Section 2.04 Authentication and Delivery of Securities. At any time and from time to time after the execution and delivery of the Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a written order of the Company, signed in the name of the Company by any two of the following officers: the chairman of the Board of Directors, the chief executive officer, the chief financial officer, any president, any executive vice president, the treasurer or the secretary of the Company (an “Company Order”). The Trustee, in accordance with such written order, shall authenticate and deliver such Securities.

In authenticating such Securities and accepting the additional responsibilities under the Indenture in relation to such Securities, the Trustee shall be entitled to receive and (subject to Section 5.01) shall be fully protected in relying upon:

(a) a certified copy of any resolution or resolutions of the Board of Directors authorizing the action taken pursuant to the resolution or resolutions delivered under clause 2.04(b) below;

(e) an Opinion of Counsel, prepared in accordance with Section 10.05, to the effect that:

(i) the form or forms and terms of such Securities have been established by or pursuant to a Resolution of the Board of Directors and set forth in an Officers’ Certificate, or by a supplemental indenture as permitted by Section 2.01 and 2.03 in conformity with the provisions of the Indenture; and

(ii) such Securities, when 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 valid and binding obligations of the Company entitled to the benefits of the Indenture, and enforceable against the Company in accordance with their terms, except to the extent

9

that enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws now or hereafter in effect relating to creditor’s rights generally, and general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law).

The Trustee shall have the right to decline to authenticate and deliver any Securities under this section if the Trustee, being advised by counsel, determines that such action may not lawfully be taken by the Company or if the Trustee in good faith by its board of directors or board of trustees, executive committee, or a trust committee of directors or trustees or Responsible Officers shall determine that such action would expose the Trustee to personal liability.

Section 2.05 Execution of Securities. The Securities shall be signed in the name of the Company by any two of the following officers: the chairman of the Board of Directors, the chief executive officer, the chief financial officer, any president, any executive vice president, the treasurer or the secretary of the Company. Such signatures may be the manual, facsimile or other electronic signatures of the present or any future such officers. Typographical and other minor errors or defects in any such signature shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by the Trustee.

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

Section 2.06 Certificate of Authentication. Only such Securities as shall bear thereon a certificate of authentication substantially in the form recited herein, executed by the Trustee by the manual signature of one of its authorized officers, shall be entitled to the benefits of the Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee upon any Security executed by the Company shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of the Indenture.

Section 2.07 Denomination and Date of Securities; Payments of Interest. The Securities shall be issuable as registered securities without coupons and in denominations as shall be specified as contemplated by Section 2.03. In the absence of any such specification with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any multiple thereof. The Securities shall be numbered, lettered, or otherwise distinguished in such manner or in accordance with such plan as the officers of the Company executing the same may determine with the approval of the Trustee as evidenced by the execution and authentication thereof.

Unless otherwise specified pursuant to Section 2.03 of the Indenture, the principal of and the interest on the Securities of any series, shall be payable in the coin or currency of the United States of America that at the time is legal tender for public and private debt, at the office or agency of the Company maintained for that purpose.

10

Each Security shall be dated the date of its authentication, shall bear interest, if any, from the date and shall be payable on the dates, in each case, established as contemplated by Section 2.03.

The person in whose name any Security of any series is registered at the close of business on any record date applicable to a particular series with respect to any interest payment date for such series shall be entitled to receive the interest, if any, payable on such interest payment date notwithstanding any transfer or exchange of such Security subsequent to the record date and prior to such interest payment date, except if and to the extent the Company shall default in the payment of the interest due on such interest payment date for such series, in which case such defaulted interest shall be paid to the persons in whose names Outstanding Securities for such series are registered at the close of business on a subsequent record date (which shall be not less than five Business Days prior to the date of payment of such defaulted interest) established by notice given by mail by or on behalf of the Company to the Holders not less than 15 days preceding such subsequent record date. The term “record date” as used with respect to any interest payment date (except a date for payment of defaulted interest) shall mean the date specified as such in the terms of the Securities of any particular series, or, if no such date is so specified, if such interest payment date is the first day of a calendar month, the fifteenth day of the next preceding calendar month or, if such interest payment date is the fifteenth day of a calendar month, the first day of such calendar month, whether or not such record date is a Business Day.

Section 2.08 Registration, Transfer and Exchange. The Company may appoint one or more Registrars. The Company initially appoints the Trustee as Registrar. The Company will keep or cause to be kept at each office or agency to be maintained for the purpose as provided in Section 3.02 a register or registers (the “Register”) in which, subject to such reasonable regulations as it may prescribe, it will register, and will register the transfer of, Securities as in this Article provided. The Register shall be in written form in the English language or in any other form capable of being converted into such form within a reasonable time. At all reasonable times the Register shall be open for inspection by the Trustee.

Upon due presentation for registration of transfer of any Security of any series at any such office or agency to be maintained for the purpose as provided in Section 3.02, the Company shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Security or Securities of the same series in authorized denominations for a like aggregate principal amount.

Any Security or Securities of any series may be exchanged for a Security or Securities of the same series in other authorized denominations, in an equal aggregate principal amount. Securities of any series to be exchanged shall be surrendered at any office or agency to be maintained by the Company for the purpose as provided in Section 3.02, and the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor the Security or Securities of the same series which the Holder making the exchange shall be entitled to receive, bearing numbers not contemporaneously Outstanding.

11

All Securities presented for registration of transfer, exchange, redemption or payment shall (if so required by the Company or the Trustee) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Trustee duly executed by, the holder or his attorney duly authorized in writing, together with signature guarantees for such holder or attorney.

The Company or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any exchange or registration of transfer of Securities. No service charge shall be made for any such transaction.

Neither the Company nor the Trustee shall be required to exchange or register a transfer of (a) any Securities of any series for a period of 15 days preceding the first mailing of notice of redemption of Securities of such series to be redeemed, or (b) any Securities selected, called or being called for redemption except, in the case of any Security where public notice has been given that such Security is to be redeemed in part, the portion thereof not so to be redeemed.

In addition to the transfer requirements provided in this Section 2.08, any Security or Securities will be subject to such further transfer restrictions as may be contained in an Officers’ Certificate or indenture supplemental hereto applicable to such series of Securities.

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 the Indenture, as the Securities surrendered upon such transfer or exchange.

