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

Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee or the Company, as the case may be, deems sufficient. (c) The ownership of Securities shall be proved by the Security Register. (d) Any request, demand, authorization, direction, notice, consent, waiver, or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof, in exchange therefor, or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

By: ---------------------- Name: Title: Attest: Section 203 Form of Reverse of Security. This Security is one of a duly authorized issue of Securities of the Company designated as its [6 1/2 to 8]% Convertible Subordinated Debentures Due 2004 (hereinafter referred to as the "Securities"), limited in aggregate principal amount to $28,750,000.00, issued and to be issued under an Indenture, dated as of _______________], 1996 (the "Indenture"), between the Company and _____________________________, as Trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties, and immunities thereunder of the Company, the Trustee, the holders of Senior Indebtedness of the Company, and the Holders of the Securities and the terms upon which the Securities are, and are to be, authenticated and delivered. Subject to, and upon compliance with, the provisions of the Indenture, the Holder of this Security is entitled, at his irrevocable option, at any time and from time to time, on or before the close of business on __________ 15, 2004, or in case this Security or a portion hereof is called for redemption, through optional redemption by the Company, a sinking fund, or otherwise, then in respect of this Security or such portion hereof until and including, but (unless the Company defaults in making the payment due upon redemption) not after, the close of business on the fifth (5th) day preceding the Redemption Date, to convert this Security (or any portion of the principal amount hereof which is $1,000 or an integral multiple thereof), at the principal amount hereof, or of such portion, into fully paid and non-assessable shares (calculated as to each conversion to the nearest 1/100 of a share) of Common Stock of the Company at a conversion price equal to $_________ for each share of Common Stock (or at the current adjusted conversion price if an adjustment has been made as provided in the Indenture) by surrender of this Security, duly endorsed or assigned to the Company or in blank, to the Company at its office or agency in the Borough of Manhattan, The City of New York or at any other office or agency maintained by the Company for such purpose, accompanied by written notice to the Company that the Holder hereof elects to convert this Security, or if less than the entire principal amount hereof is to be converted, the portion hereof to be converted, and, in case such surrender shall be made during the period from the close of business on any Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date (unless this Security or the portion thereof being converted matures prior to such Interest Payment Date or has been called for redemption on a Redemption Date within such period), also accompanied by payment in New York Clearing House 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 this Security then being converted. Subject to the aforesaid requirements for payment and, in the case of a conversion after the Regular Record Date next preceding any Interest Payment Date and on or before such Interest Payment Date, to the right of the Holder of this Security (or any Predecessor Security) of record at such Regular Record Date to receive an installment of interest (with certain exceptions provided in the Indenture), no payment or adjustment is to be made on conversion for interest accrued hereon or for dividends on the Common Stock issued on conversion. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional interest the Company shall pay a cash adjustment as provided in the Indenture. The conversion price is subject to adjustment as provided in the Indenture. In addition, the Indenture provides that in case of certain consolidations or mergers to which the Company is a party or the transfer of substantially all of the assets of the Company, the Indenture shall be amended, without the consent of any Holders of Securities, so that this Security, if then outstanding, will be convertible thereafter, during the period this Security shall be convertible as specified above, only into the kind and amount of securities, cash, and other property receivable upon the consolidation, merger or transfer by a holder of the number of shares of Common Stock into which this Security might have been converted immediately prior to such consolidation, merger, or transfer (assuming such holder of Common Stock failed to exercise any rights of election and received per share the kind and amount received per share by a plurality of non-electing shares). The Securities are redeemable, at the Company's option, as a whole or from time to time in part, upon not less than 45 nor more than 60 days' notice mailed to each Holder of Securities to be redeemed at his address appearing in the Security Register, on any date on or after ________, 2000 and prior to maturity, at a Redemption Price equal to 100% of the principal amount together in the case of any such redemption, with accrued but unpaid interest to the Redemption Date, except that the Securities may not be redeemed prior to Maturity unless for a period of 20 consecutive Trading Days ending on the date immediately preceding the date on which notice of the Redemption Date is given, the Closing Price per share of the Common Stock has equaled or exceeded $_______, subject to adjustment in the case of the same events which would result in an adjustment of the conversion price as provided in Section 1204 of the Indenture with any adjustments to the Closing Price to be effected in the same manner and to the same extent as provided in Section 1204 with respect to adjustments to the conversion price. Interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities (or one or more Predecessor Securities) of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. If there is a Repurchase Event (as defined in the Indenture), the Company will be required to offer to purchase all Securities outstanding on a date 30 days after the Company gives notice of the Repurchase Event at a purchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest to the date of purchase. In the event of redemption, conversion, or repurchase of this Security in part only, a new Security or Securities for the unredeemed, unconverted, or unrepurchased portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. The indebtedness evidenced by this Security is, to the extent provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness of the Company, and this Security is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such purposes. If an Event of Default shall occur and be continuing, the principal amount of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive 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. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal amount of, and interest on, this Security at the times, place, and rate, and in the coin or currency, herein prescribed or to convert this Security as provided in the Indenture. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in the Borough of Manhattan, The City of New York or at any other office or agency maintained by the Company for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. The Securities are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities of a different authorized denomination, as requested by the Holder surrendering the same. No service charge shall be made for any such registration or transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. Prior to due presentment of this Security for registration of transfer, the Company, the Trustee, and any agent for the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee, nor any such agent shall be affected by notice to the contrary. All terms used in this Security which are defined in the Indenture shall have the meanings assigned thereto in the Indenture. Section 204. Form of Trustee's Certificate of Authentication.

