Item 1.01. Entry into a Material Definitive Agreement.

Pursuant to an Underwriting Agreement dated as of February 6, 2008 (the “Underwriting Agreement”), between RadiSys Corporation (the “Company”) and Credit Suisse Securities (USA) LLC (the “Underwriter”), the Company made a public offering of $55.0 million aggregate principal amount of its 2.75% convertible senior notes due 2013 (the “Notes”) (including the underwriter’s option to purchase additional $5.0 million aggregate principal amount of Notes to cover over-allotments). The offering of the Notes was registered under the Securities Act of 1933 and is being made pursuant to the Company’s Registration Statement on Form S-3 (Reg. No. 333-146977) and the Prospectus included therein, declared effective by the Securities and Exchange Commission (the “Commission”) on November 7, 2007, the Prospectus Supplement relating thereto dated February 6, 2007 and the Free Writing Prospectuses filed with the Commission on February 5 and February 7, 2008. The Underwriting Agreement includes customary representations, warranties and covenants by the Company. It also provides for customary indemnification by each of the Company and the Underwriter against certain liabilities arising out of or in connection with sale of the Notes and customary contribution provisions in respect of those liabilities.

The foregoing description of the material terms of the Underwriting Agreement is qualified in its entirety by reference to the Underwriting Agreement which is attached to this report as Exhibit 1.1 and is incorporated herein by reference.

The Notes will be issued pursuant to an indenture, to be dated as of February 12, 2008 (the “Base Indenture”), by and between the Company and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”), supplemented by the First Supplemental Indenture dated as of February 12, 2008, between the Company and the Trustee (the “Supplemental Indenture,” and together, the Base Indenture, the “Indenture”). The Notes will be represented by a global security, executed by the Company, in the form attached to the Supplemental Indenture.

The Notes are general unsecured obligations of the Company ranking equally with all of the Company’s existing and future senior indebtedness. The Notes will bear interest at a rate of 2.75% per annum from the date of issuance, payable semi-annually, in arrears, on each August 15 and February 15, beginning on August 15, 2008. The Notes mature on February 15, 2013. The Notes will be convertible into the Company’s common stock at an initial conversion rate of 76.7448 shares of common stock per $1,000 principal amount of the Notes (which is equivalent to a conversion price of approximately $13.03 per share), subject to adjustment upon the occurrence of certain events.

Holders of the Notes may require the Company to repurchase the Notes for cash equal to 100% of the principal amount to be repurchased plus accrued and unpaid interest upon the occurrence of a fundamental change in accordance with the Indenture. In addition, if certain fundamental changes occur, the Company may be required in certain circumstances to increase the conversion rate for any Notes converted in connection with such fundamental changes by a specified number of shares of the Company’s common stock.

The Indenture includes customary agreements and covenants by the Company. The foregoing description of the material terms of the Base Indenture and the Supplemental Indenture is qualified in its entirety by reference to each of the Base Indenture and the Supplemental Indenture, which are attached to this report as Exhibit 4.1 and Exhibit 4.2, respectively, and are incorporated herein by reference.

In connection with the offering of the Notes, the Company entered into a capped call transaction with an affiliate of the Underwriter. The capped call transaction is expected to reduce the potential dilution upon conversion of the Notes. However, the dilution mitigation under the capped call will be limited to the extent that the market value per share of the Company’s common stock exceeds such cap price. The capped call transaction has a cap price of $23.085, which is approximately 125% higher than the closing price of the Company’s common stock on February 6, 2008. In connection with hedging the capped call transaction, the counterparty or its affiliates expect to purchase the Company’s common stock and/or enter into various derivative transactions with respect to the Company’s common stock concurrently with or shortly after the pricing of the Notes. In addition, the counterparty or its affiliates may then enter into or unwind various derivative transactions and/or purchase or sell the Company’s common stock in secondary market transactions following the pricing of the Notes. These activities could have the effect of increasing or preventing a decline in the price of the Company’s common stock concurrently with or following the pricing of the Notes.

Any third-party statistical and market-related data included or incorporated by reference in a Registration Statement, a Statutory Prospectus or the General Disclosure Package are based on or derived from sources that the Company believes to be reliable and accurate.

(y) Internal Controls and Compliance with the Sarbanes-Oxley Act. Except as set forth in the General Disclosure Package, the Company, its subsidiaries and the Company’s Board of Directors (the “Board”) are in compliance in all material respects with Sarbanes-Oxley and all applicable rules under the Exchange Act. The Company maintains a system of internal controls, including, but not limited to, disclosure controls and procedures, internal controls over accounting matters and financial reporting and legal and regulatory compliance controls (collectively, “Internal Controls”) that are sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Internal Controls are, or upon consummation of the offering of the Offered Securities will be, overseen by the Audit Committee (the “Audit Committee”) of the Board in accordance with Exchange Rules. The Company has not publicly disclosed or reported to the Audit Committee or the Board, and within the next 90 days the Company does not reasonably expect to publicly disclose or report to the Audit Committee or the Board, a significant deficiency, material weakness, change in Internal Controls or fraud involving management or other employees who have a significant role in Internal Controls (each, an “Internal Control Event”), any violation of, or failure to comply with, the Securities Laws, or any matter which, if determined adversely, would have a Material Adverse Effect.

(z) Absence of Accounting Issues. A member of the Audit Committee has confirmed to the Chief Executive Officer or the Chief Financial Officer that, except as set forth in the General

7

On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, the Company agrees to sell to the Underwriter, and the Underwriter agrees to purchase from the Company, at a purchase price of 96.5% of the principal amount thereof plus accrued interest from February 12, 2008 to the First Closing Date (as hereinafter defined), the Firm Securities.

The Company will deliver the Firm Securities to or as instructed by the Underwriter in a form reasonably acceptable to the Underwriter against payment of the purchase price by the Underwriter in Federal (same day) funds by wire transfer to an account at a bank acceptable to Credit Suisse drawn to the order of Radisys Corporation at the office of Davis Polk & Wardwell, 1600 El Camino Real, Menlo Park, California 94025, at 10:00 A.M., New York time, on February 12, 2008, or at such other time not later than seven full business days thereafter as the Underwriter and the Company determine, such time being herein referred to as the “First Closing Date”. For purposes of Rule 15c6-1 under the Securities Exchange Act of 1934, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering. The Firm Securities so to be delivered or evidence of their issuance will be made available for checking at the above office of Davis Polk & Wardwell at least 24 hours prior to the First Closing Date.

In addition, upon written notice from the Underwriter given to the Company from time to time not more than 30 days subsequent to the date of the Final Prospectus, the Underwriter may purchase all or less than all of the Optional Securities at the purchase price per principal amount of Securities (including any accrued interest thereon to the related Optional Closing Date) to be paid for the Firm Securities.

5. Certain Agreements of the Company. The Company agrees with the Underwriter that:

(a) Filing of Prospectuses. The Company has filed or will file each Statutory Prospectus (including the Final Prospectus) pursuant to and in accordance with Rule 424(b)(2) (or, if applicable and consented to by the Underwriter, subparagraph (5)) not later than the second business day following the earlier of the date it is first used or the execution and delivery of this Agreement. The Company has complied and will comply with Rule 433.

(b) Filing of Amendments; Response to Commission Requests. The Company will promptly advise the Underwriter of any proposal to amend or supplement the Registration Statement or any Statutory Prospectus at any time and will offer the Underwriter a reasonable opportunity to comment on any such amendment or supplement; and the Company will also advise the Underwriter promptly of (i) the filing of any such amendment or supplement, (ii) any request by the Commission or its staff for any amendment to the Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iii) the institution by the Commission of any stop order proceedings in respect of the Registration Statement or the threatening of any proceeding for that purpose, and (iv) the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by the Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will promptly notify the Underwriter of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriter and the dealers and any other dealers upon request of the Underwriter, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Underwriter’s consent to, nor the Underwriter’s delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

As soon as practicable, but not later than 16 months, after the date of this Agreement, the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the date of this Agreement and satisfying the provisions of Section 11(a) of the Act and Rule 158.

The Company will pay the expenses of printing and distributing to the Underwriter all such documents.

However, so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”), it is not required to furnish such reports or statements to the Underwriter.

(i) Use of Proceeds. The Company will use the net proceeds received in connection with this offering in the manner described in the “Use of Proceeds” section of the General Disclosure Package and, except as disclosed in the General Disclosure Package, the Company does not intend to use any of the proceeds from the sale of the Offered Securities hereunder to repay any outstanding debt owed to any affiliate of the Underwriter.

The initial Lock-Up Period will commence on the date hereof and continue for 90 days after the date hereof or such earlier date that the Underwriter consents to in writing.

6. Free Writing Prospectuses. (a) Issuer Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior consent of Credit Suisse, and the Underwriter represents and agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission, except of any term sheet containing a description of the terms of the Offered Securities or their offering either that does not reflect the final terms or that is included in the final term sheet contemplated in Section 6(b) hereof. Any such free writing prospectus consented to by the Company and Credit Suisse is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filings where required, legending and record keeping.

Any such final term sheet is an Issuer Free Writing Prospectus and a Permitted Free Writing Prospectus for purposes of this Agreement. The Company also consents to the use by the Underwriter of a free writing prospectus that contains only (i)(x) information describing the preliminary terms of the Offered Securities or their offering or (y) information that describes the final terms of the Offered Securities or their offering and that is included in the final term sheet of the Company contemplated in the first sentence of this subsection or (ii) other information that is not “issuer information,” as defined in Rule 433, it being understood that any such free writing prospectus referred to in clause (i) or (ii) above shall not be an Issuer Free Writing Prospectus for purposes of this Agreement.

The Company will indemnify and hold harmless the Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by the Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by the Underwriter consists of the information described as such in subsection (b) below.

14

(b) Indemnification of Company. The Underwriter will indemnify and hold harmless the Company, each of its directors and each of its officers who signs a Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”), against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by the Underwriter specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by the Underwriter consists of the following information in the Final Prospectus furnished on behalf of the Underwriter: the concession disclosure appearing in the fourth paragraph under the caption “Underwriting” and the information contained in the tenth and eleventh paragraphs under the caption “Underwriting.”

(c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other

15

from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriter. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Company and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8(d).

9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by the Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriter is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 7(f)(iii)–(viii) hereof or if the Underwriter defaults in its obligation to purchase Offered Securities hereunder, the Company will reimburse the Underwriter for all out-of-pocket accountable expenses (including reasonable and documented fees and disbursements of counsel) reasonably incurred by it in connection with the offering of the Offered Securities, and the respective obligations of the Company and the Underwriter pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.

No such request, demand, authorization, direction, notice, consent, waiver or other Act shall be valid or effective if made, given or taken more than 90 days after such record date.

(2) The fact and date of the execution by any Person of any such instrument or writing referred to in this Section 1.4 may be proved in any reasonable manner which the Trustee deems sufficient and in accordance with such reasonable rules as the Trustee may determine; and the Trustee may in any instance require further proof with respect to any of the matters referred to in this Section.

(3) The ownership, principal amount and serial numbers of Registered Securities held by any Person, and the date of the commencement and the date of the termination of holding the same, shall be proved by the Security Register.

(4) If the Company shall solicit from the Holders of any Registered Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may at its option (but is not obligated to), by Board Resolution, fix in advance a record date for the determination of Holders of Registered Securities entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of Registered Securities of record at the close of business on such record date shall be deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders of Registered Securities shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

11

(5) Any request, demand, authorization, direction, notice, consent, waiver or other Act by the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done or suffered to be done by the Trustee, any Security Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such Act is made upon such Security.

Section 1.6 Notice to Holders of Securities; Waiver.

Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture provides for notice to Holders of Securities of any event, such notice shall be sufficiently given to Holders of Registered Securities if in writing and mailed, first-class postage prepaid, to each Holder of a Registered Security affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities given as provided herein. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided. In the case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

12

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in The City of New York or a day on which banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to be closed.

(18) whether any of such Securities are to be issuable upon the exercise of warrants, and the time, manner and place for such Securities to be authenticated and delivered;

(21) whether the Securities are senior or subordinated debt securities, and if subordinated debt securities, the terms of such subordination.

(22) any other terms of such Securities and any deletions from or modifications or additions to this Indenture in respect of such Securities. All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided by the Company in or pursuant to the Board Resolution and set forth in the Officers’ Certificate or in any indenture or indentures supplemental hereto pertaining to such series of Securities. The terms of the Securities of any series may provide, without limitation, that the Securities shall be authenticated and delivered by the Trustee on original issue from time to time upon telephonic or written order of persons designated in the Officers’ Certificate or supplemental indenture (telephonic instructions to be promptly confirmed in writing by such person) and that such persons are authorized to determine, consistent with such Officers’ Certificate or any applicable supplemental indenture, such terms and conditions of the Securities of such series as are specified in such Officers’ Certificate or supplemental indenture. All Securities of any one series

19

need not be issued at the same time and, unless otherwise so provided by the Company, a series may be reopened for issuances of additional Securities of such series or to establish additional terms of such series of Securities. If any of the terms of the Securities of any series shall be established by action taken by or pursuant to a Board Resolution, the Board Resolution shall be delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of such series.

