(a)           Each Borrowing, each conversion of Loans from one Type to the other, and each continuation of Eurodollar Rate Loans or IBOR Rate Loans shall be made upon Borrower’s irrevocable notice to Agent, which may be given by telephone.  Each such notice must be received by Agent not later than 11:00 a.m. (i) three Business Days (in the case of Eurodollar Rate Loans) or one Business Day (in the case of IBOR Rate Loans) prior to the requested date of any Borrowing of, conversion to or continuation of Eurodollar Rate Loans or IBOR Rate Loans or of any conversion of Eurodollar Rate Loans or IBOR Rate Loans to Base Rate Loans, and (ii) on the requested date of any Borrowing of Base Rate Loans.  Borrower shall have the option to borrow or continue IBOR Rate Loans or convert Loans into IBOR Rate Loans only so long as Bank of America, N.A. is the sole Lender under this Agreement.  Each

24

telephonic notice by Borrower pursuant to this Section 2.2(a) must be confirmed promptly by delivery to Agent of a written Loan Notice, appropriately completed and signed by a Responsible Officer of Borrower.  Each Borrowing of, conversion to or continuation of Eurodollar Rate Loans or IBOR Rate Loans shall be in a principal amount of $2,000,000 or a whole multiple of $500,000 in excess thereof.  Except as provided in Sections 2.3(c) and 2.4(c), each Borrowing of or conversion to Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof.  Each Loan Notice (whether telephonic or written) shall specify (i) whether Borrower is requesting a Borrowing, a conversion of Loans from one Type to the other, or a continuation of Eurodollar Rate Loans or IBOR Rate Loans, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal amount of Loans to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or to which existing Loans are to be converted, and (v) if applicable, the duration of the Interest Period with respect thereto.  If Borrower fails to specify a Type of Loan in a Loan Notice or if Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Loans shall be made as, or converted to, Base Rate Loans.  Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Eurodollar Rate Loans or IBOR Rate Loans.  If Borrower requests a Borrowing of, conversion to, or continuation of Eurodollar Rate Loans or IBOR Rate Loans in any such Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month.

(b)           Following receipt of a Loan Notice, Agent shall promptly notify each Lender of the amount of its Pro Rata Share of the applicable Loans, and if no timely notice of a conversion or continuation is provided by Borrower, Agent shall notify each Lender of the details of any automatic conversion to Base Rate Loans described in the preceding subsection.  In the case of a Borrowing, each Lender shall make the amount of its Loan available to Agent in immediately available funds at Agent’s Office not later than 1:00 p.m. on the Business Day specified in the applicable Loan Notice.  Upon satisfaction of the applicable conditions set forth in Section 4.2 (and, if such Borrowing is the initial Credit Extension, Section 4.1), Agent shall make all funds so received available to Borrower in like funds as received by Agent either by (i) crediting the account of Borrower on the books of Bank of America with the amount of such funds or (ii) wire transfer of such funds, in each case in accordance with instructions provided to (and reasonably acceptable to) Agent by Borrower; provided, however, that if, on the date the Loan Notice with respect to such Borrowing is given by Borrower, there are L/C Borrowings outstanding, then the proceeds of such Borrowing first, shall be applied, to the payment in full of any such L/C Borrowings, and second, shall be made available to Borrower as provided above.

(c)           Except as otherwise provided herein, a Eurodollar Rate Loan or IBOR Rate Loan may be continued or converted only on the last day of an Interest Period for such Eurodollar Rate Loan or IBOR Rate Loan, as applicable.  During the existence of a Default, no Loans may be requested as, converted to or continued as Eurodollar Rate Loans or IBOR Rate Loans without the consent of the Required Lenders, and during the existence of an Event of Default, the Required Lenders may demand that any or all of the then outstanding Eurodollar Rate Loans or IBOR Rate Loans be converted immediately to Base Rate Loans and Borrower agrees to pay all amounts due under Section 3.5 in accordance with the terms thereof due to any such conversion.

25

(d)           Agent shall promptly notify Borrower and Lenders of the interest rate applicable to any Interest Period for Eurodollar Rate Loans or IBOR Rate Loans upon determination of such interest rate.  The determination of the Eurodollar Rate or the IBOR Rate by Agent shall be conclusive in the absence of manifest error.

(e)           After giving effect to all Borrowings, all conversions of Loans from one Type to the other, and all continuations of Loans as the same Type, there shall not be more than 6 Interest Periods in effect with respect to Loans.

2.3          Letters of Credit.

(a)           The Letter of Credit Commitment.

(i)            Subject to the terms and conditions set forth herein, (A) the L/C Issuer agrees, in reliance upon the agreements of the other Lenders set forth in this Section 2.3, (1) from time to time on any Business Day during the period from the Closing Date until the day that is thirty days prior to the Maturity Date, to issue Letters of Credit for the account of Borrower or its Subsidiaries, and to amend or extend Letters of Credit previously issued by it, in accordance with subsection (b) below, and (2) to honor drawings under the Letters of Credit; and (B) the Lenders severally agree to participate in Letters of Credit issued for the account of Borrower or its Subsidiaries and any drawings thereunder; provided that after giving effect to any L/C Credit Extension with respect to any Letter of Credit, (x) the Total Outstandings shall not exceed the Aggregate Commitments, (y) the aggregate Outstanding Amount of the Loans of any Lender, plus such Lender’s Pro Rata Share of the Outstanding Amount of all L/C Obligations shall not exceed such Lender’s Commitment, or (z) the Outstanding Amount of the L/C Obligations shall not exceed the L/C Sublimit.  Each request by Borrower for the issuance or amendment of a Letter of Credit shall be deemed to be a representation by Borrower that the L/C Credit Extension so requested complies with the conditions set forth in the proviso to the preceding sentence.  Within the foregoing limits, and subject to the terms and conditions hereof, Borrower’s ability to obtain Letters of Credit shall be fully revolving,  and accordingly Borrower may, during the foregoing period, obtain Letters of Credit to replace Letters of Credit that have expired or that have been drawn upon and reimbursed.

(ii)          The L/C Issuer shall not issue any Letter of Credit, if:

(A)          subject to Section 2.3(b)(iv), the expiry date of such requested commercial Letter of Credit would occur more than twelve months after the date of issuance or last extension or such standby Letter of Credit would occur more than twenty-four months after the date of issuance or last extension, unless the Required Lenders have approved such expiry date; or

26

(B)           the expiry date of such requested Letter of Credit would occur after the L/C Expiration Date, unless all the Lenders have approved such expiry date.

(C)           the expiry date of such requested Letter of Credit would occur after the Maturity Date, unless Borrower shall have Cash Collateralized 105% of the maximum aggregate L/C Obligations of such Letter of Credit.

(iii)          The L/C Issuer shall be under no obligation to issue any Letter of Credit if:

(A)          any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the L/C Issuer from issuing such Letter of Credit, or any Law applicable to the L/C Issuer or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the L/C Issuer shall prohibit, or request that the L/C Issuer refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon the L/C Issuer with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the L/C Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon the L/C Issuer any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which the L/C Issuer in good ▇▇▇▇▇ ▇▇▇▇▇ material to it;

(B)           the issuance of such Letter of Credit would violate any Laws or one or more policies of the L/C Issuer;

(C)           except as otherwise agreed by Agent and the L/C Issuer, such Letter of Credit is in an initial face amount less than $100,000, in the case of a commercial Letter of Credit, or $500,000, in the case of a standby Letter of Credit;

(D)          such Letter of Credit is to be denominated in a currency other than Dollars; or

(E)           a default of any Lender’s obligations to fund under Section 2.3(c) exists or any Lender is at such time a Defaulting Lender hereunder, unless the L/C Issuer has entered into satisfactory arrangements with Borrower or such Lender to eliminate the L/C Issuer’s risk with respect to such Lender; or

(F)           such Letter of Credit contains any provisions for automatic reinstatement of the stated amount after any drawing thereunder.

27

(iv)          The L/C Issuer shall not amend any Letter of Credit if the L/C Issuer would not be permitted at such time to issue such Letter of Credit in its amended form under the terms hereof.

(v)           The L/C Issuer shall be under no obligation to amend any Letter of Credit if (A) the L/C Issuer would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit does not accept the proposed amendment to such Letter of Credit.

(b)          Procedures for Issuance and Amendment of Letters of Credit; Extension of Letters of Credit.