Section 2.09 Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In case any temporary or definitive Security shall become mutilated, defaced or be destroyed, lost or stolen, the Company in its discretion may execute, and upon the receipt of an Company Order, the Trustee shall authenticate and deliver, a new Security of the same series, bearing a number not contemporaneously Outstanding, in exchange and substitution for the mutilated or defaced Security, or in lieu of and substitution for the Security so destroyed, lost or stolen. In every case the applicant for a substitute Security shall furnish to the Company and to the Trustee and any agent of the Company or the Trustee such security or indemnity as may be required by them to indemnify and defend and to save each of them harmless and, in every case of destruction, loss or theft, evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof.

Upon the issuance of any substitute Security, the Company or the Trustee 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. In case any Security which has matured or is about to mature or has been called for redemption in full shall become mutilated or defaced or be destroyed, lost or stolen, the Company may instead of issuing a substitute Security, pay or authorize the payment of the same (without

12

surrender thereof except in the case of a mutilated or defaced Security), if the applicant for such payment shall furnish to the Company and to the Trustee and any agent of the Company or the Trustee such security or indemnity as any of them may require to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and the Trustee and any agent of the Company or the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof. In case the mutilated, deleted, destroyed, or lost or stolen Security has become or is about to become due and payable, the Company in its discretion may pay the Security instead of issuing a substitute Security.

Every substitute Security of any series issued pursuant to the provisions of this section by virtue of the fact that any such Security is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone and shall be entitled to all the benefits of (but shall be subject to all the limitations of rights set forth in) the Indenture equally and proportionately with any and all other Securities of such series duly authenticated and delivered hereunder. All Securities shall be held and owned upon the express condition that, to the extent permitted by law, the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, defaced or destroyed, lost or stolen Securities and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

Section 2.10 Cancellation of Securities; Destruction Thereof. All Securities surrendered for payment, redemption, registration of transfer or exchange, or for credit against any payment in respect of a sinking or analogous fund, if surrendered to the Company or any agent of the Company or the Trustee, shall be delivered to the Trustee for cancellation or, if surrendered to the Trustee, shall be cancelled by it; and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of the Indenture. On written request of the Company at the time of such surrender, the Trustee shall deliver to the Company the Securities cancelled by the Trustee. In the absence of such request, the Trustee shall destroy cancelled Securities held by it and, upon request, deliver a certificate of destruction to the Company. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation.

Section 2.11 Temporary Securities. Pending the preparation of definitive Securities for any series, the Company may execute and the Trustee shall, upon receipt of an Company Order, authenticate and deliver temporary Securities for such series (printed, lithographed, typewritten or otherwise reproduced, in each case in form satisfactory to the Trustee). Temporary Securities of any series shall be issuable as registered Securities without coupons, of any authorized denomination, and substantially in the form of the definitive Securities of such series but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company with the concurrence of the Trustee. Temporary Securities may contain such reference to any provisions of the Indenture as may be appropriate. Every temporary Security shall be executed by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities. Without

13

unreasonable delay the Company shall execute and shall furnish definitive Securities of such series and thereupon temporary Securities of such series may be surrendered in exchange therefor without charge at each office or agency to be maintained by the Company for that purpose pursuant to Section 3.02, and the Trustee shall, upon receipt of an Company Order, authenticate and deliver in exchange for such temporary Securities of such series a like aggregate principal amount of definitive Securities of the same series of authorized denominations. Until so exchanged, the temporary Securities of any series shall be entitled to the same benefits under the Indenture as definitive Securities of such series.

Section 2.12 Authenticating Agent. So long as any of the Securities of any series remain Outstanding there may be an Authenticating Agent for any or all such series of Securities which the Trustee shall have the right to appoint. Said Authenticating Agent shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon exchange, transfer or partial redemption thereof, and Securities so authenticated shall be entitled to the benefits of the Indenture and shall be valid and binding for all purposes as if authenticated by the Trustee hereunder. All references in the Indenture to the authentication of Securities by the Trustee shall be deemed to include authentication by an Authenticating Agent for such series. Each Authenticating Agent shall be acceptable to the Company and shall be a corporation that has a combined capital and surplus, as most recently reported or determined by it, sufficient under the laws of any jurisdiction under which it is organized or in which it is doing business to conduct a trust business, and that is otherwise authorized under such laws to conduct such business and is subject to supervision or examination by Federal or State authorities. If at any time any Authenticating Agent shall cease to be eligible in accordance with these provisions, it shall resign immediately. Any Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time (and upon written request by the Company shall) terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company. Upon resignation, termination or cessation of eligibility of any Authenticating Agent, the Trustee may appoint an eligible successor Authenticating Agent acceptable to the Company. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder as if originally named as an Authenticating Agent pursuant hereto.

Section 2.13 Global Securities. If the Company shall establish pursuant to Section 2.01 that the Securities of a particular series are to be issued as a Global Security, then the Company shall execute and the Trustee shall, in accordance with Section 2.04, authenticate and deliver, a Global Security that shall (i) represent, and be issued in a denomination or aggregate denominations equal to the aggregate principal amount of all the Securities to be represented by a Global Security, (ii) be registered in the name of the Depositary or its nominee, (iii) be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instruction and (iv) bear a legend substantially to the following effect: “Except as otherwise provided in Section 2.13 of the Indenture, this Security may be transferred, in whole but not in part, only to another nominee of the Depositary or to a successor Depositary or to a nominee of such successor Depositary.”

14

Notwithstanding the provisions of Section 2.08, the Global Security of a series may be transferred, in whole but not in part and in the manner provided in Section 2.08, only to another nominee of the Depositary for such series, or to a successor Depositary for such series selected or approved by the Company or to a nominee of such successor Depositary.

Ownership of beneficial interests in a registered Global Security will be limited to Agent Members that have accounts with the Depositary or persons that may hold interests through Agent Members. Upon the issuance of a registered Global Security, the Depositary will credit, on its book-entry registration and transfer system, the Agent Members accounts with the respective principal or face amounts of the Securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the Securities will designate the accounts to be credited. Ownership of beneficial interests in a Global Security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the Depositary, with respect to interests of Agent Members, and on the records of Agent Members, with respect to interests of persons holding through Agent Members.

