5

available (the “Transaction Date”) to Consolidated Fixed Charges of such Person for the Four-Quarter Period. In addition to and without limitation of the foregoing, for purposes of this definition, “Consolidated EBITDA” and “Consolidated Fixed Charges” shall be calculated after giving effect on a pro forma basis for the period of such calculation to (i) the incurrence or repayment of any Indebtedness or the issuance of any Designated Preferred Stock of such Person or any of its Restricted Subsidiaries (and the application of the proceeds thereof) giving rise to the need to make such calculation and any incurrence or repayment of other Indebtedness or the issuance or redemption of other Preferred Stock (and the application of the proceeds thereof), other than the incurrence or repayment of Indebtedness in the ordinary course of business for working capital purposes pursuant to revolving credit facilities, occurring during the Four-Quarter Period or at any time subsequent to the last day of the Four-Quarter Period and on or prior to the Transaction Date, as if such incurrence or repayment or issuance or redemption, as the case may be (and the application of the proceeds thereof), had occurred on the first day of the Four-Quarter Period; and (ii) any Asset Sales or other dispositions or Asset Acquisitions (including any Asset Acquisition giving rise to the need to make such calculation as a result of such Person or one of its Restricted Subsidiaries (including any Person who becomes a Restricted Subsidiary as a result of the Asset Acquisition) incurring, assuming or otherwise being liable for Acquired Indebtedness and also including any Consolidated EBITDA attributable to the assets which are the subject of the Asset Acquisition or Asset Sale or other disposition and without regard to clause (iv) of the definition of Consolidated Net Income) occurring during the Four-Quarter Period or at any time subsequent to the last day of the Four Quarter Period and on or prior to the Transaction Date, as if such Asset Sale or other disposition or Asset Acquisition (including the incurrence or assumption of any such Acquired Indebtedness) occurred on the first day of the Four-Quarter Period.  If such Person or any of its Restricted Subsidiaries directly or indirectly guarantees Indebtedness of a third Person, the preceding sentence shall give effect to the incurrence of such guaranteed Indebtedness as if such Person or any Restricted Subsidiary of such Person had directly incurred or otherwise assumed such other Indebtedness that was so guaranteed.

Furthermore, in calculating “Consolidated Fixed Charges” for purposes of determining the denominator (but not the numerator) of this “Consolidated Fixed Charge Coverage Ratio”:  (i) interest on outstanding Indebtedness determined on a fluctuating basis as of the Transaction Date and which will continue to be so determined thereafter shall be deemed to have accrued at a fixed rate per annum equal to the rate of interest on such Indebtedness in effect on the Transaction Date; and (ii) notwithstanding clause (i) of this paragraph, interest on Indebtedness determined on a fluctuating basis, to the extent such interest is covered by agreements relating to Interest Swap Obligations, shall be deemed to accrue at the rate per annum resulting after giving effect to the operation of such agreements.

For purposes of this definition, whenever pro forma effect is to be given to an acquisition of assets, the amount of income or earnings relating thereto and the amount of Consolidated Interest Expense associated with any Indebtedness incurred in connection therewith, the pro forma calculations shall be determined in good faith by a responsible financial or accounting officer of the Borrower.  In addition, any such pro forma calculation may include adjustments appropriate, in the reasonable determination of the Borrower as set forth in an Officers’ Certificate, to reflect operating expense reductions reasonably expected to result from any acquisition or merger.

corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans hereunder and (ii) in the case of such Lender, a rate determined by the Administrative Agent to represent its cost of overnight or short-term funds (which determination shall be conclusive absent manifest error).

(d)                                 The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligation to lend hereunder (it being understood, however, that the Commitments of the Lenders are several and no Lender shall be responsible for the failure of any other Lender to make any Loan required to be made by such other Lender.  Each Lender may at its option make any Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement.

30

made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement.

(d)                                 The entries made in the accounts maintained pursuant to paragraphs (b) and (c) above shall be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrower to repay the Loans in accordance with their terms.

(e)                                  Any Lender may request that Loans made by it hereunder be evidenced by a promissory note.  In such event, the Borrower shall execute and deliver to such Lender a promissory note payable to such Lender and its registered assigns and in a form and substance reasonably acceptable to the Administrative Agent and the Borrower.  Notwithstanding any other provision of this Agreement, in the event any Lender shall request and receive such a promissory note, the interests represented by such note shall at all times (including after any assignment of all or part of such interests pursuant to Section 8.04) be represented by one or more promissory notes payable to the payee named therein or its registered assigns.

(b)                                 Interest on each Loan shall be payable to the Lenders, through the Administrative Agent, on the Interest Payment Dates applicable to such Loan except as otherwise provided in this Agreement.  The Adjusted LIBO Rate for each Interest Period or day within an Interest Period, as the case may be, shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

31

SECTION 2.06.            Optional Prepayments.  (a)  The Borrower shall have the right at any time and from time to time to prepay the Loans, in whole or in part, upon at least three Business Days’ prior written or fax notice (or telephonic notice promptly confirmed by written notice), to the Administrative Agent before 12:00 (noon), New York City time; provided, however, that each partial prepayment shall be in an amount that is an integral multiple of $500,000 and not less than $1,000,000; provided, however, that no optional prepayment shall be permitted under this Section 2.06 (x) if at such time there is less than $100.0 million of aggregate principal amount of Loans outstanding or (y) to the extent that, after giving effect thereto, there would be less than $100.0 million in aggregate principal amount of Loans outstanding, unless in either case such optional prepayment is in an amount equal to the entire aggregate principal amount of Loans outstanding at such time.

(b)                                 Each notice of optional prepayment shall specify the prepayment date and the principal amount of the Loans to be prepaid, shall be irrevocable and shall commit the Borrower to prepay the amount stated therein on the date stated therein.  All prepayments under this Section 2.06 shall be subject to Section 2.08 but otherwise without premium or penalty.  All optional prepayments under this Section 2.06 shall be accompanied by accrued and unpaid interest on the principal amount to be prepaid to but excluding the date of payment.

SECTION 2.07.            Reserve Requirements; Change in Circumstances.  (a)  Notwithstanding any other provision of this Agreement, if any Change in Law shall impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of or credit extended by any Lender (except any such reserve requirement which is reflected in the Adjusted LIBO Rate) or shall impose on such Lender or the London interbank market any other condition affecting this Agreement or Loans made by such Lender, and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Loan or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), in each case, by an amount deemed by such Lender to be material, then the Borrower will pay to such Lender upon demand such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b)                                 If any Lender shall have determined that any Change in Law regarding capital adequacy has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by such Lender pursuant hereto to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time the Borrower shall pay to such Lender, as the case may be, such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c)                                  A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as applicable, as specified in paragraph (a) or (b) above shall be delivered to the Borrower and shall be conclusive absent manifest error.  The

32

Borrower shall pay such Lender the amount shown as due on any such certificate delivered by it within 10 days after its receipt of the same.

