An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.

The Securities shall be issued only in registered form without coupons and only in denominations of $1,000 of principal amount and any integral multiple of $1,000.

Section 2.3 Registrar, Paying Agent and Conversion Agent. Pursuant to Section 6.5, the Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (“Registrar”), an office or agency where Securities may be presented for redemption, repurchase or payment (“Paying Agent”), an office or agency where Securities may be presented for conversion (“Conversion Agent”) and an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. Pursuant to Section 6.5, the Company shall at all times maintain a Registrar, Paying Agent, Conversion Agent and an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, New York City. The Registrar shall keep a register of the Securities (the “Register”) and of their transfer and exchange.

The Company may have one or more co-registrars, one or more additional paying agents and one or more additional conversion agents. The term Paying Agent includes any additional paying agent, including any named pursuant to Section 6.5. The term Conversion Agent includes any additional conversion agent, including any named pursuant to Section 6.5.

The Company shall enter into an appropriate limited agency agreement with any Registrar, Paying Agent, Conversion Agent or co registrar (in each case, if such Registrar, agent or co registrar is a Person other than the Trustee). Each such agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 9.7. The Company or any Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent or co registrar and, if the Company fails to maintain a Conversion Agent, the Company shall act as such.

The Company hereby initially appoints the Trustee as Registrar, Paying Agent and Conversion Agent in connection with the Securities.

Section 2.4 Paying Agent to Hold Cash and Securities in Trust. Except as otherwise provided herein, prior to 10:00 a.m., New York City time, on each due date of payments in respect of any Security, the Company shall deposit with the Paying Agent, cash (in immediately available funds if deposited on the due date) or number of shares of Applicable Stock, as applicable, sufficient to make such payments when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all cash and Applicable Stock held by the Paying Agent for the making of payments in respect of the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company, a Subsidiary or an Affiliate of either of them acts as Paying Agent, it shall segregate the money and Applicable Stock held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all cash and Applicable Stock held by it to the Trustee, and to account for any funds and Applicable Stock disbursed by it, and the Trustee may at any time during the continuance of any such default, upon the written request to the Paying Agent, require such Paying Agent to forthwith pay to the Trustee all cash and Applicable Stock so held in trust. Upon doing so, the Paying Agent shall have no further liability for the cash or Applicable Stock.

Section 2.5 Holder 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. If the Trustee is not the Registrar, the Company shall cause to be furnished to the Trustee on or before each semiannual 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 may reasonably require of the names and addresses of Holders.

Section 2.6 Transfer and Exchange. (a) Subject to compliance with any applicable additional requirements contained in Section 2.12, when a Security is presented to the Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate, each in the form included in Exhibit A attached hereto and in form satisfactory to the Registrar and each duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange at an office or agency maintained for such purpose pursuant to Section 2.3, the Company shall execute, and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any transfer or exchange shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the transfer or exchange of the Securities from the Holder requesting such transfer or exchange.

Neither the Company, the Registrar nor the Trustee shall be required to exchange or register a transfer of (i) any Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed), or (ii) any Securities in respect of which a Purchase Notice or a Designated Event Purchase Notice has been given and not withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in the case of Securities to be repurchased in part, the portion thereof not to be repurchased).

All Securities issued upon any transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange.

(b) Any Registrar appointed pursuant to Section 2.3 shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities.

(c) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.7 Replacement Securities. If (a) any mutilated Security is surrendered to the Company, the Registrar or the Trustee, or (b) the Company, the Registrar and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the Registrar and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company, the Registrar or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a certificate number not contemporaneously outstanding.

-13-

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be repurchased by the Company pursuant to Article V, the Company in its discretion may, instead of issuing a new Security, pay, redeem or repurchase such Security, as the case may be.

Upon the issuance of any new Securities under this Section 2.7, the Company may require the payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee or the Registrar) connected therewith.

Every new Security issued pursuant to this Section 2.7 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

The provisions of this Section 2.7 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 2.8 Outstanding Securities; Determinations of Holders’ Action. Securities outstanding at any time are all the Securities authenticated by the Trustee, except for:

(a) those cancelled by it,

(b) those paid, redeemed or repurchased pursuant to Section 2.7, those delivered to it for cancellation, and

(c) those described in this Section 2.8 as not outstanding.

A Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security; provided, however, that in determining whether the Holders of the requisite principal amount of Securities have given or concurred in any request, demand, authorization, direction, notice, consent, waiver, or other Act hereunder, Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent, waiver or other Act, only Securities which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. Subject to the foregoing, only Securities outstanding at the time of such determination shall be considered in any such determination.

If a Security is replaced pursuant to Section 2.7, the replaced Security ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser unaware that such Security has been replaced.

-14-

If the Paying Agent holds, in accordance with the terms of this Indenture, prior to 10:00 a.m., New York City time, on a Designated Event Purchase Date or Stated Maturity, as the case may be, cash or securities, if permitted hereunder, sufficient to pay Securities payable on that date, then on such Designated Event Purchase Date or Stated Maturity, as the case may be, such Securities shall cease to be outstanding and interest (inclusive of Additional Interest, if any) on such Securities shall cease to accrue.

If a Security is converted in accordance with Article XII, then from and after the time of conversion on the date of conversion, such Security shall cease to be outstanding and interest (inclusive of Additional Interest, if any) on such Security shall cease to accrue.

Section 2.9 Temporary Securities. Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the Officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities.

If temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 2.3, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

Section 2.10 Cancellation. All Securities surrendered for payment, repurchase by the Company pursuant to Article V, conversion, redemption or registration of transfer or exchange shall, if surrendered to any person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. The Company may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article XII. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 2.10, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with the Trustee’s customary procedure.

Section 2.11 Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment (whether in cash or Applicable Stock) of principal of, Designated Event Purchase Price, and interest (inclusive of Additional Interest, if any) on, the

-15-

Security, for the purpose of receiving cash or Applicable Stock upon conversion and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

(x) to register the transfer of the Securities; or

Each Transfer Restricted Security shall have attached thereto a certificate (a “Transfer Certificate”) in substantially the form called for by footnote 2 to Exhibit A attached hereto.

(2) Upon any sale or transfer of a Transfer Restricted Security (x) after the expiration of the holding period applicable to sales of the Securities under Rule 144(k) of the Securities Act, (y) pursuant to Rule 144 or (z) pursuant to an effective registration statement under the Securities Act, any Registrar shall permit the Holder thereof to exchange such Restricted Security for an Unrestricted Security; provided, however, that the Holder of such Restricted Security shall, in connection with such exchange or transfer, comply with the other applicable provisions of this Section 2.12.

