Proof of execution of any such instrument or of a writing appointing any such agent or proxy, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and the Company if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 9.6.

Promptly and in any case not later than ten days after setting a record date, the Company shall notify the Trustee, each Paying Agent and the Holders of such record date. If not set by the Company prior to the first solicitation of a Holder made by any Person in respect of any such action, or, in the case of any such vote, prior to such vote, the record date for any such action or vote shall be the 30th day (or, if later, the date of the most recent list of Holders required to be provided pursuant to Section 15.1) prior to such first solicitation or vote, as the case may be. With regard to any record date, the Holders on such date (or their duly appointed agents or proxies), and only such Persons, shall be entitled to give or take, or vote on, the relevant action, whether or not such Holders remain Holders after such record date. Notwithstanding the foregoing, the Company shall not set a record date for, and the provisions of this paragraph shall not apply with respect to, any notice, declaration or direction referred to in the next paragraph.

Promptly after such receipt by the Trustee, and as soon as practicable thereafter, the Trustee shall notify the Company and the Holders of any such record date so fixed. The Holders on such record date (or their duly appointed agents or proxies), and only such Persons, shall be entitled to join in such notice, declaration or direction, whether or not such Holders remain Holders after such record date; provided that, unless such notice, declaration or direction shall have become effective by virtue of Holders of the requisite principal amount of Securities on such record date (or their duly appointed agents or proxies) having joined therein on or prior to the 90th day after such record date, such notice, declaration or direction shall automatically and without any action by any Person be canceled and of no further effect. Nothing in this paragraph shall be construed to prevent a Holder (or a duly appointed agent or proxy thereof) from giving, before or after the expiration of such 90-day period, a notice, declaration or direction contrary to or different from, or, after the expiration of such period, identical to, the notice, declaration or direction to which such record date relates, in which event a new record date in respect thereof shall be set pursuant to this paragraph. In addition, nothing in this paragraph shall be construed to render ineffective any notice, declaration or direction of the type referred to in this paragraph given at any time to the Trustee and the Company by Holders (or their duly appointed agents or proxies) of the requisite principal amount of Securities on the date such notice, declaration or direction is so given. 14 24 Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Successor Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Successor Security. The provisions of this Section 1.4 are subject to the provisions of Section 9.5. SECTION 1.5. Notices, Etc., to Trustee and Company.

Ziegler, Esq., or (2) the Company by the Trustee or any Paying Agent or by any Holder of Securities shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing, mailed, first-class postage prepaid, or telecopied and confirmed by mail, first-class postage prepaid, or delivered by hand or overnight courier, addressed to the Company at, Orbital Sciences Corporation, 21700 Atlantic Boulevard, Dulles, VA 20166 (facsimile number: (703) 406-5572, Attention: General Counsel, or at any other address previously furnished in writing to the Trustee by the Company.

Notice to Holders of Securities; Waiver. Except as otherwise expressly provided herein, where this Indenture provides for notice to Holders of Securities of any event, such notice shall be sufficiently given to Holders of Securities if in writing and mailed, first-class postage prepaid, to each Holder of a Security affected by such event, at the address of such Holder as it appears in the Security Register, not earlier than the earliest date and not later than the latest date prescribed for the giving of such notice. Such notice shall be conclusively deemed to have been given and received by Holders when such notice is mailed, whether or not such Holder receives such notice. In any case where notice to Holders of Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Security shall affect the sufficiency of such notice with respect to other Holders of Securities given as provided above. In case by reason of the suspension of or irregularities in regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification to Holders of Securities as shall be made with the approval of the Trustee, which approval shall not be unreasonably withheld, shall constitute a sufficient notification to such Holders for every purpose hereunder. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. SECTION 1.7. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. SECTION 1.8. Successors and Assigns. All covenants, stipulations, promises and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

SECTION 1.10. Benefits of Indenture. Except as provided in the next sentence, nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors and assigns hereunder and the Holders of Securities, any benefit or legal or equitable 16 26 right, remedy or claim under this Indenture. The provisions of Article Thirteen are intended to be for the benefit of, and shall be enforceable directly by, the holders of Senior Indebtedness of the Company. SECTION 1.11. Governing Law. THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK, THE UNITED STATES OF AMERICA, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS. SECTION 1.12. Legal Holidays. In any case where any Interest Payment Date, Redemption Date, Repurchase Date or Stated Maturity of any Security or the last day on which a Holder of a Security has a right to convert his Security shall not be a Business Day at any Place of Payment or Place of Conversion, as the case may be, then (notwithstanding any other provision of this Indenture or of the Securities) payment of interest or principal and premium, if any, or delivery for conversion of such Security need not be made at such Place of Payment or Place of Conversion, as the case may be, on or by such day, but may be made on or by the next succeeding Business Day at such Place of Payment or Place of Conversion, as the case may be, with the same force and effect as if made on the Interest Payment Date, Redemption Date or Repurchase Date, or at the Stated Maturity or by 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, Repurchase Date, Stated Maturity or last day for conversion, as the case may be through such next succeeding Business Day.

If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. Until such time as this Indenture shall be qualified under the Trust Indenture Act, this Indenture, the Company and the Trustee shall be deemed for all purposes hereof to be subject to and governed by the Trust Indenture Act to the same extent as would be the case if this Indenture were so qualified on the date hereof.

Dated: ORBITAL SCIENCES CORPORATION By:______________________________________ Name: Title: Attest By:__________________________________ 26 36 [REVERSE OF NOTE] This Security is one of a duly authorized issue of securities of the Company designated as its "5% Convertible Subordinated Notes due 2002" (herein called the "Securities"), limited in aggregate principal amount to U.S.$100,000,000, issued and to be issued under and pursuant to an Indenture, dated as of September 16, 1997 (herein called the "Indenture"), between the Company and Deutsche Bank AG, New York Branch, Trustee, herein called the "Trustee" (which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the holders of Senior Indebtedness of the Company and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. The Securities are issuable in the denomination of U.S.$1,000 and integral multiples thereof. As provided in the Indenture and subject to the limitations therein set forth, the Securities are exchangeable (a) at the office of the Trustee, or at such other office or agency of the Company as may be designated by it for such purpose in The City of New York or (b) so long as the Securities are listed on the Luxembourg Stock Exchange and the rules of the Luxembourg Stock Exchange shall so require (and subject to the right of the Company to terminate the appointment of any Security Registrar (as defined below)), the office of Banque de Luxembourg, International Department, 14 Boulevard Royal, L-2449 Luxembourg, or at such other offices or agencies outside the United States as the Company may designate (each a "Security Registrar"). No sinking fund is provided for the Securities. Subject to the redemption of Tax Affected Securities as described below, the Securities will not be redeemable at the option of the Company prior to October 1, 2000. At any time on or after October 1, 2000 and prior to maturity, the Securities are subject to redemption at the option of the Company at any time, in whole or in part, upon not less than 20 nor more than 60 days' notice to the Holders prior to the Redemption Date, at the following Redemption Prices (expressed as percentages of the principal amount thereof) if such Redemption Date occurs during the 12-month period beginning October 1: YEAR PERCENTAGE ---- ---------- 2000 102% 2001 101% and 100% on October 1, 2002; together, in each case, with accrued interest to, but excluding the Redemption Date; Securities that are Tax Affected Securities are also redeemable, in whole but not in part, under the circumstances described in the next succeeding paragraph, at a Redemption Price equal to 100% of the principal amount thereof plus interest accrued to, but excluding, the Redemption Date; provided, however, that interest installments on Securities whose Stated Maturity is on or prior to such Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof all as provided in the Indenture. 27 37 If, as a result of a Tax Law Change, the Company is or would become obligated on the next succeeding Interest Payment Date to pay to the Holder of any Security Additional Amounts, as described in the third paragraph (following the legends) of the face of this Security, and such obligation cannot be avoided by the Company taking reasonable measures available to it, then the Company may, at its option, redeem the Tax Affected Securities in whole, but not in part, at any time, on giving not less than 20 days' notice to the Holders prior to the Redemption Date, at a Redemption Price equal to 100% of the principal amount plus interest accrued to, but excluding, the Redemption Date, and any Additional Amounts then payable; provided, that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Company would be obligated to withhold or pay any such Additional Amounts were a payment in respect of the Tax Affected Securities then made. Prior to the giving of any notice of redemption pursuant to this paragraph, the Company shall deliver to the Trustee (a) an Officers' Certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Company so to redeem have occurred and (b) an Opinion of Counsel selected by the Company to the effect that the circumstances referred to above in this paragraph exist. The Trustee shall accept such opinion as sufficient evidence of the satisfaction of the conditions precedent described above, in which event it shall be conclusive and binding on the Holder. The Company's right to redeem the Tax Affected Securities shall continue as long as the Company is obligated to pay such Additional Amounts, notwithstanding that the Company shall have made payments of Additional Amounts. In the event of a redemption of less than all of the Securities, the Trustee will not be required (a) to register the transfer or exchange of Securities for a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities called for such redemption or (B) to register the transfer or exchange of any Security, or portion thereof, called for redemption. In any case where the due date for the payment of the principal or premium, if any, or interest, including Additional Amounts and Additional Interest on, any Security or the last day on which a Holder of a Security has a right to convert his Security shall not be a Business Day, at any Place of Payment or Place of Conversion, as the case may be, then payment of principal, premium, if any, or interest, including Additional Amounts and Additional Interest, or delivery for conversion of such Security need not be made on or by such date at such place but may be made on or by the next succeeding Business Day at such Place of Payment or Place of Conversion, as the case may be, with the same force and effect as if made on the date for such payment or the date fixed for redemption or repurchase, or by such last day for conversion, and no interest shall accrue on the amount so payable for the period from and after such date through such next succeeding Business Day. Subject to and upon compliance with the provisions of the Indenture, the Holder of this Security is entitled, at his or her option, at any time on or prior to the close of business on the Business Day immediately preceding October 1, 2002, or in case this Security or a portion hereof is called for redemption or the Holder hereof has exercised his or her right to require the Company to repurchase this Security or such portion hereof then in respect of this Security until 28 38 and including, but (unless the Company defaults in making the payment due upon redemption or repurchase, as the case may be) not after, the close of business on the Business Day next preceding the Redemption Date or the Repurchase Date, as the case may be, to convert this Security (or any portion of the principal amount hereof that is an integral multiple of U.S.$1,000, provided that the unconverted portion of such principal amount is U.S.$1,000 or any integral multiple thereof) into fully paid and nonassessable Common Stock of the Company at an initial Conversion Price of U.S.$28.00 for each share of Common Stock (or at the current adjusted Conversion Price if an adjustment has been made as provided in the Indenture). In order to convert a Certificated Security, a Holder must surrender this Security, duly endorsed or assigned to the Company or in blank to a Conversion Agent. In case surrender shall be made during the period from the close of business of any Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date ("Interest Period"), such Holder shall also be required to pay in New York Clearing House or other funds acceptable to the Company an amount equal to the interest payable on such Interest Payment Date on the principal amount of this Security then being converted, and also to deliver the conversion notice hereon duly executed, to the Company at the office of the Trustee in The City of New York or the Conversion Agent in Luxembourg, or at such other office or agency of the Company, subject to any laws or regulations applicable thereto and subject to the right of the Company to terminate the appointment of any Conversion Agent as may be designated by it for such purpose in The City of New York, or Luxembourg, or at such other offices or agencies as the Company may designate (each a "Conversion Agent"). No cash payment or adjustment shall be made on conversion of this Security for interest accrued hereon from the Interest Payment Date next preceding the date of conversion or for dividends on the Common Stock issued on conversion hereof subject only (i) in the case of a conversion during an Interest Period, to the obligation of the Holder to pay to the Company an amount equal to the accrued interest in respect of this Security as provided in the immediately preceding paragraph and the obligation of the Company to pay such accrued interest to the Holder of this Security (or any Predecessor Security) of record on the Regular Record Date that commences such Interest Period and (ii) in the case of a conversion on an Interest Payment Date, the obligation of the Company to pay to the Holder of this Security (or any Predecessor Security) of record on the Regular Record Date next preceding such Interest Payment Date interest accrued hereon from such next preceding Interest Payment Date. Following a conversion, the Company shall promptly deliver to the Holder the fixed number of shares of Common Stock (together with any cash adjustment, as provided in the Indenture) into which this Security is convertible and such delivery will be deemed to satisfy the Company's obligation to pay the principal amount of this Security. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional interest (calculated to the nearest 1/100th of a share) the Company shall pay a cash adjustment as provided in the Indenture. The Conversion Price is subject to adjustment as provided in the Indenture. In addition, the Indenture provides that in case of certain consolidations or mergers to which the Company is a party (other than a consolidation or merger which does not result in any reclassification, conversion, exchange or cancellation of the Common Stock) or the transfer of all or substantially all of the property and assets of the Company, the Indenture shall be amended, without the consent of any Holders of 29 39 Securities, so that this Security, if then Outstanding, will be convertible thereafter, during the period this Security shall be convertible as specified above, only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger or transfer by a holder of the number of shares of Common Stock of the Company into which this Security could have been converted immediately prior to such consolidation, merger or transfer (assuming such holder of Common Stock is not a Constituent Person (as defined in the Indenture) and failed to exercise any rights of election and received per share the kind and amount received per share by a plurality of Non-electing Shares). No adjustment in the Conversion Price will be made until such adjustment would require an increase or decrease of at least one percent of such price, provided that any adjustment that would otherwise be made will be carried forward and taken into account in the computation of any subsequent adjustment. Subject to certain limitations in the Indenture, at any time when the Company is not subject to Section 13 or 15(d) of the United States Securities Exchange Act of 1934, as amended, upon the request of a Holder of a Restricted Security or the holder of Common Stock issued upon conversion thereof the Company will promptly furnish or cause to be furnished Rule 144A Information (as defined in the Indenture) to such Holder of Restricted Securities or such holder of Common Stock issued upon conversion of Restricted Securities, or to a prospective purchaser of any such security designated by any such Holder or holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such security. The Holder of this Security and the Common Stock issuable upon conversion thereof is entitled to the benefits of a Registration Rights Agreement (subject to the provisions thereof), dated as of September 16, 1997, between the Company and the Initial Purchasers. In order to participate in any such registration, Holders must obtain from the Trustee, and complete, sign and deliver to the Company, a selling securityholder questionnaire, provide certain other information with respect to the Holder and otherwise comply with the provisions of the Registration Rights Agreement. The Company shall pay Additional Interest to the Holder of this Security as provided for in the Registration Rights Agreement. Whenever in this Security there is a reference, in any context, to the payment of the principal of, premium, if any, or interest on, or in respect of, this Security, such mention shall be deemed to include mention of the payment of Additional Interest payable as described in the preceding paragraph to the extent that, in such context, Additional Interest is, was or would be payable in respect of this Security and express mention of the payment of Additional Interest (if applicable) in any provisions of this Security shall not be construed as excluding Additional Interest in those provisions of this Security where such express mention is not made. If a Fundamental Change (as defined in the Indenture) occurs at any time on or prior to October 1, 2002, each Holder shall have the right, at such Holder's option, to require the Company to repurchase all of such Holder's Securities (or the portion of such Securities that is $1,000 or an integral multiple of $1,000 in excess thereof) on the 45th day after notice thereof. Such payment shall be made at the following Repurchase Prices (expressed as percentages of the principal amount thereof) in the event of a Fundamental Change occurring during the 12-month period beginning October 1, (September 17, 1997 in the case of the first period): 30 40 Year Percentage ---- ---------- 1997 102% 1998 102% 1999 102% 2000 102% 2001 101% and 100% at October 1, 2002; together in each case, with accrued interest to, but excluding, the Repurchase Date; provided in each case that if the Applicable Price (as defined in the Indenture) is less than the Reference Market Price (as defined in the Indenture), the Company shall repurchase such Securities at a price equal to the product of (i) foregoing Repurchase Price multiplied by (ii) the fraction obtained by dividing the Applicable Price by the Reference Market Price. In each case, the Company shall also pay accrued interest, if any, on such Securities to, but excluding, the Repurchase Date; provided that if such Repurchase Date is April 1 or October 1, then the interest payable on such date shall be paid to the Holder of record of the Securities on the Regular Record Date. Whenever in this Security there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to the Repurchase Price payable in respect of such Security to the extent that such Repurchase Price is, was or would be so payable at such time, and express mention of the Repurchase Price in any provision of this Security shall not be construed as excluding the Repurchase Price in those provisions of this Security when such express mention is not made. [The following paragraph shall appear in each security that is not a Global Security: In the event of redemption, repurchase or conversion of this Security in part only, a new Security or Securities for the unredeemed, unrepurchased or unconverted portion hereof will be issued in the name of the Holder hereof.] [The following paragraph shall appear in the Global Security: In the event of a deposit or withdrawal of an interest in this Security, including an exchange, transfer, redemption, repurchase or conversion of this Security in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the rules and procedures of the Depositary.] The indebtedness evidenced by this Security and the obligations of the Company under the Indenture are to the extent and in the manner provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness (as defined in the Indenture) of the Company, and this Security is issued subject to such provisions of the Indenture with respect thereto.

