Without limiting the generality of the foregoing, the 2010 Notes offered and sold to Qualified Institutional Buyers in reliance on Rule 144A (“2010 Rule 144A Notes”), and the 2015 Notes offered and sold to Qualified Institutional Buyers in reliance on Rule 144A (“2015 Rule 144A Notes” and, together with the 2010 Rule 144A Notes, the “Rule 144A Notes”) shall bear the legend set forth inExhibit B and include the form of assignment, the 2010 Notes offered and sold in offshore transactions in reliance on Regulation S (“2010 Regulation S Notes”) and the 2015 Notes offered and sold in offshore transactions in reliance on Regulation S (“2015 Regulation S Notes” and, together with the 2010 Regulation S Notes, the “Regulation S Notes”) shall bear the legend and include the form of assignment set forth inExhibit C. Each Note shall be dated the date of its authentication.

          The terms and provisions contained in the Notes shall constitute, and are expressly made, a part of this Indenture and, to the extent applicable, the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and agree to be bound thereby.

          The Notes may be presented for registration of transfer and exchange at the offices of the Registrar.

SECTION 2.03.Execution and Authentication.

          The Notes shall be executed on behalf of the Company by its Chairman of the Board, Chief Executive Officer, Chief Financial Officer, President or any Vice President. The signature of any of these officers on the Notes may be manual or facsimile.

          If an Officer whose signature is on a Note was an Officer at the time of such execution but no longer holds that office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless.

-25-

          No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Note shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Note to the Trustee for cancellation as provided in Section 2.12, for all purposes of this Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

          The Notes shall be issuable only in fully registered form without coupons in denominations of $1,000 and any integral multiple of $1,000.

SECTION 2.04.Registrar and Paying Agent.

          The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”), and an office or agency where Notes may be presented for payment (the “Paying Agent”) and an office or agency where notices and demands to or upon the Company, if any, in respect of the Notes and this Indenture may be served. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may have one or more additional Paying Agents. The term “Paying Agent” includes any additional Paying Agent.

          The Company shall enter into an appropriate agency agreement, which shall incorporate the provisions of the TIA, with any Agent that is not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any such Agent. If the Company fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such and shall be entitled to appropriate compensation in accordance with Section 7.07.

          The Company initially appoints the Trustee as Registrar, Paying Agent and Agent for service of notices and demands in connection with the Notes and this Indenture, and the Corporate Trust Office of the Trustee as the office or agency of the Company for such purposes, and the Company may change the Paying Agent without prior notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent.

SECTION 2.05.Paying Agent To Hold Money in Trust.

          Each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of or premium or interest on the Notes (whether such money has been paid to it by the Company or any other obligor on

-26-

the Notes), and the Company and the Paying Agent shall notify the Trustee of any default by the Company (or any other obligor on the Notes) in making any such payment. Money held in trust by the Paying Agent need not be segregated except as required by law and in no event shall the Paying Agent be liable for any interest on any money received by it hereunder;providedthat if the Company or an Affiliate thereof acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require the Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed and the Trustee may at any time during the continuance of any Event of Default specified in Section 6.01(1) or (2), upon written request to the Paying Agent, require the Paying Agent to pay forthwith all money so held by it to the Trustee and to account for any funds disbursed. Upon making such payment, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.06.Holder Lists.

          The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of the Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least five Business Days before each Interest Payment Date, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders;providedthat, as long as the Trustee is the Registrar, no such list need be furnished.

SECTION 2.07.Transfer and Exchange.

          Subject to Sections 2.16 and 2.17, when Notes are presented to the Registrar with a request from the Holder of such Notes to register a transfer or to exchange them for an equal principal amount of Notes of other authorized denominations of the same series, the Registrar shall register the transfer as requested. Every Note presented or surrendered for registration of transfer or exchange shall be duly endorsed or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorneys duly authorized in writing. To permit registrations of transfers and exchanges, the Company shall issue and execute and the Trustee shall authenticate new Notes evidencing such transfer or exchange at the Registrar’s request. No service charge shall be made to the Holder for any registration of transfer or exchange. The Company may require from the Holder payment of a sum sufficient to cover any transfer taxes or other governmental charge that may be imposed in relation to a transfer or exchange, but this provision shall not apply to any exchange pursuant to Section 2.11, 3.06 or 8.05 (in which events the Company shall be responsible for the payment of such taxes). The Registrar shall not be required to exchange or register a transfer of any Note for a period of 15 days immediately preceding the redemption of Notes, except the unredeemed portion of any Note being redeemed in part.

-27-

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

          Except as expressly provided herein, neither the Trustee nor the Registrar shall have any duty to monitor the Company’s compliance with or have any responsibility with respect to the Company’s compliance with any Federal or state securities laws.

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

SECTION 2.08.Replacement Notes.

          If a mutilated Note is surrendered to the Registrar or the Trustee, or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the Holder of such Note furnishes to the Company and the Trustee evidence reasonably acceptable to them of the ownership and the destruction, loss or theft of such Note and if the requirements of Section 8-405 of the New York Uniform Commercial Code as in effect on the date of this Indenture are met. If required by the Trustee or the Company, an indemnity bond shall be posted, sufficient in the judgment of all to protect the Company, the Trustee or any Paying Agent from any loss that any of them may suffer if such Note is replaced. The Company may charge such Holder for the Company’s reasonable out-of-pocket expenses in replacing such Note and the Trustee may charge the Company for the Trustee’s expenses (including, without limitation, attorneys’ fees and disbursements) in replacing such Note. Every replacement Note shall constitute a contractual obligation of the Company.

SECTION 2.09.Outstanding Notes.

          The Notes outstanding at any time are all Notes that have been authenticated by the Trustee except for (a) those canceled by it, (b) those delivered to it for cancellation, (c) to the extent set forth in Sections 9.01 and 9.02, on or after the date on which the conditions set forth in Section 9.01 or 9.02 have been satisfied, those Notes theretofore authenticated and delivered by the Trustee hereunder and (d) those described in this Section 2.09 as

-28-

not outstanding. Subject to Section 2.10, a Note does not cease to be outstanding because the Company or one of its Affiliates holds the Note.

          If a Note is replaced pursuant to Section 2.08, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser in whose hands such Note is a legal, valid and binding obligation of the Company.

          If the Paying Agent holds, in its capacity as such, on any Maturity Date, money sufficient to pay all accrued interest and principal with respect to the Notes payable on that date and is not prohibited from paying such money to the Holders thereof pursuant to the terms of this Indenture, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue.

SECTION 2.10.Treasury Notes.

          In determining whether the Holders of the required principal amount of Notes have concurred in any declaration of acceleration or notice of default or direction, waiver or consent or any amendment, modification or other change to this Indenture, Notes owned by the Company or any other Affiliate of the Company shall be disregarded as though they were not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent or any amendment, modification or other change to this Indenture, only Notes as to which a Responsible Officer of the Trustee has actually received an Officers’ Certificate stating that such Notes are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee established to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Notes and that the pledgee is not the Company any other obligor on the Notes or any of their respective Affiliates.

SECTION 2.11.Temporary Notes.

          Until definitive Notes are prepared and ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. Until such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges as definitive Notes.

SECTION 2.12.Cancellation.

