Agreement in the appropriate alphabetical order to read as follows:

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

Obligation if, and to the extent that, all or a portion of the Guaranty of such
Loan Party of such Swap Obligation (or any Guarantee thereof) is or becomes
illegal under the Commodity Exchange Act (or the application or official
interpretation thereof) by virtue of such Loan Party’s failure for any reason to
constitute an “eligible contract participant” as defined in the Commodity
Exchange Act (determined after giving effect to Section 4.08 and any and all
guarantees of such Loan Party’s Swap Obligations by other Loan Parties) at the
time the Guaranty of such Loan Party becomes effective with respect to such Swap
Obligation. If a Swap Obligation arises under a Master Agreement governing more

administratively feasible for the Administrative Agent, such other day as
otherwise reasonably determined by the Administrative Agent).

“Specified Loan Party” has the meaning specified in Section 4.08.

(b) Section 1.06. Subsections (a) and (c) of Section 1.06 of the Credit
Agreement are hereby amended to read as follows:

(a) The Company may from time to time request that Revolving Loans be made
and/or Letters of Credit be issued in a currency other than those specifically
listed in the definition of “Alternative Currency”; provided that (i) such
requested currency is a lawful currency (other than Dollars) that is readily
available and freely transferable and convertible into Dollars and (ii) such
requested currency shall only be a LIBOR Quoted

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

Currency to the extent that there is published LIBOR rate for such currency. In
the case of any such request with respect to the making of Revolving Loans, such
request shall be subject to the approval of the Administrative Agent and the
Lenders that would be obligated to make Credit Extensions denominated in such
requested currency; and in the case of any such request with respect to the
issuance of Letters of Credit, such request shall be subject to the approval of
the Administrative Agent and the L/C Issuer.

*******

(c) Any failure by a Lender or the L/C Issuer, as the case may be, to respond to
such request within the time period specified in the preceding sentence shall be
deemed to be a refusal by such Lender or the L/C Issuer, as the case may be, to
permit Revolving Loans to be made or Letters of Credit to be issued in such
requested currency. If the Administrative Agent and all the Lenders that would
be obligated to make Credit Extensions denominated in such requested currency
consent to making Revolving Loans in such requested currency and the
Administrative Agent and such Lenders reasonably determine that a Eurocurrency
Base Rate is available to be used for such requested currency, the
Administrative Agent shall so notify the Company and (i) the Administrative
Agent and such Lenders may amend the definition of Eurocurrency Base Rate for
any Non-LIBOR Quoted Currency to the extent necessary to add the applicable
Eurocurrency Base Rate for such currency and (ii) to the extent the definition
of Eurocurrency Base Rate reflects the appropriate interest rate for such
currency or has been amended to reflect the appropriate rate for such currency,
such currency shall thereupon be deemed for all purposes to be a LIBOR Quoted
Currency or a Non-LIBOR Quoted Currency, as applicable, for purposes of any
Borrowings of Revolving Loans; and if the Administrative Agent and the L/C
Issuer consent to the issuance of Letters of Credit in such requested currency,
the Administrative Agent shall so notify the Company and (A) the Administrative
Agent and the L/C Issuer may amend the definition of Eurocurrency Base Rate for
any Non-LIBOR Quoted Currency to the extent necessary to add the applicable
Eurocurrency Base Rate for such currency and (B) to the extent the definition of
Eurocurrency Base Rate reflects the appropriate interest rate for such currency
or has been amended to reflect the appropriate rate for such currency, such
currency shall thereupon be deemed for all purposes to be a LIBOR Quoted
Currency or a Non-LIBOR Quoted Currency, as applicable, for purposes of any
Letter of Credit issuances. If the Administrative Agent shall fail to obtain
consent to any request for an additional currency under this Section 1.06, the
Administrative Agent shall promptly so notify the Company. Any specified
currency of an Existing Letter of Credit that is neither Dollars nor one of the
Alternative Currencies specifically listed in the definition of “Alternative
Currency” shall be deemed an Alternative Currency with respect to such Existing
Letter of Credit only.

