SECTION 2.03 Execution and Authentication.

Two Officers shall sign the Securities for the Company by manual or facsimile signature. If an Officer whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall be valid nevertheless.

A Security shall not be valid until authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

The Trustee shall, upon a written order of the Company signed by one Officer of the Company, authenticate for original issue Securities in aggregate principal amount specified in such order.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so.

An authenticating agent has the same rights as an Agent to deal with the Company or an Affiliate of the Company.

The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “ Registrar ”) and an office or agency where Securities may be presented for payment (the “ Paying Agent ”). The Registrar shall keep a register of the Securities (the “ Register ”) and of their transfer and exchange. The Company may appoint one or more co-Registrars and one or more additional Paying Agents for the Securities. The term “Paying Agent” includes any additional paying agent and the term “Registrar” includes any additional registrar. The Company may change any Paying Agent or Registrar without prior notice to any Holder.

The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which shall incorporate the terms of the TIA and implement the terms of this Indenture that relate to such Agent. The Company shall give prompt written notice to the Trustee of the name and address of any Agent who is not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent or Registrar; provided, however, that none of the Company, its Subsidiaries or the Affiliates of the foregoing shall act (i) as Paying Agent in connection with redemptions, offers to purchase, discharges and defeasance, as otherwise specified in this Indenture, and (ii) as Paying Agent or Registrar if a Default or Event of Default has occurred and is continuing.

The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Global Securities.

The Company hereby initially appoints the Trustee as Registrar and Paying Agent for the Securities.

SECTION 2.05 Paying Agent to Hold Assets in Trust.

Not later than 11:00 a.m. (New York City time) on each due date of the principal and interest on any Securities, the Company shall deposit with one or more Paying Agents money in immediately available funds sufficient to pay such principal and interest so becoming due. The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all assets held by the Paying Agent for the payment of principal of and interest on the Securities (whether such money has been paid to it by the Company or any other obligor on the Securities) and shall notify the Trustee of any failure by the Company (or any other obligor on the Securities) in making any such payment. While any such failure continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary of the Company) shall have no further liability for the money so paid over to the Trustee.

If the Company or any Subsidiary of the Company or any Affiliate of any of them acts as Paying Agent, it shall, prior to or on each due date of any principal of or interest on the Securities, segregate and hold in a separate trust fund for the benefit of the Holders a sum of money sufficient with monies held by all other Paying Agents, to pay such principal or interest so becoming due until such sum of money shall be paid to such Holders or otherwise disposed of as provided in this Indenture, and will promptly notify the Trustee of its actions or failure to act.

SECTION 2.06 Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply with Section 312(a) of the TIA. If the Trustee is not the Registrar, the Company shall furnish to the Trustee prior to or on each interest payment date for the Securities and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders relating to such interest payment date or request, as the case may be.

SECTION 2.07 General Provisions Relating to Transfer and Exchange.

The Securities are issuable only in registered form. A Holder may transfer a Security only by written application to the Registrar or another transfer agent stating the name of the proposed transferee and otherwise complying with the terms of this Indenture. No such transfer shall be effected until, and such transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of the transfer by the Registrar in the Register. Prior to the registration of any transfer by a Holder as provided herein, the Company, the Trustee, and any agent of the Company shall treat the person in whose name the Security is registered as the owner thereof for all purposes whether or not the Security shall be overdue, and neither the Company, the Trustee, nor any such agent shall be affected by notice to the contrary. Furthermore, any Holder of a Global Security shall, by acceptance of such Global Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by the Holder of such Global Security (or its agent) and that ownership of a beneficial interest in the Security shall be required to be reflected in a book-entry.

When Securities are presented to the Registrar or another transfer agent with a request to register the transfer or to exchange them for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met (including that such Securities are duly endorsed or accompanied by a written instrument of transfer duly executed by the Holder thereof or by an attorney who is authorized in writing to act on behalf of the Holder). Subject to Section 2.03, to permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange or redemption of the Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or other similar governmental charge payable upon exchanges pursuant to Section 2.12, 3.06 or 9.05 hereof).

Neither the Registrar nor any other transfer agent nor the Company shall be required to:

(i) issue, register the transfer of or exchange any Security during a period beginning at the opening of business 15 Business Days before the day of any selection of Securities for redemption under Section 3.02 hereof and ending at the close of business on the day of selection; or

(ii) register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

Each Holder of a Security agrees to indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable United States Federal or state securities law.

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

SECTION 2.08 Book-Entry Provisions for Global Securities.

(a) The Global Securities initially shall:

(i) be registered in the name of the Depositary or the nominee of such Depositary; and

(ii) be delivered to the Trustee as custodian for such Depositary.

Members of, or participants in, the Depositary (“ DTC Participants ”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under such Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing contained herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and the DTC Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

(b) Transfers of a Global Security shall be limited to transfers of such Global Security in whole, but not in part, to the Depositary, its successors or their respective nominees. Beneficial owners may transfer their interests in Global Securities in accordance with the rules and procedures of the Depositary.

