the form of Exhibits A1 or A2 attached hereto (including the Global Note Legend
thereon and the "Schedule of Exchanges of Interests in the Global Note" attached
thereto). Notes issued in definitive form will be substantially in the form of
Exhibit A1 attached hereto (but without the Global Note Legend thereon and
without the "Schedule of Exchanges of Interests in the Global Note" attached
thereto). Each Global Note will represent such of the outstanding Notes as will
be specified therein and each shall provide that it represents the aggregate
principal amount of outstanding Notes from time to time endorsed thereon and
that the aggregate principal amount of outstanding Notes represented thereby may
from time to time be reduced or increased, as appropriate, to reflect exchanges,
transfers and redemptions. Any endorsement of a Global Note to reflect the
amount, or any increase or decrease in the amount, of outstanding Notes
represented thereby will be made by the Trustee or the Custodian, at the
direction of the Trustee, in accordance with instructions given by the Holder
thereof as required by Section 2.06 hereof.

         (c) Temporary Global Notes. Notes offered and sold to Non-U.S. Persons
in reliance on Regulation S will be issued initially in the form of the
Regulation S Temporary Global Note, which will be deposited on behalf of the
purchasers of the Notes represented thereby with the Trustee, at its Dallas,
Texas office, as custodian for the Depositary, and registered in the name of the
Depositary or the nominee of the Depositary for the accounts of designated
agents holding on behalf of Euroclear or Clearstream Bank, duly executed by the
Company and authenticated by the Trustee as hereinafter provided. The Restricted
Period will be terminated upon the receipt by the Trustee of:

                  (1) a written certificate from the Depositary, together with
         copies of certificates from Euroclear and Clearstream Bank certifying
         that they have received certification of non-United States beneficial
         ownership of 100% of the aggregate principal amount of the Regulation S
         Temporary Global Note (except to the extent of any beneficial owners
         thereof who acquired an interest therein during the Restricted Period
         pursuant to another exemption from registration under the Securities
         Act and who will take delivery of a beneficial ownership interest in a
         144A Global Note or an IAI Global Note bearing a Private Placement
         Legend, all as contemplated by Section 2.06(b) hereof); and


                                       25

                  (2) an Officers' Certificate from the Company, as required
         pursuant to Section 12.04 hereof;

         Following the termination of the Restricted Period, beneficial
interests in the Regulation S Temporary Global Note will be exchanged for
beneficial interests in Regulation S Permanent Global Notes pursuant to the
Applicable Procedures. Simultaneously with the authentication of Regulation S
Permanent Global Notes, the Trustee will cancel the Regulation S Temporary
Global Note. The aggregate principal amount of the Regulation S Temporary Global
Note and the Regulation S Permanent Global Notes may from time to time be
increased or decreased by adjustments made on the records of the Trustee and the
Depositary or its nominee, as the case may be, in connection with transfers of
interest as hereinafter provided.

         (d) Euroclear and Clearstream Procedures Applicable. The provisions of
the "Operating Procedures of the Euroclear System" and "Terms and Conditions
Governing Use of Euroclear" and the "General Terms and Conditions of Clearstream
Banking" and "Customer Handbook" of Clearstream will be applicable to transfers
of beneficial interests in the Regulation S Temporary Global Note and the
Regulation S Permanent Global Notes that are held by Participants through
Euroclear or Clearstream.

Section 2.02      Execution and Authentication.

         Two Officers must sign the Notes for or on behalf of the Company by
manual or facsimile signature.

         If an Officer whose signature is on a Note no longer holds that office
at the time a Note is authenticated, the Note will nevertheless be valid.

         A Note will not be entitled to any benefit under this Indenture or be
valid until authenticated by the manual signature of the Trustee. Such signature
will be conclusive evidence that the Note has been authenticated under this
Indenture.

         The Trustee will, upon receipt of a written order of the Company signed
by two Officers (an "Authentication Order"), authenticate Notes for original
issue up to an aggregate principal amount set forth in such Authentication
Order. The aggregate principal amount of Notes outstanding at any time may not
exceed the aggregate amount of Notes authenticated for original issue pursuant
to all the Authentication Orders issued by the Company except as provided in
Section 2.07 hereof.

         The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. 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 agent. An
authenticating agent has the same rights as an Agent to deal with Holders, the
Company, any Guarantor or any Affiliate of the Company or any Guarantor.

Section 2.03      Registrar, Paying Agent, Depositary and Custodian.

         The Company will 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"). The
Registrar will keep a register of the Notes and of their transfer and exchange.
The Company may appoint one or more co-registrars and one or more additional
paying agents. The term "Registrar" includes any co-registrar and the term
"Paying Agent" includes any additional paying agent. The Company may change any
Paying Agent or Registrar without notice to any Holder. The Company will notify
the Trustee in writing of the name and address of any Agent not a party to this
Indenture. If


                                       26

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 Domestic
Subsidiaries may act as Paying Agent or Registrar.

         The Company initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to the Global Notes.

         The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Custodian with respect to the Global Notes.

Section 2.04      Paying Agent to Hold Money in Trust.

         The Company will require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal of, or premium, if any, interest or Additional Interest, if any, on
the Notes, and will notify the Trustee of any default by the Company in making
any such payment. While any such default continues, the Trustee may require a
Paying Agent to pay all money held by it to the Trustee. The Company at any time
may require a Paying Agent to pay all money held by it to the Trustee. Upon
payment over to the Trustee, the Paying Agent (if other than the Company or any
of its Domestic Subsidiaries) will have no further liability for the money. If
the Company or any such Subsidiary acts as Paying Agent, it will segregate and
hold in 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 will serve as Paying Agent for the Notes. Each
Paying Agent shall otherwise comply with TIA Section 317(b).

Section 2.05      Holder Lists.

         The Trustee will preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA Section 312(a). If the Trustee
is not the Registrar, the Company will furnish to the Trustee at least five
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders of
Notes and the Company shall otherwise comply with TIA Section 312(a).

Section 2.06      Transfer and Exchange.

         (a) Transfer and Exchange of Global Notes. A Global Note may not be
transferred as a whole except by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. A Global Note will be exchanged by
the Company for Definitive Notes only if:

                  (1) the Company delivers to the Trustee notice from the
         Depositary that it is unwilling or unable to continue to act as
         Depositary or that it is no longer a clearing agency registered under
         the Exchange Act and, in either case, a successor Depositary is not
         appointed by the Company within 90 days after the date of such notice
         from the Depositary;

                  (2) an Event of Default has occurred with respect to the Notes
         and is continuing and the Registrar has received a request from the
         Depositary to issue Definitive Notes in lieu of all or a portion of the
         Global Notes (in which case the Company shall deliver Definitive Notes
         within 30 days of such request);


                                       27

                  (3) in the case of a Regulation S Global Note, Euroclear or
         Clearstream, as the case may be, (A) is closed for business for a
         continuous period of 14 days (other than by reason of statutory or
         other holidays), or (B) announces an intention permanently to cease
         business or does in fact do so; provided, however, that Definitive
         Notes shall only be issued in exchange for or in lieu of such
         Regulation S Global Note; or

                  (4) the Company in its sole discretion determines that the
         Global Notes (in whole but not in part) should be exchanged for
         Definitive Notes and delivers a written notice to such effect to the
         Trustee; provided that in no event shall the Regulation S Temporary
         Global Note be exchanged by the Company for Definitive Notes prior to
         (x) the expiration of the Restricted Period and (y) the receipt by the
         Registrar of any certificates required pursuant to Rule
         903(b)(3)(ii)(B) under the Securities Act.

         Upon the occurrence of any of the preceding events in (1), (2), (3) or
(4) above, Definitive Notes shall be issued in such names as the Depositary
shall instruct the Trustee in exchange for the beneficial interests in the
Global Notes so exchanged. Global Notes also may be exchanged or replaced, in
whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note
authenticated and delivered in exchange for, or in lieu of, a Global Note or any
portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof,
shall be authenticated and delivered in the form of, and shall be, a Global
Note, except as provided in the second sentence of this Section 2.06(a). A
Global Note may not be transferred or exchanged for another Note, and beneficial
interests in a Global Note shall not be exchanged in whole or in part for
Definitive Notes, other than as provided in this Section 2.06(a), however,
beneficial interests in a Global Note may be transferred and exchanged as
provided in Section 2.06(b), (c) or (f) hereof.

         (b) Transfer and Exchange of Beneficial Interests in the Global Notes.
The transfer and exchange of beneficial interests in the Global Notes will be
effected through the Depositary, in accordance with the provisions of this
Indenture and the Applicable Procedures. Beneficial interests in the Restricted
Global Notes will be subject to restrictions on transfer comparable to those set
forth herein to the extent required by the Securities Act. Transfers of
beneficial interests in the Global Notes also will require compliance with
either subparagraph (1) or (2) below, as applicable, as well as one or more of
the other following subparagraphs, as applicable:

                  (1) Transfer of Beneficial Interests in the Same Global Note.
         Beneficial interests in any Restricted Global Note may be transferred
         to Persons who take delivery thereof in the form of a beneficial
         interest in the same Restricted Global Note in accordance with the
         transfer restrictions set forth in the Private Placement Legend;
         provided, however, that prior to the expiration of the Restricted
         Period, transfers of beneficial interests in the Regulation S Temporary
         Global Note may not be made to a U.S. Person or for the account or
         benefit of a U.S. Person (other than an Initial Purchaser). Beneficial
         interests in any Unrestricted Global Note may be transferred to Persons
         who take delivery thereof in the form of a beneficial interest in an
         Unrestricted Global Note. No written orders or instructions shall be
         required to be delivered to the Registrar to effect the transfers
         described in this Section 2.06(b)(1).

                  (2) All Other Transfers and Exchanges of Beneficial Interests
         in Global Notes. In connection with all transfers and exchanges of
         beneficial interests that are not subject to Section 2.06(b)(1) above,
         the transferor of such beneficial interest must deliver to the
         Registrar either:

                           (A) both:

                                    (i) a written order from a Participant or an
                           Indirect Participant given to the Depositary in
                           accordance with the Applicable Procedures directing


                                       28

                           beneficial interest in another Global Note in an
                           amount equal to the beneficial interest to be
                           transferred or exchanged; and

                                    (ii) instructions given in accordance with
                           the Applicable Procedures containing information
                           regarding the Participant account to be credited with
                           such increase; or

                           (B) in the case of a transfer of a beneficial
                  interest in a Global Note to a Person that must take delivery
                  thereof in the form of a Definitive Note because (1) the
                  transferee is a QIB and the Rule 144A Global Note has been
                  exchanged for Definitive Notes pursuant to Section 2.06(a),
                  (2) the transferee is a Non-U.S. Person in an offshore

                  Global Note has been exchanged for Definitive Notes pursuant

                  delivery thereof in the form of an Unrestricted Global Note
                  but for the fact that such Global Note has been exchanged for
                  Definitive Notes pursuant to Section 2.06(a); or in the case
                  of an exchange of a beneficial interest in a Restricted Global
                  Note pursuant to the Exchange Offer by a Person that would
                  have taken delivery thereof in the form of an Unrestricted
                  Global Note but for the fact that such Global Note has not
                  been issued or has been exchanged for Definitive Notes
                  pursuant to Section 2.06(a), both:

                           the Depositary to cause to be issued a Definitive
                           Note in an amount equal to the beneficial interest to
                           be transferred or exchanged; and

                                    (ii) instructions given by the Depositary to
                           the Registrar containing information regarding the
                           Person in whose name such Definitive Note shall be
                           registered to effect the transfer or exchange
                           referred to in (1) above; provided that in no event
                           shall Definitive Notes be issued upon the transfer or
                           exchange of beneficial interests in the Regulation S
                           Temporary Global Note prior to (A) the expiration of
                           the Restricted Period and (B) the receipt by the
                           Registrar of any certificates required pursuant to
                           Rule 903 under the Securities Act.

                  in accordance with Section 2.06(f) hereof, the requirements of
                  this Section 2.06(b)(2) shall be deemed to have been satisfied
                  upon receipt by the Registrar of the instructions contained in
                  the Letter of Transmittal delivered by the Holder of such
                  beneficial interests in the Restricted Global Notes. Upon
                  satisfaction of all of the requirements for transfer or
                  exchange of beneficial interests in Global Notes contained in
                  this Indenture and the Notes or otherwise applicable under the

                  (3) Transfer of Beneficial Interests to Another Restricted
         Global Note. A beneficial interest in any Restricted Global Note may be
         transferred to a Person who takes delivery thereof in the form of a

                                    (i) if the Holder of such Restricted
                           Definitive Notes proposes to exchange such Notes for
                           an Unrestricted Definitive Note, a certificate from
                           such Holder in the form of Exhibit C hereto,
                           including the certifications in item (1)(c) thereof;
                           or


                                       35

                                    (ii) if the Holder of such Restricted
                           Definitive Notes proposes to transfer such Notes to a
                           Person who shall take delivery thereof in the form of
                           an Unrestricted Definitive Note, a certificate from
                           such Holder in the form of Exhibit B hereto,
                           including the certifications in item (4) thereof;

                  and, in each such case set forth in this subparagraph (D), if
                  the Registrar so requests, an Opinion of Counsel in form
                  reasonably acceptable to the Registrar and the Company to the
                  effect that such exchange or transfer is in compliance with
                  the Securities Act and that the restrictions on transfer
                  contained herein and in the Private Placement Legend are no
                  longer required in order to maintain compliance with the
                  Securities Act.

                  (3) Unrestricted Definitive Notes to Unrestricted Definitive
         Notes. A Holder of Unrestricted Definitive Notes may transfer such
         Notes to a Person who takes delivery thereof in the form of an
         Unrestricted Definitive Note. Upon receipt of a request to register
         such a transfer, the Registrar shall register the Unrestricted
         Definitive Notes pursuant to the instructions from the Holder thereof.

         (f) Exchange Offer. Upon the consummation of the Exchange Offer in
accordance with the Registration Rights Agreement, the Company will issue and,
upon receipt of an Authentication Order in accordance with Section 2.02 hereof,
the Trustee will authenticate:

                  (1) one or more Unrestricted Global Notes in an aggregate
         principal amount equal to the principal amount of the beneficial
         interests in the Restricted Global Notes accepted for exchange in the
         Exchange Offer by Persons that certify in the applicable Letters of
         Transmittal that (i) any Exchange Notes received by such Person will be
         acquired in the ordinary course of its business, (ii) such Person has
         no arrangements or understanding with any other Person to participate
         in the distribution of the Initial Notes or the Exchange Notes within
         the meaning of the Securities Act, (iii) such Person is not an
         "affiliate," as defined in Rule 405 of the Securities Act, of the
         Company or any Guarantor or if it is an affiliate, such Person will
         comply with the registration and prospectus delivery requirements of
         the Securities Act to the extent applicable, (iv) if such Person is not
         a Broker-Dealer, it is not engaged in, and does not intend to engage
         in, the distribution of the Exchange Notes, (v) if such Person is a
         Broker-Dealer, it will receive Exchange Notes for its own account in
         exchange for Initial Notes that were acquired as a result of
         market-making activities or other trading activities and that it will
         be required to acknowledge that it will deliver a prospectus in
         connection with any resale of such Exchange Notes, (vi) if such Person
         is a Broker-Dealer, it did not purchase the Initial Notes to be
         exchanged for the Exchange Notes from the Company or a Guarantor, and
         (vii) such Person is not acting on behalf of any other Person who could
         not truthfully and completely make the foregoing representations; and

                  (2) Unrestricted Definitive Notes in an aggregate principal
         amount equal to the principal amount of the Restricted Definitive Notes
         accepted for exchange in the Exchange Offer.

                  Concurrently with the issuance of such Notes under clause (1),
         the Trustee will cause the aggregate principal amount of the applicable
         Restricted Global Notes to be reduced accordingly.

         (g) Legends. The following legends will appear on the face of all
Global Notes and Definitive Notes issued under this Indenture unless

                           (B) Notwithstanding the foregoing, any Global Note or
                  Definitive Note issued pursuant to subparagraphs (b)(4),
                  (c)(3), (d)(2), (d)(3), (e)(2), (e)(3) or (f) of this Section

                  (3) Regulation S Temporary Global Note Legend. The Regulation
         S Temporary Global Note will bear a legend in substantially the
         following form:

"THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND THE
CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR CERTIFICATED NOTES, ARE AS
SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN). NEITHER THE HOLDER NOR THE
BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL NOTE SHALL BE ENTITLED
TO RECEIVE PAYMENT OF INTEREST HEREON."

         (h) Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for
Definitive Notes in accordance with the second sentence of Section 2.06(a) or a
particular Global Note has been redeemed, repurchased or canceled in whole and
not in part, each such Global Note will be returned to or retained and canceled
by the Trustee in accordance with Section 2.11 hereof. At any time prior to such
cancellation, if any beneficial interest in a Global Note is exchanged for or
transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Note or for Definitive Notes, the
principal amount of Notes represented by such Global Note will be reduced
accordingly and an endorsement will be made on such Global Note by the Trustee
or by the Depositary at the direction of the Trustee to reflect such reduction;
and if the beneficial interest is being exchanged for or transferred to a Person
who will take delivery thereof in the form of a beneficial interest in another
Global Note, such other Global Note will be


                                       38

increased accordingly and an endorsement will be made on such Global Note by the
Trustee or by the Depositary at the direction of the Trustee to reflect such
increase.

         (i) General Provisions Relating to Transfers and Exchanges.

                  (1) To permit registrations of transfers and exchanges, the
         Company will execute and the Trustee will authenticate Global Notes and
         Definitive Notes upon receipt of an Authentication Order in accordance
         with Section 2.02 or at the Registrar's request.

                  (2) No service charge will be made to a Holder of a Global
         Note or to a Holder of a Definitive Note for any registration of
         transfer or exchange, but the Company may require payment of a sum
         sufficient to cover any transfer tax or similar governmental charge
         payable in connection therewith (other than any such transfer taxes or
         similar governmental charge payable upon exchange or transfer pursuant
         to Sections 2.10, 3.06, 3.09, 4.10, 4.14 and 9.05 hereof).

                  (3) When Definitive Notes are presented to the Registrar with
         the request to register the transfer of such Definitive Notes or to
         exchange such Definitive Notes for an equal principal amount of
         Definitive Notes of other authorized denominations, the Registrar shall
         register the transfer or make the exchange as requested if its
         requirements and the requirements of this Indenture for such
         transactions are met; provided, however, that the Definitive Notes
         presented or surrendered for registration of transfer or exchange shall
         be duly endorsed or accompanied by a written instruction of transfer in
         form reasonably satisfactory to the Registrar duly executed by the
         Holder thereof or by his attorney, duly authorized in writing, on which
         instruction the Registrar can rely.

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

                  (5) Neither the Company nor the Registrar will be required:

                           (A) to register the transfer of or to exchange any
                  Notes during a period beginning at the opening of business 15
                  days before the day of any selection of Notes for redemption
                  under Section 3.02 hereof and ending at the close of business
                  on the day of selection; or

                           (B) to register the transfer of or to exchange any
                  Note selected for redemption in whole or in part, except the
                  unredeemed portion of any Note being redeemed in part.

                  (6) Prior to due presentment for the registration of a
         transfer of any Note, the Trustee, any Agent, the Company and any
         Guarantor may deem and treat the Person in whose name any Note is
         registered as the absolute owner of such Note for the purpose of
         receiving payment of principal of and interest on such Notes and for
         all other purposes, and none of the Trustee, any Agent, the Company or
         any Guarantor shall be affected by notice to the contrary.

                  (7) The Trustee will authenticate Global Notes and Definitive
         Notes in accordance with the provisions of Section 2.02 hereof.


                                       39

                  (8) All certifications, certificates and Opinions of Counsel
         required to be submitted to the Registrar pursuant to this Section 2.06
         to effect a registration of transfer or exchange may be submitted by
         facsimile.

