Guarantor as specified in any agreement between the relevant Loan Parties and hedge counterparty applicable to such Swap Obligations, and agreed by the Administrative Agent. 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. 

  
 11 

 ‘Obligations’ shall mean, collectively, all Indebtedness,
liabilities and obligations (other than Excluded Swap Obligations) of the Borrower and each Guarantor to the Administrative Agent, the Issuing Bank, the Lenders and each Affiliate of a Lender party to a Permitted Hedging Agreement (including any
Permitted Hedging Agreements between such Persons in existence prior to the date hereof) and each Treasury Management Counterparty, of whatsoever nature and howsoever evidenced, due or to become due, now existing or hereafter arising, whether direct
or indirect, absolute or contingent, which may arise under, out of, or in connection with the Credit Agreement, the other Loan Documents, each Permitted Hedging Agreement (to the extent that the Obligations arise under, out of, or in connection with
such Permitted Hedging Agreement before or during such time as the Lender party to such Permitted Hedging Agreement is a party to the Credit Agreement, or in the case of an Affiliate of a Lender party to such Permitted Hedging Agreement, the Lender
affiliated with such Affiliate, is a party to the Credit Agreement) and all other agreements, guarantees, notes and other documents entered into by any party in connection therewith, and any amendment, restatement or modification of any of the
foregoing, including, but not limited to, (other than Excluded Swap Obligations) the full and punctual payment when due of any unpaid principal of the Loans and LC Exposure, any amounts payable in respect of an early termination under any Permitted
Hedging Agreement, interest (including, without limitation, interest accruing at any post-default rate and interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding,
whether or not a claim for post-filing or post-petition interest is allowed in such proceeding), fees, reimbursement obligations, guaranty obligations, penalties, indemnities, legal and other fees, charges and expenses, and amounts advanced by and
expenses incurred in order to preserve any collateral or security interest, whether due after acceleration or otherwise. 

‘Qualified ECP Guarantor’ shall mean, 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 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. 
 ‘Swap Obligation’ shall 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.” 

3.2 Amendment to Article II. Article II of the Guaranty Agreement is hereby amended by adding the following Section 2.03 thereto:

 “Section 2.03 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 

  
 12 

 
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 2.03 for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section 2.03, or otherwise under this Agreement, 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 such Guarantor is released from its obligations hereunder in accordance with
Section 10.15 hereof. Each Qualified ECP Guarantor intends that this Section 2.03 constitute, and this Section 2.03 shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of the Borrower and
each other Guarantor for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.” 
 Section 4.
Waiver. The Borrower has informed the Administrative Agent that it exceeded the amount set forth in Section 9.08 with regard to lease payments for fiscal years 2012 and 2013, and the Borrower has requested that the Majority Lenders

or alter any provision of the Credit Agreement, the other Loan Documents, or any other contract or instrument, or (iii) constitute any course of dealing or other basis for altering any obligation of the Borrower or any right, privilege or
remedy of the Administrative Agent or the Lenders under the Credit Agreement, the other Loan Documents, or any other contract or instrument. Nothing in this Omnibus Amendment shall be construed to be a consent by the Administrative Agent or the
Lenders to any Other Violations.