Securities bearing the manual or facsimile signature of an individual or individuals who were at any time the proper officer or 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 such Securities. 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 or to its order for authentication (or to the Authenticating Agent), together with a Company Order for the authentication and delivery of such Securities, and the Trustee or an Authenticating Agent in accordance with such Company Order shall authenticate and make available for delivery 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 the Trustee or an Authenticating Agent by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. SECTION 3.4. Global Securities; Book-Entry Provisions; Certificated Securities. (a) Securities Generally (1) Securities issued to QIBs in reliance on Rule 144A and Securities offered and sold in reliance upon Regulation S shall be issued initially in the form of a global security (the "Global Security") in definitive, fully registered form without interest coupons bearing the Restricted Securities Legends and the Global Security Legend. (2) Securities not in global form (each a "Certificated Security") shall be issued only upon the events described in Section 3.4(b)(2) and shall bear the Restricted Securities Legends, as required by this Indenture. (b) Global Security (1) A Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated by the Company for such Global Security or a nominee thereof and deposited on behalf of the purchasers of the Securities represented thereby with the Trustee at its New York office, as custodian for the Depositary therefor, and such Global Security shall constitute a single Security for all purposes of this Indenture. The aggregate principal amount of such Global Security may from time to time be increased or decreased by adjustments made by the Security Registrar on a schedule thereto, as provided herein. (2) Notwithstanding any other provision in this Indenture, no transfer of a Global Security, in whole or in part, may be registered in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (i) such Depositary (A) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (B) has ceased to be a clearing agency registered as such under the Exchange Act or announces an intention permanently to cease business or does in fact do so or (ii) there shall have occurred and be continuing an Event of Default with respect to such Global Security. In such event, if a Successor Depositary for such Global Security is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Company will execute, and the Trustee, upon receipt of an Officers' Certificate directing the 41 51 authentication and delivery of Securities, will authenticate and deliver, Certificated Securities, and the Company will execute and deliver to the Trustee Certificated Securities in any authorized denominations in an aggregate principal amount equal to the principal amount of such Global Security in exchange for such Global Security. (3) If any Global Security is to be canceled in whole, it shall be surrendered by or on behalf of the Depositary or its nominee to the Trustee, as Security Registrar, pursuant to Section 3.4(b)(2), for cancellation as provided in this Article Three. Upon any such surrender of a Global Security, the Trustee shall, subject to this Article Three, authenticate and deliver any Certificated Security (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depositary or its authorized representative. Upon the request of the Trustee, the Company shall promptly make available to the Trustee a reasonable supply of Certificated Securities. The Trustee shall be entitled to rely upon any order, direction or request of the Depositary or its authorized representative which is given or made pursuant to this Article Three or reasonably believed by it to be properly given. (4) The Depositary or its nominee, as registered owner of a Global Security, shall be the Holder of such Global Security for all purposes under the Indenture and the Securities, and owners of beneficial interests in a Global Security shall hold such interests pursuant to the procedures of the Depositary. Accordingly, any such owner's beneficial interest in a Global Security will be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its Participants (as defined below) and such owners of beneficial interests in a Global Security will not be considered the owners or holders thereof. (5) All payments on a Global Security will be made to the Depositary or its nominee, as the case may be, as the registered owner and holder of such Global Security and the Company will be fully discharged by payment to the Depositary from any responsibility or liability in respect of each amount so paid. Upon receipt of any such payment of principal, interest, premium, Additional Interest, if any, or Additional Amounts, if any, in respect of a Global Security, the Depositary will immediately credit Participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such Global Security as shown on the records of the Depositary. (6) Owners of beneficial interests in Global Securities shall be entitled or required, as the case may be, under the circumstances described in this Section 3.4(b)(2), to receive physical delivery of Certificated Securities. (7) Any Global Security may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Indenture as may be required by the custodian, the Depositary or by the National Association of Securities Dealers, Inc. in order for the Securities to be tradable on The PORTAL Market or as may be required for the Securities to be tradable on any other market developed for trading of securities pursuant to Rule 144A or Regulation S or required to comply with any applicable law or any regulation thereunder or with the rules and regulations of Euroclear, Cedel or any securities 42 52 exchange or automated quotation system upon which the Securities may be listed or traded or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Securities are subject. (c) Book-Entry Provisions. This Section 3.4(c) shall apply to the Global Security deposited with or on behalf of the Depositary. The Company shall execute and the Trustee shall, in accordance with this Section 3.4(c), authenticate and deliver one Global Security that shall (i) represent an aggregate amount equal to the aggregate principal amount of such outstanding Securities as the Company shall have directed the Trustee to authenticate in the form of a Global Security and (ii) bear the Global Security Legend and, as applicable, the Restricted Securities Legends. At such time as all interests in a Global Security have been redeemed, repurchased, converted, canceled, or transferred to a transferee who receives Certificated Securities, such Global Security shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in the Global Security is transferred to the Company or its Subsidiary, the principal amount of such interest in the Global Security shall be deemed cancelled, and in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, the principal amount of the Global Security shall be appropriately reduced and an endorsement shall be made on such Global Security, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. Members of, or participants in, the Depositary ("Participants") shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary or by the Trustee, as the custodian of the Depositary, 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 herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants, the operation of customary practices of such Depositary governing the exercise of the rights of a Holder of a beneficial interest in any Global Security. (d) The Certificated Securities. Except as provided in this Indenture, owners of beneficial interest in Global Security will not be entitled to receive physical delivery of Certificated Securities. (e) Cessation of Restrictions. After a transfer of a Certificated Security or a beneficial interest in the Global Security during the period of the effectiveness of a registration statement with respect to the Securities as contemplated by the Registration Rights Agreement or pursuant to Rule 144(k) of the Securities Act, all requirements pertaining to the Restricted Securities Legends on such Certificated Security or beneficial interest in the Global Security will cease to apply and a Certificated Security or a Global Security, as the case may be, without 43 53 Restricted Securities Legends will be issued or the principal amount of the Global Security without the Restricted Securities Legends will be increased and the principal amount of the Global Security with the Restricted Securities Legends will be reduced correspondingly, as the case may be, with respect to such beneficial interests pursuant to Section 3.5(c)(ii). SECTION 3.5. Registration, Registration of Transfer and Exchange; Restrictions on Transfer. (a) General. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company designated pursuant to Section 10.2 (including the office of Deutsche Bank AG, New York Branch, in The City of New York, New York and the office of Banque de Luxembourg, in Luxembourg) being herein sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Securities and transfers and exchanges of Securities as herein provided. Included in the books and records for the Securities shall be notations as to whether such Securities have been paid, exchanged or transferred and canceled or lost, stolen, mutilated or destroyed and whether such Securities have been replaced. In the case of the replacement of any of the Securities, the Security Registrar shall keep a record of the Security so replaced and the Security issued in replacement thereof. In the case of the cancellation of any of the Securities, the Security Registrar shall keep a record of the Security so canceled and the date on which such Security was canceled. The costs and expenses of effecting any exchange or registration of transfer, except for the expense of delivery by other than regular mail (if any) and except for the payment of a sum sufficient to cover any tax or other governmental charges or insurance charges that may be imposed with respect thereto, shall be borne by the Company. Upon surrender for registration of transfer of any Security at an office or agency of the Company designated pursuant to Section 10.2 for such purpose with a request to register a transfer or to exchange such Security for an equal principal amount of Securities of the same series of other denominations, the Security Registrar shall register the transfer or make the exchange if its requirements for such transactions are met. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor and bearing such restrictive legends as may be required by this Indenture, at the Security Registrar's request. At the option of the Holder, and subject to the further provisions of this Section 3.5, Securities may be exchanged for other Securities of any authorized denomination and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any such office or agency maintained by the Company pursuant to Section 10.2. Whenever any Securities are so surrendered for exchange, and subject to the further provisions of this Section 3.5, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. Every Security presented or surrendered for 44 54 registration of transfer or for exchange shall (if so required by the Company or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and, subject to the other provisions of this Section 3.5, entitled to the same benefits, under and subject to the same restrictions imposed by this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Except as provided in Section 3.6, no service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.4, 8.5, 11.8, 12.2 or 14.2(e) (other than, in the case of Securities where the Common Stock is to be issued or delivered in a name other than that of the Holder of the Security) not involving any transfer and other than any stamp and other similar duties, if any, which may be imposed in connection with any such transfer or exchange by the United States or any political subdivision thereof or therein, which shall be paid by the Company. In the event of a redemption of the Securities in part, neither the Company nor the Security Registrar will be required (a) to register the transfer of or exchange of Securities for a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities called for such redemption or (b) to register the transfer of or exchange any Security, or portion thereof, called for redemption. (b) Restrictions on Transfer. Notwithstanding any provision to the contrary herein, so long as a Global Security remains outstanding and is held by or on behalf of the Depositary, transfers of a Global Security, in whole or in part, or of any beneficial interest therein, shall only be made in accordance with Section 3.4 and this Section 3.5; provided, however, that beneficial interests in a Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Global Security in accordance with the transfer restrictions set forth in the Restricted Securities Legends on such Security. As used herein, "transfer" encompasses any sale, pledge, transfer or other disposition whatsoever. (i) Except for transfers or exchanges made in accordance with any of clauses (ii), (iii) and (iv) of this Section 3.5(b), transfers of a Global Security shall be limited to transfers of such Global Security in whole, but not in part, to nominees of the Depositary or to a successor of the Depositary or such successor's nominee. (ii) Global Security to Certificated Security. If in the event that Certificated Securities are to be issued pursuant to Section 3.4(b)(2), upon receipt by the Trustee, as Security Registrar, at its office in The City of New York of (1) instructions from the Company directing the Trustee, as Security Registrar, to authenticate and to deliver one or more Certificated Securities of the same aggregate principal amount at 45 55 maturity as the beneficial interest in the Global Security to be issued, such instructions to contain the name or names of the designated transferee or transferees, the authorized denomination or denominations of the Certificated Securities to be so issued and appropriate delivery instructions and (2) such other certifications, legal opinions or other information as the Company or the Trustee may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, then the Company shall execute, and the Trustee, as Security Registrar, shall authenticate and deliver, one or more Certificated Securities of the same aggregate principal amount at maturity in accordance with the instructions referred to above. If such Certificated Securities are issued after the close of business at the office or agency where such exchange occurs on any Record Date and before the opening of business at such office or agency on the next succeeding Interest Payment Date, interest will be payable to the Holders of the Certificated Securities on such Interest Payment Date as though the Holders thereof had held such Securities as of the Record Date, subject to the provisions of Section 3.7. (iii) Certificated Securities to Certificated Securities. If a Holder of a Certificated Security wishes at any time to transfer such Certificated Security to a person who is required to take delivery thereof in the form of a Certificated Security, such Holder may, subject to the restrictions on transfer set forth herein and in such Certificated Security, cause the exchange of such Certificated Security for one or more Certificated Securities of any authorized denomination or denominations and of the same aggregate principal amount at maturity. Upon receipt by the Trustee, as Security Registrar, at its office in The City of New York of (1) such Certificated Security, duly endorsed as provided herein, (2) instructions from such Holder directing the Trustee, as Security Registrar, to authenticate and deliver one or more Certificated Securities of the same aggregate principal amount at maturity as the Certificated Security to be exchanged, such instructions to contain the name or names of the designated transferee or transferees, the authorized denomination or denominations of the Certificated Securities to be so issued and appropriate delivery instructions, and (3) such other certifications, legal opinions or other information as the Company may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, then the Trustee, as Security Registrar, shall cancel or cause to be canceled such Certificated Security and concurrently therewith, the Company shall execute, and the Trustee shall authenticate and deliver, one or more Certificated Securities of the same aggregate principal amount at maturity, in accordance with the instructions referred to above. (c) Restricted Securities Legends. Upon their original issuance, the Securities shall be Restricted Securities, shall bear the Restricted Securities Legends and shall be issued as a Global Security registered in the name of Cede & Co., as nominee of, and delivered to, The Depository Trust Company ("DTC"), as Depositary, or pursuant to DTC's instructions, held by the Trustee, as custodian for DTC, for credit by DTC to the respective accounts of Participants within DTC for further credit to the respective accounts of beneficial owners of the Securities represented thereby (or such other accounts as they may direct). The Securities and their 46 56 respective Successor Securities shall bear, or be subject to the provisions of, the applicable Restricted Securities Legends, subject to the following: (i) Subject to the following clauses of this Section 3.5(c), a Certificated Security that has been issued as a result of events set forth in Section 3.4(b)(2) shall bear the Restricted Securities Legends, if any, borne by the Global Security for which the Certificated Security was exchanged. (ii) At any time after the Securities may be freely transferred without registration under the Securities Act or without being subject to transfer restrictions pursuant to the Securities Act (including, without limitation, pursuant to Rule 144(k) of the Securities Act or pursuant to an effective registration statement under the Securities Act), (i) a new Security (other than a Global Security) that does not bear the Restricted Securities Legends may be issued in exchange for or in lieu of a Security or any portion thereof that bears the Restricted Securities Legends and the Trustee shall authenticate and deliver such a new Security in exchange for or in lieu of such other Security as provided in this Article Three and (ii) in the case of any beneficial interest in a Global Security, such beneficial interest shall no longer be subject to the provisions set forth in the Restricted Securities Legends. The Company shall inform the Trustee in writing of the effective date of any such registration statement registering the Securities under the Securities Act and shall notify the Trustee at any time when a prospectus must be delivered with respect to Securities to be sold pursuant to such registration statement. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned registration statement. (iii) A new Security that does not bear the Restricted Securities Legends may be issued in exchange for or in lieu of a Security or any portion thereof that bears the Restricted Securities Legends if, in the judgment of the Company, placing the Restricted Securities Legends upon such new Security is not necessary to ensure compliance with the registration requirements of the Securities Act, and the Trustee, at the direction of the Company, shall authenticate and deliver such a new Security as provided in this Article Three. (iv) Except in connection with a transfer of a beneficial interest in the Global Security pursuant to an effective registration statement, in which case the Restricted Securities Legends shall not apply to such beneficial interest in the Global Security so transferred at the request of the Holder, if a Global Security is issued upon the transfer, exchange or replacement of the Global Security bearing the Restricted Securities Legends and if a request is made to remove such Restricted Securities Legends from the Global Security, the Global Security so issued shall bear the Restricted Securities Legends, or the Restricted Securities Legends shall not be removed, as the case may be, unless there is delivered to the Company such satisfactory evidence, which may include an Opinion of Counsel, as may be reasonably required by the Company, that neither the legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof will not violate the registration and prospectus delivery requirements of the 47 57 Securities Act. Upon provision of such satisfactory evidence, the Company shall direct the Trustee and the Trustee shall authenticate and deliver the Global Security that does not bear such legend. (d) Common Stock. Any stock certificate representing Common Stock issued upon conversion of the Securities shall bear the Restricted Securities Legends borne by such Securities, to the extent required by this Indenture, unless such Common Stock has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or sold pursuant to Rule 144(k) of the Securities Act, or unless otherwise agreed by the Company in writing with written notice thereof to the Common Stock transfer agent. With respect to the transfer of Common Stock restricted hereunder, any deliveries of certificates, legal opinions or other instruments that would be required to be made to the Security Registrar in the case of transfer of Securities, as described above, shall instead be made to the transfer agent of the Common Stock. SECTION 3.6. Mutilated, Destroyed, Lost or Stolen Securities. If any mutilated Security is surrendered to the Trustee or to a Security Registrar outside the United States, the Company shall execute, the Trustee or an Authenticating Agent shall authenticate and the Trustee or Security Registrar shall deliver in exchange therefor a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. If there be delivered to the Company and either to the Trustee or to a Security Registrar outside the United States: (1) evidence to their satisfaction of the destruction, loss or theft of any Security, and (2) such security or indemnity as may be satisfactory to the Company and the Trustee and such Security Registrar to save each of them and any agent of either of them harmless, then, in the absence of actual notice to the Company, the Trustee or the Security Registrar that such Security has been acquired by a bona fide purchaser, the Company shall execute, and upon its request, the Trustee or an Authenticating Agent shall authenticate and the Trustee or Security Registrar shall deliver in lieu of any such destroyed, lost or stolen Security or in exchange for the 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 the issuance of any new Security under this Section 3.6, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may 48 58 be imposed in relation thereto (other than any stamp and other duties, if any, which may be imposed in connection therewith by the United States of America or any political subdivision thereof or therein, which shall be paid by the Company) and any other expenses (including the fees and expenses of the Trustee, any Paying Agent and any Security Registrar) connected therewith. Every new Security issued pursuant to this Section 3.6 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, 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 3.6 are exclusive and shall preclude (to the extent lawful) all other rights and remedies of any Holder with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. SECTION 3.7. Payment of Interest; Interest Rights Preserved. Interest on any 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. Any interest on any Security which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below: (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security, and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this Clause. Thereupon, the Trustee shall fix the Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities at such Holder's address as it appears in the Security Register, not less than 10 days 49 59 prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. No cash payment or adjustment shall be made on conversion of a Security for interest accrued thereon from the Interest Payment Date next preceding the date of conversion or for dividends on the Common Stock issued on conversion thereof subject only (i), in the case of a conversion after the close of business on any Regular Record Date and prior to the next succeeding Interest Payment Date, to the obligation of the Holder to pay to the Company an amount equal to the accrued interest in respect of such Security as provided in Section 2.2 and the obligation of the Company to pay such accrued interest to the Holder of such Security (or any Predecessor Security) of record on the Regular Record Date next preceding such Interest Payment Date and (ii) in the case of a conversion on an Interest Payment Date, the obligation of the Company to pay to the Holder of such Security (or any Predecessor Security) of record on the Regular Record Date next preceding such Interest Payment Date interest accrued thereon from such next preceding Interest Payment Date. SECTION 3.8. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company or 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, premium, if any, and (subject to Section 3.7) interest on such Security and for all other purposes whatsoever, 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. None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 50 60 Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any Depositary, as a Holder, with respect to such Global Security or impair, as between such Depositary and owners of beneficial interests in such Global Security, the operation of customary practices governing the exercise of the rights of such Depositary (or its nominee) as Holder of such Global Security. SECTION 3.9. Cancellation. All Securities surrendered for payment, redemption, repurchase, registration of transfer or exchange or conversion shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities so delivered to the Trustee shall be canceled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section 3.9. The Trustee shall destroy all canceled Securities in accordance with applicable law and its customary practices in effect from time to time. SECTION 3.10. Computation of Interest. Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months. SECTION 3.11. CUSIP Numbers. The Company in issuing Securities may use "CUSIP" numbers (if then generally in use) in addition to serial numbers; if so, the Trustee shall use such "CUSIP" numbers in addition to serial numbers in notices of redemption and repurchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such CUSIP numbers either as printed on the Securities or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Securities, and any such redemption or repurchase shall not be affected by any defect in or omission of such CUSIP numbers. ARTICLE FOUR SATISFACTION AND DISCHARGE SECTION 4.1. Satisfaction and Discharge of Indenture. This Indenture shall, upon Company Request, cease to be of further effect (except as to any surviving rights of conversion, or registration of transfer or exchange, or replacement of Securities herein expressly provided for and any right to receive Additional Amounts and Additional Interest, if any, as provided in the form of Security set forth in Section 2.2 and the Company's obligations to the Trustee pursuant to Section 6.7), and the Trustee, at the expense of the Company, shall execute proper instruments in form and substance satisfactory to the Trustee acknowledging satisfaction and discharge of this Indenture, when 51 61 (1) either (A) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 3.6 and (ii) Securities for whose payment money has theretofore been deposited with the Trustee or the Paying Agent in trust or segregated and held in trust by the Company (whether or not such money has been repaid to the Company or discharged from such trust, as provided in Section 10.3)) have been delivered to the Trustee for cancellation; or (B) all such Securities not theretofore delivered to the Trustee or the Paying Agent or its agent for cancellation (other than Securities referred to in clauses (i) and (ii) of clause (1)(A) above) (i) have become due and payable, or (ii) will have become due and payable at their Stated Maturity within one year, or (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case of clause (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds (immediately available to the Holders in the case of clause (i)) in trust an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal, premium, if any, and interest (including any applicable Additional Amounts and Additional Interest) to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and (3) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 6.7, the obligations of the Company to any Authenticating Agent under Section 6.12, the obligation of the Company to pay Additional Amounts and, if money shall have been deposited with the Trustee pursuant to clause (1)(B) of this Section 4.1, the obligations of the Trustee under Section 4.2 and the last paragraph of Section 10.3 shall survive, and until such time as any Securities described in this Section 4.1 become due and payable or are redeemable, the Company shall remain obligated to the holders of 52 62 such Securities for all payments due thereunder, including the delivery of additional funds to the Trustee if the funds previously provided to the Trustee pursuant this Section 4.1 are insufficient to satisfy in full the amount of such payments. Funds held in trust pursuant to this Section are not subject to the provisions of Article Thirteen. SECTION 4.2. Application of Trust Money. Subject to the provisions of the last paragraph of Section 10.3, all money deposited with the Trustee pursuant to Section 4.1 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent), as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, if any, and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. All moneys deposited with the Trustee pursuant to Section 4.1 (and held by it or any Paying Agent) for the payment of Securities subsequently converted shall be returned to the Company upon a Company Request. ARTICLE FIVE REMEDIES SECTION 5.1. Events of Default. "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 occasioned by the provisions of Article Thirteen or 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): (1) default in the payment of the principal of or premium, if any, on any Security at its Maturity, whether or not such payment is prohibited by the subordination provisions of Article Thirteen; or (2) default in the payment of any interest (including any Additional Amounts or Additional Interest, if any) upon any Security when it becomes due and payable, and continuance of such default for a period of 30 days, whether or not such payment is prohibited by the subordination provisions of Article Thirteen; or (3) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in the performance or breach of which is specifically dealt with elsewhere in this Section), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, 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 53 63 Securities a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or (4) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable bankruptcy, moratorium of payments, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of substantially all of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; or (5) the commencement by the Company of a voluntary case or proceeding under any applicable bankruptcy, moratorium of payments, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated bankrupt or insolvent or to be granted a moratorium of payment, or the consent by the Company to the entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable bankruptcy, moratorium of payment, insolvency, reorganization or other similar law or to the commencement of any bankruptcy, moratorium of payment or insolvency proceedings against it, or the filing by it of a petition or consent seeking reorganization or similar relief under any applicable law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of substantially all of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action. SECTION 5.2. Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in Section 5.1(4) or (5)) occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities may declare the principal of all the Securities to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal and all accrued interest thereon shall become immediately due and payable. If an Event of Default specified in Section 5.1(4) or (5) occurs, the principal of, and accrued interest on, all the Securities shall ipso facto become immediately due and payable without any declaration or other Act of the Holders or any act on the part of the Trustee. At any time after such declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article Five provided, the Holders of a majority in aggregate principal amount 54 64 of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if (1) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue interest (including any Additional Amounts and Additional Interest) on all Securities, (B) the principal of and premium, if any, on any Securities which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate borne by the Securities, (C) to the extent that payment of such interest is lawful, interest upon overdue interest at a rate of 5% per annum, and (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (2) all Events of Default, other than the nonpayment of the principal of, and any interest on, Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. No rescission or annulment referred to above shall affect any subsequent default or impair any right consequent thereon. SECTION 5.3. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if (1) default is made in the payment of any interest (including any Additional Amounts and Additional Interest) on any Security when it becomes due and payable and such default continues for a period of 30 days, or (2) default is made in the payment of the principal of or premium, if any, on any Security at the Maturity thereof, the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and interest (including any Additional Amounts and Additional Interest) and interest on any overdue principal and premium, if any, and on any overdue interest (including any Additional Amounts and Additional Interest), to the extent permitted by law, at a rate of 5% per annum, 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. 55 65 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 or any other obligor upon the Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Securities, 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 5.4. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, moratorium of payments, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or the creditors of either, the Trustee (irrespective of whether the principal of, and any interest on, the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, (1) to file and prove a claim for the whole amount of principal, premium, if any, and interest owing and unpaid in respect of the Securities and take such other actions, including participating as a member, voting or otherwise, of any official committee of creditors appointed in such matter, and to file such other papers or documents, in each of the foregoing cases, 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 moneys 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 proceeding 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, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 6.7. 56 66 Nothing herein contained 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; provided, however, that the Trustee may, on behalf of such Holders, vote for the election of a trustee in bankruptcy or similar official. SECTION 5.5. Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which judgment has been recovered. SECTION 5.6. Application of Money Collected. Any money collected by the Trustee pursuant to this Article Five shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal, premium, if any, or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all amounts due the Trustee under Section 6.7; SECOND: To the payment of the amounts then due and unpaid for principal, premium, if any, or interest (including any Additional Amounts and Additional Interest) on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal, premium, if any, and interest (including any Additional Amounts and Additional Interest), respectively; and THIRD: Any remaining amounts shall be repaid to the Company. SECTION 5.7. Limitation on Suits. No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default; 57 67 (2) the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Outstanding Securities; it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders. SECTION 5.8. Unconditional Right of Holders to Receive Principal, Premium and Interest 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 of, premium, if any, and interest (including any Additional Amounts or Additional Interest) on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption or repurchase, on the Redemption Date or Repurchase Date, as the case may be), and to convert such Security in accordance with Article Twelve, and to institute suit for the enforcement of any such payment and right to convert, and such rights shall not be impaired without the consent of such Holder. SECTION 5.9. 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 such Holders shall continue as though no such proceeding had been instituted. 58 68 SECTION 5.10. 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 3.6, no right or remedy herein conferred 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 now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 5.11. 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 Five 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 (subject to the limitations contained in this Indenture) by the Holders of Securities. SECTION 5.12. Control by Holders of Securities. Subject to Section 6.3(5), the Holders of a majority in aggregate principal amount of the Outstanding Securities 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, provided that (1) such direction shall not be in conflict with any rule of law or with this Indenture; (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; (3) the Trustee need not take any action which might result in personal liability or be unjustly prejudicial to the Holders of Securities not consenting; and (4) such direction shall be presented by such Holders to the Trustee in a timely manner. SECTION 5.13. Waiver of Past Defaults. The Holders, either (a) through the written consent of not less than a majority in aggregate 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 the lesser of (x) not less than a majority in aggregate principal amount of Outstanding Securities and (y) at least 66-2/3% in aggregate principal amount of the Outstanding Securities 59 69 represented and entitled to vote at such meeting, may on behalf of the Holders of all the Securities waive any past default hereunder and its consequences, except a default (1) in the payment of the principal of, premium, if any, or interest on any Security, or (2) in respect of a covenant or provision hereof which under Article Eight cannot be modified or amended without the consent of the Holder 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; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. SECTION 5.14. Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Security by his or her 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. SECTION 5.15. Waiver of Stay, Extension and Usury 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 or take the benefit or advantage of, any stay, extension law or usury law or other law that would prohibit or forgive the Company from paying all or any portion of its obligations on the Securities as provided herein, 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 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 SIX THE TRUSTEE. SECTION 6.1. 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 and the Trust Indenture Act, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 60 70 (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; but 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 be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture, but not to verify the contents thereof. (b) In case a Responsible Officer of the Trustee has actual knowledge that an Event of Default 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 his or her 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; (2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and (3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in aggregate principal amount of the Outstanding Securities or such lesser percentage as provided in this Indenture relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture. (d) Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability has not been provided to it. 61 71 SECTION 6.2. Notice of Defaults. Within 90 days after the occurrence of any default hereunder as to which the Trustee has received written notice, the Trustee shall give to all Holders of Securities, in the manner provided in Section 1.6, notice of such default, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of, premium, if any, or interest on any Security, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders; and provided, further, that in the case of any default of the character specified in Section 5.1(4), no such notice to Holders of Securities shall be given until at least 30 days after the occurrence thereof. For the purpose of this Section, the term "default" means any event which is, or after notice or lapse of time or both would become, an Event of Default. SECTION 6.3. Certain Rights of Trustee. Subject to the provisions of Section 6.1: (1) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, Officers' Certificate, other certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; (2) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order (other than delivery of any Security to the Trustee for authentication and delivery pursuant to Section 3.1, which shall be sufficiently evidenced as provided therein), and any resolution of the Board shall be sufficiently evidenced by a Board Resolution; (3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers' Certificate; (4) the Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; (5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders of Securities, unless such Holders shall have offered to the Trustee 62 72 reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; (6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon, other evidence of indebtedness or other paper or document, but the Trustee in its sole discretion may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; (7) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; (8) the permissive right of the Trustee to take or refrain from taking any actions enumerated in this Indenture shall not be construed as a duty and the Trustee shall not be answerable in such actions other than for its own negligence, bad faith or willful misconduct in exercising any such right; and (9) the Trustee shall not be liable for any action taken, suffered or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by the Indenture. SECTION 6.4. Not Responsible for Recitals or Issuance of Securities. The recitals contained herein and in the Securities (except the Trustee's certificates of authentication) shall be taken as the statements of the Company, and the Trustee or any Authenticating Agent assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture, of the Securities or of the Common Stock issuable upon the conversion of the Securities. The Trustee or any Authenticating Agent shall not be accountable for the use or application by the Company of Securities or the proceeds thereof. SECTION 6.5. May Hold Securities, Act as Trustee Under Other Indentures. The Trustee, any Authenticating Agent, any Paying Agent, any Conversion Agent or any other agent of the Company or the Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company with the same rights it would have if it were not the Trustee, Authenticating Agent, Paying Agent, Conversion Agent or such other agent, subject to the Trust Indenture Act Sections 310(b) and 311. 63 73 The Trustee may become and act as trustee under other indentures under which other securities, or certificates of interest or participation in other securities, of the Company are outstanding in the same manner as if it were not Trustee hereunder. SECTION 6.6. Money Held in Trust. Money held by the Trustee in trust hereunder need 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 agreed in writing with the Company. SECTION 6.7. Compensation and Reimbursement. The Company agrees (1) to pay to the Trustee from time to time such reasonable compensation as the Company and the Trustee shall from time to time agree in writing for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except for any such expense, disbursement or advance as may be attributable to its negligence, bad faith or willful misconduct; and (3) to indemnify the Trustee (and its directors, officers, employees and agents) for, and to hold it harmless against, any loss, liability or expense incurred without negligence, bad faith or willful misconduct on its part, arising out of or in connection with the acceptance or administration of this trust, including the costs, expenses and reasonable attorneys' fees of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 5.1(4) or Section 5.1(5), the expenses (including the reasonable charges of its counsel) and the compensation for the services are intended to constitute expenses of the administration under any applicable Federal or state bankruptcy, insolvency or other similar law. Any Paying Agent or Authenticating Agent appointed hereunder shall be entitled to the benefits of Section 6.7(3) as if the indemnity set forth therefor were specifically afforded to such Paying Agent or Authenticating Agent. 64 74 The provisions of this Section shall survive the termination of this Indenture or the earlier resignation or removal of the Trustee, any Paying Agent or any Authenticating Agent, as the case may be. The obligations of the Company under this Section to compensate the Trustee, to pay or reimburse the Trustee for expenses, disbursements and advances and to indemnify and hold harmless the Trustee shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. As security for the performance of such obligations of the Company, the Trustee shall have a claim prior to the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of (and premium, if any) or interest on particular Securities. SECTION 6.8. Corporate Trustee Required; Eligibility. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, having (or if the Trustee is a member of a bank holding company, its bank holding company having) a combined capital and surplus of at least U.S.$50,000,000, subject to supervision or examination by Federal or state authority, in good standing. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article and a successor shall be appointed pursuant to Section 6.9. SECTION 6.9. Resignation and Removal; Appointment of Successor. (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.10. (b) The Trustee may resign at any time by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.10 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee. (c) The Trustee may be removed at any time by Act of the Holders of a majority in aggregate principal amount of the Outstanding Securities, delivered to the Trustee and the Company. If the instrument of acceptance by a successor Trustee required by Section 6.10 shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the removed Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee. (d) If at any time: 65 75 (1) the Trustee shall cease to be eligible under Section 6.8 and shall fail to resign after written request therefor by the Company or by any Holder of a Security who has been a bona fide Holder of a Security for at least six months, or (2) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case (i) the Company by a Board Resolution may remove the Trustee, or (ii) subject to Section 5.14, any Holder of a Security who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Company, by a Board Resolution, shall promptly appoint a successor Trustee and shall comply with the applicable requirements of this Section and Section 6.10. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in aggregate principal amount of the Outstanding Securities delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.10, become the successor Trustee and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders of Securities and accepted appointment in the manner required by this Section and Section 6.10, any Holder of a Security who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. (f) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders of Securities in the manner provided in Section 1.6. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. SECTION 6.10. Acceptance of Appointment by Successor. Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, 66 76 the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be eligible under this Article. SECTION 6.11. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. SECTION 6.12. Authenticating Agents. The Trustee may appoint an additional Authenticating Agent or Agents with respect to the Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities issued upon exchange or substitution pursuant to this Indenture. Securities authenticated by an Authenticating Agent shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder, and every reference in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Appointment of each Authenticating Agent shall be subject to acceptance by the Company, and each Authenticating Agent shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, or Luxembourg, authorized under such laws to act as Authenticating Agent and subject to supervision or examination by government or other fiscal authority. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 6.12, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section 6.12. Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible 67 77 under this Section 6.12, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 6.12, the Trustee may appoint a successor Authenticating Agent which shall be subject to acceptance by the Company. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section 6.12. The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section 6.12 and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 6.7. If an Authenticating Agent is appointed with respect to the Securities pursuant to this Section 6.12, the Securities may have endorsed thereon, in addition to or in lieu of the Trustee's certification of authentication, an alternative certificate of authentication in the following form: This is one of the Securities referred to in the within-mentioned Indenture. Dated: DEUTSCHE BANK AG, NEW YORK BRANCH, as Trustee By [Authenticating Agent], as Authenticating Agent By: ______________________________________ Authorized Signatory SECTION 6.13. Disqualification; Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. SECTION 6.14. Preferential Collection of Claims Against Company. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of Section 311 of 68 78 the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). ARTICLE SEVEN CONSOLIDATION, MERGER, TRANSFER OR LEASE SECTION 7.1. Company May Consolidate, Etc., Only on Certain Terms. The Company shall not consolidate with or merge into any other Person or convey or transfer or lease its properties and assets substantially as an entirety to any Person (other than to a wholly-owned subsidiary), and shall not transfer and assign all its obligations of, and position as, the Company hereunder, except for a consolidation or merger in which the Company is the surviving party, unless: (a) the Person formed by such consolidation or into which the Company is merged or which acquires by conveyance or transfer the properties and assets of the Company substantially as an entirety, or to which obligations of, and position as, the Company hereunder are transferred and assigned (the "Successor") (i) shall be a corporation, limited liability company, partnership or trust organized and existing under the laws of, and resident for tax purposes in, the United States of America or any political subdivision thereof, and (ii) shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, due and punctual payment of the principal of, premium, if any, and interest (including Additional Amounts, if any, and Additional Interest, if any) on all of the Securities and the performance of every covenant of this Indenture and in the Securities on the part of the Company to be performed or observed; (b) immediately after giving effect to any such consolidation, merger, conveyance or transfer, or such transfer and assignment, no default and no Event of Default shall have occurred and be continuing; and (c) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance or transfer, or such transfer and assignment, and such supplemental indenture comply with this Article and that all conditions precedent herein provided for relating to such transaction have been compiled with. SECTION 7.2. Successor Substituted. Upon any consolidation, merger or any conveyance or transfer of the properties and assets of the Company substantially as an entirety, or upon transfer and assignment of all obligations of, and position as, the Company hereunder, in accordance with Section 7.1, the Successor shall succeed to and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such Successor had been named as the 69 79 Company herein, and thereafter, the predecessor Person shall be relieved of all obligations and covenants under the Indenture and the Securities. ARTICLE EIGHT SUPPLEMENTAL INDENTURES SECTION 8.1. Supplemental Indentures Without Consent of Holders of Securities.

