The parties hereto hereby agree as follows:

SECTION 1. DEFINITIONS

1.1 Defined Terms.  As used in this Agreement, the terms listed in this Section 1.1 shall have the respective meanings set forth in this Section 1.1.

“ABR”:  for any day, a rate per annum (rounded upwards, if necessary, to the next 1/16 of 1%) equal to the greater of (a) the Prime Rate in effect on such day and (b) the Federal Funds Effective Rate in effect on such day plus ½ of 1%.  For purposes hereof, “Prime Rate” shall mean the rate of interest per annum publicly announced from time to time by JPMorgan Chase Bank, N.A. as its prime rate in effect at its principal office in New York City (the Prime Rate not being intended to be the lowest rate of interest charged by JPMorgan Chase Bank, N.A. in connection with extensions of credit to debtors).  Any change in the ABR due to a change in the Prime Rate or the Federal Funds Effective Rate shall be effective as of the opening of business on the effective day of such change in the Prime Rate or the Federal Funds Effective Rate, respectively.

“ABR Loans”:  Revolving Loans the rate of interest applicable to which is based upon the ABR.

“Addendum”:  an instrument, substantially in the form of Exhibit D, by which a Lender becomes a party to this Agreement as of the Closing Date.

“Administrative Agent”:  JPMorgan Chase Bank, N.A., together with its affiliates, as an arranger of the Revolving Commitments and as the administrative agent for the Lenders under this Agreement and the other Loan Documents, together with any of its successors.

“Affiliate”:  as to any Person, any other Person that, directly or indirectly, is in Control of, is Controlled by, or is under common Control with, such Person. 

“Agents”:  the collective reference to the Syndication Agents, the Documentation Agents and the Administrative Agent.

“Aggregate Exposure Percentage”:  with respect to any Lender at any time, the ratio (expressed as a percentage) of such Lender’s Aggregate Exposure at such time to the Aggregate Exposure of all Lenders at such time.

“Agreement”:  as defined in the preamble hereto.

“Applicable Margin”:  The rate per annum set forth under the relevant column heading below based on the applicable Debt Rating:

Level		Debt Rating		Commitment Fee		ABR Loans		Eurodollar Loans/ Letters of Credit
I		>A/A2		0.08	%	0	%	0.30	%
II		A-/A3		0.10	%	0	%	0.375	%
III		BBB+/Baa1		0.125	%	0	%	0.475	%

The Debt Ratings shall be determined from the most recent public announcement of any changes in the Debt Ratings.  If the rating system of S&P or Xxxxx’x shall change, the Borrower and the Administrative Agent shall negotiate in good faith to amend this definition to reflect such changed rating system and, pending the effectiveness of such amendment (which shall require the approval of Required Lenders), the Debt Rating shall be determined by reference to the rating most recently in effect prior to such change.

(b) At any time prior to the fourth anniversary of the Closing Date, the Borrower and any one or more Lenders (including New Lenders) may agree that such Lender(s) shall make, obtain or increase the amount of their Revolving Commitments by executing and delivering to the Administrative Agent an Increased Revolving Commitment Activation Notice specifying the amount of such increase and the applicable Increased Revolving Commitment Closing Date (which may be no later than the fourth anniversary of the Closing Date).  Notwithstanding the foregoing, (i) the aggregate amount of incremental Revolving Commitments obtained pursuant to this Section 2.1(b) shall not exceed $100,000,000, (ii) incremental Revolving Commitments may not be made, obtained or increased after the occurrence and during the continuation of a Default or Event of Default, including after giving effect to the incremental Revolving Commitments in question, (iii) the increase effected pursuant to this paragraph shall be in a minimum amount of at least $25,000,000 and (iv) no more than one Increased Revolving Commitment Closing Date may be selected by the Borrower during the term of this Agreement.  No Lender shall have any obligation to participate in any increase described in this paragraph unless it agrees to do so in its sole discretion.

(d) On each Increased Revolving Commitment Closing Date on which there are Revolving Loans outstanding, the New Lender(s) and/or Lender(s) that have increased their Revolving Commitments shall make Revolving Loans, the proceeds of which will be used to prepay the Revolving Loans of other Lenders, so that, after giving effect thereto, the resulting Revolving Loans outstanding are allocated among the Lenders in accordance with Section 2.11(a) based on the respective Revolving Percentages of the Lenders after giving effect to such Increased Revolving Commitment Closing Date.

(e) The Borrower shall repay the outstanding Revolving Loans of each Lender on the Revolving Termination Date applicable to such Lender.

2.2 Procedure for Revolving Loan Borrowing.   The Borrower may borrow under the Revolving Commitments during the Revolving Commitment Period on any Business Day, provided that the Borrower shall give the Administrative Agent irrevocable notice (which notice must be received by the Administrative Agent prior to 11:00 A.M., New York City time, (a) three Business Days prior to the requested Borrowing Date, in the case of Eurodollar Loans (or, with respect to any Eurodollar Loans to be made on the Closing Date, such shorter time period as may be agreed by the Administrative Agent) or (b) on the requested Borrowing Date, in the case of ABR Loans), specifying (i) the amount and Type of Revolving Loans to be borrowed, (ii) the requested Borrowing Date and (iii) in the case of Eurodollar Loans, the respective lengths of the initial Interest Period therefor.  Each borrowing under the Revolving Commitments shall be in an amount equal to (x) in the case of ABR Loans, $1,000,000 or a whole multiple thereof (or, if the then aggregate Available Revolving Commitments are less than $1,000,000, such lesser amount) and (y) in the case of Eurodollar Loans, $5,000,000 or a whole multiple of $1,000,000 in excess thereof.  Upon receipt of any such notice from the Borrower, the Administrative Agent shall promptly notify each Lender thereof.  Each Lender will make the amount of its pro rata share of each borrowing available to the Administrative Agent for the account of the Borrower at the Funding Office prior to 12:00 Noon, New York City time, on the Borrowing Date requested by the Borrower in funds immediately available to the Administrative Agent.  Such borrowing will then be made available to the Borrower by the Administrative Agent crediting the account of the Borrower on the books of such

(b)  Any Eurodollar Loan may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Borrower giving irrevocable notice to the Administrative Agent, in accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Revolving Loans, provided that no Eurodollar Loan may be continued as such when any Event of Default has occurred and is continuing and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such continuations, and provided, further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Revolving Loans shall be automatically converted to ABR Loans on the last day of such then expiring Interest Period.  Upon receipt of any such notice the Administrative Agent shall promptly notify each Lender thereof.

