(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, all Notes shall be represented by a Note in global form (the "Global Note") registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in the Global Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor. (c) (1) Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.5(c)), the Global Note may not be transferred as a whole or in part except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. (2) The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Global Note. Initially, the Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co. (3) If (i) the Depositary notifies the Company that it is unwilling or unable to continue as, or ceases to be, a clearing agency registered under Section 17A of the Exchange Act and a successor to the Depositary registered as a clearing agency under Section 17A of the Exchange Act is not able to be appointed by the Company within 90 calendar days, or (ii) the Depositary is at any time unwilling or unable to continue as Depositary and a successor to the Depositary is not able to be appointed by the Company within 90 calendar days, or (iii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of Notes in the form of definitive Notes, the Company shall issue notes in denominations of $1,000 or an integral multiple thereof to all beneficial owners of the Global Note in exchange for their beneficial interests therein. If an Event of Default occurs and is continuing, the Company shall, at the request of the Noteholder thereof, exchange all or part of the Global Note for one or more definitive Notes; PROVIDED that the principal amount of each of such definitive Note and such Global Note, after such exchange, shall be $1,000.00 or an integral multiple thereof. Whenever a Global Note is exchanged as a whole for one or more definitive Notes it shall be surrendered by the holder thereof to the Trustee for cancellation. -19- (4) If a Note in definitive form is issued in exchange for any portion of a Global Note after the close of business on any record date at the office or agency where such exchange occurs and before the opening of business at such office or agency on the next succeeding interest payment date, interest will not be payable on such interest payment date in respect of such definitive Note, but will be payable on such interest payment date only with respect to the exchanged portion of the Global Note in accordance with the provisions of this Indenture. (5) Definitive Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.5(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such definitive Notes to the persons in whose names such definitive Notes are so registered. (6) At such time as all interests in the Global Note have been redeemed, converted, canceled, repurchased or transferred, the Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in the Global Note is exchanged for definitive Notes, redeemed, converted, canceled, repurchased or transferred to a transferee who receives definitive Notes therefor or any definitive Note is exchanged or transferred for part of the Global Note, the principal amount of the Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on the Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. SECTION 2.6. MUTILATED, DESTROYED, LOST OR STOLEN NOTES. (a) In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. (b) The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. Upon -20- the issuance of any substituted Note, 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 connected therewith. In case any Note which has matured or is about to mature or has been called for redemption or is about to be converted into Common Stock shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any paying agent or conversion agent of the destruction, loss or theft of such Note and of the ownership thereof. (c) Every substitute Note issued pursuant to the provisions of this Section 2.6 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender. SECTION 2.7. TEMPORARY NOTES. Pending the preparation of definitive Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the definitive Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the definitive Notes. Without unreasonable delay the Company will execute and deliver to the Trustee or such authenticating agent definitive Notes (other than in the case of Notes in global form) and thereupon any or all temporary Notes (other than any the Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 5.2 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of definitive Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as definitive Notes authenticated and delivered hereunder. -21- SECTION 2.8. CANCELLATION OF NOTES PAID, ETC. All Notes surrendered for the purpose of payment, redemption, repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any paying agent or any Note registrar or any conversion agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. Upon written instructions of the Company, the Trustee shall destroy canceled Notes and, after such destruction, shall deliver a certificate of such destruction to the Company. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. ARTICLE 3. REDEMPTION OF NOTES SECTION 3.1. REDEMPTION PRICES. (a) OPTIONAL REDEMPTION. The Company may, at its option, redeem all or from time to time any part of the Notes on any date prior to maturity, upon notice as set forth in Section 3.2, and at the optional redemption prices set forth in the form of Note attached as EXHIBIT A attached hereto, together with accrued interest, if any, to, but excluding, the date fixed for redemption, PROVIDED, HOWEVER, that, other than as provided in Section 3.1(b), no such redemption shall be effected before [____________ ___, 2007]. (b) PROVISIONAL REDEMPTION. The Notes may not be redeemed by the Company, in whole or in part, pursuant to this Section 3.1(b) prior to [____________ ___, 2005]. After such date, the Notes may be redeemed by the Company (a "Provisional Redemption"), in whole or in part, at any time upon notice as set forth in Section 3.2, at a redemption price equal to $1,000 per $1,000 principal amount of Notes to be redeemed plus accrued and unpaid interest, if any, to the date of redemption (the "Provisional Redemption Date") if the closing price of the Common Stock shall have exceeded 150% of the Conversion Price then in effect for at least 20 Trading Days in any consecutive 30-Trading Day period ending on the Trading Day prior to the date of mailing of the notice of redemption pursuant to Section 3.2 (the "Notice Date"). For purposes of this Article, the term "Conversion Price" shall have the meaning given such term in Section 15.4 hereof. SECTION 3.2. NOTICE OF REDEMPTION; SELECTION OF NOTES. (a) In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to Section 3.1, it shall fix a date for redemption, and it, or at its request (which must be received by the Trustee at least ten (10) Business Days prior to the date the Trustee is requested to give notice as described below unless a shorter period is agreed to by the Trustee), the Trustee in the name of and at the expense of the Company, shall mail or cause to be mailed a notice of such redemption at least twenty (20) and not more than sixty (60) days prior to the date fixed -22- for redemption to the holders of Notes so to be redeemed as a whole or in part at their last addresses as the same appear on the Note register (PROVIDED that if the Company shall give such notice, it shall also give such notice, and notice of the Notes to be redeemed, to the Trustee). Such mailing shall be by first class mail. The notice if mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. (b) Each such notice of redemption shall identify the Notes (including CUSIP number(s)) to be redeemed, shall specify the aggregate principal amount of Notes to be redeemed, the date fixed for redemption, the redemption price at which Notes are to be redeemed, the place or places of payment, that payment will be made upon presentation and surrender of such Notes, that interest accrued to, but excluding, the date fixed for redemption will be paid as specified in said notice, and that on and after said date interest thereon or on the portion thereof to be redeemed will cease to accrue. Such notice shall also state the current Conversion Price and the date on which the right to convert such Notes or portions thereof into Common Stock will expire. If fewer than all the Notes are to be redeemed, the notice of redemption shall identify the Notes to be redeemed. In case any Note is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued. (c) On or prior to the redemption date specified in the notice of redemption given as provided in this Section, the Company will deposit with the Trustee or with one or more paying agents (or, if the Company is acting as its own paying agent, set aside, segregate and hold in trust as provided in Section 5.4) an amount of money sufficient to redeem on the redemption date all the Notes (or portions thereof) so called for redemption (other than those theretofore surrendered for conversion into Common Stock) at the appropriate redemption price, together with accrued interest to, but excluding, the date fixed for redemption; PROVIDED that if such payment is made on the redemption date it must be received by the Trustee or paying agent, as the case may be, by 10:00 a.m. New York City time, on such date. If any Note called for redemption is converted pursuant hereto, any money deposited with the Trustee or any paying agent or so segregated and held in trust for the redemption of such Note shall be paid to the Company upon its request, or, if then held by the Company shall be discharged from such trust. (d) If fewer than all the Notes are to be redeemed, the Company will give the Trustee written notice in the form of an Officers' Certificate not fewer than twenty-five (25) days (or such shorter period of time as may be acceptable to the Trustee) prior to the redemption date as to the aggregate principal amount of Notes to be redeemed. If fewer than all the Notes are to be redeemed, the Trustee shall select the Notes or portions thereof to be redeemed (in principal amounts of $1,000 or integral multiples thereof), by lot, or by a method the Trustee considers fair and appropriate (as long as such method is not prohibited by the rules of any United States national securities exchange or of an established automated over-the-counter trading market in the United States on which the -23- Notes are then listed). If any Note selected for partial redemption is converted in part after such selection, the converted portion of such Note shall be deemed (so far as is possible) to be the portion to be selected for redemption. The Notes (or portions thereof) so selected shall be deemed duly selected for redemption for all purposes hereof, notwithstanding that any such Note is converted as a whole or in part before the mailing of the notice of redemption. (e) Upon any redemption of less than all Notes, the Company and the Trustee may (but need not) treat as outstanding any Notes surrendered for conversion during the period of fifteen (15) days next preceding the mailing of a notice of redemption and may (but need not) treat as not outstanding any Note authenticated and delivered during such period in exchange for the unconverted portion of any Note converted in part during such period. SECTION 3.3. PAYMENT OF NOTES CALLED FOR REDEMPTION. (a) If notice of redemption has been given as above provided, the Notes or portion of Notes with respect to which such notice has been given shall, unless converted into Common Stock pursuant to the terms hereof, become due and payable on the date and at the place or places stated in such notice at the applicable redemption price, together with interest accrued to, but excluding, the date fixed for redemption, and on and after said date (unless the Company shall default in the payment of such Notes at the redemption price, together with interest accrued to, but excluding, said date) interest on the Notes or portion of Notes so called for redemption shall cease to accrue and such Notes shall cease after the close of business on the Business Day next preceding the date fixed for redemption to be convertible into Common Stock and, except as provided in Sections 8.5 and 13.4, to be entitled to any benefit or security under this Indenture, and the holders thereof shall have no right in respect of such Notes except the right to receive the redemption price thereof and unpaid interest to, but excluding, the date fixed for redemption. On presentation and surrender of such Notes at a place of payment in said notice specified, the said Notes or the specified portions thereof to be redeemed shall be paid and redeemed by the Company at the applicable redemption price, together with interest accrued thereon to, but excluding, the date fixed for redemption; PROVIDED that, if the applicable redemption date is an interest payment date, the semi-annual payment of interest becoming due on such date shall be payable to the holders of such Notes registered as such on the relevant record date subject to the terms and provisions of Section 2.3 hereof. (b) Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and deliver to the holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented. (c) Notwithstanding the foregoing, the Trustee shall not redeem any Notes or mail any notice of optional redemption during the continuance of a default in payment of interest or premium on the Notes or of any Event of Default of which, in the case of any Event of Default other than under Section 7.1(a), (b), (c) or (e), a Responsible Officer of -24- the Trustee has knowledge. If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal and premium, if any, shall, until paid or duly provided for, bear interest from the date fixed for redemption at the rate borne by the Note and such Note shall remain convertible into Common Stock until the principal and premium, if any, shall have been paid or duly provided for. SECTION 3.4. CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION. In connection with any redemption of Notes, the Company may arrange for the purchase and conversion of any Notes not converted prior to the expiration of such conversion right by an agreement with one or more investment bankers or other purchasers to purchase such Notes by paying to the Trustee in trust for the Noteholders, on or before the date fixed for redemption, an amount not less than the applicable redemption price, together with interest accrued to the date fixed for redemption, of such Notes. Notwithstanding anything to the contrary contained in this Article 3, the obligation of the Company to pay the redemption price of such Notes, together with interest accrued to, but excluding, the date fixed for redemption, shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers. If such an agreement is entered into, a copy of which, certified as true and correct by the Secretary or Assistant Secretary of the Company will be filed with the Trustee prior to the date fixed for redemption, any Notes not duly surrendered for conversion by the holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such holders and (notwithstanding anything to the contrary contained in Article 15) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the date fixed for redemption (and the right to convert any such Notes shall be deemed to have been extended through such time), subject to payment of the above amount as aforesaid. At the direction of the