 INDENTURE, dated as of December 1, 2005, among Chaparral Energy, Inc., a Delaware corporation (the
“Issuer”), the Guarantors (as defined) and Wells Fargo Bank, National Association, as Trustee (the “Trustee”). 
  
 The Issuer has duly authorized the creation of an issue of 8  1/2 % Senior Notes due 2015 (the “Notes”) and, to provide therefor, the Issuer and the Guarantors have duly authorized the execution and delivery of this Indenture. All things necessary
to make the Notes, when duly issued and executed by the Issuer, and authenticated and delivered under this Indenture, the valid obligations of the Issuer, and to make this Indenture a valid and binding agreement of the Issuer, have been done.

  
 Each party hereto agrees as follows for the benefit of
the other party and for the equal and ratable benefit of the Holders of the Notes. 
  
 ARTICLE I. 
  
 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 or is merged with and into 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 or is merged with and into 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 properties or
assets to be used by the Issuer or a Restricted Subsidiary in the Oil and Gas Business; 
  
 (2) capital expenditures by the Issuer 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 Issuer 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. 
  
 “Additional Notes” means Notes, in addition to, and having identical terms (except for a date of original issuance different than the Issue Date) as, the $325,000,000 aggregate principal amount of
Notes issued on the Issue Date, issued pursuant to Article II and in compliance with Section 4.12. 
  
 “Adjusted Consolidated Net Tangible Assets” of a Person means (without duplication), as of the date of determination, the remainder of:

  
 (a) the sum of: 
  
 (i) discounted future net revenues from proved oil and gas
reserves of such Person and its Restricted Subsidiaries calculated in accordance with SEC guidelines before any state or federal income taxes, as estimated by the Issuer in a reserve report prepared as of the end of the Issuer’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 
  
 (A) estimated proved oil and gas reserves acquired since such year end, which reserves were not reflected
in such year end reserve report, and 
  
 (B)
estimated oil and gas reserves attributable to extensions, discoveries and other additions and upward revisions of estimates of proved oil and gas reserves (including previously estimated development costs Incurred during the period and the
accretion of discount since the prior period end) since such year end due to exploration, development or exploitation, production or other activities which would, in accordance with standard industry practice, cause such revisions, in each case
calculated in accordance with SEC 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 
  
 (C) estimated proved oil and gas reserves produced or
disposed of since such year end, and 
  

 -2- 









 (D) 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 SEC guidelines (utilizing the prices for the fiscal quarter ending prior to the date of determination), 
  
 provided, however, that in the case of each of the determinations made pursuant to clauses (A) through (D), such increases and decreases shall
be as estimated by the Issuer’s petroleum engineers; 
  
 (ii) the capitalized costs that are attributable to oil and gas properties of such Person and its Restricted Subsidiaries to which no proved oil and gas reserves are attributable, based on such Person’s books and
records as of a date no earlier than the date of such Person’s latest available annual or quarterly financial statements; 
  
 (iii) the Net Working Capital of such Person on a date no earlier than the date of such Person’s latest annual or quarterly financial
statements; and 
  
 (iv) the greater of

  
 (A) the net book value of other tangible
assets of such Person and its Restricted Subsidiaries, as of a date no earlier than the date of such Person’s latest annual or quarterly financial statement, and 
  
 (B) the appraised value, as estimated by independent appraisers, of other tangible assets of such Person
and its Restricted Subsidiaries, as of a date no earlier than the date of such Person’s latest audited financial statements; 
  
 minus 
  
 (b) the sum of: 
  
 (i) Minority Interests; 
  
 (ii) any net gas balancing liabilities of such Person and its Restricted Subsidiaries reflected in such Person’s latest audited
balance sheet; 
  
 (iii) to the extent included
in (a)(i) above, the discounted future net revenues, calculated in accordance with SEC guidelines (utilizing the prices 

  

 -3- 









 
utilized in such Person’s year end reserve report), attributable to reserves which are required to be delivered to third parties to fully satisfy the
obligations of the Issuer and its Restricted Subsidiaries with respect to Volumetric Production Payments (determined, if applicable, using the schedules specified with respect thereto); and 
  
 (iv) the discounted future net revenues, calculated in
accordance with SEC 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
(a)(i) above, would be necessary to fully satisfy the payment obligations of such Person and its Subsidiaries with respect to Dollar-Denominated Production Payments (determined, if applicable, using the schedules specified with respect thereto).

  
 If the Issuer changes its method of accounting from the full
cost method of accounting to the successful efforts or a similar method, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if the Issuer were still using the full cost method of accounting. 
  
 “Affiliate” of any specified Person means any other Person
directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person. For the purposes of this definition, “control” when used with respect to any Person means the power to direct the
management and policies of such Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the
foregoing; provided that beneficial ownership of 10% or more of the Voting Stock of a Person shall be deemed to be control. 
  
 “Affiliate Transaction” has the meaning provided in Section 4.11. 
  
 “Agent” means any Registrar, Paying Agent or co-Registrar. 
  
 “Applicable Premium” means, with respect to any Note on any
applicable redemption date, the greater of: 
  
 (1) 1.0% of the principal amount of such Note; and 
  
 (2) the excess, if any, of: 
  
 (a) the present value at such redemption date of (i) the redemption price of such Note at December 1, 2010 (such redemption price being set forth in the table appearing in Section 3.3) plus (ii) all required interest
payments (excluding accrued and unpaid interest 

  

 -4- 









 
to such redemption date) due on such Note through December 1, 2010, computed using a discount rate equal to the Treasury Rate as of such redemption date
plus 50 basis points; over (b) the principal amount of such Note. 
  
 “Applicable Procedures” means, with respect to any transfer or exchange of or for beneficial interests in any Global Note, the rules and procedures of the Depository, Euroclear and/or Clearstream that apply to such transfer
or exchange. 
  
 “Asset Disposition” means any
direct or indirect sale, lease (other than an operating lease entered into in the ordinary course of the Oil and Gas Business), transfer, issuance or other disposition, or a series of related sales, leases, transfers, issuances or dispositions that
are part of a common plan, of (A) shares of Capital Stock of a Restricted Subsidiary (other than directors’ qualifying shares or shares required by applicable law to be held by a Person other than the Issuer or a Restricted Subsidiary),
(B) all or substantially all the assets of any division or line of business of the Issuer or any Restricted Subsidiary, or (C) any other assets of the Issuer or any Restricted Subsidiary outside of the ordinary course of business of the
Issuer or such Restricted Subsidiary (each referred to for the purposes of this definition as a “disposition”), in each case by the Issuer or any of its Restricted Subsidiaries, including any disposition by means of a merger, consolidation
or similar transaction.

(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 EBITDA and Consolidated Interest Expense for such period

 (2) if, since the beginning of such period, the Issuer or any Restricted Subsidiary will have made any Asset
Disposition or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is such an Asset Disposition, the Consolidated EBITDA for such period will be reduced by an amount equal to the Consolidated EBITDA (if positive)

clause (2) or (3) above if made by the Issuer or a Restricted Subsidiary during such period, Consolidated EBITDA 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 Issuer (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 average rate in effect from the beginning of such period to the date of determination had been the applicable rate
for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement is less than 12 months, then such Interest Rate Agreement shall only be taken into
account for that portion of the period equal to the remaining term thereof). If any Indebtedness that is being given pro forma effect bears an interest rate at the option of the Issuer, the interest rate shall be calculated by applying such optional
rate chosen by the Issuer. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon
the rate actually chosen, or, if none, then based upon such optional rate chosen as the Issuer may designate.

 At
least one Officer shall execute the Notes for the Issuer by manual or facsimile signature. 
  
 If an Officer whose signature is on a Note or a Subsidiary Guarantee was an Officer at the time of such execution but no longer holds that office or position at the time the Trustee authenticates the Note, the Note

Each such written order shall specify the amount of Notes to be authenticated and the date on which the Notes are to be authenticated, whether the Notes are to be Notes or Additional Notes and whether the Notes are to be issued as Definitive Notes
or Global Notes or such other information as the Trustee may reasonably request. Any Additional Notes shall be part of the same issue as the Notes being issued on the Issue Date and will vote on all matters as one class with the Notes being issued
on the Issue Date, including, without limitation, waivers, amendments, redemptions, Change of Control Offers and Asset Disposition Offers. For the purposes of this Indenture, except for Section 4.12, references to the Notes include Additional

 The Trustee may appoint an
authenticating agent (the “Authenticating Agent”) reasonably acceptable to the Issuer to authenticate Notes. Unless otherwise provided in the appointment, an Authenticating Agent may authenticate Notes whenever the Trustee may do
so. Each reference in this Indenture to authentication by the Trustee includes authentication by such Authenticating Agent. An Authenticating Agent has the same rights as an Agent to deal with the Issuer or with any Affiliate of the Issuer.

exchange. The Issuer, upon prior written notice to the Trustee, may have one or more co-Registrars and one or more additional paying agents reasonably acceptable to the Trustee. The term “Paying Agent” includes any additional Paying Agent.
The Issuer may act as Paying Agent, except that, for the purposes of payments on the Notes pursuant to Sections 4.15 and 4.16, neither the Issuer nor any Affiliate of the Issuer may act as Paying Agent. 
  
 The Issuer shall enter into an appropriate agency agreement with any Agent
not a party to this Indenture, which agreement shall incorporate the provisions of the TIA and implement the provisions of this Indenture that relate to such Agent. The Issuer shall notify the Trustee, in advance, of the name and address of any such
Agent. If the Issuer fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such. 
  
 The Issuer initially appoints the Trustee as Registrar, Paying Agent and agent for service of demands and notices in connection with the Notes, until such
time as the Trustee has resigned or a successor has been appointed. Any of the Registrar, the Paying Agent or any other agent may resign upon 30 days’ prior written notice to the Issuer. 
  
 SECTION 2.4. Paying Agent To Hold Assets in Trust.

  
 The Issuer 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 the Holders or the Trustee all assets held by the Paying Agent for the payment of principal of, premium or Liquidated 

  

 -49- 









 
Damages, if any, or interest on, the Notes (whether such assets have been distributed to it by the Issuer or any other obligor on the Notes), and the Issuer
and the Paying Agent shall notify the Trustee of any Default by the Issuer (or any other obligor on the Notes) in making any such payment. The Issuer at any time may require a Paying Agent to distribute all assets held by it to the Trustee and
account for any assets disbursed and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to distribute all assets held by it to the Trustee and to account for
any assets distributed. If the Issuer acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all assets held by it as Paying Agent. Upon distribution to the Trustee of all assets that shall have
been delivered by the Issuer to the Paying Agent, the Paying Agent (if other than the Issuer) shall have no further liability for such assets. 
  
 SECTION 2.5. Holder 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 the
Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Issuer shall furnish or cause the Registrar to furnish to the Trustee before each Record Date and at such other times as the Trustee may request
in writing a list as of such date and in such form as the Trustee may reasonably require of the names and addresses of the Holders, which list may be conclusively relied upon by the Trustee.

 (ii) Restricted Definitive Notes to Unrestricted Definitive Notes. Any Restricted Definitive Note
may be exchanged by the Holder thereof for an Unrestricted Definitive Note or transferred to a Person or Persons who take delivery thereof in the form of an Unrestricted Definitive Note if: 
  
 (A) such exchange or transfer is effected pursuant to the
Exchange Offer in accordance with the Registration Rights Agreement and the Holder, in the case of an exchange, or the transferee, in the case of a transfer, certifies in the applicable letter of transmittal that it is not (1) a Broker-Dealer,
(2) a Person participating in the distribution of the Exchange Notes or (3) a Person who is an affiliate (as defined in Rule 144) of the Issuer;

to maintain compliance with the Securities Act.

Unrestricted Definitive Notes to Unrestricted Definitive Notes. A Holder of Unrestricted Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of an Unrestricted Definitive Note. Upon receipt of a request
to 

  

 -60- 









 
register such a transfer, the Registrar shall register the Unrestricted Definitive Notes pursuant to the instructions from the Holder thereof. 
  
 (f) Exchange Offer. Upon the occurrence of the Exchange Offer in
accordance with the Registration Rights Agreement, the Issuer will issue and, upon receipt of an Authentication Order in accordance with Section 2.2 hereof, the Trustee will authenticate: 
  
 (i) one or more Unrestricted Global Notes in an aggregate principal amount
equal to the principal amount of the beneficial interests in the Restricted Global Notes accepted for exchange in the Exchange Offer by Persons that certify that (A) they are not Broker-Dealers, (B) they are not participating in a
distribution of the Exchange Notes and (C) they are not affiliates (as defined in Rule 144) of the Issuer; and 
  
 (ii) Unrestricted Definitive Notes in an aggregate principal amount equal to the principal amount of the Restricted Definitive Notes accepted for exchange
in the Exchange Offer by Persons that certify that (A) they are not Broker-Dealers, (B) they are not participating in a distribution of the Exchange Notes and (C) they are not affiliates (as defined in Rule 144) of the Issuer.

  
 Concurrently with the issuance of such Notes, the Trustee will cause the

Unrestricted Definitive Notes in the appropriate principal amount. 
  
 (g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled
in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is
exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly
and an endorsement shall be made on such Global Note by the Trustee or by the Depository at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take
delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depository at the direction of the
Trustee to reflect such increase.

 (h) General Provisions Relating to Transfers and Exchanges. 
  
 (i) To permit registrations of transfers and exchanges, the Issuer shall
execute and the Trustee shall authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.2 hereof or at the Registrar’s request. 
  
 (ii) No service charge shall be made to a holder of a beneficial interest in
a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other
than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.7, 2.10, 3.7, 4.15, 4.16 and 9.5 hereof). 
  

(iii) Neither the Registrar nor the Issuer shall be required to register the transfer of or exchange any Note selected for redemption in whole or in
part, except the unredeemed portion of any Note being redeemed in part. 
  
