4. EFFECT OF FIRST SUPPLEMENTAL INDENTURE; OPERATION OF AMENDMENTS.

(a) Effect of First Supplemental Indenture. In accordance with Article Nine of the Original
Indenture, upon the execution of this First Supplemental Indenture, the Original Indenture shall be
modified in accordance herewith, and this First Supplemental Indenture shall form a part of the
Original Indenture for all purposes; and every Holder of the Notes heretofore authenticated and

Supplemental Indenture, the Original Indenture and the Notes, and the rights of the Holders of the
Notes thereunder, shall remain unchanged and in full force and effect.

(b) Operation of Amendments. The provisions of this First Supplemental Indenture shall not
become operative until the date and time (such date and time, the “Operational Time”) the Company
notifies (in writing) i-Deal LLC, as depositary for the Notes under the Tender Offer (the
“Depositary”), that the Company has purchased Notes tendered and not withdrawn pursuant to the
Tender Offer. In the event the Company notifies (in writing) the Depositary that it has withdrawn

5. MATTERS CONCERNING THE TRUSTEE. The Trustee accepts the trusts of the Original Indenture,
as amended and supplemented by this First Supplemental Indenture, and agrees to perform the same,

supplemented by this First Supplemental Indenture, to which the parties hereto and the Holders from
time to time of the Notes agree and, except as expressly set forth in the Original Indenture, as
amended and supplemented by this First Supplemental Indenture, shall incur no liability or
responsibility in respect thereof. Without limiting the generality of the foregoing, the recitals
contained herein shall be taken as the statements of the Company and the Guarantors, and the
Trustee assumes no responsibility for their correctness, and the Trustee makes no representation as
to the validity or sufficiency of the Tender Offer, any consent solicitation statement or other
document used in connection with the Tender Offer, this First Supplemental Indenture or any
consents thereto. This First Supplemental Indenture is executed and accepted by the Trustee subject
to all the terms and conditions set forth in the Original Indenture with the same force and effect
as if those terms and conditions were repeated at length herein and made applicable to the Trustee
with respect hereto. In entering into this First Supplemental Indenture, the Trustee shall be
entitled to the benefit of every provision of the Original Indenture relating to the conduct or
affecting the liability or affording protection to the Trustee, whether or not elsewhere herein so
provided.

 

 

 

6. RATIFICATION AND CONFIRMATION OF THE ORIGINAL INDENTURE. Except as expressly amended

under the laws of the State of New York and for all purposes shall be governed by and construed in
accordance with the laws of the State of New York.

this First Supplemental Indenture limits, qualifies or conflicts with the duties imposed by
Sections 310-317 of the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), by
operation of Section 318(c) of the Trust Indenture Act, the imposed duties shall control.

First Supplemental Indenture have been inserted for convenience of reference only, are not to be
considered a part hereof and shall in no way modify or restrict any of the terms or provisions
hereof.

counterparts, each of which so executed shall be deemed to be an original, but such counterparts
shall constitute but one and the same agreement.

(f) Severability. In case any provision of this First Supplemental Indenture shall be
determined to be invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions hereof or of the Original Indenture shall not in any way be affected or
impaired thereby.

its authentication. The Notes shall be issued in registered, global form without interest coupons
and only shall be in minimum denominations of $1,000 and integral multiples of $1,000 in excess
thereof.

The terms and provisions contained in the Notes shall constitute, and are hereby expressly
made, a part of this Indenture and the Company, any Guarantors and the Trustee, by their execution
and delivery of this Indenture, expressly agree to such terms and provisions and to be bound
thereby. However, to the extent any provision of any Note conflicts with the express provisions of
this Indenture, the provisions of this Indenture shall govern and be controlling.

(b) Global Notes. Notes issued in global form shall be substantially in the form of
Exhibit A attached hereto (including the Global Note Legend thereon and the “Schedule of
Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form shall
be substantially in the form of Exhibit A attached hereto (but without the Global Note
Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached
thereto). Each Global Note shall represent such of the outstanding Notes as shall be specified
therein and each shall provide that it shall represent the aggregate principal amount of
outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of
outstanding Notes represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the
amount of any increase or decrease in the aggregate principal amount of outstanding Notes
represented thereby shall be made by the Trustee in accordance with instructions given by the
Holder thereof as required by Section 2.07 hereof.

(c) Temporary Global Notes. To the extent required by Regulation S, Notes offered and

Temporary Global Note, which shall be deposited on behalf of the purchasers of the Notes
represented thereby with the Trustee, as custodian for The Depository Trust Company (“ DTC”), and
registered in the name of the Depositary or the nominee of the Depositary for the accounts of
designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Company and

upon the receipt by the Trustee of an Officers’ Certificate from the Company certifying that the
Restricted Period may be terminated in accordance with Regulation S and that
beneficial interests in the Regulation S Temporary Global Note are permitted to be exchanged
for beneficial interests in Regulation S Permanent Global Notes. Following the termination of the
Restricted Period, beneficial interests in the Regulation S Temporary Global Note shall be
exchanged for beneficial interests in Regulation S Permanent Global Notes pursuant to the
Applicable Procedures. Simultaneously with the authentication of Regulation S Permanent Global
Notes, the Trustee shall cancel the Regulation S Temporary Global Note. The aggregate principal
amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes may
from time to time be increased or decreased by adjustments made on the records of the Trustee and

hereinafter provided.

Rights Agreement entered into with respect to such Additional Notes, (iv) any Additional Interest,

Notes immediately prior to the making or the consummation of the Exchange Offer regardless of any
other provisions regarding record dates herein and (v) all provisions of this Indenture shall be
construed and interpreted to permit the issuance of such Additional Notes and to allow such
Additional Notes to become fungible and interchangeable with the Initial Notes originally issued
under this Indenture (and Exchange Notes issued in exchange therefor). Indebtedness represented by
Additional Notes shall be subject to the covenants contained in this Indenture.

Section 2.02. Execution and Authentication.

(a) Two Officers of the Company shall sign the Notes for the Company by manual or facsimile
signature.

(b) The Trustee shall, upon a written order of the Company signed by two Officers of the
Company (an “ Authentication Order”) delivered to the Trustee from time to time, authenticate and

amount in accordance with an Exchange Offer pursuant to an applicable Registration Rights
Agreement.

(d) If an Officer whose signature is on a Note no longer holds that office at the time a Note
is authenticated, the Note shall nevertheless be valid.

(g) The Trustee may appoint an authenticating agent acceptable to the Company to authenticate
Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each

Company.

shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a
replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company,
an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee

does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

the Trustee receives proof satisfactory to it that the replaced Note is held by a protected
purchaser.

Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer

Notes that the Trustee knows are so owned shall be so disregarded.

 

51

 

Section 2.11. Temporary Notes.

(a) Until certificates representing Notes are ready for delivery, the Company may prepare and
the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary
Notes shall be substantially in the form of Definitive Notes but may have variations that the
Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the
Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate

interest, to the Persons who are Holders on the record date for the interest payment or a
subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01

cause to be mailed to Holders a notice that states the special record date, the related payment
date and the amount of such interest to be paid.

amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be
redeemed.

(b) If the Company complies with the provisions of the preceding paragraph, on and after the
redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for
redemption. If a Note is redeemed on or after an interest record date but on or prior to the
related interest payment date, then any accrued and unpaid interest shall be paid to the Holder in
whose name such Note was registered at the close of business on such record date. If any Note
called for redemption shall not be so paid upon surrender for redemption because of the failure of
the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal,

paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01

Section 4.07. Incurrence of Indebtedness and Issuance of Disqualified Stock.

(a) The Company shall not, and shall not cause or permit any of its Restricted Subsidiaries
to, create, issue, incur, assume, guarantee or otherwise in any manner become directly or
indirectly liable for the payment of or otherwise incur, contingently or otherwise (collectively, “
incur”), any Indebtedness (including any Acquired Debt and the issuance of
Disqualified Stock or the issuance of Preferred Stock by a Restricted Subsidiary), unless such
Indebtedness is incurred by the Company or any Guarantor and, in each case, the Company’s
Consolidated Fixed Charge Coverage Ratio for the most recent four full fiscal quarters for which
financial statements are available immediately preceding the incurrence of such Indebtedness taken
as one period is equal to or greater than 2.25:1.

(b) Notwithstanding the foregoing, the Company and, to the extent specifically set forth
below, the Restricted Subsidiaries may incur each and all of the following (collectively, the “
Permitted Debt”):

(i) Indebtedness of the Company or any Guarantors (whether as borrowers or guarantors)
under one or more Credit Facilities in an aggregate principal amount at any one time
outstanding not to exceed the greater of (A) $200.0 million, which amount shall be
permanently reduced by the amount of Net Available Cash from Asset Sales applied by the
Company or any Restricted Subsidiary thereof to permanently repay any such Indebtedness, and
not subsequently reinvested in Additional Assets, to the extent permitted pursuant to
Section 4.11 hereof, and (B) the sum of $100.0 million and 30% of Adjusted Consolidated Net
Tangible Assets, determined as of the date of the incurrence of such Indebtedness;

(ii) Indebtedness of the Company or any Guarantor pursuant to the Notes (excluding any
Additional Notes) and any Guarantee of the Notes;

(iii) Indebtedness of the Company or any Guarantor outstanding on the date of this
Indenture, and not otherwise referred to in this definition of Permitted Debt;

(iv) intercompany Indebtedness between or among the Company and any of its Restricted
Subsidiaries; provided, however, that:

(A) if the Company or any Guarantor is the obligor on such Indebtedness and
such Indebtedness is owed to a Restricted Subsidiary other than a Guarantor, such
Indebtedness must be expressly subordinated to the prior payment in full in cash of
all Obligations with respect to the Notes, in the case of the Company, or the
Guarantee, in the case of a Guarantor, pursuant to an intercompany note in the form
of Exhibit G hereto or pursuant to another agreement containing
substantially the same subordination provisions as those contained in Section 2.01
of Exhibit G hereto; and

(B) any subsequent issuance or transfer of Capital Stock that results in any
such Indebtedness being held by a Person other than the Company or a Restricted
Subsidiary thereof (other than pursuant to a pledge or a similar action under a
Credit Facility) and any sale or other transfer of any such Indebtedness to a Person
that is not either the Company or a Restricted Subsidiary thereof, shall be deemed,
in each case, to constitute an incurrence of such Indebtedness by the Company or
such Restricted Subsidiary, as the case may be, that was not permitted by this
clause (iv);

 

60

 

(v) guarantees by the Company or any Guarantor of any Indebtedness of the Company or

risks, basis risks, or other risks encountered in the Oil and Gas Business;

(vii) Indebtedness of the Company or any Restricted Subsidiary represented by Capital
Lease Obligations (whether or not incurred pursuant to sale and leaseback transactions) or
Purchase Money Obligations or other Indebtedness incurred or assumed in connection with the
acquisition or development of real or personal, movable or immovable, property in each case
incurred for the purpose of financing or refinancing all or any part of the purchase price
or cost of construction or improvement of property used in the business of the Company or
any Restricted Subsidiary, in an aggregate principal amount pursuant to this clause (vii)
not to exceed the greater of (A) $25.0 million and (B) 2.5% of Adjusted Consolidated Net
Tangible Assets outstanding at any time, determined as of the date of the incurrence of such
Indebtedness;

(viii) Indebtedness of the Company or any Restricted Subsidiary in connection with (A)
one or more standby letters of credit issued by the Company or a Restricted Subsidiary in
the ordinary course of business and (B) other letters of credit, surety, bid, performance,
appeal or similar bonds, bankers’ acceptances, completion guarantees or similar instruments;
provided that, in each case contemplated by this clause (viii), upon the drawing of such
letters of credit or other instrument, such obligations are reimbursed within 30 days
following such drawing; provided, further, that with respect to clauses (A) and (B), such
Indebtedness is not in connection with the borrowing of money or the obtaining of advances
or credit;

