     THIS THIRD SUPPLEMENTAL INDENTURE, dated as of April 3, 2006 (this “Third Supplemental
Indenture”), supplements and amends the Subordinated Indenture dated as of December 10, 2001 (the
“Original Indenture”) between NEWFIELD EXPLORATION COMPANY, a Delaware corporation, as issuer (the
“Company”), and WACHOVIA BANK, NATIONAL ASSOCIATION, a national banking association (f/k/a First
Union National Bank), as trustee (the “Trustee”).

RECITATIONS OF THE COMPANY

     WHEREAS, the Company and the Trustee have heretofore executed and delivered the Original
Indenture to provide for the issuance of its subordinated debt securities to be issued in one or
more series;

     WHEREAS, Section 9.01 of the Original Indenture provides, among other things, that the Company
and the Trustee may without the consent of Holders enter into Indentures supplemental to the
Original Indenture to, among other things, (a) add to, change or eliminate any of the provisions of
the Original Indenture in respect of one or more series of Securities; provided, however, that any
such addition, change or elimination shall (i) neither (A) apply to any Security of any series
created prior to the execution of such supplemental indenture and entitled to the benefit of such
provision nor (B) modify the rights of the Holder of any such previously issued Security with
respect to such provision or (ii) shall become effective only when there is no such Security
Outstanding and (b) establish the form or terms of Securities of any series as permitted by
Sections 201 and 301;

     WHEREAS, the Company desires to provide for the issuance of a new series of Securities to be
designated as the “65⁄8% Senior Subordinated Notes due 2016” (the “65⁄8% Notes”), and to set forth the
terms that will be applicable thereto;

     WHEREAS, all action on the part of the Company necessary to authorize the issuance of the 65⁄8%
Notes under the Original Indenture and this Third Supplemental Indenture (the Original Indenture,
as amended and supplemented by this Third Supplemental Indenture, being hereinafter called the
“Indenture”) has been duly taken; and

     WHEREAS, all acts and things necessary to make the 65⁄8% Notes, when executed by the Company and
authenticated and delivered by the Trustee as provided in the Original Indenture, the legal, valid
and binding obligations of the Company, and to constitute these presents a valid and binding
supplemental indenture according to its terms binding on the Company, have been done and performed,
and the execution of this Third Supplemental Indenture and the creation and issuance under the
Indenture of the 65⁄8% Notes have in all respects been duly authorized, and the Company in the
exercise of the legal right and power vested in it, executes this Third Supplemental Indenture and
proposes to create, execute, issue and deliver the 65⁄8% Notes.

NOW, THEREFORE, THIS THIRD SUPPLEMENTAL INDENTURE WITNESSETH:

     That, in order to establish the designation, form, terms and provisions of, and to authorize
the authentication and delivery of the 65⁄8% Notes, and in consideration of the acceptance of the 65⁄8%
Notes by the Holders thereof and of other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1

 

     SECTION 1.       Creation of 65⁄8% Notes.

     (a)       Pursuant to Sections 201 and 301 of the Original Indenture, there is hereby created a new
series of Securities designated as the “65⁄8% Senior Subordinated Notes due 2016” (which are
hereinafter referred to as the “65⁄8% Notes” for purposes of this Third Supplemental Indenture). The
Trustee shall authenticate 65⁄8% Notes for original issue on the Issue Date in the aggregate
principal amount of $550,000,000 (the “Original 65⁄8% Notes”) upon a Company Order for the
authentication and delivery of Notes, without any further action by the Company. The Original 65⁄8%
Notes shall be issued initially in the form of one or more Global Securities substantially in the
form set forth on Exhibit A to the Third Supplemental Indenture, shall have the terms set forth
therein and shall be entitled to the benefits of the other provisions of the Original Indenture as
modified by this Third Supplemental Indenture and specified herein. The terms of the 65⁄8% Notes set
forth on Exhibit A hereto are incorporated by reference herein as if set forth herein in their
entirety. The
65/8% Notes
Shall be defeasible pursuant to both Sections 1302 and 1303.

     (b)       Subject to its compliance with Section 1010 of the Indenture, if then applicable, with
respect to any 65⁄8% Notes issued after the Issue Date (except for 65⁄8% Notes authenticated and
delivered upon registration of transfer of, or in exchange for, or in lieu of, other 65⁄8% Notes
pursuant to Section 304, 305, 306, 906 or 1107) (the “Additional 65⁄8% Notes”), there shall be
established in or pursuant to a resolution of the Board of Directors of the Company:

     (1)       that such Additional 65⁄8% Notes shall be issued as part of the same or a different
series as the Original 65⁄8% Notes;

     (2)       the aggregate principal amount of such Additional 65⁄8% Notes which may be
authenticated and delivered under the Indenture, which may be in an unlimited aggregate
principal amount or which may be in a limited principal amount (except for Additional 65⁄8%
Notes authenticated and delivered upon registration of transfer of, or in exchange for, or
in lieu of, other 65⁄8% Notes pursuant to Section 304, 305, 306, 906 or 1107 and except for
Additional 65⁄8% Notes which, pursuant to Section 303, are deemed never to have been
authenticated and delivered hereunder);

     (3)       the issue price and issuance date of such Additional 65⁄8% Notes, including the
date from which interest on such Additional 65⁄8% Notes shall accrue; provided, however,
that no Additional 65⁄8% Notes may be issued at a price that would cause such Additional 65⁄8%
Notes to have “original issue discount” within the meaning of the Code;

     (4)       if applicable, that such Additional 65⁄8% Notes shall be issuable in whole or in
part in the form of one or more Global Securities and, in such case, the respective
Depositaries for such Global Securities, the form of any legend or legends that shall be
borne by any such Global Security in addition to or in lieu of that set forth in
Exhibit A and any circumstances in addition to or in lieu of those set forth in the
Indenture in

2

 

which any such Global Security may be exchanged in whole or in part for 65⁄8%
Notes registered, and any transfer of such Global Security in whole or in part may be
registered, in the name or names of Persons other than the Depositary for such Global
Security or a nominee thereof; and

     (5)       if applicable, that such Additional 65⁄8% Notes shall not be registered under the
Securities Act, but shall be issued pursuant to an exemption from registration under the
Securities Act, shall bear additional appropriate legends and shall have the benefit of
registration rights.

Except as set forth above, such Additional 65⁄8% Notes shall have the terms set forth in Exhibit A to
this Third Supplemental Indenture, such Additional 65⁄8% Notes shall be entitled to the benefits of
the other provisions of the Original Indenture as modified by this Third Supplemental Indenture,
and the Original 65⁄8% Notes and such Additional 65⁄8% Notes shall be treated as a single class for all
purposes under the Indenture, including, without limitation, waivers, amendments, redemptions and
offers to purchase.

     SECTION 2.       Definitions.

     (a)       Capitalized terms used herein and not otherwise defined shall have the respective meanings
assigned thereto in the Original Indenture.

     (b)       Section 101 of the Original Indenture is amended and supplemented by inserting or

any state or federal income taxes, as estimated by the Company’s reserve engineers in a
reserve report prepared as of the end of the fiscal year ending at least 45 days prior to
the date of determination, as increased by, as of the date of determination, the discounted
future net revenue calculated in accordance with SEC guidelines (utilizing the prices

Restricted Subsidiaries attributable to acquisitions consummated since the date of
such reserve report, and

exploitation, production or other activities which reserves were not reflected in

calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end
reserve report) attributable to:

     (C)       estimated proved crude oil and natural gas reserves of the Company and its
Restricted Subsidiaries reflected in such reserve report produced or disposed of
since the date of such reserve report, and

     (D)       reductions in the estimated crude oil and natural gas reserves of the
Company and its Restricted Subsidiaries reflected in such reserve report since the
date of such reserve report attributable to downward determinations of estimates of

exploitation, production or other activities conducted or otherwise occurring since
the date of such reserve report which would, in accordance with standard industry
practice, result in such determinations;

     (2)       the capitalized costs that are attributable to crude oil and natural gas properties

independent appraisers, of other tangible assets of the Company and its Restricted
Subsidiaries as of a date no earlier than the most recent fiscal year for which financial
statements of the Company have been made publicly available prior to the date of

of such assets if no such appraisal has been performed); minus

     (b)       to the extent not otherwise taken into account in the immediately preceding clause (a),

(utilizing the same prices utilized in the Company’s year-end reserve report), attributable
to reserves subject to participation interests, overriding royalty interests or other
interests of third parties, pursuant to participation, partnership, vendor financing or
other agreements then in effect, or which otherwise are required to be delivered to third
parties;

     (4)       the discounted future net revenue calculated in accordance with SEC guidelines
(utilizing the same prices utilized in the Company’s year-end reserve report), attributable

Production Payments on the schedules specified with respect thereto; and

attributable to reserves subject to Dollar-Denominated Production Payments that, based on
the estimates of production included in determining the discounted future net revenue
specified in the immediately preceding clause (a)(1) (utilizing the same prices utilized in
the Company’s year-end reserve report), would be necessary to satisfy fully the obligations
of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production
Payments on the schedules specified with respect thereto.

If the Company changes its method of accounting from the full cost method to the successful efforts
method or a similar method of accounting, “ACNTA” will continue to be calculated as if the Company

Person who would be an Affiliate of any such beneficial owner pursuant to the first sentence of

     “Asset Disposition” means any sale, lease, issuance, transfer or other disposition (or series
of related sales, leases, transfers or dispositions) by the Company or any Restricted Subsidiary,

to for the purposes of this definition as a “disposition”), of:

     (1)       any shares of Capital Stock of a Restricted Subsidiary (other than directors’
qualifying shares or shares required by applicable law to be held by a Person other than the
Company or a Restricted Subsidiary);

     (2)       all or substantially all the assets of any division or line of business of the

that the value of the property received by the Company or any Restricted Subsidiary
in such trade or exchange (including any cash or cash equivalents) is at least equal
to the fair market value (as determined in good faith by the Board of Directors, an
Officer or an officer of such Restricted Subsidiary with responsibility for such
transaction, which determination shall be conclusive evidence of compliance with
this provision) of the property (including any cash or cash equivalents) so traded
or exchanged;

     (D)       the creation of a Lien;

     (E)       a disposition of oil and natural gas properties in connection with tax

Subsidiary;

     (G)       surrender or waiver of contract rights or the settlement, release or

compounded semiannually) of the total obligations of the lessee for rental payments during the
remaining term of the lease included in such Sale/Leaseback Transaction (including any period for
which such lease has been extended); provided, however, that if such Sale/Leaseback Transaction
results in a Capital Lease Obligation, the amount of Indebtedness represented thereby will be
determined in accordance with the definition of “Capital Lease Obligation”.

     “Average Life” means, as of the date of determination, with respect to any Indebtedness, the
quotient obtained by dividing:

     (1)       the sum of the products of the numbers of years from the date of determination to
the dates of each successive scheduled principal payment of or redemption or similar
payment with respect to such Indebtedness multiplied by the amount of such payment by

7

     “Bank Indebtedness” means all Obligations pursuant to any Credit Facilities.

     “Board of Directors” means the board of directors of the Company or any committee thereof duly
authorized to act on behalf of such board.

     “Capital Lease Obligation” means an obligation that is required to be classified and accounted

Indebtedness represented by such obligation shall be the capitalized amount of such obligation
determined in accordance with GAAP; and the Stated Maturity thereof shall be the date of the last
payment of rent or any other amount due under such lease prior to the first date upon which such
lease may be terminated by the lessee without payment of a penalty.

     “Capital Stock” of any Person means any and all shares, units of beneficial interests, rights

     (1)       any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act)
is or becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange
Act, except that for purposes of this clause (1) such person shall be deemed to have
“beneficial ownership” of all shares that any such person has the right to acquire, whether
such right is exercisable immediately or only after the passage of time), directly or
indirectly, of more than 50% of the total voting power of the Voting Stock of the Company;

     (2)       during any period of two consecutive years, individuals who, at the beginning of
such period, constituted the Board of Directors (together with any new directors whose
election by such Board of Directors or whose nomination for election by the shareholders of
the Company was approved by a vote of the majority of the directors of the Company then
still in office who were either directors at the beginning of such period or whose election
or nomination for election was previously so approved) cease for any reason to constitute a
majority of the Board of Directors then in office;

     (3)       the adoption of a plan relating to the liquidation or dissolution of the Company;
or

     (4)       the merger or consolidation of the Company with or into another Person or the
merger of another Person with or into the Company, or the sale of all or substantially all
the assets of the Company (determined on a consolidated basis) to another Person, other than
a transaction following which (A) in the case of a merger or consolidation transaction,
holders of securities that represented 100% of the Voting Stock of the Company immediately
prior to such transaction (or other securities into which such securities are converted as
part of such merger or consolidation transaction) own directly or indirectly at least a
majority of the voting power of the Voting Stock of the surviving

8

 

Person in such merger or consolidation transaction immediately after such transaction
and (B) in the case of a sale of assets transaction, each transferee becomes an obligor in
respect of the 65⁄8% Notes and a Subsidiary of the transferor of such assets.

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

     “Company” means the party named as such in this Indenture until a successor replaces it and,
thereafter, means the successor. For the purposes of any part of any provision contained herein
which is required by the TIA, and only for the purposes of such part, to the extent required by the
context or by the TIA, “Company” shall also include each other obligor on the indenture securities.

