In carrying out the foregoing, no payments by a Guarantor and no proceeds of Collateral of a Guarantor shall be applied to Excluded Swap Obligations of such Guarantor.

“Excluded Swap Obligation” means, with respect to any Guarantor, any Swap Obligation 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 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 not to constitute an “eligible contract participant” as defined in the Commodity Exchange Act at the time the Guarantee of such Guarantor becomes effective with respect to such related Swap Obligation.

“Guarantee” of or by any Guarantor means any obligation, contingent or otherwise, of such Guarantor guaranteeing or having the economic effect of guaranteeing any Indebtedness or other obligation of any other Person (the “primary obligor”) in any manner, whether directly or indirectly, and including any obligation of such Guarantor, direct or indirect, (a) to purchase or pay (or advance or supply funds for the purchase or payment of) such Indebtedness or other obligation or to purchase (or to advance or supply funds for the purchase of) any security for the payment thereof, (b) to purchase or lease property, securities or services for the purpose of assuring the owner of such Indebtedness or other obligation of the payment thereof, (c) to maintain working capital, equity capital or any other financial statement condition or liquidity of the primary obligor so as to enable the primary obligor to pay such Indebtedness or other obligation or (d) as an account party in respect of any letter of credit or letter of guaranty issued to support such Indebtedness or obligation; provided, that the term Guarantee shall not include endorsements for collection or deposit in the ordinary course of business.

“Qualified ECP Guarantor” means, in respect of any Swap Obligation, any of the Borrower and 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” 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.

1.5. The definition of the term “Obligations” contained in Section 5.1 of the Credit Agreement shall be amended by adding the following proviso immediately before the period appearing at the end of such defined term:

; provided, however, that, with respect to any Guarantor, the Obligations Guaranteed by such Guarantor shall exclude all Excluded Swap Obligations.

1.6. The first sentence of Section 12.1 of the Credit Agreement shall be amended by adding the following proviso immediately before the period appearing at the end of such sentence:

; provided, however, that, with respect to any Guarantor, the Obligations Guaranteed by such Guarantor shall exclude all Excluded Swap Obligations.

1.7. Section 12 of the Guaranty shall be and hereby is amended by inserting a new section immediately after Section 12.9 to read in its entirety as follows:

Section 12.10. 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 the Borrower and 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 for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section, 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 Section shall remain in full force and effect until discharged in accordance with Section 12.3. Each Qualified ECP Guarantor intends that this Section constitute, and this Section 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.

2. WAIVER.
