payment of the Obligations. 

14.6. Guarantors’ Rights of Subrogation, Contribution, etc. Until the Guaranteed
Obligations shall have been indefeasibly paid in full and the Commitments shall have terminated and all Letters of Credit shall have expired or been cancelled, each Guarantor hereby waives any claim, right or remedy, direct or indirect, that such
Guarantor now has or may hereafter have against any Borrower or any other Guarantor or any of its assets in connection with this Guaranty or the performance by such Guarantor of its obligations hereunder, in each case whether such claim, right or
remedy arises in equity, under contract, by statute, under common law or otherwise and including without limitation (a) any right of subrogation, reimbursement or indemnification that such Guarantor now has or may hereafter have against any
Borrower with respect to the Guaranteed Obligations, (b) any right to enforce, or to participate in, any claim, right or remedy that Agent or any Lender now has or may hereafter have against any Borrower, and (c) any benefit of, and any
right to participate in, any collateral or security now or hereafter held by Agent or any Lender. In addition, until the Guaranteed Obligations shall have been indefeasibly paid in full and the Commitment shall have terminated and all Letters of
Credit shall have expired or been cancelled, each Guarantor shall withhold exercise of any right of contribution such Guarantor may have against any other guarantor (including any other Guarantor) of the Guaranteed Obligations, including, without
limitation, any such right of contribution as contemplated by Section 14.2. Each Guarantor further agrees that, to the extent the waiver or agreement to withhold the exercise of its rights of subrogation, reimbursement,
indemnification and contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation, reimbursement or indemnification such Guarantor may have against any Borrower or
against any collateral or security, and any rights of contribution such Guarantor may have against any such other guarantor, shall be junior and subordinate to any rights Agent or any Lender may have against any Borrower, to all right, title and
interest Lender may have in any such collateral or security, and to any right Agent or any Lender may have against such other guarantor. If any amount shall be paid to any Guarantor on account of any such subrogation, reimbursement, indemnification
or contribution rights at any time when all Guaranteed Obligations shall not have been finally and indefeasibly paid in full, such amount shall be held in trust for Agent and Lenders and shall forthwith be paid over to Agent to be credited and
applied against the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms hereof. 

  
 -117- 

 14.7. Subordination of Other Obligations. Any indebtedness of
any Borrower or any Guarantor now or hereafter held by any Guarantor (the “Obligee Guarantor”) is hereby subordinated in right of payment to the Guaranteed Obligations, and any such indebtedness collected or received by the Obligee
Guarantor after an Event of Default has occurred and is continuing shall be held in trust for Agent and Lenders and shall forthwith be paid over to Agent to be credited and applied against the Guaranteed Obligations but without affecting, impairing
or limiting in any manner the liability of the Obligee Guarantor under any other provision hereof. 
 14.8. Continuing
Guaranty. This Guaranty is a continuing guaranty and shall remain in effect until all of the Guaranteed Obligations shall have been indefeasibly paid in full and the Commitment shall have terminated and all Letters of Credit shall
have expired or been cancelled. Each Guarantor hereby irrevocably waives any right to revoke this Guaranty as to future transactions giving rise to any Guaranteed Obligations. 

14.9. Authority of Guarantors or Borrowers. It is not necessary for Agent or any Lender to inquire
into the capacity or powers of any Guarantor or any Borrower or the officers, directors or any agents acting or purporting to act on behalf of any of them. 

14.10. Financial Condition of Borrowers. Any Loan may be made to Borrowers or continued from time to
time, without notice to or authorization from any Guarantor regardless of the financial or other condition of Borrowers at the time of any such grant or continuation. Neither Agent nor any Lender shall have any obligation to disclose or discuss with
any Guarantor its assessment, or any Guarantor’s assessment, of the financial condition of any Borrower. Each Guarantor has adequate means to obtain information from each Borrower on a continuing basis concerning the financial condition of such
Borrower and its ability to perform its obligations under the Loan Documents, and each Guarantor assumes the responsibility for being and keeping informed of the financial condition of Borrowers and of all circumstances bearing upon the risk of
nonpayment of the Guaranteed Obligations. Each Guarantor hereby waives and relinquishes any duty on the part of Agent or any Lender to disclose any matter, fact or thing relating to the business, operations or conditions of any Borrower now known or
hereafter known by Agent or any Lender. 
 14.11. Bankruptcy, etc. So long as any Guaranteed Obligations remain
outstanding, no Guarantor shall, without the prior written consent of Agent, commence or join with any other Person in commencing any bankruptcy, reorganization or insolvency case or proceeding of or against any Borrower or any other Guarantor. 

