COMMITMENTS

Section 2.1                                Commitments.

(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.

Section 2.2                                Fees.

(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

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

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

(e)                      any exchange, release or nonperfection of any
Collateral or other collateral, or any release, amendment or waiver of or

(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

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

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.

C.           PAYMENT 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.

ARTICLE 3.
YIELD PROTECTION

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.

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

ARTICLE 9.
THE ADMINISTRATIVE AGENT

Section 9.1                                Authorization and 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
Credit Documents; (d) shall not have any duty to ascertain or to inquire as to
the performance or observance of any of the terms, covenants or conditions of
any Credit Document on the part of any Credit Party or to inspect the property
(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.

Section 9.8                                No Other Duties, Etc
. Notwithstanding anything in this Agreement to the contrary, no co-lead
arranger, syndication agent or co-documentation agent (each a “Titled Agent”)
listed on the cover page of this Agreement or in the recital of parties to this
Agreement shall have any powers, duties, liabilities or responsibilities under
this Agreement or any of the other Credit Documents, except in its capacity, as
applicable, as the Administrative Agent, a Lender or 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 Section 1.1.

Document and although such obligations may be unmatured. Each Lender agrees to
notify the Borrower and the Administrative Agent promptly after any such setoff
and application made by such Lender; provided, however, that the failure to give

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

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

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

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

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 10.10                                GOVERNING LAW
. THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF CALIFORNIA APPLICABLE TO CONTRACTS
MADE AND PERFORMED IN THE STATE OF CALIFORNIA.

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 10.12                                Headings
. The section and subsection headings used herein have been inserted for
convenience of reference only and do not constitute matters to be considered in
interpreting this Agreement.

Section 10.13                                Execution in Counterparts
. This 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 Terrorism,” and (b) the Patriot Act.

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.

Section 10.16                                Amendment and 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.

(b)                      The Securities Account Control Agreements and the
Lockbox Agreement shall remain in 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.

Section 10.17                                WAIVER OF JURY TRIAL
. TO THE EXTENT PERMITTED BY LAW, EACH OF THE BORROWER, THE LENDERS, THE
ADMINISTRATIVE AGENT, THE COLLATERAL AGENT AND THE TITLED AGENTS HEREBY
IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM, WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE, RELATING TO THIS
AGREEMENT OR ANY OF THE OTHER CREDIT DOCUMENTS, ANY NEGOTIATIONS OR
COMMUNICATIONS RELATING TO THIS AGREEMENT OR ANY OF THE OTHER CREDIT DOCUMENTS
OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY.

Section 10.18                                Judicial 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 (the “Parties”) hereby agree that all Claims (as defined
below), including any and all questions of law or fact relating thereto, shall,
at the written request of any Party, be determined by Reference (as defined
below) as provided below.

(i)           The opposing Parties shall select a single neutral referee, who
shall be a retired state or federal judge. In the event that the opposing
Parties cannot agree upon a referee, the referee shall be appointed by a court
of competent jurisdiction.

(ii)           Except 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.
