The following provisions shall apply with respect to the registration of any proposed transfer of an Initial Security to a QIB and transfers to or by Non-U.S. Persons: (i) The Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Initial Security stating, or has otherwise advised the Company and the Registrar in writing sub stantially in the form of Exhibit C hereto, that the sale has been made in compliance with the provisions of Rule 144A to a transfer ee who has signed the certification provided for on the form of Initial Security stating, or has otherwise advised the Company and the Registrar in writing, that it is purchasing the Initial Security for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as it has request ed pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A. (ii) The Registrar shall register the transfer of any Initial Security if the proposed transferee is a Non-U.S. Person and the proposed transferor has delivered to the Registrar a certificate substantially in the form of Exhibit D hereto. (b) Private Placement Legend. Upon the transfer, ex change or replacement of Securities not bearing the Private Placement Legend, the Registrar shall deliver Securities that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Securities bearing the Private Placement Legend, the Registrar shall deliver only Securities that bear the Private Placement Legend unless there is delivered to the Registrar an opinion of counsel reasonably satisfactory to the Company and the Registrar to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. (c) General. By its acceptance of any Security bearing the Private Placement Legend, each holder of such Security acknowledges the restrictions on transfer of such Security set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Security only as provided in this Indenture. The Registrar shall not register a transfer of any Security unless such transfer complies with the restrictions on transfer of such Security set forth in this Indenture, provided, however, that the Registrar shall register the transfer of any Initial Security, whether or not such Initial Security bears the Private Placement Legend, if the requested transfer is at least two years after the later of the original Issue Date of the Initial Security and the last date on which such Initial Security was held by an affiliate of the Company. In connection with any transfer of Securities, each holder agrees by its acceptance of the Initial Securities to furnish the Registrar or the Company such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act; provided that the Registrar shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other information. The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.7 hereof or this Section 2.8. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar. SECTION 2.9 Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrong fully taken and the Holder furnishes to the Company and the Trustee evidence to their satisfaction of such loss, destruction or wrongful taking, the Company shall issue and the Trustee shall, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, authenti cate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met (and the Registrar shall be entitled to assume such requirements have been met unless it receives written notice to the contrary) and if there is delivered to the Company and the Trustee such security or indemnity as may be required to save each of them harmless, satisfactory to the Company or the Trustee, as the case may be. The Company and the Trustee may charge the Holder for their expenses in replacing a Security. Every replacement Security is an additional obligation of the Company and shall be entitled to the benefits of this Indenture. SECTION 2.10 Outstanding Securities. The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, and those described in this Section as not outstanding. If a Security is replaced pursuant to Section 2.9, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser. If all the principal and interest on any Securities are considered paid under Section 3.1, such Securities cease to be outstanding under this Inden ture and interest on such Securities shall cease to accrue. If the Paying Agent (other than the Company or a Subsidiary or an Affiliate of the Company) holds in accordance with this Indenture on a redemp tion date or maturity date money sufficient to pay all principal and interest due on that date then on and after that date such Securities cease to be outstanding and interest on them ceases to accrue (unless there shall be a default in such pay ment). If a Security is called for redemption, the Company and the Trustee need not treat the Security as outstanding in determining whether Holders of the required principal amount of Securities have concurred in any direction, waiver or consent. Subject to Section 2.11, a Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security. SECTION 2.11 Determination of Holders' Action. In determining whether the Holders of the required principal amount of Securities have concurred in any direction, amendment, waiver or consent, Securities owned by or pledged to the Company, any other obligor upon the Securities or any Affiliate of the Company, or such other obligor shall be disregarded and deemed not to be outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee knows are so owned or pledged shall be so disregarded. SECTION 2.12 Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee, upon the written order of the Company signed by two Officers, shall authenticate definitive Securities in exchange for temporary Securities. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so ex changed, temporary Securities shall be entitled to the same rights, benefits and privileges as definitive Securities. SECTION 2.13 Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and shall return such cancelled securities to the Company. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. SECTION 2.14 Defaulted Interest. If the Company defaults in a payment of interest on the Securities, it shall pay defaulted interest, plus any interest payable on the defaulted interest to the extent permitted by law, in any lawful manner. It may pay the defaulted interest to the Persons who are Securityholders on a subsequent special record date which date shall be at least five Business Days prior to the payment date. The Company shall fix the special record date and payment date. At least 15 days before the special record date, the Company (or the Trustee, in the name of and at the expense of the Company) shall mail to Securityholders a notice that states the special record date, payment date and amount of interest to be paid. ARTICLE III COVENANTS SECTION 3.1 Payment of Securities. The Company shall pay the principal of and interest on the Securi ties on the dates and in the manner provided in the Securities. The Company shall pay interest on overdue principal at the rate borne by the Securities; it shall pay interest on overdue installments of interest at the rate borne by the Securities to the extent lawful. Principal and interest shall be considered paid on the date due (including a redemption date) if the Trustee or the Paying Agent (other than the Company or a Subsidiary or an Affiliate of the Company) has received from or on behalf of the Company on or prior to 11:00 a.m., eastern standard time, on that date, in immediately available funds, money sufficient to pay all principal and interest then due. SECTION 3.2 Maintenance of Office or Agency. The Company shall maintain in the Borough of Manhattan, the City of New York, an office or agency where Securities may be surrendered for registration of transfer or exchange or for presentation for payment and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 10.2 of this Indenture. The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designa tions; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, the City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agen cy. SECTION 3.3 Limitation on Restricted Payments. (a) So long as any of the Securities are outstanding, the Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, (i) declare or pay any dividend on or make any distribution or similar payment of any sort in respect of its Capital Stock (including any payment in connection with any merger or consolidation involving the Company) to the direct or indirect holders of its Capital Stock (other than dividends or distributions payable solely in its Non-Convertible Capital Stock or rights to acquire its Non-Convertible Capital Stock and dividends or distributions payable solely to the Company or a Restricted Subsidiary and other than pro rata dividends paid by a Subsidiary with respect to a series or class of its Capital Stock the majority of which is held by the Company or a Wholly Owned Subsidiary that is not a Foreign Subsidiary), (ii) purchase, redeem, defease or otherwise acquire or retire for value any Capital Stock of the Company or of any direct or indirect parent of the Company, or, with respect to the Company, exercise any option to exchange any Capital Stock that by its terms is exchangeable solely at the option of the Company (other than into Capital Stock of the Company which is neither Exchangeable Stock nor Redeemable Stock), (iii) purchase, repurchase, redeem, defease or otherwise ac quire or retire for value, prior to scheduled maturity or scheduled repayment thereof or scheduled sinking fund payment thereon, any Subordinated Indebted ness (other than the purchase, repurchase or other acquisition of Subordinated Indebtedness purchased 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 Controlled Non- Subsidiary Investment or a payment described in clause (vi) of the second sentence of Section 3.11, in any Unrestricted Subsidiary or any Affiliate of the Company other than a Restricted Subsidiary or a Person which will become a Restricted Subsidiary as a result of any such Investment (each such payment de scribed in clauses (i)-(iv) of this paragraph, a "Restricted Payment"), unless at the time of and after giving effect to the proposed Restricted Payment: (1) no Default or Event of Default shall have occurred and be continuing (or would result therefrom);

