For all purposes of this Indenture, except as otherwise expressly provided or unless the context otherwise requires: 8 (a) all references in this instrument to designated "Articles," "Sections" and other subdivisions are to designated articles, sections or other subdivisions of this instrument as originally executed. The words "herein," "hereof" and "hereunder" and other words of similar import refer to this Indenture as a whole and not to any particular article, section or other subdivision; (b) the terms defined in this Article have the meaning assigned to them in this Article, and include the plural as well as the singular; (c) all other terms herein which are defined in the Trust Indenture Act of 1939, as amended, either directly or by reference therein, have the meanings assigned to them therein; and (d) all accounting terms not otherwise defined herein have the meanings assigned to them in accordance with generally accepted accounting principles, which, with respect to any computation required of permitted hereunder, shall mean, except as otherwise herein expressly provided, such accounting principles as are generally accepted at the date or time of such computation.

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. 13 20 In case, by reason of the suspension of regular mail service, or by reason of any other cause, it shall be impractical to give such notice by mail as required by this Indenture, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

In case any such mutilated, destroyed, lost or stolen Debenture has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Debenture, pay such Debenture. Upon the issuance of any new Debenture 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 Debenture issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Debentures shall constitute an original, additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Debenture 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 Debentures duly issued hereunder. 19 26 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 Debentures. Section 3.7 Payment of Interest; Interest Rights Preserved. Interest on any Debenture that 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 Debenture (or one or more Predecessor Debentures) is registered at the close of business on the Regular Record Date, which shall be the 15th day of the month preceding any Interest Payment Date whether or not such day is a Business Day. Any interest on any Debenture that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall accrue from such Interest Payment Date at a rate per annum that is equal to one percent (1%) per annum plus the interest rate stated in the Debenture until all unpaid and accrued interest is paid in full (herein called "Defaulted Interest"). The Defaulted Interest shall forthwith cease to be payable to the registered Holder on the relevant Regular Record Date by virtue of having been such Holder; and, except as hereinafter provided, such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Section 3.7(a) or 3.7(b) below: (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose name the Debenture (or their respective Predecessor Debentures) 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 Debenture and the date of the proposed payment (which shall be not less than 30 days from such notice), 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 that shall be not more than 15 nor 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 or her address as it appears in the Debenture Register, not less than 10 days prior to 20 27 such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of proposed payment of such Defaulted Interest and of the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose name the Debentures (or their respective Predecessor Debentures) are registered on such Special Record Date and shall not longer be payable pursuant to the following Section 3.7(b). (b) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debentures may be listed, and upon such notice as may be required by such exchange, if, after notice is given by the Company to the Trustee of the proposed payment pursuant to this Clause, such payment shall be deemed practicable by the Trustee. If any installment of interest which has a Stated Maturity on or prior to the Redemption Date for any Debentures called for redemption at the election of the Company or requested to be redeemed by a deceased Holder's authorized representative pursuant to Article 10 is not paid or duly provided for on or prior to the Redemption Date in accordance with the foregoing provisions of this Section, such interest shall be payable as part of the Redemption Price of such Debentures. Subject to the foregoing provisions of this Section, each Debenture delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Debenture shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Debenture. All payments of interest on the Debentures to the Persons entitled thereto, whether made by the Company, the Trustee or any Paying Agent, as authorized pursuant to this Indenture, shall be made (subject to collection) by check mailed to the address of the Person entitled thereto, as such address shall appear on the Debenture Register, unless the Trustee determines such method of payment to be inappropriate in the circumstances. In the case of any Debenture that is converted after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other than any Debenture whose Maturity is prior to such Interest Payment Date), interest 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 Debenture (or one or more Predecessor Debentures) is registered at the close of 21 28 business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any debenture that is converted, interest after the date of conversion of such Debenture shall not be payable. Section 3.8 Persons Deemed Owners. The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Debenture is registered as the owner of such Debenture for the purpose of receiving payment of principal of, and (subject to Section 3.7) interest on, such Debenture and for all other purposes whatsoever, whether or not such Debenture is 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 3.9 Cancellation. All Debentures surrendered for payment, conversion, redemption, transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and, if not already cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Debentures previously authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Debentures previously authenticated hereunder that the Company has not issued and sold, and all Debentures so delivered shall be promptly cancelled by the Trustee. No Debentures shall be authenticated in lieu of or in exchange for any Debentures cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Debentures held by the Trustee shall be disposed of as directed by a Company Order. Section 3.10 Authentication and Delivery of Original Issue. Forthwith upon the execution and delivery of this Indenture, or from time to time thereafter, Debentures up to the aggregate principal amount of $11,500,000 may be executed by the Company and delivered to the Trustee for authentication, and shall thereupon be authenticated and delivered by the Trustee upon Company Order, without any further action by the Company. Section 3.11 Computation of Interest. Interest on the Debentures shall be computed on the basis of a 360 day year of twelve 30-day months. 