The Securities shall be executed on behalf of the Company by its Chairman of the Board of Directors, its Vice Chairman of the Board of Directors, its Chief Executive Officer, its President, or one of its Vice Presidents, under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities; and the Trustee in accordance with such Company Order shall authenticate and make available for delivery such Securities as in this Indenture provided and not otherwise. Each Security shall be dated the date of its authentication. No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature of an authorized officer, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Section 304 Temporary Securities. Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed, or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions, and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. If temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at any office or agency of the Company designated pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute, and the Trustee shall authenticate and make available for delivery in exchange therefor, a like principal amount of definitive Securities of authorized denominations. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities. Section 305 Registration; Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office or in any other office or agency designated pursuant to Section 1002 being herein sometimes referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Securities and transfers of Securities as herein provided. 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 or transferees, one or more new Securities of any authorized denominations and of a like aggregate principal amount. At the option of the Holder, Securities may be exchanged for other Securities of any authorized denominations and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and make available for delivery, the Securities which the Holder making the exchange is entitled to receive. 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 entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) 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. No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Sections 304, 906, 1108, 1202, or 1402 not involving any transfer. The Company shall not be required (i) in the case of a partial redemption of the Securities, to issue, register the transfer of, or exchange, any Security during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities selected for redemption under Section 1104 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of, or exchange, any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. Section 306 Mutilated, Destroyed, Lost, and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute, and the Trustee shall authenticate and deliver in exchange therefor, a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss, or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost, or stolen Security, a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost, or stolen Security has become, or is about to become, due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security upon compliance with the foregoing conditions. Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Every new Security issued pursuant to this Section in lieu of any destroyed, lost, or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost, or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost, or stolen Securities. Section 307 Payment of Interest; Interest Rights Preserved. Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. 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 notwithstanding the fact that such Holder was a Holder on such Regular Record Date, and such Defaulted Interest may be paid by the Company, at its election, as provided in Clause (1) or (2) below: (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days, and not less than 10 days, prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and, if so listed, 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 interest 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 and any Security called for redemption on a Redemption Date within such period), interest the Stated Maturity of which is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Security that is converted, interest whose Stated Maturity is after the date of conversion of such Security shall not be payable. Section 308 Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee, and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of, and (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 canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of, or in exchange for, any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be disposed of in accordance with its customary procedures and a certificate of disposition delivered to the Company, unless by Company Order, the Company directs that canceled certificates be returned to it as directed by a Company Order. Section 310 CUSIP Numbers. The Company in issuing the Securities may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to Holders; provided, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. Section 311 Computation of Interest. Interest on the Securities shall be computed on the basis of a year of twelve 30-day months. Except as provided in the following sentence, the amount of interest payable for any period shorter than a full monthly period for which interest in computed, will be computed on the basis of the actual number of days elapsed in such a 30-day month. 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, or exchange of Securities herein expressly provided for), 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 either: (1) (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 the payment money for which has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid by the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or (B) all such Securities not theretofore delivered to the Trustee for cancellation (i) have become due and payable, or (ii) will become due and payable at their Stated Maturity within one year, or (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for that purpose an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; (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 interest for payment of which 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. Moneys held pursuant to this Section shall not be subject to the claims of the holders of Senior Indebtedness of the Company pursuant to Article Thirteen. Section 403 Reinstatement. If the Trustee or Paying Agent is unable to apply any money in accordance with Section 402 by reason of any order or judgment of any court or governmental authority enjoining, restraining, or otherwise prohibiting such application, then the Company's obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 401 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 402: provided, however, that if the Company makes any payment of principal of, or interest on, any Security following 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. ARTICLE FIVE Remedies Section 501 Events of Default. "Event of Default," wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be occasioned by the provisions of Article Thirteen or be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree, or order of any court or any order, rule, or regulation of any administrative or governmental body): (1) default in the payment of any interest upon any Security when it becomes due and payable, and continuance of such default for a period of 30 days;

or (6) a default under any mortgage, indenture, or instrument under which there may be issued, or by which there may be secured or evidenced, any indebtedness of the Company or any Subsidiary in excess of $1,000,000 either for borrowed money or representing any Senior Indebtedness of the Company, which results in such indebtedness: (i) being declared due and payable prior to the date on which it would otherwise become due and payable after the expiration of any applicable grace period or (ii) becoming due and payable prior to the date on which it would otherwise become due and payable and the holders of such indebtedness take any action to collect such indebtedness; provided, however, that if such default under such mortgage, indenture, or instrument shall be remedied or cured by the Company, or waived by the holders of such indebtedness, then the Event of Default hereunder by reason thereof shall be deemed likewise to have been thereupon remedied, cured, or waived without further action upon the part of either the Trustee or any of the Holders of the Securities; and provided, further, that the Trustee (subject to Sections 601 and 602) shall not have any rights, duties, liabilities, or responsibilities with respect to such default unless and until the Trustee shall have received written notice thereof at the Corporate Trust Office from the Company, the trustee under any such mortgage, indenture, or instrument of indebtedness or the agent of any such holder or holders or the Holder or Holders of any Outstanding Securities and provided, further, that any such default by a Subsidiary shall not constitute an Event of Default unless such Subsidiary or its property also constitutes more than 15% of the Company's Consolidated Total Assets;

provided, however, that notwithstanding anything in this clause to the contrary, any action by or against a Subsidiary of the Company or its property shall not constitute an Eventof Default unless such Subsidiary or its property constitutes 15% or more of the Company's Consolidated Total Assets; or (8) the commencement by the Company or any Subsidiary thereof of a voluntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization, or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or any such Subsidiary to the entry of a decree or order for relief in respect of itself in or an involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization, or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company or any such Subsidiary, or the filing by the Company or any such Subsidiary of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by the Company or any such Subsidiary to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator, or other similar official of the Company or any such Subsidiary or of any substantial part of the property of the Company or any such Subsidiary, or the making by the Company or any such Subsidiary of an assignment for the benefit of creditors, or the admission by the Company or any such Subsidiary in writing of their inability to pay their debts generally as they become due, or the taking of corporate action by the Company or any such Subsidiary in furtherance of any such action; provided, however, that notwithstanding anything in this clause to the contrary, any action by or against a Subsidiary of the Company or its property shall not constitute an Event of Default unless such Subsidiary or its property constitutes 15% or more of the Company's Consolidated Total Assets. The Trustee shall not be charged with knowledge of the identity of any Subsidiary of the Company unless and until the Trustee shall have received written notice thereof at its Corporate Trust Office from the Company or the Holder or Holders of any Outstanding Securities. Section 502 Acceleration of Maturity; Rescission and Annulment. If an Event of Default occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities may declare the principal of all the Securities and any other amounts payable hereunder to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal and all accrued interest shall become immediately due and payable. 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 provided in this Article hereinafter, 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: (i) all overdue interest on all Securities; (ii) the principal of any Securities which have become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Securities; (iii) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate borne by the Securities; and (iv) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements, and advances of the Trustee, its agents, and counsel; and (2) all Events of Default, other than the non-payment of the principal amount 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. 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 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 any Security at Maturity thereof (except for a default referred to in clause (4)), or (3) default is made in the deposit of any sinking fund payment when due hereunder, or (4) default is made in the payment of the Repurchase Price in respect of any Security on the Repurchase Date therefor in accordance with the provisions of Article Fourteen and such default continues for a period of 10 days, 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 interest and, to the extent that payment thereof shall be legally enforceable, interest on any overdue principal and on any overdue interest, 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 of another obligor upon the Securities, wherever situated. If an Event of Default occurs and is continuing, the Trustee may, in its discretion, proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. Section 504 Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property, or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator, or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it 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. No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment, or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 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. Section 506 Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or interest upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all amounts due the Trustee under Section 607; and SECOND: Subject to Article Thirteen, to the payment of the amounts then due and unpaid for principal amount of, 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 interest, respectively. Section 507 Limitation on Suits. No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default; (2) the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses, and liabilities to be incurred in compliance with such request; (4) the Trustee for 60 days after its receipt of such notice, request, and offer of indemnity has failed to institute any such proceeding; and (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities; it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb, or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders. Section 508 Unconditional Right of Holders to Receive Principal and Interest and to Convert. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal amount of, 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) and to convert such Security in accordance with Article Twelve and to institute suit for the enforcement of any such payment and right to convert, and such rights shall not be impaired without the consent of such Holder. Section 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. Section 512 Control by Holders. The Holders of a majority in principal amount of the Outstanding Securities shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee; provided, that: (1) such direction shall not be in conflict with any rule of law or with this Indenture; (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, by a Responsible Officer or Officers of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability. Section 513 Waiver of Past Defaults. Subject to Section 902 hereof, the Holders of not less than a majority in principal amount of the Outstanding Securities may, on behalf of the Holders of all the Securities, waive any past default hereunder and its consequences, except a default: (1) in the payment of the principal amount of, or interest on, any Security (unless such default has been cured and a sum sufficient to pay all matured installments of interest and principal due otherwise than by acceleration has been deposited with the Trustee); 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. Setion 514 Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered, or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may, in its discretion, assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 25% in principal amount of the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the principal amount of, or interest on, any Security on or after the respective Stated Maturities expressed in such Security (or, in the case of redemption or repurchase, on or after the Redemption Date or Repurchase Date) or for the enforcement of the right to convert any Security in accordance with Article Twelve. Section 515 Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay, or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE SIX The Trustee Section 601 Certain Duties and Responsibilities. (a) Except during the continuance of an Event of Default: (1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture. (b) In case an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.

