(b) Purposes.

     This Plan is intended to foster and promote the long-term financial success of the Company and
its subsidiaries and to increase stockholder value by: (a) encouraging the commitment of selected
employees, (b) motivating superior performance of certain employees by means of long-term
performance related incentives, (c) encouraging and providing certain employees with a program for
obtaining ownership interests in the Company which link and align their personal interests to those
of the Company’s stockholders, (d) attracting and retaining certain employees by providing
competitive incentive compensation opportunities, and (e) enabling certain employees to share in
the long-term growth and success of the Company.

     This Plan provides for payment of various forms of incentive compensation and it is not
intended to be a plan that is subject to ERISA. The Plan shall be interpreted, construed and
administered consistent with its status as a plan that is not subject to ERISA.

II. Administration

     The Plan shall be administered by the Committee. The Committee shall have sole authority to
select the Participants from among those individuals eligible hereunder and

3

 

to establish the number of shares of Restricted Stock and/or Incentive Stock which may be
granted and shares which may be issued under each Stock Option; provided, however, that,
notwithstanding any provision in the Plan to the contrary, the maximum number of shares that may be
subject to Stock Options granted under the Plan to an individual Optionee during any calendar year
may not exceed 200,000 shares (subject to adjustment in the same manner as provided in Section VIII
hereof with respect to Shares subject to Stock Options then outstanding) and the maximum number of
shares of Restricted Stock and/or Incentive Stock that may be granted to an individual Grantee
under the Plan during any calendar year may not exceed 100,000 shares (subject to adjustment in the
same manner as provided in Section VIII hereof with respect to Shares subject to Stock Options then
outstanding). The limitation set forth in the preceding sentence shall be applied in a manner which
will permit compensation generated under the Plan to constitute “performance-based” compensation
for purposes of Section 162(m) of the Code, including, without limitation, counting against such
maximum number of shares, to the extent required under Section 162(m) of the Code and applicable
interpretive authority thereunder, any shares subject to Stock Options that are canceled or
repriced. In selecting Participants from among individuals eligible hereunder and in establishing
the number of shares of Restricted Stock and/or Incentive Stock that may be issued to each Grantee
and the number of shares that may be issued under each Stock Option, the Committee may take into
account the nature of the services rendered by such individuals, their present and potential
contributions to the Company’s success and such other factors as the Committee in its discretion
shall deem relevant. The Committee is authorized to interpret the Plan and may from time to time
adopt such rules and regulations, consistent with the provisions of the Plan, as it may deem
advisable to carry out the Plan. All decisions made by the Committee in selecting the Participants,
in establishing the number of shares of Restricted Stock and/or Incentive Stock which may be issued
to each Grantee and the number of shares which may be issued under each Stock Option and in
construing the provisions of the Plan shall be final.

III. Types of Grants Under the Plan

(a) Types of Grants.

     Pursuant to this Plan, the Company may grant shares of Restricted Stock, shares of Incentive
Stock, and Stock Options. Stock Options granted under the Plan may be either Incentive Stock
Options or Non Statutory Stock Options.

(b) Grants of Restricted Stock.

     Subject to the terms and provisions of the Plan, the Committee, at any time and from time to
time, may grant Restricted Stock to any eligible person in such amounts and with such restrictions
as the Committee shall determine, any of which restrictions may differ with respect to any Grantee.
A certificate or certificates representing the number of shares of Restricted Stock granted shall
be registered in the name of the Grantee. Until the expiration of the Restriction Period or the
lapse of restrictions in the manner provided in the Grantee’s Restricted Stock Agreement, the
certificate or certificates shall be held in

4

 

escrow by the Company for the account of the Grantee. The Grantee shall have beneficial
ownership of the shares of Restricted Stock, including the right to receive dividends and the right
to vote the shares of Restricted Stock. Upon the lapse of all restrictions (as set forth in the
Grantee’s Restricted Stock Agreement) on any or all of the Restricted Stock granted to the Grantee,
the certificate or certificates representing the shares of Restricted Stock for which the
restrictions have lapsed shall be delivered to the Grantee.

     Each Restricted Stock Award shall be evidenced by a Restricted Stock Agreement which shall
contain the Restriction Period, the number of shares of Restricted Stock and such other terms and
conditions as may be approved by the Committee, including other restrictions as the Committee may
determine. The Committee may impose such conditions or restrictions on any Restricted Stock as it
may deem advisable, in its sole discretion.

(c) Grant of Incentive Stock.

     Subject to the terms and provisions of the Plan, the Committee, at any time and from time to
time, may grant Incentive Stock to any eligible person in such amounts as the Committee shall
determine. Each Incentive Stock Award shall be evidenced by an Incentive Stock Agreement which
shall contain the number of Shares granted and such other terms and conditions as may be approved
by the Committee.

(d) Grant of Stock Options.

     Subject to the terms and conditions of the Plan, the Committee is authorized to grant Stock
Options to any eligible person.

     Each Stock Option shall be evidenced by an Option Agreement, which shall contain such terms
and conditions as may be approved by the Committee. The terms and conditions of the respective
Option Agreements need not be identical for each Optionee. The Option Price upon exercise of any
Stock Option shall be payable to the Company in full either: (i) in cash or its equivalent, or (ii)
subject to prior approval by the Committee in its discretion, by tendering previously acquired
Shares having an aggregate Fair Market Value at the time of exercise equal to the total Option
Price (provided that the Shares which are tendered must have been held by the Optionee for at least
six (6) months prior to their tender to satisfy the option price), or (iii) subject to prior
approval by the Committee, in its discretion, by withholding Shares which otherwise would be
acquired on exercise having an aggregate Fair Market Value at the time of exercise equal to the
total Option Price, or (iv) subject to prior approval by the Committee in its discretion, by a
combination of (i), (ii), and (iii) above. Any payment in Shares shall be effected by the surrender
of such Shares to the Company in good form for transfer and shall be valued at their Fair Market
Value on the date when the Stock Option is exercised. Unless otherwise permitted by the Committee,
in its discretion, the Optionee shall not surrender, or attest to the ownership of, Shares in
payment of the Option Price if such action would cause the Company to recognize compensation (or
additional

5

 

compensation expense) with respect to the Stock Option for financial reporting purposes
expense.

     The Committee, in its discretion, also may allow the Option Price to be paid with such other
consideration as shall constitute lawful consideration for the issuance of Shares (including,
without limitation, effecting a “cashless exercise” with a broker of the Stock Option), subject to
applicable securities law restrictions and tax withholdings, or by any other means which the
Committee determines to be consistent with the Plan’s purpose and applicable law. A “cashless
exercise” of a Stock Option is a procedure by which a broker provides the funds to the Optionee to
effect a Stock Option exercise, to the extent consented to by the Committee, in its discretion. At
the direction of the Optionee, the broker will either (i) sell all of the Shares received when the
Stock Option is exercised and pay the Optionee the proceeds of the sale (minus the Option Price,
withholding taxes and any fees due to the broker) or (ii) sell enough of the Shares received upon
exercise of the Stock Option to cover the Option Price, withholding taxes and any fees due the
broker and deliver to the Optionee (either directly or through the Company) a stock certificate for
the remaining Shares.

     In no event will the Committee allow the Option Price to be paid with a form of consideration,
including a loan or a “cashless exercise,” if such form of consideration would violate the
Sarbanes-Oxley Act of 2002 as determined by the Committee, in its discretion.

     As soon as practicable after receipt of a written notification of exercise and full payment,
the Company shall deliver, or cause to be delivered, to or on behalf of the Optionee, in the name
of the Optionee or other appropriate recipient, Share certificates for the number of Shares
purchased under the Stock Option. Such delivery shall be effected for all purposes when the Company
or a stock transfer agent of the Company shall have deposited such certificates in the United
States mail, addressed to Grantee or other appropriate recipient.

IV. Eligibility of Participants, Term and Transferability

     Restricted Stock, Incentive Stock and Stock Options may be granted only to individuals who are
employees (including officers and directors who are also employees) of the Company or any parent or
subsidiary corporation (as defined in Section 424 (e) and (f) of the Code) of the Company at the
time the Restricted Stock, Incentive Stock or Stock Option is granted. Restricted Stock, Incentive
Stock and Stock Options may be granted to the same individual on more than one occasion. No
Incentive Stock Option shall be granted to an eligible person who owns or who would own immediately
before the grant of such Incentive Stock Option more than 10% of the total combined voting power of
all classes of stock of the Company or its parent or subsidiary corporation, unless (i) at the time
such Stock Option is granted the option price is 110% of the Fair Market Value of the Shares
granted on the date of the grant and (ii) such Stock Option by its terms is not exercisable after
the expiration of five (5) years from the date of grant. The term of each Stock Option granted to
other eligible persons shall be not more than

6

 

ten (10) years from the date of the grant. To the extent that the aggregate Fair Market Value
(determined at the time the respective Incentive Stock Option is granted) of Shares with respect to
which Incentive Stock Options are exercisable for the first time by an individual during any
calendar year under all incentive stock option plans of the Company and its parent and subsidiary
corporations exceeds $100,000, such excess Incentive Stock Options shall be treated as
Non-Statutory Stock Options. The Committee shall determine, in accordance with applicable
provisions of the Code, treasury regulations and other administrative pronouncements, which of an
Optionee’s Stock Options will not constitute Incentive Stock Options because of such limitation and
shall notify the Optionee of such determination as soon as practicable after such determination.

     Restricted Stock and Stock Options granted under the Plan shall not be transferable or
assignable other than: (a) by will or the laws of descent and distribution or (b) pursuant to a
qualified domestic relations order (as defined by Section 414(p) of the Code); provided, however,
if an Incentive Stock Option is transferred pursuant to a qualified domestic relations order (as
defined by Section 414(p) of the Code), the Option shall cease to qualify as an Incentive Stock
option as of the date of such transfer; provided, further, however, only with respect to
Non-Statutory Stock Options, the Committee may, in its discretion, authorize all or a portion of
the Non-Statutory Stock Options to be granted on terms which permit transfer by the Optionee to (i)
the members of the Optionee’s Immediate Family, (ii) a trust or trusts for the exclusive benefit of
such Immediate Family, or (iii) a partnership in which such members of such Immediate Family are
the only partners, provided that (A) there may be no consideration for any such transfer, (B) the
Incentive Stock Agreement pursuant to which such Non-Statutory Stock Options are granted must be
approved by the Committee, and must expressly provide for transferability in a manner consistent
with this Section and (C) subsequent transfers of transferred Stock Options shall be prohibited
except in accordance with clauses (A) and (B) above of this sentence. Following any permitted
transfer, any Non-Statutory Stock Option shall continue to be subject to the same terms and
conditions as were applicable immediately prior to transfer, provided that the term “Optionee”
shall be deemed to refer to the transferee. The Non-Statutory Stock Option shall be exercisable by
the transferee only to the extent, and for the periods, specified in the Option Agreement.

     Except as may otherwise be permitted under the Code, in the event of a permitted transfer of a
Non-Statutory Stock Option hereunder, the original Optionee shall remain subject to withholding
taxes upon exercise. In addition, the Company shall have no obligation to provide any notices to a
transferee including, for example, the termination of a Stock Option following the original
Optionee’s termination of employment.

     No transfer by will, trust or by the laws of descent and distribution shall be effective to
bind the Company unless the Committee has been furnished with a copy of the deceased Grantee’s or
Optionee’s enforceable will, trust or such other evidence as the Committee deems necessary to
establish the validity of the transfer. Any attempted transfer in violation of this provision shall
be void and ineffective. All determinations under this Section shall be made by the Committee in
its discretion.

7

 

     In the event the employment of a person by the Company (or a subsidiary) shall be terminated
at a time when such person holds an Incentive Stock Option, such person (or in the event employment
is terminated due to death or disability of such person, his or her personal representative) may
exercise his or her Incentive Stock Option (to the extent such person was entitled to exercise such
Incentive Stock Option as of the date of termination) but only within such period of time ending on
the earlier of (i) the date that is three months following the termination of such person’s
employment (or such shorter or longer period specified in the Option Agreement) or (ii) the
expiration of the term of the Incentive Stock Option as set forth in the Option Agreement;
provided, however, if termination of employment is due to the death or disability (as defined in
section 22(e)(3) of the Code) of such person the three month period set forth in (i) above shall be
extended to 12 months.

V. Shares Subject to Plan

     The aggregate number of shares of Restricted Stock, shares of Incentive Stock and Shares which
may be issued under Stock Options granted under the Plan shall not exceed 4,250,000. In addition,
the aggregate number of shares of Restricted Stock and Incentive Stock combined which may be issued
under the Plan shall not exceed 2,125,000. Such shares may consist of authorized but unissued
Shares, treasury shares of Common Stock, or previously issued Shares reacquired by the Company. Any
of such Shares which remain unissued and which are not subject to outstanding Stock Options at the
termination of the Plan shall cease to be subject to the Plan, but, until termination of the Plan,
the Company shall at all times make available a sufficient number of Shares to meet the
requirements of the Plan. Should any Stock Option hereunder expire or terminate prior to its
exercise in full, the Shares theretofore subject to such Stock Option may again be subject to a
Stock Option granted under the Plan to the extent permitted under Rule 16b-3. Upon the forfeiture
of any Restricted Stock, the forfeited shares of Restricted Stock shall thereafter be available for
award under the Plan. The aggregate number of Shares which may be issued under the Plan shall be
subject to adjustment in the same manner as provided in Section VIII hereof with respect to Shares
subject to Stock Options then outstanding. Exercise of a Stock Option in any manner shall result in
a decrease in the number of Shares which may thereafter be available, both for purposes of the Plan
and for grant to any one individual, by the number of Shares as to which the Stock Option is
exercised. Separate stock certificates may be issued by the Company for those Shares acquired
pursuant to the exercise of any Stock Option which does not constitute an Incentive Stock Option.

VI. Option Price

     The Option Price of Shares issued under each Stock Option shall be equal to the Fair Market
Value of Shares subject to the Stock Option on the date the Stock Option is granted; provided,
however, that this limitation shall not apply to Incentive Stock Options for which a greater Option
Price is required pursuant to Paragraph IV hereof.

VII. Term of Plan

8

 

     This Plan became effective as of June 3, 2004, pursuant to approval by the stockholders of the
Company at the 2004 Annual Meeting of Stockholders. Except with respect to Restricted Stock,
Incentive Stock or Stock Options then outstanding, if not sooner terminated under the provisions of
Section IX, the Plan shall terminate upon and no further Restricted Stock, Incentive Stock or Stock
Options shall be granted after June 2, 2014.

VIII. Recapitalization or Reorganization

     (a) The existence of the Plan and the Restricted Stock, Incentive Stock and Stock Options
granted hereunder shall not affect in any way the right or power of the Board or the stockholders
of the Company to make or authorize any adjustment, recapitalization, reorganization or other
change in the Company’s capital structure or its business, any merger or consolidation of the
Company, any issue of debt or equity securities, the dissolution or liquidation of the Company or
any sale, lease, exchange or other disposition of all or any part of its assets or business or any
other corporate act or proceeding.

