    (a)                      Each
Lender agrees severally, on the terms and conditions contained in this
Agreement, to extend credit to the Borrower from time to time from the Closing
Date to the Commitment Termination Date by making funded advances to the
Borrower (the “Advances”)
pursuant to Section 2.4 and participating in letters of credit issued for the
account of the Borrower (the “Letters of
Credit”) pursuant to Section 2.9, in an aggregate amount not to exceed at
any time outstanding such Lender’s Commitment; provided, however, that the sum
of (i) the aggregate principal amount of all Advances outstanding, (ii) the
aggregate Letter of Credit Amount of all Letters of Credit outstanding and (iii)
the aggregate amount of unreimbursed drawings under all Letters of Credit shall
not exceed the Maximum Aggregate Commitment at any time; and further provided, however, that the sum
of (i) the aggregate principal amount of all Advances outstanding, (ii) the
Letter of Credit Usage and (iii) the aggregate amount of unreimbursed drawings
under all Letters of Credit shall not exceed the Borrowing Base at any time.
Within the limits of each Lender’s Commitment, the Borrower may borrow under
Section 2.4, have Letters of Credit issued for the Borrower’s account under
Section 2.9, prepay Advances under Section 2.7, reborrow under Section 2.4, and
have additional Letters of Credit issued for the Borrower’s account under
Section 2.9 after the expiration of previously issued Letters of
Credit.

    

    (b)                      The
Borrower may request from time to time that the Maximum Aggregate Commitment be
increased on any Business Day occurring after the Closing Date (each a “Commitment
Increase Date”), by one or more of the Lenders increasing their
Commitments and/or by one or more new lenders establishing commitments under
this Agreement. The Borrower shall make each such request in writing, not later
than 10 Business Days before the proposed Commitment Increase Date, by
delivering to the Administrative Agent a request (a “Commitment
Increase Request”) signed by an Authorized Officer and specifying the
requested Commitment Increase Date and the aggregate amount of the requested
increase, which shall be in an amount that would not cause the Maximum Aggregate
Commitment to exceed $650,000,000. Promptly after receipt of each Commitment
Increase Request, and provided that the Administrative Agent approves the
requested increase in the Maximum Aggregate Commitment (which approval shall not
be unreasonably withheld or delayed), the Administrative Agent will notify each
Lender of the contents thereof, and each Lender will thereafter (within 10
Business Days after receipt of such notice from the Administrative Agent) notify
the Administrative Agent in writing of such Lender’s willingness, if any, to
accept all or a portion of the requested increase (any such willing Lender
herein called an “Accepting
Lender”). Upon receipt of responses from the Lenders (with any Lender
failing to respond within the specified time period being deemed to have
declined to accept any of the requested increase), the Administrative Agent will
notify the Borrower thereof, and the increase in the Maximum Aggregate
Commitment shall be allocated, at the discretion of the Administrative Agent
after consultation with the Borrower, to each Accepting Lender and to one or
more new lenders (each a “New
Lender”) designated by the Borrower with the consent of the
Administrative Agent. Upon fulfillment of the applicable conditions set forth in
Article 4, on the specified Commitment Increase Date (i) the Maximum Aggregate
Commitment shall be increased by the aggregate amount agreed to by any Accepting
Lenders and/or New Lenders with respect to the Borrower’s request for such an
increase on that date, (ii) each such Accepting Lender’s Commitment shall be
increased in accordance with the foregoing, (iii) each such New Lender shall
become a party to this Agreement with a Commitment established in accordance
with the foregoing, (iv) the interests of the Lenders (including any New
Lenders) in all outstanding Advances and Letters of Credit shall be pro rata in accordance with
their Commitments hereunder as of such Commitment Increase Date, and (v) the
Lenders shall make all appropriate adjustments directly among themselves with
respect to any Advances outstanding under, and any payments under, this
Agreement for periods before such Commitment Increase Date.

    

    (c)                      The
Borrower shall have the right, upon at least 7 Business Days’ notice to the
Administrative Agent, to terminate in whole or reduce ratably in part the unused
portions of the respective Commitments of the Lenders; provided, however, that each
partial reduction shall be in the aggregate amount of $5,000,000 or an integral
multiple of $5,000,000 in excess thereof.

    (a)                      From
the date hereof until the Commitment Termination Date, the Borrower will pay to
the Administrative Agent, for the account of the Lenders, a commitment fee at
the Applicable Commitment Fee Rate in effect from time to time on the actual
daily amount by which the Maximum Aggregate Commitment exceeds the sum of (i)
the aggregate face amount of all Letters of Credit outstanding plus (ii) the
aggregate amount of all Advances outstanding. The commitment fee payable
hereunder shall be payable quarterly in arrears on the first Business Day of
each January, April, July and October, commencing on October 1, 2008, and on the
Commitment Termination Date; provided, however, that on
October 1, 2008 the Borrower will pay a commitment fee in accordance with
Section 2.2(a) of the Old Credit Agreement with respect to periods before the
Closing Date.

    

    (b)                      The
Borrower will pay to each of UBOC and BNP Paribas, for its own account, the fees
payable by the Borrower pursuant to the Fee Letters.

    

    (c)                      All
fees payable by the Borrower under the Credit Documents shall be deemed to be
fully earned when paid and shall be nonrefundable.

    

    Section
2.3                                Mandatory Prepayment of
Advances and Pledge of Cash Collateral

    . If at
any time (a) the sum of (i) the aggregate principal amount of all Advances
outstanding, (ii) the aggregate Letter of Credit Amount of all Letters of Credit
outstanding and (iii) the aggregate amount of unreimbursed drawings under all
Letters of Credit exceeds the Maximum Aggregate Commitment, or if at any time
(b) the sum of (i) the aggregate principal amount of all Advances outstanding,
(ii) the Letter of Credit Usage and (iii) the aggregate amount of unreimbursed
drawings under all Letters of Credit exceeds the Borrowing Base, then, in either
case, the Borrower will immediately, without notice or request by the
Administrative Agent or the Lenders, prepay the Advances (together with accrued
and unpaid interest to the date of prepayment on the principal amount prepaid)
and/or pledge additional cash collateral to the Collateral Agent to secure
reimbursement of amounts available to be drawn under outstanding Letters of
Credit, in an aggregate amount equal to such excess.

    

    A.           ADVANCES

    

    Section
2.4                                Making
Advances.

    

    (a)                      Each
Borrowing shall be made on notice, given (i) with respect to any Borrowing
consisting of Reference Rate Advances, not later than 1:30 p.m., Los Angeles
time, on the Business Day before the date of the proposed Borrowing, (ii) with
respect to any Borrowing consisting of Base Rate Advances, not later than 9:30
a.m., Los Angeles time, on the Business Day before the date of the proposed
Borrowing and (iii) with respect to any Borrowing consisting of LIBOR Advances,
not later than 9:30 a.m., Los Angeles time, on the third Business Day before the
date of the proposed Borrowing, each such notice to be given by the Borrower to
the Administrative Agent, which shall give each Lender prompt notice thereof by
telecopier. Each such notice of a Borrowing shall be in writing in the form of
Exhibit D (a “Notice of
Borrowing”), or by telephone confirmed promptly in writing, by an
Authorized Officer, specifying (A) the requested date of such Borrowing (which
shall be a Business Day), (B) the requested Type of Advances making up such
Borrowing, (C) the requested aggregate amount of such Borrowing, which shall be
$1,000,000 (or, in the case of a Borrowing consisting of LIBOR Advances,
$2,000,000) or an integral multiple of $500,000 in excess thereof, (D) in the
case of a Borrowing consisting of LIBOR Advances or Base Rate Advances, the
requested initial Interest Period for such Advances and (E) the fact that the
statements set forth in Section 4.3(b) are true as of the date of such
Borrowing. Each Lender shall, before 11:00 a.m., Los Angeles time, on the day of
such Borrowing, make available to the Administrative Agent at its address in Los
Angeles referred to in Section 10.2, in immediately available funds, such
Lender’s ratable portion of such Borrowing. After the Administrative Agent’s
receipt of such funds and upon fulfillment of the applicable conditions set
forth in Article 4, the Administrative Agent will make such funds available to
the Borrower by crediting the Borrower’s concentration account number 0880412175
at the Administrative Agent’s aforesaid address. Notwithstanding the provisions
of the first sentence of this Section 2.4(a), if the Borrower gives the
Administrative Agent notice, by telephone confirmed promptly by telecopier, of a
Borrowing consisting of Reference Rate Advances by 9:30 a.m., Los Angeles time,
on the day of the proposed Borrowing, the Administrative Agent and the Lenders
will use commercially reasonable efforts (but shall not be obligated) to make
such Advances available on the day on which such notice is given; provided, however, that the
Administrative Agent and the Lenders shall no longer be required to use
commercially reasonable efforts as described in this sentence if the
Administrative Agent, at its sole option exercisable at any time, gives the
Borrower notice of the same.

    

    (b)                      Notwithstanding
anything in Section 2.4(a) to the contrary, the Borrower may not select LIBOR
Advances for any Borrowing if (i) the obligation of the Lenders to make LIBOR
Advances is then suspended pursuant to Article 3 or (ii) after giving effect to
such Borrowing, the aggregate number of different Interest Periods for
outstanding LIBOR Advances would be greater than 5 (provided that Interest
Periods of the same duration, but commencing on different dates, shall be
treated as different Interest Periods).

    

    (c)                      Each
Notice of Borrowing shall be irrevocable and binding on the Borrower. The
Borrower will indemnify each Lender against any loss, cost or expense incurred
by such Lender as a result of any failure to fulfill, on or before the date
specified for such Borrowing in the related Notice of Borrowing, the applicable
conditions set forth in Article 4, including any loss (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund the
Advance to be made by such Lender as part of such Borrowing when such Advance,
as a result of such failure, is not made on such date.