          The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Notes surrendered

-29-

for registration of transfer, exchange, payment, replacement or cancellation and shall deliver such canceled Notes to the Company. The Company may not reissue or resell, or issue new Notes to replace Notes that the Company has redeemed or paid, or that have been delivered to the Trustee for cancellation (other than in accordance with this Indenture).

SECTION 2.13.Defaulted Interest.

          If the Company defaults on a payment of interest on the Notes, it shall pay the defaulted interest, plus (to the extent permitted by law) any interest payable on the defaulted interest, in accordance with the terms hereof, to the Persons who are Holders on a subsequent special record date, which date shall be at least five Business Days prior to the payment date. The Company shall fix such special record date and payment date in a manner satisfactory to the Trustee. At least 10 days before such special record date, the Company shall mail to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest, and interest payable on defaulted interest, if any, to be paid. The Company may make payment of any defaulted interest in any other lawful manner not inconsistent with the requirements (if applicable) of any securities exchange on which the Notes may be listed and, upon such notice as may be required by such exchange, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this sentence, such manner of payment shall be deemed practicable by the Trustee.

SECTION 2.14.CUSIP Number.

          The Company in issuing the Notes may use a “CUSIP,” “ISIN” or other similar number, and if so, such CUSIP, ISIN or other similar number shall be included in notices of redemption or exchange as a convenience to Holders;providedthat any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP, ISIN or other similar number printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee of any such CUSIP, ISIN or other similar number used by the Company in connection with the issuance of the Notes and of any change in the CUSIP, ISIN or other similar number.

SECTION 2.15.Deposit of Moneys.

          Prior to 11:00 a.m., New York City time, on each Interest Payment Date and Maturity Date, the Company shall have deposited with the Paying Agent in immediately available funds money sufficient to make cash payments, if any, due on such Interest Payment Date or Maturity Date, as the case may be, in a timely manner which permits the Trustee to remit payment to the Holders on such Interest Payment Date or Maturity Date, as the case may be. The principal and interest on Global Notes shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the sole Holder of the Global

-30-

Notes represented thereby. The principal and interest on Physical Notes shall be payable, either in person or by mail, at the office of the Paying Agent.

SECTION 2.16.Book-Entry Provisions for Global Notes.

          (a) The 2010 Rule 144A Notes shall be represented by one or more Notes in registered, global form without interest coupons (collectively, the “2010 Restricted Global Note”). The 2015 Rule 144A Notes shall be represented by one or more Notes in registered, global form without interest coupons (collectively, the “2015 Restricted Global Note” and, together with the 2010 Restricted Global Note, the “Restricted Global Note”). The 2010 Regulation S Notes initially shall be represented by one or more Notes in registered, global form without interest coupons (collectively, the “2010 Regulation S Global Note”). The 2015 Regulation S Notes initially shall be represented by one or more Notes in registered, global form without interest coupons (collectively, the “2015 Regulation S Global Note” and, together with the 2010 Regulation S Global Note, the “Regulation S Global Note”). The Restricted Global Note and the Regulation S Global Note and any other global notes representing the Notes (collectively, the “Global Notes”) shall bear legends as set forth inExhibit D.

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

          None of the Company, the Trustee, the Registrar, any Paying Agent or any agent of any of them shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Notes, for maintaining, supervising or reviewing any records relating to such beneficial owner interests, or for any acts or omissions of a Depository or for any transactions between a Depository and any beneficial owner or between or among beneficial owners. No owner of a beneficial interest in the Notes shall have any rights under this Indenture, and the Depository or its nominee, if any, shall be deemed and treated by the Company, the Trustee, the Registrar, any Paying

-31-

Agent or any agent of any of them as the absolute owner and holder of such Notes for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, the Registrar, any Paying Agent or any agent of any of them from giving effect to any written certification, proxy or other authorization furnished by a Depository, or any of its members and any other Person on whose behalf such member may act, the operation of customary practices of such Persons governing he exercise of the rights of a beneficial owner of any Notes.

          (b) Transfers and exchanges pursuant to Section 2.16 and 2.17 may only be made between Notes of the same series. Transfers of Global Notes shall be limited to transfer in whole, but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in the Global Notes may be transferred or exchanged for Physical Notes in accordance with the rules and procedures of the Depository and the provisions of Section 2.17. In addition, a Global Note shall be exchangeable for Physical Notes if (i) the Depository (x) notifies the Company that it is unwilling or unable to continue as depository for such Global Note or (y) has ceased to be a clearing agency registered under the Exchange Act, and, with respect to (x) or (y), the Company thereupon fails to appoint a successor depository within 90 days of such notice or cessation or (ii) upon the request of the Depository at any time that there shall have occurred and be continuing an Event of Default with respect to the Notes. In all cases, Physical Notes delivered in exchange for any Global Note or beneficial interests therein shall be registered in the names, and issued in any approved denominations, requested by or on behalf of the Depository (in accordance with its customary procedures).

          (c) In connection with any transfer or exchange of a portion of the beneficial interest in any Global Note to beneficial owners pursuant to paragraph (b), the Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a decrease in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Company shall execute, and the Trustee shall upon receipt of a written order from the Company authenticate and make available for delivery, one or more Physical Notes of like tenor and amount.

          (d) In connection with the transfer of Global Notes as an entirety to beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depository in writing in exchange for its beneficial interest in the Global Notes, an equal aggregate principal amount of Physical Notes of authorized denominations.

          (e) Any Physical Note constituting a Restricted Note delivered in exchange for an interest in a Global Note pursuant to paragraph (b), (c) or (d) shall, except as otherwise provided by paragraphs (a) and (c) of Section 2.17, bear the Private Placement Legend or, in

-32-

the case of the Regulation S Global Note, the legend set forth inExhibit C, in each case, unless the Company determines otherwise in compliance with applicable law.

          (f) Any beneficial interest in one of the Global Notes that is transferred to a Person who takes delivery in the form of an interest in another Global Note shall, upon transfer, cease to be an interest in such Global Note and become an interest in such other Global Note and, accordingly, shall thereafter be subject to all transfer restrictions and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.

          (g) The Holder of any Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

SECTION 2.17.Special Transfer Provisions.

          (a)Transfers to QIBs. The following provisions shall apply with respect to the registration or any proposed registration of transfer of a Note constituting a Restricted Note to a QIB (excluding transfers to Non-U.S. Persons):

          (i) the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on such Holder’s Note stating, or to a transferee who has advised the Company and the Registrar in writing, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; and

          (ii) if the proposed transferee is an Agent Member, and the Notes to be transferred consist of Physical Notes which after transfer are to be evidenced by an interest in the Global Note, upon receipt by the Registrar of instructions given in accordance with the Depository’s and the Registrar’s procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note in an amount equal to the principal amount of the Physical Notes to be transferred, and the Trustee shall cancel the Physical Notes so transferred.

          (b)Transfers to Non-QIB Institutional Accredited Investors and Non-U.S. Persons. The following provisions shall apply with respect to the registration of any proposed

          (iii) in the case of a transfer to a Non-U.S. Person, if the proposed transferee is an Agent Member, and the Notes to be transferred consist of Physical Notes which after transfer are to be evidenced by an interest in a Regulation S Global Note, upon receipt by the Registrar of written instructions given in accordance with the Depositary’s and the Registrar’s procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount of such Regulation S Global Note in an amount equal to the principal amount of Physical Notes to be transferred, and the Trustee shall cancel the Physical Notes so transferred.