     (b) The shares with respect to which Stock Options may be granted are shares of Stock as
presently constituted, but if, and whenever, prior to the expiration of a Stock Option theretofore
granted, the Company shall effect a subdivision or consolidation of shares of Stock or the payment
of a stock dividend on Stock without receipt of consideration by the Company, the number of Shares
with respect to which such Stock Option may thereafter be exercised (i) in the event of an increase
in the number of outstanding Shares shall be proportionately increased, and the Option Price per
Share shall be proportionately reduced, and (ii) in the event of a reduction in the number of
outstanding Shares shall be proportionately reduced, and the Option Price per share shall be
proportionately increased.

     (c) If the Company recapitalizes, reclassifies its capital stock, or otherwise changes its
capital structure (a “recapitalization”), the number and class of shares of Stock covered by a
Stock Option theretofore granted shall be adjusted so that such Stock Option shall thereafter cover
the number and class of shares of stock and securities to which the Optionee would have been
entitled pursuant to the terms of the recapitalization if, immediately prior to the
recapitalization, the Optionee had been the holder of record of the number of shares of Stock then
covered by such Stock Option.

     If (i) the Company shall not be the surviving entity in any merger, consolidation or other
reorganization (or survives only as a subsidiary of an entity other than a previously wholly-owned
subsidiary of the Company), (ii) the Company sells, leases or exchanges substantially all of its
assets to any other person or entity (other than a wholly-owned subsidiary of the Company), (iii)
the Company is to be dissolved and liquidated, (iv) any person or entity, including a “group” as
contemplated by Section 13(d)(3) of the Exchange Act acquires or gains ownership or control
(including, without limitation, power to vote) of more than 50% of the outstanding shares of the

9

 

Company’s voting stock (based upon voting power), or (v) as a result of or in connection with
a contested election of directors, the persons who were directors of the Company before such
election shall cease to constitute a majority of the Board (each such event is referred to herein
as a “Corporate Change”), no later than (a) ten (10) days after the approval by the stockholders of
the Company of such merger, consolidation, reorganization, sale, lease or exchange of assets or
dissolution or such election of directors or (b) thirty (30) days after a change of control of the
type described in Clause (iv), the Committee, acting in its sole discretion without the consent or
approval of any Optionee, shall act to effect one or more of the following alternatives, which may
vary among individual Optionees and which may vary among Stock Options held by any individual
Optionee: (1) accelerate the time at which Stock Options then outstanding may be exercised so that
such Stock Options may be exercised in full for a limited period of time on or before a specified
date (before or after such Corporate Change) fixed by the Committee, after which specified date all
unexercised Stock Options and all rights of Optionees thereunder shall terminate, (2) require the
mandatory surrender to the Company by selected Optionees of some or all of the outstanding Stock
Options held by such Optionees (irrespective of whether such Stock Options are then exercisable
under the provisions of the Plan) as of a date, before or after such Corporate Change, specified by
the Committee, in which event the Committee shall thereupon cancel such Stock Options and the
Company shall pay to each Optionee an amount of cash per share to be determined by the Committee,
(3) make such adjustments to Stock Options then outstanding as the Committee deems appropriate to
reflect such Corporate Change (provided, however, that the Committee may determine in its sole
discretion that no adjustment is necessary to Stock Options then outstanding) or (4) provide that
the number and class of shares of Stock covered by a Stock Option theretofore granted shall be
adjusted so that such Stock Option shall thereafter cover the number and class of shares of stock
or other securities or property (including, without limitation, cash) to which the Optionee would
have been entitled pursuant to the terms of the agreement of merger, consolidation or sale of
assets and dissolution if, immediately prior to such merger, consolidation or sale of assets and
dissolution the Optionee had been the holder of record of the number of shares of Stock then
covered by such Stock Option. In addition, no later than (a) ten (10) days after the approval by
the stockholders of the Company of such merger, consolidation, reorganization, sale, lease or
exchange of assets or dissolution or such election of directors or (b) thirty (30) days after a
change of control of the type described in Clause (iv), the Committee, acting in its sole
discretion without the consent or approval of any Grantee, shall act to effect one or more of the
following alternatives, which may vary among individual Grantees and which may vary among
Restricted Stock held by any individual Grantee: (1) remove any and all restrictions to which the
Restricted Stock is subject including removing the Restriction Period, (2) require the mandatory
surrender to the Company by selected Grantees of some or all of the outstanding Restricted Stock
held by such Grantees as of a date, before or after such Corporate Change, specified by the
Committee and the Company shall pay to each Optionee an amount of cash per share to be determined
by the Committee, (3) make such adjustments to the Restricted Stock then outstanding as the
Committee deems appropriate to reflect such Corporate Change (provided, however, that the Committee
may determine in its sole discretion that no adjustment is necessary to the Restricted Stock then

10

 

outstanding) or (4) provide that the number and class of shares of Restricted Stock covered by
a Restricted Stock Agreement theretofore granted shall be adjusted so that such Restricted Stock
shall thereafter cover the number and class of shares of stock or other securities or property
(including, without limitation, cash) to which the Grantee would have been entitled pursuant to the
terms of the agreement of merger, consolidation or sale of assets and dissolution if, immediately
prior to such merger, consolidation or sale of assets and dissolution the Grantee had been the
holder of record of the number of Shares which was not Restricted Stock.

     (d) Except as hereinbefore expressly provided, the issuance by the Company of shares of stock
of any class or securities convertible into shares of stock of any class, for cash, property, labor
or services, upon direct sale, upon the exercise of rights or warrants to subscribe therefor, or
upon conversion of shares or obligations of the Company convertible into such shares or other
securities, and in any case whether or not for fair value, shall not affect, and no adjustment by
reason therefor shall be made with respect to, any Restricted Stock or the number of shares of
Stock subject to Stock Options theretofore granted or the Option Price.

IX. Amendment or Termination of the Plan

     The Board in its discretion may terminate the Plan at any time with respect to any shares for
which Stock Options, Incentive Stock Awards or Restricted Stock Awards have not theretofore been
granted. The Board shall have the right to alter or amend the Plan or any part thereof from time to
time; provided, that no change in any Restricted Stock Agreement, Incentive Stock Agreement or
Stock Option Agreement theretofore granted may be made which would impair the rights of the
Participant without the consent of such Participant (unless such change is required in order to
cause the benefits under the Plan to qualify as performance-based compensation within the meaning
of Section 162(m) of the Code and applicable interpretive authority thereunder); and provided,
further, that (i) the Board may not make any alteration or amendment which would decrease any
authority granted to the Committee hereunder in contravention of Rule 16b-3 and (ii) the Board may
not make any alteration or amendment which would materially increase the benefits accruing to
Participants under the Plan, increase the aggregate number of shares which may be issued pursuant
to the provisions of the Plan, change the class of individuals eligible to receive Restricted
Stock, Incentive Stock or Stock Options under the Plan or extend the term of the Plan, without the
approval of the stockholders of the Company.

X. Securities Laws

     (a) The Company shall not be obligated to issue any Shares pursuant to any Restricted Stock
Agreement, Incentive Stock Agreement or Stock Option granted under the Plan at any time when the
offering of the shares of Restricted Stock, Incentive Stock or shares covered by such Stock Option
have not been registered under the Securities Act of 1933 and such other state and federal laws,
rules or regulations as the Company or the Committee deems applicable and, in the opinion of legal
counsel for the Company, there

11

 

is no exemption from the registration requirements of such laws, rules or regulations
available for the offering and sale of such Shares.

     (b) It is intended that the Plan and any grant of Restricted Stock, Incentive Stock or a Stock
Option made to a person subject to Section 16 of Exchange Act meet all of the requirements of Rule
16b-3. If any provision of the Plan or any such Restricted Stock Agreement, Incentive Stock
Agreement or Stock Option would disqualify the Plan or such Restricted Stock Agreement, Incentive
Stock Agreement or Stock Option under, or would otherwise not comply with, Rule 16b-3, such
provision, Restricted Stock Agreement, Incentive Stock Agreement or Stock Option Agreement shall be
construed or deemed amended to conform to Rule 16b-3.

XI. General

     (a) Nothing contained in this Plan, any Restricted Stock Agreement, any Incentive Stock
Agreement or any Stock Option granted pursuant to this Plan shall confer upon any employee the
right to continue in the employ of the Company or its parent or subsidiary or any other corporation
affiliated with the Company, or interfere in any way with the rights of the Company or its parent
or subsidiaries or any corporation affiliated with the Company to terminate his or her employment.
Except as provided in Article IV (or such shorter or longer period specified in the Option
Agreement), for the entire time from the date of granting an Incentive Stock Option until the date
of exercise, the holder of an Incentive Stock Option must be an employee of the Company (or a
subsidiary of the Company).

     (b) No Optionee shall have any rights as a stockholder of the Company with respect to any
Shares subject to a Stock Option hereunder until such Shares have been issued.

     (c) Nothing contained in this Plan, a Restricted Stock Agreement, an Incentive Stock Agreement
or in any Stock Option Agreement issued hereunder shall impose any liability or responsibility on
the Company, the Board, the Committee or any member or any of the foregoing to pay, or reimburse
any Participant for the payment of any tax arising out of, or on account of the issuance of
Restricted Stock, Incentive Stock or Stock Option or Stock Options hereunder to any Participant, an
Optionee’s exercise of any Stock Option issued under the Plan or a Participant’s sale, transfer or
other disposition of any Restricted Stock, Incentive Stock or Shares acquired pursuant to the
exercise of any Stock Option issued hereunder. Any person receiving Restricted Stock, Incentive
Stock or a Stock Option hereunder shall expressly acknowledge and agree that such participation is

          “144A Global Note” means a global note in substantially the form of Exhibit A hereto bearing
the Global Note Legend and the Private Placement Legend and deposited with or on behalf of, and

          “Attributable Debt” in respect of a sale and leaseback transaction means, at the time of
determination, the present value of the obligation of the lessee for net rental payments during the
remaining term of the lease included in such sale and leaseback transaction including any period

          “Capital Lease Obligation” means, at the time any determination is to be made, the amount of
the liability in respect of a capital lease that would at that time be required to be capitalized
on a balance sheet in accordance with GAAP.

          “Capital Stock” means (1) in the case of a corporation, corporate stock; (2) in the case of an
association or business entity, any and all shares, interests, participations, rights or other
equivalents (however designated) of corporate stock; (3) in the case of a partnership or limited
liability company, partnership or membership interests (whether general or limited); and (4) any

profits and losses of, or distributions of assets of, the issuing person.

          “Cash Equivalents” means (1) United States dollars; (2) securities issued or directly and
fully guaranteed or insured by the United States government or any agency or instrumentality of the
United States government (provided that the full faith and credit of the United States is pledged
in support of those securities) having maturities of not more than six months from the date of
acquisition; (3) certificates of deposit and eurodollar time deposits with maturities of six months
or less from the date of acquisition, bankers’ acceptances with maturities not exceeding six months

such funds of or to which the Trustee or any Affiliate of the Trustee is the sponsor, an advisor, a
trustee or a manager.

          “Change of Control” will be deemed to have occurred at such time when the following has
occurred: (1) a “person” or “group” within the meaning of Section 13(d) of the Exchange Act other
than the Company or its Subsidiaries is or becomes or has become the direct or indirect “beneficial
owner,” as defined in Rule 13d-3 under the Exchange Act, of 50% or more of the Company’s Voting
Stock (including, without limitation, by means of or following a liquidation, share exchange,
tender offer, consolidation, recapitalization, reclassification, merger or direct or indirect
transfer, sale, lease or disposition of all or substantially all of the consolidated assets of the
Company or its Subsidiaries) measured by voting power rather than number of shares; or (2) the
adoption of a plan relating to the liquidation or dissolution of the Company; or (3) the first day

are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the
Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company,
the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a
Note is replaced. The Company may charge for its expenses in replacing a Note.

          (b) Every replacement Note is an additional obligation of the Company and shall be entitled to
all of the benefits of this Indenture equally and proportionately with all other Notes duly issued
hereunder.

Section 2.08. Outstanding Notes.

          (a) The Notes outstanding at any time are all the Notes authenticated by the Trustee except
for those cancelled by it, those delivered to it for cancellation, those reductions in the interest
in a Global Note effected by the Trustee in accordance with the provisions hereof, and those
described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a
Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the
Note.

          (b) If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding and
interest on that Note ceases to accrue unless the Trustee receives proof satisfactory to it that
the replaced Note is held by a bona fide purchaser.

          (c) If the principal amount of any Note is considered paid under Section 4.01 hereof, it
ceases to be outstanding and interest on it ceases to accrue.

          (d) If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof)
holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date,
then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease
to accrue interest.

Section 2.09. Treasury Notes.

          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 person directly or
indirectly controlling or controlled by or under direct or indirect common control with the
Company, shall be considered as though not outstanding, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver or consent, only
Notes that the Trustee knows are so owned shall be so disregarded.

Section 2.10. Temporary Notes.

          Until certificates representing Notes are ready for delivery, the Company may prepare and the
Trustee, upon receipt of an Authentication Order in accordance with Section 2.02 with respect to
such Notes, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form
of Definitive Notes but may have variations that the Company considers appropriate for temporary
Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the
Company shall prepare and, upon receipt of an Authentication Order in accordance with Section 2.02
with respect to such Notes, the Trustee shall authenticate definitive Notes in exchange for
temporary Notes. After the preparation of Definitive Notes, the temporary Notes shall be
exchangeable for Definitive Notes upon surrender of the temporary Notes at the office or agency of
the Company designated for such purpose 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,
upon receipt of an Authentication Order in accordance with Section 2.02 with respect to such Notes,
the Trustee shall authenticate and deliver in exchange therefor a like principal amount of
Definitive Notes of authorized denominations.

          Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

Section 2.11. Cancellation.

     The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and
Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer,

-31-

 

 

exchange or payment. The Trustee, upon direction by the Company and no one else, shall
cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall destroy cancelled Notes (subject to the record retention requirements of the
Exchange Act). Certification of the destruction of all cancelled Notes shall be delivered to the
Company. The Company may not issue new Notes to replace Notes that it has paid or that have been
delivered to the Trustee for cancellation.

Section 2.12. Defaulted Interest.

          If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted
interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted
interest, to the persons who are Holders on a subsequent special record date, in each case at the
rate provided in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Note and the date of the
proposed payment. The Company shall fix or cause to be fixed each such special record date and
payment date; provided, however, that no such special record date shall be less than 5 days prior
to the related payment date for such defaulted interest. At least 10 days before the special
record date, the Company (or, upon the written request of the Company, the Trustee in the name and
at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the
special record date, the related payment date and the amount of such interest to be paid.

Section 2.13. CUSIP Numbers.

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

ARTICLE 3.

REDEMPTION AND PREPAYMENT

Section 3.01. Notices to Trustee.