    

    (d)                      Unless
the Administrative Agent receives notice from a Lender before the date of any
Borrowing that such Lender will not make available to the Administrative Agent
such Lender’s ratable portion of such Borrowing, the Administrative Agent may
assume that such Lender has made such portion available to the Administrative
Agent on the date of such Borrowing in accordance with Section 2.4(a), and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower on such date a corresponding amount. If and to the extent that such
Lender has not made such ratable portion available to the Administrative Agent,
such Lender and the Borrower severally agree to repay to the Administrative
Agent forthwith on demand such corresponding amount, together with interest
thereon, for each day from the date on which such amount is made available to
the Borrower until the date on which such amount is repaid to the Administrative
Agent, at (i) in the case of the Borrower, the interest rate applicable at the
time to the Advances making up such Borrowing and (ii) in the case of such
Lender, the Federal Funds Rate. If such Lender repays to the Administrative
Agent such corresponding amount, such amount so repaid shall constitute such
Lender’s Advance as part of such Borrowing for purposes of this
Agreement.

    

    (e)                      The
failure of any Lender to make the Advance to be made by it as part of any
Borrowing shall not relieve any other Lender of its obligation, if any,
hereunder to make its Advance on the date of such Borrowing, but no Lender shall
be responsible for the failure of any other Lender to make the Advance to be
made by such other Lender on the date of any Borrowing.

    

    Section
2.5                                Repayment

    .  On
the Commitment Termination Date, the Borrower will repay to the Administrative
Agent, for the account of the Lenders, the outstanding principal amount of the
Advances.

    

    Section
2.6                                Interest.

    

    (a)                      The
Borrower will pay interest on the unpaid principal amount of each Advance, from
the date of such Advance (or, if later, the date hereof) until such principal
amount has been paid in full, (i) during such periods as such Advance is a
Reference Rate Advance, at a rate per annum equal at all times
to the sum of the Reference Rate in effect from time to time plus the Applicable
Reference Rate Margin, payable monthly in arrears on the first Business Day of
each calendar month during such periods and on the Commitment Termination Date,
(ii) during such periods as such Advance is a LIBOR Advance, at a rate per annum equal at all times
during each Interest Period for such Advance to the sum of LIBOR for such
Interest Period for such Advance plus the Applicable LIBOR Margin, payable on
the last day of such Interest Period and, in the case of any 6-month Interest
Period, on the day that is 3 months from the first day of such Interest Period,
and (iii) during such periods as such Advance is a Base Rate Advance, at a rate
per annum equal at all
times during each Interest Period for such Advance to the sum of the Base Rate
for such Interest Period for such Advance plus the Applicable Base Rate Margin,
payable on the last day of such Interest Period; provided, however, that the
Borrower will pay interest in accordance with Section 2.6(a) of the Old Credit
Agreement with respect to periods before the Closing Date.

    

    (b)                      Any
amount of principal of any Advance that is not paid when due (whether at stated
maturity, by required prepayment, by acceleration or otherwise) shall bear
interest, from the date on which such amount is due until such amount is paid in
full, payable on demand, at a rate per annum (the “Default
Rate”) equal at all times to the sum of the otherwise applicable interest
rate plus 3.00% per
annum.

    

    (c)                      The
Administrative Agent will give prompt notice to the Borrower and the Lenders of
each applicable interest rate determined by the Administrative Agent for
purposes of Section 2.6(a).

    

    (d)                      If
the Borrower fails to select the duration of any Interest Period for any LIBOR
Advances or Base Rate Advances in accordance with the provisions contained in
the definition of “Interest Period” in Section 1.1, the Administrative Agent
will forthwith so notify the Borrower and the Lenders, and such Advances shall
automatically, on the last day of the then existing Interest Period therefor,
Convert into Reference Rate Advances.

    

    (e)                      If
any amount, other than principal of any Advance, payable by the Borrower under
this Agreement or any other Credit Document is not paid when due (whether at
stated maturity, by acceleration or otherwise), then, to the fullest extent
permitted by applicable Governmental Rules, such amount shall bear interest,
from the date on which such amount is due until such amount is paid in full,
payable on demand, at a rate per annum equal at all times
to the sum of the interest rate applicable to Reference Rate Advances from time
to time plus 3.00% per
annum.

    

    Section
2.7                                Optional
Prepayments

    . The
Borrower may on any Business Day, in the case of Reference Rate Advances or Base
Rate Advances upon prior written notice not later than 9:30 a.m., Los Angeles
time, on the day of any prepayment of such Advances, and in the case of LIBOR
Advances upon at least 3 Business Days’ prior written notice, to the
Administrative Agent stating the proposed date and aggregate principal amount of
the prepayment, and if such notice is given the Borrower will, prepay the
outstanding principal amounts of the Advances making up a Borrowing in whole or
ratably in part, together, in the case of LIBOR Advances or Base Rate Advances,
with accrued and unpaid interest to the date of such prepayment on the principal
amount prepaid; provided, however, that any
prepayment of LIBOR Advances or Base Rate Advances shall be made on, and only
on, the last day of an Interest Period for such Advances; and further provided, however, that each
partial prepayment shall be in the aggregate principal amount of $1,000,000 or
an integral multiple of $500,000 in excess thereof.

    

    Section
2.8                                Conversion of
Advances.

    

    (a)                      The
Borrower may on any Business Day, upon prior written notice in the form of
Exhibit E (a “Notice of
Conversion/Continuation”) signed by an Authorized Officer and given to
the Administrative Agent (i) with respect to any Conversion from Base Rate
Advances to Reference Rate Advances or from Reference Rate Advances to Base Rate
Advances, not later than 9:30 a.m., Los Angeles time, on the Business Day
immediately preceding the date of the proposed Conversion and (ii) with respect
to any Conversion from or to LIBOR Advances, not later than 9:30 a.m., Los
Angeles time, on the third Business Day before the date of the proposed
Conversion, subject to the provisions of Sections 2.4(b), 3.2 and 3.3, Convert
all the Advances of one Type making up the same Borrowing into Advances of
another Type; provided, however, that any
Conversion of LIBOR Advances or Base Rate Advances into Advances of another Type
shall be made on, and only on, the last day of an Interest Period for such LIBOR
Advances or Base Rate Advances. Each Notice of Conversion shall, within the
restrictions specified above, specify (A) the date of such Conversion, (B) the
Advances to be Converted and (C) if such Conversion is into LIBOR Advances or
Base Rate Advances, the duration of the initial Interest Period for such
Advances. Each Notice of Conversion shall be irrevocable and binding on the
Borrower. The Administrative Agent shall give each Lender prompt notice by
telecopier of each Notice of Conversion.

    

    (b)                      On
any date on which the aggregate unpaid principal amount of LIBOR Advances
composing any Borrowing is reduced, by payment or prepayment or otherwise, to
less than $2,000,000, such Advances shall automatically Convert into Reference
Rate Advances. Upon the occurrence and during the continuation of any Default,
(i) each LIBOR Advance and Base Rate Advance shall automatically, on the last
day of the then existing Interest Period therefor, Convert into a Reference Rate
Advance, and (ii) the obligation of the Lenders to make, or to Convert Advances
into, LIBOR Advances or Base Rate Advances shall be suspended.

    

    B.           LETTERS OF
CREDIT

    

    Section
2.9                                Issuance of Letters of
Credit.

    

    (a)                      Subject
to the limitations set forth in Section 2.1(a), the Borrower shall be entitled
to request the issuance of Letters of Credit, from time to time from the Closing
Date to the Commitment Termination Date (subject to the second-to-last sentence
of this Section 2.9(a)), by giving either Issuing Bank a Letter of Credit
Request at least 1 Business Day before the requested date of issuance of each
such Letter of Credit (which shall be a Business Day).  Any Letter of
Credit Request received by an Issuing Bank later than 3:00 p.m., Los Angeles
time, shall be deemed to have been received on the next Business Day. Each
Letter of Credit Request shall be delivered by telecopier (but shall be deemed
to be an original for all purposes), shall be signed by an Authorized Officer,
shall be irrevocable and shall be effective upon receipt by the applicable
Issuing Bank. Provided that a valid Letter of Credit Request has been received
by the applicable Issuing Bank and upon fulfillment of the other applicable
conditions set forth in Article 4, such Issuing Bank will issue the requested
Letter of Credit; provided, however, that neither
Issuing Bank shall be obligated to, but each may in its sole and absolute
discretion, issue a Letter of Credit as requested by the Borrower pursuant
hereto if such issuance would cause the sum of (i) the aggregate Letter of
Credit Amount of all outstanding Letters of Credit issued by such Issuing Bank
and (ii) the aggregate amount of unreimbursed drawings under all Letters of
Credit issued by such Issuing Bank to exceed 50% of the Maximum Aggregate
Commitment. No Letter of Credit may have an expiration date later than the 60th
day before the Commitment Termination Date. Notwithstanding the foregoing
provisions of this Section 2.9(a), if the Borrower gives an Issuing Bank notice,
by telephone confirmed promptly by telecopier, of a request for a Letter of
Credit by noon, Los Angeles time, on the proposed day of issuance of such Letter
of Credit, such Issuing Bank will use commercially reasonable efforts (but shall
not be obligated) to issue such Letter of Credit on the day on which such notice
is given; provided, however, that an
Issuing Bank shall no longer be required to use commercially reasonable efforts
as described in this sentence if such Issuing Bank, at its sole option
exercisable at any time, gives the Borrower notice of the same.

