        All Securities presented for registration of transfer or for exchange or payment shall (if so required by the Corporation or the Registrar) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Corporation and the Security registrar duly executed by, the holder or his attorney duly authorized in writing.

        The Corporation may at any time and in its sole discretion determine that the Securities of any series issued in the form of a Global Security shall no longer be represented by such Global Security. In such event the Corporation will execute, and the Trustee, upon receipt of the Corporation's written order for the authentication and delivery of definitive Securities of such series, will authenticated and deliver, in exchange for such Global Security, Securities of such series in definitive form in authorized denominations, in an aggregate principal amount equal to the principal amount of the Securities no longer to be represented by such Global Security and having like terms and conditions.

In every case the applicant for a substituted Security shall furnish to the Corporation, to the Security registrar, any paying agent and to the Trustee such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Corporation, to the Security registrar, to any paying agent and to the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof.

        The Trustee may authenticate any substituted Security and deliver the same upon the written request or authorization of any officer of the Corporation. Upon the issuance of any substituted Security, the Corporation may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses, including counsel fees of the Corporation, the Trustee, any paying agent or Security registrar connected therewith. In case any Security which has matured or is about to mature shall become mutilated or be destroyed, lost or stolen, the Corporation may, instead of issuing a substitute Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Security) if the applicant for such payment shall furnish to the Corporation, to the Security registrar, any paying agent and to the Trustee such security or indemnity as may be required by them to save each of them harmless and, in case of destruction, loss or theft, evidence satisfactory to the Corporation, the Security registrar and the Trustee of the destruction, loss or theft of such Security and of the ownership thereof.

        Every substituted Security issued pursuant to the provisions of this Section 3.05 by virtue of the fact that any Security is destroyed, lost or stolen shall constitute an additional contractual obligation of the Corporation, whether or not the destroyed, lost or stolen Security shall be enforceable at any time, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. All Securities shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities and shall preclude to the extent permitted by law any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

        Section 3.06.    Temporary Securities.    Pending the preparation of permanent Securities of any series, the Corporation may execute and the Trustee shall authenticate and deliver temporary Securities (printed or lithographed) of such series. Temporary Securities of any series shall be issuable in any

10

---

authorized denomination, and substantially in the form of the permanent Securities of such series, but with such omissions, insertions and variations as may be appropriate for temporary Securities of such series, all as may be determined by the Corporation. Every such temporary Security shall be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the permanent Securities of such series. Without unreasonable delay the Corporation will execute and deliver to the Trustee permanent Securities of such series and thereupon any or all temporary Securities of such series may be surrendered in exchange therefore at the Corporate Office of the Trustee or at any agency to be maintained by the Corporation for such purpose as provided in Section 5.02, and the Trustee shall authenticate and deliver in exchange for such temporary Securities an equal aggregate principal amount of permanent Securities of such series. Such exchange shall be made by the Corporation at its own expense and without any charge therefore except that the Corporation may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under, and be subject to the terms and conditions of, this Indenture as permanent Securities of the same series authenticated and delivered hereunder.

        Section 3.07.    Cancellation of Securities Paid, etc.    All Securities surrendered for the purpose of payment, exchange or registration of transfer shall, if surrendered to the Corporation or any agent for exchange and registration of transfer, be surrendered to the Trustee for cancellation and promptly cancelled by it, or, if surrendered to the Trustee, shall be promptly cancelled by it, and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of such cancelled securities in its customary manner. If the Corporation shall acquire any of the Securities, however, such acquisition shall not operate as a satisfaction of the indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation.

        Section 3.08.    Cusip Numbers.    The Corporation in issuing the Securities may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to Securityholders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Corporation will promptly notify the Trustee of any change in the "CUSIP" numbers.

        Section 3.09.    Transfers And Exchange Of Global Securities.    Notwithstanding any provisions to the contrary set forth in this Article One hereof, the following terms and conditions shall govern the transfer and exchange of the Securities.

Except as otherwise set forth in the form of Security for such series, each Security shall be subject to partial redemption only in the amount of $1,000 or integral multiples of $1,000.

        Section 4.02.    Election to Redeem: Notices to Trustee.    The election of the Corporation to redeem any Securities shall be evidenced by or pursuant to a Board Resolution.

The Trustee shall promptly notify the Corporation in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

        If any Convertible Security selected for partial redemption by the Trustee pursuant to Section 4.03 is converted in part before termination of the conversion right with respect to the portion of the Convertible Security so selected, the converted portion of such Convertible Security will be deemed (so far as may be) to be the portion selected for redemption. Convertible Securities which have been converted during a selection of Convertible Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such Conversion.

        Section 4.04.    Notice of Redemption.    Notice of redemption shall be given by first-class mail, postage prepaid, mailed not later than the thirtieth day, and not earlier than the sixtieth day, prior to the date fixed for redemption, to each holder of Securities to be redeemed, at his address as it appears on the registry books of the Corporation.

        (a)   the identity of the securities, including cusip numbers;

        (b)   the date fixed for redemption for Securities of such series;

        (c)   the redemption price at which Securities of such series are to be redeemed;

        (d)   if less than all outstanding Securities of such particular series are to be redeemed, the identification (and, in the case of partial redemption, the respective principal amounts) of the particular Securities to be redeemed;

        (e)   that on the date fixed for redemption, the redemption price at which such Securities are to be redeemed will become due and payable upon each such Security or portion thereof, and that interest thereon, if any, shall cease to accrue on and after said date;

where the Securities may be presented for registration of transfer and exchange as in this Indenture provided and where notices or demands to or upon the Corporation in respect of the Securities or of this Indenture may be served. The Corporation hereby initially appoints the Trustee as its agent for all such purposes until otherwise designated by the Corporation in a written notice to the Trustee, the office or agency for all such purposes shall be the Corporate Office of the Trustee. In case the Corporation shall at any time designate a different office or agency for such purposes, but shall fail to maintain such office or agency, or shall fail to give notice to the Trustee of any change in the location thereof, presentation and demand may be made and notices may be served, in respect of the Securities or of this Indenture, at the Principal Office of the Trustee, and the Corporation hereby appoints the Trustee its agent to receive all such presentations, surrenders, notices and demands.

        In addition to any such office or agency the Corporation may from time to time constitute and appoint one or more paying agents for the payment of such Securities, in one or more other cities, and may from time to time rescind such appointments, as the Corporation may deem desirable or expedient.

          (i)  that it will hold all sums held by it as such paying agent for the payment of the principal of (and premium, if any) or interest, if any, on such Securities in trust for the benefit of the holders of the Securities entitled thereto, or for the benefit of the Trustee, as the case may be, until such sums shall be paid out to such holders or otherwise as herein provided;

         (ii)  that it will give the Trustee notice of any failure by the Corporation in the making of any deposit with such paying agent for the payment of principal of (and premium, if any) or interest, if any, on such Securities which shall have become payable and of any Default by the Corporation in making any payment of the principal of (and premium, if any) or interest on such Securities when the same shall be due and payable, and

        (iii)  that it will at any time during the continuance of any such Default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such paying agent.

        (b)   If the Corporation shall act as its own paying agent as to any series of Securities, it will, on or before each due date of the principal of (and premium, if any) or interest, if any, on such Securities, set aside and hold in trust for the benefit of the holders of such Securities entitled thereto a sum sufficient (together with any sums deposited with any other paying agent for such purpose) to pay such principal (and premium, if any) or interest, if any, so becoming due and will notify in writing the Trustee of any, failure by it to take such action. Whenever the Corporation shall have one or more paying agents with respect to any particular series of Securities, it will, on or before each due date of the principal of (and premium, if any) or interest if any on the Securities, deposit with a paying agent a sum sufficient to pay such principal (and premium, if any) or interest so becoming due, such sums to be held in trust for the benefit of the holders of such Securities entitled thereto, and (unless the paying agent is the Trustee) the Corporation will notify in writing the Trustee of failure by it to take such action.

        (c)   Anything in this Section 5.04 to the contrary notwithstanding, the Corporation may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture, or for any other

22

purpose, pay or cause to be paid to the Trustee all sums held in trust by the Corporation or any paying agent as required by this Section 5.04, such sums to be held by the Trustee upon the trusts herein contained.

        (d)   Anything in this Section 5.04 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 5.04 is subject to the provisions of Sections 13.03 and 13.04.

        (d)   the entry of a decree or order by a court having jurisdiction in the premises granting relief in respect of the Corporation in an involuntary case under the Federal Bankruptcy Code adjudging the Corporation a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Corporation under the Federal Bankruptcy Code or any other applicable Federal or State law, or appointing a receiver, liquidator, custodian, assignee, trustee, sequestrator (or other similar official) of the Corporation, or of any substantial part of the respective properties of either, or ordering the winding up or liquidation of the affairs of either, and the continuance of any such decree or order unstayed and in effect for a period of 120 days; or

        In case one or more of the Events of Default specified above shall have occurred and be continuing with respect to any particular series of Securities, then and in each and every such case, unless the principal of all of the Securities of that series shall have already become due and payable, either the Trustee or the holders of not less than thirty-three percent in aggregate principal amount of the Securities of that series then outstanding hereunder, by notice in writing to the Corporation (and to the Trustee if given by Securityholders), may declare the principal or, in the case of Discounted Securities, such amount of principal as may be provided for in such Securities, of all the Securities of that series to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Securities of that series contained to the contrary notwithstanding.

rescind and annul such declaration and its consequences; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default, or shall impair any right consequent thereon.

        In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Trustee, then and in every such case the Corporation and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Corporation and the Trustee shall continue as though no such proceeding had been taken.

        Section 7.02.    Payment of Securities on Default; Suit Therefor.    The Corporation covenants that (a) in case Default shall be made in the payment of any installment of interest upon any of the Securities of any series as and when the same shall become due and payable, and such Default shall have continued for a period of thirty days, or (b) in case Default shall be made in the payment of the principal of (or premium, if any, on) any of the Securities of any series as and when the same shall have become due and payable, whether at maturity of the Securities of that series or by declaration or otherwise, then, upon demand of the Trustee, the Corporation will pay to the Trustee, for the benefit of the holders of such Securities, the whole amount that then shall have become due and payable on all such Securities for principal (and premium, if any) or interest, if any, with interest upon the overdue principal (and premium, if any) and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest at the rate of interest (or the Yield to Maturity in the case of Discounted Securities) borne by the Securities of that series; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, and any expenses or liabilities incurred, and all advances made, by the Trustee hereunder other than through its negligence or willful misconduct.

