The Company and the Trustee may charge for their expenses in replacing a Security. If, after the delivery of such replacement Security, a bona fide purchaser of the original Security in lieu of which such replacement Security was issued presents for payment or registration such original Security, the Trustee shall be entitled to recover such replacement
Security from the Person to whom it was delivered or any Person taking therefrom, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Trustee or the Company in connection therewith.

relying upon any such quorum, consent or vote, only Securities which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded.

         If a Security is replaced pursuant to Section 2.08 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser.

         If the principal amount of any Security is considered paid under Section 3.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

         Except as set forth in Section 2.10 hereof, a Security does not cease to be outstanding because the Company or any of its Affiliates holds the Security.

Section 2.13. Defaulted Interest.

         If the Company defaults in a payment of interest on the Securities, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest on the defaulted interest, in each case at the rate provided in the Securities and in Section 3.01 hereof.

ARTICLE V

DEFAULTS AND REMEDIES

Section 5.01. Events of Default.

         An "Event of Default," occurs if:

                  (i) the Company defaults in the payment of any interest or Liquidated Damages, if any, on any Security when the same becomes due and payable and the default continues for a period of 30 days;

                  (ii) the Company defaults in the payment of the principal of or premium, if any, on any Security at its Maturity, upon redemption or by declaration;

                  (iii) the Company fails to observe or perform any of its covenants or agreements listed in Sections 3.05, 3.07, 3.08, 3.09 or 3.10 hereof and such Default continues for a period of 30 days after the notice specified below;

                  (iv) the Company fails to comply with any of its other covenants or agreements contained in the Securities or this Indenture and such Default continues for a period of 90 days after the notice specified below;

                  (v) the Company or any Restricted Subsidiary defaults (A) in the payment of any installment of principal of or interest upon any  Funded Debt having a then outstanding principal amount in excess of $25 million, the effect of which default is to cause or permit the trustee  or holders of such Funded Debt to cause such Funded Debt to become due and payable prior to its Stated Maturity; or (B) in any other manner as defined in any instrument evidencing Funded Debt having a then outstanding principal amount in excess of $25 million, which default has resulted in the acceleration of such Funded Debt so that the same shall have become due and payable prior to its Stated Maturity, provided, however, that if any default as provided in clause (A) or (B) above shall be remedied or cured by the Company or a Restricted
Subsidiary or waived by the trustee or holders of such Funded Debt, in each case in accordance with the terms of the instruments pursuant to which such Funded Debt shall have been issued, then the default hereunder by reason thereof shall be deemed likewise to have been thereupon remedied, cured, or waived without further action upon the part of either the Trustee or any of the Holders; and provided,  further, that subject to the provisions of this Indenture, the Trustee shall not be charged with knowledge of any such default unless either  (x) a Responsible Officer of the Trustee assigned to its corporate trust department shall, as such officer, have actual knowledge of such default, or (y) written notice thereof shall have been given to the Trustee by the Company, by the trustee or holders of any such Funded Debt, or by the Holders of not less than 25% in aggregate principal amount of the Securities at the time outstanding;



 -39-







                  (vi) a decree or order by a court having jurisdiction in the premises shall have been entered adjudging the Company or any Restricted Subsidiary of the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment, composition, liquidation, dissolution or winding-up of the Company or any Restricted Subsidiary of the Company or any similar relief under any present or future federal or state law or regulation, and such decree or order shall have continued undischarged or unstayed for a period of 90 consecutive days; or a decree or order of a court having jurisdiction in the premises for the appointment of a receiver or trustee or assignee in bankruptcy or insolvency of the Company or any Restricted Subsidiary of the Company or of its property, or for the winding-up or liquidation of its affairs, shall have been entered, and such decree or order shall have remained in force undischarged and unstayed for a period of 90 consecutive days; or

                  (vii) the Company or any Restricted Subsidiary shall institute proceedings to be adjudicated a voluntary bankrupt, or shall consent to  the institution of a bankruptcy proceeding against it, or shall file a petition or answer or consent seeking reorganization, arrangement, adjustment, composition, liquidation, dissolution, winding-up or any similar relief under any present or future federal or state law or consent to the appointment of a receiver or trustee or assignee in bankruptcy or insolvency of it or of its property, or shall make an assignment for the benefit of creditors, or shall admit in writing its inability to pay its debts generally as they become due.