          (d)General. By its acceptance of any Note bearing the Private Placement Legend, each Holder of such Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Note only as provided in this Indenture.

          (e)Certain Transfers in Connection with and After the Exchange Offer under the Registration Rights Agreement. Notwithstanding any other provision of this Indenture:

          (i) no Exchange Notes issued may be exchanged by the Holder thereof for a Note issued on the Issue Date;

          Concurrently with the issuance of such Notes, the Trustee will cause the aggregate principal amount of the applicable Global Notes bearing the Private Placement Legend to be reduced accordingly, and the Company will execute and the Trustee will authenticate and deliver to the Persons designated by the Holders of Physical Notes so accepted Physical Notes not bearing the Private Placement Legend in the appropriate principal amount.

          The Registrar shall retain for a period of two years copies of all letters, notices and other written communications received pursuant to Section 2.16 or this Section 2.17.

-41-

owned at the Issue Date or acquired after the Issue Date, without ensuring that the Notes (together with, if the Company decides, any other indebtedness created, issued, assumed or guaranteed by the Company or any Restricted Subsidiary and then existing or thereafter created) will be secured by such lien equally and proportionately with (or, at the Company’s option, prior to) such indebtedness.

          (b) The provisions of Section 4.06(a) will not apply to indebtedness secured by any of the following:

     (1) liens on any property acquired, constructed or improved by the Company or any Restricted Subsidiary after the Issue Date to secure indebtedness (including Capital Lease Obligations) incurred for the purpose of financing or refinancing all or any part of the purchase price of such property or of the cost of any construction or improvements on such properties, in each case, to the extent that the indebtedness is incurred prior to or within 270 days after the applicable acquisition, completion of construction or beginning of commercial operation of such property, as the case may be;

     (2) liens on any property existing at the time the Company or any Restricted Subsidiary acquire such property (providedthat such lien is not incurred in anticipation of such transaction and does not extend beyond the property subject thereto or secure any indebtedness that is not secured thereby immediately prior to such transaction);

     (7) extensions, renewals or replacements of any lien existing on the Issue Date or any lien referred to above; however, the principal amount of indebtedness secured thereby may not exceed the principal amount of indebtedness so secured at the time of such extension, renewal or replacement plus the amount of reasonable fees and expenses in connection therewith, and such extension, renewal or replacement will be limited to all or a part of the property (plus improvements and construction on such property) which was subject to the lien so extended, renewed or replaced.

          (c) Notwithstanding the provisions of Section 4.06(a), the Company or any Restricted Subsidiary may, without having to equally and proportionately secure the Notes, issue, assume or guarantee indebtedness secured by a lien not excepted from the restriction set forth above if the total of:

     (1) such indebtedness; plus

          If an Unrestricted Subsidiary is Redesignated as a Restricted Subsidiary or becomes a Restricted Subsidiary as a result of a Fall-Away Event, any liens on the assets of that Subsidiary existing at the time that such Subsidiary was Redesignated or at the time such Fall-Away Event occurs that secure any indebtedness of such Subsidiary (or any refinancing thereof that complies with clause (b)(7) of this Section 4.06) will not result in such Subsidiary

-43-

being required to equally and ratably secure the Notes. However, the amount of indebtedness secured by such liens shall be included in any subsequent determination of whether a future incurrence of indebtedness by the Company or a Restricted Subsidiary meets the test set forth in the first paragraph of this Section 4.06(c).

          (e) To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of this Indenture, the Company will comply with the applicable securities laws and regulations, including with Section 14(e) of the Exchange Act, and will not be deemed to have breached its obligations under the Change of Control provisions of this Indenture by virtue of such conflict.

SECTION 5.01.Consolidation, Merger and Sale of Assets.

          The Company may consolidate or merge with or into any other corporation (or, if a corporate co-issuer formed under the laws of the United States, any state in the United States or the District of Columbia becomes a co-obligor on the Notes, any limited partnership or limited liability company), or lease, sell or transfer all or substantially all of the Company’s property and assets if:

     (a) the Person formed by such consolidation or into which the Company is merged, or the party which acquires by lease, sale or transfer all or substantially all of the Company’s property and assets is a corporation organized and existing under the laws of the United States, any state in the United States or the District of Columbia;

     (5) one or more defaults shall have occurred under any of the agreements, indentures or instruments under which the Company or any Restricted Subsidiary then has outstanding indebtedness in excess of $40 million, individually or in the aggregate, and either:

     (A) such default results from the failure to pay such indebtedness at its stated final maturity and such default has not been cured or the indebtedness repaid in full within ten days of the default; or

     (B) such default or defaults have resulted in the acceleration of the maturity of such indebtedness and such acceleration has not been rescinded or such indebtedness repaid in full within ten days of the acceleration;

-54-

     (6) one or more judgments or orders that exceed $40 million in the aggregate (net of amounts covered by insurance or bonded) for the payment of money have been entered by a court or courts of competent jurisdiction against the Company or any Restricted Subsidiary and such judgment or judgments have not been satisfied, stayed, annulled or rescinded within 60 days after such judgment or judgments become final and nonappealable;

     (7) any Guarantee by a significant subsidiary shall for any reason cease to be, or shall for any reason be asserted in writing by any Guarantor or the Company not to be, in full force and effect and enforceable in accordance with its terms, except to the extent contemplated by this Indenture and any such Guarantee;

     (8) the Company or any significant subsidiary pursuant to or within the meaning of any Bankruptcy Law:

          The foregoing will constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

SECTION 6.02.Acceleration of Maturity; Rescission.

          If an Event of Default with respect to a series of the Notes (other than an Event of Default specified in Sections 6.01(8) and 6.01(9) with respect to the Company) shall have occurred and be continuing, the Trustee or the registered Holders of not less than 25% in aggregate principal amount of such series of Notes, then outstanding may declare to be immediately due and payable the principal amount of all such Notes then outstanding by written notice to the Company and the Trustee, plus accrued but unpaid interest to the date of acceleration. In case an Event of Default specified in Sections 6.01(8) and 6.01(9) with respect to the Company shall occur, such amount with respect to all the Notes shall be automatically due and payable immediately without any declaration or other act on the part of the Trustee or the Holders of the Notes. After any such acceleration, but before a judgment or decree based on acceleration is obtained by the Trustee, the registered Holders of a majority in aggregate principal amount of the 2010 Notes or the 2015 Notes, as the case may be, then outstanding may rescind and annul such acceleration if (i) if the rescission would not conflict with any judgment or decree, (ii) if all existing Events of Default have been cured or waived except nonpayment of principal, premium or interest that has become due solely because of the acceleration, (iii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid, (iv) if the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances and all other amounts due to the Trustee under Section 7.07 and (v) in the event of the cure or waiver of an Event of Default of the type described in either Section 6.01(8) or (9), the Trustee shall have received an Officers’ Certificate to the effect that such Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

          Subject to Section 7.01, in case an Event of Default shall occur and be continuing, the Trustee shall be under no obligation to exercise any of its rights or powers under this Indenture at the request or direction of any of the Holders of the Notes, unless such Holders shall have offered to the Trustee reasonable security or indemnity. Subject to Section 7.07,

-56-

the Holders of a majority in aggregate principal amount of the 2010 Notes or the 2015 Notes, as the case may be then outstanding will 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 such series of Notes.