        In case the Corporation shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Corporation or any other obligor on such Securities and collect in the manner provided by law out of the property of the Corporation or any other obligor on such Securities wherever situated the moneys adjudged or decreed to be payable. In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Corporation or any other obligor on the Securities of any series under the Federal Bankruptcy Code or any other applicable law, or in case a receiver, custodian or trustee shall have been appointed for the property of the Corporation or such other obligor, or in the case of any similar judicial proceedings relative to the Corporation or other obligor upon such Securities, or to the creditors or property of the Corporation or such other obligor, the Trustee, irrespective of whether the principal of such Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 7.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims, for the whole amount of principal (and premium, if any) and interest, if any owing and unpaid in respect of such Securities, and in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the holders of such Securities allowed in such judicial proceedings relative to the Corporation or any other obligor on such Securities, its or their creditors, or its or their property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute the same after the deduction of its charges and expenses; and any receiver, custodian, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of the Securityholders to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such

        SECOND: In case the principal of the outstanding Securities in respect of which moneys have been collected shall not have become due and be unpaid, to the payment of interest, if any, on such Securities, in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the rate of interest (or the Yield to Maturity in the case of Discounted Securities) borne by such Securities, such payments to be made ratably to the persons entitled thereto;

        THIRD: In case the principal of the outstanding Securities in respect of which moneys have been collected shall have become due, by declaration or otherwise, to the payment of the whole amount then owing and unpaid upon such Securities for principal (and premium, if any) and interest, if any, with interest on the overdue principal (and premium, if any) and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate of interest (or the Yield to Maturity in the case of Discounted Securities) borne by such Securities; and in case such moneys shall be insufficient to pay in full the whole amounts so due and unpaid upon such Securities, then to the payment of such principal (and premium, if any) and interest without preference or priority of principal (and premium, if any) over interest, or of interest over principal (and premium, if any) or of any installment of interest over any other installment of interest, or of any such Security over any other such Security, ratably to the aggregate of such principal (and premium, if any) and accrued and unpaid interest; and,

        FOURTH: To the payment of the remainder, if any, to the Corporation, its successors or assigns, or to whomsoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct.

action, suit or proceeding, it being understood and intended, and being expressly covenanted by the taker and holder of every Security with every other taker and holder and the Trustee, that no one or more holders of Securities of that series shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the right of any other holder of such Securities, or to obtain or seek to obtain priority over or preference to any such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Securities of that series.

        Notwithstanding any other provisions in this Indenture, the right of any holder of any Security to receive payment of the principal of (and premium, if any) and interest, if any, on such Security, on or after the respective due dates expressed in such Security, or to institute suit for the enforcement of any such payment on or after such respective dates shall not be impaired or affected without the consent of such holder.

        Section 7.05.    Proceedings by Trustee.    In case of an Event of Default hereunder the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

        Section 7.06.    Remedies Cumulative and Continuing.    All powers and remedies given by this Article 7 to the Trustee or to the Securityholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Securities, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of the Securities to exercise any right or power accruing upon any Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such Default or an acquiescence therein; and, subject to the provisions of Section 7.04, every power and remedy given by this Article 7 or by law to the Trustee or to the Securityholders may be exercised from time to time and as often as may be deemed expedient by the Trustee or by the Securityholders.

        Section 7.07.    Direction of Proceedings and Waiver of Defaults by Majority of Securityholders.    The holders of a majority in aggregate principal amount of the Securities of any series at the time outstanding determined in accordance with Section 9.04 shall have the right to direct the time, method, and place of conducting any proceedings for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of that series; provided, however, that (subject to the provisions of Section 8.01) the Trustee shall have the right to decline to follow any such direction if the Trustee being advised by counsel determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by a trust committee of Responsible Officers shall determine that the action or proceedings so directed would involve the Trustee in personal liability. Prior to any declaration accelerating the maturity of the Securities of any series, the holders of a majority in aggregate principal amount of the Securities determined in accordance with Section 9.04 of that series at the time outstanding may on behalf of the holders of all Securities of that series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of the principal of (or premium, if any) or interest on the Securities of that series. Upon any such waiver the Corporation, the Trustee and the holders of such Securities shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 7.07, said Default or Event of Default shall for all Purposes of the Securities of such series and this Indenture with respect to such Securities be deemed to have been cured and to be not continuing.

        (b)   to add to the covenants of the Corporation such further covenants, restrictions or conditions for the protection of the holders of the Securities as the Board of Directors and the Trustee shall consider to be for the protection of the holders of Securities, and to make the occurrence, or the occurrence and continuance, of a Default in any of such additional covenants, restrictions or conditions a Default or an Event of Default permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set forth; provided, however, that in respect of any such additional covenant, restriction or condition such supplemental indenture may provide for a particular period of grace after Default (which period may be shorter or longer than that allowed in the case of other Defaults) or may provide for an immediate enforcement upon such Default or may limit the remedies available to the Trustee upon such Default;

        (c)   to provide for the issuance under this Indenture of Securities in coupon form (including Securities registrable as to principal only) and to provide for exchangeability of such Securities with the Securities of the same series issued hereunder in fully registered form and to make all appropriate changes for such purpose;

        (d)   to cure any ambiguity or to correct or supplement any provision contained herein or in any supplemental indenture which may be defective or inconsistent with any other provision contained herein or in any supplemental indenture or to make such other provisions in regard to matters or questions arising under this Indenture which shall not adversely affect the interest of the holders of the Securities;

provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the Trusts hereunder by more than one Trustee, pursuant to the requirements of Section 8.11 hereof; or

        (g)   to provide for conversion rights of Securityholders pursuant to Section 16.11 of this Indenture.

        The Trustee is hereby authorized to join with the Corporation in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer and assignment of any property thereunder, but the Trustee shall not be obligated to, but may in its discretion, enter into any such supplemental indenture which affects the Trustee's own rights, duties or immunities under this Indenture or otherwise.

        Any supplemental indenture authorized by the provisions of this Section 11.01 may be executed by the Corporation and the Trustee without the consent of the holders of any of the Securities at the time outstanding, notwithstanding any of the provisions of Section 11.02.

        Section 11.02.    Supplemental Indentures with Consent of Securityholders.    With the consent (evidenced as provided in Section 9.01) of the holders of not less than 66²/3% in aggregate principal amount of the Securities of all series affected by such supplemental indenture (voting as one class) at the time outstanding, the Corporation, when authorized by a resolution of the Board of Directors, and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the holders of the Securities of each such series; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Security, or reduce the rate or change the method to be used in establishing the rate or extend the time of payment of interest thereon, or reduce the principal amount thereof, or reduce any premium payable upon the redemption thereof, or reduce the amount of the principal of a Discounted Security that would be due and payable upon a declaration of acceleration of the maturity thereof pursuant to Section 7.01, or make the principal thereof or premium or interest thereon payable in any coin or currency other than that provided in such Securities, without the consent of the holder of each Security so affected, or (ii) reduce the aforesaid percentage of Securities, the holders of which are required to consent to any such supplemental indenture, without the consent of the holders of all Securities of the series affected then outstanding. A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the holders of Securities of any other series.

        Upon the request of the Corporation, accompanied by a Board Resolution authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Securityholders as aforesaid, the Trustee shall join with the Corporation in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

        It shall not be necessary for the consent of the Securityholders under this Section 11.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof.

        Section 11.03.    Compliance with Trust Indenture Act; Effect of Supplemental Indenture.    Any supplemental indenture executed pursuant to the provisions of this Article 11 shall comply with the Trust Indenture Act of 1939, as then in effect. Upon the execution of any supplemental indenture

pursuant to the provisions of this Article 11, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Corporation and the holders of Securities of the series affected shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

        Section 11.04.    Notation on Securities.    Securities authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 11 may bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Corporation shall so determine, new Securities so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture, may be prepared and executed by the Corporation, authenticated by the Trustee and delivered in exchange for the Securities then outstanding.

        Section 11.05.    Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee.    The Trustee, subject to the provisions of Sections 8.01 and 8.02, shall receive an Officers' Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 11.

ARTICLE 12
CONSOLIDATION, MERGER AND SALE

        Section 12.01.    Corporation May Consolidate, etc., on Certain Terms.    Nothing contained in this Indenture or in any of the Securities shall prevent any consolidation or merger of the Corporation with or into any other corporation or corporations (whether or not affiliated with the Corporation), or successive consolidations or mergers in which the Corporation or its successor or successors shall be a party or parties, or shall prevent any sale or conveyance of all or substantially all the property of the Corporation to any other corporation (whether or not affiliated with the Corporation) authorized to acquire and operate the same; provided, however, and the Corporation hereby covenants and agrees, that upon any such consolidation, merger, sale or conveyance, the due and punctual payment of the principal of (and premium, if any) and interest, if any, on all of the Securities, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed by the Corporation, shall be expressly assumed by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee, by the corporation (if other than the Corporation) formed by such consolidation, or into which the Corporation shall have been merged, or by the corporation which shall have acquired such property.

        Section 12.02.    Successor Corporation to Be Substituted.    In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor corporation, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of (and premium, if any) and interest, if any, on all of the Securities and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Corporation, such successor corporation shall succeed to and be substituted for the Corporation, with the same effect as if it had been named herein as the Corporation. Such successor corporation thereupon may cause to be signed, and may issue either in its own name or in the name of Constellation Energy Group, Inc. any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Corporation and delivered to the Trustee; and, upon the order of such successor corporation instead of the Corporation and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities which previously shall have been signed and delivered by the officers of the Corporation to the Trustee for authentication, and any Securities which such successor corporation thereafter shall cause to be signed

40

and delivered to the Trustee for that purpose. All the Securities of a particular series so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities of such series theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof.