(E) an amount equal to the net reduction in Investments in Unre stricted Subsidiaries resulting from payments of interest on Indebtedness, dividends, repayments of loans or advances, or other transfers of assets, in each case to the Company or any Restricted Subsidiary from Unrestricted Subsidiaries, or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each case as provided in the definition of "Investments"), not to exceed in the case of any Unrestricted Subsidiary the amount of Investments previously made by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary;

SECTION 3.12 Sales of Assets. (a) Neither the Company nor any Restricted Subsidiary shall consummate any Asset Sale unless (i) the Company or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the fair market value, as determined in good faith by the Board of Directors, of the shares or assets subject to such Asset Sale, (ii) at least 60% of the consideration thereof received by the Company or such Restricted Subsidiary is in the form of cash or cash equivalents which are promptly converted into cash by the Person receiving such payment and (iii) an amount equal to 100% of the Net Available Cash is applied by the Company (or such Subsidiary, as the case may be) as set forth herein. The Company shall not permit any Unrestricted Subsidiary to make any Asset Sale unless such Unrestricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the fair market value of the shares or assets so disposed of as determined in good faith by the Board of Directors. (b) Within three hundred sixty-five (365) days (such 365 days being the "Application Period") following the consummation of an Asset Sale, the Company or such Restricted Subsidiary shall apply the Net Available Cash from such Asset Sale as follows: (i) first, to the extent the Company or such Restrict ed 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); (ii) second, to the extent of the balance of such Net Available Cash after application in accor dance with clause (i), and to the extent the Company or such Restricted Subsid iary elects (or is required by the terms of any Senior Indebtedness or any Indebt edness of such Restricted Subsidiary), to prepay, repay or purchase Senior Indebtedness (other than Securities) or Indebtedness (other than any Preferred Stock) of a Restricted Subsidiary (in each case other than Indebtedness owed to the Company or an Affiliate of the Company); (iii) third, to the extent of the balance of such Net Available Cash after application in accordance with clauses (i) and (ii), and to the extent the Company or such Restricted Subsidiary elects, to purchase Securities; and (iv) fourth, to the extent of the balance of such Net Available Cash after application in accordance with clauses (i), (ii) and (iii), to make an offer to purchase Securities pursuant to and subject to the conditions of Section 3.12(c); provided, however, that in connection with any prepayment, repayment or purchase of Indebtedness pursuant to clause (ii), (iii) or (iv) above, the Company or such Restricted Subsidiary shall retire such Indebtedness and cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased. To the extent that any Net Available Cash from any Asset Sale remains after the applica tion of such Net Available Cash in accordance with this paragraph, the Company or such Restricted Subsidiary may utilize such remaining Net Available Cash in any manner not otherwise prohibited by the Indenture. To the extent that any or all of the Net Available Cash of any Foreign Asset Sale is prohibited or delayed by applicable local law from being repatriated to the United States, the portion of such Net Available Cash so affect ed shall not be required to be applied at the time provided above, but may be retained by the applicable Restricted Subsidiary so long, but only so long, as the applicable local law will not permit repatriation to the United States (the Compa ny hereby agreeing to promptly take or cause the applicable Restricted Subsidiary to promptly take all actions required by the applicable local law to permit such repatriation). Once such repatriation of any of such affected Net Available Cash is permitted under the applicable local law, such repatriation shall be immediately effected and such repatriated Net Available Cash will be applied in the manner set forth in this Section as if such Asset Sale had occurred on the date of such repatriation. Notwithstanding the foregoing, to the extent that the Board of Directors determines, in good faith, that repatriation of any or all of the Net Available Cash of any Foreign Asset Sale would have a material adverse tax consequence to the Company, the Net Available Cash so affected may be retained outside of the United States by the applicable Restricted Subsidiary for so long as such material adverse tax consequence would continue. Notwithstanding the foregoing, this Section shall not apply to, or prevent any sale of assets, property, or Capital Stock of Subsidiaries to the extent that the fair market value (as determined in good faith by the Board of Directors) of such asset, property or Capital Stock, together with the fair market value of all other assets, property, or Capital Stock of Subsidiaries sold, transferred or otherwise disposed of in Asset Sales during the twelve month period preceding the date of such sale, does not exceed 5% of Consolidated Net Tangible Assets as determined as of the end of the most recent fiscal quarter for which financial statements are available, (it being understood that this provision shall only apply with respect to the fair market value of such asset, property or Capital Stock in excess of 5% of consolidated Net Tangible Assets), and no violation of this provision shall be deemed to have occurred as a consequence thereof. In the event of the transfer of substantially all (but not all) of the property and assets of the Company as an entirety to a Person in a