(c) Any beneficial interest in one of the Global Securities that is transferred to a person who takes delivery in the form of an interest in another Global Security will, upon transfer, cease to be an interest in such Global Security and become an interest in such other Global Security and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Security for as long as it remains such an interest.

(d) The registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including DTC Participants and Persons that may hold interests through DTC Participants, to take any action that a Holder is entitled to take under this Indenture or the Securities.

(e) If at any time:

(i) the Company notifies the Trustee in writing that the Depositary is no longer willing or able to continue to act as Depositary for the Global Securities or the Depositary ceases to be a “clearing agency” registered under the Exchange Act, and a successor depositary for the Global Securities is not appointed by the Company within 90 days of such notice or cessation;

(ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Securities in definitive form under this Indenture in exchange for all or any part of the Securities represented by a Global Security or Global Securities; or

(iii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depositary,

subject to this Section 2.08(e), the Depositary shall surrender such Global Security or Global Securities to the Trustee for cancellation and then the Company shall execute, and the Trustee shall authenticate and deliver in exchange for such Global Security or Global Securities, Physical Securities, as applicable, in an aggregate principal amount equal to the principal amount of such Global Security or Global Securities. Such Physical Securities shall be registered in such names as the Depositary shall identify in writing as the beneficial owners, or participant nominees, of the Securities represented by such Global Security or Securities (or any nominee thereof).

(f) Notwithstanding the foregoing, in connection with any transfer of a portion of the beneficial interests in a Global Security to beneficial owners pursuant to paragraph (e) of this Section 2.08, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of such Global Security in an amount equal to the principal amount of the beneficial interest in such Global Security to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Physical Securities of like tenor and amount.

SECTION 2.09 Replacement Securities.

If a mutilated Security is surrendered to the Trustee or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of the Trustee and the Company are met; provided that, if any such Security has been called for redemption in accordance with the terms thereof, the Trustee may pay the Redemption Price thereof on the Redemption Date without authenticating or replacing such Security. The Trustee or the Company may, in either case, require the Holder to provide an indemnity bond sufficient in the judgment of each of the Trustee and the Company to protect the Company, the Trustee or any Agent from any loss which any of them may suffer if a Security is replaced or if the Redemption Price therefor is paid pursuant to this Section 2.09. The Company may charge the Holder who has lost a Security for its expenses in replacing a Security.

Every replacement Security is an obligation of the Company and shall be entitled to the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

SECTION 2.10 Outstanding Securities.

The Securities outstanding at any time are all the Securities authenticated by the Trustee, except for (i) those cancelled by it, (ii) those delivered to it for cancellation and (iii) those described in this Section as not outstanding.

If a Security is replaced pursuant to Section 2.09 hereof, it ceases to be outstanding and interest ceases to accrue unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser.

If all principal of and interest on any Security are considered paid under Section 4.01 hereof, such Security ceases to be outstanding and interest on it ceases to accrue.

Except as provided in Section 2.11 hereof, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds such Security.

SECTION 2.11 Treasury Securities.

In determining whether the Holders of the required aggregate principal amount of Securities of any series have concurred in any direction, waiver or consent, Securities owned by the Company or an Affiliate of the Company shall be considered as though they are not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which such Trustee actually knows are so owned shall be so disregarded.

SECTION 2.12 Temporary Securities.

Until definitive Securities are ready for delivery, the Company may prepare and execute, and the Trustee shall authenticate upon a written order of the Company signed by one Officer of the Company, temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare, and the Trustee shall authenticate, definitive Securities in exchange for temporary Securities. Holders of temporary Securities shall be entitled to all of the benefits of this Indenture.

SECTION 2.13 Cancellation.

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange, payment or repurchase. The Trustee shall cancel all Securities surrendered for registration of transfer, exchange, payment, repurchase, redemption, replacement or cancellation and shall return such cancelled Securities to the Company upon the Company’s written request (subject to the record retention requirements of the Exchange Act). The Company may not issue new Securities to replace Securities that it has paid or that have been delivered to the Trustee for cancellation.

SECTION 2.14 CUSIP Numbers.

The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and the Trustee shall use CUSIP numbers in notices of redemption or exchange as a convenience to Holders; provided that any such notice shall state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any such notice 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 shall promptly notify the Trustee of any change in the CUSIP numbers.

SECTION 2.15 Defaulted Interest.

If the Company fails to make a payment of interest on Securities, it shall pay such defaulted interest plus (to the extent lawful) any interest payable on the defaulted interest, in any lawful manner. It may elect to pay such defaulted interest, plus any such interest payable on it, to the Persons who are Holders of such Securities on which the interest is due on a subsequent special record date. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each such Security. The Company shall fix any such record date and payment date for such payment. At least 15 days before any such record date, the Company shall mail to Holders affected thereby a notice that states the record date, interest payment date, and amount of such interest to be paid.

SECTION 2.16 Special Record Dates.

