instrument acknowledged to him the execution thereof. Where such execution is by a signer acting

record date, only the Holders on such date (or their duly designated proxies) shall be entitled to
give or take, or vote on, the relevant action.

     The ownership of Notes shall be proved by the Register.

     Any request, demand, authorization, direction, notice, consent, waiver or other action of the
Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note

respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance
thereon, whether or not notation of such action is made upon such Note.

event, at such Holder’s address as it appears in the Register, not later than the latest date (if
any), and not earlier than the earliest date (if any), prescribed for the giving of such notice.
In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor
any defect in

13

 

any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either before or after the
event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall
be filed with the Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

     In case by reason of the suspension of regular mail service or by reason of any other cause it
shall be impracticable to give such notice by mail, then such notification as shall be made with
the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Convertible Senior Notes due 2016 (the “Notes”), initially limited in aggregate principal amount to
$135,000,000, which amount may from time to time be increased or decreased by adjustments made on
the records of the Trustee, as Custodian for the Depositary, in accordance with the rules and
procedures of the Depositary and in accordance with the below referred Indenture) all issued or to
be issued under and pursuant to an Indenture dated as of July 22, 2011 (the “Indenture”) among the
Company, the guarantors named on the signature pages thereof (the “Guarantors”), and Wells Fargo
Bank, National Association, as Trustee (the “Trustee”), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights, limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the Company, the Guarantors
and the Holders of the Notes. The Indenture provides that Additional Notes may be issued
thereunder, if certain conditions are met.

     Interest. The Notes will bear interest at a rate of 5.5% per year. Interest on the
Notes will accrue from, and including, July 22, 2011, or from the most recent date to which
interest has been paid or duly provided for. Interest will be payable semiannually in arrears on
each Interest Payment Date, beginning January 15, 2012. Pursuant to Section 9.03 of the Indenture,
in certain circumstances, the Holders of Notes shall be entitled to receive Additional Interest.

     Interest will be paid to the Person in whose name a Note is registered at the Close of
Business on the January 1 or July 1 (whether or not such date is a Business Day), as the case may
be, immediately preceding the relevant Interest Payment Date. Interest on the Notes will be
computed on the basis of a 360-day year composed of twelve 30-day months.

18

 

     Interest will cease to accrue on a Note upon its stated maturity, conversion or repurchase in
connection with a Fundamental Change.

     Ranking. The Notes constitute a general unsecured and unsubordinated obligation of
the Company.

     Guarantees. The payment by the Company of the principal of, interest and Additional
Interest, if any, on the Notes is fully and unconditionally guaranteed on a joint and several
senior unsecured basis by each of the Guarantors to the extent set forth in the Indenture.

     No Optional Redemption. The Notes are not redeemable by the Company prior to their
stated maturity date. No sinking fund is provided for the Notes.

     Purchase at the Option of the Holder Upon a Fundamental Change. Subject to the terms
and conditions of the Indenture, the Company shall become obligated, at the option of the Holder,
to repurchase the Notes if a Fundamental Change occurs at any time prior to the Maturity Date at
100% of the Principal Amount together with accrued and unpaid interest to, but excluding, the
Fundamental Change Purchase Date, which amount will be paid in cash.

     Withdrawal of Fundamental Change Purchase Notice. Holders have the right to withdraw,
in whole or in part, any Fundamental Change Purchase Notice by delivering to the Paying Agent a
written notice of withdrawal in accordance with the provisions of the Indenture. The right to
withdraw the Fundamental Change Purchase Notice will terminate at the Close of Business on the
Business Day immediately preceding the relevant Fundamental Change Purchase Date.

     Payment of Fundamental Change Purchase Price. If money sufficient to pay the
Fundamental Change Purchase Price of all Notes or portions thereof to be purchased on a Fundamental
Change Purchase Date is deposited with the Paying Agent on the Fundamental Change Purchase Date,
such Notes will cease to be outstanding and interest will cease to accrue on such Notes (or
portions thereof) immediately after the Close of Business on such Fundamental Change Purchase Date,
and the Holder thereof shall have no other rights as such (other than the right to receive the
Fundamental Change Purchase Price, upon surrender of such Note).

     Conversion. Subject to and upon compliance with the provisions of the Indenture
(including without limitation the conditions of conversion of this Note set forth in Article 7
thereof), the Holder hereof has the right, at its option, to convert the Principal Amount hereof or
any portion of such principal which is $1,000 or an integral multiple of $1,000 in excess thereof,
into shares of Common Stock at the Applicable Conversion Rate. The Conversion Rate is initially
54.0190 shares of Common Stock per $1,000 Principal Amount of Notes (equivalent to an initial
Conversion Price of approximately $18.51), subject to adjustment in certain events described in the
Indenture. Upon conversion, the Company will deliver shares of Common Stock as set forth in the
Indenture. No fractional shares will be issued upon any conversion, but a payment in cash will be
made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be
issuable upon the surrender of any Notes for conversion. Notes in respect of which a Holder is
exercising its right to require repurchase on a Fundamental Change

19

 

Purchase Date may be converted only if such Holder withdraws the related election to exercise
such right in accordance with the terms of the Indenture.

     In the event of a deposit or withdrawal of an interest in this Note, including an exchange,
transfer, repurchase or conversion of this Note in part only, the Trustee, as custodian of the
Depositary, shall make an adjustment on its records to reflect such deposit or withdrawal in
accordance with the rules and procedures of the Depositary.

     Acceleration of Maturity. Subject to certain exceptions in the Indenture, if an Event
of Default shall occur and be continuing, the Principal Amount plus interest through such date on
all the Notes may be declared due and payable in the manner and with the effect provided in the
Indenture.

     Supplemental Indentures with Consent of Holders; Waiver of Past Defaults. The
Indenture permits, with certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the Holders of the
Notes under the Indenture at any time by the Company, the Guarantors and the Trustee with the
consent of the Holders of not less than a majority in aggregate Principal Amount of the outstanding
Notes. The Indenture also contains provisions permitting the Holders of specified percentages in
aggregate Principal Amount of the outstanding Notes, on behalf of the Holders of all the Notes, to
waive compliance by the Company with certain provisions of the Indenture and certain past Defaults
under the Indenture and their consequences. Any such consent or waiver by the Holder of any
provision of or applicable to this Note shall be conclusive and binding upon such Holder and upon
all future Holders of this Note and of any Note issued upon the registration of transfer hereof or
in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Note.

     Registration of Transfer and Exchange. As provided in the Indenture and subject to
certain limitations therein set forth, the transfer of this Note is registrable in the Register,
upon surrender of this Note for registration of transfer at the office or agency of the Company in
the United States, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Registrar duly executed by, the Holder hereof or his attorney
duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and
for the same aggregate Principal Amount, will be issued to the designated transferee or
transferees.

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

     Prior to due presentment of this Note for registration of transfer, the Company, the

to Sections 3.05, 3.06, 3.07, 3.08, 3.09, 3.11, 3.12, 8.05 or 14.06. Initial Notes in an aggregate

25

 

Principal Amount of $135,000,000 shall be issued on the date hereof upon the Company’s compliance
with Section 3.04. The Company may, from time to time after the execution of this Indenture,
execute and deliver to the Trustee for authentication Additional Notes of an unlimited aggregate
principal amount, and the Trustee shall thereupon authenticate and deliver said Additional Notes to
or upon the written order of the Company, without any further action by the Company hereunder;
provided, however, that (1) if any such Additional Notes are not fungible with the Initial Notes
for U.S. federal income tax purposes, any such Additional Notes will have a separate CUSIP number;
(2) such Additional Notes must be issued pursuant to the same terms (other than the offering price)
and as the Initial Notes; and (3) the Trustee must receive an Officers’ Certificate to the effect
that such issuance of Additional Notes complies with the provisions of this Indenture, including
each provision of this paragraph.

     The Notes shall be known and designated as the “5.5% Convertible Senior Notes due 2016” of the
Company. The Principal Amount shall be payable on the Maturity Date.

     The Principal Amount of Physical Notes shall be payable at the office of the Paying Agent in
the City and State of New York and at any other office or agency maintained by the Company for such
purpose. Interest on Physical Notes will be payable (i) to Holders having an aggregate Principal
Amount of $1,000,000 or less of Notes, by check mailed to such Holders at the address set forth in
the Register and (ii) to Holders having an aggregate Principal Amount of more than $1,000,000 of
Notes, either by check mailed to such Holders or, upon application by a Holder to the Registrar not
later than the relevant Regular Record Date for such interest payment, by wire transfer in
immediately available funds to such Holder’s account within the United States, which application
shall remain in effect until the Holder notifies the Registrar to the contrary in writing. The
Company will pay principal of, and interest on, Global Notes in immediately available funds to The
Depository Trust Company or its nominee, as the case may be, as the registered holder of such
Global Note, on each Interest Payment Date, Fundamental Change Purchase Date or other payment date,
as the case may be.

     Any Notes repurchased by the Company will be cancelled and no longer outstanding hereunder.

     Section 3.02 Ranking. The Notes constitute a general unsecured and unsubordinated
obligation of the Company.

     Section 3.03 Denominations. The Notes shall be issuable only in registered form without
coupons and in minimum denominations of $1,000 and any integral multiple of $1,000 in excess
thereof.

     Section 3.04 Execution, Authentication, Delivery and Dating. The Notes shall be executed
on behalf of the Company by its Chief Executive Officer, its President, its Chief Financial Officer
or any of its Vice Presidents

     Notes bearing the manual or facsimile signatures of individuals who were at any time the
proper officers of the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and delivery of such Notes or
did not hold such offices at the date of such Notes.

26

 

     Subject to Section 3.01, 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, together with a Company Order for the authentication and delivery of such Notes.
The Company Order shall specify the amount of Notes to be authenticated, and shall further specify
the amount of such Notes to be issued as Global Notes or as Physical Notes. The Trustee in
accordance with such Company Order shall authenticate and deliver such Notes as in this Indenture
provided and not otherwise.

     Each Note shall be dated the date of its authentication.

     No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for
any purpose unless there appears on such Note a certificate of authentication substantially in the
form provided for herein executed by the Trustee by manual signature, and such certificate upon any
Note shall be conclusive evidence, and the only evidence, that such Note has been duly
authenticated and delivered hereunder.

     Section 3.05 Temporary Notes. Pending the preparation of definitive Notes, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Notes that
are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued
and with such appropriate insertions, omissions, substitutions and other variations as the officers
executing such Notes may determine, as evidenced by their execution of such Notes; provided, that
any such temporary Notes shall bear legends on the face of such Notes as set forth in Section 2.02.

     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 shall be
exchangeable for definitive Notes upon surrender of the temporary Notes at any office or agency of
the Company designated pursuant to Section 4.02, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Notes, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like Principal Amount of Physical Notes of
authorized denominations. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits under this Indenture as Physical Notes.

     Section 3.06 Registration; Registration of Transfer and Exchange.

     (a) The Company shall cause to be kept at the applicable Corporate Trust Office of the Trustee
a register (the register maintained in such office and in any other office or agency designated
pursuant to Section 4.02 being herein sometimes collectively referred to as the “Register”) in
which, subject to such reasonable regulations as it may prescribe, the Company shall provide for
the registration of Notes and of transfers of Notes. The Trustee is hereby appointed “Registrar”
(the “Registrar”) for the purpose of registering Notes and transfers of Notes as herein provided.

     Upon surrender for registration of transfer of any Note at an office or agency of the Company
designated pursuant to Section 4.02 for such purpose, the Company shall execute, and the Trustee
shall authenticate and deliver, in the name of the designated transferee or transferees,

27

 

one or more new Notes of any authorized denominations and of a like aggregate Principal Amount
and tenor, each such Note bearing such restrictive legends as may be required by this Indenture
(including Sections 2.02, 3.07 and 3.11).

     At the option of the Holder and subject to the other provisions of Section 3.07 and to Section
3.11, Notes may be exchanged for other Notes of any authorized denominations and of a like
aggregate Principal Amount and tenor, upon surrender of the Notes to be exchanged at such office or
agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is entitled
to receive.

     All Notes issued upon any registration of transfer or exchange of Notes shall be the valid
obligations of the Company, evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Notes surrendered upon such registration of transfer or exchange.

     Every Note presented or surrendered for registration of transfer or for exchange shall (if so
required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument
of transfer in form satisfactory to the Company and the Registrar duly executed, by the Holder
thereof or his attorney duly authorized in writing. As a condition to the registration of transfer
of any Restricted Notes, the Company or the Trustee may require evidence satisfactory to them as to
the compliance with the restrictions set forth in the legend on such Notes.

     No service charge shall be made for any registration of transfer or exchange of Notes, but the
Company and the Registrar may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration of transfer or exchange
of Notes, other than exchanges pursuant to Section 3.05 not involving any transfer.

     Neither the Company nor the Registrar shall be required to exchange or register a transfer of
any Note in the circumstances set forth in Section 3.11(a)(iv).

     (b) Neither any members of, or participants in, the Depositary (collectively, the “Agent
Members”) nor any other Persons on whose behalf any Agent Member may act shall have any rights
under this Indenture with respect to any Global Note registered in the name of the Depositary or
any nominee thereof, or under any such Global Note, and the Depositary or such nominee, as the case
may be, may be treated by the Company, the Guarantors, the Trustee and any agent of the Company,
the Guarantors or the Trustee as the absolute owner and Holder of such Global Note for all purposes
whatsoever. The Trustee shall have no responsibility or obligation to any Agent Members or any
other Person on whose behalf Agent Members may act with respect to (i) any ownership interests in
the Global Note, (ii) the accuracy of the records of the Depositary or its nominee, (iii) any
notice required hereunder or (iv) any payments under or with respect to the Global Note.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the Guarantors, the
Trustee or any agent of the Company, the Guarantors or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary or such nominee, as
the case may be, or impair, as between the Depositary, its Agent Members and any other Person on
whose behalf an Agent Member may act, the operation of customary practices of such Persons
governing the exercise of the rights of a Holder of any Note. The registered Holder of a Global
Note may grant proxies and otherwise authorize any

28

 

Person, including Agent Members and Persons that may hold interests through Agent Members, to
take any action that a Holder is entitled to take under this Indenture or the Notes.

     Section 3.07 Transfer Restrictions.

     (a) Restricted Notes.

     (i) Every Note (and all securities issued in exchange therefor or substitution thereof,
except any shares of Common Stock issued upon conversion thereof) that bears, or that is
required under this Section 3.07 to bear, the Restricted Notes Legend will be deemed to be a
“Restricted Note.” Each Restricted Note will be subject to the restrictions on transfer set
forth in this Indenture (including in the Restricted Notes Legend) and will bear the
restricted CUSIP number for the Notes unless such restrictions on transfer are eliminated or
otherwise waived by written consent of the Company, and each Holder of a Restricted Note, by
such Holder’s acceptance of such Restricted Note, will be deemed to be bound by the
restrictions on transfer applicable to such Restricted Note.

     (ii) Until the Resale Restriction Termination Date, any Note (or any security issued in
exchange therefor or substitution thereof, except any shares of Common Stock issued upon the
conversion thereof) will bear the Restricted Notes Legend unless:

     (A) such Note, since last held by the Company or an affiliate of the Company
(within the meaning of Rule 144), if ever, was transferred (1) to a Person other
than (x) the Company or (y) an affiliate of the Company (within the meaning of Rule
144) or a Person that was an affiliate of the Company within the three months
immediately preceding such transfer and (2) pursuant to a registration statement
that was effective under the Securities Act at the time of such transfer;

     (B) such Note was transferred (1) to a Person other than (x) the Company or (y)
an affiliate of the Company (within the meaning of Rule 144) or a Person that was an
affiliate of the Company within the three months immediately preceding such transfer
and (2) pursuant to the exemption from registration provided by Rule 144 or any
similar provision then in force under the Securities Act; or

     (C) the Company delivers written notice to the Trustee and the Registrar
stating that the Restricted Notes Legend may be removed from such Note.

     (iii) In addition, until the Resale Restriction Termination Date:

     (A) no transfer of any Note will be registered by the Registrar prior to the
Resale Restriction Termination Date unless the transferring Holder delivers the form
of assignment set forth on the Note, with the appropriate box checked, to the
Trustee; and

29

 

     (B) the Registrar will not register any transfer of any Note that is a
Restricted Note to a Person that is an affiliate of the Company or has been an
affiliate of the Company (within the meaning of Rule 144) within the three months
immediately preceding the date of such proposed transfer.

     (iv) On and after the Resale Restriction Termination Date, any Note (or any security
issued in exchange therefor or substitution thereof, except any shares of Common Stock
issued upon the conversion thereof) will bear the Restricted Notes Legend at any time the
Company reasonably determinates that, to comply with law, such Note (or such securities
issued in exchange for or substitution of a Note) must bear the Restricted Notes Legend.

     (b) Restricted Stock.

     (i) Every share of Common Stock that bears, or that is required under this Section 3.07
to bear, the Restricted Stock Legend will be deemed to be “Restricted Stock.” Each share of
Restricted Stock will be subject to the restrictions on transfer set forth in this Indenture
(including in the Restricted Stock Legend) and will bear a restricted CUSIP number unless
such restrictions on transfer are eliminated or otherwise waived by written consent of the
Company, and each Holder of Restricted Stock, by such Holder’s acceptance of Restricted
Stock, will be deemed to be bound by the restrictions on transfer applicable to such
Restricted Stock.

     (ii) Until the Resale Restriction Termination Date, any share of Common Stock issued
upon the conversion of a Note will be issued in definitive form and will bear the Restricted
Stock Legend unless:

     (A) such share of Common Stock was transferred (1) to a Person other than (x)
the Company or (y) an affiliate of the Company (within the meaning of Rule 144) or a
Person that was an affiliate of the Company within the three months immediately
preceding such transfer and (2) pursuant to a registration statement that was
effective under the Securities Act at the time of such conversion;

     (B) such share of Common Stock was transferred (1) to a Person other than (x)
the Company or (y) an affiliate of the Company (within the meaning of Rule 144) or a
Person that was an affiliate of the Company within the three months immediately
preceding such transfer and (2) pursuant to the exemption from registration provided
by Rule 144 or any similar provision then in force under the Securities Act;

     (C) such Note, regardless of whether bearing the Restricted Notes Legend, was
not, at the time of its conversion, required to bear the Restricted Notes Legend
pursuant to Section 3.07(a) and such Common Stock was issued to a Person other than
(1) the Company or (2) an affiliate of the Company; or

30

 

     (D) the Company delivers written notice to the Trustee, the Registrar and the
transfer agent for the Common Stock stating that such share of Common Stock need not
bear the Restricted Stock Legend.

     (iii) On and after the Resale Restriction Termination Date, any share of Common Stock
will be issued in definitive form and will bear the Restricted Stock Legend at any time the
Company reasonably determinates that, to comply with law, such share of Common Stock must
bear the Restricted Stock Legend.

     (c) As used in this Section 3.07, the term “transfer” means any sale, pledge, transfer, loan,
hypothecation or other disposition whatsoever of any Restricted Note, any interest therein or any
Restricted Stock.

     Section 3.08 Expiration of Restrictions. (a) Physical Notes. Any Physical Note
(or any security issued in exchange or substitution therefor) that does not constitute a Restricted
Note may be exchanged for a new Note or Notes of like tenor and aggregate Principal Amount that do
not bear the Restricted Notes Legend required by Section 3.07. To exercise such right of exchange,
the Holder of such Note must surrender such Note in accordance with the provisions of Section 3.11
and deliver any additional documentation reasonably required by the Company, the Trustee or the
Registrar in connection with such exchange.

     (b) Global Notes; Resale Restriction Termination Date.

     (i) If, on the Free Trade Date, or the next succeeding Business Day if the Free Trade
Date is not a Business Day, any Notes are represented by a Global Note that is a Restricted
Note (any such Global Note, a “Restricted Global Note”), as promptly as practicable, the
Company will automatically exchange every beneficial interest in each Restricted Global Note
for beneficial interests in Global Notes that are not subject to the restrictions set forth
in the Restricted Notes Legend and in Section 3.07 hereof.

     (ii) To effect such automatic exchange, the Company will (A) deliver to the Depositary
an instruction letter for the Depositary’s mandatory exchange process at least 15 days
immediately prior to the Free Trade Date and (B) deliver to each of the Trustee and the
Registrar a duly completed Free Transferability Certificate promptly after the Free Trade
Date, but not an Opinion of Counsel. The first date on which both the Trustee and the
Registrar have received the Free Transferability Certificate will be known as the “Resale
Restriction Termination Date.”

     (A) Immediately upon receipt of the Free Transferability Certificate by each of
the Trustee and the Registrar the Restricted Notes Legend will be deemed removed
from each of the Global Notes specified in such Free Transferability Certificate and
the restricted CUSIP number will be deemed removed from each of such Global Notes
and deemed replaced with an unrestricted CUSIP number.

     (B) Promptly after the Resale Restriction Termination Date, the Company (or the
Trustee upon instruction by the Company) will provide Bloomberg LLP with a copy of
the Free Transferability Certificate and will use reasonable efforts to cause
Bloomberg LLP to adjust its screen page for the Notes

31

 

to indicate that the Notes are no longer Restricted Notes and are now
identified by an unrestricted CUSIP number.

     (iii) Prior to the Company’s delivery of the Free Transferability Certificate and
afterwards, the Company and the Trustee will comply with the Applicable Procedures and
otherwise use reasonable efforts to cause each Global Note to be identified by an
unrestricted CUSIP number in the facilities of the Depositary by the date the Free
Transferability Certificate is delivered to the Trustee and the Registrar or as promptly as
possible thereafter.

     (iv) Notwithstanding anything to the contrary in Section 3.08(b)(i), (ii) or (iii), the
Company will not be required to deliver the Free Transferability Certificate if it
reasonably believes that removal of the Restricted Notes Legend or the changes to the CUSIP
numbers for the Notes could result in or facilitate transfers of the Notes in violation of
applicable law.

     Section 3.09 Mutilated, Destroyed, Lost and Stolen Notes. If any mutilated Note is
surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new Note of like tenor and Principal Amount and bearing a number not
contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be
required by them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Note has been acquired by a protected
purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Note, a new Note of like tenor and Principal Amount and bearing a
number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Note has become or is about to become
due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

     Upon the issuance of any new Note under this Section 3.09, the Company may require payment by
the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith.

     Every new Note issued pursuant to this Section 3.09 in lieu of any destroyed, lost or stolen
Note shall constitute an original additional contractual obligation of the Company, whether or not
the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with any and all other
Notes duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost
or stolen Notes.

32

 

     Section 3.10 Persons Deemed Owners. Prior to due presentment of a Note for registration of
transfer, the Company, the Guarantors, the Trustee, the Registrar and any agent of the Company, the
Guarantors, the Trustee or the Registrar may treat the Person in whose name such Note is registered
as the owner of such Note for the purpose of receiving payment of the principal of such Note and
for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company,
the Guarantors, the Trustee, the Registrar nor any agent of the Company, the Guarantors, the
Trustee or the Registrar shall be affected by notice to the contrary.

     Section 3.11 Transfer and Exchange.

     (a) Provisions Applicable to All Transfers and Exchanges.

     (i) Subject to the restrictions set forth in this Section 3.11, Physical Notes and
beneficial interests in Global Notes may be transferred or exchanged from time to time as
desired, and each such transfer or exchange will be noted by the Registrar in the Register.

     (ii) All Notes issued upon any registration of transfer or exchange in accordance with
this Indenture will be the valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture as the Notes surrendered upon such
registration of transfer or exchange.

     (iii) No service charge will be imposed on any Holder of a Physical Note or any owner
of a beneficial interest in a Global Note for any exchange or registration of transfer, but
each of the Company, the Trustee or the Registrar may require such Holder or owner of a
beneficial interest to pay a sum sufficient to cover any transfer tax, assessment or other
governmental charge imposed in connection with such registration of transfer or exchange.