14.11.1. The obligations of Guarantors hereunder shall not be reduced, limited, impaired, discharged, deferred, suspended or terminated by any
case or proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of any Borrower or any other Guarantor or by any defense which any Borrower or any other Guarantor may have
by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding. 
 14.11.2. Each Guarantor
acknowledges and agrees that any interest on any portion of the Guaranteed Obligations which accrues after the commencement of any case or proceeding referred to in Section 14.11.1 above (or, if interest on any portion of
the Guaranteed Obligations 

  
 -118- 

 
ceases to accrue by operation of law by reason of the commencement of such case or proceeding, such interest as would have accrued on such portion of the Guaranteed Obligations if such case or
proceeding had not been commenced) shall be included in the Guaranteed Obligations because it is the intention of Guarantors and Agent and Lenders that the Guaranteed Obligations which are guaranteed by Guarantors pursuant hereto should be
determined without regard to any rule of law or order which may relieve any Borrower of any portion of such Guaranteed Obligations. Guarantors will permit any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit of
creditors or similar person to pay Agent and Lenders, or allow the claim of Agent and Lenders in respect of, any such interest accruing after the date on which such case or proceeding is commenced. 

14.11.3. In the event that all or any portion of the Guaranteed Obligations are paid by any Borrower or any Guarantor, the obligations of
Guarantors hereunder shall continue and remain in full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) are rescinded or recovered directly or indirectly from Agent or any Lender as a
preference, fraudulent transfer or otherwise, and any such payments which are so rescinded or recovered shall constitute Guaranteed Obligations for all purposes hereunder. 

SECTION 15. MISCELLANEOUS 
 15.1.
Consents, Amendments and Waivers. 
 15.1.1. Amendment. No modification of any Loan Document, including any extension or
amendment of a Loan Document or any waiver of a Default or Event of Default, shall be effective without the prior written agreement of Required Lenders (or Agent at the written direction of Required Lenders) and each Obligor party to such Loan
Document; provided, however, that 
 (a) without the prior written consent of Agent, no modification shall be effective with
respect to any provision in a Loan Document that relates to any rights, duties or discretion of Agent; 
 (b) without the prior written
consent of Issuing Bank, no modification shall be effective with respect to any LC Obligations or any other provision in a Loan Document that relates to any rights, duties or discretion of Issuing Bank; 

(c) without the prior written consent of each affected Lender, including a Defaulting Lender, no modification shall be effective that would
(i) increase the Commitment of such Lender; (ii) reduce the amount of, or waive or delay payment of, any principal, interest, fees or other amounts payable to such Lender (except as provided in Section 4.2);
(iii) extend the Revolver Termination Date applicable to such Lender’s Obligations; or (iv) amend this clause (c); 
 (d)
without the prior written consent of all Lenders (except any Defaulting Lender), no modification shall be effective that would (i) alter Section 5.5.2 (or otherwise have the effect of altering the application of
payments thereunder), 7.1 (except to add Collateral), 12.5 (or otherwise have the effect of altering the pro rata sharing of payments) or 15.1.1; (ii) amend the definition of Borrowing Base (or any defined term used in such
definition), Pro Rata or Required Lenders; (iii) increase any advance rate or decrease the Availability Reserve; (iv) release all or substantially all Collateral or subordinate Agent’s Lien on all or substantially all of the
Collateral; or (v) except in connection with a merger, disposition or similar transaction expressly permitted hereby, release any Obligor from liability for any Obligations; and 

  
 -119- 

 (e) without the prior written consent of a Secured Bank Product Provider, no modification
shall be effective that affects its relative payment priority under Section 5.5.2. 
 15.1.2. Limitations.
The agreement of Obligors shall not be necessary to the effectiveness of any modification of a Loan Document that deals solely with the rights and duties of Lenders, Agent and/or Issuing Bank as among themselves. Only the consent of the parties to
any agreement relating to fees or a Bank Product shall be required for modification of such agreement, and no Bank Product provider (in such capacity) shall have any right to consent to modification of any Loan Document other than its Bank Product
agreement. Any waiver or consent granted by Agent, Issuing Bank or Lenders hereunder shall be effective only if in writing and only for the matter specified. Notwithstanding Section 15.1.1, any amendments that Agent deems
appropriate in connection with an increase in Revolver Commitments pursuant to Section 2.1.7 shall not require the consent of any Lender (other than Lenders that are increasing their Revolver Commitments at such time). 

15.1.3. Payment for Consents. No Obligor will, directly or indirectly, pay any remuneration or other thing of value, whether by way of
additional interest, fee or otherwise, to any Lender (in its capacity as a Lender hereunder) as consideration for agreement by such Lender with any modification of any Loan Documents, unless such remuneration or value is concurrently paid, on the
same terms, on a Pro Rata basis to all Lenders providing their consent. 
 15.2. Indemnity. EACH OBLIGOR SHALL INDEMNIFY AND HOLD
HARMLESS THE INDEMNITEES AGAINST ANY CLAIMS THAT MAY BE INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE, INCLUDING CLAIMS ASSERTED BY ANY OBLIGOR OR OTHER PERSON OR ARISING FROM THE NEGLIGENCE OF AN INDEMNITEE; PROVIDED THAT, IN NO EVENT SHALL ANY
PARTY TO A LOAN DOCUMENT HAVE ANY OBLIGATION THEREUNDER TO INDEMNIFY OR HOLD HARMLESS AN INDEMNITEE WITH RESPECT TO A CLAIM THAT IS DETERMINED IN A NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION
TO RESULT FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE. 
 15.3. Notices and Communications.

