Section 2.01 Form and Dating.

(a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibits A1 and A2 hereto. 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 issued only in fully registered form without coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Company, 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.

(b) Global Notes. Notes issued in global form will be substantially in the form of Exhibits A1 or A2 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 A1 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, 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 the Company and authenticated by the Trustee as hereinafter provided. The Restricted Period will be terminated upon the receipt by the Trustee of:

(1) a written certificate from the Depositary, together with copies of certificates from Euroclear and Clearstream certifying that they have received certification of non-United States beneficial ownership of 100% of the aggregate principal amount of the Regulation S Temporary Global Note (except to the extent of any beneficial owners thereof who acquired an interest therein during the Restricted Period pursuant to another exemption from registration under the Securities Act and who will take delivery of a beneficial ownership interest in a 144A Global Note or an IAI Global Note bearing a Private Placement Legend, all as contemplated by Section 2.06(b) hereof); and

(2) an Officers’ Certificate from the Company.

Within a reasonable time period after 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.

(3) 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 must sign the Notes for the Company by manual or facsimile signature.

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

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

The Trustee will, upon receipt of a written order of the Company signed by two Officers (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

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

Additional Notes may be created and issued from time to time by the Company without notice to or consent of the Holders and shall be consolidated with and form a single class with the Initial Notes and shall have the same terms as the Initial Notes; provided that the Company's ability to issue Additional Notes shall be subject to the Company's compliance with this Section 2.02 and Section 4.09 and the other provisions hereof.

Section 2.03 Registrar and Paying Agent.

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

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

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

Section 2.04 Paying Agent to Hold Money in Trust.

The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium on, if any, interest or Additional Interest, if any, on, the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, 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, the Company will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company 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.

Upon receipt of a request for such an exchange or transfer, the Trustee will cancel the applicable Unrestricted Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Unrestricted Global Notes.

If any such exchange or transfer from a Definitive Note to a beneficial interest is effected pursuant to subparagraphs (2)(B), (2)(D) or (3) above at a time when an Unrestricted Global Note has not yet been issued, the Company will issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee will authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the principal amount of Definitive Notes so transferred.

(h) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. 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, the Company 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.

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

(4) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Company, 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 the Company will be required:

(A) to issue, to register the transfer of or to exchange any Notes in respect of which a notice of redemption has been given or for a period of 15 days before a selection of the Notes to be redeemed under Section 3.02 hereof and ending at the close of business on the day of such 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.

Section 2.07 Replacement Notes.

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

Every replacement Note is an additional obligation of the Company 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 the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

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

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

If the Paying Agent (other than the Company, 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 the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company 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, the Company may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

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

Section 2.11 Cancellation.

The Company 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 Company will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, if given prior notice in accordance with Section 12.02, the Trustee in the name and at the expense of the Company) 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 Trustee Disclaimer.

The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in the Depositary or any other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption or repurchase) or the payment of any amount, under or with respect to the Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to applicable rules and procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

Section 2.14 CUSIP and ISIN Numbers.

The Company in issuing the Notes may use CUSIP numbers and/or ISIN numbers (if then generally in use) and, if so, the Trustee shall use CUSIP numbers and/or ISIN numbers in notices (including 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. The Company will as promptly as possible notify the Trustee, in writing, of any change in the CUSIP number and ISIN number.

ARTICLE 3

REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at least 45 days before a redemption date (unless a shorter notice shall be satisfactory to the Trustee), an Officers’ Certificate setting forth:

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

(2) the redemption date;

(3) the principal amount of Notes to be redeemed; and

(4) the redemption price.

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

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

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

The Trustee will promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

Section 3.03 Notice of Redemption.

Subject to the provisions of Section 3.09 hereof, notices of redemption with respect to the Notes shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address, 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 11 hereof.

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

(1) the redemption date;

(2) the redemption price;

(3) if any Note is being redeemed in part only, 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 in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note;

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

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

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

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

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

At the Company’s request, the Trustee will give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 45 days 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.

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 date fixed for redemption at the redemption price. Notices of redemption may not be conditional.

Section 3.05 Deposit of Redemption or Purchase Price.

One Business Day prior to the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of, 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 the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, accrued interest and Additional Interest, if any, on all Notes to be redeemed or purchased.

If the Company 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 the Company 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, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

Section 3.07 Optional Redemption.

(a) At any time and from time to time before May 1, 2013, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the outstanding Notes (which amount includes any Additional Notes), at a redemption price of 110½% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest thereon to the redemption date, with the net cash proceeds of any one or more Equity Offerings; provided that at least 65% of the aggregate principal amount of Notes issued under this Indenture (which amount includes Additional Notes, but excludes Notes held by the Company and its Subsidiaries) remains outstanding immediately after each such redemption; and provided, further, that each such redemption shall occur within 90 days of the date of the closing of such Equity Offering.

