THIS INDENTURE WITNESSETH

     For and in consideration of the premises and the purchase of the Notes by the Holders thereof,
the parties hereto covenant and agree, for the equal and proportionate benefit of all Holders, as
follows:

     Section 1.01. Definitions.

     “Acquired Debt” means
Indebtedness of a Person (1) existing at the time such Person becomes a
Restricted Subsidiary or (2) assumed in connection with 

1

 

the acquisition of assets from such Person, in each case, other than Indebtedness
incurred in connection with, or in contemplation of, such Person becoming a Restricted
Subsidiary or such acquisition, as the case may be. Acquired Debt shall be deemed to be incurred
on the date of the related acquisition of assets from any Person or the date the acquired Person
becomes a Restricted Subsidiary, as the case may be.

     “Additional Assets” means (i) any assets or property (other than cash, Cash Equivalents or
securities) used in the Oil and Gas Business or any business ancillary thereto, (ii) Investments in
any other Person engaged in the Oil and Gas Business or any business ancillary thereto (including
the acquisition from third parties of Capital Stock of such Person) as a result of which such other
Person becomes a Restricted Subsidiary, (iii) the acquisition from third parties of Capital Stock
of a Restricted Subsidiary or (iv) Permitted Business Investments.

     “Additional Interest” means additional interest owed to the Holders pursuant to a Registration
Rights Agreement.

     “Additional Notes” means any Notes issued under this Indenture in addition to the Original
Notes, including any Exchange Notes issued in exchange for such Additional Notes, having the same

from their date of issuance.

     “Adjusted Consolidated Net Tangible Assets” means (without duplication), as of the date of
determination, the remainder of:

     (i) the sum of

     (a) discounted future net revenues from proved oil and gas reserves of the Company and its
Restricted Subsidiaries calculated in accordance with SEC guidelines before any state, federal or
foreign income taxes, as estimated in a reserve report prepared as of the end of the Company’s most
recently completed fiscal year, which reserve report is prepared or reviewed by independent
petroleum engineers as to reserves accounting for at least 80% of all such discounted future net
revenues and by the Company’s petroleum engineers with respect to any other reserves covered by
such report, as increased by, as of the date of determination, the estimated discounted future net
revenues from (1) estimated proved oil and gas reserves acquired since such year-end, which
reserves were not reflected in such year-end reserve report, and (2) estimated increases in proved
oil and gas reserves since such year-end due to exploration, development or exploitation activities
or due to changes in geological conditions or other factors which would, in accordance with
standard industry practice, cause such revisions, in each case calculated in accordance with SEC
guidelines (utilizing the prices utilized in such year-end reserve report), and decreased by, as of
the date of determination, the estimated discounted future net revenues from (3)

2

 

estimated proved oil and gas reserves reflected in such year-end report produced or disposed
of since such year-end and (4) estimated oil and gas reserves attributable to downward revisions of
estimates of proved oil and gas reserves since such year-end due to changes in geological
conditions or other factors which would, in accordance with standard industry practice, cause such
revisions, in each case calculated in accordance with SEC guidelines (utilizing the prices utilized
in such year-end reserve report); provided that, in the case of each of the determinations made
pursuant to clauses (1) through (4), such increases and decreases shall be as estimated by the
Company’s petroleum engineers, unless there is a Material Change as a result of such acquisitions,
dispositions or revisions, in which event the discounted future net revenues utilized for purposes
of this clause (i)(a) shall be confirmed in writing an independent petroleum engineer, plus

     (b) the capitalized costs that are attributable to oil and gas properties of the Company and
its Restricted Subsidiaries to which no proved oil and gas reserves are attributable, based on the
Company’s books and records as of a date no earlier than the date of the Company’s latest annual or
quarterly financial statements, plus

     (c) the Net Working Capital on a date no earlier than the date of the Company’s latest annual
or quarterly financial statements, plus

     (d) the greater of (1) the net book value on a date no earlier than the date of the Company’s
latest annual or quarterly financial statements and (2) the appraised value, as estimated by
independent appraisers, of other tangible assets (including, without duplication, Investments in
unconsolidated Restricted Subsidiaries) of the Company and its Restricted Subsidiaries, as of the
date no earlier than the date of the Company’s latest audited financial statements (provided that
the Company shall not be required to obtain such appraisal of such assets if no such appraisal has
been performed),

     minus (ii) the sum of

     (a) minority interests, plus

     (b) any net gas balancing liabilities of the Company and its Restricted Subsidiaries reflected
in the Company’s latest audited Consolidated financial statements, plus

     (c) to the extent included in (i)(a) above, the discounted future net revenues, calculated in
accordance with SEC guidelines (utilizing the prices utilized in the Company’s year-end reserve
report), attributable to reserves which are required to be delivered to third parties to fully
satisfy the obligations of the Company and its Restricted Subsidiaries with respect to Volumetric
Production

3

 

Payments (determined, if applicable, using the schedules specified with respect thereto) plus

     (d) the discounted future net revenues, calculated in accordance with SEC guidelines,
attributable to reserves subject to Dollar-Denominated Production Payments which, based on the
estimates of production and price assumptions included in determining the discounted future net
revenues specified in (i)(a) above, would be necessary to fully satisfy the payment obligations of
the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments
(determined, if applicable, using 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, “Adjusted Consolidated Net Tangible Assets” will
continue to be calculated as if the Company were still using the full cost method of accounting.

     “Adjusted Treasury Rate” means, with respect to any redemption date, the sum of (a) the yield
to maturity at the time of computation of United States Treasury securities with a constant
maturity (as compiled and published in the most recent Federal
Reserve Statistical Release H. 15
(519) which has become publicly available at least two Business Days prior to the redemption date
(or, if such Statistical Release is no longer published, any publicly available source or similar
market data)) most nearly equal to the period from the redemption date to May 15, 2013; provided,
however, that if the period from the redemption date to May 15, 2013 is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield is given, the
Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a
year) from the weekly average yields of United States Treasury securities for which such yields are
given, except that if the period from the redemption date to May 15, 2013 is less than one year,
the weekly average yield on actually traded United States Treasury securities adjusted to a
constant maturity of one year shall be used, plus (b) 0.50%.

     “Affiliate” means, with respect to any specified Person: (1) any other Person directly or
indirectly controlling or controlled by or under direct or indirect common control with such
specified Person; (2) any other Person that owns, directly or indirectly, 10% or more of the Voting
Stock of such specified Person (or any of such specified Person’s direct or indirect parent’s
Voting Stock); or (3) any other Person 10% or more of the Voting Stock of which is beneficially
owned or held directly or indirectly by such specified Person. For the purposes of this
definition, “control” when used with respect to any specified Person means the power to direct the

exclusive of any accrued interest, plus (2) all required remaining scheduled interest payments due
on such Note through May 15, 2013, (but excluding accrued and unpaid interest to the redemption
date), computed using a discount rate equal to the Adjusted Treasury Rate, over (B) the principal
amount of such Note on such redemption date.

     “Asset Sale” means any sale, issuance, conveyance, transfer, lease or other disposition

for resale pursuant to Rule 144(d) under the Securities Act (or a successor provision) and

     (x) sold pursuant to an effective registration statement under the
Securities Act, pursuant to the Registration Rights Agreement or otherwise, or
(y) is validly tendered for exchange into an Exchange Note pursuant to an
Exchange Offer

the Company may instruct the Trustee to cancel the Note and issue to the Holder thereof (or to its
transferee) a new Note of like tenor and amount, registered in the name of the Holder thereof (or
its transferee), that does not bear the Restricted Legend, and the Trustee will comply with such
instruction.

37

 

     (d) By its acceptance of any Note bearing the Restricted Legend (or any beneficial interest in
such a Note), each Holder thereof and each owner of a beneficial interest therein acknowledges the
restrictions on transfer of such Note (and any such beneficial interest) set forth in this
Indenture and in the Restricted Legend and agrees that it will transfer such Note (and any such
beneficial interest) only in accordance with this Indenture and such legend.

     Section 2.02. Execution and Authentication; Exchange Notes; Additional Notes. (a) An
Officer shall execute the Notes for the Company by facsimile or manual signature in the name and on
behalf of the Company. If an Officer whose signature is on a Note no longer holds that office at
the time the Note is authenticated, the Note will still be valid.

     (b) A Note will not be valid until the Trustee manually signs the certificate of
authentication on the Note, with the signature conclusive evidence that the Note has been
authenticated under this Indenture.

     (c) At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Notes executed by the Company to the Trustee for authentication. The Trustee
will authenticate and deliver

     (i) Initial Notes for original issue in the aggregate principal amount not to exceed
$365,500,000,

     (ii) Initial Additional Notes from time to time for original issue in aggregate

are to be authenticated,

     (B) whether the Notes are to be Initial Notes, Additional Notes, or Exchange
Notes,

     (C) in the case of Initial Additional Notes, that the issuance of such Notes
does not contravene any provision of Article 4,

     (D) whether the Notes are to be issued as one or more Global Notes or

     Section 2.03. Registrar, Paying Agent and Authenticating Agent; Paying Agent to Hold Money
in Trust. (a) The Company may appoint one or more Registrars and one or more Paying Agents, and
the Trustee may appoint an Authenticating Agent, in which case each reference in this Indenture to
the Trustee in respect of the obligations of the Trustee to be performed by that Agent will be
deemed to be references to the Agent. The Company may act as Registrar or (except for purposes of
Article 8) Paying Agent. In each case the Company and the Trustee will enter into an appropriate agreement with the Agent implementing the
provisions of this Indenture relating to the obligations of the Trustee to be performed by the
Agent and the related rights. The Company initially appoints the Trustee as Registrar and Paying
Agent.

     (b) The Company will require each Paying Agent other than the Trustee to agree in writing that
the Paying Agent will hold in trust for the benefit of the Holders or the Trustee all money held by
the Paying Agent for the payment of principal of and interest on the Notes and will promptly notify
the Trustee of any default by the Company in making any such payment. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and account for any funds
disbursed, and the Trustee may at any time during the continuance of any payment default, upon
written request to a Paying Agent, require the Paying Agent to pay all money held by it to the
Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent will have no
further liability for the money so paid over to the Trustee.

     Section 2.04. Replacement Notes. If a mutilated Note is surrendered to the Trustee or if a
Holder claims that its Note has been lost, destroyed or wrongfully taken, the Company will issue
and the Trustee will authenticate a replacement Note of like terms, tenor and principal amount and
bearing a number not contemporaneously outstanding. Every replacement Note is an additional
obligation of the Company and entitled to the benefits of this Indenture. If required by the
Trustee or the Company, an indemnity must be furnished that is sufficient in the judgment of both
the Trustee and the Company to protect the Company and the Trustee from any loss they may suffer if
a Note is replaced. The Company may charge the Holder for the expenses of the Company and the
Trustee in replacing a Note. In case the mutilated, lost, destroyed or wrongfully taken Note has
become or is about to become due and payable, the Company in its discretion may pay the Note
instead of issuing a replacement Note.

39

 

     Section 2.05. Outstanding Notes. (a) Notes outstanding at any time are all Notes that have
been authenticated by the Trustee except for

     (1) Notes cancelled by the Trustee or delivered to it for cancellation;

     (2) any Note which has been replaced pursuant to Section 2.04 unless and until the
Trustee and the Company receive proof satisfactory to them that the replaced Note is held
by a “protected purchaser” (as defined in the Uniform Commercial Code as in effect in the
State of New York); and

     (3) on or after the maturity date or any redemption date or date for purchase of any
Notes pursuant to an Offer to Purchase, those Notes
payable or to be redeemed or purchased on that date for which the Trustee (or Paying
Agent, other than the Company or an Affiliate of the Company) holds money sufficient to
pay all amounts then due.

     (b) A Note does not cease to be outstanding because the Company or one of its Affiliates holds
the Note, provided that in determining whether the Holders of the requisite principal amount of the
outstanding Notes have given or taken any request, demand, authorization, direction, notice,
consent, waiver or other action hereunder, Notes owned by the Company or any Affiliate of the
Company will be disregarded and deemed not to be outstanding, (it being understood that in
determining whether the Trustee is protected in relying upon any such request, demand,
authorization, direction, notice, consent, waiver or other action, only Notes which the Trustee
knows to be so owned will be so disregarded). Notes so owned which have been pledged in good faith
may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee’s right so to act with respect to such Notes and that the pledgee is not the Company or any
Affiliate of the Company.

     Section 2.06. Temporary Notes. Until definitive Notes are ready for delivery, the Company
may prepare and the Trustee will authenticate temporary Notes. Temporary Notes will be
substantially in the form of definitive Notes but may have insertions, substitutions, omissions and
other variations determined to be appropriate by the Officer executing the temporary Notes, as
evidenced by the execution of the temporary Notes. If temporary Notes are issued, the Company
will cause definitive Notes to be prepared without unreasonable delay. After the preparation of
definitive Notes, the temporary Notes will be exchangeable for definitive Notes upon surrender of
the temporary Notes at the office or agency of the Company designated for the purpose pursuant to
Section 4.02, without charge to the Holder. Upon surrender for cancellation of any temporary
Notes the Company will execute and the Trustee will authenticate and deliver in exchange therefor a
like principal amount of definitive Notes of authorized denominations

40

 

and like terms and tenor.
Until so exchanged, the temporary Notes will be entitled to the same benefits under this Indenture
as definitive Notes.

     Section 2.07. Cancellation. The Company at any time may deliver to the Trustee for
cancellation any Notes previously authenticated and delivered hereunder which the Company may
have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes
previously authenticated hereunder which the Company has not issued and sold. Any Registrar or the
Paying Agent will forward to the Trustee any Notes surrendered to it for transfer, exchange or
payment. The Trustee will cancel all Notes surrendered for transfer, exchange, payment or
cancellation and dispose of them in accordance with its normal procedures or the written
instructions of the Company. The Company may not issue new Notes to replace Notes it has paid in
full or delivered to the Trustee for cancellation.

     Section 2.08. CUSIP and CINS Numbers. The Company in issuing the Notes may use “CUSIP” and
“CINS” numbers, and the Trustee will use CUSIP numbers or CINS numbers in notices of redemption or
exchange or in Offers to Purchase as a convenience to Holders, the notice to state that no
representation is made as to the correctness of such numbers either as printed on the Notes or as
contained in any notice of redemption or exchange or Offer to Purchase. The Company will promptly
notify the Trustee of any change in the CUSIP or CINS numbers.

     Section 2.09. Registration, Transfer and Exchange. (a) The Notes will be issued in
registered form only, without coupons, and the Company shall cause the Trustee to maintain a
register (the “Register”) of the Notes, for registering the record ownership of the Notes by the
Holders and transfers and exchanges of the Notes.

     (b) (1) Each Global Note will be registered in the name of the Depositary or its
nominee and, so long as DTC is serving as the Depositary thereof, will bear the DTC
Legend.

           (2) Each Global Note will be delivered to the Trustee as custodian for the
Depositary. Transfers of a Global Note (but not a beneficial interest therein) will be
limited to transfers thereof in whole, but not in part, to the Depositary, its successors
or their respective nominees, except (1) as set forth in Section 2.09(b)(4) and (2) if
approved by the Company in its reasonable discretion, transfers of portions thereof in the
form of Certificated Notes may be made upon request of an Agent Member (for itself or on
behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of
the Depositary in accordance with customary procedures of the Depositary and in compliance
with this Section and Section 2.10.

41

 

     (3) Agent Members will have no rights under this Indenture with respect to any Global
Note held on their behalf by the Depositary, and the Depositary may be treated by the
Company, any Guarantor, the Trustee and any agent of the Company, any Guarantor or the
Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever.
Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and
otherwise authorize any Person (including any Agent Member and any Person that holds a
beneficial interest in a Global Note through an Agent Member) to take any action which a
Holder is entitled to take under this Indenture or the Notes, and nothing herein will
impair, as between the Depositary and its Agent Members, the operation of customary
practices governing the exercise of the rights of a holder of any security.

     (4) If (x) the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for a Global Note and a successor depositary is not appointed by
the Company within 90 days of the notice or (y) an Event of Default has occurred and is
continuing and the Trustee has received a request from the Depositary, the Trustee will
promptly exchange each beneficial interest in a Global Note for one or more Certificated
Notes in authorized denominations and of like terms and tenor having an equal aggregate
principal amount registered in the name of the owner of such beneficial interest, as
identified to the Trustee by the Depositary, and thereupon such Global Note will be deemed
canceled. If such Note does not bear the Restricted Legend, then the Certificated Notes
issued in exchange therefor will not bear the Restricted Legend. If such Note bears the
Restricted Legend, then the Certificated Notes issued in exchange therefor will bear the
Restricted Legend.

     (c) Each Certificated Note will be registered in the name of the holder thereof or its
nominee.