(i)            Each Letter of Credit shall be issued or amended, as the case may be, upon the request of Borrower delivered to the L/C Issuer (with a copy to Agent) in the form of a L/C Application, appropriately completed and signed by a Responsible Officer of Borrower.  Such L/C Application must be received by the L/C Issuer and Agent not later than 11:00 a.m. at least two Business Days (or such later date and time as Agent and the L/C Issuer may agree in a particular instance in their sole discretion) prior to the proposed issuance date or date of amendment, as the case may be.  In the case of a request for an initial issuance of a Letter of Credit, such L/C Application shall specify in form and detail satisfactory to the L/C Issuer:  (A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G) such other matters as the L/C Issuer may require.  In the case of a request for an amendment of any outstanding Letter of Credit, such L/C Application shall specify in form and detail satisfactory to the L/C Issuer (A) the Letter of Credit to be amended; (B) the proposed date of amendment thereof (which shall be a Business Day); (C) the nature of the proposed amendment; and (D) such other matters as the L/C Issuer may require.  Additionally, Borrower shall furnish to the L/C Issuer and Agent such other documents and information pertaining to such requested Letter of Credit issuance or amendment, including any Issuer Documents, as the L/C Issuer or Agent may require.

(ii)           Promptly after receipt of any L/C Application at the address set forth in Section 10.2 for receiving L/C Applications and related correspondence, the L/C Issuer will confirm with Agent (by telephone or in writing) that Agent has received a copy of such L/C Application from Borrower and, if not, the L/C Issuer will provide Agent with a copy thereof.  Unless the L/C Issuer has received written notice from any Lender, Agent or any Loan Party, 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 in Article IV shall not then be satisfied, then, subject to the terms and conditions hereof, the L/C Issuer shall, on

28

the requested date, issue a Letter of Credit for the account of Borrower (or the applicable Subsidiary) or enter into the applicable amendment, as the case may be, in each case in accordance with the L/C Issuer’s usual and customary business practices.  Immediately upon the issuance of each Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the L/C Issuer a risk participation in such Letter of Credit in an amount equal to the product of such Lender’s Pro Rata Share times the amount of such Letter of Credit.

(iii)          Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, the L/C Issuer will also deliver to Borrower and Agent a true and complete copy of such Letter of Credit or amendment.

(iv)          If Borrower so requests in any applicable L/C Application, the L/C Issuer may, in its sole and absolute discretion, agree to issue a standby Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit the L/C Issuer to prevent any such extension at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such twelve-month period to be agreed upon at the time such Letter of Credit is issued.  Unless otherwise directed by the L/C Issuer, Borrower shall not be required to make a specific request to the L/C Issuer for any such extension.  Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the L/C Issuer to permit the extension of such Letter of Credit at any time to an expiry date not later than the day that is thirty days prior to the Maturity Date; provided, however, that the L/C Issuer shall not permit any such extension if (A) the L/C Issuer has determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of clause (ii) or (iii) of Section 2.3(a) or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is five Business Days before the Non-Extension Notice Date (1) from Agent that the Required Lenders have elected not to permit such extension or (2) from Agent, any Lender or any Loan Party that one or more of the applicable conditions specified in Section 4.2 is not then satisfied, and in each such case directing the L/C Issuer not to permit such extension.

(v)           If any Letter of Credit contains provisions providing for automatic reinstatement of the stated amount after any drawing thereunder, (A) unless otherwise directed by the L/C Issuer, Borrower shall not be required to make a specific request to the L/C Issuer to permit such reinstatement, and (B) Agent and the Lenders hereby authorize and direct the L/C Issuer to permit such automatic reinstatement, whether or not a Default then exists, unless the L/C Issuer has received a notice (which may be by telephone or in writing) on or before the day that is two Business Days before the reinstatement date from Agent, the Required

29

Lenders or any Loan Party that one or more of the applicable conditions specified in Section 4.2 is not then satisfied and directing the L/C Issuer to cease permitting such automatic reinstatement of such Letter of Credit.

(c)           Drawings and Reimbursements; Funding of Participations.

(i)            Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the L/C Issuer shall notify Borrower and Agent thereof.  Not later than 11:00 a.m. on the date of any payment by the L/C Issuer under a Letter of Credit (each such date, an “Honor Date”), Borrower shall reimburse the L/C Issuer through Agent in an amount equal to the amount of such drawing.  If Borrower fails to so reimburse the L/C Issuer by such time, Agent shall promptly notify each Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Lender’s Pro Rata Share thereof.  In such event, Borrower shall be deemed to have requested a Borrowing of Base Rate Loans to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.2 for the principal amount of Base Rate Loans, but subject to the amount of the unutilized portion of the Aggregate Commitments and the conditions set forth in Section 4.2 (other than the delivery of a Loan Notice).  Any notice given by the L/C Issuer or Agent pursuant to this Section 2.3(c)(i) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii)           Each Lender (including Lender acting as L/C Issuer) shall upon any notice pursuant to Section 2.3(c)(i) make funds available to Agent for the account of the L/C Issuer at the Agent’s Office in an amount equal to its Pro Rata Share of the Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by Agent, whereupon, subject to the provisions of Section 2.3(c)(iii), each Lender that so makes funds available shall be deemed to have made a Base Rate Loan to Borrower in such amount.  Agent shall remit the funds so received to the L/C Issuer.

(iii)          With respect to any Unreimbursed Amount that is not fully refinanced by a Borrowing of Base Rate Loans because the conditions set forth in Section 4.2 cannot be satisfied or for any other reason, Borrower shall be deemed to have incurred from the L/C Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the Default Rate.  In such event, each Lender’s payment to Agent for the account of the L/C Issuer pursuant to Section 2.3(c)(ii) shall be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.3.

30

(iv)          Until each Lender funds its Loan or L/C Advance pursuant to this Section 2.3(c) to reimburse the L/C Issuer for any amount drawn under any Letter of Credit, interest in respect of such Lender’s Pro Rata Share of such amount shall be solely for the account of the L/C Issuer.

(v)           Each Lender’s obligation to make Loans or L/C Advances to reimburse the L/C Issuer for amounts drawn under Letters of Credit, as contemplated by this Section 2.3(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the L/C Issuer, Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Loans pursuant to this Section 2.3(c) is subject to the conditions set forth in Section 4.2 (other than delivery by Borrower of a Loan Notice).  No such making of an L/C Advance shall relieve or otherwise impair the obligation of Borrower to reimburse the L/C Issuer for the amount of any payment made by the L/C Issuer under any Letter of Credit, together with interest as provided herein.

(vi)          If any Lender fails to make available to Agent for the account of the L/C Issuer any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.3(c) by the time specified in Section 2.3(c)(ii), the L/C Issuer shall be entitled to recover from such Lender (acting through Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the L/C Issuer at a rate per annum equal to the Federal Funds Rate from time to time in effect.  A certificate of the L/C Issuer submitted to any Lender (through Agent) with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error.

(d)          Repayment of Participations.

(i)            At any time after the L/C Issuer has made a payment under any Letter of Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.3(c), if Agent receives for the account of the L/C Issuer any payment in respect of the related Unreimbursed Amount or interest thereon (whether directly from Borrower or otherwise, including proceeds of Cash Collateral applied thereto by Agent), Agent will distribute to such Lender its Pro Rata Share thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s L/C Advance was outstanding) in the same funds as those received by Agent.

(ii)           If any payment received by Agent for the account of the L/C Issuer pursuant to Section 2.3(c)(i) is required to be returned under any of the circumstances described in Section 10.6 (including pursuant to any settlement entered into by the L/C Issuer in its discretion), each Lender shall pay to Agent

31

for the account of the L/C Issuer its Pro Rata Share thereof on demand of Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect.

(e)           Obligations Absolute.  The obligation of Borrower to reimburse the L/C Issuer for each drawing under each Letter of Credit and to repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

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

(ii)           the existence of any claim, counterclaim, set-off, defense or other right that Borrower or any Subsidiary may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the L/C Issuer or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

(iii)          any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

(iv)          any payment by the L/C Issuer under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by the L/C Issuer under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law; or

(v)           any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, Borrower or any Subsidiary.

Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with Borrower’s instructions or other irregularity, Borrower will immediately notify the L/C Issuer.  Borrower shall be conclusively deemed to have waived any such claim against the L/C Issuer and its correspondents unless such notice is given as aforesaid.