(ix) Indebtedness of the Company or any Restricted Subsidiary that constitutes

Eight or Article Eleven;

(xi) Indebtedness of the Company or any Restricted Subsidiary arising from agreements
for indemnification or purchase price adjustment obligations or similar obligations,
earn-outs or other similar obligations or from guarantees or letters of credit, surety bonds
or performance bonds securing any obligation of the Company or a Restricted Subsidiary
pursuant to such an agreement, in each case incurred or assumed in
connection with the acquisition or disposition of any business or assets of the Company
or a Restricted Subsidiary or Capital Stock of a Restricted Subsidiary;

 

61

 

(xii) Permitted Refinancing Indebtedness of the Company or any Guarantor issued in
exchange for, or the net proceeds of which are used to renew, extend, substitute, refund,
refinance or replace, any Indebtedness, including any Disqualified Stock, incurred pursuant
to paragraph (a) of this Section 4.07 and clauses (ii), (iii) and this clause (xii) of this
paragraph (b);

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

(xiv) Indebtedness consisting of the financing of insurance premiums in customary
amounts consistent with the operations and business of the Company and its Restricted
Subsidiaries; and

(xv) Indebtedness of the Company or any Restricted Subsidiary in addition to that
described in clauses (i) through (xiv) above, and any renewals, extensions, substitutions,
refinancings or replacements of such Indebtedness, so long as the aggregate principal amount
of all such Indebtedness outstanding at any one time in the aggregate shall not exceed the
greater of (x) $50.0 million and (y) 5.0% of Adjusted Consolidated Net Tangible Assets,
determined as of the date of the incurrence of such Indebtedness.

(c) For purposes of determining compliance with this Section 4.07, in the event that an item
of Indebtedness meets the criteria of more than one of the types of Indebtedness permitted by this
Section 4.07, the Company in its sole discretion shall classify or reclassify such item of
Indebtedness and only be required to include the amount of such Indebtedness as one of such types
(or to divide such Indebtedness between two or more of such types); provided that Indebtedness
under the Senior Credit Agreement, if any, which is in existence immediately following the issuance
of the Initial Notes, and any renewals, extensions, substitutions, refundings, refinancings or
replacements thereof, in an amount not in excess of the amount permitted to be incurred pursuant to
clause (i) of paragraph (b) above, shall be deemed to have been incurred pursuant to clause (i) of
paragraph (b) above rather than paragraph (a) above or any other clause of paragraph (b) above.

(d) Indebtedness permitted by this Section 4.07 need not be permitted solely by reference to
one provision permitting such Indebtedness but may be permitted in part by one such provision and
in part by one or more other provisions of this Section 4.07 permitting such Indebtedness.

(e) Accrual of interest, accretion or amortization of original issue discount and the payment
of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the
accretion or payment of dividends on any Disqualified Stock or Preferred Stock in the form of
additional shares of the same class of Disqualified Stock or Preferred Stock will not be deemed to
be an incurrence of Indebtedness for purposes of this Section 4.07; provided, in
each such case, that the amount thereof as accrued shall be included as required in the
calculation of the Consolidated Fixed Charge Coverage Ratio of the Company.

 

62

 

(f) For purposes of determining compliance with any dollar-denominated restriction on the
incurrence of Indebtedness denominated in a foreign currency, the dollar-equivalent principal
amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant
currency exchange rate in effect on the date that such Indebtedness was incurred.

(g) If Indebtedness is secured by a letter of credit that serves only to secure such
Indebtedness, then the total amount deemed incurred shall be equal to the greater of (i) the
principal of such Indebtedness and (ii) the amount that may be drawn under such letter of credit.

(h) The amount of Indebtedness issued at a price less than the amount of the liability thereof
shall be determined in accordance with GAAP.

Section 4.08. Restricted Payments.

(a) The Company shall not, and shall not cause or permit any Restricted Subsidiary to,
directly or indirectly:

(i) pay any dividend on, or make any distribution to holders of, any shares of the

Income of the Company accrued on a cumulative basis during the period
beginning on the first day of the Company’s fiscal quarter beginning after
the date of this Indenture and ending on the last day of the Company’s last
fiscal quarter ending prior to the date of the Restricted Payment (or, if
such aggregate cumulative Consolidated Net Income shall be a loss, minus
100% of such loss);

constituting a Restricted Payment (including any Investment in an
Unrestricted Subsidiary) made after the date of this Indenture, an amount
(to the extent not included in Consolidated Net Income) equal to the amount

redesignation; and

(6) any amount which previously qualified as a Restricted Payment on
account of any guarantee entered into by the Company or any Restricted

(b) Notwithstanding the foregoing, and in the case of clauses (ii) through (x) below, so long
as no Default or Event of Default is continuing or would arise therefrom, the foregoing provisions
shall not prohibit the following actions (each action described in clauses (i) through (x) being

excluded from clause (C)(2) of paragraph (a) of this Section 4.08;

 

65

 

(iii) the purchase, repurchase, redemption, defeasance, satisfaction and discharge,

repurchases, redemptions, retirements and acquisitions pursuant to this clause (vi) will
not, in the aggregate, exceed $2.0 million per fiscal year;

(vii) loans made to officers, directors or employees of the Company or any Restricted

purchase, exchange or lease of assets, property or services) with or for the benefit of any
Affiliate of the Company (other than the Company or a Restricted Subsidiary) involving aggregate
consideration in excess of $2.0 million unless such Transaction is entered into in good faith and
in writing and

(i) such Transaction is on terms that are no less favorable to the Company or such
Restricted Subsidiary, as the case may be, than those that would be available in a
comparable transaction in arm’s-length dealings with a party that is not an Affiliate of the
Company,

million,

(A) the Company delivers an Officers’ Certificate to the Trustee certifying

that such director or directors abstain from voting as a director of the Company or the
Restricted Subsidiary, as applicable, in connection with the approval of the Transaction.

Section 4.10. Liens.

(a) The Company shall not, and shall not cause or permit any Restricted Subsidiary to,
directly or indirectly, create or incur, in order to secure any Indebtedness, any Lien of any kind,

Company or any Restricted Subsidiary owned on the date of this Indenture or acquired after the date
of this Indenture, or assign or convey, in order to secure any Indebtedness, any
right to receive any income or profits therefrom, unless the Notes (or a Guarantee in the case
of Liens of a Guarantor) are directly secured equally and ratably with (or, in the case of
Subordinated Indebtedness, prior or senior thereto, with the same relative priority as the Notes
shall have with respect to such Subordinated Indebtedness) the Indebtedness secured by such Lien.

 

68

 

(b) Notwithstanding the foregoing, any Lien securing the Notes or a Guarantee granted pursuant
to paragraph (a) above shall be automatically and unconditionally released and discharged upon:
(i) the release of all other Liens that require the grant of Liens to secure the Notes or
Guarantees pursuant to the preceding paragraph, (ii) any sale, exchange or transfer to any Person
not an Affiliate of the Company of the property or assets secured by such Lien, (iii) any sale,
exchange or transfer to any Person not an Affiliate of the Company of all of the Capital Stock held
by the Company or any Restricted Subsidiary in, or all or substantially all the assets of, any
Restricted Subsidiary creating such Lien, or (iv) with respect to any Lien securing a Guarantee,
the release of such Guarantee in accordance with this Indenture.

Section 4.11. Asset Sales.

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, consummate any
Asset Sale unless (i) the Company or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets
and property subject to such Asset Sale and (ii) (A) at least 75% of the consideration paid to the
Company or such Restricted Subsidiary in connection with such Asset Sale is in the form of cash,
Cash Equivalents, Liquid Securities, Exchanged Properties (including pursuant to asset swaps) or
the assumption by the purchaser of liabilities of the Company (other than liabilities of the
Company that are by their terms subordinated to the Notes) or liabilities of any Guarantor that
made such Asset Sale (other than liabilities of a Guarantor that are by their terms subordinated to
such Guarantor’s Guarantee), in each case as a result of which the Company and its remaining
Restricted Subsidiaries are no longer liable for such liabilities (“Permitted
Consideration”) or (B) the Fair Market Value of all forms of such consideration other than
Permitted Consideration since the date of this Indenture does not exceed in the aggregate 10% of
the Adjusted Consolidated Tangible Assets of the Company at the time when each determination is
made.

(b) During the 365 days after the receipt by the Company or a Restricted Subsidiary of Net
Available Cash from an Asset Sale, such Net Available Cash may be applied by the Company or such
Restricted Subsidiary, to the extent the Company or such Restricted Subsidiary elects (or is
required by the terms of any Pari Passu Indebtedness of the Company or a Restricted Subsidiary),
to:

(i) repay (or cash-collateralize) Indebtedness of the Company under any Credit Facility
(excluding (i) any Subordinated Indebtedness and (ii) any Indebtedness owed to the Company
or an Affiliate of the Company);

(ii) reinvest in Additional Assets (including by means of an Investment in Additional
Assets by a Restricted Subsidiary with Net Available Cash received by the
Company or another Restricted Subsidiary) or make capital expenditures in the Oil and
Gas Business; or

 

69

 

(iii) purchase Notes, or purchase or repay on a permanent basis other Indebtedness
(excluding (A) any Subordinated Indebtedness and (B) any Notes or other Indebtedness owed to
the Company or an Affiliate of the Company).

provided that the Company or the applicable Restricted Subsidiary will be deemed to have complied
with clause (ii) of this paragraph (b) with respect to an Asset Sale if, within 365 days after such
Asset Sale, the Company or such Restricted Subsidiary shall have commenced and not completed or
abandoned an expenditure or Investment, or a binding agreement with respect to an expenditure or
Investment, in compliance with such clause (ii), and that expenditure or Investment is
substantially completed within one year and six months after the date of such Asset Sale. Pending
the final application of any such Net Available Cash, the Company may temporarily reduce
Indebtedness under any Credit Facility or otherwise expend or invest such Net Available Cash in any
manner that is not prohibited by this Indenture.

(c) Any Net Available Cash from an Asset Sale not applied in accordance with paragraph (b)
above within 365 days from the date of such Asset Sale shall constitute “Excess Proceeds.”
When the aggregate amount of Excess Proceeds exceeds $25.0 million, the Company will be required to
make an offer to purchase Notes having an aggregate principal amount equal to the aggregate amount
of Excess Proceeds (the “ Prepayment Offer”) at a purchase price (the “Prepayment Offer
Price”) equal to 100% of the principal amount of such Notes plus accrued and unpaid interest,
if any, to the Asset Sale Purchase Date (as defined in paragraph (d) below) in accordance with the
procedures (including prorating in the event of over subscription) set forth in this Indenture,
but, if the terms of any Pari Passu Indebtedness require that a Pari Passu Offer be made
contemporaneously with the Prepayment Offer, then the Excess Proceeds shall be prorated between the
Prepayment Offer and such Pari Passu Offer in accordance with the aggregate outstanding principal
amounts of the Notes and such Pari Passu Indebtedness, and the aggregate principal amount of Notes
for which the Prepayment Offer is made shall be reduced accordingly. If the aggregate principal
amount of Notes tendered by Holders thereof exceeds the amount of available Excess Proceeds, then
such Excess Proceeds will be allocated pro rata according to the principal amount of the Notes
tendered and the Trustee will select the Notes to be purchased in accordance with this Indenture.
To the extent that any portion of the amount of Excess Proceeds remains after compliance with the
second sentence of this paragraph (c) and provided that all Holders of Notes have been given the
opportunity to tender their Notes for purchase as described in paragraph (d) below in accordance
with this Indenture, the Company and its Restricted Subsidiaries may use such remaining amount for
purposes permitted by this Indenture and the amount of Excess Proceeds will be reset to zero.