transaction permitted under Article IV, the Successor Corporation shall be deemed to have sold the properties and assets of the Company not so transferred for purposes of this Section 3.12, and shall comply with the provisions of this Section 3.12 with respect to such deemed sale as if it were an Asset Sale. (c) Subject to the last sentence of this paragraph, in the event of an Asset Sale that requires the purchase of Securities pursuant to clause (iii) of the first paragraph of Section 3.12(b), the Company will be required to purchase Securities tendered pursuant to an offer by the Company for the Securities (the "Asset Sale Offer") at a purchase price of not less than their principal amount plus accrued interest to the Asset Sale Purchase Date in accordance with the procedures (including proration in the event of oversubscription) set forth in Section 3.12(d). If the aggregate purchase price of Securities tendered pursuant to the Asset Sale Offer is less than the Net Available Cash allotted to the pur chase of the Securities, the Company shall apply the remaining Net Available Cash in accordance with the last sentence of the first paragraph of Section 3.12(b). The Company shall not be required to make an Asset Sale Offer for Securities pursuant to this Section if the Net Available Cash available therefor (after application of the proceeds as provided in Section 3.12(b)(i) and (ii)) is less than $1,000,000 for any particular Asset Sale (which lesser amounts shall not be carried forward for purposes of determining whether an Asset Sale Offer is required with respect to the Net Available Cash from any subsequent Asset Sale). (d) (1) Promptly, and in any event prior to the 360th day after the later of the date of each Asset Sale as to which the Company must make an Asset Sale Offer or the receipt of Net Available Cash therefrom, the Company shall be obligated to deliver to the Trustee and send, by first-class mail to each Holder, a written notice stating that the Holder may elect to have his Securities purchased by the Company either in whole or in part (subject to proration as hereinafter described in the event the Asset Sale 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 "Asset Sale Purchase Date") and shall contain the information required in a notice for a Change of Control Offer, to the extent applicable. (2) Not later than the date upon which written notice of an Asset Sale Offer is delivered to the Trustee as provided below, the Company shall deliver to the Trustee an Officers' Certificate as to (i) the amount of the Asset Sale Offer (the "Asset Sale Offer Amount"), (ii) the allocation of the Net Avail able Cash from the Asset Sales pursuant to which such Asset Sale Offer is being made and (iii) the compliance of such allocation with the provisions of Section 3.12(a). On such date, the Company shall also deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust) funds in an amount equal to the Asset Sale Offer Amount to be held for payment in accordance with the provisions of this Section. Upon the expiration of the period for which the Asset Sale Offer remains open (the "Offer Period"), the Company shall deliver, or cause to be delivered, to the Trustee the Securities or portions thereof which have been properly tendered to and are to be accepted by the Company. Paying Agent shall promptly, and in any event within one (1) Business Day following the Asset Sale Purchase Date, mail or deliver payment to each tendering Holder in the amount of the purchase price. In the event that the aggregate purchase price of the Securities delivered, or caused to be delivered, by the Company to the Trustee is less than the Asset Sale Offer Amount, the Paying Agent shall deliver the excess to the Company immediately after the expiration of the Offer Period and the delivery to the Trustee of the Securities, or portions thereof that have been properly tendered to and are to be accepted for payment by the Company. (3) Holders electing to have a Security purchased will be required to surrender the Security, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Security duly completed, to the Company or the Paying Agent, as specified in, and at the address specified in, the notice at least ten Business Days prior to the Asset Sale Purchase Date. Holders will be entitled to withdraw their election if the Trustee or the Paying Agent receives, not later than three Business Days prior to the Asset Sale Purchase Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered for purchase by the Holder and a statement that such Holder is withdrawing his election to have such Security purchased. If at the expiration of the Offer Period the aggregate principal amount of Securities surrendered by Holders exceeds the Asset Sale Offer Amount, the Company shall select the Securities to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Company so that only Securi ties in denominations of $1,000, or integral multiples thereof, shall be purchased) and shall notify the Trustee of its selection in a writing signed by two Officers. Holders whose Securities are purchased only in part will be issued new Securities equal in principal amount to the unpurchased portion of the Securities surren dered. (4) At the time the Company delivers Securities to the Trustee which are to be accepted for purchase, the Company will also deliver an Officers' Certificate stating that such Securities are to be accepted by the Company pursu ant to and in accordance with the terms of this Section. A Security shall be deemed to have been accepted for purchase at the time the Paying Agent, directly or through an agent, mails or delivers payment therefor to the surrendering Holder. (e) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section, the Company shall comply with the appli cable securities laws and regulations and shall not be deemed to have breached its obligations under this Section by virtue thereof.