         A Default under clause (iii) or (iv) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company and the Trustee, of the Default and the Company does not cure the Default within the time period specified above. The notice must specify the Default, demand that it be remedied and state that the notice is a "Notice of Default." When a Default is cured, it ceases. Such notice shall be given by the Trustee if so requested by the Holders of at least 25% in principal amount of the Securities then outstanding.

         Subject to the provisions of Section 6.01 and Section 6.02, the Trustee shall not be charged with knowledge of an Event of Default unless written notice thereof shall have been given to a Responsible Officer at the Corporate Trust Office of the Trustee by the Company, the Paying Agent, any Holder or an agent of any Holder.

Section 5.02. Acceleration.

         If an Event of Default (other than an Event of Default specified in clause (vi) or (vii) of Section 5.01 hereof with respect to the Company) occurs and is continuing, the Trustee may by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities may, by
notice to the Company and the Trustee, and the Trustee shall, upon the request of such Holders, declare


-40-

 
 

 



the principal of, premium, if any, on, accrued and unpaid interest on, and Liquidated Damages, if any, on all then outstanding Securities (if not then due and payable) to be due and payable, and upon any such declaration the same shall become and be immediately due and payable. If an Event of Default specified in clause (vi) or (vii ) of Section 5.01 hereof with respect to the Company occurs, the principal of, premium, if any, on, accrued and unpaid interest on, and Liquidated Damages, if any, on all Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holder.

         At any time after such a declaration of acceleration with respect to the Securities has been made and before a judgment for payment of the money due has been obtained by the Trustee as hereinafter in this Article V, the Holders of a majority in principal amount of the outstanding Securities, by written
notice to the Company and the Trustee, may rescind and annul such acceleration and its consequences if:
                   (i) all existing Events of Default, other than the non-payment of the principal of the Securities which has become due solely by such declaration of acceleration, have been cured or waived;

                  (ii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of  acceleration, has been paid; and

                  (iii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

Section 5.03. Other Remedies.

         If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, or premium, if any, Liquidated Damages, if any, or interest on the Securities or to enforce the performance of any provision of the Securities, this Indenture or any Registration Rights Agreement.

         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 Holder 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 5.04. Waiver of Existing Defaults.

         Subject to Section 5.07 and Section 8.02, the Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences (including waivers obtained in connection with a tender offer or exchange offer for the
Securities or a solicitation of consents in respect of the Securities, provided that in each case such offer or solicitation is made to all Holders of the Securities then outstanding on equal terms), except (1) a continuing Default or Event of Default in the payment of the principal of, or premium, if any, or



-41-

 
 

 



Liquidated Damages, if any, or interest on the Securities or (2) a continuing Default in respect of a provision that under Section 8.02 hereof cannot be amended without the consent of each Holder affected. 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 impair any right consequent thereon.

Section 5.05. Control by Majority.

         The Holders of a majority in principal amount of the Securities then outstanding 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 hereunder. However, the Trustee may refuse to follow any direction that conflicts with applicable law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of other Holders, or that may 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 satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

Section 5.06. Limitations on Suits.

         Subject to Section 5.07 hereof, a Holder may pursue a remedy with respect to this Indenture or the Securities only if:

                  (i) such Holder gives to the Trustee written notice of a continuing Event of Default;

                  (ii) the Holders of at least 25% in principal amount of the Securities then outstanding make a written request to the Trustee to pursue the remedy;

                  (iii) such Holder or Holders offer to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense;

                  (iv) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

                  (v) during such 60-day period the Holders of a majority in principal amount of the Securities do not give the Trustee a direction inconsistent with the request.

         A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder.


 -42-

 
 

 



Section 5.07. 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 principal of, and premium, if any, 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, is absolute and unconditional and shall not be impaired or affected without the consent of such Holder.

Section 5.08. Collection Suit by Trustee.

         If an Event of Default specified in clause (i) or (ii) of Section 5.01 hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the amount of principal and premium, if any, and interest (and Liquidated Damages, if any) remaining unpaid on the Securities, and interest on overdue principal, premium, if any, and Liquidated Damages, if any and, to the extent lawful, interest on overdue interest (and Liquidated Damages, if any), 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 5.09. Trustee May File Proofs of Claim.

         The Trustee is authorized to file such proofs of claim and other papers or documents and to take such actions, including participating as a member, voting or otherwise, of any committee of creditors, as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company or its creditors or properties and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any Custodian in any such judicial proceeding 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 agents and counsel, and any other amounts due the Trustee under Section 6.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07 hereof 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, dividends, money, securities and other properties which the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize 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.