     “Consolidated Coverage Ratio” as of any date of determination means the ratio of (x) the
aggregate amount of EBITDA for the period of the most recent four consecutive fiscal quarters for
which financial information of the Company has been made publicly available prior to the date of
such determination to (y) Consolidated Interest Expense for such four fiscal quarters; provided,
however, that:

     (1)       if the Company or any Restricted Subsidiary has Incurred any Indebtedness since
the beginning of such period that remains outstanding or if the transaction giving rise to
the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, or
both, then EBITDA and Consolidated Interest Expense for such period shall be calculated
after giving effect on a pro forma basis to such Indebtedness and the use of proceeds
thereof as if such Indebtedness had been Incurred on the first day of such period and such
proceeds had been applied as of such date;

     (2)       if the Company or any Restricted Subsidiary has repaid, repurchased, defeased or
otherwise discharged any Indebtedness since the beginning of such period or if any
Indebtedness is to be repaid, repurchased, defeased or otherwise discharged on the date of
the transaction giving rise to the need to calculate the Consolidated Coverage Ratio, then
EBITDA and Consolidated Interest Expense for such period shall be calculated on a pro
forma basis as if such discharge had occurred on the first day of such period and as if
the Company or such Restricted Subsidiary had not earned the interest income actually
earned (if any) during such period in respect of cash or Temporary Cash Investments used
to repay, repurchase, defease or otherwise discharge such Indebtedness;

     (3)       if, since the beginning of such period, the Company or any Restricted Subsidiary
shall have made any Asset Disposition, then EBITDA for such period shall be reduced by an
amount equal to EBITDA (if positive) directly attributable to the assets which were the
subject of such Asset Disposition for such period, or increased by an amount equal to
EBITDA (if negative), directly attributable thereto for such period and Consolidated
Interest Expense for such period shall be reduced by an amount equal to the Consolidated
Interest Expense directly attributable to any Indebtedness of the Company or any
Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect
to the Company and its continuing Restricted Subsidiaries in connection with such Asset
Disposition for such period (or, if the Capital Stock of any

9

 

Restricted Subsidiary is sold, the Consolidated Interest Expense for such period
directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the
Company and its continuing Restricted Subsidiaries are no longer liable for such
Indebtedness after such sale);

     (4)       if, since the beginning of such period, the Company or any Restricted Subsidiary
(by merger or otherwise) shall have made an Investment in any Restricted Subsidiary (or
any Person which becomes a Restricted Subsidiary) or an acquisition of material assets,
including any acquisition of assets occurring in connection with a transaction requiring a
calculation to be made under the Indenture, which constitutes all or substantially all of
an operating unit of a business, then EBITDA and Consolidated Interest Expense for such
period shall be calculated after giving pro forma effect thereto (including the Incurrence
of any Indebtedness) as if such Investment or acquisition had occurred on the first day of
such period; and

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

     For purposes of this definition, whenever pro forma effect is to be given to an acquisition of
assets, the amount of income or earnings relating thereto and the amount of Consolidated Interest
Expense associated with any Indebtedness Incurred in connection therewith, the pro forma

Significant Subsidiary; or

     (7)       principal of or interest on any Indebtedness (other than Non-Recourse Purchase
Money Indebtedness) of the Company, any Subsidiary Guarantor or any Significant Subsidiary
is not paid within any applicable grace period after payment is due, or the principal
thereof is accelerated by the holders thereof because of a default, and the total
principal amount of such Indebtedness exceeds $10 million, provided, however, if any such
Indebtedness is repaid or any such acceleration rescinded, within a period of 10 days
beyond the applicable grace period or the occurrence of such acceleration, as the case may
be, such Event of Default and any consequential acceleration of the 65⁄8% Notes shall be
automatically rescinded, so long as such rescission does not conflict with any judgment or
decree; or

     (8)       any judgment or decree for the payment of money in excess of $10 million above
the coverage under applicable insurance policies and indemnities as to which the relevant
insurer or indemnitor has not disclaimed responsibility is entered against the Company,
any Subsidiary Guarantor or any Significant Subsidiary, remains outstanding for a period
of 60 consecutive days following the entry of such judgment or decree and is not
discharged, waived, stayed, satisfied or bonded; or

     (9)       a Subsidiary Guaranty ceases to be in full force and effect (other than in
accordance with the terms of such Subsidiary Guaranty) for five days after there has been
given, by registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the Outstanding 65⁄8%
Notes a written notice specifying such default and requiring it to be remedied and stating
that such notice is a “Notice of Default” hereunder; or any Subsidiary Guarantor denies or
disaffirms its obligations under its Subsidiary Guaranty other than in accordance with the
terms of such Subsidiary Guaranty.

     (b)       The first paragraph of Section 502 of the Original Indenture is amended in its entirety
with respect to the 65⁄8% Notes to read as follows:

Section 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in Section 501(5) or 501(6))
with respect to the 65⁄8% Notes occurs and is continuing, then in every such case the

33

 

Trustee or the Holders of not less than 25% in principal amount of the Outstanding 65⁄8% Notes
may declare the principal amount of all the 65⁄8% Notes, together with all accrued but unpaid
interest thereon, to be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by Holders), and upon any such declaration such principal amount, together
with all accrued but unpaid interest thereon, shall become immediately due and payable. If an
Event of Default specified in Section 501(5) or 501(6) with respect to the 65⁄8% Notes occurs, the
principal amount of all the 65⁄8% Notes, together with all accrued but unpaid interest thereon, shall
ipso facto, and without any declaration or other action on the part of the Trustee or any Holder,
become immediately due and payable.

     SECTION 5.       Amendments to Articles Eight and Nine of the Original Indenture.

     (a)       Section 801 of the Original Indenture is amended in its entirety with respect to the 65⁄8%
Notes to read as follows:

Section 801. Company and Subsidiary Guarantors May Consolidate, Etc., Only on Certain
Terms.

     (a)       The Company shall not consolidate with or merge into any other Person or permit any other
Person to consolidate with or merge into the Company or, in a single transaction or a series of
related transactions, directly or indirectly, transfer, convey, sell, lease or otherwise dispose of
all or substantially all of its assets, unless:

     (1)       if the Company does not survive or the Company transfers, conveys, sells, leases or
otherwise disposes of all or substantially all of its assets, the successor entity (for
purposes of this Article Eight, a “Successor Company”) shall be a corporation, partnership,
limited liability company, trust or other Person organized and validly existing under the
laws of the United States of America, any state thereof or the District of Columbia, and
shall expressly assume, by an indenture supplemental hereto, executed and delivered to the
Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal
of and any premium and interest on all the Securities and the performance or observance of
every covenant of this Indenture on the part of the Company to be performed or observed;

     (2)       immediately after giving pro forma effect to such transaction and treating any
Indebtedness that becomes an obligation of the Company or the Successor Company, as
applicable, or any Subsidiary as a result of such transaction as having been Incurred by it
at the time of such transaction, no Default shall have happened and be continuing;

     (3)       immediately after giving pro forma effect to such transaction, the Company or the
Successor Company, as applicable, would be able to Incur an additional $1.00 of Indebtedness
pursuant to Section 1010(a);

     (4)       the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that such consolidation, merger, transfer, conveyance, sale, lease or
other disposition and, if a supplemental indenture is required in connection with such
transaction, such supplemental indenture comply with this Article and that all

34

 

conditions precedent herein provided for relating to such transaction have been
complied with; and

     (5)       the Company has delivered to the Trustee an Opinion of Counsel to the effect that
the Holders will not recognize income, gain or loss for Federal income tax purposes as a
result of such transaction 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 transaction had
not occurred;

provided, however, that clause (3) will not be applicable (A) to the Company consolidating with,
merging into, conveying, transferring, leasing or otherwise disposing of all or part of its assets
to a Subsidiary Guarantor, (B) to the Company merging with an Affiliate of the Company solely for
the purpose and with the sole effect of reincorporating the Company in another jurisdiction within
the United States of America or (C) at any time when the Company and its Restricted Subsidiaries
are not subject to the Suspended Covenants. For purposes of this Section 801(a), the transfer,
conveyance, sale, lease or other disposition of all or substantially all of the assets of one or
more Subsidiaries of the Company, which assets, if held by the Company instead of such
Subsidiaries, would constitute all or substantially all of the assets of the Company on a
consolidated basis, shall be deemed to be the disposition of all or substantially all of the assets
of the Company.

     (b)       The Company shall not permit any Subsidiary Guarantor to consolidate with or merge with or
into any Person, except another Subsidiary Guarantor or the Company, unless:

     (1)       except in the case of a Subsidiary Guarantor whose Capital Stock has been disposed
of in its entirety to another Person (other than to the Company or an Affiliate of the
Company), including through a merger or consolidation, if in connection therewith the
Company complies with its obligations under Section 1014 in respect of such disposition, the
resulting or surviving Person (if not such Subsidiary Guarantor) shall be a Person organized
and existing under the laws of the jurisdiction under which such Subsidiary Guarantor was
organized or under the laws of the United States of America, or any State thereof or the
District of Columbia, and such Person shall expressly assume, by a Guaranty Agreement, all
the obligations of such Subsidiary Guarantor under its Subsidiary Guaranty;

     (2)       immediately after giving effect to such transaction on a pro forma basis (and
treating any Indebtedness which becomes an obligation of the resulting or surviving Person
as a result of such transaction as having been issued by such Person at the time of such
transaction), no Default shall have occurred and be continuing; and

     (3)       the Company delivers to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that such consolidation or merger and such Guaranty Agreement comply
with this Indenture.

     (b)
      Sections 901 and 902 of the Original Indenture are amended in their entirety with respect
to the 65⁄8% Notes to read as follows:

35

 

Section 901. Supplemental Indentures Without Consent of Holders.

the Trustee, at any time and from time to time, may enter into one or more indentures supplemental
hereto, in form satisfactory to the Trustee, for any of the following purposes:

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

     (2)       to add to the covenants of the Company or a Subsidiary Guarantor for the benefit of
the Holders of all or any series of Securities (and if such covenants are to be for the
benefit of less than all series of Securities, stating that such covenants are expressly
being included solely for the benefit of such series) or to surrender any right or power
herein conferred upon the Company or a Subsidiary Guarantor; or

     (3)       to comply with Article Eight; or

     (4)       to add to or change any of the provisions of this Indenture to such extent as shall
be necessary to permit or facilitate the issuance of Securities (other than the 65⁄8% Notes)
in bearer form, registrable or not registrable as to principal, and with or without interest
coupons, or to permit or facilitate the issuance of Securities in uncertificated form
(provided that any uncertificated 65⁄8% Notes are issued in registered form for purposes of
Section 163(f) of the Code, or in a manner such that the uncertificated 65⁄8% Notes are
described in Section 163(f)(2)(B) of the Code); or

     (5)       to add to, change or eliminate any of the provisions of this Indenture in respect
of one or more other series of Securities, provided that any such addition, change or
elimination (A) shall neither (i) apply to any 65⁄8% Note entitled to the benefit of such
provision nor (ii) modify the rights of the Holder of any 65⁄8% Note with respect to such
provision or (B) shall become effective only when there is no 65⁄8% Note Outstanding; or

     (6)       to secure the Securities or provide for the guarantee of the Company’s obligations
under this Indenture and with respect to the Securities by another Person; or

     (7)       to establish the form or terms of Securities of any series as permitted by Sections
201 and 301; or

     (8)       to evidence and provide for the acceptance of appointment hereunder by a successor
Trustee with respect to the Securities of one or more series and to add to or change any of
the provisions of this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee, pursuant to the
requirements of Section 611; or

     (9)       to make any other change or provisions with respect to matters or questions arising
under this Indenture, provided that such action pursuant to this clause (9) shall not
adversely affect the interests of the Noteholders in any material respect; provided further, however, that any change to conform this Indenture to the

36

 

Prospectus
shall not be deemed to adversely affect such interests in any material respect; or

     (10)       to make any change in Article Fourteen or Sixteen that would limit or terminate
the benefits available to any holder of Senior Indebtedness thereunder.

     An amendment under this Section 901 may not make any change that would adversely affect the
rights under Article Fourteen or Sixteen of any holder of Senior Indebtedness then outstanding
unless the holders of such Senior Indebtedness (or their Representatives) consent to such change or
unless the notes, debentures, bonds or other similar instruments evidencing such Senior
Indebtedness so permit.

Section 902. Supplemental Indentures With Consent of Holders.

     With the consent of the Holders of not less than a majority in principal amount of the
Outstanding Securities of each series affected by such supplemental indenture (including consents
obtained in connection with a tender or exchange offer for the 65⁄8% Notes), by Act of said Holders
delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and
the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of this Indenture
or of modifying in any manner the rights of the Holders of Securities of such series under this
Indenture; provided, however, that no such supplemental indenture shall, without the consent of the
Holder of each Outstanding 65⁄8% Note affected thereby:

     (1)       extend the Stated Maturity of the principal of, or any installment of principal of
or interest on, any 65⁄8% Note, or reduce the principal amount thereof or the rate of interest
thereon or any premium payable upon the redemption thereof, or change the coin or currency
in which the principal of any 65⁄8% Note or any premium or interest thereon is payable, or
change the time at which any 65⁄8% Note may be redeemed pursuant to Article Three, or impair
the right under Section 508 of any Noteholder to receive any payment on such Holder’s 65⁄8%
Notes on or after the due date thereof or to institute suit for the enforcement of any such
payment;

     (2)       reduce the percentage in principal amount of the Outstanding 65⁄8% Notes, the consent
of whose Holders is required for any such supplemental indenture, or the consent of whose
Holders is required for any waiver provided for in Section 513 of this Indenture;

     (3)       modify any of the provisions of this Section, Section 513 or Section 1008, except
to increase any such percentage or to provide that certain other provisions of this
Indenture cannot be modified or waived without the consent of the Holder of each Outstanding
Security affected thereby; provided, however, that this clause shall not be deemed to
require the consent of any Holder with respect to changes in the references to “the Trustee”
and concomitant changes in this Section and Section 1008, or the deletion of this proviso,
in accordance with the requirements of Sections 611 and 901(8);

37

 

     (4)       make any change in the ranking or priority of any 65⁄8% Note that would adversely
affect the Noteholders in any material respect; or

     (5)       make any change in any Subsidiary Guaranty that would adversely affect the
Noteholders in any material respect.

A supplemental indenture which changes or eliminates any covenant or other provision of this
Indenture that has expressly been included solely for the benefit of one or more particular series
of Securities, or that modifies the rights of the Holders of Securities of such series with respect
to such covenant or other provision, shall be deemed not to affect the rights under this Indenture
of the Holders of Securities of any other series.

     Notwithstanding the foregoing, the provisions under this Indenture relating to the Company’s
obligations to make a Change of Control Offer may be waived or amended with the written consent of
the Holders of a majority in principal amount of the 65⁄8% Notes.

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

     An amendment under this Section 902 may not make any change that would adversely affect the
rights under Article Fourteen or Sixteen of any holder of Senior Indebtedness then outstanding
unless the holders of such Senior Indebtedness (or their Representatives) consent to such change or
unless the notes, debentures, bonds or other similar instruments evidencing such Senior
Indebtedness so permit.

     SECTION 6.       Amendments to Article Ten of the Original Indenture.

               (a)       Section 1001 of the Original Indenture is amended with respect to the 65⁄8% Notes by adding
the following paragraphs thereto:

City time, on such date the Trustee or the Paying Agent holds in accordance with this Indenture
money, in immediately available funds, sufficient to pay all principal and interest then due and
the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to
the Noteholders on that date pursuant to the terms of this Indenture.

     The Company shall pay interest on overdue principal at the rate specified therefor in the 65⁄8%
Notes, and it shall pay interest on overdue installments of interest at the same rate to the extent
lawful.

               (b)       Section 1005 of the Original Indenture is amended with respect to the 65⁄8% Notes by
substituting the word “Company” for the words “Board of Directors” therein.

               (c)       Article Ten of the Original Indenture is amended with respect to the 65⁄8% Notes by adding
Sections 1009 through 1018, inclusive, as follows:

Section 1009. Commission Reports.

38

 

     Notwithstanding that the Company may not be subject to the reporting requirements of Section
13 or 15(d) of the Exchange Act, the Company shall file with the Commission (to the extent the
Commission will accept such filings) and provide the Trustee and Noteholders with such annual
reports and such information, documents and other reports as are specified in Sections 13 and 15(d)
of the Exchange Act and applicable to a U.S. corporation subject to such Sections (but without

and provided at the times specified for the filing of such information, documents and reports under
such Sections.