Except as permitted under Article IV, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate existence of each Restricted Subsidiary in accordance with the respective organizational documents of the Company and of each Restricted Subsidiary and the rights (charter and statutory), licenses and franchises of the Company and the Restricted Subsidiaries necessary or appropri ate to carry out their businesses; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate existence of any Restricted Subsidiary, if the preservation thereof is no longer desirable in the conduct of the business of the Company and the Restricted Subsidiaries taken as a whole; and provided, further, that any Restricted Subsid iary may consolidate with, merge into, or sell, convey, transfer, lease or other wise dispose of all or part of its property and assets to the Company or any Wholly Owned Subsidiary to the extent otherwise permitted under this Indenture. SECTION 3.14 Payment of Taxes and Other Claims. The Company shall pay or discharge, or cause to be paid or discharged, before any material penalty accrues thereon all material taxes, assessments and governmental charges levied or imposed upon the Company or any Restricted Subsidiary or upon the income, profits or property of the Compa ny or any Restricted Subsidiary; provided, however, that the Company shall not be required to pay or discharge, or cause to be paid or discharged, any such tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith by appropriate proceedings and for which adequate reserves, if the same shall be required in accordance with GAAP, have been made. SECTION 3.15 Notice of Defaults and Other Events. In the event that any Indebtedness of the Company or any Signifi cant Subsidiary having an outstanding principal amount of $1,000,000 or more individually or $2,500,000 or more in the aggregate has been or could be de clared due and payable before its maturity because of the occurrence of any event of default under such Indebtedness (including any Default under this Indenture), the Company, promptly after it becomes aware thereof, will give written notice thereof to the Trustee.