(d)                                 Failure or delay on the part of any Lender to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be under any obligation to compensate any Lender under paragraph (a) or (b) above with respect to increased costs or reductions with respect to any period prior to the date that is 120 days prior to such request if such Lender knew or could reasonably have been expected to know of the circumstances giving rise to such increased costs or reductions and of the fact that such circumstances would result in a claim for increased compensation by reason of such increased costs or reductions; provided further that the foregoing limitation shall not apply to any increased costs or reductions arising out of the retroactive application of any Change in Law within such 120-day period.  The protection of this Section shall be available to each Lender regardless of any possible contention of the invalidity or inapplicability of the Change in Law that shall have occurred or been imposed.

SECTION 2.08.            Indemnity.  The Borrower shall indemnify each Lender against any loss or expense that such Lender may sustain or incur as a consequence of (a) any event, other than a default by such Lender in the performance of its obligations hereunder, which results in (i) such Lender receiving or being deemed to receive any amount on account of the principal of any Loan prior to the end of the Interest Period in effect therefor, or (ii) any Loan to be made by such Lender not being made after notice of such Loan shall have been given by the Borrower hereunder (any of the events referred to in this clause (a) being called a “Breakage Event”) or (b) any default in the making of any payment or prepayment required to be made hereunder.  In the case of any Breakage Event, such loss shall include an amount equal to the excess, as reasonably determined by such Lender, of (i) its cost of obtaining funds for the Loan that is the subject of such Breakage Event for the period from the date of such Breakage Event to the last day of the Interest Period in effect (or that would have been in effect) for such Loan over (ii) the amount of interest likely to be realized by such Lender in redeploying the funds released or not utilized by reason of such Breakage Event for such period, but such loss shall not, in any event, include any lost profit or loss of applicable margin.  A certificate of any Lender setting forth any amount or amounts which such Lender is entitled to receive pursuant to this Section 2.08 shall be delivered to the Borrower and shall be conclusive absent manifest error.

SECTION 2.09.            Pro Rata Treatment.  Except as provided in Section 2.16, each Borrowing, each payment or prepayment of principal of any Borrowing, each payment of interest on the Loans and each reduction of the Commitments shall be allocated pro rata among the Lenders in accordance with their respective Commitments (or, if the Commitments shall have expired or been terminated, in accordance with the respective principal amounts of their outstanding Loans).  Each Lender agrees that in computing such Lender’s portion of any Borrowing to be made hereunder, the Administrative Agent may, in its discretion, round each Lender’s percentage of such Borrowing to the next higher or lower whole dollar amount.

SECTION 2.10.            Sharing of Setoffs.  Each Lender agrees that if it shall, through the exercise of a right of banker’s lien, setoff or counterclaim against the Borrower, obtain payment (voluntary or involuntary) in respect of any Loan as a result of which the unpaid portion of its

33

Loans shall be proportionately less than the unpaid portion of the Loans of any other Lender, it shall be deemed simultaneously to have purchased from such other Lender at face value, and shall promptly pay to such other Lender the purchase price for, a participation in the Loans of such other Lender, so that the aggregate unpaid amount of the Loans and participations in Loans held by each Lender shall be in the same proportion to the aggregate unpaid amount of all Loans then outstanding as the amount of its Loans prior to such exercise of banker’s lien, setoff or counterclaim or other event was to the amount of all Loans outstanding prior to such exercise of banker’s lien, setoff or counterclaim or other event; provided, however, that if any such purchase or purchases or adjustments shall be made pursuant to this Section 2.10 and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest.  The Borrower expressly consents to the foregoing arrangements and agrees that any Lender holding a participation in a Loan deemed to have been so purchased may exercise any and all rights of banker’s lien, setoff or counterclaim with respect to any and all moneys owing by the Borrower to such Lender by reason thereof as fully as if such Lender had made a Loan directly to the Borrower in the amount of such participation.

SECTION 2.11.            Payments.  (a)  The Borrower shall make each payment (including principal of or interest on any Loan or any fees or other amounts) hereunder and under any other Loan Document not later than 12:00 (noon), New York City time, on the date when due in immediately available dollars, without setoff, defense or counterclaim.  Each such payment shall be made to the Administrative Agent at the Administrative Agent’s Office, or at such other location as the Administrative Agent shall notify the Borrower from time to time in accordance with Section 8.01.  The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof.

(b)                                 Except as otherwise expressly provided herein, whenever any payment (including principal of or interest on any Loan or any fees or other amounts) hereunder or under any other Loan Document shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest or fees, if applicable.

SECTION 2.12.            Taxes.  (a)  Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (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) the Administrative Agent or such Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

34

(c)                                  The Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto (other than penalties or interest attributable to (i) a failure or delay by the Administrative Agent or such Lender, as applicable, in making such written demand to the Borrower or (ii) the gross negligence or wilful misconduct of the Administrative Agent or such Lender, as applicable), whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority.  A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender, or by the Administrative Agent on its behalf or on behalf of a Lender, shall be conclusive absent manifest error.

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

(e)                                  Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate.

SECTION 2.13.            Assignment of Commitments Under Certain Circumstances; Duty to Mitigate.  (a)  In the event (i) any Lender delivers a certificate requesting compensation pursuant to Section 2.07, (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority on account of any Lender pursuant to Section 2.12 or (iii) any Lender refuses to consent to any amendment, waiver or other modification of any Loan Document requested by the Borrower that requires the consent of a greater percentage of the Lenders than the Required Lenders and such amendment, waiver or other modification is consented to by the Required Lenders, the Borrower may, at its sole expense and effort (including with respect to the processing and recordation fee referred to in Section 8.04(b)), upon notice to such Lender and the Administrative Agent, require such Lender to transfer and assign, without recourse, representation or warranty, except as to warranty as to its ownership of the assigned obligations (in accordance with and subject to the restrictions contained in Section 8.04), all of its interests, rights and obligations under this Agreement to an assignee that shall assume such assigned obligations and, with respect to clause (iii) above, shall consent to such requested amendment, waiver or other modification of any Loan Document (which assignee may be another Lender, if a Lender accepts such assignment); provided that (x) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority having jurisdiction, (y) the Borrower shall have received the prior written consent of the Administrative Agent,

35

which consent shall not unreasonably be withheld, and (z) the Borrower or such assignee shall have paid to the affected Lender in immediately available funds an amount equal to the sum of the principal of and interest accrued to the date of such payment on the outstanding Loans of such Lender plus all other amounts accrued for the account of such Lender hereunder (including any amounts under Section 2.07 and Section 2.08); provided further that, if prior to any such transfer and assignment the circumstances or event that resulted in such Lender’s claim for compensation under Section 2.07 or the amounts paid pursuant to Section 2.12, as the case may be, cease to cause such Lender to suffer increased costs or reductions in amounts received or receivable or reduction in return on capital, or cease to result in amounts being payable under Section 2.12, as the case may be (including as a result of any action taken by such Lender pursuant to paragraph (b) below), or if such Lender shall waive its right to claim further compensation under Section 2.07 in respect of such circumstances or event or shall waive its right to further payments under Section 2.12 in respect of such circumstances or event or shall consent to the proposed amendment, waiver, consent or other modification, as the case may be, then such Lender shall not thereafter be required to make any such transfer and assignment hereunder.