SECTION 6.03.Other Remedies.

          If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, or premium, if any, and interest on the 2010 Notes and/or the 2015 Notes, as the case may be, or to enforce the performance of any provision of the Notes or this Indenture and may take any necessary action requested of it as Trustee to settle, compromise, adjust or otherwise conclude any proceedings to which it is a party.

          The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. Any such proceeding instituted by the Trustee may be brought in its own name and as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements of the Trustee and its counsel, be for the ratable benefit of the Holders of the Notes in respect of which such judgment has been recovered. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative, to the extent permitted by law. Any costs associated with actions taken by the Trustee under this Section 6.03 shall be reimbursed to the Trustee by the Company.

SECTION 6.04.Waiver of Past Defaults and Events of Default.

          Provided the Notes are not then due and payable by reason of a declaration of acceleration, the Holders of a majority in principal amount of the then outstanding 2010 Notes or the 2015 Notes, as the case may be, may on behalf of the Holders of all the affected Notes of such series waive any past Default with respect to Notes of such series and its consequences by providing written notice thereof to the Company and the Trustee, except a Default (1) in the payment of interest on or the principal of any Note or (2) in respect of a covenant or provision hereof which under this Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note affected. In the case of any such waiver, the Company, the Trustee and the Holders of the 2010 Notes or the 2015 Notes, as the case may be, will be restored to their former positions and rights under this Indenture, respectively;providedthat no such waiver shall extend to any subsequent or other Default or impair any right consequent thereto.

-57-

SECTION 6.05.Control by Majority.

          The Holders of at least a majority in aggregate principal amount of the outstanding series of 2010 Notes or the 2015 Notes, as the case may be, may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes of such series. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of the affected Notes not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received from Holders of the Notes.

SECTION 6.06.Limitation on Suits.

          No Holder of Notes will have any right to institute any proceeding with respect to this Indenture, or for the appointment of a receiver or trustee, or for any remedy hereunder, unless:

               (1) the Holder gives the Trustee written notice of a continuing Event of Default,

               (2) the Holders of at least 25% in aggregate principal amount of outstanding 2010 Notes or the 2015 Notes, as the case may be, make a written request to the Trustee to institute such proceeding or pursue such remedy as trustee,

               (3) such Holder or Holders offer the Trustee indemnity satisfactory to the Trustee against any costs, liability or expense,

               (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity, and

               (5) during such 60-day period the Holders of at least a majority in aggregate principal amount of the outstanding 2010 Notes or the 2015 Notes, as the case may be, do not give the Trustee a direction that is inconsistent with the request.

          However, such limitations do not apply to a suit instituted by a Holder of any Note for enforcement of payment of the principal of, and premium, if any, or interest on, such Note on or after the respective due date expressed in such Note.

-58-

SECTION 6.07. No Personal Liability of Directors, Officers, Employees andStockholders.

          No past, present or future director, manager, trustee, officer, employee, member, partner, agent, shareholder or Affiliate of the Company shall have any liability for any obligations of the Company under the Notes, or this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

SECTION 6.08.Rights of Holders To Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of the principal of or premium, if any, or interest, if any, on such Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Notes shall not be impaired or affected without the consent of the Holder.

SECTION 6.09.Collection Suit by Trustee.

          If an Event of Default in payment of principal, premium or interest specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company (or any other obligor on the Notes) for the whole amount of unpaid principal and accrued interest remaining unpaid.

SECTION 6.10.Trustee May File Proofs of Claim.

          The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and, unless prohibited by law, shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same after deduction of its charges and expenses to the extent that any such charges and expenses are not paid out of the estate in any such proceedings and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07.

          Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan or reorganization, arrangement,

-59-

adjustment or composition affecting the Notes 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 proceedings. All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes 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 in respect of which such judgment has been recovered.

SECTION 6.11.Priorities.

          Any money or property collected by the Trustee pursuant to this Article Six, and any money or other property distributable in respect of the Company’s obligations under this Indenture after an Event of Default shall be applied in the following order:

          FIRST: to the Trustee (including any predecessor Trustee) for amounts due under Section 7.07;

          SECOND: to Holders for amounts due and unpaid on the affected Notes for principal, premium, if any, and interest (including Additional Interest, if any) as to each, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes; and

          THIRD: to the Company.

          The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.11.

SECTION 6.12.Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.12 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.08 or a suit by Holders of more than 10% in principal amount of the Notes then outstanding.

SECTION 6.13.Delay or Omission Not Waiver.

-60-

          No delay or omission of the Trustee or of any Holder of any Notes to exercise any right or remedy occurring upon an 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 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

          (a) If an Event of Default actually known to a Responsible Officer of the Trustee has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

          The Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of such Default or Event of Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

          (d) 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 rights, powers or duties if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity satisfactory to it against such risk or liability is not reasonably assured to it.

          (e) Whether or not therein expressly so provided, Sections 7.01(a), (b), (c), (d) and (e) shall govern every provision of this Indenture that in any way relates to the Trustee.

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

          (g) The Trustee shall not be liable for interest or earnings on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by the law.

          (2) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel, or both, which shall conform to the provisions of Section 11.05.

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

          (7) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books records, and premises of the Company, personally or by agent or attorney at the sole cost of the

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

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

SECTION 7.03.Individual Rights of Trustee.

          The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may make loans to, accept deposits from, perform services for or otherwise deal with the either of the Company, or any Affiliate thereof, with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee, however, shall be subject to Sections 7.10 and 7.11.

SECTION 7.04.Trustee’s Disclaimer.

          The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes and it shall not be accountable for the Company’s use of the proceeds from the sale of Notes or any money paid to the Company pursuant to the terms of this Indenture and it shall not be responsible for any statement in the Notes or this Indenture other than its certificate of authentication, except that the Trustee

-64-

represents that it is duly authorized to execute and deliver this Indenture, authenticate the Notes and perform its obligations hereunder and that the statements made by it in any Statement of Eligibility and Qualification on Form T-1 to be supplied to the Company will be true and accurate subject to the qualifications set forth therein.

SECTION 7.05.Notice of Defaults.

          If a Default with respect to the Notes of any series occurs and is continuing and if it is known to the Trustee, the Trustee shall give to each Holder of such series a notice of the Default within 90 days after it occurs in the manner and to the extent provided in the TIA and otherwise as provided in this Indenture. Except in the case of a Default in payment of the principal of or interest on any Note (including payments pursuant to a redemption or repurchase of the Notes pursuant to the provisions of this Indenture), the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Holders.

SECTION 7.06.Reports by Trustee to Holders.

          If required by TIA § 313(a), within 60 days after June 15 of any year, commencing 2006, the Trustee shall mail to each Holder a brief report dated as of such date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA § 313(c) and comply with TIA § 313(d).

SECTION 7.07.Compensation and Indemnity.

