ARTICLE II GENERAL TERMS AND CONDITIONS OF THE SUBORDINATED DEBENTURES Section 2.1. Designation and Principal Amount. There is hereby authorized a series of Debt Securities designated the "8.04% Junior Subordinated Deferrable Interest Debentures due March 31, 2038," limited in aggregate principal amount to $154,640,000, which amount shall be as set forth in any written order of the Company for the authentication and delivery of such Debt Securities pursuant to Section 2.04 of the Indenture. Section 2.2. Maturity. The Maturity Date will be the Stated Maturity Date provided that the Company may at its option at any time prior to the Stated Maturity Date extend the Maturity Date to a date not later than March 31, 2047; provided, however, that at the time such election is made and at the effective time of such extension (as specified by the Company) (i) the Company is not in bankruptcy, otherwise insolvent or in liquidation, (ii) the Company is not in default in the payment of any interest or principal on the Subordinated Debentures, and (iii) in the case of Subordinated Debentures held by the Trust, the Trust is not in arrears on payments of Distributions and no deferred Distributions are accumulated. In the event the Company elects to extend the stated maturity of the Subordinated Debentures, it shall give notice of any such change to the Trustee, and the Trustee shall give notice of such extension to the Holders of the Subordinated Debentures, not more than 90 and not less than 30 days prior to the effective time of such extension. Section 2.3. Form and Payment. Except as provided in Section 2.4, the Subordinated Debentures shall be issued in fully registered certificated form without interest coupons. Principal and interest on the Subordinated Debentures issued in certificated form will be payable, the transfer of such Subordinated Debentures will be registrable and such Subordinated Debentures will be exchangeable for Subordinated Debentures bearing identical terms and provisions at the office or agency of the Trustee in Chicago, Illinois, provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered holder at such address as shall appear in the Security Register or by wire transfer to such account as may have been appropriately -3- designated by such holder. Notwithstanding the foregoing, so long as the registered holder of any Subordinated Debentures is the Property Trustee, the payment of the principal of and interest (including Compounded Interest and Additional Interest, if any) on such Subordinated Debentures held by the Property Trustee will be made at such place and to such account as may be designated by the Property Trustee. The Subordinated Debentures will be denominated in U.S. dollars and payments of principal and interest on the Subordinated Debentures shall be made in U.S. dollars. Section 2.4. Global Subordinated Debenture. In connection with the dissolution of the Trust: (a) the Subordinated Debentures in certificated form may be presented to the Trustee by the Property Trustee in exchange for a Global Security in an aggregate principal amount equal to the aggregate principal amount of the Subordinated Debentures so presented, to be registered in the name of the Depositary, or its nominee, and delivered by the Trustee to the Depositary for crediting to the accounts of its participants pursuant to the instructions of the Regular Trustees. The Company, upon any such presentation, shall execute a Global Security in such aggregate principal amount and deliver the same to the Trustee for authentication and delivery in accordance with the Indenture and this Second Supplemental Indenture. Payments on the Subordinated Debentures issued as a Global Security will be made to the Depositary; and (b) if any Preferred Securities are held in non book-entry certificated form, the Subordinated Debentures in certificated form may be presented to the Trustee by the Property Trustee and any Preferred Security Certificate which represents Preferred Securities other than Preferred Securities held by the Clearing Agency or its nominee ("Non Book-Entry Preferred Securities") will be deemed to represent beneficial interests in Subordinated Debentures presented to the Trustee by the Property Trustee having an aggregate principal amount equal to the aggregate stated liquidation amount of the Non Book-Entry Preferred Securities until such Preferred Security Certificates are presented to the Security Registrar for transfer or reissuance at which time such Preferred Security Certificates will be cancelled and a Subordinated Debenture, registered in the name of the holder of the Preferred Security Certificate or the transferee of the holder of such Preferred Security Certificate, -4- as the case may be, with an aggregate principal amount equal to the aggregate stated liquidation amount of the Preferred Security Certificate cancelled, will be executed by the Company and delivered to the Trustee for authentication and delivery in accordance with the Indenture and this Second Supplemental Indenture. On issue of such Subordinated Debentures, Subordinated Debentures with an equivalent aggregate principal amount that were presented by the Property Trustee to the Trustee will be deemed to have been cancelled. Section 2.5. Interest. (a) Each Subordinated Debenture will bear interest at the rate of 8.04% per annum (the "Coupon Rate") from the original date of issuance until the principal thereof becomes due and payable, and on any overdue principal and (to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the Coupon Rate, compounded quarterly, payable (subject to the provisions of Article IV) quarterly in arrears on March 31, June 30, September 30 and December 31 of each year (each, an "Interest Payment Date"), commencing on March 31, 1998, to the Person in whose name such