(d) Within 30 days after the 365th day following the date of an Asset Sale, the Company shall,
if it is obligated to make an offer to purchase the Notes pursuant to paragraph (c) above, send a
written Prepayment Offer notice, by first-class mail, to the Holders of the Notes (the “
Prepayment Offer Notice”), with a copy to the Trustee, accompanied by such information
regarding the Company and its Subsidiaries as the Company believes will enable such Holders of the
Notes to make an informed decision with respect to the Prepayment Offer. The Prepayment Offer
Notice will state, among other things:

(i) that the Company is offering to purchase Notes pursuant to the provisions of this
Indenture;

(ii) that any Note (or any portion thereof) accepted for payment (and duly paid on the
Asset Sale Purchase Date) pursuant to the Prepayment Offer shall cease to accrue interest on
the Asset Sale Purchase Date;

(iii) that any Notes (or portions thereof) not properly tendered will continue to
accrue interest;

(iv) the purchase price and purchase date, which shall be, subject to any contrary
requirements of applicable law, no less than 30 days nor more than 60 days after the date
the Prepayment Offer Notice is mailed (the “Asset Sale Purchase Date”);

(v) the amount of Excess Proceeds available to purchase Notes;

(vi) a description of the procedure which Holders of Notes must follow in order to
tender their Notes and the procedures that Holders of Notes must follow in order to withdraw
an election to tender their Notes for payment; and

(vii) all other instructions and materials necessary to enable Holders to tender Notes
pursuant to the Prepayment Offer.

(e) If the Company becomes obligated to make a Prepayment Offer pursuant to clause (c) above,
the Notes and the Pari Passu Indebtedness shall be purchased by the Company, at the option of the
holders thereof, in whole or in part in amounts of $1,000 or whole multiples of $1,000 in excess
thereof, on the Asset Sale Purchase Date.

(f) The Company shall comply, to the extent applicable, with the requirements of Rule 14e-1
under the Exchange Act and any other securities laws or regulations thereunder to the extent such
laws and regulations are applicable in connection with the purchase of Notes as described above. To
the extent that the provisions of any securities laws or regulations conflict with the provisions
relating to the Prepayment Offer, the Company will comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations under this Section 4.11 by
virtue thereof.

(g) Holders electing to have Notes purchased hereunder will be required to surrender such
Notes at the address specified in the notice prior to the Asset Sale Purchase Date. Holders will be
entitled to withdraw their election to have their Notes purchased pursuant to this Section 4.11 if
the Company receives, not later than one Business Day prior to the Asset Sale Purchase Date, a
telegram, telex, facsimile transmission or letter setting forth (i) the name of the Holder, (ii)
the certificate number of the Note in respect of which such notice of withdrawal is being
submitted, (iii) the principal amount of the Note (which shall be $1,000 or whole multiples of
$1,000 in excess thereof) delivered for purchase by the Holder as to which his election is to be
withdrawn, (iv) a statement that such Holder is withdrawing his election to have such principal
amount of such Note purchased, and (v) the principal amount, if any, of such Note (which shall be
$1,000 or whole multiples of $1,000 in excess thereof) that remains subject to the original
Prepayment Offer Notice and that has been or will be delivered for purchase by the Company.

(h) The Company shall (i) not later than the Asset Sale Purchase Date accept for payment Notes
or portions thereof tendered pursuant to the Prepayment Offer, (ii) not later than 10:00 a.m. (New
York time) on the Asset Sale Purchase Date deposit with the Trustee or with a Paying Agent an
amount of money in same day funds sufficient to pay the aggregate Prepayment Offer Price, as the
case may be, of all the Notes or portions thereof which are to be purchased on that date and (iii)
not later than 10:00 a.m. (New York time) on the Asset Sale Purchase Date, as the case may be,
deliver to the Paying Agent an Officers’ Certificate stating the Notes or portions thereof accepted
for payment by the Company. The Paying Agent shall promptly mail or deliver to Holders of Notes so
accepted payment in an amount equal to the Prepayment Offer Price of the Notes purchased from each
such Holder, and the Company shall execute and the Trustee shall promptly authenticate and mail or
deliver to such Holders a new Note equal in principal amount to any unpurchased portion of the Note
surrendered. Any Notes not so accepted shall be promptly mailed or delivered by the Paying Agent at
the Company’s expense to the Holder thereof. For purposes of this Section 4.11, the Company shall
choose a Paying Agent which shall not be the Company.

Subject to applicable escheat laws, the Trustee and the Paying Agent shall return to the
Company any cash that remains unclaimed, together with interest, if any, thereon (subject to
Section 7.01(f)), held by them for the payment of the Prepayment Offer Price, as the case may be;
provided that (x) to the extent that the aggregate amount of cash deposited by the Company with the
Trustee in respect of a Prepayment Offer, as the case may be, exceeds the aggregate Prepayment
Offer Price of the Notes or portions thereof to be purchased, then the Trustee shall hold such
excess for the Company and (y) unless otherwise directed by the Company in writing, promptly after
the Business Day following the Asset Sale Purchase Date, as the case may be, the Trustee shall
return any such excess to the Company together with interest or dividends, if any, thereon (subject
to Section 7.01(f)).

(i) Notes to be purchased shall, on the Asset Sale Purchase Date, become due and payable at
the Prepayment Offer Price, as the case may be, and from and after such date (unless the Company
shall default in the payment of the Prepayment Offer Price) such Notes shall cease to bear
interest. Such Prepayment Offer Price shall be paid to such Holder promptly following the later of
the Asset Sale Purchase Date and the time of delivery of such Note to the relevant Paying Agent at
the office of such Paying Agent by the Holder thereof in the manner required. Upon surrender of any
such Note for purchase in accordance with the foregoing provisions, such Note shall be paid by the
Company at the Prepayment Offer Price; provided that installments of interest whose Stated Maturity
is on or prior to the Asset Sale Purchase Date shall be payable to the Person in whose name the
Notes are registered as such on the relevant record dates according to the terms and the provisions
of Section 2.04; and provided further that Notes to be purchased are subject to proration in the
event the Excess Proceeds are less than the aggregate Prepayment Offer Price of all Notes tendered
for purchase, with such adjustments as may be appropriate by the Trustee so that only Notes in
denominations of $1,000 or whole multiples of $1000 in excess thereof, shall be purchased. If any
Note tendered for purchase shall not be so paid upon surrender thereof by deposit of funds with the
Trustee or a Paying Agent in accordance with paragraph (i) above, the principal thereof (and
premium, if any, thereon) shall, until paid, bear interest from the Asset Sale Purchase Date at the
rate borne by such Note. Any Note that is to be purchased only in part shall be surrendered to a
Paying Agent at the office of such Paying Agent (with, if the Company, the Registrar or the Trustee
so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Registrar or the Trustee
duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the
Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note,
without service charge, one or more new Notes of any authorized denomination as requested by such
Holder in an aggregate principal amount equal to, and in exchange for, the portion of the principal
amount of the Note so surrendered that is not purchased. The Company shall publicly announce the
results of the Prepayment Offer, as the case may be, on or as soon as practicable after the Asset
Sale Purchase Date.

Section 4.12. Issuances of Guarantees by Restricted Subsidiaries.

(a) The Company shall provide to the Trustee, on or prior to the 30th day after the date that
(i) any Person becomes a direct or indirect domestic Restricted Subsidiary after the date of this
Indenture, (ii) any Unrestricted Subsidiary is redesignated as a Restricted Subsidiary, or (iii)
any Restricted Subsidiary of the Company (which is not a Guarantor) becomes a guarantor or obligor
in respect of any Indebtedness of the Company or any of the Restricted Subsidiaries in an aggregate
principal amount exceeding $5.0 million, in each case, a supplemental indenture to this Indenture
substantially in the form of Exhibit F hereto, executed by such Restricted Subsidiary,
providing for a full and unconditional guarantee on a senior unsecured basis by such Restricted
Subsidiary of the Company’s obligations under the Notes and this Indenture to the same extent as
that set forth in this Indenture.

such supplemental indenture unless such Foreign Subsidiary has guaranteed other Indebtedness of the
Company or of a Restricted Subsidiary that is not a Foreign Subsidiary, and (ii) no Restricted
Subsidiary shall be required to execute any such supplemental indenture if the Consolidated Net
Worth of such Restricted Subsidiary, together with the Consolidated Net Worth of all other
Non-Guarantor Restricted Subsidiaries, as of such date, does not exceed in the aggregate $5.0
million. To the extent the collective Consolidated Net Worth of the Company’s Non-Guarantor
Restricted Subsidiaries, as of the date of the creation of, acquisition of or Investment in a
Non-Guarantor Restricted Subsidiary, exceeds $5.0 million, the Company shall cause, within 30 days
after such date, one or more of such Non-Guarantor Restricted Subsidiaries to similarly execute and
deliver to the Trustee a supplemental indenture to this Indenture substantially in the form of
Exhibit F hereto providing for a full and unconditional guarantee on a senior unsecured
basis by such Restricted Subsidiary of the Company’s obligations under the Notes and this Indenture
to the same extent as that set forth in this Indenture, such that the collective Consolidated Net
Worth of all remaining Non-Guarantor Restricted Subsidiaries does not exceed $5.0 million.

Section 4.13. Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

such Person becomes a Restricted Subsidiary of the Company and not incurred in connection
with, or in contemplation of, such Person becoming a Restricted Subsidiary, provided that
such encumbrances and restrictions are not applicable to the Company or any Restricted
Subsidiary or the properties or assets of the Company or any Restricted Subsidiary other
than such Subsidiary which is becoming a Restricted Subsidiary;

(iii) any agreement or instrument governing any Acquired Debt or other agreement of any
entity or related to assets acquired by or merged into or consolidated with the Company or
any Restricted Subsidiaries, so long as such encumbrance or restriction (A) was not entered
into in contemplation of the acquisition, merger or consolidation transaction, and (B) is
not applicable to any Person, or the properties or assets of any Person, other than the
Person, or the property or assets or subsidiaries of the Person, so acquired, so long as the
agreement containing such restriction does not violate any other provision of this
Indenture;

(iv) any applicable law or any requirement of any regulatory body;

(v) the security documents evidencing any Liens securing obligations or Indebtedness or
agreements relating to Capital Lease Obligations (provided that such Liens are otherwise

the debtor or lessee to dispose of the assets subject to such Liens;

(vi) provisions restricting subletting or assignment of any lease governing a leasehold
interest of the Company or any Restricted Subsidiary, or restrictions in licenses relating
to the property covered thereby, or other encumbrances or restrictions in agreements or
instruments relating to specific assets or property that restrict generally the transfers of
such assets or property, provided that such encumbrances or restrictions do
not materially impact the ability of the Company to permit payments on the Notes when
due as required by the terms of this Indenture;

 

74

 

(vii) asset sale agreements with respect to asset sales permitted to be made under the
provisions of Section 4.11 hereof that limit the transfer of such assets pending the closing
of such sale;

(viii) shareholders’, partnership, joint venture and similar agreements entered into in
the ordinary course of business; provided that such encumbrances or restrictions do not
apply to any Restricted Subsidiaries other than the applicable company, partnership, joint
venture or other entity; and provided further that such encumbrances and restrictions do not
materially impact the ability of the Company to permit payments on the Notes when due as
required by the terms of this Indenture;

contained in the Senior Credit Agreement as in effect on the date of this Indenture;

(xi) restrictions of the nature described in clause (iv) of the preceding paragraph (a)
by reason of customary non-assignment provisions in contracts, agreements, licenses and
leases entered into in the ordinary course of business; or

refunding, replacement or refinancing that extends, renews, refinances or replaces the
agreements containing the encumbrances or restrictions in the foregoing clauses (i) through

encumbrances or restrictions are no more restrictive in any material respect taken as a
whole than those under or pursuant to the agreement so extended, renewed, refinanced or
replaced.

