Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant

On October 16, 2012, Tenet Healthcare Corporation (“Tenet”) completed its offering of $500,000,000 in aggregate principal amount of 4.75% senior secured notes due 2020 (the “Secured Notes”) and $300,000,000 in aggregate principal amount of 6.75% senior unsecured notes due 2020 (the “Unsecured Notes” and, together with the Secured Notes, the “Notes”). The Notes were offered only to eligible purchasers through a private placement and have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws.

Secured Notes

Tenet will pay interest on the Secured Notes semi-annually, in arrears, on June 1 and December 1 of each year, commencing June 1, 2013, to holders of record on the immediately preceding May 15 and November 15. The Secured Notes will rank senior to Tenet’s existing and future subordinated indebtedness, be effectively senior to Tenet’s existing and future unsecured indebtedness and other liabilities to the extent of the value of the collateral securing the senior secured notes or guarantees thereon, and will rank pari passu with Tenet’s 6.25% senior secured notes due 2018, which were issued in November 2011 and April 2012, 10% senior secured notes due 2018, which were issued in March 2009, and 8.875% senior secured notes due 2019, which were issued in June 2009, and similarly will be guaranteed by and secured by a pledge of the capital stock and other ownership interests of certain of Tenet’s subsidiaries, and will be subordinated to Tenet’s obligations under its senior secured revolving credit facility, and any of its subsidiaries’ secured guarantees thereof, to the extent of the value of the collateral securing borrowings under such facility.

The Secured Notes were issued pursuant to the Base Indenture, as supplemented by a fifteenth supplemental indenture (the “Fifteenth Supplemental Indenture”) dated October 16, 2012, among Tenet, certain of its subsidiaries that will act as guarantors thereunder and The Bank of New York Mellon Trust Company, N.A., as successor trustee to The Bank of New York (the “Trustee”). The Fifteenth Supplemental Indenture contains covenants that, among other things, restrict Tenet’s ability and the ability of its subsidiaries: to incur liens; provide subsidiary guarantees; consummate asset sales; enter into sale and lease-back transactions; or consolidate, merge or sell all or substantially all of their assets, other than in certain transactions between one or more of Tenet’s wholly owned subsidiaries and Tenet. These restrictions, however, are subject to a number of important exceptions and qualifications. In particular, there are no restrictions on Tenet’s ability or the ability of its subsidiaries to incur additional indebtedness, make restricted payments, pay dividends or make distributions in respect of capital stock, purchase or redeem capital stock, enter into transactions with affiliates or make advances to, or invest in, other entities (including unaffiliated entities).

The Fifteenth Supplemental Indenture also provides that the Secured Notes may become subject to redemption under certain circumstances, including a change of control (as defined in the Fifteenth Supplemental Indenture) of Tenet. In addition, Tenet may, at its option, redeem the Secured Notes in whole or in part at any time at a redemption price equal to 100% of the principal amount of the Secured Notes being redeemed plus the applicable make-whole premium set forth in the Fifteenth Supplemental Indenture, together with accrued and unpaid interest.

In connection with the issuance of the Secured Notes, Tenet also entered into an Exchange and Registration Rights Agreement, dated as of October 16, 2012 (the “Secured Registration Rights Agreement”), with Barclays Capital Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc. and Wells Fargo Securities, LLC, as representatives of the initial purchasers. Pursuant to the Secured Registration Rights Agreement, Tenet has agreed to use commercially reasonable efforts to register the Secured Notes with the Securities and Exchange Commission if the Secured Notes have not become freely tradable (as defined in the agreement) on or before the 380th day following the date hereof.

The foregoing is a summary and is qualified by reference to the Fifteenth Supplemental Indenture and Secured Registration Rights Agreement, which are filed herewith as Exhibits 4.1 and 10.1, respectively, and are incorporated herein by reference.