The Company shall cause all properties used or useful in the conduct of its business or the business of each Restricted Subsidiary and material to the Company and the Restricted Subsidiaries taken as a whole to be maintained and kept in normal condition, repair and working order and supplied with all necessary equipment; provided, however, that nothing in this Section 3.16 shall prevent the Company or any Restricted Subsidiary from discontinuing the use, operation or maintenance of any of such properties or disposing of any of them, if such discontinuance or disposal is, in the judgment of an Officer (or other employee of the Company or any Restricted Subsidiary) of the Company or such Restricted Subsidiary having managerial responsibility for any such property, appropriate. The Company shall provide or cause to be provided, for itself and the Restricted Subsidiaries, insurance (including appropriate self-insurance) against loss or damage of the kinds customarily insured against by corporations similarly situated and owning like properties, including, but not limited to, product liability insurance and public liability insurance with reputable insurers or with the government of the United States of America, or an agency or instrumen tality thereof, of such kinds, and in such amounts, with such deductibles and by such methods as the Company in good faith shall determine to be reasonable and appropriate in the circumstances.

In addition, the Company will, and will cause its Subsidiaries, to conduct their respective businesses in a manner so as to maintain the exemption of the Company and its Subsidiaries from treatment as a public utility holding company under PUHCA or an electric utility or public utility under any federal, state or local law; provided, however, to the extent that any such law is amended following the Issue Date in such a manner that would (absent application of this proviso) make compliance with this Section 3.18 result in a material adverse effect on the Company's results of operations or financial condition, then the Company shall not be required to comply with this Section 3.18, but only to the extent of actions or failures to act that would (absent application of this proviso) constitute violations of this Covenant solely as a result of such amendment. SECTION 3.19 Limitation on Subsidiary Investments.