Section 2.07      Replacement Notes.

         If any mutilated Note is surrendered to the Trustee or the Company, or
if the Holder of a Note claims that the Note has been destroyed, lost or stolen
and the Trustee and the Company receive evidence to their satisfaction of the
destruction, loss or theft of such Note, the Company will issue and the Trustee,
upon receipt of an Authentication Order, will authenticate a replacement Note if
the Trustee's requirements are met. If required by the Trustee or the Company,
an indemnity bond must be supplied by the Holder that is sufficient in the
judgment of the Trustee and the Company to protect the Company, any Guarantors,
the Trustee, any Agent and any authenticating agent from any loss that any of
them may suffer if a Note is replaced. The Company and the Trustee may charge a
Holder for their expenses in replacing a Note. If, after delivery of such
replacement Note, a protected purchaser of the original Note in lieu of which
such replacement Note was issued presents for payment or registration such
original Note, the Trustee shall be entitled to recover such replacement Note
from the party to whom it was delivered or any party taking therefrom, except a
protected purchaser, and shall be entitled to recover upon the security and
indemnity provided therefor to the extent of any loss, damage, cost or expense
incurred by the Company or the Trustee in connection therewith.

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

Section 2.08      Outstanding Notes.

         The 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, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a
Note does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note; provided, however, Notes held by the Company or a
Subsidiary of the Company shall not be deemed to be outstanding for purposes of
Section 3.07(a) hereof.

         If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a protected 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, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on and after that date such
Notes will be deemed to be no longer outstanding and will cease to accrue
interest.

Section 2.09      Treasury Notes.

         In determining whether the Holders of the required principal amount of
Notes have concurred in or consented to any direction, amendment, supplement,
waiver or consent, Notes owned by the Company, a Guarantor or any other obligor
upon the Notes or any Affiliate of the Company, of a Guarantor or of such other
obligor shall be disregarded and shall be considered as though not outstanding,
except that for the purposes of determining whether the Trustee will be
protected in relying on any such direction,


                                       40

amendment, supplement, waiver or consent, only Notes that the Trustee knows are
so owned will be so disregarded.

Section 2.10      Temporary Notes.

         Until certificates representing Notes are ready for delivery, the
Company may prepare and the Trustee, upon receipt of an Authentication Order,
will authenticate temporary Notes. Temporary Notes will be substantially in the
form of certificated Notes but may have variations that the Company considers
appropriate for temporary Notes and as may be reasonably acceptable to the
Trustee. Without unreasonable delay, the Company will prepare and the Trustee
will authenticate definitive Notes in exchange for temporary Notes.

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

Section 2.11      Cancellation.

         The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent will forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else will cancel all Notes surrendered for registration of
transfer, exchange, payment, redemption, replacement or cancellation and, unless
the Company shall direct in writing that canceled Notes be returned to it, the
Trustee shall thereafter treat and dispose of such canceled Note in accordance
with its document destruction policies. The Company may not issue new Notes to
replace Notes that it has paid or that have been delivered to the Trustee for
cancellation.

Section 2.12      Defaulted Interest.

         If the Company defaults in a payment of interest on the Notes, it will
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01 hereof. The Company will notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date
of the proposed payment. The Company will fix or cause to be fixed each such
special record date and payment date, provided that no such special record date
may be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) will mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

                                   ARTICLE 3.
                            REDEMPTION AND PREPAYMENT

Section 3.01      Notices to Trustee.

         If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at
least 30 days but not more than 60 days before a redemption date, an Officers'
Certificate setting forth:

                  (1) the clause of this Indenture pursuant to which the
         redemption shall occur;

                  (2) the redemption date;


                                       41

                  (3) the principal amount of Notes to be redeemed; and

                  (4) the redemption price.

Section 3.02      Selection of Notes to Be Redeemed.

         If less than all of the Notes are to be redeemed at any time, the
Trustee will select Notes for redemption as follows:

                  (1) if the Notes are listed on any national securities
         exchange, in compliance with the requirements of the principal national
         securities exchange on which the Notes are listed; or

                  (2) if the Notes are not listed on any national securities
         exchange, on a pro rata basis, by lot or by such method as the Trustee
         shall deem fair and appropriate.

         In the event of partial redemption or purchase by lot, the particular
Notes to be redeemed or purchased will be selected, unless otherwise provided
herein, not less than 30 nor more than 60 days prior to the redemption or
purchase date by the Trustee from the outstanding Notes not previously called
for redemption or purchase.

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

Section 3.03      Notice of Redemption.

         Subject to the provisions of Section 3.09 hereof, at least 30 days but
not more than 60 days before a redemption date, the Company will mail or cause
to be mailed, by first class mail, a notice of redemption to each Holder whose
Notes are to be redeemed at its registered address, except that redemption
notices may be mailed more than 60 days prior to a redemption date if the notice
is issued in connection with a defeasance of the Notes or a satisfaction and
discharge of this Indenture pursuant to Article 8 or 11 of this Indenture.

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

                  (1) the redemption date;

                  (2) the redemption price;

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

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


                                       42

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

                  (6) that, unless the Company defaults in making such
         redemption payment, interest on Notes called for redemption ceases to
         accrue on and after the redemption date, and the only remaining right
         of the Holder of such Notes is to receive payment of the redemption
         price upon surrender to the Paying Agent of the Notes redeemed;

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

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

         At the Company's request, the Trustee will give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company has delivered to the Trustee, at least 45 days prior to the redemption
date (unless a shorter time shall be satisfactory to the Trustee), an Officers'
Certificate requesting that the Trustee give such notice and setting forth the
information to be stated in such notice as provided in the preceding paragraph.

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. A notice of redemption may not be
conditional. Failure to give notice to a Holder or any defect in any notice
shall not affect the validity of any notice to any other Holder.

Section 3.05      Deposit of Redemption or Purchase Price.

         Prior to 10:00 a.m., New York City time, on the redemption or purchase
date, the Company will deposit with the Trustee or with the Paying Agent (or, if
the Company or any Domestic Subsidiary is acting as the Paying Agent, segregate
and hold in trust as provided in Section 2.04) money sufficient to pay the
redemption or purchase price, accrued interest and Additional Interest, if any,
on all Notes or portions thereof to be redeemed or purchased on that date. The
Trustee or the Paying Agent will promptly return to the Company any money
deposited with the Trustee or the Paying Agent by the Company in excess of the
amounts necessary to pay the redemption or purchase price, accrued interest and
Additional Interest, if any, on all Notes or portions thereof to be redeemed or
purchased.

         If the Company complies with the provisions of the preceding paragraph,
on and after the redemption or purchase date, interest will cease to accrue on
the Notes or the portions of Notes called for redemption or purchase, whether or
not such Notes are presented for payment, and the Holders of such Notes shall
have no further rights with respect to such Notes except for the right to
receive the redemption price, accrued interest and Additional Interest, if any,
upon surrender of such Notes. If a Note is redeemed or purchased on or after an
interest record date but on or prior to the related interest payment date, then
any accrued and unpaid interest shall be paid to the Person in whose name such
Note was registered at the close of business on such record date. If any Note
called for redemption or purchase is not so paid upon surrender for redemption
or purchase because of the failure of the Company to comply with the preceding
paragraph, interest shall be paid on the unpaid principal, from the redemption
or purchase 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 or Purchased in Part.

         Upon surrender to the Paying Agent of a Note that is redeemed or
purchased in part, the Company will issue and, upon receipt of an Authentication
Order, the Trustee will authenticate for the Holder at the expense of the
Company, a new Note equal in principal amount to the unredeemed or unpurchased
portion of the Note surrendered.

Section 3.07      Optional Redemption.

         (a) At any time on or prior to July 15, 2007, the Company may on any
one or more occasions redeem up to 35% of the aggregate principal amount of

more Public Equity Offerings; provided that:

         occurrence of such redemption (excluding Notes held by the Company and
         its Subsidiaries); and

                  (2) the redemption occurs within 60 days of the date of the
         closing of such Public Equity Offering.

         (b) At any time prior to July 15, 2007, the Company may also redeem all
or a part of the Notes at a redemption price equal to 100% of the principal

to the rights of Holders on the relevant record date to receive interest due on

        ----                                                    ----------

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

         (e) In the event that the Company is required to commence a Change of
Control Offer to all Holders to purchase Notes, the procedures set forth in
Section 4.14 shall apply.

Section 3.08      Mandatory Redemption.

         The Company is not required to make mandatory redemption or sinking
fund payments with respect to the Notes.


                                       44

Section 3.09      Offer to Purchase by Application of Excess Proceeds.

         In the event that, pursuant to Section 4.10 hereof, the Company is
required to commence an offer to all Holders to purchase Notes (an "Asset Sale
Offer"), it will follow the procedures specified below.

         The Asset Sale Offer shall be made to all Holders and all holders of
other Pari Passu Indebtedness containing provisions similar to those set forth
in this Indenture with respect to offers to purchase or redeem with the proceeds
of sales of assets. The Asset Sale Offer will remain open for a period of at
least 20 Business Days following its commencement and not more than 30 Business
Days, except to the extent that a longer period is required by applicable law
(the "Offer Period"). No later than five Business Days after the termination of
the Offer Period (the "Purchase Date"), the Company will apply all Excess
Proceeds (the "Offer Amount") to the purchase of Notes and such other Pari Passu
Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer
Amount has been tendered, all Notes and other Indebtedness tendered in response
to the Asset Sale Offer. Payment for any Notes so purchased will be made in the
same manner as redemption payments are made.

         If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest and
Additional Interest, if any, will 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 will be payable to Holders who tender Notes pursuant to the Asset Sale
Offer.

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

                  (1) that the Asset Sale Offer is being made pursuant to this
         Section 3.09 and Section 4.10 hereof and the length of time the Asset
         Sale Offer will remain open;

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

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

                  (4) that, unless the Company defaults in making such payment,
         any Note accepted for payment pursuant to the Asset Sale Offer will
         cease to accrue interest after the Purchase Date, and the only
         remaining right of the Holder of such Note is to receive payment of the
         purchase price upon surrender of the Note so purchased to the Company
         or the Paying Agent;

                  (5) that Holders electing to have a Note purchased pursuant to
         an Asset Sale Offer may elect to have Notes purchased in integral
         multiples of $1,000 only;

                  (6) that Holders electing to have a Note purchased pursuant to
         any Asset Sale Offer will be required to surrender the Note, with the
         form entitled "Option of Holder to Elect Purchase" on the reverse of
         the Note completed, or transfer by book-entry transfer, to the Company
         or a Paying Agent at the address specified in the notice prior to the
         close of business on the third Business Day preceding the Purchase
         Date;

                  (7) that Holders will be entitled to withdraw their election
         if the Company or the Paying Agent, as the case may be, receives, not
         later than the expiration of the Offer Period, a facsimile transmission
         or letter setting forth the name of the Holder, the principal amount of
         the


                                       45

         Note the Holder delivered for purchase and a statement that such Holder
         is withdrawing his election to have such Note purchased;

                  (8) that, if the aggregate principal amount of Notes and other
         Pari Passu Indebtedness surrendered by Holders exceeds the Offer
         Amount, the Company will select the Notes and other Pari Passu
         Indebtedness to be purchased on a pro rata basis based on the principal
         amount of Notes and such other Pari Passu Indebtedness tendered (with
         such adjustments as may be deemed appropriate by the Company so that
         only Notes in denominations of $1,000, or integral multiples thereof,
         will be purchased); and

                  (9) that Holders whose Notes are being purchased only in part
         will be issued new Notes equal in principal amount to the unpurchased
         portion of the Notes surrendered (or transferred by book-entry
         transfer), which unpurchased portion must be equal to $1,000 in
         principal amount or an integral multiple thereof.

         On or before the Purchase Date, the Company will, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Notes or portions thereof and other Pari Passu Indebtedness tendered
pursuant to the Asset Sale Offer, or if less than the Offer Amount has been
tendered, all Notes and other Pari Passu Indebtedness tendered, and will deliver
to the Trustee an Officers' Certificate stating that such Notes or portions
thereof and such other Pari Passu Indebtedness were accepted for payment by the
Company in accordance with the terms of this Section 3.09. The Company or the
Paying Agent, as the case may be, will promptly (but in any case not later than
five Business Days after the Purchase Date) mail or deliver to each tendering
Holder an amount equal to the purchase price of the Notes tendered by such
Holder and accepted by the Company for purchase, and the Company will promptly
issue a new Note, and the Trustee, upon written request from the Company will
authenticate and mail or deliver such new Note to such Holder, in a principal
amount equal to any unpurchased portion of the Note surrendered; provided that
each new Note will be in a principal amount of $1,000 or an integral multiple
thereof. Any Note not so accepted shall be promptly mailed or delivered by the
Company to the Holder thereof.

         The Company will comply with the provisions of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such provisions are applicable in connection with each purchase of Notes
pursuant to an Asset Sale Offer. To the extent that the provisions of any
securities laws or regulations conflict with this Section 3.09 or Section 4.10
hereof, the Company will comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations under this
Section 3.09 or Section 4.10 hereof by virtue of such conflict.

         Other than as specifically provided in this Section 3.09 or 4.10, any
purchase pursuant to this Section 3.09 shall be made pursuant to the provisions
of Sections 3.05 and 3.06 hereof.

Section 3.10      Purchase of Securities.

         The Company, any Guarantor and any Affiliate of the Company or any
Guarantor may, subject to applicable law, at any time purchase or otherwise
acquire Notes in the open market or by private agreement. Any such acquisition
shall not operate as or be deemed for any purpose to be a redemption of the
Indebtedness represented by such Notes. Any Notes purchased or acquired by the
Company or a Guarantor shall be delivered to the Trustee and, upon such
delivery, the Indebtedness represented thereby shall be deemed to be satisfied.
Section 2.11 shall apply to all Notes so delivered.

                                   ARTICLE 4.
                                   COVENANTS

Section 4.01      Payment of Notes.

         The Company will pay or cause to be paid the principal of, and premium,
if any, interest and Additional Interest, if any, on the Notes on the dates and
in the manner provided in the Notes and this Indenture. Principal of, and
premium, if any, interest and Additional Interest, if any, will be considered
paid on the date due if the Paying Agent, if other than the Company or a
Domestic Subsidiary thereof, holds as of 11:00 a.m. Eastern Time on the due date
money deposited by the Company in immediately available funds and designated for
and sufficient to pay all principal of, and premium, if any, interest and
Additional Interest, if any, then due. The Company will pay all Additional
Interest, if any, in the same manner on the dates and in the amounts set forth
in the Registration Rights Agreement.

         The Company will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
at the rate equal to 1% per annum in excess of the then applicable interest rate
on the Notes to the extent lawful; it will pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest and Additional Interest, if any (without regard to any applicable grace
period) at the same rate to the extent lawful.

         Notwithstanding anything to the contrary contained in this Indenture,
the Company may, to the extent it is required to do so by law and without the
payment of any additional or gross up amounts with respect thereto, deduct or
withhold income or other similar taxes imposed by the laws of the United States,
any state of the United States or the District of Columbia from any payments of
principal, or premium, if any, interest or Additional Interest, if any,
hereunder.

Section 4.02      Maintenance of Office or Agency.

         The Company will maintain in the Borough of Manhattan, the City of New
York, an office or agency (which may be an office of the Trustee or an affiliate
of the Trustee, Registrar or the Paying Agent) where Notes may be surrendered
for registration of transfer or for exchange and where notices and demands to or
upon the Company or any Guarantor in respect of the Notes, the Note Guarantees
and this Indenture may be served. The Company will give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company fails to maintain any such required office or
agency or fails to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee.

         The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission will in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes. The Company will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

         The Company hereby designates the Corporate Trust Office of the Trustee
as one such office or agency of the Company in accordance with Section 2.03
hereof.


                                       47

Section 4.03      Reports.

           (a) Prior to consummation of the Exchange Offer, whether or not
required by the rules and regulations of the SEC, so long as any Notes are
outstanding, the Company will furnish to the Trustee, within 15 days after it
would have been required to file the same with the SEC if the Company had been
subject to the periodic reporting requirements of Section 13 or 15(d) of the
Exchange Act and excluding any time periods applicable to "accelerated filers"
under the Exchange Act, quarterly and annual financial statements, including any
notes thereto (and with respect to annual financial statements only, an
auditors' report thereon by a firm of established national reputation), and a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," both comparable to that which the Company would have been required
to include in a quarterly report on Form 10-Q or an annual report on Form 10-K
if the Company had been subject to those periodic reporting requirements.

         (b) Following the consummation of the Exchange Offer, whether or not
required by the rules and regulations of the SEC, so long as any Notes are
outstanding, the Company will file with the SEC (unless the SEC will not accept
such a filing):

                  (1) all quarterly and annual reports on Forms 10-Q and 10-K
         required to be filed with the SEC pursuant to Section 13 or 15(d) of
         the Exchange Act; and

                  (2) all current reports on Form 8-K required to be filed with
         the SEC pursuant to Section 13 or 15(d) of the Exchange Act;

in each case, for public availability within the time periods specified in the
rules and regulations applicable to such reports. The Company will not take any
action for the purpose of causing the SEC not to accept any such filings. If the
SEC will not accept the Company's filings for any reason, the Company will post
the reports referred to in clauses (1) and (2) of this Section 4.03(b) on its
website within the time periods that would apply if the Company were required to
file those reports with the SEC. If this Indenture is qualified under the TIA,
but not otherwise, the Company and the Guarantors shall also comply with the
provisions of TIA Section 314(a).

         (c) As long as the Company is not subject to the reporting requirements
of Section 13 or 15(d) of the Exchange Act, the Company will furnish to the
Holders and to prospective purchasers of the Notes designated by the Holders,
promptly upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.

         (d) The Company intends to file the reports referred to in clauses (1)
and (2) of Section 4.03(b) hereof with the SEC in electronic form pursuant to
Regulation S-T of the SEC using the SEC's Electronic Data Gathering, Analysis
and Retrieval ("EDGAR") system. The Company shall notify the Trustee in the
manner prescribed herein of each such filing. The Trustee is hereby authorized
and directed to access the EDGAR system for purposes of retrieving the reports
so filed. Compliance with the foregoing shall constitute delivery by the Company
of such reports to the Trustee in compliance with the provisions of TIA Section
314(a). The Trustee shall have no duty to search for or obtain any electronic or
other filings that the Company makes with the SEC, regardless of whether such
filings are periodic, supplemental or otherwise. Delivery of the reports,
information and documents to the Trustee pursuant to this Section 4.03 shall be
solely for the purposes of compliance with this Section 4.03 and with TIA
Section 314(a). The Trustee's receipt of such reports, information and documents
shall not constitute notice to it of the content thereof or of any matter
determinable from the content thereof, including the Company's compliance with
any of its covenants hereunder, as to which the Trustee is entitled to rely upon
Officers' Certificates.


                                       48

Section 4.04      Compliance Certificate.

         (a) The Company and each Guarantor (to the extent that such Guarantor
is so required under the TIA) shall deliver to the Trustee, within 120 days
after the end of each fiscal year, a statement signed by an Officer of the
Company or such Guarantor, as the case may be, which need not constitute an
Officers' Certificate, complying with TIA Section 314(a)(4) and stating that a
review of the activities of the Company or such Guarantor, as the case may be,
during the preceding fiscal year has been made under the supervision of the
signing Officer with a view to determining whether the Company or such
Guarantor, as the case may be, has kept, observed, performed and fulfilled its
obligations under this Indenture, and further stating, as to each such Officer
signing such certificate, that to the best of his or her knowledge the Company
or such Guarantor, as the case may be, has kept, observed, performed and
fulfilled each and every covenant contained in this Indenture and is not in
default in the performance or observance of any of the terms, provisions and
conditions of this Indenture (or, if a Default or Event of Default has occurred,
describing all such Defaults or Events of Default of which he or she may have
knowledge and what action the Company or such Guarantor, as the case may be, is
taking or proposes to take with respect thereto) and that to the best of his or
her knowledge no event has occurred and remains in existence by reason of which
payments on account of the principal of or interest, if any, on the Notes is
prohibited or if such event has occurred, a description of the event and what
action the Company or such Guarantor, as the case may be, is taking or proposes
to take with respect thereto.