Section 4.14. Sale Leaseback Transactions.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, enter into
any Sale Leaseback Transaction; provided, that the Company or any of its Restricted Subsidiaries
may enter into a Sale Leaseback Transaction if:

Attributable Indebtedness relating to such Sale Leaseback Transaction pursuant to the Consolidated
Fixed Charge Coverage Ratio test set forth in paragraph (a) of Section 4.07 hereof;

Section 4.15. Lines of Business.

Neither the Company nor any of its Restricted Subsidiaries will directly or indirectly engage
in any line or lines of business activity other than that which is an Oil and Gas Business, except
to such extent as would not be material to the Company and its Restricted Subsidiaries taken as a
whole.

Section 4.16. Corporate Existence.

Subject to Article Five, the Company shall do or cause to be done all things necessary to
preserve and keep in full force and effect the corporate existence, rights (charter and statutory)
and franchises of the Company and each Subsidiary; provided that the Company shall not be required
to preserve any such right or franchise or to preserve the existence of any Subsidiary or any right
or franchise of the Company or any Subsidiary if the Company shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries
as a whole and that the loss thereof is not disadvantageous in any material respect to the Holders.

Section 4.17. Unrestricted Subsidiaries.

(a) The Board of Directors of the Company may designate after the Issue Date any Subsidiary as
an “Unrestricted Subsidiary” under this Indenture (a “Designation”) only if:

(i) no Default or Event of Default shall have occurred and be continuing at the time of
or after giving effect to such Designation;

(ii) (A) the Company would be permitted to make an Investment (other than a Permitted
Investment) at the time of Designation (assuming the effectiveness of such Designation)
pursuant to paragraph (a) of Section 4.08 hereof in an amount (the “Designation
Amount”) equal to the greater of (1) the net book value of the Company’s interest in
such Subsidiary calculated in accordance with GAAP or (2) the Fair Market Value of the
Company’s interest in such Subsidiary as determined in good faith by the Company’s Board of
Directors, or (B) the Designation Amount is less than $1,000;

(iii) such Unrestricted Subsidiary does not own any Capital Stock in any Restricted
Subsidiary of the Company which is not simultaneously being designated an Unrestricted
Subsidiary;

 

76

 

(iv) such Unrestricted Subsidiary is not liable, directly or indirectly, with respect
to any Indebtedness other than Unrestricted Subsidiary Indebtedness, provided that an
Unrestricted Subsidiary may provide a Guarantee for the Notes; and

(v) such Unrestricted Subsidiary is not a party to any agreement, contract, arrangement
or understanding at such time with the Company or any Restricted Subsidiary unless the terms
of any such agreement, contract, arrangement or understanding are no less favorable to the
Company or such Restricted Subsidiary than those that might be obtained at the time from
Persons who are not Affiliates of the Company or, in the event such condition is not
satisfied, the value of such agreement, contract, arrangement or understanding to such
Unrestricted Subsidiary shall be deemed a Restricted Payment.

(b) In the event of any such Designation, the Company shall be deemed, for all purposes of
this Indenture, to have made an Investment equal to the Designation Amount that constitutes a
Restricted Payment pursuant to Section 4.08 hereof.

(c) The Company shall not and shall not cause or permit any Restricted Subsidiary to at any
time

(i) provide credit support for, guarantee or subject any of its property or assets
(other than the Capital Stock of any Unrestricted Subsidiary) to the satisfaction of, any
Indebtedness of any Unrestricted Subsidiary (including any undertaking, agreement or
instrument evidencing such Indebtedness) or enter into or become a party to any agreement,
contract, arrangement or understanding with any Unrestricted Subsidiary, the terms of which,
together with the terms of all other agreements, contracts, arrangements and understandings
with such Unrestricted Subsidiary, taken as a whole, in the good-faith judgment of the Board
of Directors of the Company, are less favorable to the Company and its Restricted
Subsidiaries than those that would be available in a comparable transaction in arm’s-length
dealings with a party that is not an Affiliate of the Company; provided that this Section
4.17 shall not be deemed to prevent Permitted Investments in Unrestricted Subsidiaries that
are otherwise allowed under this Indenture, or

(ii) be directly or indirectly liable for any Indebtedness of any Unrestricted
Subsidiary.

(d) For purposes of the foregoing, the Designation of a Subsidiary of the Company as an
Unrestricted Subsidiary shall be deemed to be the Designation of all of the Subsidiaries of such
Subsidiary as Unrestricted Subsidiaries. Unless so designated as an Unrestricted Subsidiary, any
Person that becomes a Subsidiary of the Company will be classified as a Restricted Subsidiary.

(e) The Company may revoke any Designation of a Subsidiary as an Unrestricted Subsidiary (a
“Revocation”) if:

(i) no Default or Event of Default shall have occurred and be continuing at the time of
and after giving effect to such Revocation;

 

77

 

(ii) all Indebtedness of such Unrestricted Subsidiary outstanding immediately following
such Revocation would, if incurred at such time, have been permitted to be incurred for all
purposes of this Indenture; and

(iii) unless such redesignated Subsidiary shall not have any Indebtedness outstanding
(other than Indebtedness that would be Permitted Debt), immediately after giving effect to
such proposed Revocation, and after giving pro forma effect to the incurrence of any such
Indebtedness of such redesignated Subsidiary as if such Indebtedness was incurred on the
date of the Revocation, the Company could incur $1.00 of additional Indebtedness (other than
Permitted Debt) pursuant to Section 4.07 hereof.

(f) All Designations and Revocations must be evidenced by a Board Resolution of the Board of
Directors of the Company delivered to the Trustee certifying compliance with the foregoing
provisions of this Section 4.17.

Section 4.18. Payments for Consent.

Neither the Company nor any of its Restricted Subsidiaries shall, directly or indirectly, pay
or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder
of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or
provisions of this Indenture or the Notes unless such consideration is offered to be paid or is
paid to all Holders of Notes that consent, waive or agree to amend in the time frame set forth in
the solicitation documents relating to such consent, waiver or agreement.

Section 4.19. Offer to Repurchase upon a Change of Control.

(a) If a Change of Control occurs, each Holder of Notes shall have the right to require that
the Company purchase all or any part (in amounts of $1,000 or whole multiples of $1,000 in excess
thereof) of such Holder’s Notes pursuant to the offer described below (the “Change of Control
Offer”). In the Change of Control Offer, the Company shall offer to purchase all of the Notes,
at a purchase price (the “Change of Control Purchase Price”) in cash in an amount equal to
101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to the date
of purchase (the “Change of Control Purchase Date”) (subject to the rights of holders of
record on relevant record dates to receive interest due on an interest payment date).

(b) Within 30 days after any Change of Control or, at the Company’s option, prior to such
Change of Control but after it is publicly announced, the Company must notify the Trustee and give
written notice of the Change of Control (the “Change of Control Purchase Notice”) to each
Holder of Notes, by first-class mail, postage prepaid, at his address appearing in the security
register. The Change of Control Purchase Notice must state, among other things:

(i) that a Change of Control has occurred or will occur and the date of such event;

(ii) the circumstances and relevant facts regarding such Change of Control;

 

78

 

(iii) the Change of Control Purchase Price and the Change of Control Purchase Date,
which shall be fixed by the Company on a Business Day no earlier than 30 days nor
later than 60 days from the date the notice is mailed, or such later date as is
necessary to comply with requirements under the Exchange Act; provided that the Change of
Control Purchase Date may not occur prior to the Change of Control;

(iv) that any Note not tendered will continue to accrue interest;

(v) that, unless the Company defaults in the payment of the Change of Control Purchase
Price, any Notes accepted for payment pursuant to the Change of Control Offer shall cease to
accrue interest after the Change of Control Purchase Date; and

(vi) other procedures that a Holder of Notes must follow to accept a Change of Control
Offer or to withdraw acceptance of the Change of Control Offer.

Any Change of Control Offer that is made prior to the occurrence of a Change of Control may at the
Company’s discretion be subject to one or more conditions precedent, including but not limited to
the occurrence of a Change of Control.

(c) Upon receipt by the Company of the proper tender of Notes, the Holder of the Note in
respect of which such proper tender was made shall (unless the tender of such Note is properly
withdrawn at least one Business Day prior to the Change of Control Purchase Date) thereafter be
entitled to receive solely the Change of Control Purchase Price with respect to such Notes. Upon
surrender of any such Note for purchase in accordance with the foregoing provisions, such Note
shall be paid by the Company at the Change of Control Purchase Price; provided that installments of
interest whose Stated Maturity is on or prior to the Change of Control Purchase Date shall be
payable to the Holders of such Notes, registered as such on the relevant Regular Record Dates
according to the terms and the provisions of Section 2.03. If any Note tendered for purchase in
accordance with the provisions of this Section 4.19 shall not be so paid upon surrender thereof,
the principal thereof (and premium, if any, thereon) shall, until paid, bear interest from the
Change of Control Purchase Date at the rate borne by such Note. Holders electing to have Notes
purchased will be required to surrender such Notes to the Paying Agent at the address specified in
the Change of Control Purchase Notice at least one Business Day prior to the Change of Control
Purchase Date. Any Note that is to be purchased only in part shall be surrendered to a Paying Agent
at the office of such Paying Agent (with, if the Company, the Registrar or the Trustee so require,
due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the
Registrar or the Trustee, as the case may be, duly executed by, the Holder thereof or such Holder’s
attorney duly authorized in writing), and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Note, without service charge, one or more new Notes
of any authorized denomination as requested by such Holder in an aggregate principal amount equal
to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not
purchased.

 

79

 

(d) The Company shall (i) not later than the Change of Control Purchase Date, accept for
payment Notes or portions thereof tendered pursuant to the Change of Control Offer, (ii) not later
than 10:00 a.m. (New York time) on the Business Day following the Change of Control Purchase Date,
deposit with the Trustee or with a Paying Agent an amount of money in same day funds sufficient to
pay the aggregate Change of Control Purchase Price of all the Notes or portions thereof which have
been so accepted for payment and (iii) not later than 10:00 a.m.
(New York time) on the Business Day following the Change of Control Purchase Date, deliver to
the Paying Agent an Officers’ Certificate stating the Notes or portions thereof accepted for
payment by the Company. The Paying Agent shall promptly mail or deliver to Holders of Notes so
accepted payment in an amount equal to the Change of Control Purchase Price of the Notes purchased
from each such Holder, and the Company shall execute and the Trustee shall promptly authenticate
and mail or deliver to such Holders a new Note equal in principal amount to any unpurchased portion
of the Note surrendered. Any Notes not so accepted shall be promptly mailed or delivered by the
Paying Agent at the Company’s expense to the Holder thereof. The Company will publicly announce the
results of the Change of Control Offer on the Change of Control Purchase Date. For purposes of this
Section 4.19, the Company shall choose a Paying Agent which shall not be the Company.

(e) A tender made in response to a Change of Control Purchase Notice may be withdrawn if the
Company receives, not later than one Business Day prior to the Change of Control Purchase Date, a
telegram, telex, facsimile transmission or letter, specifying, as applicable:

(i) the name of the Holder;

(ii) the certificate number of the Note in respect of which such notice of withdrawal
is being submitted;

(iii) the principal amount of the Note (which shall be $1,000 or whole multiples of
$1,000 in excess thereof) delivered for purchase by the Holder as to which such notice of
withdrawal is being submitted;

(iv) a statement that such Holder is withdrawing his election to have such principal
amount of such Note purchased; and

(v) the principal amount, if any, of such Note (which shall be $1,000 or whole
multiples of $1,000 in excess thereof) that remains subject to the original Change of
Control Purchase Notice and that has been or will be delivered for purchase by the Company.

