The terms “Beneficially Owns” and “Beneficially Owned” have a corresponding meaning.

THE NOTES AND UNITS

Section 2.01 Form and Dating.

(a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A-1 hereto; provided, that the form of the Exchange Notes shall include such variations as are permitted or required by the Registration Rights Agreement (as evidenced by PES’s execution of such Exchange Notes). The Notes may be issued in definitive or global forms hereunder. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in denominations of $2,000 and integral multiples of $1,000 in excess thereof. Notwithstanding any provision of this Indenture or the Notes any pro rata redemptions or repurchases of the Notes by PES pursuant to this Indenture shall be made in a manner that preserves the authorized denominations of the Notes.

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and PES, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

The form of Unit is attached as Exhibit A-2, and the terms and provisions of such are made a part hereof.

(b) Global and Definitive Notes. Notes issued in global form will be substantially in the form of Exhibit A-1 hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A-1 hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

(c) Temporary Global Notes. Notes offered and sold in reliance on Regulation S will be issued initially in the form of the Regulation S Temporary Global Note, which will be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, at its New York office, as custodian for the Depositary, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by PES and authenticated by the Trustee as hereinafter provided. The Restricted Period will be terminated upon the receipt by the Trustee of an Officers’ Certificate from PES.

Following the termination of the Restricted Period, beneficial interests in the Regulation S Temporary Global Note will be exchanged for beneficial interests in the Regulation S Permanent Global Note pursuant to the Applicable Procedures. Simultaneously with the authentication of the Regulation S Permanent Global Note, the Trustee will cancel the Regulation S Temporary Global Note. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided.

Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream will be applicable to transfers of beneficial interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Note that are held by Participants through Euroclear or Clearstream.

Section 2.02 Execution and Authentication.

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

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

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

The Trustee shall authenticate and deliver: (i) on the date of this Indenture, an aggregate principal amount of $115 million of Notes, (ii) any Additional Notes in accordance with Section 4.09 hereof, which shall constitute a distinct issuance of Notes but be considered the same class and shall be in the same form as the Initial Notes and which are not limited in principal amount except as otherwise provided in Section 4.09, and (iii) Exchange Notes for issue only in an Exchange Offer pursuant to the Registration Rights Agreement, for a like principal amount of Notes, in each case upon receipt of a written order of PES signed by two Officers (an “Authentication Order”). Such Authentication Order shall specify the amount of the Notes to be authenticated and the date on which the original issue of the Notes is to be authenticated. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by PES pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

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

Section 2.03 Registrar and Paying Agent.

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

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

PES initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

PES will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the

Paying Agent for the payment of principal, premium or Additional Interest, if any, or interest on the Notes, and will notify the Trustee of any default by PES in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. PES 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 PES or a Subsidiary) will have no further liability for the money. If PES 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 PES, the Trustee will serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

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, PES will furnish to the Trustee at least seven Business Days before each regular record 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 PES shall otherwise comply with TIA § 312(a).

Section 2.06 Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by PES for Definitive Notes if:

(2) PES in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; provided that in no event shall the Regulation S Temporary Global Note be exchanged by PES for Definitive Notes prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or

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.

(i) General Provisions Relating to Transfers and Exchanges.

(1) To permit registrations of transfers and exchanges, PES will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof 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 PES may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith.

(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 PES, 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.

(5) Neither the Registrar nor PES will be required:

(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 pursuant to Section 3.02 hereof 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 PES 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 PES 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 hereof.

and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(k) Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depository.

Section 2.07 Replacement Notes.

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

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

Section 2.08 Outstanding Notes.

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 hereof, a Note does not cease to be outstanding because PES or an Affiliate of PES holds the Note.

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

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

If the Paying Agent (other than PES, 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.

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by PES or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with PES or any 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 a Responsible Officer of the Trustee knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, PES may prepare and execute 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 PES considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, PES will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

PES shall cause definitive Notes to be prepared and authenticated without unreasonable delay. After the preparation of the definitive Notes, the temporary Notes shall be exchanged for definitive Notes upon surrender of the temporary Notes at the office or agency of PES, without charge to the Holder. Upon surrender for cancellation of one or more temporary Notes, PES shall execute and the Trustee shall authenticate and deliver in exchange therefore a like principal amount of definitive Notes of authorized denominations. Until so exchanged, Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

Section 2.11 Cancellation.

PES 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 dispose of canceled Notes (subject to the record retention requirements of the Exchange Act and the Trustee). Certification of the cancellation of all canceled Notes will be delivered to PES upon written request. PES may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. To the extent that any Notes are held in the form of Global Notes and less than all of such Global Notes are to be cancelled, the reduction of the principal amount of any such Global Note and the Registrar’s notation of such cancellation on its books and records shall be deemed to satisfy any cancellation requirement, provided that certification of such cancellation shall be delivered to PES upon written request.

Section 2.12 Defaulted Interest.

If PES defaults in a payment of interest on the Notes, it 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 hereof. PES 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. PES 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, PES (or, upon the written request of PES, the Trustee in the name and at the expense of PES) will mail or cause to be

mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

Section 2.13 CUSIP Numbers.

PES in issuing the Notes may use CUSIP, ISIN or other such numbers (if then generally in use), and, if so, the Trustee shall use CUSIP, ISIN or other such numbers in notices of redemption as a convenience to Holders; provided, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. PES shall promptly notify the Trustee in writing of any change in the CUSIP, ISIN or other numbers.

Section 2.14 Restricted Units.

(a) The Notes and the Warrants shall initially be issued as Units, each Unit being in global form substantially in the form of Exhibit A-2 and bearing the Restricted Units Legend set forth below (“Restricted Units Legend”), and shall not be separately transferable until the Separation Date. Until the Separation Date, the certificates representing the Units shall bear the following legend:

The securities represented by this certificate constitute a portion of one or more Units, each Unit consisting of $1,000 of principal amount of 14.250% Senior Secured Notes due 2015 of the Company and one Warrant to purchase common stock of the Company, par value $0.001 per share, subject to adjustment. The aggregate number of shares of common stock of the Company issuable upon exercise of the warrants shall represent 15% of the outstanding shares of common stock of the Company on a fully-diluted basis as of the consummation of the sale of the units and the Concurrent Equity Offering. Until the Separation Date, the securities represented by this certificate may be transferred only together as a Unit. Following the Separation Date, the securities represented by this certificate may be transferred without reference to the foregoing restriction.

(b) Until the Separation Date, the Registrar shall not register any transfer of a Note that constitutes part of a Unit unless the Registrar receives satisfactory evidence that the Warrant comprising the corresponding part of such Unit is being simultaneously transferred to the same transferee. On the Separation Date, separation of the Units is mandatory and the Units will cease to be eligible for transfer or exchange. Following the Separation Date, any Note that constitutes part of a Unit may be transferred separately from the Warrant comprising the corresponding part of such Unit, and the Registrar shall be authorized to register such transfer without regard to the foregoing restriction.

REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

If PES elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, 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:

(1) the CUSIP number;

(2) the clause of this Indenture pursuant to which the redemption shall occur;

(3) the redemption date;

(4) the principal amount of Notes to be redeemed;

(5) the redemption price; and

(6) the Notes to be redeemed, if a partial redemption.

Section 3.02 Selection and Notice.

If less than all of the Notes or Other Pari Passu Obligations are to be redeemed at any time, the Trustee will select Notes for redemption on a pro rata basis or by lot or similar method (and in the case of Global Notes, in accordance with the procedures of DTC), unless otherwise required by law or applicable stock exchange requirements; provided, that no Notes of $2,000 or less shall be purchased or redeemed in part.

A new Note in principal amount equal to the unpurchased or unredeemed portion of the original Note purchased or redeemed in part will be issued in the name of the Holder of Notes upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of Notes called for redemption.

Section 3.03 Notice of Redemption.

Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a redemption date, PES will mail or cause to be mailed by first class mail (or transmitted otherwise in accordance with the procedures of DTC), a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 12 hereof.

The notice will identify the Notes to be redeemed and will state:

(1) the CUSIP number;

(2) the redemption date;

(3) the redemption price;

(4) 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) the name and address of the Paying Agent;

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

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

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

(9) 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.

At PES’s request, the Trustee will give the notice of redemption in PES’s name and at its expense; provided, however, that PES has delivered to the Trustee, at least 45 days (or such shorter periods as the Trustee shall agree) prior to the redemption date, 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 and stating that all conditions precedent to the giving of such notice have been complied with.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional; provided, however, that a notice of redemption upon any Equity Offering or in connection with a transaction (or series of transactions) that constitute a Change of Control may, at PES’s option and discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the Equity Offering or Change of Control as the case may be.

Section 3.05 Deposit of Redemption or Purchase Price.

One Business Day prior to the redemption or purchase date, PES will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest and Additional Interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to PES any money deposited

with the Trustee or the Paying Agent by PES in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest and Additional Interest, if any, on, all Notes to be redeemed or purchased.

If PES complies 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 PES 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 hereof.

Section 3.06 Notes Redeemed or Purchased in Part.

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

Section 3.07 Optional Redemption.

Additional Interest, if any, thereon, to but not including the redemption date (subject to the rights of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that occurs on or prior to the redemption date), with the net cash proceeds of one or more Equity Offerings of PES, provided that:

(1) at least 65% of the sum of the aggregate principal amount of Notes originally issued under this Indenture (excluding Notes held by PES and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

(2) the redemption occurs within 90 days of the date of the closing of such Equity Offering.

(c) In addition, at any time prior to March 1, 2013, PES may also redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ prior notice mailed by first-class mail to each Holder’s registered address (or transmitted otherwise in accordance with applicable procedures of DTC), with a copy to the Trustee, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium, and accrued and unpaid interest and Additional Interest, if any, to, but not including, the redemption date, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date.

(d) The Trustee shall select the Notes to be purchased in the manner described under Section 3.02.

(e) Notice of redemption upon any Equity Offering or in connection with a transaction (or series of related transactions) that constitute a Change of Control may, at PES’s option and discretion, be subject to one or more conditions precedent, including, but not limited to, completion of an Equity Offering or Change of Control, as the case may be.

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

(g) Except pursuant to the preceding Section 3.07(a), (b) and (c), the Notes will not be redeemable at PES’s option prior to their final maturity.

Section 3.08 Mandatory Redemption; Open Market Purchases.

Except to the extent required pursuant to Sections 4.10 and 4.15, PES is not required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders. PES may at any time and from time to time purchase the Notes in the open market or otherwise if such purchase complies with the then applicable agreements of PES, including this Indenture.

Section 3.09 Offer to Purchase by Application of Excess Proceeds.

(a) In the event that, pursuant to Section 4.10 hereof, PES is required to commence an Asset Sale Offer, it will follow the procedures specified below.

(b) The Asset Sale Offer shall be made to all Holders and, at the option of PES, all holders of Other Pari Passu Obligations. 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 “Asset Sale Offer Period”). No later than three Business Days after the termination of the Asset Sale Offer Period (the “Asset Sale Purchase Date”), PES will apply all Excess Proceeds (the “Asset Sale Offer Amount”) to the purchase of Notes and, if applicable, such Other Pari Passu Obligations (on a pro rata basis, if applicable) or, if less than the Asset Sale Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer.

(c) If the Asset Sale 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 Additional Interest, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no further interest will be payable on such Interest Payment Date to Holders who tender Notes pursuant to the Asset Sale.

(d) Upon the commencement of an Asset Sale Offer, PES will send, by first class mail (or transmit otherwise in accordance with the procedures of DTC), 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:

(1) the CUSIP number;

(2) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof, and the length of time the Asset Sale Offer will remain open;

(3) the Asset Sale Offer Amount, the purchase price and the Asset Sale Purchase Date;

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

(5) that, unless PES defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrete or accrue interest on and after the Asset Sale Purchase Date;

(9) that, if the aggregate principal amount of Notes and Other Pari Passu Obligations surrendered by holders thereof exceeds the Asset Sale Offer Amount, PES will select the Notes and Other Pari Passu Obligations to be purchased on a pro rata basis based on the principal amount of Notes and such Other Pari Passu Obligations surrendered (with such adjustments as may be deemed appropriate by PES so that only Notes in denominations of $2,000 and integral multiples of $1,000 in excess thereof, will be purchased); and

(10) 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), which unpurchased portion must be equal to $2,000 in principal amount or integral multiples of $1,000 in excess thereof.