(c) Section 2.09. Clause (i) in Section 2.09(a) of the Credit Agreement is
hereby amended to read as follows:

(i) each Eurocurrency Rate Loan shall bear interest on the outstanding principal
amount thereof for each Interest Period at a rate per annum equal to the sum of
the Eurocurrency Rate for such Interest Period plus the Applicable Rate;

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

(d) Section 3.03. Section 3.03 of the Credit Agreement is hereby amended to read
as follows:

(a) Committed Loans. If in connection with any request for a Committed Loan that
is a Eurocurrency Rate Loan or a conversion to or continuation thereof, (i) the
Administrative Agent determines that (A) deposits (whether in Dollars or an
Alternative Currency) are not being offered to banks in the applicable offshore
interbank market for such currency for the applicable amount and Interest Period
of such Eurocurrency Rate Loan, or (B) adequate and reasonable means do not
exist for determining the Eurocurrency Base Rate for any requested Interest
Period with respect to a proposed Eurocurrency Rate Loan (whether denominated in
Dollars or an Alternative Currency) or in connection with an existing or
proposed Base Rate Loan (in each case with respect to clause (i), “Impacted
Committed Loans”), or (ii) the Administrative Agent or the Required Lenders
determine that for any reason the Eurocurrency Base Rate for any requested
Interest Period with respect to a proposed Eurocurrency Rate Loan does not
adequately and fairly reflect the cost to such Lenders of funding such Loan, the
Administrative Agent will promptly so notify the Company and each Lender.
Thereafter, (x) the obligation of the Lenders to make or maintain Committed
Loans that are Eurocurrency Rate Loans in the affected currency or currencies
shall be suspended (to the extent of the affected Eurocurrency Rate Loans or
Interest Periods) and (y) in the event of a determination described in the
preceding sentence with respect to the Eurocurrency Base Rate component of the
Base Rate, the utilization of the Eurocurrency Base Rate component in
determining the Base Rate shall be suspended, in each case until the
Administrative Agent (upon the instruction of the Required Lenders) revokes such
notice. Upon receipt of such notice, the Company may revoke any pending request
for a Borrowing of, conversion to or continuation of Eurocurrency Rate Loans in
the affected currency or currencies or, failing that, will be deemed to have
converted such request into a request for a Borrowing of Base Rate Loans in the
amount specified therein.

(b) Canadian Loans. If in connection with any request for a Canadian Loan that
is a Eurocurrency Rate Loan or a BA Rate Loan or a conversion to or continuation
thereof, (i) the Administrative Agent determines that (A) deposits are not being
offered to banks in the applicable interbank market for such currency for the
applicable amount and Interest Period of such Canadian Loan or (B) adequate and
reasonable means do not exist for determining the Eurocurrency Base Rate or BA
Rate for any requested Interest Period with respect to a proposed Canadian Loan
or in connection (the “Impacted Canadian Loans” and collectively with the
Impacted Committed Loans, the “Impacted Loans”) or (ii) the Administrative Agent
or the Canadian Lender determine that for any reason the Eurocurrency Base Rate
or the BA Rate for any requested Interest Period with respect to a proposed
Canadian Loan does not adequately and fairly reflect the cost to the Canadian
Lender of funding such Canadian Loan, the Canadian Lender will promptly so
notify the Canadian Borrower and the Administrative Agent. Thereafter, the
obligation of the Canadian Lender to make or maintain Eurocurrency Rate Loans or
BA Rate Loans, as applicable, shall be suspended (to the extent of the affected
Canadian Loans or Interest Periods) until the Canadian Lender revokes such
notice. Upon receipt of such notice, the Canadian Borrower may revoke any
pending request for a Borrowing of, conversion to or continuation of
Eurocurrency Rate Loans or BA Rate Loans or, failing that, will be deemed to
have converted such request into a request for a Borrowing of Base Rate Loans in
the amount specified therein.

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

(c) Notwithstanding the foregoing, if the Administrative Agent has made the
determination described in clause (a)(i) or (b)(i) of this Section, the
Administrative Agent in consultation with the Company and the Required Lenders,
may establish an alternative interest rate for the Impacted Loans, in which
case, such alternative rate of interest shall apply with respect to the Impacted
Loans until (1) the Administrative Agent revokes the notice delivered with
respect to the Impacted Loans under clause (a)(i) or (b)(i) of this Section,
(2) the Administrative Agent or the Required Lenders notify the Company that
such alternative interest rate does not adequately and fairly reflect the cost
to the Lenders of funding the Impacted Loans, or (3) any Lender determines that
any Law has made it unlawful, or that any Governmental Authority has asserted
that it is unlawful, for such Lender or its applicable Lending Office to make,
maintain or fund Loans whose interest is determined by reference to such
alternative rate of interest or to determine or charge interest rates based upon
such rate or any Governmental Authority has imposed material restrictions on the
authority of such Lender to do any of the foregoing and provides the
Administrative Agent and the Company written notice thereof.

