While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than an Issuer or one of its Subsidiaries) will have no further liability for the money. If an Issuer or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuers, the Trustee will serve as Paying Agent for the Notes.

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Issuers will furnish to the Trustee at least seven 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 of Notes and the Issuers shall otherwise comply with TIA §312(a).

(f) Exchange Offer. Upon the occurrence of the Exchange Offer in accordance with the Registration Rights Agreement, the Issuers will issue and, upon receipt of an Authentication Order in accordance with Section 2.02, the Trustee will authenticate:

Concurrently with the issuance of such Notes, the Trustee will cause the aggregate principal amount of the applicable Restricted Global Notes to be reduced accordingly, and the Issuers will execute and the Trustee will authenticate and deliver to the Persons designated by the Holders of Definitive Notes so accepted Unrestricted Definitive Notes in the appropriate principal amount.

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (1) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.06 OF THE INDENTURE, (2) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE INDENTURE, (3) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND (4) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF COMPRESSCO PARTNERS, L.P.

OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.”

(3) Regulation S Temporary Global Note Legend. The Regulation S Temporary Global Note will bear a legend in substantially the following form:

“THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND THE CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR DEFINITIVE NOTES, ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN). NEITHER THE HOLDER NOR THE BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL NOTE SHALL BE ENTITLED TO RECEIVE PAYMENT OF INTEREST HEREON.”

(h) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.11. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(1) To permit registrations of transfers and exchanges, the Issuers will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 or at the Registrar’s request.

(2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuers may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Section 2.10, Section 3.06, Section 4.10, Section 4.14 and Section 9.05).

(3) The Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

(4) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Issuers, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 and ending at the close of business on the day of selection;

(B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

(C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

(6) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuers may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Issuers shall be affected by notice to the contrary.

(7) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02.

(8) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by electronic transmission.

If any mutilated Note is surrendered to the Trustee or the Issuers and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuers will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuers, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuers to protect the Issuers, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuers may charge for their expenses in replacing a Note.

Every replacement Note is an additional obligation of the Issuers and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09, a Note does not cease to be outstanding because the Issuers or an Affiliate of either Issuer holds the Note; provided, however that Notes held by either of the Issuers or a Subsidiary of either Issuer shall be deemed to be not outstanding for purposes of Section 3.07(a).

If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

If the principal amount of any Note is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than an Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by any Issuer or Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with any Issuer or Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee actually knows are so owned will be so disregarded.

Until certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuers consider appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

The Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirements of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Issuers upon written request. The Issuers may not issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation.

If the Issuers default in a payment of interest on the Notes, they will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01. The Issuers will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuers will fix or cause to be fixed each such special record date and payment date, provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) will send or cause to be sent to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07, it must furnish to the Trustee, at least 30 days but not more than 60 days before a redemption date, an Officers’ Certificate setting forth:

If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee will select Notes for redemption or purchase on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 2, based on the method of the Depositary that most nearly approximates a pro rata selection), unless otherwise required by law or applicable stock exchange or depository requirements.

In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase.

The Trustee will promptly notify the Issuers in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

Subject to the provisions of Section 4.10 and Section 4.14, at least 30 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail (or, in the case of Notes in global form, pursuant to the Applicable Procedures of the Depositary), a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent 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 and discharge of this Indenture pursuant to Article 8 or Article 11.

(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note;

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(6) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;

(7) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed;

(8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes and

(9) if such redemption or notice is subject to satisfaction of one or more conditions precedent, that, in the Issuers’ discretion, the redemption date may be delayed until such time as

any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed.

At the Issuers’ request, the Trustee will give the notice of redemption in the Issuers’ names and at their expense; provided, however, that the Issuers have delivered to the Trustee, at least 45 days prior to the redemption date (unless a shorter time is acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Notwithstanding any provision hereof to the contrary, the notice of redemption with respect to a redemption pursuant to Section 3.07(b) need not set forth the Make-Whole Price but only the manner of calculation thereof. The Company will notify the Trustee in writing of the Make-Whole Price with respect to any redemption promptly after the calculation (in the case of Definitive Notes, at least two days prior to the redemption date), and the Trustee shall not be responsible for such calculation.

Once notice of redemption is sent in accordance with Section 3.03, Notes called for redemption become due on the date fixed for redemption, unless the redemption is subject to a condition precedent that is not satisfied or waived. Any redemption or notice of redemption may, at the Issuers’ discretion, be subject to one or more conditions precedent and, in the case of a redemption pursuant to Section 3.07(a), be given prior to and conditioned on the completion of the related Equity Offering.

At least one Business Day prior to the redemption or purchase date, the Issuers will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of, accrued interest and Liquidated Damages, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of, accrued interest and Liquidated Damages, if any, on all Notes to be redeemed or purchased.

If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01.

Upon surrender of a Note that is redeemed or purchased in part, the Issuers will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

(a) Prior to August 15, 2017, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes outstanding under this Indenture (which may include Additional Notes) with an amount of cash not greater than the amount of the net cash proceeds from one or more Equity Offerings at a redemption price equal to 107.250% of the principal amount thereof, plus accrued and unpaid interest and Liquidated Damages, if any, on the Notes to be redeemed to the redemption date (subject to the rights of Holders of record on the relevant record date to receive interest and Liquidated Damages, if any, due on the relevant interest payment date); provided that

(1) at least 65% of the aggregate principal amount of the Notes issued on the Issue Date (excluding Notes held by the Company and its Subsidiaries) remains outstanding after each such redemption; and

(2) the redemption occurs within 180 days after the closing of such Equity Offering.

(b) At any time or from time to time prior to August 15, 2017, the Company may also redeem all or a part of the Notes, at a redemption price equal to the Make-Whole Price, subject to the rights of Holders of Notes on the relevant record date to receive interest and Liquidated Damages, if any, due on the relevant interest payment date.

(c) In the event that Holders of not less than 90% in aggregate principal amount of the outstanding Notes accept a Change of Control Offer or Alternate Offer and the Company (or any third party making such Change of Control Offer in lieu of the Company as set forth in Section 4.14(c)) purchases all of the Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer or Alternate Offer described in Section 4.14, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest and Liquidated Damages, if any, on the Notes that remain outstanding, to the date of redemption (subject to the rights of Holders of record on the relevant record date to receive interest and Liquidated Damages, if any, due on an interest payment date that is on or prior to the redemption date).

(d) Except as provided in the preceding paragraphs (a), (b) and (c), the Notes will not be redeemable at the Company’s option prior to August 15, 2017.

(e) On and after August 15, 2017, the Company may redeem all or a part of the Notes, from time to time, upon not less than 30 nor more than 60 days’ notice, at the following redemption prices (expressed as a percentage of the principal amount) plus accrued and unpaid interest and Liquidated Damages, if any, on the Notes to be redeemed to the applicable redemption date (subject to the rights of Holders of record on the relevant record date to receive interest and Liquidated Damages, if any, due on the relevant interest payment date), if redeemed during the twelve-month period beginning on August 15 of the years indicated below:

(f) Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

(g) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through Section 3.06.

The Issuers will pay or cause to be paid the principal of, premium on, if any, interest and Liquidated Damages, if any, on, the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, interest and Liquidated Damages, if any, will be considered paid on the date due if the Paying Agent, if other than the Issuers or a Subsidiary thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by the Issuers in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest, if any, then due. The Issuers will pay all Liquidated Damages, if any, in the same manner on the dates and in the amounts set forth in the Registration Rights Agreement.