        Nothing contained in this Indenture or in any of the Securities shall prevent the Corporation from merging into itself any other corporation (whether or not affiliated with the Corporation) or acquiring by purchase or otherwise all or any part of the property of any other corporation (whether or not affiliated with the Corporation), provided that, immediately after such merger or acquisition, the Corporation shall not be in Default in the performance or observance of any of the terms, covenants and conditions of this Indenture to be kept or performed by it.

        Section 12.03.    Opinion of Counsel to Be Given to Trustee.    The Trustee, subject to Sections 8.01 and 8.02, shall receive an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale or conveyance and any such assumption complies with the provisions of this Article.

ARTICLE 13
SATISFACTION AND DISCHARGE

        Section 13.01.    Satisfaction and Discharge of Indenture.    When (a) the Corporation shall deliver to the Trustee for cancellation all Securities theretofore authenticated (other than any Securities which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 3.05) and not theretofore cancelled, or (b) all the Securities not theretofore delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year and the Corporation shall deposit with the Trustee or any paying agent, in trust, funds sufficient to pay at maturity all of the Securities (other than any Securities which shall have been mutilated, destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 3.05) not theretofore delivered to the Trustee for cancellation, including principal (and premium, if any) and interest, if any, due or to become due to such date of maturity, but excluding, however, the amount of any moneys for the payment of the principal of (and premium, if any) or interest, if any, on the Securities (i) theretofore deposited with the Trustee or any paying agent and repaid by the Trustee or any paying agent to the Corporation in accordance with the provisions of Section 13.04, or (ii) paid to any State or to the District of Columbia pursuant to its unclaimed property or similar laws, and if in either case the Corporation shall also pay or cause to be paid all other sums payable hereunder by the Corporation, then this Indenture shall cease to be of further effect, and the Trustee, on demand of the Corporation accompanied by an Officers' Certificate and an Opinion of Counsel as required by Section 17.05 and at the cost and expense of the Corporation, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture. The Corporation, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee in connection with this Indenture or the Securities.

        Section 13.02.    Deposited Moneys to Be Held in Trust by Trustee.    All moneys deposited with the Trustee or any paying agent pursuant to Section 13.01 shall be held in trust and applied by it to the payment, either directly or through any paying agent (including the Corporation if acting as its own paying agent), to the holders of the particular Securities for the payment of which such moneys have been deposited with the Trustee, or any paying agent, of all sums due and to become due thereon for principal (and premium, if any) and interest. All moneys deposited with the Trustee or any paying agent pursuant to Section 13.01 for the payment of Convertible Securities subsequently converted will be returned to the Corporation upon Corporation Request.

        Section 13.03.    Paying Agent to Repay Moneys Held.    Upon the satisfaction and discharge of this Indenture all moneys then held by any paying agent of the Securities (other than the Trustee) shall, upon demand of the Corporation, be repaid to it or paid to the Trustee, and thereupon such paying agent shall be released from all further liability with respect to such moneys.

        Section 13.04.    Return of Unclaimed Moneys.    Any moneys deposited with or paid to the Trustee for payment of the principal of (or premium, if any) or interest on Securities of any series and not applied but remaining unclaimed by the holders of such Securities for two years after the date upon which the principal of (or premium, if any) or interest on such Securities, as the case may be, shall have become due and payable, shall on written request of the Corporation be repaid to the Corporation by the Trustee; and the holder of any of such Securities shall thereafter look only to the Corporation for any payment which such holder may be entitled to collect. Any reference to the Trustee in this Section 13.04 shall be deemed to also include any entity designated by the Corporation with the consent of the Trustee to act as its agent for the performance of all or any of its duties under this Section.

ARTICLE 14

ARTICLE 15
SINKING FUNDS

        Section 15.01.    General.    Any redemption of Securities of any series under any sinking fund as required or permitted by the terms of any Securities duly issued pursuant to this Indenture shall be made in accordance with such terms and this Article 15.

        The Securities of any series may be subject to redemption pursuant to a sinking fund, in whole or in part, as set forth in the form of Security for such series.

        The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a "mandatory sinking fund payment," and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an "optional sinking fund payment." If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 15.02 hereof. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series.

        Section 15.02.    Satisfaction of Sinking Fund Payments with Securities.    The Corporation (a) may deliver to the Trustee for cancellation outstanding Securities of a series (other than any previously called for redemption) and (b) may apply as a credit Securities of a series which have been redeemed either at the election of the Corporation pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series required to be made pursuant to the terms of such Securities as provided for by the terms of such series; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the redemption price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.

42

---

        Section 15.03.    Redemption of Securities for Sinking Fund.    Not less than sixty days prior to each sinking fund payment date for any series of Securities, the Corporation will deliver to the Trustee an Officers' Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities of that series as permitted by Section 15.02 and will also deliver to the Trustee any Securities to be so delivered if not theretofore delivered. The Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 4.03 and cause notice of the redemption thereof to be given in the manner provided in Section 4.04. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 4.05 and 4.06.

ARTICLE 16
CONVERSION OF SECURITIES

        Section 16.01.    Conversion Privilege and Conversion Rate.    Subject to and upon compliance with the provisions of this Article, at the option of the Securityholder thereof, any Convertible Security may be converted into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock at the Conversion Rate, determined as hereinafter provided, in effect at the time of conversion. Such conversion right shall commence for each series of Convertible Securities at the opening of business on and expire at the close of business on the dates set forth in or pursuant to the Board Resolution establishing the terms of that series, and specified in an Officers' Certificate if not so specified in a Board Resolution, subject, in the case of any Convertible Security issued in global form, to any Applicable Procedures. In case a Convertible Security or portion thereof is called for redemption, such conversion right in respect of the Convertible Security, or portion thereof so called, shall expire at the close of business on the Business Day immediately preceding the Redemption Date for Convertible Securities of that series, unless the Corporation defaults in making the payment due upon redemption (subject as aforesaid to any Applicable Procedures with respect to Convertible Security issued in global form).

        Convertible Securities of any series may be converted initially at a conversion rate (the "Conversion Rate") set forth in or pursuant to the Board Resolution establishing the terms of that series and specified in an Officers' Certificate if not so specified in a Board Resolution. The Conversion Rate for each outstanding series will be adjusted in certain instances as provided in Section 16.04.

        Section 16.02.    Exercise of Conversion Privilege.    In order to exercise the conversion privilege, the Securityholder of any Convertible Security to be converted shall surrender such Convertible Security, duly endorsed in blank, at any office or agency of the Corporation maintained for that purpose pursuant to Section 5.02 of this Indenture, accompanied by a duly signed conversion notice substantially in the form established by or pursuant to the Board Resolution establishing the terms of such series stating that the Securityholder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted. Each Convertible Security surrendered for conversion (in whole or in part) during the Record Date Period (except in the case of any Convertible Security or portion thereof which has been called for redemption on a Redemption Date occurring within such Record Date Period and, as a result, the right to convert such Convertible Security would otherwise terminate in such period if not exercised) be accompanied by payment in New York Clearing House funds or other funds acceptable to the Corporation of an amount equal to the interest payable on such interest payment date on the initial principal amount of such Convertible Security (or part thereof, as the case may be) being surrendered for conversion. The interest so payable on such interest payment date with respect to any Convertible Security (or portion thereof, if applicable) that is surrendered for conversion during the Record Date Period shall be paid to the

43

---

Securityholder of such Convertible Security as of such regular record date in an amount equal to the interest that would have been payable on such Convertible Security if such Convertible Security had been converted as of the close of business on such interest payment date. Interest payable on any interest payment date in respect of any Convertible Security surrendered for conversion on or after such interest payment date shall be paid to the Securityholder of such Convertible Security as of the regular record date next preceding such interest payment date, notwithstanding the exercise of the right of conversion. Except as provided in this paragraph, no cash payment or adjustment shall be made upon any conversion on account of any interest accrued from the interest payment date next preceding the conversion date, in respect of any Convertible Security (or part thereof, as the case may be) surrendered for conversion, or on account of any dividends on the securities issued upon conversion. The Corporation's delivery to the Securityholder of the number of shares of Common Stock (and cash in lieu of fractions thereof, as provided in this Indenture) into which a Convertible Security is convertible will be deemed to satisfy the Corporation's obligation to pay the principal amount of the Convertible Security.

        Convertible Securities shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Convertible Securities for conversion in accordance with the foregoing provisions, and at such time the rights of the Securityholders of such Convertible Securities as Securityholders shall cease, and the person or persons entitled to receive the shares of Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such securities at such time. As promptly as practicable on or after the conversion date, the Corporation shall issue and deliver to the Trustee, for delivery to the Securityholder (unless a different person is indicated on the Conversion Notice), a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any fraction of a share, as provided in Section 16.03.

        In the case of any Convertible Security which is converted in part only, upon such conversion the Corporation shall execute and the Trustee shall authenticate and deliver to the Securityholder thereof, at the expense of the Corporation, a new Convertible Security or Securities of authorized denominations in an aggregate principal amount equal to the unconverted portion of the principal amount of such Security. A Security may be converted in part, but only if the principal amount of such Security to be converted is any integral multiple of U.S. $1,000 and the principal amount of such security to remain Outstanding after such conversion is equal to U.S. $1,000 or any integral multiple of $1,000 in excess thereof.

        Section 16.03.    Fractions of Shares.    No fractional shares of Common Stock shall be issued upon conversion of any Convertible Security or Securities. If more than one Convertible Security shall be surrendered for conversion at one time by the same Securityholder, the number of full shares which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Convertible Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be issuable upon conversion of any Convertible Security or Securities (or specified portions thereof), the Corporation shall calculate and pay a cash adjustment in respect of such fraction (calculated to the nearest 1/100th of a share) in an amount equal to the same fraction of the Closing Price Per Share at the close of business on the day of conversion.

        Section 16.04.    Adjustment of Conversion Rate.    The Conversion Rate shall be subject to adjustments from time to time as follows:

        (a)   In case the Corporation shall pay or make a dividend or other distribution on shares of any class of capital stock payable in shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the date fixed for the determination of shareholders

44

---

entitled to receive such dividend or other distribution shall be increased by dividing the Conversion Rate in effect immediately prior to such date by a fraction:

          (i)  the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and

         (ii)  the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution.

