5

Indebtedness had been Incurred on the first day of such period, (B) if the Company or any Restricted Subsidiary has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of such period or if any Indebtedness is to be repaid, repurchased, defeased or otherwise discharged (in each case other than Indebtedness Incurred under any revolving credit facility or similar arrangement to finance seasonal fluctuations in working capital needs, unless such Indebtedness has been permanently repaid and the related commitment has been terminated and not been replaced) on the date of the transaction giving rise to the need to calculate the Consolidated Coverage Ratio, Consolidated EBITDA and Consolidated Interest Expense for such period shall be calculated on a pro forma basis as if such discharge had occurred on the first day of such period and as if the Company or such Restricted Subsidiary has not earned the interest income actually earned during such period in respect of cash or Temporary Cash Investments used to repay, repurchase, defease or otherwise discharge such Indebtedness, (C) if since the beginning of such period the Company or any Restricted Subsidiary shall have made any Asset Disposition, the Consolidated EBITDA for such period shall be reduced by an amount equal to the Consolidated EBITDA (if positive) directly attributable to the assets that are the subject of such Asset Disposition for such period or increased by an amount equal to the Consolidated EBITDA (if negative) directly attributable thereto for such period and Consolidated Interest Expense for such period shall be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale), (D) if since the beginning of such period the Company or any Restricted Subsidiary (by merger or otherwise) shall have made an Investment in any Restricted Subsidiary (or any Person that becomes a Restricted Subsidiary) or an acquisition of assets, including any acquisition of assets occurring in connection with a transaction causing a calculation to be made hereunder, which constitutes all or substantially all of an operating unit of a business, Consolidated EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the first day of such period and (E) if since the beginning of such period any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) shall have made any Asset Disposition or any Investment or acquisition of assets that would have required an adjustment pursuant to clause (C) or (D) above if made by the Company or a Restricted Subsidiary during such period, Consolidated EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto as if such Asset Disposition, Investment or acquisition of assets occurred on the first day of such period.

For purposes of this definition, whenever pro forma effect is to be given to an acquisition of assets or other Investment, 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 Company and shall comply with the requirements of Rule 11-02 of Regulation S-X promulgated by the Commission.

6

If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement has a remaining term as at the date of determination in excess of 12 months).  If the interest on any such Indebtedness may be determined based on rates chosen by the Company, pro forma interest expense may be determined based on such optional rate chosen as the Company may designate.

13.                                 Discharge and Defeasance

Subject to certain conditions, the Company at any time may terminate some of or all its obligations under the Notes and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Notes to redemption or maturity, as the case may be.

14.                                 Amendment, Waiver

Upon such a declaration, such principal and interest will be due and payable immediately. However, if any Designated Senior Indebtedness of the Company is outstanding, the Company may not pay the Notes until five Business Days after such holders or the Representative of such Designated Senior Indebtedness receives notice of such acceleration and, thereafter, may pay the Notes only if the subordination provisions of the Indenture otherwise permit payment at that time. If an Event of Default relating to specified events of bankruptcy, insolvency or reorganization of the Company occurs, the principal of and interest on all the Notes will become immediately due and payable without any declaration or other act on the part of

30

the trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences.

No Holder of any Note shall have any right, by virtue or by availing of any provision of the Indenture, to institute any action or proceeding at law or in equity or in bankruptcy or otherwise with respect to the Indenture, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy under the Indenture, unless such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof and the Holders of not less than 25% in aggregate principal amount of the Notes then Outstanding shall have made written request upon the Trustee to institute such action or proceedings in its own name as trustee under the Indenture and shall have offered to the Trustee security or indemnity reasonably satisfactory to it as it may require, against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee for 60 days after its receipt of such notice, request and offer of security or indemnity shall have failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee during such 60-day period by Holders of a majority in principal amount of the Notes then Outstanding.  No one or more Holders of Notes shall have any right in any manner whatever, by virtue or by availing of any provision of the Indenture, to affect, disturb or prejudice the rights of any other such Holder of Notes, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under the Indenture, except in the manner provided in the Indenture and for the equal, ratable and common benefit of all Holders of the Notes.

16.                                 Trustee Dealings With the Company

Subject to certain limitations imposed by the TIA, the Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

17.                                 No Recourse Against Others

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or in any Note shall be had against any incorporator as such or against any past, present or future shareholder, employee, officer or director of the Company, any Subsidiary Guarantor or of any successor, either directly or through the Company, any Subsidiary Guarantor or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Notes by the Holders thereof and as part of the consideration for the issue of the Notes.

(c)                                  Notwithstanding any other provision of this Section 3.06, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may Incur pursuant to this Section 3.06 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rates of currencies.  For purposes of determining the outstanding amount of any particular Indebtedness Incurred pursuant to this Section 3.06;

(i)                                     Indebtedness Incurred pursuant to the Credit Agreement prior to or on the Closing Date shall be treated as Incurred pursuant to Section 3.06(b)(i) above,

(ii)                                  Indebtedness permitted by this Section 3.06 need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 3.06 permitting such Indebtedness, and

(iii)                               in the event that Indebtedness meets the criteria of more than one of the types of Indebtedness described in this Section 3.06, the Company, in its sole discretion, shall classify (and, except as provided in Section 3.06(c)(i), may later reclassify) such Indebtedness and only be required to include the amount of such Indebtedness in one of such clauses.

37

(y) dividends or distributions payable to the Company or a Restricted Subsidiary (and, if such Restricted Subsidiary has shareholders other than the Company or other Restricted Subsidiaries, to its other shareholders on a pro rata basis or on a basis more favorable to the Company and its Restricted Subsidiaries than pro rata),

(ii)                                  purchase, repurchase, redeem, retire or otherwise acquire for value any Capital Stock of the Company held by Persons other than the Company or a Restricted Subsidiary,

(iii)                               purchase, repurchase, redeem, retire, defease or otherwise acquire for value, prior to scheduled maturity, scheduled repayment or scheduled sinking fund payment any Subordinated Obligations (other than the purchase, repurchase redemption, retirement, defeasance or other acquisition for value of Subordinated Obligations acquired in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of acquisition), or

(iv)                              make any Investment (other than a Permitted Investment) in any Person

(any such dividend, distribution, payment, purchase, redemption, repurchase, defeasance, retirement, other acquisition or Investment being herein referred to as a “Restricted Payment”) if at the time the Company or such Restricted Subsidiary makes such Restricted Payment:

(1)                                  a Default shall have occurred and be continuing (or would result therefrom);

(2)                                  the Company could not Incur at least $1.00 of additional Indebtedness under Section 3.06(a); or

(3)                                  the aggregate amount of such Restricted Payment and all other Restricted Payments (the amount so expended, if other than in cash, to be determined in good faith by the Board of Directors, whose determination shall be conclusive and evidenced by a resolution of the Board of Directors) declared or made subsequent to April 1, 2001 (other than Restricted Payments excluded pursuant to Section 3.07(b) below) would exceed the sum, without duplication, of:

(A)                              50% of the Consolidated Net Income accrued during the period (treated as one accounting period) from April 1, 2001, to the end of the most recent fiscal quarter for which financial statements are publicly available prior to the date of such Restricted Payment (or, in case such Consolidated Net Income is a deficit, minus 100% of such deficit);

38

(B)                                the aggregate Net Cash Proceeds received by the Company from the issue or sale of its Capital Stock (other than Disqualified Stock) subsequent to April 1, 2001 (other than an issuance or sale to (x) a Restricted Subsidiary of the Company or (y) an employee stock ownership plan or other trust established by the Company or any of its Subsidiaries);

(D)                               the amount by which Indebtedness of the Company or its Restricted Subsidiaries issued after April 1, 2001 is reduced on the Company’s consolidated balance sheet upon the conversion or exchange of such Indebtedness for Capital Stock (other than Disqualified Stock) of the Company (less the amount of any cash or the Fair Market Value of other property distributed by the Company or any Restricted Subsidiary upon such conversion or exchange); and

(E)                                 with respect to Investments (other than Permitted Investments) made by the Company and its Restricted Subsidiaries after April 1, 2001, an amount equal to the net reduction in such Investments in any Person resulting from repayments of loans or advances, or other transfers of assets, in each case to the Company or any Restricted Subsidiary or from the net cash proceeds from the sale of any such Investment (except, in each case, to the extent any such payment or proceeds are included in the calculation of Consolidated Net Income), from dividends or other distributions or payments on such Investments, or from the release of any Guarantee (except to the extent any amounts are paid under such Guarantee) or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries, not to exceed, in each case, the amount of such Investments previously made by the Company or any Restricted Subsidiary in such Person or Unrestricted Subsidiary after April 1, 2001.

