The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is limited to $130.0 million (or $149.5 million if the Underwriters' over-allotment option set forth in Section 2 of the Underwriting Agreement is exercised in full), except for Securities authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of other Securities pursuant to Sections 2.7, 2.8, 2.12, 7.5, 10.7, 11.1 or 12.2 hereof. The Securities shall be issuable in denominations of $1,000 or integral multiples thereof.

        (b) The Securities shall mature on July 15, 2006 (the "Stated Maturity").

        (c) The Securities shall bear Interest from July 5, 2001 until the principal amount thereof is paid or made available for payment, or until such date on which the Securities are converted, redeemed or purchased as provided herein, (i) prior to the occurrence of a Reset Transaction, at a rate of 53/4% per annum, and (ii) following the occurrence of a Reset Transaction, at the Adjusted

D–10

    Interest Rate related to such Reset Transaction to, but not including, the effective date of any succeeding Reset Transaction (as adjusted, if at all, the "Interest Rate"). Interest shall be payable semiannually in arrears on each Interest Payment Date.

        (d) Interest on the Securities shall be computed (i) for any full semi-annual period for which a particular Interest Rate is applicable, on the basis of a 360-day year of twelve 30-day months and (ii) for any period for which a particular Interest Rate is applicable for less than a full semiannual period for which interest is calculated, on the basis of a 30-day month and, for such periods of less than a month, the actual number of days elapsed over a 30-day month. For purposes of determining the Interest Rate, the Trustee may assume that a Reset Transaction has not occurred unless the Trustee has received an Officers' Certificate stating that a Reset Transaction has occurred and specifying the Adjusted Interest Rate then in effect.

        (e) Interest shall be due and payable on a Security as follows:

          (1) A registered Holder of any Security as of the close of business on a Regular Record Date shall be entitled (except as otherwise indicated in this Section 2.1(e)) to receive and shall receive, as the registered Holder as of such Regular Record Date, Interest on such Security on the corresponding Interest Payment Date (other than any Security whose Stated Maturity is prior to such Interest Payment Date).

          (2) In the event that a Security becomes subject to redemption pursuant to Article 10 and the Redemption Date occurs after a Regular Record Date, the Person whose Securities become subject to redemption (and only such Person rather than the Holder as of such Regular Record Date) shall be entitled to receive and shall receive accrued and unpaid Interest from the preceding Interest Payment Date (or such earlier date on which Interest was last paid) to but not including the Redemption Date on such Security, even if such person is not the Holder of such Security.

          (3) In the event that a Security becomes subject to purchase pursuant to Article 11, a Holder of any Security who exercises a purchase right with respect to such Security shall be entitled to receive and shall receive Interest to but not including the applicable purchase date for such Security, which amount shall be included in the applicable purchase price thereof.

          (4) In the event that a Security is converted pursuant to Article 12, the Holder who converts such Security on any date other than an Interest Payment Date shall not be entitled to accrued and unpaid Interest from the preceding Interest Payment Date until the Conversion Date, or otherwise, on such Security, such amounts being deemed to have been paid by receipt of shares of Common Stock in full rather than canceled, extinguished or forfeited; and, accordingly, a Holder which converts a Security after a Regular Record Date but prior to the corresponding Interest Payment Date will receive accrued and unpaid Interest for such period on such Interest Payment Date but will be required to remit to the Company an amount equal to that Interest at the time such Holder surrenders the Security for conversion, provided that such Holder will not be required to remit such Interest if, prior to conversion, the Company has called such Security for redemption and the Holder converts such Security prior to the applicable Redemption Date.

        (f)  Payment of any Principal of (to the extent paid in cash) and Interest on Global Securities shall be payable by the Company to the Depositary in immediately available funds.

        (g) Payment of any Principal on Physical Securities shall be made at the office or agency of the Company maintained for such purpose, initially the Corporate Trust Office of the Trustee.

D–11

    a Holder of a principal amount of Securities in excess of $5,000,000, wire transfer in immediately available funds, which application shall remain in effect until the Holder notifies, in writing, the Registrar to the contrary.

        (h) The Securities may be redeemable at the option of the Company as provided in and subject to Article 10.

        (i)  The Securities shall be purchased by the Company at the option of Holders as provided in and subject to Article 11.

        (j)  The Securities shall be convertible at the option of the Holders as provided in and subject to Article 12.

        (a) Two Officers shall execute the Securities on behalf of the Company by manual or facsimile signature. Securities bearing the manual or facsimile signatures of individuals who were at the time of the execution of the Securities the proper Officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of authentication of such Securities.

        (b) At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise. No Security shall be entitled to any benefit under this Indenture, or be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by or on behalf of the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. The Trustee may appoint an authenticating agent or agents reasonably acceptable to the Company with respect to the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.

        (c) Each Security shall be dated the date of its authentication. The Trustee shall authenticate and deliver Securities for original issue in an aggregate principal amount of up to $130.0 million, (or $149.5 million if the Underwriters' over-allotment option set forth in Section 2 of the Underwriting Agreement is exercised in full) upon one or more Company Orders without any further action by the Company. The aggregate principal amount of Securities Outstanding at any time may not exceed the amount set forth in the foregoing sentence.

        (1) as Paying Agent in connection with redemptions, offers to purchase and discharges, except as otherwise specified in this Indenture, and

    The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money and Common Stock held by the Paying Agent for the making of payments in respect of the Securities and shall notify the Trustee of any Default by the Company in making any such payment. At any time during the continuance of any such Default, the Paying Agent shall, upon the written request of the Trustee, forthwith pay to the Trustee all money and Common Stock so held in trust.

    If the Company shall act as a Paying Agent, it shall, prior to or on each such due date, segregate and hold in trust for the benefit of the Holders a sum sufficient with monies held by all other Paying Agents, to pay such amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as provided in this Indenture, and shall promptly notify the Trustee of its action or failure to act.

A Holder may transfer a Security only by written application to the Registrar stating the name of the proposed transferee and otherwise complying with the terms of this Indenture.

Subject to Section 2.4, to permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar's request. No service charge shall be made for any registration of transfer or exchange or redemption of the Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or other similar governmental charge payable upon exchanges pursuant to Sections 2.14, 7.5 or 10.7).

    Neither the Company nor the Registrar shall be required to exchange or register a transfer of any Securities:

        (1) for a period of 15 days prior to the day of any selection of Securities for redemption under Article 10 hereof;

        (2) so selected for redemption or, if a portion of any Security is selected for redemption, such portion thereof selected for redemption; or

        (2) be delivered to the Trustee as custodian for such Depositary, for credit to the accounts of the members of, participants in, the Depositary (the "Agent Members") holding the Securities evidenced thereby (or in the case of Securities held for purchasers who acquired such Securities, registered with the Depositary for credit to the accounts of the Agent Members then holding such Securities on behalf of Euroclear or Clearstream, as applicable).

    Agent Members shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under such Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing contained herein shall prevent the Company, the Trustee or any agent of the Company or Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and the Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security. With respect to any Global Security deposited on behalf of the subscribers for the Securities represented thereby with the Trustee as custodian for the Depositary for credit to their respective accounts (or to such other accounts as they may direct) at Euroclear or Clearstream, the provisions of the "Operating Procedures of the Euroclear System" and the "Terms and Conditions Governing Use of Euroclear" and the "Management Regulations" and "Instructions to Participants" of Clearstream, respectively, shall be applicable to the Global Securities.

    (b) The registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities.

D–15

        (2) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Physical Securities under this Indenture in exchange for all or any part of the Securities represented by a Global Security or Global Securities; or

        (3) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depositary for the issuance of Physical Securities in exchange for such Global Security or Global Securities,

then the Depositary shall surrender such Global Security or Global Securities to the Trustee for cancellation and the Company shall execute, and the Trustee, upon receipt of an Officers' Certificate and Company Order for the authentication and delivery of Securities, shall authenticate and deliver in exchange for such Global Security or Global Securities, Physical Securities in an aggregate principal amount equal to the aggregate principal amount of such Global Security or Global Securities. Such Physical Securities shall be registered in such names as the Depositary shall identify in writing as the beneficial owners of the Securities represented by such Global Security or Global Securities (or any nominee thereof).

    (e) Notwithstanding the foregoing, in connection with any transfer of beneficial interests in a Global Security to the beneficial owners thereof pursuant to Section 2.8(d) hereof, the Registrar shall reflect on its books and records the date and a decrease in the aggregate principal amount of such Global Security in an amount equal to the aggregate principal amount of the beneficial interest in such Global Security to be transferred.

    Section 2.9.  Holder Lists.  

    The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply with Section 312(a) of the TIA. If the Trustee is not the Registrar, the Company shall furnish to the Trustee prior to or on each Interest Payment Date and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders relating to such Interest Payment Date or request, as applicable.

    Section 2.10.  Persons Deemed Owners.  

    Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of the Security or the payment of any Redemption Price or Change of Control Purchase Price in respect thereof and Interest thereon, if any, for any purpose under this Indenture, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

D–16

    Section 2.11.  Mutilated, Destroyed, Lost or Stolen Securities.  

    If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and aggregate principal amount and bearing a number not contemporaneously outstanding.

    If there is delivered to the Company and the Trustee

        (1) evidence to their satisfaction of the destruction, loss or theft of any Security, and

        (2) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of actual notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and, upon request, the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, and bearing a number not contemporaneously outstanding.

    In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion, but subject to any conversion rights, may, instead of issuing a new Security, pay such Security, upon satisfaction of the condition set forth in the preceding paragraph.

    Upon the issuance of any new Security under this Section, the Company 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 the fees and expenses of the Trustee) connected therewith.

    Every new Security issued pursuant to this Section 2.11 in lieu of any destroyed, lost or stolen Security shall constitute an original contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

    The provisions of this Section 2.11 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

    Section 2.12.  Treasury Securities.  

    In determining whether the Holders of the requisite principal amount of Outstanding Securities are present at a meeting of Holders for quorum purposes or have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the Company or any Affiliate of the Company shall be disregarded and deemed not to be Outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such determination as to the presence of a quorum or upon any such request, demand, authorization, direction, notice, consent or waiver, only such Securities of which the Trustee has received written notice and are so owned shall be so disregarded.

    Section 2.13.  Temporary Securities.  

    Pending the preparation of Securities in definitive form, the Company may execute and the Trustee shall, upon written request of the Company, authenticate and deliver temporary Securities (printed or lithographed). Temporary Securities shall be issuable in any authorized denomination, and substantially in the form of the Securities in definitive form but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every such temporary Security shall be executed by the Company and authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the Securities in definitive form. Without unreasonable delay, the Company will execute and deliver to the Trustee

D–17

Securities in definitive form (other than in the case of Securities in global form) and thereupon any or all temporary Securities (other than any such Securities in global form) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 9.2 and the Trustee shall authenticate and deliver in exchange for such temporary Securities an equal principal amount of Securities in definitive form. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Securities in definitive form authenticated and delivered hereunder.

    Section 2.14.  Cancellation.  

