amalgamation or merger or resulting from such conversion (if other than the Company) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a corporation, limited liability company or limited partnership

 34 







 (b) For purposes of this Section 8.1, the sale, lease, conveyance, assignment,
transfer, or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or

such sale, transfer, assignment, conveyance or other disposition is made, shall succeed to, and be substituted for the Company (so that from and after the date of such consolidation, merger, sale, conveyance or other disposition, the provisions of
this Indenture referring to the “Company” shall refer instead to the successor corporation and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person
had been named as the Company herein. When the successor assumes all of the Company’s obligations under this Indenture, the Company shall be discharged from those obligations; provided, however, that the Company will not be
released from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the Company’s assets in a transaction that is subject to, and that complies with the provisions of, this Article Eight.

Indenture, Article Fourteen of the Original Indenture is hereby amended by adding the following Sections 14.4 and 14.5 thereto: 
 Section 14.4 Guarantors May Consolidate, etc., on Certain Terms. 
 Except as otherwise provided in
Section 14.5 of this Indenture, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (regardless of whether such Guarantor is the surviving Person) another Person,
other than the Company or another Guarantor, unless: 
 (a) immediately after giving effect to such transaction, no Default or
Event of Default exists; and 
 (b) either: 
 (i) subject to Section 14.5 hereof, if it is not such Guarantor, the Person acquiring the property in any such sale or disposition or
the Person formed by or surviving any such consolidation or merger assumes all the obligations of that Guarantor under this Indenture (including its Subsidiary Guarantee), on the terms set forth herein, pursuant to a supplemental indenture in form
and substance reasonably satisfactory to the Trustee, in which case the Subsidiary Guarantee of such Guarantor will be released as contemplated by Section 14.5 of this Indenture; or 
  

 37 







 (ii) the Net Proceeds of such sale or other disposition are applied in accordance with
the applicable provisions of this Indenture, including without limitation Section 10.12. 
 In case of any such
consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee of such Guarantor and
the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named
herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Subsidiary Guarantee notations to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee. All the Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this
Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof. 
 Except as set
forth in Articles Eight and Ten of this Indenture, and notwithstanding clauses (i) and (ii) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company
or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor. 
 Section 14.5 Releases. 
 (a) In the event of any sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Capital Stock of any Guarantor, in each
case to a Person that is not (either before or after giving effect to such transactions) the Company or a Restricted Subsidiary of the Company, then such Guarantor (in the event of a sale or other disposition, by way of merger, consolidation or
otherwise, of all of the Capital Stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor) will be released and relieved of any
obligations under its Subsidiary Guarantee, provided that the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including without limitation Section 10.12. Upon
delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with the provisions of this Indenture, including without
limitation Section 10.12, the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee. 
 (b) In addition, each Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee: 
 (i) upon designation of such Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture; 
 (ii) upon Legal Defeasance in accordance with Article Thirteen of this Indenture or satisfaction and discharge of this Indenture in
accordance with Article Four of this Indenture;

response to the Repurchase Offer. Payment for any Notes so purchased shall be made in the same manner as interest payments are made. 
 (b) If the Purchase Date is on or after an interest record date and on or before the related Interest Payment Date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on
such record date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Repurchase Offer. 
 (c) Upon the commencement of a Repurchase Offer, the Company shall send, by first class mail, a notice to the Trustee and each of the Holders of Notes. The notice shall contain all instructions and materials necessary to enable such Holders
to tender Notes pursuant to the Repurchase Offer. The Repurchase Offer shall be made to all Holders of Notes. The notice, which shall govern the terms of the Repurchase Offer, shall state:

receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased; 
 (viii) that, if the aggregate amount of Notes surrendered
by Holders exceeds the Offer Amount, the Trustee shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $1,000, or and integral multiples
thereof, shall be purchased); and 
 (ix) that Holders whose Notes were purchased only in part shall be issued new Notes equal
in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book entry transfer). 
 (d) On the
Purchase Date, the Company shall, to the extent lawful, accept for payment on a pro rata basis to the extent necessary, the Offer Amount of Notes (or portions thereof) tendered pursuant to the Repurchase Offer, or if less than the Offer Amount has
been tendered, all Notes tendered, and shall deliver to the Trustee an Officers’ Certificate stating that such Notes (or portions thereof) were accepted for payment by the Company in accordance with the terms of this Article Fifteen. The
Company, the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not later than three days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of Notes tendered by
such Holder, as the case may be, and accepted by the Company for purchase, and the Company shall promptly issue a new Note. The Trustee, upon written request from the Company shall authenticate and mail or deliver such new Note to such Holder, in a
principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the respective Holder thereof. The Company shall publicly announce the results of the

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

repaid with cash on or prior to the date of determination) or from the substantially concurrent contribution of common equity capital to the Company; provided that the amount of any such net cash proceeds that are utilized for any such
Restricted Payment will be excluded from clause (iii)(B) of Section 10.9(a);

 (x) the payment of any dividend (or, in the case
of any partnership or limited liability company, any similar distribution) by a Restricted Subsidiary to the holders (other than the Company or any Restricted Subsidiary) of Equity Interests (other than Disqualified Stock) of such Restricted

 (xi) any Restricted Payment as long as on the date of such Restricted Payment, after giving pro forma effect thereto and to any related

2.5 to 1; 
 (xii) the purchase or redemption of any Acquired Subordinated Indebtedness of the Company or any of its

obligations under Section 10.15; or 
 (B) in the case of an Asset Sale, the Company has complied with and fully
satisfied its obligations under Section 10.12; or 
 (xiv) other Restricted Payments in an amount not to exceed $50.0
million. 
  

 45 







 (c) 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. 
 (d) 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 exceeding $15.0 million shall be determined conclusively by two Officers of the Company acting in good faith whose conclusions with respect thereto shall be set forth in an Officers’ Certificate delivered to the Trustee,
provided, however, that if the Fair Market Value of any non-cash Restricted Payment exceeds $40.0 million, such Fair Market Value shall be determined conclusively by the Board of Directors of the Company and set forth in a Board
Resolution, and a certified copy of such Board Resolution shall be delivered to the Trustee. For purposes of determining compliance with this covenant, in the event that a Restricted Payment meets the criteria of more than one of the exceptions
described in clauses (i) through (xiv) of Section 10.9(b) or is entitled to be made pursuant to Section 10.9(a), the Company shall, in its sole discretion, classify such Restricted Payment, or later classify, reclassify or

 SECTION 4.04.
Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. 
 Subject to the
limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further amended by adding the following Section 10.10 thereto: 
 Section 10.10 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or
become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
 (i) pay
dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Company
or any of its Restricted Subsidiaries; 
 (ii) make loans or advances to the Company or any of its Restricted Subsidiaries; or

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

under or by reason of: 
 (i) agreements governing Existing Indebtedness and Credit Facilities as in effect on March 13,
2007 and any amendments, restatements, modifications, renewals, supplements, increases, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals, supplements, increases,
refundings, replacements or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on March 13, 2007; 
 (ii) this Indenture, the Notes and the Subsidiary Guarantees; 
  