39

(b)                                 The provisions of Section 3.07(a) shall not prohibit:

(i)                                     any dividend or distribution in respect of, or any purchase, repurchase, redemption, retirement or other acquisition for value of Capital Stock of the Company or Subordinated Obligations of the Company or any Subsidiary Guarantor made by exchange for, or out of the proceeds of the substantially concurrent sale of, Capital Stock of the Company (other than Disqualified Stock and other than Capital Stock issued or sold to a Restricted Subsidiary of the Company or an employee stock ownership plan or other trust established by the Company or any of its Subsidiaries); provided, however, that:

(1)                                  such dividend, distribution, purchase, repurchase, redemption, retirement or other acquisition for value shall be excluded in the calculation of the amount of Restricted Payments, and

(iii)                               any prepayment, repayment, purchase, repurchase, redemption, retirement, defeasance or other acquisition for value of Subordinated Obligations from Net Available Cash to the extent permitted by Section 3.09; provided, however, that such prepayment, repayment, purchase, repurchase, redemption, retirement, defeasance or other acquisition for value shall be excluded in the calculation of the amount of Restricted Payments;

(iv)                              dividends paid within 60 days after the date of declaration thereof if at such date of declaration such dividends would have complied with this Section 3.07; provided, however, that such dividends (without duplication) will be included in the calculation of the amount of Restricted Payments;

40

(v)                                 any purchase, repurchase, redemption, retirement or other acquisition for value of shares of, or options to purchase shares of, common stock of the Company or any of its Subsidiaries from employees, former employees, directors or former directors of the Company or any of its Subsidiaries (or permitted transferees of such employees, former employees, directors or former directors), pursuant to the terms of agreements (including employment agreements) or plans (or amendments thereto) approved by the Board of Directors under which such individuals purchase or sell or are granted the option to purchase or sell, shares of such common stock; provided, however, that the aggregate amount of such purchases, repurchases, redemptions, retirements and other acquisitions for value shall not exceed $10,000,000 in any calendar year; provided further, however, that such purchases, repurchases, redemptions, retirements and other acquisitions for value shall be excluded in the calculation of the amount of Restricted Payments;

(vi)                              the repurchase of Capital Stock deemed to occur upon the exercise of options or warrants to the extent that such Capital Stock represents all or a portion of the exercise price thereof; provided, however, that such repurchases shall be excluded from the calculation of the amount of Restricted Payments;

SECTION 3.08                    Limitation on Restrictions on Distributions from Restricted Subsidiaries.  The Company will not, and will not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(a)                                  pay dividends or make any other distributions on its Capital Stock or pay any Indebtedness or other obligations owed to the Company;

(b)                                 make any loans or advances to the Company; or

41

(c)                                  transfer any of its property or assets to the Company,

except:

(i)                                     any encumbrance or restriction pursuant to applicable law, rule, regulation or order or an agreement in effect at or entered into on the Closing Date;

(ii)                                  any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement relating to any Indebtedness Incurred by such Restricted Subsidiary prior to the date on which such Restricted Subsidiary was acquired by the Company or any Restricted Subsidiary (other than Indebtedness Incurred as consideration in, in contemplation of, or to provide all or any portion of the funds or credit support utilized to consummate the transaction or series of related transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was otherwise acquired by the Company) and outstanding on such date;

(iii)                               any encumbrance or restriction pursuant to an agreement effecting a Refinancing of Indebtedness Incurred pursuant to an agreement referred to in clause (i) or (ii) of this Section 3.08 or this clause (iii) or contained in any amendment to an agreement referred to in clause (i) or (ii) of this Section 3.08 or this clause (iii); provided, however, that the encumbrances and restrictions contained in any such Refinancing agreement or amendment, taken as a whole, are not materially less favorable to the Holders than the encumbrances and restrictions contained in such predecessor agreements;

(v)                                 any encumbrance or restriction on cash or other deposits or net worth imposed by customers or lessors or required

(ix)                                existing under, by reason of or with respect to Indebtedness Incurred by Foreign Subsidiaries permitted to be Incurred under Section 3.06.

SECTION 3.09  Limitation on Sales of Assets and Subsidiary Stock.

(a)                                  The Company will not, and will not permit any Restricted Subsidiary to, make any Asset Disposition unless:

(i)                                     the Company or such Restricted Subsidiary receives consideration (including by way of relief from, or by any other Person assuming sole responsibility for, any liabilities, contingent or otherwise) at the time of such Asset Disposition at least equal to the Fair Market Value of the shares and assets subject to such Asset Disposition,

(ii)                                  at least 75% of the consideration thereof received by the Company or such Restricted Subsidiary is in the form of cash, assets useful in a Permitted Business or Permitted Securities; provided that the amount of any Designated Non-Cash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Disposition shall be deemed cash for the purposes of this provision (but for no other purpose) so long as such amount, taken together with the Fair Market Value when received of all other Designated Non-Cash Consideration that

43

is at that time outstanding (i.e., that has not been sold for or otherwise converted into cash), does not exceed $35,000,000, and

(iii)                               an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company (or such Restricted Subsidiary, as the case may be) within 360 days after the later of the date of such Asset Disposition or the receipt of such Net Available Cash:

(1)                                  first, to the extent the Company elects (or is required by the terms of any Indebtedness), to prepay, repay, purchase, repurchase, redeem, retire, defease or otherwise acquire for value Senior Indebtedness of the Company, Senior Indebtedness of a Subsidiary Guarantor or Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor (in each case other than Indebtedness owed to the Company or an Affiliate of the Company);

(2)                                  second, to the extent of the balance of Net Available Cash after application, in accordance with clause (1), to the extent the Company or such Restricted Subsidiary elects, to reinvest in Additional Assets (including by means of an Investment in Additional Assets by a Restricted Subsidiary with Net Available Cash received by the Company or another Restricted Subsidiary);

(3)                                  third, to the extent of the balance of such Net Available Cash after application in accordance with clauses (1) and (2), to make an Offer (as defined in Section 3.09(b)) to purchase Notes pursuant to and subject to the conditions of Section 3.09(b); provided, however, that if the Company elects (or is required by the terms of any other Senior Subordinated Indebtedness), such Offer may be made ratably (determined based upon the respective principal amounts of the Notes and such other Senior Subordinated Indebtedness being purchased or repaid) to purchase the Notes and to purchase or otherwise repay such other Senior Subordinated Indebtedness of the Company, and

(4)                                  fourth, to the extent of the balance of such Net Available Cash after application in accordance with clauses (1), (2) and (3), for any general corporate purpose not prohibited by the terms of this Indenture;

provided, however that in connection with any prepayment, repayment, purchase, repurchase, redemption, retirement, defeasance or other acquisition for value of Indebtedness pursuant to clause (1) or (3) above, the Company or such Restricted Subsidiary shall retire such Indebtedness and shall cause the related loan commitment (if any) to be permanently reduced in an amount equal to the

44

principal amount so prepaid, repaid, purchased, repurchased, redeemed, retired, defeased or otherwise acquired for value.

Notwithstanding the foregoing provisions of this Section 3.09, the Company and the Restricted Subsidiaries will not be required to apply any Net Available Cash in accordance with this Section 3.09 except to the extent that the aggregate Net Available Cash from all Asset Dispositions that is not applied in accordance with this Section 3.09 exceeds $50,000,000.

For the purposes of this Section 3.09, the following are deemed to be cash:

(A)                              the assumption of Indebtedness of the Company (other than obligations in respect of Disqualified Stock of the Company) or any Restricted Subsidiary (other than obligations in respect of Disqualified Stock and Preferred Stock of a Subsidiary Guarantor) and the release of the Company or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition and

(B)                                securities received by the Company or any Restricted Subsidiary from the transferee that are promptly converted by the Company or such Restricted Subsidiary into cash.

(b)                                 In the event of an Asset Disposition that requires the purchase of Notes pursuant to Section 3.09(a)(iii)(3), the Company will be required (i) to purchase Notes tendered pursuant to an offer by the Company for the Notes (the “Offer”) at a purchase price of 100% of their principal amount plus accrued and unpaid interest thereon to the date of purchase (subject to the right of Holders of record on the relevant date to receive interest due on the relevant interest payment date) in accordance with the procedures, including prorating in the event of oversubscription, set forth in this Indenture and (ii) to purchase or otherwise repay other Senior Subordinated Indebtedness of the Company on the terms and to the extent contemplated thereby at the purchase price set forth in the relevant documentation (including accrued and unpaid interest to the date of acquisition, the “purchase price”), provided that to the extent the purchase price of any such Senior Subordinated Indebtedness exceeds 100% of the principal amount thereof, plus accrued and unpaid interest thereon to the date of acquisition, the Company shall not use any Net Available Cash to pay such purchase price, except as permitted by the next sentence.  If the aggregate purchase price of Notes (and other Senior Subordinated Indebtedness) tendered pursuant to the Offer is less than the Net Available Cash allotted to the purchase of the Notes (and other Senior Subordinated Indebtedness), the Company shall apply the remaining Net Available Cash in accordance with Section 3.09(a)(iii)(4).  The Company shall not be required to make an Offer for Notes (and other Senior Subordinated Indebtedness) pursuant to this Section 3.09 if the Net Available Cash available therefor (after application of the proceeds as provided in clauses (1) and (2) of Section 3.09(a)(iii)) is less than $50,000,000 for any particular Asset Disposition (which lesser amount will be carried forward for purposes of determining whether

45

an Offer is required with respect to the Net Available Cash from any subsequent Asset Disposition).

