The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 in original principal amount and any integral multiple thereof. SECTION 2.03 Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the "Registrar"), an office or agency where Securities may be presented for payment (the "Paying Agent") and an office or agency where notices and demands to or upon the Company in respect of the securities and this Indenture may be served. The Company shall cause the Registrar to keep a register of the Securities and of their transfer and exchange (the "Security Register"). The Company may have one or more co-registrars and one or more additional Paying Agents. The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall give prompt written notice to the Trustee of the name and address of any such Agent and any change in the address of such Agent. If the Company fails to maintain a Registrar, Paying Agent and/or agent for service of notices and demands, the Trustee shall act as such Registrar, Paying Agent and/or agent for service of notices and demands. The Company may remove any Agent upon written notice to such Agent and the Trustee; provided, however, that no such removal shall become effective until (a) the acceptance of an appointment by a successor Agent to such Agent as evidenced by an appropriate agency agreement entered into by the Company and such successor Agent and delivered to the Trustee or (b) notification to the Trustee that the Trustee shall serve as such Agent until the appointment of a successor Agent in accordance with clause (a) of this proviso. The Company, any Subsidiary of the Company, or any Affiliate of any of them may act as Paying Agent, Registrar or coregistrar, and/or agent for service of notice and demands. The Company initially appoints the Trustee as Registrar, Paying Agent and agent for service of notice and demands. If, at any time, the Trustee is not the Registrar, the Registrar shall make available to the Trustee on or before each Interest Payment Date and at such other times as the Trustee may reasonably request the names and addresses of the Holders as they appear in the Security Register. SECTION 2.04 Paying Agent to Hold Money in Trust. No later than each due date of the principal of, premium, if any, and interest on any Securities, the Company shall deposit with the Paying Agent money sufficient to pay such principal, premium, if any, and interest so becoming due. The Company shall require each Paying Agent other 25 than the Trustee to agree in writing that such Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, and interest on the Securities (whether such money has been paid to it by the Company or any other obligor on the Securities), and such Paying Agent shall promptly notify the Trustee of any default by the Company (or any other obligor on the Securities) in making any such payment. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed, and the Trustee may at any time during the continuance of any payment default, upon written request to a Paying Agent, require such Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent shall have no further liability for the money so paid over to the Trustee. If the Company or any Subsidiary of the Company or any Affiliate of any of them acts as Paying Agent, it will, on or before each due date of any principal of, premium, if any, or interest on the Securities, segregate and hold in a separate trust fund for the benefit of the Holders a sum sufficient to pay such principal of, premium, if any, or interest so becoming due until such sums shall be paid to such Holders or otherwise disposed of as provided in this Indenture, and will promptly notify the Trustee of such action or failure to so act. SECTION 2.05 Transfer and Exchange. When Securities are presented to the Registrar or a co-registrar with a request to register the transfer or to exchange them for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar's request. No service charge shall be made for any registration of transfer or exchange of the Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or other similar governmental charge payable upon exchanges pursuant to Section 2.08, 3.08 or 9.04 of this Indenture). The Registrar need not register the transfer or exchange of Securities for a period of fifteen (15) days before a selection of Securities to be redeemed. If a Series A Security is a Restricted Security in certificated form, then as provided in this Indenture and subject to the limitations herein set forth, the Holder, provided it is a Qualified Institutional Buyer, may exchange such Security for a Book-Entry Security by instructing the Trustee (by completing the Transferee Certificate attached to the Security, the form of which is attached to this Indenture as Appendix I) to arrange for such Series A Security to be represented by a beneficial interest in a Global Security in accordance with the customary procedures of the Depository, unless the Company has elected not to issue a Global Security. 26 The Company may at any time determine not to have Securities (other than Restricted Securities) represented in certificated form, in which event the Holder of a Security (other than Restricted Securities) in certificated form may be required to exchange such Security for a Book-Entry Security. Upon any exchange provided for in the preceding paragraph, the Company shall execute and the Trustee shall authenticate and deliver to the Person specified by the Depository a new Security or Securities registered in such names and in such authorized denominations as the Depository, pursuant to the instructions of the beneficial owner of the Securities requesting the exchange, shall instruct the Trustee. Thereupon, the beneficial ownership of such Global Security shown on the records maintained by the Depository or its nominee shall be reduced by the amounts so exchanged and an appropriate endorsement shall be made by or on behalf of the Trustee on the Global Security. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same Indebtedness, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Every Security presented or surrendered for registration of transfer, or for exchange or redemption, shall (if so required by the Company or the Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. Every Restricted Security shall be subject to the restrictions on transfer provided in the legend required to be set forth on the face of each Restricted Security pursuant to Exhibit A, Section 2.12 and the restrictions set forth in this Section 2.05, and the Holder of each Restricted Security, by such Holder's acceptance thereof (or interest therein), agrees to be bound by such restrictions on transfer. The restrictions imposed by this Section 2.05 and Section 2.12 upon the transferability of any particular Restricted Security shall cease and terminate on (a) the later of June 22, 1998 or three years after the last date on which the Company or any Affiliate of the Company was the owner of such Restricted Security (or any predecessor of such Restricted Security) or (b) (if earlier) if and when such Restricted Security has been sold pursuant to an effective registration statement under the Securities Act or transferred pursuant to Rule 144 or Rule 904 under the Securities Act (or any successor provision), unless the Holder thereof is an affiliate of the Company within the meaning of Rule 144 (or such successor provisions). Any Restricted Security as to which such restrictions on transfer shall have expired in accordance with their terms or shall have 27 terminated may, upon surrender of such Restricted Security for exchange to the Registrar in accordance with the provision of this Section 2.05 (accompanied, in the event that such restrictions on transfer have terminated pursuant to Rule 144 or Rule 904 (or any successor provision), by an Opinion of Counsel satisfactory to the Company and the Trustee, to the effect that the transfer of such Restricted Security has been made in compliance with Rule 144 or Rule 904 (or any such successor provision)), be exchanged for a new Series A Security, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by Section 2.12. The Company shall inform the Trustee of the effective date of any Registration Statement registering the Series A Securities under the Securities Act no later than two Business Days after such effective date. Notwithstanding any other provision of this Section 2.05, unless and until it is exchanged in whole or in part for Series A Securities in certificated registered form, a Global Security representing Book-Entry Securities may not be transferred, except as a whole by the Depository to a nominee of the Depository or by another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. Notwithstanding the foregoing, no Global Security shall be registered for transfer or exchange, or authenticated and delivered, whether pursuant to this Section, Section 2.06, 2.08, 3.08, 4.10, 4.11 or 9.04 or otherwise, in the name of a Person other than the Depository for such Global Security or its nominee until (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time the Depository ceases to be a clearing agency registered under the Exchange Act, and a successor Depository is not appointed by the Company within 30 days, (ii) the Company executes and delivers to the Trustee a Company order that all such Global Securities shall be exchangeable or (iii) there shall have occurred and be continuing an Event of Default. Upon the occurrence in respect of any Global Security representing the Securities of any one or more of the conditions specified in clauses (i), (ii), and (iii) of the preceding sentence, such Global Security may be registered for transfer or exchange for Series A Securities in certificated form registered in the names of, authenticated and delivered to, such Persons as the Trustee or the Depository, as the case may be, shall direct. In addition, in accordance with the provisions of this Indenture and subject to certain limitations herein set forth, an owner of a beneficial interest in a Global Security which is a Series A Security may request a Security in certificated form in exchange in whole or in part, as the case may be, for such beneficial owner's interest in the Global Security. Except as provided above, any Security authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, any Global Security, whether 28 pursuant to this Section, Sections 2.06, 2.08, 3.08, 4.10, 4.11 or 9.04 or otherwise, shall also be a Global Security and bear the legend specified in Section 2.13 SECTION 2.06 Replacement Securities. If a mutilated Security is surrendered to the Trustee or if the Holder claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security of like tenor and principal amount. If required by the Trustee or the Company, an indemnity bond must be furnished that is sufficient in the judgment of both the Trustee and the Company to protect the Company, the Trustee or any Agent from any loss that any of them may suffer if a Security is replaced. The Company may charge such Holder for its expenses in replacing a Security. In case any such mutilated, lost, destroyed or wrongfully taken Security has become or is about to become due and payable, the Company in its discretion may pay such Security instead of issuing a new Security in replacement thereof. Every replacement Security is an additional obligation of the Company and shall be entitled to the benefits of this Indenture. SECTION 2.07 Outstanding Securities. Securities outstanding at any time are all Securities that have been authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.07 as not outstanding. A Security does not cease to be outstanding because the Company or one of its Affiliates holds the Security. If a Security is replaced pursuant to Section 2.06, it ceases to be outstanding unless and until the Trustee receives proof satisfactory to it that such replaced Security is held by a bona fide purchaser. If the Paying Agent (other than the Company or an Affiliate of the Company) holds on a maturity date money sufficient to pay Securities payable on that date, then on and after that date such Securities cease to be outstanding and interest on them shall cease to accrue. SECTION 2.08 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 insertions, substitutions, omissions and other variations determined to be appropriate by the Officers executing the temporary Securities, as evidenced by their execution of such temporary Securities. Without unreasonable delay, but in no event later than the date that the Registered Exchange Offer is consummated or a Shelf Registration Statement is declared effective, the Company shall prepare and the Trustee shall authenticate definitive Securities in exchange for temporary Securities. 