Company, the Trustee shall hold and dispose of any such amount paid to it in the same manner as it would monies deposited with it by the Company for the redemption of Notes. Without the Trustee's prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Notes shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and the Company agrees to indemnify the Trustee from, and hold it harmless against, any and all loss, liability, damage, claim or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Notes between the Company and such purchasers, including the costs and expenses incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture. ARTICLE 4. SUBORDINATION OF NOTES SECTION 4.1. AGREEMENT OF SUBORDINATION. The Company covenants and agrees, and each holder of Notes issued hereunder by his acceptance thereof likewise covenants and agrees, that all Notes shall be issued subject to the provisions of this Article 4; and each person holding any Note, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees to be bound by such provisions. -25- The payment of the principal of, premium, if any, and interest on all Notes (including, but not limited to, the redemption price or repurchase price with respect to the Notes to be redeemed or repurchased, as provided in this Indenture) issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated to the prior payment in full, in cash or in such other form of payment as may be acceptable to the holders of Senior Indebtedness, of all Senior Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred or created. No provision of this Article 4 shall prevent the occurrence of any default or Event of Default hereunder. SECTION 4.2. PAYMENTS TO NOTEHOLDERS. No payment (including pursuant to any redemption or repurchase of Notes) shall be made with respect to the principal of, or premium, if any, or interest on the Notes, except payments and distributions made by the Trustee as permitted by Section 4.6, if: (a) a default in the payment of principal, premium, if any, or interest or other payment due on Designated Senior Indebtedness occurs and is continuing beyond any applicable period of grace; or (b) any other default occurs and is continuing with respect to Designated Senior Indebtedness that then permits holders of the Designated Senior Indebtedness as to which such default related to accelerate its maturity and the Trustee and the Company receive a notice of such default (a "Payment Blockage Notice") from a representative of Designated Senior Indebtedness or a holder of Designated Senior Indebtedness or the Company. The Company may and shall resume payments on the Notes (1) in the case of a payment default, on the date upon which such default is cured or waived or ceases to exist, and (2) in the case of a nonpayment default with respect to Designated Senior Indebtedness, on the earlier of the date on which the nonpayment default is cured or waived or ceases to exist or 179 days after the date on which the applicable Payment Blockage Notice is received. No new period of payment blockage may be commenced pursuant to a Payment Blockage Notice unless (A) at least 365 days shall have elapsed since the first day of effectiveness of the immediately prior Payment Blockage Notice and (B) all scheduled payments of principal, premium, if any, and interest on the Notes that have come due have been paid in full in cash, or in such other form of payment as may be acceptable to the holders of the Notes. No default (whether or not such event of default is on the same issue of Designated Senior Indebtedness) that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice. In addition, in the event of any acceleration of the Notes because of an Event of Default, no payment or distribution (including with respect to any redemption or repurchase of the Notes) shall be made to the Trustee or any holder of Notes with respect to the principal of, premium, if any, or interest on the Notes, except payments and distributions made by the Trustee as permitted by Section 4.6, until all Senior Indebtedness has been paid in full in cash or other payment satisfactory to the holders of Senior Indebtedness or such acceleration is rescinded in accordance -26- with the terms of this Indenture. If payment of the Notes is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Indebtedness of the acceleration. Notwithstanding the foregoing, in the event that the Trustee or any holder of Notes receives any payment or distribution of assets of the Company of any kind in contravention of any term of this Indenture, whether in cash, property or securities, including, without limitation, by way of setoff or otherwise, before all Senior Indebtedness is paid in full, in cash or such other form of payment as may be acceptable to the holders of Senior Indebtedness, then such payment or distribution shall be held by the recipient or recipients in trust for the benefit of, and shall immediately be paid over or delivered to, the holders of Senior Indebtedness or their respective representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to make payment in full, in cash or such other form of payment as may be acceptable to the holders of Senior Indebtedness, of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution, or provision therefor, to or for the holders of such Senior Indebtedness. Nothing in this Section 4.2 shall apply to claims of, or payments to, the Trustee pursuant to Section 8.6. This Section 4.2 shall be subject to the further provisions of Section 4.6. SECTION 4.3. BANKRUPTCY AND DISSOLUTION, ETC. Upon any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution, winding-up, liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, all amounts due or to become due upon all Senior Indebtedness shall first be paid in full, in cash or in such other form of payment as may be acceptable to the holders of Senior Indebtedness, before any payment is made on account of the principal or premium, if any, and interest on the Notes (except payments made pursuant to Article 13 from monies deposited with the Trustee pursuant thereto prior to the happening of such dissolution, winding-up, liquidation or reorganization or bankruptcy, insolvency, receivership or other such proceedings); and upon any such dissolution, winding-up, liquidation or reorganization or bankruptcy, insolvency, receivership or other such proceedings, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the holders of the Notes or the Trustee under this Indenture would be entitled, except for the provision of this Article 4, shall (except as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, or by the holders of the Notes or by the Trustee under this Indenture if received by them or it, directly to the holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, or as otherwise required by law or a court order) or their respective representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full in cash or in such other form of payment as may be acceptable to the holders of Senior Indebtedness after giving effect to any concurrent payment or distribution to or for the holders of -27- Senior Indebtedness, before any payment or distribution is made to the holders of the Notes or to the Trustee under this Indenture. Notwithstanding the foregoing, in the event that the Trustee or any holder of Notes receives any payment or distribution of assets of the Company of any kind in contravention of any term of this Indenture, whether in cash, property or securities, including, without limitation, by way of setoff or otherwise, before all Senior Indebtedness is paid in full, in cash or such other form of payment as may be acceptable to the holders of Senior Indebtedness, then such payment or distribution shall be held by the recipient or recipients in trust for the benefit of, and shall immediately be paid over or delivered to, the holders of Senior Indebtedness or their respective representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to make payment in full, in cash or such other form of payment as may be acceptable to the holders of Senior Indebtedness, of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution, or provision therefor, to or for the holders of such Senior Indebtedness. For purposes of Section 4.2 hereof and this Section 4.3, the words "cash, property or securities" shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated (at least to the extent provided in this Article 4 with respect to the Notes) to the payment of all Senior Indebtedness which may at the time be outstanding; PROVIDED that (i) the Senior Indebtedness is assumed by the new corporation, if any, resulting from such reorganization or adjustment, and (ii) the rights of the holders of Senior Indebtedness (other than leases which are not assumed by the Company or by the new corporation, as the case may be) are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article 12 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 4.3 if such other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article 12. Nothing in this Section 4.3 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 8.6. This Section 4.3 shall be subject to the further provisions of Section 4.6. SECTION 4.4. SUBROGATION OF NOTES. Subject to the payment in full in cash or in such other form of payment as may be acceptable to the holders of Senior Indebtedness of all Senior Indebtedness, the rights of the holders of the Notes shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article 4 (equally and ratably with the holders of all indebtedness of the Company which by its express terms is subordinated to other indebtedness of the Company to substantially the same extent as the Notes are subordinated and is entitled to like rights of subrogation) to the rights of the holders of Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company applicable to the Senior Indebtedness -28- until the principal of, and premium, if any, and interest on the Notes shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the holders of the Notes or the Trustee would be entitled except for the provisions of this Article 4, and no payment over pursuant to the provisions of this Article 4, to or for the benefit of the holders of Senior Indebtedness by holders of the Notes or the Trustee, shall, as between the Company, its creditors other than holders of Senior Indebtedness, and the holders of the Notes, be deemed to be a payment by the Company to or on account of the Senior Indebtedness; and no payments or distributions of cash, property or securities to or for the benefit of the holders of the Notes pursuant to the subrogation provisions of this Article 4, which would otherwise have been paid to the holders of Senior Indebtedness shall be deemed to be a payment by the Company to or for the account of the Notes. It is understood that the provisions of this Article 4 are and are intended solely for the purposes of defining the relative rights of the holders of the Notes, on the one hand, and the holders of the Senior Indebtedness, on the other hand. Nothing contained in this Article 4 or elsewhere in this Indenture or in the Notes is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Indebtedness, and the holders of the Notes, the obligation of the Company, which is absolute and unconditional, to pay to the holders of the Notes the principal of, and premium, if any, and interest on the Notes as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the holders of the Notes and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the holder of any Note from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 4 of the holders of Senior Indebtedness 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 4, the Trustee, subject to the provisions of Section 8.1, and the holders of the Notes shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, delivered to the Trustee or to the holders of the Notes, for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 4. SECTION 4.5. AUTHORIZATION BY NOTEHOLDERS. Each holder of a Note by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article 4 and appoints the Trustee his attorney-in-fact for any and all such purposes. SECTION 4.6. NOTICE TO TRUSTEE. The Company shall give written notice to the Trustee of the issuance of any Designated Senior Indebtedness. In addition, the Company shall give prompt written notice in the form of an Officers' Certificate to a Responsible Officer of the Trustee and to any paying agent of any fact known to the Company which would prohibit the -29- making of any payment of monies to or by the Trustee or any paying agent in respect of the Notes pursuant to the provisions of this Article 4. Notwithstanding the provisions of this Article 4 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any Senior Indebtedness or of any default or event of default with respect to any Senior Indebtedness or of any other facts which would prohibit the making of any payment of monies to or by the Trustee in respect of the Notes pursuant to the provisions of this Article 4, unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the Corporate Trust Office from the Company (in the form of an Officers' Certificate) or a holder or holders of Senior Indebtedness or from any trustee thereof who shall have been certified by the Company or otherwise established to the reasonable satisfaction of the Trustee to be such holder or trustee; and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 8.1, shall be entitled in all respects to assume that no such facts exist; PROVIDED that if on a date at least two (2) Business Days prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the payment of the principal of, or premium, if any, or interest on any Note), the Trustee shall not have received with respect to such monies the notice provided for in this Section 4.6, then, anything herein contained to the contrary notwithstanding, the Trustee shall have 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 prior date. Notwithstanding anything to the contrary hereinbefore set forth, nothing shall prevent (a) any payment by the Company or the Trustee to the Noteholders of amounts in connection with a redemption of Notes if (i) notice of such redemption has been given to the Noteholders pursuant to Article 3 prior to the receipt by the Trustee of written notice as aforesaid, and (ii) such notice of redemption is given not earlier than sixty (60) days before the redemption date, (b) any payment by the Company or the Trustee to the Noteholders of amounts in connection with a repurchase of Notes if (i) notice of such repurchase has been given pursuant to Article 16 prior to the receipt by the Trustee of written notice as aforesaid, and (ii) such notice of repurchase is given not earlier than forty (40) days before the repurchase date, or (c) any payment by the Trustee to the Noteholders of monies deposited with it pursuant to Section 13.1. The Trustee, subject to the provisions of Section 8.1, shall be entitled to rely on the delivery to it of a written notice by a person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that such notice has been given by a holder of Senior Indebtedness or a trustee on behalf of any such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article 4, the Trustee may request such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such person, the extent to which such person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such person under this Article 4, 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 4.7. TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS. The Trustee and any agent of the Company or the Trustee in its individual capacity shall be entitled -30- to all the rights set forth in this Article 4 in respect of any Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in Section 8.13 or elsewhere in this Indenture shall deprive the Trustee or any such agent of any of its rights as such holder. Nothing in this Article 4 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 8.6. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article 4, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and, subject to the provisions of Section 4.2 and Section 8.1, the Trustee shall not be liable to any holder of Senior Indebtedness if it shall pay over or deliver to holders of Notes, the Company or any other person money or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article 4 or otherwise. SECTION 4.8. NO IMPAIRMENT OF SUBORDINATION. No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with. SECTION 4.9. CERTAIN CONVERSIONS DEEMED PAYMENT. For the purposes of this Article 4 only, (1) the issuance and delivery of junior securities upon conversion of Notes in accordance with Article 15 shall not be deemed to constitute a payment or distribution on account of the principal of (or premium, if any) or interest on Notes or on account of the purchase or other acquisition of Notes, and (2) the payment, issuance or delivery of cash, property or securities (other than junior securities) upon conversion of a Note shall be deemed to constitute payment on account of the principal of such Note. For the purposes of this Section, the term "junior securities" means (a) shares of any stock of any class of the Company and (b) securities of the Company which are subordinated in right of payment to all Senior Indebtedness which may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Notes are so subordinated as provided in this Article. Nothing contained in this Article or elsewhere in this Indenture or in the Notes is intended to or shall impair, as among the Company, its creditors other than holders of Senior Indebtedness and the holders of the Notes, the right, which is absolute and unconditional, of the holder of any Note to convert such Note in accordance with Article 15. SECTION 4.10. ARTICLE APPLICABLE TO PAYING AGENTS. If at any time any paying agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term Trustee as used in this Article 4 shall (unless the context shall otherwise require) be construed as extending to and including such paying agent within its meaning as fully for all intents and purposes as if such paying agent were named in this Article in addition to or in place of the Trustee; PROVIDED, HOWEVER, that the first sentence of Section 4.5 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as paying agent. -31- ARTICLE 5. PARTICULAR COVENANTS OF THE COMPANY SECTION 5.1. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST. The Company covenants and agrees that it will duly and punctually pay or cause to be paid the principal of and premium, if any, and interest on each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes. Each installment of interest on the Notes due on any semi-annual interest payment date may be paid by mailing checks for the interest payable to or upon the written order of the holders of Notes entitled thereto as they shall appear on the registry books of the Company, PROVIDED that, with respect to any holder of Notes with an aggregate principal amount equal to or in excess of $2,000,000, at the request of such holder in writing to the Company, interest on such holder's Notes shall be paid by wire transfer in immediately available funds in accordance with the wire transfer instructions supplied by such holder from time to time to the Trustee and paying agent (if different from Trustee) at least two days prior to the applicable record date; PROVIDED, FURTHER that any payment to the Depositary or its nominee shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. SECTION 5.2. MAINTENANCE OF OFFICE OR AGENCY. The Company will maintain in the Borough of Manhattan, The City of New York, an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or for conversion, redemption or repurchase and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency not designated or appointed by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency of the Trustee in the Borough of Manhattan, The City of New York. The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; PROVIDED that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The Company hereby initially designates the Trustee as paying agent, Note registrar, Custodian and conversion agent and the Corporate Trust Office and the office or agency of the Trustee in the Borough of Manhattan, The City of New York (which initially shall be the office of the Trustee located at 101 Barclay Street, 8W, New York, New York 10286) as one such office or agency of the Company for each of the aforesaid purposes. -32- So long as the Trustee is the Note registrar, the Trustee agrees to mail, or cause to be mailed, the notices set forth in Section 8.10(a) and the third paragraph of Section 8.11. SECTION 5.3. APPOINTMENTS TO FILL VACANCIES IN TRUSTEE'S OFFICE.

The Company shall, on or before each due date of the principal of, premium, if any, or interest on the Notes, deposit with the paying agent a sum sufficient to pay such principal, premium, if any, or interest, and (unless such paying agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action, provided that if such deposit is made on the due date, such deposit must be received by the paying agent by 10:00 a.m., New York City time, on such date. (b) If the Company shall act as its own paying agent, it will, on or before each due date of the principal of, premium, if any, or interest on the Notes, set aside, segregate and hold in trust for the benefit of the holders of the Notes a sum sufficient to pay such principal, premium, if any, or interest so becoming due and will notify the Trustee of any failure to take such action and of any failure by the Company (or any other obligor under the Notes) to make any payment of the principal of, premium, if any, or interest on the Notes when the same shall become due and payable. (c) Anything in this Section 5.4 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any paying agent hereunder as required by this Section 5.4, such -33- sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company or any paying agent to the Trustee, the Company or such paying agent shall be released from all further liability with respect to such sums.

Subject to Article 12, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. SECTION 5.6. STAY, EXTENSION AND USURY LAWS.

SECTION 5.7. COMPLIANCE CERTIFICATE. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2004) an Officers' Certificate one of the signers of which shall be the chief executive, chief financial, or chief accounting officer, stating whether or not to the best of their knowledge the signers know of any default or Event of Default that occurred during such period. If they do, such Officers' Certificate shall describe the default or Event of Default and its status. SECTION 5.8. FURTHER INSTRUMENTS AND ACTS. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. SECTION 5.9. PAYMENT OF TAXES AND OTHER CLAIMS.

or (h) default on the part of the Company or any Significant Subsidiary with respect to any Indebtedness of, or guaranteed or assumed by, the Company or any Significant Subsidiary, which default results in the acceleration of Indebtedness in a principal amount then outstanding in excess of U.S. $5,000,000, and such Indebtedness shall not have been discharged or such acceleration shall not have been rescinded or annulled for a period of thirty (30) days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the holders of not less than 25% in aggregate principal amount of the Notes then outstanding, a written notice specifying such default and requiring the Company to cause such Indebtedness to be discharged or cause such default to be cured or waived or such acceleration to be rescinded or annulled and stating that such notice is a "Notice of Default" hereunder; or (i) the Company or any Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to itself or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or (j) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation, reorganization or other relief with respect to it or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of ninety (90) consecutive days; then, and in each and every such case (other than an Event of Default specified in Section 7.1(i) or (j) with respect to the Company), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes then outstanding hereunder determined in accordance with Section 9.4, by notice in writing to the Company (and to the Trustee if given by Noteholders), may declare the principal of and premium, if any, on all the Notes and the interest accrued thereon to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 7.1(i) or (j) occurs and is continuing with respect to the Company, the principal of all the Notes and the interest accrued thereon shall be immediately due and payable. This provision, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum -42- sufficient to pay all matured installments of interest upon all Notes and the principal of and premium, if any, on any and all Notes which shall have become due otherwise than by acceleration (with interest on overdue installments of interest (to the extent that payment of such interest is enforceable under applicable law) and on such principal and premium, if any, at the rate borne by the Notes, to the date of such payment or deposit) and amounts due to the Trustee pursuant to Section 8.6, and if any and all defaults under this Indenture, other than the nonpayment of principal of and premium, if any, and accrued interest on Notes which shall have become due by acceleration, shall have been cured or waived pursuant to Section 7.7, then and in every such case the holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all defaults or Events of Default and rescind and annul such declaration and its consequences; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or Event of Default, or shall impair any right consequent thereon. The Company shall notify the Responsible Officer of the Trustee, promptly upon becoming aware thereof, of any default or Event of Default and shall deliver to the Trustee a statement specifying such default or Event of Default and the action the Company has taken, is taking or proposes to take with respect thereto. In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the holders of Notes, and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the holders of Notes, and the Trustee shall continue as though no such proceeding had been instituted. SECTION 7.2. PAYMENTS OF NOTES ON DEFAULT; SUIT THEREFOR. The Company covenants that (a) in case default shall be made in the payment by the Company of any installment of interest upon any of the Notes as and when the same shall become due and payable, and such default shall have continued for a period of thirty (30) days, or (b) in case default shall be made in the payment of the principal of or premium, if any, on any of the Notes as and when the same shall have become due and payable, whether at maturity of the Notes or in connection with any redemption or repurchase, by declaration under this Indenture or otherwise, then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Notes, the whole amount that then shall have become due and payable on all such Notes for principal and premium, if any, or interest, or both, as the case may be, with interest upon the overdue principal and premium, if any, and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest at the rate borne by the Notes; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, and any expenses or liabilities incurred by the Trustee hereunder other than through its negligence or bad faith. Until such demand by the Trustee, the Company may pay the principal of and premium, if any, and interest on the Notes to the registered holders, whether or not the Notes are overdue. -43- In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company or any other obligor on the Notes wherever situated the monies adjudged or decreed to be payable. In the case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the case of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes 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 pursuant to the provisions of this Section 7.2, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest owing and unpaid in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee and of the Noteholders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 8.6; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Noteholders 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 Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property which the holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof on any trial or other proceeding relative thereto, and any such suit or 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 Notes. -44- In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such proceedings. SECTION 7.3. APPLICATION OF MONIES COLLECTED BY TRUSTEE. Any monies collected by the Trustee pursuant to this Article 7 shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon 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 8.6; Second: Subject to the provisions of Article 4, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on the Notes in default 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 Notes, such payments to be made ratably to the persons entitled thereto; Third: Subject to the provisions of Article 4, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid, to the payment of the whole amount then owing and unpaid upon the Notes 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 Notes; and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and premium, if any, and interest without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal and premium, if any, and accrued and unpaid interest; and Fourth: Subject to the provisions of Article 4, to the payment of the remainder, if any, to the Company or any other person lawfully entitled thereto. SECTION 7.4. PROCEEDINGS BY NOTEHOLDER. No holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the holders of not less than 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such indemnity as may be reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for sixty (60) days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no direction inconsistent with such written request shall have been given to the Trustee -45- pursuant to Section 7.7; it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee, that no one or more holders of Notes 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 holder of Notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Notes (except as otherwise provided herein). For the protection and enforcement of this Section 7.4, each and every Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any holder of any Note to receive payment of the principal of and premium, if any, and interest on such Note, on or after the respective due dates expressed in such Note, or to institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such holder. Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the consent of either the Trustee or the holder of any other Note, in his own behalf and for his own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, his rights of conversion as provided herein. SECTION 7.5. PROCEEDINGS BY TRUSTEE. In case of an Event of Default the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. SECTION 7.6. REMEDIES CUMULATIVE AND CONTINUING. Except as provided in the last paragraph of Section 2.6, all powers and remedies given by this Article 7 to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any default or Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein; and, subject to the provisions of Section 7.4, every power and remedy given by this Article 7 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders. SECTION 7.7. DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY OF NOTEHOLDERS. The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.4 shall have the right to direct the time, method, and place of conducting any proceeding for any remedy -46- available to the Trustee or exercising any trust or power conferred on the Trustee; PROVIDED, HOWEVER, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.4 may on behalf of the holders of all of the Notes waive any past default or Event of Default hereunder and its consequences except (i) a default in the payment of interest or premium, if any, on, or the principal of, the Notes when due, (ii) a failure by the Company to convert any Notes into Common Stock or (iii) a default in respect of a covenant or provisions hereof which under Article 11 cannot be modified or amended without the consent of the holders of all Notes then outstanding. Upon any such waiver the Company, the Trustee and the holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Whenever any default or Event of Default hereunder shall have been waived as permitted by this Section 7.7, said default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. SECTION 7.8. NOTICE OF DEFAULTS. The Trustee shall, within ninety (90) days after the occurrence of a default, mail to all Noteholders, as the names and addresses of such holders appear upon the Note register, notice of all defaults known to a Responsible Officer, unless such defaults shall have been cured or waived before the giving of such notice; and provided that, except in the case of default in the payment of the principal of, or premium, if any, or interest on any of the Notes, including without limiting the generality of the foregoing any default in the payment of any Repurchase Price or in the payment of any amount due in connection with any redemption of Notes, then in any such event the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Noteholders. SECTION 7.9. UNDERTAKING TO PAY COSTS. All parties to this Indenture agree, and each holder of any Note 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 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; PROVIDED that the provisions of this Section 7.9 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 9.4, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or premium, if any, or interest on any Note (including, but not limited to, the redemption price or repurchase price with respect to the Notes being redeemed or repurchased as provided in this Indenture) on or after the due date expressed in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 15. -47- SECTION 7.10. DELAY OR OMISSION NOT WAIVER. No delay or omission of the Trustee or of any holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the holders of Notes may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the holders of Notes, as the case may be. ARTICLE 8. CONCERNING THE TRUSTEE SECTION 8.1. DUTIES AND RESPONSIBILITIES OF TRUSTEE. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived) 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 such person's own affairs. No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: (a) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred: (1) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and, after it has been qualified thereunder, the Trust Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and (2) in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any 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 provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture; (b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be provided that the Trustee was negligent in ascertaining the pertinent facts; (c) the Trustee shall not be liable to any Noteholder with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the -48- holders of not less than a majority in principal amount of the Notes at the time outstanding determined as provided in Section 9.4 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; and (d) whether or not therein 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. None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. SECTION 8.2. RELIANCE ON DOCUMENTS, OPINIONS, ETC. Except as otherwise provided in Section 8.1: (a) the Trustee may rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties; (b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers' Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company; (c) the Trustee may consult with counsel of its selection and any advice of such counsel or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby; (e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; PROVIDED, HOWEVER, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely -49- to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require indemnity reasonably satisfactory to the Trustee from the Noteholders against such expenses or liability as a condition to so proceeding; the reasonable expenses of every such examination shall be paid by the Company or, if paid by the Trustee or any predecessor Trustee, shall be repaid by the Company upon demand; (f) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed by it with due care hereunder; (h) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; (i) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; (j) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; and (k) the Trustee may request that the Company deliver an Officers' Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers' Certificate may be signed by any person authorized to sign an Officers' Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. In no event shall the Trustee be liable for any consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action other than through the Trustee's willful misconduct or gross negligence. SECTION 8.3. NO RESPONSIBILITY FOR RECITALS, ETC. The recitals contained herein and in the Notes (except in the Trustee's certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. SECTION 8.4. TRUSTEE, PAYING AGENTS, CONVERSION AGENTS OR REGISTRAR MAY OWN NOTES. The Trustee, any paying agent, any conversion agent or -50- Note registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not Trustee, paying agent, conversion agent or Note registrar. SECTION 8.5. MONIES TO BE HELD IN TRUST. Subject to the provisions of Section 13.4, all monies received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed from time to time in writing by the Company and the Trustee. SECTION 8.6. COMPENSATION AND EXPENSES OF TRUSTEE. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity as shall be agreed in writing between the Company and the Trustee (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust), and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel and of all persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence, willful misconduct or bad faith. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and its agents and any authenticating agent for, and to hold them harmless against, any and all loss, liability, damage, claim or expense, including taxes (other than those based upon, measured by or determined by the income of the Trustee), incurred without negligence, willful misconduct or bad faith on the part of the Trustee or such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability (whether asserted by the Company, any Holder or any other Person) in the premises. The obligations of the Company under this Section 8.6 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except, subject to the effect of Sections 4.3 and 7.6, funds held in trust herewith for the benefit of the holders of particular Notes prior to the date of the accrual of such unpaid compensation or indemnifiable claim. The obligation of the Company under this Section shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee. The indemnification provided in this Section 8.6 shall extend to the officers, directors, agents and employees of the Trustee. When the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 7.1(j) or (k) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws. SECTION 8.7. OFFICERS' CERTIFICATE AS EVIDENCE. Except as otherwise provided in Section 8.1, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking -51- or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers' Certificate delivered to the Trustee, and such Officers' Certificate, in the absence of negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. SECTION 8.8. CONFLICTING INTERESTS OF TRUSTEE. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. SECTION 8.9. ELIGIBILITY OF TRUSTEE. There shall at all times be a Trustee hereunder which shall be a person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus (together with its corporate parent) of at least $50,000,000. If such person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. SECTION 8.10. RESIGNATION OR REMOVAL OF TRUSTEE. (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by mailing notice thereof to the holders of Notes at their addresses as they shall appear on the Note register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment sixty (60) days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may petition any court of competent jurisdiction at the expense of the Company for the appointment of a successor trustee, or any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 7.9, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. (b) In case at any time any of the following shall occur: (1) the Trustee shall fail to comply with Section 8.8 within a reasonable time after written request therefor by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for at least six months, or -52- (2) the Trustee shall cease to be eligible in accordance with the provisions of Section 8.9 and shall fail to resign after written request therefor by the Company or by any such Noteholder, or (3) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, the Company may by a Board resolution remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 7.9, any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within sixty (60) days after the giving of such notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. (c) The holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time remove the Trustee and nominate a successor trustee which shall be deemed appointed as successor trustee unless within ten (10) days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed or any Noteholder, upon the terms and conditions and otherwise as in Section 8.10(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.11. SECTION 8.11. ACCEPTANCE BY SUCCESSOR TRUSTEE. Any successor trustee appointed as provided in Section 8.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.6, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. -53- Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 8.6. No successor trustee shall accept appointment as provided in this Section 8.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 8.8 and be eligible under the provisions of Section 8.9. Upon acceptance of appointment by a successor trustee as provided in this Section 8.11, each of the Company and the former trustee shall mail or cause to be mailed notice of the succession of such trustee hereunder to the holders of Notes at their addresses as they shall appear on the Note register. If the Company fails to mail such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. SECTION 8.12. SUCCESSION BY MERGER, ETC. Any corporation or other entity into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation succeeding to all or substantially all of the corporate trust business of the Trustee such corporation shall be qualified under the provisions of Section 8.8 and eligible under the provisions of Section 8.9. In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; PROVIDED, HOWEVER, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. SECTION 8.13. LIMITATION ON RIGHTS OF TRUSTEE AS CREDITOR. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the Company (or any such other obligor). -54- ARTICLE 9. CONCERNING THE NOTEHOLDERS SECTION 9.1. ACTION BY NOTEHOLDERS. Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the holders of Notes voting in favor thereof at any meeting of Noteholders duly called and held in accordance with the provisions of Article X, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix in advance of such solicitation, a date as the record date for determining holders entitled to take such action. The record date shall be not more than fifteen (15) days prior to the date of commencement of solicitation of such action. SECTION 9.2. PROOF OF EXECUTION BY NOTEHOLDERS. Subject to the provisions of Sections 8.1, 8.2 and 10.5, proof of the execution of any instrument by a Noteholder or his agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note register or by a certificate of the Note registrar. The record of any Noteholders' meeting shall be proved in the manner provided in Section 10.6. SECTION 9.3. WHO ARE DEEMED ABSOLUTE OWNERS. The Company, the Trustee, any authenticating agent, any paying agent, any conversion agent and any Note registrar may deem the person in whose name such Note shall be registered upon the Note register to be, and may treat him as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of, premium, if any, and interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any paying agent nor any conversion agent nor any Note registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon his order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Note. SECTION 9.4. COMPANY-OWNED NOTES DISREGARDED. In determining whether the holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes which are owned by the Company or any other obligor on the Notes or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the Notes shall be disregarded and deemed not to be outstanding for the purpose of any such determination; PROVIDED that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes which a Responsible Officer knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding for the purposes of this Section 9.4 if the pledgee shall establish to the satisfaction of the Trustee the pledgee's right to vote such Notes and that the pledgee is not the Company, any other obligor on the Notes or a person directly or -55- indirectly controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers' Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described persons; and, subject to Section 8.1, the Trustee shall be entitled to accept such Officers' Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

Except as aforesaid, any such action taken by the holder of any Note shall be conclusive and binding upon such holder and upon all future holders and owners of such Note and of any Notes issued in exchange or substitution therefor, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor.

