Indenture; (ii) the Holders of not less than 25% in aggregate principal amount of the Outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under the Indenture; (iii) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request; (iv) the Trustee has failed to institute any such proceeding for 60 days after its receipt of such notice, request and offer of indemnity; and (v) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Outstanding Notes, it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of the Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under the Indenture, except in the manner provided in the Indenture and for the equal and ratable benefit of all of such Holders.

The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal of, and premium, if any, or interest hereon, on or after the respective due dates expressed herein.

6. Amendment, Supplement and Waiver . The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes under the Indenture at any time by the Company and the Trustee with the written consent of the Holders of at least a majority in aggregate principal amount of the Outstanding Notes. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Outstanding Notes, on behalf of the Holders of all the Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note or such other Note. Certain modifications or amendments to the Indenture require the consent of the Holder of each Outstanding Note affected.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair (without the consent of the Holder hereof) the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed.

7. Registration and Transfer . As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registerable on the Security Register. Upon surrender for registration of transfer of this Note at the office or agency of the Company in a Place of Payment, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of like tenor and principal amount. As provided in the Indenture and subject to certain limitations therein set forth, at the option of the Holder, this Note may be exchanged for one or more new Notes of any authorized denominations and of like tenor and principal

amount, upon surrender of this Note at such office or agency. Upon such surrender by the Holder, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of like tenor and principal amount. Every Note presented or surrendered for registration of transfer or for exchange shall be duly endorsed (if so required by the Company or the Trustee), or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or such Holder’s attorney duly authorized in writing. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

Prior to due presentment of this Note for registration of transfer, the Company, the Guarantors, the Trustee and any agent of the Company, a Guarantor or the Trustee may treat the Person in whose name such Note is registered as the owner thereof for all purposes, whether or not such Note be overdue, and neither the Company, the Guarantors, the Trustee nor any agent of the Company, a Guarantor or the Trustee shall be affected by notice to the contrary.

8. Guarantee . As expressly set forth in the Base Indenture, payment of this Note is jointly and severally and fully and unconditionally guaranteed by the Guarantors that have become and continue to be Guarantors pursuant to the Indenture. Guarantors may be released from their obligations under the Indenture and their Guarantees under the circumstances specified in the Base Indenture.

9. Governing Law . THE INDENTURE, THIS SECURITY AND THE GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

The following abbreviations, when used in the inscription of the face of this Note, shall be construed as though they were written out in full according to applicable laws or regulations:

“ Event of Default ” means, wherever used herein with respect to the Notes, any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be 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):

(2) the Company’s failure to pay the Repurchase Price when due in connection with a Change of Control Repurchase Event.

Section 512 of the Base Indenture shall not apply to the Notes, and, with respect to the Notes, any reference to Section 512 in the Base Indenture shall instead be deemed to refer to this Section 4.2.

The Holders of not less than a majority in aggregate principal amount of the Outstanding Notes may on behalf of the Holders of all the Notes waive any past Default hereunder with respect to the Notes and its consequences, except a default

(1) in the payment of the principal of or premium, if any, or interest on any Note or the Repurchase Price in connection with a Change of Control Repurchase Event; or

(2) in respect of a covenant or provision hereof or of the Base Indenture which under Article VII hereof or under Article IX of the Base Indenture cannot be modified or amended without the consent of the Holder of each Outstanding Note affected.

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

The Notes will be redeemable in whole or in part, at the Company’s option at any time and from time to time, at a Redemption Price equal to the greater of (i) 100% of the aggregate principal amount of any Notes being redeemed and (ii) the sum of the present values

of the remaining scheduled payments of principal and interest on any Notes being redeemed (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points, plus in each case accrued and unpaid interest thereon to, but excluding, the Redemption Date.

The Credit Parties shall not, and shall not cause or permit any of their respective Subsidiaries to, create, assume, incur or guarantee any indebtedness for money borrowed that is secured by a pledge, mortgage, lien or other encumbrance (other than Permitted Liens) on any voting stock or profit participating equity interests of their respective Subsidiaries (to the extent of their ownership of such voting stock or profit participating equity interests) or any entity that succeeds (whether by merger, consolidation, sale of assets or otherwise) to all or any substantial part of the business of any of such Subsidiaries, without providing that the Notes (together with, if the Credit Parties shall so determine, any other indebtedness of, or guarantee by, the Credit Parties ranking equally with the Notes and existing as of the closing of the offering of the Notes or thereafter created) will be secured equally and ratably with or prior to all other indebtedness secured by such pledge, mortgage, lien or other encumbrance on the voting stock or profit participating equity interests of any such entities. This Section 6.1 shall not limit the ability of the Credit Parties or their Subsidiaries to incur indebtedness or other obligations secured by liens on assets other than the voting stock or profit participating equity interests of the Credit Parties and their respective Subsidiaries.