29 Until so exchanged, the temporary Securities shall be entitled to the same benefits under this Indenture as definitive Securities. SECTION 2.09 Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any securities surrendered to them for transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for transfer, exchange, payment or cancellation and shall destroy them in accordance with its normal procedure. The Company may not issue new Securities to replace Securities it has paid in full or delivered to the Trustee for cancellation. The Series A Securities surrendered to the Trustee for exchange pursuant to the Registered Exchange Offer shall be cancelled and not reissued thereafter. SECTION 2.10 CUSIP Numbers. The Company in issuing the Securities may use "CUSIP" numbers (if then generally in use), and the Company, or the Trustee on behalf of the Company, shall use CUSIP numbers in notices of redemption or exchange as a convenience to Holders; provided, however, that any such notice shall state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice or redemption or exchange and that reliance may be placed only on the other identification numbers printed on the Securities; and provided further, however, that failure to use CUSIP numbers in any notice of redemption or exchange shall not affect the validity or sufficiency of such notice. SECTION 2.11 Defaulted Interest. If the Company defaults in a payment of interest on the Securities, it shall pay, or shall deposit with the Paying Agent money in immediately available funds sufficient to pay, the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest in any lawful manner. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. A special record date, as used in this Section 2.11 with respect to the payment of any defaulted interest, shall mean the fifteenth (15th) day next preceding the date fixed by the Company for the payment of defaulted interest, whether or not such day is a Business Day. At least fifteen (15) days before the subsequent special record date, the Company shall mail to each Holder and to the Trustee a notice that states the subsequent special record date, the payment date and the amount of defaulted interest to be paid. SECTION 2.12 Form of Legend on Restricted Securities. A Series A Security shall be deemed a "Restricted Security" until the later of three years after (a) the Closing Date and (b) the last date on which the Company or any Affiliate of the Company was the owner of a Series A Security (or any predecessor Security) and any Restricted Security, as the case may be, and any Series A Security issued upon registration of transfer of, or in exchange for, or in lieu of, such Restricted Security shall be subject to 30 the restrictions on transfer provided in the legend set forth on the face of the form of Series A Security in Exhibit A; provided, however, that the term "Restricted Security" shall not include (a) any Series A Security which is issued upon transfer of, or in exchange for, any Series A Security which is not a Restricted Security or (b) any Series A Security as to which such restrictions on transfer have been terminated in accordance with Section 2.05. Any Restricted Security shall bear the legend set forth on the face of the Form of Series A Security in Exhibit A hereto. SECTION 2.13 Form of Legend for Book-Entry Securities. Any Global Security authenticated and delivered hereunder shall bear a legend (which would be in addition to any other legends required in the case of a Restricted Security) in substantially the following form: THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITORY OR A NOMINEE OF A DEPOSITORY OR A SUCCESSOR DEPOSITORY. THIS SECURITY IS NOT EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITORY OR ITS NOMINEE EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND NO TRANSFER OF THIS SECURITY (OTHER THAN A TRANSFER OF THIS SECURITY AS A WHOLE BY THE DEPOSITORY TO A NOMINEE OF THE DEPOSITORY OR BY A NOMINEE OF THE DEPOSITORY TO THE DEPOSITORY OR ANOTHER NOMINEE OF THE DEPOSITORY) MAY BE REGISTERED EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT AND ANY SUCH CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 31 ARTICLE 3 Redemption SECTION 3.01 Right of Redemption. The Company may redeem all the Securities at any time or any portion of the Securities from time to time, on or after June 15, 2000, at the following Redemption Prices (expressed as percentages of the principal amount) if redeemed during the 12-month period beginning June 15 of the years indicated: Year Redemption Price ---- ---------------- 2000.................. 105.250% 2001.................. 102.625% 2002 and thereafter... 100.000% of the principal amount, plus accrued and unpaid interest (if any) to the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date). SECTION 3.02 Notices to Trustee. The Company shall notify the Trustee of the listing of the Securities on a national securities exchange within one Business Day after such listing. If the Company elects to redeem Securities pursuant to Section 3.01 of this Indenture and paragraph 6 of the Securities, it shall notify the Trustee in writing of the Redemption Date and the principal amount of Securities to be redeemed. The Company shall give each notice provided for in this Section 3.02 in an Officers' Certificate at least forty-five (45) days before the Redemption Date (unless a shorter period shall be satisfactory to the Trustee). SECTION 3.03 Selection of Securities to Be Redeemed. If less than all the Securities are to be redeemed at any time, the Trustee shall select the Securities to be redeemed in compliance with the requirements of the principal national securities exchange, if any, on which the Securities are listed or, if the Securities are not listed on a national securities exchange, on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem fair and appropriate; provided, however, that no Securities of $1,000 in original principal amount or less shall be redeemed in part. The Trustee shall make the selection from the Securities outstanding and not previously called for redemption. Securities in denominations of $1,000 in original principal amount may only be redeemed in whole. The Trustee may select for redemption portions (equal to $1,000 in original principal amount or any integral multiple 32 thereof) of the principal of Securities that have denominations larger than $1,000 in original principal amount. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company and the Registrar promptly in writing of the Securities or portions of Securities to be called for redemption. SECTION 3.04 Notice of Redemption. At least thirty (30) days but not more than sixty (60) days before a Redemption Date, the Company shall mail a notice of redemption by first class mail to each Holder whose Securities are to be redeemed. The notice shall identify the Securities to be redeemed and shall state: (a) the Redemption Date; (b) the Redemption Price; (c) The name and address of the Paying Agent; (d) that Securities called for redemption must be surrendered to the Paying Agent in order to collect the Redemption Price; (e) that, unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on the Redemption Date and the only remaining right of the Holders is to receive payment of the Redemption Price plus accrued interest to the Redemption Date upon surrender of the Securities to the Paying Agent; (f) that, if any Security is being redeemed in part, the portion of the principal amount (equal to $1,000 in original principal amount or any integral multiple thereof) of such Security to be redeemed and that, on and after the Redemption Date, upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion thereof will be reissued; and (g) that, if any Security contains a CUSIP number as provided in Section 2.10 of this Indenture, no representation is being made as to the correctness of the CUSIP number either as printed on the Securities or as contained in the notice of redemption and that reliance may be placed only on the other identification numbers printed on the Securities. At the Company's request, the Trustee shall give the notice of redemption in the name and at the expense of the Company. Concurrently with the giving of such notice by the Company to the Holders, the Company shall deliver to the Trustee an Officers' Certificate stating that such notice has been given. 33 SECTION 3.05 Effect of Notice of Redemption. Once notice of redemption is mailed, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price. Upon surrender of any Securities to the Paying Agent, such Securities shall be paid at the Redemption Price, plus accrued interest through the Redemption Date. Notice of redemption shall be deemed to be given when mailed, whether or not the Holder receives the notice. In any event, failure to give such notice, or any defect therein, shall not affect the validity of the proceedings for the redemption of the Securities. SECTION 3.06 Deposit of Redemption Price. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent (or, if the Company is acting as its own Paying Agent, shall segregate and hold in trust as provided in Section 2.04 of this Indenture) money sufficient to pay the Redemption Price of and accrued interest on all Securities to be redeemed on that date other than Securities or portions thereof called for redemption on that date that have been delivered by the Company to the Trustee for cancellation. SECTION 3.07 Payment of Securities Called for Redemption. If notice of redemption has been given in the manner provided above, the Securities or portion of Securities specified in such notice to be redeemed shall become due and payable on the Redemption Date at the Redemption Price stated therein, together with accrued interest to such Redemption Date, and from such date (unless the Company shall default in the payment of such Securities at the Redemption Price and accrued interest to the Redemption Date, in which case the principal, until paid, shall bear interest from the Redemption Date at the rate prescribed in the Securities), such Securities shall cease to accrue interest. Upon surrender of any Security for redemption in accordance with a notice of redemption, such Security shall be paid and redeemed by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders registered as such at the close of business on the relevant Record Date. SECTION 3.08 Securities Redeemed in Part. Upon surrender of any Security that is redeemed in part, the Trustee shall authenticate for the Holder a new Security equal in principal amount to the unredeemed portion of such surrendered Security. 34 ARTICLE 4 Covenants SECTION 4.01 Payment of Securities. The Company shall pay the principal of, premium, if any, and interest on the Securities on the dates and in the manner provided in the Securities and this Indenture. An installment of principal, premium, if any, or interest shall be considered paid on the date due if the Trustee or Paying Agent (other than the Company, a Subsidiary of the Company, or any Affiliate of any of them) holds on that date money designated for and sufficient to pay the installment. If the Company, any Subsidiary of the Company, or any Affiliate of any of them acts as Paying Agent, an installment of principal, premium, if any, or interest shall be considered paid on the due date if the entity acting as Paying Agent complies with the last sentence of Section 2.04 of this Indenture. The principal of, premium, if any, and interest on Book-Entry Securities represented by any Global Security shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the sole holder of the Book-Entry Securities represented thereby. The principal of, premium, if any, and interest on the Securities, if they are not Book-Entry Securities represented by a Global Security, shall be payable at the office or agency of the Company maintained for such purpose in The City of New York, or at such other office or agency of the Company as may be maintained for such purpose; provided, however, that at the option of the Company interest may be paid by check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Security Register. The Company shall notify the Trustee within one Business Day after the occurrence of any event resulting in an Interest Rate Increase. The Company shall pay the additional interest arising from an Interest Rate Increase (such interest being called the "Additional Interest") by depositing with the Trustee, in trust, for the benefit of the Holders thereof, on or before the applicable Interest Payment Date, immediately available funds in sums sufficient to pay the Additional Interest then due. The Additional Interest due on any Series A Security shall be payable on each applicable Interest Payment Date to the Person in whose name that Series A Security or the Series B Security for which such Series A Security has been exchanged (or one or more predecessor Securities) is registered at the close of business on the Regular Record Date for the payment of interest due on such Interest Payment Date as set forth in this Indenture. The Company shall notify the Trustee within one Business Day of the occurrence of an event which would result in the termination of the Interest Rate Increase. 