        Such increase will become effective immediately after the opening of business on the day following the date fixed for such determination. If, after any such date fixed for determination, any dividend or distribution is not in fact paid, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would have been in effect if such determination date had not been fixed. For the purposes of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Corporation but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Corporation will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Corporation.

        (b)   Subject to the last sentence of paragraph (g) of this Section 16.04, in case the Corporation shall issue rights, options or warrants to all holders of its Common Stock entitling them to subscribe for or purchase shares of Common Stock at a price per share less than the current market price per share (determined as provided in paragraph (h) of this Section 16.04) of the Common Stock on the date fixed for the determination of stockholders entitled to receive such rights, options or warrants (other than any rights, options or warrants that by their terms will also be issued to any Securityholder upon conversion of a Convertible Security into shares of Common Stock without any action required by the Corporation or any other person), the Conversion Rate in effect at the opening of business on the day following the date fixed for such determination shall be increased by dividing the Conversion Rate in effect immediately prior to such date by a fraction:

          (i)  the numerator of which will be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock that the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such current market price and

         (ii)  the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase.

        Such increase will become effective immediately after the opening of business on the day following the date fixed for such determination. If, after any such date fixed for determination, any such rights, options or warrants are not in fact issued, or are not exercised prior to the expiration thereof, the Conversion Rate shall be immediately readjusted, effective as of the date such rights, options or warrants expire, or the date the Board of Directors determines not to issue such rights, options or warrants, to the Conversion Rate that would have been in effect if the unexercised rights, options or warrants had never been granted or such determination date had not been fixed, as the case may be. For the purposes of this paragraph (b), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Corporation but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Corporation will not issue any rights, options or warrants in respect of shares of Common Stock held in the treasury of the Corporation.

45

---

        (c)   In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and, conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

        (d)   Subject to the last sentence of paragraph (g) of this Section 16.04, in case the Corporation shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness, shares of any class of capital stock or rights, options or warrants to subscribe for or purchase shares of any class of capital stock (other than any rights, options or warrants that by their terms will also be issued to any Securityholder upon conversion of a Convertible Security into shares of Common Stock without any action required by the Corporation or any other person) or other property (including cash or assets or securities, but excluding (i) any rights, options or warrants referred to in paragraph (b) of this Section, (ii) any dividend or distribution paid exclusively in cash, other than those referred to in paragraphs (e) and (f) below, (iii) any dividend or distribution referred to in paragraph (a) of this Section and (iv) any consideration distributed in any merger or consolidation to which Section 16.11 applies), the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect immediately prior to the close of business on the date fixed for the determination of stockholders entitled to receive such distribution by a fraction:

          (i)  the numerator of which will be the current market price per share (determined as provided in paragraph (h) of this Section 16.04) of the Common Stock on the date fixed for such determination less the then fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution filed with the Trustee) of the portion of the assets, shares or evidences of indebtedness so distributed applicable to one share of Common Stock and

         (ii)  the denominator shall be such current market price per share of the Common Stock.

        Such adjustment will become effective immediately prior to the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such distribution. If after any such date fixed for determination, any such distribution is not in fact made, the Conversion Rate shall be immediately readjusted, effective as of the date that the Board of Directors determines not to make such distribution, to the Conversion Rate that would have been in effect if such determination date had not been fixed.

        (e)   In case the Corporation shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding cash distributed upon a merger or consolidation to which Section 16.11 applies) in an aggregate amount that, combined together with (i) the aggregate amount of any other all-cash distributions to all holders of its Common Stock made exclusively in cash within the 365-day period preceding the date of payment of such distribution and in respect of which no adjustment pursuant to this paragraph (e) or paragraph (f) of this Section 16.04 has been made and (ii) the aggregate of any cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) of any non-cash consideration payable in respect of any tender offer by the Corporation or any of its Subsidiaries for all or any portion of the Common Stock concluded within the 365-day period preceding the date of payment of such distribution and in respect of which no adjustment pursuant to paragraph (f) of this Section 16.04 has been made (the "combined cash and tender amount")

46

exceeds 10% of the product of the current market price per share (determined as provided in paragraph (h) of this Section 16.04) of the Common Stock on the date for the determination of holders of shares of Common Stock entitled to receive such distribution times the number of shares of Common Stock outstanding on such date (the "aggregate current market price"), then, and in each such case, immediately after the close of business on such date for determination, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect immediately prior to the close of business on the date fixed for determination of the stockholders entitled to receive such distribution by a fraction:

          (i)  the numerator of which shall be equal to the current market price per share (determined as provided in paragraph (h) of this Section 16.04) of the Common Stock on the date fixed for such determination less an amount equal to the quotient of (x) the excess of such combined cash and tender amount over 10% of such aggregate current market price divided by (y) the number of shares of Common Stock outstanding on such date for determination and

         (ii)  the denominator of which shall be equal to the current market price per share (determined as provided in paragraph (h) of this Section 16.04) of the Common Stock on such date fixed for determination.

        (f)    In case a tender offer made by the Corporation or any Subsidiary for all or any portion of the Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender offer) of Purchased Shares (as defined below)) of an aggregate consideration having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) that combined together with (i) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution), as of the expiration of such tender offer, of any non-cash consideration payable in respect of any other tender offer by the Corporation or any Subsidiary for all or any portion of the Common Stock expiring within the 365-day period preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this paragraph (f) or paragraph (e) of this Section 16.04 has been made and (ii) the aggregate amount of any cash distributions to all holders of the Common Stock within 365-day period preceding the expiration of such tender offer and in respect of which no adjustment pursuant to paragraph (e) of this Section 16.04 has been made (the "combined tender and cash amount") exceeds 10% of the product of the current market price per share of the Common Stock (determined as provided in paragraph (h) of this Section 16.04) as of the last time (the "Expiration Time") tenders could have been made pursuant to such tender offer (as it may be amended) times the number of shares of Common Stock outstanding (including any tendered shares) as of the Expiration Time, then, and in each such case immediately prior to the opening of business on the day after the date of the Expiration Time, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate immediately prior to the close of business on the date of the Expiration Time by a fraction

          (i)  the numerator of which shall be equal to (A) the product of (1) the current market price per share of the Common Stock (determined as provided in paragraph (h) of this Section 16.04) on the date of the Expiration Time multiplied by (2) the number of shares of Common Stock outstanding (including any tendered shares) on the date of the Expiration Time less (B) the combined tender and cash amount, and

         (ii)  the denominator of which shall be equal to the product of (A) the current market price per share of the Common Stock (determined as provided in paragraph (h) of this Section 16.04) on the date of the Expiration Time multiplied by (B) the number of shares of

47

---

Common Stock outstanding (including any tendered shares) as of the Expiration Time less the number of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted up to any such maximum, being referred to as the "Purchased Shares").

        (g)   The reclassification of Common Stock into securities other than Common Stock (other than any reclassification upon a consolidation or merger to which Section 16.11 applies) shall be deemed to involve (i) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be "the date fixed for the determination of stockholders entitled to receive such distribution" and "the date fixed for such determination" within the meaning of paragraph (d) of this Section 16.04), and (ii) a subdivision or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be "the day upon which such subdivision becomes effective" or "the day upon which such combination becomes effective," as the case may be, and "the day upon which such subdivision or combination becomes effective" within the meaning of paragraph (c) of this Section 16.04). Rights, options or warrants issued by the Corporation to all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of capital stock of the Corporation, which rights, options or warrants (i) are deemed to be transferred with such shares of Common Stock, (ii) are not exercisable and (iii) are also issued in respect of future issuances of shares of capital stock, in each case in clauses (i) through (iii) until the occurrence of a specified event or events ("Trigger Event"), shall for purposes of this Section 16.04 not be deemed issued or distributed until the occurrence of the earliest Trigger Event.

        (h)   For the purpose of any computation under paragraphs (b), (d), (e) or (f) of this Section 16.04, the current market price per share of Common Stock on any date shall be calculated by the Corporation and be the average of the daily Closing Prices Per Share for the five consecutive Trading Days selected by the Corporation commencing not more than 10 Trading Days before, and ending not later than the earlier of the day in question and the day before the "ex date" with respect to the issuance or distribution requiring such computation. For purposes of this paragraph, the term "ex date," when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way in the applicable securities market or on the applicable securities exchange without the right to receive such issuance or distribution.

        (i)    No adjustment in the Conversion Rate shall be required unless such adjustment (plus any adjustments not previously made by reason of this paragraph (i)) would require an increase or decrease of at least one percent in such rate; provided, however, that any adjustments which by reason of this paragraph (i) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be.

        (j)    The Corporation may make such increases in the Conversion Rate, for the remaining term of the Securities or any shorter term, in addition to those required by paragraphs (a), (b), (c), (d), (e) and (f) of this Section 16.04, as it considers to be advisable in order to avoid or diminish any income tax to any holders of shares of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes. The Corporation shall have the power to resolve any ambiguity or correct any error in this paragraph (j) and its actions in so doing shall, absent manifest error, be final and conclusive.

        (k)   Notwithstanding the foregoing provisions of this Section, no adjustment of the Conversion Rate shall be required to be made (i) upon the issuance of shares of Common Stock pursuant to any present or future plan for the reinvestment of dividends, (ii) upon a change in the par value of

48

the Common Stock or (iii) because of a tender or exchange offer of the character described in Rule 13e-4(h)(5) under the Securities Exchange Act of 1934, as amended, or any successor rule thereto.

        (l)    To the extent permitted by applicable law, the Corporation from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least 20 days, the increase is irrevocable during such period, and the Board of Directors shall have made a determination that such increase would be in the best interests of the Corporation, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Corporation shall give notice of the increase to the Securityholders in the manner provided in Section 17.03 hereof at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

        Section 16.05.    Notice of Adjustments of Conversion Rate.    Whenever the Conversion Rate is adjusted as herein provided:

        (a)   the Corporation shall compute the adjusted Conversion Rate in accordance with Section 16.04 hereof and shall prepare a certificate signed by the Chief Financial Officer or Treasurer of the Corporation setting forth the adjusted Conversion Rate and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall promptly be filed with the Trustee and with each Conversion Agent; and

        (b)   upon each such adjustment, a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate shall be required, and as soon as practicable after it is required, such notice shall be provided by the Corporation to all Securityholders of Convertible Securities in accordance with Section 17.03.

        Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate or the information and calculations contained therein, except to exhibit the same to any holder of Securities desiring inspection thereof at its office during normal business hours, and shall not be deemed to have knowledge of any adjustment in the Conversion Rate unless and until a Responsible Officer of the Trustee shall have received such a certificate. Until a Responsible Officer of the Trustee receives such a certificate, the Trustee and each Conversion Agent may assume without inquiry that the last Conversion Rate of which the Trustee has knowledge remains in effect.

        Section 16.06.    Notice of Certain Corporate Action.    In case:

        (a)   the Corporation shall declare a dividend (or any other distribution) on its Common Stock payable (i) otherwise than exclusively in cash or (ii) exclusively in cash in an amount that would require any adjustment pursuant to Section 16.04; or

        (b)   the Corporation shall authorize the granting to all or substantially all of the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights; or

        (c)   of any reclassification of the Common Stock, or of any consolidation, merger or share exchange to which the Corporation is a party and for which approval of any stockholders of the Corporation is required, or of the conveyance, sale, transfer or lease of all or substantially all of the assets of the Corporation; or

        (d)   of the voluntary or involuntary dissolution, liquidation or winding up of the Corporation; then the Corporation shall cause to be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 5.02 of this Indenture, and shall cause to be provided to all Securityholders in accordance with Section 17.03 hereof, at least 20 days (or 10 days in any

case specified in clause (a) or (b) above) prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights, options or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, conveyance, transfer, sale, lease, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, conveyance, transfer, sale, lease, dissolution, liquidation or winding up. Neither the failure to give such notice or the notice referred to in the following paragraph nor any defect therein shall affect the legality or validity of the proceedings described in clauses (a) through (d) of this Section 16.06. If at the time the Trustee shall not be the Conversion Agent, a copy of such notice shall also forthwith be filed by the Corporation with the Trustee.

        The Corporation shall cause to be filed at the principal office of the Trustee and each office or agency maintained for the purpose of conversion of Convertible Securities pursuant to Section 5.02 of this Indenture, and shall cause to be provided to all Securityholders in accordance with Section 17.03 hereof, notice of any tender offer by the Corporation or any Subsidiary for all or any portion of the Common Stock at or about the time that such notice of tender offer is provided to the public generally.

        Section 16.07.    Corporation to Reserve Common Stock; Registration; Listing.    (a) The Corporation shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Convertible Securities, the full number of shares of Common Stock then issuable upon the conversion of all Outstanding Convertible Securities.

        (b)   The Corporation covenants that so long as the Common Stock shall be listed on the New York Stock Exchange, the Corporation will, if permitted by the rules of such exchange, list and keep listed all Common Stock issuable upon conversion of the Convertible Securities, and the Corporation will endeavor to list the shares of Common Stock required to be delivered upon conversion of the Convertible Securities prior to such delivery upon any other national securities exchange upon which the outstanding Common Stock is listed at the time of such delivery.

        Section 16.08.    Taxes on Conversions.    Except as provided in the next sentence, the Corporation will pay all stamp taxes and other duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Convertible Securities pursuant hereto. The Corporation shall not, however, be required to pay any tax or duty that may be payable in respect of (a) income of the Securityholder, or (b) any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Securityholder of the Convertible Security or Securities to be converted, and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Corporation the amount of any such tax or duty, or has established to the satisfaction of the Corporation that such tax or duty has been paid.

        Section 16.09.    Covenant as to Common Stock.    The Corporation agrees that all shares of Common Stock that may be delivered upon conversion of Convertible Securities, upon such delivery, will have been duly authorized and validly issued and will be fully paid and nonassessable and, except as provided in Section 16.08 hereof, the Corporation will pay all taxes, liens and charges with respect to the issue thereof.

        Section 16.10.    Cancellation of Converted Securities.    All Convertible Securities delivered for conversion shall be delivered to the Trustee or its agent to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 3.07 of this Indenture.

        Section 16.11.    Provision in Case of Consolidation, Merger Or Sale Of Assets.    In case of any consolidation or merger of the Corporation with or into any other person or any merger of another person with or into the Corporation (other than a merger that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock) or any conveyance, sale, transfer or lease of all or substantially all of the assets of the Corporation (other than a sale of all or substantially all of the assets of the Corporation that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock), the person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Securityholder of each Convertible Security then Outstanding shall have the right thereafter, during the period such Convertible Security shall be convertible as specified in Section 16.01 hereof, to convert such Convertible Security only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease by a holder of the number of shares of Common Stock into which such Convertible Security might have been converted immediately prior to such consolidation, merger, conveyance, sale, transfer or lease, assuming such holder of Common Stock (a) is not (i) a person with which the Corporation consolidated or merged with or into or which merged into or with the Corporation or to which such conveyance, sale, transfer or lease was made, as the case may be (a "Constituent Person"), or (ii) an Affiliate of a Constituent Person and (b) failed to exercise his rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease (provided that if the kind or amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer, or lease is not the same for each share of Common Stock held immediately prior to such consolidation, merger, conveyance, sale, transfer or lease by others than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised ("Non-electing Share"), then for the purpose of this Section 16.11 the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease by the holders of each Non-electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-electing Shares). Such supplemental indenture shall provide for adjustments that, for events subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article. The above provisions of this Section 16.11 shall similarly apply to successive consolidations, mergers, conveyances, sales, transfers or leases.

        Notice of the execution of such a supplemental indenture shall be given by the Corporation to the Securityholder of each Convertible Security as provided in Section 17.03 hereof promptly upon such execution.

        Neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any such supplemental indenture relating either to the kind or amount of shares of stock or other securities or property or cash receivable by Securityholders upon the conversion of their Convertible Securities after any such consolidation, merger, conveyance, transfer, sale or lease or to any such adjustment, but may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an Officers' Certificate or an Opinion of Counsel with respect thereto, which the Corporation shall cause to be furnished to the Trustee upon request.

        Section 16.12.    Responsibility of Trustee for Conversion Provisions.    The Trustee, subject to the provisions of Section 8.01 hereof, and any Conversion Agent shall not at any time be under any duty or responsibility to any Securityholder to determine whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed, herein or in any supplemental indenture provided to be employed, in making the same, or whether a supplemental indenture need be entered into.

        The Notes are issuable only as registered Notes without coupons in denominations of $1,000 or any amount in excess thereof that is an integral multiple of $1,000. As provided in the Indenture, and subject to certain limitations herein and therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes of other authorized denominations having the same interest rate, Stated Maturity, optional redemption or repurchase provisions, if any, and Original Issue Date, as requested by the Securityholder surrendering the same.

        No service charge will be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

        The Company, the Trustee, the Bank, the Security registrar and any agent of the Company, the Trustee, the Bank, or the Security registrar may treat the Securityholder in whose name this Note is registered as the absolute owner hereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Note is overdue, and neither the Company, the Trustee, the Bank, the Security registrar nor any such agent shall be affected by notice to the contrary.

        If an Event of Default (as defined in the Indenture) with respect to the Notes shall occur and be continuing, the principal of all the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

        The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the holders of the Securities of any series under the Indenture at any time by the Company with the consent of the holders of not less than 66²/3% in aggregate principal amount of the Securities at the time Outstanding to be affected (voting as one class). The Indenture also permits the Company and the Trustee to enter into supplemental indentures without the consent of the holders of Securities of any series for certain purposes specified in the Indenture, including the making of such other provisions in regard to matters arising under the Indenture which shall not adversely affect the interest of the holders of such Securities. The Indenture also contains provisions permitting the holders of specified percentages in aggregate principal amount of the Securities of any series at the time Outstanding, on behalf of the holders of all the Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note.

        The Indenture provides that no holder of any Security of any series may enforce any remedy with respect to such series under the Indenture except in the case of refusal or neglect of the Trustee to act after notice of a continuing Event of Default and after written request by the holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such series and the offer to the Trustee of reasonable indemnity; provided, however, that such provision shall not prevent the holder hereof from enforcing payment of the principal of or interest on this Note.

SERIES                        , due

(FLOATING RATE NOTE)

        This Note is one of a duly authorized issue of debt securities (the "Securities") of the Company, of a series designated as its Series                        , due                                    (herein called the "Notes"), limited (except as otherwise provided in the Indenture) in aggregate principal amount to $                                    , issued and to be issued under the Indenture, to which Indenture and all relevant indentures supplemental thereto reference is hereby made for a statement of the respective rights, obligations, duties and immunities thereunder of the Company, the Trustee, the Bank and the Securityholder and the terms upon which the Notes are, and are to be, authenticated and delivered. The Securities, of which the Notes constitute a series, may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest at different rates, may be subject to different covenants and Events of Default and may otherwise vary as in the Indenture provided. All capitalized terms not otherwise defined herein shall have the definitions assigned to them in the Indenture.

        Commencing with the applicable Interest Reset Date first following the Original Issue Date specified on the face hereof, the rate at which interest on this Note is payable shall be reset daily, weekly, monthly, quarterly, semi-annually or annually as shown on the face hereof. The interest rate per annum for each interest reset period shall be calculated on the applicable Interest Determination Date specified on the face hereof and shall be the Interest Rate Basis specified on the face hereof, determined in accordance with the provisions of the applicable heading below, adjusted by adding or subtracting a Spread and/or multiplying by a Spread Multiplier, as the case may be, specified on the face hereof; provided, however, that (i) the interest rate in effect from the Original Issue Date to the first Interest Reset Date with respect to this Note will be the Initial Interest Rate specified on the face hereof and (ii) the interest rate in effect for the ten days immediately prior to the Stated Maturity or redemption or repurchase will be that in effect on the tenth day preceding such Stated Maturity or redemption or repurchase. Each such adjusted rate shall be applicable on and after the Interest Reset Date to which it relates, to, but not including, the next succeeding Interest Reset Date or until the Stated Maturity, or the date of redemption or repurchase, as the case may be. If any Interest Reset Date would otherwise be a day that is not a Business Day, such Interest Reset Date shall be postponed to the next succeeding day that is a Business Day (as defined below), except that if the Interest Rate Basis specified on the face hereof is LIBOR, and if such Business Day is in the next succeeding calendar month, such Interest Reset Date shall be the immediately preceding Business Day. Subject to provisions of applicable law and except as specified herein, on each Interest Reset Date the rate of interest on this Note shall be the rate determined in accordance with the provisions of the applicable heading below.

