Reference Treasury Dealer Quotations, the average of all such quotations.

 

 

          “Independent Investment Banker” means one of the Reference Treasury Dealers that the Company
appoints to act as the Independent Investment Banker from time to time.

          “Reference Treasury Dealer” means each of Morgan Stanley & Co. Incorporated, Banc of America
Securities LLC, J.P. Morgan Securities Inc., Citigroup Global Markets Inc. and Deutsche Bank
Securities Inc. (each a “Primary Treasury Dealer”) and their respective successors which the
Company specifies from time to time; provided, however, that if any of them ceases
to be a Primary Treasury Dealer, the Company shall substitute therefor another Primary Treasury
Dealer.

          “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer
and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for
the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City
time, on the third Business Day preceding such redemption date.

          “Treasury Rate” means with respect to any redemption date, the rate per annum equal to:
(1) the yield, under the heading which represents the average for the immediately preceding week,
appearing in the most recently published statistical release designated “H.15(519)” or any
successor publication which is published weekly by the Board of Governors of the Federal Reserve
System and which establishes yields on actively traded United States Treasury securities adjusted
to constant maturity under the caption “Treasury Constant Maturities,” for the maturity
corresponding to the Comparable Treasury Issue; provided that, if no maturity is within
three months before or after the Remaining Life of the Securities to be redeemed, yields for the
two published maturities most closely corresponding to the Comparable Treasury Issue shall be
determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a
straight line basis, rounding to the nearest month; or (2) if such release (or any successor
release) is not published during the week preceding the calculation date or does not contain such
yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a
percentage of its principal amount) equal to the Comparable Treasury Price for such redemption
date. The Treasury Rate shall be calculated on the third Business Day preceding the redemption
date.

          Notice of the redemption will be mailed to holders of Securities by first-class mail at least
30 and not more than 60 days prior to the date fixed for redemption. If fewer than all of the
Securities are to be redeemed, the Trustee will select, not more than 60 days prior to the
redemption date, the particular Securities or portions thereof for redemption from the outstanding
Securities not previously called by such method as the Trustee deems fair and appropriate.

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

          In the event of redemption of this Security in part only, a new Security or Securities of this
series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder
hereof upon the cancellation hereof.

          The Indenture contains provisions for defeasance at any time of the entire indebtedness of
this Security or of certain restrictive covenants and Events of Default with respect to this
Security, in each case upon compliance with certain conditions set forth in the Indenture.

          If an Event of Default with respect to Securities of this series shall occur and be
continuing, the principal of the Securities of this series may be declared due and payable in the
manner and with the effect provided for in the Indenture.

          The Indenture contains provisions permitting the Company and the Trustee to modify the
Indenture or any supplemental indenture without the consent of the Holders for one or more of the
following purposes: (1) to evidence the succession of another corporation to the Company; (2) to
add to the covenants of the Company; (3) to add additional events of default for the benefit of
Holders of all or any series of Securities; (4) to add to or change provisions of the Indenture to
allow the issuance of Securities in other forms; (5) to add to, change or eliminate any of the
provisions of the Indenture in respect of one or more series of Securities thereunder, under
certain conditions specified therein; (6) to secure the Securities pursuant to the requirements of
Section 10.05 of the Indenture or otherwise; (7) to establish the form or terms of Securities of
any series as permitted by Sections 2.01 and 3.01 of the Indenture; (8) to evidence the appointment
of a successor Trustee; and (9) to cure any ambiguity, to correct or supplement any provision of
the Indenture which may be defective or inconsistent with any other provision of the Indenture, or
to make any other provisions with respect to matters or questions arising under the Indenture as
shall not adversely affect the interests of the Holders in any material respect.

          The Indenture also permits, with certain exceptions as therein provided, the amendment thereof
and the modification of the rights and obligations of the Company and the rights of the Holders of
the Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of not less than a majority in principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount of the Securities of
each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to
waive compliance by the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the Holder of this
Security shall be conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

          As provided in and subject to the provisions of the Indenture, the Holder of this Security
shall not have the right to institute any proceeding with respect to the

4

 

Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder,
unless such Holder shall have previously given the Trustee written notice of a continuing Event of
Default with respect to the Securities of this series, the Holders of not less than 25% in
principal amount of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and
offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders
of a majority in principal amount of Securities of this series at the time Outstanding a direction
inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days
after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Security for the enforcement of any payment of principal
hereof or any premium or interest hereon on or after the respective due dates expressed herein.

          No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of and any premium and interest on this Security at the times, place and rate, and in
the coin or currency, herein described.

          As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Security is registrable in the Security Register, upon surrender of this Security
for registration of transfer at the office or agency of the Company in any place where the
principal of and any premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing,
and thereupon one or more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

          The Securities of this series are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject
to certain limitations therein set forth, Securities of this series are exchangeable for a like
aggregate principal amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

          No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

          Prior to due presentment of this Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in whose name this
Security is registered as the owner hereof for all purposes, whether or not this Security be
overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

          All terms used in this Security which are defined in the Indenture shall have the meanings

          INDENTURE dated as of February 13, 2009, among DENBURY RESOURCES INC., a Delaware corporation
(the “Company”), certain of the Company’s subsidiaries signatory hereto (each, a
“Subsidiary Guarantor” and, collectively, the “Subsidiary Guarantors”) and THE BANK
OF NEW YORK MELLON TRUST COMPANY, N.A. (the “Trustee”).

          Each party agrees as follows for the benefit of the other parties and for the equal and
ratable benefit of the Holders of the Company’s $420,000,000 aggregate principal amount of 9.75%
Senior Subordinated Notes due 2016 issued on the Issue Date (the “Securities”):

ARTICLE 1

Definitions and Incorporation by Reference

          Section 1.01. Definitions.

          “Additional Assets” means (i) any property or assets (other than Indebtedness and
Capital Stock) in the Oil and Gas Business; (ii) the Capital Stock of a Person that becomes a
Restricted Subsidiary as a result of the acquisition of such Capital Stock by the Company or
another Restricted Subsidiary; or (iii) Capital Stock constituting a minority interest in any
Person that at such time is a Restricted Subsidiary; provided, however, that any
such Restricted Subsidiary described in clauses (ii) or (iii) above is primarily engaged in the Oil
and Gas Business.

          “Additional Securities” means, subject to the Company’s compliance with Section 4.03,
9.75% Senior Subordinated Notes Due 2016 issued from time to time after the Issue Date under the
terms of this Indenture (other than pursuant to Section 2.06, 2.07, 2.09, 3.06 or 9.05 of this
Indenture).

          “Adjusted Consolidated Net Tangible Assets” or “ACNTA” means (without
duplication), as of the date of determination, (a) the sum of (i) the discounted future net revenue
from proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries
calculated in accordance with SEC guidelines before any state or federal income taxes, as estimated
in a reserve report prepared as of the end of the Company’s most recently completed fiscal year,
which reserve report is prepared or reviewed by independent petroleum engineers, as increased by,
as of the date of determination, the discounted future net revenue of (A) estimated proved crude
oil and natural gas reserves of the Company and its Restricted Subsidiaries attributable to
acquisitions consummated since the date of such year-end reserve report, and (B) estimated crude
oil and natural gas reserves of the Company and its Restricted Subsidiaries attributable to
extensions, discoveries and other additions and upward determinations of estimates of proved crude
oil and natural gas reserves (including previously estimated development costs incurred during the
period and the accretion of discount since the prior year end) due to exploration, development or
exploitation, production or other activities which reserves were not reflected in such year-end
reserve report which would, in the case of determinations made pursuant to clauses (A) and (B), in
accordance with standard industry practice, result in such determinations, in each case calculated
in accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report),
and decreased by, as of the date of determination, the discounted future net revenue attributable
to (C) estimated proved

 

2

oil and gas reserves of the Company and its Restricted Subsidiaries reflected in such year-end
reserve report produced or disposed of since the date of such year-end reserve report and (D)
reductions in the estimated crude oil and natural gas reserves of the Company and its Restricted
Subsidiaries reflected in such year-end reserve report since the date of such year-end reserve
report attributable to downward determinations of estimates of proved crude oil and natural gas
reserves due to exploration, development or exploitation, production or other activities conducted
or otherwise occurring since the date of such year-end reserve report which would, in the case of
determinations made pursuant to clauses (C) and (D), in accordance with standard industry practice,
result in such determinations, in each case calculated in accordance with SEC guidelines (utilizing
the prices utilized in such year-end reserve report); 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 Company’s engineers, except that if as a result of such
acquisitions, dispositions, discoveries, extensions or revisions, there is a Material Change which
is an increase, then such increases and decreases in the discounted future net revenue shall be
confirmed in writing by an independent petroleum engineer, (ii) the capitalized costs that are
attributable to crude oil and natural gas properties of the Company and its Restricted Subsidiaries
to which no proved crude oil and natural gas reserves are attributed, based on the Company’s books
and records as of a date no earlier than the date of the Company’s latest annual or quarterly
financial statements, (iii) the Net Working Capital on a date no earlier than the date of the
Company’s latest annual or quarterly financial statements and (iv) the greater of (I) the net book
value on a date no earlier than the date of the Company’s latest annual or quarterly financial
statements and (II) the appraised value, as estimated by independent appraisers, of other tangible
assets of the Company and its Restricted Subsidiaries as of a date no earlier than the date of the
Company’s latest audited financial statements (provided that the Company shall not be
required to obtain such an appraisal of such assets if no such appraisal has been performed), minus
(b) to the extent not otherwise taken into account in the immediately preceding clause (a), the sum
of (i) minority interests, (ii) any natural gas balancing liabilities of the Company and its
Restricted Subsidiaries reflected in the Company’s latest audited financial statements, (iii) the
discounted future net revenue, calculated in accordance with SEC guidelines (utilizing the same
prices utilized in the Company’s year-end reserve report), attributable to reserves subject to
participation interests, overriding royalty interests or other interests of third parties, pursuant
to participation, partnership, vendor financing or other agreements then in effect, or which
otherwise are required to be delivered to third parties, (iv) the discounted future net revenue,
calculated in accordance with SEC guidelines (utilizing the same prices utilized in the Company’s
year-end reserve report), attributable to reserves that are required to be delivered to third
parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with
respect to Volumetric Production Payments on the schedules specified with respect thereto and (v)
the discounted future net revenue, calculated in accordance with SEC guidelines, attributable to
reserves subject to Dollar-Denominated Production Payments that, based on the estimates of
production included in determining the discounted future net revenue specified in the immediately
preceding clause (a)(i)
(utilizing the same prices utilized in the Company’s year-end reserve
report), would be necessary to satisfy fully the obligations of the Company and its Restricted
Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with
respect thereto.

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 Company or a Restricted Subsidiary), (ii) all

Owned Subsidiary, (2) for purposes of Section 4.07 only, a disposition that constitutes a
Restricted Payment permitted by Section 4.05, a disposition of all or substantially all the assets

Control pursuant to clause (iii) of the definition thereof, (3) the sale or transfer (whether or
not in the ordinary course of business) of crude oil and natural gas properties or direct or
indirect interests in real property; provided, however, that at the time of such

abandonment, farm-out, lease or sublease of developed or undeveloped crude oil and natural gas
properties in the ordinary course of business, (5) the trade or exchange by the Company or any

for which such lease has been extended).

          “Average Life” means, as of the date of determination, with respect to any
Indebtedness or Preferred Stock, the quotient obtained by dividing (i) the sum of the products of
the numbers of years from the date of determination to the dates of each successive scheduled

Preferred Stock multiplied by the amount of such payment by (ii) the sum of all such payments.

Act, except that for purposes of this clause (i) such person shall be deemed to have
“beneficial ownership” of all shares that such person has the right to acquire, whether such
right is exercisable immediately or only after the passage of time), directly or indirectly,
of more than 40% of the total voting power of the Voting Stock of the Company (for the
purposes of this clause (i), such person shall be deemed to beneficially own any Voting

consolidation, the securities of the Company that are outstanding immediately prior to

 

5

such transaction and which represent 100% of the aggregate voting power of the Voting
Stock of the Company are changed into or exchanged for cash, securities or property, unless
pursuant to such transaction such securities are changed into or exchanged for, in addition
to any other consideration, securities of the surviving corporation that represent
immediately after such transaction, at least a majority of the aggregate voting power of the
Voting Stock of the surviving corporation.

          “Code” means the Internal Revenue Code of 1986, as amended.