         If a Default or Event of Default occurs and is continuing and it is actually known to a Responsible Officer of the Trustee, the Trustee shall mail to Holders a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, Liquidated Damages, if any, or interest on any Security, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Holders.

Section 6.06. Reports by Trustee to Holders.

         On or before July 15 of each year, beginning with July 15, 2003, the Trustee shall mail to Holders a brief report dated as of a date convenient to the Trustee no more than 60 nor less than 45 days prior thereto, that complies with TIA Section 313(a); provided, however, that if no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted.

The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense.

Section 6.08. 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 6.08.

Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Securities then outstanding may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

         If a successor Trustee does not take office within 30 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 then outstanding may petition (at the expense of the Company) any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee.

         If the Trustee fails to comply with Section 6.10 hereof, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Thereupon the resignation 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 Holders. 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 6.07 hereof.

Section 8.02. With Consent of Holders.

         Except as provided below in this Section 8.02, the Company and the Trustee may amend or supplement this Indenture or the Securities with the written consent (including consents obtained in connection with a tender offer or exchange offer for the Securities or a solicitation of consents in respect of the Securities; provided that in each case such offer or solicitation is made to all Holders of the Securities then outstanding on equal terms) of the Holders of at least a majority in principal amount of the Securities then outstanding.

         Upon the request of the Company accompanied by a resolution of the Board of Directors of the Company authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 8.06 hereof, the Trustee shall join with the Company in the execution of such supplemental indenture.

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

         The Holders of a majority in principal amount of the Securities then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Securities (including waivers obtained in connection with a tender offer or exchange offer for the Securities or a solicitation of consents in respect of the Securities, provided that in each case such offer or solicitation is made to all Holders of the Securities then outstanding on equal terms).

Section 8.03. Compliance with Trust Indenture Act.

         Every amendment to this Indenture or the Securities shall comply in form and substance with the TIA as then in effect.

Section 8.04. Revocation and Effect of Consents.

         A consent to an amendment (which includes a supplement) or waiver 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 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 or her Security or portion of a Security if the Trustee receives written notice of revocation at any time prior to (but not after) the date the Trustee receives an Officers' Certificate certifying that the Holders of the requisite principal amount of Securities have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.


-57-

 
 

 



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 or waiver or to take any other action under this Indenture. If a record date is fixed, then notwithstanding the provisions 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 consent shall be valid or effective for more than 90 days after such record date unless consents from Holders of the principal amount of the Securities required hereunder for such amendment or waiver to be effective shall have also been given and not revoked within such 90-day period.

         After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it is of the type described in any of clauses (i) through (vii) of Section 8.02 hereof. In such case, the amendment or waiver shall bind each Holder who has consented to it and every subsequent Holder that evidences the same debt as the consenting Holder's Security.

Section 8.05. 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 determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

Date (unless the Trustee consents in writing to a shorter period of at least 30 days prior to the Redemption Date), an Officers' Certificate setting forth the Redemption Date, the principal amount of such Securities to be redeemed and the Redemption Price.

Section 9.02. Selection of Securities to be Redeemed.

         If less than all of the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed on a pro rata basis, by lot or by any other method that the Trustee in its sole discretion shall deem fair and appropriate. The particular Securities to be redeemed shall be selected, unless otherwise provided herein, not less than 30 days nor more than 60 days prior to the Redemption Date by the Trustee from the outstanding Securities not previously called for redemption.

         The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Security selected for partial redemption, the principal amount thereof to be redeemed. Securities and portions of them selected shall be in amounts of $1,000 or whole multiples of
$1,000. Except as provided in the preceding sentence, provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption.

Section 9.03. Notices to Holders.

         (a) At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail in conformity with Section 10.02 a notice of redemption to each Holder whose Securities are to be redeemed.

         The Notice shall identify the Securities to be redeemed (including
CUSIP numbers, if any) and shall state:

                  (A)      the Redemption Date;

                  (B)      the Redemption Price;

                  (C) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the Redemption Date, upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion will be issued;

                  (D)      the name and address of the Paying Agent;

                  (E) that Securities called for redemption must be surrendered to the Paying Agent at the address specified in such notice to collect the Redemption Price;

                  (F) that unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on and after the Redemption Date and the only remaining right of the  Holders is to receive payment of the Redemption Price upon surrender to the Paying Agent of the Securities; and



 -59-

 
 

 




                  (G) the aggregate principal amount of Securities being redeemed.

         If any of the Securities to be redeemed is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to redemptions.