    

    (b)                      Immediately
upon the issuance of each Letter of Credit by an Issuing Bank, such Issuing Bank
shall be deemed to have sold and transferred to each other Lender, and each
other Lender shall be deemed to have purchased and received from such Issuing
Bank, in each case irrevocably and without any further action by any party, an
undivided interest and participation in such Letter of Credit, each drawing
thereunder and the obligations of the Borrower under this Agreement in respect
thereof in an amount equal to the product of (i) a fraction the numerator of
which is the amount of the Commitment of such Lender and the denominator of
which is the Maximum Aggregate Commitment and (ii) the maximum amount available
to be drawn under such Letter of Credit (assuming compliance with all conditions
to drawing). Each Issuing Bank will promptly advise each other Lender of the
issuance of each Letter of Credit by such Issuing Bank, the Letter of Credit
Amount of such Letter of Credit, any change in the face amount or expiration
date of such Letter of Credit, the cancellation or other termination of such
Letter of Credit and any drawing under such Letter of Credit.

    

    Section
2.10                                Drawing and
Reimbursement.

    

    (a)                      The
Borrower will reimburse each Issuing Bank for the amount of each draft presented
under a Letter of Credit and paid by such Issuing Bank and any taxes, fees,
charges or other costs or expenses reasonably incurred by such Issuing Bank in
connection with such payment. Each such reimbursement shall be effected by a
Reference Rate Advance from such Issuing Bank in accordance with Section
2.10(b).  Each Issuing Bank will notify the Borrower promptly of each
payment by such Issuing Bank of a draft presented under a Letter of
Credit.

    

    (b)                      The
payment by an Issuing Bank of a draft presented under a Letter of Credit shall
constitute for all purposes of this Agreement the making by such Issuing Bank of
a Reference Rate Advance in the amount of such payment, without any requirement
of compliance with the provisions of Section 2.1(a), Section 2.4(a) or Article 4
and without regard to whether the Commitment Termination Date has occurred, but
subject to the provisions of Section 2.3. In the event that any such Reference
Rate Advance by an Issuing Bank is not repaid by the Borrower by 11:00 a.m., Los
Angeles time, on the first Business Day after the day on which such Reference
Rate Advance was made, such Issuing Bank will promptly so notify the
Administrative Agent and each other Lender. On the first Business Day after such
notification, each such Lender will make a Reference Rate Advance, which shall
be used to repay the applicable portion of the relevant Issuing Bank’s Reference
Rate Advance with respect to such drawing, in an amount equal to the amount of
such Lender’s participation in such drawing and will make available to the
Administrative Agent for such Issuing Bank’s account, in immediately available
funds, the amount of such Reference Rate Advance. Each such Lender’s obligation
to make such a Reference Rate Advance shall be absolute and unconditional in all
circumstances, without any requirement of compliance with the provisions of
Section 2.1(a), Section 2.4(a) or Article 4 and without regard to whether the
Commitment Termination Date has occurred, but subject to the provisions of
Section 2.3. If and to the extent that any such Lender fails to make the amount
of such Reference Rate Advance available to the Administrative Agent, for the
account of such Issuing Bank, such Lender and the Borrower severally agree to
repay such amount to the Administrative Agent, for the account of such Issuing
Bank, forthwith on demand, together with interest thereon for each day from the
date on which such amount was made available to the Borrower by such Issuing
Bank until the date on which such amount is repaid to the Administrative Agent,
for the account of such Issuing Bank, at (i) in the case of the Borrower, the
interest rate applicable at the time to Reference Rate Advances and (ii) in the
case of such Lender, the Federal Funds Rate. If such Lender repays such amount
to the Administrative Agent, for the account of such Issuing Bank, such amount
so repaid shall constitute such Lender’s Reference Rate Advance to the Borrower
for purposes of this Section 2.10(b).

    

    Section
2.11                                Obligations
Absolute

    . The
obligations of the Borrower under this Agreement, any Letter of Credit Request
and any other agreement or instrument relating to any Letter of Credit shall be
absolute, unconditional and irrevocable and shall be paid strictly in accordance
with the terms of the aforementioned documents under all circumstances,
including the following:

    

    (a)                      any
lack of validity or enforceability of any Letter of Credit, this Agreement or
any other Credit Document;

    

    (b)                      the
existence of any claim, setoff, defense or other right that the Borrower may
have at any time against any beneficiary or transferee of any Letter of Credit
(or any Person for whom any such beneficiary or transferee may be acting),
either Issuing Bank, any other Lender (other than the defense of payment in
accordance with the terms of this Agreement) or any other Person, whether in
connection with this Agreement, any other Credit Document, the transactions
contemplated hereby or thereby or any unrelated transaction;

    

    (c)                      any
statement or other document presented under any Letter of Credit proving to be
forged, fraudulent, invalid or insufficient in any respect, or any statement
therein being untrue or inaccurate in any respect whatsoever;

    

    (d)                      payment
by an Issuing Bank under any Letter of Credit against presentation of a draft or
certificate that does not comply with the terms of such Letter of
Credit;

    

    (e)                      any
exchange, release or nonperfection of any Collateral or other collateral, or any
release, amendment or waiver of or consent to departure from the Guaranty or any
other guaranty, for any of the Obligations of the Borrower in respect of the
Letters of Credit; and

    

    (f)                      any
other circumstance or happening whatsoever, whether or not similar to any of the
foregoing.

    

    Section
2.12                                Letter of Credit Fees and
Charges.

    

    (a)                      The
Borrower will pay to the Administrative Agent, for the account of the Lenders,
from and including the date hereof to the date on which all Letters of Credit
have expired or been terminated, a letter of credit fee (the “Letter of Credit
Fee”) at the Applicable LOC Fee Rate in effect from time to time on the
aggregate of the actual daily Letter of Credit Amounts of all Letters of Credit
outstanding from time to time; provided, however, that, to the
extent and so long as no Event of Default has occurred and is continuing and the
Borrower pledges cash collateral to the Collateral Agent pursuant to the
Security Agreement by depositing such cash collateral into account number
4560001520 of the Collateral Agent at UBOC, Los Angeles, California, as
collateral for, and in the amount of, the Borrower’s contingent reimbursement
obligations in respect of all or a portion of the aggregate Letter of Credit
Amount of the Letters of Credit outstanding from time to time, then the Letter
of Credit Fee payable on all or such portion, as applicable, of the aggregate of
the actual daily Letter of Credit Amounts of such Letters of Credit shall be
payable at the rate of 0.75% per annum. The Letter of
Credit Fee shall be payable monthly in arrears on the first Business Day of each
calendar month, commencing on September 1, 2008, to the extent accrued during
the immediately preceding calendar month; provided, however, that on
September 1, 2008 the Borrower will pay a letter of credit fee in accordance
with Section 2.12(a) of the Old Credit Agreement with respect to periods before
the Closing Date.

    

    (b)                      The
Borrower will pay to each Issuing Bank for its own account such additional fees
and charges (including cable charges) as are generally associated with letters
of credit, in accordance with such Issuing Bank’s standard internal charge
guidelines in effect from time to time.

    

    Section
2.13                                Limits of Liability of
Issuing Banks and Lenders.

    

    (a)                      The
Borrower agrees to the provisions in the Letter of Credit Request forms; provided, however, that the
terms of this Agreement shall take precedence if there is any inconsistency
between the terms of this Agreement and the terms of either such
form.

    

    (b)                      The
Borrower assumes all risks of the acts or omissions of any beneficiary or
transferee of any Letter of Credit with respect to its use of such Letter of
Credit. Neither Issuing Bank nor any other Lender nor any of their respective
officers or directors shall be liable or responsible for (i) the use that may be
made of any Letter of Credit or any acts or omissions of any beneficiary or
transferee in connection therewith, (ii) the validity, sufficiency or
genuineness of documents, or of any endorsement thereof, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent or
forged, (iii) payment by an Issuing Bank against presentation of documents that
do not comply with the terms of any Letter of Credit, including failure of any
documents to bear any reference or adequate reference to any Letter of Credit,
or (iv) any other circumstance whatsoever in making or failing to make payment
under any Letter of Credit; provided, however, that (A) the
Borrower shall have a claim against an Issuing Bank, and such Issuing Bank shall
be liable to the Borrower, to the extent of any direct, but not consequential,
damages suffered by the Borrower that the Borrower proves were caused by (1)
such Issuing Bank’s willful misconduct or gross negligence in determining
whether documents presented under any Letter of Credit issued by such Issuing
Bank comply with the terms of such Letter of Credit or (2) such Issuing Bank’s
willful failure to make lawful payment under any Letter of Credit issued by such
Issuing Bank after the presentation thereto by the beneficiary or transferee of
such Letter of Credit of a draft and certificates strictly complying with the
terms and conditions of such Letter of Credit, and (B) EXCEPT AS EXPRESSLY PROVIDED IN
CLAUSE (A) ABOVE, THE BORROWER SHALL HAVE NO CLAIM AGAINST EITHER ISSUING BANK,
AND NEITHER ISSUING BANK SHALL BE LIABLE TO THE BORROWER, FOR ANY DAMAGES
SUFFERED BY THE BORROWER THAT ARE IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE
OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY SUCH ISSUING
BANK. In furtherance and not in limitation of the foregoing, an Issuing
Bank may accept any document that appears on its face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary.

PROVISIONS

    

    Section
2.14                                Payments.