In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion, or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. Section 613 Appointment of Authenticating Agent. The Trustee may, upon receipt of a Company Request, appoint an Authenticating Agent or Agents which shall be authorized to act on behalf of the Trustee to authenticate Securities issued upon exchange, registration of transfer, partial conversion, partial repurchase or partial redemption, or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Company or the Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company or the Trustee, as the case may be. Upon receiving such a notice of resignation or upon such a termination, or in the case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders as their names and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all rights, powers, and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal amount of, or interest on, any Security and remaining unclaimed for two years after such principal or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of any such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; 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 the Borough of Manhattan, City of 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.

If the Company provides for one or more sinking funds for securities or other similar obligations representing indebtedness for money borrowed ranking equal to or junior to the Securities, and such securities have a maturity or weighted average time to maturity which is on or prior to the Stated Maturity of the Securities, the Company will provide a sinking fund for the Securities calculated to retire that amount of Securities equal to the lesser of (i) the same percentage of outstanding Securities prior to maturity as the percentage of the principal amount of such other indebtedness to be retired prior to maturity on the same payment schedule as such other indebtedness or (ii) such amount of Securities necessary to result in the Securities having the same weighted average time to maturity as such securities or other similar indebtedness. Upon the issuance of such securities, the Company will deliver to the Trustee an Officers' Certificate setting forth the sinking fund schedule for the Securities, demonstrating that such schedule has been calculated in accordance with this Section and stating that such schedule complies with the provisions of this Section. Except as set forth herein with respect to the credit against mandatory sinking fund payments and the redemption price, the terms of the sinking fund applicable to the Securities shall, to the extent reasonably administratively acceptable to the Trustee, be the same as those applicable to the relevant indebtedness. The redemption price of the Securities in connection with any sinking fund shall be 100% of the principal amount thereof plus accrued and unpaid interest to the date fixed for redemption.

If the Company wishes to exercise such option, it shall, not less than 60 days prior to each sinking fund payment date for the Securities, deliver to the Trustee (i) an Officers' Certificate specifying the portion of the sinking fund payment which is to be satisfied by surrendering and crediting Securities, stating the basis of such credit, and certifying that the Securities being used as a credit have not previously been so credited and (ii) any Securities to be so surrendered. Not more than 60 days before each sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1104 and cause notice of the redemption thereof to be given in the name of, and at the expense of, the Company in the manner provided in Section 1105. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106, 1107, and 1108. All monies deposited to fund the sinking fund which are not required by the Trustee for redemption of Securities through operation of the sinking fund shall be promptly refunded to the Company.

Section 1104 Selection by Trustee of Securities to be Redeemed. If less than all the Securities are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities not previously called for redemption, by such method 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 the Securities of a denomination larger than $1,000. If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. The Trustee shall promptly notify the Company and the Security Registrar in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, 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.

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, upon Company Request, by the Trustee in the name and at the expense of the Company. Section 1106 Deposit of Redemption Price. On or 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 in trust as provided in Section 1003) an amount of money 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. If any Security called for redemption is converted, any money deposited with the Trustee or with any Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive interest as provided in the last paragraph of Section 307) be paid to the Company upon Company Request or, if then held by the Company, shall be discharged from such trust. Section 1107 Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued 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 the 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 amount shall, until paid, bear interest from the Redemption Date at the rate borne by the Security. Section 1108 Securities Redeemed in Part. Any Security which is to be redeemed only in part shall be surrendered at an office or agency of the Company designated for that purpose pursuant to Section 1002 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to, and in exchange for, the unredeemed portion of the principal of the Security so surrendered. Section 1109 Conversion Arrangements on Call for Redemption. Notwithstanding anything to the contrary contained in this Indenture, in connection with any redemption of Securities, the Company, by an agreement with one or more investment bankers or other purchasers, may arrange for such purchasers to purchase all Securities called for redemption (the "Called Securities") which are either (i) surrendered for redemption or (ii) not duly surrendered for redemption or conversion prior to the close of business on fifth day prior to the Redemption Date, and to convert the same into shares of Common Stock, by the purchasers' depositing with the Trustee (acting as Paying Agent with respect to the deposit of such amount and as conversion agent with respect to the conversion of such Called Securities), in trust for the Holders of the Called Securities, on or prior to the Redemption Date in the manner agreed to by the Company and such purchasers, an amount sufficient to pay the Redemption Price, payable by the Company on redemption of such Called Securities. In connection with any such arrangement for purchase and conversion, the Trustee as Paying Agent shall pay on or after the Redemption Date such amounts so deposited by the purchasers in exchange for Called Securities surrendered for redemption prior to the close of business on the fifth day prior to the Redemption Date and for all Called Securities surrendered after such Redemption Date. Notwithstanding anything to the contrary contained in this Article Eleven, the obligation of the Company to pay the Redemption Price of such Called Securities shall be satisfied and discharged to the extent such amount is so paid by such purchasers, provided, however, that nothing in this Section 1109 shall in any way relieve the Company of the obligations to pay such Redemption Price on all Called Securities to the extent such amount is not so paid by said purchasers. For all purposes of this Indenture, any Called Securities surrendered by the Holders for redemption, and any Called Securities not duly surrendered for redemption or conversion prior to the close of business on the fifth day prior to the Redemption Date, shall be deemed acquired by such purchasers from such Holders and surrendered by such purchasers for conversion and shall in all respects be deemed to have been converted, all as of immediately prior to the close of business on the fifth day prior to the Redemption Date, subject to the deposit by the purchasers of the above amount as aforesaid. Nothing in this Section 1109 shall in any way limit the right of any Holder of a Security to convert his Security pursuant to the terms of this Indenture any time prior to the close of business on the fifth day preceding the Redemption Date. ARTICLE TWELVE Conversion of Securities Section 1201 Conversion Privilege and Conversion Price. Subject to, and upon compliance with, the provisions of this Article, at the option of the Holder thereof, any Security or any portion of the principal amount thereof which is $1,000 or an integral multiple of $1,000 may be converted at the principal amount thereof, or of such portion thereof, into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100 of a share) of Common Stock, at the conversion price, determined as hereinafter provided, in effect at the time of conversion. Such conversion right shall expire at the close of business on _____________, 2004. In case a Security or portion thereof is called for redemption, such conversion right in respect of the Security or portion so called shall expire at the close of business on the fifth day preceding the Redemption Date, unless the Company defaults in making the payment due upon redemption. The price at which shares of Common Stock shall be delivered upon conversion (herein called the "conversion price") shall be initially $ per share of Common Stock. The conversion price shall be adjusted in certain instances as provided in paragraphs (a), (b), (c), (d), (e), and (f) of Section 1204. In case the Company shall, by dividend or otherwise, declare or make a distribution on its Common Stock referred to in paragraph (a) or (d) of Section 1204 which does not give rise to a conversion price adjustment pursuant to paragraphs (a) or (d) of Section 