          The Company shall pay to the Trustee and Agents from time to time such compensation for their services hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as shall be agreed upon in writing. The Company shall reimburse the Trustee and Agents upon request for all reasonable disbursements, expenses and advances incurred or made by them in connection with the Trustee’s duties under this Indenture, including the reasonable compensation, disbursements and expenses of the Trustee’s agents and external counsel, except any expense disbursement or advance as may be attributable to its willful misconduct or negligence.

          The Company shall fully indemnify each of the Trustee and any predecessor Trustee for, and hold each of them harmless against, any and all loss, damage, claim, liability or expense, including without limitation taxes (other than taxes based on the income of the Trustee or such Agent) and reasonable attorneys’ fees and expenses incurred by each of them in connection with the acceptance or performance of its duties under this Indenture including the reasonable costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder (including,

-65-

without limitation, settlement costs). The Trustee or Agent shall notify the Company in writing promptly of any claim of which a Responsible Officer of the Trustee has actual knowledge asserted against the Trustee or Agent for which it may seek indemnity;providedthat the failure by the Trustee or Agent to so notify the Company shall not relieve the Company of its obligations hereunder. In the event that a conflict of interest exists or potential harm to the Trustee’s business exists, the Trustee may have separate counsel, which counsel must be reasonably acceptable to the Company and the Company shall pay the reasonable fees and expenses of such counsel.

          Notwithstanding the foregoing, the Company need not reimburse the Trustee for any expense or indemnify it against any loss or liability to have been incurred by the Trustee through its own willful misconduct or negligence.

          To secure the payment obligations of the Company in this Section 7.07, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee and such money or property held in trust to pay principal of and interest on particular Notes.

SECTION 8.02.With Consent of Holders.

          (a) This Indenture as it applies to a series of Notes may be amended with the consent of the registered Holders of a majority in aggregate principal amount of the then outstanding Notes of such series (including consents obtained in connection with a tender offer or exchange offer for Notes of such series), and any past default or compliance with any provisions of this Indenture relating to a series of Notes may also be waived (except a default in the payment of principal, premium or interest and under Section 8.02(b) below) with the consent of the registered Holders of at least a majority in aggregate principal amount of the then outstanding Notes of such series.

     (ii) reduce the principal amount of, or any premium or interest rate on the Notes of such series;

          (d) After an amendment that requires the consent of the Holders of the affected Notes becomes effective, the Company shall mail to each registered Holder of the affected Notes at such Holder’s address appearing in the security register a notice briefly describing such amendment. However, the failure to give such notice to all Holders of such Notes, or any defect therein, shall not impair or affect the validity of the amendment.

          (e) Upon the written request of the Company accompanied by a board resolution authorizing the execution of any such supplemental indenture, and upon the receipt by the Trustee of evidence reasonably satisfactory to the Trustee of the consent of the Holders as aforesaid and upon receipt by the Trustee of the documents described in Section 8.06, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture, in which case the Trustee may, but shall not be obligated to, enter into such supplemental indenture.

-70-

SECTION 8.03.Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the 2010 Notes or the 2015 Notes, as the case may be, shall comply with the TIA as then in effect.

SECTION 8.04.Revocation and Effect of Consents.

          (a) After an amendment, supplement, waiver or other action becomes effective, a consent to it by a Holder of a Note is a continuing consent conclusive and binding upon such Holder and every subsequent Holder of the same Note or portion thereof, and of any Note issued upon the transfer thereof or in exchange therefor or in place thereof, even if notation of the consent is not made on any such Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

          (b) The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement, or waiver. If a record date is fixed, then, notwithstanding the preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only such Persons, shall be entitled to consent to such amendment, supplement, or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date.

In such case, the Trustee shall place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

SECTION 8.06.Trustee To Sign Amendments, etc.

          The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article Eight if the amendment, supplement or waiver does not affect the rights, duties, liabilities or immunities of the Trustee. If it does affect the rights, duties, liabilities or

-71-

immunities of the Trustee, the Trustee may, but need not, sign such amendment, supplement or waiver. In signing or refusing to sign such amendment, supplement or waiver the Trustee shall be entitled to receive and, subject to Section 7.01, shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating, in addition to the matters required by Section 11.04, that such amendment, supplement or waiver is authorized or permitted by this Indenture.

SECTION 9.01.Satisfaction and Discharge of Liability on Notes; Defeasance.

               (a) This Indenture will be discharged and will cease to be of further effect (except as to rights of registration of transfer or exchange of Notes which shall survive until all Notes have been canceled) as to all outstanding 2010 Notes or 2015 Notes, as the case may be, when either:

          (1) all the 2010 Notes or 2015 Notes, as the case may be, that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from this trust) have been delivered to the Trustee for cancellation; or

          (2) (a) all 2010 Notes or 2015 Notes, as the case may be, not delivered to the Trustee for cancellation otherwise (i) have become due and payable, (ii) will become due and payable, or may be called for redemption, within one year or (iii) have been called for redemption, and, in any case, the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds, in trust solely for the benefit of the Holders of such Notes, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) to pay and discharge the entire indebtedness (including all principal and accrued interest) on the Notes not theretofore delivered to the Trustee for cancellation, (b) the Company has paid all sums payable by it under this Indenture, and (c) the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the 2010 Notes or 2015 Notes, as the case may be, at maturity or on the date of redemption, as the case may be.

In addition, the Company shall deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent to satisfaction and discharge have been complied with.

-72-

               (b) Subject to Sections 9.01(c) and 9.02, the Company may, at its option and at any time, elect to have its obligations and the obligations of the Guarantors discharged with respect to the outstanding 2010 Notes or 2015 Notes, as the case may be (“Legal Defeasance”). Legal Defeasance means that the Company and the Guarantors shall be deemed to have paid and discharged the entire indebtedness represented by the Notes of the applicable series and the related Guarantees, and this Indenture shall cease to be of further effect as to all outstanding Notes of such series and the related Guarantees, except as to:

          (1) rights of Holders to receive payments in respect of the principal of and interest on the 2010 Notes or the 2015 Notes, as the case may be, when such payments are due from the trust funds referred to in Section 9.02,

          (4) this Article Nine, and

          (5) obligations under the TIA.

          In addition, the Company may, at its option and at any time, elect to have its obligations and the obligations of the Guarantors released with respect to Sections 4.06 through 4.12 under this Indenture with respect to either the 2010 Notes or the 2015 Notes (“Covenant Defeasance”), and thereafter any omission to comply with such obligations shall not constitute a Default with respect to such Notes. In the event Covenant Defeasance occurs, certain Events of Default (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events) will no longer apply. The Company may exercise its Legal Defeasance option regardless of whether it previously exercised Covenant Defeasance.

        (c) If the Company exercises its Legal Defeasance option, payment of the 2010 Notes or the 2015 Notes, as the case may be, may not be accelerated because of an Event of Default with respect thereto.

        (d) Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates.

-73-

        (e) Notwithstanding clauses (a) and (b) above, the Company’s obligations in Sections 2.04, 2.06, 2.07, 2.08, 7.07, 9.05 and 9.06 shall survive until such time as the 2010 Notes or the 2015 Notes, as the case may be, have been paid in full. Thereafter, the Company’s obligations in Sections 7.07, 9.05 and 9.06 shall survive.

SECTION 9.02.Conditions to Defeasance.

