PRELIMINARY STATEMENTS
          (1) The Administrative Agent, the Collateral Agent and the Lenders
have entered into that certain Seventh Amended and Restated Credit Agreement,
dated as of the date hereof (said Agreement, as it may hereafter be amended or
otherwise modified from time to time, being the “Credit Agreement”, the terms
defined therein and not otherwise defined herein being used herein as therein
defined), with the Pledgor.
          (2) The Pledgor and the Administrative Agent have previously entered
into that certain Cash Collateral Agreement, dated as of August 3, 2005 (as
amended, restated, supplemented or otherwise modified prior to the date hereof,
the “Existing Agreement”) pursuant to which cash collateral is deposited by the
Administrative Agent in a special non-interest-bearing cash collateral account
(the “Account”) with the Collateral Agent at its office at 388 Greenwich Street,
New York, New York 10013, Account No. 30579578 (or at such other office of the
Collateral Agent as the Collateral Agent may, from time to time, notify the
Pledgor and the Administrative Agent), in the name of the Pledgor but under the
sole control and dominion of the Collateral Agent and subject to the terms of
this Agreement and the Credit Agreement.
          (3) The Pledgor and the Administrative Agent have agreed to amend and
restate the Existing Agreement pursuant to this Agreement.
          NOW THEREFORE, in consideration of the premises and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Pledgor hereby agrees with the Collateral Agent and the
Administrative Agent, for their benefit and the ratable benefit of the Lenders
and the LC Issuer, as follows:
          SECTION 1. Pledge and Assignment. The Pledgor hereby pledges and
assigns to the Collateral Agent, for its benefit and the ratable benefit of the
Administrative Agent, the Lenders and the LC Issuer, and grants to the
Collateral Agent, for its benefit and the ratable benefit of the Administrative
Agent, the Lenders and the LC Issuer, a security interest in, the following
collateral (collectively, the “Collateral):
     (i) the Account, all funds held therein and all certificates and
instruments, if any, from time to time representing or evidencing the Account;

 

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

 

     (ii) all Investments (as hereinafter defined) from time to time, and all
certificates and instruments, if any, from time to time representing or
evidencing the Investments;
     (iii) all notes, certificates of deposit, deposit accounts, checks and
other instruments from time to time hereafter delivered to or otherwise
possessed by the Collateral Agent for or on behalf of the Pledgor in
substitution for or in addition to any or all of the then existing Collateral;
     (iv) all interest, dividends, cash, instruments and other property from
time to time received, receivable or otherwise distributed in respect of or in
exchange for any or all of the then existing Collateral; and
     (v) all proceeds of any and all of the foregoing Collateral.
          SECTION 2. Security for Obligations. This Agreement secures the
payment of all reimbursement obligations of the Pledgor now or hereafter
existing with respect to LC Outstandings and all obligations of the Pledgor now
or hereafter existing under this Agreement (all such obligations of the Pledgor
being the “Secured Obligations”). Without limiting the generality of the
foregoing, this Agreement secures the payment of all amounts which constitute
part of the Secured Obligations and which remain outstanding after the
Commitment Termination Date or otherwise would be owed by the Pledgor to the
Administrative Agent, the Collateral Agent or the Lenders under the Credit
Agreement and the Promissory Notes (if any) but for the fact that they are
unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving the Pledgor.
          SECTION 3. Delivery of Collateral. All certificates or instruments, if
any, representing or evidencing the Collateral shall be delivered to and held by
or on behalf of the Collateral Agent pursuant hereto and shall be in suitable
form for transfer by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, all in form and substance
satisfactory to the Collateral Agent. The Collateral Agent shall have the right,
at any time upon the occurrence and during the continuance of an Event of
Default, in its discretion and without notice to the Pledgor, to transfer to or
to register in the name of the Collateral Agent or any of its nominees any or
all of the Collateral. In addition, the Collateral Agent shall have the right at
any time to exchange certificates or instruments representing or evidencing
Collateral for certificates or instruments of smaller or larger denominations.
          SECTION 4. Maintaining the Account. So long as any LC Obligation shall
remain unpaid, any Letter of Credit shall remain outstanding or any Lender shall
have any Commitment:
     (a) The Pledgor will maintain the Account with the Collateral Agent.
     (b) It shall be a term and condition of the Account, notwithstanding any
term or condition to the contrary in any other agreement relating to the Account
and except as otherwise provided by the provisions of Sections 6, 13 and 17,

released to or for the account of, or

applicable regulations of the Board of Governors of the Federal Reserve System
and of any other appropriate banking or governmental authority, as may now or
hereafter be in effect.