 (iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits
under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
  
 (v) The Issuer shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of
business 15 days before the day of any selection of Notes for redemption under Section 3.2 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for
redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between a Record Date and the next succeeding Interest Payment Date. 
  
 (vi) Prior to due presentment for the registration of a transfer of any Note,
the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of (and premium, if any), Liquidated Damages, if any, and
interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Issuer shall be affected by notice to the contrary. 
  
 (vii) Upon surrender for registration of transfer of any Note at the office or agency of the Issuer designated pursuant to Section 4.2 hereof, the
Issuer shall execute, and the Trustee shall authenticate and mail, in the name of the designated transferee or transferees, one or more replacement Notes of any authorized denomination or denominations of a like aggregate principal amount.

  

 -62- 









 (viii) At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination
or denominations of a like aggregate principal amount upon surrender of the Notes to be exchanged at such office or agency. Whenever any Global Notes or Definitive Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee
shall authenticate and mail, the replacement Global Notes and Definitive Notes which the Holder making the exchange is entitled to in accordance with the provisions of Section 2.2 hereof. 
  
 (ix) All certifications, certificates and Opinions of Counsel required to be
submitted to the Registrar pursuant to this Section 2.6 to effect a registration of transfer or exchange may be submitted by facsimile. 
  
 SECTION 2.7. Replacement Notes. 
  
 If a mutilated Note is surrendered to the Trustee or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Issuer
shall issue and the Trustee shall authenticate a replacement Note and the Subsidiary Guarantors shall execute a Subsidiary Guarantee thereon if the Trustee’s requirements are met. If required by the Trustee or the Issuer, such Holder must
provide an indemnity bond or other indemnity of reasonable tenor, sufficient in the reasonable judgment of the Issuer, the Subsidiary Guarantors and the Trustee, to protect the Issuer, the Subsidiary Guarantors, the Trustee or any Agent from any
loss which any of them may suffer if a Note is replaced. Every replacement Note shall constitute an additional obligation of the Issuer and the Subsidiary Guarantors. 
  
 SECTION 2.8. Outstanding Notes. 
  
 Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those canceled by it,
those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof and those described in this Section as not outstanding. Subject to the provisions of
Section 2.9, a Note does not cease to be outstanding because the Issuer or any of its Affiliates holds the Note. 
  
 If a Note is replaced pursuant to Section 2.7 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the
Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser for value. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.7.

  
 If on a Redemption Date or the Maturity Date the Paying Agent
(other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the principal, premium, if any, and interest due on the Notes payable on that date and is not
prohibited from paying such money to the Holders 

  

 -63- 









 
thereof pursuant to the terms of this Indenture, then on and after that date such Notes shall be deemed not to be outstanding and interest on them shall
cease to accrue. 
  
 SECTION 2.9. Treasury
Notes. 
  
 In determining whether the Holders of the
required principal amount of Notes have concurred in any direction, waiver, consent or notice, Notes owned by the Issuer or any Guarantor or an Affiliate of the Issuer or any Guarantor shall be considered as though they are not outstanding, except
that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so considered. The Issuer shall
notify the Trustee, in writing, when, to its knowledge, any of its Affiliates repurchase or otherwise acquire Notes, of the aggregate principal amount of such Notes so repurchased or otherwise acquired and such other information as the Trustee may
reasonably request and the Trustee shall be entitled to rely thereon. 
  
 SECTION 2.10. Temporary Notes. 
  
 Until definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes upon receipt of a written order of the Issuer in the form of an Officers’ Certificate. The Officers’
Certificate shall specify the amount of temporary Notes to be authenticated and the date on which the temporary Notes are to be authenticated. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the
Issuer considers appropriate for temporary Notes and so indicate in the Officers’ Certificate. Without unreasonable delay, the Issuer shall prepare, the Trustee shall authenticate and the Subsidiary Guarantors shall execute Subsidiary
Guarantees on, upon receipt of a written order of the Issuer pursuant to Section 2.2, definitive Notes in exchange for temporary Notes. 
  
 SECTION 2.11. Cancellation. 
  
 The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes
surrendered to them for transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall cancel and, at the written direction of the Issuer, shall dispose, in its customary
manner, of all Notes surrendered for transfer, exchange, payment or cancellation. The Trustee shall maintain a record of all canceled Notes. Subject to Section 2.7, the Issuer may not issue new Notes to replace Notes that they have paid or
delivered to the Trustee for cancellation. If either Issuer shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to
the Trustee for cancellation pursuant to this Section 2.11. 
  

 -64- 









 SECTION 2.12. Defaulted Interest. 
  
 The Issuer will pay interest on overdue principal from time to time on demand
at a rate of 0.5 percentage points per annum in excess of the rate of interest then borne by the Notes. The Issuer shall, to the extent lawful, pay interest on overdue installments of interest (without regard to any applicable grace periods) from
time to time on demand at a rate of 0.5 percentage points per annum in excess of the rate of interest then borne by the Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months, and, in the case of a partial
month, the actual number of days elapsed. 
  
 If the Issuer
defaults in a payment of interest on the Notes, it shall pay the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which special record
date shall be the fifteenth day next preceding the date fixed by the Issuer for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. The Issuer shall notify the Trustee in writing of the amount of
defaulted interest proposed to be paid on each Note and the date of the proposed payment (a “Default Interest Payment Date”), and at the same time the Issuer 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 on or 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 provided in this Section; provided, however, that in no event shall the Issuer deposit monies proposed to be paid in respect of defaulted interest later than 11:00 a.m. New York
City time of the proposed Default Interest Payment Date. At least 15 days before the subsequent special record date, the Issuer shall mail (or cause to be mailed) to each Holder, as of a recent date selected by the Issuer, with a copy to the
Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid. Notwithstanding the foregoing, (a) any interest which
is paid prior to the expiration of the 30-day period set forth in Section 6.1(1) shall be paid to Holders as of the regular record date for the Interest Payment Date for which interest has not been paid, and (b) the Issuer may make payment
of any defaulted interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange. 
  
 SECTION 2.13. CUSIP Number. 
  
 The Issuer in issuing the Notes may use a “CUSIP” number, and, if
so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided, however, that no representation is hereby deemed to be made by the Trustee as to the correctness or accuracy of the
CUSIP number printed in the notice or on the 

  

 -65- 









 
Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify the Trustee of any
change in the CUSIP number. 
  
 SECTION 2.14. Deposit of
Monies. 
  
 Prior to 11:00 a.m. New York City time on
each Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Asset Disposition Purchase Date, the Issuer shall have deposited with the Paying Agent in immediately available funds money sufficient to make cash
payments, if any, due on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Asset Disposition Purchase Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the
Holders on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Asset Disposition Purchase Date, as the case may be. 
  

SECTION 2.15. Restrictive Legends. 
  
 (a) Legends. The following legends shall appear on the face of all Global Notes and Definitive Notes issued under this Indenture unless

 In connection with a redemption pursuant to Section 3.3, at least 30 days but not more than 60 days before a Redemption Date, the Issuer shall mail or cause to be mailed a notice of redemption by first class
mail to each Holder of Notes to be redeemed at its registered address, with a copy to the Trustee and any Paying Agent. At the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s

Once notice of redemption is mailed in accordance with Section 3.4, such notice of redemption shall be irrevocable and Notes called for redemption
shall become due and payable on the Redemption Date and at the Redemption Price plus unpaid accrued interest and Liquidated Damages, if any, as of such date, if any. Upon surrender to the Trustee or Paying Agent, such Notes called for redemption
shall be paid at the Redemption Price plus unpaid accrued interest and Liquidated Damages thereon to the Redemption Date, but installments of interest, the maturity of which is on or prior to the Redemption Date, shall be payable to Holders of
record at the close of business on the relevant Record Dates referred to in the Notes. Interest shall accrue on or after the Redemption Date and shall be payable only if the Issuer defaults in payment of the Redemption Price. 
  
 SECTION 3.6. Deposit of Redemption Price. 
  
 On or before the Redemption Date and in accordance with Section 2.14,
the Issuer shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay the Redemption Price plus unpaid accrued interest and Liquidated Damages, if any, of all Notes to be redeemed on that date. The Paying Agent shall promptly return to

 Unless the Issuer fails to comply with the preceding paragraph and defaults in the payment of such Redemption Price plus
unpaid accrued interest, if any, interest on the Notes to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not such Notes are presented for payment.

within the time periods specified therein with respect to a non-accelerated filer. In the event that the Issuer is not permitted to file such reports, documents and information with the SEC pursuant to the Exchange Act, the Issuer will nevertheless
make available such Exchange Act information to the Trustee and the Holders without cost to any Holder as if the Issuer were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act within the time periods specified
therein with respect to a non-accelerated filer.

Guarantors have agreed that they will make available to the Holders and to prospective investors, upon the request of such Holders, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes
are not freely transferable under the Securities Act to the extent not satisfied by the foregoing. For purposes of this Section 4.8, the Issuer and the Subsidiary Guarantors will be deemed to have furnished the reports to the Trustee and the
holders of Notes as required by this Section 4.8 if it has filed such reports with the SEC via the EDGAR filing system and such reports are publicly available. 
  
 (d) Notwithstanding the foregoing, such requirements shall be deemed satisfied prior to the commencement of the Exchange
Offer or the effectiveness of the Shelf Registration Statement by the filing with the SEC of the Exchange Offer Registration Statement and/or Shelf Registration Statement, and any amendments thereto, with such financial information that satisfies

any usury law or other law that would prohibit or forgive the Issuer from paying all or any portion of the principal of or 

  

 -76- 









 
interest or Liquidated Damages, if any, on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) the Issuer and each of the Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it 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.

Restricted Subsidiary and if such Restricted Subsidiary is not a Wholly-Owned Subsidiary, to minority stockholders (or owners of an equivalent interest in the case of a Subsidiary that is an entity other than a corporation) so long as the Issuer or

other Restricted Payments declared or made subsequent to the Issue Date would exceed the sum of:

determined as set forth in the last sentence of the definition of “Investment.” Such designation will be permitted only if a Restricted Payment in such amount would be permitted at such time, whether pursuant to the first paragraph of this
Section 4.10 or under clause (11) of the second paragraph of this Section 4.10, or pursuant to the definition of “Permitted Investments,” and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

amend or conduct any transaction (including making a payment to, the purchase, sale, lease or exchange of any property or the rendering of any service), contract, agreement or understanding with or for the benefit of any Affiliate of the Issuer (an
“Affiliate Transaction”) unless: 
  
 (1) the terms of such Affiliate Transaction are no less favorable to the Issuer 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; 
  
 (2) if 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 Issuer 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

received a written opinion from an independent investment banking, accounting or appraisal firm of nationally recognized standing that such Affiliate Transaction is fair, from a financial standpoint, to the Issuer or such Restricted Subsidiary or is
not materially less favorable than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate. 
  
 The preceding paragraph will not apply to: 
  
 (1) any Restricted Payment permitted to be made pursuant to
Section 4.10;

or a Restricted Subsidiary for the benefit of the Issuer or a Restricted Subsidiary, as the case may be, permitted under Section 4.12; 
  
 (5) any transaction with a joint venture or similar entity which would constitute an Affiliate Transaction solely because the Issuer or a
Restricted Subsidiary owns, directly or indirectly, an equity interest in or otherwise controls such joint venture or similar entity; 
  
 (6) the issuance or sale of any Capital Stock (other than Disqualified Stock) of the Issuer or the receipt by the Issuer of any capital
contribution from its shareholders; 
  
 (7)

modified, supplemented, extended or renewed from time to time; provided, however, that any future amendment, modification, supplement, extension or renewal 

  

 -84- 









 
entered into after the Issue Date will be permitted to the extent that its terms are not materially more disadvantageous, taken as a whole, to the holders of
the Notes than the terms of the agreements in effect on the Issue Date; and 
  
 (10) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which
are fair to the Issuer and its Restricted Subsidiaries, in the reasonable determination of the board of directors of the Issuer or the senior management thereof, or are on terms at least as favorable as might reasonably have been obtained at such
time from an unaffiliated party.

Subsidiaries to issue Preferred Stock; provided, however, that the Issuer may Incur Indebtedness and any of the Subsidiary Guarantors may Incur Indebtedness and issue Preferred Stock if on the date thereof: 
  
 (1) the Consolidated Coverage Ratio for the Issuer and its
Restricted Subsidiaries is at least 2.00 to 1.00, determined on a pro forma basis (including a pro forma application of proceeds); and 
  
 (2) no Default will have occurred or be continuing or would occur as a consequence of Incurring the Indebtedness or transactions relating
to such Incurrence.

