(ii)                                  estimated proved oil and natural gas reserves of the Company and all Restricted Subsidiaries attributable to extensions, discoveries and other additions and upward revisions of estimates of proved oil and natural gas reserves (including previously estimated development costs incurred during the period and the accretion of discount since the prior period end) since the date of such year-end Reserve Report due to exploration, development or exploitation, production or other activities which would, in accordance with standard industry practice, cause such revisions;

and decreased by, as of the date of determination, the discounted future net revenue attributable to:

(iii)                               estimated proved oil and natural gas reserves of the Company and all Restricted Subsidiaries reflected in such Reserve Report produced or disposed of since the date of such year-end Reserve Report; and

(iv)                              reductions in estimated proved oil and natural gas reserves of the Company and all Restricted Subsidiaries reflected in such Reserve Report attributable to downward revisions of estimates of proved oil and natural gas reserves since such year-end due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions, in each case calculated on a pre-tax basis;

in the case of the preceding clauses (i) through (iv), calculated in accordance with SEC guidelines (utilizing the prices utilized in such Person’s year-end reserve  report) and estimated by the Company’s petroleum engineers or any independent petroleum engineers engaged by the Company for that purpose;

For purposes of this definition, whenever pro forma effect is to be given to a transaction, the pro forma calculations shall be made in good faith by the chief financial or chief accounting officer of the Company; provided that (x) such cost savings are reasonably identifiable, factually supportable, reasonably attributable to the action specified and reasonably anticipated to result from such actions and (y) such actions have been taken or initiated and the benefits resulting therefrom are anticipated by the Company to be realized within twelve (12) months, in each case, as certified in such officer’s certificate delivered to the trustee.  For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility, including, without limitation, the Revolving Credit Facility, computed with a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period.

The Securities

SECTION 2.02.                               Execution and Authentication.  One Officer shall sign the Securities for the Company by manual or facsimile signature.

If an Officer whose signature is on a Security no longer holds that office at the time the Authenticating Agent authenticates the Security, the Security shall be valid nevertheless.

26

A Security shall not be valid until an authorized signatory of the Authenticating Agent manually signs the certificate of authentication on the Security.  The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

On the Issue Date, the Authenticating Agent shall authenticate and deliver $450,000,000 of 9.750% Senior Notes Due 2020 and, at any time and from time to time thereafter, the Authenticating Agent shall authenticate and deliver Securities for original issue in an aggregate principal amount specified in such order, in each case upon a written order of the Company signed by two Officers.  Such order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and, in the case of an issuance of Additional Securities pursuant to Section 2.13 after the Issue Date, shall certify that such issuance is in compliance with Section 4.05.

The Trustee may appoint an authenticating agent (the “Authenticating Agent”) reasonably acceptable to the Company to authenticate the Securities.  Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so.  Each reference in this Indenture to authentication by the Authenticating Agent includes authentication by such agent.  An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.  The Trustee appoints Citibank as the initial Authenticating Agent.

The Authenticating Agent shall not be required to authenticate any Securities if the issue of such Securities pursuant to this Indenture shall affect the Authenticating Agent’s own rights, duties, protections, indemnities, or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonable acceptable to the Authenticating Agent.

The Trustee shall incur no liability for the appointment of any Authenticating Agent with respect to the Securities of one or more series or for any misconduct or negligence of such Authenticating Agent, including without limitation, its authentication of the Notes upon original issuance or pursuant to Section 2.13.

SECTION 2.03.                               Registrar and Paying Agent.

The Company shall maintain an office or agency (which may be the office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency (which may be the office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Securities may be presented for payment (the “Paying Agent”).  The Registrar shall keep a register of the Securities and of their transfer and exchange (the “Security Register”).  The Company may have one or more co-registrars and one or more additional paying agents.  The term “Paying Agent” includes any additional paying agent.

If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07.  The Company or any Restricted Subsidiary incorporated or organized within the United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent.

The Company initially appoints Citibank as Registrar and Paying Agent in connection with the Securities.  The Company initially appoints DTC to act as Depository with respect to the Global Securities.

In acting hereunder and in connection with the Securities, the Paying Agent and Registrar shall act solely as agents of the Company, and will not thereby assume any obligations towards or relationship of agency or trust for or with any Securityholder.

SECTION 2.04.                               Paying Agent to Hold Money in Trust.  The Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due.  Principal, premium, if any, and interest will be considered paid on the date due if the Paying Agent holds (as of 10:00 a.m., New York City time, on the due date) money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal and premium, if any, and interest, if any, then due; provided, however, that to the extent any such

27

funds are received by the Paying Agent from the Company after 10:00 a.m. New York City time on the due date, such funds will be distributed to the Holders within one Business Day of the receipt thereof.  The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Company in making any such payment.  If the Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund.  The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent.  Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.05.                               Securityholder Lists.  The Registrar shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders.  If the Trustee is not the Registrar, the Registrar shall furnish to the Trustee, at such 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 Securityholders.

SECTION 2.06.                               Transfer and Exchange.  A holder may transfer or exchange Securities in accordance with the provisions of this Indenture.  The Registrar may require a holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of Securities.  Holders shall be required to pay all taxes due on transfer or exchange.  The Company shall not be required to transfer or exchange any Security selected for redemption.  Also, the Company shall not be required to transfer or exchange any Security for a period of 15 days before a selection of Securities to be redeemed or between a record date and the next succeeding interest payment date.

SECTION 2.07.                               Replacement Securities.  If a mutilated Security is surrendered to the Registrar or if the holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and, upon the Company’s request, the Authenticating Agent shall authenticate, in lieu of any such lost, destroyed or stolen Security, a replacement Security of the same series and of like tenor and principal.  If required by the Registrar or the Company, such holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Registrar to protect the Company, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced.  If, after the delivery of such replacement Security, a bona fide purchaser of the original Security in lieu of which such replacement Security was issued presents for payment or registration such original Security, the Registrar shall be entitled to recover such replacement Security from the Person to whom it was delivered or any Person taking therefrom, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Company, the Trustee and any agent in connection therewith.

Upon the issuance of any new Security under this Section, the Company, the Paying Agent, or the Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Paying Agent and Registrar and their respective counsels) connected therewith.

Subject to the final sentence of the initial paragraph of this Section 2.07, every replacement Security shall constitute an original additional contractual obligation of the Company and any Guarantor and shall be entitled to all of the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

SECTION 2.08.                               Outstanding Securities.  Securities outstanding at any time are all Securities authenticated by the Authenticating Agent except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding.  A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Registrar and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code).

28

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09.                               Temporary Securities.  Until definitive Securities are ready for delivery, the Company may prepare and the Authenticating Agent shall, upon request of the Company, authenticate temporary Securities.  Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities.  Without unreasonable delay, the Company shall prepare and the Authenticating Agent shall, upon request of the Company, authenticate definitive Securities and deliver them in exchange for temporary Securities.  Until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series.

SECTION 2.10.                               Cancellation.  The Company at any time may deliver Securities to the Registrar for cancellation.  The Registrar and no one else shall cancel and dispose of all Securities surrendered for registration of transfer, exchange, payment or cancellation in accordance with its customary procedures.  Certification of such cancellation and/or destruction shall be delivered to the Company.  The Company may not issue new Securities to replace Securities they have redeemed, paid or delivered to the Registrar for cancellation.

SECTION 2.11.                               Defaulted Interest.  If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner at the rate provided in the Securities and Section 4.01.  The Company may pay the defaulted interest at the rate provided in the Securities and Section 4.01 to the persons who are Securityholders on a subsequent special record date.  The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Paying Agent and, at least 15 days before any such subsequent record date, shall promptly mail to each Securityholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

SECTION 2.12.                               CUSIP Numbers, ISINs, etc.  The Company in issuing the Securities may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case if then generally in use) and, if so, the Paying Agent shall use “CUSIP” numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.  The Company shall promptly advise the Paying Agent in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the Securities.

SECTION 2.13.                               Issuance of Additional Securities.  After the Issue Date, the Company shall be entitled, subject to its compliance with Section 4.05, to issue Additional Securities under this Indenture, which Securities shall have identical terms as the Securities issued on the Issue Date, other than with respect to the date of issuance and issue price.  All the Securities issued under this Indenture shall be treated as a single class for all purposes of this Indenture including waivers, amendments, redemptions and offers to purchase.

With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of Directors and an Officers’ Certificate, a copy of each which shall be delivered to the Paying Agent, the following information:

(1)                                  the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this Indenture and the provision of Section 4.05 that the Company is relying on to issue such Additional Securities; and

(2)                                  the issue price, the issue date and the CUSIP number of such Additional Securities; provided, however, that if Additional Securities are issued with the same CUSIP number as any other Securities previously issued under this Indenture, then such Additional Securities shall be issued at a price that

29

would not prevent such Additional Securities from being treated as fungible with such previously-issued Securities for U.S. federal income tax purposes.