(c) Transfers to the Company. Nothing contained in this Indenture or in the Securities shall prohibit the sale or other transfer of any Securities to the Company or any of its Subsidiaries, which Securities shall thereupon be cancelled in accordance with Section 2.10.

unpaid interest (inclusive of Additional Interest, if any) to, but excluding, the Designated Event Purchase Date (collectively, the “Designated Event Purchase Price”). In the event that a Designated Event Purchase Date is a date that is after any Regular Record Date but on or before the corresponding Interest Payment Date, the Company shall be required to pay accrued and unpaid interest (inclusive of Additional Interest, if any) to the holder of the repurchased Security and not the Holder on the Regular Record Date.

(b) No later than 20 calendar days after the occurrence of a Designated Event, the Company shall mail a written notice of the Designated Event by first class mail to the Trustee (and the Paying Agent if the Trustee is not then acting as Paying Agent) and to each Holder at its address shown in the Register of the Registrar, and to beneficial owners as required by applicable law. The notice shall include a form of Designated Event Purchase Notice to be completed by the Holder and shall briefly state, as applicable:

(i) the date of such Designated Event and, briefly, the events causing such Designated Event;

(ii) the date by which the Designated Event Purchase Notice must be delivered to the Paying Agent in order for a Holder to exercise the purchase right pursuant to this Section 5.1;

(iii) the Designated Event Purchase Date;

(viii) that the Securities must be surrendered to the Paying Agent to collect payment;

(ix) that the Designated Event Purchase Price for any Security as to which a Designated Event Purchase Notice has been duly given and not withdrawn shall be paid promptly following the later of the Designated Event Purchase Date and the time of surrender of such Security as described in Section 5.1(b)(viii);

(x) the procedures the Holder must follow to exercise rights under this Section 5.1 and a brief description of such rights;

(xiv) the CUSIP number(s) of the Securities.

At the Company’s request, the Trustee shall give the notice of purchase right in the Company’s name and at the Company’s expense; provided, however, that the Company makes such request at least five Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such notice of purchase right must be given to the Holders in accordance with this Section 5.1(b); provided, further, that the text of the notice of purchase right shall be prepared by the Company.

Simultaneously with delivering the written notice pursuant to this Section 5.1(b), the Company shall publish a notice containing all information specified in such written notice in a newspaper of general circulation in New York, New York or publish such information on the Company’s website, or through such other public medium that reasonably could be expected to inform Holders of such information.

The Designated Event Purchase Notice delivered by a Holder shall state (i) the certificate number or numbers of the Security or Securities which the Holder shall deliver to be purchased, (ii) the portion of the Principal Amount of the Security which the Holder shall deliver to be purchased, which portion must be $1,000 or an integral multiple thereof, and (iii) that such Security shall be purchased pursuant to the terms and conditions specified in the Securities and this Indenture.

Delivery of a Security to the Paying Agent by physical delivery prior to, on or after the Designated Event Purchase Date (together with all necessary endorsements) at the offices of the Paying Agent is a condition to receipt by the Holder of the Designated Event Purchase Price therefor; provided, however, that such Designated Event Purchase Price shall be so paid pursuant to this Section 5.1 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Designated Event Purchase Notice, as determined by the Company.

The Company shall purchase from the Holder thereof, pursuant to this Section 5.1, a portion of a Security if the Principal Amount of such portion is $1,000 or an

Securities in respect of which a Designated Event Purchase Notice has been given by the Holder thereof may not be converted pursuant to Article XII on or after the date of the delivery of such Designated Event Purchase Notice unless such Designated Event Purchase Notice has first been validly withdrawn as specified in the following paragraph.

(b) A Designated Event Purchase Notice may be withdrawn by means of a written notice (which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form) of withdrawal delivered by the Holder to the Paying Agent at any time prior to the close of business on the Business Day immediately preceding the Designated Event Purchase Date, specifying (a) the Principal Amount of the Security or portion thereof (which must be a Principal Amount of $1,000 or an integral multiple of $1,000 in excess thereof) with respect to which such notice of withdrawal is being submitted, (b) the certificate numbers of the withdrawn Securities, and (c) the Principal Amount, if any, which remains subject to the Designated Event Purchase Notice.

Section 5.3 Deposit of Designated Event Purchase Price.

-21-

such Securities are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Designated Event Purchase Price upon delivery of such Securities).

The Company shall publicly announce the Principal Amount of Securities purchased as a result of such Designated Event on or as soon as practicable after the Designated Event Purchase Date by publishing a notice containing such information in a newspaper of general circulation in New York, New York or by publishing such information on the Company’s website, or through such other public medium that reasonably could be expected to inform Holders of such information.

Section 5.4 Securities Purchased in Part. Any Security that is to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and promptly after the Designated Event Purchase Date the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without charge, a new Security or Securities, of any authorized denomination or denominations as may be requested by such Holder, in aggregate Principal Amount equal to, and in exchange for, the portion of the Principal Amount of the Security so surrendered that is not purchased.

To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 5.3 exceeds the aggregate Designated Event Purchase Price of the Securities or portions thereof which the Company is obligated to purchase as of the Designated Event Purchase Date then, promptly after the Designated Event Purchase Date, the Paying Agent shall return any such excess to the Company.

If any fractional share of Common Stock otherwise would be issuable upon the payment of or provision for interest, the Company, at its option, may either make an adjustment therefore in cash at the current market value thereof to the Holder of the Securities or round the fractional shares up to the nearest whole share, provided that if such Holder holds more than one Security the number of full shares that shall be issuable upon the payment of or provision for interest shall be computed on the basis of the aggregate principal amount (and the aggregate interest amount payable thereon) of all of the Securities held by such Holder.

Section 6.2 SEC and Other Reports to the Trustee. (a) The Company shall ensure delivery to the Trustee within 15 calendar days after it files such annual and quarterly reports, information, documents and other reports with the SEC, copies of its annual report and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act in accordance with TIA Section 314(a). In the event the Company is at any time no longer subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, it shall continue to provide the Trustee with reports containing substantially the same information as would have been required to be filed with the SEC had the Company continued to have been subject to such reporting requirements. In such event, such reports shall be provided at the times the Company would have been required to provide reports had it continued to have been subject to such reporting requirements. The Company also shall comply with the other provisions of TIA Section 314(a). 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 conclusively on Officers’ Certificates). The Trustee shall have no duty or responsibility to review such reports, information or documents.