(c)                                  (i)                                     Promptly, and in any event within 10 days after the Company becomes obligated to make an Offer, the Company shall be obligated to deliver to the Trustee and send or, at the request of the Company have the Trustee send, in the name and on behalf of the Company, by first-class mail to each Holder, a written notice stating that the Holder may elect to have its Notes purchased by the Company either in whole or in part (subject to prorating as hereinafter described in the event the Offer is oversubscribed) in integral multiples of $1,000 of principal amount, at the applicable purchase price.  The notice shall specify a purchase date not less than 30 days nor more than 60 days after the date of such notice (the “Purchase Date”) and shall contain such information concerning the business of the Company which the Company in good faith believes will enable such Holders to make an informed decision (which at a minimum shall include (1) the most recently filed Annual Report on Form 10-K (including audited consolidated financial statements) of the Company, the most recent subsequently filed Quarterly Report on Form 10-Q and any Current Report on Form 8-K of the Company filed subsequent to such Quarterly Report, other than Current Reports describing Asset Dispositions otherwise described in the offering materials (or corresponding successor reports); provided that in lieu of providing the reports specified in this subclause (1), the Company may, at its option, notify the holders that such reports are available to them in electronic format through the SEC’s EDGAR system, (2) a description of material developments in the Company’s business subsequent to the date of the latest of such reports, and (3) if material, appropriate pro forma financial information) and all instructions and materials necessary to tender Notes pursuant to the Offer, together with the address referred to in clause (iii).

(ii)                                  Not later than the date upon which written notice of an Offer is delivered to the Trustee as provided above, the Company shall deliver to the Trustee an Officers’ Certificate as to (1) the amount of the Offer (the “Offer Amount”), (2) the allocation of the Net Available Cash from the Asset Dispositions pursuant to which such Offer is being made and (3) the compliance of such allocation with the provisions of Section 3.09(a) and (b).  On the Business Day immediately preceding the Purchase Date, the Company shall irrevocably deposit with the Trustee or with a paying agent (or, if the Company is acting as its own paying agent, segregate and hold in trust) an amount equal to the Offer Amount to be invested in Temporary Cash Investments and to be held for payment in accordance with the provisions of this Section.  Upon the expiration of the period for which the Offer remains open (the “Offer Period”), the Company shall deliver to the Trustee for cancellation the Notes or portions thereof that have been properly tendered to and are to be accepted by the

46

Company.  The Trustee (or the Paying Agent, if not the Trustee) shall, on the Purchase Date, mail or deliver payment to each tendering Holder in the amount of the purchase price.  In the event that the Offer Amount delivered by the Company to the Trustee is greater than the purchase price of the Notes tendered, the Trustee shall deliver the excess to the Company promptly after the expiration of the Offer Period for application in accordance with this Section 3.09.

(iii)                               Holders electing to have a Note purchased shall be required to surrender the Note, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the Purchase Date.  Holders shall be entitled to withdraw their election if the Trustee or the Company receives not later than one Business Day prior to the Purchase Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note which was delivered by the Holder for purchase and a statement that such Holder is withdrawing his election to have such Note purchased.  If at the expiration of the Offer Period the aggregate principal amount of Notes surrendered by holders thereof plus the purchase price of other Senior Subordinated Indebtedness of the Company or the Subsidiary Guarantors being purchased or otherwise repaid exceeds the amount of Net Available Cash, the Company shall select the Notes and other Senior Subordinated Indebtedness to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Company so that only Notes and other Senior Subordinated Indebtedness in denominations of $2,000, or integral multiples of $1,000 in excess thereof, shall be purchased).  Holders whose Notes are purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered.

(iv)                              At the time the Company delivers Notes to the Trustee which are to be accepted for purchase, the Company shall also deliver an Officers’ Certificate stating that such Notes are to be accepted by the Company pursuant to and in accordance with the terms of this Section.  A Note shall be deemed to have been accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering Holder.

(v)                                 The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Securities Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 3.09.  To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 3.09, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 3.09 by virtue thereof.

47

SECTION 3.10                    Limitation on Transactions with Affiliates.

(a)                                  The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, enter into or conduct any transaction or series of related transactions (including, the purchase, sale, lease or exchange of any property or the rendering of any service) with any Affiliate of the Company (an “Affiliate Transaction”) unless such Affiliate Transaction is on terms (i) that are no less favorable to the Company or such Restricted Subsidiary, as the case may be, than those that could be obtained at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate, (ii) that, in the event such Affiliate Transaction involves an aggregate amount in excess of $20,000,000, (1)  are set forth in writing and (2)  have been approved by a majority of the members of the Board of Directors having no personal stake in such Affiliate Transaction, and (iii) that, in the event such Affiliate Transaction involves an amount in excess of $30,000,000, have been determined by a nationally recognized appraisal or investment banking firm to be fair, from a financial point of view, to the Company and its Restricted Subsidiaries.

(b)                                 The provisions of Section 3.10(a) shall not prohibit (i) any Permitted Investment or any Restricted Payment permitted to be paid pursuant to Section 3.07, (ii) any employment arrangements, employee benefit plans or arrangements (including pension plans, health and life insurance plans, retiree medical plans, deferred compensation plans, indemnification agreements, stock options and restricted stock and stock ownership plans) or related trust agreements or similar arrangements, in each case, approved by the Board of Directors and any grant or issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of any of the foregoing, (iii) loans or advances to employees in the ordinary course of business of the Company, but in any event not to exceed $5,000,000 in the aggregate outstanding at any one time, (iv) the payment of reasonable fees to directors of the Company or its Subsidiaries, (v) any transaction between the Company and a Restricted Subsidiary or between Restricted Subsidiaries, or (vi) the provision by Persons who may be deemed Affiliates of the Company of investment advisory services to the Company or its Restricted Subsidiaries with respect to the Company’s or its Restricted Subsidiaries’ employee benefit plans.

SECTION 3.11                    Change of Control. (a)                      Upon the occurrence of a Change of Control, each Holder will have the right to require the Company to purchase all or any part of such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, however, that notwithstanding the occurrence of a Change of Control, the Company shall not be obligated to purchase the Notes pursuant to this Section 3.11 in the event that it has exercised its right to redeem all the Notes, in accordance with the terms of Section 5 of the form of reverse of Note described in Section 2.02(b) of the Second Supplemental Indenture.  In the event that at the

48

time of such Change of Control the terms of the Bank Indebtedness restrict or prohibit the repurchase of Notes pursuant to this Section 3.11, then prior to the mailing of the notice to Holders provided for in Section 3.11(b) below but in any event within 45 days following any Change of Control, the Company shall (A) repay in full all Bank Indebtedness or, if doing so will allow the purchase of Notes, offer to repay in full all Bank Indebtedness and repay the Bank Indebtedness of each lender who has accepted such offer or (B) obtain the requisite consent under the agreements governing the Bank Indebtedness to permit the repurchase of the Notes as provided for in Section 3.11(b).

(b)                                 Within 45 days following any Change of Control, the Company shall mail a notice to each Holder with a copy to the Trustee (the “Change of Control Offer”) stating:

(i)                                     that a Change of Control has occurred and that such Holder has the right to require the Company to purchase all or a portion of such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest on the relevant interest payment date);

(ii)                                  the circumstances and relevant facts and financial information regarding such Change of Control;

(iii)                               the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed); and

(iv)                              the instructions determined by the Company, consistent with this Section 3.11, that a Holder must follow in order to have its Notes purchased.

(c)                                  Holders electing to have a Note purchased shall be required to surrender the Note, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the purchase date.  Holders shall be entitled to withdraw their election if the Trustee or the Company receives not later than one Business Day prior to the purchase date a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note which was delivered for purchase by the Holder and a statement that such Holder is withdrawing his election to have such Note purchased.  Holders whose Notes are purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered.

(d)                                 On the purchase date, all Notes purchased by the Company under this Section 3.11 shall be delivered to the Trustee for cancellation, and the Company shall pay the purchase price plus accrued and unpaid interest to the Holders entitled thereto.

(e)                                  Notwithstanding the foregoing provisions of this Section 3.11, the Company shall not be required to make 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 3.11(b) applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

(f)                                    At the time the Company delivers Notes to the Trustee which are to be accepted for purchase, the Company shall also deliver an Officers’ Certificate stating that such Notes are to be accepted by the Company pursuant to and in accordance with the terms of this Section 3.11.  A Note shall be deemed to have been accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering Holder.

(g)                                 Prior to any Change of Control Offer, the Company shall deliver to the Trustee an Officers’ Certificate stating that all conditions precedent contained herein to the right of the Company to make such offer have been complied with.

(h)                                 The Company will comply, to the extent applicable, with the requirements of Section 14(e) of the Securities Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section.  To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section by virtue thereof.

SECTION 3.12                    Further Instruments and Acts.  Upon request of the Trustee, the Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 3.13                    Future Subsidiary Guarantors.  The Company will cause each Restricted Subsidiary which guarantees any Indebtedness of the Company or any Domestic Subsidiary of the Company to become a Subsidiary Guarantor, and, if applicable, to execute and deliver to the Trustee a supplemental indenture substantially in the form of Appendix A to the Second Supplemental Indenture pursuant to which such Subsidiary will Guarantee payment of the Notes.  Each Subsidiary Guarantee will be limited to an amount not to exceed the maximum amount that can be Guaranteed by that Subsidiary Guarantor without rendering the Subsidiary Guarantee, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

SECTION 3.14                    Limitation on Lines of Business.  The Company shall not, and shall not permit any Restricted Subsidiary to, engage in any business, other than a Permitted Business.