ARTICLE 3

Redemption

SECTION 3.01.                               Notices to Trustee.  If the Company elects to redeem Securities pursuant to paragraph 5 of the Securities or pursuant to Section 4.09(h), it shall notify the Paying Agent in writing of the redemption date, the principal amount of Securities to be redeemed and the provision of the Securities or this Indenture pursuant to which the redemption will occur.

Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel from the Company to the effect that such redemption will comply with the conditions herein.

SECTION 3.02.                               Selection of Securities to Be Redeemed.  If less than all of the Securities are to be redeemed at any time, the Paying Agent shall select Securities for redemption on a pro rata basis (or, in the case of Securities issued in global form, based on a method as DTC may require) unless otherwise required by law or applicable stock exchange or depositary requirements.  No Securities of $2,000 or less may be redeemed in part.

SECTION 3.03.                               Notice of Redemption.  Notices of redemption shall be mailed by the Paying Agent by first class mail at least 30 but not more than 60 days before the redemption date to each holder of Securities 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 Securities or a satisfaction and discharge of this Indenture.  Notices of redemption may not be conditional, except (i) that any redemption pursuant to the second paragraph of Section 5 of the Securities, may, at the Company’s discretion, be subject to completion of the related Equity Offering and (ii) as described under Section 4.09.

The notice shall identify the Securities to be redeemed and shall state:

(1)                                  the redemption date;

(2)                                  the redemption price;

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

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

(5)                                  if less than all the outstanding Securities are to be redeemed, the identification and principal amounts of the particular Securities to be redeemed;

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

(7)                                  the “CUSIP” number, ISIN or “Common Code” number, if any, printed on the Securities being redeemed;

(8)                                  that no representation is made as to the correctness or accuracy of the “CUSIP” number, ISIN, or “Common Code” number, if any, listed in such notice or printed on the Securities; and

(9)                                  any conditions precedent applicable to the redemption.

At the Company’s request, upon written notice provided at least 45 days prior to the redemption date, the Paying Agent shall give the notice of redemption (with a copy to the Trustee) in the Company’s name and at the

30

Company’s expense.  In such event, the Company shall provide the Paying Agent with the information required by this Section and a copy of the notice of redemption to be mailed to the holders.

SECTION 3.04.                               Effect of Notice of Redemption.  Once notice of redemption is mailed, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, subject to the last sentence of this Section 3.04.  Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the related interest payment date), and such Securities shall be canceled by the Registrar.  Failure to give notice or any defect in the notice to any holder shall not affect the validity of the notice to any other holder.  Any redemption or notice of redemption may, at the Company’s option, be subject to one or more conditions precedent and, in the case of a redemption with the net cash proceeds of an Equity Offering, be given prior to the completion of the related Equity Offering.

SECTION 3.05.                               Deposit of Redemption Price.  At least one Business Day prior to the redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary of the Company is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of, premium, if any, and accrued interest on all Securities to be redeemed on that date other than Securities or portions of Securities called for redemption which have been delivered by the Company to the Registrar for cancellation.

SECTION 3.06.                               Securities Redeemed in Part.  Upon surrender of a Security that is redeemed in part only, the notice of redemption that relates to that Security shall state the portion of the principal amount of that Security that is to be redeemed and a new Security in principal amount equal to the unredeemed portion of the original Security shall be issued in the name of the holder of Securities upon cancellation of the original Security.  Securities called for redemption become due on the date fixed for redemption.  On or after the redemption date, interest ceases to accrue on Securities or portions of Securities so redeemed.

ARTICLE 4

Covenants

SECTION 4.01.                               Payment of Securities.  The Company shall promptly pay the principal of and interest on the Securities on the dates and in the manner provided in the Securities and in this Indenture.  Principal and interest shall be considered paid on the date due if on such date the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and interest then due.

(a)                                  Whether or not the Company is subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, to the extent not prohibited by the Exchange Act, the Company will file with the SEC, and make available to the Trustee and the holders of the Securities without cost to any holder, the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation within five Business Days following the time periods specified therein.  In the event that the Company is not permitted to file such reports, documents and information with the SEC pursuant to the Exchange Act, the Company shall nevertheless make available such Exchange Act information to the Trustee and the holders of the Securities without cost to any holder as if the Company were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act within the time periods specified therein with respect to a non-accelerated filer by posting such information on a freely accessible page of its website.

(b)                                 The Company shall be deemed to have furnished such reports and other information to the Trustee and the holders of Securities if it has filed such reports and other information with the SEC using the EDGAR filing system (or any successor filing system) or, if such system is not available to the Company, if it has filed such reports and other information on a freely accessible page of its website, and in each case, such reports and other information are publicly available thereon.

31

(c)                                  In addition, to the extent not satisfied by the foregoing, the Company shall agree that, for so long as any Securities are outstanding, it will furnish to holders of the Securities 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.

(e)                                  Delivery of any information, documents and reports to the Trustee pursuant to this Section 4.02 is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates.

SECTION 4.03.                               Taxes.  The Company will pay, and the Company 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 Securityholders.

SECTION 4.04.                               Restricted Payments.

(a)                                  The Company will not, and will not permit any Restricted Subsidiary 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 Restricted Subsidiary’s Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any Restricted Subsidiary) or to the direct or indirect holders of the Company’s or any Restricted Subsidiary’s Equity Interests in their capacity as such (other than (i) dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company, (ii) dividends or distributions payable to the Company or any Restricted Subsidiary or (iii) in the case of any dividend or distribution payable on or in respect of any class or series of Equity Interests issued by a Restricted Subsidiary other than a wholly owned Subsidiary, pro rata dividends or distributions to minority stockholders of such Restricted Subsidiary (or owners of an equivalent interest in the case of a Subsidiary that is an entity other than a corporation); provided that the Company or one of its Restricted Subsidiaries receives at least its pro rata share of such dividend or distribution in accordance with its Equity Interests in such class or series of securities));

(C)                                such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and all Restricted Subsidiaries since the date of this Indenture (excluding Restricted Payments permitted by Section 4.04(b)(2), (3), (4), (5), (6), (7), (8), and (10), is less than the sum, without duplication, of:

(i)                                     50% of the Consolidated Net Income for the period (taken as one accounting period) from April 1, 2012 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus

(3)                                  the repurchase, redemption, defeasance or other acquisition or retirement for value of any Existing Preferred Stock or Disqualified Stock with the net cash proceeds from a substantially concurrent incurrence of Permitted Refinancing Indebtedness or Indebtedness incurred pursuant Section 4.05(a), with a sale being deemed substantially concurrent if such repurchase, redemption, defeasance or other acquisition or retirement for value occurs not more than 35 days after such sale;

(d)                                 For purposes of determining compliance with this Section 4.04, in the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in clauses (1) through (11) of Section 4.04(b) or as a Permitted Investment, the Company shall be permitted to classify (or later

35

reclassify in its sole discretion) such Restricted Payment or Permitted Investment in any manner that complies with this Section 4.04, and such Restricted Payment or Permitted Investment shall be treated as having been made pursuant to only one of such clauses or of the definition of “Permitted Investment” in Section 1.01.

(a)                                  The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, create, incur, issue, assume, Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock and the Company will not, and will not permit any Restricted Subsidiary to issue any Preferred Stock; provided, however, that the Company may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and the Company and the Guarantors may incur Indebtedness (including Acquired Debt) or issue Preferred Stock, if the 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 such Preferred Stock is issued, as the case may be, would have been at least 2.25 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the Preferred Stock had been issued, as the case may be, at the beginning of such four-quarter period.