32

(f)            Role of L/C Issuer.  Each Lender and Borrower agree that, in paying any drawing under a Letter of Credit, the L/C Issuer shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document.  None of the L/C Issuer, any Agent-Related Person nor any of the respective correspondents, participants or assignees of the L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of Lenders or the Required Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or L/C Application.  Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement.  None of the L/C Issuer, any Agent-Related Person, nor any of the respective correspondents, participants or assignees of the L/C Issuer, shall be liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.3(e); provided, however, that anything in such clauses to the contrary notwithstanding, Borrower may have a claim against the L/C Issuer, and the L/C Issuer may be liable to Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by Borrower which Borrower proves were caused by the L/C Issuer’s willful misconduct or gross negligence or the L/C Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit.  In furtherance and not in limitation of the foregoing, the L/C Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and the L/C Issuer shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

(g)           Cash Collateral.  Upon the request of Agent, (i) if the L/C Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing, or (ii) if, as of the day that is thirty days prior to the Maturity Date, any Letter of Credit for any reason remains outstanding and partially or wholly undrawn, Borrower shall immediately Cash Collateralize the then Outstanding Amount of all L/C Obligations (in an amount equal to such Outstanding Amount determined as of the date of such L/C Borrowing or the day that is thirty days prior to the Maturity Date, as the case may be).  Sections 2.3(a), 2.5 and 8.2(c) set forth certain additional requirements to deliver Cash Collateral hereunder.  For purposes hereof, “Cash Collateralize” means to pledge and deposit with or deliver to Agent, for the benefit of the L/C Issuer and the Lenders, as collateral for the L/C Obligations, cash or deposit account balances pursuant to documentation in form and substance satisfactory to Agent and the L/C Issuer (which documents are hereby consented to by Lenders).  Derivatives of such term have corresponding meanings.  Borrower hereby grants to Agent, for the benefit of the L/C Issuer and Lenders, a security interest in all such cash, deposit accounts and all balances therein and all proceeds of the foregoing.  Cash collateral shall be maintained in blocked, non-interest bearing deposit accounts at Bank of America.

33

(h)           Applicability of ISP98 and UCP.  Unless otherwise expressly agreed by the L/C Issuer and Borrower when a Letter of Credit is issued, (i) the rules of the ISP shall apply to each standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce (the “ICC”) at the time of issuance shall apply to each commercial Letter of Credit.

(i)            L/C Fees.  Borrower shall pay to Agent for the account of each Lender in accordance with its Pro Rata Share an L/C fee (the “L/C Fee”) (i) for each commercial Letter of Credit equal to the then applicable commercial letter of credit fees of the L/C Issuer then in effect, and (ii) for each standby Letter of Credit equal to the Applicable Rate times the daily maximum amount available to be drawn under such Letter of Credit (whether or not such maximum amount is then in effect under such Letter of Credit).  L/C Fees shall be (i) computed on a quarterly basis in arrears and (ii) due and payable on the first Business Day after the end of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, on the L/C Expiration Date and thereafter on demand.  If there is any change in the Applicable Rate during any quarter, the daily maximum amount of each standby Letter of Credit shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect.  Notwithstanding anything to the contrary contained herein, upon the request of the Required Lenders, while any Event of Default exists, all L/C Fees shall accrue at the Default Rate.

(j)            Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer.  During the time that there are two or more Lenders party to this Agreement, Borrower shall pay directly to the L/C Issuer for its own account a fronting fee with respect to each Letter of Credit in the amounts equal to 1/8 of 1% per annum, payable on the actual daily maximum amount available to be drawn under such Letter of Credit (whether or not such maximum amount is then in effect under such Letter of Credit).  Such fronting fee shall be due and payable on the first Business Day after the end of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, on the L/C Expiration Date and thereafter on demand.  In addition, without regard to the number of Lenders party to this Agreement, Borrower shall pay directly to the L/C Issuer for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of the L/C Issuer relating to letters of credit as from time to time in effect.  Such individual customary fees and standard costs and charges are due and payable on demand and are nonrefundable.

(k)           Conflict with Issuer Documents.  In the event of any conflict between the terms hereof and the terms of any Issuer Documents, the terms hereof shall control.

(l)            Letters of Credit Issued for Subsidiaries.  Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary, Borrower shall be obligated to reimburse the L/C Issuer hereunder for any and all drawings under such Letter of Credit.  Borrower hereby acknowledges that the issuance of Letters of Credit for the account of Subsidiaries inures to the benefit of Borrower, and that Borrower’s business derives substantial benefits from the businesses of such Subsidiaries.

(a)           Voluntary Prepayments.  Borrower may, upon notice to Agent, at any time or from time to time voluntarily prepay Loans in whole or in part without premium or penalty; but with accrued interest thereon and any amounts due under Section 3.5, provided that (i) such notice must be received by Agent not later than 11:00 a.m. (A) three Business Days prior to any date of prepayment of Eurodollar Rate Loans or IBOR Rate Loans and (B) on the date of prepayment of Base Rate Loans; (ii) any prepayment of Eurodollar Rate Loans or IBOR Rate Loans shall be in a principal amount of $2,000,000 or a whole multiple of $500,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if less, the entire principal amount thereof then outstanding.  Each such notice shall specify the date and amount of such prepayment and the Type(s) of Loans to be prepaid.  Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s Pro Rata Share of such prepayment.  If such notice is given by Borrower, Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein.  Any prepayment of a Eurodollar Rate Loan or IBOR Rate Loan shall be accompanied by all accrued interest thereon, together with any additional amounts required pursuant to Section 3.5.  Each such prepayment shall be applied to the Loans of Lenders in accordance with their respective Pro Rata Shares.

(b)           Intentionally Deleted.

(c)           Mandatory Prepayments from Excess Utilization.  If for any reason the Total Outstandings at any time exceed the Aggregate Commitments then in effect, Borrower shall immediately prepay Loans but with accrued interest thereon and any amounts due under Section 3.5, and/or Cash Collateralize the L/C Obligations in an aggregate amount equal to such excess; provided, however, that Borrower shall not be required to Cash Collateralize the L/C Obligations pursuant to this Section 2.5(c) unless after the prepayment in full of the Loans the Total Outstandings exceed the Aggregate Commitments then in effect.

(d)           Mandatory Prepayments and Mandatory Reductions of Commitments.  The Loans shall be prepaid and/or the Aggregate Commitments shall be permanently reduced in the amounts and under the circumstances set forth below, and all such prepayments and/or reductions to be applied as set forth below or as more specifically provided in Section 2.5(e)(ii):

(i)            Mandatory Prepayments and Reductions From Net Asset Sale Proceeds.  No later than the date of receipt by Borrower or any of its Subsidiaries of any Net Asset Sale Proceeds in respect of any Asset Sale, Borrower shall either (1) prepay Loans and/or permanently reduce the Aggregate Commitments in accordance with Section 2.5(e)(ii), in each case, in an aggregate amount equal to such Net Asset Sale Proceeds or (2), so long as no Default or Event of Default shall have occurred and be continuing and to the extent that the aggregate Net Asset Sale Proceeds from the Closing Date through the date of determination that are so reinvested or proposed to be so reinvested under this Section 2.5(d)(i) (together with the aggregate Net Insurance/Condemnation Proceeds similarly applied from the Closing Date through the date of determination under

35

Section 2.5(d)(ii) or Section 6.6(b)(ii)) do not exceed $1,500,000, deliver to Agent an officer’s certificate setting forth (x) that portion of such Net Asset Sale Proceeds that Borrower or such Subsidiary intends to reinvest in equipment or other productive assets of the general type used in the business of Borrower and its Subsidiaries within 180 days of such date of receipt and (y) the proposed use of such portion of the Net Asset Sale Proceeds and such other information with respect to such reinvestment as Agent may reasonably request, and Borrower shall, or shall cause one or more of its Subsidiaries to, promptly and diligently apply such portion to such reinvestment purposes; provided, however, that, pending such reinvestment, such portion of the Net Asset Sale Proceeds shall be applied to prepay outstanding Loans (without a reduction in the Aggregate Commitments) to the full extent thereof.  In addition, Borrower shall, no later than 180 days after receipt of such Net Asset Sale Proceeds that have not theretofore been applied to the Obligations hereunder or that have not been so reinvested as provided above, make an additional prepayment of the Loans (and/or the Aggregate Commitments shall be permanently reduced) as set forth above in the full amount of all such Net Asset Sale Proceeds.