(a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

(b) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Revolving Loans during such Interest Period,

then (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as ABR Loans, (y) any Revolving Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as ABR Loans and (z) any outstanding Eurodollar Loans shall be converted, on the last day of the then-current Interest Period, to ABR Loans.  Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to convert Revolving Loans to Eurodollar Loans.

2.11 Pro Rata Treatment and Payments.  (a)   Except as otherwise expressly provided herein, each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee and any reduction of the Revolving Commitments of the Lenders shall be made pro rata according to the respective Revolving Percentages of the Lenders.

(b)  Except as otherwise expressly provided herein, each payment (including each prepayment) by the Borrower on account of principal of and interest on the Revolving Loans shall be made pro rata according to the respective outstanding principal amounts of the Revolving Loans then held by the Lenders.

(c)  All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in immediately available funds.  The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received.  If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day.  If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day.  In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.

(d)  Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount.  If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon, at a rate equal to the greater of (i) the Federal Funds Effective Rate and (ii) a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, for the period until such Lender makes such amount immediately available to the Administrative Agent.  A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the absence of manifest error.  If such Lender’s share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days after such Borrowing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to ABR Loans, on demand, from the Borrower.  Nothing herein shall be deemed to limit the rights of the Borrower against such Lender.

(e)  Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment due to be made by the Borrower hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective shares of a corresponding amount.  If such payment is not made to the Administrative Agent by the Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate.  Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrower.

2.12 Requirements of Law.  (a)   If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof:

(i)  shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any Application or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except, in each case, for Non-Excluded Taxes covered by Section 2.13 and changes in the rate of tax on the overall net income of such Lender);

(ii)  shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate; or

(iii)    shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender, by an amount that such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans or issuing or participating in Letters of Credit, or to reduce any amount receivable hereunder in respect

thereof, then, in any such case, the Borrower shall pay such Lender, reasonably promptly after its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable.  If any Lender becomes entitled to claim any additional amounts pursuant to this paragraph, it shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled, setting forth in reasonable detail the calculations upon which such Lender determined such amounts.

(b)  If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender’s or such corporation’s capital as a consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor setting forth in reasonable detail the calculations upon which such Lender determined such amounts, the Borrower shall pay to such Lender reasonably promptly after such submission such additional amount or amounts as will compensate such Lender or such corporation for such reduction.

(c)  A certificate as to any additional amounts payable pursuant to this Section submitted by any Lender to the Borrower (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error.  Notwithstanding anything to the contrary in this Section, the Borrower shall not be required to compensate a Lender pursuant to this Section for any amounts incurred more than six months prior to the date that such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor; provided that, if within such six-month period circumstances occur that give rise to such claim having a retroactive effect, then such six-month period shall be extended to include the period of such retroactive effect.  The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Revolving Loans and all other amounts payable hereunder.

2.13 Taxes.  (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on the Administrative Agent or any Lender as a result of a present or former connection between the Administrative Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document).  If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) or Other Taxes are required to be withheld from any amounts payable to the Administrative Agent or any Lender hereunder, the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement, provided, however, that the Borrower shall not be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes (i) that are attributable to such Lender’s failure to comply with the requirements of paragraph (d) or (e) of this

Section or (ii) that are United States withholding taxes imposed on amounts payable to such Lender at the time such Lender becomes a party to this Agreement, except to the extent that such Lender’s assignor (if any) was entitled, at the time of assignment, to receive such additional amounts from the Borrower with respect to such Non-Excluded Taxes pursuant to this paragraph, so long as such additional amounts payable by the Borrower are not increased thereby.

(b)  In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c)  Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for its own account or for the account of the relevant Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof or such other evidence of payment as is reasonably satisfactory to the Administrative Agent.  If the Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other documentary evidence, the Borrower shall indemnify the Administrative Agent and the Lenders for any incremental Non-Excluded Taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as a result of any such failure.

(d)   Each Lender (or Transferee) that is not a “U.S. Person” as defined in Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, a statement substantially in the form of Exhibit C and a Form W-8BEN, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan Documents.  Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation).  In addition, each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender.  Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose).  Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not legally able to deliver.

(e)  A Lender that is entitled to an exemption from or reduction of non-U.S. withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate, provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender’s judgment such completion, execution or submission would not materially prejudice the legal position of such Lender.

(f)  If the Administrative Agent or any Lender determines, in its sole discretion, that it has received a refund of any Non-Excluded Taxes or Other 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 2.13,

it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.13 with respect to the Non-Excluded Taxes or Other Taxes giving rise to such refund), net of all associated out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, shall repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This paragraph 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 which it deems confidential) to the Borrower or any other Person.

(g)  The agreements in this Section shall survive the termination of this Agreement and the payment of the Revolving Loans and all other amounts payable hereunder.

2.14 Indemnity.  The Borrower agrees to indemnify each Lender for, and to hold each Lender harmless from, any loss or expense that such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any prepayment of or conversion from Eurodollar Loans after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto.  Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Revolving Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market.  A certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error.  This covenant shall survive the termination of this Agreement and the payment of the Revolving Loans and all other amounts payable hereunder.

2.15 Change of Lending Office.  Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.12 or 2.13(a) with respect to such Lender, it will use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Revolving Loans affected by such event with the object of avoiding the consequences of such event; provided, that such designation is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this Section shall affect or postpone any of the obligations of the Borrower or the rights of any Lender pursuant to Section 2.12 or 2.13(a).