 46 







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

 (iv) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted
Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be
incurred; 
 (v) customary non-assignment provisions in contracts, leases and licenses (including, without limitation,
licenses of intellectual property) entered into in the ordinary course of business; 
 (vi) any agreement for the sale or
other disposition of assets, including without limitation an agreement for the sale or other disposition of the Capital Stock or assets of a Restricted Subsidiary, that restricts distributions by the applicable Restricted Subsidiary pending the sale
or other disposition; 
 (vii) Permitted Refinancing Indebtedness; provided that the restrictions contained in the
agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; 
 (viii) Liens permitted to be incurred under the provisions of Section 10.14 that limit the right of the debtor to dispose of the
assets subject to such Liens; 
 (ix) the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends
thereon in accordance with the terms thereof; provided that issuance of such preferred stock is permitted pursuant to Section 10.11 and the terms of such preferred stock do not expressly restrict the ability of a Restricted Subsidiary to
pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred stock prior to paying any dividends or making any other distributions on such other Capital
Stock); 
 (x) other Indebtedness of the Company or any of its Restricted Subsidiaries permitted to be incurred pursuant to an
agreement entered into subsequent to March 13, 2007 in accordance with Section 10.11; provided that the provisions relating to such encumbrance or restriction contained in such Indebtedness are not materially less favorable to the
Company and its Restricted Subsidiaries taken as a whole, as determined by the Company in good faith, than the provisions contained in the Credit Facilities and in this Indenture as in effect on March 13, 2007; 
 (xi) customary provisions restricting subletting or assignment of any lease governing a leasehold interest; 
 (xii) Hedging Obligations permitted from time to time under this Indenture;

 (A) customary nonassignment provisions (including provisions forbidding subletting)
in leases governing leasehold interests or Farm-In Agreements or Farm-Out Agreements relating to leasehold interests in oil and gas properties to the extent such provisions restrict the transfer of the lease, the property leased thereunder or the
other interests therein; 
 (B) provisions limiting the disposition or distribution of assets or property in, or transfer of
Capital Stock of, joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into (1) in the ordinary course of business, consistent with past practice or (2) with
the approval of the Company’s Board of Directors, which limitations are applicable only to the assets, property or Capital Stock that are the subject of such agreements; and 
 (C) Capital Lease Obligations, security agreements, mortgages, purchase money agreements or similar instruments to the extent such
encumbrance or restriction restricts the transfer of the property (including Capital Stock) subject to such Capital Lease Obligations, security agreements, mortgages, purchase money agreements or similar instruments. 
 SECTION 4.05. Incurrence of Indebtedness and Issuance of Preferred Stock. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further
amended by adding the following Section 10.11 thereto: 
 Section 10.11 Incurrence of Indebtedness and Issuance of Preferred
Stock. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly,
create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur,” with “incurrence” having a correlative meaning) any Indebtedness
(including Acquired Debt), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur Indebtedness
(including Acquired Debt) and issue Disqualified Stock, and Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) and issue preferred stock, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full
fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued, as the case may be, would have been at
least 2.25 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or preferred stock had been issued, as the case may
be, at the beginning of such four-quarter period. 
 (b) Notwithstanding the foregoing, Section 10.11(a) will not
prohibit the incurrence of any of the following (the items of Indebtedness described below in this Section 10.11(b) being referred to collectively as “Permitted Debt”): 
 (i) the incurrence by the Company and any Restricted Subsidiary of Indebtedness and letters of credit under Credit Facilities in an
aggregate principal amount 

  

 48 







 
at any one time outstanding under this clause (i) (with letters of credit being deemed to have a principal amount equal to the maximum potential
liability of the Company and its Restricted Subsidiaries thereunder) not to exceed the greater of (x) $1.1 billion and (y) 20% of Adjusted Consolidated Net Tangible Assets, determined as of the date of the incurrence of such Indebtedness
after giving pro forma effect to such incurrence and the application of the proceeds therefrom; 
 (ii) the incurrence by the
Company and its Restricted Subsidiaries of the Existing Indebtedness; 
 (iii) the incurrence by the Company and the
Guarantors of Indebtedness represented by the Notes or the Guarantees of the Notes, to be incurred by the Company or any of the Guarantors on the Issue Date of the Notes; 
 (iv) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations,
mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the
business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant
to this clause (iv), not to exceed $50.0 million at any time outstanding; 
 (v) the incurrence by the Company or any of its
Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance, replace, defease or discharge Indebtedness (other than intercompany Indebtedness) or Disqualified Stock of the
Company, or Indebtedness (other than intercompany Indebtedness) or preferred stock of a Restricted Subsidiary, in each case that was permitted by this Indenture to be incurred or issued under Section 10.11(a) or clause (ii), (iii), (iv),
(v) or (x) of this Section 10.11(b); 
 (vi) the incurrence by the Company or any of its Restricted
Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that (A) any subsequent issuance or transfer of Equity Interests that results in any such
Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (B) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary will be deemed, in each
case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (vi); 
 (vii) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of shares
of preferred stock; provided, however, that: 
 (A) any subsequent issuance or transfer of Equity Interests
that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary; and 
 (B)
any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Restricted Subsidiary, will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not
permitted by this clause (vii); 
  