(b)                                 If (i) any Lender shall request compensation under Section 2.07, or (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority on account of any Lender, pursuant to Section 2.12, then such Lender shall use reasonable efforts (which shall not require such Lender to incur an unreimbursed loss or unreimbursed cost or expense or otherwise take any action inconsistent with its internal policies or legal or regulatory restrictions or suffer any disadvantage or burden deemed by it to be significant) (x) to file any certificate or document reasonably requested in writing by the Borrower or (y) to assign its rights and delegate and transfer its obligations hereunder to another of its offices, branches or Affiliates, if such filing or assignment would reduce its claims for compensation under Section 2.07 or would reduce amounts payable pursuant to Section 2.12, as the case may be, in the future.  The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such filing or assignment, delegation and transfer.

SECTION 2.14.            Change of Control.  (a)  The Borrower shall (i) within thirty (30) days following the occurrence of a Change of Control, make an offer to all Lenders to prepay all Loans pursuant to a Change in Control Offer (as defined in paragraph (b) of this Section 2.14) at a purchase price in cash equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the date of prepayment, in accordance with the terms contemplated in this Section 2.14; and (ii) prepay all the Loans of all Lenders properly accepting such offer of prepayment in accordance with such Change of Control Offer.

(b)                                 A “Change of Control Offer” means a notice delivered to the Administrative Agent (which will promptly furnish such notice to the Lenders) stating:

(i)                                     that a Change of Control has occurred and that such Lender has the right to require the Borrower to prepay all or a portion of such Lender’s Loans at a purchase price in cash equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the date of prepayment;

36

(ii)                                  the Change of Control prepayment date (which shall be no earlier than thirty (30) days nor later than sixty (60) days from the date such notice is delivered);

(iii)                               that any Loans as to which such offer is not properly accepted will remain outstanding and continue to accrue interest;

(iv)                              unless the Borrower defaults in the payment of the purchase price of any Loans as to which the Change of Control Offer shall have been accepted, all Loans accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control prepayment date;

(v)                                 Lenders electing to have any Loans purchased pursuant to a Change of Control Offer will be required to notify the Administrative Agent prior to the close of business on the third Business Day preceding the Change of Control prepayment date; and

(vi)                              that Lenders will be entitled to withdraw their election to require the Borrower to prepay their Loans; provided that the Administrative Agent receives, not later than the close of business on the last day of the offer period, a notice setting forth the name of the Lender, the principal amount of Loans tendered for prepayment, and a statement that such Lender is withdrawing its election to have such Loans prepaid.

(c)                                  On the prepayment date, the Borrower shall prepay the Loans of all Lenders who accept the Change of Control Offer at a purchase price in cash equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of prepayment.  All prepayments of Loans under this Section 2.14 shall be subject to Section 2.08.

(d)                                 Notwithstanding the foregoing provisions of this Section, the Borrower shall be deemed to have made a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in Section 2.14(b) applicable to a Change of Control Offer made by the Borrower and prepays all Loans as to which offers for prepayment have been validly accepted and not withdrawn pursuant to the terms of such Change of Control Offer.

(e)                                  A Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for such Change of Control at the time of making of the Change of Control Offer.

SECTION 2.15.            Asset Sale Offer.  (a)  On the Asset Sale Offer Trigger Date, as determined in accordance with Section 5.04, the Borrower shall (i) make an offer to all Lenders and, if required by the terms of any other Senior Indebtedness of the Borrower, to the holders of such Senior Indebtedness (other than with respect to Hedging Obligations) in accordance with the procedures set forth below, to prepay the maximum aggregate principal amount of Loans and prepay or purchase the maximum principal amount of such Senior Indebtedness that is an integral multiple of $1,000 that may be purchased out of the aggregate Asset Sale Amount at a prepayment or purchase price in cash equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the date of prepayment or repurchase, in accordance with the terms contemplated in this Section 2.15; and (ii) prepay all the Loans of Lenders properly

(e)                                  Pending the final application of any Net Cash Proceeds pursuant to this Section 2.15, the Borrower or the applicable Restricted Subsidiary of the Borrower may apply such Net Cash Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such Net Cash Proceeds in any manner not prohibited hereunder.

good faith judgment of the Borrower prudent in the ordinary course of business of the Borrower and its Subsidiaries.

SECTION 3.19.            Labor Matters.  As of the Closing Date, there are no strikes, lockouts or slowdowns against the Borrower or any Subsidiary of the Borrower pending or, to the knowledge of the Borrower, threatened.  The consummation of the Transactions will not give rise to any right of termination or right of renegotiation on the part of any union under any collective bargaining agreement to which the Borrower or any Subsidiary of the Borrower is bound.  Except to the extent any of the following, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect, (a) the hours worked by and payments made to employees of the Borrower and its Subsidiaries have not been in violation in any material respect of the Fair Labor Standards Act or any other applicable Federal, state, local or foreign law dealing with such matters and (b) all payments due from the Borrower or any Subsidiary of the Borrower, or for which any claim may be made against the Borrower or any Subsidiary of the Borrower, on account of wages and employee health and welfare insurance and other benefits, have been paid or accrued as a liability on the books of the Borrower or such Subsidiary.

SECTION 3.20.            Solvency.  Immediately after the consummation of the Transactions to occur on the Closing Date, (a) the fair value of the assets of the Borrower and its Restricted Subsidiaries, taken as a whole, at a fair valuation, will exceed its debts and liabilities, subordinated, contingent or otherwise; (b) the present fair saleable value of the property of the Borrower and its Restricted Subsidiaries, taken as a whole, will be greater than the amount that will be required to pay the probable liability of their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (c) the Borrower and its Restricted Subsidiaries, taken as a whole, will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (d) the Borrower and its Restricted Subsidiaries, taken as a whole, will not have unreasonably small capital with which to conduct the business in which they are engaged as such business is now conducted and is proposed to be conducted following the Closing Date.