(e) Section 3.04. Clauses (i) and (iii) of Section 3.04(a) of the Credit
Agreement are hereby amended to read as follows:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory
loan, insurance charge, assessment or similar requirement against assets of,
deposits with or for the account of, or credit extended or participated in by,
any Lender (except any reserve requirement contemplated by Section 3.04(e),
other than as set forth below) or the L/C Issuer;

******

(iii) [reserved]; or

(f) Section 3.04. A new Section 3.04(e) is hereby added to the Credit Agreement
to read as follows:

(e) Mandatory Costs and Additional Reserve Requirements. If any Lender or L/C
Issuer incurs any Mandatory Costs attributable to the Obligations, then from
time to time the Company will pay to such Lender or the L/C Issuer, as the case
may be, such Mandatory Costs. Such amount shall be expressed as a percentage
rate per annum and shall be payable on the full amount of the applicable
Obligations. The Company shall pay to each Lender, as long as such Lender shall
be required to comply with any reserve ratio requirement (excluding any such
requirement reflected in the Eurocurrency Reserve Percentage) or analogous
requirement of any central banking or financial regulatory authority imposed in
respect of the maintenance of the Commitments or the funding of the Eurocurrency
Rate Loans, such additional costs (expressed as a percentage per annum and
rounded upwards, if necessary, to the nearest five decimal places) equal to the
actual costs allocated to such Commitment or Loan by such Lender (as determined
by such Lender in good faith, which determination shall be conclusive), which
shall be due and payable on each date on which interest is payable on such Loan,
provided the Company shall have received at least 10 days’ prior notice (with a
copy to the Administrative Agent) of such additional costs from such Lender. If
a Lender fails to give notice 10 days prior to the relevant Interest Payment
Date, such additional costs shall be due and payable 10 days from receipt of
such notice.

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

(g) Section 4.08. A new Section 4.08 is hereby added to the Credit Agreement
immediately following Section 4.07 of the Credit Agreement to read as follows:

4.08 Keepwell.

Each Loan Party that is a Qualified ECP Guarantor at the time the Guaranty in
this Article IV by any Loan Party that is not then an “eligible contract
participant” under the Commodity Exchange Act (a “Specified Loan Party”) becomes
effective with respect to any Swap Obligation, hereby jointly and severally,
absolutely, unconditionally and irrevocably undertakes to provide such funds or
other support to each Specified Loan Party with respect to such Swap Obligation
as may be needed by such Specified Loan Party from time to time to honor all of
its obligations under the Loan Documents in respect of such Swap Obligation
(but, in each case, only up to the maximum amount of such liability that can be
hereby incurred without rendering such Qualified ECP Guarantor’s obligations and
undertakings under this Article IV voidable under applicable Debtor Relief Laws,
and not for any greater amount). The obligations and undertakings of each
Qualified ECP Guarantor under this Section shall remain in full force and effect
until the Obligations have been indefeasibly paid and performed in full. Each
Loan Party intends this Section to constitute, and this Section shall be deemed
to constitute, a “keepwell, support, or other agreement” for the benefit of each
Specified Loan Party for all purposes of the Commodity Exchange Act.

(h) Section 9.03. The following sentence is hereby added at the end of
Section 9.03 of the Credit Agreement to read as follows:

Excluded Swap Obligations with respect to any Loan Party shall not be paid with
amounts received from such Loan Party or such Loan Party’s assets, but
appropriate adjustments shall be made with respect to payments from other Loan
Parties to preserve the allocation to Obligations otherwise set forth above in
this Section.

(i) Section 11.01. Section 11.01(a)(vi) of the Credit Agreement is hereby
amended to read as follows:

(vi) amend Section 1.06 or the definitions of “Alternative Currency”, “LIBOR
Quoted Currency” or “Non-LIBOR Quoted Currency” without the written consent of
each Lender that is obligated to make Credit Extensions to the Borrowers in
Alternative Currencies; or

(j) Schedule 1.01A. Schedule 1.01A of the Credit Agreement is hereby deleted.

2. Effectiveness; Conditions Precedent. This Amendment shall be effective upon
satisfaction of the following conditions precedent:

(a) Receipt by the Administrative Agent of copies of this Amendment duly
executed by the Borrowers, the Guarantors and the Lenders.

(b) Receipt by the Administrative Agent of a certificate of a Responsible

Parties, in form and substance reasonably satisfactory to the Administrative

or prior to the Business Day immediately preceding the date hereof.

3. Ratification of Credit Agreement. Each of the Loan Parties acknowledges and
consents to the terms set forth herein and agrees that this Amendment does not
impair, reduce or limit any of its obligations under the Loan Documents, except
as expressly amended by this Amendment. This Amendment shall constitute a Loan