(b) The Company intends to file the reports referred to in paragraph (a) above in this Section 6.2 hereof with the SEC in electronic form pursuant to Regulation S-T of the SEC using the SEC’s Electronic Data Gathering, Analysis and Retrieval (“XXXXX”) system. The Company shall notify the Trustee in the manner prescribed herein of each such filing. The Trustee is hereby authorized and directed to access the XXXXX system for purposes of retrieving the reports so filed. Compliance with the foregoing shall constitute delivery by the Company of such reports to the Trustee in compliance with the provisions of TIA Section 314(a). The Trustee shall have no duty to search for or obtain any electronic or other filings that the Company makes with the SEC, regardless of whether such filings are periodic, supplemental or otherwise. Delivery of the reports, information and documents to the Trustee pursuant to this Section 6.2(b) shall be solely for the purposes of compliance with this Section 6.2(b) and with

-24-

TIA Section 314(a). The Trustee’s receipt of such reports, information and documents shall not constitute notice to it of the consent thereof or of any matter determinable from the content thereof, including the Company’s compliance with any of its covenants hereunder, as to which the Trustee is entitled to rely upon Officers’ Certificates.

Section 6.3 Compliance Certificate. The Company shall deliver to the Trustee within 120 calendar days after the end of each fiscal year of the Company (beginning with the fiscal year ending June 30, 2004) an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof, the Company is in Default in the performance and observance of any of the terms, provisions and conditions of this Indenture and if the Company shall be in Default, specifying all such Defaults and the nature and status thereof of which they may have knowledge.

Section 6.4 Further Instruments and Acts. Upon request of the Trustee, or as otherwise necessary, the Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

Section 6.5 Maintenance of Office or Agency of the Trustee, Registrar, Paying Agent and Conversion Agent. The Company shall maintain in the Borough of Manhattan, New York, New York, an office or agency of the Trustee, Registrar, Paying Agent and Conversion Agent where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer, exchange, redemption, repurchase or conversion and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The office of The Bank of New York shall initially be such office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 13.2.

The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, 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, New York, New York, for such purposes.

Section 6.6 Delivery of Information Required Under Rule 144A. At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder or any beneficial owner of Securities or holder or beneficial owner of Common Stock issued upon conversion thereof, the Company shall promptly furnish or cause to be furnished the information required pursuant to Rule 144A(d)(4) under the Securities Act to such Holder or any beneficial owner of Securities or holder or beneficial owner of Common Stock, or to a prospective purchaser of any such security designated by any such holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such security. Whether a person is a beneficial owner shall be determined by the Company to the Company’s reasonable satisfaction.

-25-

Section 6.7 Waiver of Stay, Extension or Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the principal amount or Designated Event Purchase Price in respect of Securities, or any interest (inclusive of Additional Interest, if any) on such amounts, as contemplated herein, or which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not 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 had been enacted.

Section 6.8 Statement by Officers as to Default. The Company shall deliver to the Trustee, as soon as practicable and in any event within five Business Days after the Company becomes aware of the occurrence of any Default or Event of Default, an Officers’ Certificate setting forth the details of such Default or Event of Default and the action which the Company proposes to take with respect thereto.

Section 6.9 Incurrence of Indebtedness. The Company will not, and will not permit any of its Subsidiaries to, create, incur, assume or directly or indirectly guarantee or in any other manner become directly or indirectly liable for any Indebtedness in an aggregate amount greater than $10 million which has a maturity date at or prior to three years from the Trade Date and which ranks equally with the indebtedness of the Company arising under or in connection with this Indenture. Further, neither the Company nor any of its Subsidiaries shall incur any indebtedness that ranks senior to the Notes.

(a) either (i) the Company shall be the continuing corporation or (ii) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance, transfer, sale, lease or other disposition all or substantially all of the properties and assets of the Company substantially as an entirety (1) shall be organized and validly existing under the laws of the United States or any State thereof or the District of Columbia and (2) shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all of the obligations of the Company under the Securities and this Indenture;

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise) of the properties and assets of one or more Subsidiaries, which, if such assets were owned by the Company, together with the assets of all of the other Subsidiaries of the Company, would constitute all or substantially all of the properties and assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company unless such transfer is to the Company or another Subsidiary.

The successor Person formed by such consolidation or into which the Company is merged or the successor Person to which such conveyance, transfer, sale, lease or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor had been named as the Company herein; and thereafter, except in the case of a conveyance, transfer, sale, lease or other disposition and any obligations the Company may have under a supplemental indenture, the Company shall be discharged from all obligations and covenants under this Indenture and the Securities. Subject to Section 11.6, the Company, the Trustee and the successor Person shall enter into a supplemental indenture to evidence the succession and substitution of such successor Person and such discharge and release of the Company.

Section 8.2 Acceleration. If an Event of Default (other than an Event of Default specified in Section 8.1(i) or Section 8.1(j) with respect to the Company) occurs and is continuing (including an Event of Default specified in Section 8.1(i) or Section 8.1(j) with respect to one or more Designated Subsidiaries), the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding by notice to the Company and the Trustee, may declare the principal amount plus accrued and unpaid interest (inclusive of Additional Interest, if any) on all the Securities to be immediately due and payable. Upon such a declaration, such accelerated amount shall be due and payable immediately.

If an Event of Default specified in Section 8.1(i) or Section 8.1(j) occurs with respect to the Company and is continuing, the principal amount plus accrued and unpaid interest (inclusive of Additional Interest, if any) on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.

The Holders of a majority in aggregate principal amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Holder) may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of the principal amount plus accrued and unpaid interest (inclusive of Additional Interest, if any) that have become due solely as a result of acceleration and if all amounts due to the Trustee under Section 9.7 have been paid. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

-29-

Section 8.3 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy to collect the payment of the principal amount plus accrued and unpaid interest (inclusive of Additional Interest, if any) on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if the Trustee does not possess any of the Securities or does not produce any of the Securities in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 8.4 Waiver of Past Defaults. Subject to Section 8.7 and Section 11.2, the Holders of a majority in aggregate principal amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Holder), may waive an existing Default and its consequences except:

(a) an Event of Default described in Section 8.1(a), Section 8.1(b) or Section 8.1(d);

(b) a Default which constitutes a failure to convert any Security in accordance with the terms of Article XII; or

(c) a Default in respect of any provision of this Indenture or the Securities, which, under Section 11.2, cannot be amended or modified without the consent of each Holder affected thereby.

When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. This Section 8.4 shall be in lieu of Section 316(a)1(B) of the TIA and such Section 316(a)1(B) is hereby expressly excluded from this Indenture, as permitted by the TIA.

Section 8.5 Control by Majority. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines in good faith is prejudicial to the rights of other Holders or would involve the Trustee in personal liability unless the Trustee is provided indemnity satisfactory to it. This Section 8.5 shall be in lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted by the TIA.

Section 8.6 Limitation on Suits. A Holder may not pursue any remedy with respect to this Indenture or the Securities unless:

(a) the Holder gives to the Trustee written notice stating that an Event of Default is continuing;

-30-

(b) the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding make a written request to the Trustee to pursue the remedy;

(c) such Holder or Holders provide to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

(d) the Trustee does not comply with the request within 60 days after receipt of such notice, request and offer of security or indemnity; and

(e) the Holders of a majority in aggregate principal amount of the Securities at the time outstanding do not give the Trustee a direction inconsistent with the request during such 60-day period.