     Delivery of the reports, information and documents specified in the preceding paragraph to the
Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute
constructive notice of any information contained therein or determinable from information contained
therein, including the Company’s compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely on Officers’ Certificates).

Section 1010. Limitation on Indebtedness.

     (a)       The Company shall not, and shall not permit any Restricted Subsidiary to, Incur, directly
or indirectly, any Indebtedness; provided, however, that the Company and the Subsidiary Guarantors
shall be entitled to Incur Indebtedness if, on the date of such Incurrence and after giving effect
thereto on a pro forma basis, no Default has occurred and is continuing and the Consolidated
Coverage Ratio exceeds 2.5 to 1.

Incurrence, the aggregate principal amount of all Indebtedness Incurred under this clause
(1) and then outstanding does not exceed the greater of (A) $650 million less the sum of all
principal payments with respect to such Indebtedness pursuant to Section 1014(a)(3)(A) and
(B) $200 million plus 20% of ACNTA as of the date of such Incurrence;

     (2)      Indebtedness owed to and held by the Company or a Wholly Owned Subsidiary;

results in any such Wholly Owned Subsidiary ceasing to be a Wholly Owned Subsidiary or any
subsequent transfer of such Indebtedness (other than to the Company or a Wholly Owned
Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Indebtedness
by the obligor thereon and (B) if the Company is the obligor on such Indebtedness, unless
such Indebtedness is owing to a Subsidiary Guarantor, such Indebtedness is expressly
subordinated to the prior payment in full in cash of all obligations with respect to the 65⁄8%
Notes;

the funds or credit support utilized to consummate, the transaction or series of related
transactions pursuant to which such Subsidiary became a Restricted Subsidiary or was
acquired by the Company); provided, however, that on the date such Subsidiary became a
Restricted Subsidiary or was acquired by the Company and after giving pro forma effect
thereto, the Company would have been able to Incur at least $1.00 of additional Indebtedness
pursuant to Section 1010(a);

     (6)       Refinancing Indebtedness in respect of Indebtedness Incurred pursuant to Section

provided, however, that to the extent such Refinancing Indebtedness directly or indirectly

Refinancing Indebtedness shall be Incurred only by such Restricted Subsidiary or the
Company;

     (11)       Indebtedness consisting of any Guarantee by the Company or a Subsidiary Guarantor

1010(a)) does not exceed $50 million.

     (c)       Notwithstanding the foregoing, the Company shall not, and shall not permit any Subsidiary
Guarantor to, Incur any Indebtedness pursuant to Section 1010(b) if the proceeds thereof are used,
directly or indirectly, to Refinance any Subordinated Obligations of the Company or any Subsidiary
Guarantor unless such Indebtedness shall be subordinated to the 65⁄8% Notes or the applicable
Subsidiary Guaranty to at least the same extent as such Subordinated Obligations.

     (d)       For purposes of determining compliance with this Section 1010, any Indebtedness remaining
outstanding under the Revolving Credit Facility on the Issue Date shall be treated as Incurred on
such date under Section 1010(b)(1). Further, in the event that an item of Indebtedness (or portion
thereof) meets the criteria of more than one of the categories of Indebtedness described above
(including Section 1010(a)), (1) the Company, in its sole discretion, may classify (or later
reclassify in whole or in part) such item of Indebtedness (or any portion thereof) as of the time

     (e)       Notwithstanding Section 1010(a) or 1010(b), the Company shall not, and shall not permit
any Subsidiary Guarantor to, Incur, directly or indirectly, any Indebtedness if such Indebtedness
is contractually subordinate or junior in right of payment to any Senior Indebtedness of such
Person, unless such Indebtedness is Senior Subordinated Indebtedness of such Person or is expressly
subordinated in right of payment to Senior Subordinated

41

 

Indebtedness of such Person. Unsecured Indebtedness shall not be deemed to be subordinated or
junior to Secured Indebtedness merely because it is unsecured.

Section 1011. Limitation on Restricted Payments.

     (a)       The Company shall not, and shall not permit any Restricted Subsidiary, directly or
indirectly, to make a Restricted Payment if at the time the Company or such Restricted Subsidiary

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

     (2)       the Company is not entitled to Incur an additional $1.00 of Indebtedness pursuant

since the 2002 Issue Date would exceed the sum of (without duplication):

     (A)       50% of the Consolidated Net Income accrued during the period (treated as
one accounting period) from July 1, 2002 to the end of the most recent fiscal
quarter for which financial statements of the Company are publicly available prior
to the date of such Restricted Payment (or, in case such Consolidated Net Income

     (B)       100% of the aggregate Net Cash Proceeds or the fair market value of
property other than cash (including Capital Stock of Persons engaged in the Oil and
Gas Business or assets used in the Oil and Gas Business) received by the Company
from the issuance or sale of its Capital Stock (other than Disqualified Stock)
subsequent to the 2002 Issue Date (other than an issuance or sale (w) in connection
with the acquisition of EEX by merger, (x) to a Subsidiary of the Company, (y) to an
employee stock ownership plan or (z) to a trust established by the Company or any of
its Subsidiaries for the benefit of their employees) and 100% of any capital
contribution received by the Company from its shareholders subsequent to the 2002
Issue Date; plus

     (C)       the aggregate Net Cash Proceeds received by the Company subsequent to the
2002 Issue Date from the issuance or sale of its Capital Stock (other than
Disqualified Stock) to an employee stock ownership plan or to a trust established by
the Company or any of its Subsidiaries for the benefit of their employees; provided,
however, that if such employee stock ownership plan or trust Incurs any Indebtedness
to finance the purchase of such Capital Stock, such aggregate amount shall be
limited to the excess of such Net Cash Proceeds over the amount of such Indebtedness
plus an amount equal to any increase in the Consolidated Net Worth of the Company
resulting from principal repayments made from time to time by such employee stock
ownership plan or trust with respect to such Indebtedness; plus

42

 

     (D)       the amount by which Indebtedness of the Company is reduced on the Company’s
balance sheet upon the conversion or exchange (other than by a Subsidiary of the
Company) subsequent to the 2002 Issue Date of any Indebtedness of the Company
convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the
Company (less the amount of any cash, or the fair value of any other property,
distributed by the Company upon such conversion or exchange); provided, however,
that the foregoing amount shall not exceed the Net Cash Proceeds received by the
Company or any Restricted Subsidiary from the sale of such Indebtedness (excluding
Net Cash Proceeds from sales to a Subsidiary of the Company or to an employee stock

that to the extent the foregoing sum exceeds, in the case of any such Person or
Unrestricted Subsidiary, the amount of Investments (excluding Permitted Investments)
previously made (and treated as a Restricted Payment) by the Company or any
Restricted Subsidiary in such Person or Unrestricted Subsidiary, such excess shall
not be included in this clause (E) unless the amount represented by such excess has
not been and will not be taken into account in one of clauses (A)-(D) of this
Section 1011(a); plus

however, that at the time of payment of such dividend, no other Default shall have occurred

     (6)       repurchases, acquisitions or retirements of shares of Company common stock deemed
to occur upon the exercise of stock options or similar rights issued under employee benefit
plans when shares are surrendered to pay all or a portion of the exercise price or to

Restricted Payments; or

     (9)       any redemption pursuant to a Qualified Redemption Transaction; provided, however,
that such redemption shall be included in the calculation of the amount of Restricted
Payments at the time of the redemption.

date of the Restricted Payment of the assets proposed to be transferred by the Company or such
Restricted Subsidiary, as the case may be, in accordance with the Restricted Payment.

consideration in, or to provide all or any portion of the funds or credit support utilized
to consummate, the transaction or series of related transactions pursuant to which such
Restricted Subsidiary became a Restricted Subsidiary or was acquired by the Company) and
outstanding on such date;

(C) or Section 1012(2)(B); provided, however, that the encumbrances and restrictions with
respect to such Restricted Subsidiary contained in any such refinancing agreement or
amendment, modification, restatement, renewal, increase, supplement, replacement or
extension agreement are not materially more restrictive, taken as a whole, than encumbrances
and restrictions with respect to such Restricted Subsidiary contained in such predecessor
agreements;

     (D)       any customary encumbrance or restriction with respect to a Restricted Subsidiary
imposed pursuant to a merger agreement or an agreement entered into for the sale or
disposition of the Capital Stock or assets of such Restricted Subsidiary pending the closing
of such sale or disposition;

     (E)       customary encumbrances and restrictions contained in agreements of the types

respect to the disposition or distribution of assets, each contained in corporate charters,
bylaws, stockholders’ agreements, limited liability company agreements, partnership
agreements, joint venture agreements and other similar agreements entered into in the
ordinary course of business of the Company and its Restricted Subsidiaries; and

     (2)       with respect to clause (c) only,

     (A)       any such encumbrance or restriction consisting of customary nonassignment
provisions (including provisions forbidding subletting or sublicensing) in leases governing

     (B)       any encumbrance or restriction contained in credit agreements, security agreements

     (C)       encumbrances and restrictions contained in any agreement, instrument or Capital
Stock assumed by the Company or any of its Restricted Subsidiaries or for which any of them
becomes liable as in effect at the time of such transaction (except to the extent such
agreement, instrument or Capital Stock was entered into in connection with or in
contemplation of such transaction), which encumbrances and restrictions are not applicable
to any assets other than assets acquired in connection with such transaction and all
improvements, additions and accessions thereto and products and proceeds thereof;

     (D)       restrictions on cash or other deposits imposed by customers under contracts entered
into in the ordinary course of business;

     (E)       encumbrances and restrictions contained in contracts entered into in the ordinary
course of business, not relating to any Indebtedness, and that do not, individually or in
the aggregate, detract from the value of, or from the ability of the Company and the
Restricted Subsidiaries to realize the value of, property or assets of the Company or any
Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary;
and

     (F)       restrictions on the transfer of property or assets required by any regulatory

indirectly, create, incur, assume or suffer to exist or become effective any Lien securing
Indebtedness of any kind except for Permitted Liens, on or with respect to any of its assets,
whether owned at the Issue Date or thereafter acquired, unless (A) in the case of any Lien securing
Subordinated Obligations, the 65⁄8% Notes are secured by a Lien on such assets that is senior in
priority to such Lien and (B) in the case of any other Lien, the 65⁄8% Notes are either secured
equally and ratably with such Indebtedness or are secured by a Lien on such assets that is senior
in priority to such Lien.

Section 1014. Limitation on Sales of Assets and Subsidiary Stock.

     (a)       The Company shall not, and shall not permit any Restricted Subsidiary to, directly or
indirectly, consummate any Asset Disposition unless:

     (1)       the Company or such Restricted Subsidiary receives consideration at the time of
such Asset Disposition at least equal to the fair market value (including the value of all
non-cash consideration) as determined in good faith by the Board of Directors, an Officer or
an officer of such Restricted Subsidiary with responsibility for such transaction, which
determination shall be conclusive evidence of compliance with this provision, of the shares
or assets subject to such Asset Disposition;

47

 

     (2)       at least 75% of the consideration thereof received by the Company or such
Restricted Subsidiary is in the form of cash, cash equivalents, oil and natural gas
properties or capital assets to be used by the Company or any Restricted Subsidiary in the
Oil and Gas Business; and

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

     (A)       first, to the extent the Company so elects (or is required by the terms of any
Indebtedness), to prepay, repay, purchase, repurchase, redeem, defease or otherwise acquire
or retire for value Senior Indebtedness of the Company or any Subsidiary Guarantor or
Indebtedness (other than Disqualified Stock) of a Wholly Owned Subsidiary that is not a
Subsidiary Guarantor (in each case other than Indebtedness owed to the Company or an
Affiliate of the Company) within one year from the later of the date of such Asset
Disposition or the receipt of such Net Available Cash;

     (B)       second, to the extent of the balance of such Net Available Cash after application
in accordance with clause (A), to the extent the Company so elects, to acquire Additional
Assets or make capital expenditures in the Oil and Gas Business within one year from the
later of the date of such Asset Disposition or the receipt of such Net Available Cash; and

     (C)       third, to the extent of the balance of such Net Available Cash after application in
accordance with clauses (A) and (B), to make an offer to the Holders of the 65⁄8% Notes (and
to holders of other Senior Subordinated Indebtedness of the Company designated by the
Company) to purchase 65⁄8% Notes (and such other Senior Subordinated Indebtedness of the
Company) pursuant to and subject to the conditions of this Section 1014;

provided, however, that in connection with any prepayment, repayment, purchase, repurchase,
redemption, defeasance or other acquisition or retirement for value of Indebtedness pursuant to
clause (A) or (C) of this Section 1014(a)(3), the Company or such Restricted Subsidiary shall
permanently retire such Indebtedness and shall cause the related loan commitment (if any) to be
permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased.

     Notwithstanding the foregoing provisions of this Section 1014, the Company and the Restricted
Subsidiaries shall not be required to apply any Net Available Cash in accordance with this Section
1014 except to the extent that the aggregate Net Available Cash from all Asset Dispositions which
is not applied in accordance with this Section 1014(a) exceeds $20 million. Pending application of
Net Available Cash pursuant to this Section 1014(a), such Net Available Cash shall be invested in
Temporary Cash Investments or applied to temporarily reduce revolving credit indebtedness.

     For the purposes of clause (a)(2) of this Section 1014, the following are deemed to be cash or
cash equivalents: (1) the release of, pursuant to a novation or other agreement, or the discharge
of, the Company or such Restricted Subsidiary from all liability on Indebtedness in

48

 

connection with such Asset Disposition; and (2) securities received by the Company or any
Restricted Subsidiary from the transferee that are converted by the Company or such Restricted
Subsidiary into cash within 120 days of their receipt.

     Notwithstanding the foregoing, the 75% limitation referred to in paragraph (a)(2) of this
Section 1014 shall be deemed satisfied with respect to any Asset Disposition in which the cash or
cash equivalents portion of the consideration received therefrom, determined in accordance with the
foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds
would have been had such Asset Disposition complied with the aforementioned 75% limitation.

     The requirement of Section 1014(a)(3)(B) shall be deemed satisfied if an agreement (including
a lease, whether a capital lease or an operating lease) committing to make the acquisitions or
expenditures referred to therein is entered into by the Company or its Restricted Subsidiary within
the time period specified in such clause and such Net Available Cash is subsequently applied in
accordance with such agreement within six months following such agreement.

