Whenever in this Security there is a reference, in any context, to the payment of the principal of, premium, if any, or interest on, or in respect of, this Security such mention shall be deemed to include mention of the payment of Liquidated Damages payable as described in the - 23 - 34 preceding paragraph to the extent that, in such context, Liquidated Damages are, were or would be payable in respect of this Security pursuant to such paragraph, and an express mention of the payment of Liquidated Damages (if applicable) in any provisions of this Security shall not be construed as excluding Liquidated Damages in those provisions of this Security where such express mention is not made. [If this Security is a Registrable Security and the Holder of this Security [IF THIS SECURITY IS A GLOBAL SECURITY, THEN INSERT - (including any Person that has a beneficial interest in this Security)] elects to sell this Security pursuant to the Shelf Registration Statement then, by his acceptance hereof, such Holder of this Security agrees to be bound by the terms of the Registration Rights Agreement relating to the Registrable Securities which are the subject of such election.] Under certain circumstances involving a Change in Control (as defined in the Indenture), the Company may be required to offer to purchase the Securities at a purchase price equal to 100% of the principal amount of such Securities, together with accrued and unpaid interest to the Repurchase Date.

For purposes of this paragraph, the fair market value of shares of Common Stock shall be determined by the Company and shall be equal to 95% of the average of the Closing Prices per share for the five consecutive Trading Days immediately preceding the second Trading Day prior to the Repurchase Date. Whenever in this Security there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to the Repurchase Price payable in respect of such Security to the extent that such Repurchase Price is, was or would be so payable at such date, and express mention of the Repurchase Price in any provision of this Security shall not be construed as excluding the Repurchase Price so payable in those provisions of this Security when such express mention is not made; provided, however, that, for the purposes of the second succeeding paragraph, such reference shall be deemed to include reference to the Repurchase Price only to the extent the Repurchase Price is payable in cash.

The Indenture also contains provisions permitting the Holders of at least a majority 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 herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. The Indenture provides that no Holder of any Security may enforce any remedy under the Indenture except in the case of failure of the Trustee to act after notice of default and after request by the Holders of 25% in aggregate principal amount of the Outstanding Securities and the offer and, if requested, provision to the Trustee of reasonable indemnity satisfactory to the Trustee; provided, however, that such provision shall not prevent the Holder hereof from enforcing payment of the principal of (and premium, if any) or interest on this Security after the same shall have become due.

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 the 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 authenticate and deliver such Securities as in this Indenture provided and not otherwise.

Section 304. Global Securities; Non-Global Securities. (A) Global Securities (a) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated by the Company for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture. (b) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (i) such Depositary (A) has - 31 - 42 notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (B) has ceased to be a clearing agency registered as such under the Exchange Act or announces an intention permanently to cease business or does in fact do so or (ii) there shall have occurred and be continuing an Event of Default with respect to such Global Security. (c) If any Global Security is to be exchanged for other Securities or cancelled in whole, it shall be surrendered by or on behalf of the Depositary or its nominee to the Trustee, as Security Registrar, for exchange or cancellation, as provided in this Article Three. If any Global Security is to be exchanged for other Securities or cancelled in part, or if another Security is to be exchanged in whole or in part for a beneficial interest in any Global Security, in each case, as provided in Section 305, then either (i) such Global Security shall be so surrendered for exchange or cancellation, as provided in this Article Three, or (ii) the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or cancelled, or equal to the principal amount of such other Security to be so exchanged for a beneficial interest therein, as the case may be, by means of an appropriate adjustment made on the records of the Trustee, as Security Registrar, whereupon the Trustee, in accordance with the Applicable Procedures, shall instruct the Depositary or its authorized representative to make a corresponding adjustment to its records. Upon any such surrender or adjustment of a Global Security, the Trustee shall, subject to Section 305(c) and as otherwise provided in this Article Three, authenticate and deliver any Securities issuable in exchange for such Global Security (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depositary or its authorized representative. Upon the request of the Trustee in connection with the occurrence of any of the events specified in the preceding paragraph, the Company shall promptly make available to the Trustee a reasonable supply of Securities that are not in the form of Global Securities. The Trustee shall be entitled to rely upon any order, direction or request of the Depositary or its authorized representative which is given or made pursuant to this Article Three if such order, direction or request is given or made in accordance with the Applicable Procedures. (d) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Article Three or otherwise, shall be authenticated and delivered in the form of, and shall be, a registered Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof, in which case such Registered Security shall be authenticated and delivered in definitive, fully registered form, without interest coupons. (e) The Depositary or its nominee, as registered owner of a Global Security, shall be the Holder of such Global Security for all purposes under the Indenture and the Registered Securities, and owners of beneficial interests in a Global Security shall hold such interests pursuant to the Applicable Procedures. Accordingly, any such owner's beneficial interest in a Global Security will be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its Agent Members and - 32 - 43 such owners of beneficial interests in a Global Security will not be considered the owners or holders thereof. (B) Non-Global Securities Regulation D Securities shall be initially issued as Registered Securities in definitive, fully registered form, without interest coupons, shall initially be registered in such names and be in such authorized denominations as Goldman, Sachs & Co. and Merrill Lynch, Pierce, Fenner & Smith Incorporated shall designate and shall bear the legends required hereunder. The Company will make available to the Trustee a reasonable supply of Registered Securities in definitive form. Pending the preparation of definitive Registered Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and make available for delivery, temporary Registered Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Registered Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Registered Securities may determine, as evidenced by their execution of such Securities. If temporary Registered Securities are issued, the Company will cause definitive Registered Securities to be prepared without unreasonable delay. After the preparation of the definitive Registered Securities, the temporary Registered Securities shall be exchangeable for definitive Registered Securities upon surrender of the temporary Registered 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 Registered Securities the Company shall execute and the Trustee shall authenticate and make available for delivery in exchange therefor a like principal amount of definitive Registered Securities of authorized denominations. Until so exchanged the temporary Registered Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Registered Securities. Section 305. Registration, Registration of Transfer and Exchange; Restrictions on Transfer. (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 of the Company 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 Registered Securities and of transfers of Registered Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Registered Securities and transfers and exchanges of Registered Securities as herein provided. Upon surrender for registration of transfer of any Security at an office or agency of the Company designated pursuant to Section 1002 for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee - 33 - 44 or transferees, one or more new Securities of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture.

Whenever any Securities are so surrendered for exchange, and subject to the other provisions of this Section 305, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and subject to the other provisions of this Section 305, entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. No service charge shall be made for any registration of transfer or exchange of Securities except as provided in Section 306, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906, 1108, 1205, or 1301 not involving any transfer and other than any stamp and other duties, if any, which may be imposed in connection with any such transfer or exchange by the United States or United Kingdom any political subdivision thereof or therein, which shall be paid by the Company. In the event of a redemption of the Securities, the Company will not be required (a) to register the transfer of or exchange Securities for a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities called for such redemption or (b) to register the transfer of or exchange any Security, or portion thereof, called for redemption.