(b) At any time and from time to time prior to May 1, 2014 the Company may, at its option, redeem all or a portion of the Notes at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium with respect to the Notes plus accrued and unpaid interest and Additional Interest thereon to the redemption date.

(c) Except pursuant to the preceding paragraphs, the Notes will not be redeemable at the Company’s option prior to May 1, 2014.

(d) On or after May 1, 2014, the Notes will be subject to redemption at any time and from time to time at the option of the Company, in whole or in part, at the redemption prices (expressed as percentages of the principal amount redeemed) set forth below plus accrued and unpaid interest and Additional Interest thereon to the applicable redemption date, if redeemed during the twelve-month period beginning on May 1 of the years indicated below.

Year	Percentage

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

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

Section 3.08 Mandatory Redemption.

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

Section 3.09 Offer to Purchase by Application of Excess Asset Sale Proceeds.

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

The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Asset Sale Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest and 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 additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, 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) 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;

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

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

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

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

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

(7) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

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

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

On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on or as soon as practicable after the Asset Sale Offer is completed.

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

COVENANTS

Section 4.01 Payment of Notes.

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

The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that is 1% higher than 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, if any (without regard to any applicable grace period), at the same rate to the extent lawful.

Section 4.02 Maintenance of Office or Agency.

The Company will maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company 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 the Company 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.

The Company 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. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

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

Section 4.03 Reports.

Whether or not required by the SEC’s rules and regulations, so long as any Notes are outstanding, the Company will furnish to the Trustee and each Holder of Notes, 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 the Company 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 the Company were required to file such reports.

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 the Company’s consolidated financial statements by the Company’s certified independent accountants. In addition, the Company 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 make such information available to securities analysts and prospective investors upon request.

If at any time the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company will nevertheless continue filing the reports specified in the preceding paragraph with the SEC within the time periods specified above unless the SEC will not accept such a filing. The Company agrees that it will not take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the preceding, the SEC will not accept the Company’s filings for any reason, the Company will post the reports referred to in the preceding paragraph on its website within the time periods that would apply if the Company were required to file those reports with the SEC.

In addition, the Company and the Guarantors agree that, for so long as any Notes remain outstanding, at any time the Company is not required to file the reports required by the preceding paragraphs with the SEC, they will furnish to the Holders 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.

The Company will be deemed to have furnished such reports to the Trustee and the Holders of Notes if it has filed such reports with the SEC using the ▇▇▇▇▇ filing system and such reports are publicly available. If the Company fails to so file such reports, it shall promptly notify the Trustee and until the Trustee receives such notification, it is entitled to presume such reports were so filed.

Delivery of the above reports to the Trustee is for informational purposes only and the Trustee’s access to, or receipt of, such reports will not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants in the Indenture (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 4.04 Compliance Certificate.

(a) The Company and each Guarantor (to the extent that such Guarantor is so required under the TIA) shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company 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 the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture 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 the Company 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, premium on, if any, interest or Additional Interest, if any, on, the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto.

(b) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end financial statements delivered pursuant to Section 4.03 above shall be accompanied by a written statement of the Company’s independent public accountants (who shall be a firm of established national reputation) that in making the examination necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that the Company has violated any provisions of Article 4 or Article 5 hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation.

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

Section 4.05 Taxes.

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

Section 4.06 Stay, Extension and Usury Laws.

The Company 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 the Company 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 4.07 Restricted Payments.

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

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

The preceding provisions of this Section 4.07 shall not prohibit:

(1) the payment of any dividend or the consummation of an irrevocable redemption of Subordinated Obligations within 60 days after the date of the declaration of such dividend or the delivery of the irrevocable notice of redemption, as the case may be, if at the date of the declaration or the date on which such irrevocable notice is delivered, such dividend or redemption would have complied with the provisions of this Indenture;

(2) the making of any Restricted Payments described in clause (2) or (3) of the preceding paragraph out of the net cash proceeds of the substantially concurrent sale or issuance (a sale or issuance will be deemed substantially concurrent if such Restricted Payment occurs not more than 60 days after such sale or issuance) (other than to a Restricted Subsidiary of the Company) of Equity Interests of the Company (other than any Disqualified Stock); provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment shall be excluded from clause (4)(c)(ii) of the preceding paragraph;

Section 4.08 Dividend and Other Payment Restrictions Affecting Subsidiaries.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary of the Company to:

(1) (x) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries on its Capital Stock or (y) pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries; provided, that the priority of any preferred stock in receiving dividends or liquidating distributions prior to the payment of dividends or liquidating distributions on common stock shall not be deemed to be a restriction on the ability to make distributions on Capital Stock;

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

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

However, the restrictions in the first paragraph of this Section 4.08 will not apply to encumbrances or restrictions existing under or by reason of:

(a) contractual encumbrances or restrictions in effect on the Issue Date, including pursuant to any Existing Indebtedness and the related documentation (including any Credit Facilities that are refinanced with the net proceeds from the issuance of the Notes on the Issue Date) and any Hedging Obligations and the related documentation;

(b) this Indenture, the Notes and the Subsidiary Guarantees;

(c) any future Liens that may be permitted to be granted under, or incurred not in violation of, any other provisions of this Indenture;

(n) restrictions imposed by law.

Section 4.09 Incurrence of Indebtedness and Issuance of Disqualified Stock..

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

The provisions of the first paragraph of this Section 4.09 shall not apply to the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

(1) the incurrence by the Company or any Restricted Subsidiary of Indebtedness pursuant to one or more Credit Facilities; provided, however, that, immediately after giving effect to any such incurrence, the aggregate principal amount (or accreted value, as applicable) of all Indebtedness incurred under this clause (1) and then outstanding does not exceed the greater of (a) $50.0 million or (b) 15.0% of Total Assets;

(2) the incurrence by the Company and the Guarantors of Indebtedness represented by the Notes and the Subsidiary Guarantees to be issued on the Issue Date and the related Exchange Notes and Subsidiary Guarantees to be issued pursuant to the Registration Rights Agreement;

(3) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness, the net proceeds of which are applied to refinance any Indebtedness incurred in respect of any Indebtedness described under clauses (2), (3), (5), (6), (8), (12), (13) or (14) of this paragraph or incurred pursuant to the first paragraph of this Section 4.09;

(4) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that (A) if the Company or any Guarantor is the obligor and a Restricted Subsidiary of the Company that is not a Guarantor is the obligee on such Indebtedness, such Indebtedness will be subordinated to the payment in full of all Obligations with respect to the Notes and the Subsidiary Guarantees, as the case may be, and (B) (1) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (2) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary of the Company shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that is not then permitted by this clause (4);

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations (including any Acquired Debt), in each case, incurred in connection with the purchase of, or for the purpose of financing the purchase of, the cost of construction, improvement or development of, property, plant or equipment used in the Permitted Business of the Company or a Restricted Subsidiary of the Company 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 (5), not to exceed $10.0 million as of any date incurrence;

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

(7) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness consisting of Hedging Obligations entered into in the ordinary course of business and not for speculative purposes;

(8) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from agreements of the Company or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred in connection with the disposition or acquisition of any business or assets of the Company or any of its Restricted Subsidiaries, other than guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business or assets of the Company or any of its Restricted Subsidiaries for the purposes of financing such acquisition; provided, however, that (A) such Indebtedness is not reflected on the balance sheet of the Company or any of its Restricted Subsidiaries (contingent obligations referred to in a footnote to financial statements and not otherwise reflected on the balance sheet will not be deemed to be reflected on such balance sheet for purposes of this clause (A)) and (B) the maximum liability in respect of all such Indebtedness incurred in connection with a disposition shall at no time exceed the gross proceeds including noncash proceeds (the Fair Market Value of such noncash proceeds being measured at the time received and without giving effect to any subsequent changes in value) actually received by the Company and its Restricted Subsidiaries in connection with such disposition;

(9) the guarantee by the Company or any Restricted Subsidiary of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by any other provision of this Section 4.09;

(10) the issuance by a Restricted Subsidiary of the Company of Disqualified Stock or preferred stock to the Company or to any of its Restricted Subsidiaries; provided, however, that any subsequent event or issuance or transfer of any Equity Interests that results in the owner of such Disqualified Stock or preferred stock ceasing to be the Company or any of its Restricted Subsidiaries or any subsequent transfer of such Disqualified Stock or preferred stock to a Person other than the Company or one of its Restricted Subsidiaries, shall be deemed to be an issuance of Disqualified Stock by such Subsidiary that was not permitted by this clause (10);

(11) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness incurred in the ordinary course of business under (A) documentary letters of credit, or surety bonds or insurance contracts, including in connection with insurance premium financing agreements, which are to be repaid in full not more than one year after the date on which such Indebtedness is originally incurred to finance the purchase of goods by the Company or a Restricted Subsidiary of the Company, (B) standby letters of credit, surety bonds or insurance contracts issued for the purpose of supporting (1) workers’ compensation or similar liabilities of the Company or any of its Restricted Subsidiaries or (2) performance, payment, deposit or surety obligations of the Company or any of its Restricted Subsidiaries and (C) bid, advance payment and performance bonds and surety bonds or similar insurance contracts for the Company and its Restricted Subsidiaries, and refinancings thereof;

(12) the incurrence by the Company or any Guarantor of Permitted Acquisition Indebtedness;

(13) the incurrence by any Restricted Subsidiary of Indebtedness in an aggregate principal amount (or accreted value, as applicable), together with all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (13), not to exceed $10.0 million at any one time outstanding; and

(14) the incurrence by the Company or any Guarantor of Indebtedness in an aggregate principal amount (or accreted value, as applicable), together with all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (14), not to exceed $15.0 million at any one time outstanding.