     (b)       In the event of an Asset Disposition that requires the purchase of 65⁄8% Notes (and other
Senior Subordinated Indebtedness of the Company) pursuant to Section 1014(a)(3)(C), the Company
shall make such offer to purchase 65⁄8% Notes (the “Offer”) on or before the 366th day after the
later of the date of such Asset Disposition or the receipt of such Net Available Cash, and will
purchase 65⁄8% Notes tendered pursuant to the Offer by the Company for the 65⁄8% Notes (and such other
Senior Subordinated Indebtedness of the Company) at a purchase price of 100% of their principal
amount (or, in the event such other Senior Subordinated Indebtedness of the Company was issued with
significant original issue discount, 100% of the accreted value thereof) without premium, plus
accrued but unpaid interest (or, in respect of such other Senior Subordinated Indebtedness of the
Company, such lesser price, if any, as may be provided for by the terms of such Senior Subordinated
Indebtedness of the Company) in accordance with the procedures (including prorating in the event of
oversubscription) set forth in this Indenture. If the aggregate purchase price of 65⁄8% Notes and any
other Senior Subordinated Indebtedness tendered exceeds the Net Available Cash allotted to their
purchase, the Company shall select the 65⁄8% Notes and other Senior Subordinated Indebtedness to be
purchased on a pro rata basis but in round denominations, which in the case of the 65⁄8% Notes shall
be denominations of $1,000 principal amount or multiples thereof. The Company shall not be required
to make such an Offer to purchase 65⁄8% Notes (and other Senior Subordinated Indebtedness of the
Company) pursuant to this Section 1014 if the Net Available Cash available therefor is less than
$20 million (which lesser amount shall be carried forward for purposes of determining whether such
an Offer is required with respect to the Net Available Cash from any subsequent Asset Disposition).

     (c)       (1)      Promptly, and in any event within 10 days after the Company becomes obligated to make
an Offer, the Company shall deliver to the Trustee and send, by first-class mail to each Holder, a
written notice stating that the Holder may elect to have its 65⁄8% Notes purchased by the Company
either in whole or in part (subject to prorating as described in Section 1014(b) in the event the
Offer is oversubscribed) in integral multiples of $1,000 of principal amount, at the applicable
purchase price. The notice shall specify a purchase date not less than 30 days nor more than 60
days after the date of such notice (the “Purchase Date”) and shall

49

 

contain such information concerning the business of the Company which the Company in good
faith believes will enable such Holders to make an informed decision and all instructions and
materials necessary to tender 65⁄8% Notes pursuant to the Offer, together with the information
contained in clause (3).

     (2)       Not later than the date upon which written notice of an Offer is delivered to the
Trustee as provided above, the Company shall deliver to the Trustee an Officers’ Certificate
as to (A) the amount of the Offer (the “Offer Amount”), including information as to any
other Senior Subordinated Indebtedness included in the Offer, (B) the allocation of the Net
Available Cash from the Asset Dispositions pursuant to which such Offer is being made and
(C) the compliance of such allocation with the provisions of Section 1014(a) and (b). On or
before 11:00 a.m., New York City time, on the Purchase Date, the Company shall irrevocably
deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust) immediately available funds in an amount equal to
the Offer Amount to be held for payment in accordance with the provisions of this Section.
If the Offer includes other Senior Subordinated Indebtedness, the deposit described in the
preceding sentence may be made with any other paying agent pursuant to arrangements
satisfactory to the Trustee. Upon the expiration of the period for which the Offer remains
open (the “Offer Period”), the Company shall deliver to the Trustee for cancellation the 65⁄8%
Notes or portions thereof which have been properly tendered to and are to be accepted by the
Company. The Trustee shall, on the Purchase Date, mail or deliver payment (or cause the
delivery of payment) to each tendering Holder in the amount of the purchase price. In the
event that the aggregate purchase price of the 65⁄8% Notes delivered by the Company to the
Trustee is less than the Offer Amount applicable to the 65⁄8% Notes, the Trustee shall deliver
the excess to the Company immediately after the expiration of the Offer Period. Upon
completion of an Offer, Net Available Cash shall be deemed to be reduced by the Offer
Amount.

     (3)       Holders electing to have an 65⁄8% Notes purchased shall be required to surrender the
65⁄8% Note, with the form “Option of Holder to Elect Purchase” on the reverse duly completed,
to the Company at the address specified in the notice at least three Business Days prior to
the Purchase Date. Holders shall be entitled to withdraw their election if the Trustee or
the Company receives not later than one Business Day prior to the Purchase Date, a facsimile
transmission or letter setting forth the name of the Holder, the principal amount of the 65⁄8%
Notes which was delivered for purchase by the Holder and a statement that such Holder is
withdrawing its election to have such 65⁄8% Notes purchased. Holders whose Securities are
purchased only in part shall be issued new 65⁄8% Notes equal in principal amount to the
unpurchased portion of the 65⁄8% Notes surrendered.

     (4)       At the time the Company delivers 65⁄8% Notes to the Trustee which are to be accepted
for purchase, the Company shall also deliver an Officers’ Certificate stating that such 65⁄8%
Notes are to be accepted by the Company pursuant to and in accordance with the terms of this
Section. An 65⁄8% Note shall be deemed to have been accepted for purchase at the time the
Trustee, directly or through an agent, mails or delivers payment therefor to the
surrendering Holder.

50

 

     (d)       The Company shall comply, to the extent applicable, with the requirements of Section 14(e)
of the Exchange Act and any other securities laws or regulations in connection with the repurchase
of 65⁄8% Notes pursuant to this Section. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its obligations under this
Section by virtue of its compliance with such securities laws or regulations.

Section 1015. Limitation on Affiliate Transactions.

     (a)       The Company shall not, and shall not permit any Restricted Subsidiary to, enter into any
transaction (including the purchase, sale, lease or exchange of any property, employee compensation
arrangements or the rendering of any service) with, or for the benefit of, any Affiliate of the
Company (an “Affiliate Transaction”) unless:

     (1)       the terms of the Affiliate Transaction are no less favorable to the Company or such
Restricted Subsidiary than those that could reasonably be expected to be obtained at the
time of the Affiliate Transaction in arm’s-length dealings with a Person who is not an
Affiliate;

     (2)       if such Affiliate Transaction involves an amount in excess of $15 million, the
terms of the Affiliate Transaction are set forth in writing and a majority of the
non-employee directors of the Company disinterested with respect to such Affiliate
Transaction shall have determined in good faith that the criteria set forth in clause (1)
are satisfied and shall have approved the relevant Affiliate Transaction as evidenced by a
resolution of the Board of Directors; and

     (3)       if such Affiliate Transaction involves an amount in excess of $30 million, the
Board of Directors shall have received a written opinion from an Independent Qualified Party
to the effect that such Affiliate Transaction is fair, from a financial standpoint, to the
Company and its Restricted Subsidiaries or is not less favorable to the Company and its
Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an
arm’s-length transaction with a Person who was not an Affiliate.

     (b)       The provisions of Section 1015(a) shall not prohibit:

     (1)       any Investment or other Restricted Payment, in each case not prohibited to be made
pursuant to Section 1011;

     (2)       any issuance of securities, or other payments, awards or grants in cash, securities
or otherwise pursuant to, or the funding of, employment arrangements, stock options and
stock ownership plans and other benefit plans approved by the Board of Directors;

     (3)       loans or advances to officers, directors and employees who are Affiliates in the
ordinary course of business of the Company or its Restricted Subsidiaries, but in

51

 

any event not to exceed $3.0 million in the aggregate outstanding at any one time;

     (4)       any transaction between or among the Company, a Restricted Subsidiary or joint
venture or similar Person that would constitute an Affiliate Transaction solely because the
Company or a Restricted Subsidiary owns an equity interest in or otherwise controls such
Restricted Subsidiary, joint venture or similar Person;

     (5)       the issuance or sale of any Capital Stock (other than Disqualified Stock) of the
Company;

     (6)       reasonable fees and reasonable compensation paid to, and indemnity and similar
arrangements provided on behalf of, officers, directors and employees of the Company or any
Restricted Subsidiary as determined in good faith by the Board of Directors or the Company’s
senior management; and

     (7)       any agreement as in effect on the Issue Date and described in the Prospectus, or
any renewals or extensions of any such agreement (so long as such renewals or extensions are
not less favorable to the Company or the Restricted Subsidiaries) and the transactions
evidenced thereby.

     Section 1016. Change of Control.

     (a)       Upon the occurrence of a Change of Control, then unless the Company shall have exercised
its right to redeem all the 65⁄8% Notes, each Holder shall have the right to require that the Company
repurchase such Holder’s 65⁄8% Notes at a purchase price in cash equal to 101% of the principal
amount thereof on the date of the purchase plus accrued and unpaid interest, if any, to the date of
purchase (subject to the right of holders of record on the relevant record date to receive interest
due on the relevant Interest Payment Date), in accordance with the terms contemplated in Section
1016(b).

     (b)       Unless the Company has exercised its right to redeem all the 65⁄8% Notes and shall have
delivered an irrevocable notice of redemption to the Trustee, then within 30 days following any
Change of Control, the Company shall mail a notice to each Holder with a copy to the Trustee (the
“Change of Control Offer”) stating:

     (1)       that a Change of Control has occurred and that such Holder has the right to require
the Company to purchase such Holder’s 65⁄8% Notes at a purchase price in cash equal to 101% of
the principal amount thereof on the date of purchase, plus accrued and unpaid interest, if
any, to the date of purchase (subject to the right of holders of record on the relevant
record date to receive interest on the relevant Interest Payment Date);

     (2)       the circumstances and relevant facts regarding such Change of Control (including
information with respect to pro forma historical income, cash flow and capitalization, in
each case after giving effect to such Change of Control);

     (3)       the purchase date (which shall be no earlier than 30 days nor later than 60

52

 

days from the date such notice is mailed); and

     (4)       the instructions, as determined by the Company, consistent with this Section 1016,
that a Holder must follow in order to have its 65⁄8% Notes purchased.

     In the event that at the time of a Change of Control the terms of any Senior Indebtedness of
the Company (including the Revolving Credit Facility) restrict or prohibit the repurchase of 65⁄8%
Notes following such Change of Control pursuant to this Section 1016, then prior to the mailing of
such notice to Holders but in any event within 30 days following any Change of Control, the Company
shall (1) repay in full all such Senior Indebtedness or (2) obtain the requisite consents under the
agreements governing such Senior Indebtedness to permit such repurchase of the 65⁄8% Notes.

     (c)       Holders electing to have an 65⁄8% Note purchased will be required to surrender the 65⁄8% Note,
with the “Option of Holder to Elect Purchase” on the reverse form duly completed, to the Company at
the address specified in the notice at least three Business Days prior to the purchase date.
Holders will be entitled to withdraw their election if the Trustee or the Company receives not
later than one Business Day prior to the purchase date, a facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the 65⁄8% Note which was delivered for purchase
by the Holder and a statement that such Holder is withdrawing its election to have such 65⁄8% Note
purchased.

     (d)       On the purchase date, all 65⁄8% Notes purchased by the Company under this Section shall be
delivered by the Company to the Trustee for cancellation, and the Company shall pay the purchase
price plus accrued and unpaid interest, if any, to the Holders entitled thereto.

     (e)       Notwithstanding the foregoing provisions of this Section, the Company shall not be
required to make a Change of Control Offer following 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 Section 1016 and purchases all 65⁄8% Notes validly tendered and not
withdrawn under such Change of Control Offer.

     (f)       The Company shall comply, to the extent applicable, with the requirements of Section 14(e)
of the Exchange Act and any other securities laws or regulations in connection with the repurchase
of 65⁄8% Notes as a result of a Change of Control. To the extent that the provisions of any
securities laws or regulations conflict with provisions of this Section, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to have breached its
obligations under this Section by virtue of its compliance with such securities laws or
regulations.

Section 1017. Future Guarantors.

     The Company shall cause each Restricted Subsidiary that Guarantees or secures any Indebtedness
of the Company to, at the same time, execute and deliver to the Trustee a Guaranty Agreement
pursuant to which such Restricted Subsidiary will Guarantee payment of the Securities on the same
terms and conditions as those set forth in this Indenture.

53

 

Section 1018. Covenant Suspension.

     (a)      During any period that the 65⁄8% Notes have a rating equal to or higher than BBB- by S&P and
Baa3 by Moody’s (each, an “Investment Grade Rating”) and no Default has occurred and is continuing,
the Company and the Restricted Subsidiaries will not be subject to Sections 1010(a) through (d),
1011, 1012, 1014, 1015, 1017 and 801(a)(3) (collectively, the “Suspended Covenants”).

     (b)      In the event that the Company and the Restricted Subsidiaries are not subject to the
Suspended Covenants for any period of time as a result of the operation of clause (a) of this
Section 1018, and subsequently one or both of S&P and Moody’s downgrades the rating assigned to the
65⁄8% Notes below their respective Investment Grade Rating, then the Company and the Restricted
Subsidiaries will thereafter again be subject to the Suspended Covenants (subject to subsequent
suspension of the 65⁄8% Notes again receive Investment Grade Ratings), and, with respect to
Restricted Payments proposed to be made after the time of such downgrade, the permissibility of
such proposed Restricted Payments will be calculated in accordance with Section 1011 as though
Section 1011 had been in effect since the Issue Date, it being understood, however, that no actions
taken by the Company or any Restricted Subsidiary during the suspension period shall constitute a
Default or an Event of Default under the Suspended Covenants.

     SECTION 7.       Amendments to Article Eleven of the Original Indenture. 

     (a)       Section 1105 of the Original Indenture is amended with respect to the 65⁄8% Notes in its
entirety to read as follows:

     On or prior to 11:00 a.m., New York City time, on the Redemption Date for any
65⁄8% Notes, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money, in immediately available funds,
sufficient to pay the Redemption Price of and accrued interest on (subject to the
right of Holders of record on the relevant record date to receive interest due on
the relevant Interest Payment Date that is on or prior to the Redemption Date) such
Securities or any portions thereof that are to be redeemed on that date, it being
understood that the amount of money to be deposited by the Company in relation to a
mandatory redemption pursuant to Section 1109 shall take into consideration the
amount of money deposited by the Escrow Agent with the Trustee or a Paying Agent to
fund such redemption.

     (b)       Section 1107 of the Original Indenture is amended with respect to the 65⁄8% Notes to add the
following paragraph thereto:

     Any 65⁄8% Note of $1,000 or less principal amount shall be redeemed only as a
whole and not in part.

54

 

     (c)       Article Eleven of the Original Indenture is amended with respect to the 65⁄8% Notes by
adding Sections 1108, 1109 and 1110 as follows:

Section 1108. Optional Redemption.