22 29 ARTICLE 4 SATISFACTION AND DISCHARGE Section 4.1 Satisfaction and Discharge of Indenture. The Indenture shall cease to be of further effect (except as to any surviving rights of conversion, transfer or exchange of Debentures herein expressly provided for), and the Trustee, on demand of and at the expense of the Company, shall execute the proper instrument acknowledging satisfaction and discharge of this Indenture, when (a) either (1) all Debentures theretofore authenticated and delivered, other than Debentures which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 3.6, have been cancelled by the Trustee or delivered for cancellation to the Trustee; or (2) all such Debentures not theretofore cancelled or delivered to the Trustee for cancellation (A) have become due and payable, or (B) will become due and payable at their Stated Maturity within one year, or (C) 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 Sections 4.1(a)(2)(A), 4.1(a)(2)(B) or 4.1(a)(2)(C) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose an amount sufficient to pay and discharge the entire indebtedness on such Debentures not theretofore cancelled or delivered to the Trustee for cancellation, for principal and any premium and interest to the date of such deposit, in the case of Debentures which have become due and payable, or to the Stated Maturity or Redemption Date, as the case may be; 23 30 (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and (c) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 6.7 and, if money shall have been deposited with the Trustee pursuant to Section 4.1(a)(2), the obligations under Section 4.2 and Section 9.6 shall survive. Section 4.2 Application of Trust Money. Subject to the provisions of the last paragraph of Section 9.6, all money deposited with the Trustee pursuant to Section 4.1 shall be held in trust and applied by it, in accordance with the provisions of the Debentures 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 whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. ARTICLE 5 REMEDIES Section 5.1 Events of Default. "Event of Default," wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): (a) default in the payment of the principal of (or premium, if any, on) any Debenture at its Maturity whether or not such payment is prohibited by the provisions of Article 12 hereof; or 24 31 (b) default in the payment of any interest upon any Debenture when it becomes due and payable, and continuance of such default for a period of 15 days; or (c) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture, other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with, and continuance of such default or breach for a period of 30 days after there has been given, by registered or certified mail, to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Debentures, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or (d) default under any obligations for money borrowed by the Company and its Subsidiaries aggregating $1,000,000 or more in principal amounts outstanding, whether such obligations now exist or shall hereafter be created, which default(s) shall constitute failure to pay any portion of the principal of such obligations when due and payable after the expiration of any applicable grace period(s) with respect thereto or shall have resulted in such obligations becoming or being declared due and payable prior to the date on which it or they would otherwise have become due and payable, without such obligations having been discharged, or such acceleration having been rescinded or annulled; or (e) entry of a decree or order by a court having jurisdiction in the premises adjudging the Company or any Subsidiary insolvent, or approving as properly filed an involuntary petition seeking reorganization, readjustment, arrangement, composition or similar relief for the Company under the federal bankruptcy laws, or any other similar applicable law of any governmental unit, domestic or foreign, and such decree or order shall have continued undischarged or unstayed for a period of 60 days; or a decree or order or other decision of a court or agency of the appointment of a receiver or conservator or liquidator or trustee or assignee in bankruptcy or insolvency of the Company or of a substantial part of its property, or for the involuntary winding down or liquidation of the Company's affairs, shall have been entered and such decree or order shall have remained in force undischarged and unstayed for a period of 60 days; or, under the provisions of any insolvency, bankruptcy or other law for the relief or aid of creditors, any court shall assume custody or control of the Company or of a substantial part of its property, and such custody and control shall not be terminated or stayed within 60 days from the date of assumption of such custody or control; or (f) institution of proceedings by the Company or any Subsidiary to be adjudicated insolvent, or the consent to the filing of an insolvency proceeding against the Company, or the filing of a petition or answer or consent seeking reorganization, 25 32 readjustment, arrangement, composition, appointment of a receiver or conservator or similar relief under the federal insolvency laws, or any other similar applicable law of any governmental unit, domestic or foreign, or the consent to the filing of any such petition or the consent to the appointment of a receiver or conservator or liquidator or trustee or assignee in insolvency of the Company or of a substantial part of the Company's property, or the making of an assignment for the benefit of creditors, or the admission by the Company in writing of its inability to pay its debts generally as they become due, or the voluntarily suspending transaction of its business (other than in connection with a labor dispute), or any corporate action taken by the Company in furtherance of any of the aforesaid purposes. Section 5.2 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 aggregate principal