    All Securities surrendered for payment, redemption, purchase, conversion, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities so delivered shall be canceled promptly by the Trustee, and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. Upon written instructions of the Company, the Trustee shall dispose of canceled Securities in accordance with its procedures for the disposition of cancelled securities in effect as of the date of such disposition. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless the same are delivered to the Trustee for cancellation.

    Section 2.15.  CUSIP Numbers.  

    The Company in issuing the Securities may use "CUSIP" numbers (if then generally in use), and the Trustee shall use CUSIP numbers in notices of redemption or exchange as a convenience to Holders; provided that any such notice shall state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any such notice 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 Company shall promptly notify the Trustee of any change in the CUSIP numbers.

    Section 2.16.  Defaulted Interest.  

    If the Company fails to make a payment of Principal of or Interest on any Security when due and payable, it shall pay such Interest on such amounts (to the extent lawful), which shall be calculated using the applicable Interest Rate (such amounts, the "Defaulted Interest"); provided that, if the Company elects to satisfy its obligation to pay the Change of Control Price in Common Stock pursuant to Section 11.1 and fails to have such shares delivered to the applicable Holders, then it shall pay Defaulted Interest on the amount of cash that would otherwise have been payable pursuant to Section 11.1 if it had not made that election. It may elect to pay such Defaulted Interest, plus any other Interest payable on it, to the Persons who are Holders on which the interest is due on a subsequent special record date. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Security. The Company shall fix any such special record date and payment date for such payment. At least 15 days before any such special record date, the Company shall mail to Holders affected thereby a notice that states the special record date, the Interest Payment Date and amount to be paid.


ARTICLE 3

DISCHARGE of indenture

    Section 3.1. Discharge of Liability on Securities.  When (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.11) for cancellation or (ii) all outstanding Securities have become due and payable at their scheduled maturity within one year or all outstanding Securities are scheduled for redemption within one year and the Company deposits

D–18

with the Trustee cash or, in the event of a conversion pursuant to Article 12, Common Stock, sufficient to pay all amounts due and owing on all outstanding Securities on the date of their scheduled maturity or the scheduled date of redemption (other than Securities replaced pursuant to Section 2.11), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 5.8, cease to be of further effect. The Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers' Certificate and Opinion of Counsel and at the cost and expense of the Company.

    Section 3.2. Repayment to the Company.  The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee and the Paying Agent shall have no further liability to the Holders with respect to such money or securities for that period commencing after the return thereof.


ARTICLE 4

DEFAULTS AND REMEDIES

    Section 4.1. Events of Default.  An "Event of Default", wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

    (a) the Company defaults in the payment of the Principal amount (a "Defaulted Payment") on any Outstanding Security when the same becomes due and payable at its Stated Maturity, upon redemption, purchase, upon declaration, when due for purchase, by the Company or otherwise;

    (b) the Company defaults in the payment of an installment of Interest on any Security when it becomes due and payable and such default continues for a period of 30 days, whether or not such payment is prohibited by Article 13 hereof;

    (c) the Company fails to perform or observe any other term, covenant or agreement contained in the Securities or this Indenture and the default continues for a period of 60 days after written notice of such failure, requiring the Company to remedy the same, shall have been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Securities;

    (d) the Company defaults under any Indebtedness for money borrowed by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, the aggregate outstanding principal amount of which is in an amount in excess of $20.0 million, for a period of 60 days after written notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% in aggregate principal amount of the Outstanding Securities, which default (i) is caused the Company's failure to pay when due principal or premium of or interest on such Indebtedness by the end of the applicable grace period, if any, unless such Indebtedness is discharged or (ii) results in the acceleration of such Indebtedness because of a default with respect to such Indebtedness without such Indebtedness having been discharged or such non-payment or acceleration having been cured, waived, rescinded or annulled;

    (e) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, in an involuntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or

D–19

other similar law or (ii) a decree or order adjudging the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, under any applicable U.S. federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or

    (f) the commencement by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, of a voluntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, to the entry of a decree or order for relief in respect of the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, in an involuntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company, or the filing by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, of a petition or answer or consent seeking reorganization or relief under any applicable U.S. federal or state law, or the consent by the Company to the filing of such petition or to the appointment of or the taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or the making by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, of an assignment for the benefit of creditors, or the admission by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, expressly in furtherance of any such action.

    A Default under clause (c) or (d) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% of the principal amount of the Securities at the time outstanding notify the Company and the Trustee, of the Default and the Company does not cure such Default (and such Default is not waived) within the time specified in clause (c) or (d) above after actual receipt of such notice. Any such notice must specify the Default, demand that it be remedied and state that such notice is a "Notice of Default".

    The Trustee shall, within 90 days of the occurrence of a Default, give to the Holders of the Securities notice of all uncured Defaults known to it and written notice of any event which with the giving of notice or the lapse of time, or both, would become an Event of Default, its status and what action the Company is taking or proposes to take with respect thereto; provided, however, the Trustee shall be protected in withholding such notice if it, in good faith, determines that the withholding of such notice is in the best interest of such Holders, except in the case of a Default in the payment of the Principal of or Interest on any of the Securities when due or in the payment of any redemption or Purchase Right.

D–20

    Section 4.2.  Acceleration of Maturity; Rescission and Annulment.  

    If an Event of Default with respect to Outstanding Securities (other than an Event of Default specified in Section 4.1(e) or 4.1(f) hereof) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Outstanding Securities, by written notice to the Company, may declare due and payable 100% of the principal amount of all Outstanding Securities, plus any accrued and unpaid Interest to the date of payment. Upon a declaration of acceleration, such Principal amount and accrued and unpaid Interest to the date of payment shall be immediately due and payable.

    If an Event of Default specified in Section 4.1(e) and 4.1(f) occurs, the Principal and accrued and unpaid Interest on the Outstanding Securities shall become and be immediately due and payable, without any declaration or other act on the part of the Trustee or any Holder.

    The Holders either (a) through notice to the Trustee of not less than a majority of the principal amount of the Outstanding Securities, or (b) by the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of at least a majority of the principal amount of the Outstanding Securities represented at such meeting, may, on behalf of the Holders of all of the Securities, rescind and annul an acceleration and its consequences (including waiver of any defaults) if:

        (1) all existing Events of Default, other than the nonpayment of a Defaulted Payment on the Securities which have become due solely because of the acceleration, have been remedied, cured or waived, and

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

provided, however, that in the event such declaration of acceleration has been made based on the existence of an Event of Default under Section 4.1(d) and the default with respect to Indebtedness for money borrowed which gave rise to such Event of Default has been remedied, cured or waived, then, without any further action by the Holders, such declaration of acceleration shall be rescinded automatically and the consequences of such declaration shall be annulled. No such rescission or annulment shall affect any subsequent Default or impair any right consequent thereon.

    Section 4.3.  Other Remedies.  

    If an Event of Default with respect to Outstanding Securities occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the Defaulted Payment or Interest due and payable on the Securities or to enforce the performance of any provision of the Securities.

    The Trustee may maintain a proceeding in which it may prosecute and enforce all rights of action and claims under this Indenture or the Securities, even if it does not possess any of the Securities or does not produce any of them in the proceeding.

    Section 4.4.  Waiver of Past Defaults.  

    The Holders, either (a) through the written consent of not less than a majority of the principal amount of the Outstanding Securities, or (b) by the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of at least a majority of the principal amount of the Outstanding Securities represented at such meeting, may, on behalf of the Holders of all of the Securities, waive an existing Default or Event of Default, except a Default or Event of Default:

        (1) set forth in Sections 4.1(a) and (b), provided, however, that subject to Section 4.7, the Holders of a majority of the principal amount of the Outstanding Securities may rescind an

D–21

    acceleration and its consequences, including any related payment default that resulted from such acceleration); or

        (2) in respect of a covenant or provision hereof which, under Section 7.2 hereof, cannot be modified or amended without the consent of the Holders of each Outstanding Security affected.

    Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; provided, however, that no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

    Section 4.5.  Control by Majority.  

    The Holders of a majority of the principal amount of the Outstanding Securities (or such lesser amount as shall have acted at a meeting pursuant to the provisions of this Indenture) shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that:

        (1) conflicts with any law or with this Indenture;

        (2) the Trustee determines may be unduly prejudicial to the rights of the Holders not joining therein; or

        (3) may expose the Trustee to personal liability.

    The Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

    Section 4.6.  Limitation on Suit.  

    No Holder of any Security shall have any right to pursue any remedy with respect to this Indenture or the Securities (including, instituting any proceeding, judicial or otherwise, with respect to this Indenture or for the appointment of a receiver or trustee) unless:

        (1) such Holder has previously given written notice to the Trustee of an Event of Default that is continuing;

        (2) the Holders of at least 25% of the principal amount of the Outstanding Securities shall have made written request to the Trustee to pursue the remedy;

        (3) such Holder or Holders have offered to the Trustee indemnity satisfactory to it against any costs, expenses and liabilities incurred in complying with such request;

        (4) the Trustee has failed to comply with the request for 60 days after its receipt of such notice, request and offer of indemnity; and

        (5) during such 60-day period, no direction inconsistent with such written request has been given to the Trustee by the Holders of a majority of the principal amount of the Outstanding Securities (or such amount as shall have acted at a meeting pursuant to the provisions of this Indenture);

provided, however, that no one or more of such Holders may use this Indenture to prejudice the rights of another Holder or to obtain preference or priority over another Holder.

    Section 4.7.  Unconditional Rights of Holders to Receive Payment and to Convert.  

    Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the Principal on and Interest in respect of the Securities held by such Holder, on or after the respective due dates, to convert the

D–22

Securities in accordance with Article 12 or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, and such rights shall not be impaired or affected adversely without the consent of such Holder.

    Section 4.8.  Collection of Indebtedness and Suits for Enforcement by the Trustee.  

    The Company covenants that if:

        (1) a Default or Event of Default is made in the payment of Interest on any Security when such Interest becomes due and payable and such Default or Event of Default continues for a period of 30 days; or

        (2) a Default or Event of Default is made in the payment of the Principal on any Security when the same becomes due and payable at its Stated Maturity, upon redemption, upon declaration when due for purchase by the Company or otherwise,

then the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the entire Principal then due and payable (as expressed therein or as a result of any acceleration effected pursuant to Section 4.2 hereof) on such Securities for any such amounts and, to the extent legally enforceable, Interest on such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

    If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company, wherever situated.

    If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

    Section 4.9.  Trustee May File Proofs of Claim.  

    In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or the property of the Company or its creditors, the Trustee (irrespective of whether the Principal 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 on the Company for the payment of any such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise:

        (1) to file and prove a claim for the whole amount of the Principal or Interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders of Securities allowed in such judicial proceeding and

        (2) to collect and receive any monies, Common Stock or other property payable or deliverable on any such claim and to distribute the same,

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceedings is hereby authorized by each Holder of Securities to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of Securities, to pay to the Trustee any amount due to it for the reasonable compensation,

D–23

expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 5.8.

    Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept, or adopt on behalf of any Holder of a Security, any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder of a Security in any such proceeding.

