similar import refer to this Indenture as a whole and not to any particular Article, Section

ARTICLE 2

THE NOTES

     Section 2.01. Form and Dating.

          Provisions relating to the Notes are set forth in the Rule 144A/Regulation S Appendix attached
hereto (the “Appendix”), which is hereby incorporated in and expressly made part of this
Indenture. The Notes and the Trustee’s certificate of authentication therefor shall be
substantially in the form of Exhibit A to this Indenture, which is hereby incorporated in and
expressly made a part of this Indenture. The Notes may have notations, legends or endorsements
required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage
(provided that any such notation, legend or endorsement is in a form acceptable to the Company).
Each Note shall be dated the date of its authentication. The terms of the Notes set forth in
Exhibit A are part of the terms of this Indenture.

     Section 2.02. Execution and Authentication.

          The Notes shall be executed by an Officer or any authorized signatory as identified in an
Officers’ Certificate (pursuant to a power of attorney or other similar instrument). The signature
of any such Officer (or authorized signatory) on the Notes shall be by manual or facsimile
signature in the name and on behalf of the Company.

          If any Officer whose signature is on a Note no longer holds that office at the time the
Trustee or authenticating agent authenticates the Note, the Note shall be valid nevertheless.

          A Note shall not be valid until the Trustee or authenticating agent manually signs the
certificate of authentication on the Note. The signature shall be conclusive evidence that the
Note has been authenticated under this Indenture. The Notes shall be dated the date of their
authentication.

          On the Issue Date, the Trustee shall authenticate and deliver $200.0 million of Initial Notes
and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver
Additional Notes for original issue, in each case upon the conditions and subject to the
requirements provided in Section 2.2 of the Appendix.

- 27 -

 

          The Trustee may appoint an authenticating agent (the “Authenticating Agent”)
reasonably acceptable to the Company to authenticate Notes. Unless otherwise provided in the
appointment, an Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each
reference in this Indenture to authentication by the Trustee includes authentication by such
Authenticating Agent. An Authenticating Agent has the same rights as an Agent to deal with the
Company or with any Affiliate of the Company.

          The Notes will be issued in registered form, without coupons, and in denominations of $1,000
and integral multiples of $1,000.

     Section 2.03. Registrar and Paying Agent.

          The Company shall maintain an office or agency where Notes may be presented for registration
of transfer or for exchange (“Registrar”) and an office or agency where Notes may be
presented for payment (“Paying Agent”); provided that payment of interest may, at
the option of the Company, be made by check mailed to a Holder at his registered address. The
Registrar shall keep the Register of the Notes and of their transfer and exchange. The Company may
appoint one or more co-registrars and one or more co-paying agents. The term “Registrar” includes
any co-registrar, and the term “Paying Agent” includes any additional paying agent.

          The Company shall enter into an appropriate agency agreement with any Agent not a party to
this Indenture. The agreement shall implement the provisions of this Indenture that relate to such
Agent. The Company may change any Registrar or Paying Agent without notice to the Holders.

          The Company shall notify the Trustee in writing of the name and address of any Agent not a
party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar
or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as
Paying Agent or Registrar.

          The Company initially appoints the Trustee at the Corporate Trust Office to act as Paying
Agent and Registrar.

     Section 2.04. Paying Agent To Hold Money in Trust.

          Each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money
held by such Paying Agent for the payment of principal, premium, if any, or interest on the Notes,
and shall notify the Trustee in writing of any default by the Company or any Guarantor in making
any such payment. While any such default continues, the Trustee may require a Paying Agent to pay
to the Trustee all money held by it upon demand. The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee or to account for any funds disbursed. Upon
payment over to the Trustee and accounting for any funds disbursed, such Paying Agent shall have no
further liability for the money. If the Company, a Subsidiary or another Related Person or any of
them acts as Paying Agent, it shall segregate and hold as a separate trust fund for the benefit of
the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes.

- 28 -

 

     Section 2.05. Noteholder Lists.

          The Trustee shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of Holders (the “Register”) and shall
otherwise comply with TIA. If the Trustee is not the Registrar, the Company shall furnish to the
Trustee on or before each interest payment date and at such other times as the Trustee may
reasonably request in writing a list, in such form and as of such date as the Trustee may require,
of the names, addresses and tax identification numbers of Holders, and the Company shall otherwise
comply with TIA Section 312(a).

     Section 2.06. Transfer and Exchange.

          A Holder will be able to register the transfer of or exchange Notes only in accordance with
the provisions of this Indenture. Where Notes are presented to the Registrar with a request to
register the transfer or to exchange them for an equal principal amount of Notes of other
authorized denominations, the Registrar shall register the transfer or make the exchange if the
requirements of Section 8-401(a) of the New York Uniform Commercial Code as then in effect are met.
To permit registrations of transfer and exchanges, the Trustee shall authenticate Notes at the
Registrar’s written (if the Registrar is not the Trustee) request. The Registrar may require a
Holder, among other things, to furnish appropriate endorsements and transfer documents (each in a
form satisfactory to the Company and the Registrar) and to pay any taxes or other governmental
charges required by law or permitted by this Indenture. Without the prior consent of the Company,
the Registrar is not required (1) to register the transfer of or exchange any Note selected for
redemption, (2) to register the transfer of or exchange any Note for a period of 15 days before a
selection of Notes to be redeemed or (3) to register the transfer or exchange of a Note between a
record date and the next succeeding interest payment date.

          No Holder shall Incur a service charge for any registration of transfer or exchange of Notes,
but the Company or the Trustee, as appropriate, may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection with any transfer,
registration of transfer or exchange of Notes, other than exchanges pursuant to Section 2.10, 3.06,
4.08, 4.15 or 9.05 not involving any transfer.

     Section 2.07. Replacement Notes.

          If the Holder of a Note claims that the Note has been mutilated, lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the
requirements of Section 8-405 of the New York Uniform Commercial Code are met and, in the case of a
mutilated Note, such mutilated Note is surrendered to the Trustee. If required by the Trustee or
the Company, an indemnity bond must be supplied by the Holder that is sufficient, in the judgment
of both, to protect the Company, each Guarantor, the Trustee, or any Agent from any loss which any
of them may suffer if a Note is replaced. The Company and the Trustee may charge for their
expenses in replacing a Note.

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

- 29 -

 

          Every replacement Note is an Obligation of the Company. The provisions of this Section 2.07
are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect
to the replacement of mutilated, destroyed, lost or stolen Notes.

     Section 2.08. Outstanding Notes.

          Notes outstanding at any time are all the Notes authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation and those described in this Section as not
outstanding. Except as set forth in Section 2.09, a Note does not cease to be outstanding because
the Company or one of its Subsidiaries or Related Persons holds the Note.

          If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee
receives proof satisfactory to it, or a court holds, that the replaced Note is held by a
bona fide purchaser. 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.

          If the Paying Agent (other than the Company) holds by 11:00 A.M. New York time on a redemption
date, repurchase date or other 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 interest on
them shall cease to accrue.

     Section 2.09. Notes Held by the Company or a Related Person.

          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 a Subsidiary or a Related Person
shall be disregarded, except that for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Notes which the Trustee
actually knows are so owned shall be so disregarded.

     Section 2.10. Temporary Notes.

          Until definitive Notes are ready for delivery, the Company may prepare and the Trustee 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. Without
unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes
in exchange for temporary Notes.

     Section 2.11. Cancellation.

          The Company or any Guarantor 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, exchange or payment. The Trustee shall cancel all Notes surrendered for
registration of transfer, exchange, payment or cancellation and shall dispose of such canceled
Notes in its customary manner. The Company may not issue new Notes to replace Notes that it has
paid or delivered to the Trustee for cancellation.

- 30 -

 

     Section 2.12. Defaulted Interest.

          If and to the extent 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 not prohibited by applicable
statute or case law, interest at the rate then borne by the Notes on the defaulted interest. It
shall pay the defaulted interest to the Persons who are Holders on a subsequent special record
date. The Company or Trustee (at the direction of the Company) shall fix such record date and
payment date. At least 15 days before the special record date, the Company or Trustee (at the
direction of the Company, provided that the Trustee shall have received the same at least
10 but not more than 30 days prior thereto or such shorter period prior thereto as is acceptable to
the Trustee) shall mail to Holders a notice that states the record date, payment date and amount of
interest to be paid.

     Section 2.13. Persons Deemed Owners.

          Prior to due presentment of a Note for registration of transfer, the Company, the Guarantors,
the Trustee and any agent of the Company, the Guarantors or the Trustee may conclusively presume
and shall treat the Person in whose name such Note is registered as the owner of such Note for the
purpose of receiving payment of principal, premium, if any, and (subject to Section 2.12) interest
on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and
neither the Company, the Guarantors, the Trustee nor any agent of the Company, the Guarantors or
the Trustee shall be affected by notice to the contrary. None of the Company, the Guarantors, the
Trustee, any Paying Agent or the Registrar will have any responsibility or liability for any aspect
of the records relating to or payments made on account of or actions taken in respect of beneficial
ownership interests of a Note in global form or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests (including but not limited to CUSIP, ISIN
or Common Code numbers, if any).

     Section 2.14. Computation of Interest.

          Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day
months.

     Section 2.15. CUSIP Numbers, Etc.

          The Company, in issuing the Notes, may use CUSIP, ISIN and Common Code numbers (if then
generally in use), and, if so, the Trustee shall use the CUSIP, ISIN and Common Code numbers for
purposes of the identification of the Notes in notices as a convenience to Holders;
provided that any such notice may state that no representation is made by the Trustee 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 shall promptly notify the Trustee of any change in CUSIP, ISIN and Common Code numbers.

- 31 -

 

     Section 2.16. Issuance of Additional Notes.

          The Company shall be entitled to issue an unlimited aggregate principal amount of Additional
Notes under this Indenture, all of which shall have identical terms as the Notes issued on the
Issue Date, other than with respect to the date of issuance, issue price, and amount of interest
payable on the first payment date applicable thereto (and, if such Additional Notes shall be issued
in the form of Exchange Notes, other than with respect to transfer restrictions); provided
that such issuance is not prohibited by Section 4.10. The Initial Notes issued on the Issue Date,
any Additional Notes and all Exchange Notes or Private Exchange Notes issued in exchange therefor
shall be treated as a single class for all purposes under this Indenture.

          With respect to any Additional Notes, the Company shall set forth in an Officers’ Certificate,
which shall be delivered to the Trustee, the following information:

     (1) the aggregate principal amount of such Additional Notes to be authenticated and
delivered pursuant to this Indenture;

     (2) the issue price, the issue date and the CUSIP number and any corresponding ISIN or
Common Code number of such Additional Notes and the amount of interest payable on the first
payment date applicable thereto; provided, however, that no Additional Notes
may be issued at a price that would cause such Additional Notes to have “original issue
discount” within the meaning of Section 1273 of the Internal Revenue Code of 1986, as
amended; and

     (3) whether or not such Additional Notes shall be Transfer Restricted Securities.

ARTICLE 3

REDEMPTION

     Section 3.01. Notices to Trustee.

          If the Company wants to redeem all or a portion of the Notes pursuant to paragraph 6 of the
Notes, it shall provide written notice to the Trustee at least five Business Days (unless a shorter
notice period shall be satisfactory to the Trustee) before the date of giving notice of the
redemption specifying the proposed redemption date, the principal amount of Notes to be redeemed
and whether or not it requests the Trustee to give notice of such redemption.

     Section 3.02. Selection of Notes To Be Redeemed.

          In the event that less than all of the Notes are to be redeemed at any time pursuant to an
optional redemption, selection of the Notes for redemption will be made by the Trustee 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 then listed on a national security exchange, on a
pro rata basis, by lot or by such method as the Trustee shall deem fair and
appropriate; provided, however, that no Notes of a principal amount of $1,000 or
less shall be redeemed in part. In addition, if partial redemption is made pursuant to the
provisions described under paragraph 6(b) of

- 32 -

 

the Notes, 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 that method is otherwise
prohibited.

     Section 3.03. Notice of Redemption.

          At least 30 days but not more than 60 days before a redemption date, the Company shall mail by
first-class mail a notice of redemption to each Holder whose Notes are to be redeemed at its
registered address except that a redemption notice may be given more than 60 days prior to a
redemption date in connection with a defeasance of the Notes or a satisfaction and discharge of
this Indenture in accordance with Article 8 hereof.

          The notice shall identify the Notes and the principal amount thereof to be redeemed (including
the applicable CUSIP, ISIN and Common Code numbers, if any) and shall state:

     (1) the redemption date;

     (2) the redemption price (plus the amount of accrued and unpaid interest to be paid on
each $1,000 principal amount of the Notes called for redemption) or, if the redemption price
is not then determinable, the manner in which it will be determined;

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

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

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

     (6) in the case of Notes to be redeemed in part, the portion of the principal amount of
the Note to be redeemed.

          If any of the Notes to be redeemed is in the form of a Global Note, then the Company shall
modify such notice to the extent necessary to accord with the procedures of the Depository
applicable to redemptions.

          At the Company’s written direction to the Trustee given in accordance with Section 3.01
hereof, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s
expense. In such event the Company shall provide the Trustee with the information required by
clauses (1) through (6) in its written notice to the Trustee.

     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 become irrevocably due and payable on the redemption date at the redemption price,
together with interest accrued and unpaid thereon to the redemption
date (sub-

- 33 -

 

ject to the right of Holders of record on the relevant record date to receive interest due on
the relevant interest payment date). Upon surrender to the Paying Agent such Notes shall be paid
at the redemption price, together with interest accrued and unpaid thereon as aforesaid. Failure
to give notice or any defect in the notice to any Holder shall not affect the validity of the
notice to any other Holder. A notice of redemption may not be conditional.

     Section 3.05. Deposit of Redemption Price.

          On or before 11:00 A.M. New York time on the redemption date, the Company shall deposit with
the Paying Agent (or, if the Company, a Subsidiary or another Related Person is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 2.04 hereof) money in immediately
available funds sufficient to pay the redemption price of and accrued and unpaid interest on all
Notes to be redeemed on the redemption date. The Trustee or the Paying Agent shall promptly return
to the Company any money not required for that purpose less the expenses of the Trustee as provided
herein. On and after the date of redemption, interest will cease to accrue on Notes or portions
thereof called for redemption so long as the Company has deposited with the Paying Agent funds in
satisfaction of the redemption price (together with accrued and unpaid interest on the Notes to be
redeemed) pursuant to this Indenture. If a Note is redeemed on or after a 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 cancellation of a Note that is redeemed in part, the Company shall issue in the name of
the Holder and the Trustee shall authenticate a new Note equal in principal amount to the
unredeemed portion of the Note surrendered.

Indenture may be served. The Company shall give prompt written notice to the Trustee of the

prompt written notice to the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.

benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this Indenture; and each
of the Company and the Guarantors (to the extent that it may lawfully do so) hereby expressly
waives all benefit or advantage of any such law, and covenants that it will not, by resort to any
such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law had been enacted.

     Section 4.06. Corporate Existence.

          Subject to Article 5 of this Indenture, the Company shall do or cause to be done all things

existence of each of its Restricted Subsidiaries in accordance with their respective organizational
documents (as the same may be amended from time to time) and 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 existence of any Restricted Subsidiary, if (i) such preservation or
existence is not material to the conduct of business of the Company and its Restricted Subsidiaries
taken as a whole, and (ii) the loss of such right, license or franchise or the dissolution of such
Restricted Subsidiary does not have a material adverse impact on the Holders.

     Section 4.07. Notice of Default.

          In the event that any Default under Section 6.01 hereof shall occur, the Company shall give
prompt written notice of such Default to the Trustee specifying such Default and what action the

     Section 4.08. Change of Control.

          (a) Upon the occurrence of any Change of Control, each Holder will have the right to require
that the Company purchase that Holder’s Notes for a cash price (the “Change of Control Purchase
Price”) equal to 101% of the principal amount of the Notes to be purchased, plus accrued and
unpaid interest thereon, if any, to the date of purchase;

          (b) Within 30 days following any Change of Control, the Company will mail, or caused to be
mailed, to the Holders a notice:

     (1) describing the transaction or transactions that constitute the Change of Control;

     (2) offering to purchase, pursuant to the procedures required by this Indenture and

the date the notice is mailed) and for the Change of Control Purchase Price, all Notes
properly tendered by such Holder pursuant to such Change of Control Offer; and

     (3) describing the procedures that Holders must follow to accept, or withdraw the
Holder’s previous acceptance of, the Change of Control Offer.

lawful, (1) accept for payment all Notes or portions thereof validly tendered and not properly
withdrawn pursuant to the Change of Control Offer, (2) deposit by 11:00 A.M., New York City time,
on such date with the Paying Agent an amount equal to the Change of Control Purchase Price in
respect of all Notes or portions thereof so validly tendered and not properly withdrawn and (3)
deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers
Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by
the Company. The Paying Agent shall promptly (but in any case not later than five days after the
expiration date for the Change of Control) mail or deliver to each Holder of Notes so validly
tendered and not properly withdrawn the Change of Control Purchase Price for such Notes.