amount of the Debentures Outstanding may declare the principal amount of all the Debentures 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 amount shall become immediately due and payable. At any time after such declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of 50% in aggregate principal amount of the Debentures Outstanding, by written notice to the Company and Trustee, may rescind and annul such declaration and its consequences if: (a) the Company has paid or deposited with the Trustee a sum sufficient to pay (1) all overdue installments of interest on all Debentures, (2) the principal of (and premium, if any, on) any Debentures which have become due (otherwise than by such declaration of acceleration) and interest thereon at the rate borne by the Debentures, (3) to the extent that payment of such interest is lawful, interest upon overdue installments of interest at the rate borne by the Debentures, and (4) 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 26 33 (b) all Events of Default, other than the non-payment of the principal of and premium, if any, and interest on the Debentures that has become due solely by such acceleration, have been cured or waived as provided in Section 5.12. No such rescission shall affect any subsequent default or impair any right consequent thereon. Section 5.3 Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if: (a) default is made in the payment of the principal of (or premium, if any, on) any Debenture at the Maturity thereof, or (b) default is made in the payment of any installment of interest on any Debenture when such interest becomes due and payable and such default continues for a period of 15 days, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Debentures, the whole amount then due and payable on such Debentures for principal, premium, if any, and interest, with interest upon the overdue principal and, to the extent that payment of such interest shall be legally enforceable, upon overdue installments of interest, at the rate borne by the Debentures; 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 amount forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon the Debentures and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Debentures, 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 property remedy. 27 34 Section 5.4 Trustee May File Proofs of Claim. In case of the pendency of any receivership, conservatorship, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or relative to any other obligor upon the Debentures or the property of the Company or of such other obligor or their creditors, irrespective of whether the principal of the Debentures shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, (a) to file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Debentures, to file such other papers or documents and to take such other actions as the Trustee may deem necessary or advisable in order to have the claims of the Trustee, including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and of the Holders allowed in such judicial proceeding, and (b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any 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 the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.7. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Debentures or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors' or other similar committee. Section 5.5 Trustee May Enforce Claims Without Possession of Debentures. All rights of action and claims under this Indenture or the Debentures may be prosecuted and enforced by the Trustee without the possession of any of the Debentures 28 35 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 Debentures in respect of which such judgment has been recovered. Section 5.6 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 (and premium, if any) or interest, upon presentation of the Debentures and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all amounts due the Trustee under Section 6.7; SECOND: In case the principal of the Debentures shall not have become due, to the payment of interest on the Debentures, in the order of the maturity of the installments of such interest, with interest, to the extent that such interest has been collected by the Trustee, upon the overdue installments of interest at the rate borne by the Debentures, such payments to be made ratably to the Persons entitled thereto, without discrimination or preference; THIRD: In case the principal of the Debentures shall have become due, by declaration or otherwise, to the payment of the whole amount then owing and unpaid upon the Debentures for principal (and premium, if any) and interest, with interest on the overdue principal (and premium, if any) and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Debentures; and in case such monies shall be insufficient to pay in full the whole amount so due and unpaid upon the Debentures, then to the payment of such principal (and premium, if any) and interest, without preference or priority of principal (and premium, if any), or of any installment of interest over any other installment of interest, or of any Debenture over any other Debenture, ratably to the aggregate of such principal (and premium, if any) and accrued and unpaid interest; and FOURTH: The remainder, if any, shall be paid to the Company, its successors or assigns, or to whomsoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct. 29 36 Section 5.7 Limitation on Suits. No Holder of any Debenture 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: (a) such Holder has previously given written notice to the Trustee of a continuing Event of Default; (b) the Holders of not less than 25% in aggregate principal amount of the Outstanding Debentures shall have made a written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (c) 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; (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (e) 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 Debentures; it being understood and intended that no one or more Holders of Debentures 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 of Debentures, 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 of Debentures. Section 5.8 Unconditional Right of Holders to Receive Principal, Premium and Interest and to Convert. Notwithstanding any other provision in this Indenture, the Holder of any Debenture shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and, subject to Section 3.7, interest on such Debenture on the respective Stated Maturities expressed in such Debenture (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and the right to convert such Debenture in accordance with Article 