(f) Subject to applicable escheat laws, the Trustee and the Paying Agent shall return to the
Company any cash that remains unclaimed, together with interest or dividends, if any, thereon
(subject to Section 7.01(f) hereof), held by them for the payment of the Change of Control Purchase
Price; provided that (i) to the extent that the aggregate amount of cash deposited by the Company
pursuant to clause (ii) of paragraph (d) above exceeds the aggregate Change of Control Purchase
Price of the Notes or portions thereof to be purchased, then the Trustee shall hold such excess for
the Company and (ii) unless otherwise directed by the Company in writing, promptly after the
Business Day following the Change of Control Purchase Date the Trustee shall return any such excess
to the Company together with interest, if any, thereon (subject to Section 7.01(f) hereof).

(g) The Company shall comply with the applicable tender offer rules, including Rule 14e-1
under the Exchange Act, and any other applicable securities laws or regulations in connection with
a Change of Control Offer. To the extent that the provisions of any securities
laws or regulations conflict with this Section 4.19, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have breached its obligations
under this Section 4.19 by virtue of such conflict.

 

80

 

(h) Notwithstanding the foregoing, the Company shall not be required to make a Change of
Control Offer (i) upon a Change of Control if a third party makes the Change of Control Offer in
the manner, at the times and otherwise in compliance with the requirements set forth in this
Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes
validly tendered and not withdrawn under such Change of Control Offer or (ii) if notice of
redemption for 100% of the aggregate principal amount of the outstanding Notes has been given
pursuant to Section 3.07 hereof, unless and until there is a default in payment of the applicable
redemption price.

(i) If holders of not less than 90% of the aggregate principal amount of the outstanding Notes
accept a Change of Control Offer and the Company purchases all of the Notes held by such holders,
the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given
not more than 30 days following the purchase pursuant to the Change of Control Offer described
above, to redeem all of the Notes that remain outstanding following such purchase at a redemption
price equal to 101% of the aggregate principal amount of the Notes redeemed plus accrued and unpaid
interest, if any, thereon to the date of redemption, subject to the right of the holders of record
on relevant record dates to receive interest due on an interest payment date.

Section 4.20. Covenant Termination.

If at any time (a) the rating assigned to the Notes by both S&P and Moody’s is at least an
Investment Grade Rating, (b) the obligations under the Senior Credit Agreement cease to be secured
and (c) no Default has occurred and is continuing under this Indenture, then upon delivery to the
Trustee of an Officers’ Certificate to the foregoing effect, the Company and its Restricted
Subsidiaries will no longer be subject to the provisions of Sections 4.07, 4.08, 4.09, 4.11, 4.13,
4.15, clauses (a) and (c) of Section 4.14 and the financial test set forth in clause (iii) in

series of transactions, in the aggregate, would result in a sale, assignment, conveyance, transfer,
lease or disposition of all or substantially all of the properties and assets of the Company and
its Restricted Subsidiaries on a Consolidated basis to any other Person or group of Persons, unless
at the time and after giving effect thereto:

(i) either (A) the Company will be the continuing corporation or (B) the Person (if
other than the Company) formed by such consolidation or into which the Company is merged or
the Person which acquires by sale, assignment, conveyance, transfer, lease or disposition
all or substantially all of the properties and assets of the Company and its Restricted
Subsidiaries on a Consolidated basis (the “Surviving Entity”) will be a corporation,
limited liability company or limited partnership (provided that in the event the Surviving
Entity is a limited partnership, then a Subsidiary of the Surviving Entity that is a
corporation or limited liability company shall execute a supplemental indenture pursuant to
which it shall become a co-obligor of the Surviving Entity’s obligations under the Notes and
this Indenture) duly organized and validly existing under the laws of the United States of
America, any state thereof or the District of Columbia and such Person expressly assumes, by
a supplemental indenture, in a form reasonably satisfactory to the Trustee, all the
obligations of the Company under the Notes and this Indenture, and the Notes and this
Indenture will remain in full force and effect as so supplemented (and any Guarantees will
be confirmed as applying to such Surviving Entity’s obligations);

(ii) except in the case of a merger of the Company with or into a Guarantor,
immediately after giving effect to such transaction on a pro forma basis (and treating any
Indebtedness not previously an obligation of the Company or any of its Restricted
Subsidiaries which becomes the obligation of the Company or any of its Restricted
Subsidiaries as a result of such transaction as having been incurred at the time of such
transaction), no Default or Event of Default will have occurred and be continuing;

(iii) except in the case of a merger of the Company with or into a Guarantor,
immediately after giving effect to such transaction on a pro forma basis (on the assumption
that the transaction occurred on the first day of the four-quarter period for which
financial statements are available ending immediately prior to the consummation of such
transaction with the appropriate adjustments with respect to the transaction being included
in such pro forma calculation), the Company (or the Surviving Entity if the Company is not
the continuing obligor under this Indenture) could on the first day following such
four-quarter period incur $1.00 of additional Indebtedness (other than Permitted Debt) under
Section 4.07 hereof;

(iv) at the time of the transaction, each Guarantor, if any, unless it is the other
party to the transactions described above, will have by supplemental indenture confirmed
that its Guarantee shall apply to such Person’s obligations under this Indenture and the
Notes;

(v) at the time of the transaction, if any of the property or assets of the Company or
any of its Restricted Subsidiaries would thereupon become subject to any Lien, Section 4.10
hereof is complied with; and

(vi) at the time of the transaction, the Company or the Surviving Entity will have
delivered, or caused to be delivered, to the Trustee, in form and substance reasonably
satisfactory to the Trustee, an Officers’ Certificate and an Opinion of Counsel, each to the
effect that such consolidation, merger, transfer, sale, assignment, conveyance,
transfer, lease or other transaction and the supplemental indenture in respect thereof
comply with this Indenture.

 

82

 

(b) Except as provided under Section 10.04 hereof, each Guarantor will not, and the Company
will not permit a Guarantor to, in a single transaction or through a series of related
transactions, (x) consolidate with or merge with or into any other Person (other than the Company
or any other Guarantor) or (y) sell, assign, convey, transfer, lease or otherwise dispose of all or
substantially all of its properties and assets to any Person or group of Persons (other than the
Company or any other Guarantor) or permit any of its Restricted Subsidiaries to enter into any such
transaction or series of transactions if such transaction or series of transactions, in the
aggregate, in the case of clause (y) would result in a sale, assignment, conveyance, transfer,
lease or disposition of all or substantially all of the properties and assets of the Guarantor and
its Restricted Subsidiaries on a Consolidated basis to any other Person or group of Persons (other
than the Company or any Guarantor), unless at the time and after giving effect thereto:

(i) one of the following is true (A) the Guarantor or the Company will be the
continuing Person in the case of a consolidation or merger involving the Guarantor or (B)
the Person (if other than the Guarantor) formed by such consolidation or into which such
Guarantor is merged or the Person which acquires by sale, assignment, conveyance, transfer,
lease or disposition of all or substantially all of the properties and assets of the
Guarantor and its Restricted Subsidiaries on a Consolidated basis (the “Surviving
Guarantor Entity”) will be a corporation, limited liability company, limited liability
partnership, partnership, trust or other entity duly organized and validly existing under
the laws of the United States of America, any state thereof or the District of Columbia and
such Person expressly assumes, by a supplemental indenture, in a form reasonably
satisfactory to the Trustee, all the obligations of such Guarantor under its Guarantee of
the Notes and this Indenture, and such Guarantee and this Indenture will remain in full
force and effect or (C) the Transaction, at the time thereof, is effected in compliance with
Section 4.11 hereof, to the extent applicable thereto;

(ii) immediately before and immediately after giving effect to such transaction on a
pro forma basis, no Default or Event of Default will have occurred and be continuing; and

(iii) at the time of the transaction such Guarantor or the Surviving Guarantor Entity
will have delivered, or caused to be delivered, to the Trustee, in form and substance
reasonably satisfactory to the Trustee, an Officers’ Certificate and an Opinion of Counsel,
each to the effect that such consolidation, merger, transfer, sale, assignment, conveyance,
lease or other transaction and the supplemental indenture in respect thereof comply with
this Indenture;

provided that this paragraph (b) shall not apply to any Guarantor whose Guarantee of the Notes is
unconditionally released and discharged in accordance with Section 10.04 hereof.

 

83

 

(c) In the event of any transaction (other than a lease) described in and complying with the
conditions listed in paragraphs (a) and (b) above in which the Company or any Guarantor, as the
case may be, is not the continuing Person, the successor Person formed or
remaining or to which such transfer is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company or such Guarantor, as the case may be, and the
Company or any Guarantor, as the case may be, shall be discharged (other than in a transaction that
results in the transfer of assets constituting or accounting for less than 95% of the Consolidated
assets (as of the last balance sheet date available to the Company) of the Company or the
Consolidated revenue of the Company (as of the last 12-month period for which financial statements
are available)) from all obligations and covenants under this Indenture and the Notes or its
Guarantee, as the case may be.

(d) Notwithstanding the foregoing, the Company or any Guarantor may merge with an Affiliate
incorporated or organized solely for the purpose of reincorporating or reorganizing the Company or
Guarantor in another jurisdiction to realize tax or other benefits.

any applicable grace period and shall not have been cured or waived and, if not already
matured at its final maturity in accordance with its terms, the holder of such Indebtedness shall
have the right to accelerate such Indebtedness or (ii) an event of default as defined in any of the
agreements, indentures or instruments described in clause (i) of this clause (e) shall have
occurred and the Indebtedness thereunder, if not already matured at its final maturity in
accordance with its terms, shall have been accelerated;

(f) any Guarantee shall for any reason cease to be, or shall for any reason be asserted in
writing by any Guarantor or the Company not to be, in full force and effect and enforceable in
accordance with its terms, except to the extent contemplated by this Indenture and any such
Guarantee;

(g) one or more judgments, orders or decrees of any court or regulatory or administrative

property, or the making by it of an assignment for the benefit of creditors, or the admission by it
in writing of its inability to pay its debts generally as they become due.

 

85

 

Section 6.02. Acceleration.

(a) If an Event of Default (other than as specified in Section 6.01(h) or (i) above) shall
occur and be continuing with respect to this Indenture, the Trustee or the Holders of not less than
25% in aggregate principal amount of the Notes then outstanding may declare all unpaid principal
of, premium, if any, and accrued interest on all Notes to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by the Holders
of the Notes) and upon any such declaration, such principal, premium, if any, and interest
shall become due and payable immediately. If an Event of Default specified in Section 6.01(h) or
(i) above occurs and is continuing, then all the Notes shall ipso facto become due and payable
immediately in an amount equal to the principal amount of the Notes, together with accrued and
unpaid interest, if any, to the date the Notes become due and payable, without any declaration or
other act on the part of the Trustee or any Holder of Notes. Thereupon, the Trustee may, at its
discretion, proceed to protect and enforce the rights of the Holders of Notes by appropriate
judicial proceedings.