The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the then applicable interest rate on the Notes to the extent lawful. The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Liquidated Damages, if any (without regard to any applicable grace period) at the same rate to the extent lawful.

The Issuers will maintain in the Borough of Manhattan, The City of New York, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Issuers will give prompt written notice to the Trustee of any change in the location of such office or agency. If at any time the Issuers fail to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

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

The Issuers hereby designate the Corporate Trust Office of the Trustee as one such office or agency of the Issuers in accordance with Section 2.03.

(a) Regardless of whether required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Company will file with the SEC (unless the SEC will not accept such a filing) within the time periods specified in the SEC’s rules and regulations, and upon request, the Company will furnish (without exhibits) to the Trustee for delivery to the Holders of Notes:

(1) all quarterly and annual reports that would be required to be contained in a filing with the SEC on Forms 10-Q and
10-K if the Company were required to file such forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report thereon by the Company’s certified independent accountants; and

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

(b) The Company will be deemed to have furnished such reports and information described above in Section 4.03(a) to the Holders of Notes (and the Trustee shall be deemed to have delivered such reports and information to the Holders of Notes) if the Company has filed such reports or information, respectively, with the SEC using the EDGAR filing system (or any successor filing system of the SEC) or, if the SEC will not accept such reports or information, if the Company has posted such reports or information, respectively, on its website, and such reports or information, respectively, are available to Holders of Notes through internet access.

(c) For the avoidance of doubt, (i) such information will not be required to contain the separate financial information for Guarantors as contemplated by Rule 3-10 of Regulation S-X or any financial statements of unconsolidated subsidiaries or 50% or less owned Persons as contemplated by Rule 3-09 of Regulation S-X or any schedules required by Regulation S-X, or in each case any successor provisions, and (ii) such information shall not be required to comply with Regulation G under the Exchange Act or Item 10(e) of Regulation S-K with respect to any non-GAAP financial measures contained therein.

(d) Except as provided above, all such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports.

(e) If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then, to the extent material, the quarterly and annual financial information required by Section 4.03(a) above will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of its Unrestricted Subsidiaries.

(f) Any and all Defaults or Events of Default arising from a failure to furnish in a timely manner any financial information required by this Section 4.03 shall be deemed cured (and the Company shall be deemed to be in compliance with this Section 4.03) upon furnishing such financial information as contemplated by this Section 4.03 (but without regard to the date on which such financial statement or report is so furnished); provided that such cure shall not otherwise affect the rights of the Holders under the provisions of Article 6 if the principal of, premium, if any, on, and interest, if any, on, the Notes have been accelerated in accordance with the terms of this Indenture and such acceleration has not been rescinded or cancelled prior to such cure.

(g) The Company and the Guarantors agree that, for so long as any Notes remain outstanding, if at any time they are not required to file with the SEC the reports required by Section 4.03(a), the Company and the Guarantors will furnish to the Holders of Notes and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

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

(a) The Issuers and each Guarantor (to the extent that such Guarantor is so required under the TIA) shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of each Issuer and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Issuers have kept, observed, performed and fulfilled their obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Issuers have kept, observed, performed and fulfilled each and every covenant contained in this Indenture and are not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuers are taking or propose to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of, or premium, if any, or interest and Liquidated Damages, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Issuers are taking or propose to take with respect thereto.

(b) So long as any of the Notes are outstanding, the Issuers will deliver to the Trustee, within five Business Days of any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Issuers are taking or propose to take with respect thereto.

The Company will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of Notes.

Each of the Issuers and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and each of the Issuers and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any other payment or distribution on account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company and other than dividends or distributions payable to the Company or a Restricted Subsidiary);

(2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company or any direct or indirect parent of the Company;

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries; provided that the priority that any series of preferred stock of a Restricted Subsidiary has in receiving dividends or liquidating distributions before dividends or liquidating distributions are paid in respect of common stock of such Restricted Subsidiary shall not constitute a restriction on the ability to pay dividends or make distributions on Capital Stock for purposes of this Section 4.08(a);

(2) make loans or advances to the Company or any of its Restricted Subsidiaries (it being understood that the subordination of loans or advances made to the Company or any such Restricted Subsidiary to other Indebtedness incurred by the Company or any such Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances for purposes of this Section 4.08(a)); or

(3) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

(b) However, the restrictions in Section 4.08(a) will not apply to encumbrances or restrictions existing under or by reason of:

(3) applicable law, rule, regulation, order, approval, license, permit or similar restriction;

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired and any amendments, modifications, restatements, renewals, extensions, increases, supplements, refundings, replacements or refinancings thereof; provided that the encumbrances or restrictions contained in any amendments, modifications, restatements, renewals, extensions, increases, supplements, refundings, replacements or refinancings are, in the reasonable good faith judgment

of the Chief Financial Officer of the General Partner, not materially more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided, further, that, in the case of Indebtedness, the incurrence of such Indebtedness was permitted by the terms of this Indenture;

(5) customary non-assignment provisions in contracts or licenses, easements or leases, in each case, entered into in the ordinary course of business;

(10) provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements (including, but not limited to, agreements entered into in connection with a Restricted Investment) entered into in the ordinary course of business or entered into with the approval of the Company’s Board of Directors;

(11) any agreement or instrument relating to any property or assets acquired after the Issue Date, so long as such encumbrance or restriction relates only to the property or assets so acquired and is not and was not created in anticipation of such acquisition;

(12) encumbrances or restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

(13) the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such preferred stock is permitted pursuant to Section 4.09 and the terms of such preferred stock do not expressly restrict the ability of such Restricted Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred stock prior to paying any dividends or making any other distributions on such other Capital Stock);

(14) obligations under Hedging Contracts permitted from time to time under this Indenture;

event of a payment default or a default with respect to a financial covenant in such agreement or instrument or (b) will not materially affect the Company’s ability to make payments with respect to the principal of, or the interest and premium, if any, on, the Notes, as determined in the reasonable good faith judgment of the Chief Executive Officer or the Chief Financial Officer of the General Partner; and

(16) any other agreement governing Indebtedness permitted to be incurred by Section 4.09 and any amendments, modifications, restatements, renewals, extensions, increases, supplements, refundings, replacements or refinancings of those agreements; provided, that the encumbrances or restrictions in such agreements are, in the reasonable good faith judgment of the Chief Financial Officer of the General Partner, not materially more restrictive, taken as a whole, than those contained in this Indenture or the Credit Agreement, in each case, as in effect on the Issue Date.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”; with “incurrence” having a correlative meaning) any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock, and will not permit any of its Restricted Subsidiaries to issue any preferred stock; provided, however, that the Issuers may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and any of the Guarantors may incur Indebtedness (including Acquired Debt) or issue preferred stock, if, for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued, the Fixed Charge Coverage Ratio of the Company would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the preferred stock had been issued, as the case may be, at the beginning of such four-quarter period.

