None of the Company, the Trustee or any paying agent shall have any responsibility or liability for any aspect of the records relating to or payment made on account of beneficial ownership interests in the Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months.

Any interest on any Note that is payable, but is not punctually paid or duly provided for, on any said April 15, or October 15, (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Noteholder on the relevant record date by virtue of his having been such Noteholder; and such Defaulted Interest shall be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest to be paid on each Note and the date of the payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time, the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the persons entitled to such Defaulted Interest as in this clause provided. Thereupon, the Trustee shall fix a special record date for the payment of such Defaulted Interest, which shall be not more than 15 days and not less than 10 days prior to the date of the payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such special record date and, in the name and at the expense of the Company, shall cause notice of the payment of such Defaulted Interest and the special record date therefor to be mailed, first-class postage prepaid, to each Noteholder at his address as it appears in the Note register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the persons in whose names the Notes (or their respective Predecessor Notes) were registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (2).

(2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Section 2.4 EXECUTION OF NOTES. The Notes shall be signed in the name and on behalf of the Company by the signature of its Chief Executive Officer, President, Chief Operating Officer or Chief Financial Officer and attested by the signature of its Treasurer, Secretary or any of its Assistant Secretaries (any of which signatures may be printed, engraved or otherwise reproduced thereon, by facsimile or otherwise). Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, manually executed by the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 16.14), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture.

In case any officer of the Company who shall have signed any of the Notes shall cease to be such officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such officer of the Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person was not such an officer.

Section 2.5 EXCHANGE AND TRANSFER OF NOTES; RESTRICTIONS ON TRANSFER; DEPOSITORY.

Any exchange or transfer of all or a part of the Global Note for definitive Notes pursuant to this Section 2.5 will be accompanied by a supplemental indenture that will include the form of such definitive Notes and provisions for conversion of the Notes under Article XIV.

(a) The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company designated pursuant to Section 4.2 being herein sometimes collectively referred to as the “Note register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the transfers of Notes. Such Note register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby appointed “Note registrar” for the purpose of transfers of Notes as herein provided. The Company may appoint one or more co-registrars.

Upon surrender for registration of transfer of any Note to the Note registrar or any co-registrar and satisfaction of the requirements for such transfer set forth in this Section 2.5, the Company shall execute, and the Trustee shall authenticate and make available for delivery, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount may be required by Section 2.5(b).

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall

execute, and the Trustee shall authenticate and make available for delivery, the Notes that the Noteholder making the exchange is entitled to receive bearing certificate numbers not contemporaneously outstanding.

All Notes presented or surrendered for registration of transfer or for exchange shall (if so required by the Company, the Trustee, the Note registrar or any co-registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company, executed by the Noteholder thereof or his attorney duly authorized in writing.

No service charge shall be charged to the Noteholder for any exchange or registration of transfer of Notes, but the Company may require payment of a sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in connection therewith.

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 15 days next preceding the mailing of a notice of redemption, (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, (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 surrendered for repurchase pursuant to Section 3.5 or, if a portion of any Note is surrendered for repurchase pursuant to Section 3.5, such portion thereof surrendered for repurchase pursuant to Section 3.5.

All Notes issued upon any transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. All Notes, the transfer and/or exchange of which is effectuated by the Trustee pursuant to this Section 2.5, shall be accompanied by an Officers’ Certificate of the Company, certifying that such transfer, exchange and/or registration is authorized by the Company and permitted hereunder.

Any transfer of a beneficial interest in the Global Note that cannot be effected through book-entry settlement must be effected by the delivery to the transferee (or its nominee) of a definitive Note or Notes registered in the name of the transferee (or its nominee) on the books maintained by the Trustee, in accordance with the transfer instructions set forth herein. With respect to any such transfer, the Trustee or the Custodian, at the direction of the Trustee, shall cause, in accordance with the standing instructions and procedures existing between the Depository and the Custodian, the aggregate principal amount of the Global Note to be reduced by the principal amount of the beneficial interest in the Note being transferred and, following such reduction, the Company shall execute and the Trustee shall authenticate and make available for delivery to the transferee (or such transferee’s nominee, as the case may be), a definitive Note or Notes in the appropriate aggregate principal amount in the name of such transferee (or its nominee).

Any transfer of a definitive Note or Notes must be effected by the delivery to the transferee (or its nominee) of a definitive Note or Notes registered in the name of the transferee (or its nominee) on the books maintained by the Trustee. With respect to any such transfer, the

Company shall execute and the Trustee shall authenticate and make available for delivery to the transferee (or such transferee’s nominee, as the case may be), a definitive Note or Notes in the appropriate aggregate principal amount in the name of such transferee (or its nominee) and bearing such restrictive legends as may be required by this Indenture.

(b) Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.5(b)), the Global Note may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

The Depository shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depository with respect to the Global Note. Initially, the Global Note shall be issued to the Depository, registered in the name of Cede, as the nominee of the Depository, and deposited with the Trustee as Custodian for Cede.

Neither the Company nor the Trustee (or any registrar, paying agent or conversion agent under this Indenture) shall have responsibility for the performance by the Depository or its participants or indirect participants of its respective obligations under the rules and procedures governing its operations. The Depository will take any action permitted to be taken by a holder of Notes (including, without limitation, the presentation of Notes for exchange as described below) only at the direction of one or more participants to whose account with the Depository interests in the Global Note are credited, and only in respect of the principal amount of the Notes represented by the Global Note as to which such participant or participants has or have given such direction.

If at any time the Depository for the Global Note notifies the Company that it is unwilling or unable to continue as Depository for such Notes, the Company may appoint a successor Depository with respect to such Notes. If a successor Depository for the Notes is not appointed by the Company within 90 days after the Company receives such notice, the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate for the authentication and delivery of Notes, shall authenticate and make available for delivery, Notes in definitive form, in an aggregate principal amount equal to the principal amount of the Global Note in exchange for the Global Note.

Definitive Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.5(b) shall be registered in such names and in such authorized denominations as the Depository, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall make available for delivery such definitive Notes to the persons in whose names such definitive Notes are so registered.

At such time as all interest in the Global Note has been redeemed, converted, repurchased or canceled, the Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and instructions existing between the Depository and the Custodian. At any time prior to such cancellation, if any interest in the Global Note is

exchanged for definitive Notes, redeemed, repurchased, converted, canceled 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 Depository and the Custodian, be 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.

The Company and the Trustee may for all purposes, including the making of payments due on the Notes, deal with the Depository as the authorized representative of the Noteholders for the purposes of exercising the rights of Noteholders hereunder. The rights of the owner of any beneficial interest in the Global Note shall be limited to those established by law and agreements between such owners and depository participants; provided that no such agreement shall give any rights to any person against the Company or the Trustee without the written consent of the parties so affected. Multiple requests, and directions from and votes of the Depository, as holder of notes in book-entry form with respect to any particular matter, shall not be deemed inconsistent to the extent they do not represent an amount of notes in excess of those held in the name of the Depository or its nominee.

(c) Each holder or former holder of a Note agrees to indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of such holder’s or former holder’s Note in violation of any provision of this Indenture and/or applicable U.S. federal or state securities law.

Section 2.6 MUTILATED, DESTROYED, LOST OR STOLEN NOTES. 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 make available for delivery 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. The Company may charge such applicant for the expenses of the Company in replacing a Note. 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 from 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.

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 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 that has matured or is about to mature or has been called for redemption or is about to be repurchased or converted into Common Stock or cash 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 from 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.

Every substitute Note issued pursuant to the provisions of this Section 2.6 in lieu of any Note that 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 enforceable by anyone, 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 make available for delivery temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination and shall be 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 shall 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 the Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.2 and the Trustee or such authenticating agent shall authenticate and make available for delivery 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.

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. If required by the Company, the Trustee shall return canceled Notes 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.

Section 2.9 CUSIP NUMBERS. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of redemption as a convenience to holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any change in the CUSIP numbers.

ARTICLE III

REDEMPTION AND REPURCHASE OF NOTES

Section 3.1 REDEMPTION PRICES. The Notes are not redeemable at the option of the Company prior to October 15, 2005. At any time on or after that date, the Notes may be redeemed at the Company’s option, upon notice as set forth in Section 3.2, in whole at any time or in part from time to time, at the redemption price of 100% of principal amount of Notes plus accrued and unpaid interest.

Section 3.2 NOTICE OF REDEMPTION; SELECTION OF NOTES. 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, in the case of any redemption pursuant to Section 3.1, it or, at its written request accompanied by the proposed form of notice of redemption (which must be received by the Trustee at least 45 days prior to the date fixed for redemption 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 30 and not more than 60 days prior to the date fixed 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 subject to the approval of the form of notice by the Trustee 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.

Each such notice of redemption shall identify the Notes to be redeemed (including CUSIP numbers), 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 shall be made upon presentation and surrender of such Notes, that interest accrued to the date fixed for redemption shall be paid as specified in said notice and that on and after said date, interest thereon or on the portion thereof to be redeemed shall 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 shall 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 shall be issued.