Subordinated Debenture or any predecessor Subordinated Debenture is registered, at the close of business on the regular record date for such interest installment, which shall be the close of business on the Business Day next preceding that Interest Payment Date. If pursuant to the provisions of Section 2.11(c) of the Indenture the Subordinated Debentures are no longer represented by a Global Security, the Company may select a regular record date for such interest installment which shall be any date at least fifteen days before an Interest Payment Date. (b) The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the Subordinated Debentures is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. The amount of interest payable for any period shorter than a full quarterly period for which interest is computed, will be computed on the basis of the actual number of days elapsed in such a 90-day quarter. (c) If at any time while the Property Trustee is the holder of any Subordinated Debentures, the Trust or the Property Trustee is required to pay any taxes, duties, assessments or governmental charges of whatever nature (other than withholding taxes) imposed by the United States, or any other taxing authority, then, in any case, the Company will pay as additional interest ("Additional Interest") on the Subordinated Debentures held by the Property Trustee, such additional amounts as shall be required so that the net amounts received and retained by the Trust and the Property Trustee after paying such taxes, duties, assessments or other governmental charges will be equal to the amounts the Trust and the Property Trustee would have received had no such taxes, duties, assessments or other government charges been imposed. -5- ARTICLE III REDEMPTION OF THE SUBORDINATED DEBENTURES Section 3.1. Tax Event Redemption. If a Tax Event has occurred and is continuing and the Company has received a Redemption Tax Opinion, then, notwithstanding Section 3.2(a) but subject to Section 3.2(b), the Company shall have the right upon not less than 30 days' nor more than 60 days' notice to the registered holders of the Subordinated Debentures to redeem the Subordinated Debentures, in whole but not in part, for cash within 90 days following the occurrence of such Tax Event (the "90 Day Period") at a redemption price equal to 100% of the principal amount to be redeemed plus any accrued and unpaid interest thereon to the date of such redemption (the "Redemption Price") provided that, if at the time there is available to the Company the opportunity to eliminate, within the 90 Day Period, the Tax Event by taking some ministerial action ("Ministerial Action"), such as filing a form or making an election, or pursuing some other similar reasonable measure that has no adverse effect on the Company, the Trust or the Holders of the Trust Securities issued by the Trust, the Company shall pursue such Ministerial Action in lieu of redemption; and provided further, that the Company shall have no right to redeem the Subordinated Debentures while the Trust is pursuing any Ministerial Action pursuant to its obligations under the Declaration. The Redemption Price shall be paid prior to 12:00 noon, New York time, on the date of such redemption or at such earlier time as the Company determines and specifies in the notice of redemption, provided the Company shall deposit with the Trustee an amount sufficient to pay the Special Redemption Price by 11:00 a.m. on the date such Redemption Price is to be paid. Section 3.2. Optional Redemption by Company. (a) Subject to the provisions of Article III of the Indenture and to Section 3.2(b), the Company shall have the right to redeem the Subordinated Debentures, in whole or in part, from time to time, on or after March 31, 2003, at the Redemption Price. Any redemption pursuant to this paragraph will be made upon not less than 30 days' nor more than 60 days' notice to the registered holder of the Subordinated Debentures, at the Redemption Price. If the Subordinated Debentures are only partially redeemed pursuant to this Section 3.2, the Subordinated Debentures will be redeemed pro rata or by lot or by any other method utilized by the Trustee; provided, that if at the time of redemption, the Subordinated Debentures are registered as a Global Security, the Depositary shall determine by lot the principal amount of such Subordinated Debentures held by each holder to be redeemed. The Redemption Price shall be paid prior to 12:00 noon, New York time, on the date of such redemption or at such earlier time as the Company determines and specifies in the notice of redemption, provided the Company shall deposit with the Trustee an amount sufficient to pay the Redemption Price by 11:00 a.m. on the date such Redemption Price is to be paid. (b) If a partial redemption of the Subordinated Debentures would result in the delisting of the Preferred Securities issued by the Trust from any national securities exchange or other organization on which the Preferred Securities are then -6- listed, the Company shall not be permitted to effect such partial redemption and may only redeem the Subordinated Debentures in whole. Section 3.3. No Sinking Fund. The Subordinated Debentures are not entitled to the benefit of any sinking fund. ARTICLE IV EXTENSION OF INTEREST PAYMENT PERIOD Section 4.1. Extension of Interest Payment Period. The Company shall have the right, at any time and from time to time during the term of the Subordinated Debentures, to extend the interest payment period of such Subordinated Debentures for up to twenty (20) consecutive quarters (the "Extended Interest Payment Period"); provided, that, during any such Extended Interest Payment Period, (a) the Company may not declare or pay any dividend on, make any distributions with respect to, or redeem, purchase or acquire, or make a