    

    (a)                      The
Borrower will make each payment hereunder and under the Notes not later than
11:00 a.m., Los Angeles time, on the day when due, in U.S. dollars and
immediately available funds, to the Administrative Agent at its address in Los
Angeles set forth in Section 10.2. The Administrative Agent will promptly
thereafter cause to be distributed like funds relating to the payment of
principal, interest or fees ratably (other than amounts payable pursuant to
Section 2.2(b) or Article 3 or interest payable to an Issuing Bank in respect of
a Reference Rate Advance made thereby pursuant to Section 2.10(b)) to the
Lenders and like funds relating to the payment of any other amount payable to
any Lender to such Lender, in each case to be applied in accordance with the
terms of this Agreement. Upon its acceptance of an Assignment and Assumption and
recording of the information contained therein in the Register pursuant to
Section 10.8(d), from and after the effective date of such Assignment and
Assumption the Administrative Agent will make all payments hereunder in respect
of the interest assigned thereby to the Lender assignee thereunder, and the
parties to such Assignment and Assumption will make all appropriate adjustments
in such payments for periods before such effective date directly between
themselves.

    

    (b)                      The
Borrower hereby authorizes each Lender, if and to the extent that any payment
owed to such Lender is not made when due hereunder or under any other Credit
Document, to charge from time to time against any or all of the Borrower’s
accounts with such Lender any amount so due.

    

    (c)                      Unless
the Administrative Agent receives notice from the Borrower before the date on
which any payment is due to the Lenders hereunder that the Borrower will not
make such payment in full, the Administrative Agent may assume that the Borrower
has made such payment in full to the Administrative Agent on such date, and the
Administrative Agent may, in reliance upon such assumption, cause to be
distributed to each Lender on such due date an amount equal to the amount then
due to such Lender. If and to the extent that the Borrower has not so made such
payment in full to the Administrative Agent, each Lender will repay to the
Administrative Agent forthwith upon demand such amount distributed to such
Lender, together with interest thereon, for each day from the date on which such
amount was distributed to such Lender until the date on which such Lender repays
such amount to the Administrative Agent, at the Federal Funds Rate.

    

    Section
2.15                                Computation of Interest and
Fees

    .  All
computations of interest and fees hereunder shall be made on the basis of a year
of 360 days for the actual number of days (including the first day but excluding
the last day) occurring in the period for which such interest or fees are
payable. Each determination by the Administrative Agent of an interest rate
hereunder shall be conclusive and binding for all purposes, absent manifest
error.

    

    Section
2.16                                Payments on Non-Business
Days

    .  Whenever
any payment hereunder or under any other Credit Document is stated to be due on
a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fee, as the case may be;
provided, however, that, if
such extension would cause payment of interest on or principal of LIBOR Advances
to be made in the next succeeding calendar month, such payment shall be made on
the next preceding Business Day.

    

    Section
2.17                                Sharing of Payments,
Etc.

      If
any Lender obtains any payment (whether voluntary, involuntary, through the
exercise of any right of setoff or otherwise) on account of the Advances made by
it or the Letters of Credit participated in by it (other than amounts payable
pursuant to Section 2.2(b) or Article 3 or interest payable to an Issuing Bank
in respect of a Reference Rate Advance made thereby pursuant to Section 2.10(b))
in excess of its ratable share of payments on account of the Advances and
Letters of Credit obtained by all of the Lenders, then such Lender will
forthwith purchase from the other Lenders such participations in the Advances
made by them and the Letters of Credit participated in by them as necessary to
cause such purchasing Lender to share the excess payment ratably with each of
them; provided,
however, that,
if all or any portion of such excess payment is thereafter recovered from such
purchasing Lender, such purchase from each other Lender shall be rescinded, and
each such other Lender shall repay to the purchasing Lender the purchase price
to the extent of such recovery, together with an amount equal to such Lender’s
ratable share (according to the proportion of (a) the amount of such Lender’s
required repayment to (b) the total amount so recovered from the purchasing
Lender) of any interest or other amount paid or payable by the purchasing Lender
in respect of the total amount so recovered. The Borrower agrees that any Lender
so purchasing a participation from another Lender pursuant to this section may,
to the fullest extent permitted by law, exercise all of its rights of payment
(including the right of setoff) with respect to such participation as fully as
if such Lender were the direct creditor of the Borrower in the amount of such
participation.

    

    Section
2.18                                Evidence of
Debt.

    

    (a)                      The
indebtedness of the Borrower resulting from all Advances made by each Lender
from time to time shall be evidenced by the Notes.

    

    (b)                      The
books and accounts of the Administrative Agent shall be conclusive evidence,
absent manifest error, of all Letter of Credit Amounts and of the amounts of all
Advances, drawings under Letters of Credit, reimbursements under Letters of
Credit, repayments of Advances, fees, interest and other charges advanced, due,
outstanding or paid pursuant to this Agreement or any other Credit
Document.

    

    Section
2.19                                Continuation of Outstanding
Credit

    .  On
the Closing Date, any “Advances” and “Letters of Credit” outstanding under the
Old Credit Agreement shall be deemed to be Advances and Letters of Credit,
respectively, outstanding under this Agreement; provided, however, that (a) the
interests of the Lenders in such Advances and Letters of Credit shall be pro rata in accordance with
their Commitments hereunder as of the Closing Date and (b) the Lenders shall
make all appropriate adjustments directly among themselves with respect to any
“Advances” outstanding under, and any payments under, the Old Credit Agreement
for periods before the Closing Date.

    Section
3.1                                Increased LIBOR Advance
Costs

    .  If,
due to either (a) the introduction of or any change (other than any change by
way of imposition or increase of reserve requirements, in the case of LIBOR
Advances, included in the LIBOR Reserve Percentage) in or in the interpretation
of any Governmental Rule or (b) compliance with any Governmental Rule (whether
or not having the force of law), there is an increase in the cost to any Lender
of agreeing to make, making, funding or maintaining any LIBOR Advance, then the
Borrower will from time to time, upon demand by such Lender (with a copy of such
demand to the Administrative Agent), pay to the Administrative Agent, for the
account of such Lender, additional amounts sufficient to compensate such Lender
for such increased cost. A certificate as to the amount of such increased cost,
submitted to the Borrower and the Administrative Agent by such Lender, shall be
conclusive and binding for all purposes, absent manifest error.

    

    Section
3.2                                Illegality

    .  Notwithstanding
any other provision of this Agreement, if the introduction of, or any change in
or in the interpretation of, any Governmental Rule makes it unlawful, or any
Governmental Person asserts that it is unlawful, for any Lender to perform its
obligations hereunder to make LIBOR Advances or to continue to fund or maintain
LIBOR Advances hereunder, then, on notice thereof and demand therefor by such
Lender to the Borrower through the Administrative Agent, (a) the obligation of
such Lender to make LIBOR Advances and to Convert Advances into LIBOR Advances
shall be suspended until the Administrative Agent notifies the Borrower that
such Lender has determined that the circumstances causing such suspension no
longer exist, and (b) the Borrower will forthwith prepay in full all LIBOR
Advances of such Lender then outstanding, together with accrued and unpaid
interest thereon, unless the Borrower, within 5 Business Days of such notice and
demand, Converts all LIBOR Advances of all Lenders then outstanding into
Reference Rate Advances in accordance with Section 2.8(a).

    

    Section
3.3                                Inadequacy of
LIBOR

    .  If,
with respect to any LIBOR Advances, the Majority Lenders notify the
Administrative Agent that LIBOR determined pursuant to Section 2.6(a)(ii) for
any Interest Period for such Advances will not adequately reflect the cost to
the Majority Lenders of making, funding or maintaining their respective LIBOR
Advances for such Interest Period, then the Administrative Agent will forthwith
so notify the Borrower and the Lenders, whereupon (a) all such LIBOR Advances
shall automatically, on the last day of the then existing respective Interest
Periods therefor, Convert into Reference Rate Advances, and (b) the obligations
of the Lenders to make, or to Convert Advances into, LIBOR Advances shall be
suspended until the Administrative Agent notifies the Borrower and the Lenders
that the circumstances causing such suspension no longer exist.

    

    Section
3.4                                Increased Letter of Credit
Costs

    .  If,
after the date hereof, any change in any Governmental Rule or in the
interpretation thereof by any Governmental Person charged with the
administration thereof either (a) imposes, modifies or deems applicable any
reserve, special-deposit or similar requirement against letters of credit or
guaranties issued by or participated in, or assets held by, or deposits in or
for the account of, either Issuing Bank or any other Lender or (b) imposes on
either Issuing Bank or any other Lender any other condition regarding this
Agreement, such Issuing Bank, such Lender or any Letter of Credit, and the
result of any event referred to in the preceding clause (a) or (b) is to
increase the cost to either Issuing Bank of issuing or maintaining any Letter of
Credit or to any Lender of purchasing or maintaining any participation therein,
then, upon demand by such Issuing Bank or Lender through the Administrative
Agent, the Borrower will pay to such Issuing Bank or Lender through the
Administrative Agent, from time to time as specified by such Issuing Bank or
Lender through the Administrative Agent, additional amounts sufficient to
compensate such Issuing Bank or Lender for such increased cost. A certificate as
to the amount of such increased cost, submitted to the Borrower by such Issuing
Bank or Lender, shall be conclusive and binding for all purposes, absent
manifest error.

    

    Section
3.5                                Capital
Adequacy

    .  If
any Lender determines that compliance with any Governmental Rule (whether or not
having the force of law) affects or would affect the amount of capital required
or expected to be maintained by such Lender or any corporation controlling such
Lender and that the amount of such capital is increased by or based upon the
existence of such Lender’s commitment to lend hereunder and other commitments of
this type or the commitment to issue or participate in, or the issuance of or
participation in, the Letters of Credit (or similar contingent obligations),
then, upon demand by such Lender (with a copy of such demand to the
Administrative Agent), the Borrower will pay to the Administrative Agent, for
the account of such Lender, from time to time as specified by such Lender,
additional amounts sufficient to compensate such Lender in the light of such
circumstances, to the extent that such Lender reasonably determines such
increase in capital to be allocable to the existence of such Lender’s commitment
to lend hereunder or commitment to issue or participate in, or the issuance of
or participation in, Letters of Credit. A certificate as to such amounts
submitted to the Borrower by such Lender shall be conclusive and binding for all
purposes, absent manifest error.