 49 







 (viii) the incurrence of obligations of the Company or a Restricted Subsidiary pursuant
to Interest Rate and Currency Hedges, in each case entered into in the ordinary course of business for the purpose of limiting risks that arise in the ordinary course of business of the Company and its Restricted Subsidiaries; 
 (ix) the guarantee by the Company or any of the Guarantors of Indebtedness of the Company or a Restricted Subsidiary that was permitted to
be incurred by another provision of this covenant; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the guarantee shall be subordinated or pari passu, as applicable, to the
same extent as the Indebtedness guaranteed; 
 (x) Permitted Acquisition Indebtedness; 
 (xi) the incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from the honoring by a bank or other financial
institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; 
 (xii) Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of
the Company and the Restricted Subsidiaries; 
 (xiii) the incurrence by the Company or any Restricted Subsidiary of
Indebtedness arising from agreements of the Company or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any
business, assets or Capital Stock of a 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; 
 (xiv) the incurrence by the Company or any Restricted Subsidiary of Indebtedness
arising from Guarantees of Indebtedness of joint ventures at any time outstanding not to exceed the greater of $50.0 million and 1.0% of Adjusted Consolidated Net Tangible Assets determined as of the date of incurrence of such Indebtedness after
giving pro forma effect to such incurrence and the application of proceeds thereof; and 
 (xv) the incurrence by the Company
or any of its Restricted Subsidiaries of Indebtedness in an aggregate principal amount (or accreted value, as applicable) that, when taken together with all other Indebtedness of the Company outstanding on the date of such incurrence (other than
Indebtedness permitted by clauses (i) through (xiv) above or Section 10.11(a)) does not exceed the greater of (x) 2.5% of Adjusted Consolidated Net Tangible Assets determined as of the date of incurrence of such Indebtedness and
(y) $125.0 million. 
 (c) For purposes of determining compliance with this Section 10.11, in the event that an item
of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (xv) of Section 10.11(b), or is entitled to be incurred pursuant to Section 10.11(a), the Company
will be permitted to divide and classify such item of Indebtedness on the date of its incurrence, or later divide and reclassify all or a portion of 

  

 50 







 
such item of Indebtedness, in any manner that complies with this Section 10.11. The accrual of interest, the accretion or amortization of original issue
discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on
Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will be deemed not to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant; provided, in each such
case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Company as accrued. 
 (d)
For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness and issuance of preferred stock, 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 10.11, the maximum amount of Indebtedness that the Company may incur pursuant to this Section 10.11 shall not be deemed to be exceeded solely as a result of fluctuations
in the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the
currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing. 
 SECTION 4.06. Asset Sales. 
 Subject to the limitations set forth in the
preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further amended by adding the following Section 10.12 thereto: 
 Section 10.12 Asset Sales. 
 (a) The Company will not, and will not permit any of
its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (i) the Company (or the Restricted Subsidiary, as the case
may be) receives consideration at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and 
 (ii) either (x) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents or (y) the Fair Market Value of all forms
of consideration other than cash and Cash Equivalents received for all Asset Sales since March 13, 2007 does not exceed in the aggregate 10% of the Adjusted Consolidated Net Tangible Assets of the Company at the time each determination is made.
For purposes of this provision, each of the following will be deemed to be cash: 
 (A) any liabilities, as shown on the
Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by
the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability; 
  