(b)                                 Section 4.05(a) shall not prohibit the incurrence of any of the following items of Indebtedness or issuances of Disqualified Stock or Preferred Stock, as applicable (collectively, “Permitted Debt”):

(2)                                  the incurrence by the Company or its Restricted Subsidiaries of the Existing Indebtedness (other than described in clause (1) or (3));

(3)                                  the incurrence by the Company and the Guarantors of Indebtedness represented by (a) the Securities and the related Note Guarantees to be issued on the date of this Indenture and (b) any Exchange Notes issued in exchange for such Securities (including any Guarantee thereof);

(4)                                  the incurrence by the Company or any Restricted Subsidiary of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation, repair or improvement of property, plant or equipment used in the business of the Company or any Restricted Subsidiary and related financing costs, and Attributable Debt in respect of sale and leaseback transactions, 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 Section 4.05(b)(4), not to exceed at any time outstanding the greater of (A) $25.0 million and (B) 2.0% of Adjusted Consolidated Net Tangible Assets;

(5)                                  the incurrence by the Company or any Restricted Subsidiary of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) or Disqualified Stock that was permitted by this Indenture to be incurred under Section 4.05(a) or clause (2), (3), (4), (5) or (17) of this Section 4.05(b);

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

36

(A)                              if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Securities, in the case of the Company, or the Note Guarantee, in the case of a Guarantor; and

(B)                                (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or any Restricted Subsidiary and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or any Restricted Subsidiary,

will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted at the time of such sale or transfer by this Section 4.05(b)(6);

(7)                                  the issuance by any Restricted Subsidiary to the Company or to any Restricted Subsidiary of any Preferred Stock; provided, however, that:

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

(B)                                any sale or other transfer of any such Preferred Stock to a Person that is not the Company or any Restricted Subsidiary,

will be deemed, in each case, to constitute an issuance of such Preferred Stock by such Restricted Subsidiary that was not permitted at the time of such sale or transfer by this Section 4.05(b)(7);

(8)                                  the incurrence by the Company or any Restricted Subsidiary of Hedging Obligations in the ordinary course of business or customary in the Oil and Gas Business;

(9)                                  the Guarantee by the Company or any Restricted Subsidiary of Indebtedness of the Company or any Restricted Subsidiary to the extent that the guaranteed Indebtedness was permitted to be incurred by another provision of this Section 4.05; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Securities, then the Guarantee must be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed;

(10)                            the incurrence by the Company or any Restricted Subsidiary of Indebtedness in respect of self-insurance obligations or the financing of insurance premiums, or bid, plugging and abandonment, appeal, reimbursement, performance, surety and similar bonds and completion guarantees provided by the Company or a Restricted Subsidiary in the ordinary course of business or customary in the Oil and Gas Business and any Guarantees or letters of credit functioning as or supporting any of the foregoing bonds or obligations and workers’ compensation claims in the ordinary course of business;

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

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

(13)                            the incurrence by the Company or any Restricted Subsidiary of take or pay agreements or in-kind obligations relating to net oil or natural gas balancing positions arising in the ordinary course of business or customary in the Oil and Gas Business;

(14)                            any obligation arising from agreements of the Company or any Restricted Subsidiary providing for indemnification, adjustment of purchase price, earn outs, or similar obligations, in each case,

37

incurred or assumed in connection with the disposition of any business, assets or Capital Stock of a Restricted Subsidiary in a transaction permitted by this Indenture, provided the maximum assumable liability in respect of all such Indebtedness shall at no time exceed the gross proceeds, including non-cash proceeds (the fair market value of such non-cash proceeds being measured at the time received and without giving effect to any subsequent changes in value), actually received by the Company and any Restricted Subsidiaries in connection with such disposition;

(15)                            the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness constituting reimbursement obligations with respect to letters of credit; provided that, upon the drawing of such letters of credit, such obligations are reimbursed within five Business Days of such drawing;

(16)                            the incurrence by any Foreign Subsidiary of Indebtedness that, in the aggregate together with all other Indebtedness of all Foreign Subsidiaries, including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness incurred pursuant to this clause (16), does not exceed the greater of (a) $25.0 million and (b) 1.5% of the Adjusted Consolidated Net Tangible Assets of all Foreign Subsidiaries, considered as a consolidated enterprise, determined as of the date of the incurrence of such Indebtedness after giving pro forma effect to such incurrence and the application of the proceeds therefrom; and

(17)                            the incurrence by the Company or any Guarantor of additional Indebtedness or the issuance by the Company of any Disqualified Stock or Preferred Stock in an aggregate principal amount (or accreted value, as applicable), including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred or Disqualified Stock or Preferred Stock issued pursuant to this clause (17), not to exceed at any time outstanding the greater of (i) $35.0 million and (ii) 2.0% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence or issuance.

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

(d)                                 For purposes of determining compliance with this Section 4.05, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in Section 4.05(b)(1) through (17), or is entitled to be incurred pursuant to Section 4.05(a), the Company will be permitted to divide, classify and reclassify such item of Indebtedness on the date of its incurrence, or later redivide or reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.05.  Indebtedness under Credit Facilities outstanding on the date on which Securities are first issued and authenticated under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt.  The accrual of interest or Preferred Stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness not secured by a Lien in the form of additional Indebtedness with the same terms, the reclassification of Preferred Stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Preferred Stock or Disqualified Stock in the form of additional securities of the same class of Preferred Stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Preferred Stock or Disqualified Stock for purposes of this Section 4.05; provided that the amount thereof is included in Fixed Charges as accrued to the extent required by the definition of such term.

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

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

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

38

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

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

(B)                                the amount of the related Indebtedness of the other Person.

SECTION 4.06.                               Restrictions on Distributions and Other Payments by Restricted Subsidiaries.

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

(1)                                  pay dividends or make any other distributions on its Capital Stock to the Company or any Restricted Subsidiary, or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Company or any Restricted Subsidiary; provided that the priority that any series of Preferred Stock of a Restricted Subsidiary has in receiving dividends or liquidating distributions before dividends or liquidating distributions are paid in respect of common stock of such Restricted Subsidiary shall not constitute a restriction on the ability to make dividends or distributions on Capital Stock for purposes of this Section 4.06;

(2)                                  make loans or advances to the Company or any Restricted Subsidiary; or

(3)                                  sell, lease or transfer any of its properties or assets to the Company or any Restricted Subsidiary.

(b)                                 Section 4.06(a) shall not apply to encumbrances or restrictions existing under or by reason of:

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

(2)                                  this Indenture, the Securities, the Note Guarantees, the Exchange Notes and any Guarantees thereof, or any other indentures governing debt securities issued by the Company or any Guarantor that are not materially more restrictive, taken as a whole, with respect to dividend, distribution or other payment restrictions and loan or investment restrictions than those contained in this Indenture, Securities and the Guarantors’ Note Guarantees as in effect on the date of this Indenture as determined in good faith by Company;

(3)                                  agreements governing Indebtedness permitted to be incurred under Section 4.05 and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the restrictions therein are not materially more restrictive, taken as a whole, than those contained in this Indenture, the Securities and the Note Guarantees or the Revolving Credit Facility as in effect on the date of this Indenture, as determined in good faith by the Company;

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

(5)                                  any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any Restricted Subsidiary as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person,

39

other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(6)                                  customary non-assignment provisions in Hydrocarbon purchase and sale or exchange agreements, joint operating agreements or similar operational agreements or contracts or in licenses, easements or leases, in each case, entered into in the ordinary course of business or customary in the Oil and Gas Business;

(7)                                  mortgage financings and purchase money obligations for property acquired in the ordinary course of business or customary in the Oil and Gas Business and Capital Lease Obligations that impose restrictions on the property purchased or leased of the nature described in Section 4.06(a)(3);

(8)                                  any agreement for the sale or other disposition of a Restricted Subsidiary that restricts distributions by that Restricted Subsidiary or sales of such Restricted Subsidiary’s assets pending its sale or other disposition;

(9)                                  Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced, as determined in good faith by the Company;

(10)                            Liens permitted to be incurred under the provisions of the covenant described under Section 4.10 that limit the right of the debtor to dispose of the assets subject to such Liens;

(11)                            provisions limiting the disposition, leasing, subleasing or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements, farm-in and farm-out agreements and other similar agreements (including agreements entered into in connection with a Restricted Investment) entered into (a) in the ordinary course of business or customary in the Oil and Gas Business or (b) with the approval of the Company’s Board of Directors, in each case, which limitation is applicable only to the assets that are the subject of such agreements;

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

(13)                            encumbrances or restrictions of the nature described in clause (3) of the preceding paragraph contained in agreements or instruments described in the definition of “Permitted Business Investments” or governing any Permitted Acquisition Indebtedness, so long as such agreement or instrument (a) was not entered into in contemplation of the acquisition, merger or consolidation transaction related thereto and (b) is not applicable to any Person, or the assets of any Person, other than the Person, or the assets or Subsidiaries of the Person, subject to such acquisition, merger or consolidation, so long as the agreement containing such restriction does not violate any other provisions of this Indenture;

(14)                            any agreement or instrument relating to any property or assets acquired after the date of this Indenture, so long as such encumbrance or restriction relates only to the property or assets so acquired and is not and was not created in anticipation of such acquisitions; and

(15)                            Hedging Obligations incurred from time to time.

SECTION 4.07.                               Asset Sales.

