If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided further that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date.

which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.6.

If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.6.

          With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.

          Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

          In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

          SECTION 1.13. Legal Holidays.

          In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a

               (21) any addition to or change in the covenants set forth in Article X which applies to Securities of the series; and

          All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 3.3) set forth, or determined in the manner provided, in the Officers’ Certificate referred to above or in any such indenture supplemental hereto. All Securities of any one series need not be issued at the same time and, unless otherwise provided, a series may be reopened for issuances of additional Securities of such series.

          If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of the series.

          SECTION 3.2. Denominations.

          The Securities of each series shall be issuable only in registered form without coupons and only in such denominations as shall be specified as contemplated by Section 3.1. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series shall be issuable in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

          SECTION 3.3. Execution, Authentication, Delivery and Dating.

          The Securities shall be executed on behalf of the Company by the Chairman of its Board of Directors, its principal financial officer, its Chief Executive Officer, its President or one of its Vice Presidents, its Treasurer or its Assistant Treasurer, attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile.

          The Guarantee endorsed on any Securities shall be executed on behalf of the Guarantor by the Chairman of its Board of Directors, its principal financial officer, its Chief Executive Officer, its President or one of its Vice Presidents, its Treasurer or its Assistant Treasurer, attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Guarantee may be manual or facsimile.

          Securities or any Guarantee endorsed thereon bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company or the Guarantors, as applicable, shall bind the Company or the Guarantors, as

applicable, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

          At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company and, if applicable, having endorsed thereon the Guarantees executed as provided in Section 13.1 to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order (which may provide that Securities that are the subject thereof will be authenticated and delivered by the Trustee from time to time upon the telephonic or written order of Persons designated in said Company Order and that such Persons are authorized to determine such terms and conditions of said Securities as are specified in the Company Order) shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Section 3.1, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall receive, and (subject to Section 6.1) shall be fully protected in conclusively relying upon, a copy of such Board Resolution, the Officers’ Certificate setting forth the terms of the series and an Opinion of Counsel, with such Opinion of Counsel stating:

               (1) that such terms have been established in conformity with the provisions of this Indenture; and

               (2) that this Indenture and such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, and, if applicable, the Guarantees endorsed thereon will constitute valid and legally binding obligations of the Guarantors, in each case enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

          However, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

          Notwithstanding the provisions of Section 3.1 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.1 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.

          Each Security shall be dated the date of its authentication.

          No Security or Guarantee endorsed thereon shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for in Exhibit 1 executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.9, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

          SECTION 3.4. Temporary Securities.

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

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

          SECTION 3.5. Registration; Registration of Transfer and Exchange.

          The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office or in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers and exchanges of Securities. The Trustee initially is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers and exchanges of

Securities as herein provided. The Company may change any Security Registrar without prior notice to any Holder. The Company or any of its Subsidiaries may act as Security Registrar.

          The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer. Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company, if the requirements of this Indenture are met, shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, and having endorsed thereon a Guarantee executed by the Guarantors.

          If the requirements of this Indenture are met, then, at the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive, and having endorsed thereon a Guarantee executed by the Guarantor.

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

          No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment 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 Securities, other than exchanges pursuant to Sections 3.4, 9.6 or 11.7 not involving any transfer.

          If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected or identified for redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Security so selected or identified for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

          SECTION 3.6. Mutilated, Destroyed, Lost and Stolen Securities.

          If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, and having endorsed thereon a Guarantee executed by the Guarantors, if applicable.

          If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, and having endorsed thereon a Guarantee executed by the Guarantors, if applicable.

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

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

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

          SECTION 3.7. Payment of Interest; Interest Rights Preserved.

          Except as otherwise provided in or as contemplated by Section 3.1 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest; provided that on the maturity date for any series of Securities, the Company will pay accrued and unpaid

interest to the Person to whom the Company pays the principal amount, instead of the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date.

          In the case of Securities represented by a Global Security registered in the name of or held by a Depository or its nominee, unless otherwise specified by Section 3.1, payment of principal, premium, if any, and interest, if any, will be made to the Depository or its nominee, as the case may be, as the registered owner or Holder of such Global Security. None of the Company, the Guarantors, the Trustee, the Paying Agent, any Authenticating Agent or the Security Registrant for such Securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of a beneficial ownership interest in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

          Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

               (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not fewer than 10 days prior to the date of the proposed payment and not fewer than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 1.6, not fewer than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

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

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

          SECTION 3.8. Persons Deemed Owners.

          Prior to due presentment of a Security for registration of transfer, the Company, the Guarantors, the Trustee and any agent of the Company, the Guarantors or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 3.7) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and none of the Company, the Guarantors, the Trustee or any agent of the Company, the Guarantors or the Trustee shall be affected by notice to the contrary.

          In the case of a Global Security, so long as the Depository for such Global Security, or its nominee, is the registered owner of such Global Security, such Depository or such nominee, as the case may be, will be considered the sole owner or Holder of the Securities represented by such Global Security for all purposes under this Indenture. Except as provided in Section 3.1, owners of beneficial interests in a Global Security will not be entitled to have Securities that are represented by such Global Security registered in their names, will not receive or be entitled to receive physical delivery of such Securities in definitive form and will not be considered the owners or Holders thereof under this Indenture.

          Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall (i) prevent the Company, the Guarantors, the Trustee or any agent of the Company, the Guarantors or the Trustee from giving effect to any written certification, proxy or other authorization furnished by a Depository or (ii) impair, as between a Depository and holders of beneficial interests in any Global Security, the operation of customary practices governing the exercise of the rights of the Depository as Holder of such Global Security.

