taking effect of any law, rule, regulation or treaty, (ii) any change in any law, rule, regulation or treaty or in the administration, interpretation or application thereof by any Governmental Authority or (iii) the making or issuance of

 “Code” shall mean the Internal Revenue Code
of 1986. 
 “FATCA” means Sections 1471 through 1474 of the Code, as of the date of this Agreement (or any amended or
successor version that is substantively comparable and not materially more onerous to comply with) and any current or future regulations or official interpretations thereof, any agreements entered into pursuant to Section 1471(b)(1) of the Code
and any intergovernmental agreements with respect thereto. 
 “L/C Commitment” shall mean the lesser of
(i) $100,000,000 and (ii) the Revolving Credit Commitment. 
 “LIBOR” shall mean, 

(i) for any interest rate calculation with respect to a LIBOR Rate Loan (other than a LIBOR Rate Loan denominated in Canadian
Dollars), the rate of interest per annum determined on the basis of the rate for deposits in the applicable Permitted Currency for a period equal to the applicable Interest Period which appears on Reuters Screen LIBOR01 Page (or other commercially
available source providing quotations of such rate as designated by the Administrative Agent from time to time) at approximately 11:00 a.m. (London time) two (2) Business Days prior to the first day of the applicable Interest Period (rounded
upward, if necessary, to the nearest 1/100th of 1%). If such rate is not available at such time for any reason, then “LIBOR” shall be determined by the Administrative Agent to be the
arithmetic average of the rate per annum at which deposits in the applicable Permitted Currency in minimum amounts of at least $5,000,000 would be offered by first class banks in the London interbank market to the Administrative Agent at
approximately 11:00 a.m. (London time) two (2) Business Days prior to the first day of the applicable Interest Period for a period equal to such Interest Period; 

(ii) for any interest rate calculation with respect to a LIBOR Rate Loan denominated in Canadian Dollars for any Interest
Period, the rate per annum determined by the Administrative Agent by reference to the average of the rates displayed on the “Reuters Screen CDOR Page” (as defined in the International Swap Dealer Association, Inc. definitions, as amended

on such screen for the purpose of displaying Canadian interbank bid rates for Canadian Dollar bankers’ acceptances) applicable to Canadian Dollar bankers’ acceptances (on a three
hundred sixty-five (365) day basis) with a term comparable to such Interest Period as of 10:00 A.M. (Eastern time) on the first day of such Interest Period (as adjusted by the Administrative Agent after 10:00 A.M. (Eastern time) to reflect
any error in a posted rate or in the posted average annual rate of interest). If, for any reason, the rates on the Reuters Screen CDOR Page are unavailable, then with respect to such LIBOR Rate Loan LIBOR means the rate of
interest determined by the Administrative Agent that is equal to the rate (rounded upwards to the nearest basis point) quoted by the Canadian Reference Bank as its discount rate for purchase of Canadian Dollar bankers’ acceptances in an
amount substantially equal to such LIBOR Rate Loan with a term comparable to such Interest Period as of 10:00 A.M. (Eastern time). No adjustment shall be made to account for the difference between the number of days in a year on which the rates
referred to in this definition are based and the number of days in a year on the basis of which interest is calculated in this Agreement; and 

(iii) for any interest rate calculation with respect to a Base Rate Loan, the rate of interest per annum determined on the
basis of the rate for deposits in Dollars in minimum amounts of at least $5,000,000 for a period equal to one month (commencing on the date of determination of such interest rate) which appears on the Reuters Screen LIBOR01 Page (or other
commercially available source providing quotations of such rate as designated by the Administrative Agent from time to time) at approximately 11:00 a.m. (London time) on such date of determination, or, if such date is not a Business Day, then the
immediately preceding Business Day (rounded upward, if necessary, to the nearest 1/100th of 1%). If such rate is not available at such time for any reason, then “LIBOR” for such Base
Rate Loan shall be determined by the Administrative Agent to be the arithmetic average of the rate per annum at which deposits in Dollars in minimum amounts of at least $5,000,000 would be offered by first class banks in the London interbank market
to the Administrative Agent at approximately 11:00 a.m. (London time) on such date of determination for a period equal to one month commencing on such date of determination. 

Each calculation by the Administrative Agent of LIBOR shall be conclusive and binding for all purposes, absent manifest error.