    Section 4.10.  Restoration of Rights and Remedies.  

    If the Trustee or any Holder of a Security has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders of Securities shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

    Section 4.11.  Rights and Remedies Cumulative.  

    Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 2.11, no right or remedy conferred in this Indenture upon or reserved to the Trustee or to the Holders of Securities is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

    Section 4.12.  Delay or Omission Not Waiver.  

    No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders of Securities may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Securities, as applicable.

    Section 4.13.  Priorities.  

    Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee:

        FIRST: to the payment of all amounts due to the Trustee under Section 5.8;

        SECOND: to Holders for amounts due and unpaid on the Securities for the Principal or Interest as applicable, ratably, without preference or priority of any kind, according to such amounts due and payable on the Securities; and

        THIRD: any remaining amounts shall be repaid to the Company.

    The Trustee may fix a special record date and payment date for any payment to Holders pursuant to this Section 4.13. At least 15 days before such special record date, the Trustee shall mail to each Holder and the Company a notice that states the special record date, the payment date and the amount to be paid.

D–24

    Section 4.14.  Undertaking for Costs.  

    All parties to this Indenture agree, and each Holder of any Security by such Holder's acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% of the principal amount of the Outstanding Securities, or to any suit instituted by any Holder of any Security for the enforcement of (i) payments pursuant to Section 4.7, repurchase rights in accordance with Article 11 or (iii) conversion rights in accordance with Article 12. This Section 4.14 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA.

    Section 4.15.  Waiver of Stay or Extension Laws.  

    The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim to take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.


ARTICLE 5

THE TRUSTEE

    Section 5.1.  Certain Duties and Responsibilities.  

    (a) Except during the continuance of an Event of Default,

        (1) The Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture or the TIA, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

        (2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; provided, however, that in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates or opinions to determine whether or not, on their face, they conform to the requirements to this Indenture (but need not investigate or confirm the accuracy of any facts stated therein).

    (b) In case an Event of Default actually known to a Responsible Officer of the Trustee has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs.

    (c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

        (1) This paragraph (c) shall not be construed to limit the effect of paragraph (a) of this Section 5.1;

    (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers.

    Section 5.2.  Certain Rights of Trustee.  

    Subject to the provisions of Section 5.1 hereof and subject to Section 315(a) through (d) of the TIA:

        (1) The Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

        (2) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel, or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers' Certificate or Opinion of Counsel.

        (3) The Trustee may act through attorneys and agents and shall not be responsible for the misconduct or negligence of any attorney or agent appointed with due care.

        (4) The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith which it believed to be authorized or within the discretion or rights or powers conferred upon it by this Indenture, unless the Trustee's conduct constitutes negligence.

        (5) The Trustee may consult with counsel of its selection and the advice of such counsel as to matters of law or legal interpretation shall be full and complete authorization and protection in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

        (6) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company.

        (7) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty unless so specified herein.

    Section 5.3.  Individual Rights of Trustee.  

    The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as such term is defined in Section 310(b) of the TIA), it must eliminate such conflict within 90 days, apply to the Commission for permission to continue as trustee (to the extent permitted under Section 310(b) of the TIA) or resign. Any agent may do the same with like rights and duties. The Trustee is also subject to Sections 5.11 and 5.12 hereof.

    Section 5.4.  Money Held in Trust.  

    Money held by the Trustee in trust hereunder shall not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise expressly agreed with the Company.

    Section 5.5.  Trustee's Disclaimer.  

    The recitals contained herein and in the Securities (except for those in the certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity, sufficiency or priority of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of Securities or the proceeds thereof.

    Section 5.6.  Notice of Defaults.  

    Within 90 days after the occurrence of any Default or Event of Default hereunder of which a Responsible Officer of the Trustee has received written notice, the Trustee shall give notice to Holders,

D–27

unless such Default or Event of Default shall have been cured or waived; provided, however, that, except in the case of a Default or Event of Default described in Sections 4.1(a) or (b), the Trustee shall be protected in withholding such notice if and so long as Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders. The second sentence of this Section 5.6 shall be in lieu of the proviso to Section 315(b) of the TIA and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA. The Trustee shall not be deemed to have knowledge of a Default unless a Responsible Officer of the Trustee has received written notice of such Default.

    Section 5.7.  Reports by Trustee to Holders.  

    The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required by Section 313 of the TIA at the times and in the manner provided by the TIA.

    A copy of each report at the time of its mailing to Holders shall be filed with the SEC, if required, and each stock exchange, if any, on which the Securities and the Common Stock are listed. The Company shall promptly notify the Trustee when the Securities or the Common Stock become listed on any stock exchange.

    Section 5.8.  Compensation and Indemnification.  

    The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation as agreed to in writing by the Trustee and the Company (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) and the Company covenants and agrees to pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ), except to the extent that any such expense, disbursement or advance is due to its negligence or bad faith. When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 4.1, the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any bankruptcy law. The Company also covenants to indemnify the Trustee and its officers, directors, employees and agents for, and to hold such Persons harmless against, any loss, liability or expense incurred by them, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder or the performance of their duties hereunder, including the costs and expenses of defending themselves against or investigating any claim of liability in the premises, except to the extent that any such loss, liability or expense was due to the negligence or willful misconduct of such Persons. The obligations of the Company under this Section 5.8 to compensate and indemnify the Trustee and its officers, directors, employees and agents and to pay or reimburse such Persons for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee. Such additional indebtedness shall be a lien prior to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities, and the Securities are hereby subordinated to such senior claim. "Trustee" for purposes of this Section 5.8 shall include any predecessor Trustee, in its capacity as Trustee, but the negligence or willful misconduct of any Trustee shall not affect the indemnification of any other Trustee.

    Section 5.9.  Replacement of Trustee.  

    A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section 5.9.

D–28

    The Trustee may resign and be discharged from the trust hereby created by so notifying the Company in writing. The Holders of at least a majority of the principal amount of Outstanding Securities may remove the Trustee by so notifying the Trustee and the Company in writing. The Company must remove the Trustee if:

        (i)  the Trustee fails to comply with Section 5.10 hereof or Section 310 of the TIA;

        (ii) the Trustee becomes incapable of acting;

        (iii) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; or

        (iv) a Custodian or public officer takes charge of the Trustee or its property.

    If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason, the Company shall promptly appoint a successor Trustee. The Trustee shall be entitled to payment of its fees and reimbursement of its expenses while acting as Trustee. Within one year after the successor Trustee takes office, the Holders of at least a majority of the principal amount of Outstanding Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

    Any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee if the Trustee fails to comply with Section 5.10.

    If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation or removal, the resigning or removed Trustee, as applicable, may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee.

    A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The Company shall issue a notice of the successor Trustee's succession to the Holders. Upon payment of its charges, the retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject nevertheless to its lien, if any, provided for in Section 5.8 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 5.9 hereof, the Company's obligations under Section 5.8 hereof shall continue for the benefit of the retiring Trustee with respect to expenses, losses and liabilities incurred by it prior to such replacement.

    Section 5.10.  Successor Trustee by Merger, Etc.  

    Subject to Section 5.11 hereof, if the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation or national banking association, the successor entity without any further act shall be the successor Trustee as to the Securities.

    Section 5.11.  Corporate Trustee Required; Eligibility.  

    The Trustee shall at all times satisfy the requirements of Section 310(a)(1), (2) and (5) of the TIA. The Trustee shall at all times have (or, in the case of a corporation included in a bank holding company system, the related bank holding company shall at all times have), a combined capital and surplus of at least $50 million as set forth in its (or its related bank holding company's) most recent published annual report of condition. The Trustee is subject to Section 310(b) of the TIA.

D–29

    Section 5.12.  Collection of Claims Against the Company.  

    The Trustee is subject to Section 311(a) of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated therein.

In the event of any such conveyance or transfer, the Company (which term shall for this purpose mean the Person named as the "Company" in the first paragraph of this Indenture or any successor Person which shall theretofore become such in the manner described in Section 6.1 hereof),

D–30

except in the case of a lease to another Person, the predecessor corporation shall be relieved of all obligations and covenants under this Indenture and the Securities and may be dissolved and liquidated.

    (a) At any time on or after July 15, 2004, except for Securities that it is required to purchase pursuant to Section 11.1 or required to convert pursuant to Section 12.1, the Company may, at its option, redeem the Securities in whole at any time or in part from time to time, on any date prior to the Stated Maturity of such Securities, upon notice as set forth in Section 10.4, at the Redemption Price (expressed in percentages of the principal amount) set forth below if, but only if, redeemed on a Redemption Date occurring during the 12-month period beginning on of the dates indicated:

During the Twelve Months Commencing
   Redemption
Price
July 15, 2004   102.8750%
July 15, 2005   101.4375%

    (b) If the Company exercises its option to redeem the Securities pursuant to this Section 10.1, a Holder may nevertheless exercise its right to have its Securities purchased pursuant to Section 11.1, if applicable, and to convert such Securities pursuant to Article 12, in each case, until the close of business two Business Days immediately preceding the Redemption Date.

    (c) The Company shall pay any Interest to the Holder of the Securities called for redemption (including those Securities which are converted into Common Stock after the date the notice of the redemption is mailed and prior to the Redemption Date) accrued but not paid to, but excluding, the Redemption Date pursuant to Section 2.1(e); provided, however, that if the Redemption Date is an Interest Payment Date, the Company shall pay the Interest to the Holder of the Security at the close of business on such Interest Payment Date.

    Section 10.2.  Notice to Trustee.  

    If the Company elects to redeem Securities pursuant to the provisions of Section 10.1 hereof (such election to be ordered by a Board Resolution), it shall notify the Trustee at least 20 days prior to the intended Redemption Date (unless a shorter notice shall be satisfactory to the Trustee) of (i) such intended Redemption Date, (ii) the principal amount of Securities to be redeemed and (iii) the CUSIP numbers of the Securities to be redeemed.

    Section 10.3.  Selection of Securities to Be Redeemed.  

    If fewer than all the Securities are to be redeemed, the Trustee shall select the particular Securities to be redeemed from the Outstanding Securities by a method that complies with the requirements of any exchange on which the Securities are listed, or, if the Securities are not listed on an exchange, on a pro rata basis or by lot or in accordance with any other method the Trustee considers fair and appropriate. The Trustee may select for redemption portions of the principal amount of Securities that have denominations larger than $1,000.

    Securities and portions thereof that the Trustee selects shall be in principal amounts in integral multiples of $1,000. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed.

    The Trustee shall promptly notify the Company and the Registrar 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.

D–37

    If any Security selected for partial redemption is converted or elected to be purchased in part before termination of the conversion right or purchase right with respect to the portion of the Security so selected, the converted or purchased portion of such Security shall be deemed to be the portion selected for redemption; provided, however, that the Holder of such Security so converted or purchased and deemed redeemed shall not be entitled to any additional interest payment as a result of such deemed redemption than such Holder would have otherwise been entitled to receive upon conversion or purchase of such Security subject to Section 2.1(e). Securities which have been converted or purchased during a selection of Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection.