SECTION 5.01.            Restricted Payments.  The Borrower shall not, and shall not cause or permit any of its Restricted Subsidiaries to, directly or indirectly:

(a)                                  declare or pay any dividend or make any distribution on or in respect of shares of the Borrower or any of its Restricted Subsidiaries’ Capital Stock to holders of such Capital Stock (other than dividends or distributions payable in Qualified Capital Stock of the Borrower and dividends or distributions payable to the Borrower or a Restricted of the Borrower and other than pro rata dividends or other distributions made by a Subsidiary of the Borrower that is not a Wholly Owned Subsidiary to minority stockholders (or owners of an equivalent interest in the case of a Subsidiary that is an entity other than a corporation));

(b)                                 purchase, redeem or otherwise acquire or retire for value any Capital Stock of the Borrower or of any direct or indirect parent of the Borrower or of a Restricted Subsidiary of the Borrower held by any Affiliate of the Borrower (other than a Restricted Subsidiary of the Borrower) or any warrants, rights or options to purchase or acquire shares of any class of such Capital Stock;

(c)                                  make any principal payment on, purchase, defease, redeem, prepay, decrease or otherwise acquire or retire for value, prior to any scheduled final maturity, scheduled repayment or scheduled sinking fund payment, any Indebtedness of the Borrower that is subordinate or junior in right of payment to the Loans (other than the purchase, defeasance or other acquisition of such Indebtedness purchased in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of such purchase, defeasance or other acquisition); or

(d)                                 make any Investment (other than Permitted Investments)

45

(each of the foregoing actions set forth in clauses (a), (b), (c) and (d) being referred to as a “Restricted Payment”); if at the time of such Restricted Payment or immediately after giving effect thereto:

(i)            a Default or an Event of Default shall have occurred and be continuing; or

(ii)           (A) if the Restricted Payment is made by the Borrower or any of its Restricted Subsidiaries (other than TransDigm and any of its Restricted Subsidiaries) the Borrower is not able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with Section 5.03(i) or, (B) if the Restricted Payment is made by TransDigm or any of its Restricted Subsidiaries, TransDigm is not able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with Section 5.03(ii); or

(iii)          the aggregate amount of Restricted Payments (including such proposed Restricted Payment) made subsequent to the Measurement Date (other than Restricted Payments made pursuant to clauses (2), (3), (4), (5), (6), (9), (10), (11) and (12) of the following paragraph) shall exceed the sum of, without duplication:

(v)           50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of such loss) of the Borrower earned subsequent to June 30, 2003 and on or prior to the date the Restricted Payment occurs (the “Reference Date”) (treating such period as a single accounting period); provided, however, that if, at the time of a proposed Restricted Payment under this paragraph of this Section 5.01, the Consolidated Leverage Ratio of the Borrower is less than 4.5 to 1, for purposes of calculating the availability of amounts hereunder for such Restricted Payment only, the reference to 50% in this clause (v) shall be deemed to be 75%; plus

(w)          100% of the aggregate net cash proceeds (including the fair market value of property other than cash that would constitute Marketable Securities or a Permitted Business) received by the Borrower from any Person (other than a Subsidiary of the Borrower) from the issuance and sale subsequent to the Measurement Date and on or prior to the Reference Date of Qualified Capital Stock of the Borrower; plus

(x)            without duplication of any amounts included in clause (iii)(w) above, 100% of the aggregate net cash proceeds of any equity contribution received subsequent to the Measurement Date by the Borrower from a holder of the Borrower’s Capital Stock (excluding, in the case of clauses (iii)(w) and (x), any net cash proceeds from an Equity Offering (as such term is defined in the TransDigm Indenture) to the extent used to redeem the TransDigm Notes in compliance with the provisions set forth under Section 3.07(b) of the TransDigm Indenture; plus

(y)           the amount by which Indebtedness of the Borrower or any of its Restricted Subsidiaries is reduced on the Borrower’s balance sheet upon the

46

conversion or exchange subsequent to the Measurement Date of any Indebtedness of the Borrower or any of its Restricted Subsidiaries for Qualified Capital Stock of the Borrower (less the amount of any cash, or the fair value of any other property, distributed by the Borrower upon such conversion or exchange); provided, however, that the foregoing amount shall not exceed the net cash proceeds received by the Borrower or any such Restricted Subsidiary from the sale of such Indebtedness (excluding net cash proceeds from sales to a Subsidiary of the Borrower or to an employee stock ownership plan or a trust established by the Borrower or any of its Subsidiaries for the benefit of their employees); plus

(z)            an amount equal to the sum of (I) 100% of the aggregate net proceeds (including the fair market value of property other than cash that would constitute Marketable Securities or a Permitted Business) received after the Measurement Date by the Borrower or any Restricted Subsidiary of the Borrower (A) from any sale or other disposition of any Investment (other than a Permitted Investment) in any Person (including an Unrestricted Subsidiary) made by the Borrower and its Restricted Subsidiaries and (B) representing the return of capital or principal (excluding dividends and distributions otherwise included in Consolidated Net Income) with respect to such Investment, and (II) the portion (proportionate to the Borrower’s equity interest in an Unrestricted Subsidiary) of the fair market value of the net assets of an Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary; provided, however, that, in the case of item (II), the foregoing sum shall not exceed, in the case of any Unrestricted Subsidiary, the amount of Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Borrower or any Restricted Subsidiary in such Unrestricted Subsidiary.

Notwithstanding the foregoing, the provisions set forth in the immediately preceding paragraph shall not prohibit:

(1)                                  the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of the declaration of such dividend or notice of such redemption if the dividend or payment of the redemption price, as the case may be, would have been permitted on the date of declaration or notice;

(2)                                  any Restricted Payment made out of the net cash proceeds of the substantially concurrent sale of, or made by exchange for, Qualified Capital Stock of the Borrower (other than Capital Stock issued or sold to a Subsidiary of the Borrower or an employee stock ownership plan or to a trust established by the Borrower or any of its Subsidiaries for the benefit of their employees and other than Designated Preferred Stock) or a substantially concurrent cash capital contribution received by the Borrower from its shareholders; provided, however, that the net cash proceeds from such sale or such cash capital contribution (to the extent so used for such Restricted Payment) shall be excluded from the calculation of amounts under clauses (iii)(w) and (iii)(x) of the immediately preceding paragraph;

(3)                                  the acquisition of any Indebtedness of the Borrower that is subordinate or junior in right of payment to the Loans through the application of net proceeds of a substantially

47

concurrent sale for cash (other than to a Subsidiary of the Borrower) of Refinancing Indebtedness that is subordinate or junior in right of payment to the Loans;