Unsecured Notes

Tenet will pay interest on the Unsecured Notes semi-annually, in arrears, on February 1 and August 1 of each year, commencing February 1, 2013, to holders of record on the immediately preceding January 15 and July 15. The Unsecured Notes will be senior unsecured obligations of Tenet that will rank equally with Tenet’s other existing and future senior unsecured indebtedness, will rank senior to Tenet’s existing and future subordinated indebtedness and will be effectively subordinated to any existing and future secured indebtedness of Tenet to the extent of the value of the collateral securing such secured indebtedness.

The Unsecured Notes were issued pursuant to the Base Indenture, as supplemented by a sixteenth supplemental indenture (the “Sixteenth Supplemental Indenture”), dated October 16, 2012, between Tenet and the Trustee. The Sixteenth Supplemental Indenture contains covenants that, among other things, restrict Tenet’s ability and the ability of its subsidiaries: to incur liens; enter into sale and lease-back transactions; or consolidate, merge or sell all or substantially all of their assets, other than in certain transactions between one or more of Tenet’s wholly owned subsidiaries and Tenet. These restrictions, however, are subject to a number of important exceptions and qualifications. In particular, there are no restrictions on Tenet’s ability or the ability of its subsidiaries to incur additional indebtedness, make restricted payments, pay dividends or make distributions in respect of capital stock, purchase or redeem capital stock, enter into transactions with affiliates or make advances to, or invest in, other entities (including unaffiliated entities).

The Sixteenth Supplemental Indenture also provides that the Unsecured Notes may become subject to redemption under certain circumstances, including a change of control (as defined in the Sixteenth Supplemental Indenture) of Tenet. In addition, Tenet may, at its option, redeem the Unsecured Notes in whole or in part at any time at a redemption price equal to 100%

of the principal amount of the Unsecured Notes being redeemed plus the applicable make-whole premium set forth in the Sixteenth Supplemental Indenture, together with accrued and unpaid interest.

In connection with the issuance of the Unsecured Notes, Tenet also entered into an Exchange and Registration Rights Agreement, dated as of October 16, 2012 (the “Unsecured Registration Rights Agreement”), with Barclays Capital Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., Wells Fargo Securities, LLC, Goldman, Sachs & Co., Morgan Stanley & Co. LLC and Scotia Capital (USA) Inc. Pursuant to the Unsecured Registration Rights Agreement, Tenet has agreed to file an exchange offer registration statement for the Unsecured Notes with the Securities and Exchange Commission within 30 days after the date of the filing of its Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2012.

The foregoing is a summary and is qualified by reference to the Sixteenth Supplemental Indenture and Unsecured Registration Rights Agreement, which are filed herewith as Exhibits 4.2 and 10.2, respectively, and are incorporated herein by reference.

Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.5 hereof.

Section 2.2. Execution and Authentication

At least one Officer must sign the Notes for the Company by manual or facsimile signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

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

The Trustee will, upon receipt of a written order of the Company signed by an Officer (an “ Authentication Order ”), authenticate Notes for original issue that may be validly issued under the Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for

issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 306 of the Existing Indenture.

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Fifteenth Supplemental Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

Section 2.3. Registrar and Paying Agent

The Company will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“ Registrar ”) and an office or agency where Notes may be presented for payment (“ Paying Agent ”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not a party to the Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

The Company initially appoints The Depository Trust Company (“ DTC ”) to act as Depositary with respect to the Global Notes.

The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes and the Trustee hereby agrees so to initially act.

Section 2.4. Paying Agent to Hold Money in Trust

The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or Special Interest, if any, or interest on the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent will have no further liability for the money.

Section 3.2. Sinking Fund

The Company is not required to make mandatory sinking fund payments with respect to the Notes.

Section 3.3. Offer to Purchase by Application of Balance in Net Available Cash

In the event that, pursuant to Section 4.6 hereof, the Company is required to commence an offer to all Holders of Notes (and to holders of other First-Priority Stock Secured Debt) to purchase Notes (and such other First-Priority Stock Secured Debt) (an “ Asset Disposition Offer ”), it will follow the procedures specified below.