     (iv) Unless the Company specifies otherwise, none of the Company, the Trustee, the
Registrar or any co-Registrar will be required to exchange or register a transfer of any
Note (i) that has been surrendered for conversion or (ii) as to which a Fundamental Change
Purchase Notice has been delivered and not withdrawn, in each case, except to the extent any
portion of such Note is not subject to the foregoing.

     (v) The Trustee will have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under
applicable law with respect to any transfer of any interest in any Note (including any
transfers between or among Depositary participants or beneficial owners of interests in any
Global Note) other than to require delivery of such certificates and other documentation or
evidence as are expressly required by, and to do so if and when expressly required by the
terms of, this Indenture, and to examine the same to determine substantial compliance as to
form with the express requirements hereof.

     (b) In General; Transfer and Exchange of Beneficial Interests in Global Notes. So
long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise

33

 

     (i) all Notes will be represented by one or more Global Notes;

     (ii) every transfer and exchange of a beneficial interest in a Global Note will be
effected through the Depositary in accordance with the Applicable Procedures and the
provisions of this Indenture (including the restrictions on transfer set forth in Section
3.07); and

     (iii) each Global Note may be transferred only as a whole and only (A) by the
Depositary to a nominee of the Depositary, (B) by a nominee of the Depositary to the
Depositary or to another nominee of the Depositary, or (C) by the Depositary or any such
nominee to a successor Depositary or a nominee of such successor Depositary.

     (c) Transfer and Exchange of Global Notes.

     (i) Notwithstanding any other provision of this Indenture, each Global Note will be
exchanged for Physical Notes if the Depositary delivers notice to the Company that:

     (A) the Depositary is unwilling or unable to continue to act as Depositary; or

     (B) the Depositary is no longer registered as a clearing agency under the
Exchange Act;

and, in each case, the Company promptly delivers a copy of such notice to the Trustee and
the Company fails to appoint a successor Depositary within 90 days after receiving notice
from the Depositary.

     In each such case, each Global Note will be deemed surrendered to the Trustee for
cancellation, and the Trustee will cause each Global Note to be cancelled in accordance with the
Applicable Procedures, and the Company, in accordance with Section 3.04, will promptly execute,
and, upon receipt of a Company Order, the Trustee will, in accordance with Section 3.04, will

an aggregate Principal Amount of Physical Notes equal to the aggregate Principal Amount of such
beneficial interest, registered in such names and in such authorized denominations as the
Depositary specifies, and bearing any legends that such Physical Notes are required to bear under
Section 3.07.

     (ii) In addition, if (x) the Company, in its discretion, subject to the Depositary’s
rules, determines that any Global Note will be exchangeable for Physical Notes or (y) an
Event of Default has occurred and is continuing, in each case, any owner of a beneficial
interest in a Global Note may exchange such beneficial interest for Physical Notes by
delivering a written request to the Registrar.

In such case, (A) the Registrar will deliver notice of such request to the Company and the
Trustee, which notice will identify the owner of the beneficial interest to be exchanged, the
aggregate principal amount of such beneficial interest and the CUSIP of the relevant Global Note;
(B) the Company will, in accordance with Section 3.04, promptly execute, and, upon

34

 

receipt of a Company Order, the Trustee, in accordance with Section 3.04, will promptly

Physical Notes registered in such owner’s name having an aggregate Principal Amount equal to the
aggregate Principal Amount of such beneficial interest and bearing any legends that such Physical
Notes are required to bear under Section 3.07, and (C) the Registrar, in accordance with the
Applicable Procedures, will cause the Principal Amount of such Global Note to be decreased by the
aggregate Principal Amount of the beneficial interest so exchanged. If all of the beneficial
interests in a Global Note are so exchanged, such Global Note will be deemed surrendered to the
Trustee for cancellation, and the Trustee will cause such Global Note to be cancelled in accordance
with the Applicable Procedures.

     (d) Transfer and Exchange of Physical Notes.

     (i) If Physical Notes are issued, a Holder may transfer a Physical Note by: (A)
surrendering such Physical Note for registration of transfer to the Registrar, together with
any endorsements or instruments of transfer required by any of the Company, the Trustee or

transfer complies with Section 3.07 and any applicable securities laws; and (C) satisfying
all other requirements for such transfer set forth in this Section 3.11 and Section 3.07.

Notes, of any authorized denominations, having like aggregate Principal Amount and bearing
any restrictive legends required by Section 3.07.

     (ii) If Physical Notes are issued, a Holder may exchange a Physical Note for other
Physical Notes of any authorized denominations and aggregate Principal Amount equal to the
aggregate Principal Amount of the Notes to be exchanged by surrendering such Notes, together
with any endorsements or instruments of transfer required by any of the Company, the Trustee
or the Registrar, at any office or agency maintained by the Company for such purposes
pursuant to Section 4.02. Whenever a Holder surrenders Notes for exchange, the Company, in
accordance with Section 3.04, will promptly execute and deliver to the Trustee, and the
Trustee, upon receipt of a Company Order, will, in accordance with Section 3.04, promptly
authenticate and deliver the Notes that such Holder is entitled to receive, bearing
registration numbers not contemporaneously outstanding and any restrictive legends that such
Physical Notes are to bear under Section 3.07.

     If Physical Notes are issued, a Holder may transfer or exchange a Physical Note for a
beneficial interest in a Global Note by (A) surrendering such Physical Note for registration of
transfer or exchange, together with any endorsements or instruments of transfer required by any of
the Company, the Trustee or the Registrar, at any office or agency maintained by the Company for
such purposes pursuant to Section 4.02; (B) if such Physical Note is a Restricted Note, delivering
any documentation the Company, the Trustee or the Registrar reasonably require to ensure that such
transfer complies with Section 3.07 and any applicable securities

35

 

laws; (C) satisfying all other requirements for such transfer set forth in this Section 3.11
and Section 3.07; and (D) providing written instructions to the Trustee to make, or to direct the
Registrar to make, an adjustment in its books and records with respect to the applicable Global
Note to reflect an increase in the aggregate Principal Amount of the Notes represented by such
Global Note, which instructions will contain information regarding the Depositary account to be
credited with such increase. Upon the satisfaction of conditions (A), (B), (C) and (D), the
Trustee will cancel such Physical Note and cause, or direct the Registrar to cause, in accordance
with the Applicable Procedures, the aggregate Principal Amount of Notes represented by such Global
Note to be increased by the aggregate Principal Amount of such Physical Note, and will credit or
cause to be credited the account of the Person specified in the instructions provided by the
exchanging Holder in an amount equal to the aggregate Principal Amount of such Physical Note. If
no Global Notes are then outstanding, the Company, in accordance with Section 3.04, will promptly
execute and deliver to the Trustee, and the Trustee, upon receipt of a Company Order, will, in
accordance with Section 3.04, authenticate, a new Global Note in the appropriate aggregate
Principal Amount.

     The Registrar shall retain, in accordance with its customary procedures, copies of all
letters, notices and other written communications received pursuant to this Section 3.11. The
Company shall have the right to inspect and make copies of all such letters, notices or other
written communications at any reasonable time upon the giving of reasonable written notice to the
Registrar.

     Section 3.12 Cancellation. The Company at any time may deliver to the Trustee for
cancellation any Notes previously authenticated and delivered hereunder that 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. The Trustee shall
cancel all Notes surrendered for registration of transfer, exchange, payment, purchase, repurchase,
conversion (pursuant to Article 7 hereof) or cancellation in accordance with its customary
practices. If the Company shall acquire any of the Notes, such acquisition shall not operate as a
redemption or satisfaction of the indebtedness represented by such Notes unless and until the same
are delivered to the Trustee for cancellation. The Notes so acquired, while held by or on behalf
of the Company or any of its Subsidiaries, shall not entitle the Holder thereof to convert the
Notes. The Company may not issue new Notes to replace Notes it has paid in full or delivered to
the Trustee for cancellation.

     Section 3.13 CUSIP Numbers. In issuing the Notes, the Company may use “CUSIP” numbers (if
then generally in use). The Company will promptly notify the Trustee of any change in the “CUSIP”
numbers.

additional interest will accrue thereon in respect of such delay.

     Section 4.02 Maintenance of Office or Agency. The Company shall maintain an office or

agency in the City and State of New York where the Notes may be surrendered or presented for
payment. The Company shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency not designated or appointed by the Trustee. If at
any time the Company shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office, and the Company hereby appoints the Trustee as
its agent to receive all such presentations, surrenders, notices and demands.

     The Company may also from time to time designate co-Registrars and one or more offices or
agencies where the Notes may be presented or surrendered for any or all such purposes and may from
time to time rescind such designations, provided that the Company shall at all times maintain an
office or agency in the City and State of New York where the Notes may be surrendered or presented
for payment.

     The Company will give prompt written notice of any such designation or rescission and of any
change in the location of any such other office or agency.

     Section 4.04 Provisions as to Paying Agent.

     (a) The Company may designate additional Paying Agents, rescind the designation of any Paying
Agent, or approve a change in the office through which any Paying Agent acts, provided that there

the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in
which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04:

37

 

     (i) that it will hold all sums held by it as such agent for the payment of the
principal of or interest on the Notes (whether such sums have been paid to it by the
Company or by any other obligor on the Notes) in trust for the benefit of the Holders of the
Notes;

     (ii) that it will give the Trustee notice of any failure by the Company (or by any
other obligor on the Notes) to make any payment of the principal of or interest on the
Notes when the same shall be due and payable; and

the Trustee, it will forthwith pay to the Trustee all sums so held in trust.

     The Company shall, on or before each due date of the principal of or interest on the Notes,
deposit with the Paying Agent a sum (in funds which are immediately available on the due date for
such payment) sufficient to pay such principal or interest, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided,
however, that if such deposit is made on the due date, such deposit shall be received by the Paying
Agent by 10:00 a.m. New York City time, on such date.

     (b) If the Company shall act as its own Paying Agent, it will, by 10:00 a.m. New York City
time on each due date of the principal of or interest on the Notes, set aside, segregate and hold
in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal or
interest so becoming due and will promptly notify the Trustee of any failure to take such action
and of any failure by the Company (or any other obligor under the Notes) to make any payment of the
principal of or interest on the Notes when the same shall become due and payable.

     (c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any
time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other
reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any Paying
Agent hereunder as required by this Section 4.04, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Company or any Paying Agent to the Trustee,
the Company or such Paying Agent shall be released from all further liability with respect to such
sums.

     (d) Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums
in trust as provided in this Section 4.04 is subject to Sections 13.03 and 13.04.

     The Trustee shall not be responsible for the actions of any other Paying Agents (including the
Company if acting as its own Paying Agent) and shall have no control of any funds held by such
other Paying Agents.

     Section 4.05 Existence. Subject to Article 10, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence and rights (charter
and statutory); provided, however, that the Company shall not be required to preserve any such
right if the Company shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company.

     Section 4.06 [Reserved]

     Section 4.07 [Reserved]

     Section 4.08 Rule 144A Information Requirement. The Company covenants and agrees that it
shall, during any period in which it is not subject to Section 13 or 15(d) under the Exchange Act,
so long as any of the Notes or shares of Common Stock delivered upon conversion of the Notes will,
at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the
Securities Act, promptly provide to the Trustee and will, upon written request, provide to any
Holder or beneficial owner of such Notes or such shares of Common Stock and any prospective
purchaser of such Notes or such shares of Common Stock, the information required pursuant to Rule
144A(d)(4) under the Securities Act to facilitate the resale of such Notes or such shares of Common
Stock pursuant to Rule 144A under the Securities Act, and it will take such further action as any
Holder or beneficial owner of such Notes or such shares of Common Stock may reasonably request from
time to time to enable such Holder or beneficial owner to sell such Notes or such shares of Common
Stock in accordance with Rule 144A, as such rule may be amended from time to time.

     Section 4.09 Resale of Certain Notes. The Company shall not, and shall not permit any of
its Subsidiaries to, resell any Notes that have been reacquired by the Company or any such
Subsidiary. The Trustee shall have no responsibility in respect of the Company’s performance of

the Exchange Act shall be filed within the time periods specified in the rules and regulations of
the Commission (including any grace period provided by Rule 12b-25 under the Exchange Act), and
must be filed by the Company with the Trustee within 15 days after the same are filed with the
Commission; provided that in each case the delivery of materials to the Trustee by electronic means
or filing of documents pursuant to the Commission’s “EDGAR” system (or any successor electronic
filing system) shall be deemed to constitute “filing” with the Trustee for purposes of this Section
4.10. Delivery of such reports, information and documents to the Trustee is for informational
purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to
rely exclusively on Officers’ Certificates). The Company shall at all times comply with Trust
Indenture Act § 314(a).

     Section 4.11 Book-Entry System. If the Notes cease to trade in the Depositary’s book-entry
settlement system, the Company covenants and agrees that it shall use reasonable efforts to make
such other book entry arrangements that it determines are reasonable for the Notes.

     Section 4.12 Additional Interest. If at any time Additional Interest becomes payable by
the Company pursuant to Section 9.03, the Company shall promptly deliver to the Trustee a
certificate to that effect and stating (i) the amount of such Additional Interest that is payable
and (ii) the date on which such Additional Interest is payable. Unless and until a Trust Officer
of the Trustee receives such a certificate, the Trustee may assume without inquiry that no
Additional

39

 

Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled
to such Additional Interest, the Company shall deliver to the Trustee a certificate setting forth
the particulars of such payment.

     Section 4.13 [RESERVED].

     Section 4.14 Stay; Extension and Usury Laws. Each of the Company and the Guarantors
covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon,
plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law or other law which would prohibit or forgive the Company or the Guarantors 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 which may affect the covenants or the
performance of this Indenture and each of the Company and the Guarantors (to the extent it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants
that it will not, by resort to any such law, 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.

     Section 4.15 Compliance Certificate. The Company shall deliver to the Trustee, within one
hundred twenty (120) days after the end of each fiscal year of the Company (commencing with the
fiscal year ending December 31, 2011), an Officers’ Certificate, stating whether or not to the
knowledge of the signer thereof the Company is in default in the performance and observance of any
of the terms, provisions and conditions of this Indenture (without regard to any period of grace or
requirement of notice provided hereunder) and, if the Company shall be in default, specifying all
such defaults and the nature and the status thereof of which the signer may have knowledge.

     The Company shall deliver to the Trustee, within 30 days after the Company becomes aware of
the occurrence of any Event of Default or Default, a written notice setting forth the details of
such Event of Default or Default, its status and the action which the Company proposes to take with
respect thereto.

     Any notice required to be given under this Section 4.15 shall be delivered to a Trust Officer
of the Trustee at its Corporate Trust Office.

     Section 4.16 Additional Subsidiary Guarantees. If, after the date of this Indenture, any
Material Domestic Subsidiary of the Company that is not already a Guarantor guarantees any other
Indebtedness of the Company or any Guarantor in excess of the De Minimis Guaranteed Amount, then
that Subsidiary shall become a Guarantor by executing a supplemental indenture substantially in the
form of Annex A hereto and delivering it to the Trustee within 30 days of the date on which
it guaranteed such Indebtedness, together with an Officers’ Certificate and Opinion of Counsel as
required by Sections 1.02 and 14.03.

     Each Subsidiary Guarantee shall also be released in accordance with Article 15.

CONVERSION

     Section 7.01 Right to Convert.

     (a) Subject to and upon compliance with the provisions of this Indenture, each Holder shall
have the right, at such Holder’s option, at any time prior to the Close of Business on the Business
Day immediately preceding the Maturity Date, to convert the Principal Amount of any such Notes, or
any portion of such Principal Amount, into shares of Common Stock, provided that any portion of
such Principal Amount that a Holder elects to convert is equal to $1,000 or an integral multiple of
$1,000 in excess thereof.

     (b) Notwithstanding the foregoing, if a Holder has already delivered a Fundamental Change
Purchase Notice with respect to a Note under Section 8.01, such Holder may convert such Note only
if such Holder first withdraws the related Fundamental Change Purchase Notice pursuant to Section
8.03. If a Holder has surrendered such Holder’s Note for required purchase in connection with a
Fundamental Change, such Holder’s right to withdraw the related Fundamental Change Purchase Note
and convert each Note that is subject thereto will terminate at the Close of Business on (i) the
Business Day immediately preceding the relevant Fundamental Change Purchase Date or (ii) in the
case of a Default by the Company in the payment of the Fundamental Change Purchase Price with
respect to such Note, the Business Day immediately preceding the day on which such Default is no
longer continuing.

     (c) Provisions of this Indenture that apply to conversion of all of a Note also apply to
conversion of a portion of a Note.

     (d) A Holder of Notes is not entitled to any rights of a holder of shares of Common Stock
until such Holder has converted its Notes, and only to extent such Notes are deemed to have been
converted into shares of Common Stock pursuant to this Article 7.

     Section 7.02 Conversion Procedure.

     (a) Each Note shall be convertible at the office of the Conversion Agent.

     (b) In order to exercise the conversion right with respect to any interest in Global Notes,
the Holder must complete the appropriate instruction form for conversion pursuant to the
Depositary’s book-entry conversion program, furnish appropriate endorsements and transfer documents
if required by the Company or the Trustee or Conversion Agent, and pay the funds, if any, required
by Section 7.03(c) and any transfer taxes or duties if required pursuant to Section 7.08. However,
no service charge will be imposed by the Company, the Trustee or the Registrar for any registration
of transfer or exchange of Notes except in compliance with the below provisions governing exercise
of conversion rights. In order to exercise the conversion

41

 

right with respect to any Physical Notes, the Holder of any such Notes to be converted, in whole or in
part, shall:

     (i) complete and manually sign the conversion notice provided on the back of the Note
(the “Conversion Notice”) or facsimile of the Conversion Notice and deliver such notice to a
Conversion Agent, which action shall be irrevocable;

     (ii) surrender the Note to a Conversion Agent;

     (iii) if required, furnish appropriate endorsements and transfer documents,

     (iv) if required pursuant to Section 7.08, pay any transfer taxes or duties; and

     (v) if required, pay funds equal to interest (including Additional Interest, if any)
payable on the next Interest Payment Date to which the Holder is not entitled as required by
Section 7.03(c).

     The date on which the Holder satisfies all of the applicable requirements set forth above is
the “Conversion Date.”

     (c) On the third Business Day immediately following the Conversion Date, the Company shall
issue and shall deliver to the converting Holder at the office of the Conversion Agent, a
certificate or certificates for the number of full shares of Common Stock issuable in respect of
such conversion in accordance with the provisions of this Article 7. In case any Notes of a
denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of the Notes so surrendered,
without charge to such Holder, new Notes in authorized denominations in an aggregate Principal
Amount equal to the unconverted portion of the surrendered Notes.

     Each conversion shall be deemed to have been effected as to any such Notes (or portion
thereof) on the date on which the requirements set forth above in Section 7.01(b) have been
satisfied as to such Notes (or portion thereof) and the Person in whose name any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to
have become, as of the Close of Business on the relevant Conversion Date that such Holder converted
the Notes, the holder of record of the shares of Common Stock represented thereby.

     (d) Upon the conversion of an interest in a Global Note, the Trustee (or other Conversion
Agent appointed by the Company) shall make a notation on such Global Note as to the reduction in
the Principal Amount represented thereby. The Company shall notify the Trustee in writing of any
conversions of Notes effected through any Conversion Agent other than the Trustee.

     (e) Each share certificate representing Common Stock issued upon conversion of the Notes that
are Restricted Notes shall bear the Restricted Stock Legend as set forth in Section 3.07 and
Exhibit A.

     Section 7.03 Settlement upon Conversion.

42

 

     (a) With respect to any conversion of Notes, if any, the Company shall, subject to the
provisions of this Article 7, deliver to converting Holders, in respect of each $1,000 Principal
Amount of Notes being converted, a number of shares of Common Stock equal to the Applicable
Conversion Rate, on the third Business Day immediately following the relevant Conversion Date,
together with cash in lieu of any fractional shares of Common Stock pursuant to Section 7.03(d).

     (b) Upon conversion, Holders shall not receive any separate cash payment for accrued and
unpaid interest unless such conversion occurs between a Regular Record Date and the Interest
Payment Date to which it relates and the converting Holder was the Holder on the relevant Regular
Record Date.

     (c) If Notes are converted after the Close of Business on a Regular Record Date for the
payment of interest, Holders of such Notes at the Close of Business on such Regular Record Date
will receive the interest payable on such Notes on the corresponding Interest Payment Date
notwithstanding the conversion. Notes surrendered for conversion during the period from the Close
of Business on any Regular Record Date to the Open of Business on the immediately following
Interest Payment Date, must be accompanied by funds equal to the amount of interest payable on the
Notes so converted; provided that no such payment need be made (i) for conversions following the
Regular Record Date immediately preceding the Maturity Date; (ii) if the Company has specified a
Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the first
Business Day immediately following the corresponding Interest Payment Date; or (iii) to the extent
of any overdue interest, if any overdue interest exists at the time of conversion with respect to
such Note.

     (d) The Company shall not issue fractional shares upon conversion of Notes. If multiple Notes
shall be surrendered for conversion at one time by the same Holder, the number of full shares which
shall be issuable upon conversion (and the number of fractional shares, if any, for which cash
shall be delivered) shall be computed on the basis of the aggregate Principal Amount of the Notes
(or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional
share would be issuable upon the conversion of any Notes, the Company shall make payment an amount
in cash for the current market value of the fractional shares. The current market value of a
fractional share shall be determined (calculated to the nearest 1/1000th of a share) by multiplying
the Last Reported Sale Price of the Common Stock on the relevant Conversion Date by such fractional
share and rounding the product to the nearest whole cent.

     (e) By delivery to the Holder of the full number of shares of Common Stock, together with any
cash payment for fractional shares, issuable upon conversion, the Company will be deemed to satisfy
in full its obligation to pay the Principal Amount of the Notes and all accrued and unpaid interest
to, but excluding, the Conversion Date. Upon conversion of the Notes, all accrued and unpaid
interest to, but excluding, the Conversion Date will be deemed to be paid in full rather than
canceled, extinguished or forfeited, subject to Section 7.03(c) above.

     Section 7.04 Adjustment of Conversion Rate. The Applicable Conversion Rate shall be
adjusted from time to time by the Company if any of the following events occurs as described below,
except that the Company will not make any adjustment to the Conversion Rate if Holders

43

 

of Notes participate (other than in the case of a share split or share combination), at the same
time and on the same terms as holders of shares of Common Stock, solely as a result of holding the
Notes, in any of the transactions described in this Section 7.04, without having to convert their
Notes, as if such Holders held a number of shares of Common Stock equal to the Applicable
Conversion Rate in effect immediately prior to the adjustment thereof in respect of such
transaction, multiplied by the Principal Amount of Notes held by such Holders, divided by $1,000.

     (a) If the Company issues shares of Common Stock as a dividend or distribution on the Common
Stock, or if the Company effects a share split or share combination of its Common Stock, the
Applicable Conversion Rate will be adjusted based on the following formula:

where,

	 	 	 

	     CR0 =

	 	the Applicable Conversion Rate in effect immediately prior to the Close of
Business on the Record Date for such dividend or distribution, or immediately prior to
the Open of Business on the effective date of such share split or share combination, as
applicable;
	 
	 	 
	     CR1 =

	 	the Applicable Conversion Rate in effect immediately after the Close of
Business on such Record Date or immediately after the Open of Business on such
effective date, as applicable;
	 
	 	 
	     OS0 =

	 	the number of shares of Common Stock outstanding immediately prior to the
Close of Business on such Record Date or immediately prior to the Open of Business on
such effective date, as applicable; and
	 
	 	 
	     OS1 =

	 	the number of shares of Common Stock outstanding immediately after giving
effect to such dividend, distribution, share split or share combination.