referred to in clause (a) above, and reinvest other proceeds of any such
Permitted Investments which may mature or be sold, in each case in such
Permitted Investments as the Pledgor may select and the Administrative Agent may
approve (the Permitted Investments referred to in clauses (a) and (b) above,
being collectively “Investments”). Interest and proceeds that are not invested
or reinvested in Investments as provided above shall be deposited and held in
the Account.
          SECTION 6. Release of Amounts. So long as no Event of Default or
Default shall have occurred and be continuing, the Collateral Agent will pay and

(a) amounts of credit balance of the Account and of principal of any other
Collateral when matured or sold to the extent that (i) the sum of the credit

other Collateral exceeds (ii) the aggregate Dollar Equivalent of the LC
Outstandings in respect of all Letters of Credit and all other amounts owing by
the Pledgor hereunder, (b) all amounts in the Account if (i) the aggregate of

maintenance of the security interest created hereby (including the first

Collateral Agent of its rights and remedies hereunder.
     (d) There are no conditions precedent to the effectiveness of this
Agreement that have not been satisfied or waived.

from time to time, at the expense of the Pledgor, the Pledgor will promptly
execute and deliver all further instruments and documents, and take all further
action, that may be necessary or desirable, or that the Collateral Agent may
reasonably request, in order to perfect and protect any security interest
granted or purported to be granted hereby or to enable the Collateral Agent to
exercise and enforce its rights and remedies hereunder with respect to any
Collateral.
          SECTION 9. Transfers and Other Liens. The Pledgor agrees that it will
not (i) sell, assign (by operation of law or otherwise) or otherwise dispose of,
or grant any option with respect to, any of the Collateral, or (ii) create or

encumbrance upon or with respect to any of the Collateral, except for the
security interest under this Agreement.

of an Event of Default or Default or otherwise to the extent that the Collateral

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

 

     SECTION 12. The Collateral Agent’s Duties. The powers conferred on the
Collateral Agent hereunder are solely to protect its interest in the Collateral
and shall not impose any duty upon it to exercise any such powers. Except for
the safe custody of any Collateral in its possession and the accounting for
moneys actually received by it hereunder, the Collateral Agent shall have no
duty as to any Collateral, as to ascertaining or taking action with respect to
calls, conversions, exchanges, maturities, tenders or other matters relative to
any Collateral, whether or not the Administrative Agent, the Collateral Agent or
any Lender has or is deemed to have knowledge of such matters, or as to the
taking of any necessary steps to preserve rights against any parties or any
other rights pertaining to any Collateral. The Collateral Agent shall be deemed
to have exercised reasonable care in the custody and preservation of any
Collateral in its possession if such Collateral is accorded treatment
substantially equal to that which the Collateral Agent accords its own property.
     SECTION 13. Remedies upon Default. If any Event of Default shall have
occurred and be continuing:
     (a) The Collateral Agent may, and shall at the direction of the
Administrative Agent, without notice to the Pledgor except as required by law
and at any time or from time to time, charge, set-off and otherwise apply all or
any part of the Account against the Secured Obligations or any part thereof.
     (b) The Collateral Agent may also exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein or otherwise available
to it, all the rights and remedies of a secured party on default under the
Uniform Commercial Code in effect in the State of New York at that time (the
“Code”) (whether or not the Code applies to the affected Collateral), and may
also, without notice except as specified below, sell the Collateral or any part
thereof in one or more parcels at public or private sale, at any of the
Collateral Agent’s offices or elsewhere, for cash, on credit or for future
delivery, and upon such other terms as the Collateral Agent may deem
commercially reasonable. The Pledgor agrees that, to the extent notice of sale
shall be required by law, at least ten days’ notice to the Pledgor of the time
and place of any public sale or the time after which any private sale is to be
made shall constitute reasonable notification. The Collateral Agent shall not be
obligated to make any sale of Collateral regardless of notice of sale having
been given. The Collateral Agent may adjourn any public or private sale from
time to time by announcement at the time and place fixed therefor, and such sale
may, without further notice, be made at the time and place to which it was so
adjourned.
     (c) Any cash held by the Collateral Agent as Collateral and all cash
proceeds received by the Collateral Agent in respect of any sale of, collection
from, or other realization upon all or any part of the Collateral may, in the
discretion of the Administrative Agent, be held by the Collateral Agent as
collateral for, and/or then or at any time thereafter be applied (after payment
of any amounts payable to the Collateral Agent pursuant to Section 14) in whole
or in part by the Administrative Agent for its benefit and the ratable benefit
of the Collateral Agent, the Lenders and the LC Issuer against, all or any part
of the Secured Obligations in such order as the Administrative Agent shall
elect. Any surplus of such cash or cash proceeds held by the Collateral