1204, the Holder of each Security, upon the conversion thereof pursuant to this Article subsequent to the close of business on the date fixed for the determination of stockholders entitled to receive such distribution shall be entitled to receive for each share of Common Stock into which such Security is converted, the portion of the evidences of indebtedness, shares of capital stock, cash, and assets so distributed applicable to one share of Common Stock, provided that, at the election of the Company (such election shall be evidenced by a Board Resolution) with respect to all Holders so converting, the Company may, in lieu of distributing to such Holder any portion of such distribution not consisting of cash or securities of the Company, pay such Holder an amount in cash equal to the fair market value thereof (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution). If any conversion of a Security described in the immediately preceding sentence occurs prior to the payment date for a distribution to holders of Common Stock which the Holder of the Security so converted is entitled to receive in accordance with the immediately preceding sentence, the Company may elect (such election to be evidenced by a Board Resolution) to distribute to such Holder a due bill for the evidences of indebtedness, shares of capital stock, cash, or assets to which such Holder is so entitled, provided that such due bill (i) meets any applicable requirements of the principal national securities exchange or other market on which the Common Stock is then traded and (ii) requires payment or delivery of such evidences of indebtedness, shares of capital stock, cash, or assets no later than the date of payment or delivery thereof to holders of Common Stock receiving such distribution. Section 1202 Exercise of Conversion Privilege. In order to exercise the conversion privilege, the Holder of any Security to be converted shall surrender such Security, duly endorsed or assigned to the Company or in blank, at any office or agency maintained by the Company pursuant to Section 1002, accompanied by written notice to the Company (in the form set forth on the reverse of the Securities) at such office or agency that the Holder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted. Securities surrendered for conversion during the period from the close of business on any Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall (except for Securities whose Maturity is prior to such Interest Payment Date and Securities called for redemption on a Redemption Date within such period) 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. Except as provided in the preceding sentence and subject to the fourth paragraph of Section 307, no payment or adjustment shall be made upon any conversion on account of any interest accrued on the Securities surrendered for conversion or on account of any dividends on the Common Stock issued upon conversion. Securities shall be deemed to have been converted immediately prior to the close of business on the last day prior to the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at such time the rights of Holders of such Securities as Holders shall cease, and the Person or Persons entitled to receive the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common Stock at such time. As promptly as practicable on or after the conversion date, the Company shall issue and shall deliver at such office or agency a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any fraction of a share, as provided in Section 1203. In the case of any Security which is converted in part only, upon such conversion the Company shall execute, and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Security or Securities of authorized denominations in aggregate principal amount equal to the unconverted portion of the principal amount of such Security. Section 1203 Fractions of Shares. No 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 which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of any Security or Securities (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the Closing Price per share of the Common Stock at the close of business on the last day prior to the day of conversion (or, if such day is not a Trading Day, on the Trading Day immediately preceding such day). Section 1204 Conversion Price Adjustments. The conversion price shall be subject to adjustment (without duplication) from time to time as follows: (a) In case the Company shall declare a dividend or make a distribution on the outstanding shares of Common Stock in shares of Common Stock or shall declare or make a dividend or other distribution on any other class of capital stock of the Company or any Subsidiary not wholly owned by the Company which dividend or distribution includes Common Stock, the conversion price in effect at the time of the record date for such dividend or distribution shall be reduced by multiplying such conversion price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the record date for such dividend or distribution and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such adjustment to become effective immediately after the record date for such dividend. [CHECK]Any shares of Common Stock issuable in payment of a dividend shall be deemed to have been issued immediately prior to the time of the record date for such dividend for purposes of calculating the number of outstanding shares of Common Stock of the Company under subsections (c) and (d) below. For the purposes of this subsection (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. In the event that any such dividend or distribution is not paid or made, the conversion price then in effect shall be readjusted, effective as of the date when the Board of Directors determines not to pay or make such dividend or distribution, to the conversion price which would be then in effect if such record date had not been fixed. Such adjustments shall be made successively whenever any event specified above shall occur. (b) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the conversion price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the conversion price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. (c) In case the Company shall fix a record date for the issuance of rights or warrants to all holders of its Common Stock entitling them (for a period expiring within 45 days after the record date mentioned below) to subscribe for or purchase shares of Common Stock (or securities convertible into shares of Common Stock) at a price per share (or having an initial conversion price per share) less than the Current Market Price (as defined in subsection (h) below) of a share of Common Stock on such record date, the conversion price shall be adjusted immediately thereafter so that it shall equal the price determined by multiplying the conversion price in effect immediately prior thereto by a fraction, of which the numerator shall be the number of shares of Common Stock outstanding on such record date plus the number of shares of Common Stock which the aggregate offering price of the number of shares of such Common Stock so offered (or the aggregate initial conversion price of the convertible securities so offered) would purchase at the Current Market Price per share, and of which the denominator shall be the sum of the number of shares of Common Stock outstanding on such record date and the number of additional shares of Common Stock offered for subscription or purchase (or into which the convertible securities so offered are initially convertible). For the purposes of this subsection (c), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. Such adjustment shall be made successively whenever such a record date is fixed and shall become effective immediately after such record date. In the event that such rights or warrants are not so issued, the conversion price then in effect shall be readjusted, effective as of the date when the Board of Directors determines not to issue such rights or warrants, to the conversion price which would then be in effect if such record date had not been fixed. (d) In case the Company shall fix a record date for making a distribution by dividend or otherwise to holders of shares of its Common Stock or holders (other than the Company or wholly-owned Subsidiaries) of capital stock of any Subsidiary, (i) of evidences of indebtedness of the Company or any Subsidiary of the Company, (ii) of assets (including shares of any class of capital stock, cash or other securities, but excluding any rights or warrants referred to in subsection (c) or securities referred to in subsection (e), excluding any dividend or distribution referred to in subsection (a) and excluding any dividend or distribution paid exclusively in cash out of retained or current earnings), or (iii) of rights or warrants entitling the holders thereof to receive upon payment of the consideration set forth therein shares of capital stock of the Company (excluding those referred to in subsection (c) above), in each such case the conversion price shall be adjusted so that it shall equal the price determined by multiplying the conversion price in effect immediately prior thereto by a fraction, of which the numerator shall be the number of shares of Common Stock outstanding on such record date multiplied by the Current Market Price per share on such record date, less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a Board Resolution) on the date of the effectiveness of such conversion price adjustment of said shares or evidences of indebtedness or assets or rights or warrants so distributed, and of which the denominator shall be the number of shares of Common Stock outstanding on such record date multiplied by such Current Market Price per share, such reduction to become effective immediately prior to the opening of business on the day following the later of (a) the date fixed for the payment of such distribution and (b) the date 20 days after the notice relating to such distribution is given pursuant to Section 