(e) On or before the Asset Sale Purchase Date, PES will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Asset Sale Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Asset Sale 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 PES in accordance with the terms of this Section 3.09. PES, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Asset Sale 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 PES for purchase, and PES will promptly issue a new Note, and the Trustee, upon written request from PES, 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.

COVENANTS

Section 4.01 Payment of Notes.

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

PES will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest (without regard to any applicable grace period) at the same rate to the extent lawful.

Section 4.02 Maintenance of Office or Agency.

PES 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 PES in respect of the Notes and this Indenture may be served. PES will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time PES fails 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.

PES 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 PES of its obligation to maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. PES 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.

All notices to the Trustee or the Collateral Agent hereunder shall be sent to the Corporate Trust Office at the address set forth in Section 13.02 hereof, however, in addition, PES hereby designates a corporate trust office of the Trustee located at 101 Barclay Street, New York, NY 10286, Attn: Corporate Trust Administration as one such office or agency in the Borough of Manhattan of PES in accordance with Section 2.03 hereof.

Section 4.03 Reports.

Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, PES will furnish to the Holders of Notes and the Trustee, and make available on a publicly available website, within the time periods specified in the SEC’s rules and regulations:

(1) all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if PES were required to file such reports; and

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

Upon request by PES, the Trustee shall transmit such reports to the Holders (or DTC, as long as the Notes are held in global form).

Notwithstanding the foregoing, no such reports shall be required to comply with sections 302, 906, and 404 of the Sarbanes-Oxley Act of 2002 and Items 307 and 308 of Regulation S-K under the Securities Act, in each case, until such time as PES shall have consummated an Exchange Offer or filed a Shelf Registration Statement in respect of the Notes.

All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each annual report on Form 10-K will include a report on PES’s consolidated financial statements by PES’s independent registered public accounting firm. In addition, following the consummation of the Exchange Offer contemplated by the Registration Rights Agreement, PES will file a copy of each of the reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the rules and regulations applicable to such reports (unless the SEC will not accept such a filing) and will post the reports on its website within those time periods.

If, at any time following the consummation of the Exchange Offer contemplated by the Registration Rights Agreement, PES is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, PES will nevertheless continue filing the reports specified in the preceding paragraphs of this Section 4.03 with the SEC within the time periods specified above unless the SEC will not accept such a filing. PES will not take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept PES’s filings for any reason, PES will post the reports referred to in the preceding paragraphs on its website within the time periods that would apply if PES were required to file those reports with the SEC.

PES will hold a quarterly conference call for the Holders of the Notes, prospective purchasers and securities analysts to discuss such financial information no later than ten Business Days after distribution of such financial information.

If PES has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraphs 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 PES and its Restricted

Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of PES.

In addition, PES agrees that, for so long as any of the Notes remain outstanding, if at any time it is not required to file with the SEC the reports required by the preceding paragraphs, it 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.

Section 4.04 Compliance Certificate.

(a) PES 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 PES and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether PES has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge PES has kept, observed, performed and fulfilled each and every covenant contained herein; and is 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 PES is taking or proposes 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 interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action PES is taking or proposes to take with respect thereto.

(b) So long as any of the Notes are outstanding, PES will deliver to the Trustee, forthwith upon any Officer of PES becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action PES is taking or proposes to take with respect thereto.

Section 4.05 Taxes; Stay, Extension and Usury Laws.

(a) PES 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 the Notes.

(b) PES 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 PES 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.

Section 4.06 Excess Cash Flow Offer.

(a) Within 100 days after each Determination Date for which the Excess Cash Flow of PES and its Restricted Subsidiaries for the applicable Excess Cash Flow Offer Determination Period exceeds $2.5 million (the “Excess Cash Flow Offer Threshold”), and to the extent permitted by its Credit Facilities, PES will make an offer in cash in an amount equal to the Excess Cash Flow Offer Amount to purchase Notes (an “Excess Cash Flow Offer”) at an offer price equal to 100% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase (the “Excess Cash Flow Offer Payment”). If the aggregate principal amount of Notes tendered in such Excess Cash Flow Offer exceeds the Excess Cash Flow Offer Amount, the Trustee will select the Notes to be purchased on a pro rata basis, by lot or by such other method as the Trustee deems fair and appropriate. To the extent that the aggregate amount of Notes tendered pursuant to an Excess Cash Flow Offer is less than the Excess Cash Flow Offer Amount, PES may use any remaining Excess Cash Flow Amount for any purpose not otherwise prohibited by the Indenture. Upon completion of any such Excess Cash Flow Offer, the Excess Cash Flow Amount shall be reset at zero; provided that PES will not be deemed to be in default under this covenant for any failure to make an Excess Cash Flow Offer or an Excess Cash Flow Offer Payment by virtue of any adjustment in the amount calculated for any Excess Cash Flow Offer Determination Period due to normal year-end accounting adjustments or other changes concurred in by its public accountants; provided further that any such adjustment in the calculation of the Excess Cash Flow for a prior Excess Cash Flow Offer Determination Period, whether positive or negative, shall be carried forward to the next subsequent Excess Cash Flow Offer Determination Period.

(b) In the event that, pursuant to Section 4.06(a), PES is required to commence an Excess Cash Flow Offer, it will follow the procedures specified below.

(1) Within 100 days following each Determination Date, PES will mail a notice to each Holder and the Trustee offering to repurchase Notes as of the date specified in the notice (the “Excess Cash Flow Offer Purchase Date”), which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed.

(2) The Excess Cash Flow Offer shall be made to all Holders. The Excess Cash Flow 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 “Excess Cash Flow Offer Period”). No later than three Business Days after the termination of the Excess Cash Flow Offer Period, PES will apply the Excess Cash Flow Offer Amount to the purchase of Notes or, if less than the Excess Cash Flow Offer Amount has been tendered, all Notes tendered in response to the Excess Cash Flow Offer.

(3) If the Excess Cash Flow Offer 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 Additional Interest, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no further interest will be payable on such Interest Payment Date to Holders who tender Notes pursuant to the Excess Cash Flow Offer.

(4) Upon the commencement of an Excess Cash Flow Offer, PES will send, by first class mail (or transmit otherwise in accordance with the procedures of DTC), 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 Excess Cash Flow Offer. The notice, which will govern the terms of the Excess Cash Flow Offer, will state:

(A) the CUSIP number;

(B) that the Excess Cash Flow Offer is being made pursuant to this Section 4.06, and the length of time the Excess Cash Flow Offer will remain open;

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

(E) that, unless PES defaults in making such payment, any Note accepted for payment pursuant to the Excess Cash Flow Offer will cease to accrete or accrue interest on and after the Excess Cash Flow Offer Purchase Date;

(F) that Holders electing to have a Note purchase pursuant to an Excess Cash Flow Offer may elect to have Notes purchased in initial denominations of $2,000 and integral multiples of $1,000 in excess thereof;

(G) that Holders electing to have Notes purchased pursuant to any Excess Cash Flow 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 PES, a Depositary, if appointed by PES, or a Paying Agent at the address specified in the notice at least three days before the Excess Cash Flow Offer Purchase Date;

(H) that Holders will be entitled to withdraw their election if PES, the Depositary or the Paying Agent, as the case may be, receives, not later than the close of business on the second Business Day preceding the Excess Cash Flow Offer Purchase Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes delivered for purchase, and a statement that such Holder is withdrawing its election to have such Note purchased;

(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), which unpurchased portion must be equal to $2,000 in principal amount or integral multiples of $1,000 in excess thereof.

(5) On or before the Excess Cash Flow Offer Purchase Date, PES will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Excess Cash Flow Offer Amount of Notes or portions thereof tendered pursuant to the Excess Cash Flow Offer, or if less than the Excess Cash Flow 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 PES in accordance with the terms of this Section 4.06. PES, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Excess Cash Flow Offer 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 PES for purchase, and PES will promptly issue a new Note, and the Trustee, upon written request from PES, 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 PES to the Holder thereof.

(6) PES will notify the Trustee and Holders of the Notes of the results of the Excess Cash Flow Offer as soon as practicable after the Excess Cash Flow Offer Purchase Date.

Section 4.07 Restricted Payments.

(a) PES 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 PES’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving PES or any of its Restricted Subsidiaries) or to the direct or indirect Holders of PES’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 PES and other than dividends or distributions payable to PES or a Restricted Subsidiary of PES);

(2) purchase, redeem, defease or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving PES) any Equity Interests of PES (other than Equity Interests of PES held by a Restricted Subsidiary that is a Guarantor);

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, any Indebtedness of PES or any Guarantor that is contractually subordinated to the Notes or to any Note Guarantee (excluding any intercompany Indebtedness between or among PES and any of its Restricted Subsidiaries), except a payment of interest or principal at the Stated Maturity thereof; or

(4) make any Restricted Investment (all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as “Restricted Payments”),

unless, at the time of and after giving effect to such Restricted Payment:

(1) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment; and

(2) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by PES and its Restricted Subsidiaries since the Issue Date (excluding Restricted Payments permitted by Section 4.07(b)(2) through (7)), is less than the sum, without duplication, of:

(A) 50% of the Consolidated Net Income of PES for the period (taken as one accounting period) from the beginning of the first fiscal quarter commencing after the Issue Date to the end of PES’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus

(B) 100% of the aggregate net cash proceeds received by PES since the Issue Date as a contribution to its common equity capital or from the issue or sale of Equity Interests of PES (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of PES that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of PES); plus

(C) to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or otherwise liquidated or repaid for cash, the lesser of (i) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (ii) the initial amount of such Restricted Investment; plus

(D) to the extent that any Unrestricted Subsidiary of PES designated as such after the Issue Date is redesignated as a Restricted Subsidiary after the Issue Date, the lesser of (i) the Fair Market Value of PES’s Investment in such Subsidiary as of the date of such redesignation or (ii) such Fair Market Value as of the date on which such Subsidiary was originally designated as an Unrestricted Subsidiary after the Issue Date; plus

(E) 50% of any dividends received by PES or a Restricted Subsidiary of PES that is a Guarantor after the Issue Date from an Unrestricted Subsidiary of PES, to the extent that such dividends were not otherwise included in the Consolidated Net Income of PES for such period.

(b) So long as no Default has occurred and is continuing or would be caused thereby, Section 4.07(a) will not prohibit:

(1) the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend or redemption payment would have complied with the provisions of this Indenture;

(2) the making of any Restricted Payment in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of PES) of, Equity Interests of PES (other than Disqualified Stock) or from the substantially concurrent contribution of common equity capital to PES; provided, that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded from clause (2)(b) of the preceding paragraph;

(3) the repurchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness of PES or any Guarantor that is contractually subordinated to the Notes or to any Note Guarantee with the net cash proceeds from a substantially concurrent incurrence of Permitted Refinancing Indebtedness;

(4) a Restricted Payment to pay for the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of PES or any Restricted Subsidiary of PES held by any former officer, director or employee of PES or any of its Restricted Subsidiaries pursuant to any equity subscription agreement, stock option agreement, shareholders’ agreement or similar agreement; provided, that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $1.0 million in any twelve-month period;

(5) the repurchase of Equity Interests deemed to occur upon the exercise of stock options to the extent such Equity Interests represent a portion of the exercise price of those stock options;

(6) [Reserved];

(7) other Restricted Payments in an aggregate amount not to exceed $3.0 million since the Issue Date; and

(8) a payment of a sponsor fee to Layton Corporation equal to 1% of the proceeds of the offering, not to exceed $1.8 million;

provided, however, that if a Liquidity Event has not occurred on or before the date that is 18 months following the Issue Date, neither PES nor any Restricted Subsidiary shall pay dividends or consummate any irrevocable redemption to holders of any class or series of Capital Stock of PES from such date until the date a Liquidity Event occurs.