         (b) So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(a) above shall be accompanied by a
written statement of the Company's independent public accountants (who shall be
a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 hereof insofar as they relate to
accounting matters or, if any such violation has occurred, specifying the nature
and period of existence thereof, it being understood that such accountants shall
not be liable directly or indirectly to any Person for any failure to obtain
knowledge of any such violation.

         (c) So long as any of the Notes are outstanding, the Company will
deliver to the Trustee, forthwith upon any Officer becoming aware of any Default
or Event of Default, an Officers' Certificate specifying such Default or Event
of Default and what action the Company is taking or proposes to take with
respect thereto.

Section 4.05      Taxes.

         The Company will pay, and will cause each of its Restricted
Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and
governmental levies imposed upon the Company or any of its Restricted
Subsidiaries or any of their respective properties, except such as are contested
in good faith and by appropriate proceedings or where the failure to effect such
payment is not adverse in any material respect to the Holders of the Notes.

Section 4.06      Stay, Extension and Usury Laws.

         The Company and each of the Guarantors covenants (to the extent that it
may lawfully do so) that it will not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law wherever enacted, now or at any time hereafter in force, that may
affect the covenants or the performance of this Indenture; and the Company and
each of 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


                                       49

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 has been enacted.

Section 4.07      Restricted Payments.

         (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly:

                  (1) declare or pay any dividend or make any other distribution
         on account of the Company's or any of its Restricted Subsidiaries'
         Equity Interests (including, without limitation, any payment in
         connection with any merger or consolidation involving the Company or
         any of its Restricted Subsidiaries) or to the direct or indirect
         holders of the Company's or any of its Restricted Subsidiaries' Equity
         Interests in their capacity as such (other than dividends or
         distributions payable in Equity Interests (other than Disqualified
         Stock) of the Company or to the Company or a Restricted Subsidiary of
         the Company);

                  (2) purchase, redeem or otherwise acquire or retire for value
         (including without limitation, in connection with any merger or
         consolidation involving the Company) any Equity Interests of the
         Company or any direct or indirect parent of the Company;

                  (3) make any payment on or with respect to, or purchase,
         redeem, defease or otherwise acquire or retire for value, any
         Indebtedness of the Company or any Guarantor that is contractually
         subordinated to the Notes or any Note Guarantee (excluding any
         intercompany Indebtedness between or among the Company and any of its
         Restricted Subsidiaries), except a payment of interest or principal at
         or after the Stated Maturity of such interest or principal; or

                  (4) make any Restricted Investment

                  (all such payments and other actions set forth in clauses (1)
                  through (4) above being collectively referred to as
                  "Restricted Payments"), unless, at the time of and after
                  giving effect to such Restricted Payment:

                           (i) no Default or Event of Default has occurred and
                  is continuing or would occur as a consequence of such
                  Restricted Payment; and

                           (ii) the Company would, at the time of such
                  Restricted Payment and after giving pro forma effect thereto
                  as if such Restricted Payment had been made at the beginning
                  of the applicable four-quarter period, have been permitted to
                  incur at least $1.00 of additional Indebtedness pursuant to
                  the Fixed Charge Coverage Ratio test set forth in Section
                  4.09(a) hereof; and

                           (iii) such Restricted Payment, together with the
                  aggregate amount of all other Restricted Payments made by the
                  Company and its Restricted Subsidiaries since the date hereof
                  (excluding Restricted Payments permitted by clauses (2), (3),
                  (4), (6), (7), (8), (9), (10) and (11) of Section 4.07(b)
                  below), is less than the sum, without duplication, of:

                                    (A) 50% of the Consolidated Net Income of
                           the Company for the period (taken as one accounting
                           period) from the beginning of the first fiscal
                           quarter commencing after the date hereof to the end
                           of the Company's most recently ended fiscal quarter
                           for which internal financial statements are available
                           at the time of such Restricted Payment (or, if such
                           Consolidated Net Income for


                                       50

                           such period is a deficit, less 100% of such deficit);
                           provided, however, that if at any time after the date
                           hereof the Notes are rated Investment Grade, the
                           percentage will be 100% of Consolidated Net Income
                           for such period; provided, further, however, that if
                           such Restricted Payment is to be made in reliance
                           upon an additional amount permitted pursuant to the
                           immediately preceding proviso, the Notes must be
                           rated Investment Grade at the time such Restricted
                           Payment is declared or, if not declared, made, plus

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

                                    (C) to the extent that any Restricted
                           Investment that was made after the date hereof is
                           sold for cash or otherwise liquidated, repaid for
                           cash or otherwise reduced, the lesser of (i) the cash
                           return of capital with respect to such Restricted
                           Investment (less the cost of disposition, if any) and
                           (ii) the initial amount of such Restricted
                           Investment, plus

                                    (D) to the extent that any Unrestricted
                           Subsidiary of the Company is redesignated as a
                           Restricted Subsidiary after the date hereof, the Fair
                           Market Value of the Company's Investment in such
                           Subsidiary as of the date of such redesignation, plus

                                    (E) 50% of any dividends received by the
                           Company or a Restricted Subsidiary of the Company
                           that is a Guarantor after the date hereof from an
                           Unrestricted Subsidiary or a Joint Venture, to the
                           extent that such dividends were not otherwise
                           included in Consolidated Net Income of the Company
                           for such period; provided, however, that if at any
                           time after the date hereof the Notes are rated
                           Investment Grade, the percentage will be 100% of any
                           such dividends; provided, further, however, that if
                           such Restricted Payment is to be made in reliance
                           upon an additional amount permitted pursuant to the
                           immediately preceding proviso, the Notes must be
                           rated Investment Grade at the time such Restricted
                           Payment is declared or, if not declared, made.

         (b) So long as no Default has occurred and is continuing or would be
caused thereby, the provisions of Section 4.07(a) will not prohibit:

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

                  (2) the making of any Restricted Payment in exchange for, or
         out of the net cash proceeds of the substantially concurrent issuance
         or sale (other than to a Subsidiary of the Company) of, Equity
         Interests of the Company (other than Disqualified Stock) or from the
         substantially concurrent contribution of common equity capital to the
         Company; provided that the


                                       51

         amount of any such net cash proceeds that are utilized for any such
         redemption, repurchase, retirement, defeasance or other acquisition
         will be excluded from Section 4.07(a)(iii)(B) hereof;

                  (3) the defeasance, redemption, repurchase or other

         Permitted Refinancing Indebtedness;

                  (4) the payment of any dividend (or, in the case of any
         partnership or limited liability company, any similar distribution) by
         a Restricted Subsidiary to the Company or another Restricted
         Subsidiary, or the purchase, redemption or other acquisition or
         retirement of any Equity Interests in a Restricted Subsidiary held by
         the Company or another Restricted Subsidiary;

                  (5) the repurchase, redemption or other acquisition or
         retirement for value of any Equity Interests of the Company or any
         Restricted Subsidiary of the Company held by any current or former
         officer, director or employee of the Company or any of its Restricted
         Subsidiaries pursuant to any equity subscription agreement, stock
         option agreement, shareholders' agreement or similar plan or agreement;
         provided that the aggregate price paid for all such repurchased,
         redeemed, acquired or retired Equity Interests may not exceed $1.0
         million in any twelve-month period;

                  (6) the repurchase of Equity Interests deemed to occur upon
         the exercise of stock options to the extent such Equity Interests
         represent a portion of the exercise price of those stock options;

                  (7) the declaration and payment of dividends to holders of any
         class or series of Disqualified Stock of the Company or any Restricted

         principal amount thereof in the event of (x) a change of control
         pursuant to a provision no more favorable to the holders thereof than
         the provision set forth in Section 4.14 hereof or (y) an Asset Sale
         (pursuant to a provision no more favorable to the holders thereof than
         the provision set forth in Section 4.10 hereof); provided that in each
         case, prior to such repurchase the Company has made a Change of Control
         Offer or Asset Sale Offer, as applicable, and repurchased all Notes
         that were validly tendered for payment in connection with such Change
         of Control Offer or Asset Sale Offer;

Fair Market Value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The Fair Market Value of any assets or securities that are required to be valued
by this Section 4.07 will be


                                       52

shall be delivered to the Trustee. The Board of Directors' determination must be
based upon an opinion or appraisal issued by an accounting, appraisal or
investment banking firm of national standing if the Fair Market Value exceeds
$15.0 million.

Section 4.08      Dividend and Other Payment Restrictions Affecting
Subsidiaries.

         (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to:

                  (1) pay dividends or make any other distributions on its
         Capital Stock to the Company or any of its Restricted Subsidiaries or
         with respect to any other interest or participation in, or measured by,
         its profits, or pay any indebtedness owed to the Company or any of its
         Restricted Subsidiaries;

                  (2) make loans or advances to the Company or any of its
         Restricted Subsidiaries; or

                  (3) transfer any of its properties or assets to the Company or
         any of its Restricted Subsidiaries.

         (b) The restrictions in Section 4.08(a) will not apply to encumbrances
or restrictions existing under or by reason of:

                  (1) agreements governing Existing Indebtedness and Credit
         Facilities as in effect on the date hereof and any amendments,
         modifications, restatements, renewals, increases, supplements,
         refundings, replacements or refinancings of those agreements; provided
         that such amendments, modifications, restatements, renewals, increases,
         supplements, refundings, replacements or refinancings are not
         materially more restrictive, taken as a whole, with respect to such
         dividend and other payment restrictions than those contained in those
         agreements, as in effect on the date hereof;

                  (2) this Indenture, the Notes and the Note Guarantees;

                  (3) applicable law, rule, regulation or order;

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

                  (5) customary non-assignment provisions in contracts and
         leases entered into in the ordinary course of business;

                  (6) construction loans and purchase money obligations for
         property acquired in the ordinary course of business and Capital Lease
         Obligations that impose restrictions on the property constructed,
         purchased or leased of the nature described in Section 4.08(a)(3);


                                       53

                  (7) any agreement for the sale or other disposition of a
         Restricted Subsidiary that restricts distributions by that Restricted
         Subsidiary pending the sale or other disposition;

                  (8) Permitted Refinancing Indebtedness, provided that the
         restrictions contained in the agreements governing such Permitted
         Refinancing Indebtedness are not materially more restrictive, taken as
         a whole, than those contained in the agreements governing the
         Indebtedness being refinanced;

                  (9) Liens securing Indebtedness otherwise permitted to be
         incurred under the provisions of Section 4.12 hereof that limit the
         right of the debtor to dispose of the assets subject to such Liens;

                  (10) any restriction under an agreement governing Indebtedness
         of a Foreign Subsidiary permitted under Section 4.09 hereof;

                  (11) provisions limiting or prohibiting the disposition or
         distribution of assets or property in joint venture agreements, asset
         sale agreements, sale-leaseback agreements, stock sale agreements and
         other similar agreements entered into with the approval of the
         Company's Board of Directors, which limitation or prohibition is
         applicable only to the assets that are the subject of such agreements;
         and

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

         For purposes of determining compliance with this Section 4.08, in the
event that a restriction meets the criteria of more than one of the categories
of permitted restrictions described in clauses (1) through (12) of this Section
4.08(b), the Company will be permitted to classify such restriction on the date
of its incurrence, or later reclassify all or a portion of such item of
Indebtedness, in any manner that complies with this Section 4.08.

Section 4.09      Incurrence of Indebtedness and Issuance of Preferred Stock.

         (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt), and the Company will not issue any Disqualified Stock and will not permit
any of its Restricted Subsidiaries to issue any shares of preferred stock;
provided, however, that the Company may incur Indebtedness (including Acquired
Debt) or issue Disqualified Stock and the Guarantors may incur Indebtedness or
issue preferred stock, if the Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which internal financial statements
are available immediately preceding the date on which such additional
Indebtedness is incurred or such Disqualified Stock or preferred stock is issued
would have been at least 2.0 to 1, determined on a pro forma basis (including a
pro forma application of the net proceeds therefrom and, in the case of Acquired
Debt, giving pro forma effect to the applicable transaction related thereto), as
if the additional Indebtedness had been incurred (and such transaction had
occurred) or the preferred stock or Disqualified Stock had been issued, as the
case may be, at the beginning of such four-quarter period.

         (b) The provisions of Section 4.09(a) will not prohibit the incurrence
of any of the following items of Indebtedness (collectively, "Permitted Debt"):


                                       54

                  (1) the incurrence by the Company or any Guarantor of
         additional Indebtedness and letters of credit under Credit Facilities
         in an aggregate principal amount at any one time outstanding under this
         clause (1) (with letters of credit being deemed to have a principal
         amount equal to the maximum potential liability of the Company and its
         Subsidiaries thereunder) not to exceed the greater of (x) $320.0
         million less the aggregate amount of all Net Proceeds of Asset Sales
         applied by the Company or any of its Restricted Subsidiaries since the
         date hereof to repay any term Indebtedness under a Credit Facility or
         to repay any revolving credit Indebtedness under a Credit Facility and
         effect a corresponding commitment reduction thereunder pursuant to
         Section 4.10 hereof or (y) the amount of the Borrowing Base as of the
         date of such incurrence;

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

                  (3) the incurrence by the Company and the Guarantors of
         Indebtedness represented by the Notes and the related Note Guarantees
         to be issued on the date hereof and the Exchange Notes and the related
         Note Guarantees to be issued in accordance with the Registration Rights
         Agreement;

                  (4) the incurrence by the Company or any of its Restricted
         Subsidiaries of Indebtedness represented by Capital Lease Obligations,
         mortgage financings or purchase money obligations, in each case,
         incurred for the purpose of financing all or any part of the purchase
         price or cost of design, construction, installation or improvement of
         property, plant or equipment used or usable in a Permitted Business, in
         an aggregate principal amount, including all Permitted Refinancing
         Indebtedness incurred to refund, refinance or replace any Indebtedness
         incurred pursuant to this clause (4), not to exceed $10.0 million at
         any time outstanding;

                  (5) the incurrence by the Company or any of its Restricted
         Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or
         the net proceeds of which are used to extend, refund, refinance, renew,
         defease or replace Indebtedness (other than intercompany Indebtedness)
         that was permitted by this Indenture to be incurred under Section
         4.09(a) or clauses (2), (3), (4), (5) or (16) of this Section 4.09(b);

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

                           (A) if the Company or any Guarantor is the obligor on
                  such Indebtedness and the payee is not the Company or a
                  Guarantor, such Indebtedness must be expressly subordinated to
                  the prior payment in full in cash of all Obligations then due
                  with respect to the Notes, in the case of the Company, or the
                  Note Guarantee, in the case of a Guarantor; and

                           (B) (1) any subsequent issuance or transfer of Equity
                  Interests that results in any such Indebtedness being held by
                  a Person other than the Company or a Restricted Subsidiary of
                  the Company and (2) any sale or other transfer of any such
                  Indebtedness to a Person that is not either the Company or a
                  Restricted Subsidiary of the Company will be deemed, in each
                  case, to constitute an incurrence of such Indebtedness by the
                  Company or such Restricted Subsidiary, as the case may be,
                  that was not permitted by this clause (6);


                                       55

                  (7) the issuance by any of the Company's Restricted
         Subsidiaries to the Company or to any of its Restricted Subsidiaries of
         shares of preferred stock; provided, however, that:

                           (A) any subsequent issuance or transfer of Equity
                  Interests that results in any such preferred stock being held
                  by a Person other than the Company or a Restricted Subsidiary
                  of the Company; and

                           (B) any sale or other transfer of any such preferred
                  stock to a Person that is not either the Company or a
                  Restricted Subsidiary of the Company;

    will be deemed, in each case, to constitute an issuance of such preferred
    stock by such Restricted Subsidiary that was not permitted by this clause
    (7);

                  (8) the incurrence by the Company or any of its Restricted
         Subsidiaries of Hedging Obligations in the ordinary course of business
         and not for speculative purposes;

                  (9) the guarantee by the Company or any of the Guarantors of
         Indebtedness of the Company or a Restricted Subsidiary of the Company
         that was permitted to be incurred by another provision of this Section
         4.09; provided that if the Indebtedness being guaranteed is
         subordinated to or pari passu with the Notes, then the guarantee shall
         be subordinated to the same extent as the Indebtedness guaranteed;

                  (10) the incurrence by the Company or any of its Restricted
         Subsidiaries of Indebtedness in respect of workers' compensation
         claims; self-insurance obligations; bankers' acceptances; performance,
         appeal, completion, guarantee and surety bonds; or similar requirements
         in the ordinary course of business;

                  (11) the incurrence by the Company or any of its Restricted
         Subsidiaries of Indebtedness arising from the honoring by a bank or
         other financial institution of a check, draft or similar instrument
         inadvertently drawn against insufficient funds, so long as such
         Indebtedness is covered within five business days;

                  (12) the incurrence by Foreign Subsidiaries of Indebtedness in
         an aggregate principal amount at any time outstanding pursuant to this
         clause (12), including all Permitted Refinancing Indebtedness incurred
         to refund, refinance, defease, renew, extend or replace Indebtedness
         incurred pursuant to this clause (12), not to exceed $10.0 million;

                  (13) the incurrence by the Company or a Restricted Subsidiary
         of Indebtedness arising from agreements of the Company or such
         Restricted Subsidiary providing for indemnification, adjustment of
         purchase price or similar obligations, in each case, incurred in
         connection with the disposition of any business, assets or subsidiary,
         other than guarantees of Indebtedness incurred by any Person acquiring
         all or any portion of such business, assets or subsidiary for the
         purpose of financing such acquisition; provided that the maximum
         aggregate liability in respect of all such Indebtedness shall at no
         time exceed the gross proceeds actually received by the Company or such
         Restricted Subsidiary in connection with such disposition;

                  (14) the incurrence by the Company or a Restricted Subsidiary
         of Indebtedness consisting of take-or-pay obligations contained in
         supply agreements entered into in the ordinary course of business;


                                       56

                  (15) the incurrence by the Company of Indebtedness to any of
         its Subsidiaries incurred in connection with the purchase of accounts
         receivable and related assets by the Company from any such Subsidiary
         which assets are subsequently conveyed by the Company in connection
         with a Receivable Facility; and

                  (16) the incurrence by the Company or any of the Guarantors of
         additional Indebtedness in an aggregate principal amount (or accreted
         value, as applicable) at any time outstanding, including all Permitted
         Refinancing Indebtedness incurred to extend, refund, refinance, renew,
         defease or replace any Indebtedness incurred pursuant to this clause
         (16), and the issuance by the Company of any Disqualified Stock and by
         any Restricted Subsidiary of any additional preferred stock, not to
         exceed $50.0 million.

         The Company will not incur, and will not permit any Guarantor to incur,
any Indebtedness (including Permitted Debt) that is contractually subordinated
in right of payment to any other Pari Passu Indebtedness of the Company or such
Guarantor unless such Indebtedness is also contractually subordinated in right
of payment to the Notes and the related Note Guarantee on substantially
identical terms; provided, however, that no Indebtedness shall be deemed to be
contractually subordinated in right of payment to any other Indebtedness of the
Company solely by virtue of being unsecured or by virtue of being secured on a
first or junior Lien basis.