     (d) A Holder may transfer a Note (or a beneficial interest therein) to another Person or
exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized
denomination and of like terms and tenor by presenting to the Trustee a written request therefor
stating the name of the proposed transferee or requesting such an exchange, accompanied by any
certification, opinion or other document required by Section 2.10. The Trustee will promptly
register any transfer or exchange that meets the requirements of this Section by noting the same in
the register maintained by the Trustee for the purpose; provided that

     (x) no transfer or exchange will be effective until it is registered in such register
and

42

 

     (y) the Trustee will not be required (i) to issue, register the transfer of or
exchange any Note for a period of 15 days before a selection of Notes of like terms and
tenor to be redeemed or purchased pursuant to an Offer to Purchase, (ii) to register the
transfer of or exchange any Note so selected for redemption or purchase in whole or in
part, except, in the case of a partial redemption or purchase, that portion of any Note
not being redeemed or purchased, or (iii) if a redemption or a purchase pursuant to an
Offer to Purchase is to occur after a Regular Record Date but on or before the
corresponding Interest Payment Date, to register the transfer of or exchange any Note on
or after the Regular Record Date and before the date of redemption or purchase. Prior to
the registration of any transfer, the Company, each Guarantor, the Trustee and their
agents will treat the Person in whose name the Note is registered as the owner and
Holder thereof for all purposes (whether or not the Note is overdue), and will not be
affected by notice to the contrary.

     From time to time the Company will execute and the Trustee will authenticate additional Notes
as necessary in order to permit the registration of a transfer or exchange in accordance with this
Section.

     No service charge will be imposed in connection with any transfer or exchange of any Note, but
the Company may require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith (other than a transfer tax or other similar
governmental charge payable upon exchange pursuant to subsection (b)(4)).

     (e) (1) Global Note to Global Note. If a beneficial interest in a Global Note is
transferred or exchanged for a beneficial interest in another Global Note, the Trustee
will (x) record a decrease in the principal amount of the Global Note being transferred or
exchanged equal to the principal amount of such transfer or exchange and (y) record a like
increase in the principal amount of the other Global Note. Any beneficial interest in one
Global Note that is transferred to a Person who takes delivery in the form of an interest
in another Global Note, or exchanged for an interest in another Global Note, will, upon
transfer or exchange, cease to be an interest in such Global Note and become an interest
in the other Global Note and, accordingly, will thereafter be subject to all transfer and
exchange restrictions, if any, and other procedures applicable to beneficial interests in
such other Global Note for as long as it remains such an interest.

     (2) Global Note to Certificated Note. If a beneficial interest in a Global Note is
transferred or exchanged for a Certificated Note, the Trustee will (x) record a decrease
in the principal amount of such Global Note equal to the principal amount of such transfer
or exchange and (y) deliver one or more new Certificated Notes in authorized denominations

43

 

and of like terms and tenor having an equal aggregate principal amount to the transferee
(in the case of a transfer) or the owner of such beneficial interest (in the case of an
exchange), registered in the name of such transferee or owner, as applicable.

     (3) Certificated Note to Global Note. If a Certificated Note is transferred or
exchanged for a beneficial interest in a Global Note, the Trustee will (x) cancel such
Certificated Note, (y) record an increase in the principal amount of such Global Note
equal to the principal amount of such transfer or exchange and (z) in the event that such
transfer or exchange involves less than the entire principal amount of the canceled
Certificated Note, deliver to the Holder thereof one or more new
Certificated Notes in authorized denominations and of like terms and tenor having an
aggregate principal amount equal to the untransferred or unexchanged portion of the
canceled Certificated Note, registered in the name of the Holder thereof.

     (4) Certificated Note to Certificated Note. If a Certificated Note is transferred or
exchanged for another Certificated Note, the Trustee will (x) cancel the Certificated Note
being transferred or exchanged, (y) deliver one or more new Certificated Notes in
authorized denominations and of like terms and tenor having an aggregate principal amount
equal to the principal amount of such transfer or exchange to the transferee (in the case
of a transfer) or the Holder of the canceled Certificated Note (in the case of an
exchange), registered in the name of such transferee or Holder, as applicable, and (z) if
such transfer or exchange involves less than the entire principal amount of the canceled
Certificated Note, deliver to the Holder thereof one or more Certificated Notes in
authorized denominations and of like terms and tenor having an aggregate principal amount
equal to the untransferred or unexchanged portion of the canceled Certificated Note,
registered in the name of the Holder thereof.

     Section 2.10. Restrictions
on Transfer and Exchange. (a) The transfer or exchange of any
Note (or a beneficial interest therein) may only be made in accordance with this Section and
Section 2.09 and, in the case of a Global Note (or a beneficial interest therein), the applicable
rules and procedures of the Depositary. The Trustee shall refuse to register any requested
transfer or exchange that does not comply with the preceding sentence.

     (b) Subject to paragraph (c), the transfer or exchange of any Note (or a beneficial interest
therein) of the type set forth in column A below for a Note (or a beneficial interest therein) of
the type set forth opposite in column B below may only be made in compliance with the certification
requirements (if any) described in the clause of this paragraph set forth opposite in column C

or exchange takes place after the Restricted Period and a duly completed Regulation S
Certificate is delivered to the Trustee or (ii) a Certificated Note that does not bear the
Restricted Legend is surrendered for transfer or exchange, upon transfer or exchange the

of the United States. If the requested transfer or exchange involves a beneficial

Trustee with an Officers’ Certificate to that effect, and the Company may require from any
Person requesting a transfer or exchange in reliance upon this clause (1) an opinion of
counsel and any other reasonable certifications and evidence in order to support such
certificate; or

     (2)(x) sold pursuant to an effective registration statement, pursuant to a
Registration Rights Agreement or otherwise or (y) which is validly tendered for exchange
into an Exchange Note pursuant to an Exchange Offer.

     Any Certificated Note delivered in reliance upon this paragraph will not bear the Restricted
Legend.

     (d) The Trustee will retain copies of all certificates, opinions and other documents received
in connection with the transfer or exchange of a Note (or a beneficial interest therein), and the
Company will have the right to inspect and make copies thereof at any reasonable time upon written

     Section 3.02. [Reserved].

     Section 3.03. Method and Effect of Redemption. (a) If the Company elects to redeem Notes, it
must notify the Trustee of the redemption date and the principal amount of Notes to be redeemed by
delivering an Officers’ Certificate at
least 10 days before the notice of redemption required pursuant to this Section 3.03(a) is
sent to Holders (unless a shorter period is satisfactory to the Trustee). If

46

 

fewer than all of the
Notes are being redeemed, the Officers’ Certificate must also specify a record date not less than
15 days after the date the notice of redemption is sent to Holders, and the Trustee will select the
Notes to be redeemed pro rata, by lot or by any other method the Trustee in its sole discretion
deems fair and appropriate, in denominations of $1,000 principal amount and multiples thereof. The
Trustee will notify the Company promptly of the Notes or portions of Notes to be called for
redemption. Notice of redemption must be sent by the Company or at the Company’s request, by the
Trustee in the name and at the expense of the Company, to Holders whose Notes are to be redeemed at
least 30 days but not more than 60 days before the redemption date.

     (b) The notice of redemption will identify the Notes to be redeemed and will include or state
the following:

     (1) the redemption date;

     (2) the redemption price, including the portion thereof representing any accrued
interest;

     (3) the place or places where Notes are to be surrendered for redemption;

     (4) Notes called for redemption must be so surrendered in order to collect the
redemption price;

     (5) on the redemption date the redemption price will become due and payable on Notes
called for redemption, and interest on Notes called for redemption will cease to accrue on
and after the redemption date;

     (6) if any Note is redeemed in part, on and after the redemption date, upon surrender
of such Note, new Notes of like terms and tenor equal in principal amount to the
unredeemed portion will be issued; and

     (7) if any Note contains a CUSIP or CINS number, no representation is being made as
to the correctness of the CUSIP or CINS number either as printed on the Notes or as
contained in the notice of redemption and that the Holder should rely only on the other
identification numbers printed on the Notes.

     (c) Once notice of redemption is sent to the Holders, Notes called for redemption become due
and payable at the redemption price on the redemption date, and upon surrender of the Notes called
for redemption, the Company shall redeem such Notes at the redemption price. Commencing on the
redemption date, Notes redeemed will cease to accrue interest. Upon surrender of any Note
redeemed in part, the Holder will receive a new Note of like terms and tenor equal in
principal amount to the unredeemed portion of the surrendered Note.

47

 

     Section 3.04. Offer to Purchase. (a) An “Offer to Purchase” means an offer by the Company to
purchase Notes as required by this Indenture. An Offer to Purchase must be made by written offer
(the “offer”) sent to the Holders. The Company will notify the Trustee at least 15 days (or such
shorter period as is acceptable to the Trustee) prior to sending the offer to Holders of its
obligation to make an Offer to Purchase, and the offer will be sent by the Company or, at the
Company’s request, by the Trustee in the name and at the expense of the Company.

     (b) The offer must include or state the following as to the terms of the Offer to Purchase:

     (1) the provision of this Indenture pursuant to which the Offer to Purchase is being
made;

     (2) the aggregate principal amount of the outstanding Notes offered to be purchased
by the Company pursuant to the Offer to Purchase (including, if less than 100%, the manner
by which such amount has been determined pursuant to this Indenture) (the “purchase
amount”);

     (3) the purchase price, including the portion thereof representing accrued interest;

     (4) an expiration date (the “expiration date”) not less than 30 days or more than 60
days after the date of the offer, and a settlement date for purchase (the “purchase date”)
not more than five Business Days after the expiration date;

     (5) a Holder may tender all or any portion of its Notes, subject to the requirement
that any portion of a Note tendered must be in a multiple of $1,000 principal amount;

     (6) the place or places where Notes are to be surrendered for tender pursuant to the
Offer to Purchase;

     (7) each Holder electing to tender a Note pursuant to the offer will be required to
surrender such Note at the place or places specified in the offer prior to the close of
business on the expiration date (any such Certificated Note being, if the Company or the
Trustee so requires, duly endorsed or accompanied by a duly executed written instrument of
transfer);

     (8) interest on any Note not tendered, or tendered but not purchased by the Company
pursuant to the Offer to Purchase, will continue to accrue;

48

 

     (9) on the purchase date the purchase price will become due and payable on each Note
accepted for purchase, and interest on Notes purchased will cease to accrue on and after
the purchase date;

     (10) Holders are entitled to withdraw Notes tendered by giving notice, which must be
received by the Company or the Trustee not later than the close of business on the
expiration date, setting forth the name of the Holder, the principal amount of the
tendered Notes, the certificate number of any tendered Certificated Notes and a statement
that the Holder is withdrawing all or a portion of the tender;

     (11) (i) if Notes in an aggregate principal amount less than or equal to the amount
of such Notes being purchased pursuant to the Offer to Purchase are duly tendered and not
withdrawn, the Company will purchase all such Notes, and (ii) if Notes in an aggregate
principal amount in excess of the amount of such Notes being purchased pursuant to the
Offer to Purchase are duly tendered and not withdrawn, the Company will purchase Notes
having an aggregate principal amount equal to the purchase amount on a pro rata basis,
with adjustments so that only Notes in multiples of $1,000 principal amount will be
purchased;

     (12) if any Note is purchased in part, new Notes equal in principal amount to the
unpurchased portion of the Note will be issued; and

     (13) if any Note contains a CUSIP or CINS number, no representation is being made as
to the correctness of the CUSIP or CINS number either as printed on the Notes or as
contained in the offer and that the Holder should rely only on the other identification
numbers printed on the Notes.

     (c) Prior to the purchase date, the Company will accept tendered Notes for purchase as
required by the Offer to Purchase and deliver to the Trustee all Notes so accepted together with an
Officers’ Certificate specifying which Notes have been accepted for purchase. On the purchase date
the purchase price will become due and payable on each Note accepted for purchase, and interest on
Notes purchased will cease to accrue on and after the purchase date. The Trustee will promptly
return to Holders any Notes not accepted for purchase and send to Holders new Notes of like terms
and tenor equal in principal amount to any unpurchased portion of any Notes accepted for purchase
in part.

     (d) The Company will comply with Rule 14e-1 under the Exchange Act and all other applicable
laws in making any Offer to Purchase, and the above procedures will be deemed modified as necessary
to permit such compliance.

     (e) The Company will timely repay Indebtedness or obtain consents as necessary under, or
terminate, any agreements or instruments that would

49

 

otherwise prohibit an Offer to Purchase
required to be made pursuant to this Indenture.

ARTICLE 4

Covenants

     Section 4.01. Payment of Notes. (a) The Company agrees to pay the principal of and interest
on the Notes on the dates and in the manner provided in the Notes and this Indenture. Not later
than 11:00 a.m. (New York City time) on the due date of any principal of or interest on any Notes,
or any redemption or purchase price of the Notes, the Company will deposit with the Trustee (or
Paying Agent) money in immediately available funds sufficient to pay such amounts, provided that if
the Company or any Affiliate of the Company is acting as Paying Agent, it will, on or before each
due date, segregate and hold in a separate trust fund for the benefit of the Holders a sum of money
sufficient to pay such amounts until paid to such Holders or otherwise disposed of as provided in
this Indenture. In each case the Company will promptly notify the Trustee of its compliance with
this paragraph.

     (b) An installment of principal or interest will be considered paid on the date due if the
Trustee (or Paying Agent, other than the Company or any Affiliate of the Company) holds by 11:00
a.m. (New York City time) on that date money designated for and sufficient to pay the installment.
If the Company or any Affiliate of the Company acts as Paying Agent, an installment of principal or
interest will be considered paid on the due date only if paid to the Holders.

     (c) The Company agrees to pay interest on overdue principal, and, in certain circumstances and
to the extent lawful, overdue installments of interest at the rate per annum specified in the
Notes.

     (d) Payments in respect of the Notes represented by the Global Notes are to be made by wire
transfer of immediately available funds to the accounts specified by the Holders of the Global
Notes. With respect to Certificated Notes, the Company will make all payments by wire transfer of
immediately available funds to the accounts specified by the Holders thereof or, if no such account
is specified, by mailing a check to each Holder’s registered address.

     Section 4.02. Maintenance of Office or Agency. The Company will maintain in the continental
United States, an office or agency where Notes may be
surrendered for registration of transfer or exchange or for presentation for payment and where
notices and demands to or upon the Company in respect of the Notes and this Indenture may be
served. The Company hereby initially designates the Corporate Trust Office of the Trustee as such
office of the Company. The Company will give prompt written notice to the Trustee of the location,
and any change in the location, of such office or agency. If at any time

50

 

the Company fails to
maintain any such required office or agency or fails to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or served to the Trustee.

     The Company may also from time to time designate one or more other offices or agencies where
the Notes may be surrendered or presented for any of such purposes and may from time to time
rescind such designations. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other office or agency.

     Section 4.03. Existence. The Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its existence and the existence of each of its
Restricted Subsidiaries in accordance with their respective organizational documents, and the
material rights, licenses and franchises of the Company and each Restricted Subsidiary, provided
that the Company is not required to preserve any such right, license or franchise, or the existence
of any Restricted Subsidiary, if the maintenance or preservation thereof is no longer desirable in
the conduct of the business of the Company and its Restricted Subsidiaries taken as a whole; and
provided further that this Section does not prohibit any transaction otherwise permitted by
Section 4.14 or Article 5.

     Section 4.04. Payment of Obligations. The Company will pay or discharge, and cause each of
its Restricted Subsidiaries to pay or discharge as the same shall become due and payable (i) all
material tax liabilities, assessments and governmental charges or levies upon it or its properties
or assets, unless the same are being contested in good faith by appropriate proceedings diligently
conducted and adequate reserves in accordance with GAAP are being maintained by the Company or such
Restricted Subsidiary, and (ii) all material lawful claims which, if unpaid, would by law become a
Lien upon the property of the Company or any Restricted Subsidiary.

     Section 4.05. Maintenance of Properties and Insurance. (a) The Company will cause all
properties used or useful in the conduct of its business or the business of any of its Restricted
Subsidiaries to be maintained and kept in good condition, repair and working order as in the
judgment of the Company may be necessary so that the business of the Company and its Restricted
Subsidiaries may be properly and advantageously conducted at all times; provided that nothing in
this Section prevents the Company or any Restricted Subsidiary from discontinuing the use,
operation or maintenance of any of such properties or disposing of any of them, if such
discontinuance or disposal is, in the judgment of
the Company, desirable in the conduct of the business of the Company and its Restricted
Subsidiaries taken as a whole.

     (b) The Company will maintain or cause to be maintained (at its own expense), for itself and
its Restricted Subsidiaries, insurance with financially sound and reputable insurance companies, in
such amounts, with such limitations

51

 

or deductibles, against such risks, and in such form as is
customarily maintained by companies of established repute engaged in the same or similar businesses
operating in the same or similar locations.

     Section 4.06. Limitation on Indebtedness and Disqualified Stock. (a) The Company will not,
and will not cause or permit any of its Restricted Subsidiaries to, create, issue, incur, assume,
guarantee or otherwise in any manner become directly or indirectly liable for the payment of or
otherwise incur, contingently or otherwise (collectively, “incur”), any Indebtedness (including any
Acquired Debt and the issuance of Disqualified Stock), unless such Indebtedness is incurred by the
Company or any Guarantor and, in each case, the Company’s Consolidated Fixed Charge Coverage Ratio
for the most recent four full fiscal quarters for which financial statements are available
immediately preceding the incurrence of such Indebtedness taken as one period is at least equal to
or greater than 2.25:1.