          If the Company elects to redeem Notes pursuant to the optional redemption provisions of
Section 3.07 hereof, it shall furnish to the Trustee, at least 45 days (unless a shorter period
shall be agreed to by the Trustee in writing) but not more than 75 days before a redemption date
(but in any event prior to the notice provided pursuant to Section 3.03 hereof), an Officers’
Certificate setting forth (i) the clause of this Indenture pursuant to which the redemption shall
occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the
redemption price.

Section 3.02. Selection of Notes to Be Redeemed.

          If less than all of the Notes are to be redeemed or purchased at any time, the Trustee shall
select the Notes to be redeemed or purchased among the Holders of the Notes in compliance with the
requirements of the principal national securities exchange, if any, on which the Notes are listed
or, if the Notes are not so listed, on a pro rata basis, by lot or in accordance with any other
method the Trustee considers fair and appropriate; provided, however, that if a partial redemption
is made with the proceeds of an Equity Offering, selection of the Notes or portions thereof for
redemption shall be made by the

-32-

 

 

Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject
to the procedures of the Depository), unless such method is prohibited. Any such determination by
the Trustee shall be conclusive. In the event of partial redemption by lot, the particular Notes
to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than
60 days prior to the redemption date by the Trustee from the outstanding Notes not previously
called for redemption.

          The Trustee shall promptly notify the Company in writing of the Notes selected for redemption
and, in the case of any Note selected for partial redemption, the principal amount thereof to be
redeemed. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of
$1,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding
amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except
as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for
redemption also apply to portions of Notes called for redemption.

Section 3.03. Notice of Redemption.

          Subject to the provisions of Sections 3.07 and 3.08 hereof, at least 30 days but not more than
60 days before an optional redemption date, the Company shall mail or cause to be mailed, by first
class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered
address.

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

     (a) the redemption date;

     (b) the redemption price;

     (c) if any Note is being redeemed in part, the portion of the principal amount of such
Note to be redeemed and that, after the redemption date upon surrender of such Note, a new
Note or Notes in principal amount equal to the unredeemed portion shall be issued upon
cancellation of the original Note;

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

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

     (f) that, unless the Company defaults in making such redemption payment, interest on
Notes called for redemption ceases to accrue on and after the redemption date;

     (g) the paragraph of the Notes or Section of this Indenture pursuant to which the Notes
called for redemption are being redeemed, and;

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

          At the Company’s request, the Trustee shall give the notice of redemption in the Company’s
name and at its expense; provided, however, that the Company shall have delivered to the Trustee at
least 30 days (unless a shorter period shall be agreed to by the Trustee in writing) but not more
than 60 days prior to the redemption date, an Officers’ Certificate requesting that the Trustee
give such notice and setting forth the information to be stated in such notice as provided in the
preceding paragraph.

-33-

 

 

Section 3.04. Effect of Notice of Redemption.

          Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for
redemption shall become irrevocably due and payable on the redemption date at the redemption price.
A notice of redemption may not be conditional.

          A notice of redemption shall be deemed to be given when mailed, whether or not the Holder
receives the notice. In any event, failure to give such notice, or any defect in such notice,
shall not affect the validity of the proceedings for the redemption of the Notes held by Holders to
whom such notice was properly given.

Section 3.05. Deposit of Redemption Price.

          On or prior to the redemption date, the Company shall deposit with the Trustee or with the
Paying Agent money sufficient to pay the redemption price of and accrued interest on all Notes to
be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any
money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts
necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed.

          If the Company complies with the provisions of the preceding paragraph, on and after the
redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for
redemption. If a Note is redeemed on or after an interest record date but on or prior to the
related interest payment date, then any accrued and unpaid interest shall be paid to the person in
whose name such Note was registered at the close of business on such record date. If any Note
called for redemption shall not be so paid upon surrender for redemption because of the failure of
the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal
from the redemption date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01
hereof.

Section 3.06. Notes Redeemed in Part.

          Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon receipt
of an Authentication Order in accordance with Section 2.02 with respect to such Notes, the Trustee
shall authenticate for the Holder at the expense of the Company a new Note equal in principal
amount to the unredeemed portion of the Note surrendered.

Section 3.07. Optional Redemption.

          (a) The Company may redeem any or all of the Notes at any time on or after August 15, 2010 at
the redemption prices set forth in paragraph 5 of the Note attached hereto.

          (b) From time to time, on or prior to August 15, 2008, the Company may, at its option, use the
net cash proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal
amount of the Notes issued under this Indenture at a redemption price of 106.125% of the principal
amount thereof, plus accrued and unpaid interest thereon, if any, and Liquidated Damages, if any,
to the date of redemption; provided that (i) at least 65% of the original principal amount of the
Notes issued under this Indenture shall remain outstanding immediately after each such redemption,
and (ii) the Company shall make such redemption not more than 90 days after the consummation of any
such Equity Offering.

-34-

 

 

          (c) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

Section 3.08. Repurchase at the Option of Holders.

          In the event that, pursuant to Section 4.15 or Section 4.16 hereof, the Company shall be
required to commence an offer to all Holders to purchase Notes (a “Repurchase Offer”), and they
shall follow the procedures specified below.

          The Repurchase Offer shall remain open for a period of 20 Business Days following its
commencement and no longer, except to the extent that a longer period is required by applicable law
(the “Offer Period”). No later than five Business Days after the termination of the Offer Period
(the “Purchase Date”), the Company shall purchase at the purchase price (as determined in
accordance with Section 4.15 hereof), the principal amount of Notes required to be purchased
pursuant to Section 4.15 hereof, in the aggregate (the “Offer Amount”) or, if less than the Offer
Amount has been tendered, all Notes tendered in response to such Repurchase Offer. Payment for any
Notes so purchased shall be made in the same manner as interest payments are made.

          If the Purchase Date is on or after an interest record date and on or before the related
interest payment date, any accrued and unpaid interest shall be paid to the person in whose name a
Note is registered at the close of business on such record date, and no additional interest shall
be payable to Holders who tender Notes pursuant to such Repurchase Offer.

          Upon the commencement of a Repurchase Offer, the Company shall send, by first class mail, a
notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice shall
contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to
such Repurchase Offer. The Repurchase Offer shall be made to all Holders. The notice, which shall
govern the terms of such Repurchase Offer, shall state:

     (a) that the Repurchase Offer is being made pursuant to this Section 3.08 and Section
4.15 or Section 4.16, as the case may be, hereof, and the length of time the Repurchase
Offer shall remain open;

     (b) the Offer Amount, the purchase price and the Purchase Date;

     (c) that any Note not tendered or accepted for payment shall continue to accrue
interest;

     (d) that, unless the Company default in making such payment, any Note accepted for
payment pursuant to the Repurchase Offer shall cease to accrue interest after the Purchase
Date;

     (e) that Holders electing to have a Note purchased pursuant to any Repurchase Offer may
elect to have Notes purchased in integral multiples of $1,000 only;

     (f) that Holders electing to have a Note purchased pursuant to any Repurchase Offer
shall be required to surrender the Note, with the form entitled “Option of Holder to Elect
Purchase” on the reverse of the Note completed, or transfer by book-entry transfer, to the
Company, a Depositary, if appointed by the Company, or a Paying Agent at the address
specified in the notice before the Purchase Date;

-35-

 

 

     (g) that Holders shall be entitled to withdraw their election if the Company, the
Depositary or the Paying Agent, as the case may be, receives, not later than the expiration
of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of the Notes the Holder delivered for purchase and
a statement that such Holder is withdrawing his election to have such Notes purchased; and

     (h) that, if the aggregate principal amount of Notes surrendered by Holders exceeds the
Offer Amount, the Notes shall be selected for purchase pursuant to the terms of this Section
3.08, and that Holders whose Notes were purchased only in part shall be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered (or
transferred by book-entry transfer).

          On or before the Purchase Date, the Company shall, to the extent lawful, accept for payment,
pursuant to the terms of this Section 3.08, the Offer Amount of Notes or portions thereof tendered
pursuant to the Repurchase Offer, or if less than the Offer Amount has been tendered, all Notes
tendered, and shall deliver to the Trustee an Officers’ Certificate stating that such Notes or
portions thereof were accepted for payment by the Company in accordance with the terms of this
Section 3.08. The Company, the Depositary or the Paying Agent, as the case may be, shall promptly
(but in any case not later than five Business days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and
accepted by the Company for purchase, and the Company shall promptly issue a new Note, and the
Trustee, upon receipt of an Authentication Order in accordance with Section 2.02 with respect to
such Note, shall authenticate and mail or deliver such new Note to such Holder, in a principal
amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly
announce through PR Newswire, Dow Businesswire or any comparable wire service that distributes
releases to the broad financial and investor media, the results of the Repurchase Offer on the
Purchase Date.

          The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act, and any
other securities laws and regulations thereunder to the extent that such laws or regulations are
applicable in connection with the repurchase of the Notes pursuant to the Repurchase Offer. To the
extent that the provisions of Rule 14e-1 under the Exchange Act or any securities laws or
regulations conflict with the provisions of this Section 3.08 or with Section 4.15 hereof, the
Company will comply with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under those sections of this Indenture.

          Any redemption pursuant to Article 3 hereof shall be subject to the provisions of Section
2.01. Notes called for redemption become due and payable on the date fixed for redemption.
Interest will cease to accrue on the Notes or portions thereof being redeemed on and after the
redemption date, unless the Company defaults in the payment of the redemption or repurchase price.

4.07(c), is less than or equal to the sum, without duplication, of:

     (A) 50% of the Company’s Consolidated Net Income for the period (taken as one
accounting period) from January 1, 2005 to the end of the Company’s most recently
ended fiscal quarter for which the Company has filed financial statements with the
Commission (or, if such Consolidated Net Income for such period is a deficit, less
100% of such deficit), plus

     (B) 100% of the aggregate net cash proceeds received by the Company since the
Issue Date as a contribution to the Company’s common equity capital or from the
issue or sale (other than to a Subsidiary) of the Company’s or any of its Restricted
Subsidiaries’ Equity Interests (other than Disqualified Stock) or from the issue or
sale (other than to a Subsidiary) of the Company’s convertible or exchangeable
Disqualified Stock or the Company’s convertible or exchangeable debt securities that
have been converted into or exchanged for Equity Interests (other than Disqualified
Stock), plus

     (C) to the extent that any Restricted Investment that the Company or any of its
Restricted Subsidiaries makes after the Issue Date is sold for cash or otherwise
liquidated or repaid for cash, an amount equal to the lesser of (1) the cash return
of capital with respect to any such Restricted Investment (less the cost of
disposition, if any) and (2) the initial amount of such Restricted Investment, plus

     (D) if the Company redesignates any Unrestricted Subsidiary as a Restricted
Subsidiary after the Issue Date, an amount equal to the lesser of (1) the net book
value of the Company’s Investment in the Unrestricted Subsidiary at the time the
Unrestricted Subsidiary was designated as such and (2) the fair market value of the
Company’s Investment in the Unrestricted Subsidiary at the time of the
redesignation.

          (c) Notwithstanding clauses (a) and (b) of this Section 4.07, the Company shall be permitted
to effect, and to cause or allow any of its Restricted Subsidiaries to effect:

     (i) the payment of any dividend within 60 days after the date of declaration of the
dividend, if at the date of declaration the dividend payment would have complied with the
provisions of this Indenture;

-40-

 

     (ii) the redemption, repurchase, retirement, defeasance or other acquisition of any of
(a) the Company’s Indebtedness or any Indebtedness of any Guarantor that is subordinated to
the Notes or the Subsidiary Guarantees, or (b) the Company’s Equity Interests or any Equity
Interests of any of the Company’s Restricted Subsidiaries, in either case in exchange for,
or out of the net cash proceeds of the substantially concurrent sale (other than to one of
the Company’s Subsidiaries) of, the Company’s Equity Interests (other than Disqualified
Stock); provided, however, that the amount of any such net cash proceeds that are utilized
for any such redemption, repurchase, retirement, defeasance or other acquisition will be
excluded from clause (c)(iii)(B) of this Section 4.07;

     (iii) the defeasance, redemption, repurchase or other acquisition of the Company’s
Indebtedness or Indebtedness of any Guarantor that is subordinated to the Notes or the
Subsidiary Guarantees with the net cash proceeds from an incurrence of Permitted Refinancing
Indebtedness;

     (iv) the payment of any dividend by one of the Company’s Restricted Subsidiaries to the
holders of that Restricted Subsidiary’s common Equity Interests on a pro rata basis, so long
as the Company or one of its Restricted Subsidiaries receives at least a pro rata share (and
in like form) of the dividend or distribution in accordance with its common Equity
Interests;

     (v) the repurchase, redemption or other acquisition or retirement for value of any of
the Company’s or any of its Restricted Subsidiaries’ Equity Interests held by any member of
the Company’s or any of its Restricted Subsidiaries’ management pursuant to any management
equity subscription agreement, stock option agreement or similar agreement, provided,
however, that the aggregate price paid for all such repurchased, redeemed, acquired or
retired Equity Interests may not exceed $5.0 million in any twelve-month period;

     (vi) in connection with an acquisition by the Company or any of its Restricted
Subsidiaries, the return to the Company or such Restricted Subsidiary of Equity Interests of
the Company or such Restricted Subsidiary constituting a portion of the purchase
consideration in settlement of indemnification claims;

     (vii) the purchase by the Company of fractional shares arising out of stock dividends,
splits or combinations or business combinations;

     (viii) repurchases of Equity Interests deemed to occur upon exercise of stock options
or warrants if such Equity Interests represent a portion of the exercise price of such
options or warrants or the payment of withholding taxes through the issuance of Equity
Interests;

     (ix) the acquisition in open-market purchases of the Company’s common Equity Interests
for matching contributions to the Company’s employee stock purchase and deferred
compensation plans in the ordinary course of business and consistent with past practices; or

     (x) other Restricted Payments in an aggregate amount since the Issue Date not to exceed
$35.0 million,

provided, however, that, with respect to clauses (ii), (iii), (v), (ix) and (x) above, no Default
or Event of Default shall have occurred and be continuing immediately after such transaction.

          (d) For the avoidance of doubt, any cash payment on any Indebtedness convertible into Capital
Stock (other than Disqualified Stock) in an amount not in excess of the aggregate principal amount
thereof shall not be deemed a “Restricted Payment” under this Section 4.07; provided that such

-41-

 

payment was a scheduled payment included in the instrument relating to such Indebtedness upon
original issuance thereof. The amount of all Restricted Payments (other than cash) will be the
fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to
be transferred or issued by the Company or a Restricted Subsidiary, as the case may be, pursuant to
the Restricted Payment. The fair market value of any assets or securities that are required to be
valued by this Section 4.07 will be determined by the Company’s Board of Directors whose resolution
with respect thereto will be delivered to the Trustee. The Board of Directors’ determination must
be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm
of national standing if the fair market value exceeds $20.0 million. Not later than the date of
making any Restricted Payment, the Company shall deliver to the Trustee an Officers’ Certificate
stating that such Restricted Payment is permitted and setting forth the basis upon which the
calculations required by this Section 4.07 were computed, together with a copy of any fairness
opinion or appraisal required by this Indenture.