Section 3.2 Currency; Denominations.

Unless otherwise provided in or pursuant to this Indenture or any Security, the principal of, any premium and interest on and any Additional Amounts with respect to the Securities shall be payable in Dollars. Unless otherwise provided in or pursuant to this Indenture, Registered Securities denominated in Dollars shall be issuable in registered form without coupons in denominations of $1,000 and any integral multiple thereof. Securities not denominated in Dollars shall be issuable in such denominations as are established with respect to such Securities in or pursuant to this Indenture.

Section 3.3 Execution, Authentication, Delivery and Dating.

Securities shall be executed on behalf of the Company by its Chairman of the Board, one of its Vice Chairmen, its President, its Treasurer, Assistant Treasurer, one of its Vice Presidents or other person authorized by resolution of the Board of Directors of the Company. The signature of any of these officers on the Securities may be manual or facsimile.

Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities, executed by the Company, to the Trustee for authentication and, provided that the Board Resolution and Officers’ Certificate or supplemental indenture or indentures with respect to such Securities referred to in Section 3.1 and a Company Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the provisions hereof and of such Securities shall authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be provided with, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon,

(1) an Opinion of Counsel to the effect that:

(a) the form or forms and terms of such Securities have been established in conformity with the provisions of this Indenture;

(b) all conditions precedent to the authentication and delivery of such Securities have been complied with and that such Securities, when completed by appropriate insertions, executed under the Company’s corporate seal and attested by duly authorized officers of the Company, delivered by duly authorized officers of the Company to the Trustee for authentication pursuant to this Indenture, and authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute legally valid and binding obligations of the Company, enforceable against the Company in

20

accordance with their terms, except as enforcement thereof may be subject to or limited by bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer or other similar laws relating to or affecting creditors’ rights generally, and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law) and will entitle the Holders thereof to the benefits of this Indenture; such Opinion of Counsel need express no opinion as to the availability of equitable remedies;

(c) all laws and requirements in respect of the execution and delivery by the Company of such Securities have been complied with;

and, to the extent that this Indenture is required to be qualified under the Trust Indenture Act in connection with the issuance of such Securities, to the further effect that:

(d) this Indenture has been qualified under the Trust Indenture Act; and

(2) an Officers’ Certificate stating that all conditions precedent to the execution, authentication and delivery of such Securities have been complied with and that, to the best knowledge of the Persons executing such certificate, no event which is, or after notice or lapse of time would become, an Event of Default with respect to any of the Securities shall have occurred and be continuing.

The Trustee shall not be required to authenticate or to cause an Authenticating Agent to authenticate any Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee or if the Trustee, being advised by counsel, determines that such action may not lawfully be taken.

Each Registered Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form provided for in Section 2.2 or Section 6.12 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual or facsimile signature of one of its authorized officers. Such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

Section 3.4 Temporary Securities.

Pending the preparation of definitive Securities, the Company may execute and deliver to the Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided in Section 3.3, temporary Securities in lieu thereof 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, in registered form and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Company executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form.

Except in the case of temporary Securities in global form, which shall be exchanged in accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities of the same series and containing terms and provisions that are identical to

21

those of any temporary Securities, such temporary Securities shall be exchangeable for such definitive Securities upon surrender of such temporary Securities at an Office or Agency for such Securities, without charge to any Holder thereof. 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 of the same series and containing identical terms and provisions. Unless otherwise provided in or pursuant to this Indenture with respect to a temporary global Security, until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series.

Section 3.5 Registration, Transfer and Exchange.

With respect to the Registered Securities of each series, if any, the Company shall cause to be kept a register (each such register being herein sometimes referred to as the “Security Register”) at an Office or Agency for such series in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the Registered Securities of such series and of transfers of the Registered Securities of such series.

Such Office or Agency shall be the “Security Registrar” or “Registrar” for that series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar for each series of Securities. The Company shall have the right to remove and replace from time to time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by the Company and shall have accepted such appointment by the Company. In the event that the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for each series of Securities.

Upon surrender for registration of transfer of any Registered Security of any series at any Office or Agency for such series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions.

At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Office or Agency for such series. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive.

A global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture, any global Security shall be exchangeable for definitive Securities only if (i) the Depository is at any time unwilling, unable or ineligible to continue as

22

Depository and a successor depository is not appointed by the Company within 90 days of the date the Company is so informed in writing, (ii) the Depositary ceases to be a clearing agency registered under the Exchange Act of 1934, (iii) the Company executes and delivers to the Trustee a Company Order to the effect that such global Security shall be so exchangeable or (iv) an Event of Default has occurred and is continuing with respect to the Securities. If the beneficial owners of interests in a global Security are entitled to exchange such interests for definitive Securities as the result of an event described in clause (i), (ii), (iii) or (iv) of the preceding sentence, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities in such form and denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of such global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such global Security shall be surrendered from time to time by the U.S. Depository or such other Depository as shall be specified in the Company Order with respect thereto, and in accordance with instructions given to the Trustee and the U.S. Depository or such other Depository, as the case may be (which instructions shall be in writing but need not be contained in or accompanied by an Officers’ Certificate or be accompanied by an Opinion of Counsel), as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered global Security, a like aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such global Security to be exchanged; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of the same series to be redeemed and ending on the relevant Redemption Date. Promptly following any such exchange in part, such global Security shall be returned by the Trustee to such Depository or the U.S. Depository, as the case may be, or such other Depository or U.S. Depository referred to above in accordance with the instructions of the Company referred to above. If a Registered portion of a global Security after the close of business at the Office or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or Agency on the next Interest Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such global Security shall be payable in accordance with the provisions of this Indenture.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid and legally binding obligations of the Company evidencing the same debt and entitling the Holders thereof to the same benefits under this Indenture as the Securities surrendered upon such registration of transfer or exchange.

Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the Company or the Security Registrar for such Security) be duly endorsed, signature guaranteed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar for such Security duly executed by the Holder thereof, signature guaranteed, or his attorney duly authorized in writing.

23

No service charge shall be made for any registration of transfer or exchange, or redemption of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Sections 3.4, 3.6 and 11.7 not involving any transfer.

Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required (i) to issue, register the transfer of or exchange any Securities during a period beginning at the opening of business 15 days before the day of selection of Securities of like tenor and the same series under Section 11.3 for redemption and ending at the close of business on the day of such selection, (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except in the case of any Security to be redeemed in part, the portion thereof not to be redeemed; or (iii) to issue, register the transfer of or exchange any Security which, in accordance with its terms, has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid.

Section 3.6 Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security is surrendered to the Trustee, subject to the provisions of this Section 3.6, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding.

If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security, and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or to a Responsible Officer of the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and, upon the Company’s request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security, a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding.

Notwithstanding the foregoing provisions of this Section 3.6, in case any mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

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

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

24

The provisions of this Section, as amended or supplemented pursuant to this Indenture with respect to particular Securities or generally, shall be 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 3.7 Payment of Interest and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved.

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, and are punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more Predecessor Securities) is registered as of the close of business on the Regular Record Date for such interest.

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on such Registered Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when so deposited to be held in trust for the benefit of the Person entitled to such Defaulted Interest as in this clause provided. Thereupon, the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to the Holder of such Registered Security (or a Predecessor Security thereof) at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper of general circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

25

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

Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular series pursuant to the provisions of this Indenture, at the option of the Company, interest on Registered Securities that bear interest may be paid by wire transfer in immediately available funds if the holder of the Registered Security has provided to the Company and the Trustee wire instructions at least five business days prior to the applicable payment date or by check mailed to the address of that holder as it appears on the books of the Securities Registrar if that holder has not provided wire instructions; provided that the final distribution in respect of any Security will be made only upon presentation and surrender of such certificated debenture at the applicable Corporate Trust Office of the Trustee.

Subject to the foregoing provisions of this Section and Section 3.5, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

In the case of any Registered Security of any series that is convertible, which Registered Security is converted after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other than any Registered Security with respect to which the Stated Maturity is prior to such Interest Payment Date), interest with respect to which the Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Registered Security (or one or more predecessor Registered Securities) is registered at the close of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Registered Security which is converted, interest with respect to which the Stated Maturity is after the date of conversion of such Registered Security shall not be payable.

Section 3.8 Persons Deemed Owners.

Prior to due presentment of a Registered 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 Registered Security is registered in the Security Register as the owner of such Registered Security for the purpose of receiving payment of principal of, any premium and (subject to Section 3.5 and Section 3.7) interest on and any Additional Amounts with respect to such Registered Security and for all other purposes whatsoever, whether or not any payment with respect to such Registered Security shall be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary.

No Holder of any beneficial interest in any global Security held on its behalf by a Depository shall have any rights under this Indenture with respect to such global Security, and such Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the owner of such global Security for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

26

Section 3.9 Cancellation.

All Securities surrendered for payment, redemption, registration of transfer, exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities, as well as Securities surrendered directly to the Trustee for any such purpose, shall be cancelled promptly by the Trustee. 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 cancelled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by or pursuant to this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures.

Section 3.10 Computation of Interest.

Except as otherwise provided in or pursuant to this Indenture, or in any Security, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 3.11 CUSIP Numbers.

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

ARTICLE FOUR

and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose, money in the Currency in which such Securities are payable in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, including the principal of, any premium and interest on, and any Additional Amounts with respect to such Securities, to the date of such deposit (in the case of Securities which have become due and payable) or to the Maturity thereof, as the case may be;

(2) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the Outstanding Securities of such series; and

(3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been complied with.

Section 4.2 Defeasance and Covenant Defeasance.

28

(2) Upon the Company’s exercise of the above option applicable to this Section 4.2(2) with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities on the date the conditions set forth in clause (4) of this Section 4.2 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by such Outstanding Securities, which shall thereafter be deemed to be “Outstanding” only for the purposes of clause (6) of this Section 4.2 and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of such Outstanding Securities to receive, solely from the trust fund described in clause (4) of this Section 4.2 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect to, such Securities when such payments are due, and any rights of such Holder to convert or exchange such Securities into Common Stock or other securities, cash or other property, (ii) the obligations of the Company and the Trustee with respect to such Securities under Section 3.5, Section 3.6, Section 10.2 and Section 10.3 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 10.4 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 4.2(4)(a) below), and with respect to any rights to convert or exchange such Securities into Common Stock or other securities, cash or other property, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 4.2.

(3) Upon the Company’s exercise of the above option applicable to this Section 4.2(3) with respect to any Securities of or within a series, the Company shall be released from, to the extent specified pursuant to Section 3.1, any covenant applicable to such Securities, with respect to such Outstanding Securities on and after the date the conditions set forth in clause (4) of this Section 4.2 are satisfied (hereinafter, “covenant defeasance”), and such Securities shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with any such covenant, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities, the Company may omit to comply with, and shall have no liability in respect of, any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any covenant or by reason of reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a default or an Event of Default under Section 5.1(4) insofar as it relates to, to the extent specified pursuant to Section 3.1, any covenant applicable to such Security, or Section 5.1(7) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby.

in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.

(a) In the case of an election under clause (3) of this Section 4.2, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Outstanding

(2) default is made in the payment of any principal of or premium, if any, on, or any Additional Amounts payable in respect of any principal of or premium, if any, on any Security at its Maturity;

34

the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount of money then due and payable with respect to such Securities, with interest upon the overdue principal, any premium and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installments of interest and Additional Amounts at the rate or rates borne by or provided for in such Securities, and, in addition thereto, such further amount of money as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due to the Trustee under Section 6.7.

If the Company fails to pay the money it is required to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of the Trustee, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the money so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may and at the direction of the Holders of not less than 25% in principal amount of the Outstanding Securities of such series shall, so long as such Holders shall have provided the Trustee with such indemnity as it shall require, proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or such Securities or in aid of the exercise of any power granted herein or therein, or to enforce any other proper remedy.

(1) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of such series, of the principal and any premium, interest and Additional Amounts owing and unpaid in respect of the Securities 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 or counsel) and of the Holders of Securities allowed in such judicial proceeding, and

37

Section 5.11 Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to any Holder of a Security may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by such Holder, as the case may be.

Section 6.7 Compensation and Reimbursement.

The Company agrees:

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

(2) to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture arising out of or in connection with the acceptance or administration of the trust or trusts hereunder (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be caused by the Trustee’s own negligence or willful misconduct; and

When the Trustee incurs expenses or renders services after a Default or Event of Default specified in Section 5.1(5) and 5.1(6) hereof occurs, the expenses and the compensation for the services (including the fees and expense of its agents and counsel) are intended to constitute expense of administration under U.S. Code, Title 11 or any other similar foreign, federal or state law for the relief of debtors.

To the extent permitted by law any compensation or expense incurred by the Trustee after a default specified in or pursuant to Section 5.1 is intended to constitute an expense of administration under any then applicable bankruptcy or insolvency law. “Trustee” for purposes of this Section 6.7 shall include any predecessor Trustee but the negligence or willful misconduct of any Trustee shall not affect the rights of any other Trustee under this Section 6.7.

Notwithstanding any other provision of this Indenture to the contrary, in no event shall the Trustee be liable for special, indirect or consequential damages of any kind whatsoever (including but not limited to lost profits) even if the Trustee had been advised of the likelihood of such loss or damage and regardless of the form of action.