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

     (1) Indebtedness of the Company or any Guarantor (whether as borrowers or guarantors)
under one or more Credit Facilities in an aggregate principal amount at any one time

30.0% of Adjusted Consolidated Net Tangible Assets;

not otherwise referred to in this definition of “Permitted Debt;”

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

     (A) if the Company or any Guarantor is the obligor on such Indebtedness,
such Indebtedness must be expressly subordinated to the prior payment in full in
cash of all obligations
with respect to the Notes, in the case of the Company, or the Note
Guarantee, in the case of a Guarantor; and

     (B) (i) any subsequent issuance or transfer of Capital Stock that results in
any such Indebtedness being held by a Person other than the Company or a
Restricted Subsidiary thereof (other than pursuant to a Credit Facility) and (ii)
any sale or other transfer

52

 

of any such Indebtedness to a Person that is not
either the Company or a Restricted Subsidiary thereof, shall be deemed, in each
case, to constitute an incurrence of such Indebtedness by the Company or such
Restricted Subsidiary, as the case may be, that was not permitted by this clause
(4);

     (5) Guarantees by the Company or any Guarantor of any Indebtedness of the Company or
any of the Guarantors which is permitted to be incurred under this Indenture;

     (B) obligations under currency exchange contracts entered into in the
ordinary course of business; and

     (C) obligations pursuant to hedging arrangements (including, without
limitation, swaps, caps, floors, collars, options and similar agreements) entered
into in the ordinary course of business for the purpose of protecting, on a net
basis, against price risks, basis risks, or other risks encountered in the Oil
and Gas Business;

     (7) Indebtedness of the Company or any Restricted Subsidiary represented by Capital
Lease Obligations (whether or not incurred pursuant to Sale Leaseback Transactions) or
Purchase Money Obligations or other Indebtedness incurred or assumed in connection with
the acquisition or development of real or personal, movable or immovable, property in each
case incurred for the purpose of financing or refinancing all or any part of the purchase
price or cost of construction or improvement of property used in the business of the
Company, in an aggregate principal amount pursuant to this clause (7) (together with the
aggregate principal amount of any Permitted Refinancing Indebtedness in respect of
Indebtedness originally incurred pursuant to this clause (7)) not to exceed $100,000,000
outstanding at any time; provided that the
principal amount of any Indebtedness permitted under this clause (7) did not in each
case at the time of incurrence exceed the Fair Market Value, as determined by the Company
in good faith, of the acquired or constructed asset or improvement so financed;

     (8) Indebtedness of the Company or any Guarantor in connection with

53

 

     (A) one or more standby letters of credit issued for the account of the
Company or a Guarantor in the ordinary course of business and

     (B) other letters of credit, surety, bid, performance, appeal or similar
bonds, bankers’ acceptances, completion guarantees or similar instruments;
provided that, in each case contemplated by this clause (8), upon the drawing of
such letters of credit or other instrument, such obligations are reimbursed

clauses (A) and (B), such Indebtedness is not in connection with the borrowing of
money or the obtaining of advances or credit;

     (9) Indebtedness of Company or any Restricted Subsidiary with respect to obligations
relating to oil or gas balancing positions arising in the ordinary course of business;

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

     (11) Permitted Refinancing Indebtedness of the Company or any Restricted Subsidiary
issued in exchange for, or the net proceeds of which are used to renew, extend,
substitute, defease, refund, refinance or replace, any Indebtedness, including any
Disqualified Stock, incurred pursuant to Section 4.06(a) and clause (2), (3), (7), (11)
or (12) of this Section 4.06 (b);

     (12) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired
Debt in connection with a transaction meeting either one of the financial tests set forth
in Section 5.01(a)(3);

     (13) Indebtedness of the Company or any Restricted Subsidiary with respect to any
obligation arising from the honoring by a bank or other financial institution of a check,
draft or similar instrument drawn against insufficient funds in the ordinary course of
business, provided, however, that such Indebtedness is extinguished within five business
days of incurrence; and

     (14) Indebtedness of the Company or any Restricted Subsidiary in addition to that
described in clauses (1) through (13) above, and any

54

 

renewals, extensions, substitutions,
refinancings or replacements of such Indebtedness, so long as the aggregate principal
amount of all such Indebtedness shall not exceed $40,000,000 outstanding at any one time
in the aggregate.

     (c) For purposes of determining compliance with this Section, in the event that an item of
Indebtedness meets the criteria of more than one of the types of Indebtedness permitted by this
Section, the Company in its sole discretion may classify or reclassify such item of Indebtedness
and only be required to include the amount of such Indebtedness as one of such types (or to divide
such Indebtedness between two or more of such types); provided that any Indebtedness under the
Senior Credit Facility which was in existence on the Prior Issue Date (after giving effect to the
application of the net proceeds from the Prior Notes) shall be deemed to have been incurred
pursuant to clause (1) of subsection (b) above rather than subsection (a) above.

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

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

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

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

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

55

action that is a Permitted Payment (as defined below), collectively, “Restricted Payments”) (the
amount of any such Restricted Payment, if other than cash, shall be the Fair Market Value of the
assets proposed to be transferred, as determined by the board of directors of the Company, whose
determination shall be conclusive and evidenced by a board resolution), unless

     (A) immediately after giving effect to such proposed Restricted Payment on
a pro forma basis, no Default or Event of Default shall have occurred and be
continuing;

aggregate cumulative Consolidated Net Income shall be a loss, minus
100% of such loss);

property other than cash, received after March 22, 2007 by the Company

Investment constituting a Restricted Payment
(including any Investment in an Unrestricted

defeasances or other retirements and acquisitions pursuant to this clause (6) will

Subsidiary of the Company on the Issue Date, in existence at the time such Person becomes
(or became) a Restricted Subsidiary of the Company and not incurred in connection with, or
in contemplation of, such Person becoming a Restricted Subsidiary, provided that such
encumbrances and restrictions are not applicable to the Company or any Restricted
Subsidiary or the properties or assets of the Company or any Restricted Subsidiary other
than such Subsidiary which is becoming a Restricted Subsidiary;

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

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

     (5) the security documents evidencing any Liens securing obligations or Indebtedness
that limit the right of the debtor to dispose of the assets subject to such Liens;

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

     (7) asset sale agreements with respect to asset sales permitted to be made under the
provisions of Section 4.14 that limit the transfer of such assets pending the closing of

the ordinary course of business; provided, however, that such encumbrances or restrictions
do not apply to any Restricted Subsidiaries other than the applicable company,
partnership, joint venture or other entity; and provided, further, however, that such
encumbrances and restrictions do not materially impact the ability of the Company to make

clauses (1) through (11), or in this clause (12); provided that the terms and conditions
of any such encumbrances or restrictions are no more restrictive in any material

63

 

respect taken as a whole than those under or pursuant to the agreement so extended, renewed,
refinanced or replaced.

     Section 4.12. Guarantees by Restricted Subsidiaries. (a) Upon the formation or acquisition
of any new direct or indirect Restricted Subsidiary (excluding (i) any Foreign Subsidiary and (ii)
any Immaterial Subsidiary) by the Company or any Restricted Subsidiary, then such new Restricted
Subsidiary will provide a Note Guarantee within 20 days after its formation or acquisition.

     (b) A Restricted Subsidiary required to provide a Note Guarantee shall execute a Supplemental
Indenture and deliver an Opinion of Counsel to the Trustee in accordance with Article 11 of this
Indenture.

     Section 4.13. Repurchase of Notes Upon a Change of Control. (a) Not later than 30 days
following a Change of Control, the Company will make an Offer to Purchase all outstanding Notes at
a purchase price equal to 101% of the principal amount plus accrued interest to the date of
purchase (subject to the right of Holders on the relevant record date to receive interest due on
the relevant Interest Payment Date).

     (b) The Company will not be required to make an Offer to Purchase pursuant to Section 4.13(a)
if a third party makes an Offer to Purchase in the manner, at the times and otherwise in compliance
with the requirements set forth in Section 4.13(a) and Section 3.04 applicable to an Offer to
Purchase made by the Company and purchases all Notes validly tendered and not withdrawn pursuant to
such Offer to Purchase.

     Section 4.14. Limitation on Asset Sales. (a) The Company will not, and will not permit any
Restricted Subsidiary to, consummate any Asset Sale unless (i) the Company or such Restricted
Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least
equal to the Fair Market Value of the assets and property subject to such Asset Sale and (ii) at
least 75% of the aggregate consideration paid to the Company or such Restricted Subsidiary in
connection with such Asset Sale and all other Asset Sales since the Prior Issue Date, on a
cumulative basis, is in the form of cash, Cash Equivalents, Liquid Securities, Exchanged Properties
(including pursuant to asset swaps), the assumption by the purchaser of liabilities of the Company
(other than liabilities of the Company that are by their terms subordinated to the Notes) or
liabilities of
any Guarantor that made such Asset Sale (other than liabilities of a Guarantor that are by
their terms subordinated to such Guarantor’s Guarantee), in each case as a result of which the
Company and its remaining Restricted Subsidiaries are no longer liable for such liabilities, or,
solely in the case of any Asset Sale of Midstream Assets, Permitted MLP Securities.

64

 

     (b) The Net Available Cash from Asset Sales by the Company or a Restricted Subsidiary may be
applied by the Company or such Restricted Subsidiary, to the extent the Company or such Restricted
Subsidiary elects (or is required by the terms of any Pari Passu Indebtedness of the Company or a
Restricted Subsidiary), to

     (1) repay any Indebtedness of the Company or any Restricted Subsidiaries other than
Subordinated Indebtedness; or

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

     (c) Excess Proceeds of less than $20,000,000 will be carried forward and accumulated. When
accumulated Excess Proceeds equals or exceeds $20,000,000, the Company must, within 7 Business
Days, make an Offer to Purchase Notes having a principal amount equal to

     (1) accumulated Excess Proceeds, multiplied by

     (2) a fraction (x) the numerator of which is equal to the outstanding principal
amount of the Notes and (y) the denominator of which is equal to the outstanding principal
amount of the Notes and all Pari Passu Indebtedness similarly required to be repaid,
redeemed or tendered for in connection with the Asset Sale, rounded down to the nearest
$1,000.

     Any Offer to Purchase Notes pursuant to this Section 4.14(c) shall be made ratably to the
Holders of the Notes on the basis of the principal amount of the Notes then outstanding. The
purchase price for the Notes will be 100% of the principal amount plus accrued interest to the date
of purchase (subject to the right of Holders on the relevant record date to receive interest due on
the relevant Interest Payment Date). Upon completion of the Offer to Purchase, Excess Proceeds
will be reset at zero.

     Section 4.15. Limitation on Transactions with Shareholders and Affiliates.

     The Company will not, and will not cause or permit any of its Restricted Subsidiaries to,
directly or indirectly, enter into any transaction or series of related
transactions (including, without limitation, the sale, purchase, exchange or lease of assets,
property or services) with or for the benefit of any Affiliate of the Company (other than the
Company or a Restricted Subsidiary) unless such transaction or series of related transactions is
entered into in good faith and in writing and

65

 

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

     (2) with respect to any transaction or series of related transactions involving aggregate
value in excess of $20,000,000,

     (i) the Company delivers an Officers’ Certificate to the Trustee certifying that such
transaction or series of related transactions complies with clause (1) above, and

     (ii) such transaction or series of related transactions has been approved by a
majority of the Disinterested Directors of the Board of Directors of the Company, or in
the event there is only one Disinterested Director, by such Disinterested Director, or

     (3) with respect to any transaction or series of related transactions involving aggregate
value in excess of $40,000,000, the Company delivers to the Trustee a written opinion of an
investment banking firm of national standing or other recognized independent expert with experience
appraising the terms and conditions of the type of transaction or series of related transactions
for which an opinion is required stating that the transaction or series of related transactions is
fair to the Company or such Restricted Subsidiary from a financial point of view;

     provided, however, that this provision shall not apply to:

     (1) employee benefit arrangements with any officer or director of the Company, including under
any employment agreement, stock option or stock incentive plans, and customary indemnification
arrangements with officers or directors of the Company, in each case entered into in the ordinary
course of business,

     (2) the payment of reasonable and customary fees to directors of the Company or any of its
Restricted Subsidiaries who are not employees of the Company or any Affiliate,

     (3) any Permitted Investments, Restricted Payments or Permitted Payments made in compliance
with Section 4.07,

     (4) sales of Capital Stock (other than Disqualified Stock) of the Company to Affiliates of the
Company,

     (5) in the case of contracts for purchase of drilling equipment or sale of oil field service
supplies or natural gas or other operational contracts, any such contracts are entered into in the
ordinary course of business on terms substantially similar to those contained in similar contracts
entered into by the Company or any Restricted Subsidiary and third parties, or if neither the
Company nor any

66

 

Restricted Subsidiary has entered into a similar contract with a third party, that
the terms are no less favorable than those available from third parties on an arm’s-length basis,
as determined by the Board of Directors of the Company,

     (6) any customary agreements with stockholders of the Company providing for preemptive,
voting, tag-along and similar rights to certain stockholders of the Company, provided that such
agreements are approved in advance by a majority of the Disinterested Directors, and

     (7) any transactions undertaken pursuant to any contracts in existence on the Issue Date (as
in effect on such date) and any renewals, replacements or modifications of such contracts (pursuant
to new transactions or otherwise) on terms no less favorable to the Holders of the Notes than those
in effect on the Issue Date.

     Section 4.16. Line of Business. Neither the Company nor any of its Restricted Subsidiaries
will directly or indirectly engage in any line or lines of business activity other than that which
is an Oil and Gas Business, except to such extent as would not be material to the Company and its
Restricted Subsidiaries, taken as a whole.

     Section 4.17. [Reserved.]

     Section 4.18. Designation of Restricted and Unrestricted Subsidiaries. (a) The Board of
Directors of the Company may designate after the Issue Date any Subsidiary as an “Unrestricted
Subsidiary” (a “Designation”) only if:

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

     (2)

     (A) the Company would be permitted to make an Investment at the time of
Designation (assuming the effectiveness of such Designation) pursuant to Section
4.07 in an amount (the “Designation Amount”) equal to the greater of (1) the net
book value of the Company’s interest in such Subsidiary calculated in
accordance with GAAP or (2) the Fair Market Value of the Company’s interest
in such Subsidiary, or

     (B) the Designation Amount is less than $1,000;

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

67

 

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

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

     In the event of any such Designation, the Company shall be deemed, for all purposes of this
Indenture, to have made an Investment equal to the Designation Amount that constitutes a Restricted
Payment pursuant to Section 4.07.

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

     (1) provide credit support for, Guarantee or subject any of its property or assets
(other than the Capital Stock of any Unrestricted Subsidiary) to the satisfaction of, any
Indebtedness of any Unrestricted Subsidiary (including any undertaking, agreement or
instrument evidencing such Indebtedness), provided, however, that the provisions of this
clause (b)(1) shall not be deemed to prevent Permitted Investments in Unrestricted
Subsidiaries that are otherwise allowed under this Indenture, or

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

     (c) For purposes of the foregoing, the Designation of a Subsidiary of the Company as an
Unrestricted Subsidiary shall be deemed to be the Designation of all of the Subsidiaries of such
Subsidiary as Unrestricted Subsidiaries.

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

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

68

 

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

     (3) unless such redesignated Subsidiary shall not have any Indebtedness outstanding
(other than Indebtedness that would be Permitted Debt), immediately after giving effect to
such proposed Revocation, and after giving pro forma effect to the incurrence of any such
Indebtedness of such redesignated Subsidiary as if such Indebtedness was incurred on the
date of the Revocation, the Company could incur $1.00 of additional Indebtedness (other
than Permitted Debt) pursuant to Section 4.06.

     (e) All Designations and Revocations must be evidenced by a resolution of the Board of
Directors of the Company delivered to the Trustee certifying compliance with the foregoing
provisions of this covenant.

     Section 4.19. [Reserved.]

     Section 4.20. Financial Reports. (a) Whether or not the Company is subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, the Company must provide the Trustee and
Noteholders within the time periods specified in those sections with

     (1) all quarterly and annual financial information that would be required to be
contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to
file such forms, including a “Management’s Discussion and Analysis of Financial Condition
and Results of Operations” and, with respect to annual information only, a report thereon
by the Company’s certified independent accountants, and

     (2) all current reports that would be required to be filed with the SEC on Form 8-K
if the Company were required to file such reports.

     (b) Whether or not required by the SEC, the Company will, if the SEC will accept the filing,
file a copy of all of the information and reports referred to
in clauses (1) and (2) of Section 4.20(a) with the SEC for public availability within the
time periods specified in the SEC’s rules and regulations, and any such information and reports so
filed with the SEC shall be deemed to have been provided to Holders pursuant to Section 4.20(a).
The Company will make the information and reports referred to in clauses (1) and (2) of Section
4.20(a) available to securities analysts and prospective investors upon request, to the extent such
information and reports have not been filed with the SEC.