 51 







 (B) any securities, notes or other obligations received by the Company or any such
Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days after the date of the Asset Sale, to the extent of the cash received in that conversion; 
 (C) any stock or assets of the kind referred to in clauses (ii) or (iv) of Section 10.12(b) below; and 
 (D) accounts receivable of a business retained by the Company or any Restricted Subsidiary, as the case may be, following the sale of
such business, provided that such accounts receivable (1) are not past due more than 90 days and (2) do not have a payment date greater than 120 days from the date of the invoice creating such accounts receivable. 
 (b) Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the
case may be) may: 
 (i) apply such Net Proceeds to repay Senior Debt; 
 (ii) apply such Net Proceeds to invest in Additional Assets; 
 (iii) apply such Net Proceeds to make capital expenditures in respect of a Related Business of the Company or any of its Restricted
Subsidiaries; or 
 (iv) enter into a bona fide binding contract with a Person other than an Affiliate of the Company to apply
the Net Proceeds pursuant to clauses (ii) or (iii) above, provided that such binding contract shall be treated as a permitted application of the Net Proceeds from the date of such contract until the earlier of: 
 (A) the date on which such acquisition or expenditure is consummated, and 
 (B) the 180th day following the expiration of the aforementioned 360-day period. 
 Any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses (i) through (iv) above will constitute “Excess
Proceeds.” 
 (c) On the 361st day (or upon the failure to close the contract referred to in clause (iv) of
Section 10.12(b) above within the 180 day time period thereafter) after the Asset Sale (or, at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $40.0 million, the Company will make an offer
(the “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets, to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of
the principal amount plus accrued and unpaid interest, to the date of purchase, and will be payable in cash. If any Excess Proceeds 

  

 52 







 
remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If
the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes to be purchased on a pro rata basis. Upon completion of
each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 (d) Notwithstanding the foregoing, the sale,
conveyance or other disposition of all or substantially all of the assets of the Company, or of the Company and its Restricted Subsidiaries, taken as a whole, will be governed by Sections 8.1 and/or 10.15 of this Indenture, as applicable, and not by
this Section 10.12. 
 (e) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or
regulations conflict with the Asset Sale provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of this
Indenture by virtue of such compliance. 
 SECTION 4.07. Transactions with Affiliates. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further
amended by adding the following Section 10.13 thereto: 
 Section 10.13 Transactions with Affiliates. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate of the Company (each, an “Affiliate Transaction”), unless: 
 (i) the Affiliate Transaction is on terms
that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 
 (ii) the Company delivers to the Trustee: 
 (A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, a Board Resolution of the Company set forth in an Officers’
Certificate certifying that such Affiliate Transaction complies with this Section 10.13 and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of the Company; and 

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess
of $40.0 million, an opinion as to the fairness to the Company or such Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. 
  

 53 







 (b) The following items will not be deemed to be Affiliate Transactions and, therefore,
will not be subject to the provisions of the prior paragraph: 
 (i) any employment, consulting or similar agreement or other
compensation, or arrangement, stock option or stock ownership plan, employee benefit plan, officer or director indemnification agreement, restricted stock agreement, severance agreement or other compensation plan or arrangement entered into by the
Company or any of its Restricted Subsidiaries in the ordinary course of business and payments, awards, grants or issuances of securities pursuant thereto; 
 (ii) transactions between or among the Company and/or its Restricted Subsidiaries; 
 (iii)
transactions with a Person that is an Affiliate of the Company solely because the Company owns, directly or through a Subsidiary, an Equity Interest in, or controls, such Person;