(c) The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by PES or such Restricted Subsidiary, as the case may be, pursuant to the

Restricted Payment. The Fair Market Value of any assets or securities that are required to be valued by this Section 4.07 will be determined by the Board of Directors of PES whose resolution with respect thereto will be delivered to the Trustee. The Board of Directors’ determination must be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing if the Fair Market Value exceeds $15.0 million. For purposes of determining compliance with this Section 4.07, if a Restricted Payment meets the criteria of more than one of the exceptions described in clauses (1) through (8) above or is entitled to be made pursuant to Section 4.07(a), PES may, in its sole discretion, classify the Restricted Payment in any manner that complies with this Section 4.07.

Section 4.08 Dividend and Other Payment Restrictions Affecting Subsidiaries.

(a) PES will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on its Capital Stock to PES or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any Indebtedness owed to PES or any of its Restricted Subsidiaries;

(2) make loans or advances to PES or any of its Restricted Subsidiaries; or

(3) sell, lease or transfer any of its properties or assets to PES or any of its Restricted Subsidiaries.

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

(1) agreements governing Existing Indebtedness as in effect on the Issue Date and Credit Facilities and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements, provided, that the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the Issue Date (as determined in good faith by the Board of Directors);

(2) the Indenture Documents;

(3) applicable law, rule, regulation or order;

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by PES or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred or issued in connection with or in contemplation 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; provided, that

in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(5) customary non-assignment provisions in contracts and licenses entered into in the ordinary course of business;

(6) purchase money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that impose restrictions on the property purchased or leased of the nature described in Section 4.08(a)(3);

(7) any agreement for the sale or other disposition of a Restricted Subsidiary of PES that restricts distributions, loans or advances by that Restricted Subsidiary pending the sale or other disposition;

(8) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being extended, renewed, refunded, refinanced, defeased or discharged (as determined in good faith by the Board of Directors of PES);

(9) Liens permitted to be incurred under the provisions of Section 4.12 that limit the right of the debtor to dispose of the assets subject to such Liens;

(10) provisions limiting the disposition or distribution of assets or property or equity interests in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into (a) in the ordinary course of business or (b) with the approval of PES’s Board of Directors, which limitation is applicable only to the assets that are the subject of such agreements;

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

(12) any instrument governing Indebtedness of a Foreign Subsidiary; provided, that such Indebtedness was permitted by the terms of this Indenture to be incurred.

Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock.

(a) PES 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”) any Indebtedness (including Acquired Debt), and PES will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any Disqualified Stock or shares of preferred stock.

(b) The provisions of Section 4.09(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

(1) the incurrence by PES and its Restricted Subsidiaries of Indebtedness and letters of credit under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit under Credit Facilities being deemed to have a principal amount equal to the maximum potential liability of PES and its Restricted Subsidiaries thereunder) not to exceed $15.0 million, less the aggregate amount of all Net Proceeds of Asset Sales applied by PES or any of its Restricted Subsidiaries since the Issue Date to repay any term Indebtedness under a Credit Facility classified under this clause (1) or to repay any revolving credit Indebtedness under such Credit Facility and effect a corresponding commitment reduction thereunder pursuant to Section 4.10;

(2) the incurrence by PES and the Guarantors of Indebtedness represented by the Notes and the related Note Guarantees to be issued on the Issue Date and the exchange of Notes and the related Note Guarantees to be issued pursuant to the Registration Rights Agreement (other than any Additional Notes);

(3) the incurrence by PES and its Restricted Subsidiaries of the Existing Indebtedness (other than the Indebtedness described in clauses (1) and (2));

(4) the incurrence by PES 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 (real or personal), plant or equipment used in the business of PES or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed $5.0 million at any time outstanding;

(5) the incurrence by PES or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(b)(2),(3), (4), (5) or (7);

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

(a) if PES or any Guarantor is the obligor on such Indebtedness and the payee is not PES or a Guarantor, 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 of PES, or the Note Guarantee, in the case of a Guarantor; and

(b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than PES or a Restricted

Subsidiary of PES and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either PES or a Restricted Subsidiary of PES

will be deemed, in each case, to constitute an incurrence of such Indebtedness by PES or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) on or after September 1, 2011, the incurrence by PES or any of its Restricted Subsidiaries of Indebtedness not to exceed $35 million in aggregate principal amount; provided that such Indebtedness is used by PES or any of its Restricted Subsidiaries solely for the purpose of acquiring equipment;

(8) the incurrence by PES or any of its Restricted Subsidiaries of Hedging Obligations (excluding Hedging Obligations entered into for speculative purposes) in the ordinary course of business solely for the purpose of limiting:

(a) interest rate risk with respect to any Indebtedness permitted to be incurred pursuant to this Section 4.09;

(b) exchange rate risk with respect to any currency exchange;

(d) any combination of the foregoing;

(9) (a) the Guarantee by PES or any of the Guarantors of Indebtedness of a Restricted Subsidiary of PES so long as the incurrence of such Indebtedness incurred by such Restricted Subsidiary is permitted under the terms of this Indenture; or

(b) the Guarantee by a Restricted Subsidiary of PES of Indebtedness of PES or another Restricted Subsidiary so long as the incurrence of such Indebtedness incurred by such Restricted Subsidiary is permitted under the terms of this Indenture;

provided, in each case, that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the Note Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed;

(10) the incurrence by PES or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation, general liability or truckers’ liability claims, payment obligations in connection with health or other types of social security benefits, unemployment or other insurance or self-insurance obligations, insurance premium finance agreements, statutory obligations, bankers’ acceptances and performance, appeal or surety bonds in the ordinary course of business;

(11) the incurrence by PES or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; and

(12) the incurrence of Indebtedness consisting of indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or a Subsidiary in accordance with the terms of this Indenture, other than Indebtedness or guarantees of Indebtedness incurred or assumed by any Person acquiring all or any portion of such business, assets or Subsidiary for the purpose of financing such acquisition.

(c) For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (12) above, PES will be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. The accrual of interest, 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, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual, accretion or payment (without duplication) is included in Fixed Charges of PES as accrued. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that PES 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.

(d) The amount of any Indebtedness outstanding as of any date will be:

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(a) the Fair Market Value of such assets at the date of determination; and

(b) the amount of the Indebtedness of the other Person.

(e) PES will not incur, and will not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of PES or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of PES solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis.

Section 4.10 Asset Sales.

(a) PES will not, and will not permit any of its Restricted Subsidiaries to, cause, make or suffer to exist an Asset Sale (it being understood that sales of all or substantially all of the assets of PES and its Restricted Subsidiaries will be governed by Section 5.01) unless:

(1) PES (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received in the Asset Sale by PES or such Restricted Subsidiary 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 PES’s most recent consolidated balance sheet, of PES or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases PES or such Restricted Subsidiary from further liability; and

(B) any securities, notes or other obligations received by PES or any such Restricted Subsidiary from such transferee that are within 60 days, subject to ordinary settlement periods, converted by PES or such Restricted Subsidiary into cash or Cash Equivalents, to the extent of the cash received in that conversion; and

(b) Within 360 days after the receipt of any Net Proceeds from an Asset Sale, PES (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds:

(1) to repay Indebtedness and other Obligations under a Credit Facility or the Morgan Stanley Facility and to the extent such Indebtedness is in the form of a revolving facility, to correspondingly reduce commitments with respect thereto;

(2) to acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted Business, if, after giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of PES;

(3) to make a capital expenditure; or

(4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business.

(c) Any stock or assets deemed to be cash pursuant to Section 4.10(a)(2)(C) are deemed acquired with Net Proceeds equal to the deemed cash amount. Pending the final application of any Net Proceeds, PES may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

(d) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(b) will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $5.0 million, PES will, within 30 days thereof, make one or more Asset Sale Offers to the Holders of the Notes (and, at the option of PES, the holders of Other Pari Passu Obligations) to purchase Notes (and Other Pari Passu Obligations) pursuant to and subject to the conditions contained in this Indenture (each, an “Asset Sale Offer”), that are $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to, but not including, the date fixed for the closing of such offer, in accordance with the procedures set forth in Section 3.09, of this Indenture. PES will commence an Asset Sale Offer with respect to Excess Proceeds within 30 days after the date that Excess Proceeds exceeds $5.0 million by mailing (or transmitting otherwise in accordance with the procedures of DTC), the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. To the extent that the aggregate amount of Notes and such Other Pari Passu Obligations tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, PES may use any remaining Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes or the Other Pari Passu Obligations surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Notes and such Other Pari Passu Obligations will be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Other Pari Passu Obligations tendered. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

(e) PES 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 the Asset Sale provisions of this Indenture, PES will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of this Indenture by virtue of such compliance.

Section 4.11 Transactions with Affiliates.

(a) PES will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, 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 arms-length transaction, or series of related transactions, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of PES (each, an “Affiliate Transaction”), unless:

(1) the Affiliate Transaction is on terms that are not less favorable to PES or the relevant Restricted Subsidiary (as determined in good faith by the Board of Directors

of PES) than those that would have been obtained in a comparable transaction by PES or such Restricted Subsidiary with an unrelated Person; and

(2) PES delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $5.0 million, a resolution of the Board of Directors of PES set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with this Section 4.11 and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of PES; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $15.0 million, an opinion as to the fairness to PES or such Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing.

(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) hereof:

(1) any employment, service, termination, or consulting agreement, employee benefit plan, officer or director indemnification agreement or any similar arrangement entered into by PES or any of its Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto;

(2) transactions between or among PES and/or its Restricted Subsidiaries;

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

(4) the payment of reasonable directors’ fees, the payments of other reasonable benefits and the provision of officers’ and directors’ indemnification and insurance to the extent permitted by law to persons who are officers and directors of PES and its Restricted Subsidiaries, in each case in the ordinary course of business and approved by the Board of Directors;

(5) any issuance of Equity Interests (other than Disqualified Stock) of PES to Affiliates of PES;

(6) Restricted Payments that do not violate Section 4.07;

(7) transactions effected pursuant to agreements in effect on the Issue Date and described in the Offering Circular and any amendment, modification or replacement of such agreement (so long as such amendment or replacement is not less favorable to PES, any Restricted Subsidiary or the Holders, taken as a whole, than the original

agreement as in effect on the Issue Date as determined in good faith by the Board of Directors of PES);

(8) loans or advances to employees in the ordinary course of business not to exceed $1.0 million in the aggregate at any one time outstanding; and

(9) purchases of the Units by Affiliates of PES.

Section 4.12 Liens.

PES will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind on any asset now owned or hereafter acquired, except Permitted Liens.

Section 4.13 Business Activities.

PES will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses, except to such extent as would not be material to PES and its Restricted Subsidiaries taken as a whole.

Section 4.14 Corporate Existence.

Subject to Article 5 hereof, PES shall do or cause to be done all things necessary to preserve and keep in full force and effect:

(1) its corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of PES or any such Subsidiary; and

(2) the rights (charter and statutory), licenses and franchises of PES and its Subsidiaries;

provided, however, that PES shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if PES shall determine that the preservation thereof is no longer desirable in the conduct of the business of PES and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.15 Offer to Repurchase Upon Change of Control.