Neither the Company nor any Guarantor will incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Guarantor, as the case may be, unless such Indebtedness is also contractually subordinated in right of payment to the Notes or the Subsidiary Guarantees, as the case may be, on substantially identical terms; provided, however, that no Indebtedness of any Person will be deemed to be contractually subordinated in right of payment to any other Indebtedness of such Person solely by virtue of being unsecured.

For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness (including Acquired Debt) meets the criteria of more than one of the categories of Permitted Debt described above or is entitled to be incurred pursuant to the first paragraph of this Section 4.09, the Company will, in its sole discretion, classify (or later classify or reclassify) in whole or in part such item of Indebtedness in any manner that complies with this Section 4.09 and such item of Indebtedness or a portion thereof may be classified (or later classified or reclassified) in whole or in part as having been incurred under more than one of the applicable clauses or pursuant to the first paragraph hereof. Indebtedness under any Credit Facility, and any guarantees of such Indebtedness outstanding on the Issue Date will be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt in Section 4.09. Accrual of interest, the accretion of accreted value and the payment of interest in the form of additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.09.

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

Section 4.10 Asset Sales.

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

(1) the Company 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 (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received in such Asset Sale is in the form of cash or Cash Equivalents; provided that any of the following items shall be deemed to be cash and Cash Equivalents for the purposes of this clause (2):

(a) the assumption of any liabilities (as shown on the Company’s or the Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary of the Company (other than liabilities that are by their terms subordinated to Notes issued under this Indenture or any Subsidiary Guarantee) by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or the Restricted Subsidiary from further liability;

(b) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or the Restricted Subsidiary into cash or Cash Equivalents within 180 days following their receipt (to the extent of cash or Cash Equivalents received); and

Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or the Restricted Subsidiary, as the case may be, may apply such Net Proceeds, at its option:

(a) to prepay, repay, purchase, repurchase or redeem any secured Indebtedness of the Company or any Restricted Subsidiary of the Company;

(b) to acquire a controlling interest in another business or all or substantially all of the assets or operating line of another business, in each case engaged in a Permitted Business;

(d) to acquire other non-current assets to be used in a Permitted Business.

Pending the final application of any such Net Proceeds, the Company may temporarily reduce Indebtedness under any Credit Facility or otherwise expend or invest such Net Proceeds in any manner that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales described in this paragraph that are not applied or invested as provided in the first sentence of this paragraph of this Section 4.10 shall be deemed to constitute “Excess Asset Sale Proceeds.”

When the aggregate amount of Excess Asset Sale Proceeds exceeds $10.0 million, the Company will be required under this Indenture to make an offer to the Holders of Notes issued thereunder and the holders of any other Senior Indebtedness that is subject to requirements with respect to the application of net proceeds from asset sales that are substantially similar to those contained in this Indenture (an “Asset Sale Offer”) to purchase on a pro rata basis (with the Excess Asset Sale Proceeds prorated between the Holders of the Notes and such holders of such other Senior Indebtedness based upon outstanding aggregate principal amounts) the maximum principal amount of the Notes and such other Senior Indebtedness that may be purchased or prepaid, as applicable, out of the prorated Excess Asset Sale Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest thereon to the date of purchase, in accordance with the procedures set forth in this Indenture. To the extent that the aggregate principal amount of Notes and other Senior Indebtedness tendered (and electing to be redeemed or repaid, as applicable) pursuant to an Asset Sale Offer is less than the Excess Asset Sale Proceeds, the Company and its Restricted Subsidiaries may use any remaining Excess Asset Sale Proceeds for general corporate purposes and any other purpose not prohibited by this Indenture. Upon completion of the offer to purchase, the amount of Excess Asset Sale Proceeds shall be reset at zero.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of the Company’s compliance with such securities laws or regulations.

Section 4.11 Transactions with Affiliates.

