FORM OF REVERSE OF GLOBAL SECURITIES AND DEFINITIVE SECURITIES. This Security is one of a duly authorized issue of Securities of the Company designated as its 7% Convertible Subordinated Notes due 2004 (herein called the "Securities"), limited in aggregate principal amount to $57,500,000 (including Securities issuable pursuant to the Initial Purchasers' over-allotment option, as provided for in the Purchase Agreement dated November 21, 1997 between the Company and the Initial Purchasers), issued and to be issued under an Indenture, dated as of November 15, 1997 (herein called the "Indenture"), between the Company and State Street Bank and Trust Company of California, N.A., as Trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the holders of Senior Indebtedness and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Subject to and upon compliance with the provisions of the Indenture, the Holder of this Security is entitled, at his option, at any time following the date of original issuance of Securities pursuant to the Indenture and on or before the close of business on December 1, 2004, or in case this Security or a portion hereof is called for redemption, then in respect of this Security or such portion hereof until and including, but (unless the Company defaults in making the payment due upon redemption) not after, the close of business on the Business Day preceding the Redemption Date, to convert this Security (or any portion of the principal amount hereof which is $1,000 or an integral multiple thereof), at the principal amount hereof, or of such portion, into fully paid and non-assessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock at a conversion price equal to $19.00 principal amount for each share of Common Stock (or at the current adjusted conversion price if an adjustment has been made as provided in the Indenture) by surrender of this Security, duly endorsed or assigned to the Company or in blank, to the Company at its office or agency maintained for that purpose pursuant to Section 1002 of the Indenture, accompanied by written notice to the Company in the form provided in this Security (or such other notice as is acceptable to the Company) that the Holder hereof elects to convert this Security, or if less than the entire principal amount hereof is to be converted, the portion hereof to be converted, and, in case such surrender shall be made during the period from the opening of business on any Regular Record Date next preceding any Interest Payment Date to the close of business on the Business Day immediately preceding such Interest Payment Date (unless this Security or the portion thereof being converted has been called for redemption during the period from the opening of business day on any Regular Record Date next preceding any Interest Payment Date to close of business on the Second Business Day next succeeding the following Interest Payment Date), also accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of this Security then being converted. If such Security or portion thereof being converted shall have been called for redemption during the period from the close of business on the Regular Record Date to the close of business on the second Business Day next succeeding the following Interest Payment Date, then such Security or portion thereof shall be accompanied by payment in funds acceptable to the Company of an amount equal to the difference between (i) the interest on the principal amount of such Security or portion thereof payable on such Interest Payment Date and (ii) the amount of accrued interest on the principal 18 26 amount of such Security or portion thereof to but not including the date of conversion. Subject to the aforesaid requirement for payment and, in the case of a conversion after the Regular Record Date next preceding any Interest Payment Date and on or before such Interest Payment Date, to the right of the Holder of this Security (or any Predecessor Security) of record at such Regular Record Date to receive an instalment of interest (with certain exceptions provided in the Indenture), no payment or adjustment is to be made upon conversion on account of any interest accrued hereon or on account of any dividends on the Common Stock issued upon conversion. No fractional shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional 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 or the sale or transfer of all or substantially all of the assets of the Company, the Indenture shall be amended, without the consent of any Holders of Securities, so that this Security, if then outstanding, will be convertible thereafter only into the kind and amount of securities, cash and other property receivable upon the consolidation, merger, sale or transfer by a holder of the number of shares of Common Stock into which this Security might have been converted immediately prior to such consolidation, merger, sale or transfer (assuming such holder of Common Stock 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). The Securities are subject to redemption upon not less than 30 and not more than 60 days' notice by mail, at any time on or after December 5, 2000, as a whole or in part, at the election of the Company, at the Redemption Prices set forth below (expressed as percentages of the principal amount), plus accrued interest to the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date). If redeemed during the 12-month period beginning December 1, 2000 (beginning December 5, 2000 and ending on November 30, 2001, in the case of the first such period) the redemption price shall be: YEAR REDEMPTION PRICE 2000 103.00% 2001 102.25 2002 101.50 2003 100.75 2004 100.00% in each case together with accrued and unpaid interest and Liquidated Damages, if any, to, but excluding, the Redemption Date. In certain circumstances involving the occurrence of a Repurchase Event (as defined in the Indenture), the Holder hereof shall have the right to require the Company to repurchase this Security at 100% of the principal amount hereof, together with accrued and unpaid interest and Liquidated Damages, if any, to, but excluding, the Repurchase Date, but interest installments whose Stated Maturity is on or prior to such Repurchase Date will be payable to the Holders of 19 27 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. In the event of redemption or conversion of this Security in part only, a new Security or Securities for the unredeemed or unconverted portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. The indebtedness evidenced by this Security is, in all respects, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness, and this Security is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided, and (c) appoints the Trustee his attorney-in-fact for any and all such purposes. If an Event of Default shall occur and be continuing, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding, and, under certain limited circumstances, by the Company and the Trustee without the consent of the Holders. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed or to convert this Security as provided in the Indenture. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 20 28 The Securities are issuable only in fully registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities of a different authorized denomination, as requested by the Holder surrendering the same. No service charge shall be made for any such registration of transfer or exchange except as provided in the Indenture, and the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, except as provided in this Security, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

STATE STREET BANK AND TRUST COMPANY OF CALIFORNIA, N.A. as Trustee By ---------------------- Authorized Signatory 26 34 ARTICLE THREE THE SECURITIES SECTION 301. TITLE AND TERMS. The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is limited to $57,500,000 (including $7,500,000 aggregate principal amount of Securities that may be sold to the Initial Purchasers by the Company upon exercise of the over-allotment option granted pursuant to the Purchase Agreement), except for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities pursuant to Section 304, 305, 306, 906, 1108, 1302 or 1405. The Securities shall be known and designated as the "7% Convertible Subordinated Notes due 2004" of the Company. Their Stated Maturity shall be December 1, 2004 and they shall bear interest at the rate of 7% per annum, from the date of original issuance of Securities pursuant to this Indenture or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, payable semi-annually on June 1 and December 1 commencing June 1, 1998, until the principal thereof is paid or made available for payment. The principal of and premium, if any, and interest on the Securities shall be payable (i) in respect of Securities held of record by the Depositary or its nominee in same day funds on or prior to the respective payment dates and (ii) in respect of Securities held of record by Holders other than the Depositary or its nominee in same day funds at the office or agency of the Company maintained for such purpose pursuant to Section 1002; provided, however, that at the option of the Company payment of interest to Holders of record other than the Depositary may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. The Securities shall be subject to the transfer restrictions set forth in Section 305. The Securities shall be redeemable as provided in Article Eleven. The Securities shall be subordinated in right of payment to Senior Indebtedness as provided in Article Twelve. The Securities shall be convertible as provided in Article Thirteen.