         For purposes of determining compliance with this Section 4.09, in the
event that an item of proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in clauses (1) through (16) of
Section 4.09(b) or is entitled to be incurred pursuant to Section 4.09(a), the
Company will be permitted to classify such item of Indebtedness on the date of
its incurrence, or later reclassify all or a portion of such item of
Indebtedness, in any manner that complies with this Section 4.09. Indebtedness
under Credit Facilities outstanding on the date on which Notes are first issued
and authenticated under this Indenture will be deemed to have been incurred on
such date in reliance on the exception provided by clause (1) of Section
4.09(b). The accrual of interest, the accretion or amortization of original
issue discount, the payment of interest on any Indebtedness in the form of
additional Indebtedness with the same terms, and the payment of dividends on
Disqualified Stock in the form of additional shares of the same class of
Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an
issuance of Disqualified Stock for purposes of this Section 4.09; provided, in
each such case, that the amount thereof is included in the Fixed Charges of the
Company as accrued. Notwithstanding any other provision of this Section 4.09,
the maximum amount of Indebtedness that the Company or any Restricted Subsidiary
may incur pursuant to this Section 4.09 shall not be deemed to be exceeded
solely as a result of fluctuations in exchange rates or currency values.

Section 4.10      Asset Sales.

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

                  (1) the Company or the Restricted Subsidiary, as the case may
         be, receives consideration at the time of such Asset Sale at least
         equal to the Fair Market Value (as determined by the Company's Board of
         Directors and evidenced by a Board Resolution set forth in an Officers'
         Certificate delivered to the Trustee) of the assets or Equity Interests
         issued or sold or otherwise disposed of; and

                  (2) at least 75% of the consideration received in the Asset
         Sale by the Company or such Restricted Subsidiary is in the form of
         cash or Cash Equivalents or a controlling interest in a


                                       57

         business engaged in a Permitted Business. For purposes of this Section
         4.10(a)(2), each of the following shall also be deemed to be cash:

                           (A) any liabilities, as shown on its most recent
                  balance sheet, of the Company or such 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 of any such assets pursuant
                  to a customary novation agreement that releases the Company or
                  such Restricted Subsidiary from further liability;

                           (B) any securities, notes or other obligations
                  received by the Company or any such Restricted Subsidiary from
                  such transferee that are promptly, subject to ordinary
                  settlement periods, converted or monetized by the Company or
                  such Restricted Subsidiary into cash, to the extent of the
                  cash received in that conversion or monetization; and

                           (C) any stock or assets of the kind referred to in
                  clauses (2) or (4) of Section 4.10(b).

         (b) Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Company (or the applicable Restricted Subsidiary, as the case may be)
may apply such Net Proceeds at its option:

                  (1) to repay Indebtedness and other Obligations under a Credit
         Facility and, if the Indebtedness repaid is revolving credit
         Indebtedness, to correspondingly reduce commitments with respect
         thereto;

                  (2) to acquire all or substantially all of the assets of, or
         any Capital Stock of, any Person or division thereof conducting a
         Permitted Business, if, in the case of any such acquisition of Capital
         Stock and after giving effect thereto, such Person will be a Restricted
         Subsidiary of the Company (or enter into a binding commitment for any
         such acquisition); provided that such binding commitment shall be
         treated as a permitted application of Net Proceeds from the date of
         such commitment until and only until the earlier of (x) the date on
         which such acquisition is consummated and (y) the 180th day following
         the expiration of the aforementioned 360-day period. If the acquisition
         or expenditure contemplated by such binding commitment is not
         consummated on or before such 180th day and the Company or such
         Restricted Subsidiary shall not have applied such Net Proceeds pursuant
         to clause (1), (3) or (4) of this Section 4.10(b) on or before such
         180th day, such commitment shall be deemed not to have been a permitted
         application of Net Proceeds;

                  (3) to make a capital expenditure; or

                  (4) to acquire other assets that are not classified as current
         assets under GAAP and that are used or useful in a Permitted Business.

         (c) Pending the final application of any such Net Proceeds, the Company
may temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner that is not prohibited by this Indenture. Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the
preceding paragraph will constitute "Excess Proceeds." When the aggregate amount
of Excess Proceeds exceeds $15.0 million, within ten days thereof, the Company
shall make an Asset Sale Offer to all Holders and all holders of other Pari
Passu Indebtedness containing provisions similar to those set forth in this
Indenture with respect to offers to purchase or redeem with the proceeds of
asset sales to purchase the maximum principal amount of Notes and such other
Pari Passu Indebtedness that


                                       58

may be purchased out of the Excess Proceeds. The offer price in any Asset Sale
Offer will be equal to 100% of principal amount plus accrued and unpaid interest
and Additional Interest, if any, to the date of purchase, and will be payable in
cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer,
the Company may use such Excess Proceeds for any purpose not otherwise
prohibited by this Indenture. If the aggregate principal amount of Notes and
other Pari Passu Indebtedness tendered into such Asset Sale Offer exceeds the
amount of Excess Proceeds, the Trustee shall select the Notes and such other
Pari Passu Indebtedness to be purchased on a pro rata basis based on the
principal amount of Notes and such other Pari Passu Indebtedness tendered. Upon
completion of each Asset Sale Offer, the amount of Excess Proceeds shall be
reset at zero.

Section 4.11      Transactions with Affiliates.

         (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate of the Company (each 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 might reasonably have been obtained in a comparable
         transaction by the Company or such Restricted Subsidiary with an
         unrelated Person; and

                  (2) the Company delivers to the Trustee:

                           (A) with respect to any Affiliate Transaction or
                  series of related Affiliate Transactions involving aggregate
                  consideration in excess of $5.0 million, a Board Resolution
                  set forth in an Officers' Certificate certifying that such
                  Affiliate Transaction complies with this Section 4.11 and that
                  such Affiliate Transaction has been approved by a majority of
                  the members of the Board of Directors; and

                           (B) with respect to any Affiliate Transaction or
                  series of related Affiliate Transactions involving aggregate
                  consideration in excess of $15.0 million, an opinion as to the
                  fairness to the Company or such Restricted Subsidiary of such
                  Affiliate Transaction from a financial point of view issued by
                  an accounting, appraisal or investment banking firm of
                  national standing.

         (b) The following items will not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of Section 4.11(a):

                  (1) any fees, compensation and other payments paid to any
         officer or employee pursuant to any employment agreement, employee or
         director benefit plan, officer and director indemnification agreement
         or any similar arrangement entered into by the Company or any of its
         Restricted Subsidiaries in the ordinary course of business;

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

                  (3) transactions with a Person (other than an Unrestricted
         Subsidiary of the Company) that is an Affiliate of the Company solely
         because the Company owns, directly or through a Restricted Subsidiary,
         an Equity Interest in, or controls, such Person;


                                       59

                  (4) payment of reasonable directors' fees to Persons who are
         not otherwise Affiliates of the Company;

                  (5) any issuance of Equity Interests (other than Disqualified
         Stock) of the Company to Affiliates of the Company;

                  (6) Restricted Payments that do not violate Section 4.07
         hereof.

                  (7) loans or advances to employees in the ordinary course of
         business not to exceed $2.0 million in the aggregate at any one time
         outstanding;

                  (8) sales (including a sale in exchange for a promissory note
         of or Equity Interest in such Accounts Receivable Subsidiary) of
         accounts receivable, related assets and the provision of billing,
         collection and other services in connection therewith, in each case, to
         an Accounts Receivable Subsidiary in connection with any Receivables
         Facility;

                  (9) transactions pursuant to any contract or agreement in
         effect on the date hereof, as the same may be amended, modified,
         extended or replaced from time to time, so long as any such contract or
         agreement as so amended, modified, extended or replaced is, taken as a
         whole, not materially less favorable to the Company and its Restricted
         Subsidiaries than under those agreements as described in the Offering
         Circular in the section "Certain Relationships and Related
         Transactions";

                  (10) any transaction or series of transactions between the
         Company or any Restricted Subsidiary and any of their Joint Ventures,
         provided that (a) such transaction or series of transactions is in the
         ordinary course of business between the Company or such Restricted
         Subsidiary and such Joint Venture, and (b) with respect to any such
         Affiliate Transaction involving aggregate consideration in excess of
         $5.0 million, such Affiliate Transaction complies with Section
         4.11(a)(1) hereof and such Affiliate Transaction has been approved by
         the Board of Directors; and

                  (11) Permitted Investments and Permitted Payments to Parent.

Section 4.12      Liens.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien, except Permitted Liens, to secure Indebtedness of any kind on
any asset now owned or hereafter acquired, unless all payments due under this
Indenture and the Notes are secured on an equal and ratable basis with the
obligations so secured (or, if such obligations are subordinated by their terms
to the Notes or the Note Guarantees, prior to the obligations so secured) until
such time as such obligations are no longer secured by a Lien.

Section 4.13      Corporate Existence.

         Subject to Articles 5 and 10 hereof, the Company shall do or cause to
be done all things necessary to preserve and keep in full force and effect (1)
its corporate existence, and the corporate, partnership or other existence of
each of its Restricted Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of the
Company or any such Restricted Subsidiary; and (2) the rights (charter and
statutory), licenses and franchises of the Company and its Restricted
Subsidiaries; provided, however, that the Company shall not be required to
preserve any such right, license or franchise, or the corporate, partnership or
other existence of any of its Restricted


                                       60

Subsidiaries, if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company and
its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not
adverse in any material respect to the Holders.

Section 4.14      Offer to Repurchase Upon Change of Control.

         (a) Upon the occurrence of a Change of Control, the Company will make
an offer (a "Change of Control Offer") to each Holder to repurchase all or any
part (equal to $1,000 or an integral multiple of $1,000) of such Holder's Notes
at a purchase price equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Additional Interest, if any, on the Notes
repurchased, if any, to the Change of Control Payment Date, subject to the
rights of Holders on the relevant record date to receive interest due on the
relevant interest payment date (the "Change of Control Payment"). Within 30 days
following any Change of Control, the Company will mail a notice to each Holder
describing the transaction or transactions that constitute the Change of Control
and stating:

                  (1) that the Change of Control Offer is being made pursuant to
         this Section 4.14 and that all Notes properly tendered will be accepted
         for payment;

                  (2) the purchase price and the purchase date, which shall be
         no earlier than 30 days and no later than 60 days from the date such
         notice is mailed (the "Change of Control Payment Date");

                  (3) that any Note not tendered will continue to accrue
         interest;

                  (4) that, unless the Company defaults in the payment of the
         Change of Control Payment, all Notes accepted for payment pursuant to
         the Change of Control Offer will cease to accrue interest after the
         Change of Control Payment Date, and the only remaining right of the
         Holder of such Note is to receive payment of the Change of Control
         Payment upon surrender of the Note so purchased to the Company or the
         Paying Agent;

                  (5) that Holders electing to have any Notes purchased pursuant
         to a Change of Control Offer will be required to surrender the Notes,
         with the form entitled "Option of Holder to Elect Purchase" on the
         reverse of the Notes completed, or transfer by book-entry transfer, to
         the Paying Agent at the address specified in the notice prior to the
         close of business on the third Business Day preceding the Change of
         Control Payment Date;

                  (6) that Holders will be entitled to withdraw their election
         if the Paying Agent receives, not later than the close of business on
         the second Business Day preceding the Change of Control Payment Date, a
         facsimile transmission or letter setting forth the name of the Holder,
         the principal amount of Notes delivered for purchase, and a statement
         that such Holder is withdrawing his election to have the Notes
         purchased; and

                  (7) that Holders whose Notes are being purchased only in part
         will be issued new Notes equal in principal amount to the unpurchased
         portion of the Notes surrendered (or transferred by book-entry
         transfer), which unpurchased portion must be equal to $1,000 in
         principal amount or an integral multiple thereof.

         The Company will comply with the provisions of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such provisions are applicable in connection with each repurchase of the
Notes pursuant to a Change of Control Offer. To the extent that the provisions
of any securities laws or regulations conflict with this Section 4.14, the
Company will comply


                                       61

with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under this Section 4.14 hereof by virtue of such
conflict.

         (b) On the Change of Control Payment Date, the Company will, to the
extent lawful:

                  (1) accept for payment all Notes or portions thereof properly
         tendered pursuant to the Change of Control Offer;

                  (2) deposit with the Paying Agent an amount equal to the
         Change of Control Payment in respect of all Notes or portions of Notes
         properly tendered; and

                  (3) deliver or cause to be delivered to the Trustee the Notes
         properly accepted together with an Officers' Certificate stating the
         aggregate principal amount of Notes or portions of Notes being
         purchased by the Company.

         The Paying Agent will promptly mail or deliver to each Holder of Notes
properly tendered the Change of Control Payment for such Notes, and the Trustee
will promptly authenticate and mail (or cause to be transferred by book entry)
to each Holder a new Note equal in principal amount to any unpurchased portion
of the Notes surrendered, if any; provided that each new Note will be in a
principal amount of $1,000 or an integral multiple thereof.

         (c) Notwithstanding anything to the contrary in this Section 4.14, the
Company will not be required to make a Change of Control Offer upon a Change of
Control if:

                  (1) a third party makes the Change of Control Offer in the
         manner, at the times and otherwise in compliance with the requirements
         set forth in this Section 4.14 hereof and purchases all Notes properly
         tendered and not withdrawn under the Change of Control Offer; or

                  (2) notice of redemption has been given pursuant to Section
         3.03 hereof, unless or until there is a default in payment of the
         applicable redemption price.

         (d) Other than as specifically provided in this Section 4.14, any
redemption pursuant to this Section 4.14 shall be made pursuant to the
provisions of Sections 3.05 and 3.06 hereof.

Section 4.15      Limitation on Sale and Leaseback Transactions.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, 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 that Restricted Subsidiary, as applicable,
         could have (a) incurred Indebtedness in an amount equal to the
         Attributable Debt relating to such sale and leaseback transaction under
         the Fixed Charge Coverage Ratio test in Section 4.09(a) hereof and (b)
         incurred a Lien to secure such Indebtedness pursuant to Section 4.12
         hereof;

                  (2) the gross cash proceeds of that sale and leaseback
         transaction are at least equal to the Fair Market Value, as determined
         in good faith by the Board of Directors and set forth in an Officers'
         Certificate delivered to the Trustee, of the property that is the
         subject of that sale and leaseback transaction; and


                                       62

                  (3) the transfer of assets in such sale and leaseback
         transaction is permitted by, and the Company applies the proceeds of
         such sale and leaseback transaction in compliance with, Sections 3.09
         and 4.10 hereof.

Section 4.16      Payments for Consent.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder for or as an inducement to any
consent, waiver or amendment of any of the terms or provisions of this Indenture
or the Notes unless such consideration is offered to be paid or agreed to be
paid to all Holders that consent, waive or agree to amend in the time frame set
forth in the solicitation documents relating to such consent, waiver or
agreement.

Section 4.17      Additional Note Guarantees.

         If the Company or any of its Restricted Subsidiaries acquires or
creates another Domestic Subsidiary after the date hereof, then the Company will
cause that newly acquired or created Domestic Subsidiary, unless such newly
acquired or created Domestic Subsidiary has been designated as an Unrestricted
Subsidiary under this Indenture, to become a Guarantor and execute a Note
Guarantee pursuant to a supplemental indenture in form and substance
satisfactory to the Trustee and deliver an Opinion of Counsel satisfactory to
the Trustee, to the Trustee within ten Business Days of the date on which it was
acquired or created to the effect that such supplemental indenture has been duly
authorized, executed and delivered by such Domestic Subsidiary and constitutes a
valid and binding agreement of such Domestic Subsidiary, enforceable against
such Domestic Subsidiary in accordance with its terms (subject to customary
exceptions). The form of such supplemental indenture is attached as Exhibit F
hereto.

Section 4.18      Designation of Restricted and Unrestricted Subsidiaries

         The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default. If a
Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate
Fair Market Value of all outstanding Investments owned by the Company and its
Restricted Subsidiaries in the Subsidiary designated as Unrestricted shall be
deemed to be an Investment made as of the time of the designation and will
reduce the amount available for Restricted Payments under Section 4.07 hereof or
under one or more clauses of the definition of Permitted Investments, as
determined by the Company. That designation shall only be permitted if the
Investment would be permitted at that time and if the Restricted Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary. The Board of
Directors may redesignate any Unrestricted Subsidiary to be a Restricted
Subsidiary if that redesignation would not cause a Default. If a Restricted
Subsidiary that is a Guarantor is designated an Unrestricted Subsidiary in
accordance with the terms of this covenant, such Note Guarantee will be
released.

Section 4.19       Accounts Receivable Facilities

         The Company or any of its Restricted Subsidiaries may sell (including a
sale in exchange for a promissory note of or Equity Interest in such Accounts
Receivable Subsidiary) at any time and from time to time, accounts receivable
and related assets to any Accounts Receivable Subsidiary; provided that the
aggregate consideration received in each such sale is at least equal to the
aggregate fair market value of the receivables sold.

predecessor Company shall not be relieved from the obligation to pay the
principal of and interest on the Notes in the case of a sale, assignment,
transfer, conveyance or other disposition of less than all of the Company's
assets.

                              DEFAULTS AND REMEDIES

Section 6.01      Events of Default.

         An "Event of Default" occurs if:

                  (1) there is a default for 30 days in the payment when due of
         interest or Additional Interest on the Notes;

                  (2) there is a default in the payment when due (at maturity,
         upon redemption or otherwise) of the principal of, or premium, if any,
         on the Notes;

                  (3) the Company or any of its Restricted Subsidiaries fails to
         comply with the provisions of Section 3.09, 4.10, 4.14 or 5.01 hereof;

                  (4) the Company or any Guarantor fails to comply with any
         other covenant or agreement in this Indenture or the Notes which shall
         not have been remedied within the specified period after written
         notice, as specified in the last paragraph of this Section 6.01;

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

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

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

         and, in each case, the principal amount of any such Indebtedness,
         together with the principal amount of any other such Indebtedness under
         which there has been a Payment Default or the


                                       65

         maturity of which has been so accelerated, aggregates $20.0 million or
         more and has not been discharged in full or such acceleration has not
         been rescinded or annulled within 30 days of such maturity or
         acceleration;

                  (6) a final judgment or final judgments for the payment of
         money are entered by a court or courts of competent jurisdiction
         against the Company or any of its Restricted Subsidiaries, which
         judgment or judgments are not paid, stayed or otherwise discharged for
         a period of 60 days after such judgment or judgments become final and
         non-appealable; provided that the aggregate of all such unpaid,
         unstayed or undischarged judgments that are not covered by indemnities
         or third party insurance as to which the Person giving such indemnity
         or such insurer has not disclaimed coverage exceeds $20.0 million; and

                  (7) the Company or any Restricted Subsidiary that is a
         Significant Subsidiary or any group of Restricted Subsidiaries that,
         taken as a whole, would constitute a Significant Subsidiary pursuant to
         or within the meaning of Bankruptcy Law:

                           (A) commences a voluntary case,

                           (B) consents to the entry of an order for relief
                  against it in an involuntary case,

                           (C) consents to the appointment of a custodian of it
                  or for all or substantially all of its property,

                           (D) makes a general assignment for the benefit of its
                  creditors; or

                  (8) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that remains unstayed and in effect for
         60 consecutive days and that:

                           (A) is for relief against the Company or any
                  Restricted Subsidiary that is a Significant Subsidiary or any
                  group of Restricted Subsidiaries that, taken as a whole, would
                  constitute a Significant Subsidiary as debtor in an
                  involuntary case;

                           (B) appoints a custodian of the Company or any
                  Restricted Subsidiary that is a Significant Subsidiary or any
                  group of Restricted Subsidiaries that, taken as a whole, would
                  constitute a Significant Subsidiary or for all or
                  substantially all of the property of the Company or any
                  Restricted Subsidiary that is a Significant Subsidiary or any
                  group of Restricted Subsidiaries that, taken as a whole, would
                  constitute a Significant Subsidiary; or

                           (C) orders the liquidation of the Company or any
                  Restricted Subsidiary that is a Significant Subsidiary or any
                  group of Restricted Subsidiaries that, taken as a whole, would
                  constitute a Significant Subsidiary;

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

         When a Default is cured, it ceases.