          (d) Upon surrender and cancellation of a Certificated Note that is purchased in part pursuant
to the Change of Control Offer, the Company shall promptly issue and the Trustee shall authenticate
and mail (or cause to be transferred by book entry) to the surrendering Holder of such Certificated
Note, a new Certificated Note equal in principal amount to the unpurchased portion of such
surrendered Certificated Note; provided that each such new Certificated Note shall be in a

          Upon surrender of a Global Note that is purchased in part pursuant to a Change of Control
Offer, the Paying Agent shall forward such Global Note to the Notes Custodian who shall make a
notation in its records so as to reduce the principal amount of such Global Note to an amount equal
to the unpurchased portion of such Global Note, as provided in Section 2.01

hereof and the Appendix. For purposes of this Section 4.08 the Trustee shall act as the
Paying Agent.

          The Company shall publicly announce the results of the Change of Control Offer on or as soon
as practicable after the date of purchase.

          (e) The Company’s obligation to make a Change of Control Offer will be satisfied if a third
party makes the Change of Control Offer in the manner and at the times and otherwise in compliance
in all material respects with the requirements applicable to a Change of Control Offer made by the
Company and purchases all Notes properly tendered and not withdrawn under the Change of Control
Offer.

          (f) The Company shall comply with applicable tender offer rules, including the requirements
of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection
with the purchase of Notes pursuant to a Change of Control Offer. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of this Section 4.08,

to have breached its obligations under this Section 4.08 by virtue of such compliance.

     (4) Indebtedness under Hedging Obligations; provided that such Hedging
Obligations are incurred by the Company or any Restricted Subsidiary in the ordinary course
of business and not for the purpose of speculation.

     (5) Indebtedness of the Company owed to a Restricted Subsidiary and Indebtedness of any
Restricted Subsidiary owed to the Company or any other Restricted Subsidiary;
provided, however, that upon any such Restricted Subsidiary ceasing to be a
Restricted Subsidiary or such Indebtedness being owed to any Person other than the Company
or a Restricted Subsidiary, the Company or such Restricted Subsidiary, as applicable, shall
be deemed to have incurred Indebtedness not permitted by this clause (5);

     (6) Indebtedness in respect of bid, performance or surety bonds issued for the account
of the Company or any Restricted Subsidiary in the ordinary course of business, including
guarantees or obligations of the Company or any Restricted Subsidiary with respect to
letters of credit supporting such bid, performance or surety obligations (in each case other
than for an obligation for money borrowed);

     (7) Purchase Money Indebtedness incurred by the Company or any Restricted Subsidiary,
and Refinancing Indebtedness thereof, in an aggregate amount not to exceed at any time
outstanding the greater of (a) $40.0 million and (b) 15% of the net book value of the
aircraft owned by the Company and the Restricted Subsidiaries;

     (8) Indebtedness arising from the honoring by a bank or other financial institution of
a check, draft or similar instrument inadvertently (except in the case of daylight
overdrafts) drawn against insufficient funds in the ordinary course of business;
provided, however, that such Indebtedness is extinguished within five
Business Days of incurrence;

     (9) Indebtedness arising in connection with endorsement of instruments for deposit in

not to exceed $25.0 million at any time outstanding.

          For purposes of determining compliance with this covenant, in the event that an item of
Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness
described in clauses (1) through (11) above or is entitled to be incurred pursuant to the Coverage
Ratio Exception, the Company shall, in its sole discretion, classify or later reclassify such item
of Indebtedness and may divide and classify or later reclassify such Indebtedness in more than one
of the types of Indebtedness described, except that Indebtedness incurred under the Credit

“Restricted Payments Basket”) of (without duplication):

     (A) 50% of Consolidated Net Income for the period (taken as one accounting
period) commencing on July 1, 2002 to and including the last day of the fiscal

lesser of (i) the return of capital with respect to such Investment and (ii) the
amount of such Investment that was treated as a Restricted Payment, in either case,
less the cost of the disposition of such Investment and net of taxes, plus

     (E) upon a Redesignation of an Unrestricted Subsidiary as a Restricted

Indenture (including, without limitation, the Credit Agreement) as in effect on that date;

     (5) restrictions on the transfer of assets subject to any Lien permitted under this
Indenture imposed by the holder of such Lien;

     (6) any restriction with respect to a Restricted Subsidiary (or any of its assets)

     (7) any instrument governing Acquired Indebtedness, which encumbrance or restriction is
not applicable to any Person, or the assets of any Person, other than the Person or the
assets of the Person so acquired;

     (8) any other agreement governing Indebtedness entered into after the Issue Date that
contains encumbrances and restrictions taken as a whole that are not materially more

     (12) any encumbrances or restrictions imposed by any amendments or refinancings of the

Company’s Board of Directors, no more materially restrictive with respect to such
encumbrances and restrictions than those prior to such amendments or refinancings; and

     (13) restrictions on cash or other deposits or net worth imposed by customers under
contracts entered into in the ordinary course of business.

 - 43 -

 

     Section 4.13. Limitations on Liens.

          The Company shall not, and shall not permit any Restricted Subsidiary to, directly or
indirectly, create, incur, assume or permit or suffer to exist any Lien of any nature whatsoever
against (other than Permitted Liens) any assets of the Company or any Guarantor (including Equity
Interests of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, or
any proceeds therefrom, or assign or otherwise convey any right to receive income or profits
therefrom, unless contemporaneously therewith:

     (1) in the case of any Lien securing an obligation that ranks pari passu with the Notes
or a Note Guarantee, effective provision is made to secure the Notes or such Note Guarantee,
as the case may be, at least equally and ratably with or prior to such obligation with a
Lien on the same collateral; and

     (2) in the case of any Lien securing an obligation that is subordinated in right of

agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (an
“Affiliate Transaction”), unless:

     (1) such 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 at such time on an arm’s-length basis by the Company or that Restricted
Subsidiary from a Person that is not an Affiliate of the Company or that Restricted
Subsidiary; and

     (2) the Company delivers to the Trustee:

     (A) with respect to any Affiliate Transaction involving aggregate value in

Transaction complies with clause (1) above and a Secretary’s Certificate which sets
forth and authenticates a resolution that has been adopted by the Independent

 - 44 -

 

          (b) The foregoing restrictions shall not apply to:

     (1) transactions exclusively between or among (A) the Company and one or more

return or with which the Company or such Subsidiaries are part of a consolidated group for
tax purposes, on the other hand, which payments by the Company and the Restricted
Subsidiaries are not in excess of the tax liabilities that would have been payable by them
on a stand-alone basis;

     (4) loans and advances permitted by clause (3) of the definition of “Permitted
Investments”;

     (5) Restricted Payments which are made in accordance with Section 4.11 of this
Indenture; or

     (6) any transaction with an Affiliate where the only consideration paid by the Company
or any Restricted Subsidiary is Qualified Equity Interests.

     Section 4.15. Limitations on Asset Sales.

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

(1) the Company or such Restricted Subsidiary receives consideration at the time of such
Asset Sale at least equal to the Fair Market Value of the assets included in such Asset
Sale; and

(2) at least 75% of the total consideration received in such Asset Sale consists of cash or
Cash Equivalents.

For purposes of clause (2), the following shall be deemed to be cash:

     (A) the amount (without duplication) of any Indebtedness or other liabilities, as shown
on Company’s most recent consolidated balance sheet, of the Company or any Restricted
Subsidiary (other than contingent liabilities and liabilities that are by their terms
subordinated to the Notes or any Note Guarantee) that are assumed by the transferee in such
Asset Sale pursuant to a customary novation agreement that releases the Company or such
Restricted Subsidiary from further liability;

 - 45 -

 

     (B) the amount of any obligations received from such transferee that are within 90 days
converted by the Company or such Restricted Subsidiary to cash (to the extent of the cash
actually so received), and

     (C) the Fair Market Value of any assets (other than securities) received by the Company
or any Restricted Subsidiary to be used by it in a Permitted Business.

          If at any time any non-cash consideration received by the Company or any Restricted Subsidiary
of the Company, as the case may be, in connection with any Asset Sale is repaid or converted into
or sold or otherwise disposed of for cash (other than interest received with respect to any such
non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed
to constitute the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be
applied in accordance with this Section 4.15.

          If the Company or any Restricted Subsidiary engages in an Asset Sale, the Company or such
Restricted Subsidiary shall, no later than 365 days following the consummation thereof, apply all
or any of the Net Available Proceeds therefrom (or enter into a definitive agreement for such
application within such 365-day period, provided that any resulting capital expenditure or
purchase is closed within 90 days after the end of such 365-day period) to:

(1) satisfy all mandatory repayment obligations under the Credit Agreement arising by reason
of such Asset Sale;

(2) repay any Indebtedness which was secured by assets of the Company or a Restricted
Subsidiary;

(3) invest all or any part of the Net Available Proceeds thereof in the purchase of assets
(other than securities) to be used by the Company or any Restricted Subsidiary in a
Permitted Business; and/or

(4) if such Asset Sale was consummated by a Foreign Subsidiary, repay any Indebtedness of
such Foreign Subsidiary.

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

          The amount of Net Available Proceeds not applied or invested as provided in this Section
4.15(a) will constitute “Excess Proceeds.”

          (b) When the aggregate amount of Excess Proceeds equals or exceeds $10.0 million, the Company
shall make an offer to purchase from all Holders and, if applicable, redeem (or make an offer to do
so) any Pari Passu Indebtedness of the Company or any Guarantor the provisions of which require the
Company or such Guarantor to redeem such Indebtedness with the proceeds from any Asset Sales (or
offer to do so), in an aggregate principal amount of Notes and such Pari Passu Indebtedness equal
to the amount of such Excess Proceeds as follows:

 - 46 -

 

(1) the Company will (a) make an offer to purchase (a “Net Proceeds Offer”) to all
Holders in accordance with the procedures set forth in this Indenture, and (b) redeem (or
make an offer to do so) any such Pari Passu Indebtedness, pro rata in
proportion to the respective principal amounts of the Notes and such Pari Passu Indebtedness
required to be redeemed, the maximum principal amount of Notes and such Pari Passu
Indebtedness that may be redeemed out of the amount (the “Payment Amount”) of such
Excess Proceeds;

(2) the offer price for the Notes will be payable in cash in an amount equal to 100% of the
principal amount of the Notes tendered pursuant to a Net Proceeds Offer, plus accrued and
unpaid interest thereon, if any, to the date such Net Proceeds Offer is consummated (the
“Offered Price”), in accordance with the procedures set forth in this Indenture and
the redemption price for such Pari Passu Indebtedness (the “Pari Passu Indebtedness
Price”) shall be as set forth in the related documentation governing such Indebtedness;

(3) if the aggregate Offered Price of Notes validly tendered and not withdrawn by Holders
thereof exceeds the pro rata portion of the Payment Amount allocable to the
Notes, Notes to be purchased will be selected on a pro rata basis; and

(4) upon completion of such Net Proceeds Offer in accordance with the foregoing provisions,
the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall
be deemed to be zero.

          The Net Proceeds Offer will remain open for a period of at least 30 days following its
commencement but no longer than 60 days, except to the extent that a longer period is required by
applicable law. Promptly following the termination of the Net Proceeds Offer period the Company
will purchase the principal amount of Notes required to be purchased pursuant to this Section 4.15
or, if less than the Payment Amount allocated to the Notes has been so validly tendered and not
properly withdrawn, all Notes validly tendered and not properly withdrawn in response to the Net
Proceeds Offer. Payment for any Notes so purchased will be made in the same manner as principal
payments are to be made on the Notes at final maturity. If the purchase date for the Net Proceeds
Offer is on or after a 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 (to the extent involving interest that is
due and payable on such interest payment date) shall be payable to Holders who tender Notes
pursuant to the Net Proceeds Offer.

          Upon commencement of a Net Proceeds Offer, the Company shall send, by first class mail, a
notice to the Trustee and each of the Holders. The notice shall contain all instructions and
materials necessary to enable such Holders to tender Notes pursuant to the Net Proceeds Offer. The
Net Proceeds Offer shall be made to all Holders.

          On or before the purchase date for the Net Proceeds Offer the Company shall, to the extent
lawful, (1) accept for payment, on a pro rata basis to the extent necessary, the
Payment Amount allocated to the Notes pursuant to the Net Proceeds Offer, or if less than the
Payment Amount allocated to the Notes has been so validly tendered and not properly withdrawn, all

 - 47 -

 

Notes validly tendered and not properly withdrawn, (2) deposit by 11:00 A.M. New York City
time, on such date with the Paying Agent an amount in respect of all Notes, or portions thereof, so
accepted and (3) 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 4.15. The Company or the Paying Agent, as the case may be, shall promptly (but in any case
not later than five days after the expiration date for the Net Proceeds Offer) mail or deliver to
each tendering Holder an amount equal to the Offered Price of the Notes validly tendered and not
properly withdrawn by such Holders and accepted by the Company for purchase. Upon surrender and
cancellation of a Certificated Note that is purchased in part, the Company shall promptly issue and
the Trustee shall authenticate and deliver to the surrendering Holder of such Certificated Note a
new Certificated Note equal in principal amount to the unpurchased portion of such surrendered
Certificated Note; provided that each such new Certificated Note shall be in a principal
amount at Maturity of $1,000 or an integral multiple thereof. Upon surrender of a Global Note that
is purchased in part pursuant to a Net Proceeds Offer, the Paying Agent shall forward such Global
Note to the Notes Custodian who shall make a notation in its records to reduce the principal amount
of such Global Note to an amount equal to the unpurchased portion of such Global Note , as provided
in Section 2.01 hereof and the Appendix. Any Note not so accepted shall be promptly mailed or
delivered by the Company to the Holder thereof. The Company shall publicly announce the results of
the Net Proceeds Offer on or as soon as practical after the date of purchase. For purposes of this
Section 4.15, the Trustee shall act as the Paying Agent.

          To the extent that the sum of the aggregate Offered Price of Notes tendered pursuant to a Net
Proceeds Offer and the aggregate Pari Passu Indebtedness Price paid to the holders of such Pari
Passu Indebtedness is less than the Payment Amount relating thereto (such shortfall constituting a
“Net Proceeds Deficiency”), the Company may use the Net Proceeds Deficiency, or a portion
thereof, for general corporate purposes, subject to the provisions of this Indenture.

          (f) In the event of the transfer of substantially all (but not all) of the assets of the
Company and the Restricted Subsidiaries (taken as a whole) to a Person in a transaction covered by
and effected in accordance with Section 5.01 of this Indenture, the successor Person shall be
deemed to have sold for cash at Fair Market Value the assets of the Company and the Restricted
Subsidiaries not so transferred for purposes of this Section 4.15, and shall comply with the
provisions of this Section 4.15 with respect to such deemed sale as if it were an Asset Sale (with
such Fair Market Value being deemed to be Net Available Proceeds for such purpose).

          (g) The Company will comply with applicable tender offer rules, including the requirements of
Rule 14e-1 under the Exchange Act, and any other applicable laws and regulations in connection with
the purchase of Notes pursuant to a Net Proceeds 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 this compliance.

     Section 4.16. Limitations on Designation of Unrestricted Subsidiaries.

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

 - 48 -

 

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

(2) the Company would be permitted to make, at the time of such Designation, (a) a Permitted
Investment or (b) an Investment pursuant to Section 4.11(a) above, in either case, in an
amount (the “Designation Amount”) equal to the Fair Market Value of the Company’s
proportionate interest in such Subsidiary on such date.

          No Subsidiary shall be Designated as an “Unrestricted Subsidiary” unless such Subsidiary:

(1) has no Indebtedness other than Non-Recourse Debt;

(2) is not party to any agreement, contract, arrangement or understanding with the Company
or any Restricted Subsidiary unless the terms of the agreement, contract, arrangement or
understanding are no less favorable to the Company or the Restricted Subsidiary than those
that might be obtained at the time from Persons who are not Affiliates;

(3) is a Person with respect to which neither the Company nor any Restricted Subsidiary has
any direct or indirect obligation (a) to subscribe for additional Equity Interests or (b) to
maintain or preserve the Person’s financial condition or to cause the Person to achieve any
specified levels of operating results; and

(4) has not guaranteed or otherwise directly or indirectly provided credit support for any
Indebtedness of the Company or any Restricted Subsidiary, except for any guarantee given
solely to support the pledge by the Company or any Restricted Subsidiary of the Equity
Interests of such Unrestricted Subsidiary, which guarantee is not recourse to the Company or
any Restricted Subsidiary, and except to the extent the amount thereof constitutes a
Restricted Payment permitted pursuant to Section 4.11 of this Indenture.