          “Company” means the party named as such in the preamble to this Indenture until a

the aggregate amount of EBITDA for the period of the most recent four consecutive fiscal quarters
ending at least 45 days prior to the date of such determination to (ii) Consolidated Interest
Expense for such four fiscal quarters; provided, however, that (1) if the Company
or any Restricted Subsidiary has Incurred any Indebtedness since the beginning of such period that
remains outstanding or if the transaction giving rise to the need to calculate the Consolidated
Coverage Ratio is an Incurrence of Indebtedness, or both, EBITDA and Consolidated Interest Expense
for such period shall be calculated after giving effect on a pro forma basis to such Indebtedness
as if such Indebtedness had been Incurred on the first day of such period and the discharge of any
other Indebtedness repaid, repurchased, defeased or otherwise discharged with the proceeds of such
new Indebtedness as if such discharge had occurred on the first day of such period, (2) if the
Company or any Restricted Subsidiary has repaid, repurchased, defeased or otherwise discharged any
Indebtedness since the beginning of such period or if any Indebtedness is to be repaid,
repurchased, defeased or otherwise discharged on the date of the transaction giving rise to the
need to calculate the Consolidated Coverage Ratio, EBITDA and Consolidated Interest Expense for
such period shall be calculated on a pro forma basis as if such discharge had occurred on the first
day of such period and as if the Company or such Restricted Subsidiary had not earned the interest
income actually earned during such period in respect of cash or Temporary Cash Investments used to
repay, repurchase, defease or otherwise discharge such Indebtedness, (3) if since the beginning of
such period the Company or any Restricted Subsidiary shall have made any Asset Disposition (other
than an Asset Disposition involving assets having a fair market value of less than the greater of
two and one-half percent (2.5%) of Adjusted Consolidated Net Tangible Assets as of the end of the
Company’s then most recently completed fiscal year and $3.0 million), then EBITDA for such period
shall be reduced by an amount equal to EBITDA (if positive) directly attributable to the assets
which are the subject of such Asset Disposition for such period, or increased by an amount equal to
EBITDA (if negative) directly attributable thereto for such period and Consolidated Interest
Expense for such period shall be reduced by an amount equal to the Consolidated Interest Expense
directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid,
repurchased, defeased or otherwise discharged with respect to the Company and its continuing
Restricted Subsidiaries in connection with such Asset Disposition for such period (or, if the
Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such
period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the
Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after
such sale), (4) if since the

 

6

beginning of such period the Company or any Restricted Subsidiary (by merger or otherwise)
shall have made an Investment in any Restricted Subsidiary (or any Person which becomes a
Restricted Subsidiary) or an acquisition (including by way of lease) of assets, including any
acquisition of assets occurring in connection with a transaction requiring a calculation to be made
hereunder, EBITDA and Consolidated Interest Expense for such period shall be calculated after
giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such
Investment or acquisition occurred on the first day of such period and (5) if since the beginning
of such period any Person (that subsequently became a Restricted Subsidiary or was merged with or
into the Company or any Restricted Subsidiary since the beginning of such period) shall have made
any Asset Disposition, any Investment or acquisition of assets that would have required an
adjustment pursuant to clause (3) or (4) above if made by the Company or a Restricted Subsidiary
during such period, EBITDA and Consolidated Interest Expense for such period shall be calculated
after giving pro forma effect thereto as if such Asset Disposition, Investment or acquisition
occurred on the first day of such period. For purposes of this definition, whenever pro forma
effect is to be given to an acquisition of assets, the amount of income or earnings relating
thereto and the amount of Consolidated Interest Expense associated with any Indebtedness Incurred
in connection therewith, the pro forma calculations shall be determined in good faith by a
responsible financial or accounting Officer of the Company. If any Indebtedness bears a floating
rate of interest and is being given pro forma effect, the interest of such
Indebtedness shall be calculated as if the rate in effect on the date of determination had been the
applicable rate for the entire period (taking into account any Interest Rate Agreement applicable
to such Indebtedness if such Interest Rate Agreement has a remaining term in excess of 12 months).

          “Consolidated Current Liabilities” as of the date of determination means the aggregate
amount of liabilities of the Company and its consolidated Restricted Subsidiaries which would
properly be classified as current liabilities (including taxes accrued as estimated) on a
consolidated balance sheet of the Company and its Restricted Subsidiaries at such date, after
eliminating (i) all intercompany items between the Company and any Restricted Subsidiary and (ii)
all current maturities of long-term Indebtedness, all as determined in accordance with GAAP
consistently applied.

          “Consolidated Interest Expense” means, for any period, the total interest expense of
the Company and its Restricted Subsidiaries for such period, determined on a consolidated basis in
accordance with GAAP, plus, to the extent not included in such total interest expense, and to the
extent incurred by the Company or its Restricted Subsidiaries, without duplication, (i) interest
expense attributable to Capital Lease Obligations and imputed interest with respect to Attributable
Debt, (ii) capitalized interest, (iii) non-cash interest expense, (iv) commissions, discounts and
other fees and charges owed with respect to letters of credit and bankers’ acceptance financing,
(v) net costs (including amortization of fees and up-front payments) associated with interest rate
caps and other interest rate and currency options that, at the time entered into, resulted in the
Company and its Restricted Subsidiaries being net payees as to future payouts under such caps or
options, and interest rate and currency swaps and forwards for which the Company or any of its
Restricted Subsidiaries has paid a premium, (vi) dividends (excluding dividends paid in shares of
Capital Stock which is not Disqualified Stock) in respect of all Disqualified Stock held by Persons
other than the Company or a Wholly Owned Subsidiary, (vii) interest accruing on any Indebtedness of
any other Person to the extent such

 

7

Indebtedness is Guaranteed by the Company or any Restricted Subsidiary or secured by a Lien on
assets of the Company or any Restricted Subsidiary to the extent such Indebtedness constitutes
Indebtedness of the Company or any Restricted Subsidiary (whether or not such Guarantee or Lien is
called upon); provided, however, “Consolidated Interest Expense” shall not
include any (x) amortization of costs relating to original debt issuances other than the
amortization of debt discount related to the issuance of zero coupon securities or other securities
with an original issue price of not more than 90% of the principal thereof, (y) Consolidated
Interest Expense with respect to any Indebtedness Incurred pursuant to Section 4.03(b)(8) and (z)
noncash interest expense Incurred in connection with interest rate caps and other interest rate and
currency options that, at the time entered into, resulted in the Company and its Restricted
Subsidiaries being either neutral or net payors as to future payouts under such caps or options.

          “Consolidated Net Income” means, for any period, the net income of the Company and its
Subsidiaries determined on a consolidated basis in accordance with GAAP; provided,
however, that there shall not be included in such Consolidated Net Income: (i) any net
income of any Person (other than the Company) if such Person is not a Restricted Subsidiary, except
that (A) subject to the exclusion contained in clause (iv) below, the Company’s equity in the net
income of any such Person for such period shall be included in such Consolidated Net Income up to
the aggregate amount of cash actually distributed by such Person during such period to the Company
or a Restricted Subsidiary as a dividend or other distribution (subject, in the case of a dividend
or other distribution paid to a Restricted Subsidiary, to the limitations contained in clause (iii)
below) and (B) the Company’s equity in a net loss of any such Person for such period shall be
included in determining such Consolidated Net Income; (ii) any net income (or loss) of any Person
acquired by the Company or a Subsidiary in a pooling of interests transaction for any period prior
to the date of such acquisition; (iii) any net income of any Restricted Subsidiary (other than a
Subsidiary Guarantor) if such Restricted Subsidiary is subject to restrictions, directly or
indirectly, on the payment of dividends or the making of distributions by such Restricted
Subsidiary, directly or indirectly, to the Company, except that (A) subject to the exclusion
contained in clause (iv) below, the Company’s equity in the net income of any such Restricted
Subsidiary for such period shall be included in such Consolidated Net Income up to the aggregate
amount of cash actually distributed by such Restricted Subsidiary during such period to the Company
or another Restricted Subsidiary as a dividend or other distribution (subject, in the case of a
dividend or other distribution paid to another Restricted Subsidiary, to the limitation contained
in this clause) and (B) the Company’s equity in a net loss of any such Restricted Subsidiary for
such period shall be included in determining such Consolidated Net Income; (iv) any gain or loss
realized upon the sale or other disposition of any assets of the Company or its Subsidiaries
(including pursuant to any sale-and-leaseback arrangement) which is not sold or otherwise disposed
of in the ordinary course of business and any gain or loss realized upon the sale or other
disposition of any Capital Stock of any Person; (v) extraordinary gains or losses; (vi) any
non-cash compensation expense realized for grants of performance shares, stock options or stock
awards to officers, directors and employees of the Company or any of its Restricted Subsidiaries;
(vii) any write-downs of non-current assets; provided, however, that any ceiling
limitation write-downs under SEC guidelines shall be treated as capitalized costs, as if such
write-downs had not occurred; and (viii) the cumulative effect of a change in accounting
principles. Notwithstanding the foregoing, for the purposes of Section 4.05 only, there shall be
excluded from Consolidated Net Income any dividends, repayments of loans or advances or other
transfers of assets from Unrestricted Subsidiaries to the Company or a

 

8

Restricted Subsidiary to the extent such dividends, repayments or transfers increase the
amount of Restricted Payments permitted under Section 4.05(a)(3)(E).

          “Consolidated Net Tangible Assets”, as of any date of determination, means the total
amount of assets (less accumulated depreciation and amortization, allowances for doubtful
receivables, other applicable reserves and other properly deductible items) which would appear on a
balance sheet of the Company and its Restricted Subsidiaries, determined on a consolidated basis in
accordance with GAAP, and after giving effect to purchase accounting and after deducting therefrom
Consolidated Current Liabilities and, to the extent otherwise included, the amounts of: (i)
minority interests in Restricted Subsidiaries held by Persons other than the Company or a
Restricted Subsidiary; (ii) excess of cost over fair value of assets of businesses acquired, as

The Securities

          Section 2.01. Form and Dating. The Securities and the Trustee’s certificate of
authentication shall be substantially in the form of Exhibit A, which is hereby incorporated in and
expressly made a part of this Indenture. The Securities may have notations, legends or
endorsements required by law, stock exchange rule, agreements to which the Company is subject, if
any, or depository procedure or usage (provided that any such notation, legend or endorsement is in
a form acceptable to the Company). Each Security shall be dated the date of its authentication.
The terms of the Securities set forth in Exhibit A are part of the terms of this Indenture.

          Section 2.02. Execution and Authentication. Two Officers shall sign the Securities
for the Company by manual signature.

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

 

26

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

          On the Issue Date, upon receipt of a written order of the Company signed by two Officers of
the Company (a “Company Order”), the Trustee shall authenticate and deliver $420,000,000 of
9.75% Senior Subordinated Notes Due 2016 and, at any time and from time to time thereafter, the
Trustee shall, upon receipt of a Company Order, authenticate and deliver Securities for original
issue in an aggregate principal amount specified in such Company Order; provided that, in
each case, the Trustee shall be entitled to receive an Officers’ Certificate and an Opinion of
Counsel of the Company that it may reasonably request in connection with such authentication of
Securities. Such Company Order shall specify the amount of Securities to be authenticated and the
date on which the original issue of Securities is to be authenticated and, in the case of an
issuance of Additional Securities pursuant to Section 2.13 after the Issue Date, shall certify that
such issuance is in compliance with Section 4.03.

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

          Section 2.03. Registrar and Paying Agent. The Company shall maintain an office or
agency where Securities may be presented for registration of transfer or for exchange, which office
shall maintain the names and addresses of Securityholders (the “Registrar”), and an office
or agency where Securities may be presented for payment (the “Paying Agent”). The
Registrar shall keep a register of the Securities and of their transfer and exchange. The Company
may have one or more co-registrars and one or more additional paying agents. The term “Paying
Agent” includes any additional paying agent.

          The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent
or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The
agreement shall implement the provisions of this Indenture that relate to such agent. The Company
shall notify the Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to
appropriate compensation therefor pursuant to Section 7.07. The Company or any Wholly Owned
Subsidiary incorporated or organized within the United States of America may act as Paying Agent,
Registrar, co-registrar or transfer agent.

          The Company initially appoints the Trustee as Registrar and Paying Agent in connection with
the Securities.

          Section 2.04. Paying Agent To Hold Money in Trust. Prior to 11:00 a.m., New York City
time, on each due date of the principal and interest on any Security, the Company shall deposit
with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due.
The Company shall require each Paying Agent (other than the Trustee) to agree

 

27

in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the
Trustee all money held by the Paying Agent for the payment of principal of or interest on the
Securities and shall notify the Trustee of any default by the Company in making any such payment.
If the Company or a Wholly Owned Subsidiary acts as Paying Agent, it shall segregate the money held
by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by
the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

          Section 2.05. Securityholder Lists. The Trustee shall preserve in as current a form
as is reasonably practicable the most recent list available to it of the names and addresses of
Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in
writing at least five Business Days before each interest payment date and at such other times as
the Trustee may request in writing, a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of Securityholders.

          Section 2.06. Transfer and Exchange. The Securities shall be issued in registered
form and shall be transferable only upon the surrender of a Security for registration of transfer.
When a Security is presented to the Registrar or a co-registrar with a request to register a
transfer, the Registrar shall register the transfer as requested if the requirements of this
Indenture and Section 8-401(a) of the Uniform Commercial Code are met.

          When Securities are presented to the Registrar or a co-registrar with a request to exchange
them for an equal principal amount of Securities of other denominations, the Registrar shall make
the exchange as requested if the same requirements are met.

          Section 2.07. Replacement Securities. If a mutilated Security is surrendered to the
Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or
wrongfully taken, the Company shall issue and the Trustee shall authenticate and deliver a
replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met
and the Holder satisfies any other reasonable requirements of the Trustee. If required by the
Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of
the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar
and any co-registrar from any loss which any of them may suffer if a Security is replaced. The
Company and the Trustee may charge the Holder for their expenses in replacing a Security.

          Every replacement Security is an additional obligation of the Company.

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

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

 

 

 28

          If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a
redemption date or maturity date money sufficient to pay all principal and interest payable on that
date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case
may be, and the Paying Agent is not prohibited from paying such money to the Securityholders on
that date pursuant to the terms of this Indenture, then on and after that date such Securities (or
portions thereof) cease to be outstanding and interest on them ceases to accrue.

          Section 2.09. Temporary Securities. Until definitive Securities are ready for
delivery, the Company may prepare and the Trustee shall authenticate and deliver temporary
Securities. Temporary Securities shall be substantially in the form of definitive Securities but
may have variations that the Company considers appropriate for temporary Securities. Without
unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive
Securities and deliver them in exchange for temporary Securities.

          Section 2.10. Cancellation. The Company at any time may deliver Securities to the
Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange, payment or cancellation.
The Trustee and no one else shall cancel and destroy (subject to the record retention requirements
of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or
cancellation and deliver a certificate of such destruction to the Company unless the Company
directs the Trustee to deliver canceled Securities to the Company. The Company may not issue new
Securities to replace Securities it has redeemed, paid or delivered to the Trustee for
cancellation.

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

          Section 2.12. CUSIP Numbers. The Company in issuing the Securities may use “CUSIP”
numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP”, numbers in notices of
redemption as a convenience to Holders; provided, however, that any such notice may state that no
representation made as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall not be affected by
any defect in or omission of such numbers.

          Section 2.13. Issuance of Additional Securities. The Company shall be entitled,
subject to its compliance with Section 4.03, to issue Additional Securities under this Indenture
which shall have identical terms as the Securities issued on the Issue Date, other than with
respect to the date of issuance and issue price. The Securities issued on the Issue Date and any
Additional Securities shall be treated as a single class for all purposes under this Indenture.

 

29

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

     (1) the aggregate principal amount of such Additional Securities to be authenticated
and delivered pursuant to this Indenture; and

     (2) the issue price, the issue date and the CUSIP number of such Additional Securities;
provided, however, that no Additional Securities may be issued at a price
that would cause such Additional Securities to have “original issue discount” within the
meaning of Section 1273 of the Code.