    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 Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

    Section 10.4.  Notice of Redemption.  

    Notice of redemption shall be given in the manner provided in Section 14.2 to the Holders of Securities to be redeemed. Such notice shall be given not less than 20 nor more than 60 days prior to the intended Redemption Date.

        (5) the Conversion Price, the date on which the right to convert the principal of the Securities to be redeemed will terminate and the places where such Securities may be surrendered for conversion;

        (6) the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued and unpaid Interest, and

        (7) the CUSIP number of the Securities.

    The notice given shall specify the last date on which exchanges or transfers of Securities may be made pursuant to Section 2.7, and shall specify the serial numbers of Securities and the portions thereof called for redemption.

    Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company's written requests delivered at least 20 days prior to the date of the mailing of such Notice (unless a shorter period shall be acceptable to the Trustee), by the Trustee in the name of and at the expense of the Company.

    Section 10.5.  Effect of Notice of Redemption.  

    Notice of redemption having been given as provided in Section 10.4 hereof, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein

D–38

specified and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid Interest) such Securities shall cease to bear Interest. Upon surrender of any such Security for redemption in accordance with such notice, such Security shall be paid by the Company at the Redemption Price; provided, however, the installments of Interest on Securities whose Stated Maturity is prior to or on the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Regular Record Date.

    If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and premium, if any, shall, until paid, bear Interest from the Redemption Date at the Interest Rate.

    Section 10.6.  Deposit and Payment of Redemption Price.  

    Prior to or on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.4) an amount of money in immediately available funds sufficient to pay the Redemption Price, and accrued and unpaid Interest in respect of all the Securities to be redeemed on that Redemption Date from the last Interest Payment Date to but not including the Redemption Date, other than any Securities called for redemption on that date which have been converted prior to the date of such deposit, and accrued and unpaid Interest on such Securities. The Trustee and Paying Agent shall then cause such funds to be paid to the Holders of the Securities being redeemed in accordance with this Article.

    If any Security delivered for redemption shall not be so redeemed by payment to the Holders thereof on the Redemption Date, the principal amount of such Security shall, until it is redeemed, bear Interest on the Redemption Date to but not including the actual date of redemption at the applicable Interest Rate, and each such Security shall remain convertible into shares of Common Stock pursuant to Article 12 until such Security shall have been so redeemed.

    If any Security called for redemption is converted, any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive Interest as provided in Section 2.1(e)) be paid to the Company upon request by the Company or, if then held by the Company, shall be discharged from such trust.

    Section 10.7.  Securities Redeemed in Part.  

    Any Security which is to be redeemed only in part shall be surrendered at an office or agency of the Company designated for that purpose pursuant to Section 9.2 hereof (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or the Holder's attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of any authorized denomination as requested by such Holder in principal amount equal to and in exchange for the unredeemed portion of the Security so surrendered.

    Section 12.2.  Exercise of Conversion Right  

    (a) To exercise the conversion right with respect to a Physical Security, a Holder must (1) deliver a completed conversion notice, the form of which is provided in Exhibit C, to the Depositary stating that the Holder elects to convert such Physical Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted, (2) deliver duly signed completed conversion notice and the Physical Security duly endorsed or assigned to the Company or in blank, at the office of any Conversion Agent, (3) pay all Interest to which the Holder is not entitled, if any, pursuant to Section 2.1(e) and (4) pay any transfer taxes or other applicable taxes or duties, if required.

succeeding Interest Payment Date (except in the case of any Security whose Stated Maturity is prior to such Interest Payment Date) shall be accompanied by payment by such Holder in immediately available funds to the Company of an amount equal to the Interest to be received on such Interest Payment Date on principal amount of Securities being surrendered for conversion. To the extent provided in Section 2.1, Securities which have been called for redemption by the Company in a notice of redemption pursuant to Section 10.4, and are converted prior to redemption, shall not require such concurrent payment to the Company surrender for conversion, and if converted during time period set forth in the preceding sentence, the Holders of such converted Securities shall be entitled to receive (and retain) any accrued interest on the principal amount of such surrendered Securities, if any.

    (d) Securities shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Securities as Holders 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 shares of Common Stock at such time.

    (e) In the case of any Security which is converted in part only, or a Holder converts less than the principal amount it owns at such time, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Security or Securities of authorized denominations in principal amount equal to the unconverted portion of the principal amount of such Securities.

    (f)  As promptly as practicable on or after the Conversion Date, the Company shall cause to be issued and delivered to such Conversion Agent a certificate or certificates for the number of full shares of Common Stock issuable upon conversion of such Securities, together with payment in lieu of any fraction of a share as provided in Section 12.3 hereof. The Company hereby initially appoints The Bank of New York as the Conversion Agent.

    (g) Securities shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Securities as Holders 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 shares of Common Stock at such time.

    (h) A Security in respect of which a Holder has delivered a Change of Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if such notice of exercise is withdrawn in accordance with Section 11.3.

    Section 12.3.  Fractions of Shares.  

    No fractional shares of Common Stock shall be issued upon conversion of any Security or Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock which shall be issued upon conversion thereof shall be computed on the basis of the principal amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional shares of Common Stock which would otherwise be issued upon conversion of any Security or Securities (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction (calculated to the nearest one-100th of a share) in an amount equal to the same fraction of the Trading Price of the shares of Common Stock as of the Trading Day preceding the Conversion Date.

D–45

    Section 12.4.  Adjustment of Conversion Price.  

    The Conversion Price shall be subject to adjustment, calculated in good faith by the Company, from time to time as follows:

    (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Price in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction:

        (1) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the Conversion Record Date fixed for such determination; and

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

    Such reduction shall become effective immediately after the opening of business on the day following the Conversion Record Date. If any dividend or distribution of the type described in this Section 12.4(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

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

    (c) In case the Company shall issue rights or warrants (other than any rights or warrants issued pursuant to a rights plan (commonly referred to as a "poison pill" plan) referred to in Section 12.4(d)) to all holders of its outstanding shares of Common Stock entitling them to subscribe for or purchase shares of Common Stock (or securities convertible into shares of Common Stock) at a price per share (or having a conversion price per share) less than the Current Market Price on the Conversion Record Date fixed for the determination of stockholders entitled to receive such rights or warrants, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the date after such Conversion Record Date by a fraction:

        (1) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the Conversion Record Date, plus the number of shares which the aggregate offering price of the total number of shares so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered) would purchase at such Current Market Price; and

        (2) the denominator of which shall be the number of shares of Common Stock outstanding on the close of business on the Conversion Record Date, plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible securities so offered are convertible).

    Such adjustment shall become effective immediately after the opening of business on the day following the Conversion Record Date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock (or securities convertible into Common Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such

D–46

rights or warrants, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value of such consideration if other than cash, to be determined by the Board of Directors.

    (d) (i) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of Capital Stock of the Company (other than any dividends or distributions to which Section 12.4(a) applies) or evidences of its indebtedness, cash or other assets, including securities, but excluding (1) any rights or warrants referred to in Section 12.4(c), (2) dividends or distributions of stock, securities or other property or assets (including cash) in connection with a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.11 applies and (3) dividends and distributions paid exclusively in cash (such Capital Stock, evidence of its indebtedness, cash, other assets or securities being distributed hereinafter in this Section 12.4(d) called the "distributed assets"), then, in each such case, subject to clause (ii) of this Section 12.4(d), the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Conversion Record Date with respect to such distribution by a fraction:

        (1) the numerator of which shall be the Current Market Price on such date, less the Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) on such date of the portion of the distributed assets so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Conversion Record Date); and

        (2) the denominator of which shall be such Current Market Price.

    Such reduction shall become effective immediately prior to the opening of business on the day following the Conversion Record Date. However, in the event that the then Fair Market Value (as so determined) of the portion of the distributed assets so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Conversion Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of a Security (or any portion thereof) the amount of distributed assets such Holder would have received had such Holder converted such Security (or portion thereof) immediately prior to such Conversion Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

    (ii) If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 12.4(d) by reference to the actual or when issued trading market for any distributed assets comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the "Reference Period") used in computing the Current Market Price to the extent possible, unless the Board of Directors in a Board Resolution determines in good faith that determining the Fair Market Value during the Reference Period would not be in the best interest of the Holders.

    (iii) Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company's Capital Stock (either initially or

D–47

under certain circumstances), which rights or warrants, until the occurrence of a specified event or events specified in such rights or warrants or related instruments or agreements governing the same (a "Trigger Event"):

        (1) are deemed to be transferred with such shares of Common Stock;

        (2) are not exercisable; and

        (3) are also issued in respect of future issuances of Common Stock;

shall be deemed not to have been distributed for purposes of this Section 12.4(d) (and no adjustment to the Conversion Price under this Section 12.4(d) will be required) until the occurrence of the earliest Trigger Event; provided that (1) if such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different distributed assets, evidences of indebtedness or other assets or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and the Conversion Record Date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof); and (2) in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Price under this Section 12.4(d):

        (1) in the case of any such rights or warrants which shall all have been redeemed or purchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or purchase to give effect to such distribution or Trigger Event, as applicable, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or purchase; and

        (2) in the case of such rights or warrants which shall have expired or been terminated without exercise, the Conversion Price shall be readjusted as if such rights and warrants had never been issued.

    For purposes of this Section 12.4(d) and Sections 12.4(a), 12.4(b) and 12.4(c), any dividend or distribution to which this Section 12.4(d) is applicable that also includes shares of Common Stock, a subdivision or combination of Common Stock to which Section 12.4(b) applies, or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 12.4(c) applies (or any combination thereof), shall be deemed instead to be:

    (A) a dividend or distribution of the evidences of indebtedness, assets, shares of Capital Stock, rights or warrants, other than such shares of Common Stock, such subdivision or combination or such rights or warrants to which Sections 12.4(a), 12.4(b) and 12.4(c) apply, respectively (and any Conversion Price reduction required by this Section 12.4(d) with respect to such dividend or distribution shall then be made), immediately followed by

    (B) a dividend or distribution of such shares of Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion Price reduction required by Sections 12.4(a), 12.4(b) and 12.4(c) with respect to such dividend or distribution shall then be made), except:

      (I)
      the Conversion Record Date of such dividend or distribution shall be substituted as (x) 'the date fixed for the determination of stockholders entitled to receive such dividend or other distribution", "Conversion Record Date fixed for such determinations" and "Conversion Record Date" within the meaning of Section 12.4(a), (y) 'the day upon which such subdivision becomes effective" and "the day upon which such combination

D–48

        becomes effective" within the meaning of Section 12.4(b), and (z) as "the date fixed for the determination of stockholders entitled to receive such rights or warrants", "the Conversion Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants" and such "Conversion Record Date" within the meaning of Section 12.4(c); and

      (II)
      any shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the date fixed for such determination" within the meaning of Section 12.4(a) and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution.