On or prior to the Business Day prior to the redemption date specified in the notice of redemption given as provided in this Section 3.2, the Company shall deposit by 11:00 a.m. Eastern Time 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 4.4) an amount of money sufficient to redeem on the redemption date all the Notes so called for redemption (other than those theretofore surrendered for conversion into Common Stock or cash) at the appropriate redemption price, together with accrued interest to the date fixed for redemption. 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 written request or, if then held by the Company, shall be discharged from such trust. If fewer than all the Notes are to be redeemed, the Company shall give the Trustee written notice in the form of an Officers’ Certificate not fewer than 45 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, in its discretion, on a PRO RATA basis. 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 may be) 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.

Upon any redemption of less than all Notes, the Company and the Trustee may treat as outstanding any Notes surrendered for conversion during the period of 15 days next preceding the mailing of a notice of redemption and need not treat as 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. 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 thereon accrued to 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 thereon accrued to 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 or cash and, except as provided in Sections 7.6 and 12.4, 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 thereon to 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 shall be paid and redeemed by the Company at the applicable redemption price, together with interest accrued thereon to the date fixed for redemption; provided that any semi-annual payment of interest becoming due on the date fixed for redemption 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.

Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and make available for delivery 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.

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, with notice to the Trustee, the Company may arrange for the purchase and conversion of any Notes 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 prior to the close of business one Business Day prior to 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 III, the obligation of the Company to pay the redemption price of such Notes, together with interest accrued to 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 shall 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 XIV) surrendered by such purchasers for conversion, 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 loss, liability 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.

Section 3.5 REPURCHASE OF NOTES UPON A CHANGE OF CONTROL.

(a) If a Change of Control shall occur at any time, then each holder of Notes shall have the right to require that the Company repurchase such holder’s Notes in whole or in part in integral multiples of $1,000 at a purchase price (the “Change of Control Purchase Price”) in cash in an amount equal to 101% of the principal amount of such Notes, plus accrued and unpaid interest thereon, if any, to the purchase date (the “Change of Control Purchase Date”) pursuant to the offer described below (the “Change of Control Offer”) and in accordance with the other procedures set forth in this Indenture.

(b) Within 30 days following any Change of Control, the Company shall publish a notice in the Wall Street Journal, notify the Trustee thereof and give written notice of such Change of Control to each holder of Notes, by first-class mail, postage prepaid, at the Noteholder’s address appearing in the Note register, stating, among other things, (i) that a Change of Control has occurred, (ii) the Change of Control Purchase Price, (iii) the Change of Control Purchase Date (which shall be a Business Day no earlier than 30 days nor later than 60 days from the date such notice is mailed, or such later date as is necessary to comply with requirements under the Exchange Act), (iv) that any Note not tendered shall continue to accrue interest and to have all of the benefits of this Indenture, (v) that, unless the Company defaults in the payment of the Change of Control Purchase Price, any Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Purchase Date, (vi) that Noteholders electing to have any Notes purchased pursuant to a Change of Control Offer shall be required to surrender the Notes, with the form entitled “Option of Noteholder to Elect Purchase” on the reverse of the Notes completed, to the Company at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Purchase Date, (vii) that Noteholders shall be entitled to withdraw their election if the Company receives, not later than the close of business on the second Business Day preceding the Change of Control Purchase Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Noteholder, the principal amount of Notes delivered for purchase, and a statement that such Noteholder is withdrawing his election to have such Notes purchased, and (viii) that Noteholders whose Notes are being purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof. The Company shall comply with the requirements of Rule 13e-4 and 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes in connection with a Change of Control.

(c) On the Change of Control Purchase Date, the Company shall, to the extent lawful, (i) accept for payment Notes or portions thereof tendered pursuant to the Change of Control Offer, (ii) deposit with the Trustee in immediately available funds by 11:00 a.m. Eastern Time an amount equal to the Change of Control Purchase Price in respect of all Notes or portions thereof so tendered and (iii) deliver or cause to be delivered to the Trustee the Notes so accepted

together with an Officers’ Certificate stating the Notes or portions thereof tendered to the Company. The Trustee shall promptly mail to each Noteholder of Notes so accepted payment in an amount equal to the purchase price of such Notes, and the Trustee shall promptly authenticate and mail to each Noteholder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note shall be in a principal amount of $1,000 or an integral multiple thereof. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(d) The term “Change in Control” shall mean an event or series of events in which (i) any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) acquires “beneficial ownership” (as determined in accordance with Rule 13d-3 under the Exchange Act), directly or indirectly, of more than 50% of the total Voting Stock of the Company at an Acquisition Price less than the conversion price then in effect with respect to the Notes and (ii) the holders of the Common Stock receive consideration which is not all or substantially all common stock that is (or upon consummation of or immediately following such event or events will be) listed on a United States national securities exchange or approved for quotation on the Nasdaq Stock Market or any similar United States system of automated dissemination of quotations of securities’ prices; provided, however, that any such person or group shall not be deemed to be the beneficial owner of, or to beneficially own, any Voting Stock tendered in a tender offer until such tendered Voting Stock is accepted for purchase under the tender offer.

(e) “Voting Stock” means stock of the class or classes pursuant to which the holders thereof have the general voting power under ordinary circumstances to elect at least a majority of the board of directors, managers or trustees of a corporation (irrespective whether or not at the time stock of any other class or classes shall have or might have voting power by reason of the happening of any contingency).

ARTICLE IV

PARTICULAR COVENANTS OF THE COMPANY

Section 4.1 PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST. The Company covenants and agrees that it shall 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. Any amounts of cash to be given to the Trustee or paying agent shall be deposited with the Trustee or paying agent in immediately available funds by 11:00 a.m. Eastern Time on or before the date such payment is to be made. 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 Note register; provided that, with respect to any holder of Notes with an aggregate principal amount equal to or in excess of $5,000,000, at the request (such request to include appropriate wire instructions) of such holder in writing to the Trustee, interest on such holder’s Notes shall be paid by wire transfer in immediately available funds. An installment of principal or interest shall be considered paid on the date due if the Trustee or paying agent (other than the Company, a Subsidiary of the Company or any Affiliate of any of them) holds on that date money designated for and sufficient to pay the installment of

principal or interest and is not prohibited from paying such money to the holders of the Notes pursuant to the terms of this Indenture.

Section 4.2 MAINTENANCE OF OFFICE OR AGENCY. The Company shall 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 shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such 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 of the Trustee.

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 shall 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 and conversion agent and the Corporate Trust Office of the Trustee, as offices or agencies of the Company for the purposes set forth in the first paragraph of this Section 4.2.

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 7.11(a).

Section 4.3 APPOINTMENTS TO FILL VACANCIES IN TRUSTEE’S OFFICE. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, shall appoint, in the manner provided in Section 7.11, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 4.4 PROVISIONS AS TO PAYING AGENT.

(a) If the Company shall appoint a paying agent other than the Trustee, or if the Trustee shall appoint such a paying agent, the Company or the Trustee, as the case may be, shall cause such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.4:

(1) that it shall hold all sums held by it as such agent for the payment of the principal of, premium, if any, or interest on the Notes (whether such sums have been paid to it by the Company or by any other obligor on the Notes) in trust for the benefit of the holders of the Notes;

(2) that it shall give the Trustee written notice of any failure by the Company (or by any other obligor on the Notes) to make any payment of the principal of, premium, if any, or interest on the Notes when the same shall be due and payable; and

(3) that at any time during the continuance of an Event of Default, upon request of the Trustee, it shall forthwith pay to the Trustee all sums so held in trust.

The Company shall, 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 shall promptly notify the Trustee of any failure to take such action.

(b) If the Company shall act as its own paying agent, it shall, 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 shall 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 4.4 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 4.4, such 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.

(d) Anything in this Section 4.4 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 4.4 is subject to Sections 12.3 and 12.4.

Section 4.5 CORPORATE EXISTENCE. Subject to Article XI, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of any Subsidiary of the Company, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not materially adverse to the holders of the Notes.

Section 4.6 STAY, EXTENSION AND USURY LAWS. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all

benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

NOTEHOLDERS’ LISTS AND REPORTS BY THE COMPANY

Section 5.1 NOTEHOLDERS’ LISTS. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of holders of Notes, the Company and the Trustee, and shall otherwise comply with Trust Indenture Act Section 312(a). If the Trustee is not the Notes registrar, the Company shall furnish to the Trustee on or before at least seven Business Days preceding each interest payment date and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee reasonably may require of the names and addresses of holders of Notes, and the Company shall otherwise comply with Trust Indenture Act Section 312(a).