liquidation payment with respect to, any of its capital stock (other than (i) purchases or acquisitions of shares of Company common stock in connection with the satisfaction by the Company of its obligations under any employee benefit plans or any other contractual obligation of the Company (other than a contractual obligation ranking pari passu with or junior to the Subordinated Debentures), (ii) as a result of a reclassification of Company capital stock or the exchange or conversion of one class or series of Company capital stock for another class or series of Company capital stock or (iii) the purchase of fractional interests in shares of Company capital stock pursuant to the conversion or exchange provisions of such Company capital stock or the security being converted or exchanged), (b) the Company may not make any payment of interest, principal or premium, if any, on or repay, repurchase or redeem any debt securities (including guarantees) issued by the Company which rank pari passu with or junior to the Subordinated Debentures and (c) the Company may not make any guarantee payments with respect to the foregoing (other than pursuant to the Preferred Securities Guarantee). To the extent permitted by applicable law, interest, the payment of which has been deferred because of the extension of the interest payment period pursuant to this Section 4.1, will bear interest compounded quarterly at the Coupon Rate for each quarter of the Extended Interest Payment Period ("Compounded Interest"). At the end of the Extended Interest Payment Period, the Company shall pay all interest accrued and unpaid on the Subordinated Debentures, including any Compounded Interest and Additional Interest ("Deferred Interest") which shall be payable to the holders of the Subordinated Debentures in whose names the Subordinated Debentures are registered in the Security Register on the first record date after the end of the Extended Interest Payment Period. Prior to the termination of any Extended Interest Payment Period, the Company may further extend such period, provided that such period together with all such further extensions thereof shall not exceed twenty (20) consecutive quarters or extend beyond the maturity of the Subordinated Debentures. Upon the termination of any Extended Interest Payment Period and upon the payment of all Deferred Interest then due, the Company may select a new Extended Interest Payment Period, subject to the foregoing requirements. No interest shall be due and payable during an Extended Interest Payment Period, except at the end thereof. Section 4.2. Notice of Extension. (a) If the Property Trustee is the only registered -7- holder of the Subordinated Debentures at the time the Company selects an Extended Interest Payment Period, the Company shall give written notice to both the Regular Trustees and the Property Trustee of its selection of such Extended Interest Payment Period one Business Day before the earlier of (i) the next succeeding date on which Distributions on the Trust Securities issued by the Trust are payable, or (ii) the date the Trust is required to give notice of the record or payment date for such Distributions to the New York Stock Exchange or other applicable self-regulatory organization or to holders of the Preferred Securities issued by the Trust, but in any event at least one Business Day before such record date. (b) If the Property Trustee is not the only holder of the Subordinated Debentures at the time the Company selects an Extended Interest Payment Period, the Company shall give the holders of the Subordinated Debentures and the Trustee written notice of its selection of such Extended Interest Payment Period ten (10) Business Days before the earlier of (i) the next succeeding Interest Payment Date, or (ii) the date the Company is required to give notice of the record or payment date of such interest payment to the New York Stock Exchange or other applicable self-regulatory organization or to holders of the Subordinated Debentures, but in any event at least two Business Days before such record date. (c) The quarter in which any notice is given pursuant to paragraphs (a) or (b) of this Section 4.2 shall be counted as one of the twenty quarters permitted in the maximum Extended Interest Payment Period permitted under Section 4.1. ARTICLE V EXPENSES Section 5.1. Payment of Expenses. In connection with the offering, sale and issuance of the Subordinated Debentures to the Property Trustee in connection with the sale of the Trust Securities by the Trust, the Company shall: (a) pay all costs and expenses relating to the offering, sale and issuance of the Subordinated Debentures, including commissions to the underwriters payable pursuant to the Underwriting Agreement and compensation of the Trustee under the Indenture in accordance with the provisions of Section 7.06 of the Indenture; (b) pay all costs and expenses of the Trust (including, but not limited to, costs and expenses relating to the organization of the Trust, the offering, sale and issuance of the Trust Securities (including commissions to the underwriters in connection therewith), the fees and expenses of the Property Trustee and the Delaware Trustee, the costs and expenses relating to the operation of the Trust, including without limitation, costs and expenses of accountants, attorneys, statistical or -8- bookkeeping services, expenses for printing and engraving and computing or accounting equipment, paying agent(s), registrar(s), transfer agent(s), duplicating, travel and telephone and other telecommunications expenses and costs and expenses incurred in connection with the acquisition, financing, and disposition of Trust assets); and (c) pay any and all taxes (other than United States withholding taxes) and all liabilities, costs and expenses with respect to such taxes of the