NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration (the receipt and sufficiency of which is hereby acknowledged), the parties hereto hereby agree as follows:

AGREEMENT

1. Incorporation of Recitals. The Recitals hereto are incorporated herein by reference to the same extent and with the same force and effect as if fully set forth herein. Capitalized terms defined in the Loan Agreement shall have the same defined meanings when such terms are used herein.

2. Amendments to Loan Agreement. The Loan Agreement is hereby amended as follows:

(a) The following definitions are hereby added to Section 1 of the Loan Agreement in the proper alphabetical order, to read in their respective entireties as follows:

“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 a Borrower, any Swap Obligation if, and to the extent that, all or a portion of the Guarantee of such Borrower, or the grant by such Borrower 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 Borrower’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 Obligations of such Borrower are incurred or the Guarantee of such Borrower 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 Obligations, Guarantee or security interest is or becomes illegal.

“Qualified ECP Borrower” means, in respect of any Swap Obligation, each Borrower that has total assets exceeding $10,000,000 at the time the relevant Obligations, 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 Borrower, 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.

(b) The parties agree that, notwithstanding any provision to the contrary contained in the Loan Agreement or the other Loan Documents, the Obligations (as defined in the Loan Agreement), shall not include Excluded Swap Obligations. Each Qualified ECP Borrower 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 Borrower to honor

2

all of its obligations under the Loan Documents in respect of Swap Obligations (provided, however, that each Qualified ECP Borrower shall only be liable under this clause (b) for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this clause (b) or otherwise under the Loan Agreement, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of each Qualified ECP Borrower under this Section shall remain in full force and effect until termination of the Obligations pursuant to the terms of the Loan Agreement. Each Qualified ECP Borrower intends that this clause (b) constitute, and this clause (b) shall be deemed to constitute, a “keepwell, support or other agreement” for the benefit of each other Borrower for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

(c) The form of Exhibit A referenced in the definition of “Covenant Compliance Certificate” contained in Section 1 of the Loan Agreement and attached to the Loan Agreement is amended to read as set forth in Annex 1 attached hereto and made a part hereof and part of the Loan Agreement as Exhibit A.

(d) Clause (i) of the definition of “Index Rate” set forth in Section 1 of the Loan Agreement is amended to read in its entirety as follows:

(London, England time) two (2) Business Days prior to the Index Rate Determination Date; provided, that if no such offered rate appears on such page, the rate used for such period will be the per annum rate of interest determined by the Administrative Agent to be the rate at which U.S. dollar deposits for such period, are offered to the Administrative Agent in the London Inter-Bank Market as of 11:00 A.M. (London, England time), on the day that is two (2) Business Days prior to the Index Rate Determination Date, divided by

(e) The definition of “Index Rate” set forth in Section 1 of the Loan Agreement is amended to add the following as the final sentence thereof:

If at any time the Index Rate is less than zero, the Index Rate shall be deemed to be zero for purposes of this Agreement.

(f) The second sentence of the definition of “LIBOR” set forth in Section 1 of the Loan Agreement is amended to read in its entirety as follows:

For purposes hereof, the term “Fixed LIBOR” shall mean, for any Interest Period with respect to any LIBOR Loan, the rate per

3

annum (rounded upwards, if necessary, to the nearest 1/100 of 1%) appearing on that page of Reuters reporting service, or such similar service as determined by the Administrative Agent, that displays ICE (or any successor thereto if ICE is no longer making a London Interbank Offered Rate available) interest settlement rates for deposits in U.S. Dollars as the London interbank offered rate for deposits in Dollars at approximately 11:00 a.m. (London time) two Business Days prior to the first day of such Interest Period for a term comparable to such Interest Period; provided that if for any reason such rate is not available, Fixed LIBOR shall be, for any Interest Period, the rate per annum reasonably determined by the Administrative Agent as the rate of interest at which Dollar deposits in the approximate amount of the LIBOR Loan comprising part of such borrowing would be offered by the Administrative Agent to major banks in the London interbank Eurodollar market at their request at or about 10:00 a.m. two Business Days prior to the first day of such Interest Period for a term comparable to such Interest Period. If at any time Fixed LIBOR is less than zero, Fixed LIBOR shall be deemed to be zero for purposes of this Agreement.

(g) The definitions of “Minimum Tangible Net Worth Compliance Level” and “Tangible Net Worth” contained in Section 1 of the Loan Agreement and the usages thereof in the Loan Agreement are hereby deleted.

(h) Section 7.1 of the Loan Agreement is amended to read in its entirety as follows:

(j) Each of the Borrowers, the Administrative Agent and each Lender agrees that, after the Amendment Effective Date (as hereinafter defined), each reference in the Loan Documents to the Loan Agreement shall be deemed to be a reference to the Loan Agreement as amended hereby.

3. No Implied Waivers. Each of the Borrowers acknowledges and agrees that this Amendment shall not constitute a waiver, express or implied, of any Default, Event of Default, covenant, term or provision of the Loan Agreement or any other Loan Document, nor shall it create any obligation, express or implied, on the part of the Administrative Agent or any Lender to waive, or to consent to any amendment of, any existing or future Default, Event of Default or violation of any covenant, term or provision of any Loan Document. The Administrative Agent and the Lenders shall be entitled to require strict compliance by the Borrowers with the Loan Documents, and nothing herein shall be deemed to establish a course of action or a course of dealing with respect to requests by the Company or any Borrower for waivers or amendments of any Default, Event of Default, covenant, term or provision of any Loan Document.