 SECTION 4.08. Limitation on Liens. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further
amended by adding the following Section 10.14 thereto: 
 Section 10.14 Limitation on Liens. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or permit to exist
any Lien (other than Permitted Liens) upon any Principal Property or any shares of stock or Indebtedness of any Restricted Subsidiary that owns or leases any Principal Property (whether such Principal Property, shares of stock or Indebtedness are
now owned or hereafter acquired), securing any Subordinated Debt or other Indebtedness, unless: 
 (a) in the case of Liens
securing Subordinated Debt of the Company or a Guarantor, the Notes or Subsidiary Guarantee, as applicable, are secured by a Lien on such Principal Property or such shares of stock or Indebtedness on a senior basis to the Subordinated Debt so
secured with the same priority as the Notes or such Subsidiary Guarantee, as applicable, has to such Subordinated Debt until such time as such Subordinated Debt is no longer so secured by a Lien; and 
 (b) in the case of Liens securing other Indebtedness of the Company or a Guarantor, the Notes or Subsidiary Guarantee, as applicable, are
secured by a Lien on such Principal Property or such shares of stock or Indebtedness on an equal and ratable basis with the other Indebtedness so secured until such time as such other Indebtedness is no longer so secured by a Lien. 
 SECTION 4.09. Offer to Repurchase upon a Change of Control. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further
amended by adding the following Section 10.15 thereto: 
 Section 10.15 Offer to Repurchase upon a Change of Control.

 (a) If a Change of Control Triggering Event occurs, each Holder of Notes will have the right to require the Company to
repurchase all or any part (equal to $1,000 or an integral multiple thereof) of that Holder’s Notes pursuant to an offer (“Change of Control Offer”) on the terms set forth in this Indenture. In the Change of Control Offer, the Company
will offer a payment in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest on the Notes repurchased to the date of purchase (the “Change of
Control Payment Date”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control Triggering Event, the Company will mail
a notice to each Holder of Notes describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Notes on the Change of Control Payment Date specified in the notice, which date will be no
earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures described in Article Fifteen of this Indenture (including the notice required thereby) and described in such notice. The Company will
comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change
of Control Triggering 

  

 55 







 
Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of this
Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of this Indenture by virtue of such compliance.

 (b) On the Change of Control Payment Date, the Company will, to the extent lawful: 
 (i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 
 (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly
tendered; and 
 (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an
Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 (c) The Paying Agent will promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment through the facilities of the Depositary), and
the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will
be in a principal amount of $1,000 or an integral multiple thereof. Any Note so accepted for payment will cease to accrue interest on and after the Change of Control Payment Date unless the Company defaults in making the Change of Control Payment.

 (d) The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date. 
 (e) Notwithstanding anything to the contrary in this Section 10.15, the Company will
not be required to make a Change of Control Offer upon a Change of Control Triggering Event if (i) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this
Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (ii) notice of redemption with respect to the Notes has been given pursuant
to this Indenture, unless and until there is a default in payment of the applicable Redemption Price. 
 (f) A Change of
Control Offer may be made in advance of a Change of Control, and conditioned upon the occurrence of such Change of Control, if a definitive agreement is in place for a Change of Control at the time of making the Change of Control Offer. Notes
repurchased by the Company pursuant to a Change of Control Offer will have the status of Notes issued but not Outstanding or will be retired and cancelled, at the Company’s option. Notes purchased by a third party pursuant to clause (e) of
this Section 10.15 will have the status of Notes issued and Outstanding. 
 (g) In the event that Holders of at least 90%
of the aggregate principal amount of the Outstanding Notes accept a Change of Control Offer and the Company purchases all of the Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior
notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the Notes that remain Outstanding following such purchase at a Redemption Price equal to the Change of Control
Payment plus, to the extent not 

  