The provisions of this Section 6.7 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee and shall apply with equal force and effect to the Trustee in its capacity as Authenticating Agent, Paying Agent or Security Registrar.

Section 6.12 Appointment of Authenticating Agent.

The Trustee may appoint one or more Authenticating Agents acceptable to the Company with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of that or those series issued upon original issue, exchange, registration of transfer, partial redemption or partial repayment or pursuant to Section 3.6, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder.

Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Company may also from time to time designate one or more other Offices or Agencies where the Securities of one or more series 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 each Place of Payment for Securities of any series for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other Office or Agency.

Unless otherwise provided in or pursuant to this Indenture, the Company hereby designates as the Place of Payment for each series of Securities the Borough of Manhattan, The City of New York, and initially appoints a Corporate Trust Office of the Trustee located at 101

Unless otherwise specified with respect to any Securities pursuant to Section 3.1, if and so long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of this Indenture, then the Company will maintain with respect to each such series of Securities, or as so required, at least one exchange rate agent.

Section 10.3 Money for Securities Payments to Be Held in Trust.

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it shall, on or before each due date of the principal of, any premium or interest on or Additional Amounts with respect to any of the Securities of such series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents for any series of Securities, it shall, on or prior to each due date of the principal of, any premium or interest on or any Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a sum (in the currency or currencies, currency unit or units or composite currency or currencies described in the preceding paragraph) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

The Company shall cause each Paying Agent for any series of Securities (other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall:

(1) hold all sums held by it for the payment of the principal of, any premium or interest on or any Additional Amounts with respect to Securities of such series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as provided in or pursuant to this Indenture;

(2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of such series) in the making of any payment of principal, any premium or interest on or any Additional Amounts with respect to the Securities of such series; and

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same terms as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

55

Except as otherwise provided herein or pursuant hereto, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, any premium or interest on or any Additional Amounts with respect to any Security of any series and remaining unclaimed for two years after such principal or any such premium or interest or any such Additional Amounts shall have become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in an Authorized Newspaper in each Place of Payment for such series or to be mailed to Holders of Registered Securities of such series, or both, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing nor shall it be later than two years after such principal and any premium or interest or Additional Amounts shall have become due and payable, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 10.4 Additional Amounts.

If any Securities of a series provide for the payment of Additional Amounts, the Company agrees to pay to the Holder of any such Security Additional Amounts as provided in or pursuant to this Indenture or such Securities. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of such series established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms, and express mention of the payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

Except as otherwise provided in or pursuant to this Indenture or the Securities of the applicable series, if the Securities of a series provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to such series of Securities (or if the Securities of such series shall not bear interest prior to Maturity, the first day on which a payment of principal is made), and at least 10 days prior to each date of payment of principal or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers’ Certificate, the Company shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and premium, if any, or interest on the Securities of such series shall be made to Holders of Securities of such series who are United States Aliens (as demonstrated by delivery of appropriate tax forms) without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of such series. If any such withholding shall be required, then such Officers’ Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities, and the Company agrees to pay to the Trustee or such Paying

56

Agent the Additional Amounts required by the terms of such Securities. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished pursuant to this Section.

Section 10.5 Corporate Existence.

Subject to Article Eight, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and its rights (charter and statutory) and franchises; provided, however, that the foregoing shall not obligate the Company to preserve any such right or franchise if the Company shall determine that the preservation thereof is no longer desirable in the conduct of its business.

Section 10.6 Waiver of Certain Covenants.

The Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 10.3 and 10.5 with respect to the Securities of any series if before the time for such compliance the Holders of at least a 66-2/3% majority in principal amount of the Outstanding Securities of such series, by Act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

The election of the Company to optionally redeem any Securities shall be evidenced by or pursuant to a Board Resolution.

Section 11.3 Selection by Trustee of Securities to be Redeemed.

If less than all of the Securities of any series with the same issue date, interest rate or formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions of the principal amount of Registered Securities of such series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Registered Security of such series not redeemed to less than the minimum denomination for a Security of such series established herein or pursuant hereto.

The Trustee shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal of such Securities which has been or is to be redeemed.

Unless otherwise specified in or pursuant to this Indenture or the Securities of any series, if any Security selected for partial redemption is converted into or exchanged for Common Stock or other securities, cash or other property in part before termination of the conversion or

58

exchange right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption.

Section 11.4 Notice of Redemption.

Notice of redemption shall be given in the manner provided in Section 1.6, not less than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by mailing in the manner herein provided to the Holder of any Registered Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portion thereof.

Any notice that is mailed to the Holder of any Registered Securities in the manner herein provided shall be conclusively presumed to have been duly given, whether or not such Holder receives the notice.

All notices of redemption shall state:

(1) the Redemption Date,

(2) the Redemption Price,

(3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Security or Securities to be redeemed,

(4) in case any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder of such Security will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed,

(5) that, on the Redemption Date, the Redemption Price shall become due and payable upon each such Security or portion thereof to be redeemed, and, if applicable, that interest thereon shall cease to accrue on and after said date,

(6) the place or places where such Securities are to be surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts pertaining thereto,

A notice of redemption published as contemplated by Section 1.6 need not identify particular Registered Securities to be redeemed.

Section 11.5 Deposit of Redemption Price.

At or prior to 10:00 a.m., New York City time, on any Redemption Date, the Company shall deposit, with respect to the Securities of any series called for redemption pursuant to Section 11.4, with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3) an amount of money in the applicable Currency sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 3.1 or in the Securities of such series) any accrued interest on and Additional Amounts with respect thereto, all such Securities or portions thereof which are to be redeemed on that date.

Section 11.6 Securities Payable on Redemption Date.

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with any accrued interest and Additional Amounts to the Redemption Date; provided, however, that, except as otherwise specified in or pursuant to this Indenture or the Registered Securities of such series, installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the Regular Record Dates therefor according to their terms and the provisions of Section 3.7.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security.

Section 11.7 Securities Redeemed in Part.

Any Registered Security which is to be redeemed only in part shall be surrendered at any Office or Agency for such Security (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Registered Security or Securities of the same series, containing identical terms and provisions, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a Security in global form is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the U.S. Depository or other Depository for such Security in global form as shall be specified in the Company Order with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered.

Section 12.1 Applicability of Article.

The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise permitted or required in or pursuant to this Indenture or any Security of such series issued pursuant to this Indenture.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of such series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.2. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series and this Indenture.

Section 12.2 Satisfaction of Sinking Fund Payments with Securities.

The Company may, in satisfaction of all or any part of any sinking fund payment with respect to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver Outstanding Securities of such series (other than any of such Securities previously called for redemption or any of such Securities in respect of which cash shall have been released to the Company), and (2) apply as a credit Securities of such series which have been redeemed either at the election of the Company pursuant to the terms of such series of Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities of any series in lieu of cash payments pursuant to this Section 12.2, the principal amount of Securities of such series to be redeemed in order to satisfy the remaining sinking fund payment shall be less than $100,000, the Trustee need not call Securities of such series for redemption, except upon Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall at the request of the Company from time to time pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that series purchased by the Company having an unpaid principal amount equal to the cash payment requested to be released to the Company.

61

Section 12.3 Redemption of Securities for Sinking Fund.

Not less than 75 days prior to each sinking fund payment date for any series of Securities, the Company shall deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting of Securities of that series pursuant to Section 12.2, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not theretofore delivered. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not less than 60 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.3 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.4. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 11.6 and Section 11.7.

ARTICLE THIRTEEN

REPAYMENT AT THE OPTION OF HOLDERS

Section 13.1 Applicability of Article.

Securities of any series which are repayable at the option of the Holders thereof before their Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of Section 3.9, shall not operate as a payment, redemption or satisfaction of the Indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with a directive that such Securities be cancelled. Notwithstanding anything to the contrary contained in this Section 13.1, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the close of business on the repayment date an amount not less than the repayment price payable by the Company on repayment of such Securities, and the obligation of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers.

62

such reasonable basis of exchange and as of the record date with respect to Registered Securities of such series (if any) for such action, determination of rights or distribution (or, if there shall be no applicable record date, such other date reasonably proximate to the date of such action, determination of rights or distribution) as the Company may specify in a written notice to the Trustee or, in the absence of such written notice, as the Trustee may determine.

Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 1.4 or other proof.

(2) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders of Securities as provided in Section 15.2(2), in which case the Company or the Holders of Securities of the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting.

(3) At any meeting, each Holder of a Security of such series or proxy shall be entitled to one vote for each $1,000 principal amount of Securities of such series held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or proxy.

(4) Any meeting of Holders of Securities of any series duly called pursuant to Section 15.2 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting; and the meeting may be held as so adjourned without further notice.

Section 15.6 Counting Votes and Recording Action of Meetings.

The vote upon any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities of such series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the permanent secretary of the meeting their verified written reports in triplicate of all votes cast at the meeting. A record, at least in triplicate, of the proceedings of each meeting of Holders of Securities of any series shall be prepared by the permanent secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was given as provided in Section 15.2 and, if applicable, Section 15.4. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

ARTICLE 2

THE SECURITIES

Section 2.01. Form and Dating. (a) The Securities and the corresponding Trustee’s certificate of authentication shall be substantially in the respective forms set forth in Exhibit A, which Exhibit is incorporated in and made part of this First Supplemental Indenture. The Securities may have notations, legends or endorsements required by law, exchange rule, Applicable Procedures or usage. The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication.

The terms and provisions contained in the Securities shall constitute, and are hereby expressly made, a part of this First Supplemental Indenture and the Company and the Trustee, by their execution and delivery of this First Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby; provided, however, to the extent permitted by applicable law, if any provision of any Security conflicts with the express provisions of this First Supplemental Indenture, the provisions of this First Supplemental Indenture shall govern and be controlling.

(b) Global Securities. All of the Securities shall be issued initially in the form of one or more Global Securities, which shall be deposited on behalf of the purchasers of the Securities represented thereby with the Securities Custodian, as custodian for the depositary, The Depository Trust Company (such depositary, or any successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co., or as otherwise instructed by the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the Global Securities may from time to time be increased or decreased by adjustments made on the records of the Securities Custodian and the Depositary as hereinafter provided, subject in each case to compliance with the Applicable Procedures and the provisions of this First Supplemental Indenture.

(c) Global Securities In General. Each Global Security shall represent such of the outstanding Securities as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, purchases or conversions of such Securities, in each case in accordance with this First Supplemental Indenture. Any adjustment of the aggregate principal amount of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding Securities represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 3.5 of the Base Indenture, or otherwise in accordance with this First Supplemental Indenture, and shall be made on the records of the Trustee and the Depositary.

The Company shall issue and the Trustee shall, upon receipt of a Company Order, authenticate and deliver in accordance with Section 2.02, initially one or more Global Securities that (i) shall be registered in the name of Cede & Co. or as otherwise instructed by the Depositary, (i) shall be delivered by the Trustee to the Depositary or to the Securities Custodian pursuant to the Depositary’s instructions and (ii) shall bear legends required for Global Securities as set forth in Exhibit A hereto.

10

(d) Book Entry Provisions. Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this First Supplemental Indenture with respect to any Global Security held on their behalf by the Depositary or under the Global Security, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (A) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary, or such nominee, as the case may be, or (B) impair, as between the Depositary and its Agent Members, the Applicable Procedures or the operation of customary practices governing the exercise of the rights of a Holder of any Security.

None of the Company, the Trustee, the Registrar, any Paying Agent or any agent of any of them shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Securities, for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any acts or omissions of a Depositary or for any transactions between a Depositary and any beneficial owner or between or among beneficial owners. No owner of a beneficial interest in the Securities shall have any rights under this First Supplemental Indenture, and the Depositary or its nominee, if any, shall be deemed and treated by the Company, the Trustee, the Registrar, any Paying Agent or any agent of any of them as the absolute owner and holder of such Securities for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, the Registrar, any Paying Agent or any agent of any of them from giving effect to any written certification, proxy or other authorization furnished by a Depositary, or any of its members and any other Person on whose behalf such member may act.

Section 2.02. Authentication. (a) The Trustee shall initially authenticate and make available for delivery Securities for original issue in the aggregate principal amount of up to $55,000,000 (which includes $5,000,000 aggregate principal amount pursuant to the Underwriter’s exercise of its over-allotment option in full) upon receipt of a Company Order. The Company may, without the consent of the Holders, re-open the Securities and issue additional Securities (the “Additional Securities”) with the same terms and with the same CUSIP number as the Securities in an unlimited aggregate principal amount; provided, however that no such Additional Securities may be issued unless fungible with the Securities offered hereby for U.S. federal income tax purposes. The Trustee shall authenticate Additional Securities thereafter in unlimited aggregate principal amount (so long as permitted by the terms of this First Supplemental Indenture) for original issue upon a Company Order in aggregate principal amount as specified in such order (except as provided in Section 3.6 of the Base Indenture). Each such Company Order shall specify the amount of Securities to be authenticated and the date on which the Securities are to be authenticated. Such Additional Securities shall have identical terms to the Initial Securities except for adjustments for any differences in issuance dates and prices and with respect to interest accruing prior to their date of issuance, and will constitute the same series as the Initial Securities for all purposes hereunder, including, without limitation, waivers, amendments and offers to purchase.