(b) Notwithstanding the foregoing, the provisions of Section 4.09(a) will not prohibit the incurrence of any of the following items of Indebtedness or issuances of Disqualified Stock or preferred stock, as applicable (collectively, “Permitted Debt”):

(1) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness and letters of credit under one or more Credit Facilities, provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) does not exceed the greater of (a) $400.0 million and (b) $250.0 million plus 25% of the Company’s Consolidated Net Tangible Assets;

(2) the incurrence by the Company or its Restricted Subsidiaries of Existing Indebtedness;

(3) the incurrence by the Issuers and the Guarantors of Indebtedness represented by (a) the Notes and the related Note Guarantees to be issued on the Issue Date and (b) the Exchange Notes and the related Note Guarantees to be issued pursuant to any Registration Rights Agreement;

(4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4) at any time; provided that, immediately after giving effect to any such incurrence, the principal amount of all Indebtedness incurred pursuant to this clause (4) and then outstanding does not exceed the greater of (a) $35.0 million and (b) 5% of the Company’s Consolidated Net Tangible Assets;

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease, refund, discharge or otherwise retire for value, any Indebtedness (other than intercompany Indebtedness) or Disqualified Stock of the Company, or Indebtedness (other than intercompany Indebtedness) or preferred stock of any Restricted Subsidiary, in each case, that was permitted by this Indenture to be incurred under Section 4.09(a) or clause (2), (3), (4), (11), (12) or (15) of this Section 4.09(b) or this clause (5);

(6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that:

(A) if the Company or any Guarantor is the obligor on such Indebtedness and neither the Company nor a Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case where the Company is the obligor, or the Note Guarantee, in the case where a Guarantor is the obligor; and

(B)(i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) the incurrence by the Company or any of its Restricted Subsidiaries of obligations under Hedging Contracts in the ordinary course of business and not for speculative purposes;

(8) the Guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or any of its Restricted Subsidiaries that was permitted to be incurred by another provision of this Section 4.09;

(9) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of any preferred stock; provided, however, that:

(A) any subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary; and

(B) any sale or other transfer of any such preferred stock to a Person that is neither the Company nor a Restricted Subsidiary,

will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (9);

(10) the incurrence by the Company or any of its Restricted Subsidiaries of liability in respect of the Indebtedness of any Unrestricted Subsidiary or any Joint Venture but only to the extent that such liability is the result of the Company’s or any such Restricted Subsidiary’s being a general partner or member of, or owner of an Equity Interest in, such Unrestricted Subsidiary or Joint Venture and not as a guarantor of such Indebtedness; provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (10) and then outstanding does not exceed $25.0 million;

(11) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Acquisition Indebtedness;

(12) the incurrence by any Foreign Subsidiary of Indebtedness that, in the aggregate together with all other Indebtedness of all Foreign Subsidiaries (including all Permitted Refinancing Indebtedness incurred to extend, refinance, renew, replace, defease, refund, discharge or otherwise retire for value any Indebtedness incurred pursuant to this clause (12)), does not exceed the greater of (a) $75.0 million and (b) 25% of the Consolidated Net Tangible Assets of all Foreign Subsidiaries, considered as a single enterprise;

(13) the incurrence by the Company or any Restricted Subsidiary of Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of the Company and its Restricted Subsidiaries;

(14) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness constituting reimbursement obligations with respect to letters of credit; provided that, upon the drawing of such letters of credit, such obligations are reimbursed within 30 days following such drawing; and

(15) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness and the issuance by the Company of any Disqualified Stock, provided that, after giving effect to any such incurrence or issuance, the amount of all such Indebtedness and Disqualified Stock incurred or issued pursuant to this clause (15) and then outstanding (including all Permitted Refinancing Indebtedness and Disqualified Stock incurred to extend, refinance, renew, replace, defease, refund, discharge or otherwise retire for value any Indebtedness or Disqualified Stock incurred or issued pursuant to this clause (15)) does not exceed the greater of (a) $35.0 million and (b) 5% of the Company’s Consolidated Net Tangible Assets.

(c) For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness (including Acquired Debt) meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (15) of Section 4.09(b), or is entitled to be incurred pursuant to Section 4.09(a), the Company will be permitted in its sole discretion to divide, redivide, classify or reclassify such item of Indebtedness on the date of its incurrence, and later divide, redivide, classify or reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Any Indebtedness under the Credit Agreement outstanding on the Issue Date shall be deemed to have been incurred on such date pursuant to clause (1) of the definition of Permitted Debt. The accrual of interest or dividends with respect to preferred stock, the accretion

or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this Section 4.09, provided that, in each such case, the amount thereof is included in Fixed Charges of the Company as accrued to the extent required by the definition of such term. Further, the reclassification of any obligation of the Company or any of its Restricted Subsidiaries as Indebtedness due to a change in accounting principles will not be deemed an incurrence of Indebtedness for purposes of this Section 4.09.

(d) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. The principal amount of any Permitted Refinancing Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Company or any of its Restricted Subsidiaries, as the case may be, receives consideration (including by way of relief from, or any Person assuming responsibilities for, any liabilities (other than any contingent liabilities)) at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received by the Company or its Restricted Subsidiaries in the Asset Sale (considered together on a cumulative basis, with all consideration received by the Company or any of its Restricted Subsidiaries in respect of other Asset Sales consummated since the Issue Date) is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:

(A) any liabilities, as shown on the Company’s or any of its Restricted Subsidiaries’ most recent balance sheet, of the Company or such Restricted Subsidiary (other than contingent liabilities and Subordinated Debt) that are assumed by the transferee of any such assets pursuant to a customary novation or indemnity agreement (or other legal documentation with the same effect) that releases the Company or such Restricted Subsidiary from or indemnifies the Company or such Restricted Subsidiary against further liability;

(B) any securities, notes or other obligations received by the Company or any of its Restricted Subsidiaries from such transferee that are, within 90 days after the Asset Sale, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion;

(D) any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in respect of such Asset Sale.

(b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale or, if the Company or any of its Restricted Subsidiaries has entered into a binding commitment or commitments with respect to any of the actions described in clauses (2) or (3) below, within the later of (x) 365 days after the receipt of any Net Proceeds from an Asset Sale and (y) 180 days after the entering into of such commitment or commitments, the Company or any of its Restricted Subsidiaries may apply an amount equal to the amount of such Net Proceeds at its option to any combination of the following:

(1) to repay, redeem or repurchase any Senior Debt, provided that such repayment, redemption or repurchase may close up to 60 days after the end of such 365-day period;

Pending the final application of any Net Proceeds, the Company or any of its Restricted Subsidiaries may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

(c) An amount equal to any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses (1) through (3) of Section 4.10(b) will constitute “Excess Proceeds.” Within ten Business Days after the aggregate amount of Excess Proceeds exceeds $30.0 million, the Company will make an offer (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets, to repurchase the maximum principal amount of Notes and to purchase, prepay or redeem such other pari passu Indebtedness (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest and Liquidated Damages, if any, to the date of repurchase, prepayment or redemption, subject to the rights of Holders on the relevant record date to receive interest and Liquidated Damages, if any, due on an interest payment date that is on or prior to the date of repurchase, prepayment or redemption, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any of its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount

of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis (except that any Notes represented by a Note in global form will be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law), based on the amounts tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000 or an integral multiple of $1,000 in excess of $2,000 will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(d) Notwithstanding the foregoing paragraphs of this Section 4.10, the sale, conveyance or other disposition of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries, taken as a whole, will be governed by the provisions of Section 4.14 and/or Section 5.01 and not by this Section 4.10.

(e) 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 each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.10, or compliance with this Section 4.10 would constitute a violation of any such laws or regulations, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance.

(f) In the event that, pursuant to the preceding provisions of this Section 4.10, the Issuers are required to commence an Asset Sale Offer, the Issuers will follow the procedures specified below.

(1) The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale 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 all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

(2) 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 Liquidated Damages, 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 Sale Offer.

(3) Upon the commencement of an Asset Sale Offer, the Company will send a notice to the Trustee and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(A) that the Asset Sale Offer is being made pursuant to this Section 4.10 and the length of time the Asset Sale Offer will remain open;

(D) that, unless the Issuers default in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date;

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

(F) that Holders electing to have Notes purchased pursuant to any Asset Sale 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;

(G) that Holders 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 letter or electronic transmission setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

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

(I) 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).