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Sections 6.1 and 6.3) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture, and that such supplemental indenture has been duly authorized, executed and delivered by the Company and constitutes a valid and legally binding obligation of the Company enforceable against the Company in accordance with its terms.

SECTION 10.3. Money for Security Payments To Be Held in Trust. If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal of, premium, if any, or interest (including any Additional Amount or Additional Interest) on any of the Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal, premium, if any, or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and the Company will promptly notify the Trustee of its action or failure so to act. Whenever the Company shall have appointed one or more Paying Agents, it will, on or prior to each due date of the principal of, premium, if any, or interest on any Securities, deposit with such Paying Agents a sum sufficient to pay the principal, premium, if any, or interest so becoming due, such sum to be held for the benefit of the Persons entitled to such principal, premium, if any, or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or any failure so to act. The Company will cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: (1) hold all sums held by it for the payment of the principal of, premium, if any, or interest on Securities for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities) in the making of any payment of principal, premium, if any, or interest; and 77 87 (3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held by such Paying Agent. The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Security and remaining unclaimed at the earlier of the date which is 10 days prior to the date such money would escheat to the state or two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease. SECTION 10.4. Additional Amounts. The Company will pay to a Non-U.S. Holder of any Security Additional Amounts as provided in the form of Security, as set forth in Section 2.2.