(4)                                  payments to redeem or repurchase the Borrower’s common equity or options in respect thereof, in each case in connection with the repurchase provisions of employee stock option or stock purchase agreements or other agreements to compensate management employees or upon the death, disability, retirement, severance or termination of employment of management employees; provided that all such redemptions or repurchases pursuant to this clause (4) shall not exceed in any fiscal year the sum of (A) $5.0 million plus (B) any amounts not utilized in any preceding fiscal year following the Measurement Date that were otherwise available under this clause for such purchases (which aggregate amount shall be increased by the amount of any net cash proceeds received from the sale since the Measurement Date of Capital Stock (other than Disqualified Capital Stock) to members of the Borrower’s management team that have not otherwise been applied to the payment of Restricted Payments pursuant to the terms of clause (iii) of the immediately preceding paragraph or clause (2) of this paragraph and by the cash proceeds of any “key-man” life insurance policies which are used to make such redemptions or repurchases); provided, further, that the cancellation of Indebtedness owing to the Borrower from members of management of the Borrower or any of its Restricted Subsidiaries in connection with any repurchase of Capital Stock of the Borrower (or warrants or options or rights to acquire such Capital Stock) will not be deemed to constitute a Restricted Payment under this Agreement;

(5)                                  repurchases of Capital Stock deemed to occur upon the exercise of stock options if such Capital Stock represents a portion of the exercise price thereof;

(6)                                  the Bonus and Dividend Payments in an amount not to exceed the net proceeds of the Loans;

(7)                                  Restricted Payments made with Net Cash Proceeds from Asset Sales remaining after application thereof as required by Section 5.04 and Section 2.15;

(8)                                  upon occurrence of a Change of Control and within 60 days after the completion of the Change of Control Offer pursuant to Section 2.14 (including the purchase of all Loans tendered), any purchase or redemption of Obligations of the Borrower that are subordinate or junior in right of payment to the Loans required pursuant to the terms thereof as a result of such Change of Control at a purchase or redemption price not to exceed 101% of the outstanding principal amount thereof, plus accrued and unpaid interest thereon, if any; provided, however, that (A) at the time of such purchase or redemption, no Default or Event of Default shall have occurred and be continuing (or would result therefrom), (B) the Borrower would be able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with Section 5.03(i)  after giving pro forma effect to such Restricted Payment and (C) such purchase or redemption is not made, directly or indirectly, from the proceeds of (or made in anticipation of) any issuance of Indebtedness by the Borrower or any Subsidiary of the Borrower;

(9)                                  additional Restricted Payments in an aggregate amount not to exceed $15 million

48

(10)                            if no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof, the declaration and payment of dividends to holders of any class or series of Designated Preferred Stock (other than Disqualified Capital Stock) issued after the Measurement Date; provided that, (i) in the case of a dividend by the Borrower and its Restricted Subsidiaries (other than TransDigm and its Restricted Subsidiaries), at the time of such dividend, the Borrower, after giving effect to such dividend on a pro forma basis, would have had a Consolidated Fixed Charge Coverage Ratio of at least 1.75 to 1.0 and (ii) in the case of a dividend by TransDigm and its Restricted Subsidiaries, at the time of such dividend, TransDigm, after giving effect to such dividend on a pro forma basis, would have had a Consolidated Fixed Charge Coverage Ratio of at least 2.0 to 1.0;

(11)                            payments of dividends on Disqualified Capital Stock issued in compliance with Section 5.03; and

(12)                            Permitted Acquisition Payments (as such term is defined in the TransDigm Indenture).

In determining the aggregate amount of Restricted Payments made subsequent the Measurement Date in accordance with clause (iii) of the first paragraph of this Section 5.01, (a) amounts expended pursuant to clauses (1), (7) and (8) of the immediately preceding paragraph shall be included in such calculation, and (b) amounts expended pursuant to clauses (2), (3), (4), (5), (6), (9), (10), (11) and (12) of the immediately preceding paragraph shall be excluded from such calculation.

The Board of Directors of the Borrower may designate any Restricted Subsidiary of the Borrower to be an Unrestricted Subsidiary as specified in the definition of “Unrestricted Subsidiary”.  For purposes of making such determination, all outstanding Investments by the Borrower and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated shall be deemed to be Restricted Payments at the time of the designation and shall reduce the amount available for Restricted Payments under the first paragraph of this Section 5.01.  All of those outstanding Investments shall be deemed to constitute Investments in an amount equal to the fair market value of the Investments at the time of such designation.  Such designation shall only be permitted if the Restricted Payment would be permitted at the time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

Notwithstanding anything herein to the contrary, and in addition to the limits set forth in this Section 5.01, the aggregate amount of (i) all Restricted Payments covered in clauses (a) through (c) of the definition of Restricted Payments made on or after the Closing Date to the holders (either as such or in their capacity as holders of subordinated debt) of Capital Stock of the Borrower or any direct or indirect parent of the Borrower (which shall include the Permitted Holders and their respective Affiliates) (other than a Restricted Payment made pursuant to clause (4) above or the Bonus and Dividend Payments) and (ii) all Investments made on or after the Closing Date in any Permitted Holders or Permitted Group or their respective Affiliates (other than the Borrower and its Subsidiaries and members of management of the Borrower) shall not exceed (x) prior to the initial Public Equity Offering, the amount set forth in clause (9) above (minus the amount of all Restricted Payments already made pursuant to such clause on or after

49

the Closing Date) and (y) following the initial Public Equity Offering, the sum of (A) the amount set forth in clause (9) above (minus the amount of all Restricted Payments already made pursuant to such clause on or after the Closing Date) and (B) 25% of the cumulative Consolidated Net Income of the Borrower earned subsequent to October 31, 2005 and on or prior to the date the Restricted Payment or Investment occurs (treating such period as a single accounting period).