ARTICLE 3

Redemption

          Section 3.01. Notices to Trustee. If the Company elects to redeem Securities pursuant
to paragraph 5 of the Securities, it shall notify the Trustee in writing of the redemption date,
the principal amount of Securities to be redeemed and the paragraph of the Securities pursuant to
which the redemption will occur.

          The Company shall give each notice to the Trustee provided for in this Section at least 45
days before the redemption date unless the Trustee consents to a shorter period. Such notice shall
be accompanied by an Officers’ Certificate and an Opinion of Counsel from the Company to the effect
that such redemption will comply with the conditions herein.

          Section 3.02. Selection of Securities To Be Redeemed. If fewer than all the
Securities are to be redeemed, the Trustee shall select the Securities to be redeemed pro rata or
by lot or by a method that complies with applicable legal and securities exchange requirements, if
any, and that the Trustee in its sole discretion considers fair and appropriate. The Trustee shall
make the selection from outstanding Securities not previously called for redemption. The Trustee
may select for redemption portions of the principal of Securities that have denominations larger
than $1,000. Securities and portions of them the Trustee selects shall be in amounts of $1,000 or
a whole multiple of $1,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption. The Trustee shall notify
the Company, the Registrar and each Paying Agent promptly of the Securities or portions of
Securities to be redeemed.

          Section 3.03. Notice of Redemption. At least 30 days but not more than 60 days before
a date for redemption of Securities, the Company shall mail a notice of redemption by first-class
mail to each Holder of Securities to be redeemed.

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

     (1) the redemption date;

     (2) the redemption price;

 

30

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

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

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

     (6) that, unless the Company defaults in making such redemption payment or the Paying
Agent is prohibited from making such payment pursuant to the terms of this Indenture,
interest on Securities (or portions thereof) called for redemption ceases to accrue on and
after the redemption date; and

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

          At the Company’s request, the Trustee shall give the notice of redemption in the Company’s
name and at the Company’s expense. In such event, the Company shall provide the Trustee with the
information required by this Section.

          Section 3.04. Effect of Notice of Redemption. Once notice of redemption is mailed,
Securities called for redemption become due and payable on the redemption date and at the
redemption price stated in the notice, subject to any condition or contingency stated therein.
Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in
the notice, plus accrued interest to the redemption date. Failure to give notice or any defect in
the notice to any Holder shall not affect the validity of the notice to any other Holder.

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

          Section 3.06. Securities Redeemed in Part. Upon surrender of a Security that is
redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the
Holder (at the Company’s expense) a new Security equal in principal amount to the unredeemed
portion of the Security surrendered.

ARTICLE 4

this Indenture. Principal and interest shall be considered paid on the date due if on such date
the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all
principal and interest then due and the Trustee or the Paying Agent, as the

 

31

case may be, is not prohibited from paying such money to the Securityholders on that date
pursuant to the terms of this Indenture.

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

          Section 4.02. SEC Reports. Notwithstanding that the Company may not at any time be
subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall
file with the SEC and provide the Trustee and Securityholders with such annual reports and such

Indebtedness if, on the date of such Incurrence and after giving effect thereto, the Consolidated
Coverage Ratio equals or exceeds 2.25 to 1.0.

          (b) Notwithstanding Section 4.03(a), the Company and any Restricted Subsidiary may Incur the
following Indebtedness:

base or other asset-based calculation; provided, however, that in no
event shall such amount exceed the greater of (x) $500 million and (y) 75% of ACNTA
as of the date of such Incurrence;

(2) Indebtedness owed to and held by the Company or a Restricted Subsidiary;
provided, however, that any subsequent issuance or transfer of any
Capital Stock which results in any such Restricted Subsidiary ceasing to be a
Restricted Subsidiary or any subsequent transfer of such Indebtedness (other than to
the Company or another Restricted Subsidiary) shall be deemed, in each case, to
constitute the Incurrence of such Indebtedness by the issuer thereof;

(3) Indebtedness of the Company represented by the Securities (other than any
Additional Securities);

(4) Indebtedness outstanding on the Issue Date (other than Indebtedness described in
paragraph (b) (1), (2) or (3) of this Section 4.03);

(5) Indebtedness of (A) a Restricted Subsidiary Incurred and outstanding on or prior

4.03(a) or Section 4.03(b)(3), (4), (5), this clause (6) or clause (7) below;
provided, however, that to the extent such Refinancing Indebtedness
directly or indirectly Refinances Indebtedness or Preferred Stock of a Restricted
Subsidiary described in Section 4.03(b)(5), such Refinancing Indebtedness shall be
Incurred only by such Restricted Subsidiary or the Company;

(7) Non-recourse Purchase Money Indebtedness;

(8) Indebtedness with respect to Production Payments; provided,
however, that any such Indebtedness shall be Limited Recourse Production
Payments; provided further, however, that the Net Present
Value of the reserves related to such Production Payments shall not exceed 30% of
ACNTA at the time of Incurrence;

(9) Indebtedness consisting of the Subsidiary Guarantees and any Guarantee by a
Subsidiary Guarantor of Indebtedness Incurred by the Company pursuant to paragraphs

obligation for money borrowed);

(13) Indebtedness of the Company or a Restricted Subsidiary Incurred to finance

then outstanding, does not exceed $20 million;

(14) Permitted Marketing Obligations;

(15) In-kind obligations relating to oil and gas balancing positions arising in the
ordinary course of business; and

(16) Indebtedness in an aggregate amount which, together with the amount of all

          (c) Notwithstanding the foregoing, the Company shall not, and shall not permit any Subsidiary
Guarantor to, Incur any Indebtedness pursuant to Section 4.03(b) if the proceeds thereof are used,
directly or indirectly, to Refinance any Subordinated Obligations unless such Indebtedness shall be
subordinated to the Securities or the relevant Subsidiary Guarantee, as the case may be, to at
least the same extent as such Subordinated Obligations.

          (d) For purposes of determining compliance with this Section 4.03, (i) in the event that an
item of Indebtedness meets the criteria of more than one of the types of Indebtedness described in
this Section 4.03, the Company, in its sole discretion, will classify such item of Indebtedness at
the time of Incurrence and only be required to include the amount and type of such Indebtedness in
one of the above clauses of this Section 4.03; provided that items of Indebtedness
outstanding under the Credit Agreement on the Issue Date will be treated as Incurred on the Issue
Date under Section 4.03(b)(1); and (ii) an item of Indebtedness may be divided and classified in
more than one of the types of Indebtedness described in this Section 4.03.

          Section 4.04. Incurrence of Layered Indebtedness. Notwithstanding paragraphs (a) and
(b) of Section 4.03 above, the Company shall not, and the Company shall not permit any Subsidiary
Guarantor to, Incur any Indebtedness if such Indebtedness is subordinate or junior in ranking in
any respect to any Senior Indebtedness of the Company or such Subsidiary Guarantor, as applicable,
unless such Indebtedness is Senior Subordinated Indebtedness or is expressly subordinated in right
of payment to Senior Subordinated Indebtedness of such Person.

          Section 4.05. Limitation on Restricted Payments. (a) The Company shall not, and
shall not permit any Restricted Subsidiary, directly or indirectly, to make a Restricted Payment if
at the time the Company or such Restricted Subsidiary makes such Restricted Payment: (1) a Default

Incur an additional $1.00 of Indebtedness pursuant to Section 4.03(a); or (3) the aggregate amount
of such Restricted Payment and all other Restricted Payments since the Issue Date would exceed the
sum of (without duplication): (A) 50% of the aggregate Consolidated Net Income of the Company
accrued on a cumulative basis commencing on December 31, 2002, and ending on the last day of the
fiscal quarter ending on or immediately preceding the date of such proposed Restricted Payment (or,
if such aggregate Consolidated Net

 

34

Income shall be a deficit, minus 100% of such deficit); (B) the aggregate Net Cash Proceeds
received by the Company from the issuance or sale of its Capital Stock (other than Disqualified
Stock) subsequent to the Issue Date (other than an issuance or sale to a Subsidiary of the Company
and other than an issuance or sale to an employee stock ownership plan or to a trust established by
the Company or any of its Subsidiaries for the benefit of their employees); (C) the aggregate Net
Cash Proceeds received by the Company from the issue or sale subsequent to the Issue Date of its
Capital Stock (other than Disqualified Stock) to an employee stock ownership plan;
provided, however, that if such employee stock ownership plan incurs any
Indebtedness with respect thereto, such aggregate amount shall be limited to an amount equal to any
increase in the Consolidated Net Worth of the Company resulting from principal repayments made by
such employee stock ownership plan with respect to such Indebtedness; (D) the amount by which
Indebtedness of the Company is reduced on the Company’s balance sheet upon the conversion or
exchange (other than by a Subsidiary of the Company) subsequent to the Issue Date, of any
Indebtedness of the Company convertible or exchangeable for Capital Stock (other than Disqualified
Stock) of the Company (less the amount of any cash, or the fair value of any other property,
distributed by the Company upon such conversion or exchange); and (E) an amount equal to the sum of
(i) the net reduction in Investments made by the Company or any Restricted Subsidiary in any Person
resulting from dividends, repayments of loans or advances or other transfers of assets, in each
case to the Company or any Restricted Subsidiary from such Person, and (ii) the portion
(proportionate to the Company’s equity interest in such Subsidiary) of the fair market value of the
net assets of an Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a
Restricted Subsidiary; provided, however, that the foregoing sum shall not exceed,
in the case of any such Person or Unrestricted Subsidiary, the amount of Investments previously
made (and treated as a Restricted Payment) by the Company or any Restricted Subsidiary in such
Person or Unrestricted Subsidiary.

          (b) The provisions of Section 4.05(a) shall not prohibit: (i) dividends paid within 60 days
after the date of declaration thereof if at such date of declaration such dividend would have
complied with this Section 4.05; provided, however, that at the time of payment of
such dividend, no other Default shall have occurred and be continuing (or result therefrom);
provided, further, however, that such dividend shall be included in the
calculation of the amount of Restricted Payments; (ii) any purchase or redemption of Capital Stock
or Subordinated Obligations of the Company made by exchange for, or out of the proceeds of the
substantially concurrent sale of, Capital Stock of the Company (other than Disqualified Stock and
other than Capital Stock issued or sold to a Subsidiary of the Company or an employee stock
ownership plan or to a trust established by the Company or any of its Subsidiaries for the benefit
of their employees); provided, however, that (A) such purchase or redemption shall
be excluded in the calculation of the amount of Restricted Payments and (B) the Net Cash Proceeds
from such sale shall be excluded from the calculation of amounts under Section 4.05(a)(3)(B) (but
only to the extent that such Net Cash Proceeds were used to purchase or redeem such Capital Stock
as provided in this clause (ii)); (iii) any purchase, repurchase, redemption, defeasance or other
acquisition or retirement for value of Subordinated Obligations of the Company made by exchange
for, or out of the proceeds of the substantially concurrent sale of, Subordinated Obligations of
the Company; provided, however, that such purchase, repurchase, redemption,
defeasance or other acquisition or retirement for value shall be excluded in the calculation of the
amount of Restricted Payments; (iv) the repurchase of shares of, or options to purchase shares of,
common stock of the Company or any of its Subsidiaries from employees, former employees,

 

35

directors or former directors of the Company or any of its Subsidiaries (or permitted
transferees of such employees, former employees, directors or former directors), pursuant to the
terms of the agreements (including employment agreements) or plans (or amendments thereto) approved
by the Board of Directors under which such individuals purchase or sell or are granted the option
to purchase or sell, shares of such common stock; provided, however, that the
aggregate amount of such repurchases shall not exceed $2.0 million in any calendar year;
provided, further, however, that such repurchases shall be excluded in the
calculation of the amount of Restricted Payments; (v) loans made to officers, directors or
employees of the Company or any Restricted Subsidiary approved by the Board of Directors (or a duly
authorized officer), the net cash proceeds of which are used solely (A) to purchase common stock of
the Company in connection with a restricted stock or employee stock purchase plan, or to exercise
stock options received pursuant to an employee or director stock option plan or other incentive
plan, in a principal amount not to exceed the exercise price of such stock options or (B) to
refinance loans, together with accrued interest thereon, made pursuant to item (A) of this clause
(v); provided, however, that such loans shall be excluded in the calculation of the
amount of Restricted Payments; or (vi) other Restricted Payments in an aggregate amount not to
exceed $20.0 million; provided, however, that such Restricted Payments shall be
excluded in the calculation of the amount of Restricted Payments.

          Section 4.06. Limitation on Restrictions on Distributions from Restricted
Subsidiaries. The Company shall not, and shall not permit any Restricted Subsidiary to, create
or otherwise cause or permit to exist or become effective any consensual encumbrance or restriction
on the ability of any Restricted Subsidiary (a) to pay dividends or make any other distributions on
its Capital Stock or pay any Indebtedness owed to the Company or a Restricted Subsidiary, (b) to
make any loans or advances to the Company or a Restricted Subsidiary or (c) to transfer any of its
property or assets to the Company or a Restricted Subsidiary, except: (i) any encumbrance or
restriction in the Credit Agreement on the Issue Date or pursuant to any other agreement in effect
on the Issue Date; (ii) any encumbrance or restriction with respect to a Restricted Subsidiary
pursuant to an agreement relating to any Indebtedness Incurred by such Restricted Subsidiary on or
prior to the date on which such Restricted Subsidiary was acquired by the Company (other than
Indebtedness Incurred as consideration in, or to provide all or any portion of the funds or credit
support utilized to consummate, the transaction or series of related transactions pursuant to which
such Restricted Subsidiary became a Restricted Subsidiary or was acquired by the Company) and
outstanding on such date; (iii) any encumbrance or restriction pursuant to an agreement effecting a
Refinancing of Indebtedness Incurred pursuant to an agreement referred to in clause (i) or (ii) of
this covenant or this clause (iii) or contained in any amendment to an agreement referred to in
clause (i) or (ii) of this covenant or this clause (iii); provided, however, that
the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such
refinancing agreement or amendment are no less favorable to the Securityholders than encumbrances
and restrictions with respect to such Restricted Subsidiary contained in such agreements; (iv) any
such encumbrance or restriction consisting of customary nonassignment provisions in leases
governing leasehold interests to the extent such provisions restrict the transfer of the lease or
the property leased thereunder; (v) in the case of clause (c) above, restrictions contained in
security agreements or mortgages securing Indebtedness of a Restricted Subsidiary to the extent
such restrictions restrict the transfer of the property subject to such security agreements or
mortgages; and (vi) any restriction with respect to a Restricted Subsidiary imposed pursuant to an
agreement entered into for the sale or

 

36

disposition of all or substantially all the Capital Stock or assets of such Restricted
Subsidiary pending the closing of such sale or disposition.