If any withholding or deduction shall be required, an Officers' Certificate shall specify the amount required to be withheld or deducted with respect to such payments to such Holders of Securities and the Company will pay to the Trustee or the applicable Paying Agent the Additional Amounts, if any, required to be paid as set forth in the first sentence of this 78 88 Section 10.4. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence, bad faith or willful misconduct arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers' Certificate furnished or not furnished pursuant to this Section.

If the officer or officers signing the Officers' Certificate know of such a default, whether then existing or occurring during such preceding fiscal year, the Officers' Certificate shall describe such default and its status with particularity. The Company shall also promptly notify the Trustee if the Company's fiscal year is changed so that the end thereof is on any date other than the then current fiscal year end date. The Company will deliver to the Trustee, promptly upon becoming aware of any default in the performance or observance of any covenant, agreement or condition contained in this Indenture, or any Event of Default, an Officers' Certificate specifying with particularity such default or Event of Default and further stating what action the Company has taken, is taking or proposes to take with respect thereto. Any notice required to be given under this Section 10.6 shall be delivered to the Trustee at its Corporate Trust Office. SECTION 10.7. Delivery of Certain Information.

"Rule 144A Information" shall be such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act (or any successor provision thereto). SECTION 10.8. Additional Interest. The Company will pay Additional Interest as provided in the Registration Rights Agreement. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of, premium, if any, or interest on, or in respect of, any Security, such mention shall be deemed to include mention of the payment of Additional Interest provided for in the Registration Rights Agreement to the extent that, in such context, Additional Interest is, was or would be payable in respect thereof pursuant to the provisions of the Registration Rights Agreement and express mention of the payment of Additional Interest (if applicable) in any provisions hereof shall not be construed as excluding Additional Interest in those provisions hereof where such express mention is not made.

SECTION 11.2. Applicability of Article.

In case of any redemption at the election of the Company of any of the Securities, the Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date.