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

40

(1)                                  The Company (or a 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 aggregate consideration received in the Asset Sale by the Company or a Restricted Subsidiary and all other Asset Sales since the date of this Indenture is in the form of cash or Cash Equivalents.  For purposes of this provision, each of the following will be deemed to be cash:

(A)                              any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Securities or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation or indemnity agreement that releases the Company or such Restricted Subsidiary from or indemnifies against further liability;

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

(C)                                accounts receivable of a business retained by the Company or any of its Restricted Subsidiaries, as the case may be, following the sale of such business; provided that such accounts receivable (i) are not past due more than 90 days and (ii) do not have a payment date greater than 120 days from the date of the invoices creating such accounts receivable;

(D)                               any Capital Stock or assets of the kind referred to in Section 4.07(b)(2) or Section 4.07(b)(4); and

(E)                                 all other assets (except cash, Cash Equivalents and the liabilities and properties to the extent specified in the preceding clauses (a) through (d)) received for all Asset Sales since the date of this Indenture to the extent that the Fair Market Value of all such other assets does not exceed in the aggregate 10% of the Company’s Adjusted Consolidated Net Tangible Assets at the time of determination;

provided that in the case of any Asset Sale pursuant to a condemnation, appropriation or similar taking, including by deed in lieu of condemnation, such Asset Sale shall not be required to satisfy the requirements of items (1) and (2) above.  Notwithstanding the preceding, the 75% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the preceding provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation.

(b)                                 Within 365 days after the receipt of any Net Proceeds from an Asset Sale the Company (or any Restricted Subsidiary) may apply such Net Proceeds:

(1)                                  to prepay, repay, purchase, repurchase, redeem, reduce, defease or acquire or retire (i) Obligations under Secured Indebtedness of the Company or any Restricted Subsidiary, (ii) Obligations under Indebtedness of a Restricted Subsidiary that is not a Guarantor (other than Indebtedness owed to the Company or another Restricted Subsidiary) or (iii) Obligations under Senior Indebtedness (provided that if the Company or any Guarantor shall so reduce Obligations under unsecured Senior Indebtedness, the Company will equally and ratably reduce Obligations under the notes as provided under the second paragraph of Section 5 of the Securities, through open market purchases (provided that such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all holders of the notes to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, the pro rata

41

principal amount of notes), in each case other than Indebtedness owed to the Company or any Restricted Subsidiary

(2)                                  to acquire all or substantially all of the assets of, or any Capital Stock of, one or more other Persons primarily engaged in the Oil and Gas Business, if, after giving effect to any such acquisition of Capital Stock, such Person becomes a Restricted Subsidiary;

(3)                                  to make capital expenditures in respect of the Company’s or any Restricted Subsidiary’s Oil and Gas Business; or

(4)                                  to acquire other assets (other than Capital Stock) that are not classified as current assets under GAAP and that are used or useful in the Oil and Gas Business;

provided, that Section 4.07(b)(2) through (4) shall be deemed to be satisfied if a bona fide binding contract committing to make the investment, acquisition or expenditure referred to herein is entered into by the Company or any Restricted Subsidiary, as the case may be, with a Person other than an Affiliate of the Company within the time period specified in the preceding paragraph and such Net Proceeds are subsequently applied in accordance with such contract within six months following the date such agreement is entered into.

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

(c)                                  Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.07(b) shall constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, within ten Business Days thereof, the Company will make an offer (an “Asset Sale Offer”) to all holders of Securities and all holders of other Indebtedness that is pari passu with the Securities containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets to purchase, prepay or redeem, on a pro rata basis, the maximum principal amount of Securities and such other pari passu Indebtedness (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds.  The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase, prepayment or redemption, subject to the rights of holders of Securities on the relevant record date to receive interest due on the relevant interest payment date, and will be payable in cash.  If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any Restricted Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture.  If the aggregate principal amount of Securities tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds allocated to the purchase of Securities, the Paying Agent will select the Securities to be purchased on a pro rata basis (except that any Securities represented by a Security in global form will be selected as discussed in the Offering Memorandum under the section titled “Book-Entry, Delivery and Form” based on a method as DTC may require), based on the amounts tendered (with such adjustments as may be deemed appropriate by the Company so that only Securities in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased).  Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(d)                                 Notwithstanding Sections 4.07(a) to (c), the sale, conveyance or other disposition of all or substantially all of the properties and assets of the Company and the Restricted Subsidiaries, taken as a whole, will be governed by Section 4.09 and/or Section 5.01 and not by this Section 4.07.

(e)                                  The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Securities pursuant to an Asset Sale Offer.  To the extent that the provisions of any securities laws or regulations conflict with this Section 4.07 or compliance with this Section 4.07 would constitute a violation of any such laws or regulations, the Company shall comply with such applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.07 by virtue of such compliance.

42

SECTION 4.08.                               Transactions with Affiliates.

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

(1)                                  the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary (as applicable) than those that would have been obtained in a comparable 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 $20.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliated Transactions complies with this Section 4.08 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company, if any; and

(B)                                with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $35.0 million, an opinion as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction or series of related Affiliate Transactions from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing.

(b)                                 The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to Section 4.08(a):

(1)                                  any employment or consulting agreement, employee benefit plan, stock ownership or stock option plan, officer or director indemnification, compensation or severance agreement or any similar arrangement existing on the date of this Indenture and any entered into thereafter by the Company or any Restricted Subsidiary in the ordinary course of business or customary in the Oil and Gas Business and payments, awards, grants or issuances pursuant thereto;

(2)                                  loans or advances to employees of the Company or any Restricted Subsidiary made in the ordinary course of business in an aggregate principal amount not to exceed $2.0 million at any one time outstanding;

(3)                                  transactions between or among the Company and one or more Restricted Subsidiaries (or any entity that becomes a Restricted Subsidiary as a result of such transaction);

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

(5)                                  payment of customary fees and reimbursements of expenses and other benefits (pursuant to indemnity arrangements or otherwise) of officers, directors, employees or consultants of the Company, any Restricted Subsidiary or an Affiliate of the Company, including provisions of officers’ and directors’ liability insurance;

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

43

(7)                                  Permitted Investments or Restricted Payments that do not violate Section 4.04, including any transaction that would constitute a Restricted Payment but for the exclusions from the definition thereof;

(8)                                  any transaction between the Company or any of its Restricted Subsidiaries and any Person that would not otherwise constitute an Affiliate Transaction except for the fact that one director of such other Person is also a director of the Company or such Restricted Subsidiary, as applicable; provided that such director abstains from voting as a director of the Company or such Restricted Subsidiary, as applicable, on any matter involving such other Person;

(9)                                  pledges by the Company or any Restricted Subsidiary of the Company of Equity Interests in Unrestricted Subsidiaries for the benefit of lenders or other creditors of the Company’s Unrestricted Subsidiaries;

(10)                            transactions effected, and payments made, in accordance with the terms of the agreements as such agreements are in effect on the date of this Indenture, and, except in the case of agreements entered into during any time that this covenant is suspended in accordance with the terms of this Indenture, described in the Offering Memorandum under the caption “Certain Relationships and Related Transactions” or the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011 under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Related Party Transaction” and, in each case, any amendment or replacement of any of such agreements so long as such amendment or replacement agreement is not materially more disadvantageous taken as a whole, to the holders of the Securities than the agreement so amended or replaced, as determined in good faith by the Board of Directors of the Company;

(11)                            transactions with Unrestricted Subsidiaries, customers, clients, suppliers or purchasers or sellers of goods or services, or lessors or lessees of property, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture (a) which are, in the aggregate (taking into account all the costs and benefits associated with such transactions), not materially less favorable to the Company and its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate, in the reasonable determination of the Board of Directors of the Company or the senior management thereof, or are on terms at least as favorable as might reasonably have been obtained at such time from a Person that is not an Affiliate and (b) with respect to which the Company has complied Sections 4.08(a)(2)(A) or (B); and

(12)                            in the case of contracts for exploring for, producing, marketing, storing, treating or otherwise handling, gathering, processing or transporting Hydrocarbons, or activities or services reasonably related or ancillary thereto, or other operational contracts, any such contracts entered into in the ordinary course of business or customary in the Oil and Gas Business and otherwise in compliance with the terms of this Indenture (a) which are fair to the Company or any Restricted Subsidiary, in the reasonable determination of the Board of Directors of the Company or the senior management thereof, or are on terms at least as favorable as might reasonably have been obtained at such time from a Person that is not an Affiliate and (b) with respect to which the Company has complied with Sections 4.08(a)(2)(A) or (B).

SECTION 4.09.                               Change of Control.

(a)                                  If a Change of Control occurs, unless the Company at such time has given notice of redemption under the second paragraph of Section 5 of the Securities with respect to all outstanding Securities, each holder of Securities 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 that holder’s Securities pursuant to an offer (a “Change of Control Offer”) on the terms set forth in this Indenture.  In the Change of Control Offer, the Company will offer a payment in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of Securities repurchased, plus accrued and unpaid interest, if any, on the Securities repurchased to the date of purchase (the “Change of Control Purchase Date”), subject to the rights of holders of Securities on the relevant record date to receive interest due on the relevant interest payment date.