The Company 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 properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of any such Person (each of the foregoing, an “Affiliate Transaction”) unless:

(1) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that could have been obtained in a transaction by the Company or such Restricted Subsidiary with an unrelated Person; and

(2) the Company 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 its Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of its Board of Directors; and

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, an opinion as to the fairness to the Company and its Restricted Subsidiaries of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing.

provided, that none of the following shall be deemed to be Affiliate Transactions and therefore shall not be subject to the provisions of the preceding paragraph:

(1) any employment, equity award, equity option or equity appreciation agreement or plan, agreement or other similar compensation plan or arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of its business;

(2) transactions between or among (A) the Company and one or more Restricted Subsidiaries and (B) any Restricted Subsidiaries;

(3) the performance of any written agreement in effect on the Issue Date, as such agreement may be amended, modified or supplemented from time to time; provided, however, that any amendment, modification or supplement entered into after the Issue Date will be permitted only to the extent that its terms do not materially and adversely affect the rights of any Holders of the Notes (as determined in good faith by an officer of the Company, and, if such amendment, modification or supplement involves aggregate consideration in excess of $5.0 million, as determined in good faith by the Board of Directors) as compared to the terms of the agreement in effect on the Issue Date;

(4) loans or advances to officers, directors and employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures and other purposes, in each case, in the ordinary course of business;

(5) maintenance in the ordinary course of business of customary benefit programs or arrangements for employees, officers or directors, including vacation plans, health and life insurance plans, deferred compensation plans and retirement or savings plans and similar plans;

(6) fees and compensation paid to, and indemnity provided on behalf of, officers, directors, employees or consultants of the Company or any of its Restricted Subsidiaries in their capacity as such, to the extent such fees and compensation are reasonable and customary;

(7) sales of Equity Interests of the Company (other than Disqualified Stock) to Affiliates of the Company or any of its Restricted Subsidiaries; and

(8) Restricted Payments that are permitted by the provisions of this Indenture described above under Section 4.07.

Section 4.12 Liens.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien (other than Permitted Liens) upon any of its property or assets (including Capital Stock of a Restricted Subsidiary), whether owned on the Issue Date or acquired after that date, securing any Indebtedness, unless:

(1) in the case of Liens securing Subordinated Obligations of the Company or a Restricted Subsidiary, the Notes or Subsidiary Guarantees, as applicable, are contemporaneously secured by a Lien on such property or assets on a senior basis to the Subordinated Obligations so secured with the same priority that the Notes or Subsidiary Guarantees, as applicable, have to such Subordinated Obligations until such time as such Subordinated Obligations are no longer so secured by a Lien; and

(2) in the case of Liens securing Senior Indebtedness of the Company or a Restricted Subsidiary, the Notes or Subsidiary Guarantees, as applicable, are contemporaneously secured by a Lien on such property or assets on an equal and ratable basis with the Senior Indebtedness so secured until such time as such Senior Indebtedness is no longer so secured by a Lien.

Section 4.13 Corporate Existence.

Subject to Article 5 hereof, the Company 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 the Company or any such Subsidiary; and

(2) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company 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 the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company 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 4.14 Change of Control.

Upon the occurrence of a Change of Control, all Holders of Notes will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of the Notes pursuant to the offer described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will mail to each Holder of Notes a notice describing the transaction or transactions that constitute the Change of Control and offering to repurchase the Notes on the date specified in such notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required by this Indenture and described in such notice. The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.14 by virtue of the Company’s compliance with such securities laws or regulations.

With respect to any Change of Control Offer, on the Change of Control Payment Date, the Company will, to the extent lawful:

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

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

The Paying Agent will promptly mail to each Holder of Notes tendered pursuant to the Change of Control Offer the Change of Control Payment for such Notes, with such payments to be made through the facilities of DTC for all Notes in global form, and the Trustee, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, 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 the Holder; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The Company will not be required to make a Change of Control Offer with respect to the Notes upon a Change of Control if a third party makes the Change of Control Offer with respect to the Notes in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture that are applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. A Change of Control Offer may be made with respect to the Notes in advance of a Change of Control, and conditional upon the occurrence of such Change of Control, if a definitive agreement for the Change of Control is in place at the time of making of the Change of Control Offer.

With respect to the Notes, if Holders of not less than 95% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or such third party will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes that remain outstanding following such purchase at a price in cash equal to the applicable Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest thereon to the date of redemption.

Section 4.15 Payments for Consent.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Section 4.16 Additional Subsidiary Guarantees.

If, after the Issue Date, the Company or any of its Restricted Subsidiaries acquires or creates another Domestic Subsidiary, then that newly acquired or created Domestic Subsidiary must become a Guarantor and execute a supplemental indenture and deliver an Opinion of Counsel satisfactory to the Trustee within 20 Business Days of the date on which it was acquired or created.