SECTION 11.4. Selection by Trustee of Securities to Be Redeemed. If less than all the Securities are to be redeemed (other than pursuant to the third paragraph on the reverse of the form of Security in Section 2.2), the particular Securities to be redeemed shall be selected by the Trustee within seven Business Days after it receives the notice described in 11.3, from the Outstanding Securities not previously called for redemption, by lot or such method as the Trustee may deem fair and appropriate. If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection. The Trustee shall promptly notify the Company and each Security 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. 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 11.5. Notice of Redemption. Notice of redemption shall be given in the manner provided in Section 1.6 to the Holders of Securities to be redeemed not less than 20 nor more than 60 days prior to the Redemption Date, and such notice shall be irrevocable. All notices of redemption shall state: (1) the Redemption Date, (2) the Redemption Price, (3) if less than all Outstanding Securities are to be redeemed, the aggregate principal amount of Securities to be redeemed and the aggregate principal amount of Securities which will be outstanding after such partial redemption, 81 91 (4) that on the Redemption Date the Redemption Price, and accrued interest, if any, will become due and payable upon each such Security to be redeemed, and that interest thereon shall cease to accrue on and after said date, (5) the Conversion Price then in effect, the date on which the right to convert 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 interest, if any, and (7) in the case of a notice of redemption pursuant to the third paragraph on the reverse of the form of Security in Section 2.2, a form of written certification of each beneficial owner of a Security as to such beneficial owner's entitlement to Additional Amounts. In case of a partial redemption, the notice shall specify the serial and CUSIP numbers (if any) and the portions thereof called for redemption and that transfers and exchanges may occur on or prior to the Redemption Date. 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 request, by the Trustee in the name of and at the expense of the Company. Notice of redemption of Securities to be redeemed at the election of the Company received by the Trustee shall be given by the Trustee to each Paying Agent in the name of and at the expense of the Company. So long as the Securities are listed on the Luxembourg Stock Exchange and the rules of the Luxembourg Stock Exchange shall require, notice of redemption will be given by publication in an Authorized Newspaper in Luxembourg, or, if not practicable in Luxembourg, elsewhere in a Western European city. SECTION 11.6. Deposit of Redemption Price. By 10:00 a.m. (New York time) on any Redemption Date of the Securities, the Company shall deposit with the Trustee or with the Paying Agent so directed by the Trustee (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3) an amount of money (which shall be in immediately available funds on such Redemption Date) sufficient to pay the Redemption Price of, and accrued interest on, all the Securities which are to be redeemed on that date other than any Securities called for redemption on that date which have been converted prior to the date of such deposit. 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, if a Security, or any Predecessor Security to receive interest as provided in the last paragraph of Section 3.7) be paid to the Company on Company Request as soon as administratively practicable after the Trustee 82 92 receives such Company Request or, if then held by the Company, shall be discharged from such trust. SECTION 11.7. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified and from and after such date (unless the Company shall default in the payment of the Redemption Price, including accrued interest) such Securities shall cease to bear interest. Upon surrender of any Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price together with accrued and unpaid interest to the Redemption Date; provided, however, that installments of interest on Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Record Date according to their terms and the provisions of Section 3.7. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal amount of, premium, if any, and, to the extent permitted by applicable law, accrued interest on such Security shall, until paid, bear interest from the Redemption Date at a rate of 5% per annum and such Security shall remain convertible into Common Stock until the principal of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for. SECTION 11.8. 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 10.2 (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 his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. SECTION 11.9. Conversion Arrangement on Call for Redemption. In connection with any redemption of Securities, the Company may arrange for the purchase and conversion of any Securities by an agreement with one or more investment bankers or other purchasers (the "Purchasers") to purchase such securities by paying to the Trustee in trust for the Holders, on or before the Redemption Date, an amount not less than the applicable Redemption Price, together with interest accrued to the Redemption Date, of such Securities. Notwithstanding anything to the contrary contained in this Article Eleven, the obligation of the Company to pay the Redemption Price, together with interest accrued to, but excluding, the Redemption Date, shall be deemed to be satisfied and discharged to the extent such amount is so paid by such Purchasers. If such an agreement is entered into (a copy of which 83 93 shall be filed with the Trustee prior to the close of business on the Business Day immediately prior to the Redemption Date), any Securities called for redemption that are not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, and consistent with any agreement or agreements with such Purchasers, to be acquired by such Purchasers from such Holders and (notwithstanding anything to the contrary contained in Article Twelve) surrendered by such Purchasers for conversion, all as of immediately prior to the close of business on the Redemption Date (and the right to convert any such Securities shall be extended though such time), subject to payment of the above amount as aforesaid. At the direction of the Company, the Trustee shall hold and dispose of any such amount paid to it to the Holders in the same manner as it would monies deposited with it by the Company for the redemption of Securities. Without the Trustee's prior written consent, no arrangement between the Company and such Purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and the Company agrees to indemnify the Trustee from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Securities between the Company and such Purchasers, including the costs and expenses, including reasonable legal fees, incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture. ARTICLE TWELVE CONVERSION OF SECURITIES SECTION 12.1. Conversion Privilege and Conversion Price. Subject to and upon compliance with the provisions of this Article Twelve, at the option of the Holder thereof, the Holder of any Security is entitled, at any time prior to the close of business on the Business Day immediately preceding October 1, 2002, to convert such Security into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock at the Conversion Price, determined as hereinafter provided, in effect at the time of conversion. Such conversion right shall be subject, in the case of the conversion of any Global Security, to any applicable book-entry procedures of the Depositary therefor and the following sentence. In case a Security or portion thereof is called for redemption or is delivered for repurchase, such conversion right in respect of the Security or portion so called shall expire at the close of business on the Business Day prior to the Redemption Date or the Repurchase Date (as defined in Article Fourteen), as the case may be, unless the Company defaults in making the payment due upon redemption or repurchase, as the case may be. The price at which shares of Common Stock shall be delivered upon conversion (herein called the "Conversion Price") shall be initially U.S.$28.00 per share of Common Stock. The Conversion Price shall be adjusted in certain instances as provided in this Article Twelve. 84 94 SECTION 12.2. Exercise of Conversion Privilege. Beneficial owners of interests in a Global Security may exercise their right of conversion by delivering to the Depositary the appropriate instruction form for conversion pursuant to the Depositary's conversion program and, in the case of conversions through Euroclear or Cedel, in accordance with Euroclear's or Cedel's normal operating procedures. To convert a Certificated Security into shares of Common Stock, a Holder must (i) complete and manually sign the conversion notice in the form set forth in Section 2.4 on the back of the Certificated Security (or complete and manually sign a facsimile thereof) and deliver such notice to the office of a Conversion Agent, (ii) surrender the Certificated Security to such Conversion Agent, (iii) if required, furnish appropriate endorsements and transfer documents, (iv) if required, pay all transfer or similar taxes, and (v) if required, pay funds equal to interest payable on the next Interest Payment Date. The date on which all of the foregoing requirements have been satisfied is the date of surrender for conversion. Notes surrendered for conversion, in whole or in part, shall be forwarded promptly by the Conversion Agent to the Trustee for cancellation. The Company shall execute and the Trustee shall authenticate and deliver a new Security or Securities in principal equal to the unconverted portion of Notes so surrendered. The Conversion Agent will deliver promptly to the Paying Agent in New York, New York all funds collected representing interest payable on a Security converted when required pursuant hereto. The Trustee shall promptly deliver to the Company and the Company's Common Stock transfer agent notification of such notice of conversion at the address described in Section 1.5. Such notice of conversion can be obtained from the Trustee at the Corporate Trust Office or the office of any Conversion Agent. Each Security, or beneficial interest therein, surrendered for conversion will be converted into Common Stock in registered form. Each Security, or beneficial interest therein, surrendered for conversion (in whole or in part) 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 shall be accompanied by payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of such Security (or part thereof, as the case may be) being surrendered for conversion. The interest so payable on such Interest Payment Date in respect of any Security (or portion thereof, as the case may be), which Security (or portion thereof, as the case may be) is surrendered for conversion during such period, shall be paid to the Holder of such Security as of such Regular Record Date. No cash payment or adjustment shall be made on conversion of a Security for interest accrued thereon from the Interest Payment Date next preceding the date of conversion or for dividends on the Common Stock issued on conversion thereof subject only (i), in the case of a conversion after the close of business on any Regular Record Date and prior to the next succeeding Interest Payment Date, to the obligation of the Holder to pay to the Company an amount equal to the accrued interest in respect of such Security as provided in Section 2.2 and the obligation of the Company to pay such accrued interest to the Holder of such Security (or any Predecessor Security) of record on the Regular Record Date next preceding such Interest Payment Date and (ii) in the case of a conversion on an Interest Payment Date, the obligation of 85 95 the Company to pay to the Holder of such Security (or any Predecessor Security) of record on the Regular Record Date next preceding such Interest Payment Date interest accrued thereon from such next preceding Interest Payment Date. The Company's delivery to the Holder of the number of shares of Common Stock (and cash in lieu of fractions thereof, as provided in this Indenture) into which a Security is convertible will be deemed to satisfy the Company's obligation to pay the principal amount of the Security. 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 Common Stock at such time. As promptly as practicable on or after the conversion date, the Company shall issue and deliver to the Trustee, for delivery to the Holder, a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any fraction of a share, as provided in Section 12.3. All shares of Common Stock delivered upon such conversion of Securities that are Restricted Securities shall, if required, bear a restricted securities legend, substantially to the same effect as the Restricted Securities Legends, and shall be subject to the restrictions on transfer provided in such legend. Neither the Trustee nor any agent maintained for the purpose of such conversion shall have any responsibility for the inclusion or content of any such restricted securities legends on such shares of Common Stock; provided, however, that the Trustee or Conversion Agent shall have provided, to the Company or to the Security Registrar for such shares of Common Stock, prior to or concurrently with a request to the Company to deliver such shares of Common Stock, written notice that the Securities delivered for conversion are Restricted Securities. In the case of any Security which is converted in part only, 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 an aggregate principal amount equal to the unconverted portion of the principal amount of such Security. A Security may be converted in part, but only if the principal amount of such Security to be converted is any integral multiple of U.S.$1,000 and the principal amount of such security to remain Outstanding after such conversion is equal to U.S.$1,000 or any integral multiple thereof. SECTION 12.3. Fractions of Shares. No fractional shares of Common Stock shall be issued upon conversion of any Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock which would 86 96 otherwise be issuable upon conversion of any Securities (or specified portions thereof), the Company shall calculate and pay a cash adjustment in respect of such fraction (calculated to the nearest 1/100th of a share) in an amount equal to the same fraction of the Current Market Price per share of Common Stock (calculated in accordance with Section 12.4(7)(b) below) at the close of business on the day of conversion. SECTION 12.4. Adjustment of Conversion Price. The Conversion Price shall be subject to adjustments from time to time as follows: (1) 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, the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and 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 to become effective immediately after the opening of business on the day following the date fixed for such determination. If any dividend or distribution of the type described in this Section 12.4(1) 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. (2) In case the Company shall issue rights or warrants to all holders of its outstanding Common Stock entitling them (for a period expiring within 45 days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase Common Stock at a price per share less than the Current Market Price (as defined in Section 12.4(7)(b)) on the date fixed for 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 immediately prior to the date fixed for determination of shareholders entitled to receive such rights or warrants by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights and warrants plus the number of shares which the aggregate exercise price of the total number of shares so offered would purchase at such Current Market Price, and the denominator of which shall be the number of shares of Common Stock outstanding on the date fixed for determination of stockholders entitled to receive such rights and warrants plus the total number of additional shares of Common Stock offered for subscription or purchase. Such adjustment shall be successively made whenever any such rights and warrants are issued, and shall become effective immediately after the opening of business on the day following the date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such 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 delivery of only the 87 97 number of shares of 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 exercise price of such Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants, the value of such consideration, if other than cash, to be determined by the Board of Directors. (3) In case outstanding 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 so that the Holder of Securities thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock that such Holder would have been entitled to receive immediately following such subdivision had such Securities been converted immediately prior thereto, 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. (4) 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(1) applies) or evidences of its indebtedness or assets (including securities, but excluding any rights or warrants referred to in Section 12.4(2), and excluding any dividend or distribution (x) paid exclusively in cash or (y) referred to in Section 12.4(1) (any of the foregoing hereinafter in this Section 12.4(4) called the "Distribution Securities")), then, in each such case, the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect on the Distribution Record Date with respect to such distribution by a fraction the numerator of which shall be the Current Market Price per share of Common Stock on such Distribution Record Date less the fair market value (as determined by the Board of Directors whose determination shall be conclusive and described in a resolution of the Board of Directors) on the Distribution Record Date of the portion of the Distribution Securities so distributed applicable to one share of outstanding Common Stock and the denominator of which shall be the Current Market Price per share of outstanding Common Stock, such reduction to become effective immediately prior to the opening of business on the day following such Distribution Record Date; provided, however, that in the event the then fair market value (as so determined) of the portion of the Distribution Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price per share of the Common Stock on the Distribution 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 the amount of Distribution Securities such Holder would have received had such Holder converted each Security on the Distribution 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. If the Company's Board of Directors determines the fair market value of 88 98 any distribution for purposes of this Section 12.4(4) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price of the Common Stock. In the event that the Company implements a stockholder rights plan, such rights plan shall provide that upon conversion of the Securities the Holders will receive, in addition to the Common Stock issuable upon such conversion, the rights issued under such rights plan (notwithstanding the occurrence of an event causing such rights to separate from the Common Stock at or prior to the time of conversion). Any distribution of rights or warrants pursuant to a stockholder rights plan complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights or warrants for the purposes of this Section 12.4. 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 under certain circumstances), which rights or warrants, until the occurrence of a specified event or events ("Trigger Event"): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of shares of Common Stock, shall be deemed not to have been distributed for purposes of this Section 12.4 (and no adjustment to the Conversion Price under this Section 12.4 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Price shall be made under this Section 12.4(4). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, 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 was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Price under this Section 12.4 was made, (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of shares of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of shares of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Price shall be readjusted as if such rights and warrants had not been issued. Notwithstanding the foregoing, in the event that the Company shall distribute rights or warrants to subscribe for additional shares of the Common Stock (other than rights or 89 99 warrants described in Section 12.4(2)), pro rata to holders of Common Stock, the Company may, in lieu of making any adjustment pursuant to this Section 12.4(4), make proper provision so that each holder of a Security who converts such Security (or any portion thereof) after the Distribution Record Date for such distribution and prior to the expiration or redemption of such rights or warrants shall be entitled to receive upon such conversion, in addition to the shares of Common Stock issuable upon such conversion (the "Conversion Shares"), a number of rights or warrants to be determined as follows: (i) if such conversion occurs on or prior to the date for the distribution to the holders of such rights or warrants of separate certificates evidencing such rights or warrants (the "Distribution Date"), the same number of rights or warrants to which a holder of a number of shares of Common Stock equal to the number of Conversion Shares is entitled at the time of such conversion in accordance with the terms and provisions of and applicable to such rights or warrants; and (ii) if such conversion occurs after the Distribution Date, the same number of rights or warrants to which a holder of the number of shares of Common Stock into which the principal amount of the Security so converted was convertible immediately prior to the Distribution Date would have been entitled on the Distribution Date in accordance with the terms and provisions of, and applicable to such rights or warrants. For purposes of this Section 12.4(4) and Sections 12.4(1) and (2), any dividend or distribution to which this Section 12.4(4) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights or warrants (and any Conversion Price reduction required by this Section 12.4(4) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Price reduction required by Sections 12.4(1) and (2) with respect to such dividend or distribution shall then be made), except (A) the Distribution Record Date of such dividend or distribution shall be substituted as "the date fixed for the determination of shareholders entitled to receive such dividend or other distribution" and "the date fixed for such determination" within the meaning of Sections 12.4(1) and (2) and (B) 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(1). (5) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding (w) any quarterly cash dividend on the Common Stock to the extent the aggregate cash dividend per share of Common Stock in any quarterly period does not exceed the greater of (A) the amount per share of Common Stock of the next preceding quarterly cash dividend on the Common Stock to the extent that such preceding quarterly dividend did not require any adjustment of the Conversion Price pursuant to this Section 12.4(5) (as adjusted to reflect subdivisions or combinations of the Common Stock), and (B) 7.00% of the arithmetic average of the Closing Prices (determined as set forth in Section 12.4(7)(a)) during the ten Trading Days immediately prior to the date of declaration of such dividend, (x) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, (y) any cash that is distributed as part of a distribution requiring a Conversion Price adjustment pursuant to Section 12.4(4) and (z) any cash distribution 90 100 upon a merger or consolidation to which Section 12.11 hereof applies), then, in such case, 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 Distribution Record Date by a fraction of which the numerator shall be the Current Market Price of the Common Stock on the Distribution Record Date less the amount of cash so distributed (and not excluded as provided above) applicable to one share of outstanding Common Stock and the denominator shall be such Current Market Price of the Common Stock on the Distribution Record Date, such reduction to be effective immediately prior to the opening of business on the day following the Distribution Record Date; provided, however, that in the event the portion of the cash so distributed applicable to one share of outstanding Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Distribution 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 the amount of cash such Holder would have received had such Holder converted each Security on the Distribution 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. If any adjustment is required to be made as set forth in this Section 12.4(5) as a result of a distribution that is a quarterly dividend, such adjustment shall be based upon the amount by which such distribution exceeds the amount of the quarterly cash dividend permitted to be excluded pursuant hereto. If an adjustment is required to be made as set forth in this Section 12.4(5) above as a result of a distribution that is not a quarterly dividend, such adjustment shall be based upon the full amount of the distribution. (6) In case a tender or exchange offer made by the Company or any subsidiary of the Company for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) that as of the last time (the "Expiration Time") tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Current Market Price per share of the Common Stock on the Trading Day next succeeding the Expiration Time, 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 Expiration Time by a fraction of which the numerator shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) on the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time and 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 or exchange offer) of all shares validly tendered or exchanged 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 to 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 91 101 purchase shares pursuant to any such tender or exchange 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 or exchange offer had not been made. (7) For purposes of this Section 12.4, the following terms shall have the meaning indicated: (a) "Closing Price" with respect to any securities on any day shall mean the closing sale price regular way on such day or, in case no such sale takes place on such day, the average of the reported closing bid and asked prices, regular way, in each case on the New York Stock Exchange, or, if such security is not listed or admitted to trading on such Exchange, on the principal security exchange or quotation system in the United States on which such security is quoted or listed or admitted to trading, or, the average of the closing bid and asked prices of such security on the over-the-counter market on the day in question as reported by the Nasdaq National Market or a similar generally accepted reporting service, or if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to time by the Board of Directors for that purpose, or a price determined in good faith by the Board of Directors or, to the extent permitted by applicable law, a duly authorized committee thereof, whose determination shall be conclusive. (b) "Current Market Price" shall mean the average of the daily Closing Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to the date in question; provided, however, that (1) if the "ex" date (as hereinafter defined) for any event (other than the issuance or distribution or Fundamental Change requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(1), (2), (3), (4), (5) or (6) occurs during such ten consecutive Trading Days, the Closing Price for each Trading Day prior to the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event, (2) if the "ex" date for any event (other than the issuance, distribution or Fundamental Change requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(1), (2), (3), (4), (5) or (6) occurs on or after the "ex" date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing 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 (3) if the "ex" date for the issuance, distribution or Fundamental Change requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Closing Price for each Trading Day on or after such "ex" date shall be adjusted by adding thereto the amount of any cash 92 102 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(4) or (6), whose determination shall be conclusive and described in a resolution of the Board of Directors) 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(6), the Current Market Price of the Common Stock on any date shall be deemed to be the average of the daily Closing 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 or exchange offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(1), (2), (3), (4), (5) or (6) occurs on or after the Expiration Time or Tender Expiration Time, as the case may be, for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing 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, (1) when used 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 Closing Price was obtained without the right to receive such issuance or distribution, (2) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and (3) when used 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 or Tender Expiration Time, as the case may be, of such offer. (c) "fair market value" shall mean the amount which a willing buyer would pay a willing seller in an arm's length transaction. (d) "Distribution 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). (e) "Trading Day" shall mean (x) if the applicable security is listed or admitted for trading on the New York Stock Exchange or another national security exchange, a day on which the New York Stock Exchange or another 93 103 national security exchange is open for business or (y) if the applicable security is quoted on the Nasdaq National Market, a day on which trades may be made on thereon or (z) if the applicable security is not so listed, admitted for trading or quoted, any day other than a Saturday or Sunday or a day on which banking institutions in the State of New York are authorized or obligated by law or executive order to close. (8) Notwithstanding anything to the contrary contained herein, no adjustment in the Conversion Price shall be required unless such adjustment (plus any adjustments not previously made by reason of this paragraph (8)) would require an increase or decrease of at least one percent in such price; provided, however, that any adjustments which by reason of this paragraph (8) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. (9) The Company may, at its option, make such reductions in the Conversion Price as the Board deems advisable, in addition to those required by paragraphs (1), (2), (3), (4), (5) or (6) of this Section 12.4, in order to avoid or diminish any income tax to any holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution on Common Stock (or rights to acquire such shares) or from any event treated as such for income tax purposes or resulting from any dividend or distribution of shares or issuance of rights or warrants to purchase or subscribe for shares or from any event treated as such for income tax purposes. 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 (i) the period is at least twenty (20) days, (ii) the reduction is irrevocable during the period and (iii) the Board shall have made a determination that such reduction would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall give notice of the reduction to the Holders of Securities in the manner provided in Section 1.6 at least fifteen (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. (10) No adjustment of the Conversion Price will result in zero or a negative number. SECTION 12.5. Notice of Adjustments of Conversion Price. Whenever the Conversion Price is adjusted as herein provided: (1) the Company shall compute the adjusted Conversion Price in accordance with Section 12.4 and shall prepare a certificate signed by the President, Treasurer, Chief Financial Officer or Vice President of Finance of the Company setting forth the adjusted Conversion Price and showing in reasonable 94 104 detail the facts upon which such adjustment is based, and such certificate shall promptly be filed with the Trustee and with each Conversion Agent; and (2) a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall promptly be prepared and as soon as practicable thereafter, such notice shall be provided by the Company to all Holders in accordance with Section 1.6. Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate or the information and calculations contained therein, except to exhibit the same to any Holder of Securities desiring inspection thereof at its office during normal business hours. So long as the Securities are listed on the Luxembourg Stock Exchange and the rules of the Luxembourg Stock Exchange shall so require, notice of any adjustment of the Conversion Price pursuant to this Article Twelve will be given by publication in an Authorized Newspaper in Luxembourg, or, if not practicable in Luxembourg, elsewhere in a Western European city. Any failure of the Company to give such notice, or any defect therein, shall not in any way impair or affect the validity of any such Conversion Price adjustment. SECTION 12.6. Notice of Certain Corporate Action. In case: (a) the Company shall declare a dividend (or any other distribution) on all or substantially all of its Common Stock payable (i) otherwise than exclusively in cash or (ii) exclusively in cash in an amount that would require any adjustment pursuant to Section 12.4; or (b) the Company shall authorize the granting to the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights that would require any adjustment pursuant to Section 12.4; or (c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or (e) the Company or any subsidiary of the Company shall commence a tender offer for all or a portion of the Company's outstanding Common Stock (or shall amend any such tender offer); 95 105 then the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 10.2, and shall cause to be provided to all Holders in accordance with Section 1.6, at least 20 days (or 10 days in any case specified in clause (a) or (b) above) prior to the applicable record, expiration or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights, options or warrants are to be determined, (y) the date on which the right to make tenders under such tender offer expires or (z) the date on which such reclassification, consolidation, merger, share exchange, conveyance, transfer, sale, 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, consolidation, merger, share exchange, conveyance, transfer, sale, lease, dissolution, liquidation or winding up. If at the time the Trustee shall not be the Conversion Agent, a copy of such notice and any notice referred to in the following paragraph shall also forthwith be filed by the Company with the Trustee. The preceding paragraph to the contrary notwithstanding, the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 10.2, and shall cause to be provided to all Holders in accordance with Section 1.6, notice of any tender offer by the Company or any subsidiary of the Company for all or any portion of the Common Stock at or about the time that such notice of tender offer is provided to the public generally (such notice to be sent to all Holders within five days after receipt of such notice by the Trustee or Conversion Agent from the Company). SECTION 12.7. Company to Provide Common Stock. The Company shall ensure that the Company has, free from preemptive rights, out of its authorized but unissued Common Stock, the full number of shares of Common Stock for the purpose of effecting the conversion of Securities. SECTION 12.8. Taxes on Conversions. The Company will pay any and all documentary, stamp or similar duties to the United States of America or any political subdivision or taxing authority thereof or therein that may be payable in respect of the issue or delivery of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue and delivery 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 and until 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. The Company extends no protection with respect to any other taxes imposed in connection with the conversion of Securities. 96 106 SECTION 12.9. Company Covenant as to Common Stock. The Company covenants that all Common Stock that may be delivered upon conversion of Securities, upon such delivery, will have been duly authorized and validly issued and will be fully paid and nonassessable and, except as provided in Section 12.8, the Company will pay all taxes, liens and charges with respect to the issue thereof. SECTION 12.10. Cancellation of Converted Securities. All Securities delivered for conversion shall be delivered to the Trustee or the Paying Agent in Luxembourg or its agent to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 3.9. SECTION 12.11. Provision in Case of Consolidation, Merger, or Sale of Assets of the Company. In case of any consolidation of the Company with, or merger of the Company into, any other Person, or any merger of another Person into the Company (other than a merger which does not result in any reclassification, conversion, exchange or cancellation of outstanding Common Stock of the Company) or any sale or transfer of all or substantially all of the assets of the Company, the Company and the Person formed by such consolidation or resulting from such merger or which acquires such assets shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then Outstanding shall have the right thereafter, during the period such Security shall be convertible as specified in Section 12.1, to convert such Security only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer by a holder of the number of shares of Common Stock of the Company into which such Security might have been converted immediately prior to such consolidation, merger, sale or transfer, assuming such holder of Common Stock of the Company (i) is not a Person with which the Company consolidated or into which the Company merged or which merged into the Company or to which such sale or transfer was made, as the case may be (a "Constituent Person"), or an Affiliate of a Constituent Person, and (ii) failed to exercise his rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer (provided that if the kind or amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer is not the same for each share of Common Stock of the Company held immediately prior to such consolidation, merger, sale or transfer by others than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised ("Non-electing Share"), then for the purposes of this Section 12.11 the kind and amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer by the holders of each Non-electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-electing Shares). Such supplemental indenture shall provide for adjustments which, for events subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article. The above provisions of this Section 12.11 shall similarly apply to successive consolidations, mergers, sales or transfers. Notice of the execution of such a 97 107 supplemental indenture shall be given by the Company to the Holder of each Security as provided in Section 1.6 promptly upon such execution. Neither the Trustee, any Paying Agent nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any such supplemental indenture relating either to the kind or amount of shares of stock or other securities or property or cash receivable by Holders of Securities upon the conversion of their Securities after any such consolidation, merger, conveyance, transfer, sale or lease or to any such adjustment, but may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an Opinion of Counsel with respect thereto, which the Company shall cause to be furnished to the Trustee upon request. SECTION 12.12. Responsibility of Trustee for Conversion Provisions. The Trustee, subject to the provisions of Section 6.1, 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 extent of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same, or whether a supplemental indenture need be entered into. Neither the Trustee, subject to the provisions of Section 6.1, nor any Conversion Agent shall be accountable with respect to the validity or value (or the kind or amount) of any Common Stock, or of any other securities or property or cash, 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 6.1, nor any Conversion Agent shall be responsible for any failure of the Company to make or calculate any cash payment or to issue, transfer or deliver any Common Stock or share certificates or other securities or property or cash upon the surrender of any Security for the purpose of conversion; and the Trustee, subject to the provisions of Section 6.1, and any Conversion Agent shall not be responsible for any failure of the Company to comply with any of the covenants of the Company contained in this Article. ARTICLE THIRTEEN SUBORDINATION OF SECURITIES SECTION 13.1. Agreement of Subordination. The Company covenants and agrees, and each Holder of Securities issued hereunder by his acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject to the provisions of this Article Thirteen; and each Person holding any Security, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees to be bound by such provisions. The payment of the principal of, premium, if any, and interest on all Securities (including, but not limited to, the Redemption Price with respect to the Securities called for redemption in accordance with Article Eleven, or the Repurchase Price with respect to Securities 98 108 submitted for repurchase in accordance with Article Fourteen, as the case may be, as provided in this Indenture and Additional Amounts, if any, and Additional Interest, if any) issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full in cash of all Senior Indebtedness of the Company, whether outstanding at the date of this Indenture or thereafter incurred, created, assumed or guaranteed, and that these subordination provisions are for the benefit of the holders of Senior Indebtedness. No provision of this Article Thirteen shall prevent the occurrence of any default or Event of Default hereunder. SECTION 13.2. Payments to Holders. No payment shall be made with respect to the principal of, or premium, if any, or interest on the Securities by the Company (including, but not limited to, the Redemption Price with respect to the Securities to be called for redemption in accordance with Article Eleven or the Repurchase Price with respect to Securities submitted for repurchase in accordance with Article Fourteen, as the case may be, as provided in this Indenture and Additional Amounts, if any, Additional Interest, if any), except payments and distributions made by the Trustee as permitted by the first or second paragraph of Section 13.5, if: (i) a default in the payment of principal, premium, interest, rent or other obligations due on any Senior Indebtedness of the Company has occurred and is continuing (or, in the case of Senior Indebtedness of the Company for which there is a period of grace, in the event of such a default that continues beyond the period of grace, if any, specified in the instrument or lease evidencing such Senior Indebtedness of the Company), unless and until such default shall have been cured or waived or shall have ceased to exist; or (ii) a default (other than a payment default but including any default in the payment of principal, premium, interest, rent or other obligations on Designated Senior Indebtedness that would be a payment default but for the period of grace specified in such instrument or lease) on Designated Senior Indebtedness occurs and is continuing that permits holders of such Designated Senior Indebtedness to accelerate its maturity and the Trustee receives a notice of the default (a "Payment Blockage Notice") from a Representative of Designated Senior Indebtedness or a holder of Designated Senior Indebtedness or the Company. If the Trustee receives any Payment Blockage Notice pursuant to clause (ii) above, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until at least 365 days shall have elapsed since the initial effectiveness of the immediately prior Payment Blockage Notice. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee (unless such default was waived, cured or otherwise ceased to exist and thereafter subsequently reoccurred) shall be, or be made, the basis for a subsequent Payment Blockage Notice. 