50

SECTION 3.15                    Limitation on Senior Subordinated Debt.  The Company will not Incur any Indebtedness if such Indebtedness is subordinate or junior in ranking in any respect to any Senior Indebtedness unless such Indebtedness is Senior Subordinated Indebtedness or is expressly subordinated in right of payment to the Notes.  No Subsidiary Guarantor will Incur any Indebtedness if such Indebtedness is by its terms expressly subordinate or junior in ranking in any respect to any Senior Indebtedness of such Subsidiary Guarantor unless such Indebtedness is Senior Subordinated Indebtedness of such Subsidiary Guarantor or is expressly subordinated in right of payment to the Subsidiary Guarantee of such Subsidiary Guarantor.  For purposes of the foregoing, no Indebtedness will be deemed to be subordinated in right of payment to any other Indebtedness of the Company or any Subsidiary Guarantor, as applicable, solely by reason of any Liens or Guarantees arising or created in respect of such other Indebtedness of the Company or any Subsidiary Guarantor or by virtue of the fact that the holders of any Secured Indebtedness have entered into intercreditor agreements giving one or more of such holders priority over the other holders in the collateral held by them.

SECTION 3.16                    Limitation on Liens.  The Company will not Incur any Secured Indebtedness which is not Senior Indebtedness unless contemporaneously therewith effective provision is made to secure the Notes equally and ratably with (or on a senior basis to, in the case of Indebtedness subordinated in right of payment to the Notes) such Secured Indebtedness for so long as such Secured Indebtedness is secured by a Lien.  In addition, no Subsidiary Guarantor will Incur any Secured Indebtedness that is not Senior Indebtedness of such Subsidiary Guarantor unless contemporaneously therewith effective provision is made to secure the Subsidiary Guarantee of such Subsidiary Guarantor equally and ratably with (or on a senior basis to, in the case of Indebtedness subordinated in right of payment to such Subsidiary Guarantee) such Secured Indebtedness for as long as such Secured Indebtedness is secured by a Lien.

SECTION 3.17                    Covenant Suspension.

(a)                                  If on any date following the date hereof (i) the Notes are rated Baa3 or better by Moody’s and BBB- or better by S&P (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Company, the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Securities Exchange Act selected by the Company as a replacement agency) and (ii) no Default or Event of Default shall have occurred and be continuing, then, beginning on that day and subject to the provisions of subsection (c) below, and notwithstanding anything in this Article 3 to the contrary, the following covenants hereunder will be suspended:

(i)                                     Section 3.06;

(ii)                                  Section 3.07;

(iii)                               Section 3.08;

51

(iv)                              Section 3.09;

(v)                                 Section 3.10; and

(vi)                              Section 9.01(c).

(b)                                 During any period that the foregoing covenants have been suspended, the Board of Directors may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to the definition of “Unrestricted Subsidiary.”

(c)                                  Notwithstanding the foregoing, if the rating assigned by either such rating agency should subsequently decline to below Baa3 or BBB-, respectively, the foregoing covenants will be reinstituted as of and from the date of such rating decline. Calculations under the reinstated Section 3.07 will be made as if Section 3.07 had been in effect since the date of the Indenture, except that no Default will be deemed to have occurred solely by reason of a Restricted Payment made while that covenant was suspended. Also, any encumbrance or restriction of the type referred to in Section 3.08 incurred during the suspension period shall not result in a Default when such covenant is re-instituted.”

Section 3.04.                             Amendment of Article 4 of the Base Indenture.  Article 4 of the Base Indenture is hereby amended, subject to Section 3.01 hereof and, with respect to the Notes only, to delete Section 4.03 in its entirety and replace it with the following:

“SECTION 4.03.  Reports by the Company.  Unless otherwise specified as contemplated by Section 2.03 for the Securities of any Series, whether or not required by the Commission’s rules and regulations, the Company shall file with the Commission within the time periods specified in the Commission’s rules and regulations, and provide the Trustee and Holders and prospective Holders (upon request) within 15 days after it files them with the Commission, copies of its annual report and the information, documents and other reports that are specified in Sections 13 and 15(d) of the Securities Exchange Act, provided that for purposes of this covenant, such information, documents and other reports shall be deemed to have been furnished to the Trustee and Holders if they are electronically available via the Commission’s EDGAR System.  Even if the Company is entitled under the Securities Exchange Act not to furnish such information to the Commission, the Company shall nonetheless continue to furnish information that would be required to be furnished by the Company by Section 13 or 15(d) of the Securities Exchange Act (excluding exhibits) to the Trustee and the Holders of the Securities of any Series as if it were subject to such periodic reporting requirements.  The Company shall also comply with the other provisions of Section 314(a) of the Trust Indenture Act of 1939.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its

52

covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Notwithstanding anything herein to the contrary, the Issuer will not be deemed to have failed to comply with any of its obligations under this Section 4.03 for purposes of Section 5.01(e) until 90 days after the date any report under this Section 4.03 is due.”

Section 3.05.                             Amendment and Restatement of Section 5.01 of the Base Indenture.  Section 5.01 of the Base Indenture is hereby amended and restated in its entirety, subject to Section 3.01 hereof and, with respect to the Notes only, to read as follows:

(d)                                 the failure by the Company or any Restricted Subsidiary to comply for 45 days after notice with any of its obligations under Section 3.11 and Section 3.09 (in each case other than a failure to purchase Notes),

(e)                                  the failure by the Company or any Restricted Subsidiary to comply for 60 days after notice with its other agreements contained in the Notes or the Indenture,

(f)                                    the failure by the Company or any Subsidiary to pay any Indebtedness within any applicable grace period after final maturity or the acceleration of any such Indebtedness by the holders thereof because of a default if the total amount of such Indebtedness unpaid or accelerated exceeds $50,000,000 or its foreign currency equivalent and such failure continues for 10 days after receipt of the notice specified below,

(g)                                 the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

53

(i)                                     commences a voluntary case;

(ii)                                  consents to the entry of an order for relief against it in an involuntary case;

(iii)                               consents to the appointment of a Custodian of it or for any substantial part of its property; or

(i)                                     an enforcement proceeding thereon is commenced by any creditor or

(ii)                                  such judgment or decree remains outstanding for a period of 90 days following such judgment and is not paid, discharged, waived or stayed; or

54

Guarantor’s obligations under the indenture or any Subsidiary Guarantee and such Default continues for 10 days after receipt of the notice specified in the Indenture.

The term “Bankruptcy Law” means Title 11, UNITED STATES CODE, or any similar Federal or state law for the relief of debtors.  The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

A Default under clause (d), (e) or (f) will not constitute an Event of Default until the Trustee notifies the Company or the Holders of at least 25% in principal amount of the Notes then Outstanding notify the Company and the Trustee of the Default and the Company or the Subsidiary Guarantor, as applicable, does not cure such Default within the time specified in clause (d), (e) or (f) hereof after receipt of such notice.

If an Event of Default (other than an Event of Default under clause (g) or (h) with respect to the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes then Outstanding by notice to the Company may declare the principal of and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal and interest will be due and payable immediately. However, if any Designated Senior Indebtedness of the Company is outstanding, the Company may not pay the Notes until five Business Days after such holders or the Representative of such Designated Senior Indebtedness receives notice of such acceleration and, thereafter, may pay the Notes only if Article 13 otherwise permits payment at that time.

If an Event of Default relating to clause (g) or (h) with respect to the Company occurs, the principal of and interest on all the Notes will become immediately due and payable without any declaration or other act on the part of the trustee or any Holders. The Holders of a majority in principal amount of the Notes by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration.  No such rescission shall affect any subsequent Default or impair any right consequent thereto.”

Section 3.06.                             Amendment and Restatement of Article 8 of the Base Indenture.  Article 8 of the Base Indenture is hereby amended and restated in its entirety, subject to Section 3.01 hereof and, with respect to the Notes only, to read as follows:

“ARTICLE 8
AMENDMENT

SECTION 8.01.                 Amendments Without Consent of Holders.  The Company, the Subsidiary Guarantors and the Trustee may amend this Indenture or the Notes without notice to or consent of any Holder to:

55

(c)                                  add to the covenants of the Company and the Subsidiary Guarantors such further covenants, restrictions, conditions or provisions for the protection of the Holders of Notes;

(d)                                 cure any ambiguity or correct or supplement any provision contained in the Indenture that may be defective or inconsistent with any other provision contained in the Indenture, or make such other provisions in regard to matters or questions arising under the Indenture as the Board of Directors may deem necessary or desirable and that shall not materially and adversely affect the interests of the Holders of Notes;

(e)                                  evidence and provide for the acceptance of appointment under the Indenture by a successor trustee with respect to the Notes and add to or change any of the provisions of the Indenture as shall be necessary to provide for or facilitate the administration of the trusts under the Indenture by more than the one trustee pursuant to the requirements of the Indenture;

(f)                                    provide for uncertificated Notes in addition to or in place of certificated Notes (provided, however, that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code);

(g)                                 make any change in the subordination provisions of the Indenture that would limit or terminate the benefits available to any holder of Senior Indebtedness of the Company or a Subsidiary Guarantor (or any Representative thereof) under such subordination provisions;

56

Subsidiary Guarantor then outstanding unless the holders of such Senior Indebtedness (or any group or Representative thereof authorized to give a consent) consent to such change.