(4) On or before the Purchase Date, the Issuers will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes 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 4.10. 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 Issuers will promptly issue a new Note, and the Trustee, upon written request from the Issuers, 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 Sale Offer on the Purchase Date.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”), unless:

(1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Board of Directors of the Company, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view; and

(2) the Company delivers to the Trustee, with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.11 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by either the Conflicts Committee of the Board of Directors of the Company (so long as the members of the Conflicts Committee approving the Affiliate Transaction or series of related Affiliate Transactions are disinterested) or a majority of the disinterested members of the Board of Directors of the Company, if any.

(b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.11(a):

(1) any transaction or series of related transactions involving aggregate consideration of less than $5.0 million;

(2) any employment, consulting or similar agreement or arrangement, employee benefit plan, equity award, equity option, equity appreciation agreement or plan, officer or director indemnification agreement, restricted unit agreement, severance agreement or other compensation plan or arrangement entered into by the General Partner, the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments, awards, grants or issuances of securities made pursuant to the foregoing agreements, arrangements or plans;

(3) transactions between or among the Company and/or its Restricted Subsidiaries;

(4) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Company solely because the Company owns, directly or through a Subsidiary, an Equity Interest in, or controls, such Person;

(5) transactions effected in accordance with the terms of agreements that are identified in the Issuers’ Offering Memorandum dated July 29, 2014 pertaining to the offering of $350,000,000 of the Notes, in each case as such agreements are in effect on the Issue Date, and any amendment

or replacement of any of such agreements so long as such amendment or replacement agreement is no less advantageous to the Company in any material respect than the agreement so amended or replaced;

(6) payment of reasonable fees and reimbursements of expenses (pursuant to indemnity arrangements or otherwise) of, and compensation paid to, and indemnity, insurance or other benefits provided on behalf of, officers, directors, employees or consultants of the General Partner, the Company or any of its Restricted Subsidiaries or Affiliates of the Company, including, but not limited to, reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance;

(7) any issuance of Equity Interests (other than Disqualified Stock) to, or receipt of capital contributions from, Affiliates of the Company;

(8) Restricted Payments that do not violate the provisions of Section 4.07 or any Permitted Investments;

(9) payments to the General Partner with respect to reimbursement for expenses in accordance with the Partnership Agreement as in effect on the Issue Date and as it may be amended, provided that any such amendment is not less favorable to the Company in any material respect than the agreement prior to such amendment;

(10) transactions between the Company or any of its Restricted Subsidiaries and any other Person, a director of which is also on the Board of Directors of the Company or any direct or indirect parent company of the Company, and such common director is the sole cause for such other Person to be deemed an Affiliate of the Company or any of its Restricted Subsidiaries; provided, however, that such director abstains from voting as a member of the Board of Directors of the Company or any direct or indirect parent company of the Company, as the case may be, on any transaction with such other Person; and

(11) (a) guarantees by the Company or any of its Restricted Subsidiaries of performance of obligations of Unrestricted Subsidiaries in the ordinary course of business, except for guarantees of Indebtedness in respect of borrowed money, and (b) pledges by the Company or any of its Restricted Subsidiaries of Equity Interests in Unrestricted Subsidiaries securing Non-Recourse Debt for the benefit of lenders or other creditors of Unrestricted Subsidiaries;

(12) payments to an Affiliate in respect of the Notes or the Note Guarantees or any other Indebtedness of the Company or any Restricted Subsidiary on the same basis as concurrent payments made or offered to be made in respect thereof to non-Affiliates;

(13) payment of loans or advances to employees not to exceed $5.0 million in the aggregate at any one time outstanding;

(14) any Affiliate Transaction with a Person in its capacity as a holder of Indebtedness or Capital Stock of the Company or any Restricted Subsidiary if such Person is treated no more favorably than the other holders of Indebtedness or Capital Stock of the Company or such Restricted Subsidiary;

(15) transactions with Unrestricted Subsidiaries, customers, clients, suppliers or purchasers or sellers of goods or services, or lessors or lessees of property, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which

are, in the aggregate (taking into account all the costs and benefits associated with such transactions), not materially less favorable to the Company and its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated person, in the good faith determination of the Company’s Board of Directors or any officer of the Company involved in or otherwise familiar with such transaction, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

(16) any transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal, advisory or investment banking firm of national standing stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of clause (1) of Section 4.11(a); and

(17) in the case of contracts for gathering, transporting, treating, processing, marketing, distributing, storing or otherwise handling Hydrocarbons, or activities or services reasonably related or ancillary thereto, or other operational contracts, any such contracts that are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by the Company or any of its Restricted Subsidiaries and third parties, or if neither the Company nor any of its Restricted Subsidiaries has entered into a similar contract with a third party, then the terms of which are no less favorable than those available from third parties on an arm’s-length basis.

The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, now owned or hereafter acquired, unless the Notes or any Note Guarantee, as applicable, are secured on an equal and ratable basis with (or on a senior basis to, in the case of Subordinated Debt) the Indebtedness so secured until such time as such Indebtedness is no longer secured by a Lien (other than a Permitted Lien).

Any Lien securing the Notes or Note Guarantees created pursuant to the preceding paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the unconditional release and discharge of the initial Lien whose existence resulted in the creation of such Lien securing the Notes or Note Guarantees.

Finance Corp. will not hold any material assets, become liable for any material obligations, engage in any trade or business, or conduct any business activity, other than the issuance of capital stock to the Company or any of its Restricted Subsidiaries, the incurrence of Indebtedness as a co-issuer, co-obligor or guarantor of Indebtedness incurred by the Company (including without limitation the Notes) that is permitted to be incurred by the Company under Section 4.09, and activities incidental thereto.

(a) If a Change of Control occurs, unless the Issuers have previously or concurrently exercised their right to redeem all of the Notes as set forth in the Notes and in Section 3.07, each Holder of Notes will have the right, except as provided below, to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that Holder’s

Notes pursuant to an offer (a “Change of Control Offer”) on the terms set forth in this Indenture. In the Change of Control Offer, the Company will offer to make a cash payment (a “Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Liquidated Damages, if any, on the Notes repurchased to the date of repurchase (the “Change of Control Settlement Date”), subject to the rights of Holders on the relevant record date to receive interest and Liquidated Damages, if any, due on an interest payment date that is on or prior to the Change of Control Settlement Date. Within 30 days following any Change of Control, unless the Issuers have previously or concurrently exercised their right to redeem all of the Notes as set forth in the Notes and in Section 3.07, the Company will send a notice to each Holder of Notes describing the transaction or transactions that constitute the Change of Control and offering to repurchase properly tendered Notes on the Change of Control Settlement Date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is sent. Furthermore, such notice shall state:

(1) that the Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes tendered will be accepted for payment;

(4) that, unless the Issuers default 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 Settlement 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 Settlement 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 Settlement Date, a letter or electronic transmission 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 as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, or compliance with the provisions of this Section 4.14 would constitute a violation of any such laws or regulations, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.14 by virtue of such compliance.

(b) Promptly following the expiration of the Change of Control Offer, the Company will, to the extent lawful, accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer. Promptly after such acceptance, the Company will, on the Change of Control Settlement Date:

(1) 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

(2) 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.

On the Change of Control Settlement Date, the Paying Agent will send to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment through the facilities of the Depositary), 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, however, that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. Any Note so accepted for payment will cease to accrue interest on and after the Change of Control Settlement Date, unless the Company defaults in making the Change of Control Payment. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Settlement Date.

