3 Business Days after delivery by the Borrower to the Administrative Agent of a
new Compliance Certificate pursuant to Section 6.1(c). Notwithstanding anything

continuance of any other Event of Default and, in each case, for as long as such
Event of Default shall be continuing.”

2. Section 1.1 of the Credit Agreement is hereby further amended by inserting in
the appropriate alphabetical order the following new definitions:

“Commodity Exchange Act” means the Commodity Exchange Act (7 U.S.C. § 1 et
seq.).

“Excluded Swap Obligation” means, with respect to any Guarantor, any Swap
Obligation if, and to the extent that, all or a portion of the Guaranty
Obligation of such Guarantor of, or the grant by such Guarantor of a security
interest to secure, such Swap Obligation (or any Guaranty Obligation thereof) is
or becomes illegal under 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
Guaranty Obligation of such Guarantor or the grant of such security interest
becomes 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 Guaranty Obligation or security interest is or becomes
illegal.

--------------------------------------------------------------------------------

“Fourth Amendment” means the Fourth Amendment to Credit Agreement, dated as of
March 22, 2013, among Borrower, the Guarantors party thereto, the Lenders party
thereto and Administrative Agent.

“Fourth Amendment Effective Date” means the date on which the Fourth Amendment
is effective pursuant to the terms thereof.

“Swap Obligation” means, with respect to any Guarantor, any obligation to pay or
perform under any Secured Hedging Agreement that constitutes a “swap” within the
meaning of section 1a(47) of the Commodity Exchange Act.

3. Section 2.11(d) of the Credit Agreement is hereby amended by deleting the
text “on or prior to the first anniversary of the Closing Date” appearing
therein an inserting the text “after the Fourth Amendment Effective Date and on
or prior to the sixth month anniversary of the Fourth Amendment Effective Date”
in lieu thereof.

4. In connection with the transactions contemplated by this Fourth Amendment, if
any Affected Lender holding outstanding B Term Loans, Incremental B-1 Term Loans
or Incremental B-2 Term Loans does not consent to this Fourth Amendment and does
not execute and deliver to the Administrative Agent a duly completed Assignment
and/or any other documentation necessary to reflect the replacement of such
Affected Lender by a Substitute Lender by the later of (x) the date on which the
Substitute Lender executes and delivers such Assignment and/or such other
documentation and (y) the date as of which all obligations of Borrower owing to
such Affected Lender relating to the B Term Loans, Incremental B-1 Term Loans
and Incremental B-2 Term Loans so assigned shall be paid in full by the
Substitute Lender and/or Borrower to such Affected Lender, then the Affected
Lender shall be deemed to have executed and delivered such Assignment and/or
such other documentation as of such date and Borrower shall be entitled (but not
obligated) to execute and deliver such Assignment and/or such other
documentation on behalf of such Affected Lender.

 

II.

Amendments and Modifications to the Guaranty and Security Agreement.

1. Section 1.1(c) of the Guaranty and Security Agreement is hereby amended by
adding the following definition in the appropriate alphabetical order:

“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
Guaranty Obligation or grant of the relevant security interest becomes 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.

--------------------------------------------------------------------------------

2. Section 2.1 of the Guaranty and Security Agreement shall be amended by adding
the following proviso at the end of the first sentence thereof:

“; provided that in no event shall Guaranteed Obligations be deemed to include
any Excluded Swap Obligations”.

3. Article II of the Guaranty and Security Agreement is hereby further amended
by inserting the following new Section 2.8 immediately after Section 2.7
thereof:

“Section 2.8. Keepwell. 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 Section 2.8 for the maximum amount of such liability that can
be hereby incurred without rendering its obligations under this Section 2.8, or
otherwise under this Guaranty, as it relates to such other Guarantor, 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 Section shall remain in full force and effect until the payment in
full of the Guaranteed Obligations. Each Qualified ECP Guarantor intends that
this Section 2.8 constitute, and this Section 2.8 shall be deemed to constitute,
a “keepwell, support, or other agreement” for the benefit of each other Loan
Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange
Act.”

4. Section 3.2 of the Guaranty and Security Agreement shall be amended by
inserting the following proviso at the end thereof:

“; provided that in no event shall Secured Obligations be deemed to include any
Excluded Swap Obligations”.

 

III.

Miscellaneous Provisions.

Lenders to enter into this Fourth Amendment, each Loan Party represents and
warrants to the Administrative Agent and the Lenders on and as of the Fourth
Amendment Effective Date that:

of this Fourth Amendment and the performance of the Credit Agreement and the
Guaranty and Security Agreement by each Loan Party party thereto, as amended by
this Fourth Amendment (the “Amended Loan Documents”): (i) are within each such
Loan Party’s corporate or similar powers and, at the time of execution thereof,

Requirement of Law, (C) conflict with, contravene, constitute a default or
breach under, any material Contractual Obligation of any Loan Party or any of
their respective Subsidiaries other than those which could not reasonably be
expected to have, either

individually or in the aggregate, a Material Adverse Effect, or (D) result in
the imposition of any Lien (other than a Permitted Lien) upon any property of
any Loan Party or any of their respective Subsidiaries and (iii) do not require
any Loan Party or any of their respective Subsidiaries to obtain any Permit
from, or make any filing with, any Governmental Authority or obtain any consent
from, or notice to, any Person, other than as has been obtained and made on or
prior to the Fourth Amendment Effective Date and which remains in full force and
effect on the Fourth Amendment Effective Date except where the failure to obtain
any such Permit, make any such filing or obtain any such consent could not
reasonably be expected to have, either individually or in the aggregate, a
Material Adverse Effect.

(b) This Fourth Amendment has been duly executed and delivered by or on behalf
of such Loan Party.

(c) Each of this Fourth Amendment and each Amended Loan Document is the legal,
valid and binding obligation of such Loan Party to the extent a party thereto

as may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer or other similar laws affecting creditors’
rights generally or by general equitable principles relating to enforceability.

(d) No Default or Event of Default has occurred and is continuing on the Fourth
Amendment Effective Date or would occur after giving effect to this Fourth
Amendment.

(e) No action, claim or proceeding is now pending or, to the knowledge of any
Loan Party, threatened against such Loan Party, at law, in equity or otherwise,
before any court, board, commission, agency or instrumentality of any foreign,
federal, state, or local government or of any agency or subdivision thereof, or
before any arbitrator or panel of arbitrators, which (i) challenges any Loan
Party’s right or power to enter into or perform any of its obligations under
this Fourth Amendment, the Amended Loan Documents, or any other Loan Document to
which it is or will be, a party, or the validity or enforceability of this
Fourth Amendment, the Amended Loan Documents or any other Loan Document or any
action taken thereunder, or (ii) has a reasonable risk of being determined
adversely to such Loan Party and that, if so determined, could reasonably be
expected to have a Material Adverse Effect.

Credit Agreement and the other Loan Documents shall be unmodified and shall
continue to be in full force and effect in accordance with their terms, and
(b) this Fourth Amendment shall not be deemed a waiver or modification of any
other term or condition of any Loan Document and shall not be deemed to
prejudice any right or rights which Administrative Agent or any Lender may now
have or may have in the future under or in connection with any Loan Document or
any of the instruments or agreements referred to therein, as the same may be
amended from time to time.

Fourth Amendment.
