Any Warrants constituting a part of the Units of any series shall be executed on behalf of the Company in accordance with the terms of the Warrant Agreement.

Section 2.07. Temporary Unit Certificates. Pending the preparation of Unit Certificates for any series, the Company may execute and deliver to the Trustee and/or the Warrant Agent, as appropriate, and the Trustee and/or the Warrant Agent, as appropriate, shall authenticate, countersign and deliver, as appropriate, in lieu of such Unit Certificates, temporary Unit Certificates for such series. Temporary Unit Certificates shall be in substantially the form of the Unit Certificates of such series, but with such omissions, insertions and variations as may be appropriate for temporary Unit Certificates, all as may be determined by the Company with the concurrence of the Trustee, Warrant Agent and/or Agent, as appropriate, as evidenced by the execution and authentication and/or countersignature of the Securities constituting a part of the Units evidenced thereby, as applicable.

If temporary Unit Certificates for any series are issued, the Company will cause definitive Unit Certificates for such series to be prepared without unreasonable delay. After the preparation of such definitive Unit Certificates, the temporary Unit Certificates shall be exchangeable therefor upon surrender of temporary Registered Units of such series at the Corporate Trust Office, at the expense of the Company and without charge to any Holder and, in the case of Unregistered Units, at any agency maintained for such purpose as specified pursuant to Section 2.03. Upon surrender for cancellation of any one or more temporary Unit Certificates, the Company shall execute and deliver to the Trustee, the Warrant Agent and/or the Agent, and the Trustee and/or the Warrant Agent shall authenticate or countersign and deliver, as appropriate, in exchange therefor definitive Unit Certificates of the same series of like tenor, of authorized denominations and evidencing a like number of Units as the temporary Unit Certificate or Certificates so surrendered. Until so exchanged, the temporary Unit Certificates of any series shall in all respects evidence the same benefits and the same obligations under any Notes or Pre-Paid Purchase Contracts or Warrants constituting parts of such Units, the Indenture, the Warrant Agreement and this Agreement as definitive Unit Certificates of such series, unless otherwise specified pursuant to Section 2.03

Section 2.08. Registration of Transfer and Exchange; Global Units. The Agent shall keep at its Corporate Trust Office for each series of Registered Units a register (the register maintained in such office being herein referred to as the “Unit Register”) in which, subject to such reasonable regulations as it may prescribe, the Agent shall provide for the registration of the Units of any series.

At the option of the Holder thereof, Registered Units of any series (other than a registered Global Unit, except as set forth below) may be transferred or exchanged for a Registered Unit or Registered Units of such series having authorized denominations evidencing the number of Units transferred or exchanged, upon surrender of such Registered Units to be so transferred or exchanged at the Corporate Trust Office of the Agent upon payment, if the Company shall so require, of the charges hereinafter provided. If the Units of any series are issued in both registered and unregistered form, except as otherwise specified pursuant to Section 2.03, at the option of the Holder thereof, Unregistered Units of such series may be exchanged for Registered Units of such series having authorized denominations and evidencing the number of Units transferred or exchanged, upon surrender of such Unregistered Units to be so transferred or exchanged at the Corporate Trust Office of the Agent and upon payment, if the Company shall so require, of the charges hereinafter provided. At the option of the Holder thereof, if Unregistered Units of any series are issued in more than one authorized denomination, except as otherwise specified pursuant to Section 2.03, such Unregistered Units may be exchanged for Unregistered Units of such series having authorized denominations evidencing the number of Units exchanged, upon surrender of such Unregistered Units to be so exchanged at the Corporate Trust Office of the Agent or as specified pursuant to Section 2.03, and upon payment, if the Company shall so require, of the charges hereinafter provided. Unless otherwise specified pursuant to Section 2.03, Registered Units of any series may not be exchanged for Unregistered Units of such series. Whenever any Units are so surrendered for transfer or exchange, the Company shall execute, and the Trustee and/or Warrant Agent, as appropriate, shall authenticate and/or countersign, as the case may be, and deliver the Units which the Holder making the transfer or exchange is entitled to receive. All Units (including the Securities constituting part of such Units) surrendered upon any exchange or transfer provided for in this Agreement shall be promptly cancelled and disposed of by the Agent and the Agent will deliver a certificate of disposition thereof to the Company and to the Trustee and the Warrant Agent, as applicable.

Unregistered Units shall be transferable by delivery.