Section 4.08. Dividend and Other Payment Restrictions Affecting
Subsidiaries.

          (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to,
directly or indirectly, create or permit to exist or become effective any consensual encumbrance or
restriction on the ability of any Restricted Subsidiary of the Company to (i)(A) pay dividends or
make any other distributions on any Capital Stock of such Restricted Subsidiary to the Company or
any other Restricted Subsidiary, or with respect to any other interest or participation in, or
measured by, the profits of such Restricted Subsidiary, or (B) pay any Indebtedness owed to the
Company or any other Restricted Subsidiary, (ii) make loans or advances to the Company or any other
Restricted Subsidiary, or (iii) transfer any of its properties or assets to the Company or any
other Restricted Subsidiary.

          (b) The provisions of Section 4.08(a) above shall not apply to encumbrances or restrictions
existing under or by reason of:

     (i) agreements governing Existing Indebtedness, or any Credit Facilities, as in effect
on the Issue Date and any amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacements or refinancings of those agreements, provided that the
amendments, modifications, restatements, renewals, increases, supplements, refundings,
replacement or refinancings of any of the foregoing are no more restrictive, taken as a
whole, with respect to such dividend and other payment restrictions than those contained in
those agreements on the date hereof;

     (ii) this Indenture, the Notes and the Subsidiary Guarantees, or any other indenture
governing debt securities that are no more restrictive, taken as a whole, with respect to
dividend and other payment restrictions than those contained in this Indenture and the
Notes;

     (iii) applicable law or any applicable rule, regulation or order;

     (iv) any instrument governing Indebtedness or Capital Stock of a person acquired by the
Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition
(except to the extent such Indebtedness or Capital Stock was incurred in connection with or
in contemplation of such acquisition), which encumbrance or restriction is not applicable to
any person, or the properties or assets of any person, other than the person, or the
property or assets of the person, so acquired, provided that, in the case of Indebtedness,
such Indebtedness was permitted by the terms of this Indenture to be incurred;

-42-

 

     (v) customary non-assignment provisions in leases entered into in the ordinary course
of business and consistent with past practices;

     (vi) purchase money obligations for property acquired in the ordinary course of
business that impose restrictions on that property of the nature described in clause
(a)(iii) of this Section 4.08;

     (vii) any agreement (A) for the sale or other disposition of all of the Equity
Interests in or all or substantially all of the assets of one of the Company’s Restricted
Subsidiaries that restricts distributions or asset transfers by that Restricted Subsidiary
pending that sale or other disposition or (B) for the sale of a particular asset or line of
business of a Restricted Subsidiary that imposes restrictions on the property subject to an
agreement of the nature described in clause (a)(iii) of this Section 4.08;

     (viii) Permitted Refinancing Indebtedness, provided that any restrictions contained in
the agreements governing such Permitted Refinancing Indebtedness are not materially more
restrictive, taken as a whole, than those contained in the agreements governing the
Indebtedness being refinanced and that such Permitted Refinancing Indebtedness was permitted
to be incurred under Section 4.09 hereof;

     (ix) any instrument governing Indebtedness of a Foreign Restricted Subsidiary permitted
to be incurred pursuant to Section 4.09 hereof;

     (x) Liens securing Indebtedness otherwise permitted to be incurred under the provisions
of Section 4.11 that limit the right of the debtor to dispose of the assets subject to such
Liens; and

     (xi) provisions with respect to the disposition of specific assets or property in asset
sale agreements entered into in the ordinary course of business.

Section 4.09. Incurrence of Indebtedness and Issuance of Preferred Stock.

          (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, incur
any Indebtedness (including Acquired Debt), and the Company shall not issue any Disqualified Stock,
and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred stock;
provided, however, that (1) the Company and any Guarantor may incur Indebtedness (including
Acquired Debt) and (2) the Company may issue Disqualified Stock, if, in each case, the Fixed Charge
Coverage Ratio for the Company’s most recently ended fiscal four full fiscal quarters for which the
Company has filed financial statements with the Commission preceding the date on which such
additional Indebtedness is incurred or such Disqualified Stock is issued, as the case may be, would
have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application
of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the
Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter
period.

          (b) In addition to the foregoing, the Company and any Restricted Subsidiary (except as
specified below) may incur the following types of Indebtedness (collectively, “Permitted Debt”):

     (i) the incurrence by the Company or any Restricted Subsidiary of additional
Indebtedness and letters of credit under one or more Credit Facilities and guarantees
thereof by the Guarantors; provided, however, that the aggregate principal amount of all
Indebtedness incurred by the Company and its Restricted Subsidiaries pursuant to this clause
(i) (with letters of credit

-43-

 

being deemed to have a principal amount equal to the maximum potential liability of the
Company and its Restricted Subsidiaries thereunder) outstanding at any one time does not
exceed $400.0 million;

     (ii) the incurrence by the Company and the Restricted Subsidiaries of the Existing
Indebtedness;

     (iii) the incurrence by the Company of Indebtedness represented by the Notes issued on
the Issue Date and the incurrence by the Guarantors of the Subsidiary Guarantees of those
Notes;

     (iv) the incurrence by the Company, or by any Restricted Subsidiary that is a
Guarantor, of Indebtedness represented by Capital Lease Obligations, mortgage financings or
purchase money obligations, in each case incurred for the purpose of financing all or any
part of the purchase price or cost of construction or improvement of property, plant or
equipment used in the Company’s business or the business of that Restricted Subsidiary, in
an aggregate principal amount not to exceed the greater of (x) $30.0 million at any time
outstanding and (y) 3.5% of Total Assets at the time of such incurrence of such
Indebtedness;

     (v) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted
Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund,
refinance or replace Indebtedness (other than intercompany Indebtedness) that was incurred
under clause (a) of this Section 4.09 or clauses (ii), (iii) or (iv) of this Section
4.09(b); provided, however, that no Restricted Subsidiary that is not a Guarantor may
refund, refinance or replace Indebtedness previously incurred by the Company or by any
Restricted Subsidiary that is a Guarantor;

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

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

     (B) (1) any subsequent issuance or transfer of Equity Interests that results in
any such Indebtedness being held by a person other than the Company or a Restricted
Subsidiary that is a Guarantor and (2) any sale or other transfer of any such
Indebtedness to a person that is not either the Company or a Restricted Subsidiary
that is a Guarantor shall be deemed, in each case, to constitute an incurrence of
such Indebtedness by the Company or such Restricted Subsidiary, as the case may be,
that was not permitted by this clause (vi);

     (vii) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging
Obligations;

     (viii) Indebtedness of the Foreign Restricted Subsidiaries that are not Guarantors in
an aggregate principal amount not to exceed the greater of (x) $75.0 million and (y) 7.5% of
Total Assets at the time of incurrence of such Indebtedness;

-44-

 

     (ix) the guarantee by the Company or any of the Guarantors of Indebtedness of the
Company or of any of the Guarantors that was permitted to be incurred by another provision
of this Section 4.09; and

     (x) the incurrence by the Company or a Restricted Subsidiary of additional Indebtedness
in an aggregate principal amount (or accreted value, as applicable) at any time outstanding,
including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace
any Indebtedness incurred pursuant to this clause (x), not to exceed $50.0 million.

          (c) The maximum amount of Indebtedness that the Company or a Restricted Subsidiary may incur
pursuant to this Section 4.09 shall not be deemed to be exceeded, with respect to any outstanding
Indebtedness, due solely to fluctuations in the exchange rates of currencies.

          (d) For purposes of determining compliance with this covenant, in the event that an item of
proposed Indebtedness, including Acquired Debt, meets the criteria of more than one of the
categories of Permitted Debt described in clauses (b)(i) through (x) of this Section 4.09 as of the
date of incurrence thereof, or is entitled to be incurred pursuant to clause (a) of this Section
4.09 as of the date of incurrence thereof or pursuant to any combination of the foregoing as of the
date of incurrence thereof, the Company shall, in its sole discretion, classify (or later classify
or reclassify) in whole or in part, in the Company’s sole discretion, such item of Indebtedness in
any manner that complies with this Section 4.09. Accrual of interest or dividends, the accretion
of accreted value or liquidation preference and the payment of interest or dividends in the form of
additional Indebtedness or Disqualified Stock will not be deemed to be an incurrence of
Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.09.

Section 4.10. Transactions with Affiliates.

          (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make
any payment to, or sell, lease, transfer or otherwise dispose of any properties or assets to, or
purchase any property or assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate
(each, an “Affiliate Transaction”), unless:

     (i) the Affiliate Transaction is on terms that are no less favorable to the Company or
the relevant Restricted Subsidiary than those that would have been obtained in a comparable
transaction by the Company or such Restricted Subsidiary with an unrelated person; and

     (ii) the Company delivers to the Trustee:

     (A) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $5.0 million, a
resolution of the Company’s Board of Directors set forth in an Officers’ Certificate
certifying that such Affiliate Transaction complies with this Section 4.10 and that
such Affiliate Transaction has been approved by a majority of the disinterested
members of the Company’s Board of Directors; and

     (B) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $10.0 million, an
opinion as to the fairness to the Holders of such Affiliate Transaction from a
financial point of view issued by an accounting, appraisal or investment banking
firm of national standing.

-45-

 

          (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will
not be subject to the provisions of clause (a) of this Section 4.10:

     (i) any employment agreement entered into by the Company or a Restricted Subsidiary in
the ordinary course of business and consistent with the past practice of the Company or such
Restricted Subsidiary;

     (ii) transactions between or among the Company and/or its Restricted Subsidiaries;

     (iii) transactions with a person that is an Affiliate of the Company solely because the
Company owns an Equity Interest in such person;

     (iv) payment of reasonable directors fees and reasonable indemnitees to persons who are
not otherwise Affiliates of the Company;

     (v) sales of Equity Interests (other than Disqualified Stock) to Affiliates of the
Company;

     (vi) Restricted Payments or Permitted Investments that are permitted by Section 4.07;
or

     (vii) transactions in the ordinary courses of business consistent with the past
practices with persons that one of the Company’s directors serves as an officer or director
of such person.

Section 4.11. Liens.

          The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, assume or suffer to exist any Lien of any kind securing Indebtedness,
Attributable Debt or trade payables, except Permitted Liens, upon any of the Company’s, or a
Restricted Subsidiary’s, property or assets, now owned or acquired after the Issue Date, unless all
payments due under this Indenture and the Notes, or the Subsidiary Guarantees, as applicable, are
secured on an equal and ratable basis with (or if the obligations being secured rank junior in
right of payment to the Notes, on a senior basis to) the obligations so secured until such time as
such obligations are no longer secured by a Lien.

Section 4.12. Additional Subsidiary Guarantees.

          On the Issue Date, each of the Company’s Domestic Subsidiaries shall execute a Subsidiary
Guarantee.

          If the Company or any Restricted Subsidiary acquires or creates another Domestic Subsidiary on
or after the Issue Date, then that newly acquired or created Domestic Subsidiary will become a
Guarantor and execute a supplemental indenture and deliver an Opinion of Counsel satisfactory to
the Trustee within ten Business Days of the date on which it was acquired or created; provided,
however, that the foregoing shall not apply to Subsidiaries that have properly been designated as
Unrestricted Subsidiaries in accordance with this Indenture for so long as they continue to
constitute Unrestricted Subsidiaries; provided further, however, that if a Subsidiary that is not a
Guarantor guarantees any of the Company’s or a Guarantor’s Indebtedness, that Subsidiary will be
required to provide the Company with a guarantee that ranks pari passu with (or, if that
Indebtedness is subordinated Indebtedness, prior to) that Indebtedness.

-46-

 

Section 4.13. Designation of Restricted and Unrestricted Subsidiaries.

          (a) The Board of Directors of the Company may designate any Restricted Subsidiary (or any
person that upon its acquisition otherwise would become a Restricted Subsidiary) to be an
Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary
is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding
Investments owned by the Company and the Restricted Subsidiaries in the Subsidiary properly
designated will be deemed to be an Investment made as of the time of the designation and will
reduce the amount available for Restricted Payments under Section 4.07(a) or Permitted Investments,
as determined by the Company. That designation will only be permitted if the Investment would be
permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an
Unrestricted Subsidiary. The Board of Directors of the Company may redesignate any Unrestricted
Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default.

          (b) Any designation of any of the Company’s Subsidiaries as an Unrestricted Subsidiary
pursuant to this Section 4.13 shall be evidenced to the Trustee by filing with the Trustee a
certified copy of the Board Resolution giving effect to such designation and an Officers’
Certificate certifying that such designation complied with the preceding conditions and was
permitted by Section 4.07. If, at any time, any Unrestricted Subsidiary would fail to meet the
preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an
Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary
shall be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness
is not permitted to be incurred as of such date under Section 4.09, the Company shall be in default
of such Section 4.09. The Company’s Board of Directors may at any time designate any Unrestricted
Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an
incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such
Unrestricted Subsidiary and such designation will only be permitted if (1) such Indebtedness is
permitted under Section 4.09 calculated on a pro forma basis as if such designation had occurred at
the beginning of the four-quarter reference period; and (2) no Default or Event of Default would be
in existence following such designation.

Section 4.14. Corporate Existence.

          Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to
preserve and keep in full force and effect (i) its corporate existence, and the corporate,
partnership or other existence of each of its Restricted Subsidiaries, in accordance with the
respective organizational documents (as the same may be amended from time to time) of the Company
or any such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and
franchises of the Company and its Restricted Subsidiaries; provided, however, that the Company
shall not be required to preserve any such right, license or franchise, or the corporate,
partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors
shall determine that the preservation thereof is no longer desirable in the conduct of the business
of the Company and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not
adverse in any material respect to the Holders of the Notes.

Section 4.15. Asset Sales.

          (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to,
consummate an Asset Sale unless:

     (i) the Company, or the Restricted Subsidiary, as the case may be, receives
consideration at the time of the Asset Sale at least equal to the fair market value of the
assets or Equity Interests issued or sold or otherwise disposed of;

-47-

 

     (ii) in the case of Asset Sales for consideration exceeding $5.0 million, the fair
market value is determined by the Company’s Board of Directors and evidenced by a resolution
of the Company’s Board of Directors set forth in an officer’s certificate delivered to the
Trustee; and

     (iii) at least 75% of the consideration received in the Asset Sale by the Company or
such Subsidiary is in the form of cash. For purposes of this provision, each of the
following will be deemed to be cash:

     (A) any secured Indebtedness of the Company or a Guarantor and any Indebtedness
of a Restricted Subsidiary that is not a Guarantor that are assumed by the
transferee of any such assets pursuant to a customary novation agreement that
releases the Company or such Restricted Subsidiary from further liability;

     (B) any securities, notes or other obligations received by the Company or any
Restricted Subsidiary from such transferee that the Company or such Restricted
Subsidiary within 180 days of receipt thereof, converts into cash, to the extent of
the cash received, in that conversion;

     (C) any Designated Non-cash Consideration received by the Company or any
Restricted Subsidiary in such Asset Sale having an aggregate fair market value (as
determined in good faith by the Company’s Board of Directors), taken together with
all other Designated Non-cash Consideration received pursuant to this clause (c)
that is at that time outstanding, not to exceed the greater of (x) $50.0 million and
(y) 5.0% of Total Assets at the time of the receipt of such Designated Non-cash
Consideration (with the fair market value of each item of Designated Non-cash
Consideration being measured at the time received without giving effect to
subsequent changes in value); and

     (D) Liquid Securities.