     (a)       Except as set forth in the following paragraphs of this Section 1108, the 65⁄8% Notes will
not be redeemable at the option of the Company prior to April 15, 2011. Starting on that date, the
Company may redeem all or any portion of the 65⁄8% Notes, upon no less than 30 nor more than 60 days’
prior notice, at the Redemption Prices set forth below, plus accrued and unpaid interest, if any,
to the Redemption Date (subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date). The following prices are for 65⁄8%
Notes redeemed during the 12-month period commencing on April 15 of the years set forth below, and
are expressed as percentages of principal amount:

	 	 	 	 	 
	 	 	Redemption
	Year	 	Price
	2011
	 	 	103.313	%
	2012
	 	 	102.208	%
	2013
	 	 	101.104	%
	2014 and thereafter
	 	 	100.000	%

     (b)       The Company may on any one or more occasions prior to April 15, 2009, redeem up to 35% of
the aggregate principal amount of the 65⁄8% Notes (including any Additional 65⁄8% Notes) originally
issued prior to the Redemption Date with the Net Proceeds of one or more Public Equity Offerings at
a Redemption Price of 106.625% of the principal amount thereof, plus accrued and unpaid interest,
if any, to the date of redemption, subject to the right of holders of record on the relevant record
date to receive interest due on the relevant Interest Payment Date, provided that at least 65% of
the aggregate principal amount of the 65⁄8% Notes (including any Additional 65⁄8% Notes) originally
issued prior to the Redemption Date remains Outstanding after the occurrence of such redemption.
Any such redemption shall occur not later than 90 days after the date of the closing of any such
Public Equity Offering upon not less than 30 nor more than 60 days’ prior notice. The redemption
shall be made in accordance with procedures set forth in this Indenture.

     (c)       At any time prior to April 15, 2011, the Company may redeem the 65⁄8% Notes at its option,
as a whole, at a Redemption Price equal to 100% of the principal amount thereof plus the Applicable
Premium as of, and accrued and unpaid interest to, the Redemption Date. For purposes of Section
1104, it shall be sufficient if a notice of redemption pursuant to this Section 1108(c) shall
describe the method for determining the Redemption Price in lieu of stating the Redemption Price.

Section 1109. No Mandatory Sinking Fund.

     There will be no mandatory sinking fund payments for the 65⁄8% Notes.

55

 

     SECTION 8.       Amendments to Article Thirteen the Original Indenture. 

     (a)       Section 1302 of the Original Indenture is amended in its entirety with respect to the 65⁄8%
Notes to read as follows:

Section 1302. Defeasance and Discharge.

     Upon the Company’s exercise of its option to have this Section applied to the 65⁄8% Notes, (i)
the Company shall be deemed to have been discharged from its obligations hereunder as provided in
this Section, (ii) payment of the 65⁄8% Notes may not be accelerated because of an Event of Default
with respect thereto and (iii) the provisions of Articles Fourteen through Sixteen shall cease to
be effective with respect to the 65⁄8% Notes as provided in this Section on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called “Defeasance”). For this
purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the
entire indebtedness represented by the 65⁄8% Notes and to have satisfied all its other obligations
under the 65⁄8% Notes and this Indenture insofar as the 65⁄8% Notes are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the same), subject to
the following, which shall survive until otherwise terminated or discharged hereunder: (1) the
rights of Holders of the 65⁄8% Notes to receive, solely from the trust fund described in Section 1304
and as more fully set forth in such Section, payments in respect of the principal of and any
premium and interest on the 65⁄8% Notes when payments are due, (2) the Company’s obligations with
respect to the 65⁄8% Notes under Sections 304, 305, 306, 1002 and 1003, (3) the rights, powers,
trusts, duties and immunities of the Trustee hereunder and (4) this Article. Subject to compliance
with this Article, the Company may exercise its option (if any) to have this Section applied to the
65⁄8% Notes notwithstanding the prior exercise of its option (if any) to have Section 1303 applied to
the 65⁄8% Notes.

     (b)       Section 1303 of the Original Indenture is amended in its entirety with respect to the 65⁄8%
Notes to read as follows:

Section 1303. Covenant Defeasance.

     Upon the Company’s exercise of its option to have this Section applied to the 65⁄8% Notes, (i)
the Company shall be released from its obligations under Section 801(a)(3), Sections 1005 through
1017, inclusive, (ii) payment of the Notes may not be accelerated because of an Event of Default
specified in clause (4), clause (5) (with respect only to Subsidiary Guarantors or Significant
Subsidiaries), clause (6) (with respect only to Subsidiary Guarantors or Significant Subsidiaries),
clause (7), clause (8) or clause (9) of Section 501 or because of the failure of the Company to
comply with Section 801(a)(3) and (iii) the provisions of Articles Fourteen through Sixteen shall
cease to be effective with respect to the 65⁄8% Notes as provided in this Section on and after the
date the conditions set forth in Section 1304 are satisfied (hereinafter called “Covenant
Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to the 65⁄8%
Notes, the Company may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such specified Section or Article Fourteen, Fifteen or
Sixteen, whether directly or indirectly by reason of any reference elsewhere herein to any such
Section or Article Fourteen, Fifteen or Sixteen, or by reason of any reference in any

56

 

such Section or Article to any other provision herein or in any other document, but the
remainder of this Indenture and the 65⁄8% Notes shall be unaffected thereby.

     SECTION 9.       Amendments to Article Fourteen of the Original Indenture. 

     (a) Article Fourteen of the Original Indenture is superseded with respect to the 65⁄8% Notes by
the following provisions:

ARTICLE FOURTEEN

Subordination

Section 1401. Agreement to Subordinate.

     The Company agrees, and each Noteholder by accepting an 65⁄8% Note agrees, that the payment of
the principal of, premium, if any, and interest on the 65⁄8% Notes and any other payment obligation
of the Company in respect of the 65⁄8% Notes (including any obligation to purchase 65⁄8% Notes) is
subordinated in right of payment, to the extent and in the manner provided in this Article
Fourteen, to the prior payment in full of all Senior Indebtedness of the Company, including the
obligations of the Company under the Revolving Credit Facility, and that the subordination is for
the benefit of and shall be enforceable directly by the holders of such Senior Indebtedness. The
65⁄8% Notes shall in all respects rank pari passu with all other Senior Subordinated Indebtedness of
the Company (including, without limitation, the 2012 Notes and 2014 Notes) and only Indebtedness of
the Company that is Senior Indebtedness of the Company shall rank senior to the 65⁄8% Notes in
accordance with the provisions set forth herein. All provisions of this Article Fourteen shall be
subject to Section 1412.

Section 1402. Liquidation, Dissolution, Bankruptcy.

     Upon any payment or distribution of the assets of the Company upon a liquidation, dissolution
or reorganization of or similar proceeding relating to the Company or its property:

     (1)       holders of Senior Indebtedness of the Company shall be entitled to receive payment in
full in cash or cash equivalents of such Senior Indebtedness before Noteholders shall be entitled
to receive any payment; and

     (2)       until such Senior Indebtedness is paid in full in cash or cash equivalents, any payment or
distribution to which Noteholders would be entitled but for this Article Fourteen shall be made to
holders of such Senior Indebtedness as their interests may appear, except that Noteholders may
receive shares of stock and any debt securities that are subordinated to such Senior Indebtedness
to at least the same extent as the 65⁄8% Notes.

Section 1403. Default on Senior Indebtedness of the Company.

     The Company shall not pay the principal of, premium, if any, or interest on the 65⁄8% Notes or
any other payment obligation in respect of the 65⁄8% Notes (including any obligation to purchase the
65⁄8% Notes) or make any deposit pursuant to Article Four or Thirteen and may not purchase, redeem or
otherwise retire any 65⁄8% Notes (collectively, “pay the 65⁄8% Notes”) if

57

 

either of the following (a “Payment Default”) occurs: (1) any Obligation on Designated Senior
Indebtedness of the Company is not paid in full when due; or (2) any other default on Designated
Senior Indebtedness of the Company occurs and the maturity of such Designated Senior Indebtedness
is accelerated in accordance with its terms; unless, in either case, the Payment Default has been
cured or waived and any such acceleration has been rescinded or such Designated Senior Indebtedness
has been paid in full in cash or cash equivalents; provided, however, that the Company shall be
entitled to pay the 65⁄8% Notes without regard to the foregoing if the Company and the Trustee
receive written notice approving such payment from the Representatives of all Designated Senior
Indebtedness with respect to which the Payment Default has occurred and is continuing.

     During the continuance of any default (other than a Payment Default) with respect to any
Designated Senior Indebtedness of the Company pursuant to which the maturity thereof may be
accelerated without further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods, the Company shall not pay the 65⁄8%
Notes for a period (a “Payment Blockage Period”) commencing upon the receipt by the Trustee and the
Company of a written notice (a “Blockage Notice”) of such default from the Representative of such
Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period and
ending 179 days thereafter. The Payment Blockage Period shall end earlier if such Payment Blockage
Period is terminated: (1) by written notice to the Trustee and the Company from the Person or
Persons who gave such Blockage Notice; (2) because the default giving rise to such Blockage Notice
is cured, waived or otherwise no longer continuing; or (3) because such Designated Senior
Indebtedness has been discharged or repaid in full in cash or cash equivalents.

     Notwithstanding the provisions described in the preceding paragraph, unless the holders of
such Designated Senior Indebtedness or the Representative of such Designated Senior Indebtedness
shall have accelerated the maturity of such Designated Senior Indebtedness, the Company shall be
permitted to resume payments on the 65⁄8% Notes after the end of such Payment Blockage Period. The
65⁄8% Notes shall not be subject to more than one Payment Blockage Period in any consecutive 360-day
period irrespective of the number of defaults with respect to Designated Senior Indebtedness of the
Company during such period; provided, however, that in no event may the total number of days during
which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during
any consecutive 360-day period, and there must be 181 days during any consecutive 360-day period
during which no Payment Blockage Period is in effect.

Section 1404. Acceleration of Payment of 65⁄8% Notes.

     If payment of the 65⁄8% Notes is accelerated because of an Event of Default, the Company or the
Trustee shall promptly notify the holders of Designated Senior Indebtedness of the Company (or
their Representatives) of the acceleration.

Section 1405. When Distribution Must Be Paid Over; Reinstatement of Senior Indebtedness.

     If a distribution is made to Noteholders that because of this Article Fourteen should not have
been made to them, the Noteholders who receive the distribution shall hold it in trust for

58

 

holders of Senior Indebtedness of the Company and pay it over to them as their interests may
appear.

     To the extent any payment of or distribution in respect of Senior Indebtedness (whether by or
on behalf of the Company as proceeds of security or enforcement of any right of setoff or
otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any
receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person under any
bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then if such payment or
distribution is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating
trustee, agent or other similar Person, the Senior Indebtedness or part thereof originally intended
to be satisfied shall be deemed to be reinstated and outstanding as if such payment had not
occurred.

Section 1406. Subrogation.

     After all Senior Indebtedness of the Company is paid in full and until the 65⁄8% Notes are paid
in full, Noteholders shall be subrogated to the rights of holders of such Senior Indebtedness to
receive distributions applicable to such Senior Indebtedness. A distribution made under this
Article Fourteen to holders of such Senior Indebtedness which otherwise would have been made to
Noteholders is not, as between the Company and Noteholders, a payment by the Company on such Senior
Indebtedness.

Section 1407. Relative Rights.

     This Article Fourteen defines the relative rights of Noteholders and holders of Senior
Indebtedness of the Company. Nothing in this Indenture shall:

     (1)       impair, as between the Company and Noteholders, the obligation of the Company, which is
absolute and unconditional, to pay principal of and interest on the 65⁄8% Notes in accordance with
their terms; or

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

Section 1408. Subordination May Not Be Impaired by Company.

     No right of any present or future holders of any Senior Indebtedness of the Company to enforce
subordination as provided in this Indenture will at any time in any way be prejudiced or impaired
by noncompliance by the Company with the terms of this Indenture, regardless of any knowledge
thereof that any such holder of Senior Indebtedness may have or otherwise be charged with.

Section 1409. Rights of Trustee and Paying Agent; Rights of Holders of Senior
Indebtedness.

     Notwithstanding Section 1403, the Trustee or Paying Agent shall continue to make payments on
the 65⁄8% Notes and shall not be charged with knowledge of the existence of facts that under this
Article Fourteen would prohibit the making of any such payments unless, not less

59

 

than two Business Days prior to the date of such payment, a Trust Officer of the Trustee
receives notice satisfactory to it that such payments are prohibited by this Article Fourteen. The
Company, the Security Registrar, the Paying Agent, a Representative or a holder of Senior
Indebtedness of the Company shall be entitled to give the notice; provided, however, that, if an
issue of Senior Indebtedness of the Company has a Representative, only the Representative shall be
entitled to give the notice.

     The Trustee in its individual or any other capacity shall be entitled to hold Senior
Indebtedness of the Company with the same rights it would have if it were not Trustee. The Security
Registrar and the Paying Agent shall be entitled to do the same with like rights. The Trustee shall
be entitled to all the rights set forth in this Article Fourteen with respect to any Senior
Indebtedness of the Company which may at any time be held by it, to the same extent as any other
holder of such Senior Indebtedness; and nothing in Article Six shall deprive the Trustee of any of
its rights as such holder. Nothing in this Article Fourteen shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 607.

     The holders of Senior Indebtedness may, at any time and from time to time subject to the terms
of such Senior Indebtedness, without the consent of or notice to the Trustee or the Noteholders,
without incurring responsibility to the Noteholders and without impairing or releasing the
subordination provided in this Indenture or the obligations hereunder of the Noteholders to the
holders of Senior Indebtedness, do any one or more of the following:

     (1)      
change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness or any
instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding or
secured;

     (2)       sell, exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Indebtedness;

     (3)       release any Person liable in any manner for the collection of Senior Indebtedness; and

     (4)       exercise or refrain from exercising any rights against the Company and any other Person.

Section 1410. Distribution or Notice to Representative.

     Whenever any Person is to make a distribution or give a notice to holders of Senior
Indebtedness of the Company, such Person shall be entitled to make such distribution or give such
notice to their Representative (if any).

Section 1411. Article Fourteen Not to Prevent Events of Default or Limit Right to
Accelerate.

     The failure to make a payment pursuant to the 65⁄8% Notes by reason of any provision in this
Article Fourteen shall not be construed as preventing the occurrence of a Default. Nothing in this
Article Fourteen shall have any effect on the right of the Noteholders or the Trustee to accelerate
the maturity of the 65⁄8% Notes.

Section 1412. Trust Moneys Not Subordinated.

60

 

     Notwithstanding anything contained herein to the contrary, payments from either any money or
the proceeds of U.S. Government Obligations held in trust under Article Four or Thirteen by the
Trustee for the payment of principal of and interest on the 65⁄8% Notes shall not be subordinated to
the prior payment of any Senior Indebtedness of the Company or subject to the restrictions set
forth in this Article Fourteen, and none of the Noteholders shall be obligated to pay over any such
amount to the Company or any holder of Senior Indebtedness of the Company or any other creditor of
the Company.

Section 1413. Trustee Entitled to Rely.