Subject to Section 2.12, if the Company shall establish pursuant to Section 2.03 that the Units of a series are to be evidenced by one or more Global Units, then the Company shall execute and the Warrant Agent and Trustee shall, in accordance with this Section and Section 2.06, countersign and authenticate, as appropriate, and deliver one or more Global Unit Certificates that (i) shall evidence all or a portion of the Units of such series issued in such form and not yet cancelled, (ii) in the case of Registered Units, shall be registered in the name of the Depositary for such Units or the nominee of such Depositary, (iii) shall be delivered by the Agent to the Depositary for such Units or pursuant to such Depositary’s instructions and (iv) in the case of Registered Units, shall bear a legend substantially to the following effect: “Unless and until it is exchanged in whole or in part for Units in definitive registered form, this Unit Certificate may

not be transferred except as a whole by the Depositary to the nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.” Whenever Global Units of any series are exchanged for Definitive Units of such series or whenever Definitive Units of any series are exchanged for Global Units of such series, the Agent shall cause, as applicable: (i) Schedule A of the Global Note, if any, to be endorsed to reflect any increase or decrease, as the case may be, in the principal amount of the Note, if any, that are comprised by Global Units as a result of such exchange, (ii) Schedule A of the Global Pre-Paid Purchase Contract, if any, be endorsed to reflect any increase or decrease, as the case may be, in the number of Pre-Paid Purchase Contracts, if any, that are comprised by the Global Units as a result of such Exchange and (iii) Schedule A of the Global Warrant, if any, to be endorsed to reflect any increase or decrease, as the case may be, in the number of Warrants, if any, that are comprised by the Global Units as a result of such exchange.

All Unit Certificates authenticated, countersigned and executed upon any registration of transfer or exchange of a Unit Certificate shall evidence the ownership of the principal amount of Note, if any, specified therein or on the face thereof or otherwise evidenced thereby, the number of Pre-Paid Purchase Contracts, if any, specified therein or on the face thereof or otherwise evidenced thereby and the number of Warrants, if any, specified therein or on the face thereof or otherwise evidenced thereby and shall be entitled to the same benefits, and be subject to the same obligations, under the Indenture, the Warrant Agreement and this Agreement as the Units evidenced by the Unit Certificate surrendered upon such registration of transfer or exchange.

Every Unit Certificate presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Agent, duly executed by the Holder thereof or his attorney duly authorized in writing. Except as otherwise provided herein with respect to the Units, the Agent shall register the transfer or exchange of any outstanding Unit Certificate upon the Unit Register at its Corporate Trust Office.

No service charge shall be made for any transfer or exchange of a Unit, but the Company and the Agent may require payment from the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Units, other than any exchanges pursuant to Section 2.09 not involving any transfer.

Notwithstanding the foregoing, and subject to Section 2.08 of the Indenture, the Company shall not be obligated to execute and deliver to the Trustee, the Warrant Agent or the Agent, and none of the Trustee, under the terms of the Indenture, or the Warrant Agent, under the terms of the Warrant Agreement, shall be obligated to authenticate or countersign any Unit Certificate presented or

surrendered for registration of transfer or for exchange of any Note, Pre-Paid Purchase Contract or Warrant evidenced thereby or any Unit Certificate evidencing a Definitive Unit to be issued in exchange for interests in Global Units or to reflect any increase or decrease in a Global Unit, Global Note, Pre-Paid Purchase Contract or Global Warrant (i) during the period beginning any time on or after the opening of business 15 days before the day of mailing of a notice of redemption or of any other exercise of any right held by the Company with respect to the Unit (or any Security constituting a part of the Units of such series) and ending at the close of business on the day of the giving of such notice, (ii) that evidences or would evidence any such Unit or Security selected or called for redemption or with respect to which such right has been exercised or (iii) at any other date specified pursuant to Section 2.03.