    (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is distributed upon a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.11 applies or as part of a distribution referred to in Section 12.4(d)), in an aggregate amount that, combined together with:

        (1) the aggregate amount of any other such distributions to all holders of Common Stock made exclusively in cash within the 12 months preceding the date of payment of such distribution, and in respect of which no adjustment pursuant to this Section 12.4(e) has been made; and

        (2) the aggregate of any cash plus the Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) of consideration payable in respect of any tender offer by the Company or any of its subsidiaries for all or any portion of the Common Stock concluded within the 12 months preceding the date of such distribution, and in respect of which no adjustment pursuant to Section 12.4(f) has been made;

exceeds 10% of the product of the Current Market Price on the Conversion Record Date with respect to such distribution multiplied by the number of shares of Common Stock outstanding on such date, then and in each such case, immediately after the close of business on such date, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on such Conversion Record Date by a fraction:

        (1) the numerator of which shall be equal to the Current Market Price on the Conversion Record Date less an amount equal to the quotient of (x) the excess of such combined amount over such 10% and (y) the number of shares of Common Stock outstanding on the Conversion Record Date, and

        (2) the denominator of which shall be equal to the Current Market Price on such date.

    However, in the event that the then Fair Market Value (as so determined) of the portion of the securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Conversion Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of a Security (or any portion thereof) the amount of cash such Holder would have received had such Holder converted such Security (or portion thereof) immediately prior to such Conversion Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

    (f)  In case a tender offer made by the Company or any of its subsidiaries 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) of an aggregate consideration having a Fair Market

D–49

Value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) that combined together with:

        (1) the aggregate of the cash plus the Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution), as of the expiration of such tender offer, of consideration payable in respect of any other tender offers, by the Company or any of its subsidiaries for all or any portion of the Common Stock expiring within the 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this Section 12.4(f) has been made; and

        (2) the aggregate amount of any distributions to all holders of the Company's Common Stock made exclusively in cash within 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to Section 12.4(e) has been made,

exceeds 10% of the product of the Current Market Price as of the last time (the "Expiration Time") tenders could have been made pursuant to such tender offer (as it may be amended) multiplied by the number of shares of Common Stock outstanding (including any tendered shares) on 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 Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to close of business on the date of the Expiration Time by a fraction:

        (1) the numerator of which shall be the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time; and

        (2) the denominator shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender offer) 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") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time

    Such reduction (if any) shall become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender offer had not been made. If the application of this Section 12.4(f) to any tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 12.4(f).

    (g) For purposes of this Section 12.4, the following terms shall have the meanings indicated:

        (1) 'Current Market Price" of shall mean the average of the daily Trading Prices per share of Common Stock (or such other security as specified herein) for the ten consecutive Trading Days immediately prior to the date in question; provided, however, that if:

          (i)  the "ex" date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(a), (b), (c), (d), (e) or (f) occurs during such ten consecutive Trading Days, the Trading Price for each Trading Day prior to the "ex" date for such other event shall be adjusted by multiplying such Trading Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event;

D–50

          (ii) the "ex" date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(a), (b), (c), (d), (e) or (f) occurs on or after the "ex" date for the issuance or distribution requiring such computation and prior to the day in question, the Trading Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Trading Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event; and

          (iii) the "ex" date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (i) or (ii) of this proviso, the Trading Price for each Trading Day on or after such "ex" date shall be adjusted by adding thereto the amount of any cash and the Fair Market Value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 12.4(d) or (f), whose determination shall be conclusive and set forth in a Board Resolution) of the evidences of indebtedness, shares of Capital Stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such "ex" date.

    For purposes of any computation under Section 12.4(f), the Current Market Price of the Common Stock on any date shall be deemed to be the average of the daily Trading Prices per share of Common Stock for such day and the next two succeeding Trading Days; provided, however, that if the "ex" date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(a), (b), (c), (d), (e) or (f) occurs on or after the Expiration Time for the tender or exchange offer requiring such computation and prior to the day in question, the Trading Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Trading Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term "ex" date, when used:

        (I) with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Trading Price was obtained without the right to receive such issuance or distribution;

        (II) with respect to any subdivision or combination of shares of Common Stock, means the first date on which the shares of Common Stock trade regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective; and

        (III) with respect to any tender or exchange offer, means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer.

    Notwithstanding the foregoing, whenever successive adjustments to the Conversion Price are called for pursuant to this Section 12.4, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 12.4 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

        (1) "Fair Market Value" shall mean, if there is a current market for the asset, debt or transaction in question, the amount that a willing buyer would pay a willing seller in an arm's length transaction or, in the absence of a current market for such asset, debt or transaction, the amount determined in good faith by the Board of Directors that represents its determination of the fair market value of the asset.

        (2) "Conversion Record Date" shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

D–51

    The Company may make such reductions in the Conversion Price, in addition to those required by Sections 12.4(a), (b), (c), (d), (e) or (f), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any even treated as such for income tax purposes or otherwise.

    (h) No adjustment need be made for (i) a transaction referred to in Sections 12.4 or 12.11 if Holders participate in the transaction without conversion on a basis and with notice that the Board of Directors determines to be fair and appropriate in light of the basis and notice on which holders of shares of Common Stock participate in the transaction; (ii) the issuance and distribution of rights to purchase shares of Common Stock pursuant to (A) a Company plan for reinvestment of dividends or interest, (B) a change in the par value or no par value of the shares of Common Stock or (C) to the extent the Securities become convertible pursuant to this Article 12 in whole or in part into cash, with respect to such cash after such cash is distributed to the Holders in satisfaction of such conversion right.

    (i)  To the extent permitted by applicable law, the Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 days and the reduction is irrevocable during the period and the Board of Directors determines in good faith that such reduction would be in the best interests of the Holders, which determination shall be conclusive and set forth in a Board Resolution. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to the Trustee and the Conversion Agent and each Holder at the address of such Holder as it appears in the Register a notice of the reduction at least 15 days prior to the date the reduced Conversion Price takes effect, and such notice shall state the reduced Conversion Price and the period during which it will be in effect.

    (j)  No adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this Section 12.4(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 12 shall be made by the Company in good faith and shall be made to the nearest cent or to the nearest one hundredth of a share, as applicable. No adjustment need be made for a change in the par value or no par value of the Common Stock.

    (k) No adjustment in Conversion Price shall be required if the Fair Market Value of any assets, debt securities or rights, warrants or options to purchase the securities of the Company, including but not limited to Common Stock, in each case applicable to each share of Common Stock are distributed to the Company's stockholders and such Fair Market Value either equals or exceeds the Current Market Price or such Current Market Price exceeds the such Fair Market Price Value by an amount not exceeding $1.00; provided, however, that any adjustments which by reason of this Section 12.4(k) are not required to be made shall be distributed upon conversion of any Security in an amount of assets, securities or rights, warrants or options comprising the distribution that a Holder would have received if such Holder had converted such Security immediately prior to the Conversion Record Date.

    (l)  In any case in which this Section 12.4 provides that an adjustment shall become effective immediately after a Conversion Record Date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any security converted after such Conversion Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 12.3.

    (m) For purposes of this Section 12.4, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares

D–52

issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

    (n) If the distribution date for the rights provided in the Company's rights agreement, if any, occurs prior to the date a Security is converted, the Holder of the Security who converts such Security after the distribution date is not entitled to receive the rights that would otherwise be attached (but for the date of conversion) to the shares of Common Stock received upon such conversion; provided, however, that an adjustment shall be made to the Conversion Price pursuant to clause 12.4(b) as if the rights were being distributed to the common stockholders of the Company immediately prior to such conversion. If such an adjustment is made and the rights are later redeemed, invalidated or terminated, then a corresponding reversing adjustment shall be made to the Conversion Price, on an equitable basis, to take account of such event.

    (o) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of Capital Stock of a subsidiary of the Company, then the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Conversion Record Date with respect to such distribution by a fraction:

        (1) the numerator of which shall be the Current Market Price of the shares of Capital Stock of such subsidiary (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution), measured from the date of such distribution; and

        (2) the denominator of which shall be the Current Market Price of the Company's common stock, measured from the date of such distribution.

    Section 12.5.  Notice of Adjustments of Conversion Price.  

    Whenever the Conversion Price is adjusted as herein provided (other than in the case of an adjustment pursuant to the second paragraph of Section 12.4(i) for which the notice required by such paragraph has been provided), the Company shall promptly file with the Trustee and any Conversion Agent other than the Trustee an Officers' Certificate setting forth the adjusted Conversion Price and showing in reasonable detail the facts upon which such adjustment is based. Promptly after delivery of such Officers' Certificate, the Company shall prepare a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price and the date on which each adjustment becomes effective, and shall mail such notice to each Holder at the address of such Holder pursuant to Section 14.2 within 20 days prior to the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

    Section 12.6.  Notice Prior to Certain Actions.  

    In case at any time after the date hereof:

        (1) the Company shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash out of its capital surplus or its consolidated retained earnings;

        (2) the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any shares of Capital Stock of any class (or of securities convertible into shares of Capital Stock of any class) or of any other rights;

        (3) there shall occur any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, a change in par value, a change from par value to no par value or a change from no par value to par value), or any merger, consolidation, statutory share exchange or combination to which the Company is a party and for

D–53

    which approval of any shareholders of the Company is required, or the sale, transfer or conveyance of all or substantially all of the assets of the Company; or

        (4) there shall occur the voluntary or involuntary dissolution, liquidation or winding up of the Company;

the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of securities pursuant to Section 9.2, and shall cause to be provided to the Trustee and all Holders in accordance with Section 14.2, at least 20 days (or 10 days in any case specified in clause (1) or (2) above) prior to the applicable record or effective date hereinafter specified, a notice stating:

        (A) the date on which a record is to be taken for the purpose of such dividend, distribution, rights or warrants, or, if a record is not to be taken, the date as of which the holders of shares of Common Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined; or

        (B) the date on which such reclassification, merger, consolidation, statutory share exchange, combination, sale, transfer, conveyance, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of shares 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, merger, consolidation, statutory share exchange, sale, transfer, dissolution, liquidation or winding up.

    Neither the failure to give such notice nor any defect therein shall affect the legality or validity of the proceedings or actions described in clauses (1) through (4) of this Section 12.6.

    Section 12.7.  Company to Reserve Common Stock.  The Company 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 the Securities, the full number of shares of fully paid and nonassessable Common Stock then issuable upon the conversion of all Outstanding Securities.

    Section 12.8.  Common Stock to be Fully Paid and Nonassessable.  

    The Company covenants that all Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and nonassessable and, except as provided in Section 12.9, the Company will pay all taxes, liens and charges with respect to the issue thereof.

    Section 12.9.  Taxes on Conversions.  

    Except as provided in the next sentence, the Company will pay any and all taxes (other than taxes on income) and duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant to Article 12. A Holder delivering a Security for conversion shall be liable for and will be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless the Person requesting such issue has paid to the Company the amount of any such tax or duty, or has established to the satisfaction of the Company that such tax or duty has been paid.

    Section 12.10.  Cancellation of Converted Securities.  

    All Securities delivered for conversion shall be delivered to the Trustee to be canceled by or at the direction of the Trustee.

D–54

    Section 12.11.  Effect of Reclassification, Consolidation, Merger or Sale.  

