Definitions and Incorporation by Reference

SECTION 1.1. Definitions.

“Acquired Indebtedness” means Indebtedness (i) of a Person or any of its Subsidiaries existing at the time such Person becomes a Restricted Subsidiary or (ii) assumed in connection with the acquisition of assets from such Person, in each case whether or not Incurred by such Person in connection with, or in anticipation or contemplation of, such Person becoming a Restricted Subsidiary or such acquisition. Acquired Indebtedness shall be deemed to have been Incurred, with respect to clause (i) of the preceding sentence, on the date such Person becomes a Restricted Subsidiary and, with respect to clause (ii) of the preceding sentence, on the date of consummation of such acquisition of assets.

“Additional Assets” means:

(1)

any property or assets (other than Indebtedness and Capital Stock) to be used by the Company or a Restricted Subsidiary in the Oil and Gas Business;

(2)

capital expenditures by the Company or a Restricted Subsidiary in the Oil and Gas Business;

(3)

the Capital Stock of a Person that becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by the Company or a Restricted Subsidiary; or

(4)

Capital Stock constituting a minority interest in any Person that at such time is a Restricted Subsidiary;

provided, however, that, in the case of clauses (3) and (4), such Restricted Subsidiary is primarily engaged in the Oil and Gas Business.

“Adjusted Consolidated Net Tangible Assets” means (without duplication), as of the date of determination, the remainder of:

(1)

the sum of:

(a)

discounted future net revenues from proved oil and gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with Commission guidelines before any provincial, territorial, state, Federal or foreign income taxes, as estimated by the Company in a reserve report prepared as of the end of the Company’s most recently completed fiscal year for which audited financial statements are available, as increased by, as of the date of determination, the estimated discounted future net revenues from

(i)

estimated proved oil and gas reserves acquired since such year end, which reserves were not reflected in such year end reserve report, and

(ii)

estimated oil and gas reserves attributable to upward revisions of estimates of proved oil and gas reserves since such year end due to exploration, development or exploitation activities, in each case calculated in accordance with Commission guidelines (utilizing the prices for the fiscal quarter ending prior to the date of determination),

and decreased by, as of the date of determination, the estimated discounted future net revenues from

(iii)

estimated proved oil and gas reserves produced or disposed of since such year end, and

(iv)

estimated oil and gas reserves attributable to downward revisions of estimates of proved oil and 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 and substantially in accordance with Commission guidelines (utilizing the prices for the fiscal quarter ending prior to the date of determination), in each case as estimated by the Company’s petroleum engineers or any independent petroleum engineers engaged by the Company for that purpose;

(b)

the capitalized costs that are attributable to oil and gas properties of the Company and its Restricted Subsidiaries to which no proved oil and gas reserves are attributable, based on the Company’s books and records as of a date no earlier than the date of the Company’s latest available annual or quarterly financial statements;

(c)

the Net Working Capital on a date no earlier than the date of the Company’s latest annual or quarterly financial statements; and

(d)

the greater of

(i)

the net book value of other tangible assets of the Company and its Restricted Subsidiaries, as of a date no earlier than the date of the Company’s latest annual or quarterly financial statement, and

(ii)

the appraised value, as estimated by independent appraisers, of other tangible assets of the Company and its Restricted Subsidiaries, as of a date no earlier than the date of the Company’s latest audited financial statements; minus

(2)

the sum of:

(a)

Minority Interests;

(b)

any net gas balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest audited financial statements;

(c)

to the extent included in (1)(a) above, the discounted future net revenues, calculated in accordance with Commission guidelines (utilizing the prices utilized in the Company’s year end reserve report), attributable to reserves which are required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with respect to Volumetric Production Payments (determined, if applicable, using the schedules specified with respect thereto); and

(d)

the discounted future net revenues, calculated in accordance with Commission guidelines, attributable to reserves subject to Dollar-Denominated Production Payments which, based on the estimates of production and price assumptions included in determining the discounted future net revenues specified in (1)(a) above, would be necessary to fully satisfy the payment obligations of the Company and its Subsidiaries with respect to Dollar-Denominated Production Payments (determined, if applicable, using the schedules specified with respect thereto).

If the Company changes its method of accounting from the successful efforts method of accounting to the full cost or a similar method, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if the Company were still using the successful efforts method of accounting.

“Consolidated Coverage Ratio” means as of any date of determination, with respect to any Person, the ratio of (x) the aggregate amount of Consolidated EBITDAX of such Person for the period of the most recent four consecutive fiscal quarters ending prior to the date of such determination for which financial statements are in existence to (y) Consolidated Interest Expense for such four fiscal quarters, provided, however, that:

(1)

if the Company or any Restricted Subsidiary:

(a)

has Incurred any Indebtedness since the beginning of such period that remains outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving effect on a pro forma basis to such Indebtedness as if such Indebtedness had been Incurred on the first day of such period (except that in making such computation, the amount of Indebtedness under any revolving credit facility

outstanding on the date of such calculation will be deemed to be (i) the average daily balance of such Indebtedness during such four fiscal quarters or such shorter period for which such facility was outstanding or (ii) if such facility was created after the end of such four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of creation of such facility to the date of such calculation) and the discharge of any other Indebtedness repaid, repurchased, defeased or otherwise discharged with the proceeds of such new Indebtedness as if such discharge had occurred on the first day of such period; or

(b)

has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of the period that is no longer outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio involves a discharge of Indebtedness (in each case other than Indebtedness Incurred under any revolving credit facility unless such Indebtedness has been permanently repaid and the related commitment terminated), Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving effect on a pro forma basis to such discharge of such Indebtedness, including with the proceeds of such new Indebtedness, as if such discharge had occurred on the first day of such period;

(2)

if since the beginning of such period the Company or any Restricted Subsidiary will have made any Asset Disposition or disposed of any company, division, operating unit, segment, business, group of related assets or line of business or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is such an Asset Disposition:

(a)

the Consolidated EBITDAX for such period will be reduced by an amount equal to the Consolidated EBITDAX (if positive) directly attributable to the assets which are the subject of such Asset Disposition for such period or increased by an amount equal to the Consolidated EBITDAX (if negative) directly attributable thereto for such period; and

(b)

Consolidated Interest Expense for such period will be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to

the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale);

(3)

if since the beginning of such period the Company or any Restricted Subsidiary (by merger or otherwise) will have made an Investment in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary or is merged with or into the Company) or an acquisition of assets, including any acquisition of assets occurring in connection with a transaction causing a calculation to be made hereunder, which constitutes all or substantially all of a company, division, operating unit, segment, business, group of related assets or line of business, Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition had occurred on the first day of such period; and

(4)

if since the beginning of such period any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) will have Incurred any Indebtedness or discharged any Indebtedness, made any Asset Disposition or any Investment or acquisition of assets that would have required an adjustment pursuant to clause (2) or (3) above if made by the Company or a Restricted Subsidiary during such period, Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto as if such Asset Disposition or Investment or acquisition of assets had occurred on the first day of such period.

For purposes of this definition, whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations will be determined in good faith by a responsible financial or accounting officer of the Company (including pro forma expense and cost reductions calculated on a basis consistent with Regulation S-X under the Securities Act).

If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on such Indebtedness will be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement has a remaining term in excess of 12 months). If any Indebtedness that is being given pro forma effect bears an interest rate at the option of the Company, the interest rate shall be calculated by applying such optional rate chosen by the Company.

“Consolidated EBITDAX” for any period means, without duplication, the Consolidated Net Income for such period, plus the following to the extent deducted in calculating such Consolidated Net Income:

(1)

Consolidated Interest Expense;

(2)

Consolidated Income Taxes;

(3)

consolidated depreciation expense;

(4)

consolidated amortization expense or impairment charges recorded in connection with the application of Statement of Financial Accounting Standard No. 142 “Goodwill and Other Intangibles”;

(5)

other non-cash charges reducing Consolidated Net Income (excluding any such non-cash charge to the extent it represents an accrual of or reserve for cash charges in any future period or amortization of a prepaid cash expense that was paid in a prior period not included in the calculation); and

THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF, AGREES ON ITS OWN BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HAS PURCHASED SECURITIES, TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE “RESALE RESTRICTION TERMINATION DATE”) THAT IS FORTY DAYS AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH THE COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR OF SUCH SECURITY), ONLY (A) TO THE COMPANY, (B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT, (E) TO AN INSTITUTIONAL ACCREDITED INVESTOR WITHIN THE MEANING OF RULE 501(a)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT THAT IS AN INSTITUTIONAL ACCREDITED INVESTOR ACQUIRING THE SECURITY FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF SUCH AN INSTITUTIONAL ACCREDITED INVESTOR, IN EACH CASE IN A MINIMUM PRINCIPAL AMOUNT OF THE SECURITIES OF $250,000, FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TO OR FOR OFFER OR SALE IN CONNECTION WITH ANY DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, OR (F) PURSUANT TO ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S AND THE TRUSTEE’S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSES (D), (E) AND (F) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM.

THIS SECURITY IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT.”

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THIS INDENTURE REFERRED TO ON THE REVERSE HEREOF.”

(e) Book-Entry Provisions.

(i) This Section 2.1(e) shall apply only to Global Securities deposited with the Trustee, as custodian for DTC.

(ii) Each Global Security initially shall (x) be registered in the name of DTC for such Global Security or the nominee of DTC, (y) be delivered to the Trustee as custodian for DTC and (z) bear legends as set forth in Section 2.1(d).

(iii) Members of, or participants in, DTC (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by DTC or by the Trustee as the custodian of DTC or under such Global Security, and DTC may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the operation of customary practices of DTC governing the exercise of the rights of a Holder of a beneficial interest in any Global Security.

(iv) In connection with any transfer of a portion of the beneficial interest in a Global Security pursuant to subsection (f) of this Section 2.1 to beneficial owners who are required to hold Definitive Securities, the Securities Custodian shall reflect on its books and

records the date and a decrease in the principal amount of such Global Security in an amount equal to the principal amount of the beneficial interest in the Global Security to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Definitive Securities of like tenor and amount.

(v) In connection with the transfer of an entire Global Security to beneficial owners pursuant to subsection (f) of this Section 2.1, such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Definitive Securities of authorized denominations.

(vi) The registered Holder of a Global Security may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities.

(f) Definitive Securities. (i) Except as provided below, owners of beneficial interests in Global Securities will not be entitled to receive Definitive Securities. If required to do so pursuant to any applicable law or regulation, beneficial owners may obtain Definitive Securities in exchange for their beneficial interests in a Global Security upon written request in accordance with DTC’s and the Registrar’s procedures. In addition, Definitive Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Security if (a) DTC notifies the Company that it is unwilling or unable to continue as depositary for such Global Security or DTC ceases to be a clearing agency registered under the Exchange Act, at a time when DTC is required to be so registered in order to act as depositary, and in each case a successor depositary is not appointed by the Company within 90 days of such notice or, (b) the Company executes and delivers to the Trustee and Registrar an Officers’ Certificate stating that such Global Security shall be so exchangeable or (c) an Event of Default has occurred and is continuing and the Registrar has received a request from DTC.