(iv) Exchanges between Global Security and Non-Global Security. A beneficial interest in a Global Security may be exchanged for a Security that is not a Global Security as provided in Section 304, provided that, if such interest is a beneficial interest in the Restricted Global Security, or if such interest is a beneficial interest in the Regulation S Global Security and such exchange is to occur during the Restricted Period, then such interest shall be exchanged for a Restricted Security (subject in each case to Section 305(c)). A Security that is not a Global Security may be exchanged for a beneficial interest in a Global Security only if such exchange occurs in connection with a transfer effected in accordance with Clause (b)(iii) above.

The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith pursuant to instructions from the Company contemplated by the aforementioned registration statement; (iv) at any time after the Securities may be freely transferred without registration under the Securities Act or without being subject to transfer restrictions pursuant to the Securities Act, a new Security which does not bear a Securities Act Legend may be issued in exchange for or in lieu of a Security (other than a Global Security) or any portion thereof which bears such a legend if the Trustee has received an Unrestricted Securities Certificate, satisfactory to the Trustee and duly executed by the Holder of such legended Security or his attorney duly authorized in writing, and after such date and receipt of such certificate, the Trustee shall authenticate and deliver such a new Security in exchange for or in lieu of such other Security as provided in this Article Three; (v) a new Security which does not bear a Securities Act Legend may be issued in exchange for or in lieu of a Security (other than a Global Security) or any portion thereof which bears such a legend if, in the Company's judgment, placing such a legend upon such new Security is not necessary to ensure compliance with the registration requirements of the Securities Act, and the Trustee, at the direction of the Company, shall authenticate and deliver such a new Security as provided in this Article Three; and (vi) notwithstanding the foregoing provisions of this Section 305(c), a Successor Security of a Security that does not bear a particular form of Securities Act Legend shall not bear such form of legend unless the Company has reasonable cause to believe that such Successor Security is a "restricted security" within the meaning of Rule 144, in which case the Trustee, at the direction of the Company, shall authenticate and deliver a new Security bearing a Restricted Securities Legend in exchange for such Successor Security as provided in this Article Three. (d) Neither the Trustee, the Paying Agent nor any of their agents shall (1) have any duty to monitor compliance with or with respect to any federal or state or other securities or tax laws or (2) have any duty to obtain documentation on any transfers or exchanges other than as specifically required hereunder. - 37 - 48 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 actual notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon a Company Request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion, but subject to any conversion rights, may, instead of issuing a new Security, pay such Security. Upon 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 reasonable expenses (including the expenses of the Trustee) connected therewith. Every new Security issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and 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. 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 - 38 - 49 such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below: (a) 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 (b). (b) 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 next succeeding Interest Payment Date (other than any 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 - 39 - 50 business on such Regular Record Date. Upon a call for redemption by the Company, accrued and unpaid interest to the Redemption Date shall be payable with respect to Securities converted after the notice of redemption has been mailed and prior to the Redemption Date. Except as otherwise expressly provided in this paragraph, 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 and 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, repurchase, registration of transfer or exchange or conversion shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled 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 cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company Order. The Company shall, within 120 days of a request therefor by the Trustee, deliver a Company Order directing the destruction of cancelled Securities. If the Company fails to respond to such a request within such 120-day period, the Trustee may destroy any or all cancelled Securities, in which case the Trustee shall deliver a certificate as to such destruction to the Company. Section 310. Computation of Interest. Interest on the Securities (including any Liquidated Damages and additional interest) shall be computed on the basis of a 360-day year consisting of twelve 30-day months. Section 311. CUSIP Numbers. The Company in issuing Securities may use "CUSIP" numbers (if then generally in use) in addition to serial numbers, and, if so, the Trustee shall use such CUSIP numbers in addition to serial numbers in notices of redemption and repurchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of - 40 - 51 such CUSIP numbers either as printed on the Securities or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Securities, and any such redemption or repurchase shall not be affected by any defect in or omission of such CUSIP numbers. ARTICLE FOUR SATISFACTION AND DISCHARGE Section 401. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further effect (except as to any surviving rights of conversion, registration of transfer, exchange or replacement of Securities herein expressly provided for and any right to receive Liquidated Damages as provided in the form of Securities herein), and the Trustee, on demand of and 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 arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case of (i), (ii) or (iii) above, has irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust for the purpose an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for - 41 - 52 principal (and premium, if any) and interest (including any Liquidated Damages) 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; (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and (3) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 607, the obligations of the Trustee to any Authenticating Agent under Section 614 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive. Section 402. Application of Trust Money. Subject to the provisions of the last paragraph of Section 1003, 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 Paying Agent is unable to apply any money deposited with respect to the Securities in accordance with Section 401 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 401 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 401; provided, however, that if the Company has made any payment of principal of (or premium, if any) or interest on any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent. - 42 - 53 ARTICLE FIVE REMEDIES Section 501.

or (5) default under any bond, debenture, note or other evidence of indebtedness for money borrowed or under any mortgage, indenture or other instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company or under any guarantee of payment by the Company of indebtedness for money borrowed, whether such indebtedness or guarantee now exists or shall hereafter be created, which default extends beyond any period of grace provided with respect thereto and which default relates to (a) the obligation to pay the principal of or interest on any such indebtedness or guarantee or (b) an obligation other than the obligation to pay the principal of or interest on any such indebtedness, if the effect of such event of default is to cause the acceleration of a principal amount of such - 43 - 54 indebtedness and such other indebtedness or guarantee shall not have been paid within ten days after there has been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Securities a written notice specifying such event of default and stating that such notice is a "Notice of Default" hereunder; provided, however, that no default under this Section 501(5) shall exist if all such defaults do not relate to such indebtedness or such guarantees with an aggregate principal amount in excess of 5% of Consolidated Net Tangible Assets; and provided further, that if any such event of default has been cured or waived and any acceleration with respect thereto rescinded, or if such other indebtedness has been repaid or otherwise discharged, the Event of Default arising under this Section 501(5) by virtue thereof shall not be deemed to have occurred and any acceleration under this Section 501(5) pursuant to Section 502 hereof shall ipso facto be rescinded so long as such rescission does not conflict with any judgment or decree;

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 Article provided, the Holders of a majority in aggregate 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 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 or liabilities incurred by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (2) all Events of Default, other than the nonpayment of the principal of Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. No such rescission shall affect any subsequent default or impair any right consequent thereon. - 45 - 56 Section 503. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if (1) default is made in the payment of any interest (including any Liquidated Damages) 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 (and premium, if any) and interest, and, to the extent that payment of such interest shall be legally enforceable, interest (including any Liquidated Damages), on any overdue principal (and premium, if any) and on any overdue interest (including any Liquidated Damages), 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, its agents and counsel. If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company 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, being advised by counsel, 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 the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue - 46 - 57 principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, (i) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Securities, subject to the provisions of Article Fourteen, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, subject to the provisions of Article Fourteen, and (ii) subject to the provisions of Article Fourteen, 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 for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. Nothing herein contained 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. 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, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. In any such proceeding brought by the Trustee, the Trustee shall be deemed to represent all Holders without the necessity of joining any Holders as parties. Section 506. Application of Money Collected. Subject to Article Fourteen, 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 the case of the distribution of such money on account of principal (or premium, if any) or - 47 - 58 interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all costs and expenses in connection with the collection of such money and to the payment of all amounts due the Trustee under Section 607; SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest, respectively; and THIRD: Any remaining amounts shall be repaid to the Company. Section 507. Limitation on Suits.