Any notice of Default given by the Trustee or Securityholders under this Section must specify the Default, demand that it be remedied and state that the notice is a "Notice of Default." The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice of any event which with the giving of notice or the lapse of time or both would become an Event of Default under clause (c), (d), (e) or (g) hereof. Subject to the provisions of Section 6.1 and 6.2, the Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to the Trustee by the Company, the Paying Agent, any Holder or an agent of any Holder. SECTION 5.2 Acceleration. If an Event of Default (other than an Event of Default specified in clause (f) and (g) of Section 5.1 with respect to the Company) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the Securities by notice to the Company and the Trustee, may declare the principal of and accrued and unpaid interest on all the Securities to be due and payable. Upon such declaration the principal and interest shall be due and payable immediately. If an Event of Default specified in clause (f) or (g) of Section 5.1 with respect to the Company occurs, the principal of and interest on all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders. The Holders of a majority in principal amount of the Securities 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 the acceleration. No such rescis sion shall affect any subsequent or other Default or Event of Default or impair any consequent right. SECTION 5.3 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. SECTION 5.4 Waiver of Past Defaults. The Holders of a majority in principal amount of the Securities by notice to the Trustee may waive an existing Default and its consequences except (a) a Default in the payment of the principal of or interest on any Security or (b) a Default in respect of a provision that under Section 8.2 cannot be amended without the consent of each Securityholder affected. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right. SECTION 5.5 Control by Majority. The Holders of a majority in principal amount of the Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, or, subject to Section 6.1, that the Trustee determines is unduly prejudicial to the rights of other Securityholders, or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification reasonably satisfactory to it against all risk, losses and expenses caused by taking or not taking such action. Subject to Section 6.1, the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of the Securityholders pursuant to this Indenture, unless such Securityholders shall have provided to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which might be incurred in compliance with such request or direction. SECTION 5.6 Limitation on Suits. A Securityholder may pursue a remedy with respect to this Inden ture or the Securities only if: (a) the Holder gives to the Trustee written notice of a continuing Event of Default; (b) the Holders of at least 25% in principal amount of the Securities make a written request to the Trustee to pursue the remedy; (c) such Holder or Holders offer to the Trustee security reasonably satisfactory to it or indemnity against any loss, liability or expense; (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or indemnity; and (e) the Holders of a majority in principal amount of the Securities do not give the Trustee a direction inconsistent with the request during such 60-day period. A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder. SECTION 5.7 Rights of Holders To Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal and interest on the Security, on or after the respective due dates expressed in the Security, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder. SECTION 5.8 Collection Suit by Trustee. If an Event of Default specified in Section 5.1(a) or (b) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal and interest remaining unpaid (together with interest on such unpaid interest to the extent lawful) and the amounts provided for in Section 6.7. SECTION 5.9 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents and take such other actions including participating as a member or otherwise in any committees of creditors appointed in the matter as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the amounts provided in Section 6.7) and the Securityholders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, ex penses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 6.7. To the extent that the pay ment of any such amount due to the Trustee under Section 6.7 out of the estate in any such proceeding shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, divi dends, money, securities and other properties which the Holders of the Securities may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. SECTION 5.10 Priorities. If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order: First: to the Trustee for amounts due under Section 6.7; Second: to Securityholders for amounts due and unpaid on the Securities for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and Third: to the Company. The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section. At least 15 days before such record date, the Company shall give written notice to each Securityholder and the Trustee of the record date, the payment date and amount to be paid. SECTION 5.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discre tion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 5.7, or a suit by Holders of more than 10% in principal amount of the Securities. SECTION 5.12 Waiver of Stay or Extension Laws. The Company shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or exten sion law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE VI TRUSTEE SECTION 6.1 Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent Person would exercise or use under the circumstances in the conduct of his own affairs. (b) Except during the continuance of an Event of Default: (i) The Trustee need perform only those duties that are specifically set forth in this Indenture and no others and no implied covenants or obligations shall be read into this Indenture against the Trustee. (ii) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. Howev er, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

(ii) The Trustee shall not be liable for any error of judg ment made in good faith by a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts. (iii) The Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 5.2, 5.4 or 5.5. (iv) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, unless it receives indemnity satisfactory to it against any risk, loss, liability or expense. (d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section. (e) The Trustee, in its capacity as Trustee and Registrar and Paying Agent, shall not be liable to the Company, the Securityholders or any other Person for interest on any money received by it, including, but not limited to, money with respect to principal of or interest on the Securities, except as the Trustee may agree with the Company. (f) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. SECTION 6.2 Rights of Trustee. (a) The Trustee may rely on any document reasonably believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. (b) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate, an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on any such Officers' Certificate or Opinion of Counsel. (c) The Trustee may act through agents and shall not be responsi ble for the misconduct or negligence of any agent appointed with due care. (d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers provided, however, that the Trustee's conduct does not constitute wilful misconduct, negligence or bad faith.

(f) The Trustee shall not be obligated to make any investigation into the facts or matters stated in any resolution, certificate, statement, instru ment, opinion, report, notice, request, direction, consent, order, bond, debenture or any other paper or document. SECTION 6.3 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or an Affiliate with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to Sections 6.10 and 6.11. SECTION 6.4 Trustee's Disclaimer. The Trustee shall not be responsible for and makes no representa tion as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company's use of the proceeds from the Securities, and it shall not be responsible for any statement in the Securities other than its authenti cation. The Trustee shall have no duty to ascertain or inquire as to the perfor mance of the Company's covenants in Article III hereof. SECTION 6.5 Notice of Defaults. If a Default or an Event of Default occurs and is continuing and if it is actually known to a Trust Officer of the Trustee, the Trustee shall mail to Securityholders a notice of the Default or Event of Default within 90 days after a Trust Officer of the Trustee has actual knowledge of the occurrence thereof. Except in the case of a Default in any payment on any Security, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Securityholders. SECTION 6.6 Reports by Trustee to Holders. Within 60 days after the reporting date stated in Section 10.10, the Trustee shall mail to Securityholders a brief report dated as of such date that complies with TIA Sec 313(a) if required by that Section.