The Company may, but shall not be obligated to, set a record date for the purpose of determining the identity of Holders of Securities entitled to consent to any supplement, amendment or waiver permitted by this Indenture. If a record date is fixed, the Holders of Securities outstanding on such record date, and no other Holders, shall be entitled to consent to such supplement, amendment or waiver or revoke any consent previously given, whether or not such Holders remain Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless consents from Holders of the aggregate principal amount of Securities required hereunder for such amendment or waiver to be effective shall have also been given and not revoked within such 90-day period.

ARTICLE III

REDEMPTION

SECTION 3.01 Notices to Trustee.

If the Company elects to redeem any series of Securities pursuant to the optional redemption provisions set forth in the supplemental indenture relating to such series of Securities, it shall notify the Trustee in writing of the intended Redemption Date, the principal amount of Securities to be redeemed and the CUSIP numbers of the Securities to be redeemed. The Company shall give each notice to the Trustee provided for in this Section 3.01 at least days fifteen (15) days before the giving of the notice of redemption pursuant to Section 3.03 hereof (unless a shorter period is satisfactory to the Trustee).

SECTION 3.02 Selection of Securities to Be Redeemed.

If fewer than all the Securities of any series are to be redeemed, the Trustee shall select the Securities of such series to be redeemed from the outstanding Securities of such series by a method that complies with the requirements of any exchange on which the Securities are listed, or, if the Securities are not listed on an exchange, on a pro rata basis or by lot or in accordance with any other method the Trustee considers fair and appropriate. The Trustee will make the selection from outstanding Securities of that series not previously called for redemption.

Securities and portions thereof of any series that the Trustee selects shall be in amounts equal to the minimum authorized denomination for Securities to be redeemed or any integral multiple thereof. The Trustee may select for redemption portions of the principal amount of Securities that have denominations larger than the minimum denomination in which Securities of the applicable series may be issued. Provisions of this Indenture that apply to Securities of any series called for redemption also apply to portions of Securities of such series called for redemption. The Trustee shall notify the Company promptly in writing of the Securities or portions of Securities of any series to be called for redemption.

SECTION 3.03 Notice of Redemption.

At least 30 days but not more than 60 days before the Redemption Date, the Company shall mail a notice of redemption by first-class mail to each Holder whose Securities are to be redeemed in whole or in part at the address of such Holder appearing in the Register.

The notice shall identify the principal amount and series of each Security to be redeemed and shall state:

(a) the Redemption Date;

(b) the method being used to determine the Redemption Price;

(c) if fewer than all outstanding Securities are to be redeemed, the portion of the principal amount of the Securities to be redeemed and that, after the Redemption Date, upon surrender of such Security, a new Security in principal amount equal to the unredeemed portion will be issued;

(d) the name and address of the Paying Agent;

(e) that Securities called for redemption must be presented and surrendered to the Paying Agent to collect the Redemption Price plus accrued interest, if any;

(f) that, unless the Company defaults in payment of the Redemption Price, interest on Securities (or the portions thereof) called for redemption ceases to accrue interest on and after the Redemption Date, and, if applicable, those Securities (or the portion thereof called for redemption) will cease on the Redemption Date (or such other date as if provided in the supplemental indenture relating to the Securities) to be convertible into, or exchangeable for, other securities or assets;

(g) if applicable, the current conversion or exchange price; and

(h) the CUSIP numbers, if any, of the Securities to be redeemed.

At the Company’s written request, the Trustee shall give the notice of redemption in the Company’s name and at its expense.

SECTION 3.04 Effect of Notice of Redemption.

Once the notice of redemption is mailed, Securities called for redemption become irrevocably due and payable on the Redemption Date at the Redemption Price. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price, plus accrued and unpaid interest to the Redemption Date.

The notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Securities shall not affect the validity of the proceeding for the redemption of Securities of any other Holder.

SECTION 3.05 Deposit of Redemption Price.

Prior to 11:00 a.m., New York City time, on the Redemption Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or an Affiliate of the Company is acting as the paying Agent, shall segregate and hold in trust) an amount of money sufficient to pay the Redemption Price of all Securities to be redeemed on that date, together with accrued and unpaid interest to the Redemption Date, except for Securities or portions thereof called for redemption which have been delivered by the Company to the Trustee for cancellation or Securities which have been surrendered for conversion or exchange. If any Securities called for redemption are converted or exchanged, any money deposited with the Trustee or Paying Agent for redemption of those Securities shall be promptly paid to the Company upon its request, or, if the money is held in trust by the Company or a Subsidiary as Paying Agent, the money will be discharged from the trust.

SECTION 3.06 Securities Redeemed in Part.

Upon surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate for the Holder at the expense of the Company, a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

SECTION 3.07 Holder's Right to Require Redemption.

Holders of Securities of a series will have the right to require the Company to redeem those Securities only to the extent, and only on the terms, set forth in the supplemental indenture relating to the Securities of that series. If Holders of Securities of a series have the right to require the Company to redeem those Securities, unless otherwise provided in the supplemental indenture relating to the Securities of that series, the terms of the redemption will include those set forth in Section 3.08.