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, subject to the subordination provisions in Article Fourteen, 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 or repurchase, on the Redemption Date or Repurchase Date, as the case may be) and to institute suit for the enforcement of any such payment and the 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. 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 the last paragraph of 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. - 49 - 60 Section 512. Control by Holders. The Holders of a majority in aggregate principal amount of the Outstanding Securities shall have the right to direct in writing the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, provided that (1) such direction shall not be in conflict with any rule of law or with this Indenture, (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, 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. This Section 512 shall be in lieu of Section 316(a)(1)(A) of the Trust Indenture Act and said Section 316(a)(1)(A) is hereby expressly excluded from this Indenture, as permitted by the Trust Indenture Act. Section 513. Waiver of Past Defaults. The Holders of not less than a majority in aggregate 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.

Whenever the Company shall have one or more Paying Agents, it will, prior to each due date of the principal of (and premium, if any) or interest on any Securities, deposit in immediately available funds with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. The Company will cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent; and (2) at any time during the continuance of any default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Security and remaining unclaimed for two years (or such shorter period as required by applicable abandonment law with respect to the Holder entitled to payment thereof) after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on - 65 - 76 Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, unless an applicable abandonment statute designates another Person, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in New York, New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. Section 1004. Existence. Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if a transaction that would result in the termination of the Company's existence or any such right or franchise is permissible under Article Eight or if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. Section 1005. Statement by Officers as to Default. The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, in each case ending after the date hereof, an Officers' Certificate, stating that a review of the activities of the Company during the preceding fiscal year has been made under the supervision of the signing officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such officer signing such certificate, that to the best of his knowledge the Company is not in default in the performance or observance of any of the terms, provisions and conditions hereof or, if a default or Event of Default shall have occurred, describing all such defaults or Events of Default of which he may have knowledge and that to the best of his knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Securities are prohibited or if such event has occurred, a description of the event. Section 1006. Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any covenant or condition set forth in Section 1004, if before the time for such compliance the Holders of at least a majority in aggregate principal amount of the Outstanding Securities shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such - 66 - 77 covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect. Section 1007. Registration Rights. The Company agrees that the Holders from time to time of Registrable Securities (as defined below) are entitled to the benefits of a Registration Rights Agreement, dated as of June 11, 1996 (the "Registration Rights Agreement"), executed by the Company. Pursuant to the Registration Rights Agreement, the Company has agreed for the benefit of the Holders from time to time of Registrable Securities to file a shelf registration statement (the "Shelf Registration Statement") with the Commission with respect to resales of the Registrable Securities. If (i) on or prior to 90 days following the date of original issuance of the Registered Securities, a Shelf Registration Statement has not been filed with the Commission, or (ii) on or prior to the 180th day following the date of original issuance of the Registered Securities, such Shelf Registration Statement is not declared effective (each, a "Registration Default"), additional interest ("Liquidated Damages") will accrue on the Registered Securities from and including the day following such Registration Default to but excluding the day on which such Registration Default has been cured. Liquidated Damages will be paid semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment Date in respect of the Registered Securities following the date on which such Liquidated Damages begin to accrue, and will accrue at a rate per annum equal to an additional one-quarter of one percent (.25%) of the principal amount of the Registered Securities to and including the 90th day following such Registration Default and at a rate per annum equal to one-half of one percent (.50%) thereof from and after the 91st day following such Registration Default. In the event that the Shelf Registration Statement ceases to be effective during the Effectiveness Period or the Company suspends the use of the prospectus which is a part thereof for a period in excess of 60 days, whether or not consecutive, during any 12-month period, then the interest rate borne by the Registered Securities shall increase by an additional one-half of one percent (.50%) per annum on the 61st day of the applicable 12-month period such Shelf Registration Statement ceases to be effective or the Company suspends the use of the prospectus which is a part thereof, as the case may be, to but excluding the day on which (i) the Shelf Registration Statement again becomes effective, (ii) the use of the related prospectus ceases to be suspended or (iii) the Effectiveness Period expires. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of, premium, if any, or interest on, or in respect of, any Registered Security, such mention shall be deemed to include mention of the payment of Liquidated Damages provided for in this Section to the extent that, in such context, Liquidated Damages are, were or would be payable in respect thereof pursuant to the provisions of this Section, and express mention of the payment of Liquidated Damages (if applicable) in any provisions hereof shall not be construed - 67 - 78 as excluding Liquidated Damages in those provisions hereof where such express mention is not made. For the purposes of the Registration Rights Agreement, "Registrable Securities" means all or any portion of the Registered Securities issued from time to time under this Indenture and the shares of Common Stock issuable upon conversion of such Securities; provided, however, that a Security or the shares of Common Stock issuable upon conversion of a Security ceases to be a Registrable Security when it (i) has been effectively registered under the Securities Act and sold in a manner contemplated by the Shelf Registration Statement, (ii) has been transferred in compliance with Rule 144 under the Securities Act (or any successor provisions thereto) or (iii) otherwise has been transferred and a new Security or share of Common Stock not subject to transfer restrictions under the Securities Act has been delivered by or on behalf of the Company in accordance with Section 305. If a Security, or the shares of Common Stock issuable upon conversion of a Security, is a Registrable Security, and the Holder thereof elects to sell such Registrable Security pursuant to the Shelf Registration Statement then, by its acceptance thereof, the Holder of such Registrable Security will have agreed to be bound by the terms of the Registration Rights Agreement relating to the Registrable Securities which are the subject of such election. For the purposes of the Registration Rights Agreement, the term "Holder" includes any Person that has a beneficial interest in any Global Security or any beneficial interest in a global security representing shares of Common Stock issuable upon conversion of a Security. Section 1008. Resale of Certain Securities: Reporting Issuer. During the period beginning on the last date of original issuance of the Securities and ending on the date that is three years from such date, the Company will not, and will not permit any of its subsidiaries or other "affiliates" (as defined under Rule 144 under the Securities Act or any successor provision thereto) controlled by the Company to, resell (x) any Securities which constitute "restricted securities" under Rule 144 or (y) any securities into which the Securities have been converted under this Indenture which constitute "restricted securities" under Rule 144, that in either case have been reacquired by any of them. The Trustee shall have no responsibility in respect of the Company's performance of its agreement in the preceding sentence. Section 1009. Payment of Certain Duties. Subject to Sections 305 and 306 hereof, the Company will pay or discharge, or cause to be paid or discharged, before the same may become delinquent, all stamps and other duties, if any, which may be imposed by the United States or United Kingdom or any political subdivision thereof or therein in connection with the issuance, transfer, exchange or conversion of any Securities or with respect to this Indenture. - 68 - 79 ARTICLE ELEVEN REDEMPTION OF SECURITIES Section 1101. Right of Redemption. The Securities may be redeemed at the election of the Company, as a whole or from time to time in part, at any time on or after June 15, 1999, at the Redemption Prices specified in the form of Security hereinbefore set forth, together with accrued interest to the Redemption Date. Section 1102. Applicability of Article. Redemption of Securities at the election of the Company or otherwise, as permitted or required by any provision of this Indenture, shall be made in accordance with such provision and this Article. Section 1103. Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities pursuant to Section 1101 shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company of less than all the Securities, the Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities to be redeemed and whether the Trustee is to give the notice of redemption. Section 1104. Selection by Trustee of Securities to Be Redeemed. If less than all the Securities are to be redeemed pursuant to Section 1101, the particular Securities to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Securities not previously called for redemption, by such method (including pro rata or by lot) as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions (equal to $1,000 or any integral multiple thereof) of the principal amount of Securities of a denomination larger than $1,000. If any Registered Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. - 69 - 80 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 each Holder of Securities to be redeemed, at his address appearing in the Security Register. All notices of redemption shall state: (1) the Redemption Date; (2) the Redemption Price; (3) if less than all the Outstanding Securities are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Securities to be redeemed; (4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and that interest thereon will cease to accrue on and after said date; (5) the conversion price, the date on which the right to convert the principal of the Securities to be redeemed will terminate and the place or places where such Securities may be surrendered for conversion; and (6) the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued interest, if any. Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at Company Request, by the Trustee in the name and at the expense of the Company. Section 1106. Deposit of Redemption Price. Prior to 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 - 70 - 81 in trust as provided in Section 1003) an amount of money in immediately available funds sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date other than any Securities called for redemption on that date which have been converted prior to the date of such deposit, in which case only accrued interest payable on such Securities pursuant to Sections 307 or 1303 need be so deposited. 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 the right of the Holder of such Security or any Predecessor Security to receive interest as provided in the last paragraph of Section 307 or in Section 1303) 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 interest to the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) and, to the extent permitted by applicable law, any overdue interest thereon shall, until paid, bear interest from the Redemption Date at the rate borne by the Security, and such Security shall remain convertible until the principal thereof shall have been paid or duly provided for. 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 designated for that purpose pursuant to Section 1002 (with, if the Company or 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. - 71 - 82 ARTICLE TWELVE RIGHT TO REQUIRE REPURCHASE Section 1201. Right to Require Repurchase. (a) In the event that there shall occur a Change in Control (as defined in Section 1206) which constitutes a Repurchase Event (as defined in Section 1206), 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 Article Fourteen, purchase all or any part of such Holder's Securities on a date (the "Repurchase Date") selected by the Company that is not more than 75 days after the date the Company gives notice of the Repurchase Event as contemplated in Section 1202(a) at a price (the "Repurchase Price") equal to 100% of the principal amount thereof, together with accrued and unpaid interest to the Repurchase Date. At the option of the Company, the Repurchase Price may be paid in cash or, subject to the fulfillment by the Company of the conditions set forth in clause (b) of this Section 1201, by delivery of shares of Common Stock having a fair market value equal to the Repurchase Price. (b) The Company may elect to pay the Repurchase Price by delivery of shares of Common Stock pursuant to clause (a) of this Section 1201 if and only if the following conditions shall have been satisfied: (1) The shares of Common Stock deliverable in payment of the Repurchase Price shall have a fair market value as of the Repurchase Date of not less than the Repurchase Price. For purposes of this Section 1201, the fair market value of shares of Common Stock shall be determined by the Company and shall be equal to 95% of the average of the Closing Prices per share for the five consecutive Trading Days immediately preceding the second Trading Day prior to the Repurchase Date; (2) The Repurchase Price shall be paid only in cash in the event any shares of Common Stock to be issued upon repurchase of Securities hereunder (i) require registration under any federal securities law before such shares may be freely transferable without being subject to any transfer restrictions under the Securities Act upon repurchase and if such registration is not completed or does not become effective prior to the Repurchase Date, and/or (ii) require registration with or approval of any governmental authority under any state law or any other federal law before such shares may be validly issued or delivered upon repurchase and if such registration is not completed or does not become effective or such approval is not obtained prior to the Repurchase Date; (3) Payment of the Repurchase Price may not be made in Common Stock unless such stock is, or shall have been, approved for listing on the New York - 72 - 83 Stock Exchange or listed on another national securities exchange or quoted on the Nasdaq National Market System, in either case, prior to the Repurchase Date; and (4) All shares of Common Stock which may be issued upon repurchase of Securities will be issued out of the Company's authorized but unissued Common Stock and, will upon issue, be duly and validly issued and fully paid and non-assessable and free of any preemptive rights. (c) If all of the conditions set forth in Section 1201(b) are not satisfied in accordance with the terms thereof, the Repurchase Price shall be paid by the Company only in cash. Section 1202. Notice; Method of Exercising Repurchase Right. (a) On or before the 15th day after the Repurchase Event, the Company, or at Company Request, the Trustee (in the name and at the expense of the Company), shall give notice (the "Company 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 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) the Repurchase Price, and whether the Repurchase Price shall be paid by the Company in cash or by delivery of shares of Common Stock, (5) 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 Business Day immediately preceding 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 - 73 - 84 a Security) to be repurchased, and a statement that an election to exercise the repurchase right is being made thereby, and (ii) the Security or Securities with respect to which the repurchase right is being exercised. Such written notice shall be irrevocable. 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. (c) In the event a repurchase right shall be exercised in accordance with the terms hereof, then subject to Article Fourteen, the Company shall pay or cause to be paid to the Trustee the Repurchase Price in cash or shares of Common Stock, as provided above, for payment to the Holder on the Repurchase Date or, if shares of Common Stock are to be paid, as promptly after the Repurchase Date as practicable, together with accrued and unpaid interest to the Repurchase Date payable with respect to the Securities as to which the purchase right has been exercised; provided, however, that installments of interest that mature on or prior to the Repurchase Date shall be payable in cash to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Date. 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. (d) Any issuance of shares of Common Stock in respect of the Repurchase Price shall be deemed to have been effected immediately prior to the close of business on the Repurchase Date and the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such repurchase shall be deemed to have become on the Repurchase Date the holder or holders of record of the shares represented thereby; provided, however, that any surrender for repurchase on a date when the stock transfer books of the Company shall be closed shall constitute the Person or Persons in whose name or names the certificate or certificates for such share are to be issued as the record holder or holders thereof for all purposes at the opening of business on the next succeeding day on which such stock transfer books are open. No payment or adjustment shall be made for dividends or distributions on any Common Stock issued upon repurchase of any Security declared prior to the Repurchase Date. (e) No fractions of shares shall be issued upon repurchase of Securities. If more than one Security shall be repurchased from the same Holder and the Repurchase Price shall be payable in shares of Common Stock, the number of full shares which shall be issuable upon such repurchase shall be computed on the basis of the aggregate principal amount of the Securities so repurchased. Instead of any fractional share of Common Stock which would otherwise be issuable on the repurchase of any Security or Securities, the Company will deliver to the applicable Holder its check for the current market value of such fractional share. The current market value of a fraction of a share is determined by multiplying the current market price of a full share by the fraction, and rounding the result to the nearest cent. For purposes of - 74 - 85 this Section, the current market price of a share of Common Stock is the Closing Price per share of the Common Stock on the Trading Day immediately preceding the Repurchase Date. (f) Any issuance and delivery of certificates of shares of Common