Section 2.09. Mutilated, Destroyed, Lost and Stolen Unit Certificates. If any mutilated Unit Certificate is surrendered to the Agent, the Company shall execute and deliver to the Trustee and the Warrant Agent, as appropriate, and the Trustee and the Warrant Agent shall authenticate, countersign and deliver, as appropriate, in exchange therefor new Securities comprised by Units of the same series, of like tenor and evidenced by a new Unit Certificate evidencing the same number of Units and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee and the Warrant Agent and/or the Agent, as appropriate, (i) evidence to their satisfaction of the destruction, loss or theft of any Unit Certificate and (ii) such security or indemnity as may be required by them to hold each of them and any agent of any of them harmless, then, in the absence of notice to the Company and the Trustee and the Warrant Agent as appropriate, that such Unit Certificate has been acquired by a bona fide purchaser, the Company shall execute and deliver to the Trustee and the Warrant Agent and/or the Agent, as appropriate, and the Trustee (in accordance with the provisions of the Indenture) and the Warrant Agent (in accordance with the provisions of the Warrant Agreement) shall authenticate and countersign and the Agent shall deliver to the Holder, as appropriate, in lieu of any such destroyed, lost or stolen Unit Certificate, new Securities comprised by Units of the same series, of like tenor and evidenced by a new Unit Certificate evidencing the same number of Units and bearing a number not contemporaneously outstanding.

Unless otherwise specified pursuant to Section 2.03, notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Trustee, the Warrant Agent or the Agent, and none of the Trustee (under the Indenture), the Warrant Agent (under the Warrant Agreement), or the Agent shall be obligated to authenticate, countersign or deliver to the Holder, a new Unit Certificate (or any Security constituting a part of such Unit) under this Section 2.09 (i) during the period beginning any time on or after the opening of business 15 days before the day of mailing of a notice of redemption or of any other exercise of any right held by the Company with respect to the Unit (or any Security constituting a part of such Unit) and ending at the close of business on the day of the giving of such notice, (a) that evidences any Unit or Security

selected or called for redemption or with respect to which such right has been exercised, or (b) at any other date specified pursuant to Section 2.03. In lieu of delivery of a new Unit Certificate, upon satisfaction of the applicable conditions specified in clauses (i) and (ii) of the preceding paragraph, the Agent shall deliver or cause to be delivered on the applicable redemption date, exercise date or settlement date for Pre-Paid Purchase Contracts, (i) in respect of Notes, Warrants or Pre-Paid Purchase Contracts constituting a part of the Units evidenced by such Unit Certificate that are selected or called for redemption, the redemption price of such Notes, Warrants or Pre-Paid Purchase Contracts or (ii) in respect of Warrants constituting a part of the Units evidenced by such Unit Certificate with respect to which exercise of any such right has taken place, (x) the amount deliverable with respect to such Warrants or (y) if a default under the Warrant Agreement or Warrant has occurred by virtue of the Company’s having failed to deliver the amount deliverable against, in the case of any such Warrants, tender by the Agent of the exercise price or other amount, as the case may be, such amount, if any, received by the Agent from the Holder in respect of exercise of such Warrants.

Upon the issuance of any new Unit Certificate under this Section, the Company and the Agent 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 Agent) connected therewith.

Every new Unit Certificate executed pursuant to this Section in lieu of any destroyed, lost or stolen Unit Certificate shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Unit Certificate (and the Securities evidenced thereby) shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Unit Certificates delivered hereunder.

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

Section 2.10. Persons Deemed Owners.

(a) Prior to due presentment of a certificate evidencing a Registered Unit of any series for registration of transfer, the Company, the Trustee, the Warrant Agent and the Agent, as appropriate, and any agent of the Company, the Trustee, the Warrant Agent or the Agent, as appropriate, may treat the Person in whose name any Registered Security evidenced by such Unit Certificate is registered as the owner of the Units evidenced thereby for all purposes whatsoever, whether or not payment with respect to any Security constituting a part of the Units evidenced thereby shall be overdue and notwithstanding any notice to the contrary. None of the Company, the Trustee, the Warrant Agent, the

Agent or any agent of the Company, the Trustee, the Warrant Agent or the Agent shall be affected by notice to the contrary.

(b) The Company, the Trustee, the Warrant Agent and the Agent, as appropriate, and any agent of the Company, the Trustee, the Warrant Agent or the Agent, as appropriate, may treat the bearer of a certificate evidencing an Unregistered Unit as the absolute owner of the Units evidenced thereby for all purposes whatsoever whether or not payment with respect to any Security constituting a part of the Units evidenced thereby shall be overdue and notwithstanding any notice to the contrary. None of the Company, the Trustee, the Warrant Agent, the Agent or any agent of the Company, the Trustee, the Warrant Agent or the Agent shall be affected by notice to the contrary.