11

(b) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in the Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company.

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

Section 2.03. Registrar, Paying Agent and Conversion Agent. 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 in the United States where Securities may be presented for purchase 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 First Supplemental Indenture may be served. The Registrar shall keep a register of the Securities (“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 “Registrar” includes any co-registrar, the term “Paying Agent” includes any additional paying agent and the term “Conversion Agent” includes any additional conversion agent, including any named pursuant to Section 10.2 of the Base Indenture.

The Company shall enter into an appropriate agency agreement with any Agent not a party to this First Supplemental Indenture. The agreement shall implement the provisions of this First Supplemental Indenture that relate to such Agent. The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this First Supplemental Indenture. If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent or agent for service of notices and demands in any place required by this First Supplemental Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent.

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

Section 2.04. Paying Agent to Hold Money and Securities in Trust. Prior to 11:00 a.m., New York City time, on each due date of payments in respect of, or delivery of Cash or shares of Common Stock, as applicable and as provided herein, the Company shall deposit with the Paying Agent Cash (in immediately available funds if deposited on the due date) or with the Conversion Agent such number of shares of Common Stock or other consideration sufficient to make such payments or deliveries when so becoming due. The Company shall require each Paying Agent or Conversion Agent, as applicable (other than the Trustee), to agree in writing that such Agent shall hold in trust for the benefit of Holders or the Trustee all Cash, Common Stock or other consideration, as applicable, held by such Agent for the making of payments or deliveries in respect of the Securities and shall notify the Trustee in writing of any default by the Company in

12

making any such payment or delivery. If the Company or an Affiliate of the Company acts as Paying Agent or Conversion Agent, as applicable, it shall segregate the Cash, Common Stock and other consideration, as applicable, held by it as Paying Agent or Conversion Agent, as applicable, and hold it as a separate trust fund.

The Company at any time may require the Paying Agent or Conversion Agent, as applicable, to pay all Cash, Common Stock or other consideration, as applicable, held by it to the Trustee, and the Trustee may at any time during the continuance of any Default, upon written request to the Paying Agent or the Conversion Agent, as applicable, require such Paying Agent or Conversion Agent, as applicable, to pay forthwith to the Trustee all Cash, Common Stock or other consideration, as applicable, so held in trust by such Paying Agent or Conversion Agent. Upon doing so, the Paying Agent or the Conversion Agent, as applicable, shall have no further liability for such Cash, Common Stock or other consideration, as applicable.

Section 2.05. 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 the Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee on or before each Interest Payment Date, and at such other times as the Trustee may request in writing, a list of the names and addresses of the Holders in such form and as of such date as the Trustee may reasonably request.

Section 2.06. Transfer and Exchange. (a) Subject to compliance with any applicable additional requirements contained in Section 3.5 of the Base Indenture, when a Security is presented to a 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, if such Security is a Registered Security, be duly endorsed or accompanied by an assignment form, in the form included in Exhibit A attached hereto and, if applicable, a transfer certificate, in the form included in Exhibit A attached hereto, and in form reasonably satisfactory to the Registrar 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 pursuant to Section 2.03, the Company shall execute and the Trustee shall, upon receipt of a Company Order, authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto, other than exchanges pursuant to Section 3.9 of the Base Indenture or Section 9.05, Article 3 or Article 4 of this First Supplemental Indenture, in each case, not involving any transfer.

Neither the Company, any Registrar nor the Trustee shall be required to exchange or register a transfer of any Securities or portions thereof in respect of which a Fundamental Change Purchase Notice has been delivered and not validly withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the portion thereof not to be purchased).

13

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 First Supplemental Indenture as the Securities surrendered upon such transfer or exchange.

(b) Any Registrar appointed pursuant to Section 2.03 of this First Supplemental Indenture or Section 10.2 of the Base Indenture shall provide to the Trustee such information as the Trustee may reasonably request in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this First Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or other beneficial owners of interests in any Global Security) other than to require delivery of such opinions of counsel, 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 First Supplemental Indenture (including if so requested by the Company exercising a right to require the delivery of such items), and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Any Holder of a Global Security shall, by acceptance of such Global Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by the Depositary (or its agent), and that ownership of a beneficial interest in a Global Security shall be required to be reflected in a book-entry system.

Section 2.07. Cancellation. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article 4.

All Securities that are purchased pursuant to Article 3 or otherwise acquired by the Company shall be delivered to the Trustee for cancellation. If the Company shall acquire any of the Securities, such acquisition shall not operate as a repurchase or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation.

Section 2.08. Ranking. The obligations of the Company arising under or in connection with this First Supplemental Indenture and every outstanding Security issued under this First Supplemental Indenture from time to time constitute and shall constitute an unsecured general obligation of the Company, ranking equal in right of payment to all senior indebtedness and senior in right of payment to all subordinated debt.

Section 2.09. 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, which shall initially be the Depositary, as the owner of such Security for the purpose of receiving payment of principal of, Fundamental Change Purchase Price and interest on the Security, for the purpose of receiving Common Stock or Cash and for all other purposes, including without limitation, for purposes of giving notices hereunder, whatsoever, whether or not such Security is overdue, and none of the

14

Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. The registered Holder of a Global Security may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this First Supplemental Indenture or the Securities.

ARTICLE 3

REPURCHASE OF SECURITIES AT OPTION OF HOLDERS

Section 3.01. Purchase of Securities at Option of the Holder upon a Fundamental Change. (a) In the event a Fundamental Change shall occur at any time when any Securities remain outstanding, each Holder shall have the right, at such Holder’s option, to require the Company to purchase all of such Holders’ Securities or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple thereof on a date specified by the Company (the “Fundamental Change Purchase Date”) that is not less than 15 nor more than 30 Business Days after the date the Company mails the Fundamental Change Company Notice pursuant to Section 3.01(b), at a purchase price in Cash equal to 100% of the principal amount of the Securities tendered for purchase, plus accrued and unpaid interest (including any Additional Interest) to, but not including, the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”), subject to satisfaction by or on behalf of any Holder of the requirements set forth in Section 3.01(c). No Securities may be purchased at the option of the Holders upon a Fundamental Change if there has occurred and is continuing an Event of Default other than an Event of Default that is cured by the payment of the Fundamental Change Purchase Price of the Securities.

A “Fundamental Change” shall be deemed to have occurred upon the occurrence of any of the following:

(i) a “person” or “group” within the meaning of Section 13(d)(3) of the Exchange Act becomes the direct or indirect “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of shares of the Common Stock representing more than 50% of the voting power of the Common Stock entitled to vote generally in the election of directors and (A) files a Schedule 13D or Schedule TO or any other schedule, form or report under the Exchange Act disclosing such beneficial ownership or (B) the Company otherwise becomes aware of any such person or group; or

(ii) the Common Stock into which the Securities are then convertible ceases to be listed for trading on the NYSE, Nasdaq or another national securities exchange and is not then quoted on an established automated over-the-counter trading market in the United States;

(iii) the first day on which a majority of the members of the Company’s board of directors does not consist of continuing directors; or

15

(iv) a consolidation, merger or binding share exchange, or any conveyance, transfer, sale, lease or other disposition in a single transaction or a series of transactions of all or substantially all of the Company’s properties and assets other than:

(A) any transaction:

(1) that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of the Company’s capital stock; and

(2) pursuant to which holders of the Company’s capital stock immediately prior to the transaction have the entitlement to exercise, directly or indirectly, 50% or more of the total voting power of all shares of capital stock entitled to vote generally in elections of directors of the continuing or surviving or successor Person immediately after giving effect to such transaction in substantially the same proportion as their entitlement to exercise, directly or indirectly, voting power of shares of the Company’s capital stock entitled to vote generally in elections of the Company’s directors immediately prior to such transaction; or

(B) any transaction that is effected solely for the purpose of changing the Company’s jurisdiction of incorporation and resulting in a reclassification, conversion or exchange of outstanding shares of Common Stock, if at all, solely into shares of common stock of the surviving entity or a direct or indirect parent of the surviving corporation.

(v) the Company’s shareholders approve any plan or proposal for the Company’s liquidation or dissolution.

A “Make-Whole Fundamental Change” shall be deemed to have occurred upon the occurrence of a Fundamental Change described in clauses (i), (ii), (iv) or (v) above.

For purposes of this Section 3.01:

(I) “board of directors” means the board of directors or other governing body charged with the ultimate management of any person;

(II) “continuing director” means a director who either was a member of the Company’s board of directors on the date of the Prospectus, or who becomes a member of the board of directors subsequent to that date and whose election, appointment or nomination for election by the Company’s shareholders is duly approved by a majority of the continuing directors on the Company’s board of directors at the time of such approval, either by a specific vote or by approval of the proxy statement issued by the Company on behalf of the Company’s entire board of directors in which such individual is named as a nominee for director; and

16

(III) “person” includes any syndicate or group that would be deemed to be a “person” under Section 13(d)(3) of the Exchange Act.

(b) Notices of Fundamental Change.

(i) Within 10 days after the public announcement of any event constituting a Fundamental Change, the Company shall notify the Trustee in writing of such event and shall mail a written notice of the Fundamental Change to each Holder (and to beneficial owners as required by applicable law) in accordance with Section 1.04. The notice shall state:

(A) the events causing such Fundamental Change, the Adjustment Date of the Fundamental Change (in the case of a Make-Whole Fundamental Change) and the anticipated date of effectiveness of such Fundamental Change;

(B) that the Holder will have a right to require the Company to purchase the Holder’s Securities if such Fundamental Change is consummated; and

(C) in the case of a Make-Whole Fundamental Change, that no Additional Shares will be added to the Conversion Rate if the Make-Whole Fundamental Change is not consummated and that payment of any Additional Shares associated with Securities surrendered for conversion in connection with such Make-Whole Fundamental Change will occur no earlier than the date of effectiveness of such Make-Whole Fundamental Change.

(ii) Within 10 days after the effective date of each Fundamental Change, the Company shall notify the Trustee in writing of the Fundamental Change Purchase Date and shall mail a written notice of the Fundamental Change (each such notice a “Fundamental Change Company Notice”) to each Holder (and to beneficial owners as required by applicable law) in accordance with Section 1.04. The notice shall include the form of a Fundamental Change Purchase Notice to be completed by the Holder and shall state, as applicable:

(A) the events causing such Fundamental Change, the adjustment date of the Fundamental Change (in the case of a Make-Whole Fundamental Change) and the date of effectiveness of such Fundamental Change;

(H) that the Securities must be surrendered to the Paying Agent to collect payment of the Fundamental Change Purchase Price;

(I) that the Fundamental Change Purchase Price for any Security as to which a Fundamental Change Purchase Notice has been duly given and not withdrawn shall be paid promptly following the later of the Fundamental Change Purchase Date and the time of surrender of such Security;

(J) the Conversion Rate (after giving effect to any change in the Conversion Rate that resulted from the Fundamental Change);

(K) that the Securities with respect to which a Fundamental Change Purchase Notice has been given may be converted pursuant to Article 4 of this First Supplemental Indenture only if either (i) the Fundamental Change Purchase Notice has been withdrawn in accordance with the terms of this First Supplemental Indenture or (ii) there shall be a default in the payment of the Fundamental Change Purchase Price;

(L) the procedures for withdrawing a Fundamental Change Purchase Notice;

(M) that, unless the Company defaults in making payment of such Fundamental Change Purchase Price, interest on Securities surrendered for purchase by the Company shall cease to accrue on and after the Fundamental Change Purchase Date; and

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

If any of the Securities are in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the Applicable Procedures for repurchases.

At the Company’s request, the Trustee shall give the Fundamental Change Company Notice on behalf of the Company and at the Company’s expense; provided, however, that the Company makes such request at least three Business Days (unless a shorter period shall be consented to by the Trustee) prior to the date by which such Fundamental Change Company Notice must be given to the Holders in accordance with this Section 3.01(b); provided, further, however, that the text of such notice shall be prepared by the Company.

(c) Fundamental Change Purchase Notice. A Holder may exercise its right specified in Section 3.01(a) upon delivery of a written notice (which shall be in substantially the form included in Exhibit A hereto and which may be delivered by letter, overnight courier, hand

18

delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Applicable Procedures) of the exercise of such rights (a “Fundamental Change Purchase Notice”) to and such Fundamental Change Purchase Notice must be received by the Paying Agent no later than the Close of Business on the Business Day immediately preceding the Fundamental Change Purchase Date. The Fundamental Change Purchase Notice must state:

(i) if Registered Securities are to be delivered, the certificate numbers of the Securities that the Holder shall deliver to be purchased;

(ii) the portion of the principal amount of the Securities that the Holder shall deliver to be purchased, which portion must be in principal amounts of $1,000 or an integral multiple thereof; and

(iii) that such Securities are being tendered for and shall be purchased by the Company on the Fundamental Change Purchase Date pursuant to the terms and conditions specified in this First Supplemental Indenture.