Stock on repurchase of Securities shall be made without charge to the Holder of Securities being repurchased for such certificates or for any tax or duty in respect of the issuance or delivery of such certificates or the securities represented thereby; provided, however, that the Company shall not be required to pay any tax or duty which may be payable in respect of (i) income of the Holder or (ii) any transfer involved in the issuance or delivery of certificates for shares of Common Stock in a name other than that of the Holder of the Securities being repurchased, and no such issuance or delivery shall be made unless and until the Person requesting such issuance or delivery has paid to the Company the amount of any such tax or duty or has established, to the satisfaction of the Company, that such tax or duty has been paid. (g) If shares of Common Stock to be delivered upon repurchase of a Restricted Security are to be registered in a name other than that of the beneficial owner of such Security, then such Holder must deliver to the Trustee a Surrender Certificate, dated the date of surrender of such Restricted Security and signed by such beneficial owner, as to compliance with the restrictions on transfer applicable to such Restricted Security. Neither the Trustee nor any Registrar or Transfer Agent or other agents shall be required to register in a name other than that of the beneficial owner shares of Common Stock issued upon repurchase of any such Restricted Security not so accompanied by a properly completed Surrender Certificate. Section 1203. Deposit of Cash Repurchase Price. If all or part of the Repurchase Price is to be paid in cash, on or prior to the Repurchase Date and subject to Article Fourteen, 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 immediately available funds, sufficient to pay the cash portion of the Repurchase Price of the Securities which are payable on the Repurchase Date, plus accrued interest thereon. Section 1204. Securities Not Repurchased on Repurchase Date. If any Security surrendered for repurchase shall not be paid on the Repurchase Date, the principal and any overdue interest thereon shall, until paid, bear interest to the extent permitted by applicable law from the Repurchase Date at a rate per annum borne by such Security, and such Security shall remain convertible until the principal thereof shall have been paid or duly provided for. Section 1205. 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 - 75 - 86 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 repurchased portion of the principal of the Security so surrendered. Section 1206. "Change in Control" and "Repurchase Event" Defined. (a) For purposes of this Article, "Change in Control" means any of the following events that occurs after the Issue Date of the Securities and so long as any Securities are Outstanding: (1) the Company's assets are sold or otherwise disposed of substantially as an entirety to any Person or related group of Persons in any one transaction or a series of related transactions; (2) there shall be consummated any consolidation or merger of the Company (A) in which the Company is not the continuing or surviving corporation (other than a consolidation or merger with a wholly-owned Subsidiary of the Company in which all shares of Common Stock outstanding immediately prior to the effectiveness thereof are changed into or exchanged for the same number of shares of common stock of such Subsidiary) or (B) pursuant to which the Common Stock is converted into cash, securities or other property, in each case other than a consolidation or merger of the Company in which the holders of the Common Stock immediately prior to the consolidation or merger have, directly or indirectly, at least a majority of the common stock of the continuing or surviving Corporation immediately after such consolidation or merger; or (3) any Person, or any Persons acting together which would constitute a "group" for purposes of Section 13(d) of the Exchange Act (a "Group") (other than the Company, any Subsidiary, any employee stock purchase plan, stock option plan or other stock incentive plan or program, retirement plan or automatic dividend reinvestment plan or any substantially similar plan of the Company or any Subsidiary or any Person holding securities of the Company for or pursuant to the terms of any such employee benefit plan, which may file or become obligated to file a report under or in response to Schedule 13D or Schedule 14D-1 (or any successor schedule, form or report) under the Exchange Act), together with any Affiliates thereof, shall acquire beneficial ownership (as defined in Rule 13d-3 of the Exchange Act) of at least 50% of the total voting power of all classes of capital stock of the Company entitled to vote generally in the election of directors of the Company. - 76 - 87 (b) A Change in Control as described in Section 1206(a) shall constitute a "Repurchase Event" giving rise to a repurchase right on the part of each Holder of a Security unless: (1) the Current Market Price of the Common Stock on the date the Change in Control shall have occurred is at least equal to 105% of the conversion price in effect immediately preceding the time of such Change in Control, or (2) all of the consideration (excluding cash payments for fractional shares) in the transaction giving rise to such Change in Control to the holders of Common Stock consists of shares of common stock that are, or immediately upon issuance will be, listed on a national securities exchange or quoted in the NASDAQ National Market System, and as a result of such transaction the Securities become convertible solely into such shares of common stock, or (3) the consideration in the transaction giving rise to such Change in Control to the holders of Common Stock consists of cash, securities that are, or immediately upon issuance will be, listed on a national securities exchange or quoted in the NASDAQ National Market System, or a combination of cash and such securities and the aggregate fair market value of such consideration (which, in the case of each such security, shall be equal to the average of the daily Closing Prices of each such security during the 10 consecutive Trading Days commencing with the sixth Trading Day following consummation of such transaction) to be received by a holder of Common Stock with respect to one share of Common Stock is at least 105% of the conversion price in effect on the date immediately preceding the closing date of such transaction. For purposes of this definition, "Current Market Price" on any date means the average daily Closing Prices for the 5 consecutive Trading Days selected by the Company commencing not more than 10 Trading Days before, and ending not later than, the date in question. ARTICLE THIRTEEN CONVERSION OF SECURITIES Section 1301. Right of Conversion. The Holder of any Security or Securities shall have the right at any time on or after 90 days from the last original issuance date of the Securities and prior to the close of business on the maturity date, subject, in the case of conversion of any Global Security, to any Applicable Procedures, at his option, to convert, subject to the terms and provisions of this Article Thirteen, the principal of any such Security or Securities (or any portion of the principal thereof which is $1,000 or an integral multiple of $1,000) into fully paid and nonassessable shares - 77 - 88 of Common Stock of the Company at the conversion price of $42.185 of principal amount of Securities per share of Common Stock or, in case an adjustment therein has taken place pursuant to the provisions of Section 1304, then at the price as so adjusted (except that with respect to any Security or Securities, or any such portion, which shall be called for redemption, such right shall terminate, except as provided in the last paragraph of Section 1302, at the close of business on the Business Day immediately preceding the Redemption Date for such Security or Securities or portion unless the Company shall default in payment due upon redemption thereof). Such right shall be exercised by the surrender of the Security or Securities, the principal of which is so to be converted, to the Company at any time during usual business hours at any office or agency to be maintained by it in accordance with the provisions of Section 1002, accompanied by written notice that the Holder elects to convert such Security or Securities or any portion thereof and specifying the name or names (with address) in which a certificate or certificates for Common Stock are to be issued and (if so required by the Company or the Trustee) by a written instrument or instruments of transfer in form satisfactory to the Company and the Trustee, duly executed by the Holder or his attorney, duly authorized in writing and transfer tax stamps or funds therefor, if required pursuant to Section 1310. For convenience, the conversion of all or a portion, as the case may be, of the principal of any Security into the Common Stock of the Company is hereinafter sometimes referred to as the conversion of such Security. All Securities surrendered for conversion shall, if surrendered to the Company or any conversion agent, be delivered to the Trustee for cancellation and cancelled by it or, if surrendered to the Trustee, shall be cancelled by it; and, subject to the next succeeding sentence, no Securities shall be issued in lieu thereof. In the case of any Security which is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Security or Securities of authorized denominations in an aggregate principal amount equal to the unconverted portion of the principal amount of such Security. Section 1302. Issuance of Common Stock; Time of Conversion. As promptly as practicable after the surrender, as herein provided, of any Security or Securities for conversion, the Company shall deliver or cause to be delivered at any office or agency to be maintained by it in accordance with the provisions of Section 1002 to or upon the written order of the Holder of the Security or Securities so surrendered a certificate or certificates representing the number of fully paid and nonassessable shares of Common Stock of the Company into