(ii) Any Definitive Security delivered in exchange for an interest in a Global Security pursuant to Section 2.1(e)(iv) or (v) shall, except as otherwise provided by Section 2.6(c), bear the applicable legend regarding transfer restrictions applicable to the Definitive Security set forth in Section 2.1(d).

(iii) In connection with the exchange of a portion of a Definitive Security for a beneficial interest in a Global Security, the Trustee shall cancel such Definitive Security, and the Company shall execute, and the Trustee shall authenticate and deliver, to the transferring Holder a new Definitive Security representing the principal amount not so transferred.

SECTION 2.2. 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 Trustee authenticates the Security, the Security shall be valid nevertheless, after giving effect to any exchange of Initial Securities for Exchange Securities.

A Security shall not be valid until an authorized signatory of the Trustee manually authenticates the Security. The signature of the Trustee on a Security shall be conclusive evidence that such Security has been duly and validly authenticated and issued under this Indenture. A Security shall be dated the date of its authentication.

At any time and from time to time after the execution and delivery of this Indenture, the Trustee shall authenticate and make available for delivery: (1) Initial Securities for original issue on the Issue Date in an aggregate principal amount of $150,000,000, (2) Additional Securities for original issue and (3) Exchange Securities for issue only in an Exchange Offer pursuant to the Registration Rights Agreement, and only in exchange for Initial Securities or Additional Securities of an equal principal amount, in each case upon a written order of the Company signed by two Officers or by an Officer and either an Assistant Treasurer or an Assistant Secretary of the Company (the “Company Order”). Such Company 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 whether the Securities are to be Initial Securities, Additional Securities or Exchange Securities.

The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating Agent.

In case the Company or any Subsidiary Guarantor, pursuant to Article IV, shall be consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any Person, and the Successor Company resulting from such consolidation, or surviving such merger, or into which the Company shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed an indenture supplemental hereto with the Trustee pursuant to Article IV, any of the Securities authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to time, at the request of the Successor Company, be exchanged for other Securities executed in the name of the Successor Company with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Securities surrendered for such exchange and of like principal amount; and the Trustee, upon Company Order of the Successor Company, shall authenticate and deliver Securities as specified in such order for the purpose of such exchange. If Securities shall at any time be authenticated and delivered in any new name of a Successor Company pursuant to this Section 2.2 in exchange or substitution for or upon registration of transfer of any Securities, such Successor Company, at the option of the Holders but without expense to them, shall provide for the exchange of all Securities at the time outstanding for Securities authenticated and delivered in such new name.

SECTION 2.3. Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Company shall cause each of the Registrar and the Paying Agent to maintain an office or agency in the Borough of Manhattan, The City of New York. The

Registrar shall keep a register of the Securities and of their transfer and exchange (the “Note 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.

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of each such 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 7.7. The Company or any of its Restricted Subsidiaries may act as Paying Agent, Registrar, co-registrar or transfer agent.

The Company initially appoints the Trustee as Registrar and Paying Agent for the Securities.

SECTION 2.4. Paying Agent to Hold Money in Trust. By no later than 10:00 a.m. (New York City time) on the date on which any principal of or interest on any Security is due and payable, the Company shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal or interest when due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by such Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee in writing of any default by any of the Company or any Subsidiary Guarantor in making any such payment. If the Company or a Subsidiary 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 (other than the Trustee) to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section 2.4, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect to the Company, the Trustee shall serve as Paying Agent for the Securities.

SECTION 2.5. Securityholder Lists. The Trustee 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, or to the extent otherwise required under the TIA, the Company shall furnish to the Trustee, in writing at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders.

SECTION 2.6. Transfer and Exchange.

(a) The following provisions shall apply with respect to any proposed transfer of a Rule 144A Note or an Institutional Accredited Investor Note prior to the date which is two years after the later of the date of its original issue and the last date on which the Company or any affiliate of the Company was the owner of such Securities (or any predecessor thereto) (the “Resale Restriction Termination Date”):

(i) a transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest therein to a QIB shall be made upon the representation of the transferee in the form as set forth on the reverse of the Security that it is purchasing for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a “qualified institutional buyer” within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A;

(ii) a transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest therein to an IAI shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth in Exhibit C from the proposed transferee and, if requested by the Company or the Trustee, the delivery of an opinion of counsel stating that such transaction is exempt from registration under the Federal securities laws, certification and/or other information satisfactory to each of them; and

(iii) a transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest therein to a Non-U.S. Person shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth in Exhibit D from the proposed transferee and, if requested by the Company or the Trustee, the delivery of an opinion of counsel stating that such transaction is exempt from registration under the Federal securities laws, certification and/or other information satisfactory to each of them.

(b) The following provisions shall apply with respect to any proposed transfer of a Regulation S Note prior to the expiration of the Restricted Period:

(i) a transfer of a Regulation S Note or a beneficial interest therein to a QIB shall be made upon the representation of the transferee, in the form of assignment on the reverse of the certificate, that it is purchasing the Security for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a “qualified institutional buyer” within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A;

(ii) a transfer of a Regulation S Note or a beneficial interest therein to an IAI shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth in Exhibit C from the proposed transferee and, if requested by the Company or the Trustee, the delivery of an opinion of counsel stating that such transaction is exempt from registration under the Federal securities laws, certification and/or other information satisfactory to each of them; and

(iii) a transfer of a Regulation S Note or a beneficial interest therein to a Non-U.S. Person shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth in Exhibit D hereof from the proposed transferee and, if requested by the Company or the Trustee, receipt by the Trustee or its agent of an opinion of counsel stating that such transaction is exempt from registration under the Federal securities laws, certification and/or other information satisfactory to each of them.

After the expiration of the Restricted Period, interests in the Regulation S Note may be transferred without requiring the certification set forth in Exhibit C, Exhibit D or any additional certification.

(c) Restricted Securities Legend. Upon the transfer, exchange or replacement of Securities not bearing a Restricted Securities Legend, the Registrar shall deliver Securities that do not bear a Restricted Securities Legend unless such transferee is an affiliate (as defined in Rule 144A) of the Company. Upon the registration of transfer, exchange or replacement of Securities bearing a Restricted Securities Legend, the Registrar shall deliver only Securities that bear a Restricted Securities Legend unless there is delivered to the Registrar an Opinion of Counsel to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

(d) The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.1 or this Section 2.6. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable prior written notice to the Registrar.

(e) Obligations with Respect to Transfers and Exchanges of Securities.

(i) To permit registrations of transfers and exchanges, the Company shall, subject to the other terms and conditions of this Article II, execute and the Trustee shall authenticate Definitive Securities and Global Securities at the Registrar’s or co-registrar’s request.

(ii) No service charge shall be made to a Holder for any registration of transfer or exchange, but the Company or the Trustee may require payment by a Holder of a sum sufficient to cover any transfer tax, assessments, or similar governmental taxes and fees payable in connection therewith (other than any such transfer taxes, assessments or similar governmental taxes and fees payable upon exchange or transfer pursuant to Sections 3.8, 3.10 or 9.5).

(iii) The Registrar or co-registrar shall not be required to register the transfer of or exchange of any Security for a period beginning (1) 15 days before the selection of Securities to be repurchased or redeemed and ending at the close of business on the day of such selection (except, in the case of Securities to be redeemed in part, the portion of the Security not to be redeemed) or (2) 15 days before an interest payment date and ending on such interest payment date.

(iv) Prior to the due presentation for registration of transfer of any Security, the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar may deem

and treat the person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar shall be affected by notice to the contrary.

(v) Any Definitive Security delivered in exchange for an interest in a Global Security pursuant to Section 2.1(e) shall, except as otherwise provided by Section 2.6(c), bear the applicable legend regarding transfer restrictions applicable to the Definitive Security set forth in Section 2.1(d).

(vi) All Securities issued upon any registration of transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Securities surrendered upon such registration of transfer or exchange.

(f) No Obligation of the Trustee.

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

(ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among DTC participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

SECTION 2.7. Mutilated, Destroyed, Lost or Stolen 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 the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Securityholder (a) satisfies the Company or the Trustee

within a reasonable time after such Securityholder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Company or Trustee prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Subsidiary Guarantors, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced, and, in the absence of notice to the Company, the Subsidiary Guarantors or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute and upon Company Order the Trustee shall authenticate and make available for delivery, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section 2.7, the Company 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 Trustee) in connection therewith.

Every new Security issued pursuant to this Section 2.7 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, any Subsidiary Guarantor (if applicable) and any other obligor upon the Securities, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

The provisions of this Section 2.7 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 2.8. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.8 as not outstanding. A Security shall be deemed to be outstanding in the event the Company or an Affiliate of the Company holds the Security, provided, however, that (i) for purposes of determining which are outstanding for consent or voting purposes hereunder, the provisions of Section 11.6 shall apply and (ii) in determining whether the Trustee shall be protected in making a determination whether the Holders of the requisite principal amount of outstanding Securities are present at a meeting of Holders of Securities for quorum purposes or have consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such quorum, consent or vote, only Securities which a Trust Officer of the

Trustee actually knows to be held by the Company or an Affiliate of the Company shall not be considered outstanding.

If a Security is replaced pursuant to Section 2.7, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser.

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, and the Paying Agent is not prohibited from paying such money to the Securityholders on that date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.9. Temporary Securities. In the event that Definitive Securities are to be issued under the terms of this Indenture, until such Definitive Securities are ready for delivery, the Company may prepare and the Trustee shall 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 Trustee shall authenticate Definitive Securities. After the preparation of Definitive Securities, the temporary Securities shall be exchangeable for Definitive Securities upon surrender of the temporary Securities at any office or agency maintained by the Company for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute, and the Trustee shall authenticate and make available for delivery in exchange therefor, one or more Definitive Securities representing an equal principal amount of Securities. Until so exchanged, the Holder of temporary Securities shall in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Securities.

SECTION 2.10. Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and destroy such Securities in accordance with its internal policies and, upon the Company’s written request, deliver a certificate (a “Certificate of Destruction”) describing such Securities disposed (subject to the record retention requirements of the Exchange Act). The Company may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange.

SECTION 2.11. Payment of Interest; Defaulted Interest. Interest on any Security which is payable, and is punctually paid or duly provided for, on any interest payment date shall be paid to the Person in whose name such Security (or one or more predecessor Securities) is registered at the close of business on the regular record date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 2.3.

Any interest on any Security which is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 days shall forthwith cease to be payable to the Holder on the regular record date by virtue of having been such Holder, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne by the Securities (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Company, at its election in each case, as provided in clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date (not less than 30 days after such notice) of the proposed payment (the “Special Interest Payment Date”), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a record date (the “Special Record Date”) for the payment of such Defaulted Interest, which date shall be not more than 15 days and not less than 10 days prior to the Special Interest Payment Date and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date, and in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 11.2, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

(b) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section 2.11, each Security delivered under this Indenture upon registration of, transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 2.12. Computation of Interest. Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 2.13. CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” 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 CUSIP numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP numbers.