Section 4.12 will not prohibit the Incurrence of the following Indebtedness: 
  
 (1) Indebtedness of the Issuer Incurred pursuant to one or more Credit Facilities in an aggregate amount not to exceed the greater of
(a) $200.0 million less the aggregate amount of all permanent principal repayments since the Issue Date under a Credit Facility that are made under clause 3(a) of the first paragraph of Section 4.16, or (b) 30% of Adjusted
Consolidated Net Tangible Assets determined as of the date of the Incurrence of such Indebtedness after giving effect to the application of the proceeds therefrom, in each case outstanding at any one time; 
  
 (2) Guarantees by the Issuer or Subsidiary Guarantors of
Indebtedness of the Issuer or a Subsidiary Guarantor, as the case may be, 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 Notes 

  

 -85- 









 
or the Subsidiary Guarantee to at least the same extent as the Indebtedness being Guaranteed, as the case may be; 
  
 (3) Indebtedness of the Issuer owing to and held by any
Restricted Subsidiary or Indebtedness of a Restricted Subsidiary owing to and held by the Issuer or any Restricted Subsidiary; provided, however, that (i) any subsequent issuance or transfer of Capital Stock or any other event which
results in any such Indebtedness being held by a Person other than the Issuer or a Restricted Subsidiary of the Issuer and (ii) any sale or other transfer of any such Indebtedness to a Person other than the Issuer or a Restricted Subsidiary of
the Issuer shall be deemed, in each case, to constitute an Incurrence of such Indebtedness by the Issuer or such Subsidiary, as the case may be; 
  
 (4) Indebtedness represented by (a) the Notes issued on the Issue Date, and the related exchange notes issued in a registered
exchange offer (or shelf registration) pursuant to the Registration Rights Agreement, and all Subsidiary Guarantees, (b) any Indebtedness (other than the Indebtedness described in clauses (1), (2) and 4(a)) 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 4.12; 
  
 (5) Indebtedness of a Person that becomes a Restricted
Subsidiary or is acquired by the Issuer or a Restricted Subsidiary or merged into the Issuer or a Restricted Subsidiary in accordance with this Indenture and outstanding on the date on which such Person became a Restricted Subsidiary or was acquired
by or was merged into the Issuer or such Restricted Subsidiary (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
Person became a Restricted Subsidiary or was otherwise acquired by or was merged into the Issuer or a Restricted Subsidiary or (b) otherwise in connection with, or in contemplation of, such acquisition); provided, however, that at the
time such Person becomes a Restricted Subsidiary or is acquired by or was merged into the Issuer or a Restricted Subsidiary, the Issuer would have been able to Incur $1.00 of additional Indebtedness pursuant to the first paragraph of this
Section 4.12 after giving effect to the Incurrence of such Indebtedness pursuant to this clause (5); 
  
 (6) the Incurrence by the Issuer or any Restricted Subsidiary of Indebtedness represented by Capitalized 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 construction or improvements or carrying costs of property used in the business of the Issuer or such
Restricted Subsidiary, and Refinancing Indebtedness Incurred to Refinance any Indebtedness Incurred pursuant to this clause (6) in an aggregate outstanding principal amount which, when taken together with the 

  

 -86- 









 
principal amount of all other Indebtedness Incurred pursuant to this clause (6) and then outstanding, will not exceed $20 million at any time
outstanding; 
  
 (7) Indebtedness Incurred in
respect of (a) self-insurance obligations, bid, appeal, reimbursement, performance, surety and similar bonds and completion guarantees provided by the Issuer or a Restricted Subsidiary in the ordinary course of business and any Guarantees or
letters of credit functioning as or supporting any of the foregoing bonds or obligations and (b) obligations represented by letters of credit for the account of the Issuer or a Restricted Subsidiary in order to provide security for
workers’ compensation claims (in the case of clauses (a) and (b) other than for an obligation for money borrowed); 
  
 (8) Capital Stock (other than Disqualified Stock) of the Issuer or of any of the Subsidiary Guarantors; 
  
 (9) Indebtedness, including Refinancing Indebtedness,
Incurred by a Foreign Subsidiary in an aggregate amount not to exceed 15% of such Foreign Subsidiary’s Adjusted Consolidated Net Tangible Assets at any time outstanding; 
  
 (10) Any Guarantee by the Issuer or any Restricted Subsidiary that directly owns Capital Stock of the
Ethanol Subsidiary that is recourse only to, or secured only by, such Capital Stock; and 
  
 (11) in addition to the items referred to in clauses (1) through (10) above, Indebtedness of the Issuer 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 $30 million at any time
outstanding. 
  
 For purposes of determining compliance with, and
the outstanding principal amount of any particular Indebtedness Incurred pursuant to and in compliance with, this Section 4.12: 
  
 (1) in the event an item of that Indebtedness meets the criteria of more than one of the types of Indebtedness described in the first and
second paragraphs of this Section 4.12, the Issuer, in its sole discretion, will classify such item of Indebtedness on the date of Incurrence and, subject to clause (2) below may later 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 Incurred on the
Issue Date under clause (1) of the second paragraph of this Section 4.12; 
  

 -87- 









 (3) Guarantees of, or obligations in respect of letters of credit supporting,
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 Issuer 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 4.12 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 4.12 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 amortization of debt discount or the accretion of accreted value, the payment of interest in the form of
additional Indebtedness, the payment of dividends in the form of additional shares of Preferred Stock or Disqualified Stock and unrealized losses or charges in respect of Hedging Obligations (including those resulting from the application of FAS
133) will not be deemed to be an Incurrence of Indebtedness for purposes of this Section 4.12. 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. 
  
 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 4.12, the Issuer shall be in Default of
this Section 4.12). 
  
 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 

  

 -88- 









 
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 4.12, the maximum amount of Indebtedness that the Issuer may Incur pursuant to this Section 4.12 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. 
  
 This Indenture will not treat (1) unsecured Indebtedness as subordinated or junior to secured Indebtedness merely because it is unsecured or
(2) senior Indebtedness as subordinated or junior to any other senior Indebtedness merely because it has a junior priority with respect to the same collateral. 
  
 SECTION 4.13. Limitation on Restrictions on Distributions from Restricted Subsidiaries.

  
 The Issuer will not, and will 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 Issuer 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 Issuer or any Restricted Subsidiary (it being understood that the subordination of loans or advances
made to the Issuer or any Restricted Subsidiary to other Indebtedness Incurred by the Issuer or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or 
  
 (3) sell, lease or transfer any of its property or assets to
the Issuer or any Restricted Subsidiary. 
  

 -89- 









 The preceding provisions will not prohibit: 
  
 (i) any encumbrance or restriction pursuant to or by reason
of an agreement in effect at or entered into on the Issue Date, including, without limitation, this Indenture in effect on such date; 
  
 (ii) any encumbrance or restriction with respect to a Person pursuant to or by reason of an agreement relating to any Capital Stock or
Indebtedness Incurred by a Person on or before the date on which such Person was acquired by the Issuer or another Restricted Subsidiary (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 Person was acquired by the Issuer or a Restricted Subsidiary 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 Issuer or any other Restricted Subsidiary other than the assets and property so acquired; 
  
 (iii) encumbrances and restrictions contained in contracts
entered into in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of, or from the ability of the Issuer and the Restricted Subsidiaries to realize the value
of, property or assets of the Issuer or any Restricted Subsidiary in any manner material to the Issuer or any Restricted Subsidiary; 
  
 (iv) any encumbrance or restriction with respect to a Unrestricted Subsidiary pursuant to or by reason of an agreement that the
Unrestricted Subsidiary is a party to entered into before the date on which such Unrestricted Subsidiary became a Restricted Subsidiary; provided, that such agreement was not entered into in anticipation of the Unrestricted Subsidiary
becoming a Restricted Subsidiary and any such encumbrance or restriction shall not extend to any assets or property of the Issuer or any other Restricted Subsidiary other than the assets and property so acquired; 
  
 (v) with respect to any Foreign Subsidiary, any encumbrance
or restriction contained in the terms of any Indebtedness or any agreement pursuant to which such Indebtedness was Incurred if: 
  
 (a) either (1) the encumbrance or restriction applies only in the event of a payment default or a default with respect to a financial
covenant in such Indebtedness or agreement or (2) the Issuer determines that any such encumbrance or restriction will not materially affect the Issuer’s ability to make principal or interest payments on the Notes, as determined in good
faith by the Board of Directors of the Issuer, whose determination shall be conclusive; and 
  

 -90- 









 (b) the encumbrance or restriction is not materially more disadvantageous to the holders
of the Notes than is customary in comparable financing (as determined by the Issuer); 
  
 (vi) 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 clauses (i) through (v) or clause (xii) of this paragraph or this clause (vi) or contained in any amendment, restatement, modification, renewal,
supplemental, refunding, replacement or refinancing of an agreement referred to in clauses (i) through (v) or clause (xii) of this paragraph or this clause (vi); provided, however, that the encumbrances and restrictions with
respect to such Restricted Subsidiary contained in any such agreement taken as a whole are no less favorable in any material respect to the holders of the Notes than the encumbrances and restrictions contained in such agreements referred to in
clauses (i) through (v) or clause (xii) of this paragraph on the Issue Date or the date such Restricted Subsidiary became a Restricted Subsidiary or was merged into a Restricted Subsidiary, whichever is applicable; 
  
 (vii) in the case of clause (3) of the first paragraph
of this Section 4.13, 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 (including leases governing leasehold interests or farm-in agreements or farm-out
agreements relating to leasehold interests in oil and gas properties), license or similar contract, or the assignment or transfer of any such lease (including leases governing leasehold interests or farm-in agreements or farm-out agreements relating
to leasehold interests in oil and gas properties), license or other contract; 
  
 (b) contained in mortgages, pledges or other security agreements permitted under this Indenture securing Indebtedness of the Issuer 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; 
  
 (c) pursuant to customary provisions restricting dispositions of real property interests set forth in any reciprocal easement agreements
of the Issuer or any Restricted Subsidiary; 
  
 (d) restrictions on cash or other deposits imposed by customers under contracts entered into in the ordinary course of business; or 
  

 -91- 









 (e) provisions with respect to the disposition or distribution of assets or property in
operating agreements, joint venture agreements, development agreements, area of mutual interest agreements and other agreements that are customary in the Oil and Gas Business and entered into in the ordinary course of business; 
  
 (viii) (a) 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 4.13 on the property so acquired; 
  
 (ix) any encumbrance or 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; 
  
 (x) any customary encumbrances or restrictions imposed pursuant to any agreement of the type described in
the definition of “Permitted Business Investment”; 
  
 (xi) encumbrances or restrictions arising or existing by reason of applicable law or any applicable rule, regulation or order; and 
  
 (xii) the Senior Secured Credit Agreement as in effect as of the Issue Date, and any amendments,
modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof, provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or
refinancings are no more restrictive with respect to such dividend and other payment restrictions than those contained in the Senior Secured Credit Agreement as in effect on the Issue Date. 
  
 SECTION 4.14. Payments for Consents. 
  
 Neither the Issuer nor any of its Restricted Subsidiaries will, directly or
indirectly, pay or cause to be paid any consideration, whether by way of interest, fees or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless
such consideration is offered to be paid or is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment. 
  

 -92- 









 SECTION 4.15. Change of Control. 
  
 If a Change of Control occurs, unless the Issuer has previously or
concurrently exercised its right to redeem all of the Notes pursuant to Section 3.3, each Holder will have the right to require the Issuer to repurchase all or any part (equal to $2,000 or an integral multiple thereof) of such Holder’s
Notes at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and unpaid interest, if any, and Liquidated Damages, if any, to the date of purchase (subject to the right of holders of record on the relevant record
date to receive interest due on the relevant interest payment date). 
  
 Within 30 days following any Change of Control, unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes pursuant to Section 3.3, the Issuer will mail a notice (the “Change of Control
Offer”) to each Holder, with a copy to the Trustee, stating: 
  
 (1) that a Change of Control has occurred and that such Holder has the right to require the Issuer to purchase such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount of such Notes
plus accrued and unpaid interest, if any, and Liquidated Damages, if any, to the date of purchase (subject to the right of holders of record on a record date to receive interest on the relevant interest payment date) (the “Change of Control
Payment”); 
  
 (2) the repurchase date
(which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed) (the “Change of Control Payment Date”); 
  
 (3) that any Note not properly tendered will remain outstanding and continue to accrue interest; 
  
 (4) that unless the Issuer defaults in the payment of the
Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control Payment Date; 
  
 (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required
to surrender such Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the paying agent specified in the notice at the address specified in the notice prior to the close of business
on the third Business Day preceding the Change of Control Payment Date; 
  
 (6) that Holders will be entitled to withdraw their tendered Notes and their election to require the Issuer to purchase such Notes, provided that the paying agent receives, not later than the close of business
on the 30th day following the date of the Change of Control notice, a telegram, telex, facsimile transmission or letter setting 

  

 -93- 









 
forth the name of the Holder, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its
election to have such Notes purchased; 
  
 (7)
that if the Issuer is redeeming less than all of the Notes, the Holders of the remaining Notes will be issued new Notes and such new Notes will be equal in principal amount to the unpurchased portion of the Notes surrendered. The unpurchased portion
of the Notes must be equal to $2,000 or an integral multiple thereof; and 
  
 (8) the procedures determined by the Issuer, consistent with this Indenture, that a Holder must follow in order to have its Notes repurchased. 
  
 On the Change of Control Payment Date, the Issuer will, to the extent lawful: 
  
 (1) accept for payment all Notes or portions of Notes (in
integral multiples of $2,000) properly tendered pursuant to the Change of Control Offer; 
  
 (2) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly
tendered and not properly withdrawn; and 
  
 (3)
deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer. 
  
 The paying agent will promptly mail to each Holder properly tendered and not
properly withdrawn the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the
Notes surrendered, if any; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple thereof. 
  
 If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid
interest, and Liquidated Damages, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no further interest will be payable to holders who tender pursuant to the Change of Control
Offer. 
  
 The Change of Control provisions described above will
be applicable whether or not any other provisions of this Indenture are applicable. Except as described above with respect to a Change of Control, this Indenture does not contain provisions that permit the 

  

 -94- 









 
Holders to require that the Issuer repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction. 
  
 The Issuer will not be required to make a Change of Control Offer upon a
Change of Control if 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 Issuer and purchases
all Notes validly tendered and not withdrawn under such Change of Control Offer. 
  
 The Issuer will comply, to the extent applicable, with the requirements of Rule 14e-1 of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes as a result of a Change
of Control. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Indenture, or compliance with the Change of Control provisions of this Indenture would constitute a violation of any such laws or
regulations, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations described in this Indenture by virtue of its compliance with such securities laws or regulations.

  
 SECTION 4.16. Limitation on Sales of Assets and
Subsidiary Stock. 
  