          Section 4.07. Limitation on Sales of Assets and Subsidiary Stock. (a) In the event
and to the extent that the Net Available Cash received by the Company or any Restricted Subsidiary
from one or more Asset Dispositions (other than an Asset Disposition referred to in Section
4.07(d)) occurring on or after the Issue Date in any period of 12 consecutive months exceeds 15% of
Adjusted Consolidated Net Tangible Assets as of the beginning of such 12-month period, then the
Company shall (i) within 180 days (in the case of (A) below) or 18 months (in the case of (B)
below) after the date such Net Available Cash so received exceeds such 15% of Adjusted Consolidated
Net Tangible Assets (A) apply an amount equal to such excess Net Available Cash to repay Senior
Indebtedness of the Company or a Subsidiary Guarantor or Indebtedness of a Restricted Subsidiary
that is not a Subsidiary Guarantor, in each case owing to a Person other than the Company or any
Affiliate of the Company or (B) invest an equal amount, or the amount not so applied pursuant to
clause (A), in Additional Assets or Permitted Business Investments or (ii) apply such excess Net
Available Cash (to the extent not applied pursuant to clause (i)) as provided in Section 4.07(b).
The amount of such excess Net Available Cash required to be applied during the applicable period
and not applied as so required by the end of such period shall constitute “Excess
Proceeds.”

          (b) (i) If, as of the first day of any calendar month, the aggregate amount of Excess
Proceeds not theretofore subject to an Excess Proceeds Offer (as defined below) totals at least $10
million, the Company must, not later than the fifteenth Business Day of such month, make an offer
(an “Excess Proceeds Offer”) to purchase from the Holders on a pro rata basis an aggregate
principal amount of Securities equal to the Excess Proceeds (rounded down to the nearest multiple
of $1,000) on such date, at a purchase price equal to 100% of the principal amount of such
Securities, plus, in each case, accrued interest (if any) to the date of purchase (the “Excess
Proceeds Payment”), but, if the terms of any other Senior Subordinated Indebtedness require
that an offer be made for such Senior Subordinated Indebtedness contemporaneously with the Excess
Proceeds Offer, then the Excess Proceeds shall be prorated between the Excess Proceeds Offer and
the offer for such other Senior Subordinated Indebtedness in accordance with the aggregate
outstanding principal amounts (or, in the case of other Senior Subordinated Indebtedness issued
with significant original issue discount, accreted value) of the Securities and such other Senior
Subordinated Indebtedness, and the aggregate principal amount of Securities for which the Excess
Proceeds Offer is made shall be reduced accordingly.

          (ii) The Company shall commence any Excess Proceeds Offer with respect to the Securities by
mailing a notice to the Trustee and each Holder stating: (A) that the Excess Proceeds Offer is
being made pursuant to this Section 4.07 and that all Securities validly tendered will be accepted
for payment on a pro rata basis; (B) the purchase price and the date of purchase (which shall be a
Business Day no earlier than 30 days nor later than 60 days from the date such notice is mailed)
(the “Excess Proceeds Payment Date”); (C) that any Security not tendered will continue to
accrue interest pursuant to its terms; (D) that, unless the Company defaults in the payment of the
Excess Proceeds Payment, any Security accepted for payment pursuant to the Excess Proceeds Offer
shall cease to accrue interest on and after the Excess Proceeds Payment Date; (E) that Holders
electing to have a Security purchased pursuant to the Excess Proceeds Offer will be required to
surrender the Security, together with the form entitled

 

37

“Option of Holder to Elect Purchase” on the reverse side of the Security completed, to the
Paying Agent at the address specified in the notice prior to the close of business on the Business
Day immediately preceding the Excess Proceeds Payment Date; (F) that Holders will be entitled to
withdraw their election if the Paying Agent receives, not later than the close of business on the
third Business Day immediately preceding the Excess Proceeds Payment Date, a telegram, facsimile
transmission or letter setting forth the name of such Holder, the principal amount of Securities
delivered for purchase and a statement that such Holder is withdrawing his election to have such
Securities purchased; and (G) that Holders whose Securities are being purchased only in part will
be issued new Securities equal in principal amount to the unpurchased portion of the Securities
surrendered; provided, however, that each Security purchased and each new Security
issued shall be in a principal amount of $1,000 or integral multiples thereof.

          (iii) On the Excess Proceeds Payment Date, the Company shall (A) accept for payment on a pro
rata basis Securities or portions thereof tendered pursuant to the Excess Proceeds Offer, (B)
deposit with the Paying Agent money sufficient to pay the purchase price of all Securities or
portions thereof so accepted, and (C) deliver, or cause to be delivered, to the Trustee all
Securities or portions thereof so accepted together with an Officers’ Certificate specifying the
Securities or portions thereof so accepted for payment by the Company. The Paying Agent shall
promptly mail to the Holders of Securities so accepted payment in an amount equal to the purchase
price, and the Trustee shall promptly authenticate and mail to such Holders a new Security equal in
principal amount to any unpurchased portion of the Security surrendered; provided,
however, that each Security purchased and each new Security issued shall be in a principal
amount of $1,000 or integral multiples thereof. The Company will publicly announce the results of
the Excess Proceeds Offer as soon as practicable after the Excess Proceeds Payment Date. For
purposes of this Section 4.07, the Trustee shall act as the Paying Agent.

          (c) In the event of the transfer of substantially all (but not all) the property and assets of
the Company as an entirety to a Person in a transaction permitted by Section 5.01, the Successor
Company shall be deemed to have sold the properties and assets of the Company not so transferred
for purposes of this Section 4.07, and shall comply with the provisions of this Section 4.07 with
respect to such deemed sale as if it were an Asset Disposition and the Successor Company shall be
deemed to have received Net Available Cash in an amount equal to the fair market value (as
determined in good faith by the Board of Directors) of the properties and assets not so transferred
or sold.

          (d) In the event of an Asset Disposition by the Company or any Restricted Subsidiary that
consists of a sale of hydrocarbons and results in Production Payments, the Company or such
Restricted Subsidiary shall apply an amount equal to the Net Available Cash received by the Company
or such Restricted Subsidiary to (i) reduce Senior Indebtedness of the Company or a Subsidiary
Guarantor or Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor, in each
case owing to a Person other than the Company or any Affiliate of the Company, within 180 days
after the date such Net Available Cash is so received, or (ii) invest in Additional Assets or
Permitted Business Investments within 18 months after the date such Net Available Cash is so
received.

deemed to have breached its obligations under this Section 4.07 by virtue thereof.

          Section 4.08. Limitation on Affiliate Transactions. (a) The Company shall not, and
shall not permit any Restricted Subsidiary to, enter into or permit to exist any transaction
(including the purchase, sale, lease or exchange of any property, employee compensation
arrangements or the rendering of any service) with any Affiliate of the Company (an “Affiliate
Transaction”) unless the terms thereof (1) are no less favorable to the Company or such
Restricted Subsidiary than those that could be obtained 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 amount in excess of $15.0 million, are set forth in writing and have been approved by
the Board of Directors, including a majority of the members of the Board of Directors having no
personal stake in such Affiliate Transaction, and (3) if such Affiliate Transaction involves an
amount in excess of $25.0 million, have been determined by a nationally recognized investment
banking firm or other qualified independent appraiser to be fair, from a financial standpoint, to
the Company and its Restricted Subsidiaries.

          (b) The provisions of Section 4.08(a) shall not prohibit (i) any sale of hydrocarbons or other
mineral products to an Affiliate of the Company or the entering into or performance of Oil and Gas
Hedging Contracts, gas gathering, transportation or processing contracts or oil or natural gas
marketing or exchange contracts with an Affiliate of the Company, in each case, in the ordinary
course of business, so long as the terms of any such transaction are approved by a majority of the
members of the Board of Directors who are disinterested with respect to such transaction, (ii) the
sale to an Affiliate of the Company of Capital Stock of the Company that does not constitute
Disqualified Stock, and the sale to an Affiliate of the Company of Indebtedness (including
Disqualified Stock) of the Company in connection with an offering of such Indebtedness in a market
transaction and on terms substantially identical to those of other purchasers in such market
transaction, (iii) transactions contemplated by any employment agreement or other compensation plan
or arrangement existing on the Issue Date or thereafter entered into by the Company or any of its
Restricted Subsidiaries in the ordinary course of business, (iv) the payment of reasonable fees to
directors of the Company and its Restricted Subsidiaries who are not employees of the Company or
any Restricted Subsidiary, (v) transactions between or among the Company and its Restricted
Subsidiaries, (vi) transactions between the Company or any of its Restricted Subsidiaries and
Persons that are controlled (as defined in the definition of “Affiliate”) by the Company
(an “Unrestricted Affiliate”); provided that no other Person that controls (as so
defined) or is under common control (as so defined) with the Company holds any Investments in such
Unrestricted Affiliate; (vii) Restricted Payments that are permitted by the provisions of Section
4.05; (viii) loans or advances to employees in the ordinary course of business and approved by the
Company’s Board of Directors in an aggregate principal amount not to exceed $2.5 million
outstanding at any one time; and (ix) purchase and supply transactions with GEL or its Affiliates
in the ordinary course of business consistent with past practice.

          Section 4.09. Change of Control. (a) Upon the occurrence of a Change of Control,
each Holder shall have the right to require that the Company purchase such Holder’s Securities at a
purchase price in cash equal to 101% of the principal amount thereof plus accrued and unpaid
interest, if any, to the date of purchase (subject to the right of Holders of record on the
relevant record date to receive interest on the relevant interest payment date), in accordance with
the terms contemplated in Section 4.09(b). In the event that at the time of such Change of Control
the terms of the Indebtedness under the Credit Agreement restrict or prohibit the purchase of
Securities pursuant to this Section, then prior to the mailing of the notice to Holders provided
for in Section 4.09(b) below, but in any event within 30 days following any Change of Control, the
Company shall (i) repay in full the Indebtedness under the Credit Agreement or (ii) obtain the
requisite consent under the agreements governing the Indebtedness under the Credit Agreement to
permit the purchase of the Securities as provided for in Section 4.09(b).

          (b) Within 30 days following a Change of Control, the Company shall mail a notice 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 Company to purchase such Holder’s Securities at a purchase
price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest, if
any, to the date of purchase (subject to the right of Holders of record on the relevant record date
to receive interest on the relevant interest payment date); (2) the circumstances and relevant
facts regarding such Change of Control (including information with respect to pro forma historical
income, cash flow and capitalization, in each case after giving effect to such Change of Control);
(3) the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date
such notice is mailed); and (4) the instructions determined by the Company, consistent with this
Section 4.09, that a Holder must follow in order to have its Securities purchased.

          (c) Holders electing to have a Security purchased will be required to surrender the Security,
with an appropriate form duly completed, to the Company at the address specified in the notice at
least three Business Days prior to the purchase date. Holders will be entitled to withdraw their
election if the Trustee or the Company receives not later than one Business Day prior to the
purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the
Holder, the principal amount of the Security which was delivered for purchase by the Holder and a
statement that such Holder is withdrawing his election to have such Security purchased.

          (d) On the purchase date, all Securities purchased by the Company under this Section shall be
delivered to the Trustee for cancelation, and the Company shall pay the purchase price plus accrued
and unpaid interest, if any, to the Holders entitled thereto.

          (e) The Company shall comply, to the extent applicable, with the requirements of Section 14(e)
of the Exchange Act and any other securities laws or regulations in connection with the purchase of
Securities pursuant to this Section 4.09. To the extent that the provisions of any securities laws
or regulations conflict with the provisions of this Section 4.09, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have breached its obligations
under this Section 4.09 by virtue thereof.

 

40

          (f) The Company will not be required to make an offer to purchase Securities as a result of a
Change of Control pursuant to this Section 4.09 if a third party (i) makes such offer in the
manner, at the times and otherwise in compliance with the requirements set forth in Section 4.09(b)
and (ii) purchases all Securities validly tendered and not withdrawn under such an offer.

          Section 4.10. Limitation on Liens. The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, enter into, create, incur, assume or suffer to
exist any Lien on or with respect to any property of the Company or such Restricted Subsidiary,
whether owned on the Issue Date or acquired after the Issue Date, or any interest therein or any
income or profits therefrom, unless the Securities or any Subsidiary Guarantee of such Restricted
Subsidiary, as applicable, are secured equally and ratably with (or prior to) any and all other
Indebtedness secured by such Lien, except that the Company and its Restricted Subsidiaries may
enter into, create, incur, assume or suffer to exist Permitted Liens and Liens securing Senior
Indebtedness.

          Section 4.11. Compliance Certificate. The Company shall deliver to the Trustee within
120 days after the end of each fiscal year of the Company an Officers’ Certificate stating that in
the course of the performance by the signers of their duties as Officers of the Company they would
normally have knowledge of any Default and whether or not the signers know of any Default that
occurred during such fiscal year. If they do, the certificate shall describe the Default, its
status and what action the Company is taking or proposes to take with respect thereto. The Company
also shall comply with TIA § 314(a)(4).

          Section 4.12. Further Instruments and Acts. Upon request of the Trustee, the Company
will execute and deliver such further instruments and do such further acts as may be reasonably
necessary or proper to carry out more effectively the purpose of this Indenture.

          Section 4.13. Future Subsidiary Guarantors. The Company shall cause each Restricted
Subsidiary that represents at least 10% of the book assets of, or 10% of the ACNTA of the Company
and its Restricted Subsidiaries, taken as a whole, and that has an aggregate of $15.0 million or
more of Indebtedness and Preferred Stock outstanding at any time to promptly Guarantee the
Securities pursuant to a Supplemental Indenture substantially in the form attached hereto as
Exhibit 1.