The book-entry transfer or delivery of such Security to the Paying Agent (together with all necessary endorsements) at the office of the Paying Agent shall be a condition to the receipt by the Holder of the Fundamental Change Purchase Price; provided, however, that such Fundamental Change Purchase Price shall be paid pursuant to this Section 3.01 only if the Security so transferred by book-entry or delivered to the Paying Agent shall conform in all material respects to the description thereof in the related Fundamental Change Purchase Notice.

The Company shall purchase from the Holder thereof, pursuant to this Section 3.01, a portion of a Security if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Section 3.01 that apply to the purchase of all of a Security also apply to the purchase of such a portion of such Security.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 3.01(c) shall have the right to withdraw such Fundamental Change Purchase Notice at any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.02(b).

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notices or written notices of withdrawal thereof.

(d) Notwithstanding anything herein to the contrary, in the case of Global Securities, any Fundamental Change Purchase Notice may be delivered or withdrawn, and such Securities may be surrendered or transferred by book-entry or delivered for purchase, in accordance with the Applicable Procedures.

Section 3.02. Effect of Fundamental Change Purchase Notice. (a) Upon receipt by the Paying Agent of a Fundamental Change Purchase Notice, the Holder of the Security in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental

19

Change Purchase Notice is withdrawn as specified below) thereafter be entitled to receive the Fundamental Change Purchase Price with respect to such Security. Such Fundamental Change Purchase Price shall be paid to such Holder promptly following the later of (i) the Fundamental Change Purchase Date (provided such Holder has satisfied the conditions in Section 3.01(c) with respect to such Security) and (ii) the time of book-entry transfer or delivery of such Security to the Paying Agent by the Holder thereof in the manner required by Section 3.01(c). A Security in respect of which a Fundamental Change Purchase Notice has been given by the Holder thereof may not be converted pursuant to Article 4 hereof on or after the date of the delivery of such Fundamental Change Purchase Notice, unless either (i) such Fundamental Change Purchase Notice has first been validly withdrawn in accordance with Section 3.02(b); or (ii) there shall be a default in the payment of the Fundamental Change Purchase Price, provided, that the conversion right with respect to such Security shall terminate at the Close of Business on the date such default is cured and such Security is purchased in accordance herewith.

(b) A Fundamental Change Purchase Notice may be withdrawn by any Holder delivering such Fundamental Change Purchase Notice upon delivery of a written notice of withdrawal (which may be delivered by mail, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Applicable Procedures) to and such notice of withdrawal must be received by the Paying Agent at any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Purchase Date, specifying:

(i) if Registered Securities are to be withdrawn, the certificate numbers of the Securities in respect of which such notice of withdrawal is being submitted;

(ii) the principal amount of the Securities in respect of which such notice of withdrawal is being submitted, which principal amount must be $1,000 or an integral multiple thereof; and

(iii) the principal amount, if any, of the Securities that remains subject to the original Fundamental Change Purchase Notice and that has been or shall be delivered for purchase by the Company.

Section 3.03. Deposit of Fundamental Change Purchase Price. Prior to 11:00 a.m., New York City time, on a Fundamental Change Purchase Date, the Company shall deposit with the Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an amount in Cash (in immediately available funds if deposited on such Fundamental Change Purchase Date) sufficient to pay the aggregate Fundamental Change Purchase Price of all the Securities or portions thereof that are to be purchased on that Fundamental Change Purchase Date.

If the Paying Agent holds, in accordance with the terms hereof, at 11:00 a.m., New York City time, on the Business Day following a Fundamental Change Purchase Date, Cash sufficient to pay the aggregate Fundamental Change Purchase Price of all Securities for which a Fundamental Change Purchase Notice has been delivered and not validly withdrawn in accordance with this First Supplemental Indenture, then, on and after such Fundamental Change

20

Purchase Date, such Securities shall cease to be outstanding and interest (including Additional Interest) on such Securities shall cease to accrue, whether or not such Securities are transferred by book-entry or delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery of such Securities by their Holders to the Paying Agent).

Section 3.04. Securities Purchased in Part. Any Registered 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 reasonably 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 a Fundamental Change Purchase Date, the Company shall issue and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly), authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of such 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.

Section 3.05. Repayment to the Company. To the extent that the aggregate amount of Cash deposited by the Company pursuant to Section 3.03 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof that the Company is obligated to purchase on the Fundamental Change Purchase Date, then, within one day after the Fundamental Change Purchase Date, the Paying Agent shall return any such excess Cash to the Company.

Section 3.06. Compliance with Securities Laws upon Purchase of Securities. When complying with the provisions of Article 3 hereof (provided that such offer or purchase constitutes an “issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), and subject to any exemptions available under applicable law, the Company shall:

(a) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable; and

(b) otherwise comply with all federal and state securities laws so as to permit the rights and obligations in connection with any purchase pursuant to this Article 3 to be exercised in the time and in the manner specified herein.

ARTICLE 4

CONVERSION

Section 4.01. Conversion Privilege. The Securities shall be convertible in accordance with their terms and in accordance with and subject to this Article 4 into a number of shares of Common Stock equal to the Conversion Rate, subject to the provisions of Section 4.02 regarding fractional shares, at any time prior to the Close of Business on the Business Day immediately preceding the Maturity Date. Securities may be converted only in denominations of $1,000 principal amount and integral multiples thereof.

21

Section 4.02. Conversion Rate. (a) The initial Conversion Rate per $1,000 principal amount of Securities to be converted is 76.7448 shares (which is equal to an initial Conversion Price of $13.03 per share), subject to adjustment as described in Section 4.06. The Conversion Rate, including any Additional Shares added to the Conversion Rate in connection with a Make-Whole Fundamental Change, will not exceed 20.7211 shares (which is equal to a Conversion Price of $10.26 per share); provided, however, that such maximum conversion rate will be appropriately adjusted for Conversion Rate adjustments as described in Section 4.06.

A Holder of a Security otherwise entitled to a fractional share will receive cash in an amount equal to the average of the Closing Prices of the Common Stock for the five consecutive Trading Day period ending on the Trading Day prior to the Conversion Date.

A Security for which a Holder has delivered a Fundamental Change Purchase Notice requiring the Company to purchase the Securities may be surrendered for conversion only if such notice is withdrawn in accordance with this First Supplemental Indenture.

(b) If a Holder elects to convert Securities in connection with a Make-Whole Fundamental Change, then the Conversion Rate of the Securities being converted by such Holder shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) set forth in Exhibit B. For the avoidance of doubt, the increases provided for in this Section 4.02(b) shall only be made with respect to the Securities being converted in connection with such Make-Whole Fundamental Change and shall not be effective as to any Securities not so converted. For purposes of this Section 4.02, a conversion shall be deemed to be “in connection” with a Make-Whole Fundamental Change if it occurs during the period that begins on (and includes) the public announcement of an event constituting a Make-Whole Fundamental Change and ends on (and includes) the Fundamental Change Purchase Date relating to such Make-Whole Fundamental Change as set forth in Article 3.

The increase in the Conversion Rate, expressed as a number of Additional Shares to be received per $1,000 principal amount of Securities, will be determined by the Company by reference to the table attached as Exhibit B hereto, based on the earliest of the date on which the Make-Whole Fundamental Change is publicly announced, occurs or becomes effective (the “Adjustment Date”) and the price paid or deemed to be paid per share of Common Stock in the transaction constituting the Make-Whole Fundamental Change (the “Stock Price”) subject to adjustment as set forth in the next paragraph; provided, however, that if a Holder of the Common Stock receives only Cash in connection with such transaction, the Stock Price shall be the Cash amount paid per share. In all other cases, the Stock Price will be the average of the Closing Prices of the Common Stock over the five consecutive Trading Days prior to but not including the date of effectiveness of the Make-Whole Fundamental Change, provided, however, that (i) if the Stock Price is between two Stock Price amounts on the table or the Adjustment Date is between two Adjustment Dates on the table, the number of Additional Shares will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the earlier and later adjustment dates based on a 365-day year, as applicable; (ii) if the Stock Price is in excess of $80.00 per share (subject to adjustment in the same manner as the Stock Price), no increase in the Conversion Rate will be made; and (iii) if the Stock Price is less than $10.26 per share (subject to adjustment as set forth in the next paragraph), no increase in the Conversion Rate will be made. Notwithstanding the foregoing, in

22

no event will the total number of Additional Shares added to the Conversion Rate as a result of such Make-Whole Fundamental Change exceed 20.7211 shares per $1,000 principal amount of notes, subject to adjustment as described in Section 4.06.

The Stock Prices set forth in the first columns of the table attached as Exhibit B hereto will be adjusted as of any date on which the Conversion Rate is adjusted as described in Section 4.06. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares will be adjusted in the same manner as the Conversion Rate as set forth in Section 4.06.

If, as set forth in this Section 4.06(b), the Company is required to increase the Conversion Rate by the Additional Shares as a result of a Make-Whole Fundamental Change, payment of such Additional Shares associated with Securities surrendered for conversion in connection with a Make-Whole Fundamental Change will be settled as follows:

• if the Conversion Date occurs prior to the date of effectiveness of such Make-Whole Fundamental Change, settlement shall occur no later than the third Trading Day immediately following such date of effectiveness; and

• if the Conversion Date occurs on or following the date of effectiveness of such Make-Whole Fundamental Change, settlement shall occur no later than the third Trading Day immediately following such Conversion Date.

The Company will settle such conversions by delivering Reference Property equivalent to shares of the Common Stock based on the increased Conversion Rate resulting from such Make-Whole Fundamental Change.

For the avoidance of doubt, in the event Securities are surrendered for conversion in connection with an anticipated Make-Whole Fundamental Change and such Make-Whole Fundamental Change does not in fact occur, no Additional Shares will be added to the Conversion Rate and no additional Cash or Reference Property will be paid as a result of the related anticipated Make-Whole Fundamental Change.

Section 4.03. Conversion Procedure. (a) The right of conversion attaching to any Security may be exercised at any time during which conversion is permitted in accordance with Section 4.01 (i)(i) if such Security is represented by a Global Security, by book-entry transfer to the Conversion Agent through the facilities of the Depositary in accordance with the Applicable Procedures, or (ii) if such Security is represented by a Registered Security, by delivery of such Security at the specified office of the Conversion Agent, accompanied, in either case, by: (1) a duly signed and completed conversion notice, in the form as set forth on the reverse of Security attached hereto as Exhibit A (a “Conversion Notice”); (2) if such Registered Security has been lost, stolen, destroyed or mutilated, a notice to the Conversion Agent in accordance with Section 3.6 of the Base Indenture regarding the loss, theft, destruction or mutilation of the Security; (3) appropriate endorsements and transfer documents if required by the Conversion Agent; and (4) payment of any tax or duty, in accordance with Section 4.04, which may be

23

payable in respect of any transfer involving the issue or delivery of the Common Stock in the name of a Person other than the Holder of the Security. The date on which the Holder satisfies all of those requirements is the “Conversion Date.” The Securities will be deemed to be converted immediately prior to the Close of Business on the Conversion Date. The Company shall deliver the shares to the Holder through a Conversion Agent in the form of a certificate for the number of whole shares of Common Stock issuable upon the conversion or, in the case of holders of Securities in book-entry form with DTC, in accordance with DTC customary practices. In each case, the Company shall also deliver to such holder Cash in lieu of any fractional shares pursuant to Section 4.02(a). The Company shall deliver such shares and Cash as promptly as practicable after the Conversion Date and the completion of the relevant calculations relating to the conversion considerations and, except as set forth in Section 4.02(b), in any event no later than the third Trading Day immediately following the Conversion Date.

(b) The person in whose name the Security is registered shall be deemed to be a shareholder of record on the Conversion Date; provided, however, that no surrender of a Security or satisfaction of the other conditions in Section 4.03(a) on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall, provided that all such conditions have been satisfied, be effective to constitute the person or persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the Close of Business on the next succeeding day on which such stock transfer books are open. Upon conversion of a Security, such person shall no longer be a Holder of such Security.

(c) The Company’s delivery to the Holder of the full number of shares of Common Stock into which the Security is convertible, together with any Cash payment for such holder’s fractional shares, will be deemed to satisfy the Company’s obligation to pay the principal amount of the Security and to satisfy the Company’s obligation to pay accrued and unpaid interest (including any Additional Interest) to but not including the Conversion Date. As a result, accrued interest is deemed paid in full rather than cancelled, extinguished or forfeited.

(d) Upon surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall, upon receipt of a Company Order, authenticate and deliver to the Holder, a new Security equal in principal amount of the unconverted portion of the Security surrendered.

Section 4.04. Taxes on Conversion. If a Holder converts a Security, the Company shall pay any documentary, stamp or similar issue or transfer taxes or duties relating to the issuance or delivery of shares of Common Stock upon exercise of such conversion rights. However, the Holder shall pay any tax or duty which may be payable relating to any transfer involving the issuance or delivery of shares of Common Stock in a name other than the Holder’s name. The Conversion Agent may, without obligation, refuse to deliver the certificate representing shares of Common Stock being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax or duties which will be due because the shares are to be issued in a name other than the Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation.

24

Section 4.05. Company to Provide Stock. (a) The Company shall, prior to the issuance of any Securities hereunder, and from time to time as may be necessary, reserve at all times and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock deliverable upon conversion of all of the Securities.