SECTION 6.2. Obligation to Offer to Repurchase Upon a Change of Control Repurchase Event .

(1) If a Change of Control Repurchase Event occurs, unless the Company has exercised its option to redeem the Notes pursuant to Article V, the Company shall make an offer to each Holder of Notes to repurchase all or any part of that Holder’s Notes (the “ Change of Control Offer ”) at a repurchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but excluding, the date of purchase (the “ Repurchase Price ”).

(2) In connection with any Change of Control related to a Change of Control Repurchase Event and any particular reduction in the rating on the Notes, the Company shall request from the Rating Agencies each such Rating Agency’s written confirmation that such reduction in the rating on the Notes was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of any Below Investment Grade Rating Event). The Company shall promptly certify to the Trustee as to whether or not such confirmation has been received or denied.

(3) Within 30 days following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Company shall give notice to each Holder of Notes, with a written copy to the Trustee. Such notice shall state:

(i) a description of the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event;

(ii) that the Change of Control Offer is being made pursuant to this Section 6.2;

(iii) the Repurchase Price and the date on which the Repurchase Price will be paid, which date shall be a Business Day that is no earlier than 30 days and no later than 60 days from the date such notice is mailed, other than as may be required by law (the “ Repurchase Price Payment Date ”); and

(iv) if the notice is given prior to the date of consummation of the Change of Control, a statement that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice.

(4) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act of 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 as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

(5) On the Repurchase Price Payment Date, the Company shall, to the extent lawful:

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

(ii) deposit with the Paying Agent an amount equal to the Repurchase Price in respect of all Notes or portions of Notes properly tendered; and

(iii) 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.

The Paying Agent shall promptly mail to each Holder of Notes properly tendered the Repurchase Price for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder of Notes properly tendered a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note will be in a principal amount of $2,000 or any integral multiple of $1,000 in excess thereof.

(6) Notwithstanding the foregoing, the Company shall not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if (i) a third party makes such an offer in respect of the Notes in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all the Notes properly tendered and not withdrawn under its offer or (ii) the Company has given written notice of a redemption as provided under Section 1104 of the Base Indenture; provided that the Company has not failed to pay the Redemption Price on the Redemption Date.

Section 704 of the Base Indenture shall apply to the reports, information, and documents delivered under this Section 6.3.

(1) For so long as Partnership is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall provide (or cause its Affiliates to provide) to the Trustee, unless available on the Commission’s Electronic Data Gathering, Analysis and Retrieval System (or successor system), within 15 days after the Partnership files the same with the Commission, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) which the Partnership may file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act. The Trustee may conclusively presume, and shall incur no liability in such presumption, that the Partnership has not filed any such reports, information, documents and other reports with the Commission that are not available on the Commission’s Electronic Data Gathering, Analysis and Retrieval System (or successor system) unless and until it shall have received written notice from the Company to the contrary.

(2) For so long as any of the Notes remain Outstanding, the Company shall, or shall cause its Affiliates to, furnish to the Holders of the Notes and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act and, unless available on the Commission’s Electronic Data Gathering, Analysis and Retrieval System (or successor system), such information for the Partnership (as if such rule applied to it); provided , however , that if any time the Partnership no longer directly or indirectly controls the Credit Parties or guarantees the Notes, such information shall be provided for either (i) the Credit Parties on a combined and consolidated basis and taken as a whole or (ii) any Person that directly or indirectly controls the Credit Parties and guarantees the Notes (in each case, as if such rule applied to such Persons). The Company shall, or shall cause its Affiliates to, make the above information and reports available to securities analysts and prospective investors upon request.

For the purposes of the Base Indenture and this Second Supplemental Indenture, no amendment to cure any ambiguity, defect or inconsistency in this Second Supplemental Indenture, the Base Indenture or the Notes made solely to conform this Second Supplemental Indenture, the Base Indenture or the Notes to the Description of the Notes contained in the Company’s offering memorandum dated September 15, 2010, to the extent that such provision in the Description of the Notes was intended to be a verbatim recitation of a provision of this Second Supplemental Indenture, the Base Indenture or the Notes, shall be deemed to adversely affect the interests of the Holders of any Notes.