     Any adjustment made pursuant to this Section 7.04(a) shall become effective immediately after
the Close of Business on the Record Date for such dividend or distribution, or immediately after
the Open of Business on the effective date for such share split or share combination, as
applicable. If any dividend or distribution of the type described in this Section 7.04(a) is
declared but not so paid or made, or any such share split or combination is announced but the
outstanding shares of Common Stock are not split or combined, as the case may be, the Applicable
Conversion Rate shall be immediately readjusted, effective as of the date the Company’s Board of
Directors determines not to pay such dividend or distribution, or not to split or combine the
outstanding shares of Common Stock, as the case may be, to the Conversion Rate that would then be
in effect if such dividend, distribution, share split or share combination had

44

 

not been declared or announced. For the avoidance of doubt, if the application of the
foregoing formula would result in a decrease in the Applicable Conversion Rate, no adjustment to
the Applicable Conversion Rate will be made (other than (i) as a result of a reverse share split or
share combination or (ii) with respect to the Company’s right to readjust the Applicable Conversion
Rate as described in the immediately preceding sentence).

     (b) If the Company distributes to all or substantially all holders of shares of Common Stock
any rights, options or warrants entitling them for a period of not more than 60 calendar days after
the date of such distribution to subscribe for or purchase shares of Common Stock, at a price per
share less than the average of the Last Reported Sale Prices of the Common Stock over the 10
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
date of such distribution, the Applicable Conversion Rate will be increased based on the following
formula:

where,

	 	 	 

	     CR0 =

	 	the Applicable Conversion Rate in effect immediately prior to the Close of
Business on the Record Date for such distribution;
	 
	 	 
	     CR1 =

	 	the Applicable Conversion Rate in effect immediately after the Close of
Business on such Record Date;
	 
	 	 
	     OS0 =

	 	the number of shares of Common Stock outstanding immediately prior to the
Close of Business on such Record Date;
	 
	 	 
	     X =

	 	the total number of shares of Common Stock issuable pursuant to such rights,
options or warrants; and
	 
	 	 
	     Y =

	 	the number of shares of Common Stock equal to the aggregate price payable to
exercise such rights, options or warrants divided by the average of the Last Reported
Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on,
and including, the Trading Day immediately preceding the date of announcement of the
distribution of such rights, options or warrants.

     The foregoing increase in the Applicable Conversion Rate shall be successively made whenever
any such rights, options or warrants are distributed and shall become effective immediately after
the Close of Business on the Record Date for such distribution. If such rights, options or
warrants are not so distributed, the Applicable Conversion Rate will be immediately decreased to
the Conversion Rate that would then be in effect if such Record Date for such

45

 

distribution had not been fixed. In addition, to the extent that shares of Common Stock are
not delivered after the expiration of such rights, options or warrants, the Applicable Conversion
Rate shall be immediately decreased to the Conversion Rate that would then be in effect had the
increase made for the distribution of such rights, options or warrants been made on the basis of
delivery of only the number of shares of Common Stock actually delivered. For the avoidance of
doubt, if the application of the foregoing formula would result in a decrease in the Applicable
Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the
Company’s right to readjust the Applicable Conversion Rate as described in the two immediately
preceding sentences).

     In determining whether any rights, options or warrants entitle the holders of shares of Common
Stock to subscribe for or purchase or exercise conversion rights for, shares of Common Stock at a
purchase price less than such average of the Last Reported Sale Prices of Common Stock over the 10
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
date of announcement of such distribution, and in determining the aggregate exercise or purchase
price payable for such shares of Common Stock, there shall be taken into account any consideration
received by the Company for such rights, options or warrants and any amount payable upon exercise
or conversion thereof, the value of such consideration, if other than cash, to be determined by the
Company’s Board of Directors.

     (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness,
other assets or property of the Company or rights, options or warrants to acquire the Company’s
Capital Stock or other securities (the “Distributed Property”), to all or substantially all holders
of shares of Common Stock, excluding:

     (i) dividends or distributions of Common Stock or rights, options or warrants as to
which an adjustment was effected pursuant to Section 7.04(a) or Section 7.04(b), as the case
may be;

     (ii) dividends or distributions paid exclusively in cash as to which an adjustment was
effected pursuant to Section 7.04(d); and

     (iii) Spin-Offs to which the provisions set forth below in this Section 7.04(c) apply;

then the Applicable Conversion Rate will be increased based on the following formula:

where,

46

 

	 	 	 

	     CR0 =

	 	the Applicable Conversion Rate in effect immediately prior to the Close of
Business on the Record Date for such distribution;
	 
	 	 
	     CR1 =

	 	the Applicable Conversion Rate in effect immediately after the Close of
Business on such Record Date;
	 
	 	 
	     SP0 =

	 	the average of the Last Reported Sale Prices of the Common Stock over the
10 consecutive Trading Day period ending on, and including, the Trading Day immediately
preceding the Ex-Dividend Date for such distribution; and
	 
	 	 
	     FMV =

	 	the fair market value (as determined by the Company’s Board of Directors) of
the Distributed Property distributed with respect to each outstanding share of Common
Stock on the Ex-Dividend Date for such distribution;

provided that if “FMV” as set forth above is equal to or greater than “SP0” as set forth
above, in lieu of the foregoing increase, adequate provision will be made so that each Holder of a
Note shall receive on the date on which the Distributed Property is distributed to holders of the
Common Stock, for each $1,000 Principal Amount of the Notes, the amount and kind of Distributed
Property that such Holder would have received had such Holder owned a number of shares of Common
Stock equal to the Applicable Conversion Rate on the Record Date for such distribution; provided
further that if the Company’s Board of Directors determines “FMV” for purposes of the foregoing
increase by reference to the actual or when-issued trading market for any securities, it must in
doing so consider the prices in such market over the same period used in computing the average of
the Last Reported Sale Prices of the Common Stock for purposes of determining “SP0” as
set forth above.

     An increase in the Applicable Conversion Rate made pursuant to the immediately preceding
paragraph shall become effective immediately after the Close of Business on the Record Date for
such distribution. If such distribution is declared but not so paid or made, the Applicable
Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such
distribution had not been declared. For the avoidance of doubt, if the application of the foregoing
formula would result in a decrease in the Applicable Conversion Rate, no adjustment to the
Conversion Rate will be made (other than with respect to the Company’s right to readjust the
Applicable Conversion Rate as described in the immediately preceding sentence).

     With respect to an adjustment pursuant to this Section 7.04(c) where there has been a payment
of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or
series, or similar equity interest, of or relating to a Subsidiary, or other business unit or
affiliate, of the Company, where such Capital Stock or similar equity interest is listed or quoted
(or will be listed or quoted upon consummation of the Spin-Off) on The New York Stock Exchange, The
NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors) (a
“Spin-Off”), the Applicable Conversion Rate will be increased based on the following formula:

47

 

where,

	 	 	 

	     CR0 =

	 	the Applicable Conversion Rate in effect immediately prior to the end of
the Valuation Period;
	 
	 	 
	     CR1 =

	 	the Applicable Conversion Rate in effect immediately after the end of the
Valuation Period;
	 
	 	 
	     FMV0 =

	 	the average of the Last Reported Sale Prices of the Capital Stock or
similar equity interest distributed to holders of shares of Common Stock applicable to
one share of Common Stock (determined for purposes of the definition of “Last Reported
Sale Price” as if such Capital Stock or similar equity interest were Common Stock) over
the first ten consecutive Trading Day period after, and including, the effective date
of the Spin-Off (the “Valuation Period”); and
	 
	 	 
	     MP0 =

	 	the average of the Last Reported Sale Prices of the Common Stock over the
Valuation Period.

     The increase in the Applicable Conversion Rate under the immediately preceding paragraph will
be determined as of the Close of Business on the last Trading Day of the Valuation Period but will
be given effect immediately after the Close of Business on the Record Date of the Spin-Off;
provided that in respect of any conversion during the Valuation Period, references with respect to
10 consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as
have elapsed from, and including, the effective date of such Spin-Off to, and including, the
Conversion Date in determining the Applicable Conversion Rate. If any dividend or distribution
that constitutes a Spin-Off is declared but not so paid or made, the Applicable Conversion Rate
shall be immediately decreased, effective as of the date the Company’s Board of Directors
determines not to pay such dividend or distribution, to the Conversion Rate that would then be in
effect if such dividend or distribution had not been declared. For the avoidance of doubt, if the
application of the foregoing formula would result in a decrease in the Applicable Conversion Rate,
no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right
to readjust the Applicable Conversion Rate as described in the immediately preceding sentence).

     For purposes of this Section 7.04(c) (and subject in all respect to Section 7.12), rights,
options or warrants distributed by the Company to all holders of the Common Stock entitling them to
subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either
initially or under certain circumstances), which rights, options or warrants, until the occurrence
of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common
Stock, shall be deemed not to have been distributed for purposes of this Section 7.04(c) (and no
adjustment to the Applicable Conversion Rate under this Section 7.04(c) will be required) until the
occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be
deemed to have been distributed and an appropriate adjustment (if any is required) to the
Applicable Conversion Rate shall be made under this Section 7.04. If any such right, option or
warrant, including any such existing rights, options or warrants distributed

48

 

prior to the date of this Indenture, is subject to events, upon the occurrence of which such
rights, options or warrants become exercisable to purchase different securities, evidences of
indebtedness or other assets or property, then the date of the occurrence of any and each such
event shall be deemed to be the date of distribution and Record Date with respect to new rights,
options or warrants with such rights (in which case the existing rights, options or warrants shall
be deemed to terminate and expire on such date without exercise by any of the holders thereof). In
addition, in the event of any distribution (or deemed distribution) of rights, options or warrants,
or any Trigger Event or other event (of the type described in the immediately preceding sentence)
with respect thereto that was counted for purposes of calculating a distribution amount for which
an adjustment to the Applicable Conversion Rate under this Section 7.04(c) was made, (1) in the
case of any such rights, options or warrants that shall all have been redeemed or purchased without
exercise by any holders thereof, upon such final redemption or purchase (x) the Applicable
Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and
(y) the Applicable Conversion Rate shall then again be readjusted to give effect to such
distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash
distribution, equal to the per share of Common Stock redemption or purchase price received by a
holder or holders of shares of Common Stock with respect to such rights, options or warrants
(assuming such holder had retained such rights, options or warrants), made to all holders of shares
of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights,
options or warrants that shall have expired or been terminated without exercise by any holders
thereof, the Applicable Conversion Rate shall be readjusted as if such rights, options and warrants
had not been issued.

     For purposes of Section 7.04(a), Section 7.04(b) and this Section 7.04(c), any dividend or
distribution to which this Section 7.04(c) is applicable that also includes one or both of:

     (A) a dividend or distribution of shares of Common Stock to which Section
7.04(a) is applicable (the “Clause A Distribution”); or

     (B) a dividend or distribution of rights, options or warrants to which Section
7.04(b) is applicable (the “Clause B Distribution”),

then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B
Distribution, shall be deemed to be a dividend or distribution to which this Section 7.04(c) is
applicable (the “Clause C Distribution”) and any adjustment to the Applicable Conversion Rate
required by this Section 7.04(c) with respect to such Clause C Distribution shall then be made, and
(2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the
Clause C Distribution and any adjustment to the Applicable Conversion Rate required by Section
7.04(a) and Section 7.04(b) with respect thereto shall then be made, except that, if determined by
the Company (I) the “Record Date” for the Clause A Distribution and the Clause B Distribution shall
be deemed to be the Record Date for the Clause C Distribution and (II) any shares of Common Stock
included in the Clause A Distribution or Clause B Distribution shall be deemed not to be
“outstanding immediately prior to the Close of Business on such Record Date or immediately prior to
the Open of Business on such effective date, as applicable” within the meaning of Section 7.04(a)
or “outstanding immediately prior to the Close of Business on such Record Date” within the meaning
of Section 7.04(b).

49

 

     (d) If any cash dividend or distribution is paid or made to all or substantially all holders
of shares of Common Stock, the Applicable Conversion Rate shall be increased based on the following
formula:

where,

	 	 	 	 	 

	 

	 	CR0 =
	 	the Applicable Conversion Rate in effect immediately prior to the Close of
Business on the Record Date for such dividend or distribution;
	 
	 	 	 	 
	 

	 	CR1 =
	 	the Applicable Conversion Rate in effect immediately after the Close of
Business on the Record Date for such dividend or distribution;
	 
	 	 	 	 
	 

	 	SP0 =
	 	the average of the Last Reported Sale Prices of the Common Stock over the
10 consecutive Trading Day period ending on, and including, the Trading Day immediately
preceding the Ex-Dividend Date for such dividend or distribution; and
	 
	 	 	 	 
	 

	 	C =
	 	the amount in cash per share the Company distributes to holders of shares of
Common Stock.

     The increase in the Conversion Rate under this Section 7.04(d) will become effective
immediately after the Close of Business on the Record Date for such dividend or distribution. If
such dividend or distribution is declared but not so paid or made, the Applicable Conversion Rate
shall be immediately decreased to the Conversion Rate that would then be in effect if such dividend
or distribution had not been declared. For the avoidance of doubt, if the application of the
foregoing formula would result in a decrease in the Applicable Conversion Rate, no adjustment to
the Conversion Rate will be made (other than with respect to the Company’s right to readjust the
Applicable Conversion Rate as described in the immediately preceding sentence).

     Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, for each $1,000 Principal Amount of Notes, at the same time and upon the same terms as
holders of shares of Common Stock, the amount of cash that such Holder would have received if such
Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the
Record Date for such dividend or distribution.

     (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or
exchange offer for shares of Common Stock (excluding odd lots of shares of Common Stock), to the
extent that the cash and fair market value of any other consideration included in the payment per
share of Common Stock exceeds the average of the Last Reported Sale Prices of the

50

 

Common Stock over the 10 consecutive Trading Day period immediately following, and including, the Trading Day next
succeeding the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant
to such tender offer or exchange offer, the Applicable Conversion Rate will be increased based on
the following formula:

where

	 	 	 	 	 

	 

	 	CR0 =
	 	the Applicable Conversion Rate in effect immediately prior to the Close of
Business on the Trading Day next succeeding the Expiration Date;
	 
	 	 	 	 
	 

	 	CR1 =
	 	the Applicable Conversion Rate in effect immediately after the Close of
Business on the Trading Day next succeeding the Expiration Date;
	 
	 	 	 	 
	 

	 	AC =
	 	the aggregate fair market value of all cash and any other consideration (as
determined by the Company’s Board of Directors) paid or payable for shares of Common
Stock purchased in such tender offer or exchange offer;
	 
	 	 	 	 
	 

	 	OS0 =
	 	the number of shares of Common Stock outstanding immediately prior to the
Expiration Date (prior to giving effect to the purchase of all shares of Common Stock
accepted for purchase or exchange in such tender offer or exchange offer);
	 
	 	 	 	 
	 

	 	OS1 =
	 	the number of shares of Common Stock outstanding immediately after the
Expiration Date (after giving effect to the purchase of all shares of Common Stock
accepted for purchase or exchange in such tender offer or exchange offer); and
	 
	 	 	 	 
	 

	 	SP1 =
	 	the average of the Last Reported Sale Prices of Common Stock over the 10
consecutive Trading Day period immediately following, and including, the Trading Day
next succeeding the Expiration Date.

     The increase in the Applicable Conversion Rate under this Section 7.04(e) shall occur at the
Close of Business on the 10th Trading Day immediately following the Trading Day next succeeding the
Expiration Date but will be given effect immediately after the Close of Business on the Expiration
Date; provided that in respect of any conversion within the 10 consecutive Trading Day period
immediately following, and including, the Expiration Date, references to 10 consecutive Trading
Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and
including, the Expiration Date to, and including, the Conversion Date in determining the Applicable
Conversion Rate.

51

 

     If the Company is obligated to purchase shares of Common Stock pursuant to any such tender
offer or exchange offer, but the Company is ultimately prevented by applicable law from effecting
all or any portion of such purchases or all such purchases are rescinded, the Applicable Conversion
Rate shall immediately be readjusted to the Conversion Rate that would then be in effect if such
tender offer or exchange offer had not been made or had been made only in respect of the purchases
that had been effected. For the avoidance of doubt, if the application of the foregoing formula
would result in a decrease in the Applicable Conversion Rate, no adjustment to the Applicable
Conversion Rate will be made (other than with respect to the Company’s right to readjust the
Conversion Rate as described in the immediately preceding sentence).

     (f) [RESERVED]

     (g) In addition to those Conversion Rate adjustments required by Sections 7.04(a), 7.04(b),
7.04(c), 7.04(d) and 7.04(e), and to the extent permitted by applicable law and subject to the
applicable rules of The New York Stock Exchange and, if applicable, any other securities exchange
on which the Company’s securities are then listed, the Company from time to time (i) may increase
the Conversion Rate by any amount for a period of at least 20 Business Days if the Company’s Board
of Directors determines that such increase would be in the Company’s best interest and (ii) may
also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to
holders of shares of Common Stock or rights to purchase shares of Common Stock in connection with
any dividend or distribution of shares of Common Stock (or rights to acquire shares of Common
Stock) or similar event. Whenever the Conversion Rate is increased pursuant to this Section
7.04(g), the Company shall mail to Holders of record of the Notes a notice of the increase (in lieu
of any notice otherwise required under Section 7.04(j) below) at least 5 days prior to the date the
increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate
and the period during which it will be in effect.

     (h) The Applicable Conversion Rate will not be adjusted, among other things:

     (i) upon the issuance of any shares of Common Stock pursuant to any future plan
providing for the reinvestment of dividends or interest payable on the Company’s securities
and the investment of additional optional amounts in shares of Common Stock under any plan;

     (ii) upon the issuance of any shares of Common Stock or options or rights to purchase
those shares pursuant to any present or future employee or director benefit plan or program
of the Company, or assumed by the Company, or any of the Company’s Subsidiaries;

     (iii) upon the issuance of any shares of Common Stock pursuant to the 11.5% Convertible
Bonds or any other option, warrant, right or exercisable, exchangeable or convertible
security not described in clause (ii) above and outstanding as of the date the Notes were
first issued, except as set forth in Section 7.12;

     (iv) for a change in the par value of the Common Stock; or

     (v) for accrued and unpaid interest, and Additional Interest, if any.

52

 

     (i) Adjustments to the Applicable Conversion Rate under this Article 7 shall be calculated to
the nearest cent or to the nearest one-ten thousandth (1/10,000th) of a share of Common Stock. No
adjustment shall be made to the Conversion Rate unless such adjustment would require a change of at
least 1% in the Applicable Conversion Rate. Any adjustment that would otherwise be required to be
made shall be carried forward and taken into account in any future adjustment. Notwithstanding the
foregoing, upon any conversion of the Notes (solely with respect to the Notes to be converted), the
Company shall give effect to all adjustments that Company otherwise has deferred pursuant to the
immediately preceding sentence, and those adjustments will no longer be carried forward and taken
into account in any future adjustment.

     (j) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee and any Conversion Agent an Officers’ Certificate setting forth
the Conversion Rate after such adjustment and setting forth a brief statement of the facts
requiring such adjustment. Unless and until a Trust Officer of the Trustee shall have received
such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of
the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has
knowledge is still in effect. Promptly after delivery of such certificate, the Company shall
prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion
Rate and the date on which each adjustment became effective and shall mail such notice of such
adjustment of the Conversion Rate to each Holder at such Holder’s latest address appearing in the
Register, within 20 days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of any such adjustment.

     (k) In any case in which this Section 7.04 provides that an adjustment shall become effective
immediately after a Record Date for an event, the Company may defer until the occurrence of such
event (i) issuing to the Holder of any Notes converted after such Record Date and before the
occurrence of such event the additional shares of Common Stock issuable upon such conversion by
reason of the adjustment required by such event over and above the Common Stock issuable upon such
conversion before giving effect to such adjustment and (ii) paying to such Holder any amount in
cash in lieu of any fraction pursuant to Section 7.03.

     (l) For purposes of this Section 7.04, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company, so long as the Company
does not pay any dividend or make any distribution on shares of Common Stock held in the treasury
of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu
of fractions of shares of Common Stock.

     Section 7.05 Effect of Reclassification, Consolidation, Merger or Sale. In the case of (i)
any recapitalization, reclassification or change of the Common Stock (other than changes resulting
from a subdivision or combination), (ii) any consolidation, merger or combination involving the
Company, (iii) any sale, lease or other transfer to a third party of all or substantially all of
the consolidated assets of the Company and its Subsidiaries, or (iv) any statutory share exchange,
in each case, as a result of which the Common Stock would be converted into, or exchanged for,
stock, other securities, other property or assets (including cash or any combination thereof) (any
such event, a “Merger Event”), then, at the effective time of the Merger Event, the Company shall
execute with the Trustee a supplemental indenture permitted under Section 14.01 providing for the
right to convert each $1,000 Principal Amount

53

 

of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a
holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such
Merger Event would have owned or been entitled to receive (the “Reference Property”) upon such
Merger Event. If such Merger Event causes the Common Stock to be converted into the right to
receive more than a single type of consideration (determined based in part upon any form of
shareholder election), the Reference Property into which the Notes will be convertible will be
deemed to be the weighted average of the types and amounts of consideration received by the holders
of shares of Common Stock that affirmatively make such an election. The Company shall notify
Holders of the Notes of such weighted average as soon as practicable after such determination is
made. The Company shall not become a party to any Merger Event unless its terms are consistent
with the foregoing. For the avoidance of doubt, adjustments to the Conversion Rate pursuant to Section 7.04 do not apply to
distributions to the extent that the right to convert the Notes has been changed into the right to
convert into, or exchange for, Reference Property.

     The Company shall cause notice of the execution of such supplemental indenture to be mailed to
each Holder, at the address of such Holder as it appears on the Register, within 20 days after
execution thereof. Failure to deliver such notice shall not affect the legality or validity of
such supplemental indenture. The above provisions of this Section shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations, sales and
conveyances. If this Section 7.05 applies to any event or occurrence, Section 7.04 shall not
apply.

     Section 7.06 Adjustments of Prices. Whenever any provision of this Indenture requires a
calculation of the Last Reported Sale Prices over a span of multiple days (including with respect
to the Share Price for purposes of a Make-Whole Fundamental Change), the Company will make
appropriate adjustments determined by the Company or its agents to account for any adjustment to
the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion
Rate where the Ex-Dividend Date, Record Date, effective date or expiration date, as the case may
be, of the event occurs, at any time during the period during which such prices are to be
calculated. Such adjustments will be effective as of the Ex-Dividend Date, Record Date, effective
date or expiration date, as the case may be, of the event causing the adjustment to the Conversion
Rate.

     Section 7.07 Adjustment upon a Make-Whole Fundamental Change.

     (a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Notes in
connection with such Make-Whole Fundamental Change, the Company shall increase the Conversion Rate
for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the
“Additional Shares”) as described below. A conversion of Notes shall be deemed for these purposes
to be “in connection with” such Make-Whole Fundamental Change if the notice of conversion of the
Notes is received by the Conversion Agent during the period from, and including, the date on which
the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) up to, and
including, the Business Day immediately prior to the related Fundamental Change Purchase Date (or,
in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for
the proviso in clause (2) of the definition thereof, the 35th Trading Day immediately following the
Effective Date).

54

 

     (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change,
the Company shall deliver shares of Common Stock, including the Additional Shares, as provided
under Section 7.03. If the consideration for the shares of Common Stock in any Make-Whole
Fundamental Change described in clause (2)(A) of the definition of Fundamental Change is comprised
entirely of cash, for any conversion of the Notes following the Effective Date, the conversion
obligation will be calculated based solely on the Share Price for the transaction and will be
deemed to be, per $1,000 Principal Amount of Notes, an amount equal to the Applicable Conversion Rate (including any adjustment as described in
this Section 7.07) multiplied by such Share Price.