ARTICLE III

Covenants

SECTION 3.1. 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 Trustee or the Paying Agent holds in accordance with this Indenture immediately available funds sufficient to pay all principal and interest then due.

The Company shall pay interest on overdue principal at the rate specified therefor in the Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

Notwithstanding anything to the contrary contained in this Indenture, the Company may, to the extent it is required to do so by law, deduct or withhold income or other similar taxes imposed by the United States of America from principal or interest payments hereunder.

SECTION 3.2. Commission Reports. Notwithstanding that the Company may not continue to be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, to the extent permitted by the Exchange Act, the Company will file with the Commission, and make available to the Trustee and the registered Holders of the Securities, the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may by rules and regulations prescribe) that are specified in Sections 13 and 15(d) of the Exchange Act within the time periods specified therein. In the event that the Company is not permitted to file such reports, documents and information with the Commission pursuant to the Exchange Act, the Company will nevertheless make available such Exchange Act information to the Trustee and the Holders of the Securities 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.

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

paragraph shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes to the financial statements and in Management’s Discussion and Analysis of Results of Operations and Financial Condition, of the financial condition and results of operations of the Company and its Restricted Subsidiaries.

SECTION 3.3. Limitation on Indebtedness. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, Incur any Indebtedness (including Acquired Indebtedness); provided, however, that the Company and the Subsidiary Guarantors may Incur Indebtedness if on the date thereof:

(1)

the Consolidated Coverage Ratio for the Company and its Restricted Subsidiaries is at least (a) 2.50 to 1.00; and

(2)

no Default or Event of Default will have occurred or be continuing or would occur as a consequence of Incurring the Indebtedness or transactions relating to such Incurrence.

The first paragraph of this Section 3.3 will not prohibit the Incurrence of the following Indebtedness:

(1)

Indebtedness of the Company Incurred pursuant to a Credit Facility in an aggregate amount up to the greater of (a) $125.0 million or (b) so long as the Consolidated Coverage Ratio for the Company and its Restricted Subsidiaries is at least 2.00 to 1.00 after giving effect to any such Incurrence, 20.0% of Adjusted Consolidated Net Tangible Assets determined as of the date of the Incurrence of such Indebtedness;

(2)

Guarantees by the Subsidiary Guarantors of Indebtedness Incurred in accordance with the provisions of this Indenture; provided that in the event such Indebtedness that is being Guaranteed is a Subordinated Obligation or a Guarantor Subordinated Obligation, then the related Guarantee shall be subordinated in right of payment to the Subsidiary Guarantee;

(3)

Indebtedness of the Company owing to and held by any Wholly-Owned Subsidiary or Indebtedness of a Restricted Subsidiary owing to and held by the Company or any Wholly-Owned Subsidiary, provided, however;

(a)

if the Company is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to the prior payment in full in cash of all obligations with respect to the Securities;

(b)

if a Subsidiary Guarantor is the obligor on such Indebtedness and the Company or a Subsidiary Guarantor is not the obligee, such Indebtedness is subordinated in right of payment to the Subsidiary Guarantees of such Subsidiary Guarantor; and


(c)	(i)	any subsequent issuance or transfer of Capital Stock or any other event which results in any such Indebtedness being beneficially held by a Person other than the Company or a Wholly-Owned Subsidiary of the Company; and

	(ii)	any sale or other transfer of any such Indebtedness to a Person other than the Company or a Wholly-Owned Subsidiary of the Company,

shall be deemed, in each case, to constitute an Incurrence of such Indebtedness by the Company or such Subsidiary, as the case may be;

(3)

Indebtedness represented by (a) the Securities issued on the Issue Date, the Subsidiary Guarantees and the Exchange Securities and Exchange Guarantees issued in an Exchange Offer, (b) any Indebtedness (other than the Indebtedness described in clauses (1), (2), (3), (6), (8), (9) and (10)) outstanding on the Issue Date and (c) any Refinancing Indebtedness Incurred in respect of any Indebtedness described in this clause (4) or clause (5) or Incurred pursuant to the first paragraph of this Section 3.3;

(4)

Indebtedness of a Subsidiary Guarantor Incurred and outstanding on the date on which such Subsidiary Guarantor was acquired by the Company (other than Indebtedness Incurred (a) to provide all or any portion of the funds utilized to consummate the transaction or series of related transactions pursuant to which such Subsidiary Guarantor became a Restricted Subsidiary or was otherwise acquired by the Company or (b) otherwise in connection with, or in contemplation of, such acquisition); provided, however, that at the time such Restricted Subsidiary is acquired by the Company, the Company would have been able to Incur $1.00 of additional Indebtedness pursuant to the first paragraph of this Section 3.3 giving effect to the Incurrence of such Indebtedness pursuant to this clause (5);

(5)

Indebtedness under Currency Agreements, Commodity Agreements and Interest Rate Agreements; provided, that such Agreements are entered into for bona fide hedging purposes of the Company or its Restricted Subsidiaries (as determined in good faith by the Board of Directors or senior management of the Company) and, in the case of Currency Agreements or Commodity Agreements, such Currency Agreements or Commodity Agreements are related to business transactions of the Company or its Restricted Subsidiaries entered into in the ordinary course of business and, in the case of Interest Rate Agreements, such Interest Rate Agreements substantially correspond in terms of notional amount, duration and interest rates, as applicable, to Indebtedness of the Company or its Restricted Subsidiaries Incurred without violation of this Indenture;

(6)

the Incurrence by the Company or any of its Subsidiary Guarantors of Indebtedness represented by Capitalized Lease Obligations, mortgage financings or purchase money obligations with respect to assets other than Capital Stock or other Investments, in each case Incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvements of property used in the business of the Company or such Subsidiary Guarantor, in an aggregate principal amount not to exceed $10.0 million at any time outstanding;

(7)

Indebtedness Incurred in respect of workers’ compensation claims, self-insurance obligations, bid, reimbursement, performance, surety and similar bonds and completion guarantees provided by the Company or a Restricted Subsidiary in the ordinary course of business, including supporting Guarantees and letters of credit (in each case other than for an obligation for money borrowed);

(8)

Indebtedness arising from agreements of the Company or a Restricted Subsidiary providing for indemnification, adjustment of purchase price or similar obligations, in each case, Incurred or assumed in connection with the disposition of any business, assets or Capital Stock of a Restricted Subsidiary, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by the Company and its Restricted Subsidiaries in connection with such disposition;

(9)

Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business, provided, however, that such Indebtedness is extinguished within five business days of Incurrence; and

(10)

in addition to the items referred to in clauses (1) through (10) above, Indebtedness of the Company and its Subsidiary Guarantors in an aggregate outstanding principal amount which, when taken together with the principal amount of all other Indebtedness Incurred pursuant to this clause (11) and then outstanding, will not exceed $20.0 million at any time outstanding.

The Company will not Incur any Indebtedness under the preceding paragraph if the proceeds thereof are used, directly or indirectly, to refinance any Subordinated Obligations of the Company unless such Indebtedness will be subordinated to the Securities to at least the same extent as such Subordinated Obligations.

No Subsidiary Guarantor will Incur any indebtedness if the proceeds thereof are used, directly or indirectly, to refinance any Guarantor Subordinated Obligations of such Subsidiary Guarantor unless such Indebtedness will be subordinated to the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee to at least the same extent as such

Guarantor Subordinated Obligations. No Restricted Subsidiary may Incur any Indebtedness if the proceeds are used to refinance Indebtedness of the Company.

For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness Incurred pursuant to and in compliance with, this Section 3.3:

(1)

in the event that Indebtedness meets the criteria of more than one of the types of Indebtedness described in the first and second paragraphs of this Section 3.3, the Company, in its sole discretion, will classify and may reclassify such item of Indebtedness and only be required to include the amount and type of such Indebtedness in one of such clauses;

(2)

all Indebtedness outstanding on the date of this Indenture under the Senior Secured Credit Agreement shall be deemed initially Incurred on the Issue Date under clause (1) of the second paragraph of this Section 3.3 and not clause (4) of the second paragraph of this Section 3.3;

(3)

Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included;

(4)

if obligations in respect of letters of credit are Incurred pursuant to a Credit Facility and are being treated as Incurred pursuant to clause (1) of the second paragraph above and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included;

(5)

the principal amount of any Disqualified Stock of the Company or a Restricted Subsidiary, or Preferred Stock of a Restricted Subsidiary that is not a Subsidiary Guarantor, will be equal to the greater of the maximum mandatory redemption or repurchase price (not including, in either case, any redemption or repurchase premium) or the liquidation preference thereof;

(6)

Indebtedness permitted by this Section 3.3 need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 3.3 permitting such Indebtedness; and

(7)

the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

Accrual of interest, accrual of dividends, the accretion of accreted value, the payment of interest in the form of additional Indebtedness and the payment of dividends in the form of additional shares of Preferred Stock or Disqualified Stock will not be deemed to be an Incurrence of Indebtedness for purposes of this Section 3.3. The amount of any Indebtedness outstanding as of any date shall be (i) the accreted value thereof in the case of any Indebtedness

issued with original issue discount and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past due, in the case of any other Indebtedness.

In addition, the Company will not permit any of its Unrestricted Subsidiaries to Incur any Indebtedness or issue any shares of Disqualified Stock, other than Non-Recourse Debt. If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall 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 this Section 3.3, the Company shall be in Default of this Section 3.3).