44

(b)                                 Within 30 days following any Change of Control, unless the Company at such time has given notice of redemption under the second paragraph of Section 5 of the Securities with respect to all outstanding Securities, or, at the Company’s option as set forth below, in advance of a Change of Control, the Company shall mail a notice to each holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Securities properly tendered prior to the expiration date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by this Indenture and described in such notice.  The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control.  To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of this Indenture by virtue of such compliance.

(c)                                  Promptly following the expiration of the Change of Control Offer, the Company shall, to the extent lawful, accept all Securities or portions of Securities properly tendered pursuant to the Change of Control Offer.  Promptly after such acceptance, the Company will, on the Change of Control Purchase Date:

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

(2)                                  deliver or cause to be delivered to the Registrar the Securities properly tendered and accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions of Securities being purchased by the Company pursuant to the Change of Control Offer.

(d)                                 The Paying Agent shall promptly mail or wire transfer to each holder of Securities properly tendered the Change of Control Payment for such Securities (or, if all the Securities are then in global form, make such payment through the facilities of DTC), and the Authenticating Agent shall promptly authenticate and mail (or cause to be transferred by book entry) to each such holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any.  The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date.

(e)                                  On the Change of Control Payment Date, all Securities purchased by the Company under this Section 4.09 shall be delivered by the Company to the Registrar for cancellation, and the Company shall pay the Change of Control Payment to the holders entitled thereto.

(f)                                    The Company shall not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Securities properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to this Indenture and pursuant to Section 5 of the Securities unless and until there is a default in payment of the applicable redemption price.  Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

(g)                                 Securities repurchased by the Company pursuant to a Change of Control Offer will have the status of Securities issued but not outstanding or will be retired and cancelled, at the option of the Company.  Securities purchased by a third party pursuant to clause (1) of Section 4.09(f) will have the status of Securities issued and outstanding.

(h)                                 In the event that holders of not less than 90% in aggregate principal amount of the outstanding Securities accept a Change of Control Offer and the Company (or any third party making such Change of Control Offer in lieu of the Company pursuant to clause (1) of Section 4.09(f)) purchases all of the Securities held by such holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more

45

than 30 days following the purchase pursuant to the Change of Control Offer, to redeem all of the Securities that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, on the Securities that remain outstanding, to the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

SECTION 4.10.                               Liens.

(a)                                  The Company will not, and will not permit any Restricted Subsidiary to, create, incur, assume or otherwise cause or permit to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness (including Attributable Debt) upon any of their property or assets, now owned or hereafter acquired, unless all payments due to the holders under this Indenture and the Securities are secured on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien.

(b)                                 Any Lien on any assets of the Company or any Restricted Subsidiary created for the benefit of the holders of the Securities pursuant to Section 4.10(a) shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged at such time as there are no other Liens of any kind (other than Permitted Liens) on such assets securing Indebtedness.

SECTION 4.11.                               [Reserved].

SECTION 4.12.                               Additional Guarantees.  The Company shall not permit any of its Restricted Subsidiaries that are not then Guarantors to either (a) guarantee the payment of any Indebtedness of the Company or any other Guarantor or (b) incur any Indebtedness, in each case, under any Credit Facility pursuant to Section 4.05(b)(1), in each case, unless such Subsidiary becomes a Guarantor by executing a supplemental indenture and a joinder or supplement to the Registration Rights Agreement and delivering an opinion of counsel satisfactory to the Trustee and the Paying Agent within 30 Business Days after the date that Subsidiary was acquired or created or on which it guaranteed such Indebtedness.  The Company may elect, in its sole discretion, to cause any Subsidiary that is not otherwise required to be a Guarantor to become a Guarantor.

SECTION 4.13.                               [Reserved].

SECTION 4.14.                               Designation of Restricted and Unrestricted Subsidiaries.

(a)                                  The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default.  If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company or the Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be either an Investment made as of the time of the designation that will reduce the amount available for Restricted Payments under Section 4.04 or represent a Permitted Investment under one or more clauses of the definition of Permitted Investments, as determined by the Company.  Such designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

(b)                                 Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.04.  If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under the covenant described under Section 4.05, the Company will be in default of such covenant.

(c)                                  The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will

46

only be permitted if (1) such Indebtedness is permitted under Section 4.05, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period; and (2) no Default or Event of Default would be in existence following such designation.

SECTION 4.15.                               Compliance Certificate.  The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company a statement regarding compliance with this Indenture to the best of the knowledge of the signatories thereto.  Within 30 days of any officer of the Company becoming aware of any Default or Event of Default, the Company shall deliver to the Trustee and the Paying Agent a statement specifying such Default or Event of Default.

SECTION 4.16.                               Suspension of Certain Covenants when Securities Are Rated Investment Grade.

(a)                                  If on any date following the date of this Indenture:

(1)                                  the Securities are rated by both of the Rating Agencies as having an Investment Grade Rating; and

(2)                                  no Default or Event of Default shall have occurred and be continuing,

then, upon the Company’s delivery of notice of such events to the Trustee, the covenants described in Sections 4.04, 4.05, 4.06, 4.07, 4.08, 4.14, 5.01(a)(4) and 4.12 are suspended.

(b)                                 During any period that the covenants described in Sections 4.04, 4.05, 4.06, 4.07, 4.08, 4.14 5.01(a)(4) and 4.12 have been suspended, the Company’s Board of Directors may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to the covenant described in Section 4.14.

(c)                                  Notwithstanding the foregoing, if the rating assigned by either Rating Agency should subsequently decline to below Investment Grade Rating, the covenants described in Sections 4.04, 4.05, 4.06, 4.07, 4.08, 4.14, 5.01(a)(4) and 4.12 will be reinstituted as of and from the date of such rating decline (the “Reversion Date”).  In the event of any such reinstatement, no Default or Event of Default will be deemed to have occurred as a result of a failure to comply with the suspended covenants during a suspension period (or on the Reversion Date or after the suspension period based solely on events that occurred during the suspension period).  On each Reversion Date, all Indebtedness incurred during the suspension period prior to such Reversion Date will be deemed to be Permitted Indebtedness under Section 4.05(b)(3).  Calculations under the reinstated covenant described in 4.04 will be made as if the Restricted Payments had been in effect since the date of this Indenture, except that no Default will be deemed to have occurred solely by reason of a Restricted Payment made while the covenant described in Section 4.04 was suspended.  In addition, for the purposes of Sections 4.06 and 4.08, all agreements and arrangements entered into during the period in which such covenants are suspended shall be deemed to have been entered into and existing prior to the date of this Indenture.  For purposes of Section 4.07, on the Reversion Date, the unutilized Excess Proceeds amount will be reset to zero.

SECTION 4.17.                               Stay, Extension and Usury Laws.  Each of the Company and the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and each of the Company and 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 and the Paying Agent, but will suffer and permit the execution of every such power as though no such law has been enacted.

(b)                                 The Company may not, directly or indirectly:  (1) consolidate or merge with or into another Person (whether or not the Company is the survivor), or (2) sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person, unless:

(1)                                  either:  (A) the Company is the surviving Person; or (B) the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made is an entity organized or existing under the laws of the United States, any state of the United States or the District of Columbia;

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

(3)                                  immediately after such transaction, no Default or Event of Default exists;

(4)                                  except in the case of a consolidation or merger of the Company with or into a Guarantor, or a sale, assignment, transfer, conveyance, lease or other disposal to a Guarantor, immediately after giving effect to such transaction and any related financing transaction on a pro forma basis as if the same had occurred at the beginning of the applicable four-quarter period, either (a) the Company, would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the  Fixed Charge Coverage Ratio test set forth in Section 4.05(a) or (b) the Fixed Charge Coverage Ratio of the Company equal to or greater than the Fixed Charge Coverage Ratio of Company immediately prior to such transaction; and

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

This Section 5.01(b) shall not apply to any sale, assignment, transfer, conveyance, lease or other disposition of assets by any Restricted Subsidiary to the Company.  Sections 5.01(b)(3) and 5.01(a)(4) shall not apply to (1) any merger or consolidation of any Restricted Subsidiary into the Company or (2) any merger or consolidation of the Company with or into an Affiliate solely for the purpose of reorganizing the Company in another jurisdiction.

SECTION 5.02.                               The Guarantors May Consolidate, Etc. only on Certain Terms.  A Guarantor may not sell or otherwise dispose of, in one or more related transactions, all or substantially all of its properties or assets to, or consolidate with or merge with or into (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 or series of transactions, no Default or Event of Default exists; and

(2)                                  either:

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

(B)                                such transaction or series of transactions does not violate Section 4.07.

Notwithstanding the foregoing, any Guarantor may (A) consolidate with, merge into or sell, assign, transfer, convey, lease or otherwise dispose of all or part of its properties and assets to the Company or to another Guarantor or (B) dissolve, liquidate or windup its affairs if at that time it does not hold any material assets.