 “Maturity Date” shall mean the earliest to occur of (i) November 19, 2018, (ii) the date
of termination of the entire Revolving Credit Commitment by the Borrowers pursuant to Section 2.5, or (iii) the date of termination of the Revolving Credit Commitment pursuant to Section 9.2(a). 

  
 -4- 

 (e) The definition of “Consolidated EBITDA” set forth in Section 1.1 of the Credit
Agreement is hereby amended to delete the words “or group of related sales” therefrom.

extent that, pursuant to Section 4.12, amounts with respect to such Taxes were payable either to such Lender’s assignor immediately before such Lender became a party hereto or to such Lender immediately before it changed its lending
office, (c) Taxes attributable to such Recipient’s failure to comply with Section 4.12(e) and (d) any U.S. federal withholding Taxes imposed under FATCA.

(h) Section 4.10(a)(ii) of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

Applicable Law to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum payable by the applicable Credit Party shall be increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section) the Administrative Agent, the applicable Lender or the Issuing Lender, as the case may be, receives an amount equal to the sum it would have received had no such deductions been

the text, “Taxes by the U.S. Borrower” to a Governmental Authority” and (y) inserting the text “pursuant to this Section 4.12” immediately after the text, “Taxes by the U.S. Borrower to a Governmental

Status of Lenders. (i) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax
with respect to payments hereunder or under any other Loan Document shall deliver to the U.S. Borrower (with a copy to the Administrative Agent), at the time or times reasonably requested by the U.S. Borrower or the Administrative Agent, such

 -6- 

 
documentation prescribed by Applicable Law or reasonably requested by the U.S. Borrower or the Administrative Agent as will enable the U.S. Borrower or the Administrative Agent to determine

such documentation set forth in Sections 4.12(e)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material
unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender: 
 (ii) Without limiting the
generality of the foregoing, in the event that the U.S. Borrower is a “United States person” (within the meaning of Section 7701(a)(30) of the Code), 

(A) any Lender that is a U.S. Person shall deliver to the U.S. Borrower and the Administrative Agent on or prior to the date on
which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the U.S. Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from
U.S. federal backup withholding tax; 
 (B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver
to the U.S. Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the
reasonable request of the U.S. Borrower or the Administrative Agent), whichever of the following is applicable: 
 (i) in the case of a
Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, duly completed copies of IRS Form W-8BEN establishing an exemption from, or
reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or
reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

Code, (B) a “10 percent shareholder” of the U.S. Borrower within the meaning of Section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a
“U.S. Tax Compliance Certificate”) and (y) duly completed copies of IRS Form W-8BEN; or 
 (iv) to the extent a
Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit J-2 or Exhibit J-3, IRS Form
W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest
exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit J-4 on behalf of each such direct and indirect partner; 

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the U.S. Borrower and the
Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the
U.S. Borrower or the Administrative Agent), executed originals of any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in United States federal withholding Tax, duly completed, together with such
supplementary documentation as may be prescribed by Applicable Law to permit the U.S. Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and 

(D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if
such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the U.S. Borrower and the Administrative
Agent at the time or times prescribed by law and at such time or times reasonably requested by the U.S. Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of
the Code) and such additional documentation reasonably requested by the U.S. Borrower or the Administrative Agent as may be necessary for the U.S. Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine
that such Lender has complied with such 

  
 -8- 

 
Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments
made to FATCA after the date of this Agreement. 
 Each Lender agrees that if any form or certification it previously
delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the U.S. Borrower and the Administrative Agent in writing of its legal inability to do so. 

(n) Section 4.12(f) of the Credit Agreement is hereby amended by inserting the text, “(including Taxes)” after the text,
“out-of-pocket expenses”. 
 (o) Section 4.12 of the Credit Agreement is hereby amended by adding a new subsection
(h) after Section 4.12(g) as follows: 
 (h) Each Lender and the Issuing Lender shall severally indemnify the
Administrative Agent within ten (10) days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Credit Party has not already indemnified the Administrative Agent for such
Indemnified Taxes and without limiting the obligation of the Credit Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 11.9(g) relating to the maintenance of a
Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with
respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be
conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender
from any other source against any amount due to the Administrative Agent under this paragraph (h). The agreements in paragraph (h) shall survive the resignation and/or replacement of the Administrative Agent. 