1206(a). If the Board of Directors determines the fair market value of any distribution for purposes of this subsection (d) by reference to the actual or when issued trading market for any securities comprising such distribution, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price per share pursuant to subsection (h) of this Section. (e) In case the Company shall issue or distribute shares of Common Stock, (excluding shares issued (i) in any of the transactions described in subsection (a) above, (ii) upon conversion or exchange of securities (other than the Securities) convertible into, or exchangeable for, Common Stock described in subsection (f) below, (iii) to employees or consultants under the Company's 1996 Stock Option Plan, as now in effect or hereafter amended, if such shares would otherwise be included in this Section 1204(e), (iv) to the Company's employees or consultants under bona fide benefit plans, employment agreements, or consulting agreements adopted by the Company's Board of Directors and approved by its stockholders or granted at an exercise price of at least 100% of the fair market value of the shares on the date of grant whether or not approved by stockholders, if such shares would otherwise be included in this Section 1204(e) (but only to the extent that the aggregate number of shares excluded by this subdivision (iv), and issued after the date of this Indenture, shall not exceed 10% of the Common Stock outstanding at the time of any such issuance), (v) upon exercise of rights or warrants issued to the holders of Common Stock,(vi) to acquire, or in connection with the acquisition of, all or any portion of a business as a going concern, whether such acquisition shall be effected by purchase of assets, exchange of securities, merger, consolidation, or otherwise, (vii) in connection with the entry into a medical practice or other professional practice management agreement by the Company for a term of at least 5 years, (viii) upon exercise of rights or warrants issued in a bona fide public offering pursuant to a firm commitment underwriting, but only if no adjustment is required pursuant to this Section 1204 (without regard to subsection (j) of this Section 1204) with respect to the transaction giving rise to such rights (provided, however, that in the case of any event described in Subsections (v) through (viii) above, the Board of Directors has determined that the consideration received for such shares of Common Stock equals the Current Market Price of such Common Shares on the date of their issuance), or (ix) pursuant to an offering effected at a discount of less than 5% from the Current Market Price per share determined as provided in Section 1204(h) below) for a consideration per share less than the Current Market Price per share on the date the Company fixes the offering price of such additional shares, the conversion price shall be adjusted immediately thereafter so that it shall equal the price determined by multiplying the conversion price in effect immediately prior thereto by a fraction, of which the numerator shall be the sum of the total number of shares of Common Stock outstanding immediately prior to the issuance of such additional shares and the number of shares of Common Stock which the aggregate consideration received (determined as provided in subsection (g) below) for the issuance of such additional shares would purchase at the Current Market Price per share, and of which the denominator shall be the number of shares of Common Stock outstanding immediately after the issuance of such additional shares. For the purposes of this subsection (e), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. Such adjustment shall be made successively whenever such an issuance is made and shall become effective immediately after such issuance. (f) In case the Company shall issue any securities convertible into, or exchangeable for, shares of Common Stock (excluding securities issued in transactions described in subsections (c) and (d) above, or the Securities) for a consideration per share of Common Stock initially deliverable upon conversion or exchange of such securities (determined as provided in subsection (g) below) less than the Current Market Price per share in effect immediately prior to the issuance of such securities, the conversion price shall be adjusted immediately thereafter so that it shall equal the price determined by multiplying the conversion price in effect immediately prior thereto by a fraction, the numerator of which shall be the sum of the number of shares of Common Stock outstanding immediately prior to the issuance of such securities and the number of shares of Common Stock which the aggregate consideration received (determined as provided in subsection (g) below) for such securities would purchase at the Current Market Price per share, and the denominator of which shall be the sum of the number of shares of Common Stock outstanding immediately prior to such issuance and the maximum number of shares of Common Stock of the Company deliverable upon conversion of, or in exchange for, such securities at the initial conversion or exchange price or rate. For the purposes of this subsection (f), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. Such adjustment shall be made successively whenever such an issuance is made and shall become effective immediately after such issuance. Upon the termination of the right to convert or exchange such securities, the conversion price shall forthwith be readjusted to such conversion price as would have obtained had the adjustments made upon the issuance of such convertible or exchangeable securities been made upon the basis of the delivery of only the number of shares of Common Stock actually delivered upon conversion or exchange of such securities and upon the basis of the consideration actually received by the Company (determined as provided in subsection (g) below) for such securities. (g) For purposes of any computation respecting consideration received pursuant to subsections (e) and (f) above, the following shall apply: (i) in the case of the issuance of shares of Common Stock for cash, the consideration shall be the amount of such cash, provided that in no case shall any deductions be made for any commissions, discounts, or other expenses incurred by the Company for any underwriting of the issue or otherwise in connection therewith; (ii) in the case of the issuance of shares of Common Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the fair market value thereof as determined by the Board of Directors (irrespective of the accounting treatment thereof), whose determination shall be conclusive, and described in a Board Resolution; and (iii) in the case of the issuance of securities convertible into, or exchangeable for, shares of Common Stock, the aggregate consideration received therefor shall be deemed to be the sum of the consideration received by the Company for the isuance of such securities and the additional minimum consideration, if any, to be received by the Company upon the conversion or exchange thereof (the consideration in each case to be determined in the same manner as provided in subparagraphs (i) and (ii) of this subsection (g)). (h) For the purpose of any computation under subsections (c), (d), (e), and (f) above, the "Current Market Price" per share at any date shall be deemed to be the average of the daily Closing Prices for 30 consecutive Trading Days commencing 45 Trading Days before such date. (i) In any case in which this Section 1204 shall require 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 shares of 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 a fractional share of Common Stock pursuant to Section 1203; provided, however, that the Company shall deliver to such Holder a due bill or other appropriate instrument evidencing such Holder's right to receive such additional shares of Common Stock, and such cash, upon the occurrence of the event requiring such adjustment. (j) No adjustment in the conversion price need be made unless such adjustment would require an increase or decrease of at least 1% in the conversion price; provided, however, that any such adjustment which is not required to be made by reason of this subsection (j) shall be carried forward and taken into account in any subsequent adjustment. (k) All calculations under this Section 1204 shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. (l) Notwithstanding any other provision of this Section 1204, no adjustment to the conversion price shall reduce the conversion price below the then par value per share of the Common Stock, and any such purported adjustment shall instead reduce the conversion price to such par value. The Company hereby covenants not to take any action (i) to increase the par value per share of the Common Stock other than in connection with one or more reverse stock splits or (ii) that would or does result in any adjustment in the conversion price that, if made without giving effect to the previous sentence, would cause the conversion price to be less than the then par value share of the Common Stock; provided, however, that the covenant in this sentence shall be suspended if within 10 days of determining in good faith that such action would result in such adjustment (but no later than the Business Day following the effectiveness of such adjustment), the Company gives a notice under Section 1103 and effects the redemption referred to in such notice on the Redemption Date referred to herein, but shall be retroactively reinstated if such notice or redemption does not occur. Section 1205 Notice of Adjustments of Conversion Price and Minimum Closing Price. Whenever the conversion price is adjusted as provided in this Section 1204 or the Minimum Closing Price is adjusted as provided in Sections 1101 and 1204 or the Holders become entitled to receive evidences of indebtedness, shares of capital stock, cash, or assets in connection with the conversion of the Securities in accordance with the third paragraph of Section 1201 (an "Entitlement"), the Company shall promptly file with the Trustee and each Conversion Agent (i) an Officers' Certificate in the case of an adjustment pursuant to subsection (a) of this Section 1204, or (ii) both an Officers' Certificate and a certificate of a firm of independent public accountants, in the case of any other adjustment or an Entitlement, which Officers' Certificate and certificate of independent public accountants shall conform to the provisions of Section 102, in each case setting forth the conversion price and Minimum Closing Price after such adjustment or the amount and nature of such Entitlement and setting forth a brief statement of the facts requiring such adjustment or Entitlement and the computation thereof, which Officers' Certificate and certificate of the firm of independent public accountants shall be conclusive evidence of the correctness of any such adjustment or Entitlement, and promptly after such filing the Company shall mail or cause to be mailed a notice of such adjustment or Entitlement to each Securityholder at his last address as the same appears on the Security Register. Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such Officers' Certificate or certificate except to exhibit the same to any Holder of Securities desiring inspection thereof. Section 1206 Notice of Certain Corporate Action. In case: (a) the Company shall declare a dividend (or any other distribution) on the Common Stock payable otherwise than exclusively in cash; or (b) the Company shall authorize the granting to all holders of Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights (excluding rights, warrants, or options issuable in connection with any employee benefit plan); or (c) of any reclassification of Common Stock (other than a subdivision or combination of the outstanding Common Stock), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company shall be required, or of the sale or transfer of all or substantially all of the assets of the Company; or (d) of the voluntary or involuntary dissolution, liquidation, or winding up of the Company; then the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 1002, and shall cause to be mailed to all Holders at their last addresses as they shall appear in the Security Register, at least 20 days (or 10 days in any case specified in clause (a) or (b) above) prior to the applicable record, effectiveness, or expiration date hereinafter specified a notice stating (x) the date on which a record (if any) 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, transfer, dissolution, liquidation, or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash, or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation, or winding up. Section 1207 Company to Reserve Common Stock. The Company shall at all times reserve and keep available, free from preemptive rights, out of the authorized but unissued Common Stock, for the purpose of effecting the conversion of Securities, the full number of shares of Common Stock then deliverable upon the conversion of all outstanding Securities. All shares of Common Stock which shall be so deliverable shall be duly and validly authorized and issued, fully paid, and nonassessable. Section 1208 Taxes on Conversions. The Company will pay any and all taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of any such tax, or has established to the satisfaction of the Company that such tax has been paid. Section 1209 Covenant as to Common Stock. The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and non-assessable and, except as provided in Section 1208, the Company will pay all taxes, liens, and charges with respect to the issue thereof. Section 1210 Cancellation of Converted Securities. All Securities delivered for conversion shall be delivered to the Trustee to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 309. Section 1211 Provisions in Case of Consolidation, Merger, or Sale of Assets. Subject to any applicable right of each Holder of Securities to cause the Company to purchase his Securities upon a Repurchase Event pursuant to the provisions of Article Fourteen of this Indenture, in case of any consolidation of the Company with, or merger of the Company into, any other Person, any merger of another Person into the Company (other than a merger which does not result in any reclassification, conversion, exchange, or cancellation of outstanding shares of Common Stock) or any sale or transfer of all or substantially all of the assets of the Company, the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then outstanding shall have the right thereafter, during the period such Security shall be convertible as specified in Section 1201, to convert such Security only into the kind and amount of securities, cash, and other property receivable, if any, upon such consolidation, merger, sale, or transfer by a holder of the number of shares of Common Stock into which such Security might have been converted immediately prior to such consolidation, merger, sale, or transfer, assuming such holder of Common Stock (i) is not a Person with which the Company consolidated or into which the Company merged or which merged into the Company or to which such sale or transfer was made, as the case may be (a "Constituent Person"), or an Affiliate of a Constituent Person and (ii) failed to exercise his rights of election, if any, as to the kind or amount of securities, cash, and other property receivable upon such consolidation, merger, sale, or transfer (provided that if the kind or amount of securities, cash, and other property receivable upon such consolidation, merger, sale, or transfer is not the same for each share of Common Stock of the Company held immediately prior to such consolidation, merger, sale, or transfer by other than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purpose of this Section the kind and amount of securities, cash, and other property receivable upon such consolidation, merger, sale, or transfer by each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of non-electing shares). Such supplemental indenture shall provide for adjustments which, for events subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article. The above provisions of this Section shall similarly apply to successive consolidations, mergers, sales, or transfers. Section 1212 Company to Cause Registration of Common Stock. The Company covenants that if any shares of Common Stock required to be reserved for purposes of conversion of Securities hereunder require registration with, or approval of, any governmental authority under any Federal or State law, or listing upon any national securities exchange, before such shares may be issued upon conversion, the Company will in good faith and as expeditiously as possible endeavor to cause such shares to be duly registered, approved or listed, as the case may be. Section 1213 Disclaimer by Trustee of Responsibility for Certain Matters. Subject to Section 601, the Trustee shall not at any time be under any duty or responsibility to any Holder of Securities to determine whether any facts exist which may require any adjustment of the conversion price or Minimum Closing Price, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee shall not be accountable with respect to the validity, value, kind, or amount of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Security, and it makes no representation with respect thereto. The Trustee shall not be responsible for any failure of the Company to issue, transfer, or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Security for the purpose of conversion or, subject to Section 601, to comply with any of the covenants of the Company contained in this Article. Each conversion agent other than the Company shall have the same protection under this Section as the Trustee. ARTICLE THIRTEEN Subordination of Securities Section 1301 Agreements to Subordinate by Company. The Company, for itself, its successors, and its assigns, covenants and agrees, and each Holder of Securities, by his acceptance thereof, likewise covenants and agrees, that payment by the Company of the principal amount of, and interest on, each and all of the Securities is hereby expressly subordinated, to the extent and in the manner hereinafter set forth, in right of payment to the prior payment in full of all Senior Indebtedness of the Company. Section 1302 Distribution on Dissolution, Liquidation, and Reorganization; Subrogation. Upon any distribution of assets of the Company upon any dissolution, winding up, liquidation, or reorganization of the Company, whether voluntary or involuntary, in bankruptcy, insolvency, reorganization, or receivership proceedings, or upon an assignment for the benefit of creditors or any other marshaling of the assets and liabilities of the Company or otherwise (subject to the power of a court of competent jurisdiction to make other equitable provision reflecting the rights conferred in this Indenture upon the Senior Indebtedness of the Company and the holders thereof, with respect to the Securities and the holders thereof, by a lawful plan of reorganization under applicable bankruptcy law): (a) the holders of all Senior Indebtedness of the Company shall be entitled to receive payment in full of the principal amount thereof, premium, if any, and the interest due thereon before the Holders of the Securities are entitled to receive any payment upon the principal amount of, or interest on, indebtedness evidenced by the Securities or on account of any other monetary claims, including such monetary claims as may result from rights of repurchase or rescission, under or in respect of the Securities; and (b) any payment or distribution of assets of the Company of any kind or character, whether in cash, property, or securities, to which the Holders of the Securities or the Trustee would be entitled, except for the provisions of this Article Thirteen, shall be paid by the liquidating trustee or agent or other Person making such payment or distribution, whether a trustee in