          None of the Company, the Guarantors, the Trustee, any Paying Agent, any Authenticating Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial

ownership interest in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest.

          SECTION 3.9. Cancellation.

          All Securities surrendered for payment, redemption or registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities shall be disposed of by the Trustee in accordance with its customary procedures.

          SECTION 3.10. Computation of Interest.

          Except as otherwise specified in or as contemplated by Section 3.1 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

          SECTION 3.11. CUSIP Numbers, ISINs and Common Code Numbers.

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

ARTICLE IV

Satisfaction and Discharge

          SECTION 4.1. Satisfaction and Discharge of Indenture.

          (1) This Indenture shall cease to be of further effect with respect to any series of Securities (except as to any surviving rights expressly provided for herein or in a supplemental indenture or Officers’ Certificate delivered pursuant to Section 3.1 for a

series of Securities), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture when:

     (i) the Company delivers to the Trustee all Outstanding Securities of a series (other than (x) Securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 3.6 and (y) Securities of such series for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 10.3) for cancellation or

     (ii) all Outstanding Securities of a series not theretofore delivered to the Trustee for cancellation:

               (3) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness

(or the payment of which is guaranteed by any Restricted Subsidiary), if that default is caused by a failure to pay principal at its stated maturity after giving effect to any applicable grace period, or results in the acceleration of such Indebtedness prior to its stated maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other Indebtedness under which there has been a payment default after stated maturity or the maturity of which has been so accelerated, aggregates $100 million or more; or

          SECTION 5.2. Acceleration of Maturity; Rescission and Annulment.

               (1) If an Event of Default, other than an Event of Default specified in Sections 5.1(5) or 5.1(6), with respect to Securities of any series at the time Outstanding occurs and is continuing, then either the Trustee or the Holders of at least 25% in principal amount of the Outstanding Securities of that series may require the Company to repay immediately the principal of and any unpaid premium and interest on (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof), all Outstanding Securities of the affected series. The Holders of at least a majority in principal amount of the Outstanding Securities of the affected series may rescind and annul that acceleration if all Events of Default with respect to the Securities of that series, other than the nonpayment of accelerated principal, have been cured or waived as provided in this Indenture. An Event of Default arising pursuant to Sections 5.1(5) or 5.1(6) shall cause the principal of, and any unpaid premium and interest on (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof), all Securities to become immediately due and payable without any declaration or other act by the Trustee, the Holders of the Securities or any other party.

               (2) Other than its duties in the case of a default, the Trustee is not obligated to exercise any of its rights or powers under this Indenture at the request or direction of any Holder of any series of Securities, unless the Holders offer to the Trustee indemnity reasonably satisfactory to the Trustee. If the Holders offer such indemnity to the Trustee, then the Holders of at least a majority in principal amount of the Outstanding Securities of the affected series will have the right, subject to certain limitations, to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities of that series.

          SECTION 5.3. Collection of Indebtedness and Suits for Enforcement by Trustee.

          The Company covenants that if:

               (1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days; or

               (2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof;

          the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates borne by such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

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

          If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

          SECTION 5.4. Trustee May File Proofs of Claim.

          In any case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other any judicial proceeding relative to the Company (or any Guarantor or other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and to pay to the Trustee any amount due it for the

reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.7.

          No provision of 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 5.5. Trustee May Enforce Claims Without Possession of Securities.

          All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

          SECTION 5.6. Application of Money Collected.

          Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or interest, upon presentation of the Securities in respect of which moneys have been collected and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 6.7;

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

     THIRD: In case the principal or any premium of the Securities of such series in respect of which moneys have been collected shall have become and shall be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such series for principal, any premium and interest, if any, with interest upon the overdue principal, and (to the extent that such interest has been collected by such Trustee and to the extent permitted by

law) upon overdue installments of interest at the rate borne by the Securities of such series; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities of such series, then to the payment of such principal, any premium and interest, without preference or priority of principal over interest, or of interest over principal, or of any installment of interest over any other installment of interest, or of any Security of such series over any other Security of such series, ratably to the aggregate of such principal and accrued and unpaid interest; and

          FOURTH: The balance, if any, to the Company or any other Person or Persons lawfully entitled thereto.

          SECTION 5.7. Limitation on Suits.

          No Holder of any Security of any series shall have any right to institute any proceeding under this Indenture, or for the appointment of a receiver or trustee, or for any other remedy under this Indenture, unless each of the following shall have occurred:

               (1) such Holder has previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of that series; and

               (2) the Holders of at least 25% in principal amount of the Outstanding Securities of that series have made a written request to the Trustee to pursue the remedy and have offered, and if requested provided, indemnity reasonably satisfactory to the Trustee against any loss, liability or expense incurred in connection with such pursuit; and

               (3) the Trustee has failed to comply with such request within 60 days after receipt of such notice, request and offer of indemnity; and

               (4) the Trustee has not received from the Holders of a majority in aggregate principal amount of Outstanding Securities of such series, a direction inconsistent with such request during that 60-day period.

          SECTION 5.8. Unconditional Right of Holders to Receive Principal, Premium and Interest.

          Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 3.7) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

          SECTION 5.9. Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding 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, subject to any determination in such proceeding, the Company, any Guarantor, the Trustee and the Holders shall 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 5.10. Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

          SECTION 5.11. Delay or Omission Not Waiver.

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

          SECTION 5.12. Control by Holders.