Section 2.11. Cancellation. All Unit Certificates surrendered for payment, and all Unit Certificates surrendered for redemption of any Notes or Pre-Paid Purchase Contracts or exercise of any Warrants evidenced thereby shall, if surrendered to any Person other than the Trustee, the Warrant Agent or the Agent, as appropriate, be delivered to the Trustee, the Warrant Agent and/or the Agent, as appropriate, and, if not already cancelled, any Note, Pre-Paid Purchase Contract or Warrant evidenced by such Units shall be promptly cancelled by the Trustee, the Warrant Agent and/or the Agent, as appropriate. The Company may at any time deliver to the Trustee, the Warrant Agent and/or the Agent, as appropriate, for cancellation any Unit Certificates previously authenticated, countersigned and delivered hereunder, under the Warrant Agreement and under the Indenture, which the Company may have acquired in any manner whatsoever, and all Unit Certificates so delivered shall, upon Issuer Order of the Company, be promptly cancelled by the Trustee, Warrant Agent and/or the Agent, as appropriate. No Unit Certificates shall be authenticated and countersigned in lieu of or in exchange for any Unit Certificates cancelled as provided in this Section, except as permitted by this Agreement.

If the Company or any Affiliate of the Company shall acquire any Unit Certificate, such acquisition shall not operate as a cancellation of such Unit Certificate unless and until such Unit Certificate is delivered to the Trustee, the Warrant Agent and/or the Agent, as appropriate, for the purpose of cancellation.

Section 2.12. Exchange of Global Units and Definitive Units. In the case of Registered Units, Holders of Global Units of any series shall receive Definitive Units of such series in exchange for interests in such Global Units if DTC notifies the Company that it is unwilling or unable to continue as Depositary with respect to the Global Units of such series or if at any time it ceases to be a clearing agency under the Exchange Act, and a successor Depositary registered as a clearing agency under the Exchange Act is not appointed by the Company within

90 days after receipt of such notice or after it becomes aware that DTC has ceased to be such a clearing agency.

If so provided pursuant to Section 2.03, interests in such Global Units may also be transferred or exchanged for Definitive Units upon the request of the Depositary to the Trustee, the Warrant Agent and/or the Agent, as appropriate, to authenticate and countersign as the case may be, Unit Certificates representing Definitive Units (such request being referred to herein as an “Optional Definitive Unit Request”).

Definitive Units exchanged for interests in Global Units pursuant to this Section 2.12 shall be denominated in the amounts and registered in the name of such Person or Persons as the Depositary shall instruct the Agent, the Warrant Agent and the Trustee, as appropriate.

Whenever Global Units are exchanged for Definitive Units the Agent shall cause Schedule A of the Global Unit to be endorsed to reflect any decrease in the Global Units as a result of such exchange, whereupon the Global Unit Certificate or Certificates shall be canceled and disposed of in accordance with Section 2.11.

If so specified pursuant to Section 2.03, Holders of Definitive Units may transfer or exchange such Definitive Units for interests in Global Units by depositing the Unit Certificates evidencing such Definitive Units with the Agent and requesting the Agent, the Warrant Agent and the Trustee, as appropriate, to effect such exchange. The Agent shall notify the Depositary of any such exchange and, upon delivery to the Agent, the Warrant Agent and the Trustee, as appropriate, of the Unit Certificates evidencing the Definitive Units to be so transferred or exchanged, the Agent shall cause Schedule A of the Global Unit to be endorsed to reflect any increase in the Global Units as a result of such exchange, whereupon the Unit Certificate or Certificates evidencing such Definitive Units shall be canceled and disposed of in accordance with Section 2.11 and Unit Certificates evidencing the remaining Definitive Units, if any, will be issued in accordance with Section 2.08.

ARTICLE 3

Section 5.05. Compensation and Reimbursement. The Company agrees:

(a) to pay to the Agent from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by

any provision of law with regard to the compensation of a trustee of an express trust);

The obligations of the Company under this Section to compensate and indemnify the Agent and any predecessor Agent and to pay or reimburse the Agent and any predecessor Agent for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the resignation or removal of such Agent or predecessor Agent or the termination hereof. Such additional indebtedness shall be a senior claim to that of the Units upon all property and funds held or collected by the Agent as such, except funds held in trust for the benefit of the Holders of particular Units, and the Units are hereby subordinated to such senior claim.