                                       66

         A Default under clause (4) of this Section 6.01 is not an Event of
Default until the Trustee notifies the Company, or the Holders of at least 25%
in principal amount of the then outstanding Notes notify the Company, and the
Trustee, of the Default, and the Company or the applicable Guarantor, as the
case may be, fails to cure the Default within 60 days after receipt of the
notice. The notice must specify the Default, demand that it be remedied and
state that the notice is a "Notice of Default."

Section 6.02      Acceleration.

         (a) In the case of an Event of Default specified in clause (7) or (8)
of Section 6.01 hereof, all outstanding Notes will become due and payable
immediately without further action or notice. If any other Event of Default
occurs and is continuing, the Trustee by notice to the Company or the Holders of
at least 25% in principal amount of the then outstanding Notes by notice to the
Company and the Trustee, may declare all the Notes to be due and payable. Upon
any such declaration, the Notes shall become due and payable immediately. The
Holders of a majority in aggregate principal amount of the then outstanding
Notes by written notice to the Trustee may on behalf of all of the Holders
rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal or premium, if any, interest or Additional
Interest, if any, that has become due solely because of the acceleration) have
been cured or waived.

         (b) If an Event of Default occurs by reason of any willful action or
inaction taken or not taken by or on behalf of the Company with the intention of
avoiding payment of the premium that the Company would have had to pay if the
Company then had elected to redeem the Notes pursuant to Section 3.07(b) (if
such Event of Default occurs prior to July 15, 2007) or Section 3.07(c) (if such
Event of Default occurs on or after July 15, 2007), then, upon acceleration of
the Notes, an equivalent premium shall also become and be immediately due and
payable, to the extent permitted by law.

         (c) Section 6.02(b) refers only to those times when the Company, while
solvent, voluntarily, knowingly, deliberately or intentionally avoids payment of
the premium referred to in Section 6.02(b) and is not intended to encompass
those situations in which such a payment of premium would render the Company
insolvent or force a bankruptcy, liquidation or reorganization of the Company,
or where non-payment is a result of financial distress or adverse financial
condition.

Section 6.03      Other Remedies.

         If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal and premium, if any,
interest and Additional Interest, if any, 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 of a Note in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

Section 6.04      Waiver of Past Defaults.

         Subject to Sections 6.07 and 9.02, Holders of not less than a majority
in aggregate principal amount of the then outstanding Notes by notice to the
Trustee may on behalf of the Holders of all of the Notes waive an existing
Default or Event of Default and its consequences hereunder (including, without
limitation, waivers obtained in connection with a tender offer or exchange offer
for, or purchases of, Notes or a solicitation of consents in respect of Notes),
except (1) a continuing Default or Event of


                                       67

Default in the payment of the principal of, or premium, if any, interest or
Additional Interest, if any, on any Note or (2) a continued Default in respect
of a provision that under Section 9.02 cannot be amended or supplemented without
the consent of each Holder affected. Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.

Section 6.05      Control by Majority.

         Holders of a majority in principal amount of the then outstanding Notes
may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture, that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

Section 6.06      Limitation on Suits.

         Subject to Section 6.07, a Holder of a Note may pursue a remedy with
respect to this Indenture or the Notes only if:

                  (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 then outstanding Notes make a written request to the Trustee to
         pursue the remedy;

                  (3) such Holder or Holders offer and, if requested, provide to
         the Trustee indemnity or security reasonably satisfactory to the
         Trustee against any loss, liability or expense;

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

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

         A Holder 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 of Notes to Receive Payment.

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

Section 6.08      Collection Suit by Trustee.

         If an Event of Default specified in Section 6.01(1) or (2) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name and
as trustee of an express trust against the Company or a Guarantor for the whole
amount of principal of, and premium, if any, interest and Additional Interest,
if any, remaining unpaid on the Notes and interest on overdue principal and, to
the extent lawful, interest


                                       68

and such further amount as shall be sufficient to cover the costs and expenses
of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel.

Section 6.09      Trustee May File Proofs of Claim.

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

                                    TRUSTEE

Section 7.01      Duties of Trustee.

         (a) If an Event of Default has occurred and is continuing, the Trustee
will exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in its exercise, as a prudent person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

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

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

                  (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, the Trustee will examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture.

         (c) The Trustee may not be relieved from liabilities 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 will not be liable for any error of judgment
         made in good faith by a Responsible Officer, unless it is proved that
         the Trustee was negligent in ascertaining the pertinent facts; and

                  (3) the Trustee will not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 6.05 hereof.

         (d) Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), and (c) of this Section 7.01.

         (e) No provision of this Indenture will require the Trustee to expend
or risk its own funds or incur any liability. The Trustee will be under no
obligation to exercise any of its rights and powers under this Indenture at the
request of any Holders, unless such Holder has offered to the Trustee security
and indemnity satisfactory to it against any loss, liability or expense.

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

Section 7.02      Rights of Trustee.

         (a) The Trustee may conclusively rely upon any document reasonably
believed by it to be genuine and to have been signed or presented by the proper
Person. The Trustee need not investigate any fact or matter stated in the
document.

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

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

         (d) The Trustee will not be liable for any action it takes or omits to
take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture.

demand, request, direction or notice from the Company or a Guarantor will be
sufficient if signed by an Officer of the Company or such Guarantor.

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

         (g) The Trustee is not required to take notice or deemed to have notice
of any Event of Default hereunder, except Events of Default under Section

knowledge thereof or has received notice in writing of such Event of Default
from the Company, any Guarantor or the Holders of at least 25% in aggregate
principal amount of the outstanding Notes, and in the absence of any such
notice, the Trustee may conclusively assume that no such Event of Default
exists.

to the performance of its duties or the exercise of its powers under this
Indenture.

         (i) In the event the Trustee receives inconsistent or conflicting
requests and indemnity from two or more groups of Holders of Notes, each
representing less than a majority in aggregate principal amount of the
outstanding Notes, pursuant to the provisions of this Indenture, the Trustee, in
its sole discretion, may determine what action, if any, shall be taken.

         (j) The Trustee's immunities and protections from liability and its
right to indemnification in connection with the performance of its duties under
this Indenture shall extend to the Trustee's officers, directors, agents,
attorneys and employees to the same extent as is applicable to the Trustee. Such
immunities and protections and right to indemnification, together with the
Trustee's right to


                                       71

compensation, shall survive the Trustee's resignation or removal, the defeasance
or discharge of this Indenture and final payment of the Notes.

         (k) The permissive right of the Trustee to take the actions permitted
by this Indenture shall not be construed as an obligation or duty to do so.

Section 7.03      Individual Rights of Trustee.

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

Section 7.04      Trustee's Disclaimer.

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

Section 7.05      Notice of Defaults.

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

Section 7.06      Reports by Trustee to Holders of the Notes.

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

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


                                       72

Section 7.07      Compensation and Indemnity.

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

         (b) The Company and the Guarantors will indemnify the Trustee against
any and all losses, liabilities or expenses incurred by it arising out of or in
connection with the acceptance or administration of its duties under this
Indenture, including the costs and expenses of enforcing this Indenture against
the Company and the Guarantors (including this Section 7.07) and defending
itself against any claim (whether asserted by the Company, the Guarantors or any
Holder or any other Person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder, except to the extent any
such loss, liability or expense may be attributable to its negligence or bad
faith. The Trustee will notify the Company promptly of any claim for which it
may seek indemnity. Failure by the Trustee to so notify the Company will not
relieve the Company or any of the Guarantors of their obligations hereunder. The
Company or such Guarantor will defend the claim and the Trustee will cooperate
in the defense. The Trustee may have separate counsel and the Company will pay
the reasonable fees and expenses of such counsel. Neither the Company nor any
Guarantor need pay for any settlement made without its consent, which consent

the Trustee will 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 and
interest on particular Notes. Such Lien will survive the satisfaction and
discharge of this Indenture.

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

         (f) The Trustee will comply with the provisions of TIA Section
313(b)(2) to the extent applicable.

Section 7.08      Replacement of Trustee.

hereby created by so notifying the Company in writing. The Holders of a majority
in principal amount of the then outstanding Notes may remove the Trustee by so

Trustee if:

         order for relief is entered with respect to the Trustee under any
         Bankruptcy Law;

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

                  (4) the Trustee becomes incapable of acting.

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

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

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

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

         Subject to Section 7.10, 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 will be the successor Trustee.

Section 7.10      Eligibility; Disqualification.

bank or banking association organized and doing business under the laws of the
United States of America or of any state thereof that is authorized under such
laws to exercise corporate trustee power, that is subject to supervision or
examination by federal or state authorities and that has a combined capital and
surplus of at least $100 million as set forth in its most recent published
annual report of condition.

requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to
TIA Section 310(b).

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01      Option to Effect Legal Defeasance or Covenant Defeasance.

         The Company may, at the option of its Board of Directors evidenced by a
Board Resolution set forth in an Officers' Certificate, at any time, elect to
have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article 8.

Section 8.02      Legal Defeasance and Discharge.

         Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company and each of the Guarantors will,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be deemed to have been discharged from their obligations with respect to all
outstanding Notes (including the Note Guarantees) on the date the conditions set
forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose,
Legal Defeasance means that the Company and the Guarantors will be deemed to
have paid and discharged the entire Indebtedness represented by the outstanding
Notes (including the Note Guarantees), which will thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 hereof and the other
Sections of this Indenture referred to in clauses (1) and (2) below, and to have
satisfied all their other obligations under such Notes, the Note Guarantees and
this Indenture (and the Trustee, on demand of and at the expense of the Company,
shall execute proper instruments acknowledging the same), except for the
following provisions which will survive until otherwise terminated or discharged
hereunder:

                  (1) the rights of Holders of outstanding Notes to receive
         payments in respect of the principal of, and premium, if any, interest
         and Additional Interest, if any, on such Notes when such payments are
         due from the trust referred to in Section 8.04 hereof;

                  (2) the Company's obligations with respect to such Notes under
         Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.10 and 4.02 hereof;

                  (3) the rights, powers, trusts, duties and immunities of the
         Trustee hereunder and the Company's obligations in connection
         therewith; and

                  (4) this Article 8.

         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, the Company and the Guarantors will, subject to
the satisfaction of the conditions set forth in Section 8.04 hereof, be released
from each of their obligations under the covenants contained in Sections 4.07,
4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18 and 4.19 hereof
and clause (4) of


                                       75

Section 5.01 hereof with respect to the outstanding Notes on and after the date
the conditions set forth in Section 8.04 hereof are satisfied (hereinafter,
"Covenant Defeasance"), and the Notes will 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 will continue to be deemed "outstanding" for all other purposes
hereunder (it being understood that such Notes will not be deemed outstanding
for accounting purposes). For this purpose, Covenant Defeasance means that, with
respect to the outstanding Notes and Note Guarantees, the Company and the
Guarantors may omit to comply with and will have no liability in respect of any
term, condition or limitation set forth in any such covenant, whether directly
or indirectly, by reason of any reference elsewhere herein to any such covenant
or by reason of any reference in any such covenant to any other provision herein
or in any other document and such omission to comply will not constitute a
Default or an Event of Default under Section 6.01 hereof, but, except as
specified above, the remainder of this Indenture and such Notes and Note
Guarantees will be unaffected thereby. In addition, upon the Company's exercise
under Section 8.01 hereof of the option applicable to this Section 8.03 hereof,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
Sections 6.01(3) through 6.01(5) hereof will not constitute Events of Default.

Section 8.04      Conditions to Legal or Covenant Defeasance.

         In order to exercise either Legal Defeasance or Covenant Defeasance
under either Sections 8.02 or 8.03 hereof:

         the case of clauses (y) and (z)) of a nationally recognized investment
         bank, appraisal firm or firm of independent public accountants, to pay
         the principal of, and premium, if any, interest and Additional
         Interest, if any, on the outstanding Notes on the Stated Maturity or on
         the applicable redemption date, as the case may be, and the Company
         must specify whether the Notes are being defeased to maturity or to a
         particular redemption date;

                  published by, the Internal Revenue Service a ruling; or

                           (B) since the date hereof, there has been a change in
                  the applicable federal income tax law,

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

                  (3) in the case of an election under Section 8.03 hereof, the
         Company must deliver to the Trustee an Opinion of Counsel reasonably
         acceptable to the Trustee confirming that the Holders of the
         outstanding Notes will not recognize income, gain or loss for federal
         income tax purposes as a result of such Covenant Defeasance and will be
         subject to federal income tax on the same amounts, in the same manner
         and at the same times as would have been the case if such Covenant
         Defeasance had not occurred;


                                       76

                  (4) no Default or Event of Default shall have occurred and be

         deposit);

                  (5) such Legal Defeasance or Covenant Defeasance will not
         result in a breach or violation of, or constitute a default under, any
         material agreement or instrument (other than this Indenture) 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 must deliver to the Trustee an Officers'
         Certificate stating that the deposit was not made by the Company with
         the intent of preferring the Holders over any other creditors of the

         any other creditors of the Company or others; and

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

Section 8.05      Deposited Money and Government Securities to be Held in Trust;
Other Miscellaneous Provisions.

         Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes
will be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company or any of its Domestic
Subsidiaries acting as Paying Agent) as the Trustee may determine, to the
Holders of such Notes of all sums due and to become due thereon in respect of
principal of, and premium, if any, interest and Additional Interest, if any, but
such money need not be segregated from other funds except to the extent required
by law.

         The Company will pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes.

         Notwithstanding anything in this Article 8 to the contrary, the Trustee
will deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.04(1) hereof), are in excess of the amount thereof that would then be required
to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06      Repayment to Company.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, or premium, if
any, interest or Additional Interest, if any, on any Note and remaining
unclaimed for two years after such principal and premium, if any, interest and
Additional Interest, if any, has become due and payable shall be paid to the
Company on its request or (if then held by the Company) will be discharged from
such trust; and the Holder of such Note will thereafter


                                       77

be permitted to look only to the Company for payment thereof as general
creditors unless an applicable abandoned property law designates another Person,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, will thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which will not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

Section 8.07      Reinstatement.

         If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's and any Guarantor's obligations under this
Indenture and the Notes and the Note Guarantees will be revived and reinstated
as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 8.02 or 8.03 hereof, as the case may be; provided,
however, that, if the Company or any Guarantor makes any payment of principal
of, or premium, if any, interest or Additional Interest, if any, on any Note
following the reinstatement of its obligations, the Company or such Guarantor
will be subrogated to the rights of the Holders of such Notes to receive such
payment from the money held by the Trustee or Paying Agent.

                                   ARTICLE 9.
                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01      Without Consent of Holders of Notes.

         Notwithstanding Section 9.02 of this Indenture, the Company, the
Guarantors and the Trustee may amend or supplement this Indenture or the Notes
without the consent of any Holder of a Note:

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

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

                  (3) to provide for the assumption of the Company's or a
         Guarantor's obligations to the Holders by a successor to the Company or
         such Guarantor pursuant to Article 5 or Article 10 hereof;
         respectively;

                  (4) to make any change that would provide any additional
         rights or benefits to the Holders or that does not adversely affect in
         any material respect the legal rights hereunder of any Holder;

                  (5) to provide any security for, any guarantees of or any
         additional obligors on the Notes or the Note Guarantees, or to confirm
         and evidence the release, termination or discharge of any such security
         or guarantee when such release, termination or discharge is permitted
         by this Indenture;

                  (6) to comply with requirements of the SEC in order to effect
         or maintain the qualification of this Indenture under the TIA; or


                                       78

                  (7) to conform the text of this Indenture or the Notes to any
         provision in the Offering Circular in the section "Description of
         Notes" to the extent that such provision in the "Description of Notes"
         was intended to be a substantially verbatim recitation of a provision
         of this Indenture, the Note Guarantees or the Notes.

         Upon the request of the Company accompanied by a Board Resolution
authorizing the execution of any such amended or supplemental Indenture, and
upon receipt by the Trustee of the documents described in Section 9.06 hereof,
the Trustee will join with the Company and the Guarantors in the execution of
any amended or supplemental Indenture authorized or permitted by the terms of
this Indenture and to make any further appropriate agreements and stipulations
that may be therein contained, but the Trustee will not be obligated to enter
into such amended or supplemental Indenture that affects its own rights, duties
or immunities under this Indenture or otherwise, in which case the Trustee may
in its discretion, but will not be obligated to, enter into such amended or
supplemental Indenture.

Section 9.02      With Consent of Holders of Notes.

         Except as provided below in this Section 9.02, the Company, the
Guarantors and the Trustee may amend or supplement this Indenture (including,
without limitation, Section 3.09, 4.10 and 4.14 hereof), the Note Guarantees and
the Notes with the consent of the Holders of at least a majority in principal
amount of the Notes then outstanding as a single class (including, without
limitation, consents obtained in connection with a tender offer or exchange
offer for, or purchase of, the Notes).

         Upon the request of the Company accompanied by a Board Resolution
authorizing the execution of any such amended or supplemental Indenture, and
upon the filing with the Trustee of evidence satisfactory to the Trustee of the
consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of
the documents described in Section 9.06 hereof, the Trustee will join with the
Company in the execution of such amended or supplemental Indenture unless such
amended or supplemental Indenture directly affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise, in which case the
Trustee may in its discretion, but will not be obligated to, enter into such
amended or supplemental Indenture.

         It is not be necessary for the consent of the Holders of Notes under
this Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

         After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company will mail to the Holders of Notes affected
thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any defect therein, will not,
however, in any way impair or affect the validity of any such amended or
supplemental Indenture or waiver. The Holders of a majority in aggregate
principal amount of the Notes then outstanding voting as a single class may
waive compliance in a particular instance by the Company with any provision of
this Indenture or the Notes (including, without limitation, waivers obtained in
connection with a tender offer or exchange offer for, or purchases of, Notes or
a solicitation of consents in respect of Notes). However, without the consent of
each Holder affected, an amendment, supplement or waiver under this Section 9.02
may not (with respect to any Notes held by a non-consenting Holder):

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


                                       79

                  (2) reduce, or change the Stated Maturity of, the principal of
         any Note, change the date on which any of the Notes may be subject to
         redemption or repurchase or reduce the redemption or repurchase price
         of the Notes;

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

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

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

                  (6) make any change in the provisions of this Indenture
         relating to waivers of past Defaults or Events of Default or the rights
         of Holders to receive payments of principal of, or premium, if any,
         interest or Additional Interest, if any, on the Notes;

                  (7) waive a redemption payment with respect to any Note (other
         than a payment required by Sections 3.09, 4.10 or 4.14 hereof);

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

                  (9) make any change in Section 6.04 or 6.07 hereof or in this
         sentence of Section 9.02.

Section 9.03      Compliance with Trust Indenture Act.

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

Section 9.04      Revocation and Effect of Consents.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by such 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
its Note if the Trustee receives written notice of revocation before a date and
time therefor identified by the Company in a notice furnished to such Holder in
accordance with the terms of this Indenture or, if no such date and time shall
be identified, the date the amendment, supplement or waiver becomes effective.
An amendment, supplement 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
(which need not comply with TIA Section 316(c)) for the purpose of determining
the Holders entitled to consent to any amendment, supplement or waiver or to
take any other action under this Indenture. If a record date is fixed, then
notwithstanding the provisions of the immediately preceding paragraph, those
Persons who were Holders at such record date (or their duly designated proxies),
and only those Persons, shall be entitled to consent to such amendment,
supplement or waiver or to revoke any consent previously given, whether or not
such Persons continue to be Holders after such record date. No consent shall be
valid or effective for more than 90 days after such record date unless consents
from Holders of the principal amount of Notes


                                       80

required hereunder for such amendment, supplement or waiver to be effective
shall have also been given and not revoked within such 90-day period.