The Company will not permit any of its Restricted Subsidiaries, directly or indirectly, to guarantee or pledge any assets to secure the payment of any other Indebtedness of the Company or any other Guarantor thereof unless such Restricted Subsidiary is a Guarantor or simultaneously becomes a Guarantor of the Notes and executes a supplemental indenture and delivers an Opinion of Counsel satisfactory to the Trustee, which Subsidiary Guarantee (i) if such other Indebtedness is a Subordinated Obligation, will be senior to such other guarantee with the same priority that the Notes or the Subsidiary Guarantees, as applicable, have to such Subordinated Obligation, and (ii) if such other indebtedness is Senior Indebtedness, will be pari passu with such other guarantee. The form of such supplemental indenture is attached as Exhibit F hereto.

Section 4.17 Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors may designate any Unrestricted Subsidiary to be a Restricted Subsidiary only if:

(1) immediately after giving effect to such designation, the Company could incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test under the first paragraph of Section 4.09;

(2) immediately before and immediately after giving effect to such designation, no Default or Event of Default shall have occurred and be continuing; and

(3) the Company certifies that such designation complies with this Section 4.17. Any such designation by the Board of Directors shall be evidenced by the Company promptly filing with the Trustee a copy of the resolution giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding provisions.

The Board of Directors may designate any Subsidiary of the Company to be an Unrestricted Subsidiary under the circumstances and pursuant to the requirements described in the definition of “Unrestricted Subsidiary,” which requirements include that such designation will be made in compliance with this Section 4.17. For purposes of making the determination as to whether such designation would be made in compliance with this Section 4.17, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be Restricted Payments at the time of such designation and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.07. All such outstanding Investments will be deemed to constitute Investments in an amount equal to the greater of (1) the net book value (determined in accordance with GAAP) of such Investments at the time of such designation and (2) the Fair Market Value of such Investments at the time of such designation.

(2) immediately before and after such transaction no Default or Event of Default has occurred and is continuing;

(3) except in the case of a consolidation or merger of the Company with or into a Restricted Subsidiary, or a sale, assignment, transfer, conveyance or other disposition of properties or assets to the Company or a Restricted Subsidiary, either (a) immediately after giving pro forma effect to such transaction as if such transaction had occurred at the beginning of the applicable four-quarter period, the Company or the resultant, transferee or surviving Person (if other than the Company) would have a Fixed Charge Coverage Ratio that is greater than the Fixed Charge Coverage Ratio of the Company immediately prior to such transaction, or (b) immediately after giving pro forma effect to such transaction as if such transaction had occurred at the beginning of the applicable four-quarter period, the Company or the resultant transferee or surviving Person (if other than the Company) would be able to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section 4.09; and

This Indenture will provide that upon any consolidation, combination or merger or any transfer of all or substantially all of the assets of the Company in accordance with the foregoing, in which the Company is not the surviving corporation, the surviving Person formed by such consolidation or into which the Company is merged or to which such conveyance or transfer is made will succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture and the Notes with the same effect as if such surviving Person had been named as such, and in the case of any transfer of all (but not less than all) of the assets of the Company in accordance with the foregoing, the Company will be released from all of its obligations under the Notes and this Indenture.

In addition, the Company may not, directly or indirectly, lease all or substantially all of its properties or assets, in one or more related transactions, to any other Person.

(1) the resulting, surviving or transferee Person will expressly assume all of the obligations of such Guarantor under its Subsidiary Guarantee and the Registration Rights Agreement pursuant to a supplemental indenture reasonably satisfactory to the Trustee;

(2) immediately after giving effect to such transaction (and treating any Indebtedness which becomes an obligation of the resulting, surviving or transferee Person as a result of such transaction as having been incurred by such Person at the time of such transaction), no Default or Event of Default will have occurred or be continuing; and

(3) the Company will have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental agreements (if applicable) comply with this Indenture;

provided, however, that the foregoing will not apply to any such consolidation or merger with or into, or conveyance, transfer or lease to, any Person if the resulting, surviving or transferee Person will not be a Subsidiary of the Company and the other terms of this Indenture, including such terms as included in Section 4.10, are complied with.

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

(B) results in the acceleration of such Indebtedness prior to its express maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates without duplication $10.0 million or more;

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

and the order or decree remains unstayed and in effect for 60 consecutive days; or

Section 6.02 Acceleration.

Notwithstanding Section 6.01, in the case of an Event of Default specified in clause (7) or (8) of Section 6.01 hereof, with respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company 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.

Upon any such declaration, the Notes shall become due and payable immediately.