69

 

     (c) If the Company had any Unrestricted Subsidiaries during the relevant period, the Company
will provide to the Trustee and the Noteholders information sufficient to ascertain the financial
condition and results of operations of the Company and its Restricted Subsidiaries, excluding in
all respects the Unrestricted Subsidiaries, to the extent such information has not been filed with
the SEC.

     (d) For so long as any of the Notes remain outstanding and constitute “restricted securities”
under Rule 144, the Company will furnish to the Holders of the Notes and prospective investors,
upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act.

     (e) All obligors on the Notes will comply with Section 314(a) of the Trust Indenture Act.

     (f) Delivery of these reports and information to the Trustee is for informational purposes
only and the Trustee’s receipt of them will 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
exclusively on Officers’ Certificates).

     Section 4.21. Reports to Trustee. (a) The Company will deliver to the Trustee within 120
days after the end of each fiscal year a certificate from the principal executive, financial or
accounting officer of the Company stating that the officer has conducted or supervised a review of
the activities of the Company and its Restricted Subsidiaries and their performance under this
Indenture and that, based upon such review, the Company has fulfilled its obligations hereunder or,
if there has been a Default, specifying the Default and its nature and status.

     (b) The Company will deliver to the Trustee, as soon as possible and in any event within 30
days after the Company becomes aware or should reasonably become aware of the occurrence of a
Default, an Officers’ Certificate setting forth the details of the Default, and the action which
the Company proposes to take with respect thereto.

     (c) The Company will notify the Trustee when any Notes are listed on any national securities
exchange and of any delisting.

with or into any other Person or sell,

70

 

assign, convey, transfer, lease or otherwise dispose of all
or substantially all of its properties and assets to any Person or group of Persons, or permit any
of its Restricted Subsidiaries to enter into any such transaction or series of transactions, if
such transaction or series of transactions, in the aggregate, would result in a sale, assignment,
conveyance, transfer, lease or disposition of all or substantially all of the properties and assets
of the Company and its Restricted Subsidiaries on a Consolidated basis to any other Person or group
of Persons (other than the Company or a Guarantor), unless at the time and after giving effect
thereto:

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

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

     (3) immediately after giving effect to such transaction on a pro forma basis (on the
assumption that the transaction occurred on the first day of the four-quarter period for
which financial statements are available ending immediately prior to the consummation of
such transaction with the appropriate adjustments with respect to the transaction being
included in such pro forma calculation), the Company (or the Surviving Entity if the
Company is not the continuing obligor under this Indenture) (A) could
incur $1.00 of additional Indebtedness (other than Permitted Debt) under the
provisions of Section 4.06 or (B) would have a Consolidated Fixed Charge Coverage Ratio
not less than the Consolidated Fixed Charge Coverage Ratio of the Company immediately
prior to such transaction;

71

 

     (4) unless the Company is the continuing obligor under this Indenture, at the time of
the transaction, each Guarantor, if any, unless it is the other party to the transactions
described above, will have confirmed, by executing a supplement to this Indenture, that
its Note Guarantee shall apply to the Surviving Entity’s obligations under this Indenture
and the Notes;

     (5) at the time of the transaction, if any of the property or assets of the Company
or any of its Restricted Subsidiaries would thereupon become subject to any Lien, the
provisions of Section 4.08 are complied with; and

     (6) at the time of the transaction, the Company or the Surviving Entity will have
delivered, or caused to be delivered, to the Trustee, an Officers’ Certificate and an
Opinion of Counsel, each to the effect that such consolidation, merger, transfer, sale,
assignment, conveyance, transfer, lease or other transaction and any supplement to this
Indenture executed and delivered in connection therewith comply with the terms of this
Indenture.

     (b) In the event of any transaction (other than a lease) described in and complying with the
conditions listed in Section 5.01(a) in which the Company is not the Surviving Entity, the
Surviving Entity shall succeed to, and be substituted for, and may exercise every right and power
of, the Company under this Indenture and the Notes, and the Company shall be discharged from all
obligations and covenants under this Indenture and the Notes.

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

     Section 5.02. Consolidation, Merger or Sale of Assets by a Guarantor. (a) Each Guarantor
will not, and the Company will not permit a Guarantor to, in a single transaction or through a
series of related transactions, (x) consolidate with or merge with or into any other Person (other
than the Company or any other Guarantor) or (y) sell, assign, convey, transfer, lease or otherwise
dispose of all or substantially all of its properties and assets to any Person or group of Persons
(other than the Company or any other Guarantor) or permit any of its Restricted Subsidiaries to
enter into any such transaction or series of transactions if such transaction or series of
transactions, in the aggregate, in the case of clause (y) would result in a sale, assignment,
conveyance, transfer, lease or disposition of all
or substantially all of the properties and assets of the Guarantor and its Restricted
Subsidiaries on a Consolidated basis to any other Person or group of Persons (other than the
Company or any Guarantor), unless at the time and after giving effect thereto:

72

 

     (1) either (A) the Guarantor or the Company will be the continuing Person in the case
of a merger involving the Guarantor or (B) the Person (if other than the Guarantor) formed
by such consolidation or into which the Guarantor is merged or the Person which acquires
by sale, assignment, conveyance, transfer, lease or disposition all or substantially all
of the properties and assets of the Guarantor and its Restricted Subsidiaries on a
Consolidated basis (the “Surviving Guarantor Entity”) expressly assumes, by executing a
supplement to this Indenture, all the obligations of such Guarantor under its Note
Guarantee;

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

     (3) at the time of the transaction such Guarantor or the Surviving Guarantor Entity
will have delivered, or caused to be delivered, to the Trustee, an Officers’ Certificate
and an Opinion of Counsel, each to the effect that such consolidation, merger, transfer,
sale, assignment, conveyance, lease or other transaction and any supplement to this
Indenture executed and delivered in connection therewith comply with this Indenture;

     provided, however, that this Section 5.02(a) shall not apply to any Guarantor whose Note
Guarantee is terminated in accordance with Section 11.09 of this Indenture.

     (b) In the event of any transaction (other than a lease) described in and complying with the
conditions listed in Section 5.02(a) in which the Guarantor is not the Surviving Guarantor Entity,
the Surviving Guarantor Entity shall succeed to, and be substituted for, and may exercise every
right and power of, such Guarantor under this Indenture, and such Guarantor shall be discharged
from all obligations and covenants under this Indenture and the Note Guarantee.

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

ARTICLE 6

Default and Remedies

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

     (1) the Company defaults in the payment of the principal of any Note when the same becomes due
and payable at Stated Maturity, upon acceleration or redemption, or otherwise (other than pursuant
to an Offer to Purchase);

73

 

     (2) the Company defaults in the payment of interest (including any Additional Interest) on any
Note when the same becomes due and payable, and the default continues for a period of 30 days;

     (3) the Company fails to make an Offer to Purchase and thereafter accept and pay for Notes
tendered when and as required pursuant to Section 4.13 or Section 4.14, or the Company or any
Guarantor fails to comply with Article 5;

     (4) the Company defaults in the performance of or breaches any other covenant or agreement of
the Company in this Indenture or under the Notes and the default or breach continues for a period
of 60 consecutive days after written notice (or 180 consecutive days after written notice in the
case of a Default pursuant to Section 4.20) to the Company by the Trustee or to the Company and the
Trustee by the Holders of 25% or more in aggregate principal amount of the Notes;

     (5) there occurs with respect to any Indebtedness of the Company, any Guarantor or any other
Significant Subsidiary having an outstanding principal amount of $50,000,000 or more in the
aggregate for all such Indebtedness of all such Persons (i) an event of default that results in
such Indebtedness (including any scheduled installment of principal with respect to such
Indebtedness) being due and payable prior to its Stated Maturity or (ii) failure to make a
principal, premium (if any) or interest payment when due and such defaulted payment is not made,
waived or extended within the applicable grace period, the result of which is to give the holder of
such Indebtedness the right to accelerate such Indebtedness;

     (6) one or more judgments, orders or decrees of any court or regulatory or administrative
agency for the payment of money in excess of $50,000,000 (determined net of any amounts covered by
insurance policies by insurers believed by the Company in good faith to be credit-worthy), either
individually or in the aggregate, shall be rendered against the Company, any Guarantor or any other
Significant Subsidiary or any of their respective properties and shall not be discharged and either
(i) any creditor shall have commenced an enforcement proceeding upon such judgment, order or decree
or (ii) there shall have been a period of 60 consecutive days during which a stay of enforcement of
such judgment or order, by reason of an appeal or otherwise, shall not be in effect;

     (7) the Company or any Significant Subsidiary institutes or consents to the institution of any
proceeding under any Debtor Relief Law with respect to it, or makes an assignment for the benefit
of creditors; or applies for or consents to the appointment of any receiver, trustee, custodian,
conservator, liquidator, rehabilitator or similar officer for it or for all or any material part of
its property; or any receiver, trustee, custodian, conservator, liquidator, rehabilitator or
similar officer is appointed without the application or consent of such Person and the appointment
continues undischarged or unstayed for 60 calendar days; or any

74

 

proceeding under any Debtor Relief
Law relating to any such Person or to all or any material part of its property is instituted
without the consent of such Person and continues undismissed or unstayed for 60 calendar days, or
an order for relief is entered in any such proceeding;

     (8) the Company or any Significant Subsidiary becomes unable or admits in writing its
inability or fails generally to pay its debts as they become due; or

     (9) any Note Guarantee ceases to be in full force and effect, other than in accordance the
terms of this Indenture, or a Guarantor denies or disaffirms its obligations under its Note
Guarantee.

     Section 6.02. Acceleration. (a) If an Event of Default occurs and is continuing under this
Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes
then outstanding, by written notice to the Company (and to the Trustee if the notice is given by
the Holders), may, and the Trustee at the request of such Holders shall, declare the principal of
and accrued interest on the Notes to be immediately due and payable. Upon a declaration of
acceleration, such principal and interest will become immediately due and payable;

provided, however, that upon the occurrence of an actual or deemed entry of an order for relief
with respect to the Company under the Bankruptcy Code of the United States, the principal of and
accrued interest on the Notes then outstanding will become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.

     (b) The Holders of a majority in aggregate principal amount of the outstanding Notes by
written notice to the Company and to the Trustee may waive all past defaults and rescind and annul
a declaration of acceleration and its consequences if

     (1) all existing Events of Default, other than the nonpayment of the principal of,
premium, if any, and interest on the Notes that have become due solely by the declaration
of acceleration, have been cured or waived, and

     (2) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction.

     Section 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee
may pursue, in its own name or as trustee of an express trust, any available remedy by proceeding
at law or in equity to collect the payment of principal of and interest on the Notes or to enforce
the performance of any provision of the Notes or this Indenture. The Trustee may maintain a

75

 

proceeding even if it does not possess any of the Notes or does not produce any of them in the
proceeding.

     Section 6.04. Waiver of Past Defaults. Except as otherwise provided in Sections 6.02, 6.07
and 9.02, the Holders of a majority in aggregate principal amount of the outstanding Notes may, by
notice to the Trustee, waive an existing Default and its consequences. Upon such waiver, the
Default will cease to exist, and any Event of Default arising therefrom will be deemed to have been
cured, but no such waiver will extend to any subsequent or other Default or impair any right
consequent thereon.

     Section 6.05. Control by Majority. The Holders of a majority in aggregate principal amount
of the outstanding Notes may direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However,
the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that may
involve the Trustee in personal liability, or that the Trustee determines in good faith may be
unduly prejudicial to the rights of Holders of Notes not joining in the giving of such direction,
and may take any other action it deems proper that is not inconsistent with any such direction
received from Holders of Notes.

     Section 6.06. Limitation on Suits. A Holder may not institute any proceeding, judicial or
otherwise, with respect to this Indenture or the Notes, or for the appointment of a receiver or
trustee, or for any other remedy under this Indenture or the Notes, unless:

     (1) the Holder has previously given to the Trustee written notice of a continuing
Event of Default;

     (2) Holders of at least 25% in aggregate principal amount of outstanding Notes have
made written request to the Trustee to institute proceedings in respect of the Event of
Default in its own name as Trustee under this Indenture;

     (3) Holders have offered to the Trustee security or indemnity reasonably satisfactory
to the Trustee against any costs, liabilities or expenses to be incurred in compliance
with such request;

     (4) the Trustee for 60 days after its receipt of such notice, request and offer of
security or indemnity has failed to institute any such proceeding; and

     (5) during such 60-day period, the Holders of a majority in aggregate principal
amount of the outstanding Notes have not given the Trustee a direction that is
inconsistent with such written request.

76

 

     Section 6.07. Rights of Holders to Receive Payment. Notwithstanding anything to the
contrary, the right of a Holder of a Note to receive payment of principal of or interest on its
Note on or after the Stated Maturities thereof, or to bring suit for the enforcement of any such
payment on or after such respective dates, may not be impaired or affected without the consent of
that Holder.

     Section 6.08. Collection Suit by Trustee. If an Event of Default in payment of principal or
interest specified in clause (1) or (2) of Section 6.01 occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust for the whole amount of
principal and accrued interest remaining unpaid, together with interest on overdue principal and,
to the extent lawful, overdue installments of interest, in each case at the rate specified in the
Notes, and such further amount as is sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel and any other amounts due the Trustee hereunder.

     Section 6.09. Trustee May File Proofs of Claim. The Trustee may file proofs of claim and
other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee hereunder) and the Holders
allowed in any judicial proceedings relating to the Company or any Guarantor or their respective
creditors or property, and is entitled and empowered to collect, receive and distribute any money,
securities or other property payable or deliverable upon conversion or exchange of the Notes or
upon any such claims. Any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by each Holder to make
such payments to the Trustee and, if the Trustee consents to the making of such payments directly
to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agent and counsel, and any other amounts
due the Trustee hereunder. Nothing in this Indenture will be deemed to empower the Trustee to
authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or
to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

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

     First: to the Trustee for all amounts due to it hereunder;

     Second: to Holders for amounts then due and unpaid for principal of and
interest on the Notes, ratably, without preference or priority of any

77

 

kind, according to
the amounts due and payable on the Notes for principal and interest; and

     Third: to the Company or as a court of competent jurisdiction may direct.

     The Trustee, upon written notice to the Company, may fix a record date and payment date for
any payment to Holders pursuant to this Section.

     Section 6.11. Restoration of Rights and Remedies. If the Trustee or any Holder has
instituted a proceeding to enforce any right or remedy under this Indenture and the proceeding has
been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or
to the Holder, then, subject to any determination in the proceeding, the Company, any Guarantors,
the Trustee and the Holders will be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Company, any Guarantors, the Trustee and
the Holders will continue as though no such proceeding had been instituted.

     Section 6.12. Undertaking for Costs. In any suit for the enforcement of any right or remedy
under this Indenture or in any suit against the Trustee for any action taken or omitted by it as
Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an
undertaking to pay the costs of the suit, and the court may assess reasonable costs, including
reasonable attorneys fees, against any party litigant (other than the Trustee) in the suit having
due regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section does not apply to a suit by a Holder to enforce payment of principal of or interest on any
Note on the respective due dates, or a suit by Holders of more than 10% in aggregate principal
amount of the outstanding Notes.

     Section 6.13. Rights and Remedies Cumulative. No right or remedy conferred or reserved to
the Trustee or to the Holders under this Indenture is intended to be exclusive of any other right
or remedy, and all such rights and remedies are, to the extent permitted by law, cumulative and in
addition to every other right and remedy hereunder or now or hereafter existing at law or in equity
or otherwise. The assertion or exercise of any right or remedy hereunder, or otherwise, will not
prevent the concurrent assertion or exercise of any other right or remedy.

     Section 6.14. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any
Holder to exercise any right or remedy accruing upon any Event of Default will impair any such
right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

78

 

     Section 6.15. Waiver of Stay, Extension or Usury Laws. The Company and each Guarantor
covenants, to the extent that it may lawfully do so, that it will not at any time insist upon, or
plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension
law or any usury law or other law that would prohibit or forgive the Company or the Guarantor from
paying all or any portion of the principal of, or interest on, the Notes as contemplated herein,
wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the
performance of this Indenture. The Company and each Guarantor hereby expressly waives, to the
extent that it may lawfully do so, all benefit or advantage of any such law and covenants that it
will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will
suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 7

The Trustee

     Section 7.01. General. (a) The duties and responsibilities of the Trustee are as provided by
the Trust Indenture Act and as set forth herein. Whether or not expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee is subject to this Article.

     (b) Except during the continuance of an Event of Default, the Trustee need perform only those
duties that are specifically set forth in this Indenture and no others, and no implied covenants or
obligations will be read into this Indenture against the Trustee. In case an Event of Default has
occurred and is continuing, the Trustee shall exercise those rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

     (c) No provision of this Indenture shall be construed to relieve the Trustee from liability
for its own negligent action, its own negligent failure to act or its own willful misconduct.