For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 3.3, the maximum amount of Indebtedness that the Company may Incur pursuant to this Section 3.3 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

SECTION 3.4. Limitation on Restricted Payments. The Company shall not, and shall not permit any of its Restricted Subsidiaries, directly or indirectly, to:

(1)

declare or pay any dividend or make any distribution on or in respect of its Capital Stock (including any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) except:

(a)

dividends or distributions payable in Capital Stock of the Company (other than Disqualified Stock) or in options, warrants or other rights to purchase such Capital Stock of the Company; and

(b)

dividends or distributions payable to the Company or a Restricted Subsidiary (and if such Restricted Subsidiary is not a Wholly-Owned Subsidiary, to its other holders of common Capital Stock on a pro rata basis);

(2)

purchase, redeem, retire or otherwise acquire for value any Capital Stock of the Company or any direct or indirect parent of the Company held by Persons other than the Company or a Restricted Subsidiary (other than in exchange for Capital Stock of the Company (other than Disqualified Stock));

(3)

purchase, repurchase, redeem, defease or otherwise acquire or retire for value, prior to scheduled maturity, scheduled repayment or scheduled sinking fund payment, any Subordinated Obligations or Guarantor Subordinated Obligations (other than the purchase, repurchase, redemption, defeasance or other acquisition or retirement of Subordinated Obligations or Guarantor Subordinated Obligations purchased in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of purchase, repurchase, redemption, defeasance or other acquisition or retirement); or

(4)

make any Restricted Investment in any Person;

(any such dividend, distribution, purchase, redemption, repurchase, defeasance, other acquisition, retirement or Restricted Investment referred to in clauses (1) through (4) shall be referred to herein as a “Restricted Payment”), if at the time the Company or such Restricted Subsidiary makes such Restricted Payment:

(a)

a Default shall have occurred and be continuing (or would result therefrom); or

(b)

the Company is not able to Incur an additional $1.00 of Indebtedness pursuant to the first paragraph of Section 3.3 after giving effect, on a pro forma basis, to such Restricted Payment; or

(c)

the aggregate amount of such Restricted Payment and all other Restricted Payments declared or made subsequent to the Issue Date would exceed the sum of:

(i)

50% of Consolidated Net Income for the period (treated as one accounting period) from the beginning of the first fiscal quarter commencing after the Issue Date to the end of the most recent fiscal quarter ending prior to the date of such Restricted Payment for which financial statements are in existence (or, in case such Consolidated Net Income is a deficit, minus 100% of such deficit);

(ii)

100% of the aggregate Net Cash Proceeds received by the Company from the issue or sale of its Capital Stock (other than Disqualified Stock) or other capital contributions subsequent to the Issue Date (other than Net Cash Proceeds received from an issuance or sale of such Capital Stock to a Subsidiary of the Company or an employee stock

ownership plan, option plan or similar trust to the extent such sale to an employee stock ownership plan, option plan or similar trust is financed by loans from or Guaranteed by the Company or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination);

(iii)

the amount by which Indebtedness of the Company or its Restricted Subsidiaries is reduced on the Company’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) subsequent to the Issue Date of any Indebtedness of the Company or its Restricted Subsidiaries convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the Company (less the amount of any cash, or the fair market value of any other property, distributed by the Company upon such conversion or exchange); and

(iv)

the amount equal to the net reduction in Restricted Investments made by the Company or any of its Restricted Subsidiaries in any Person resulting from:

(A)

repurchases or redemptions of such Restricted Investments by such Person, proceeds realized upon the sale of such Restricted Investment to an unaffiliated purchaser, repayments of loans or advances or other transfers of assets (including by way of dividend or distribution) by such Person to the Company or any Restricted Subsidiary; or

(B)

the redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each case as provided in the definition of “Investment”) not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary,

which amount in each case under this clause (iv) was included in the calculation of the amount of Restricted Payments; provided, however, that no amount will be included under this clause (iv) to the extent it is already included in Consolidated Net Income.

The provisions of the preceding paragraph will not prohibit:

(1)

any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Capital Stock, Disqualified Stock or Subordinated Obligations of the Company or Guarantor Subordinated Obligations of any Subsidiary Guarantor made by exchange for, or out of the proceeds of the substantially concurrent sale of, Capital Stock of the Company (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary or an employee stock ownership plan or similar trust to the extent such sale to an employee stock ownership plan or similar trust is financed by loans from or Guaranteed by the Company or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination); provided, however, that (a) such purchase, repurchase, redemption, defeasance, acquisition or retirement will be excluded in subsequent calculations of the amount of Restricted Payments and (b) the Net Cash Proceeds from such sale of Capital Stock will be excluded from clause (c)(ii) of the preceding paragraph;

(2)

any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Subordinated Obligations of the Company or Guarantor Subordinated Obligations of any Subsidiary Guarantor or of any of its Restricted Subsidiaries made by exchange for, or out of the proceeds of the substantially concurrent sale of, Subordinated Obligations of the Company or any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Guarantor Subordinated Obligations made by exchange for or out of the proceeds of the substantially concurrent sale of Guarantor Subordinated Obligations that, in each case, is permitted to be Incurred pursuant to Section 3.3 and that in each case constitutes Refinancing Indebtedness; provided, however, that such purchase, repurchase, redemption, defeasance, acquisition or retirement will be excluded in subsequent calculations of the amount of Restricted Payments;

(3)

any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Disqualified Stock of the Company or a Restricted Subsidiary made by exchange for or out of the proceeds of the substantially concurrent sale of Disqualified Stock of the Company or such Restricted Subsidiary, as the case may be, that, in each case, is permitted to be Incurred pursuant to Section 3.3 and that in each case constitutes Refinancing Indebtedness; provided, however, that such purchase, repurchase, redemption, defeasance, acquisition or retirement will be excluded in subsequent calculations of the amount of Restricted Payments;

(4)

so long as no Default or Event of Default has occurred and is continuing, any purchase or redemption of Subordinated Obligations or Guarantor Subordinated Obligations of a Subsidiary Guarantor from Net Available Cash to the extent permitted under Section 3.8; provided, however, that such purchase or redemption will be excluded in subsequent calculations of the amount of Restricted Payments;

(5)

dividends paid within 60 days after the date of declaration if at such date of declaration such dividend would have complied with this provision; provided, however, that such dividends will be included in subsequent calculations of the amount of Restricted Payments;

(6)

so long as no Default or Event of Default has occurred and is continuing,

(a)

the purchase, redemption or other acquisition, cancellation or retirement for value of Capital Stock, or options, warrants, equity appreciation rights or other rights to purchase or acquire Capital Stock of the Company or any Restricted Subsidiary held by any existing or former employees or management of the Company or any Subsidiary of the Company or their assigns, estates or heirs, in each case in connection with the repurchase provisions under employee stock option or stock purchase agreements or other agreements to compensate management employees; provided that such redemptions or repurchases pursuant to this clause will not exceed $1.0 million in the aggregate during any calendar year and $3.0 million in the aggregate for all such redemptions and repurchases; provided, however, that the amount of any such repurchase or redemption will be included in subsequent calculations of the amount of Restricted Payments; and

(b)

loans or advances to employees or directors of the Company or any Subsidiary of the Company the proceeds of which are used to purchase Capital Stock of the Company, in an aggregate amount not in excess of $1.0 million at any one time outstanding; provided, however, that the Company and its Subsidiaries will comply in all material respects with all applicable provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith in connection with such loans or advances; provided, further, that the amount of such loans and advances will be included in subsequent calculations of the amount of Restricted Payments;

(7)

so long as no Default or Event of Default has occurred and is continuing, the declaration and payment of dividends to holders of any class or series of Disqualified Stock of the Company issued in accordance with the terms of this Indenture to the extent such dividends are included in the definition of “Consolidated Interest Expense”; provided, however, that the payment of such dividends will be excluded from the calculation of Restricted Payments;

(8)

repurchases of Capital Stock deemed to occur upon the exercise of stock options, warrants or other convertible securities if such Capital Stock represents a portion of the exercise price thereof; provided, however, that

such repurchases will be excluded from subsequent calculations of the amount of Restricted Payments;

(9)

the purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of any Subordinated Obligation (i) at a purchase price not greater than 101% of the principal amount of such Subordinated Obligation in the event of a Change of Control in accordance with provisions similar to those of Section 3.10 or (ii) at a purchase price not greater than 100% of the principal amount thereof in accordance with provisions similar to those of Section 3.8; provided, that, prior to or simultaneously with such purchase, repurchase, redemption, defeasance or other acquisition or retirement, the Company has made the Change of Control Offer or Asset Disposition Offer, as applicable, as provided in Section 3.10 with respect to the Securities and has completed the repurchase or redemption of all Securities validly tendered for payment in connection with such Change of Control Offer or Asset Disposition Offer; and provided, further, that such repurchases will be excluded from subsequent calculations of the amount of Restricted Payments; and

(10)

Restricted Payments in an amount not to exceed $5.0 million at any one time outstanding; provided that the amount of such Restricted Payments will be included in subsequent calculations of the amount of Restricted Payments.

The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of such Restricted Payment of the asset(s) or securities proposed to be paid, transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment. The fair market value of any cash Restricted Payment shall be its face amount and the fair market value of any non-cash Restricted Payment shall be determined conclusively by the Board of Directors of the Company acting in good faith whose resolution with respect thereto shall be delivered to the Trustee, such determination to be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing if such fair market value is estimated in good faith by the Board of Directors of the Company to exceed $10.0 million. Not later than the date of making any Restricted Payment, the Company shall deliver to the Trustee an Officers’ Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by Section 3.4 were computed, together with a copy of any fairness opinion or appraisal required by this Indenture.

SECTION 3.5. Limitation on Liens. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to exist any Lien (other than Permitted Liens) upon any of its property or assets (including Capital Stock of Restricted Subsidiaries), whether owned on the date of this Indenture or acquired after that date, which Lien is securing any Indebtedness, unless contemporaneously with the Incurrence of such Liens effective provision is made to secure the Indebtedness due under this Indenture and the Securities or, in respect of Liens on any Restricted Subsidiary’s property or assets, any Subsidiary Guarantee of such Restricted Subsidiary, equally and ratably with (or prior to in the

case of Liens with respect to Subordinated Obligations or Guarantor Subordinated Obligations, as the case may be) the Indebtedness secured by such Lien for so long as such Indebtedness is so secured.

SECTION 3.6. Limitation on Sale/Leaseback Transactions. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, enter into any Sale/Leaseback Transaction unless:

(2)

the Company or such Restricted Subsidiary could have Incurred Indebtedness in an amount equal to the Attributable Indebtedness in respect of such Sale/Leaseback Transaction pursuant to Section 3.3;

(3)

the Company or such Restricted Subsidiary would be permitted to create a Lien on the property subject to such Sale/Leaseback Transaction without securing the Securities by Section 3.5; and

(4)

the Sale/Leaseback Transaction is treated as an Asset Disposition and all of the conditions of Section 3.8 (including the provisions concerning the application of Net Available Cash) are satisfied with respect to such Sale/Leaseback Transaction, treating all of the consideration received in such Sale/Leaseback Transaction as Net Available Cash for purposes of such covenant.

SECTION 3.7. Limitation on Restrictions on Distributions from Restricted Subsidiaries. The Company shall not, and shall not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to:

(1)

pay dividends or make any other distributions on its Capital Stock or pay any Indebtedness or other obligations owed to the Company or any Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock);

(2)

make any loans or advances to the Company or any Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness Incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or

(3)

transfer any of its property or assets to the Company or any Restricted Subsidiary.