    If any of following events occur:

        (1) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), as a result of which holders of Common Stock shall be entitled to receive Capital Stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock;

        (2) any merger, consolidation, statutory share exchange or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock; or

        (3) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock,

then (A) the Company or the successor or purchasing corporation, as applicable, shall execute with the Trustee a supplemental indenture (which shall comply with this Indenture and the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that such security shall be convertible into the kind and amount of shares of capital stock and other securities or property or assets (including cash) which such Holder would have been entitled to receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such Securities been converted into Common Stock immediately prior to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance is not the same for each shares of Common Stock in respect of which such rights of election shall not have been exercised ("Non-Electing Share"), then for the purposes of this Section 12.11 the kind and amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance for 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 which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 12. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as applicable, in such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the Purchase rights set forth in Article 11.

    The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the Register, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

D–55

    The above provisions of this Section shall apply to successive or series of related reclassifications, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances.

    If this Section 12.11 applies to any event or occurrence, Section 12.4 shall not apply.

    Section 12.12.  Responsibility of Trustee for Conversion Provisions.  

    The Trustee, subject to the provisions of Section 5.1, and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine whether any facts exist which may require any adjustment of the Conversion Price, or with respect to the nature or intent of any such adjustments when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. Neither the Trustee, subject to the provisions of Section 5.1, nor any Conversion Agent shall be accountable with respect to the validity or value (of the kind or amount) of any Common Stock or of any other securities or property, which may at any time be issued or delivered upon the conversion of any Security; and it or they do not make any representation with respect thereto. Neither the Trustee, subject to the provisions of Section 5.1, nor any Conversion Agent shall be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of stock or share certificates or other securities or property upon the surrender of any Security for the purpose of conversion; and the Trustee, subject to the provisions of Section 5.1, and any Conversion Agent shall not be responsible or liable for any failure of the Company to comply with any of the covenants of the Company contained in this Article.


ARTICLE 13

SUBORDINATION

    Section 13.1.  Subordination to Senior Debt.  

    The Company covenants and agrees, and each Holder of Securities, by such Holder's acceptance thereof, is deemed to covenant and agree, that the Indebtedness represented by the Securities and the payment of the Principal of and Interest on each and all of the Securities is hereby expressly subordinated and junior, to the extent and in the manner set forth and as set forth in this Section 13.1, in right of payment to the prior payment in full of all Senior Debt.

    (a) In the event of any distribution of assets of the Company upon any dissolution, winding up, liquidation or reorganization of the Company, whether in bankruptcy, insolvency, reorganization or receivership proceedings or upon an assignment for the benefit of creditors or any other marshalling of the assets and liabilities of the Company or otherwise, the holders of all Senior Debt shall first be entitled to receive payment of the full amount due thereon in respect of all such Senior Debt and all other amounts due or provision shall be made for such amount in cash, or other payments satisfactory to the holders of Senior Debt, before the Holders of any of the Securities are entitled to receive any payment or distribution of any character, whether in cash, securities or other property, on account of the Principal of or Interest on the Indebtedness evidenced by the Securities, except that the Company may, but shall not be required to, make payments on the Securities in Permitted Junior Securities.

    (b) In the event of any acceleration of Maturity of the Securities because of the occurrence and confirmation of an Event of Default, unless the full amount due in respect of all Senior Debt is paid in cash or other form of payment satisfactory to the holders of Senior Debt, no payment shall be made by the Company with respect to the Principal of or Interest on the Securities or to acquire any of the Securities (including any redemption or cash Purchase pursuant to the exercise of the Purchase Right), except that the Company may, but shall not be required to, make payments on the Securities in Permitted Junior Securities, and the Company shall give prompt written notice of such acceleration to such holders of Senior Debt.

D–56

    (c) In the event of and during the continuance of any default in payment of the principal of or premium, if any, or interest on, rent or other payment obligation in respect of, any Senior Debt, unless all such payments due in respect of such Senior Debt have been paid in full in cash or other payments satisfactory to the holders of Senior Debt, no payment shall be made by the Company with respect to the Principal of or Interest on the Securities or to acquire any of the Securities (including any redemption or cash purchase pursuant to the exercise of the Purchase Right), except that the Company may, but shall not be required to, make payments on the Securities in Permitted Junior Securities. The Company shall give prompt written notice to the Trustee of any default under any Senior Debt or under any agreement pursuant to which Senior Debt may have been issued.

    (d) During the continuance of any event of default with respect to any Designated Senior Debt, as such event of default is defined under any such Designated Senior Debt or in any agreement pursuant to which any Designated Senior Debt has been issued (other than a default in payment of the principal of or premium, if any, or interest on, rent or other payment obligation in respect of any Designated Senior Debt), permitting the holder or holders of such Designated Senior Debt to accelerate the maturity thereof (or, in the case of any lease, permitting the landlord either to terminate the lease or to require the Company to make an irrevocable offer to terminate the lease following an event of default thereunder), no payment shall be made by the Company, directly or indirectly, with respect to Principal of or Interest on the Securities, other than payments in Permitted Junior Securities, for 179 days following notice in writing (a "Payment Blockage Notice") to the Company, from any holder or holders of such Designated Senior Debt or their representative or representatives or the trustee or trustees under any indenture or under which any instrument evidencing any such Designated Senior Debt may have been issued, that such an event of default has occurred and is continuing, unless such event of default has been cured or waived or such Designated Senior Debt has been paid in full; provided, however, if the maturity of such Designated Senior Debt is accelerated (or, in the case of any lease, permitting the landlord either to terminate the lease or to require us to make an irrevocable offer to terminate the lease following an event of default thereunder), no payment may be made on the Securities, other than payments in Permitted Junior Securities, until such Designated Senior Debt has been paid in full in cash or other payment satisfactory to the holders of such Designated Senior Debt or such acceleration has been cured or waived.

    For purposes of this Section 13.1(d), such Payment Blockage Notice shall be deemed to include notice of all other events of default under such indenture or instrument which are continuing at the time of the event of default specified in such Payment Blockage Notice. The provisions of this Section 13.1(d) shall apply only to one such Payment Blockage Notice given in any period of 365 days with respect to any issue of Designated Senior Debt, and only one such Payment Blockage Notice may be delivered in any such period, and no such continuing event of default that existed or was continuing on the date of delivery of any Payment Blockage Notice shall be, or shall be made, the basis for a subsequent Payment Blockage Notice.

    (e) In the event that, notwithstanding the foregoing provisions of Sections 13.1(a), 13.1(b), 13.1(c) and 13.1(d), any payment on account of Principal or Interest on the Securities shall be made by or on behalf of the Company and received by the Trustee, by any Holder or by any Paying Agent (or, if the Company is acting as its own Paying Agent, money for any such payment shall be segregated and held in trust):

        (1) after the occurrence of an event specified in Section 13.1(a) or 13.1(b), then, unless all Senior Debt is paid in full in cash, or provision shall be made therefore;

        (2) after the happening of an event of default of the type specified in Section 13.1(c) above, then, unless the amount of such Senior Debt then due shall have been paid in full, or provision made therefor or such event of default shall have been cured or waived; or

D–57

        (3) after the happening of an event of default of the type specified in Section 13.1(d) above and delivery of a Payment Blockage Notice, then, unless such event of default shall have been cured or waived or the 179-day period specified in Section 13.1(d) shall have expired,

such payment (subject, in each case, to the provisions of Section 13.7 hereof) shall be held in trust for the benefit of, and shall be immediately paid over to, the holders of Designated Senior Debt (unless an event described in Section 13.1(a), (b) or (c) has occurred, in which case the payment shall be held in trust for the benefit of, and shall be immediately paid over to all holders of Senior Debt) or their representative or representatives or the trustee or trustees under any indenture under which any instruments evidencing any of the Designated Senior Debt or Senior Debt, as the case may be, may have been issued, as their interests may appear.

    Section 13.2.  Subrogation.  

    Subject to the payment in full of all Senior Debt to which the Indebtedness evidenced by the Securities is in the circumstances subordinated as provided in Section 13.1 hereof, the Holders of the Securities shall be subrogated to the rights of the holders of such Senior Debt to receive payments or distributions of cash, property or securities of the Company applicable to such Senior Debt until all amounts owing on the Securities shall be paid in full, and, as between the Company, its creditors other than holders of such Senior Debt, and the Holders of the Securities, no such payment or distribution made to the holders of Senior Debt by virtue of this Article which otherwise would have been made to the holders of the Securities shall be deemed to be a payment by the Company on account of such Senior Debt, provided that the provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of Senior Debt, on the other hand.

    Section 13.3.  Obligation of the Company is Absolute and Unconditional.  

    Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Debt, and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the Principal of and Interest on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Securities and creditors of the Company other than the holders of Senior Debt, nor shall anything contained herein or therein prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Debt in respect of cash, property or securities of the Company received upon the exercise of any such remedy.

    Section 13.4.  Maturity of or Default on Senior Debt.  

    Upon the maturity of any Senior Debt by lapse of time, acceleration or otherwise, all principal of or premium, if any, or interest on, or other payment obligations in respect of all such matured Senior Debt shall first be paid in full, or such payment shall have been duly provided for, before any payment on account of Principal or Interest is made upon the Securities, except that the Company may make payments on the Securities in Permitted Junior Securities.

    Section 13.5.  Payments on Securities Permitted.  

    Except as expressly provided in this Article, nothing contained in this Article shall affect the obligation of the Company to make, or prevent the Company from making, payments of the Principal of or Interest on the Securities in accordance with the provisions hereof and thereof, or shall prevent the Trustee or any Paying Agent from applying any moneys deposited with it hereunder to the payment of the Principal of or Interest on the Securities.

D–58

    Section 13.6.  Effectuation of Subordination by Trustee.  

    Each Holder of Securities, by such Holder's acceptance thereof, authorizes and directs the Trustee on such Holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee such Holder's attorney-in-fact for any and all such purposes.

    Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee and the Holders of the Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which any such dissolution, winding up, liquidation or reorganization proceeding affecting the affairs of the Company is pending or upon a certificate of the trustee in bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee or agent or other Person making any payment or distribution, delivered to the Trustee or to the Holders of the Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, and as to other facts pertinent to the right of such Persons under this Article, and if such evidence is not furnished, the Trustee may defer any payment to such Persons pending judicial determination as to the right of such Persons to receive such payment.

    Section 13.7.  Knowledge of Trustee.  

    Notwithstanding the provision of this Article or any other provisions of this Indenture, the Trustee shall not be charged with knowledge of the existence of any Senior Debt, of any default in payment of principal of, premium, if any, or interest on, or other payment obligation in respect of any Senior Debt, or of any facts which would prohibit the making of any payment of moneys to or by the Trustee, or the taking of any other action by the Trustee, unless a Responsible Officer of the Trustee having responsibility for the administration of the trust established by this Indenture shall have received written notice thereof from the Company, any Holder of Securities, any Paying or Conversion Agent of the Company or the holder or representative of any class of Senior Debt, and, prior to the receipt of any such written notice, the Trustee shall be entitled in all respects to assume that no such default or facts exist; provided, however, that unless on the third Business Day prior to the date upon which by the terms hereof any such moneys may become payable for any purpose the Trustee shall have received the notice provided for in this Section 13.7, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such moneys and apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such date.