SECTION 3.08 Procedure for Requiring Redemption.

If a Holder has the right to require the Company to redeem Securities, to exercise that right, the Holder must deliver the Securities to the Paying Agent, endorsed for transfer and with the form on the reverse side regarding the option to require redemption completed. Delivery of Securities to the Paying Agent as provided in this Section 3.07 will constitute an irrevocable election to cause the specified principal amount of Securities to be redeemed. When Securities are delivered to the Paying Agent as provided in this Section, unless the Company fails to make the payments due as a result of the redemption within twenty (20) days after the Securities are delivered to the Paying Agent, interest on the Securities will cease to accrue and, if the Securities are convertible or exchangeable, the Holder's right to convert or exchange the Securities will terminate.

The Company's determination of all questions regarding the validity, eligibility (including time of receipt) and acceptance of any Security for redemption will be final and binding.

ARTICLE IV

COVENANTS

SECTION 4.01 Payment of Securities.

The Company shall pay, or cause to be paid, the principal of and interest on the Securities on the dates and in the manner provided in the Securities and the supplemental Indenture relating to the series. Principal and interest shall be considered paid on the date due if the Paying Agent, if other than the Company, a Subsidiary of the Company or any Affiliate of any of them, holds as of 11:00 a.m. (New York City time) on that date immediately available funds designated for and sufficient to pay all principal and interest then due. If the Company or any Subsidiary of the Company or any Affiliate of any of them acts as Paying Agent, principal or interest shall be considered paid on the due date if the entity acting as Paying Agent complies with the second paragraph of Section 2.05 hereof.

The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Company hereby designates the New York office of the Trustee located at ___________________________, as one such office or agency of the Company in accordance with Section 2.04 hereof.

The Company shall also comply with the other provisions of Section 314(a) of the TIA.

(b) Delivery of reports, information and documents to the Trustee pursuant to this Section 4.03 is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

SECTION 4.04 Compliance Certificate.

The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, an Officers’ Certificate, one of the signers of which is the chief executive officer, vice chairman, the chief financial officer, executive vice president or the chief accounting officer of the Company, stating that in the course of the performance by the signers of their duties as officers of the Company, they would normally have knowledge of any failure by the Company to comply with all conditions, or Default by the Company with respect to any covenants, under this Indenture, and further stating whether or not they have knowledge of any such failure or Default and, if so, specifying each such failure or Default, the nature and status thereof and what action the Company is taking or proposes to take with respect thereto.

ARTICLE V

MERGER, ETC.

SECTION 5.01 When Company May Merge, etc.

The Company shall not consolidate or merge with or into, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its assets to, any Person unless :

ARTICLE VI

DEFAULTS AND REMEDIES

SECTION 6.01 Events of Default.

An “Event of Default” with respect to each series of the Securities occurs when any of the following occurs:

(a) the Company defaults in the payment of the principal, premium, or sinking fund payment, if any, of any Security of such series when it becomes due and payable at maturity, upon acceleration, repurchase, redemption or otherwise, unless the time for payment is extended;

(b) the Company defaults in the payment of interest on any Security of such series when it becomes due and payable and such Default continues for a period of ninety (90) days, unless the time for payment is extended;

(c) the Company fails to comply in any material respect with any of its other agreements or covenants in, or provisions of, the Securities or this Indenture and the Company and such Default continues for a period of ninety (90) days after the Company receives written notice of such Default from the Trustee, or the Company the Trustee receive written notice of such Default from the Holders of at least 51% in aggregate principal amount of the outstanding Securities of such series;

(d) the Company or a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(i) commences a voluntary case or proceeding;

(ii) consents to the entry of an order for relief against it in an involuntary case or proceeding;

(iii) consents to the appointment of a Custodian of it or for any substantial part of its property; or

(iv) makes a general assignment for the benefit of its creditors; or

(e) a court of competent jurisdiction enters an order or decree under any applicable Bankruptcy Law that:

(i) is for relief against the Company or any Significant Subsidiary in an involuntary case or proceeding against the Company or any Significant Subsidiary;

(ii) appoints a Custodian for the Company or any Significant Subsidiary or for any substantial part of its property; or

(iii) orders the winding up or liquidation of the Company or any Significant Subsidiary,

and any such order or decree under this clause (3) remains unstayed and in effect for ninety (90) days.

Any notice of default under clause (iii) of this Section 6.01 must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.”

Each of the occurrences described in clauses (i) through (v) of this Section 6.01 will constitute an Event of Default whatever the reason for the occurrence and whether it is voluntary or involuntary or is 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 under clause (i), (ii) or (iii) of this Section 6.01 with regard to Securities of a particular series will not constitute a Default with regard to Securities of any other series except to the extent, if any, provided in the supplemental indenture relating to the other series.

SECTION 6.02 Acceleration.