     Section 7.02. Certain Rights of Trustee. Subject to Trust Indenture Act Sections 315(a)
through (d):

     (1) In the absence of bad faith on its part, the Trustee may rely, and will be
protected in acting or refraining from acting, upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, other evidence of indebtedness or other paper or document believed by it
to be genuine and to have been signed or presented by the proper Person. The Trustee need
not investigate any fact or matter stated in the document, but, in the case

79

 

of any document which is specifically required to be furnished to the Trustee pursuant to any
provision hereof, the Trustee shall examine the document to determine whether it conforms
to the requirements of this Indenture (but need not confirm or investigate the accuracy of
mathematical calculations or other facts stated therein). The Trustee, in its discretion,
may make further inquiry or investigation into such facts or matters as it sees fit.

     (2) Before the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel conforming to Section 12.05 and the Trustee will not
be liable for any action it takes or omits to take in good faith in reliance on the
certificate or opinion.

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

     (4) The Trustee will be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders, unless
such Holders have offered to the Trustee reasonable security or indemnity against the
costs, expenses and liabilities that might be incurred by it in compliance with such
request or direction.

     (5) The Trustee will not be liable for any action it takes or omits to take in good
faith that it believes to be authorized or within its rights or powers or for any action
it takes or omits to take in accordance with the direction of the Holders in accordance
with Section 6.05 relating to the time, method and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred upon the
Trustee, under this Indenture.

     (6) The Trustee may consult with counsel, and the written advice of such counsel or
any Opinion of Counsel will be full and complete authorization and protection in respect
of any action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon.

     (7) No provision of this Indenture will require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in
the performance of its duties hereunder, or in the exercise of its rights or powers,
unless it is offered reasonable security or indemnity against any loss, liability or
expense.

     Section 7.03. Individual Rights of Trustee. The Trustee, in its individual or any other
capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or its
Affiliates with the same rights it would

80

 

have if it were not the Trustee. Any Agent may do the
same with like rights. However, the Trustee is subject to Trust Indenture Act Sections 310(b) and
311. For purposes of Trust Indenture Act Section 311(b)(4) and (6):

     (a) “cash transaction” means any transaction in which full payment for goods or
securities sold is made within seven days after delivery of the goods or securities in
currency or in checks or other orders drawn upon banks or bankers and payable upon demand;
and

     (b) “self-liquidating paper” means any draft, bill of exchange, acceptance or
obligation which is made, drawn, negotiated or incurred for the purpose of financing the
purchase, processing, manufacturing, shipment, storage or sale of goods, wares or
merchandise and which is secured by documents evidencing title to, possession of, or a
lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the
sale of the goods, wares or merchandise previously constituting the security, provided the
security is received by the Trustee simultaneously with the creation of the creditor
relationship arising from the making, drawing, negotiating or incurring of the draft, bill
of exchange, acceptance or obligation.

     Section 7.04. Trustee’s Disclaimer. The Trustee (i) makes no representation as to the
validity or adequacy of this Indenture or the Notes, (ii) is not accountable for the Company’s use
or application of the proceeds from the Notes and (iii) is not responsible for any statement in the
Notes other than its certificate of authentication.

     Section 7.05. Notice of Default. If any Default occurs and is continuing and is known to the
Trustee, the Trustee will send notice of the Default to each Holder within 90 days after it occurs,
unless the Default has been cured; provided that, except in the case of a default in the payment of
the principal of or interest on any Note, the Trustee may withhold the notice if and so long as the
board of directors, the executive committee or a trust committee of directors of the Trustee in
good faith determines that withholding the notice is in the interest of the Holders. Notice to
Holders under this Section will be given in the manner and to the extent provided in Trust
Indenture Act Section 313(c).

     Section 7.06. Reports by Trustee to Holders. Within 60 days after each May 15, beginning
with May 15, 2009, the Trustee will mail to each Holder, as
provided in Trust Indenture Act Section 313(c), a brief report dated as of such May 15, if
required by Trust Indenture Act Section 313(a), and file such reports with each stock exchange upon
which its Notes are listed and with the SEC as required by Trust Indenture Act Section 313(d).

     Section 7.07. Compensation and Indemnity. (a) The Company will pay the Trustee compensation
as agreed upon in writing for its services. The

81

 

compensation of the Trustee is not limited by any
law on compensation of a Trustee of an express trust. The Company will reimburse the Trustee upon
request for all reasonable out-of-pocket expenses, disbursements and advances incurred or made by
the Trustee, including the reasonable compensation and expenses of the Trustee’s agents and
counsel.

     (b) The Company will indemnify the Trustee for, and hold it harmless against, any loss or
liability or expense incurred by it without negligence or bad faith on its part arising out of or
in connection with the acceptance or administration of this Indenture and its duties under this
Indenture and the Notes, including the costs and expenses of defending itself against any claim or
liability and of complying with any process served upon it or any of its officers in connection
with the exercise or performance of any of its powers or duties under this Indenture and the Notes.

     (c) To secure the Company’s payment obligations in this Section, the Trustee will have a lien
prior to the Notes on all money or property held or collected by the Trustee, in its capacity as
Trustee, except money or property held in trust to pay principal of, and interest on, particular
Notes.

     Section 7.08. Replacement of Trustee. (a) (1) The Trustee may resign at any time by written
notice to the Company.

     (2) The Holders of a majority in aggregate principal amount of the outstanding Notes
may remove the Trustee by written notice to the Trustee.

     (3) If the Trustee is no longer eligible under Section 7.10 or in the circumstances
described in Trust Indenture Act Section 310(b), any Holder that satisfies the
requirements of Trust Indenture Act Section 310(b) may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

     (4) The Company may remove the Trustee if: (i) the Trustee is no longer eligible
under Section 7.10; (ii) the Trustee is adjudged a bankrupt or an insolvent; (iii) a
receiver or other public officer takes charge of the Trustee or its property; or (iv) the
Trustee becomes incapable of acting.

A resignation or removal of the Trustee and appointment of a successor Trustee will become
effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

     (b) If the Trustee has been removed by the Holders, Holders of a majority in aggregate
principal amount of the Notes may appoint a successor Trustee with the consent of the Company.
Otherwise, if the Trustee resigns or is

82

 

removed, or if a vacancy exists in the office of Trustee
for any reason, the Company will promptly appoint a successor Trustee. If the successor Trustee
does not deliver its written acceptance within 30 days after the retiring Trustee resigns or is
removed, the retiring Trustee, the Company or the Holders of a majority in aggregate principal
amount of the outstanding Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

     (c) Upon delivery by the successor Trustee of a written acceptance of its appointment to the
retiring Trustee and to the Company, (i) the retiring Trustee will transfer all property held by it
as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07, (ii) the
resignation or removal of the retiring Trustee will become effective, and (iii) the successor
Trustee will have all the rights, powers and duties of the Trustee under this Indenture. Upon
request of any successor Trustee, the Company will execute any and all instruments for fully and
vesting in and confirming to the successor Trustee all such rights, powers and trusts. The Company
will give notice of any resignation and any removal of the Trustee and each appointment of a
successor Trustee to all Holders, and include in the notice the name of the successor Trustee and
the address of its Corporate Trust Office.

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

     (e) The Trustee agrees to give the notices provided for in, and otherwise comply with, Trust
Indenture Act Section 310(b).

     Section 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all of its corporate trust business to, another
corporation or national banking association, the resulting, surviving or transferee corporation or
national banking association without any further act will be the successor Trustee with the same
effect as if the successor Trustee had been named as the Trustee in this Indenture.

     Section 7.10. Eligibility. This Indenture must always have a Trustee that satisfies the
requirements of Trust Indenture Act Section 310(a) and has a combined capital and surplus of at
least $25,000,000 as set forth in its most recent published annual report of condition.

     Section 7.11. Money Held in Trust. The Trustee will not be liable for interest on any money
received by it except as it may agree with the Company. Money held in trust by the Trustee need
not be segregated from other funds except to the extent required by law and except for money held
in trust under Article 8.

83

 

ARTICLE 8

Defeasance and Discharge

     Section 8.01. Discharge of Company’s Obligations. (a) Subject to paragraph (b), the
Company’s obligations under the Notes and this Indenture, and each Guarantor’s obligations under
its Note Guarantee, will terminate if:

     (1) all Notes previously authenticated and delivered (other than (i) destroyed, lost
or stolen Notes that have been replaced or (ii) Notes that are paid pursuant to Section
4.01 or (iii) Notes for whose payment money or U.S. Government Obligations have been held
in trust and then repaid to the Company pursuant to Section 8.05) have been delivered to
the Trustee for cancellation and the Company has paid all sums payable by it hereunder; or

     (2) (A) the Notes mature within sixty days, or all of them are to be called
for redemption within sixty days under arrangements satisfactory to the Trustee
for giving the notice of redemption,

          (B) the Company irrevocably deposits in trust with the Trustee, as trust
funds solely for the benefit of the Holders, money or U.S. Government Obligations
or a combination thereof sufficient, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certificate
delivered to the Trustee, without consideration of any reinvestment, to pay
principal of and interest on the Notes to final Stated Maturity or redemption, as
the case may be, and to pay all other sums payable by it hereunder, and

          (C) the Company delivers to the Trustee an Officers’ Certificate and an
Opinion of Counsel, in each case stating that all conditions precedent provided
for herein relating to the satisfaction and discharge of this Indenture have been
complied with.

     (b) After satisfying the conditions in clause (1), only the Company’s obligations under
Section 7.07 will survive. After satisfying the conditions in clause (2), only the Company’s
obligations in Article 2 and Sections 4.02, 7.07, 7.08, 8.05 and 8.06 will survive. In
either case, the Trustee upon request will
acknowledge in writing the discharge of the Company’s obligations under the Notes and this
Indenture other than the surviving obligations.

     Section 8.02. Legal Defeasance. After the 91st day following the deposit referred
to in clause (1) of this Section 8.02, the Company will be deemed to have paid and will be
discharged from its obligations in respect of the Notes and this Indenture, other than its
obligations in Article 2 and Sections 4.02, 7.07, 7.08,

84

 

8.05 and 8.06, and each Guarantor’s
obligations under its Note Guarantee will terminate, provided the following conditions have been
satisfied:

     (1) The Company has irrevocably deposited in trust with the Trustee, as trust funds
solely for the benefit of the Holders, money or U.S. Government Obligations or a
combination thereof sufficient, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certificate thereof delivered to the
Trustee, without consideration of any reinvestment, to pay principal of and interest on
the Notes to final Stated Maturity or redemption, as the case may be, provided that any
redemption before maturity has been irrevocably provided for under arrangements
satisfactory to the Trustee.

     (2) No Default has occurred and is continuing on the date of the deposit or occurs at
any time during the 91-day period following the deposit (other than a Default relating to
the borrowing of funds to make such deposit).

     (3) The deposit will not result in a breach or violation of, or constitute a default
under any agreement or instrument (other than this Indenture) to which the Company is a
party or by which it is bound.

     (4) The Company has delivered to the Trustee either (x) a ruling received from the
Internal Revenue Service to the effect that the Holders will not recognize income, gain or
loss for federal income tax purposes as a result of the defeasance and will be subject to
federal income tax on the same amount and in the same manner and at the same times as
would otherwise have been the case or (y) an Opinion of Counsel, based on a change in law
after the date of this Indenture, to the same effect as the ruling described in clause
(x).

     (5) The Company has delivered to the Trustee an Officers’ Certificate and an Opinion
of Counsel, in each case stating that all conditions precedent provided for herein
relating to the defeasance have been complied with.

     Prior to the end of the 91-day period, none of the Company’s obligations under this Indenture
will be discharged. Thereafter, the Trustee upon request will
acknowledge in writing the discharge of the Company’s obligations under the Notes and this
Indenture except for the surviving obligations specified above.

     Section 8.03. Covenant Defeasance. After the 91st day following the deposit
referred to in clause (1) of this Section 8.03, the Company’s obligations set forth in Sections
4.06 through 4.18 inclusive, clauses (a), (b) and (c) of Section 4.20, and clauses (3) and (5)
of Section 5.01(a), and each Guarantor’s obligations under its Note Guarantee, will terminate, and
clauses (3), (4), (5), (6) and (9) of

85

 

Section 6.01 will no longer constitute Events of Default,
provided the following conditions have been satisfied:

     (1) The Company has complied with clauses (1), (2), (3) and (5) of Section 8.02; and

     (2) 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 the defeasance and will be subject to federal income tax on the same amount and
in the same manner and at the same times as would otherwise have been the case.

     Except as specifically stated above, none of the Company’s obligations under this Indenture,
or any Guarantor’s obligations under its Note Guarantee, will be discharged.

     Section 8.04. Application of Trust Money. Subject to Section 8.05, the Trustee will hold in
trust the money or U.S. Government Obligations deposited with it pursuant to Section 8.01, 8.02
or 8.03, and apply the deposited money and the proceeds from deposited U.S. Government Obligations
to the payment of principal of and interest on the Notes in accordance with the Notes and this
Indenture. Such money and U.S. Government Obligations need not be segregated from other funds
except to the extent required by law.

     Section 8.05. Repayment to Company. Subject to Sections 7.07, 8.01, 8.02 and 8.03, the
Trustee will promptly pay to the Company upon request any excess money held by the Trustee at any
time and thereupon be relieved from all liability with respect to such money. The Trustee will pay
to the Company upon request any money held for payment with respect to the Notes that remains
unclaimed for two years, provided that, if any Certificated Note is then outstanding, before making
such payment the Trustee may at the expense of the Company publish once in a newspaper of general
circulation in New York City, or send to each Holder entitled to such money, notice that the money
remains unclaimed and that after a date specified in the notice (at least 30 days after the date of
the publication or notice) any remaining unclaimed balance of money will be repaid to the Company.
After payment to the Company, Holders entitled to such money must look solely to the Company for
payment, unless applicable law
designates another Person, and all liability of the Trustee with respect to such money will
cease.

     Section 8.06. Reinstatement. If and for so long as the Trustee is unable to apply any money
or U.S. Government Obligations held in trust pursuant to Section 8.01, 8.02 or 8.03 by reason of
any legal proceeding or by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under
this Indenture and the Notes will be reinstated as though no such deposit in trust had

86

 

been made.
If the Company makes any payment of principal of or interest on any Notes because of the
reinstatement of its obligations, it will be subrogated to the rights of the Holders of such Notes
to receive such payment from the money or U.S. Government Obligations held in trust.

ARTICLE 9

Amendments, Supplements and Waivers

     Section 9.01. Amendments Without Consent of Holders. The Company, the Guarantors and the
Trustee may amend, modify or supplement this Indenture or the Notes without notice to or the
consent of any Noteholder

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

     (2) to comply with Article 5;

     (3) to comply with any requirements of the SEC in connection with the qualification
of this Indenture under the Trust Indenture Act;

     (4) to evidence and provide for the acceptance of an appointment hereunder by a
successor Trustee;

     (5) to provide for uncertificated Notes in addition to or in place of certificated

of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are
described in Section 163(f)(2)(B) of the Code;

     (6) to provide for any Guarantee of the Notes, to secure the Notes or to confirm and
evidence the release, termination or discharge of any Guarantee of or Lien securing the
Notes when such release, termination or discharge is permitted by this Indenture;

     (7) to provide for or confirm the issuance of Additional Notes;

     (8) to conform the text of this Indenture or the Notes to any provision of the
“Description of the Notes” section of the Offering Memorandum to the extent that such
provision in such “Description of the Notes” section was intended to be a verbatim
recitation of a provision of this Indenture or the Notes; or

     (9) to make any other change that does not materially and adversely affect the rights
of any Holder.

87

 

     Section 9.02. Amendments With Consent of Holders. (a) Except as otherwise provided in
Sections 6.02, 6.04 and 6.07 or paragraph (b), the Company, the Guarantors and the Trustee may
amend, modify or supplement this Indenture and the Notes with the consent of the Holders of a
majority in aggregate principal amount of the outstanding Notes, and the Holders of a majority in
aggregate principal amount of the outstanding Notes by written notice to the Trustee may waive
future compliance by the Company with any provision of this Indenture or the Notes.

     (b) Notwithstanding the provisions of paragraph (a), without the consent of each Holder
affected, an amendment, modification, supplement or waiver may not

     (1) reduce the principal amount of or change the Stated Maturity of any installment
of principal of any Note,

     (2) reduce the rate of or change the Stated Maturity of any interest payment on any
Note,

     (3) reduce the amount payable upon the optional redemption of any Note or change the
times at which any Note may be redeemed or, once notice of redemption has been given, the
time at which it must thereupon be redeemed,

     (4) after the time an Offer to Purchase is required to have been made, reduce the
purchase amount or purchase price, or extend the latest expiration date or purchase date
thereunder,

     (5) make any Note payable in money other than that stated in the Note,

     (6) impair the right of any Holder of Notes to receive any principal payment or
interest payment on such Holder’s Notes, on or after the Stated Maturity thereof, or to
institute suit for the enforcement of any such payment,

     (7) make any change in the percentage of the principal amount of the Notes required
for amendments or waivers,

     (8) modify or change any provision of this Indenture affecting the ranking of the
Notes or any Note Guarantee in a manner adverse to the Holders of the Notes or

     (9) make any change in any Note Guarantee that would adversely affect the
Noteholders.