The Asset Disposition Offer shall be made to all Holders of Notes and all holders of other First-Priority Stock Secured Debt. The Asset Disposition Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “ Offer Period ”). No later than three Business Days after the termination of the Offer Period (the “ Purchase Date ”),

the Company will apply the Net Available Cash available for the Asset Disposition Offer (the “ Offer Amount ”) to the purchase of Notes and such other First-Priority Stock Secured Debt (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other First-Priority Stock Secured Debt tendered in response to the Asset Disposition Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

If the Purchase Date is on or after an interest record date and on or before the related Interest Payment Date, any accrued and unpaid interest and Special Interest, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Disposition Offer.

Upon the commencement of an Asset Disposition Offer, the Company will send, by first class mail, a notice to the Trustee and each of the Holders and each of the holders of other First-Priority Stock Secured Debt. The notice will contain all instructions and materials necessary to enable such holders to tender Notes and other First-Priority Stock Secured Debt pursuant to the Asset Disposition Offer. The notice, which will govern the terms of the Asset Disposition Offer, will state:

(1) that the Asset Disposition Offer is being made pursuant to this Section 3.3 and Section 4.6 hereof and the length of time the Asset Disposition Offer will remain open;

(2) the Offer Amount, the purchase price and the Purchase Date;

(3) that any Note not tendered or accepted for payment will continue to accrue interest;

(4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Disposition Offer will cease to accrue interest after the Purchase Date;

(5) that Holders electing to have a Note purchased pursuant to an Asset Disposition Offer may elect to have Notes purchased only in denominations of $2,000 and in integral multiples of $1,000 in excess thereof;

(6) that Holders electing to have Notes purchased pursuant to any Asset Disposition Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date;

(7) that holders of Notes and other First-Priority Stock Secured Debt will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of the Note or other First-Priority Stock Secured Debt the holder delivered for

purchase and a statement that such holder is withdrawing his election to have such Note or other First-Priority Stock Secured Debt purchased;

(8) that, if the aggregate principal amount of Notes and other First-Priority Stock Secured Debt surrendered by holders thereof exceeds the Offer Amount, the Company will select the Notes and other First-Priority Stock Secured Debt to be purchased on a pro rata basis based on the principal amount of Notes and such other First-Priority Stock Secured Debt surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess thereof, will be purchased); and

(9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes and other First-Priority Stock Secured Debt or portions thereof tendered pursuant to the Asset Disposition Offer, or if less than the Offer Amount has been tendered, all Notes and other First-Priority Stock Secured Debt tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.3. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Disposition Offer on the Purchase Date.

Other than as specifically provided in this Section 3.3, any purchase pursuant to this Section 3.3 shall be made pursuant to the provisions of Article Eleven of the Existing Indenture.

Section 4.1. Limitations on Liens

The Company covenants and agrees that neither it nor any of its Subsidiaries will issue, incur, create, assume or guarantee (collectively, “ incur ”) any Debt secured by Liens upon property or assets (including the Collateral), unless at the time of and after giving effect to the incurrence of such Debt, the aggregate amount of all such Secured Debt (including the aggregate principal amount of Notes outstanding at such time) shall not exceed the greater of (x) $3.2 billion and (y) the amount which would cause the Secured Debt Ratio to exceed 4.0 to 1.0;

If any such Secured Debt (other than Permitted Credit Agreement Debt) is secured by property or assets other than the Collateral, the Notes shall be secured equally and ratably with, or prior to, such Debt; provided that up to $75.0 million in principal amount of such Secured Debt (“ Other Secured Debt ”) is not subject to the equal and ratable security requirement in this sentence. To the extent that the Company or any of its Subsidiaries incurs any additional Debt permitted under this Section 4.1 (other than Other Secured Debt) that is secured by a Lien pari passu to the Lien securing the Notes or junior Lien on any property or assets, such Liens shall be subject to the Collateral Trust Agreement.