The Securities shall be issuable only in fully registered form without coupons and only in denominations of $1,000 and any integral multiple thereof. SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING. The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its President or one of its Vice Presidents, under its corporate seal or a facsimile thereof reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of 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 for authentication, together with a Company Order for the authentication and delivery of such Securities; and the Trustee in accordance with such Company Order shall either at one time or from time to time pursuant to such instructions as may be described therein authenticate and deliver such Securities as in this Indenture provided and not otherwise. Such Company Order shall specify the amount of Securities to be authenticated and the date on which the original issue of Securities is to be authenticated, and shall certify that all conditions precedent to the issuance of such Securities contained in this Indenture have been complied with. The aggregate principal amount of Securities Outstanding at any time may not exceed the amount set forth above except as provided in Section 306. Each Security shall be dated the date of its authentication. 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 duly executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of the Indenture. The Trustee may appoint an Authenticating Agent pursuant to the terms of Section 614. SECTION 304. TEMPORARY SECURITIES. Pending the preparation of Definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the Definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the 28 36 officers executing such Securities may determine, as evidenced by their execution of such Securities. Every such temporary Security shall be executed by the Company and shall be authenticated and delivered by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the Definitive Security or Securities in lieu of which it is issued. Not including Global Securities, if temporary Securities are issued, the Company will cause Definitive Securities to be prepared without unreasonable delay. After the preparation of Definitive Securities, the temporary Securities shall be exchangeable for Definitive Securities upon surrender of the temporary Securities at any office or agency of the Company designated pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more Definitive Securities of a like principal amount of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as Definitive Securities. SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE. (a) 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 designated pursuant to Section 1002 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 of Securities as herein provided. At all reasonable times the Security Register shall be open for inspection by the Company. The Company initially appoints The Depository Trust Company ("DTC") to act as depositary (the "Depositary") with respect to the Global Security(ies). The Company initially appoints the Trustee to act as Securities Custodian with respect to the Global Security(ies). (b) So long as the Securities are eligible for book-entry settlement with the Depositary, or unless otherwise required by law, all Securities that are so eligible may be represented by one or more Global Securities registered in the name of the Depositary or the nominee of the Depositary, except as otherwise specified below. The transfer and exchange of beneficial interests in any such Global Security shall be effected through the Depositary in accordance with this Indenture and the procedures of the Depositary therefor. Transfers of interests in the Securities between the 144A Global Security and the Regulation S Global Security will be made in accordance with the standing instructions and procedures of the Depositary and its participants. The Trustee shall make appropriate endorsements to reflect increases or decreases in the principal amounts of such Global Securities as set forth on the face of the Security ("Principal Amount") to reflect any such transfers. 29 37 Except as provided below, beneficial owners of a Global Security shall not be entitled to have certificates registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and will not be considered Holders of such Global Securities. (c) So long as the Securities are eligible for book-entry settlement, or unless otherwise required by law, upon any transfer of a Definitive Security to a QIB in accordance with Rule 144A or to a Non-U.S. Person in accordance with Regulation S, and upon receipt of the Definitive Security or Securities being so transferred, together with a certification, substantially in the form on the reverse of the Security, from the transferor that the transfer is being made in compliance with Rule 144A or Regulation S, as the case may be (or other evidence satisfactory to the Trustee), the Trustee shall make an endorsement on the 144A Global Security or the Regulation S Global Security, as the case may be, to reflect an increase in the aggregate Principal Amount of the Securities in accordance with the standing instructions and procedures of the Depositary, the aggregate Principal Amount of Securities represented by such Global Security to be increased accordingly; provided that no Definitive Security, or portion thereof, in respect of which the Company or an Affiliate of the Company held any beneficial interest shall be included in such Global Security until such Definitive Security is freely tradable in accordance with Rule 144(k); provided further that the Trustee shall issue Definitive Securities upon any transfer of a beneficial interest in the Global Security to the Company or any Affiliate of the Company. Upon any sale or transfer of a Security to an Institutional Accredited Investor (other than pursuant to a registration statement that has been declared effective under the Securities Act and remains effective at the time of such sale or transfer), such Institutional Accredited Investor shall, prior to such sale or transfer, furnish to the Company and/or the Trustee a signed letter containing representations and agreements relating to restrictions on transfer substantially in the form set forth in Exhibit A to this Indenture. Any 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 Securities Custodian, the Depositary or by the National Association of Securities Dealers, Inc. in order for the Securities to be tradeable on The Portal Market or as may be required for the Securities to be tradeable 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 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 imitations or restrictions to which any particular Securities are subject. (d) The Depositary shall be a clearing agency registered under the Exchange Act. Initially, the 144A Global Security and the Regulation S Global Security shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Securities Custodian for Cede & Co. If a Definitive Security is issued in exchange for any portion of a Global Security after the close of business at the office or agency where such exchange occurs on any Record Date 30 38 and before the opening of business at such office or agency on the next succeeding Interest Payment Date, interest will not be payable on such Interest Payment Date in respect to such Security, but will be payable on such Interest Payment Date, subject to the provisions of Section 307, only to the Person to whom interest in respect of such portion of such Global Security is payable in accordance with the provisions of this Indenture. Definitive Securities issued in exchange for all or a part of a Global Security pursuant to this Section 305 shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Definitive Securities to the Persons in whose names such Definitive Securities are so registered. At such times as all interests in a Global Security have been redeemed, repurchased, converted, canceled, exchanged for Definitive Securities or transferred to a transferee who receives Definitive Securities thereof, 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 Securities Custodian. At any time prior to such cancellation, if any interest in a Global Security is exchanged for Definitive Securities or redeemed, converted, repurchased or canceled, exchanged for Definitive Securities or transferred to a transferee who receives Definitive Securities therefor or any Definitive Security is exchanged or transferred for part of a Global Security, the principal amount of such Global Security shall, in accordance with the standing procedures and instructions existing between the Depositary and the Securities Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Security, by the Trustee or the Securities Custodian, at the direction of the Trustee, to reflect such reduction or increase. (e) Notwithstanding any other provisions of this Indenture (other than the provisions set forth in subsection (c) of this Section 305), a Global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. (f) The following relates to the authentication of Definitive Securities in absence of the Depositary. If at any time: (i) the Depositary for the Global Securities notifies the Company that the Depositary is unwilling or unable to continue as Depositary for the Global Securities and a successor Depositary for the Global Securities is not appointed by the Company within 90 days after delivery of such notice; or (ii) the Company, at its sole discretion, notifies the Trustee in writing that it elects to cause the issuance of Definitive Securities under this Indenture, then the Company will execute, and the Trustee, upon receipt of a Company Order in accordance with Section 303 requesting the authentication and delivery of Definitive Securities, will authenticate and deliver Definitive Securities in an aggregate principal amount equal to the principal amount of the Global Securities, in exchange for such Global Securities. (g) Until two years after the date of original issuance of the Securities, each Security certificate evidencing the Global Securities and the Definitive Securities (and all Securities issued in exchange therefor or substitution thereof) shall bear a legend in substantially the 31 39 following form, unless otherwise agreed by the Company in writing, with notice to the Trustee (unless such Security shall be sold pursuant to a registration statement that is effective at the time of such sale): THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS, AND, ACCORDINGLY, NEITHER THIS SECURITY, THE SHARES OF COMMON STOCK ISSUABLE UPON CONVERSION OF THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN OR THEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM OR NOT SUBJECT TO, REGISTRATION. THE HOLDER OF THIS SECURITY, BY ITS ACQUISITION HEREOF, AGREES THAT IT WILL NOT, PRIOR TO THE DATE WHICH IS TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF, RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH SECURITY EXCEPT (A) TO ATRIX LABORATORIES, INC. OR A SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE UNITED STATES TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO STATE STREET BANK AND TRUST COMPANY OF CALIFORNIA, N.A., AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE), A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THE SECURITY EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH TRUSTEE OR SUCCESSOR TRUSTEE, AS APPLICABLE), (D) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, (E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (F) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); AND AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE SECURITY EVIDENCED HEREBY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THE SECURITY EVIDENCED HEREBY WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF SUCH SECURITY, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO STATE STREET BANK AND TRUST COMPANY OF CALIFORNIA, N.A., AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR OR A PURCHASER WHO IS NOT A U.S. PERSON, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO STATE STREET BANK AND TRUST COMPANY OF CALIFORNIA, N.A., AS TRUSTEE OR A SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL 32 40 OPINIONS OR OTHER INFORMATION AS IT 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. THIS LEGEND WILL BE REMOVED UPON ANY TRANSFER OF THE SECURITY EVIDENCED HEREBY AFTER THE EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE SECURITY EVIDENCED HEREBY. AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT. (h) All Definitive Securities and Global Securities issued upon any registration of transfer or exchange of Definitive Securities or Global Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Definitive Securities or Global Securities surrendered upon such registration of transfer or exchange. (i) To the extent requested by the Trustee, all Securities the transfer, exchange and/or registration of which is effectuated pursuant to this Section 305 shall be accompanied by an Officers' Certificate of the Company, certifying that such transfer, exchange and/or registration is authorized by the Company and permitted hereunder. (j) Any Security or Common Stock issued upon the conversion or exchange of a Security that, on or prior to two years after the original issuance of the Securities, is purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction which results in such Securities or Common Stock issuable upon conversion thereof, as the case may be, no longer being "restricted securities" (as defined under Rule 144). (k) To permit registrations of transfer and exchanges, the Company shall execute and the Trustee shall authenticate Definitive Securities and Global Securities at the Security Registrar's request. (l) No service charge to a Holder shall be made for any registration of transfer or exchange of Securities except as provided in Section 306. 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 304, 906, 1108, 1302 or 1405 not involving any transfer. (m) The Company or the Security Registrar shall not be required (i) to issue, register the transfer of or exchange any Security during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities selected for redemption under Section 1104 and ending at the close of business on the day of such mailing, (ii) to register the transfer of or exchange any Definitive Security or beneficial interest in any Global Security so selected for redemption in whole or in part, except the unredeemed portion of any Definitive Security being redeemed in part or (iii) to register the transfer of or exchange of any Definitive 33 41 Security or beneficial interest in any Global Security surrendered for conversion pursuant to Article Thirteen or repurchase (and not withdrawn) pursuant to Article Fourteen. SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. The Trustee may charge the Company for the Trustee's expenses in replacing such Security. 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 may, instead of issuing a new Security, pay such Security. Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and 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 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. SECTION 307. 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. Payment of interest will be made (i) in respect of Securities held by the Depositary or its nominee, in same day funds on or prior to the respective Interest Payment Dates and (ii) in respect of Securities held of record by Holders other than the Depositary or its nominee, in same day funds at the office or agency of the Trustee in New York, New York or at 34 42 such other office or agency of the Company as it shall maintain for that purpose pursuant to Section 1002, provided, however, that, at the option of the Company, interest on any Security held of record by Holders other than the Depositary or its nominee may be paid by mailing checks to the addresses of the Holders thereof as such addresses appear in the Securities Register. 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 in this Clause provided. Thereupon the Trustee shall fix a 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 at his address as it appears in the Security Register, not less than 10 days 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. In the case of any Security which is converted after any Regular Record Date and on or prior to the Business Day immediately preceding such Interest Payment Date (other than any 35 43 Security whose Maturity is prior to such Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) 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 such Regular Record Date; provided, however, that Securities so surrendered for conversion shall (except in the case of Securities or portions thereof called for redemption which is addressed in Section 1302 below) be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount being surrendered for conversion. Except as otherwise expressly provided above in this subsection (2) and in Section 1302, in the case of any Security which is converted, interest whose Stated Maturity is after the date of conversion of such Security shall not be payable. SECTION 308. PERSONS DEEMED OWNERS. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and premium, if any, and (subject to Section 307) 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. SECTION 309. CANCELLATION. All Securities surrendered for payment, redemption, registration of transfer, exchange or conversion shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be destroyed by the Trustee, unless otherwise directed by a Company Order. SECTION 310. COMPUTATION OF INTEREST. Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months. 36 44 ARTICLE FOUR SATISFACTION AND DISCHARGE SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE. This Indenture shall upon Company Request cease to be of further effect (except as expressly provided for in this Article Four), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (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 306 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or (B) all such Securities not theretofore delivered to the Trustee for cancellation (i) have become due and payable, or (ii) will 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, or (iv) are delivered to the Trustee for Conversion in accordance with Article Thirteen, and the Company, in the case of (i), (ii), (iii) or (iv) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose an amount in cash sufficient (without consideration of any investment of such cash) to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation for principal and premium, if any, and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided that the Trustee shall have been irrevocably instructed to apply such amount to said payments with respect to the Securities; (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 following rights or obligations under the Securities and this Indenture shall survive until otherwise terminated or discharged hereunder: (a) Article Thirteen, Article Fourteen and the Company's obligations under Sections 304, 305, 306, 1002 and 1003, in each case with respect to any Securities described in subclause (B) of Clause (1) of this Section, (b) this Article Four, (c) the rights, powers, trusts, duties and immunities of the Trustee 37 45 hereunder, including the obligations of the Company to the Trustee under Section 607, and the obligations of the Trustee to any Authenticating Agent under Section 614 and (d) if money shall have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of this Section, the rights of Holders of any Securities described in subclause (B) of Clause (1) of this Section to receive, solely from the trust fund described in such subclause (B), payments in respect of the principal of, and premium (if any) and interest on, such Securities when such payment are due. SECTION 402. APPLICATION OF TRUST MONEY. Subject to the provisions of the last paragraph of Section 1003 and Section 506, all money deposited with the Trustee pursuant to Section 401 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 and premium, if any, and interest for whose payment such money has been deposited with the Trustee. All moneys deposited with the Trustee pursuant to Section 401 (and held by it or any Paying Agent) for the payment of Securities subsequently converted shall be returned to the Company upon Company Request. SECTION 403. REINSTATEMENT. If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article Four by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article Four until such time as the Trustee or Paying Agent is permitted to apply all money held in trust with respect to the Securities; provided, however, that if the Company makes any payment of principal of, or any premium or interest on, any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of the Securities to receive such payment from the money so held in trust.