          (b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company may
apply those Net Proceeds at its option:

     (i) to permanently repay any secured Indebtedness of the Company or a Guarantor, or any
Indebtedness of a Restricted Subsidiary that is not a Guarantor and, if any Indebtedness
repaid under this clause (i) is revolving credit Indebtedness, to correspondingly reduce
commitments with respect thereto; provided, however, that for purposes of this clause (i)
only, Indebtedness shall include accrued but unpaid interest thereon;

     (ii) to acquire all or substantially all of the assets of, or a majority of the Voting
Stock of, another Permitted Business;

     (iii) to make a capital expenditure;

     (iv) to acquire other long-term assets that are used or useful in a Permitted Business;
or

     (v) make a Permitted Investment.

Pending the final application of any Net Proceeds, the Company may temporarily reduce revolving
credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this
Indenture.

-48-

 

          (c) Any Net Proceeds from Asset Sales that are not applied or invested as provided in the
preceding paragraph shall constitute “Excess Proceeds.” When the aggregate amount of Excess
Proceeds exceeds $20.0 million, the Company shall make a pro rata offer to purchase (an “Asset Sale
Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the
Notes containing provisions similar to those set forth in this Indenture with respect to offers to
purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of
Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The
offer price in any Asset Sale Offer will be equal to 100% of principal amount plus accrued and
unpaid interest to the date of purchase, and will be payable in cash. If any Excess Proceeds
remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any
purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and
other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Trustee shall select the Notes and such other pari passu Indebtedness to be purchased
on a pro rata basis (based upon the aggregate principal amount of the Notes and such other pari
passu Indebtedness tendered). Upon completion of each Asset Sale Offer, the amount of Excess
Proceeds will be deemed to have been reset at zero.

          (d) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and
any other securities laws and regulations thereunder to the extent those laws and regulations are
applicable in connection with repurchases of Notes pursuant to an Asset Sale Offer. To the extent
that the provisions of any securities laws or regulations conflict with this Section 4.15, the
Company shall comply with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under this Section 4.15 by virtue of that conflict.

Section 4.16. Offer to Repurchase upon Change of Control.

          (a) Upon the occurrence of a Change of Control Triggering Event, each Holder shall have the
right to require the Company to make an offer (a “Change of Control Offer”) to each Holder to
repurchase all or any part, equal to $1,000 or an integral multiple of $1,000, of such Holder’s
Notes at an offer price in cash equal to 101% of the aggregate principal amount of Notes
repurchased, plus accrued and unpaid interest and Liquidated Damages, if any, on Notes repurchased
to the date fixed for repurchase (the “Change of Control Payment”).

          (b) Within 15 Business Days following a Change of Control Triggering Event, the Company shall
mail a notice to each Holder describing the transaction or transactions that constitute the Change
of Control Triggering Event and offering to repurchase the Notes on the date specified in the
notice, which date shall be no earlier than 30 days and no later than 60 days from the date the

14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent
those laws and regulations are applicable to the repurchase of the Notes as a result of a Change of
Control Triggering Event. To the extent that the provisions of any securities laws or regulations
conflict with this Section 4.16, the Company shall comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations under this Section 4.16 by
virtue of such conflict.

for payment all Notes or portions of Notes properly tendered under the Change of Control Offer;
(ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of
all Notes or portions of the Notes properly tendered; and (iii) deliver or cause to be delivered to

Change of Control Payment for such Notes, and, upon receipt of an Authentication Order in
accordance with Section 2.02 with respect to such Notes, the Trustee shall promptly authenticate
and deliver, or cause to be transferred by book entry, to each Holder a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered, if any, provided that each new Note
shall be in a principal amount of $1,000 or an integral multiple of $1,000.

          (e) The Change of Control provisions described in this Section 4.16 shall be applicable
whether or not any other provisions of this Indenture are applicable.

          (f) The Company shall not be required to make a Change of Control Offer following a Change of
Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in this Section 4.16 and
purchases all Notes properly tendered and not withdrawn under the Change of Control Offer.

Section 4.17. Limitations on Line of Business.

Section 4.18. Sale and Leaseback Transactions.

          (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, enter
into any sale and leaseback transaction; provided that the Company and its Restricted Subsidiaries
may enter into a sale and leaseback transaction if:

     (i) the Company or the relevant Restricted Subsidiary, as the case may be, could have
(A) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale
and leaseback transaction under the Fixed Charge Coverage Ratio test in Section 4.09(a) and
(B) incurred a Lien to secure such Indebtedness pursuant to Section 4.11; provided, however,
that clause (A) of this clause (a)(i) shall not be applicable at any time after the
occurrence of a Fall-away Event;

     (ii) the gross cash proceeds of the sale and leaseback transaction are at least equal
to the fair market value, as determined in good faith by the Company and set forth in an
Officers’ Certificate delivered to the Trustee, of the property that is the subject of the
sale and leaseback transaction; provided, however, that in the case of any sale and
leaseback transaction for consideration exceeding $10.0 million, the fair market value shall
be determined by the Company’s Board of Directors and set forth in an Officers’ Certificate
delivered to the Trustee; and

     (iii) the transfer of assets in the sale and leaseback transaction is permitted by, and
the Company or the relevant Restricted Subsidiary applies the proceeds of the transaction in
compliance with, Section 4.15 hereof; provided, however, that, in the event that the Company
or any of its Restricted Subsidiaries consummates a sale and leaseback transaction at any
time after the occurrence of a Fall-away Event, within twelve months of that sale and
leaseback transaction, the Company shall apply the Net Cash Proceeds thereof to permanently
repay secured Indebtedness of the Company or a Guarantor, or any Indebtedness of any of the
Company’s Restricted Subsidiaries that is not a Guarantor, and if any Indebtedness repaid
under this clause (a)(iii) is revolving credit Indebtedness, to correspondingly reduce
commitments with respect thereto.

or cause to be paid any consideration, whether by way of interest, fee or otherwise, to or for the
benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the
terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid
or is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the
solicitation documents relating to such consent, waiver or agreement.

Section 4.20. Suspension of Covenants.

          If on any date following the Issue Date the Notes have an Investment Grade Rating from both of

4.07, 4.08, 4.09, 4.10, 4.15, 4.17, 4.18(a)(i)(A) and 5.01(a)(iv) (collectively, the “Fall-away

Company is merged or to which such sale, assignment, transfer, conveyance or other disposition is
made shall succeed to, and be substituted for (so that from and after the date of such
consolidation, merger, sale, conveyance or other disposition, the provisions of this Indenture
referring to the “Company” shall refer instead to the successor corporation and not to the
Company), and may exercise every right and power of the Company under this Indenture with the same
effect as if such successor person had been named as the Company herein; provided, however, that
the predecessor Company shall not be relieved from the obligation to pay the principal of and
interest on the Notes or any other amounts owing hereunder or under the Notes in the case of a sale
or lease of all or substantially all of the Company’s assets that meets the requirements of Section

default or breach continues for a period of 60 days after written notice by the Trustee to
the Company or by the

-52-

 

Holders of 25% or more in aggregate principal amount of the Notes to the Company and
the Trustee;

     (f) default under any mortgage, indenture or instrument under which there may be issued
or by which there may be secured or evidenced any Indebtedness for money borrowed by the
Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the
Company or any of its Restricted Subsidiaries) whether such Indebtedness or guarantee now
exists, or is created after the date hereof, if that default:

     (i) is caused by a failure to pay principal of, or interest or premium, if any,
on such Indebtedness prior to the expiration of the grace period provided in such
Indebtedness on the date of such default (a “Payment Default”); or

     (ii) results in the acceleration of such Indebtedness prior to its express
maturity,

and, in each case, the principal amount of any such Indebtedness, together with the
principal amount of any other such Indebtedness under which there has been a Payment Default
or the maturity of which has been so accelerated, aggregates $10.0 million or more;

     (g) default by the Company or any of its Subsidiaries in the payment of final judgments
aggregating in excess of $10.0 million, which judgments are not paid, discharged or stayed
for a period of 60 days;

     (h) except as permitted by this Indenture, any Subsidiary Guarantee shall be held in
any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be
in full force and effect or any Guarantor, or any person acting on behalf of any Guarantor,
shall deny or disaffirm its obligations under its Subsidiary Guarantee;

     (i) a court having jurisdiction in the premises enters a decree or order for

     (i) relief in respect of the Company or any of its Restricted Subsidiaries in
an involuntary case under any applicable bankruptcy, insolvency or other similar law
now or hereafter in effect,

     (ii) appointment of a receiver, liquidator, assignee, custodian, trustee,
sequestrator or similar official of the Company or any of its Restricted
Subsidiaries or for all or substantially all of the property and assets of the
Company or any of its Restricted Subsidiaries, or

     (iii) the winding up or liquidation of the affairs of the Company or any of its
Restricted Subsidiaries and,

in each case, such decree or order shall remain unstayed and in effect for a period of 30
consecutive days; or

     (j) the Company or any of its Restricted Subsidiaries:

     (i) commences a voluntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect, or consents to the entry of an order
for relief in an involuntary case under any such law,

-53-

 

     (ii) consents to the appointment of or taking possession by a receiver,
liquidator, assignee, custodian, trustee, sequestrator or similar official of the
Company or such Restricted Subsidiary or for all or substantially all of the
property and assets of the Company or such Restricted Subsidiary, or

     (iii) effects any general assignment for the benefit of creditors.

Section 6.02. Acceleration.

          (a) If any Event of Default (other than an Event of Default specified in clause (i) or (j) of
Section 6.01 hereof) occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Notes, by written notice to the Company (and, if such
notice is given by such Holders, to the Trustee), may, and the Trustee at the request of such
Holders shall, declare the principal of, premium, if any, and accrued interest on the Notes to be
due and payable immediately. Upon such declaration of acceleration, such principal of, premium, if
any, and accrued and unpaid interest and Liquidated Damages, if any, shall be immediately due and
payable.

          (b) Notwithstanding the foregoing, if an Event of Default specified in clause (i) or (j) of
Section 6.01 hereof occurs with respect to the Company, any Restricted Subsidiary that is a
Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would
constitute a Significant Subsidiary, the principal of, premium, if any, and accrued and unpaid
interest and Liquidated Damages, if any, on the Notes then outstanding shall be due and payable
immediately without further action or notice on the part of the Trustee or any Holder.

Section 6.03. Other Remedies.

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

          The Trustee may maintain a proceeding to enforce its rights and to pursue its remedies under
the Notes and this Indenture even if the Trustee does not possess any of the Notes or does not
produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note
in exercising any right or remedy accruing upon an Event of Default shall not impair the right or
remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

Section 6.04. Waiver of Past Defaults.

          At any time after declaration of acceleration, but before a judgment or decree for the payment
of the money due has been obtained by the Trustee, the Holders of at least a majority in principal
amount of the outstanding Notes by written notice to the Company and to the Trustee, may waive all
past Defaults, except a Default in the payment of principal of, premium, if any, or interest on any
Note as specified in clause (a) or (b) of Section 6.01 or in respect of a covenant or provision of
this Indenture which cannot be modified or amended without the consent of the Holder of each
outstanding Note affected, and rescind and annul a declaration of acceleration and its consequences
if:

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

-54-

 

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

          Upon any such waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other Default or Event of Default or impair any right
consequent thereto.

Section 6.05. Control by Majority.

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

Section 6.06. Limitation on Suits.

          A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if:

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

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

     (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the
Trustee indemnity satisfactory to the Trustee against any loss, liability or expense;

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

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

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

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

          Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to
receive payment of principal, premium and Liquidated Damages, if any, and interest on the Note, on
or after the respective due dates expressed in the Note (including in connection with an offer to
purchase), or to bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

-55-

 

Section 6.08. Collection Suit by Trustee.

          If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the
Trustee is authorized to recover judgment in its own name and as Trustee of an express trust
against the Company for the whole amount of principal of, premium and Liquidated Damages, if any,
and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent
lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

Section 6.09. Trustee May File Proofs of Claim.

          The Trustee is authorized to file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall be entitled and
empowered to collect, receive and distribute any money or other property payable or deliverable on
any such claims and any custodian in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien
on, and shall be paid out of, and to secure the payment of same, the Trustee is hereby granted an
interest security in, any and all distributions, dividends, money, securities and other properties
that the Holders may be entitled to receive in such proceeding whether in liquidation or under any
plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any
plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of
any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

Section 6.10. Priorities.

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

     First: to the Trustee, its agents and attorneys for amounts due under Sections 6.09
and 7.07 hereof, including payment of all compensation, expense and liabilities incurred,
and all advances made, by the Trustee, its agents or attorneys and the costs and expenses of
collection;

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

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

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

-56-

 

Section 6.11. Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion
may require the filing by any party litigant in the suit of an undertaking to pay the costs of the
suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees and disbursements against any party litigant in the suit, having due regard to the merits and
good faith of the claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.06 hereof, or a suit by
Holders of more than 10% in principal amount of the then outstanding Notes.

Section 6.12. 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 Company, Trustee and the Holders shall continue as though no such proceeding had
been instituted, except that the rights of the Trustee to receive compensation, reimbursement of
any of its expenses or indemnification from the Holders in connection with such proceeding in
accordance with the terms of this Indenture or any separate agreement or understanding between the
Trustees and the Holders shall not be affected by this Section 6.12.

Section 6.13. Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or wrongfully taken Notes in Section 2.07, 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, or otherwise,
shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.14. Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing
upon any Event of Default 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 6 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.

ARTICLE 7.

TRUSTEE

Section 7.01. Duties of Trustee.

          (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of
the rights and powers of which the Trustee has actual knowledge vested in it by this Indenture,

-57-

 

           and use the same degree of care and skill in its exercise, as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.

          (b) Except during the continuance of an Event of Default of which the Trustee has actual
knowledge:

     (i) the duties of the Trustee shall be determined solely by the express provisions of
this Indenture or the TIA and the Trustee undertakes to perform, and need perform, only
those duties that are specifically set forth in this Indenture or the TIA and no others, and
no implied covenants or obligations shall be read into this Indenture against the Trustee;
and

     (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed therein, upon

whether or not they conform to the requirements of this Indenture.

negligent failure to act, or its own willful misconduct, except that:

expense.

          (f) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be
segregated from other funds except to the extent required by law.

          (a) In connection with its rights and duties under this Indenture, the Trustee may
conclusively rely and shall be fully protected in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order,
Note, or other document believed by it to be genuine and to have been signed or presented by the
proper person. The Trustee need not investigate any fact or matter stated in the document.

-58-

 

          (b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate
or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits
to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee
may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be
full and complete authorization and protection from liability in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon.