88

 

     (c) It is not necessary for Noteholders to approve the particular form of any proposed
amendment, modification, supplement or waiver, but is sufficient if their consent approves the
substance thereof.

     (d) An amendment, modification, supplement or waiver under this Section will become effective
on receipt by the Trustee of consents from the Holders of the requisite percentage in principal
amount of the outstanding Notes. After an amendment, modification, supplement or waiver under this
Section becomes effective, the Company will send to the Holders affected thereby a notice briefly
describing the amendment, modification, supplement or waiver. The Company will send copies of any
documents pursuant to which any such amendment, modification, supplement or waiver has been
effected to Holders upon request. Any failure of the Company to send such notice or copies, or any
defect therein, will not, however, in any way impair or affect the validity of any such amendment,
modification, supplement or waiver.

     Section 9.03. Effect of Consent. (a) After an amendment, supplement or waiver becomes
effective, it will bind every Holder unless it is of the type requiring the consent of each Holder
affected. If the amendment, supplement or waiver is of the type requiring the consent of each
Holder affected, the amendment, supplement or waiver will bind each Holder that has consented to it
and every subsequent Holder of a Note that evidences the same debt as the Note of the consenting
Holder.

     (b) If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require
the Holder to deliver it to the Trustee so that the Trustee may place an appropriate notation of
the changed terms on the Note and return it to the Holder, or exchange it for a new Note that
reflects the changed terms. The Trustee may also place an appropriate notation on any Note
thereafter authenticated. However, the effectiveness of the amendment, supplement or waiver is not
affected by any failure to annotate or exchange Notes in this fashion.

     Section 9.04. Trustee’s Rights and Obligations. The Trustee is entitled to receive, and will
be fully protected in relying upon, an Opinion of Counsel stating that the execution of any
amendment, supplement or waiver authorized pursuant to this Article is authorized or permitted by
this Indenture. If the Trustee has received such an Opinion of Counsel, it shall sign the
amendment, supplement or waiver so long as the same does not adversely affect the rights of the
Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or
waiver that affects the Trustee’s own rights, duties or immunities under this Indenture.

     Section 9.05. Conformity With Trust Indenture Act. Every supplement to this Indenture
executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

89

 

     Section 9.06. Payments for Consents. Neither the Company nor any of its Restricted
Subsidiaries may, directly or indirectly, pay or cause to be paid any consideration, whether by way
of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver,
amendment or modification of any of the terms or provisions of this Indenture or the Notes unless
such consideration is offered to be paid or agreed to be paid to all Holders of the Notes that
consent, waive or agree to amend or modify such term or provision within the time period set forth
in the solicitation documents relating to the consent, waiver, amendment or modification.

ARTICLE 11

Guarantees

     Section 11.01. The Guarantees. Subject to the provisions of this Article, each Guarantor
hereby fully and unconditionally Guarantees, jointly and severally, on an unsecured basis, the full
and punctual payment (whether at Stated Maturity, upon redemption, purchase pursuant to an Offer to
Purchase or acceleration, or otherwise) of the principal of, premium, if any, and interest on, and
all other amounts payable under, each Note, and the full and punctual payment of all other amounts
payable by the Company under this Indenture. Upon failure by the Company to pay punctually any
such amount, each Guarantor shall forthwith on demand pay the amount not so paid at the place and
in the manner specified in this Indenture.

     Section 11.02. Guarantee Unconditional. The obligations of each Guarantor hereunder are
unconditional and absolute and, without limiting the generality of the foregoing, will not be
released, discharged or otherwise affected by

     (1) any extension, renewal, settlement, compromise, waiver or release in respect of
any obligation of the Company under this Indenture or any Note, by operation of law or
otherwise;

     (2) any modification or amendment of or supplement to this Indenture or any Note;

     (3) any change in the corporate existence, structure or ownership of the Company, or
any insolvency, bankruptcy, reorganization or other similar proceeding affecting the
Company or its assets or any resulting release or discharge of any obligation of the
Company contained in this Indenture or any Note;

90

 

     (4) the existence of any claim, set-off or other rights which the Guarantor may have
at any time against the Company, the Trustee or any other Person, whether in connection
with this Indenture or any unrelated transactions, provided that nothing herein prevents
the assertion of any such claim by separate suit or compulsory counterclaim;

     (5) any invalidity or unenforceability relating to or against the Company for any
reason of this Indenture or any Note, or any provision of applicable law or regulation
purporting to prohibit the payment by the Company of the principal of or interest on any
Note or any other amount payable by the Company under this Indenture; or

     (6) any other act or omission to act or delay of any kind by the Company, the Trustee
or any other Person or any other circumstance whatsoever which might, but for the
provisions of this paragraph, constitute a legal or equitable discharge of or defense to
such Guarantor’s obligations hereunder, other than payment in full of the principal of,
premium, if any, and interest on the Notes and all other amounts payable by the Company
under this Indenture.

     Section 11.03. Discharge; Reinstatement. Subject to Section 11.09, each Guarantor’s
obligations hereunder will remain in full force and effect until the principal of, premium, if any,
and interest on the Notes and all other amounts payable by the Company under this Indenture have
been paid in full. If at any time any payment of the principal of, premium, if any, or interest on
any Note or any other amount payable by the Company under this Indenture is rescinded or must be
otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or
otherwise, each Guarantor’s obligations hereunder with respect to such payment will be reinstated
as though such payment had been due but not made at such time.

     Section 11.04. Waiver by the Guarantors. Each Guarantor irrevocably waives acceptance
hereof, presentment, demand, protest and any notice not provided for herein, as well as any
requirement that at any time any action be taken by any Person against the Company or any other
Person.

     Section 11.05. Subrogation and Contribution. Upon making any payment with respect to any
obligation of the Company under this Article, the Guarantor making such payment will be subrogated
to the rights of the payee against the Company with respect to such obligation, provided that the
Guarantor may not enforce either any right of subrogation, or any right to receive payment in the
nature of contribution, or otherwise, from any other Guarantor, with respect to such payment so
long as any amount payable by the Company hereunder or under the Notes remains unpaid.

91

 

     Section 11.06. Stay of Acceleration. If acceleration of the time for payment of any amount
payable by the Company under this Indenture or the Notes is stayed upon the insolvency, bankruptcy
or reorganization of the Company, all such amounts otherwise subject to acceleration under the
terms of this Indenture are nonetheless payable by the Guarantors hereunder forthwith on demand by
the Trustee or the Holders.

     Section 11.07. Limitation on Amount of Guarantee. Notwithstanding anything to the contrary
in this Article, each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that
it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a
fraudulent conveyance under applicable fraudulent conveyance provisions of the United States
Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the
Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each
Guarantor under its Note Guarantee are limited to the maximum amount that would not render the
Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of
the United States Bankruptcy Code or any comparable provision of state law.

     Section 11.08. Execution and Delivery of Guarantee. The execution by each Guarantor of this
Indenture (or a Supplemental Indenture) evidences the Note Guarantee of such Guarantor, whether or
not the person signing as an officer of the Guarantor still holds that office at the time of
authentication of any Note. The delivery of any Note by the Trustee after authentication
constitutes due delivery of the Note Guarantee set forth in this Indenture on behalf of each
Guarantor.

     Section 11.09. Release of Note Guarantee. The Note Guarantee of a Guarantor will terminate
upon

     (1) a sale or other disposition of all or substantially all of the assets of that
Guarantor (including by way of consolidation or merger) to a Person that is not (either
before or after giving effect to such transaction) the Company or a Restricted Subsidiary,
if the sale or other disposition is permitted by this Indenture,

     (2) a sale or other disposition of all or substantially all of the Capital Stock of
that Guarantor to a Person that is not (either before or after giving effect to such
transaction) the Company or a Restricted Subsidiary, if the sale or other disposition is
permitted by this Indenture,

     (3) if the Note Guarantee was required pursuant to the terms of this Indenture, the
cessation of the circumstances requiring the Note Guarantee,

92

 

     (4) the designation in accordance with this Indenture of the Guarantor as an
Unrestricted Subsidiary, or

     (5) defeasance or discharge of the Notes, as provided in Article 8.

     Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of
Counsel to the foregoing effect, the Trustee will execute any documents reasonably required in
order to evidence the release of the Guarantor from its obligations under its Note Guarantee.

ARTICLE 12

Miscellaneous

     Section 12.01. Trust Indenture Act of 1939. This Indenture shall incorporate and be governed
by the provisions of the Trust Indenture Act that are required to be part of and to govern
indentures qualified under the Trust Indenture Act.

     Section 12.02. Noteholder Communications; Noteholder Actions. (a) The rights of Holders to
communicate with other Holders with respect to this Indenture or the Notes are as provided by the
Trust Indenture Act, and the Company and the Trustee shall comply with the requirements of Trust
Indenture Act Sections 312(a) and 312(b). Neither the Company nor the Trustee will be held
accountable by reason of any disclosure of information as to names and addresses of Holders made
pursuant to the Trust Indenture Act.

     (b) (1) Any request, demand, authorization, direction, notice, consent to amendment,
supplement or waiver or other action provided by this Indenture to be given or taken by a
Holder (an “act”) may be evidenced by an instrument signed by the Holder delivered to the
Trustee. The fact and date of the execution of the instrument, or the authority of the
person executing it, may be proved in any manner that the Trustee deems sufficient.

     (2) The Trustee may make reasonable rules for action by or at a meeting of Holders,
which will be binding on all the Holders.

     (c) Any act by the Holder of any Note binds that Holder and every subsequent Holder of a Note
that evidences the same debt as the Note of the acting Holder, even if no notation thereof appears
on the Note. Subject to paragraph (d), a Holder may revoke an act as to its Notes, but only if the
Trustee receives the notice of revocation before the date the amendment or waiver or other
consequence of the act becomes effective.

93

 

     (d) The Company may, but is not obligated to, fix a record date (which need not be within the
time limits otherwise prescribed by Trust Indenture Act Section 316(c)) for the purpose of
determining the Holders entitled to act with respect to any amendment or waiver or in any other
regard, except that during the continuance of an Event of Default, only the Trustee may set a
record date as to notices of default, any declaration or acceleration or any other remedies or
other consequences of the Event of Default. If a record date is fixed, those Persons that were
Holders at such record date and only those Persons will be entitled to act, or to revoke any
previous act, whether or not those Persons continue to be Holders after the record date. No act
will be valid or effective for more than 90 days after the record date.

     Section 12.03. Notices. (a) Any notice or communication to the Company will be deemed given
if in writing in the English language (i) when delivered in person or (ii) five days after mailing

Any notice to the Trustee will be effective only upon receipt. In each case the notice or
communication should be addressed as follows:

94

 

time.
Defect in mailing a notice or communication to any particular Holder will not affect its
sufficiency with respect to other Holders.

     (c) Where this Indenture provides for notice, the notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and the waiver will be
the equivalent of the notice. Waivers of notice by Holders must be filed with the Trustee, but
such filing is not a condition precedent to the validity of any action taken in reliance upon such
waivers.

     Section 12.04. Certificate and Opinion as to Conditions Precedent. Upon any request or
application by the Company to the Trustee to take any action under this Indenture, the Company will

conditions precedent, if any, provided for in this Indenture relating to the proposed
action have been complied with; and

complied with.

covenant or condition and the related definitions;

     (2) a brief statement as to the nature and scope of the examination or investigation
upon which the statement or opinion contained in the certificate or opinion is based;

     (3) a statement that, in the opinion of each such person, that person has made such
examination or investigation as is necessary to enable the person to express an informed
opinion as to whether or not such covenant or condition has been complied with; and

     (4) a statement as to whether or not, in the opinion of each such person, such
condition or covenant has been complied with, provided that
an Opinion of Counsel may rely on an Officers’ Certificate or certificates of public
officials with respect to matters of fact.

     Section 12.06. Payment Date Other Than a Business Day. If any payment with respect to a
payment of any principal of, premium, if any, or interest on any Note (including any payment to be
made on any date fixed for redemption or purchase of any Note) is due on a day which is not a
Business Day, then the payment need not be made on such date, but may be made on the next

95

 

Business
Day with the same force and effect as if made on such date, and no interest will accrue for the
intervening period.

its successor.

     Section 12.10. Duplicate Originals. The parties may sign any number of copies of this
Indenture. Each signed copy shall be an original, but all of them together represent the same
agreement.

     Section 12.11. Separability. In case any provision in this Indenture or in the Notes is
invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining
provisions will not in any way be affected or impaired thereby.

     Section 12.12. Table of Contents and Headings. The Table of Contents, Cross-Reference Table
and headings of the Articles and Sections of this Indenture have been inserted for convenience of
reference only, are not to be considered a part of this Indenture and in no way modify or restrict
any of the terms and provisions of this Indenture.

     Section 12.13. No Liability of Directors, Officers, Employees, Incorporators, Members and
Stockholders. No director, officer, employee, incorporator, member, partner or stockholder of the
Company or any Guarantor, as such, will have any liability for any obligations of the Company or
such Guarantor under the Notes, any Note Guarantee or this Indenture or for any claim based on, in
respect of, or by reason of, such obligations. Each Holder of Notes
by accepting a Note waives and releases all such liability. The waiver and release are part of
the consideration for issuance of the Notes.

any applicable grace periods) at a rate per annum of 9.875%. Interest not paid when due and any

     (b) Holders of Transfer Restricted Securities. A Person is deemed to be a holder of Transfer
Restricted Securities (each, a “Holder”) whenever such Person owns Transfer Restricted Securities.

     Section 3. Registered Exchange Offer.

     (a) If any of the Initial Securities are not Freely Tradable by the 366th calendar
day following the Closing Date, then, unless the Exchange Offer shall not be permissible under
applicable law or Commission policy (after the procedures set forth in Section 6(a) below have been
complied with), the Company and the Guarantors shall (i) file with the Commission an Exchange Offer
Registration Statement with respect to a registered offer to exchange the Initial Securities for
Exchange Securities under the Indenture in the same aggregate principal amount as and with terms
that shall be identical in all respects to the Initial Securities (except that the Exchange
Securities shall not contain terms with respect to the interest rate step-up provision and transfer
restrictions), (ii) use their commercially reasonable best efforts to cause such Exchange Offer
Registration Statement to become effective under the Securities Act, (iii) in connection with the
foregoing, file (A) all pre-effective amendments to such Exchange Offer Registration Statement as
may be necessary in order to cause such Exchange Offer Registration Statement to become effective,
(B) if applicable, a post-effective amendment to such Exchange Offer Registration Statement
pursuant to Rule 430A under the Securities Act and (C) cause all necessary filings in connection
with the registration and qualification of the Exchange Securities to be made under the Blue Sky
laws of such jurisdictions as are necessary to permit Consummation of the Exchange Offer, and (iv)
promptly after such Exchange Offer Registration Statement is declared effective, commence the
Exchange Offer. The Exchange Offer Registration Statement shall be on the appropriate form
permitting registration of the Exchange Securities to be offered in exchange for the Transfer
Restricted Securities and to permit resales of Securities held by Broker-Dealers as contemplated by
Section 3(c) below.

     (b) If an Exchange Offer Registration Statement is required pursuant to Section 3(a) above,
the Company and the Guarantors shall cause the Exchange Offer Registration Statement to be
effective continuously and shall use their commercially reasonable best efforts to keep the
Exchange Offer open for not less than 30 calendar days (or longer if required by applicable law)

4

 

after the date notice of the Exchange Offer is mailed to the Holders. The Company and the
Guarantors shall cause each Exchange Offer to comply with all applicable federal and state
securities laws. No securities other than the Securities (and guarantees thereof) shall be
included in the Exchange Offer Registration Statement. If an Exchange Offer Registration Statement
is required pursuant to Section 3(a) above, the Company and the Guarantors shall use their
commercially reasonable best efforts to Consummate the Exchange Offer, on or prior to the
366th calendar day following the Closing Date.

     (c) The Company shall indicate in a “Plan of Distribution” section contained in the
Prospectus forming a part of any Exchange Offer Registration Statement that any Broker-Dealer who
holds Initial Securities that are Transfer Restricted Securities and that were acquired for its own
account as a result of market-making activities or other trading activities (other than Transfer
Restricted Securities acquired directly from the Company), may exchange such Initial Securities
pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed to be an “underwriter”
within the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the
requirements of the Securities Act in connection with any resales of the Exchange Securities
received by such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may be
satisfied by the delivery by such Broker-Dealer of the Prospectus contained in the Exchange Offer
Registration Statement. Such “Plan of Distribution” section shall also contain all other
information with respect to such resales by Broker-Dealers that the Commission may require in order
to permit such resales pursuant thereto, but such “Plan of Distribution” shall not name any such
Broker-Dealer or disclose the amount of Securities held by any such Broker-Dealer except to the
extent required by the Commission as a result of a change in policy after the date of this
Agreement.