After an amendment under this Section 8.01 becomes effective, the Company shall mail to Holders a notice briefly describing such amendment.  The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 8.01

SECTION 8.02.                 Amendment with Consent of Holders.  The Indenture and the Notes may be amended with the written consent of the Holders of a majority in principal amount of the Notes then Outstanding and any past default or compliance with any provisions of the Indenture may be waived with the consent of the Holders of a majority in principal amount of the Notes then Outstanding (including consents obtained in connection with a tender offer or exchange for the Notes).  However, without the consent of each Holder affected, an amendment may not:

(g)                                 impair the right of any Holder to receive payment of principal of, and interest on, such Holder’s Notes on or after the due dates therefor or institute suit for the enforcement of any payment on or with respect to such Holder’s Notes,

(h)                                 make any change in this Article 8 which requires each Holder’s consent or in the waiver provisions or

(i)                                     modify any Subsidiary Guarantee in any manner materially adverse to the Holders.

It shall not be necessary for the consent of the Holders under this Section 8.02 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof.

57

An amendment under this Section 8.02 may not make any change that adversely affects the rights under Article 13 of the Indenture or Article 5 of the Second Supplemental Indenture of any holder of Senior Indebtedness then outstanding unless the holders of such Senior Indebtedness (or any group or Representative thereof authorized to give a consent) consent to such change.

After an amendment under this Section 8.02 becomes effective, the Company shall mail to Holders a notice briefly describing such amendment.  The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 8.02.

SECTION 8.03.                 Compliance With Trust Indenture Act.  Every amendment to this Indenture or the Notes shall comply with the TIA as then in effect.

SECTION 8.04.                 Revocation and Effect of Consents and Waivers.

(a)  A consent to an amendment or a waiver by a Holder of a Note shall bind the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent or waiver is not made on the Note.  However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustee receives the notice of revocation before the date on which the Trustee receives an Officers’ Certificate from the Company certifying that the requisite number of consents have been received.  After an amendment or waiver becomes effective, it shall bind every Holder.  An amendment or waiver becomes effective upon the (i) receipt by the Company or the Trustee of the requisite number of consents, (ii) satisfaction of conditions to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing such amendment or waiver and (iii) execution of such amendment or waiver (or supplemental indenture) by the Company and the Trustee.

(b)                                 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture.  If a record date is fixed, then notwithstanding Section 8.04(a), those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date.

SECTION  8.05.              Notation on or Exchange of Notes.  If an amendment changes the terms of a Note, the Trustee may require the Holder of the Note to deliver it to the Trustee.  The Trustee may place an appropriate notation on the Note regarding the changed terms and return it to the Holder.  Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms.  Failure to make the

58

appropriate notation or to issue a new Note shall not affect the validity of such amendment.

SECTION 8.06.                 Trustee to Sign Amendments.  The Trustee shall sign any amendment authorized pursuant to this Article 8 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee.  If, in the reasonable judgment of the Trustee, it does, the Trustee may but need not sign it.  In signing such amendment the Trustee shall receive indemnity reasonably satisfactory to it and receive, and (subject to Section 6.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture and that such amendment is the valid and binding obligation of the Company and the Subsidiary Guarantors enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof.

SECTION 8.07.                 Payment for Consent.  Neither the Company nor any Affiliate of the Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.”

Section 3.07.                             Amendment and Restatement of Article 9 of the Base Indenture.  Article 9 of the Base Indenture is hereby amended and restated in its entirety, subject to Section 3.01 hereof and, with respect to the Notes only, to read as follows:

(b)                                 Subject to Sections 10.01(c) and 10.02, the Company at any time may terminate (i) all of its obligations under the Notes and this Indenture (“legal defeasance option”) or (ii) its obligations under Sections 3.06, 3.07, 3.08, 3.09, 3.10, 3.11, 3.13, 3.14, 3.15, 3.16 and 4.03, the operation of Section 5.01(d), 5.01(e), 5.01(f), 5.01(g) (with respect to Significant Subsidiaries of the Company only), 5.01(h) (with respect to Significant Subsidiaries of the Company only), 5.01(i) (with respect to Restricted Subsidiaries of the Company only), 5.01(j), and 9.01(c) and (d) (“covenant defeasance option”).  The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.  In the event that the Company terminates all of its obligations under the Notes and this Indenture by exercising its legal defeasance option, the obligations under the Subsidiary Guarantees shall each be terminated simultaneously with the termination of such obligations.

If the Company exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default.  If the Company exercises its covenant defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in Section 5.01(d), 5.01(e), 5.01(f), 5.01(g) (with respect to Significant Subsidiaries of the Company only), 5.01(h) (with respect to Significant Subsidiaries of the Company only), 5.01(i) (with respect to Restricted Subsidiaries of the Company only), 5.01(j) or because of the failure of the Company to comply with Section 9.01(c) and (d).

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates.

(c)                                  Notwithstanding clauses (a) and (b) above, the Company’s obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 2.10, 3.02 and 6.07 and in this Article 10 shall survive until the Notes have been paid in full.  Thereafter, the Company’s obligations in Sections 6.07 and 10.05 and the Trustee’s obligations under Section 10.04 shall survive.”

(b)                                                                                 Section 10.02 of the Base Indenture is hereby amended, subject to Section 3.01 hereof and, with respect to the Notes only, to add the following after clause (iii) thereof:

“(iv)                        the deposit does not constitute a default under any other agreement binding on the Company and is not prohibited by Article 13 of the Indenture or Article 5 of the Second Supplemental Indenture;

(v)                                 the Company delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; and

(vi)                              the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities as contemplated by this Article 10 have been complied with.”

62

Section 3.09.                             Amendment and Restatement of Article 13 of the Base Indenture.  Article 13 of the Base Indenture is hereby amended and restated in its entirety, subject to Section 3.01 hereof and, with respect to the Notes only, to read as follows:

“ARTICLE 13
SUBORDINATION

SECTION 13.01.           Agreement to Subordinate.  The Company agrees, and each Holder by accepting a Note agrees, that the Indebtedness evidenced by the Notes is subordinated in right of payment, to the extent and in the manner provided in this Article 13, to the prior payment in full of all Senior Indebtedness of the Company and that the subordination is for the benefit of and enforceable by the holders of such Senior Indebtedness.  The Notes shall in all respects rank pari passu with all other Senior Subordinated Indebtedness of the Company and only Indebtedness of the Company that is Senior Indebtedness of the Company shall rank senior to the Notes in accordance with the provisions set forth herein.  All provisions of this Article 13 shall be subject to Section 13.12.

SECTION 13.02.           Liquidation, Dissolution, Bankruptcy.  Upon any payment or distribution of the assets of the Company to creditors upon a total or partial liquidation or a total or partial dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property:

(a)                                  holders of Senior Indebtedness of the Company will be entitled to receive payment in full in cash of such Senior Indebtedness before the Holders will be entitled to receive any payment of principal of or interest on the Notes; and

(b)                                 until the Senior Indebtedness of the Company is paid in full, any payment or distribution to which Holders would be entitled but for this Article 13 shall be made to holders of such Senior Indebtedness as their interests may appear, except that Holders may receive any debt securities that are subordinated to such Senior Indebtedness to at least the same extent as the Notes.

SECTION 13.03.           Default on Senior Indebtedness.  The Company may not pay the principal of, premium (if any) or interest on the Notes or make any deposit pursuant to Section 10.01 and may not otherwise purchase, repurchase, redeem or otherwise acquire or retire for value any Notes (collectively, “pay the Notes”) if (a) any Designated Senior Indebtedness of the Company is not paid when due or (b) any other default on Designated Senior Indebtedness of the Company occurs and the maturity of such Designated Senior Indebtedness is accelerated in accordance with its terms unless, in either case, (i) the default has been cured or waived and any such acceleration has been rescinded or (ii) such Designated Senior Indebtedness has been paid in full; provided, however, that the Company may pay the Notes without regard to the foregoing if the Company and the Trustee receive written notice approving such payment from the Representative of the Designated Senior Indebtedness with respect to which either of the

63

events set forth in clause (a) or (b) of this sentence has occurred and is continuing.  During the continuance of any default (other than a default described in clause (a) or (b) of the preceding sentence) with respect to any Designated Senior Indebtedness of the Company pursuant to which the maturity thereof may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, the Company may not pay the Notes for a period (a “Payment Blockage Period”) commencing upon the receipt by the Trustee (with a copy to the Company) of written notice (a “Blockage Notice”) of such default from the Representative of such Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period and ending 179 days thereafter (or earlier if such Payment Blockage Period is terminated (a) by written notice to the Trustee and the Company from the Person or Persons who gave such Blockage Notice, (b) by repayment in full of such Designated Senior Indebtedness or (c) because the default giving rise to such Blockage Notice is no longer continuing).  Notwithstanding the provisions described in the immediately preceding sentence (but subject to the provisions contained in the first sentence of this Section and the next sentence of this Section), unless the holders of such Designated Senior Indebtedness or the Representative of such holders shall have accelerated the maturity of such Designated Senior Indebtedness, the Company may resume payments on the Notes after the end of such Payment Blockage Period, including any missed payments.  Not more than one Blockage Notice may be given in any consecutive 360 day period, irrespective of the number of defaults with respect to Designated Senior Indebtedness during such period.  However, that if any Blockage Notice within such 360 day period is given by or on behalf of any holders of Designated Senior Indebtedness other than the Bank Indebtedness, the Representative of the Bank Indebtedness may give another Blockage Notice within such period.  In no event, however, may the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any 360 consecutive day period.  For purposes of this Section, no default or event of default that existed or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Designated Senior Indebtedness initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the Representative of such Designated Senior Indebtedness, whether or not within a period of 360 consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days.