ARTICLE 6

Defaults and Remedies

SECTION 6.01.                               Events of Default.  Each of the following is an “Event of Default”:

(1)                                  default for 30 days in the payment when due of interest and Additional Interest, if any, on the Securities;

(2)                                  default in the payment when due (at stated maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the Securities;

(3)                                  failure by  the Company to comply with Sections 4.09 and Article 5;

(4)                                  failure by the Company or any Restricted Subsidiary for 60 days after notice to the Company by the Trustee or the holders of at least 25% in aggregate principal amount of the Securities then outstanding to comply with any of the other agreements in this Indenture;

(5)                                  default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any Restricted Subsidiary (or the payment of which is guaranteed by the Company or any Restricted Subsidiary), whether such Indebtedness or Guarantee now exists, or is created after the date of this Indenture, if that default:

(A)                              is caused by a failure to pay principal of, premium on, if any, or interest, if any, on, such Indebtedness when due after giving effect to any grace period provided in such Indebtedness (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 $20.0 million or more; provided, however, if, prior to any acceleration of the Securities, (i) any such Payment Default is cured or waived, (ii) any such acceleration is rescinded, or (iii) such Indebtedness is repaid during the 10 Business Day period commencing upon the end of any applicable grace period for such Payment Default or the occurrence of such acceleration, as the case may be, any Default or Event of Default (but not any acceleration of the Securities) caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission does not conflict with any judgment, decree or applicable law;

(6)                                  failure by the Company or any Restricted Subsidiary to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $20.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed, for a period of 60 days;

(7)                                  except as permitted by this Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, denies or disaffirms its obligations under its Note Guarantee;

(8)                                  the Company or any Restricted Subsidiary that is a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

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

49

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

(C)                                makes a general assignment for the benefit of its creditors;

or takes any comparable action under any foreign laws relating to insolvency, but excluding any of the above for the purposes of a solvent reconstruction, amalgamation or winding-up in connection with a transfer of assets solely to the Company or any Guarantor or a scheme of arrangement that does not result in the liquidation, provisional liquidation, winding-up or dissolution of the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary (unless the assets of the Restricted Subsidiary are transferred to the Company or a Guarantor);

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

(A)                              is for relief against the Company, any Guarantor, any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary in an involuntary case;

(B)                                appoints a Securities Custodian of the Company, any Guarantor, any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, or for any substantial part of its or their property; or

(C)                                orders the winding-up or liquidation of the Company, any Guarantor, any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary;

or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 60 days, and in relation to clauses (B) and (C), excluding any of the above clauses (B) and (C) for the purposes of a solvent reconstruction, amalgamation or winding-up in connection with a transfer of assets solely to the Company or any Guarantor or a scheme of arrangement that does not result in the liquidation, provisional liquidation, winding-up or dissolution of the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary (unless the assets of the Restricted Subsidiary are transferred to the Company or a Guarantor);

The foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

However, a default under clause (4) of this Section 6.01 will not constitute an Event of Default until the Trustee or the Holders of 25% in principal amount of the outstanding Securities notify the Company of the default and the Company or any Restricted Subsidiaries do not cure such default within the time specified after receipt of such notice.  Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.”

SECTION 6.02.                               Acceleration.  In the case of an Event of Default specified in Section 6.01 (8) or (9), with respect to the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, all outstanding Securities will become due and payable immediately without further action or notice.

50

If any other Event of Default occurs and is continuing, and is known to the Trustee, the Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding Securities may declare all the Securities to be due and payable immediately.

The Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may rescind any such acceleration with respect to the Securities and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration.  No such rescission shall affect any subsequent Default or impair any right consequent thereto.

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 or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding.  A delay or omission by the Trustee or any Securityholder 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.  No remedy is exclusive of any other remedy.  All available remedies are cumulative, to the extent permitted by law.

No right or remedy herein conferred upon or reserved to the Trustee or the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.  The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, then and in every such case the Company, the Trustee and the Holders shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 6.04.                               Waiver of Past Defaults.  The holders of a majority in aggregate principal amount of the then outstanding Securities by written notice to the Trustee may, on behalf of the holders of all of the Securities, rescind an acceleration or waive any existing Default or Event of Default and its consequences under this Indenture, if the rescission would not conflict with any judgment or decree, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or interest, if any, on, the Securities.  When a Default or Event of Default is waived, it is deemed cured, but not such waiver shall extend to any subsequent or other Default or impair any consequent right.

SECTION 6.05.                               Control by Majority.  The holders of a majority in principal amount of the then outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee.  However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of other Securityholders or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

SECTION 6.06.                               Limitation on Suits.  Subject to Article 7, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any holders of Securities unless such holders have offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense.  Except to enforce the right to receive payment of principal, premium, if any, or interest or Additional Interest, if any, when due, no holder of a Security may pursue any remedy with respect to this Indenture or the Securities unless:

51

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

(2)                                  holders of at least 25% in aggregate principal amount of the then outstanding Securities 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 Securities do not give the Trustee a direction inconsistent with such request.

A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder.  In the event that the Definitive Securities are not issued to any beneficial owner promptly after the Registrar has received a request from the Holder of a Global Security to issue such Definitive Securities to such beneficial owner of its nominee, the Company expressly agrees and acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to this Indenture, the right of such beneficial holder of Securities to pursue such remedy with respect to the portion of the Global Security that represents such beneficial holder’s Securities as if such Definitive Securities had been issued.

SECTION 6.07.                               Rights of Holders to Receive Payment.  Notwithstanding any other provision of this Indenture, the right of any holder to receive payment of principal of, premium, if any, and interest or Additional Interest, if any, on the Securities held by such holder, on or after the respective due dates expressed in the Securities, 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) occurs and is continuing, the Trustee may recover judgment in its own name and as Trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07.

SECTION 6.09.                               Trustee May File Proofs of Claim.  The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Securityholders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on behalf of the holders in any election of a Trustee in bankruptcy or other Person performing similar functions, and any Securities Custodian in any such judicial proceeding is hereby authorized by each holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07.

Nothing in this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

The Trustee shall be entitled to participate as a member of any official committee of creditors in the matters it deems advisable.

SECTION 6.10.                               Priorities.  If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

52

FIRST:  to the Trustee and the Paying Agent pro rata for amounts due under Section 7.07;

SECOND:  to Securityholders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and

THIRD:  to the Company or to such party as a court of competent jurisdiction shall direct, including a Guarantor, if applicable.

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section.  At least 15 days before such record date, the Company shall mail to each Securityholder and the Trustee a notice that states the record date, the payment date and amount to be paid.

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

SECTION 6.12.                               Waiver of Stay or Extension Laws.  Each of the Company and the Guarantors (to the extent it may lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and each of the Company and the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 7

Trustee

SECTION 7.01.                               Duties of Trustee.

(a)                                  If an Event of Default has occurred and is continuing, the Trustee, once it becomes aware of any such Event of Default, shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

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

(1)                                  the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2)                                  in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture.  However, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but shall not be required to verify any mathematical calculations contained therein).

53

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

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

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

(g)                                 No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(h)                                 Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section and to the provisions of the Trust Indenture Act.

(g)                                 The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, security, other evidence of indebtedness or other paper or document.

(m)                               The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be compensated and indemnified, are extended to, and shall, to the extent they are applicable to Citibank in the performance of its respective capacities provided for in this Indenture, be enforceable by Citibank, in each of its respective capacities hereunder, including its capacity as Paying Agent, Registrar and Authenticating Agent.

SECTION 7.03.                               Individual Rights of Trustee.  The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.  Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights.  However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04.                               Trustee’s Disclaimer.  The Trustee shall not be responsible for and makes no representation as to the validity, sufficiency or adequacy of this Indenture or the Securities or any disclosure material distributed with respect to any series of Securities; it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible or liable for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

SECTION 7.05.                               Notice of Defaults.  If a Default occurs, is continuing and is actually known to the Trustee, the Trustee shall mail to each Securityholder notice of the Default within 90 days after it occurs unless such Default shall have been cured or waived.  Except in the case of a Default in the payment of principal of, premium, if any, or interest on any Security, the Trustee may withhold from Securityholders notice of any continuing Default if it determines that withholding notice is in the interest of the holders.

55

SECTION 7.06.          Reports by Trustee to Holders.  As promptly as practicable after each May 15, beginning with the May 15 following the date of this Indenture, and in any event prior to July 15 in each year, the Trustee shall mail to each Securityholder a brief report dated as of May 15 that complies with Trust Indenture Act § 313(a), if such report is required by Trust Indenture Act § 313.  The Trustee shall also comply with Trust Indenture Act § 313(b) and (d).