or (6) default under one or more bonds, debentures, notes or other evidences of indebtedness for money borrowed by the Company or any Subsidiary or under one or more mortgages, indentures or instruments under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company or any Subsidiary, whether such indebtedness now exists or shall hereafter be created, which default individually or in the aggregate shall constitute a failure to pay the principal of indebtedness in excess of $5,000,000 when due and payable after the expiration of any applicable grace period with respect thereto or shall have resulted in indebtedness in excess of $5,000,000 becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such indebtedness having been discharged, or such acceleration having been rescinded or annulled, within a period of 30 days after there shall have 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 principal amount of the Outstanding Securities a written notice specifying such default and requiring the Company to cause such indebtedness to be discharged or cause such acceleration to be rescinded or annulled and stating that such notice is a "Notice of Default" hereunder; or (7) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company or any Subsidiary in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company or any Subsidiary as bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or any Subsidiary under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any Subsidiary or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 90 consecutive days; or 39 47 (8) the commencement by the Company or any Subsidiary of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company or any Subsidiary in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State 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 any Subsidiary or of any substantial part of its property, or the making by it of a general 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 or any Subsidiary in furtherance of any such action. Upon receipt by the Trustee of any Notice of Default pursuant to this Section 501, a record date shall automatically and without any other action by any Person be set for the purpose of determining the Holders of Outstanding Securities entitled to join in such Notice of Default, which record date shall be the close of business on the day the Trustee receives such Notice of Default. The Holders of Outstanding Securities on such record date (or their duly appointed agents), and only such Persons, shall be entitled to join in such Notice of Default, whether or not such Holders remain Holders after such record date: provided, that unless such Notice of Default shall have become effective by virtue of the Holders of the requisite principal amount of Outstanding Securities on such record date (or their duly appointed agents) having joined therein on or prior to the 90th day after such record date, such Notice of Default shall automatically and without any action by any Person be canceled and of no further force or effect. SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If an Event of Default (other than as specified in subparagraph (7) or (8) of Section 501) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in 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 Holders), and upon any such declaration such principal plus any interest accrued on the Securities to the date of declaration shall become immediately due and payable. If an Event of Default specified in subparagraph (7) or (8) of Section 501 occurs and is continuing with respect to the Company, then the principal of, premium, if any, and accrued and unpaid interest, if any, on all of the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of Securities. At any time after such a 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 40 48 Article provided, the Holders of a majority in principal amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such 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 Liquidated Damages, if any) 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 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 the rate borne by the Securities, and (D) all sums paid or advanced by the Trustee and each predecessor Trustee, their respective agents and counsel hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee and each predecessor Trustee, their respective agents and counsel; and (2) all Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Securities that has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. No such rescission and waiver shall affect any subsequent default or impair any right consequent thereon. Upon receipt by the Trustee of any declaration of acceleration, or any rescission and annulment of any such declaration, pursuant to this Section 502, a record date shall automatically and without any other action by any Person be set for the purpose of determining the Holders of Outstanding Securities entitled to join in such declaration, or rescission and annulment, as the case may be, which record date shall be the close of business on the day the Trustee receives such declaration, or rescission and annulment, as the case may be. The Holders of Outstanding Securities on such record date (or their duly appointed agents), and only such Persons, shall be entitled to join in such declaration, or rescission and annulment, as the case may be, whether or not such Holders remain Holders after such record date; provided, that unless such declaration, or rescission and annulment, as the case may be, shall have become effective by virtue of Holders of the requisite principal amount of Outstanding Securities on such record date (or their duly appointed agents) having joined therein on or prior to the 90th day after such record date, such declaration, or rescission and annulment, as the case may be, shall automatically and without any action by any Person be canceled and of no further force or effect. SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE. The Company covenants that if 41 49 (1) default is made in the payment of any interest (including Liquidated Damages, if any) on any Security when such interest 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 it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal of, and premium, if any, and interest, and, to the extent that payment of such interest (including Liquidated Damages, if any) shall be legally enforceable, interest, on any overdue principal and premium, if any, and on any overdue interest (including Liquidated Damages, if any), at the rate borne by the Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee and each predecessor Trustee, their respective agents and counsel, and any other amounts due the Trustee or any predecessor Trustee under Section 607. 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 and may prosecute any 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 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 504. TRUSTEE MAY FILE PROOFS OF CLAIM. In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have the claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims 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 to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it and each predecessor Trustee for the reasonable compensation, expenses, disbursements and advances of the Trustee and each predecessor Trustee and their respective agents and counsel, and any other amounts due the Trustee under Section 607. 42 50 No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and may be a member of the Creditors' Committee. SECTION 505. 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 and each predecessor Trustee and their respective agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. SECTION 506. APPLICATION OF MONEY COLLECTED. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or premium, if any, or interest (including Liquidated Damages, if any), 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 payment of all amounts due the Trustee under Section 607; SECOND: Subject to Article Twelve, to the holders of Senior Indebtedness; THIRD: To the payment of the amounts then due and unpaid for principal of and premium, if any, and interest and Liquidated Damages, if any 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 and premium, if any, and interest and Liquidated Damages, if any, respectively; and FOURTH: The balance, if any, to the Company or any other Person or Persons determined to be entitled thereto upon provision of an Officer's Certificate or other evidence reasonably satisfactory to the Trustee by the Company or such other person verifying such entitlement. 43 51 SECTION 507. 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; (2) the Holders of not less than 25% in 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 satisfactory to it 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 principal amount of the Outstanding Securities; it being understood and intended that no one or more 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 Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders. SECTION 508. 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 and premium, if any, and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date or, in the case of a repurchase pursuant to Article Fourteen, on the Repurchase Date) and to convert such Security in accordance with Article Thirteen 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 509. RESTORATION OF RIGHTS AND REMEDIES. If the Trustee or any Holder 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 shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 44 52 SECTION 510. RIGHTS AND REMEDIES CUMULATIVE. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders 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 511. 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 an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. SECTION 512. CONTROL BY HOLDERS. The Holders of a majority in 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; and (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and (3) subject to the provisions of Section 601, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall determine that the action so directed would involve the Trustee in personal liability or would be unduly prejudicial to Holders not joining in such direction. Upon receipt by the Trustee of any such direction, a record date shall automatically and without any other action by any Person be set for the purpose of determining the Holders of Outstanding Securities entitled to join in such direction, which record date shall be the close of business on the day the Trustee receives such direction. The Holders of Outstanding Securities on such record date (or their duly appointed agents), and only such Persons, shall be entitled to join in such direction, whether or not such Holders remain Holders after such record date; provided, that unless such direction shall have become effective by virtue of Holders of the requisite principal amount of Outstanding Securities on such record date (or their duly appointed agents) having joined therein on or prior to the 90th day after such record date, such direction shall automatically and without any action by any Person be canceled and of no further force or effect. 45 53 SECTION 513. WAIVER OF PAST DEFAULTS. The Holders of not less than a majority in principal amount of the Outstanding Securities 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 or premium, if any, or interest on any Security, or (2) in respect of a covenant or provision hereof which under Article Nine 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 514. UNDERTAKING FOR COSTS. 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, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided, that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company, in any suit instituted by the Trustee, a suit by a Holder pursuant to Section 508, or a suit by a Holder or Holders of more than 10% in principal amount of the outstanding Securities. ARTICLE SIX THE TRUSTEE SECTION 601. CERTAIN DUTIES AND RESPONSIBILITIES. The duties and responsibilities of the Trustee shall be as provided by this Indenture and the Trust Indenture Act for securities issued pursuant to indentures qualified thereunder. Except as otherwise provided herein, notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability or risk 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 satisfactory to it against such risk or liability is not reasonably assured to it. 