          The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series; provided that:

               (1) such direction shall not be in conflict with any rule of law or with this Indenture and the Trustee shall not have determined that the action so directed would be unjustly prejudicial to Holders of Securities of that series, or any other series, not taking part in such direction; and

               (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction or this Indenture.

          SECTION 5.13. Waiver of Past Defaults.

          The Holders of at least a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all of the Securities of such series waive any past default hereunder with respect to such series and its consequences, except a default:

          (1) in the payment of the principal of or any premium or interest on any Security of such series or the payment of any redemption price, purchase price or repurchase price with respect to any Securities of such series; or

          (2) in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of each Holder of such series affected.

          Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

          SECTION 5.14. Undertaking for Costs.

          All parties to this Indenture agree, and each Holder of any Security by his or her acceptance thereof, shall be deemed to have agreed that any court may in its discretion require, 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, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorney’s fees and expenses, against any party litigant in such suit, in the manner and to the extent provided in the Trust Indenture Act;  provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or in any suit instituted by the Trustee, to any suit instituted by any Holder or group of Holders for the enforcement of the payment of the principal of, or any premium or interest on, any Security on or after the due date for such payment.

          SECTION 5.15. Waiver of Stay or Extension Laws.

          The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, 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 will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE VI

The Trustee

          The duties and responsibilities of the Trustee shall be as expressly set forth in this Indenture and as provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, subject to Section 6.3.

          SECTION 6.2. Notice of Defaults.

          If a Default or Event of Default has occurred and the Trustee has received notice of the Default or Event of Default in accordance with this Indenture, the Trustee must mail to each Holder a notice of the Default or Event of Default within 30 days after the occurrence of the Event of Default. However, the Trustee need not mail the notice if the Default or Event of Default (a) has been cured or waived; or (b) is not in the payment of any amounts due with respect to any Security and the Trustee in good faith determines that withholding the notice is in the best interests of Holders. In addition, the Trustee shall give the Holders of Securities of such series notice of such Default or Event of Default actually known to it as and to the extent provided by the Trust Indenture Act.

          SECTION 6.3. Certain Rights of Trustee.

          Subject to the provisions of Section 6.1:

               (1) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

               (2) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order, and any resolution of the Company’s Board of Directors may be sufficiently evidenced by a Board Resolution;

               (3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers’ Certificate;

               (4) the Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

               (5) other than its duties in the case of a default pursuant to Section 5.2, 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 Holder, unless such Holders offer to the Trustee indemnity reasonably satisfactory to the Trustee;

               (6) 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 further inquiry or investigation into such facts or matters as it may see fit;

               (7) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder;

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

               (9) 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;

               (10) the permissive rights of the Trustee to do the things enumerated in this Indenture shall not be construed as a duty unless so specified herein. The Trustee shall not be liable in connection with the performance of its duties hereunder, except for its own negligence or willful misconduct;

               (11) whenever in the administration of the trusts imposed upon it by this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering any action hereunder, such matter may be deemed to be conclusively proved and established by an Officers’ Certificate, and such Officers’ Certificate shall be full warrant to the Trustee for any action taken or

suffered in good faith under the provisions of the Indenture in reliance upon such Officers’ Certificate, but in its discretion the Trustee may, in lieu thereof, accept other evidence of such matter or may request such additional evidence as it may deem reasonable;

               (12) in no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential 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;

               (13) the rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder;

               (14) the Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder; and

               (15) the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

          SECTION 6.4. Not Responsible for Recitals or Issuance of Securities.

          The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity, sufficiency or priority of this Indenture or of the Securities, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder, and that the statements made by it or to be made by it in any Statement of Eligibility on Form T-1 supplied to the Company are true and accurate as of the date thereof. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof.

          SECTION 6.5. May Hold Securities and Act as Trustee Under Other Indentures.

          The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 6.8 and 6.13, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

          Subject to the limitations imposed by the Trust Indenture Act, nothing in this Indenture shall prohibit the Trustee from becoming and acting as trustee under other

indentures under which other securities, or certificates of interest of participation in other securities, of the Company are outstanding in the same manner as if it were not Trustee hereunder.

          SECTION 6.6. Money Held in Trust.

          Subject to the provisions of the last paragraphs of Sections 10.3 and 12.5, all money received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. 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 6.7. Compensation and Reimbursement.

          The Company agrees:

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

               (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or willful misconduct; and

               (3) to indemnify the Trustee for, and to hold it harmless against, any and all loss, liability, damage, claim (including taxes (other than taxes based on the income of the Trustee)) or expense incurred without negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim (whether asserted by the Company, a Guarantor, a Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder.

          When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 5.1(5) or Section 5.1(6), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law.

          The Trustee shall have a lien prior to the Securities as to all property and funds held by it hereunder for any amount owing it or any predecessor Trustee pursuant

to this Section 6.7, except with respect to funds held in trust for the benefit of the Holders of particular Securities.

          The provisions of this Section shall survive the termination of this Indenture.

          SECTION 6.8. Conflicting Interests.

          If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest within 90 days or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series.

          SECTION 6.9. Corporate Trustee Required; Eligibility.

          There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be the Trustee hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has (or if the Trustee is a member of a bank holding company system, its bank holding company has) a combined capital and surplus of at least $50,000,000 and shall be subject to supervision or examination by a Federal or State authority. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series 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.

          SECTION 6.10. Resignation and Removal; Appointment of Successor.

          No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.11.

          The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee 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 of such series.

          The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Trustee being removed 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 of such series.