A Holder may not use this Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other Holder.

Section 8.7 Rights of Holders to Receive Payment or to Convert. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the principal amount, Designated Event Purchase Price or interest (inclusive of Additional Interest, if any) in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities and in this Indenture, and to convert such Securities in accordance with Article XII, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, is absolute and unconditional and shall not be impaired or affected adversely without the consent of such Holder.

Section 8.8 Collection Suit by Trustee. If an Event of Default described in Section 8.1(a), Section 8.1(b) or Section 8.1(d) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole amount owing with respect to the Securities and the amounts provided for in Section 9.7.

Section 8.9 Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal amount, Designated Event Purchase Price or interest (inclusive of Additional Interest, if any) in respect of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal amount, Designated Event Purchase Price, or interest (inclusive of Additional Interest, if any) and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel or any other amounts due the Trustee under Section 9.7) and of the Holders allowed in such judicial proceeding, and

-31-

(b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 9.7.

Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 8.10 Priorities. If the Trustee collects any money pursuant to this Article VIII, it shall pay out the money in the following order:

FIRST: to the Trustee for amounts due under Section 9.7;

SECOND: to Holders for amounts due and unpaid on the Securities for the principal amount, Designated Event Purchase Price or interest (inclusive of Additional Interest, if any) as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Securities; and

THIRD: the balance, if any, to the Company.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 8.10. At least 10 calendar days prior to such record date, the Trustee shall mail to each Holder and the Company a notice that states the record date, the payment date and the amount to be paid.

Section 8.11 Undertaking for Costs. 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, a court in its discretion may require the filing by any party litigant (other than the Trustee) in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 8.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 8.7 or a suit by Holders of more than 10% in aggregate principal amount of the Securities at the time outstanding. This Section 8.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA.

The Trustee also shall comply with TIA Section 313(b).

A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each securities exchange, if any, on which the Securities are listed. The Company agrees to notify the Trustee promptly whenever the Securities become listed on any securities exchange and of any delisting thereof.

Section 9.7 Compensation and Indemnity. The Company agrees to:

(a) pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing for all services rendered by it hereunder (which compensation shall not be limited (to the extent permitted by law) by any provision of law in regard to the compensation of a trustee of an express trust);

(b) reimburse the Trustee upon its request for all expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the compensation and the reasonable expenses, advances and disbursements of its agents and counsel), except any such expense, disbursement or advance as shall be determined to have been caused by its own negligence or willful misconduct; and

(c) fully indemnify the Trustee or any predecessor Trustee and their agents for, and to hold them harmless against, any and all loss, damage, claim, liability, cost or expense (including attorney’s fees and expenses, and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) incurred without negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing the provisions of this Section 9.7.

With regard to its indemnification rights under Section 9.7(c) where the Company has assumed the defense in any action or proceeding, the Trustee shall have the right to employ separate counsel in any such action or proceeding and participate in the investigation and defense thereof, and the Company shall pay the reasonable fees and expenses of such separate counsel; provided, however, that the Trustee may only employ separate counsel at the expense of the Company if in the judgment of the Trustee (i) a conflict of interest exists by reason of common

-36-

representation or (ii) there are legal defenses available to the Trustee that are different from or are in addition to those available to the Company or if all parties commonly represented do not agree as to the action (or inaction) of counsel.

To secure the Company’s payment obligations in this Section 9.7, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay the principal amount, Designated Event Purchase Price or interest (inclusive of Additional Interest, if any) as the case may be, on particular Securities.

The Company’s payment obligations pursuant to this Section 9.7 shall survive the discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 8.1(i) or Section 8.1(j), the expenses including the reasonable charges and expenses of its counsel, are intended to constitute expenses of administration under any Bankruptcy Law.

Section 9.8 Replacement of Trustee. The Trustee may resign by so notifying the Company; provided, however, that no such resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 9.8. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may remove the Trustee by so notifying the Trustee and the Company. The Company shall remove the Trustee if:

(a) the Trustee fails to comply with Section 9.10;

(b) the Trustee is adjudged bankrupt or insolvent;

(c) a receiver or public officer takes charge of the Trustee or its property; or

(d) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint, by resolution of its Board of Directors, a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company satisfactory in form and substance to the retiring Trustee and the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, upon payment of all the retiring Trustee’s fees and expenses then due and payable and subject to the lien provided for in Section 9.7.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in aggregate principal amount of the Securities at the time outstanding may petition at the expense of the Company any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee.

-37-

If the Trustee fails to comply with Section 9.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Section 9.9 Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

Section 9.10 Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). The Trustee (or its parent holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. Nothing contained herein shall prevent the Trustee from filing with the Commission the application referred to in the penultimate paragraph of TIA Section 310(b).

Section 9.11 Preferential Collection of Claims Against Company. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein.

ARTICLE X

DISCHARGE OF INDENTURE

Section 10.1 Discharge of Liability on Securities. When (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced or repaid pursuant to Section 2.7) for cancellation or (ii) all outstanding Securities have become due and payable (whether at the Stated Maturity or upon acceleration, or on any Designated Event Purchase Date, or upon conversion) and the Company deposits with the Paying Agent or Conversion Agent cash or Applicable Stock sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.7), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 9.7, cease to be of further effect. The Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’ Certificate and Opinion of Counsel and at the cost and expense of the Company.

Section 10.2 Repayment to the Company. The Trustee and the Paying Agent shall return to the Company upon written request any cash or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled to the cash or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee and the Paying Agent shall have no further liability to the Holders with respect to such cash or securities for that period commencing after the return thereof.

Except as provided below in this Section 11.2, this Indenture or the Securities may be amended, modified or supplemented, and noncompliance in any particular instance with any provision of this Indenture or the Securities may be waived, in each case with the written consent or affirmative vote of the Holders of at least a majority of the principal amount of the Securities at the time outstanding.

Without the written consent or the affirmative vote of each Holder of Securities affected thereby (in addition to the written consent or the affirmative vote of the holders of at least a majority of the principal amount of the Securities at the time outstanding), an amendment or waiver under this Section 11.2 may not:

(a) change the maturity of the principal amount of, or the payment date of any installment of interest (inclusive of Additional Interest, if any) on, any Security;

It shall not be necessary for the consent of the Holders under this Section 11.2 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof.

After an amendment under this Section 11.2 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment.

Nothing contained in this Section 11.2 shall impair the ability of the Company and the Trustee to amend this Indenture or the Securities without the consent of any Holder to provide for the assumption of the Company’s obligations to the Holders of Securities in the case of a merger, consolidation, conveyance, transfer, sale, lease or other disposition pursuant to Article VII.

