“Commodity Exchange Act” means the Commodity Exchange Act (7

U.S.C. § 1 et seq.), as amended from time to time, and any successor statute.

“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 of such Guarantor of, or the grant by such Guarantor of a security interest to secure, such Swap Obligation (or any Guaranty 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) (a) 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 of such Guarantor or the grant of such security interest becomes or would become effective with respect to such Swap Obligation or (b) in the case of a Swap Obligation subject to a clearing requirement pursuant to Section 2(h) of the Commodity Exchange Act (or any successor provision thereto), because such Guarantor is a “financial entity,” as defined in Section 2(h)(7)(C)(i) the Commodity Exchange Act (or any successor provision thereto), at the time the Guaranty of such Subsidiary Guarantor

becomes or would become effective with respect to such related Swap Obligation.

SECTION 5. Governing Law. THIS AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS (AS OPPOSED TO CONFLICTS OF LAWS PROVISIONS) OF THE STATE OF ILLINOIS.

SECTION 7. Counterparts. This Amendment may be executed in any number of counterparts, each of which when so executed shall be deemed an original, but all such counterparts shall constitute one and the same instrument.

“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 2.1 for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section 2.1 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 2.1 shall remain in full force and effect until all the Guaranteed Obligations are paid in full and the Commitments are terminated. Each Qualified ECP Guarantor intends that this Section 2.1 constitute, and this Section 2.1 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.”

SECTION 10. Post-Closing Covenant. Within 60 days after the date hereof (or such later date as the Agent may agree in its sole discretion), the Borrower will take any actions deemed reasonably advisable by the Agent due to this Amendment to preserve or continue the perfection of liens and security interests granted prior to the date hereof securing the Obligations, including without limitation any amendments to real property mortgages, date down or modification endorsements to the title policies insuring such mortgages (to the extent available in the

applicable jurisdictions at commercially reasonable rates) and/or title searches and opinions of counsel with respect thereto.

If said

mortgaged property is not sold by December 31, 2013, then the Borrowers shall have sixty (60)

days to comply with the requirements set forth in this Section 9.