2.16 Replacement of Lenders.  The Borrower shall be permitted to replace any Lender that (a) requests reimbursement for amounts owing pursuant to Section 2.12 or 2.13(a), (b) defaults in its obligation to make Revolving Loans hereunder or (c) is a Non-Extending Lender, with a replacement financial institution or other entity; provided that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) in the case of clause (a) above, prior to any such replacement, such Lender shall have taken no action under Section 2.15 so as to eliminate the continued need for payment of amounts

owing pursuant to Section 2.12 or 2.13(a), (iv) the replacement financial institution shall purchase, at par, all Revolving Loans and other amounts owing to such replaced Lender on or prior to the date of replacement, (v) the Borrower shall be liable to such replaced Lender under Section 2.14 if any Eurodollar Loan owing to such replaced Lender shall be purchased other than on the last day of the Interest Period relating thereto, (vi) the replacement financial institution, if not already a Lender, shall be reasonably satisfactory to the Administrative Agent, (vii) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 10.6 (provided that the Borrower shall be obligated to pay the registration and processing fee referred to therein), (viii) until such time as such replacement shall be consummated, the Borrower shall pay all additional amounts (if any) required pursuant to Section 2.12 or 2.13(a), as the case may be, and (ix) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

2.17 Extension of Revolving Termination Date.  (a) The Borrower may, by written notice to the Administrative Agent in the form of Exhibit F-1 (the “Extension Request”) given no earlier than the first anniversary of the Closing Date but no later than 45 days prior to the then applicable Revolving Termination Date, request that the then applicable Revolving Termination Date be extended to the date that is one calendar year after the then applicable Revolving Termination Date.  Such extension shall be effective with respect to each Lender that, by a written notice in the form of Exhibit F-2 (a “Continuation Notice”) to the Administrative Agent given no later than 20 days prior to the then applicable Revolving Termination Date, consents, in its sole discretion, to such extension (each Lender giving a Continuation Notice being referred to herein as a “Continuing Lender” and each Lender other than a Continuing Lender being referred to herein as a “Non-Extending Lender”), provided that (i) such extension shall be effective only if the aggregate Revolving Commitments of the Continuing Lenders constitute at least 66-2/3% of the Total Revolving Commitments on the date of the Extension Request, (ii) any Lender that fails to submit a Continuation Notice at least 20 days prior to the then applicable Revolving Termination Date shall be deemed not to have consented to such extension and shall constitute a Non-Extending Lender and (iii) the Borrower may give only one Extension Request during the term of this Agreement.  No Lender shall have any obligation to consent to any extension of the Revolving Termination Date.  The Administrative Agent shall notify each Lender of the receipt of an Extension Request promptly after receipt thereof.  The Administrative Agent shall notify the Borrower and the Lenders no later than 15 days prior to the then applicable Revolving Termination Date whether the Administrative Agent has received Continuation Notices from Lenders holding Revolving Commitments aggregating at least 66-2/3% of the Total Revolving Commitments on the date of the Extension Request.

(b) The Revolving Commitment of each Non-Extending Lender shall terminate at the close of business on the Revolving Termination Date in effect prior to the delivery of such Extension Request without giving any effect to such proposed extension.  In accordance with Section 2.1(e), on such Revolving Termination Date, the Borrower shall pay to the Administrative Agent, for the account of each Non-Extending Lender, an amount equal to such Non-Extending Lender’s Revolving Loans, together with accrued but unpaid interest and fees thereon and all other amounts then payable hereunder to such Non-Extending Lender.  If, however, on or before the date which is 10 days prior to the Revolving Termination Date in effect prior to the delivery of an Extension Request pursuant to this Section 2.17, the Borrower obtains a replacement Lender pursuant to Section 2.16 for any such Non-Extending Lender and such replacement Lender agrees to the extension of the Revolving Termination Date pursuant to this Section 2.17, then such replacement Lender shall for all purposes of this Section 2.17 and this Agreement be deemed to be a Continuing Lender, and the Revolving Loans of such Lender shall not be due and payable pursuant to this Section 2.17(b).

SECTION 3.           LETTERS OF CREDIT

3.1           L/C Commitment.  (a) Subject to the terms and conditions hereof, each Issuing Lender, in reliance on the agreements of the other Lenders set forth in Section 3.4(a), agrees to issue Letters of Credit for the account of the Borrower on any Business Day during the Revolving Commitment Period in such form as may be approved from time to time by such Issuing Lender; provided that no Issuing Lender shall issue any Letter of Credit if, (i) after giving effect to such issuance, (A) the L/C Obligations would exceed the L/C Commitment or (B) the aggregate amount of the Available Revolving Commitments would be less than zero or (ii) such Issuing Lender shall have received written notice from the Administrative Agent or the Borrower, at least one Business Day prior to the requested date of issuance or amendment of the applicable Letter of Credit, that one or more applicable conditions contained in Section 5.2 shall not have been satisfied.  On the Closing Date, each Existing Letter of Credit shall be deemed to be a Letter of Credit issued hereunder for the account of the Borrower.  Each Letter of Credit shall (i) be denominated in Dollars and (ii) expire no later than the earlier of (x) the first anniversary of its date of issuance and (y) the date that is five Business Days prior to the Revolving Termination Date (as it may be extended), provided that any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (y) above).

(b)  No Issuing Lender shall at any time be obligated to issue any Letter of Credit if such issuance would conflict with, or cause such Issuing Lender or any L/C Participant to exceed any limits imposed by, any applicable Requirement of Law.

3.2           Procedure for Issuance of Letter of Credit.  The Borrower may from time to time request that an Issuing Lender issue a Letter of Credit by delivering to such Issuing Lender at its address set forth in its Issuing Lender Agreement an Application therefor, completed to the satisfaction of such Issuing Lender, and such other certificates, documents and other papers and information as such Issuing Lender may request.  Upon receipt of any Application, such Issuing Lender will process such Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby (but in no event shall an Issuing Lender be required to issue any Letter of Credit earlier than three Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed to by such Issuing Lender and the Borrower.  Such Issuing Lender shall furnish a copy of such Letter of Credit to the Borrower promptly following the issuance thereof.  The applicable Issuing Lender shall promptly furnish to the Administrative Agent, which shall in turn promptly furnish to the Lenders, notice of the issuance of each Letter of Credit (including the amount thereof).

3.3           Fees and Other Charges.  (a) The Borrower will pay a fee on all outstanding Letters of Credit at a per annum rate equal to the Applicable Margin then in effect with respect to Eurodollar Loans, shared ratably among the Lenders and payable quarterly in arrears on each Fee Payment Date after the issuance date.  In addition, the Borrower shall pay to the applicable Issuing Lender for its own account a fronting fee for each Letter of Credit requested by the Borrower in such amount and at such times as may be set forth in a separate letter agreement between the Borrower and such Issuing Lender (each, an “Issuing Lender Agreement”), which shall contain such Issuing Lender’s address for notices..