(6) Liens created in substitution of or as replacements for any Liens permitted by clauses (1) to (5) set forth above, provided that the property encumbered by any substitute or replacement Lien is similar in nature and value to the property encumbered by the Lien that is being replaced, as determined in good faith by an Officer of the Company; and

(7) Any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Lien referred to in the foregoing clauses (1) to (6) inclusive of any Debt secured thereby; provided that the principal amount of Debt secured thereby shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, and that such extension, renewal or

replacement Lien shall be limited to all or part of the same property that secured the Lien extended, renewed or replaced (plus improvements on such property).

Section 4.2. Limitations on Sale and Lease-Back Transactions

The Company covenants and agrees that neither it nor any of its Subsidiaries will enter into any Sale and Lease-Back Transaction with another Person, other than the Company or any Guarantor, unless:

(i) the Company or such Subsidiary could incur the Attributable Debt in respect of such Sale and Lease-Back Transaction secured by a Lien on the property to be leased in compliance with Section 4.1 hereof; and

(ii) the Company complies with Section 4.6 hereof.

Section 4.3. Limitations on Issuances of Guarantees by Subsidiaries

The foregoing restriction will not prohibit the issuance of Guarantees by any of the Company’s Subsidiaries in respect of Permitted Credit Agreement Debt.

wholly owned Subsidiaries) rights in respect of the Capital Stock of such Subsidiary, to execute and deliver to the Trustee a Note Guarantee pursuant to a supplemental indenture. The form of such Note Guarantee is attached as Exhibit E hereto.

Section 4.5. SEC Reports

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports.

All such reports shall be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each annual report on Form 10-K shall include a report on the consolidated financial statements of the Company and its Consolidated Subsidiaries by the Company’s independent registered public accounting firm.

Section 4.6. Asset Dispositions

The Company will not, and will not permit any of its Subsidiaries to, directly or indirectly, consummate any Asset Disposition unless:

(1) the Company or such Subsidiary receives consideration at the time of such Asset Disposition at least equal to the fair market value, as determined in good faith by the Company, of the shares and assets subject to such Asset Disposition;

(2) at least 75% of the consideration received in such Asset Disposition by the Company or such Subsidiary is in the form of cash or cash equivalents;

(3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company or such Subsidiary, as the case may be:

(A) to the extent the Company elects (or is required by the terms of any Debt), to prepay, repay, redeem or purchase Senior Debt of the Company or of a Guarantor or Debt of a Subsidiary that is not a Guarantor (in each case other than Debt owed to the Company or one of its Subsidiaries) within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; or

(B) to the extent the Company elects, to acquire Additional Assets within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; and

(4) to the extent of the balance of such Net Available Cash after application in accordance with clauses (3)(A) or (3)(B) above, such balance is applied by the Company or such Subsidiary, as the case may be, to make an Asset Disposition Offer to the Holders of the Notes (and to holders of other First-Priority Stock Secured Debt) to purchase Notes (and such other First-Priority Stock Secured Debt) pursuant to and subject to the conditions contained in this Section and Section 3.3 hereof;

provided , however , that in connection with any prepayment, repayment or purchase of Debt pursuant to clause (3)(A) or (4) above, the Company or such Subsidiary shall permanently retire such Debt and shall cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased; provided , further , however , that, in the case of clause (3)(B) above, a binding commitment shall be treated as a permitted application of the Net Available Cash from the date of such commitment so long as the Company or such Subsidiary enters into such commitment with the good faith expectation that such Net Available Cash will be applied to satisfy such commitment within 180 days of such commitment (an “ acceptable commitment ”); provided , further that if any acceptable commitment is later canceled or terminated for any reason before such Net Available Cash is applied, then such Net Available Cash shall be applied pursuant to clause (4) above.

Notwithstanding the foregoing provisions of the preceding paragraph, the Company and such Subsidiaries will not be required to apply any Net Available Cash in accordance with the preceding paragraph except to the extent that the aggregate Net Available Cash from all Asset Dispositions subject to the preceding paragraph which is not applied in accordance with the preceding paragraph exceeds $100.0 million. Pending application of Net Available Cash pursuant to this Section 4.6, such Net Available Cash may be used in any other manner not prohibited by the Indenture.