30 37 11 and to institute suit for its enforcement, and such rights shall not be impaired without the consent of such Holder. Section 5.9 Rights and Remedies Cumulative. Except as provided in Section 3.6, 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 5.10 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Debenture 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 5.11 Control by Holders. The Holders of a majority in aggregate principal amount of the Outstanding Debentures 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: (a) such direction shall not be in conflict with any rule of law or with this Indenture, (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction, and (c) the Trustee shall not, in its sole discretion, determine that the action so directed would be unduly prejudicial to the Holders not taking part in such direction or shall not have reasonable cause to believe adequate indemnity against risk or liability is not reasonably assured to it. 31 38 The Company may set a record date for purposes of determining the identity of Holders of Outstanding Debentures entitled to vote or consent to any action as authorized or permitted by Section 316(a) of the Trust Indenture Act. Such record date shall be the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders of Debentures furnished to the Trustee pursuant to Section 7.1 of this Indenture prior to such solicitation. Section 5.12 Waiver of Past Defaults. The Holders of not less than a majority in aggregate principal amount of the Debentures Outstanding may, on behalf of the Holders of all the Debentures, waive any past default hereunder and its consequences, except, unless theretofore cured, a default: (a) in the payment of the principal of, premium, if any, or interest on any Debenture (other than any non-payment of the principal of and premium, if any, and interest on the Debentures that has become due solely by acceleration), or (b) in respect of a covenant or provision hereof that under Article 8 cannot be modified or amended without the consent of the Holder of each Outstanding Debenture affected. Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. Section 5.13 Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Debenture by his or her acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Debentures, or to any suit instituted by a Holder for the enforcement of the payment of the principal of, premium, if any, or interest on any Debenture on or after any applicable Stated Maturity thereof (or, in the 32 39 case of redemption, on or after the Redemption Date) or for the enforcement of the right to convert any Debenture in accordance with the provisions of Article 11. Section 5.14 Waiver of Usury, 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 usury, 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 6 THE TRUSTEE Section 6.1 Certain Duties and Responsibilities. (a) Except during the continuance of an Event of Default: (1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (2) in the absence of actual knowledge or 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 are specifically required to be furnished to the Trustee by any provision hereof, 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 individual would exercise or use under the circumstances in the conduct of his or her own affairs. 33 40 (c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or it own willful misconduct, except that: (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; (2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; (3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a majority in principal amount of the Outstanding Debentures relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under the Indenture; and (4) whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. Section 6.2 Notice of Defaults.

(c) A Holder may exercise its rights specified in Section 9.9(a) upon (1) delivery to the Trustee of a written notice (a "Repurchase Notice") at any time prior to the close of business on the Repurchase Date, stating (A) the certificate number of the Debenture that the Holder will deliver to be purchased and (B) the portion of the principal amount of the Debenture that the Holder will deliver to be purchased, which portion must be $1,000 or an integral multiple thereof and (2) delivery, within the time limits specified in the Repurchase Event Notice, of such Debenture to such Paying Agent at such office (together with all necessary endorsements) and a copy of the Repurchase Notice, such delivery being a condition to receipt by the Holder of the Repurchase Price therefor. If a Holder has elected to deliver to the Company for purchase a portion of a Debenture, and if the principal amount of such portion is $1,000 or an integral multiple of $1,000, the Company shall purchase such portion from the Holder thereof pursuant to this Section 9.9. Provisions of this Indenture that apply to the purchase of all of a Debenture also apply to the purchase of a portion of such Debenture. The Trustee shall promptly notify the Company of the receipt by the former of any and all Repurchase Notices and any and all written notices of withdrawal thereof. (d) Upon receipt by any Paying Agent of a Repurchase Notice, the Holder of the Debenture in respect of which such Repurchase Notice was given shall (unless such Repurchase Notice is validly withdrawn pursuant to Section 9.9(i)) thereafter be entitled to receive solely the Repurchase Price with respect to such Debenture. Such Repurchase Price shall be paid to such Holder promptly following the later of the Business Day following the Repurchase Date (provided the conditions in Section 9.9(c) have been satisfied) and the time of delivery of such Debenture to the relevant Paying Agent at the office of such Paying Agent by the Holder thereof in the manner required by Section 9.9(c). 