(b)   In addition to the foregoing fees, the Borrower shall pay or reimburse each Issuing Lender for such normal and customary costs and expenses as are incurred or charged by such Issuing

Lender in issuing, negotiating, effecting payment under, amending or otherwise administering any Letter of Credit.

3.4           L/C Participations.  (a)  Each Issuing Lender irrevocably agrees to grant and hereby grants to each L/C Participant, and, to induce such Issuing Lender to issue Letters of Credit, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from such Issuing Lender, on the terms and conditions set forth below, for such L/C Participant’s own account and risk an undivided interest equal to such L/C Participant’s Revolving Percentage in such Issuing Lender’s obligations and rights under and in respect of each Letter of Credit and the amount of each draft paid by such Issuing Lender thereunder.  Each L/C Participant agrees with each Issuing Lender that, if a draft is paid under any Letter of Credit for which such Issuing Lender is not reimbursed in full by the Borrower in accordance with the terms of this Agreement, such L/C Participant shall pay to such Issuing Lender upon demand at such Issuing Lender’s address for notices specified herein an amount equal to such L/C Participant’s Revolving Percentage of the amount of such draft, or any part thereof, that is not so reimbursed.  Each L/C Participant’s obligation to pay such amount shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such L/C Participant may have against such Issuing Lender, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence or continuance of a Default or an Event of Default or the failure to satisfy any of the other conditions specified in Section 5, (iii) any adverse change in the condition (financial or otherwise) of the Borrower, (iv) any breach of this Agreement or any other Loan Document by the Borrower or any other L/C Participant or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing

(b)  If any amount required to be paid by any L/C Participant to an Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any payment made by such Issuing Lender under any Letter of Credit is paid to such Issuing Lender within three Business Days after the date such payment is due, such L/C Participant shall pay to such Issuing Lender on demand an amount equal to the product of (i) such amount, times (ii) the daily average Federal Funds Effective Rate during the period from and including the date such payment is required to the date on which such payment is immediately available to such Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360.  If any such amount required to be paid by any L/C Participant pursuant to Section 3.4(a) is not made available to an Issuing Lender by such L/C Participant within three Business Days after the date such payment is due, such Issuing Lender shall be entitled to recover from such L/C Participant, on demand, such amount with interest thereon calculated from such due date at the rate per annum applicable to ABR Loans.  A certificate of an Issuing Lender submitted to any L/C Participant with respect to any amounts owing under this Section shall be conclusive in the absence of manifest error.

(c)  Whenever, at any time after an Issuing Lender has made payment under any Letter of Credit and has received from any L/C Participant its pro rata share of such payment in accordance with Section 3.4(a), such Issuing Lender receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of collateral applied thereto by such Issuing Lender), or any payment of interest on account thereof, such Issuing Lender will distribute to such L/C Participant its pro rata share thereof; provided, however, that in the event that any such payment received by an Issuing Lender shall be required to be returned by such Issuing Lender, such L/C Participant shall return to such Issuing Lender the portion thereof previously distributed by such Issuing Lender to it.

3.5           Reimbursement Obligation of the Borrower.  If any draft is paid under any Letter of Credit, the Borrower shall reimburse the applicable Issuing Lender for the amount of (a) the draft so paid and (b) any taxes, fees, charges or other costs or expenses incurred by such Issuing Lender in connection with such payment, not later than 12:00 Noon, New York City time, on (i) the Business Day

that the Borrower receives notice of such draft, if such notice is received on such day prior to 10:00 A.M., New York City time, or (ii) if clause (i) above does not apply, the Business Day immediately following the day that the Borrower receives such notice.  Each such payment shall be made to the applicable Issuing Lender at its address set forth in its Issuing Lender Agreement in Dollars and in immediately available funds.  Interest shall be payable on any such amounts from the date on which the relevant draft is paid until payment in full at the rate set forth in (x) until the Business Day next succeeding the date of the relevant notice, Section 2.8(b) and (y) thereafter, Section 2.8(c).

3.6           Obligations Absolute.  The Borrower’s obligations under this Section 3 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that the Borrower may have or have had against any Issuing Lender, any beneficiary of a Letter of Credit or any other Person.  The Borrower also agrees with each Issuing Lender that, absent gross negligence or willful misconduct of such Issuing Lender, such Issuing Lender shall not be responsible for, and the Borrower’s Reimbursement Obligations under Section 3.5 shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee.  No Issuing Lender shall be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions resulting from the gross negligence or willful misconduct of such Issuing Lender.  The Borrower agrees that any action taken or omitted by an Issuing Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct, shall be binding on the Borrower and shall not result in any liability of such Issuing Lender to the Borrower; provided that the Borrower shall not be precluded from asserting any claim for direct (but not consequential) damages suffered by the Borrower to the extent caused by (i) the gross negligence or willful misconduct of such Issuing Lender in determining whether a request presented under any Letter of Credit issued by it complied with the terms of such Letter of Credit or (ii) such Issuing Lender’s willful failure or gross negligence in failing to pay under any Letter of Credit issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit.

3.7           Letter of Credit Payments.  If any draft shall be presented for payment under any Letter of Credit, the applicable Issuing Lender shall promptly notify the Borrower of the date and amount thereof.  The responsibility of the applicable Issuing Lender to the Borrower in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are substantially in conformity with such Letter of Credit.

3.8           Applications.  To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this Section 3, the provisions of this Section 3 shall apply.

SECTION 4.           REPRESENTATIONS AND WARRANTIES

To induce the Administrative Agent and the Lenders to enter into this Agreement and to make the Revolving Loans and issue or participate in the Letters of Credit, the Borrower hereby represents and warrants to the Administrative Agent and each Lender that:

4.1           Financial Condition.  The audited consolidated balance sheet of the Borrower as at December 31, 2004, and the related consolidated statement of income and cash flows for the fiscal year then ended, reported on by and accompanied by an unqualified report from Deloitte & Touche LLP, present fairly the consolidated financial condition of the Borrower as of such date, and the consolidated results of its operations and its consolidated cash flows for the fiscal year then ended.  All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein).  Except as set forth on Schedule 4.1, neither the Borrower nor any Significant Subsidiary has any material Guarantee Obligations, contingent liabilities and liabilities for taxes, or any long-term leases or unusual forward or long-term commitments, including any interest rate or foreign currency swap or exchange transaction or other obligation in respect of derivatives, that are not reflected in the most recent financial statements referred to in this paragraph.