Section 5.06. Corporate Agent Required; Eligibility. There shall at all times be an Agent hereunder which shall be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, having, together with its parent, a combined capital and surplus of at least $50,000,000, subject to supervision or examination by Federal, State or District of Columbia authority and willing to act on reasonable terms. If such corporation, or its parent, publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The Agent hereunder shall at all times be the Trustee under the Indenture and the Warrant Agent under the Warrant Agreement, subject to receipt of an Opinion of Counsel that the same Person is precluded by law from acting in such capacities. If at any time the Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

(b) The Agent may resign by giving written notice thereof to the Company and the Holders, in accordance with Section 7.06 and Section 7.07, 60 days prior to the effective date of such resignation. The Agent may be removed at any time upon 60 days’ notice by the filing with it of an instrument in writing signed on behalf of the Company and specifying such removal and the date when it is intended to become effective. If the instrument of acceptance by a successor Agent required by Section 5.08 shall not have been delivered to the Agent within 30 days after the giving of such notice of resignation, the resigning Agent may petition any court of competent jurisdiction for the appointment of a successor Agent.

(c) If at any time (i) the Agent shall cease to be eligible under Section 5.06, or shall cease to be eligible as Trustee under the Indenture or as Warrant Agent under the Warrant Agreement, and shall fail to resign after written request therefor by the Company or by any Holder, or (ii) the Agent shall become incapable of acting with respect to the Units or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator of the Agent or of its property shall be appointed or any public officer shall take charge or control of the Agent or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (A) the Company, by Board Resolution, may remove the Agent and appoint a successor Agent, or (B) any Holder who has been a bona fide Holder of a Unit 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 Agent and the appointment of a successor Agent or Agents. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Agent and appoint a successor Agent.

(d) If the Agent shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Agent for any cause, the Company, by Board Resolution, shall promptly appoint a successor Agent or Agents (other than the Company) and shall comply with the applicable requirements of Section 5.08. If no successor Agent shall have been so appointed by the Company and accepted appointment in the manner required by Section 5.08, any Holder who has been a bona fide Holder of a Unit for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Agent.

(e) The Company shall give, or shall cause such successor Agent to give, notice of each resignation and each removal of the Agent and each appointment of a successor Agent to all Holders of Units in accordance with

Section 7.07. Each notice shall include the name of the successor Agent and the address of its Corporate Trust Office.

Section 5.08. Acceptance of Appointment by Successor. (a) In case of the appointment hereunder of a successor Agent, every such successor Agent so appointed shall execute, acknowledge and deliver to the Company and to the retiring Agent an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Agent shall become effective and such successor Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, agencies and duties of the retiring Agent, with like effect as if originally named as Agent hereunder; but, on the request of the Company or the successor Agent, such retiring Agent shall, upon payment of all amounts due and payable to it pursuant to Section 5.05, execute and deliver an instrument transferring to such successor Agent all the rights and powers of the retiring Agent and shall duly assign, transfer and deliver to such successor Agent all property and money held by such retiring Agent hereunder. Any retiring Agent shall, nonetheless, retain a prior claim upon all property or funds held or collected by such Agent to secure any amounts then due it pursuant to Section 5.05.

(b) Upon request of any such successor Agent, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Agent all such rights, powers and agencies referred to in paragraph (a) of this Section.

(c) No successor Agent shall accept its appointment unless at the time of such acceptance such successor Agent shall be eligible under this Article.

(d) Upon acceptance of appointment by any successor Agent as provided in this Section, the Company shall give notice thereof to the Holders of Units in accordance with Section 7.07. If the acceptance of appointment is substantially contemporaneous with the resignation of the Agent, then the notice called for by the preceding sentence may be combined with the notice called for by Section 5.07. If the Company fails to give such notice within ten days after acceptance of appointment by the successor Agent, the successor Agent shall cause such notice to be given at the expense of the Company.

Section 5.09. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Agent shall be a party, or any corporation succeeding to all or substantially all the agency business of the Agent, shall be the successor of the Agent hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation shall be otherwise eligible under this Article.

Section 5.10. Tax Compliance. (a) The Agent, on its own behalf and on behalf of the Company, will comply with all applicable certification, information

reporting and withholding (including “backup” withholding) requirements imposed by applicable United States, federal and New York State tax laws, regulations or administrative practice (i) with respect to payments on, or transfer or redemption of the Notes, the Pre-paid Purchase Contracts or the Warrants or (ii) if specifically instructed by the Company, with respect to the issuance, delivery, holding, or exercise of rights (other than by payment, transfer or redemption) under the Notes, the Pre-paid Purchase Contracts or the Warrants. Such compliance shall include, without limitation, the preparation and timely filing of required returns with respect to, and the timely payment of, all amounts required to be withheld to the appropriate taxing authority or its designated agent. The Company will provide to the Agent such information as it may reasonably request in order to comply with this Section.