          To exercise the Legal Defeasance option or the Covenant Defeasance option in Section 9.01 with respect to the 2010 Notes or the 2015 Notes, as the case may be:

          (a) the Company must irrevocably deposit with the Trustee, as trust funds, in trust solely for the benefit of the Holders of the 2010 Notes or the 2015 Notes, as the case may be, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) in the opinion of a nationally recognized firm of independent public accountants selected by the Company, to pay the principal of and interest on the 2010 Notes or 2015 Notes, as the case may be, on the stated date for payment or on the redemption date of the principal or installment of principal of or interest on such Notes;

          (b) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States confirming that:

               (i) the Company has received from, or there has been published by the Internal Revenue Service, a ruling; or

               (ii) since the Issue Date, there has been a change in the applicable U.S. federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

          (c) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the Covenant Defeasance had not occurred;

-74-

          (d) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the borrowing of funds and the grant of any related liens to be applied to such deposit);

          (e) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a Default under this Indenture or a default under any other material agreement or instrument to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound (other than any such Default or default resulting solely from the borrowing of funds and the grant of any related liens to be applied to such deposit);

          (f) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by it with the intent of preferring the Holders over any other of its creditors or with the intent of defeating, hindering, delaying or defrauding any other of its creditors or others; and

          (g) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that the conditions provided for in, in the case of the Officers’ Certificate, clauses (a) through (f) and, in the case of the opinion of counsel, clauses (b) and/or (c) and (e) of this paragraph have been complied with.

          If the funds deposited with the Trustee to effect Covenant Defeasance are insufficient to pay the principal of and interest on the 2010 Notes or 2015 Notes, as the case may be, when due, then the Company’s obligations and the obligations of Guarantors under this Indenture will be revived and no such defeasance will be deemed to have occurred.

SECTION 9.03.Deposited Money and Government Obligations To Be Held in Trust; Other Miscellaneous Provisions.

          All money and Government Obligations (including the proceeds thereof) deposited with the Trustee pursuant to Section 9.02(a) in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent, to the Holders of such Notes, of all sums due and to become due thereon in respect of principal, premium, if any, and accrued interest, but such money need not be segregated from other funds except to the extent required by law.

-75-

          Anything in this Article Nine to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon a request of the Company any money or Government Obligations held by it as provided in Section 9.02(a) which, in the opinion of a nationally recognized firm of independent 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 an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 9.04.Reinstatement.

          If the Trustee or Paying Agent is unable to apply any money or Government Obligations in accordance with Section 9.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article Nine until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Obligations in accordance with Section 9.01;providedthat if the Company has made any payment of principal of, premium, if any, or accrued interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Obligations held by the Trustee or Paying Agent.

SECTION 9.05.Moneys Held by Paying Agent.

          In connection with the satisfaction and discharge of this Indenture, all moneys then held by any Paying Agent under the provisions of this Indenture shall, upon written demand of the Company, be paid to the Trustee, or if sufficient moneys have been deposited pursuant to Section 9.02(a), to the Company upon a request of the Company, and thereupon the Paying Agent shall be released from all further liability with respect to such moneys.

-76-

to Section 2.04, or cause to be published once a week for two successive weeks, in a newspaper published in the English language, customarily published each Business Day and of general circulation in the City of New York, New York, a notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such mailing or publication, any unclaimed balance of such moneys then remaining will be repaid to the Company.

Article Ten

GUARANTEES

     SECTION 10.01.Guarantees.

          (a) Each Guarantor, hereby jointly and severally, absolutely, unconditionally and irrevocably guarantees the Notes and obligations of the Company hereunder and thereunder, and guarantees to each Holder of a Note authenticated and delivered by the Trustee, and to the Trustee on behalf of such Holder, that (i) the principal of (and premium, if any) and interest on the Notes will be paid in full when due, whether at Stated Maturity, by acceleration or otherwise (including, without limitation, the amount that would become due but for the operation of any automatic stay provision of any Bankruptcy Law), together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same will be 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, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in Section 10.03 hereof.

          Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of Notes with respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

          (b) Each Guarantor hereby waives (to the extent permitted by law) the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first

-77-

against the Company or any other Person, protest, notice and all demands whatsoever and covenants that the Guarantee of such Guarantor shall not be discharged as to either the 2010 Notes or 2015 Notes, as the case may be, except by complete performance of the obligations contained in such Note, this Indenture and such Guarantee. Each Guarantor acknowledges that the Guarantee is a guarantee of payment and not of collection. Each of the Guarantors hereby agrees that, in the event of a default in payment of principal (or premium, if any) or interest on such Note, whether at its Stated Maturity, by acceleration, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce such Guarantor’s Guarantee without first proceeding against the Company or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor will pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

          (c) If any Holder or the Trustee is required by any court or otherwise to return to the Company or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or any Guarantor , any amount paid by any of them to the Trustee or such Holder, the Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) subject to this Article Ten, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six hereof for the purposes of the Guarantee of such Guarantor, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article Six hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Guarantee of such Guarantor.

          (d) Each Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes, whether as a “voidable preference”, “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to

-78-

the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

          (e) To evidence its Guarantee, each Guarantor hereby agrees that a Notation of Guarantee substantially in the form attached as Exhibit G hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered to the Trustee and that this Indenture or a supplemental indenture to this Indenture will be executed on behalf of such Guarantor by one of its Officers. Each Guarantor hereby agrees that its Guarantee will remain in full force and effect notwithstanding any failure to endorse on each Note a Notation of Guarantee. The delivery of any Note by the Trustee, after the authentication thereof hereunder, will be deemed to constitute due delivery of the Notation of Guarantee set forth in this Indenture by the Guarantors.

SECTION 10.02.Severability.

          In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 10.03.Limitation of Liability.

          Each Guarantor and by its acceptance hereof each Holder confirms that it is the intention of all such parties that the guarantee by each such Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law or the provisions of its local law relating to fraudulent transfer or conveyance.

[FORM OF REVERSE OF NOTE]

MYLAN LABORATORIES INC.

5.750% SENIOR NOTE DUE 2010

          1.Interest. MYLAN LABORATORIES INC., a Pennsylvania corporation, as issuer (the “Company”), promises to pay, until the principal hereof is paid or made available for payment, interest on the principal amount set forth on the face hereof at a rate of 5.750% per annum. Interest on the 5.750% Senior Notes due 2010 (the “Notes”) will accrue from and including the most recent date to which interest has been paid or, if no interest has been paid, from and including [           ] to but excluding the date on which interest is paid. Interest shall be payable in arrears on each February 15 and August 15, commencing on [          ]. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. The Company shall pay interest on overdue principal and on overdue interest (to the full extent permitted by law) at the rate borne by the Notes.

          2.Method of Payment. The Company will pay interest hereon (except defaulted interest) semiannually in arrears on February 15 and August 15, commencing on [           ]. The Company will pay interest to those persons who were holders of record on the February 1 and August 1, as the case may be, immediately preceding each interest payment date.

          Interest on the notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

          3.Paying Agent and Registrar. Initially, The Bank of New York (the “Trustee”) will act as a Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

          4.Indenture. The Company issued the Notes under an Indenture dated as of July 21, 2005 (the “Indenture”) between the Company and the Trustee. This is one of an issue of Notes of the Company issued, or to be issued, under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb), as amended from time to time. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of them. Capitalized and certain other terms used herein and not otherwise defined have the meanings set forth in the Indenture.