    Section 13.8.  Trustee's Relation to Senior Debt.  

    The Trustee shall be entitled to all the rights set forth in this Article with respect to any Senior Debt at the time held by it, to the same extent as any other holder of Senior Debt and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.

    Nothing contained in this Article shall apply to claims of or payments to the Trustee under or pursuant to Section 5.8 hereof.

    With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and the Trustee shall not be liable to any holder of Senior Debt if it shall pay over or deliver to Holders, the Company or any other Person moneys or assets to which any holder of Senior Debt shall be entitled by virtue of this Article or otherwise.

D–59

    Section 13.9.  Rights of Holders of Senior Debt Not Impaired.  

    No right of any present or future holder of any Senior Debt to enforce the subordination herein shall at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with.

    Section 13.10.  Modification of Terms of Senior Debt.  

    Any renewal or extension of the time of payment of any Senior Debt or the exercise by the holders of Senior Debt of any of their rights under any instrument creating or evidencing Senior Debt, including without limitation the waiver of default thereunder, may be made or done all without notice to or assent from the Holders of the Securities or the Trustee.

    No compromise, alteration, amendment, modification, extension, renewal or other change of, or waiver, consent or other action in respect of, any liability or obligation under or in respect of, or of any of the terms, covenants or conditions of any indenture or other instrument under which any Senior Debt is outstanding or of such Senior Debt, whether or not such release is in accordance with the provisions or any applicable document, shall in any way alter or affect any of the provisions of this Article or of the Securities relating to the subordination thereof.

    Section 13.11.  Certain Conversions Not Deemed Payment.  

    (a) For the purposes of this Article 13 only:

        (1) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article 12 hereof shall not be deemed to constitute a payment or distribution on account of the Principal or Interest on Securities or on account of the purchase or other acquisition of Securities, and

        (2) the payment, issuance or delivery of cash (except in satisfaction of fractional shares pursuant to Section 12.3 hereof), property or securities (other than junior securities) upon conversion of a Security shall be deemed to constitute payment on account of the Principal of or Interest on such Security.

    (b) For the purposes of this Section 13.11, the term "junior securities" means:

        (1) shares of any Common Stock of the Company; or

        (2) other securities of the Company that are subordinated in right of payment to all Senior Debt that may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent that, the Securities are so subordinated as provided in this Article.

    (c) Nothing contained in this Article 13 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors (other than holders of Senior Debt) and the Holders of Securities, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article 12 hereof.

    Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, unless such officer knows, or in the exercise of reasonable care should know, that the Opinion of Counsel with respect to the matters upon which such certificate or opinion is based is erroneous. Any such Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or representations with respect to such matters are erroneous.

    Section 14.6.  Statements Required in Certificate or Opinion.  

    Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include:

        (1) a statement that each individual signing such certificate or opinion on behalf of the Company, has read such covenant or condition and the definitions herein relating thereto;

        (2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

    THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

    Section 14.12.  Counterparts.  

    This instrument may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original but all such counterparts shall together constitute but one and the same instrument.

    Section 14.13.  Legal Holidays.  

    In any case where any Interest Payment Date, Redemption Date, Change of Control Purchase Date or Stated Maturity of any Security or the last day on which a Holder of a Security has a right to convert such Security shall not be a Business Day at any Place of Payment or Place of Conversion, then (notwithstanding any other provision of this Indenture or of the Securities) payment of Principal on or Interest on or conversion of the Securities, need not be made at such Place of Payment or Place of Conversion on such day, but may be made on the next succeeding Business Day at such Place of Payment or Place of Conversion with the same force and effect as if made on the Interest Payment Date, Redemption Date, Change of Control Purchase Date or at the Stated Maturity or on such last day for conversion; provided, however, that in the case that payment is made on such succeeding Business Day, no Interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, Change of Control Purchase Date or Stated Maturity, as applicable.

    Section 14.14.  Recourse Against Others.  

    No recourse for the payment of the Principal of or Interest on any Securities, or for any claim based thereon or otherwise in respect thereof, shall be had against any incorporator, shareholder, officer or director or manager, as such, past, present or future, of the Company of any successor entity to either the Company, 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 thereof and as part of the consideration for the issue thereof, expressly waived and released.

INTERMUNE, INC.

53/4% Convertible Subordinated Note due 2006

    1.  Indenture; Securities

    This Security is one of a duly authorized series of the 53/4% Convertible Subordinated Notes due 2006 (the "Securities") of InterMune, Inc., a Delaware corporation (including any successor corporation under the Indenture hereinafter referred to, the "Company"), issued under an Indenture, dated as of July 5, 2001 (the "Indenture"), between the Company and The Bank of New York, as trustee (the "Trustee"). The terms of the Security include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended ("TIA"). This Security is subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the Indenture shall control. Capitalized terms used but not defined herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

    2.  Principal and Interest.

    The Company promises to pay Interest on the principal amount of the Securities at the Interest Rate from the date of issuance until repayment in full at Stated Maturity, redemption or purchase. The Company will pay Interest on this Security semiannually in arrears on July 15 and January 15 of each year (each, an "Interest Payment Date"), commencing January 15, 2002.

    The Securities shall bear Interest from July 5, 2001 until the Principal amount thereof is paid or made available for payment, or until such date on which the Securities are converted, redeemed or purchased as provided herein, (i) prior to the occurrence of a Reset Transaction, at a rate of 53/4% per annum, and (ii) following the occurrence of a Reset Transaction, at the Adjusted Interest Rate related to such Reset Transaction to, but not including, the effective date of any succeeding Reset Transaction. Interest shall be payable semiannually in arrears on each Interest Payment Date.

    Interest on the Securities shall be computed (i) for any full semi-annual period for which a particular Interest Rate is applicable, on the basis of a 360-day year of twelve 30-day months and (ii) for any period for which a particular Interest Rate is applicable for less than a full semiannual period for which Interest is calculated, on the basis of a 30-day month and, for such periods of less than a month, the actual number of days elapsed over a 30-day month. For purposes of determining the Interest Rate, the Trustee may assume that a Reset Transaction has not occurred unless the Trustee has received an Officers' Certificate stating that a Reset Transaction has occurred and specifying the Adjusted Interest Rate then in effect.

    Interest shall be due and payable on the Securities as follows:

        (1) A registered Holder of any Security as of the close of business on a Regular Record Date shall be entitled (except as otherwise indicated in Section 2.1(e) of the Indenture) to receive and shall receive, as the registered Holder as of such Regular Record Date, Interest on such Security on the corresponding Interest Payment (other than any Security whose Stated Maturity is prior to such Interest Payment Date).

        (2) In the event that a Security becomes subject to redemption pursuant to Article 10 of the Indenture and the Redemption Date occurs after a Regular Record Date, the Person whose Securities become subject to redemption (and only such Person rather than the Holder as of such Regular Record Date) shall be entitled to receive and shall receive accrued and unpaid Interest from the preceding Interest Payment Date (or such earlier date on which Interest was last paid) to

4

    but not including the Redemption Date on such Security, even if such person is not the Holder of such Security.

        (3) In the event that a Security becomes subject to purchase pursuant to Article 11 of the Indenture, a Holder of any Security who exercises a purchase right with respect to such Security shall be entitled to receive and shall receive Interest to but not including the purchase date for such Security, which amount shall be included in the purchase price thereof.

        (4) In the event that a Security is converted pursuant to Article 12 of the Indenture, the Holder who converts such Security on any date other than an Interest Payment Date shall not be entitled to accrued and unpaid Interest from the preceding Interest Payment Date until the Conversion Date, or otherwise, on such Security, such amounts being deemed to have been paid by receipt of shares of Common Stock in full rather than canceled, extinguished or forfeited; and, accordingly, a Holder which converts a Security after a Regular Record Date but prior to the corresponding Interest Payment Date will receive accrued and unpaid Interest for such period on such Interest Payment Date but will be required to remit to the Company an amount equal to that Interest at the time such Holder surrenders the Security for conversion, provided that such Holder will not be required to remit such Interest if, prior to conversion, the Company has called such Security for redemption and the Holder converts such Security prior to the applicable Redemption Date.

    If the Company fails to make a payment of Principal of or Interest on any Security when due and payable, it shall pay such Interest on such amounts (to the extent lawful), which shall be calculated using the applicable Interest Rate (such amounts, the "Defaulted Interest"). It may elect to pay such Defaulted Interest, plus any other Interest payable on it, to the Persons who are Holders on which the Interest is due on a subsequent special record date. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Security. The Company shall fix any such special record date and payment date for such payment. At least 15 days before any such special record date, the Company shall mail to Holders affected thereby a notice that states the special record date, the Interest Payment Date and amount to be paid.

    3.  Method of Payment.

    Interest on this Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such Interest. Principal of and Interest on, Global Securities will be payable, for the benefit of the holders of this Security, to the Depositary in immediately available funds.

    Principal on Physical Securities will be payable at the office or agency of the Company maintained for such purpose, initially the Corporate Trust Office of the Trustee. Interest on Physical Securities will be payable by (i) U.S. Dollar check drawn on a bank in The City of New York mailed to the address of the Person entitled thereto as such address shall appear in the Register, or (ii) upon application to the Registrar not later than the relevant Regular Record Date by a Holder of an aggregate Principal amount in excess of $5,000,000, wire transfer in immediately available funds.

    4.  Paying Agent and Registrar.

    Initially, The Bank of New York will act as Paying Agent and Registrar. The Company may change the Paying Agent or Registrar without notice to any Holder.

5

    5.  Optional Redemption

    At any time on or after July 15, 2004, except for Securities that it is required to purchase pursuant to Section 11.1 of the Indenture or required to convert pursuant to Section 12.1 of the Indenture, the Company may, at its option, redeem this Security in whole at any time or in part from time to time, on any date prior to the Stated Maturity of the Security, upon notice as set forth in Section 10.4 of the Indenture, at the Redemption Price (expressed in percentages of the principal amount) set forth below if, but only if, redeemed on a Redemption Date occurring during the 12-month period beginning on the dates indicated:

During the Twelve Months Commencing
   Redemption
Price
July 15, 2004   102.8750%
July 15, 2005   101.4375%

    If the Company exercises its option to redeem this Security pursuant, a Holder may nevertheless exercise its right to have this Security purchased pursuant to Section 11.1 of the Indenture, if applicable, and to convert such Securities pursuant to Article 12 of the Indenture, in each case, until the close of business two Business Days immediately preceding the Redemption Date.

    The Company shall pay any Interest to the Holder of this Security if called for redemption (including if it is converted into Common Stock after the date the notice of the redemption is mailed and prior to the Redemption Date) accrued but not paid to, but excluding, the Redemption Date pursuant to Section 2.1(e) of the Indenture; provided, however, that if the Redemption Date is an Interest Payment Date, the Company shall pay the Interest to the Holder of the Security at the close of business on such Interest Payment Date. If the Security is redeemed, then on and after the Redemption Date, Interest shall cease to accrue on Securities or portions of Securities called for redemption, unless the Company defaults in the payment of the Redemption Price.