SECTION 7.07.          Compensation and Indemnity.  The Company shall pay to the Trustee from time to time such compensation for its services as agreed by the Company and the Trustee.  The Trustee’s compensation shall not be limited by any law on compensation of a Trustee of an express trust.  The Company shall reimburse the Trustee upon request for all reasonable and documented out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services.  Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts.  The Company shall indemnify the Trustee and its officers, directors, employees and agents against any and all loss, liability, damage, claim or expense (including attorneys’ fees and expenses) including the costs and expenses of enforcing this Indenture against the Company and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any holder or any other Person) incurred by it in connection with the administration of this Indenture and the performance of its duties hereunder.  The Trustee shall notify the Company promptly of any claim for which it may seek indemnity.  Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder.  The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel.  The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct or negligence.  Any settlement which affects the Trustee may not be entered into without the written consent of the Trustee, unless the Trustee is given a full and unconditional release from liability with respect to the claims covered thereby and such settlement does not include a statement or admission of fault, culpability or failure to act by or on behalf of the Trustee.

To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.  The Trustee’s right to receive payment of any amounts due under this Section 7.07 shall not be subordinate to any other liability or Indebtedness of the Company.

The Company’s payment obligations pursuant to this Section shall survive the discharge of this Indenture and the resignation or removal of the Trustee.  When the Trustee incurs expenses after the occurrence of an Event of Default specified in Section 6.01(8) or (9) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

SECTION 7.08.          Replacement of Trustee.  The Trustee may resign at any time by so notifying the Company.  The holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee.  The Company may remove the Trustee if:

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

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

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

(4)           the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed by the Company or by the holders of a majority in principal amount of the Securities and such holders do not reasonably and promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

56

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company.  Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture.  The successor Trustee shall mail a notice of its succession to Securityholders.  The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the holders of 10% in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

SECTION 7.09.          Successor Trustee by Merger.  If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or entity, the resulting, surviving or transferee corporation or entity without any further act shall be the successor Trustee.

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

SECTION 7.10.          Eligibility; Disqualification.  The Trustee shall at all times satisfy the requirements of Trust Indenture Act § 310(a).  The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition.  The Trustee shall comply with Trust Indenture Act § 310(b); provided, however, that there shall be excluded from the operation of the Trust Indenture Act § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Trust Indenture Act § 310(b)(1) are met.

SECTION 7.11.          Preferential Collection of Claims Against the Company.  The Trustee shall comply with Trust Indenture Act § 311(a), excluding any creditor relationship listed in Trust Indenture Act § 311(b).  A Trustee who has resigned or been removed shall be subject to Trust Indenture Act § 311(a) to the extent indicated.

SECTION 8.02.          Conditions to Defeasance.  In order to exercise either Legal Defeasance or Covenant Defeasance:

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

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

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

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

58

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

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

SECTION 8.03.          Application of Trust Money.  The Paying Agent shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article 8.  It shall apply the deposited money and the money from U.S. Government Obligations to the payment of principal of and interest on the Securities in accordance with this Indenture.

SECTION 8.04.          Repayment to the Company.  The Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by them at any time.

Subject to any applicable abandoned property law, the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look to the Company for payment as general creditors.

SECTION 8.05.          Indemnity for Government Obligations.  The Company shall pay and shall indemnify the Trustee and the Paying Agent against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations other than such tax, fee or other charge which by law is for the account of the holders of the outstanding Securities.

SECTION 8.06.          Reinstatement.  If the Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court of competent jurisdiction or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and each Guarantor’s obligations under this Indenture with respect to the Securities and each Guarantee shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided, however, that, if the Company has made any payment of interest on, premium, if any, or principal of any Securities because of the reinstatement of their obligations, the Company shall be subrogated to the rights of the holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Paying Agent.

ARTICLE 9

After an amendment under this Section becomes effective, the Company shall mail to holders of the Securities a notice briefly describing such amendment.  The failure to give such notice to all holders of the Securities, or any defect therein, shall not impair or affect the validity of an amendment under this Section.

SECTION 9.02.          With Consent of Holders.  This Indenture, the Securities or the Note Guarantees may be amended or supplemented with the consent of the holders of a majority in aggregate principal amount of the then outstanding Securities (including, without limitation, additional Securities, 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 Securities), and any existing Default or Event of Default or compliance with any provision of this Indenture, the Securities or the Note Guarantees may be waived with the consent of the holders of a majority in aggregate principal amount of the then outstanding Securities (including, without limitation, additional Securities, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities).  However, without the consent of each holder of Securities affected, an amendment, supplement or waiver may not (with respect to any Securities held by a non-consenting holder):

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

(2)           reduce the principal of or change the fixed maturity of any Security or alter or waive any of the provisions with respect to the redemption or repurchase of the Securities (except Section 4.09);

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

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

(10)         make any change to or modify the ranking of the Securities.

It shall not be necessary for the consent of the holders under this Section to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof.

After an amendment under this Section becomes effective, the Company shall mail to Securityholders a notice briefly describing such amendment.  The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section.

SECTION 9.03.          Reserved.

SECTION 9.04.          Revocation and Effect of Consents and Waivers.  A consent to an amendment or a waiver by a holder of a Security shall bind the holder and every subsequent holder of that Security or portion of the Security that evidences the same debt as the consenting holder’s Security, even if notation of the consent or waiver is not made on the Security.  However, any such holder or subsequent holder may revoke the consent or waiver as to such holder’s Security or portion of the Security if the Trustee and the Paying Agent each receives the notice of revocation before the date the amendment or waiver becomes effective.  After an amendment or waiver becomes effective, it shall bind every Securityholder.  An amendment or waiver becomes effective in accordance with its terms.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture.  If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be holders after such record date.  No such consent shall be valid or effective for more than 120 days after such record date.

SECTION 9.05.          Notation on or Exchange of Securities.  If an amendment changes the terms of a Security, the Paying Agent may require the holder of the Security to deliver it to the Registrar.  The Registrar may place an appropriate notation on the Security regarding the changed terms and return it to the holder.  Alternatively, if the Company or the Paying Agent so determine, the Company in exchange for the Security shall issue and the Authenticating Agent shall authenticate a new Security that reflects the changed terms.  Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment.

SECTION 9.06.          Trustee and Paying Agent to Sign Amendments.  The Trustee and Citibank, in each of its respective capacities, shall sign any amendment authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee and Citibank, in each of its respective capacities, as applicable.  If it does, the Trustee and Citibank, in each of its respective capacities, may but need not sign it.  In signing such amendment the Trustee and Citibank in each of its respective capacities shall receive indemnity satisfactory to it and shall receive, and (subject to Section 7.01) shall be fully protected in conclusively relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

ARTICLE 10

Guarantees

SECTION 10.01.    Guarantees.

(a)           Each Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally on an unsecured basis, to each holder and to the Trustee and its successors and assigns (1) the full and punctual payment of principal of, premium on, and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture and the Securities and (2) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”).  Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Guarantor and that such Guarantor shall remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation.

(b)           To the fullest extent allowed by applicable law, each Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment.  To the fullest extent allowed by applicable law, each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations.  The obligations of each Guarantor hereunder shall not be affected by:  (1) the failure of any holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person (including any Guarantor) under this Indenture, the Securities or any other agreement or otherwise; (2) any extension or renewal of any thereof; (3) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (4) the release of any security held by any holder or the Trustee or Paying Agent for the Guaranteed Obligations or any of them; (5) the failure of any holder or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (6) except as set forth in Section 10.06, any change in the ownership of such Guarantor.

Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and (to the extent it may lawfully do so) waives any right to require that any resort be had by any holder or the Trustee to any security held for payment of the Guaranteed Obligations.

(c)           To the fullest extent allowed by applicable law, except as expressly set forth in Sections 8.01(b), 10.02 and 10.06, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise.  Without limiting the generality of the foregoing, to the fullest extent allowed by applicable law, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

(d)           Each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, premium on, or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

(e)           In furtherance of the foregoing and not in limitation of any other right which any holder or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay the principal of, premium on, or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation,

each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the holders or the Paying Agent an amount equal to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Company to the holders and the Paying Agent.

(f)            Each Guarantor further agrees that, as between it, on the one hand, and the holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations hereby may be accelerated as provided in Article 6 for the purposes of such Guarantor’s Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section.

(g)           Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any holder in enforcing any rights under this Section.

SECTION 10.02.        Limitation on Liability.  Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

SECTION 10.03.        Successors and Assigns.  This Article 10 shall be binding upon each Guarantor and its successors and permitted assigns and shall inure to the benefit of the successors and permitted assigns of the Trustee and the holders and, in the event of any transfer or assignment of rights by any holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 10.04.        No Waiver.  Neither a failure nor a delay on the part of either the Trustee or the holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege.  The rights, remedies and benefits of the Trustee and the holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise.