SECTION 5.02.            Dividend and Other Payment Restrictions Affecting Subsidiaries.  The Borrower shall not, and shall not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary of the Borrower to: (a) pay dividends or make any other distributions on or in respect of its Capital Stock; (b) make loans or advances or pay any Indebtedness or other obligation owed to the Borrower; or (c) transfer any of its property or assets to the Borrower, except, with respect to clauses (a), (b) and (c), for such encumbrances or restrictions existing under or by reason of: (1) applicable law; (2) this Agreement; (3) non-assignment provisions of any contract or any lease of any Restricted Subsidiary of the Borrower entered into in the ordinary course of business; (4) any instrument governing Acquired Indebtedness, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired; (5) the TransDigm Credit Agreement as in effect on the Closing Date and the TransDigm Indenture or any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that any restrictions imposed pursuant to any such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing are ordinary and customary with respect to syndicated bank loans or high yield debt securities, as applicable (and in each case under the relevant circumstances); (6) agreements existing on the Closing Date to the extent and in the manner such agreements are in effect on the Closing Date; (7) restrictions on the transfer of assets subject to any Lien permitted under this Agreement imposed by the holder of such Lien; (8) restrictions imposed by any agreement to sell assets or Capital Stock permitted under this Agreement to any Person pending the closing of such sale; (9) any agreement or instrument governing Capital Stock of any Person that is acquired; (10) any Purchase Money Note or other Indebtedness or other contractual requirements of a Securitization Entity in connection with a Qualified Securitization Transaction; provided that such restrictions apply only to such Securitization Entity; (11) other Indebtedness or Permitted Subsidiary Preferred Stock outstanding on the Closing Date or permitted to be issued or incurred under this Agreement; provided that any such restrictions are ordinary and customary with respect to the type of Indebtedness being incurred or Preferred Stock being issued (under the relevant circumstances); (12) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business; and (13) any encumbrances or restrictions imposed by any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1) through (4) and (6) through (12) above; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Borrower’s Board of Directors (evidenced by a Board Resolution) whose judgment shall be conclusively binding, not materially more restrictive with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing.

50

SECTION 5.03.            Incurrence of Indebtedness.  The Borrower shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively, “incur”) any Indebtedness (other than Permitted Indebtedness); provided, however, that if no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the incurrence of any such Indebtedness (i) the Borrower and its Restricted Subsidiaries (other than TransDigm and its Restricted Subsidiaries) may, subject to the provisions of the following sentence, incur Indebtedness, in each case if on the date of the incurrence of such Indebtedness, after giving effect to the incurrence thereof, the Consolidated Fixed Charge Coverage Ratio of the Borrower would have been greater than 1.75 to 1.0 and (ii) notwithstanding that the Borrower and its Restricted Subsidiaries (other than TransDigm and its Restricted Subsidiaries) may not be entitled to incur Indebtedness pursuant to clause (i) above, TransDigm and any of its Restricted Subsidiaries may incur Indebtedness in each case if on the date of the incurrence of such Indebtedness, after giving effect to the incurrence thereof, the Consolidated Fixed Charge Coverage Ratio of TransDigm would have been at least 2.0 to 1.0.

SECTION 5.04.            Asset Sales.  The Borrower shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless

(a)                                  the Borrower or the applicable Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets sold or otherwise disposed of (as determined in good faith by the Borrower’s Board of Directors);

(b)                                 at least 75% of the consideration received by the Borrower or the Restricted Subsidiary, as the case may be, from such Asset Sale shall be in the form of cash or Cash Equivalents; provided that the amount of: (i) any liabilities (as shown on the Borrower’s or such Restricted Subsidiary’s most recent balance sheet) of the Borrower or any such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Loans) that are assumed by the transferee of any such assets; (ii) any notes or other obligations received by the Borrower or any such Restricted Subsidiary from such transferee that are converted by the Borrower or such Restricted Subsidiary into cash within 90 days of the receipt thereof (to the extent of the cash received); and (iii) any Designated Noncash Consideration received by the Borrower or any of its Restricted Subsidiaries in such Asset Sale having an aggregate fair market value, taken together with all other Designated Noncash Consideration received pursuant to this clause (iii) that is at that time outstanding, not to exceed 5% of Total Assets at the time of the receipt of such Designated Noncash Consideration (with the fair market value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value), shall, in each of (i), (ii) and (iii) above, be deemed to be cash for the purposes of this provision or for purposes of this Section 5.04(b); and

(c)                                  upon the consummation of an Asset Sale, the Borrower shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 425 days of receipt thereof either (i) to prepay any Senior Indebtedness of the

51

Borrower (including the Loans) or any Indebtedness of a Restricted Subsidiary of the Borrower and, in the case of any such Indebtedness under any revolving credit facility, effect a corresponding reduction in the availability under such revolving credit facility (or effect a permanent reduction in the availability under such revolving credit facility regardless of the fact that no prepayment is required in order to do so (in which case no prepayment should be required)), (ii) to reinvest in Productive Assets (provided that this requirement shall be deemed satisfied if the Borrower or such Restricted Subsidiary by the end of such 425-day period has entered into a binding agreement under which it is contractually committed to reinvest in Productive Assets and such investment is consummated within 120 days from the date on which such binding agreement is entered into and, with respect to the amount of such investment, the reference to the 426^th day after an Asset Sale in the second following sentence shall be deemed to be a reference to the 121^st day after the date on which such binding agreement is entered into (but only if such 121^st day occurs later than such 426^th day)), or (iii) a combination of prepayment and investment permitted by the foregoing clauses (c)(i) and (c)(ii).  On the 426th day after an Asset Sale or such earlier date, if any, as the Board of Directors of the Borrower or of such Restricted Subsidiary determines by Board Resolution not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (c)(i), (c)(ii) and (c)(iii) of the next preceding sentence (each, an “Asset Sale Offer Trigger Date”), such aggregate amount of Net Cash Proceeds which have not been applied on or before such Asset Sale Offer Trigger Date as permitted in clauses (c)(i), (c)(ii) and (c)(iii) of the next preceding sentence (each an “Asset Sale Offer Amount”) shall be applied by the Borrower to make an Asset Sale Offer in accordance with Section 2.15.  Notwithstanding the foregoing, if an Asset Sale Offer Amount is less than $10.0 million, the application of the Net Cash Proceeds constituting such Asset Sale Offer Amount to an Asset Sale Offer may be deferred until such time as such Asset Sale Offer Amount plus the aggregate amount of all Asset Sale Offer Amounts arising subsequent to the Asset Sale Offer Trigger Date relating to such initial Asset Sale Offer Amount from all Asset Sales by the Borrower and its Restricted Subsidiaries aggregates at least $10.0 million, at which time the Borrower or such Restricted Subsidiary shall apply all Net Cash Proceeds constituting all Asset Sale Offer Amounts that have been so deferred to make a Asset Sale Offer in accordance with Section 2.15 (the first date the aggregate of all such deferred Asset Sale Offer Amounts is equal to $10.0 million or more shall be deemed to be a Asset Sale Offer Trigger Date).

Notwithstanding the immediately preceding paragraph, the Borrower and its Restricted Subsidiaries shall be permitted to consummate an Asset Sale without complying with such paragraph to the extent that: (i) at least 75% of the consideration for such Asset Sale constitutes Productive Assets, cash, Cash Equivalents and/or Marketable Securities; and (ii) such Asset Sale is for fair market value; provided that any consideration consisting of cash, Cash Equivalents and/or Marketable Securities received by the Borrower or any of its Restricted Subsidiaries in connection with any Asset Sale permitted to be consummated under this paragraph shall constitute Net Cash Proceeds subject to the provisions of the preceding paragraph.