(b) All shares of Common Stock that may be issued upon conversion of the Securities shall be newly issued shares or shares held in the treasury of the Company, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free of any preemptive rights and free of any lien or adverse claim.

(c) The Company shall comply with all applicable securities laws regulating the offer and delivery of any Common Stock upon conversion of Securities and, if the Common Stock is then listed or quoted on the NYSE, Nasdaq or any other United States national or regional securities exchange or other market, shall list or cause to have quoted and keep listed and quoted the shares of Common Stock issuable upon conversion of the Securities to the extent permitted or required by the rules of such exchange or market; provided, however, that, if the rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the first conversion of the Securities into Common Stock in accordance with the provisions of this First Supplemental Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Securities in accordance with the requirements of such automated quotation system or exchange at such time.

(d) Notwithstanding anything herein to the contrary, nothing herein shall give to any Holder any rights as a creditor in respect solely of its right to conversion.

Section 4.06. Adjustment of Conversion Rate. This Section 4.06 describes adjustments to the Conversion Rate to be made in connection with the events described below, as well as events that will not result in adjustment of the Conversion Rate, treatment of rights and treatment of Reference Property. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occur, except that the Company will not make any adjustment if Holders of Securities may participate, as a result of holding the Securities, in the transactions described without having to convert their Securities:

(a) If the Company, at any time or from time to time while any of the Securities are outstanding, issues shares of Common Stock as a dividend or distribution on shares of Common Stock, or if the Company effects a share split or share combination in respect of the Common Stock, then the Conversion Rate shall be adjusted based on the following formula:

25

where

CR0	=	the Conversion Rate in effect immediately prior to the Ex Date of such dividend or distribution, or effective date of such share split or combination, as applicable;
CR'	=	the Conversion Rate in effect on and after the Ex Date or effective date;
OS0	=	the number of shares of Common Stock outstanding immediately prior to the Ex Date or effective date; and
OS'	=	the number of shares of Common Stock outstanding on and after the Ex Date or effective date.

Such adjustment shall become effective immediately after 9:00 a.m., New York City time, on the Business Day following the Ex Date of such dividend or distribution or the effective date of such share split or share combination. The Company will not pay any dividend or make any distribution on shares of Common Stock held in treasury by the Company. If any dividend or distribution of the type described in this Section 4.06(a) is declared but not so paid or made, or the outstanding shares of Common Stock are not split or combined, as the case may be, the Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect if such dividend, distribution, share split or share combination had not been declared.

(b) If the Company, at any time or from time to time while any of the Securities are outstanding, issues to all holders of its outstanding shares of Common Stock any rights or warrants (other than pursuant to any dividend reinvestment or share purchase plans) entitling them for a period of not more than 45 days from the issuance date thereof to subscribe for or purchase shares of Common Stock at a price per share less than the average of the Closing Prices of the Common Stock over the five consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be adjusted based on the following formula:

where

CR0	=	the Conversion Rate in effect immediately prior to the Ex Date for such issuance;
CR'	=	the Conversion Rate in effect on and after the Ex Date for such issuance;
OS0	=	the number of shares of Common Stock outstanding immediately prior to the Ex Date for such issuance;
X	=	the total number of shares of Common Stock issuable pursuant to such rights or warrants; and
Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average of the Closing Prices of the Common Stock over the five consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of the issuance of such rights or warrants.

26

Such adjustment shall be successively made whenever any such rights or warrants are issued and shall become effective immediately after 9:00 a.m., New York City time, on the Business Day following the Ex Date of such issuance. To the extent that 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 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 announcement with respect to such rights, warrants or convertible securities had not been made.

In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than the average of the Closing Prices of the Common Stock over the five consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate price payable to exercise such rights or warrants, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable on exercise thereof, the value of such consideration, if other than Cash, to be determined in good faith by the Company’s Board of Directors.

(c) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company (other than Common Stock as covered by Section 4.06(a)), evidences of its Indebtedness or other non-cash assets (including shares of capital stock or similar equity interest in or relating to a subsidiary or other business unit), or rights or warrants, but excluding (i) dividends, distributions and rights or warrants covered by Section 4.06(a), Section 4.06(b) or Section 4.06(e) (in each case pursuant to which an adjustment is made) and (ii)to the extent provided in Section 4.08, rights distributed pursuant to a shareholder rights agreement (any of such shares of capital stock, Indebtedness, or other assets or property hereinafter in this Section 4.06(c) called the “Distributed Property”), then, in each such case the Conversion Rate shall be adjusted based on the following formula:

where

CR0	=	the Conversion Rate in effect immediately prior to the Ex Date for such distribution;
CR’	=	the Conversion Rate in effect on and after the Ex Date for such distribution;

27

SP0	=	the average of the Closing Prices of the Common Stock over the five consecutive Trading Day period ending on the Trading Day immediately preceding the Ex Date for such distribution; and
FMV	=	the fair market value (as determined in good faith by the Company’s Board of Directors) of the portion of Distributed Property with respect to each outstanding share of Common Stock on the Ex Date for such distribution.

Such adjustment shall become effective immediately prior to 9:00 a.m., New York City time, on the Business Day following the Ex Date; provided that if the then fair market value (as so determined) of the portion of the Distributed Property so distributed applicable to one share of Common Stock is equal to or greater than SP₀ as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive, for each $1,000 principal amount of Securities upon conversion, the amount of Distributed Property such holder would have received had such holder owned a number of shares of Common Stock equal to the Conversion Rate on the record date fixed for determination for Shareholders entitled to receive such distribution. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such record date had not been fixed. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 4.06(c) by reference to the actual or when issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the average of the Closing Prices of the Common Stock for purposes of calculating SP₀ in the formula in this Section 4.06(c).

With respect to an adjustment pursuant to this Section 4.06(c) where there has been a payment of a dividend or other distribution on the Common Stock consisting of shares of capital stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company (a “Spin-Off,” and any such dividend or distribution of Common Stock, shares of capital stock or equity interests being “Spin-Off Securities”), the Conversion Rate in effect immediately before the Close of Business on the 15^th Trading Day immediately following, and including, the Ex Date for the distribution of the Spin-Off Securities shall be increased based on the following formula:

where

CR0	=	the Conversion Rate in effect immediately prior to the Close of Business on the 15th Trading Day immediately following, and including, the Ex Date for the distribution of the Spin-Off Securities;
CR'	=	the Conversion Rate in effect from and after the Close of Business on the 15th Trading Day immediately following, and including, the Ex Date for the distribution of the Spin-Off Securities;

28

FMV0	=	the average of the Closing Prices of the capital stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Day period commencing on, and including, the fifth Trading Day after the Ex Date for such distribution; and
MP0	=	the average of the Closing Prices of Common Stock over the first 10 consecutive Trading Day period commencing on, and including, the fifth Trading Day after the Ex Date for such distribution.

Such adjustment shall occur at the Close of Business on the 15^th Trading Day from, and including, the Ex Date for the distribution of the Spin-Off Securities; provided, however, that the Company may in lieu of the foregoing adjustment elect to make adequate provision so that each Holder of Securities shall have the right to receive upon conversion thereof the amount of such Spin-Off Securities that such Holder of Securities would have received if such Securities had been converted on the record date with respect to such distribution.

Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for, purchase or convert into shares of the Company’s capital stock (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 shares of 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 4.06(c), (and no adjustment to the Conversion Rate under this Section 4.06(c), will be required) until the occurrence of the earliest Trigger Event, whereupon such rights or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 4.06(c). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this First Supplemental Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of Indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders 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 was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 4.06(c) was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders 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 repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights or warrants had not been issued.

29

For purposes of this Section 4.06(c), Section 4.06(a) and Section 4.06(b), any dividend or distribution to which this Section 4.06(c) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 4.06(a) or 4.06(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of Indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights or warrants to which Section 4.06(a) or 4.06(b) applies (and any Conversion Rate adjustment required by this Section 4.06(c) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants to which Section 4.06(a) or 4.06(b) applies (and any further Conversion Rate adjustment required by Section 4.06(a) or 4.06(b) with respect to such dividend or distribution shall then be made), except (A) the Ex Date of such dividend or distribution shall be substituted for “the Ex Date,” “the Ex Date or effective date,” “the day following the Ex Date for such dividend or distribution or the effective date of such share split or share combination” and “the Ex Date for such issuance” within the meaning of Section 4.06(a) and Section 4.06(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding immediately prior to the Ex Date or effective date” within the meaning of Section 4.06(a).

(d) If a cash dividend or distribution is made to all holders of Common Stock (other than (i) in connection with the Company’s liquidation, dissolution or winding up or (ii) distributions described in Section (e)), the Conversion Rate shall be adjusted based on the following formula:

where

CR0	=	the Conversion Rate in effect at the Close of Business on the Business Day immediately prior to the Ex Date for such dividend or distribution;
CR'	=	the Conversion Rate in effect on and after the Ex Date for such distribution;
SP0	=	the average Closing Price of the Common Stock over the five consecutive Trading Day period ending on the Trading Day immediately preceding the Ex Date for such dividend or distribution; and
C	=	the amount in cash per share the Company dividends or distributes to holders of Common Stock.

Such adjustment shall become effective immediately after the Close of Business on the Ex Date for such dividend or distribution; provided that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than SP₀ as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive, for each $1,000 principal amount upon conversion, the amount of cash such Holder would have received had such Holder owned a number of shares of Common Stock equal

30

to the Conversion Rate on the Ex Date. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

For the avoidance of doubt, for purposes of this Section 4.06(d), in the event of any reclassification of the Common Stock, as a result of which the Securities become convertible into more than one class of Common Stock, if an adjustment to the Conversion Rate is required pursuant to this Section 4.06(d), references in this Section to one share of Common Stock or Closing Price of one share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of Common Stock into which the Securities are then convertible equal to the numbers of shares of such class issued in respect of one share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications.

(e) If the Company or any of its Subsidiaries makes a distribution of cash or other consideration in respect of a tender offer or exchange offer for all or any portion of the Common Stock, in which such cash and the and the value of any such other consideration included in the distribution per share of Common Stock validly tendered or exchanged exceeds the Current Market Price of the Common Stock on the 10^th Trading Day immediately following the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), the Conversion Rate shall be increased based on the following formula:

where

CR0	=	the Conversion Rate in effect immediately before the Close of Business on the expiration date;
CR'	=	the Conversion Rate in effect on and after the effective date of the adjustment;
AC	=	the aggregate value of all cash and any other consideration (as determined in good faith by the Company’s Board of Directors) distributed (or to be distributed) for shares purchased in such tender or exchange offer;
OS0	=	the number of shares of Common Stock outstanding immediately prior to the time such tender or exchange offer expires (including shares validly tendered and not withdrawn in connection with the tender or exchange offer but excluding shares held in treasury);
OS'	=	the number of shares of Common Stock outstanding as of the last time tenders or exchanges could have been made pursuant to such tender or exchange offer (excluding any shares validly tendered and not withdrawn pursuant to the tender or exchange offer or shares held in treasury); and
SP'	=	the Current Market Price.

31

The adjustment to the Conversion Rate under this Section 4.06(e) shall retroactively occur immediately prior to the opening of business on the Ex Date.

If the Company or a Subsidiary is obligated to repurchase shares of Common Stock pursuant to any such tender or exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases or all or any portion of such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had only been made in respect of the purchases that had been effected. Except as set forth in the preceding sentence, if an adjustment to the Conversion Rate pursuant to this Section 4.06(e) with respect 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 or exchange offer under this Section 4.06(e). If an adjustment to the Conversion Rate is required pursuant to this Section 4.06(e) during any settlement period in respect of Securities that have been tendered for conversion, delivery of the related conversion consideration will be delayed to the extent necessary in order to complete the calculations provided for in this Section 4.06(e).

(f) For purposes of this Section 4.06 the term “record date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of shareholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

(g) If application of the formulas provided in Sections 4.06(a), 4.06(b), 4.06(c), 4.06(d) or 4.06(e) would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made except in the case of a share split or combination of the Common Stock.

(h) In any case in which this Section 4.06 shall require that an adjustment be made following a record date, Ex Date, effective date or expiration date, as the case may be, established for purposes of this Section 4.06, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in Section 4.11) issuing to the Holder of any Security converted after such record date, Ex Date, effective date or expiration date the shares of Common Stock and other capital stock of the Company, evidences of indebtedness or other non-Cash assets or rights or warrants issuable upon such conversion over and above Cash payable, or the shares of Common Stock and other capital stock of the Company, evidences of indebtedness or other non-Cash assets or rights or warrants issuable, upon such conversion only on the basis of the Conversion Rate prior to adjustment; and, in lieu of the shares, evidences of indebtedness or other non-Cash assets or rights or warrants the issuance of which, or Cash the payment of which, is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by the Company of the right to receive such shares or Cash, as the case may be. If any distribution in respect of which an adjustment to the Conversion Rate is required to be made as of the record

date, Ex Date, effective date or expiration date therefor is not thereafter made or paid by the Company for any reason, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect if such record date had not been fixed or such Ex Date, effective date or expiration date had not occurred.