For purposes of this Section 4.6, the following are deemed to be cash or cash equivalents:

(1) the assumption or discharge of Debt or other liabilities of the Company or any Subsidiary and the release of the Company or such Subsidiary from all liability on such Debt or other liability in connection with such Asset Disposition;

(2) securities or other obligations received by the Company or any Subsidiary from the transferee that are converted by the Company or such Subsidiary into cash within 180 days of the Asset Disposition, to the extent of the cash received in that conversion; and

(3) Additional Assets.

In the event of an Asset Disposition that requires the purchase of Notes (and other First-Priority Stock Secured Debt), the Company will purchase Notes tendered pursuant to an Asset Disposition Offer by the Company for the Notes (and such other First-Priority Stock Secured Debt) at a purchase price of 100% of their principal amount (or, in the event such other First-Priority Stock Secured Debt was issued with significant original issue discount, 100% of the accreted value thereof), without premium, plus accrued but unpaid interest and Special Interest, if any (or, in respect of such other First-Priority Stock Secured Debt, such other price, not to

exceed 100%, as may be provided for by the terms of such other First-Priority Stock Secured Debt), in accordance with the procedures (including prorating in the event of oversubscription) set forth in Section 3.3 hereof. If there remains a balance of Net Available Cash after purchasing all securities tendered, then such balance may be used in any manner not prohibited by the Indenture. If the aggregate purchase price of the securities tendered exceeds the Net Available Cash allotted to their purchase, the Company will select the securities to be purchased on a pro rata basis but in round denominations, which in the case of the Notes will be denominations of $2,000 principal amount or any greater integral multiple of $1,000 in excess thereof. The Company shall not be required to make such an Asset Disposition Offer to purchase Notes (and other First-Priority Stock Secured Debt) pursuant to this Section 4.6 if the Net Available Cash available therefor is less than $100.0 million (which lesser amount shall be carried forward for purposes of determining whether such an Asset Disposition Offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). Upon completion of such an Asset Disposition Offer, Net Available Cash will be deemed to be reduced by the aggregate amount of such Asset Disposition Offer.

The Company will comply, to the extent applicable, with the requirements of Rule 14e-1 of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 4.6. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 3.3 hereof or this Section 4.6, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.3 hereof or this Section 4.6 by virtue of such compliance.

Section 4.7. Offer to Repurchase Upon Change of Control

(a) Upon the occurrence of a Change of Control, each Holder of Notes will have the right to require the Company to make an offer (a “ Change of Control Offer ”) to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Special Interest, if any, on the Notes repurchased, to the date of purchase (the “ Change of Control Payment ”).

Within 30 days following any Change of Control, the Company will mail a notice to each Holder and the Trustee describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 4.7 and that all Notes tendered will be accepted for payment;

(2) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date of such Change of Control (the “ Change of Control Payment Date ”);

(3) that any Note not tendered will continue to accrue interest;

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and

(7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.7, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.7 by virtue of such compliance.

(b) On the Change of Control Payment Date, the Company will:

(1) accept for payment all Notes or portions of Notes properly tendered and not validly withdrawn pursuant to the Change of Control Offer;

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

(3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

The Paying Agent will promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note issued for surrendered but unpurchased Notes will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Company will publicly announce the results of

the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c) Notwithstanding anything to the contrary in this Section 4.7, the Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.7 and purchases all Notes properly tendered and not validly withdrawn under the Change of Control Offer.

(d) Notwithstanding anything to contrary in this Section 4.7, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of the making of the Change of Control Offer.

(e) The Company may, with respect to the Notes, omit in any particular instance to comply with any term, provision or condition set forth in this Section 4.7, if before the time for such compliance the Holders of at least a majority in principal amount of the outstanding Notes shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. No supplemental indenture shall, without the consent of the Holder of each Outstanding Note affected thereby, modify any of the provisions of this Section 4.7(e), except to increase the percentage required to waive compliance by the Company of the covenants referenced here, provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section 4.7(e).

