Loans (other than pursuant to Section 2.06(c)(i) (solely to the extent such prepayment is made on account of one or more Designated Asset Dispositions permitted pursuant to Section 6.04(h) and does not result in the aggregate
principal amount of the Tranche B Loans outstanding after giving effect to such prepayment to be less than $88,000,000), Section 2.06(c)(iv) or, for the avoidance of doubt, Section 2.05(a) or 2.05(b)) or
(ii) effect any Repricing Amendment (including, for the avoidance of doubt, pursuant to Section 2.18), and, in each case, no Event of Default shall have occurred and be continuing immediately after giving effect to such prepayment,

Section 2.06(c)(i) solely to the extent such prepayment is made on account of one or more Designated Asset Dispositions permitted by Section 6.04(h), and, in each case, such prepayment does not result in the aggregate
principal amount of Tranche B Loans outstanding after giving effect to such prepayment to be less than $88,000,000 and does not occur at time when an Event of Default shall have occurred and be continuing immediately after giving effect to such
prepayment, the Borrower shall pay to the Administrative Agent, for the ratable account of each Lender, a prepayment premium equal to 2.00% of the aggregate principal amount of the Tranche B Loans so prepaid (such premium, the “Asset Sale
Prepayment Premium”). 
 (iii) Without limiting the generality of the foregoing and notwithstanding anything to the
contrary in this Agreement or any other Loan Document, it is understood and agreed that if (x) an Event of Default shall have occurred and be continuing immediately after giving effect to any prepayment of Tranche B Loans, whether in whole or
in part, made after the Second Amendment Effective Date or (y) the Tranche B Loans are accelerated (including, without limitation, as the result of the occurrence of any Event of Default or the commencement of any Insolvency Proceeding, whether
pursuant to Section 7.02 or 7.03, by operation of law or otherwise), a fee equal to the Makewhole Amount plus the Repayment Fee Percentage, in each case, with respect to the aggregate principal amount of the Tranche B Loans
subject to such prepayment (determined in the case of acceleration, as of the date of acceleration as if the aggregate principal amount of Tranche B Loans then outstanding were voluntarily prepaid on such date under Section 2.06(b) (but,
in the case of any portion of such fee attributable to the definition of “Makewhole Amount”, determined disregarding any interest payments hereunder that are actually made by the Borrower after such date of acceleration), will also be due
and payable and, in the case of acceleration, will be treated and deemed as though the Tranche B Loans were voluntary prepaid as of such date under Section 2.06(b) and shall constitute part of the Obligations for all purposes hereof (the
prepayment fee payable under this clause (f)(iii), the “Default Prepayment Premium”), it being understood and agreed that the Default Prepayment Premium shall be without duplication of any amounts payable under clause (f)(i) or
(f)(ii) above. The Default Prepayment Premium payable in accordance with the immediately preceding sentence shall be presumed to be the liquidated damages sustained by each Lender as a result of the early termination, and the Loan Parties agree that
it is reasonable under the circumstances currently existing, and will be payable notwithstanding the satisfaction, release, payment, restructuring, reorganization, replacement, reinstatement, defeasance or compromise of any of the Tranche B Loans in
any Insolvency Proceeding, any foreclosure (whether by power of judicial proceeding or otherwise) or deed in lieu of foreclosure or the making of a distribution of any kind in any Insolvency Proceeding. THE LOAN PARTIES EXPRESSLY WAIVE THE
PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE DEFAULT PREPAYMENT PREMIUM IN CONNECTION WITH ANY SUCH

ACCELERATION. The Loan Parties expressly agree that (A) the Default Prepayment Premium is reasonable and is the product of an arm’s length transaction between sophisticated business

Parties giving specific consideration in this transaction and the transactions contemplated by the Second Amendment for such agreement to pay the Default Prepayment Premium, and (D) the Loan Parties shall be estopped hereafter from claiming
differently than as agreed to in this Section 2.06(f)(iii).

Documents. 
 (b) Enforceability. This Second Amendment has been duly executed and delivered by each Loan Party. This Second
Amendment constitutes a legal, valid and binding obligation of each Loan Party, enforceable against such Loan Party in accordance with its terms, except as such enforceability may be limited by any applicable bankruptcy, insolvency, reorganization,
fraudulent conveyance, moratorium or similar law affecting creditors’ rights generally or general principles of equity. 
 (c)
Representations and Warranties. After giving effect to this Second Amendment, the representations and warranties contained in each Loan Document are true and correct in all material respects (except that such materiality qualifier shall be
not applicable to any representations and warranties that already are qualified or modified by the materiality in the text thereof) on and as of the date hereof, as though made on and as of the date hereof (except to the extent that such
representations and warranties relate solely to an earlier date, in which case, such representations and warranties shall be true and correct in all material respects (except that such materiality qualifier shall not be applicable to any
representations and warranties that already are qualified or modified by materiality in the text thereof) as of such earlier date). 
 (d)
No Default. No Default or Event of Default has occurred and is continuing as of the date hereof. 
 SECTION 8. Reaffirmation and
Ratification. The Loan Parties hereby: 
 (a) acknowledge and agree that the Liens and security interests created under the Security
Agreement and the other Security Documents in favor of the Administrative Agent for the benefit of the Lenders and securing payment of all “Obligations” (including, without limitation, all prior loans or advances made to the Borrower by
the Lenders) outstanding pursuant to the Credit Agreement shall remain in full force and effect with respect to the Obligations and are hereby and thereby reaffirmed, 