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 of all the Notes, rescind an acceleration and its consequences hereunder, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal of, premium on, if any, interest or Additional Interest, if any, on the Notes that has become due solely because of the acceleration) have been cured or waived and the Trustee has been compensated for all amounts it is owed in connection with such Event of Default.

Section 6.03 Other Remedies.

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

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

In the case of an Event of Default specified in clause (5) of Section 6.01 hereof, such Event of Default and all consequences thereof (excluding, however, any resulting Payment Default) will be annulled, waived and rescinded with respect to the Notes, automatically and without any action by the Trustee or the Holders of the Notes, if within 60 days after such Event of Default first arose the Company delivers an Officers’ Certificate to the Trustee stating that (1) the Indebtedness or Guarantee that is the basis for such Event of Default has been paid or discharged, (2) the Holders of the Indebtedness have rescinded or waived the acceleration giving rise to such Event of Default or (3) the Default that is the basis for such Event of Default has been otherwise cured; provided, however, that in no event shall an acceleration of the principal amount of the Notes as described under Section 6.02, waived or rescinded upon the happening of any such events.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes, waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, interest or Additional Interest, if any, on, the Notes (including in connection with an offer to purchase); provided, the Trustee has been compensated for all amounts it is owed in connection with such Default or Event of Default.

Upon any such waiver pursuant to this Section 6.04, the corresponding Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

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

Section 6.06 Limitation on Suits.

No Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless:

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

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

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

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

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

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

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 of, premium on, if any, interest or Additional Interest, if any, on, the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

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 the Company for the whole amount of principal of, premium on, if any, interest and Additional Interest, if any, 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.

The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have 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 the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company 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 Subsidiary Guarantees) and this Indenture on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Subsidiary 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 Subsidiary Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, 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, premium on, if any, interest or Additional Interest, if any, on, such Notes when such payments are due (but not the Change of Control Payment or the payment pursuant to an Asset Sale Offer) from the trust referred to in Section 8.04 hereof;

(2) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof;

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

(4) this Article 8.

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

Section 8.03 Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company 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 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.14, 4.15, 4.16 and 4.17 hereof and clause (4) of Section 5.01 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 Subsidiary Guarantees, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Subsidiary Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under 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), (4), (5), (6) and (9) hereof will not constitute Events of Default.

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

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

(4) no Default or Event of Default shall have occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the incurrence of Indebtedness or the grant of Liens securing such Indebtedness, all or a portion of the proceeds of which will be applied to such deposit) or insofar as Defaults from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

(6) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally;

(8) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for 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 the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, interest and Additional Interest, if any, but such money need not be segregated from other funds except to the extent required by law.

The Company 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 the Company from time to time upon the request of the Company 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 firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under 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 Company.

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

Section 9.02 With Consent of Holders of Notes.

Except as provided in Section 9.01 and below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including, without limitation, Section 3.09, 4.10 and 4.14 hereof) and the Notes and the Subsidiary Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium on, if any, interest or Additional Interest, if any, on, the Notes, except a Payment Default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Subsidiary Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes).

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

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

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

(2) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes (except as provided with respect to Secitons 3.09, 4.10 and 4.14 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, premium on, if any, interest or Additional Interest, if any, 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, premium on, if any, interest or Additional Interest, if any, on, the Notes (except as permitted by clause (7) below in this Section 9.02);

(7) waive a redemption payment with respect to any Note (other than a payment required by Sections 3.09, 4.10 and 4.14 hereof); or

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

Section 9.03 Compliance with Trust Indenture Act.

Every amendment or supplement to this Indenture or the Notes will be set forth in a 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. The Company 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. The Company may not sign an amended or supplemental indenture until the Board of Directors of the Company 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 12.04 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

SUBSIDIARY GUARANTEES

Section 10.01. Guarantee.

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

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

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

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

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

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

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Subsidiary Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantee.

Section 10.02. Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03. Execution and Delivery of Subsidiary Guarantee.

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

Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 10.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee.

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

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

In the event that the Company 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, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.16 hereof and this Article 10, to the extent applicable.

Section 10.04. Guarantors May Consolidate, etc., on Certain Terms.

Except as otherwise provided in Section 10.05 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 the Company 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 10.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under its Subsidiary Guarantee, this Indenture and the Registration Rights Agreement on the terms set forth herein or therein, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee; or

(b) the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including without limitation, Section 4.10 hereof.

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee endorsed upon the Notes 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 Subsidiary Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof.

Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses 2(a) and (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 the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

Section 10.05. Releases.