         After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it is of the type described in any of clauses (1)
through (9) of Section 9.02 hereof. In such case, the amendment, supplement or
waiver shall bind each Holder who has consented to it and every subsequent
Holder that evidences the same debt as the consenting Holder's Note.

Section 9.05      Notation on or Exchange of Notes.

         If an amendment or supplement changes the terms of a Note, the Company
may require the Holder of such Note to deliver such Note to the Trustee. The
Trustee may place an appropriate notation about an amendment, supplement or
waiver on any Note thereafter authenticated. The Company, in exchange for all
Notes, may issue and the Trustee shall, upon receipt of an Authentication Order,
authenticate new Notes that reflect the amendment, supplement or waiver.

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

Section 9.06      Trustee to Sign Amendments, etc.

         The Trustee will sign any amended or supplemental Indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. If it does,
the Trustee may, but need not sign it. In executing any amended or supplemental
Indenture, the Trustee will be entitled to receive and (subject to Section 7.01
hereof) will be fully protected in relying upon, in addition to any documents
required by Section 12.04 hereof, an Officers' Certificate and an Opinion of
Counsel stating that the execution of such amended or supplemental Indenture is
authorized or permitted by this Indenture.

                                  ARTICLE 10.
                                 NOTE GUARANTEES

Section 10.01     Guarantee.

         (a) Subject to this Article 10, each of the Guarantors hereby, jointly
and severally, unconditionally guarantees to each Holder of a Note authenticated
and delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes or
the obligations of the Company hereunder or thereunder, that:

                  (1) the principal of, and premium, if any, interest and
         Additional Interest, if any, on the Notes will be promptly paid in full
         when due, whether at maturity, by acceleration, redemption or
         otherwise, and interest on the overdue principal of and interest on the
         Notes, if any, if lawful, and all other payment obligations of the
         Company to the Holders or the Trustee hereunder or thereunder will be
         promptly paid in full or performed, all in accordance with the terms
         hereof and thereof; and

                  (2) in case of any extension of time of payment or renewal of
         any Notes or any of such other payment obligations, that same will be
         promptly paid in full when due or performed in accordance with the
         terms of the extension or renewal, whether at stated maturity, by
         acceleration or otherwise.


                                       81

         Failing payment when due of any amount so guaranteed or any performance
so guaranteed for whatever reason, the Guarantors will be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

         (b) The Guarantors hereby agree that their obligations hereunder will
be, to the extent permitted by law, unconditional, irrespective of the validity,
regularity or enforceability of the Notes or this Indenture, the absence of any
action to enforce the same, any waiver or consent by any Holder with respect to
any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of a guarantor.
To the extent permitted by law, each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first
against the Company, protest, notice and all demands whatsoever and, subject to
Article 8, covenant that this Note Guarantee will not be discharged except by
complete performance of the obligations contained in the Notes and this
Indenture.

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

         (d) Each Guarantor agrees that it will not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each
Guarantor further agrees that, as between the Guarantors, on the one hand, and
the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 hereof
for the purposes of this Note Guarantee, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (2) in the event of any declaration of acceleration of
such obligations as provided in Article 6 hereof, such obligations (whether or
not due and payable) will forthwith become due and payable by the Guarantors for
the purpose of this Note Guarantee. The Guarantors will have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right
does not impair the rights of the Holders under the Note Guarantee.

         (e) In the event of a default in the payment of principal of, or
premium, if any, interest or Additional Interest, if any, on any Note when and
as the same shall become due, whether at maturity, by acceleration, redemption
or otherwise, or in the event of a default in the payment of any interest on the
overdue principal of or interest on such Note, if any, if lawful, or any other
payment obligation of the Company to the Holder of such Note or the Trustee
hereunder or thereunder, each of the Trustee and such Holder shall have the
right to proceed first and directly against a Guarantor under this Indenture
without first proceeding against the Company or exhausting any other remedies
which the Trustee or such Holder may have and without resorting to any other
security held by it.

         (f) The Trustee shall have the right, power and authority to do all
things it deems necessary or advisable to enforce the provisions of this
Indenture relating to the Note Guarantee and to protect the interests of the
Holders of the Notes and, in the event of a default in the payment of principal
of, or premium, if any, interest or Additional Interest, if any, on any Note
when and as the same shall become due, whether at maturity, by acceleration,
redemption or otherwise, or in the event of a default in the payment of any
interest on the overdue principal of or interest on such Note, if any, if
lawful, or any other payment obligation of the Company to the Holder of such
Note or the Trustee hereunder or thereunder, the Trustee may institute or appear
in such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any of its rights and the rights of the
Holders, whether for the


                                       82

specific enforcement of any covenant or agreement in this Indenture relating to
the Note Guarantee or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy. Without limiting the generality of the
foregoing, in the event of a default in the payment of principal of, or premium,
if any, interest or Additional Interest, if any, on any Note when due, the
Trustee may institute a judicial proceeding for the collection of the sums so
due and unpaid, and may prosecute such proceeding to judgment or final decree,
and may enforce the same against a Guarantor and collect the moneys adjudged or
decreed to be payable in the manner provided by law out of the property of such
Guarantor, wherever situated.

Section 10.02     Limitation on Guarantor Liability.

         Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Note Guarantee of
such Guarantor not constitute a fraudulent transfer or conveyance for purposes
of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act or any similar federal or state law to the extent applicable to any
Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders
and each Guarantor hereby irrevocably agree that the obligations of such
Guarantor will be limited to the maximum amount that will, after giving effect
to such maximum amount and all other contingent and fixed liabilities of such
Guarantor that are relevant under such laws, and after giving effect to any
collections from, rights to receive contribution from or payments made by or on
behalf of any other Guarantor in respect of the obligations of such other
Guarantor under this Article 10, result in the obligations of such Guarantor
under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03     Execution and Delivery of Note Guarantee.

         To evidence its Note Guarantee set forth in Section 10.01, each
Guarantor hereby agrees that a notation of such Note Guarantee substantially in
the form attached as Exhibit E hereto will be endorsed by an Officer of such
Guarantor on each Note authenticated and delivered by the Trustee and that this
Indenture will be executed on behalf of such Guarantor by one of its Officers.

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

         If an Officer whose signature is on this Indenture or on the Note
Guarantee no longer holds that office at the time the Trustee authenticates the
Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid
nevertheless.

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

         In the event that the Company creates or acquires any Domestic
Subsidiary after the date of this Indenture, if required by Section 4.17 hereof,
the Company will cause such Domestic Subsidiary to comply with the provisions of
Section 4.17 hereof and this Article 10, to the extent applicable.

Section 10.04     Guarantors May Consolidate, etc., on Certain Terms.

         (a) Except as otherwise provided in Section 10.05, no Guarantor may
sell or otherwise dispose of all or substantially all of its assets to, or
consolidate with or merge with or into (whether or not such Guarantor is the
surviving Person) another Person, other than the Company or another Guarantor,
unless:


                                       83

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

                  (2) either:

                           (i) the Person acquiring the property in any such
         sale or disposition or the Person formed by or surviving any such
         consolidation or merger (in each case if other than the Guarantor)
         assumes all the obligations of that Guarantor under this Indenture and
         its Note Guarantee pursuant to a supplemental indenture satisfactory to
         the Trustee and under the Registration Rights Agreement; or

                           (ii) if applicable, the Net Proceeds of such sale or
         other disposition are applied in accordance with the applicable
         provisions of this Indenture, including, without limitation, Section
         4.10 hereof.

         (b) Upon any consolidation or merger, or any sale or other disposition
of all or substantially all of the assets of, a Guarantor in a transaction that
is subject to, and that complies with the provisions of, Section 10.04(a)
hereof, the successor Person formed by such consolidation or into or with which
such Guarantor is merged or to which such sale or other disposition is made
shall succeed to, and be substituted for (so that from and after the date of
such consolidation, merger, sale, lease, conveyance or other disposition, the
provisions of this Indenture referring to the applicable "Guarantor" shall refer
instead to the successor Person and not to such Guarantor), and may exercise
every right and power of such Guarantor under this Indenture and its Note
Guarantee with the same effect as if such successor Person had been named as a
Guarantor herein and the predecessor Guarantor shall be released from all
obligations under this Indenture and its Note Guarantee. Such successor Person
thereupon may cause to be signed any or all of the Note Guarantees to be
endorsed upon all of the Notes issuable hereunder which theretofore shall not
have been signed by the Company and delivered to the Trustee. All the Note
Guarantees so issued will in all respects have the same legal rank and benefit
under this Indenture as the Note Guarantees theretofore and thereafter issued in
accordance with the terms of this Indenture as though all of such Note
Guarantees had been issued at the date of the execution hereof.

         Except as set forth in Articles 4 and 5 hereof, and notwithstanding
Section 10.04(a)(2) and (b) hereof, nothing contained in this Indenture or in
any of the Notes will prevent any consolidation or merger of a Guarantor with or
into the Company or another Guarantor, or will prevent any sale or other
disposition of all or substantially all of the assets of a Guarantor to the
Company or another Guarantor.

Section 10.05     Releases Following Sale of Assets.

         In the event of any 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 Capital Stock of any
Guarantor, in each case, to a Person that is not (either before or after giving
effect to such transactions) the Company or a Restricted Subsidiary of the
Company, then such Guarantor (in the event of a sale or other disposition, by
way of merger, consolidation or otherwise, of all of the Capital Stock of such
Guarantor) or the Person acquiring the property (in the event of a sale or other
disposition of all or substantially all of the assets of such Guarantor) will be
released and relieved of any obligations under its Note Guarantee; provided that
the Net Proceeds of such sale or other disposition are applied in accordance
with the applicable provisions of this Indenture, including without limitation
Section 4.10 hereof. Upon delivery by the Company to the Trustee of an Officers'
Certificate and an Opinion of Counsel to the effect that such sale or other
disposition was made by the Company in accordance with the provisions of this
Indenture, including without limitation Section 4.10 hereof, the Trustee will

any documents reasonably required in order to evidence the release of any
Guarantor from its obligations under its Note Guarantee.

         Any Guarantor not released from its obligations under its Note
Guarantee will remain liable for the full amount of principal of and interest on
the Notes and for the other obligations of any Guarantor under this Indenture to
the extent provided in this Article 10.

                                  ARTICLE 11.
                           SATISFACTION AND DISCHARGE

Section 11.01     Satisfaction and Discharge.

         This Indenture will be discharged and will cease to be of further
effect as to all Notes and Note Guarantees issued hereunder, when:

                  (1) either:

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

                           (b) all Notes that have not been delivered to the
         Trustee for cancellation have become due and payable by reason of the
         mailing of a notice of redemption or otherwise or will become due and
         payable within one year and the Company or any Guarantor has
         irrevocably deposited or caused to be deposited with the Trustee as
         trust funds in trust solely for the benefit of the Holders, cash in
         U.S. dollars, non-callable Government Securities, or a combination of
         both, in such amounts as will be sufficient with consideration of any
         reinvestment of interest, to pay and discharge the entire indebtedness
         on the Notes not delivered to the Trustee for cancellation for the
         principal of, and premium, if any, interest and Additional Interest, if
         any, to the date of maturity or redemption;

                  (2) no Default or Event of Default has occurred and is
         continuing on the date of such deposit or will occur as a result of
         such deposit (other than a Default or Event of Default resulting from
         the borrowing of funds to be applied to such deposit) and such deposit
         will not result in a breach or violation of, or constitute a default
         under, any other instrument to which the Company or any Guarantor is a
         party or by which the Company or any Guarantor is bound;

                  (3) the Company or any Guarantor has paid or caused to be paid
         all sums payable by it under this Indenture; and

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

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

         Notwithstanding the satisfaction and discharge of this Indenture, if
money has been deposited with the Trustee pursuant to subclause (b) of clause
(1) of this Section 11.01, the provisions of Section 11.02 and Section 8.06 will
survive. In addition, nothing in this Section 11.01 will be deemed to


                                       85

discharge those provisions of Section 7.07 hereof, that, by their terms, survive
the satisfaction and discharge of this Indenture.

Section 11.02     Application of Trust Money.

         Subject to the provisions of Section 8.06, all money and non-callable
Government Securities (including the proceeds therefrom) deposited with the
Trustee pursuant to Section 11.01 shall be held in trust and applied by it, in
accordance with the provisions of the Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company or any of its
Domestic Subsidiaries acting as Paying Agent) as the Trustee may determine, to
the Persons entitled thereto, of the principal (and premium, if any) and
interest for whose payment such money has been deposited with the Trustee; but
such money need not be segregated from other funds except to the extent required
by law.

         If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 11.01 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 any Guarantor's obligations under this Indenture and the Notes and
the Note Guarantees shall be revived and reinstated as though no deposit had
occurred pursuant to Section 11.01 until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance with Section 11.01;
provided that if the Company or any Guarantor has made any payment of principal
of, or premium, if any, interest or Additional Interest, if any, on any Notes
following the reinstatement of its obligations, the Company or such Guarantor
shall be subrogated to the rights of the Holders of such Notes to receive such
payment from the money or Government Securities held by the Trustee or Paying
Agent.

                                   ARTICLE 12.

reason of any other cause, it shall be impossible to mail any notice required by
this Indenture, then such method of notification as shall be made with the
approval of the Trustee shall constitute a sufficient mailing of such notice.

         Holders may communicate pursuant to TIA Section 312(b) with other
Holders with respect to their rights under this Indenture or the Notes. The

Section 12.04     Certificate and Opinion as to Conditions Precedent.

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

         satisfactory to the Trustee (which must include the statements set
         forth in Section 12.05 hereof) stating that, in the opinion of the
         signers, all conditions precedent and covenants, if any, provided for

Indenture or the Note Guarantees or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder by accepting a Note

waive liabilities under the federal securities laws.

         This Note is one of a duly authorized issue of 8-3/4% Senior Notes due
2011 of Westlake Chemical Corporation, a Delaware corporation (the "Company").
Capitalized terms used herein have the meanings assigned to them in the
Indenture referred to below unless otherwise indicated.

                  (1) INTEREST. The Company promises to pay interest on the
         principal amount of this Note at 8-3/4% per annum from July 31, 2003
         until maturity and shall pay the Additional Interest, if any, payable
         pursuant to Section 6 of the Registration Rights Agreement referred to
         below. The Company will pay interest and Additional Interest, if any,
         semi-annually in arrears on January 15 and July 15 of each year, or if
         any such day is not a Business Day, on the next succeeding Business Day
         (each, an "Interest Payment Date"). Interest on the Notes will accrue
         from the most recent date to which interest has been paid or, if no
         interest has been paid, from July 31, 2003; provided that if there is
         no existing Default in the payment of interest, and if this Note is
         authenticated between a record date referred to on the face hereof and
         the next succeeding Interest Payment Date, interest shall accrue from
         such next succeeding Interest Payment Date; provided, further, that the
         first Interest Payment Date shall be January 15, 2004. The Company will
         pay interest (including post-petition interest in any proceeding under
         any Bankruptcy Law) on overdue principal and premium, if any, from time
         to time at a rate that is 1% per annum in excess of the interest rate
         then in effect to the extent lawful; it will pay interest (including
         post-petition interest in any proceeding under any Bankruptcy Law) on
         overdue installments of interest and Additional Interest, if any
         (without regard to any applicable grace periods) from time to time at
         the same rate to the extent lawful. Interest will be computed on the
         basis of a 360-day year of twelve 30-day months.

                  (2) METHOD OF PAYMENT. The Company will pay interest on the
         Notes (except defaulted interest) and Additional Interest, if any, to
         the Persons who are registered Holders of Notes at the close of
         business on the January 1 or July 1 next preceding the Interest Payment
         Date, even if such Notes are canceled after such record date and on or
         before such Interest Payment Date, except as provided in Section 2.12
         of the Indenture with respect to defaulted interest. The Notes will be
         payable as to principal and premium, if any, interest and Additional
         Interest, if any, at the office or agency of the Company maintained for
         such purpose within the City and State of New York, or, at the option
         of the Company, payment of interest and Additional Interest, if any,
         may be made by check mailed to the Holders at their addresses set forth
         in the register of Holders maintained by the Registrar; provided that
         payment by wire transfer of immediately available funds will be
         required with respect to principal of, and premium, if any, interest
         and Additional Interest, if any, on all Global Notes and any other
         Notes with any aggregate principal amount in excess of $1,000,000 the
         Holder of which has provided wire transfer instructions to the Company
         or the Paying Agent. Such payment will be in such coin or currency of
         the United States of America as at the time of payment is legal tender
         for payment of public and private debts.

                  (3) PAYING AGENT AND REGISTRAR. Initially, JPMorgan Chase
         Bank, the Trustee under the Indenture, will act as Paying Agent and
         Registrar. The Company may change any


                                      A1-2

         Paying Agent or Registrar without notice to any Holder. The Company or
         any of its Domestic Subsidiaries may act in any such capacity.

                  (4) INDENTURE. The Company issued the Notes under an Indenture
         dated as of July 31, 2003 (the "Indenture") among the Company, the
         Guarantors and the Trustee. The terms of the Notes include those stated
         in the Indenture and those made part of the Indenture by reference to
         the Trust Indenture Act of 1939, as amended (the "TIA"). The Notes are
         subject to all such terms, and Holders are referred to the Indenture
         and the TIA for a statement of such terms. To the extent any provision
         of this Note conflicts with the express provisions of the Indenture,
         the provisions of the Indenture shall govern and be controlling. The
         Notes are general unsecured obligations of the Company and are
         initially issued in an aggregate principal amount of $380,000,000. The
         Company may, subject to the covenants set forth in the Indenture, issue
         Additional Notes from time to time without the consent of the Holders.
         The Notes initially issued and any Additional Notes subsequently issued
         under the Indenture will be treated as a single class for all purposes
         of the Indenture, including, without limitation, with respect to
         waivers, amendments, supplements, redemptions and offers to purchase.

                  (5) OPTIONAL REDEMPTION.

         (a) Except as set forth in subparagraphs (b) and (c) of this Paragraph
5, the Company will not have the option to redeem the Notes prior to July 15,
2007. On or after July 15, 2007, the Company will have the option to redeem the
Notes, in whole or in part, upon not less than 30 nor more than 60 days' notice,
at the redemption prices (expressed as percentages of principal amount) set
forth below plus accrued and unpaid interest and Additional Interest, if any, on
the Notes redeemed, to the applicable redemption date, if redeemed during the
twelve-month period beginning on July 15 of the years indicated below, subject
to the rights of Holders on the relevant record date to receive interest on the
relevant Interest Payment Date:



        Year                                                Percentage
        ----                                                ----------
                                                         
        2007............................................     104.375%
        2008............................................     102.971%
        2009............................................     101.458%
        2010 and thereafter.............................     100.000%


         (b) Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, at any time on or prior to July 15, 2007, the Company may on any
one or more occasions redeem up to 35% of the aggregate principal amount of
Notes issued under the Indenture with the net cash proceeds of one or more
Public Equity Offerings at a redemption price equal to 108.75% of the aggregate
principal amount plus accrued and unpaid interest and Additional Interest, if
any, to the redemption date thereof; provided that at least 65% in aggregate
principal amount of the Notes issued under the Indenture remains outstanding
immediately after the occurrence of such redemption and that such redemption
occurs within 60 days of the date of the closing of such Public Equity Offering.