Section 5.2 REPORTS BY COMPANY. The Company shall deliver to the Trustee within 15 days after it files the same with the Commission, copies of all reports and information (or copies of such portions of any of the foregoing as the Commission may by its rules and regulations prescribe), if any, which the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act or pursuant to the immediately following sentence. So long as at least $5,000,000 aggregate principal amount of Notes remain outstanding, the Company shall file with the Commission such reports as may be required pursuant to Section 13 of the Exchange Act in respect of a security registered pursuant to Section 12 of the Exchange Act, regardless of whether the Company is otherwise required to file such reports. If the Company is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act (or otherwise required to file reports pursuant to the immediately preceding sentence), the Company shall deliver to the Trustee, within 15 days after it would have been required to file such information with the Commission were it required to do so, annual and quarterly financial statements, including any notes thereto (and, in the case of a fiscal year end, an auditors’ report by an independent certified public accounting firm of established national reputation), and a “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in each case substantially equivalent to that which it would have been required to include in such quarterly or annual reports, information, documents or other reports if it had been subject to the requirements of Section 13 or 15(d) of the Exchange Act. The Company shall provide copies of the foregoing materials to the Noteholders to the extent required by the Trust Indenture Act once this Indenture has been qualified.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

ARTICLE VI

DEFAULTS AND REMEDIES

Section 6.1 EVENTS OF DEFAULT. In case one or more of the following Events of Default (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body) shall have occurred and be continuing:

(a) default in the payment of the principal of or premium, if any, on the Notes when due at maturity, upon redemption or otherwise, including failure by the Company to purchase the Notes when required under Section 3.5 (whether or not such payment shall be prohibited by Article XV of this Indenture); or

(b) default in the payment of any installment of interest on the Notes as and when the same shall become due and payable (whether or not such payment shall be prohibited by Article XV of this Indenture), and continuance of such default for a period of 30 days; or

(c) a failure on the part of the Company to duly observe or perform any other covenants or agreements on the part of the Company in this Indenture (other than a default in the performance or breach of a covenant or agreement that is specifically dealt with elsewhere in this Section 6.1) that continues for a period of 90 days after the date on which written notice of such failure, requiring the Company to remedy the same, shall have been given to the Company by the Trustee, or to the Company and a Responsible Officer of the Trustee, by the holders of at least 25% in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.4; or

(d) an event of default occurs under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company or any of its Subsidiaries (or the payment of which is guaranteed by the Company or any of its Subsidiaries), whether such indebtedness or guarantee now exists or shall be created after the date hereof, which default (i) is caused by a failure to pay principal or interest on such indebtedness prior to the expiration of the grace period provided in such indebtedness (a “Payment Default”) or (ii) results in the acceleration of such indebtedness prior to its expressed maturity and, in each case, the principal amount of such indebtedness, together with the principal amount of any other such indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $10,000,000 or more;

(e) final judgments or decrees shall be entered by a court of competent jurisdiction against the Company or any Subsidiary involving liabilities of $25,000,000 or more (singly or in the aggregate) (after deducting the portion of such liabilities accepted by a reputable insurance company) and such final judgments or decrees shall not have been vacated, discharged, satisfied or stayed pending appeal within 60 days from the entry thereof;

(f) the Company 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

(g) an involuntary case or other proceeding shall be commenced against the Company 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 60 consecutive days;

then, and in each and every such case (other than an Event of Default specified in Section 6.1(f) or (g)), 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 8.4, by notice in writing to the Company (and to the Trustee if given by Noteholders), may declare the principal of, premium, if any, on 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 6.1(f) or (g) occurs and is continuing, the principal of all the Notes and the interest accrued thereon shall be immediately due and payable. The foregoing provision 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 sufficient to pay all matured installments of interest upon all Notes and the principal of and premium, if any, on any and all Notes that 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 7.7, and if any and all defaults under this Indenture, other than the nonpayment of principal of, premium, if any, and accrued interest on Notes that shall have become due by acceleration, shall have been cured or waived pursuant to Section 6.7, 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 thereto. The Company shall notify a Responsible Officer of the Trustee, promptly upon becoming aware thereof, of any Event of Default.

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 taken.

Section 6.2 PAYMENTS OF NOTES ON DEFAULT; SUIT THEREFOR. The Company covenants that (a) in case a default shall be made in the payment 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 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 or otherwise, then, upon demand of the Trustee, the Company shall 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 of, premium, if any, or interest, or both, as the case may be, with interest upon the overdue principal, 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.

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 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 6.2, 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 as may be 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 7.7; 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 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 that 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.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or adopt on behalf of any Noteholder any plan of reorganization or arrangement affecting the Notes or the rights of any Noteholder, or to authorize the Trustee to vote in respect of the claim of any Noteholder in any such proceeding.

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.

In any proceedings brought by the Trustee pursuant to this Indenture or any supplement hereto (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 6.3 APPLICATION OF MONIES COLLECTED BY TRUSTEE. Any monies collected by the Trustee pursuant to this Article VI shall be applied in the order following, 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 7.7;

Second: Subject to the provisions of Article XV, 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; and

Third: Subject to the provisions of Article XV, 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 holding and unpaid upon the Notes for principal, 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, 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.

Section 6.4 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 reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for 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 pursuant to Section 6.7; 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, 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 6.4, 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, 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 except as otherwise set forth herein.

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 6.5 PROCEEDINGS BY TRUSTEE. In case of an Event of Default and subject to the provisions of Section 7.7 hereof, 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 6.6 REMEDIES CUMULATIVE AND CONTINUING. Except as provided in Section 2.7, all powers and remedies given by this Article VI to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of such powers and remedies 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 6.4, every power and remedy given by this Article VI 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 6.7 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 8.4) shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee; provided that (a) such direction shall not be in conflict with any rule of law or with this Indenture and (b) the Trustee may take any other action deemed proper by the Trustee that 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 8.4) 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, (ii) a failure by the Company to convert any Notes into Common Stock or cash, as the case may be, or (iii) a default in respect of a covenant or provisions hereof that under Article X cannot be modified or amended without the consent of the holders of all Notes then outstanding. Whenever any default or Event of Default hereunder shall have been waived as permitted by this Section 6.7, 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 and the

Company, the Trustee and the holders of the Notes shall as reasonably possible 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.

Section 6.8 NOTICE OF DEFAULTS. The Trustee shall, within 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 of which a Responsible Officer has actual knowledge, unless such defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of default in the payment of the principal of, premium, if any, or interest on any of the Notes, the Trustee shall be protected in withholding such notice if and so long as a Responsible Officer of the Trustee in good faith determine that the withholding of such notice is in the interests of the Noteholders.

Section 6.9 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 and expenses, 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 6.9 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 8.4 or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of, premium, if any, or interest on any Note 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 XIV.

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 VII.

Section 7.11 RESIGNATION OR REMOVAL OF TRUSTEE.

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.

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 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 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.

(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 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 provided in the next paragraph, may petition any court of competent jurisdiction for an appointment of a successor trustee.

If no successor trustee shall have been so appointed and have accepted appointment within 60 days after removal or the mailing of such notice of resignation to the Noteholders, the Trustee resigning or being removed may petition any court of competent jurisdiction for the appointment of a successor trustee, or, in the case of either resignation or removal, 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 such court for the appointment of a successor trustee.

Section 7.12 ACCEPTANCE BY SUCCESSOR TRUSTEE. Any successor trustee appointed as provided in Section 7.11 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 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 7.7, 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. 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 7.7.

No successor trustee shall accept appointment as provided in this Section 7.12 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 7.9 and eligible under the provisions of Section 7.10.

Upon acceptance of appointment by a successor trustee as provided in this Section 7.12, the Company 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.

Section 7.14 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) and the Trust Indenture Act is applicable hereto, the Trustee shall be subject to the provisions of Trust Indenture Act Section 311(a) or, if applicable, Trust Indenture Act Section 311(b) regarding the collection of the claims against the Company (or any such other obligor).

The

record date shall be not more than 15 days prior to the date of commencement of solicitation of such action.

All such payments so made to any holder for the time being, or upon order of such holder, 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.

The Depository shall be deemed to be the owner of the Global Note for all purposes, including receipt of notices to Noteholders and payment of principal of, premium, if any, and interest on the Notes.

Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.4 if the pledgee shall establish to the satisfaction of the Trustee the pledger’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 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.

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.

(vii) Such defeasance shall not cause the Trustee to have a conflicting interest with respect to any securities of the Company; and

(viii) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee, each stating that all conditions precedent specified herein relating to the defeasance contemplated by this Section 12.1 have been complied with;

provided, that no deposit under clause (i) shall be effective to terminate the obligations of the Company under the Notes or this Indenture prior to the passage of 123 days following such deposit.

Section 12.3 SURVIVAL OF CERTAIN OBLIGATIONS. Notwithstanding the satisfaction and discharge of this Indenture and of the Notes referred to in Section 12.1 or 12.2, the respective obligations of the Company and the Trustee under Sections 2.3, 2.4, 2.5, 2.6, 3.1, 4.2, 5.1, 6.4, 6.9, 7.6, 7.11, 12.5, 12.6, 12.7, Articles XIV and XV shall survive until the Notes are no longer outstanding, and thereafter, the obligations of the Company and the Trustee under Sections 6.9, 7.6, 12.5, 12.6 and 12.7 shall survive. Nothing contained in this Article XII shall abrogate any of the rights, obligations or duties of the Trustee under this Indenture.

Section 12.4 ACKNOWLEDGMENT OF DISCHARGE BY TRUSTEE. Subject to Section 12.7, after (i) the conditions of Section 12.1 or 12.2 have been satisfied, (ii) the Company has paid or caused to be paid all other sums payable hereunder by the Company and (iii) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent referred to in clause (i) above relating to the satisfaction and discharge of this Indenture have been complied with, the Trustee upon written request shall acknowledge in writing the discharge of the Company’s obligations under this Indenture except for those surviving obligations specified in Section 12.3.