 The Issuer will not, and will
not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless: 
  
 (1) the Issuer 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 received by the Issuer or such Restricted Subsidiary, as the case may be, from such Asset Disposition is in the form of cash or Cash Equivalents or Additional Assets, or any
combination thereof; and 
  
 (3) except as
provided in the next paragraph an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied, within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, by the Issuer or
such Restricted Subsidiary, as the case may be: 
  
 (a) to the extent the Issuer or any Restricted Subsidiary, as the case may be, elects (or is required by the terms of any Indebtedness), to prepay, repay, redeem or purchase Indebtedness of the Issuer under the Senior Secured 

  

 -95- 









 
Credit Agreement, any other Indebtedness of the Issuer or a Subsidiary Guarantor that is secured by a Lien permitted to be Incurred under this Indenture or
Indebtedness (other than Disqualified Stock) of any Wholly-Owned Subsidiary that is not a Subsidiary Guarantor; provided, however, that, in connection with any prepayment, repayment, redemption or purchase of Indebtedness pursuant to this
clause (a), the Issuer 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; or 
  
 (b) to invest in Additional Assets; 
  
 provided that pending the final application of any such Net Available
Cash in accordance with this Section 4.16, the Issuer and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise invest such Net Available Cash in any manner not prohibited by this Indenture. 
  
 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.” Not later than the day following the date that is one year from the later of the date of such Asset Disposition or the receipt of such
Net Available Cash, if the aggregate amount of Excess Proceeds exceeds $15.0 million, the Issuer will be required to make an offer (“Asset Disposition Offer”) to all Holders 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 Issuer 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 Notes 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 (or, in the event such Pari Passu Indebtedness of the Issuer was issued with significant original issue discount, 100% of the accreted value thereof) of the Notes and Pari Passu Notes plus accrued and unpaid interest and
Liquidated Damages, if any, (or in respect of such Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Indebtedness) to the date of purchase (subject to the right of holders of record on the relevant
record date to receive interest due on the relevant interest payment date), 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 $2,000.
If the aggregate principal amount of Notes 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 Notes to be purchased on a pro
rata basis on the basis of the aggregate principal amount of tendered Notes and Pari Passu Notes. To the extent that the aggregate amount of Notes and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to an Asset Disposition
Offer is less than the Excess Proceeds, the Issuer may use any remaining 

  

 -96- 









 
Excess Proceeds for general corporate purposes, subject to the other covenants contained in this Indenture. Upon completion of such Asset Disposition Offer,
the amount of Excess Proceeds shall be reset at zero. 
  
 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 Issuer will purchase the principal amount of Notes and Pari Passu Notes required to be purchased pursuant to this
Section 4.16 (the “Asset Disposition Offer Amount”) or, if less than the Asset Disposition Offer Amount has been so validly tendered, all Notes and Pari Passu Notes validly tendered in response to the Asset Disposition Offer.

  
 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 and Liquidated Damages, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and
no further interest or Liquidated Damages will be payable to holders who tender Notes pursuant to the Asset Disposition Offer. 
  
 On or before the Asset Disposition Purchase Date, the Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary,
the Asset Disposition Offer Amount of Notes and Pari Passu Notes or portions of Notes 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 Notes and Pari Passu Notes so validly tendered and not properly withdrawn, in each case in integral multiples of $2,000. The Issuer will deliver to the Trustee an Officers’ Certificate
stating that such Notes or portions thereof were accepted for payment by the Issuer in accordance with the terms of this Section 4.16 and, in addition, the Issuer will deliver all certificates and notes required, if any, by the agreements
governing the Pari Passu Notes. The Issuer 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 or holder or lender of Pari Passu Notes, as the case may be, an amount equal to the purchase price of the Notes 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 Issuer for purchase, and the Issuer will promptly issue a new Note, and the Trustee, upon delivery of an Officers’ Certificate from the Issuer, will authenticate and mail or deliver such new Note to such Holder, in a principal amount equal
to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $2,000. In addition, the Issuer will take any and all other actions required by the
agreements governing the Pari Passu Notes. Any Note not so accepted will be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer will publicly announce the results of the Asset Disposition Offer on the Asset Disposition
Purchase Date.

release, the agreement of the acquirer or its parent company to indemnify and hold the Issuer or such Restricted Subsidiary harmless from and against any loss, liability or cost in respect of such assumed Indebtedness; provided,
however, that such indemnifying party (or its long term debt securities) shall have an Investment Grade Rating (with no indication of a negative outlook or credit watch with negative implications, in any case, that contemplates such
indemnifying party (or its long term debt securities) failing to have an Investment Grade Rating), in which case the Issuer will, without further action, be deemed to have applied such deemed cash to Indebtedness in accordance with clause
(3)(a) of the first paragraph of this Section 4.16; and 
  
 (2) securities, notes or other obligations received by the Issuer or any Restricted Subsidiary from the transferee that are converted by the Issuer or such Restricted Subsidiary into cash within 90 days after receipt

accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Disposition complied with the aforementioned 75% limitation. 
  
 The requirement of clause (3)(b) of the first paragraph of this
Section 4.16 above shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or expenditures referred to therein is entered into by the Issuer or its
Restricted Subsidiary within the specified time

 SECTION 4.18. Limitation on Liens. 
  
 The Issuer will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, Incur or suffer to exist any Lien (the “Initial Lien”) other than Permitted Liens upon any of its property or assets (including Capital Stock of Restricted Subsidiaries), including any income or
profits therefrom, 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 the Notes 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 senior in priority 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. 
  
 Any Lien created for the benefit of the holders of the Notes pursuant to the preceding paragraph shall provide by its terms
that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien. 
  
 SECTION 4.19. Limitation on Lines of Business.

 If any of the Issuer’s Restricted Subsidiaries that is not a Subsidiary Guarantor other than a Foreign Subsidiary
incurs or guarantees any Indebtedness, then the Issuer shall cause such Restricted Subsidiary to become a Subsidiary Guarantor; provided that any Restricted Subsidiary that constitutes an Immaterial Subsidiary need not become a Subsidiary
Guarantor until such time as it ceases to be an Immaterial Subsidiary. If required to become a Subsidiary Guarantor pursuant to the immediately preceding sentence, such transferee or acquired or other Restricted Subsidiary shall: 
  
 (1) execute and deliver to the Trustee a supplemental
indenture in form reasonably satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally guarantee all of the Issuer’s obligations under the Notes and this Indenture on the terms set forth in this Indenture;

 ARTICLE VI. 
  
 REMEDIES 
  
 SECTION 6.1. Events of Default. 
  
 An “Event of Default” means any of the following events: 
  
 (1) default in any payment of interest or Liquidated Damages
on any Note when due, continued for 30 days; 
  
 (2) default in the payment of principal of or premium, if any, on any Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration of acceleration or otherwise; 
  
 (3) failure by the Issuer or any Subsidiary Guarantor to
comply with its obligations under Section 5.1; 
  
 (4) failure by the Issuer to comply for 30 days after notice as provided below with any of its obligations under Sections 4.8, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.18, 4.19 or 4.20 above (in each case, other than a failure to purchase
Notes which will constitute an Event of Default under clause (2) above); 
  
 (5) failure by the Issuer to comply for 60 days after notice as provided below with its other agreements contained in this Indenture; 
  
 (6) 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 Issuer or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Issuer or any of its Restricted Subsidiaries), other than Indebtedness owed to the
Issuer 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 (and any extensions of any grace period) (“payment default”); or 
  

 -102- 









 (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 $15.0 million or
more; 
  
 (7) certain events of bankruptcy,
insolvency or reorganization of the Issuer or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Issuer and its Restricted Subsidiaries), would
constitute a Significant Subsidiary (the “bankruptcy provisions”); 
  
 (8) failure by the Issuer or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited
consolidated financial statements for the Issuer and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $15.0 million (to the extent not covered by insurance by a reputable and
creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid or discharged, and there shall be any period of 60 consecutive days following entry of such final judgment or decree during which a stay of
enforcement of such final judgment or decree, by reason of pending appeal or otherwise, shall not be in effect (the “judgment default provision”); or 
  
 (9) any Subsidiary Guarantee of a Significant Subsidiary or group of Restricted Subsidiaries that, taken
together (as of the latest audited consolidated financial statements for the Issuer and its Restricted Subsidiaries) would constitute a Significant Subsidiary ceases to be in full force and effect (except as contemplated by the terms of this
Indenture) or is declared 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 of the
Issuer and its Restricted Subsidiaries) would constitute a Significant Subsidiary denies or disaffirms its obligations under this Indenture or its Subsidiary Guarantee. 
  
 However, a default under clauses (4) and (5) of this paragraph will not constitute an Event of Default until the Trustee or the
holders of 25% in principal amount of the outstanding Notes notify the Issuer in writing and, in the case of a notice given by the holders, the Trustee of the 

  

 -103- 









 
default and the Issuer does not cure such default within the time specified in clauses (4) and (5) of this paragraph after receipt of such notice.

  
 SECTION 6.2. Acceleration. 
  
 If an Event of Default (other than an Event of Default described in clause
(7) above) occurs and is continuing, the Trustee by notice to the Issuer, or the holders of at least 25% in principal amount of the outstanding Notes by notice to the Issuer and the Trustee, may, and the Trustee at the request of such holders
shall, declare the principal of, premium, if any, accrued and unpaid interest, if any, and Liquidated Damages, if any, on all the Notes to be due and payable. If an Event of Default described in clause (7) above occurs and is continuing, the
principal of, premium, if any, accrued and unpaid interest and Liquidated Damages, if any, on all the Notes 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 Notes may waive all past defaults (except with respect to nonpayment of principal, premium, interest or Liquidated Damages, if any) and rescind any such acceleration with respect to the Notes 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
Notes 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 by proceeding at law or in equity to collect the payment of
the principal of, premium and Liquidated Damages, if any, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
  
 All rights of action and claims under this Indenture or the Notes may be enforced by the Trustee even if it does not possess
any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of
or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. 
  
 SECTION 6.4. Waiver of Past Defaults. 
  
 At any time prior to the declaration of acceleration of the Notes, the Holders of not less than a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may, on behalf of the Holders of all the Notes, waive any existing Default or Event of Default and its consequences under this Indenture, except a Default or Event of Default specified in Section 6.1(1) or
(2) or in respect of any provision hereof which cannot be 

  

 -104- 









 
modified or amended without the consent of the Holder so affected pursuant to Section 9.2. When a Default or Event of Default is so waived, it shall be
deemed cured and shall cease to exist. This Section 6.4 shall be in lieu of § 316(a)(1)(B) of the TIA and such § 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the
TIA. 
  
 SECTION 6.5. Control by Majority.

  
 Holders of the Notes may not enforce this Indenture or the
Notes except as provided in this Article VI and under the TIA. The Holders of not less than a majority in aggregate principal amount of the outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, provided, however, that the Trustee may refuse to follow any direction (a) that conflicts with any rule of law or this Indenture,
(b) that the Trustee reasonably determines may be unduly prejudicial to the rights of any other Holder, or (c) that may expose the Trustee to personal liability for which reasonable indemnity provided to the Trustee against such liability
shall be deemed inadequate by the Trustee; provided, further, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction or this Indenture. This Section 6.5
shall be in lieu of § 316(a)(1)(A) of the TIA, and such § 316(a)(1)(A) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA. 
  
 SECTION 6.6. Limitation on Suits. 
  
 Subject to the provisions of this Indenture relating to the duties of the
Trustee, if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the holders unless such Holders have offered to the
Trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with respect to this Indenture or
the Notes unless: 
  
 (1) such Holder has
previously given the Trustee notice that an Event of Default is continuing; 
  
 (2) Holders of at least 25% in principal amount of the outstanding Notes have requested the Trustee to pursue the remedy; 
  
 (3) such Holder has offered the Trustee reasonable security or indemnity against any loss, liability or expense; 
  
 (4) the Trustee has not complied with such request within 60
days after the receipt of the request and the offer of security or indemnity; and 
  

 -105- 









 (5) the Holders of a majority in principal amount of the outstanding Notes have not
waived such Event of Default or otherwise given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period. 
  
 A Holder may not use this Indenture to prejudice the rights of any other Holders or to obtain priority or preference over
such other Holders. 
  
 SECTION 6.7. Right of Holders To
Receive Payment. 
  
 Notwithstanding any
other provision in this Indenture, the right of any Holder of a Note to receive payment of the principal of, premium and Liquidated Damages, if any, and interest on such Note, on or after the respective due dates expressed or provided for in such
Note, or to bring suit for the enforcement of any such payment on or after the respective due dates, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder. 
  
 SECTION 6.8. Collection Suit by Trustee.

  
 If an Event of Default specified in clause (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 Issuer, or any other obligor on the Notes for the whole amount of the principal of, premium, if
any, Liquidated Damages, if any, and accrued interest remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate
per annum provided for by the Notes and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

  
 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 (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents, counsel, accountants and
experts) and the Holders allowed in any judicial proceedings relative to the Issuer or Restricted Subsidiaries (or any other obligor upon the Notes), their creditors or their property and shall be entitled and empowered to collect and receive any
monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings is hereby authorized by each Holder to make such 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 to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agent and counsel, and any other
amounts due the Trustee under Section 7.7. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt 

  

 -106- 









 
on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 SECTION 6.10. Priorities. 
  
 If the Trustee collects any money pursuant to this Article VI it shall pay out such money in the following order: 
  
 First: to the Trustee for amounts due under Section 7.7; 
  
 Second: to Holders for interest accrued on the Notes, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Notes for interest; 
  
 Third: to Holders for the principal amounts (including any premium or Liquidated Damages) owing under the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the
Notes for the principal (including any premium or Liquidated Damages); and 
  
 Fourth: the balance, if any, to the Issuer. 
  
 The Trustee, upon prior written notice to the Issuer, may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. 
  
 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 may in its discretion 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 any suit by the Trustee, any suit
by a Holder pursuant to Section 6.7, or a suit by a Holder or Holders of more than 10% in aggregate principal amount of the outstanding Notes. 
  
 SECTION 6.12. Restoration of Rights and Remedies. 
  