         (c) Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, at any time prior to July 15, 2007, the Company may also redeem all
or a part of the Notes at a redemption price equal to 100% of the principal
amount of Notes redeemed plus the Applicable Premium as of, and accrued and
unpaid interest and Additional Interest, if any, to the redemption date, subject
to the rights of Holders on the relevant record date to receive interest due on
the relevant Interest Payment Date. "Applicable Premium" means, with respect to
any Note on any redemption date, the greater of (1) 1.0% of the principal amount
of the Note or (2) the excess, if any, of (a) the present value on such
redemption date of


                                      A1-3

(i) the redemption price of the note at July 15, 2007 (such redemption price
being set forth in paragraph 5(a)) plus (ii) all required interest payments due
on the Note through July 15, 2007 (excluding accrued but unpaid interest to the
redemption date), computed using a discount rate equal to the Treasury Rate as
of such redemption date plus 50 basis points, over (b) the principal amount of
the Note. "Treasury Rate" means, as of any redemption date, the yield to
maturity as of such redemption date of United States Treasury securities with a
constant maturity (as compiled and published in the most recent Federal Reserve
Statistical Release H.15 (519) that has become publicly available at least two
Business Days prior to the redemption date (or, if such Statistical Release is
no longer published, any publicly available source of similar market data)) most
nearly equal to the period from the redemption date to July 15, 2007; provided,
however, that if the period from the redemption date to July 15, 2007, is less
than one year, the weekly average yield on actually traded United States
Treasury securities adjusted to a constant maturity of one year shall be used.

                  (6) MANDATORY REDEMPTION.

         The Company will not be required to make mandatory redemption or
sinking fund payments with respect to the Notes.

                  (7) REPURCHASE AT OPTION OF HOLDER.

                           (a) If there is a Change of Control, the Company will
         be required to make an offer (a "Change of Control Offer") to each
         Holder to repurchase all or any part (equal to $1,000 or an integral
         multiple thereof) of such Holder's Notes at a purchase price equal to
         101% of the aggregate principal amount thereof plus accrued and unpaid
         interest and Additional Interest, if any on the Notes repurchased, if
         any, to the Change of Control Payment Date, subject to the rights of
         Holders on the relevant record date to receive interest due on the
         relevant Interest Payment Date (the "Change of Control Payment").
         Within 30 days following any Change of Control, the Company will mail a
         notice to each Holder setting forth the procedures governing the Change
         of Control Offer as required by the Indenture.

                           (b) If the Company or a Restricted Subsidiary
         consummates any Asset Sales, within ten days of each date on which the
         aggregate amount of Excess Proceeds exceeds $15.0 million, the Company
         will commence an offer to all Holders of Notes and all holders of other
         Pari Passu Indebtedness containing provisions similar to those set
         forth in the Indenture with respect to offers to purchase or redeem
         with the proceeds of sales of assets (an "Asset Sale Offer") to
         purchase the maximum principal amount of Notes and such other Pari
         Passu Indebtedness that may be purchased out of the Excess Proceeds at
         an offer price in cash in an amount equal to 100% of the principal
         amount thereof plus accrued and unpaid interest and Additional Interest
         thereon, if any, to the date of purchase, in accordance with the
         procedures set forth in the Indenture. If any Excess Proceeds remain
         after consummation of an Asset Sale Offer, the Company may use such
         Excess Proceeds for any purpose not otherwise prohibited by the
         Indenture. If the aggregate principal amount of Notes and other Pari
         Passu Indebtedness tendered into such Asset Sale Offer exceeds the
         amount of Excess Proceeds, the Trustee shall select the Notes and such
         other Pari Passu Indebtedness to be purchased on a pro rata basis based
         on the principal amount of Notes and such other Pari Passu Indebtedness
         tendered. Holders of Notes that are the subject of an offer to purchase
         will receive an Asset Sale Offer from the Company prior to any related
         purchase date and may elect to have such Notes purchased by completing
         the form entitled "Option of Holder to Elect Purchase" on the reverse
         of this Note and otherwise complying with the procedures set forth in
         the Indenture. Upon completion of each Asset Sale Offer, the amount of
         Excess Proceeds shall be reset at zero.


                                      A1-4

                  (8) NOTICE OF REDEMPTION. Notice of redemption will be mailed
         at least 30 days but not more than 60 days before the redemption date
         to each Holder whose Notes are to be redeemed at its registered
         address. Notes in denominations larger than $1,000 may be redeemed in
         part but only in whole multiples of $1,000, unless all of the Notes
         held by a Holder are to be redeemed. On and after the redemption date
         interest ceases to accrue on Notes or portions thereof called for
         redemption.

                  (9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in
         registered form without coupons in denominations of $1,000 and integral
         multiples of $1,000. The transfer of Notes may be registered and Notes
         may be exchanged as provided in the Indenture. The Registrar and the
         Trustee may require a Holder, among other things, to furnish
         appropriate endorsements and transfer documents and the Company may
         require a Holder to pay any taxes and other governmental charges
         required by law or permitted by the Indenture. The Company need not
         exchange or register the transfer of any Note or portion of a Note
         selected for redemption, except for the unredeemed portion of any Note
         being redeemed in part. Also, the Company need not exchange or register
         the transfer of any Note for a period of 15 days before a selection of
         Notes to be redeemed.

                  (10) PERSONS DEEMED OWNERS. The registered Holder of a Note
         may be treated as its owner for all purposes.

                  (11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
         exceptions and limitations, the Indenture, the Note Guarantees or the
         Notes may be amended or supplemented with the consent of the Holders of
         at least a majority in principal amount of the then outstanding Notes,
         voting as a single class, and any existing default or compliance with
         any provision of the Indenture, the Note Guarantees or the Notes may be
         waived with the consent of the Holders of a majority in principal
         amount of the then outstanding Notes, voting as a single class. Without
         the consent of any Holder of a Note, the Indenture or the Notes may be
         amended or supplemented to cure any ambiguity, defect or inconsistency,
         to provide for uncertificated Notes in addition to or in place of
         certificated Notes, to provide for the assumption of the Company's or a
         Guarantor's obligations to Holders of the Notes in case of a merger or
         consolidation or a transfer of all or substantially all of its assets,
         to make any change that would provide any additional rights or benefits
         to the Holders of the Notes or that does not adversely affect in any
         material respect the legal rights under the Indenture of any such
         Holder, to provide any security for, any guarantees of or any
         additional obligors on the Notes or the Note Guarantees, or to confirm
         and evidence the release, termination or discharge of any such security
         or guarantee when such release, termination or discharge is permitted
         by this Indenture, to comply with the requirements of the SEC in order

         in the Offering Circular relating to the initial issuance of the Notes
         in the section "Description of Notes" to the extent that such provision
         in the "Description of Notes" was intended to be a substantially
         verbatim recitation of a provision of the Indenture, the Note
         Guarantees or the Notes.

                           Without the consent of each Holder affected, an
         amendment, supplement or waiver may not (with respect to any Notes held
         by a non-consenting Holder) (1) reduce the percentage of principal
         amount of Notes whose Holders must consent to an amendment, supplement
         or waiver; (2) reduce, or change the Stated Maturity of, the principal

         payment of interest on any Note; (4) waive a Default or Event of
         Default in the payment of principal of, or premium, if any, interest or
         Additional Interest, if any, on the Notes (except a


                                      A1-5

         rescission of acceleration of the Notes by the Holders of at least a
         majority in aggregate principal amount of the Notes and a waiver of the
         payment default that resulted from such acceleration); (5) make any
         Note payable in money other than that stated in the Notes; (6) make any
         change in the provisions of the Indenture relating to waivers of past
         Defaults or Events of Default or the rights of Holders to receive
         payments of principal of, or premium, if any, interest or Additional
         Interest, if any, on the Notes; (7) waive a redemption payment with

                  (12) DEFAULTS AND REMEDIES. Events of Default include: (i)
         default for 30 days in the payment when due of interest or Additional
         Interest on the Notes; (ii) default in payment of principal of or
         premium, if any, on the Notes when the same becomes due and payable at
         maturity, upon redemption or otherwise, (iii) failure by the Company or
         any of its Restricted Subsidiaries to comply with Sections 3.09, 4.10,
         4.14 or 5.01 of the Indenture; (iv) failure by the Company or any
         Guarantor for 60 days after notice to comply with any other covenant or

         other agreements relating to Indebtedness of the Company for money
         borrowed in excess of $20.0 million which default (a) results in the
         acceleration of such Indebtedness prior to its express maturity, or (b)
         is caused by a failure to pay principal of, or interest or premium, if
         any, on such Indebtedness prior to the expiration of the grace period
         provided in such Indebtedness on the date of such default; (vi) certain
         final judgments for the payment of money in excess of $20.0 million
         that remain undischarged for a period of 60 days; (vii) certain events
         of bankruptcy or insolvency with respect to the Company or any
         Restricted Subsidiary that is a Significant Subsidiary or any group of
         Restricted Subsidiaries that, taken as a whole, would constitute a
         Significant Subsidiary and (viii) except as permitted by the Indenture,
         any Note Guarantee shall be held in any judicial proceeding to be
         unenforceable or invalid or shall cease for any reason to be in full
         force and effect or any Guarantor or any Person acting on its behalf
         shall deny or disaffirm its obligations under such Guarantor's Note
         Guarantee. If any Event of Default occurs and is continuing, the
         Trustee or the Holders of at least 25% in principal amount of the then
         outstanding Notes may declare all the Notes to be due and payable.
         Notwithstanding the foregoing, in the case of an Event of Default
         arising from certain events of bankruptcy or insolvency, all
         outstanding Notes will become due and payable without further action or
         notice. Holders may not enforce the Indenture or the Notes except as
         provided in the Indenture. Subject to certain limitations, Holders of a
         majority in principal amount of the then outstanding Notes may direct
         the Trustee in its exercise of any trust or power. The Trustee may
         withhold from Holders of the Notes notice of any continuing Default or
         Event of Default (except a Default or Event of Default relating to the
         payment of principal, premium, interest or Additional Interest) if it
         determines that withholding notice is in their interest. The Holders of
         a majority in aggregate principal amount of the Notes then outstanding
         by notice to the Trustee may on behalf of the Holders of all of the
         Notes waive any existing Default or Event of Default and its
         consequences under the Indenture except a continuing Default or Event
         of Default in the payment of principal of, or premium, if any, interest
         or Additional Interest, if any, on the Notes. The Company is required
         to deliver to the Trustee annually a statement regarding compliance
         with the Indenture, and the Company is required upon becoming aware of
         any Default or Event of Default, to deliver to the Trustee a statement
         specifying such Default or Event of Default.

                  (13) DISCHARGE PRIOR TO MATURITY. The Indenture with respect
         to the Notes shall be discharged and canceled upon the payment of all
         of the Notes and, subject to Article 8 of the Indenture, shall be
         discharged except for certain obligations upon the irrevocable deposit
         with the


                                      A1-6

         Trustee of any combination of funds and non-callable Government
         Obligations sufficient for such payment.

                  (14) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its
         individual or any other capacity, may make loans to, accept deposits
         from, and perform services for the Company, any Guarantor or any of
         their respective Affiliates, and may otherwise deal with the Company,
         any Guarantor or any such Affiliate, as if it were not the Trustee.

                  (15) NO RECOURSE AGAINST OTHERS. No past, present or future
         director, officer, employee, incorporator or stockholder of the Company
         or any of the Guarantors, as such, will have any liability for any
         obligations of the Company or such Guarantor under the Notes, the Note
         Guarantees or the Indenture or for any claim based on, in respect of,
         or by reason of, such obligations or their creation. Each Holder by
         accepting a Note waives and releases all such liability. The waiver and
         release are part of the consideration for the issuance of the Notes.

                  (16) AUTHENTICATION. This Note will not be valid until
         authenticated by the manual signature of the Trustee or an
         authenticating agent.

                  (17) ABBREVIATIONS. Customary abbreviations may be used in the
         name of a Holder or an assignee, such as: TEN COM (= tenants in

         numbers either as printed on the Notes or as contained in any notice of
         redemption and reliance may be placed only on the other identification
         numbers placed thereon.

         This Note is one of a duly authorized issue of 8-3/4% Senior Notes due

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

                  (1) INTEREST. The Company promises to pay interest on the
         principal amount of this Note at 8-3/4% per annum from July 31, 2003
         until maturity and shall pay the Additional Interest, if any, payable
         pursuant to Section 6 of the Registration Rights Agreement referred to
         below. The Company will pay interest and Additional Interest, if any,
         semi-annually in arrears on January 15 and July 15 of each year, or if
         any such day is not a Business Day, on the next succeeding Business Day
         (each, an "Interest Payment Date"). Interest on the Notes will accrue
         from the most recent date to which interest has been paid or, if no
         interest has been paid, from July 31, 2003; provided that if there is
         no existing Default in the payment of interest, and if this Note is
         authenticated between a record date referred to on the face hereof and
         the next succeeding Interest Payment Date, interest shall accrue from
         such next succeeding Interest Payment Date; provided, further, that the
         first Interest Payment Date shall be January 15, 2004. The Company will
         pay interest (including post-petition interest in any proceeding under
         any Bankruptcy Law) on overdue principal and premium, if any, from time
         to time at a rate that is 1% per annum in excess of the interest rate
         then in effect to the extent lawful; it will pay interest (including
         post-petition interest in any proceeding under any Bankruptcy Law) on
         overdue installments of interest and Additional Interest, if any
         (without regard to any applicable grace periods) from time to time at
         the same rate to the extent lawful. Interest will be computed on the
         basis of a 360-day year of twelve 30-day months.


                                      A2-3

         Until this Regulation S Temporary Global Note is exchanged for one or
more Regulation S Permanent Global Notes, the Holder hereof shall not be
entitled to receive payments of interest hereon; until so exchanged in full,
this Regulation S Temporary Global Note shall in all other respects be entitled
to the same benefits as other Notes under the Indenture.

                  (2) METHOD OF PAYMENT. The Company will pay interest on the
         Notes (except defaulted interest) and Additional Interest, if any, to
         the Persons who are registered Holders of Notes at the close of
         business on the January 1 or July 1 next preceding the Interest Payment
         Date, even if such Notes are canceled after such record date and on or
         before such Interest Payment Date, except as provided in Section 2.12
         of the Indenture with respect to defaulted interest. The Notes will be
         payable as to principal and premium, if any, interest and Additional
         Interest, if any, at the office or agency of the Company maintained for
         such purpose within the City and State of New York, or, at the option
         of the Company, payment of interest and Additional Interest, if any,
         may be made by check mailed to the Holders at their addresses set forth
         in the register of Holders maintained by the Registrar; provided that
         payment by wire transfer of immediately available funds will be
         required with respect to principal of, and premium, if any, interest
         and Additional Interest, if any, on all Global Notes and any other
         Notes with any aggregate principal amount in excess of $1,000,000 the
         Holder of which has provided wire transfer instructions to the Company
         or the Paying Agent. Such payment will be in such coin or currency of
         the United States of America as at the time of payment is legal tender
         for payment of public and private debts.

                  (3) PAYING AGENT AND REGISTRAR. Initially, JPMorgan Chase
         Bank, the Trustee under the Indenture, will act as Paying Agent and
         Registrar. The Company may change any Paying Agent or Registrar without
         notice to any Holder. The Company or any of its Domestic Subsidiaries
         may act in any such capacity.

                  (4) INDENTURE. The Company issued the Notes under an Indenture
         dated as of July 31, 2003 (the "Indenture") among the Company, the
         Guarantors and the Trustee. The terms of the Notes include those stated
         in the Indenture and those made part of the Indenture by reference to
         the Trust Indenture Act of 1939, as amended (the "TIA"). The Notes are
         subject to all such terms, and Holders are referred to the Indenture
         and the TIA for a statement of such terms. To the extent any provision
         of this Note conflicts with the express provisions of the Indenture,
         the provisions of the Indenture shall govern and be controlling. The
         Notes are general unsecured obligations of the Company and are
         initially issued in an aggregate principal amount of $380,000,000. The
         Company may, subject to the covenants set forth in the Indenture, issue
         Additional Notes from time to time without the consent of the Holders.
         The Notes initially issued and any Additional Notes subsequently issued
         under the Indenture will be treated as a single class for all purposes
         of the Indenture, including, without limitation, with respect to
         waivers, amendments, supplements, redemptions and offers to purchase.

                  (5) OPTIONAL REDEMPTION.

                           (a) Except as set forth in subparagraphs (b) and (c)

         will have the option to redeem the Notes, in whole or in part, upon not
         less than 30 nor more than 60 days' notice, at the redemption prices
         (expressed as percentages of principal amount) set forth below plus
         accrued and unpaid interest and Additional Interest, if any, on the

         the twelve-month period beginning on July 15 of the years indicated
         below, subject to the rights of Holders on the relevant record date to

        2009................................................   101.458%
        2010 and thereafter.................................   100.000%


                           (b) Notwithstanding the provisions of subparagraph
         (a) of this Paragraph 5, at any time on or prior to July 15, 2007, the
         Company may on any one or more occasions redeem up to 35% of the
         aggregate principal amount of Notes issued under the Indenture with the
         net cash proceeds of one or more Public Equity Offerings at a
         redemption price equal to 108.75% of the aggregate principal amount
         plus accrued and unpaid interest and Additional Interest, if any, to
         the redemption date thereof; provided that at least 65% in aggregate
         principal amount of the Notes issued under the Indenture remains
         outstanding immediately after the occurrence of such redemption and
         that such redemption occurs within 60 days of the date of the closing
         of such Public Equity Offering.

         price equal to 100% of the principal amount of Notes redeemed plus the
         Applicable Premium as of, and accrued and unpaid interest and
         Additional Interest, if any, to the redemption date, subject to the
         rights of Holders on the relevant record date to receive interest due
         on the relevant Interest Payment Date. "Applicable Premium" means, with
         respect to any Note on any redemption date, the greater of (1) 1.0% of
         the principal amount of the Note or (2) the excess, if any, of (a) the
         present value on such redemption date of (i) the redemption price of
         the note at July 15, 2007 (such redemption price being set forth in
         paragraph 5(a)) plus (ii) all required interest payments due on the
         Note through July 15, 2007 (excluding accrued but unpaid interest to
         the redemption date), computed using a discount rate equal to the
         Treasury Rate as of such redemption date plus 50 basis points, over (b)
         the principal amount of the Note. "Treasury Rate" means, as of any
         redemption date, the yield to maturity as of such redemption date of
         United States Treasury securities with a constant maturity (as compiled
         and published in the most recent Federal Reserve Statistical Release
         H.15 (519) that has become publicly available at least two Business
         Days prior to the redemption date (or, if such Statistical Release is
         no longer published, any publicly available source of similar market
         data)) most nearly equal to the period from the redemption date to July
         15, 2007; provided, however, that if the period from the redemption
         date to July 15, 2007, is less than one year, the weekly average yield
         on actually traded United States Treasury securities adjusted to a
         constant maturity of one year shall be used.

                  (6) MANDATORY REDEMPTION.

         The Company will not be required to make mandatory redemption or
sinking fund payments with respect to the Notes.

                  (7) REPURCHASE AT OPTION OF HOLDER.

                           (a) If there is a Change of Control, the Company will
         be required to make an offer (a "Change of Control Offer") to each
         Holder to repurchase all or any part (equal to $1,000 or an integral
         multiple thereof) of such Holder's Notes at a purchase price equal to
         101% of the aggregate principal amount thereof plus accrued and unpaid
         interest and Additional Interest, if any on the Notes repurchased, if
         any, to the Change of Control Payment Date, subject to the rights of
         Holders on the relevant record date to receive interest due on the
         relevant Interest


                                      A2-5

         Payment Date (the "Change of Control Payment"). Within 30 days
         following any Change of Control, the Company will mail a notice to each
         Holder setting forth the procedures governing the Change of Control
         Offer as required by the Indenture.