        All percentages resulting from any calculation on this Note will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts used in or resulting from such calculation will be rounded to the nearest cent with one-half cent being rounded upward.

DETERMINATION OF CD RATE.

        If the Interest Rate Basis on this Note is the CD Rate, the CD Rate with respect to this Note shall equal the rate on each Interest Determination Date designated on the face hereof for negotiable certificates of deposit having the Index Maturity designated on the face hereof as published in

B-5

---

H.15(519) under the heading "CDs (Secondary Market)." In the event that such rate is not published prior to 9:00 A.M., New York City time, on the Calculation Date designated on the face hereof pertaining to such Interest Determination Date, then the CD Rate will be the rate on such Interest Determination Date for negotiable certificates of deposit having the Index Maturity as published in Composite Quotations under the heading "Certificates of Deposit." If such rate was neither published in H.15(519) by 9:00 A.M., New York City time, on such Calculation Date nor in Composite Quotations by 3:00 P.M., New York City time, on such date, the CD Rate for that CD Interest Determination Date shall be calculated by the Calculation Agent and shall be the arithmetic mean of the secondary market offered rates, as of 10:00 A.M., New York City time, on that Interest Determination Date, of three leading nonbank dealers of negotiable U.S. dollar certificates of deposit in The City of New York selected by the Calculation Agent for negotiable certificates of deposit of major United States money market banks with a remaining maturity closest to the Index Maturity in a denomination of $5,000,000; provided, however, that if fewer than three dealers selected as aforesaid by the Calculation Agent are quoting as mentioned in this sentence, the rate of interest in effect for the applicable period will be the same as the CD Rate as adjusted for the Spread and/or Spread Multiplier, as the case may be, for the immediately preceding interest reset period.

        The CD Rate determined with respect to any Interest Determination Date will become effective on and as of the applicable Interest Reset Date specified on the face hereof; provided, however, that (i) the interest rate in effect for the period from the Original Issue Date to first Interest Reset Date will be the Initial Interest Rate specified on the face hereof, and (ii) the interest rate in effect for the ten days immediately preceding the Stated Maturity or redemption will be that in effect on the tenth day preceding such Stated Maturity or redemption.

DETERMINATION OF COMMERCIAL PAPER RATE.

        If the Interest Rate Basis on this Note is the Commercial Paper Rate, the Commercial Paper Rate with respect to this Note shall equal the Money Market Yield (calculated as described below) of the rate on each Interest Determination Date designated on the face hereof for commercial paper having the Index Maturity designated on the face hereof as published in H.15(519) under the heading "Commercial Paper." In the event that such rate is not published prior to 9:00 A.M., New York City time, on the Calculation Date designated on the face hereof pertaining to such Interest Determination Date, then the Commercial Paper Rate will be the Money Market Yield of the rate on such Interest Determination Date for commercial paper having the Index Maturity as published in Composite Quotations under the heading "Commercial Paper." If such rate was neither published in H.15(519) by 9:00 A.M., New York City time, on such Calculation Date nor in Composite Quotations by 3:00 P.M., New York City time, on such date, the Commercial Paper Rate for that Interest Determination Date will be calculated by the Calculation Agent and will be the Money Market Yield of the arithmetic mean of the offered rates, as of 11:00 A.M., New York City time, on that Interest Determination Date, of three leading dealers of commercial paper in The City of New York selected by the Calculation Agent for commercial paper having the Index Maturity designated on the face hereof placed for an industrial issuer whose bond rating is "AA," or the equivalent, from a nationally recognized rating agency; provided, however, that if fewer than three dealers selected as aforesaid by the Calculation Agent are quoting as mentioned in this sentence, the rate of interest in effect for the applicable period will be the same as the Commercial Paper Rate as adjusted for the Spread and/or Spread Multiplier, as the case may be, for the immediately preceding interest reset period.

        "Money Market Yield" shall be a yield (expressed as a percentage rounded upwards, if necessary, to the next higher one-hundred thousandth of a percentage point) calculated in accordance with the following formula:

B-6

---

where "D" refers to the per annum rate for commercial paper quoted on a bank discount basis and expressed as a decimal; and "M" refers to the actual number of days in the period for which interest is being calculated.

        The Commercial Paper Rate determined with respect to any Interest Determination Date will become effective on and as of the applicable Interest Reset Date specified on the face hereof; provided, however, that (i) the interest rate in effect for the period from the Original Issue Date to the first Interest Reset Date will be the Initial Interest Rate specified on the face hereof; and (ii) the interest rate in effect for the ten days immediately preceding the Stated Maturity or redemption will be that in effect on the tenth day preceding such Stated Maturity or redemption.

DETERMINATION OF LIBOR.

        If the Interest Rate Basis on this Note is LIBOR, LIBOR with respect to this Note will be determined by the Calculation Agent in accordance with the following provisions:

        (a)   With respect to any Interest Determination Date, LIBOR will be determined by either (i) the arithmetic mean of the offered rates for deposits in U.S. dollars having the Index Maturity designated on the face hereof, commencing on the second Business Day immediately following such Interest Determination Date, which appear on the Reuters Screen LIBO Page as of 11:00 A.M., London time, on that Interest Determination Date, if at least two such offered rates appear on the Reuters Screen LIBO Page, or (ii) the rate for deposits in U.S. dollars having the Index Maturity designated on the face hereof, commencing on the second Business Day immediately following such Interest Determination Date, that appears on the Telerate Page 3750 as of 11:00 a.m., London time, on such Interest Determination Date. If neither Reuters Screen LIBO Page nor Telerate Page 3750 is specified on the face hereof, LIBOR will be determined as if Telerate Page 3750 had been specified.

        (b)   With respect to an Interest Determination Date on which fewer than two offered rates appear on the Reuters Screen LIBO Page or no rate appears on Telerate Page 3750 for the applicable Index Maturity as described in (a) above, LIBOR will be determined on the basis of the rates at approximately 11:00 A.M., London time, on such Interest Determination Date at which deposits in U.S. dollars having the Index Maturity designated on the face hereof are offered to prime banks in the London interbank market by four major banks in the London interbank market selected by the Calculation Agent commencing on the second Business Day immediately following such Interest Determination Date and in a principal amount not less than $1,000,000 that in the Calculation Agent's judgment is representative for a single transaction in such market at such time (a "Representative Amount"). The Calculation Agent will request the principal London office of each of such banks to provide a quotation of its rate. If at least two such quotations are provided, LIBOR for such Interest Determination Date will be the arithmetic mean of such quotations. If fewer than two quotations are provided, LIBOR for such Interest Determination Date will be the arithmetic mean of the rates quoted at approximately 11:00 A.M., New York City time, on such Interest Determination Date by three major banks in The City of New York, selected by the Calculation Agent, for loans in U.S. dollars to leading European banks having the specified Index Maturity commencing on the second Business Day immediately following such Interest Determination Date and in a Representative Amount; provided, however, that if fewer than three banks selected as aforesaid by the Calculation Agent are quoting as mentioned in this sentence, the rate of interest in effect for the applicable period will be the same as LIBOR as adjusted for the Spread and/or Spread Multiplier, as the case may be, for the immediately preceding interest reset period.

        LIBOR determined with respect to any Interest Determination Date will become effective on and as of the applicable Interest Reset Date specified on the face hereof; provided, however, that (i) the

B-7

---

interest rate in effect for the period from the Original Issue Date to the first Interest Reset Date will be the Initial Interest Rate specified on the face hereof and (ii) the interest rate in effect for the ten days immediately preceding the Stated Maturity or redemption will be that in effect on the tenth day preceding such Stated Maturity or redemption.

DETERMINATION OF FEDERAL FUNDS EFFECTIVE RATE.

        If the Interest Rate Basis on this Note is the Federal Funds Effective Rate, the Federal Funds Effective Rate with respect to this Note shall equal with respect to each Interest Determination Date designated on the face hereof the rate on such date for Federal Funds as published in H.15(519) under the heading "Federal Funds (Effective)" or, if not so published prior to 11:00 A.M., New York City time, on the Calculation Date designated on the face hereof pertaining to such Interest Determination Date, then the Federal Funds Effective Rate will be the rate on such Interest Determination Date as published in Composite Quotations under the heading "Federal Funds/Effective Rate." If such rate was neither published in H.15(519) by 11:00 A.M., New York City time, on such Calculation Date nor in Composite Quotations by 3:00 P.M., New York City time, on such date, the Federal Funds Effective Rate for such Interest Determination Date will be calculated by the Calculation Agent and will be the arithmetic mean of the rates, as of 11:00 A.M., New York City time, on that Interest Determination Date, for the last transaction in overnight Federal Funds arranged by three leading brokers of Federal Funds transactions in The City of New York selected by the Calculation Agent; provided, however, that if fewer than three brokers selected as aforesaid by the Calculation Agent are quoting as mentioned in this sentence, the rate of interest in effect for the applicable period will be the same as the Federal Funds Effective Rate as adjusted for the Spread and/or Spread Multiplier, as the case may be, for the immediately preceding interest reset period.

        The Federal Funds Effective Rate determined with respect to any Interest Determination Date will become effective on and as of the applicable Interest Reset Date specified on the face hereof; provided, however, that (i) the interest rate in effect for the period from the Original Issue Date to the first Interest Reset Date will be the Initial Interest Rate specified on the face hereof; and (ii) the interest rate in effect for the ten days immediately preceding the Stated Maturity or redemption will be that in effect on the tenth day preceding such Stated Maturity or redemption.

DETERMINATION OF PRIME RATE.