A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each stock exchange on which the Securities are listed. The Company shall promptly notify the Trustee when the Securities are listed on any stock exchange and of any delisting thereof. SECTION 6.7 Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation for its services as the parties shall agree. The Trustee's compensa tion shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket disbursements, expenses and advances incurred by it. Such expenses shall include the reasonable compensation and out-of-pocket disburse ments and expenses of the Trustee's agents and counsel. The Company shall indemnify the Trustee for, and hold it harmless against, any loss, liability or expense, including reasonable attorneys' fees, disbursements and expenses, incurred by it arising out of or in connection with the administration of this trust and the performance of its duties hereunder including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder.

To secure the Company's payment obligations in this Section, the Trustee shall have a Lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Securities. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 5.1(f) or (g) occurs, the expenses and the compensation for the services are intended to constitute expenses of adminis tration under any Bankruptcy Law. The Company's obligations under this Section 6.7 and any Lien arising hereunder shall survive the resignation or removal of the Trustee, the discharge of the Company's obligations pursuant to Article VII of this Indenture and the termination of this Indenture. SECTION 6.8 Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Securities may, by written notice to the Trustee, remove the Trustee by so notifying the Trustee and the Company. The Company, by notice to the Trustee, shall remove the Trustee if: (a) the Trustee fails to comply with Section 6.10; (b) the Trustee is adjudged a bankrupt or an insolvent; (c) a receiver or public officer takes charge of the Trustee or its property; or (d) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least 10% in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee fails to comply with Section 6.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resigna tion or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 6.7. SECTION 6.9 Successor Trustee by Merger, etc. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee.

The Trustee shall comply with TIA Sec 310(b). Nothing herein shall prevent the Trustee from filing with the SEC the application referred to in the second-to-last paragraph of TIA Sec 310(b). SECTION 6.11 Preferential Collection of Claims Against Company. The Trustee shall comply with TIA Sec 311(a), except with respect to any creditor relationship listed in TIA Sec 311(b). A Trustee who has resigned or been removed is subject to TIA Sec 311(a) to the extent indicated. ARTICLE VII SATISFACTION AND DISCHARGE OF INDENTURE SECTION 7.1 Discharge of Liability on Securities; Defeasance. If (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.9) for cancellation or (ii) all outstanding Securities have become due and payable and the Company irrevoca bly deposits with the Trustee as trust funds solely for the benefit of the Holders for that purpose funds sufficient to pay at maturity the principal of and all accrued interest on all outstanding Securities (other than Securities replaced pursuant to Section 2.9), and if in either case the Company pays all other sums payable hereunder by the Company, then, subject to Sections 7.2 and 7.7, this Indenture shall cease to be of further effect. The Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Company accompa nied by an Officers' Certificate and an Opinion of Counsel and at the cost and expense of the Company. SECTION 7.2 Termination of Company's Obligations. Except as otherwise provided in this Section 7.2, the Company may terminate its obligations under the Securities and this Indenture if: (i) the Securities mature within one year or all of them are to be called for redemption within one year under arrangements satisfactory to the Trustee for giving the notice of redemption, (ii) the Company irrevocably depos its in trust with the Trustee or Paying Agent (other than the Company or a Subsidiary or Affiliate of the Company) under the terms of an irrevocable trust agreement in form and substance satisfactory to the Trustee, as trust funds solely for the benefit of the Holders for that purpose, money or U.S. Government Obli gations that, through the payment of interest and principal in respect thereof in accordance with its terms, will provide, not later than one (1) Business Day prior to the applicable payment date, money sufficient (in the opinion of a nationally recognized firm of independent public accountants expressed in a written certif ication thereof delivered to the Trustee), without consideration of any reinvest ment of interest, to pay principal and interest on the Securities to maturity or redemption, as the case may be, and to pay all other sums payable by it hereun der, (iii) no Default shall have occurred and be continuing on the date of such deposit, (iv) such deposit will not result in or constitute a Default or result in a breach or violation of, or constitute a default under, any other agreement or in strument to which the Company is a party or by which it is bound and (v) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, in each case stating that all conditions precedent provided for herein relating to the satisfaction and discharge of this Indenture have been complied with; provided that the Trustee or Paying Agent shall have been irrevocably instructed to apply such money or the proceeds of such U.S. Government Obligations to the payment of such principal and interest with respect to the Secu rities. With respect to the foregoing, the Company's obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 2.14, 3.1, 3.2, 6.7, 6.8, 7.5 and 7.6 shall survive until the Securities are no longer outstanding.