4.2           No Change.  Except as set forth on Schedule 4.2, since December 31, 2004, there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect.

4.3           Existence; Compliance with Law.  The Borrower and each Significant Subsidiary (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) has the power and authority, and the legal right, to own and operate its material properties, to lease the material properties it operates as lessee and to conduct the business in which it is currently engaged, (c) is duly qualified as a foreign corporation or other organization and in good standing under the laws of each jurisdiction where its ownership, lease or operation of property or the conduct of its business requires such qualification, except to the extent that the failure to be so qualified or in good standing could not, in the aggregate, reasonably be expected to have a Material Adverse Effect and (d) is in compliance with all Requirements of Law except to the extent that the failure to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect.

4.4           Power; Authorization; Enforceable Obligations.  The Borrower has the corporate power and authority to make, deliver and perform the Loan Documents to which it is a party and to obtain extensions of credit hereunder.  The Borrower has taken all necessary organizational action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and to authorize the extensions of credit on the terms and conditions of this Agreement.  No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with (a) any extension of credit hereunder when made (except for consents, authorizations, filings, notices or other acts required with respect to such extension of credit that have been obtained or made and are in full force and effect at the time of such extension of credit) or (b) the execution, delivery, performance, validity or enforceability of this Agreement or any of the Loan Documents.  Each Loan Document has been duly executed and delivered on behalf of the Borrower.  This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of the Borrower, enforceable against the Borrower in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

4.5           No Legal Bar.  The execution, delivery and performance of this Agreement and the other Loan Documents, the issuance of Letters of Credit, the borrowings hereunder and the use of the proceeds thereof will not (a) violate any (i) Requirement of Law or (ii) Contractual Obligation of the Borrower or any Significant Subsidiary (except in the case of this clause (a) to the extent any such violations could not, in the aggregate, reasonably be expected to have a Material Adverse Effect) and

(b) result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation.

4.6           Litigation.  Except as set forth on Schedule 4.6, no litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Borrower, threatened by or against the Borrower or any Significant Subsidiary or against any of their respective properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby, or (b) that could reasonably be expected to have a Material Adverse Effect.

4.7           Ownership of Property; Liens.  Except (i) for assets disposed of in the ordinary course of business since December 31, 2004 and (ii) as set forth on Schedule 4.7, on the Closing Date the Borrower and its Significant Subsidiaries have good title, free of all Liens other than Permitted Liens, to all of the material assets reflected in the Borrower’s consolidated balance sheet as of December 31, 2004 as owned by the Borrower and/or its Significant Subsidiaries.

4.8           Taxes.  Each of the Borrower and each Significant Subsidiary has filed or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all taxes shown to be due and payable on said returns or on any assessments made against it or any of its property and all other taxes, fees or other charges imposed on it or any of its property by any Governmental Authority (other than (i) those that are not in the aggregate material and (ii) any taxes, fees or other charges the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the Borrower or such Significant Subsidiary).

4.9           Federal Regulations.  No part of the proceeds of any Revolving Loans, and no other extensions of credit hereunder, will be used (a) for “buying” or “carrying” any “margin stock” within the respective meanings of each of the quoted terms under Regulation U as now and from time to time hereafter in effect for any purpose that violates the provisions of the Regulations of the Board or (b) for any purpose that violates the provisions of the Regulations of the Board.  If requested by any Lender or the Administrative Agent, the Borrower will furnish to the Administrative Agent and each Lender a statement to the foregoing effect in conformity with the requirements of FR Form G-3 or FR Form U-1, as applicable, referred to in Regulation U.

4.10         ERISA.  Except as could not reasonably be expected to have a Material Adverse Effect, (a) neither a Reportable Event nor an “accumulated funding deficiency” (within the meaning of Section 412 of the Code or Section 302 of ERISA), as applicable, has occurred during the five-year period prior to the date on which this representation is made or deemed made with respect to any Plan subject to Title IV of ERISA, Section 412 of the Code or Section 302 of ERISA, and each Plan has complied in all material respects with the applicable provisions of ERISA and the Code; (b) no termination of a Single Employer Plan has occurred, and no Lien on the assets of the Borrower or any Significant Subsidiary in favor of the PBGC or a Plan has arisen, during such five-year period; (c) the present value of all accrued benefits under each Single Employer Plan (based on those assumptions used to fund such Plans) did not, as of the last annual valuation date for which a valuation report is available prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Plan allocable to such accrued benefits by a material amount; and (d) neither the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a material liability under ERISA, and, to the knowledge of the Borrower or any Commonly Controlled Entity, neither the Borrower nor any Commonly Controlled Entity would become subject to any material liability under ERISA if the Borrower or any Commonly Controlled Entity were to withdraw completely from all Multiemployer

Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made.  Neither the Borrower nor any Commonly Controlled Entity has knowledge that any such Multiemployer Plan is in Reorganization or Insolvent.

4.12         Use of Proceeds.  The proceeds of the Revolving Loans and the Letters of Credit shall be used to effect the Refinancing, to pay fees and expenses incurred in connection therewith and for general corporate purposes (including commercial paper support).

4.13         Accuracy of Information, etc.  The information, taken as a whole, contained in this Agreement, the other Loan Documents, the Confidential Information Memorandum or the other documents, certificates or statements furnished by or on behalf of the Borrower to the Administrative Agent or the Lenders, or any of them, for use in connection with the transactions contemplated by this Agreement or the other Loan Documents, did not contain as of the date such information was so furnished (or, in the case of the Confidential Information Memorandum, together with all other information so furnished to the Lenders prior to the Closing Date, as of the date of this Agreement), any untrue statement of a material fact or omit to state a material fact necessary to make the information contained herein or therein not misleading in light of the circumstances under which such information was furnished.  The projections and pro forma financial information contained in the materials referenced above are based upon good faith estimates and assumptions believed by management of the Borrower to be reasonable at the time made, it being recognized by the Lenders that such financial information as it relates to future events is not to be viewed as fact and that actual results during the period or periods covered by such financial information may differ from the projected results set forth therein by a material amount.