 15.3.1. Notice Address. Subject to Section 4.1.4, all notices and other communications by or to a
party hereto shall be in writing and shall be given to any Obligor, at Borrower Agent’s address shown on the signature pages hereof, and to any other Person at its address shown on the signature pages hereof (or, in the case of a Person who
becomes a Lender after the Closing Date, at the address shown on its Assignment and Acceptance), or at such other address as a party may hereafter specify by notice in accordance with this Section 15.3. Each communication
shall be effective only (a) if given by facsimile transmission, when transmitted to the applicable facsimile number, if confirmation of receipt is received; (b) if given by mail, three Business Days after deposit in the U.S. mail, with
first-class postage pre-paid, addressed to the applicable address; or (c) if given by personal delivery (including overnight or courier service), when duly delivered to the notice address with receipt
acknowledged. Notwithstanding the 

  
 -120- 

 
foregoing, no notice to Agent pursuant to Section 2.1.4, 3.1.2, 4.1.1 or 4.3 shall be effective until actually received by the individual to whose attention at
Agent such notice is required to be sent. Any written communication that is not sent in conformity with the foregoing provisions shall nevertheless be effective on the date actually received by the noticed party. Any notice received by Borrower
Agent shall be deemed received by all Obligors. 
 15.3.2. Electronic Communications; Voice Mail. Electronic mail and internet
websites may be used only for routine communications, such as delivery of Borrower Materials, administrative matters, distribution of Loan Documents, and matters permitted under Section 4.1.4. Agent and Lenders make no
assurances as to the privacy and security of electronic communications. Electronic and voice mail may not be used as effective notice under the Loan Documents. 

15.3.3. Platform. Borrower Materials shall be delivered pursuant to procedures approved by Agent, including electronic delivery (if
possible) upon request by Agent to an electronic system maintained by Agent (“Platform”). Borrowers shall notify Agent of each posting of Borrower Materials on the Platform and the materials shall be deemed received by Agent only
upon its receipt of such notice. Borrower Materials and other information relating to this credit facility may be made available to Lenders on the Platform. The Platform is provided “as is” and “as available.” Agent does not
warrant the accuracy or completeness of any information on the Platform nor the adequacy or functioning of the Platform, and expressly disclaims liability for any errors or omissions in the Borrower Materials or any issues involving the Platform. NO
WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS, OR FREEDOM FROM VIRUSES OR OTHER CODE
DEFECTS, IS MADE BY AGENT WITH RESPECT TO BORROWER MATERIALS OR THE PLATFORM. Obligors and Lenders acknowledge that “public” information may not be segregated from material non-public information on
the Platform. Lenders acknowledge that Borrower Materials may include material non-public information of Obligors and should not be made available to any personnel who do not wish to receive such information
or who may be engaged in investment or other market-related activities with respect to any Obligor’s securities. No Agent Indemnitee shall have any liability to Obligors, Lenders or any other Person for losses, claims, damages, liabilities or
expenses of any kind (whether in tort, contract or otherwise) relating to use by any Person of the Platform, including any unintended recipient, nor for delivery of Borrower Materials and other information through the Platform, internet, e-mail or any other electronic platform or messaging system. 
 15.3.4.
Non-Conforming Communications. Agent and Lenders may rely upon any communications purportedly given by or on behalf of any Obligor even if they were not made in a manner specified herein, were
incomplete or were not confirmed, or if the terms thereof, as understood by the recipient, varied from a later confirmation. Each Obligor shall indemnify and hold harmless each Indemnitee from any liabilities, losses, costs and expenses arising from
any electronic or telephonic communication purportedly given by or on behalf of a Obligor. 
 15.4. Performance of
Obligors’ Obligations. Agent may, in its Permitted Discretion at any time and from time to time, at Borrowers’ expense, pay any amount or do any act required of an Obligor under any Loan Documents
or otherwise lawfully requested by Agent to (a) enforce any Loan Documents or collect any Obligations; (b) protect, insure, maintain or realize upon any Collateral; or (c) defend or maintain the validity or priority of Agent’s
Liens in any Collateral, including any payment of a judgment, insurance premium, warehouse charge, finishing or 

  
 -121- 

 
processing charge, or landlord claim, or any discharge of a Lien. All payments, costs and expenses (including Extraordinary Expenses) of Agent under this Section shall be reimbursed to Agent by
Borrowers, within five days after demand, with interest from the date incurred until paid in full, at the Default Rate applicable to Base Rate Revolver Loans. Any payment made or action taken by Agent under this Section shall be without prejudice to
any right to assert an Event of Default or to exercise any other rights or remedies under the Loan Documents. 
 15.5. Credit
Inquiries. Agent and Lenders may (but shall have no obligation) to respond to usual and customary credit inquiries from third parties concerning any Obligor or Subsidiary. 

15.6. Severability. Wherever possible, each provision of the Loan Documents shall be interpreted in such manner as
to be valid under Applicable Law. If any provision is found to be invalid under Applicable Law, it shall be ineffective only to the extent of such invalidity and the remaining provisions of the Loan Documents shall remain in full force and effect.