         (b) At the Company's request, the Trustee shall give the notice required in Section 9.03(a) in the Company's name; provided, however, that the Company shall deliver to the Trustee, at least 45 days prior to the Redemption Date (unless the Trustee consents in writing to a shorter period at least 30 days prior to the Redemption Date), an Officers' Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 9.03(a).

Section 9.04. Effect of Notices of Redemption.

         Once notice of redemption is mailed pursuant to Section 9.03, Securities called for redemption become due and payable on the Redemption Date at the Redemption Price. Upon surrender to the Paying Agent, such Securities shall be paid out at the Redemption Price.

Section 9.05. Deposit of Redemption Price.

         At or prior to 11:00 am New York City time on the Redemption Date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the Redemption Price of all Securities to be redeemed on that date. The Trustee or the Paying Agent shall return to the Company any money not required for that purpose less the expenses of the Trustee as provided herein.

         If the Company complies with the preceding paragraph, interest on the Securities or portions thereof to be redeemed (whether or not such Securities are presented for payment) will cease to accrue on the applicable Redemption Date. If any Security called for redemption shall not be so paid upon surrender because of the failure of the Company to comply with the preceding paragraph, then interest will be paid on the unpaid principal and premium, if any, from the Redemption Date until such principal and premium are paid and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the
rate provided in the Securities and in Section 3.01.

Section 9.06. Securities Redeemed in Part.

         Upon surrender of a Security that is redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder, at the expense of the Company, a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

[REVERSE OF SECURITY]

                          SOUTHERN NATURAL GAS COMPANY

                        8 7/8% Series [A/B] Note due 2010

         This Security is one of a duly authorized issue of 8 7/8% Series [A/B] Notes due March 15, 2010 (the "Securities") of Southern Natural Gas Company, a Delaware corporation (the "Company").

         1. Interest. The Company promises to pay interest on the principal amount of this Security at 8 7/8% per annum from [   ], [   ] until maturity. The Company will pay interest semiannually on March 15 and September 15 of each year (each an "Interest Payment Date"), or if any such day is not a Business Day, on the next succeeding Business Day. Interest on the Securities will accrue from the most recent Interest Payment Date on which interest has been paid or, if no interest has been paid, from [   ], [   ]; provided that if there is no existing Default in the payment of interest, and if this Security is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be [ ], [   ] and interest accrued from [   ], [   ] shall be payable on such date. Further, the Company shall pay interest on overdue principal and premium, if any, from time to time on demand at a rate equal to the interest rate then in effect; it shall pay interest on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

         2. Method of Payment. The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the record date next preceding the Interest Payment Date, even if such Securities are canceled after such record date and on or before such Interest Payment Date. The Holder must surrender this Security to a Paying Agent to collect payments of principal and premium, if any. The Company will pay the principal of, and premium, if any, and interest on the Securities in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium, if any, Liquidated Damages, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium, if any, Liquidated Damages, if any, and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).



A-5

 
 

 



3. Ranking. The Securities are senior unsecured obligations of the Company.

         4. Optional Redemption. The Securities may be redeemed, in whole or part, at the Company's option at any time in whole, or from time to time in part, prior to March 15, 2007, at the Make-Whole Price (as defined below) in accordance with the provisions of the Indenture.

         "Make-Whole Price" means an amount equal to the greater of

         (i) 100% of the principal amount of the Securities then outstanding to be redeemed, and

         (ii) as determined by an Independent Investment Banker, the sum of the present values of (A) the redemption price of the Securities at March 15, 2007 (as set forth below) and (B) the remaining scheduled payments of interest from the Redemption Date to March 15, 2007 (not including any portion of such payments of interest accrued as of the Redemption Date) discounted back to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 75 basis points,

plus, in the case of both (i) and (ii), accrued and unpaid interest and Liquidated Damages, if any, to the Redemption Date. Unless the Company defaults in the payment of the Make-Whole Price, on and after the applicable Redemption Date, interest shall cease to accrue on the Securities to be redeemed.

         "Comparable Treasury Issue" means the U.S. Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities.

         "Comparable Treasury Price" means, with respect to any Redemption Date, (i) the average of four Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

         "Independent Investment Banker" means Salomon Smith Barney Inc. or Credit Suisse First Boston LLC and their respective successors at the Company's option, or, if such firms or the successors, if any, to such firms, as the case may be, are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.