50 57 (e) On or prior to the Repurchase Date, the Company shall deposit with the Trustee an amount of money in same day funds sufficient to pay the Repurchase Price of all the Debentures or portion thereof which are to be purchased on that date. (f) Upon a Repurchase Notice having been given as aforesaid, Debentures validly tendered, not withdrawn and accepted for payment shall, on the Repurchase Date, become due and payable at the Repurchase Price and from and after such date (unless the Company shall default in the payment of the Repurchase Price) such Debentures shall cease to bear interest. Upon surrender of any such Debenture for purchase in accordance with the foregoing provisions, such Debenture shall be paid by the Company at the Repurchase Price; provided, however, that installments of interest whose Stated Maturity is on or prior to the Repurchase Date shall be payable to the Holders of such Debentures, or one or more Predecessor Debentures, registered as such on the relevant Regular Record Dates. If any Debenture tendered for purchase shall not be paid in accordance with the provisions of this Section 9.9 upon surrender thereof, the principal thereof (and premium, if any, thereon) shall, until paid, bear interest from the Repurchase Date at the rate borne by such Debenture. (g) Any Debenture that is to be purchased only in part shall be surrendered to a Paying Agent at the office of such Paying Agent (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 such Holder's attorney duly authorized in writing), and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Debenture, without service charge, one or more new Debentures of any authorized denomination as requested by such Holder in an aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Debenture so surrendered that is not purchased. (h) The Company shall comply with applicable tender offer rules, including Rule 14e-1 under the Exchange Act, in connection with a Repurchase Offer and may modify a Repurchase Offer to so comply. (i) A Repurchase Notice may be withdrawn before or after delivery by the Holder to the Trustee by means of a written notice of withdrawal (by facsimile transmission or letter) received by the Trustee at the office of the Trustee not later than three Business Days prior to the Repurchase Date, specifying, as applicable: (1) the certificate number of the Debenture with respect of which such notice of withdrawal is being submitted; 51 58 (2) the principal amount of the Debenture with respect to which such notice of withdrawal is being submitted; and (3) the principal amount, if any, of the Debenture that remains subject to the original Repurchase Notice and that has been or will be delivered for purchase by the Company. Each Paying Agent will promptly return to the prospective Holders thereof any Debentures with respect to which a Repurchase Notice has been withdrawn in compliance with this Indenture. Section 9.10 Waiver of Certain Covenants. Without limiting the rights of the Holders and the Company with respect to waivers and amendments set forth in Section 5.12 and 8.2 the Company may omit in any particular instance to comply with any covenant or condition set forth in Sections 9.2 through 9.4, if before or after the time for such compliance the Holders of at least a majority in aggregate principal amount of the Debentures at the time Outstanding shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect. ARTICLE 10 REDEMPTION OF DEBENTURES Section 10.1 Right of Redemption by Company. The Company may, at its option, redeem all or any part of the Debentures at any time prior to December 1, 1998 if the Closing Price per share of the Company's Common Stock has equalled or exceeded 140% of the then effective Conversion Price per share of Common Stock for at least 20 Trading Days within 30 consecutive Trading Days ending not more than ten Trading Days prior to the date of a notice of redemption. Such redemption will be in cash and will be at the Redemption Prices set forth in the Debentures together with accrued interest (including any Defaulted Interest) to the Redemption Date. The Debentures are subject to redemption by the Company, at its option, at any time on or after December 1, 1998 at the Redemption Prices set forth 52 59 in the Debentures, together with accrued interest (including any Defaulted Interest) to the Redemption Date. Section 10.2 Election to Redeem; Notice to Trustee. The election of the Company to redeem any Debentures shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company of all or less than all of the Debentures, the Company shall, at least 60 days prior to the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee) notify the Trustee of such Redemption Date and of the principal amount of Debentures to be redeemed. Section 10.3 Selection by Trustee of Debentures to be Redeemed at the Election of the Company. If less than all the Debentures are to be redeemed at the election of the Company, the particular Debentures to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Debentures not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and that may provide for the selection for redemption of portions (equal to $1,000 or any integral multiple thereof) of the principal of Debentures of a denomination larger than $1,000. If any Debenture selected for partial redemption is converted in part before the termination of the conversion right resulting from such selection, the converted portion of such Debenture shall be deemed (so far as may be possible) to be the portion selected for redemption. Debentures that have been converted during a selection of Debentures to be redeemed shall be treated by the Trustee as Outstanding for the purposes of such selection. The Trustee shall promptly notify the Company in writing of the Debentures selected for redemption and in the case of any Debentures selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Debentures shall relate, in the case of any Debenture redeemed or to be redeemed only in part, to the portion of the principal of such Debenture which has been or is to be redeemed. Section 10.4 Notice of Redemption at the Election of the Company. Notice of redemption at the election of the Company shall be given by the Company, or at the Company's request, by the Trustee in the name and at the expense 53 60 of the Company by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Debentures to be redeemed, at his or her address appearing in the Debenture Register. Each notice of redemption shall state: (a) the Redemption Date, (b) the Redemption Price, (c) if less than all Outstanding Debentures are to be redeemed, the identification (and, in the case of partial redemption, the respective principal amounts) of the Debentures to be redeemed, (d) that on the Redemption Date the Redemption Price will become due and payable upon each such Debenture, and that interest thereon shall cease to accrue from and after said date, (e) the Conversion Price, the date on which the right to convert the principal of the Debentures to be redeemed will terminate and the place or places where such Debentures may be surrendered for conversion, (f) the place or places where such Debentures are to be surrendered for payment of the Redemption Price, and (g) the CUSIP numbers of the Debentures to be redeemed. Section 10.5 Deposit of Redemption Price. Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 9.6) 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 Debentures that are to be redeemed on that date. If any Debenture called for redemption is converted pursuant to Article 11, any money deposited with the Trustee or so segregated and held in trust for the redemption of such Debenture shall (subject to the right of the Holder of such Debenture or any Predecessor Debenture to receive interest as provided in the last paragraph of Section 3.7) be paid to the Company on Company Request, or if then held by the Company, shall be discharged from such trust. 54 61 Section 10.6 Debentures Payable on Redemption Date. Notice of redemption at the election of the Company having been given as aforesaid, the Debentures 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, such Debentures shall cease to bear interest. Upon surrender of such Debentures for redemption in accordance with said notice, such Debentures shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date. Installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Debentures, or one or more Predecessor Debentures, registered as such on the relevant Record Dates according to their terms and the provisions of Section 3.7. If any Debenture called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Debenture. Section 10.7 Debentures Redeemed in Part. Any Debenture which is to be redeemed only in part shall be surrendered at a location specified in the notice of redemption 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 or her attorney duly authorized in writing, and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Debenture without service charge, a new Debenture or Debentures, of any authorized denominations as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Debenture so surrendered. ARTICLE 11 CONVERSION OF DEBENTURES Section 11.1 Conversion Privileges and Conversion Price. Subject to and upon compliance with the provisions of this Article, at the option of the Holder thereof, any Debenture or any portion of the principal amount thereof that is $1,000 or an integral multiple of $1,000 may be converted at the principal amount thereof, or of such portion thereof, into fully paid and non-assessable shares (calculated 55 62 as to each conversion to the nearest 1/100 of a share) of Common Stock of the Company, at the Conversion Price, determined as hereinafter provided, in effect at the time of conversion. Such conversion right shall expire at the close of business on November 1, 2002. In case a Debenture or portion thereof is called for redemption or is repurchased upon the occurrence of a Repurchase Event, such conversion right in respect of the Debenture or portion so called shall expire at the close of business on the Redemption Date or the Repurchase Date, unless the Company defaults in making the payment due upon redemption or repurchase. The price at which shares of Common Stock shall be delivered upon conversion (herein called the "Conversion Price") shall be initially [$_______] per share of Common Stock. Effective [____________, 199_,] this Conversion Price shall be adjusted from time to time as provided in this Article 11. Section 11.2 Exercise of Conversion Privilege. In order to exercise the conversion privilege, the Holder of any Debenture to be converted shall surrender such Debenture, duly endorsed or assigned to the Company or in blank at any office or agency of the Company maintained for that purpose pursuant to Section 9.5, accompanied by written notice to the Company at such office or agency that the Holder elects to convert such Debenture or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted. Debentures 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 in the case of Debentures or portions thereof that have been called for redemption, or are to be repurchased, on such Interest Payment Date or on a Redemption Date or a Repurchase Date within the period beginning on such Regular Record Date and ending on such Interest Payment Date) be accompanied by payment to the Company by wire transfer or certified check 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 Debentures being surrendered for conversion. Subject to the provisions of Section 3.7 relating to the payment of Defaulted Interest by the Company, the interest payment with respect to a Debenture called for redemption on a Redemption Date 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 be payable on such Interest Payment Date to the Holder of such Debenture at the close of business on such Regular Record Date notwithstanding the conversion of such Debenture after such Regular Record Date and prior to such Interest Payment Date, and the Holder converting such Debenture need not include a payment of such interest payment amount upon surrender of such Debenture for conversion. Except as provided in the preceding sentence and 56 63 subject to the final paragraph of Section 3.7, no payment or adjustment shall be made upon any conversion on account of any interest accrued on the Debentures surrendered for conversion or on account of any dividends on the Common Stock issued upon conversion. Debentures shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Debentures for conversion in accordance with the foregoing provisions, and at such time the rights of the Holder of such Debentures 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 11.3. In the case of any Debenture that 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 Debenture or Debentures of authorized denominations in aggregate principal amount equal to the unconverted portion of the principal amount of such Debenture. Section 11.3 Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of Debentures. If more than one Debenture shall be surrendered for conversion at one time by the same Holder, the number of full shares that shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Debentures (or, specified portions thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be issuable upon conversion of any Debenture or Debentures (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 on the last Trading Day prior to the date of conversion. Section 11.4 Adjustment of Conversion Price. The Conversion Price shall be adjusted from time to time as follows: (a) In case the Company shall (i) pay a dividend or make a distribution in shares of its Common Stock; (ii) subdivide its outstanding Common Stock into a greater number of shares, or (iii) combine its outstanding Common Stock into a smaller number 57 64 of shares, the Conversion Price in effect immediately prior thereto shall be adjusted so that the Holder of any Debenture thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock of the Company which he would have owned or have been entitled to receive after the happening of any of the events described above had such Debenture been