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. The Trustee shall not be liable (x) for any error of judgment made in 46 54 good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts or (y) 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 not less than a majority in aggregate principal amount of the Securities at the time Outstanding relating to the time, method and place of conducting any proceeding or any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture. Prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred: (i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and in the Trust Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and in the Trust Indenture Act, and no implied covenants or obligations shall be read in to this Indenture against the Trustee; and (ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions therein, upon any statements, certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture and believed by the Trustee to be genuine and to have been signed or presented by the proper party or parties; but in the case of any such statements, certificates or opinions which by any provisions 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 on their face to the requirements of this Indenture. If a default or an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise thereof as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. SECTION 602. NOTICE OF DEFAULTS. The Trustee shall give the Holders notice of any default hereunder of which it has actual knowledge as and to the extent provided by the Trust Indenture Act; provided, however, that in the case of any default of the character specified in Section 501(5), no such notice to Holders 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 603. CERTAIN RIGHTS OF TRUSTEE. Subject to the provisions of Section 601: (a) the Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, 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; (b) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution; 47 55 (c) 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 conclusively upon an Officers' Certificate; (d) the Trustee may consult with counsel and the written 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; (e) 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 pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; (f) before the Trustee acts or refrains from acting with respect to any matter contemplated by this Indenture, it may require an Officers' Certificate or an Opinion of Counsel, which shall conform to the provisions of Section 102, and the Trustee shall be protected and shall not be liable for any action it takes or omits to take in good faith and without gross negligence in reliance on such certificate or opinion; (g) the Trustee shall not be required to give any bond or surety in respect of the performance of its power and duties hereunder; (h) 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, other evidence of indebtedness or other paper or document, but the Trustee, in its 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; and (i) 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. SECTION 604. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES. The recitals contained herein and in the Securities, except the Trustee's certificate of authentication, shall be taken as the statements of the Company, and the Trustee and any Authenticating Agent assume no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. The Trustee and any Authenticating Agent shall not be accountable for the use or application by the Company of Securities or the proceeds thereof. 48 56 SECTION 605. MAY HOLD SECURITIES. The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. SECTION 606. MONEY HELD IN TRUST. Money held by the Trustee or any Paying Agent in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee or any Paying Agent shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company. SECTION 607. COMPENSATION AND REIMBURSEMENT. The Company agrees: (1) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (including its services as Security Registrar or Paying Agent, if so appointed by the Company) as may be mutually agreed upon in writing by the Company and the Trustee (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 and each predecessor Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in connection with the performance of its duties under any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel and all other persons not regularly in its employ) except to the extent any such expense, disbursement or advance may be attributable to its negligence or bad faith; and (3) to indemnify the Trustee and each predecessor Trustee (each an "indemnitee") for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder and its duties hereunder (including its services as Security Registrar or Paying Agent, if so appointed by the Company), including enforcement of this Section 607 and including the costs and expenses of defending itself against or investigating any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Company shall defend any claim or threatened claim asserted against an indemnitee for which it may seek indemnity, and the indemnitee shall cooperate in the defense unless, in the reasonable opinion of the indemnitee's counsel, the indemnitee has an interest adverse to the Company or a potential conflict of interest exists between the indemnitee and the Company, in which case the indemnitee may have separate counsel and the Company shall pay 49 57 the reasonable fees and expenses of such counsel; provided that the Company shall only be responsible for the reasonable fees and expenses of one law firm (in addition to local counsel) in any one action or separate substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, such law firm to be designated by the indemnitee. As security for the performance of the obligations of the Company under this Section 607, the Trustee shall have a lien prior to the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities, and the Securities are hereby subordinated to such prior lien. The obligations of the Company under this Section to compensate and indemnify the Trustee and any predecessor Trustee and to pay or reimburse the Trustee and any predecessor Trustee for expenses, disbursements and advances, and any other amounts due the Trustee or any predecessor Trustee under Section 607, shall constitute an additional obligation hereunder and shall survive the satisfaction and discharge of this Indenture. When the Trustee or any predecessor Trustee incurs expenses or renders services in connection with the performance of its obligations hereunder (including its services as Security Registrar or Paying Agent, if so appointed by the Company) after an Event of Default specified in Section 501(7) or (8) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any applicable bankruptcy, insolvency or other similar federal or state law to the extent provided in Section 503(b)(5) of Title 11 of the United States Code, as now or hereafter in effect. SECTION 608. 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 609. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY. There shall at all times be a Trustee hereunder which shall be a Person that (i) is eligible pursuant to the Trust Indenture Act to act as such, (ii) has (or, in the case of a corporation included in a bank holding company system, whose related bank holding company has) a combined capital and surplus of at least $50,000,000 and (iii) has an office where it provides corporate trust services, or at which it is authorized to receive notices hereunder, in the Borough of Manhattan, The City of New York, or a designated agent. If such Person publishes reports of conditions at least annually, pursuant to law or to the requirements of a Federal or state supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person 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. 50 58 SECTION 610. 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 611.

Any successor Authenticating Agent upon acceptance of its appointment under this Section 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 to act as such under the provisions of this Section.

In any case where more than one Security is registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered as if it were represented by one Security. 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 1105. NOTICE OF REDEMPTION. Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to the Trustee and to each Holder of Securities to be redeemed, at his address appearing in the Security Register. All notices of redemption shall state: (a) the Redemption Date, (b) the Redemption Price, (c) if less than all the Outstanding Securities are to be redeemed, the identification (and, in the case of partial redemption of any Securities, the principal amounts) of the particular Securities to be redeemed, 64 72 (d) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and that (unless the Company shall default in payment of the Redemption Price) interest thereon will cease to accrue on and after said date, (e) the conversion price, the date on which the right to convert the Securities to be redeemed will terminate (which right shall extend at least until one business day prior to the Redemption Date) and the place or places where such Securities may be surrendered for conversion, and (f) the place or places where such Securities are to be surrendered for payment of the Redemption Price. 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 request received by the Trustee at least 30 days prior to the Redemption Date, by the Trustee in the name and at the expense of the Company. SECTION 1106. DEPOSIT OF REDEMPTION PRICE. On or prior to 10:00 a.m. (New York City time) on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in same day funds sufficient to pay the Redemption Price of, and accrued and unpaid interest (including Liquidated Damages, if any) on, all the Securities or portions thereof 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 any Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive interest as provided in the last paragraph of Section 307) be paid to the Company upon Company Request or, if then held by the Company, shall be discharged from such trust. SECTION 1107. 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 and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such 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 (including Liquidated Damages, if any) to, but excluding, the Redemption Date; provided, however, that installments of interest whose 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 at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307. 65 73 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and premium, if any, shall, until paid, bear interest from the Redemption Date at the rate borne by the Security. SECTION 1108. 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 maintained for that purpose pursuant to Section 1002 (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 deliver to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. ARTICLE TWELVE SUBORDINATION OF SECURITIES SECTION 1201. SECURITIES SUBORDINATED TO SENIOR INDEBTEDNESS. The Company covenants and agrees, and each Holder of a Security, by his acceptance thereof, likewise covenants and agrees, that, at all times and in all respects, the indebtedness represented by the Securities and the payment of the principal of and premium, if any, and interest on each and all of the Securities are hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness. SECTION 1202. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC. In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding, relative to the Company or to its creditors, as such, or to a substantial part of its assets, or (b) any proceeding for the liquidation, dissolution or other winding up of the Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any general assignment for the benefits of creditors or any other marshaling of assets and liabilities of the Company, then and in any such event the holders of Senior Indebtedness shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Indebtedness; or provision shall be made for such payment in money or money's worth, before the Holders of the Securities are entitled to receive any payment or distribution of any kind or character, whether in cash, property or securities, on account of principal of or premium, if any, or interest on the Securities, and to that end the holders of Senior Indebtedness shall be entitled to receive, for application to the payment thereof, any payment or distribution of any kind or character, whether in cash, property or securities, including any such payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of the Securities, which may be payable or deliverable in respect of the Securities in any such case, proceeding, dissolution, liquidation or other winding up or event. 