          If at any time:

               (1) the Trustee shall fail to comply with Section 6.8 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months,

               (2) the Trustee shall cease to be eligible under Section 6.9 and shall fail to resign after written request therefor by the Company or by any such Holder, or

               (3) the Trustee shall become incapable of acting or shall be adjudged bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 5.14, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

          If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 6.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.11, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed

by the Company or the Holders and accepted appointment in the manner required by Section 6.11, the retiring Trustee may petition, or any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

          The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 1.6. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

          SECTION 6.11. Acceptance of Appointment by Successor.

          In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee, but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

          In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (i) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (ii) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (iii) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become

effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

          Upon the reasonable written request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be.

          No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

          SECTION 6.12. Merger, Conversion, Consolidation or Succession to Business.

          Any corporation into which the Trustee 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 Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

          SECTION 6.13. Preferential Collection of Claims Against the Company.

          If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

          SECTION 6.14. Appointment of Authenticating Agent.

          The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.5, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder.

Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having (or if the Authenticating Agent is a member of a bank holding company system, its bank holding company has) a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

          Any corporation into which an Authenticating 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 such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 1.6 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

          The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section.

          If an appointment with respect to one or more series is made pursuant to this Section 6.14, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

          This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

          The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders contained in the most recent list furnished to the Trustee as provided in Section 7.1, if any, and the names and addresses of Holders received by the Trustee in its capacity as Security Registrar. The Trustee may destroy any list furnished to it as provided in Section 7.1 upon receipt of a new list so furnished.

          The rights of Holders to communicate with other Holders with respect to their rights under this Indenture or under the Securities, and the corresponding rights and privileges of the Trustee, shall be as provided by the Trust Indenture Act.

          Every Holder of Securities, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any agent of either of them shall be held accountable by reason of any disclosure of information as to the names and addresses of Holders made pursuant to the Trust Indenture Act.

          SECTION 7.3. Reports by Trustee.

          The Trustee shall transmit to Holders of Securities, as their names and addresses appear in the Securities Register, such reports concerning the Trustee and its actions under this Indenture as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant thereto.

          SECTION 7.4. Reports by Express Scripts or the Company.

          Prior to the consummation of the Mergers, Express Scripts and, following the consummation of the Mergers, the Company will file with the Trustee and the Commission, and transmit to Holders, such information, documents and other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act, at the times and in the manner provided pursuant to the Trust Indenture Act; provided that any such information, documents or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within

15 days after the same is so required to be filed with the Commission; provided further that any such information, documents or reports filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval (or EDGAR) system shall be deemed to be filed with the Trustee, provided further that the Trustee shall have no duty to determine whether such filing has occurred.

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

          (5) add to, change or eliminate any of the provisions of this Indenture in respect of one or more series of Securities, provided that any such addition, change or elimination (A) shall neither (i) apply to any Security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor (ii) modify the rights of the Holder of any such Security with respect to such provision or (B) shall become effective only when there is no such Security Outstanding;

     (3) modify any of the provisions of this Section or Section 5.13, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section, or the deletion of this proviso, in accordance with the requirements of Sections 6.11 and 9.1(8); or

          A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series.

          It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

          SECTION 9.3. Execution of Supplemental Indentures.

          In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall receive, and (subject to Sections 6.1 and 6.3) shall be fully protected in conclusively relying upon, an Opinion of Counsel stating that

ARTICLE X

Covenants

          SECTION 10.1. Payment of Principal, Premium and Interest.

          The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of and any premium and interest on the Securities of that series in accordance with the terms of the Securities and this Indenture.

          Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depository. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof as such address appears in the Security Register; provided, however, that payments on a certificated

Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

          SECTION 10.2. Maintenance of Office or Agency.

          The Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will 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 shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee 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 the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes.

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

          If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

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

          The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) hold all sums held by it for the payment of the principal of (and premium, if any) or interest on Securities of that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment of principal (and premium, if any) or interest on the Securities of that series; and (3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series.

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

          Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Security of any series and remaining unclaimed for a period ending on the earlier of the date that is 10 Business Days prior to the date such money would escheat to the State or two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.

          SECTION 10.4. Statement by Officers as to Default.

          The Company will promptly notify the Trustee in writing upon its becoming aware of the occurrence of any Default or Event of Default. In addition, the Company shall furnish to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date of the Indenture, an Officers’ Certificate stating whether the officers certifying therein have actual knowledge of any Default or Event of Default by the Company in performing any of its obligations under the Indenture or the Securities and describing any such Default or Event of Default.

          SECTION 10.5. Existence.

          Subject to Article VIII, the Company will do or cause to be done all things reasonably necessary to preserve and keep in full force and effect its corporate existence.

          SECTION 10.6. Payment of Taxes and Other Claims.

          SECTION 10.7. Calculation of Original Issue Discount.

          The Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods), if any, accrued on Outstanding Securities as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Code.

Such notice shall state:

     (i) a description of the transaction or transactions that constitute the Change of Control Triggering Event for such series;

     (ii) that the Change of Control Offer is being made pursuant to this Section 10.10 and that all Securities of such series validly tendered will be accepted for payment;

     (i) accept for payment all Securities of such series or portions of such Securities properly tendered pursuant to the Change of Control Offer;

     (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities of such series or portions of such Securities properly tendered; and

               The Paying Agent will promptly mail to each Holder of Securities properly tendered the Change of Control Payment for such Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each

Holder of Securities properly tendered a new Security equal in principal amount to any unpurchased portion of any Securities surrendered; provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000.

               (4) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of Securities as a result of a Change of Control Triggering Event.