          Section 5.01. When Company May Merge or Transfer Assets. The Company shall not
consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a
series of related transactions, all or substantially all the assets of the Company and its
Restricted Subsidiaries, taken as a whole, to, any Person, unless:

     (ii) immediately after giving effect to such transaction (and treating any Indebtedness
which becomes an obligation of the Successor Company or any Restricted Subsidiary as a
result of such transaction as having been Incurred by the Successor Company or any
Subsidiary as a result of such transaction as having been Incurred by such Successor Company
or such Subsidiary at the time of such transaction), no Default shall have occurred and be
continuing;

assets of the Company and its Restricted Subsidiaries, taken as a whole, such assets shall
have been so conveyed, transferred or leased as an entirety or virtually as an entirety to
one Person; and

     (vi) the Company shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that such consolidation, merger

or transfer and such supplemental indenture (if any) comply with this Indenture;

provided, however, that clauses (iii) and (iv) shall not be applicable to any such
transaction solely between the Company and any Restricted Subsidiary.

          The Successor Company shall be the successor to the Company and shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under this Indenture, and
the predecessor Company, except in the case of a lease, shall be released from the obligation to

expressly assume, by executing a Guarantee Agreement, all the obligations of such Subsidiary, if

ARTICLE 6

Defaults and Remedies

     Section 6.01. Events of Default. An “Event of Default” occurs if:

     (1) the Company defaults in any payment of interest on any Security when the same
becomes due and payable, whether or not such payment shall be prohibited by Article 10, and
such default continues for a period of 30 consecutive days;

     (2) the Company (i) defaults in the payment of the principal of any Security when the
same becomes due and payable at its Stated Maturity, upon optional redemption, upon required
purchase, upon declaration of acceleration or otherwise, whether or not such payment shall

pursuant to this Indenture or the Securities, whether or not such redemption or purchase
shall be prohibited by Article 10;

     (3) the Company fails to comply with Section 5.01;

     (4) the Company fails to comply with Section 4.02, 4.03, 4.04, 4.05, 4.06, 4.07 (other

and such failure continues for 30 consecutive days after the notice specified below;

     (5) the Company fails to comply with any of its agreements contained in the Securities

     (6) Indebtedness of the Company (other than Limited Recourse Production Payments and
Non-recourse Purchase Money Indebtedness) is not paid within any applicable grace period
after final maturity or the maturity of such Indebtedness is accelerated by the holders
thereof because of a default (and such acceleration is not rescinded or annulled) and the
total amount of such Indebtedness unpaid or accelerated exceeds $10.0 million;

     (7) the Company or any Significant Subsidiary pursuant to or within the meaning of any
Bankruptcy Law:

 

43

     (A) commences a voluntary case;

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

     (C) consents to the appointment of a Custodian of it or for any substantial
part of its property; or

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

or takes any comparable action under any foreign laws relating to insolvency;

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

     (A) is for relief against the Company or any Significant Subsidiary in an
involuntary case;

     (B) appoints a Custodian of the Company or any Significant Subsidiary or for
any substantial part of its property; or

     (C) orders the winding up or liquidation of the Company or any Significant
Subsidiary;

or any similar relief is granted under any foreign laws and the order or decree
remains unstayed and in effect for 60 days;

     (9) any judgment or decree for the payment of money in an uninsured or unindemnified
amount in excess of $10.0 million or its foreign currency equivalent at the time is rendered
against the Company or a Significant Subsidiary and is not discharged and either (A) an
enforcement proceeding has been commenced by any creditor upon such judgment or decree or
(B) there is a period of 60 days following the entry of such judgment or decree during which
such judgment or decree is not discharged, waived, bonded or the execution thereof stayed,
in either case 10 days after the notice specified below; or

     (10) any Subsidiary Guarantee ceases or otherwise fails to be in full force and effect
(other than in accordance with the terms of such Subsidiary Guarantee) or any Subsidiary
Guarantor denies or disaffirms its obligations under its Subsidiary Guarantee if such
default continues for a period of 10 days after the notice specified below.

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

 

44

          The term “Bankruptcy Law” means Title 11, United States Code, or any similar
Federal or state law for the relief of debtors. The term “Custodian” means any receiver,
trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

          A Default under clause (4), (5), (9) or (10) is not an Event of Default until the Trustee or
the Holders of at least 25% in principal amount of the Securities notify the Company of the Default
and the Company does not cure such Default within the time specified after receipt of such notice.
Such notice must specify the Default, demand that it be remedied and state that such notice is a
“Notice of Default”.

          The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written
notice, in the form of an Officers’ Certificate, of any Event of Default under clause (3) or (6)
and any event which with the giving of notice or the lapse of time would become an Event of Default
under clause (4), (5), (9) or (10), describing its status and what action the Company is taking or
proposes to take with respect thereto. The Trustee shall not be deemed to have knowledge of any
Default or Event of Default unless one of its Trust Officers receives written notice thereof from
the Company or any of the Holders.

          Section 6.02. Acceleration. If an Event of Default (other than an Event of Default
specified in Section 6.01(7) or (8) with respect to the Company) occurs and is continuing, the
Trustee by written notice to the Company, or the Holders of at least 25% in principal amount of the
outstanding Securities by written notice to the Company and the Trustee, may declare the principal
of and accrued but unpaid interest on all the Securities to be due and payable. Upon such a
declaration, such principal and interest shall be due and payable immediately. If an Event of
Default specified in Section 6.01(7) or (8) with respect to the Company occurs and is continuing,
the principal of and interest on all the Securities shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of the Trustee or any
Securityholders. The Holders of a majority in principal amount of the outstanding Securities by
written notice to the Trustee may rescind any such acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing Events of Default
have been cured or waived except nonpayment of principal or interest that has become due solely
because of acceleration. No such rescission shall affect any subsequent Default or impair any
right consequent thereto.

          Section 6.03. Other Remedies. If an Event of Default occurs and is continuing, the
Trustee may pursue any available remedy to collect the payment of principal of or interest on the
Securities or to enforce the performance of any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any of the Securities or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any
Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair
the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy
is exclusive of any other remedy. All available remedies are cumulative.

          Section 6.04. Waiver of Past Defaults. The Holders of a majority in principal amount
of the Securities by written notice to the Trustee may waive an existing or past Default

 

45

and its consequences except (i) a Default in the payment of the principal of or interest on a
Security or (ii) a Default in respect of a provision that under Section 9.02 cannot be amended
without the consent of each Securityholder affected. When a Default is waived, it is deemed cured,
but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

          Section 6.05. Control by Majority. The Holders of a majority in principal amount of
the outstanding Securities may direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee.
The Trustee, however, may refuse to follow any direction that conflicts with law or this Indenture
or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of
other Securityholders or would involve the Trustee in personal liability; provided,
however, that the Trustee may take any other action deemed proper by the Trustee that is
not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be
entitled to be furnished with indemnification satisfactory to it in its sole discretion against all
losses and expenses caused by taking or not taking such action.

          Section 6.06. Limitation on Suits. A Securityholder may not pursue any remedy with
respect to this Indenture or the Securities unless:

     (1) the Holder gives to the Trustee written notice stating that an Event of Default is
continuing;

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

     (3) such Holder or Holders furnish, if required by the Trustee, to the Trustee
reasonable security or indemnity against any loss, liability or expense;

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

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

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

          Section 6.07. Rights of Holders To Receive Payment. Notwithstanding any other
provision of this Indenture, the right of any Holder to receive payment of principal of, premium
(if any) or interest on the Securities held by such Holder, on or after the respective due dates
expressed in the Securities, or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of such Holder.

          Section 6.08. Collection Suit by Trustee. If an Event of Default specified in Section
6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as
trustee of an express trust against the Company for the whole amount then due and

 

46

owing (together with interest on any unpaid interest to the extent lawful) and the amounts
provided for in Section 7.07.

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

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

     FIRST: to the Trustee for amounts due under Section 7.07;

     SECOND: to holders of Senior Indebtedness to the extent required by Article 10 or 12;

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

     FOURTH: to the Company.

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

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

          Section 6.12. Waiver of Stay or Extension Laws. The Company (to the extent it may
lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this Indenture; and the
Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or

 

47

advantage of any such law, and shall not hinder, delay or impede the execution of any power
herein granted to the Trustee, but shall suffer and permit the execution of every such power as
though no such law had been enacted.

ARTICLE 7

Trustee

          Section 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is
continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use
the same degree of care and skill in their exercise as a prudent Person would exercise or use under
the circumstances in the conduct of such Person’s own affairs.

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

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

     (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed therein, upon
certificates or opinions furnished to the Trustee and conforming to the requirements of this
Indenture. However, the Trustee shall examine such certificates and opinions to determine
whether or not they conform to the requirements of this Indenture.

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

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

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

     (3) the Trustee shall not be liable with respect to any action it takes or omits to
take in good faith in accordance with a direction received by it pursuant to Section 6.05.

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

          (e) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company.

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

 

48

          (g) No provision of this Indenture shall require the Trustee to advance, expend or risk its
own funds or otherwise incur financial liability in the performance of any of its duties hereunder
or in the exercise of any of its rights or powers. The Trustee, however, may so advance or expend
its own funds if, in its own reasonable judgment, the Trustee believes that repayment of such funds
or adequate indemnity against such risk or liability has been reasonably assured to it.

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

          (i) Notwithstanding anything to the contrary herein, the Trustee shall have no duty to review
the reports and information documents required to be provided by Section 4.02 for the purposes of
determining compliance with any provisions of this Indenture.

          Section 7.02. Rights of Trustee. (a) The Trustee may rely on any document believed
by it to be genuine and to have been signed or presented by the proper person. The Trustee need
not investigate any fact or matter stated in the document.

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

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

          (d) The Trustee shall not be liable for any action it takes or omits to take in good faith
which it believes to be authorized or within its rights or powers; provided,
however, that the Trustee’s conduct does not constitute wilful misconduct or negligence.

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

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

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

 

49

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

          Section 7.05. Notice of Defaults. If a Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to each Securityholder notice of the Default within 90
days after it occurs. Except in the case of a Default in payment of principal of or interest on
any Security (including payments pursuant to the mandatory redemption provisions of such Security,
if any), the Trustee may withhold the notice if and so long as the Trust Officer responsible for
administering this Indenture and the Securities in good faith determines that withholding notice is
not opposed to the interests of Securityholders.

          Section 7.06. Reports by Trustee to Holders. Within sixty (60) days after February 13
of each year, beginning with February 13, 2010, the Trustee shall mail to each Securityholder a
brief report dated as of February 13 of such year, that complies with TIA § 313(a). The Trustee
also shall comply with TIA § 313(b).

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

          Section 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from
time to time reasonable compensation for its services, including extraordinary services such as
default administration. The Trustee’s compensation shall not be limited by any law on compensation
of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all
reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in
addition to the compensation for its services. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants
and experts. The Company shall indemnify the Trustee against any and all loss, liability or
expense (including attorneys’ fees) arising out of its acceptance of this trust or incurred by it
in connection with the administration of this trust and the performance of its duties hereunder,
including the costs and expenses of enforcing this Indenture against the Company (including under
Section 7.07). The Trustee shall notify the Company promptly of any claim (whether asserted by any
Securityholder or the Company) for which it may seek indemnity. Failure by the Trustee to so
notify the Company shall not relieve the Company of its obligations hereunder. The Company shall
defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and
expenses of such counsel. The Company need not reimburse any expense or indemnify against any
loss, liability or expense incurred by the Trustee through the Trustee’s own wilful misconduct,
negligence or bad faith.

          To secure the Company’s payment obligations in this Section, the Trustee shall have a lien
prior to the Securities on all money or property held or collected by the Trustee other than money
or property held in trust to pay principal of and interest on particular Securities.

 

50

          The Company’s payment obligations pursuant to this Section shall survive the resignation or
removal of the Trustee and the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.01(7) or (8) with respect to the Company, the
expenses are intended to constitute expenses of administration under the Bankruptcy Law.

          Section 7.08. Replacement of Trustee. The Trustee may resign at any time by so
notifying the Company. The Holders of a majority in principal amount outstanding of the Securities
may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. A holder
may petition a court of competent jurisdiction to remove the Trustee in the manner and under the
circumstances contemplated by TIA § 310(b)(iii). The Company shall remove the Trustee if:

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

     (2) the Trustee is adjudged bankrupt or insolvent;

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

     (4) the Trustee otherwise becomes incapable of acting.

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

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

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

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

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

 

51

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

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

          Section 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy
the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at
least $50.0 million as set forth in its most recent annual report of condition. The Trustee shall
comply with TIA § 310(b); provided, however, that there shall be excluded from the
operation of TIA § 310(b)(1) any indenture or indentures under which other securities or
certificates of interest or participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in TIA § 310(b)(1) are met.

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

ARTICLE 8

Discharge of Indenture; Defeasance

          Section 8.01. Discharge of Liability on Securities; Defeasance. (a) When (i) the
Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant
to Section 2.07) for cancelation or (ii) all outstanding Securities have become due and payable,
whether at maturity or as a result of the mailing of a notice of redemption pursuant to Article 3
hereof and the Company irrevocably deposits with the Trustee funds sufficient to pay at maturity or
upon redemption all outstanding Securities, including interest thereon to maturity or such
redemption date (other than Securities replaced pursuant to Section 2.07), and if in either case
the Company pays all other sums payable hereunder by the Company, then this Indenture shall,
subject to Section 8.01(c), cease to be of further effect. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’
Certificate and an Opinion of Counsel and at the cost and expense of the Company.

          (b) Subject to Sections 8.01(c) and 8.02, the Company at any time may terminate (i) all its
obligations under the Securities and this Indenture (“legal defeasance option”) or (ii) its
obligations under Sections 4.02, 4.03, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11 and 4.13

 

52

and the operation of Sections 6.01(4), 6.01(6), 6.01(7) (but only with respect to Significant
Subsidiaries), 6.01(8) (but only with respect to Significant Subsidiaries), 6.01(9) and 6.01(10)
and its obligations under Sections 5.01(iii), (iv) and (v) and under Section 5.02 (“covenant
defeasance option”). The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option.