     Upon any payment or distribution pursuant to this Article Fourteen, the Trustee and the
Noteholders shall be entitled to rely (1) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 1402 are pending, (2)
upon a certificate of the liquidating trustee or agent or other Person making such payment or
distribution to the Trustee or to the Noteholders or (3) upon the Representatives of Senior
Indebtedness of the Company for the purpose of ascertaining the Persons entitled to participate in
such payment or distribution, the holders of such Senior Indebtedness and other Indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article Fourteen. In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right of any Person as a
holder of Senior Indebtedness of the Company to participate in any payment or distribution pursuant
to this Article Fourteen, the Trustee shall be entitled to request such Person to furnish evidence
to the reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness held by
such Person, the extent to which such Person is entitled to participate in such payment or
distribution and other facts pertinent to the rights of such Person under this Article Fourteen,
and, if such evidence is not furnished, the Trustee shall be entitled to defer any payment to such
Person pending judicial determination as to the right of such Person to receive such payment. The
provisions of Sections 601 and 603 shall be applicable to all actions or omissions of actions by
the Trustee pursuant to this Article Fourteen.

Section 1414. Trustee to Effectuate Subordination.

     Each Noteholder by accepting an 65⁄8% Note authorizes and directs the Trustee on its behalf to
take such action as may be necessary or appropriate to effectuate the subordination provided in
this Article Fourteen and appoints the Trustee as attorney-in-fact for any and all such purposes.

Section 1415. Trustee Not Fiduciary for Holders of Senior Indebtedness of the Company.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness of the Company and shall not be liable to any such holders if it shall mistakenly pay
over or distribute to Noteholders or the Company or any other Person, money or assets to which any
holders of Senior Indebtedness of the Company shall be entitled by virtue of this Article Fourteen
or otherwise.

Section 1416. Reliance by Holders of Senior Indebtedness of the Company on Subordination
Provisions.

61

 

     Each Noteholder by accepting an 65⁄8% Note acknowledges and agrees that the foregoing
subordination provisions are, and are intended to be, an inducement and a consideration to each
holder of any Senior Indebtedness of the Company, whether such Senior Indebtedness was created or
acquired before or after the issuance of the 65⁄8% Notes, to acquire and continue to hold, or to
continue to hold, such Senior Indebtedness and such holder of such Senior Indebtedness shall be
deemed conclusively to have relied on such subordination provisions in acquiring and continuing to
hold, or in continuing to hold, such Senior Indebtedness.

     SECTION 10.       Subsidiary Guaranties.

     (a)       The Original Indenture is amended with respect to the 65⁄8% Notes by adding Articles Fifteen
and Sixteen as follows:

ARTICLE FIFTEEN

Subsidiary Guaranties

Section 1501. Guaranties.

     Each Subsidiary Guarantor hereby unconditionally and irrevocably guarantees, jointly and
severally, to each Holder and to the Trustee and its successors and assigns (a) the full and
punctual payment of principal of and interest on the 65⁄8% Notes when due, whether at Stated
Maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the
Company under this Indenture and the 65⁄8% Notes and (b) the full and punctual performance within
applicable grace periods of all other obligations of the Company under this Indenture and the 65⁄8%
Notes (all the foregoing being hereinafter collectively called the “Guarantied Obligations”). Each
Subsidiary Guarantor further agrees that the Guarantied Obligations may be extended or renewed, in
whole or in part, without notice or further assent from such Subsidiary Guarantor and that such
Subsidiary Guarantor will remain bound under this Article Fifteen notwithstanding any extension or
renewal of any Guarantied Obligation.

     Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the
Company of any of the Guarantied Obligations and also waives notice of protest for nonpayment. Each
Subsidiary Guarantor waives notice of any default under the 65⁄8% Notes or the Guarantied
Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (a)
the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or
remedy against the Company or any other Person under this Indenture, the 65⁄8% Notes or any other
agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver,
amendment or modification of any of the terms or provisions of this Indenture, the 65⁄8% Notes or any
other agreement; (d) the release of any security held by any Holder or the Trustee for the
Guarantied Obligations or any of them; (e) the failure of any Holder or the Trustee to exercise any
right or remedy against any other guarantor of the Guarantied Obligations; or (f) except as set
forth in Section 1506, any change in the ownership of such Subsidiary Guarantor.

     Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty herein constitutes a
guarantee of payment, performance and compliance when due (and not a guarantee of

62

 

collection) and
waives any right to require that any resort be had by any Holder or the Trustee to any security
held for payment of the Guarantied Obligations.

     Each Subsidiary Guaranty is, to the extent and in the manner set forth in Article Sixteen,
subordinated and subject in right of payment to the prior payment in full of the principal of and
premium, if any, and interest on all Senior Indebtedness of the Subsidiary Guarantor giving such
Subsidiary Guaranty and each Subsidiary Guaranty is made subject to such provisions of this
Indenture.

     Except as expressly set forth in Sections 1502 and 1506, the obligations of each Subsidiary
Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination
for any reason, including any claim of waiver, release, surrender, alteration or compromise, and
shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever
or by reason of the invalidity, illegality or unenforceability of the Guarantied Obligations or
otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary
Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any
Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture,
the 65⁄8% Notes or any other agreement, by any waiver or modification of any thereof, by any default,
failure or delay, willful or otherwise, in the performance of the obligations, or by any other act
or thing or omission or delay to do any other act or thing which may or might in any manner or to
any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of
such Subsidiary Guarantor as a matter of law or equity, except for the payment in full of the
Guarantied Obligations.

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

     In furtherance of the foregoing and not in limitation of any other right which any Holder or
the Trustee has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the
failure of the Company to pay the principal of or interest on any Guarantied Obligation when and as
the same shall become due, whether at Stated Maturity, by acceleration, by redemption or otherwise,
or to perform or comply with any other Guarantied Obligation, each Subsidiary Guarantor hereby
promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be
paid, in cash, to the Holders or the Trustee an amount equal to the sum of (1) the unpaid amount of
such Guarantied Obligations, (2) accrued and unpaid interest on such Guarantied Obligations (but
only to the extent not prohibited by law) and (3) all other monetary Guarantied Obligations of the
Company to the Holders and the Trustee.

     Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in
respect of any Guarantied Obligations until payment in full of all Guarantied Obligations and all
obligations to which the Guarantied Obligations are subordinated as provided in Article Sixteen.
Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Guarantied Obligations may
be accelerated as provided in Article Five for the purposes of such Subsidiary Guarantor’s

63

 

Subsidiary Guaranty herein, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Guarantied Obligations, and (y) in the event of any declaration
of acceleration of such Guarantied Obligations as provided in Article Five, such Guarantied
Obligations (whether or not due and payable) shall forthwith become due and payable by such
Subsidiary Guarantor for the purposes of this Section.

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

Section 1502. Limitation on Liability.

     Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate
amount of the Guarantied Obligations with respect to any Subsidiary Guarantor shall not exceed the
maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to
such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors generally.

Section 1503. Successors and Assigns.

     This Article Fifteen shall be binding upon each Subsidiary Guarantor and its successors and
assigns and shall enure to the benefit of the successors and assigns of the Trustee and the Holders
and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights
and privileges conferred upon that party in this Indenture and in the 65⁄8% Notes shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms and conditions of
this Indenture.

Section 1504. No Waiver.

     Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising
any right, power or privilege under this Article Fifteen shall operate as a waiver thereof, nor
shall a single or partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein
expressly specified are cumulative and not exclusive of any other rights, remedies or benefits
which either may have under this Article Fifteen at law, in equity, by statute or otherwise.

Section 1505. Modification.

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

Section 1506. Release of Subsidiary Guarantor.

64

 

     Upon (1) the sale or other disposition (including by way of consolidation or merger) of all of
the Capital Stock of a Subsidiary Guarantor (in each case other than a sale or disposition to the
Company or an Affiliate of the Company) and as permitted by this Indenture, (2) the liquidation and
dissolution of a Subsidiary Guarantor, (3) the exercise by the Company of its option (A) to satisfy
and discharge the Indenture with respect to the 65⁄8% Notes pursuant to Article Four or (B) to
effect Defeasance or Covenant Defeasance pursuant to Article Thirteen or (4) the designation of a
Subsidiary Guarantor as an Unrestricted Subsidiary, such Subsidiary Guarantor shall be deemed
released from all obligations under this Indenture and the 65⁄8% Notes without any further action
required on the part of the Trustee, the Company, such Subsidiary Guarantor or any Holder. At the
request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing
such release.

Section 1507 Contribution.

     Each Subsidiary Guarantor that makes a payment under its Subsidiary Guaranty shall be entitled
upon payment in full of all Guarantied Obligations to a contribution from each other Subsidiary
Guarantor in an amount equal to such other Subsidiary Guarantor’s pro rata portion of such payment
based on the respective net assets of all the Subsidiary Guarantors at the time of such payment
determined in accordance with GAAP.

ARTICLE SIXTEEN

Subordination of Subsidiary Guaranties

Section 1601. Agreement to Subordinate.

     Each Subsidiary Guarantor agrees, and each Noteholder by accepting an 65⁄8% Note agrees, that
the payment of such Subsidiary Guarantor’s Subsidiary Guaranty (including any amounts in respect of
the principal of, premium, if any, or interest on the 65⁄8% Notes and any other payment obligation in
respect of the 65⁄8% Notes, including any obligation of the Company to purchase 65⁄8% Notes) is
subordinated in right of payment, to the extent and in the manner provided in this Article Sixteen,
to the prior payment in full of all Senior Indebtedness of such Subsidiary Guarantor, including
such Subsidiary Guarantor’s Guarantee of Senior Indebtedness of the Company, and that the
subordination is for the benefit of and shall be enforceable directly by the holders of such Senior
Indebtedness. The Guarantied Obligations of a Subsidiary Guarantor shall in all respects rank pari
passu with all other Senior Subordinated Indebtedness of such Subsidiary Guarantor and only
Indebtedness of such Subsidiary Guarantor that is Senior Indebtedness of such Subsidiary Guarantor
shall rank senior to the Guarantied Obligations of such Subsidiary Guarantor in accordance with the
provisions set forth herein. All provisions of this Article Sixteen shall be subject to Section
1612.

Section 1602. Liquidation, Dissolution, Bankruptcy.

     Upon any payment or distribution of the assets of any Subsidiary Guarantor upon a liquidation,
dissolution or reorganization of or similar proceeding relating to such Subsidiary Guarantor or its
property:

65

 

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

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

Section 1603. Default on Senior Indebtedness of Subsidiary Guarantor.

     No Subsidiary Guarantor shall make any payment under its Subsidiary Guaranty, whether in
respect of the principal of, premium, if any, or interest on the 65⁄8% Notes or any other payment
obligation in respect of the 65⁄8% Notes (including any obligation of the Company to purchase 65⁄8%
Notes) or make any deposit pursuant to Article Four or Thirteen and may not purchase, redeem or
otherwise retire or defease any 65⁄8% Notes or other Guarantied Obligations (collectively, “pay its
Subsidiary Guaranty”) if either of the following (a “Payment Default”) occurs (1) any Obligation on
Designated Senior Indebtedness of such Subsidiary Guarantor is not paid in full when due; or (2)
any other default on Designated Senior Indebtedness of such Subsidiary Guarantor occurs and the
maturity of such Designated Senior Indebtedness is accelerated in accordance with its terms;
unless, in either case, the Payment Default has been cured or waived and any such acceleration has
been rescinded or such Designated Senior Indebtedness has been paid in full in cash or cash
equivalents; provided, however, that any Subsidiary Guarantor shall be entitled to pay its
Subsidiary Guaranty without regard to the foregoing if such Subsidiary Guarantor and the Trustee
receive written notice approving such payment from the Representatives of all Designated Senior
Indebtedness with respect to which the Payment Default has occurred and is continuing.

     During the continuance of any default (other than a Payment Default) with respect to any
Designated Senior Indebtedness of such Subsidiary Guarantor pursuant to which the maturity thereof
may be accelerated without further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods, such Subsidiary Guarantor shall
not pay its Subsidiary Guaranty for a period (a “Payment Blockage Period”) commencing upon the
receipt by the Trustee and such Subsidiary Guarantor of written notice (a “Blockage Notice”) of
such default from the Representative of such Designated Senior Indebtedness specifying an election
to effect a Payment Blockage Period and ending 179 days thereafter. The Payment Blockage Period
shall end earlier if such Payment Blockage Period is terminated: (1) by written notice to the
Trustee and such Subsidiary Guarantor from the Person or Persons who gave such Blockage Notice; (2)
because the default giving rise to such Blockage Notice is cured, waived or otherwise no longer
continuing; or (3) because such Designated Senior Indebtedness has been discharged or repaid in
full in cash or cash equivalents.

     Notwithstanding the provisions described in the preceding paragraph, unless the holders of
such Designated Senior Indebtedness giving such Payment Notice or the Representative of

66

 

such Designated Senior Indebtedness shall have accelerated the maturity of such Designated
Senior Indebtedness, any Subsidiary Guarantor shall be permitted to resume payments pursuant to its
Subsidiary Guaranty after the end of such Payment Blockage Period. No Subsidiary Guarantor shall be
subject to more than one Blockage Period in any consecutive 360-day period irrespective of the
number of defaults with respect to Designated Senior Indebtedness of such Subsidiary Guarantor
during such period; provided, however, that in no event may the total number of days during which
any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any
consecutive 360-day period, and there must be 181 days during any consecutive 360-day period during
which no Payment Blockage Period is in effect.

Section 1604. Demand for Payment.

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

Section 1605. When Distribution Must Be Paid Over; Reinstatement of Senior Indebtedness.

     If a distribution is made to Noteholders that because of this Article Sixteen should not have
been made to them, the Noteholders who receive the distribution shall hold it in trust for holders
of Senior Indebtedness of the applicable Subsidiary Guarantor and pay it over to them or their
Representatives as their interests may appear.

     To the extent any payment of or distribution in respect of Senior Indebtedness (whether by or
on behalf of any Subsidiary Guarantor as proceeds of security or enforcement of any right of setoff
or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any
receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person under any
bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then if such payment or
distribution is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating
trustee, agent or other similar Person, the Senior Indebtedness or part thereof originally intended
to be satisfied shall be deemed to be reinstated and outstanding as if such payment had not
occurred.

Section 1606. Subrogation.

     After all Senior Indebtedness of a Subsidiary Guarantor is paid in full and until the 65⁄8%
Notes are paid in full, Noteholders shall be subrogated to the rights of holders of such Senior
Indebtedness to receive distributions applicable to Senior Indebtedness of such Subsidiary
Guarantor. A distribution made under this Article Sixteen to holders of such Senior Indebtedness
which otherwise would have been made to Noteholders is not, as between the relevant Subsidiary
Guarantor and Noteholders, a payment by such Subsidiary Guarantor on such Senior Indebtedness.

Section 1607. Relative Rights.

     This Article Sixteen defines the relative rights of Noteholders and holders of Senior
Indebtedness of a Subsidiary Guarantor. Nothing in this Indenture shall:

67

 

     (1)       impair, as between a Subsidiary Guarantor and Noteholders, the obligation of such
Subsidiary Guarantor, which is absolute and unconditional, to pay its Subsidiary Guaranty to the
extent set forth in Article Fifteen; or

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

Section 1608. Subordination May Not Be Impaired by Company.