provided that the Trustee or Paying Agent shall have been irrevo cably instructed to apply such money or the proceeds of such U.S. Gov ernment Obligations to the payment of such principal and interest with respect to the Securities;

and (v) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, in each case stating that all condi tions precedent provided for herein relating to the defeasance contemplated by this Section 7.3 have been complied with. Notwithstanding the foregoing clause (i), prior to the end of the 123-day period referred to in clause (iv)(B)(2) above, none of the Company's obligations under this Indenture shall be discharged. Subsequent to the end of such 123-day period with respect to this Section 7.3, the Company's obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 2.14, 3.1, 3.2, 6.7, 6.8, 7.6 and 7.7 shall survive until the Securities are no longer outstanding.

After an amendment or supplement under this Section becomes effective, the Company shall mail to Securityholders a notice briefly describing such amendment or supplement. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment or supplement under this Section. SECTION 8.2 With Consent of Holders. The Company and the Trustee may amend or supplement this Indenture or the Securities with the written consent of the Holders of a majority in principal amount of the Securities. However, without the consent of each Securityholder affected, an amendment or supplement under this Section may not: (a) reduce the amount of Securities the Holders of which must consent to an amendment or supplement; (b) reduce the rate of or change the time for payment of interest on any Security; (c) reduce the principal of or change the Stated Maturity of any Security; (d) reduce the premium payable upon the redemption of any Security or change the time at which any Security may or shall be redeemed in accordance with Article IX; (e) make any Security payable in currency or consideration other than that stated in the Security; (f) make any change in Section 5.4, Section 5.7 or this second sentence of this Section 8.2. It shall not be necessary for the consent of the Holders under this Section 8.2 to approve the particular form of any proposed amendment, supple ment or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment or supplement under this Section becomes effective, the Company shall mail to Securityholders a notice briefly describing such amendment or supplement. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment or supplement under this Section. SECTION 8.3 Compliance with Trust Indenture Act.

SECTION 8.4 Revocation and Effect of Consents. Until an amendment or supplement under this Article or a waiver under Article VI becomes effective, a consent to it by a Holder of a Security is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to his Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. After an amendment or supplement becomes effective, it shall bind every Securityholder. SECTION 8.5 Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so deter mines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment. SECTION 8.6 Trustee To Sign Amendments. The Trustee shall sign any supplemental indenture which sets forth an amendment or supplement authorized pursuant to this Article if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such supplemental indenture the Trustee shall be entitled to receive, and (subject to Section 6.1) shall be fully protected in relying upon, an Officers' Certificate and an Opinion of Counsel stating that such supplemental indenture is authorized or permitted by this Indenture and, with respect to an amendment or supplement pursuant to Section 8.2, evidence of the consents of Holders required in connec tion therewith. SECTION 8.7 Fixing of Record Dates. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to take any action under this Indenture by vote or consent. Except as provided herein, such record date shall be the later of 30 days prior to the first solicitation of such consent or vote or the date of the most recent list of Securityholders furnished to the Trustee pursuant to Section 2.5 prior to such solicitation. If a record date is fixed, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to take such action by vote or consent or to revoke any vote or consent previously given, whether or not such Persons continue to be Holders after such record date; provided, however, that unless such vote or consent is obtained from the Holders (or their duly designated proxies) of the requisite principal amount of outstanding Securities prior to the date which is the 120th day after such record date, any such vote or consent previously given shall automatically and without further action by any Holder be canceled and of no further effect.