The Company shall not, directly or indirectly, consolidate with or merge with or into any other Person or sell, lease, convey or transfer all its properties and assets substantially as an entirety, whether in a single transaction or a series of related transactions, to any Person or group of affiliated Persons unless: (a) either (i) in the case of a merger or consolidation that does not involve a transfer of all or substantially all of the Company's properties and assets, the Company is the surviving entity or (ii) in case the Company shall consolidate with or merge into another Person or sell, lease, convey or transfer all its properties and assets substantially as an entirety, whether in a single transaction or a series of related transactions, to any Person, the Person formed by such consolidation or into which the Company is merged, or the Person which acquires by sale, conveyance or transfer, or which leases the properties and assets of the Company substantially as an entirety, shall be a corporation, limited liability company, partnership or trust, shall be organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia and shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal of, premium, if any, and interest on all of the Notes as -62- applicable, and the performance or observance of every covenant of this Indenture on the part of the Company to be performed or observed and shall have provided for the applicable conversion rights set forth in Section 15.6 and the repurchase rights set forth in Article 16; (b) immediately after giving effect to such transaction, no Event of Default, and no event that after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing; and (c) the Company has delivered to the Trustee an Officers Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with this Article and that all conditions precedent herein provided for relating to such transaction have been complied with, together with any documents required under Article 9. SECTION 12.2. SUCCESSOR CORPORATION TO BE SUBSTITUTED. In case of any such consolidation, merger, sale, conveyance or lease in accordance with Section 12.1, and, where required in accordance with Section 12.1(a) upon the assumption by the successor corporation, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and premium, if any, and interest on all of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such successor corporation shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such successor corporation thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor corporation instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes which previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Notes which such successor corporation thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or lease, the person named as the "Company" in the first paragraph of this Indenture or any successor which shall thereafter have become such in the manner prescribed in this Article 12 may be dissolved, wound up and liquidated at any time thereafter and such person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture. In case of any such consolidation, merger, sale, conveyance or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. -63- SECTION 12.3. OPINION OF COUNSEL TO BE GIVEN TRUSTEE. The Trustee, subject to Sections 8.1 and 8.2, shall receive an Officers' Certificate and an Opinion of Counsel from the surviving company as conclusive evidence that any such consolidation, merger, sale, conveyance or lease and any such assumption complies with the provisions of this Article 12. ARTICLE 13. SATISFACTION AND DISCHARGE OF INDENTURE SECTION 13.1. DISCHARGE OF INDENTURE. When (a) the Company shall deliver to the Trustee for cancellation all Notes theretofore authenticated (other than any Notes which have been destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Notes not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and the Company shall deposit with the Trustee, in trust, funds sufficient to pay at maturity or upon redemption of all of the Notes (other than any Notes which shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and premium, if any, and interest due or to become due to such date of maturity or redemption date, as the case may be, and if in either case the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect (except as to (i) remaining rights of registration of transfer, substitution and exchange and conversion of Notes, (ii) rights hereunder of Noteholders to receive payments of principal of and premium, if any, and interest on, the Notes and the other rights, duties and obligations of Noteholders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and (iii) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, on demand of the Company accompanied by an Officers' Certificate and an Opinion of Counsel as required by Section 17.5 and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agreeing to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Notes. SECTION 13.2. DEPOSITED MONIES TO BE HELD IN TRUST BY TRUSTEE. Subject to Section 13.4, all monies deposited with the Trustee pursuant to Section 13.1 shall be held in trust and applied by it to the payment, notwithstanding the provisions of Article 4, either directly or through any paying agent (including the Company if acting as its own paying agent), to the holders of the particular Notes for the payment or redemption of which such monies have been deposited with the Trustee, of all sums due and to become due thereon for principal and interest and premium, if any. SECTION 13.3. PAYING AGENT TO REPAY MONIES HELD. Upon the satisfaction and discharge of this Indenture, all monies then held by any paying agent of the Notes (other than the Trustee) shall, upon demand of the Company, be repaid to it or paid to the Trustee, and -64- thereupon such paying agent shall be released from all further liability with respect to such monies. SECTION 13.4. RETURN OF UNCLAIMED MONIES. Subject to the requirements of applicable law, any monies deposited with or paid to the Trustee for payment of the principal of, premium, if any, or interest on Notes and not applied but remaining unclaimed by the holders of Notes for two years after the date upon which the principal of, premium, if any, or interest on such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on demand and all liability of the Trustee shall thereupon cease with respect to such monies; and the holder of any of the Notes shall thereafter look only to the Company for any payment which such holder may be entitled to collect unless an applicable abandoned property law designates another person. SECTION 13.5. REINSTATEMENT. If (i) the Trustee or the paying agent is unable to apply any money in accordance with Section 13.2 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application and (ii) the holders of at least a majority in principal amount of the then outstanding Notes so request by written notice to the Trustee, the Company's obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 13.1 until such time as the Trustee or the paying agent is permitted to apply all such money in accordance with Section 13.2; PROVIDED, HOWEVER, that if the Company makes any payment of interest on or principal of any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the holders of such Notes to receive such payment from the money held by the Trustee or paying agent. ARTICLE 14. IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS SECTION 14.1. INDENTURE AND NOTES SOLELY CORPORATE OBLIGATIONS. No recourse for the payment of the principal of or premium, if any, or interest on any Note, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer or director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes. -65- ARTICLE 15. CONVERSION OF NOTES SECTION 15.1. RIGHT TO CONVERT. Subject to and upon compliance with the provisions of this Indenture, the holder of any Note shall have the right, at his option, at any time following the date of original issuance of the Notes and prior to the close of business on [____________ ___, 2009] (except that, with respect to any Note or portion of a Note which shall be called for redemption, such right shall terminate, except as provided in the fifth paragraph of Section 15.2 and Section 3.4, at the close of business on the Business Day next preceding the date fixed for redemption or repurchase of such Note or portion of a Note unless the Company shall default in payment due upon redemption or repurchase, as applicable, thereof) to convert the principal amount of any such Note, or any portion of such principal amount which is $1,000 or an integral multiple thereof, into that number of fully paid and non-assessable shares of Common Stock (as such shares shall then be constituted) obtained by dividing the principal amount of the Note or portion thereof surrendered for conversion by the Conversion Price in effect at such time, by surrender of the Note so to be converted in whole or in part in the manner provided in Section 15.2. A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder has converted his Notes to Common Stock, and only to the extent such Notes are deemed to have been converted to Common Stock under this Article 15. A Note with respect to which a holder has delivered a notice in accordance with Section 16.2 regarding such holder's election to require the Company to repurchase such holder's Notes following the occurrence of a Repurchase Event may be converted in accordance with this Article 15 only if such holder withdraws such notice by delivering a written notice of withdrawal to the Company prior to the close of business on last Business Day prior to the day fixed for repurchase. SECTION 15.2. EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF COMMON STOCK ON CONVERSION; NO ADJUSTMENT FOR INTEREST OR DIVIDENDS. In order to exercise the conversion privilege with respect to any Note in definitive form, the holder of any such Note to be converted in whole or in part shall surrender such Note, duly endorsed, at an office or agency maintained by the Company pursuant to Section 5.2, accompanied by the funds, if any, required by the penultimate paragraph of this Section 15.2, and shall give written notice of conversion in the form provided on the Notes (or such other notice which is acceptable to the Company) to the office or agency that the holder elects to convert such Note or such portion thereof specified in said notice. Such notice shall also state the name or names (with address) in which the certificate or certificates for shares of Common Stock which shall be issuable on such conversion shall be issued, and shall be accompanied by transfer taxes, if required pursuant to Section 15.7. Each such Note surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same name as the registration of such Note, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or his duly authorized attorney. In order to exercise the conversion privilege with respect to any interest in the Global Note, the beneficial holder must complete the appropriate instruction form for conversion pursuant to the Depositary's book-entry conversion program, deliver by book-entry delivery an interest in the Global Note, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or conversion agent, and pay the funds, if any, required by the penultimate paragraph of this Section 15.2 and any transfer taxes, if required pursuant to Section 15.7. -66- As promptly as practicable after satisfaction of the requirements for conversion set forth above, subject to compliance with any restrictions on transfer if shares issuable on conversion are to be issued in a name other than that of the Noteholder (as if such transfer were a transfer of the Note or Notes (or portion thereof) so converted), the Company shall issue and shall deliver to such holder at the office or agency maintained by the Company for such purpose pursuant to Section 5.2, a certificate or certificates for the number of full shares of Common Stock issuable upon the conversion of such Note or portion thereof in accordance with the provisions of this Article and a check or cash in respect of any fractional interest in respect of a share of Common Stock arising upon such conversion, as provided in Section 15.3 (which payment, if any, shall be paid no later than five Business Days after satisfaction of the requirements for conversion set forth above). In case any Note of a denomination greater than $1,000 shall be surrendered for partial conversion, and subject to Section 2.3, the Company shall execute and the Trustee shall authenticate and deliver to the holder of the Note so surrendered, without charge to him, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note. Each conversion shall be deemed to have been effected as to any such Note (or portion thereof) on the date on which the requirements set forth above in this Section 15.2 have been satisfied as to such Note (or portion thereof), and the person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become on said date the holder of record of the shares represented thereby; PROVIDED, HOWEVER, that any such surrender on any date when the stock transfer books of the Company shall be closed shall constitute the person in whose name the certificates are to be issued as the record holder thereof for all purposes on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the date upon which such Note shall be surrendered. Any Note or portion thereof surrendered for conversion during the period from the close of business on the record date for any interest payment date through the opening of business on the Business Day next preceding such interest payment date shall (unless such Note or portion thereof being converted shall have been called for redemption pursuant to a redemption notice mailed to the Noteholders in accordance with Section 3.2 or eligible for repurchase pursuant to a Company Notice mailed to the Noteholders in accordance with Section 16.2) be accompanied by payment, in New York Clearing House funds or other funds acceptable to the Company, of an amount equal to the interest otherwise payable on such interest payment date on the principal amount being converted; PROVIDED, HOWEVER, that no such payment need be made if there shall exist at the time of conversion a default in the payment of interest on the Notes. Except as provided above in this Section 15.2, no adjustment shall be made for interest accrued on any Note converted or for dividends on any shares issued upon the conversion of such Note as provided in this Article. Upon the conversion of an interest in the Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on the Global Note as to the reduction in the principal amount represented thereby. SECTION 15.3. CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES. No fractional shares of Common Stock or scrip representing fractional shares shall be issued upon -67- conversion of Notes. If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered for conversion. If any fractional share of stock otherwise would be issuable upon the conversion of any Note or Notes, the Company shall make an adjustment therefor in cash at the current market value thereof to the holder of Notes. The current market value of a share of Common Stock shall be the Closing Price on the first Trading Day immediately preceding the day on which the Notes (or specified portions thereof) are deemed to have been converted and such Closing Price shall be determined as provided in Section 15.5(h). SECTION 15.4. CONVERSION PRICE. The conversion price shall be as specified in the form of Note (herein called the "Conversion Price") attached as Exhibit A hereto, subject to adjustment as provided in this Article 15. SECTION 15.5. ADJUSTMENT OF CONVERSION PRICE. The Conversion Price shall be adjusted from time to time by the Company as follows: (a) In case the Company shall hereafter pay a dividend or make a distribution on any class of capital stock of the Company payable in shares of Common Stock, the Conversion Price in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the Record Date (as defined in Section 15.5(h)) fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such reduction to become effective immediately after the opening of business on the day following the Record Date. If any dividend or distribution of the type described in this Section 15.5(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared. (b) In case the Company shall issue rights, options or warrants to all holders of its outstanding shares of Common Stock (other than any rights, options or warrants that by their terms will also be issued to any Noteholder upon conversion of a