          If the Company exercises its legal defeasance option, payment of the Securities may not be
accelerated because of an Event of Default. If the Company exercises its covenant defeasance
option, payment of the Securities may not be accelerated because of an Event of Default specified
in Section 6.01(4), 6.01(6), 6.01(7) (but only with respect to Significant Subsidiaries), 6.01(8)
(but only with respect to Significant Subsidiaries), 6.01(9) or 6.01(10) or because of the failure
of the Company to comply with Section 5.01(iii), (iv) or (v) or with Section 5.02. If the Company
exercises its legal defeasance option or its covenant defeasance option, each Subsidiary Guarantor
will be released from all its obligations with respect to its Subsidiary Guarantee.

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

          (c) Notwithstanding clauses (a) and (b) above, the Company’s obligations in Sections 2.03,
2.04, 2.05, 2.07, 7.07, 7.08 and this Article 8 shall survive until the Securities have been paid
in full. Thereafter, the Company’s obligations in Sections 7.07, 8.04 and 8.05 shall survive.

          Section 8.02. Conditions to Defeasance. The Company may exercise its legal defeasance
option or its covenant defeasance option only if:

     (1) the Company irrevocably deposits in trust with the Trustee money or U.S.
Government Obligations for the payment of principal and interest on the Securities to
maturity or redemption, as the case may be;

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

     (3) 123 days pass after the deposit is made and during the 123-day period no Default
specified in Section 6.01(7) or (8) with respect to the Company occurs which is continuing
at the end of the period;

     (4) the deposit does not constitute a default under any other agreement binding on the
Company and is not prohibited by Article 10;

 

53

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

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

     (7) in the case of the covenant defeasance option, the Company shall have delivered to
the Trustee an Opinion of Counsel to the effect that the Securityholders 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; and

     (8) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent to the defeasance and discharge of the
Securities as contemplated by this Article 8 have been complied with.

          Before or after a deposit, the Company may make arrangements satisfactory to the Trustee for
the redemption of Securities at a future date in accordance with Article 3.

          Section 8.03. Application of Trust Money. The Trustee shall hold in trust money or
U.S. Government Obligations deposited with it pursuant to this Article 8. It shall apply the
deposited money and the money from U.S. Government Obligations through the Paying Agent and in
accordance with this Indenture to the payment of principal of and interest on the Securities.
Money and securities so held in trust are not subject to Article 10.

          Section 8.04. Repayment to Company. The Trustee and the Paying Agent shall promptly
turn over to the Company upon request any money or securities held by them at any time which, in
the opinion of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the amount thereof that
would then be required for the Company to exercise its legal defeasance option or its covenant
defeasance option pursuant to this Article 8.

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

          Section 8.05. Indemnity for Government Obligations. The Company shall pay and shall
indemnify the Trustee against any tax, fee or other charge imposed on or assessed

 

54

against deposited U.S. Government Obligations or the principal and interest received on such
U.S. Government Obligations.

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

ARTICLE 9

Amendments

          Section 9.01. Without Consent of Holders. The Company, the Subsidiary Guarantors and
the Trustee may amend this Indenture or the Securities without notice to or consent of any
Securityholder:

     (1) to cure any ambiguity, omission, defect or inconsistency;

     (2) to comply with Article 5;

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

     (4) to make any change in Article 10 or 12 that would limit or terminate the benefits
available to any holder of Senior Indebtedness of the Company or any Subsidiary Guarantor
(or Representatives therefor) under Article 10 or 12;

     (5) to add guarantees with respect to the Securities (including any Subsidiary
Guarantee) or to secure the Securities;

     (6) to add to the covenants of the Company for the benefit of the Holders or to
surrender any right or power herein conferred upon the Company or the Subsidiary Guarantors;

     (7) to comply with any requirements of the SEC in connection with qualifying this
Indenture under the TIA; or

     (8) to make any change that does not adversely affect the rights of any Securityholder.

 

55

          An amendment under this Section may not make any change that adversely affects the rights
under Article 10 or 12 of any holder of Senior Indebtedness of the Company or of a Subsidiary
Guarantor then outstanding unless the holders of such Senior Indebtedness (or any group or
representative thereof authorized to give a consent) consent to such change.

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

          Section 9.02. With Consent of Holders. The Company, the Subsidiary Guarantors and the
Trustee may amend this Indenture or the Securities without notice to any Securityholder but with
the written consent of the Holders of at least a majority in principal amount of the Securities.
Without the consent of each Securityholder affected, however, an amendment may not:

     (1) reduce the amount of Securities whose Holders must consent to an amendment;

     (2) reduce the rate of or extend the time for payment of interest on any Security;

     (3) reduce the principal of or extend the Stated Maturity of any Security;

     (4) reduce the premium payable upon a required purchase (to the extent the Company has
at the time become obligated by the terms of the Indenture to effect a required purchase) or
the redemption of any Security or change the time at which any Security may be redeemed in
accordance with Article 3 and paragraph 5 of the Securities;

     (5) make any Security payable in money other than that stated in the Security;

     (6) make any change in Article 10 or 12 or that adversely affects the rights of any
Securityholder under Article 10 or 12;

     (7) make any change in Section 6.04 or 6.07 or the second sentence of this Section; or

     (8) make any change in any Subsidiary Guarantee that would adversely affect the
Securityholders.

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

          An amendment under this Section may not make any change that adversely affects the rights
under Article 10 or 12 of any holder of Senior Indebtedness then outstanding unless the holders of
such Senior Indebtedness (or any group or representative thereof authorized to give a consent)
consent to such change.

 

56

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

          Section 9.03. Compliance with Trust Indenture Act. Every amendment to this Indenture
or the Securities shall comply with the TIA as then in effect.

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

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

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

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

          Section 9.07. Payment for Consent. Neither the Company nor any Affiliate of the
Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee 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 Securities unless such
consideration is offered to be paid or agreed to be paid to all Holders that so consent, waive or

 

57

agree to amend in the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

ARTICLE 10

Subordination of the Securities

          Section 10.01. Agreement To Subordinate. The Company agrees, and each Securityholder
by accepting a Security agrees, that the Indebtedness evidenced by the Securities are senior
unsecured, general obligations of the Company, subordinated in right of payment, to the extent and
in the manner provided in this Article 10, to the prior payment of all Senior Indebtedness of the
Company, whether outstanding on the Issue Date or thereafter incurred, including the Company’s
obligations under the Credit Agreement, and that the subordination is for the benefit of and
enforceable by the holders of such Senior Indebtedness. The Securities shall in all respects rank
pari passu with all other Senior Subordinated Indebtedness of the Company, and only
Indebtedness of the Company which is Senior Indebtedness shall rank senior to the Securities in
accordance with the provisions set forth herein. All provisions of this Article 10 shall be
subject to Section 10.12.

          Section 10.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution
of the assets of the Company upon a total or partial liquidation or a total or partial dissolution
of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property:

     (1) subject to the provisions of Section 10.12, holders of Senior Indebtedness of the
Company shall be entitled to receive payment in full of such Senior Indebtedness before
Securityholders shall be entitled to receive any payment of principal of or interest on the
Securities; and

     (2) until the Senior Indebtedness of the Company is paid in full, any payment or
distribution to which Securityholders would be entitled but for this Article 10 shall be
made to holders of such Senior Indebtedness as their interests may appear, except that
Securityholders may receive shares of stock and any debt securities that are subordinated to
such Senior Indebtedness to at least the same extent as the Securities.

          Section 10.03. Default on Designated Senior Indebtedness. The Company may not pay the
principal of, premium (if any) or interest on the Securities or make any deposit pursuant to
Section 8.01 and may not repurchase, redeem or otherwise retire any Securities (collectively,
“pay the Securities”) if (i) any Designated Senior Indebtedness of the Company is not paid
when due or (ii) any other default on Designated Senior Indebtedness of the Company occurs and the
maturity of such Designated Senior Indebtedness is accelerated in accordance with its terms unless,
in either case, (x) the default has been cured or waived and any such acceleration has been
rescinded or (y) such Designated Senior Indebtedness has been paid in full; provided,
however, that the Company may pay the Securities without regard to the foregoing if the
Company and the Trustee receive written notice approving such payment from the Representative of
the Designated Senior Indebtedness with respect to which either of the events set forth in clause
(i) or (ii) of this sentence has occurred and is continuing. During the

 

58

continuance of any default (other than a default described in clause (i) or (ii) of the
preceding sentence) with respect to any Designated Senior Indebtedness of the Company pursuant to
which the maturity thereof may be accelerated immediately without further notice (except such
notice as may be required to effect such acceleration) or the expiration of any applicable grace
periods, the Company may not pay the Securities for a period (a “Payment Blockage Period”)
commencing upon the receipt by the Trustee (with a copy to the Company) of written notice (a
“Blockage Notice”) of such default from the Representative of the holders of such
Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period and
ending 179 days thereafter (or earlier if such Payment Blockage Period is terminated (i) by written
notice to the Trustee and the Company from the Person or Persons who gave such Blockage Notice,
(ii) because the default giving rise to such Blockage Notice is no longer continuing or (iii)
because such Designated Senior Indebtedness has been repaid in full). Notwithstanding the
provisions described in the immediately preceding sentence, unless the holders of such Designated
Senior Indebtedness giving such Blockage Notice or the Representative of such holders shall have
accelerated the maturity of such Designated Senior Indebtedness, the Company shall resume payments
on the Securities after the end of such Payment Blockage Period. The Securities shall not be
subject to more than one Payment Blockage Period in any consecutive 360-day period, irrespective of
the number of defaults with respect to Designated Senior Indebtedness of the Company during such
period. For purposes of this Section, no default or event of default which existed or was
continuing on the date of the commencement of any Payment Blockage Period with respect to the
Designated Senior Indebtedness initiating such Payment Blockage Period shall be, or be made, the
basis of the commencement of a subsequent Payment Blockage Period by the Representative of such
Designated Senior Indebtedness, whether or not within a period of 360 consecutive days, unless such
default or event of default shall have been cured or waived for a period of not less than 90
consecutive days.

          Section 10.04. Acceleration of Payment of Securities. If payment of the Securities is
accelerated because of an Event of Default, the Company or the Trustee (upon receipt of the
requisite information from the Company) shall promptly notify the holders of Designated Senior
Indebtedness (or their Representatives) of the Company of the acceleration.

          Section 10.05. When Distribution Must Be Paid Over. If a distribution is made to
Securityholders that because of this Article 10 should not have been made to them, the
Securityholders who receive the distribution shall hold it in trust for holders of Senior
Indebtedness of the Company and pay it over to them as their interests may appear.

          Section 10.06. Subrogation. After all Senior Indebtedness of the Company is paid in
full and until the Securities are paid in full, Securityholders shall be subrogated to the rights
of holders of such Senior Indebtedness to receive distributions applicable to such Senior
Indebtedness. A distribution made under this Article 10 to holders of Senior Indebtedness of the
Company which otherwise would have been made to Securityholders is not, as between the Company and
Securityholders, a payment by the Company on such Senior Indebtedness.

          Section 10.07. Relative Rights. This Article 10 defines the relative rights of
Securityholders and holders of Senior Indebtedness of the Company. Nothing in this Indenture
shall:

 

59

     (1) impair, as between the Company and Securityholders, the obligation of the Company,
which is absolute and unconditional, to pay principal of and interest on the Securities in
accordance with their terms; or

     (2) prevent the Trustee or any Securityholder from exercising its available remedies
upon a Default, subject to the rights of holders of Senior Indebtedness of the Company to
receive distributions otherwise payable to Securityholders.

          Section 10.08. Subordination May Not Be Impaired by Company. No right of any holder
of Senior Indebtedness of the Company to enforce the subordination of the Indebtedness evidenced by
the Securities shall be impaired by any act or failure to act by the Company or by its failure to
comply with this Indenture.

          Section 10.09. Rights of Trustee and Paying Agent. Notwithstanding Section 10.03, the
Trustee or Paying Agent may continue to make payments on the Securities and shall not be charged
with knowledge of the existence of facts that would prohibit the making of any such payments
unless, not less than two Business Days prior to the date of such payment, a Trust Officer of the
Trustee receives notice satisfactory to it that payments may not be made under this Article 10.
The Company, the Registrar or co-registrar, the Paying Agent, a Representative or a holder of
Senior Indebtedness may give the notice; provided, however, that, if an issue of
Senior Indebtedness of the Company has a Representative, only the Representative may give the
notice.

          The Trustee in its individual or any other capacity may hold Senior Indebtedness of the
Company with the same rights it would have if it were not Trustee. The Registrar and co-registrar
and the Paying Agent may do the same with like rights. The Trustee shall be entitled to all the
rights set forth in this Article 10 with respect to any such Senior Indebtedness which may at any
time be held by it, to the same extent as any other holder of such Senior Indebtedness; and nothing
in Article 7 shall deprive the Trustee of any of its rights as such holder. Nothing in this
Article 10 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 7.07.

          Section 10.10. Distribution or Notice to Representative. Whenever a distribution is
to be made or a notice given to holders of Senior Indebtedness of the Company, the distribution may
be made and the notice given to their Representative (if any).

          Section 10.11. Article 10 Not To Prevent Events of Default or Limit Right To
Accelerate. The failure to make a payment pursuant to the Securities by reason of any
provision in this Article 10 shall not be construed as preventing the occurrence of a Default.
Nothing in this Article 10 shall have any effect on the right of the Securityholders or the Trustee
to accelerate the maturity of the Securities.

          Section 10.12. Trust Moneys Not Subordinated. Notwithstanding anything contained
herein to the contrary, payment from the money or the proceeds of U.S. Government Obligations
deposited in trust with the Trustee in accordance with the provisions of Article 8 for the payment
of principal of and interest on the Securities shall not be subordinated to the prior payment of
any Senior Indebtedness of the Company or subject to the restrictions set forth in this Article 10,
and none of the Securityholders shall be obligated to pay over any such amount to the

 

60

Company or any holder of such Senior Indebtedness of the Company or any other creditor of the
Company.