So long as the Depositary, or its nominee, is the registered owner of a registered Global Security, that Depositary or its nominee, as the case may be, will be considered the sole owner or Holder of the Securities represented by the Global Security for all purposes under the Indenture. Except as described in this Section 2.13, Agent Members will not be entitled to have the Securities represented by the Global Security registered in their names, will not receive or be entitled to receive physical delivery of the Securities in definitive form and will not be considered the owners or Holders of the Securities under the Indenture. Accordingly, each Agent Member owning a beneficial interest in a registered Global Security must rely on the procedures of the Depositary for that registered Global Security and, if that person is not an Agent Member, on the procedures of the Agent Member through which the person owns its interest, to exercise any rights of a Holder under the Indenture. Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Security through an Agent Member) to take any action which a Holder is entitled to take under the Indenture or the Securities, and nothing herein will impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

Principal, premium, if any, and interest payments on Securities represented by a Global Security registered in the name of the Depositary or its nominee will be made to the Depositary or its nominee, as the case may be, as the registered owner of the registered Global Security. None of the Company, the Trustee or any other agent of the Company, or any agent of the Trustee will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered Global Security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

If at any time the Depositary for a series of the Securities notifies the Company that it is unwilling or unable to continue as Depositary for such series or if at any time the Depositary for such series shall no longer be registered or in good standing under the Exchange Act, or other

15

applicable statute or regulation, and a successor Depositary for such series is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such condition, as the case may be, this Section 2.13 shall no longer be applicable to the Securities of such series and the Company will execute, and subject to Section 2.08, the Trustee will authenticate and deliver the Securities of such series in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Security of such series in exchange for such Global Security. In addition, the Company may at any time determine that the Securities of any series shall no longer be represented by a Global Security and that the provisions of this Section 2.13 shall no longer apply to the Securities of such series. In such event the Company will execute and subject to Section 2.08, the Trustee, upon receipt of an Officers’ Certificate evidencing such determination by the Company, will authenticate and deliver the Securities of such series in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Security of such series in exchange for such Global Security. Upon the exchange of the Global Security for such Securities in definitive registered form without coupons, in authorized denominations, the Global Security shall be cancelled by the Trustee. Such Securities in definitive registered form issued in exchange for the Global Security pursuant to this Section 2.13 shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing. The Company and the Trustee shall be entitled to conclusively rely on such instructions from the Depositary. The Trustee shall deliver such Securities to the Depositary for delivery to the Persons in whose names such Securities are so registered.

Section 2.14 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 in writing of any change in the “CUSIP” numbers.

ARTICLE 3

COVENANTS OF THE COMPANY

Section 3.01 Payment of Principal and Interest. (a) The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay or cause to be paid the principal of, and interest on, each of the Securities of such series at the place or places, at the respective times and in the manner provided in such Securities. Unless otherwise provided in the Securities of any series, not later than 11:00 A.M. (New York City time) on the due date of any principal of or interest on any Securities, the Company will deposit with the Trustee (or paying agent) money in immediately available funds sufficient to pay such amounts, provided that if the Company or any affiliate of the Company is acting as paying agent, it will, on or before each due date, segregate and hold in a separate trust fund for the benefit of the Holders a sum of money sufficient to pay such amounts until paid to such Holders or otherwise disposed of as provided in the Indenture. In each case the Company will promptly notify the Trustee of its compliance with this paragraph.

16

(b) An installment of principal or interest will be considered paid on the date due if the Trustee (or paying agent, other than the Company or any affiliate of the Company) holds at 11:00 a.m. New York City time on that date money designated for and sufficient to pay the installment. If the Company or any affiliate of the Company acts as paying agent, an installment of principal or interest will be considered paid on the due date only if paid to the Holders.

(c) Payments in respect of the Securities represented by the Global Security are to be made by wire transfer of immediately available funds to the accounts specified by the Holder of the Global Security. With respect to certificated Securities, the Company will make all payments by wire transfer of immediately available funds to the accounts specified by the Holders thereof or, if no such account is specified, by mailing a check to each Holder’s registered address.

Section 3.02 Offices for Payments, etc. So long as any of the Securities remain Outstanding, the Company will maintain in the United States, the following for each series: an office or agency (a) where the Securities may be presented for payment, (b) where the Securities may be presented for registration of transfer and for exchange as in the Indenture provided and (c) where notices and demands to or upon the Company in respect of the Securities or of the Indenture may be given or served. The Company will give to the Trustee written notice of the location of any such office or agency and of any change of location thereof. Unless otherwise specified in accordance with Section 2.03, the Company hereby initially designates the Corporate Trust Office of U.S. Bank National Association at One California Street, Suite 1000, San Francisco, California 94111, Attention: Global Corporate Trust Services (Palo Alto Networks), as the office to be maintained by it for each such purpose. In case the Company shall fail to so designate or maintain any such office or agency or shall fail to give such notice of the location or of any change in the location thereof, presentations and demands may be made and notices may be served at the applicable Corporate Trust Office of the Trustee and the Company hereby appoints the Trustee as its agent to receive all such presentations, notices and demands.

Section 3.03 Paying Agents. Whenever the Company shall appoint a paying agent other than the Trustee with respect to the Securities of any series, it will cause such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section,

(a) that it will hold all sums received by it as such agent for the payment of the principal of or interest on the Securities of such series (whether such sums have been paid to it by the Company or by any other obligor on the Securities of such series) in trust for the benefit of the holders of the Securities of such series or of the Trustee,

17

(b) that it will give the Trustee notice of any failure by the Company (or by any other obligor on the Securities of such series) to make any payment of the principal of or interest on the Securities of such series when the same shall be due and payable,

(c) pay any such sums so held in trust by it to the Trustee upon the Trustee’s written request at any time during the continuance of the failure referred to in clause 3.03(b) above, and

(d) that it will perform all other duties of paying agent as set forth in the Indenture.

The Company shall, on or prior to each due date of the principal of or interest on the Securities of such series, deposit with the paying agent a sum sufficient to pay such principal or interest so becoming due, and (unless such paying agent is the Trustee) the Company shall promptly notify the Trustee of any failure to take such action.

If an Company shall act as its own paying agent with respect to the Securities of any Series, it will, on or before each due date of the principal of or interest on the Securities of such series, set aside, segregate and hold in trust for the benefit of the holders of the Securities of such series a sum sufficient to pay such principal or interest so becoming due. The Company will promptly notify the Trustee of any failure to take such action.