Section 11.3 Compliance with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall comply with the TIA.

Section 11.4 Revocation and Effect of Consents, Waivers and Actions. Until an amendment, waiver or other action by Holders becomes effective, a consent thereto by a Holder of a Security hereunder is a continuing consent by the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same obligation as the consenting Holder’s Security, even if notation of the consent, waiver or action is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent, waiver or action as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment, waiver or action becomes effective. After an amendment, waiver or action becomes effective, it shall bind every Holder.

Section 11.5 Notation on or Exchange of Securities. Securities authenticated and delivered after the execution of any supplemental indenture pursuant to this Article XI may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture.

Section 11.6 Trustee to Sign Supplemental Indentures. The Trustee shall sign any supplemental indenture authorized pursuant to this Article XI if the amendment contained therein does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such supplemental indenture. In signing such supplemental indenture the Trustee shall receive, and (subject to the provisions of Section 9.1) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

Section 11.7 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

ARTICLE XII

CONVERSION

Section 12.1 Conversion Right. (a) At any time prior to the Stated Maturity subject to and upon compliance with the provisions of this Article XII, a Holder of a Security shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 or an integral multiple of $1,000) of such Security into Common Stock.

Section 12.2 Conversion Procedures; Conversion Rate; Fractional Shares. (a) Each Security shall be convertible at the office of the Conversion Agent into fully paid and nonassessable shares of Common Stock (calculated to the nearest 1/10,000th of a share). The Company shall deliver to such Holder a number of shares of Common Stock equal to (1) the aggregate original principal amount of Securities to be converted plus any accrued and unpaid interest (inclusive of Additional Interest, if any) thereon, divided by 1,000, multiplied by (2) the Conversion Rate.

The Conversion Agent shall notify the Company when it receives a Conversion Notice. The Company shall determine the number of shares of Common Stock that the Holder that submitted the Conversion Notice is entitled to receive upon surrender of the Securities covered by that Conversion Notice. A certificate for the number of full shares of Common Stock into which the Securities are converted (and cash in lieu of fractional shares) shall be delivered to such Holder, assuming all of the other requirements have been satisfied by such Holder, as soon as practicable after receipt of a Conversion Notice. Notwithstanding the foregoing, the Company shall not be required to deliver certificates for Common Stock while the stock transfer books for such stock or the security register are duly closed for any purpose, but certificates for Common Stock shall be issued and delivered as soon as practicable after the opening of such books or security register.

No cash payment of accrued and unpaid interest or Additional Interest shall be paid by the Company on a converted Security, except as described in Section 12.9. Accrued and unpaid interest (inclusive of Additional Interest, if any), shall be deemed to be paid in full with the shares of Common Stock issued upon conversion, rather than deemed cancelled, extinguished or forfeited.

If the Common Stock received upon conversion of a Security pursuant to this Article XII does not include cash sufficient to comply with the United States federal withholding tax obligations imposed by the Code with respect to accrued and unpaid interest on the Securities payable to the beneficial owner of such Security, the Company may, to the extent required by applicable law, recoup or set-off such liability against either the Common Stock to be issued upon conversion to such beneficial owner or any actual cash dividends or distributions subsequently made with respect to such Common Stock to such beneficial owner.

-42-

In the event of a Designated Event, if a Holder has submitted any or all of its Securities for repurchase, a Holder’s conversion rights on the Securities so subject to repurchase shall expire at 5:00 p.m., New York City time, on the Business Day immediately preceding the Designated Event Purchase Date. Notwithstanding the foregoing, a Security in respect of which a Holder has delivered a Designated Event Purchase Notice exercising such Holder’s right to require the Company to repurchase such Security may be converted only if such Designated Event Purchase Notice is withdrawn in accordance with Section 5.2(b) prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Designated Event Purchase Date.

(b) Before any Holder shall be entitled to convert the same into Common Stock, such Holder shall surrender such Securities, duly endorsed to the Company or in blank, at the office of the Conversion Agent, and shall give written notice to the Company at said office or place in the form of the Conversion Notice attached to the Security (the “Conversion Notice”) that such Holder elects to convert the same and shall state in writing therein the principal amount of Securities to be converted (in whole or in part so long as the principal amount to be converted is in multiples of $1,000 principal amount) and the name or names (with addresses) in which such Holder wishes the certificate or certificates for Common Stock to be issued.

Before any such conversion, a Holder also shall pay all funds required, if any, relating to interest (inclusive of Additional Interest, if any), on the Securities, as provided in Section 12.9, and all taxes or duties, if any, as provided in Section 12.8.

If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock that shall be deliverable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted thereby) so surrendered.

If Common Stock to be issued upon conversion of a Restricted Security are to be issued in the name of a Person other than the Holder of such Restricted Security, such Holder shall deliver to the Conversion Agent a certification in substantially the form set forth in a Transfer Certificate dated the date of surrender of such Restricted Security and signed by such Holder, as to compliance with the restrictions on transfer applicable to such Restricted Security. The Company shall not be required to issue Common Stock upon conversion of any such Restricted Security to a Person other than the Holder if such Restricted Security is not so accompanied by a properly completed certification, and the Registrar shall not be required to register Common Stock upon conversion of any such Restricted Security in the name of a Person other than the Holder if such Restricted Security is not so accompanied by a properly completed certification.

(c) A Security shall be deemed to have been converted immediately prior to 5:00 p.m., New York City time, on the date on which all of the conversion requirements set forth in Section 12.2(b) have been satisfied, and the person or persons entitled to receive the Common Stock issuable upon such conversion shall be treated for all purposes as the record Holder or Holders of such Common Stock as of 5:00 p.m., New York City time, on such date.

-43-

(d) In case any Security shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Security so surrendered, without charge to such Holder (subject to the provisions of Section 12.8), a new Security or Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities.

Section 12.3 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time as follows:

(a) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, pay a dividend or make a distribution in Common Stock to all or substantially all holders of its outstanding Common Stock, then the Conversion Rate in effect immediately prior to the close of business on the Record Date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be adjusted so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock which it would have received had such Security been converted immediately prior to the happening of such event as well as such additional shares it would have received as a result of such event. Such adjustment shall become effective immediately prior to the opening of business on the day following the Record Date fixed for such determination. If any dividend or distribution of the type described in this Section 12.3(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared.

(b) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, subdivide its outstanding shares of Common Stock into a greater number of Common Stock or combine its outstanding shares of Common Stock into a smaller number of Common Stock, then the Conversion Rate in effect immediately prior to the close of business on the day upon which such subdivision or combination becomes effective shall be adjusted so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock which it would have received had such Security been converted immediately prior to the happening of such event as well as such additional shares as it would have received as a result of such event.

Such adjustment shall become effective immediately prior to the opening of business on the day following the day upon which such subdivision or combination becomes effective.