(a) If a Change of Control occurs, each Holder of Notes will have the right to require PES to offer to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”) at a price in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Additional Interest, if any, on the Notes repurchased to, but not including, the date of purchase, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control, PES will mail

such Change of Control Offer by first class mail, with a copy to the Trustee, to each Holder of Notes to the address of such Holder appearing in the security register or otherwise in accordance with the procedures of DTC, with the following information:

(1) a Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes properly tendered pursuant to such Change of Control Offer will be accepted for payment;

(2) the purchase price and the purchase date, which will be no earlier than 30 days nor later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”);

(3) any Note not properly tendered will remain outstanding and continue to accrue interest;

(4) unless PES defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on, but not including, the Change of Control Payment Date;

(5) 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” on the reverse of the Notes completed, to the Paying Agent specified in the notice at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6) Holders will be entitled to withdraw their tendered Notes and their election to require PES to purchase such Notes; provided, that the Paying Agent receives, not later than the close of business on the last day of the offer period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased;

(7) if such notice is mailed prior to the occurrence of a Change of Control, stating the Change of Control Offer is conditional on the occurrence of such Change of Control; and

(8) 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 or an integral multiple of $1,000 in excess thereof.

(b) While the Notes are in global form and PES makes an offer to purchase all or any portion of the Notes pursuant to the Change of Control Offer, a Holder may exercise its option to elect for the purchase of the Notes through the facilities of DTC, subject to its rules and regulations.

(c) PES 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 pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15, PES will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such compliance.

(d) On the Change of Control Payment Date, PES will, to the extent permitted by law:

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

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

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

(e) The Paying Agent will promptly mail to each Holder of Notes properly tendered and so accepted the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered by each such Holder, if any; provided, that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Any Note so accepted for payment will cease to accrue interest on and after the Change of Control Payment Date. PES will notify the Trustee and Holders of the Notes of the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(f) The provisions described above that require PES to make a Change of Control Offer following a Change of Control will be applicable whether or not any other provisions of this Indenture are applicable. Except as described in this Section 4.15 with respect to a Change of Control, the Holders of the Notes may not require PES to repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

(g) PES will not be required to make a Change of Control Offer following a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by PES and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.07 unless and until there is a default in payment of the applicable redemption price. Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control.

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

(i) The provisions under this Indenture relative to PES’s obligation to make an offer to repurchase the Notes as a result of a Change of Control may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes.

Section 4.16 Additional Note Guarantees.

If PES or any of its Restricted Subsidiaries acquires or creates another Domestic Subsidiary after the Issue Date, then PES will (1) cause that newly acquired or created Domestic Subsidiary to (a) execute a supplemental Indenture pursuant to which it becomes a Guarantor and (b) execute an amendment to the Registration Rights Agreement pursuant to which it becomes subject to the obligations of a Guarantor thereunder, (2) cause the newly acquired or created Domestic Subsidiary to execute and deliver to the Trustee and the Collateral Agent amendments to the Security Documents or additional Security Documents and take such other action as may be necessary to grant to the Collateral Agent, for the benefit of the Holders, a perfected Lien in the assets other than Excluded Assets of such Domestic Subsidiary, including the filing of UCC financing statements in such jurisdiction or such other actions as may be required by the Security Documents, (3) cause that newly acquired or created Domestic Subsidiary to take such actions necessary or as the Collateral Agent reasonably determines to be advisable to grant to the Collateral Agent for the benefit of the Holders a perfected Lien in the assets other than Excluded Assets of such new Domestic Subsidiary, including the filing of UCC financing statements in such jurisdiction as may be required by the Security Documents or by law or as may be reasonably requested by the Collateral Agent, (4) cause that newly acquired or created Domestic Subsidiary to take such further action and execute and deliver such other documents reasonably requested by the Trustee or the Collateral Agent to effectuate the foregoing, and (5) deliver an Opinion of Counsel with respect to the foregoing reasonably satisfactory to the Trustee, in each case, within 30 Business Days of the date on which the Domestic Subsidiary was acquired or created.

Section 4.17 Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of PES may designate any Subsidiary (including any newly acquired or newly formed Subsidiary or Person that becomes a Subsidiary through merger or consolidation or Investment therein) 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 PES 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 PES. 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. The Board of Directors of PES may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default.

Any designation of a Subsidiary of PES 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 giving effect to such designation and an Officers’ Certificate certifying that such designation

complied with the preceding conditions and was permitted by 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 of PES as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09, PES will be in default of such covenant. The Board of Directors of PES may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of PES; provided, that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of PES 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 four-quarter reference period; and (2) no Default or Event of Default would be in existence following such designation.

Section 4.18 Impairment of Security Interest

Subject to an Intercreditor Agreement, neither PES nor any of its Restricted Subsidiaries will take or omit to take any action which would adversely affect or impair in any material respect the Liens in favor of the Collateral Agent with respect to the Collateral, except as otherwise permitted or required by the Security Documents or this Indenture. Neither PES nor any of its Restricted Subsidiaries will enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness of any Person, other than the First Lien Obligations and any other Obligations which are secured by a Permitted Lien that is senior to the Lien securing the Second Lien Obligations, the Notes and the Security Documents, unless such agreement permits PES or such Restricted Subsidiary to first repay, or offer to repay, First Lien Obligations and the Notes. PES shall, and shall cause each Guarantor to, at its sole cost and expense, execute and deliver all such agreements and instruments as the Collateral Agent or the Trustee shall reasonably request to more fully or accurately describe the property intended to be Collateral or the obligations intended to be secured by the Security Documents. PES shall, and shall cause each Guarantor to, at its sole cost and expense, file any such notice filings or other agreements or instruments as may be reasonably necessary or desirable under applicable law to perfect the Liens created by the Security Documents at such times and at such places as the Collateral Agent or the Trustee may reasonably request.

Section 4.19 Post-Closing

Certain security interests in the Collateral may not be in place on the Issue Date or may not be perfected on the Issue Date. PES and the Guarantors will use their respective commercially reasonable efforts to perfect on the Issue Date the security interests in the Collateral for the benefit of the Holders of the Notes and the First Lien Obligations, if any, that are created on the Issue Date but, to the extent any such security interest or liens are not perfected by such date, PES and the Guarantors will agree to do or cause to be done all acts and things that may be required, including obtaining any required consents from third parties, to have all security interests in the Collateral duly created and enforceable and perfected, in each case solely to the extent required by the Security Documents, promptly following the Issue Date, but in any event no later than the date 90 days thereafter. In addition, the Security Documents may

not require that all Collateral be perfected if such Collateral cannot be perfected by the filing of UCC financing statements or the recording of mortgages or deeds of trust.

Section 4.20 Further Assurances

PES and the Guarantors shall execute any and all further documents, financing statements, agreements and instruments, and take all further action that may be required under applicable law, or that the Collateral Agent may reasonably request, in order to grant, preserve, protect and perfect the validity and priority of the security interests created or intended to be created by the Security Documents in the Collateral. In addition, from time to time, PES will reasonably promptly secure the Obligations under this Indenture and the Security Documents by pledging or creating, or causing to be pledged or created, perfected security interests with respect to the Collateral. PES shall deliver or cause to be delivered to the Collateral Agent all such instruments and documents as the Collateral Agent shall reasonably request to evidence compliance with this Section 4.20.

Section 4.21 Real Estate Mortgages and Filings

With respect to any real property other than Excluded Real Property (individually and collectively, the “Premises”) owned by PES or a Domestic Subsidiary (other than Unrestricted Subsidiaries) on the Issue Date and with respect to any such property to be acquired by PES or a Domestic Subsidiary (other than Unrestricted Subsidiaries) after the Issue Date (within 90 days of the acquisition thereof):

(1) PES shall deliver to the Collateral Agent, as mortgagee, fully executed counterparts of Mortgages, duly executed by PES or the applicable Domestic Subsidiary, together with evidence of the completion (or satisfactory arrangements for the completion) of all recordings and filings of such Mortgage as may be necessary to create a valid, perfected Lien, subject to Permitted Liens, against the properties purported to be covered thereby;

(2) PES shall deliver to the Collateral Agent mortgagee’s title insurance policies in favor of the Collateral Agent, as mortgagee for the ratable benefit of the Collateral Agent, the Trustee and the Holders in an amount equal to 100% of the Fair Market Value of the Premises purported to be covered by the related Mortgage, insuring that title to such property is marketable and that the interests created by the Mortgage constitute valid Liens thereon free and clear of all Liens, defects and encumbrances other than Permitted Liens together with customary endorsements, coinsurance and reinsurance typical for the applicable jurisdiction;

(3) PES shall deliver to the Collateral Agent, to the extent provided to any First Lien Agent, with respect to each of the covered Premises, the most recent survey of such Premises prepared on or on behalf of PES, together with either (i) an updated survey certification in favor of the Trustee and the Collateral Agent from the applicable surveyor stating that, based on a visual inspection of the property and the knowledge of the surveyor, there has been no change in the facts depicted in the survey or (ii) an affidavit

from PES stating that there has been no change sufficient for the title insurance company to remove all standard survey exceptions and issue the customary endorsements; and

(4) PES shall deliver an opinion(s) of counsel of PES confirming that the Mortgages and Security Documents create a Lien on the Premises purported to be covered by the related Mortgage, which shall be from local counsel in each state where a Premises is located covering the enforceability of the relevant Mortgages;

in each case, using commercially reasonable efforts to comply with the foregoing by the Issue Date but, in any event, no later than 90 days thereafter.

Section 4.22 Leasehold Mortgages and Filings; Landlord Waivers

PES and each of its Domestic Subsidiaries (other than any Unrestricted Subsidiary) shall use commercially reasonable efforts to deliver Mortgages with respect to PES’s leasehold interests in any premises material to the business taken as a whole (the “Leased Premises”) (other than Excluded Real Property) occupied by PES or such Domestic Subsidiary (other than any Unrestricted Subsidiary) pursuant to leases which may be mortgaged by their terms or the terms of the landlord consents (collectively, the “Leases,” and individually, a “Lease”) in each case using commercially reasonable efforts to comply with the foregoing by the Issue Date but, in any event, no later than 90 days thereafter.

With respect to any leasehold Mortgage delivered pursuant to the immediately preceding paragraph, PES or the applicable Subsidiary shall provide to the Trustee all of the items described in Section 4.21(2), 4.21(3) and 4.21(4) above and in addition shall use their respective commercially reasonable efforts to obtain an agreement executed by the lessor under the Lease, whereby the lessor consents to the Mortgage and waives or subordinates its landlord Lien (whether granted by the instrument creating the leasehold estate or by applicable law), if any, and which shall be entered into by the Collateral Agent, subject to its reasonable satisfaction of the form thereof.

Each of PES and each of its Domestic Subsidiaries that is a lessee of, or becomes a lessee of, real property (other than Excluded Real Property) material to the business, is, and will be, required to use commercially reasonable efforts to deliver to the Collateral Agent a landlord waiver, in the form reasonably acceptable to the Collateral Agent executed by the lessor of such real property (other than Excluded Real Property); provided, that in the case where such lease is a lease in existence on the Issue Date, PES or its Domestic Subsidiary that is the lessee thereunder shall have 90 days from the Issue Date to satisfy such requirement.

Section 4.23 Advances to Subsidiaries

All advances to Restricted Subsidiaries made by PES after the Issue Date will be evidenced by intercompany notes in favor of PES. These intercompany notes will be pledged pursuant to the Security Documents as Collateral to secure the Notes. Each intercompany note will be payable upon demand and will be subordinated in right of payment to all existing Senior Debt of the Restricted Subsidiary to which the loan is made. “Senior Debt” of Subsidiaries for the purposes of the intercompany notes will be defined as all Indebtedness of the Restricted

Subsidiaries that is not specifically by its terms made pari passu with or junior to the intercompany notes.

PES will not permit any Restricted Subsidiary in respect of which PES is a creditor by virtue of an intercompany note to incur any Indebtedness that is subordinate or junior in right of payment to any Senior Debt of such Restricted Subsidiary and senior in any respect in right of payment to any intercompany note.