The preceding provisions will not prohibit:

(i)

any encumbrance or restriction pursuant to an agreement in effect at or entered into on the Issue Date, including, without limitation, this Indenture and the Senior Secured Credit Agreement in effect on such date;

(ii)

any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement relating to any Capital Stock or Indebtedness Incurred by a Restricted Subsidiary on or before the date on which such Restricted Subsidiary was acquired by the Company (other than Capital Stock or Indebtedness Incurred as consideration in, or to provide all or any portion of the funds utilized to consummate, the transaction or series of related transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was acquired by the Company or in contemplation of the transaction) and outstanding on such date provided, that any such encumbrance or restriction shall not extend to any assets or property of the Company or any other Restricted Subsidiary other than the assets and property so acquired;

(iii)

any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement effecting a refunding, replacement or refinancing of Indebtedness Incurred pursuant to an agreement referred to in clause (i) or (ii) of this paragraph or this clause (iii) or contained in any amendment to an agreement referred to in clause (i) or (ii) of this paragraph or this clause (iii); provided, however, that the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such agreement are no less favorable in any material respect to the Holders of the Securities than the encumbrances and restrictions contained in such agreements referred to in clauses (i)or (ii) of this paragraph on the Issue Date or the date such Restricted Subsidiary became a Restricted Subsidiary, whichever is applicable;

(iv)

in the case of clause (3) of the first paragraph of this Section 3.7, any encumbrance or restriction:

(a)

that restricts in a customary manner the subletting, assignment or transfer of any property or asset that is subject to a lease, license or similar contract, or the assignment or transfer of any such lease, license or other contract;

(b)

contained in mortgages, pledges or other security agreements permitted under this Indenture securing Indebtedness of the Company or a Restricted Subsidiary to the extent such

encumbrances or restrictions restrict the transfer of the property subject to such mortgages, pledges or other security agreements; or

(c)

pursuant to customary provisions restricting dispositions of real property interests set forth in any reciprocal easement agreements of the Company or any Restricted Subsidiary;

(v)

purchase money obligations for property acquired in the ordinary course of business and (b) Capitalized Lease Obligations permitted under this Indenture, in each case, that impose encumbrances or restrictions of the nature described in clause (3) of the first paragraph of this Section 3.7 on the property so acquired;

(vi)

any restriction with respect to a Restricted Subsidiary (or any of its property or assets) imposed pursuant to an agreement entered into for the direct or indirect sale or disposition of all or substantially all the Capital Stock or assets of such Restricted Subsidiary (or the property or assets that are subject to such restriction) pending the closing of such sale or disposition;

(vii)

customary encumbrances or restrictions imposed pursuant to any agreement referred to in the definition of “Permitted Business Investment”;

(viii)

net worth provisions in leases and other agreements entered into by the Company or any Restricted Subsidiary in the ordinary course of business; and

(ix)

SECTION 3.8. Limitation on Sales of Assets and Subsidiary Stock. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless:

(1)

the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Disposition at least equal to the fair market value (such fair market value to be determined on the date of contractually agreeing to such Asset Disposition), as determined in good faith by the Board of Directors (including as to the value of all non-cash consideration), of the shares and assets subject to such Asset Disposition;

(2)

at least 75% of the consideration from such Asset Disposition received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; and

(3)

an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company or such Restricted Subsidiary, as the case may be:

(a)

first, to the extent the Company or any Restricted Subsidiary, as the case may be, elects (or is required by the terms of any Indebtedness), to prepay, repay or purchase Indebtedness of the Company (other than any Disqualified Stock or Subordinated Obligations) or Indebtedness of a Wholly-Owned Subsidiary (other than any Disqualified Stock or a Guarantor Subordinated Obligation of a Wholly-Owned Subsidiary Guarantor) (in each case other than Indebtedness owed to the Company or an Affiliate of the Company) within 360 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; provided, however, that, in connection with any prepayment, repayment or purchase of Indebtedness pursuant to this clause (a), the Company or such Restricted Subsidiary will retire such Indebtedness and will cause the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased; and

(b)

second, to the extent of the balance of such Net Available Cash after application in accordance with clause (a), to the extent the Company or such Restricted Subsidiary elects, to invest in Additional Assets within 360 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash;

provided that pending the final application of any such Net Available Cash in accordance with clauses (a) or (b) above, the Company and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise invest such Net Available Cash in any manner not prohibited by this Indenture.

(b) Any Net Available Cash from Asset Dispositions that is not applied or invested as provided in the preceding paragraph will be deemed to constitute “Excess Proceeds.” On the 361^st day after an Asset Disposition, if the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company will be required to make an offer (“Asset Disposition Offer”) to all Holders of Securities and to the extent required by the terms of other Pari Passu Indebtedness, to all holders of other Pari Passu Indebtedness outstanding with similar provisions requiring the Company to make an offer to purchase such Pari Passu Indebtedness with the proceeds from any Asset Disposition (“Pari Passu Notes”), to purchase the maximum principal amount of Securities and any such Pari Passu Notes to which the Asset Disposition Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Securities and Pari Passu Notes plus accrued and unpaid interest to the date of purchase, in accordance with the procedures set forth in this Indenture or the agreements governing the Pari Passu Notes, as applicable, in each case in integral multiples of $1,000. To the extent that the aggregate amount of Securities and Pari Passu Notes so validly tendered and not

properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes, subject to the other covenants contained in this Indenture. If the aggregate principal amount of Securities surrendered by Holders thereof and other Pari Passu Notes surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Trustee shall select the Securities to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Securities and Pari Passu Notes. Upon completion of such Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero.

(c) (1) The Asset Disposition Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Asset Disposition Offer Period”). No later than five Business Days after the termination of the Asset Disposition Offer Period (the “Asset Disposition Purchase Date”), the Company will purchase the principal amount of Securities and Pari Passu Notes required to be purchased pursuant to this Section 3.8 (the “Asset Disposition Offer Amount”) or, if less than the Asset Disposition Offer Amount has been so validly tendered, all Securities and Pari Passu Notes validly tendered in response to the Asset Disposition Offer.

(2) If the Asset Disposition Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders of the Securities who tender Securities pursuant to the Asset Disposition Offer.

(3) On or before the Asset Disposition Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Asset Disposition Offer Amount of Securities and Pari Passu Notes or portions of Securities and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to the Asset Disposition Offer, or if less than the Asset Disposition Offer Amount has been validly tendered and not properly withdrawn, all Securities and Pari Passu Notes so validly tendered and not properly withdrawn, in each case in integral multiples of $1,000. The Company will deliver to the Trustee an Officers’ Certificate stating that such Securities or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.8 and, in addition, the Company will deliver all certificates and notes required, if any, by the agreements governing the Pari Passu Notes. The Company or the Paying Agent, as the case may be, will promptly (but in any case not later than five Business Days after the termination of the Asset Disposition Offer Period) mail or deliver to each tendering Holder of Securities or holder or lender of Pari Passu Notes, as the case may be, an amount equal to the purchase price of the Securities or Pari Passu Notes so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Company for purchase, and the Company will promptly issue a new Security, and the Trustee, upon delivery of an Officers’ Certificate from the Company, will authenticate and mail or deliver such new Security to such Holder, in a principal amount equal to any unpurchased portion of the Security surrendered; provided that each such new Security will be in a principal amount of $1,000 or an integral multiple of $1,000. In addition, the Company will take any and all other actions required by the agreements governing the Pari Passu Notes. Any Security not so accepted will be promptly mailed or delivered by the Company to the

Holder thereof. The Company will publicly announce the results of the Asset Disposition Offer on the Asset Disposition Purchase Date.

For the purposes of this Section 3.8, the following will be deemed to be cash:

(1)

the assumption by the transferee of Indebtedness (other than Subordinated Obligations or Disqualified Stock) of the Company or Indebtedness of a Wholly-Owned Subsidiary (other than Guarantor Subordinated Obligations or Disqualified Stock of any Wholly-Owned Subsidiary that is a Subsidiary Guarantor) and the release of the Company or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition (in which case the Company will, without further action, be deemed to have applied such deemed cash to Indebtedness in accordance with clause (3)(a) above); and

(2)

securities, notes or other obligations received by the Company or any Restricted Subsidiary from the transferee that are promptly converted by the Company or such Restricted Subsidiary into cash.

(1)

at the time of entering into such Asset Swap and immediately after giving effect to such Asset Swap, no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof;

(2)

in the event such Asset Swap involves the transfer by the Company or any Restricted Subsidiary of assets having an aggregate fair market value, as determined by the Board of Directors of the Company in good faith, in excess of $5.0 million, the terms of such Asset Swap have been approved by a majority of the members of the Board of Directors of the Company; and

(3)

(d) The Company will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section 3.8.

(2)

in the event such Affiliate Transaction involves an aggregate consideration in excess of $5.0 million, the terms of such transaction have been approved by a majority of the members of the Board of Directors of the Company and by a majority of the members of such Board having no personal stake in such transaction, if any (and such majority or majorities, as the case may be, determines that such Affiliate Transaction satisfies the criteria in clause (1) above); and

(3)

in the event such Affiliate Transaction involves an aggregate consideration in excess of $15.0 million, the Company has received a written opinion from an independent investment banking, accounting or appraisal firm of nationally recognized standing that such Affiliate Transaction is not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate.

(7)

the provision of drilling services by Big Dog or a successor entity to the Company or any of its Restricted Subsidiaries so long as the terms of such Affiliate Transaction are no less favorable to the Company or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable transaction at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate.

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

(5)

that on the Redemption Date the redemption price (and accrued interest, if any, to the Redemption Date payable as provided in Section 5.7) will become due and payable upon each such Security, or the portion thereof, to be redeemed, and, unless the Company defaults in making the redemption payment, that interest on Securities called for redemption (or the portion thereof) will cease to accrue on and after said date,

(6)

the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued interest, if any,

(7)

the name and address of the Paying Agent,

(8)

that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price,

SECTION 5.6. Deposit of Redemption Price. Prior to 10:00 a.m. New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.4) an amount of money sufficient to pay the redemption price of, and accrued interest on, all the Securities which are to be redeemed on that date.

SECTION 5.7. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the redemption price therein specified (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the redemption price, together with accrued interest, if any, to the Redemption Date (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Securities.

SECTION 5.8. Securities Redeemed in Part. Any Security which is to be redeemed only in part (pursuant to the provisions of this Article) shall be surrendered at the office or agency of the Company maintained for such purpose pursuant to Section 3.15 (with, if the Company or the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Company duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security at the expense of the Company, a new Security or Securities, of any authorized denomination as requested by such Holder, in an aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered, provided, that each such new Security will be in a principal amount of $1,000 or integral multiple thereof.

ARTICLE VI

(a)

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

(b)

results in the acceleration of such Indebtedness prior to its maturity (the “cross acceleration provision”);

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 $10.0 million or more;

(7)

(a) the Company or any Significant Subsidiary or a 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:

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

(i)

is for relief against the Company or any Significant Subsidiary or a 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;

(ii)

appoints a Custodian of the Company or any Significant Subsidiary or a 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 property; or

(iii)

orders the winding up or liquidation of the Company or any Significant Subsidiary or a 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, decree or relief remains unstayed and in effect for 60 days;

(8)

failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $10.0 million (net of any amounts that a reputable and creditworthy insurance company has acknowledged liability for in writing), which judgments are not paid, discharged or stayed for a period of 60 days (the “judgment default provision”);

(9)

any Subsidiary Guarantee of 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 shall cease to be in full force and effect (except pursuant to the release or termination of any such Subsidiary Guarantee in accordance with this Indenture) or shall be held to be null and void in a judicial proceeding; or any Subsidiary Guarantor that is a Significant Subsidiary or group of Subsidiary Guarantors that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary shall assert that any its Subsidiary Guarantee is not enforceable or valid or otherwise denies or disaffirms its obligations under this Indenture or its Subsidiary Guarantee.