(b) After a declaration of acceleration, but before a judgment or decree for payment of the
money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount
of Notes outstanding by written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if:

(i) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all
sums paid or advanced by the Trustee under this Indenture and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, (B) all overdue
interest on all Notes then outstanding, (C) the principal of, and premium, if any, on any
Notes then outstanding which have become due otherwise than by such declaration of
acceleration and interest thereon at the rate borne by the Notes and (D) to the extent that
payment of such interest is lawful, interest upon overdue interest at the rate borne by the
Notes;

(ii) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction; and

(iii) all Events of Default, other than the non-payment of principal of, premium, if
any, and interest on the Notes which have become due solely by such declaration of
acceleration, have been cured or waived as provided in this Indenture.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

(c) Notwithstanding the preceding, if an Event of Default specified in Section 6.02(e) shall
have occurred and be continuing, such Event of Default and any consequential acceleration shall be
automatically rescinded if (i) the Indebtedness that is the subject of such Event of Default shall
have been repaid or (ii) if the default relating to such Indebtedness is waived or cured and if
such Indebtedness shall have been accelerated, the holders thereof have rescinded their declaration
of acceleration in respect of such Indebtedness.

Section 6.03. Other Remedies.

(a) If an Event of Default occurs and is continuing, the Trustee may pursue any available
remedy to collect the payment of principal, premium, if any, or interest on the Notes or to enforce
the performance of any provision of the Notes or this Indenture.

(b) The Trustee may maintain a proceeding even if it does not possess any of the Notes or does
not produce any of them in the proceeding. A delay or omission by the Trustee or
any Holder of a Note in exercising any right or remedy accruing upon and during the
continuance of an Event of Default shall not impair the right or remedy or constitute a waiver of
or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by
law.

 

86

 

Section 6.04. Waiver of Past Defaults.

The Holders of not less than a majority in aggregate principal amount of the Notes outstanding
may on behalf of the Holders of all outstanding Notes waive any past Default or Event of Default
under this Indenture and its consequences, except a Default or Event of Default (a) in the payment
of the principal of, premium, if any, or interest on any Note (which may only be waived with the
consent of each Holder of Notes affected) or (b) in respect of a covenant or provision which under
this Indenture cannot be modified or amended without the consent of the Holder of each Note
affected by such modification or amendment. The Company shall deliver to the Trustee an Officers’
Certificate stating that the requisite percentage of Holders have consented to such waiver and
attaching copies of such consents. In case of any such waiver, the Company, the Trustee and the
Holders shall be restored to their former positions and rights hereunder and under the Notes,
respectively. This Section 6.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and such
Section 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the Notes, as
permitted by the TIA. Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture;
but no such waiver shall extend to any subsequent or other Default or impair any right consequent
thereon.

Section 6.05. Control by Majority.

Holders of at least a majority in principal amount of the then outstanding Notes may direct
the time, method and place of conducting any proceeding for exercising any remedy available to the
Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow
any direction that conflicts with law or this Indenture or that the Trustee determines may be
unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in
personal liability. The Trustee may withhold from Holders of the Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their interest.

Section 6.06. Limitation on Suits.

(a) A Holder has a right to institute any proceeding with respect to this Indenture, or the
Notes or any Guarantees, only if:

(i) the Holder gives to the Trustee written notice of a continuing Event of Default;

(ii) the Holders of at least 25% in aggregate principal amount of the then outstanding
Notes make a written request to the Trustee to institute such proceeding;

 

87

 

(iii) such Holder of a Note or Holders of Notes offer and, if requested, provide to the
Trustee satisfactory indemnity against any loss, liability or expense that might be incurred
by it in connection with the request or direction;

(iv) the Trustee does not comply with the request within 60 days after receipt of the
request and the offer and, if requested, the provision of indemnity; and

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

(b) A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of
a Note or to obtain a preference or priority over another Holder of a Note.

Section 6.07. Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to
receive payment of principal, premium, if any, or interest on such Note, on or after the respective
due dates expressed in such Note (including in connection with an offer to purchase), 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(a) or (b) above occurs and is continuing, the
Trustee is authorized to recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount of overdue principal of, premium, if any, interest
remaining unpaid on the Notes and interest on overdue principal and premium, if any, and, to the
extent lawful, interest and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel.

Section 6.09. Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company
or any Guarantor (or any other obligor upon the Notes), its creditors or its property and shall be
entitled and empowered to collect, receive and distribute any money or other securities or property
payable or deliverable on any such claims and any custodian in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee, and in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee
any amount due to it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof.
To the extent that the payment of any such compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07
hereof out of the estate in any such

 

88

 

proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid
out of, any and all distributions, dividends, money, securities and other properties that the
Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of
reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any
Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding. The Trustee may, on behalf of the Holders, vote for the election of a trustee in
bankruptcy or similar official and be a member of a creditors’ or other similar committee.

Section 6.10. Priorities.

(a) If the Trustee collects any money or other property pursuant to this Article Six, it shall
pay out the money and other property in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof,
including payment of all compensation, expense and liabilities incurred, and all advances made, by
the Trustee and the costs and expenses of collection;

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium,
if any, interest ratably, without preference or priority of any kind, according to the amounts due
and payable on the Notes for principal, premium, if any, and interest, respectively; and

Third: to the Company or to such party as a court of competent jurisdiction shall direct.

(b) The Trustee may fix a record date and payment date for any payment to Holders of Notes
pursuant to this Section 6.10.

Section 6.11. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as a 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 and expenses, against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant. This Section does not apply to a suit
by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders
of more than ten percent in principal amount of the then outstanding Notes.

Notes are listed in accordance with TIA Section 313(d). The Company shall promptly notify the
Trustee when the Notes are listed on any stock exchange or any delisting thereof.

Section 7.07. Compensation and Indemnity.

(a) The Company shall pay to the Trustee (in its capacity as Trustee, and, to the extent it
has been appointed as such, as Paying Agent and Registrar) from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder in accordance with a
written schedule provided by the Trustee to the Company. 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 promptly upon request for all reasonable and customary disbursements, advances and
reasonable out-of-pocket expenses incurred or made by it in addition to the compensation for its
services, except those resulting from its own negligent action, negligent failure to act or willful
misconduct. Such expenses shall include the reasonable and customary compensation, disbursements
and expenses of the Trustee’s agents and counsel.

(b) The Company shall indemnify the Trustee in its capacity against any and all losses,
liabilities or reasonable out-of-pocket expenses incurred by it arising out of or in connection
with the acceptance or administration of its duties under this Indenture, including the costs and
expenses of enforcing this Indenture against the Company (including this Section 7.07) and
defending itself against any claim (whether asserted by either of the Company or any Holder or any
other person) or liability in connection with the exercise or performance of any of its powers or
duties hereunder, except to the extent any such loss, liability or expense may be attributable to
its negligence or bad faith. The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall
cooperate in the defense. The Trustee may elect to have separate counsel defend the claim, but the
Company will be obligated to pay the reasonable fees and expenses of such separate counsel only if
the Company fails to assume the Trustee’s defense or there is a conflict of interest between the
Company, on the one hand, and the Trustee, on the other hand, with respect to the claim, as
reasonably determined by the Trustee. The Company need not pay for any settlement made without its
consent, which consent shall not be unreasonably withheld.

(c) The obligations of the Company under this Section 7.07 shall survive the satisfaction and
discharge of this Indenture and the resignation or removal of the Trustee.

(d) To secure the Company’s payment obligations in this section, the Trustee shall have a Lien
prior to the Notes on all money or property held or collected by the Trustee, except that held in
trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction
and discharge of this Indenture.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified
in Section 6.01(h) or (i) hereof occurs, the expenses and the compensation for the services
(including the fees and expenses of its agents and counsel) are intended to constitute expenses of
administration under any Bankruptcy Law.

become effective only upon the successor Trustee’s acceptance of appointment as provided in this
Section 7.08.

(b) The Trustee may resign in writing at any time and be discharged from the trust hereby
created by so notifying the Company. The Holders of a majority in principal amount of the then
outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing.

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

(iii) a custodian or public officer takes charge of the Trustee or its property; or

(iv) the Trustee becomes incapable of acting.

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for
any reason, the Company shall promptly appoint a successor Trustee. Within one year after the
successor Trustee takes office, the Holders of a majority in principal amount of the then
outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

(d) If a successor Trustee does not take office within 30 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Company, or the Holders of Notes of at least 10%
in principal amount of the then outstanding Notes may petition at the expense of the Company any
court of competent jurisdiction for the appointment of a successor Trustee.

three months, fails to comply with Section 7.10, such Holder may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) 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
Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the
successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to
the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant
to this Section 7.08, the Company’s obligations under Section 7.07 hereof shall continue for the
benefit of the retiring Trustee.

 

94

 

Section 7.09. Successor Trustee by Merger, Etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of
its corporate trust business to, another Person, the successor Person without any further act shall
be the successor Trustee.

ARTICLE EIGHT

Defeasance and Covenant Defeasance

Section 8.01. Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may, at its option and at any time, elect to have either Section 8.02 or 8.03
hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in
this Article Eight.

Section 8.02. Legal Defeasance and Discharge.

Upon the Company’s exercise of the option applicable to this Section 8.02, the Company shall,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have
been discharged from its obligations with respect to all outstanding Notes and all obligations of
the Guarantors shall be deemed to have been discharged with respect to their obligations under the
Guarantees on the date the conditions set forth below are satisfied (hereinafter, “Legal
Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors
shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding
Notes and Guarantees, respectively, which shall thereafter be deemed to be “outstanding” only for
the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses
(a) and (b) below, and to have satisfied all of their other obligations under such Notes and this
Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following provisions which shall survive until
otherwise terminated or discharged hereunder:

(a) the rights of Holders of outstanding Notes to receive solely from Funds in Trust (as
defined in Section 8.04 hereof and as more fully set forth in such Section) payments in respect of
the principal of, premium, if any, and interest on such Notes when such payments are due, (b)
subject to the preceding clause (a), the Company’s obligations with respect to such Notes under
Article Two and Section 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (d) this Article Eight. Subject to compliance with this Article Eight, the
Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its
option under Section 8.03 hereof.

 

95

 

Section 8.03. Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section
8.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, be released from its obligations, and each Restricted Subsidiary shall be released from its
obligations, under the covenants contained in Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12,
4.13, 4.14, 4.15, 4.17, 4.19 and 5.01 hereof with respect to the outstanding Notes on and after the
date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant
Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of
any direction, waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all
other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for
accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Notes, the Company and each Restricted Subsidiary may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event of Default under
Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes
shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of
the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth
in Section 8.04 hereof, Sections 6.01(c) through (g) shall not constitute Events of Default.

Section 8.04. Conditions to Legal Defeasance or Covenant Defeasance.

The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof
to the outstanding Notes:

(a) the Company must irrevocably deposit or cause to be deposited with the Trustee, in trust
for the benefit of the Holders of the Notes cash in United States dollars, U.S. Government
Obligations, or a combination thereof (“Funds in Trust”), in such amounts as, in the
aggregate, will be sufficient, in the opinion of a nationally recognized firm of independent public
accountants or a nationally recognized investment banking firm, to pay and discharge the principal
of, premium, if any, and interest on the outstanding Notes on the Stated Maturity (or on any date
after May 1, 2010 (such date being referred to as the “Defeasance Redemption Date”), if at
or prior to electing either Legal Defeasance or Covenant Defeasance, the Company has
delivered to the Trustee an irrevocable notice to redeem all of the outstanding Notes on the
Defeasance Redemption Date);

 

96

 

(b) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an
opinion of independent counsel in the United States stating that (i) the Company has received from,
or there has been published by, the Internal Revenue Service a ruling or (ii) since the date of
this Indenture, there has been a change in the applicable federal income tax law, in either case to
the effect that, and based thereon such opinion of independent counsel in the United States shall
confirm that, the Holders and Beneficial Owners of the outstanding Notes will not recognize income,
gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred;

(c) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an
opinion of independent counsel in the United States to the effect that the Holders and Beneficial
Owners of the outstanding Notes will not recognize income, gain or loss for federal income tax

same amounts, in the same manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred;

(d) no Default or Event of Default shall have occurred and be continuing on the date of such
deposit or insofar as clause (h) or (i) of Section 6.01 is concerned, at any time during the period
ending on the 91st day after the date of deposit;

(e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of,
or constitute a Default under, this Indenture or any other material agreement or instrument to
which the Company, any Guarantor or any Restricted Subsidiary is a party or by which it is bound;

(f) such Legal Defeasance or Covenant Defeasance shall not result in the trust arising from
such deposit constituting an investment company within the meaning of the Investment Company Act of
1940, as amended, unless such trust shall be registered under such Act or exempt from registration
thereunder;

(g) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the
deposit was not made by the Company with the intent of preferring the Holders of the Notes or any
Guarantee over the other creditors of the Company or any Guarantor with the intent of defeating,
hindering, delaying or defrauding creditors of the Company, any Guarantor or others;

(h) no event or condition shall exist that would prevent the Company from making payments of
the principal of, premium, if any, and interest on the Notes on the date of such deposit or at any
time ending on the 91st day after the date of such deposit; and

(i) the Company will have delivered to the Trustee an Officers’ Certificate and an opinion of

Section 8.05. Deposited Money and U.S. Government Obligations to Be Held in Trust; Other
Miscellaneous Provisions.