(c) Notwithstanding any provision to the contrary, the Company will not be required to make a Change of Control Offer upon a Change of Control, if (1) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in Section 4.14(a) applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, (2) notice of redemption of all outstanding Notes has been given pursuant to Section 3.07 unless and until there is a default in payment of the applicable redemption price or (3) in connection with or in contemplation of any Change of Control, the Company has made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Notes properly tendered in accordance with the terms of the Alternate Offer. Notwithstanding anything to the contrary contained herein, a Change of Control Offer or Alternate Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer or Alternate Offer is made.

(d) In the event that Holders of not less than 90% in aggregate principal amount of the outstanding Notes accept a Change of Control Offer or Alternate Offer and the Company (or any third party making such Change of Control Offer in lieu of the Company as set forth in Section 4.14(c)) purchases all of the Notes held by such Holders, the Company will have the right set forth in Section 3.07(c) to redeem all of the Notes that remain outstanding.

If, after the Issue Date, any Domestic Subsidiary of the Company that is not already a Guarantor Guarantees or otherwise becomes obligated with respect to any Indebtedness of the Company or any Guarantor under any Credit Facility, then that Domestic Subsidiary will become a Guarantor by executing a supplemental indenture and delivering it to the Trustee within 20 Business Days of the date on which it Guaranteed such Indebtedness; provided, however, that the preceding shall not apply to Subsidiaries of

the Company that have properly been designated as Unrestricted Subsidiaries in accordance with this Indenture for so long as they continue to constitute Unrestricted Subsidiaries. Notwithstanding the preceding, any Note Guarantee of a Restricted Subsidiary that was incurred pursuant to this paragraph will be released as provided in Section 10.05.

The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.07 or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors of the Company giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by the under Section 4.07. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 the Company will be in default of such covenant.

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09 calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable four-quarter reference period and (2) no Default or Event of Default would be in existence following such designation.

If at any time (a) the Notes have an Investment Grade Rating from at least two Rating Agencies, (b) no Default has occurred and is continuing under this Indenture and (c) the Company has delivered to the Trustee an Officers’ Certificate certifying as to the satisfaction of the conditions set forth in the foregoing clauses (a) and (b) of this sentence, the Company and its Restricted Subsidiaries will no longer be subject to the provisions of Section 4.07, Section 4.08, Section 4.09, Section 4.10, Section 4.11, Section 4.14 and clause (4) of Section 5.01(a).

(a) Neither of the Issuers may (x) consolidate or merge with or into another Person (regardless of whether such Issuer is the surviving entity), or (y) sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person, unless:

(B) the Person formed by or surviving any such consolidation or merger (if other than such Issuer) or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made is a Person organized or existing under the laws of the United States, any state of the United States or the District of Columbia; provided, however, that Finance Corp. may not consolidate or merge with or into any Person other than a corporation satisfying such requirement so long as the Company is not a corporation;

(2) the Person formed by or surviving any such consolidation or merger (if other than such Issuer) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition has been made assumes all the obligations of such Issuer under the Notes and this Indenture (and the Registration Rights Agreement, if any obligations under such agreement remain unsatisfied) pursuant to a supplemental indenture or other agreement reasonably satisfactory to the Trustee;

(4) in the case of a transaction involving the Company and not Finance Corp., after giving effect to such transaction and any related financing transactions on a pro forma basis as if the same had occurred at the beginning of the applicable four-quarter period, either (a) the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made, would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) or (b) the Fixed Charge Coverage Ratio of the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made, is equal to or greater than the Fixed Charge Coverage Ratio of the Company immediately before such transaction; and

(5) such Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or disposition and, if a supplemental indenture is required, such supplemental indenture, comply with this Indenture.

(b) Notwithstanding the foregoing, the restrictions set forth in clause (4) of Section 5.01(a) will not apply to (x) any consolidation or merger of the Company with or into one of its Restricted Subsidiaries for any purpose or (y) any sale, assignment, transfer, conveyance, lease or other disposition of properties or assets of a Restricted Subsidiary (other than Finance Corp.) to the Company or another Restricted Subsidiary that is a Guarantor.

(c) Notwithstanding Section 5.01(a), the Company is permitted to reorganize as any other form of entity, provided that:

(1) the reorganization involves the conversion (by merger, sale, contribution or exchange of assets or otherwise) of the Company into a form of entity other than a limited partnership formed under Delaware law;

(2) the entity so formed by or resulting from such reorganization is an entity organized or existing under the laws of the United States, any state thereof or the District of Columbia;

(3) the entity so formed by or resulting from such reorganization assumes all the obligations of the Company under the Notes and this Indenture (and the Registration Rights Agreement, if any obligations thereunder remain unsatisfied) pursuant to a supplemental indenture or other agreement in a form reasonably satisfactory to the Trustee;

(4) immediately after such reorganization no Default or Event of Default exists; and

(5) such reorganization is not materially adverse to the Holders or Beneficial Owners of the Notes (for purposes of this clause (5), a reorganization will not be considered materially adverse to the Holders or Beneficial Owners of the Notes solely because the successor or survivor of such reorganization (a) is subject to federal or state income taxation as an entity or (b) is considered to be an “includible corporation” of an affiliated group of corporations within the meaning of Section 1504(b) of the Internal Revenue Code or any similar state or local law).

(d) For purposes of this Section 5.01, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries, which properties or assets, if held by the Company instead of such Restricted Subsidiaries, would constitute all or substantially all of the properties or assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties or assets of the Company.

(e) Notwithstanding anything in this Indenture to the contrary, in the event that the Company becomes a corporation or the Company or the Person formed by or surviving any consolidation or merger (permitted in accordance with the terms of this Indenture) is a corporation, Finance Corp. may be merged into the Company or it may be dissolved and cease to be an Issuer.

Upon any consolidation or merger or any sale, assignment, transfer, conveyance, lease or other disposition of all or substantially all of the properties or assets of an Issuer in accordance with Section 5.01 in which such Issuer is not the surviving entity, the surviving Person formed by such consolidation or into or with which such Issuer is merged or to which such sale, assignment, transfer, conveyance, lease or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, such Issuer under this Indenture with the same effect as if such surviving Person had been named as such Issuer in this Indenture, and thereafter (except in the case of a lease of all or substantially all of such Issuer’s properties or assets), such Issuer will be relieved of all obligations and covenants under this Indenture and the Notes.