    Section
3.6                                Funding
Losses

    .  If
any payment of principal of, or any Conversion of, any LIBOR Advance or Base
Rate Advance is made other than on the last day of an Interest Period for such
Advance, as a result of a payment or Conversion pursuant to Section 3.2 or 3.3
or acceleration of the maturity of the Obligations pursuant to Section 8.1 or
for any other reason, the Borrower will, upon demand by any Lender (with a copy
of such demand to the Administrative Agent), pay to the Administrative Agent,
for the account of such Lender, any amounts required to compensate such Lender
for any additional losses, costs or expenses that it may reasonably incur as a
result of such payment or Conversion, including any loss (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund or
maintain such Advance.

    

    Section
3.7                                Taxes.

    

    (a)                      Any
and all payments by or on account of any obligation of the Borrower under this
Agreement or under any other Credit Document shall be made free and clear of and
without deduction or withholding for any Indemnified Taxes; provided, however, that, if the
Borrower is required by applicable Governmental Rules to deduct any Indemnified
Taxes from such payments, then (i) the amount payable shall be increased as
necessary so that, after making all required deductions (including deductions
applicable to additional amounts payable under this section), the Administrative
Agent or Lender, as the case may be, receives an amount equal to the amount it
would have received had no such deductions been made, (ii) the Borrower will
make such deductions and (iii) the Borrower will timely pay the full amount
deducted to the relevant Governmental Person in accordance with applicable
Governmental Rules.

    

    (b)                      Without
limiting the provisions of Section 3.7(a), the Borrower will timely pay all
Stamp and Excise Taxes to the relevant Governmental Persons in accordance with
applicable Governmental Rules.

    

    (c)                      The
Borrower will indemnify the Administrative Agent and each Lender, within 10 days
after demand therefor, for the full amount of any Indemnified Taxes (including
Indemnified Taxes imposed or asserted on or attributable to amounts payable
under this section) paid by the Administrative Agent or such Lender, as the case
may be, and any penalties, interest and reasonable expenses arising therefrom or
with respect thereto, whether or not such Indemnified Taxes were correctly or
legally imposed or asserted by the relevant Governmental Person. A certificate
as to the amount of such payment or liability delivered to the Borrower by a
Lender (with a copy to the Administrative Agent), or by the Administrative Agent
on its own behalf or on behalf of a Lender, shall be conclusive absent manifest
error.

    

    (d)                      As
soon as practicable after any payment of Indemnified Taxes by the Borrower to a
Governmental Person, the Borrower will deliver to the Administrative Agent the
original or a certified copy of a receipt issued by such Governmental Person
evidencing such payment, a copy of the return reporting such payment or other
evidence of such payment reasonably satisfactory to the Administrative
Agent.

    

    (e)                      Any
Foreign Lender that is entitled to an exemption from or reduction of withholding
tax under the law of the jurisdiction in which the Borrower is resident for tax
purposes or under any treaty to which such jurisdiction is a party, with respect
to payments hereunder or under any other Credit Document, will deliver to the
Borrower (with a copy to the Administrative Agent), at the time or times
prescribed by applicable Governmental Rules or reasonably requested by the
Borrower or the Administrative Agent, such properly completed and executed
documentation prescribed by applicable Governmental Rules as will permit such
payments to be made without withholding or at a reduced rate of withholding. In
addition, any Lender, if requested by the Borrower or the Administrative Agent,
will deliver such other documentation (including an Internal Revenue Service
Form W-9) prescribed by applicable Governmental Rules or reasonably requested by
the Borrower or the Administrative Agent as will enable the Borrower or the
Administrative Agent to determine whether or not such Lender is subject to
backup withholding or information-reporting requirements. Without limiting the
generality of the foregoing, each Foreign Lender will deliver to the Borrower
and the Administrative Agent (in such number of copies as requested by the
recipient), on or before the date on which such Foreign Lender becomes a Lender
under this Agreement (and from time to time thereafter upon the request of the
Borrower or the Administrative Agent, but only if such Foreign Lender is legally
entitled to do so), whichever of the following is applicable:

    

    (i)           duly
completed copies of Internal Revenue Service Form W-8BEN claiming eligibility
for benefits of an income-tax treaty to which the United States of America is a
party;

    

    (ii)           duly
completed copies of Internal Revenue Service Form W-8ECI;

    

    (iii)           in
the case of a Foreign Lender claiming the benefits of the exemption for
portfolio interest under section 881(c) of the Tax Code, (A) a certificate to
the effect that such Foreign Lender is not (1) a “bank” within the meaning of
section 881(c)(3)(A) of the Tax Code, (2) a “10 percent shareholder” of the
Borrower within the meaning of section 881(c)(3)(B) of the Tax Code or (3) a
“controlled foreign corporation” described in section 881(c)(3)(C) of the Tax
Code and (B) duly completed copies of  Internal Revenue Service Form
W-8BEN; or

    

    (iv)           any
other form prescribed by applicable Governmental Rules as a basis for claiming
exemption from or a reduction of United States federal withholding tax, duly
completed, together with such supplementary documentation as may be prescribed
by applicable Governmental Rules to permit the Borrower to determine the
withholding or deduction required to be made.

    

    (f)                      If
the Administrative Agent or a Lender determines, in its sole discretion, that it
has received a refund of any Taxes as to which it has been indemnified by the
Borrower or with respect to which the Borrower has paid additional amounts
pursuant to this section, it will pay to the Borrower an amount equal to such
refund (but only to the extent of indemnity payments made, or additional amounts
paid, by the Borrower under this section with respect to the Taxes giving rise
to such refund), net of all out-of-pocket expenses of the Administrative Agent
or such Lender, as the case may be, and without interest (other than any
interest paid by the relevant Governmental Person with respect to such refund);
provided, however, that, upon
the request of the Administrative Agent or such Lender, the Borrower will repay
the amount paid over to the Borrower (plus any penalties, interest or other
charges imposed by the relevant Governmental Person) to the Administrative Agent
or such Lender in the event that the Administrative Agent or such Lender is
required to repay such refund to such Governmental Person. This section shall
not be construed to require the Administrative Agent or any Lender to make
available its tax returns (or any other information relating to its taxes that
it deems confidential) to the Borrower or any other Person.

    

    Section
3.8                                Substitution of
Lender

    .  If
(a) any Lender demands payment from the Borrower in any material amount pursuant
to Section 3.1, 3.4, 3.5 or 3.7 or (b) any Lender gives notice of illegality
pursuant to Section 3.2, and in either case the event or circumstance causing
such Lender to make such demand or give such notice is not applicable to the
Majority Lenders, then the Borrower shall have the right, with the assistance of
the Administrative Agent, to seek a mutually satisfactory lender or lenders
(which may be one or more of the other Lenders) to substitute for such Lender by
purchasing the Obligations and assuming the Commitment of such Lender; provided, however, that in any
event the Borrower shall be obligated to compensate such Lender pursuant to
Section 3.1, 3.4, 3.5 or 3.7 or to prepay such Lender’s LIBOR Advances pursuant
to Section 3.2, as applicable.

any, specified in the agreement or instrument relating to such Debt; any other
event occurs or condition exists under any agreement or instrument relating to
any such Debt and continues after the applicable grace period, if any, specified
in such agreement or instrument, if the effect of such event or condition is to

proceedings are commenced by any creditor upon such judgment or order or (ii)
there is any period of 10 consecutive days (or, if the entire amount is covered
by insurance (subject to applicable deductibles), 30 consecutive days) during
which a stay of enforcement of such judgment or order, by reason of a pending
appeal or otherwise, is not in effect, unless such judgment or order has been
vacated, satisfied, dismissed, or bonded pending appeal or, in the case of a
judgment or order the entire amount of which is covered by insurance (subject to
applicable deductibles), is the subject of a binding agreement with the
plaintiff and the insurer covering payment therefor;

    

    (g)                      there
occurs, in the reasonable judgment of the Majority Lenders, any material and

party thereto, or such Credit Party so states in writing;

    

    (i)                      for
any reason except to the extent permitted by the terms of the Security Agreement
or the Stock Pledge Agreement, there ceases to be a valid and perfected
first-priority security interest in favor of the Collateral Agent in any of the
Collateral purported to be covered by either of such agreements;

    

    (j)                      an
ERISA Event occurs with respect to a Pension Plan or a Multiemployer Plan that
results, or could reasonably be expected to result, in liability of FOC or any
ERISA Affiliate under Title IV of ERISA to such Pension Plan, such Multiemployer
Plan or the PBGC in an aggregate amount exceeding $10,000,000; or FOC or any
ERISA Affiliate fails to pay when due, after the expiration of any applicable
grace period, any installment payment with respect to its withdrawal liability
under Section 4201 of ERISA under a Multiemployer Plan in an aggregate amount
exceeding $10,000,000; or

    