converted immediately prior to the happening of such event. An adjustment made pursuant to this subsection (a) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of subdivision or combination. (b) In case the Company shall issue rights or warrants to all holders of its Common Stock entitling them (for a period expiring within 45 days after the record date mentioned below) to subscribe for or purchase Common Stock at a price per share less than the current market price per share of Common Stock (as defined in subsection (d) below) at the record date for the determination of shareholders entitled to receive such rights and warrants, the Conversion Price in effect immediately prior thereto shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the date of issuance of such rights and warrants by a fraction of which the numerator shall be the number of shares of Common Stock outstanding on the date of the issuance of such rights or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered would purchase at such current market price, and of which the denominator shall be the number of shares of Common Stock outstanding on the date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase. Such adjustment shall be made successively whenever any such rights or warrants are issued, and shall become effective immediately after such record date. In determining whether any rights or warrants entitle the holder to subscribe for or purchase shares of Common Stock at less than such current market price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants, the value of such consideration, if other than cash, to be determined by the Board of Directors. (c) In case the Company shall distribute to all holders of its Common Stock and securities of the Company (other than Common Stock) or evidences of its indebtedness or assets (excluding cash dividends or distributions paid from retained earnings of the Company) or any rights or warrants to subscribe for or purchase any of its securities (excluding those referred to in subsection (b) above, then in each such case the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the date of such distribution by a fraction of which the numerator shall be the current market price per 58 65 share (as defined in subsection (d) below) of the Common Stock on the record date mentioned below less the then fair market value (as determined by the Board of Directors of the Company, whose determination shall be conclusive, and described in a certificate filed with the Trustee) of the capital stock or assets or evidences of indebtedness so distributed or of such rights or warrants applicable to one share of Common Stock and the denominator shall be the current market price per share (as defined in subsection (d) below) of the Common Stock. Such adjustment shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. (d) For the purpose of any computation under subsections (b) and (c) above, the current market price per share of the Common Stock at any date shall be deemed to be the average of the closing prices for the twenty consecutive Trading Days next preceding the day in question. The closing price for each day shall be (i) the last reported sale price of the Common Stock on the National Market of the National Association of Securities Dealers, Inc., Automated Quotation System, or any similar system of automated dissemination of quotations of securities prices then in common use, if so quoted, or (ii) if not quoted as described in clause (i), the mean between the higher bid and low asked quotations for the Common Stock as reported by the National Quotation Bureau Incorporated if at least two securities dealers have inserted both bid and asked quotations for the Common Stock on at least 5 of the 10 preceding days, or (iii) if the Common Stock is listed or admitted for trading on any national securities exchange, the last sale price, or the closing bid price if no sale occurred, of the Common Stock on the principal securities exchange on which the Common Stock is listed. If the Common Stock is quoted on a national securities or central market system, in lieu of a market or quotation system described above, the closing price shall be determined in the manner set forth in clause (ii) of the preceding sentence if bid and asked quotations are reported but actual transactions are not, and in the manner set forth in clause (iii) of the preceding sentence if actual transactions are reported. If none of the conditions set forth above is met, the closing price of the Common Stock on any day or the average of such closing price for any period shall be the fair market value of the Common Stock as determined by a member firm of the New York Stock Exchange, Inc. selected by the Company. (e) No adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this subsection (e) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 11 shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be. Anything in this Section 11.4 to the contrary notwithstanding, the Company shall be entitled to make such 59 66 reductions in the Conversion Price, in addition to those required by this Section 11.4, as it in its discretion shall determine to be advisable in order that any stock dividends, subdivision of shares, distribution of rights to purchase stock or securities, or a distribution of securities convertible into or exchangeable for stock hereafter made by the Company to its shareholders shall not be taxable. (f) In any case in which this Section 11.4 provides that an adjustment shall become effective immediately after a record date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Debenture converted after such record date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such Holder any amount in cash in lieu of any fractional share pursuant to Section 11.3. (g) The Trustee shall not be responsible for any calculation made under this section. Section 11.5 Notice of Adjustments of Conversion Price. Whenever the Conversion Price is adjusted as herein provided: (a) the Company shall compute the adjusted Conversion Price in accordance with Section 11.4 and shall prepare a certificate signed by the Treasurer of the Company setting forth the adjusted Conversion Price and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be delivered to the Trustee and filed at each office or agency maintained for the purpose of conversion of Debentures pursuant to Section 9.5; and (b) a notice setting forth that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall forthwith be prepared by the Company and mailed to all Holders of Debentures at their last addresses as they shall appear in the Debenture Register. Section 11.6 Notice of Certain Corporation Action. In