(1) default for 30 days in the payment when due of interest and Liquidated Damages, if any, on the Notes;

(2) default in the payment when due of the principal of, or premium, if any, on, the Notes;

(3) failure by the Company to comply with its obligations under Section 5.01 or to consummate a purchase of Notes when required pursuant to Section 4.10 or Section 4.14;

(4) failure by the Company or any of its Restricted Subsidiaries for 30 days after written notice from the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes to comply with the provisions of Section 4.07 or Section 4.09 or to comply with the provisions of Section 4.10 or Section 4.14 to the extent not described in clause (3) of this Section 6.01;

(5) (a) except as addressed in subclause (b) of this clause (5), failure by the Company or any of its Restricted Subsidiaries for 60 days after written notice from the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes to comply with any of the other agreements in this Indenture or the Notes or (b) failure by the Company for 180 days after notice from the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes to comply with Section 4.03;

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, if that default:

(A) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or

(B) results in the acceleration of such Indebtedness prior to its Stated Maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $25.0 million or more; provided, however, that if, prior to any acceleration of the Notes, (i) any such Payment Default is cured or waived, (ii) any such acceleration of such Indebtedness is rescinded, or (iii) such Indebtedness is repaid within a period of 10 Business Days from the continuation of such default beyond any applicable grace period for such Payment Default or the occurrence of such acceleration, as the case may be, then any Default or Event of Default (but not any acceleration of the Notes) caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree;

(7) failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company), would constitute a Significant Subsidiary to pay final judgments (entered by a court or courts of competent jurisdiction) aggregating in excess of $25.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed for a period of 60 days;

(8) except as permitted by this Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee, except, in each case, by reason of the release of such Note Guarantee in accordance with this Indenture;

(9) an Issuer or any of the Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law:

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

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

(A) is for relief against any Issuer or any of the Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary in an involuntary case;

(B) appoints a custodian of any Issuer or any of the Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of an Issuer or any of the Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary; or

(C) orders the liquidation of an Issuer or any of the Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary;

In the case of an Event of Default specified in clause (9) or (10) of Section 6.01, with respect to the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, all then outstanding Notes will become due and payable immediately without further action or notice (subject to applicable law). If any other 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 by notice in writing to the Company and, in the case of a notice by such Holders, also to the Trustee specifying the respective Event of Default and that it is a notice of acceleration.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration and its consequences if the rescission would not violate any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium or Liquidated Damages, if any, that has become due solely because of the acceleration) have been cured or waived.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium, if any, on, or interest and Liquidated Damages, if any, on, the Notes or to enforce the performance of any provision of the Notes or this Indenture.

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. A delay or omission by the Trustee or any Holder of a Note 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. All remedies are cumulative to the extent permitted by law.

Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes, waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, on, or interest and Liquidated Damages, if any, on, the Notes; provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability.

Subject to the provisions of Section 7.01, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any Holders unless such Holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest and Liquidated Damages, if any, when due, no Holder may pursue any remedy with respect to this Indenture or the Notes unless:

(1) such Holder has previously given the Trustee written notice that an Event of Default is continuing;

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense;

(4) the Trustee does not comply with such request within 60 days after receipt of the request and the offer of security or indemnity; and

(5) during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request.

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

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, and premium, if any, and interest and Liquidated Damages, if any, on, the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

If an Event of Default specified in clause (1) or (2) of Section 6.01 occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of the principal, premium, if any, or interest and Liquidated Damages, if any, remaining unpaid on the Notes and interest on overdue principal and premium, if any, and to the extent lawful, interest and Liquidated Damages, if any, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

The Trustee is authorized to 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 the Holders of Notes allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the

Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims 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. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. 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 of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.07, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest and Liquidated Damages, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest and Liquidated Damages, if any, respectively; and

Third: to the Issuers or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

(a) If an Event of Default has occurred and is continuing, the Trustee will be required, in the exercise of its power vested in it by this Indenture, to use the degree of care of a prudent man in the conduct of his own affairs.

(1) the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth (or incorporated by reference) in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and opinions to determine whether they conform to the requirements of this Indenture.

(c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(1) this paragraph does not limit the effect of paragraph (b) of this Section 7.01;

(2) the Trustee will not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

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

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

(e) The Trustee will not be liable for interest 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 law.

(a) The Trustee may conclusively rely upon any document reasonably believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(c) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed with due care.

(d) The Trustee will not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture.

(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuers will be sufficient if signed by an Officer of each of the Company and Finance Corp.

(f) No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights or powers under this Indenture at the request of any Holders, unless such Holder has offered to the Trustee reasonable indemnity or security satisfactory to it against any loss, liability or expense that might be incurred by it in connection with its compliance with such request.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers or any Affiliate of the Issuers with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest, it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.10 and Section 7.11.

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuers’ use of the proceeds from the Notes or any money paid to the Issuers or upon the Issuers’ direction under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will send to the Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest and Liquidated Damages, if any, on, any Note, 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 the Holders of Notes.

The Trustee will not be deemed to have notice of any Default or Event of Default, except Events of Default under clause (1) or (2) of Section 6.01, unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event that is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

(a) Within 60 days after each May 15 beginning with the May 15 following the Issue Date, and for so long as Notes remain outstanding, the Trustee will send to the Holders of Notes a brief report dated as of such reporting 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 will comply with TIA § 313(b)(2). The Trustee will also send all reports as required by TIA § 313(c).

(b) A copy of each report at the time it is sent to the Holders of Notes will be mailed by the Trustee to the Issuers and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Issuers will promptly notify the Trustee in writing when the Notes are listed on any stock exchange.

(a) The Issuers will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services provided hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Issuers will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b) The Issuers and the Guarantors, jointly and severally, will indemnify the Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuers and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuers, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence, bad faith or willful misconduct. The Trustee will notify the Issuers and the Guarantors promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers and the Guarantors will not relieve the Issuers or any of the Guarantors of their obligations hereunder unless the failure to notify the Issuers or the Guarantors impairs any Issuer’s or Guarantor’s respective ability to defend such claim. Such Issuer or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Issuers will pay the reasonable fees and expenses of such counsel. Neither Issuer nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

(c) The obligations of the Issuers and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture.

(d) To secure the Issuers’ and the Guarantors’ payment obligations in this Section 7.07, the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of and interest and Liquidated Damages, if any, on, particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in clause (9) or (10) of Section 6.01 occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

(f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable.

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

(b) The Trustee may resign in writing at any time and be discharged from the trust hereby created only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may remove the Trustee if:

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

(3) a custodian or public officer takes charge of the Trustee or its property; or

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuers will promptly appoint a successor Trustee. Within one year after such successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuers.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuers, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

(e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will send a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuers’ obligations under Section 7.07 will continue for the benefit of the retiring Trustee.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another Person, the successor Person without any further act will be the successor Trustee.

There will at all times be a Trustee hereunder that is a corporation or banking association organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of condition.

This Indenture will always have a Trustee who satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b).

The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. The Trustee hereby waives any right to set off any claim that it may have against the Issuers in any capacity (other than as Trustee and Paying Agent) against any of the assets of the Issuers held by the Trustee; provided, however, that if the Trustee is or becomes a lender of any other Indebtedness permitted hereunder to be pari passu with the Notes, then such waiver shall not apply to the extent of such Indebtedness.

The Issuers may at any time, at the option of their respective Boards of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02 or Section 8.03 be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Upon the Issuers’ exercise under Section 8.01 of the option applicable to this Section 8.02, each Issuer and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or premium, if any, or interest and Liquidated Damages, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04;

(2) the Issuers’ obligations with respect to the Notes under Section 2.04, Section 2.06, Section 2.07, Section 2.10 and Section 4.02;

(3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuers’ and the Guarantors’ obligations in connection therewith; and

Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03.

Upon the Issuers’ exercise under Section 8.01 of the option applicable to this Section 8.03, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04, be released from each of their obligations under Section 4.03, Section 4.07, Section 4.08, Section 4.09, Section 4.10, Section 4.11, Section 4.12, Section 4.13, Section 4.14, Section 4.15, Section 4.16, Section 4.17 and Section 5.01(a)(4) with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (such release and termination hereinafter referred to as “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuers and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.01 of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04, clauses (3) through (7) of Section 6.01 and, only with respect to Subsidiaries of the Company, clauses (9) and (10) of Section 6.01 will not constitute Events of Default.