(c) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, issue rights or warrants for a period expiring within 60 days (other than any rights or warrants referred to in Section 12.3(d)) to all or substantially all holders of its outstanding Common Stock entitling them to subscribe for or purchase Common Stock (or securities convertible into or exchangeable or exercisable for Common Stock), at a price per share of Common Stock (or having a conversion, exchange or exercise price per share of Common Stock) less than the Closing Sale Price of the Common Stock on the Business Day immediately preceding the date of announcement of such issuance (treating the conversion, exchange or exercise price per share of Common Stock of the securities convertible, exchangeable or exercisable into Common Stock as equal to (x) the sum of (i) the price for a unit

-44-

of the security convertible into or exchangeable or exercisable for Common Stock and (ii) any additional consideration initially payable upon the conversion of or exchange or exercise for such security into Common Stock divided by (y) the number of shares of Common Stock initially underlying such convertible, exchangeable or exercisable security), then the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect at the opening of business on the date after such date of announcement by a fraction:

(i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of announcement, plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible, exchangeable or exercisable securities so offered are convertible, exchangeable or exercisable); and

(ii) the denominator of which shall be the number of shares of Common Stock outstanding on the close of business on the date of announcement, plus the number of shares of Common Stock (or convertible, exchangeable or exercisable securities) which the aggregate offering price of the total number of shares of Common Stock (or convertible, exchangeable or exercisable securities) so offered for subscription or purchase (or the aggregate conversion, exchange or exercise price of the convertible, exchangeable or exercisable securities so offered) would purchase at such Closing Sale Price of the Common Stock.

Such adjustment shall become effective immediately prior to the opening of business on the day following the Record Date for such determination. To the extent that shares of Common Stock (or securities convertible, exchangeable or exercisable into shares of Common Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible, exchangeable or exercisable into shares of Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Closing Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value of such consideration if other than cash, to be determined by the Board of Directors.

(d) (i) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, by dividend or otherwise, distribute to all or substantially all holders of its outstanding shares of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation and the shares of Common Stock are not changed or exchanged), shares of its capital stock, evidences of its Indebtedness or other assets, including securities, but excluding (i) dividends or distributions of Common Stock referred to in Section 12.3(a), (ii) any rights or warrants referred to in Section 12.3(c), (iii) dividends and distributions paid exclusively in cash referred to in

-45-

Section 12.3(e) and (iv) dividends and distributions of stock, securities or other property or assets (including cash) in connection with the reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.4 applies (such capital stock, evidence of its indebtedness, other assets or securities being distributed hereinafter in this Section 12.3(d) called the “distributed assets”), then, in each such case, subject to paragraphs (D) and (E) of this Section 12.3(d), the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction:

(A) the numerator of which shall be the Current Market Price; and

(B) the denominator of which shall be such Current Market Price of the Common Stock, less the Fair Market Value on such date of the portion of the distributed assets so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Record Date) on such date.

Such adjustment shall become effective immediately prior to the opening of business on the day following the Record Date for such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such dividend or distribution had not been declared.

(ii) If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 12.3(d) by reference to the actual or when issued trading market for any distributed assets comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the “Reference Period”) used in computing the Current Market Price pursuant to Section 12.3(g) to the extent possible, unless the Board of Directors determines in good faith that determining the Fair Market Value during the Reference Period would not be in the best interest of the Holders.

(iii) In the event any such distribution consists of shares of capital stock of, or similar equity interests in, one or more of the Company’s Subsidiaries (a “Spin Off”), the Fair Market Value of the securities to be distributed shall equal the average of the Closing Sale Prices of such securities on the principal securities market on which such securities are traded for the five consecutive Trading Days commencing on and including the sixth Trading Day of those securities after the effectiveness of the Spin Off, and the Current Market Price shall be measured for the same period. In the event, however, that an underwritten initial public offering of the securities in the Spin Off occurs simultaneously with the Spin Off, Fair Market Value of the securities distributed in the Spin Off shall mean the initial public offering price of such securities and the Current Market Price shall mean the Closing Sale Price for the Common Stock on the same Trading Day.

(iv) Rights or warrants distributed by the Company to all holders of its outstanding shares of Common Stock entitling them to subscribe for or purchase shares

-46-

of Equity Interest (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”), (x) are deemed to be transferred with such Common Stock, (y) are not exercisable and (z) are also issued in respect of future issuances of Common Stock shall be deemed not to have been distributed for purposes of this Section 12.3(d) (and no adjustment to the Conversion Rate under this Section 12.3(d) shall be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different distributed assets, evidences of indebtedness or other assets, or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and Record Date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Rate under this Section 12.3(d):

(A) in the case of any such rights or warrants which shall all have been redeemed or purchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or purchase 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 Purchase Price received by a holder of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or purchase; and

(B) in the case of such rights or warrants which shall have expired or been terminated without exercise, the Conversion Rate shall be readjusted as if such rights and warrants had never been issued.

(v) For purposes of this Section 12.3(d) and Section 12.3(a), Section 12.3(b) and Section 12.3(c), any dividend or distribution to which this Section 12.3(d) is applicable that also includes (x) Common Stock, (y) a subdivision or combination of Common Stock to which Section 12.3(b) applies or (z) rights or warrants to subscribe for or purchase Common Stock to which Section 12.3(c) applies (or any combination thereof), shall be deemed instead to be:

(A) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants, other than such Common Stock, such subdivision or combination or such rights or warrants to which Section 12.3(a), Section 12.3(b) and Section 12.3(c) apply, respectively (and any Conversion Rate adjustment required by this Section 12.3(d) with respect to such dividend or distribution shall then be made), immediately followed by

(B) a dividend or distribution of such Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion Rate

-47-

adjustment required by Section 12.3(a), Section 12.3(b) and Section 12.3(c) with respect to such dividend or distribution shall then be made), except:

(1) the Record Date of such dividend or distribution shall be substituted as (i) ”the date fixed for the determination of stockholders entitled to receive such dividend or other distribution,” “Record Date fixed for such determinations” and “Record Date” within the meaning of Section 12.3(a), (ii) ”the day upon which such subdivision or combination becomes effective” within the meaning of Section 12.3(b), and (iii) as “the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants” and such “Record Date” within the meaning of Section 12.3(c); and

(2) any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution.

(e) In case the Company shall, at any time or from time to time after the initial Issue Date while any of the Securities are outstanding, by dividend or otherwise, distribute to all or substantially all holders of its outstanding shares of Common Stock, cash (including any quarterly cash dividends, but excluding any cash that is distributed upon a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.4 applies or as part of a distribution referred to in Section 12.3(d)), then, and in each case, immediately after the close of business on such date, the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to the close of business of such Record Date by a fraction:

(i) the numerator of which shall be equal to the Current Market Price on such date; and

(ii) the denominator of which shall be equal to the Current Market Price on the Record Date, less an amount equal to the quotient of (x) the aggregate amount of such cash distribution and (y) the number of shares of Common Stock outstanding on the Record Date.