Subject to Article XII, if an Event of Default with respect to any series of outstanding Securities (other than an Event of Default specified in clause (iv) or (v) of Section 6.01 hereof) occurs and is continuing, the Trustee or the Holders of at least 51% in aggregate principal amount of the outstanding Securities of the applicable series, by written notice to the Company, and to the Trustee if notice is given by such Holders, may declare due and payable the unpaid principal amount of all Securities of such series plus any unpaid premium or accrued and unpaid interest, if any, to the date of payment. Upon a declaration of acceleration, such principal, premium and accrued and unpaid interest to the date of payment shall be due and payable.

If an Event of Default specified in clause (iv) or (v) of Section 6.01 hereof occurs, all unpaid principal, premium and accrued interest on the Securities shall become and be immediately due and payable without any notice, declaration or other action on the part of the Trustee or any Holder.

The Holders of a majority in aggregate principal amount of any outstanding series of Securities by written notice to the Trustee may rescind and annul an acceleration and its consequences if (i) all existing Events of Default, other than the nonpayment of principal, premium or interest on the Securities which have become due solely because of the acceleration, have been cured or waived and (ii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. Such rescission or annulment will not extend to any subsequent or other Default or impair any consequent right.

SECTION 6.03 Other Remedies.

If an Event of Default with respect to any series of outstanding Securities occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of or interest on such series of Securities or to enforce the performance of any provision of such series of Securities or this Indenture.

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

SECTION 6.04 Waiver of Past Defaults.

Subject to Sections 6.07 and 9.02 hereof, the Holders of at least a majority in aggregate principal amount of any series of outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default except a Default or Event of Default in the payment of the principal of or interest on such series of Securities ( provided, however, that, subject to Section 6.07, the Holders of a majority in aggregate principal amount of the then outstanding Securities may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). When a Default or Event of Default is waived, it is deemed cured and ceases, but no waiver will extend to any subsequent or other Default or impair any consequent right.

SECTION 6.05 Control by Majority.

The Holders of at least a majority in aggregate principal amount of any outstanding series of Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that (i) conflicts with law or this Indenture, (ii) the Trustee determines may be unduly prejudicial to the rights of other Holders of Securities of such series or (iii) may involve the Trustee in personal liability. The Trustee may take any other action that it deems proper which is not inconsistent with any such direction.

SECTION 6.06 Limitation on Suits.

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

(d) the Trustee does not comply with the request within sixty (60) days after receipt of the request and the offer of indemnity; and

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

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

SECTION 6.07 Rights of Holders To Receive Payment and to Demand Conversion.

Notwithstanding any other provision of this Indenture, subject to the provisions of Article XII, the right of any Holder of a Security to receive payment of principal of, premium, if any, or interest, if any, on the Security (and interest on overdue principal and interest on overdue installments of interest, if any, as provided in Section 4.01) on or after the respective due dates expressed or provided for in the Security, or in the case of redemption, on or after the Redemption Date, or in the case of conversion or exchange, to receive the security issuable upon conversion or exchange, or to bring suit for the enforcement of any such payment, conversion or exchange on or after such respective dates, shall not be impaired or affected without the consent of the Holder.

SECTION 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(i) or (ii) hereof occurs and is continuing with respect to the Securities, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company (and any other obligor on the Securities) for the whole amount of principal, premium, if any, and accrued interest, if any, remaining unpaid on the outstanding Securities, together with (to the extent lawful) interest on overdue principal and interest, and such further amount as shall be sufficient to cover the costs and, to the extent lawful, expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 7.08 hereof.

SECTION 6.09 Trustee May File Proofs of Claim.

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceeding relative to the Company (or any other obligor upon the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any custodian in any such judicial proceedings is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.08 hereof. Nothing contained in this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10 Priorities.

If the Trustee collects any amount of money with respect to the Securities pursuant to this Article VI, subject to Article XI, it shall pay out the money in the following order:

(First) to the Trustee, its agents and attorneys for amounts due under Section 7.08 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made by the Trustee and the costs and expenses of collection;

(Second) to Holders of Senior Indebtedness in accordance with Article XII hereof;

(Third) to Holders for amounts due and unpaid on the Securities for principal and interest, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and

The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. The Trustee shall notify the Company in writing reasonably in advance of any such record date and payment date.

SECTION 6.11 Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.06 hereof, a suit by Holders of more than 10% in aggregate principal amount of any outstanding series of Securities, or to any suit instituted by any Holder for the enforcement of the payment of the principal of, premium, if any, or interest on any Security held by that Holder on or after the due date provided in the Security or to any suit for the enforcement of the right to convert or exchange any Security in accordance with the provisions of a supplemental indenture applicable to that Security.

SECTION 6.12 Stay, Extension and Usury Laws.

The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim and will resist any and all efforts to be compelled to take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the principal of, premium, if any, and/or interest on any of the Securities as contemplated in this Indenture or a supplemental indenture, or which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

SECTION 6.13 Restoration of Positions.