(b) The Agent shall comply with any direction received from the Company with respect to the application of such requirements to particular payments or holders or in other particular circumstances, and may for purposes of this Agreement rely on any such direction in accordance with the provisions of Section 5.01(b)(2) hereof.

(c) The Agent shall maintain all appropriate records documenting compliance with such requirements, and shall make such records available on request at reasonable times during normal business hours to the Company or to their authorized representatives duly authorized in writing.

(d) Unless otherwise specified in an applicable pricing supplement, the Company by the issuance and sale of any Unit, and any Holder of a Unit by its acceptance thereof, agree to (in the absence of any applicable administrative ruling or judicial determination to the contrary) treat the Securities that constitute any Unit as separate securities and to file all United States federal, state and local tax returns consistent with the treatment of such Unit as constituted by separate securities. Further, the Company agrees, and the Holders shall be deemed to agree, not to file any tax returns, or take a position with any tax authority, that is inconsistent with the characterization of the Notes as debt for all U.S. federal tax purposes.

(e) Issuances of Unregistered Units will be in accordance with the U.S. federal tax “TEFRA D Rules” as discussed in an applicable pricing supplement.

ARTICLE 6

substantially all of its assets to, any other corporation, provided that (i) the Company shall be the continuing corporation, or the successor corporation (if other than the Company) shall be a corporation organized and existing under the laws of the United States of America, or any state thereof or the District of Columbia, and such corporation shall assume the due and punctual performance and observance of all of the covenants and conditions of this Agreement to be performed by the Company by supplemental agreement in form satisfactory to the Agent executed and delivered to the Agent by such corporation, and (ii) neither the Company nor such successor corporation immediately after such merger or consolidation, or such sale, conveyance or lease shall be in default in the performance of any such covenant or condition.

Section 6.02. Rights and Duties of Successor Company. In case of any such consolidation, merger, sale or conveyance and upon any such assumption by the successor corporation, such successor corporation shall succeed to and be substituted for the Company with the same effect as if it had been named herein as the Company. Such successor corporation thereupon may cause to be signed, and may issue (subject to the provisions of the Indenture and the Warrant Agreement) either in its own name or in the name of Xxxxxx Xxxxxxx any or all of the Notes, Pre-Paid Purchase Contracts and/or Warrants issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Agent; and, upon the order of such successor corporation, instead of the Company, and subject to all the terms, conditions and limitations in this Agreement prescribed, the Trustee, the Warrant Agent and the Agent shall authenticate, countersign and deliver, as applicable, any Notes, Pre-Paid Purchase Contracts or Warrants that previously shall have been signed and delivered by the officers of the Company to the Trustee and the Warrant Agent for authentication and countersignature, and any Notes, Pre-Paid Purchase Contracts and/or Warrants evidencing Units which such successor corporation thereafter shall cause to be signed and delivered to the Trustee and the Warrant Agent for such purpose.

In case of any such consolidation, merger, sale, conveyance or lease such change in phraseology and form (but not in substance) may be made in the Unit Certificates thereafter to be issued as may be appropriate.

ARTICLE 7

Miscellaneous Provisions

Section 7.01. Amendments. (a) This Agreement and the terms of the Units may be amended (by means of an agreement supplemental hereto or otherwise) by the Company and the Agent, without the consent of the Holders, (i)

for the purpose of curing any ambiguity, or of curing, correcting or supplementing any defective or inconsistent provision contained herein or therein, (ii) to evidence and provide for the acceptance of appointment hereunder by a successor Agent with respect to the Units or (iii) in any other manner which the Company may deem necessary or desirable and which will not adversely affect the interests of the affected Holders.

(b) The Company and the Agent may modify or amend this Agreement (by means of an agreement supplemental hereto or otherwise) with the consent of Holders holding not less than a majority in number of the then outstanding Units affected thereby for any purpose; provided, however, that no such modification or amendment that materially and adversely affects the exercise or separation rights of the affected Holders or reduces the percentage of the number of outstanding Units, the consent of the Holders of which is required for modification or amendment of this Agreement, may be made without the consent of each Holder affected thereby. In the case of Units evidenced by one or more Global Unit Certificates, the Company and the Agent shall be entitled to rely upon certification in form satisfactory to each of them that any requisite consent has been obtained from holders of beneficial ownership interests in the relevant Global Unit Certificate. Such certification may be provided by participants of the Depositary acting on behalf of such beneficial owners of Units, provided that any such certification is accompanied by a certification from the Depositary as to the Unit holdings of such participants.