(i) If one or more events occur requiring an adjustment be made to the Conversion Rate for a particular period, adjustments to the Conversion Rate shall be determined by the Company’s Board of Directors to reflect the combined impact of such Conversion Rate adjustments, as set out in this Section 4.06, during such period.

Section 4.07. No Adjustment. No adjustment in the Conversion Rate shall be required unless the adjustment would result in a change in the Conversion Rate of at least 1.00%; provided, however, that any adjustment which by reason of this Section 4.07 is not required to be made shall be carried forward and taken into account in subsequent adjustments and in connection with any conversion of Securities; provided, further, however, that adjustments not otherwise made by reason of this Section 4.07 will be made (i) upon conversion of any Securities, (ii) upon a repurchase of the Securities pursuant to Article 3 and (iii) 25 Trading Days prior to the Maturity Date. All calculations under this Article 4 shall be made to the nearest one-ten thousandth (1/10,000) of a cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be.

No adjustment in the Conversion Rate or the Incremental Share Factor need be made for (i) issuances of Common Stock pursuant to any present or future Company plan for reinvestment of dividends or interest payable on the Company’s securities or the investment of additional optional amounts thereunder in shares of Common Stock, (ii) upon the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries, (iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described under (ii) above and outstanding as of the date the Securities were first issued, (iv) a change in the par value of the Common Stock or (v) accrued and unpaid interest, including Additional Interest, if any.

No adjustment to the Conversion Rate need be made pursuant to Section 4.06 for a transaction if Holders are permitted to participate in the transaction without conversion on a basis and with notice that the Board of Directors of the Company determines in good faith to be fair and appropriate in light of the basis and notice on which holders of Common Stock participate in the transaction. For the avoidance of doubt, if a distribution occurs that would generally result in adjustment of the number of shares deliverable to Holders of the Securities as a portion of conversion consideration to which such Holders are entitled, instead of making that adjustment, the Company may instead deem such Holders to be Holders of record for purposes of that distribution so that such Holders would receive the distribution at the time they receive the conversion consideration.

Whenever a provision of the Indenture requires the calculation of an average of the Closing Price over a span of multiple days, the Company will make appropriate adjustments to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring

33

an adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex Date of the event occurs, at any time during the period from which the average is to be calculated.

Section 4.08. Shareholder Rights Agreements. Upon conversion of the Securities, the Holders shall receive, in addition to any shares of Common Stock issuable upon such conversion, any associated rights issued under any future shareholder rights agreement the Company adopts that provides that each share of Common Stock issued upon conversion of the Securities at any time prior to the distribution of separate certificates representing such rights will be entitled to receive such rights unless, prior to conversion, the rights have separated from the Common Stock, expired, terminated or been redeemed or exchanged in accordance with such rights plan, and no adjustment shall be made to the Conversion Rate pursuant to Section 4.06. If the rights have separated from the Common Stock, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all holders of Common Stock, shares of capital stock, evidences of Indebtedness or assets as described in Section 4.06(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 4.09. Effect of Reclassification, Consolidation, Merger or Sale on Conversion Privilege. If (1) there shall occur (a) any reclassification of the 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 a change as a result of a subdivision or combination of the Common Stock); (b) a statutory share exchange, consolidation, merger or combination involving the Company; or (c) a sale or conveyance as an entirety or substantially as an entirety of the property and assets of the Company, directly or indirectly, to another Person; and (2) pursuant to such reclassification, statutory share exchange, consolidation, merger, combination, sale or conveyance, holders of outstanding shares of Common Stock would be entitled to receive stock, other securities, other property or assets (including Cash or any combination thereof) for such shares of Common Stock (any such event a “Merger Event”), then the Company, or such successor or surviving, purchasing or transferee Person, as the case may be, shall, as a condition precedent to such Merger Event, execute and deliver to the Trustee a supplemental indenture signed by the principal executive officer, principal financial officer or principal accounting officer of the Company and at least one other Officer of the Company and providing that, at the effective time of the Merger Event, the right to convert a Security will be changed into a right to convert it into the kind and amount of shares of stock, other securities or other property or assets (including Cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”) upon such transaction (assuming for such purposes that such conversion were settled entirely in Common Stock and without giving effect to any adjustment to the Conversion Rate with respect to a Make-Whole Fundamental Change) immediately prior to such Merger Event, except that such Holders will not be entitled to an increase in the Conversion Rate if such Holder does not convert its Securities “in connection with” the relevant Fundamental Change. If the Merger Event causes the Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), the Reference Property into which the Securities will be convertible will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election. None of the foregoing provisions shall affect the right of a holder of Securities to

34

convert its Securities in accordance with the provisions of this Article 4 prior to the effective date of such Merger Event. Such supplemental indenture shall provide for adjustments of the Conversion Rate which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in this Article 4. The provisions of this Section 4.09 shall similarly apply to successive Merger Events.

Section 4.10. Other Adjustments. Subject to applicable stock exchange rules and listing standards, the Company shall be entitled to increase the Conversion Rate by any amount for a period of at least 20 days if the Board of Directors determines that such increase would be in the best interests in the Company, provided the Company has given to Holders at least 15 days’ prior notice, in accordance with Section 1.04, of any such increase in the Conversion Rate. Subject to applicable stock exchange rules and listing standards, the Company shall be entitled to increase the Conversion Rate, in addition to the events requiring an increase in the Conversion Rate pursuant to Section 4.06, as it in its discretion shall determine to be advisable in order to avoid or diminish any tax to shareholders in connection with any stock dividends, subdivisions of shares, distributions of rights to purchase stock or securities or distributions of securities convertible into or exchangeable for stock hereafter made by the Company to its shareholders.

Section 4.11. Notice of Adjustment. Whenever the Conversion Rate or conversion privilege is adjusted, the Company shall promptly mail to Holders a notice of the adjustment in accordance with Section 1.04, and file with the Trustee an Officers’ Certificate briefly stating the Conversion Rate, the facts requiring the adjustment and the manner of computing it. Unless and until the Trustee shall receive an Officers’ Certificate setting forth an adjustment of the Conversion Rate, the Trustee may assume without inquiry that the Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge remains in effect.

Section 4.12. Trustee’s / Conversion Agent’s Disclaimer. Neither the Trustee nor the Conversion Agent shall have any duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such adjustment set forth in, and shall be protected in relying upon, an Officers’ Certificate, including the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.11. Neither the Trustee nor the Conversion Agent make any representation as to the validity or value of any securities or assets issued upon conversion of Securities, and shall not be responsible for the Company’s failure to comply with any provisions of this Article 4 Neither Trustee nor Conversion Agent shall have any obligation to monitor the stock price.

The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 4.09, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers’ Certificate and Opinion of Counsel with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.09.

Section 4.13. Settlement Upon Conversion. If Securities are surrendered for conversion after the Close of Business on a Record Date for the payment of interest but prior to 9:00 a.m., New York City time on the corresponding Interest Payment Date, a Holder of such Securities at the Close of Business, on such Record Date will receive the interest payable on such Securities

35

on the corresponding Interest Payment Date notwithstanding the conversion of those Securities prior to that Interest Payment Date, assuming such Holder was the holder of record of such Securities at the Close of Business on such Record Date; provided, however, that each Holder agrees, by accepting a Security, that if the Holder surrenders any Securities for conversion during such period, such Holder must pay the Company at the time such Holder surrenders its Securities for conversion interest in accordance with the next sentence. Securities surrendered for conversion during the period from the Close of Business on any Record Date to 9:00 a.m., New York City time, on the immediately following Interest Payment Date, must be accompanied by funds equal to the amount of interest (including Additional Interest, if any) payable on such Interest Payment Date on the Securities so converted; provided that no such payment need be made (a) if the Company has specified a Fundamental Change Purchase Date in respect of the Securities that is after the Close of Business on a Record Date and on or prior to 9:00 a.m., New York City time on the corresponding Interest Payment Date; (b) in respect of any conversion which occurs after the Close of Business on the Record Date for the interest payment due on the Maturity Date and on or prior to the Maturity Date or (c) to the extent of any overdue interest, if any such amount exists at the time of conversion with respect to such Security.

ARTICLE 5

(b) The Company shall notify the Trustee in writing of any changes to its fiscal year.

Section 5.03. Stay, Extension and Usury Laws. The Company covenants, to the extent it may lawfully do so, that it shall not at any time insist upon, plead or in any manner whatsoever claim or take the benefit or advantage of any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal amount or Fundamental Change Purchase Price in respect of Securities, or any interest (including any Additional Interest) on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of the Indenture, and the Company, to the extent it may lawfully do so, hereby expressly waives all benefit or advantage of any such law and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee or any Agent, but shall suffer and permit the execution of every such power as though no such law had been enacted.

The notice given pursuant to this Section 7.01 must be in writing, specify the Default and demand that it be remedied and state that the notice is a “Notice of Default.” When any Default under this Section 7.01 is cured in accordance herewith, it shall cease to be a Default;

The term “Bankruptcy Law” means Title 11 of the United States Code (or any successor thereto) or any similar federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law.

39

The Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to a Responsible Officer at the Corporate Trust Office of the Trustee by the Company (including, without limitation, pursuant to Section 10.7 of the Base Indenture), the Paying Agent, any Holder or any agent of any Holder, which notice references the Securities and this First Supplemental Indenture.

Section 7.02. Acceleration. If an Event of Default (other than an Event of Default with respect to the Company specified in clauses (h) or (i) of Section 7.01) occurs and is continuing, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare all unpaid principal of, plus interest (including Additional Interest, if any) accrued and unpaid through the date of such declaration on, all the Securities then outstanding to be due and payable upon any such declaration, and the same shall thereupon become and be immediately due and payable.

If an Event of Default with respect to the Company specified in clause (g) or (i) of Section 7.01 occurs, all unpaid principal of, plus interest (including Additional Interest, if any) accrued and unpaid through the date of such default on, all the Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

The Holders of a majority in aggregate principal amount of the Securities then outstanding or the Holders originally causing the acceleration by notice to the Trustee may rescind an acceleration of Securities and its consequences before a judgment or decree for the payment of money has been obtained by the Trustee if (a) the rescission would not conflict with any existing order or decree, (b) all existing Events of Default, other than the nonpayment of the principal of, plus accrued and unpaid interest (including Additional Interest, if any) on, the Securities that has become due solely by such declaration of acceleration, have been cured or waived and (c) all payments due to the Trustee and any predecessor Trustee under Section 6.7 of the Base Indenture have been made. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

Section 7.03. Other Remedies. Notwithstanding anything to the contrary in this indenture, to the extent elected by the Company, the sole remedy for an Event of Default relating to the Company’s failure to comply with the covenant set forth in Section 5.02 hereof, for the failure to file any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act or for any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act (any such obligation, the “Reporting Obligations”), shall (i) for the first 120 days after the occurrence of such an Event of Default consist exclusively of the right to receive additional interest on the Securities in an amount equal to 0.25% of the principal amount of the Securities and (ii) for the next 90 days after the expiration of such 120 day period consist exclusively of the right to receive additional interest on the Securities in an amount equal to an additional 0.25% of the principal amount of Securities (such amounts under each of clause (i) and (ii), “Additional Interest”). If the

40

Company so elects, such Additional Interest will be payable on all outstanding Securities on or before the date on which the Event of Default first occurs in the case of the first extension period and on or before the 120th day after such Event of Default first occurs in the case of the second extension period. On the 121st day after such Event of Default (if such Event of Default has not been cured or waived prior to such 121st day and if the Additional Interest relating to the second extension period is not paid on or before such date) or on the 211th day after such Event of Default (if the Additional Interest relating to the second extension period was paid and the Event of Default relating to failure to comply with Reporting Obligations is not cured or waived prior to such 211th day), the Securities will be subject to acceleration as provided above. The provisions set forth in this paragraph will not affect the rights of Holders of Securities in the event of the occurrence of any other Event of Default. In the event the Company does not elect to pay the Additional Interest in accordance with this paragraph, the Securities will be subject to acceleration as provided above. In order to elect to pay the Additional Interest as the sole remedy in respect of the first 210 days after the occurrence of an Event of Default relating to failure to comply with the Reporting Obligations, the Company must (i) notify the Trustee and the Paying Agent in writing of such election and (ii) pay all such Additional Interest as described above, in the case of the first extension period, on or before the close of business on the date on which such Event of Default first occurs and, in the case of the second extension period, on or before the 120^th day after such Event of Default first occurs. Upon the Company’s failure to timely give such notice or pay the Additional Interest, the Securities will be subject to acceleration as provided above.

Section 7.04. Waiver of Defaults and Events of Default. Subject to Section 7.07 and 9.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may waive an existing or future Default or Event of Default and its consequences, except a Default or Event of Default in the payment of the principal of, or any interest (including Additional Interest, if any) on any Security, or the payment of any applicable Fundamental Change Purchase Price, or a failure by the Company to deliver shares of Common Stock (and Cash in lieu of any fractional shares) upon conversion in accordance with Article 4 or any Default or Event of Default in respect of any provision of this First Supplemental Indenture or the Securities that, under Section 9.02, cannot be modified or amended without the consent of the Holders of each outstanding Security. When a Default or Event of 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 7.04 shall be in lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) is hereby expressly excluded from this First Supplemental Indenture, as permitted by the Trust Indenture Act.