In order to exercise either Legal Defeasance under Section 8.02 or Covenant Defeasance under Section 8.03:

(1) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm, or firm of independent public accountants, to pay the principal of, or premium, if any, or interest and Liquidated Damages, if any, on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Issuers must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date;

(2) in the case of an election under Section 8.02, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

(A) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling; or

(B) since the Issue Date, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to 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;

(3) in the case of an election under Section 8.03, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Issuers or any of the Guarantors is a party or by which the Issuers or any of the Guarantors is bound;

(6) the Issuers must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuers with the intent of preferring the Holders of Notes over the other creditors of the Issuers with the intent of defeating, hindering, delaying or defrauding any other creditors of the Issuers or others;

(7) the Company must deliver to the Trustee an Officers’ Certificate, stating that all conditions precedent set forth in clauses (1) through (6) of this Section 8.04 have been complied with; and

(8) the Company must deliver to the Trustee an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions, qualifications and exclusions), stating that all conditions precedent set forth in clauses (2), (3) and (5) of this Section 8.04 have been complied with; provided that the Opinion of Counsel with respect to clause (5) of this Section 8.04 may be to the knowledge of such counsel.

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee pursuant to Section 8.04 in respect of the outstanding Notes will 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 (including an Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest and Liquidated Damages, if any, but such money need not be segregated from other funds except to the extent required by law.

The Issuers will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Issuers from time to time, upon the request of the Issuers any money or non-callable Government Securities held by it as provided in Section 8.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under clause (1) of Section 8.04), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, premium, if any, or interest and Liquidated Damages, if any, on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest and Liquidated Damages, if any, has become due and payable shall be paid to the Company on its request or (if then held by the Issuers) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of each such Issuer as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuers cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or Section 8.03, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or Section 8.03 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or Section 8.03, as the case may be; provided, however, that, if the Issuers make any payment of principal of, premium, if any, or interest and Liquidated Damages, if any, on, any Note following the reinstatement of its obligations, the Issuers will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

Notwithstanding Section 9.02, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or the Note Guarantees without the consent of any Holder of Notes:

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(3) to provide for the assumption of an Issuer’s or a Guarantor’s obligations to Holders of Notes and Note Guarantees in the case of a merger or consolidation or sale of all or substantially all of such Issuer’s or Guarantor’s properties or assets, as applicable;

(4) to make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the legal rights under this Indenture of any such Holder;

(5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA;

(6) to conform the text of this Indenture or the Notes to any provision of the “Description of Notes” section of the Issuers’ Offering Memorandum dated July 29, 2014, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Notes or the Note Guarantees;

(7) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the Issue Date;

(9) to add any Note Guarantees or to evidence the release of any Guarantor from its Note Guarantee, in each case as provided in this Indenture; or

(10) to evidence or provide for the acceptance of appointment under this Indenture of a successor Trustee.

Upon the request of the Issuers accompanied by resolutions of their respective Boards of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02, the Trustee will join with the Issuers and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Except as provided below in this Section 9.02, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture (including, without limitation, Section 4.10 and Section 4.14), the

Notes and the Note Guarantees with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or Exchange Offer for, Notes), and, subject to Section 6.04 and Section 6.07, any existing Default or Event of Default or compliance with any provision of this Indenture, 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 voting as a single class (including consents obtained in connection with a purchase of, or tender offer or Exchange Offer for, Notes).

Upon the request of the Issuers accompanied by resolutions of their respective Boards of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02, the Trustee will join with the Issuers and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture.

It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. Subject to Section 6.04 and Section 6.07, the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture, the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes; provided, however, that any purchase or repurchase of Notes, including pursuant to Section 4.10 and Section 4.14, shall not be deemed a redemption of the Notes;

(3) reduce the rate of or change the time for payment of interest, including default interest, on any Note;

(4) waive a Default or Event of Default in the payment of principal of, premium, if any, or interest and Liquidated Damages, if any, on, the Notes (except a rescission of acceleration of the Notes by the Holders of a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, premium, if any, or interest and Liquidated Damages, if any, on, the Notes;

(7) waive a redemption payment with respect to any Note; provided, however, that any purchase or repurchase of Notes, including pursuant to Section 4.10 and Section 4.14, shall not be deemed a redemption of the Notes;

(8) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or

(9) make any change in the preceding amendment, supplement and waiver provisions.

Every amendment or supplement to this Indenture or the Notes will be set forth in an amended or supplemental indenture that complies with the TIA as then in effect.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any 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.

The Issuers may fix a record date for determining which Holders must consent to such amendment, supplement or waiver. If the Issuers fix a record date, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation pursuant to Section 2.05, or (ii) such other date as the Issuers shall designate.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuers in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

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

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. No Issuer may sign an amended or supplemental indenture until its Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01) will be fully protected in relying upon, in addition to the documents required by Section 12.04, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

(a) Subject to this Article 10, 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 this Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that:

(1) the principal of, premium, 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, premium, if any, and interest on, the Notes, if lawful (subject in all cases to any applicable grace period provided herein), and all other obligations of the Issuers 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, to the maximum extent permitted under applicable law, their obligations hereunder are 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 the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against any Issuer, any action to enforce the same or any other circumstance that might otherwise constitute a legal or equitable discharge or defense of a Guarantor. To the extent permitted by applicable law, each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against an Issuer, protest, notice and all demands whatsoever and covenant that the Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid by either to the Trustee or such Holder, the Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(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, to the extent permitted by applicable law, 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 6 for the purposes of the 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 6, such obligations (regardless of whether due and payable) will forthwith become due and payable by the Guarantors for the purpose of the Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

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 such 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 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

To evidence its Note Guarantee set forth in Section 10.01, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 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 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 Indenture on behalf of the Guarantors.

In the event that either Issuer or any of its Restricted Subsidiaries creates or acquires any Domestic Restricted Subsidiary after the Issue Date, if required by Section 4.15, the Company will cause such Domestic Restricted Subsidiary to comply with the provisions of Section 4.15 and this Article 10, to the extent applicable.

Except as otherwise provided in Section 10.05, no Guarantor may sell or otherwise dispose of, in one or more related transactions, all or substantially all of its properties or assets to, or consolidate with or merge with or into (regardless of whether such Guarantor is the surviving Person), another Person, other than the Company or another Guarantor, unless:

(1) immediately after giving effect to such transaction or series of related transactions, no Default or Event of Default exists; and

(A)(i) such Guarantor is the surviving Person of such consolidation or merger or (ii) the Person acquiring the properties or assets in any such sale or other disposition or the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) unconditionally assumes all the obligations of such Guarantor under the Notes and this Indenture (including its Note Guarantee) pursuant to a supplemental indenture satisfactory to the Trustee; or

(B) such transaction or series of transactions does not violate the provisions of Section 4.10.

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor.

Except as set forth in Article 4 and Article 5, and notwithstanding clauses (A) and (B) immediately above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

(1) in connection with any sale or other disposition of all or substantially all of the properties or assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition does not violate the provisions of Section 4.10;

(2) in connection with any sale or other disposition of the Capital Stock of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition does not violate the provisions Section 4.10 and the Guarantor ceases to be a Restricted Subsidiary as a result of such sale or other disposition;

(3) if the Company designates such Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture;

(4) upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 or satisfaction and discharge of this Indenture in accordance with Article 11;

(5) upon the liquidation or dissolution of such Guarantor, provided that no Default or Event of Default occurs as a result thereof or has occurred or is continuing;

(6) upon such Guarantor consolidating with, merging into or transferring all of its properties or assets to the Company or another Guarantor and, as a result of or in connection with such transaction, such Guarantor dissolves or otherwise ceases to exist; or

(7) at such time as such Guarantor is no longer required to Guarantee any Indebtedness of the Company, Finance Corp. or any other Guarantor under any Credit Facility.