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture or any Note
and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case the Issuer, the Trustee and the Holders shall, subject to any determination in such
proceeding, be restored severally and respectively to their former 

  

 -107- 









 
positions under this Indenture, and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been
instituted.

in the case of any such certificates or opinions that by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the
requirements of this Indenture. 
  
 (c) Notwithstanding anything
to the contrary herein contained, 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:

in good faith in accordance with a direction received by it pursuant to Section 6.2, 6.4 or 6.5. 
  
 (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance

be genuine and to have been signed or presented by the proper Person or Persons or to have been prepared and furnished pursuant to any of the provisions of this Indenture; and the Trustee shall be under no duty to make any investigation as to any
statement contained in any such instance, but may accept the same conclusive evidence of the truth and accuracy of such statement or the correctness of such opinions. The Trustee need not investigate any fact or matter stated in the document.

  
 (b) Before the Trustee acts or refrains from
acting, it may consult with counsel of its selection and may require an Officers’ Certificate or an Opinion of Counsel, which shall conform to Sections 11.4 and 11.5. The Trustee shall not be liable for any action it takes or omits to take

stated in any resolution, certificate, statement, instrument, opinion, notice, request, direction, consent, order, bond, debenture, or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into

 (i) Other than a consent revoked in accordance with Section 9.4, any action taken, or omitted to be taken, by the Trustee in good
faith pursuant to this Indenture upon the request or authority or consent of any person who, at the time of making such request or giving such authority or consent, is a Holder shall be conclusive and binding upon every subsequent Holder of a Note
or portion of a Note that evidences the same debt as the requesting or consenting Holder’s Note. 
  
 SECTION 7.3. Individual Rights of Trustee. 
  
 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer, any of its respective
Subsidiaries, or its respective Affiliates with the same rights it would have if it were not Trustee. Any 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 makes no representation as to the validity or adequacy of this
Indenture or the Notes, and it shall not be accountable for the Issuer’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuer in this Indenture or the Notes other than the Trustee’s
certificate of authentication. 
  
 Under no circumstances shall
the Trustee be liable in its individual capacity for the obligations evidenced by the Notes. In accepting the trust hereby created, the Trustee acts solely as Trustee for the Holders and not in its individual capacity and all persons, including
without limitation the Holders and the Issuer having any claim against the Trustee arising from this Indenture shall look only to the funds and accounts held by the Trustee hereunder for payment except as otherwise provided herein. 
  
 SECTION 7.5. Notice of Default. 
  
 If a Default or an Event of Default occurs and is continuing, of which the
Trustee is deemed to have notice, the Trustee shall mail to each Holder notice of the uncured Default or Event of Default within 90 days after obtaining knowledge thereof. Except in the case of a Default or an Event of Default in payment of
principal of, premium or Liquidated Damages, if any, or interest on, any Note, including an accelerated payment, a Default in payment on the Change of Control Payment Date pursuant to a Change of Control Offer or on the Asset Disposition Purchase
Date pursuant to an Asset Disposition Offer and a Default in compliance with Article V hereof, the Trustee may withhold the notice if and so long as its Board of Directors, the executive committee of its Board of Directors or a committee of its
directors and/or Trust Officers in good faith determines that withholding the notice is in the interest of the Holders. The foregoing sentence of this Section 7.5 shall be in lieu of the proviso to § 315(b) of the TIA and such proviso
to § 315(b) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA. 
  
 SECTION 7.6. Reports by Trustee to Holders. 
  

Within 60 days after May 15 of each year beginning with 2006 and for so long as Notes remain outstanding, the Trustee shall, to the extent that
any of the events described in TIA § 313(a) occurred within the previous twelve months, but not otherwise, mail to each Holder a brief report dated as of such date that complies with TIA § 313(a). The Trustee also shall comply
with TIA §§ 313(b), (c) and (d). 
  
 A copy of
each report at the time of its mailing to Holders shall be mailed to the Issuer. 
  
 The Issuer shall promptly notify the Trustee if the Notes become listed on any stock exchange and the Trustee shall comply with TIA § 313(d). 
  

 -111- 









 SECTION 7.7. Compensation and Indemnity. 
  
 The Issuer shall pay to the Trustee from time to time such compensation for
its services as has been agreed to in writing signed by the Issuer and the Trustee. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request
for all reasonable out-of-pocket expenses incurred or made by it in connection with the performance of its duties under this Indenture. Such expenses shall include the reasonable fees and expenses of the Trustee’s agents, counsel, accountants
and experts. 
  
 The Issuer and the Guarantors shall indemnify
each of the Trustee (or any predecessor Trustee) and its agents, employees, stockholders, Affiliates and directors and officers for, and hold them each harmless against, any and all loss, liability, damage, claim or expense (including reasonable
fees and expenses of counsel), including taxes (other than taxes based on the income of the Trustee) incurred by them except for such actions to the extent caused by any negligence, bad faith or willful misconduct on their part, arising out of or in
connection with the acceptance or administration of this Indenture including the reasonable costs and expenses of defending themselves against any claim or liability in connection with the exercise or performance of any of their rights, powers or
duties under this Indenture. The Trustee shall notify the Issuer promptly of any claim asserted against the Trustee for which it may seek indemnity. At the Trustee’s sole discretion, the Issuer or such Guarantor shall defend the claim and the
Trustee shall cooperate and may participate in the defense; provided, however, that any settlement of a claim shall be approved in writing by the Trustee if such settlement would result in an admission of liability by the Trustee or if
such settlement would not be accompanied by a full release of the Trustee for all liability arising out of the events giving rise to such claim. Alternatively, the Trustee may at its option have separate counsel of its own choosing and the Issuer
shall pay the reasonable fees and expenses of such counsel. 
  
 To
secure the Issuer’s and the Guarantors’ payment obligations in this Section 7.7, the Trustee shall have a Lien prior to the Notes on all assets or money held or collected by the Trustee, in its capacity as Trustee, except assets or
money held in trust to pay principal of or premium, if any, or interest on particular Notes. 
  
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(7) or (8) occurs, such expenses and the compensation for such services are intended to constitute
expenses of administration under any Bankruptcy Law. 
  
 The
provisions of this Section 7.7 shall survive the termination of this Indenture or the earlier resignation or removal of the Trustee. 
  

 -112- 









 SECTION 7.8. Replacement of Trustee. 
  
 The Trustee may resign at any time by so notifying the Issuer. The Holders of
a majority in principal amount of the outstanding Notes may remove the Trustee and appoint a successor Trustee with the Issuer’s consent, by so notifying the Issuer and the Trustee. The Issuer may 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 becomes incapable of acting. 
  
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall notify each Holder of such event and shall promptly appoint a successor Trustee. Within one year
after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer. 
  
 A successor Trustee shall deliver a written acceptance of its appointment to
the retiring Trustee and to the Issuer. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided in Section 7.7, 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 Issuer shall mail notice of such successor Trustee’s appointment to each Holder.

  
 If a successor Trustee does not take office within 45 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least 10% in aggregate principal amount of the outstanding Notes may petition any court of competent jurisdiction for the appointment of a
successor Trustee. 
  
 If the Trustee fails to comply with
Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 Notwithstanding any resignation or replacement of the Trustee pursuant to this Section 7.8, the Issuer’s obligations under Section 7.7
shall continue for the benefit of the retiring Trustee. 
  

 -113- 









 SECTION 7.9. Successor Trustee by Merger, Etc. 
  
 If the Trustee consolidates with, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible under this
Indenture, be the successor Trustee; provided, however, that such corporation shall be otherwise qualified and eligible under this Article VII. 
  
 SECTION 7.10. Eligibility; Disqualification. 
  
 This Indenture shall always have a Trustee who satisfies the requirement of
TIA §§ 310(a)(1), (2) and (5). The Trustee (or, in the case of a Trustee that is a corporation included in a bank holding company system, the related bank holding company) shall have a combined capital and surplus of at least
$150 million as set forth in its most recent published annual report of condition and have a Corporate Trust Office in the City of New York. In addition, if the Trustee is a corporation included in a bank holding company system, the Trustee,
independently of such bank holding company, shall meet the capital requirements of TIA § 310(a)(2). 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 Issuer are outstanding, if the requirements for such exclusion set forth in TIA
§ 310(b)(1) are met. The provisions of TIA § 310 shall apply to the Issuer, as obligor of the Notes. 
  
 SECTION 7.11. Preferential Collection of Claims Against the Issuer. 
  
 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 therein. The provisions of TIA § 311 shall apply to the Issuer, as obligor on the Notes. 
  
 SECTION 7.12. Force Majeure. 
  
 In no event shall the Trustee be liable for any failure or delay in the
performance of its obligations under this Indenture because of circumstances beyond the Trustee’s control, including, but not limited to, acts of God, flood, war (whether declared or undeclared), terrorism, fire, riot, embargo, government
action, including any laws, ordinances, regulations, governmental action or the like which delay, restrict or prohibit the providing of the services contemplated by this Indenture. 
  

 -114- 









 SECTION 7.13. Defaults and Events of Default. 
  
 The Trustee shall not be required to take notice or be deemed to have notice
of any Default, except failure of the Issuer to cause to be made any of the payments required to be made to the Trustee, unless the Trustee shall be specifically notified by a writing of such Default by the Issuer or by the Holders of at least 25%
in aggregate principal amount of all Notes then outstanding delivered to the Corporate Trust Office of the Trustee and, in the absence of such notice so delivered, the Trustee may conclusively assume no Default exists. 
  
 ARTICLE VIII. 
  
 DISCHARGE OF INDENTURE; DEFEASANCE 
  

SECTION 8.1. Termination of Issuer’s Obligations. 
  
 This Indenture will be discharged and will cease to be of further effect (except as to surviving rights of registration of
transfer or exchange of the Notes, as expressly provided for in this Indenture) as to all outstanding Notes when (a) either (i) all the Notes, theretofore authenticated (except lost, stolen or destroyed Notes that have been replaced or
paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust) have been delivered to the Trustee for cancellation or
(ii) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the giving of a notice of redemption or otherwise and the Issuer or any Subsidiary
Guarantor has irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust solely for such purpose, cash in U.S. dollars, 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 the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Notes to
the date of maturity or redemption together with irrevocable instructions from the Issuer directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be; (b) the Issuer has paid all other sums
payable under this Indenture by the Issuer; and (c) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and
discharge of this Indenture have been complied with; provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Issuer. 
  
 The Issuer may, at its option and at any time, elect to have its obligations
and the corresponding obligations of the Subsidiary Guarantors discharged with respect to the outstanding Notes and Subsidiary Guarantees (“Legal Defeasance”). Such Legal Defeasance 

  

 -115- 









 
means that the Issuer shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes, and satisfied all of its
obligations with respect to the Notes, except for: (1) the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due, (2) the Issuer’s obligations with
respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payments, (3) the rights, powers, trust, duties and immunities of the
Trustee and the Issuer’s obligations in connection therewith and (4) the Legal Defeasance provisions of this Section 8.1. In addition, the Issuer may, at its option and at any time, elect to terminate its obligations with respect to
covenants contained in Sections 4.4, 4.5, 4.8 and 4.10 through 4.20 and Article V and the operation of clauses (6), (7) (with respect to Significant Subsidiaries), (8) and (9) of Section 6.1 and the limitations described in
clause (3) of the first paragraph of Section 5.1 (“Covenant Defeasance”) and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the Notes. The Issuer
may exercise its Legal Defeasance option notwithstanding its prior exercise of its Covenant Defeasance option. In the event of Legal Defeasance, payment of the Notes may not be accelerated because of an Event of Default with respect thereto. In the
event of Covenant Defeasance, payment of the Notes may not be accelerated because of an Event of Default specified in clause (4), (5), (6), (7) (with respect to only to Significant Subsidiaries), (8) or (9) of Section 6.1 or
because of the failure of the Issuer to comply with clause (3) of the first paragraph of Section 5.1. 
  
 In order to exercise either Legal Defeasance or Covenant Defeasance: 
  
 (1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders cash in
United States dollars, non-callable U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if
any, and interest on the Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be; 
  
 (2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably
acceptable to the Trustee confirming that (a) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (b) 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 Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 
  

 -116- 









 (3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an
Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
  
 (4) no Default or Event of Default, of which the Trustee is deemed to have notice, shall have occurred and be continuing on the date of
such deposit or insofar as Events of Default under Section 6.1(7) or (8) from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit; 
  
 (5) 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 agreement or instrument to which the Issuer or any of its Restricted Subsidiaries is a party or by which the Issuer or any of its Restricted Subsidiaries
is bound; 
  
 (6) the Issuer shall have delivered
to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuer with the intent of preferring the Holders over any other creditors of the Issuer or with the intent of defeating, hindering, delaying or defrauding any
other creditors of the Issuer or any Guranantor or others; 
  
 (7) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant
Defeasance, as the case may be, have been complied with; provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Issuer; and 
  
 (8) the Issuer shall have delivered to the Trustee an
Opinion of Counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally;
provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Issuer. 
  
 SECTION 8.2. Application of Trust Money. 
  
 The Trustee or Paying Agent shall hold in trust U.S. Legal Tender or U.S. Government Obligations deposited with it pursuant to Section 8.1, and shall
apply the deposited U.S. Legal Tender and the money from U.S. Government Obligations in accordance with this Indenture to the payment of the principal of, premium and Liquidated Damages, if any, 

  

 -117- 









 
and interest on the Notes. The Trustee shall be under no obligation to invest said U.S. Legal Tender or U.S. Government Obligations except as it may agree in
writing with the Issuer. 
  
 The Issuer and the Guarantors shall
pay jointly and severally and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Legal Tender or U.S. Government Obligations deposited pursuant to Section 8.1 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of outstanding Notes. 
  
 SECTION 8.3. Repayment to the Issuer. 
  