(ii)           Prepayments and Reductions from Net Insurance/Condemnation Proceeds.  No later than three (3) Business Days following the date of receipt by Agent, Borrower or any of its Subsidiaries of any Net Insurance/Condemnation Proceeds that are required to be applied to prepay the Loans and/or reduce the Aggregate Commitments pursuant to Section 6.6(b), Borrower shall either (1) prepay Loans and/or permanently reduce the Aggregate Commitments in accordance with Section 2.5(e)(ii), in each case, in an aggregate amount equal to such Net Insurance/Condemnation Proceeds or (2), so long as no Default or Event of Default shall have occurred and be continuing and to the extent that the aggregate Net Insurance/Condemnation Proceeds from the Closing Date through the date of determination that are so reinvested or proposed to be so reinvested under this Section 2.5(d)(ii) or under Section 6.6(b)(ii) (together with the aggregate Net Asset Sale Proceeds similarly applied from the Closing Date through the date of determination under Section 2.5(d)(i)) do not exceed $1,500,000, deliver to Agent an officer’s certificate setting forth (x) that portion of such Net Insurance/Condemnation Proceeds that Borrower or such Subsidiary intends to reinvest in equipment or other productive assets of the general type used in the business of Borrower and its Subsidiaries within 180 days of such date of receipt and (y) the proposed use of such portion of the Net Insurance/Condemnation Proceeds and such other information with respect to such reinvestment as Agent may reasonably request, and Borrower shall, or shall cause one or more of its Subsidiaries to, promptly and diligently apply such portion to such reinvestment purposes; provided, however, that, pending such reinvestment, such portion of the Net Insurance/Condemnation Proceeds shall be applied to prepay outstanding Loans (without a reduction in the Aggregate Commitments) to the full extent thereof.  In addition, Borrower shall, no later than 180 days after receipt of such Net Insurance/Condemnation Proceeds that have not theretofore been applied to the Obligations hereunder or that have not been so reinvested as provided above, make an additional prepayment of the Loans

36

(and/or the Aggregate Commitments shall be permanently reduced) as set forth above in the full amount of all such Net Insurance/Condemnation Proceeds.

(e)           Application of Prepayments and Reductions of Aggregate Commitments.

(i)            Application of Voluntary Prepayments by Type of Loans.  Any voluntary prepayments pursuant to Section 2.5(a) shall be applied as specified by Borrower in the applicable notice of prepayment; provided that in the event Borrower fails to specify the Type of Loans to which any such prepayment shall be applied, such prepayment shall be applied to repay Base Rate Loans to the full extent thereof before application to Eurodollar Rate Loans and IBOR Rate Loans, in each case in a manner that minimizes the amount of any payment required to be made by Borrower pursuant to Section 3.5.

(ii)           Application of Mandatory Prepayments by Type of Loans.  Except as provided in Section 2.5(c), any amount required to be applied as a mandatory prepayment of the Loans and/or a reduction of the Aggregate Commitments shall be applied first to prepay the Loans to the full extent thereof and to permanently reduce the Aggregate Commitments by the amount of such prepayment, and second, to the extent of any remaining portion of such amount, to further permanently reduce the Aggregate Commitments to the full extent thereof.  Any mandatory prepayments pursuant to this Section 2.5 shall be applied as specified by Borrower in written notice to Agent; provided that in the event Borrower fails to specify the Type of Loan to which any such prepayment shall be applied, such prepayment shall be applied to repay Base Rate Loans to the full extent thereof before application to Eurodollar Rate Loans and IBOR Rate Loans, in each case in a manner that minimizes the amount of any payment required to be made by Borrower pursuant to Section 3.5.  Any mandatory reduction of the Aggregate Commitments pursuant to this Section 2.5(e) shall be in proportion to each Lender’s Pro Rata Share.

2.6          Termination or Reduction of Commitments.  Borrower may, upon notice to Agent, terminate the Aggregate Commitments, or from time to time permanently reduce the Aggregate Commitments; provided that (i) any such notice shall be received by Agent not later than 11:00 a.m. five Business Days prior to the date of termination or reduction, (ii) any such partial reduction shall be in an aggregate amount of $5,000,000 or any whole multiple of $1,000,000 in excess thereof, (iii) Borrower shall not terminate or reduce the Aggregate Commitments if, after giving effect thereto and to any concurrent prepayments hereunder, the Total Outstandings would exceed the Aggregate Commitments, and (iv) if, after giving effect to any reduction of the Aggregate Commitments, the L/C Sublimit exceeds the amount of the Aggregate Commitments, such Sublimit shall be automatically reduced by the amount of such excess.  Agent will promptly notify the Lenders of any such notice of termination or reduction of the Aggregate Commitments.  Any reduction of the Aggregate Commitments shall be applied to the Commitment of each Lender according to its Pro Rata Share.  All fees accrued until the effective date of any termination of the Aggregate Commitments shall be paid on the effective date of such termination.

37

2.7          Repayment of Loans.  Borrower shall repay to Lenders on the Maturity Date the aggregate principal amount of Loans outstanding on such date.

2.8          Interest.

(a)           Subject to the provisions of subsection (b) below, (i) each Eurodollar Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Eurodollar Rate for such Interest Period plus the Applicable Rate; (ii) each IBOR Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the IBOR Rate for such Interest Period plus the Applicable Rate and (iii) each Base Rate Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate.

(b)           (i)            If any amount of principal of any Loan is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(ii)           If any amount (other than principal of any Loan) payable by Borrower under any Loan Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then upon the request of the Required Lenders, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(iii)          Upon the request of the Required Lenders, while any Event of Default exists, Borrower shall pay interest on the principal amount of all outstanding Obligations hereunder at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(iv)          Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

(c)           Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein.  Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law.

2.9          Fees.  In addition to certain fees described in subsections (i) and (j) of Section 2.3:

(a)           Commitment Fee.  Borrower shall pay to Agent for the account of each Lender in accordance with its Pro Rata Share, a commitment fee equal to the Applicable Rate times the actual daily amount by which the Aggregate Commitments exceed the sum of (i) the Outstanding Amount of Loans and (ii) the Outstanding Amount of L/C Obligations.  The commitment fee shall accrue at all times during the Availability Period, including at any time

38

during which one or more of the conditions in Article IV is not met, and shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the Closing Date, and on the Maturity Date.  The commitment fee shall be calculated quarterly in arrears, and if there is any change in the Applicable Rate during any quarter, the actual daily amount shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect.

(b)           Agent’s Fees.  Borrower shall pay to Agent for Agent’s own account, fees in the amounts and at the times specified in the letter agreement, dated as of January 31, 2005 (the “Agent Fee Letter”), between Borrower and Agent.  Such fees shall be fully earned when paid and shall be nonrefundable for any reason whatsoever.

2.10        Computation of Interest and Fees.  All computations of interest for Base Rate Loans when the Base Rate is determined by Bank of America’s “prime rate” shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed.  All other computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year).  Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall, subject to Section 2.12(a), bear interest for one day.

2.11        Evidence of Debt.

(a)           The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by Agent in the ordinary course of business.  The accounts or records maintained by Agent and each Lender shall be conclusive absent manifest error of the amount of the Credit Extensions made by Lenders to Borrower and the interest and payments thereon.  Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of Borrower hereunder to pay any amount owing with respect to the Obligations.  In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of Agent in respect of such matters, the accounts and records of Agent shall control in the absence of manifest error.  Upon the request of any Lender made through Agent, Borrower shall execute and deliver to such Lender (through Agent) a Note, which shall evidence such Lender’s Loans in addition to such accounts or records.  Each Lender may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of its Loans and payments with respect thereto.

(b)           In addition to the accounts and records referred to in subsection (a), each Lender and Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit.  In the event of any conflict between the accounts and records maintained by Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of Agent shall control in the absence of manifest error.

39

2.12        Payments Generally.

(a)(i)        All payments to be made by Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff.  Except as otherwise expressly provided herein, all payments by Borrower hereunder shall be made to Agent, for the account of the respective Lenders to which such payment is owed, at the Agent’s Office in Dollars and in immediately available funds not later than 12:00 noon on the date specified herein.  Agent will promptly distribute to each Lender its Pro Rata Share (or other applicable share as provided herein) of such payment in like funds as received by wire transfer to such Lender’s Lending Office.  All payments received by Agent after 12:00 noon shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue.

(a)(ii)On each date when the payment of any principal, interest or fees are due hereunder or under any Note, Borrower agrees to maintain on deposit in an ordinary checking account maintained by Borrower with Agent (as such account shall be designated by Borrower in a written notice to Agent from time to time, the “Borrower Account”) an amount sufficient to pay such principal, interest or fees in full on such date.  Borrower hereby authorizes Agent (A) to deduct automatically all principal, interest or fees when due hereunder or under any Note from the Borrower Account, and (B) if and to the extent any payment of principal, interest or fees under this Agreement or any Note is not made when due to deduct any such amount from any or all of the accounts of Borrower maintained at Agent.  Agent agrees to provide written notice to Borrower of any automatic deduction made pursuant to this Section 2.12(a)(ii) showing in reasonable detail the amounts of such deduction.  Lenders agree to reimburse Borrower based on their Pro Rata Share for any amounts deducted from such accounts in excess of amount due hereunder and under any other Loan Documents.