         "Reference Treasury Dealer" means Salomon Smith Barney Inc. or Credit Suisse First Boston LLC, at the Company's option, and three additional primary U.S. government securities dealers in New York City (each a "Primary Treasury Dealer") selected by the Company, and their respective successors; provided, however, that if any such firm or any such successor, as the case may be, shall cease to be a primary U.S. government securities dealer in New York City, the Company shall substitute therefore another Primary Treasury Dealer.


A-6

 
 

 




         "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

         "Treasury Rate" means, with respect to any Redemption Date, (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated "H.15(519)" or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption "Treasury Constant Maturities," for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Stated Maturity, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined, and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

         The notice of redemption with respect to the foregoing redemption need not set forth the Make-Whole Price but only the manner of calculation thereof. The Company shall notify the Trustee of the Make-Whole Price with respect to any redemption promptly after the calculation thereof, and the Trustee shall not be responsible for such calculation.

         Beginning on March 15, 2007, the Company may redeem the Securities, in whole or in part, at the Company's option at any time or from time to time, at the following redemption prices (expressed as percentages of principal amount), plus accrued and unpaid interest and Liquidated Damages, if any, to the applicable Redemption Date, if redeemed during the 12-month period beginning on each March 15 of the years indicated below:


             Year                                          Percentage
             ----                                                - ----------

            2007                                             104.438%
            2008                                             102.219%
            2009 and thereafter                        100.000%

5. Paying Agent and Registrar. Initially, The Bank of New York (the "Trustee"), the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar, co-registrar or additional paying agent without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

         6. Indenture. The Company issued the Securities under an Indenture dated as of March 5, 2003 (as amended, supplemented or otherwise modified form time to time, the "Indenture") between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb), as in effect on the date of execution of the Indenture (the "TIA"). The Securities are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Securities are unsecured general obligations of the Company. Capitalized terms used but not defined in this Security have the respective meanings given to such terms in the Indenture. The Company may issue Additional Securities under the Indenture subject to compliance with Section 3.08 thereof, unlimited in aggregate principal amount.

         7. Denominations, Transfer, Exchange. The Securities are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not exchange or register the transfer of any Securities during the period between a record date and the corresponding Interest Payment Date.

         8. Persons Deemed Owners. The registered Holder of a Security shall be treated as its owner for all purposes.

         9. Amendments and Waivers. Subject to certain exceptions and limitations, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Securities, and compliance in a particular instance by the Company with any provision of the Indenture may be waived (other than certain provisions, including any continuing Default or Event of Default in the payment of the principal of, or premium, if any, or interest on the Securities) by the Holders of at least a majority in principal amount of the Securities then outstanding in accordance with the terms of the Indenture. Without the consent of any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency; to comply with the Indenture in the case of the merger, consolidation or sale or other disposition of all or substantially all of the assets of the Company; to provide for uncertificated Securities in addition to or in place of certificated Securities; to add any additional Events of Default; to provide for the acceptance under the Indenture of a successor trustee in compliance with the provisions thereof; to secure the Securities pursuant to the requirements under the Indenture; to comply with any requirements in order to effect or maintain the qualification of the Indenture under the TIA to comply with

A-8

 
 

 



any requirements of the SEC in connection with qualifying the Indenture under the TIA; to add to the covenants of the Company for the benefit of the Holders or to surrender any power conferred upon the Company; or to make any change that does not adversely affect the rights of any Holder in any material respect.

         The right of any Holder to participate in any consent required or sought pursuant to any provision of the Indenture (and the obligation of the Company to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which such consent is required or sought as of a date identified by the Trustee in a notice furnished to Holders in accordance with the terms of the Indenture.

         Without the consent of each Holder affected, the Company may not (i) reduce the percentage of principal amount of Securities whose Holders must consent to an amendment, supplement or waiver, (ii) reduce the rate of or change the time for payment of interest, including default interest, on any Security, (iii) reduce the principal of or change the fixed maturity of any Security or alter the premium or other provisions with respect to redemption, (iv) change the place of payment or make any Security payable in money other than that stated in the Security, (v) impair the right to institute suit for the enforcement of any payment of principal of, or premium, if any, or interest on any Security, (vi) make any change in the percentage of principal amount of Securities necessary to waive compliance with certain provisions of the
Indenture or (vii) waive a continuing Default or Event of Default in the payment of principal of, or premium, if any, or interest on the Securities.