 15.7. Cumulative Effect; Conflict of Terms. The provisions of the Loan Documents are cumulative. The parties
acknowledge that the Loan Documents may use several limitations or measurements to regulate similar matters, and they agree that these are cumulative and that each must be performed as provided. Except as otherwise provided in another Loan Document
(by specific reference to the applicable provision of this Agreement), if any provision contained herein is in direct conflict with any provision in another Loan Document, the provision herein shall govern and control. 

15.8. Counterparts; Electronic Signatures. 

15.8.1. Any Loan Document may be executed in counterparts, each of which shall constitute an original, but all of which when taken together
shall constitute a single contract. This Agreement shall become effective when Agent has received counterparts bearing the signatures of all parties hereto. Delivery of a signature page of any Loan Document by telecopy or other electronic means
shall be effective as delivery of a manually executed counterpart of such agreement. 
 15.8.2. This Agreement and any document, amendment,
approval, consent, information, notice, certificate, request, statement, disclosure or authorization related to this Agreement (each a “Communication”), including Communications required to be in writing, may be in the form of an
Electronic Record and may be executed using Electronic Signatures. Each of the Obligors agrees that any Electronic Signature on or associated with any Communication shall be valid and binding on each of the Obligors to the same extent as a manual,
original signature, and that any Communication entered into by Electronic Signature, will constitute the legal, valid and binding obligation of each of the Obligors enforceable against such in accordance with the terms thereof to the same extent as
if a manually executed original signature was delivered. Any Communication may be executed in as many counterparts as necessary or convenient, including both paper and electronic counterparts, but all such counterparts are one and the same
Communication. For the avoidance of doubt, the authorization under this paragraph may include, without limitation, use or acceptance by Agent and each of the Secured Parties of a manually signed paper Communication which has been converted into
electronic form (such as scanned into PDF format), or an electronically signed Communication converted into another format, for transmission, delivery and/or retention. Agent and each of the Secured Parties may, at its option, create one or more
copies of any Communication in the form of an imaged Electronic Record 

  
 -122- 

 
(“Electronic Copy”), which shall be deemed created in the ordinary course of such Person’s business, and destroy the original paper document. All Communications in the
form of an Electronic Record, including an Electronic Copy, shall be considered an original for all purposes, and shall have the same legal effect, validity and enforceability as a paper record. Notwithstanding anything contained herein to the
contrary, Agent is under no obligation to accept an Electronic Signature in any form or in any format unless expressly agreed to by Agent at its sole option pursuant to procedures approved by it; provided, further, without limiting the foregoing,
(a) to the extent Agent has agreed to accept such Electronic Signature, Agent and each of the Secured Parties shall be entitled to rely on any such Electronic Signature purportedly given by or on behalf of any Obligor without further
verification and (b) upon the request of Agent or any Secured Party, any Electronic Signature shall be promptly followed by such manually executed counterpart. For purposes hereof, “Electronic Record” and
“Electronic Signature” shall have the meanings assigned to them, respectively, by 15 USC §7006, as it may be amended from time to time. 

15.9. Entire Agreement. Time is of the essence with respect to all Loan Documents and Obligations. The Loan
Documents constitute the entire agreement, and supersede all prior understandings and agreements, among the parties relating to the subject matter thereof. 

15.10. Relationship with Lenders. The obligations of each Lender hereunder are several, and no Lender shall be
responsible for the obligations or Commitments of any other Lender. Amounts payable hereunder to each Lender shall be a separate and independent debt. It shall not be necessary for Agent or any other Lender to be joined as an additional party in any
proceeding for such purposes. Nothing in this Agreement and no action of Agent, Lenders or any other Secured Party pursuant to the Loan Documents or otherwise shall be deemed to constitute Agent and any Secured Party to be a partnership, joint
venture or similar arrangement, nor to constitute control of any Obligor. 
 15.11. No Advisory or Fiduciary
Responsibility. In connection with all aspects of each transaction contemplated by any Loan Document, Obligors acknowledge and agree that (a)(i) this credit facility and any related arranging or other services by Agent, any
Lender, any of their Affiliates or any arranger are arm’s-length commercial transactions between Obligors and such Person; (ii) Obligors have consulted their own legal, accounting, regulatory and tax
advisors to the extent they have deemed appropriate; and (iii) Obligors are capable of evaluating, and understand and accept, the terms, risks and conditions of the transactions contemplated by the Loan Documents; (b) each of Agent,
Lenders, their Affiliates and any arranger is and has been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary for Obligors,
any of their Affiliates or any other Person, and has no obligation with respect to the transactions contemplated by the Loan Documents except as expressly set forth therein; and (c) Agent, Lenders, their Affiliates and any arranger may be
engaged in a broad range of transactions that involve interests that differ from those of Obligors and their Affiliates, and have no obligation to disclose any of such interests to Obligors or their Affiliates. To the fullest extent permitted by
Applicable Law, each Obligor hereby waives and releases any claims that it may have against Agent, Lenders, their Affiliates and any arranger with respect to any breach of agency or fiduciary duty in connection with any transaction contemplated by a
Loan Document. 