66 74 In the event that, notwithstanding the foregoing provisions of this Section, the Trustee or the Holder of any Security shall have received any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, including any such payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of the Securities, before all Senior Indebtedness is paid in full or payment thereof provided for, and if such fact shall, at or prior to the time of such payment or distribution, have been made known to the Trustee or such Holder, as the case may be, then and in such event such payment or distribution shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other Person making payment or distribution of assets of the Company for application to the payment of all Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior Indebtedness in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness. For purposes of this Article only, the words "cash, property or securities" shall not be deemed to include securities 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, which are subordinated in right of payment to all Senior Indebtedness which may at the time be outstanding to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article. The consolidation of the Company with, or the merger of the Company into, another Person or the liquidation or dissolution of the Company following the conveyance or transfer of its properties and assets substantially as an entirety to another Person upon the terms and conditions set forth in Article Eight shall not be deemed a dissolution, winding up, liquidation, reorganization, general assignment for the benefit of creditors or marshaling of assets and liabilities of the Company for the purposes of this Section if the Person formed by such consolidation or into which the Company is merged or which acquires by conveyance or transfer such properties and assets substantially as an entirety, as the case may be, shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions set forth in Article Eight. SECTION 1203. PRIOR PAYMENT TO SENIOR INDEBTEDNESS UPON ACCELERATION OF SECURITIES. In the event that any Securities are declared due and payable before their Stated Maturity, then and in such event the holders of Senior Indebtedness outstanding at the time such Securities so become due and payable shall be entitled to receive payment in full of all amounts due on or in respect of such Senior Indebtedness, or provision shall be made for such payment in money or money's worth, before the Holders of the Securities are entitled to receive any payment (including any payment which may be payable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of the Securities) by the Company on account of the principal of or premium, if any, or interest on the Securities or on account of the purchase or other acquisition of Securities. In the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee or the Holder of any Security prohibited by the foregoing provisions of this Section, 67 75 and if such fact shall, at or prior to the time of such payment, have been made known to the Trustee or such Holder, as the case may be, then and in such event such payment shall be paid over the delivered forthwith to the Company. The provisions of this Section shall not apply to any payment with respect to which Section 1202 would be applicable. SECTION 1204. PAYMENT WHEN DESIGNATED SENIOR INDEBTEDNESS IN DEFAULT. No payment shall be made with respect to the principal of, or premium, if any, or interest on any Security (including, but not limited to, the redemption price or the Repurchase Price with respect to the Security to be called for redemption in accordance with Article 11 or submitted for repurchase in accordance with Article 16, as the case may be, as provided in this Agreement), except payments and distributions made by the Trustee as permitted by Section 1210, if: (a) a default in the payment of principal, premium, interest, rent or other obligations due on any Designated Senior Indebtedness occurs and is continuing (or, in the case of Designated Senior Indebtedness 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 Designated Senior Indebtedness), unless and until such default shall have been cured or waived or shall have ceased to exist (a "Payment Default"); or (b) a default, other than a Payment Default, on any Designated Senior Indebtedness occurs and is continuing that then permits holders of such Designated Senior Indebtedness to accelerate its maturity (a "Non Payment Default") and the Trustee receives a notice of default (a "Payment Blockage Notice") from (a) if such Nonpayment Default shall have occurred under any debt facility referred to in the definition of "Designated Senior Indebtedness", the representative of such debt facility, or (b) if such Nonpayment Default shall have occurred with respect to any other issue of Designated Senior Indebtedness, the holders, or a representative of the holders, of at least 20% of such Designated Senior Indebtedness, as the case may be. If the Trustee receives any payment Blockage Notice pursuant to clause (b) 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 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 shall be, or be made, the basis for a subsequent Payment Blockage Notice. The Company may and shall resume payments on and distributions in respect of the Securities upon the earlier of: (i) in the case of a Payment Default respecting Designated Senior Indebtedness, on the date of which that default is cured or waived or ceases to exist and 68 76 (ii) in the case of a Nonpayment Default respecting Designated Senior Indebtedness, the earliest of (a) the date on which that Nonpayment Default is cured or waived or ceases to exist, (b) the date the applicable Payment Blockage Notice is retracted by written notice to the Trustee from the holders or a representative of the holders of the Designated Senior Indebtedness which have given that Payment Blockage Notice and (c) 179 days after the date on which the applicable Payment Blockage Notice is received by the Trustee, unless any Payment Default has occurred and is continuing or an Event of Default of the type referred to in (7) or (8) of Section 501 of this Indenture has occurred with respect to the Company. In the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee or the Holder of any Security prohibited by the foregoing provisions of this Section, and if such fact shall, at or prior to the time of such payment, have been made known to the Trustee or such Holder, as the case may be, then and in such event such payment shall be paid over and delivered forthwith to the Company. The provisions of this Section shall not apply to any payment with respect to which Section 1202 would be applicable. SECTION 1205. PAYMENT PERMITTED IF NO DEFAULT. Nothing contained in this Article or elsewhere in this Indenture or in any of the Securities shall prevent (a) the Company, at any time except during the pendency of any case, proceeding, dissolution, liquidation or other winding up, general assignment for the benefit of creditors or other marshaling of assets and liabilities of the Company referred to in Section 1202 or under the conditions described in Section 1203 or 1204, from making payments at any time of principal of and premium, if any, or interest on the Securities, or (b) the application by the Trustee of any money deposited with it hereunder to the payment of or on account of the principal of and premium, if any, or interest on the Securities or the retention of such payment by the Holders, if, at the time of such application by the Trustee, it did not have knowledge that such payment would have been prohibited by the provisions of this Article. SECTION 1206. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS. Subject to the payment in full of all amounts due on or in respect of Senior Indebtedness, the Holders of the Securities shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article (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 such Senior Indebtedness to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness until the principal of and premium, if any, and Interest on the Securities shall be paid in full. For purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to 69 77 which the Holders of the Securities or the Trustee would otherwise be entitled except for the provisions of this Article, and no payments over pursuant to the provisions of this Article to the holders of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, be deemed to be a payment or distribution by the Company to or on account of the Senior Indebtedness. SECTION 1207. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS. The provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities on the one hand and the holders of Senior Indebtedness on the other hand. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Indebtedness 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 on the Securities as and when the same shall become due and payable in accordance with their terms; or (b) affect the relative rights against the Company of the Holders of the Securities and creditors of the Company other than the holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Indebtedness to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder. SECTION 1208. TRUSTEE TO EFFECTUATE SUBORDINATION. Each holder of a Security by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all such purposes. SECTION 1209. NO WAIVER OF SUBORDINATION PROVISIONS. No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article or the obligations hereunder of the Holders of the Securities to the holders of Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness, or otherwise amend or supplement in 70 78 any manner Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any Person liable in any manner for the collection of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Company and any other Person. SECTION 1210. NOTICE TO TRUSTEE. The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment to or by the Trustee in respect of the Securities. Notwithstanding the provisions of this Article 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 to or by the Trustee in respect of the Securities, unless and until the Trustee shall have received written notice thereof from the Company or a holder of Senior Indebtedness or from any trustee therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 601, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice directing that a payment or distribution not be made provided for in this Section and Section 1204 at least two Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal of and premium, if any, or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within two Business Days prior to such date. Subject to the provisions of Section 601, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness (including, without limitation, Designated Senior Indebtedness) (or a trustee or representative therefor) to establish that such notice has been given by a holder of Senior Indebtedness (including, without limitation, Designated Senior Indebtedness) (or a trustee or representative therefor). 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 to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness 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, 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 1211. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT. Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee, subject to the provisions of Section 601, and the Holders of the Securities shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which 71 79 such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article. SECTION 1212. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other Person cash, property or securities to which holders of Senior Indebtedness shall be entitled by virtue of this Article or otherwise. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Article against the Trustee. SECTION 1213. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS; PRESERVATION OF TRUSTEE'S RIGHTS. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607. SECTION 1214. ARTICLE APPLICABLE TO PAYING AGENTS. In case 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 in such case (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 Section 1213 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. SECTION 1215. CERTAIN CONVERSIONS DEEMED PAYMENT. For the purposes of this Article only, (1) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article Thirteen shall not be deemed to constitute a payment or distribution on account of the principal of or premium or interest on 72 80 Securities or on account of the purchase or other acquisition of Securities, and (2) the payment, issuance or delivery of cash (other than for payments of fractional shares pursuant to Section 1303), 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, the term "junior securities" means (a) shares of any class of capital stock of the Company and (b) securities of the Company which are subordinated in right of payment to all Senior Indebtedness 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 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 and the Holders of the Securities, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article Thirteen. SECTION 1216. NO SUSPENSION OF REMEDIES. Nothing contained in this Article shall limit the right of the Trustee or the Holders of the Securities to take any action to accelerate the maturity of the Securities pursuant to the provisions described under Article Five and as set forth in this Indenture or to pursue any rights or remedies hereunder or under applicable law, subject to the rights, if any, under this Article of the holders, from time to time, of Senior Indebtedness to receive the cash, property or securities receivable upon the exercise of such rights or remedies. ARTICLE THIRTEEN CONVERSION OF SECURITIES SECTION 1301. CONVERSION PRIVILEGE AND CONVERSION PRICE. Subject to and upon compliance with the provisions of this Article, at the option of the Holder thereof, any Security or any portion of the principal amount thereof which equals $1,000 or any integral multiple thereof may be converted at any time after the date of original issuance of Securities under this Indenture at the principal amount thereof, or of such portion thereof, into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100 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 expire at the close of business on December 1, 2004. In case a Security or portion thereof is called for redemption, such conversion right in respect of the Security or portion so called shall expire at the close of business on the business day next preceding the applicable Redemption Date, unless the Company defaults in making the payment due upon redemption. A Security for which a Holder has delivered a Repurchase Event purchase notice exercising the option of such holder to require the Company to repurchase such Security pursuant to Article Fourteen may be converted only if such notice is withdrawn by a written notice of withdrawal delivered by the Holder to the Company prior to the close of business on the Business Day immediately preceding the Repurchase Date. 73 81 The price at which shares of Common Stock shall be delivered upon conversion (herein called the "conversion price") shall be initially $19.00 per share of Common Stock. The conversion price shall be adjusted in certain instances as provided in Section 1304. SECTION 1302. EXERCISE OF CONVERSION PRIVILEGE. In order to exercise the conversion privilege, the Holder of any Security shall surrender such Security, duly endorsed or assigned to the Company or in blank, at any office or agency of the Company maintained pursuant to Section 1002, accompanied by written notice to the Company in the form provided in the Security (or such other notice as is acceptable to the Company) at such office or agency that the Holder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted. Securities surrendered for conversion during the period after any Regular Record Date next preceding any Interest Payment Date to the close of business on the Business Day immediately preceding such Interest Payment Date shall (unless such Security or portion thereof being converted shall have been called for redemption during the period from the close of business on such Regular Record Date to the close of business on the second Business Day next succeeding the following Interest Payment Date, as described in the succeeding sentence) be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount being surrendered for conversion; provided, however, that no such payment need be made if there shall exist at the time of conversion a default in the payment of interest on the Security. If such Security or portion thereof being converted shall have been called for redemption during the period from the close of business on the Regular Record Date to the close of business on the second Business Day next succeeding the following Interest Payment Date, then such Security or portion thereof shall be accompanied by payment in funds acceptable to the Company of an amount equal to the difference between (i) the interest on the principal amount of such Security or portion thereof payable on such Interest Payment Date and (ii) the amount of accrued interest on the principal amount of such Security or portion thereof to but not including the date of conversion. Except as provided above in this Section 1302 and subject to the fourth paragraph of Section 307, no payment or adjustment shall be made upon any conversion on account of any interest accrued on the Securities surrendered for conversion or on account of any dividends on the Common Stock issued upon conversion. 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 Common Stock issuable upon conversion shall be treated for all purposes of the record holder or holders of such Common Stock as and after such time. As promptly as practicable on or after the conversion date, the Company shall issue and shall deliver at such office or agency 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 1303. 74 82 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 aggregate principal amount equal to the unconverted portion of the principal amount of such Security. SECTION 1303. FRACTIONS OF SHARES. No fractional share of Common Stock shall be issued upon conversion of 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 otherwise be issuable upon conversion of any Security or Securities (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the Closing Price (as hereinafter defined) at the close of business on the day of conversion (or, if such day is not a Trading Day (as hereafter defined), on the Trading Day immediately preceding such day). SECTION 1304. ADJUSTMENT OF CONVERSION PRICE. (a) In case the Company shall pay or make a dividend or other distribution on the Common Stock exclusively in Common Stock or shall pay or make a dividend or other distribution on any other class of capital stock of the Company which dividend or distribution includes Common Stock, the conversion price in effect at the opening of business on the day 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 of which the numerator 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 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. For the purpose of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. (b) Subject to paragraph (g) of this Section, in case the Company shall pay or make a dividend or other distribution on the Common Stock consisting exclusively of, or shall otherwise issue to all holders of the Common Stock, rights or warrants entitling the holders thereof to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price (determined as provided in paragraph (j) of this Section) on the date fixed for the determination of stockholders entitled to receive such rights or warrants, the conversion price in effect at the opening of business on the day following the date fixed for such determination shall be reduced by multiplying such conversion price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or 75 83 purchase would purchase at such Current Market Price and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase, such reduction to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (b), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company shall not issue any rights or warrants in respect of shares of Common Stock held in the treasury of the Company. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received 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. (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the conversion price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and, conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the conversion price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which subdivision or combination becomes effective. (d) Subject to the last sentence of this paragraph (d) and to paragraph (g) of this Section, in case the Company shall, by dividend or otherwise, distribute to all holders of the Common Stock evidences of its indebtedness, shares of any class of its capital stock, cash or other assets (including securities, but excluding any rights or warrants referred to in paragraph (b) of this Section, excluding any dividend or distribution paid exclusively in cash and excluding any dividend or distribution referred to in paragraph (a) of this Section), the conversion price shall be reduced by multiplying the conversion price in effect immediately prior to the close of business on the date fixed for the determination of stockholders entitled to such distribution by a fraction of which the numerator shall be the Current Market Price (determined as provided in paragraph (j) of this Section) on such date less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) on such date of the portion of the evidences of indebtedness, shares of capital stock, cash and other assets to be distributed applicable to one share of Common Stock and the denominator shall be such Current Market Price, such reduction to become effective immediately prior to the opening of business on the day following such date. If the Board of Directors determines the fair market value of any distribution for purposes of this paragraph (d) by reference to the actual or when-issued trading market for any securities comprising part or all of such distribution, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price pursuant to paragraph (j) of this Section, to the extent possible. For purposes of this paragraph (d), any dividend or distribution that includes shares of Common Stock, rights or warrants to subscribe for or purchase shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock shall be deemed to be (x) a dividend or distribution of 76 84 the evidences of indebtedness, cash, assets or shares of capital stock other than such shares of Common Stock, such rights or warrants or such convertible or exchangeable securities (making any conversion price reduction required by this paragraph (d)) immediately followed by (y) in the case of such shares of Common Stock or such rights or warrants, a dividend or distribution thereof (making any further conversion price reduction required by paragraph (a) and (b) of this Section, except 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 paragraph (a) of this Section), or (z) in the case of such convertible or exchangeable securities, a dividend or distribution of the number of shares of Common Stock as would then be issuable upon the conversion or exchange thereof, whether or not the conversion or exchange of such securities is subject to any conditions (making any further conversion price reduction required by paragraph (a) of this Section, except the shares deemed to constitute 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 paragraph (a) of this Section). (e) In case the Company shall, by dividend or otherwise, at any time distribute to all holders of the Common Stock cash (excluding any cash that is distributed as part of a distribution referred to in paragraph (d) of this Section or in connection with a transaction to which Section 1311 applies) in an aggregate amount that, together with (A) the aggregate amount of any other distributions to all holders of the Common Stock made exclusively in cash within the 12 months preceding the date fixed for the determination of stockholders entitled to such distribution and in respect of which no conversion price adjustment pursuant to this paragraph (e) has been made previously and (B) the aggregate of any cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) as of such date of determination of consideration payable in respect of any tender offer by the Company or a Subsidiary for all or any portion of the Common Stock consummated within the 12 months preceding such date of determination and in respect of which no conversion price adjustment pursuant to paragraph (f) of this Section has been made previously, exceeds the greater of (I) 10.0% of the product of the Current Market Price (determined as provided in paragraph (j) of this Section) on such date of determination times the number of shares of Common Stock outstanding on such date or (II) the Company's retained earnings on the date fixed for determining the stockholders entitled to such distribution the conversion price shall be reduced by multiplying the conversion price in effect immediately prior to the close of business on such date of determination by a fraction of which the numerator shall be the Current Market Price (determined as provided in paragraph (j) of this Section) on such date less the amount of cash to be distributed at such time applicable to one share of Common Stock and the denominator shall be such Current Market Price, such reduction to become effective immediately prior to the opening of business on the day after such date. (f) In case a tender offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall be consummated and such tender offer shall involve an aggregate consideration having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) as of the last time (the "Expiration Time") that tenders may be made pursuant to such tender offer (as it shall have been amended) that, together with (A) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in 77 85 a Board Resolution) as of the Expiration Time of the other consideration paid in respect of any other tender offer by the Company or a Subsidiary for all or any portion of the Common Stock consummated within the 12 months preceding the Expiration Time and in respect of which no conversion price adjustment pursuant to this paragraph (f) has been made previously and (B) the aggregate amount of any distributions to all holders of the Common Stock made exclusively in cash within the 12 months preceding the Expiration Time and in respect of which no conversion price adjustment pursuant to paragraph (e) of this Section has been made previously, exceeds the greater of (I) 10.0% of the product of the Current Market Price (determined as provided in paragraph (j) of this Section) immediately prior to the Expiration Time times the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time or (II) the Company's retained earnings as of the Expiration Time, the conversion price shall be reduced by multiplying the conversion price in effect immediately prior to the Expiration Time by a fraction of which the numerator shall be (x) the product of the Current Market Price (determined as provided in paragraph (j) of this Section) immediately prior to the Expiration Time times the number of shares of Common Stock outstanding (including any tendered shares at the Expiration Time minus (y) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders upon consummation of such tender offer and the denominator shall be the product of (A) such Current Market Price times (B) such number of outstanding shares at the Expiration Time minus the number of shares accepted for payment in such tender offer (the "Purchased Shares"), such reduction to become effective immediately prior to the opening of business on the day following the Expiration Time; provided, that if the number of Purchased Shares or the aggregate consideration payable therefor have not been finally determined by such opening of business, the adjustment required by this paragraph (f) shall, pending such final determination, be made based upon the preliminarily announced results of such tender offer, and, after such final determination shall have been made, the adjustment required by this paragraph (f) shall be made based upon the number of Purchased Shares and the aggregate consideration payable therefor as so finally determined. (g) In case of a tender or exchange offer made by a Person other than the Company or any Subsidiary for an amount which increases the offeror's ownership of Common Stock to more than 25% of the Common