    (k)                      any
“person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the
Securities Exchange Act of 1934 (the “Exchange
Act”)) becomes, or obtains rights (whether by means of warrants, options
or otherwise) to become, the “beneficial owner” (as defined in Rules 13d-3 and
13d-5 under the Exchange Act), directly or indirectly, of more than 35% of the
outstanding common stock of FOC; the Board of Directors of FOC ceases to consist
of a majority of Continuing Directors; FOC ceases to own and control, of record
and beneficially, directly or indirectly, 100% of each class of outstanding
Capital Stock of the Borrower and each Guarantor, free and clear of all Liens;
or a Specified Change of Control occurs; then, and in any such event, the
Administrative Agent (i) shall at the request, or may with the consent, of the
Majority Lenders, by notice to the Borrower, declare the obligation of each
Lender to make Advances, and the obligation of the Issuing Banks to issue
Letters of Credit, to be terminated, whereupon the same shall forthwith
terminate, and (ii) shall at the request, or may with the consent, of the
Majority Lenders, by notice to the Borrower, declare the Obligations, all
interest thereon and all other amounts payable under this Agreement and the
other Credit Documents to be forthwith due and payable, whereupon (A) the
Obligations, all such interest and all such amounts shall become and be
forthwith due and payable, without presentment, demand, protest or further
notice of any kind, all of which are hereby expressly waived by the Borrower,
and (B) to the extent any Letters of Credit are then outstanding, the Borrower
will deposit with and pledge to the Collateral Agent cash collateral in the
aggregate Letter of Credit Amount of such Letters of Credit, on terms and
conditions, and subject to documentation, reasonably satisfactory to the
Collateral Agent and the Issuing Banks; provided, however, that, in the
event of an actual or deemed entry of an order for relief with respect to any
Credit Party or any Subsidiary under the United States Bankruptcy Code, (1) the
obligation of each Lender to make Advances and of the Issuing Banks to issue
Letters of Credit shall be terminated automatically, and (2) the Advances, all
such interest and all such amounts (including such cash collateral) shall
automatically become and be due and payable, without presentment, demand,
protest or any notice of any kind, all of which are hereby expressly waived by
the Borrower.

the exercise of remedies provided for in Section 8.1 and the other Credit

payable and the Borrower has automatically been required to provided cash
collateral as provided in Section 8.1), any amounts received on account of the
Obligations shall be applied by the Administrative Agent in the following
order:

    

    (a)                      first,
to payment of that portion of the Obligations constituting fees, indemnities,
expenses and other amounts (including fees, charges and disbursements of counsel
to the Administrative Agent and amounts payable under Article 3) payable to the
Administrative Agent for its own account;

    

    (b)                      second,
to payment of that portion of the Obligations constituting fees, indemnities,

(including fees, charges and disbursements of counsel to the respective Lenders
and Issuing Banks and amounts payable under Article 3), ratably among the
Lenders and Issuing Banks in proportion to the respective amounts described in
this clause (b) payable to them;

    

    (c)                      third,
without duplication of amounts applied pursuant to clauses (a) and (b) above, to
payment of that portion of the Obligations constituting accrued and unpaid
Letter of Credit Fees and interest on the Advances and other Obligations,
ratably among the Lenders and Issuing Banks in proportion to the respective
amounts described in this clause (c) payable to them;

    

    (d)                      fourth,
to payment of that portion of the Obligations constituting unpaid principal of
the Advances, unreimbursed draws under Letters of Credit and amounts owing under
Secured Hedge Agreements and Secured Cash Management Agreements, ratably among
the Lenders, the Issuing Banks, the Hedge Banks and the Cash Management Banks in
proportion to the respective amounts described in this clause (d) held by
them;

    

    (e)                      fifth,
to the Administrative Agent for the account of the Issuing Banks and the other
Lenders, to cash-collateralize the aggregate undrawn amount of all outstanding
Letters of Credit;

    

    (f)                      sixth,
to the payment of any other Obligations owing to the Administrative Agent, the
Issuing Banks and the other Lenders and any interest accrued thereon;
and

    

    (g)                      last,
the balance, if any, after all of the Obligations have been indefeasibly paid in
full, to the Borrower or as otherwise required by applicable Governmental
Rules.

    

    Amounts
used to cash-collateralize the aggregate undrawn amount of outstanding Letters
of Credit pursuant to clause (e) above shall be applied to satisfy drawings
under such Letters of Credit as they occur. If any amount remains on deposit as
cash collateral after all Letters of Credit have either been fully drawn or
terminated, such remaining amount shall be applied to the other Obligations, if
any, in the order set forth above.

Action

    . Each
Lender hereby appoints and authorizes the Administrative Agent to take such
action as agent on its behalf and to exercise such powers under this Agreement
as are delegated to the Administrative Agent by the terms hereof, together with
such powers as are reasonably incidental thereto.  As to any matters
not expressly provided for by the Credit Documents (including enforcement of and
collection under the Credit Documents), the Administrative Agent shall not be
required to exercise any discretion or take any action but shall be required to
act or refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the instructions of the Majority Lenders, and such
instructions shall be binding upon all Lenders and all holders of Notes; provided, however, that the
Administrative Agent shall not be required to take any action that exposes the
Administrative Agent to personal liability or that is contrary to the Credit
Documents or applicable Governmental Rules. The Administrative Agent agrees to
give each Lender prompt notice of each notice given to it by the Borrower
pursuant to the terms of this Agreement.

    

    Section
9.2                                Administrative Agent’s
Reliance, Etc.

      Neither
the Administrative Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them under
or in connection with the Credit Documents, except for its or their own gross
negligence or willful misconduct. Without limitation of the generality of the
foregoing, the Administrative Agent (a) may treat any Lender that has signed
this Agreement, an Assignment and Assumption or a Joinder Agreement as the
holder of the applicable portion of the Obligations; (b) may consult with legal
counsel (including legal counsel for any Credit Party), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the
advice of such legal counsel, accountants or experts; (c) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any
statements, warranties or representations made in or in connection with the

(including the books and records) of any Credit Party; (e) shall not be
responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of any Credit Document or any
other instrument or document furnished pursuant thereto; and (f) shall incur no
liability under or in respect of any Credit Document by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telecopier
or otherwise) believed by it to be genuine and signed or sent by the proper
party or parties.

    

    Section
9.3                                UBOC and
Affiliates

    . With
respect to its Commitment, the Advances made by it, the Note issued to it and
the Letters of Credit participated in by it, UBOC shall have the same rights and
powers under this Agreement as any other Lender and may exercise the same as
though it were not the Administrative Agent; and the term “Lender” or “Lenders”
shall, unless otherwise expressly indicated, include UBOC in its individual
capacity (including in its capacity as an Issuing Bank). UBOC and its Affiliates
may accept deposits from, lend money to, act as trustee under indentures of, and
generally engage in any kind of business with, any Credit Party, any Subsidiary
and any Person that may do business with or own securities of any Credit Party
or any Subsidiary, all as if UBOC were not the Administrative Agent and without
any duty to account therefor to the Lenders.

    

    Section
9.4                                Lender Credit
Decision

    . Each
Lender acknowledges that it has, independently and without reliance on the
Administrative Agent or any other Lender and based on the financial statements
referred to in Sections 5.5 and 6.4 and such other documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement. Each Lender also acknowledges that it will, independently
and without reliance on the Administrative Agent or any other Lender and based
on such documents and information as it deems appropriate at the time, continue
to make its own credit decisions in taking or not taking action under this
Agreement.

    

    Section
9.5                                Indemnification

    . The
Lenders agree to indemnify the Administrative Agent (to the extent not promptly
reimbursed by the Borrower), ratably according to the respective principal
amounts of the Obligations then held by each of them (or, if no Obligations are
at the time outstanding or if any Obligations are then held by Persons that are
not Lenders, ratably according to the respective amounts of their Commitments),
from and against all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses and disbursements of any kind or
nature whatsoever that may be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of any of the Credit
Documents or any action taken or omitted by the Administrative Agent under any
of the Credit Documents; provided, however, that (a) no
Lender shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Administrative Agent’s gross negligence or willful misconduct
and (b) SUCH INDEMNITY SHALL
APPLY WHETHER OR NOT ANY SUCH LIABILITY, OBLIGATION, LOSS, DAMAGE, PENALTY,
ACTION, JUDGMENT, SUIT, COST, EXPENSE OR DISBURSEMENT IS IN ANY WAY OR TO ANY
EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION (OTHER THAN
ANY CONSTITUTING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF ANY KIND BY THE
ADMINISTRATIVE AGENT. Without limitation of the foregoing, each Lender
agrees to reimburse the Administrative Agent promptly upon demand for its
ratable share of any costs and expenses payable by the Borrower under Section
10.4, to the extent that the Administrative Agent is not promptly reimbursed for
such costs and expenses by the Borrower. The failure of any Lender to make any
payment required to be made by it to the Administrative Agent under this Section
9.5 shall not relieve any other Lender of its obligation to make such a payment
to the Administrative Agent hereunder, but no Lender shall be responsible for
the failure of any other Lender to make the payment required to be made by such
other Lender hereunder.

    

    Section
9.6                                Successor Administrative
Agent

    . The
Administrative Agent may resign at any time by giving written notice thereof to
the Lenders, FOC and the Borrower and may be removed at any time with or without
cause with the written approval of the Majority Lenders. Upon any such
resignation or removal, the Majority Lenders shall have the right to appoint a
successor Administrative Agent. If no successor Administrative Agent has been so
appointed by the Majority Lenders, and has accepted such appointment, within 30
days after the retiring Administrative Agent’s giving of notice of resignation
or the Majority Lenders’ removal of the retiring Administrative Agent, then the
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a commercial bank organized under the laws
of the United States of America or of any state thereof and having a combined
capital and surplus of at least $500,000,000.  Upon the acceptance of
any appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all of the rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations under the Credit Documents. After any retiring
Administrative Agent’s resignation or removal hereunder as Administrative Agent,
the provisions of this Article 9 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was administrative agent under this
Agreement.

    

    Section
9.7                                Collateral
Agent.

    

    (a)           Except
for action expressly required of the Collateral Agent hereunder or under any
other Credit Document, the Collateral Agent shall in all cases be fully
justified in refusing to act hereunder and thereunder unless it is further
indemnified to its satisfaction by the Lenders and the Hedge Banks,
proportionately in accordance with the Obligations then due and payable to each
of them, against all liability and expense that may be incurred by the
Collateral Agent by reason of taking or continuing to take any such
action.