Anything in this section to the contrary notwithstanding, the Company may at any time, for the purpose of obtaining a satisfaction and discharge with respect to one or more or all series of Securities hereunder, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust for any such series by the Company or any paying agent hereunder, as required by this Section, such sums to be held by the Trustee upon the trusts herein contained.

Anything in this section to the contrary notwithstanding, the agreement to hold sums in trust as provided in this section is subject to the provisions of Section 9.05 and 9.06.

Section 3.04 Certificate of the Company. The Company will furnish to the Trustee on or before 120 days after the end of each fiscal year (beginning with the fiscal year ended __________, _____) a brief certificate (which need not comply with Section 10.05) from the principal executive, financial or accounting officer or the Treasurer of the Company as to his or her knowledge of the Company’s compliance with all conditions and covenants under the Indenture (such compliance to be determined without regard to any period of grace or requirement of notice provided under the Indenture), or if there has been a default, specifying the default and its nature and status.

Section 3.05 Reports by the Company. Any information, documents or other reports that the Company shall file with the Commission pursuant to Section 13 or 15(d) (excluding any such information, documents or reports, or portions thereof, subject to confidential treatment and any correspondence with the Commission) of the Exchange Act shall be filed with the Trustee within 15 days after the same is filed with the Commission (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act); provided that any such information, documents or reports filed or furnished with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval (or EDGAR) system shall be deemed to be filed with the Trustee as of the time such information, documents or reports are filed or furnished via EDGAR.

18

Section 3.06 Existence. Except as permitted under Article 8, the Company covenants to do or cause to be done all things necessary to preserve and keep in full force and effect its existence.

ARTICLE 4

REMEDIES OF THE TRUSTEE AND HOLDERS ON EVENT OF DEFAULT

Section 4.01 Event of Default; Acceleration of Maturity; Waiver of Default. An “Event of Default” with respect to Securities of any series means the occurrence of one or more of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(a) default in the payment of any installment of interest upon any of the Securities of such series as and when the same shall become due and payable, and continuance of such default for a period of 30 days or more;

(b) default in the payment of the principal, or premium, if any, on any of the Securities of such series as and when the same shall become due and payable either at maturity, upon redemption, by declaration or otherwise;

(c) default in the payment of any sinking fund installment as and when the same shall become due and payable by the terms of the Securities of such series;

(d) default in the performance, or breach, of any covenant of the Company in respect of the Securities of such series (other than defaults pursuant to paragraphs (a), (b) and (c) above), and continuance of such default or breach for a period of 90 days or more after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of all series affected thereby, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder;

(e) a court having jurisdiction in the premises shall enter a decree or order for relief in respect of the Company in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or for any substantial part of its property or ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period of 60 consecutive days;

(f) the Company shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or for any substantial part of its property, or make any general assignment for the benefit of creditors; or

19

(g) any other Event of Default provided in the Officers’ Certificate, supplemental indenture or Resolution of the Board of Directors under which such series of Securities is issued or in the form of Security for such series.

If an Event of Default described in clauses 4.01(a), 4.01(b), 4.01(c), 4.01(d) or 4.01(g) above occurs and is continuing, then, and in each and every such case, unless the principal of all of the Securities of such series shall have already become due and payable, the Trustee may, and at the direction of the holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding hereunder (each such series voting as a separate class) by notice in writing to the Company (and to the Trustee if given by Holders), shall declare the entire principal (or, if the Securities of such series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such series) of all Outstanding Securities of such series, together with all accrued and unpaid interest and premium, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable.

If an Event of Default described in clauses 4.01(e) or 4.01(f) above occurs and is continuing, then the entire principal amount of the Outstanding Securities will automatically become due immediately and payable without any declaration or other act on the part of the Trustee or any Holder.

Notwithstanding the foregoing, the Holders of a majority in principal amount of the Outstanding Securities of any series (each such series voting as a separate class) by written notice to the Company and to the Trustee may on behalf of the Holders of all Securities of such series waive all past defaults and rescind and annul a declaration of acceleration and its consequences if:

(i) all existing Events of Default, other than the nonpayment of the principal of and interest on the Securities that have become due solely by the declaration of acceleration, have been cured or waived, and

(ii) the rescission would not conflict with any judgment or decree.

For all purposes under the Indenture, if a portion of the principal of any Original Issue Discount Securities shall have been accelerated and declared due and payable pursuant to the provisions hereof, then, from and after such declaration, unless such declaration has been rescinded and annulled, the principal amount of such Original Issue Discount Securities shall be deemed, for all purposes hereunder, to be such portion of the principal thereof as shall be due and payable as a result of such acceleration, and payment of such portion of the principal thereof as shall be due and payable as a result of such acceleration, together with interest, if any, thereon and all other amounts owing thereunder, shall constitute payment in full of such Original Issue Discount Securities.

20

Section 4.02 Collection of Indebtedness by Trustee; Trustee May Prove Debt. The Company covenants that (a) in case default shall be made in the payment of any installment of interest on any of the Securities of any series when such interest shall have become due and payable, and such default shall have continued for a period of 30 days or (b) in case default shall be made in the payment of all or any part of the principal of any of the Securities of any series when the same shall have become due and payable, whether upon maturity of the Securities of such series or upon any redemption or by declaration or otherwise—then upon demand of the Trustee, the Company will pay to the Trustee for the benefit of the Holders of the Securities of such series the whole amount that then shall have become due and payable on all Securities of such series for principal or interest, as the case may be (with interest to the date of such payment upon the overdue principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series); and in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee and each predecessor Trustee, their respective agents, attorneys and counsel, and any expenses and liabilities incurred by the Trustee and each predecessor Trustee except as a result of its negligence or bad faith.

Until such demand is made by the Trustee, the Company may pay the principal of and interest on the Securities of any series to the registered holders, whether or not the principal of and interest on the Securities of such series be overdue.

In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment or final decree against the Company or other obligor upon such Securities and collect in the manner provided by law out of the property of the Company or other obligor upon such Securities, wherever situated, the moneys adjudged or decreed to be payable.