  
 13 








 (b) acknowledge and reaffirm their respective obligations as set forth in each Loan Document (as
amended or otherwise modified by this Second Amendment), including, without limitations, all Obligations under the Credit Agreement and the other Loan Documents (as amended or otherwise modified by this Second Amendment), 

(c) agree to continue to comply with, and be subject to, all of the terms, provisions, conditions, covenants, agreements and obligations
applicable to them set forth in each Loan Document (as amended or otherwise modified by this Second Amendment), which remain in full force and effect, and 

(d) confirm, ratify and reaffirm that (i) the guarantees and indemnities given by them pursuant to the Credit Agreement and/or any other
Loan Documents continue in full force and effect, following and notwithstanding the amendments thereto pursuant to this Second Amendment, and (ii) the security interest granted to Administrative Agent, for the benefit of the Lenders, pursuant
to the Loan Documents in all of their right, title, and interest in all then existing and thereafter acquired or arising Collateral in order to secure prompt payment and performance of the Obligations, is continuing and is and shall remain
unimpaired and continue to constitute a first priority security interest (subject to Permitted Liens) in favor of the Administrative Agent, for the benefit of the Lenders, with the same force, effect and priority in effect immediately prior to
entering into this Second Amendment. 
 SECTION 9. Release. Each Loan Party hereby remises, releases, acquits, satisfies and forever
discharges the Arranger, the Administrative Agent, the Lenders and their respective agents, employees, officers, directors, predecessors, attorneys and all others acting or purporting to act on behalf of or at the direction of the Arranger, the
Administrative Agent or the Lenders (“Releasees”), of and from any and all manner of actions, causes of action, suits, damages, claims and demands, in each case, that as of the date hereof are known or reasonably should be known to
such Loan Party, in law or in equity, which such Loan Party ever had, now has or, to the extent arising from or in connection with any act, omission or state of facts taken or existing on or prior to the date hereof, may have after the date hereof
against the Releasees, for, upon or by reason of any matter, cause or thing whatsoever through the date hereof (it being understood that nothing in this sentence shall release or otherwise affect the covenants of the Releasees under the Credit
Agreement and the other Loan Documents, in each case, after the Second Amendment Effective Date). Without limiting the generality of the foregoing, each Loan Party hereby waives and affirmatively agrees not to allege or otherwise pursue any actions,
causes of action, suits, damages, claims and demands that it shall or may have as of the date hereof against any Releasees in connection with the Credit Agreement or the other Loan Documents, including, but not limited to, the rights to contest
(a) the right of the Arranger, the Administrative Agent and each Lender to exercise its rights and remedies described in the Credit Agreement, (b) any provision of the Credit Agreement or the other Loan Documents or (c) any conduct of
the Arranger, the Administrative Agent, the Lenders or other Releasees relating to or arising out of the Credit Agreement or the other Loan Documents on or prior to the date hereof. 

  
 14 








 SECTION 10. Estoppel. To induce the Arranger, the Administrative Agent and the Lenders to
enter into this Second Amendment, each Loan Party hereby acknowledges and agrees that, after giving effect to this Second Amendment, as of the date hereof, to the knowledge of any Loan Party, there exists no right of offset, defense, counterclaim or
objection in favor of any Loan Party as against the Arranger, the Administrative Agent or any Lender with respect to the Obligations. 

SECTION 11. Effects on Loan Documents. Except as specifically amended herein or pursuant hereto, all provisions of the Credit Agreement
and the other Loan Documents shall continue to be in full force and effect and are hereby in all respects ratified and confirmed. Except as otherwise expressly provided herein, the execution, delivery and effectiveness of this Second Amendment shall
not operate as a waiver of any right, power or remedy of any Lender, the Arranger or the Administrative Agent under any of the Loan Documents or constitute a waiver or consent of any provision of the Loan Documents or to any further or future action
on the part of the Loan Parties that would require a waiver or consent of the Majority Lenders or the Administrative Agent. 
 SECTION 12.
GOVERNING LAW; WAIVER OF JURY TRIAL. THIS SECOND AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK. EACH PARTY HERETO HEREBY AGREES AS
SET FORTH FURTHER IN SECTION 10.13 OF THE CREDIT AGREEMENT AS IF SUCH SECTION WAS SET FORTH IN FULL HEREIN, MUTATIS MUTANDIS. 