        If the Interest Rate Basis on this Note is the Prime Rate, the Prime Rate with respect to the Note shall equal with respect to each Interest Determination Date designated on the face hereof the rate set forth on such date in H.15(519) under the heading "Bank Prime Loan." In the event that such rate is not published prior to 9:00 A.M., New York City time, on the Calculation Date designated on the face hereof pertaining to such Interest Determination Date, then the Prime Rate will be the arithmetic mean (rounded upwards, if necessary, to the next higher one-hundred thousandth of a percentage point) of the rates of interest publicly announced by each bank that appear on the Reuters Screen USPRIMEONE Page as such bank's prime rate or base lending rate as in effect for that Interest Determination Date. If fewer than four such rates but more than one such rate appear on the Reuters Screen USPRIMEONE Page for the Interest Determination Date, the Prime Rate will be the arithmetic mean of the prime rates (quoted on the basis of the actual number of days in the year divided by a 360-day year) as of the close of business on such Interest Determination Date by four major money center banks in The City of New York selected by the Calculation Agent. If fewer than two quotations are provided, the Prime Rate shall be determined on the basis of the rates furnished in The City of New York by the appropriate number of substitute banks or trust companies organized and doing business under the laws of the United States, or any State thereof, having total equity capital of at least $500 million and being subject to supervision or examination by a Federal or State authority, selected by the Calculation Agent to provide such rate or rates; provided, however, that if the banks

B-8

---

selected as aforesaid by the Calculation Agent are not quoting as mentioned in this sentence, the rate of interest in effect for the applicable period will be the same as the Prime Rate as adjusted for the Spread and/or Spread Multiplier, as the case may be, for the immediately preceding interest reset period.

        The Prime Rate determined with respect to any Interest Determination Date will become effective on and as of the applicable Interest Reset Date specified on the face hereof; provided, however, that (i) the interest rate in effect for the period from the Original Issue Date to the first Interest Reset Date will be the Initial Interest Rate specified on the face hereof; and (ii) the interest rate in effect for the ten days immediately preceding the Stated Maturity or redemption will be that in effect on the tenth day preceding such Stated Maturity or redemption.

DETERMINATION OF TREASURY RATE.

        If the Interest Rate Basis on this Note is the Treasury Rate, the Treasury Rate with respect to this Note shall equal with respect to each Interest Determination Date designated on the face hereof the rate for the most recent auction of direct obligations of the United States ("Treasury bills") having the Index Maturity designated on the face hereof as published in H.15(519) under the heading, "U.S. Government Securities/Treasury Bills/Auction Average (Investment)" or, if not so published by 9:00 A.M., New York City time, on the Calculation Date designated on the face hereof pertaining to such Interest Determination Date, the auction average rate (expressed as a bond equivalent, on the basis of a year of 365 or 366 days, as applicable, and applied on a daily basis) for such auction as otherwise announced by the United States Department of the Treasury. In the event that the results of the auction of Treasury bills having the Index Maturity designated on the face hereof are neither published in H.15(519) by 9:00 A.M., New York City time, on such Calculation Date, nor otherwise published or reported as provided above by 3:00 P.M., New York City time on such date, or if no such auction is held in a particular week, then the Treasury Rate shall be calculated by the Calculation Agent and shall be a yield to maturity (expressed as a bond equivalent, on the basis of a year of 365 or 366 days, as applicable, and applied on a daily basis) of the arithmetic mean of the secondary market bid rates as of approximately 3:30 P.M., New York City time, on such Interest Determination Date, of three leading primary United States government securities dealers in The City of New York selected by the Calculation Agent, for the issue of Treasury bills with a remaining maturity closest to the specified Index Maturity; provided, however, that if fewer than three dealers selected as aforesaid by the Calculation Agent are quoting as mentioned in this sentence, the rate of interest in effect for the applicable period will be the same as the Treasury Rate as adjusted for the Spread and/or Spread Multiplier, as the case may be, for the immediately preceding interest reset period.

        The Treasury Rate determined with respect to any Interest Determination Date will become effective on and as of the applicable Interest Reset Date specified on the face hereof; provided, however, that (i) the interest rate in effect for the period from the Original Issue Date to the first Interest Reset Date will be the Initial Interest Rate specified on the face hereof; and (ii) the interest rate in effect for the ten days immediately preceding the Stated Maturity or redemption will be that in effect on the tenth day preceding such Stated Maturity or redemption.

DETERMINATION OF CMT RATE

        If the Interest Rate Basis on this Note is the CMT Rate, the CMT Rate with respect to this Note shall equal with respect to each Interest Determination Date designated on the face hereof the rate displayed on the Designated CMT Telerate Page under the caption "...Treasury Constant Maturities.. Federal Reserve Board Release H.15... Mondays Approximately 3:45 P.M.," under the column for the Index Maturity designated on the face hereof (i) if the Designated CMT Telerate Page is 7055, the rate for the applicable Interest Determination Date and (ii) if the Designated CMT Telerate Page is 7052, the week, or the month, as applicable, ended immediately preceding the week in which the Interest

B-9

---

Determination Date occurs. If no page is specified on the face hereof, the Designated CMT Telerate Page shall be 7052, for the most recent week. If such rate is no longer displayed on the relevant page, or if not displayed by 3:00 P.M., New York City time, on the related Calculation Date, then the CMT Rate for such Interest Determination Date will be such Treasury Constant Maturity rate for the Index Maturity designated on the face hereof as published in the relevant H.15 (519). If such rate is no longer published, or if not published by 3:00 P.M., New York City time, on the related Calculation Date, then the CMT Rate for such Interest Determination Date will be such Treasury Constant Maturity rate for the Index Maturity on the face hereof (or other United States Treasury rate for such Index Maturity for that Interest Determination Date with respect to such Interest Reset Date) as may then be published by either the Federal Reserve Board or the United States Department of the Treasury that the Calculation Agent determines to be comparable to the rate formerly displayed on the Designated CMT Telerate Page and published in the relevant H.15(519). If such information is not provided by 3:00 P.M., New York City time, on the related Calculation Date, then the CMT Rate for that Interest Determination Date will be calculated by the Calculation Agent and will be a yield to maturity, based on the arithmetic mean of the secondary market closing offer side prices as of approximately 3:30 P.M. (New York City time) on that Interest Determination Date reported, according to their written records, by three leading primary United States government securities dealers (each, a "Reference Dealer") in The City of New York selected by the Calculation Agent (from five such Reference Dealers selected by the Calculation Agent and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)), for the most recently issued direct noncallable fixed rate obligations of the United States ("Treasury Note") with an original maturity of approximately the Index Maturity designated on the face hereof and a remaining term to maturity of not less than such Index Maturity minus one year. If two Treasury Notes with an original maturity as described in the preceding sentence have remaining terms to maturity equally close to the Index Maturity designated on the face hereof, the quotes for the Treasury Note with the shorter remaining term to maturity will be used. If the Calculation Agent cannot obtain three such Treasury Note quotations, the CMT Rate for that Interest Determination Date will be calculated by the Calculation Agent and will be a yield to maturity based on the arithmetic mean of the secondary market offer side prices as of approximately 3:30 P.M. (New York City time) on that Interest Determination Date of three Reference Dealers in The City of New York (from five such Reference Dealers selected by the Calculation Agent and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)), for Treasury Notes with an original maturity of the number of years that is the next highest to the Index Maturity designated on the face hereof and a remaining term to maturity closest to such Index Maturity and in an amount of at least $100 million. If three or four (and not five) of such Reference Dealers are quoting as described above, then the CMT Rate will be based on the arithmetic mean of the offer prices obtained and neither the highest nor the lowest of such quotes will be eliminated; provided, however, that if fewer than three Reference Dealers selected by the Calculation Agent are quoting as described herein, the rate of interest in effect for the applicable period will be the same as the CMT Rate as adjusted for the Spread and/or Spread Multiplier, as the case may be, for the immediately preceding Interest Reset Period.

        The CMT Rate determined with respect to any Interest Determination Date will become effective on and as of the applicable Interest Reset Date specified on the face hereof; provided, however, that (i) the interest rate in effect for the period from the Original Issue Date to the first Interest Reset Date will be the Initial Interest Rate specified on the face hereof; and (ii) the interest rate, in effect for the ten days immediately preceding the Stated Maturity or redemption will be that in effect on the tenth day preceding such Stated Maturity or redemption.

        Notwithstanding the foregoing, the interest rate hereon shall not be greater than the Maximum Interest Rate, if any, or less than the Minimum Interest Rate, if any, shown on the face hereof. The

B-10

---

Calculation Agent shall calculate the interest rate on this Note in accordance with the foregoing on each Interest Determination Date.

        The Interest Rate on this Note will in no event be higher than the maximum rate permitted by Maryland law as the same may be modified by the United States law of general applicability.

        The Calculation Agent will, upon the request of the Holder of this Note provide to such Holder the interest rate hereon then in effect and, if different, the interest rate which will become effective as of the next applicable Interest Reset Date.

        If any Interest Payment Date specified on the face hereof would otherwise be a day that is not a Business Day, the Interest Payment Date shall be postponed to the next day that is a Business Day, except that if (i) the rate of interest on this Note shall be determined in accordance with the provisions of the heading "Determination of LIBOR" above, and (ii) such Business Day is in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding Business Day. "Business Day" means any day other than a Saturday or Sunday that (a) is not a day on which banking institutions in the State of Maryland, or in New York, New York, are authorized or obligated by law or executive order to be closed, and (b) with respect to LIBOR Notes only, is a day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.

        Interest payments for this Note will include interest accrued to but excluding the Interest Payment Dates; provided, however, that if the Interest Reset Dates with respect to this Note are daily or weekly, interest payable on any Interest Payment Date, other than interest payable on any date on which principal hereof is payable, will include interest accrued to and including the Record Date next preceding such Interest Payment Date. Accrued interest hereon from the Original Issue Date or from the last date to which interest hereon has been paid, as the case may be, shall be an amount calculated by multiplying the face amount hereof by an accrued interest factor. Such accrued interest factor shall be computed by adding the interest factor calculated for each day from the Original Issue Date or from the last date to which interest shall have been paid, as the case may be, to the date for which accrued interest is being calculated. The interest factor (expressed as a decimal rounded upwards, if necessary, to the next higher one hundred-thousandth of a percentage point) for each such day shall be computed by dividing the interest rate (expressed as a decimal, rounded upwards, if necessary, to the next higher one hundred-thousandth of a percentage point) applicable to each such day by 360, in the case of the Commercial Paper Rate, CD Rate, LIBOR, Federal Funds Effective Rate or Prime Rate, or by the actual number of days in the year in the case of the Treasury Rate or the CMT Rate.