  
 -123- 

 15.12. Confidentiality. Each of Agent, Lenders and Issuing Bank
shall maintain the confidentiality of all Information (as defined below), except that Information may be disclosed (a) to its Affiliates, and to its and their partners, directors, officers, employees, agents, advisors and representatives
(provided such Persons are informed of the confidential nature of the Information and instructed to keep it confidential); (b) to the extent requested by any governmental, regulatory or self-regulatory authority purporting to have jurisdiction
over it or its Affiliates; (c) to the extent required by Applicable Law or by any subpoena or other legal process; (d) to any other party hereto; (e) in connection with the exercise of any remedies hereunder or under any other Loan
Document or any action or proceeding relating to any Loan Documents or Obligations; (f) subject to an agreement containing provisions substantially the same as this Section, to any Transferee or any actual or prospective party (or its advisors)
to any Bank Product; (g) with the consent of Borrower Agent; or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) is available to Agent, any Lender,
Issuing Bank or any of their Affiliates on a nonconfidential basis from a source other than Obligors that has not obtained such information in breach of this Section. Notwithstanding the foregoing, Agent and Lenders may publish or disseminate
general information concerning this credit facility for league table, tombstone and advertising purposes, and may use Obligors’ logos, trademarks or product photographs in advertising materials. As used herein, “Information”
means all information received from an Obligor or Subsidiary relating to it or its business that is identified as confidential when delivered. Any Person required to maintain the confidentiality of Information pursuant to this Section shall be
deemed to have complied if it exercises a degree of care similar to that which it accords its own confidential information. Each of Agent, Lenders and Issuing Bank acknowledges that (i) Information may include material non-public information; (ii) it has developed compliance procedures regarding the use of material non-public information; and (iii) it will handle such material non-public information in accordance with Applicable Law. 
 15.13. Certifications
Regarding Senior Notes. Obligors certify to Agent and Lenders that neither the execution nor performance of the Loan Documents or the incurrence of any Obligations by Obligors violates any provision of any Senior Notes
Document. 
 15.14. GOVERNING LAW. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, UNLESS OTHERWISE SPECIFIED,
SHALL BE GOVERNED BY THE LAWS OF THE STATE OF TEXAS, WITHOUT GIVING EFFECT TO ANY CONFLICT OF LAW PRINCIPLES (BUT GIVING EFFECT TO FEDERAL LAWS RELATING TO NATIONAL BANKS). 

15.15. Consent to Forum. EACH OBLIGOR HEREBY CONSENTS TO THE
NON-EXCLUSIVE JURISDICTION OF ANY FEDERAL OR STATE COURT SITTING IN OR WITH JURISDICTION OVER TEXAS, IN ANY PROCEEDING OR DISPUTE RELATING IN ANY WAY TO ANY LOAN DOCUMENTS, AND AGREES THAT ANY SUCH PROCEEDING
SHALL BE BROUGHT BY IT SOLELY IN ANY SUCH COURT. EACH OBLIGOR IRREVOCABLY WAIVES ALL CLAIMS, OBJECTIONS AND DEFENSES THAT IT MAY HAVE REGARDING SUCH COURT’S PERSONAL OR SUBJECT MATTER JURISDICTION, VENUE OR INCONVENIENT
FORUM. EACH PARTY HERETO IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 15.3.1. Nothing herein shall limit the right of Agent or any Lender to bring proceedings against any Obligor in any other court,
nor limit the right of any party to serve process in any other manner permitted by Applicable Law. Nothing in this Agreement shall be deemed to preclude enforcement by Agent of any judgment or order obtained in any forum or jurisdiction. 

  
 -124- 

 15.16. Waivers by Obligors. To the fullest extent permitted
by Applicable Law, each Obligor waives (a) the right to trial by jury (which Agent and each Lender hereby also waives) in any proceeding or dispute of any kind relating in any way to any Loan Documents, Obligations or Collateral;
(b) presentment, demand, protest, notice of presentment, default, non-payment, notice of intent to accelerate, notice of acceleration, maturity, release, compromise, settlement, extension or
renewal of any commercial paper, accounts, documents, instruments, chattel paper and guaranties at any time held by Agent on which an Obligor may in any way be liable, and hereby ratifies anything Agent may do in this regard;
(c) notice prior to taking possession or control of any Collateral; (d) any bond or security that might be required by a court prior to allowing Agent to exercise any rights or remedies;
(e) the benefit of all valuation, appraisement and exemption laws; (f) any claim against Agent, Issuing Bank or any Lender, on any theory of liability, for special, indirect, consequential, exemplary or punitive
damages (as opposed to direct or actual damages) in any way relating to any Enforcement Action, Obligations, Loan Documents or transactions relating thereto; and (g) notice of acceptance hereof. Each Obligor acknowledges that
the foregoing waivers are a material inducement to Agent, Issuing Bank and Lenders entering into this Agreement and that they are relying upon the foregoing in their dealings with Obligor. Each Obligor has reviewed the foregoing waivers with its
legal counsel and has knowingly and voluntarily waived its jury trial and other rights following consultation with legal counsel. In the event of litigation, this Agreement may be filed as a written consent to a trial by the court. 