Section 4.24 Maximum Capital Expenditures

PES and its Restricted Subsidiaries will not allow aggregate Capital Expenditures in any one fiscal year (which amount shall be prorated in the case of the first fiscal year following the Issue Date) to exceed $10 million (the “Capex Limit”); provided that, to the extent the aggregate Capital Expenditures in any one fiscal year are less than the Capex Limit, then PES and its Restricted Subsidiaries may carry forward such unused amounts to be applied in subsequent fiscal years; and provided further that (i) $113 million in anticipated expenditures for new equipment (as set forth under “Use of Proceeds” in the Offering Circular), (ii) additional equipment purchases permitted pursuant to Section 4.09(b) (7) (iii) the acquisition of WSB or its assets as contemplated by the Lease Purchase Agreement, and (iv) Capital Expenditures made with any Remaining Amount or the net cash proceeds of any Equity Offering shall not be counted for purposes of the Capex Limit. All Capital Expenditures shall first be applied to reduce the carry-forward from the previous fiscal year (or portion thereof), if any, and then to reduce the applicable Capex Limit for the current year.

Section 4.25 Board Observer

(a) For so long as any Notes are outstanding, Holders of a majority of the principal amount of Notes shall have the right to elect one board observer to the Board of Directors at their sole discretion in accordance with the procedures set forth in this Section 4.25.

(b) Unless otherwise directed in writing by Holders of a majority of the principal amount of the Notes then outstanding voting as a single class, no later than 90 days after the Issue Date, PES will mail or cause to be mailed by first class mail (or transmitted otherwise in accordance with the procedures of DTC), a notice to each Holder. The notice will (i) announce the solicitation of nominees to act as board observer on behalf of Holders and (ii) provide, in reasonable detail, an explanation of the procedures to be followed for the election of the board observer, which such explanation shall provide, at a minimum:

(1) the identity, powers and responsibilities of an officer of election with respect to the board observer;

(2) that Holders shall have the right to nominate candidates to the position of board observer;

(3) that PES shall, at its own expense, mail to Holders reasonably detailed professional biographical information (to the extent provide such information is provided to or available to PES) of each such nominee;

(4) that Holders shall have the right to participate in the election of the board observer via mail, facsimile, electronic voting or other similar methodology;

(5) the proposed method for communication to all Holders of the results of such election, including current contact information of the board observer.

(c) The initial board observer designated by the Holders shall serve until such time as such person (i) resigns, (ii) is removed by Holders of a majority of the principal amount of Notes or (iii) a new board observer is designated in writing or elected by Holders of a majority of the principal amount of Notes. In the case of a board observer’s resignation, a new board observer shall be designated in writing or elected by Holders of a majority of the principal amount of Notes pursuant to Section 4.25(b) above.

(d) The Trustee shall have no responsibility for administering or facilitating such procedure, nor shall the Trustee be charge with knowledge of such election, except upon notice to the Trustee of PES’s failure to comply with the provisions of this Section 4.25 by Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class.

(e) The board observer shall be a non-voting observer to the Board of Directors. PES will provide to the board observer, at the same time as PES provides such materials to the directors, a copy of all notices and materials sent to the directors. The Board of Directors, by majority vote, may exclude the board observer from any meeting, or withhold any materials, if the board observer’s access to such meeting or materials would cause PES to violate confidentiality undertakings towards a third party or to waive the attorney-client privilege.

Section 4.26 Officers’ Certificate

In connection with each purchase of, or interim payment towards the purchase of, Core Operating Equipment in excess of $1 million, PES shall provide the Trustee with an Officers’ Certificate, in the form and manner provided in this Indenture, certifying (a) that such purchase or payment has been made, (b) the amount paid in connection therewith, and (c) (i) that, based on the reasonable belief of such Officers, the Core Operating Equipment will be delivered in accordance with the delivery schedule and purchase price for such Core Operating Equipment as described in the Offering Circular, or if the certification described in this clause (c) cannot be made, (ii) PES will provide a reasonably detailed explanation for any such delay in such delivery schedule or increase in such purchase price. PES shall provide Holders and holders of Units or Warrants, as applicable, with such information.

(8) except as permitted by this Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases 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;

(9) (x) any Security Document at any time for any reason shall cease to be in full force and effect in all material respects, except as expressly provided therein; (y) any Security Document ceases to give the Collateral Agent the Liens, rights, powers and privileges purported to be created thereby with respect to any Collateral having a Fair Market Value in excess of $1.0 million, superior to and prior to the rights of all third Persons other than the holders of Permitted Liens and subject to no other Liens except as expressly permitted by the applicable Security Document or this Indenture; or (z) PES or any of the Guarantors, directly or indirectly, contest in any manner the effectiveness, validity, binding nature or enforceability of any Security Document;

(A) commences a voluntary case under any Bankruptcy Law;

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

(D) makes a general assignment for the benefit of its creditors, or

Section 6.02 Acceleration.

(a) In the case of an Event of Default described in Section 6.01(10) or (11) with respect to PES, any Restricted Subsidiary of PES that is a Significant Subsidiary or any group of Restricted Subsidiaries of PES that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. 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.

(b) Subject to Section 6.05 and Section 6.06, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal, interest or premium or Additional Interest, if any, on the Notes. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of all the Holders of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of principal, interest or premium or Additional Interest, if any, on the Notes.

(c) In the case of any Event of Default occurring by reason of any willful action (or inaction) taken (or not taken) by or on behalf of PES with the intention of avoiding payment of the premium that PES would have had to pay if PES then had elected to redeem the Notes pursuant to the optional redemption provisions of this Indenture, an equivalent premium will also become and be immediately due and payable to the extent permitted by law upon the acceleration of the Notes. If an Event of Default occurs prior to March 1, 2013, by reason of any willful action (or inaction) taken (or not taken) by or on behalf of PES with the intention of avoiding the prohibition on redemption of the Notes prior to March 1, 2013, then the premium otherwise required to be paid under Section 3.07(c) herein will also become and be immediately due and payable to the extent permitted by law upon the acceleration of the Notes.

Section 6.03 Other Remedies.

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

(b) 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.

Section 6.04 Waiver of Past Defaults.

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

Section 6.05 Control by Majority.

(a) 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, except as otherwise provided in this Indenture. 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.

(b) Subject to this Section 6.05 and Section 6.06, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold notice of any continuing Default or Event of Default from Holders of the Notes if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal of, or interest, premium or Additional Interest, if any, on, the Notes.

Section 6.06 Limitation on Suits.

Subject to the provisions of this Indenture and the Security Documents relating to the duties of the Trustee and the Collateral Agent, in case an Event of Default occurs and is continuing, neither the Trustee nor the Collateral Agent will be under any obligation to exercise any of the rights or powers under this Indenture or any Security Document at the request or direction of any Holders of Notes unless such Holders have offered to the Trustee or the

Collateral Agent, as the case may be, reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, interest or premium or Additional Interest, if any, when due, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless:

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

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes have requested the Trustee to pursue the remedy;

(3) such Holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense;

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

(5) Holders of a majority in aggregate principal amount of the then outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period,

provided, that no one or more of such Holders will have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb, or prejudice the rights of any other of such Holders (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and Additional Interest, if any, and interest 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; provided that a Holder shall not have the right to institute any such suit for the enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under applicable law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as Trustee of an express trust against PES for the whole amount of principal of, premium and Additional Interest, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest 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.

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 pursuant to Section 7.07 hereof 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.

Section 6.10 Priorities.

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 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

ARTICLE 7

TRUSTEE

Section 7.01 Duties of Trustee.

(a) If an Event of Default occurs and is continuing, the Trustee will exercise such of the rights and powers vested in it by this Indenture, to use the same degree of care and skill in its exercise as that of a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

(b) Except during the continuance of an Event of Default:

(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 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; but in the case of any such certificates or opinions by which any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(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 hereof.

(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) 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 and powers under this Indenture at the request of any Holder, unless such Holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.

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

Section 7.02 Rights of Trustee.

(a) The Trustee may conclusively rely upon any document 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, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if an Event of Default has occurred and is continuing, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of PES, personally or by agent or attorney at the sole cost of PES and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(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) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from PES will be sufficient if evidenced by an Officers’ Certificate.

(e) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders

have offered to the Trustee reasonable indemnity or security against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.

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

(h) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

(i) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee and by the Collateral Agent in each of its capacities hereunder, under the Security Documents and under the Intercreditor Agreement, and each agent, custodian and other Person employed to act hereunder.

(j) In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

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

Section 7.03 Individual Rights of Trustee.

If the Trustee becomes a creditor of PES or any Guarantor, this Indenture limits the right of the Trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; however, if it 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.

Section 7.04 Trustee’s Disclaimer.

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 PES’s use of the proceeds from the Notes or any money paid to PES or upon PES’s 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.

Section 7.05 Notice of Defaults.

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

Section 7.06 Reports by Trustee to Holders of the Notes.

(a) If required by the TIA, within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee will mail to the Holders of the 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) if required by the TIA. The Trustee will also transmit by mail all reports as required by TIA § 313(c), if required by the TIA.

(b) If required by the TIA, a copy of each report at the time of its mailing to the Holders of Notes will be mailed by the Trustee to PES and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). PES will promptly notify the Trustee when the Notes are listed on any stock exchange.

Section 7.07 Compensation and Indemnity.

(a) PES will pay to the Trustee and Collateral Agent from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. PES will reimburse the Trustee and Collateral Agent 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) PES 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 PES and the Guarantors (including this Section 7.07) and

defending itself against any claim (whether asserted by PES, 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 or bad faith. Each of the Trustee and Collateral Agent will notify PES promptly of any claim for which it may seek indemnity. Failure by the Trustee or Collateral Agent to so notify PES will not relieve PES or any of the Guarantors of their obligations hereunder. PES or such Guarantor will defend the claim and the Trustee and Collateral Agent will cooperate in the defense. Neither PES nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

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

(d) To secure PES’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee and Collateral Agent 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 and interest on particular Notes.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or (9) hereof 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.

Section 7.08 Replacement of Trustee.

(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 by so notifying PES. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and PES in writing. PES may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.10 hereof;

(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

(4) the Trustee becomes incapable of acting.

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, PES will promptly appoint a successor Trustee. Within one year after the

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 PES.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, PES, 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 hereof, 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 PES. 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 mail 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 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, PES’s obligations pursuant to Section 7.07 hereof will continue for the benefit of the retiring Trustee.

Section 7.09 Successor Trustee by Merger, etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation, if eligible under Section 7.10 hereof, without any further act will be the successor Trustee.

Section 7.10 Eligibility; Disqualification.

There will at all times be a Trustee hereunder that is a corporation 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 $100.0 million as set forth in its most recent published annual report of condition.

Section 7.11 Preferential Collection of Claims Against PES.

Section 7.12 Rights of Agents in Other Capacities

The Trustee, any authenticating agent, any Paying Agent, any Registrar or any other agent of PES, in its individual or any other capacity, may become the owner or pledgee of Notes and, subject to Sections 7.10 and 7.11, may otherwise deal with PES with the same rights it would have if it were not Trustee, authenticating agent, Paying Agent, Registrar or such other agent

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance and Covenant Defeasance.

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

Section 8.02 Legal Defeasance and Discharge.

Upon PES’s exercise pursuant to Section 8.01 hereof of the option applicable to this Section 8.02, PES and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, 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 PES 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 hereof 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, the Security Documents and this Indenture (and the Trustee, on demand of and at the expense of PES, 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, and interest or premium and Additional Interest, if any, on, such Notes when such payments are due from the trust referred to below;

(2) PES’s obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

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

(4) this Article 8.

In addition, PES may, at its option and at any time, elect to have the obligations of PES and the Guarantors released with respect to certain covenants (including its obligation to make Change of Control Offers and Asset Sale Offers) that are described in this Indenture (“Covenant Defeasance”) and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default with respect to the Notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events described in Section 6.01(10) and (11)) will no longer constitute an Event of Default with respect to the Notes.

Section 8.03 Covenant Defeasance.