In case there shall be pending proceedings relative to the Company or any other obligor upon the Securities under Bankruptcy Law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or its property or such other obligor, or in case of any other comparable judicial proceedings relative to the Company or other obligor upon the Securities of any series, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of any Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such proceedings or otherwise:

(a) to file and prove a claim or claims for the whole amount of principal and interest (or, if the Securities of any series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such series) owing and unpaid in respect of the

21

Securities of any series, 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 reasonable compensation to the Trustee and each predecessor Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of negligence or bad faith) and of the Holders allowed in any judicial proceedings relative to the Company or other obligor upon the Securities of any series, or to the creditors or property of the Company or such other obligor,

(b) unless prohibited by applicable law and regulations, to vote on behalf of the holders of the Securities of any series in any election of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or person performing similar functions in comparable proceedings, and

(c) to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of the Holders and of the Trustee on their behalf; and any trustee, receiver, or liquidator, custodian or other similar official is hereby authorized by each of the Holders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments directly to the Holders, to pay to the Trustee such amounts as shall be sufficient to cover reasonable compensation to the Trustee, each predecessor Trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee except as a result of negligence or bad faith and all other amounts due to the Trustee or any predecessor Trustee pursuant to Section 5.07.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Holder any plan or reorganization, arrangement, adjustment or composition affecting the Securities of any series or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar person.

All rights of action and of asserting claims under the Indenture, or under any of the Securities, may be enforced by the Trustee without the possession of any of the Securities or the production thereof on any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the reasonable expenses, disbursements and compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys, shall be for the ratable benefit of the holders of the Securities in respect of which such action was taken.

In any proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of the Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Securities in respect to which such action was taken, and it shall not be necessary to make any holders of such Securities parties to any such proceedings.

Section 4.03 Application of Proceeds. Any moneys collected by the Trustee pursuant to this Article in respect of any series shall be applied in the following order at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal or interest, upon presentation of the several Securities in respect of which moneys have been collected and stamping (or otherwise noting) thereon the payment, or issuing Securities of such series in reduced principal amounts in exchange for the presented Securities of like series if only partially paid, or upon surrender thereof if fully paid:

FIRST: To the payment of costs and expenses applicable to such series in respect of which moneys have been collected, including reasonable compensation to the Trustee and each predecessor Trustee and their respective agents and attorneys and of all expenses and liabilities incurred by the Trustee and each predecessor Trustee except as a result of negligence or bad faith, and all other amounts due to the Trustee or any predecessor Trustee pursuant to Section 5.07;

SECOND: In case the principal of the Securities of such series in respect of which moneys have been collected shall not have become and be then due and payable, to the payment of interest on the Securities of such series in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in such Securities, such payments to be made ratably to the persons entitled thereto, without discrimination or preference;

THIRD: In case the principal of the Securities of such series in respect of which moneys have been collected shall have become and shall be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such series for principal and interest, with interest upon the overdue principal, and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities of such series, then to the payment of such principal and interest or yield to maturity, without preference or priority of principal over interest or yield to maturity, or of interest or yield to maturity over principal, or of any installment of interest over any other installment of interest, or of any Security of such series over any other Security of such series, ratably to the aggregate of such principal and accrued and unpaid interest or yield to maturity; and

FOURTH: To the payment of the remainder, if any, to the Company or any other person lawfully entitled thereto.

Section 4.04 Suits for Enforcement. In case an Event of Default has occurred, has not been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by the Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in the Indenture or to enforce any other legal or equitable right vested in the Trustee by the Indenture or by law.

23

Section 4.05 Restoration of Rights on Abandonment of Proceedings. In case the Trustee shall have proceeded to enforce any right under the Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee, then and in every such case the Company and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company, the Trustee and the Holders shall continue as though no such proceedings had been taken.

Section 4.06 Limitations on Suits by Holder. No Holder of any Security of any series shall have any right by virtue or by availing of any provision of the Indenture to institute any action or proceeding at law or in equity or in bankruptcy or otherwise upon or under or with respect to the Indenture, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless (i) such holder previously shall have given to the Trustee written notice of default and of the continuance thereof, as hereinbefore provided; (ii) the Holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding shall have made written request upon the Trustee to institute such action or proceedings in its own name as trustee hereunder; (iii) such Holder or Holders shall have offered to the Trustee such indemnity as it may reasonably require against the costs, expenses and liabilities to be incurred in compliance with such request; (iv) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such action or proceeding; and (v) no direction inconsistent with such written request shall have been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Securities of such Series then Outstanding. It is understood and intended, and expressly covenanted by the taker and Holder of every Security with every other taker and Holder and the Trustee, that no one or more Holders of any series shall have any right in any manner whatever by virtue or by availing of any provision of the Indenture to affect, disturb or prejudice the rights of any other such Holder, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under the Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of the applicable series. For the protection and enforcement of the provisions of this Section, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 4.07 Unconditional Right of Holders to Institute Certain Suits. Notwithstanding any other provision in the Indenture and any provision of any Security, the right of any Holder of any Security to receive payment of the principal of and interest on such Security on or after the respective due dates expressed in such Security, or to institute suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 4.08 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default. Except as provided in Section 4.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right

24

and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

No delay or omission of the Trustee or of any Holder to exercise any right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or an acquiescence therein; and, subject to Section 4.06, every power and remedy given by the Indenture or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

Section 4.09 Control by Holders. The Holders of a majority in aggregate principal amount of the Securities of each series affected (voting as one class) at the time Outstanding shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to the Securities of such series by the Indenture; provided, however, that such direction shall not be otherwise than in accordance with law and the provisions of the Indenture. Subject to the provisions of Section 5.01, the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall determine that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith shall determine that the action or proceedings so directed would involve the Trustee in personal liability or if the Trustee in good faith shall determine that the actions or forbearances specified in or pursuant to such direction would be unduly prejudicial to the interests of Holders of the Securities of all series so affected not joining in the giving of said direction, it being understood that (subject to Section 5.01) the Trustee shall have no duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders.

Nothing in the Indenture shall impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction or directions by Holders.

Section 4.10 Waiver of Past Defaults. Except as otherwise provided in Sections 4.01, 4.07 and 7.02 the Holders of a majority in principal amount of the Outstanding Securities of any series (voting as one class) may, by notice to the Trustee, on behalf of the Holders of all Securities of such series waive an existing Default and its consequences. Upon such waiver, the Default will cease to exist, and any Event of Default arising therefrom will be deemed to have been cured, but no such waiver will extend to any subsequent or other Default or impair any right consequent thereon.