          Section 10.13. Trustee Entitled To Rely. Upon any payment or distribution pursuant to
this Article 10, the Trustee and the Securityholders shall be entitled to rely (i) upon any order
or decree of a court of competent jurisdiction in which any proceedings of the nature referred to
in Section 10.02 are pending, (ii) upon a certificate of the liquidating trustee or agent or other
Person making such payment or distribution to the Trustee or to the Securityholders or (iii) upon
the Representatives for the holders of Senior Indebtedness of the Company for the purpose of
ascertaining the Persons entitled to participate in such payment or distribution, the holders of
such Senior Indebtedness and other Indebtedness of the Company, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article 10. In the event that the Trustee determines, in good faith, that evidence is
required with respect to the right of any Person as a holder of Senior Indebtedness of the Company
to participate in any payment or distribution pursuant to this Article 10, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and other facts pertinent to the rights of such Person under this
Article 10, and, if such evidence is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive such payment. The
provisions of Sections 7.01 and 7.02 shall be applicable to all actions or omissions of actions by
the Trustee pursuant to this Article 10.

          Section 10.14. Trustee To Effectuate Subordination. Each Securityholder by accepting
a Security authorizes and directs the Trustee on his behalf to take such action as may be necessary
or appropriate to acknowledge or effectuate the subordination between the Securityholders and the
holders of Senior Indebtedness of the Company as provided in this Article 10 and appoints the
Trustee as attorney-in-fact for any and all such purposes.

          Section 10.15. Trustee Not Fiduciary for Holders of Senior Indebtedness of the
Company. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness of the Company. The Trustee undertakes to perform or to observe only such of the
covenants and obligations as are specifically set forth in this Article 10, and no implied
covenants or obligations with respect to such holders of such Senior Indebtedness shall be implied
in this Indenture against the Trustee.

          Section 10.16. Reliance by Holders of Senior Indebtedness of the Company on Subordination
Provisions. Each Securityholder by accepting a Security acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement and a consideration
to each holder of any Senior Indebtedness of the Company, whether such Senior Indebtedness was
created or acquired before or after the issuance of the Securities, to acquire and continue to
hold, or to continue to hold, such Senior Indebtedness and such holder of such Senior Indebtedness
shall be deemed conclusively to have relied on such subordination provisions in acquiring and
continuing to hold, or in continuing to hold, such Senior Indebtedness.

 

61

ARTICLE 11

Subsidiary Guarantees

          Section 11.01. Subsidiary Guarantees. Each Subsidiary Guarantor, jointly and
severally, as primary obligor and not merely as surety, hereby irrevocably, fully and
unconditionally Guarantees on a senior subordinated basis to each Holder and to the Trustee and its
successors and assigns (a) the full and punctual payment of principal of and interest on the
Securities when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, and
all other monetary obligations of the Company under this Indenture and the Securities and (b) the
full and punctual performance within applicable grace periods of all other obligations of the
Company under this Indenture and the Securities (all the foregoing obligations hereinafter
collectively called the “Guaranteed Obligations”). Each Subsidiary Guarantor further
agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without
notice or further assent from such Subsidiary Guarantor, and that such Subsidiary Guarantor shall
remain bound under this Article 11 notwithstanding any extension or renewal of any such Guaranteed
Obligation.

          Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the
Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment.
Each Subsidiary Guarantor waives notice of any default under the Securities or the Guaranteed
Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (a)
the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or
remedy against the Company or any other Person under this Indenture, the Securities or any other
agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver,
amendment or modification of any of the terms or provisions of this Indenture, the Securities or
any other agreement; (d) the release of any security held by any Holder or the Trustee for the
Guaranteed Obligations or any of them; (e) the failure of any Holder or Trustee to exercise any
right or remedy against any other guarantor of the Guaranteed Obligations; or (f) except as
provided in Section 11.06, any change in the ownership of such Subsidiary Guarantor.

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

          Each Subsidiary Guarantee is, to the extent and manner set forth in Article 12, subordinated
and subject in right of payment to the prior payment in full in cash or cash equivalents of all
Senior Indebtedness of the Subsidiary Guarantor giving such Subsidiary Guarantee and each
Subsidiary Guarantee is hereby made subject to such provisions of this Indenture.

          Except as expressly set forth in Sections 8.01(b), 11.02 and 11.06, the obligations of each
Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or
termination for any reason, including any claim of waiver, release, surrender, alteration or
compromise, and shall not be subject to any defense of setoff, counterclaim,

 

62

recoupment or termination whatsoever or by reason of the invalidity, illegality or
unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of
the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or
impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or
demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any
waiver or modification of any thereof, by any default, failure or delay, wilful or otherwise, in
the performance of the Guaranteed Obligations, or by any other act or thing or omission or delay to
do any other act or thing which may or might in any manner or to any extent vary the risk of such
Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a
matter of law or equity.

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

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

          Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in
respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed
Obligations and all obligations to which the Guaranteed Obligations are subordinated as provided in
Article 12. Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the
Holders and the Trustee, on the other hand, (x) the maturity of the Guaranteed Obligations
Guaranteed hereby may be accelerated as provided in Article 6 for the purposes of such Subsidiary
Guarantor’s Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the Guaranteed Obligations Guaranteed hereby, and (y) in
the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article
6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and
payable by such Subsidiary Guarantor for the purposes of this Section.

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

          Section 11.02. Limitation on Liability. Any term or provision of this Indenture to
the contrary notwithstanding, the maximum, aggregate amount of the obligations guaranteed

 

63

hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby
guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally.

          Section 11.03. Successors and Assigns. This Article 11 shall be binding upon each
Subsidiary Guarantor and its successors and assigns and shall ensure to the benefit of the
successors and assigns of the Trustee and the Holders and, in the event of any transfer or
assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that
party in this Indenture and in the Securities shall automatically extend to and be vested in such
transferee or assignee, all subject to the terms and conditions of this Indenture.

          Section 11.04. No Waiver. Neither a failure nor a delay on the part of either the
Trustee or the Holders in exercising any right, power or privilege under this Article 11 shall
operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or
further exercise of any right, power or privilege. The rights, remedies and benefits of the
Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article 11 at law, in equity, by
statute or otherwise.

          Section 11.05. Modification. No modification, amendment or waiver of any provision of
this Article 11, nor the consent to any departure by any Subsidiary Guarantor therefrom, shall in
any event be effective unless the same shall be in writing and signed by the Trustee, and then such
waiver or consent shall be effective only in the specific instance and for the purpose for which
given. No notice to or demand on any Subsidiary Guarantor in any case shall entitle such
Subsidiary Guarantor to any other or further notice or demand in the same, similar or other
circumstances.

          Section 11.06. Release of Subsidiary Guarantor. This Subsidiary Guarantee as to any
Subsidiary Guarantor shall terminate and be of no further force or effect (i) upon the sale
(including any sale pursuant to any exercise of remedies by a holder of Senior Indebtedness of such
Subsidiary Guarantor) or other disposition (including by way of consolidation or merger) of such
Subsidiary Guarantor or (ii) upon the sale or disposition of all or substantially all of the assets
of such Subsidiary Guarantor, in each case other than to the Company or an Affiliate of the
Company; provided, however, that such sale or transfer shall be deemed to
constitute an Asset Disposition and the Company shall comply with all applicable provisions of
Section 4.06 with respect to such Asset Disposition.

ARTICLE 12

Subordination of Subsidiary Guarantees

          Section 12.01. Agreement To Subordinate. Each Subsidiary Guarantor agrees, and each
Securityholder by accepting a Security agrees, that the Obligations of such Subsidiary Guarantor
under its Subsidiary Guarantee are subordinated in right of payment, to the extent and in the
manner provided in this Article 12, to the prior payment in full in cash or cash equivalents of all
Senior Indebtedness of such Subsidiary Guarantor and that the subordination is for the

 

64

benefit of and enforceable by the holders of such Senior Indebtedness. The Obligations of
each Subsidiary Guarantor under its Subsidiary Guarantee shall in all respects rank pari
passu with all other Senior Subordinated Indebtedness of such Subsidiary Guarantor and only
Senior Indebtedness of such Subsidiary Guarantor (including such Subsidiary Guarantor’s Guarantees
of Senior Indebtedness of the Company) shall rank senior to the Subsidiary Guarantee of such
Subsidiary Guarantor in accordance with the provisions set forth herein.

          Section 12.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution
of the assets of any Subsidiary Guarantor to creditors upon a total or partial liquidation or a
total or partial dissolution of such Subsidiary Guarantor or in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding relating to such Subsidiary Guarantor or its
property:

     (1) holders of Senior Indebtedness of such Subsidiary Guarantor shall be entitled to
receive payment in full of such Senior Indebtedness in cash or cash equivalents before
Securityholders shall be entitled to receive any payment pursuant to the Subsidiary
Guarantee of such Subsidiary Guarantor; and

     (2) until the Senior Indebtedness of such Subsidiary Guarantor is paid in full in cash
or cash equivalents, any distribution to which Securityholders would be entitled but for
this Article 12 shall be made to holders of such Senior Indebtedness as their interests may
appear, except that Securityholders may receive shares of stock and any debt securities of
such Subsidiary Guarantor that are subordinated to Senior Indebtedness, and to any debt
securities received by holders of Senior Indebtedness, of such Subsidiary Guarantor to at
least the same extent as the Subsidiary Guarantee of such Subsidiary Guarantor are
subordinated to Senior Indebtedness of such Subsidiary Guarantor.

          Section 12.03. Default on Designated Senior Indebtedness of Subsidiary Guarantor. No
Subsidiary Guarantor may make any payment pursuant to its Subsidiary Guarantee or repurchase,
redeem or otherwise retire or defease any Securities or other Obligations (collectively, “pay
its Subsidiary Guarantee”) if (i) any Designated Senior Indebtedness of such Subsidiary
Guarantor is not paid when due or (ii) any other default on Designated Senior Indebtedness of such
Subsidiary Guarantor occurs and the maturity of such Designated Senior Indebtedness is accelerated
in accordance with its terms unless, in either case, (x) the default has been cured or waived and
any such acceleration has been rescinded or (y) such Designated Senior Indebtedness has been paid
in full; provided, however, that such Subsidiary Guarantor may pay its Subsidiary
Guarantee without regard to the foregoing if such Subsidiary Guarantor and the Trustee receive
written notice approving such payment from the Representative of the Designated Senior Indebtedness
with respect to which either of the events set forth in clause (i) or (ii) of this sentence has
occurred and is continuing. During the continuance of any default (other than a default described
in clause (i) or (ii) of the preceding sentence) with respect to any Designated Senior Indebtedness
of such Subsidiary Guarantor pursuant to which the maturity thereof may be accelerated immediately
without further notice (except such notice as may be required to effect such acceleration) or the
expiration of any applicable grace periods, such Subsidiary Guarantor may not pay its Guarantee for
a period (a “Subsidiary Guarantor Payment Blockage Period”) commencing upon the receipt by
the Trustee (with a copy to such Subsidiary Guarantor) of written notice (a “Subsidiary
Guarantor Blockage 

 

65

Notice”) of such default from the Representative of the holders of such Designated
Senior Indebtedness specifying an election to effect a Subsidiary Guarantor Payment Blockage Period
and ending 179 days thereafter (or earlier if such Subsidiary Guarantor Payment Blockage Period is
terminated (i) by written notice to the Trustee and such Subsidiary Guarantor from the Person or
Persons who gave such Subsidiary Guarantor Blockage Notice, (ii) because the default giving rise to
such Subsidiary Guarantor Blockage Notice is no longer continuing or (iii) because such Designated
Senior Indebtedness has been repaid in full). Notwithstanding the provisions described in the
immediately preceding sentence (but subject to the provisions contained in the first sentence of
this Section), unless the holders of Designated Senior Indebtedness giving such Subsidiary
Guarantor Blockage Notice or the Representative of such holders shall have accelerated the maturity
of such Designated Senior Indebtedness, such Subsidiary Guarantor shall resume payments pursuant to
its Subsidiary Guarantee after the end of such Subsidiary Guarantor Payment Blockage Period. A
Subsidiary Guarantee shall not be subject to more than one Subsidiary Guarantor Payment Blockage
Period in any consecutive 360-day period, irrespective of the number of defaults with respect to
Designated Senior Indebtedness of such Subsidiary Guarantor during such period. For purposes of
this Section, no default or event of default which existed or was continuing on the date of the
commencement of any Subsidiary Guarantor Payment Blockage Period with respect to the Designated
Senior Indebtedness initiating such Subsidiary Guarantor Payment Blockage Period shall be, or be
made, the basis of the commencement of a subsequent Subsidiary Guarantor Payment Blockage Period by
the Representative of such Designated Senior Indebtedness, whether or not within a period of 360
consecutive days, unless such default or event of default shall have been cured or waived for a
period of not less than 90 consecutive days.

          Section 12.04. Demand for Payment. If a demand for payment is made on a Subsidiary
Guarantor pursuant to Article 11, the Trustee shall promptly notify the holders of the Designated
Senior Indebtedness (or their Representatives) of such Subsidiary Guarantor of such demand.

          Section 12.05. When Distribution Must Be Paid Over. If a distribution is made to
Securityholders that because of this Article 12 should not have been made to them, the
Securityholders who receive the distribution shall hold it in trust for holders of the relevant
Senior Indebtedness and pay it over to them or their Representative as their interests may appear.

          Section 12.06. Subrogation. After all Senior Indebtedness of a Subsidiary Guarantor
is paid in full and until the Securities are paid in full, Securityholders shall be subrogated to
the rights of holders of such Senior Indebtedness to receive distributions applicable to Senior
Indebtedness. A distribution made under this Article 12 to holders of such Senior Indebtedness
which otherwise would have been made to Securityholders is not, as between the relevant Subsidiary
Guarantor and Securityholders, a payment by such Subsidiary Guarantor on such Senior Indebtedness.

          Section 12.07. Relative Rights. This Article 12 defines the relative rights of
Securityholders and holders of Senior Indebtedness of a Subsidiary Guarantor. Nothing in this
Indenture shall:

 

 66

     (1) impair, as between such Subsidiary Guarantor and Securityholders, the obligation of
such Subsidiary Guarantor, which is absolute and unconditional, to pay the Obligations to
the extent set forth in Article 11; or

     (2) prevent the Trustee or any Securityholder from exercising its available remedies
upon a default by such Subsidiary Guarantor under its Subsidiary Guarantee, subject to the
rights of holders of Senior Indebtedness of such Subsidiary Guarantor to receive
distributions otherwise payable to Securityholders.