          (c) The Trustee may act through its attorneys and agents and shall not be responsible for the

expenses and liabilities that might be incurred by it in compliance with such request or direction.

          (g) The Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document,
but the Trustee, in its discretion, may make such further inquiry or investigation into such facts
or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises of the Company
personally or by agent or attorney.

          (h) Except with respect to Section 4.01, the Trustee shall have no duty to inquire as to the
performance of the Company’s covenants set forth in Article 4. The Trustee shall not be deemed to
have knowledge of any Default or Event of Default except (i) any Event of Default occurring
pursuant to Sections 6.01(a), 6.01(b) and 4.01 or (ii) any Default or Event of Default of which the
Trustee shall have received written notification in the manner set forth in this Indenture or a
Responsible Officer of the Trustee shall have obtained actual knowledge of the Default or Event of
Default.

Section 7.03. Individual Rights of Trustee.

          The Trustee in its individual or any other capacity may become the owner or pledgee of Notes
and may otherwise deal with the Company or any Affiliate of the Company with the same rights it
would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the Commission for permission to
continue as Trustee or resign. Any Agent may do the same with like rights and duties. The Trustee
is also subject to Sections 7.10 and 7.11 hereof.

-59-

 

Section 7.04. Trustee’s Disclaimer.

          The Trustee shall not be responsible for and makes no representation as to the validity or
adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the
proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any
provision of this Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be responsible for any
statement or recital herein or any statement in the Notes or any other document in connection with
the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

Section 7.05. Notice of Defaults.

          If a Default or Event of Default occurs and is continuing and if it is known to the Trustee,
the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90
days after it occurs. Except in the case of a Default or Event of Default in payment of principal
of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as
a committee of its Responsible Officers in good faith determines that withholding the notice is in
the interests of the Holders of the Notes.

Section 7.06. Reports by Trustee to Holders of the Notes.

          Within 60 days after each January 15 beginning with January 15, 2006, and for so long as Notes
remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of
such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has
occurred within the twelve months preceding the reporting date, no report need be transmitted).
The Trustee also shall comply with TIA § 313(b)(2). The Trustee shall also transmit by mail all
reports as required by TIA § 313(c).

          A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to
the Company and filed with the Commission and each stock exchange on which the Notes are listed in
accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are
listed on any stock exchange.

Section 7.07. Compensation and Indemnity.

          The Company shall pay to the Trustee from time to time such compensation for its acceptance of
this Indenture and services hereunder as shall be agreed upon in writing by the Company and the
Trustee. The Trustee’s compensation shall not be limited by any law on compensation of a Trustee
of an express trust. The Company shall reimburse the Trustee promptly upon request for all
reasonable disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee’s agents and counsel.

          The Company shall indemnify, defend and hold harmless the Trustee and its shareholders,
incorporators, directors, officers, employees, representatives and agents (each an “Indemnitee”)
against any and all losses, liabilities or expenses (including reasonable fees and disbursements of
counsel) incurred by any of them arising out of or in connection with the acceptance or
administration of the Trustee’s duties under this Indenture, including the costs and expenses of
enforcing this Indenture against the Company (including this Section 7.07) and defending any of
themselves against any claim (whether asserted by the Company or any Holder or any other person) or
liability in connection with the exercise or performance of any of the Trustee’s powers or duties
hereunder, except to the extent any such loss,

-60-

 

liability or expense or a portion thereof may be attributable to the Trustee’s negligence or bad
faith. An Indemnitee shall notify the Company promptly of any claim for which that Indemnitee may
seek indemnity. Failure by the Indemnitee to so notify the Company shall not relieve the Company
of its obligations hereunder. Subject to receipt of the consent of the party to be defended, which
consent shall not be unreasonable withheld or delayed, the Company shall defend the claim and the
Trustee shall cooperate in the defense. The Indemnitees may have separate counsel and the Company
shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any
settlement made without its consent, which consent shall not be unreasonably withheld or delayed.
The Company need not reimburse any expense or indemnify against any loss, liability or expense
incurred by an Indemnitee through that Indemnitee’s own willful misconduct, negligence or bad
faith.

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

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

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

          The Trustee shall comply with the provisions of TIA § 313(b)(2) to the extent applicable.

Section 7.08. Replacement of Trustee.

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

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

     (a) the Trustee fails to comply with Section 7.10 hereof;

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

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

     (d) the Trustee becomes incapable of acting.

          Subject to the provisions of TIA §310(b), if the Trustee resigns or is removed or if a vacancy
exists in the office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in
principal amount of the then outstanding Notes may appoint a successor Trustee to replace the
successor Trustee appointed by the Company.

-61-

 

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

          If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note
for at least six months, fails to comply with Section 7.10, such Holder of a Note may petition any
court of competent jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

          A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights, powers and duties of the
Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to
Holders of the Notes. Subject to the Lien provided for in Section 7.07 hereof, the retiring
Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee;
provided, however, that all sums owing to the retiring Trustee hereunder shall have been paid and
the property so transferred shall remain subject to the Lien provided for in Section 7.07.
Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations
under Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

Section 7.09. Successor Trustee by Merger, etc.

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

Section 7.10. Eligibility; Disqualification.

          There shall at all times be a Trustee hereunder that is a corporation organized and doing
business under the laws of the United States of America or of any state thereof that is authorized
under such laws to exercise corporate Trustee power, that is subject to supervision or examination
by federal or state authorities, and that has (or the bank holding company of which it is an
Affiliate has) a combined capital and surplus of at least $50.0 million as set forth in its most
recent published annual report of condition.

          This Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(1),
(2) and (5). The Trustee is subject to TIA § 310(b); provided, however, that there shall be
excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of the Company are
outstanding if the requirements for such exclusions set forth in TIA § 310(b)(1) are met.

Section 7.11. Preferential Collection of Claims Against Company.

          The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA §
311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent
indicated therein.

ARTICLE 8.

NOTE GUARANTEES

Section 8.01. Subsidiary Guarantees.

          (a) Subject to this Article 8, each of the Guarantors, from time to time party hereto, hereby,
jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and
delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the
validity and enforceability of this Indenture, the Notes or the obligations of the Company
hereunder or thereunder, that: (i) the principal of premium, if any, and interest on the Notes
will be promptly paid in full when due, whether at maturity, by acceleration, redemption or
otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful,
and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will
be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and
(ii) in case of any extension of time of payment or renewal of any Notes or any of such other
obligations, that same will be promptly paid in full when due or performed in accordance with the
terms of the extension or renewal, whether at stated maturity, by acceleration pursuant to Section
6.02 hereof or otherwise. Failing payment when due of any amount so guaranteed or any performance
so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay
the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a
guarantee of collection.

          (b) Each Guarantor hereby agrees that its obligations with regard to such Subsidiary Guarantee
shall be joint and several, unconditional, irrespective of the validity or enforceability of the
Notes or the obligations of the Company under this Indenture, the absence of any action to enforce
the same, the recovery of any judgment against the Company or any other obligor with respect to
this Indenture, the Notes or the obligations of the Company under this Indenture or the Notes, any
action to enforce the same or any other circumstances (other than complete performance) which might
otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor
further, to the extent permitted by law, waives and relinquishes all claims, rights and remedies
accorded by applicable law to guarantors and agrees not to assert or take advantage of any such
claims, rights or remedies, including but not limited to: (i) any right to require any of the
Trustee, the Holders or the Company (each, a “Benefited Party”), as a condition of payment or
performance by such Guarantor, to (A) proceed against the Company, any other guarantor (including
any other Guarantor) of the obligations under the Subsidiary Guarantees or any other person, (B)
proceed against or exhaust any security held from the Company, any such other guarantor or any
other person, (C) proceed against or have resort to any balance of any deposit account or credit on
the books of any Benefited Party in favor of the Company or any other person, or (D) pursue any
other remedy in the power of any Benefited Party whatsoever; (ii) any defense arising by reason of
the incapacity, lack of authority or any disability or other defense of the Company including any
defense based on or arising out of the lack of validity or the unenforceability of the obligations
under the Subsidiary Guarantees or any agreement or instrument relating thereto or by reason of the
cessation of the liability of the Company from any cause other than payment in full of the
obligations under the Subsidiary Guarantees; (iii) any defense based upon any statute or rule of
law which provides that the obligation of a surety must be neither larger in amount nor in other
respects more burdensome than that of the principal; (iv) any defense based upon any Benefited
Party’s errors or omissions in the administration of the obligations under the Subsidiary
Guarantees, except behavior which amounts to bad faith; (v)(A) any principles or provisions of law,
statutory or otherwise, which are or might be in conflict with the terms of the Subsidiary
Guarantees and any legal or equitable discharge of such Guarantor’s obligations hereunder, (B) the
benefit of any statute of limitations affecting such Guarantor’s liability hereunder or the
enforcement hereof, (C) any rights to set-offs, recoupments and counterclaims and (D) promptness,
diligence and any requirement that any Benefited Party protect, secure, perfect or insure any
security interest or lien or any

-63-

 

property subject thereto; (vi) notices, demands, presentations, protests, notices of protest,
notices of dishonor and notices of any action or inaction, including acceptance of the Subsidiary
Guarantees, notices of default under the Notes or any agreement or instrument related thereto,
notices of any renewal, extension or modification of the obligations under the Subsidiary
Guarantees or any agreement related thereto, and notices of any extension of credit to the Company
and any right to consent to any thereof; (vii) to the extent permitted under applicable law, the
benefits of any “One Action” rule and (viii) any defenses or benefits that may be derived from or
afforded by law which limit the liability of or exonerate guarantors or sureties, or which may
conflict with the terms of the Subsidiary Guarantees. Except as set forth in Section 8.05, each
Guarantor hereby covenants that its Subsidiary Guarantee will not be discharged except by complete
performance of the obligations contained in its Guarantee and this Indenture.

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

          (d) Each Guarantor agrees that it shall not be entitled to any right of subrogation in
relation to the Holders in respect of any obligations guaranteed hereby until payment in full of
all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors,
on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Section 6.02 hereof for the
purposes of any Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby and (ii) in the event
of any declaration of acceleration of such obligations as provided in Section 6.02 hereof, such
obligations (whether or not due and payable) shall forthwith become due and payable by the
Guarantors for the purpose of any such 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 applicable Subsidiary Guarantee.

Section 8.02. Additional Guarantees.

          If any Restricted Subsidiary becomes obligated pursuant to Section 4.12 hereof, then the
Company shall cause any such Restricted Subsidiary to, within ten Business Days of the date on
which any such Restricted Subsidiary became so obligated, (a) execute and deliver to the Trustee a
Supplemental Indenture in form reasonably satisfactory to the Trustee pursuant to which such
Restricted Subsidiary shall unconditionally guarantee, on a senior unsecured basis, all of the
Company’s obligations under the Notes and this Indenture on the terms set forth herein and therein
and (b) deliver to the Trustee an Opinion of Counsel that, subject to customary assumptions and
exclusions, such supplemental indenture has been duly executed and delivered by such Restricted
Subsidiary. Any Restricted Subsidiary that becomes a Guarantor shall remain a Guarantor unless (i)
designated an Unrestricted Subsidiary by the Company in accordance with this Indenture; (ii) is
otherwise released from its obligations as a Guarantor pursuant to Section 8.05 hereof; or (iii)
the circumstances giving rise to the obligation to provide a guarantee under Section 4.12 no longer
exist.

Section 8.03. 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 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. To effectuate the foregoing intention, the Trustee, the
Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor under
this Article 8 shall be limited to the

-64-

 

maximum amount as will, after giving effect to such maximum amount and all other contingent
and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect
to any collections from, rights to receive contribution from or payments made by or on behalf of
any other Guarantor in respect of the obligations of such other Guarantor under this Article 8,
result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a
fraudulent transfer or conveyance.

Section 8.04. Merger and Consolidation of Guarantors.

          Except as otherwise provided in Section 8.05 hereof, no Guarantor may sell or otherwise
dispose of all or substantially all of its assets to, or consolidate with or merge with or into
(whether or not such Guarantor is the surviving person) another person, other than the Company or
another Guarantor unless:

     (a) immediately after giving effect to such transaction, no Default or Event of Default
exists; and

     (b) either (i) the person acquiring the property in any such sale or disposition or the
person formed by or surviving any such consolidation or merger, assumes all the obligations
of that Guarantor under this Indenture and the Subsidiary Guarantee of such Guarantor
pursuant to a supplemental indenture reasonably satisfactory to the Trustee, or (ii) in the
case of a sale or other disposition of all or substantially all of the assets of such
Guarantor’s assets, the Net Proceeds of such sale of other disposition are applied in
accordance with Section 4.15.

          In case of any such sale or other disposition, consolidation, merger, sale or conveyance and
upon the assumption by the successor person, by supplemental indenture, executed and delivered to
the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee endorsed upon the
Notes and the due and punctual performance of all of the covenants and conditions of this Indenture
to be performed by the Guarantor, such successor person shall succeed to and be substituted for the
Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor
person thereupon may cause to be signed any or all of the Subsidiary Guarantees to be endorsed upon
all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee. All the Subsidiary Guarantees so issued shall in all respects have the
same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and
thereafter issued in accordance with the terms of this Indenture as though all of such Subsidiary
Guarantees had been issued at the date of the execution hereof.

          Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (a) and (b) of
this Section 8.04, nothing contained in this Indenture or in any of the Notes shall prevent any
consolidation or merger of a Guarantor with or into an Company or another Guarantor, or shall
prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an
entirety to an Company or another Guarantor.

Section 8.05. Release.

          (a) In the event of (i) a sale or other disposition of all or substantially all of the assets
of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of
all to the Capital Stock of any Guarantor, in each case to a person that is not (either before or
after giving effect to such transactions) a Subsidiary of the Company, so long as the Net Proceeds
of such sale or other disposition are applied in accordance with the applicable provisions of this
Indenture, including without limitation Section 4.15 hereof, or (ii) a designation by the Company
of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with
Section 4.13, such Guarantor or, in the case of a

-65-

 

sale or other disposition of all or substantially all of the assets of such Guarantor, the
corporation acquiring such property, will be released and relieved of any obligations under its
Subsidiary Guarantee.

          (b) Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of
Counsel to the effect that such sale or other disposition was made by the Company in accordance
with the provisions of this Indenture, including without limitation Section 4.07 hereof, or such
designation was made in accordance with Section 4.13 hereof, as the case may be, the Trustee shall
execute any documents reasonably required in order to evidence the release of any Guarantor from
its obligations under its Subsidiary Guarantee.

          (c) Any Guarantor not released from its obligations under its Subsidiary Guarantee shall
remain liable for the full amount of principal of and interest on the Notes and for the other
obligations of any Guarantor under this Indenture as provided in this Article 8.

ARTICLE 9.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 9.01. Option to Effect Legal Defeasance or Covenant Defeasance.

          The Company may, at the option of its Board of Directors evidenced by a resolution set forth
in an Officers’ Certificate, at any time, elect to have either Section 9.02 or 9.03 hereof be
applied to all outstanding Notes upon compliance with the conditions set forth below in this
Article 9.