(a) Subject to Section 8.06 hereof, all money and non-callable U.S. Government Obligations
(including the proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04
hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due thereon in respect of
principal, premium and interest, but such money need not be segregated from other funds except to
the extent required by law.

(b) The Company shall pay and indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against the cash or non-callable U.S. Government Obligations deposited
pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other
than any such tax, fee or other charge which by law is for the account of the Holders of the
outstanding Notes.

(c) Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver
or pay to the Company from time to time upon the request of the Company any money or non-callable
U.S. Government Obligations held by it as provided in Section 8.04 hereof which, in the opinion of
a nationally recognized firm of independent public accountants, investment bank, or appraisal firm
expressed in a written certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06. Repayment to the Company.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of, premium, if any, or interest on any Note and remaining
unclaimed for two years after such principal, and premium, if any, or interest has become due and
payable shall be paid to the Company upon its request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter look only to the Company
for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such
trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make any such repayment,
shall at the expense of the Company cause to be published once, in The New York Times and
The Wall Street Journal (national edition), notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining shall be repaid to
the Company.

 

98

 

Section 8.07. Reinstatement.

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable
U.S. Government Obligations in accordance with Section 8.02 or 8.03 hereof, as the case may be, by
reason of any order or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, then the Company’s obligations to make the related payments
under this Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may
be; provided, however, that, if the Company make any payment of principal of, premium, if any, or
interest on any Note following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment from the money held
by the Trustee or Paying Agent.

Section 9.02. With Consent of Holders of Notes.

(a) Except as provided below in this Section 9.02, the Company, any Guarantor, any other
obligor under the Notes and the Trustee may amend or supplement this Indenture or the Notes with

this Indenture;

(iv) modify any of the provisions relating to supplemental indentures requiring the
consent of Holders or relating to the waiver of past defaults or relating to the waiver of
certain covenants, except to increase the percentage of such outstanding Notes required for
such actions or to provide that certain other provisions of this Indenture cannot be

(b) The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Persons entitled to consent to any amendment, waiver or supplement hereto. If a

such Holders remain Holders after such record date; provided that unless such consent shall have
become effective by virtue of the requisite percentage having been obtained prior to the date which
is 90 days after such record date, any such consent previously given shall automatically and
without further action by any Holder be canceled and of no further effect.

 

101

 

(c) Upon the request of the Company accompanied by a resolution of its Board of Directors
authorizing the execution of any such amendment, waiver or supplement, and upon the filing with the
Trustee of evidence reasonably satisfactory to the Trustee of the consent of the Holders of Notes
as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 and
Section 12.04 hereof, the Trustee shall join with the Company in the execution of such amendment,

its discretion, but shall not be obligated to, enter into such amendment, waiver or supplement.

(d) It shall not be necessary for the consent of the Holders of Notes under this Section 9.02
to approve the particular form of any proposed amendment, waiver or supplement, but it shall be
sufficient if such consent approves the substance thereof.

(e) After an amendment, waiver or supplement under this Section 9.02 becomes effective, the
Company shall mail to the Holders of Notes affected thereby a notice briefly describing the
amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a
Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or
portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of
the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written notice of revocation

this Article Nine if the amendment or supplement does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. Neither the Company nor any Guarantor may sign an
amendment or supplemental indenture or Note or Guarantee until its Board of Directors or trustees
or sole member (or committee or Person serving a similar function), as the case may be, approves
it. In executing any amended or supplemental indenture or Note, the Trustee shall be entitled to
receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon an Officers’
Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental
indenture is authorized or permitted by this Indenture.

ARTICLE TEN

Guarantees

(a) Subject to this Article Ten, each of the Guarantors hereby, jointly and severally, fully
and unconditionally, guarantees, on a senior unsecured basis, to each Holder of a Note
authenticated and delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of
the Company hereunder or thereunder, that: (i) the principal of, premium, if any, and interest on
the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption
or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful

performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension
of time of payment or renewal of any Notes or any of such other obligations, that same will be
promptly paid in full when due or performed in accordance with the terms of the extension or
renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any
amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be
jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that, to the maximum extent permitted under applicable law,
their obligations hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the
recovery of any judgment against the Company, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or defense of a
Guarantor. Subject to Section 6.06 hereof, each Guarantor hereby waives diligence, presentment,
demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, protest, notice and all
demands whatsoever and covenant that this Guarantee shall not be discharged except by complete
performance of the obligations contained in the Notes and this Indenture.

 

103

 

(c) If any Holder or the Trustee is required by any court or otherwise to return to the
Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in
relation to either of the Company or the Guarantors, any amount paid by either to the Trustee or
such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect.

(d) Each Guarantor agrees that it shall not be entitled to any right of subrogation in
relation to the Holders in respect of any obligations guaranteed hereby until payment in full of
all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors,
on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Six hereof for the purposes
of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (ii) in the event of any
declaration of acceleration of such obligations as provided in Article Six hereof, such obligations
(whether or not due and payable) shall forthwith become due and payable by the Guarantors for the
purpose of this Guarantee. Each Guarantor that makes a payment or distribution under its Guarantee
shall have the right to seek contribution from any non-paying Guarantor, in a pro rata amount based
on the net assets of each Guarantor determined in accordance with GAAP, so long as the exercise of
such right does not impair the rights of the Holders under the Guarantee.

(e) The Obligations of each Guarantor under its Guarantee pursuant to this Article Ten shall
rank equally in right of payment with other existing and future senior Indebtedness of such
Guarantor, and senior in right of payment to all existing and future Subordinated Indebtedness of
such Guarantor.

Section 10.02. Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the
intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent
transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any
Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors
hereby irrevocably agree that the obligations of such Guarantor are limited to the maximum amount
which, after giving effect to all other contingent and fixed liabilities of such Guarantor, and
after giving effect to any collections from or payments made by or on behalf of any other Guarantor
in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its
contribution obligations under this Article Ten, will result in the obligations of such Guarantor
under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal
or state law. Until such time as the Notes are paid in full, each Guarantor hereby waives all
rights of subrogation or contribution, whether arising by contract or operation of law (including,
without limitation, any such right arising under federal Bankruptcy Law) or otherwise by reason of
any payment by it pursuant to the provisions of this Article Ten.

 

104

 

Section 10.03. Execution and Delivery of Guarantee.

(a) To evidence its Guarantee set forth in Section 10.01, on the Issue Date each Initial
Guarantor shall be required to have a notation of such Guarantee substantially in the form
included in Exhibit E hereto endorsed by an Officer of such Initial Guarantor by
manual or facsimile signature on each Note authenticated and delivered by the Trustee.

(b) Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01 shall remain in
full force and effect notwithstanding any failure to endorse on each Note a notation of such
Guarantee.

(c) If an Officer whose signature is on this Indenture or on the Guarantee no longer holds
that office at the time the Trustee authenticates the Note on which a Guarantee is endorsed, the
Guarantee shall be valid nevertheless.

(d) The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors.

(e) Subsequent to the date of this Indenture, in the event a Restricted Subsidiary is required
by Section 4.12 hereof to guarantee the Company’s obligations under the Notes and this Indenture,
the Company shall cause such Restricted Subsidiary to execute a supplemental indenture to this
Indenture substantially in the form included in Exhibit F hereto in accordance with Section
4.12 hereof and this Article Ten, to the extent applicable.

Section 10.04. Releases of Guarantors.

(a) A Guarantor will be deemed automatically and unconditionally released and discharged from
all of its obligations under its Guarantee without any further action on the part of the Trustee or
any Holder of the Notes:

(i) in connection with any sale or other disposition of all or substantially all of the
assets of that Guarantor (including by way of merger or consolidation) to one or more
Persons that are not (either before or after giving effect to such transaction) the Company
or a Restricted Subsidiary, if the sale or other disposition of all or substantially all of
the assets of that Guarantor complies with Sections 4.11 and 4.09 hereof;

(ii) in connection with any sale of all of the Capital Stock of a Guarantor to one or
more Persons that are not (either before or after giving effect to such transaction) the
Company or a Restricted Subsidiary, if the sale of all such Capital Stock of that Guarantor
complies with Sections 4.11 and 4.09 hereof;

(iii) if the Company properly designates such Guarantor as a Non-Guarantor Restricted
Subsidiary and such Restricted Subsidiary is not required to issue a Guarantee of the Notes
pursuant to Section 4.12 hereof;

(iv) if the Company properly designates any Restricted Subsidiary that is a Guarantor
as an Unrestricted Subsidiary;

(v) if a Guarantor under any Credit Facility is released from its guarantee issued
pursuant to the terms of any Credit Facility of the Company or any direct or
indirect Restricted Subsidiary, and such Guarantor is not an obligor under any
Indebtedness other than the Notes; or

 

105

 

(vi) if the Notes are discharged in accordance with the procedures set forth in Article
Eight or Article Eleven hereof;

provided that any such release and discharge pursuant to clauses (i), (ii), (iii), (iv) and (v)
above shall occur only to the extent that all obligations of such Guarantor under all of its
guarantees of, and under all of its pledges of assets or other security interests which secure any,
Indebtedness of the Company shall also terminate at such time. At the request of the Company, and
upon delivery to the Trustee of an Officers’ Certificate and an Opinion of Counsel that such
release complies with this Indenture, the Trustee shall execute and deliver an appropriate
instrument evidencing such release.

(b) Any Guarantor not released from its obligations under its Guarantee shall remain liable
for the full amount of principal of and interest on the Notes and for the other obligations of any
Guarantor under this Indenture as provided in this Article Ten.

ARTICLE ELEVEN

Satisfaction and Discharge

Section 11.01. Satisfaction and Discharge.