If a judicial proceeding by the Trustee or a Holder to enforce any right or remedy under this Indenture or any supplemental indenture has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, except as otherwise provided in the judicial proceeding, the Company, the Trustee and the Holders will be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 6.14 Liability of Stockholders, Officers, Directors and Incorporators.

No stockholder, officer, director or incorporator, as such, past, present or future, of the Company, or any of its successor corporations, will have any personal liability in respect of the Company's obligations under this Indenture or any Securities by reason of his or its status as such stockholder, officer, director or incorporator; provided, however, that nothing in this Indenture or in the Securities will prevent recourse to and enforcement of the liability of any holder or subscriber to common stock of the Company which has not been fully paid up.

ARTICLE VII

TRUSTEE

SECTION 7.01 Duties of Trustee.

(a) If an Event of Default with respect to the Securities has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this 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 such person’s own affairs.

(iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof.

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to this Section 7.01 and to the provisions of the TIA.

(e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any financial liability in the performance of any of its duties under this Indenture or in the exercise of any of its right or power. The Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity satisfactory to it against any loss, liability, cost or expense (including, without limitation, reasonable fees of counsel).

(f) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(g) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder.

SECTION 7.02 Rights of Trustee.

Subject to Section 315(a) through (d) of the TIA:

(a) The Trustee may conclusively rely on any 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.

(f) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company.

(g) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

(h) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

(i) In no event shall the Trustee be responsible or liable for special or indirect loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(j) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture.

SECTION 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as such term is defined in Section 3.10(b) of the TIA), it must eliminate such conflict within ninety (90) days, apply to the SEC for permission to continue as trustee (to the extent permitted under Section 310(b) of the TIA) or resign. Any agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

SECTION 7.04 Money Held in Trust.

Money or U.S. Government Obligations held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company.

SECTION 7.05 Trustee’s Disclaimer.

The Trustee (i) is not responsible for and makes no representation as to the validity or adequacy of this Indenture, any supplemental indenture or the Securities, (ii) will not be accountable for the Company’s use of the proceeds from the Securities, (iii) will not be responsible for any statement in the Securities, this Indenture or any supplemental indenture, other than its certificate of authentication, and (iv) will not be responsible for any statement in any prospectus used in the sales of the Securities, other than statements, if any, provided in writing by the Trustee for use in such a prospectus.

SECTION 7.06 Notice of Defaults.

If a Default or Event of Default with respect to the Securities occurs and is continuing, and if it is actually known to the Trustee, the Trustee shall mail to Holders a notice of the Default or Event of Default within ninety (90) days after the occurrence thereof. Except in the case of a Default or Event of Default in payment of any such Security, the Trustee may withhold the notice if and so long as it in good faith determines that withholding the notice is in the interests of the Holders.

SECTION 7.07 Reports by Trustee to Holders.

The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required by Section 313 of the TIA at the times and in the manner provided by the TIA, which initially shall be not less than every twelve (12) months, which report may be dated as of a date up to 75 days prior to such transmission.

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

SECTION 7.08 Compensation and Indemnity.

The Company shall pay to the Trustee from time to time such compensation as shall be agreed in writing between the Company and the Trustee for its services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable disbursements, advances and expenses incurred by it, including in particular, but without limitation, those incurred in connection with the enforcement of any remedies hereunder. Such expenses may include the reasonable fees and out-of-pocket expenses of the Trustee’s agents and counsel.

Except as set forth in the next paragraph, the Company shall indemnify and hold harmless the Trustee and any predecessor trustee against any and all loss, liability, damage, claim or expense, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it arising out of or in connection with the acceptance or administration of the trust under this Indenture. The Trustee shall notify the Company promptly of any claim of which it has received written notice for which it may seek indemnity. The Company shall defend such claim and the Trustee shall cooperate in such defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and out-of-pocket expenses of such counsel.

The Company need not pay for any settlement made without its consent. The Company need not reimburse any expense or indemnify against any loss, liability, cost or expense incurred by the Trustee through its own negligence, willful misconduct or bad faith.

To secure the Company’s payment obligations in this Section 7.08, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay the principal of and interest on particular Securities. The Trustee’s right to receive payment of any amounts due under this Section 7.08 will not be subordinate to any other liability or indebtedness of the Company.

The Company’s payment obligations pursuant to this Section 7.08 shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in clause (iv) or (v) of Section 6.01 hereof occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law.

For the purpose of this Section 7.08, “Trustee” will include any predecessor Trustee, but the negligence, willful misconduct or bad faith of any Trustee will not affect the rights of any other Trustee under this Section 7.08, except for a successor Trustee pursuant to Section 7.10 .

SECTION 7.09 Replacement of Trustee.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.09.