Trust. ARTICLE VI SUBORDINATION Section 6.1. Agreement to Subordinate. The Company covenants and agrees, and each holder of Subordinated Debentures issued hereunder by such holder's acceptance thereof likewise covenants and agrees, that all Subordinated Debentures shall be issued subject to the provisions of this Article VI; and each holder of a Subordinated Debenture, whether upon original issue or upon transfer or assignment thereof, accepts and agrees to be bound by such provisions. The payment by the Company of the principal of, premium, if any, and interest on all Subordinated Debentures issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full of all Senior Indebtedness of the Company, whether outstanding at the date of this Second Supplemental Indenture or thereafter incurred. No provision of this Article VI shall prevent the occurrence of any default or Event of Default hereunder. Section 6.2. Default on Senior Indebtedness. In the event and during the continuation of any default by the Company in the payment of principal, premium, interest or any other payment due on any Senior Indebtedness of the Company, or in the event that the maturity of any Senior Indebtedness of the Company has been accelerated because of a default, then, in either case, no payment shall be made by the Company with respect to the principal (including redemption payments) of, or premium, if any, or interest on the Subordinated Debentures. In the event that, notwithstanding the foregoing, any payment shall be received by the Trustee or any holder of Subordinated Debentures when such payment is prohibited by the preceding paragraph of this Section 6.2, such payment shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of Senior Indebtedness or their respective representatives, or to the trustee or trustees under any indenture pursuant to which any of such Senior Indebtedness may have been issued, as their respective interests may appear, but only to the extent that the holders of the Senior Indebtedness (or their representative or representatives or a trustee) notify the Trustee within 90 -9- days of such payment of the amounts then due and owing on the Senior Indebtedness and only the amounts specified in such notice to the Trustee shall be paid to the holders of Senior Indebtedness. Section 6.3. Liquidation; Dissolution; Bankruptcy. Upon any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, all amounts due upon all Senior Indebtedness shall first be paid in full, or payment thereof provided for in money in accordance with its terms, before any payment is made by the Company on account of the principal (and premium, if any) or interest on the Subordinated Debentures; and upon any such dissolution or winding-up or liquidation or reorganization, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the holders of the Subordinated Debentures or the Trustee would be entitled to receive from the Company, except for the provisions of this Article VI, shall be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the holders of the Subordinated Debentures or by the Trustee under this Indenture if received by them or it, directly to the holders of Senior Indebtedness of the Company (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, as calculated by the Company) or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing such Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay such Senior Indebtedness in full, in money or money's worth, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness, before any payment or distribution is made to the holders of Subordinated Debentures or to the Trustee. In the event that, notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, prohibited by the foregoing, shall be received by the Trustee or the holders of the Subordinated Debentures before all Senior Indebtedness of the Company is paid in full, or provision is made for such payment in money in accordance with its terms, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of such Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing such Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness of the Company remaining unpaid to the extent necessary to pay such Senior Indebtedness in full in money in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the benefit of the holders of such Senior Indebtedness. For purposes of this Article VI, the words "cash, property or securities" shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article VI with respect to the Subordinated Debentures to the payment of all Senior Indebtedness of the Company that may at the time be outstanding, provided that (i) such Senior Indebtedness is assumed by the new corporation, if any, resulting from any such reorganization or readjustment, and (ii) the rights of the holders of such Senior Indebtedness -10- are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article X of the Indenture shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 6.3 if such other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article X of the Indenture. Nothing in Section 6.2 or in this Section 6.3 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 7.06 of the Indenture. Section 6.4. Subrogation. Subject to the payment in full of all Senior Indebtedness of the Company, the rights of the holders of the Subordinated Debentures shall be subrogated to the rights of the holders of such Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company applicable to such Senior Indebtedness until the all amounts owing on the Subordinated Debentures shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of such Senior Indebtedness of any cash, property or securities to which the holders of the Subordinated Debentures or the Trustee would be entitled except for the provisions of this Article VI, and no payment over pursuant to