          Section 12.08. Subordination May Not Be Impaired by Subsidiary Guarantor. No right of
any holder of Senior Indebtedness of any Subsidiary Guarantor to enforce the subordination of the
Obligations of such Subsidiary Guarantor shall be impaired by any act or failure to act by such
Subsidiary Guarantor or by its failure to comply with this Indenture.

          Section 12.09. Rights of Trustee and Paying Agent. Notwithstanding Section 12.03, the
Trustee or Paying Agent may continue to make payments pursuant to any Subsidiary Guarantee and
shall not be charged with knowledge of the existence of facts that would prohibit the making of any
such payments unless, not less than two Business Days prior to the date of such payment, a Trust
Officer of the Trustee receives written notice satisfactory to it that payments may not be made
under this Article 12. The Company, such Subsidiary Guarantor, the Registrar or co-registrar, the
Paying Agent, a Representative or a holder of Senior Indebtedness of such Subsidiary Guarantor may
give the notice; provided, however, that, if an issue of Senior Indebtedness of
such Subsidiary Guarantor has a Representative, only the Representative may give the notice.

          The Trustee in its individual or any other capacity may hold Senior Indebtedness of any
Subsidiary Guarantor with the same rights it would have if it were not Trustee. The Registrar and
co-registrar and the Paying Agent may do the same with like rights. The Trustee shall be entitled
to all the rights set forth in this Article 12 with respect to any Senior Indebtedness of any
Subsidiary Guarantor which may at any time be held by it, to the same extent as any other holder of
such Senior Indebtedness of such Subsidiary Guarantor; and nothing in Article 7 shall deprive the
Trustee of any of its rights as such holder. Nothing in this Article 12 shall apply to claims of,
or payments to, the Trustee under or pursuant to Section 7.07.

          Section 12.10. Distribution or Notice to Representative. Whenever a distribution is
to be made or a notice given to holders of Senior Indebtedness of any Subsidiary Guarantor, the
distribution may be made and the notice given to their Representative (if any).

          Section 12.11. Article 12 Not To Prevent Defaults Under a Subsidiary Guarantee or Limit
Right To Demand Payment. The failure to make a payment pursuant to a Subsidiary Guarantee by
reason of any provision in this Article 12 shall not be construed as preventing the occurrence of a
default under such Subsidiary Guarantee. Nothing in this Article 12 shall have any effect on the
right of the Securityholders or the Trustee to make a demand for payment on any Subsidiary
Guarantor pursuant to its Subsidiary Guarantee.

          Section 12.12. Trustee Entitled To Rely. Upon any payment or distribution pursuant to
this Article 12, the Trustee and the Securityholders shall be entitled to rely (i) upon

 

67

any order or decree of a court of competent jurisdiction in which any proceedings of the
nature referred to in Section 12.02 are pending, (ii) upon a certificate of the liquidating trustee
or agent or other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representative for the holders of Senior Indebtedness of any
Subsidiary Guarantor for the purpose of ascertaining the Persons entitled to participate in such
payment or distribution, the holders of such Senior Indebtedness and other Indebtedness of such
Subsidiary Guarantor, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 12. In the event that
the Trustee determines, in good faith, that evidence is required with respect to the right of any
Person as a holder of Senior Indebtedness of such Subsidiary Guarantor to participate in any
payment or distribution pursuant to this Article 12, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness of
such Subsidiary Guarantor held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and other facts pertinent to the rights of such Person
under this Article 12, and, if such evidence is not furnished, the Trustee may defer any payment to
such Person pending judicial determination as to the right of such Person to receive such payment.
The provisions of Sections 7.01 and 7.02 shall be applicable to all actions or omissions of actions
by the Trustee pursuant to this Article 12.

          Section 12.13. Trustee To Effectuate Subordination. Each Securityholder by accepting
a Security authorizes and directs the Trustee on his behalf to take such action as may be necessary
or appropriate to acknowledge or effectuate the subordination between the Securityholders and the
holders of Senior Indebtedness of any Subsidiary Guarantor as provided in this Article 12 and
appoints the Trustee as attorney-in-fact for any and all such purposes.

          Section 12.14. Trustee Not Fiduciary for Holders of Senior Indebtedness of Subsidiary
Guarantor. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness of any Subsidiary Guarantor and shall not be liable to any such holders if it shall
mistakenly pay over or distribute to Securityholders or the Company or any other Person, money or
assets to which any holders of such Senior Indebtedness shall be entitled by virtue of this Article
12 or otherwise.

          Section 12.15. Reliance by Holders of Senior Indebtedness on Subordination Provisions.
Each Securityholder by accepting a Security acknowledges and agrees that the foregoing

holder of any Senior Indebtedness of any Subsidiary Guarantor, whether such Senior Indebtedness was
created or acquired before or after the issuance of the Securities, to acquire and continue to
hold, or to continue to hold, such Senior Indebtedness and such holder of Senior Indebtedness shall

Securities outstanding at the time shall be considered in any such determination.

day on which banking institutions are not required to be open in the State of New York or in the
State of Texas. If a payment date is a Legal Holiday, payment shall be made on the next succeeding

affected.

          Section 13.09. Governing Law. This Indenture and the Securities shall be governed by,

FORM OF REVERSE SIDE OF SECURITY

9.75% Senior Subordinated Notes Due 2016

1. Interest

          Denbury Resources Inc., a Delaware corporation (such corporation, and its successors and
assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises
to pay interest on the principal amount of this Security at the rate per annum shown above. The
Company will pay interest semiannually on March 1 and September 1 of each year, commencing
September 1, 2009. Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from February 13, 2009. Interest will be
computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay interest on
overdue principal at the rate borne by the Securities plus 1% per annum, and it shall pay interest
on overdue installments of interest at the same rate to the extent lawful.

2. Method of Payment

          The Company will pay interest on the Securities (except defaulted interest) to the Persons who
are registered holders of Securities at the close of business on the February 14 or August 17 next
preceding the interest payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the United States that
at the time of payment is legal tender for payment of public and private debts. Payments in
respect of the Securities represented by a Global Security (including principal, premium, if any,
and interest) will be made by wire transfer of immediately available funds to the accounts
specified by The Depository Trust Company. The Company will make all payments in respect of a
certificated Security (including principal, premium, if any, and interest) by mailing a check to
the registered address of each Holder thereof; provided, however, that payments on
a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the
payee with a bank in the United States if such Holder elects payment by wire transfer by giving
written notice to the Trustee or the Paying Agent to such effect designating such account no later
than 30 days immediately preceding the relevant due date for payment (or such other date as the
Trustee may accept in its discretion).

3. Paying Agent and Registrar

          Initially, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), will act as Paying
Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or
co-registrar without notice. The Company or any Wholly Owned Subsidiary may act as Paying Agent,
Registrar or co-registrar.

4. Indenture

          The Company issued the Securities under an Indenture dated as of February 13, 2009
(“Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. The terms

 

2

of the Securities include those stated in the Indenture and those made part of the Indenture
by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on
the date of the Indenture (the “Act”). Terms defined in the Indenture and not defined herein have
the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of those terms.

          The Securities are general unsecured obligations of the Company. The Company shall be
entitled, subject to its compliance with Section 4.03 of the Indenture, to issue Additional
Securities pursuant to Section 2.13 of the Indenture. The Securities issued on the Issue Date and
any Additional Securities will be treated as a single class for all purposes under the Indenture.
The Indenture contains covenants that limit the ability of the Company and its subsidiaries to
incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital
stock; make investments; engage in transactions with affiliates; transfer or sell assets; guarantee
indebtedness; restrict dividends or other payments of subsidiaries; and consolidate, merge or
transfer all or substantially all of its assets and the assets of its subsidiaries. These
covenants are subject to important exceptions and qualifications.

5. Optional Redemption

          Except as set forth below, the Company shall not be entitled to redeem the Securities prior to
March 1, 2013.

          On and after March 1, 2013, the Company shall be entitled at its option to redeem all or a
portion of the Securities upon not less than 30 nor more than 60 days’ notice, at the redemption
prices (expressed in percentages of principal amount on the redemption date), plus accrued and
unpaid interest to the redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date), if redeemed during the
12-month period commencing on March 1 of the years set forth below:

	 	 	 	 	 
	Period	 	Redemption Price
	2013
	 	 	104.8750	%
	2014
	 	 	102.4375	%
	2015 and thereafter
	 	 	100.0000	%

          Prior to March 1, 2012, the Company may at its option on one or more occasions redeem
Securities (which includes Additional Securities, if any) in an aggregate principal amount not to
exceed 35% of the aggregate principal amount of the Securities (which includes Additional
Securities, if any) originally issued at a redemption price (expressed as a percentage of principal
amount) of 109.75%, plus accrued and unpaid interest to the redemption date, with the net cash
proceeds from one or more Stock Offerings; provided, however, that

     (1) at least 65% of such aggregate principal amount of Securities (which includes
Additional Securities, if any) remains outstanding immediately after the occurrence of each
such redemption (other than Securities held, directly or indirectly, by the Company or its
Affiliates); and

 

3

     (2) each such redemption occurs within 60 days after the date of the related Stock
Offering.

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 Securities to be redeemed at its registered address. Securities
in denominations larger than $1,000 principal amount may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the redemption price of and accrued interest on
all Securities (or portions thereof) to be redeemed on the redemption date is deposited with the
Paying Agent on or before the redemption date and certain other conditions are satisfied, on and
after such date interest ceases to accrue on such Securities (or such portions thereof) called for
redemption.

7. Put Provisions

          Upon a Change of Control, any Holder of Securities will have the right to cause the Company to
repurchase all or any part of the Securities of such Holder at a purchase price equal to 101% of
the principal amount of the Securities to be repurchased on the date of purchase plus accrued and
unpaid interest, if any, to the date of repurchase (subject to the right of holders of record on
the relevant record date to receive interest due on the relevant interest payment date) as provided
in, and subject to the terms of, the Indenture.

8. Subordination

          The Securities are subordinated to Senior Indebtedness of the Company, as defined in the
Indenture. To the extent provided in the Indenture, Senior Indebtedness of the Company must be
paid in full in cash before the Securities may be paid. The Company agrees, and each
Securityholder by accepting a Security agrees, to the subordination provisions contained in the
Indenture and authorizes the Trustee to give it effect and appoints the Trustee as attorney-in-fact
for such purpose.

9. Guaranties

          The payment by the Company of the principal of, and premium and interest on, the Securities is
fully and unconditionally guaranteed on a joint and several senior subordinated basis by each of
the Subsidiary Guarantors on the terms set forth in the Indenture.

10. Denominations; Transfer; Exchange

          The Securities are in registered form without coupons in denominations of $2,000 principal
amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance
with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not register the transfer of or exchange any Securities selected
for redemption (except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or any Securities for a period of 15 days before a selection of
Securities to be redeemed or 15 days before an interest payment date.

 

4

11. Persons Deemed Owners

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

12. Unclaimed Money

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

13. Discharge and Defeasance

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

14. Amendment, Waiver

          Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities
may be amended with the written consent of the Holders of at least a majority in principal amount
of the Securities then outstanding and (ii) any default or noncompliance with any provisions may be
waived with the written consent of the Holders of at least a majority in principal amount of the
Securities then outstanding. Subject to certain exceptions set forth in the Indenture, without
notice to or the consent of any Securityholder, the Company, the Subsidiary Guarantors and the
Trustee may amend the Indenture or the Securities to cure any ambiguity, omission, defect or
inconsistency, or to comply with Article 5 of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities (provided that the uncertificated
Securities are issued in registered form for purposes of Section 163(f) of the Code, or in a manner
such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code), or to
make any change to the subordination provisions of the Indenture that would limit or terminate the
benefits available to any holder of Senior Indebtedness (or its Representative) of the Company or
any Subsidiary Guarantor, or to add guarantees (including Subsidiary Guarantees) with respect to
the Securities, or to secure the Securities, or to add to the covenants of the Company for the
benefit of the Holders, or to surrender any right or power conferred on the Company or any
Subsidiary Guarantor, or to make any change that does not adversely affect the rights of any
Securityholder, or to comply with any requirement of the SEC in connection with qualifying the
Indenture under the Act. No amendment may be made to the subordination provisions of the Indenture
that adversely affects the rights of any holder of Senior Indebtedness of the Company or of any

Representative) consent to such change.

15. Defaults and Remedies

          Under the Indenture, Events of Default include (i) default for 30 days in payment of interest
on the Securities when due; (ii) default in payment of principal on the Securities at maturity,
upon redemption pursuant to paragraph 5 of the Securities, upon declaration or acceleration or
otherwise, or failure by the Company to redeem or purchase Securities when required; (iii) failure
by the Company to comply with its obligations under certain covenants; (iv) failure by the Company
to comply with other agreements in the Indenture or the Securities, in certain cases subject to
notice and lapse of time; (v) certain accelerations (including failure to pay within any grace
period after final maturity) of other Indebtedness of the Company or any Significant Subsidiary
(other than Limited Recourse Indebtedness) if the amount accelerated (or so unpaid) exceeds $10.0
million; (vi) certain events of bankruptcy, insolvency or reorganization with respect to the
Company or a Significant Subsidiary; (vii) any judgment or decree for the payment of money in
excess of $10.0 million is rendered against the Company or a Significant Subsidiary, remains
outstanding for a period of 60 days following such judgment or decree and is not discharged, waived
or stayed within 10 days after notice; or (viii) any Subsidiary Guarantee ceases or otherwise fails
to be in full force and effect (other than in accordance with the terms of such Subsidiary
Guarantee) or any Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary
Guarantee if such default continues for a period of 10 days after notice thereof to the Company.
If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the outstanding Securities may declare the principal of and accrued but unpaid
interest on all the Securities to be due and payable immediately. Certain events of bankruptcy,
insolvency or reorganization are Events of Default which will result in the Securities being due
and payable immediately upon the occurrence of such Events of Default. A default under clauses
(iv), (v), (vii) or (viii) will not constitute an Event of Default until the Trustee or the Holders
of 25% in principal amount of the outstanding Securities notifies the Company of the default and
the Company does not cure such default within the time specified after receipt of such notice.

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

16. Trustee Dealings with the Company

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

17. No Recourse Against Others

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

authenticating agent) manually signs the certificate of authentication on the other side of this