         10. Defaults and Remedies. Generally, an Event of Default occurs if: (i) the Company defaults in the payment of any interest or Liquidated Damages, if any, on any Security when the same becomes due and payable and the default continues for a period of 30 days; (ii) the Company defaults in the payment of the principal of or premium, if any, on any Security at its Maturity or otherwise; (iii) the Company fails to observe or perform any of its covenants or agreements listed in Sections 3.05, 3.07, 3.08, 3.09 or 3.10 of the Indenture and such Default continues for a period of 30 days after the notice specified below; (iv) the Company fails to comply with any of its other covenants or agreements contained in the Securities or the Indenture and such Default continues for a period of 90 days after the notice specified below; (v) the Company or any Restricted Subsidiary defaults (A) in the payment of any installment of principal of or interest upon any Funded Debt having a then outstanding principal amount in excess of $25 million, the effect of which default is to cause or permit the trustee or holders of such Funded Debt to cause such Funded Debt to become due and payable prior to its Stated Maturity; or (B) in any other manner as defined in any instrument evidencing Funded Debt having a then outstanding principal amount in excess of $25 million, which default has resulted in the acceleration of such Funded Debt so that the same shall have become due and payable prior to its Stated Maturity, provided, however, that if any default as provided in clause (A) or (B) above shall be remedied or cured by the Company or a Restricted subsidiary or waived by the trustee or holders of such Funded Debt, in each case in accordance with the terms of

A-9

 
 

 



the instruments pursuant to which such Funded Debt shall have been issued, then the Default hereunder by reason thereof shall be deemed likewise to have been thereupon remedied, cured, or waived without further action upon the part of either the Trustee or any of the Holders; and provided, further that subject to the provisions of the Indenture, the Trustee shall not be charged with knowledge of any such default unless either (x) a Responsible Officer of the Trustee assigned to its corporate trust department shall, as such officer, have actual knowledge of such default, or (y) written notice thereof shall have been given to the Trustee by the Company, by the trustee or holders of any such Funded Debt, or by the Holders of not less than 25% in aggregate principal amount of the Securities at the time outstanding; or (vi) certain events of bankruptcy or liquidation with respect to the Company occur. A Default under clause (iii) or (iv) is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company and the Trustee of the Default and the Company does not cure the Default within the time period specified above. The notice must specify the Default, demand that it be remedied and state that the notice is a "Notice of Default." When a Default is cured, it ceases. Such notice shall be given by the Trustee if so requested by the Holders of at least 25% in principal amount of the Securities then outstanding.

         If an Event of Default (other than an Event of Default specified in clause (vi) above) occurs and is continuing, the Trustee may, by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities may declare by notice to the Company and the Trustee, and the Trustee shall, upon the request of such Holders the principal of, premium, if any, and accrued and unpaid interest and Liquidated Damages, if any, on all then outstanding Securities (if not then due and payable) to be immediately due and payable, and upon any such declaration the same shall become and be immediately due and payable. The amount due and payable upon the acceleration of any Security is equal to 100% of the principal amount thereof plus premium, if any, and accrued and unpaid interest and Liquidated Damages, if any, to the date of payment. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. If an Event of Default specified in clause (vi) above with respect to the Company occurs, the principal of, premium, if any, on, accrued and unpaid interest on, and Liquidated Damages, if any, on all Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holder.

         11. Discharge Prior to Maturity. The Indenture shall be discharged and canceled upon the payment of all of the Securities and shall be discharged except for certain obligations upon the irrevocable deposit with the Trustee of funds or U.S. Government Obligations sufficient for such payment.

         12. Trustee Dealings with the Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee.

         13. No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Company or of any Affiliate shall not have any liability for any obliga- tions of the Company under the Securities or the Indenture or for any claim

A-10

 
 

 



based on, in respect of or by reason of such obligations or their creation by reason of his, her or its status as such. Each Holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

         14. Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

         15. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other
identification numbers printed thereon.

         16. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

         17. Governing Law. THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUCTED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, THE COMPANY HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF ANY NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN IN THE CITY OF NEW YORK OR ANY FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN IN THE CITY OF NEW YORK IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE SECURITIES AND IRREVOCABLY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, JURISDICTION OF THE AFORESAID COURTS.

In addition to the rights provided to Holders of Securities under the Indenture, Holders of Transfer Restricted Securities shall have all the rights set forth in the Registration Rights Agreement applicable to such Securities. Each Holder of a Transfer Restricted Security , by his acceptance thereof, acknowledges and agrees to the provisions of such Registration Rights Agreement, including without limitation the obligations of the Holders with respect to a registration and the indemnification of the Company to the extent provided therein.].**