     No right of any present or future holders of any Senior Indebtedness of any Subsidiary
Guarantor to enforce subordination as provided in this Indenture will at any time in any way be
prejudiced or impaired by noncompliance by such Subsidiary Guarantor with the terms of this
Indenture, regardless of any knowledge thereof that any such Holder of Senior Indebtedness may have
or otherwise be charged with.

Section 1609. Rights of Trustee and Paying Agent; Rights of Holders of Senior
Indebtedness.

     Notwithstanding Section 1603, the Trustee or Paying Agent shall continue to make payments on
any Subsidiary Guaranty and shall not be charged with knowledge of the existence of facts that
under this Article Sixteen would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Trustee receives written
notice satisfactory to it that such payments are prohibited by this Article Sixteen. The Company,
the relevant Subsidiary Guarantor, the Security Registrar, the Paying Agent, a Representative or a
holder of Senior Indebtedness of such Subsidiary Guarantor shall be entitled to give the notice;
provided, however, that, if an issue of Senior Indebtedness of any Subsidiary Guarantor has a
Representative, only the Representative shall be entitled to give the notice.

     The Trustee in its individual or any other capacity shall be entitled to hold Senior
Indebtedness of any Subsidiary Guarantor with the same rights it would have if it were not the
Trustee. The Security Registrar and the Paying Agent may do the same with like rights. The Trustee
shall be entitled to all the rights set forth in this Article Sixteen with respect to any Senior
Indebtedness of any Subsidiary Guarantor which may at any time be held by it, to the same extent as
any other holder of such Senior Indebtedness; and nothing in Article Six shall deprive the Trustee
of any of its rights as such holder. Nothing in this Article Sixteen shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 607.

     The holders of Senior Indebtedness may, at any time and from time to time subject to the terms
of such Senior Indebtedness, without the consent of or notice to the Trustee or the Noteholders,
without incurring responsibility to the Noteholders and without impairing or releasing the
subordination provided in this Indenture or the obligations hereunder of the Noteholders to the
holders of Senior Indebtedness, do any one or more of the following:

     (1)       change the manner, place or terms of payment or extend the time of payment of, or renew or
alter, Senior Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding or secured;

68

 

     (2)       sell, exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Indebtedness;

     (3)       release any Person liable in any manner for the collection of Senior Indebtedness; and

     (4)       exercise or refrain from exercising any rights against any Subsidiary Guarantor and any
other Person.

Section 1610. Distribution or Notice to Representative.

     Whenever any Person is to make a distribution or give a notice to holders of Senior
Indebtedness of any Subsidiary Guarantor, such Person shall be entitled to make such distribution
or give such notice to their Representative (if any).

Section 1611. Article Sixteen Not to Prevent Events of Default or Limit Right to Demand
Payment.

     The failure to make a payment pursuant to a Subsidiary Guaranty by reason of any provision in
this Article Sixteen shall not be construed as preventing the occurrence of a Default. Nothing in
this Article Sixteen shall have any effect on the right of the Noteholders or the Trustee to make a
demand for payment on any Subsidiary Guarantor pursuant to its Subsidiary Guaranty.

Section 1612. Trust Moneys Not Subordinated.

     Notwithstanding anything contained herein to the contrary, payments from any money or the
proceeds of U.S. Government Obligations held in trust under Article Four or Thirteen by the Trustee
for the payment of principal of and interest on the 65⁄8% Notes shall not be subordinated to the
prior payment of any Senior Indebtedness of any Subsidiary Guarantor or subject to the restrictions
set forth in this Article Sixteen, and none of the Noteholders shall be obligated to pay over any
such amount to any Subsidiary Guarantor or any holder of Senior Indebtedness of any Subsidiary
Guarantor or any other creditor of any Subsidiary Guarantor.

Section 1613. Trustee Entitled to Rely.

     Upon any payment or distribution pursuant to this Article Sixteen, the Trustee and the
Noteholders shall be entitled to rely (1) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 1602 are pending, (2)
upon a certificate of the liquidating trustee or agent or other Person making such payment or
distribution to the Trustee or to the Noteholders or (3) upon the Representatives for the holders
of Senior Indebtedness of any Subsidiary Guarantor for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of such Senior Indebtedness
and other indebtedness of such Subsidiary Guarantor, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this
Article Sixteen. In the event that the Trustee determines, in good faith, that evidence is required
with respect to the right of any Person as a holder of Senior Indebtedness of any Subsidiary
Guarantor to participate in any payment or distribution pursuant to this Article Sixteen, the

69

 

Trustee shall be entitled to request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Indebtedness of such Subsidiary Guarantor
held by such Person, the extent to which such Person is entitled to participate in such payment or
distribution and other facts pertinent to the rights of such Person under this Article Sixteen,
and, if such evidence is not furnished, the Trustee shall be entitled to defer any payment to such
Person pending judicial determination as to the right of such Person to receive such payment. The
provisions of Sections 601 and 603 shall be applicable to all actions or omissions of actions by
the Trustee pursuant to this Article Sixteen.

Section 1614. Trustee to Effectuate Subordination.

     Each Noteholder by accepting an 65⁄8% Note authorizes and directs the Trustee on its behalf to
take such action as may be necessary or appropriate to effectuate the subordination provided in
this Article Sixteen and appoints the Trustee as attorney-in-fact for any and all such purposes.

Section 1615. Trustee Not Fiduciary for Holders of Senior Indebtedness of Subsidiary
Guarantor.

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

Section 1616. Reliance by Holders of Senior Indebtedness of Subsidiary Guarantors on
Subordination Provisions.

     Each Noteholder by accepting an 65⁄8% Note acknowledges and agrees that the foregoing
subordination provisions are, and are intended to be, an inducement and a consideration to each
holder of any Senior Indebtedness of any Subsidiary Guarantor, whether such Senior Indebtedness was
created or acquired before or after the issuance of the 65⁄8% Notes, to acquire and continue to hold,
or to continue to hold, such Senior Indebtedness and such holder of Senior Indebtedness shall be
deemed conclusively to have relied on such subordination provisions in acquiring and continuing to
hold, or in continuing to hold, such Senior Indebtedness.

     SECTION 11.       Governing Law.

     This Third Supplemental Indenture and the 65⁄8% Notes shall be governed by and construed in
accordance with the laws of the State of New York.

     SECTION 12.       Counterparts.

     This Third Supplemental Indenture may be executed in any number of counterparts, each of which
shall be an original but such counterparts shall together constitute but one and the same
instrument.

70

 

     SECTION 13.       Supplemental Indenture Controls.

     In the event there is any conflict or inconsistency between the Original Indenture and this
Third Supplemental Indenture, the provisions of this Third Supplemental Indenture shall control.

71

[FORM OF THE REVERSE OF 65⁄8% NOTE]

NEWFIELD EXPLORATION COMPANY

65⁄8% Senior Subordinated Note due 2016

     1.       Indenture; Limitations.

     The Company issued the 65⁄8% Notes under the Subordinated Indenture dated as of December 10,
2001 (the “Original Indenture”), as supplemented and amended by the Third Supplemental Indenture
dated as of April 3, 2006 (the Original Indenture as so supplemented and amended being hereinafter
referred to as the “Indenture”), between the Company and Wachovia Bank, National Association, as
trustee (the “Trustee”). Capitalized terms herein are used as defined in the Indenture unless
otherwise indicated. The terms of the 65⁄8% Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act. The 65⁄8% Notes are subject to
all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a
statement of all such terms. To the extent permitted by applicable law, in the event of any
inconsistency between the terms of this 65⁄8% Note and the terms of the Indenture, the terms of the
Indenture shall control.

     The 65⁄8% Notes are senior subordinated obligations of the Company and the aggregate principal
amount of the 65⁄8% Notes which may be issued, executed, authenticated, delivered and outstanding is
unlimited (subject to Section 1 of the Third Supplemental Indenture). The Company may, subject to
Section 1010 of the Indenture, issue Additional 65⁄8% Notes under the Indenture in either a limited
or an unlimited aggregate principal amount. This 65⁄8% Note is one of the Original 65⁄8% Notes referred
to in the Indenture issued in an aggregate principal amount of $550,000,000. Any Additional 65⁄8%
Notes may be issued as part of the same or a different series of Securities as the Original 65⁄8%
Notes, but all such 65⁄8% Notes shall be treated as a single class under the Indenture.

     2.       Principal and Interest.

     The Company will pay the principal of this 65⁄8% Note on April 15, 2016.

     The Company promises to pay interest on the principal amount of this 65⁄8% Note on each April 15
and October 15 (each an “Interest Payment Date”), as set forth below, at the rate per annum shown
above.

     Interest will be payable semiannually (to the holders of record of the 65⁄8% Notes at the close
of business on the April 1 or October 1 immediately preceding the Interest Payment Date) on each
Interest Payment Date, commencing October 15, 2006.

A-3

 

     Interest on the 65⁄8% Notes will accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from April 3, 2006, provided that, if there is no existing
Default in the payment of interest and this 65⁄8% Note is authenticated between a Regular Record Date
referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue
from such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve
30-day months.

     The Company shall pay interest on overdue principal at the rate borne by the 65⁄8% Notes plus 1%
per annum, and it shall pay interest on overdue installments of interest, to the extent lawful, at
the rate borne by the 65⁄8% Notes plus 1% per annum.

     3.       Method of Payment.

     The Company will pay interest (except Defaulted Interest) on the principal amount of the 65⁄8%
Notes as provided above on each Interest Payment Date to the persons who are Holders (as reflected
in the Security Register at the close of business on the April 1 and October 1 immediately
preceding the relevant Interest Payment Date), in each case, even if the 65⁄8% Note is canceled on
registration of transfer, registration of exchange, redemption or repurchase after such record date
and on or before the Interest Payment Date, provided that, with respect to the payment of
principal, the Company will make payment to the Holder that surrenders this 65⁄8% Note to a Paying
Agent on or after its Maturity.

     The Company will pay principal, premium, if any, and as provided above, interest in money of
the United States that at the time of payment is legal tender for payment of public and private
debts. The Company will make such payments (i) by wire transfer of immediately available funds to
any account maintained in the United States with respect to Global Securities or 65⁄8% Notes held in
certificated form with an aggregate principal amount in excess of $1,000,000 whose Holder has
requested such method of payment and provided wire transfer instructions to the Paying Agent or
(ii) by check payable in such money mailed to a Holder’s registered address with respect to any
certificated 65⁄8% Notes. If a payment date is a date other than a Business Day at a Place of
Payment, payment may be made at that place on the next succeeding day that is a Business Day and no
interest shall accrue for the intervening period.

     4.       Paying Agent and Security Registrar.

     Initially, the Trustee will act as Paying Agent and Security Registrar in relation to the 65⁄8%
Notes. The Company may change any authenticating agent, Paying Agent or Security Registrar without
notice.

A-4

 

     5.       Optional and Mandatory Redemption.

     The 65⁄8% Notes are subject to both optional and mandatory redemption, either as a whole or in
some cases in part, at the times, under the circumstances, upon the giving of prior notices to
Holders and at the Redemption Prices described in Article Eleven of the Indenture.

     6.       Subordination.

     The 65⁄8% Notes are subordinated to Senior Indebtedness of the Company. To the extent provided
in the Indenture, Senior Indebtedness of the Company must be paid before the 65⁄8% Notes may be paid.
The Company and each Holder by accepting a 65⁄8% Note agree to the subordination provisions
contained in the Indenture and authorize the Trustee to give it effect and appoint the Trustee as
attorney-in-fact for such purpose.

     7.       Repurchase upon a Change of Control.

     Upon the occurrence of a Change of Control, each Holder of 65⁄8% Notes shall have the right to
require the Company to repurchase all or any part (equal to $1,000 in principal amount or an
integral multiple thereof) of such Holder’s 65⁄8% Notes pursuant to the Change of Control Offer as
provided in, and subject to the terms of, the Indenture at a purchase price in cash equal to 101%
of the principal amount of the 65⁄8% Notes repurchased, plus accrued and unpaid interest, if any, to
the date of purchase (subject to the right of holders of record on the relevant record date to
receive interest due on the relevant Interest Payment Date).

     8.       Denominations; Transfer; Exchange.

     The 65⁄8% Notes are in registered form without coupons in denominations of $1,000 of principal
amount and multiples of $1,000 in excess thereof. A Holder may register the transfer of or exchange
65⁄8% Notes in accordance with the Indenture. The Security Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or
other governmental charges imposed on the transaction. The Security Registrar need not register
the transfer of or exchange any 65⁄8% Notes selected or called for redemption (except in the case of
a 65⁄8% Note redeemed in part, the portion of the 65⁄8% Note not to be redeemed). Also, it need not
register the transfer or exchange of any 65⁄8% Notes for a period of 15 days before the day of the
mailing of a notice of redemption of 65⁄8% Notes selected for redemption.

     9.       Persons Deemed Owners.

     A Holder shall be treated as the owner of a 65⁄8% Note for all purposes.

     10.       Unclaimed Money.

A-5

 

     If money for the payment of principal, premium, if any, or interest remains unclaimed for two
years, the Trustee and the Paying Agent will pay the money back to the Company at its written
request, unless an abandoned property law provides otherwise. After that, Holders entitled to the
money must look to the Company for payment, and all liability of the Trustee and the Paying Agent
with respect to such money shall cease.

     11.       Discharge Prior to Redemption or Maturity.

     Subject to certain conditions, if the Company deposits with the Trustee money or U.S.
Government Obligations sufficient to pay the then outstanding principal of, premium, if any, and
accrued interest on the 65⁄8% Notes to redemption or Stated Maturity, as applicable, the Company and
the Subsidiary Guarantors, if any, may terminate some of or all of their obligations under the
Indenture and the 65⁄8% Notes, all as provided in Articles Four and Thirteen of the Indenture.

     12.       Amendment; Supplement; Waiver.

     Subject to certain exceptions, the Indenture or the 65⁄8% Notes may be amended or supplemented
with the consent of the Holders of at least a majority in principal amount of the 65⁄8% Notes then
Outstanding, and any existing Default or compliance with any provision may be waived with the
consent of the Holders of at least a majority in principal amount of the 65⁄8% Notes then
Outstanding. Without notice to or the consent of any Holder, the parties thereto may amend or
supplement the Indenture or the 65⁄8% Notes to, among other things, cure any ambiguity, defect or
inconsistency and make any other change that does not adversely affect the interests of any Holder
in any material respect.

     13.       Restrictive Covenants.

     The Indenture imposes certain limitations on the ability of the Company and its Restricted
Subsidiaries, among other things, to Incur additional Indebtedness, make Restricted Payments, use
the proceeds from Asset Dispositions, suffer to exist restrictions on the ability of Restricted
Subsidiaries to make certain payments to the Company, engage in transactions with Affiliates,
suffer to exist or incur Liens, Incur layered Indebtedness or merge, consolidate or transfer
substantially all of their assets. The Company is also required to cause each of its Restricted
Subsidiaries that Guarantees or secures other Indebtedness of the Company to, at the same time,
Guarantee payment of the 65⁄8% Notes on the terms provided in Article Fifteen of the Indenture.
Within 120 days after the end of each fiscal year, the Company shall deliver to the Trustee an
Officers’ Certificate stating whether or not the signers know of any Default or Event of Default
under such restrictive covenants.