case: (a) the Company shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash out of its retained earnings; or 60 67 (b) the Company shall authorize the granting to the holders of its Common Stock generally of rights or warrants to subscribe for or purchase any shares of Capital Stock of any class or of any other rights; or (c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding shares of Common Stock), or of any consolidation or merger to which the Company is a party and for which approval of any shareholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or (e) the Company or any subsidiary shall commence a tender offer for all or a portion of the Company's outstanding shares of Common Stock (or shall amend any such tender offer); then the Company shall notify the Trustee and cause to be filed at each office or agency maintained for the purpose of conversion of Debentures pursuant to Section 9.5, and shall cause to be mailed to all Holders of Debentures at their last addresses as they shall appear in the Debenture Register, at least 20 days (or 10 days in any case specified in Section 11.6(a) or 11.6(b) above) prior to the applicable record date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purposes of such dividends, distribution, 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, liquidation or winding up is expected to become effective, and the date on 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, or (z) the date on which such tender offer commenced, the date on which such tender offer is scheduled to expire unless extended, the consideration offered and the material terms thereof (or the material terms of any amendment thereto). Section 11.7 Company to Reserve Common Stock. The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Debentures, the full number of shares of Common Stock then issuable upon the conversion of all Outstanding Debentures. 61 68 Section 11.8 Taxes on Conversion. The Company will pay any and all taxes, other than any franchise or income taxes, that may be payable in respect of the issue or delivery of stock certificates representing shares of Common Stock on conversion of Debentures pursuant hereto. The Company shall not, however, be required to pay any tax that 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 Debenture or Debentures 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 11.9 Covenant as to Common Stock. The Company covenants that all shares of Common Stock that may be issued upon conversion of Debentures will upon issue be fully paid and non-assessable and, except as provided in Section 11.8, the Company will pay all taxes, liens and charges with respect to the issue thereof. Section 11.10 Cancellation of Converted Debentures. All Debentures 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 3.9. Section 11.11 Effect of Reclassification, Consolidation, Merger, Share Exchange or Sale. If any of the following event occur, namely (i) any reclassification or change of outstanding shares of Common Stock issuable upon conversion of the Debentures (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (ii) any consolidation or merger of the Company with another corporation shall be effected as a result of which holders of Common Stock issuable upon conversion of the Debentures shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock or (iii) any sale or conveyance of all or substantially all of the properties and assets of the Company to any other corporation, then the Company or such successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture providing that each Debenture shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) receivable upon such reclassification, change, 62 69 consolidation, merger, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Debentures immediately prior to such reclassification, change, consolidation, merger, statutory share exchange, sale or conveyance. Such supplemental indenture shall provide adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder of Debentures, at his address appearing on the Debenture Register. The above provisions of this Section shall similarly apply to successive reclassifications, consolidations, mergers and sales. ARTICLE 12 SUBORDINATION OF DEBENTURES Section 12.1 Agreement to Subordinate. The Company covenants and agrees, and each Holder of Debentures, by his or her acceptance thereof, likewise covenants and agrees, that the Indebtedness represented by the Debentures and the payment of the principal of and premium, if any, and interest on each and all of the Debentures are 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 as provided in this Article 12.

The indebtedness evidenced by this Debenture 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, and this Debenture is issued subject to the provisions of the Indenture with respect thereto. Each Holder of a Debenture, by acceptance hereof, (a) agrees to and shall be bound by such provisions of the Indenture and all other provisions of the Indenture; (b) authorizes and directs the Trustee to take such action on his or her behalf as may be necessary or appropriate to acknowledge or effectuate, as between the Holders and the holders of the Senior Indebtedness, the subordination of this Debenture as provided in the Indenture; and (c) appoints the Trustee his or her attorney-in-fact for any and all such purposes. Each Holder of this Debenture, by accepting the same, agrees that each holder of Senior Indebtedness, whether created or acquired before or after the issuance of the Debentures, shall be deemed conclusively to have relied on such provisions in acquiring and continuing to hold such Senior Indebtedness. The Debentures are subject to redemption prior to December 1, 1998 at the option of the Company at any time upon not less than 30 nor more than 60 days' notice by first class mail, as a whole or in part, only if the Closing Price per share of the Company's Common Stock has equalled or exceeded 140% of the then effective Conversion Price per share of Common Stock for at least 20 Trading Days within 30 consecutive Trading Days ending not more than ten Trading Days prior to the date of a notice of redemption.

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 Debenture or the portion thereof being converted has been called for redemption, or is to be repurchased, on such Interest Payment Date or on a Redemption Date or a Repurchase Date within such period), this Debenture shall also be accompanied by payment in the form of a certified check or other funds acceptable to the Trustee of an amount equal to the interest payable on such Interest Payment Date on the principal amount of this Debenture then being converted.