          Notwithstanding the preceding paragraph, any Guarantee by a Guarantor that was issued pursuant to this Section 10.11 solely as a result of its guarantee or incurrence of, or granting of a Lien in respect of, any such Indebtedness shall be

automatically and unconditionally released upon the release or discharge of the guarantee that resulted in the creation of such Subsidiary’s Guarantee (or upon such Subsidiary ceasing to be an issuer or a borrower or the release of Liens granted by such Subsidiary, as the case may be), except a discharge or release as a result of payment under such guarantee.

          The election of the Company to redeem any Securities shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company of the Securities of any series (including any such redemption affecting only a single Security), the Company shall, at least 40 days (or at least 45 days if less than all the Securities of any series are to be redeemed) prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the aggregate principal amount of Securities of such series to be redeemed.

          SECTION 11.3. Selection by Trustee of Securities to Be Redeemed.

          If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected not more than 90 days prior to the Redemption Date by the Trustee from among the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination for such Securities or any integral multiple thereof) of the principal amount of such Securities of a denomination larger than the minimum authorized denomination.

          The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the aggregate principal amount thereof to be redeemed.

          In the case of any redemption in part affecting only a single Security, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security.

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

          SECTION 11.4. Notice of Redemption.

          Failure to give notice by mailing in the manner herein provided to the Holder of any Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portion thereof.

          All notices of redemption shall identify the Securities to be redeemed and shall state:

               (1) the Redemption Date;

               (2) the Redemption Price (including accrued interest, if any);

               (3) the aggregate principal amount of the Securities of any series to be redeemed;

               (4) if less than all of the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the portions of principal amounts) of the particular Securities to be redeemed;

               (5) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and that interest thereon will cease to accrue on and after said date;

               (6) the place or places where each such Security is to be surrendered for payment of the Redemption Price;

               (7) the CUSIP, ISIN or Common Code numbers of such Securities, if any (or any other number used by the Depository to identify such Securities); and

               (8) if notice of redemption of such Securities to be redeemed has been given by the Company pursuant to this Section 11.4 and funds sufficient to pay the Redemption Price (including any accrued and unpaid interest) of all such Securities to be redeemed on the Redemption Date are irrevocably available for the redemption of the Securities called for redemption on the Redemption Date, that the Securities called

for redemption shall cease to bear interest on and after such Redemption Date and that the only remaining right of the Holders will be to receive payment of the Redemption Price.

          Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, on Company Request provided to the Trustee at least ten days before the notice of redemption is to be given to Holders, by the Trustee at the expense of the Company.

          SECTION 11.5. Deposit of Redemption Price.

          On or before 11:00 a.m., New York time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date.

          SECTION 11.6. Securities Payable on Redemption Date.

          Notice of redemption having been given as aforesaid, the Securities to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and, if funds sufficient to pay the Redemption Price (including any accrued and unpaid interest) of all of such Securities to be redeemed on the Redemption Date are irrevocably available for the redemption of the Securities called for redemption on the Redemption Date, from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued and unpaid interest to the Redemption Date; provided, however, that, unless otherwise specified in or as contemplated by Section 3.1, installments of interest whose Interest Payment Date is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.7.

          If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal thereof shall, until paid, bear interest from the Redemption Date at the rate borne by the Security.

          SECTION 11.7. Securities Redeemed in Part.

          Any Security which is to be redeemed only in part shall be surrendered at an office or agency in accordance with the notice of redemption (with, if the Company or the Trustee shall so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or other appropriate person), and the Company shall execute, and the Trustee shall

authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series, having endorsed thereon the Guarantee executed by the Guarantors and of like tenor, of any authorized denominations as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

For this purpose, such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until all the Securities of such series have in fact been paid in full: (1) the rights of Holders of such Securities to receive, solely from the trust fund described in Section 12.4 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are due, (2) the Company’s obligations with respect to such Securities under Sections 3.4, 3.5, 3.6, 3.8, 3.9, 10.2 and 10.3, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article.

For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Article or Section (to the extent so specified in the case of Section 5.1(4)), whether directly or indirectly by reason of any reference elsewhere herein to any such Article or Section or by reason of any reference in any such Article or Section to any other

provision herein or in any other document, but the remainder of this Indenture and the Securities of such shall be unaffected thereby.

               (6) such Legal Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act);

               (7) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, the Indenture or any other agreement or instrument to which the Company is a party or by which it is bound;

          SECTION 12.5. Deposited Money and U.S. Government Obligations to be Held in Trust; Miscellaneous Provisions.

          Subject to the provisions of the last paragraph of Section 10.3, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 12.6, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 12.4 in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 12.4 or the principal and interest received in respect thereof other

than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding Securities.

          Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company and any Paying Agent upon Company Request any money or U.S. Government Obligations held by it as provided in Section 12.4 with respect to any Securities 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 in excess of the amount thereof which would then be required to be deposited to effect the Legal Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities.

          SECTION 12.6. Reinstatement.

          If the Trustee or the Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 12.2 or 12.3 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 12.5 with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust.

ARTICLE XIII

Guarantee

          SECTION 13.1. Unconditional Guarantee.

               (1) For value received, each of the Guarantors hereby jointly and severally and fully and unconditionally guarantees (each a “Guarantee”), to each Holder of a Security authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture or the Securities or the obligations of the Company or any other Guarantor to the Holders or the Trustee hereunder or thereunder, that: (a) the principal of, premium, if any, and interest on the Securities will be duly and promptly paid in full when due, whether at Stated Maturity, upon redemption, by acceleration or otherwise, and interest on the overdue principal and (to the extent permitted by law) interest, if any, on the Securities and all other obligations of the Company or the Guarantor to the Holders of or the Trustee hereunder or thereunder (including fees, expenses or others) (collectively, the “Obligations”) will be promptly paid in full or performed, all in

accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Obligations (with or without notice to such Guarantor), the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. If the Company shall fail to pay when due, or to perform, any Obligations, for whatever reason, each Guarantor shall be jointly and severally obligated to pay in cash, or to perform or cause the performance of, the same promptly. An Event of Default under this Indenture or the Securities of a particular series shall entitle the Holders of the Securities of such series to accelerate the Obligations of the Guarantor hereunder in the same manner and to the same extent as the Obligations of the Company.