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

 

Agent and remaining after payment in full of all the Secured Obligations shall
be paid over to the Pledgor or to whomsoever may be lawfully entitled to receive
such surplus.
          SECTION 14. Expenses. The Pledgor will upon demand pay to the
Collateral Agent and the Administrative Agent the amount of any and all
reasonable expenses, including the reasonable fees and expenses of its counsel
and of any experts and agents, which the Collateral Agent or the Administrative
Agent may incur in connection with (i) the administration of this Agreement,
(ii) the custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Collateral, (iii) the exercise or enforcement of
any of the rights of the Administrative Agent, the Collateral Agent or the
Lenders hereunder or (iv) the failure by the Pledgor to perform or observe any
of the provisions hereof.
          SECTION 15. Amendments, Etc. No amendment or waiver of any provision
of this Agreement, and no consent to any departure by the Pledgor herefrom shall
in any event be effective unless the same shall be in writing and signed by the
Administrative Agent and the Collateral Agent and, in the case of any amendment
hereof, the Pledgor, and then such waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given.
          SECTION 16. Addresses for Notices. All notices and other
communications provided for hereunder shall be made and delivered in accordance
with Section 11.02 of the Credit Agreement.
          SECTION 17. Continuing Security Interest; Assignments under Credit
Agreement. This Agreement shall create a continuing security interest in the
Collateral and shall (i) remain in full force and effect until the later of
(x) the payment in full of the Secured Obligations and the expiration or
termination of each Letter of Credit and (y) the expiration or termination of
the Commitments under the Credit Agreement, (ii) be binding upon the Pledgor,
its successors and assigns, and (iii) inure to the benefit of, and be
enforceable by, the Administrative Agent, the Collateral Agent, the Lenders, the
LC Issuer and their respective successors, transferees and assigns. Without
limiting the generality of the foregoing clause (iii), any Lender may assign or
otherwise transfer all or any portion of its rights and obligations under the
Credit Agreement (including, without limitation, all or any portion of its
Commitment, the Loans owing to it and any Promissory Notes held by it) to any
other Person, and such other Person shall thereupon become vested with all the
benefits in respect thereof granted to such Lender herein or otherwise, subject,
however, to the provisions of Article X (concerning the Agents) and
Section 11.07 of the Credit Agreement. Upon the later to occur of (x) the
payment in full of the Secured Obligations and the expiration or termination of
each Letter of Credit and (y) the expiration or termination of the Commitments
under the Credit Agreement, the security interest granted hereby shall terminate
and all rights to the Collateral shall revert to the Pledgor. Upon any such
termination, the Collateral Agent will, at the Pledgor’s expense, return to the
Pledgor such of the Collateral as shall not have been sold or otherwise applied
pursuant to the terms hereof and execute and deliver to the Pledgor such
documents as the Pledgor shall reasonably request to evidence such termination.
          SECTION 18. Governing Law; Terms. THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE

6

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

 

STATE OF NEW YORK, EXCEPT TO THE EXTENT THAT PERFECTION OF THE SECURITY INTEREST