35 The Company shall pay interest on overdue principal, premium, if any, and interest on overdue installments of interest, to the extent lawful, at the rate per annum borne by the Securities. SECTION 4.02 Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, the City of New York a Registrar and a Paying Agent and an office or agency 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 shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. SECTION 4.03 Limitation on Indebtedness. (a) The Company will not, and will not permit any Restricted Subsidiary to, Incur any Indebtedness; provided, however, that the Company and its Restricted Subsidiaries may Incur Indebtedness if, after giving effect to the Incurrence of such Indebtedness and the receipt and application of the proceeds therefrom, the Interest Coverage Ratio of the Company would be greater than 2:1x. Notwithstanding the foregoing, the Company and any Restricted Subsidiary may Incur each and all of the following: (i) (A) Indebtedness outstanding at any time under any term loan portion of the Credit Agreements; provided, however, that the aggregate principal amount of such Indebtedness outstanding at any time under this clause (i)(A) shall not exceed $300 million, (B) Indebtedness outstanding at any time under any revolving credit facility under the Credit Agreements or under any other revolving credit or similar arrangements; provided, however, that the aggregate principal amount of such Indebtedness outstanding at any time under this clause (i)(B) shall not exceed the greater of (x) $250 million and (y) the sum of 75% of the Company's and its Restricted Subsidiaries' accounts and notes receivables and 40% of the Company's and its Restricted Subsidiaries' inventory (based on the average accounts and notes receivables (excluding, without duplication, accounts and notes receivables subject to a Receivables Program) and inventory over the last twelve months preceding the date of incurrence), and (C) additional Indebtedness outstanding at any time in an aggregate principal amount not to exceed $50 million; 36 (ii) Indebtedness of the Company to any of its Restricted Subsidiaries, or of a Restricted Subsidiary to the Company or to any other Restricted Subsidiary; (iii) Indebtedness the net proceeds of which are used to refinance outstanding Indebtedness of the Company or any of its Restricted Subsidiaries, other than Indebtedness Incurred under clause (i), (iv) or (v) of this Section 4.03(a) and any refinancings thereof, in an amount (or, if such new Indebtedness provides for an amount less than the principal amount thereof to be due and payable upon a declaration of acceleration thereof, with an original issue price) not to exceed the amount so refinanced (plus premiums, accrued interest, fees and expenses); provided, however, that Indebtedness the proceeds of which are used to refinance the Securities or other Indebtedness of the Company that is subordinated in right of payment to the Securities shall only be permitted under this clause (iii) if (A) in case the Securities are refinanced in part, such Indebtedness, by its terms or by the terms of any agreement or instrument pursuant to which such Indebtedness is issued, is expressly made pari passu with, or subordinate in right of payment to, the Securities, (B) in case the Indebtedness to be refinanced is subordinated in right of payment to the Securities, such Indebtedness, by its terms or by the terms of any agreement or instrument pursuant to which such Indebtedness is issued, is expressly made subordinate in right of payment to the Securities, at least to the extent that the Indebtedness to be refinanced is subordinated to the Securities, and (C) in case the Securities are refinanced in part or the Indebtedness to be refinanced is subordinated in right of payment to the Securities, such Indebtedness, determined as of the date of Incurrence of such new Indebtedness, does not mature prior to six months after the Stated Maturity of the Securities and the Average Life of such Indebtedness is six months greater than the remaining time before the Stated Maturity of the Securities; and provided further, however, that in no event may Indebtedness of the Company that is pari passu with, or subordinated in right of payment to, the Securities be refinanced by means of Indebtedness of any Restricted Subsidiary of the Company pursuant to this clause (iii); (iv) Indebtedness directly or indirectly Incurred to finance capital expenditures of the Company or any of its Restricted Subsidiaries in an aggregate principal amount not to exceed $10 million in any fiscal year of the Company, and any refinancing of any such Indebtedness; provided, however, that the amount of Indebtedness that may be Incurred in any fiscal year of the Company pursuant to this clause (iv) shall be increased by the amount of Indebtedness that could have been Incurred in the prior fiscal year (including 37 by reason of this proviso) of the Company pursuant to this clause (iv) but was not so Incurred; (v) Indebtedness of the Company outstanding at any time in an aggregate amount not to exceed $20 million; provided, however, that such Indebtedness, by its terms or by the terms of any agreement or instrument pursuant to which such Indebtedness is issued, (A) is expressly made subordinate in right of payment to the Securities and (B) provides that no payments of principal of such Indebtedness by way of sinking fund, mandatory redemption or otherwise (including defeasance) may be made by the Company (including, without limitation, at the option of the holder thereof, other than an option given to such holder pursuant to an "asset sale" or "change of control" provision that is no more favorable (except with respect to any premium payable) to the holders of such Indebtedness than the provisions contained in Sections 4.10 and 4.11 of this Indenture and such Indebtedness specifically provides that the Company will not repurchase or redeem such Indebtedness pursuant to such provisions prior to the Company's repurchase of the Securities required to be repurchased by the Company under Sections 4.10 and 4.11 of this Indenture) at any time prior to the Stated Maturity of the Securities; (vi) Indebtedness Incurred by the Company in connection with the purchase, redemption, acquisition, cancellation or other retirement for value of shares of Capital Stock of the Company, options on any such shares or related stock appreciation rights or similar