               (2) Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Securities with respect to any provisions of this Indenture or the Securities, any release of any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same, whether or not a Guarantee is affixed to any particular Security, or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

               (3) Each Guarantor further agrees that, as between it, on the one hand, and the Holders of the Securities and the Trustee, on the other hand, (a) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article V for the purposes of the Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations and (b) in the event of any acceleration of such Obligations as provided in Article V, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purposes of its Guarantee.

          SECTION 13.2. Waiver.

          To the fullest extent permitted by applicable law, each of the Guarantors waives diligence, presentment, demand of, payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that the Guarantee will not be discharged except by complete performance of the Obligations contained in the Securities and this Indenture.

          SECTION 13.3. Guarantee of Payment.

          Each of the Guarantors further agrees that its Guarantee constitutes a guarantee of payment, performance and compliance when due and not a guarantee of collection, and waives any right to require that any resort be had by the Trustee or any Holder of the Securities to the security, if any, held for payment of the Obligations.

          SECTION 13.4. No Discharge or Diminishment of Guarantee.

          Subject to Section 13.10 of this Indenture, the obligations of each of the Guarantors hereunder shall not be subject to any reduction, limitation, termination, impairment or for any reason (other than the payment in full in cash of the Obligations), including any claim of waiver, release, surrender, alteration or compromise of any of the Obligations, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each of the Guarantors hereunder shall not be discharged or impaired or otherwise affected by the failure of the Trustee or any Holder of the Securities to assert any claim or demand or to enforce any remedy under this Indenture or the Securities, any other guarantee or any other agreement, by any waiver or modification of any provision thereof, by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or omission or delay to do any other act that may or might in any manner or to any extent vary the risk of any Guarantor or that would otherwise operate as a discharge of any Guarantor as a matter of law or equity (other than the payment in full in cash of all the Obligations).

          SECTION 13.5. Defenses of Company Waived.

          To the extent permitted by applicable law, each of the Guarantors waives any defense based on or arising out of any defense of the Company or any other Guarantor or the unenforceability of the Obligations or any part thereof from any cause, or the cessation from any cause of the liability of the Company, other than final payment in full in cash of the Obligations. Each of the Guarantors waives any defense arising out of any such election even though such election operates to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of each of the Guarantors against the Company or any security.

          SECTION 13.6. Continued Effectiveness.

          Subject to Section 13.10 of this Indenture, each of the Guarantors further agrees that its Guarantee hereunder shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Obligation is rescinded or must otherwise be restored by the Trustee or any Holder of the Securities upon the bankruptcy or reorganization of the Company or otherwise.

          SECTION 13.7. Subrogation.

          In furtherance of the foregoing and not in limitation of any other right of each of the Guarantors by virtue hereof, upon the failure of the Company to pay any Obligation when and as the same shall become due, whether at maturity, by acceleration, after notice of prepayment or otherwise, each of the Guarantors hereby promises to and will, upon receipt of written demand by the Trustee or any Holder of the Securities, forthwith pay, or cause to be paid, to the Holders in cash the amount of such unpaid

Obligations, and thereupon the Holders shall assign (except to the extent that such assignment would render a Guarantor a “creditor” of the Company within the meaning of Section 547 of Title 11 of the United States Code as now in effect or hereafter amended or any comparable provision of any successor statute) the amount of the Obligations owed to it and paid by such Guarantor pursuant to this Guarantee to such Guarantor, such assignment to be pro rata to the extent the Obligations in question were discharged by such Guarantor, or make such other disposition thereof as such Guarantor shall direct (all without recourse to the Holders, and without any representation or warranty by the Holders). If (a) a Guarantor shall make payment to the Holders of all or any part of the Obligations and (b) all the Obligations and all other amounts payable under this Indenture shall be paid in full, the Trustee will, at such Guarantor’s request, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Obligations resulting from such payment by such Guarantor.

          SECTION 13.8. Information.

          Each of the Guarantors assumes all responsibility for being and keeping itself informed of the Company’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Obligations and the nature, scope and extent of the risks that each of the Guarantors assumes and incurs hereunder, and agrees that the Trustee and the Holders of the Securities will have no duty to advise the Guarantors of information known to it or any of them regarding such circumstances or risks.

          SECTION 13.9. Subordination.

          Upon payment by any Guarantor of any sums to the Holders, as provided above, all rights of such Guarantor against the Company, arising as a result thereof by way of right of subrogation or otherwise, shall in all respects be subordinated and junior in right of payment to the prior payment in full in cash of all the Obligations to the Trustee; provided, however, that any right of subrogation that such Guarantor may have pursuant to this Indenture is subject to Section 13.7 hereof.

          SECTION 13.10. Release of Guarantor.