          5.Redemption of Notes with Net Cash Proceeds of Qualified Equity Offerings. Except as set forth in this paragraph 5 and paragraph 6 herein, the Notes may not be

A-1-4

redeemed prior to maturity. At any time or from time to time prior to August 15, 2008, the Company, at its option, may redeem up to 35% of the aggregate principal amount of the Notes issued under the Indenture with the net cash proceeds of one or more Qualified Equity Offerings at a redemption price equal to 105.750% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to the date of redemption;providedthat (1) at least 65% of the aggregate principal amount of Notes issued under the Indenture remains outstanding immediately after the occurrence of such redemption and (2) the redemption occurs within 120 days of the date of the closing of any such Qualified Equity Offering.

          “Qualified Equity Offering” means the issuance and sale of Qualified Capital Stock of the Company in a bona fide public or private offering.

          6.Make-Whole Redemption of Notes. Before August 15, 2010, the Company may also redeem all or any portion of the Notes upon not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium as of, and accrued and unpaid interest thereon, if any, to, the date of redemption (a “Make-Whole Redemption Date”).

          “Applicable Premium” means, with respect to any Note on any Make-Whole Redemption Date, the greater of (i) 1.0% of the principal amount of such Note and (ii) the excess of (A) the present value at such Make-Whole Redemption Date of (1) the principal amount of the Note at August 15, 2010, plus (2) all scheduled interest payments due on such Note from the Make-Whole Redemption Date through August 15, 2010, computed using a discount rate equal to the Treasury Rate at such Make-Whole Redemption Date, plus 50 basis points over (B) the principal amount of such Note.

          “Treasury Rate” means, with respect to any Make-Whole Redemption Date, the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15(519) that has become publicly available at least two business days prior to such Make-Whole Redemption Date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from such Make-Whole Redemption Date to August 15, 2010;providedthat if the period from such Make-Whole Redemption Date to August 15, 2010 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from such Make-Whole Redemption Date to August 15, 2010 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

          7.Redemption Procedures. The Trustee will select Notes called for redemption by lot on apro ratabasis or by such other means as are fair and reasonable (subject to procedures of the Depository);providedthat no Notes of $1,000 or less shall be redeemed

A-1-5

in part. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption pursuant to this paragraph 7 become due on the date fixed for redemption. On and after the Redemption Date, interest stops accruing on Notes or portions of them called for redemption.

          8.Notice of Redemption. Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed.

          9.Registration Rights. Pursuant to a registration rights agreement among the Company and the Initial Purchasers named therein (the “Registration Rights Agreement”), the Company will be obligated to consummate an exchange offer (the “Exchange Offer”) pursuant to which the Holder of this Note shall have the right to exchange this Note for Notes which have been registered under the Securities Act, in like principal amount and having substantially identical terms as the Notes.¹

          10.Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000.

          11.Persons Deemed Owners. The registered Holder of this Note may be treated as the owner of this Note for all purposes.

          12.Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an “abandoned property” law designates another Person.

          13.Amendment, Supplement, Waiver, Etc. The Company and the Trustee (if a party thereto) may, without the consent of the Holders of any outstanding Notes, amend, waive or supplement the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies, maintaining the qualification

¹ Only applicable to the Initial Notes issued on the Issue Date and any Additional Notes that are Restricted Notes.

A-1-6

Other amendments and modifications of the Indenture or the Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of the outstanding Notes, subject to certain exceptions requiring the consent of each of the Holders of the Notes to be affected.

          14.Purchase of Notes Upon a Change of Control. If a Change of Control occurs, each Holder of Notes will have the right to require that the Company purchase all or any part (in integral multiples of $1,000) of such Holder’s Notes pursuant to a Change of Control offer (a “Change of Control Offer”) except that the Company shall not be obligated to repurchase the Notes of any series pursuant to Section 4.12 of the Indenture in the event that the Company has exercised the right to optionally redeem all of the Notes. In the Change of Control Offer, the Company will offer to purchase all of the Notes, at a purchase price in cash in an amount equal to 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to the date of purchase (subject to the rights of Holders of record on relevant record dates to receive interest due on an Interest Payment Date).

          15.Successor Corporation. When a successor corporation assumes all the obligations of its predecessor under the Notes and the Indenture and the transaction complies with the terms of Article Five of the Indenture, the predecessor corporation will, except as provided in Article Five, be released from those obligations.

          16.Defaults and Remedies. Events of Default are set forth in the Indenture. Subject to certain limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Sections 6.01(8) and 6.01(9) of the Indenture with respect to the Company) occurs and is continuing, then, and either the Trustee, by notice in writing to the Company, or the Holders of not less than 25% of the principal amount of the Notes then outstanding, by notice in writing to the Company and the Trustee, and the Trustee at the request of such Holders shall, declare due and payable, if not already due and payable, the principal of and any accrued and unpaid interest on all of the Notes; and upon any such declaration all such amounts upon such Notes shall become and be immediately due and payable, anything in the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Sections 6.01(8) and 6.01(9) of the Indenture occurs with respect to the Company, then the principal of and any accrued and unpaid interest on all of the Notes shall be automatically due and immediately payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium, if any, or interest on the Notes or a default in the observance or performance

A-1-7

of any of the obligations of the Company under Article Five of the Indenture) if it determines that withholding notice is in their best interests.

          17.Trustee Dealings with Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee, in its individual or any other capacity, may become the owner or pledgee of the Notes and may make loans to, accept deposits from, and perform services for the Company or its Affiliates.

          18.No Recourse Against Others. No past, present or future director, manager, trustee, officer, employee, member, partner, agent or shareholder or Affiliate of the Company shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Notes.

          19.Discharge.

MYLAN LABORATORIES INC.

6.375% SENIOR NOTE DUE 2015

          1. Interest. MYLAN LABORATORIES INC., a Pennsylvania corporation, as issuer (the “Company”), promises to pay, until the principal hereof is paid or made available for payment, interest on the principal amount set forth on the face hereof at a rate of 6.375% per annum. Interest on the 6.375% Senior Notes due 2015 (the “Notes”) will accrue from and including the most recent date to which interest has been paid or, if no interest has been paid, from and including July 21, 2005 to but excluding the date on which interest is paid. Interest shall be payable in arrears on each February 15 and August 15, commencing [ ]. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. The Company shall pay interest on overdue principal and on overdue interest (to the full extent permitted by law) at the rate borne by the Notes.

          2. Method of Payment. The Company will pay interest hereon (except defaulted interest) semiannually in arrears on February 15 and August 15, commencing on [ ]. The Company will pay interest to those persons who were holders of record on the February 1 and August 1, as the case may be, immediately preceding each interest payment date.

          Interest on the notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

          3. Paying Agent and Registrar. Initially, The Bank of New York (the “Trustee”) will act as a Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

          4. Indenture. The Company issued the Notes under an Indenture dated as of July 21, 2005 (the “Indenture”) between the Company and the Trustee. This is one of an issue of Notes of the Company issued, or to be issued, under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb), as amended from time to time. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of them. Capitalized and certain other terms used herein and not otherwise defined have the meanings set forth in the Indenture.