15.17. Patriot Act Notice. Agent and Lenders hereby notify Obligors that pursuant to the Patriot Act, Agent and
Lenders are required to obtain, verify and record information that identifies each Obligor, including its legal name, address, tax ID number and other information that will allow Agent and Lenders to identify it in accordance with the Patriot Act.
Agent and Lenders will also require information regarding each personal guarantor, if any, and may require information regarding Obligors’ management and owners, such as legal name, address, social security number and date of birth. Borrowers
shall, promptly upon request, provide all documentation and other information as Agent, Issuing Bank or any Lender may request from time to time for purposes of complying with any “know your customer,” anti-money laundering or other
requirements of Applicable Law, including the Patriot Act and Beneficial Ownership Regulation. 
 15.18. NO ORAL
AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS BETWEEN THE PARTIES. THERE ARE
NO UNWRITTEN AGREEMENTS BETWEEN THE PARTIES. 
 15.19. Non-Applicability of Chapter
346. Obligors, Agent and Lenders hereby agree that, except for the opt-out provisions of Section 346.004 thereof, the provisions of Chapter 346 of the Texas Finance Code, as amended from
time to time (regulating certain revolving credit loans and revolving tri-party accounts) shall not apply to this Agreement or any of the other Loan Documents. 

15.20. OBLIGORS’ WAIVER OF RIGHTS UNDER TEXAS DECEPTIVE TRADE PRACTICES ACT. EACH
OBLIGOR HEREBY WAIVES ANY RIGHTS UNDER THE DECEPTIVE TRADE PRACTICES-CONSUMER PROTECTION ACT, SECTION § 17.41 ET SEQ. TEXAS BUSINESS & COMMERCE CODE, A LAW THAT GIVES CONSUMERS SPECIAL RIGHTS AND PROTECTIONS. AFTER CONSULTATION WITH AN
ATTORNEY 

  
 -125- 

 
OF THE OBLIGORS’ OWN SELECTION, EACH OBLIGOR VOLUNTARILY CONSENTS TO THIS WAIVER. EACH OBLIGOR EXPRESSLY WARRANTS AND REPRESENTS THAT EACH OBLIGOR (A) IS NOT IN A SIGNIFICANTLY
DISPARATE BARGAINING POSITION RELATIVE TO AGENT AND LENDERS, AND (B) HAS BEEN REPRESENTED BY LEGAL COUNSEL IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. 

15.21. Intercreditor Agreement. Notwithstanding anything to the contrary contained in this Agreement and each other
Loan Document, the Liens, security interests and rights granted pursuant to this Agreement or any other Loan Document shall be subject to the terms, provisions and conditions of (and the exercise of any right or remedy by the Agent hereunder or
thereunder shall be subject to the terms and conditions of), any Intercreditor Agreement in effect from time to time. In the event of any conflict between this Agreement and any other Loan Document or any Intercreditor Agreement, as the case may be,
the Intercreditor Agreement shall control, and no right, power, or remedy granted to the Agent hereunder or under any other Loan Document shall be exercised by the Agent, and no direction shall be given by the Agent, in contravention of such
Intercreditor Agreement. 
 15.22. Acknowledgement and Consent to Bail-In of Affected
Financial Institutions. Solely to the extent any Lender that is an Affected Financial Institution is a party to this Agreement and notwithstanding anything to the contrary in any Loan Document or in any other agreement, arrangement or
understanding among any such parties, each party hereto acknowledges that any liability of any Lender that is an Affected Financial Institution arising under any Loan Document, to the extent such liability is unsecured, may be subject to the
write-down and conversion powers of the applicable Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by: 

(a) the application of any Write-Down and Conversion Powers by the applicable Resolution Authority to any such liabilities arising hereunder
which may be payable to it by any Lender that is an Affected Financial Institution; and 
 (b) the effects of any Bail-In Action on any such liability, including, if applicable: 
 (i) a reduction in full or in part or
cancellation of any such liability; 
 (ii) a conversion of all, or a portion of, such liability into shares or other instruments of
ownership in such Affected Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any
rights with respect to any such liability under this Agreement or any other Loan Document; or 
 (iii) the variation of the terms of such
liability in connection with the exercise of the write-down and conversion powers of the applicable Resolution Authority. 
 15.23.
Acknowledgement Regarding Supported QFCs. To the extent that the Loan Documents provide support, through a guarantee or otherwise, for any Hedging Agreement or any other agreement or instrument that is a QFC (such support,
“QFC Credit Support”, and each such QFC, a “Supported QFC”), the parties acknowledge and agree as follows with respect to the 

  
 -126- 

 
resolution power of the Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with
the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported
QFC may in fact be stated to be governed by the laws of the State of Texas and/or of the United States or any other state of the United States): 

15.23.1. Covered Party. If a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject
to a proceeding under a U.S. Special Resolution Regime, transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property
securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regimes if the Supported QFC and such QFC Credit Support (and
any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. If a Covered Party or BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special
Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such
Default Rights could be exercised under the U.S. Special Resolution Regimes if the Supported QFC and Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood
and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support. 