    Securities in original denominations larger than $1,000 may be redeemed in part. If any Security selected for partial redemption is converted or elected to be purchased in part before termination of the conversion right with respect to the portion of the Security so selected, the converted or purchased portion of such Security shall be deemed to be the portion selected for redemption (provided, however, that the Holder of such Security so converted or purchased and deemed redeemed shall not be entitled to any additional interest payment as a result of such deemed redemption than such Holder would have otherwise been entitled to receive upon conversion or purchase of such Security). Securities which have been converted or purchased during a selection of Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection.

    The Company is required to furnish the notice of redemption to the Holders as provided in the Indenture.

    6.  Purchase Right Upon a Change of Control.

    If a Change in Control occurs, this Security, at the Holder's option, shall have the right, subject to the conditions and in accordance with the provisions of the Indenture, to require the Company to purchase this Security (or any portion of the principal amount hereof that is at least $1,000 or an integral multiple thereof, provided that the portion of the principal amount of this Security to be Outstanding after such purchase is at least equal to $1,000 or an integral multiple thereof) at the Change of Control Purchase Price, plus any accrued and unpaid Interest to, but excluding, the Change of Control Purchase Date; provided, however, that (i) installments of Interest on this Security if its Stated Maturity is prior to or on the Change of Control Purchase Date shall be payable to the Holders of this Security, or one or more Predecessor Securities, registered as such on the relevant Regular Record Date according to their terms and the provisions of Section 2.1 of the Indenture and (ii) no

6

Holder shall have a Purchase Right upon a Change of Control unless prior to any payment of the Change of Control Purchase Price on the Change of Control Purchase Date the Company shall have made any applicable change of control offers required by the Company's Senior Debt and has purchased all Senior Debt validly tendered for payment in connection with such change of control offers; provided, further that the Company may elect to satisfy its obligation with respect to the Holders' Purchase Right (in cash or Common Stock or a combination thereof) by delivering to the applicable Holders the number of shares of Common Stock equal to (i) the Change of Control Purchase Price divided (to the extent not paid in cash) by (ii) 95% of the average of the Trading Prices per share of Common Stock for the five consecutive Trading Days immediately preceding and including the third Trading Day prior to the Purchase Date.

    The Company is required to furnish a Change of Control Notice to the Holders as provided in the Indenture. To exercise a Purchase Right, a Holder must deliver to the Trustee a completed Change of Control Notice as provided in the Indenture.

    7.  Conversion Right.

    Subject to and upon compliance with the provisions of the Indenture, the Holder of Securities is entitled, at such Holder's option, at any time and from tine to time, to convert this Security (or any portion of the principal amount hereof which is $1,000 or an integral multiple thereof), at the principal amount thereof or of such portion, into duly authorized, fully paid and nonassessable shares of Common Stock of the Company at the Conversion Price in effect at the time of conversion.

    The conversion right shall expire at the close of business on the Stated Maturity. If this Security (or a portion thereof) is called for redemption, such conversion right in respect of the Security (or such portion thereof) so called, shall expire at the close of business on the second Business Day preceding the Redemption Date, unless the Company defaults in making the payment due upon redemption. In the case of a Change of Control for which the Holder exercises its Purchase Right with respect to the Security (or a portion thereof), such conversion right in respect of the Security (or portion thereof) shall expire at the close of business on the second Business Day immediately preceding the Change of Control Purchase Date. The Conversion Price shall be initially equal to $38.40 per share of Common Stock, which may be adjusted under certain circumstances as provided in the Indenture.

    To exercise the conversion right with respect to a Physical Security, a Holder must (1) deliver a completed conversion notice, the form of which is provided in Exhibit C, to the Depositary stating that the Holder elects to convert such Physical Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted, (2) deliver duly signed completed conversion notice and the Physical Security duly endorsed or assigned to the Company or in blank, at the office of any Conversion Agent, (3) pay all Interest to which the Holder is not entitled, if any, pursuant to Section 2.1(e) and (4) pay any transfer taxes or other applicable taxes or duties, if required. To convert interests in a Global Security, a Holder must deliver to DTC the appropriate instruction form for conversion pursuant to DTC's conversion program or must deliver instructions in accordance with Euroclear's or Clearstream's normal operating procedures after application has been made to make the underlying Common Stock eligible for trading on Euroclear or Clearstream, as applicable.

    To the extent provided in Section 2.1(e) of the Indenture, if this Security is surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date (except in the case of any Security whose Stated Maturity is prior to such Interest Payment Date) shall be accompanied by payment by such Holder in immediately available funds to the Company of an amount equal to the Interest to be received on such Interest Payment Date on principal amount of Securities being surrendered for conversion. To the extent provided in Section 2.1 of the Indenture, if this Security has been called for redemption by the Company in a notice of redemption pursuant to Section 10.4 of the Indenture and are converted prior

7

to redemption, shall not require such concurrent payment to the Company surrender for conversion, and if converted during time period set forth in the preceding sentence, the Holders of such converted Securities shall be entitled to receive (and retain) any accrued Interest on the Principal of the surrendered Security, if at all.

    Securities shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Securities as Holders 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 shares of Common Stock at such time.

    A Security in respect of which a Holder has delivered a Change of Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if such notice of exercise is withdrawn in accordance with Section 11.3 of the Indenture.

    No fractional shares of Common Stock will be issued upon conversion of any Securities. Instead of any fractional share of Common Stock which would otherwise be issued upon conversion of such Securities, the Company shall pay a cash adjustment as provided in the Indenture.

    Reference is made to the Indenture for other rights and obligations of the Holders of this Security with respect to their right to convert this Security or any portion hereof.

    8.  Subordination.

    The Indebtedness evidenced by this Security is, to the extent and in the manner provided in the Indenture, subordinated and subject in right of payment to the prior payment in full of all amounts then due on all existing and future Senior Debt of the Company, and this Security is issued subject to such provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on such Holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee such Holder's attorney-in-fact for any and all such purposes.

    9.  No Sinking Fund.

    The Securities are not subject to a sinking fund.

    10.  Absolute Obligation.

    No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company under the Indenture and this Security which is absolute and unconditional, to pay the Principal of or Interest on this Security at the place and time and in the coin or currency herein prescribed.

    11.  Denominations; Transfer; Exchange.

    The Securities are issuable in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer or exchange of Securities in accordance with the Indenture.

    Pursuant to the Indenture, when this Security (or any portion thereof in integral multiples of 1,000 in principle amount) is presented to the Registrar with a request to register the transfer or to exchange it for an equal principal amount other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if the requirements hereunder for such transactions are met (including that such portions thereof are duly endorsed or accompanied by a written instrument of

8

transfer duly executed by the Holder thereof or by an attorney who is authorized in writing to act on behalf of the Holder). Subject to Section 2.4 of the Indenture, to permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar's request. No service charge shall be made for any registration of transfer or exchange or redemption of the Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or other similar governmental charge payable upon exchanges pursuant to Sections 2.14, 7.5 or 10.7 of the Indenture).

    Pursuant to the Indenture, neither the Company nor the Registrar shall be required to exchange or register a transfer of this Security (or any portion thereof):

        (1) for a period of 15 days prior to the day of any selection of any portion of this Security for redemption under Article 10 hereof;

        (2) so selected for redemption or, if a portion of this Security is selected for redemption, such portion thereof selected for redemption; or

        (3) surrendered for conversion or, if a portion of this Security is surrendered for conversion, such portion thereof surrendered for conversion.

    In the event of redemption, conversion or purchase of the Securities in part only, a new Security or Securities for the unredeemed, unconverted or unpurchased portion thereof will be issued in the name of the Holder hereof.

    12.  Persons Deemed Owners.

    The registered Holder of this Security shall be treated as its owner for all purposes.

    13.  Discharge Prior to Redemption or Stated Maturity.

    Subject to certain conditions contained in the Indenture, the Company may discharge its obligations under the Securities and the Indenture if (1) (a) all of the Outstanding Securities shall become due and payable at their scheduled Stated Maturity within one year or (b) all of the Outstanding Securities are scheduled for redemption within one year, and (2) the Company shall have deposited with the Trustee cash or, in the event of a conversion pursuant to the terms of the Indenture, Common Stock, sufficient to pay all amounts due and owing on all outstanding Securities on the date of their scheduled maturity or the scheduled date of redemption, as the case may be.

    14.  Amendment; Supplement; Waiver.

    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 under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority of the aggregate principal amount of the Outstanding Securities (or such lesser amount as shall have acted at a meeting pursuant to the provisions of the Indenture). The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon 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 Security or such other Security.

9

    No reference herein to the Indenture and no provision of this Security 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 Security at the times, places and rate, and in the coin or currency, herein prescribed or to convert this Security (or pay cash in lieu of conversion) as provided in the Indenture.

    15.  Defaults and Remedies.

    The Indenture provides that an Event of Default with respect to the Securities occurs when any of the following occurs:

    (a) the Company defaults in the payment of the Principal on this Security when the same becomes due and payable at its Stated Maturity, upon redemption, purchase, upon declaration, when due for purchase, by the Company or otherwise;

    (b) the Company defaults in the payment of an installment of Interest on this Security when it becomes due and payable and such default continues for a period of 30 days, whether or not such payment is prohibited by the terms of the Indenture;

    (c) the Company fails to perform or observe any other term, covenant or agreement contained in the Securities or this Indenture and the default continues for a period of 60 days after written notice of such failure, requiring the Company to remedy the same, shall have been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Securities;

    (d) the Company defaults under any Indebtedness for money borrowed by the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, the aggregate outstanding principal amount of which is in an amount in excess of $20.0 million, for a period of 60 days after written notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% in aggregate principal amount of the Outstanding Securities, which default (i) is caused the Company's failure to pay when due principal or premium, if any, of or interest on such Indebtedness by the end of the applicable grace period, if any, unless such Indebtedness is discharged or (ii) results in the acceleration of such Indebtedness because of a default with respect to such Indebtedness without such Indebtedness having been discharged or such non-payment or acceleration having been cured, waived, rescinded or annulled;

    (e) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, in an involuntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or any of its Subsidiaries that is a Significant Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, under any applicable U.S. federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or

    A Default under clause (c) or (d) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% of the principal amount of the Security at the time outstanding notify the Company and the Trustee, of the Default and the Company does not cure such Default (and such Default is not waived) within the time specified in clause (c) or (d) above after actual receipt of such notice. Any such notice must specify the Default, demand that it be remedied and state that such notice is a "Notice of Default".

    If an Event of Default shall occur and be continuing, the Principal of all the Securities may be declared due and payable in the manner and with the effect, and the Holder of this Security shall have the remedies and rights related thereto, provided in the Indenture.

CONVERSION NOTICE


TO:
 
InterMune, Inc.
3280 Bayshore Boulevard
Brisbane, CA 94005