If, at any time, any Unrestricted Subsidiary fails 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 the Subsidiary and any Liens on assets of such Subsidiary
shall be deemed to be incurred by a Restricted Subsidiary as of the date and, if the Indebtedness
is not permitted to be incurred under Section 4.10 or the Lien is not permitted under Section 4.13
the Company shall be in default of the applicable covenant.

          The Company may redesignate an Unrestricted Subsidiary as a Restricted Subsidiary (a
“Redesignation”) only if:

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

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

 - 49 -

 

          All Designations and Redesignations must be evidenced by resolutions of the Board of Directors
of the Company, delivered to the Trustee certifying compliance with the foregoing provisions.

     Section 4.17. Additional Note Guarantees.

          If, after the Issue Date, (a) the Company or any Restricted Subsidiary shall acquire or create
another Subsidiary (other than in any case a Foreign Subsidiary or Subsidiary that has been
designated an Unrestricted Subsidiary) or (b) any Unrestricted Subsidiary that is not a Foreign
Subsidiary is redesignated a Restricted Subsidiary, then, in each such case, the Company shall
cause such Restricted Subsidiary to:

(1) execute and deliver to the Trustee within 20 days (a) a supplemental indenture
substantially in the form included in Exhibit B hereto pursuant to which such
Restricted Subsidiary shall unconditionally guarantee all of the Company’s obligations under
the Notes and this Indenture and (b) a notation of guarantee in respect of its Note
Guarantee; and

(2) deliver to the Trustee one or more Opinions of Counsel that such supplemental indenture
(a) has been duly authorized, executed and delivered by such Restricted Subsidiary and (b)
constitutes a valid and legally binding obligation of such Restricted Subsidiary in
accordance with its terms.

          At the Company’s discretion, any Unrestricted Subsidiary may be made a Guarantor by complying
with the procedures set forth in the preceding clauses (1) and (2) of this Section 4.17.

     Section 4.18. Limitations on Layering Indebtedness.

          The Company will not, and will not permit any Guarantor to, directly or indirectly, incur any
Indebtedness that is or purports to be by its terms (or by the terms of any agreement governing
such Indebtedness) subordinated to any other Indebtedness of the Company or of such Guarantor, as
the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement
governing such Indebtedness) made expressly subordinate to the Notes or the Note Guarantee of such
Guarantor, to the same extent and in the same manner as such Indebtedness is subordinated to such
other Indebtedness of the Company or such Guarantor, as the case may be.

			
	Section 4.19.	 	Limitations on the Issuance or Sale of Equity

Interests of Restricted Subsidiaries.

          The Company will not, and will not permit any Restricted Subsidiary to, directly or
indirectly, sell or issue any Equity Interests of any Restricted Subsidiary except (1) to the
Company, a Restricted Subsidiary or the minority Equity Interest holders of any Restricted
Subsidiary, on a pro rata basis, at Fair Market Value, or (2) to the extent such
Equity Interests represent directors’ qualifying shares or Equity Interests required by applicable
law to be held by a Person other than the Company or a Wholly-Owned Restricted Subsidiary. The
sale of all the

 - 50 -

 

Equity Interests of any Restricted Subsidiary is permitted by this Section 4.19 but is subject
to Section 4.15 of this Indenture.

     Section 4.20. Limitations on Sale and Leaseback Transactions.

          The Company will not, and will not permit any Restricted Subsidiary to, directly or
indirectly, enter into any Sale and Leaseback Transaction; provided that the Company or any
Restricted Subsidiary may enter into a Sale and Leaseback Transaction if:

(1) the Company or such Restricted Subsidiary could have (a) incurred the Attributable
Indebtedness relating to such Sale and Leaseback Transaction pursuant to Section 4.10 and
(b) incurred a Lien to secure such Indebtedness without equally and ratably securing the
Notes pursuant to Section 4.13;

(2) the gross cash proceeds of such Sale and Leaseback Transaction are at least equal to the
Fair Market Value of the asset that is the subject of such Sale and Leaseback Transaction;
and

(3) the transfer of assets in such Sale and Leaseback Transaction is permitted by, and the
Company or the applicable Restricted Subsidiary applies the proceeds of such transaction in
accordance with, Section 4.15.

     Section 4.21. Suspension of Certain Covenants.

          Following the first day (the “Suspension Date”) that:

(1) the Notes have an Investment Grade Rating from both of the Rating Agencies, and

(2) no Default has occurred and is continuing under this Indenture,

the Company and its Restricted Subsidiaries shall not be subject to the provisions of this
Indenture under Sections 4.09, 4.10, 4.11, 4.12, 4.14, 4.15, 4.18, 4.19, subclause (a) of clause
(1) and clause (3) of Section 4.20 and Section 5.01(a)(3) (collectively, the “Suspended
Covenants”). The Company shall notify the Trustee promptly following the Suspension Date of
the suspension of the Suspended Covenants; provided that the failure to give such notice
promptly shall not affect the suspension of the Suspended Covenants. In the event that the Company
and its Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time
as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both
of the Rating Agencies withdraws its Investment Grade Rating or downgrades the rating assigned to
the Notes below an Investment Grade Rating, then the Company and the Restricted Subsidiaries shall
thereafter again be subject to the Suspended Covenants with respect to future events. The Company
shall notify the Trustee promptly following the Reversion Date of the reinstatement of the
Suspended Covenants. The period of time between the Suspension Date and the Reversion Date is
referred to in this Indenture as the “Suspension Period.” Notwithstanding that the
Suspended Covenants may be reinstated, no Default shall be deemed to have occurred as a result of a
failure to comply with the Suspended Covenants during the Suspension Period.

 - 51 -

 

          On the Reversion Date, all Indebtedness Incurred during the Suspension Period shall be
classified to have been incurred pursuant to Section 4.10(a) or one of the clauses set forth in
Section 4.10(b) (to the extent such Indebtedness would be permitted to be incurred thereunder as of
the Reversion Date and after giving effect to Indebtedness incurred prior to the Suspension Period
and outstanding on the Reversion Date). To the extent such Indebtedness would not be so permitted
to be incurred pursuant to Section 4.10(a) or (b), such Indebtedness shall be deemed to have been
outstanding on the Issue Date, so that it is classified as permitted under Section 4.10(b)(3).
Calculations made after the Reversion Date of the amount available to be made as Restricted
Payments under Section 4.11 shall be made as though Section 4.11 had been in effect since the Issue
Date and throughout the Suspension Period. Restricted Payments made during the Suspension Period
shall reduce the amount of the Restricted Payments Basket. For purposes of determining compliance
with Section 4.15, on the Reversion Date, the Net Available Proceeds from all Asset Sales not
applied in accordance with such Section shall be deemed to be reset to zero.

ARTICLE 5

SUCCESSORS

     Section 5.01. Limitation on Mergers, Consolidation, Etc.

          (a) The Company will not directly or indirectly, in a single transaction or a series of
related transactions, (a) consolidate or merge with or into (other than a merger with a Wholly
Owned Restricted Subsidiary solely for the purpose of changing the Company’s jurisdiction of
incorporation to another State of the United States), or sell, lease, transfer, convey or otherwise
dispose of all or substantially all of the assets of the Company or the Company and the Restricted
Subsidiaries (taken as a whole) or (b) consummate a Plan of Liquidation unless, in either case:

          (1) either:

     (a) the Company will be the surviving or continuing Person; or

     (b) the Person formed by or surviving such consolidation or merger or to which
such sale, lease, transfer, conveyance or other disposition shall be made (or, in
the case of a Plan of Liquidation, any Person to which assets are transferred)
(collectively, the “Successor”) is a corporation organized and existing
under the laws of any State of the United States of America or the District of
Columbia, and the Successor expressly assumes, by supplemental indenture in form and
substance satisfactory to the Trustee, all of the obligations of the Company under
the Notes, this Indenture and the relevant Registration Rights Agreement;

     (2) immediately prior to and immediately after giving effect to such transaction and
the assumption of the obligations as set forth in clause (1)(b) above and the incurrence of
any Indebtedness to be incurred in connection therewith, no Default shall have occurred and
be continuing; and

 - 52 -

 

     (3) immediately after and giving effect to such transaction and the assumption of the
obligations set forth in clause (1)(b) above and the incurrence of any Indebtedness to be
incurred in connection therewith, and the use of any net proceeds therefrom on a pro forma
basis, the Company or the Successor, as the case may be, could incur $1.00 of additional
Indebtedness pursuant to the Coverage Ratio Exception.

For purposes of this Section 5.01(a), any Indebtedness of the Successor which was not Indebtedness
of the Company immediately prior to the transaction shall be deemed to have been incurred in
connection with such transaction.

          (b) Except as provided in Section 10.04, no Guarantor may 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:

          (1) either

     (a) such Guarantor will be the surviving or continuing Person; or

     (b) the Person formed by or surviving any such consolidation or merger assumes,
by supplemental indenture in form and substance satisfactory to the Trustee, all of
the obligations of such Guarantor under the Note Guarantee of such Guarantor, this
Indenture and the relevant Registration Rights Agreement; and

     (2) immediately after giving effect to such transaction, no Default shall have occurred
and be continuing.

          For purposes of the foregoing, the disposition (by lease, assignment, sale or otherwise, in a
single transaction or series of related transactions) of all or substantially all of the assets of
one or more Restricted Subsidiaries, the Equity Interests of which constitute all or substantially
all of the assets of the Company, will be deemed to be the disposition of all or substantially all
of the assets of the Company.

     Section 5.02. Successor Substituted.

          Upon any consolidation or merger of the Company or a Guarantor, or any disposition of all or
substantially all of the assets of the Company or the Company and its Restricted Subsidiaries
(taken as a whole) in accordance with the foregoing, in which the Company or such Guarantor is not
the continuing obligor under the Notes or its Note Guarantee, the Person formed by such
consolidation or into which the Company or such Guarantor is merged or to which the disposition is
made will succeed to, and be substituted for, and may exercise every right and power of, the
Company or such Guarantor under this Indenture, the Notes and the Note Guarantees with the same
effect as if such Person had been named therein as the Company or such Guarantor and, except in the
case of a lease of all or substantially all of such assets, the Company will be released from the
obligation to pay the principal of and interest on the Notes and all of the Company’s other
obligations and covenants under the Note and this Indenture. Such Guarantor will be released from
its Note Guarantee on the conditions set forth in Section 10.04 hereof.

 - 53 -

 

          If the Successor shall have succeeded to and been substituted for the Company, such Successor
may cause to be signed, and may issue either in its own name or in the name of the Company prior to
such succession any or all of the Notes issuable hereunder which theretofore shall not have been
signed by the Company and delivered to the Trustee; and, upon the order of such Successor, instead
of the Company, and subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee shall authenticate and shall deliver any Notes which previously shall have
been signed and delivered by the Officers of the Company to the Trustee for authentication, and any
Notes which such Successor thereafter shall cause to be signed and delivered to the Trustee for
that purpose (in each instance with notations of Guarantees thereon by the Guarantors). All of the
Notes so issued and so endorsed shall in all respects have the same legal rank and benefit under
this Indenture as the Notes theretofore or thereafter issued and endorsed in accordance with the
terms of this Indenture and the Guarantees as though all such Notes had been issued and endorsed at
the date of the execution hereof.

          In case of any such transaction or series of transactions, such changes in phraseology and
form (but not in substance) may be made in the Notes thereafter to be issued or the Guarantees to
be endorsed thereon as may be appropriate.

          For all purposes of this Indenture and the Notes, Subsidiaries of any Successor will, upon
such transaction or series of transactions, become Restricted Subsidiaries or Unrestricted
Subsidiaries as provided pursuant to this Indenture and all Indebtedness, and all Liens on assets,
of the Successor and its Subsidiaries immediately prior to such transaction or series of
transactions shall be deemed to have been incurred upon such transaction or series of transactions.

 - 54 -

 

(5) default under any mortgage, indenture or other instrument or agreement under which there
may be issued or by which there may be secured or evidenced Indebtedness of the Company or
any Restricted Subsidiary, whether such Indebtedness now exists or is incurred after the
Issue Date, which default:

     (a) is caused by a failure to pay when due principal on such Indebtedness
within the applicable express grace period,

     (b) results in the acceleration of such Indebtedness prior to its express final
maturity or

     (c) results in the commencement of judicial proceedings to foreclose upon, or
to exercise remedies under applicable law or applicable security documents to take
ownership of, the assets securing such Indebtedness, and

in each case, the principal amount of such Indebtedness, together with any other
Indebtedness with respect to which an event described in clause (a), (b) or (c) has occurred
and is continuing, aggregates $20.0 million or more;

declared null and void and unenforceable or found to be invalid or any Guarantor denies its
liability under its Note Guarantee (other than by reason of release of a Guarantor from its
Note Guarantee in accordance with the terms of this Indenture and the Note Guarantee).

Section 6.02. Acceleration.

          If an Event of Default (other than an Event of Default specified in Section 6.01(7) or (8)
above with respect to the Company), shall have occurred and be continuing under this Indenture, the
Trustee, by written notice to the Company, or the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding by written notice to the Company and the Trustee, may declare
all amounts owing under the Notes to be due and payable immediately. Upon such declaration of
acceleration, the aggregate principal of, premium, if any, and accrued and unpaid interest on the
outstanding Notes shall immediately become due and payable. If an Event of Default specified in
Section 6.01(7) or (8) above with respect to the Company occurs, all outstanding Notes shall become
due and payable without any further action or notice.

          After any such acceleration, but before a judgment or decree based on acceleration, Holders of
a majority in aggregate principal amount of the outstanding Notes by notice to the Company and the
Trustee may rescind an acceleration and its consequences if:

     (a) the Company or any Guarantor has paid or deposited with the Trustee a sum
sufficient to pay

	 	(i)	 	all money paid or advanced by the Trustee
hereunder and the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other
amounts due to the Trustee under Section 7.07;
	 
	 	(ii)	 	all overdue installments of interest on,
and any other amounts due in respect of, all Notes;

acceleration and interest thereon at the rate or rates prescribed

	 	(iv)	 	to the extent that payment of such interest
is lawful, interest upon defaulted interest at the rate or rates
prescribed therefor in the Notes and this Indenture;

 - 56 -

 

     (b) all Events of Default, other than the nonpayment of principal of Notes
which have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 6.04;

     (c) the annulment of such acceleration would not conflict with any judgment or
decree of a court of competent jurisdiction; and

     (d) the Company has delivered an Officers’ Certificate to the Trustee to the
effect of clauses (b) and (c) of this sentence.

          No such rescission shall affect any subsequent Default or impair any right consequent thereto.

     Section 6.03. Other Remedies.

          Notwithstanding any other provision of this Indenture, if an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to
collect the payment of principal, premium, if any, or interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not
produce any of them in the proceeding. A delay or omission by the Trustee or any Holder 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.

          Subject to Sections 6.07 and 9.02 the Holders of a majority in aggregate principal amount of
the Notes then outstanding by notice to the Trustee may waive an existing Default or Event of
Default and its consequences. When a Default is waived, it is cured and ceases; but no such waiver
shall extend to any other Default.

     Section 6.05. Control by Majority.

          The Holders of a majority in aggregate principal amount of the Notes may direct the time,
method and place of conducting any proceeding for exercising any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee with respect to the Notes; provided
that such directions shall not be in conflict with any law or this Indenture. Before proceeding to
exercise any right or power under this Indenture at the direction of such Holders, the Trustee
shall be entitled to receive from such Holders reasonable security or indemnity satisfactory to it
against the costs, expenses and liabilities which might be Incurred by it in complying with any
such direction.

     Section 6.06. Limitation on Suits.

          Except as provided in Section 6.07, a Holder may pursue a remedy with respect to this
Indenture or the Notes only if:

 - 57 -

 

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

     (2) the Holders of at least 25% in aggregate principal amount of the Notes then
outstanding make a written request to the Trustee to institute proceedings in respect of
such Event of Default;

     (3) such Holder or Holders offer and, if requested, furnish to the Trustee security or
indemnity, satisfactory to the Trustee in its reasonable judgment, against any loss,
liability, claim, damage or expense to be thereby incurred (including reasonable attorneys’
fees);

     (4) the Trustee does not comply with the request within 60 days after receipt of the
request and the offer and, if requested, the furnishing of such security or indemnity; and

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

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

     Section 6.07. Rights of Holders To Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to
receive payment of principal, premium, if any, or interest in respect of any such Note on the
stated maturity expressed in such Note, on or after the respective due dates expressed in the Note,
or to bring suit for the enforcement of any such payment on or after such respective dates, shall
not be impaired or adversely affected without the consent of the Holder.

     Section 6.08. Collection Suit by Trustee.

          If an Event of Default specified in Section 6.01(l) or (2) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust against the Company
or any Guarantor for the whole amount of principal, premium, if any, and interest remaining unpaid.

     Section 6.09. Trustee May File Proofs of Claim.