          (1) A Guarantor shall, upon the occurrence of any of the following events, be automatically and unconditionally released and discharged from all obligations under this Indenture and its Guarantee without any action required on the part of the Trustee or any Holder; provided that such Guarantor would not, immediately after such release and discharge, be required to become a Guarantor pursuant to Section 10.11 hereof if such Guarantor had incurred its then-existing guarantees, Indebtedness and Liens at the time of such release and discharge:

     (i) upon notice by the Company to the Trustee, at any time such Guarantor is not a borrower, issuer or guarantor under, and has not granted any then-existing Lien to secure any obligations pursuant to, (1) the Express Scripts Existing Revolving Credit Facility or any refinancing or replacement thereof (including as a result of any release from such obligations in connection with being designated an “exempt subsidiary” by Express Scripts (as defined in the Express Scripts Existing Revolving Credit Facility)), (2) the Medco Term Loan and Revolving Credit Facility or any refinancing or replacement thereof, (3) either of the Facilities or any refinancing or replacement thereof, or (4) any other Indebtedness having an aggregate principal amount outstanding in excess of 15% of the Consolidated Net Worth of (x) prior to the consummation of the Mergers, Express Scripts (y) or following the consummation of the Mergers, the Company, in each case as of the end of such entity’s most recent quarter for which financial statements are available (other than obligations arising under this Indenture and the Securities), and such Guarantor is released or discharged from each guarantee and Lien granted by such Guarantor with respect to all such Indebtedness other than obligations arising under this Indenture and any Securities issued under the Indenture except where resulting from a discharge or release as a result of payment under such guarantee;

     (ii) upon the occurrence of the circumstances described in Section 10.11 hereof, of which the Company shall promptly notify the Trustee; or

     (iii) upon the sale, transfer or disposition of all or substantially all of the equity interests or assets of the Guarantor to another Person (other than to the Company, any of its Subsidiaries or Affiliates).

          (2) A Guarantor shall be automatically and unconditionally released and discharged from all obligations under this Indenture and its Guarantee without any action required on the part of the Trustee or any Holder upon any Covenant Defeasance or Legal Defeasance with respect to the Securities, subject to reinstatement pursuant to Section 12.6 of the Indenture.

          (3) The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of a request of the Company accompanied by an Officers’ Certificate certifying as to the compliance with this Section. Any Guarantor not so released will remain liable for the full amount of the principal of, premium, if any, and interest on the Securities provided in this Indenture and its Guarantee.

          SECTION 13.11. Limitation of Guarantor’s Liability.

          (1) Each Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the Guarantee by such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Title 11 of the United States Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent

Transfer Act or any similar federal or state law to the extent applicable to any Guarantor. To effectuate the foregoing intention, the Holders and such Guarantor hereby irrevocably agree that the obligations of such Guarantor under this Indenture and its Guarantee shall be limited to the maximum aggregate amount which, after giving effect to all other contingent and fixed liabilities of such Guarantor, and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such Guarantor under its Guarantee or pursuant to its contribution obligations under this Indenture, will result in the obligations of such Guarantor under its Guarantee not constituting such fraudulent transfer or conveyance.

          (2) The Guarantee is expressly limited so that in no event, including the acceleration of the maturity of the Securities, shall the amount paid or agreed to be paid in respect of interest on the Securities (or fees or other amounts deemed payment for the use of funds) exceed the maximum permissible amount under applicable law, as in effect on the date hereof and as subsequently amended or modified to allow a greater amount of interest (or fees or other amounts deemed payment for the use of funds) to be paid under the Guarantee. If for any reason the amount in respect of interest (or fees or other amounts deemed payment for the use of funds) required by the Guarantee exceeds such maximum permissible amount, the obligation to pay interest under the Guarantee (or fees or other amounts deemed payment for the use of funds) shall be automatically reduced to such maximum permissible amount and any amounts collected by any holder of any Security in excess of the permissible amount shall be automatically applied to reduce the outstanding principal on such Security.

          SECTION 13.12. Contribution from Other Guarantors.

          Each Guarantor that makes a payment or distribution under its Guarantee shall be entitled to seek contribution from each other non-paying Guarantor in a pro rata amount based on the net assets of each Guarantor, determined in accordance with generally accepted accounting principles in effect in the United States of America as of the date hereof so long as the exercise of such right does not impair the rights of the Holders under the Guarantee.

          SECTION 13.13. No Obligation to Take Action Against the Company.

          Neither the Trustee, any Holder nor any other Person shall have any obligation to enforce or exhaust any rights or remedies or take any other steps under any security for the Obligations or against the Company or any other Person or any Property of the Company or any other Person before the Trustee, such Holder or such other Person is entitled to demand payment and performance by any or all Guarantors of their liabilities and obligations under their Guarantee.

          SECTION 13.14. Execution and Delivery of the Guarantee.

          (1) To further evidence the Guarantee set forth in this Article, each Guarantor hereby agrees that a notation of such Guarantee substantially in the form of Exhibit 2 shall be endorsed on each Security authenticated and delivered by the Trustee and executed by either manual or facsimile signature of an officer, manager or member, as applicable, of each Guarantor.

          (2) Each of the Guarantors hereby agrees that its Guarantee set forth in this Article shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Guarantee.

          (3) If an officer of a Guarantor whose signature is on this Indenture or a Guarantee no longer holds that office or is no longer a manager or member, as applicable, at the time the Trustee authenticates such Guarantee or at any time thereafter, such Guarantor’s Guarantee of such Security shall be valid nevertheless.

          (4) The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in this Indenture on behalf of each Guarantor.

          SECTION 13.15. Successor Guarantor.

          Unless otherwise released and discharged from its obligations in accordance with this Indenture, upon any consolidation or merger by any Guarantor with or into any other Person, the successor Person formed by such consolidation or merger shall sign a supplemental indenture and guarantee and succeed to, and be substituted for, and may exercise every right and power of, the Guarantor under this Indenture with the same effect as if such successor Person has been named as a Guarantor herein, and thereafter the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the Securities (to the extent the Guarantor was the predecessor Person).