bankruptcy, a receiver, or liquidating trustee or otherwise, directly to the holders of Senior Indebtedness of the Company or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness of the Company may have been issued, ratably according to the aggregate amounts remaining unpaid on account of the principal amount of, premium, if any, and interest on, the Senior Indebtedness of the Company, held or represented by each, to the extent necessary to make payment in full of all Senior Indebtedness of the Company remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness of the Company; and (c) in the event that, notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or character, whether in cash, property, or securities, shall be received by the Holders of the Securities or by the Trustee before all Senior Indebtedness of the Company is paid in full, such payment or distribution shall be paid over to the holders of such Senior Indebtedness of the Company, or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any such Senior Indebtedness of the Company may have been issued, ratably as aforesaid, for application to the payment of all Senior Indebtedness of the Company remaining unpaid until all such Senior Indebtedness of the Company shall have been paid in full, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness of the Company. Subject to the payment in full of all Senior Indebtedness of the Company, the Holders of the Securities shall be subrogated to the rights of the holders of Senior Indebtedness of the Company to receive payments or distributions of cash, property, or securities of the Company applicable to Senior Indebtedness of the Company until the principal amount of, and interest on, the Securities shall be paid in full, and no such payments or distributions to the Holders of the Securities of cash, property, or securities otherwise distributable to the holders of Senior Indebtedness of the Company shall, as between the Company, its creditors other than the holders of Senior Indebtedness of the Company, and the Holders of the Securities, be deemed to be a payment by the Company to, or on account of, the Securities. It is understood that the provisions of this Article Thirteen 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 of the Company, on the other hand. Nothing contained in this Article Thirteen or elsewhere in this Indenture or in the Securities is intended to, or shall, impair, as between the Company, its creditors other than the holders of Senior Indebtedness of the Company, and the Holders of the Securities, the obligations of the Company, which are unconditional and absolute, to pay to the Holders of the Securities the principal amount of, and interest on, the Securities as and when the same shall become due and payable in accordance with their terms, or to affect the relative rights of the Holders of the Securities and the creditors of the Company other than the holders of Senior Indebtedness of the Company, nor shall anything herein or in the Securities prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article Thirteen of the holders of Senior Indebtedness of the Company in respect of cash, property, or securities of the Company received upon the exercise of any such remedy. Upon any payment or distribution of assets of the Company referred to in this Article Thirteen, the Trustee, subject to the provisions of Section 601, shall be entitled to rely upon a certificate of the liquidating trustee or agent or other Person making any distribution to the Trustee for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of Senior Indebtedness of the Company and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon, and all other facts pertinent thereto or to this Article Thirteen. The Trustee, however, shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of the Company. The Trustee shall not be liable to any such holder if it shall pay over or distribute to or on behalf of Holders of the Securities or the Company monies or assets to which any holder of Senior Indebtedness of the Company shall be entitled by virtue of this Article Thirteen. Nothing in this Article Thirteen shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607. If the Trustee or any Holder of Securities does not file a proper claim or proof of debt in the form required in any proceeding referred to above prior to thirty (30) days before the expiration of the time to file such claim in such proceeding, then the holder of any Senior Indebtedness of the Company or any trustee, representative, or agent therefor is hereby authorized, and has the right, to file an appropriate claim or claims for, or on behalf of, such Holders of Securities. Section 1303 No Payment in Event of Default on Senior Indebtedness. No payment by the Company on account of principal of, or interest on, the Securities, and no payment in respect of sinking fund requirements, if any, the Redemption Price, or any Repurchase Price shall be made before amounts then due for principal of, premium of, if any, and interest on, Senior Indebtedness of the Company have been made or duly provided for in money or money's worth if: (i) there is an event of default on or under any Senior Indebtedness with respect to the payment of all or any portion of any Senior Indebtedness; or (ii) there shall exist a default in any covenant with respect to any Senior Indebtedness (other than as specified in clause (i) of this sentence) and, in such event, such default shall not have been cured or waived or shall not have ceased to exist, the Trustee and the Company shall have received written notice from the holder of such Senior Indebtedness or if there is more than one holder of such Senior Indebtedness from the trustee, representative, or agent of the holders of such Senior Indebtedness stating that no payment shall be made with respect to the Securities, and such default would permit the maturity of such Senior Indebtedness (if not already due and payable) to be accelerated, provided that no such default will prevent any payment on, or in respect of, the Securities for more than 120 days unless the maturity of such Senior Indebtedness has been accelerated, except for a payment under Article Eleven and Section 1006 if, at the time of mailing of notice of redemption pursuant to Section 1105 relating to such payment, there is no event of default on or under Senior Indebtedness of the Company known to the Trustee. Section 1304 Payments Permitted. Nothing contained in this Indenture or in any of the Securities shall (a) affect the obligations of the Company to make, or prevent the Company from making, at any time, except as provided in Sections 1302 and 1303, payments of the principal amount of, or interest on, the Securities or (b) prevent the application by the Trustee of any moneys deposited with it hereunder to the payment of, or on account of, the principal amount of, or interest on, the Securities, unless the Trustee shall have received at is Corporate Trust Office written notice of any event prohibiting the making of such payment except as provided in Section 1303 with respect to payments under Article Eleven and Section 1006. Section 1305 Authorization to Trustee to Effect Subordination. Each Holder of Securities by its acceptance thereof authorizes and directs the Trustee in its behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article Thirteen and appoints the Trustee his attorney-in-fact for any and all such purposes. Section 1306 Notices to Trustee. Notwithstanding the provisions of this Article or any provisions of this Indenture, neither the Trustee nor any Paying Agent (other than the Company) shall be charged with the knowledge of the existence of any Senior Indebtedness of the Company or of any event which would prohibit the making of any payment of monies to or by the Trustee or such Paying Agent, unless and until the Trustee or such Paying Agent shall have received (in the case of the Trustee, at its Corporate Trust Office) written notice thereof from the Company or from the holder of any Senior Indebtedness of the Company or from the trustee, representative, or agent for any such holder, together with proof satisfactory to the Trustee for any such holding of Senior Indebtedness of the Company or of the authority of such trustee, representative, or agent; provided, however, that if at least two Business Days prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the payment of either the principal amount of, or interest on, any Security) the Trustee shall not have received with respect to any such monies the notice provided for in this Section 1306, then, anything herein to the contrary notwithstanding, the Trustee shall have the full power and authority to receive such monies and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such two Business Days prior to such date. 