Section 902 of the Base Indenture shall not apply to the Notes, and, with respect to the Notes, any reference to Section 902 in the Base Indenture shall instead be deemed to refer to this Section 7.2.

With the consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes affected by such supplemental indenture (including consents obtained in connection with a tender offer or exchange for the Notes), by Act of said Holders delivered to the Company, the Guarantors and the Trustee, the Company, the Guarantors and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the Holders of such Notes under the Indenture; provided , however , no such supplemental indenture shall, without the consent of the Holder of each Outstanding Note affected thereby:

(1) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Note;

(2) reduce the principal amount of any Note which would be due and payable at or upon a declaration of acceleration of the maturity thereof pursuant to Section 502 and 503 of the Base Indenture, or reduce the rate of or extend the time of payment of interest on any Note;

(3) reduce the Repurchase Price in connection with a Change of Control Repurchase Event;

(4) reduce any premium payable upon the redemption of or change the date on which any Note may or must be redeemed;

(5) change the coin or currency in which the principal of or premium, if any, or interest on any Note is payable;

(6) impair the right of any Holder to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date);

(7) reduce the percentage in principal amount of the Outstanding Notes the consent of whose Holders is required for modification or amendment of this Second Supplemental Indenture or the Base Indenture or the consent of whose Holders is required for any waiver (of compliance with certain provisions of the Base Indenture or this Second Supplemental Indenture or certain defaults thereunder and hereunder and their consequences) provided for in the Base Indenture and this Second Supplemental Indenture

(8) modify any of the provisions of this Section 7.2 or Section 512 or Section 1005 of the Base Indenture, except to increase any such percentage or to provide that certain other provisions of this Second Supplemental Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Note affected thereby; provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in Section 902 and Section 1005 of the Base Indenture, or the deletion of this proviso, in accordance with the requirements of Sections 611 and 901(7) of the Base Indenture;

(9) subordinate the Notes or any Guarantee of a Guarantor in respect thereof to any other obligation of the Company or such Guarantor;

(10) modify the terms of any Guarantee in a manner adverse to the Holders of the Notes; or

It shall not be necessary for any Act of Holders under this Section 7.2 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

In addition, the Holders of at least a majority in aggregate principal amount of the Outstanding Notes may, on behalf of the Holders of all Notes, waive compliance with the Credit Parties’ covenants described under Sections 6.1, 6.2 and 6.3 of this Second Supplemental Indenture and Article VIII of the Base Indenture.

Section 1303 of the Base Indenture shall not apply to the Notes, and, with respect to the Notes, any reference to Section 1303 in the Base Indenture shall instead be deemed to refer to this Section 8.1.

Upon the Company’s exercise of its option, if any, to have Section 1303 of the Base Indenture applied to the Notes, or if Section 1303 of the Base Indenture shall otherwise apply to the Notes, (1) the Company and the Guarantors shall be released from their respective obligations and any covenants provided pursuant to Articles VI of this Second Supplemental Indenture and Section 301(18), Section 801, Section 901(1) or Section 901(12) and Article XIV of the Base Indenture for the benefit of the Holders of such Notes and (2) the occurrence of any event specified in Section 501(4) and Section 501(8) of the Base Indenture shall be deemed not to be or result in an Event of Default, in each case with respect to such Notes and the related Guarantees as provided in Section 1303 of the Base Indenture on and after the date the conditions set forth in Section 1304 of the Base Indenture are satisfied (hereinafter called “ Covenant Defeasance ”). For this purpose, such Covenant Defeasance means that, with respect to such Notes and Guarantees, each of the Company and the Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document, but the remainder of the Base Indenture, this Second Supplemental Indenture and such Notes and Guarantees shall be unaffected thereby.

This Second Supplemental Indenture is executed and shall be construed as an indenture supplemental to the Base Indenture and, as provided in the Base Indenture, this Second Supplemental Indenture forms a part thereof.

The recitals contained herein and in the Notes, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company and the Guarantors, as the case may be, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Second Supplemental Indenture or of the Securities or the Guarantees. The Trustee shall not be accountable for the use or application by the Company of the Notes or the proceeds thereof.

In case any provision in this Second Supplemental Indenture or in the Notes 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.

All covenants and agreements in this Second Supplemental Indenture by the Company and the Guarantors shall bind their respective successors and assigns, whether so expressed or not. All agreements of the Trustee in this Second Supplemental Indenture shall bind its successors and assigns, whether so expressed or not.

This Second Supplemental Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

This Second Supplemental Indenture shall be governed by, and construed in accordance with, the law of the State of New York.

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