SECTION 13.04.           Acceleration of Payment of Notes.  If payment of the Notes is accelerated because of an Event of Default, the Company or the Trustee (provided, that the Trustee shall have received written notice from the Company, on which notice the Trustee is entitled to conclusively rely) will promptly notify the holders of the Designated Senior Indebtedness of the Company (or their Representative) of the acceleration.  If any Designated Senior Indebtedness of the Company is outstanding, the Company may not pay the Notes until five Business Days after such holders or the Representative of such Designated Senior Indebtedness receive notice of such acceleration and, thereafter, may pay the Notes only if this Article 13 otherwise permits payment at that time.

64

SECTION 13.05.           When Distribution Must Be Paid Over.  If a distribution is made to Holders that because of this Article 13 should not have been made to them, the Holders who receive the distribution shall hold it in trust for holders of Senior Indebtedness of the Company and pay it over to them as their interests may appear.

SECTION 13.06.           Subrogation.  After all Senior Indebtedness of the Company is paid in full and until the Notes are paid in full, Holders shall be subrogated to the rights of holders of such Senior Indebtedness to receive distributions applicable to Senior Indebtedness.  A distribution made under this Article 13 to holders of such Senior Indebtedness which otherwise would have been made to Holders is not, as between the Company and Holders, a payment by the Company on such Senior Indebtedness.

SECTION 13.07.           Relative Rights.  This Article 13 defines the relative rights of Holders and holders of Senior Indebtedness of the Company.  Nothing in this Indenture shall:

(a)                                  impair, as between the Company and Holders, the obligation of the Company, which is absolute and unconditional, to pay principal of and interest on the Notes in accordance with their terms; or

(b)                                 prevent the Trustee or any Holder from exercising its available remedies upon a Default, subject to the rights of holders of Senior Indebtedness of the Company to receive distributions otherwise payable to Holders.

SECTION 13.08.           Subordination May Not Be Impaired by Company.  No right of any holder of Senior Indebtedness of the Company to enforce the subordination of the Indebtedness evidenced by the Notes shall be impaired by any act or failure to act by the Company or by its failure to comply with this Indenture.

SECTION 13.09.           Rights of Trustee and Paying Agent.  Notwithstanding Section 13.03, the Trustee or Paying Agent may continue to make payments on the Notes and shall not be charged with knowledge of the existence of facts that would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, a Trust Officer of the Trustee receives notice satisfactory to it that payments may not be made under this Article 13.  The Company, the Registrar, the Paying Agent, a Representative or a holder of Senior Indebtedness of the Company may give the notice; provided, however, that, if an issue of Senior Indebtedness of the Company has a Representative, only the Representative may give the notice.

The Trustee in its individual or any other capacity may hold Senior Indebtedness of the Company with the same rights it would have if it were not Trustee.  The Registrar and the Paying Agent may do the same with like rights.  The Trustee shall be entitled to all the rights set forth in this Article 13 with respect to any Senior Indebtedness of the Company which may at any time be held by it, to the same extent as any other holder of such Senior Indebtedness; and nothing in Article 6 shall deprive the Trustee of any of its

65

rights as such holder.  Nothing in this Article 13 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.07 or any other Section of this Indenture.

SECTION 13.10.           Distribution or Notice to Representative.  Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness of the Company, the distribution may be made and the notice given to their Representative (if any).

SECTION 13.11.           Article 13 Not to Prevent Events of Default or Limit Right to Accelerate.  The failure to make a payment pursuant to the Notes by reason of any provision in this Article 13 shall not be construed as preventing the occurrence of a Default.  Nothing in this Article 13 shall have any effect on the right of the Holders or the Trustee to accelerate the maturity of the Notes.

SECTION 13.12.           Trust Monies Not Subordinated.  Notwithstanding anything contained herein to the contrary, payments from money or the proceeds of U.S. Government Obligations held in trust under Article 10 by the Trustee for the payment of principal of and interest on the Notes shall not be subordinated to the prior payment of any Senior Indebtedness of the Company or subject to the restrictions set forth in this Article 13, and none of the Holders shall be obligated to pay over any such amount to the Company or any holder of Senior Indebtedness of the Company or any other creditor of the Company.

SECTION 13.13.           Trustee Entitled to Rely.  Upon any payment or distribution pursuant to this Article 13, the Trustee and the Holders shall be entitled to conclusively rely (a) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 13.02 are pending, (b) upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to the Holders or (c) upon the Representatives for the holders of Senior Indebtedness of the Company for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of such Senior Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 13.  In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of the Company to participate in any payment or distribution pursuant to this Article 13, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article 13, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment.  The provisions of Sections 6.01 and 6.02 shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article 13.

SECTION 13.14.           Trustee to Effectuate Subordination.  Each Holder by accepting a Note authorizes and directs the Trustee on his behalf to take such action as

66

may be necessary or appropriate to acknowledge or effectuate the subordination between the Holders and the holders of Senior Indebtedness of the Company as provided in this Article 13 and appoints the Trustee as attorney-in-fact for any and all such purposes.

SECTION 13.15.           Trustee Not Fiduciary for Holders of Senior Indebtedness.  The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of the Company and shall not be liable to any such holders if it shall mistakenly pay over or distribute to Holders or the Company or any other Person, money or assets to which any holders of Senior Indebtedness of the Company shall be entitled by virtue of this Article 13 or otherwise.

SECTION 13.16.           Reliance by Holders of Senior Indebtedness on Subordination Provisions.  Each Holder by accepting a Note acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Indebtedness of the Company, whether such Senior Indebtedness was created or acquired before or after the issuance of the Notes, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness and such holder of such Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness.”

Section 3.10.                             Amendment of Article 14 of the Base Indenture.  Article 14 of the Base Indenture is hereby amended by amending and restating Sections 14.01, 14.04 and 14.06, and by adding the following Sections 14.13, 14.14, and 14.15, each subject to Section 3.01 hereof and, with respect to the Notes only, as follows:

“SECTION 14.01.  Incorporators, Shareholders, Officers and Directors of Company Exempt from Individual Liability.  No director, officer, employee, incorporator, stockholder, member, manager or partner of the Company or any Subsidiary Guarantor, as such, will have any liability for any obligations of the Company or the Subsidiary Guarantors under the Notes, the Indenture, the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation.  Each Holder of Notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration.

SECTION 14.04.  Notices.  Any notice or communication shall be in writing and delivered in person or mailed by first-class mail or facsimile with receipt confirmed addressed as follows:

Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders.  If a notice or communication is mailed in the manner provided above, it is duly given, whether or not the addressee receives it.

The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission or other similar unsecured electronic methods, provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing.  If the Issuer elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling.

The Issuer agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties.

SECTION 14.06. Payments Due on Legal Holidays.  Unless otherwise specified in a Note, if the date of maturity of interest on or principal or premium, if any, of the Notes or the date fixed for redemption, repurchase or repayment of any Note shall be a Legal Holiday, payment of interest or principal or premium, if any, need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the date of maturity or the date fixed for redemption, and no interest shall accrue for the period after such date.  If a regular record date is a Legal Holiday, the record date shall not be affected.

SECTION 14.13.  Communication by Holders With Other Holders.  Holders may communicate pursuant to Section 312(b) of the TIA with other Holders with respect to their rights under this Indenture or the Securities.  The Company, the Trustee, the Registrar and anyone else shall have the protection of Section 312(c) of the TIA.

68

SECTION 14.14.  When Securities Disregarded.  In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company, any Subsidiary Guarantor or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Subsidiary Guarantor shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which a Trust Officer actually knows are so owned shall be so disregarded.  Subject to the foregoing, only Securities outstanding at the time shall be considered in any such determination.

SECTION 14.15.  Rules by Trustee, Paying Agent and Registrar.  The Trustee may make reasonable rules for action by or a meeting of Holders.  The Registrar and the Paying Agent may make reasonable rules for their functions.”

ARTICLE 4
SUBSIDIARY GUARANTEES

Section 4.01.                             Subsidiary Guarantees.  (a)  Each Subsidiary Guarantor hereby jointly and severally irrevocably and unconditionally guarantees, as a primary obligor and not merely as a surety, to each Holder and to the Trustee and its successors and assigns (i) the full and punctual payment when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, of all obligations of the Company under this Indenture (including obligations to the Trustee) and the Notes, whether for payment of principal of, or premium or interest on the Notes and all other monetary obligations of the Company under this Indenture and the Notes and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Company whether for fees, expenses, indemnification or otherwise under this Indenture and the Notes (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”).  Each Subsidiary Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from each such Subsidiary Guarantor, and that each such Subsidiary Guarantor shall remain bound under this Article 4 notwithstanding any extension or renewal of any Guaranteed Obligation.