     (c) The number of Additional Shares, if any, by which the Conversion Rate will be increased
will be determined by reference to the table attached as Schedule A hereto, based on the
Effective Date and the price (the “Share Price”) paid (or deemed paid) per share of Common Stock in
the Make-Whole Fundamental Change. If the holders of the shares of Common Stock receive only cash
in a Make-Whole Fundamental Change described in clause (2)(A) of the definition of Fundamental
Change, the Share Price shall be the cash amount paid per share of Common Stock. Otherwise, the
Share Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Effective Date of such Make-Whole Fundamental Change.

     (d) The Share Prices set forth in the column headings of the table in Schedule A
hereto shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise
adjusted. The adjusted Share Prices shall equal the Share Prices immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately
prior to such adjustment giving rise to the Share Price adjustment and the denominator of which is
the Conversion Rate as so adjusted. The number of Additional Shares set forth in such table shall
be adjusted in the same manner as the Conversion Rate as set forth in Section 7.04.

     (e) The exact Share Prices and Effective Dates may not be set forth in the table in
Schedule A, in which case:

     (i) If the Share Price is between two Share Prices in the table or the Effective Date
is between two Effective Dates in the table, the number of Additional Shares by which the
Conversion Rate will be increased will be determined by a straight-line interpolation
between the number of Additional Shares set forth for the higher and lower Share Prices and
the earlier and later Effective Dates, as applicable, based on a 365-day year.

     (ii) If the Share Price is greater than $100.00 per share (subject to adjustment in the
same manner and at the same time as the Share Prices pursuant to Section 7.07(d)), no
Additional Shares will be added to the Conversion Rate.

     (iii) If the Share Price is less than $14.24 per share (subject to adjustment in the
same manner and at the same time as the Share Prices pursuant to Section 7.07(d)), no
Additional Shares will be added to the Conversion Rate.

55

 

     Notwithstanding the foregoing, in no event shall the Conversion Rate exceed 70.2246 shares of
Common Stock per $1,000 Principal Amount of Notes, subject to adjustments in the same manner as the
Conversion Rate as set forth in Section 7.04.

     (f) If a Holder of Notes elects to convert its Notes prior to the Effective Date, such Holder
shall not be entitled to an increased Conversion Rate in connection with such conversion.

     (g) The Company shall notify Holders of the anticipated Effective Date and issue a press
release announcing such Effective Date as soon as practicable after it determines the Effective
Date, but in no event later than five Business Days after such Effective Date; provided that if the
Company does not have knowledge of such transaction within five Business Days of the Effective
Date, no later than five Business Days after the date upon which the Company receives notice, or
otherwise becomes aware, of such transaction.

     Section 7.08 Taxes on Shares Issued. Any issue of share certificates on conversions of
Notes shall be made without charge to the converting Holder for any documentary, transfer, stamp or
any similar tax in respect of the issue thereof, and the Company shall pay any and all documentary,
stamp or similar issue or transfer taxes or duties that may be payable in respect of the issue or
delivery of shares of Common Stock on conversion of Notes pursuant hereto. The Company shall not,
however, be required to pay any such tax which may be payable in respect of any transfer involved
in the issue and delivery of shares in any name other than that of the Holder of any Notes
converted, and the Company shall not be required to issue or deliver any such share certificate
unless and until the Person or Persons requesting the issue thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the Company that such tax
has been paid.

     Section 7.09 Reservation of Shares; Shares to be Fully Paid; Compliance with Governmental
Requirements. The Company shall provide, free from preemptive rights, out of its authorized
but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for
the conversion of the Notes from time to time as such Notes are presented for conversion (assuming
that, at the time of the computation of such number of shares or securities, all such Notes would
be held by a single Holder).

     Before taking any action that would cause an adjustment increasing the Conversion Rate to an
amount that would cause the Conversion Price to be reduced below the then par value, if any, of the
shares of Common Stock issuable upon conversion of the Notes, the Company will take all corporate
action which may, in the opinion of its counsel, be necessary in order that the Company may validly
and legally issue shares of such shares of Common Stock at such adjusted Conversion Price.

     The Company covenants that all shares of Common Stock that may be issued upon conversion of
Notes shall be newly issued shares or treasury shares, shall be duly authorized, validly issued,
fully paid and non-assessable and shall be free from preemptive rights and free from any lien or
adverse claim.

56

 

     The Company shall use its reasonable efforts to list or cause to have quoted any shares of
Common Stock to be issued upon conversion of Notes on each national securities exchange or
over-the-counter or other domestic market on which the Common Stock is then listed or quoted.

     Section 7.10 Responsibility of Trustee and Conversion Agent . The Trustee and any other Conversion Agent shall not at any time be under any duty or
responsibility to any Holder to determine the Conversion Rate or whether any facts exist which may
require any adjustment of the Conversion Rate, or with respect to the nature or extent or
calculation of any such adjustment when made, or with respect to the method employed, or herein or
in any supplemental indenture provided to be employed, in making the same. The Trustee and any
other Conversion Agent shall not be accountable with respect to the validity or value (or the kind
or amount) of any Common Stock, or of any securities or property, which may at any time be issued
or delivered upon the conversion of any Notes; and the Trustee and any other Conversion Agent make
no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be
responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock
or share certificates or other securities or property or cash upon the surrender of any Notes for
the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the
Company contained in this Article 7. Without limiting the generality of the foregoing, neither the
Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of
any provisions contained in any supplemental indenture entered into pursuant to Section 7.05
relating either to the kind or amount of shares of stock or securities or property (including cash)
receivable by Holders upon the conversion of their Notes after any event referred to in such
Section 7.05 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 11.01, may accept as conclusive evidence of the correctness of any such provisions, and
shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated
to file with the Trustee prior to the execution of any such supplemental indenture) with respect
thereto.

     Section 7.11 Notice to Holders Prior to Certain Actions. In case:

     (a) the Company shall declare a dividend (or any other distribution) on Common Stock that
would require an adjustment in the Conversion Rate pursuant to Section 7.04; or

     (b) the Company shall authorize the granting to the holders of all or substantially all of the
shares of Common Stock of options, rights or warrants to subscribe for or purchase any share of any
class or any other options, rights or warrants; or

     (c) of any reclassification or reorganization of the Common Stock (other than a subdivision or
combination of its outstanding Common Stock, or a change in par value, or from par value to no par
value, or from no par value to par value), or of any consolidation or merger to which the Company
is a party and for which approval of any shareholders of the Company is required, or of the sale,
lease or transfer of all or substantially all of the assets of the Company; or

     (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company or
any of its Significant Subsidiaries;

57

 

then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent
and to be mailed to each Holder at such Holder’s address appearing on the list of Holders provided
for in Section 3.06 of this Indenture, as promptly as practicable, a notice stating (x) the
date on which a record is to be taken for the purpose of such dividend, distribution or rights or
warrants, or, if a record is not to be taken, the date as of which the holders of shares of Common
Stock of record to be entitled to such dividend, distribution or rights are to be determined, or
(y) the date on which such reclassification, reorganization, consolidation, merger, sale, lease,
transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the
date as of which it is expected that holders of shares of Common Stock of record shall be entitled
to exchange their shares of Common Stock for securities or other property deliverable upon such
reclassification, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation
or winding up. Failure to give such notice, or any defect therein, shall not affect the legality
or validity of such dividend, distribution, reclassification, reorganization, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up.

     Section 7.12 Shareholder Rights Plan. Each share of Common Stock issued upon conversion of
Notes pursuant to this Article 7 shall be entitled to receive the appropriate number of rights, if
any, and the certificates representing the shares of Common Stock issued upon such conversion shall
bear such legends, if any, in each case as may be provided by the terms of any shareholder rights
agreement adopted by the Company, as any such agreement may be amended from time to time.
Notwithstanding the foregoing, if prior to any conversion such rights have separated from the
Common Stock in accordance with the provisions of the applicable shareholder rights agreement, the
Conversion Rate shall be adjusted at the time of separation as if the Company had distributed, to
all holders of the Common Stock, Distributed Property as described in Section 7.03(c) above,
subject to readjustment in the event of the expiration, termination or redemption of such rights.

     Section 7.13 Company Determination Final. Any determination that the Company or its Board
of Directors must make pursuant to this Article 7 shall be conclusive if made in good faith and in
accordance with the provisions of this Article 7, absent manifest error, and set forth in a Board
Resolution.

ARTICLE 8

PURCHASE AT OPTION OF HOLDERS UPON A FUNDAMENTAL CHANGE

     Section 8.01 Purchase at Option of Holders upon a Fundamental Change.

     (a) Generally. If a Fundamental Change occurs at any time prior to the Maturity Date
of the Notes, then each Holder shall have the right, at such Holder’s option to require the Company
to purchase any or all of such Holder’s Notes or any portion thereof that is equal to $1,000 or an
integral multiple of $1,000 in excess thereof, on a date specified by the Company that is no
earlier than the 15th and not later than the 35th calendar day following the date of the
Fundamental Change Company Notice, subject to extension to comply with applicable law (the
“Fundamental Change Purchase Date”), at a purchase price in cash equal to 100% of the Principal
Amount thereof, together with accrued and unpaid interest thereon to, but excluding, the
Fundamental Change Purchase Date or, in the case of a Default by the Company in the payment of the
Fundamental Change Purchase Price with respect to such Notes, the day on

58

 

which such Default is no longer continuing (the “Fundamental Change Purchase Price”);
provided, however, if the Fundamental Change Purchase Date occurs after a Regular Record Date and
on or prior to the Interest Payment Date to which it relates, the Company will pay accrued and
unpaid interest to the Holder of record on such Regular Record Date.

     Purchases of Notes under this Section 8.01 shall be made, at the option of the Holder thereof
upon:

     (i) delivery to the Paying Agent of a duly completed notice (the “Fundamental Change
Purchase Notice”) in the form set forth on the reverse of the Notes on or prior to the
Business Day immediately preceding the Fundamental Change Purchase Date, subject to
extension to comply with applicable law, which must specify:

     (A) if the Notes are Physical Notes, the certificate numbers of the Holder’s
Notes to be delivered for purchase;

     (B) the portion of the Principal Amount of the Holder’s Notes to be purchased,
which must be $1,000 or an integral multiple in excess thereof; and

     (C) that the Holder’s Notes are to be purchased by the Company pursuant to the
applicable provisions of the Notes and this Indenture; and

     (ii) delivery or book-entry transfer of the Notes to the Trustee (or other Paying Agent
appointed by the Company) (together with all necessary endorsements) at any time on or prior
to the Business Day immediately preceding the Fundamental Change Purchase Date, subject to
extension to comply with applicable law, at the applicable Corporate Trust Office of the
Trustee (or other Paying Agent appointed by the Company), such delivery being a condition to
receipt by the Holder of the Fundamental Change Purchase Price therefor; provided that such
Fundamental Change Purchase Price shall be so paid pursuant to this Section 8.01 only if the
Notes so delivered to the Trustee (or other Paying Agent appointed by the Company) shall
conform in all respects to the description thereof in the related Fundamental Change
Purchase Notice; provided that, if such Holder’s Notes are not Physical Notes, such Holder
must comply with the Applicable Procedures.

     Any purchase by the Company contemplated pursuant to the provisions of this Section 8.01 shall
be consummated by the delivery of the Fundamental Change Purchase Price to be received by the
Holder promptly following the later of the Fundamental Change Purchase Date or the time of the
book-entry transfer or delivery of the Notes.

     Notwithstanding anything herein to the contrary, any Holder delivering to the Trustee (or
other Paying Agent appointed by the Company) the Fundamental Change Purchase Notice contemplated by
this Section 8.01 shall have the right to withdraw such Fundamental Change Purchase Notice (in
whole or in part) at any time prior to the Close of Business on (i) the Business Day prior to the
Fundamental Change Purchase Date or (ii) in the case of a Default by the Company in the payment of
the Fundamental Change Purchase Price with respect to such Notes, the Business Day immediately
preceding the day on which such Default is no longer

59

 

continuing, in either case, by delivery of a written notice of withdrawal to the Trustee (or
other Paying Agent appointed by the Company) in accordance with Section 8.03 below.

     The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental
Change Purchase Notice or written notice of withdrawal thereof.

     (b) Fundamental Change Company Notice. Subject to Section 8.08, on or before the 20th
day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of
record of the Notes and the Trustee and Paying Agent a notice (the “Fundamental Change Company
Notice”) of the occurrence of such Fundamental Change and of the purchase right at the option of
the Holders arising as a result thereof. Such mailing shall be by first class mail.
Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish a
notice containing the information included therein once in a newspaper of general circulation in
The City of New York or publish such information on the Company’s website or through such other
public medium as the Company may use at such time.

     Each Fundamental Change Company Notice shall specify:

     (i) the events causing the Fundamental Change;

     (ii) the date of the Fundamental Change;

     (iii) whether the fundamental change is a Make-Whole Fundamental Change, and the last
day on which a Holder may convert in connection with the Make-Whole Fundamental Change;

     (iv) the last date on which a Holder may exercise the purchase right;

     (v) the Fundamental Change Purchase Price;

     (vi) the Fundamental Change Purchase Date;

     (vii) the name and address of the Paying Agent and the Conversion Agent, if applicable;

     (viii) if applicable, the Applicable Conversion Rate and any adjustments to the
Applicable Conversion Rate;

     (ix) if applicable, that the Notes with respect to which a Fundamental Change Purchase
Notice has been delivered by a Holder may be converted only if the Holder withdraws the
Fundamental Change Purchase Notice in accordance with Section 8.03; and

     (x) the procedures that Holders must follow to require the Company to purchase their
Notes.

60

 

     No failure of the Company to give the foregoing notices and no defect therein shall limit any
Holder’s purchase rights or affect the validity of the proceedings for the purchase of the Notes
pursuant to this Section 8.01.

     (c) No Payment During an Acceleration. Notwithstanding the foregoing, no Notes may be
purchased by the Company at the option of the Holders pursuant to this Section 8.01 if the
Principal Amount of the Notes has been accelerated, and such acceleration has not been rescinded,
on or prior to the Fundamental Change Purchase Date (except in the case of an acceleration
resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price
with respect to such Notes).

     (d) Payment of Fundamental Change Purchase Price. The Notes to be purchased pursuant
to this Section 8.01 shall be paid for in cash.

     Section 8.02 Effect of Fundamental Change Purchase Notice. Upon receipt by the Paying
Agent of the Fundamental Change Purchase Notice specified in Section 8.01(a), the Holder of the
Note in respect of which such Fundamental Change Purchase Notice was given shall (unless such
Fundamental Change Purchase Notice is withdrawn as specified in Section 8.03) thereafter be
entitled to receive solely the Fundamental Change Purchase Price with respect to such Note. Such
Fundamental Change Purchase Price shall be payable to such Holder promptly following the later of
(x) the Fundamental Change Purchase Date with respect to such Note (provided the conditions in
Section 8.01(a) have been satisfied) and (y) the time of delivery or book-entry transfer of such
Note to the Paying Agent by the Holder thereof in the manner required by Section 8.01(a).

     Section 8.03 Withdrawal of Fundamental Change Purchase Notice.

     (a) A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a
written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental
Change Company Notice prior to the Close of Business on (i) the Business Day immediately preceding
the relevant Fundamental Change Purchase Date or (ii) in the case of a Default by the Company in
the payment of the Fundamental Change Purchase Price with respect to such Notes, the Business Day
immediately preceding the day on which such Default is no longer continuing, specifying:

     (i) the Principal Amount of the withdrawn Notes;

     (ii) if the Notes are Physical Notes, the certificate numbers of the withdrawn Notes;
and

     (iii) the Principal Amount, if any, of such Notes that remains subject to the original
Fundamental Change Purchase Notice, which must be $1,000 or an integral multiple of $1,000
in excess thereof;

provided that, if such Holder’s Notes are not Physical Notes, such Holder must comply with the
Applicable Procedures.

     Section 8.04 Deposit of Fundamental Change Purchase Price. Prior to 10:00 a.m. (local time
in The City of New York) on the Fundamental Change Purchase Date, the Company shall deposit with
the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as
the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in
immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental
Change Purchase Price, of all the Notes or portions thereof that are to be purchased as of the
Fundamental Change Purchase Date. The Company shall promptly notify the Trustee in writing of the
amount of any deposits of cash made pursuant to this Section 8.04. If the Paying Agent holds money
sufficient to pay the Fundamental Change Purchase Price of any Note surrendered for purchase and
not withdrawn in accordance with this Indenture as of the Close of Business on the Fundamental
Change Purchase Date, then immediately following the Close of Business on the Fundamental Change
Purchase Date, (a) any such Note will cease to be outstanding and interest will cease to accrue
thereon on the Fundamental Change Purchase Date (whether or not book-entry transfer of the Notes is
made or whether or not the Notes are delivered to the Paying Agent) and (b) all other rights of the
Holder in respect thereof will terminate (other than the right to receive the Fundamental Change
Purchase Price and previously accrued and unpaid interest (including Additional Interest, if any)
upon delivery or book-entry transfer of such Note).

     Section 8.05 Notes Purchased in Whole or in Part. Any Note that is to be purchased,
whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s
attorney duly authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes,
of any authorized denomination as requested by such Holder in aggregate Principal Amount equal to,
and in exchange for, the portion of the Principal Amount of the Note so surrendered which is not
purchased.

     Section 8.06 Covenant to Comply With Securities Laws upon Purchase of Notes. In connection
with any offer to purchase Notes under Section 8.01, the Company shall, if required:

     (a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other of the tender offer
rules under the Exchange Act that may then be applicable;

     (b) file a Schedule TO or any other required schedule under the Exchange Act; and

     (c) otherwise comply with all federal and state securities laws in connection with any offer
by the Company to purchase the Notes.

     Section 8.07 Repayment to the Company . Subject to the requirements of any applicable abandoned property laws, regardless of who acts as
Paying Agent, the Paying Agent shall return to the Company any cash that remains unclaimed,
together with interest, if any, thereon, held by them for the payment of the Fundamental Change
Purchase Price; provided that to the extent that the aggregate amount of cash deposited by the
Company pursuant to Section 8.04 exceeds the aggregate Fundamental Change Purchase Price of the
Notes or portions thereof which the Company is obligated to purchase as of the Fundamental Change
Purchase Date, then

62

 

as soon as practicable following the Fundamental Change Purchase Date, the
Paying Agent shall return any such excess to the Company.

     Section 8.08 Payment or Consent for Other Secured Indebtedness. Notwithstanding the
foregoing, prior to the Company’s delivery of a Fundamental Change Purchase Notice pursuant to
Section 8.01 and prior to any purchase of Notes by the Company contemplated pursuant to Section
8.01, the Company or any Guarantor must either repay in full in cash or obtain the requisite
consents to purchase the Notes under the 15% Term Loan and any other senior secured Indebtedness of
the Company or any Guarantor requiring such consent or repayment.

64

 

     The Trustee shall not be charged with knowledge of any Event of Default unless written notice
thereof shall have be given to a Trust Officer at the Corporate Trust Office of the Trustee by the
Company’s Paying Agent or any Holder.

     Section 9.02 Acceleration of Maturity: Waiver of Past Defaults and Rescission.

     (a) If an Event of Default (other than those specified in Sections 9.01(i) and 9.01(j)
involving the Company, and as otherwise provided in Section 9.03) occurs and is continuing, then
and in every such case the Trustee or the Holders of not less than 25% in aggregate Principal
Amount of the outstanding Notes may, and the Trustee at the request of such Holders shall, declare
100% of the Principal Amount plus accrued and unpaid interest on all the outstanding Notes to be
due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by
Holders), and upon any such declaration such Principal Amount plus accrued and unpaid interest
shall become immediately due and payable.

     Notwithstanding the foregoing, in the case of an Event of Default specified in Section 9.01(i)
or Section 9.01(j) with respect to the Company (but not with respect to any Significant Subsidiary
of the Company or any group of Subsidiaries of the Company that, in the aggregate, would constitute
a Significant Subsidiary of the Company), 100% of the Principal Amount plus accrued and unpaid
interest on all outstanding Notes will automatically become 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 the Trustee, may (x) waive any past Default and its consequences
and (y) at any time after a declaration of acceleration has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article
9 provided, rescind any such acceleration with respect to the Notes and its consequences, except,
in each case, with respect to a Default described in Section 9.01(a), Section 9.01(b) or Section
9.01(c), or in respect of a covenant or provision hereof which under Article 14 cannot be modified
or amended without the consent of the Holder of each outstanding Note affected, if:

     (i) such rescission will not conflict with any judgment or decree of a court of
competent jurisdiction; and

     (ii) all existing Events of Default (other than the non-payment of any Principal Amount
or interest that became due solely by such declaration of acceleration) have been cured or
waived.

     Upon any such waiver, the Default which has been waived shall cease to exist and any Event of
Default arising therefrom shall be deemed to have been cured, for every other purpose of the
Indenture; but not such waiver shall extend to any subsequent or other Default or impair any right
consequent.

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

     Section 9.03 Additional Interest.

65

 

     (a) If, at any time during the six-month period beginning on, and including, the date which is
six months after the last date of original issuance of any of the Initial Notes, the Company fails
to timely file any document or report that the Company is required to file with the Commission
pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all
applicable grace periods thereunder and other than current reports on Form 8-K), or the Notes are
not otherwise Freely Tradable (as a result of restrictions pursuant to U.S. securities law or the
terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes,
which shall accrue at the rate of 0.50% per annum of the Principal Amount of Notes outstanding for
each day during such period for which the Company’s failure to file has occurred and is continuing
or for which the Notes are not Freely Tradable (ending on the date that is one year from the last
date of original issuance of any of the Initial Notes); provided that, notwithstanding anything to
the contrary in this Indenture, during the six-month period beginning on, and including, the date
which is six months after the last date of original issuance of any of the Initial Notes, in no
event shall the aggregate amount of Additional Interest payable pursuant to this paragraph and
pursuant to Section 9.03(b) exceed 0.50% per annum.

     Further, if, and for so long as, the Restrictive Notes Legend has not been removed from the
Notes, the Notes are assigned a restricted CUSIP number or the Notes are not otherwise Freely
Tradable as of the 366th day after the last date of original issuance of any of the Initial Notes,
the Company shall pay Additional Interest on the Notes. Such Additional Interest will accrue on
the Notes at the rate of 0.50% per annum of the Principal Amount of Notes outstanding until the
Restrictive Notes Legend has been removed in accordance with Section 3.08, the Notes are assigned
an unrestricted CUSIP number and the Notes are Freely Tradable.

     The obligations of the Company pursuant to this Section 9.03(a) are separate and distinct
from, and in addition to, the obligations of the Company pursuant to Section 9.03(b), subject to
proviso to the first paragraph of this Section 9.03(a). Any Additional Interest payable pursuant
to this Section 9.03(a) will be payable in arrears on each Interest Payment Date following accrual
in the same manner as ordinary interest is payable pursuant to Section 2.03.

     (b) Notwithstanding anything to the contrary in this Indenture, if so elected by the Company,
the sole remedy for an Event of Default relating to the failure to comply with Section
4.10 hereof will (i) for the first 90 days after the occurrence of such an Event of Default
consist exclusively of the right to receive Additional Interest on the Notes at an annual rate
equal to 0.25% of the Principal Amount of outstanding Notes and (ii) from the 91st day until the
180th day following the occurrence of such an Event of Default consist exclusively of the right to
receive Additional Interest on the Notes at an annual rate equal to 0.50% of the Principal Amount
of outstanding Notes. The Additional Interest payable pursuant to this Section 9.03(b) will be in
addition to any Additional Interest that may accrue pursuant to Section 9.03(a) (subject to the
proviso to the first paragraph of such Section). If the Company so elects, the Additional Interest
payable under this Section 9.03(b) will be payable on all outstanding Notes from and including the
date on which such Event of Default first occurs to and including the 180th day thereafter, or such
earlier date on which such Event of Default has been cured or waived or ceases to exist. On the
181st day after such Event of Default, if such Event of Default has not been cured or waived prior
to such 181st day, Additional Interest payable pursuant to this Section 9.03(b) will cease to
accrue and the Notes will be subject to acceleration as provided in Section 9.02. In the event the
Company does not elect to pay the Additional Interest payable

66

 

pursuant to this Section 9.03(b) upon an Event of Default in accordance with this paragraph, the Notes will be subject to acceleration as
provided in Section 9.02. Any Additional Interest payable pursuant to this Section 9.03(b) will be
payable in arrears on each Interest Payment Date following accrual in the same manner as ordinary
interest is payable pursuant to Section 2.03.