Upon PES’s exercise pursuant to Section 8.01 hereof of the option applicable to this Section 8.03, PES and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.04, and 4.06 through 4.26 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “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 Guarantees, PES 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 pursuant to Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Guarantees will be unaffected thereby. In addition, upon PES’s exercise pursuant to Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(5) and 6.01(9) hereof will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

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

(1) PES must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the 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, and interest, premium and Additional Interest, 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 PES must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date;

(A) PES has 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 pursuant to Section 8.03 hereof, PES has delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee (subject to customary exceptions and exclusions) 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 or the grant of any Lien securing such borrowing);

(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 the Indenture Documents) to which PES or any of its Subsidiaries is a party or by which PES or any of its Subsidiaries is bound;

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

(7) PES must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

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

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee,

collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof 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 PES 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 and Additional Interest, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

PES 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 hereof 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 PES from time to time upon the request of PES any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered pursuant to Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to PES.

Any money deposited with the Trustee or any Paying Agent, or then held by PES, in trust for the payment of the principal of, premium or Additional Interest, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium or Additional Interest, if any, or interest has become due and payable shall be paid to PES on its request or (if then held by PES) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to PES for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of PES 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 PES 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 PES.

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, 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 PES’s 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 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if PES makes any payment of principal of,

premium or Additional Interest, if any, or interest on, any Note following the reinstatement of its obligations, PES 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.

(c) In addition to the foregoing, Holders of the Notes, by the acceptance thereof, shall be deemed to agree that the Security Documents may be amended without the consent of any Holder or Notes in circumstances set forth in the Intercreditor Agreement.

Section 9.02 With Consent of Holders of Notes.

(a) Except as provided below in this Section 9.02, this Indenture or the Notes or the Note Guarantees or the Security Documents may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or Exchange Offer for, Notes), and any existing Default or Event of Default or compliance with any provision of this Indenture or the Notes or the Note Guarantees or the Security Documents may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or Exchange Offer for, Notes).

(b) Upon the request of PES accompanied by a resolution of its Board 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 Sections 7.02 and 9.06 hereof, the Trustee will join with PES 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.

(c) 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, waiver or consent but it is sufficient if such consent approves the substance thereof.

(d) After an amendment, supplement or waiver under this Section 9.02 becomes effective, PES will mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of PES to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a

100

majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by PES or any Guarantor with any provision of the Indenture Documents. However, without the consent of each Holder affected thereby, 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 any of the provisions with respect to the redemption of the Notes (except with respect to Sections 3.09, 4.06, 4.10 and 4.15 hereof or with respect to the notice provisions set forth in Section 3.07 hereof);

(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, or interest premium or Additional Interest, if any, or interest on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

(5) make any Note payable in money other than that stated in the Notes;

(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, or interest or premium or Additional Interest, if any, on, the Notes;

(7) waive a redemption payment with respect to any Note (other than a payment required by Sections 3.09, 4.06, 4.10 or 4.15 hereof);

(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;

(9) make any change in the preceding amendment, supplement and waiver provisions of this Section 9.02(d); or

(10) make any change in the ranking or priority of the Notes.

(e) In addition, any amendment to, or waiver of, the provisions of this Indenture, any Security Document or the Intercreditor Agreement that has the effect of releasing all or substantially all of the Collateral from the Liens securing the Notes or subordinating Liens securing the Notes (except as permitted by the terms of this Indenture, the Security Documents and the Intercreditor Agreement) will require the consent of the Holders of at least 66²/3% in aggregate principal amount of the Notes then outstanding.

101

Section 9.03 Compliance with Trust Indenture Act.

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.

Section 9.04 Revocation and Effect of Consents.

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.

Section 9.05 Notation on or Exchange of Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. PES 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.

Section 9.06 Trustee to Sign Amendments, etc.

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. PES may not sign an amended or supplemental indenture until the Board of Directors of PES approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 13.04 hereof, 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.

ARTICLE 10

COLLATERAL AND SECURITY

Section 10.01 Grant of Security Interest.

The due and punctual payment of the principal of and interest and Additional Interest, if any, on the Notes when and as the same shall be due and payable, whether on an Interest Payment Date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of and interest and Additional Interest (to the extent permitted by law), if any, on the Notes (including, but not limited to, all interest accrued or accruing (or which would,

102

absent commencement of an Insolvency Proceeding (and the effect of provisions such as Section 502(b)(2) of the Bankruptcy Law), accrue) after commencement of an Insolvency Proceeding, whether or not the claim for such interest is allowed as a claim in such Insolvency Proceeding), and performance of all other obligations of PES and the Guarantors to the Holders or the Trustee under this Indenture and the Notes, according to the terms hereunder or thereunder, shall be secured by all property and assets of PES and the Guarantors that from time to time are subject to Liens securing First Lien Obligations, other than the Excluded Assets, including as provided in the Security Documents which PES and the Guarantors have entered into simultaneously with the execution of this Indenture, in each case subject to the Intercreditor Agreement. Each Holder, by its acceptance of Notes, consents and agrees to the terms of the Intercreditor Agreement and the other Security Documents (including, without limitation, the provisions providing for foreclosure and release of Collateral) as the same may be in effect or may be amended, waived, supplemented or modified from time to time in accordance with its terms and authorizes and directs the Collateral Agent to enter into the Intercreditor Agreement and the other Security Documents and to perform its obligations and exercise its rights thereunder in accordance therewith. PES will deliver to the Trustee copies of all documents delivered to the Collateral Agent pursuant to the Security Documents, and will do or cause to be done all such acts and things as may be necessary or proper, or as may be required by the provisions of the Security Documents, to assure and confirm to the Trustee and the Collateral Agent the security interest in the Collateral contemplated hereby, by the Security Documents or any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this Indenture and of the Notes secured hereby, according to the intent and purposes herein expressed. The Collateral Agent may open and maintain one or more accounts to hold the Collateral and the Security Documents from time to time, it being understood that such accounts shall not in any way expand or otherwise affect the Collateral Agent’s duties under the Security Documents. The Trustee and the Collateral Agent are hereby deemed to be authorized by the Holders to enter into the Security Documents and the Intercreditor Agreement upon direction from PES, but without consent from the Holders. In entering into the Intercreditor Agreement, the Trustee and the Collateral Agent shall be entitled to receive and conclusively rely upon an instruction from PES, together with an Opinion of Counsel and an Officers’ Certificate compliant with Sections 13.04 and 13.05.

Section 10.02 Recording and Opinions.

(a) PES will furnish to the Collateral Agent and the Trustee on or within one month of March 1 in each year beginning with March 1, 2012, an Opinion of Counsel either:

(1) (A) stating that, in the opinion of such counsel, action has been taken with respect to the recording, registering, filing, re-recording, re-registering and re-filing of all supplemental indentures, mortgages, financing statements, mortgage reinscriptions, continuation statements or other instruments of further assurance as is necessary to maintain the Lien of the Security Documents and reciting with respect to the security interests in the Collateral the details of such action or referring to prior Opinions of Counsel in which such details are given, and (B) stating that, in the opinion of such counsel, based on relevant laws as in effect on the date of such Opinion of Counsel, all mortgages, mortgage reinscriptions, financing statements and continuation statements have been filed that are necessary as of such date and during the succeeding 12 months to

103

fully preserve and protect, to the extent such protection and preservation are possible by filing, the rights of the Holders of Notes and the Collateral Agent and the Trustee hereunder and under the Security Documents with respect to the security interests in the Collateral;

(2) stating that, in the opinion of such counsel, no such action is necessary to maintain such Lien and assignment.

(b) PES will otherwise comply with the provisions of TIA §314(b).

Section 10.03 Release of Collateral.

(a) Subject to subsections (b), (c) and (d) of this Section 10.03, Collateral may be released from the Lien and security interest created by the Security Documents in accordance with the provisions of the Security Documents and under the following circumstances:

(1) if any Subsidiary that is a Guarantor is released from its Guarantee pursuant to the terms of this Indenture, that Subsidiary’s assets will also be released from the Liens securing the Notes;

(2) pursuant to Section 9.02 hereof, with consent of Holders of a majority of the outstanding Notes;

(3) if required in accordance with the terms of the Intercreditor Agreement;

(4) if such Collateral becomes Excluded Assets;

(5) if the First Priority Lien on such Collateral is released, other than a release following a discharge of First Lien Obligations;

(6) if PES exercises its Legal Defeasance option or Covenant Defeasance option pursuant to Sections 8.01, 8.02 and 8.03 hereof;

(7) upon satisfaction and discharge of this Indenture or payment in full of the principal of, and premium and accrued and unpaid interest on, the Notes and all other Obligations that are then due and payable pursuant to Section 12.01 hereof.

(b) In addition, upon the request of PES pursuant to an Officers’ Certificate certifying that all conditions precedent hereunder have been met and stating whether or not such release is in connection with a sale or disposition of assets and (at the sole cost and expense of PES) the Collateral Agent will release Collateral that is sold, conveyed or disposed of in compliance with the provisions of this Indenture; provided that if such sale, conveyance or disposition constitutes an Asset Sale, such Asset Sale complies with the requirements of Section 4.10 hereof.

(c) PES shall determine the applicability of TIA 314(d) to any such release, and if PES determines that TIA 314(d) is not applicable it shall include a statement to this effect in the Officers’ Certificate to be provided under clause (d). Any certificate or opinion required by TIA § 314(d) may be made by an Officer of PES except in cases where TIA § 314(d) requires that

104

such certificate or opinion be made by an independent Person, which Person will be an independent engineer, appraiser or other expert selected or approved by PES in the exercise of reasonable care. If PES determines that TIA 314(d) is not applicable to the release of Collateral, then PES need not deliver the documents that would otherwise be required under TIA 314(d); provided however, that in no event is this intended to derogate the right of the Trustee and Collateral Agent to request and obtain an Opinion of Counsel and Officers’ Certificate stating that all conditions precedent in the Indenture Documents to such release have been complied with whenever the Trustee and/or Collateral Agent is asked to execute or acknowledge a release of Collateral.

(d) Notwithstanding anything to the contrary contained herein, at any time the Trustee or Collateral Agent is requested to acknowledge or execute a release of Collateral, the Trustee and/or the Collateral Agent shall be entitled to receive an Opinion of Counsel and Officers’ Certificate that all conditions precedent in the Indenture Documents to such release have been complied with. The Trustee may, to the extent permitted by Sections 7.01 and 7.02 hereof, accept as conclusive evidence of compliance with the foregoing provisions the appropriate statements contained in such documents and such Opinion of Counsel. Upon receipt of such documents the Collateral Agent shall execute, deliver or acknowledge any instruments of termination, satisfaction or release reasonably requested of it to evidence the release of any Collateral permitted to be released pursuant to this Indenture or the Security Documents.

Section 10.04 [Reserved]

Section 10.05 Authorization of Actions to Be Taken by the Trustee Under the Security Documents.

Subject to the provisions of Sections 7.01 and 7.02 hereof, the Trustee may, in its sole discretion and without the consent of the Holders of Notes, direct, on behalf of the Holders of Notes, the Collateral Agent to, take all actions it deems necessary or appropriate in order to:

(1) enforce any of the terms of the Security Documents; and

(2) collect and receive any and all amounts payable in respect of the Obligations of PES hereunder.

The Trustee will have power to institute and maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any acts that may be unlawful or in violation of the Security Documents or this Indenture, and such suits and proceedings as the Trustee may deem expedient to preserve or protect its interests and the interests of the Holders of Notes in the Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be prejudicial to the interests of the Holders of Notes or of the Trustee).

105

Section 10.06 Authorization of Receipt of Funds by the Trustee Under the Security Documents.

The Trustee is authorized to receive any funds for the benefit of the Holders of Notes distributed under the Security Documents, and to make further distributions of such funds to the Holders of Notes according to the provisions of this Indenture.

Section 10.07 Termination of Security Interest.

Upon the payment in full of all Obligations of PES under this Indenture and the Notes, or upon Legal Defeasance, the Trustee will, at the request of PES, deliver a certificate to the Collateral Agent stating that such Obligations have been paid in full, and instruct the Collateral Agent to release the Liens pursuant to this Indenture and the Security Documents.