(b)                                 Each Subsidiary Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment.  Each Subsidiary Guarantor waives notice of any Default under the Notes or the Guaranteed Obligations.  The obligations of each Subsidiary Guarantor hereunder shall not be affected by (i) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Notes or any other agreement or otherwise; (ii) any extension or renewal of any thereof; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (iv) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (v) the failure of any Holder or Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (vi) any change in the ownership of such Subsidiary Guarantor, except as provided in Section 4.02(b) of the Second Supplemental Indenture.

69

(c)                                  Each Subsidiary Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided among the Subsidiary Guarantors, such that such Subsidiary Guarantor’s obligations would be less than the full amount claimed.  Each Subsidiary Guarantor hereby waives any right to which it may be entitled to have the assets of the Company first be used and depleted as payment of the Company’s or such Subsidiary Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Subsidiary Guarantor hereunder.  Each Subsidiary Guarantor hereby waives any right to which it may be entitled to require that the Company be sued prior to an action being initiated against such Subsidiary Guarantor.

(d)                                 Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations.

(e)                                  The Subsidiary Guarantee of each Subsidiary Guarantor is, to the extent and in the manner set forth in Article 5 of the Second Supplemental Indenture, subordinated and subject in right of payment to the prior payment in full of the principal of and premium, if any, and interest on all Senior Indebtedness of the relevant Subsidiary Guarantor and is made subject to such provisions of this Indenture.

(f)                                    Except as expressly set forth in Section 10.01(b) of the Indenture and Sections 4.02 and 4.06 of the Second Supplemental Indenture, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise.  Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Subsidiary Guarantor or would otherwise operate as a discharge of any Subsidiary Guarantor as a matter of law or equity.

(g)                                 Except as otherwise provided herein, each Subsidiary Guarantor agrees that its Subsidiary Guarantee shall remain in full force and effect until payment in full of all the Guaranteed Obligations.  Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

(h)                                 In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any

70

Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (iii) all other monetary obligations of the Company to the Holders and the Trustee.

(i)                                     Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations and all obligations to which the Guaranteed Obligations are subordinated as provided in Article 5 of the Second Supplemental Indenture.  Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 5 of the Indenture for the purposes of any Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 5 of the Indenture, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Subsidiary Guarantor for the purposes of this Section 4.01.

(j)                                     Each Subsidiary Guarantor also agrees to pay any and all costs and expenses (including reasonable attorney’s fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 4.01.

(k)                                  Upon request of the Trustee, each Subsidiary Guarantor shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

Section 4.02.                             Limitation on Liability.  (a)  Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.(b)  A Subsidiary Guarantee as to any Subsidiary Guarantor shall terminate and be of no further force or effect and such Subsidiary Guarantor shall be deemed to be released from all obligations under this Article 4 upon (i) the sale by the Company or a Restricted Subsidiary of the Capital Stock of such Subsidiary Guarantor in compliance with Section 3.09 of the Indenture, if as a result of such sale, such Subsidiary Guarantor ceases to be a Restricted Subsidiary, (ii) the designation of any Subsidiary Guarantor to be an Unrestricted Subsidiary in compliance with the definition of “Unrestricted Subsidiary”, (iii) legal defeasance or covenant defeasance or satisfaction and discharge of the Notes in compliance with the provisions of Article 10 of the Indenture, or (iv) the release of such Subsidiary Guarantor from its guarantee of all Indebtedness of the Company and all Domestic Subsidiaries.

71

(c)                                  At the request of the Company, the Trustee shall execute and deliver an appropriate instrument, in the form provided by the Company, evidencing the release of any Subsidiary Guarantor pursuant to Section 4.02(b) of the Second Supplemental Indenture.

Section 4.03.                             Successors and Assigns.  Subject to Article 9, this Article 4 shall be binding upon each Subsidiary Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

Section 4.04.                             No Waiver.  Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 4 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege.  The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 4 at law, in equity, by statute or otherwise.

Section 4.05.                             Modification.  No modification, amendment or waiver of any provision of this Article 4, nor the consent to any departure by any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.  No notice to or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances.

Section 4.06.                             Execution of Supplemental Indenture for Future Subsidiary Guarantors.   Each Subsidiary which is required to become a Subsidiary Guarantor pursuant to Section 3.13, shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Appendix A hereto pursuant to which such Subsidiary shall become a Subsidiary Guarantor under this Article 4 and shall guarantee the Guaranteed Obligations.  Concurrently with the execution and delivery of such supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Subsidiary Guarantee of such Subsidiary Guarantor is a valid and binding obligation of such Subsidiary Guarantor, enforceable against such Subsidiary Guarantor in accordance with its terms and as to such other matters as the Trustee may reasonably request.

Section 4.07.                             Non-Impairment.  The failure to endorse a Subsidiary Guarantee on any Note shall not affect or impair the validity thereof.

ARTICLE 5
SUBORDINATION OF THE SUBSIDIARY GUARANTEES

Section 5.01.                             Agreement to Subordinate.  Each Subsidiary Guarantor agrees, and each Holder by accepting a Note agrees, that the obligations of a Subsidiary Guarantor hereunder are subordinated in right of payment, to the extent and in the manner provided in this Article 5, to the prior payment in full of all Senior Indebtedness of such Subsidiary Guarantor and that the subordination is for the benefit of and enforceable by the holders of such Senior Indebtedness of such Subsidiary Guarantor.  The obligations hereunder with respect to a Subsidiary Guarantor shall in all respects rank pari passu with all other Senior Subordinated Indebtedness of such Subsidiary Guarantor and shall rank senior to all existing and future Subordinated Obligations of such Subsidiary Guarantor; and only Indebtedness of such Subsidiary Guarantor that is Senior Indebtedness of such Subsidiary Guarantor shall rank senior to the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee in accordance with the provisions set forth herein.

Section 5.02.                             Liquidation, Dissolution, Bankruptcy.  Upon any payment or distribution of the assets of a Subsidiary Guarantor to creditors upon a total or partial liquidation or a total or partial dissolution of such Subsidiary Guarantor or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to such Subsidiary Guarantor or its property:

(a)                                  holders of Senior Indebtedness of such Subsidiary Guarantor shall be entitled to receive payment in full in cash of such Senior Indebtedness before Holders shall be entitled to receive any payment pursuant to any Guaranteed Obligations from such Subsidiary Guarantor; and

(b)                                 until the Senior Indebtedness of such Subsidiary Guarantor is paid in full, any payment or distribution to which Holders would be entitled but for this Article 5 shall be made to holders of such Senior Indebtedness as their respective interests may appear, except that Holders may receive any debt securities that are subordinated to such Senior Indebtedness to at least the same extent as the Subsidiary Guarantees.

Section 5.03.                             Default on Designated Senior Indebtedness of a Subsidiary Guarantor.  A Subsidiary Guarantor may not make any payment pursuant to any of the Guaranteed Obligations or purchase, repurchase, redeem or otherwise acquire or retire for value any Securities (collectively, “pay its Guarantee”) if (a) any Designated Senior Indebtedness of such Subsidiary Guarantor is not paid when due or (b) any other default on Designated Senior Indebtedness of such Subsidiary Guarantor occurs and the maturity of such Designated Senior Indebtedness is accelerated in accordance with its terms unless, in either case, (i) the default has been cured or waived and any such acceleration has been rescinded or (ii) such Designated Senior Indebtedness has been paid in full; provided, however, that such Subsidiary Guarantor may pay its Guarantee without regard to the foregoing if such Subsidiary Guarantor and the Trustee receive written notice approving such payment from the Representative of the holders of the Designated Senior Indebtedness with respect to which either of the events in clause (a) or (b) of this sentence has occurred and is continuing.  During the continuance of any default (other than a default described in clause (a) or (b) of the preceding sentence) with respect to any Designated Senior Indebtedness of a Subsidiary Guarantor pursuant to which the maturity

73

thereof may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, such Subsidiary Guarantor may not pay its Guarantee for a period (a “Guarantee Payment Blockage Period”) commencing upon the receipt by the Trustee (with a copy to such Subsidiary Guarantor and the Company) of written notice (a “Guarantee Blockage Notice”) of such default from the Representative of the holders of the Designated Senior Indebtedness of such Subsidiary Guarantor specifying an election to effect a Guarantee Payment Blockage Period and ending 179 days thereafter (or earlier if such Guarantee Payment Blockage Period is terminated (a) by written notice to the Trustee (with a copy to such Subsidiary Guarantor and the Company) from the Person or Persons who gave such Guarantee Blockage Notice, (b) because such Designated Senior Indebtedness has been repaid in full or (c) because the default giving rise to such Guarantee Blockage Notice is no longer continuing).  Notwithstanding the provisions described in the immediately preceding sentence (but subject to the provisions contained in the first sentence of this Section 5.03 and the next sentence of this Section 5.03), unless the holders of such Designated Senior Indebtedness or the Representative of such holders shall have accelerated the maturity of such Designated Senior Indebtedness, such Subsidiary Guarantor may resume to paying its Subsidiary Guarantee after such Guarantee Payment Blockage Period, including any missed payments.  Not more than one Guarantee Blockage Notice may be given with respect to a Subsidiary Guarantor in any consecutive 360-day period, irrespective of the number of defaults with respect to Designated Senior Indebtedness of such Subsidiary Guarantor during such period; provided, however, that if any Guarantee Blockage Notice within such 360-day period is given by or on behalf of any holders of Designated Senior Indebtedness of such Subsidiary Guarantor other than the Bank Indebtedness, the Representative of the Bank Indebtedness may give another Guarantee Blockage Notice within such period; provided further, however, that in no event may the total number of days during which any Guarantee Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any 360 consecutive day period.  For purposes of this Section 5.03, no default or event of default that existed or was continuing on the date of the commencement of any Guarantee Payment Blockage Period with respect to the Designated Senior Indebtedness initiating such Guarantee Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Guarantee Payment Blockage Period by the Representative of such Designated Senior Indebtedness, whether or not within a period of 360 consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days.