SECTION 13. Loan Document. This Second Amendment shall constitute a “Loan Document” for all purposes of the Credit Agreement
and the other Loan Documents. From and after the Second Amendment Effective Date, the terms “Agreement”, “this Agreement”, “herein”, “hereafter”, “hereto”, “hereof” and words of similar
import, as used in the Credit Agreement and the other Loan Documents, shall refer to the Credit Agreement as amended hereby. 
 SECTION 14.
Execution in Counterparts. This Second Amendment may be executed in counterparts (and by different parties hereto in different counterparts), including by means of facsimile or electronic transmission, each of which when so executed and
delivered shall be an original, but all of which shall together constitute one and the same instrument.

 EXHIBIT A 

FIRST AMENDMENT dated as of September 28, 2015 (this “Agreement”), to the Intercreditor Agreement dated
as of August 7, 2013 (as modified by the Notice of Refinancing and Reaffirmation of Intercreditor Agreement dated as of December 15, 2014, the “Intercreditor Agreement”), among Bank of America, N.A., as Agent for the ABL
Secured Parties (in such capacity, the “ABL Representative”), JPMorgan Chase Bank, as Administrative Agent for the Term Loan Secured Parties (in such capacity, the “Term Loan Representative”), and the Grantors party
thereto. 
 WHEREAS, pursuant to the Fourth Amendment to Loan, Security and Guaranty Agreement dated as of the date hereof (the “ABL
Fourth Amendment”), (a) the Existing ABL Agreement has been modified to, among other things, include Eligible Pledged Cash (as defined in the Existing ABL Agreement) in the Canadian Borrowing Base and the U.S. Borrowing Base (in each
case, as defined in the Existing ABL Agreement) and (b) the Lenders under the Existing ABL Agreement have authorized the ABL Representative to enter into this Agreement. 

WHEREAS, pursuant to the Second Amendment dated as of the date hereof to the Term Loan Agreement (the “Term Second
Amendment”), the Lenders under the Term Loan Agreement have authorized the Term Loan Representative to enter into this Agreement. 

WHEREAS, the ABL Representative, the Term Loan Representative and the Grantors desire to amend the Intercreditor Agreement as set forth below.

 NOW THEREFORE, in consideration of the mutual agreements herein contained and other good and valuable consideration, the sufficiency and
receipt of which are hereby acknowledged, the parties hereto agree as follows: 
 SECTION 1. Defined Terms. Capitalized terms used
but not defined herein (including the recitals hereto) shall have the meanings assigned to them in the Intercreditor Agreement. 
 SECTION
2. Amendments to the Intercreditor Agreement. 
 (a) Section 1.2 of the Intercreditor Agreement is hereby amended as follows:

 (i) Clauses (f) and (g) of the definition of “ABL Facility First Priority Collateral” are hereby
amended and restated in their entirety as follows: 
 “(f) (i) all Deposit Accounts constituting Eligible Pledged
Cash Accounts (including all cash, cash equivalents, financial assets, negotiable instruments and other evidence of payment, and other funds on deposit therein or credited thereto), provided that the aggregate amount of the cash, cash
equivalents, financial assets, negotiable instruments and other evidences of payment, Investment Property and other funds or other property on deposit or held in or credited to all the Eligible Pledged Cash Accounts does not exceed at any one time
the sum of (A) $43,000,000 (it being agreed that the provisions of Section 4.1(d) shall not apply to this clause (A)), (B) the Proceeds of the ABL Facility First Priority Collateral received by the Grantors and (C) interest and
other profits thereon, and (ii) all other Deposit Accounts (other than Deposit Accounts that contain only the Proceeds of the Term Loan Priority Collateral) with any bank or other financial institution (including all cash, cash equivalents,
financial assets, negotiable instruments and other 







 
evidence of payment, and other funds on deposit therein or credited thereto, other than, in each case, to the extent constituting the identifiable Proceeds of Term Loan Priority
Collateral);” 
 “(g) (i) all Securities Accounts constituting Eligible Pledged Cash Accounts (including all
Investment Property and all funds or other property held therein or credited thereto), provided that the aggregate amount of the cash, cash equivalents, financial assets, negotiable instruments and other evidences of payment, Investment
Property and other funds or other property on deposit or held in or credited to all the Eligible Pledged Cash Accounts does not exceed at any one time the sum of (A) $43,000,000 (it being agreed that the provisions of Section 4.1(d) shall
not apply to this clause (A)), (B) the Proceeds of the ABL Facility First Priority Collateral received by the Grantors and (C) interest and other profits thereon, and (ii) all other Securities Accounts (other than Securities Accounts
that contain only the Proceeds of the Term Loan Priority Collateral) with any securities intermediary (including any and all Investment Property and all funds or other property held therein or credited thereto, other than, in each case, to the
extent constituting the identifiable Proceeds of Term Loan Priority Collateral);” 