securities, or the satisfaction of put, call, liquidity or other similar rights with respect to any such securities, held by officers, directors or employees or former officers, directors or employees (or their estates or beneficiaries under their estates or their permitted transferees) or by any Plan, upon death, disability, retirement, termination of employment or pursuant to the terms of such Plan or any other agreement under which such shares of stock or related rights were issued or otherwise exist; provided, however, that (A) such Indebtedness, by its terms or by the terms of any agreement or instrument pursuant to which such Indebtedness is issued, is expressly made subordinate in right of payment to the Securities, (B) such Indebtedness, by its terms or by the terms of any agreement or instrument pursuant to which such Indebtedness is issued, provides that no payments of principal of such Indebtedness by way of sinking fund, mandatory redemption or otherwise (including defeasance) may be made by the Company at any time prior to the Stated Maturity of the Securities, and (C) the scheduled maturity of all principal of such Indebtedness is after the Stated Maturity of the Securities;

On the Excess Proceeds Payment Date, the Company will: (a) accept for payment on a pro rata basis Securities or portions thereof tendered pursuant to the Excess Proceeds Offer; (b) deposit with the Paying Agent money sufficient to pay the purchase price of all Securities or portions thereof so accepted; and (c) deliver, or cause to be delivered, to the Trustee all Securities or portions thereof so accepted together with an Officers' Certificate specifying the Securities or portions thereof accepted for payment by the Company.

ARTICLE 6 Default and Remedies SECTION 6.01 Events of Default. An "Event of Default" occurs with respect to the Securities if: (a) the Company defaults in the payment of the principal of, or premium, if any, on, any Security when the same becomes due and payable at maturity, upon acceleration, redemption or otherwise; (b) the Company defaults in the payment of interest on any Security when the same is due and payable, and such default continues for a period of 30 days; (c) the Company defaults in the performance of or breaches any other covenant or agreement of the Company in this Indenture or under the Securities and such default or breach continues for a period of 30 consecutive days after written notice to the Company by the Trustee or the Holders of 25% or more in aggregate principal amount of the Securities; (d) there occurs with respect to any issue or issues of Indebtedness of the Company and/or one or more Significant Subsidiaries having an outstanding principal amount of $10 million or more in the aggregate, whether such Indebtedness now exists or shall hereafter be created, an event of default that has caused the holder or holders thereof, or representatives of such holder or holders, to declare such Indebtedness to be due and payable prior to its Stated Maturity and such Indebtedness has not been discharged in full or such acceleration has not been rescinded or annulled within 30 days of such acceleration; (e) any final judgment or order (not covered by insurance) for the payment of money in excess of $10 million in the aggregate for all such final judgments or orders (treating any deductibles, self-insurance or retention as not so covered) shall be rendered against the Company or any Significant Subsidiary and shall not be discharged, and there shall be any period of 30 consecutive days 58 following entry of the final judgment or order that causes the aggregate amount for all such final judgments or orders outstanding against all such Persons to exceed $10 million during which a stay of enforcement of such final judgment or order, by reason of a pending appeal or otherwise, shall not be in effect; (f) a court having jurisdiction in the premises enters a decree or order for (i) relief in respect of the Company or any Significant Subsidiary in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, (ii) appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official of the Company or any Significant Subsidiary or for all or substantially all the property and assets of the Company or any Significant Subsidiary or (iii) the winding up or liquidation of the affairs of the Company or any Significant Subsidiary and, in each case, such decree or order shall remain unstayed and in effect for a period of 60 consecutive days; (g) the Company or any Significant Subsidiary (i) commences a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consents to the entry of an order for relief in an involuntary case under any such law, (ii) consents to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official of the Company or any Significant Subsidiary or for all or substantially all the property and assets of the Company or any Significant Subsidiary or (iii) effects any general assignment for the benefit of creditors; (h) the Company and/or one or more Significant Subsidiaries fails to make (i) at the final (but not any interim) fixed maturity of any issue of Indebtedness a principal payment of $10 million or more or (ii) at the final (but not any interim) fixed maturity of more than one issue of such Indebtedness principal payments aggregating $10 million or more and, in the case of clause (i), such defaulted payment shall not have been made, waived or extended within 30 days of the payment default and, in the case of clause (ii), all such defaulted payments shall not have been made, waived or extended within 30 days of the payment default that causes the amount described in clause (ii) to exceed $10 million; or (i) the nonpayment of any two or more items of Indebtedness that would constitute at the time of such nonpayments, but for the individual amounts of such Indebtedness, an Event of Default under clause (d) or clause (h) above, or both, and which items of Indebtedness aggregate $10 million or more. The notice required under clause (c) must specify the Default, demand that it be remedied and state that the notice is a "Notice of Default." Such notice shall be 59 given by the Trustee if so requested in writing by the Holders of 25% of the aggregate principal amount of the Securities then outstanding. SECTION 6.02 Acceleration. If an Event of Default (other than an Event of Default specified in clause (f) or (g) of Section 6.01 of this Indenture that occurs with respect to the Company) occurs and is continuing under this Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding, by written notice to the Company (and to the Trustee if such notice is given by the Holders (the "Acceleration Notice")), may, and the Trustee at the request of the Holders will, declare the entire unpaid principal of, premium, if any, and accrued interest on, the Securities to be immediately due and payable, as specified below. Upon a declaration of acceleration, such principal, premium, if any, and accrued interest shall become and be immediately due and payable without presentment, demand, protest or further notice or act (all of which are expressly waived by the Company). In the event of a declaration of acceleration because an Event of Default set forth in clause (d) or (h) of Section 6.01 of this Indenture has occurred and is continuing, such declaration of acceleration shall be automatically rescinded and annulled if the event of default triggering such Event of Default pursuant to clause (d) or (h) shall be remedied, cured by the Company and/or such Significant Subsidiary or waived by the holders of the relevant Indebtedness within 60 days after the declaration of acceleration with respect thereto. If an Event of Default specified in clause (f) or (g) of Section 6.01 of this Indenture occurs with respect to the Company, all unpaid principal of, premium, if any, and accrued interest on, the Securities then outstanding shall become and be immediately due and payable automatically, without any declaration, presentment, demand, protest, notice or other act on the part of the Trustee or any Holder (all of which are expressly waived by the Company). The Holders of at least a majority in principal amount of the outstanding Securities, by written notice to the Company and to the Trustee, may waive all past defaults or Defaults and rescind and annul a declaration of acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and accrued interest on the Securities that have become due solely by such declaration of acceleration, have been cured or waived and (b) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. SECTION 6.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, premium, if any, 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. 60 The Holders and the Trustee may exercise their rights and remedies under this Indenture and under the Securities against the capital stock of TNC or the assets of TNC and its subsidiaries only in a manner consistent with the fiduciary obligations of TNC and the Company associated without the general partnership interests in the Partnerships (including, without limitation, the interests of the Partnerships and the partners thereof); provided that the foregoing shall not require the Holders or the Trustee to take any action with respect to any other assets of the Company. SECTION 6.04 Waiver of Past Defaults. Subject to Sections 6.02, 6.07 and 9.02 of this Indenture, the Holders of at least a majority in aggregate principal amount of the outstanding Securities, by notice to the Trustee, may waive an existing Default or Event of Default and its consequences, except a Default in the payment of principal of, premium, if any, or interest on any Security as specified in clause (a) or (b) of Section 6.01 of this Indenture. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto. SECTION 6.05 Control by Majority. The Holders of at least a majority in aggregate principal amount of the outstanding 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 the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders not joining in the giving of such direction. SECTION 6.06 Limitation on Suits. A Holder may not pursue any remedy with respect to this Indenture or the Securities unless: (a) the Holder gives the Trustee written notice of a continuing Event of Default; (b) the Holders of at least 25% in aggregate principal amount of outstanding Securities make a written request to the Trustee to pursue the remedy; (c) such Holder or Holders offer the Trustee indemnity satisfactory to the Trustee against any costs, liability or expense; (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and 61 (e) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Securities do not give the Trustee a direction that is inconsistent with the request. For purposes of Section 6.05 of this Indenture and this Section 6.06, in determining whether the Holders of the requisite principal amount of outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the Company or 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, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Securities which the Trustee knows to be so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the reasonable satisfaction of the Trustee the pledgee's right so to act with respect to such Securities and that the pledgee is not any obligor upon the Securities or any Affiliate of the Company or such other obligor. A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over any such other Holder. SECTION 6.07 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 the principal of, premium, if any, or interest on, such Holder's Security or to bring suit for the enforcement of any such payment, on or after the respective due dates expressed in the Securities, shall not be impaired or affected without the consent of the Holder. SECTION 6.08 Collection Suit by Trustee. If an Event of Default in payment of principal, premium, if any, or interest specified in clause (a) or (b) of Section 6.01 of this Indenture occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or any other obligor of the Securities for the whole amount of principal, premium, if any, and accrued interest, if any, remaining unpaid, together with interest on overdue principal, premium, if any, and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate borne by the Securities, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the trustee, its agents and counsel. SECTION 6.09 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable 62 compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 of this Indenture) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor of the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any custodian in any judicial proceedings is hereby authorized by each Holder to make such 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 to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due the Trustee under Section 7.06 of this Indenture. To the extent that such payment of reasonable compensation, expenses, disbursements