Section 12.5 APPLICATION OF TRUST ASSETS. The Trustee shall hold any cash or U.S. Government Obligations deposited with it in the irrevocable trust established pursuant to Section 12.1 or 12.2, as the case may be. The Trustee shall apply the deposited cash or the U.S. Government Obligations, together with earnings thereon in accordance with this Indenture and the terms of the irrevocable trust agreement established pursuant to Section 12.1 or 12.2, as the case may be, to the payment of principal of, premium, if any, and interest on the Notes. The cash or U.S. Government Obligations so held in trust and deposited with the Trustee in compliance with Section 12.1 or 12.2, as the case may be, shall not be part of the trust estate under this Indenture, but shall constitute a separate trust fund for the benefit of all holders entitled thereto. Except as specifically provided herein, the Trustee shall not be requested to

invest any amounts held by it for the benefit of the holders or pay interest on uninvested amounts to any holder.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 12.1 hereof or Section 12.2 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the holders of outstanding Notes.

Section 12.6 REPAYMENT TO THE COMPANY; UNCLAIMED MONEY. Subject to applicable laws governing escheat of such property, and upon termination of the trust established pursuant to Section 12.1 hereof or 12.2 hereof, as the case may be, the Trustee shall promptly pay to the Company upon written request any excess cash or U.S. Government Obligations held by them. Additionally, if amounts for the payment of principal, premium, if any, or interest remains unclaimed for two years, the Trustee shall, upon written request, pay such amounts back to the Company forthwith. Thereafter, all liability of the Trustee with respect to such amounts shall cease. After payment to the Company, holders entitled to such payment must look to the Company for such payment as general creditors unless an applicable abandoned property law designates another person.

Section 12.7 REINSTATEMENT. If the Trustee is unable to apply any cash or U.S. Government Obligations in accordance with Section 12.1 or 12.2 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.1 or 12.2 until such time as the Trustee is permitted to apply all such cash or U.S. Government Obligations in accordance with Section 12.1 or 12.2, as the case may be; provided that if the Company makes any payment of principal of, premium, if any, or interest on any Notes 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 amounts held by the Trustee.

ARTICLE XIII

ARTICLE XIV

CONVERSION OF NOTES

Section 14.1 RIGHT TO CONVERT.

(a) Subject to and upon compliance with the provisions of this Indenture, the holder of any Note shall have the right to convert the principal hereof or any portion of such principal that is $1,000 or an integral multiple thereof, into the Company’s Common Stock at any time following the earlier of (i) May 27, 2003 and (ii) the approval by the Company’s shareholders of an amendment to the Company’s Articles of Incorporation to increase the number of authorized shares of Common Stock to an amount sufficient to cover the conversion of the Notes, the conversion of the Company’s existing notes due in 2003 and 2008, the conversion of the Company’s convertible preferred stock issuable upon execution of the warrants granted to Centre Solutions (Bermuda) Limited and the exercise of outstanding options granted pursuant to the Company’s stock option plan, and prior to the close of business on October 14, 2008 (except that, with respect to any Note or portion of a Note that shall be called for redemption or delivered for repurchase, such right shall terminate at the close of business one Business Day immediately 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 thereof). The principal amount of any such Note, or any portion of such principal amount that is $1,000 or an integral multiple thereof, is convertible into that number of fully paid and nonassessable shares of Common Stock (as such shares shall then be constituted) obtained by dividing the aggregate principal amount of the Notes or portion thereof surrendered for conversion by the Conversion Price in effect at such time rounded to the nearest 1/100,000^th of a share (with 0.000005 being rolled upward) as such amount shall be certified by the Company as provided in an Officers’ Certificate, by following the procedures specified in Section 14.2. A Note (or portion thereof) in respect of which a holder is exercising its option to require repurchase upon a change of control pursuant to Section 3.5 of this Indenture, may only be converted if such holder withdraws its election to exercise said redemption option in accordance with the terms of this Indenture. A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder has converted such holder’s Notes to Common Stock and only to the extent such Notes are deemed to have been converted to Common Stock under this Article XIV.

(b) In the event that the Company does not amend its Articles of Incorporation on or before May 27, 2003 to increase the number of authorized shares of Common Stock to an amount sufficient to cover the conversion of the Notes and the existing notes due in 2008, the Company will, at the request of any Noteholder providing notice to the Company in a manner consistent with Section 16.4, purchase such Noteholder’s Notes in cash at a price equal to 125% of the principal amount of such Noteholder Notes plus accrued, but unpaid interest. The right of a Noteholder to request that the Company purchase such Noteholder’s Notes pursuant to this Section 14.1(b) shall terminate upon the amendment of the Company’s Articles of Incorporation to increase the number of authorized shares of Common Stock to an amount sufficient to cover the conversion of the Notes and the existing notes due in 2008.

(c) In the event a Noteholder desires to convert all, or any portion, of its Notes into shares of Common Stock (or other securities into which the Notes are then convertible) and the Company does not have authorized a sufficient number of shares of Common Stock (or other securities into which the Notes are then convertible) for such conversion, then in lieu of delivering shares of Common Stock (or other securities into which the Notes are then convertible) upon conversion pursuant to 14.1(a) of that portion of such holder’s Notes for which there is an insufficient number of shares of Common Stock (or other securities into which the Notes are then convertible) (the “Cash Equivalent Notes”), the Company shall pay to the holder converting the Cash Equivalent Notes who properly exercises the conversion privilege, as set forth in Section 14.2, an amount, as calculated by the Company and certified to the Trustee in an Officers’ Certificate of the Company, in cash equal to the Market Cash Conversion Price of the shares of Common Stock into which such Cash Equivalent Notes are then convertible.

(d) In the event that the Company directs the Trustee to pay cash upon any conversion in lieu of delivering shares of Common Stock or any other securities, as the case may be, the Company shall deliver to the Trustee written notice of such direction not later than the close of business on the first Trading Day after the date of receipt by the Trustee of the notice of conversion delivered by such holder pursuant to Section 14.2, and the Trustee shall notify by facsimile the contact person specified in the holder’s conversion notice of such election by the Company to such holder. In such event, notwithstanding any other provisions in this Article XIV, in lieu of delivering Common Stock upon conversion of such Notes surrendered in accordance with Section 14.2, the Company shall pay or direct the Trustee to pay the holder surrendering such securities an amount in cash equal to the Market Cash Conversion Price of the shares of Common Stock, plus any cash and other property theretofore apportioned to such shares of Common Stock in accordance with Section 14.2. Prior to or concurrently with such cash payment, the Company will provide the Trustee with an Officers’ Certificate setting forth the Market Cash Conversion Price and will deposit with the paying agent the cash so payable. The Trustee shall have no obligation or liability with respect to the calculation of the Market Cash Conversion Price.

(e) In the event that a Noteholder desires to convert all or any portion of its Notes into shares of Common Stock prior to October 15, 2005, the Company will pay such Noteholder an amount equal to the interest that would have been otherwise earned on such Notes between the date of such conversion and October 15, 2005 discounted to present value utilizing a rate of 6.25% with simple interest over a 360 day year. In the event that a Noteholder elects to convert prior to October 15, 2005 and the Company is required to pay interest pursuant to this Section 14.1(e), the Company may, in its sole discretion, elect to make such interest payment in cash or in shares of Common Stock based on 90% of the average Closing Prices of the Common Stock for the five Trading Days immediately preceding the conversion date. Prior to or concurrently with such payment, the Company will provide the Trustee with an Officers’ Certificate setting forth the calculation of the payment required by this Section 14.1(e). The Trustee shall have no obligation or liability with respect to the calculation of the payments required by this Section 14.1(e).

Section 14.2 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 interest in the

Global Note, the beneficial holder must complete the appropriate instruction form for conversion pursuant to the Depository’s book-entry conversion program and follow the other procedures set forth in such program.

As promptly as practicable after satisfaction of the requirements for conversion set forth above, subject to Section 14.1(c) and in 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 in book-entry form the number of full shares issuable upon the conversion of such Note or portion thereof in the name of such holder in compliance with the Depository’s book-entry conversion program and with the provisions of this Article XIV and shall issue 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 14.4.

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 14.2 have been satisfied as to such Note (or portion thereof), and, subject to Section 14.1(c), the person in whose name any 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.

Any unpaid interest on any Note or portion thereof as of the date such Note or portion thereof is surrendered for conversion shall (unless such Note or portion thereof being converted shall have been called for redemption on a redemption date during the period from the close of business on or after any record date for the payment of interest to the close of business on the business day following the corresponding interest payment date) be paid in cash to the former holder of such Note or portion thereof on the next succeeding interest payment date.

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 14.3 MANDATORY CONVERSION. The Notes shall be automatically converted into Common Stock on the first date (the “Mandatory Conversion Date”) on or after the 15th Trading Day following October 15, 2005, on which: (i) the average of the Closing Price (as defined in Section 14.6(g)) of the Common Stock on 15 consecutive preceding Trading Days is equal to or greater than 110% of the Conversion Price and (ii) the Company has sufficient shares of Common Stock (or other securities into which the Notes are then convertible) authorized to execute the Mandatory Conversion (as defined below). The Notes shall be converted into that number of fully paid and nonassessable shares of Common Stock (or other securities into which the Notes are then convertible) obtained by dividing the aggregate principal amount of the Notes by the Conversion Price in effect at such time rounded to the nearest 1/100,000^th of a share (with 0.000005 being rolled upward) (the “Mandatory Conversion”).