     In order to elect to pay the Additional Interest payable pursuant to this Section 9.03(b) as
the sole remedy during the first 180 days after the occurrence of an Event of Default relating to
the failure to comply with Section 4.10 in accordance with the immediately preceding paragraph, the
Company must notify all Holders, the Trustee and Paying Agent of such election on or before the
Close of Business on the date on which such Event of Default first occurs. Upon the failure to
timely give all Holders, the Trustee and Paying Agent such notice, the Notes will be immediately
subject to acceleration as provided in Section 9.02.

     Section 9.04 Collection of Indebtedness and Suits for Enforcement by Trustee. The Company
covenants that if a Default is made in the payment of the Principal Amount plus accrued and unpaid
interest on the Maturity Date therefor or in the payment of the Fundamental Change Purchase Price
in respect of any Note, the Company will, upon demand of the Trustee, pay to it, for the benefit of
the Holders of such Notes, the whole amount then due and payable on such Notes, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel.

     If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated
to, pursue any available remedy to collect the payment of the Principal Amount plus accrued but
unpaid interest on the Notes or to enforce the performance of any provision of the Notes or this
Indenture. The Trustee may maintain a proceeding even if the Trustee does not possess any of the
Notes or does not produce any of the Notes in the proceeding. A delay or omission by the Trustee
or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair
the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No remedy
is exclusive of any other remedy. All available remedies are cumulative.

     Section 9.05 Trustee May File Proofs of Claim. In case of any judicial proceeding relative
to the Company (or any other obligor upon the Notes), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and
all actions authorized under this Indenture and applicable law in order to have claims of the
Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be
authorized to collect and receive any moneys or other property payable or deliverable on any such
claims and to distribute the same; and 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, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel and any other amounts due the Trustee under Section 11.07.

     No provision of this Indenture shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,

67

 

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 9.06 Application of Money Collected. Any money collected by the Trustee pursuant
to this Article shall be applied in the following order, at the date or dates fixed by the Trustee
and, in case of the distribution of such money to Holders, upon presentation of the Notes and the
notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 11.07;

     SECOND: To the payment of the amounts then due and unpaid on the Notes for the Principal
Amount, Fundamental Change Purchase Price, or interest (including Additional Interest, if any) as
the case may be, in respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts due and payable on
such Notes; and

     THIRD: To the payment of the remainder, if any, to the Company or any other Person lawfully
entitled thereto.

     Section 9.07 Limitation on Suits. No Holder of any Note shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, the Notes, the Subsidiary
Guarantees or for the appointment of a receiver or trustee, or for any other remedy hereunder
(other than in the case of an Event of Default specified in Section 9.01(a), Section 9.01(b) or
Section 9.01(c)) unless:

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

     (ii) the Holder or Holders of not less than 25% in aggregate Principal Amount of the
outstanding Notes shall have made written request to the Trustee to institute proceedings in
respect of such Event of Default in is own name as Trustee hereunder;

     (iii) such Holder or Holders have offered to the Trustee security or indemnity
reasonably satisfactory to it against any loss, liability or expense;

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

     (v) no direction, in the opinion of the Trustee, inconsistent with such written request
has been given to the Trustee during such 60-day period by the Holders of a majority in
aggregate Principal Amount of the outstanding Notes;

it being understood and intended that no one or more Holders shall have any right in any manner
whatever by virtue of, or by availing itself of, any provision of this Indenture to affect, disturb
or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or
preference over any other Holders or to enforce any right under this Indenture, except in the
manner herein provided and for the equal and ratable benefit of all the Holders.

68

 

     Section 9.08 Unconditional Right of Holders to Receive Payment. Notwithstanding any other
provision of this Indenture, the right of any Holder to receive payment of the Principal Amount
(including the Fundamental Change Purchase Price or interest in respect of the Notes held by such
Holder, on or after the respective due dates expressed in the Notes, or any Fundamental Change
Purchase Date or otherwise, as applicable), any accrued and unpaid interest (including Additional
Interest, if any) and to convert the Notes in accordance with Article 7, or to bring suit for the
enforcement of any such payment on or after such respective dates or the right to convert, shall
not be impaired or affected without the consent of such Holder.

     Section 9.09 Restoration of Rights and Remedies. If the Trustee or any Holder has
instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding
has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee
or to such Holder, then and in every such case, subject to any determination in such proceeding,
the Company, the Trustee and the Holders shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

     Section 9.10 Rights and Remedies Cumulative. Except as otherwise provided with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of
Section 3.09, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders
is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder shall not prevent the concurrent assertion or employment of any other appropriate right
or remedy.

     Section 9.11 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any
Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall 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.

     Section 9.12 Control by Holders. 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 of exercising any trust or power conferred on the Trustee.
However, the Trustee may refuse to follow any direction that conflicts with applicable law or this
Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or
that would involve the Trustee in personal liability. Prior to taking any action under this
Indenture, the Trustee will be entitled to indemnification satisfactory to it in its sole
discretion against all losses and expenses caused by taking or not taking such action.

     Section 9.13 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, in either case in respect of the Notes, a court may require any party litigant in such
suit to file an undertaking to pay the costs of the suit, and the court may assess reasonable
costs,

69

 

including reasonable attorney’s fees and expenses, against any party litigant in the suit
having due regard to the merits and good faith of the claims or defenses made by the party
litigant; but the provisions of this Section 9.13 shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in Principal Amount of the outstanding Notes, or to
any suit instituted by any Holder for the enforcement of the payment of the Principal Amount on any
Note on or after the Maturity Date of such Note or the Fundamental Change Purchase Date.

     Section 9.14 [Reserved.]

     Section 9.15 Violations of Certain Covenants. A violation of Section 4.10 or any other
covenant or agreement in this Indenture that expressly provides that a violation of such covenant
or agreement shall not constitute an Event of Default may only be enforced by the Trustee by
instituting a legal proceeding against the Company for enforcement of such covenant or agreement.

ARTICLE 10

MERGER, CONSOLIDATION OR SALE OF ASSETS

     Section 10.01 Company May Consolidate, etc., only on Certain Terms. The Company shall not,
in a single transaction or through a series of related transactions, consolidate or merge with or
into any other Person, or, directly or indirectly, sell, convey, transfer, lease or otherwise
dispose of all or substantially all of Company’s assets to another Person or group of affiliated
Persons, except that the Company may consolidate or merge with or into, or sell, convey, transfer,
lease or otherwise dispose of all or substantially all of its assets to another Person if:

     (i) the Company is the surviving Person or the resulting, surviving, transferee or
successor Person (the “Successor Entity”) (if other than the Company) is a corporation or
other legal entity organized and existing under the laws of the United States of America,
any State of the United States of America or the District of Columbia and such Successor
Entity (if not the Company) expressly assumes by an indenture supplemental hereto all
obligations of the Company under this Indenture, including payment of the Principal Amount
and interest on the Notes, and the performance and observance of all of the covenants of
this Indenture to be performed by the Company;

     (ii) immediately after giving effect to such transaction, no Default or Event of
Default under this Indenture has occurred and is continuing;

     (iii) if, upon the occurrence of any such consolidation, merger, sale, conveyance,
transfer, lease or other disposal, (x) the Notes would become convertible pursuant to the
terms of this Indenture into securities issued by an issuer other than the Successor Entity,
and (y) such Successor Entity is a wholly owned subsidiary of the issuer of such securities
into which the Notes have become convertible, such other issuer shall fully and
unconditionally guarantee on a senior basis the Successor Entity’s obligations under the
Notes; and

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

70

 

transfer lease or other disposal and, if a supplemental indenture is required in connection with such
transaction, such supplemental indenture, comply with this Article 10 and that all
conditions precedent herein provided for relating to such transaction have been satisfied.

     Section 10.02 Successor Substituted. Upon any consolidation of the Company with, or merger
of the Company into, any other Person or any sale, conveyance, transfer, lease or other disposal of
all or substantially all of the Company’s assets to another Person in accordance with Section
10.01, the Successor Entity formed by such consolidation or into which the Company is merged or to
which such sale, conveyance, transfer, lease or other disposal is made shall succeed to, and may
exercise every right and power of, the Company under this Indenture with the same effect as if such
Successor Entity had been named as the Company herein. If the predecessor is still in existence
after such transaction, it will be released from its obligations and covenants under this indenture and the
Notes, except in the case of a lease of all or substantially all of its assets.

ARTICLE 11

THE TRUSTEE

     Section 11.01 Duties and Responsibilities of Trustee.

     (a) The Trustee, prior to the occurrence of an Event of Default and after the curing of all
Events of Default which may have occurred, undertakes to perform such duties and only such duties
as are specifically set forth in this Indenture. In case an Event of Default has occurred (which
has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent
person would exercise or use under the circumstances in the conduct of his own affairs.

     (b) 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,
except that:

     (i) prior to the occurrence of an Event of Default and after the curing or waiving of
all Events of Default which may have occurred:

     (A) the duties and obligations of the Trustee shall be determined solely by the
express provisions of this Indenture and applicable law, and the Trustee shall not
be liable except for the performance of such duties and obligations as are
specifically set forth in this Indenture and no implied covenants or obligations
shall be read into this Indenture against the Trustee; and

     (B) in the absence of bad faith and willful misconduct on the part of the
Trustee, the Trustee may conclusively rely as to the truth of the statements and the

     Section 11.07 Compensation and Expenses of Trustee. The Company covenants and agrees to

after an Event of Default specified in Section 9.01(i) or Section 9.01(j) with respect to the
Company occurs, the expenses and the compensation for the services are intended to constitute

applicable.

     Section 11.08 Officers’ Certificate as Evidence. Except as otherwise provided in Section
11.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or omitting any

prescribed) may, in the absence of negligence or willful misconduct on the part of the Trustee, be
deemed to be conclusively proved and established by an Officers’ Certificate delivered to the
Trustee.

     Section 11.09 Conflicting Interests of Trustee. If the Trustee has or shall acquire a
conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest within 90 days or resign, to the extent and in the manner provided by, and
subject to the provisions of, this Indenture.

     Section 11.10 Eligibility of Trustee. There shall at all times be a Trustee hereunder
which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has
a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank
holding company system, its bank holding company shall have a combined capital and surplus of at
least $50,000,000). If such Person publishes reports of condition at least annually, pursuant to
law or to the requirements of any supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such Person shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this Section 11.10, it
shall resign immediately in the manner and with the effect hereinafter specified in this Article.

     This Indenture shall always have a Trustee who satisfies the requirements of Trust Indenture
Act § 310(a)(1), (2) and (5). The Trustee is subject to Trust Indenture Act § 310(b).

     Section 11.11 Resignation or Removal of Trustee.

     (a) The Trustee may at any time resign by giving written notice of such resignation to the
Company and to the Holders of Notes. Upon receiving such notice of resignation, the Company shall
promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the
Company’s Board of Directors, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee. If no successor trustee shall have been so
appointed and have accepted appointment sixty (60) days after the mailing of such notice

75

 

of resignation to the Holders, the resigning Trustee may, upon ten (10) Business Days’ notice to the
Company and the Holders, appoint a successor identified in such notice or may petition, at the
expense of the Company, any court of competent jurisdiction for the appointment of a successor
trustee, or, if any Holder who has been a bona fide Holder of a Note or Notes for at least six (6)
months may, subject to the provisions of Section 9.13, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor
trustee.

     (b) In case at any time any of the following shall occur:

     (i) the Trustee shall fail to comply with Section 11.09 after written request therefor
by the Company or by any Holder who has been a bona fide Holder of a Note or Notes for at
least six (6) months; or

     (ii) the Trustee shall cease to be eligible in accordance with the provisions of
Section 11.10 and shall fail to resign after written request therefor by the Company or by
any such Holder; or

     (iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, executed by order of the Company’s Board of Directors, one copy
of which instrument shall be delivered to the Trustee so removed and one copy to the successor
trustee, or, subject to the provisions of Section 9.13, any Holder who has been a bona fide Holder
of a Note or Notes for at least six (6) months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor trustee; provided, however, that if no successor Trustee shall have been
appointed and have accepted appointment sixty (60) days after either the Company or the Holders has
removed the Trustee, the Trustee so removed may petition at its own expense any court of competent
jurisdiction for an appointment of a successor trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

     (c) The Holders of a majority in aggregate Principal Amount of the Notes at the time
outstanding may at any time remove the Trustee and nominate a successor trustee which shall be
deemed appointed as successor trustee unless, within ten (10) days after notice to the Company of
such nomination, the Company objects thereto, in which case the Trustee so removed or any Holder,
or if such Trustee so removed or any Holder fails to act, the Company, upon the terms and
conditions and otherwise as in Section 11.11(a) provided, may petition any court of competent
jurisdiction for an appointment of a successor trustee.

76

 

     (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant
to any of the provisions of this Section 9.11 shall become effective upon acceptance of appointment
by the successor trustee as provided in Section 11.12.

     Section 11.12 Acceptance by Successor Trustee. Any successor trustee appointed as provided
in Section 11.11 shall execute, acknowledge and deliver to the Company and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the resignation or
removal of the predecessor trustee shall become effective and such successor trustee, without any
further act, deed or conveyance, shall become vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally named as trustee
herein; but, nevertheless, on the written request of the Company or of the successor trustee, the
trustee ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of
Section 11.07, execute and deliver an instrument transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee,
the Company shall execute any and all instruments in writing for more fully and certainly vesting
in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act
shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as
such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any
amounts then due it pursuant to the provisions of Section 11.07.

     No successor trustee shall accept appointment as provided in this Section 11.12 unless, at the
time of such acceptance, such successor trustee shall be qualified under the provisions of Section
11.09 and be eligible under the provisions of Section 11.10.

     Upon acceptance of appointment by a successor trustee as provided in this Section 11.12, the
Company (or the former trustee, at the written direction of the Company) shall mail or cause to be
mailed notice of the succession of such trustee hereunder to the Holders of Notes at their
addresses as they shall appear on the Register. If the Company fails to mail such notice within
ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall
cause such notice to be mailed at the expense of the Company.

     Section 11.13 Succession by Merger, Etc. Any corporation into which the Trustee may be
merged or converted or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee (including any trust created by this Indenture), shall be
the successor to the Trustee hereunder without the execution or filing of any paper or any further
act on the part of any of the parties hereto, provided that in the case of any corporation
succeeding to all or substantially all of the corporate trust business of the Trustee, such
corporation shall be qualified under the provisions of Section 11.09 and eligible under the
provisions of Section 11.10.

     In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to
the Trustee may adopt the certificate of authentication of any predecessor trustee or
authenticating agent appointed by such predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been authenticated, any

77

 

successor to the Trustee or any authenticating agent appointed by such successor trustee may
authenticate such Notes in the name of the successor trustee; and in all such cases such
certificates shall have the full force that is provided in the Notes or in this Indenture;
provided, however, that the right to adopt the certificate of authentication of any predecessor
Trustee or authenticate Notes in the name of any predecessor Trustee shall apply only to its
successor or successors by merger, conversion or consolidation.

     Section 11.14 Preferential Collection of Claims. If and when the Trustee shall be or
become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be
subject to the provisions of § 311(a) of the Trust Indenture Act, excluding any creditor
relationship listed in § 311(b), regarding the collection of the claims against the Company (or any
such other obligor). A Trustee who has resigned or been removed shall be subject to § 311(a) to
the extent indicated therein.

     Section 11.15 Trustee’s Application for Instructions from the Company. Any application by
the Trustee for written instructions from the Company (other than with regard to any action
proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders
of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any
action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or
after which such action shall be taken or such omission shall be effective. The Trustee shall not
be liable for any action taken by, or omission of, the Trustee in accordance with a proposal
included in such application on or after the date specified in such application (which date shall
not be less than three (3) Business Days after the date any officer of the Company actually
receives such application, unless any such officer shall have consented in writing to any earlier
date) unless prior to taking any such action (or the effective date in the case of an omission),
the Trustee shall have received written instructions in response to such application specifying the
action to be taken or omitted.

of any conversion) shares of Common Stock on, the Notes and the other rights, duties and

the Trustee, on written demand of the Company accompanied by an Officers’ Certificate and an
Opinion of Counsel as required by Section 1.02 and at the cost and expense of the Company, shall
execute proper instruments acknowledging satisfaction of and discharging this Indenture; the
Company, however, hereby agrees to the Trustee for any costs or expenses thereafter reasonably and

on, such Holder’s Notes on or after the due dates therefor or to institute suit for the
enforcement of any payment on or with respect to such Holder’s Notes;

     (viii) change the ranking of the Notes or any Subsidiary Guarantee;

     (ix) release any Guarantor from any of its obligations under its Subsidiary Guarantee
or this Indenture otherwise than in accordance with this Indenture; or

     (x) modify any of the provisions of this Section 14.02 or Section 9.02(b).

     It shall not be necessary for any consent of Holders under this Section 14.02 to approve the
particular form of any proposed supplemental indenture, but it shall be sufficient if such act
shall approve the substance thereof.

     Section 14.03 Execution of Supplemental Indentures. In executing, or accepting the
additional trusts created by, any supplemental indenture permitted by this Article 14 or the
modifications thereby of the trusts created by this Indenture, the Trustee shall be provided with,
and (subject to Section 11.01) shall be fully protected in relying upon, in addition to the
documents required by Section 1.02, an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture. Subject to the preceding
sentence, the Trustee shall sign such supplemental indenture if the same does not adversely affect
the Trustee’s own rights, duties or immunities under this Indenture or otherwise. The Trustee may,
but shall not be obligated to, enter into any such supplemental indenture that adversely affects
the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

     Section 14.04 Effect of Supplemental Indentures. Upon the execution of any supplemental
indenture under this Article 14, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and every Holder
theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

82

 

     Section 14.05 [Reserved.]

     Section 14.06 Reference in Notes to Supplemental Indentures. Notes authenticated and
delivered after the execution of any supplemental indenture pursuant to this Article 14 shall bear
a notation in form approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company shall so determine, new Notes so modified as to conform, in the opinion
of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by
the Company and authenticated and delivered by the Trustee in exchange for outstanding Notes.

     Section 14.07 Notice to Holders of Supplemental Indentures. The Company shall cause notice
of the execution of any supplemental indenture pursuant to Section 14.02 to be mailed to each
Holder, at such Holder’s address appearing on the Register provided for in this Indenture, within
20 days after execution thereof. Failure to deliver such
notice, or any defect in such notice, shall not impair or affect the legality or validity of such
supplemental indenture.

ARTICLE 15

GUARANTEES OF NOTES

     Section 15.01 Subsidiary Guarantees. Subject to this Article 15, each of the Guarantors
hereby, jointly and severally, unconditionally guarantees, on a senior unsecured basis, to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors
and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the
obligations of the Company hereunder and thereunder, that:

     (a) the principal of, and interest on, each of the Notes will be promptly paid in full when
due, whether at stated maturity, by acceleration, upon repurchase or otherwise, and interest on the
overdue principal of and (to the extent permitted by law) interest and Additional Interest, if any,
on, the Notes, and all other payment obligations of the Company to the Holders or the Trustee under
this Indenture or the Notes will be promptly paid in full and performed, all in accordance with the
terms hereof and thereof; and

     (b) in case of any extension of time of payment or renewal of any Notes or any of such other
obligations, the same will be promptly paid in full when due or performed in accordance with the
terms of the extension or renewal, subject to any applicable grace period, whether at stated
maturity, by acceleration, upon repurchase or otherwise.

     Failing payment when so due of any amount so guaranteed for whatever reason, the Guarantors
will be jointly and severally obligated to pay the same immediately. An Event of Default under
this Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees,
and shall entitle the Holders to accelerate the obligations of the Guarantors hereunder in the same
manner and to the same extent as the obligations of the Company.

     The Guarantors hereby agree that their obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder with respect to any
provisions hereof or thereof, the recovery of any judgment against the Company, any action to
enforce the same or any other circumstance (other than complete performance) which might

83

 

otherwise
constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor further, to
the extent permitted by law, hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever and covenants that
its Subsidiary Guarantee will not be discharged except by complete performance of the obligations
contained in the Notes and this Indenture.

     If any Holder or the Trustee is required by any court or otherwise to return to the Company,
the Guarantors, or any custodian, Trustee or other similar official acting in relation to any of
the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee or
such Holder, the Subsidiary Guarantees, to the extent theretofore discharged, shall be
reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to
any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby
until payment in full of the obligations guaranteed hereby.

     Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the
Holders and the Trustee, on the other hand, (a) the maturity of the obligations guaranteed hereby
may be accelerated as provided in Article 9 hereof for the purposes of its Subsidiary Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect
of the obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of
such obligations as provided in Article 9 hereof, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary
Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor
so long as the exercise of such right does not impair the rights of the Holders under the
Subsidiary Guarantees.

     Section 15.02 Guarantors May Consolidate, etc., on Certain Terms.

     (a) A Guarantor will not, in a single transaction or through a series of related transactions,
consolidate or merge with or into any other Person, or, directly or indirectly, sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its assets to another Person or
group of affiliated Persons, other than the Company or another Guarantor, unless immediately after
giving effect to such transaction, no Default or Event of Default under this Indenture has occurred
and is continuing, and either (i) the Successor Entity (if other than the Guarantor) is a
corporation or other legal entity organized and existing under the laws of the United States of
America, any State of the United States of America or the District of Columbia and such Successor
Entity (if not the Guarantor) expressly assumes by supplemental indenture all obligations of the
Guarantor under its Subsidiary Guarantee and this Indenture, or (ii) the Subsidiary Guarantee of
such Guarantor is released as described in Section 15.03.

     (b) In the case of any such consolidation or merger and upon the assumption by the Successor
Entity, by supplemental indenture, executed and delivered to the Trustee and substantially in the
form of Annex A hereto, of the Subsidiary Guarantee of, and the due and punctual
performance of all of the covenants of this Indenture to be performed by, the applicable Guarantor,
such Successor Entity shall succeed to and be substituted for such Guarantor with the same effect
as if it had been named herein as a Guarantor.

84

 

     Section 15.03 Releases of Subsidiary Guarantees. The Subsidiary Guarantee of a Guarantor
shall be automatically and unconditionally released: (1) at such time as such Guarantor ceases to
guarantee any other Indebtedness of the Company or any other Guarantor in excess of the De Minimis
Guaranteed Amount (other than by reason of payment under any guarantee of any such Indebtedness);
(2) in connection with any sale or other disposition (including by way of merger or consolidation)
of the Capital Stock of such Guarantor to a Person that is not (either before or after giving
effect to such transaction) the Company or a Subsidiary of the Company, if the Guarantor no longer
qualifies as a Subsidiary as a result of
such disposition; (3) upon a sale or other disposition of all or substantially all of its assets;
or (4) upon satisfaction and discharge of this Indenture in accordance with Article 13.

     Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect that any
of the conditions described in the foregoing clauses (1) – (4) has occurred, the Trustee shall
execute any documents reasonably requested by the Company in order to evidence the release of any
Guarantor from its obligations under its Subsidiary Guarantee. Any Guarantor not released from its
obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of
and interest, premium, and Additional Interest, if any, on, the Notes and for the other obligations
of such Guarantor under this Indenture as provided in this Article 15.