The Trustee may resign and be discharged from the trust hereby created with respect to the Securities by so notifying the Company in writing. The Holders of a majority in aggregate principal amount of the then outstanding Securities may remove the Trustee by so notifying the Trustee and the Company in writing. The Company must remove the Trustee if:

(a) the Trustee fails to comply with Section 7.10 hereof or Section 310 of the TIA;

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(d) the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason, the Company shall promptly appoint a successor Trustee for the Securities. The Trustee shall be entitled to payment of its fees and reimbursement of its expenses while acting as Trustee. Within one (1) year after the successor Trustee takes office, the Holders of at least a majority in aggregate principal amount of then outstanding Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

Any Holder of Securities may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee if the Trustee fails to comply with Section 7.10 hereof.

If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within thirty (30) days after the giving of such notice of resignation or removal, the resigning or removed Trustee, as the case may be, may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The Company shall mail a notice of the successor Trustee’s succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.08 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.09, the Company’s obligations under Section 7.08 hereof shall continue for the benefit of the retiring Trustee with respect to expenses, losses and liabilities incurred by it prior to such replacement.

SECTION 7.10 Successor Trustee by Merger, Etc.

Subject to Section 7.09 hereof, 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 successor entity without any further act shall be the successor Trustee.

If at the time a successor by merger, conversion or consolidation to the Trustee succeeds to the trusts created by this Indenture any of the Securities have been authenticated but not delivered, the successor to the Trustee may adopt the certificate of authentication of the predecessor Trustee, and deliver the Securities which were authenticated by the predecessor Trustee; and if at that time any of the Securities have not been authenticated, the successor to the Trustee may authenticate those Securities either in the name of the predecessor or in its own name as the successor to the Trustee; and in either case the certificates of authentication will have the full force provided in this Indenture for certificates of authentication.

SECTION 7.11 Eligibility; Disqualification.

The Trustee shall at all times satisfy the requirements of Section 310(a)(1), (2) and (5) of the TIA. The Trustee shall at all times have a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition, which will be deemed for this paragraph to be its combined capital and surplus. The Trustee is subject to Section 310(b) of the TIA, including the optional provision permitted by the second sentence of Section 310(b)(9) of the TIA.

SECTION 7.12 Preferential Collection of Claims Against the Company.

The Trustee is subject to Section 311(a) of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated therein.

(c) The Trustee shall deliver or pay to the Company from time to time upon the request of the Company any U.S. Government Obligations or money held by it as provided in Sections 8.01, 8.03 or 8.04 hereof which, in the opinion of a nationally recognized firm of independent certified public accountants expressed in a written certification thereof delivered to the Trustee, are then in excess of the amount thereof which then would have been required to be deposited for the purpose for which such U.S. Government Obligations or money were deposited or received. This provision shall not authorize the sale by the Trustee of any U.S. Government Obligations held under this Indenture.

SECTION 9.02 With Consent of Holders.

Except as provided below in this Section 9.02, this Indenture, the Securities may be amended or supplemented, and noncompliance in any particular instance with any provision of this Indenture or the Securities may be waived, in each case with the written consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Securities affected thereby; provided, however , that any amendment to or supplement of this Indenture or the Securities that by its terms affects the rights of Holders of any series of then outstanding Securities but not the others series may be effected, and any default or compliance with any provision of this Indenture affecting the Holders of any series of then outstanding Securities but not the other series may be waived, with the consent of at least a majority in aggregate principal amount of the Securities of the affected series.

Without the consent of each Holder of Securities that is affected thereby, an amendment or waiver under this Section 9.02 may not:

(a) reduce the aggregate principal amount of Securities of any series the Holders of which must consent to an amendment, supplement modification or waiver of any provision of this Indenture;

After an amendment or waiver under this Section 9.02 becomes effective, the Company shall mail to Holders affected thereby a notice briefly describing the amendment or waiver.

Every amendment to this Indenture or the Securities shall be set forth in a supplemental indenture that complies with the TIA as then in effect.

SECTION 9.04 Revocation and Effect of Consents.

Until an amendment, supplement modification or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security; provided, however, that unless a record date shall have been established pursuant to Section 2.16 hereof, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives written notice of revocation before the date the amendment, supplement, modification or waiver becomes effective. An amendment, supplement modification or waiver becomes effective on receipt by the Trustee of consents from the Holders of the requisite percentage principal amount of the outstanding Securities, and thereafter shall bind every Holder of Securities; provided, however, if the amendment, supplement modification or waiver makes a change described in any of the clauses (i) through (viii) of Section 9.02 hereof, the amendment, supplement, modification or waiver shall bind only each Holder of a Security which has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same indebtedness as the consenting Holder’s Security.

SECTION 9.05 Notation on or Exchange of Securities.

If an amendment, supplement, modification or waiver changes the terms of a Security:

(a) the Trustee may require the Holder of a Security to deliver such Security to the Trustee, the Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder and the Trustee may place an appropriate notation on any Security thereafter authenticated; or

(b) if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.06 Trustee to Sign Amendment, etc.

The Trustee shall sign any amendment authorized pursuant to this Article IX if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it.