4.14         Solvency.  The Borrower is, and after giving effect to the incurrence of all Indebtedness and obligations being incurred in connection herewith will be, Solvent.

(g)           (i) any Person shall engage in any non-exempt “prohibited transaction” (as defined in Section 406 of ERISA or Section 4975 of the Code) involving any Plan, (ii) any “accumulated funding deficiency” (as defined in Section 302 of ERISA), whether or not waived, shall exist with respect to any Plan subject to Section 412 of the Code or Section 302 of ERISA or any Lien in favor of the PBGC or a Plan shall arise on the assets of any Commonly Controlled Entity, (iii) a Reportable Event shall occur with respect to, or proceedings shall commence to have a trustee appointed, or a trustee shall be appointed, to administer or to terminate, any Single Employer Plan, which Reportable Event or commencement of proceedings or appointment of a trustee is, in the reasonable opinion of the Required Lenders, likely to result in the termination of such Plan for purposes of Title IV of ERISA, (iv) any Single Employer Plan shall terminate for purposes of Title IV of ERISA, (v) in connection with a withdrawal from, or the Insolvency or Reorganization of, a Multiemployer Plan, any Commonly Controlled Entity shall, or is reasonably likely to, incur any unpaid liability or (vi) any other similar event or condition shall occur or exist with respect to a Plan; and in each case in clauses (i) through (vi) above, such event or condition, together with all other such events or conditions, if any, could reasonably be expected to have a Material Adverse Effect; or

(h)           one or more judgments or decrees shall be entered against the Borrower or any Significant Subsidiary involving in the aggregate a liability (not paid or fully covered by insurance as to which the relevant insurance company has acknowledged coverage) of $50,000,000 or more, and such judgments or decrees shall not have been vacated, discharged, stayed or bonded pending appeal within 30 days from the entry thereof; or

(i)            a Change in Control shall occur;

then, and in any such event, (A) if such event is an Event of Default specified in paragraph (f) above, automatically the Revolving Commitments shall immediately terminate and the Revolving Loans (with accrued interest thereon) and all other amounts owing under this Agreement and the other Loan Documents shall immediately become due and payable, and (B) if such event is any other Event of Default, either or both of the following actions may be taken:  (i) with the consent of the Required Lenders, the Administrative Agent may, or upon the request of the Required Lenders, the Administrative Agent shall, by notice to the Borrower declare the Revolving Commitments to be terminated forthwith, whereupon the Revolving Commitments shall immediately terminate; and (ii) with the consent of the

Required Lenders, the Administrative Agent may, or upon the request of the Required Lenders, the Administrative Agent shall, by notice to the Borrower, declare the Revolving Loans (with accrued interest thereon) and all other amounts owing under this Agreement and the other Loan Documents to be due and payable forthwith, whereupon the same shall immediately become due and payable.  With respect to all Letters of Credit with respect to which presentment for honor shall not have occurred at the time of an acceleration pursuant to this paragraph, the Borrower shall at such time deposit in a cash collateral account opened by the Administrative Agent an amount equal to the aggregate then undrawn and unexpired amount of such Letters of Credit.  Amounts held in such cash collateral account shall be applied by the Administrative Agent to the payment of drafts drawn under such Letters of Credit.  During the continuance of an Event of Default, the Administrative Agent may, or upon the request of the Required Lenders shall, apply any Excess Balance (as defined below) to repay the Obligations.  If all Obligations (other than L/C Obligations in respect of undrawn Letters of Credit) have been paid in full, the Excess Balance shall be returned to the Borrower (or such other Person as may be lawfully entitled thereto).  If no Event of Default is then continuing, the Administrative Agent shall return to the Borrower the balance in the cash collateral account.  For purposes hereof, “Excess Balance” means the amount by which the balance in the cash collateral account exceeds the undrawn and unexpired amount of the Letters of Credit.  Except as expressly provided above in this Section, presentment, demand, protest and all other notices of any kind are hereby expressly waived by the Borrower.

SECTION 9.           THE AGENTS

9.1           Appointment.  Each Lender hereby irrevocably designates and appoints the Administrative Agent as the agent of such Lender under this Agreement and the other Loan Documents, and each such Lender irrevocably authorizes the Administrative Agent, in such capacity, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to the Administrative Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto.   Notwithstanding any provision to the contrary elsewhere in this Agreement, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent.

9.2           Delegation of Duties.  The Administrative Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties.  The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys in-fact selected by it with reasonable care.

9.3           Exculpatory Provisions.  Neither any Agent nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from its or such Person’s own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by the Borrower or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agents under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of the Borrower to perform its obligations hereunder or thereunder.  The Agents shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or

conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower.  Neither any Agent nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates shall, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as an Agent or any of its Affiliates in any capacity.

9.4           Reliance by Administrative Agent.  The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrower), independent accountants and other experts selected by the Administrative Agent.  The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless such Note had been assigned in accordance with the provisions of Section 10.6 hereof.  The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action.  The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Revolving Loans.

9.5           Notice of Default.  The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless the Administrative Agent has received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”.  In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give notice thereof to the Lenders.  The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders); provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders.

9.6           Non-Reliance on Agents and Other Lenders.  Each Lender expressly acknowledges that neither the Agents nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by any Agent hereafter taken, including any review of the affairs of the Borrower or any affiliate of the Borrower, shall be deemed to constitute any representation or warranty by any Agent to any Lender.  Each Lender represents to the Agents that it has, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Borrower and its affiliates and made its own decision to make its Revolving Loans hereunder and enter into this Agreement.  Each Lender also represents that it will, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrower and its affiliates.  Except for notices, reports and

other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower or any affiliate of the Borrower that may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates.

9.7           Indemnification.  The Lenders agree to indemnify each Agent in its capacity as such (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably according to their respective Aggregate Exposure Percentages in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Revolving Commitments shall have terminated and the Revolving Loans shall have been paid in full, ratably in accordance with such Aggregate Exposure Percentages immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Revolving Loans) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of, the Revolving Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from such Agent’s gross negligence or willful misconduct.  The agreements in this Section shall survive the payment of the Revolving Loans and all other amounts payable hereunder.