    

    (b)                      Except
as expressly provided herein or in any other Credit Document, the Collateral
Agent shall have no duty to take any affirmative steps with respect to the
collection of amounts payable in respect of the Collateral. The Collateral Agent
shall incur no liability as a result of any private sale of the
Collateral.

    

    (c)                      The
Lenders and the Hedge Banks hereby consent, and agree upon written request by
the Collateral Agent to execute and deliver such instruments and other documents
as the Collateral Agent may deem desirable to confirm such consent, to the
release of the Liens on the Collateral, including any release in connection with
any sale, transfer or other disposition of the Collateral or any part thereof,
in accordance with the Credit Documents.

    

    (d)                      The
Collateral Agent shall be deemed to have exercised reasonable care in the
custody and preservation of the Collateral in its possession if the Collateral
is accorded treatment substantially equal to that the Collateral Agent accords
its own similar property, it being understood that neither the Collateral Agent
nor any Lender or Hedge Bank shall have responsibility for (i) ascertaining or
taking action with respect to calls, conversions, exchanges, maturities, tenders
or other matters relative to any Collateral, whether or not the Collateral Agent
or any Lender or Hedge Bank is deemed to have knowledge of such matters, or (ii)
taking any necessary steps to preserve rights against any parties with respect
to any Collateral.

    

    (e)                      The
Collateral Agent shall have, with respect to the Hedge Banks, the duties and
responsibilities expressly set forth in this Agreement and the other Credit
Documents, and no others, and the Collateral Agent shall not by reason of this
Agreement or any other Credit Document be an agent or a trustee for, or have any
fiduciary obligation to, any Hedge Bank.

syndication agent or co-documentation agent (each a “Titled
Agent”) listed on the cover page of this Agreement or in the recital of

responsibilities under this Agreement or any of the other Credit Documents,

an Issuing Bank hereunder and except that BNP Paribas, in its capacity as
Syndication Agent, shall have the rights described in Section 6.2 and in clause
(viii) of the proviso contained in the definition of “Eligible Accounts” in

foregoing indemnity shall not cover any claim of malpractice made by any
Indemnified Party against its own legal counsel. SUCH INDEMNITY SHALL APPLY WHETHER OR
NOT ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST OR EXPENSE IS IN ANY WAY OR TO

failure to give such notice shall not affect the validity of such setoff and
application. The rights of each Lender under this section are in addition to
other rights and remedies (including other rights of setoff) that such Lender
may have.

    

    Section

Participations.

    

    (a)                      Each
Lender may assign to one or more banks or other entities all or a portion of its
rights and obligations under this Agreement (including all or a portion of its
Commitment, the Advances owing to it and its participations in outstanding
Letters of Credit); provided, however, that (i)
except in the case of an assignment to a Person that, immediately before such
assignment, was a Lender, the amount of the Commitment of the assigning Lender
being assigned pursuant to each such assignment (determined as of the date of
the Assignment and Assumption with respect to such assignment) shall in no event
be less than the lesser of (A) the entire Commitment of such Lender at such time
and (B) $15,000,000, (ii) each such assignment shall be subject to the prior
written consent of the Administrative Agent and each Issuing Bank (which
consents may not be unreasonably withheld or delayed), and (iii) the parties to
each such assignment shall execute and deliver to the Administrative Agent, for
its acceptance and recording in the Register, an Assignment and Assumption,
together with a processing and recording fee of $3,500. Upon such consent,
execution, delivery, acceptance and recording, from and after the effective date
specified in the applicable Assignment and Assumption, which effective date
shall be at least 5 Business Days after the date of delivery thereof to the
Administrative Agent or, if so specified in such Assignment and Assumption, the
date of acceptance thereof by the Administrative Agent, (i) the assignee
thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment and
Assumption, shall have the rights and obligations of a Lender hereunder, and
(ii) the Lender assignor thereunder shall, to the extent that rights and
obligations hereunder have been assigned by it pursuant to such Assignment and
Assumption, relinquish its rights and be released from its obligations under
this Agreement (and, in the case of an Assignment and Assumption covering all or
the remaining portion of an assigning Lender’s rights and obligations under this
Agreement, such Lender shall cease to be a party hereto, except that such Lender
shall continue to be an “Indemnified Party” under Section 6.14(b) and an
“Indemnified Person” under Section 10.5).

    

    (b)                      By
executing and delivering an Assignment and Assumption, the Lender assignor
thereunder and the assignee thereunder confirm to and agree with each other and
the other parties hereto as follows: (i) other than as provided in such
Assignment and Assumption, such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to any statement, warranty
or representation made in or in connection with this Agreement or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of this
Agreement or any other instrument or document furnished pursuant hereto; (ii)
such assigning Lender makes no representation or warranty and assumes no
responsibility with respect to the financial condition of any Credit Party or
any Subsidiary or the performance or observance by any Credit Party of any of
its obligations under any Credit Document or any other instrument or document
furnished pursuant hereto; (iii) such assignee confirms that it has received a
copy of this Agreement, together with copies of the financial statements
referred to in Sections 5.5 and 6.4 and such other documents and information as
it has deemed appropriate to make its own credit analysis and decision to enter
into such Assignment and Assumption; (iv) such assignee will, independently and
without reliance upon the Administrative Agent, such assigning Lender or any
other Lender and based on such documents and information as it may deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (v) such assignee appoints and
authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers under the Credit Documents as are delegated to the
Administrative Agent by the terms thereof, together with such powers as are
reasonably incidental thereto; and (vi) such assignee agrees that it will
perform in accordance with their terms all of the obligations that by the terms
of the Credit Documents are required to be performed by it as a
Lender.

    

    (c)                      Any
financial institution that is to become a party to this Agreement as a New
Lender pursuant to Section 2.1(b) must be consented to by the Borrower, the
Administrative Agent and each Issuing Bank (which consents may not be
unreasonably withheld or delayed) and must execute a Joinder Agreement,
consented to by the Borrower, the Administrative Agent and each Issuing Bank and
delivered to the Administrative Agent for its recording in the Register,
together with a processing and recording fee of $3,500; provided, however, that (i)
each New Lender must have a Commitment of at least $15,000,000 and (ii) no
joinder of a New Lender to this Agreement may cause the maximum amount of the
Maximum Aggregate Commitment to exceed $650,000,000. Upon such execution,
consent, delivery and recording, from and after the effective date specified in
the applicable Joinder Agreement, the New Lender thereunder shall be a party
hereto and, to the extent provided in such Joinder Agreement, shall have the
rights and obligations of a Lender hereunder. By executing and delivering a
Joinder Agreement, the New Lender thereunder confirms to and agrees with the
other parties hereto as specified in Sections 10.8(b)(iii) through (vi), as if
it were an assignee (but without reference to an assignor). Upon the joinder of
any New Lender to this Agreement pursuant to this Section 10.8(c), the
Administrative Agent shall forward to the Borrower and each Lender an updated
Schedule 1.

    

    (d)                      The
Administrative Agent shall maintain at its address set forth in Section 10.2 a
copy of each Assignment and Assumption and Joinder Agreement delivered to the
Administrative Agent and consented to as specified above and a register for the
recordation of the names and addresses of the Lenders and the Commitment of, and
the principal amount of Obligations owing to, each Lender from time to time (the
“Register”).
The entries in the Register shall be conclusive and binding for all purposes,
absent manifest error, and the Borrower, the Administrative Agent and the
Lenders may treat each Person whose name is recorded in the Register as a Lender
hereunder for all purposes of this Agreement. The Register shall be available
for inspection by the Borrower or any Lender at any reasonable time and from
time to time upon reasonable prior notice.

    

    (e)                      Upon
its receipt of an Assignment and Assumption or a Joinder Agreement that has been
properly executed and consented to as specified above, the Administrative Agent
shall, if such Assignment and Assumption or Joinder Agreement has been properly
completed and is in proper form, (i) accept such Assignment and Assumption or
Joinder Agreement, (ii) record the information contained therein in the Register
and (iii) give prompt notice thereof to the Borrower.

    

    (f)                      Each
Lender may sell participations to one or more banks or other entities in or to
all or a portion of its rights and obligations under this Agreement (including
all or a portion of its Commitments, the Advances owing to it and its
participations in outstanding Letters of Credit); provided, however, that (i)
such Lender’s obligations under this Agreement (including its Commitment) shall
remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) the Borrower, the
Administrative Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender’s rights and
obligations under this Agreement and (iv) no participant under any such
participation shall have any right to approve any amendment or waiver of any
provision of any Credit Document, or any consent to any departure by any Credit
Party therefrom, except to the extent that such amendment, waiver or consent
would (A) reduce the principal of, or interest on, the Advances, the amount to
be reimbursed in respect of any drawing under a Letter of Credit or any fees or
other amounts payable hereunder, in each case to the extent subject to such
participation, (B) postpone any date fixed for any payment of principal of, or
interest on, the Advances, the amount to be reimbursed in respect of any drawing
under a Letter of Credit or any fees or other amounts payable hereunder, in each
case to the extent subject to such participation, or (C) release all or
substantially all of the Collateral, except as provided in the Credit
Documents.

    

    (g)           Any
Lender or the Administrative Agent may, in connection with any assignment,
joinder or participation or proposed assignment, joinder or participation
pursuant to this Section 10.8, disclose to the assignee, New Lender or
participant or proposed assignee, New Lender or participant any information
relating to the Borrower that was furnished to such Lender or the Administrative
Agent by or on behalf of the Borrower.

    

    (h)                      Nothing
herein shall prohibit any Lender from pledging or assigning any Advance or any
Note to any Federal Reserve Bank in accordance with applicable Governmental
Rules.