     If an Exchange Offer Registration Statement is required pursuant to Section 3(a) above, the
Company and the Guarantors shall use their commercially reasonable best efforts to keep the
Exchange Offer Registration Statement continuously effective, supplemented and amended as required
by the provisions of Section 6(c) below to the extent necessary to ensure that it is available for
resales of Securities acquired by Broker-Dealers for their own accounts as a result of
market-making activities or other trading activities, and to ensure that it conforms with the
requirements of this Agreement, the Securities Act and the policies, rules and regulations of the
Commission as announced from time to time, for a period ending on the earlier of (i) 180 days from
the date on which the Exchange Offer Registration Statement is declared effective and (ii) the date
on which Broker-Dealers are no longer required to deliver a prospectus in connection with
market-making or other trading activities.

     The Company shall provide sufficient copies of the latest version of such Prospectus to
Broker-Dealers promptly upon request at any time during such 180-day (or shorter as provided in the
foregoing sentence) period in order to facilitate such resales.

     Section 4. Shelf Registration.

     (a) Shelf Registration. If any of the Initial Securities are not Freely Tradable by the
366th calendar day after the Closing Date and either (i) the Company and the Guarantors
are not required to file an Exchange Offer Registration Statement or to consummate the Exchange
Offer for a series of Initial Securities because the Exchange Offer is not permitted by applicable
law or

5

 

Commission policy (after the procedures set forth in Section 6(a) below have been complied
with), (ii) for any reason the Exchange Offer for a series of Securities is not Consummated within
366 calendar days following the Closing Date, or (iii) with respect to any Holder of Transfer
Restricted Securities (A) such Holder is prohibited by applicable law or Commission policy from
participating in the Exchange Offer, or (B) such Holder may not resell the Exchange Securities
acquired by it in the Exchange Offer to the public without delivering a prospectus and that the
Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available
for such resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Initial Securities
acquired directly from the Company or one of its affiliates, then, upon such Holder’s request, the
Company and the Guarantors shall

     (x) cause to be filed, at their expense, a shelf registration statement pursuant to
Rule 415 under the Securities Act, which may be an amendment to the Exchange Offer
Registration Statement (in either event, the “Shelf Registration Statement”) as promptly as
practicable, and in any event on or prior to the 30th calendar day after such
filing obligation arises (the “Shelf Filing Deadline”), which Shelf Registration Statement
shall provide for resales of all Transfer Restricted Securities the Holders of which shall
have provided the information required pursuant to Section 4(b) hereof; and

     (y) use their commercially reasonable best efforts to cause such Shelf Registration
Statement to be declared effective under the Securities Act on or before the
120th calendar day after the Shelf Filing Deadline.

     The Company and the Guarantors shall keep any such Shelf Registration Statement continuously
effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof
to the extent necessary to ensure that it is available for resales of Securities by the Holders of
Transfer Restricted Securities entitled to the benefit of this Section 4(a), and to ensure that it
conforms with the requirements of this Agreement, the Securities Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of two years following
the effective date of such Shelf Registration Statement (or such shorter period that will terminate
when all the Securities covered by such Shelf Registration Statement have been sold pursuant to
such Shelf Registration Statement).

     (b) Provision by Holders of Certain Information in Connection with the Shelf Registration
Statement. No Holder of Transfer Restricted Securities may include any of its Transfer Restricted
Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such
Holder furnishes to the Company in writing, within 20 business days after receipt of a request
therefor, such information as the Company may reasonably request for use in connection with any
Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. Each Holder
as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the
Company all information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

     Section 5. Additional Interest. If any of the Initial Securities are not Freely
Tradable by the 366th calendar day after the Closing Date and either (a) the applicable
Exchange Offer is not consummated on or prior to the 366th calendar day following the
applicable Closing Date, (b) a

6

 

Shelf Registration Statement applicable to the Securities is not filed or declared effective
when required, or (c) a Registration Statement applicable to the Securities is declared effective
as required but thereafter fails to remain effective or becomes usable in connection with resales
for more than 30 calendar days (each such event referred to in clauses (a) through (c) above, a
"Registration Default”), the Company shall pay liquidated damages in the form of additional
interest (“Additional Interest”) in cash to each Holder of Securities in an amount equal to 0.25%
per annum of the aggregate principal amount of Securities for the period of occurrence of the
Registration Default until the earlier of all of the Initial Securities being Freely Tradable and
such time as no Registration Default is in effect, which rate shall increase by 0.25% per annum for
each subsequent 90-day period during which such Registration Default continues up to a maximum of
0.50% per annum. Following the cure of all Registration Defaults, Additional Interest will cease
to accrue and the interest rate on the Securities will revert to the original rate; provided,
however, that, if after the date such Additional Interest ceases to accrue, a different
Registration Default occurs, Additional Interest may again commence accruing pursuant to the
foregoing provisions.

     All obligations of the Company and the Guarantors set forth in the preceding paragraph that
are outstanding with respect to any Transfer Restricted Security at the time such security ceases
to be a Transfer Restricted Security shall survive until such time as all such obligations with
respect to such Note shall have been satisfied in full.

     Section 6. Registration Procedures.

     (a) Exchange Offer Registration Statement. In connection with each Exchange Offer, the
Company and the Guarantors shall comply with all of the provisions of Section 6(c) below, shall use
their commercially reasonable best efforts to effect such exchange to permit the sale of Transfer
Restricted Securities being sold in accordance with the intended method or methods of distribution
thereof, and shall comply with all of the following provisions:

     (i) If in the reasonable opinion of counsel to the Company there is a question as to
whether the Exchange Offer is permitted by applicable law, the Company and the Guarantors
hereby agree to seek a no-action letter or other favorable decision from the Commission
allowing the Company and the Guarantors to Consummate the Exchange Offer for the Initial
Securities. The Company and the Guarantors each hereby agree to pursue the issuance of such
a decision to the Commission staff level but shall not be required to take commercially
unreasonable action to effect a change of Commission policy. The Company and the Guarantors
each hereby agree, however, to (A) participate in telephonic conferences with the
Commission, (B) deliver to the Commission staff an analysis prepared by counsel to the
Company setting forth the legal bases, if any, upon which such counsel has concluded that
such Exchange Offer should be permitted and (C) diligently pursue a favorable resolution by
the Commission staff of such submission.

     (ii) As a condition to its participation in an Exchange Offer pursuant to the terms of
this Agreement, each Holder of Transfer Restricted Securities shall furnish, upon the
request of the Company, prior to the Consummation thereof, a written representation to the
Company (which may be contained in the letter of transmittal contemplated by the Exchange
Offer Registration Statement) to the effect that (A) it is not an affiliate of the

7

 

Company, (B) it is acquiring the Exchange Securities in its ordinary course of business
and (C) at the time of the commencement of the Exchange Offer, it has no arrangement with
any person to participate in the distribution (within the meaning of the Securities Act) of
the Exchange Securities to be issued in the Exchange Offer. In addition, all such Holders
of Transfer Restricted Securities shall otherwise cooperate in the Company’s preparations
for the Exchange Offer. Each Holder will be required to acknowledge and agree that any
Broker-Dealer and any such Holder using the Exchange Offer to participate in a distribution
of the securities to be acquired in the Exchange Offer (1) could not under Commission policy
as in effect on the date of this Agreement rely on the position of the Commission enunciated
in Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings
Corporation (available May 13, 1988), as interpreted in the Commission’s letter to Shearman
& Sterling dated July 2, 1993, and similar no-action letters (which may include any
no-action letter obtained pursuant to clause (i) above), and (2) must comply with the
registration and prospectus delivery requirements of the Securities Act in connection with a
secondary resale transaction and that such a secondary resale transaction should be covered
by an effective registration statement containing the selling security holder information
required by Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange
Securities obtained by such Holder in exchange for Initial Securities acquired by such
Holder directly from the Company.

     (b) Shelf Registration Statement. In connection with the Shelf Registration Statement, the
Company and the Guarantors shall comply with all the provisions of Section 6(c) below and shall use
their commercially reasonable best efforts to effect such registration to permit the sale of the
Transfer Restricted Securities being sold in accordance with the intended method or methods of
distribution thereof, and pursuant thereto the Company and the Guarantors will as expeditiously as
possible prepare and file with the Commission a Registration Statement relating to the registration
on any appropriate form under the Securities Act, which form shall be available for the sale of the
Transfer Restricted Securities in accordance with the intended method or methods of distribution
thereof.

     (c) General Provisions. In connection with any Registration Statement and any Prospectus
required by this Agreement to permit the sale or resale of Transfer Restricted Securities
(including, without limitation, any Registration Statement and the related Prospectus required to
permit resales of Securities by Broker-Dealers), the Company and each of the Guarantors shall:

     (i) use its commercially reasonable best efforts to keep such Registration Statement
continuously effective and provide all requisite financial statements (including, if
required by the Securities Act or any regulation thereunder, financial statements of the
Guarantors) for the period specified in Section 3 or 4 of this Agreement, as applicable;
upon the occurrence of any event that would cause any such Registration Statement or the
Prospectus contained therein (A) to contain a material misstatement or omission or (B) not
to be effective and usable for resale of Transfer Restricted Securities during the period
required by this Agreement, the Company shall file promptly an appropriate amendment to such
Registration Statement, in the case of clause (A), correcting any such misstatement or
omission, and, in the case of either clause (A) or (B), use its

8

 

commercially reasonable best efforts to cause such amendment to be declared effective
and such Registration Statement and the related Prospectus to become usable for their
intended purposes as soon as practicable thereafter;

     (ii) prepare and file with the Commission such amendments and post-effective
amendments to such Registration Statement as may be necessary to keep such Registration
Statement effective for the applicable period set forth in Section 3 or 4 hereof, as
applicable, or such shorter period as will terminate when all Transfer Restricted Securities
covered by such Registration Statement have been sold; cause the Prospectus to be
supplemented by any required Prospectus supplement, and as so supplemented to be filed
pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable
provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply
with the provisions of the Securities Act with respect to the disposition of all securities
covered by such Registration Statement during the applicable period in accordance with the
intended method or methods of distribution by the sellers thereof set forth in such
Registration Statement or supplement to the Prospectus;

     (iii) advise the underwriter(s), if any, and selling Holders promptly and, if
requested by such Persons, confirm such advice in writing, (A) when the Prospectus or any
prospectus supplement or post-effective amendment has been filed, and, with respect to any
Registration Statement or any post-effective amendment thereto, when the same has become
effective, (B) of any request by the Commission for amendments to the Registration Statement
or amendments or supplements to the Prospectus or for additional information relating
thereto, (C) of the issuance by the Commission of any stop order suspending the
effectiveness of such Registration Statement under the Securities Act or of the suspension
by any state securities commission of the qualification of the Transfer Restricted
Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for
any of the preceding purposes, or (D) of the existence of any fact or the happening of any
event that makes any statement of a material fact made in such Registration Statement, the
Prospectus, any amendment or supplement thereto, or any document incorporated by reference
therein untrue, or that requires the making of any additions to or changes in such
Registration Statement or the Prospectus in order to make the statements therein not
misleading. If at any time the Commission shall issue any stop order suspending the
effectiveness of the Registration Statement, or any state securities commission or other
regulatory authority shall issue an order suspending the qualification or exemption from
qualification of the Transfer Restricted Securities under state securities or Blue Sky laws,
the Company and the Guarantors shall use their commercially reasonable best efforts to
obtain the withdrawal or lifting of such order at the earliest possible time;

     (iv) furnish without charge to each of the Initial Purchasers, each selling Holder
named in any Registration Statement, and each of the underwriter(s), if any, before filing
with the Commission, copies of any Registration Statement or any Prospectus included therein

all documents incorporated by reference after the initial filing of such Registration
Statement), which documents will be subject to the review of such Holders and underwriter(s)
in connection with such sale, if any, for a period of at least

five business days, and the Company will not file any such Registration Statement or
Prospectus or any amendment or supplement to any such Registration Statement or Prospectus
(including all such documents incorporated by reference) to which an Initial Purchaser of
Transfer Restricted Securities covered by such Registration Statement or the underwriter(s),
if any, shall reasonably object in writing within five business days after the receipt
thereof (such objection to be deemed timely made upon confirmation of telecopy transmission
within such period). The objection of an Initial Purchaser or underwriter, if any, shall be
deemed to be reasonable if such Registration Statement, amendment, Prospectus or supplement,
as applicable, as proposed to be filed, contains a material misstatement or omission;

     (v) promptly prior to the filing of any document that is to be incorporated by
reference into a Registration Statement or Prospectus, provide copies of such document to
the Initial Purchasers, each selling Holder named in any Registration Statement, and to the
underwriter(s), if any, make representatives of the Company and of the Guarantors available
for discussion of such document and other customary due diligence matters, and include such
information in such document prior to the filing thereof as such selling Holders or
underwriter(s), if any, reasonably may request;

     (vi) make available at reasonable times for inspection by the Initial Purchasers, any
managing underwriter participating in any disposition pursuant to such Registration
Statement and any attorney or accountant retained by such Initial Purchasers or any of the

subsequent to the filing thereof and prior to its effectiveness;

     (vii) if requested by any selling Holders or the underwriter(s), if any, promptly
incorporate in any Registration Statement or Prospectus, pursuant to a supplement or
post-effective amendment if necessary, such information as such selling Holders and
underwriter(s), if any, may reasonably request to have included therein, including, without
limitation, information relating to the “Plan of Distribution” of the Transfer Restricted
Securities, information with respect to the principal amount of Transfer Restricted
Securities being sold to such underwriter(s), the purchase price being paid therefor and any
other terms of the offering of the Transfer Restricted Securities to be sold in such
offering; and make all required filings of such Prospectus supplement or post-effective
amendment as soon as practicable after the Company is notified of the matters to be
incorporated in such Prospectus supplement or post-effective amendment;

     (viii) cause the Transfer Restricted Securities covered by such Registration Statement
to be rated with the appropriate rating agencies, if so requested by the Holders of a
majority in aggregate principal amount of Securities covered thereby or the underwriter(s),
if any;

     (ix) furnish to each selling Holder and each of the underwriter(s), if any, without
charge, at least one copy of such Registration Statement, as first filed with the

10

 

Commission, and of each amendment thereto, including financial statements and
schedules, all documents incorporated by reference therein and all exhibits (including
exhibits incorporated therein by reference);

     (x) deliver to each selling Holder and each of the underwriter(s), if any, without
charge, as many copies of the Prospectus (including each preliminary prospectus) and any
amendment or supplement thereto as such Persons reasonably may request; the Company and the
Guarantors hereby consent to the use of the Prospectus and any amendment or supplement
thereto by each of the selling Holders and each of the underwriter(s), if any, in connection
with the offering and the sale of the Transfer Restricted Securities covered by the
Prospectus or any amendment or supplement thereto;

     (xi) enter into, and cause the Guarantors to enter into, such agreements (including an
underwriting agreement), and make, and cause the Guarantors to make, such representations
and warranties, and take all such other actions in connection therewith in order to expedite
or facilitate the disposition of the Transfer Restricted Securities pursuant to any
Registration Statement contemplated by this Agreement, all to such extent as may be
reasonably requested by any Initial Purchaser or by any Holder of Transfer Restricted
Securities or underwriter in connection with any sale or resale pursuant to any Registration
Statement contemplated by this Agreement; and whether or not an underwriting agreement is
entered into and whether or not the registration is an Underwritten Registration, the
Company and the Guarantors shall:

     (A) furnish to each Initial Purchaser, each selling Holder and each
underwriter, if any, in such substance and scope as they may request and as are
customarily made by issuers to underwriters in primary underwritten offerings, upon
the date of the Consummation of the Exchange Offer and, if applicable, the
effectiveness of the Shelf Registration Statement:

     (1) a certificate, dated the date of Consummation of the Exchange
Offer or the date of effectiveness of the Shelf Registration Statement, as
the case may be, signed by (y) the President or any Vice President and (z) a
principal financial or accounting officer of each of the Company and the
Guarantors, confirming, as of the date thereof, the matters set forth in
paragraphs (i), (ii) and (iii) of Section 5 (e) of the Purchase Agreement
and such other matters as such parties may reasonably request;

     (2) opinions, dated the date of Consummation of the Exchange Offer or
the date of effectiveness of the Shelf Registration Statement, as the case
may be, of counsel for the Company and the Guarantors and of counsel of the
Company and the Guarantors, covering such matters as such parties may
reasonably request, and in any event including a statement to the effect
counsel for the Company and the Guarantors has participated in conferences
with officers and other representatives of the Company, representatives of
the independent public accountants for the Company, the Initial Purchasers’
representatives and the Initial Purchasers’ counsel in connection with the
preparation of such

11

 

Registration Statement and the related Prospectus and have considered
the matters required to be stated therein and the statements contained
therein, although such counsel has not independently verified the accuracy,
completeness or fairness of such statements; and that such counsel advises
that, on the basis of the foregoing (relying as to materiality to a large
extent upon facts provided to such counsel by officers and other
representatives of the Company and without independent check or
verification), no facts came to such counsel’s attention that caused such
counsel to believe that the applicable Registration Statement, at the time
such Registration Statement or any post-effective amendment thereto became
effective, and, in the case of the Exchange Offer Registration Statement, as
of the date of Consummation, contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, or that the
Prospectus contained in such Registration Statement as of its date and, in
the case of the opinion dated the date of Consummation of the Exchange
Offer, as of the date of Consummation, contained an untrue statement of a
material fact or omitted to state a material fact necessary in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading. Without limiting the foregoing, such counsel may
state further that such counsel assumes no responsibility for, and has not
independently verified, the accuracy, completeness or fairness of the
financial statements, notes and schedules and other financial data included
in any Registration Statement contemplated by this Agreement or the related
Prospectus; and

     (3) a customary comfort letter, dated as of the date of Consummation
of the Exchange Offer or the date of effectiveness of the Shelf Registration
Statement, as the case may be, from the Company’s independent accountants,
in the customary form and covering matters of the type customarily covered
in comfort letters by underwriters in connection with primary underwritten
offerings, and affirming the matters set forth in the comfort letters
delivered pursuant to Sections 5(a) of the Purchase Agreement, without
exception;

     (B) set forth in full or incorporate by reference in the underwriting
agreement, if any, the indemnification provisions and procedures of Section 8 hereof
with respect to all parties to be indemnified pursuant to said Section; and

     (C) deliver such other documents and certificates as may be reasonably
requested by such parties to evidence compliance with clause (A) above and with any
customary conditions contained in the underwriting agreement or other agreement
entered into by the Company or the Guarantors pursuant to this clause (xi), if any.