(a)           If any payment to be made by Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be.

(b)           Unless Borrower or any Lender has notified Agent, prior to the date any payment is required to be made by it to Agent hereunder, that Borrower or such Lender, as the case may be, will not make such payment, Agent may assume that Borrower or such Lender, as the case may be, has timely made such payment and may (but shall not be so required to), in reliance thereon, make available a corresponding amount to the Person entitled thereto.  If and to the extent that such payment was not in fact made to Agent in immediately available funds, then:

(i)            if Borrower failed to make such payment, each Lender shall forthwith on demand repay to Agent the portion of such assumed payment that was made available to such Lender in immediately available funds, together with interest thereon in respect of each day from and including the date such amount was made available by Agent to such Lender to the date such amount is repaid to Agent in immediately available funds at the Federal Funds Rate from time to time in effect; and

(ii)           if any Lender failed to make such payment, such Lender shall forthwith on demand pay to Agent the amount thereof in immediately available funds, together with interest thereon for the period from the date such amount was made available by Agent to Borrower to the date such amount is recovered by

40

Agent (the “Compensation Period”) at a rate per annum equal to the Federal Funds Rate from time to time in effect. If such Lender pays such amount to Agent, then such amount shall constitute such Lender’s Loan included in the applicable Borrowing.  If such Lender does not pay such amount forthwith upon Agent’s demand therefor, Agent may make a demand therefor upon Borrower, and Borrower shall pay such amount to Agent, together with interest thereon for the Compensation Period at a rate per annum equal to the rate of interest applicable to the applicable Borrowing.  Nothing herein shall be deemed to relieve any Lender from its obligation to fulfill its Commitment or to prejudice any rights which Agent or Borrower may have against any Lender as a result of any default by such Lender hereunder.

A notice of Agent to any Lender or Borrower with respect to any amount owing under this subsection (c) shall be conclusive, absent manifest error.

(c)           If any Lender makes available to Agent funds for any Loan to be made by such Lender as provided in the foregoing provisions of this Article II, and such funds are not made available to Borrower by Agent because the conditions to the applicable Credit Extension set forth in Article IV are not satisfied or waived in accordance with the terms hereof, Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

(d)           The obligations of the Lenders hereunder to make Loans and to fund participations in Letters of Credit are several and not joint.  The failure of any Lender to make any Loan or to fund any such participation on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan or purchase its participation.

(e)           Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner.

2.13        Sharing of Payments.  If, other than as expressly provided elsewhere herein, any Lender shall obtain on account of the Loans made by it, or the participations in L/C Obligations held by it, any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) in excess of its ratable share (or other share contemplated hereunder) thereof, such Lender shall immediately (a) notify Agent of such fact, and (b) purchase from the other Lenders such participations in the Loans made by them and/or such subparticipations in the participations in L/C Obligations held by them, as the case may be, as shall be necessary to cause such purchasing Lender to share the excess payment in respect of such Loans or such participations, as the case may be, pro rata with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender under any of the circumstances described in Section 10.6 (including pursuant to any settlement entered into by the purchasing Lender in its discretion), such purchase shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying Lender’s required repayment to (ii) the total amount so

41

recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered, without further interest thereon.  Borrower agrees that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off, but subject to Section 10.9) with respect to such participation as fully as if such Lender were the direct creditor of Borrower in the amount of such participation.  Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this Section and will in each case notify the Lenders following any such purchases or repayments.  Each Lender that purchases a participation pursuant to this Section shall from and after such purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased.

ARTICLE III.        TAXES, YIELD PROTECTION AND ILLEGALITY

3.1          Taxes.

(a)           Any and all payments by Borrower to or for the account of Agent or any Lender under any Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and all liabilities with respect thereto, excluding, in the case of Agent and each Lender, taxes imposed on or measured by its overall net income, and franchise taxes imposed on it (in lieu of net income taxes), by the jurisdiction (or any political subdivision thereof) under the Laws of which Agent or such Lender, as the case may be, is organized or maintains a lending office (all such non-excluded taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and liabilities being hereinafter referred to as “Taxes”).  If Borrower shall be required by any Laws to deduct any Taxes from or in respect of any sum payable under any Loan Document to Agent or any Lender, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section), each of Agent and such Lender receives an amount equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make such deductions, (iii) Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Laws, and (iv) within 30 days after the date of such payment, Borrower shall furnish to Agent (which shall forward the same to such Lender) the original or a certified copy of a receipt evidencing payment thereof.

(b)           In addition, Borrower agrees to pay any and all present or future stamp, court or documentary taxes and any other excise or property taxes or charges or similar levies which arise from any payment made under any Loan Document or from the execution, delivery, performance, enforcement or registration of, or otherwise with respect to, any Loan Document (hereinafter referred to as “Other Taxes”).

(c)           If Borrower shall be required to deduct or pay any Taxes or Other Taxes from or in respect of any sum payable under any Loan Document to Agent or any Lender (excluding Taxes for which Borrower is not responsible under Section 3.1(e)), Borrower shall

42

also pay to Agent or to such Lender, as the case may be, at the time interest is paid, such additional amount that Agent or such Lender specifies is necessary to preserve the after-tax yield (after factoring in all taxes, including taxes imposed on or measured by net income) that Agent or such Lender would have received if such Taxes or Other Taxes had not been imposed.

(d)           Borrower agrees to indemnify Agent and each Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section but excluding Taxes for which Borrower is not responsible under Section 3.1(e)) paid by Agent and such Lender, (ii) amounts payable under Section 3.1(c) and (iii) any liability (including additions to tax, penalties, interest and expenses) arising therefrom or with respect thereto, in each case whether or not such Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority.  Payment under this subsection (d) shall be made within 30 days after the date Lender or Agent makes a demand therefor.

(e)           For any period with respect to which a Lender has failed to provide Borrower or Agent with the appropriate form as required by Section 10.19 (whether or not such Lender is lawfully able to do so, unless such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which such form originally was required to be provided), such Lender shall not be entitled to indemnification under this Section 3.1 with respect to Taxes imposed on such Lender; provided that if a Lender, which is otherwise exempt from withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, Borrower shall take such steps as such Lender shall reasonably request, at the Lender’s expense, to assist such Lender to recover such Taxes.

3.2          Illegality.  If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans or IBOR Rate Loans, or to determine or charge interest rates based upon the Eurodollar Rate or IBOR Rate, then, on notice thereof by such Lender to Borrower through Agent, any obligation of such Lender to make or continue Eurodollar Rate Loans or IBOR Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans or IBOR Rate Loans shall be suspended until such Lender notifies Agent and Borrower that the circumstances giving rise to such determination no longer exist.  Upon receipt of such notice, Borrower shall, upon demand from such Lender (with a copy to Agent), prepay or, if applicable, convert all Eurodollar Rate Loans or IBOR Rate Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Rate Loans or IBOR Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans or IBOR Rate Loans.  Upon any such prepayment or conversion, Borrower shall also pay accrued interest on the amount so prepaid or converted and all amounts due under Section 3.5 in accordance with the terms thereof due to such prepayment or conversion.  Each Lender agrees to designate a different Lending Office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender.

3.3          Inability to Determine Rates.  If Agent determines in connection with any request for a Eurodollar Rate Loan or IBOR Rate Loan or a conversion to or continuation thereof

43

for any reason that (a) Dollar deposits are not being offered to banks in the London interbank Eurodollar market for the applicable amount and Interest Period of such Eurodollar Rate Loan or IBOR Rate Loan, (b) adequate and reasonable means do not exist for determining the Eurodollar Base Rate or IBOR Base Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan or IBOR Rate Loan, as applicable, or (c) that the Eurodollar Base Rate or IBOR Base Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan or IBOR Rate Loan, as applicable, does not adequately and fairly reflect the cost to such Lenders of funding such Loan, Agent will promptly so notify Borrower and each Lender.  Thereafter, the obligation of Lenders to make or maintain Eurodollar Rate Loans or IBOR Rate Loans shall be suspended until Agent (upon the instruction of the Required Lenders) revokes such notice.  Upon receipt of such notice, Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans or IBOR Rate Loans or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the amount specified therein.