15.23.2. Definitions. As used in this Section 15.23, (a) “BHC Act Affiliate” means an
“affiliate,” as defined in and interpreted in accordance with 12 U.S.C. §1841(k); (b) “Default Right” has the meaning assigned in and interpreted in accordance with 12 C.F.R. §§252.81, 47.2 or 382.1, as
applicable; and (c) “QFC” means a “qualified financial contract,” as defined in and interpreted in accordance with 12 U.S.C. §5390(c)(8)(D). 

15.24. Divisions. Any reference herein to a merger, transfer, consolidation, amalgamation, consolidation,
assignment, sale, Asset Disposition or transfer, or similar term, shall be deemed to apply to a Division Transaction (or the unwinding of such a Division Transaction), as if it were a merger, transfer, consolidation, amalgamation, consolidation,
assignment, sale, Asset Disposition or transfer, or similar term, as applicable, to, of or with a separate Person. Notwithstanding anything to the contrary in this Agreement, (i) any division of a limited liability company shall constitute a
separate Person hereunder, and each resulting division of any limited liability company that, prior to such division, is a Subsidiary, a Guarantor, an Obligor, a joint venture or any other like term shall remain a Subsidiary, a Guarantor, an
Obligor, a joint venture, or other like term, respectively, after giving effect to such division, to the extent required under this Agreement, and any resulting divisions of such Persons shall remain subject to the same restrictions and
corresponding exceptions applicable to the pre-division predecessor of such divisions, (ii) in no event shall US Concrete be permitted to effectuate a Division Transaction and (iii) if any Subsidiary
shall consummate a Division Transaction permitted under this Agreement in accordance with the foregoing, such Subsidiary shall be required, promptly after the effectiveness of such division, to comply with the requirements set forth in
Section 10.1.9 to the extent applicable. 

  
 -127- 

 15.25. Amendment and Restatement. This Agreement amends and
restates in its entirety the Initial Loan Agreement. This Agreement and the other Loan Documents govern the present relationship between the Obligors, Agent and Lenders. This Agreement, however, is in no way intended, nor shall it be construed, to
affect, replace, impair or extinguish the creation, attachment, perfection or priority of the security interests in, and other Liens on, the Collateral, which security interests and other Liens each of the Obligors, by this Agreement, acknowledges,
reaffirms and confirms to Agent and Lenders. In addition, except as otherwise provided herein, all monetary obligations and liabilities and indebtedness created or existing under, pursuant to, or as a result of, the Initial Loan Agreement, other
than Excluded Swap Obligations (the “Initial Loan Agreement Obligations”) shall continue in existence within the definition of “Obligations” under this Agreement, which obligations, liabilities and indebtedness the
Obligors, by this Agreement, acknowledge, reaffirm and confirm. The Obligors agree that any outstanding commitment or other obligation to make advances or otherwise extend credit or credit support to any Obligor pursuant to the Initial Loan
Agreement is superseded by, and renewed and consolidated under, this Agreement. The Obligors represent and warrant that none of them have assigned or otherwise transferred any rights arising under the Initial Loan Agreement. 

To the extent not amended and restated as of the Closing Date, the Loan Documents executed in connection with the Initial Loan Agreement and
in effect prior to the Closing Date (the “Existing Loan Documents”) shall continue in full force and effect, are hereby ratified, reaffirmed and confirmed in all respects, and shall, for the avoidance of doubt, constitute “Loan
Documents” under this Agreement. The terms of the Loan Documents that correspond to the Existing Loan Documents that have been amended and restated as of the Closing Date shall govern for any period occurring on or after the Closing Date, and
the terms of such Existing Loan Documents prior to their amendment and restatement shall govern for any period beginning before the Closing Date and ending on the day immediately preceding the Closing Date. In furtherance of the foregoing,
(i) each reference in any Loan Document to the “Loan Agreement”, any other Loan Document that is being amended and restated as of the Closing Date, “thereunder”, “thereof” or words of like import, is hereby
amended, mutatis mutandis, as applicable in the context, to be a reference to, and shall thereafter mean, this Agreement or such other amended and restated Loan Document, as applicable in the context (as each may be amended, modified or
supplemented and in effect from time to time) and (ii) the definition of any term defined in any Loan Document by reference to the terms defined in the “Loan Agreement” or any other Loan Document that is being amended and restated as
of the Closing Date is hereby amended to be defined by reference to the defined term in this Agreement or such other amended and restated Loan Document, as applicable (as each may be amended, modified or supplemented and in effect from time to
time). 
 In order to induce Lenders to enter into this Agreement on the Closing Date, each Obligor hereby represents, warrants and
covenants to Lenders that it has determined that each Obligor will benefit specifically and materially from the amendment and restatement of the Initial Loan Agreement pursuant to this Agreement on the Closing Date and that each Obligor requested
and bargained for the structure and terms of and security for the Loans contemplated by this Agreement on the Closing Date 
 The amount of
each Lender’s Revolver Commitment as of the Closing Date shall be as set forth on Schedule 1.1, and Agent and each Lender shall cooperate in good faith to make all payments and fundings which Agent and the Lenders must make to reallocate
the Revolver Commitments and the Obligations in respect thereof among the Lenders in accordance with their respective Revolver Commitments as set forth on Schedule 1.1. On the Closing Date, all