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 of the Company (or a trustee, representative, or agent on behalf of such holder) to establish that such a notice has been given by a holder of Senior Indebtedness of the Company or a trustee, representative, or agent 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 of the Company to participate in any payment or distribution pursuant to this Article Thirteen, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness of the Company held by such Person, the extent to which such Person is entitled to participate in such payment or distribution, and any other facts pertinent to the rights of such Person under this Article Thirteen and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. Section 1307 Trustee as Holder of Senior Indebtedness of the Company. The Trustee shall be entitled to all the rights set forth in this Article Thirteen with respect to any Senior Indebtedness of the Company at any time held by it to the same extent as any other holder of Senior Indebtedness of the Company and nothing in Section 311 of the Trust Indenture Act or in this Indenture shall be construed to deprive the Trustee of any of its rights as such holder. Section 1308 Modification of Terms of Senior Indebtedness of the Company. Any renewal or extension of the time of payment of any Senior Indebtedness of the Company or the exercise by the holders of Senior Indebtedness of the Company of any of their rights under any instrument creating or evidencing Senior Indebtedness of the Company, including, without limitation, the waiver of default thereunder, may be made or done all without notice to or assent from the Holders of the Securities or the Trustee. No compromise, alteration, amendment, modification, extension, renewal, or other change of, or waiver, consent, or other action (collectively an "Action") in respect of, any liability or obligation under or in respect of, or of any of the terms, covenants, or conditions of any indenture or other instrument under which any Senior Indebtedness of the Company is outstanding or of such Senior Indebtedness of the Company, whether or not the Action is in accordance with the provisions of any applicable document, shall in any way alter or affect any of the provisions of this Article Thirteen or of the Securities relating to the subordination thereof. Section 1309 Certain Conversions Not 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 Twelve shall not be deemed to constitute a payment or distribution on account of the principal amount of, or interest on, Securities or on account of the purchase or other acquisition of Securities unless (i) such conversion would result in a change of control for purposes of Section 382 of the Internal Revenue Code and the rules and regulations promulgated thereunder, and (ii) such change in control would result in the loss of, or a limitation on, the annual availability of net operating losses to the Company for tax purposes, 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 amount 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 the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than holders of Senior Indebtedness, and the Holders of the Securities, the right, which is absolute and unconditional, of the Holder of any Security, to convert such Security in accordance with Article Thirteen. Section 1310 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 Thirteen 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 1307 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. ARTICLE FOURTEEN Right to Require Repurchase Section 1401 Right to Require Repurchase. In the event that there shall occur a Repurchase Event (as defined in Section 1406), then each Holder shall have the right, at such Holder's option, to require the Company to purchase, and upon the exercise of such right, the Company shall, subject to the provisions of Section 1303, purchase, all or any part of such Holder's Securities on the date (the "Repurchase Date") that is 30 days after the date the Company gives notice of the Repurchase Event as contemplated in Section 1402(a) at a price (the "Repurchase Price") equal to 100% of the principal amount thereof, together with accrued and unpaid interest to the Repurchase Date. Such right to require the repurchase of Securities shall not continue after a discharge of the Company from its obligations with respect to the Securities in accordance with Article Four. Section 1402 Notice; Method of Exercising Repurchase Right. (a) On or before the 15th day after the Repurchase Event, the Company, or, upon Company Request, the Trustee (in the name and at the expense of the Company), shall give notice of the occurrence of the Repurchase Event and of the repurchase right set forth herein arising as a result thereof by first-class mail, postage prepaid, to each Holder of the Securities at such Holder's address appearing in the Security Register. The Company shall at the same time also deliver a copy of such notice of a repurchase right to the Trustee. Each notice of repurchase right shall state: (1) the Repurchase Date; (2) the date by which the repurchase right must be exercised; (3) the Repurchase Price; and (4) 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 the 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 fifth (5th) day prior to the Repurchase Date (i) written notice of Holder's exercise of such right, which notice shall set forth the name of the Holder, the principal amount of the Security or Securities (or portion of a Security) to be repurchased, and a statement that an election to exercise the repurchase right is being made thereby, and (ii) the Security or Securities with respect to which the repurchase right is being exercised, duly endorsed for transfer to the Company. Such written notice shall be irrevocable following the close of business on the fifth (5th) day prior to the Repurchase Date, provided, however, that the Company, in its sole and absolute discretion, may consent to the withdrawal of any Securities after such date and prior to the Repurchase Date. If the Repurchase Date falls between any Regular Record Date and the next succeeding Interest Payment Date, Securities to be repurchased must be accompanied by payment from the Holder of an amount equal to the interest thereon which the registered Holder thereof is to receive on such Interest Payment Date. (c) In the event that a repurchase right shall be exercised in accordance with the terms hereof, the Company shall on the Repurchase Date pay or cause to be paid in cash to the holder thereof the Repurchase Price of the Security or Securities as to which the repurchase right had been exercised. In the event that a repurchase right is exercised with respect to less than the entire principal amount of a surrendered Security, the Company shall execute and deliver to the Trustee, and the Trustee shall authenticate for issuance in the name of the Holder, a new Security or Securities in the aggregate principal amount of the unrepurchased portion of such surrendered Security. Section 1403 Deposit of Repurchased Price. Prior to the Repurchase Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Repurchase Price of the Securities which are to be repurchased on the Repurchase Date. Section 1404 Securities Not Repurchased on Repurchase Date. If any Security surrendered for repurchase shall not be so paid on the Repurchase Date, the principal amount 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. Section 1405 Securities Repurchased in Part. Any Security which is to be repurchased only in part shall be surrendered at any office or agency of the Company designated for that purpose pursuant to Section 1002 (with, if the Company or the Trustee so requires, due endorsement by, or written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of any authorized denomination as requested by such Holder, in aggregate principal amount equal to, and in exchange for, the unrepurchased portion of the principal of the Security so surrendered. Section 1406 Certain Definitions. For purposes of this Article: (a) "Fundamental Change" means the occurrence of any transaction or event in connection with which all or substantially all of the Common Stock shall be exchanged for, converted into, acquired for, or constitute the right to receive consideration (whether by means of an exchange offer, liquidation, tender offer, consolidation, merger, combination, reclassification, recapitalization, or otherwise) which is not all or substantially all common stock which is (or, upon consummation of or immediately following such transaction or event, will be) listed on a national securities exchange or approved for quotation in any Nasdaq Stock Market or any similar system of automated dissemination of quotations of securities prices. A Fundamental Change shall not include any acquisition of Common Stock by any person or group so long as it does not result in termination of such listing or approval for quotation. For purposes of the definition of a "Fundamental Change," (i) "substantially all of the Common Stock" shall mean at least 85% of the Common Stock outstanding immediately prior to the transaction giving rise to a Fundamental Change, and (ii) consideration shall be "substantially all common stock" if at least 80% of the fair value (as determined in good faith by the Board of Directors) of the total consideration is attributable to common stock. (b) A "Repurchase Event" shall have occurred if a Fundamental Change shall have occurred unless (i) the current market price of the Common Stock per share (which, for the purposes of this Article, shall be deemed to be the average of the daily Closing Prices of the Common Stock for the five consecutive Trading Days before the Fundamental Change) is at least equal to the conversion price per share of the Securities in effect immediately preceding the time of such Fundamental Change, or (ii) (A) the consideration, in the transaction or event giving rise to a Fundamental Change, to the holders of Common Stock consists of (w) cash, (x) securities (other than common stock) that are, or immediately upon issuance will be, listed on a national securities exchange or quoted in the Nasdaq National Market System, or (y) common stock that is, or immediately upon issuance will be, listed on a national securities exchange or approved for quotation in any Nasdaq Stock Market or similar system of automated dissemination of quotations of securities prices, or (z) any combination of cash and such securities, including common stock, and (B) the aggregate fair market value of such consideration (which, in the case of such securities, shall be equal to the average of the daily Closing Prices of such securities during the 10 (ten) consecutive Trading Days commencing with the sixth Trading Day following consummation of such transaction or event) is at least 105% of the conversion price of the Securities in effect on the date immediately preceding the closing date of such transaction or event. 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. IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed, and their respective corporate seals to be hereunto affixed and attested, all as of the day and year first above written.