Stock outstanding and shall involve the payment by such person 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 resolution of the Board of Directors) at the last time (the "Offer Expiration Time") tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) that exceeds the Current Market Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time, and in which, as of the Offer Expiration Time the Board of Directors is not recommending rejection of the offer, 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 Offer 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 Offer Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Offer 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 Offer 78 86 Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Offer Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Offer Purchased Shares) on the Offer Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time, such reduction to become effective immediately prior to the opening of business on the day following the Offer Expiration Time. In the event that such person is obligated to purchase shares pursuant to any such tender or exchange offer, but such person 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. Notwithstanding the foregoing, the adjustment described in this Section 1304 shall not be made if, as of the Offer Expiration Time, the offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Article Eight. (h) In case the Company shall issue Common Stock or securities convertible into, or exchangeable for, Common Stock at a price per share (or having a conversion or exchange price per share) that is less than the then Current Market Price of the Common Stock (but excluding, among other things, issuances: (a) pursuant to any bona fide plan for the benefit of employees, directors or consultants of the Company now or hereafter in effect; (b) to acquire all or any portion of a business in an arm's-length transaction between the Company and an unaffiliated third party including, if applicable, issuances upon exercise of options or warrants assumed in connection with such an acquisition; (c) in a bona fide public offering pursuant to a firm commitment underwriting (or a similar type of offering made pursuant to Rule 144A and/or Regulation S under the Securities Act) or sales at the market pursuant to a continuous offering stock program; (d) pursuant to the exercise of warrants, rights (including, without limitation, earnout rights) or options, or upon the conversion of convertible securities, which are issued and outstanding on the date hereof, or which may be issued in the future at fair value and with an exercise price or conversion price at least equal to the Current Market Price of the Common Stock at the time of issuance of such warrant, right, option or convertible security; and (e) pursuant to a dividend reinvestment plan or other plan hereafter adopted for the reinvestment of dividends or interest provided that such Common Stock is issued at a price at least equal to 95% of the Current Market Price of the Common Stock at the time of such issuance), the conversion price shall be adjusted so that the holder of each Security shall be entitled to receive, upon the conversion thereof, the number of shares of Common Stock determined by multiplying (i) the conversion price on the day immediately prior to such date of issuance by (ii) a fraction, the numerator of which shall be the sum of (A) the number of shares of Common Stock outstanding on such date and (B) the number of additional shares of Common Stock issued (or into which the convertible securities may convert), and the denominator of which shall be the sum of (1) the number of shares of Common Stock outstanding on such date and (2) the number of shares of Common Stock which the aggregate consideration receivable by the Company for the total number of shares of Common Stock so issued (or into which the convertible securities may convert) would purchase at such conversion price on such date. An adjustment made pursuant to this paragraph (h) shall be made on the next Business Day following the date on which any such issuance is made and shall be effective retroactively immediately after the close of business on such date. For purposes of this paragraph (h), the aggregate consideration receivable by the Company in connection with the issuance of shares of Common Stock or of 79 87 securities convertible into shares of Common Stock shall be deemed to be equal to the sum of the aggregate offering price (before deduction of underwriting discounts or commissions and expenses payable to third parties) of all such securities plus the minimum aggregate amount, if any, payable upon conversion of any such convertible securities into shares of Common Stock. (i) The reclassification of Common Stock into securities which include securities other than Common Stock (other than any reclassification upon a consolidation or merger to which Section 1311 applies) shall be deemed to involve (i) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be "the date fixed for the determination of stockholders entitled to such distribution" within the meaning of paragraph (d) of this Section), and (ii) a subdivision or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be "the day upon which such subdivision becomes effective" or "the day upon which such combination becomes effective," as the case may be, and "the day upon which such subdivision or combination becomes effective" within the meaning of paragraph (c) of this Section). In the event that the Company implements a stockholders' rights plan, such rights plan must provide that upon conversion of the Securities the Holders will receive, in addition to the Common Stock issuable upon such conversion, such rights whether or not such rights have been separated from the Common Stock at the time of such conversion. Rights or warrants issued by the Company to all holders of the Common Stock entitling the holders thereof to subscribe for or purchase shares of Common Stock (either initially or under certain circumstances), which rights or warrants (i) are deemed to be transferred with such shares of Common Stock, (ii) are not exercisable and (iii) are also issued in respect of future issuances of Common Stock, in each case in clauses (i) through (iii) until the occurrence of a specified event or events ("Trigger Event"), shall for purposes of this Section 1304 not be deemed issued or distributed 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 1304. If any such rights or warrants, including any such existing rights or warrants distributed prior to the date of this Indenture are subject to subsequent events, upon the occurrence of each of which such rights or warrants shall become exercisable to purchase different securities, evidences of indebtedness or other assets, then the occurrence of each such event shall be deemed to be such date of issuance and record date with respect to new rights or warrants (and a termination or expiration of the existing rights or warrants without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event with respect thereto, that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Price under this Section 1304 was made, (1) in the case of any such rights or warrant 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 80 88 holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or 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 any other provision of this Section 1304 to the contrary, rights, warrants, evidences of indebtedness, other securities, cash or other assets (including, without limitation, any rights distributed pursuant to any stockholder rights plan) shall be deemed not to have been distributed for purposes of this Section 1304 if the Company makes proper provision so that each holder of Securities who converts a Security (or any portion thereof) after the date fixed for determination of stockholders entitled to receive such distribution shall be entitled to receive upon such conversion, in addition to the shares of Common Stock issuable upon such conversions, the amount and kind of such distributions that such holder would have been entitled to receive if such holder had, immediately prior to such determination date, converted such Security into Common Stock. (j) For purposes of this Section 1304, the following terms shall have the meaning indicated: (1) "Closing Price" with respect to any securities on any day shall mean the last reported sales price regular way or, in case no such reported sale takes place on such day, the average of the reported closing bid and asked prices regular way, in either case on the New York Stock Exchange or, if the Common Stock is not listed or admitted to trading on such exchange, on the principal national securities exchange on which the Common Stock is listed or admitted to trading or, if not listed or admitted to trading on any national securities exchange, on the Nasdaq National Market or, if the Common Stock is not listed or admitted to trading on any national securities exchange or quoted on such National Market, the average of the closing bid and asked prices in the over-the-counter market as furnished by any New York Stock Exchange member firm selected from time to time by the Company for that purpose. (2) "Current Market Price" shall mean the average of the daily Closing Prices for the 10 consecutive Trading Days immediately prior to the date in question; provided, however, that (i) if the "ex" date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the conversion price pursuant to paragraph (a), (b), (c), (d), (e), (f), (g) or (h) above occurs during such 10 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, (ii) if the "ex" date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the conversion price pursuant to paragraph (a), (b), (c), (d), (e), (f), (g) or (h) above occurs on or after the "ex" date for the issuance or distribution requiring such computation and on or prior to the date 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 81 89 by which the conversion price is so required to be adjusted as a result of such other event, and (iii) if the "ex" date for the issuance or distribution requiring such computation is on or prior to the date in question, after taking into account any adjustment required pursuant to clause (ii) 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 and the fair market value on the date in question (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of paragraph (d), (e), (f) or (g) of this Section, whose determination shall be conclusive and described in a Board Resolution) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such "ex" date. For the purpose of any computation under paragraph (f) or (g) of this Section, the Current Market Price on any date shall be deemed to be the average of the daily Closing Prices for such day and the next two succeeding Trading Days; provided, however, that if the "ex" date for any event (other than the tender offer or exchange offer requiring such computation) that requires an adjustment to the conversion price pursuant to paragraph (a), (b), (c), (d), (e), (f), (g) or (h) above occurs on or after the Expiration Time or Offer Expiration Time as the case may be, for the tender offer or exchange offer requiring such computation and prior to the day in question, 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. For purposes of this paragraph, the term "'ex' date," (i) 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 Prices were obtained without the right to receive such issuance or distribution, (ii) 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 (iii) when used with respect to any tender offer 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 Offer Expiration Time, as the case may be. (3) "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 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. (k) The Company may make such reductions in the conversion price, in addition to those required by paragraphs (a), (b), (c), (d), (e), (f), (g) and (h) of this Section, as it considers to be advisable (as evidenced by a Board Resolution) in order that any event treated for federal income tax purposes as a dividend of stock or stock rights shall not be taxable to the recipients or, if that is not possible, to diminish any income taxes that are otherwise payable because of such event. 