The Company will monitor the Closing Price of the Common Stock. Upon the occurrence of Mandatory Conversion, the Company shall complete the appropriate instruction form for conversion pursuant to the Depository’s book-entry conversion program and follow the

procedures set forth in such program. Any interest on the Notes accrued as of the Mandatory Conversion Date shall be paid in cash to the former holders of such Notes on the next succeeding interest payment date. After the Mandatory Conversion, the Notes will no longer represent Indebtedness of the Company, will no longer accrue interest or require the Company to make any payment of principal, and the Company’s obligations to make any further payments with respect to the Notes will terminate (except for under this Section 14.3). The Company will cause to be issued in book-entry form shares of Common Stock sufficient to effect the Mandatory Conversion and shall issue 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 14.4. The shares of Common Stock issued as a result of the Mandatory Conversion shall be credited through the Depository’s book-entry conversion program to the respective account of each Noteholder as of the Mandatory Conversion Date.

Section 14.4 CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES. No fractional shares of Common Stock or scrip representing fractional shares shall be issued upon conversion of Notes. Subject to Section 14.1(c), (i) if more than one Note shall be surrendered for conversion at one time by the same holder, the number of fully paid and nonassessable shares of Common Stock issuable upon conversion of a Note shall be determined by dividing the aggregate principal amount of such Notes or portion thereof surrendered for conversion by the Conversion Price and (ii) the aggregate number of shares of Common Stock issuable upon conversion shall be rounded to the nearest 1/100,000th of a share (with .0000005 being rolled upward). If any fractional share of stock 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. The current market value of a share of Common Stock shall be determined by multiplying the fractional share by the Closing Price on the Trading Day immediately preceding the Mandatory Conversion Date or the date, pursuant to Section 14.2, on which the Notes (or specified portions thereof) are deemed to have been converted.

Section 14.5 CONVERSION PRICE. The conversion price of the Notes (the “Conversion Price”) shall be $1.75 per share of Common Stock, subject to adjustment as provided in this Article XIV.

Section 14.6 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 (i) pay a dividend or make a distribution on its outstanding Common Stock in shares of its Common Stock, (ii) subdivide or split its outstanding Common Stock into a greater number of shares, (iii) combine its outstanding Common Stock into a smaller number of shares or (iv) issue any shares of Capital Stock by reclassification of its Common Stock, the conversion price in effect immediately prior thereto shall be adjusted so that the holder of any Notes thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock of the Company which such holder would have owned or have been entitled to receive after the occurrence of any of the events described above had such Notes been surrendered for conversion immediately prior to the occurrence of such event or the record date therefor, whichever is earlier. An adjustment made pursuant to this subsection (a) shall become effective immediately after the close of business on the record date for determination of shareholders entitled to receive such dividend or distribution in the case of a

dividend or distribution (except as provided in Section 14.6(j)) and shall become effective immediately after the close of business on the effective date in the case of a subdivision, split, combination or reclassification. Any shares of Common Stock issuable in payment of a dividend shall be deemed to have been issued immediately prior to the close of business on the record date for such dividend for purposes of calculating the number of outstanding shares of Common Stock under Sections 14.6(b) and (c).

(b) In case the Company shall issue rights, options or warrants to all holders of its outstanding shares of Common Stock 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 14.6(g)) on the Record Date fixed for determination of shareholders 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 the Record Date by a fraction the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the Record Date plus the number of shares that the aggregate offering price of the total number of shares so offered would purchase at such Current Market Price, and the denominator of which shall be the number of shares of Common Stock outstanding on 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 shareholders entitled to receive such rights, options or warrants. To the extent that shares of Common Stock are not delivered after the expiration or termination of such rights, options or warrants, the Conversion Price shall be readjusted to the Conversion Price that would then be in effect had the adjustments made upon the issuance of such rights, options 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, options or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such date fixed for the determination of shareholders entitled to receive such rights, options or warrants had not been fixed. In determining whether any rights, options 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, options or warrants, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which 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 14.6(a) applies) or evidences of its indebtedness or assets (including securities, but excluding any rights, options or warrants referred to in Section 14.6(b), and excluding any dividend or distribution (x) in connection with the liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, (y) exclusively in cash or (z) referred to in Section 14.6(a) (any of the foregoing hereinafter in this Section 14.6(d) called 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 14.6(g)) with respect to such distribution by a fraction of which the numerator shall be the Current Market Price (determined as provided in Section 14.6(g)) 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 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 the amount of Securities such holder would have received had such holder converted each Note on such 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 that 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 14.6(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 used in computing the Current Market Price pursuant to Section 14.6(g) to the extent possible.

Notwithstanding the foregoing provisions of this Section 14.6(d), no adjustment shall be made hereunder for any distribution of Securities if the Company makes proper provision so that each Noteholder who converts a Note (or any portion thereof) after the date fixed for determination of shareholders entitled to receive such distribution shall be entitled to receive upon such conversion, in addition to the shares of Common Stock issuable upon such conversion, the amount and kind of Securities that such holder would have been entitled to receive if such holder had, immediately prior to such determination date, converted such Note into Common Stock; provided that, with respect to any Securities that are convertible, exchangeable or exercisable, the foregoing provision shall only apply to the extent (and so long as) the Securities receivable upon conversion of such Note would be convertible, exchangeable or exercisable, as applicable, without any loss of rights or privileges for a period of at least 60 days following conversion of such Note.

Rights, options or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to 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 (the “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 not be deemed distributed for purposes of this Section 14.6(d) (and no adjustment to the Conversion Price under Section 14.6(d) shall be required) until the

occurrence of the earliest Trigger Event. In addition, in the event of any distribution of rights, options or warrants, or any Trigger Event with respect thereto, that shall have resulted in an adjustment to the Conversion Price under this Section 14.6(d), (1) in the case of any such rights, options or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with respect to such rights, options 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 by any holder thereof, the Conversion Price shall be readjusted as if such issuance had not occurred.

For purposes of this Section 14.6(d) and Sections 14.6(a) and (b), any dividend or distribution to which this Section 14.6(d) is applicable that also includes shares of Common Stock, or rights, options or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of Capital Stock other than such shares of Common Stock or rights, options or warrants (and any Conversion Price reduction required by this Section 14.6(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, options or warrants (and any further Conversion Price reduction required by Sections 14.6(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 shareholders entitled to receive such dividend or other distribution” and “the date fixed for such determination” within the meaning of Sections 14.6(a) and (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 14.6(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 14.7 applies or as part of a distribution referred to in Section 14.6(d) for which an adjustment to the Conversion Price is provided therein) 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 12 months preceding the date of payment of such distribution, and in respect of which no adjustment pursuant to this Section 14.6(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 12 months preceding the date of payment of such distribution, and in respect of which no adjustment pursuant to Section 14.6(f) has been made, exceeds 20.0% of the product of the Current Market Price (determined as provided in Section 14.6(g)) on the 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, unless the Company elects to reserve such cash for distribution to the holders of the Notes upon the conversion of the Notes so that any such holder converting Notes shall receive upon such

conversion, in addition to the shares of Common Stock to that such holder is entitled, the 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, 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 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 20.0% 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 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 the amount of cash such holder would have received had such holder converted each Note on the 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 that would then be in effect if such dividend or distribution had not been declared.

(f) In case a tender offer made by the Company or any of its Subsidiaries 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 shareholders (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 offer, by the Company or any of its Subsidiaries for all or any portion of the Common Stock expiring within the 12 months preceding the expiration of such tender offer, and in respect of which no adjustment pursuant to Section 14.6(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 12 months preceding the expiration of such tender offer, and in respect of which no adjustment pursuant to Section 14.6(e) has been made, exceeds 20.0% of the product of the Current Market Price (determined as provided in Section 14.6(g)) 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 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 shareholders 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 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 that would then be in effect if such tender offer had not been made.

(g) For purposes of this Section 14.6, the following terms shall have the meaning indicated:

(i) “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 New York Stock Exchange, or, if such security is not listed or admitted to trading on such 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.

(ii) “Current Market Price” shall mean the average of the daily Closing Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to the date in question; provided that (1) if the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution or Change of Control requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 14.6(a), (b), (c), (d), (e) or (f) occurs during such ten 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, distribution or Change of Control requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 14.6(a), (b), (c), (d), (e) or (f) 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 adjusted as a result of such other event and (3) if the “ex” date for the issuance, distribution or Change of Control 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 14.6(d) or (f), 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 Section 14.6(f), 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 that if the “ex” date for any event (other than the tender or exchange offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 14.6(a), (b), (c), (d), (e) or (f) 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 of such offer. Notwithstanding the foregoing, whenever successive adjustments to the Conversion Price are called for pursuant to this Section 14.6, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 14.6 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

(iii) “fair market value” shall mean the amount that a willing buyer would pay a willing seller in an arm’s-length transaction.

(iv) “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 property, the date fixed for determination of shareholders 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).