which such Security or Securities (or portion thereof) may be converted in accordance with the provisions of this Article Thirteen. Subject to the following provisions of this paragraph and of Section 1304, such conversion shall be deemed to have been made immediately prior to the close of business on the date that such Security or Securities shall have been surrendered in satisfactory form for conversion, so that the rights of the Holder as a Holder shall cease with respect to such Security or Securities (or the portion thereof being converted) at such time, and the Person or Persons entitled to receive the shares of Common Stock deliverable upon conversion of such Security or Securities shall be treated for all purposes as having become the record holder or holders of such shares of Common Stock at such time, and such conversion shall be at the conversion price in effect at such time; provided, however, that no such surrender on any date when the stock transfer books of the Company shall be closed shall - 78 - 89 be effective to constitute the Person or Persons entitled to receive the shares of Common Stock deliverable upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes immediately prior to the close of business on the next succeeding day on which such stock transfer books are open, and such conversion shall be deemed to have been made at, and shall be made at the conversion rate in effect at, such time on such next succeeding day. All shares of Common Stock delivered upon conversion of Restricted Securities shall bear restrictive legends substantially in the form of the legends required to be set forth on the Restricted Securities pursuant to Section 305(c) and shall be subject to the restrictions on transfer provided in such legends. Neither the Trustee nor any agent maintained for the purpose of such conversion shall have any responsibility for the inclusion or content of any such restrictive legends on such Common Stock; provided, however, that the Trustee or any agent maintained for the purpose of such conversion shall provided, to the Company or to the Company's transfer agent for such Common Stock, prior to or concurrently with a request to the Company to deliver such Common Stock, written notice that the Securities delivered for conversion are Restricted Securities. If shares of Common Stock to be issued upon conversion of a Restricted Security, or Registered Securities to be issued upon conversion of a Restricted Security in part only, are to be registered in a name other than that of the beneficial owner of such Restricted Security, then such Holder must deliver to the conversion agent designated by the Company a Surrender Certificate, dated the date of surrender of such Restricted Security and signed by such beneficial owner, as to compliance with the restrictions on transfer applicable to such Restricted Security. Neither the Trustee nor any conversion agent designated by the Company, Registrar or Transfer Agent shall be required to register in a name other than that of the beneficial owner, shares of Common Stock or Securities issued upon conversion of any such Restricted Security not so accompanied by a properly completed Surrender Certificate. If the last day for the exercise of the conversion right shall not be a Business Day, then such conversion right may be exercised on the next succeeding Business Day. Section 1303. No Adjustments in Respect of Interest or Dividends. Securities surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date shall (except in the case of Securities or portions thereof which have been called for redemption) be accompanied by payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of Securities being surrendered for conversion. Upon a call for redemption by the Company, accrued and unpaid interest to the Redemption Date shall be payable with respect to Securities converted after the redemption notice has been mailed and prior to the Redemption Date. Except as provided in this Section 1303 and subject to the last paragraph of - 79 - 90 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 shares of Common Stock issued upon conversion. Section 1304. Adjustment of Conversion Price. The conversion price, and consequently the number of shares of Common Stock into which a Security is convertible, shall be subject to adjustment from time to time as follows: (a) In case the Company shall (i) pay a dividend on Common Stock or make a distribution on its Common Stock that is paid or made (1) in shares of any class of capital stock of the Company or (2) in rights to purchase any stock or other securities if such rights are not separable from the Common Stock except upon the occurrence of a contingency, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares or (iii) combine its outstanding shares of Common Stock into a smaller number of shares, then in each such case the conversion price in effect immediately prior thereto shall be adjusted retroactively as provided below so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock and other shares and rights to purchase stock or other securities (or, in the event of the redemption of any such shares or rights, any cash, property or securities paid in respect of such redemption) which such Holder would have owned or have been entitled to receive after the happening of any of the events described above had such Security been converted immediately prior to the happening of such event. An adjustment made pursuant to this Subsection (a) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. (b) In case the Company shall issue rights or warrants to all holders of its Common Stock entitling them (for a period expiring within 45 days after the date fixed for determination mentioned below) to subscribe for or purchase shares of Common Stock at a price per share less than the current market price per share (determined as provided in paragraph (d) of this Section) of the Common Stock on the date fixed for the determination of stockholders entitled to receive such rights or warrants, then the conversion price in effect at the opening of business on the day following the date fixed for such determination shall be decreased by multiplying such conversion price by a fraction of which 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, and 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 purchase would purchase at such current market price, such reduction to become effective immediately after the opening of business on the day following the date fixed for such determination; provided, however, in the event that all - 80- 91 the shares of Common Stock offered for subscription or purchase are not delivered upon the exercise of such rights or warrants, upon the expiration of such rights or warrants the conversion price shall be readjusted to the conversion price which would have been in effect had the numerator and the denominator of the foregoing fraction and the resulting adjustment been made based upon the number of shares of Common Stock actually delivered upon the exercise of such rights or warrants rather than upon the number of shares of Common Stock offered for subscription or purchase. 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. (c) In case the Company shall, by dividend or otherwise, distribute to substantially all holders of its Common Stock evidences of its indebtedness, cash (excluding quarterly cash dividends paid or to be paid on a regular basis), other assets or rights or warrants to subscribe for or purchase any securities (excluding those referred to in paragraphs (a) and (b) above), then in each such case, the conversion price shall be adjusted retroactively so that the same shall equal the price determined 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 receive such distribution by a fraction of which the denominator shall be the current market price per share (determined as provided in paragraph (d) of this Section) of the Common Stock on the date fixed for such determination and the numerator shall be such current market price per share of the Common Stock less the amount of cash and the then fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution filed with the Trustee) of the portion of the assets, rights, warrants or evidences of indebtedness so distributed applicable to one share of Common Stock, such adjustment to become effective immediately prior to the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such distribution. (d) For the purpose of any computation under paragraphs (b) and (c) of this Section, the current market price per share of Common Stock on any date shall be deemed to be the average of the daily closing prices for the 30 consecutive trading days commencing with the 45th trading day before the day in question. The closing price for each day shall be 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 composite tape of the principal national securities exchange upon which the Common Stock is listed or on the NASDAQ National Market System (based on the aggregate dollar value of all securities listed or admitted to trading) or, if the Common Stock is not listed or admitted to trading on any national securities exchange or quoted on the NASDAQ National Market System, 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, or, if such prices are not available, the fair market value set by, or in a manner established by, the Board of Directors of the Company in good faith. "Trading day" shall mean a - 81 - 92 day on which the national securities exchange or the NASDAQ National Market System used to determine the closing price is open for the transaction of business or the reporting of trades or, if the closing price is not so determined, a day on which the New York Stock Exchange is open for the transaction of business. (e) No adjustment in the conversion price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that the Company may make any such adjustment at its election; and provided, further, that any adjustments which by reason of this paragraph (e) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article Thirteen shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. (f) Whenever the conversion price is adjusted as provided in any provision