(p) Sections 6.9 and 7.9 of the Credit Agreement are hereby amended by capitalizing the word, “taxes” to read, “Taxes”
wherever it appears. 
 (q) Section 11.2 of the Credit Agreement is hereby amended by adding to the end of the second to final paragraph
the following text: 
 For the avoidance of doubt, no amendment or amendment and restatement of this Credit Agreement which is in all other
respects approved by the Lenders in accordance with this Section 11.2 shall require the consent of 

  
 -9- 

 
any Lender (i) which, immediately after giving effect to such amendment or amendment and restatement, shall have no Commitment and (ii) which, substantially contemporaneously with the
effectiveness of such amendment or amendment and restatement, is paid in full all amounts owing to it hereunder. 
 (r) Section 11.9(c)
of the Credit Agreement is hereby amended by (i) inserting the text, “(and stated interest on)” after the text, “and principal amounts of” and (ii) replacing the word “may” after the text, “the Borrowers,
the Administrative Agent and the Lenders” with “shall”. 
 (s) Section 11.9 of the Credit Agreement is hereby amended by
adding a new subsection (g) after Section 11.9(f) as follows: 
 (g) Participant Register. Each Lender that
sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each
Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register
(including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such
disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be
conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the
avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register. 

(t) The Credit Agreement is amended by adding a new Exhibit J in the form of Exhibit J hereto. 

(u) Schedule 1.1(a) of the Credit Agreement is hereby amended and restated in its entirety to be in the form of Schedule 1.1(a) attached hereto
as Exhibit A. 
 (v) Schedule 1.1(b) of the Credit Agreement is hereby amended by adding a new paragraph 14 thereto as follows: 

14. All references in this Schedule to the Financial Services Authority shall (to the extent not already so provided herein) be
deemed to include any other authority which replaces all or any of the Financial Service Authority’s functions, including the Financial Conduct Authority and the Prudential Regulation Authority. 

  
 -10- 

 2. New Lenders. The parties hereto agree that, as of the Effective Date, each New Lender
shall become a “Lender” under the Credit Agreement, as amended hereby, with all the rights and duties of a “Lender” thereunder and with a Revolving Credit Commitment in the amount set forth opposite its name on Exhibit A
attached hereto. 
 3. Representations and Warranties. The U.S. Borrower hereby represents and warrants that: 

(a) The representations and warranties contained in Article VI of the Credit Agreement (other than Section 6.5(e) of

AFFIRMATION AND AMENDMENT OF GUARANTY AGREEMENTS 

Each of the undersigned acknowledges receipt of a copy of that certain Third Amendment to Credit Agreement dated as of the date hereof (the
“Amendment”) relating to the Credit Agreement dated as of May 26, 2010 (the “Credit Agreement”) referred to therein, consents to the Amendment and each of the transactions referenced therein, hereby reaffirms
its obligations under the U.S. Borrower’s Guaranty (in the case of the U.S. Borrower) and the Subsidiary Guaranty Agreement (in the case of all other signers hereof) and agrees that all references in the Guaranty Agreements to the “Credit
Agreement” shall hereafter mean and be a reference to the Credit Agreement as amended by the Amendment. Capitalized terms used herein, but not otherwise defined herein, shall have the meanings ascribed to such terms in the Credit Agreement.

 Each of the undersigned also agrees that the Subsidiary Guaranty Agreement is hereby amended as of the date hereof by adding the
following new Section 24 therein immediately following Section 23: 
 24. Excluded Swap Obligations, Etc.
(a) Notwithstanding anything herein to the contrary (including the definition of “Loan Document Obligations”), (i) the definition of “Loan Document Obligations” shall not create any guarantee by any Guarantor of
(or grant of security interest by any Guarantor to support, as applicable) any Swap Obligations which are, with respect to such Guarantor, Excluded Swap Obligations (as defined below), and (ii) any such Excluded Swap Obligations shall not
constitute Loan Document Obligations relative to such Guarantor. For purposes hereof, “Excluded Swap Obligation” means, with respect to any Guarantor, any Swap Obligation (as defined below) if, and to the extent that, all or a
portion of the guarantee of such Guarantor of, or the grant by such Guarantor of a security interest to secure, such Swap Obligation (or any guarantee thereof) is or becomes illegal under the Commodity Exchange Act (7 U.S.C. § 1 et seq.), as
amended from time to time, and any successor statute (the “Commodity Exchange Act”) or any rule, regulation or order of the Commodity Futures Trading Commission (or the application or official interpretation of any thereof) by
virtue of such Guarantor’s failure for any reason to constitute an “eligible contract participant” as defined in the Commodity Exchange Act and the regulations thereunder at the time the guarantee of such Guarantor or the grant of
such security interest becomes or would become effective with respect to such Swap Obligation. If a Swap Obligation arises under a master agreement governing more than one swap, such exclusion shall apply only to the portion of such Swap Obligation
that is attributable to swaps for which such guarantee or security interest is or becomes illegal. For purposes hereof, “Swap Obligation” means, with respect to any Guarantor, any obligation to pay or perform under any agreement,
contract or transaction that constitutes a “swap” within the meaning of section 1a(47) of the Commodity Exchange Act. 