          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed all as of the day and year first above written.

The aggregate principal amount of Initial Securities Outstanding at any time may not exceed $[       ] in aggregate principal amount, except for Securities issued, authenticated and delivered upon registration of transfer, or in exchange for, or in lieu of, other Securities of the series pursuant to Sections 3.4, 3.5, 3.6, 9.6 or 11.7 of the Base Indenture and except for any Securities which, pursuant to Section 3.3 of the Base Indenture, are deemed never to have been authenticated and delivered.

          The Indenture contains covenants that limit the ability of the Company and any Restricted Subsidiary to create liens on assets and to engage in sale/leaseback transactions. The Indenture also contains covenants that limit the ability of the Company and, prior to the consummation of the Mergers, of Express Scripts to consolidate, merge or transfer all or substantially all of their respective assets. These covenants are subject to important exceptions and qualifications.

          All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture. In the event of a conflict or inconsistency between this Security and the Indenture, the provisions of the Indenture shall govern.

               (2) Optional Redemption. At any time prior to Maturity, the Company may at its option redeem all or a part of the Securities upon not more than 60 nor less than 30 days prior notice, at a Redemption Price equal to the greater of: (i) 100% of the aggregate principal amount of any Securities being redeemed, plus accrued and unpaid interest on the Securities to the Redemption Date; or (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Securities to be redeemed (exclusive of unpaid interest accrued thereon to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year comprised of twelve 30-day months) at the Treasury Rate plus [       ] basis points, plus unpaid interest on the Securities to be redeemed, accrued to the Redemption Date.

               (3) Mandatory Redemption. Except as provided in Section 4 below, the Company is not required to make mandatory redemption or sinking fund payments with respect to the Securities.

               (4) Change of Control Triggering Event. In the event of a Change of Control Triggering Event, the Holders may require the Company to purchase for cash all or a portion of their Securities at a purchase price equal to 101% of the aggregate principal amount of the

Securities repurchased, plus accrued and unpaid interest, if any, pursuant to the provisions of Section 10.10 of the Base Indenture.

               (5) Global Security. If this Security is a Global Security, then the transfer and exchange of this Security or beneficial interests herein shall be effected through the Depository in accordance with the Indenture (including applicable restrictions on transfer set forth therein, if any) and the procedures of the Depository therefor.

               (6) Defaults and Remedies. If an Event of Default with respect to this Security occurs and is continuing, the principal of and any unpaid premium and interest on (or, if this Security is an Original Issue Discount Security, such portion of the principal amount of such Securities as may be specified in the terms thereof) all Outstanding Securities of this series, may be declared due and payable in the manner and with the effect provided in the Indenture. The Holders of at least a majority in principal amount of the outstanding securities of this series may rescind or annul that acceleration if all Events of Default with respect to this series of Securities other than the non-payment of accelerated principal have been cured or waived as provided in the Indenture.

          As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default, and, among other things, the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities shall have made a written request to the Trustee to pursue a remedy in respect of such Event of Default as Trustee. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any amounts due on the Securities on or after the respective due dates expressed herein.

               (7) Discharge and Defeasance. Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of the Company’s and the Guarantors’ obligations under the Securities, the Guarantees and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be.

               (8) Amendment, Supplement and Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the written consent of the Holders of at least a majority in aggregate principal amount of the Outstanding Securities of each series affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Outstanding Securities of each series to be affected, on behalf of the Holders of all such Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or

not notation of such consent or waiver is made upon this Security or such other Security. Certain modifications or amendments to the Indenture require the consent of the Holder of each Outstanding Security affected.

               Notwithstanding any other provision of the Indenture or this Security, the Holder of this Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 3.7 of the Indenture) interest on any such Security on the Stated Maturity date expressed herein (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

               (9) Denomination, Registration and Transfer. The Securities are in registered form without coupons in minimum denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, this Security is transferable only upon surrender of this Security for registration of transfer. Upon surrender for registration of transfer of this Security at the office or agency of the Company in a Place of Payment for this Security, the Company, if the requirements of the Indenture are met, shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series of authorized denominations and of like tenor and aggregate principal amount, and having endorsed thereon a Guarantee executed by the Guarantors.

               If the requirements of this Indenture are met, then, at the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive, and having endorsed thereon a Guarantee executed by the Guarantor. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

               Prior to due presentment of this Security for registration of transfer, the Company, the Guarantors, the Trustee and any agent of the Company, the Guarantors or the Trustee may treat the Person in whose name such Security is registered as the owner thereof for all purposes, whether or not such Security be overdue, and none of the Company, the Guarantors or the Trustee or other such agent shall be affected by notice to the contrary.

               (10) Guarantee. Payment of this Security is jointly and severally and fully and unconditionally guaranteed by the Guarantors that have become and continue to be Guarantors pursuant to the Indenture. Guarantors may be released from their obligations under the Indenture and their Guarantees under the circumstances specified under the Indenture.

               (11) No Recourse Against Others. None of the Company’s or any Guarantor’s past, present or future directors, officers, employees or shareholders, as such, shall have any liability for any of the Company’s or any Guarantor’s obligations under the Indenture or the Securities or for any claim based on, or in respect or by reason of, such obligations or their

creation. By accepting a Security, each Holder waives and releases all such liability. This waiver and release is part of the consideration for the issuance of the Securities.

               (12) Governing Law. THE INDENTURE, THIS SECURITY AND ANY GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