82 90 (l) No adjustment in the conversion price shall be required unless such adjustment (plus any other adjustments not previously made by reason of this paragraph (l)) would require an increase or decrease of at least 1% in the conversion price; provided, however, that any adjustments which by reason of this paragraph (l) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. (m) Notwithstanding any other provision of this Section 1304, no adjustment to the conversion price shall reduce the conversion price below the then par value per share of the Common Stock, and any such purported adjustment shall instead reduce the conversion price to such par value. The Company hereby covenants not to take any action to increase the par value per share of the Common Stock. SECTION 1305. NOTICE OF ADJUSTMENTS OF CONVERSION PRICE. Whenever the conversion price is adjusted as herein provided: (a) the Company shall compute the adjusted conversion price in accordance with Section 1304 and shall prepare an Officers' Certificate signed by the Treasurer of the Company setting forth the adjusted conversion price and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed (with a copy to the Trustee) at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 1002; and (b) a notice stating that the conversion price has been adjusted and setting forth the adjusted conversion price shall forthwith be prepared, and as soon as practicable after it is prepared, such notice shall be mailed by the Company to all Holders at their last addresses as they shall appear in the Security Register. Unless and until a Responsible Officer of the Trustee shall have received an Officer's Certificate setting forth an adjustment in the conversion price, the Trustee may assume without injury that no such adjustment has been made and that the last conversion price of which it has received notice remains in effect. SECTION 1306. NOTICE OF CERTAIN CORPORATE ACTION. In case: (a) the Company shall declare a dividend (or any other distribution) on its Common Stock payable (i) otherwise than exclusively in cash or (ii) exclusively in cash in an amount that would require a conversion price adjustment pursuant to paragraph (e) of Section 1304; or (b) the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights (excluding shares of capital stock or option for capital stock issued pursuant to a benefit plan for employees, officers or directors of the Company); or 83 91 (c) of any reclassification of the Common Stock (other than a subdivision or combination of the outstanding shares of Common Stock), or of any consolidation, merger or share exchange 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 shall commence a tender offer for all or a portion of the outstanding shares of Common Stock (or shall amend any such tender offer to change the maximum number of shares being sought or the amount or type of consideration being offered therefor); then the Company shall cause to be filed (with a copy to the Trustee) at each office or agency maintained pursuant to Section 1002, and shall cause to be mailed to all Holders at their last addresses as they shall appear in the Security Register, at least 21 days (or 11 days in any case specified in clause (a), (b) or (e) above) prior to the applicable record, effective or expiration date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or granting of rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record who will be entitled to such dividend, distribution, rights or warrants are to be determined, (y) the date on which such reclassification, consolidation, merger, share exchange, sale, transfer, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, share exchange, sale, transfer, dissolution, liquidation or winding up, or (z) the date on which such tender offer commenced, the date on which such tender offer is scheduled to expire unless extended, the consideration offered and the other material terms thereof (or the material terms of any amendment thereto). Neither the failure to give any such notice nor any defect therein shall affect the legality or validity of any action described in clauses (a) through (e) of this Section 1306. SECTION 1307. COMPANY TO RESERVE COMMON STOCK. The Company shall at all times reserve and keep available, free from preemptive rights, out of the authorized but unissued Common Stock or out of the Common Stock held in treasury, for the purpose of effecting the conversion of Securities, the full number of shares of Common Stock then issuable upon the conversion of all outstanding Securities. Shares of Common Stock issuable upon conversion of outstanding Securities shall be issued out of the Common Stock held in Treasury to the extent available. SECTION 1308. TAXES ON CONVERSIONS. The Company will pay any and all taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The Company 84 92 shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of any such tax, or has established to the satisfaction of the Company that such tax has been paid. SECTION 1309. COVENANT AS TO COMMON STOCK. The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and nonassessable and, except as provided in Section 1308, the Company will pay all taxes, liens and charges with respect to the issue thereof. SECTION 1310. CANCELLATION OF CONVERTED SECURITIES. All Securities delivered for conversion shall be delivered to the Trustee to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 309. SECTION 1311. PROVISIONS OF CONSOLIDATION, MERGER OR SALE OF ASSETS. In case of any consolidation of the Company with, or merger of the Company into, any other Person, 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 shares of Common Stock) or any sale or transfer of all or substantially all of the assets of the Company, the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then Outstanding shall have the right thereafter, during the period such Security shall be convertible as specified in Section 1301, to convert such Security only into the kind and amount of securities, cash and other property, if any, receivable upon such consolidation, merger, sale or transfer by a holder of the number of shares of Common Stock into which such Security might have been converted immediately prior to such consolidation, merger, sale or transfer, assuming such holder of Common Stock (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 held immediately prior to such consolidation, merger, sale or transfer by other than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised ("nonelecting share"), then for the purpose of this Section the kind and amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer by each nonelecting share shall be deemed to be the kind and amount so receivable per share by a plurality of the nonelecting 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 85 93 provided for in this Article. The above provisions of this Section shall similarly apply to successive consolidations, mergers, sales or transfers. SECTION 1312. TRUSTEE'S DISCLAIMER. The Trustee and any other conversion agent shall not at any time be under any duty or responsibility to any holder of Securities to determine whether any facts exist that may require any adjustment of the conversion price or notice thereof, or with respect to the nature or extent or calculation 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 and shall be protected in relying upon the Officers' Certificate with respect thereto which the Company is required to file with the Trustee pursuant to Section 1305. The Trustee and any other conversion agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, that may at any time be issued or delivered upon the conversion of any Security; and the Trustee and any other conversion agent make no representations with respect thereto or any actions or omission by the Company in such regard. Neither the Trustee nor any conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any debenture for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article Thirteen. The Trustee shall not be under any responsibility to determine or verify the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 1311, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 1311. ARTICLE FOURTEEN RIGHT TO REQUIRE REPURCHASE SECTION 1401. RIGHT TO REQUIRE REPURCHASE. In the event that there shall occur a Repurchase Event (as defined in Section 1406), then each Holder shall have the right, at such Holder's option, to require the Company to purchase, and upon the exercise of such right, the Company shall, subject to the provisions of Section 1203, purchase, all or any part of such Holder's Securities on the date (the "Repurchase Date") that is 30 days after the date the Company gives notice of the Repurchase Event as contemplated in Section 1402(a) at a price (the "Repurchase Price") equal to 100% of the principal amount thereof, together with accrued and unpaid interest and Liquidated Damages, if any, to the Repurchase Date. 86 94 SECTION 1402. NOTICE; METHOD OF EXERCISING REPURCHASE RIGHT. (a) On or before the 15th day after the occurrence of a Repurchase Event, the Company, or at the written request of the Company received by the Trustee at least 40 days prior to the Repurchase Date, the Trustee (in the name and at the expense of the Company), in its capacity as tender agent (for which services it shall be reasonably compensated), shall give notice of the occurrence of the Repurchase Event and of the repurchase right set forth herein arising as a result thereof by first-class mail, postage prepaid, to the Trustee and to each Holder of the Securities at such Holder's address appearing in the Security Register. The Company shall also deliver a copy of such notice of a repurchase right to the Trustee. Each notice of a repurchase right shall state: (1) the event constituting the Repurchase Event and the date thereof, (2) the Repurchase Date, (3) the date by which the repurchase right must be exercised, (4) that such repurchase right, once exercised, may be withdrawn on or prior to the close of business on the Business Day immediately prior to the Repurchase Date. (5) the Repurchase Price, and (6) the instructions a Holder must follow to exercise a repurchase right. No failure of the Company to give the foregoing notice shall limit any Holder's right to exercise a repurchase right. The Trustee shall have no affirmative obligation to determine if there shall have occurred a Repurchase Event. (b) To exercise a repurchase right, a Holder shall deliver to the Company (or an agent designated by the Company for such purpose in the notice referred to in (a) above) and to the Trustee on or before the close of business on the Repurchase Date (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 Security or Securities (or portion of a Security) to be repurchased, and a statement that an election to exercise the repurchased right is being made thereby, and (ii) the Security or Securities with respect to which the repurchase right is being exercised, duly endorsed for transfer to the Company. The repurchase right, once exercised by such Holder, may be withdrawn on or prior to the close of business on the Business Day immediately prior to the Repurchase Date. If the Repurchase Date falls between any Regular Record Date and the next succeeding Interest Payment Date, Securities to be repurchased must be accompanied by payment from the Holder of an amount equal to the interest thereon which the registered Holder thereof is to receive on such Interest Payment Date. In the event a repurchase right shall be exercised in accordance with the terms hereof, the Company shall on the Repurchase Date pay or cause to be paid in cash to the Holder thereof the Repurchase Price of the Security or Securities as to which the repurchase right had been 87 95 exercised. In the event that a repurchase right is exercised with respect to less than the entire principal amount of a surrendered Security, the Company shall execute and deliver to the Trustee and the Trustee shall authenticate for issuance in the name of the Holder a new Security or Securities in the aggregate principal amount of the unrepurchased portion of such surrendered security. SECTION 1403. DEPOSIT OF REPURCHASE PRICE. On or prior to 10:00 a.m. (New York City time) on any Repurchase Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in same day funds sufficient to pay the Repurchase Price of the Securities which are to be repaid on the Repurchase Date. SECTION 1404. SECURITIES NOT REPURCHASED ON REPURCHASE DATE. If any Security surrendered for repurchase shall not be so paid on the Repurchase Date, the principal shall, until paid, bear interest to the extent permitted by applicable law from the Repurchase Date at the rate per annum borne by such Security. SECTION 1405. SECURITIES REPURCHASED IN PART. Any Security which is to be repurchased only in part shall be surrendered at any office or agency of the Company designated for that purpose pursuant to Section 1002 (with, if the Company or the Trustee so requires, due endorsement by, or 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 deliver to the Holder of such Security without service charge, a new Security or Securities of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Security so surrendered. SECTION 1406. CERTAIN DEFINITIONS. For purposes of this Article: (a) A "Repurchase Event" shall have occurred upon the occurrence of a Change in Control or Termination of Trading after the date of this Indenture.

(c) A "Termination of Trading" shall occur if the Common Stock (or other common stock into which the Securities are then convertible) is neither listed for trading on a U.S. national securities exchange nor approved for trading on an established automated over-the-counter trading market in the United States. This instrument may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. SECTION 1407. 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 1311 applies, in which the Common Stock of the Company is changed or exchanged as a result into the right to receive securities, cash or other property 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 change or exchange becomes effective in 89 97 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, consolidation, sale or transfer, 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 Repurchase Event, including without limitation the applicable provisions of this Article Fourteen and the definitions of the Common Stock and Change of Control, as appropriate, and such other related definitions set forth herein as determined in good faith by the Company and the Company (which determination shall be conclusive and binding), to make such provisions apply in the event of a subsequent Repurchase Event 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). 90 98 IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed as of the day and year first above written.