99 109 The Company may and shall resume payments on and distributions in respect of the Securities upon: (1) in the case of a payment default, the date upon which the default is cured or waived or ceases to exist, or (2) in the case of a default referred to in clause (ii) above, the earlier of the date on which such default is cured or waived or ceases to exist or 179 days after the date on which the applicable Payment Blockage Notice is received if the maturity of such Designated Senior Indebtedness has not been accelerated, unless this Article Thirteen otherwise prohibits the payment or distribution at the time of such payment or distribution (including, without limitation, in the case of default referred to in clause (ii) above, as a result of a payment default with respect to the applicable Senior Indebtedness as a consequence of the acceleration of the maturity thereof or otherwise). Upon any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary, or in bankruptcy, moratorium of payments, insolvency, receivership or other proceedings, all amounts due or to become due upon all Senior Indebtedness of the Company shall first be paid in full in cash or other payment satisfactory to the holders of such Senior Indebtedness of the Company, or payment thereof in accordance with its terms provided for in cash or other payment satisfactory to the holders of such Senior Indebtedness of the Company before any payment is made on account of the principal of, premium, if any, or interest (including Additional Amounts, if any, or Additional Interest, if any) on the Securities by the Company (except payments by the Company made pursuant to Article Four from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings for such dissolution, winding-up, liquidation or reorganization); and upon any such dissolution or winding-up or liquidation or reorganization of the Company or bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders or the Trustee would be entitled, except for the provision of this Article Thirteen, shall (except as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, moratorium of payments, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders or by the Trustee under this Indenture if received by them or it, directly to the holders of Senior Indebtedness of the Company (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness of the Company held by such holders, or as otherwise required by law or a court order) or their Representative or Representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness of the Company may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness of the Company in full, in cash or other payment satisfactory to the holders of such Senior Indebtedness of the Company, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness of the Company, before any payment or distribution is made to the Holders or to the Trustee. 100 110 For purposes of this Article Thirteen, the words, "cash, property or securities" shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article Thirteen with respect to the Securities to the payment of all Senior Indebtedness of the Company which may at the time be outstanding; provided that (i) the Senior Indebtedness of the Company is assumed by the new corporation, if any, resulting from any reorganization or readjustment, and (ii) the rights of the holders of Senior Indebtedness of the Company (other than leases which are not assumed by the Company or the new corporation, as the case may be) are not, without the consent of such holders, altered by such reorganization or readjustment. The merger of the Company into another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article Seven shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 13.2 if such other corporation shall, as a part of such merger, conveyance or transfer, comply with the conditions stated in Article Seven. In the event of the acceleration of the Securities because of an Event of Default, no payment or distribution shall be made to the Trustee or any Holder of Securities in respect of the principal of, premium, if any, or interest on the Securities by the Company (including, but not limited to, the Redemption Price with respect to the Securities called for redemption in accordance with Article Eleven or the Repurchase Price with respect to Securities submitted for repurchase in accordance with Article Fourteen, as the case may be, as provided in this Indenture and Additional Amounts, if any, and Additional Interest, if any), except payments and distributions made by the Trustee as permitted by the first or second paragraph of Section 13.5, until all Senior Indebtedness of the Company has been paid in full in cash or other payment satisfactory to the holders of Senior Indebtedness of the Company or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of the Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Indebtedness of the Company of the acceleration. In the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee or the Holders of the Securities before all Senior Indebtedness of the Company is paid in full in cash or other payment satisfactory to the holders of such Senior Indebtedness of the Company, or provision is made for such payment thereof in accordance with its terms in cash or other payment satisfactory to the holders of such Senior Indebtedness of the Company, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Indebtedness of the Company or their Representative or Representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness of the Company may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness of the Company remaining unpaid to the extent necessary to pay all Senior Indebtedness of the Company in full in cash or other payment satisfactory to the 101 111 holders of such Senior Indebtedness of the Company, after giving effect to any concurrent payment or distribution, or provision therefor, to or for the holders of such Senior Indebtedness of the Company. Nothing in this Article Thirteen shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.7. This Section 13.2 shall be subject to the further provisions of Section 13.5. SECTION 13.3. Subrogation of Securities. Subject to the payment in full in cash of all Senior Indebtedness of the Company, the Holders of the Securities shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness of the Company pursuant to the provisions of this Article Thirteen (equally and ratably with the holders of all indebtedness of the Company which by its express terms is subordinated to other indebtedness of the Company to substantially the same extent as the Securities are subordinated and is entitled to like rights of subrogation) to the rights of the holders of Senior Indebtedness of the Company to receive payments or distributions of cash, property or securities of the Company applicable to the Senior Indebtedness of the Company until the principal, premium, if any, and interest on the Securities shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of the Company of any cash, property or securities to which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article Thirteen, and no payment over pursuant to the provisions of this Article Thirteen, to or for the benefit of the holders of Senior Indebtedness of the Company by Holders of the Securities or the Trustee, shall, as between the Company, its creditors other than holders of Senior Indebtedness of the Company, and the Holders of the Securities, be deemed to be a payment by the Company to or on account of the Senior Indebtedness of the Company. It is understood that the provisions of this Article Thirteen are, and are intended, solely for the purposes of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of the Senior Indebtedness of the Company, on the other hand. Nothing contained in this Article Thirteen or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Indebtedness of the Company, 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 premium, if any) and interest (including Additional Amounts and Additional Interest, if any) 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 the Senior Indebtedness of the Company, nor shall anything 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 Thirteen of the holders of Senior Indebtedness of the Company in respect of cash, property or securities of the Company received upon the exercise of any such remedy. 102 112 Upon any payment or distribution of assets of the Company referred to in this Article Thirteen, the Trustee, subject to the provisions of Section 6.1, 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 such bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such 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 distribution, the holders of the Senior Indebtedness of the Company and other Indebtedness of the Company, the amount thereof or payable thereon and all other facts pertinent thereto or to this Article Thirteen. SECTION 13.4. Authorization to Effect Subordination. Each Holder of a Security by the Holder's acceptance thereof authorizes and directs the Trustee on the Holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article Thirteen and appoints the Trustee to act as the Holder's attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 5.4 hereof at least 30 days before the expiration of the time to file such claim, the holders of any Senior Indebtedness of the Company or their Representatives are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Securities. SECTION 13.5. Notice to Trustee. The Company shall give prompt written notice in the form of an Officers' Certificate to a Responsible Officer of the Trustee and to any Paying Agent of any fact known to the Company which would prohibit the making of any payment of monies deposited by the Company to or by the Trustee or any Paying Agent in respect of the Securities pursuant to the provisions of this Article Thirteen. Notwithstanding the provisions of this Article Thirteen or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment of monies deposited by the Company to or by the Trustee in respect of the Securities pursuant to the provisions of this Article Thirteen, unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the Corporate Trust Office from the Company (in the form of an Officers' Certificate) or a Representative of Senior Indebtedness or of a holder or holders of Senior Indebtedness of the Company or from any trustee thereof; and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 6.1, shall be entitled in all respects to assume that no such facts exist; provided that if on a date not fewer than two Business Days prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the payment of the principal of, or premium, if any, or interest on any Security) the Trustee shall not have received, with respect to such monies, the notice provided for in this Section 13.5, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies deposited by the Company and to apply the same to the purpose for which they were received, 103 113 and shall not be affected by any notice to the contrary which may be received by it on or after such prior date. Notwithstanding anything in this Article Thirteen to the contrary, nothing shall prevent any payment by the Trustee to the Holders of monies deposited with it pursuant to Section 4.1, and any such payment shall not be subject to the provisions of Section 13.1 or 13.2. The Trustee, subject to the provisions of Section 6.1, shall be entitled to rely on the delivery to it of a written notice by a Representative or a Person representing himself to be a holder of Senior Indebtedness of the Company (or a trustee on behalf of such holder) to establish that such notice has been given by a Representative or a holder of Senior Indebtedness of the Company or a trustee on behalf of any such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of the Company to participate in any payment or distribution pursuant to this Article Thirteen, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness of the Company held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article Thirteen, and if such evidence is not furnished the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. SECTION 13.6. Trustee's Relation to Senior Indebtedness of the Company. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article Thirteen in respect of any Senior Indebtedness of the Company at any time held by it, to the same extent as any other holder of Senior Indebtedness of the Company, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. With respect to the holders of Senior Indebtedness of the Company, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article Thirteen, and no implied covenants or obligations with respect to the holders of Senior Indebtedness of the Company 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 Indebtedness of the Company and, subject to the provisions of Section 6.1, the Trustee shall not be liable to any holder of Senior Indebtedness of the Company if it shall pay over or deliver to Holders of Securities, the Company or any other Person money or assets to which any holder of Senior Indebtedness of the Company shall be entitled by virtue of this Article Thirteen or otherwise. SECTION 13.7. No Impairment of Subordination. No right of any present or future holder of any Senior Indebtedness of the Company to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, 104 114 provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with. SECTION 13.8. Article Applicable to Paying Agents. If at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term "Trustee" as used in this Article shall (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided, however, that the first paragraph of Section 13.5 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. SECTION 13.9. Senior Indebtedness of the Company Entitled to Rely. The holders of Senior Indebtedness of the Company (including, without limitation, Designated Senior Indebtedness) shall have the right to rely upon this Article Thirteen, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in writing thereto and such holders may enforce such provisions. SECTION 13.10. Certain Conversions Deemed Payment. For the purposes of this Article Thirteen only, (1) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article Twelve shall not be deemed to constitute a payment or distribution on account of the principal of (or premium, if any) 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 12.2), property or securities (other than junior securities) upon conversion of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes of this Section 13.10, the term "junior securities" means (a) shares of any stock of any class of the Company (including, without limitation, the Common Stock of the Company), or (b) securities of the Company which are subordinated in right of payment to all Senior Indebtedness of the Company which may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article. Nothing contained in this Article Thirteen 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 Indebtedness of the Company and the Holders, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article Twelve. 105 115 ARTICLE FOURTEEN REPURCHASE OF SECURITIES AT THE OPTION OF THE HOLDER UPON A FUNDAMENTAL CHANGE SECTION 14.1. Right to Require Repurchase. In the event that a Fundamental Change (as hereinafter defined) shall occur, then each Holder shall have the right, at the Holder's option, to require the Company to repurchase, and upon the exercise of such right the Company shall repurchase, all of such Holder's Securities, or any portion of the principal amount thereof that is equal to U.S.$1,000 or any integral multiple thereof (provided that no single Security may be repurchased in part unless the portion of the principal amount of such Security to be Outstanding after such repurchase is equal to U.S.$1,000 or integral multiples of U.S.$1,000 in excess thereof), on the date (the "Repurchase Date") that is 45 days after the date of the Company Notice (as defined in Section 14.2) at the following prices (expressed as percentages of the principal amount thereof) (the "Repurchase Price") in the event of a Fundamental Change occurring during the 12-month period beginning October 1 (September 17 in the case of the first period): Year Repurchase Price ---- ---------------- 1997 102% 1998 102 1999 102 2000 102 2001 101 and 100% on October 1, 2002; together in each case, with accrued interest to, but excluding the Repurchase Date; provided that if the Applicable Price with respect to the Fundamental Change is less than the Reference Market Price, the Company shall repurchase such Securities at a price equal to the foregoing Repurchase Price multiplied by the fraction obtained by dividing the Applicable Price by the Reference Market Price; and provided, further, that installments of interest on Securities whose Stated Maturity is on or prior to the Repurchase Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the Regular Record Date according to their terms and the provisions of Section 3.7. Such right to require the repurchase of the Securities shall not continue after a discharge of the Company from its obligations with respect to the Securities in accordance with Article Four, unless a Fundamental Change shall have occurred prior to such discharge. Whenever in this Indenture (including Sections 2.2, 3.1, 5.1(1) and 5.8) there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to the Repurchase Price payable in respect of such Security to the extent that such Repurchase Price is, was or would be so payable at such time, and express mention of the Repurchase Price in any provision of this Indenture shall not be construed as excluding the Repurchase Price in those provisions of this Indenture when such express mention is not made. 106 116 SECTION 14.2. Notices; Method of Exercising Repurchase Right, Etc. (a) Unless the Company shall have theretofore called for redemption of all of the Outstanding Securities, on or before the 30th day after the occurrence of a Fundamental Change, the Company or, at the request and expense of the Company, the Trustee, shall give to all Holders of Securities, in the manner provided in Section 1.6, notice (the "Company Notice") of the occurrence of the Fundamental Change and of the repurchase right set forth herein arising as a result thereof. The Company shall also deliver a copy of such Company Notice to the Trustee. Each notice of a repurchase right shall state: (1) the Repurchase Date, (2) the date by which the repurchase right must be exercised, (3) the Repurchase Price, (4) a description of the procedure which a Holder must follow to exercise a repurchase right, and the place or places where such Securities are to be surrendered for payment of the Repurchase Price and accrued interest, if any, (5) that on the Repurchase Date the Repurchase Price, and accrued interest, if any, will become due and payable upon each such Security designated by the Holder to be repurchased, and that interest thereon shall cease to accrue on and after said date, and (6) the Conversion Price then in effect, the date on which the right to convert the principal amount of the Securities to be repurchased will terminate and the place or places where such Securities may be surrendered for conversion. So long as the Securities are listed on the Luxembourg Stock Exchange and the Luxembourg Stock Exchange shall so require, on or before the 30th day after the occurrence of a Fundamental Change, the Company or, at the request of the Company, the Paying Agent in Luxembourg, will provide notice of such Fundamental Change by publishing such notice in an Authorized Newspaper in Luxembourg, or, if not practicable in Luxembourg, elsewhere in a Western European city. No failure of the Company to give the foregoing notices or defect therein shall limit any Holder's right to exercise a repurchase right or affect the validity of the proceedings for the repurchase of Securities. If any of the foregoing provisions or other provisions of this Article are inconsistent with applicable law, such law shall govern. (b) To exercise a repurchase right, a Holder shall deliver to the Trustee or any Paying Agent on or before the 30th day after the date of the Company Notice (i) written notice of the Holder's exercise of such right, which notice shall set forth the name of the Holder, the principal amount of the Securities to be repurchased (and, if any Security is to be repurchased in 107 117 part, the serial number thereof, the portion of the principal amount thereof to be repurchased and the name of the Person in which the portion thereof to remain Outstanding after such repurchase is to be registered) and a statement that an election to exercise the repurchase right is being made thereby, and (ii) the Securities with respect to which the repurchase right is being exercised. Such written notice shall be irrevocable, except that the right of the Holder to convert the Securities with respect to which the repurchase right is being exercised shall continue until the close of business on the Business Day prior to the Repurchase Date. (c) In the event a repurchase right shall be exercised in accordance with the terms hereof, the Company shall pay or cause to be paid to the Trustee or the Paying Agent the Repurchase Price in cash, as provided above, for payment to the Holder on the Repurchase Date together with accrued and unpaid interest to, but excluding, the Repurchase Date payable with respect to the Securities as to which their purchase right has been exercised; provided, however, that installments of interest that mature on or prior to the Repurchase Date shall be payable in cash, in the case of Securities, to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Date. (d) If any Security (or portion thereof) surrendered for repurchase shall not be so paid on the Repurchase Date, the principal amount of such Security (or portion thereof, as the case may be) shall, until paid, bear interest to the extent permitted by applicable law from the Repurchase Date at the rate of 5% per annum, and each Security shall remain convertible into Common Stock until the principal of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for. (e) Any Security which is to be repurchased only in part shall be surrendered to the Trustee (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 his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, containing identical terms and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Security so surrendered. (f) All securities delivered for repurchase shall be delivered to the Trustee, the Paying Agent or any other agents (as shall be set forth in the Company Notice) to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 3.9. SECTION 14.3. Merger, Consolidation, Etc. In the case of any merger, consolidation, sale or transfer of all or substantially all of the assets of the Company to which Section 12.11 applies, in which the Common Stock of the Company is changed or exchanged as a result into the right to receive shares of stock and other securities or property or assets (including cash) which includes Common Stock of the Company or common stock of another Person that are, or upon issuance will be, traded on a United States national securities exchange or approved for trading on an established automated over-the-counter trading market in the United States and such shares constitute at the time such 108 118 change or exchange becomes effective in excess of 50% of the aggregate fair market value of such shares of stock and other securities, property and assets (including cash) (as determined by the Company, which determination shall be conclusive and binding), then the Company and the Person resulting from such merger or consolidation or which acquires the properties or assets (including cash) of the Company, as the case may be, shall execute and deliver to the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) modifying the provisions of this Indenture relating to the right of Holders to cause the Company to repurchase the Securities following a Fundamental Change, including, without limitation, the applicable provisions of this Article Fourteen and the definitions of the Common Stock and Fundamental Change, as appropriate, and such other related definitions set forth herein, as determined in good faith by the Company (which determination shall be conclusive and binding), to make such provisions apply in the event of a subsequent Fundamental Change to the common stock and the issuer thereof if different from the Company and the Common Stock of the Company (in lieu of the Company and Common Stock of the Company).