3.4          Increased Cost and Reduced Return; Capital Adequacy.

(a)           If any Lender determines that as a result of the introduction of or any change in or in the interpretation of any Law, or such Lender’s compliance therewith, there shall be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Loans or IBOR Rate Loans (as the case may be) or issuing or participating in Letters of Credit, or a reduction in the amount received or receivable by such Lender in connection with any of the foregoing (excluding for purposes of this subsection (a) any such increased costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to which Section 3.1 shall govern), (ii) changes in the basis of taxation of overall net income or overall gross income by the United States or any foreign jurisdiction or any political subdivision of either thereof under the Laws of which such Lender is organized or has its Lending Office, and (iii) reserve requirements utilized in the determination of the Eurodollar Rate or IBOR Rate), then from time to time within 5 days after demand of such Lender (with a copy of such demand to Agent), Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such increased cost or reduction.  If as a result of the foregoing, Borrower is required to pay to any Lender any additional amounts, such Lender agrees to use commercially reasonable efforts to designate a different Lending Office if such designation will avoid such increased cost or reduced return and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender.

(b)           If any Lender determines that the introduction of any Law regarding capital adequacy or any change therein or in the interpretation thereof, or compliance by such Lender (or its Lending Office) therewith, has the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of such Lender’s obligations hereunder (taking into consideration its policies with respect to capital adequacy and such Lender’s desired return on capital), then from time to time within 5 days after demand of such Lender (with a copy of such demand to Agent), Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such reduction.

44

3.5          Compensation for Losses.  Upon demand of any Lender (with a copy to Agent) from time to time, Borrower shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:

(a)           any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise); or

(b)           any failure by Borrower (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow, continue or convert any Loan other than a Base Rate Loan on the date or in the amount notified by Borrower; including any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained.  Borrower shall also pay any customary administrative fees charged by such Lender in connection with the foregoing.  For purposes of calculating amounts payable by Borrower to Lenders under this Section 3.5, each Lender shall be deemed to have funded each Eurodollar Rate Loan or IBOR Rate Loan made by it at the Eurodollar Base Rate or IBOR Base Rate used in determining the Eurodollar Rate or IBOR Rate, as applicable, for such Loan by a matching deposit or other borrowing in the London interbank Eurodollar market for a comparable amount and for a comparable period, whether or not such Eurodollar Rate Loan or IBOR Rate Loan was in fact so funded.

3.6          Matters Applicable to all Requests for Compensation.  A certificate of Agent or any Lender claiming compensation under this Article III and setting forth the additional amount or amounts to be paid to it hereunder and setting forth an explanation therefor shall be conclusive in the absence of manifest error.  In determining such amount, Agent or such Lender may use any reasonable averaging and attribution methods.

3.7          Survival.  All of Borrower’s obligations under this Article III shall survive termination of the Aggregate Commitments and repayment of all other Obligations hereunder.

8.3          Application of Funds.  After the exercise of remedies provided for in Section 8.2 (or after the Loans have automatically become immediately due and payable and the L/C Obligations have automatically been required to be Cash Collateralized as set forth in the proviso to Section 8.2), any amounts received on account of the Obligations shall be applied by Agent in the following order:

Subject to Section 2.3(c), amounts used to Cash Collateralize the aggregate undrawn amount of Letters of Credit pursuant to clause Fifth above shall be applied to satisfy drawings under such Letters of Credit as they occur.  If any amount remains on deposit as Cash Collateral after all Letters of Credit have either been fully drawn or expired, such remaining amount shall be applied to the other Obligations, if any, in the order set forth above.

ARTICLE IX.        AGENT

9.1          Appointment and Authorization Agent.

(a)           Each Lender hereby irrevocably appoints, designates and authorizes Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto.  Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall Agent have or be deemed to have any fiduciary relationship with any Lender or participant, 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 Agent.  Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan Documents with reference to Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law.  Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

67

(b)           The L/C Issuer shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the Issuer Documents associated therewith, and the L/C Issuer shall have all of the benefits and immunities (i) provided to Agent in this Article IX with respect to any acts taken or omissions suffered by the L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and the Issuer Documents pertaining to such Letters of Credit as fully as if the term “Agent” as used in this Article IX and in the definition of “Agent-Related Person” included the L/C Issuer with respect to such acts or omissions, and (ii) as additionally provided herein with respect to the L/C Issuer.

9.2          Delegation of Duties.  Agent may execute any of its duties under this Agreement or any other Loan Document by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties.  Agent shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact that it selects in the absence of gross negligence or willful misconduct.

9.3          Liability of Agent.  No Agent-Related Person shall (a) be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct in connection with its duties expressly set forth herein as determined by a final non-appealable judgment by a court of competent jurisdiction), or (b) be responsible in any manner to any Lender or Participant for any recital, statement, representation or warranty made by any Loan Party or any officer thereof, contained herein or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or for any failure of any Loan Party or any other party to any Loan Document to perform its obligations hereunder or thereunder.  No Agent-Related Person shall be under any obligation to any Lender or Participant 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 any Loan Party or any Affiliate thereof.

9.4          Reliance by Agent.

(a)           Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone message, electronic mail message, statement 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 any Loan Party), independent accountants and other experts selected by Agent.  Agent shall be fully justified in failing or refusing to take any action under any Loan Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.  Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Required Lenders (or such greater

number of Lenders as may be expressly required hereby in any instance) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders.

(b)           For purposes of determining compliance with the conditions specified in Section 4.1, each Lender that has signed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless Agent shall have received notice from such Lender prior to the proposed Closing Date specifying its objection thereto.

9.5          Notice of Default.  Agent shall not be deemed to have knowledge or notice of the occurrence of any Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to Agent for the account of the Lenders, unless Agent shall have received written notice from a Lender or Borrower referring to this Agreement, describing such Default and stating that such notice is a “notice of default.”  Agent will notify the Lenders of its receipt of any such notice.  Agent shall take such action with respect to such Default as may be directed by the Required Lenders in accordance with Article VIII; provided, however, that unless and until Agent has received any such direction, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable or in the best interest of the Lenders.

9.6          Credit Decision; Disclosure of Information by Agent.  Each Lender acknowledges that no Agent-Related Person has made any representation or warranty to it, and that no act by Agent hereafter taken, including any consent to and acceptance of any assignment or review of the affairs of any Loan Party or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Lender as to any matter, including whether Agent-Related Persons have disclosed material information in their possession.  Each Lender represents to Agent that it has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the Loan Parties and their respective Subsidiaries, and all applicable bank or other regulatory Laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to Borrower and the other Loan Parties hereunder.  Each Lender also represents that it will, independently and without reliance upon any Agent-Related Person 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 investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of Borrower and the other Loan Parties.  Except for notices, reports and other documents expressly required to be furnished to the Lenders by Agent herein, Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Agent-Related Person.

9.7          Indemnification of Agent.  Whether or not the transactions contemplated hereby are consummated, the Lenders shall indemnify upon demand each Agent-Related Person (to the extent not reimbursed by or on behalf of any Loan Party and without limiting the obligation of any Loan Party to do so), pro rata, and hold harmless each Agent-Related Person from and against any and all Indemnified Liabilities incurred by it; provided, however, that no Lender shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified Liabilities to the extent determined in a final, nonappealable judgment by a court of competent jurisdiction to have resulted from such Agent-Related Person’s own gross negligence or willful misconduct; provided, however, that no action taken in accordance with the directions of the Required Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section.  Without limitation of the foregoing, each Lender shall reimburse Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that Agent is not reimbursed for such expenses by or on behalf of Borrower.  The undertaking in this Section shall survive termination of the Aggregate Commitments, the payment of all other Obligations and the resignation of Agent.

9.8          Agent in its Individual Capacity.  Bank of America and its Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with each of the Loan Parties and their respective Affiliates as though Bank of America were not Agent or the L/C Issuer hereunder and without notice to or consent of the Lenders.  The Lenders acknowledge that, pursuant to such activities, Bank of America or its Affiliates may receive information regarding any Loan Party or its Affiliates (including information that may be subject to confidentiality obligations in favor of such Loan Party or such Affiliate) and acknowledge that Agent shall be under no obligation to provide such information to them.  With respect to its Loans, Bank of America shall have the same rights and powers under this Agreement as any other Lender and may exercise such rights and powers as though it were not Agent or the L/C Issuer, and the terms “Lender” and “Lenders” include Bank of America in its individual capacity.