(h) The Company may make such reductions in the Conversion Price, in addition to those required by Sections 14.6(a), (b), (c), (d), (e) and (f), 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 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 all holders of record of the Notes a notice of the reduction at least 15 days prior to the date the reduced Conversion Price takes effect, and such notice shall state the reduced Conversion Price and the period it shall be in effect.

(i) 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 that any adjustments that by reason of this Section 14.6(i) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article XIV shall be made by the Company and shall be made to the nearest 1/100,000 (with 0.0000005 being rolled upward).

No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest.

No adjustment need be made for a change in the par value, or to or from no par value, of the Common Stock.

To the extent the Notes become convertible into cash, assets, property or securities (other than Common Stock of the Company), no adjustment need be made thereafter as to the cash, assets, property or such securities (except as such securities may otherwise by their terms provide), and interest shall not accrue on such cash.

(j) 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 to the holder of each Note at his last address appearing on the Note register provided for in Section 2.5, within 20 days after execution thereof. Failure to deliver such notice shall not effect the legality or validity of any such adjustment.

(k) In any case in which this Section 14.6 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 14.4.

Section 14.7 EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE. If any of the following events occur, namely (i) any reclassification or change of outstanding shares of Common Stock (other than a change in par value, or to or from no par value, 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 (determined on a consolidated basis) 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 the Notes 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 reclassification, change, consolidation, merger, combination, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such reclassification, change, consolidation, merger, combination, 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 14.7 the kind and amount of securities, cash or other property receivable upon such reclassification, change, consolidation, merger, combination, 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 that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article XIV.

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, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

The above provisions of this Section 14.7 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances.

Section 14.8 TAXES ON SHARES ISSUED. The issuance of stock certificates on conversions of Notes shall be made without charge to the converting Noteholder for any

transfer or similar tax in respect of the issue thereof. The Company shall not, however, be required to pay any tax that may be payable in respect of any transfer involved in the issue and delivery of 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 issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 14.9 RESERVATION OF SHARES; SHARES TO BE FULLY PAID; LISTING OF COMMON STOCK. Subject to Section 14.1(c) 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 that 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 shall take all corporate action that 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 that may be issued upon conversion of Notes shall, upon issuance, be fully paid and nonassessable by the Company and free from all taxes, liens and charges with respect to the issuance thereof.

Section 14.10 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 that may require any adjustment of the Conversion Price or notice thereof, or with respect to the nature, accuracy 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, that 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 or actions or omissions by the Company in connection with this Article XIV. Subject to the provisions of Section 7.1, 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 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 XIV. Without limiting the generality of the foregoing, neither the Trustee nor any conversion agent shall be under any responsibility to determine whether a supplemental indenture under Section 14.7 hereof need to be entered into or the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.7 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 14.7 or to any adjustment to be made with respect thereto, and 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 14.11 NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS. In case:

(a) the Company makes any distribution or dividend that would require an adjustment in the Conversion Price pursuant to Section 14.6; or

(b) the Company takes any action that would require a supplemental indenture pursuant to Section 14.7; or

(c) 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, as promptly as possible but in any event at least 15 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record date is to be taken for the purpose of such dividend, distribution, rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights, options or warrants are to be determined or (y) the date on which such reclassification, change, consolidation, merger, sale, conveyance, 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 record of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, change, consolidation, merger, sale, conveyance, transfer, dissolution, liquidation or winding-up. Neither the failure to give such notice nor any defect therein shall affect the legality or validity of the proceedings referenced in clauses (a) through (c) of this Section 14.11.

Section 14.12 SUPPLEMENTAL INDENTURE PRIOR TO ISSUANCE OF NOTES IN DEFINITIVE FORM. If the Company is required by this Indenture or chooses to issue Notes in definitive form, then the Company 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 of such supplemental indenture is then required to so comply) stating procedures under this Article XIV for the mandatory and optional conversion of definitive Notes into Common Stock.

ARTICLE XV

SUBORDINATION

Section 15.1 AGREEMENT TO SUBORDINATE. The Company agrees, and each Noteholder by accepting a Note agrees, that the indebtedness evidenced by the Notes is subordinated in right of payment, to the extent and in the manner provided in this Article XV, to the prior payment in full of all Senior Indebtedness and that the subordination is for the benefit of the holders of Senior Indebtedness.

Section 15.2 CERTAIN DEFINITIONS. For purposes of this Article XV, the following terms shall have the meaning indicated:

(1) “Representative” shall mean a duly authorized indenture trustee or other trustee, agent or representative for any Senior Indebtedness.

(2) “Senior Indebtedness” with respect to the Notes means the principal of, premium, if any, and interest on, and any fees, costs, expenses and any other amounts (including indemnity payments) related to the following, whether outstanding on the date hereof or hereafter incurred or created: (a) indebtedness, matured or unmatured, whether or not contingent, of the Company for money borrowed evidenced by notes or other written obligations, (b) any interest rate contract, interest rate swap agreement or other similar agreement or arrangement designed to protect the Company or any of its Subsidiaries against fluctuations in interest rates, (c) indebtedness, matured or unmatured, whether or not contingent, of the Company evidenced by notes, debentures, bonds or similar instruments or letters of credit (or reimbursement agreements in respect thereof), (d) obligations of the Company as lessee under capitalized leases and under leases of property made as part of any sale and leaseback transactions, (e) indebtedness of others of any of the kinds described in the preceding clauses (a) through (d) assumed or guaranteed by the Company and (f) renewals, extensions, modifications, amendments, and refundings of, and indebtedness and obligations of a successor person issued in exchange for or in replacement of, indebtedness or obligations of the kinds described in the preceding clauses (a) through (f), unless the agreement pursuant to which any such indebtedness described in clauses (a) through (f) is created, issued, assumed or guaranteed expressly provides that such indebtedness is not senior or superior in right of payment to the Notes; provided that the following shall not constitute Senior Indebtedness: (i) any indebtedness or obligation of the Company in respect of the Notes, (ii) any indebtedness of the Company to any of its Subsidiaries or other Affiliates; (iii) any indebtedness that is subordinated or junior in any respect to any other indebtedness of the Company other than Senior Indebtedness; (iv) any indebtedness incurred for the purchase of goods or materials in the ordinary course of business and (v) any indebtedness or obligation of the Company in respect of the 6-1/4% Convertible Subordinated Notes Due 2003.

For the purposes of this Indenture, Senior Indebtedness shall not be deemed to have been paid in full until the holders of the Senior Indebtedness shall have indefeasibly received payment in full in cash of all Senior Indebtedness; provided that if any holder of Senior Indebtedness agrees to accept payment in full of such Senior Indebtedness for consideration other than cash, such holder shall be deemed to have indefeasibly received payment in full of such Senior Indebtedness. The provisions of this Article XV shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Senior Indebtedness is rescinded or must otherwise be returned by any holder of Senior Indebtedness upon the insolvency, bankruptcy or organization of the Company or otherwise, all as though such payment had not been made.

A distribution may consist of cash, securities or other property, by set-off or otherwise.

Section 15.3 LIQUIDATION; DISSOLUTION; BANKRUPTCY. Upon any distribution to creditors of the Company in a liquidation or dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, in an assignment for the benefit of creditors or any marshalling of the Company’s assets and liabilities, (a) holders of all Senior Indebtedness shall first be entitled to receive payment in full of all amounts due or to become due thereon before Noteholders shall be entitled to receive any payment with respect to the principal of, premium, if any, or interest on the Notes (except that Noteholders may receive securities that are subordinated to at least the same extent as the Notes to Senior Indebtedness and any securities issued in exchange for Senior Indebtedness) and (b) until all Senior Indebtedness (as provided in clause (a) above) is paid in full, any distribution to which Noteholders would be entitled but for this Article shall be made to holders of Senior Indebtedness (except that Noteholders may receive securities that are subordinated to at least the same extent as the Notes to (x) Senior Indebtedness and (y) any securities issued in exchange for Senior Indebtedness), as their interests may appear.

Section 15.4 DEFAULT ON SENIOR INDEBTEDNESS. The Company may not make any payment upon or in respect of the Notes (except in such subordinated securities) and may not acquire from the Trustee or any Noteholder any Note for cash or property (other than securities that are subordinated to at least the same extent as the Note to (i) Senior Indebtedness and (ii) any securities issued in exchange for Senior Indebtedness) until all Senior Indebtedness has been paid in full if:

(a) a default in the payment of the principal of, premium, if any, or interest on Senior Indebtedness occurs and is continuing beyond any applicable period of grace (a “Payment Default”); or

(b) a default, other than a Payment Default on Senior Indebtedness occurs and is continuing that permits holders of the Senior Indebtedness as to which such default relates to accelerate its maturity (a “Nonpayment Default”) and the Trustee receives a notice of the default (a “Payment Blockage Notice”) from the Representative or Representatives of holders of at least a majority in principal amount of Senior Indebtedness then outstanding. No Nonpayment Default that existed or was continuing on the date of delivery of any such Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice unless such default shall have been cured or waived for a period of not less than 180 days. No new period of payment blockage may be commenced within 360 days after the receipt by the Trustee of any prior Payment Blockage Notice.