          The Trustee may 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, any predecessor Trustee and the Holders
allowed in any judicial proceedings relative to the Company or any Guarantor, its
creditors or its property. All rights of action and claims under this Indenture may be
prosecuted and enforced by the Trustee without the possession of any of the Notes or the production
thereof in any proceeding related thereto. Any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust.

 - 58 -

 

          Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder of the Notes any plan of reorganization, arrangement,
adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize
the Trustee to vote in respect of the claim of any Holder of the Notes in any such proceeding.

     Section 6.10. Priorities.

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

     FIRST: to the Trustee for amounts due under Section 7.07;

     SECOND: to Holders for amounts due and unpaid on the Notes for principal,
premium, 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, if any, and
interest, respectively; and

     THIRD: to the Company, the Guarantors to such other party as a court of
competent jurisdiction shall direct.

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

     Section 6.11. Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit other than the Trustee of an undertaking to
pay the costs of the suit, and the court in its discretion may assess reasonable costs, including
reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard
to the merits and good faith of the claims or defenses made by the party litigant. This Section
6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit
by Holders of more than 10% in aggregate principal amount of the Notes then outstanding.

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 vested in it by this Indenture, and use the same degree of care
and skill in their exercise, as a prudent person would exercise or use under the circumstances
in the conduct of his own affairs.

 - 59 -

 

          (b) Except during the continuance of an Event of Default:

     (2) 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
certificates or opinions furnished to the Trustee and conforming to the requirements of this
Indenture. However, in the case of certificates or opinions required to be furnished to it
pursuant to any provision herein, the Trustee shall examine the certificates and opinions to
determine whether or not they substantially conform to the requirements of this Indenture
but need not verify the accuracy of the content thereof.

          (c) The Trustee may not be relieved from liability for its own negligent action, its own
negligent failure to act or its own willful misconduct, except that:

     (1) this paragraph does not limit the effect of paragraph (b) of this Section 7.01;

     (2) the Trustee shall not be liable for any error of judgment made in good faith by a
Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the
pertinent facts; and

take in good faith in accordance with a direction received by it pursuant to Section 6.05

(anticipated or actual which have or may arise), including reasonable attorneys’ fees.

          (f) The Trustee shall not be liable for interest on any money received by it except as the

          (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds
or otherwise incur any financial liability whatsoever in the performance of any of its duties
hereunder.

          (f) The Trustee shall be under no obligation to exercise any of the rights or powers vested
in it by this Indenture at the request or direction of any of the Holders pursuant to this

to the Trustee in its reasonable judgment against the costs, expenses and liabilities which might
be incurred by it in compliance with such request or direction.

          (g) The Trustee shall not be deemed to have notice of any Default or Event of Default, except
any Default or Event of Default occurring pursuant to Section 6.01(1) or 6.01 (2) hereof, unless a

which is in fact such a default is received by the Trustee at its address specified in Section
11.02 hereof, and such notice references the Notes and this Indenture.

          (h) The rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be
enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and
other Person employed to act hereunder.

          (i) The Trustee may request that the Company deliver an Officers’ Certificate setting forth
the names of individuals an/or titles of officers authorized at such time to take specified actions

certificate previously delivered and not superseded.

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

 - 61 -

 

          (k) In no event shall the Trustee be responsible or liable for special, indirect or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit)
irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.

     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 a Related Person thereof with the same rights it would
have if it were not Trustee. Any Agent may do the same with like rights. The Trustee, however,
must comply with Sections 7.10 and 7.11.

     Section 7.04. Trustee’s Disclaimer.

          The Trustee makes no representation as to the validity or adequacy of this Indenture or the
Notes or Note Guarantees; it shall not be accountable for the Company’s use of the proceeds from

Notes, give the Holders notice of all uncured Defaults thereunder known to it; provided,
however, that, except in the case of an Event of Default in payment with respect to the
Notes or a Default in complying with Section 5.01, the Trustee shall be protected in withholding
such notice if and so long as a committee of its Trust Officers in good faith determines that the
withholding of such notice is in the interest of the Holders.

     Section 7.06. Reports by Trustee to Holders.

          If required by TIA Section 313(a), within 60 days after each January 1 beginning with January
1, 2007, the Trustee shall mail to each Holder as required by TIA Section 313(c) a brief report
dated as of such date that complies with TIA Section 313(a). The Trustee also shall comply with
TIA Section 313(b) and (c).

          A copy of each report at the time of its mailing to Holders shall be filed by the Trustee with
the SEC and each stock exchange, if any, on which the Notes are listed. The Company shall notify
the Trustee when the Notes are listed on any stock exchange or delisted therefrom.

     Section 7.07. Compensation and Indemnity.

          The Company shall pay to the Trustee from time to time such compensation for its services as
shall be agreed upon in writing between 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 promptly reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred by it in connection with administering this Indenture. Such expenses

 - 62 -

 

shall include the
reasonable compensation and out-of-pocket expenses of the Trustee’s agents and counsel.

          The Company shall fully indemnify the Trustee and hold it harmless against any and all loss,
claim, damage, expense or liability (including the reasonable fees and expenses of counsel)
incurred by it in connection with the administration of this Indenture and the performance of its
duties hereunder. The Company need not pay for any settlement made without its consent. The
Trustee shall notify the Company promptly of any claim for which it may seek indemnification. The
Company need not reimburse any expense or indemnify against any loss or liability incurred by the
Trustee as determined to have been caused by the Trustee’s own negligence, bad faith or willful
misconduct.

          To secure the Company’s payment Obligations in this Section, the Trustee shall have a Lien
prior to the Notes on all money or property held or collected by the Trustee, except that held in
trust to pay principal, premium, if any, or interest on particular Notes.

          When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 6.01(7) or (8) occurs, the expenses and the compensation for the services are intended to
constitute expenses of administration under any Bankruptcy Law.

          The Trustee shall comply with the provisions of TIA Section 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
7.08.

          The Trustee may resign by so notifying the Company in writing. The Holders of a majority in
principal amount of the Notes may remove the Trustee by so notifying in writing the Trustee and the
Company and may appoint a successor Trustee with the Company’s consent. The Company may remove the
Trustee if:

     (1) the Trustee fails to comply with Section 7.10;

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

     (3) a receiver or other public officer takes charge of the Trustee or its property; or

     (4) the Trustee becomes incapable of acting.

          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 Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the Company.

 - 63 -

 

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

          If the Trustee fails to comply with Section 7.10, any Holder who has been a Holder for at
least six months 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 the
Holders. The retiring Trustee shall upon payment of its charges hereunder promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the Lien provided for in
Section 7.07.

          Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the Company’s
obligation to compensate the retiring Trustee under Section 7.07 for services rendered prior to its
retirement and the Company’s obligation to indemnify the Trustee under Section 7.07 shall continue
for the benefit of the retiring Trustee and shall survive termination of this Indenture.

     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, the successor corporation without any further
act shall be the successor Trustee.

          In case at the time any such successor to the Trustee by merger, conversion, consolidation or
transfer shall succeed to the trusts created by this Indenture any of the Notes shall have been
authenticated but not delivered, such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Notes so authenticated; and in case at
that time any of the Notes shall not have been authenticated, any successor to the Trustee may
authenticate such Notes either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all cases such certificates shall have the full force which it is
anywhere in the Notes or in this Indenture.

     Section 7.10. Eligibility; Disqualification.

          This Indenture shall always have a Trustee who satisfies the requirements of TIA Section
310(a)(1), (2) and (5). The Trustee shall always have a combined capital and surplus of at least
$50,000,000 as set forth in its most recent published annual report of condition. The Trustee
shall comply with TIA Section 310(b), provided that there shall be excluded from the
operation of TIA Section 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 and
meeting the requirements for exclusion set forth in TIA Section 310(b)(1).

- 64 -

 

     Section 7.11. Preferential Collection of Claims Against Company.

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

ARTICLE 8

     Section 8.01. Option to Effect Defeasance or Covenant Defeasance.

          The Company may, at the option of its Board of Directors evidenced by a resolution of its
Board of Directors, a copy of which shall be delivered to the Trustee, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the

8.02, the Company and the Guarantors shall, subject to the satisfaction of the conditions set forth
in Section 8.04 hereof, be deemed to have been discharged from their respective Obligations with
respect to all outstanding Notes, this Indenture and the Guarantees on the date the conditions set
forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Defeasance
means that the Company and the Guarantors shall be deemed to have paid and discharged the entire
Indebtedness represented by the outstanding Notes and the Company and the Guarantors shall be
deemed to have satisfied all of their obligations under such Notes, this Indenture and the
Guarantees (and the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until otherwise terminated or
discharged hereunder:

     (a) the rights of Holders of such Notes to receive, solely from the trust fund
described in Section 8.04 hereof and as more fully set forth in Section 8.04,
payments in respect of the principal of, any premium, if any, and interest on such
Notes when payments are due (but not the Change of Control Purchase Price or the
Offered Price),

     (b) the Company’s obligations with respect to such Notes under Sections 2.05,
2.06, 2.07, 2.08, 2.10, and 4.02 hereof,

     (c) the rights, powers, trusts, duties and immunities of the Trustee under this
Indenture, and the Company’s obligations in connection therewith,

     (d) the Company’s rights of optional redemption in respect of any Notes that it
has called for redemption prior to the Legal Defeasance, and

     (e) this Article 8.

- 65 -

 

Subject to compliance with this Article 8, the Company may exercise its option under this Section
8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

     Section 8.03. Covenant Defeasance.

          Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section
8.03, (i) the Company and the Guarantors shall, subject to the satisfaction of the conditions set
forth in Section 8.04 hereof, be released from all obligations under the covenants contained in
Sections 4.03, 4.04, 4.06 (with regard to Restricted Subsidiaries only), 4.07, 4.08, 4.09, 4.10,
4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 and Sections 5.01(a)(3) and 5.01(b)
hereof, except to the extent that any such obligations under Sections 4.03 and 4.04 are mandated by
the TIA, and any covenant added to this Indenture subsequent to the Issue Date pursuant to Section
9.01 hereof with respect to the outstanding Notes and (ii) the occurrence of any event specified in
Section 6.01(3) or 6.01(4) hereof, with respect to any of Sections 4.03, 4.04, 4.07, 4.08, 4.09,
4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 and Sections 5.01(a)(iii) and
5.01(b) hereof, and any covenant added to this Indenture subsequent to the Issue Date pursuant to
Section 9.01 hereof, shall be deemed not to be or result in an Event of Default, in each case with
respect to such Notes as provided in this Section 8.03 on and after the date on which the
conditions set forth in Section 8.04 hereof are satisfied, 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 to the extent permitted by GAAP). For this
purpose, “Covenant Defeasance” means that, with respect to the outstanding Notes, the
Company and the Guarantors may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in any such covenant (to the extent so specified in the
case of Section 6.01(3) or 6.01(4) hereof), 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, the Guarantees and the Notes shall be unaffected thereby.
In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this
Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
clauses (5), (6) and (9) of Section 6.01 hereof shall not constitute Events of Default, and 91 days
following the deposit referred to in clause (1) of Section 8.04 hereof, clauses (7) and (8) of
Section 6.01 hereof shall not constitute Events of Default. Notwithstanding any contrary provision
of this Article 8, Covenant Defeasance shall not be effective until 91 days following such deposit.

     Section 8.04. Conditions to Defeasance or Covenant Defeasance.

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

          In order to exercise either Legal Defeasance or Covenant Defeasance:

- 66 -

 

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the
Holders, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such
amounts as will be sufficient (without reinvestment) in the opinion of a nationally
recognized firm of independent public accountants selected by the Company,
to pay the principal of, premium, if any, on and interest on the Notes on the stated date
for payment or on the redemption date of the principal or installment of principal of or
interest on the Notes, and the Holders must have a valid, perfected, exclusive security
interest in such trust,

(2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an
Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming
that:

     (a) the Company has received from, or there has been published by the Internal
Revenue Service, a ruling, or

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

in either case to the effect that, and based thereon this Opinion of Counsel shall confirm
that, the Holders will not recognize income, gain or loss for U.S. federal income tax
purposes as a result of the Legal Defeasance and will be subject to U.S. federal income tax
on the same amounts, in the same manner and at the same times as would have been the case if
such Legal Defeasance had not occurred,

(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 U.S. federal income tax purposes as
a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the
same amounts, in the same manner and at the same times as would have been the case if the
Covenant Defeasance had not occurred,

(4) no Default shall have occurred and be continuing on the date of such deposit (other than
a Default resulting from the borrowing of funds to be applied to such deposit and the grant
of any Lien securing such borrowing),

(5) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation
of, or constitute a default under this Indenture or any other material agreement or
instrument to which the Company 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 it with the intent of preferring the Holders over any other of
its creditors or with the intent of defeating, hindering, delaying or defrauding any other
of its creditors or others, and

(7) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion
of Counsel, each stating that the conditions provided for in, in the case of

- 67 -

 

the Officers’ Certificate, clauses (1) through (6) and, in the case of the Opinion of Counsel, clauses (1)
(with respect to the validity and perfection of the security interest), (2) and/or (3) and
(5) of this paragraph have been complied with.

          If the funds deposited with the Trustee to effect Covenant Defeasance are insufficient to pay
the principal of, premium, if any, and interest on the Notes when due, then the Company’s
obligations and the obligations of Guarantors under this Indenture will be revived and no such
defeasance will be deemed to have occurred.

     Section 8.05. Termination of the Obligations by Satisfaction or Pursuant to
Redemption.

          This Indenture shall upon the request of the Company be discharged and cease to be of further
effect (except as provided in the penultimate paragraph of this Section 8.05) and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture if:

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

(2) (a) all Notes not delivered to the Trustee for cancellation otherwise have become due
and payable or will become due and payable within one year by reason of the mailing of a
notice of redemption or otherwise, and the Company has irrevocably deposited or caused to be
deposited with the Trustee funds in trust in an amount of money sufficient to pay and
discharge the entire Indebtedness (including all principal, premium, if any, and accrued and
unpaid interest) on the Notes not theretofore delivered to the Trustee for cancellation,

(3) the Company has paid all sums payable by it under this Indenture, and

(4) the Company has delivered irrevocable instructions to the Trustee to apply the deposited
money toward the payment of the Notes at stated maturity or on the date of redemption, as
the case may be.

          In addition, the Company must deliver an Officers’ Certificate and an Opinion of Counsel
stating that all conditions precedent to satisfaction and discharge have been complied with.

          Notwithstanding the satisfaction and discharge of this Indenture, the Company’s obligations in
Sections 2.05, 2.06, 2.07, 2.08, 2.10, 7.07, 7.08, and this Article 8, and the Trustee’s and Paying
Agent’s obligations in Section 8.06 shall survive until the Notes are no longer outstanding.
Thereafter, only the Company’s obligations in Sections 7.07 and 8.07 and the Trustee’s and Paying
Agent’s obligations in Sections 8.06 and 8.07 shall survive.

- 68 -

 

          In order to have money available on a payment date to pay principal (and premium, if any, on)
or interest on the Notes, the U.S. Government Obligations shall be payable as to principal (and
premium, if any) or interest (including Liquidated Damages, if any) at least one Business Day
before such payment date in such amounts as will provide the necessary money.

     Section 8.06. Application of Trust Money.

          All money deposited with the Trustee pursuant to Section 8.04 or 8.05 shall be held in trust
and, at the written direction of the Company, be invested prior to maturity in U.S. Government
Obligations, and applied by the Trustee in accordance with the provisions of the Notes and this
Indenture, to the payment, either directly or indirectly 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.

     Section 8.07. Repayment to the Company.

          The Trustee and the Paying Agent shall promptly pay to the Company upon written request any
excess money or securities held by them at any time.

          The Trustee and the Paying Agent shall pay to the Company upon written request any money held
by them for the payment of principal, premium, if any, or interest that remains unclaimed for two
years after the date upon which such payment shall have become due; provided, that the
Company shall have either caused notice of such payment to be mailed to each Holder of the Notes
entitled thereto no less than 30 days prior to such repayment or within such period shall have
published such notice in a financial newspaper of widespread circulation published in The City of
New York, including, without limitation, The Wall Street Journal (national edition). After payment
to the Company, Holders entitled to the money must look to the Company for payment as general
creditors unless an applicable abandoned property law designates another Person, and all liability
of the Trustee and such Paying Agent with respect to such money shall cease.

     Section 8.08. Reinstatement.

          If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in
accordance with Section 8.06 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Company’s and Guarantors’ Obligations under this Indenture, the Notes and the
Guarantees shall be revived and reinstated as though no deposit has occurred pursuant to Section
8.04 or 8.05 until such time as the Trustee or Paying Agent is permitted to apply all such money or
U.S. Government Obligations in accordance with Section 8.06, provided, however,
that if the Company or the Guarantors have made any payment of interest on or principal (and
premium, if any) of any Notes because of the reinstatement of their Obligations, the Company or
such Guarantors shall be subrogated to the rights of the Holders of such Notes to receive such
payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

     (3) reduce any premium payable upon optional redemption of the Notes, change

to affect the ranking of the Notes or any Note Guarantee in a manner that adversely
affects the Holders;

     (6) reduce the percentage of Holders necessary to consent to an amendment or
waiver to this Indenture or the Notes;

     (7) impair the right of any Holder of the Notes to receive payment of principal

          Every amendment to this Indenture, the Notes or the Note Guarantees shall comply with the TIA
as then in effect.