9.9          Successor Agent.  Agent may resign as Agent upon 30 days’ notice to the Lenders; provided that any such resignation by Bank of America shall also constitute its resignation as L/C Issuer.  If Agent resigns under this Agreement, the Required Lenders shall appoint from among the Lenders a successor administrative agent for the Lenders, which successor administrative agent shall be consented to by Borrower at all times other than during the existence of an Event of Default (which consent of Borrower shall not be unreasonably withheld or delayed).  If no successor administrative agent is appointed prior to the effective date of the resignation of Agent, Agent may appoint, after consulting with the Lenders and Borrower, a successor administrative agent from among the Lenders.  Upon the acceptance of its appointment as successor administrative agent hereunder, the Person acting as such successor administrative agent shall succeed to all the rights, powers and duties of the retiring Agent, L/C Issuer and the respective terms “Agent” and “L/C Issuer” shall mean such successor administrative agent, Letter of Credit issuer, and the retiring Agent’s appointment, powers and

70

duties as Agent shall be terminated and the retiring L/C Issuer’s rights, powers and duties as such shall be terminated, without any other or further act or deed on the part of such retiring L/C Issuer or any other Lender, other than the obligation of the successor L/C Issuer to issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or to make other arrangements satisfactory to the retiring L/C Issuer to effectively assume the obligations of the retiring L/C Issuer with respect to such Letters of Credit.  After any retiring Agent’s resignation hereunder as Agent, the provisions of this Article IX and Sections 10.4 and 10.5 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.  If no successor administrative agent has accepted appointment as Agent by the date which is 30 days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above.

9.10        Agent May File Proofs of Claim.

(a)           In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to any Loan Party, Agent (irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether Agent shall have made any demand on Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

(b)           to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and Agent and their respective agents and counsel and all other amounts due the Lenders and Agent under Sections 2.3(i) and (j), 2.9 and 10.4) allowed in such judicial proceeding; and

(c)           to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to Agent and, in the event that Agent shall consent to the making of such payments directly to the Lenders, to pay to Agent any amount due for the reasonable compensation, expenses, disbursements and advances of Agent and its agents and counsel, and any other amounts due Agent under Sections 2.9 and 10.4.  Nothing contained herein shall be deemed to authorize Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize Agent to vote in respect of the claim of any Lender in any such proceeding.

9.11        Guaranty Matters.  Each Lender hereby irrevocably authorizes Agent, at its option and in its discretion, to release any Guarantor from its obligations under the Guaranty if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder.  Upon

71

request by Agent at any time, each Lender will confirm in writing Agent’s authority to release any Guarantor from its obligations under the Guaranty pursuant to this Section 9.11.

ARTICLE X.         MISCELLANEOUS

10.1        Amendments, Etc.  No amendment or waiver of any provision of this Agreement or any other Loan Document, and no consent to any departure by Borrower or any other Loan Party therefrom, shall be effective unless in writing signed by the Required Lenders and Borrower or the applicable Loan Party, as the case may be, and acknowledged by Agent, and each such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no such amendment, waiver or consent shall:

(g)           release any Guarantor from the Guaranty without the written consent of each Lender; and,

provided further, that (i) no amendment, waiver or consent shall, unless in writing and signed by

72

the L/C Issuer in addition to the Lenders required above, affect the rights or duties of the L/C Issuer under this Agreement or any L/C Application relating to any Letter of Credit issued or to be issued by it; (ii) no amendment, waiver or consent shall, unless in writing and signed by Agent in addition to the Lenders required above, affect the rights or duties of Agent under this Agreement or any other Loan Document; and (iii) the Agent Fee Letter may be amended, or rights or privileges thereunder waived, in a writing executed only by the parties thereto.  Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder, except that the Commitment of such Lender may not be increased or extended without the consent of such Lender.

10.2        Notices and Other Communications; Facsimile Copies.

(a)           General.  Unless otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including by facsimile transmission).  All such written notices shall be mailed, certified or registered mail, faxed or delivered to the applicable address, facsimile number or (subject to subsection (c) below) electronic mail address, and all notices and other communications expressly permitted hereunder to be given by telephone shall be made to the applicable telephone number, as follows:

(b)           Electronic Communications.  Notices and other communications to Lenders hereunder may be delivered or furnished by electronic communication (including e-mail and Internet or intranet websites) pursuant to procedures approved by Agent, provided that the foregoing shall not apply to notices to any Lender pursuant to Article II if such Lender has notified the Agent that it is incapable of receiving notices under such Article by electronic communication.  Agent or Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved

73

by it, provided that approval of such procedures may be limited to particular notices or communications.

(c)           Effectiveness of Facsimile Documents and Signatures.  Loan Documents may be transmitted and/or signed by facsimile.  The effectiveness of any such documents and signatures shall, subject to applicable Law, have the same force and effect as manually-signed originals and shall be binding on all Loan Parties, Agent and the Lenders.  Agent may also require that any such documents and signatures be confirmed by a manually-signed original thereof; provided, however, that the failure to request or deliver the same shall not limit the effectiveness of any facsimile document or signature.

(d)           Reliance by Agent and Lenders.  Agent and the Lenders shall be entitled to rely and act upon any notices (including telephonic Loan Notices) purportedly given by or on behalf of Borrower even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof.  Borrower shall indemnify each Agent-Related Person and each Lender from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of Borrower.  All telephonic notices to and other communications with Agent may be recorded by Agent, and each of the parties hereto hereby consents to such recording.

10.3        No Waiver; Cumulative Remedies.  No failure by any Lender or Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege hereunder 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        Attorney Costs, Expenses and Taxes.  Borrower agrees (a) to pay or reimburse Agent for all costs and expenses incurred in connection with the development, preparation, negotiation and execution of this Agreement and the other Loan Documents and any amendment, waiver, consent or other modification of the provisions hereof and thereof (whether or not the transactions contemplated hereby or thereby are consummated), and the consummation and administration of the transactions contemplated hereby and thereby, including all Attorney Costs, and (b) to pay or reimburse Agent and each Lender for all costs and expenses incurred in connection with the enforcement, attempted enforcement, or preservation of any rights or remedies under this Agreement or the other Loan Documents (including all such costs and expenses incurred during any “workout” or restructuring in respect of the Obligations and during any legal proceeding, including any proceeding under any Debtor Relief Law), including all Attorney Costs.  The foregoing costs and expenses shall include all search, filing, recording, title insurance and appraisal charges and fees and taxes related thereto, and other out-of-pocket expenses incurred by Agent and the cost of independent public accountants and other outside experts retained by Agent or any Lender.  All amounts due under this Section 10.4 shall be payable within ten Business Days after demand therefor.  The agreements in this Section shall survive the termination of the Aggregate Commitments and repayment of all other Obligations.

74

10.5        Indemnification by Borrower.  Whether or not the transactions contemplated hereby are consummated, Borrower shall indemnify and hold harmless each Agent-Related Person, each Lender and their respective Affiliates, directors, officers, employees, counsel, agents and attorneys-in-fact (collectively the “Indemnitees”) from and against any and all liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses and disbursements (including Attorney Costs) of any kind or nature whatsoever which may at any time be imposed on, incurred by or asserted against any such Indemnitee in any way relating to or arising out of or in connection with (a) the execution, delivery, enforcement, performance or administration of any Loan Document or any other agreement, letter or instrument delivered in connection with the transactions contemplated thereby or the consummation of the transactions contemplated thereby, (b) any Commitment, Loan or Letter of Credit or the use or proposed use of the proceeds therefrom (including any refusal by the L/C Issuer to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (c) any actual or alleged presence or release of Hazardous Materials on or from any property currently or formerly owned or operated by Borrower, any Subsidiary or any other Loan Party, or any Environmental Liability related in any way to Borrower, any Subsidiary or any other Loan Party, or (d) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory (including any investigation of, preparation for, or defense of any pending or threatened claim, investigation, litigation or proceeding) and regardless of whether any Indemnitee is a party thereto (all the foregoing, collectively, the “Indemnified Liabilities”), in all cases, whether or not caused by or arising, in whole or in part, out of the negligence of the Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses or disbursements are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.  No Indemnitee shall be liable for any damages arising from the use by others of any information or other materials obtained through IntraLinks or other similar information transmission systems in connection with this Agreement, nor shall any Indemnitee have any liability for any indirect or consequential damages relating to this Agreement or any other Loan Document or arising out of its activities in connection herewith or therewith (whether before or after the Closing Date).  All amounts due under this Section 10.5 shall be payable within ten Business Days after demand therefor.  The agreements in this Section shall survive the resignation of Agent, the replacement of any Lender, the termination of the Aggregate Commitments and the repayment, satisfaction or discharge of all the other Obligations.

10.6        Payments Set Aside.  To the extent that any payment by or on behalf of Borrower is made to Agent or any Lender, or Agent or any Lender exercises its right of set-off, and such payment or the proceeds of such set-off or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by Agent or such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such set-off had not occurred, and (b) each Lender severally agrees to pay to Agent upon demand its applicable share of any amount so recovered from or repaid by Agent,

75

plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect.