     Further, the Subsidiary Guarantees with respect to a Note are not convertible and will
automatically terminate when that Note is converted in accordance with Article 7.

     Section 15.04 Limitation on Guarantor Liability. Each Guarantor, and by its acceptance of
Notes, each Holder, hereby confirms that it is the intention of all such parties that the
Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for
purposes of any bankruptcy law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary
Guarantee. The obligations of each Guarantor under its Subsidiary Guarantee will be limited to the
maximum amount as will, after giving effect to all other contingent and fixed liabilities of such
Guarantor and after giving effect to any collections from or payments made by or on behalf of any
other Guarantor in respect of the obligations of such other Guarantor under its Subsidiary
Guarantee or pursuant to its contribution obligations under this Indenture, result in the
obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent
conveyance or fraudulent transfer under federal or state law and not otherwise being void or
voidable under any similar laws affecting the rights of creditors generally.

     Section 15.05 “Trustee” to Include Paying Agent. In case at any time any Paying Agent
other than the Trustee shall have been appointed and be then acting hereunder, the term “Trustee”
as used in this Article 15 shall in each case (unless the context shall otherwise require) be
construed as extending to and including such Paying Agent within its meaning as fully and for all
intents and purposes as if such Paying Agent were named in this Article 15 in place of the Trustee.

85

duties shall control.

     The Company, any Guarantor or the Trustee by notice to the others may designate additional or

     Any notice or communication to a registered Holder shall be given in the manner provided in
Section 1.06. Any such notice or communication shall also be so mailed to any Person described in
Trust Indenture Act § 313(c), to the extent required by the Trust Indenture Act.

     The Trustee agrees to accept and act upon facsimile transmission of written instructions
and/or directions pursuant to this Indenture given by the Company, provided, however, that (i)

86

 

the Company, subsequent to such facsimile transmission of written instructions and/or directions, shall
provide the originally executed instructions and/or directions to the Trustee in a timely manner
and (ii) such originally executed instructions and/or directions shall be signed by an authorized
officer of the Company.

     Section 16.03 [Reserved.]

     Section 16.04 When Notes Are Disregarded. In determining whether the Holders of the
required Principal Amount of Notes have concurred in any direction, waiver or consent, Notes owned
by the Company or by any Affiliate of the Company shall be disregarded and deemed not to be
outstanding, except that, for the purpose of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Notes which a Trust Officer of the Trustee
actually knows are so owned shall be so disregarded. Also, subject to the foregoing, only Notes
outstanding at the time shall be considered in any such determination.

     Section 16.05 Rules by Trustee, Paying Agent and Registrar. The Trustee may make
reasonable rules for action by, or a meeting of, Holders. The Registrar and the Paying Agent may
make reasonable rules for their functions.

     Section 16.06 Legal Holidays. If an Interest Payment Date is a Legal Holiday, payment
shall be made on the next succeeding day that is not a Legal Holiday, and no interest shall accrue
for the intervening period. If a Regular Record Date is a Legal Holiday, the Regular Record Date
shall not be affected. In any case where the Maturity Date or Fundamental Change Purchase Date, as
the case may be, of any Note is a Legal Holiday, then (notwithstanding any other provision of this
Indenture or of the Notes) payment of principal need not be made on such date, but may be made on
the next succeeding day that is not a Legal Holiday, with the same force and effect as if made on
such Maturity Date or Fundamental Change Purchase Date, as the case may be.

     Section 16.07 Governing Law. THIS INDENTURE AND THE NOTES SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     Section 16.08 No Recourse against Others. An incorporator, director, officer, employee,
Affiliate or shareholder of the Company or any Guarantor, solely by reason of this status, shall
not have any liability for any obligations of the Company or any Guarantor under this Indenture,
the Notes or the Subsidiary Guarantees, or for any claim based on, in respect of or by reason of
such obligations or their creation. By accepting a Note, each Holder shall waive and release all
such liability. The waiver and release shall be part of the consideration for the issue of the
Notes.

     Section 16.09 Successors. All agreements of the Company and the Guarantors in this
Indenture and the Notes shall bind their respective successors. All agreements of the Trustee in
this Indenture shall bind its successors.

     Section 16.10 Multiple 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. One signed copy is enough to
prove this Indenture. Delivery of an executed

87

 

counterpart by facsimile shall be as effective as
delivery of a manually executed counterpart thereof.

     Section 16.11 [Reserved].

     Section 16.12 Table of Contents; Headings. The table of contents, cross-reference sheet
and headings of the Articles and Sections of this Indenture have been inserted for convenience of
reference only, are not intended to be considered a part hereof and shall not modify or restrict
any of the terms or provisions hereof.

     Section 16.13 Severability Clause. In case any provision in this Indenture shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby and such provision shall be
ineffective only to the extent of such invalidity, illegality or unenforceability.

     Section 16.14 Calculations. Except as otherwise provided herein, the Company (or its
agents) will be responsible for making all calculations called for under this Indenture or the
Notes. The Company (or its agents) will make all such calculations in good faith and, absent
manifest error, its calculations will be final and binding on Holders. The Company (or its agents)
upon request will provide a schedule of its calculations to each of the Trustee and the Conversion
Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the
accuracy of such calculations without independent verification. The Trustee will deliver a copy of
such schedule to any Holder upon the written request of such Holder.

     Section 16.15 Waiver of Jury Trial. EACH OF THE COMPANY, THE GUARANTORS AND THE TRUSTEE
HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO
TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR
THE TRANSACTION CONTEMPLATED THEREBY.

     Section 16.16 Consent to Jurisdiction.

     (a) Each of the Company and the Guarantors hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of any competent New York State court or
federal court of the United States sitting in the State and City of New York,
County of New York and Borough of Manhattan, and any appellate court from any thereof, in any
action or proceeding arising out of or relating to this Indenture or the Notes, or for recognition
or enforcement of any judgment, and each of the parties hereto hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or proceeding may be heard and
determined in such state court sitting in the State and City of New York, County of New York and
Borough of Manhattan or, to the extent permitted by law, in such federal court sitting in the State
and City of New York, County of New York and Borough of Manhattan.

     (b) Each of the Company and the Guarantors hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it may now or
hereafter have to the laying of venue of any suit, action proceeding arising out of or relating to
this Indenture or the Notes in any such New York State or federal court. Each of the parties

88

 

hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such court.

     Section 16.17 Force Majeure. In no event shall the Trustee be responsible or liable for
any failure or delay in the performance of its obligations hereunder arising out of or caused by,
directly or indirectly, forces beyond its control, including, without limitation, strikes, work
stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural
catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications
or computer (software or hardware) services; it being understood that the Trustee shall use
reasonable efforts which are consistent with accepted practices in the banking industry to resume
performance as soon as practicable under the circumstances.

Ladies and Gentlemen:

          Endeavour International Corporation, a Nevada corporation (the “Company”), proposes to issue
and sell to the several parties named in Schedule I hereto (the “Initial Purchasers”), $120,000,000
principal amount of its 5.5% Convertible Senior Notes due 2016 (the “Firm Securities”). The Company
also proposes to grant to the Initial Purchasers an option to purchase up to $15,000,000 additional
principal amount of such 5.5% Convertible Senior Notes due 2016 to cover over-allotments, if any
(the “Option Securities” and, together with the Firm Securities, the “Securities”). The Securities
are to be issued under an indenture (the “Indenture”), to be dated as of the Closing Date, between
the Company, the guarantors listed in Schedule IV hereto (the “Guarantors”), and Wells Fargo Bank,
National Association, as trustee (the “Trustee”), and will be guaranteed on an unsecured senior
basis by each of the Guarantors (the “Guarantees”). The Securities will be convertible into shares
(the “Underlying Securities”) of common stock of the Company, par value $0.001 per share (the
“Common Stock”). The Company and the Guarantors are hereinafter referred to collectively as the
“Endeavour Parties.” Certain terms used herein are defined in Section 22 hereof.

          The sale of the Securities, the Underlying Securities and the Guarantees to the Initial
Purchasers will be made without registration of the Securities, the Underlying Securities and the
Guarantees under the Act in reliance upon exemptions from the registration requirements of the Act.

          In connection with the sale of the Securities, the Underlying Securities and the Guarantees,
the Company has prepared a preliminary offering memorandum, dated July 18, 2011 (as amended or
supplemented at the date thereof, including any and all exhibits thereto and any information
incorporated by reference therein, the “Preliminary Memorandum”), and a final offering memorandum,
dated July 18, 2011 (as amended or supplemented at the Execution Time, including any and all
exhibits thereto, the “Final Memorandum”). Each of the Preliminary Memorandum and the Final
Memorandum sets forth certain information concerning the Company, the Securities, the Underlying
Securities and the Guarantees. The Company hereby

1

 

confirms that it has authorized the use of the Disclosure Package, the Preliminary Memorandum
and the Final Memorandum, and any amendment or supplement thereto, in connection with the offer and
sale of the Securities, the Underlying Securities and the Guarantees by the Initial Purchasers.
Unless stated to the contrary, any references herein to the terms “amend,” “amendment” or
“supplement” with respect to the Disclosure Package, the Preliminary Memorandum and the Final
Memorandum shall be deemed to refer to and include any information filed under the Exchange Act
subsequent to the Execution Time that is incorporated by reference therein and all references
herein to the terms “Disclosure Package” and “Final Memorandum” shall be deemed to mean and include
all information filed under the Exchange Act prior to the Execution Time and incorporated by
reference in the Disclosure Package or the Final Memorandum (“Incorporated Documents”).

          1. Representations and Warranties. Each of the Endeavour Parties, jointly and
severally, represents and warrants to, and agrees with, each Initial Purchaser as set forth below
in this Section 1.

          (a) The Preliminary Memorandum, at the date thereof, did not contain any untrue statement of a
material fact or omit to state any material fact necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading. As of its date and
on the Closing Date and any settlement date, the Final Memorandum did not and will not (and any
amendment or supplement thereto, at the date thereof and at the Closing Date and on any settlement
date, will not) contain any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements therein, in the light of the circumstances under which
they were made, not misleading; provided, however, that the Company makes no
representation or warranty as to the information contained in or omitted from the Preliminary
Memorandum or the Final Memorandum, or any amendment or supplement thereto, in reliance upon and in
conformity with information furnished in writing to the Company by or on behalf of the Initial
Purchasers specifically for inclusion therein, it being understood and agreed that the only such
information furnished by or on behalf of any Initial Purchaser consists of the information
described as such in Section 8(b) hereof.

          (b) (i) The Disclosure Package, as of the Execution Time and (ii) any road show, when taken
together as a whole with the Disclosure Package, does not contain any untrue statement of a
material fact or omit to state any material fact necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading. The preceding
sentence does not apply to statements in or omissions from the foregoing based upon and in
conformity with written information furnished to the Company by any Initial Purchaser specifically
for use therein, it being understood and agreed that the only such information furnished by or on
behalf of any Initial Purchaser consists of the information described as such in Section 8(b)
hereof.

          (c) None of the Company, its Affiliates or any person acting on its or their behalf (other
than the Initial Purchasers) has, directly or indirectly, made offers or sales of any security, or
solicited offers to buy, any security under circumstances that would require the registration of
the Securities, the Underlying Securities and the Guarantees under the Act.

2

 

          (d) None of the Company, its Affiliates or any person acting on its or their behalf (other
than the Initial Purchasers) has engaged in any form of general solicitation or general advertising
(within the meaning of Regulation D) in connection with any offer or sale of the Securities, the
Underlying Securities and the Guarantees.

          (e) The Securities and the Guarantees satisfy the eligibility requirements of Rule 144A(d)(3)
under the Act.

          (f) Subject to compliance by the Initial Purchasers with their representations and warranties
contained herein, no registration under the Act of the Securities, the Underlying Securities and
the Guarantees or qualification of the Indenture under the Trust Indenture Act is required for the
offer and sale of the Securities, the Underlying Securities and the Guarantees to or by the Initial
Purchasers in the manner contemplated herein, in the Disclosure Package and the Final Memorandum.

          (g) Neither the Company nor any of its Subsidiaries is, and after giving effect to the
offering and sale of the Securities and the Guarantees and the application of the proceeds thereof
as described in the Disclosure Package and the Final Memorandum will be, an “investment company” as
defined in the Investment Company Act.

          (h) The Company has not paid or agreed to pay to any person any compensation for soliciting
another to purchase any securities of the Company (except as contemplated in this Agreement).

          (i) Each of the Company and its Subsidiaries has been duly formed and is validly existing in
good standing under the laws of the jurisdiction in which it is chartered or organized with full
power and authority to own or lease, as the case may be, and to operate its properties and conduct
its business as described in the Disclosure Package and the Final Memorandum, and is duly qualified
to do business and is in good standing under the laws of each jurisdiction which requires such
qualification, except for such jurisdictions where the failure to so qualify or to be in good
standing would not, individually or in the aggregate, result in a Material Adverse Effect (as
defined below).

          (j) All the outstanding shares of capital stock (or corresponding equity interest) of the
Company and each Subsidiary have been duly and validly authorized and issued and are fully paid and
nonassessable, and, except as otherwise set forth in the Disclosure Package and the Final
Memorandum and except as arise under or pursuant to the credit agreement dated August 16, 2010
between the Company, Endeavour Energy UK Limited, Cyan Partners, LP and various lenders listed
therein (the “Credit Agreement”), all outstanding shares of capital stock (or corresponding equity
interest) of the Subsidiaries are owned by the Company either directly or through wholly owned
Subsidiaries free and clear of any perfected security interest or any other security interests,
claims, liens or encumbrances; and, except as set forth in the Disclosure Package and the Final
Memorandum, no options, warrants or other rights to purchase, agreements or other obligations to
issue, or rights to convert any obligations into or exchange any securities for, shares of capital
stock of or ownership interests in the Company are outstanding.

3

 

          (k) Each of the Securities, the Underlying Securities and the Guarantees and the Indenture
conforms in all material respects to the descriptions thereof contained in each of the Disclosure
Package and the Final Memorandum. The descriptions of statutes, legal, governmental and regulatory
proceedings and contracts and other documents insofar as such descriptions summarize legal matters,
agreements, documents or proceedings discussed therein, are accurate and fair descriptions of such
legal matters, agreements, documents or proceedings in all material respects.

          (l) The Company’s authorized equity capitalization is as set forth in the Disclosure Package
and the Final Memorandum; the outstanding shares of Common Stock have been duly authorized and
validly issued and are fully paid and nonassessable; the Underlying Securities reserved for
issuance upon conversion of the Securities have been duly authorized and, when issued in accordance
with the terms of the Securities, will be validly issued, fully paid and nonassessable and the
issuance of the Underlying Securities will not be subject to any preemptive or similar rights.

          (m) This Agreement has been duly authorized, executed and delivered by each of the Endeavour
Parties.

          (n) The Indenture has been duly authorized by the Company and each of the Guarantors and,
assuming due authorization, execution and delivery thereof by the Trustee, when executed and
delivered by the Company and the Guarantors, will constitute a legal, valid and binding instrument
enforceable against the Company and each of the Guarantors in accordance with its terms (subject,
as to the enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium
or other laws affecting creditors’ rights generally from time to time in effect and to general
principles of equity).

          (o) The Securities have been duly authorized by the Company, and, when executed and
authenticated in accordance with the provisions of the Indenture and delivered to and paid for by
the Initial Purchasers, will have been duly executed and delivered by the Company and will
constitute the legal, valid and binding obligations of the Company, enforceable against the Company
in accordance with their terms (subject, as to the enforcement of remedies, to applicable
bankruptcy, reorganization, insolvency, moratorium or other laws affecting creditors’ rights
generally from time to time in effect and to general principles of equity), and will be entitled to
the benefits of the Indenture and will be convertible into the Underlying Securities in accordance
with their terms; and the Guarantees have been duly authorized by each of the Guarantors and, when
the Securities have been duly executed, authenticated, issued and delivered in accordance with the
provisions of the Indenture and paid for by the Initial Purchasers, will constitute the legal,
valid and binding obligations of each of the Guarantors, enforceable against each of the Guarantors
in accordance with their terms (subject, as to the enforcement of remedies, to applicable
bankruptcy, reorganization, insolvency, moratorium or other laws affecting creditors’ rights
generally from time to time in effect and to general principles of equity), and will be entitled to
the benefits of the Indenture.

          (p) No consent, approval, authorization, filing with or order of any court or governmental

4

 

or in the Indenture, except such as may be required under the blue sky laws of any
jurisdiction in which the Securities are offered and sold.

          (q) None of the execution and delivery of this Agreement or the Indenture, the issuance and
sale of the Securities, the Underlying Securities and the Guarantees, the consummation of any other
of the transactions contemplated in this Agreement or the Indenture, the application of the
proceeds therefrom as set forth in the Disclosure Package or the fulfillment of the terms hereof or
thereof will conflict with, require any other consent under, result in a breach or violation of, or
imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of
its Subsidiaries pursuant to (i) the organizational documents of the Company or any of its
Subsidiaries, (ii) the terms of any indenture, contract, lease, mortgage, deed of trust, note
agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to
which the Company or any of its Subsidiaries is a party or bound or to which its or their property
is subject, or (iii) any statute, law, rule, regulation, judgment, order or decree applicable to
the Company or any of its Subsidiaries of any court, regulatory body, administrative agency,
governmental body, arbitrator or other authority having jurisdiction over the Company or any of its
Subsidiaries or any of its or their properties, except, with respect to clauses (ii) and (iii)
only, for such defaults or violations as would not, individually or in the aggregate, result in a
Material Adverse Effect and except for such as have been obtained.

          (r) The consolidated historical financial statements and schedules of the Company and its
consolidated Subsidiaries included in the Disclosure Package and the Final Memorandum present
fairly the financial condition, results of operations and cash flows of the Company as of the dates
and for the periods indicated, comply as to form in all material respects with the applicable
accounting requirements of Regulation S-X and have been prepared in conformity with generally
accepted accounting principles applied on a consistent basis throughout the periods involved
(except as otherwise noted therein). The selected financial data set forth under the captions

Data” in the Preliminary Memorandum and the Final Memorandum fairly present, on the basis stated in
the Preliminary Memorandum and the Final Memorandum, the information included therein. The other
financial, reserve and statistical data contained in the Preliminary Memorandum and the Final
Memorandum (and any amendment or supplement thereto) are accurately and fairly presented and
prepared on a basis consistent with the financial statements and books and records of the Company
and its Subsidiaries. There are no financial statements (historical or pro forma) that would be
required to be included or incorporated by reference in a prospectus filed with the Commission
under the Act or the Exchange Act in connection with the Company’s pending acquisition of acreage
and related midstream assets in the Marcellus shale play that are not included or incorporated by
reference as required.

          (s) As of March 31, 2011, the Company had or would have had, on the consolidated historical,
as adjusted, and as further adjusted basis as indicated in the Disclosure Package and the Final
Memorandum, a capitalization as set forth therein under the heading “Capitalization.”

          (t) No action, suit or proceeding by or before any court or governmental agency, authority or
body or any arbitrator involving the Company or any of its Subsidiaries or its or

5

 

their property is pending or, to the best knowledge of the Endeavour Parties, threatened that
could reasonably be expected to (A) have a material adverse effect on the condition (financial or
otherwise), prospects, earnings, business or properties of the Company and its Subsidiaries, taken
as a whole, whether or not arising from transactions in the ordinary course of business or (B)
prevent or materially interfere with the ability of the Endeavour Parties to perform their
respective obligations under this Agreement or the Indenture or consummate any of the transactions
contemplated hereby or thereby (the occurrence of any such effect or any such prevention or
interference or any such result described in the foregoing clauses (A) and (B) being herein
referred to as a “Material Adverse Effect”), except as set forth in or contemplated in the
Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

          (u) Each of the Company and its Subsidiaries owns or leases all such properties as are
necessary to the conduct of its operations as presently conducted or to be conducted on the Closing
Date.

          (v) Neither the Company nor any Subsidiary is in violation or default of (i) any provision of
its organizational documents, (ii) the terms of any indenture, contract, lease, mortgage, deed of
trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or
instrument to which it is a party or bound or to which its property is subject, or (iii) any
statute, law, rule, regulation, judgment, order or decree of any court, regulatory body,
administrative agency, governmental body, arbitrator or other authority having jurisdiction over
the Company or such Subsidiary or any of its properties, as applicable, except, with respect to
clauses (ii) and (iii) only, for such defaults or violations as would not, individually or in the
aggregate, result in a Material Adverse Effect.

          (w) KPMG LLP, who has certified certain financial statements of the Company and its
consolidated Subsidiaries and delivered their report with respect to the audited consolidated
financial statements and schedules included in the Disclosure Package and the Final Memorandum, are
independent public accountants with respect to the Company within the meaning of the Act and the
applicable published rules and regulations thereunder.

          (x) Each of the Company and its Subsidiaries has filed all tax returns that are required to be
filed or has requested extensions thereof (except in any case in which the failure so to file would
not have a Material Adverse Effect and except as set forth in or contemplated in the Disclosure
Package and the Final Memorandum (exclusive of any amendment or supplement thereto)) and has paid
all taxes required to be paid by it and any other assessment, fine or penalty levied against it, to
the extent that any of the foregoing is due and payable, except for any such assessment, fine or
penalty that is currently being contested in good faith or as would not have a Material Adverse
Effect, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum
(exclusive of any amendment or supplement thereto).

          (y) No labor problem or dispute with the employees of the Company or any of its Subsidiaries
exists or to the best knowledge of the Endeavour Parties, is threatened or imminent, and the
Endeavour Parties are not aware of any existing or imminent labor disturbance by the employees of
any of the Company’s or its Subsidiaries’ principal suppliers, contractors or customers, that would
have a Material Adverse Effect, except as set forth in or contemplated in

6

 

the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement
thereto).

          (z) Netherland, Sewell & Associates, Inc., who issued a report with respect to the Company’s
oil and natural gas reserves at December 31, 2010, 2009 and 2008 and who has delivered the letter
referred to in Section 6(h) hereof, was, as of the date of such report, and is, as of the date
hereof, an independent petroleum engineer with respect to the Company.

          (aa) The estimates of net proved oil and gas reserves of the Company as of December 31, 2010,
2009 and 2008 (the “proved reserve estimates”) and the estimates of net proved plus probable oil
and gas reserves of the Company as of December 31, 2010 (the “2P reserve estimates”) contained in
the Disclosure Package and the Final Memorandum were prepared by or audited by Netherland, Sewell &
Associates, Inc.; the proved reserve estimates, the 2P reserve estimates and the estimates of net
probable oil and gas reserves of the Company as of December 31, 2010 included in the Disclosure
Package and the Final Memorandum fairly reflect, in all material respects, the oil and gas reserves
of the Company at the dates indicated therein and are in accordance with the Commission guidelines
applicable thereto applied on a consistent basis throughout the periods involved.

          (bb) The organizational documents of the Company and each of its Subsidiaries have been duly
authorized, executed and delivered by the Company or such Subsidiary, as the case may be, and are
enforceable against the respective parties thereto in accordance with their terms (subject, as to
the enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or
other laws affecting creditors’ rights generally from time to time in effect, to general principles
of equity and public policy, applicable law relating to fiduciary duties and indemnification and
contribution and an implied covenant of good faith and fair dealing).