    

    Section
10.9                                Disclosure

    . In
addition to disclosure permitted pursuant to Section 10.8(g), the Administrative
Agent and each Lender may disclose to any Person, if with or through such Person
the Administrative Agent or such Lender enters into (or proposes to enter into)
any securitization, hedge or other such transaction relating to, or under which
payments are to be made by reference to, this Agreement or any Credit Party,
such information about any Credit Party or any of the Credit Documents as the
Administrative Agent or such Lender reasonably deems to be necessary in
connection with such transaction.

    Section
10.11                                Limitation on
Interest

    . The
Lenders, the Administrative Agent and the Credit Parties intend to contract in
strict compliance with applicable usury law from time to time in effect, and in
furtherance thereof they stipulate and agree that none of the terms and
provisions contained in the Credit Documents shall ever be construed to create a
contract to pay, for the use, forbearance or detention of money, interest in
excess of the maximum amount of interest permitted to be charged by applicable
Governmental Rules in effect from time to time. No Credit Party or other Person
hereafter becoming liable for payment of any Obligation shall ever be liable for
unearned interest thereon or shall ever be required to pay interest thereon in
excess of the maximum amount that may be lawfully charged under applicable
Governmental Rules in effect from time to time, and the provisions of this
section shall control over all other provisions of the Credit Documents that may
be in conflict or apparent conflict herewith. The Lenders and the Administrative
Agent expressly disavow any intention to charge or collect excessive unearned
interest or finance charges in the event the maturity of any Obligation is
accelerated. If (a) the maturity of any Obligation is accelerated for any
reason, (b) any Obligation is prepaid and, as a result, any amounts held to
constitute interest are determined to be in excess of the legal maximum or (c)
any Lender or other holder of any or all of the Obligations otherwise collects
moneys that are determined to constitute interest that would otherwise increase
the interest on any or all of the Obligations to an amount in excess of that
permitted to be charged by applicable Governmental Rules then in effect, then
all sums determined to constitute interest in excess of such legal limit shall,
without penalty, be promptly applied to reduce the then outstanding principal of
the related Obligations or, at the affected Lender’s or holder’s option,
promptly returned to the Borrower or the other payor thereof upon such
determination. In determining whether or not the interest paid or payable under
any specific circumstances exceeds the maximum amount permitted under applicable
Governmental Rules, the Lenders, the Administrative Agent and the Credit Parties
(and any other payors of such interest) shall, to the greatest extent permitted
under applicable Governmental Rules, (i) characterize any payment of an amount
other than principal as an expense, fee or premium rather than as interest, (ii)
exclude voluntary prepayments and the effects thereof and (iii) amortize,
prorate, allocate and spread the total amount of interest throughout the entire
contemplated term of the instruments evidencing the Obligations in accordance
with the amounts outstanding from time to time thereunder and the maximum legal
rate of interest from time to time in effect under applicable Governmental Rules
in order to lawfully charge the maximum amount of interest permitted under
applicable Governmental Rules.

    

    Section

Agreement may be executed in any number of counterparts and by different parties
hereto in separate counterparts, each of which when so executed shall be deemed
to be an original and all of which taken together shall constitute one and the
same agreement. Delivery by telecopier or e-mail of an executed counterpart of a
signature page to this Agreement shall be effective as delivery of an originally
executed counterpart of this Agreement.

    

    Section
10.14                                USA PATRIOT Act
Notice

    . Each
Lender subject to Title III of the Uniting and Strengthening America by
Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of
2001 (Public Law 107-56) (the “Patriot
Act”) hereby notifies the Borrower that, pursuant to the requirements of
the Patriot Act, such Lender is required to obtain, verify and record
information that identifies the Borrower, which information includes the name
and address of the Borrower and other information that will allow such Lender to
identify the Borrower in accordance with the Patriot Act. This notice is given
in accordance with the requirements of the Patriot Act and is effective as to
each Lender in its capacity as such and in each other capacity in which such
Lender acts under any of the Credit Documents. The Borrower agrees to cooperate
with each Lender, and to provide true, accurate and complete information
thereto, in response to any request by such Lender pursuant to the requirements
of the Patriot Act. The Borrower will take reasonable measures to ensure
compliance with all applicable antiterrorism laws and similar laws, including
(a) Executive Order 13224 of September 23, 2001, entitled “Blocking Property and
Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support

    Section
10.15                                Payments Set
Aside

    . To the
extent that (a) any payment by or on behalf of the Borrower is made to the
Administrative Agent, the Collateral Agent or any Lender or (b) the
Administrative Agent, the Collateral Agent or any Lender exercises its right of
setoff, and such payment or the proceeds of such setoff or any part thereof is
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required (including pursuant to any settlement entered into by the
Administrative Agent, the Collateral Agent or such Lender in its discretion) to
be repaid to a trustee, receiver or any other party, in connection with any
proceeding under the United States Bankruptcy Code or otherwise, then (i) to the
extent of such recovery, the obligation or part thereof originally intended to
be satisfied shall be revived and continued in full force and effect as if such
payment had not been made or such setoff had not occurred, and (ii) each Lender
severally agrees to pay to the Administrative Agent or the Collateral Agent, as
applicable, upon demand its applicable share (without duplication) of any amount
so recovered from or repaid by the Administrative Agent or the Collateral Agent,
as the case may be, plus interest thereon from the date of such demand to the
date such payment is made at the rate per annum equal to the
Federal Funds Rate in effect from time to time. The obligations of the Lenders
under clause (b) of the preceding sentence shall survive the payment in full of
the Obligations and the termination of this Credit Agreement.

Restatement

    .

    

    (a)                      This
Agreement is an amendment and restatement of the Old Credit Agreement. On and
after the Closing Date, any reference in any other Credit Document to “the
Credit Agreement,” “thereunder,” “thereof,” “therein” or words of like import
referring to the Old Credit Agreement shall mean and be a reference to this
Agreement.

full force and effect and are hereby ratified and confirmed.

    

    (c)                      The
execution, delivery and effectiveness of this Agreement shall not operate as a
waiver of any right, power or remedy of the Administrative Agent or any Lender
under any of the Credit Documents or constitute a waiver of any provision of any
of the Credit Documents.

Reference

    .

    

    (a)                      If
the waiver of jury trial set forth in Section 10.17 is not enforceable under
Applicable State Law (as defined below) or otherwise, then the Borrower, the
Lenders, the Administrative Agent, the Collateral Agent and the Titled Agents

as otherwise provided in this Section 10.18, the Reference shall be conducted
pursuant to Applicable State Law. The referee shall determine all issues
relating to the applicability, interpretation, legality and enforceability of
this Section 10.18. The referee shall report a statement of decision to the
appropriate court.

    

    (iii)           No
provision of this Section 10.18 shall limit the right of any Party to (i)
exercise self-help remedies, including setoff, (ii) foreclose against or sell
any Collateral, by power of sale or otherwise, or (iii) obtain or oppose
provisional or ancillary remedies from a court of competent jurisdiction before,
after or during the pendency of the Reference. The exercise of, or opposition
to, any such remedy does not waive the right of any Party to a Reference
pursuant to this Section 10.18.

    

    (iv)           The
Parties hereby acknowledge that, if a referee is selected or appointed to
determine any Claims, then such Claims will not be decided by a
jury.

    

    (b)                      In
the event that punitive damages are permitted under Applicable State Law, the
amount thereof shall not exceed three times the amount of actual
damages.

    

    (c)                      In
the event that any provision of this Section 10.18 is found to be illegal or
unenforceable, the remainder of this Section 10.18 shall remain in full force
and effect.

    

    (d)                      In
the event that multiple Claims are asserted, some of which are not subject to
this Section 10.18, the Parties agree to stay the proceedings of the Claims not
subject to this Section 10.18 until all other Claims are resolved in accordance
with this Section 10.18. In the event that Claims are asserted against multiple
parties, some of which are not subject to this Section 10.18, the Parties agree
to sever the Claims subject to this Section 10.18 and to resolve them in
accordance with this Section 10.18. In the event of any challenge to the
legality or enforceability of this Section 10.18, the prevailing Party or
Parties shall be entitled to recover the costs and expenses, including
reasonable attorneys’ fees, incurred thereby in connection therewith. Applicable
State Law shall govern the interpretation of this Section 10.18. This Section
10.18 fully states the terms and conditions of the Parties’ agreement regarding
the matters mentioned in, or incidental to, this Section 10.18. This Section
10.18 supersedes all oral negotiations and prior writings concerning the subject
matter hereof.

    

    (e)                      As
used in this Section 10.18, the terms set forth below shall have the respective
meanings specified below.

    

    (i)           “Applicable State
Law” means the law of the State of California; provided, however, that, if any
Party seeks to (A) exercise self-help remedies, including setoff, (B) foreclose
against or sell any Collateral, by power of sale or otherwise, or (C) obtain or
oppose provisional or ancillary remedies from a court of competent jurisdiction
before, after or during the pendency of a Reference, then the law of the
appropriate state for exercise of or opposition to the foregoing remedies shall
govern the same.

    

    (ii)           “Claim”
shall mean any claim, cause of action, action, dispute or controversy between or
among the Parties, whether sounding in contract, tort or otherwise, that arises
out of or relates to (A) any of the Credit Documents, (B) any negotiations or
communications relating to any of the Credit Documents, whether or not
incorporated into the Credit Documents or any indebtedness evidenced thereby, or
(C) any alleged agreements, promises, representations or transactions in
connection with any of the foregoing.

    

    (iii)           “Reference”
shall mean a judicial reference conducted pursuant to this Section 10.18 and in
accordance with Applicable State Law, as in effect at the time the referee is
selected or appointed pursuant to Section 10.18(a).