Before any payment may be made by the Company of the principal of or interest on the Securities pursuant to the provisions of the previous sentence, and upon any such dissolution or winding up or liquidation or reorganization, any payment or distribution of assets or securities of the Company of any kind or character, whether in cash, property or securities, to which the Holders or the Trustee on their behalf would be entitled, except for the provisions of this Article XII, shall be made by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, directly to the holders of the Senior Indebtedness or their representatives to the extent necessary to pay all such Senior Indebtedness in full after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness.

Nothing contained in this Article XII shall limit the right of the Trustee or the Holders of Securities to take any action to accelerate the maturity of the Securities pursuant to Section 6.02 or to pursue any rights or remedies hereunder; provided that all Obligations with respect to Senior Indebtedness then or thereafter due or declared to be due shall first be paid in full before the Holders or the Trustee are entitled to receive any payment from the Company of principal of or interest on the Securities.

SECTION 12.03 Payments May Be Paid Prior to Dissolution.

Nothing contained in this Article XII or elsewhere in this Indenture shall prevent the Company, except under the conditions described in Section 12.02, from making payments at any time for the purpose of making such payments of principal of and interest on the Securities, or from depositing with the Trustee any moneys for such payments. The Company shall give prompt written notice to the Trustee of any dissolution, winding up, liquidation or reorganization of the Company.

SECTION 12.04 Rights of Holders of Senior Indebtedness Not to Be Impaired.

No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act in good faith by any such holder, or by any noncompliance by the Company, with the terms and provisions and covenants herein regardless of any knowledge thereof any such holder may have or otherwise be charged with.

SECTION 12.05 Authorization to Trustee to Take Action to Effectuate Subordination.

For purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the Holders would be entitled except for the provisions of this Article XII, and no payment over pursuant to the provisions of this Article XII to the holders of Senior Indebtedness by the Holders, shall, as among the Company, its creditors other than the holders of Senior Indebtedness and the Holders, be deemed to be a payment or distribution by the Company to or on account of Senior Indebtedness.

The provisions of this Article XII are and are intended solely for the purpose of defining the relative rights of the Holders, on the one hand, and the holders of Senior Indebtedness, on the other hand.

If any payment or distribution to which the Holders would otherwise have been entitled but for the provisions of this Article XII shall have been applied, pursuant to the provisions of this Article XII, to the payment of all amounts payable under Senior Indebtedness, then and in such case, the Holders shall be entitled to receive from the holders of such Senior Indebtedness at the time outstanding any payments or distributions received by such holders of Senior Indebtedness in excess of the amount sufficient to pay all Obligations in respect of Senior Indebtedness in full.

SECTION 12.07 Obligations of Company Unconditional.

Nothing contained in this Article XII or elsewhere in this Indenture or in any Security is intended to or shall impair, as between the Company and the Holders, the obligations of the Company, which are absolute and unconditional, to pay to the Holders the principal of, premium, if any, and interest on the Securities as and when the same shall become due and payable in accordance with their terms or is intended to nor shall affect the relative rights of the Holders and creditors of the Company other than the holders of Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or any Holder from exercising all remedies otherwise permitted by applicable law upon Default under this Indenture, subject to the rights, if any, under this Article XII of the holders of such Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy.

The failure to make a payment on account of principal of, premium, if any, or interest on the Securities by reason of any provision of this Article XII shall not be construed as preventing the occurrence of an Event of Default under Section 6.01.

SECTION 12.08 Trustee Entitled to Assume Payments Not Prohibited in Absence of Notice.

The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment to or by the Trustee in respect of the Securities.

Unless at least two (2) Business Days prior to the date on which by the terms of this Indenture any moneys are to be deposited by the Company with the Trustee or any Paying Agent (whether or not in trust) for any purpose (including, without limitation, the payment of the principal of or the interest on any Security), the Trustee or Paying Agent shall have received with respect to such moneys the notice provided for in the preceding sentence, the Trustee or Paying Agent shall have full power and authority to receive such moneys and to apply the same to the purpose for which they were received and shall not be affected by any notice to the contrary which may be received by it on or after such date. Nothing contained in this Section 12.09 or Section 12.03 shall limit the right of the holders of Senior Indebtedness to recover payments as contemplated by Section 12.02. The Trustee shall be entitled to rely on the delivery to it of a written notice by a person representing himself or itself to be a holder of such Senior Indebtedness (or a trustee on behalf of, or representative of, such holder) to establish that such notice has been given by a holder of such Senior Indebtedness or a trustee or representative on behalf of any such holder. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article XII, the Trustee may request such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such person, the extent to which such person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such person under this Article XII, and if such evidence is not furnished, the Trustee may defer any payment which it may be required to make for the benefit of such person pursuant to the terms of this Indenture pending judicial determination as to the rights of such person to receive such payment.

The Trustee shall not be deemed to owe any duty to the holders of Senior Indebtedness and shall not be liable to any such holders if the Trustee shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article XII or otherwise. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article XII and no implied covenants or obligations with respect to holders of Senior Indebtedness shall be read into this Indenture against the Trustee.