     14.       Successor Persons.

A-6

 

     Subject to certain exceptions, when a successor Person assumes all the obligations of its
predecessor under the 65⁄8% Notes and the Indenture, the predecessor Person will be released from
those obligations.

     15.       Defaults and Remedies.

     The following are summaries of Events of Default under the Indenture with respect to the 65⁄8%
Notes:

     (a)       failure to pay any interest on the 65⁄8% Notes when due, continued for 30 days;

     (b)       failure to pay principal of (or premium, if any, on) the 65⁄8% Notes when due;

     (c)       failure to comply with Article Eight of the Indenture;

     (d)       failure to perform any other covenant of the Company or any Subsidiary Guarantor in
the Indenture, continued for 90 days after written notice to the Company from the Trustee or
the Holders of at least 25% in aggregate principal amount of the Outstanding 65⁄8% Notes;

     (e)       a default by the Company or any Restricted Subsidiary under any Indebtedness in an
aggregate principal amount greater than $10.0 million (other than Non-recourse Purchase
Money Indebtedness) that results in acceleration of the maturity of such Indebtedness, or
failure to pay any such Indebtedness at maturity within any applicable grace period, if such
Indebtedness is not repaid or such acceleration is not rescinded within 10 days beyond the
applicable grace period or the acceleration as provided in the Indenture;

     (f)       one or more judgments or decrees by a court of competent jurisdiction are entered
against the Company, a Subsidiary Guarantor or any Significant Subsidiary in an uninsured
or unindemnified aggregate amount outstanding at any time in excess of $10.0 million and
such judgments or decrees are not discharged, waived, stayed, satisfied or bonded for a
period of 60 consecutive days;

     (g)       certain events of bankruptcy, insolvency or reorganization with respect to the
Company, a Subsidiary Guarantor or any Significant Subsidiary; or

     (h)       a Subsidiary Guaranty ceases to be in full force and effect (other than in
accordance with the terms of such Subsidiary Guaranty) for five days after notice as
provided in the Indenture or a Subsidiary Guarantor denies or disaffirms its obligations
under its Subsidiary Guaranty.

A-7

 

     The Indenture provides that if an Event of Default (other than an Event of Default described
in clause (g) above) with respect to the 65⁄8% Notes at the time Outstanding shall occur and be
continuing, either the Trustee or the Holders of at least 25% in aggregate principal amount of the
Outstanding 65⁄8% Notes by notice as provided in the Indenture may declare the principal amount of
the 65⁄8% Notes, together with accrued and unpaid interest thereon, to be due and payable
immediately. If an Event of Default described in clause (g) above with respect to the 65⁄8% Notes at
the time Outstanding shall occur, the principal amount of all the 65⁄8% Notes, together with accrued
and unpaid interest thereon, will ipso facto, and without any action by the Trustee or any Holder,
become immediately due and payable. After any such acceleration, but before a judgment or decree
based on acceleration, the Holders of at least a majority in aggregate principal amount of the
Outstanding 65⁄8% Notes may, under certain circumstances, rescind and annul such acceleration if all
Events of Default, other than the nonpayment of accelerated principal, have been cured or waived as
provided in the Indenture.

     16.       Trustee Dealings with the Company or the Subsidiary Guarantors.

     The Trustee under the Indenture, in its individual or any other capacity, may make loans to,
accept deposits from and perform services for the Subsidiary Guarantors, if any, or the Company or
their Affiliates and may otherwise deal with the Subsidiary Guarantors, if any, or the Company or
their Affiliates as if it were not the Trustee.

     17.       No Recourse Against Others.

     No incorporator or any past, present or future partner, stockholder, other equity holder,
officer, director, employee or controlling Person as such, of the Company or any Subsidiary
Guarantor shall have any liability for any obligations of the Company or any Subsidiary Guarantor
under the 65⁄8% Notes or the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation. Each Holder by accepting a 65⁄8% Note expressly waives and releases
all such liability. The waiver and release are a condition of, and part of the consideration for
the issuance of the 65⁄8% Notes.

     18.       Authentication.

     This 65⁄8% Note shall not be valid until the Trustee or authenticating agent signs the
certificate of authentication on the other side of this 65⁄8% Note.

     19.       Abbreviations.

     Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM
(= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian) and U/G/M/A (= Uniform Gifts to
Minors Act).

     20.       Governing Law.

     THIS 65⁄8% NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK.

     21.       CUSIP Numbers.

     Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification
Procedures, the Company has caused CUSIP numbers to be printed on the 65⁄8% Notes and has directed
the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders. No

Indenture. Requests may be made to Newfield Exploration Company, 363 N. Sam Houston Parkway E.,

71/4% Senior Notes due 2018

     KB Home, a Delaware corporation (hereinafter called the “Company”, which term includes
any successor corporation under the Indenture referred to below), for value received, hereby
promises to pay to Cede & Co., or registered assigns, the principal sum of THREE HUNDRED MILLION
DOLLARS ($300,000,000) or such other principal amount as is set forth on Schedule A hereto on June
15, 2018, and to pay interest thereon from April 3, 2006, or from the most recent date to which
interest has been paid or duly provided for, semiannually in arrears on June 15 and December 15 of
each year (each, an “Interest Payment Date”), commencing December 15, 2006, and at Maturity, at the
rate of 71/4% per annum, until the principal hereof is paid or duly made available for payment.
Interest on this Note shall be calculated on the basis of a 360-day year consisting of twelve
30-day months. The interest so payable and punctually paid or duly provided for on any Interest
Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Note (or
one or more Predecessor Securities) is registered at the close of business on the Regular Record
Date for such interest, which shall be the June 1 or December 1 (whether or not a Business Day), as
the case may be, immediately preceding such Interest Payment Date. Any such interest which is
payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall
forthwith cease to be payable to the Person who was the Holder hereof on the relevant Regular
Record Date by virtue of having been such Holder, and may be paid to the Person in whose name this
Note (or one or more Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof
shall be given to the Holder of this Note not less than 10 days prior to such Special Record Date,
or may be paid at any time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Notes may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in such Indenture.

     Payment of the principal of and premium, if any, and interest on this Note will be made at the
Office or Agency of the Company maintained for that purpose in the Borough of Manhattan, The City
of New York, in such coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts; provided, however, that, at the option of the
Company, interest may be paid by check mailed to the

 

address of the Person entitled thereto as such address shall appear in the Security Register
or by transfer to an account maintained by the payee with a bank located in the United States; and
provided, further, that if this Note is a global Note registered in the name of a Depository or its
nominee, then, anything in the Indenture or the Notes to the contrary notwithstanding, payments of
the principal of and premium, if any, and interest on this Note shall be made by wire transfer.

     This Note is one of a duly authorized issue of Securities of the Company (herein called the
“Notes”) issued and to be issued in one or more series under an Indenture dated as of January 28,
2004 (the “Original Indenture”), as amended and supplemented by the First Supplemental Indenture
dated as of January 28, 2004 (the “First Supplemental Indenture”), and by the Second Supplemental
Indenture dated as of June 30, 2004 (the “Second Supplemental Indenture”; the Original Indenture,
as amended and supplemented by the First Supplemental Indenture and the Second Supplemental
Indenture and all other indentures supplemental thereto, is herein called the “Indenture”), each
among the Company, the Guarantors and SunTrust Bank, as trustee (herein called the “Trustee”, which
term includes any successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the
Holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and
delivered. This Note is one of the series designated on the face hereof, initially limited
(subject to exceptions provided in the Indenture and subject to the right of the Company to reopen
such series for issuance of additional Securities of such series upon the terms and subject to the
conditions specified in the Indenture) in aggregate principal amount to $300,000,000.

     Payments of principal of and premium, if any, and interest on the Notes are fully, irrevocably
and unconditionally guaranteed, jointly and severally, by the Guarantors on the terms and subject
to the limitations set forth in the Indenture. A Guarantor may be released from its obligations
under the Indenture and those obligations may be reinstated, all on the terms and subject to the
conditions set forth in the Indenture.

     The Notes may be redeemed, in whole at any time or from time to time in part, at the Company’s
option on any date (each, a “Redemption Date”) at a Redemption Price equal to the greater of: (a)
100% of the principal amount of the Notes to be redeemed, and (b) the sum of the present values of
the remaining scheduled payments of principal and interest on the Notes to be redeemed (exclusive
of interest accrued to the applicable Redemption Date) discounted to such Redemption Date on a
semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate
plus 35 basis points, plus, in the case of both clause (a) and (b) above, accrued and unpaid
interest on the principal amount of the Notes being redeemed to such Redemption Date.
Notwithstanding the foregoing, installments of interest on Notes whose Stated Maturity is on or
prior to the relevant Redemption Date will be payable to the Holders of such Notes (or one or more
Predecessor Securities) registered as such at the close of business on the relevant Regular Record
Date according to their terms and the provisions of the Indenture.

     As used in this Note, the following terms have the meanings set forth below:

     “Treasury Rate” means, with respect to any Redemption Date for the Notes:

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

2

 

The Treasury Rate shall be calculated on the third Business Day preceding the applicable Redemption
Date. As used in the immediately preceding sentence and in the definition of “Reference Treasury
Dealer Quotations” below, the term “Business Day” means each Monday, Tuesday, Wednesday, Thursday
and Friday which is not a day on which banking institutions in The City of New York are authorized
or obligated by law, regulation or executive order to close.

     “Comparable Treasury Issue” means, with respect to any Redemption Date for the Notes, the
United States Treasury security selected by the Independent Investment Banker as having a maturity
comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new issues of corporate
debt securities of comparable maturity to the remaining term of the Notes to be redeemed.

     “Independent Investment Banker” means, with respect to any Redemption Date for the Notes, Banc
of America Securities LLC and its successors or, if such firm or any successor to such firm, as the
case may be, is unwilling or unable to select the Comparable Treasury Issue, an independent
investment banking institution of national standing appointed by the Trustee after consultation
with the Company.

     “Comparable Treasury Price” means, with respect to any Redemption Date for the Notes:

	 	(a)	 	the average of four Reference Treasury Dealer Quotations for such Redemption
Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations,
or
	 
	 	(b)	 	if the Trustee obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such quotations.

     “Reference Treasury Dealer” means Banc of America Securities LLC and its successors
(provided, however, that if such firm or any such successor, as the case may be, shall cease to be
a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the
Trustee, after consultation with the Company, will substitute therefor another Primary Treasury
Dealer) and three other Primary Treasury Dealers selected by the Trustee after consultation with
the Company.

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

     “Final Maturity Date” means June 15, 2018.

     Notice of any redemption by the Company will be mailed at least 30 days but not more than 60
days before any Redemption Date to each Holder of Notes to be redeemed. If less than all the Notes
are to be redeemed at the option of the Company, the Trustee will select, in such manner as it
deems fair and appropriate, the Notes (or portions thereof) to be redeemed. Unless the Company
defaults in payment of the Redemption Price (including, without limitation, interest, if any,
accrued to the applicable Redemption Date), on and after the applicable Redemption Date interest
will cease to accrue on the Notes or portions thereof called for redemption on such Redemption
Date.

     If an Event of Default with respect to the Notes shall occur and be continuing, the principal
of and accrued and unpaid interest on the Notes may be declared due and payable in the manner and
with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the Guarantors and the rights of
the Holders of the Securities of each series issued under the Indenture at any time by the Company,
the Guarantors and the Trustee with the consent of the Holders of not less than a majority in
aggregate principal amount of the Securities at the time

Outstanding of each series affected thereby. The Indenture also contains provisions
permitting the Holders of specified percentages in aggregate principal amount of the Securities of
any series at the time Outstanding, on behalf of the Holders of all Securities of such series, to
waive compliance by the Company and the Guarantors with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such consent or waiver by
the Holder of this Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Note and of any Notes issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon
this Note.

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

     As provided in the Indenture and subject to certain limitations set forth therein, the
transfer of this Note may be registered on the Security Register upon surrender of this Note for
registration of transfer at the Office or Agency of the Company maintained for the purpose in any
place where the principal of and interest on this Note are payable, duly endorsed, or accompanied
by a written instrument of transfer in form satisfactory to the Company and the Security Registrar
duly executed by the Holder hereof or by his attorney duly authorized in writing, and thereupon one
or more new Notes, of authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

     The Notes are issuable only in fully registered form without coupons in the denominations of
$1,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and
subject to certain limitations set forth therein, the Notes are exchangeable for a like aggregate
principal amount of Notes of authorized denominations as requested by the Holders surrendering the
same.

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

     Prior to due presentment of this Note for registration of transfer, the Company, the
Guarantors, the Trustee and any agent of the Company, any Guarantor or the Trustee may treat the
Person in whose name this Note is registered as the owner hereof for all purposes, whether or not
this Note shall be overdue, and none of the Company, the Guarantors or the Trustee nor any such
agent shall be affected by notice to the contrary.

     The Indenture contains provisions whereby (i) the Company and the Guarantors may be discharged
from their obligations with respect to the Notes (subject to certain exceptions) or (ii) the
Company may be released from its obligations under specified covenants and agreements in the
Indenture, in each case if the Company irrevocably deposits with the Trustee money and/or
Government Obligations sufficient to pay and discharge the entire indebtedness on all Notes, and
satisfies certain other conditions, all as more fully provided in the Indenture. In addition, the
Indenture shall cease to be of further effect (subject to certain exceptions) with respect to the
Notes when (1) either (A) all Notes previously authenticated and delivered have been delivered
(subject to certain exceptions) to the Trustee for cancellation, or (B) all Notes (i) have become
due and payable or (ii) will become due and payable at their Stated Maturity within one year or
(iii) are to be called for redemption within one year and, in the case of (i), (ii) or (iii) above,
the Company has irrevocably deposited with the Trustee money in an amount sufficient to pay and
discharge the entire indebtedness on all such Notes not theretofore delivered to the Trustee for
cancellation in respect of principal, premium, if any, and interest to the date of such deposit (if
such Notes have become due and payable) or to the Stated Maturity or Redemption Date thereof, as
the case may be, and (2) the Company satisfies certain other conditions, all as more fully provided
in the Indenture.

     This Note shall be governed by and construed in accordance with the laws of the State of New
York.

     All terms used in this Note which are defined in the Indenture and not defined herein shall
have the meanings assigned to them in the Indenture.

     Unless the certificate of authentication hereon has been executed by or on behalf of the
Trustee under the

Indenture by the manual signature of one of its authorized signatories, this Note shall not be
entitled to any benefits under the Indenture (including, without limitation, the Guarantees) or be
valid or obligatory for any purpose.