This Indenture will be discharged and will cease to be of further effect (except as to
surviving rights of registration of transfer or exchange of the Notes as expressly provided for in
this Indenture) as to all outstanding Notes under this Indenture when:

(a) either:

(i) all such Notes theretofore authenticated and delivered (except lost, stolen or
destroyed Notes which have been replaced or paid or Notes whose payment has been deposited
in trust or segregated and held in trust by the Company and thereafter repaid to the Company
or discharged from such trust as provided for in this Indenture) have been delivered to the
Trustee for cancellation, or

(ii) all Notes not theretofore delivered to the Trustee for cancellation (A) have
become due and payable, (B) will become due and payable at their Stated Maturity within one
year, or (C) are to be called for redemption within one year under arrangements satisfactory
to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the
expense, of the Company;

(b) the Company or any Guarantor has irrevocably deposited or caused to be deposited with the
Trustee as trust funds in trust an amount in United States dollars, U.S. Government Obligations, or
a combination thereof, sufficient to pay and discharge the entire Indebtedness on the Notes not
theretofore delivered to the Trustee for cancellation, including principal of, premium, if any, and
accrued interest at such Maturity, Stated Maturity or redemption date;

 

106

 

(c) no Default or Event of Default shall have occurred and be continuing on the date of such
deposit;

(d) the Company or any Guarantor has paid or caused to be paid all other sums payable under
this Indenture by the Company and any Guarantor;

(e) the Company has delivered to the Trustee an Officers’ Certificate and an opinion of
independent counsel each stating that (i) all conditions precedent under this Indenture relating to
the satisfaction and discharge of this Indenture have been complied with and (ii) such satisfaction
and discharge will not result in a breach or violation of, or constitute a default under, this
Indenture or any other material agreement or instrument to which the Company, any Guarantor or any
Subsidiary is a party or by which the Company, any Guarantor or any Subsidiary is bound; and

(f) the Company has delivered irrevocable instructions to the Trustee hereunder to apply any
deposited money described in clause (b) above to the payment of the Notes at Maturity, Stated
Maturity or the redemption date, as the case may be.

Section 11.02. Deposited Money and U.S. Government Obligations to Be Held in Trust; Other
Miscellaneous Provisions.

(a) Subject to Section 11.03 hereof, all money and non-callable U.S. Government Obligations
(including the proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 11.02, the “Trustee”) pursuant to Section 11.01 hereof in
respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance
with the provisions of such Notes and this Indenture, to the payment, either directly or through
any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to
the Holders of such Notes of all sums due and to become due thereon in respect of principal,
premium and interest, but such money need not be segregated from other funds except to the extent
required by law.

(b) Notwithstanding the above, the Trustee shall pay to the Company from time to time upon its
request any cash or U.S. Government Obligations held by it as provided in this Section 11.02 which,
in the opinion of a nationally recognized firm of independent public accountants expressed in a
written certification delivered to the Trustee, are in excess of the amount thereof that would then
be required to be deposited to effect a satisfaction and discharge under this Article Eleven.

Section 11.03. Repayment to the Company.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of, premium or interest on any Note and remaining unclaimed
for two years after such principal, and premium, if any, or interest has become due and payable
shall be paid to the Company on its request or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Note shall thereafter look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that
the Trustee or such Paying Agent, before being
required to make any such repayment, shall at the expense of the Company cause to be published
once, in The New York Times or The Wall Street Journal (national edition), notice
that such money remains unclaimed and that, after a date specified therein, which shall not be less
than 30 days from the date of such notification or publication, any unclaimed balance of such money
then remaining shall be repaid to the Company.

or 10.04.

Section 12.11. Severability.

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

Section 12.12. Counterpart Originals.

The parties may sign any number of copies of this Indenture. Each signed copy shall be an
original, but all of them together represent the same agreement.

Section 12.13. Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by the Holders may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such Holders in person or by
agents duly appointed in writing, and may be given or obtained in connection with a purchase of, or
tender offer or exchange offer for, outstanding Notes; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to
the Trustee and, where it is hereby expressly required, to the Company. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred
to as the “Act” of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and conclusive in favor of the Trustee and the Company if made in the
manner provided in this Section 12.13.

(b) The fact and date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a notary public or
other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to such witness, notary or officer the execution
thereof. Where such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof of authority. The
fact and date of the execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(c) Notwithstanding anything to the contrary contained in this Section 12.13, the principal
amount and serial numbers of Notes held by any Holder, and the date of holding the same, shall be
proved by the register of the Notes maintained by the Registrar as provided in Section 2.04 hereof.

 

111

 

(d) If the Company shall solicit from the Holders of the Notes any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may, at their option,
by or pursuant to a resolution of its Board of Directors, fix in advance a record date for the
determination of Holders entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding
TIA Section 316(c), such record date shall be the record date specified in or pursuant to such
Board Resolution, which shall be a date not earlier than the date 30 days prior to the first
solicitation of Holders generally in connection therewith or the date of the most recent list of
Holders forwarded to the Trustee prior to such solicitation pursuant to Section 2.06 hereof and not
later than the date such solicitation is completed. If such a record date is fixed, such request,
demand, authorization, direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of record at the close of business on such record date shall
be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion
of the then outstanding Notes have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that purpose the then
outstanding Notes shall be computed as of such record date; provided that no such authorization,
agreement or consent by the Holders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than eleven months after
the record date.

(e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the
Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note
issued upon the registration or transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance
thereon, whether or not notation of such action is made upon such Note.

(f) Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder
with regard to any particular Note may do so itself with regard to all or any part of the principal
amount of such Note or by one or more duly appointed agents each of which may do so pursuant to
such appointment with regard to all or any part of such principal amount.

(g) For purposes of this Indenture, any action by the Holders which may be taken in writing
may be taken by electronic means or as otherwise reasonably acceptable to the Trustee.

Section 12.14. Benefit of Indenture.

Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other
than the parties hereto, any Paying Agent, any Registrar and its successors hereunder, and the
Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 12.15. Table of Contents, Headings, Etc.

The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this
Indenture have been inserted for convenience of reference only, are not to be considered a part of
this Indenture and shall in no way modify or restrict any of the terms or provisions hereof.

BRIGHAM EXPLORATION COMPANY

8.750% Senior Notes due 2018

Capitalized terms used herein shall have the meanings assigned to them in the Indenture
referred to below unless otherwise indicated.

1. Interest. The Company promises to pay interest on the principal amount of this Note
at 8.750% per annum from the date hereof until maturity [and shall pay Additional Interest, if any,
as provided in the Registration Rights Agreement, dated September 27, 2010† referred
below]*. The Company shall pay interest [and Additional Interest, if any,]*
semi-annually in arrears on April 1 and October 1 of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each an “Interest Payment Date”).
Interest on the Notes shall accrue from the most recent date to which interest has been paid on the
Notes (or one or more Predecessor Notes) or, if no interest has been paid, from the date of
original issuance; provided that if there is no existing Default in the payment of interest, and if
this Note is authenticated between a record date referred to on the face hereof and the next
succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment
Date; provided further that the first Interest Payment Date shall be [April 1, 2011]‡.
The Company shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate
that is 1% per annum in excess of the rate then in effect; it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest [and Additional Interest]* (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful. Interest shall be computed on the basis of a
360-day year of twelve 30-day months. If a payment date is not a Business Day, payment may be made
on the next succeeding day that is a Business Day, and no interest shall accrue on such payment for
the intervening period.

[This Exchange Note was issued in connection with the Exchange Offer pursuant to which the
8.750% Senior Notes due 2018 in like principal amount were exchanged for Exchange Notes. The
Exchange Notes rank pari passu in right of payment with the Initial Notes. For any period in which
the Initial Note exchanged for this Exchange Note was outstanding, Additional Interest may be due
and owing on the Initial Note in connection with the Registration Rights Agreement.]**

the Indenture, shall act as Paying Agent and Registrar. The Company may change any Paying Agent or
Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such

Indenture by reference to the Trust Indenture Act of 1939, as amended. The Notes are subject to all
such terms, and Holders are referred to the Indenture and such Act for a statement of such terms.
To the extent any provision of this Note conflicts with the express provisions of the Indenture,

this Note is issued provides that an unlimited amount of Additional Notes may be issued thereunder,
subject to compliance with the covenants therein.

(b) In addition, at any time and from time to time prior to October 1, 2013, the Company may
use the net proceeds of one or more Equity Offerings to redeem up to an aggregate of 35% of the
aggregate principal amount of Notes issued under the Indenture (including the principal amount of
any Additional Notes issued under the Indenture) at a redemption price equal to 108.750% of the
aggregate principal amount of the Notes redeemed,
plus accrued and unpaid interest, if any, to the redemption date (subject to the rights of
holders of record on relevant record dates to receive interest due on an interest payment date). At
least 65% of the aggregate principal amount of Notes (including the principal amount of any
Additional Notes issued under the Indenture) must remain outstanding immediately after the
occurrence of such redemption. In order to effect this redemption, the Company must complete such
redemption no later than 180 days after the closing of the related Equity Offering.

in excess thereof, at a purchase price in cash in an amount equal to 101% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the date of purchase, pursuant to a Change of
Control Offer in accordance with the procedures set forth in the Indenture.

(b) Under certain circumstances described in the Indenture, the Company will be required to
apply the proceeds of Asset Sales to the repayment of the Notes and/or Pari Passu Indebtedness.

8. Selection and Notice of Redemption. If less than all of the Notes are to be
redeemed or purchased in an offer to purchase at any time, the Trustee shall select the Notes to be
redeemed or purchased among the Holders of the Notes not more than 60 days prior to the redemption
date in compliance with the requirements of the principal national securities exchange, if any, on
which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or in
accordance with any other method the Trustee considers fair and reasonable. Redemptions pursuant to
Section 3.07(b) of the Indenture shall be made on a pro rata basis or on as nearly a pro rata basis
as practicable (subject to the provisions of the Depositary). In the event of partial redemption by
lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not
less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding
Notes not previously called for redemption. Notices of redemption may not be conditional. If any
Note is to be redeemed in part only, the notice of redemption that relates to that Note will state
the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to
the unredeemed portion of the original Note will be issued in the name of the Holder thereof upon
cancellation of the original Note. Notes
called for redemption become due on the date fixed for redemption. On and after the redemption

transfer documents and the Company may require a Holder to pay any taxes and fees required by law
or permitted by the Indenture. The Company is not required to transfer or exchange any Note
selected for redemption. Also, the Company is not required to transfer or exchange any Note for a
period of 15 days before a selection of Notes to be redeemed.

10. Persons Deemed Owners. The registered Holder of a Note will be treated as its
owner for all purposes.

11. Amendment, Supplement and Waiver. The Indenture or the Notes may be amended or
supplemented only as provided in the Indenture.

12. Defaults. In the case of an Event of Default arising from certain events of
bankruptcy, insolvency or reorganization specified in the Indenture, with respect to the Company or
any Significant Subsidiary, all outstanding Notes will become due and payable immediately without
further action or notice. If any other Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the then outstanding Notes may declare all
unpaid principal of, premium, if any, and accrued interest on all Notes to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders of
the Notes) and upon any such declaration, such principal, premium, if any, and interest shall
become due and payable immediately. The Trustee may withhold from Holders of the Notes notice of
any continuing Default or Event of Default (except a Default or Event of Default relating to the
payment of principal or interest) if it determines that withholding notice is in their interest.
The Holders of not less than a majority in aggregate principal amount of the Notes outstanding by
notice to the Trustee may on behalf of the Holders of all outstanding Notes waive any past Default
and its consequences under the Indenture except a Default (1) in the payment of the principal of,
premium, if any, or interest on any Note (which may only be waived with the consent of each Holder

amendment.

capacity, may make loans to, accept deposits from, and perform services for the Company or its
Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the
Trustee.

14. No Recourse Against Others. No director, officer, employee, member, limited
partner or stockholder of the Company or any Restricted Subsidiary, as such, will have any
liability for any obligations of the Company or the Restricted Subsidiaries under the Notes, the
Indenture or the Guarantees to which they are a party, or for any claim based on, in respect of, or
by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note
waives and releases all such liability. The waiver and release are part of the consideration for
issuance of the Notes. The waiver may not be effective to waive liabilities under the federal
securities laws.

15. Authentication. This Note shall not be valid until authenticated by the manual
signature of the Trustee or an authenticating agent.

Company, the Guarantors and the parties named on the signature pages thereof.]*

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

the laws of the State of New York, without giving effect to the conflicts of laws principles
thereof.