 56 







 
included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain Outstanding, to the date of redemption (subject to the right
of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date). 
 SECTION 4.10.
Designation of Restricted and Unrestricted Subsidiaries. 
 Subject to the limitations set forth in the preamble to
ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further amended by adding the following Section 10.16 thereto: 
 Section 10.16 Designation of Restricted and Unrestricted Subsidiaries. 
 (a) The
Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair
Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount
available for Restricted Payments under Section 10.9 of this Indenture or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be
permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 
 (b)
Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a Board Resolution of the Company giving effect to such designation and an Officers’
Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 10.9. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it
will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be
incurred as of such date under Section 10.11, the Company will be in Default of such covenant. The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such
designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (i) such Indebtedness is permitted under
Section 10.11, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period; and (ii) no Default or Event of Default would be in existence following such designation. 

SECTION 4.11. Future Guarantors. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further amended by adding the following Section 10.17 thereto:

 Section 10.17 Future Guarantors. 
 If any Domestic Restricted Subsidiary that is not a Guarantor is or becomes obligated under any Indebtedness pursuant to a Guarantee of Indebtedness of the Company or any Guarantor (other than the Notes), and the
maximum principal amount of Indebtedness of such Domestic Restricted Subsidiary under such Guarantee exceeds $10.0 million, then the Company shall cause that Domestic Restricted Subsidiary to Guarantee the Notes and become a Guarantor, 

  

 57 







 
pursuant to the Subsidiary Guarantee provisions of this Indenture, by executing a supplemental indenture and delivering it to the Trustee within 30 days
after the date on which such Domestic Restricted Subsidiary Guaranteed such Indebtedness of the Company or a Guarantor; provided, however, that the Company shall not be required to cause such Domestic Restricted Subsidiary to so
Guarantee the Notes and become a Guarantor prior to the 180th day after the consummation of any transaction (including without limitation any merger, consolidation or purchase) pursuant to which such Domestic Restricted Subsidiary becomes a
Subsidiary of the Company. 
 SECTION 4.12. Covenant Termination. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further
amended by adding the following Section 10.18 thereto: 
 Section 10.18 Covenant Termination. 
 Notwithstanding any provision of this Indenture or of the Notes to the contrary, from and after the occurrence of an Investment Grade
Rating Event, the Company and its Restricted Subsidiaries will cease to be subject to Sections 10.9, 10.10, 10.11, 10.12, 10.13, 10.15 and 10.16 and 8.1(a)(iv) of this Indenture and no Default or Event of Default shall result from any failure to
comply with any of the provisions of such Sections.

the principal sum of                                  United States Dollars on

September 1, 2009, at the rate of 10% per annum, until the principal hereof is paid or made available for payment; provided, however, that upon any failure by the Company for 60 days to comply with Section 10.7 of such
Indenture, the interest rate on the Securities of this series will increase by 50 basis points (0.5%) and remain at such increased rate thereafter but only for so long as there is a Default under such Section 10.7, and upon resumption of
compliance by the Company with such Section 10.7, the interest rate on the Securities of this series will be reset at the initial rate applicable on the Issue Date. Interest on overdue principal and interest on overdue interest, if any, will