Such adjustment shall become effective immediately prior to the opening of business on the day following the Record Date for such distribution. In the event that such distribution is not so made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such distribution had not been declared.

(f) In case a tender offer or exchange offer (other than as part of a stock option exchange offer) made by the Company or any of its Subsidiaries for all or any portion of the Common Stock shall expire, then and in each such case, immediately prior to the opening of business on the day after the date of the last time (the “Expiration Time”) tenders or exchanges could have been made pursuant to such tender offer or exchange offer, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate

-48-

in effect immediately prior to the close of business on the date of the Expiration Time by a fraction:

(i) the numerator of which shall be the sum of (x) the product of (i) the number of shares of Common Stock outstanding (excluding any tendered or exchanged shares) at the Expiration Time and (ii) the Current Market Price of the Common Stock at the Expiration Time, and (y) the Fair Market Value of the aggregate consideration payable to stockholders based on acceptance (up to any maximum specified in the terms of the tender offer or exchange offer) of all shares validly tendered and not withdrawn as of the Expiration Time; and

(ii) the denominator of which shall be the product of the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time and the Current Market Price of the Common Stock at the Expiration Time.

Such adjustment (if any) shall 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 or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all or a portion of such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such (or such portion of the) tender offer or exchange offer had not been made. If the application of this Section 12.3(e) to any tender offer or exchange offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer under this Section 12.3(e).

To the extent the Company has a rights plan in effect upon the conversion of the Securities, if Holders of the Securities exercising the right of conversion attaching after the date the rights separate from the underlying Common Stock are not entitled to receive the rights that would otherwise be attributable to the Common Stock received upon conversion, the Conversion Rate shall be adjusted as though the rights were being distributed to holders of Common Stock on the date of such separation. If such an adjustment is made and the rights are later redeemed, invalidated or terminated, then a corresponding reversing adjustment shall be made to the Conversion Rate on an equitable basis.

(g) For purposes of this Article XII, the following terms shall have the meanings indicated:

“Current Market Price” on any date means the average of the daily Closing Sale Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to such date; provided, however, that if:

(i) the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 12.3(a), Section 12.3(b), Section 12.3(c), Section 12.3(d), Section 12.3(e) or Section 12.3(f) occurs during such ten consecutive Trading Days, the Closing Sale Price for each Trading Day prior to the “ex” date for such other event shall be adjusted by multiplying such Closing Sale Price by the same fraction by which the Conversion Rate is so required to be adjusted as a result of such other event;

-49-

(ii) the “ex” date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 12.3(a), Section 12.3(b), Section 12.3(c), Section 12.3(d), Section 12.3(e) or Section 12.3(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 Sale Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by multiplying such Closing Sale Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event; and

(iii) the “ex” date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (i) or (ii) of this proviso, the Closing Sale 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 12.3(d), Section 12.3(e) or Section 12.3(f)) 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 12.3(e), if the “ex” date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 12.3(a), Section 12.3(b), Section 12.3(c), Section 12.3(d), Section 12.3(e) or Section 12.3(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 Sale Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by multiplying such Closing Sale Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term “ex” date, when used:

(i) with respect to any issuance or distribution, means the first date on which the Common Stock trade regular way on the relevant exchange or in the relevant market from which the Closing Sale Price was obtained without the right to receive such issuance or distribution;

(ii) with respect to any subdivision or combination of Common Stock, means the first date on which the Common Stock trade regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective; and

(iii) with respect to any tender offer or exchange offer, means the first date on which the Common Stock trade regular way on such exchange or in such market after the Expiration Time of such offer.

Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are called for pursuant to this Section 12.3, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 12.3 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

-50-

“Fair Market Value” means the amount which a willing buyer would pay a willing seller in an arm’s-length transaction (as determined by the Board of Directors, whose determination shall be made in good faith and, absent manifest error, shall be final and binding on Holders of the Securities).

“Record Date” means, 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 stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

(h) The Company shall be entitled to make such additional adjustments in the Conversion Rate, in addition to those required by Section 12.3(a), Section 12.3(b), Section 12.3(c), Section 12.3(d), Section 12.3(e) or Section 12.3(f) if the Board of Directors determines that it is advisable, subject to compliance with Nasdaq Marketplace Rule 4350(i), in order that any dividend or distribution of Common Stock, any subdivision, reclassification or combination of Common Stock or any issuance of rights or warrants referred to above shall not be taxable to the holders of Common Stock for United States Federal income tax purposes.

(i) To the extent permitted by applicable law, the Company may, from time to time, increase the Conversion Rate by any amount for any period of time if such period is at least 20 calendar days, the increase is irrevocable during the period and the Board of Directors, in good faith and absent manifest error, determines that such increase would be in the best interest of the Company, subject to compliance with Nasdaq Marketplace Rule 4350(i). Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the Trustee and each Holder at the address of such Holder as it appears in the register of the Securities maintained by the Registrar, at least 15 calendar days prior to the date the increased Conversion Rate takes effect, a notice of the increase stating the increased Conversion Rate and the period during which it shall be in effect.

(j) In any case in which this Section 12.3 shall require that any adjustment be made effective as of or retroactively immediately following a Record Date, the Company may elect to defer (but only for five Trading Days following the filing of the notice referred to in Section 12.5) issuing to the Holder of any Securities converted after such Record Date the Common Stock issuable upon such conversion over and above the Common Stock issuable upon such conversion on the basis of the Conversion Rate prior to adjustment; provided, however, that the Company shall deliver to such Holder a due xxxx or other appropriate instrument evidencing such Holder’s right to receive such additional Common Stock upon the occurrence of the event requiring such adjustment.

(k) All calculations under this Section 12.3 shall be made to the nearest cent or one hundredth of a share, with one-half cent and 0.005 of a share, respectively, being rounded upward. Notwithstanding any other provision of this Section 12.3, the Company shall not be

-51-

required to make any adjustment of the Conversion Rate unless such adjustment would require an increase or decrease of at least 1% in the Conversion Rate as last adjusted. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment which, together with any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at least 1% in the Conversion Rate as last adjusted. Any adjustments under this Section 12.3 shall be made successively whenever an event requiring such an adjustment occurs.

(l) In the event that at any time, as a result of an adjustment made pursuant to this Section 12.3, the Holder of any Securities thereafter surrendered for conversion shall become entitled to receive any shares of stock of the Company other than Common Stock into which the Securities originally were convertible, the Conversion Rate of such other shares so receivable upon conversion of any such Security shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained in subparagraphs (a) through (j) of this Section 12.3, and the provision of Section 12.1, Section 12.2 and Section 12.4 through Section 12.9 with respect to the Common Stock shall apply on like or similar terms to any such other shares and the determination of the Board of Directors as to any such adjustment shall be conclusive.