The Subsidiary Guarantee of a Guarantor will be released:

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

(2) in connection with any sale or other disposition of all of the Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition complies with the applicable provisions of this Indenture, including without limitation Section 4.10 hereof. Upon delivery by the Company and the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company 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 Subsidiary Guarantee;

(3) if such Guarantor is a Restricted Subsidiary and the Company designates such Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture;

(4) upon Legal Defeasance or Covenant Defeasance pursuant to Article 8 or upon satisfaction and discharge of this Indenture pursuant to Article 11; or

(5) upon the liquidation or dissolution of such Guarantor provided that no Default or Event of Default has occurred and is continuing.

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

ARTICLE 11

SATISFACTION AND DISCHARGE

Section 11.01 Satisfaction and Discharge.

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

(1) either:

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

(b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the mailing of a notice of redemption or otherwise and the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, in the form of cash in United States dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, interest and Additional Interest, if any, to the date of stated maturity or redemption;

(2) in respect of subclause (b) of clause (1) of this Section 11.01, no Default or Event of Default has occurred and is continuing on the date of the deposit or will occur as a result of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit), and such deposit will not result in a breach or violation of, or constitute a default under, any other material instrument to which the Company is a party or by which the Company is bound;

(3) the Company has paid or caused to be paid all sums payable by it under this Indenture; and

(4) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at stated maturity or on the redemption date, as the case may be.

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

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this Section 11.01 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 11.02 Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 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 the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, if any, interest and Additional Interest, if any, for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 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, the Company’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 11.01 hereof; provided that if the Company has made any payment of principal of, premium on, if any, interest or Additional Interest, if any, on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

If a notice or communication is mailed in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it.

If the Company mails a notice or communication to Holders, it will mail a copy to the Trustee and each Agent at the same time.

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

(1) an Officers’ Certificate in form and substance reasonably satisfactory to the Trustee (which must include the statements set forth in Section 12.05 hereof) stating that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been satisfied; and

Each Holder of a Note by accepting the Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

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

(1) Interest. Global Geophysical Services, Inc., a Delaware corporation (the “Company”), promises to pay or cause to be paid interest on the principal amount of this Note at 10½% per annum from ________________, ___ until maturity and shall pay the Additional Interest, if any, payable pursuant to the Registration Rights Agreement referred to below. The Company will pay interest and Additional Interest, if any, semi-annually in arrears on May 1 and November 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 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 May 1, 2012. The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that is 1% higher than 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, if any (without regard to any applicable grace period), at the same rate to the extent lawful.

Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

To the extent that the aggregate principal amount of Notes and other Senior Indebtedness tendered (and electing to be redeemed or repaid, as applicable) pursuant to an Asset Sale Offer is less than the Excess Asset Sale Proceeds, the Company and its Restricted Subsidiaries may use any remaining Excess Asset Sale Proceeds for general corporate purposes and any other purpose not prohibited by this Indenture. Upon completion of the offer to purchase, the amount of Excess Asset Sale Proceeds shall be reset at zero.

Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased

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

In the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company 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. Upon such declaration, the Notes shall become 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 time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. Except in the case of a Default or Event of Default in payment of principal of, premium on, if any, interest or Additional Interest, if any, on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of 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 of all the Notes, rescind an acceleration and its consequences under the Indenture, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal of, premium on, if any, interest or Additional Interest, if any, on the Notes that has become due solely because of the acceleration) have been cured or waived. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

No director, officer, employee, manager, incorporator, member, partner or stockholder or other owner of Capital Stock of the Company or any of its Subsidiaries, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of a Note by accepting the Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

(18) CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.

In the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company 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. Upon such declaration, the Notes shall become immediately due and payable. 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 time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. Except in the case of a Default or Event of Default in payment of principal of, premium on, if any, interest or Additional Interest, if any, on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of 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 of all the Notes, rescind an acceleration and its consequences under the Indenture, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal of, premium on, if any, interest or Additional Interest, if any, on the Notes that has become due solely because of the acceleration) have been cured or waived. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

FORM OF SUPPLEMENTAL INDENTURE

TO BE DELIVERED BY SUBSEQUENT GUARANTORS

Supplemental Indenture (this “Supplemental Indenture”), dated as of ________________, among __________________ (the “Guaranteeing Subsidiary”), a subsidiary of Global Geophysical Services, Inc. (or its permitted successor), a Delaware corporation (the “Company”), the Company, the other Guarantors (as defined in the Indenture referred to herein) and The Bank of New York Mellon Trust Company, N.A., as trustee under the Indenture referred to below (the “Trustee”).

W I T N E S S E T H

WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of March 28, 2012 providing for the issuance of 10½% Senior Notes due 2017 (the “Notes”);

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

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

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

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

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

3. No Recourse Against Others. No director, officer, employee, manager, incorporator, member, partner or stockholder or other owner of Capital Stock of the Company or any of its Subsidiaries, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of a Note by accepting the Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws, and it is the view of the SEC that such a waiver is against public policy.