Note into Common Stock without any action required by the Company or any other person) entitling them to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price (as defined in Section 15.5(h)) on the Record Date fixed for the determination of stockholders entitled to receive such rights, options or warrants, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the date after such Record Date 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 plus the number of shares which the aggregate offering price of the total number of shares so offered for subscription or purchase would purchase at such Current Market Price, and of which the denominator shall be the number of shares of Common Stock outstanding on -68- the close of business on the Record Date plus the total number of additional shares of Common Stock so offered for subscription or purchase. Such adjustment shall become effective immediately after the opening of business on the day following the Record Date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered pursuant to such rights, options or warrants, upon the expiration or termination of such rights or warrants the Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase 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 for such rights or warrants, the value of such consideration, if other than cash, to be determined by the Board of Directors. Not in limitation of the foregoing, in the event that the Company implements a stockholder rights plan, such rights plan shall provide that upon conversion of the Notes the holders will receive, in addition to the Common Stock issuable upon such conversion, the rights issued under such rights plan (notwithstanding the occurrence of an event causing such rights to separate from the Common Stock at or prior to the time of conversion). Any distribution of rights, options or warrants pursuant to a stockholder rights plan complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights, options or warrants for the purposes of this Section 15.5(d). Rights, options or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company's capital stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events ("Trigger Event"): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 15.5(b) (and no adjustment to the Conversion Price under this Section 15.5(b) will be required) until the occurrence of the earliest Trigger Event. If such right, option or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different securities, evidences of indebtedness or other assets or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right, option or warrant (and a termination or expiration of the existing right, option or warrant without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Price under this Section 15.5(b), (1) in the case of any such rights, options or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger -69- Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights, options or warrants all of which shall have expired or been terminated without exercise, the Conversion Price shall be readjusted as if such rights and warrants had never been issued. (c) In case the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company (other than any dividends or distributions to which Section 15.5(a) applies) or evidences of its indebtedness, cash or other assets (including securities, but excluding (1) any rights, options or warrants referred to in Section 15.5(b) and, (2) dividends and distributions exclusively in cash (the foregoing hereinafter in this Section 15.5(d) called the "Securities")), unless the Company elects to reserve such Securities for distribution to the Noteholders upon conversion of the Notes so that any such holder converting Notes will receive upon such conversion, without any additional action on the part of the Company or the Noteholder and in addition to the shares of Common Stock to which such holder is entitled, the amount and kind of such Securities which such holder would have received if such holder had converted its Notes into Common Stock immediately prior to the Record Date (as defined in Section 15.5(h) for such distribution of the Securities) then, in each such case, the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date (as defined in Section 15.5(h)) with respect to such distribution by a fraction of which the numerator shall be the Current Market Price (determined as provided in Section 15.5(h)) on such date less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) on such date of the portion of the Securities so distributed applicable to one share of Common Stock and the denominator shall be such Current Market Price, such reduction to become effective immediately prior to the opening of business on the day following the Record Date; PROVIDED, HOWEVER, that in the event the then fair market value (as so determined) of the portion of the Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon conversion of a Note (or any portion thereof) the amount of Securities such holder -70- would have received had such holder converted such Note (or portion thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 15.5(d) by reference to the actual or when issued trading market for any securities comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the "Reference Period") used in computing the Current Market Price pursuant to Section 15.5(h) to the extent possible, unless the Board of Directors in a Board Resolution determines in good faith that determining the fair market value during the Reference Period would not be in the best interest of the Noteholder. For purposes of this Section 15.5(d) and Sections 15.5(a) and (b), any dividend or distribution to which this Section 15.5(d) is applicable that also includes shares of Common Stock, or rights, options or warrants to subscribe for or purchase shares of Common Stock to which Section 15.5(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants other than such shares of Common Stock or rights or warrants to which Section 15.5(b) applies (and any Conversion Price reduction required by this Section 15.5(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Price reduction required by Sections 15.5(a) and (b) with respect to such dividend or distribution shall then be made, except (A) the Record Date of such dividend or distribution shall be substituted as "the date fixed for the determination of stockholders entitled to receive such dividend or other distribution", "Record Date fixed for such determination" and "Record Date" within the meaning of Section 15.5(a) and as "the date fixed for the determination of stockholders entitled to receive such rights or warrants", "the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants" and "such Record Date" within the meaning of Section 15.5(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the date fixed for such determination" within the meaning of Section 15.5(a). (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is distributed upon a merger or consolidation to which Section 15.6 applies or as part of a distribution referred to in Section 15.5(d)), in an aggregate amount that, combined together with (1) the aggregate amount of any other such distributions to all holders of its Common Stock made exclusively in cash within the twelve (12) months preceding the date of payment of such distribution, and in respect of which no adjustment pursuant to this Section 15.5(e) has been made, and (2) the aggregate of any cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) of consideration payable in respect of any tender offer by the Company or any of its subsidiaries for all or any portion of the Common Stock concluded within the twelve (12) months preceding the date of payment of such distribution, and in respect of which no adjustment pursuant to Section 15.5(f) has been made, exceeds 10% of the product of the Current Market Price (determined as provided in Section 15.5(h)) on the -71- Record Date with respect to such distribution times the number of shares of Common Stock outstanding on such date, then, and in each such case, immediately after the close of business on such date, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on such Record Date by a fraction (i) the numerator of which shall be equal to the Current Market Price on the Record Date less an amount equal to the quotient of (x) the excess of such combined amount over such 10% and (y) the number of shares of Common Stock outstanding on the Record Date and (ii) the denominator of which shall be equal to the Current Market Price on such date; PROVIDED, HOWEVER, that in the event the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon conversion of a Note (or any portion thereof) the amount of cash such holder would have received had such holder converted such Note (or portion thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. Any cash distribution to all holders of Common Stock as to which the Company makes the election permitted by Section 15.5(n) and as to which the Company has complied with the requirements of such Section shall be treated as not having been made for all purposes of this Section 15.5(e)). (f) In case a tender offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender offer) of Purchased Shares (as defined below)) of an aggregate consideration having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) that combined together with (1) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution), as of the expiration of such tender offer, of consideration payable in respect of any other tender offers, by the Company or any of its subsidiaries for all or any portion of the Common Stock expiring within the twelve (12) months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this Section 15.5(f) has been made and (2) the aggregate amount of any distributions to all holders of the Company's Common Stock made exclusively in cash within twelve (12) months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to Section 15.5(e) has been made, exceeds 10% of the product of the Current Market Price (determined as provided in Section 15.5(h)) as of the last time (the "Expiration Time") tenders could have been made pursuant to such tender offer (as it may be amended) times the number of shares of Common Stock outstanding (including any tendered shares) on the Expiration Time, then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time, 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 close of business on the date of the Expiration Time by a fraction of which the numerator shall -72- be the number of shares of Common Stock outstanding (including any tendered shares) on the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, such reduction (if any) to become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender offer had not been made. If the application of this Section 15.5(f) to any tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 15.5(f). Any cash distribution to all holders of Common Stock as to which the Company has made the election permitted by Section 15.5(n) and as to which the Company has complied with the requirements of such Section shall be treated as not having been made for all purposes of this Section 15.5(f). (g) In case of a tender or exchange offer made by a person other than the Company or any Subsidiary for an amount which increases the offeror's ownership of Common Stock to more than 25% of the Common Stock outstanding and shall involve the payment by such person of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors), whose determination shall be conclusive, and described in a Board Resolution at the last time (the "Expiration Time") tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) that exceeds the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, and in which, as of the Expiration Time the Board of Directors is not recommending rejection of the offer, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Expiration Time by a fraction of which the numerator shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) on the Expiration Time multiplied by the current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, such reduction to become effective immediately prior to the opening of business on the -73- day following the Expiration Time. In the event that such person is obligated to purchase shares pursuant to any such tender or exchange offer, but such person is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment described in this Section 15.5(g) shall not be made if, as of the Expiration Time, the offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Article 12. (h) For purposes of this Section 15.5, the following terms shall have the meaning indicated: (1) "Closing Price" with respect to any securities on any day shall mean the closing sale price regular way on such day or, in case no such sale takes place on such day, the average of the reported closing bid and asked prices, regular way, in each case on the Nasdaq National Market or New York Stock Exchange, as applicable, or, if such security is not listed or admitted to trading on such National Market or Exchange, on the principal national security exchange or quotation system on which such security is quoted or listed or admitted to trading, or, if not quoted or listed or admitted to trading on any national securities exchange or quotation system, the average of the closing bid and asked prices of such security on the over-the-counter market on the day in question as reported by the National Quotation Bureau Incorporated, or a similar generally accepted reporting service, or if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to time by the Board of Directors for that purpose, or a price determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution. (2) "Current Market Price" shall mean the average of the daily Closing Prices per share of Common Stock for the ten (10) consecutive Trading Days immediately prior to the date in question; PROVIDED, HOWEVER, that (1) if the "ex" date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 15.5(a), (b), (c), (d), (e), (f) or (g) occurs during such ten (10) consecutive Trading Days, the Closing Price for each Trading Day prior to the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event, (2) if the "ex" date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 15.5(a), (b), (c), (d), (e), (f) or (g) occurs on or after the "ex" date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be -74- adjusted as a result of such other event, and (3) if the "ex" date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Closing Price for each Trading Day on or after such "ex" date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 15.5(d), (f) or (g), whose determination shall be conclusive and described in a Board Resolution) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such "ex" date. For purposes of any computation under Sections 15.5(f) or (g), the Current Market Price of the Common Stock on any date shall be deemed to be the average of the daily Closing Prices per share of Common Stock for such day and the next two succeeding Trading Days; PROVIDED, HOWEVER, that if the "ex" date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 15.5(a), (b), (c), (d), (e), (f) and (g) occurs on or after the Expiration Time for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term "ex" date, (1) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution, (2) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and (3) when used with respect to any tender or exchange offer means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer. Notwithstanding the foregoing, whenever successive adjustments to the Conversion Price are called for pursuant to this Section 15.5, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 15.5 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors. (3) "fair market value" shall mean the amount which a willing buyer would pay a willing seller in an arm's length transaction. (4) "Record Date" shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other -75- property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). (5) "Trading Day" shall mean (x) if the applicable security is listed or admitted for trading on the New York Stock Exchange or another national security exchange, a day on which the New York Stock Exchange or another national security exchange is open for business or (y) if the applicable security is quoted on the Nasdaq National Market, a day on which trades may be made thereon or (z) if the applicable security is not so listed, admitted for trading or quoted, any day other than a Saturday or Sunday or a day on which banking institutions in the State of New York are authorized or obligated by law or executive order to close. (i) The Company may make such reductions in the Conversion Price, in addition to those required by Sections 15.5(a), (b), (c), (d), (e), (f) and (g), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. To the extent permitted by applicable law, the Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least twenty (20) days, the reduction is irrevocable during the period and the Board of Directors shall have made a determination that such reduction would be in the best interests of the Company, which determination shall be conclusive and described in a Board Resolution. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to the holder of each Note at his last address appearing on the Note register provided for in Section 2.5 a notice of the reduction at least fifteen (15) days prior to the date the reduced Conversion Price takes effect, and such notice shall state the reduced Conversion Price and the period during which it will be in effect. (j) 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 Section 15.5(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 15 shall be made by the Company and shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be. No adjustment need be made for a change in the par value or no par value of the Common Stock. (k) Whenever the Conversion Price is adjusted as herein provided, the Company shall promptly file with the Trustee and any conversion agent other than the Trustee an Officers' Certificate setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Price setting forth the adjusted Conversion Price and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Price -76- to the holder of each Note at his last address appearing on the Note register provided for in Section 2.5, within twenty (20) days of the effective date of such adjustment. Failure to deliver such notice shall not effect the legality or validity of any such adjustment. (l) In any case in which this Section 15.5 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 Note converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 15.3. (m) For purposes of this Section 15.5, 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 will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. (n) In lieu of making any adjustment to the Conversion Price pursuant to Section 15.5(e), the Company may elect to reserve an amount of cash for distribution to the holders of the Notes upon the conversion of the Notes so that any such holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock and other items to which such holder is entitled, the full amount of cash which such holder would have received if such holder had, immediately prior to the Record Date for such distribution of cash, converted its Notes into Common Stock, together with any interest accrued with respect to such amount, in accordance with this Section 15.5(n). The Company may make such election by providing an Officers' Certificate to the Trustee to such effect on or prior to the payment date for any such distribution and depositing with the Trustee on or prior to such date an amount of cash equal to the aggregate amount the holders of the Notes would have received if such holders had, immediately prior to the Record Date for such distribution, converted all of the Notes into Common Stock. Any such funds so deposited by the Company with the Trustee shall be invested by the Trustee in marketable obligations issued or fully guaranteed by the United States government with a maturity not more than three (3) months from the date of issuance. Upon conversion of Notes by a holder, the holder will be entitled to receive, in addition to the Common Stock issuable upon conversion, an amount of cash equal to the amount such holder would have received if such holder had, immediately prior to the Record Date for such distribution, converted its Note into Common Stock, along with such holder's pro rata share of any accrued interest earned as a consequence of the investment of such funds. Promptly after making an election pursuant to this Section 15.5(n), the Company shall give or shall cause to be given notice to all Noteholders of such election, which notice shall state the amount of cash per $1,000 principal amount of Notes such holders shall be entitled to receive (excluding interest) upon conversion of the Notes as a consequence of the Company having made such election. -77- SECTION 15.6. EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE. If any of the following events occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (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, merger or combination of the Company with another corporation as a result of which holders of Common Stock 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 the properties and assets of the Company as, or substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that such Note 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, consolidation, merger, combination, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Notes (assuming, for such purposes, a sufficient number of authorized shares of Common Stock available to convert all such Notes) immediately prior to such reclassification, change, consolidation, merger, combination, sale or conveyance assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purposes of this Section 15.6 the kind and amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments PROVIDED for in this Article 15. If, in the case of any such reclassification, change, consolidation, merger, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock include shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in Article 16 herein. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each holder of Notes, at his address appearing on the Note register provided for in Section 2.5 of this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. -78- The above provisions of this Section shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. If this Section 15.6 applies to any event or occurrence, Section 15.5 shall not apply. SECTION 15.7. TAXES ON SHARES ISSUED. The issue of stock certificates on conversions of Notes shall be made without charge to the converting Noteholder for any tax in respect of the issue thereof. 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 stock in any name other than that of the holder of any Note converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. SECTION 15.8. RESERVATION OF SHARES; SHARES TO BE FULLY PAID; LISTING OF COMMON STOCK. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares to provide for the conversion of the Notes from time to time as such Notes are presented for conversion. Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Notes, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Price. The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. The Company further covenants that if at any time the Common Stock shall be listed on the Nasdaq National Market or any other national securities exchange or automated quotation system the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, all Common Stock issuable upon conversion of the Notes. SECTION 15.9. RESPONSIBILITY OF TRUSTEE. The Trustee and any other conversion agent shall not at any time be under any duty or responsibility to any holder of Notes to determine whether any facts exist which may require any adjustment of the Conversion Price, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other conversion agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other conversion agent make no representations with respect thereto. Subject to the provisions of Section 8.1, neither the Trustee nor any conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash -79- upon the surrender of any note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any conversion agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 15.6 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 15.6 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 8.1, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers' Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. SECTION 15.10. NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS. In case: (a) the Company shall declare a dividend (or any other distribution) on its Common Stock (that would require an adjustment in the Conversion Price pursuant to Section 15.5); or (b) the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or (c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any 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; the Company shall cause to be filed with the Trustee and to be mailed to each holder of Notes at his address appearing on the Note register, provided for in Section 2.5 of this Indenture, as promptly as possible but in any event at least fifteen days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or 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 or rights 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 or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. -80- ARTICLE 16. REPURCHASE UPON A REPURCHASE EVENT SECTION 16.1. REPURCHASE RIGHT. (a) If, at any time prior to [____________ ___, 2009] there shall occur a Repurchase Event, then each Noteholder shall have the right, at such holder's option, to require the Company to repurchase all of such holder's Notes, or any portion thereof (in principal amounts of $1,000 or integral multiples thereof), on the date (the "repurchase date") that is forty (40) calendar days after the date of the Company Notice (as defined in Section 16.2 below) of such Repurchase Event (or, if such 40th day is not a Business Day, the next succeeding Business Day). Such repurchase shall be made in cash at a price equal to 105% of the principal amount of Notes such holder elects to require the Company to repurchase, together with accrued interest, if any, to the repurchase date (the "Repurchase Price") (or, at the option of the Company, by delivery of Common Stock in accordance with the provisions of Section 16.3); PROVIDED, HOWEVER, that if such repurchase date is [__________ or __________] then the interest payable on such date shall be paid to the holder of record of the Note on the next preceding [__________ or ____________], respectively. No Notes may be redeemed at the option of holders upon a Repurchase Event if there has occurred and is continuing an Event of Default, other than a default in the payment of the Repurchase Price with respect to such Notes on the repurchase date. SECTION 16.2. NOTICES; METHOD OF EXERCISING REPURCHASE RIGHT, ETC. (a) Unless the Company shall have theretofore called for redemption all of the outstanding Notes, on or before the fifteenth (15th) calendar day after the occurrence of a Repurchase Event, the Company or, at the written request of the Company, the Trustee, shall mail to all holders of record of the Notes a notice (the "Company Notice") in the form as prepared by the Company of the occurrence of the Repurchase Event and of the repurchase right set forth herein arising as a result thereof. The Company shall also deliver a copy of such notice of a repurchase right to the Trustee and cause a copy of such notice of a repurchase right, or a summary of the information contained therein, to be published once in a newspaper of general circulation in The City of New York. The Company Notice shall contain the following information: (1) the repurchase date, (2) the date by which the repurchase right must be exercised, (3) the last date by which the election to require repurchase, if submitted, must be revoked; (4) the Repurchase Price and whether the Repurchase Price shall be payable in cash or Common Stock and, if payable in Common Stock, the method -81- of calculating the amount of the Common Stock to be delivered upon the repurchase as provided in Section 16.3(a); (5) a description of the procedure which a holder must follow to exercise a repurchase right, and (6) the Conversion Price then in effect, the date on which the right to convert the principal amount of the Notes to be repurchased will terminate and the place or places where Notes may be surrendered for conversion. No failure of the Company to give the foregoing notices or defect therein shall limit any holder's right to exercise a repurchase right or affect the validity of the proceedings for the repurchase of Notes. If any of the foregoing provisions are inconsistent with applicable law, such law shall govern. (b) To exercise a repurchase right, a holder shall deliver to the Trustee on or before the thirty-fifth (35th) day after the Company Notice was delivered (i) written notice to the Company (or agent designated by the Company for such purpose) of the holder's exercise of such right, which notice shall set forth the name of the holder, the principal amount of the Notes to be repurchased, a statement that an election to exercise the repurchase right is being made thereby, and, in the event that the Repurchase Price shall be paid in shares of Common Stock, the name or names (with addresses) in which the certificate or certificates for shares of Common Stock shall be issued, and (ii) the Notes with respect to which the repurchase right is being exercised, duly endorsed for transfer to the Company. Election of repurchase by a holder shall be revocable at any time prior to, but excluding, the repurchase date, by delivering written notice to that effect to the Trustee prior to the close of business on the Business Day prior to the repurchase date. (c) If the Company fails to repurchase on the repurchase date any Notes (or portions thereof) as to which the repurchase right has been properly exercised, then the principal of such Notes shall, until paid, bear interest to the extent permitted by applicable law from the repurchase date at the rate borne by the Note and each such Note shall be convertible into Common Stock in accordance with this Indenture (without giving effect to Section 16.2(b)) until the principal of such Note shall have been paid or duly provided for. (d) Any Note which is to be repurchased only in part shall be surrendered to the Trustee duly endorsed for transfer to the Company and accompanied by appropriate evidence of genuineness and authority 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 Note without service charge, a new Note or Notes, containing identical terms and conditions, of any authorized denomination as requested by such holder in aggregate -82- principal amount equal to and in exchange for the unrepurchased portion of the principal of the Note so surrendered. (e) On or 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 5.4) the Repurchase Price in cash for payment to the holder on the repurchase date; PROVIDED that if payment is to be made in cash, such cash payment is made on the repurchase date it must be received by the Trustee or paying agent, as the case may be, by 10:00 a.m., New York City time, on such date; PROVIDED FURTHER that if the Repurchase Price is to be paid in shares of Common Stock, such shares of Common Stock are to be issued as promptly after the repurchase date as practicable. (f) Any issuance of shares of Common Stock in respect of the Repurchase Price shall be deemed to have been effected immediately prior to the close of business on the repurchase date and the person or persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such repurchase shall be deemed to have become on the repurchase date the holder or holders of record of the shares represented thereby; PROVIDED, HOWEVER, that any surrender for repurchase on a date when the stock transfer books of the Company shall be closed shall constitute the person or persons in whose name or names the certificate or certificates for such shares are to be issued as the record holder or holders thereof for all purposes at the opening of business on the next succeeding day on which such stock transfer books are open. No payment or adjustment shall be made for dividends or distributions on any Common Stock issued upon repurchase of any Security declared prior to the repurchase date. (g) No fractions of shares shall be issued upon repurchase of Notes. If more than one Note shall be repurchased from the same holder and the Repurchase Price shall be payable in shares of Common Stock, the number of full shares which shall be issuable upon such repurchase shall be computed on the basis of the aggregate principal amount of the Notes so repurchased. Instead of any fractional share of Common Stock which would otherwise be issuable on the repurchase of any Note or Notes, the Company will deliver to the applicable holder its check for the current market value of such fractional share.