The Company, with notice and evidence of the occurrence of (c) or (d) provided to the Trustee, may and shall resume payments on and distributions in respect of the Notes and may acquire them upon the earlier of:

(c) in the case of a Payment Default, upon the date on which the default is cured or waived, or

(d) in the case of a default other than a NonPayment Default: 179 days after the date on which the applicable Payment Blockage Notice is received, unless the maturity of

such Senior Indebtedness has been accelerated, if this Article XV otherwise permits the payment, distribution or acquisition at the time of such payment or acquisition.

Section 15.5 WHEN DISTRIBUTION MUST BE PAID OVER. In the event that the Trustee (or paying agent if other than the Trustee) or any Noteholder receives any payment of principal or interest with respect to the Notes at a time when such payment is prohibited by Section 15.3 or 15.4 hereof, such payment shall be held by the Trustee (or paying agent if other than the Trustee) or such Noteholder, in trust for the benefit of, and immediately shall be paid over and delivered, upon written request, to, the holders of Senior Indebtedness as their interests may appear or their Representative under the indenture or other agreement (if any) pursuant to which Senior Indebtedness may have been issued, as their respective interests may appear, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness.

With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform only such obligations on the part of the Trustee as are specifically set forth in this Article XV, 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 shall not be liable to any such holders if the Trustee shall pay over or distribute to or on behalf of Noteholders or the Company or any other person money or assets to which any holders of Senior Indebtedness shall be entitled by virtue of this Article XV, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee.

Section 15.6 NOTICE BY COMPANY. The Company shall promptly notify the Trustee and the paying agent in writing of any facts known to the Company that would cause a payment of any principal or interest with respect to the Notes to violate this Article XV, but failure to give such notice shall not affect the subordination of the Notes to the Senior Indebtedness as provided in this Article XV.

Section 15.7 SUBROGATION. Until all Senior Indebtedness is paid in full and until the Notes are paid in full, Noteholders shall be subrogated (equally and ratably with all other indebtedness pari passu with the Notes) to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness to the extent that distributions otherwise payable to the Noteholders have been applied to the payment of Senior Indebtedness. A distribution made under this Article XV to holders of Senior Indebtedness that otherwise would have been made to Noteholders is not, as between the Company and Noteholders, a payment by the Company on the Notes.

Section 15.8 RELATIVE RIGHTS. This Article XV defines the relative rights of Noteholders and holders of Senior Indebtedness. Nothing in this Indenture shall:

(a) impair, as between the Company and the Noteholders, the obligation of the Company, which is absolute and unconditional, to pay principal of, premium, if any, and interest on the Notes in accordance with their terms;

(b) affect the relative rights of Noteholders and creditors of the Company other than their rights in relation to holders of Senior Indebtedness; or

(c) prevent the Trustee or any Noteholder from exercising its available remedies upon a default or Event of Default, subject to the rights of holders and owners of Senior Indebtedness to receive distributions and payments otherwise payable to Noteholders.

If the Company fails because of this Article XV to pay principal of, premium, if any, or interest on a Note on the due date, the failure is still a default or Event of Default.

Section 15.9 SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY. No right of any holder of Senior Indebtedness to enforce the subordination of the indebtedness evidenced by the Notes shall be impaired by any act or failure to act by the Company or any holder of Notes or by the failure of the Company or any holder of Notes to comply with this Indenture.

Section 15.10 DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness, the distribution may be made and the notice given to their Representative.

Upon any payment or distribution of assets of the Company referred to in this Article XV, the Trustee and the Noteholders shall be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such Representative or of the liquidating trustee or agent or other person making any distribution to the Trustee or to the Noteholders 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 XV.

Section 15.11 RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding the provisions of this Article XV or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the paying agent may continue to make payments on the Notes, unless the Trustee shall have received at its Corporate Trust Office at least three Business Days prior to the date of such payment written notice of facts that would cause the payment of any principal, premium, if any, and interest with respect to the Notes to violate this Article XV. Only the Company or a Representative may give the notice. Nothing in this Article XV shall impair the claims of, or payments to, the Trustee under or pursuant to Section 7.6 hereof.

The Trustee shall be entitled to rely on the delivery to it of a written notice by a person representing such person to be a holder of Senior Indebtedness (or a trustee or agent on behalf of such holder) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee or agent on behalf of any such holder). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article XV, 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 XV, and if such evidence is not furnished, the Trustee may defer any payment which it may be required to make for the benefit of such person pursuant to the terms of this Indenture pending judicial determination as to the rights of such person to receive such payment.

The Trustee in its individual or any other capacity may hold Senior Indebtedness with the same rights it would have if it were not Trustee. Any paying agent, any authenticating agent, any conversion agent, any Note registrar and their successors may do the same with like rights.

Section 15.12 AUTHORIZATION TO EFFECT SUBORDINATION. Each holder of a Note by the holder’s acceptance thereof authorizes and directs the Trustee on the holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article XV and appoints the Trustee to act as the holder’s attorney-in-fact for any and all such purposes. Without limiting the foregoing, each Representative is hereby irrevocably authorized and empowered (in its own name or in the name of the Noteholders or the Trustee or otherwise), but shall have no obligation, to demand, sue for, collect and receive every payment or distribution referred to in Section 15.3 above and give acquittance therefor and to file claims and proofs of claim and take such other action as it may deem necessary or advisable for the exercise or enforcement of any of the rights or interests of the holders or owners of the Senior Indebtedness hereunder; provided that for purposes of this Section 15.12 holders or owners of Senior Indebtedness may act only through such Representative.

Section 15.13 CONVERSIONS NOT DEEMED PAYMENT. For the purposes of this Article XV only, the issuance and delivery of Common Stock upon conversion of the Notes in accordance with Article XIV shall not be deemed to constitute a payment or distribution on account of the principal of or interest on the Notes or on account of the purchase or other acquisition of Notes. 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, the right, which is absolute and unconditional, of the holder of any Note to convert such Note in accordance with Article XIV.

Section 15.14 AMENDMENTS. The provisions of this Article XV shall not be amended or modified without the written consent of the holders of Senior Indebtedness.

[FORM OF REVERSE OF GLOBAL NOTE]

PENN TREATY AMERICAN CORPORATION

6-1/4% Convertible Subordinated Notes Due 2008

This Global Note is one of a duly authorized issue of Notes of the Company, designated as its 6-1/4% Convertible Subordinated Notes Due 2008 (herein called the “Notes”), limited to the aggregate principal amount of $ all issued or to be issued under and pursuant to an Indenture dated as of February , 2003 (the “Indenture”), between the Company and Wells Fargo Bank Minnesota, N.A., as trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a complete description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Notes. Each Note is subject to, and qualified by, all such terms as set forth in the Indenture certain of which are summarized hereon and each holder of a Note is referred to the corresponding provisions of the Indenture for a complete statement of such terms. To the extent that there is any inconsistency between the summary provisions set forth in the Notes and the Indenture, the provisions of the Indenture shall govern. Capitalized terms used but not defined in this Global Note shall have the meanings ascribed to them in the Indenture.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, premium, if any, and accrued interest on all Notes may be declared, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The payment of principal of, premium, if any, and interest on the Notes will, to the extent set forth in the Indenture, be subordinated in right of payment to the prior payment in full of all Senior Indebtedness (as defined in the Indenture). Upon any distribution to creditors of the Company in a liquidation or dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding related to the Company or its property, in an assignment for the benefit of creditors or any marshalling of the Company’s assets and liabilities, the holders of all Senior Indebtedness will first be entitled to receive payment in full of all amounts due or to become due thereon before the holders of the Notes will be entitled to receive any payment in respect of the principal of, premium, if any, or interest on the Notes (except that holders of Notes may receive securities that are subordinated at least to the same extent as the Notes to Senior Indebtedness and any securities issued in exchange for Senior Indebtedness).

The Company also may not make any payment upon or in respect of the Notes (except in such subordinated securities) and may not acquire from the Trustee or the holder of any Note for cash or property (other than securities subordinated to at least the same extent as the Note to (i) Senior Indebtedness and (ii) any securities issued in exchange for Senior Indebtedness) until all Senior Indebtedness has been paid in full if (a) a default in the payment of the principal of, premium, if any, or interest on Senior Indebtedness occurs and is continuing beyond any applicable period of grace or (b) any other default occurs and is continuing with respect to Senior Indebtedness that permits holders of the Senior Indebtedness as to which such default relates to accelerate its maturity and the Trustee receives a notice of such default (a

A-5

“Payment Blockage Notice”) from the representative or representatives of holders of at least a majority in principal amount of Senior Indebtedness then outstanding. Payments on the Notes may and shall be resumed (i) in the case of a Payment Default, upon the date on which such default is cured or waived, or (ii) in the case of a Nonpayment Default, 179 days after the date on which the applicable Payment Blockage Notice is received, unless the maturity of any Senior Indebtedness has been accelerated. No new period of payment blockage may be commenced within 360 days after the receipt by the Trustee of any prior Payment Blockage Notice. No default, other than a Nonpayment Default, that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice unless such default shall have been cured or waived for a period of not less than 180 days.