          5. Optional Redemption. Except as set forth in this paragraph 5 and paragraphs 6 and 7 herein, the Notes may not be redeemed prior to maturity. At any time or from time to time on or after August 15, 2010, the Company, at its option, may redeem the Notes,

A-2-4

in whole or in part, at the redemption prices (expressed as percentages of principal amount) set forth below, together with accrued and unpaid interest thereon, if any, to the redemption date, if redeemed during the 12-month period beginning on August 15, of the years indicated:

	Optional
Year	Redemption Price
2010		103.188	%
2011		102.125	%
2012		101.063	%
2013 and thereafter		100.000	%

          6. Redemption of Notes with Net Cash Proceeds of Qualified Equity Offerings. At any time or from time to time prior to August 15, 2008, the Company, at its option, may redeem up to 35% of the aggregate principal amount of the Notes issued under the Indenture with the net cash proceeds of one or more Qualified Equity Offerings at a redemption price equal 106.375% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to the date of redemption;providedthat (1) at least 65% of the aggregate principal amount of Notes issued under the Indenture remains outstanding immediately after the occurrence of such redemption and (2) the redemption occurs within 120 days of the date of the closing of any such Qualified Equity Offering.

          “Qualified Equity Offering” means the issuance and sale of Qualified Capital Stock of the Company in a bona fide public or private offering.

          7. Make-Whole Redemption of Notes. Before August 15, 2010, the Company may also redeem all or any portion of the Notes upon not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium as of, and accrued and unpaid interest thereon, if any, to, the date of redemption (a “Make-Whole Redemption Date”).

          “Applicable Premium” means, with respect to any Note on any Make-Whole Redemption Date, the greater of (i) 1.0% of the principal amount of such Note and (ii) the excess of (A) the present value at such Make-Whole Redemption Date of (1) the redemption price of the Note at August 15, 2010 (exclusive of accrued interest), plus (2) all scheduled interest payments due on such Note from the Make-Whole Redemption Date through August 15, 2010, computed using a discount rate equal to the Treasury Rate at such Make-Whole Redemption Date, plus 50 basis points over (B) the principal amount of such Note.

          “Treasury Rate” means, with respect to any Make-Whole Redemption Date, the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15(519) that has become publicly available at least two business days prior to such Make-Whole Redemption Date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from such Make-Whole Redemption Date to August 15, 2010;providedthat if the period from such Make-Whole Redemption Date to August 15, 2010 is not equal to the constant maturity of a

A-2-5

United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from such Make-Whole Redemption Date to August 15, 2010 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

          8. Redemption Procedures. The Trustee will select Notes called for redemption by lot on apro ratabasis or by such other means as are fair and reasonable (subject to procedures of the Depository);providedthat no Notes of $1,000 or less shall be redeemed in part. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption pursuant to this paragraph 8 become due on the date fixed for redemption. On and after the Redemption Date, interest stops accruing on Notes or portions of them called for redemption.

          9. Notice of Redemption. Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed.

          10. Registration Rights. Pursuant to a registration rights agreement among the Company and the Initial Purchasers named therein (the “Registration Rights Agreement”), the Company will be obligated to consummate an exchange offer (the “Exchange Offer”) pursuant to which the Holder of this Note shall have the right to exchange this Note for Notes which have been registered under the Securities Act, in like principal amount and having substantially identical terms as the Notes.²

          11. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay to it any taxes and fees required by law or permitted by the Indenture.

          12. Persons Deemed Owners. The registered Holder of this Note may be treated as the owner of this Note for all purposes.

² Only applicable to the Initial Notes issued on the Issue Date and any Additional Notes that are Restricted Notes.

A-2-6

Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an “abandoned property” law designates another Person.

          14. Amendment, Supplement, Waiver, Etc. The Company and the Trustee (if a party thereto) may, without the consent of the Holders of any outstanding Notes, amend, waive or supplement the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies, maintaining the qualification of the Indenture under the Trust Indenture Act of 1939, as amended, providing for the assumption by a successor to the Company of its obligations under the Indenture and making any change that does not materially and adversely affect the rights of any Holder. Other amendments and modifications of the Indenture or the Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of the outstanding Notes, subject to certain exceptions requiring the consent of each of the Holders of the Notes to be affected.

          15. Purchase of Notes Upon a Change of Control. If a Change of Control occurs, each Holder of Notes will have the right to require that the Company purchase all or any part (in integral multiples of $1,000) of such Holder’s Notes pursuant to a Change of Control offer (a “Change of Control Offer”) except that the Company shall not be obligated to repurchase the Notes of any series pursuant to Section 4.12 of the Indenture in the event that the Company has exercised the right to optionally redeem all of the Notes. In the Change of Control Offer, the Company will offer to purchase all of the Notes, at a purchase price in cash in an amount equal to 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to the date of purchase (subject to the rights of Holders of record on relevant record dates to receive interest due on an Interest Payment Date).

          16. Successor Corporation. When a successor corporation assumes all the obligations of its predecessor under the Notes and the Indenture and the transaction complies with the terms of Article Five of the Indenture, the predecessor corporation will, except as provided in Article Five, be released from those obligations.

          17. Defaults and Remedies. Events of Default are set forth in the Indenture. Subject to certain limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Sections 6.01(8) and 6.01(9) of the Indenture with respect to the Company) occurs and is continuing, then, and either the Trustee, by notice in writing to the Company, or the Holders of not less than 25% of the principal amount of the Notes then outstanding, by notice in writing to the Company and the Trustee, and the Trustee at the request of such Holders shall, declare due and payable, if not already due and payable, the principal of and any accrued and unpaid interest on all of the Notes; and upon any such declaration all such amounts upon such Notes shall become and be immediately due and payable, anything in the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Sections 6.01(8) and 6.01(9) of the Indenture occurs with respect to the Company, then the principal of and any accrued and unpaid interest on all of the Notes shall be automatically due and immediately payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes except as provided in the Indenture.

A-2-7

The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium, if any, or interest on the Notes or a default in the observance or performance of any of the obligations of the Company under Article Five of the Indenture) if it determines that withholding notice is in their best interests.

          18. Trustee Dealings with Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee, in its individual or any other capacity may become the owner or pledgee of the Notes and may make loans to, accept deposits from, and perform services for the Company or its Affiliates.

          19. No Recourse Against Others. No past, present or future director, manager, trustee, officer, employee, member, partner, agent or shareholder or Affiliate of the Company shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Notes.

          20. Discharge. The Company’s obligations pursuant to the Indenture will be discharged, except for obligations pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment or cancellation of all the Notes or upon the irrevocable deposit with the Trustee of United States dollars or U.S. Government Obligations sufficient to pay when due principal of and interest on the Notes at maturity or redemption, as the case may be.

          21. Guarantees. The Company’s obligations under the Notes are fully, irrevocably and unconditionally guaranteed on a senior basis, to the extent set forth in the Indenture, by each of the Guarantors.

          22. Fall Away Event.

Sections 4.06, 4.07, 4.10 and 4.12 of the Indenture and the provisions set forth under Article Five of the Indenture will continue to be applicable in the event of the occurrence of a Fall Away Event.