     If at any time the representations and warranties of the Company and the Guarantors
contemplated in clause (A)(1) above cease to be true and correct, the

12

 

Company or the Guarantors shall so advise the Initial Purchasers and the
underwriter(s), if any, and each selling Holder promptly and, if requested by such Persons,
shall confirm such advice in writing;

     (xii) prior to any public offering of Transfer Restricted Securities, cooperate with
the selling Holders, the underwriter(s), if any, and their respective counsel in connection
with the registration and qualification of the Transfer Restricted Securities under the
securities or Blue Sky laws of such jurisdictions as the selling Holders or underwriter(s)
may request and do any and all other acts or things necessary or advisable to enable the
disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf
Registration Statement; provided, however, that neither the Company nor any Guarantor shall
be required to register or qualify as a foreign corporation where it is not then so
qualified or to take any action that would subject it to the service of process in suits or
to taxation, other than as to matters and transactions relating to the Registration
Statement, in any jurisdiction where it is not then so subject;

     (xiii) shall issue, upon the request of any Holder of Initial Securities covered by
the Shelf Registration Statement, Exchange Securities of the same series, having an
aggregate principal amount equal to the aggregate principal amount of Initial Securities
surrendered to the Company by such Holder in exchange therefor or being sold by such Holder;
such Exchange Securities to be registered in the name of such Holder or in the name of the
purchasers of such Securities, as the case may be; in return, the Initial Securities held by
such Holder shall be surrendered to the Company for cancellation;

     (xiv) cooperate with the selling Holders and the underwriter(s), if any, to facilitate
the timely preparation and delivery of certificates representing Transfer Restricted
Securities to be sold and not bearing any restrictive legends; and enable such Transfer
Restricted Securities to be in such denominations and registered in such names as the
Holders or the underwriter(s), if any, may request at least two business days prior to any
sale of Transfer Restricted Securities made by such underwriter(s);

     (xv) use its commercially reasonable best efforts to cause the Transfer Restricted
Securities covered by such Registration Statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the seller or
sellers thereof or the underwriter(s), if any, to consummate the disposition of such
Transfer Restricted Securities, subject to the proviso contained in clause (viii) above;

     (xvi) if any fact or event contemplated by clause (c)(iii)(D) above shall exist or
have occurred, prepare a supplement or post-effective amendment to such Registration
Statement or related Prospectus or any document incorporated therein by reference or file
any other required document so that, as thereafter delivered to the purchasers of Transfer
Restricted Securities, the Prospectus will not contain an untrue statement of a material
fact or omit to state any material fact necessary to make the statements therein not
misleading;

     (xvii) provide a CUSIP number for all Transfer Restricted Securities not later than
the effective date of such Registration Statement and provide the Trustee under the

13

 

Indenture with printed certificates for the Transfer Restricted Securities which are in
a form eligible for deposit with the Depositary Trust Company;

     (xviii) cooperate and assist in any filings required to be made with the FINRA and in
the performance of any due diligence investigation by any underwriter (including any
“qualified independent underwriter”) that is required to be retained in accordance with the
rules and regulations of the FINRA, and use its commercially reasonable best efforts to
cause such Registration Statement to become effective and approved by such governmental
agencies or authorities as may be necessary to enable the Holders selling Transfer
Restricted Securities to consummate the disposition of such Transfer Restricted Securities;

     (xix) otherwise use its commercially reasonable best efforts to comply with all
applicable rules and regulations of the Commission, and make generally available to its
security holders, as soon as practicable, a consolidated earnings statement meeting the
requirements of Rule 158 (which need not be audited) for the twelve-month period (A)
commencing at the end of any fiscal quarter in which Transfer Restricted Securities are sold
to underwriters in a firm or commercially reasonable best efforts Underwritten Offering or
(B) if not sold to underwriters in such an offering, beginning with the first month of the
Company’s first fiscal quarter commencing after the effective date of such Registration
Statement;

     (xx) cause each Indenture to be qualified under the Trust Indenture Act not later than
the effective date of the first Registration Statement required by this Agreement, and, in
connection therewith, cooperate with the Trustee and the Holders of Securities to effect
such changes to the Indenture as may be required for such Indenture to be so qualified in
accordance with the terms of the Trust Indenture Act; and execute and use its commercially
reasonable best efforts to cause the Trustee to execute, all documents that may be required
to effect such changes and all other forms and documents required to be filed with the
Commission to enable such Indenture to be so qualified in a timely manner;

     (xxi) cause all Transfer Restricted Securities covered by the Registration Statement
to be listed on each securities exchange on which similar securities issued by the Company
are then listed if requested by the Holders of a majority in aggregate principal amount of
Initial Securities or the managing underwriter(s), if any; and

     (xxii) provide promptly to each Holder upon request each document filed with the
Commission pursuant to the requirements of Section 13 and Section 15 of the Exchange Act.

     Each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of any
notice from the Company of the existence of any fact of the kind described in Section 6(c)(iii)(D)
hereof, such Holder will forthwith discontinue disposition of Transfer Restricted Securities
pursuant to the applicable Registration Statement until such Holder’s receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 6(c)(xvi) hereof, or until it is advised
in writing (the “Advice”) by the Company that the use of the Prospectus may be resumed, and has
received copies of any additional or supplemental filings that are

14

 

incorporated by reference in the Prospectus. If so directed by the Company, each Holder will
deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then
in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that
was current at the time of receipt of such notice. In the event the Company shall give any such
notice, the time period regarding the effectiveness of such Registration Statement set forth in
Section 3 or 4 hereof, as applicable, shall be extended by the number of days during the period
from and including the date of the giving of such notice pursuant to Section 6(c)(iii)(D) hereof to
and including the date when each selling Holder covered by such Registration Statement shall have
received the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xvi)
hereof or shall have received the Advice; however, no such extension shall be taken into account in
determining whether Additional Interest is due pursuant to Section 5 hereof or the amount of such
Additional Interest, it being agreed that the Company’s option to suspend use of a Registration
Statement pursuant to this paragraph shall be treated as a Registration Default for purposes of
Section 5.

     Section 7. Registration Expenses.

     (a) All expenses incident to the Company’s and the Guarantors’ performance of or compliance
with this Agreement will be borne by the Company or the Guarantors, regardless of whether a
Registration Statement becomes effective, including without limitation: (i) all registration and
filing fees and expenses (including filings made by any Initial Purchaser or Holder with the FINRA
(and, if applicable, the fees and expenses of any “qualified independent underwriter” and its
counsel that may be required by the rules and regulations of the FINRA)); (ii) all fees and
expenses of compliance with federal securities and state Blue Sky or securities laws; (iii) all
expenses of printing (including printing certificates for the Exchange Securities to be issued in
the Exchange Offer and printing of Prospectuses), messenger and delivery services and telephone;
(iv) all fees and disbursements of counsel for the Company, the Guarantors and, subject to Section
7(b) below, the Holders of Transfer Restricted Securities; (v) all application and filing fees in
connection with listing the Exchange Securities on a national securities exchange or automated
quotation system pursuant to the requirements thereof; and (vi) all fees and disbursements of
independent certified public accountants of the Company and the Guarantors (including the expenses
of any special audit and comfort letters required by or incident to such performance).

     The Company will, in any event, bear its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal or accounting duties), the
expenses of any annual audit and the fees and expenses of any Person, including special experts,
retained by the Company.

     (b) In connection with any Registration Statement required by this Agreement (including,
without limitation, the Exchange Offer Registration Statement and the Shelf Registration
Statement), the Company will reimburse the Initial Purchasers and the Holders of Transfer
Restricted Securities being tendered in the Exchange Offer and/or resold pursuant to the “Plan of
Distribution” contained in the Exchange Offer Registration Statement or registered pursuant to the
Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more
than one counsel, who shall be Davis Polk & Wardwell or such other

15

 

counsel as may be chosen by the Holders of a majority in principal amount of the Transfer
Restricted Securities for whose benefit such Registration Statement is being prepared.

     Section 8. Indemnification.

     (a) The Company agrees and the Guarantors, jointly and severally, agree to indemnify and hold
harmless (i) each Holder and (ii) each person, if any, who controls (within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the persons referred
to in this clause (ii) being hereinafter referred to as a “controlling person”) and (iii) the
respective officers, directors, partners, employees, representatives and agents of any Holder or
any controlling person (any person referred to in clause (i), (ii) or (iii) may hereinafter be
referred to as an “Indemnified Holder”), to the fullest extent lawful, from and against any and all
losses, claims, damages, liabilities, judgments, actions and expenses (including without limitation
and as incurred, reimbursement of all reasonable costs of investigating, preparing, pursuing,
settling, compromising, paying or defending any claim or action, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, including the reasonable
fees and expenses of counsel to any Indemnified Holder), joint or several, directly or indirectly
caused by, related to, based upon, arising out of or in connection with any untrue statement or
alleged untrue statement of a material fact contained in any Registration Statement or Prospectus
(or any amendment or supplement thereto), or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages, liabilities or expenses are caused by
an untrue statement or omission or alleged untrue statement or omission that is made in reliance
upon and in conformity with information relating to any of the Holders furnished in writing to the
Company by any of the Holders expressly for use therein. This indemnity agreement shall be in
addition to any liability which the Company may otherwise have.

     In case any action or proceeding (including any governmental or regulatory investigation or
proceeding) shall be brought or asserted against any of the Indemnified Holders with respect to
which indemnity may be sought against the Company or the Guarantors, such Indemnified Holder (or
the Indemnified Holder controlled by such controlling person) shall promptly notify the Company and
the Guarantors in writing (provided that the failure to give such notice shall not relieve the
Company or the Guarantors of their respective obligations pursuant to this Agreement). Such
Indemnified Holder shall have the right to employ its own counsel in any such action and the fees
and expenses of such counsel shall be paid, as incurred, by the Company and the Guarantors
(regardless of whether it is ultimately determined that an Indemnified Holder is not entitled to
indemnification hereunder). The Company and the Guarantors shall not, in connection with any one
such action or proceeding or separate but substantially similar or related actions or proceedings
in the same jurisdiction arising out of the same general allegations or circumstances, be liable
for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to
any local counsel) at any time for such Indemnified Holders, which firm shall be designated by the
Holders. The Company shall be liable for any settlement of any such action or proceeding effected
with the Company’s prior written consent, which consent shall not be withheld unreasonably, and the
Company agrees to indemnify and hold harmless any Indemnified Holder from and against any loss,
claim, damage, liability or expense by reason of any settlement of any action effected with the
written consent of the Company. The Company shall not, without the prior written consent of each
Indemnified Holder, settle or compromise or

16

 

consent to the entry of judgment in or otherwise seek to terminate any pending or threatened
action, claim, litigation or proceeding in respect of which indemnification or contribution may be
sought hereunder (whether or not any Indemnified Holder is a party thereto), unless such
settlement, compromise, consent or termination (i) includes an unconditional release of each
Indemnified Holder from all liability arising out of such action, claim, litigation or proceeding
and (ii) does not include any statements as to or any findings of fault, culpability or failure to
act by or on behalf of any Indemnified Holder.

     (b) Each Holder of Transfer Restricted Securities agrees, severally and not jointly, to
indemnify and hold harmless the Company, the Guarantors and their respective directors, officers of
the Company and the Guarantors who sign a Registration Statement, and any person controlling
(within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the
Company, and the respective officers, directors, partners, employees, representatives and agents of
each such person, to the same extent as the foregoing indemnity from the Company and the Guarantors
to each of the Indemnified Holders, but only with respect to claims and actions based on
information relating to such Holder furnished in writing by such Holder expressly for use in any
Registration Statement. In case any action or proceeding shall be brought against the Company, the
Guarantors or their respective directors or officers or any such controlling person in respect of
which indemnity may be sought against a Holder of Transfer Restricted Securities, such Holder shall
have the rights and duties given the Company, the Guarantors or their respective directors or
officers or such controlling person shall have the rights and duties given to each Holder by the
preceding paragraph.

     (c) If the indemnification provided for in this Section 8 is unavailable to an indemnified
party under Section 8(a) or Section 8(b) hereof (other than by reason of exceptions provided in
those Sections) in respect of any losses, claims, damages, liabilities, judgments, actions or
expenses referred to therein, then each applicable indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages, liabilities or expenses in such proportion as is
appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one
hand, and the Holders, on the other hand, from the Initial Placement (which in the case of the
Issuer shall be deemed to be equal to the total gross proceeds from the Initial Placement as set
forth on the cover page of the Offering Memorandum), the amount of Additional Interest which did
not become payable as a result of the filing of the Registration Statement resulting in such
losses, claims, damages, liabilities, judgments actions or expenses, and such Registration
Statement, or if such allocation is not permitted by applicable law, the relative fault of the
Company and the Guarantors on the one hand, and of the Indemnified Holder, on the other hand, in
connection with the statements or omissions which resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations. The relative
fault of the Company and the Guarantors on the one hand and of the Indemnified Holder on the other
shall be determined by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a material fact relates
to information supplied by the Company and the Guarantors or by the Indemnified Holder and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to
the limitations set forth in the second paragraph of Section 8(a), any legal or other fees or

17

 

expenses reasonably incurred by such party in connection with investigating or defending any
action or claim.

     The Company, the Guarantors and each Holder of Transfer Restricted Securities agree that it
would not be just and equitable if contribution pursuant to this Section 8(c) were determined by
pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any
other method of allocation which does not take account of the equitable considerations referred to
in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, liabilities or expenses referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set forth above, any
legal or other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the provisions of this
Section 8, none of the Holders (and their related Indemnified Holders) shall be required to
contribute, in the aggregate, any amount in excess of the amount by which the total discount
received by such Holder with respect to the Initial Securities exceeds the amount of any damages
which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to
contribute pursuant to this Section 8(c) are several in proportion to the respective principal
amount of Initial Securities held by each of the Holders hereunder and not joint.

     Section 9. Rule 144A. Each of the Company and the Guarantors hereby agrees with
each Holder, for so long as any Transfer Restricted Securities remain outstanding, to make
available to any Holder or beneficial owner of Transfer Restricted Securities in connection with
any sale thereof and any prospective purchaser of such Transfer Restricted Securities from such
Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in
order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A.

     Section 10. Participation In Underwritten Registrations. No Holder may participate
in any Underwritten Registration hereunder unless such Holder (a) agrees to sell such Holder’s
Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by
the Persons entitled hereunder to approve such arrangements and (b) completes and executes all
reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up
letters and other documents required under the terms of such underwriting arrangements.

     Section 11. Selection Of Underwriters. The Holders of Transfer Restricted
Securities covered by the Shelf Registration Statement who desire to do so may sell such Transfer
Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the
investment banker or investment bankers and manager or managers that will administer the offering
will be selected by the Holders of a majority in aggregate principal amount of the Transfer
Restricted Securities included in such offering; provided that such investment bankers and managers
must be reasonably satisfactory to the Company.

     Section 12. Miscellaneous.

18

 

     (a) Remedies. The Company and the Guarantors each hereby agree that monetary damages would
not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of
this Agreement and hereby agree to waive the defense in any action for specific performance that a
remedy at law would be adequate.

     (b) No Inconsistent Agreements. The Company and the Guarantors will not, on or after the
date of this Agreement enter into any agreement with respect to their securities that is
inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with
the provisions hereof. Neither the Company nor the Guarantors have entered into any agreement
granting any registration rights with respect to its securities to any Person. The rights granted
to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights
granted to the holders of the Company’s securities under any agreement in effect on the date
hereof.

     (c) Adjustments Affecting the Securities. The Company and the Guarantors will not take any
action, or permit any change to occur, with respect to the Securities that would materially and
adversely affect the ability of the Holders to Consummate any Exchange Offer.

     (d) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or
supplemented, and waivers or consents to or departures from the provisions hereof may not be given