Notwithstanding the foregoing provisions of this Section 5.04, if at the time the Borrower would be required to make an Asset Sale Offer pursuant to Section 5.04(c) the Borrower does

The Administrative Agent

Each of the Lenders hereby irrevocably appoints the Administrative Agent its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto.

The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary of the Borrower or other Affiliate thereof as if it were not the Administrative Agent hereunder.

The Administrative Agent shall have no duties or obligations except those expressly set forth in the Loan Documents.  Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 8.08), and (c) except as expressly set forth in the Loan Documents, the Administrative Agent shall have no duty to disclose, nor shall it be liable for the failure to disclose, any information relating to the Borrower or any of the Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity.  The Administrative Agent shall be not liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 8.08) or in the absence of its own gross negligence or wilful misconduct.  The Administrative Agent shall not be deemed to have knowledge of any Default, except with respect to defaults in the payment of principal, interest and fees required to

60

be paid to the Administrative Agent for the account of the Lenders,  unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper person.  The Administrative Agent may also rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper person, and shall not incur any liability for relying thereon.  The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by it.  The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers by or through their respective Related Parties.  The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided below, the Administrative Agent may resign at any time by notifying the Lenders and the Borrower.  Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor.  If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank.  Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor.  After an Administrative Agent’s resignation hereunder, the provisions of this Article and Section 8.05 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in

61

respect of any actions taken or omitted to be taken by any of them while acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.  Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement or any other Loan Document, any related agreement or any document furnished hereunder or thereunder.

(b)                                 Each Lender may assign to one or more assignees all or a portion of its interests, rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it) with notice to the Borrower and the Administrative Agent; provided, however, that (i) the amount of the Loans or Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $1,000,000 (or, if less, the entire remaining amount of such Lender’s Loans or Commitment), (ii) the parties to each such assignment shall (A) electronically execute and deliver to the Administrative Agent an Assignment and Acceptance via an electronic settlement system acceptable to the Administrative Agent (which initially shall be ClearPar, LLC) or (B) manually execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500 (unless such fee is waived at the discretion of the Administrative Agent) and (iii) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire and all applicable tax documentation.  Upon recording pursuant to paragraph (e) of this Section 8.04, from and after the effective date specified in each Assignment and Acceptance, (A) the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement and (B) the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.07, 2.08, 2.12 and 8.05, as well as to any fees accrued for its account and not yet paid).

63

(c)                                  By executing and delivering an Assignment and Acceptance, the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows:  (i) such assigning Lender warrants that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim and that its Commitment, and the outstanding balances of its Loans, in each case without giving effect to assignments thereof which have not become effective, are as set forth in such Assignment and Acceptance, (ii) except as set forth in (i) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto, or the financial condition of the Borrower or any Subsidiary of the Borrower or the performance or observance by the Borrower or any Subsidiary of the Borrower of any of its obligations under this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto; (iii) such assignee represents and warrants that it is legally authorized to enter into such Assignment and Acceptance; (iv) such assignee confirms that it has received a copy of this Agreement, together with copies of the most recent financial statements referred to in Section 3.05 or delivered pursuant to Section 5.14 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (v) such assignee will independently and without reliance upon the Administrative Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (vi) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent, by the terms hereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

(d)                                 The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in Charlotte, North Carolina a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”).  The entries in the Register shall be conclusive and the Borrower, the Administrative Agent 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 the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(e)                                  Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, an Administrative Questionnaire (including all applicable tax documentation) completed in respect of the assignee (unless the assignee shall already be a Lender hereunder) and the processing and recordation fee referred to in paragraph (b) above, if any, the Administrative Agent shall promptly record the information contained in such Assignment and Acceptance in the Register.  No assignment shall be effective unless it has been recorded in the Register as provided in this paragraph (e).

64

(f)                                    Each Lender may, without notice to Borrower or the Administrative Agent, sell participations to one or more banks or other entities in all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided, however, 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, (iii) the participating banks or other entities shall be entitled to the benefit of the cost protection provisions contained in Sections 2.07, 2.08 and 2.12 to the same extent as if they were Lenders (but, with respect to any particular participant, to no greater extent than the Lender that sold the participation to such participant) and (iv) the Borrower, the Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrower relating to the Loans and to approve any amendment, modification or waiver of any provision of this Agreement (other than amendments, modifications or waivers decreasing any fees payable hereunder or the amount of principal of or the rate at which interest is payable on the Loans, extending any scheduled principal payment date or date fixed for the payment of interest on the Loans, or increasing or extending the Commitments).

(g)                                 Any Lender or participant may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.04, disclose to the assignee or participant or proposed assignee or participant any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any such disclosure of information designated by the Borrower as confidential, each such assignee or participant or proposed assignee or participant shall execute an agreement whereby such assignee or participant shall agree (subject to customary exceptions) to preserve the confidentiality of such confidential information on terms no less restrictive than those applicable to the Lenders pursuant to Section 8.16.

(h)                                 Any Lender may (without notice to the Borrower or the Administrative Agent) at any time assign all or any portion of its rights under this Agreement to secure extensions of credit to such Lender or in support of obligations owed by such Lender (including, if such Lender is a fund that invests in bank loans, to a trustee for holders of obligations owed, or securities issued, by such fund); provided that no such assignment shall release a Lender from any of its obligations hereunder or substitute any such assignee for such Lender as a party hereto and any foreclosure or exercise of remedies by such assignee or trustee shall be subject to the provisions of this Section 8.04 regarding assignments in all respects.

(i)                                     Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof.  The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender.  Each party hereto hereby

65

agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender).  In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof.  In addition, notwithstanding anything to the contrary contained in this Section 8.04, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions (consented to by the Borrower and Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC.

(j)                                     Neither Holdings nor the Borrower shall assign or delegate any of its rights or duties hereunder without the prior written consent of the Administrative Agent and each Lender, and any attempted assignment without such consent shall be null and void.

SECTION 8.05.            Expenses; Indemnity.  (a)  The Borrower agrees, to pay all out-of-pocket expenses incurred by the Arrangers in connection with the syndication of the credit facilities provided for herein and by the Administrative Agent in connection with the preparation and administration of this Agreement and the other Loan Documents or in connection with any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions hereby or thereby contemplated shall be consummated) or incurred by the Administrative Agent or any Lender in connection with the enforcement or protection of its rights in connection with this Agreement and the other Loan Documents or in connection with the Loans made hereunder, including the fees, charges and disbursements of Cravath, Swaine & ▇▇▇▇▇ LLP, counsel for the Administrative Agent, and, in connection with any such enforcement or protection, the fees, charges and disbursements of any other counsel for the Administrative Agent or any Lender.