Section 7.05. Control by Majority. The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it under this First Supplemental Indenture. However, the Trustee may refuse to follow any direction that conflicts with law or this First Supplemental Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is offered security or indemnity reasonably satisfactory to it; provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. This Section 7.05 shall be in lieu of Section 316(a)(1)(A) of the Trust Indenture Act and such Section 316(a)(1)(A) is hereby expressly excluded from this First Supplemental Indenture, as permitted by the Trust Indenture Act.

41

Section 7.06. Limitations on Suits. Subject to Section 7.07, a Holder of a Security may not pursue any remedy with respect to this First Supplemental Indenture or the Securities unless:

(a) the Holder gives to the Trustee written notice of a continuing Event of Default;

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

(c) such Holder or Holders offer to the Trustee security or indemnity reasonably 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 the notice, request and the offer of security or indemnity; and

(e) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Securities then outstanding.

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

Section 7.07. Rights of Holders to Receive Payment and to Convert. Notwithstanding any other provision of this First Supplemental Indenture, the right of any Holder of a Security to receive payment in Cash of the principal amount, Fundamental Change Purchase Price or interest (including Additional Interest, if any) on any Security, on or after the respective due dates expressed in the Security and this First Supplemental Indenture, receive shares of Common Stock (and Cash in lieu of fractional shares) upon conversion in accordance with Article 4 and 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 without the consent of the Holder.

Section 7.08. Collection Suit by Trustee. If an Event of Default in the payment of principal or interest (including Additional Interest, if any) or Additional Interest specified in clause (a) or (a) of Section 7.01 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 6.7 of the Base Indenture.

Section 7.09. Priorities. Any money or property collected by the Trustee pursuant to this Article 7, and after an Event of Default, any money or other property distributable in respect of the Company’s obligations under this First Supplemental Indenture shall be paid out in the following order:

First, to the Trustee (including any predecessor Trustee) for amounts due under Section 6.7 of the Base Indenture;

42

Second, to Holders for amounts due and unpaid on the Securities for the principal amount, interest (including Additional Interest, if any), the Fundamental Change Purchase Price, amounts due upon conversion (including amounts resulting from a Make-Whole Fundamental Change), 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 7.09. At least 15 days before 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 7.10. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this First Supplemental 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 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 7.10 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 7.07, or a suit by Holders of more than 10% in aggregate principal amount of the Securities then outstanding.

Section 7.11. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 7 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

ARTICLE 8

SUPPLEMENTAL PROVISIONS RELATING TO TRUSTEE

Section 8.01. Reports by Trustee. (a) Within sixty (60) days after May 15 of each year commencing with the year 2008, the Trustee shall transmit to Holders such reports dated as of May 15 of the year in which such report is made concerning the Trustee and its actions under the Indenture as may be required pursuant to the Trust Indenture Act, including, without limitation, Section 313(a) thereof, at the times and in the manner provided pursuant thereto. In the event that, on any such reporting date, no events have occurred under the applicable sections of the Trust Indenture Act within the 12 months preceding such reporting date, the Trustee shall be under no duty or obligation to provide such reports. The Trustee shall also comply with Trust Indenture Act Section 313(b)(2). The Trustee shall transmit by mail all reports as required by Trust Indenture Act Section 313(c).

AMENDMENTS, SUPPLEMENTS AND WAIVERS

Section 9.01. Without Consent of Holders. The Company and the Trustee may amend or supplement the Indenture or the Securities without prior notice to, or consent of, any Holder:

(a) to evidence the succession of another person to the Company, in accordance with Section 6.01(a), and the assumption by any such other successor of the Company’s covenants contained in the Indenture and the Securities;

(b) to add to the covenants of the Company for the benefit of the Holders or to surrender any right or power conferred upon the Company;

(c) to add a guarantor;

(d) to evidence and provide for the acceptance of appointment under the Indenture by a successor Trustee with respect to the Securities and to add to or change any of the provisions of the Indenture as shall be necessary to provide for or facilitate the administration of the trusts thereunder by more than one Trustee;

(e) to cure any ambiguity or to correct or supplement any provision in the Indenture which may be defective or inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under the Indenture which shall not adversely affect the interests of the Holders in any material respect;

(f) to add any additional Events of Default with respect to any of the Securities;

(g) to supplement any of the provisions of the Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of any of the Securities hereunder; provided, however, that any such action shall not adversely affect the interests of any Holder in any material respect, as evidenced by an opinion of counsel;

(h) to make provisions with respect to conversion or exchange rights of Holders; provided, however, that any such action shall not adversely affect the interests of any Holder in any material respect; or

44

(i) to maintain the qualification of the Indenture under the Trust Indenture Act.

Section 9.02. With Consent of Holders. The Company and the Trustee may amend or supplement the Securities or the Indenture with the consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding. Subject to Section 7.04 and Section 7.07, the Holders of at least a majority in aggregate principal amount of the Securities then outstanding may, without prior notice to the Holders of Securities, waive compliance in any instance by the Company with any provision of the Securities or the Indenture or waive any past default under the Indenture and its consequences, except a default in the payment of any amount due, or in the obligation to deliver Common Stock, with respect to any Security or in respect of any provision which under the Indenture cannot be modified or amended without the consent of the Holder of each Security affected. However, notwithstanding the foregoing but subject to Section 9.04, without the consent of the Holders of each Security then outstanding, an amendment, supplement or waiver may not:

(a) change the stated maturity of the principal of or the payment date of any installment of interest (including Additional Interest, if any) on or with respect to the Securities;

(b) reduce the principal amount of, the Fundamental Change Purchase Price of, or the Conversion Rate (except as provided in the Indenture) or rate of interest or Additional Interest on, any Security;

(c) reduce the amount of principal payable upon acceleration of the maturity of any Security;

(d) change the currency in which payment of principal of, the Fundamental Change Purchase Price of, or interest with respect to, the Securities is payable;

(e) impair the right to institute suit for the enforcement of any payment on, or with respect to, any Security;

(f) modify the provisions with respect to the repurchase rights of Holders as provided in Article 3 in a manner adverse to Holders;

(g) adversely affect the right of Holders to convert Securities in any material respect, other than as provided in the Indenture;

(h) cause the Securities to be subordinated to other Indebtedness;

(i) reduce the percentage in principal amount of the outstanding Securities, the consent of whose Holders is required to take specific actions including, but not limited to, the waiver of past defaults or the modification or amendment of the Indenture; or

(j) alter the manner of calculation or rate of accrual of interest or Additional Interest or Fundamental Change Purchase Price or the Conversion Rate (except as provided in the Indenture) on any Security or extend the time for payment of any such amount.

45

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under Section 9.01 or this Section 9.02 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

Section 9.03. Compliance with Trust Indenture Act. Every amendment to or supplement of the Indenture or the Securities shall comply with the Trust Indenture Act as in effect at the date of such amendment or supplement.

Section 9.04. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective.

After any amendment, supplement or waiver becomes effective, it shall bind every applicable Holder.

Section 9.05. Notation on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

Section 9.06. Trustee to Sign Amendments, etc. The Trustee shall sign any amendment or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee in any material respect. If it does adversely affect the rights, duties, liabilities or immunities of the Trustee in any material respect, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing to sign such amendment or supplemental indenture, the Trustee shall be provided with and, subject to Section 6.1 of the Base Indenture, shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment or supplemental indenture is authorized or permitted by the Indenture and that all conditions precedent to the effectiveness of such amendment or supplement have been satisfied or duly waived.

Section 9.07. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, the Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of the Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

46

ARTICLE 10

SATISFACTION AND DISCHARGE

Section 10.01. Satisfaction and Discharge of the Indenture. This Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this First Supplemental Indenture, when

Notwithstanding anything herein to the contrary, Section 3.6, Section 3.7, Section 6.7 and Section 10.2 of the Base Indenture and Section 2.04, Section 2.06, Section 2.08, Section 5.01, Section 5.03, and Article 4 and Article 10 of this First Supplemental Indenture, shall survive any discharge of this First Supplemental Indenture until such time as there are no Securities outstanding.

This Security is one of a duly authorized issue of 2.75% Convertible Senior Notes due February 15, 2013 (the “Securities”) of the Company issued under a first supplemental indenture, dated as of February 12, 2008 (the “Supplemental Indenture”), between the Company and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”), supplemental to the indenture, dated as of February 12, 2008 (the “Base Indenture,” and together with the Supplemental Indenture, the “Indenture”). The terms of the Security include those stated in the Indenture, those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”), and those set forth in this Security. This Security is subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable law, if any provision of this Security conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. Capitalized terms used but not defined herein have the meanings assigned to them in the Indenture unless otherwise indicated.

Interest on the Securities will accrue on the principal amount from, and including, the most recent date to which interest has been paid or provided for or, if no interest has been paid, from, and including, February 12, 2008, in each case to, but excluding, the next Interest Payment Date or Maturity Date, as the case may be. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment.

Payment of the principal of, and interest (including any Additional Interest) on, the Securities shall be made at the office of the Paying Agent in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. The Holder must surrender this Security to a Paying Agent to collect payment of principal. Payment of interest on Registered Securities shall be made by check mailed to the address of the Person entitled thereto as such address appears in the Register; provided, however, that Holders with Securities in an aggregate principal amount in excess of $5.0 million shall be paid, at their written election, by wire transfer of immediately available funds. Notwithstanding the foregoing, so long as the Securities are registered in the name of a Depositary or its nominee, all payments with respect to the Securities shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee.

Ladies and Gentlemen,

We have acted as securities counsel to RadiSys Corporation, an Oregon corporation (the “Company”), in connection with the registration statement on Form S-3 (Registration No. 333-146977), including the prospectus dated November 7, 2007, as supplemented by the prospectus supplement dated February 6, 2008, filed by the Company under the Securities Act of 1933, as amended (the “Securities Act”) with the Securities and Exchange Commission (the “SEC”) (the registration statement, as amended to date, is hereafter referred to as the “Registration Statement”). The Registration Statement relates to the public offering of $55,000,000 aggregate principal amount of 2.75% Convertible Senior Notes due 2013 of the Company (the “Notes”).

We have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Second Restated Articles of Incorporation and the Restated Bylaws of the Company, each as amended to the date hereof (the “Charter Documents”), (ii) resolutions adopted by the Board of Directors of the Company and the Financing Committee of the Board of Directors authorizing the issuance of the Notes and related matters (the “Resolutions”), (iii) the Registration Statement and all exhibits thereto, (iv) the form of the Indenture, dated February 12, 2008, between the Company and The Bank of New York Trust Company, N.A., as Trustee (the “Trustee”), as supplemented by the First Supplemental Indenture between the Company and the Trustee, dated as of the date thereof, providing for the issuance of the Notes (the “Indenture”), and (v) such other certificates, statutes and other instruments and documents as we considered appropriate for purposes of the opinions hereafter expressed.

As to any facts material to our opinion, we have made no independent investigation of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Company.

In rendering the opinions set forth below, we have assumed that (i) all information contained in all documents reviewed by us is true and correct, (ii) all signatures on all documents examined by us are genuine, (iii) all documents submitted to us as originals are authentic and all documents submitted to us as copies conform to the originals of those documents, (iv) each natural person signing any document reviewed by us had the legal capacity to do so and (v) any document under which, if applicable, the Notes may be issued have been or will have been duly authorized, executed and delivered by persons with authority to sign in such capacity.

Based on the foregoing, we are of the opinion that, when the Notes shall have been executed and authenticated as specified in the Indenture and offered and sold as described in the Registration Statement, the Notes will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforcement thereof may be limited by or subject to bankruptcy, insolvency, fraudulent transfer or conveyance, reorganization, moratorium or other similar laws relating to or affecting creditors' rights generally, and general equitable or public policy principles.

The foregoing opinion is limited in all respects to the corporate laws of the State of New York and the federal laws of United States of America, in each case, that, in our experience, are normally applicable to transactions of the type contemplated by the Registration Statement and, to the extent that judicial or regulatory orders or decrees or consents, approvals, licenses, authorizations, validations, filings, recordings or registrations with governmental authorities are relevant, to those required under such laws, and we do not express any opinions as to the laws of any other jurisdiction. With respect to all matters of Oregon law, we note that you are being provided with the opinion, dated on or about the date hereof, of Stoel Rives LLP, Oregon counsel to the Company. For purposes of our opinion, we have assumed that the Company has been duly incorporated and is a validly existing corporation under the laws of Oregon and that, where applicable, the issuance or delivery by the Company of any shares of its common stock upon exercise or otherwise pursuant to the terms of the Notes will be duly authorized, executed, authenticated, issued and delivered by the Company in accordance with Oregon law and pursuant to the authority granted in the Resolutions and that the authority granted in the Resolutions will remain in effect at all relevant times. We are expressing no opinion as to any obligations that parties other than the Company may have under or in respect of the Notes or as to the effect that their performance of such obligations may have upon any of the matters referred to above.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of our name under the caption "Legal Matters" in the prospectus supplement forming a part of the Registration Statement. In giving this consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act and the rules and regulations of the SEC issued thereunder.

Very truly yours,