10.7        Successors and Assigns.  (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, except that Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (f)  of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void).  Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby, the Indemnitees) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b)           Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans (including for purposes of this subsection (b), participations in L/C Obligations) at the time owing to it); provided that (i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender , the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $5,000,000 unless each of Agent and, so long as no Event of Default has occurred and is continuing, Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed); (ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned; (iii) any assignment of a Commitment must be approved by Agent and the L/C Issuer unless the Person that is the proposed assignee is itself a Lender (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and (iv) the parties to each assignment shall execute and deliver to Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500.  Subject to acceptance and recording thereof by Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement 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 3.1, 3.4, 3.5, 10.4 and 10.5 with respect to facts and circumstances occurring prior to the effective date of such assignment).  Upon request, Borrower (at its expense) shall execute and deliver a Note to the

76

assignee Lender.  Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection 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 subsection (d) of this Section.

(c)           Agent, acting solely for this purpose as an agent of Borrower, shall maintain at Agent’s Office 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 Commitments of, and principal amounts of the 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 Borrower, Agent 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.  The Register shall be available for inspection by Borrower, at any reasonable time and from time to time upon reasonable prior notice.  In addition, at any time that a request for a consent for a material or other substantive change to the Loan Documents is pending, any Lender wishing to consult with other Lenders in connection therewith may request and receive from Agent a copy of the Register.

(d)           Any Lender may at any time, without the consent of, or notice to, Borrower or Agent, sell participations to any Person (other than a natural person or Borrower or any of Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender’s participations in L/C Obligations) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) Borrower, Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.  Any agreement or instrument 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 or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso to Section 10.1 that directly affects such Participant.  Subject to subsection (e) of this Section, Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.4 and 3.5 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section.  To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.9 as though it were a Lender, provided such Participant agrees to be subject to Section 2.13 as though it were a Lender.

(e)           A Participant shall not be entitled to receive any greater payment under Section 3.1 or 3.4 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 Borrower’s prior written consent.

(f)            Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Note, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal

77

Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g)           “Eligible Assignee” as used herein, means (a) a Lender; (b) an Affiliate of a Lender;  and (c) any other Person (other than a natural person) approved by (i) Agent and the L/C Issuer, and (ii) unless an Event of Default has occurred and is continuing, Borrower (each such approval not to be unreasonably withheld or delayed); provided that notwithstanding the foregoing, “Eligible Assignee” shall not include Borrower or any of Borrower’s Affiliates or Subsidiaries.

(h)           If the consent of Borrower to an assignment to an Eligible Assignee is required hereunder (including a consent to an assignment which does not meet the minimum assignment threshold specified in clause (i) of the proviso to the first sentence of Section 10.7(b)), Borrower shall be deemed to have given its consent five Business Days after the date notice thereof has been delivered to Borrower by the assigning Lender (through Agent) unless such consent is expressly refused by Borrower prior to such fifth Business Day.

(i)            Notwithstanding anything to the contrary contained herein, if at any time Bank of America assigns all of its Commitment and Loans pursuant to subsection (b) above, Bank of America may, upon 30 days’ notice to Borrower and the Lenders, resign as L/C Issuer.  In the event of any such resignation as L/C Issuer, Borrower shall be entitled to appoint from among the Lenders a successor L/C Issuer hereunder; provided, however, that no failure by Borrower to appoint any such successor shall affect the resignation of Bank of America as L/C Issuer.  If Bank of America resigns as L/C Issuer, it shall retain all the rights and obligations of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as L/C Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.3(c)).

10.8        Confidentiality.  Each of Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and representatives(it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to Borrower and its obligations, (g) with the consent of Borrower or (h) to the extent such Information (x) becomes publicly available other than as a result of a

breach of this Section or (y) becomes available to Agent or any Lender on a nonconfidential basis from a source other than Borrower.  For purposes of this Section, “Information” means all information received from Borrower or any of its Subsidiaries relating to Borrower or any Subsidiary or any of their respective businesses, other than any such information that is available to Agent or any Lender on a nonconfidential basis prior to disclosure by Borrower or any Subsidiary, provided that, in the case of information received from a Borrower or any Subsidiary after the date hereof, such information is clearly identified at the time of delivery as confidential.  Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

10.9        Set-off.  In addition to any rights and remedies of the Lenders provided by law, upon the occurrence and during the continuance of any Event of Default, each Lender is authorized at any time and from time to time, without prior notice to Borrower or any other Loan Party, any such notice being waived by Borrower (on its own behalf and on behalf of each Loan Party) to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other indebtedness at any time owing by, such Lender to or for the credit or the account of the respective Loan Parties against any and all Obligations owing to such Lender hereunder or under any other Loan Document, now or hereafter existing, irrespective of whether or not Agent or such Lender shall have made demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured or denominated in a currency different from that of the applicable deposit or indebtedness.  Each Lender agrees promptly to notify Borrower and Agent after any such set-off and application made by such Lender; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application.

10.10      Interest Rate Limitation.  Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”).  If Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to Borrower.  In determining whether the interest contracted for, charged, or received by Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

10.11      Counterparts.  This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

10.12      Integration.  This Agreement, together with the other Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and thereof and supersedes all prior agreements, written or oral, on such subject matter.  In the event of any conflict between the provisions of this Agreement and those of any other Loan Document,

79

the provisions of this Agreement shall control; provided that the inclusion of supplemental rights or remedies in favor of Agent or the Lenders in any other Loan Document shall not be deemed a conflict with this Agreement.  Each Loan Document was drafted with the joint participation of the respective parties thereto and shall be construed neither against nor in favor of any party, but rather in accordance with the fair meaning thereof.

10.13      Survival of Representations and Warranties.  All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof.  Such representations and warranties have been or will be relied upon by Agent and each Lender, regardless of any investigation made by Agent or any Lender or on their behalf and notwithstanding that Agent or any Lender may have had notice or knowledge of any Default at the time of any Credit Extension, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

10.14      Severability.  If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions.  The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

10.15      Governing Law; Submission to Jurisdiction.

(a)           THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT AGENT AND EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

(b)           ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE UNITED STATES FOR THE CENTRAL DISTRICT OF SUCH STATE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, BORROWER, AGENT AND EACH LENDER CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS.  BORROWER, AGENT AND EACH LENDER IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED THERETO.  BORROWER, AGENT AND EACH LENDER WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER

80

PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH STATE.

10.16      Waiver of Right to Trial by Jury.

EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

10.17      USA Patriot Act Notice. Each Lender and Agent (for itself and not on behalf of any Lender) hereby notifies Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies Borrower, which information includes the name and address of Borrower and other information that will allow such Lender or Agent, as applicable, to identify Borrower in accordance with the Act.

10.18      Time of the Essence.  Time is of the essence of the Loan Documents.

10.19      Foreign Lenders.  Each Lender that is a “foreign corporation, partnership or trust” within the meaning of the Code shall deliver to Agent, prior to receipt of any payment subject to withholding under the Code (or after accepting an assignment of an interest herein), two duly signed completed copies of either Form W-8BEN or any successor thereto (relating to such Person and entitling it to a complete exemption from withholding on all payments to be made to such Person by Borrower pursuant to this Agreement) or Form W-8ECI or any successor thereto (relating to all payments to be made to such Person by Borrower pursuant to this Agreement) of the IRS or such other evidence satisfactory to Borrower and Administrative Agent that no withholding under the federal income tax laws is required with respect to such Person.  Thereafter and from time to time, each such Person shall (a) promptly submit to Agent such additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may then be available under then current United States laws and regulations to avoid, or such evidence as is satisfactory to Borrower and Agent of any available exemption from, United States withholding taxes in respect of all payments to be made to such Person by Borrower pursuant to this Agreement, and (b) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as may be reasonably necessary (including the re-designation of its Lending Office) to avoid any requirement of applicable Laws that Borrower make any deduction or withholding for taxes from amounts payable to such Person.  If such

81

Persons fail to deliver the above forms or other documentation, then Agent and Borrower may withhold from any interest payment to such Person an amount equivalent to the applicable withholding tax imposed by Sections 1441 and 1442 of the Code, without reduction.  If any Governmental Authority asserts that Agent did not properly withhold any tax or other amount from payments made in respect of such Person, such Person shall indemnify Agent therefor, including all penalties and interest and costs and expenses (including Attorney Costs) of Agent.  The obligation of Lenders under this Section shall survive the payment of all Obligations and the resignation or replacement of Agent.

82

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the date first above written.