 Subject to Section 8.1, the Trustee and the Paying Agent shall promptly pay to the Issuer upon request any excess U.S. Legal Tender or U.S.
Government Obligations held by them at any time and thereupon shall be relieved from all liability with respect to such money. The Trustee and the Paying Agent shall pay to the Issuer upon request any money held by them for the payment of principal,
interest or premium or Liquidated Damages, if any, that remains unclaimed for one year; provided, however, that the Trustee or such Paying Agent, before being required to make any payment, may at the expense of the Issuer cause to be
published once in a newspaper of general circulation in the City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein which shall be at least 30 days from the date
of such publication or mailing any unclaimed balance of such money then remaining will be repaid to the Issuer. After payment to the Issuer, Holders entitled to such money must look to the Issuer for payment as general creditors unless an applicable
law designates another Person. 
  
 SECTION 8.4.
Reinstatement. 
  
 If the Trustee or Paying
Agent is unable to apply any U.S. Legal Tender or U.S. Government Obligations in accordance with Section 8.1 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 Issuer’s and the Guarantors’ obligations under this Indenture and the Notes and the Subsidiary Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.1 until such time as the Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender or U.S. Government Obligations in accordance with Section 8.1; provided, however, that if the Issuer has made any
payment of interest or premium or Liquidated Damages, if any, on or principal of any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the
U.S. Legal Tender or U.S. Government Obligations held by the Trustee or Paying Agent. 
  

 -118- 









 SECTION 8.5. Acknowledgment of Discharge by Trustee. 
  
 After (i) the conditions of Section 8.1 have been satisfied,
(ii) the Issuer has paid or caused to be paid all other sums payable under this Indenture by the Issuer and (iii) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent referred to in clause (i) of this Section 8.5 relating to the satisfaction and discharge of this Indenture have been complied with, the Trustee upon request shall acknowledge in writing the discharge of the
Issuer’s obligations under this Indenture except for those surviving obligations specified in Section 8.1, provided the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers’
Certificates of the Issuer. 
  
 ARTICLE IX. 
  
 MODIFICATION OF THE INDENTURE 
  
 SECTION 9.1. Without Consent of Holders. 
  
 Without the consent of any Holder, the Issuer, the Guarantors and the Trustee
may amend this Indenture and the Notes to: 
  
 (1) cure any ambiguity, omission, defect, mistake or inconsistency; 
  
 (2) provide for the assumption by a successor corporation of the obligations of the Issuer or any Subsidiary Guarantor under this Indenture; 
  
 (3) provide for uncertificated Notes in addition to or in place of certificated Notes (provided that
the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f) (2) (B) of the Code); 
  
 (4) add Guarantees with respect to the Notes, including
Subsidiary Guarantees, or release a Subsidiary Guarantor from its Subsidiary Guarantee and terminate such Subsidiary Guarantee; provided, however, that the release and termination is in accord with the applicable provisions of this
Indenture; 
  
 (5) secure the Notes or Subsidiary
Guarantees; 
  
 (6) add to the covenants of the
Issuer or a Subsidiary Guarantor for the benefit of the Holders or surrender any right or power conferred upon the Issuer or a Subsidiary Guarantor; 
  

 -119- 









 (7) make any change that does not adversely affect the rights of any Holder; 

 
 (8) comply with any requirement of the SEC in connection
with the qualification of this Indenture under the Trust Indenture Act; 
  
 (9) provide for the issuance of exchange securities which shall have terms substantially identical in all respects to the Notes (except that the transfer restrictions contained in the Notes shall be modified or
eliminated as appropriate) and which shall be treated, together with any outstanding Notes, as a single class of securities; or 
  
 (10) provide for the succession of a successor Trustee. 
  
 SECTION 9.2. With Consent of Holders. 
  
 All other modifications and amendments of this Indenture may be made, subject to certain exceptions, with the consent of the
Holders of a majority in principal amount of the Notes then outstanding (including without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) and, subject to certain exceptions, any past
default or compliance with any provisions may be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender
offer or exchange offer for, Notes). However, without the consent of each Holder of an outstanding Note affected, no amendment may, among other things: 
  
 (1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 
  
 (2) reduce the stated rate of or extend the stated time for
payment of interest on any Note; 
  
 (3) reduce
the principal of or extend the Stated Maturity of any Note; 
  
 (4) reduce the premium payable upon the redemption of any Note pursuant to Section 3.3, or change the time at which any Note may be redeemed pursuant to Section 3.3, or make any change to the covenants
described in Section 4.15 after the occurrence of a Change of Control, or make any change to the provisions relating to 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 Note payable in money other than that stated in the Note; 
  

 -120- 









 (6) impair the right of any Holder to receive payment of, premium, if any, principal of
and interest on such Holder’s Notes 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 Notes; 
  
 (7) make any change in the amendment provisions which require each Holder’s consent or in the waiver
provisions; 
  
 (8) modify the Subsidiary
Guarantees in any manner adverse to the holders of the Notes; or 
  
 (9) make any change to or modify the ranking of the Notes that would adversely affect the Holders. 
  
 The consent of the Holders is not necessary under this Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the
substance of the proposed amendment. A consent to any amendment or waiver under this Indenture by any Holder given in connection with a tender of such Holder’s Notes will not be rendered invalid by such tender. After an amendment under this
Indenture becomes effective, the Issuer is required to mail to the Holders a notice briefly describing such amendment. However, failure to give such notice to all the Holders, or any defect in the notice will not impair or affect the validity of the
amendment. 
  
 SECTION 9.3. Compliance with Trust
Indenture Act. 
  
 Every amendment, waiver or
supplement of this Indenture or the Notes shall comply with the TIA as then in effect; provided, however, that this Section 9.3 shall not of itself require that this Indenture or the Trustee be qualified under the TIA or
constitute any admission or acknowledgment by any party hereto that any such qualification is required prior to the time this Indenture and the Trustee are required by the TIA to be so qualified. 
  
 SECTION 9.4. Revocation and Effect of Consents.

  
 Until an amendment, waiver or supplement becomes effective, a
consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note.
Subject to the following paragraph, any such Holder or subsequent Holder may revoke the consent as to such Holder’s Note or portion of such Note by notice to the Trustee or the Issuer received before the date on which the Trustee receives an
Officers’ Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. An amendment, supplement or waiver becomes effective
upon receipt by 

  

 -121- 









 
the Trustee of such Officers’ Certificate and evidence of consent by the Holders of the requisite percentage in principal amount of outstanding Notes.

  
 The Issuer may, but shall not be obligated to, fix a Record
Date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which Record Date shall be at least 30 days prior to the first solicitation of such consent. If a Record Date is fixed, then notwithstanding
the second sentence of the immediately preceding paragraph, those Persons who were Holders at such Record Date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such
Persons continue to be Holders after such Record Date. No such consent shall be valid or effective for more than 90 days after such Record Date unless consents from Holders of the requisite percentage in principal amount of outstanding Notes
required under this Indenture for the effectiveness of such consents shall have also been given and not revoked within such 90 day period. 
  
 SECTION 9.5. Notation on or Exchange of Notes. 
  
 If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder of such Note to
deliver it to the Trustee. The Trustee may place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for the Note shall issue and
the Trustee shall authenticate a new Note that reflects the changed terms. 
  
 SECTION 9.6. Trustee To Sign Amendments, Etc. 
  
 The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article IX; provided, however, that the Trustee
may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee’s own rights, duties or immunities under this Indenture. In executing such supplement or waiver the Trustee shall be entitled to
receive indemnity reasonably satisfactory to it, and shall be fully protected in relying upon an Opinion of Counsel and an Officers’ Certificate of the Issuer, stating that no event of default shall occur as a result of such amendment,
supplement or waiver and that the execution of any amendment, supplement or waiver authorized pursuant to this Article IX is authorized or permitted by this Indenture, provided the legal counsel delivering such Opinion of Counsel may rely as
to matters of fact on one or more Officers’ Certificates of the Issuer. Such Opinion of Counsel shall not be an expense of the Trustee.

 If any provision of this Indenture limits, qualifies, or conflicts with another provision which is required to be included in this Indenture by the TIA, the required provision shall control; provided, however, that this
Section 11.1 shall not of itself require that this Indenture or the Trustee be qualified under the TIA or constitute any admission or acknowledgment by any party hereto that any such qualification is required prior to the time this Indenture
and the Trustee are required by the TIA to be so qualified.

(5) calendar days after mailing if sent by registered or certified mail, postage prepaid (except that a notice of change of address shall not be deemed to have been given until actually received by the addressee). 
  
 Any notice or communication mailed to a Holder shall be mailed to him by
first class mail or other equivalent means at his address as it appears on the registration books of the Registrar ten (10) days prior to such mailing and shall be sufficiently given to him if so mailed within the time prescribed. 

 
 Any notice or communication shall also be so mailed to any Person
described in TIA § 313(c), to the extent required by the TIA. 
  
 Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders. If a notice or communication is mailed in the manner provided above, it is duly given, whether or not
the addressee receives it. 
  
 SECTION 11.3.
Communications by Holders with Other Holders. 
  
 Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their rights under this Indenture or the Notes. The Issuer, the Trustee, the Registrar and any other Person shall have the
protection of TIA § 312(c). 
  
 SECTION 11.4.
Certificate and Opinion as to Conditions Precedent. 
  
 Upon any request or application by the Issuer and/or any Subsidiary Guarantor to the Trustee to take any action under this Indenture, the Issuer and/or any Subsidiary Guarantor shall furnish to the Trustee:

  
 (1) an Officers’ Certificate, in form
and substance satisfactory to the Trustee, stating that, in the opinion of the signers, all conditions precedent to be performed by the Issuer, if any, provided for in this Indenture relating to the proposed action have been complied with; and

  
 (2) an Opinion of Counsel stating that, in
the opinion of such counsel, all such conditions precedent to be performed by the Issuer, if any, provided for in this Indenture relating to the proposed action have been complied with (which counsel, as to factual matters, may rely on an
Officers’ Certificate). 
  

 -124- 









 SECTION 11.5. Statements Required in Certificate or Opinion.

  
 Each certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture, other than the Officers’ Certificate required by Section 4.6, shall comply with TIA § 314(e) and include: 
  
 (1) a statement that the Person making such certificate or opinion has read such covenant or condition;

  
 (2) a brief statement as to the nature and
scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; 
  
 (3) a statement that, in the opinion of such Person, he has made such examination or investigation as is reasonably necessary to enable
him to express an informed opinion as to whether or not such covenant or condition has been complied with; and 
  
 (4) a statement as to whether or not, in the opinion of each such Person, such condition or covenant has been complied with. 

 
 SECTION 11.6. Rules by Trustee, Paying Agent,
Registrar. 
  
 The Trustee may make
reasonable rules in accordance with the Trustee’s customary practices for action by or at a meeting of Holders. The Paying Agent or Registrar may make reasonable rules for its functions. 
  
 SECTION 11.7. Legal Holidays. 

 
 A “Legal Holiday” used with respect to a particular place
of payment is a Saturday, a Sunday or a day on which commercial banking institutions in New York, New York, Minneapolis, Minnesota or Dallas/Fort Worth, Texas or at such place of payment are authorized or required by law to close. If a payment date
is a Legal Holiday at such place, payment may be made at such place on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period. 
  
 SECTION 11.8. Governing Law. 
  
 THIS INDENTURE , THE NOTES AND THE SUBSIDIARY GUARANTEES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK. Each of the parties hereto agrees to submit to the 

  

 -125- 









 
jurisdiction of the courts of the State of New York in any action or proceeding arising out of or relating to this Indenture. 
  
 SECTION 11.9. No Adverse Interpretation of Other
Agreements. 
  
 This Indenture may not
be used to interpret another indenture, loan or debt agreement of the Issuer or any of its respective Subsidiaries. Any such indenture, loan or debt agreement may not be used to interpret this Indenture. 
  
 SECTION 11.10. No Personal Liability.

  
 No director, officer, employee, incorporator or stockholder of
the Issuer or director, officer, employee, incorporator or stockholder of any Subsidiary Guarantor, as such, shall have any liability for any of the Issuer’s obligations under the Notes, the Guarantors’ obligations under the Subsidiary
Guarantees or this Indenture or any claim based on, in respect of, by reason of, these obligations. Each Holder, by accepting a Note, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the
Notes. The waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy. 
  
 SECTION 11.11. Successors. 
  
 All agreements of the Issuer and the Subsidiary Guarantors in this Indenture, the Notes and the Subsidiary Guarantees shall
bind their successors. All agreements of the Trustee in this Indenture shall bind its successors. 
  
 SECTION 11.12. Duplicate Originals. 
  
 All parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together shall represent the same
agreement. 
  
 SECTION 11.13.
Severability. 
  
 In case any
one or more of the provisions in this Indenture or in the Notes shall be held invalid, illegal or unenforceable, in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the
remaining provisions shall not in any way be affected or impaired thereby, it being intended that all of the provisions hereof shall be enforceable to the full extent permitted by law. 
  
 SECTION 11.14. Independence of Covenants. 
  
 All covenants and agreements in this Indenture and the Notes shall be given
independent effect so that if any particular action or condition is not permitted by any of such 

  

 -126- 









 
covenants, the fact that it would be permitted by an exception to, or otherwise be within the limitations of, another covenant shall not avoid the occurrence
of a Default or an Event of Default if such action is taken or condition exists. 
  
 ARTICLE XII. 
  
 SUBSIDIARY
GUARANTEE OF NOTES 
  
 SECTION 12.1. Unconditional
Subsidiary Guarantee. 
  