Section 4.11 Trustee to Give Notice of Default, But May Withhold in Certain Circumstances. The Trustee shall give to the Holders of any series, as the names and addresses of such Holders appear on the registry books, notice by mail of all defaults known to a Responsible Officer of the Trustee which have occurred with respect to such series, such notice to be transmitted within 45 days after the occurrence thereof, unless such defaults shall have been cured before the giving of such notice (the term “default” or “defaults” for the purposes of this section being hereby

25

defined to mean any event or condition which is, or with notice or lapse of time or both would become, an Event of Default); provided that, except in the case of default in the payment of the principal of or interest on any of the Securities of such series, or in the payment of any sinking or purchase fund installment with respect to the Securities of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors or trustees and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders of such series.

Section 4.12 Right of Court to Require Filing of Undertaking to Pay Costs. In any suit for the enforcement of any right or remedy under the Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorneys fees, against any party litigant (other than the Trustee) in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by a Holder to enforce payment of principal of or interest on any Security on the respective due dates, or a suit by Holders of more than 10% in principal amount of the Outstanding Securities.

ARTICLE 5

CONCERNING THE TRUSTEE

Section 5.01 Duties and Responsibilities of the Trustee; During Default; Prior to Default. (a) The duties and responsibilities of the Trustee are as provided by the Trust Indenture Act and as set forth herein. Whether or not expressly so provided, every provision of the Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee is subject to this Article.

(b) Except during the continuance of an Event of Default, the Trustee need perform only those duties that are specifically set forth in the Indenture and no others, and no implied covenants or obligations will be read into the Indenture against the Trustee. In case an Event of Default of which a Responsible Officer shall have actual knowledge or shall have received written notice from the Company or any holder of Securities of any series has occurred and is continuing, the Trustee shall exercise those rights and powers vested in it by the Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

(c) No provision of the Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct.

Section 5.02 Trustee’s Obligations with Respect to the Covenants. The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with the covenants contained in Article 4 or with respect to any reports or other documents filed under the Indenture; provided, however, that nothing herein shall relieve the Trustee of any obligations to monitor the Company’s timely delivery of all reports and certificates required under Section 3.04 of the Indenture and to fulfill its obligations under Article 5 hereof.

26

Section 5.03 Moneys Held by Trustee. Subject to the provisions of Section 9.06 hereof, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. Neither the Trustee nor any agent of the Company or the Trustee shall be liable for interest on any money received by it hereunder except such as it may agree with the Company in writing to pay thereon.

Section 5.04 Reports by the Trustee to Holders. The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under the Indenture as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant thereto.

Reports so required to be transmitted at stated intervals of not more than 12 months shall be transmitted no later than July 15 in each calendar year, commencing with the first July 15 after the first issuance of Securities pursuant to the Indenture.

A copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with any stock exchange upon which any Securities are listed, with the Commission and with the Company.

Section 5.05 Certain Rights of the Trustee. Subject to Trust Indenture Act Sections 315(a) through (d):

(a) In the absence of bad faith on its part, the Trustee may rely, and will be protected in acting or refraining from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document, but, in the case of any document which is specifically required to be furnished to the Trustee pursuant to any provision hereof, the Trustee shall examine the document to determine whether it conforms to the requirements of the Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). The Trustee, in its discretion, may make further inquiry or investigation into such facts or matters as it sees fit.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel conforming to Section 10.05 and the Trustee will not be liable for any action it takes or omits to take in good faith in reliance on the certificate or opinion.

(c) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any attorney or agent appointed by the Trustee with due care.

27

(d) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by the Indenture or to institute, conduct or defend any litigation hereunder or in relation hereto at the request or direction of any of the Holders, unless such Holders have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

(e) The Trustee will not be liable in its individual capacity for any action it takes, suffers or omits to take in good faith that it believes to be authorized or within its rights or powers or for any action it takes or omits to take in accordance with the direction of the Holders in accordance with Section 4.09 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under the Indenture.

(f) The Trustee may consult with counsel, and any advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(g) No provision of the Indenture will require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of its duties hereunder, or in the exercise of its rights or powers, unless it receives indemnity satisfactory to it against any loss, liability or expense.

(h) The Trustee shall not be liable in its individual capacity for an error in judgment made in good faith by a Responsible Officer or other officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts.

(i) The Trustee shall not be personally liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by the Indenture.

(j) The Trustee shall have no duty to see to any recording, filing or depositing of the Indenture or any agreement referred to herein or any financing statement or continuation statement evidencing a security interest, or to see to the maintenance of any such re-recording or re-filing or re-depositing thereof.

(k) The Trustee shall not be required to take notice or be deemed to have notice or knowledge of any default or Event of Default unless a Responsible Officer of the Trustee shall have received written notice from the Company or any holder of the Securities or obtained actual knowledge thereof. In the absence of receipt of such notice or actual knowledge, the Trustee may conclusively assume that there is no default or Event of Default.

Section 5.06 Trustee and Agents May Hold Securities; Collections, etc. The Trustee or any agent of the Company or the Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not the Trustee or such agent and may otherwise deal with the Company and receive, collect, hold and retain collections from the Company with the same rights it would have if it were not the Trustee or such agent.

28

Section 5.07 Compensation and Indemnification of Trustee and Its Prior Claim. (a) The Company will pay the Trustee compensation as agreed upon in writing for its services. The compensation of the Trustee is not limited by any law on compensation of a Trustee of an express trust. The Company will reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred or made by the Trustee, (including the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ) except to the extent any such expense, disbursement or advance may arise from its negligence or bad faith. The Company also covenants to indemnify the Trustee, its directors, officers, employees and agents and each predecessor Trustee, its directors, officers, employees and agents for, and to hold each of them harmless against, any loss, liability or expense arising out of or in connection with the acceptance or administration of the Indenture or the trusts hereunder and the performance of its duties hereunder and under the Securities, including the costs and expenses of defending itself against or investigating any claim of liability and of complying with any process served upon it or any of its officers, except to the extent such loss liability or expense is due to the negligence or bad faith of the Trustee or such predecessor Trustee.

Anything in the Indenture to the contrary notwithstanding, in no event shall the Trustee be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits).

(b) To secure the Company’s payment obligations in this Section, the Trustee will have a lien prior to the Securities on all money or property held or collected by the Trustee, in its capacity as Trustee, except money or property held in trust to pay principal of, and interest on particular Securities.

The obligations of the Company under this Section 5.07 shall survive the resignation and removal of the Trustee and payment of the Securities, and shall extend to any co-trustee or separate trustee.