Section 10.08 Trustee’s Duties with Respect to Collateral

(a) Beyond the exercise of reasonable care in the custody thereof, the Trustee shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Trustee shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee in good faith.

(b) The Trustee shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Trustee, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of PES to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Trustee shall have no duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture or the Security Documents by PES, the Guarantors, the Second Lien Creditors or the Collateral Agent.

ARTICLE 11

GUARANTEES

Section 11.01 Guarantee.

(a) The Guarantors, jointly and severally, on a senior secured basis, irrevocably, absolutely and unconditionally guarantee to each Holder of Notes and the Trustee the prompt and complete payment and performance when due, irrespective of the validity and enforceability of

106

this Indenture, the Notes or the obligations of PES thereunder, no matter how the same shall become due, of all Guaranteed Obligations.

(b) If PES shall for any reason fail to pay any Guaranteed Obligation, as and when such Guaranteed Obligation shall become due and payable, whether at its stated maturity, as a result of the exercise of any power to accelerate, or otherwise, the Guarantors will, upon demand by the Trustee, pay such Guaranteed Obligation in full to the Trustee for the benefit of the Holders of Notes and the Trustee to which such Guaranteed Obligation is owed. If PES shall for any reason fail to perform promptly any Guaranteed Obligation that is not for the payment of money, the Guarantors will, upon demand by the Trustee, cause such Guaranteed Obligation to be performed or, if specified by the Trustee, provide sufficient funds, in such amount and manner as the Trustee shall in good faith determine, for the prompt, full and faithful performance of such Guaranteed Obligation by the Trustee or such other Person as the Trustee shall designate. Without limiting the generality of the foregoing, the Guarantors will pay all amounts that constitute part of the Guaranteed Obligations that would be owing but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding.

Section 11.02 Execution and Delivery of Guarantee.

(a) To evidence its Note Guarantee set forth in Section 11.01 hereof, 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, by manual or facsimile signature, 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.

(b) Each Guarantor hereby agrees that its Note Guarantee set forth in Section 11.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

(c) 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.

(d) 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.

(e) In the event that PES or any of its Restricted Subsidiaries creates or acquires any Domestic Subsidiary after the date of this Indenture, if required by Section 4.16 hereof, PES will cause such Domestic Subsidiary to comply to the extent applicable with the provisions of Section 4.16 hereof, this Article 11.

107

Section 11.03 [Reserved.]

Section 11.04 Limitation of Liability of Certain Guarantors.

(a) Notwithstanding any other provision of this Article 11, each Guarantor confirms that it is the intention of each such Guarantor that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law 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 11, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent transfer or conveyance.

(b) Notwithstanding any other provision of this Article 11, with respect to any Guarantor guaranteed hereby and the liability of such Guarantor for all obligations under this Article 11 and any Indenture Document to which it is a party, liability shall be limited to the maximum liability that can be incurred by such Guarantor without rendering this Guarantee subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provisions of any applicable state or federal law.

Section 11.05 Unconditional Guaranty.

(a) Each Guarantor will pay the Guaranteed Obligations strictly in accordance with the terms of the Indenture Documents to the extent permitted by law regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any such term or any right of any Second Lien Creditor with respect thereto.

(b) This is a guarantee of payment and not of collection. The obligations of each Guarantor under or in respect of this Article 11 and each Indenture Document to which such Guarantor is a party are independent of the Guaranteed Obligations or any other obligation of PES or any other Guarantor under or in respect of the Indenture Documents, and a separate action or actions may be brought and prosecuted against such Guarantor to enforce this Guarantee, irrespective of whether any action is brought against PES or any other Guarantor or whether PES or any other Guarantor is joined in any such action or actions.

(c) The obligations of each Guarantor under this Article 11 and each Indenture Document to which such Guarantor is a party shall not, to the maximum extent permitted by law, be affected by:

(1) any voluntary or involuntary liquidation, dissolution, sale of all or substantially all assets, marshalling of assets or liabilities, receivership, conservatorship, assignment for the benefit of creditors, insolvency, bankruptcy, reorganization, arrangement, or composition of PES or any other Guarantor;

108

(2) any other proceeding involving PES or any other Guarantor or any asset of PES or any other Guarantor under any law for the protection of debtors; or

(3) any discharge, impairment, modification, release, or limitation of the liability of, or stay of actions or lien enforcement proceeding against, PES or any other Guarantor, any property of PES or any other Guarantor, or the estate in bankruptcy of PES or any other Guarantor in the course of or resulting from any such proceeding.

Section 11.06 No Release Based on Actions of the Second Lien Creditors

Except as expressly provided in this Indenture, no action that the Collateral Agent or any other Second Lien Creditor may take or omit to take in connection with any Indenture Document, any Guaranteed Obligation (or any other indebtedness owing by PES to any Second Lien Creditor), or any collateral security, and no course of dealing between any Second Lien Creditor and PES, any Guarantor or any other Person, shall release or diminish any Guarantor’s Guaranteed Obligations, liabilities, agreements or duties hereunder, affect this Guarantee or any Indenture Document to which Guarantor is a party, or afford any Guarantor any recourse against any Second Lien Creditor, regardless of whether any such action or inaction may increase any risk to or liability of any Second Lien Creditor, PES or any Guarantor or increase any risk to or diminish any safeguard of any collateral security.

Section 11.07 Waivers.

The liability of each Guarantor under this Article 11 and each Indenture Document to which such Guarantor is a party shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor irrevocably waives, for purposes of this Article 11 and each Indenture Document to which such Guarantor is a party, any defense that it may now have or hereafter acquire relating to any or all of the following (and each Guarantor acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements contemplated by the Indenture Documents and that the waivers set forth below and otherwise in this Article 11 are knowingly made in contemplation of such benefits), in each case to the maximum extent permitted by law:

(1) Any lack of validity or enforceability of any Indenture Document, any agreement or instrument relating thereto, any defense arising by reason of any disability or other defense of any other Person or the cessation from any cause whatsoever of the liability of any other Person.

(2) Any change in the time, manner or place of payment of, or in any other term of, any Guaranteed Obligation or any other Obligation of PES or any Guarantor in respect of the Indenture Documents, or any other amendment or waiver of or any consent to departure from any Indenture Document, including any increase in the Guaranteed Obligations resulting from the extension of additional credit to PES or any Guarantor or any of its Subsidiaries or otherwise.

(3) Any taking, exchange, release or non-perfection of any collateral security, or any taking, release or amendment or waiver of, or consent to departure from any other guarantee of any Guaranteed Obligation.

109

(4) Any manner of application of collateral security, or proceeds thereof, to any Guaranteed Obligation, or any manner of sale or other disposition of any collateral security securing any Guaranteed Obligation or any other obligation of PES or any Guarantor under the Indenture Documents or any other asset of PES or any Guarantor or any of its Subsidiaries, and any other obligation to marshal assets.

(5) Any right to require any Second Lien Creditor to proceed against any other Person, to exhaust any collateral security for the Guaranteed Obligations, to have any other Person joined with any Guarantor in any suit arising out of the Guaranteed Obligations or this Article 11 or to pursue any other remedy in any Second Lien Creditor’s power.

(6) Any change or restructuring of the corporate structure or termination of the existence of PES or any Guarantor or any of its Subsidiaries.

(7) Any failure of any Second Lien Creditor to disclose to PES or any Guarantor any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of PES or any Guarantor now or hereafter known to such Second Lien Creditor (each Guarantor waiving any duty on the part of the Second Lien Creditors to disclose such information).

(8) Any failure of any other Person to execute or deliver any notation of guarantee, any supplement hereto or any other guarantee or agreement.

(9) Any release or reduction of the liability of any Guarantor or other guarantor or surety with respect to the Guaranteed Obligations or any other compromise or settlement of the Guaranteed Obligations.

(10) Promptness, diligence, notice of acceptance, presentment, demand for performance, notice of non-performance, default, acceleration, protest or dishonor and, to the extent permitted by law, any other notice with respect to any Guaranteed Obligation and this Article 11, including notice of acceptance of this Article 11.

(11) Any requirement that any Second Lien Creditor create or perfect any Lien or protect or insure any property subject thereto.

(12) Any right to revoke the provisions of this Article 11.

(13) Any election of remedies by any Second Lien Creditor that in any manner impairs, reduces, releases or otherwise adversely affects any collateral security or any subrogation, reimbursement, exoneration, contribution or indemnification right of any Guarantor or other right of any Guarantor to proceed against PES or any Guarantor, any other guarantor, any other Person or any collateral security.

(14) Any right of set-off or counterclaim against or in respect of the Guaranteed Obligations of any Guarantor hereunder.

(15) Any neglect, failure or refusal to take any action:

110

(a) for the collection or enforcement of any Guaranteed Obligation,

(b) to realize on any collateral security,

(d) to file or enforce a claim in any proceeding described in Section 11.05(c),

(e) in connection with the administration of any Indenture Document or

(17) Any duty of any Second Lien Creditor to disclose to any Guarantor any matter, fact or thing relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of PES or any Guarantor or any of its Subsidiaries now or hereafter known by such Second Lien Creditor.

(18) Any defense to the recovery by any Second Lien Creditor against any Guarantor of any deficiency after a non-judicial sale and any defense or benefit that may be afforded by applicable law (and in that connection each Guarantor acknowledges that the Collateral Agent may, to the extent permitted by applicable law, without notice to or demand upon such Guarantor and without affecting the liability of such Guarantor under this Article 11, foreclose under any mortgage by non-judicial sale).

(19) Any statute of limitations applicable to the Guaranteed Obligations.

(20) To the extent permitted by law, any other circumstance or any existence of or reliance on any representation by any Second Lien Creditor, except for indefeasible payment in full in cash and performance in full of each Guaranteed Obligation, that might otherwise constitute a defense available to, or a discharge of, any Guarantor or PES or any other guarantor or surety.

Section 11.08 Continuing Guaranty; Reinstatement.

(a) The Note Guarantee set forth in this Article 11 is a continuing guaranty and shall remain in full force and effect until the indefeasible payment in full in cash of the Guaranteed Obligations and all other amounts payable hereunder, unless released in accordance with this Article 11.

(b) This Article 11 and each Indenture Document to which any Guarantor is a party shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any Guaranteed Obligation is rescinded or must otherwise be returned by any Second Lien

111

Creditor as a result of the insolvency, bankruptcy or reorganization of PES or any Guarantor or otherwise, all as though such payment had not been made, and each Guarantor jointly and severally will pay such amount to the applicable Second Lien Creditor on demand. Any transfer by subrogation that is made as contemplated in Section 11.09(b) prior to any such payment shall (regardless of the terms of such transfer) be automatically voided upon the making of any such payment or payments, and all rights so transferred shall thereupon automatically revert to and be vested in the Second Lien Creditors.

Section 11.09 Subordination; Subrogation; Contribution

(a) Subordination. Each Guarantor subordinates all debts, liabilities and other Obligations owed to such Guarantor by PES or any other Guarantor (the “Subordinated Obligations”) to the Guaranteed Obligations as follows:

(1) Except during the continuance of a Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to PES or any other Guarantor), any Guarantor may receive regularly scheduled payments from PES or any other Guarantor on account of the Subordinated Obligations. After the occurrence and during the continuance of any Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to PES or any Guarantor), unless the Collateral Agent, subject to the provisions of the Intercreditor Agreement, otherwise agrees, no Guarantor shall demand, accept or take any action to collect any payment on account of any Subordinated Obligation.

(2) In any proceeding under any Bankruptcy Law relating to PES or any Guarantor, the Second Lien Creditors shall be entitled to receive payment in full in cash of all Guaranteed Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Bankruptcy Law, whether or not constituting an allowed claim in such proceeding (“Post-Petition Interest”)) before any Guarantor receives payment of any Subordinated Obligation.