 Subject to the
provisions of this Article XII, each Subsidiary Guarantor, if any, hereby, jointly and severally, unconditionally and irrevocably guarantees, on an unsecured senior basis to each Holder of a Note authenticated and delivered by the Trustee and to the
Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer or any other Subsidiary Guarantors to the Holders or the Trustee under this Indenture or
thereunder, that: (a) the principal of, premium and Liquidated Damages, if any, and interest on the Notes shall be duly and punctually paid in full when due, whether at maturity, upon redemption at the option of Holders pursuant to the
provisions of the Notes relating thereto, by acceleration or otherwise, and interest on the overdue principal and (to the extent permitted by law) interest, if any, on the Notes and all other obligations of the Issuer or the Subsidiary Guarantors to
the Holders or the Trustee under this Indenture or thereunder (including amounts due the Trustee under Section 7.7 hereof) and all other obligations shall be promptly paid in full or performed, all in accordance with the terms hereof and
thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal,
whether at maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed, or failing performance of any other obligation of the Issuer to the Holders under this Indenture or under the Notes, for whatever reason, each
Subsidiary Guarantor shall be obligated to pay, or to perform or cause the performance of, the same immediately. An Event of Default under this Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees, and shall
entitle the Holders of Notes to accelerate the obligations of the Subsidiary Guarantors under this Indenture in the same manner and to the same extent as the obligations of the Issuer. 
  
 Each of the Subsidiary Guarantors hereby agrees that its obligations under this Indenture shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, any release
of any other Subsidiary Guarantor, the recovery of any judgment against the Issuer, any action to enforce the same, whether or not a Subsidiary Guarantee is affixed to any particular Note, or 

  

 -127- 









 
any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each of the Subsidiary Guarantors hereby
waives the benefit of diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands
whatsoever and covenants that its Subsidiary Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, this Indenture and this Subsidiary Guarantee. Each Subsidiary Guarantee is a guarantee of
payment and not of collection. If any Holder or the Trustee is required by any court or otherwise to return to the Issuer or to any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the
Issuer or such Subsidiary Guarantor, any amount paid by the Issuer or such Subsidiary Guarantor to the Trustee or such Holder, this Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each
Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other hand, (a) subject to this Article XII, the maturity of the obligations guaranteed hereby may be accelerated as
provided in Article VI hereof for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (b) in the event of any
acceleration of such obligations as provided in Article VI hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantors for the purpose of its Subsidiary Guarantee. 
  
 No stockholder, officer, director, employee, partner or incorporator, past,
present or future, or any Subsidiary Guarantor, as such, shall have any personal liability under the Subsidiary Guarantees by reason of his, her or its status as such stockholder, officer, director, employee, partner or incorporator. 
  
 SECTION 12.2. Limitations on Subsidiary
Guarantees. 
  
 The obligations of each
Subsidiary Guarantor under its Subsidiary Guarantee will be limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities 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 its contribution obligations under this Indenture, will 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. 
  
 SECTION 12.3. Execution and Delivery of Subsidiary Guarantee Notation. 
  
 To further evidence its Subsidiary Guarantee set forth in Section 12.1,
each Subsidiary Guarantor hereby agrees that a notation of such Subsidiary Guarantee, substantially in the form of Exhibit E herein, shall be endorsed on each Note authenticated and 

  

 -128- 









 
delivered by the Trustee. Such notation shall be executed on behalf of each Subsidiary Guarantor by either manual or facsimile signature of one Officer of
each Subsidiary Guarantor, who, in each case, shall have been duly authorized to so execute by all requisite corporate action. The validity and enforceability of any Subsidiary Guarantee shall not be affected by the fact that such notation is not
affixed to any particular Note. 
  
 Each of the Subsidiary
Guarantors hereby agrees that its Subsidiary Guarantee set forth in Section 12.1 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee. 
  
 If an Officer of a Subsidiary Guarantor whose signature is on this Indenture
or on a notation of a Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such notation is endorsed or at any time thereafter, such Subsidiary Guarantor’s Subsidiary Guarantee of such Note
shall be valid nevertheless. 
  
 The delivery of any Note by the
Trustee, after the authentication thereof under this Indenture, shall constitute due delivery of any Subsidiary Guarantee set forth in this Indenture on behalf of each Subsidiary Guarantor. 
  
 SECTION 12.4. Release of a Subsidiary
Guarantor. 
  
 (a) If no
Default exists or would exist under this Indenture, (i) upon the sale or disposition of all of the Capital Stock of a Subsidiary Guarantor by either Issuer or a Restricted Subsidiary of such Issuer in a transaction constituting an Asset
Disposition in accordance with Section 4.16, or upon the consolidation or merger of a Subsidiary Guarantor with or into any Person in compliance with Article V (in each case, other than to either Issuer or an Affiliate of either Issuer or a
Restricted Subsidiary), or (ii) upon the designation of a Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with Section 4.14 or in connection with any Legal Defeasance or satisfaction and discharge of the Notes as provided
in Section 8.1, such Subsidiary Guarantor and each Subsidiary of such Subsidiary Guarantor that is also a Subsidiary Guarantor shall be deemed released from all obligations under this Article XII without any further action required on the part
of the Trustee or any Holder; provided, however, that each such Subsidiary Guarantor is sold or disposed of or designated in accordance with this Indenture. Any Subsidiary Guarantor not so released or the entity surviving such
Subsidiary Guarantor, as applicable, shall remain or be liable under its Subsidiary Guarantee as provided in this Article XII. 
  
 (b) The Trustee shall deliver an appropriate instrument evidencing the release of a Subsidiary Guarantor upon receipt of a request by the
Issuer or such Subsidiary Guarantor accompanied by an Officers’ Certificate and an Opinion of Counsel certifying as to the compliance with this Section 12.4, provided the legal counsel delivering such Opinion of Counsel may rely as
to matters of fact on one or more Officers Certificates of the Issuer. 
  

 -129- 









 The Trustee shall execute any documents reasonably requested by the Issuer or a Subsidiary Guarantor in
order to evidence the release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee endorsed on the Notes and under this Article XII. 
  

Except as set forth in Articles Four and Five and this Section 12.4, nothing contained in this Indenture or in any of the Notes shall prevent any
consolidation or merger of a Subsidiary Guarantor with or into the Issuer or another Subsidiary Guarantor or shall prevent any sale or conveyance of the property of a Subsidiary Guarantor as an entirety or substantially as an entirety to the Issuer
or another Subsidiary Guarantor. 
  
 SECTION 12.5. Waiver
of Subrogation. 
  
 Until this Indenture
is discharged and all of the Notes are discharged and paid in full, each Subsidiary Guarantor hereby irrevocably waives and agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Issuer that arise from the
existence, payment, performance or enforcement of the Issuer’s obligations under the Notes or this Indenture and such Subsidiary Guarantor’s obligations under its Subsidiary Guarantee and this Indenture, in any such instance including,
without limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim or remedy of the Holders against the Issuer, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuer, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of
such claim or other rights. If any amount shall be paid to any Subsidiary Guarantor in violation of the preceding sentence and any amounts owing to the Trustee or the Holders of Notes under the Notes, this Indenture, or any other document or
instrument delivered under or in connection with such agreements or instruments, shall not have been paid in full, such amount shall have been deemed to have been paid to such Subsidiary Guarantor for the benefit of, and held in trust for the
benefit of, the Trustee or the Holders and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be credited and applied to the obligations in favor of the Trustee or the Holders, as the case may be, whether matured or
unmatured, in accordance with the terms of this Indenture. Each Subsidiary Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this
Section 12.5 is knowingly made in contemplation of such benefits. 
  
 SECTION 12.6. Immediate Payment. 
  
 Each Subsidiary Guarantor agrees to make immediate payment to the Trustee on behalf of the Holders of all obligations under the Notes and this Indenture owing or payable to the respective Holders upon receipt of a
demand for payment therefor by the Trustee to such Subsidiary Guarantor in writing. 
  

 -130- 









 SECTION 12.7. No Set-Off. 
  
 Each payment to be made by a Subsidiary Guarantor under this Indenture in
respect of the obligations under the Notes and this Indenture shall be payable in the currency or currencies in which such obligations are denominated, and shall be made without set-off, counterclaim, reduction or diminution of any kind or nature.

  
 SECTION 12.8. Obligations
Absolute. 
  
 The obligations of each
Subsidiary Guarantor under this Indenture are and shall be absolute and unconditional and any monies or amounts expressed to be owing or payable by each Subsidiary Guarantor under this Indenture which may not be recoverable from such Subsidiary
Guarantor on the basis of a Subsidiary Guarantee shall be recoverable from such Subsidiary Guarantor as a primary obligor and principal debtor in respect thereof. 
  
 SECTION 12.9. Obligations Continuing. 
  
 The obligations of each Subsidiary Guarantor under this Indenture shall be
continuing and shall remain in full force and effect until all the obligations have been paid and satisfied in full. Each Subsidiary Guarantor agrees with the Trustee that it will from time to time deliver to the Trustee suitable acknowledgments of
this continued liability under this Indenture and under any other instrument or instruments in such form as counsel to the Trustee may advise and as will prevent any action brought against it in respect of any default under this Indenture being
barred by any statute of limitations now or hereafter in force and, in the event of the failure of a Subsidiary Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and agent of such Subsidiary Guarantor to make, execute and
deliver such written acknowledgment or acknowledgments or other instruments as may from time to time become necessary or advisable, in the judgment of the Trustee on the advice of counsel, to fully maintain and keep in force the liability of such
Subsidiary Guarantor under this Indenture. 
  
 SECTION 12.10.
Obligations Not Reduced. 
  
 The obligations of each Subsidiary Guarantor under this Indenture shall not be satisfied, reduced or discharged solely by the payment of such principal, premium, if any, interest, fees and other monies or amounts as may at any time prior to
discharge of this Indenture pursuant to Article VIII be or become owing or payable under or by virtue of or otherwise in connection with the Notes or this Indenture. 
  
 SECTION 12.11. Obligations Reinstated. 
  
 The obligations of each Subsidiary Guarantor under this Indenture shall
continue to be effective or shall be reinstated, as the case may be, if at any time any payment 

  

 -131- 









 
which would otherwise have reduced the obligations of any Subsidiary Guarantor under this Indenture (whether such payment shall have been made by or on
behalf of the Issuer or by or on behalf of a Subsidiary Guarantor) is rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy, liquidation or reorganization of the Issuer or any Subsidiary Guarantor or otherwise, all as though
such payment had not been made. If demand for, or acceleration of the time for, payment by the Issuer is stayed upon the insolvency, bankruptcy, liquidation or reorganization of the Issuer, all such Indebtedness otherwise subject to demand for
payment or acceleration shall nonetheless be payable by each Subsidiary Guarantor as provided herein. 
  
 SECTION 12.12. Obligations Not Affected. 
  
 The obligations of each Subsidiary Guarantor under this Indenture shall not be affected, impaired or diminished in any way by any act, omission, matter or
thing whatsoever, occurring before, upon or after any demand for payment under this Indenture (and whether or not known or consented to by any Subsidiary Guarantor or any of the Holders) which, but for this provision, might constitute a whole or
partial defense to a claim against any Subsidiary Guarantor under this Indenture or might operate to release or otherwise exonerate any Subsidiary Guarantor from any of its obligations under this Indenture or otherwise affect such obligations,
whether occasioned by default of any of the Holders or otherwise, including, without limitation: 
  
 (a) any limitation of status or power, disability, incapacity or other circumstance relating to the Issuer or any other person, including
any insolvency, bankruptcy, liquidation, reorganization, readjustment, composition, dissolution, winding up or other proceeding involving or affecting the Issuer or any other person; 
  
 (b) any irregularity, defect, unenforceability or invalidity in respect of any Indebtedness or other
obligation of the Issuer or any other person under this Indenture, the Notes or any other document or instrument; 
  
 (c) any failure of the Issuer, whether or not without fault on its part, to perform or comply with any of the provisions of this Indenture
or the Notes, or to give notice thereof to a Subsidiary Guarantor; 
  
 (d) the taking or enforcing or exercising or the refusal or neglect to take or enforce or exercise any right or remedy from or against the Issuer or any other person or their respective assets or the release or
discharge of any such right or remedy; 
  
 (e)
the granting of time, renewals, extensions, compromises, concessions, waivers, releases, discharges and other indulgences to the Issuer or any other Person; 
  

 -132- 









 (f) any change in the time, manner or place of payment of, or in any other term of, any
of the Notes, or any other amendment, variation, supplement, replacement or waiver of, or any consent to departure from, any of the Notes or this Indenture, including, without limitation, any increase or decrease in the principal amount of or
premium, if any, or interest on any of the Notes; 
  
 (g) any change in the ownership, control, name, objects, businesses, assets, capital structure or constitution of the Issuer or a Subsidiary Guarantor; 
  
 (h) any merger or amalgamation of the Issuer or a Subsidiary Guarantor with any Person or Persons;

  
 (i) the occurrence of any change in the laws,
rules, regulations or ordinances of any jurisdiction by any present or future action of any governmental authority or court amending, varying, reducing or otherwise affecting, or purporting to amend, vary, reduce or otherwise affect, any of the
Issuer’s obligations under the Notes or this Indenture or the obligations of a Subsidiary Guarantor under its Subsidiary Guarantee; and 
  
 (j) any other circumstance (other than by complete, irrevocable payment), including release of any other Subsidiary Guarantor pursuant to
Section 12.4, that might otherwise constitute a legal or equitable discharge or defense of the Issuer under this Indenture or the Notes or of a Subsidiary Guarantor in respect of its Subsidiary Guarantee under this Indenture. 
  
 SECTION 12.13. Waiver. 
  
 Without in any way limiting the provisions of Section 12.1 hereof, each
Subsidiary Guarantor hereby waives notice of acceptance hereof, notice of any liability of any Subsidiary Guarantor under this Indenture, notice or proof of reliance by the Holders upon the obligations of any Subsidiary Guarantor under this
Indenture, and diligence, presentment, demand for payment on the Issuer, protest, notice of dishonor or non-payment of any of the Issuer’s obligations, under the notes or this Indenture, or other notice or formalities to the Issuer or any
Subsidiary Guarantor of any kind whatsoever. 
  
 SECTION 12.14.
No Obligation To Take Action Against the Issuer. 
  