        This Note may not be redeemed by the Company prior to Stated Maturity unless otherwise set forth on the face hereof. Notwithstanding Section 4.03 of the Indenture, pursuant to Section 4.01 thereof, and if so indicated on the face of this Note, this Note may be redeemed at the option of the Company, on any date on or after the date set forth on the face hereof in whole or in part in increments of $1,000, at a redemption price or prices designated on the face hereof to be redeemed together with interest thereon payable to the date fixed for redemption. This Note may be so redeemed in whole or in part whether or not other Notes of the same series are redeemed.

        Notice of redemption or repurchase will be given by the Company by mail to holders of the Notes to be redeemed, not less than 30 nor more than 60 days prior to the date fixed for redemption, all as provided in the Indenture. The Bank may carry out the responsibilities to be performed by the Trustee required by Article 4 of the Indenture.

        The Company is not required to repurchase Notes from holders prior to Stated Maturity unless otherwise set forth on the face hereof. If so indicated on the face hereof, this Note may be repurchased by the Company at the option of the holder on the dates and at the prices designated thereon, in whole or in part in increments of $1,000, together with interest payable to the repurchase date. For book-entry notes, unless otherwise specified on the face of this Note, holders must deliver written

B-11

notice to the Bank at least 30, but no more than 60, days prior to the date of repurchase, but no later than 5:00 p.m. New York City time on the last day for giving notice. The written notice must specify the principal amount to be repurchased and must be signed by a duly authorized officer of the Depositary participant (signature guaranteed). For definitive notes, unless otherwise specified on the face of this Note, holders must complete the "Option to Elect Repayment" on the reverse of this Note and then deliver this Note to the Bank at least 30, but no more than 45, days prior to the date of repurchase, but no later than 5:00 p.m. New York City time on the last day for giving notice. All notices are irrevocable.

        In the event of redemption or repurchase of this Note in part only, a new Note or Notes of this series, having the same Stated Maturity, optional redemption or repurchase provisions, Interest Rate and other terms and provisions of this Note, in authorized denominations in an aggregate principal amount equal to the unredeemed portion hereof will be issued in the name of the holder hereof upon the surrender hereof.

        [Remarketing provisions, if any, to be included here]

        The Notes will not be subject to conversion, amortization or any sinking fund.

        As provided in the Indenture and subject to certain limitations herein and therein set forth, the transfer of this Note may be registered on the Register of the Notes, upon surrender of this Note for registration of transfer at the Bank, or at such other agencies as may be designated pursuant to the Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Trustee or the Bank duly executed by, the holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

        The Notes are issuable only as registered Notes without coupons in denominations of $1,000 or any amount in excess thereof that is an integral multiple of $1,000. As provided in the Indenture, and subject to certain limitations herein and therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes of other authorized denominations having the same Interest Rate, Stated Maturity, optional redemption or repurchase provisions, if any, and Original Issue Date, as requested by the Securityholder surrendering the same.

        No service charge will be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Company, the Trustee, the Bank, the Security registrar and any agent of the Company, the Trustee, the Bank, or the Security registrar may treat the Securityholder in whose name this Note is registered as the absolute owner hereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Note is overdue, and neither the Company, the Trustee, the Bank, the Security registrar nor any such agent shall be affected by notice to the contrary.

        If an Event of Default (as defined in the Indenture) with respect to the Notes shall occur and be continuing, the principal of all the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

        The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the holders of the Securities of any series under the Indenture at any time by the Company with the consent of the holders of not less than 66²/3% in aggregate principal amount of the Securities at the time outstanding to be affected (voting as one class). The Indenture also permits the Company and the Trustee to enter into supplemental indentures without the consent of the holders of Securities of any series for certain purposes specified in the Indenture, including the making of such other provisions in regard to matters arising under the Indenture which shall not adversely affect the interest of the holders of such Securities. The Indenture also contains provisions permitting the holders of specified percentages in

B-12

---

aggregate principal amount of the Securities of any series at the time outstanding, on behalf of the holders of all the Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note.

        The Indenture provides that no holder of any Security of any series may enforce any remedy with respect to such series under the Indenture except in the case of refusal or neglect of the Trustee to act after notice of a continuing Event of Default and after written request by the holders of not less than 25% in aggregate principal amount of the outstanding Securities of such series and the offer to the Trustee of reasonable indemnity; provided, however, that such provision shall not prevent the holder hereof from enforcing payment of the principal of or interest on this Note.

        No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

        No recourse shall be had for the payment of the principal of or the interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or 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 issue hereof, expressly waived and released.

        This Note shall be governed by and construed in accordance with the laws of the State of New York.

(REVERSE OF NOTE)

        1.    Indenture.    This Note is one of a duly authorized issue of securities of the Company designated as its Zero Coupon Senior Notes due 20            (herein called the "Notes"), issued under an indenture (herein called the "Indenture") dated as of June 19, 2008, between the Company and Deutsche Bank Trust Company Americas, as trustee (herein called the "Trustee" which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties, obligations and immunities thereunder of the Company, the Trustee and the Holders of the Notes, and of the terms upon which the Notes are, and are to be, authenticated and delivered.

        Capitalized terms used herein but not otherwise defined herein shall have the meaning assigned to such terms in the Indenture.

        The terms of the Notes include those stated in the Indenture (except as superseded by the terms set forth in the Notes) and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. § 77aaa-77bbbb) (the "TIA"); as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and the TIA for a statement of such terms.

        No reference herein to the Indenture and no provisions of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of this Note at the times, place, and rate, and in the coin or currency, herein prescribed.

        2.     Original Issue Discount. The Notes shall accrue original issue discount on a 360-day year of twelve 30-day months, compounding on each                         and                         . The "Accreted Value" of the Notes on any compounding date (each such compounding date, an "Accreted Value Calculation Date") shall be equal to the product of (i) the aggregate principal amount at maturity and (ii) the accretion factor for such date as set forth in the accretion value schedule below (the "Accretion Factor"). The "Accreted Value" of the Notes on any date between two Accreted Value Calculation Dates (an "Interim Date") shall be equal to the sum of (x) the Accreted Value on the first such Accreted Value Calculation Date and (y) the product of (A) 1/180^th of the difference between the Accreted Values on the second and the first such Accreted Value Calculation Dates and (B) the number of days (based on a 360-day year of twelve 30-day months) from and including the first of the two Accreted Value Calculation Dates to but excluding the Interim Date.

Accretion Value Schedule

        3.    Redemption and Repurchase.    The Notes are not redeemable.

        Beginning on                        , 20            and on the same day each year thereafter, holders of the Notes shall have the right to require the Company to purchase all or a portion of their Notes on the dates and at the prices set forth below in the following Prepayment Schedule. Such date is referred to herein as a "Purchase Date."

Prepayment Schedule

C-4

---

        The purchase prices shown above are equal to the original issue price plus accrued original issued discount to the applicable Purchase Date. A holder of a Note electing to require the Company to purchase all or a portion of their Notes must provide written notice via facsimile and courier to the trustee and the Company at least 20 Business Days prior to a Purchase Date. Such notice shall state (i) the portion of the principal amount at maturity of the Notes that such holder is electing to have purchased, which must be $1,000,000 principal amount at maturity or an integral multiple of $1,000 in excess thereof, (ii) that the Notes are to be purchased pursuant to the applicable provisions of the Notes and (iii) the applicable purchase price, as indicated in the above Prepayment Schedule.

        The Company's obligation to pay the purchase price of Notes, for which a written notice has been delivered is conditioned upon the holder delivering the Notes (through the facilities of The Depositary Trust Company ("DTC") while the Notes are registered and held by DTC) specified in the written notice, together with the necessary endorsements, to the trustee at any time after delivery of the written notice. The Company shall cause the purchase price for such Notes to be paid promptly following the later of the Purchase Date or the time of delivery of the Notes, provided that if such day is not a Business Day, the payment of the purchase price may be made on the next succeeding Business Day, as if it were made on the date this payment was due, and no original issue discount shall accrue as a result of this delayed payment. If the trustee holds money sufficient to pay the purchase price of the Notes on the Purchase Date, then, whether or not such Notes are delivered to the trustee, original issue discount on such Notes will cease to accrue beginning on the Purchase Date and, immediately after the Purchase Date, such Notes shall cease to be outstanding. Thereafter, all other rights of the holders of such Notes shall terminate, other than the right to receive the purchase price upon delivery of such Notes.

        4.    Defaults and Remedies.    If an Event of Default occurs and is continuing, the Accreted Value of all of the Outstanding Notes of this series on the date the Notes are paid (rather than the principal amount as provided in the Indenture), may be declared due and payable in the manner and with the effect provided in the Indenture.

        5.    Amendment and Waivers.    The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the holders of the Securities of any series under the Indenture at any time by the Company with the consent of the holders of not less than 66²/3% in aggregate principal amount of the Securities at the time Outstanding to be affected (voting as one class). The Indenture also permits the Company and the Trustee to enter into supplemental indentures without the consent of the holders of Securities of any series for certain purposes specified in the Indenture, including the making of such other provisions in regard to matters arising under the Indenture which shall not adversely affect the interest of the holders of such Securities. The Indenture also contains provisions permitting the holders of specified percentages in aggregate principal amount of the Securities of any series at the time Outstanding, on behalf of the holders of all the Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note.

        The Indenture provides that no holder of any Security of any series may enforce any remedy with respect to such series under the Indenture except in the case of refusal or neglect of the Trustee to act after notice of a continuing Event of Default and after written request by the holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such series and the offer to the Trustee of reasonable indemnity; provided, however, that such provision shall not prevent the holder hereof from enforcing payment of the principal of or interest on this Note.

C-5

---

        In addition to clauses (i) and (ii) of Section 11.02 of the Indenture, no such supplemental indenture or waiver (including a waiver pursuant to Section 7.07 of the Indenture) shall, without the consent of the Holder of each Outstanding Note affected thereby:

        (iii)  alter the Company's obligation to purchase Notes as it arises hereunder;

        (iv)  alter the calculation of Accreted Value; or