NOTE GUARANTEES

Section 9.1. Guarantee

(a) Subject to this Article Nine, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the Obligations of the Company hereunder or thereunder, that:

(1) the principal of, premium and Special Interest, if any, and interest on, the Notes will be promptly paid in full when due, whether at Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other Obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that their Obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, 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. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and the Indenture.

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any Obligations guaranteed hereby until payment in full of all Obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the Maturity of the Obligations guaranteed hereby may be accelerated as provided in Article Five of the Existing Indenture (as amended hereby) for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such Obligations as provided in Article Five of the Existing Indenture (as amended hereby), such Obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee.

Section 9.2. Limitation on Guarantor Liability

By its execution of this Fifteenth Supplemental Indenture, each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent

Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the Obligations of each Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the Obligations of such other Guarantor under this Article Nine, result in the Obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 9.3. Execution and Delivery of Note Guarantee

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 9.1 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

If an Officer whose signature is on this Fifteenth Supplemental Indenture or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Fifteenth Supplemental Indenture on behalf of the Guarantors.

Section 9.4. Guarantors May Consolidate, Etc., Only on Certain Terms

The Company will pay interest and Special Interest, if any, semi-annually in arrears on June 1 and December 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “ Interest Payment Date ”) . Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Event of Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be [ ], 20[ ]. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

(2) METHOD OF PAYMENT. The Company will pay interest on the Notes and Special Interest, if any, to the Persons who are registered Holders of Notes at the close of business on the May 15 or November 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date. The Notes will be payable as to principal, premium and Special Interest, if any, and interest at the office or agency of the Company maintained for such purpose within the City and State of New York, or, at the option of the Company, payment of interest and Special Interest, if any, may be made by check mailed to the Holders at their respective addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest, premium and Special Interest, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Until otherwise designated by the Company, the office or agency of the Company in New York will be the office of the Trustee maintained for such purpose.

(3) PAYING AGENT AND REGISTRAR. Initially, the corporate trust department of The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

A-2

(4) INDENTURE AND SECURITY DOCUMENTS. The Company issued the Notes under an Indenture, dated as of November 6, 2001, between the Company and The Bank of New York, as predecessor trustee to the Trustee, as supplemented by the Fifteenth Supplemental Indenture (the “ Fifteenth Supplemental Indenture ”), dated as of October 16, 2012 (as so supplemented, the “ Indenture ”), among the Company, the Guarantors and the Trustee. 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. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are secured Obligations of the Company. The Notes are secured by a pledge of the Collateral pursuant to the Stock Lien Security Documents referred to in the Indenture. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.

(5) OPTIONAL REDEMPTION .

The Company, at its option, may redeem the Notes, in whole or in part, at any time, at a Redemption Price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of the Redemption Date, plus accrued and unpaid interest thereon, and Special Interest, if any, to, but not including, the Redemption Date.

(6) MANDATORY REDEMPTION .

The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

(7) REPURCHASE AT THE OPTION OF HOLDER .

(b) In the event of an Asset Disposition that requires the purchase of Notes (and other First-Priority Stock Secured Debt), the Company will purchase Notes tendered pursuant to an offer (an “ Asset Disposition Offer ”) by the Company for the Notes (and such other First-Priority Stock Secured Debt) at a purchase price of 100% of their principal amount (or, in the event such other First-Priority Stock Secured Debt was issued with significant original issue discount, 100% of the accreted value thereof), without premium, plus accrued but unpaid interest and Special Interest, if any (or, in respect of such other First-Priority Stock Secured Debt, such other price, not to exceed 100%, as may be provided for by the terms of such other First-Priority Stock Secured Debt), in accordance with the procedures (including prorating in the event of oversubscription) set forth in Section 3.3 of the Fifteenth Supplemental Indenture. If there