the provisions of this Article VI, to or for the benefit of the holders of such Senior Indebtedness by holders of the Subordinated Debentures or the Trustee, shall, as between the Company, its creditors other than holders of Senior Indebtedness of the Company, and the holders of the Subordinated Debentures be deemed to be a payment by the Company to or on account of such Senior Indebtedness. It is understood that the provisions of this Article VI are and are intended solely for the purposes of defining the relative rights of the holders of the Subordinated Debentures, on the one hand, and the holders of such Senior Indebtedness on the other hand. Nothing contained in this Article VI or elsewhere in this Indenture or in the Subordinated Debentures is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Indebtedness of the Company, and the holders of the Subordinated Debentures, the obligation of the Company which is absolute and unconditional, to pay to the holders of the Subordinated Debentures the principal of (and premium, if any) and interest on the Subordinated Debentures as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the holders of the Subordinated Debentures and creditors of the Company, other than the holders of Senior Indebtedness of the Company, nor shall anything herein or therein prevent the Trustee or the holder of any Subordinated Debenture from exercising all remedies otherwise permitted by applicable law upon default under the Indenture, subject to the rights, if any, under this Article VI of the holders of such Senior Indebtedness in respect of cash, property or securities of the Company, received upon the exercise of any such remedy. Upon any payment or distribution of assets of the Company referred to in this Article VI, the Trustee, subject to the provisions of Section 7.01 of the Indenture, and the holders of the Subordinated Debentures, shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent or other Person making such payment or distribution, delivered to the Trustee or to the holders of the Subordinated Debentures, for the purposes of ascertaining the Persons entitled to participate in such distribution, the holders of -11- Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article VI. Section 6.5. Trustee to Effectuate Subordination. Each holder of a Subordinated Debenture by such holder's acceptance thereof authorizes and directs the Trustee on such holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article VI and appoints the Trustee such holder's attorney-in-fact for any and all such purposes.

The Company shall give prompt written notice to a Responsible Officer of the Trustee of any fact known to the Company that would prohibit the making of any payment of monies to or by the Trustee in respect of the Subordinated Debentures pursuant to the provisions of this Article VI. Notwithstanding the provisions of this Article VI or any other provision of the Indenture and this Second Supplemental Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment of monies to or by the Trustee in respect of the Subordinated Debentures pursuant to the provisions of this Article VI unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the Principal Office of the Trustee from the Company or a holder or holders of Senior Indebtedness or from any trustee therefor; and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 7.01 of the Indenture, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section 6.6 at least two Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal of (or premium, if any) or interest on any Subordinated Debenture), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purposes for which they were received, and shall not be affected by any notice to the contrary that may be received by it within two Business Days prior to such date.

The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article VI in respect of any Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. -12- With respect to the holders of Senior Indebtedness of the Company, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article VI, and no implied covenants or obligations with respect to the holders of such Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of such Senior Indebtedness and, subject to the provisions of Section 7.01 of the Indenture, the Trustee shall not be liable to any holder of such Senior Indebtedness if it shall pay over or deliver to holders of Subordinated Debentures, the Company or any other Person money or assets to which any holder of such Senior Indebtedness shall be entitled by virtue of this Article VI or otherwise. Section 6.8. Subordination May Not Be Impaired. No right of any present or future holder of any Senior Indebtedness of the Company to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of the Indenture, regardless of any knowledge thereof that any such holder may have or otherwise be charged with. Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness of the Company may, at any time and from time to time, without the consent of or notice to the Trustee or the holders of the Subordinated Debentures, without incurring responsibility to the holders of the Subordinated Debentures and without impairing or releasing the subordination provided in this Article VI or the obligations hereunder of the holders of the Subordinated Debentures to the holders of such Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, such Senior Indebtedness, or otherwise amend or supplement in any manner such Senior Indebtedness or any instrument evidencing the same or any agreement under which such Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing such Senior Indebtedness; (iii) release any Person liable in any manner for the collection of such Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Company and any other Person.