- 71 -

 

     Section 9.04. Revocation and Effect of Consents.

          Until an amendment or waiver becomes effective, a consent to it by a Holder of a Note is a
continuing consent by the Holder 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 or subsequent Holder may revoke the consent as to his
Note or portion of a Note if the Trustee receives notice of revocation before the date the
amendment or waiver becomes effective. An amendment or waiver becomes effective in accordance with
its terms and thereafter binds every Holder.

          The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to give their consent or take any other action described above or
required or permitted to be taken pursuant to this Indenture. If a record date if fixed, then
notwithstanding the immediately preceding subsection, those Persons who were Holders at such record
date (or their designated proxies), and only those Persons, shall be entitled to give such consent
or to revoke any consent previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No consent shall be valid or effective for more
than 120 days after such record date.

          After an amendment or waiver becomes effective with respect to this Indenture or the Notes, it
shall bind every Holder unless it makes a change described in any of clauses (1) through (9) of
Section 9.02. In that case the amendment or waiver shall bind each Holder of a Note who has
consented to it, and provided that notice of such amendment or waiver is reflected on a Note that
evidences the same debt as the consenting Holder’s Note, every subsequent Holder of a Note or
portion of a Note that evidences the same debt as the consenting Holder’s Note.

     Section 9.05. Notation on or Exchange of Notes.

          If an amendment or waiver changes the terms of a Note, the Trustee may require the Holder of
the Note to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note
about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate
a new Note that reflects the changed terms. Failure to make the appropriate notation or issue a
new Note shall not affect the validity and effect of such amendment or waiver.

     Section 9.06. Trustee Protected.

          The Trustee need not sign any amendment or waiver authorized pursuant to this Article that the
Trustee shall conclude in its reasonable judgment adversely affects the Trustee’s rights. The
Trustee shall be provided with and may conclusively rely upon an Opinion of Counsel and an
Officers’ Certificate that any supplemental indenture complies with this Indenture.

ARTICLE 10

GUARANTEE OF NOTES

     Section 10.01. Guarantee.

          Subject to the provisions of this Article 10, each Guarantor, by execution of this Indenture,
jointly and severally, unconditionally guarantees to each Holder (i) the due and punctual payment
of the principal of, premium, if any, and interest on each Note, when and as the same shall become
due and payable, whether at stated maturity, by acceleration or otherwise, the due and punctual
payment of interest on the overdue principal of, premium, if any, and interest on the Notes, to the
extent lawful, and the due and punctual payment of all other Obligations and due and punctual
performance of all obligations of the Company to the Holders or the Trustee all in accordance with
the terms of such Note, this Indenture and each Registration Rights Agreement, and (ii) in the case
of any extension of time of payment or renewal of any Notes or any of such other Obligations, that
the same will be promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, at stated maturity, by acceleration or otherwise.

     Section 10.02. Execution and Delivery of Notation of Note Guarantee.

          To further evidence the Note Guarantee set forth in Section 10.01, each Guarantor hereby
agrees that a notation of such Note Guarantee, substantially in the form included in Exhibit
C hereto, shall be endorsed on each Note authenticated and delivered by the Trustee and such
notation of Note Guarantee shall be executed by either manual or facsimile signature of an officer
or an officer of a general partner, as the case may be, of each Guarantor. The validity and
enforceability of any Note Guarantee shall not be affected by the fact that a notation thereof is
not affixed to any particular Note.

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

          If an officer of a Guarantor whose signature is on this Indenture or a notation of Note
Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such
notation of Note Guarantee is endorsed or at any time thereafter, such Guarantor’s guarantee of
such Note shall be valid nevertheless.

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

     Section 10.03. Limitation of Guarantee.

          The obligations of each Subsidiary Guarantor under its Note Guarantee will be limited to the
maximum amount as will, after giving effect to all other contingent and fixed liabilities of such
Guarantor (including, without limitation, any guarantees of Indebtedness of the

- 73 -

 

 Company under the Credit Agreement permitted under Section 4.10 of this Indenture) and after
giving effect to any collections from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under its Note Guarantee or pursuant to its
contribution obligations under this Indenture, result in the obligations of such Guarantor under
its Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal,
state, or foreign law. Each Guarantor that makes a payment for distribution under its Note
Guarantee is entitled to a contribution from each other Guarantor in a pro rata amount based on
adjusted net assets of each Guarantor.

     Section 10.04. Release of Guarantor.

          In the event of 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 of
the Equity Interests of any Guarantor then held by the Company and the Restricted Subsidiaries,
except in any case to the Company or any Restricted Subsidiary, then that Guarantor will be
released and relieved of any obligations under its Note Guarantee; provided that the Net
Available Proceeds of such sale or other disposition are applied in accordance with Section 4.15 of
this Indenture. Any Guarantor that is designated as an Unrestricted Subsidiary or that otherwise
ceases to be a Guarantor, in each case in accordance with the provisions of this Indenture, will be
released from its Note Guarantee upon effectiveness of such Designation or when it first ceases to
be a Restricted Subsidiary, as the case may be.

          The Trustee shall deliver an appropriate instrument provided to it evidencing the release of a
Guarantor upon receipt of a request of the Company accompanied by an Officers’ Certificate
certifying as to the compliance with this Section 10.04. Any Guarantor not so released or the
entity surviving such Guarantor, as applicable, will remain or be liable under its Note Guarantee
as provided in this Article 10.

          The Trustee shall execute any documents reasonably requested by the Company or a Guarantor in
order to evidence the release of such Guarantor from its obligations under its Note Guarantee
endorsed on the Notes and under this Article 10.

     Section 10.05. Waiver of Subrogation.

          Until such time as the Notes and the other Obligations of the Company guaranteed hereof have
been satisfied in full, each Guarantor hereby irrevocably waives any claim or other rights which it
may now or hereafter acquire against the Company that arise from the existence, payment,
performance or enforcement of such Guarantor’s obligations under its Note Guarantee and this
Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration,
indemnification, and any right to participate in any claim or remedy of any Holder of Notes against
the Company, whether or not such claim, remedy or right arises in equity, or under contract,
statute or common law, including, without limitation, the right to take or receive from the
Company, directly or indirectly, in cash or other property or by set-off or in any other manner,
payment or Note on account of such claim or other rights. If any amount shall be paid to any
Guarantor in violation of the preceding sentence and the Notes shall not have been paid in full,
such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held
in trust for the benefit of, the Holders, and shall forthwith be paid to the

- 74 -

 

 Trustee for the benefit of such Holders to be credited and applied upon the Notes, whether
matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges
that it will receive direct and indirect benefits from the financing arrangements contemplated by
this Indenture and that the waiver set forth in this Section 10.05 is knowingly made in
contemplation of such benefits.

such counsel, all such conditions precedent have been complied with.

          In any case where several matters are required to be certified by, or covered by an opinion

the opinion of, only one such Person, or that they be so certified or covered by only one document,
but one such Person may certify or give an opinion with respect to some matters and one or more

representations by, an Officer or Officers of the Company or such Guarantor stating that the
information with respect to such factual matters is in the possession of the Company or such
Guarantor, unless such counsel knows, or in the exercise of reasonable care should know, that the

          Where any Person is required to make, give or execute two or more applications, requests,
consents, certificates, statements, opinions or other instruments under this Indenture, they may,
but need not, be consolidated and form one instrument.

under the Notes or this Indenture or of any Guarantor under its Note Guarantee or for any claim
based on, in respect of, or by reason of, such obligations or their creation. Each Holder by

the foregoing, nothing herein shall prevent the Company, the Guarantors, the Trustee or any agent
of the Company, the Guarantors or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by the Depository or impair, as between the Depository and
its Agent Members, the operation of customary practices of such Depository governing the exercise
of the rights of a holder of a beneficial interest in any Global Note.

     Until the 40th day after the later of the commencement of the offering of any Initial Notes
and the original issue date of such Initial Notes (such period, the “Distribution Compliance
Period”), a beneficial interest in a Restricted Global Note representing Regulation S Notes may
be transferred to a Person who takes delivery in the form of an interest in a Restricted Global
Note representing Rule 144A Notes only if the transferor first delivers to the Trustee a written
certificate (in the form provided in Exhibit A hereto) to the effect that such transfer is being
made to a Person who the transferor reasonably believes is purchasing for its own account or
accounts as to which it exercises sole investment discretion and that such Person is a QIB, in each
case in a transaction meeting the requirements of Rule 144A and in accordance with any applicable
securities laws of any state of the United States or any other jurisdiction. After the expiration
of the Distribution Compliance Period, such certification requirements shall not apply to such
transfers of beneficial interests in a Restricted Global Note representing Regulation S Notes.

     Beneficial interests in a Restricted Global Note representing Rule 144A Notes may be
transferred to a Person who takes delivery in the form of an interest in a Restricted Global Note
representing Regulation S Notes, whether before or after the expiration of the Distribution

Compliance Period, only if the transferor first delivers to the Trustee a written certificate
(in the form provided in Exhibit A hereto) to the effect that such transfer is being made in
accordance with Rule 904 of Regulation S.

          (c) Certificated Notes. Except as provided in Section 2.3 or 2.4, owners of

an aggregate principal amount specified in the Company Request of the Company pursuant to Section
2.02 of the Indenture and (3) Exchange Notes or Private Exchange Notes for issue only in a
Registered Exchange Offer or a Private Exchange, respectively, pursuant to a Registration Rights
Agreement, for a like principal amount of Initial Notes, in each case upon a Company Request. Such
Company Request shall specify the amount of the Notes to be authenticated, the date on which the
original issue of Notes is to be authenticated and to whom the Notes shall be registered and
delivered and, in the case of any issuance of Additional Notes pursuant to Section 2.16 of the
Indenture, shall certify that such issuance is in compliance with Section 4.10 of the Indenture.

     2.3 Transfer and Exchange.

     (a) Transfer and Exchange of Global Notes. (i) The transfer and exchange of Global
Notes or beneficial interests therein shall be effected through the Depository, in accordance with
this Indenture (including applicable restrictions on transfer set forth herein, if any) and the
procedures of the Depository therefor. A transferor of a beneficial interest in a Global Note
shall deliver to the Registrar a written order given in accordance with the Depository’s procedures
containing information regarding the participant account of the Depository to be credited with a
beneficial interest in the Global Note. The Registrar shall, in accordance with such instructions
instruct the Depository to credit to the account of the Person specified in such instructions a
beneficial interest in the Global Note and to debit the account of the Person making the transfer
the beneficial interest in the Global Note being transferred.

     (ii) Notwithstanding any other provisions of this Appendix, a Global Note may not be
transferred as a whole except by the Depository to a nominee of the Depository or by a
nominee of the Depository to the Depository or another nominee of the Depository or by the
Depository or any such nominee to a successor Depository or a nominee of such successor
Depository.

     (iii) In the event that a Restricted Global Note is exchanged for Notes in certificated
form pursuant to Section 2.4 of this Appendix, prior to the consummation of a Registered
Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such
Notes, such Notes may be exchanged only in accordance with such procedures as are
substantially consistent with the provisions of this Section 2.3 (including the
certification requirements set forth on the reverse of the Initial Notes intended to ensure
that such transfers comply with Rule 144A or Regulation S, as the
case may be) and such other procedures as may from time to time be adopted by the
Company.

     (b) Restricted Notes Legend.

     (i) Except as permitted by the following paragraphs (ii), (iii) and (iv), each Note
certificate evidencing the Restricted Global Notes (and all Notes issued in exchange
therefor or in substitution thereof) shall bear a legend in substantially the following
form:

THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER THIS NOTE NOR ANY INTEREST OR
PARTICIPATION HEREIN MAY BE OFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR
OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS
EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THE
HOLDER OF THIS NOTE BY ITS ACCEPTANCE HEREOF AGREES TO OFFER, SELL OR OTHERWISE TRANSFER
SUCH SECURITY, PRIOR TO THE DATE WHICH IS TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE
DATE HEREOF AND THE LAST DATE ON WHICH THE COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE
OWNER OF THIS NOTE (OR ANY PREDECESSOR OF THIS NOTE) (THE “RESALE RESTRICTION TERMINATION
DATE”) ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) PURSUANT TO AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE NOTES ARE ELIGIBLE
FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT (“RULE 144A”), TO A PERSON IT
REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A THAT
PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM
NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO
OFFERS AND SALES TO NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING
OF REGULATION S UNDER THE SECURITIES ACT OR (E) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM
THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S AND THE
TRUSTEE’S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER (i) PURSUANT TO CLAUSE (D) PRIOR
TO THE END OF THE 40 DAY DISTRIBUTION COMPLIANCE PERIOD WITHIN THE MEANING OF REGULATION S
UNDER THE SECURITIES ACT OR PURSUANT TO CLAUSE (E) PRIOR TO THE RESALE RESTRICTION
TERMINATION DATE TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR
OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND (ii) IN EACH OF THE FOREGOING CASES, TO
REQUIRE THAT A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THIS NOTE IS COMPLETED AND
DELIVERED BY THE TRANSFEROR TO THE TRUSTEE. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF
A HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE.

     (ii) Upon any sale or transfer of a Transfer Restricted Security (including any
Transfer Restricted Security represented by a Restricted Global Note) pursuant to Rule 144,
with the Company’s prior approval the Registrar shall permit the transferee thereof

- 5 -

 

to exchange such Transfer Restricted Security for a Certificated Note that does not bear the
legend set forth above and rescind any restriction on the transfer of such Transfer
Restricted Security, if the transferor thereof certifies in writing to the Registrar that
such sale or transfer was made in reliance on Rule 144 (such certification to be in the form
set forth on the reverse of the Note).

     (iii) After a transfer of any Initial Notes or Private Exchange Notes pursuant to and
during the period of the effectiveness of a Shelf Registration Statement with respect to
such Initial Notes or Private Exchange Notes, as the case may be, all requirements
pertaining to legends on such Initial Note or such Private Exchange Note will cease to
apply, the requirements requiring any such Initial Note or such Private Exchange Note issued
to certain Holders be issued in global form will cease to apply, and a certificated Initial
Note or Private Exchange Note or an Initial Note or Private Exchange Note in global form, in
each case without restrictive transfer legends, will be available to the transferee of the
Holder of such Initial Notes or Private Exchange Notes upon exchange of such transferring
Holder’s certificated Initial Note or Private Exchange Note or directions to transfer such
Holder’s interest in the Global Note, as applicable.

     (iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial
Notes, all requirements pertaining to such Initial Notes that Initial Notes issued to
certain Holders be issued in global form will still apply with respect to Holders of such
Initial Notes that do not exchange their Initial Notes, and Exchange Notes in certificated
or global form will be available to Holders that exchange such Initial Notes in such
Registered Exchange Offer.

     (v) Upon the consummation of a Private Exchange with respect to the Initial Notes, all
requirements pertaining to such Initial Notes that Initial Notes issued to certain Holders
be issued in global form will still apply with respect to Holders of such Initial Notes that
do not exchange their Initial Notes, and Private Exchange Notes in global form with the
global Notes legend and the Restricted Notes legend set forth in Exhibit A hereto will be
available to Holders that exchange such Initial Notes in such Private Exchange.

     (c) Cancellation or Adjustment of Global Note. At such time as all beneficial
interests in a Global Note have either been exchanged for Certificated Notes, redeemed or canceled,
such Global Note shall be returned to the Trustee for cancellation or retained and canceled by the
Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is
exchanged for Certificated Notes, redeemed or canceled, the principal amount of Notes represented
by such Global Note shall be reduced and an adjustment shall be made on the books and records of
the Notes Custodian to reflect such reduction.

     (d) Obligations with Respect to Transfers and Exchanges of Notes.

     (i) To permit registrations of transfers and exchanges, the Company shall execute and
the Trustee shall authenticate Certificated Notes and Global Notes at the Registrar’s
request.

     (ii) All Notes issued upon any transfer or exchange pursuant to the terms of this
Indenture shall evidence the same debt and shall be entitled to the same benefits under this
Indenture as the Notes surrendered upon such transfer or exchange.

- 6 -

 

     (e) No Obligation of the Trustee.