However, a Default under clauses (4) and (5) of this Section 6.1 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 and, in the case of a notice given by the Holders, the Trustee of the Default and the Company does not cure such Default within the time specified in clauses (4) and (5) of this Section 6.1 after receipt of such notice.

SECTION 6.2. Acceleration. If an Event of Default (other than an Event of Default described in clause (7) of Section 6.1) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Securities to be due and payable. Upon such a declaration, such principal, premium and accrued and unpaid interest will be due and payable immediately. In the event of a declaration of acceleration of the Securities because an Event of Default described in clause (6) of Section 6.1 has occurred and is continuing, the declaration of acceleration of the Securities shall be automatically annulled if the event of default or payment default triggering such Event of Default pursuant to clause (6) of Section 6.1 shall be remedied or cured by the Company or a Restricted Subsidiary or waived by the holders of the relevant Indebtedness within 20 days after the declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of the Securities would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, except nonpayment of principal, premium or interest on

the Securities that became due solely because of the acceleration of the Securities, have been cured or waived. If an Event of Default described in clause (7) of Section 6.1 above occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all the Securities will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of the outstanding Securities may waive any or all past defaults (except with respect to nonpayment of principal, premium or interest) and rescind any such acceleration with respect to the Securities and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Securities that have become due solely by such declaration of acceleration, have been cured or waived.

SECTION 6.3. 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 premium, if any) 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.

SECTION 6.4. Waiver of Past Defaults. Subject to Section 6.2, the Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may (a) waive, by their consent (including, without limitation consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities), an existing Default or Event of Default and its consequences except (i) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest on a Security or (ii) a Default or Event of Default in respect of a provision that under Section 9.2 cannot be amended without the consent of each Securityholder affected and (b) rescind any such acceleration with respect to the Securities and its consequences if rescission would not conflict with any judgment or decree of a court of competent jurisdiction. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

SECTION 6.5. Control by Majority. The Holders of a majority in principal amount of the 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 Sections 7.1 and 7.2, 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 that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

SECTION 6.6. Limitation on Suits. Subject to Section 6.7, a Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless:

(1)

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

(2)

Holders of at least 25% in principal amount of the outstanding Securities have requested that the Trustee pursue the remedy;

(3)

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

(4)

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

(5)

the Holders of a majority in principal amount of the outstanding Securities have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

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

SECTION 6.7. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture (including, without limitation, Section 6.6), the right of any Holder to receive payment of principal of, premium (if any) or interest 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 6.8. Collection Suit by Trustee. If an Event of Default specified in clauses (1) or (2) of Section 6.1 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 7.7.

SECTION 6.9. 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 Subsidiaries or its or their respective creditors or properties 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 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 7.7.

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

FIRST: to the Trustee for amounts due under Section 7.7;

SECOND: to Securityholders for amounts due and unpaid on the Securities for principal, premium, if any, 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 the Subsidiary Guarantors.

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. 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 in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by the Company, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in outstanding principal amount of the Securities.

SECTION 6.12. Additional Payments. In the case of any Event of Default occurring by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding payment of the premium that the Company would have had to pay if the Company then had elected to redeem the Securities pursuant to the optional redemption provisions of this Indenture or was required to repurchase the Securities, an equivalent premium shall also become and be immediately due and payable to the extent permitted by law upon the acceleration of the Securities.

SECTION 6.13. Waiver of Stay. Each of the Company and the Subsidiary Guarantors covenant (to the extent permitted by applicable law) 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 or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company or any Subsidiary Guarantor from paying all of any portion of the principal of (premium, if any, on) or interest on the Securities as contemplated herein, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) each of the Company and the Subsidiary Guarantors hereby expressly waive all benefit or advantage of any such law, and covenants that they will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE VII

Trustee

SECTION 7.1. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee 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; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise the rights or powers under this Indenture at the request or direction of any of the holders unless such holders have offered to the Trustee reasonable indemnity or security against loss, liability or expense.

(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, opinions or orders 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 provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such certificates and opinions to determine whether or not they conform on their face to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(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 paragraph does not limit the effect of paragraph (b) of this Section 7.1;

(2)

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

(3)

the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5.

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.1.

(f) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(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 7.1 and to the provisions of the TIA.

(i) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company.

(j) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security or indemnity satisfactory to it against the costs, expenses (including reasonable attorneys’ fees and expenses) and liabilities that might be incurred by it in compliance with such request or direction.

SECTION 7.2. Rights of Trustee. Subject to Section 7.1:

(a) The Trustee may conclusively rely on any document (whether in its original or facsimile form) reasonably believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate and/or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on an Officers’ Certificate or Opinion of Counsel.

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

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers, unless the Trustee’s conduct constitutes willful misconduct or negligence.

(e) The Trustee may consult with counsel of its selection, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

(f) The Trustee shall not be charged with knowledge of any default or Event of Default with respect to the Securities, unless either (1) a Trust Officer shall have actual knowledge of such default or Event of Default or (2) written notice of such default or Event of Default shall have been given to the Trustee by the Company or by any Holder of the Securities; and

(g) The permissive rights of the Trustee enumerated herein shall not be construed as duties.

SECTION 7.3. 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 7.4. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible 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 7.5. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if a Trust Officer has actual knowledge thereof, the Trustee shall mail to each Securityholder notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Security (including payments pursuant to the optional redemption or required repurchase provisions of such Security, if any), the Trustee may withhold notice if and so long as a committee of its Trust Officers in good faith determines that withholding notice is in the interests of Securityholders.

SECTION 7.6. Reports by Trustee to Holders. As promptly as practicable after each August 15 beginning with the August 15, following the date of this Indenture, and in any event prior to October 15 in each year for so long as the Securities remain outstanding, the Trustee shall mail to each Securityholder a brief report dated as of such August 15 that complies with TIA § 313(a). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports required by TIA § 313(c).

A copy of each report at the time of its mailing to Securityholders shall be filed with the Commission and each stock exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof.

SECTION 7.7. Compensation and Indemnity. The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder as the Company and the Trustee shall from time to time agree in writing. 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 out-of-pocket expenses incurred or made by it, including costs of collection, costs of preparing and reviewing reports, certificates and other documents, costs of preparation and mailing of notices to Securityholders, 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 against any and all loss, liability, damages, claims or expense (including reasonable attorneys’ fees and expenses) incurred by it without negligence, willful misconduct or bad faith on its part in connection with the administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture (including this Section 7.7) and of defending itself against any claims (whether asserted by any Securityholder, the Company or otherwise). 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 shall provide reasonable cooperation at the Company’s expense in the defense. The Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel provided that the Company shall not be required to pay such fees and expenses if it assumes the Trustee’s defense, and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest between the Company and the Trustee in connection with such defense. The Company shall not be under any obligation to pay for any written settlement without its consent, which consent shall not be unreasonably delayed, conditioned or withheld. 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, negligence or bad faith.

To secure the Company’s payment obligations in this Section 7.7, 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 Company’s payment obligations pursuant to this Section 7.7 shall survive the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in clause (7) of Section 6.1 with respect to the Company, the expenses are intended to constitute expenses of administration under any Bankruptcy Law. The obligations of the Company under this Section 7.7 shall survive the resignation or removal of the Trustee and the termination, satisfaction or discharge of this Indenture.

SECTION 7.8. 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 then outstanding Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if:

(1)

the Trustee fails to comply with Section 7.10;

(2)

the Trustee is adjudged bankrupt or insolvent;

(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 then outstanding Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of the 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.

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 7.7.

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 at least 10% in principal amount of the Securities may petition, at the Company’s expense, any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10, unless the Trustee’s duty to resign is stayed as provided in TIA § 310(b), any Securityholder who has been a bona fide Holder of a Security for at least six months 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 7.8, the Company’s obligations under Section 7.7 shall continue for the benefit of the retiring Trustee.

SECTION 7.9. 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 banking association, the resulting, surviving or transferee corporation 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.

SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 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 TIA § 310(b)(1) are met.

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

(a) Subject to Section 8.1(c), when (i)(x) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.7) for cancellation or (y) all outstanding Securities not theretofore delivered for cancellation have become due and payable, whether at maturity or upon redemption or will become due and payable at their Stated Maturity within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption pursuant to Article V hereof and the Company or any Subsidiary Guarantor irrevocably deposits or causes to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders money in U.S. dollars, non-callable U.S. Government Obligations, 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 such Securities not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; (ii) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit will not result in a breach or violation of, or constitute a default under, any other material instrument to which the Company is a party or by which the Company or any Subsidiary Guarantor is bound; (iii) the Company or any Subsidiary Guarantor has paid or caused to be paid all sums payable under this Indenture and the Securities; and (iv) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of such Securities at maturity or the Redemption Date, as the case may be, then the Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Company (accompanied by an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent specified herein relating to the satisfaction and discharge of this Indenture have been complied with) and at the cost and expense of the Company.

(b) Subject to Sections 8.1(c) and 8.2, the Company at any time may terminate (i) all its obligations under the Securities and this Indenture and all obligations of the Subsidiary Guarantors under the Subsidiary Guarantees and this Indenture (“legal defeasance option”), and after giving effect to such legal defeasance, any omission to comply with such obligations shall no longer constitute a Default or Event of Default or (ii) its obligations under Sections 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.13, 3.17, and 4.1(3) and the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any

reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply with such covenants shall no longer constitute a Default or an Event of Default under Section 6.1(4) and 6.1(5) and the operation of Sections 6.1(6), 6.1(7) (but only with respect to a Significant Subsidiary or group of Restricted Subsidiaries that would constitute a Significant Subsidiary), 6.1(8) and 6.1(9), and the events specified in such Sections shall no longer constitute an Event of Default (clause (ii) being referred to as the “covenant defeasance option”), but except as specified above, the remainder of this Indenture and the Securities shall be unaffected thereby. The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.

If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default with respect to the Securities, and the Subsidiary Guarantees in effect at such time shall terminate. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Section 6.1(4) (as such Section relates to 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.13, and 3.17), 6.1(5), 6.1(6), 6.1(7) (but only with respect to a Significant Subsidiary or group of Restricted Subsidiaries that would constitute a Significant Subsidiary), 6.1(8) or 6.1(9) or because of the failure of the Company to comply with Section 4.1(3).

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates.

(c) Notwithstanding the provisions of Sections 8.1(a) and (b), the Company’s obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.1, 3.14, 3.15, 3.16, 3.18, 3.19, 3.20, 6.7, 7.7, 7.8 and in this Article VIII shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.7, 8.4 and 8.5 shall survive.