(b)                                 The Borrower agrees to indemnify the Administrative Agent, each Lender and each Indemnification Related Party of any of the foregoing persons (each such person being called an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including reasonable counsel fees, charges and disbursements, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (i) the execution or delivery of this Agreement or any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto or thereto of their respective obligations hereunder or thereunder or the consummation of the Transactions and the other transactions contemplated hereby or thereby, (ii) the use of the proceeds of the Loans, (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnitee is a party thereto, or (iv) any actual or alleged presence or Release of Hazardous Materials on any property currently or formerly owned or operated by the Borrower or any of its Subsidiaries, or

66

any Environmental Liability related in any way to the Borrower or its Subsidiaries; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or wilful misconduct of such Indemnitee.

(c)                                  To the extent that the Borrower fails to pay any amount required to be paid by it to the Arrangers or the Administrative Agent under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Arrangers or the Administrative Agent such Lender’s pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Arrangers or the Administrative Agent in its capacity as such.  For purposes hereof, a Lender’s “pro rata share” shall be determined based upon its share of the sum of the outstanding Loans and Commitments at the time.

(d)                                 To the extent permitted by applicable law, the Borrower shall not assert, and each hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or the use of the proceeds thereof.

(e)                                  The provisions of this Section 8.05 shall remain operative and in full force and effect regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Loans, the expiration of the Commitments, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of the Administrative Agent or any Lender.  All amounts due under this Section 8.05 shall be payable on written demand therefor.

SECTION 8.06.            Right of Setoff.  If an Event of Default shall have occurred and be continuing, each Lender is hereby authorized at any time and from time to time, except to the extent prohibited by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement and other Loan Documents held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement or such other Loan Document and although such obligations may be unmatured.  The rights of each Lender under this Section 8.06 are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 8.07.            Applicable Law.  THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (OTHER THAN AS EXPRESSLY SET FORTH IN OTHER LOAN DOCUMENTS) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

SECTION 8.08.            Waivers; Amendment.  (a)  No failure or delay of the Administrative Agent or any Lender in exercising any power or right hereunder or under any other Loan

67

Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power.  The rights and remedies of the Administrative Agent and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have.  No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.  No notice or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

(b)                                 Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders; provided, however, that no such agreement under this Section 8.08(b) shall (i) decrease the principal amount of, or extend the maturity of or date for the payment of any interest on any Loan, or waive or excuse any such payment or any part thereof, or decrease the rate of interest on any Loan, without the prior written consent of each Lender affected thereby, (ii) increase or extend the Commitment or decrease or extend the date for payment of any fees of or any other amount actually due and payable hereunder to any Lender without the prior written consent of such Lender, (iii) amend or modify the pro rata requirements of Section 2.09, the provisions of Section 8.04(j) or the provisions of this Section, without the prior written consent of each Lender, (iv) modify the protections afforded to an SPC pursuant to the provisions of Section 8.04(i) without the written consent of such SPC, (v) reduce the percentage contained in the definition of the term “Required Lenders” without the prior written consent of each Lender (it being understood that with the consent of the Required Lenders, additional extensions of credit pursuant to this Agreement may be included in the determination of the Required Lenders on substantially the same basis as the Commitments on the date hereof); provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder or under any other Loan Document without the prior written consent of the Administrative Agent.

SECTION 8.09.            Interest Rate Limitation.  Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section 8.09 shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

68

SECTION 8.10.            Entire Agreement.  This Agreement, the Fee Letter and the other Loan Documents constitute the entire contract between the parties relative to the subject matter hereof.  Any other previous agreement among the parties with respect to the subject matter hereof is superseded by this Agreement and the other Loan Documents.  Nothing in this Agreement or in the other Loan Documents, expressed or implied, is intended to confer upon any person (other than the parties hereto and thereto, their respective successors and assigns permitted hereunder and, to the extent expressly contemplated hereby, the Indemnification Related Parties of each of the Administrative Agent and the Lenders) any rights, remedies, obligations or liabilities under or by reason of this Agreement or the other Loan Documents.

SECTION 8.11.            WAIVER OF JURY TRIAL.  EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS.  EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8.11.

SECTION 8.12.            Severability.  In the event any one or more of the provisions contained in this Agreement or in any other Loan Document should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction).  The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 8.13.            Counterparts.  This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original but all of which when taken together shall constitute a single contract, and shall become effective as provided in Section 8.03.  Delivery of an executed signature page to this Agreement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Agreement.

SECTION 8.14.            Headings.  Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.

SECTION 8.15.            Jurisdiction; Consent to Service of Process.  (a)  The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising

69

out of or relating to this Agreement or the other Loan Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court.  Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.  Nothing in this Agreement shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or the other Loan Documents against the Borrower or its properties in the courts of any jurisdiction.

(b)                                 The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the other Loan Documents in any New York State or Federal court.  Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(c)                                  The Borrower irrevocably consents to service of process in the manner provided for notices in Section 8.01.  Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 8.16.            Confidentiality.  (a)  Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (i) to its and its Affiliates’ officers, directors, employees and agents, including accountants, legal counsel and other advisors (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), (ii) to the extent requested by any regulatory authority or quasi-regulatory authority (such as the National Association of Insurance Commissioners), (iii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iv) in connection with the exercise of any remedies hereunder or under the other Loan Documents or any suit, action or proceeding relating to the enforcement of its rights hereunder or thereunder, (v) subject to an agreement containing provisions substantially the same as those of this Section 8.16, to (A) any actual or prospective assignee of or participant in any of its rights or obligations under this Agreement and the other Loan Documents or (B) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower or any Subsidiary of the Borrower or any of their respective obligations, (vi) with the consent of the Borrower or (vii) to the extent such Information becomes publicly available other than as a result of a breach of this Section 8.16.  For the purposes of this Section, “Information” shall mean all information received from the Borrower and related to the Borrower or its business, other than any such information that was available to the Administrative Agent or any Lender on a nonconfidential basis prior to its disclosure by the Borrower; provided that, in the case of Information received from the Borrower after the Closing Date, 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 8.16 shall be considered to have complied with its obligation to do so if such person

70

has exercised the same degree of care to maintain the confidentiality of such Information as such person would accord its own confidential information.

(b)                                 Notwithstanding anything herein to the contrary, any party subject to confidentiality obligations hereunder or otherwise (and any Affiliate thereof and any employee, representative or other agent of such party or such Affiliate) may disclose to any and all persons, without limitation of any kind, the U.S. federal income tax treatment and the U.S. federal income tax structure of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to it relating to such tax treatment and tax structure.

SECTION 8.17.            USA PATRIOT Act Notice.  Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the USA PATRIOT Act.

71

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.