9.8           Agent in Its Individual Capacity.  Each Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower as though such Agent were not an Agent.  With respect to its Revolving Loans made or renewed by it and with respect to any Letter of Credit issued or participated in by it, each Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms “Lender” and “Lenders” shall include each Agent in its individual capacity.

9.9           Successor Administrative Agent.  The Administrative Agent may resign as Administrative Agent upon 10 days’ notice to the Lenders and the Borrower.  If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default under Section 8(a) or Section 8(f) with respect to the Borrower shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Revolving Loans.  If no successor agent has accepted appointment as Administrative Agent by the date that is 10 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above.  After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions of

this Section 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 and the other Loan Documents.

9.10         Documentation Agents and Syndication Agents.  Neither any Documentation Agent nor any Syndication Agent shall have any duties or responsibilities hereunder in its capacity as such.

SECTION 10.         MISCELLANEOUS

10.1         Amendments and Waivers.  Neither this Agreement, any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 10.1.  The Required Lenders and the Borrower may, or, with the written consent of the Required Lenders, the Administrative Agent and the Borrower may, from time to time, (a) enter into written amendments, supplements or modifications hereto and to the other Loan Documents for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or of the Borrower hereunder or thereunder or (b) waive, on such terms and conditions as the Required Lenders or the Administrative Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall (i) except as set forth in Section 2.17, forgive the principal amount or extend the final scheduled date of maturity of any Revolving Loan or Reimbursement Obligation, reduce the stated rate of any interest or fee payable hereunder (except in connection with the waiver of applicability of any post-default increase in interest rates (which waiver shall be effective with the consent of the Required Lenders)) or extend the scheduled date of any payment thereof, or increase the amount or extend the expiration date of any Lender’s Revolving Commitment, in each case without the written consent of each Lender directly affected thereby; (ii) eliminate or reduce the voting rights of any Lender under this Section 10.1 without the written consent of such Lender; (iii) reduce any percentage specified in the definition of Required Lenders or consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement and the other Loan Documents, in each case without the written consent of all Lenders; (iv) amend, modify or waive any provision of Section 2.11(a) or Section 2.11(b) without the written consent of each Lender directly affected thereby, (v) amend, modify or waive any provision of Section 9 without the written consent of the Administrative Agent; or (vi) amend, modify or waive any provision of Section 3 without the written consent of each Issuing Lender.  Notwithstanding anything contained in this Section 10.1, the affirmative vote of Lenders holding at least 66-2/3% of the Total Revolving Commitments then in effect (or, if the Revolving Commitments have been terminated, the Total Revolving Extensions of Credit then outstanding) shall be required to amend, modify or waive any provision of Section 2.17; provided that the Revolving Termination Date with respect to any Lender may not be extended with respect to such Lender without its written consent.  Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Borrower, the Lenders, the Administrative Agent and all future holders of the Revolving Loans.  In the case of any waiver, the Borrower, the Lenders and the Administrative Agent shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver, except to the extent expressly provided therein, shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon.

10.2         Notices.  All notices, requests and demands to or upon the respective parties hereto to be effective shall be in writing (including by electronic transmission or telecopy), and, unless otherwise expressly provided herein, shall be deemed to have been duly given or made when delivered, or three Business Days after being deposited in the mail, postage prepaid, or, in the case of telecopy notice, when received, addressed as follows in the case of the Borrower and the Administrative Agent, and as set

to notices pursuant to Section 2 unless otherwise agreed by the Administrative Agent and the applicable Lender.  The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications.

Information required to be delivered pursuant to Sections 6.1 and 6.2(b) shall be deemed to have been delivered on the date on which the Borrower provides notice to the Administrative Agent (which notice the Administrative Agent shall promptly provide to the Lenders)  that such information has been posted on the SEC website on the Internet at xxx.xxx/xxxxx/xxxxxxxx.xxx, on the Borrower’s IntraLinks site at xxxxxxxxxx.xxx or at another website identified in such notice and accessible by the Lenders without charge.

10.3         No Waiver; Cumulative Remedies.  No failure to exercise and no delay in exercising, on the part of the Administrative Agent or any Lender, any right, remedy, power or privilege hereunder or under the other Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.  The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

10.4         Survival of Representations and Warranties.  All representations and warranties made hereunder, in the other Loan Documents and in any document, certificate or statement delivered pursuant hereto or in connection herewith shall survive the execution and delivery of this Agreement and the making of the Revolving Loans and other extensions of credit hereunder.

10.5         Payment of Expenses and Taxes.  The Borrower agrees (a) to pay or reimburse the Administrative Agent for all its out-of-pocket costs and expenses incurred in connection with the development, preparation and execution of, and any amendment, supplement or modification to, this Agreement and the other Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including the reasonable fees and disbursements of counsel to the Administrative Agent and filing and recording fees and expenses, with statements with respect to the foregoing to be submitted to the Borrower prior to the Closing Date (in the case of amounts to be paid on the Closing Date) and from time to time thereafter on a quarterly basis or such other periodic basis as the Administrative Agent shall deem appropriate, (b) to pay or reimburse each Lender and the Administrative Agent for all its costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the other Loan Documents and any such other documents, including the reasonable fees and disbursements of counsel (including the allocated fees and expenses of in-house counsel) to each Lender and of counsel to the Administrative Agent, (c) to pay, indemnify, and hold each Lender and the Administrative Agent harmless from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, that may be payable or determined to be payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and (d) to pay, indemnify, and hold each Lender and the Administrative Agent and their respective officers, directors, employees, affiliates, agents and controlling persons (each, an “Indemnitee”) harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement, the other Loan Documents and any such other documents, including any of the foregoing relating to the use of proceeds of the Revolving Loans or the violation of, noncompliance with

or liability under, any Environmental Law applicable to the operations of the Borrower or any of its Subsidiaries or any of their properties and the reasonable fees and expenses of legal counsel in connection with claims, actions or proceedings by any Indemnitee against the Borrower under any Loan Document (all the foregoing in this clause (d), collectively, the “Indemnified Liabilities”), provided, that the Borrower shall have no obligation hereunder to any Indemnitee with respect to Indemnified Liabilities to the extent such Indemnified Liabilities resulted from the gross negligence or willful misconduct of such Indemnitee.  Without limiting the foregoing, and to the extent permitted by applicable law, the Borrower agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries to waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee, except to the extent that such claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses have resulted from the gross negligence or willful misconduct of such Indemnitee.  All amounts due under this Section 10.5 shall be payable not later than 10 days after written demand therefor.  Statements payable by the Borrower pursuant to this Section 10.5 shall be submitted to the Borrower at the address of the Borrower set forth in Section 10.2, or to such other Person or address as may be hereafter designated by the Borrower in a written notice to the Administrative Agent.  The agreements in this Section 10.5 shall survive repayment of the Revolving Loans and all other amounts payable hereunder.