THE BANK OF NEW YORK, as Trustee By: -------------------------- Authorized Signatory A-4 [FORM OF REVERSE] This Note is one of a duly authorized issue of securities of the Company designated as its "6 3/4% Convertible Subordinated Notes due 2009" (herein called the "Notes"), limited in aggregate principal amount to U.S. [$38,180,000], issued and to be issued under an Indenture, dated as of [____________ ___], 2004 (herein called the "Indenture"), between the Company and The Bank of New York, as Trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture) to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the holders of senior indebtedness and the holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes of any authorized denominations as requested by the holder surrendering the same upon surrender of the Note or Notes to be exchanged, initially, at the Corporate Trust Office of the Trustee. The Trustee upon such surrender by the holder will issue the new Notes in the requested denominations. No sinking fund is provided for the Notes. The Notes are subject to Provisional Redemption by the Company, in whole or in part, at any time on or after [____________ ___, 2005], upon notice as set forth in Section 3.2 of the Indenture, at a redemption price equal to $1,000 per Note to be redeemed plus accrued and unpaid interest, if any, to the Provisional Redemption Date if the closing price of the Common Stock shall have exceeded 150% of the Conversion Price then in effect for at least 20 Trading Days in any consecutive 30-Trading Day period ending on the Trading Day prior to the Notice Date.

A-5 None of the Company, the Trustee, the Note registrar or any co-registrar shall be required to exchange or register a transfer of (a) any Notes for a period of fifteen (15) days next preceding any selection of Notes to be redeemed or (b) any Notes called for redemption or, if a portion of any Note is selected or called for redemption, such portion thereof selected or called for redemption or (c) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (d) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in connection with a Repurchase Event. In any case where the due date for the payment of the principal of, premium, if any, or interest on any Note or the last day on which a holder of a Note has a right to convert his Note shall not be a Business Day, then payment of principal, premium, if any, interest or delivery for conversion of such Note need not be made on or by such date at such place but may be made on or by the next succeeding Business Day, with the same force and effect as if made on the date for such payment or the date fixed for redemption or repurchase, or by such last day for conversion, and no interest shall accrue on the amount so payable for the period after such date. Subject to and upon compliance with the provisions of the Indenture, the holder of this Note is entitled, at his option, at any time following the original issue date of the Notes and on or before the close of business on the Business Day immediately preceding [____________ ___, 2009], or in case this Note or a portion hereof is called for redemption or the holder hereof has exercised his right to require the Company to repurchase this Note or such portion hereof, then in respect of this Note until but (unless the Company defaults in making the payment due upon redemption or repurchase, as the case may be) not after, the close of business on Business Day immediately preceding the any optional redemption date or Provisional Redemption Date or the date fixed for repurchase, as the case may be, to convert this Note (or any portion of the principal amount hereof that is an integral multiple of U.S.$1,000, provided that the unconverted portion of such principal amount is U.S.$1,000 or any integral multiple of U.S.$1,000 in excess thereof) into fully paid and nonassessable shares of Common Stock of the Company at an initial Conversion Price of $1.85 per share of Common Stock (or at the current adjusted Conversion Price if an adjustment has been made as provided in the Indenture, including pursuant to Section 15.5 of the Indenture) by surrender of this Note, duly endorsed and, in case such surrender shall be made during the period from the close of business on any record date next preceding any interest payment date to the opening of business on such Interest Payment Date (except if this Note or portion thereof has been called for redemption on a Provisional Redemption Date or optional redemption date or is repurchasable on a date fixed for repurchase), 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 Note then being converted, and also the conversion notice hereon duly executed, to the Company at the Corporate Trust Office of the Trustee, or at such other office or agency of the Company, subject to any laws or regulations applicable thereto and subject to the right of the Company to terminate the appointment of any Conversion Agent (as defined below) as may be designated by it for such purpose in the Borough of Manhattan, The City of New York, or at such other offices or agencies as the Company may designate (each, a "Conversion Agent"), provided, however, that if this Note or portion hereof has been called for redemption on a Provisional Redemption Date or optional redemption date or is repurchasable on a repurchase rate, then the holder of this Note on such record date will be entitled to receive the interest A-6 accruing hereon from the interest payment date next preceding the date of such conversion to such succeeding interest payment date and the holder of this Note who converts this Note or a portion hereof during such period shall not be required to pay such interest upon surrender of this Note for conversion. Subject to the provisions of the preceding sentence, no cash payment or adjustment is to be made on conversion for interest accrued hereon from the interest payment date next preceding the day of conversion, or for dividends on the Common Stock issued on conversion hereof. The Company shall thereafter deliver to the holder the fixed number of shares of Common Stock (together with any cash adjustment, as provided in the Indenture) into which this Note is convertible and such delivery will be deemed to satisfy the Company's obligation to pay the principal amount of this Note. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional interest (calculated to the nearest 1/100th of a share) the Company shall pay a cash adjustment as provided in the Indenture. The Conversion Price is subject to adjustment as provided in the Indenture. In addition, the Indenture provides that in case of certain consolidations or mergers to which the Company is a party (other than a consolidation or merger that does not result in any reclassification, conversion, exchange or cancellation of the Common Stock) or the conveyance, transfer, sale or lease of all or substantially all of the property and assets of the Company, the Indenture shall be amended, without the consent of any holders of Notes, so that this Note, if then outstanding, will be convertible thereafter, during the period this Note shall be convertible as specified above, only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, transfer, sale or lease by a holder of the number of shares of Common Stock of the Company into which this Note could have been converted immediately prior to such consolidation, merger, conveyance, transfer, sale or lease (subject to the provisions of, and as more explicitly set forth in, the Indenture). No adjustment in the Conversion Price will be made until such adjustment would require an increase or decrease of at least one percent of such price, provided that any adjustment that would otherwise be made will be carried forward and taken into account in the computation of any subsequent adjustment. If a Repurchase Event occurs, the holder of this Note, at the holder's option, shall have the right, in accordance with the provisions of the Indenture, to require the Company to repurchase this Note (or any portion of the principal amount hereof that is at least $1,000 or an integral multiple) for cash at a price equal to 105% of the principal amount thereof plus interest accrued to the repurchase date. At the option of the Company, the Repurchase Price may be paid in cash or, subject to the conditions provided in the Indenture, by delivery of shares of Common Stock having a fair market value equal to the Repurchase Price. For purposes of this paragraph, the fair market value of shares of Common Stock shall be determined by the Company and shall be equal to 95% of the average of the Closing Prices Per Share for the five consecutive Trading Days immediately preceding and including the third Trading Day prior to the repurchase date. Whenever in this Note there is a reference, in any context, to the principal of any Note as of any time, such reference shall be deemed to include reference to the Repurchase Price payable in respect of such Note to the extent that such Repurchase Price is, was or would be so payable at such time, and express mention of the Repurchase Price in any provision of this Note shall not be construed as excluding the Repurchase Price so payable in those provisions of this Note when such express mention is not made; provided, however, that, for the purposes of the second succeeding paragraph, such reference shall be deemed to include reference to the Repurchase Price only to the extent the Repurchase Price is payable in cash. A-7 [The following paragraph shall appear in each Global Security: In the event of a deposit or withdrawal of an interest in this Note, including an exchange, transfer, redemption, repurchase or conversion of this Note in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the rules and procedures of The Depository Trust Company applicable to, and as in effect at the time of, such transaction.] [The following paragraph shall appear in each Note that is not a Global Security: In the event of redemption, repurchase or conversion of this Note in part only, a new Note or Notes for the unredeemed, unrepurchased or unconverted portion hereof will be issued in the name of the holder hereof.] The indebtedness evidenced by this Note is, to the extent and in the manner provided in the Indenture, subordinate and subject in right of payment to the prior payment in full in cash of all senior indebtedness of the Company, and this Note is issued subject to such provisions of the Indenture with respect thereto. Each holder of this Note, 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.