and advances of the Trustee, its agent and counsel out of the estate in any such judicial 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 dividends, distributions, monies, securities and other property that the Holders may be entitled to receive in such judicial proceedings, whether in liquidation or under any plan of reorganization, arrangement or otherwise. Nothing herein contained shall be deemed to empower the Trustee to authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10 Priorities. If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: First: to the Trustee for amounts due under Section 7.06 of this Indenture; Second: to Holders for amounts then due and unpaid for principal of, premium, if any, and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal, premium, if any, and interest, respectively; and Third: to the Company or any other obligors of the Securities, as their interests may appear, or as a court of competent jurisdiction may direct. The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. SECTION 6.11 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 63 party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 of this Indenture, or a suit by Holders of more than 10% in principal amount of the outstanding Securities. SECTION 6.12 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then, and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. SECTION 6.13 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or wrongfully taken Securities in Section 2.06 of this Indenture, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 6.14 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient by the Trustee or by the Holders, as the case may be. ARTICLE 7 Trustee SECTION 7.01 Rights and Duties of Trustee . Subject to TIA Sections 315(a) through (d): (a) If a Default or an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this 64 Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of its own affairs.

Subject to Sections 6.04 and 6.07 of this Indenture and without prior notice to the Holders, the Company, when authorized by the Board of Directors (as evidenced by a Board Resolution), and the Trustee may amend this Indenture and the Securities with the written consent of the Holders of not less than a majority in aggregate principal amount of the Securities then outstanding, and the Holders of not less than a majority in aggregate principal amount of the Securities then outstanding by written notice to the Trustee may waive future compliance by the Company with any provision of this Indenture or the Securities. Notwithstanding the provisions of this Section 9.02, without the consent of each Holder affected, an amendment or waiver, including a waiver pursuant to Section 6.04, may not: (a) change the Stated Maturity of the principal of, or any installment of interest on, any Security, or reduce the principal amount of, or premium, if any, or interest on, any Security, or adversely affect any right of repayment at the option of any Holder of any Security, or change the place or currency of payment of principal of, premium, if any, or interest on, any Security, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity (or in the case of a redemption, on or after the Redemption Date) of any Security; (b) reduce the percentage in principal amount of the outstanding Securities required for any such supplemental indenture, for any waiver of compliance with certain provisions of this Indenture or certain defaults and their consequences provided for in this Indenture; (c) waive a default in the payment of principal of, premium, if any, or interest on, any Security; or (d) modify any of the provisions of this Section 9.02, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding Security affected thereby. It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. The Company will mail supplemental indentures to Holders upon request. Any failure of the Company to mail 76 such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplemental indenture or waiver. SECTION 9.03 Revocation and Effect of Consent. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder 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 security of the consenting Holder; 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 its Security or portion of its Security. Such revocation shall be effective only if the Trustee receives the notice of revocation before the date such amendment, supplement or waiver becomes effective. An amendment, supplement or waiver shall become effective on receipt by the Trustee of written consents from the Holders of the requisite percentage in principal amount of the outstanding Securities. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then, notwithstanding the last two sentences of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies) and only those Persons shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date. After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it is of the type described in any of clauses (a) through (d) of Section 9.02 of this Indenture. In case of an amendment or waiver of the type described in clauses (a) through (d) of Section 9.02 of this Indenture, the amendment or waiver shall bind each Holder who has consented to it and every subsequent Holder of a Security that evidences the same indebtedness as the Security of the consenting Holder. SECTION 9.04 Notation on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the change terms and return it to the Holder and the Trustee may place an appropriate notation on any Security thereafter authenticated. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. SECTION 9.05 Trustee to Sign Amendments, Etc. The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of any amendment, supplement or waiver authorized pursuant to 77 this Article 9 is authorized or permitted by this Indenture. Subject to the preceding sentence, the Trustee shall sign such amendment, supplement or waiver if the same does not adversely affect the rights of the Trustee. The Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver that affects the Trustee's own rights, duties or immunities under this Indenture or otherwise. SECTION 9.06 Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article 9 shall conform to the requirements of the TIA as then in effect.

Copies of any such 78 communication or notice to a Holder shall also be mailed to the Trustee and each Agent at the same time. 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.