          (cc) The Company and each of its Subsidiaries are insured by insurers of recognized financial
responsibility against such losses and risks and in such amounts as are customary in the businesses
in which they are engaged; all policies of insurance insuring the Company or any of its
Subsidiaries or their respective businesses, assets, employees, officers and directors are in full
force and effect; the Company and its Subsidiaries are in compliance with the terms of such
policies and instruments in all material respects; and there are no claims by the Company or any
such Subsidiary under any such policy or instrument as to which any insurance company is denying
liability or defending under a reservation of rights clause; neither the Company nor any such
Subsidiary has been refused any insurance coverage sought or applied for; and neither the Company
nor any of its Subsidiaries has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue its business at a cost that would not have a
Material Adverse Effect except as set forth in or contemplated in the Disclosure Package and the
Final Memorandum (exclusive of any amendment or supplement thereto).

          (dd) No Subsidiary is currently prohibited, directly or indirectly, from paying any dividends
to the Company, from making any other distribution on such Subsidiary’s capital stock (or
corresponding equity interest), from repaying to the Company any loans or advances to

7

 

such Subsidiary from the Company or from transferring any of such Subsidiary’s property or
assets to the Company or any other Subsidiary of the Company, except as described in or
contemplated by the Disclosure Package and the Final Memorandum (exclusive of any amendment or
supplement thereto).

          (ee) The Company and its Subsidiaries possess all licenses, certificates, permits and other
authorizations issued by all applicable authorities necessary to conduct their respective
businesses, and neither the Company nor any such Subsidiary has received any notice of proceedings
relating to the revocation or modification of any such license, certificate, authorization or
permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or
finding, would have a Material Adverse Effect, except as set forth in or contemplated in the
Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

          (ff) The Company and each of its Subsidiaries maintain a system of internal accounting
controls sufficient to provide reasonable assurance that (i) transactions are executed in
accordance with management’s general or specific authorizations; (ii) transactions are recorded as
necessary to permit preparation of financial statements in conformity with generally accepted
accounting principles and to maintain asset accountability; (iii) access to assets is permitted
only in accordance with management’s general or specific authorization; and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable intervals and
appropriate action is taken with respect to any differences. The Company and the Subsidiaries’
internal controls over financial reporting are effective and the Endeavour Parties are not aware of
any material weakness in their internal control over financial reporting.

          (gg) The Company and its Subsidiaries maintain “disclosure controls and procedures” (as such
term is defined in Rule 13a-15(e) under the Exchange Act); such disclosure controls and procedures
are effective.

          (hh) None of the Endeavour Parties has taken, directly or indirectly, any action designed to
or that would constitute or that could reasonably be expected to cause or result in, under the
Exchange Act or otherwise, stabilization or manipulation of the price of any security of the
Company to facilitate the sale or resale of the Securities and the Guarantees.

          (ii) Since March 31, 2010, none of the Company or any of its Subsidiaries has sustained any
material loss or interference with its business from fire, explosion, flood or other calamity,
whether or not covered by insurance, or from any labor dispute or court or governmental action,
investigation, order or decree, otherwise than as set forth or contemplated in the Disclosure
Package and the Final Memorandum. Except as disclosed in the Disclosure Package and the Final
Memorandum (or any amendment or supplement thereto), subsequent to the respective dates as of which
such information is given in the Disclosure Package and the Final Memorandum (or any amendment or
supplement thereto), (i) none of the Company or any of its Subsidiaries has incurred any liability
or obligation, indirect, direct or contingent, or entered into any transactions, not in the
ordinary course of business, that, individually or in the aggregate, is material to the Company and
its Subsidiaries, taken as a whole, (ii) there has not been any material change in the
capitalization or material increase in the short-term debt or long-term debt of the Company or any
of its Subsidiaries and (iii) there has not been any material

8

 

adverse change, or any development involving, individually or in the aggregate, a prospective
material adverse change in or affecting the general affairs, condition (financial or other),
business, prospects, assets or results of operations of the Company and its Subsidiaries.

          (jj) The Company and its Subsidiaries are (i) in compliance with any and all applicable
foreign, federal, state and local laws and regulations relating to the protection of human health
and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants
(“Environmental Laws”), (ii) have received and are in compliance with all permits, licenses or
other approvals required of them under applicable Environmental Laws to conduct their respective
businesses and (iii) have not received notice of any actual or potential liability under any
Environmental Law, except where such non-compliance with Environmental Laws, failure to receive
required permits, licenses or other approvals, or liability would not, individually or in the
aggregate, have a Material Adverse Effect, except as set forth in or contemplated in the Disclosure
Package and the Final Memorandum (exclusive of any amendment or supplement thereto). Except as set
forth in the Disclosure Package and the Final Memorandum, neither the Company nor any of the
Subsidiaries has been named as a “potentially responsible party” under the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980, as amended.

          (kk) In the ordinary course of its business, the Company periodically reviews the effect of
Environmental Laws on the business, operations and properties of the Company and its Subsidiaries,
in the course of which it identifies and evaluates associated costs and liabilities (including,
without limitation, any capital or operating expenditures required for clean-up, closure of
properties or compliance with Environmental Laws, or any permit, license or approval, any related
constraints on operating activities and any potential liabilities to third parties). On the basis
of such review, the Company has reasonably concluded that such associated costs and liabilities
would not, singly or in the aggregate, have a Material Adverse Effect, except as set forth in or
contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or
supplement thereto).

          (ll) None of the following events has occurred or exists: (i) a failure to fulfill the
obligations, if any, under the minimum funding standards of Section 302 of the United States
Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and the regulations and
published interpretations thereunder with respect to a Plan, determined without regard to any
waiver of such obligations or extension of any amortization period; (ii) an audit or investigation
by the Internal Revenue Service, the U.S. Department of Labor, the Pension Benefit Guaranty
Corporation or any other federal or state governmental agency or any foreign regulatory agency with
respect to the employment or compensation of employees by any of the Company or any of its
Subsidiaries that could have a Material Adverse Effect; (iii) any breach of any contractual
obligation, or any violation of law or applicable qualification standards, with respect to the
employment or compensation of employees by the Company or any of its Subsidiaries that could have a
Material Adverse Effect. None of the following events has occurred or is reasonably likely to
occur: (i) a material increase in the aggregate amount of contributions required to be made to all
Plans in the current fiscal year of the Company and its Subsidiaries compared to the amount of such
contributions made in the most recently completed fiscal year of the Company and its Subsidiaries;
(ii) a material increase in the “accumulated post-retirement benefit obligations” (within the
meaning of Statement of Financial Accounting Standards 106) of the

9

 

Company and its Subsidiaries compared to the amount of such obligations in the most recently
completed fiscal year of the Company and its Subsidiaries; (iii) any event or condition giving rise
to a liability under Title IV of ERISA that could have a Material Adverse Effect; or (iv) the
filing of a claim by one or more employees or former employees of the Company or any of its
Subsidiaries related to their employment that could have a Material Adverse Effect. For purposes
of this paragraph, the term “Plan” means a plan (within the meaning of Section 3(3) of ERISA)
subject to Title IV of ERISA with respect to which the Company or any of its Subsidiaries may have
any liability.

          (mm) There is and has been no failure on the part of the Company and any of the Company’s
directors or officers, in their capacities as such, to comply with any provision of the
Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the
“Sarbanes-Oxley Act”), including Section 402 relating to loans and Sections 302 and 906 relating to
certifications.

          (nn) Neither the Company nor any of its Subsidiaries nor, to the knowledge of the Endeavour
Parties, any director, officer, agent, employee or Affiliate of the Company or any of its
Subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a
violation by such persons of the Foreign Corrupt Practices Act of 1977, as amended, and the rules
and regulations thereunder (the “FCPA”), including, without limitation, making use of the mails or
any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment,
promise to pay or authorization of the payment of any money, or other property, gift, promise to
give, or authorization of the giving of anything of value to any “foreign official” (as such term
is defined in the FCPA) or any foreign political party or official thereof or any candidate for
foreign political office, in contravention of the FCPA; and the Company, its Subsidiaries and, to
the knowledge of the Endeavour Parties, its Affiliates, have conducted their businesses in
compliance with the FCPA and have instituted and maintain policies and procedures designed to
ensure, and which are reasonably expected to continue to ensure, continued compliance therewith.

          (oo) The operations of the Company and its Subsidiaries are and have been conducted at all
times in compliance with applicable financial recordkeeping and reporting requirements and the
money laundering statutes and the rules and regulations thereunder and any related or similar
rules, regulations or guidelines, issued, administered or enforced by any governmental agency
(collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any
court or governmental agency, authority or body or any arbitrator involving the Company or any of
its Subsidiaries with respect to the Money Laundering Laws is pending or, to the knowledge of the
Endeavour Parties, threatened.

          (pp) Neither the Company nor any of its Subsidiaries nor, to the knowledge of the Endeavour
Parties, any director, officer, agent, employee or Affiliate of the Company or any of its
Subsidiaries is currently subject to any sanctions administered by the Office of Foreign Assets
Control of the U.S. Treasury Department (“OFAC”); and the Company will not directly or indirectly
use the proceeds of the offering of the Securities and the Guarantees, or lend, contribute or
otherwise make available such proceeds to any Subsidiary, joint venture partner or other person or
entity, for the purpose of financing the activities of any person currently subject to any U.S.
sanctions administered by OFAC.

10

 

          (qq) The Subsidiaries, after excluding Endeavour Operating Corporation, a Delaware corporation
(“Endeavour Operating”), and Endeavour Energy UK Limited, a company organized under the laws of the
United Kingdom (“Endeavour Energy UK”), did not, individually or in aggregate, account for more
than 10% of the consolidated net income of the Company and its Subsidiaries for the year ended
December 31, 2010.

          Any certificate signed by any officer of the Company or any Guarantor and delivered to the
Initial Purchasers or counsel for the Initial Purchasers in connection with the offering of the
Securities and the Guarantees shall be deemed a representation and warranty by the Company or such
Guarantor, as the case may be, as to matters covered thereby, to each Initial Purchaser.

          2. Purchase and Sale.

          (a) Subject to the terms and conditions and in reliance upon the representations and
warranties herein set forth, the Company agrees to sell to each Initial Purchaser, and each Initial
Purchaser agrees, severally and not jointly, to purchase from the Company, at a purchase price of
96.75% of the principal amount thereof, plus accrued interest, if any, from July 22, 2011 to the
Closing Date, the principal amount of Firm Securities set forth opposite such Initial Purchaser’s
name in Schedule I hereto.

          (b) Subject to the terms and conditions and in reliance upon the representations and
warranties herein set forth, the Company hereby grants an option to the several Initial Purchasers
to purchase, severally and not jointly, the Option Securities at the same purchase price as Initial
Purchasers shall pay for the Firm Securities, plus accrued interest, if any, from July 22, 2011 to
the settlement date for the Option Securities. The option may be exercised only to cover
over-allotments in the sale of the Firm Securities by the Initial Purchasers. The option may be
exercised in whole or in part at any time or from time to time on or before the 30th day after the
date of the Final Memorandum upon written or telephonic notice by the Initial Purchasers to the
Company setting forth the principal amount of Option Securities as to which the several Initial
Purchasers are exercising the option and the settlement date. Delivery of the Option Securities,
and payment therefor, shall be made as provided in Section 3 hereof. The principal amount of
Option Securities to be purchased by each Initial Purchaser shall be the same percentage of the
total principal amount of Option Securities to be purchased by the several Initial Purchasers as
such Initial Purchaser is purchasing of the Firm Securities, subject to such adjustments as you in
your absolute discretion shall make to eliminate any fractional Securities.

          3. Delivery and Payment. Delivery of and payment for the Firm Securities, the
Guarantees and the Option Securities (if the option provided for in Section 2(b) hereof shall have
been exercised on or before the first Business Day immediately preceeding the Closing Date) shall
be made at 10:00 a.m., New York City time, on July 22, 2011, or at such time on such later date not
more than three Business Days after the foregoing date as the Initial Purchasers shall designate,
which date and time may be postponed by agreement between the Initial Purchasers and the Company or
as provided in Section 9 hereof (such date and time of delivery and payment for the Securities and
the Guarantees being herein called the “Closing Date”). Delivery of the Securities and the
Guarantees shall be made to the respective accounts of the Initial Purchasers against payment by
the Initial Purchasers of the purchase price thereof to or upon the order of the

11

 

Company by wire transfer payable in same-day funds to the account specified by the Company.
Delivery of the Firm Securities, the Guarantees and, if applicable, the Option Securities shall be
made by delivery of one or more certificates in global form representing such Securities at such
location as Citigroup shall reasonably designate at least one Business Day in advance of the
Closing Date. The global certificates representing the Firm Securities and, if applicable, the
Option Securities shall be registered in such names and in such denominations as Citigroup may
request not less than two Business Days in advance of the Closing Date. The Company agrees to have
such Securities available for inspection, checking and packaging by the Initial Purchasers or
counsel for the Initial Purchasers at One Shell Plaza, 910 Louisiana, Houston, Texas 77002, not
later than 5:00 PM on the Business Day prior to the Closing Date.

          (a) If the option provided for in Section 2(b) hereof is exercised after the first Business
Day immediately preceding the Closing Date, the Company will deliver the Option Securities (at the
expense of the Company) to the Initial Purchasers on the date specified by the Initial Purchasers
(which shall be within three Business Days after exercise of said option) for the respective
accounts of the Initial Purchasers, against payment by the Initial Purchasers of the purchase price
thereof to or upon the order of the Company by wire transfer payable in same-day funds to the
account specified by the Company. If settlement for the Option Securities occurs after the Closing
Date, the Company will deliver to the Initial Purchasers on the settlement date for the Option
Securities, and the obligation of the Initial Purchasers to purchase the Option Securities shall be
conditioned upon receipt of, supplemental opinions, certificates and letters confirming as of such
date the opinions, certificates and letters delivered on the Closing Date pursuant to Section 6
hereof.

          4. Offering by Initial Purchasers. (a) Each Initial Purchaser acknowledges that the
Securities, the Underlying Securities and the Guarantees have not been and will not be registered
under the Act and may not be offered or sold within the United States or to, or for the account or
benefit of, U.S. persons, except pursuant to an exemption from, or in a transaction not subject to,
the registration requirements of the Act.

          (b) Each Initial Purchaser, severally and not jointly, represents and warrants to and agrees
with the Company that:

     (i) it has not offered or sold, and will not offer or sell, any Securities or
Guarantees within the United States or to, or for the account or benefit of, U.S.
persons as part of their distribution at any time, except to those it reasonably
believes to be “qualified institutional buyers” (as defined in Rule 144A under the
Act).

     (ii) neither it nor any person acting on its behalf has made or will make
offers or sales of the Securities in the United States by means of any form of
general solicitation or general advertising (within the meaning of Regulation D) in
the United States;

     (iii) in connection with each sale pursuant to Section 4(b)(i)(A), it has taken
or will take reasonable steps to ensure that the purchaser of such Securities is
aware that such sale may be made in reliance on Rule 144A; and

12

 

     (iv) it is an “accredited investor” (as defined in Rule 501(a) of Regulation
D).

          5. Agreements. Each of the Endeavour Parties, jointly and severally, agrees with each
Initial Purchaser that:

          (a) The Company will furnish to each Initial Purchaser and to counsel for the Initial
Purchasers, without charge, prior to the completion of the distribution of the Securities by the
Initial Purchasers (as determined by the Initial Purchasers), as many copies of the Preliminary
Memorandum and the Final Memorandum and any amendments and supplements thereto as they may
reasonably request.

          (b) The Company will prepare a final term sheet, containing solely a description of final
terms of the Securities and the Guarantees and the offering thereof, in the form approved by you
and attached as Schedule II hereto.

          (c) The Company will not amend or supplement the Disclosure Package or the Final Memorandum,
other than by filing documents under the Exchange Act that are incorporated by reference therein,
without the prior written consent of the Initial Purchasers; provided, however, that prior to the
completion of the distribution of the Securities by the Initial Purchasers (as determined by the
Initial Purchasers), the Company will not file any document under the Exchange Act that is
incorporated by reference in the Disclosure Package or the Final Memorandum unless, prior to such
proposed filing, the Company has furnished the Initial Purchasers with a copy of such document for
their review and the Initial Purchasers have not reasonably objected to the filing of such
document. The Company will promptly advise the Initial Purchasers when any document filed under
the Exchange Act that is incorporated by reference in the Disclosure Package or the Final
Memorandum shall have been filed with the Commission.

          (d) If at any time prior to the completion of the distribution of the Securities by the
Initial Purchasers (as determined by the Initial Purchasers), any event occurs as a result of which
the Disclosure Package or the Final Memorandum, as then amended or supplemented, would include any
untrue statement of a material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were made or the
circumstances then prevailing, not misleading, or if it should be necessary to amend or supplement
the Disclosure Package or the Final Memorandum to comply with applicable law, the Company will
promptly (i) notify the Initial Purchasers of any such event; (ii) subject to the requirements of
Section 5(c), prepare an amendment or supplement that will correct such statement or omission or
effect such compliance; and (iii) supply any supplemented or amended Disclosure Package or Final
Memorandum to the several Initial Purchasers and counsel for the Initial Purchasers without charge
in such quantities as they may reasonably request.

          (e) Without the prior written consent of the Initial Purchasers, the Company has not given and
will not give to any prospective purchaser of the Securities any written information concerning the
offering of the Securities other than materials contained in the Disclosure Package, the Final
Memorandum or any other offering materials prepared by the Initial Purchasers.

13

 

          (f) The Company will arrange, if necessary, for the qualification of the Securities and the
Guarantees for sale by the Initial Purchasers under the laws of such jurisdictions as the Initial
Purchasers may designate and will maintain such qualifications in effect so long as required for
the sale of the Securities and the Guarantees; provided that in no event shall the Company be
obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take
any action that would subject it to service of process in suits, other than those arising out of
the offering or sale of the Securities and the Guarantees, in any jurisdiction where it is not now
so subject. The Company will promptly advise the Initial Purchasers of the receipt by the Company
of any notification with respect to the suspension of the qualification of the Securities and the
Guarantees for sale in any jurisdiction or the initiation or threatening of any proceeding for such
purpose.

          (g) During the period from the Closing Date until one year after the Closing Date, or any
settlement date, if applicable, without the prior written consent of the Initial Purchasers, the
Company will not, and will not permit any of its Affiliates to, resell any of the Securities or
Underlying Securities which constitute “restricted securities” under Rule 144 that have been
reacquired by any of them.

          (h) None of the Company, its Affiliates, or any person acting on its or their behalf will,
directly or indirectly, make offers or sales of any security, or solicit offers to buy any
security, under circumstances that would require the registration of the Securities, the Underlying
Securities or the Guarantees under the Act.

          (i) Any information provided by the Company, its Affiliates or any person acting on its or
their behalf to publishers of publicly available databases about the terms of the Securities shall
include a statement that the Securities have not been registered under the Act and are subject to
restrictions under Rule 144A under the Act;

          (j) None of the Company, its Affiliates, or any person acting on its or their behalf will
engage in any form of general solicitation or general advertising (within the meaning of Regulation
D) in connection with any offer or sale of the Securities in the United States.

          (k) For so long as any of the Securities are outstanding and are “restricted securities”
within the meaning of Rule 144(a)(3) under the Act, the Company, during any period in which it is
not subject to and in compliance with Section 13 or 15(d) of the Exchange Act or it is not exempt
from such reporting requirements pursuant to and in compliance with Rule 12g3-2(b) under the
Exchange Act, will provide to each holder of such restricted securities and to each prospective
purchaser (as designated by such holder) of such restricted securities, upon the request of such
holder or prospective purchaser, any information required to be provided by Rule 144A(d)(4) under
the Act. This covenant is intended to be for the benefit of the holders, and the prospective
purchasers designated by such holders, from time to time of such restricted securities.

          (l) The Company will cooperate with the Initial Purchasers and use commercially reasonable
efforts to permit the Securities to be eligible for clearance and settlement through The Depository
Trust Company.

14

 

          (m) The Company will reserve and keep available at all times, free of pre-emptive rights, the
full number of Underlying Securities.

          (n) Each of the Securities and the Underlying Securities will bear, to the extent applicable,
the legend contained in “Notice to Investors” in the Preliminary Memorandum and the Final
Memorandum for the time period and upon the other terms stated therein.

          (o) The Company will not for a period of 60 days following the Execution Time, directly or
indirectly, without the prior written consent of the Initial Purchasers offer, sell, contract to
sell, pledge, otherwise dispose of, enter into any transaction which is designed to, or might
reasonably be expected to, result in the disposition (whether by actual disposition or effective
economic disposition due to cash settlement or otherwise) by the Company or any Affiliate of the
Company or any Affiliate of the Company or any person in privity with the Company or any Affiliate
of the Company of, file (or participate in the filing of) a registration statement with the
Commission in respect of, or establish or increase a put equivalent position or liquidate or
decrease a call equivalent position within the meaning of Section 16 of the Exchange Act in respect
of, any shares of capital stock of the Company or any securities convertible into, or exercisable
or exchangeable for, shares of capital stock of the Company (other than the Securities), or
publicly announce an intention to effect any such transaction; provided, however,
that the Company may (i) issue and sell Common Stock or securities convertible into or exchangeable
for Common Stock pursuant to any employee stock option plan, stock ownership plan or dividend
reinvestment plan of the Company described in the Disclosure Package and the Final Memorandum and
in effect at the Execution Time, (ii) issue Common Stock issuable upon the conversion of securities
or the exercise of warrants outstanding at the Execution Time and described in the Disclosure
Package and the Final Memorandum and (iii) file any registration statement with the Commission on
Form S-8 relating to the offering of securities pursuant to any employee stock option plan, stock
ownership plan or dividend reinvestment plan of the Company described in the Disclosure Package and
the Final Memorandum and in effect at the Execution Time.

          (p) None of the Endeavour Parties will take, directly or indirectly, any action designed to,
or that would constitute or that could reasonably be expected to, cause or result in, under the
Exchange Act or otherwise, stabilization or manipulation of the price of any security of the
Company to facilitate the sale or resale of the Securities.

          (q) Between the date hereof and the Closing Date, the Company will not do or authorize any act
or thing that would result in an adjustment of the conversion price of the Securities.

          (r) The Endeavour Parties will apply the net proceeds from the sale of the Securities and the
Guarantees in the manner described in each of the Disclosure Package and the Final Memorandum under
the heading “Use of Proceeds.”

          (s) The Company agrees to pay the costs and expenses relating to the following matters: (i)
the preparation of the Indenture and the issuance of the Securities, the Guarantees and the Common
Stock upon conversion of the Securities and the fees of the Trustee (including related fees and
expenses of any counsel to the Trustee); (ii) the preparation, printing or

15

 

reproduction of the Preliminary Memorandum and the Final Memorandum and each amendment or
supplement to either of them; (iii) the printing (or reproduction) and delivery (including postage,

in each case, be reasonably requested for use in connection with the offering and sale of the
Securities and the Guarantees; (iv) the preparation, printing, authentication, issuance and
delivery of certificates for the Securities and the Guarantees; (v) any stamp or transfer taxes in

          (u) The Company will comply with any requirements of the UK Listing Rules or the London Stock
Exchange applicable to the Securities or the Underlying Securities.