Section 9.02. Legal Defeasance and Discharge.

          Upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section
9.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 9.04
hereof, be deemed to have been discharged from its obligations with respect to all outstanding
Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”).
For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and
discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be
deemed to be “outstanding” only for the purposes of Section 9.05 hereof and the other Sections of
this Indenture referred to in clauses (a) through (d) below, and to have satisfied all their other
obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense
of the Company, shall execute proper instruments acknowledging the same), except for the following
provisions which shall survive until otherwise terminated or discharged hereunder:

     (a) the rights of Holders to receive payments in respect of the principal of, premium,
if any, and interest on the Notes when such payments are due;

     (b) the Company’s obligations with respect to the Notes concerning issuing temporary
Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance
of an office or agency for payments;

     (c) the rights, powers, trust, duties and immunities of the Trustee and the Company’s
obligations in connection therewith; and

     (d) the Legal Defeasance provisions of this Article 9.

-66-

 

          Subject to compliance with this Article 9, the Company may exercise its option under this
Section 9.02, notwithstanding the prior exercise of its option under Section 9.03 hereof.

Section 9.03. Covenant Defeasance.

          Upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section
9.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 9.04
hereof, be released from its obligations under the covenants contained in Sections 4.07 through
4.13 and 4.15 through 4.20 hereof, both inclusive, and Section 5.01(a)(iv) with respect to the
outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter,
“Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes
of any direction, waiver, consent or declaration or act of holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all
other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for
accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Notes, the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant, whether directly or indirectly,
by reason of any reference elsewhere herein to any such covenant or by reason of any reference in
any such covenant to any other provision herein or in any other document, and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except
as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In
addition, upon the Company’s exercise under Section 9.01 hereof of the option applicable to this
Section 9.03, subject to the satisfaction of the conditions set forth in Section 9.04 hereof,
Sections 6.01(e), 6.01(g) and 6.01(i) hereof shall not constitute Events of Default.

          The following are the conditions precedent to the application of either Section 9.02 or 9.03
hereof to the outstanding Notes:

the Holders cash in U.S. dollars, non-callable U.S. Government Securities, or a combination
thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized

premium, if any, and interest on, the Notes on the stated date for payment thereof or on the
applicable redemption date, as the case may be;

     (2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an

Revenue Service a ruling; or

     (b) since the date of this Indenture, there has been a change in the applicable
federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm
that, the Holders will not recognize income, gain or loss for federal income tax purposes as
a result of such Legal Defeasance and will be subject to federal income tax on the same
amounts, in the same

-67-

 

manner and at the same times as would have been the case if such Legal Defeasance had not
occurred;

     (3) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee
an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming
that the Holders will not recognize income, gain or loss for federal income tax purposes as
a result of such Covenant Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if such
Covenant Defeasance had not occurred;

     (4) no Default or Event of Default shall have occurred and be continuing on the date of
such deposit or insofar as Events of Default from bankruptcy or insolvency events are

such deposit and the grant of any Lien securing such borrowings);

     (5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or
violation of, or constitute a default under this Indenture (other than a Default or an Event
of Default resulting from the borrowing of funds to be applied to such deposit and the grant
of any Lien securing such borrowings) or any other material agreement or instrument to which
the Company or any of its Subsidiaries is a party or by which the Company or any of its
Subsidiaries is bound;

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

     (7) the Company shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent provided for or relating to
the Legal Defeasance or the Covenant Defeasance have been complied with; and

     (8) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect
that, assuming no intervening bankruptcy of the Company between the date of deposit and the
91st day following the date of deposit and that no Holder is an insider of the Company,
after the 91st day following the date of deposit, the trust funds will not be subject to the
effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting
creditors’ rights generally.

          Notwithstanding the foregoing, the Opinion of Counsel required by clause (2) above with
respect to a Legal Defeasance need not be delivered if all Notes not theretofore delivered to the
Trustee for cancellation (1) have become due and payable or (2) will become due and payable on the
maturity date within one year under arrangements satisfactory to the Trustee for the giving of
notice of redemption by the Trustee in the name, and at the expense, of the Company.

Section 9.05. Deposited Money and U.S. Government Securities to Be Held in Trust; Other Miscellaneous Provisions.

     Subject
to Section 9.06 hereof, all money and U.S. Government Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 9.05 only, the “Trustee”) pursuant to
Section 9.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Notes and this

-68-

 

Indenture, to the payment, either
directly or through any Paying Agent (other than the Company) as the Trustee may determine, to the
Holders of such Notes of all sums due and to become due thereon in respect of principal or
redemption price of, and Liquidated Damages, if any, interest on, the Notes, that such money need
not be segregated from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the cash or U.S. Government Securities deposited pursuant to Section 9.04
hereof or the principal and interest received in respect thereof other than any such tax, fee or
other charge which by law is for the account of the Holders of the outstanding Notes.

          Anything in this Article 9 to the contrary notwithstanding, the Trustee shall deliver or pay
to the Company from time to time upon the request of the Company any money or U.S. Government
Securities held by it as provided in Section 9.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section 9.04(1) hereof), are in
excess of the amount thereof that would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance.

Section 9.06. Repayment to the Company.

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

Section 9.07. Reinstatement.

          If the Trustee or Paying Agent is unable to apply any United States dollars or U.S. Government
Securities in accordance with Section 9.02 or 9.03 hereof, as the case may be, by reason of any
order of judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the obligations of the Company under this Indenture, and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 9.02 or
9.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 9.02 or 9.03 hereof, as the case may be; provided, however, that, if the
Company makes any payment with respect to any Note following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment
from the money held by the Trustee or Paying Agent.

ARTICLE 10.

AMENDMENT, SUPPLEMENT AND WAIVER

Section 10.01. Without Consent of Holders of Notes.

          Notwithstanding Section 10.02 of this Indenture, the Company, the Guarantors and the Trustee
may amend or supplement this Indenture or the Notes without the consent of any Holder of a Note:

     (a) to cure any ambiguity, defect or inconsistency;

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

     (c) to provide for the assumption of the Company’s obligations to the Holders of the
Notes by a successor to the Company pursuant to Article 5 hereof;

     (d) to make any change that would provide any additional rights or benefits to the
Holders of the Notes or that does not adversely affect the legal rights hereunder of any
Holder of the Note; or

     (e) to comply with requirements of the Commission in order to effect or maintain the
qualification of this Indenture under the TIA.

          Upon the request of the Company accompanied by a resolution of its Board of Directors
authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the
Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company
in the execution of any amended or supplemental Indenture authorized or permitted by the terms of
this Indenture and to make any further appropriate agreements and stipulations that may be therein
contained, but the Trustee shall not be obligated to enter into such amended or supplemental
Indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 10.02. With Consent of Holders of Notes.

          (a) Except as provided below in this Section 10.02, this Indenture and the Notes may be
amended or supplemented with the consent of the Holders of at least a majority in principal amount
of the Notes then outstanding voting as a single class (including, without limitation, consents
obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and,
subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a
Default or Event of Default in the payment of the principal of, premium, if any, or interest on the
Notes, except a payment default resulting solely from an acceleration that has been rescinded) or
compliance with any provision of this Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes voting as a single class
(including consents obtained in connection with a tender offer or exchange offer for, or purchase
of, the Notes). However, without the consent of each Holder affected, an amendment or waiver under
this Section 10.02 may not (with respect to any Notes held by a non-consenting Holder):

     (i) reduce the principal amount of Notes whose Holders must consent to an amendment,
supplement or waiver;

-70-

 

     (ii) reduce the principal of or change the fixed maturity of any Note or alter the
provisions with respect to the redemption of the Notes, other than Sections 4.15 and 4.16;

     (iii) reduce the rate of or change the time for payment of interest on any Note;

     (iv) waive a Default or Event of Default in the payment of principal of, or interest or
premium, if any, on the Notes (except a rescission of acceleration of the Notes by the
Holders of at least a majority in aggregate principal amount of the Notes and a waiver of
the payment default that resulted from such acceleration);

     (v) make any Note payable in money other than that stated in the Notes;

     (vi) make any change in the provisions of this Indenture relating to waivers of past
Defaults, including Section 6.04, or the rights of holders of notes to receive payments of
principal of, or interest or premium, if any, on, the Notes;

     (vii) waive a redemption payment with respect to any Note, other than a payment
required under Section 4.15 or 4.16;

     (viii) release any Guarantor from any of its obligations under its Subsidiary Guarantee
or this Indenture, except in accordance with the terms of this Indenture; or

     (ix) make any change in the preceding amendment and waiver provisions.

          (b) Upon the request of the Company accompanied by a resolution of its Board of Directors
authorizing the execution of any such amended or supplemental Indenture, and upon the filing with
the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the
Trustee shall join with the Company in the execution of such amended or supplemental Indenture
unless such amended or supplemental Indenture directly affects the Trustee’s own rights, duties or
immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture.

          (c) It shall not be necessary for the consent of the Holders of Notes under this Section 10.02
to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if
such consent approves the substance thereof.

          (d) After an amendment, supplement or waiver under this Section becomes effective, the Company
shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment,
supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall
not, however, in any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in
aggregate principal amount of the Notes then outstanding voting as a single class may waive
compliance in a particular instance by the Company with any provision of this Indenture or the
Notes.

Section 10.03. Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended
or supplemental Indenture that complies with the TIA as then in effect.

-71-

 

Section 10.04. Revocation and Effect of Consents.

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

Section 10.05. Notation on or Exchange of Notes.

          The Trustee may place an appropriate notation about an amendment, supplement or waiver on any
Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee
shall, upon receipt of an Authentication Order, in accordance with Section 2.02 with respect to
those Notes, authenticate new Notes that reflect the amendment, supplement or waiver.

          Failure to make the appropriate notation or issue a new Note shall not affect the validity and
effect of such amendment, supplement or waiver.

Section 10.06. Trustee to Sign Amendments, etc.

          The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this
Article 10 if the amendment or supplement does not adversely affect the rights, duties, liabilities
or immunities of the Trustee. The Company may not sign an amendment or supplemental Indenture
until the Board of Directors approves it. In executing any amended or supplemental indenture, the
Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected
in relying upon, in addition to the documents required by Section 10.04 hereof, an Officer’s
Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental
indenture is authorized or permitted by this Indenture.

ARTICLE 11.

SATISFACTION AND DISCHARGE

Section 11.01. Satisfaction and Discharge.

          This Indenture will be discharged and will cease to be of further effect (except as set forth
below) and the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture when:

     (1) either:

     (a) all the Notes theretofore authenticated and delivered (except lost, stolen
or destroyed notes which have been replaced or paid as provided in Section 2.07 and
Notes for whose payment money has theretofore been deposited in trust or segregated
and held in trust by the Company and thereafter repaid to the Company or discharged
from such trust) have been delivered to the Trustee for cancellation; or

     (b) all Notes not theretofore delivered to the Trustee for cancellation (1)
have become due and payable or (2) will become due and payable within one year, or
are

-72-

 

to be called for redemption within one year, under arrangements reasonably
satisfactory to the Trustee for the giving of notice of redemption by the Trustee in
the name, and at the expense, of the Company, and the Company has irrevocably
deposited or caused to be deposited with the Trustee funds in an amount sufficient
to pay and discharge the entire Indebtedness on the Notes not theretofore delivered
to the Trustee for cancellation, for principal of, and premium, if any, and interest
on, the Notes to the date of deposit together with irrevocable instructions from the
Company directing the Trustee to apply such funds to the payment thereof at maturity
or redemption, as the case may be;

     (2) the Company has paid all other sums payable under this Indenture by the Company;
and

     (3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel stating that all conditions precedent under this Indenture relating to the
satisfaction and discharge of this Indenture have been complied with.

          Notwithstanding the satisfaction and discharge of this Indenture, the Company’s obligations in
Sections 2.03, 2.04, 2.06, 2.07, 2.11, 7.07, 7.08, 12.02, 12.03 and 12.04, and the Trustee’s and
Paying Agent’s obligations in Section 11.02 shall survive until the Notes are no longer
outstanding. Thereafter, only the Company’s obligations in Section 7.07 shall survive.

Section 11.02. Application of Trust.

          All money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and, at
the written direction of the Company, be invested prior to maturity in U.S. Government Securities,
and applied by the Trustee in accordance with the provisions of the Notes and this Indenture, to
the payment, either directly or through any Paying Agent as the Trustee may determine, to the
persons entitled thereto, of the principal (and premium, if any) and interest for the payment of
which money has been deposited with the Trustee; but such money need not be segregated from other
funds except to the extent required by law.

ARTICLE 12.

MISCELLANEOUS

Section 12.01. Trust Indenture Act Controls.

          If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by
TIA § 318(c), the imposed duties shall control.

Section 12.02. Notices.

          Any notice or communication by the Company or the Trustee to the others is duly given if in
writing and delivered in person or mailed by first class mail (registered or certified, return
receipt requested), telex, telecopier or overnight air courier guaranteeing next-day delivery, to
the others’ address.

Attention: Corporate Trust Administration

          The Company or the Trustee, by notice to the others may designate additional or different
addresses for subsequent notices or communications.

          All notices and communications (other than those sent to Holders) shall be deemed to have been
duly given: at the time delivered by hand, if personally delivered; five Business Days after being
deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt
acknowledged, if telecopied; and the next Business Day after timely delivery to the courier, if
sent by overnight air courier guaranteeing next day delivery.

          Any notice or communication to a Holder shall be mailed by first class mail, certified or
registered, return receipt requested, or by overnight air courier guaranteeing next day delivery to
its address shown on the register kept by the Registrar. Any notice or communication shall also be
so mailed to any person described in TIA § 313(c), to the extent required by the TIA. Failure to
mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency
with respect to other Holders.

          Except for a notice to the Trustee, which is deemed given only when received, and except as
otherwise provided in this Indenture, if a notice or communication is mailed in the manner provided
above within the time prescribed, it is duly given, whether or not the addressee receives it.

          If the Company mails a notice or communication to Holders, it shall mail a copy to the Trustee
and each Agent at the same time.

          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.

-74-

 

          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.

Section 12.03. Communication by Holders of Notes with Other Holders of
Notes.

          Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their
rights under this Indenture or the Notes. The Company, the Trustee, the Registrar and anyone else
shall have the protection of TIA § 312(c).

Section 12.04. Certificate and Opinion as to Conditions Precedent.

          Upon any request or application by the Company to the Trustee to take any action under this
Indenture, the Company shall furnish to the Trustee:

     (a) an Officers’ Certificate in form and substance reasonably satisfactory to the
Trustee (which shall include the statements set forth in Section 12.05 hereof) stating that,
in the opinion of the signers, all conditions precedent and covenants, if any, provided for
in this Indenture relating to the proposed action have been satisfied; and

     (b) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee
(which shall include the statements set forth in Section 12.05 hereof) stating that, in the
opinion of such counsel, all such conditions precedent and covenants have been satisfied.