By the terms of the Indenture, the Subordinated Debentures are issuable in series which may vary as to amount, date of maturity, rate of interest and in other respects as in the Indenture provided. This series of Subordinated Debentures is limited in aggregate principal amount as specified in said Second Supplemental Indenture. Upon the occurrence and continuation of a Tax Event, in certain circumstances this Subordinated Debenture will become due and payable at the principal amount together with any interest accrued thereon (the "Redemption Price"). The Redemption Price shall be paid prior to 12:00 noon, New York time, on the date of such redemption or at such earlier time as the Company determines. The Company shall have the -18- right to redeem this Subordinated Debenture at the option of the Company, without premium or penalty, in whole or in part at any time on or after March 31, 2003 (an "Optional Redemption"), at the Redemption Price. Any Optional Redemption pursuant to this paragraph will be made upon not less than 30 days' nor more than 60 days' notice, at the Redemption Price. If the Subordinated Debentures are only partially redeemed by the Company pursuant to an Optional Redemption, the Subordinated Debentures will be redeemed pro rata or by lot or by any other method utilized by the Trustee; provided that if at the time of redemption, the Subordinated Debentures are registered as a Global Security, the Depositary shall determine by lot the principal amount of such Subordinated Debentures held by each holder to be redeemed. In the event of redemption of this Subordinated Debenture in part only, a new Subordinated Debenture or Subordinated Debentures of this series for the unredeemed portion hereof will be issued in the name of the holder hereof upon the cancellation hereof. In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Subordinated Debentures may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Subordinated Debentures of each series affected at the time Outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the holders of the Subordinated Debentures; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Subordinated Debentures of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, without the consent of the holder of each Subordinated Debenture so affected or (ii) reduce the aforesaid percentage of Subordinated Debentures, the holders of which are required to consent to any such supplemental indenture, without the consent of the holders of each Subordinated Debenture then outstanding and affected thereby. The Indenture also contains provisions permitting the holders of a majority in aggregate principal amount of the Subordinated Debentures of any series at the time outstanding affected thereby, on behalf of all of the holders of the Subordinated Debentures of such series, to waive any past default in the performance of any of the covenants contained in the Indenture, or established pursuant to the Indenture with respect to such series, and its consequences, except a default in the payment of the principal of or premium, if any, or interest on any of the Subordinated Debentures of such series. Any such consent or waiver by the registered holder of this Subordinated Debenture (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Subordinated Debenture and of any Subordinated Debenture issued in exchange herefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Subordinated Debenture. No reference herein to the Indenture and no provision of this Subordinated Debenture or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if -19- any, and interest on this Subordinated Debenture at the time and place and at the rate and in the money herein prescribed. The Company shall have the right at any time during the term of the Subordinated Debentures, from time to time to extend the interest payment period of such Subordinated Debentures for up to twenty (20) consecutive quarters (an "Extended Interest Payment Period"), at the end of which period the Company shall pay all interest then accrued and unpaid (together with interest thereon at the rate specified for the Subordinated Debentures to the extent that payment of such interest is enforceable under applicable law). Before the termination of any such Extended Interest Payment Period, the Company may further extend such Extended Interest Payment Period, provided that such Extended Interest Payment Period together with all such further extensions thereof shall not exceed twenty (20) consecutive quarters or extend beyond the maturity of the Subordinated Debentures. At the termination of any such Extended Interest Payment Period and upon the payment of all accrued and unpaid interest then due, the Company may select a new Extended Interest Payment Period.

No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto. Prior to due presentment for registration of transfer of this Subordinated Debenture, the Company, the Trustee, any paying agent and any Security Registrar may deem and treat the registered holder hereof as the absolute owner hereof (whether or not this Subordinated Debenture shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Security Registrar shall be affected by any notice to the contrary. No recourse shall be had for the payment of the principal of or the interest on this Subordinated Debenture, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past, present or future, as such, of the Company or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.