  
 Affirmation and Amendment
of Guaranty Agreements 

 (b) Notwithstanding anything to the contrary herein or in Section 9.4 of the
Credit Agreement, amounts received from any Guarantor that is not a Qualified ECP Guarantor (as defined below) shall not be applied to any Excluded Swap Obligation of such Guarantor. For purposes hereof, “Qualified ECP Guarantor”
means, in respect of any Swap Obligation, each Guarantor that has total assets exceeding $10,000,000 at the time the relevant guarantee or grant of the relevant security interest becomes or would become effective with respect to such Swap Obligation
or such other person as constitutes an “eligible contract participant” under the Commodity Exchange Act or any regulations promulgated thereunder and can cause another person to qualify as an “eligible contract participant” at
such time by entering into a keepwell under Section 1a(18)(A)(v)(II) of the Commodity Exchange Act. 
 (c) Without
limiting the provisions of Section 18 hereof, each Qualified ECP Guarantor hereby jointly and severally absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each
other Guarantor to honor all of its obligations under this Guaranty in respect of Swap Obligations (provided, however, that each Qualified ECP Guarantor shall only be liable under this paragraph for the maximum amount of such liability that can be
hereby incurred without rendering its obligations under this paragraph or otherwise under this Guaranty voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of each
Qualified ECP Guarantor under this paragraph shall remain in full force and effect until payment in full of all Loan Document Obligations and other amounts payable under this Guaranty and until the Credit Agreement is no longer in effect. Each
Qualified ECP Guarantor intends that this paragraph constitute, and this paragraph shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Guarantor for all purposes of
Section 1a(18)(A)(v)(II) of the Commodity Exchange Act. 

  
 Affirmation and Amendment
of Guaranty Agreements 

 IN WITNESS WHEREOF, each Guarantor has caused this Affirmation and Amendment of Guaranty
Agreements to be executed and delivered as of the date hereof. 
 Dated as of November     , 2013.

integral part of the Base Indenture, as supplemented by the First Supplemental Indenture. 

 Section 1.2 Amendments. Subject to Article 2 hereof:

Indenture) Sections 8.1, 8.2, 8.3, 10.6 and 10.7; 
 (ii) the First Supplemental Indenture is hereby amended by deleting in

hereby amended by deleting in their entirety (and all references thereto contained elsewhere in the Indenture) clauses (2), (3), (4), (5), (6), (7) and (8). 

(vii) Effective as of the date hereof, none of the Issuer, the Trustee or other parties to or beneficiaries of the Indenture
shall have any rights, obligations, or liabilities under such Sections or clauses specified in (i) through (vi) above and such sections or clauses shall not be considered in determining whether an Event of Default has occurred or whether
the Issuer has observed, performed or complied with the provisions of the Indenture. 
 Section 1.3 Amendment to Definitions.
Subject to Article 2 hereof, the Base Indenture and the First Supplemental Indenture are hereby amended by deleting any definitions with respect to which references would be eliminated as a result of the amendments set forth in Section 1.2
hereof. 
 Section 1.4 Amendment of Notes. Subject to Article 2 hereof, any of the terms or provisions present in the Notes that
related to any of the provisions of the Base Indenture or the First Supplemental Indenture shall also be amended so as to be consistent with the amendments made in this Second Supplemental Indenture. 

Section 1.5 Rules of Construction. For all purposes of this Second Supplemental Indenture, except as expressly provided or unless