     (i) The Trustee shall have no responsibility or obligation to any beneficial owner of a
Global Note, a member of, or a participant in the Depository or other Person with respect to
the accuracy of the records of the Depository or its nominee or of any participant or member
thereof, with respect to any ownership interest in the Notes or with respect to the delivery
to any participant, member, beneficial owner or other Person (other than the Depository) of
any notice (including any notice of optional redemption) or the payment of any amount, under
or with respect to such Notes. All notices and communications to be given to the Holders
and all payments to be made to Holders under the Notes shall be given or made only to or
upon the order of the registered Holders (which shall be the Depository or its nominee in
the case of a Global Note). The rights of beneficial owners in any Global Note shall be
exercised only through the Depository subject to the applicable rules and procedures of the
Depository. The Trustee may rely and shall be fully protected in relying upon information
furnished by the Depository with respect to its members, participants and any beneficial
owners.

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

     2.4 Certificated Notes.

     (a) A Global Note deposited with the Depository or with the Trustee as Notes Custodian shall
be transferred to the beneficial owners thereof in the form of certificated Notes
(“Certificated Notes”) in an aggregate principal amount equal to the principal amount of
such Global Note, in exchange for such Global Note, only if such transfer complies with Section 2.3
and (i) the Depository notifies the Company that it is unwilling or unable to continue as
Depository for such Global Note or if at any time such Depository ceases to be a “clearing agency”
registered under the Exchange Act and in either event a successor depositary is not appointed by
the Company within 90 days, or (ii) a Default has occurred and is continuing and DTC notifies the
Trustee of its decision to exchange the Global Note for Certificated Notes.

     (b) Any Global Note that is transferable to the beneficial owners thereof pursuant to this
Section shall be surrendered by the Depository or the Notes Custodian to the Trustee located at its
Corporate Trust Office to be so transferred, in whole or from time to time in part, without charge,
and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global
Note, an equal aggregate principal amount of Certificated Notes of authorized denominations. Any
portion of a Global Note transferred pursuant to this Section shall be executed, authenticated and
delivered only in denominations of $1,000 principal amount and any
integral multiple thereof and registered in such names as the Depository shall direct. Any
Certificated Note or Private Exchange Note delivered in exchange for an interest in the Global Note
shall, except as otherwise provided by Section 2.3(b), bear the restricted Notes legend set forth
in Exhibit A hereto.

     (c) The Holder of a Global Note shall be entitled to grant proxies and otherwise authorize any
Person, including Agent Members and Persons that may hold interests through Agent Members, to take

Company shall promptly make available to the Trustee a reasonable supply of Certificated Notes in
definitive, fully registered form without interest coupons.

Section 2. Exchange Offer

     (a) The Issuers shall (i) file a Registration Statement (the “Exchange Offer Registration
Statement”) within 90 days after the Issue Date with the Commission on an appropriate registration
form with respect to a registered offer (the “Exchange Offer”) to exchange any and all of the
Registrable Notes for a like aggregate principal amount of notes (including the guarantees with
respect thereto, the “Exchange Notes”) that are identical in all material respects to the Notes
(except that the Exchange Notes shall not contain terms with respect to transfer restrictions or
Liquidated Damages upon a Registration Default), (ii) use their reasonable best efforts to cause
the Exchange Offer Registration Statement to be declared effective under the Securities Act within
210 days after the Issue Date and (iii) use their reasonable best efforts to consummate the
Exchange Offer within 240 days after the Issue Date. Upon the Exchange Offer Registration Statement
being declared effective by the Commission, the Company will offer the Exchange Notes in exchange
for surrender of the Notes. The Company shall keep the Exchange Offer open for not less than 30
days (or longer if required by applicable law) after the date notice of the Exchange Offer is
mailed to Holders.

     Each Holder that participates in the Exchange Offer will be required to represent to the
Company in writing that at the time of the consummation of the Exchange Offer (i) any Exchange
Notes to be received by it will be acquired in the ordinary course of its business, (ii) it has no
arrangement or understanding with any Person to participate in the distribution (within the meaning
of the Securities Act) of the Exchange Notes in violation of the provisions of the Securities Act,
(iii) it is not an affiliate of the Issuer, as defined by rule 405 of the Securities Act, or if it
is an affiliate of the Issuer, it will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-

4

 

dealer, it is not engaged in, and does not intend to engage in, a distribution of Exchange
Notes and (v) if such Holder is a broker-dealer that will receive Exchange Notes for its own
account in exchange for Notes that were acquired as a result of market-making or other trading
activities, it will deliver a prospectus in connection with any resale of such Exchange Notes.

     (b) The Company and the Initial Purchaser acknowledge that the staff of the Commission has
taken the position that any broker-dealer that elects to exchange Notes that were acquired by such
broker-dealer for its own account as a result of market-making or other trading activities for
Exchange Notes in the Exchange Offer (a “Participating Broker-Dealer”) may be deemed to be an
“underwriter” within the meaning of the Securities Act and must deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of such Exchange Notes (other than
a resale of an unsold allotment resulting from the original offering of the Notes).

     The Company and the Initial Purchaser also acknowledge that the staff of the Commission has
taken the position that if the Prospectus contained in the Exchange Offer Registration Statement
includes a plan of distribution containing a statement to the above effect and the means by which
Participating Broker-Dealers may resell the Exchange Notes, without naming the Participating
Broker-Dealers or specifying the amount of Exchange Notes owned by them, such Prospectus may be
delivered by Participating Broker-Dealers to satisfy their prospectus delivery obligations under
the Securities Act in connection with resales of Exchange Notes for their own accounts, so long as
the Prospectus otherwise meets the requirements of the Securities Act.

     In light of the foregoing, if requested by a Participating Broker-Dealer (a “Requesting
Participating Broker-Dealer”), the Issuers agree to use their reasonable best efforts to keep the
Exchange Offer Registration Statement continuously effective for a period of up to 180 days after
the date on which the Exchange Registration Statement is declared effective, or such longer period
if extended pursuant to the last paragraph of Section 5 hereof (such period, the “Applicable
Period”), or such earlier date as all Requesting Participating Broker-Dealers shall have notified
the Company in writing that such Requesting Participating Broker-Dealers have resold all Exchange
Notes acquired in the Exchange Offer. The Company shall include a plan of distribution in such
Exchange Offer Registration Statement that meets the requirements set forth in the preceding
paragraph.

     If, prior to consummation of the Exchange Offer, any Holder holds any Notes acquired by it
that have, or that are reasonably likely to be determined to have, the status of an unsold
allotment in an initial distribution, or if any Holder is not entitled to participate in the
Exchange Offer, the Company upon the request of any such Holder shall simultaneously with the
delivery of the Exchange Notes in the Exchange Offer, issue and deliver to any such Holder, in
exchange (the “Private Exchange”) for such Notes held by any such Holder, a like principal amount
of notes (the “Private Exchange Notes”) of the Company that are identical in all material respects
to the Exchange Notes, except that the Private Exchange Notes may be subject to transfer
restrictions and bear a legend to such effect; provided, however, that the Issuers shall not be
required to effect a Private Exchange if in the written judgment of counsel for the Issuers or
counsel for the Initial Purchaser (copies of which are delivered to the Initial Purchaser or
Holders whose request is the subject of such judgments) such Private Exchange cannot be effected

5

 

without registration under the Securities Act. The Private Exchange Notes shall be issued
pursuant to the same indenture as the Exchange Notes and, if permitted by Standard & Poor’s CUSIP
Bureau, shall bear the same CUSIP number as the Exchange Notes.

     In connection with the Exchange Offer, the Company shall:

     (i) mail or cause to be mailed to each Holder entitled to participate in the Exchange
Offer a copy of the Prospectus forming part of the Exchange Offer Registration Statement,
together with an appropriate letter of transmittal and related documents;

     (ii) utilize the services of a depositary for the Exchange Offer with an address in the
Borough of Manhattan, The City of New York if any of the Notes is then in certificated form;

     (iii) permit Holders to withdraw tendered Notes at any time prior to the close of
business, New York time, on the last Business Day on which the Exchange Offer shall remain
open; and

     (iv) otherwise comply in all material respects with all applicable laws, rules and
regulations.

     As soon as practicable after the close of the Exchange Offer and the Private Exchange, if any,
the Company shall:

     (i) accept for exchange all Notes validly tendered and not validly withdrawn pursuant
to the Exchange Offer and the Private Exchange;

     (ii) deliver or cause to be delivered to the Trustee for cancellation all Notes in
certificated form so accepted for exchange; and

     (iii) cause the Trustee to deliver promptly to each Holder of Notes, Exchange Notes or
Private Exchange Notes, as the case may be, equal in principal amount to the Notes of such
Holder so accepted for exchange.

     The Exchange Offer and the Private Exchange shall not be subject to any conditions, other than
that (i) the Exchange Offer or Private Exchange, as the case may be, does not violate applicable
law or any applicable interpretation of the staff of the Commission, (ii) no action or proceeding
shall have been instituted or threatened in any court or by any governmental agency which might
materially impair the ability of the Company to proceed with the Exchange Offer or the Private
Exchange, and no material adverse development shall have occurred in any existing such action or
proceeding with respect to the Company and (iii) all governmental approvals shall have been
obtained, which approvals the Company deems necessary for the consummation of the Exchange Offer or
Private Exchange.

     The Exchange Notes and the Private Exchange Notes shall be issued under (i) the Indenture or
(ii) an indenture identical in all material respects to the Indenture (in either case, with such
changes as are necessary to comply with any requirements of the Commission to effect or maintain
the qualification thereof under the TIA) and which, in either case, has been qualified

6

 

under the TIA and shall provide that the Exchange Notes shall not be subject to the transfer
restrictions set forth in the Indenture. The Indenture or such indenture shall provide that the
Exchange Notes, the Private Exchange Notes and the Notes shall vote and consent together on all
matters as one class and that none of the Exchange Notes, the Private Exchange Notes or the Notes
will have the right to vote or consent as a separate class on any matter.

     (c) In the event that (i) any changes in law or the applicable interpretations of the staff of
the Commission do not permit the Issuers to effect the Exchange Offer, (ii) for any reason the
Exchange Offer is not consummated within 240 days after the Issue Date, (iii) any Holder is
prohibited by law or the applicable interpretations of the staff of the Commission from
participating in the Exchange Offer or does not receive Exchange Notes on the date of the exchange
that may be sold without restriction under state and federal securities laws (other than due solely
to the status of such Holder as an affiliate of any Issuer) or (iv) the Initial Purchaser so
requests with respect to Notes that have, or that are reasonably likely to be determined to have,
the status of unsold allotments in an initial distribution (each such event referred to in clauses
(i) through (iv) of this sentence, a “Shelf Filing Event”), then the Issuers shall use their
reasonable best efforts to, as promptly as practicable, file a Shelf Registration Statement
pursuant to Section 3 hereof.

Section 3. Shelf Registration Statement

     If at any time a Shelf Filing Event shall occur, then:

     (a) The Issuers shall file with the Commission a Registration Statement for an offering to be
made on a continuous basis pursuant to Rule 415 covering all of the Registrable Notes not exchanged
in the Exchange Offer, Private Exchange Notes and Exchange Notes as to which Section 2(c)(iv) is
applicable (the “Shelf Registration Statement”). The Issuers shall use their reasonable best
efforts to file with the Commission the Shelf Registration Statement as promptly as practicable.
The Shelf Registration Statement shall be on an appropriate form permitting registration of such
Registrable Notes for resale by Holders in the manner or manners designated by them (including,
without limitation, one or more underwritten offerings). The Company shall not permit any
securities other than the Registrable Notes to be included in the Shelf Registration Statement.

     (b) The Issuers shall use their reasonable best efforts (x) to cause the Shelf Registration
Statement to be declared effective under the Securities Act on or prior to the 240th day after the
Issue Date and (y) to use their reasonable best efforts to keep the Shelf Registration Statement
continuously effective under the Securities Act for the period ending on the date which is two
years from the Issue Date, subject to extension pursuant to the penultimate paragraph of Section 5
hereof (the “Effectiveness Period”), or such shorter period ending when all Registrable Notes
covered by the Shelf Registration Statement have been sold in the manner set forth and as
contemplated in the Shelf Registration Statement; provided, however, that (i) the Effectiveness
Period in respect of the Shelf Registration Statement shall be extended to the extent required to
permit dealers to comply with the applicable prospectus delivery requirements of Rule 174 under the
Securities Act and as otherwise provided herein and (ii) the Company may suspend the effectiveness
of the Shelf Registration Statement by written notice to the Holders solely as a result of the
filing of a post-effective amendment to the Shelf Registration Statement

7

 

to incorporate annual audited financial information with respect to the Company where such
post-effective amendment is not yet effective and needs to be declared effective to permit holders
to use the related Prospectus.

     (c) The Issuers agree to supplement or make amendments to the Shelf Registration Statement as
and when required by the rules, regulations or instructions applicable to the registration form
used for such Shelf Registration Statement or by the Securities Act or rules and regulations
thereunder for shelf registration, or if reasonably requested by the Holders of a majority in
aggregate principal amount of the Registrable Notes covered by such Registration Statement or by
any underwriter of such Registrable Notes.

Section 4. Liquidated Damages.

     (a) The Issuers and the Initial Purchaser agree that the Holders will suffer damages if the
Company fails to fulfill its obligations under Section 2 or Section 3 hereof and that it would not
be feasible to ascertain the extent of such damages with precision. Accordingly, the Company agrees
that if:

     (i) the Exchange Offer Registration Statement is not filed with the Commission on or
prior to the 90th day following the Issue Date,

     (ii) the Exchange Offer Registration Statement is not declared effective on or prior to
the 210th day following the Issue Date,

     (iii) the Exchange Offer is not consummated, or the Shelf Registration Statement is not
declared effective, on or prior to the 240th day following the Issue Date, or

     (iv) the Shelf Registration Statement is declared effective but thereafter ceases to be
effective or usable, except if the Shelf Registration Statement ceases to be effective or
usable as specifically permitted in the penultimate paragraph of Section 5 hereof

(each such event referred to in clauses (1) through (4) a “Registration Default”), liquidated
damages in the form of additional cash interest (“Liquidated Damages”) will accrue on the affected
Notes and the affected Exchange Notes, as applicable. The rate of Liquidated Damages will be 0.25%
per annum for the first 90-day period immediately following the occurrence of a Registration
Default, increasing by an additional 0.25% per annum with respect to each subsequent 90-day period
up to a maximum amount of additional interest of 1.00% per annum, from and including the date on
which any such Registration Default shall occur to, but excluding, the earlier of (1) the date on
which all Registration Defaults have been cured or (2) the date on which all the Notes and Exchange
Notes otherwise become freely transferable by Holders other than affiliates of the Issuer without
further registration under the Securities Act.

     Notwithstanding the foregoing, (1) the amount of Liquidated Damages payable shall not increase
because more than one Registration Default has occurred and is pending and (2) a Holder of Notes or
Exchange Notes who is not entitled to the benefits of the Shelf Registration Statement (i.e., such
Holder has not elected to include information) shall not be entitled to

8

 

Liquidated Damages with respect to a Registration Default that pertains to the Shelf
Registration Statement.

     (b) The Company shall notify the Trustee within one Business Day after each and every date on
which an event occurs in respect of which Liquidated Damages are required to be paid (an “Event
Date”). Any amounts of Liquidated Damages due pursuant to this Section 4 will be payable in
addition to any other interest payable from time to time with respect to the Registrable Notes and
the Exchange Notes in cash on each interest payment date to the holders of record for such interest
payment date, commencing with the first such interest payment date occurring after any such
Liquidated Damages commence to accrue. The amount of Liquidated Damages will be determined in a
manner consistent with the calculation of interest under the Indenture.

Section 5. Registration Procedures

     In connection with the filing of any Registration Statement pursuant to Section 2 or 3 hereof,
the Issuers shall effect such registrations to permit the sale of the securities covered thereby in
accordance with the intended method or methods of disposition thereof, and pursuant thereto and in
connection with any Registration Statement filed by the Issuers hereunder, the Issuers shall:

     (a) Prepare and file with the Commission the Registration Statement or Registration Statements
prescribed by Section 2 or 3 hereof, and use their reasonable best efforts to cause each such
Registration Statement to become effective and remain effective as provided herein; provided,
however, that, if (1) such filing is pursuant to Section 3 hereof or (2) a Prospectus contained in
the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be
delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period relating thereto, before filing any Registration Statement or
Prospectus or any amendments or supplements thereto, the Company shall furnish to and afford the
Holders of the Registrable Notes covered by such Registration Statement or each such Participating
Broker-Dealer, as the case may be, their counsel and the managing underwriters, if any, a
reasonable opportunity to review copies of all such documents (including copies of any documents to
be incorporated by reference therein and all exhibits thereto) proposed to be filed (in each case
at least five Business Days prior to such filing). The Company shall not file any Registration
Statement or Prospectus or any amendments or supplements thereto if the Holders of a majority in
aggregate principal amount of the Registrable Notes covered by such Registration Statement, or any
such Participating Broker-Dealer, as the case may be, their counsel, or the managing underwriters,
if any, shall reasonably object.