          6. Conditions to the Obligations of the Initial Purchasers. The obligations of the
Initial Purchasers to purchase the Firm Securities, the Guarantees and the Option Securities, as
the case may be, shall be subject to the accuracy of the representations and warranties of the
Endeavour Parties contained herein at the Execution Time and the Closing Date (except to the extent

case of clauses (A) and (B) above, for any such conflict, breach, violation,

obligations of each of the Guarantors, enforceable against each of the Guarantors in
accordance with their terms (subject to the Enforceability Exceptions), and will be
entitled to the benefits of the Indenture;

     In addition, such counsel shall state that they have participated in
conferences with officers and other representatives of the Company, the independent
public accountants of the Company, the independent reserve engineers, the Initial
Purchasers and counsel for the Initial Purchasers, at which the contents of the

although such counsel has not independently verified, is not passing upon, and is
not assuming any responsibility for the accuracy, completeness or fairness of the
statements contained in, the Disclosure Package and the Final Memorandum (except as
specifically described in the opinions in paragraph (iii) and (iv) of the foregoing
opinion), based on the foregoing no facts have come to the attention of such counsel
that lead such counsel to believe that:

	 	1.	 	the Disclosure Package, as of the Execution
Time, included an untrue statement of a material fact or omitted to
state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made,
not misleading, or
	 
	 	2.	 	the Final Memorandum, as of its date and on the
Closing Date, included or includes an untrue statement of a material
fact or omitted or omits to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under
which they were made, not misleading;

it being understood that such counsel expresses no statement or belief with respect
to (i) the financial statements and related schedules, including the notes thereto
and independent registered public accountants’ reports thereon, included or
incorporated by reference in the Disclosure Package or the Final Memorandum, (ii)
any other financial data or accounting data, information pertaining to oil and

the Disclosure Package or the Final Memorandum, or (iii) representations and
warranties and other statements of fact included in the exhibits to the Incorporated
Documents.

19

 

     Such counsel need not express any opinion as to the enforceability of any
provisions relating to: (a) any failure to comply with requirements concerning
notices, relating to delay or omission to enforce rights or remedies or purporting
to waive or affect rights, claims, defenses or other benefits to the extent that any
of the same cannot be waived or so affected under applicable law; (b) indemnities or
exculpation from liability to the extent prohibited by federal or state laws and the
public policies underlying those laws or that might require indemnification for, or
exculpation from liability on account of, gross negligence, willful misconduct,
unlawful acts, fraud or illegality of an indemnified or exculpated party; (c)
requirements that all amendments, waivers and terminations be in writing or the
disregard of any course of dealing between the parties; (d) default interest,
liquidated damages and other penalty provisions; (e) the avoidance of the effect of
any fraudulent transfer, fraudulent conveyance laws or similar provisions of
applicable law by limiting the amount of the Guarantor’s obligation under the
Indenture or the Guarantees; or (f) applicable bankruptcy, insolvency, moratorium,
fraudulent transfer or similar laws affecting the enforcement of creditors’ rights
generally and equitable principals and implied covenants of good faith and fair
dealing relating to enforceability (clauses (a) through (f) collectively, the
“Enforceability Exceptions”);

In rendering such opinion, such counsel may rely (A) as to matters involving the
application of laws of any jurisdiction other than the States of New York or Texas,
the laws of the United Kingdom, the Delaware General Corporation Law the federal
laws of the United States, to the extent they deem proper and specified in such
opinion, upon the opinion of other counsel of good standing whom they believe to be
reliable and who are satisfactory to counsel for the Initial Purchasers and (B) as
to matters of fact, to the extent they deem proper, on certificates of responsible
officers of the Endeavour Parties and public officials. References to the Final
Memorandum in this paragraph (b) shall also include any supplements thereto at the
Closing Date. In the case of opinion points (ii) and (vii)(C), in each case solely
with respect to Endeavour Energy UK, such counsel may limit its opinions to the laws
of the United Kingdom. With respect to each other opinion, such counsel may limit
its opinions to the laws of the States of New York and Texas, Delaware General
Corporation Law and the federal laws of the United States, to the extent
specifically referred to herein.

          (b) The Initial Purchasers shall have received the opinion of Woodburn and Wedge, opining as
to the law of Nevada, addressed to the Initial Purchasers and dated the Closing Date, to the effect
that:

     (i) the Company’s authorized equity capitalization is as set forth in the
Disclosure Package and the Final Memorandum; the capital stock of the Company
conforms to the description thereof incorporated by reference in the Disclosure
Package and the Final Memorandum; the Underlying Securities reserved for issuance
upon conversion of the Securities have been duly authorized and reserved and, when
issued upon conversion of the Securities in accordance with the terms of the
Securities, will be validly issued, fully paid and non-assessable

20

 

and the issuance of the Underlying Securities will not be subject to any
preemptive or other rights to subscribe for the Securities or the Underlying
Securities and, to such counsel’s knowledge, except as set forth in the Disclosure
Package and the Final Memorandum, no options, warrants or other rights to purchase,
agreements or other obligations to issue, or rights to convert any obligations into
or exchange any securities for, shares of capital stock of or ownership interests in
the Company are outstanding;

     (ii) the Company has been duly incorporated and is validly existing as a

distribution of the Securities and the Guarantees by the Initial Purchasers in the
manner contemplated in this Agreement, the Disclosure Package and the Final
Memorandum (as to which Woodburn and Wedge shall not offer any opinion) and such
other approvals as have been obtained; and

     (vi) none of the execution and delivery of the Indenture or this Agreement, the
issuance and sale of the Securities and the Guarantees, nor the consummation of any
other of the transactions contemplated herein or in the Indenture, nor the
fulfillment of the terms hereof or thereof will conflict with, result in a breach or
violation of, or imposition of any lien, charge or encumbrance upon any property or
assets of the Company pursuant to, (i) the organizational documents of the Company
or (ii) any Nevada statute, law, rule, regulation, or to the knowledge of Woodburn
and Wedge, any judgment, order or decree applicable to the Company of any Nevada
court, regulatory body, administrative agency, governmental body, arbitrator or
other authority having jurisdiction over the Company or any of its properties.

In rendering such opinion, such counsel may rely (A) as to matters involving the
application of laws of any jurisdiction other than the State of Nevada, to the
extent they deem proper and specified in such opinion, upon the opinion of other
counsel of good standing whom they believe to be reliable and who are satisfactory
to counsel for the Initial Purchasers and (B) as to matters of fact, to the extent
they deem proper, on certificates of responsible officers of the Company and public
officials. References to the Disclosure Package and Final

21

 

Memorandum in this paragraph (b) shall also include any amendments or supplements
thereto at the Closing Date. Additionally, the opinions expressed by such counsel
may be limited to the laws of the State of Nevada.

          (c) The Initial Purchasers shall have received from Baker Botts L.L.P., counsel for the
Initial Purchasers, such opinion or opinions, dated the Closing Date and addressed to the Initial
Purchasers, with respect to the issuance and sale of the Securities and the Guarantees, the
Indenture, the Disclosure Package, the Final Memorandum (as amended or supplemented at the Closing
Date) and other related matters as the Initial Purchasers may reasonably require, and the Company
shall have furnished to such counsel such documents as they reasonably request for the purpose of
enabling them to pass upon such matters.

          (d) The Company shall have furnished to the Initial Purchasers certificates of each of the
Endeavour Parties, signed by (x) the Chairman of the Board or the President and (y) the principal
financial or accounting officer of each of the Endeavour Parties, dated the Closing Date, to the
effect that the signers of such certificate have carefully examined the Disclosure Package and the
Final Memorandum and any supplements or amendments thereto, as well as each electronic road show
used in connection with the offering of the Securities, and this Agreement and that:

     (i) the representations and warranties of the Endeavour Parties in this
Agreement are true and correct on and as of the Closing Date with the same effect as
if made on the Closing Date (except to the extent such representations and
warranties expressly relate to a specific earlier date (in which case such
representations and warranties shall be true and correct as of such specified
earlier date)), and the Endeavour Parties have complied with all the agreements and
satisfied all the conditions on their part to be performed or satisfied hereunder at
or prior to the Closing Date; and

     (ii) since the date of the most recent financial statements included in the
Disclosure Package and the Final Memorandum (exclusive of any amendment or
supplement thereto), there has been no Material Adverse Effect, except as set forth
in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of
any amendment or supplement thereto);

          (e) At the Execution Time and at the Closing Date, the Company shall have requested and caused
KPMG LLP to furnish to the Initial Purchasers letters, dated respectively as of the Execution Time
and as of the Closing Date, in form and substance reasonably satisfactory to the Initial Purchasers
and confirming that they are independent accountants within the meaning of the Exchange Act and the
applicable published rules and regulations thereunder and stating in effect that:

     (i) in their opinion, the audited financial statements and financial statement
schedules included in the Preliminary Memorandum and the Final Memorandum and
reported on by them comply as to form with the applicable accounting requirements of
Regulation S-X;

22

 

     (ii) on the basis of a reading of the latest unaudited financial statements
made available by the Company and its Subsidiaries; their limited review in
accordance with the standards established under Statement on Auditing Standards No.
100 of the unaudited interim financial information included or incorporated by
reference in the Preliminary Memorandum or Final Memorandum for the three month
period ended March 31, 2011 and as at March 31, 2011; carrying out certain specified
procedures (but not an examination in accordance with generally accepted auditing
standards) which would not necessarily reveal matters of significance with respect
to the comments set forth in such letter; a reading of the minutes of the meetings
of the shareholders, directors and committees of the Company and the Subsidiaries;
and inquiries of certain officials of the Company who have responsibility for
financial and accounting matters of the Company and its Subsidiaries as to
transactions and events subsequent to December 31, 2010, nothing came to their
attention which caused them to believe that:

	 	(A)	 	any unaudited financial
statements included in the Preliminary Memorandum or the Final
Memorandum do not comply as to form with the applicable
accounting requirements of Regulation S-X or are not in
conformity with generally accepted accounting principles applied
on a basis substantially consistent with that of the audited
financial statements included in the Preliminary Memorandum and
the Final Memorandum;
	 
	 	(B)	 	with respect to the period
subsequent to March 31, 2011, there were any changes, at a
specified date not more than five days prior to the date of the
letter, in the long-term debt of the Company and its
Subsidiaries or Common Stock of the Company or changes in the
stockholders’ equity or net assets and liabilities of the
Company as compared with the amounts shown on the March 31, 2011
consolidated balance sheet included or incorporated by reference
in the Preliminary Memorandum and the Final Memorandum, or for
the period from April 1, 2011 to such specified date there were
any decreases, as compared with the corresponding period in the
preceding year in consolidated revenues or net income (in total
or per share amounts) of the Company and its Subsidiaries,
except in all instances for changes or decreases set forth in
such letter, in which case the letter shall be accompanied by an
explanation by the Company as to the significance thereof unless
said explanation is not deemed necessary by the Initial
Purchasers;

     (iii) they have performed certain other specified procedures as a result of
which they determined that certain information of an accounting, financial or

23

 

statistical nature (which is limited to accounting, financial or statistical
information derived from the general accounting records of the Company and its
Subsidiaries) set forth or incorporated by reference in the Preliminary Memorandum
and the Final Memorandum agrees with the accounting records of the Company and its
Subsidiaries, excluding any questions of legal interpretation.

          (f) Subsequent to the Execution Time or, if earlier, the dates as of which information is
given in the Disclosure Package (exclusive of any amendment or supplement thereto) and the Final
Memorandum (exclusive of any amendment or supplement thereto), there shall not have been (i) any
change or decrease specified in the letter or letters referred to in paragraph (e) of this Section
6; or (ii) any Material Adverse Effect, the effect of which, in any case referred to in clause (i)
or (ii) above, is, in the sole judgment of the Initial Purchasers, so material and adverse as to
make it impractical or inadvisable to proceed with the offering or delivery of the Securities as
contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or
supplement thereto).

          (g)
Subsequent to the Execution Time, there shall not have been any decrease in the rating of any
of the Company’s debt securities by any “nationally recognized statistical rating organization” (as
defined for purposes of Rule 3(a)(2) under the Exchange Act) or any notice given of any intended or
potential decrease in any such rating or of a possible change in any such rating that does not
indicate the direction of the possible change.

          (h) Netherland, Sewell & Associates, Inc. shall have delivered to you at the Closing Date, a
letter in form and substance reasonably satisfactory to you, stating, as of the date hereof and as
of the Closing Date the conclusions and findings of such firm with respect to the oil and gas
reserves of the Company and its Subsidiaries.

          (i) The Endeavour Parties shall have executed and delivered the Indenture, in form and
substance reasonably satisfactory to the Initial Purchasers, and the Initial Purchasers shall have
received executed copies thereof.

          (j) The Securities shall be eligible for clearance and settlement through DTC.

          (k) Prior to the Execution Time, the Company shall have furnished to the Initial Purchasers a
letter substantially in the form of Exhibit A hereto from each officer and director of the Company
addressed to the Initial Purchasers.

          (l) Prior to the Closing Date, the Company shall have furnished to the Initial Purchasers such
further information, certificates and documents as the Initial Purchasers may reasonably request.

          If any of the conditions specified in this Section 6 shall not have been fulfilled when and as
provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere
in this Agreement shall not be reasonably satisfactory in form and substance to the Initial
Purchasers and counsel for the Initial Purchasers, this Agreement and all obligations of the
Initial Purchasers hereunder may be canceled at, or at any time prior to, the Closing Date by the
Initial Purchasers. Notice of such cancellation shall be given to the Company in writing or by
telephone or facsimile confirmed in writing.

24

 

          The documents required to be delivered by this Section 6 will be delivered at the office of
counsel for the Initial Purchasers, at One Shell Plaza, 910 Louisiana, Houston, Texas 77002 at 9:00
a.m., Houston time, on the Closing Date.

          7. Reimbursement of Expenses. If the sale of the Securities and the Guarantees
provided for herein is not consummated because any condition to the obligations of the Initial
Purchasers set forth in Section 6 hereof is not satisfied, because of any termination pursuant to
Section 10 hereof or because of any refusal, inability or failure on the part of the Company to
perform any agreement herein or comply with any provision hereof other than by reason of a default
by any of the Initial Purchasers, the Company will reimburse the Initial Purchasers severally on
demand for all expenses (including reasonable fees and disbursements of counsel) that shall have
been incurred by them in connection with the proposed purchase and sale of the Securities and the
Guarantees.

          8. Indemnification and Contribution. (a) Each of the Endeavour Parties, jointly and
severally, agrees to indemnify and hold harmless each Initial Purchaser, the directors, officers,
employees, Affiliates and agents of each Initial Purchaser and each person who controls any Initial
Purchaser within the meaning of either the Act or the Exchange Act against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of them may become subject
under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at
common law or otherwise, insofar as such losses, claims, damages or liabilities or actions in
respect thereof arise out of or are based upon any untrue statement or alleged untrue statement of
a material fact contained in the Preliminary Memorandum, the Disclosure Package, the Final
Memorandum, any Issuer Written Information or any other written information used by or on behalf of
the Endeavour Parties in connection with the offer or sale of the Securities and the Guarantees
(including, without limitation, any road show used in connection with the offer or sale of the
Securities and the Guarantees), or in any amendment or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein, in the light of the circumstances under which
they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred,
for any legal or other expenses reasonably incurred by it in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however, that the Endeavour
Parties will not be liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any such untrue statement or alleged untrue statement or
omission or alleged omission made in the Preliminary Memorandum, the Disclosure Package, the Final
Memorandum or such other written information, or in any amendment thereof or supplement thereto, in
reliance upon and in conformity with written information furnished to the Company by or on behalf
of any Initial Purchaser specifically for inclusion therein. This indemnity agreement will be in
addition to any liability that the Endeavour Parties may otherwise have.

          (b) Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless
the Endeavour Parties, each of their directors, each of their officers, and each person who
controls the Endeavour Parties within the meaning of either the Act or the Exchange Act, to the
same extent as the foregoing indemnity to each Initial Purchaser, but only with reference to
written information relating to such Initial Purchaser furnished to the Company by or on behalf of
such Initial Purchaser specifically for inclusion in the Preliminary Memorandum, the

25

 

Disclosure Package or the Final Memorandum (or in any amendment or supplement thereto). This
indemnity agreement will be in addition to any liability that any Initial Purchaser may otherwise
have. The Company acknowledges that (i) the statements set forth in the last paragraph of the
cover page regarding delivery of the Securities and (ii) under the heading “Plan of Distribution,”
(A) the sentences related to concessions, and (B) the sentences related to stabilization, syndicate
covering transactions and penalty bids in the Preliminary Memorandum and the Final Memorandum
constitute the only information furnished in writing by or on behalf of the Initial Purchasers for
inclusion in the Preliminary Memorandum, the Disclosure Package or the Final Memorandum or in any
amendment or supplement thereto.

          (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the
commencement of any action, such indemnified party will, if a claim in respect thereof is to be
made against the indemnifying party under this Section 8, notify the indemnifying party in writing
of the commencement thereof; but the failure so to notify the indemnifying party (i) will not
relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the indemnifying party
of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party
from any obligations to any indemnified party other than the indemnification obligation provided in
paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party
in any action for which indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel, retained by the
indemnified party or parties except as set forth below); provided, however, that
such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying
party’s election to appoint counsel to represent the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel (including local counsel), and
the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel
if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would
present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or
targets of, any such action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal defenses available to it
and/or other indemnified parties that are different from or additional to those available to the
indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to
the indemnified party to represent the indemnified party within a reasonable time after notice of
the institution of such action; or (iv) the indemnifying party shall authorize the indemnified
party in writing to employ separate counsel at the expense of the indemnifying party. An
indemnifying party will not, without the prior written consent of the indemnified parties, settle
or compromise or consent to the entry of any judgment with respect to any pending or threatened
claim, action, suit or proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential parties to such claim or
action) unless such settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising out of such claim, action, suit or proceeding.

          (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party for any reason, the Endeavour
Parties and the Initial Purchasers severally agree to contribute to the aggregate losses, claims,
damages and liabilities (including legal or other expenses reasonably incurred in

26

 

connection with investigating or defending any loss, claim, damage, liability or action)
(collectively “Losses”) to which any of the Endeavour Parties and one or more of the Initial
Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits
received by the Endeavour Parties on the one hand and by the Initial Purchasers on the other from
the offering of the Securities; provided, however, that in no case shall any Initial Purchaser be
responsible for any amount in excess of the purchase discount or commission applicable to the
Securities purchased by such Initial Purchaser hereunder. If the allocation provided by the
immediately preceding sentence is unavailable for any reason, the Endeavour Parties and the Initial
Purchasers severally shall contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Endeavour Parties on the one hand and the
Initial Purchasers on the other in connection with the statements or omissions that resulted in
such Losses, as well as any other relevant equitable considerations. Benefits received by the
Endeavour Parties shall be deemed to be equal to the total net proceeds from the offering (before
deducting expenses) received by the Company, and benefits received by the Initial Purchasers shall
be deemed to be equal to the total purchase discounts and commissions. Relative fault shall be
determined by reference to, among other things, whether any untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact relates to information
provided by the Company on the one hand or the Initial Purchasers on the other, the intent of the
parties and their relative knowledge, access to information and opportunity to correct or prevent
such untrue statement or omission. The Endeavour Parties and the Initial Purchasers agree that it
would not be just and equitable if contribution were determined by pro rata allocation or any other
method of allocation that does not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes
of this Section 8, each person who controls an Initial Purchaser within the meaning of either the
Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Initial
Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who
controls any of the Endeavour Parties within the meaning of either the Act or the Exchange Act and
each officer and director of the Endeavour Parties shall have the same rights to contribution as
the Endeavour Parties, subject in each case to the applicable terms and conditions of this
paragraph (d).

          9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail
to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser
hereunder and such failure to purchase shall constitute a default in the performance of its or
their obligations under this Agreement, the remaining Initial Purchasers shall be obligated
severally to take up and pay for (in the respective proportions which the principal amount of
Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal
amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the
Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to
purchase; provided, however, that in the event that the aggregate principal amount of Securities
which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall
exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the
remaining Initial Purchasers shall have the right to purchase all, but shall not be under any
obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not
purchase all the Securities, this Agreement will terminate without liability to any nondefaulting
Initial

27

 

Purchaser or any of the Endeavour Parties. In the event of a default by any Initial Purchaser
as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding
five Business Days, as the Initial Purchasers shall determine in order that the required changes in
the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained
in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the
Endeavour Parties or any nondefaulting Initial Purchaser for damages occasioned by its default
hereunder.

          10. Termination. This Agreement shall be subject to termination in the absolute
discretion of the Initial Purchasers, by notice given to the Company prior to delivery of and
payment for the Securities, if at any time prior to such time (i) trading in the Company’s Common
Stock shall have been suspended by the Commission or the New York Stock Exchange or trading in
securities generally on the New York Stock Exchange shall have been suspended or limited or minimum
prices shall have been established on such exchange, (ii) a banking moratorium shall have been
declared either by U.S. federal or New York State authorities; or (iii) there shall have occurred
any outbreak or escalation of hostilities, declaration by the United States of a national emergency
or war or other calamity or crisis the effect of which on financial markets is such as to make it,
in the sole judgment of the Initial Purchasers, impractical or inadvisable to proceed with the
offering or delivery of the Securities as contemplated in the Disclosure Package and the Final
Memorandum (exclusive of any amendment or supplement thereto).

          11. Representations and Indemnities to Survive. The respective agreements,
representations, warranties, indemnities and other statements of the Endeavour Parties or their
officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain
in full force and effect, regardless of any investigation made by or on behalf of the Initial
Purchasers or the Endeavour Parties or any of the indemnified persons referred to in Section 8
hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7
and 8 hereof shall survive the termination or cancellation of this Agreement.

          12. Notices. All communications hereunder will be in writing and effective only on
receipt, and, if sent to the Initial Purchasers, will be mailed, delivered or telefaxed to the
Citigroup General Counsel (fax no.: (212) 816-7912) and confirmed to Citigroup at 388 Greenwich
Street, New York, New York 10013, Attention: General Counsel; or, if sent to any of the Endeavour
Parties, will be mailed, delivered or telefaxed to J. Michael Kirksey (fax no.: (813) 307-8794) and
confirmed to it at 1001 Fannin Street, Suite 1600, Houston, Texas 77002, Attention: Chief Financial
Officer.

          13. Successors. This Agreement will inure to the benefit of and be binding upon the
parties hereto and their respective successors and the indemnified persons referred to in Section 8
hereof and their respective successors, and no other person will have any right or obligation
hereunder.

          14. Integration. This Agreement supersedes all prior agreements and understandings
(whether written or oral) between the Endeavour Parties and the Initial Purchasers, or any of them,
with respect to the subject matter hereof.

28

 

          15. Applicable Law. This Agreement will be governed by and construed in accordance
with the laws of the State of New York applicable to contracts made and to be performed within the
State of New York.

          16. Jurisdiction. Each of the Endeavour Parties hereby agrees that any suit, action
or proceeding against the Endeavour Parties brought by any Initial Purchaser, the directors,
officers, employees and agents of any Initial Purchaser, or by any person who controls any Initial
Purchaser, arising out of or based upon this Agreement or the transactions contemplated hereby may
be instituted in any State or U.S. federal court in The City of New York and County of New York,
and waives any objection which it may now or hereafter have to the laying of venue of any such
proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any suit,
action or proceeding.

          17. Waiver of Jury Trial. Each of the Endeavour Parties hereby irrevocably waives, to
the fullest extent permitted by applicable law, any and all right to trial by jury in any legal
proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

          18. No Fiduciary Duty. Each of the Endeavour Parties hereby acknowledges that (a) the
purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial
transaction between the Endeavour Parties, on the one hand, and the Initial Purchasers and any
Affiliate through which it may be acting, on the other, (b) the Initial Purchasers are acting as
principal and not as an agent or fiduciary of the Endeavour Parties and (c) the Company’s
engagement of the Initial Purchasers in connection with the offering and the process leading up to
the offering is as independent contractors and not in any other capacity. Furthermore, each of the

Revised Use of Proceeds Disclosure

$130.0 million if the initial purchasers’ over-allotment option is exercised in full), after
deducting the initial purchasers’ discounts and commissions and estimated offering expenses and
assuming no original issue or other discount. We intend to use substantially all of the net
proceeds of this offering to fund the consideration for our pending Marcellus Acquisition. The
remainder will be used for general corporate purposes, including funding a portion of our 2011
capital program. If we are unable to consummate the Marcellus Acquisition, we intend to use the net
proceeds of this offering for general corporate purposes, including the potential repayment of
certain of our outstanding indebtedness.

     We estimate that our portion of the total expenses of this offering will be approximately