SECTION 10.05.        Modification.  No modification, amendment or waiver of any provision of this Article 10, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee and the Paying Agent, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.  No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 10.06.        Release of Guarantor.  A Guarantor shall be released from its obligations under this Article 10 (other than any obligation that may have arisen under Section 10.07) without the consent of any holders:

(a)           in connection with any sale or other disposition of all or substantially all of the properties or assets of that Guarantor, by way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transaction) the Company or any Restricted Subsidiary, if the sale or other disposition does not violate Section 4.07;

(b)           in connection with any sale or other disposition of the Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or any Restricted Subsidiary, if the sale or other disposition does not violate Section 4.07 and the Guarantor ceases to be a Restricted Subsidiary as a result of the sale or other disposition;

63

(c)           if the Company designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture;

(d)           if the Indebtedness which resulted in the obligations to Guarantee the Securities pursuant to Section 4.12 is repaid;

(e)           upon the liquidation or dissolution of any Guarantor that does not constitute a Default or Event of Default;

(f)            in the case of any Restricted Subsidiary which after the date of this Indenture is required to guarantee the Securities pursuant to Section 4.12, the release or discharge of the guarantee by such Restricted Subsidiary of all of the Indebtedness of the Company or any Guarantor or the repayment of all of the Indebtedness which resulted in the obligation to guarantee the Securities; or

(g)           upon legal defeasance, covenant defeasance or satisfaction and discharge of this Indenture as provided under Article 8.

At the request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release.

SECTION 10.07.        Contribution.  Each Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

ARTICLE 11

Satisfaction and Discharge

SECTION 11.01.        Satisfaction and Discharge.

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

(1)           either:

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

(B)           all Securities that have not been delivered to the Registrar for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Paying Agent as trust funds in trust solely for the benefit of the holders, cash in U.S. 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 Securities not delivered to the Registrar for cancellation for principal of, premium on, if any, or interest, if any, on, the Securities to the date of stated maturity or redemption;

(2)           in respect of Section 11.01(a)(1)(B), no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing

64

of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings);

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

(4)           the Company has delivered irrevocable instructions to the Paying Agent to apply the deposited money toward the payment of the Securities at stated maturity or on the redemption date, as the case may be.

The Company or the Trustee by notice to the other may designate additional or different addresses for subsequent notices or communications.

Any notice or communication mailed to a Securityholder shall be mailed to the Securityholder at the Securityholder’s address as it appears on the registration books of the Registrar and shall be sufficiently given if so mailed within the time prescribed.

Failure to mail a notice or communication to a Securityholder or any defect in it shall not affect its sufficiency with respect to other Securityholders.  If a notice or communication is mailed in the manner provided above, it is duly given, whether or not the addressee receives it.

SECTION 12.03.        Communication by Holders with Other Holders.  Securityholders may communicate pursuant to Trust Indenture Act § 312(b) with other Securityholders with respect to their rights under this Indenture or the Securities.  The Company, any Guarantor, the Trustee, the Paying Agent, the Registrar and anyone else shall have the protection of Trust Indenture Act § 312(c).

SECTION 12.04.        Certificate and Opinion as to Conditions Precedent.  Upon any request or application by the Company or any of the Guarantors to the Trustee or to the Paying Agent to take or refrain from taking any action under this Indenture, the Company or such Guarantor shall furnish to the Trustee or the Paying Agent, as applicable:

(1)           an Officers’ Certificate in form and substance reasonably satisfactory to the Trustee or Paying Agent, as applicable, stating that, in the opinion of the signers, all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with; and

(2)           an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee or the Paying Agent, as applicable, stating that, in the opinion of such counsel, all such conditions precedent have been complied with; provided, however, that such Opinion of Counsel shall not be required to be furnished in connection with the issuance of the Securities on the Issue Date.

SECTION 12.05.        Statements Required in Certificate or Opinion.  Each certificate or opinion with respect to compliance with a covenant or condition provided for in this Indenture shall include:

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

(4)           a statement as to whether or not, in the opinion of such individual, such covenant or condition has been complied with.

SECTION 12.06.        When Securities are Disregarded.  In determining whether the holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company

66

or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee or the Paying Agent shall be protected in conclusively relying on any such direction, waiver or consent, only Securities which a Responsible Officer of the Trustee or the Paying Agent, as the case may be, actually knows are so owned shall be so disregarded.  Also, subject to the foregoing, only Securities outstanding at the time shall be considered in any such determination.

SECTION 12.07.        Consent to Jurisdiction and Service of Process.  The Company and each of the Guarantors hereby appoints the principal office of Corporation Service Company in The City of New York which, on the date hereof, is located at 1180 Avenue of the Americas  Suite 210, New York, New York 10036, as the authorized agent thereof (the “Authorized Agent”) upon whom process may be served in any action, suit or proceeding arising out of or based on this Indenture or the Securities which may be instituted in the Supreme Court of the State of New York or the United States District Court for the Southern District of New York, in either case in The Borough of Manhattan, The City of New York, by the Holder of any Security, and to the fullest extent permitted by applicable law, the Company hereby waives any objection which it may now or hereafter have to the laying of venue of any such proceeding and expressly and irrevocably accepts and submits, for the benefit of the Holders from time to time of the Securities, to the nonexclusive jurisdiction of any such court in respect of any such action, suit or proceeding, for itself and with respect to its properties, revenues and assets.  Such appointment shall be irrevocable unless and until the appointment of a successor authorized agent for such purpose, and such successor’s acceptance of such appointment, shall have occurred.  The Company agrees to take any and all actions, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect as aforesaid.  Service of process upon the Authorized Agent with respect to any such action shall be deemed, in every respect, effective service of process upon the Company.  Notwithstanding the foregoing, any action against the Company arising out of or based on any Security may also be instituted by the Holder of such Security in any court in the jurisdiction of organization of the Company, and the Company expressly accepts the jurisdiction of any such court in any such action.  The Company shall require the Authorized Agent to agree in writing to accept the foregoing appointment as agent for service of process.

SECTION 12.08.        Waiver of Immunity.  To the extent that the Company or any of its properties, assets or revenues may have or may hereafter become entitled to, or have attributed to it, any right of immunity, on the grounds of sovereignty or otherwise, from any legal action, suit or proceeding, from the giving of any relief in any thereof, from set off or counterclaim, from the jurisdiction of any court, from service of process, from attachment upon or prior to judgment, from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any jurisdiction in which proceedings may at any time be commenced, with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Indenture or the Securities, the Company, to the maximum extent permitted by law, hereby irrevocably and unconditionally waives, and agrees not to plead or claim, any such immunity and consents to such relief and enforcement.

SECTION 12.09.        Rules by Trustee, Paying Agent and Registrar.  The Trustee may make reasonable rules for action by or a meeting of Securityholders.  The Registrar and the Paying Agent may make reasonable rules and set reasonable requirements for their functions.

SECTION 12.10.        Legal Holidays.  If a payment date is a Legal Holiday, payment shall be made on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period.  If a regular record date is a Legal Holiday, the record date shall not be affected.

SECTION 12.11.        Governing Law.  This Indenture and the Securities shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 12.12.        No Recourse Against Others.  No director, officer, employee, member, partner, incorporator or stockholder of the Company or any of its Subsidiaries, as such, will have any liability for any obligations of the Company or the Guarantors under the Securities, this Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation or the transactions contemplated thereby.  Each holder of Securities by accepting a Security waives and releases all such liability.  The waiver and release are part of

67

the consideration for issuance of the Securities.  The waiver may not be effective to waive liabilities under the federal securities laws.

SECTION 12.13.        Successors.  All agreements of the Company and each Guarantor in this Indenture and the Securities shall bind their successors.  All agreements of the Trustee, the Paying Agent, the Authenticating Agent and the Registrar in this Indenture shall bind its successors.

SECTION 12.14.        Severability.  In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 12.15.        Multiple Originals.  The parties may sign any number of copies of this Indenture.  Each signed copy shall be an original, but all of them together represent the same agreement.  One signed copy is enough to prove this Indenture.  The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes.  Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.

SECTION 12.16.        Table of Contents; Headings.  The table of contents, cross-reference sheet and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions hereof.

SECTION 12.17.        WAIVER OF JURY TRIAL.  THE COMPANY, THE GUARANTORS AND THE TRUSTEE, PAYING AGENT, REGISTRAR AND AUTHENTICATING AGENT HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE SECURITIES OR THE TRANSACTIONS CONTEMPLATED HEREBY.

SECTION 12.18.        U.S.A. Patriot Act.  The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the Trustee and Paying Agent, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Trustee and Paying Agent.  The parties to this Indenture agree that they will provide the Trustee and Paying Agent with such information as it may request in order for the Trustee and Paying Agent to satisfy the requirements of the U.S.A. Patriot Act.