Section 5.08 Right of Trustee to Rely on Officers’ Certificate, etc. Subject to Sections 5.01 and 5.05, whenever in the administration of the trusts of the Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of the Indenture upon the faith thereof.

Section 5.09 Disqualification; Conflicting Interests. If the Trustee has or shall acquire any “conflicting interest” within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the Company shall in all respects comply with the provisions of Section 310(b) of the Trust Indenture Act.

29

Section 5.10 Persons Eligible for Appointment as Trustee. The Indenture must always have a Trustee that satisfies the requirements of Trust Indenture Act Section 310(a) and has a combined capital and surplus of at least $25,000,000 as set forth in its most recent published annual report of condition.

Section 5.11 Resignation and Removal; Appointment of Successor Trustee. (a) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign with respect to one or more or all series of Securities by giving written notice of resignation to the Company and by mailing notice thereof by first class mail to Holders of the applicable series of Securities at their last addresses as they shall appear on the Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee or trustees with respect to the applicable series by written instrument in duplicate, executed by authority of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee or trustees. If no successor trustee shall have been so appointed with respect to any series and have accepted appointment within 30 days after the mailing of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide Holder of a Security or Securities of the applicable series for at least six months may, subject to the provisions of Section 4.12, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any of the following shall occur:

(i) the Trustee shall fail to comply with the provisions of Section 310(b) of the Trust Indenture Act with respect to any series of Securities after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security or Securities of such series for at least six months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 310(a) of the Trust Indenture Act and shall fail to resign after written request therefor by the Company or by any Holder; or

(iii) the Trustee shall become incapable of acting with respect to any series of Securities, or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee with respect to the applicable series of Securities and appoint a successor trustee for such series by written instrument, in duplicate, executed by order of the Board of Directors of the Company, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or any Holder who has

30

been a bona fide Holder of a Security or Securities of such series for at least six months may on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee with respect to such series. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(c) The Holders of a majority in aggregate principal amount of the Securities of each series at the time Outstanding may at any time remove the Trustee with respect to Securities of such series and appoint a successor trustee with respect to the Securities of such series with the consent of the Company by delivering to the Trustee so removed, to the successor trustee so appointed and to the Company the evidence provided for in Section 6.01 of the action in that regard taken by the Holders.

(d) Any resignation or removal of the Trustee with respect to any series and any appointment of a successor trustee with respect to such series pursuant to any of the provisions of this Section 5.11 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 5.12.

(e) Any successor trustee appointed pursuant to this Section may be appointed with respect to the Securities of one or more series or all of such series, and at any time there shall be only one Trustee with respect to the Securities of any particular series.

Section 5.12 Acceptance of Appointment by Successor. Any successor trustee appointed as provided in Section 5.11 shall execute and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee with respect to all or any applicable series shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all rights, powers, duties and obligations with respect to such series of its predecessor hereunder, with like effect as if originally named as trustee for such series hereunder; but, nevertheless, on the written request of the Company or of the successor trustee, upon payment of its charges then unpaid, the trustee ceasing to act shall, subject to Section 9.06, pay over to the successor trustee all moneys at the time held by it hereunder and shall execute and deliver an instrument transferring to such successor trustee all such rights, powers, duties and obligations.

If a successor trustee is appointed with respect to the Securities of one or more (but not all) series, the Company, the predecessor Trustee and each successor trustee with respect to the Securities of any applicable series shall execute and deliver an indenture supplemental hereto prepared by and at the expense of the Company which (1) shall contain such provisions as shall be deemed necessary or desirable to transfer and confirm to, and to vest in, each successor trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor trustee relates, (2) shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the predecessor Trustee with respect to the Securities of any series as to which the predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee, and

31

(3) shall 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 hereunder by more than one trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such trustees co-trustees of the same trust and that each such trustee shall be trustee of a trust or trusts under separate indentures.

Upon acceptance of appointment by any successor trustee as provided in this Section 5.12, the Company shall mail notice thereof by first-class mail to the Holders of any series for which such successor trustee is acting as trustee at their last addresses as they shall appear in the Register. If the acceptance of appointment is substantially contemporaneous with the resignation, then the notice called for by the preceding sentence may be combined with the notice called for by Section 5.11. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company.

Section 5.13 Merger, Conversion, Consolidation or Succession to Business of Trustee. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation or national banking association, the resulting, surviving or transferee corporation or national banking association without any further act will be the successor Trustee with the same effect as if the successor Trustee had been named as the Trustee in the Indenture.

In case at the time such successor to the Trustee shall succeed to the trusts created by the Indenture any of the Securities of any series shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee and deliver such Securities so authenticated; and, in case at that time any of the Securities of any series shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificate shall have the full force which it is anywhere in the Securities of such series or in the Indenture provided that the certificate of the Trustee shall have; provided, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities of any series in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 5.14 Preferential Collection of Claims Against the Company. The Trustees shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship described in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent included therein.

ARTICLE 6

CONCERNING THE HOLDERS

Section 6.01 Evidence of Action Taken by Holders. Any request, demand, authorization, direction, notice, consent, waiver or other action provided by the Indenture to be given or taken by a specified percentage in principal amount of the Holders of any or all series may be embodied in and

32

evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee.

If the Company shall solicit from the Holders of any series any request, demand, authorization, direction, notice, consent, waiver or other action, the Company may, at its option, as evidenced by an Officers’ Certificate, fix in advance a record date for such series for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other action, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action, may be given before or after the record date, but only the Holders of the requisite proportion of Outstanding Securities of that series who have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action, and for that purpose the Outstanding Securities of that series shall be computed as of the record date; provided, however, that no such authorization, agreement or consent by such Holders on the record date shall be deemed effective unless it shall become effective pursuant to the provisions of the Indenture not later than six months after the record date.

Proof of execution of any instrument or of a writing appointing any such agent shall be sufficient for any purpose of the Indenture and (subject to Sections 5.01 and 5.05) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Article.