In the event that the Trustee (or paying agent if other than the Trustee) or any holder of the Notes receives any payment of principal or interest with respect to the Notes at a time when such payment is prohibited under the Indenture, such payment shall be held in trust for the benefit of, and immediately shall be paid over and delivered to, the holders of Senior Indebtedness or their representative as their respective interests may appear. After all Senior Indebtedness is paid in full and until the Notes are paid in full, the holders of the Notes shall be subrogated (equally and ratably with all other Indebtedness pari passu with the Notes) to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness to the extent that distributions otherwise payable to the holders of the Notes have been applied to the payment of Senior Indebtedness.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Notes; provided that no such supplemental indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or extend the time of payment of interest thereon, or reduce the principal amount thereof or premium, if any, thereon, or reduce any amount payable on redemption thereof, alter the obligation of the Company to repurchase the Notes at the option of the holders upon the occurrence of a Change of Control, or impair or affect the right of any Noteholder to institute suit for the payment thereof, or make the principal thereof or interest or premium, if any, thereon payable in any coin or currency other than that provided in the Notes, modify the subordination provisions in a manner adverse to the holders of the Notes, or impair the right to convert the Notes into Common Stock subject to the terms set forth in the Indenture without the consent of the holder of each Note so affected or (ii) reduce the aforesaid percentage of Notes, the holders of which are required to consent to any such supplemental indenture, without the consent of the holders of all Notes then outstanding. The Company and the Trustee may amend or supplement the Indenture without notice to or consent of any holder of Notes in certain events specified in the Indenture. It is also provided in the Indenture that, prior to any declaration accelerating the maturity of the Notes, the holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the holders of all of the Notes waive any past default or Event of Default under the Indenture and its consequences except a default in the payment of interest or any premium on or the principal of any of the Notes, a failure by the Company to convert any Notes into Common Stock of the

A-6

Company, unless otherwise excused pursuant to the terms of the Indenture, or a default in respect of a covenant or provision of the Indenture that under Article X thereof cannot be modified or amended without the consent of the holders of all Notes then outstanding. Any such consent or waiver by the holder of this Global Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Global Note and any Notes that may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Global Note or such other Notes.

No reference herein to the Indenture and no provision of this Global Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Global Note at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

Interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months.

The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration or exchange of Notes, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations.

The Notes are not redeemable at the option of the Company prior to October 15, 2005. At any time on or after that date, the Notes may be redeemed at the Company’s option, upon notice as set forth in the Indenture, in whole at any time or in part from time to time, at the price of 100% of the principal amount, together with accrued interest to the date fixed for redemption; provided that if the date fixed for redemption is a date on or after the record date and on or before the next following Interest Payment Date, then the interest payable on such date shall be paid to the holder of record on the next preceding October 1 or April 1, respectively.

If a Change of Control (as defined in the Indenture) shall occur at any time, then each holder of Notes shall have the right to require that the Company repurchase such holder’s Notes in whole or in part in integral multiples of $1,000, at a purchase price in cash in an amount equal to 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to the repurchase date pursuant to an offer to be made by the Company and in accordance with the procedures set forth in the Indenture.

Subject to the provisions of the Indenture, the holder hereof has the right to convert the principal hereof or any portion of such principal that is $1,000 or an integral multiple thereof, into the Company’s Common Stock at any time following the earlier of (i) May 27, 2003 and (ii) the approval by our shareholders of an amendment to our Articles of Incorporation to increase the number of authorized shares of Common Stock to an amount sufficient to cover the conversion of the Notes, the conversion of the Company’s existing notes due in 2003 and 2008, the conversion of the Company’s convertible preferred stock issuable upon execution of the warrants granted to Centre Solutions (Bermuda) Limited and the exercise of outstanding options

granted pursuant to the Company’s stock option plan, until the close of business on October 14, 2008, subject to prior redemption or repurchase, or, as to all or any portion hereof called for redemption, prior to the close of business one business day before the date fixed for redemption (unless the Company shall default in payment due upon redemption thereof). The principal hereof or any portion of such principal that is $1,000 or an integral multiple thereof, is convertible into that number of fully paid and non-assessable shares of the Company’s Common Stock, as said shares shall be constituted at the date of conversion, obtained by dividing the principal amount of this Global Note or portion thereof to be converted by the conversion price of $1.75 per share or such conversion price as adjusted from time to time as provided in the Indenture, upon surrender of this Global Note to the Company at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, the City of New York, or at the option of such holder, the Corporate Trust Office of the Trustee, and, unless the shares issuable on conversion are to be issued in the same name as this Global Note, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or by his duly authorized attorney.

Except as described in the Indenture, no adjustment will be made on conversion of any Notes for interest accrued thereon or for dividends paid on any Common Stock issued. A Holder of Notes at the close of business on a record date will be entitled to receive the interest payable on such Notes on the corresponding interest payment date. Any unpaid interest on any Note or portion thereof as of the date such Note or portion thereof is surrendered for conversion shall (unless such Note or portion thereof being converted is called for redemption on a redemption date during the period from the close of business on or after any record date to the close of business on the business day following the corresponding interest payment date) be paid in cash to the former holder of such Note or portion thereof on the next succeeding interest payment date.

In the event that the Company does not amend its Articles of Incorporation on or before May 27, 2003 to increase the number of authorized shares of Common Stock to an amount sufficient to cover the conversion of the Notes and the existing notes due in 2008, the Company will, at the request of any holder, purchase such holder’s Notes at a price equal to 125% of the principal amount of such Notes. The right of a holder to request that the Company purchase such holder’s Notes pursuant to this Section 14.1(b) shall terminate upon the amendment of the Company’s Articles of Incorporation to increase the number of authorized Shares of Common Stock to an amount sufficient to cover the conversion of the Notes and the existing Notes due in 2008.

In the event a holder desires to convert all or any portion of its Notes into shares of Common Stock and the Company does not have authorized a sufficient number of shares of Common Stock for such conversion, in lieu of delivering shares of Common Stock (or other securities into which the Notes are then convertible) upon conversion of that portion of such holder’s Notes for which there is an insufficient number of shares of Common Stock (the “Cash Equivalent Notes”) pursuant to the provisions of the Indenture, the Company will pay to the holder converting the Cash Equivalent Notes who properly exercises the conversion privilege, as set forth in the Indenture, an amount in cash equal to the Market Cash Conversion Price (as defined in the Indenture) of the shares of Common Stock into which such Cash Equivalent Notes are then convertible.

A-8

On any date on or after the 15th business day following October 15, 2005, if: (i) the average of the closing price of the Common Stock on 15 consecutive business days is equal to or greater than 110% of the conversion price (as it may be adjusted in the Indenture) and (ii) the Company has sufficient shares of Common Stock (or other securities into which the Notes are then convertible) authorized to execute the Mandatory Conversion (as defined below), then the Notes shall be converted into that number of fully paid and nonassessable shares of Common Stock (or other securities into which the Notes are then convertible) obtained by dividing the aggregate principal amount of the Notes by the conversion price in effect at such time rounded to the nearest 1/100,000^th of a share (with 0.000005 being rolled upward) (the “Mandatory Conversion”). After the Mandatory Conversion, the Notes will no longer represent indebtedness of the Company and will no longer accrue interest or require the Company to make any payment of principal; and the Company’s obligations to make any further payments with respect to the Notes will terminate.

In the event that a Noteholder desires to convert all or any portion of its Notes into shares of Common Stock prior to October 15, 2005, the Company will pay such Noteholder an amount equal to the interest that would have been otherwise earned on such Notes between the date of such conversion and October 15, 2005 discounted to present value utilizing a rate of 6.25% with simple interest over a 360 day year. In the event that a Noteholder elects to convert prior to October 15, 2005 and the Company is required to pay interest pursuant to this Section 14.1(e), the Company may, in its sole discretion, elect to make such interest payment in cash or in shares of Common Stock based on 90% of the average Closing Prices of the Common Stock for the five Trading Days immediately preceding the conversion date.

The Company is not required to issue fractional shares of Common Stock upon conversion of Notes and, in lieu thereof, will pay a cash adjustment based upon the closing price of the Common Stock on the last business day prior to the date of conversion.

Upon due presentment for registration of transfer of this Global Note at the office or agency of the Company in the Borough of Manhattan, The City of New York, or at the option of the holder of this Global Note, at the Corporate Trust Office of the Trustee, a new Note or Notes of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange thereof, subject to the conditions and limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company, the Trustee, any authenticating agent, any paying agent, any conversion agent and any Note registrar may deem and treat the registered holder hereof as the absolute owner of this Global Note (whether or not this Global Note shall be overdue and notwithstanding any notation of ownership or other writing hereon made by anyone other than the Company or any Note registrar), for the purpose of receiving payment hereof, or on account hereof, for the conversion hereof and for all other purposes, and neither the Company nor the Trustee nor any other authenticating agent nor any paying agent nor any other conversion agent nor any Note registrar shall be affected by any notice to the contrary. All payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, satisfy and discharge liability for monies payable on this Global Note.

A-9

No recourse for the payment of the principal of or any premium or interest on this Global Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, shareholder, officer or director, as such, past, present or future, of the Company or of any Successor Company, either directly or through the Company or any Successor Company, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.