(3) After the occurrence and during the continuance of any Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to PES or any Guarantor), each Guarantor shall, if the Collateral Agent, subject to the provisions of the Intercreditor Agreement, so requests, collect, enforce and receive payments on account of the Subordinated Obligations as Collateral Agent for the Second Lien Creditors and deliver such payments to the Collateral Agent on account of the Guaranteed Obligations (including all Post-Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of such Guarantor under the other provisions of this Article 11.

(b) Limited Right of Subrogation.

(1) Until all Guaranteed Obligations have been indefeasibly paid in full in cash and otherwise performed in full, and all obligations under each Indenture Document to which any Guarantor is a party have been paid and performed in full, no Guarantor shall have any right of subrogation, reimbursement, indemnity, exoneration, contribution

112

or any other claim against PES or any other Guarantor or any collateral security in connection with the Guarantee provided in this Article 11. Until such time, each Guarantor waives any right to enforce any remedy that such Guarantor may have against PES and any right to participate in any collateral security.

(2) If any amount shall be paid to any Guarantor on account of any subrogation or other right, any such other remedy, or any collateral security at any time when all of the Guaranteed Obligations and all other expenses guaranteed pursuant hereto shall not have been paid in full, such amount shall be held in trust for the benefit of the Second Lien Creditors, shall be segregated from the other funds of such Guarantor and, subject to the provisions of the Intercreditor Agreement, shall forthwith be paid over to the Trustee to be held by the Trustee for the benefit of the Second Lien Creditors as collateral security for, or then or at any time thereafter applied in whole or in part by the Trustee against, any Guaranteed Obligation, whether matured or unmatured, in such order as the Trustee shall elect.

(3) If any Guarantor shall have paid off any Guaranteed Obligation and if all of the Guaranteed Obligations shall have been indefeasibly paid in full in cash, the Trustee will, at the Guarantors’ expense and reasonable request, execute and deliver to such applicable Guarantor (without recourse, representation or warranty) appropriate documents necessary to evidence the transfer, without representation or warranty, by subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such payment by the Guarantors; provided that:

(A) such transfer shall be subject to Section 11.08(b), and

(B) without the consent of the Collateral Agent (which the Collateral Agent may withhold in its reasonable discretion) no Guarantor shall have the right to be subrogated to any claim or right against PES or any other Guarantor that has become owned by any Second Lien Creditor, whose ownership has otherwise changed in the course of enforcement of the Indenture Documents, or that the Collateral Agent otherwise has released or wishes to release from its Guaranteed Obligations.

(c) Right of Contribution. After all Guaranteed Obligations have been indefeasibly paid in full in cash and otherwise performed in full, and all obligations under each Indenture Document to which any Guarantor is a party have been paid and performed in full, the Guarantors that have made payments in respect of the Guaranteed Obligations shall be entitled to contribution from the other Guarantors, to the end that all such payments upon the Guaranteed Obligations shall be shared among all such Guarantors in proportion to their respective Net Worths; provided that the contribution obligations of each such Guarantor shall be limited to the maximum amount that it can pay at such time without rendering its contribution obligations voidable under applicable law relating to fraudulent conveyances or fraudulent transfers. “Net Worth” means, at any time and for any Guarantor:

(1) the fair value of such Guarantor’s assets (other than such right of contribution), minus

113

(2) the fair value of such Guarantor’s liabilities (other than its liabilities under its guaranty of the Guaranteed Obligations).

Section 11.10 Guarantors May Consolidate, etc., on Certain Terms.

(a) Except as otherwise provided in Section 11.11 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than PES or another Guarantor, unless:

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

(2) either:

(A) subject to Section 11.11 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of that Guarantor under this Indenture, its Note Guarantee pursuant to a supplemental Indenture and appropriate Security Documents satisfactory to the Trustee; or

(B) such sale or other disposition complies with Section 4.10 hereof.

(b) 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 reasonably 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. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees issuable hereunder which theretofore shall not have been signed by the Guarantor and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof.

(c) Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (a)(2)(A) and (a)(2)(B) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into PES 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 PES or another Guarantor.

Section 11.11 Releases.

The Guarantee of a Guarantor will be released:

(1) in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person

114

that is not (either before or after giving effect to such transaction, PES or a Restricted Subsidiary of PES, if the sale or other disposition is not prohibited by Section 4.10 hereof;

(2) in connection with any sale, transfer or other disposition of all of the Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) PES or a Restricted Subsidiary of PES, if the sale, transfer or other disposition is not prohibited by Section 4.10 hereof;

(3) if PES designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with Section 4.17 hereof;

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

(5) as provided in the Intercreditor Agreement.

Any Guarantor not released from its obligations under its Guarantee as provided in this Section 11.11 will remain liable for the full amount of principal of and interest and premium and Additional Interest, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 11.

Upon delivery by PES to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by PES in accordance with the provisions of this Indenture, including without limitation Section 4.10 hereof, the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Guarantee.

For any Guarantor released from its Guarantee under this Section 11.11, the liens on the Collateral of such Guarantor will also be released under the Security Documents, in accordance with Section 10.03.

ARTICLE 12

SATISFACTION AND DISCHARGE

Section 12.01 Satisfaction and Discharge.

This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when:

(1) either:

(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 theretofore been deposited in trust and thereafter repaid to PES, have been delivered to the Trustee for cancellation; or

115

(b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and PES 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, interest, premium and Additional Interest, if any, and accrued interest to the date of maturity or redemption;

(2) no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which PES or any Guarantor is a party or by which PES or any Guarantor is bound;

(3) PES or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and

(4) PES has delivered irrevocable instructions to the Trustee under this Indenture 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, PES must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to Section 12.01(1)(b), the provisions of Sections 12.02 and 8.06 hereof will survive. In addition, nothing in this Section 12.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 12.02 Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 12.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including PES acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium and Additional Interest, if any) and interest 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 12.01 hereof 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, PES’s 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

116

12.01 hereof; provided that if PES has made any payment of principal of, premium or Additional Interest, if any, or interest on, any Notes because of the reinstatement of its obligations, PES 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.

[Back of Note]

14.250% Senior Secured Notes due 2015

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) INTEREST. Platinum Energy Solutions, Inc., a Nevada corporation (“PES”), promises to pay interest on the principal amount of this Note at 14.250% per annum from September 1, 2011 until maturity; provided, however, that the first interest payment on September 1, 2011 may be capitalized and added to the principal amount of the Note at PES’s option. PES shall pay the Additional Interest, if any, payable pursuant to Section 4 of the Registration Rights Agreement referred to below. PES will pay interest and Additional Interest, if any, semi-annually in arrears on March 1 and September 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”); Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be September 1, 2011. PES will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest (without regard to any applicable grace period) at the same rate to the extent lawful.

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

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

(4) INDENTURE. PES issued the Notes under an Indenture dated as of March 3, 2011 (the “Indenture”) among PES, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA. The Notes are subject to all such terms, and Holders are referred to the Indenture and to the TIA for a statement of such terms. To the extent any provision

A-1-4

of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are secured obligations of PES as provided in the Indenture and the Security Documents. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.

(5) Optional Redemption.

(a) Except as set forth in subparagraphs (b) and (c) of this Paragraph 5, the Notes will not be redeemable at PES’s option prior to March 1, 2013. On or after March 1, 2013, PES may redeem the Notes, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and Additional Interest, if any, on the Notes redeemed, to, but not including, the applicable redemption date, if redeemed during the period set forth below, subject to the rights of Holders on the relevant record date to receive interest on the relevant Interest Payment Date:


For the period below	Percentage
On or after March 1, 2013 to February 28, 2014		107.125	%
On or after March 1, 2014 and thereafter		100.000	%

Unless PES 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.

(b) At any time on or prior to March 1, 2013, PES may on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes issued under this Indenture at a redemption price of 114.250% of the aggregate principal amount, plus accrued and unpaid interest and Additional Interest, if any, on the Notes to be redeemed to but not including the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the redemption date), with the net cash proceeds of one or more Equity Offerings by PES, provided that:

(i)

at least 65% of the aggregate principal amount of Notes originally issued under this Indenture remains outstanding immediately after the occurrence of such redemption (excluding Notes held by PES and its Subsidiaries); and

(ii)

the redemption occurs within 90 days of the date of the closing of such Equity Offering.

A-1-5

plus the Applicable Premium, and accrued and unpaid interest and Additional Interest, if any, to, but not including, the redemption date, subject to the rights of holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date.

Unless PES 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.

(6) MANDATORY REDEMPTION.

PES is not required to make mandatory redemption or sinking fund payments with respect to the Notes. PES may at any time and from time to time purchase the Notes in the open market or otherwise if such purchase complies with the then applicable agreements of PES, including this Indenture.

(7) REPURCHASE AT THE OPTION OF HOLDER.

(a) Upon the occurrence of a Change of Control, PES will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Additional Interest, if any, on the Notes repurchased to the date of settlement (the “Change of Control Payment Date”), subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date (the “Change of Control Payment”). Within 15 days following any Change of Control, PES will mail a notice to each Holder and the Trustee describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes as of the Change of Control Payment 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 mailed, pursuant to the procedures required by the Indenture and described in such notice.

(b) If PES or a Restricted Subsidiary of PES consummates any Asset Sales, on the 361st day after the Asset Sale (or, at PES’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $5.0 million, PES will make an Asset Sale Offer to all Holders of Notes, and, at PES’s option, all holders of Other Pari Passu Obligations, to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest and Additional Interest, if any, to the date of settlement, subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the date of settlement, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, PES may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and, if applicable, Other Pari Passu Obligations tendered into such Asset Sale Offer exceeds the amount of Excess

A-1-6

Proceeds, the Trustee will select the Notes and such Other Pari Passu Obligations to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(c) Within 100 days after each Determination Date for which the Excess Cash Flow of PES and its Restricted Subsidiaries for the applicable Excess Cash Flow Offer Determination Period exceeds $2.5 million (the “Excess Cash Flow Offer Threshold”), and to the extent permitted by its Credit Facilities, PES will make an offer in cash in an amount equal to the Excess Cash Flow Offer Amount to purchase Notes (an “Excess Cash Flow Offer”) at an offer price equal to 100% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase (the “Excess Cash Flow Offer Payment”). If the aggregate principal amount of Notes tendered in such Excess Cash Flow Offer exceeds the Excess Cash Flow Offer Amount, the Trustee will select the Notes to be purchased on a pro rata basis, by lot or by such other method as the Trustee deems fair and appropriate. To the extent that the aggregate amount of Notes tendered pursuant to an Excess Cash Flow Offer is less than the Excess Cash Flow Offer Amount, PES may use any remaining Excess Cash Flow Amount for any purpose not otherwise prohibited by the Indenture. Upon completion of any such Excess Cash Flow Offer, the Excess Cash Flow Amount shall be reset at zero; provided that PES will not be deemed to be in default under this covenant for any failure to make an Excess Cash Flow Offer or an Excess Cash Flow Offer Payment by virtue of any adjustment in the amount calculated for any Excess Cash Flow Offer Determination Period due to normal year-end accounting adjustments or other changes concurred in by its public accountants; provided further that any such adjustment in the calculation of the Excess Cash Flow for a prior Excess Cash Flow Offer Determination Period, whether positive or negative, shall be carried forward to the next subsequent Excess Cash Flow Offer Determination Period. Within 100 days following each such Determination Date, PES will mail a notice to each Holder and the Trustee offering to repurchase Notes as of the date specified in the notice (the “Excess Cash Flow Offer Purchase Date”), which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by the Indenture and described in such notice.

Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed.

(9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the

A-1-7

Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and PES may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. PES need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, PES need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold notice of any continuing Default or Event of Default from Holders of the Notes if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal of, or interest, premium or Additional Interest, if any, on, the Notes. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration and its consequences, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium or Additional Interest, if any, that has become due solely because of the acceleration) have been cured or waived.

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

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