        (ii) Clauses (a) and (j) of the definition of “Term Loan
Priority Collateral” is hereby amended and restated in their entirety as follows: 
 “(a) Deposit Accounts,
Securities Accounts and Commodity Accounts that contain only proceeds of items (b) through (k) below, other than any Eligible Pledged Cash Accounts expressly constituting ABL Facility First Priority Collateral pursuant to clause
(f) or (g) of the definition of such term;” 
 “(j) to the extent not otherwise included, all Proceeds
(including, without limitation, all insurance proceeds relating to the above and any identifiable proceeds of items (a) through (k) of this definition contained in any Deposit Accounts, Securities Accounts and Commodity Accounts that
otherwise constitute Term Loan Priority Collateral), Supporting Obligations and products of any and all of the foregoing and all collateral security and guarantees given by any Person with respect to any of the foregoing; and” 

        (iii) The following definitions are hereby added in the appropriate
alphabetical order: 
 “Eligible Pledged Cash Account” means each Deposit Account or Securities Account
established by any Grantor at Bank of America or one of its Affiliates, or any other bank or other financial institution, provided that the cash, cash equivalents, Investment Property or other funds on deposit or held therein or credited
thereto constitute a component of the “borrowing base” (however denominated) under the ABL Agreement. 
 (b) Section 9.5(a)
of the Intercreditor Agreement is hereby amended and restated in its entirety as follows: 
 “(a) No amendment or
modification of any of the provisions of this Agreement shall be effective unless the same shall be in writing and signed by the ABL Representative and the Term Loan Representative. Each Grantor agrees that this Agreement may be amended or modified
by the ABL Representative and the Term Loan Representative without notice to, or the consent of, any Grantor, provided that (i) no amendment or modification (A) to decrease the ABL Cap Amount or expand the types of Capped ABL
Obligations, or to decrease of the Term Cap Amount or expand the types of Capped Term Obligations or (B) to the definition of Eligible Pledged Cash Account (or any provision of the definitions of ABL Facility First Priority








 
Collateral or Term Loan Priority Collateral relating to Eligible Pledged Cash Accounts) may, in either case, be made without the prior written consent of the Parent and (ii) no Grantor shall
be bound by any such amendment or modification that directly and adversely affects the rights or duties of such Grantor in any material respect.” 

SECTION 3 Effect of this Agreement. (c) Except as expressly set forth herein, this Agreement shall not by implication or otherwise
limit, impair, constitute a waiver of, or otherwise affect the rights and remedies of the ABL Representative or the Term Loan Representative under the Intercreditor Agreement or any of the ABL Documents or the Term Loan Documents, and shall not
alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Intercreditor Agreement or any of the ABL Documents or the Term Loan Documents, all of which are ratified and affirmed in
all respects and shall continue in full force and effect. Nothing herein shall be deemed to entitle any party to the Intercreditor Agreement to a consent to, or a waiver, amendment, modification or other change of, any of the terms, conditions,
obligations, covenants or agreements contained in the Intercreditor Agreement in similar or different circumstances. 
 (b) On and after the
date hereof, each reference in the Intercreditor Agreement to “this Agreement”, “hereunder”, “hereof”, “herein” or words of like import, and each reference to the Intercreditor Agreement in any ABL Document or
any Term Loan Document, shall be deemed to be a reference to the Intercreditor Agreement as amended hereby. 
 SECTION 4.
Counterparts. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.
Delivery of an executed counterpart of a signature page of this Agreement by facsimile transmission or other electronic imaging shall be as effective as delivery of a manually executed counterpart of this Agreement. 

SECTION 5. Governing Law. This Agreement shall be construed in accordance with and governed by the law of the State of New York, except
as otherwise required by mandatory provisions of law and except to the extent that remedies provided by the laws of any jurisdiction other than the State of New York are governed by the laws of such jurisdiction. 

SECTION 6. Heading. Section headings used herein are for convenience of reference only, are not part of this Agreement and shall not
affect the construction of, or be taken into consideration in interpreting, this Agreement. 
 SECTION 7. Incorporation by Reference.
The provisions of Sections 9.8 and 9.10 of the Intercreditor Agreement are hereby incorporated by reference, mutatis mutandis, as if set forth in full herein.