Section 6.02 Proof of Execution of Instruments and of Holding of Securities; Record Date. Subject to Sections 5.01 and 5.05, the execution of any instrument by a Holder or his agent or proxy may be proved in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Securities shall be proved by the Register or by a certificate of the registrar thereof. The Company may set a record date for purposes of determining the identity of Holders of any series entitled to vote or consent to any action referred to in Section 6.01, which record date may be set at any time or from time to time by notice to the Trustee, for any date or dates (in the case of any adjournment or reconsideration) not more than 60 days nor less than five days prior to the proposed date of such vote or consent, and thereafter, notwithstanding any other provisions hereof, only Holders of such series of record on such record date shall be entitled to so vote or give such consent or revoke such vote or consent. Notice of such record date may be given before or after any request for any action referred to in Section 6.01 is made by the Company.

Section 6.03 Holders to Be Treated as Owners. Prior to the due presentment for registration of transfer of any Security, the Company, the Trustee and any agent of the Company or the Trustee may deem and treat the person in whose name any Security shall be registered upon the Register for such series as the absolute owner of such Security (whether or not such Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of, and, subject to the provisions of the Indenture, interest on such Security and for all other purposes; and neither the Company, the Trustee,

33

nor any agent of the Company or the Trustee shall be affected by any notice to the contrary. All such payments so made to any such person, or upon his order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Security.

Section 6.04 Securities Owned by Company Deemed Not Outstanding. In determining whether the Holders of the requisite aggregate principal amount of Outstanding Securities of any or all series have concurred in any direction, consent or waiver under the Indenture, Securities which are owned by the Company or any other obligor on the Securities with respect to which such determination is being made or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the Securities with respect to which such determination is being made shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver only Securities which a Responsible Officer of the Trustee actually knows are so owned, or has received written notice that such Securities are so owned, shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company or any other obligor upon the Securities or any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the Securities. In case of a dispute as to such right, the advice of counsel shall be full protection in respect of any decision made by the Trustee in accordance with such advice. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Securities, if any, known by the Company to be owned or held by or for the account of any of the above-described persons; and, subject to Sections 5.01 and 5.05, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Securities not listed therein are Outstanding for the purpose of any such determination.

The Trustee, subject to the provisions of Sections 5.01 and 5.05, may receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any amendment, supplemental indenture or waiver executed pursuant to this Article 7 complies with the applicable provisions of the Indenture; provided, however, that such Officers’ Certificate and Opinion of Counsel need not be provided in connection with the execution of an amendment, supplemental indenture or waiver that establishes the terms of a series of Securities pursuant to Section 2.01 hereof.

ARTICLE 11

REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS

Section 11.01 Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series which are redeemable before their maturity or to any sinking fund for the retirement of Securities of a series except as otherwise specified as contemplated by Section 2.03 for Securities of such series.

Section 11.02 Notice of Redemption; Partial Redemptions. Except as otherwise contemplated by Section 2.03 of the Indenture, notice of redemption to the Holders of any series to be redeemed as a whole or in part at the option of the Company shall be given by mailing notice of such redemption by first class mail, postage prepaid, at least 30 days and not more than 60 days prior to the date fixed for redemption to such Holders of such series at their last addresses as they shall appear upon the registry books. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives the notice. Failure to give notice by mail, or any defect in the notice to the Holder of any Security of a series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Security of such series.

The notice of redemption to each such Holder shall specify the principal amount of each Security of such series held by such Holder to be redeemed, the date fixed for redemption, the redemption price, the place or places of payment, that payment will be made upon presentation and surrender of such Securities, that such redemption is pursuant to the mandatory or optional sinking fund, or both, if such be the case, that interest accrued to the date fixed for redemption will be paid

45

as specified in such notice and that on and after said date interest thereon or on the portions thereof to be redeemed will cease to accrue. In case any Security of a series is to be redeemed in part only the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Security, a new Security or Securities of such series in principal amount equal to the unredeemed portion thereof will be issued.

The notice of redemption of Securities of any series to be redeemed shall be prepared and given by the Company or, at the Company’s request, prepared by the Company and given by the Trustee in the name and at the expense of the Company; provided, the Company has provided the notice to the Trustee at least three (3) Business Days prior to the date by which such notice must be sent to the Holders.

If less than all the Securities of a series are to be redeemed, the Securities to be redeemed shall be selected by lot by the Depositary in the case of Securities represented by a Global Security, or, in the case of Securities not represented by a Global Security, the Trustee shall select, in such manner as it shall deem appropriate and fair, Securities of such series to be redeemed in whole or in part. Securities may be redeemed in part in multiples equal to the minimum authorized denomination for Securities of such series or any multiple thereof. The Trustee shall promptly notify the Company in writing of the Securities of such series selected for redemption and, in the case of any Securities of such series selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of the Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities of any series shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

At least one Business Day prior to the redemption date specified in the notice of redemption given as provided in this Section, the Company will deposit with the Trustee or with one or more paying agents (or, if the Company is acting as its own paying agent, set aside, segregate and hold in trust as provided in Section 3.03) an amount of money sufficient to redeem on the redemption date all the Securities of such series so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for redemption.

Section 11.03 Payment of Securities Called for Redemption. If notice of redemption has been given as above provided, the Securities or portions of Securities specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, together with interest accrued to the date fixed for redemption, and on and after said date (unless the Company shall default in the payment of such Securities at the redemption price, together with interest accrued to said date) interest on the Securities or portions of Securities so called for redemption shall cease to accrue and such Securities shall cease from and after the date fixed for redemption to be entitled to any benefit or security under the Indenture, and the Holders thereof shall have no right in respect of such Securities except the right to receive the redemption price thereof and unpaid interest to the date fixed for redemption. On presentation and surrender of such Securities at a place of payment specified in said notice, said Securities or the specified

portions thereof shall be paid and redeemed by the Company at the applicable redemption price, together with interest accrued thereon to the date fixed for redemption; provided that any payment of interest becoming due on or before the date fixed for redemption shall be payable to the Holders of such Securities registered as such on the relevant record date.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid or duly provided for, bear interest from the date fixed for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue Discount Security) borne by the Security.

Upon presentation of any Security redeemed in part only, the Company shall execute and the Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the expense of the Company, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so presented.

Section 11.04 Exclusion of Certain Securities from Eligibility for Selection for Redemption. Securities shall be excluded from eligibility for selection for redemption if they are identified by registration and certificate number in a written statement signed by an authorized officer of the Company and delivered to the Trustee at least 15 days prior to the last date on which notice of redemption may be given as being owned of record and beneficially by, and not pledged or hypothecated by either (a) the Company or (b) an entity specifically identified in such written statement directly or indirectly controlling or controlled by or under direct or indirect common control with the Company.