A-3

remains a balance of Net Available Cash after purchasing all securities tendered, then such balance may be used in any manner not prohibited by the Indenture. If the aggregate purchase price of the securities tendered exceeds the Net Available Cash allotted to their purchase, the Company will select the securities to be purchased on a pro rata basis but in round denominations, which in the case of the Notes will be denominations of $2,000 principal amount or any greater integral multiple of $1,000 in excess thereof. Notwithstanding the foregoing, the Company shall not be required to make such an Asset Disposition Offer to purchase Notes (and other First-Priority Stock Secured Debt) if the Net Available Cash available therefor is less than $100.0 million (which lesser amount shall be carried forward for purposes of determining whether such an Asset Disposition Offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). Upon completion of such an Asset Disposition Offer, Net Available Cash will be deemed to be reduced by the aggregate amount of such Asset Disposition Offer. Holders of Notes that are the subject of an offer to purchase will receive an Asset Disposition Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

(8) NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed.

(9) DENOMINATIONS , TRANSFER , EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

(10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

(11) AMENDMENT , SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single class, and any existing Event or Default or compliance with any provision of the Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single class.

A-4

Without the consent of any Holder of a Note, the Indenture or the Notes or the Note Guarantees may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of the Notes and Note Guarantees in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder or to comply with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act.

(12) EVENTS OF DEFAULT AND REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest on, or Special Interest, if any, with respect to the Notes; (ii) default in the payment when due of the principal of, or premium, if any, on, the Notes when the same becomes due and payable at Maturity; (iii) failure by the Company for 30 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes including Additional Notes, if any, then outstanding to comply with Section 4.6 or 4.7 of the Fifteenth Supplemental Indenture; (iv) failure by the Company or any Guarantor for 90 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes including Additional Notes, if any, then outstanding to comply with the covenants or warranties in the Indenture; (v) default under certain other agreements relating to Debt of the Company or any Guarantor which default results in the acceleration of such Debt prior to its express maturity; (vi) certain events of bankruptcy or insolvency with respect to the Company or any Guarantor that is a Significant Subsidiary or any group of Guarantors that, taken together, would constitute a Significant Subsidiary; (vii) with respect to Collateral having a fair market value in excess of $25.0 million, the security interest created under the Pledge Agreement, any other Stock Lien Security Document or the Indenture is held in any judicial proceeding to be unenforceable or invalid or the security interest in the Pledge Agreement ceases for any reason to be in full force and effect for any reason other than in accordance with the terms of the Indenture and the Pledge Agreement and any other Stock Lien Security Document or the Company or any Subsidiary asserts, in any pleading in a judicial proceeding, that any security interest created under the Pledge Agreement, any other Stock Lien Security Document or the Indenture is invalid or unenforceable; and (viii) except as permitted by the Indenture or the Note Guarantees, any Note Guarantee of any Guarantor that is a Significant Subsidiary or any group of Guarantors that, taken together, would constitute a Significant Subsidiary ceases for any reason to be in full force and effect and enforceable or the Company or any Guarantor denies or disaffirms the Guarantor’s obligations under such Guarantor’s Note Guarantee. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate 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 of the Notes notice of any continuing Event of Default (except an Event of Default relating to the payment of principal or interest or premium or Special Interest, if any) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the

A-5

Notes, rescind an acceleration or waive any existing Event of Default and its consequences under the Indenture except a continuing Event of Default in the payment of interest or premium or Special Interest, if any, on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required, upon becoming aware of any Event of Default, to deliver to the Trustee a statement specifying such Event of Default.

(13) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

(14) NO RECOURSE AGAINST OTHERS. A director, officer, employee, incorporator or stockholder of the Company or any of the Guarantors, as such, will not have any liability for any obligations of the Company or the Guarantors under the Notes, the Note Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

(15) AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

(16) ABBREVIATIONS.

WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture, dated as of November 6, 2001 (the “ Base Indenture ”), between the Company and The Bank of New York, as predecessor trustee to the Trustee, as supplemented by the Fifteenth Supplemental Indenture, dated as of October 16, 2012 (the “ Fifteenth Supplemental Indenture ”), among the Company, the Guarantors party thereto and the Trustee (as so supplemented, the “ Indenture ”), providing for the issuance of 4.75% Senior Secured Notes due 2020 (the “ Notes ”);