SECTION 8.2. Conditions to Defeasance. The Company may exercise its legal defeasance option or its covenant defeasance option only if:

(1)

the Company irrevocably deposits in trust with the Trustee for the benefit of the Holders money in U.S. dollars or U.S. Government Obligations or a combination thereof for the payment of principal, premium, if any, and interest on the Securities to maturity or redemption, as the case may be;

(2)

the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal, premium, if any, and interest when due on all the Securities to maturity;

(3)

no Default or Event of Default shall have occurred and be continuing on the date of such deposit or, with respect to the Company under Section 6.1(7), on the 123rd day after such date of deposit;

(4)

such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a Default under, this Indenture or any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(5)

the Company shall have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) to the effect that (A) the Securities and (B) assuming no intervening bankruptcy of the Company between the date of deposit and the 123rd day following the deposit and that no Holder of the Securities is an insider of the Company within the meaning of the Bankruptcy Law, after the 123rd day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ right generally;

(6)

the Company delivers to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940;

(7)

in the case of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) in the United States stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Securityholders will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred;

(8)

in the case of the covenant defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) in the United States to the effect that the Securityholders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and covenant defeasance and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and covenant defeasance had not occurred; and

(9)

the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities and this Indenture as contemplated by this Article VIII have been complied with.

SECTION 8.3. Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article VIII. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities.

SECTION 8.4. Repayment to Company. The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money, U.S. Government Obligations or securities held by them upon payment of all the obligations under this Indenture.

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

SECTION 8.5. Indemnity for U.S. Government Obligations. The Company shall pay and shall indemnify the Trustee 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.

SECTION 8.6. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article VIII by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company and the Subsidiary Guarantors under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article VIII; provided, however, that, if the Company has made any payment of interest on or principal of any Securities because of the reinstatement of its 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 Trustee or Paying Agent.

ARTICLE IX

Amendments

SECTION 9.1. Without Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may amend this Indenture, the Securities or the Subsidiary Guarantees without notice to or consent of any Securityholder:

(1)

to cure any ambiguity, omission, defect or inconsistency;

(2)

to provide for the assumption by a Successor Company of an obligation of the Company or any Subsidiary Guarantor under this Indenture in compliance with Article IV;

(3)

to provide for uncertificated Securities in addition to or in place of certificated Securities (provided that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Securities are described in Section 163(f) (2) (B) of the Code);

(4)

to add Guarantees with respect to the Securities or release a Subsidiary Guarantor upon its designation as an Unrestricted Subsidiary; provided, however, that the designation is in accordance with the terms of this Indenture;

(5)

to secure the Securities;

(6)

to add to the covenants of the Company for the benefit of the Holders or to surrender any right or power herein conferred upon the Company;

(7)

to make any change that does not adversely affect the rights of any Securityholder;

(8)

to comply with any requirement of the Commission in connection with qualifying, or maintaining the qualification of this Indenture, under the Trust Indenture Act; or

(9)

to provide for the issuance of Exchange Securities.

After an amendment under this Section 9.1 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 9.1.

SECTION 9.2. With Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture or the Securities without notice to any Securityholder but with the written consent of the Holders of at least a majority in principal amount of the Securities then outstanding (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 Securityholder affected, an amendment may not:

(1)

reduce the principal amount of Securities whose Holders must consent to an amendment;

(2)

reduce the stated rate of or extend the stated time for payment of interest on any Security;

(3)

reduce the principal of or extend the Stated Maturity of any Security;

(4)

reduce the premium payable upon the redemption or repurchase of any Security as described under Article V, Section 3.8, Section 3.10 or change the time at which any Security may be redeemed or repurchased as described under Article V, or make any change to the provisions relating to a Change of Control Offer in respect of a Change of Control that has occurred or make any change to the provisions relating an Asset Disposition Offer that has been made, in each case whether through an amendment or waiver of provisions in the covenants, definitions or otherwise;

(5)

make any Security payable in currency other than that stated in the Security;

(6)

impair the right of any Holder to receive payment of, premium, if any, principal of and interest on such Holder’s Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities;

(7)

make any change in the amendment provisions which require each Holder’s consent or in the waiver provisions; or

(8)

modify the Subsidiary Guarantees in any manner adverse to the Holders of the Securities.

It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof. A consent to any amendment or waiver under this Indenture by any Holder of the Securities given in connection with a tender of such Holder’s Securities will not be rendered invalid by such tender.

After an amendment under this Section 9.2 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 9.2.

SECTION 9.3. Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Securities shall comply with the TIA as then in effect.

SECTION 9.4. 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 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 shall become

effective upon receipt by the Trustee of the requisite number of written consents under Section 9.1 or 9.2 as applicable.

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 become valid or effective more than 120 days after such record date.

SECTION 9.5. Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee 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 9.6. Trustee To Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article IX if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive, in addition to the documents required by Section 11.4, and (subject to Sections 7.1 and 7.2) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

ARTICLE X

Subsidiary Guarantee

SECTION 10.1. Subsidiary Guarantee. Each Subsidiary Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly and severally with each other Subsidiary Guarantor, to each Holder of the Securities and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, and interest on the Securities and all other monetary obligations of the Company under this Indenture (all the foregoing being hereinafter collectively called the “Obligations”). Each Subsidiary Guarantor further agrees (to the extent permitted by law) that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it will remain bound under this Article X notwithstanding any extension or renewal of any Obligation.

Each Subsidiary Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Obligations and also waives notice of protest for

nonpayment. Each Subsidiary Guarantor waives notice of any default under the Securities or the Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Company or any other person under this Indenture, the Securities or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Obligations or any of them; (e) the failure of any Holder to exercise any right or remedy against any other Subsidiary Guarantor; or (f) any change in the ownership of the Company.

Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein constitutes a Guarantee of payment when due (and not a Guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Obligations.

Except as expressly set forth in Sections 8.1(b) and 10.2, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), 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 Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder 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 any Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

Each Subsidiary Guarantor further agrees that its Subsidiary 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 or interest on any of the Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay any of the Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Subsidiary Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders an amount equal to the sum of (i) the unpaid amount of such Obligations then due and owing and (ii) accrued and unpaid interest on such Obligations then due and owing (but only to the extent not prohibited by law) and except as provided in Section 10.2.

Each Subsidiary Guarantor further agrees that, as between such Subsidiary Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the

Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantor for the purposes of this Subsidiary Guarantee.

Each Subsidiary Guarantor also agrees to pay any and all reasonable costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or the Holders in enforcing any rights under this Section 10.1.

SECTION 10.2. Limitation on Liability; Termination, Release and Discharge.

(a) The obligations of each Subsidiary Guarantor hereunder will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor (including, but not limited to, Guarantor Senior Indebtedness) and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under Federal or state law.

(b) Subject to Section 3.8 and Article IV, each Subsidiary Guarantor may consolidate with or merge into or sell all or substantially all of its property and assets to the Company or another Subsidiary Guarantor without limitation. Subject to Section 3.8 and Article IV, each Subsidiary Guarantor may consolidate with or merge into or sell all or substantially all its assets to a Person other than the Company or another Subsidiary Guarantor (whether or not Affiliated with the Subsidiary Guarantor), except that if the surviving Person of any such merger or consolidation is a Subsidiary of the Company, such merger, consolidation or sale shall not be permitted unless (i) the Person formed by or surviving any such consolidation or merger assumes all the obligations of such Subsidiary under the Subsidiary Guarantee pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee in respect of the Securities, this Indenture and the Subsidiary Guarantee; (ii) immediately after giving effect to such transaction no covenants under Article III are violated; (iii) immediately after giving effect to such transaction, no Default or Event of Default exists; and (iii) the Company deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel addressed to the Trustee with respect to the foregoing matters. Upon the sale or disposition of a Subsidiary Guarantor (by merger, consolidation, the sale of its Capital Stock or the sale of all or substantially all of its properties and assets (other than by lease)), whether or not the Subsidiary Guarantor is the surviving corporation in such transaction, to a Person (whether or not an Affiliate of the Subsidiary Guarantor) which is not the Company or a Restricted Subsidiary of the Company, which sale or disposition is otherwise in compliance with this Indenture (including, without limitation, Sections 3.4, 3.8 and 3.11), such Subsidiary Guarantor will be deemed released from all its Subsidiary Guarantor obligations under all of its pledge of assets or other security interests which secure other indebtedness of the company will also terminate; provided, however, that any such termination will occur only to the extent that all obligations of such Subsidiary Guarantor under the Senior Secured Credit Agreement and any other agreements relating to any other

Indebtedness of the Company or its Restricted Subsidiaries will also terminate upon such release, sale or transfer.

(c) A Subsidiary Guarantor will be deemed released and relieved of its obligations under this Indenture and its Subsidiary Guarantee without any further action required on the part of the Company or such Subsidiary Guarantor upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture.

SECTION 10.3. Limitation of Subsidiary Guarantors’ Liability. Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby confirm that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal or state law. To effectuate the foregoing intention, the Holders and each Subsidiary Guarantor hereby irrevocably agree that the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities (including, but not limited to, Guarantor Senior Indebtedness) of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to Section 10.4 hereof, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting such a fraudulent conveyance or fraudulent transfer. This Section 10.3 is for the benefit of the creditors of each Subsidiary Guarantor.

SECTION 10.4. Contribution. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, that in the event any payment or distribution is made by any Subsidiary Guarantor (a “Funding Guarantor”) under its Subsidiary Guarantee, such Funding Guarantor will be entitled to a contribution from each other Subsidiary Guarantor (if any) in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s obligations with respect to the Securities or any other Subsidiary Guarantor’s obligations with respect to its Subsidiary Guarantee.

[FORM OF REVERSE SIDE OF UNREGISTERED NOTE]

7% Senior Notes due 2015

Interest

DELTA PETROLEUM CORPORATION, a Colorado corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above.

The Company will pay interest semiannually on April 1 and October 1 of each year commencing October 1, 2005. Interest on the Securities will accrue from the most recent date to which interest has been paid on the Securities or, if no interest has been paid, from [ ]. The Company shall pay interest on overdue principal or premium, if any (plus interest on such interest to the extent lawful), at the rate borne by the Securities to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2.	Method of Payment

By no later than 10:00 a.m. (New York City time) on the date on which any principal of or interest on any Security is due and payable, the Company shall irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay such principal, premium, if any, and/or interest. The Company will pay interest (except Defaulted Interest) to the Persons who are registered Holders of Securities at the close of business on the March 15 or September 15 next preceding the interest payment date even if Securities are cancelled, repurchased or redeemed after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of Securities represented by a Global Security (including principal, premium, if any, and interest) will be made by the transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company shall make all payments in respect of a Definitive Security (including principal, premium, if any, and interest) at the office or agency of the Company maintained for such purpose in The City of New York, or at such other office or agency of the Company as may be maintained for such purpose pursuant to the Indenture; provided, however, that, at the option of the Company, each installment of interest may be paid by (i) check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Note Register or (ii) wire transfer to an account located in the United States maintained by the payee.