of this Article Thirteen: (i) the Company shall compute the adjusted conversion price in accordance with paragraph (d) and shall prepare a certificate signed by the principal financial officer of the Company setting forth the adjusted conversion price and showing in reasonable detail the facts and calculations upon which such adjustment is based, and such certificate shall forthwith be filed with the Trustee and at each office or agency maintained for the purpose of conversion of Securities; and (ii) a notice stating that the conversion price has been adjusted and setting forth the adjusted conversion price shall forthwith be required, and as soon as practicable after it is required, such notice shall be mailed by the Company to all Holders at their last addresses as they shall appear in the Security Register. (g) In the event that at any time, as a result of any adjustment made pursuant to this Article Thirteen, the Holder of any Security thereafter surrendered for conversion shall become entitled to receive any shares of the Company other than shares of Common Stock or to receive any other securities, the number of such other shares or securities so receivable upon conversion of any Security shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions contained in this Article Thirteen with respect to the Common Stock. (h) The Company from time to time may, by Board Resolution delivered to the Trustee, decrease the conversion price by any amount for any period of time if the period is at least 20 days and if the decrease is irrevocable during the period. Whenever the conversion price is so decreased, the Company shall mail to the Holders a notice of the decrease at least 15 days before the date the decreased conversion price takes effect, and such notice shall state the decreased conversion price and the period it will be in effect. - 82 - 93 (i) The Company may make such decreases in the conversion price, in addition to those required or allowed by this Article Thirteen, as shall be determined by it, as evidenced by a Board Resolution delivered to the Trustee, to be advisable in order to avoid or diminish any income tax to holders of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes. (j) In any case in which this Section 1304 provides that an adjustment shall become effective immediately after a record date for an event, the Company may defer until the occurrence of such event (i) issuing to the holder of any Security converted after such record date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 1305. Section 1305. No Fractional Shares. No fractional shares or scrip representing fractional shares 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 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 per share of Common Stock as quoted on the composite tape of the principal national securities exchange upon which the Common Stock is listed or the NASDAQ National Market System 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 NASDAQ National Market System or, if the Common Stock is not listed or admitted to trading on any national securities exchange or quoted on the NASDAQ National Market System, 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, or, if such prices are not available, the fair market value set by, or in a manner established by, the Board of Directors of the Company in good faith, all of the above to be determined as of the close of business on the day of conversion. Section 1306. Reclassification, Consolidation, Merger or Sale of Assets. In case of any reclassification of the Common Stock, 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 of the Company), any sale or other disposition of the assets of the Company substantially as an entirety or any compulsory - 83 - 94 share exchange pursuant to which share exchange the Common Stock is converted into other securities, cash or other property, then the Holder of each Security then outstanding shall have the right thereafter, during the period such Security shall be convertible, pursuant to Section 1301, to convert such Security only into the kind and amount of securities, cash and other property receivable upon such reclassification, consolidation, merger, sale, other disposition or share exchange by a holder of the number of shares of Common Stock of the Company into which such Security might have been converted immediately prior to such reclassification, consolidation, merger, sale, other disposition or share exchange 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, to which such sale or other disposition was made or a party to such share exchange, as the case may be ("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 reclassification, consolidation, merger, sale, other disposition or share exchange (provided that if the kind or amount of securities, cash and other property receivable upon such reclassification, consolidation, merger, sale, other disposition or share exchange is not the same for each share of Common Stock held immediately prior to such reclassification, consolidation, merger, sale, other disposition or share exchange by others than a constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purpose of this Article the kind and amount of securities, cash and other property receivable upon such reclassification, consolidation, merger, sale, other disposition or share exchange by each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). The Company or the Person formed by such consolidation or resulting from such merger or which acquires such assets or which acquires the Company's shares, as the case may be, shall execute and deliver to the Trustee a supplemental indenture to establish such right. Such supplemental indenture shall provide for adjustments which, for events subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article. The above provisions of this Section shall similarly apply to successive reclassifications, consolidations, mergers, sales, other dispositions or share exchanges. Notice of the execution of such a supplemental indenture shall be given by the Company to each Holder by mailing such notice to his last address appearing on the Security Register. Neither the Trustee nor any conversion agent shall be under any responsibility to determine the correctness of any provisions contained in any such supplemental indenture relating either to the kind or amount of shares of stock or securities or cash or property receivable by Holders of Securities upon the conversion of their Securities after any such reclassification, change, consolidation, merger, sale or other disposition or to any such adjustment, but, subject to the provisions of Section 601, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an Opinion of Counsel with respect thereto, which the Company shall cause to be furnished to the Trustee upon request. - 84 - 95 Section 1307. Prior Notice of Certain Events. In case: (a) the Company shall (i) declare any dividend (or any other distribution) on its Common Stock other than (1) a dividend payable in shares of Common Stock or (2) a quarterly cash dividend paid or to be paid on a regular basis or (ii) declare or authorize a redemption or repurchase of in excess of 10% of the then outstanding shares of Common Stock; 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 stock of any class or of any other rights or warrants; or (c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or other disposition of the assets of the Company substantially as an entirety or of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or other property; or (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; then the Company shall cause to be filed with the Trustee and to be mailed to each Holder of Securities at his last address appearing on the Security Register, as promptly as possible but in any event at least 15 days prior to the applicable 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 to be entitled to such dividend, distribution, rights or warrants are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, other disposition, share exchange, 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 or other property deliverable upon such reclassification, consolidation, merger, sale, other disposition, share exchange, dissolution, liquidation or winding up. Section 1308. Shares to be Reserved; Accounting Treatment of Consideration. The Company covenants that it will at all times reserve and keep available out of its authorized but unissued Common Stock, free from preemptive rights solely for the purpose of issue upon conversion of Securities as herein provided, such number of shares of Common Stock as shall then be issuable upon the conversion of all outstanding Securities. The Company - 85 - 96 covenants that all shares of Common Stock which shall be so issuable shall, when issued, be duly and validly issued and fully paid and nonassessable. The Company covenants that, upon conversion of Securities as herein provided, there will be credited to the Common Stock capital account from the consideration for which the shares of Common Stock issuable upon such conversion are issued an amount per share of Common Stock so issued as determined by the Board of Directors, which amount shall not be less than the amount required by law and by the Company's certificate of incorporation, as amended, as in effect on the date of such conversion. For the purposes of this covenant the principal amount of the Securities converted, less any cash paid in respect of fractional share interests upon such conversion, shall be deemed to be the amount of consideration for which the shares of Common Stock issuable upon such conversion are issued. Section 1309. Listing of Shares. The Company covenants that so long as the Common Stock of the Company is listed on any national securities exchange or on the NASDAQ National Market System, the Company will, if permitted by the rules thereof, list and keep listed thereon, upon official notice of issuance, all shares of Common Stock issuable upon conversion of Securities. Section 1310. Taxes and Charges. The issuance of certificates for shares of Common Stock upon the conversion of Securities shall be made without charge to the converting Holder of