(c) Upon the request of the Company, accompanied by a copy of a Board Resolution (which Board Resolution may provide general terms or parameters for such action and may provide that the specific terms of such action may be determined in accordance with or pursuant to an Officer’s Certificate) authorizing the execution of any such amendment, and upon the filing with the Agent of evidence of the consent of Holders as aforesaid, the Agent shall join with the Company in the execution of such amendment unless such amendment affects the Agent’s own rights, duties or immunities under this Agreement or otherwise, in which case the Agent may in its discretion, but shall not be obligated to, enter into such amendment. In executing, or accepting the additional duties created by, any amendment permitted by this Section, the Agent shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such amendment is authorized or permitted by this Agreement. The fact and date of the execution of any consent of Holders, or the authority of the Person executing the same, may be proved by the certificate of any notary public or other officer of any jurisdiction authorized to take acknowledgments of deeds or administer oaths that the person executing such instruments acknowledged to him the execution thereof, or by an affidavit of a witness to such execution sworn to before any such notary or other such officer. Where such execution is by or on behalf of any legal entity other than an individual, such certificate or affidavit shall also constitute sufficient proof of the authority of the person executing the same. The fact of the holding by any Holder of an Unregistered Unit of any series, and the identifying number of such Unit

and the date of his holding the same, may be proved by the production of such Unit or by a certificate executed by any trust company, bank, banker or recognized securities dealer wherever situated satisfactory to the Agent, if such certificate shall be deemed by the Agent to be satisfactory. Each such certificate shall be dated and shall state that on the date thereof a Unit of such series bearing a specified identifying number was deposited with or exhibited to such trust company, bank, banker or recognized securities dealer by the Person named in such certificate. Any such certificate may be issued in respect of one or more Unregistered Units of one or more series specified therein. The holding by the Person named in any such certificate of any Unregistered Units of any series specified therein shall be presumed to continue for a period of one year from the date of such certificate unless at the time of any determination of such holding (1) another certificate bearing a later date issued in respect of the same Units shall be produced, or (2) the Unit of such series specified in such certificate shall be produced by some other Person, or (3) the Units of such series specified in such certificate shall have ceased to be Outstanding. The fact and date of the execution of any such consent and the amount and number of Units of any series held by such Person so executing such consent and the amount and numbers of any Unit or Units for such series may also be proven in accordance with such reasonable rules and regulations as may be prescribed by the Agent or in any other manner which the Agent may deem sufficient. In the case of Registered Units, the ownership of such Units shall be proved by the Unit Register or by a certificate of the Agent, as registrar for the Units. Without limiting the generality of Section 7.01(c), a Clearing System that is or whose nominee or common depositary or a nominee thereof is a Holder of an unregistered Global Unit may allow its accountholders who have beneficial interests in such unregistered Global Note credited to accounts with such Clearing System to direct such Clearing System in taking actions hereunder (through its nominee or common depositary or a nominee thereof) through such Clearing System’s standing instructions and customary practices. The Clearing System shall report only one result of its solicitation of proxies to the Agent.

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

(e) The Company may set a record date for purposes of determining the identity of Holders of Registered Units entitled to consent to any action by consent authorized or permitted hereby. Such record date shall be the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders of Registered Units furnished to the Agent. The ownership of Registered Units shall be proved by the Unit Register.

Section 7.02. Incorporators, Stockholders, Officers and Directors of the Company Immune from Liability. No recourse under or upon any obligation, covenant or agreement contained in this Agreement, or in any Warrant Agreement or any Notes, Pre-Paid Purchase Contracts and/or Warrants, or because of any

indebtedness evidenced thereby, shall be had against any incorporator, or against any past, present or future stockholder, officer, attorney-in-fact or director, as such, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or penalty or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Units by the Holders thereof and as part of the consideration for the issue thereof, provided that nothing in this Article shall impair the obligations, covenants and agreements of the Company contained in this Agreement and in any Notes, Pre-Paid Purchase Contracts and/or Warrants constituting a part of the Units.