  
 -128- 

 
outstanding loans under the Initial Loan Agreement made by any Person that is a “Lender” under the Initial Loan Agreement immediately prior to the Closing Date who is not a Lender party
to this Agreement (each, an “Exiting Lender”) shall be repaid in full and the commitments and other obligations and rights of such Exiting Lender shall be terminated (except that such Exiting Lender shall continue to be entitled to
the benefits specified in the Initial Loan Agreement and the other Loan Documents of a Lender which assigned 100% of its interests under the Initial Loan Agreement, with respect to facts and circumstances occurring prior to the Closing Date). 

15.26. Release. EACH OBLIGOR HEREBY ACKNOWLEDGES THAT AS OF THE DATE HEREOF IT HAS NO DEFENSE, COUNTERCLAIM, OFFSET, CROSS COMPLAINT,
CLAIM OR DEMAND OF ANY KIND OR NATURE WHATSOEVER THAT CAN BE ASSERTED TO REDUCE OR ELIMINATE ALL OR ANY PART OF ITS LIABILITY TO REPAY THE “OBLIGATIONS” OR TO SEEK AFFIRMATIVE RELIEF OR DAMAGES OF ANY KIND OR NATURE FROM ANY LENDER. EACH
OBLIGOR HEREBY VOLUNTARILY AND KNOWINGLY RELEASES AND FOREVER DISCHARGES AGENT AND EACH LENDER AND THEIR RESPECTIVE PREDECESSORS, AGENTS, EMPLOYEES, SUCCESSORS AND ASSIGNS, FROM ALL POSSIBLE CLAIMS, DEMANDS, ACTIONS, CAUSES OF ACTION, DAMAGES,
COSTS, EXPENSES, AND LIABILITIES (INCLUDING ALL STRICT LIABILITIES) WHATSOEVER, KNOWN OR UNKNOWN, ANTICIPATED OR UNANTICIPATED, SUSPECTED OR UNSUSPECTED, FIXED, CONTINGENT, OR CONDITIONAL, AT LAW OR IN EQUITY, ORIGINATING IN WHOLE OR IN PART ON OR
BEFORE THE DATE OF THIS AGREEMENT, WHICH ANY OBLIGOR MAY NOW OR HEREAFTER HAVE AGAINST AGENT OR ANY LENDER OR ANY OF THEIR RESPECTIVE PREDECESSORS, AGENTS, EMPLOYEES, SUCCESSORS AND ASSIGNS, IF ANY, AND IRRESPECTIVE OF WHETHER ANY SUCH CLAIMS ARISE
OUT OF CONTRACT, TORT, VIOLATION OF LAW OR REGULATIONS, OR OTHERWISE, TO THE EXTENT ARISING FROM ANY “LOANS,” INCLUDING, WITHOUT LIMITATION, ANY CONTRACTING FOR, CHARGING, TAKING, RESERVING, COLLECTING OR RECEIVING INTEREST IN EXCESS OF
THE HIGHEST LAWFUL RATE APPLICABLE, THE EXERCISE OF ANY RIGHTS AND REMEDIES UNDER THE INITIAL LOAN AGREEMENT OR ANY OTHER LOAN DOCUMENT, AND NEGOTIATION FOR AND EXECUTION OF THIS AGREEMENT. EACH OBLIGOR WAIVES THE BENEFITS OF ANY LAW, WHICH MAY
PROVIDE IN SUBSTANCE: 
 “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN ITS
FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY IT MUST HAVE MATERIALLY AFFECTED ITS SETTLEMENT WITH THE DEBTOR.” 

EACH OBLIGOR UNDERSTANDS THAT THE FACTS WHICH IT BELIEVES TO BE TRUE AT THE TIME OF MAKING THE RELEASE PROVIDED FOR HEREIN MAY LATER TURN
OUT TO BE DIFFERENT THAN IT NOW BELIEVES, AND THAT INFORMATION WHICH IS NOT NOW KNOWN OR SUSPECTED MAY LATER BE DISCOVERED. EACH OBLIGOR ACCEPTS THIS POSSIBILITY, AND EACH OF THEM ASSUMES THE RISK OF THE FACTS TURNING OUT TO BE DIFFERENT AND NEW
INFORMATION BEING DISCOVERED; AND EACH OF THEM FURTHER AGREES THAT THE RELEASE PROVIDED FOR HEREIN SHALL IN ALL RESPECTS CONTINUE TO BE EFFECTIVE AND NOT SUBJECT TO TERMINATION OR RESCISSION BECAUSE OF ANY DIFFERENCE IN SUCH FACTS OR ANY NEW
INFORMATION.