 Neither the Trustee nor any other Person shall have any obligation to enforce or exhaust any rights or remedies or to take any other steps under any security for the Issuer’s obligations under the notes or this
Indenture, or against the Issuer or any other Person or any Property of the Issuer or any other Person before the Trustee is entitled to demand payment 

  

 -133- 









 
and performance by any or all Subsidiary Guarantors of their liabilities and obligations under their Subsidiary Guarantees or under this Indenture.

  
 SECTION 12.15. Dealing with the Issuer and
Others. 
  
 The Holders, without
releasing, discharging, limiting or otherwise affecting in whole or in part the obligations and liabilities of any Subsidiary Guarantor under this Indenture and without the consent of or notice to any Subsidiary Guarantor, may 
  
 (a) grant time, renewals, extensions, compromises,
concessions, waivers, releases, discharges and other indulgences to the Issuer or any other Person; 
  
 (b) take or abstain from taking security or collateral from the Issuer or from perfecting security or collateral of the Issuer;

  
 (c) release, discharge, compromise, realize,
enforce or otherwise deal with or do any act or thing in respect of (with or without consideration) any and all collateral, mortgages or other security given by the Issuer or any third party with respect to the obligations or matters contemplated by
this Indenture or the Notes; 
  
 (d) accept
compromises or arrangements from the Issuer; 
  
 (e) apply all monies at any time received from the Issuer or from any security upon such part of the Issuer’s obligations under the Notes and this Indenture as the Holders may see fit or change any such application in whole or in part
from time to time as the Holders may see fit; and 
  
 (f) otherwise deal with, or waive or modify their right to deal with, the Issuer and all other Persons and any security as the Holders or the Trustee may see fit. 
  
 SECTION 12.16. Default and Enforcement. 
  
 If any Subsidiary Guarantor fails to pay in accordance with Section 12.6 hereof, the Trustee may proceed in its name as
trustee under this Indenture in the enforcement of the Subsidiary Guarantee of any such Subsidiary Guarantor and such Subsidiary Guarantor’s obligations thereunder and under this Indenture by any remedy provided by law, whether by legal
proceedings or otherwise, and to recover from such Subsidiary Guarantor its obligations thereunder and under this Indenture. 
  
 SECTION 12.17. Amendment, Etc. 
  

No amendment, modification or waiver of any provision of this Indenture relating to any Subsidiary Guarantor or consent to any departure by any
Subsidiary Guarantor 

  

 -134- 









 
or any other Person from any such provision will in any event be effective unless it is signed by such Subsidiary Guarantor and the Trustee. 
  
 SECTION 12.18. Acknowledgment. 

 
 Each Subsidiary Guarantor hereby acknowledges communication of the terms
of this Indenture and the Notes and consents to and approves of the same. 
  
 SECTION 12.19. Costs and Expenses. 
  
 Each Subsidiary Guarantor shall pay on demand by the Trustee any and all reasonable costs, fees and expenses (including, without limitation, legal fees on
a solicitor and client basis) incurred by the Trustee, its agents, advisors and counsel or any of the Holders in enforcing any of their rights under any Subsidiary Guarantee. 
  
 SECTION 12.20. No Merger or Waiver; Cumulative Remedies. 
  
 No Subsidiary Guarantee shall operate by way of merger of any of the
obligations of a Subsidiary Guarantor under any other agreement, including, without limitation, this Indenture. No failure to exercise and no delay in exercising, on the part of the Trustee or the Holders, any right, remedy, power or privilege under
this Indenture or under this Indenture or the Notes, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege under this Indenture or under this Indenture or the Notes preclude any other or
further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges in the Subsidiary Guarantee and under this Indenture, the Notes and any other document or instrument between a
Subsidiary Guarantor and/or the Issuer and the Trustee are cumulative and not exclusive of any rights, remedies, powers and privilege provided by law. 
  
 SECTION 12.21. Survival of Obligations. 
  
 Without prejudice to the survival of any of the other obligations of each Subsidiary Guarantor under this Indenture, the
obligations of each Subsidiary Guarantor under Section 12.1 shall survive the payment in full of the Issuer’s obligations under the Notes and this Indenture and shall be enforceable against such Subsidiary Guarantor without regard to and
without giving effect to any defense, right of offset or counterclaim available to or which may be asserted by the Issuer or any Subsidiary Guarantor. 
  
 SECTION 12.22. Subsidiary Guarantee in Addition to Other Obligations. 
  
 The obligations of each Subsidiary Guarantor under its Subsidiary Guarantee
and this Indenture are in addition to and not in substitution for any other obligations to the 

  

 -135- 









 
Trustee or to any of the Holders in relation to this Indenture or the Notes and any guarantees or security at any time held by or for the benefit of any of
them. 
  
 SECTION 12.23.
Severability. 
  
 Any provision
of this Article XII which is prohibited or unenforceable in any jurisdiction shall not invalidate the remaining provisions and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision
in any other jurisdiction unless its removal would substantially defeat the basic intent, spirit and purpose of this Indenture and this Article XII. 
  
 SECTION 12.24. Successors and Assigns. 
  
 Each Subsidiary Guarantee shall be binding upon and inure to the benefit of each Subsidiary Guarantor and the Trustee and
the other Holders and their respective successors and permitted assigns, except that no Subsidiary Guarantor may assign any of its obligations under this Indenture or thereunder.

 (REVERSE OF SECURITY) 
  
 8 1/2% Senior Note due 2015 
  
 (1)
Interest. CHAPARRAL ENERGY, INC. (the “Issuer”) promises to pay interest on the principal amount of this Note at the rate per annum shown above and Liquidated Damages, if any, payable pursuant to Section 2(d) of the
Registration Rights Agreement referred to below. Interest on the Notes will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from December 1, 2005. The Issuer will pay interest and Liquidated
Damages, if any, semi-annually in arrears on each Interest Payment Date, commencing June 1, 2006. Interest will be computed on the basis of a 360-day year of twelve 30-day months and, in the case of a partial month, the actual number of days
elapsed. 
  
 The Issuer shall pay interest on overdue principal
and on overdue installments of interest and Liquidated Damages, if any, from time to time on demand at a rate of 0.5 percentage points per annum in excess of the rate borne by the Notes and on overdue installments of interest (without regard to any
applicable grace periods) to the extent lawful. 
  
 (2) Method
of Payment. The Issuer shall pay interest and Liquidated Damages, if any, on the Notes (except defaulted interest) to the Persons who are the registered Holders at the close of business on the Record Date immediately preceding the Interest
Payment Date even if the Notes are canceled on registration of transfer or registration of exchange after such Record Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer shall pay principal, premium and
Liquidated Damages, if any, and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts (“U.S. Legal Tender”). The Issuer may deliver any such interest payment to the
Paying Agent or to a Holder at the Holder’s registered address. 
  
 (3) Paying Agent and Registrar. Initially, Wells Fargo Bank, National Association (the “Trustee”) will act as Paying Agent and Registrar. The Issuer may change any Paying Agent, Registrar or co-Registrar without notice to
the Holders. 
  
 (4) Indenture. The Issuer issued the Notes
under an Indenture, dated as of December 1, 2005 (the “Indenture”), among the Issuer, the Guarantors and the Trustee. This Note is one of a duly authorized issue of Notes of the Issuer designated as its 8  1/2 % Senior Notes due 2015 (the “Notes”). The Notes include any Additional Notes. The Notes and any
Additional Notes are treated as a single class of securities under the Indenture. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Notes 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. Code §§ 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Notes are
subject to all such terms, and Holders of Notes are referred to the Indenture and said 

  

 A-3 









 
Act for a statement of them. The Notes are general unsecured obligations of the Issuer. Payment on each Note is guaranteed on a senior basis by the
Subsidiary Guarantors pursuant to Article 12 of the Indenture. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time in accordance with its terms.

  
 (5) Redemption. (a) Except as described in
subparagraphs (b) and (c) below, the Issuer will not be entitled to redeem the Notes at its option prior to December 1, 2010. The Notes will be redeemable, at the Issuer’s option, in whole at any time or in part from time to
time, on and after December 1, 2010, upon not less than 30 nor more than 60 days’ notice, at the following Redemption Prices (expressed as percentages of the principal amount thereof) if redeemed during the twelve-month period commencing
on December 1 of the years set forth below, plus, in each case, unpaid accrued interest and Liquidated Damages, if any, thereon to the date of redemption:

	 2013 and thereafter
	  	100.000	%

  
 (b) At any time, or
from time to time, on or prior to December 1, 2008, the Issuer may, at its option, use all or a portion of the Net Cash Proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes (including any
Additional Notes) issued under the Indenture at a redemption price equal to 108.500% of the aggregate principal amount of the Notes to be redeemed, plus unpaid accrued interest and Liquidated Damages, if any, thereon to the date of redemption;
provided, that: (1) at least 65% of the aggregate principal amount of Notes issued under the Indenture on the Issue Date remains outstanding immediately after giving effect to any such redemption; and (2) the Issuer makes such
redemption not more than 90 days after the consummation of any such Equity Offering. 
  
 (c) In addition, the Notes may be redeemed, in whole or in part, at any time prior to December 1, 2010 at the option of the Issuer upon not less than 30 nor more than 60 days’ prior notice mailed by
first-class mail to each Holder at its registered address, at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest 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). 
  
 (6) Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder
of Notes to be 

  

 A-4 









 
redeemed at such Holder’s registered address. Notes in denominations larger than $2,000 may be redeemed in part. 
  
 Except as set forth in the Indenture, if monies for the redemption of the
Notes called for redemption shall have been deposited with the Paying Agent for redemption on such Redemption Date, then, unless the Issuer defaults in the payment of such Redemption Price plus accrued interest and Liquidated Damages, if any, the
Notes called for redemption will cease to bear interest from and after such Redemption Date and the only right of the Holders of such Notes will be to receive payment of the Redemption Price plus accrued interest and Liquidated Damages, if any.

  
 (7) Offers to Purchase. Sections 4.15 and 4.16 of the
Indenture provide that, upon the occurrence of a Change of Control (as defined in the Indenture) and after certain Asset Dispositions (as defined in the Indenture), and subject to further limitations contained therein, the Issuer will make an offer
to purchase certain amounts of the Notes in accordance with the procedures set forth in the Indenture. 
  
 (8) Denominations; Transfer; Exchange. The Notes are in registered form, without coupons, and (except Notes issued as payment of Interest) in
denominations of at least $2,000 and integral multiples of $2,000 thereafter. A Holder shall register the transfer of or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Notes or portions
thereof selected for redemption. 
  
 (9) Persons Deemed
Owners. The registered Holder of a Note shall be treated as the owner of it for all purposes. 
  
 (10) Unclaimed Money. If money for the payment of principal or interest remains unclaimed for one year, the Trustee and the Paying Agent will pay
the money back to the Issuer. After that, all liability of the Trustee and such Paying Agent with respect to such money shall cease. 
  
 (11) Discharge Prior to Redemption or Maturity. If the Issuer at any time deposits with the Trustee U.S. Legal Tender or U.S. Government
Obligations sufficient to pay the principal of and interest on the Notes to redemption or maturity and comply with the other provisions of the Indenture relating thereto, the Issuer will be discharged from certain provisions of the Indenture and the
Notes (including certain covenants, but including, under certain circumstances, its obligation to pay the principal of and interest on the Notes but without affecting the rights of the Holders to receive such amounts from such deposits). 

 
 (12) Amendment; Supplement; Waiver. Subject to certain exceptions
set forth in the Indenture, the Indenture or the Notes or the Subsidiary Guarantees may be amended or supplemented with the written consent of the Holders of not less than a majority 

  

 A-5 









 
in aggregate principal amount of the Notes then outstanding, and any past Default or Event of Default or noncompliance with any provision may be waived with
the written consent of the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture or the Notes to, among
other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Notes in addition to or in place of certificated Notes, comply with any requirements of the SEC in order to effect or maintain the qualification of the Indenture
under the TIA or comply with Article V of the Indenture or make any other change that does not adversely affect the rights of any Holder of a Note. 
  
 (13) Restrictive Covenants. The Indenture imposes certain limitations on the ability of the Issuer and its Restricted Subsidiaries to, among other
things, incur additional Indebtedness, make payments in respect of their Capital Stock or certain Indebtedness, make certain Investments, create or incur liens, enter into transactions with Affiliates, create dividend or other payment restrictions
affecting Restricted Subsidiaries, issue Preferred Stock of their Restricted Subsidiaries, and on the ability of the Issuer and its Restricted Subsidiaries to merge or consolidate with any other Person or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of the Issuer’s and its Restricted Subsidiaries’ assets or adopt a plan of liquidation. Such limitations are subject to a number of important qualifications and exceptions. Pursuant to
Section 4.6 of the Indenture, the Issuer must annually report to the Trustee on compliance with such limitations. 
  
 (14) Successors. When a successor assumes, in accordance with the Indenture, all the obligations of its predecessor under the Notes and the
Indenture, the predecessor, subject to certain exceptions, will be released from those obligations. 
  
 (15) Defaults and Remedies. Except as set forth in the Indenture, if an Event of Default occurs and is continuing, the Trustee or the Holders of
not less than 25% in principal amount of Notes then outstanding may declare all the Notes to be due and payable in the manner, at the time and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture or the Notes
except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity reasonably satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders
of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a
Default in payment of principal, premium or Liquidated Damages, if any, or interest when due, for any reason or a Default in compliance with Article V of the Indenture) if it determines that withholding notice is in their interest. 
  
 (16) Trustee Dealings with Issuer. The Trustee under the Indenture, in
its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer, its respective Subsidiaries or its respective Affiliates as if it were not the Trustee.

of the Issuer or any Subsidiary Guarantor, as such, shall have any liability for any obligations of the Issuer or any Subsidiary Guarantor under the Notes, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 
  
 (18) Subsidiary Guarantees. This Note will be entitled to the benefits
of certain Subsidiary Guarantees, if any, made for the benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Subsidiary Guarantors,