Section 7.03. Compliance Certificates and Opinions. Except as otherwise expressly provided by this Agreement, upon any application or request by the Company to the Agent to take any action under any provision of this Agreement, the Company, as applicable, shall furnish to the Agent an Officer’s Certificate stating that all conditions precedent, if any, provided for in this Agreement relating to the proposed action have been complied with and an Opinion of Counsel stating that, in the opinion of such counsel, all such conditions precedent, if any, have been complied with, except that in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Agreement relating to such particular application or request, no additional certificate or opinion need be furnished.

Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Agreement shall include:

(i) a statement that each individual signing such certificate or opinion has read such covenant or condition and the definitions herein relating thereto;

(ii) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(iii) a statement that, in the opinion of each such individual, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and

(iv) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with.

Section 7.04. Form of Documents Delivered to Agent. In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or

covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate, statement or opinion of an officer or counsel of or for the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate, statement or opinion is based are erroneous. Any such certificate, statement or opinion may be based, insofar as it relates to factual matters, upon a certificate, statement or opinion of, or representations by, an officer or officers of the Company, as applicable, stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Agreement, they may, but need not, be consolidated and form one instrument.

Section 7.05. Maintenance of Office or Agency. So long as Units are authorized for issuance pursuant to this Agreement or are outstanding hereunder, the Company will maintain in the Borough of Manhattan, The City of New York, an office or agency where Units may be presented or surrendered for delivery, where Units may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of Units and this Agreement may be served. The Company hereby initially designates the Agent as its office or agency in the Borough of Manhattan, The City of New York, for each of said purposes. The Company will give prompt written notice to the Agent of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Agent with the name and address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Agent, and the Company hereby appoints the Agent as its agent to receive all such presentations, surrenders, notices and demands.

The Company may also from time to time designate one or more other offices or agencies where Units may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligations to maintain offices or agencies provided for in this Section. The Company will give prompt written notice to the Agent of any such designation or rescission and of any change in the location of any such other office or agency.

Section 7.06. Notices, Etc. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Agreement to be made upon, given or furnished to, or filed with,

(a) the Agent, by any Holder or by the Company shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, to the Agent at its Corporate Trust Office, Attention: Corporate Finance, or at any other address previously furnished in writing by the Agent to the Holders and the Company, or

(b) the Company by the Agent or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, addressed to the Company at 0000 Xxxxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Treasurer, or at any other address previously furnished in writing to the Agent by the Company.

Section 7.07. Notices to Holders; Waiver. The Company may cause notice to be given to the Holders by providing the Agent with a form of notice to be (a) in the case of Definitive Units, distributed by the Agent to the Holders by first class mail, or (b) in the case of Global Units, made available by the Depositary to its participants in accordance with the custom and practices of the Depositary.

Where this Agreement provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice.

Waivers of notice by Holders shall be filed with the Agent, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Section 7.08. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

Section 7.09. Successors and Assigns. All covenants and agreements in this Agreement, the Units and the Unit Certificates by the Company shall bind its successors and assigns, whether so expressed or not.

Section 7.10. Separability Clause. In case any provision in this Agreement or in the Units, Unit Certificates or Notes, Pre-Paid Contracts or Warrants shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions hereof and thereof shall not in any way be affected or impaired thereby.

Section 7.11. Benefits of Agreement. Nothing in this Agreement or in the Units, Unit Certificates, the Indenture, Pre-Paid Contracts or the Warrant Agreement, the Notes or the Warrants, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders of any Units, any benefits or any legal or equitable right, remedy or claim under this Agreement.

Section 7.12. Governing Law; Waiver of Trial by Jury. This Agreement, the Units, the Unit Certificate, the Notes, the Pre-Paid Contracts and the Warrants shall be governed and construed in accordance with the laws of the State of New York. The Company and the Agent irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Section 7.13. Counterparts. This Agreement may be executed in any number of counterparts by the parties hereto on separate counterparts, each of which, when so executed and delivered, shall be deemed an original, but all such counterparts shall together constitute one and the same instrument.

Section 7.14. Inspection of Agreement. A copy of this Agreement shall be available at all reasonable times during normal business hours at the Corporate Trust Office of the Agent for inspection by any Holder.

IN WITNESS WHEREOF, the Company, the Agent, the Trustee and the Warrant Agent have duly executed this Agreement as of the day and year first above set forth.