Section 5.04.                             Demand for Payment.  If payment of the Notes is accelerated because of an Event of Default and a demand for payment is made on a Subsidiary Guarantor pursuant to Article 4, the Trustee (provided that the Trustee shall have received written notice from the Company or such Subsidiary Guarantor, on which notice the Trustee shall be entitled to conclusively rely) shall promptly notify the holders of the Designated Senior Indebtedness of such Subsidiary Guarantor (or the Representative of such holders) of such demand.  If any Designated Senior Indebtedness of such Subsidiary Guarantor is outstanding, such Subsidiary Guarantor may not pay its Guarantee until five Business Days after such holders or the Representative of the holders of the Designated Senior Indebtedness of such Subsidiary Guarantor receive notice of such demand and, thereafter, may pay its Guarantee only if this Article 5 otherwise permits payment at that time.

74

Section 5.05.                          When Distribution Must Be Paid Over.  If a payment or distribution is made to Holders that because of this Article 5 should not have been made to them, the Holders who receive the payment or distribution shall hold such payment or distribution in trust for holders of the Senior Indebtedness of the relevant Subsidiary Guarantor and pay it over to them as their respective interests may appear.

Section 5.06.                          Subrogation.  After all Senior Indebtedness of a Subsidiary Guarantor is paid in full and until the Notes are paid in full in cash, Holders shall be subrogated to the rights of holders of Senior Indebtedness of such Subsidiary Guarantor to receive distributions applicable to Senior Indebtedness of such Subsidiary Guarantor.  A distribution made under this Article 5 to holders of Senior Indebtedness of such Subsidiary Guarantor which otherwise would have been made to Holders is not, as between such Subsidiary Guarantor and Holders, a payment by such Subsidiary Guarantor on Senior Indebtedness of such Subsidiary Guarantor.

Section 5.07.                          Relative Rights.  This Article 5 defines the relative rights of Holders and holders of Senior Indebtedness of a Subsidiary Guarantor.  Nothing in this Indenture shall:

(a)                                 impair, as between a Subsidiary Guarantor and Holders, the obligation of a Subsidiary Guarantor which is absolute and unconditional, to make payments with respect to the Guaranteed Obligations to the extent set forth in Article 4 of the Second Supplemental Indenture; or

(b)                                 prevent the Trustee or any Holder from exercising its available remedies upon a Default by a Subsidiary Guarantor under its obligations with respect to the Guaranteed Obligations, subject to the rights of holders of Senior Indebtedness of such Subsidiary Guarantor to receive distributions otherwise payable to Holders.

Section 5.08.                          Subordination May Not Be Impaired by a Subsidiary Guarantor.  No right of any holder of Senior Indebtedness of a Subsidiary Guarantor to enforce the subordination of the obligations of such Subsidiary Guarantor hereunder shall be impaired by any act or failure to act by such Subsidiary Guarantor or by its failure to comply with this Indenture.

Section 5.09.                          Rights of Trustee and Paying Agent.  Notwithstanding Section 5.03 of the Second Supplemental Indenture, the Trustee or the Paying Agent may continue to make payments on the Notes and shall not be charged with knowledge of the existence of facts that would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, a Trust Officer of the Trustee receives notice satisfactory to it that payments may not be made under this Article 5.  A Subsidiary Guarantor, the Registrar, the Paying Agent, a Representative or a holder of Senior Indebtedness of a Subsidiary Guarantor may give the notice; provided, however, that if an issue of Senior Indebtedness of a Subsidiary Guarantor has a Representative, only the Representative may give the notice.

The Trustee in its individual or any other capacity may hold Senior Indebtedness of a Subsidiary Guarantor with the same rights it would have if it were not Trustee.  The

75

Registrar and the Paying Agent may do the same with like rights.  The Trustee shall be entitled to all the rights set forth in this Article 5 with respect to any Senior Indebtedness of a Subsidiary Guarantor which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness of such Subsidiary Guarantor; and nothing in Article 6 of the Indenture shall deprive the Trustee of any of its rights as such holder.  Nothing in this Article 5 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.07 of this Indenture or any other Section of this Indenture.

Section 5.10.                          Distribution or Notice to Representative.  Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness of a Subsidiary Guarantor, the distribution may be made and the notice given to their Representative (if any).

Section 5.11.                          Article 5 Not to Prevent Events of Default or Limit Right to Accelerate.  The failure of a Subsidiary Guarantor to make a payment on any of its obligations by reason of any provision in this Article 5 shall not be construed as preventing the occurrence of a default by such Subsidiary Guarantor under such obligations.  Nothing in this Article 5 shall have any effect on the right of the Holders or the Trustee to make a demand for payment on a Subsidiary Guarantor pursuant to Article 5 of the Second Supplemental Indenture.

Section 5.12.                          Trustee Entitled to Rely.  Upon any payment or distribution pursuant to this Article 5, the Trustee and the Holders shall be entitled to conclusively rely (a) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 5.02 of the Second Supplemental Indenture are pending, (b) upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to the Holders or (c) upon the Representatives for the holders of Senior Indebtedness of a Subsidiary Guarantor for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness of a Subsidiary Guarantor and other Indebtedness of a Subsidiary Guarantor, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 5.  In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of a Subsidiary Guarantor to participate in any payment or distribution pursuant to this Article 5, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness of such Subsidiary Guarantor held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article 5, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment.  The provisions of Sections 6.01 and 6.02 of this Indenture shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article 5.

Section 5.13.                          Trustee to Effectuate Subordination.  Each Holder by accepting a Note authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination between the Holders and the holders of Senior Indebtedness of each of the Subsidiary Guarantors as provided in this Article 5 and appoints the Trustee as attorney-in-fact for any and all such purposes.

76

Section 5.14.                          Trustee Not Fiduciary for Holders of Senior Indebtedness of a Subsidiary Guarantor.  The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of a Subsidiary Guarantor and shall not be liable to any such holders if it shall mistakenly pay over or distribute to Holders or the relevant Subsidiary Guarantor or any other Person, money or assets to which any holders of Senior Indebtedness of such Subsidiary Guarantor shall be entitled by virtue of this Article 5 or otherwise.

Section 5.15.                          Reliance by Holders of Senior Indebtedness of a Subsidiary Guarantor on Subordination Provisions.  Each Holder by accepting a Note acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Indebtedness of a Subsidiary Guarantor, whether such Senior Indebtedness was created or acquired before or after the issuance of the Notes, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness.

Section 5.16.                          Defeasance.  Notwithstanding anything contained herein to the contrary, payments from money or the proceeds of U.S. Government Obligations held in trust under Article 10 of the Indenture by the Trustee for the payment of principal of, and interest on, the Notes shall not be subordinated to the prior payment of any Senior Indebtedness of any Subsidiary Guarantor or subject to the restrictions set forth in this Article 5, and none of the Holders shall be obligated to pay over any such amount to a Subsidiary Guarantor or any holder of Senior Indebtedness of Subsidiary Guarantor or any other creditor of a Subsidiary Guarantor.

ARTICLE 6
MISCELLANEOUS PROVISIONS

Section 6.01.                          Governing Law.  THE SECOND SUPPLEMENTAL INDENTURE AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

Section 6.02.                          Successors and Assigns of Company Bound by Indenture.  All the covenants, stipulations, promises and agreements in the Second Supplemental Indenture contained by or on behalf of the Company shall bind its successors and assigns, whether so expressed or not.

Section 6.03.                          Counterparts.  The Second Supplemental Indenture may be executed in any number of counterparts, each of which shall be an original; but such counterparts shall together constitute but one and the same instrument.

Section 6.04.                          Conflict of any Provision of Indenture with Trust Indenture Act.  If any provision of the Second Supplemental Indenture limits, qualifies or conflicts with another provision of the Indenture that is required to be included by the TIA, as in force at the date the Second Supplemental Indenture is executed, the provision required by the TIA shall control.

Section 6.05.                          Consent to Jurisdiction.  Any legal suit, action or proceeding arising out of or based upon the Indenture, the Second Supplemental Indenture, the Notes or any