Section 12.05. Statements Required in Certificate or Opinion.

          Each certificate or opinion with respect to compliance with a condition or covenant provided
for in this Indenture (other than a certificate provided pursuant to TIA § 314(a)(4)) shall comply
with the provisions of TIA § 314(e) and shall include:

     (a) a statement that the person making such certificate or opinion has read such
covenant or condition;

     (b) a brief statement as to the nature and scope of the examination or investigation
upon which the statements or opinions contained in such certificate or opinion are based;

     (c) a statement that, in the opinion of such person, he or she has made such
examination or investigation as is necessary to enable him to express an informed opinion as
to whether or not such covenant or condition has been satisfied; and

     (d) a statement as to whether or not, in the opinion of such person, such condition or
covenant has been satisfied.

Section 12.06. Rules by Trustee and Agents.

          The Trustee may make reasonable rules for action by or at a meeting of Holders. The Registrar
or Paying Agent may make reasonable rules and set reasonable requirements for its functions.

-75-

 

Section 12.07. No Personal Liability of Directors, Officers, Employees and
Stockholders.

          No recourse for the payment of the principal of, premium, if any, or interest or Liquidated
Damages, if any, on any of the Notes, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of the Company or of
any Guarantor contained in this Indenture or in any of the Notes, or because of the creation of any
Indebtedness represented thereby, shall be had against any incorporator or past, present or future
director, officer, employee, controlling person or stockholder of the Company or of any Guarantor.
Each Holder by accepting a Note waives and releases all such liability. The waiver and release are
part of the consideration for issuance of the Notes. Such waiver may not be effective to waive
liabilities under the federal securities laws and it is the view of the Commission that such a
waiver is against public policy.

Section 12.08. Governing Law.

          THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE
AND THE NOTES WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT
THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

Section 12.09. No Adverse Interpretation of Other Agreements.

          This Indenture may not be used to interpret any other indenture, loan or debt agreement of the
Company or its Subsidiaries or of any other person. Any such indenture, loan or debt agreement may
not be used to interpret this Indenture.

Section 12.10. Successors.

          All agreements of the Company in this Indenture and the Notes shall bind its successors. All
agreements of the Trustee in this Indenture shall bind its successors.

Section 12.11. Severability.

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

Section 12.12. Counterpart Originals.

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

Section 12.13. Table of Contents, Headings, etc.

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

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

          1. Interest. Grant Prideco, Inc., a Delaware corporation (the “Company”), promises
to pay interest on the principal amount of this Note at 6 1/8% per annum until maturity and shall
pay the Liquidated Damages, if any, payable pursuant to Section 4 of the Registration Rights
Agreement referred to below. The Company shall pay interest and Liquidated Damages, if any,
semi-annually on February 15 and August 15 of each year, or if any such day is not a Business Day,
on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes
shall accrue from the most recent date to which interest has been paid or, if no interest has been
paid, from and including July 27, 2005 2 ; provided, however, that if there is
no existing Default in the payment of interest, and if this Note is authenticated between a record
date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be February 15, 2006 3 . The Company shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal
and premium, if any, from time to time on demand at a rate that is 1% per annum in excess of the
then applicable interest rate

 

			
	2	 	With respect to Notes issued on the Issue
Date.
	 
	3	 	With respect to Notes issued on the Issue
Date.

A-4

 

on the Notes to the extent lawful; it shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue installments of interest and Liquidated
Damages, if any (without regard to any applicable grace periods) from time to time on demand at the
same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year of
twelve 30-day months.

          2. Method of Payment. The Company shall pay principal, premium, if any, interest and
Liquidated Damages, if any, on the Notes to the persons who are registered Holders of Notes at the
close of business on February 1 or August 1 next preceding the interest payment date, even if such
Notes are cancelled after such record date and on or before such interest payment date, except as
provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes shall be
payable by wire transfer of immediately available funds to the registered Holder of the relevant
Global Note and, with respect to certificated Notes, by wire transfer of immediately available
funds in accordance with instructions provided by the registered holders of certificated Notes or,
if no such instructions are specified, by mailing a check to each such Holder’s registered address.
Such payment shall be in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts.

          3. Paying Agent and Registrar. Initially, Wells Fargo Bank, N.A., the Trustee under
the Indenture, shall act as Paying Agent and Registrar. The Company may change any Paying Agent or
Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

          4. Indenture. The Company issued the Notes under an Indenture dated as of July 27,
2005 (“Indenture”) among the Company, the Trustee and the Guarantors identified therein. The terms
of the Notes include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S. C. §§ 77aaa-77bbbb), as amended. The Notes
are subject to all such terms, and Holders are referred to the Indenture and the TIA for a
statement of such terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The
Company may issue Additional Notes under the Indenture subject to compliance with Section 4.09
thereof, unlimited in aggregate principal amount.

          5. Optional Redemption. The Company may redeem any or all of the Notes at any time
on or after August 15, 2010, upon not less than 30 nor more than 60 days’ prior notice in amounts
of $1,000 or an integral multiple thereof at the redemption prices (expressed as a percentage of
the principal amount) set forth below, if redeemed during the 12-month period beginning August 15
of the years indicated below:

	 	 	 	 	 
	Year	 	Redemption Price
	2010
	 	 	103.063	%
	2011
	 	 	102.042	%
	2012
	 	 	101.021	%
	2013 and thereafter
	 	 	100.000	%

in each case together with accrued and unpaid interest and Liquidated Damages, if any, to the date
of redemption.

          If less than all the Notes are to be redeemed, the Trustee will select the particular Notes or
portions thereof to be redeemed or purchased among the Holders of the Notes in compliance with the
requirements of the principal national securities exchange, if any, on which the Notes are listed
or, if the

A-5

 

Notes are not so listed, on a pro rata basis, by lot or in accordance with any other method
the Trustee considers fair and appropriate subject to certain restrictions contained in the
Indenture.

          6. Optional Redemption Upon Equity Offering. From time to time, on or prior to
August 15, 2008, the Company may, at its option, use the net cash proceeds of one or more Equity
Offerings to redeem up to 35% of the aggregate principal amount of the Notes issued under the
Indenture at a redemption price equal to 106.125% of the principal amount thereof, plus accrued and
unpaid interest thereon, if any, and Liquidated Damages, if any, to the date of redemption;
provided that (a) at least 65% of the original principal amount of Notes issued under the Indenture
shall remain outstanding immediately after any such redemption, and (b) the Company shall make such
redemption not more than 90 days after the consummation of any such Equity Offering. If a partial
redemption is made with the proceeds of an Equity Offering, selection of the Notes or portions
thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro
rata basis as is practicable (subject to the procedures of the Depository), unless such method is
prohibited.

          As used in the preceding paragraph, “Equity Offering” means any public or private sale of the
Company’s Equity Interests (other than Disqualified Stock.)

          7. Mandatory Redemption. Except as set forth in paragraph 8 below, the Company shall
not be required to make mandatory redemption payments with respect to the Notes.

          8. Repurchase at Option of Holder.

          (a) Upon the occurrence of a Change of Control Triggering Event, each Holder shall have the
right to require the Company to make an offer (a “Change of Control Offer”) to each Holder to
repurchase all or any part, equal to $1,000 or an integral multiple of $1,000, of the Holder’s
Notes at an offer price in cash equal to 101% of the aggregate principal amount of Notes
repurchased, plus accrued and unpaid interest and Liquidated Damages, if any, on Notes repurchased
to the date fixed for repurchase (the “Change of Control Payment”).

          (b) If the Company or a Restricted Subsidiary consummates any Asset Sales, when the aggregate
amount of Excess Proceeds exceeds $20.0 million, the Company shall make a pro rata offer to
purchase (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that
is pari passu with the Notes containing provisions similar to those set forth in the Indenture with
respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the
maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out
of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal
amount plus accrued and unpaid interest to the date of purchase, and will be payable in cash. If
any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those
Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate
principal amount of Notes and other pari passu Indebtedness tendered in such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other pari passu
Indebtedness to be purchased on a pro rata basis (based upon the aggregate principal amount of the
Notes and such other pari passu Indebtedness tendered). Upon completion of each Asset Sale Offer,
the amount of Excess Proceeds will be deemed to have been reset at zero.

          9. Notice of Redemption. Notice of redemption shall be mailed at least 30 days but
not more than 60 days before any optional redemption date to each Holder whose Notes are to be
redeemed at its registered address. Notes and portions of Notes selected shall be in amounts of
$1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be
redeemed, the entire out-

A-6

 

standing amount of Notes held by such Holder, even if not a multiple of $1,000, shall be
redeemed. On and after the redemption date interest ceases to accrue on Notes, or portions thereof
called for redemption.

          10. Denominations, Transfer, Exchange. The Notes are in registered form without
coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Notes may be
registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee
may require a Holder, among other things, to furnish appropriate endorsements and transfer
documents and the Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Registrar shall not be required to register the transfer of or
exchange any Note selected for redemption in whole or in part except the unredeemed portion of any
Note being redeemed in part. The Company shall not be required (i) to issue, to register the
transfer of or to exchange any Notes during a period beginning at the opening of business 15 days
before the day of any selection of Notes for redemption under Section 3.02 of the Indenture and
ending at the close of business on the day of selection; (ii) to register the transfer of or to
exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of
any Note being redeemed in part; or (iii) to register the transfer of or to exchange a Note between
a record date and the next succeeding interest payment date.

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

          12. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture
or the Notes may be amended or supplemented with the consent of the Holders of at least a majority
in principal amount of the then outstanding Notes voting as a single class, and any existing
default or compliance with any provision of the Indenture or the Notes may be waived with the
consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a
single class. Without the consent of any Holder of a Note, the Indenture or the Notes may be
amended or supplemented to cure any ambiguity, defect or inconsistency; to provide for
uncertificated Notes in addition to or in place of certificated Notes; to provide for the
assumption of the Company’s obligations to Holders of the Notes in case of a merger or
consolidation, or sale of substantially all of the Company’s assets; to make any change that would
provide any additional rights or benefits to the Holders of the Notes or that does not adversely
affect the legal rights under the Indenture of any such Holder; or to comply with the requirements
of the Commission in order to effect or maintain the qualification of the Indenture under the TIA.

          13. Defaults and Remedies. Events of Default include, in summary form: (a) default
in the payment when due of principal of or premium, if any, on any Note when the same becomes due
and payable at maturity, upon acceleration, redemption or otherwise; (b) default in the payment
when due of interest on, or Liquidated Damages with respect to, any Note, and such default
continues for a period of 30 days; (c) default in the performance or breach of the provisions by
the Company or any of its Restricted Subsidiaries of Sections 4.07, 4.09 or 5.01 of the Indenture;
(d) default in the performance by the Company or any of its Restricted Subsidiaries of Sections
4.15 or 4.16 of the Indenture, and such default continues for a period of 30 days after written
notice; (e) default in the performance of or breaches of any other covenant or agreement of the
Company under the Indenture or under the Notes (other than a default specified in clause (a), (b),
(c) or (d) above) by the Company or any of its Restricted Subsidiaries and such default or breach
continues for a period of 60 days after written notice by the Trustee to the Company or by the
Holders of 25% or more in aggregate principal amount of the Notes to the Company and the Trustee;
(f) certain defaults under any mortgage, indenture or instrument under which there may be issued or
by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or
any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of
its Restricted Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after
the date of the Indenture; (g) default by the Company or any of its Subsidiaries in the payment of
final judgments aggregating in excess of $10.0 million, which judgments are not paid, discharged

A-7

 

or stayed for a period of 60 days; (h) except as permitted by the Indenture, any Subsidiary
Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease
for any reason to be in full force and effect or any Guarantor, or any person acting on behalf of
any Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee; and (i)
certain events of bankruptcy or insolvency with respect to the Company or any of its Restricted
Subsidiaries. If any Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and
payable, subject to certain conditions. Notwithstanding the foregoing, in the case of an Event of
Default arising from certain events of bankruptcy or insolvency, all outstanding Notes shall become
due and payable without further action or notice. Holders may not enforce the Indenture or the
Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority
in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise
of any trust or power. Except in the case of a Default or Event of Default in payment of
principal of, premium, if any, or interest on any Note, the Trustee may withhold from Holders of
the Notes notice of any continuing Default or Event of Default if and so long as a committee of its
Responsible Officers in good faith determines that withholding the notice is in the interests of
the Holders of the Notes. At any time after declaration of acceleration, but before a judgment or
decree for the payment of the money due has been obtained by the Trustee, the Holders of at least a
majority in principal amount of the outstanding Notes by written notice to the Company and to the
Trustee may waive all past Defaults, except a Default in the payment of principal of, premium,, if
any, or interest on any Note or in respect of a covenant or provision of the Indenture which cannot
be modified or amended without the consent of the Holder of each outstanding Note affected. The
Company is required to deliver to the Trustee annually a statement regarding compliance with the
Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

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

          15. No Recourse Against Others. No recourse for the payment of the principal of,
premium, if any, or interest or Liquidated Damages, if any, on any of the Notes, or for any claim
based thereon or otherwise in respect thereof, and no recourse under or upon any obligation,
covenant or agreement of the Company contained in the Indenture or in any of the Notes, or because
of the creation of any Indebtedness represented thereby, shall be had against any incorporator or
past, present or future director, officer, employee, controlling person or stockholder of the
Company or of any Guarantor. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance of the Notes.

          16. Authentication. This Note shall not be valid until authenticated by the manual
signature of the Trustee or an authenticating agent in accordance with the Indenture.

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

          18. Additional Rights of Holders of Restricted Global Notes and Restricted Definitive
Notes. In addition to the rights provided to Holders of Notes under the Indenture, Holders of
Restricted Global Notes and Restricted Definitive Notes shall have all the rights set forth in the
Registration Rights Agreement dated as of July 27, 2005, between the parties named on the signature

A-8

 

pages thereof, as such agreement may be amended, modified or supplemented from time to time
(the “Registration Rights Agreement”).

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

          The Company shall furnish to any Holder upon written request and without charge a copy of the
Indenture and/or the Registration Rights Agreement. Requests may be made to:

Capitalized terms used but not defined herein shall have the meanings given to them in the
Indenture.

                                                   (the “Transferor”) owns and proposes to transfer the Note[s] or interest in
such Note[s] specified in Annex A hereto, in the principal amount of $                      in such Note[s]
or interests (the “Transfer”), to                      (the “Transferee”), as further specified in Annex A
hereto. In connection with the Transfer, the Transferor hereby certifies that:

[CHECK ALL THAT APPLY]

and, accordingly, the Transferor hereby further certifies that the beneficial interest or
Definitive Note is being transferred to a person that the Transferor reasonably believed and
believes is purchasing the beneficial interest or Definitive Note for its own account, or for one

to and in accordance with Rule 904 under the Securities Act and, accordingly, the Transferor hereby
further certifies that (i) the Transfer is not being made to a person in the United States and (x)
at the time the buy order was originated, the Transferee was outside the United States or such

Company will bear a legend to the foregoing effect.

     4. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or