     (b) Prepare and file with the Commission such amendments and post-effective amendments to each
Shelf Registration Statement or Exchange Offer Registration Statement, as the case may be, as may
be necessary to keep such Registration Statement continuously effective for the Effectiveness
Period or the Applicable Period, as the case may be; cause the related Prospectus to be
supplemented by any Prospectus supplement required by applicable law, and as so supplemented to be
filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; and comply with the provisions of the Securities Act and the Exchange Act
applicable to each of them with respect to the disposition of all securities

9

 

covered by such Registration Statement as so amended or in such Prospectus as so supplemented
and with respect to the subsequent resale of any securities being sold by a Participating
Broker-Dealer covered by any such Prospectus, in each case, in accordance with the intended methods
of distribution set forth in such Registration Statement or Prospectus, as so amended.

     (c) If (1) a Shelf Registration Statement is filed pursuant to Section 3 hereof or (2) a
Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2
hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who
seeks to sell Exchange Notes during the Applicable Period relating thereto, notify the selling
Holders of Registrable Notes, or each such Participating Broker-Dealer, as the case may be, their
counsel and the managing underwriters, if any, as promptly as possible and, if requested by any
such Person, confirm such notice in writing (i) when a Prospectus or any Prospectus supplement or
post-effective amendment has been filed and, with respect to a Registration Statement or any
post-effective amendment, when the same has become effective under the Securities Act (including in
such notice a written statement that any Holder may, upon request, obtain, at the sole expense of
the Company, one conformed copy of such Registration Statement or post-effective amendment
including financial statements and schedules, documents incorporated or deemed to be incorporated
by reference and exhibits), (ii) of the issuance by the Commission of any stop order suspending the
effectiveness of a Registration Statement or of any order preventing or suspending the use of any
preliminary prospectus or the initiation of any proceedings for that purpose, (iii) if at any time
when a Prospectus is required by the Securities Act to be delivered in connection with sales of the
Registrable Notes or resales of Exchange Notes by Participating Broker-Dealers the representations
and warranties of the Issuers contained in any agreement (including any underwriting agreement)
contemplated by Section 5(m) hereof cease to be true and correct in all material respects, (iv) of
the receipt by any of the Issuers of any notification with respect to the suspension of the
qualification or exemption from qualification of a Registration Statement or any of the Registrable
Notes or the Exchange Notes for offer or sale in any jurisdiction, or the initiation or threatening
of any proceeding for such purpose, (v) of the happening of any event, the existence of any
condition or any information becoming known to the Company that makes any statement made in such
Registration Statement or related Prospectus or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that requires the making of any
changes in or amendments or supplements to such Registration Statement, Prospectus or documents so
that, in the case of the Registration Statement, it will not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein or necessary to make
the statements therein not misleading, and that in the case of the Prospectus, it will not contain
any untrue statement of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in the light of the circumstances under which
they were made, not misleading and (vi) of the Company’s determination that a post-effective
amendment to a Registration Statement would be appropriate.

     (d) If (1) a Shelf Registration Statement is filed pursuant to Section 3 hereof, or (2) a
Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2
hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who
seeks to sell Exchange Notes during the Applicable Period, use their reasonable best efforts to
prevent the issuance of any order suspending the effectiveness of a Registration Statement or of
any order preventing or suspending the use of a Prospectus or suspending the qualification (or

10

 

exemption from qualification) of any of the Registrable Notes or the Exchange Notes, as the
case may be, for sale in any jurisdiction and, if any such order is issued, to use their reasonable
best efforts to obtain the withdrawal of any such order at the earliest practicable moment.

     (e) If (1) a Shelf Registration Statement is filed pursuant to Section 3 hereof or (2) a
Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2
hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who
seeks to sell Exchange Notes during the Applicable Period and, if requested by the managing
underwriter or underwriters (if any), the Holders of a majority in aggregate principal amount of
the Registrable Notes covered by such Registration Statement or any Participating Broker-Dealer, as
the case may be, (i) promptly incorporate in such Registration Statement or Prospectus, a
prospectus supplement or post-effective amendment such information as the managing underwriter or
underwriters (if any), such Holders or any Participating Broker-Dealer, as the case may be (based
upon advice of counsel), determine is reasonably necessary to be included therein and (ii) make all
required filings of such prospectus supplement or such post-effective amendment as soon as
practicable after the Company has received notification of the matters to be incorporated in such
prospectus supplement or post-effective amendment; provided, however, that the Issuers shall not be
required to take any action hereunder that would, in the written opinion of counsel to the Company,
violate applicable laws.

     (f) If (1) a Shelf Registration Statement is filed pursuant to Section 3 hereof or (2) a
Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2
hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who
seeks to sell Exchange Notes during the Applicable Period, furnish to each selling Holder of
Registrable Notes or each such Participating Broker-Dealer, as the case may be, who so requests,
their counsel and each managing underwriter, if any, at the sole expense of the Company, one
conformed copy of the Registration Statement or Registration Statements and each post-effective
amendment thereto, including financial statements and schedules, and, if requested, all documents
incorporated or deemed to be incorporated therein by reference and all exhibits.

     (g) If (1) a Shelf Registration Statement is filed pursuant to Section 3 hereof or (2) a
Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2
hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who
seeks to sell Exchange Notes during the Applicable Period, deliver to each selling Holder of
Registrable Notes or each such Participating Broker-Dealer, as the case may be, their respective
counsel and the underwriters, if any, at the sole expense of the Company, as many copies of the
Prospectus or Prospectuses (including each form of preliminary prospectus) and each amendment or
supplement thereto and any documents incorporated by reference therein as such Persons may
reasonably request; and, subject to the last paragraph of this Section 5, the Issuers hereby
consent to the use of such Prospectus and each amendment or supplement thereto by each of the
selling Holders of Registrable Notes or each such Participating Broker-Dealer, as the case may be,
and the underwriters or agents, if any, and dealers (if any), in connection with the offering and
sale of the Registrable Notes or the sale by Participating Broker-Dealers of the Exchange Notes.

     (h) Prior to any public offering of Registrable Notes or Exchange Notes or any delivery of a
Prospectus contained in the Exchange Offer Registration Statement by any

11

 

Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, use
their reasonable best efforts to register or qualify, and to cooperate with the selling Holders of
Registrable Notes or each such Participating Broker-Dealer, as the case may be, the managing
underwriter or underwriters, if any, and their respective counsel in connection with the
registration or qualification (or exemption from such registration or qualification) of such
Registrable Notes or Exchange Notes, as the case may be, for offer and sale under the securities or
Blue Sky laws of such jurisdictions within the United States as any selling Holder, Participating
Broker-Dealer, or the managing underwriter or underwriters reasonably request; provided, however,
that where Exchange Notes or Registrable Notes are offered other than through an underwritten
offering, the Company agrees to cause the Company’s counsel to perform Blue Sky investigations and
file registrations and qualifications required to be filed pursuant to this Section 5(h); keep each
such registration or qualification (or exemption therefrom) effective during the period such
Registration Statement is required to be kept effective and do any and all other acts or things
reasonably necessary or advisable to enable the disposition in such jurisdictions of such Exchange
Notes or Registrable Notes covered by the applicable Registration Statement; provided, however,
that no Issuer shall be required to (A) qualify generally to do business in any jurisdiction where
it is not then so qualified, (B) take any action that would subject it to general service of
process in any such jurisdiction where it is not then so subject or (C) subject itself to taxation
in excess of a nominal dollar amount in any such jurisdiction where it is not then so subject.

     (i) If a Shelf Registration Statement is filed pursuant to Section 3 hereof, cooperate with
the selling Holders of Registrable Notes and the managing underwriter or underwriters, if any, to
facilitate the timely preparation and delivery of certificates representing Registrable Notes to be
sold, which certificates shall not bear any restrictive legends and shall be in a form eligible for
deposit with The Depository Trust Company; and enable such Registrable Notes to be in such
denominations and registered in such names as the managing underwriter or underwriters, if any, or
selling Holders may request at least two Business Days prior to any sale of such Registrable Notes
or Exchange Notes.

     (j) Use their reasonable best efforts to cause the Registrable Notes or Exchange Notes covered
by any Registration Statement to be registered with or approved by such other governmental agencies
or authorities as may be reasonably necessary to enable the seller or sellers thereof or the
underwriter or underwriters, if any, to consummate the disposition of such Registrable Notes or
Exchange Notes, except as may be required solely as a consequence of the nature of such selling
Holder’s business, in which case the Company will cooperate in all reasonable respects with the
filing of such Registration Statement and the granting of such approvals.

     (k) If (1) a Shelf Registration Statement is filed pursuant to Section 3 hereof or (2) a
Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2
hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who
seeks to sell Exchange Notes during the Applicable Period, upon the occurrence of any event
contemplated by Section 5(c)(v) or 5(c)(vi) hereof, as promptly as practicable prepare and (subject
to Section 5(a) hereof and the penultimate paragraph of this Section 5) file with the Commission,
at the sole expense of the Company, a supplement or post-effective amendment to the Registration
Statement or a supplement to the related Prospectus or any document

12

 

incorporated or deemed to be incorporated therein by reference, or file any other required
document so that, as thereafter delivered to the purchasers of the Registrable Notes being sold
thereunder or to the purchasers of the Exchange Notes to whom such Prospectus will be delivered by
a Participating Broker-Dealer, any such Prospectus will not contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances under which they were made, not
misleading.

     (l) Promptly after the consummation of the Exchange Offer or prior to the effective date of
the first Shelf Registration Statement relating to the Registrable Notes, as the case may be, (i)
provide the Trustee with certificates for the Exchange Notes or the Registrable Notes, as the case
may be, in a form eligible for deposit with The Depository Trust Company and (ii) provide a CUSIP
number for the Exchange Notes or the Registrable Notes, as the case may be.

     (m) In connection with any underwritten offering of Registrable Notes pursuant to a Shelf
Registration Statement, enter into an underwriting agreement as is customary in underwritten
offerings of debt securities similar to the Notes and take all such other actions as are reasonably
requested by the managing underwriter or underwriters in order to expedite or facilitate the
registration or the disposition of such Registrable Notes and, in such connection, (i) make such
representations and warranties to, and covenants with, the underwriters with respect to the
business of the Company and its subsidiaries (including any acquired business, properties or
entity, if applicable) and the Registration Statement, Prospectus and documents, if any,
incorporated or deemed to be incorporated by reference therein, in each case, as are customarily
made by issuers to underwriters in underwritten offerings of debt securities similar to the Notes,
and confirm the same in writing if and when requested; (ii) use their reasonable best efforts to
obtain the written opinions of counsel to the Company and written updates thereof in form, scope
and substance reasonably satisfactory to the managing underwriter or underwriters, addressed to the
underwriters covering the matters customarily covered in opinions requested in underwritten
offerings and such other matters as may be reasonably requested by the managing underwriter or
underwriters; (iii) use their reasonable best efforts to obtain “cold comfort” letters and updates
thereof in form, scope and substance reasonably satisfactory to the managing underwriter or
underwriters from the independent certified public accountants of the Company (and, if necessary,
any other independent certified public accountants of any subsidiary of the Company or of any
business acquired by the Company for which financial statements and financial data are, or are
required to be, included or incorporated by reference in the Registration Statement), addressed to
each of the underwriters, such letters to be in customary form and covering matters of the type
customarily covered in “cold comfort” letters in connection with underwritten offerings; and (iv)
if an underwriting agreement is entered into, the same shall contain indemnification provisions and
procedures no less favorable than those set forth in Section 7 hereof (or such other provisions and
procedures acceptable to Holders of a majority in aggregate principal amount of Registrable Notes
covered by such Registration Statement and the managing underwriter or underwriters or agents) with
respect to all parties to be indemnified pursuant to said Section. The above shall be done at each
closing under such underwriting agreement, or as and to the extent required thereunder.

13

 

     (n) If (1) a Shelf Registration Statement is filed pursuant to Section 3 hereof or (2) a
Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2
hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who
seeks to sell Exchange Notes during the Applicable Period, make available for inspection by any
selling Holder of such Registrable Notes being sold or each such Participating Broker-Dealer, as
the case may be, any underwriter participating in any such disposition of Registrable Notes, if
any, and any attorney, accountant or other agent retained by any such selling Holder or each such
Participating Broker-Dealer, as the case may be, or underwriter (collectively, the “Inspectors”),
at the offices where normally kept, during reasonable business hours, all financial and other
records, pertinent corporate documents and instruments of the Company and its subsidiaries
(collectively, the “Records”) as shall be reasonably necessary to enable them to exercise any
applicable due diligence responsibilities, and cause the officers, directors and employees of the
Company and its subsidiaries to supply all information reasonably requested by any such Inspector
in connection with such Registration Statement and Prospectus. Each Inspector shall agree in
writing that it will not disclose any records that the Company determines, in good faith, to be
confidential and that it notifies the Inspectors in writing are confidential unless (i) the
disclosure of such Records is necessary to avoid or correct a misstatement or omission in such
Registration Statement or Prospectus, (ii) the release of such Records is ordered pursuant to a
subpoena or other order from a court of competent jurisdiction, (iii) disclosure of such
information is necessary or advisable in connection with any action, claim, suit or proceeding,
directly or indirectly, involving or potentially involving such Inspector and arising out of, based
upon, relating to, or involving this Agreement or the Purchase Agreement, or any transactions
contemplated hereby or thereby or arising hereunder or thereunder or (iv) the information in such
Records has been made generally available to the public; provided, however, that such Inspector
shall take such actions as are reasonably necessary to protect the confidentiality of such
information (if practicable) to the extent such action is otherwise not inconsistent with, an
impairment of or in derogation of the rights and interests of the Holder or any Inspector.

     (o) Provide an indenture trustee for the Registrable Notes or the Exchange Notes, as the case
may be, and cause the Indenture or the trust indenture provided for in Section 2(a) hereof to be
qualified under the TIA not later than the effective date of the Exchange Offer or the first
Registration Statement relating to the Registrable Notes; and in connection therewith, cooperate
with the trustee under any such indenture and the Holders of the Registrable Notes or Exchange
Notes, as applicable, to effect such changes to such indenture as may be required for such
indenture to be so qualified in accordance with the terms of the TIA; and execute, and use their
reasonable best efforts to cause such trustee to execute, all documents as may be required to
effect such changes, and all other forms and documents required to be filed with the Commission to
enable such indenture to be so qualified in a timely manner.

     (p) Comply with all applicable rules and regulations of the Commission and make generally
available to the Company’s securityholders earnings statements satisfying the provisions of Section
11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the
Securities Act) no later than 45 days after the end of any 12-month period (or 90 days after the
end of any 12-month period if such period is a fiscal year) (i) commencing at the end of any fiscal
quarter in which Registrable Notes or Exchange Notes are sold to underwriters in a firm commitment
or best efforts underwritten offering and (ii) if not sold to

14

 

underwriters in such an offering, commencing on the first day of the first fiscal quarter of
the Company after the effective date of a Registration Statement, which statements shall cover said
12-month periods.

     (q) Upon the request of a Holder, upon consummation of the Exchange Offer or a Private
Exchange, use their reasonable best efforts to obtain an opinion of counsel to the Company, in a
form customary for underwritten transactions, addressed to the Trustee for the benefit of all
Holders of Registrable Notes participating in the Exchange Offer or the Private Exchange, as the
case may be, that the Exchange Notes or Private Exchange Notes, as the case may be, and the related
indenture constitute legal, valid and binding obligations of the Company, enforceable against the
Company in accordance with its respective terms, subject to customary exceptions and
qualifications.

     (r) If the Exchange Offer or a Private Exchange is to be consummated, upon delivery of the
Registrable Notes by Holders to the Company (or to such other Person as directed by the Company) in
exchange for the Exchange Notes or the Private Exchange Notes, as the case may be, mark, or cause
to be marked, on such Registrable Notes that such Registrable Notes are being cancelled in exchange
for the Exchange Notes or the Private Exchange Notes, as the case may be; in no event shall such
Registrable Notes be marked as paid or otherwise satisfied.

     (s) Cooperate with each seller of Registrable Notes covered by any Registration Statement and
each underwriter, if any, participating in the disposition of such Registrable Notes and their
respective counsel in connection with any filings required to be made with the National Association
of Securities Dealers, Inc. (the “NASD”).

     (t) Use their reasonable best efforts to take all other steps necessary or advisable to effect
the registration of the Exchange Notes and/or Registrable Notes covered by a Registration Statement
contemplated hereby.

     The Company may require each seller of Registrable Notes or Exchange Notes as to which any
registration is being effected to furnish to the Company such information regarding such seller and
the distribution of such Registrable Notes or Exchange Notes as the Company may, from time to time,
reasonably request. The Company may exclude from such registration the Registrable Notes or
Exchange Notes of any seller so long as such seller fails to furnish such information within a
reasonable time after receiving such request. Each seller as to which any Shelf Registration
Statement is being effected agrees to furnish promptly to the Company all information required to
be disclosed in order to make any information previously furnished to the Company by such seller
not materially misleading.