10.6         Successors and Assigns; Participations and Assignments.  (a)  The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any affiliate of an Issuing Lender that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section.

(b)(i)  Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more financial institutions or other entities (each, an “Assignee”) all or a portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Commitments and the Revolving Loans at the time owing to it) with the prior written consent of:

(A) the Borrower (such consent not to be unreasonably withheld or delayed), provided that no consent of the Borrower shall be required for an assignment to a Lender or, if an Event of Default has occurred and is continuing, any other Person; and

(B) the Administrative Agent and each Issuing Lender.

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender or an affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Revolving Commitments or Revolving Loans, the amount of the Revolving Commitments or Revolving Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower, the Administrative Agent and each Issuing Lender otherwise consent, provided that (1) no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing and (2) such amounts shall be aggregated in respect of each Lender and its affiliates, if any;

(B) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

(C) the Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an administrative questionnaire.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) below, from and after the effective date specified in each Assignment and Assumption the Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.12, 2.13, 2.14 and 10.5 in respect of the period that it was a Lender).  Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 10.6 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv)  The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Revolving Commitments of, and principal amount of the Revolving Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”).  The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Lenders and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary.

(v)  Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an Assignee, the Assignee’s completed administrative questionnaire (unless the Assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register.  No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)(i)  Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Revolving Commitments and the Revolving Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, each Issuing Lender 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.  Any agreement pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that (1) requires the consent of such Lender pursuant to the proviso to the second sentence of Section 10.1 and (2) directly affects such Participant.  Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.12, 2.13 and 2.14 to the same extent as if it were a Lender and had

acquired its interest by assignment pursuant to paragraph (b) of this Section.  To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.7(b) as though it were a Lender, provided such Participant shall be subject to Section 10.7(a) as though it were a Lender.

(ii)  A Participant shall not be entitled to receive any greater payment under Section 2.12 or 2.13 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent.  In addition, any Participant that is a Non-U.S. Lender shall not be entitled to the benefits of Section 2.13 unless such Participant complies with Section 2.13(d).

(d)  Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations to a Federal Reserve Bank.

(e)  The Borrower, upon receipt of written notice from the relevant Lender, agrees to issue Notes to any Lender requiring Notes to facilitate transactions of the type described in paragraph (d) above.

10.7         Adjustments; Set-off.  (a)  Except to the extent that this Agreement expressly provides for payments to be allocated to a particular Lender, if any Lender (a “Benefitted Lender”) shall, at any time after the Revolving Loans and other amounts payable hereunder shall immediately become due and payable pursuant to Section 8, receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 8(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of the Obligations owing to such other Lender, such Benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of the Obligations owing to each such other Lender, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(b)  In addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency or Affiliate thereof to or for the credit or the account of the Borrower, as the case may be.  Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such setoff and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such setoff and application.

10.8         Counterparts.  This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument.  Delivery of an executed signature page of this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof.  A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent.

10.9         Severability.  Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

10.10       Integration.  This Agreement and the other Loan Documents represent the entire agreement of the Borrower, the Administrative Agent and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent or any Lender relative to the subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents.

10.11       GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

10.12       Submission To Jurisdiction; Waivers.  The Borrower hereby irrevocably and unconditionally:

(a)           submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States for the Southern District of New York, and appellate courts from any thereof;

(b)           consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c)           agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to the Borrower, as the case may be at its address set forth in Section 10.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto;

(d)           agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to xxx in any other jurisdiction; and

(e)           waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages.

10.13       Acknowledgements.  The Borrower hereby acknowledges that:

(a)           it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents;

(b)           neither the Administrative Agent nor any Lender has any fiduciary relationship with or duty to the Borrower arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between Administrative Agent and Lenders, on one hand,

and the Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c)           no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among the Borrower and the Lenders.

10.14       Confidentiality.  Each of the Administrative Agent and each Lender agrees to keep confidential all information provided to it by or on behalf of the Borrower, the Administrative Agent or any Lender pursuant to or in connection with this Agreement and to use such information solely in connection with evaluating, administering, structuring and/or approving the credit facility contemplated hereby; provided that nothing herein shall prevent the Administrative Agent or any Lender from disclosing any such information (a) to the Administrative Agent, any other Lender or any affiliate thereof, solely for the purpose of evaluating, administering, structuring and/or approving the credit facility contemplated hereby, (b) subject to an agreement to comply with the provisions of this Section, to any actual or prospective Transferee or any direct or indirect counterparty to any Swap Agreement (or any professional advisor to such counterparty), (c) to its employees, directors, agents, attorneys, accountants and other professional advisors or those of any of its affiliates, solely for the purpose of evaluating, administering, structuring and/or approving the credit facility contemplated hereby, (d) upon the request or demand of any Governmental Authority, (e) in response to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any Requirement of Law, (f) if requested or required to do so in connection with any litigation or similar proceeding, (g) that has been publicly disclosed, (h) to the National Association of Insurance Commissioners or any similar organization or any nationally recognized rating agency that requires access to information about a Lender’s investment portfolio in connection with ratings issued with respect to such Lender, or (i) in connection with the exercise of any remedy hereunder or under any other Loan Document.

10.15       WAIVERS OF JURY TRIAL.  THE BORROWER, THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

L. 107-56 (signed into law October 26, 2001)) (the “Act”), it 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 Act.