3.	Paying Agent and Registrar

Initially, U.S. BANK NATIONAL ASSOCIATION (the “Trustee”) will act as Trustee, Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice to any Securityholder. The Company or any of its Subsidiaries may act as Paying Agent, Registrar or co-registrar.

A-3

Indenture

The Company issued the Securities under an Indenture dated as of March 15, 2005 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Trust Indenture Act”; provided, however, that in the event the Trust Indenture Act is amended after such date, “Trust Indenture Act” shall mean, to the extent required by any such amendment, the Trust Indenture Act of 1939 as so amended). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Trust Indenture Act for a statement of those terms.

The Securities are general unsecured senior obligations of the Company. The aggregate principal amount of securities that may be authenticated and delivered under the Indenture is unlimited. This Security is one of the 7% Senior Notes due 2015 referred to in the Indenture. The Securities include (i) $150,000,000 aggregate principal amount of the Company’s 7% Senior Notes due 2015 issued under the Indenture on March 15, 2005 (herein called “Initial Securities”), (ii) if and when issued, additional 7% Senior Notes due 2015 of the Company that may be issued from time to time under the Indenture subsequent to March 15, 2005 (herein called “Additional Securities”) and (iii) if and when issued, the Company’s 7% Senior Notes due 2015 that may be issued from time to time under the Indenture in exchange for Initial Securities or Additional Securities in an offer registered under the Securities Act as provided in the Registration Rights Agreement. The Initial Securities, Additional Securities and Exchange Securities are treated as a single class of securities under the Indenture. This Indenture imposes certain limitations on, among other things, the Incurrence of Indebtedness by the Company and its Subsidiaries, the payment of dividends and other distributions on the Capital Stock of the Company and its Subsidiaries, the purchase or redemption of Capital Stock of the Company, certain purchases or redemptions of Subordinated Indebtedness, the sale or transfer of assets and Capital Stock of Subsidiaries, certain sale/leaseback transactions involving the Company or any Restricted Subsidiary, the issuance or sale of Capital Stock of Subsidiaries, the incurrence of certain Liens, certain payment guarantees, the business activities and investments of the Company and its Subsidiaries and transactions with Affiliates. In addition, the Indenture limits the ability of the Company and its Restricted Subsidiaries to enter into agreements that restrict distributions and dividends from Restricted Subsidiaries.

To guarantee the due and punctual payment of the principal, premium, if any, and interest on the Securities and all other amounts payable by the Company under the Indenture and the Securities when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, the Subsidiary Guarantors have unconditionally guaranteed (and future Subsidiary Guarantors, together with the Subsidiary Guarantors, will unconditionally guarantee), jointly and severally, such obligations on a unsecured senior basis pursuant to the terms of the Indenture.

A-4

5.	Redemption

Except as set forth below, the Securities will not be redeemable at the option of the Company prior to April 1, 2010. On and after such date, the Securities will be redeemable, at the Company’s option, in whole or in part, at any time upon not less than 30 nor more than 60 days prior notice mailed by first-class mail to each Holder’s registered address, at the following redemption prices (expressed in percentages of principal amount), plus accrued and unpaid interest to the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date):

If redeemed during the twelve-month period commencing on April 1 of the years set forth below:


Period		Redemption Price
2010		103.500%
2011		102.333%
2012		101.167%
2013 and thereafter		100.000%

In addition, at any time and from time to time prior to April 1, 2008, the Company may redeem in the aggregate up to 35% of the original principal amount of the Securities with the Net Cash Proceeds of one or more Equity Offerings received by the Company at a redemption price (expressed as a percentage of principal amount) of 107.000% plus accrued and unpaid interest, if any, to the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, however, that there is a Public Market at the time of such Redemption; provided further, that at least 65% of the original principal amount of the Securities must remain outstanding after each such redemption; provided further, that each such redemption occurs within 60 days of the date of closing of such Equity Offering.

If the optional Redemption Date is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest, if any, will be paid to the Person in whose name the Security is registered at the close of business on such record date, and no additional interest will be payable to Holders whose Securities will be subject to redemption by the Company.

A-5

In the case of any partial redemption, selection of the Securities for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Securities are listed or, if the Securities are not listed, then on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem to be fair and appropriate, although no Securities of $1,000 in original principal amount or less will be redeemed in part. If any Security is to be redeemed in part only, the notice of redemption relating to such Security shall state the portion of the principal amount thereof to be redeemed. A new Security in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Security. On and after the Redemption Date, interest will cease to accrue on Securities or portions thereof called for redemption as long as the Company has deposited with the Paying Agent funds in satisfaction of the applicable redemption price pursuant to the Indenture.

6.	Repurchase Provisions

(a) Upon a Change of Control each Holder of Securities will have the right to cause the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of the Securities of such Holder at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture.

(b) In the event of an Asset Disposition that requires the purchase of Securities pursuant to Section 3.8(b) of the Indenture, the Company will be required to apply such Excess Proceeds to the repayment of the Securities and any Pari Passu Notes in accordance with the procedures set forth in Section 3.8 of the Indenture.

7.	Denominations; Transfer; Exchange

The Securities are in registered form without coupons in denominations of principal amount of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Security for a period beginning (i) 15 days before the selection of Securities to be repurchased or redeemed and ending at the close of business on the day of such selection (except, in the case of Securities to be redeemed in part, the portion of the Security not to be redeemed) or (ii) 15 days before an interest payment date and ending on such interest payment date

8.	Persons Deemed Owners

The registered Holder of this Security may be treated as the owner of it for all purposes.

A-6

9.	Unclaimed Money

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

10.	Defeasance

Subject to certain conditions set forth in the Indenture, the Company at any time may terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be.

11.	Amendment, Waiver

Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in principal amount of the then outstanding Securities and (ii) any default (other than with respect to nonpayment or in respect of a provision that cannot be amended without the written consent of each Securityholder affected) or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount of the then outstanding Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company, the Subsidiary Guarantors and the Trustee may amend the Indenture, the Securities or the Subsidiary Guarantees to cure any ambiguity, omission, defect or inconsistency, or provide for the assumption by a Successor Company of an obligation of the Company or any Subsidiary Guarantor under the Indenture in compliance with Article IV of the Indenture, or to provide for uncertificated Securities in addition to or in place of certificated Securities, or to add guarantees with respect to the Securities or release a Subsidiary Guarantor upon its designation as an Unrestricted Subsidiary in compliance with the Indenture, to secure the Securities, or to add additional covenants of the Company, or surrender rights and powers conferred on the Company, or to comply with any request of the Commission in connection with qualifying the Indenture under the Trust Indenture Act, or to make any change that does not adversely affect the rights of any Securityholder, or to provide for the issuance of Exchange Securities.

12.	Defaults and Remedies

Under the Indenture, Events of Default include (in summary form): (i) default for 30 days in payment of interest or additional interest when due on the Securities; (ii) default in payment of principal or premium, if any, on the Securities at Stated Maturity, upon required repurchase or upon optional redemption pursuant to paragraphs 5 and 6 of the Securities, upon declaration or otherwise; (iii) the failure by the Company or any Subsidiary Guarantor to comply with its obligations under Article IV of the Indenture; (iv) failure by the Company to comply for 30 days after notice with any of its obligations under the covenants described under Sections 3.2 through 3.17 inclusive of the Indenture (in each case, other than a failure to purchase Securities, which failure shall constitute an Event of Default under clause (ii) above and other than a failure

A-7

to comply with Article IV, which failure shall constitute an Event of Default under clause (iii) above); (v) the failure by the Company or any Subsidiary Guarantor to comply for 60 days after notice with its other agreements contained in the Indenture or under the Securities (other than those referred to in (i), (ii), (iii) or (iv) above); (vi) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), other than Indebtedness owed to the Company or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists, or is created after the date of this Indenture, which default: (a) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (“payment default”); or (b) results in the acceleration of such Indebtedness prior to its maturity (the “cross acceleration provision”); 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 $10.0 million or more; (vii) certain events of bankruptcy, insolvency or reorganization of the Company or 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 (the “bankruptcy provisions”); (viii) failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $10.0 million (net of any amounts with respect to which a reputable and creditworthy insurance company has acknowledged liability for in writing), which judgments are not paid, discharged or stayed for a period of 60 days (the “judgment default provision”); or (ix) any Subsidiary Guarantee of 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 shall cease to be in full force and effect (except pursuant to the release or termination of any such Subsidiary Guarantee in accordance with this Indenture) or shall be held to be null and void in a judicial proceeding; or any Subsidiary Guarantor that is a Significant Subsidiary or group of Subsidiary Guarantors that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary shall assert that any its Subsidiary Guarantee is not enforceable or valid or otherwise denies or disaffirms its obligations under this Indenture or its Subsidiary Guarantee. However, a default under clauses (iv) and (v) will not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company and, in the case of a notice given by the Holders, the Trustee of the default and the Company does not cure such default within the time specified in clauses (iv) and (v) hereof after receipt of such notice.

If an Event of Default occurs and is continuing (other than an Event of Default described in clause (vii) above), the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable. Certain events of bankruptcy or insolvency are Events of Default which will result in the Securities being due and payable immediately upon the occurrence of such Events of Default.

A-8

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default or Event of Default (except a Default or Event of Default in payment of principal or interest) if it determines that withholding notice is in their interest.

13.	Trustee Dealings with the Company

Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its affiliates with the same rights it would have if it were not Trustee.

14.	No Recourse Against Others

An incorporator, director, officer, employee, stockholder or controlling person, as such, of the Company or any Subsidiary Guarantor shall not have any liability for any obligations of the Company or any Subsidiary Guarantor under the Securities, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

15.	Authentication

This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent acting on its behalf) manually signs the certificate of authentication on the other side of this Security.

16.	Abbreviations

Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (= joint tenants with rights of survivorship and not as tenants in common), CUST (= custodian) and U/G/M/A (= Uniform Gift to Minors Act).

17.	CUSIP Numbers

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

2. We understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities to offer, sell or otherwise transfer such Securities prior to the date that is two years after the later of the date of original issue and the last date on which the Company or any affiliate of the Company was the owner of such Securities (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) to the Company, (b) pursuant to a registration

statement which has been declared effective under the Securities Act, (c) in a transaction complying with the requirements of Rule 144A under the Securities Act, to a person we reasonably believe is a qualified institutional buyer under Rule 144A (a “QIB”) that purchases for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is purchasing for its own account or for the account of such an institutional “accredited investor,” in each case in a minimum principal amount of Securities of $250,000 or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be made pursuant to clause (e) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Company and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act) and that it is acquiring such Securities for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and the Trustee reserve the right prior to any offer, sale or other transfer prior to the Resale Restriction Termination Date of the Securities pursuant to clauses (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications and/or other information satisfactory to the Company and the Trustee.