Securities for such certificates or for any tax in respect of the issuance of such certificates or the securities represented thereby, and such certificates shall be issued in the respective names of, or in such names as may be directed by, the Holders of the Securities converted; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any such certificate in a name other than that of the Holder of the Security converted, and the Company shall not be required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. Section 1311. Trustee and Conversion Agents Not Liable. Neither the Trustee nor any conversion agent shall at any time be under any duty or responsibility to any Holder of Securities to determine whether any facts exist which may require any adjustment of the conversion rate, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. Neither the Trustee nor any conversion agent shall 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 cash or other property which may at any time be issued or delivered upon the conversion of any Security, or makes any representation with - 86 - 97 respect thereto. Neither the Trustee nor any conversion agent shall be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property upon the surrender of any Security for the purpose of conversion, or, subject to Section 601, with any of the covenants of the Company contained in this Article Thirteen. ARTICLE FOURTEEN SUBORDINATION OF SECURITIES Section 1401. Securities Subordinate to Senior Indebtedness. The Companyh covenants and agrees, and each Holder of a Security by his acceptance thereof likewise covenants and agrees that, to the extent and in the manner hereinafter set forth in this Article, 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 1402. Payment Over of Proceeds Upon Dissolution, Etc. Upon any distribution of assets of the Company in the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other winding up of the Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit 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 on account of principal of (or premium, if any) or interest (including any Liquidated Damages) 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. In furtherance of the foregoing, but not by way of limitation thereof, in the event of any case or proceeding described in clause (a) above with the result that the Company is excused from the obligation to pay all or any part of the interest otherwise payable in respect of any Senior Indebtedness during the period subsequent to the commencement of any such case or proceeding, all or such part, as the case - 87 - 98 may be, of such interest shall be payable out of, and to that extent shall diminish and be at the expense of, reorganization dividends or other distributions in respect of the Notes. 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 then have been made known to the Trustee, or, as the case may be, such Holder, 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 shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment the payment of which is subordinated at least to the extent provided in this Article with respect to the Securities to the payment of all Senior Indebtedness which may at the time be outstanding; provided, however, that (i) such Senior Indebtedness is assumed by the new corporation, if any, resulting from any such reorganization or readjustment, and (ii) the rights of the holders of the Senior Indebtedness are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another Person or the liquidation or dissolution of the Company following the conveyance or other disposition 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, 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 the Person which acquires by conveyance or other disposition such properties and assets substantially as an entirety, as the case may be, shall, as a part of such consolidation, merger, conveyance or other disposition, comply with the conditions set forth in Article Eight. Section 1403. 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 or to become due on or in respect of all 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 - 88 - 99 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 (including any Liquidated Damages) 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 Securities prohibited by the foregoing provisions of this Section, and if such facts shall then have been made known to the Trustee or, as the case may be, such Holder, then and in such event such payment shall be paid over and delivered forthwith to the Company for the benefit of the holders of Senior Indebtedness. The provisions of this Section shall not apply to any payment with respect to which Section 1402 would be applicable. Section 1404. No Payment When Senior Indebtedness in Default. (a) In the event and during the continuation of any default in the payment of principal (or premium, if any) or interest on any Senior Indebtedness, or in the payment of any commitment or other fees in respect thereof, or in the event that any event of default with respect to any Senior Indebtedness shall have occurred and be continuing permitting the holders of such Senior Indebtedness (or a trustee on behalf of the holders thereof) to declare such Senior Indebtedness due and payable prior to the date on which it would otherwise have become due and payable, unless and until such event of default shall have been cured or waived or shall have ceased to exist and such acceleration shall have been rescinded or annulled, or (b) in the event any judicial proceeding shall be pending with respect to any such default in payment or event of default; then no 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) shall be made by the Company on account of 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, and if such fact shall then have been made known to the Trustee or, as the case may be, such Holder, then and in such event such payment shall be paid over and delivered forthwith to the Company for the benefit of the holders of Senior Indebtedness. The provisions of this Section shall not apply to any payment with respect to which Section 1402 would be applicable. Section 1405. Acknowledgment of Reliance. Each Holder of Notes by his acceptance thereof acknowledges and agrees that the subordination provisions included herein are, and are intended to be, an inducement and a consideration to each holder of any Senior Indebtedness, whether such Senior Indebtedness was - 89 - 100 created or acquired before or after the issuance of Notes, to acquire and/or continue to hold such Senior Indebtedness, and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and/or continuing to hold such Senior Indebtedness. Section 1406. Subrogation to Rights of Holders of Senior Indebtedness. Subject to the payment in full of all 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 to the rights of the holders of such Senior Indebtedness to receive payments or distributions of cash, property or 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 which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article, and no payments over pursuant to the provisions of this Article to the Company or to the holders of Senior Indebtedness by Holders of the Securities or the Trustee shall, as between 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 Securities. Section 1407. 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 and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, and which, subject to the rights under this Article of the holders of Senior Indebtedness, is intended to rank equally with all other general obligations of the Company, 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 or securities otherwise payable or deliverable to the Trustee or such Holder. Section 1408. 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 - 90 - 101 subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all such purposes. Section 1409. 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 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 1410. 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. Failure to give such notice shall not affect the subordination of the Securities to Senior Indebtedness. 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 a Responsible Officer of 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, at least three Business Days prior to the date upon which by the terms hereof any such 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), the notice with respect to such money provided for in this Section, 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 - 91 - 102 affected by any notice to the contrary which may be received by it within three 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 (or a trustee on behalf of such holder) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee on behalf of any such holder). 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 1411. 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 such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, liquidating trustee, custodian, receiver, 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 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 pursuant thereto or to this Article. Section 1412. 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 any holders of Senior Indebtedness shall be entitled by virtue of this Article or otherwise. Section 1413. 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 - 92 - 103 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 or any predecessor Trustee under or pursuant to Section 607. Section 1414. 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 1413 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. Section 1415. 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 Securities or on account of the purchase or other acquisition of Securities, and (2) the payment, issuance or delivery of cash, 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 stock of any class 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. * * * * This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. - 93 - 104 IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed, all as of the day and year first above written.