 [FORM OF REVERSE OF NOTE] 
 PLAINS EXPLORATION & PRODUCTION COMPANY 
 10% Senior Notes due 2016

 This Security is one of a duly authorized issue of senior securities of the Company (herein called the “Securities”), issued
and to be issued in one or more series under an Indenture, dated as of March 13, 2007 (the “Original Indenture”), between the Company and Wells Fargo Bank, N.A., as Trustee (herein called the “Trustee”, which term includes
any successor trustee under the Indenture), as amended and supplemented by the Ninth Supplemental Indenture thereto dated as of March 6, 2009 (the “Supplemental Indenture”), by and among the Company, the Trustee and the Guarantors
named therein (such Original Indenture, as so amended and supplemented being herein called the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement, of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. As provided in the
Indenture, the Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest, if any, at different rates, may be subject to different
redemption provisions, if any, may be subject to different sinking, purchase or analogous funds, if any, may be subject to different covenants and Events of Default and may otherwise vary as in the Indenture provided or permitted. This Security is
one of the series designated on the face hereof. 
 This security is the general, unsecured, senior obligation of the Company and is
guaranteed pursuant to a guarantee (the “Subsidiary Guarantee”) by each of the persons named as Guarantors in the Supplemental Indenture (the “Guarantors”). The Subsidiary Guarantee is the general, unsecured, senior obligation of
each Guarantor. 
 Except as described below, and except as provided in Section 10.15(g) of the Indenture, the Securities of this series
are not redeemable until March 1, 2013. On and after March 1, 2013, the Company may redeem all or a part of the Securities of this series, from time to time upon not less than 30 nor more than 60 days’ notice, at the following
Redemption Prices (expressed as a percentage of principal amount) plus accrued and unpaid interest on the Securities of this series to be redeemed to the applicable 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 beginning on March 1 of the years indicated below: 
  

				
	 Year
	  	Redemption Price	 
	 2013
	  	105.000	%
	 2014
	  	102.500	%
	 2015 and thereafter
	  	100.000	%

 The Securities of this series will also be redeemable, in whole or in part, at the Company’s
option at any time or from time to time, prior to March 1, 2013, at the applicable Make-Whole Price (as defined below), in accordance with the provisions of the Indenture. 
 “Make-Whole Price” with respect to any Securities of this series to be redeemed, means an amount equal to the greater of: 
 (1) 100% of the principal amount of such Securities; and 
 (2) the sum of the present values of (a) the Redemption Price of such Securities at March 1, 2013 (as set forth above) and
(b) the remaining scheduled payments of interest from the Redemption Date to March 1, 2013 (not including any portion of such payments of interest accrued as of the Redemption Date) discounted back to the Redemption Date on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 50 basis points; 
 plus, in
the case of both (1) and (2), accrued and unpaid interest on such Securities to the Redemption Date. Unless the Company defaults in payment of the Make-Whole Price, on and after the applicable Redemption Date, interest will cease to accrue on
the Securities of this series to be redeemed. 
  

 A-3 







 “Comparable Treasury Issue” means, with respect to Securities of this series to be
redeemed, the U.S. Treasury security selected by an Independent Investment Banker as having a maturity most nearly equal to the period from the Redemption Date to March 1, 2013, at the time of selection and in accordance with customary
financial practice, in pricing new issues of corporate debt securities; provided if such period is less than one year, then the U.S. Treasury security having a maturity of one year shall be used. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of four Reference Treasury Dealer
Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such Reference
Treasury Dealer Quotations. 
 “Independent Investment Banker” means J.P. Morgan Securities Inc. or Banc of America
Securities LLC and their respective successors, at the Company’s option, or, if such firms or the successors, if any, to such firms, as the case may be, are unwilling or unable to select the Comparable Treasury Issue, an independent investment
banking institution of national standing appointed by the Company. 
 “Reference Treasury Dealer” means J.P. Morgan
Securities Inc. or Banc of America Securities LLC, at the Company’s option, and three additional primary U.S. government securities dealers in New York City (each a “Primary Treasury Dealer”) selected by the Company, and their
respective successors (provided, however, that if any such firm or any such successor, as the case may be, shall cease to be a primary U.S. government securities dealer in New York City, the Company shall substitute therefor another
Primary Treasury Dealer). 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer
and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference
Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 
 “Treasury
Rate” means, with respect to any Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated
“H.15(159)” or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the
caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the stated maturity, yields for the two published maturities most closely
corresponding to the Comparable Treasury Issue shall be determined, and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month) or (2) if such release (or any successor
release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date. 

The notice of redemption with respect to the foregoing redemption need not set forth the Make-Whole Price but only the manner of calculation thereof.
The Company will notify the Trustee of the Make-Whole Price with respect to any redemption promptly after the calculation, and the Trustee shall not be responsible for such calculation.