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of, premium, if any, and interest on, the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

This Indenture will be satisfied and discharged and will cease to be of further effect as to all Notes issued hereunder (except as to surviving rights of registration of transfer or exchange of the Notes and as otherwise specified in this Indenture), when:

(A) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Issuers, have been delivered to the Trustee for cancellation; or

(B) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the sending of a notice of redemption or otherwise or will become due and payable within one year and either an Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal of, premium, if any, and interest and Liquidated Damages, if any, on, the Notes to the date of maturity or redemption;

(2) in respect of clause (B) of Section 11.01(1), no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other material instrument to which either Issuer or any Guarantor is a party or by which either Issuer or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and, in each case, the granting of Liens to secure such borrowings);

(3) the Issuers have, or any Guarantor has, paid or caused to be paid all sums payable by them under this Indenture; and

(4) the Issuers have delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be.

In addition, the Issuers must deliver to the Trustee (a) an Officers’ Certificate, stating that all conditions precedent set forth in clauses (1) through (4) of this Section 11.01 have been satisfied and (b) an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and qualifications), stating that the condition precedent set forth in clause (4) of this Section 11.01 has been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to clause (B) of Section 11.01(1), the provisions of Section 11.02 and Section 8.06 will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 that, by their terms, survive the satisfaction and discharge of this Indenture.

Subject to the provisions of Section 8.06, all money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by the Trustee, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including an Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest and Liquidated Damages, if any, for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 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 Issuers’ and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01; provided that if the Issuers have made any payment of principal of, premium, if any, or interest and Liquidated Damages, if any, on, any Notes because of the reinstatement of its obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

This Indenture is subject to the provisions of the TIA that are required to be a part of this Indenture, and will, to the extent applicable, be governed by such provisions. If any provision of this Indenture modifies any TIA provision that may be so modified, such TIA provision will be deemed to apply to this Indenture as so modified. If any provision of this Indenture excludes any TIA provision that may be so excluded, such TIA provision will be excluded from this Indenture.

If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by TIA § 318(c), the imposed duties will control.

Any notice or communication by the Issuers, any Guarantor or the Trustee to the others is duly given if in writing and delivered in Person or mailed by first class mail (registered or certified, return receipt requested), facsimile or electronic transmission or overnight air courier guaranteeing next day delivery, to the others’ address:

The Issuers, any Guarantor or the Trustee, by notice to the others, may designate additional or different addresses for subsequent notices or communications.

All notices and communications (other than those sent to Holders) will be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if electronically transmitted; when receipt acknowledged, if transmitted by facsimile; or the next Business Day after timely delivery to a courier, if sent by overnight air courier guaranteeing next day delivery.

Any notice or communication to a Holder, when the Notes are in the form of Definitive Notes, will be mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier guaranteeing next day delivery to its address shown on the register kept by the Registrar. Any notice or communication to a Holder, when the Notes are in the form of Global Notes, will be sent pursuant to Applicable Procedures. Any notice or communication will also be so sent to any Person described in TIA § 313(c), to the extent required by the TIA. Failure to send a notice or communication to a Holder or any defect in it will not affect its sufficiency with respect to other Holders.

If a notice or communication is mailed or otherwise sent in the manner provided above within the time prescribed, it is duly given, regardless of whether the addressee receives it (other than with respect to notices or communications by facsimile or electronic transmission, which will be deemed to be duly given when receipt is acknowledged or when answered back, respectively).

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver will be the equivalent of such notice. Waivers of notice by Holders will be filed with the Trustee, but such filing will not be a condition precedent to the validity of any action taken in reliance on such waiver.

If the Issuers send a notice or communication to Holders, they will send a copy to the Trustee and each Agent at the same time.

Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their rights under this Indenture or the Notes. The Issuers, the Trustee, the Registrar and anyone else shall have the protection of TIA § 312(c).

Upon any request or application by the Issuers to the Trustee to take any action under this Indenture, the Issuers shall furnish to the Trustee:

(1) an Officers’ Certificate in form and substance reasonably satisfactory to the Trustee (which must include the statements set forth in Section 12.05) stating that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been satisfied; provided that no such Officers’ Certificate shall be delivered on the Issue Date in connection with the original issuance of the initial Global Notes; and

(2) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee (which must include the statements set forth in Section 12.05) stating that, in the opinion of such counsel (who may rely upon an Officers’ Certificate as to matters of fact), all such conditions precedent and covenants have been satisfied; provided that no such Opinion of Counsel shall be delivered on the Issue Date in connection with the original issuance of the initial Global Notes.

Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to TIA § 314(a)(4)) must comply with the provisions of TIA § 314(e) and must include:

(1) a statement that the Person making such certificate or opinion has read such covenant or condition;

(2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(3) a statement that, in the opinion of such Person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether such covenant or condition has been satisfied; and

(4) a statement as to whether, in the opinion of such Person, such condition or covenant has been satisfied.

The Trustee may make reasonable rules for action taken by, or meetings or consent of, Holders. The Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions.

Section 12.07 No Personal Liability of Directors, Officers, Employees and Unitholders.

None of the General Partner or any director, officer, partner, employee, incorporator, manager, unitholder or other owner of Capital Stock of the General Partner, the Issuers or any Guarantor, as such, will have any liability for any obligations of the Issuers or the Guarantors under the Notes, this Indenture, the Note Guarantees, 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 and the Note Guarantees.

THE LAWS OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE NOTE GUARANTEES.

This Indenture may not be used to interpret any other indenture, loan or debt agreement of either Issuer or its Subsidiaries or of any other Person. Any such indenture, loan or debt agreement may not be used to interpret this Indenture.

All agreements of each Issuer in this Indenture and the Notes will bind its successors. All agreements of the Trustee in this Indenture will bind its successors. All agreements of each Guarantor in this Indenture will bind its successors, except as otherwise provided in Section 10.05.

In case any provision in this Indenture or in the Notes is invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions will not in any way be affected or impaired thereby.

The parties may sign any number of copies of this Indenture. Each signed copy will be an original, but all of them together represent the same agreement.

The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and will in no way modify or restrict any of the terms or provisions hereof.

Capitalized terms used but not defined herein have the meanings given to them in the Indenture.

SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of , 20 , among (the “Guaranteeing Subsidiary”), a subsidiary (or a permitted successor thereof) of Compressco Partners, L.P. (“Compressco Partners”), a Delaware limited partnership, or Compressco Finance Inc. (“Finance Corp.,” and, together with Compressco Partners, the “Issuers”), a Delaware corporation, the Issuers, the other Guarantors (as defined in the Indenture referred to herein) and U.S. Bank National Association, as trustee under the Indenture referred to below (the “Trustee”).

WHEREAS, the Issuers have heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of August 4, 2014 providing for the issuance of 7.25% Senior Notes due 2022 (the “Notes”);

WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuers’ Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of Notes as follows:

1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article 10 thereof.

3. EXECUTION AND DELIVERY. Each Guaranteeing Subsidiary agrees that the Note Guarantees shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

4. NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, partner, employee, incorporator, organizer, manager, unitholder or other owner of Capital Stock (as defined in the Indenture) of the Guaranteeing Subsidiary or agent thereof, as such, shall have any liability for any obligations of the Issuers, the Guarantors, the Guaranteeing Subsidiary or any other Subsidiary of an Issuer providing a Note Guarantee under the Notes, any Note Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the 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. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

5. NEW YORK LAW TO GOVERN. THE LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE.

6. COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.