     If any such Registration Statement refers to any Holder by name or otherwise as the holder of
any securities of the Company, then such Holder shall have the right to require (i) the insertion
therein of language, in form and substance reasonably satisfactory to such Holder, to the effect
that the holding by such Holder of such securities is not to be construed as a recommendation by
such Holder of the investment quality of the securities covered thereby and that such holding does
not imply that such Holder will assist in meeting any future financial requirements of the Company
or (ii) in the event that such reference to such Holder by name or otherwise is not required by the
Securities Act or any similar federal statute then in force, the

15

 

deletion of the reference to such Holder in any amendment or supplement to the Registration
Statement filed or prepared subsequent to the time that such reference ceases to be required.

     Each Holder of Registrable Notes and each Participating Broker-Dealer agrees by acquisition of
such Registrable Notes or Exchange Notes that, upon actual receipt of any notice from the Company
(x) of the happening of any event of the kind described in Section 5(c)(ii), 5(c)(iii), 5(c)(iv) or
5(c)(v) hereof or (y) that the Board of Directors of the Company (the “Board of Directors”) has
resolved that the Company has a bona fide business purpose for doing so, then the Company may delay
the filing or the effectiveness of the Exchange Offer Registration Statement or the Shelf
Registration Statement (if not then filed or effective, as applicable) and shall not be required to
maintain the effectiveness thereof or amend or supplement the Exchange Offer Registration Statement
or the Shelf Registration Statement, in all cases, for a period (a “Delay Period”) expiring upon
the earlier to occur of (i) in the case of the immediately preceding clause (x), such Holder’s or
Participating Broker-Dealer’s receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 5(k) hereof or until it is advised in writing (the “Advice”) by the Company
that the use of the applicable Prospectus may be resumed, and has received copies of any amendments
or supplements thereto or (ii) in the case of the immediately preceding clause (y), the date which
is the earlier of (A) the date on which such business purpose ceases to interfere with the
Company’s obligations to file or maintain the effectiveness of any such Registration Statement
pursuant to this Agreement or (B) 60 days after the Company notifies the Holders of such good faith
determination. There shall not be more than 90 days of Delay Periods during any 12-month period.
Each of the Effectiveness Period and the Applicable Period, if applicable, shall be extended by the
number of days during any Delay Period. Any Delay Period will not alter the obligations of the
Company to pay Liquidated Damages under the circumstances set forth in Section 4 hereof.

     In the event of any Delay Period pursuant to clause (y) of the preceding paragraph, notice
shall be given as soon as practicable after the Board of Directors makes such a determination of
the need for a Delay Period and shall state, to the extent practicable, an estimate of the duration
of such Delay Period and shall advise the recipient thereof of the agreement of such Holder
provided in the next succeeding sentence. Each Holder, by his acceptance of any Registrable Note,
agrees that during any Delay Period, each Holder will discontinue disposition of such Notes or
Exchange Notes covered by such Registration Statement or Prospectus or Exchange Notes to be sold by
such Holder or Participating Broker-Dealer, as the case may be.

Section 6. Registration Expenses

     All fees and expenses incident to the performance of or compliance with this Agreement by the
Issuers shall be borne by the Issuers, whether or not the Exchange Offer Registration Statement or

without limitation, (A) fees with respect to filings required to be made with the NASD in

16

 

case of an Exchange Offer, or (y) as provided in Section 5(h) hereof, in the case of a Shelf
Registration Statement or in the case of Exchange Notes to be sold by a Participating Broker-Dealer
during the Applicable Period)), (ii) printing expenses, including, without limitation, expenses of
printing prospectuses if the printing of prospectuses is requested by the managing underwriter or

of all independent certified public accountants referred to in Section 5(m)(iii) hereof (including,
without limitation, the expenses of any special audit and “cold comfort” letters required by or

in order to comply with this Agreement. Notwithstanding the foregoing or anything to the contrary,
each Holder shall pay all underwriting discounts and commissions of any underwriters with respect
to any Registrable Notes sold by or on behalf of it.

Section 7. Indemnification

     (a) Each Issuer, jointly and severally, agrees to indemnify and hold harmless each Holder of
Registrable Notes and each Participating Broker-Dealer selling Exchange Notes during the Applicable
Period, each Person, if any, who controls any such Person within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act, the agents, employees, officers and directors
of each Holder and each such Participating Broker-Dealer and the agents, employees, officers and
directors of any such controlling Person (each, a “Participant”) from and against any and all
losses, liabilities, claims, damages and expenses whatsoever (including, but not limited to,
reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in
investigating, preparing or defending against any litigation, commenced or threatened, or any claim
whatsoever, and any and all reasonable amounts paid in settlement of any claim or litigation)
(collectively, “Losses”) to which they or any of them may become subject under the Securities Act,
the Exchange Act or otherwise insofar as such Losses (or actions in respect thereof) arise out of
or are based upon any untrue statement or alleged untrue statement of a material fact contained in
any Registration Statement (or any amendment thereto) or Prospectus (as amended or supplemented if
the Company shall have furnished any amendments or supplements thereto) or any preliminary
prospectus, or caused by, arising out of or based upon any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the statements therein,
in the case of the Prospectus, in the light of the circumstances under which they were made, not
misleading, provided that the foregoing indemnity shall not be available to any Participant insofar
as such Losses are caused by any untrue statement or omission or alleged untrue statement or
omission made in reliance

17

 

upon and in conformity with information relating to such Participant furnished to the Company
in writing by or on behalf of such Participant expressly for use therein. This indemnity agreement
will be in addition to any liability that the Issuers may otherwise have, including, but not
limited to, liability under this Agreement.

     (b) Each Participant agrees, severally and not jointly, to indemnify and hold harmless each
Issuer, each Person, if any, who controls any Issuer within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act, and each of their respective agents,
employees, officers and directors and the agents, employees, officers and directors of any such
controlling Person from and against any Losses to which they or any of them may become subject
under the Securities Act, the Exchange Act or otherwise insofar as such Losses (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of
a material fact contained in any Registration Statement (or any amendment thereto) or Prospectus
(as amended or supplemented if the Company shall have furnished any amendments or supplements
thereto) or any preliminary prospectus, or caused by, arising out of or based upon any omission or
alleged omission to state therein a material fact required to be stated therein or necessary to
make the statements therein, in the case of the Prospectus, in the light of the circumstances under
which they were made, not misleading, in each case to the extent, but only to the extent, that any
such Loss arises out of or is based upon any untrue statement or alleged untrue statement or
omission or alleged omission made in reliance upon and in conformity with information relating to
such Participant furnished in writing to the Company by or on behalf of such Participant expressly
for use therein.

     (c) Promptly after receipt by an indemnified party under subsection 7(a) or 7(b) above of
notice of the commencement of any action, suit or proceeding (collectively, an “action”), such
indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party
under such subsection, notify each party against whom indemnification is to be sought in writing of
the commencement of such action (but the failure so to notify an indemnifying party shall not
relieve such indemnifying party from any liability that it may have under this Section 7 except to
the extent that it has been prejudiced in any material respect by such failure). In case any such
action is brought against any indemnified party, and it notifies an indemnifying party of the
commencement of such action, the indemnifying party will be entitled to participate in such action,
and to the extent it may elect by written notice delivered to the indemnified party promptly after
receiving the aforesaid notice from such indemnified party, to assume the defense of such action
with counsel satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified
party or parties shall have the right to employ its or their own counsel in any such action, but
the reasonable fees and expenses of such counsel shall be at the expense of such indemnified party
or parties unless (i) the employment of such counsel shall have been authorized in writing by the
indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties
shall not have employed counsel to take charge of the defense of such action within a reasonable
time after notice of commencement of the action, or (iii) the named parties to such action
(including any impleaded parties) include such indemnified party and the indemnifying party or
parties (or such indemnifying parties have assumed the defense of such action), and such
indemnified party or parties shall have reasonably concluded that there may be defenses available
to it or them that are different from or additional to those available to one or all of the
indemnifying parties (in which case the indemnifying parties shall not have the right to direct the
defense of such action on behalf of the indemnified

18

 

party or parties), in any of which events such reasonable fees and expenses of counsel shall
be borne by the indemnifying parties. In no event shall the indemnifying party be liable for the
fees and expenses of more than one counsel (together with appropriate local counsel) at any time
for all indemnified parties in connection with any one action or separate but substantially similar
or related actions arising in the same jurisdiction out of the same general allegations or
circumstances. An indemnifying party shall not be liable for any settlement of any claim or action
effected without its written consent, which consent may not be unreasonably withheld.
Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of counsel as
contemplated by paragraph (a) or (b) of this Section 7, then the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected without its written consent if (i)
such settlement is entered into more than 45 business days after receipt by such indemnifying party
of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified
party in accordance with such request prior to the date of such settlement and (iii) such
indemnified party shall have given the indemnifying party at least 45 days prior notice of its
intention to settle. No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened proceeding in respect of
which any indemnified party is or could have been a party and indemnity could have been sought
hereunder by such indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter of such proceeding.

     (d) In order to provide for contribution in circumstances in which the indemnification
provided for in this Section 7 is for any reason held to be unavailable from the indemnifying
party, or is insufficient to hold harmless a party indemnified under this Section 7, each
indemnifying party shall contribute to the amount paid or payable by such indemnified party as a
result of such aggregate Losses (i) in such proportion as is appropriate to reflect the relative
benefits received by each indemnifying party, on the one hand, and each indemnified party, on the
other hand, from the sale of the Notes to the Initial Purchaser or the resale of the Registrable
Notes by such Holder, as applicable, or (ii) if such allocation is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits referred to above
but also the relative fault of each indemnified party, on the one hand, and each indemnifying
party, on the other hand, in connection with the statements or omissions that resulted in such
Losses, as well as any other relevant equitable considerations. The relative benefits received by
the Issuers, on the one hand, and each Participant, on the other hand, shall be deemed to be in the
same proportion as (x) the total proceeds from the sale of the Notes to the Initial Purchaser (net
of discounts and commissions but before deducting expenses) received by the Issuers are to (y) the
total net profit received by such Participant in connection with the sale of the Registrable Notes.
The relative fault of the parties shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or alleged omission to
state a material fact relates to information supplied by the Issuers or such Participant and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission or alleged statement or omission.

     (e) The parties agree that it would not be just and equitable if contribution pursuant to this
Section 7 were determined by pro rata allocation or by any other method of allocation that does not
take into account the equitable considerations referred to above. Notwithstanding the provisions of
this Section 7, (i) in no case shall any Participant be required to contribute any

19

 

amount in excess of the amount by which the net profit received by such Participant in
connection with the sale of the Registrable Notes exceeds the amount of any damages that such
Participant has otherwise been required to pay by reason of any untrue or alleged untrue statement
or omission or alleged omission and (ii) no person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. Any party entitled to contribution will, promptly
after receipt of notice of commencement of any action against such party in respect of which a
claim for contribution may be made against another party or parties under this Section 7, notify
such party or parties from whom contribution may be sought, but the omission to so notify such
party or parties shall not relieve the party or parties from whom contribution may be sought from
any obligation it or they may have under this Section 7 or otherwise, except to the extent that it
has been prejudiced in any material respect by such failure; provided, however, that no additional
notice shall be required with respect to any action for which notice has been given under this
Section 7 for purposes of indemnification. Anything in this section to the contrary
notwithstanding, no party shall be liable for contribution with respect to any action or claim
settled without its written consent, provided, that such written consent was not unreasonably
withheld.

Section 8. Rules 144 and 144A

     The Company covenants that it will file the reports required to be filed by it under the
Securities Act and the Exchange Act and the rules and regulations adopted by the Commission
thereunder in a timely manner in accordance with the requirements of the Securities Act and the
Exchange Act and, if at any time the Company is not required to file such reports, it will, upon
the request of any Holder or beneficial owner of Registrable Notes, make available such information
necessary to permit sales pursuant to Rule 144A under the Securities Act. The Issuers further
covenant that they will take such further action as any Holder of Registrable Notes may reasonably
request from time to time to enable such Holder to sell Registrable Notes without registration
under the Securities Act within the limitation of the exemptions provided by (a) Rule 144(k) and
Rule 144A under the Securities Act, as such Rules may be amended from time to time, or (b) any
similar rule or regulation hereafter adopted by the Commission.

Section 9. Underwritten Registrations

     If any of the Registrable Notes covered by any Shelf Registration Statement are to be sold in
an underwritten offering, the investment banker or investment bankers and manager or managers that
will manage the offering will be selected by the Holders of a majority in aggregate principal
amount of such Registrable Notes included in such offering and shall be reasonably acceptable to
the Company.

     No Holder of Registrable Notes may participate in any underwritten registration hereunder if
such Holder does not (a) agree to sell such Holder’s Registrable Notes on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements
and (b) complete and execute all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents required under the terms of such underwriting arrangements.

20

 

Section 10. Miscellaneous

     (a) No Inconsistent Agreements. The Issuers have not, as of the date hereof, and shall not,
after the date of this Agreement, enter into any agreement with respect to any of their securities
that is inconsistent with the rights granted to the Holders of Registrable Notes in this Agreement
or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do
not conflict with and are not inconsistent with, in any material respect, the rights granted to the
holders of any of the Issuers’ other issued and outstanding securities under any such agreements.
The Issuers have not entered and will not enter into any agreement with respect to any of their
securities which will grant to any Person piggy-back registration rights with respect to any
Registration Statement.

     (b) Adjustments Affecting Registrable Notes. The Company shall not, directly or indirectly,
take any action with respect to the Registrable Notes as a class that would adversely affect the
ability of the Holders of Registrable Notes to include such Registrable Notes in a registration
undertaken pursuant to this Agreement.

     (c) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof may not be given
except pursuant to a written agreement duly signed and delivered by (I) the Company (on behalf of
all Issuers) and (II)(A) the Holders of not less than a majority in aggregate principal amount of
the then outstanding Registrable Notes and (B) in circumstances that would adversely affect the
Participating Broker-Dealers, the Participating Broker-Dealers holding not less than a majority in
aggregate principal amount of the Exchange Notes held by all Participating Broker-Dealers;
provided, however, that Section 7 and this Section 10(c) may not be amended, modified or
supplemented, and the amount of any Liquidated Damages payable hereunder may not be reduced and the
due date thereof may not be extended, except in any case pursuant to a written agreement duly
signed and delivered by each Holder and each Participating Broker-Dealer (including any Person who
was a Holder or Participating Broker-Dealer of Registrable Notes or Exchange Notes, as the case may
be, disposed of pursuant to any Registration Statement) affected by any such amendment,
modification, supplement, waiver or consent. Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates exclusively to the rights
of Holders of Registrable Notes whose securities are being sold pursuant to a Registration
Statement and that does not directly or indirectly affect, impair, limit or compromise the rights
of other Holders of Registrable Notes may be given by Holders of at least a majority in aggregate
principal amount of the Registrable Notes being sold pursuant to such Registration Statement.

     (d) Notices. All notices and other communications (including, without limitation, any notices
or other communications to the Trustee) provided for or permitted hereunder shall be made in
writing by hand-delivery, registered first-class mail, next-day air courier or facsimile:

COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) WITH RESPECT TO ANY CLAIM,
COUNTER-CLAIM OR ACTION ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY.

     (j) Severability. If any term, provision, covenant or restriction of this Agreement is held by
a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of
the terms, provisions, covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use
their best efforts to find and employ an alternative means to achieve the same or substantially the
same result as that contemplated by such term, provision, covenant or restriction. It is hereby
stipulated and declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

     (k) Securities Held by the Company or Its Affiliates. Whenever the consent or approval of
Holders of a specified percentage of Registrable Notes is required hereunder, Registrable Notes
held by the Company or any of its affiliates (as such term is defined in Rule 405 under the
Securities Act) shall not be counted in determining whether such consent or approval was given by
the Holders of such required percentage.

     (l) Third-Party Beneficiaries. Holders and beneficial owners of Registrable Notes and
Participating Broker-Dealers are intended third-party beneficiaries of this Agreement, and this

as, a third-party beneficiary of this Agreement.

     (m) Attorneys’ Fees. As between the parties to this Agreement, in any action or proceeding
brought to enforce any provision of this Agreement, or where any provision hereof is validly
asserted as a defense, the successful party shall be entitled to recover reasonable attorneys’ fees
actually incurred in addition to its costs and expenses and any other available remedy.

     (n) Entire Agreement. This Agreement, together with the Purchase Agreement and the Indenture,
is intended by the parties as a final and exclusive statement of the agreement and understanding of
the parties hereto in respect of the subject matter contained herein and therein and any and all
prior oral or written agreements, representations, or warranties, contracts, understandings,
correspondence, conversations and memoranda between the Holders on the one hand and the Company on
the other, or between or among any agents, representatives, parents,
subsidiaries, affiliates, predecessors in interest or successors in interest with respect to
the subject matter hereof and thereof are merged herein and replaced hereby.