(m) No adjustment shall be made pursuant to this Section 12.3 if (i) the effect thereof would be to reduce the Conversion Price below the par value (if any) of the Common Stock or (ii) any dividend, distribution or issuance that would otherwise give rise to an adjustment pursuant to this Section 12.3 is made or paid to the Holders of the Securities.

Section 12.4 Consolidation or Merger of the Company. If any of the following events occurs, namely:

(a) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination);

(b) any merger, consolidation, statutory share exchange 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

(c) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock;

the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture, if such supplemental indenture is then required to so comply) providing that such Securities shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) which such Holder would have been entitled to receive upon such reclassification, change, merger,

-52-

consolidation, statutory share exchange, combination, sale or conveyance had such Securities been converted into Common Stock immediately prior to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance (provided, that if the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“Non Electing Share”), then for the purposes of this Section 12.4, the kind and amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance for each Non Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non Electing Shares). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article XII. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing.

The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Securities maintained by the Registrar, 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 12.4 shall similarly apply to successive reclassifications, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances.

If this Section 12.4 applies to any event or occurrence, Section 12.3 shall not apply.

Section 12.5 Notice of Adjustment. Whenever an adjustment in the Conversion Rate with respect to the Securities is required:

(a) the Company shall forthwith place on file with the Trustee and any Conversion Agent for such securities a certificate of the Chief Financial Officer of the Company, stating the adjusted Conversion Rate determined as provided herein and setting forth in reasonable detail such facts as shall be necessary to show the reason for and the manner of computing such adjustment; and

(b) a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate shall forthwith be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company, to each Holder in the manner provided in Section 13.2. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice.

-53-

Section 12.6 Notice in Certain Events. In case of:

(a) a consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or conveyance to another Person or entity or group of Persons or entities acting in concert as a partnership, limited partnership, syndicate or other group (within the meaning of Rule 13d 3 under the Exchange Act) of all or substantially all of the property and assets of the Company; or

(b) the voluntary or involuntary dissolution, liquidation or winding up of the Company; or

(c) any action triggering an adjustment of the Conversion Rate referred to in clause (x) or (y) below;

then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent, and shall cause to be given, to the Holders of the Securities in the manner provided in Section 13.2, at least 15 days prior to the applicable date hereinafter specified, a notice stating:

(x) the date on which a record is to be taken for the purpose of any distribution or grant of rights or warrants triggering an adjustment to the Conversion Rate pursuant to this Article XII, or, if a record is not to be taken, the date as of which the holders of record of Common Stock entitled to such distribution, rights or warrants are to be determined; or

(y) the date on which any reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up triggering an adjustment to the Conversion Rate pursuant to this Article XII is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up.

Failure to give such notice or any defect therein shall not affect the legality or validity of the proceedings described in Section 12.6(a), Section 12.6(b) or Section 12.6(c).

Section 12.7 Company to Reserve Stock: Registration; Listing. (a) The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of the Securities, such number of its duly authorized Common Stock as shall from time to time be sufficient to effect the conversion of all Securities then outstanding into such Common Stock at any time (assuming that, at the time of the computation of such number of Common Stock, all such Securities would be held by a single Holder). The Company covenants that all Common Stock which may be issued upon conversion of Securities shall upon issue be fully paid and nonassessable and free from all liens and charges and, except as provided in Section 12.8, taxes with respect to the issue thereof.

-54-

(b) If any Common Stock which would be issuable upon conversion of Securities hereunder require registration with or approval of any governmental authority before such shares or securities may be issued upon such conversion, the Company shall use its reasonable best efforts to cause such shares or securities to be duly registered or approved, as the case may be. The Company further covenants that so long as the Common Stock shall be quoted on the Nasdaq National Market system, the Company shall use its reasonable best efforts, if permitted by the rules of the Nasdaq National Market system, to keep so quoted all Common Stock issuable upon conversion of the Securities, and the Company shall use its reasonable best efforts to list or obtain approval for the quotation of the Common Stock to be delivered upon conversion of the Securities prior to such delivery upon any other national securities exchange or quotation system upon which the outstanding Common Stock is listed or quoted at the time of such delivery.

Section 12.8 Taxes on Conversion. The issue of stock certificates on conversion of Securities shall be made without charge to the converting Holder for any documentary, stamp or similar issue or transfer taxes in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue or delivery of Common Stock or the portion, if any, of the Securities which are not so converted in a name other than that in which the Securities so converted were registered, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of such tax or has established to the satisfaction of the Company that such tax has been paid.

Section 12.9 Conversion After Regular Record Date. Except as provided in the succeeding paragraph, the Holder of such Securities shall not be entitled to receive any accrued and unpaid interest or Additional Interest, if any.

If any Securities are surrendered for conversion subsequent to the close of business on any Regular Record Date but prior to the opening of business on the corresponding Interest Payment Date, the Holder of such Securities at the close of business on such Regular Record Date shall receive the interest (inclusive of Additional Interest, if any), payable on such Securities on such Interest Payment Date notwithstanding the conversion thereof. Securities surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the corresponding Interest Payment Date shall be accompanied by payment by Holders, for the account of the Company, in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest (inclusive of Additional Interest, if any), payable on such interest payment date on the Securities being surrendered for conversion.

Except as provided in Section 12.2(a) and this Section 12.9, no payment or adjustment shall be made in respect of dividends or distributions on the Common Stock issued upon conversion or accrued and unpaid interest (inclusive of Additional Interest, if any), on a converted Security.

-55-

Section 12.10 Company Determination Final. Any determination that the Company or the Board of Directors must make pursuant to this Article XII shall be conclusive if made in good faith and in accordance with the provisions of this Article, absent manifest error, and set forth in a Board Resolution.

Section 12.11 Responsibility of Trustee for Conversion Provisions. The Trustee has no duty to determine when an adjustment under this Article XII should be made, how it should be made or what it should be. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities. The Trustee shall not be responsible for any failure of the Company to comply with this Article XII. Each Conversion Agent other than the Company shall have the same protection under this Section 12.11 as the Trustee.

The rights, privileges, protections, immunities and benefits given to the Trustee under this Indenture including, without limitation, its rights to be indemnified, are extended to, and shall be enforceable by, other than the Company, the Trustee in each of its capacities hereunder, and each Paying Agent or Conversion Agent, other than the Company, acting hereunder.

Section 12.12 Unconditional Right of Holders to Convert. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to convert its Security in accordance with this Article XII and to bring an action against the Company for the enforcement of any such right to convert, and such rights shall not be impaired or affected without the consent of such Holder.