                           (b) If the Company or a Restricted Subsidiary
         consummates any Asset Sales, within ten days of each date on which the
         aggregate amount of Excess Proceeds exceeds $15.0 million, the Company
         will commence an offer to all Holders of Notes and all holders of other
         Pari Passu Indebtedness containing provisions similar to those set
         forth in the Indenture with respect to offers to purchase or redeem
         with the proceeds of sales of assets (an "Asset Sale Offer") to
         purchase the maximum principal amount of Notes and such other Pari
         Passu Indebtedness that may be purchased out of the Excess Proceeds at
         an offer price in cash in an amount equal to 100% of the principal
         amount thereof plus accrued and unpaid interest and Additional Interest
         thereon, if any, to the date of purchase, in accordance with the
         procedures set forth in the Indenture. If any Excess Proceeds remain
         after consummation of an Asset Sale Offer, the Company may use such
         Excess Proceeds for any purpose not otherwise prohibited by the
         Indenture. If the aggregate principal amount of Notes and other Pari
         Passu Indebtedness tendered into such Asset Sale Offer exceeds the
         amount of Excess Proceeds, the Trustee shall select the Notes and such
         other Pari Passu Indebtedness to be purchased on a pro rata basis based
         on the principal amount of Notes and such other Pari Passu Indebtedness
         tendered. Holders of Notes that are the subject of an offer to purchase
         will receive an Asset Sale Offer from the Company prior to any related
         purchase date and may elect to have such Notes purchased by completing
         the form entitled "Option of Holder to Elect Purchase" on the reverse
         of this Note and otherwise complying with the procedures set forth in
         the Indenture. Upon completion of each Asset Sale Offer, the amount of
         Excess Proceeds shall be reset at zero.

                  (8) NOTICE OF REDEMPTION. Notice of redemption will be mailed
         at least 30 days but not more than 60 days before the redemption date
         to each Holder whose Notes are to be redeemed at its registered
         address. Notes in denominations larger than $1,000 may be redeemed in
         part but only in whole multiples of $1,000, unless all of the Notes
         held by a Holder are to be redeemed. On and after the redemption date
         interest ceases to accrue on Notes or portions thereof called for
         redemption.

                  (9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in
         registered form without coupons in denominations of $1,000 and integral
         multiples of $1,000. The transfer of Notes may be registered and Notes
         may be exchanged as provided in the Indenture. The Registrar and the
         Trustee may require a Holder, among other things, to furnish
         appropriate endorsements and transfer documents and the Company may
         require a Holder to pay any taxes and other governmental charges
         required by law or permitted by the Indenture. The Company need not
         exchange or register the transfer of any Note or portion of a Note
         selected for redemption, except for the unredeemed portion of any Note
         being redeemed in part. Also, the Company need not exchange or register
         the transfer of any Note for a period of 15 days before a selection of
         Notes to be redeemed.

                  This Regulation S Temporary Global Note is exchangeable in
         whole or in part for one or more Global Notes only (i) on or after the
         termination of the 40-day restricted period (as defined in Regulation
         S) and (ii) upon presentation of certificates (accompanied by an
         Opinion of Counsel, if applicable) required by Article 2 of the
         Indenture. Upon exchange of this Regulation S Temporary Global Note for
         one or more Global Notes, the Trustee shall cancel this Regulation S
         Temporary Global Note.

                  (10) PERSONS DEEMED OWNERS. The registered Holder of a Note
         may be treated as its owner for all purposes.

                  (11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
         exceptions and limitations, the Indenture, the Note Guarantees or the
         Notes may be amended or supplemented with the consent of the Holders of
         at least a majority in principal amount of the then outstanding Notes,
         voting as a single class, and any existing default or compliance with
         any provision of the Indenture, the Note Guarantees or the Notes may be

         certificated Notes, to provide for the assumption of the Company's or a
         Guarantor's obligations to Holders of the Notes in case of a merger or
         consolidation or a transfer of all or substantially all of its assets,

         to the Holders of the Notes or that does not adversely affect in any
         material respect the legal rights under the Indenture of any such
         Holder, to provide any security for, any guarantees of or any
         additional obligors on the Notes or the Note Guarantees, or to confirm
         and evidence the release, termination or discharge of any such security
         or guarantee when such release, termination or discharge is permitted

         to effect or maintain the qualification of the Indenture under the TIA,
         and to conform the text of the Indenture or the Notes to any provision
         in the Offering Circular relating to the initial issuance of the Notes
         in the section "Description of Notes" to the extent that such provision
         in the "Description of Notes" was intended to be a substantially
         verbatim recitation of a provision of the Indenture, the Note
         Guarantees or the Notes.

                  Without the consent of each Holder affected, an amendment,
         supplement or waiver may not (with respect to any Notes held by a
         non-consenting Holder) (1) reduce the percentage of principal amount of
         Notes whose Holders must consent to an amendment, supplement or waiver;
         (2) reduce, or change the Stated Maturity of, the principal of any
         Note, change the date on which any of the Notes may be subject to
         redemption or repurchase or reduce the redemption or repurchase price
         of the Notes; (3) reduce the rate of or change the time for payment of
         interest on any Note; (4) waive a Default or Event of Default in the
         payment of principal of, or premium, if any, interest or Additional
         Interest, if any, on the Notes (except a rescission of acceleration of
         the Notes by the Holders of at least a majority in aggregate principal
         amount of the Notes and a waiver of the payment default that resulted
         from such acceleration); (5) make any Note payable in money other than
         that stated in the Notes; (6) make any change in the provisions of the
         Indenture relating to waivers of past Defaults or Events of Default or
         the rights of Holders to receive payments of principal of, or premium,
         if any, interest or Additional Interest, if any, on the Notes; (7)

         its Note Guarantee or the Indenture, except in accordance with the

                  (12) DEFAULTS AND REMEDIES. Events of Default include: (i)
         default for 30 days in the payment when due of interest or Additional
         Interest on the Notes; (ii) default in payment of principal of or
         premium, if any, on the Notes when the same becomes due and payable at
         maturity, upon redemption or otherwise, (iii) failure by the Company or
         any of its Restricted Subsidiaries to comply with Sections 3.09, 4.10,
         4.14 or 5.01 of the Indenture; (iv) failure by the Company or any
         Guarantor for 60 days after notice to comply with any other covenant or
         agreement in the Indenture, or the Notes; (v) default under certain
         other agreements relating to


                                      A2-7

         Indebtedness of the Company for money borrowed in excess of $20.0
         million which default (a) results in the acceleration of such
         Indebtedness prior to its express maturity, or (b) is caused by a
         failure to pay principal of, or interest or premium, if any, on such
         Indebtedness prior to the expiration of the grace period provided in
         such Indebtedness on the date of such default; (vi) certain final
         judgments for the payment of money in excess of $20.0 million that
         remain undischarged for a period of 60 days; (vii) certain events of
         bankruptcy or insolvency with respect to the Company or any Restricted
         Subsidiary that is a Significant Subsidiary or any group of Restricted
         Subsidiaries that, taken as a whole, would constitute a Significant
         Subsidiary and (viii) except as permitted by the Indenture, any Note
         Guarantee shall be held in any judicial proceeding to be unenforceable
         or invalid or shall cease for any reason to be in full force and effect
         or any Guarantor or any Person acting on its behalf shall deny or
         disaffirm its obligations under such Guarantor's Note Guarantee. If any
         Event of Default occurs and is continuing, the Trustee or the Holders
         of at least 25% in principal amount of the then outstanding Notes may
         declare all the Notes to be due and payable. Notwithstanding the
         foregoing, in the case of an Event of Default arising from certain
         events of bankruptcy or insolvency, all outstanding Notes will become
         due and payable without further action or notice. Holders may not
         enforce the Indenture or the Notes except as provided in the Indenture.
         Subject to certain limitations, Holders of a majority in principal
         amount of the then outstanding Notes may direct the Trustee in its
         exercise of any trust or power. The Trustee may withhold from Holders
         of the Notes notice of any continuing Default or Event of Default
         (except a Default or Event of Default relating to the payment of
         principal, premium, interest or Additional Interest) if it determines
         that withholding notice is in their interest. The Holders of a majority
         in aggregate principal amount of the Notes then outstanding by notice
         to the Trustee may on behalf of the Holders of all of the Notes waive
         any existing Default or Event of Default and its consequences under the
         Indenture except a continuing Default or Event of Default in the
         payment of principal of, or premium, if any, interest or Additional
         Interest, if any, on the Notes. The Company is required to deliver to
         the Trustee annually a statement regarding compliance with the
         Indenture, and the Company is required upon becoming aware of any
         Default or Event of Default, to deliver to the Trustee a statement
         specifying such Default or Event of Default.

                  (13) DISCHARGE PRIOR TO MATURITY. The Indenture with respect
         to the Notes shall be discharged and canceled upon the payment of all
         of the Notes and, subject to Article 8 of the Indenture, shall be
         discharged except for certain obligations upon the irrevocable deposit
         with the Trustee of any combination of funds and non-callable
         Government Obligations sufficient for such payment.

                  (14) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its
         individual or any other capacity, may make loans to, accept deposits
         from, and perform services for the Company, any Guarantor or any of
         their respective Affiliates, and may otherwise deal with the Company,
         any Guarantor or any such Affiliate, as if it were not the Trustee.

                  (15) NO RECOURSE AGAINST OTHERS. No past, present or future
         director, officer, employee, incorporator or stockholder of the Company
         or any of the Guarantors, as such, will have any liability for any
         obligations of the Company or such Guarantor under the Notes, the Note
         Guarantees or the Indenture or for any claim based on, in respect of,
         or by reason of, such obligations or their creation. Each Holder by
         accepting a Note waives and releases all such liability. The waiver and
         release are part of the consideration for the issuance of the Notes.

                  (16) AUTHENTICATION. This Note will not be valid until
         authenticated by the manual signature of the Trustee or an
         authenticating agent.

         Company has caused CUSIP numbers to be printed on the Notes and the
         Trustee may use CUSIP numbers in notices of redemption as a convenience
         to Holders. No representation is made as to the accuracy of such
         numbers either as printed on the Notes or as contained in any notice of
         redemption and reliance may be placed only on the other identification
         numbers placed thereon.

                  (19) ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES

         Additional Notes to register such Additional Notes under the Securities
         Act (collectively, the "Registration Rights Agreement").

                  (20) TRANSFER RESTRICTIONS. By its acceptance of any Note
         bearing a legend restricting transfer, each Holder of such Note
         acknowledges the restrictions on transfer of such Note set forth in the
         Indenture and in such legend and agrees that it will transfer such Note
         only as provided in the Indenture.

                               W I T N E S S E T H

         WHEREAS, the Company and the Guarantors have heretofore executed and
delivered to the Trustee an indenture (the "Indenture"), dated as of July 31,
2003, [add appropriate references to any further supplements] providing for the
issuance of 8-3/4% Senior Notes due 2011 (the "Notes");

         WHEREAS, Section 4.17 of the Indenture provides that under certain
circumstances the Guaranteeing Subsidiary shall execute and deliver to the
Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary
shall unconditionally guarantee all of the Company's payment obligations under
the Notes and the Indenture on the terms and conditions set forth herein (the
"Note Guarantee"); and

         WHEREAS, Section 9.01(5) of the Indenture provides that, without the
consent of any Holder (as defined therein), the Company, the Guarantors and the
Trustee may amend or supplement the Indenture to add guarantees of or additional
obligors on the Notes or the Note Guarantees;

         WHEREAS, the Company and the Guarantors, pursuant to the foregoing
authority, propose to amend and supplement the Indenture in certain respects to
provide for the Note Guarantee of the Guaranteeing Subsidiary;

         NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the
Company, the Guaranteeing Subsidiary, the other Guarantors and the Trustee
mutually covenant and agree for the equal and ratable benefit of the Holders of
the Notes as follows:

         1. CAPITALIZED TERMS. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Indenture.

         2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees as
follows:

                           (a) Along with all Guarantors named in the Indenture,
                  to jointly and severally unconditionally guarantee to each
                  Holder of a Note authenticated and delivered by the Trustee
                  and to the Trustee and its successors and assigns,
                  irrespective of the validity and enforceability of the
                  Indenture, the Notes or the obligations of the Company
                  thereunder, that:

                           (i) the principal of, and premium, if any, interest
                 and Additional Interest, if any, on the Notes will be promptly
                 paid in full when due, whether at maturity, by acceleration,
                 redemption or otherwise, and interest on the overdue principal
                 of and interest on the Notes, if any, if lawful, and all other
                 payment obligations of the Company to the


                                      F-1

                  Holders or the Trustee thereunder will be promptly paid in
                  full or performed, all in accordance with the terms hereof and
                  thereof; and

                           (ii) in case of any extension of time of payment or
                 renewal of any Notes or any of such other payment obligations,
                 that same will be promptly paid in full when due or performed
                 in accordance with the terms of the extension or renewal,
                 whether at stated maturity, by acceleration or otherwise.

                           Failing payment when due of any amount so guaranteed
                 or any performance so guaranteed for whatever reason, the
                 Guarantors and the Guaranteeing Subsidiary shall be jointly and
                 severally obligated to pay the same immediately. The
                 Guaranteeing Subsidiary agrees that this is a guarantee of
                 payment and not of collection.

                           (b) The Guaranteeing Subsidiary hereby agrees that
                  its obligations hereunder shall be, to the extent permitted by
                  law, unconditional, irrespective of the validity, regularity
                  or enforceability of the Notes or the Indenture, the absence
                  of any action to enforce the same, any waiver or consent by
                  any Holder with respect to any provisions hereof or thereof,
                  the recovery of any judgment against the Company, any action
                  to enforce the same or any other circumstance which might
                  otherwise constitute a legal or equitable discharge or defense
                  of a guarantor. To the extent permitted by law, the
                  Guaranteeing Subsidiary hereby waives diligence, presentment,
                  demand of payment, filing of claims with a court in the event
                  of insolvency or bankruptcy of the Company, any right to
                  require a proceeding first against the Company, protest,
                  notice and all demands whatsoever and, subject to Article 8 of
                  the Indenture, covenants that this Note Guarantee will not be
                  discharged except by complete performance of the obligations
                  contained in the Notes and the Indenture. The Guaranteeing
                  Subsidiary accepts all obligations of a Guarantor under the
                  Indenture.

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

                           (d) The Guaranteeing Subsidiary agrees that it will
                  not be entitled to any right of subrogation in relation to the
                  Holders in respect of any obligations guaranteed hereby until
                  payment in full of all obligations guaranteed hereby. The
                  Guaranteeing Subsidiary further agrees that, as between the
                  Guarantors, on the one hand, and the Holders and the Trustee,
                  on the other hand, (1) the maturity of the obligations
                  guaranteed hereby may be accelerated as provided in Article 6
                  of the Indenture for the purposes of this Note Guarantee,
                  notwithstanding any stay, injunction or other prohibition
                  preventing such acceleration in respect of the obligations
                  guaranteed hereby, and (2) in the event of any declaration of
                  acceleration of such obligations as provided in Article 6 of
                  the Indenture, such obligations (whether or not due and
                  payable) will forthwith become due and payable by the
                  Guarantors for the purpose of this Note Guarantee. The
                  Guarantors will have the right to seek contribution from any
                  non-paying Guarantor so long as the exercise of such right
                  does not impair the rights of the Holders under the Note
                  Guarantee.

                                    (e) In the event of a default in the payment
                  of principal of, or premium, if any, interest or Additional
                  Interest, if any, on any Note when and as the same shall
                  become due, whether at maturity, by acceleration, redemption
                  or otherwise, or in the


                                      F-2

                  event of a default in the payment of any interest on the
                  overdue principal of or interest on such Note, if any, if
                  lawful, or any other payment obligation of the Company to the
                  Holder of such Note or the Trustee thereunder, each of the
                  Trustee and such Holder shall have the right to proceed first
                  and directly against the Guaranteeing Subsidiary under the
                  Indenture without first proceeding against the Company or
                  exhausting any other remedies which the Trustee or such Holder
                  may have and without resorting to any other security held by
                  it.

                                    (f) The Trustee shall have the right, power
                  and authority to do all things it deems necessary or advisable
                  to enforce the provisions of the Indenture relating to the
                  Note Guarantee and to protect the interests of the Holders of
                  the Notes and, in the event of a default in the payment of
                  principal of, or premium, if any, interest or Additional
                  Interest, if any, on any Note when and as the same shall
                  become due, whether at maturity, by acceleration, redemption
                  or otherwise, or in the event of a default in the payment of
                  any interest on the overdue principal of or interest on such
                  Note, if any, if lawful, or any other payment obligation of
                  the Company to the Holder of such Note or the Trustee
                  thereunder, the Trustee may institute or appear in such
                  appropriate judicial proceedings as the Trustee shall deem
                  most effectual to protect and enforce any of its rights and
                  the rights of the Holders, whether for the specific
                  enforcement of any covenant or agreement in the Indenture
                  relating to the Note Guarantee or in aid of the exercise of
                  any power granted herein, or to enforce any other proper
                  remedy. Without limiting the generality of the foregoing, in
                  the event of a default in the payment of principal of, or
                  premium, if any, interest or Additional Interest, if any, on
                  any Note when due, the Trustee may institute a judicial
                  proceeding for the collection of the sums so due and unpaid,
                  and may prosecute such proceeding to judgment or final decree,
                  and may enforce the same against the Guaranteeing Subsidiary
                  and collect the moneys adjudged or decreed to be payable in
                  the manner provided by law out of the property of the
                  Guaranteeing Subsidiary, wherever situated.

                           (i) Pursuant to Section 10.02 of the Indenture, the
                  Obligations of the Guaranteeing Subsidiary will be limited to
                  the maximum amount that will, after giving effect to such
                  maximum amount and all other contingent and fixed liabilities
                  of the Guaranteeing Subsidiary, that are relevant under any
                  applicable Bankruptcy Law, the Uniform Fraudulent Conveyance
                  Act, the Uniform Fraudulent Transfer Act or any similar
                  federal or state law relating to fraudulent transfers or
                  conveyance, and after giving effect to any collections from,
                  rights to receive contribution from or payments made by or on
                  behalf of any other Guarantor in respect of the obligations of
                  such other Guarantor under Article 10 of the Indenture, result
                  in the obligations of such Guarantor under this Note Guarantee
                  not constituting a fraudulent transfer or conveyance.

         3. EXECUTION AND DELIVERY. The Guaranteeing Subsidiary agrees that the
Note Guarantee shall remain in full force and effect notwithstanding any failure
to endorse on each Note a notation of such Note Guarantee.

         4. GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.

                           (a) Except as otherwise provided in Section 5 hereof,
                  the Guaranteeing Subsidiary may not sell or otherwise dispose
                  of all or substantially all of its assets to, or consolidate
                  with or merge with or into (whether or not such Guarantor is
                  the surviving Person) another Person, other than the Company
                  or another Guarantor, unless:

                                      F-3

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

                           (ii) either (A) the Person acquiring the property in
                 any such sale or disposition or the Person formed by or
                 surviving any such consolidation or merger (in each case if
                 other than the Guaranteeing Subsidiary) assumes all the
                 obligations of that Guarantor under the Indenture, this
                 Supplemental Indenture and its Note Guarantee pursuant to a
                 supplemental indenture satisfactory to the Trustee, and under
                 the Registration Rights Agreement, or (B) if applicable, the
                 Net Proceeds of such sale or other disposition are applied in
                 accordance with the applicable provisions of the Indenture,
                 including without limitation, Section 4.10 thereof.

                           (b) Upon any consolidation or merger, or any sale or
                  other disposition of all or substantially all of the assets
                  of, the Guaranteeing Subsidiary in a transaction that is
                  subject to, and that complies with the provisions of, Section
                  4(a) hereof, the successor Person formed by such consolidation
                  or into or with which such Guarantor is merged or to which
                  such sale or other disposition is made shall succeed to, and
                  be substituted for (so that from and after the date of such
                  consolidation, merger, sale, lease, conveyance or other
                  disposition, the provisions of the Indenture referring to the
                  applicable "Guarantor" shall refer instead to the successor
                  Person and not to such Guarantor), and may exercise every
                  right and power of such Guarantor under the Indenture, this
                  Supplemental Indenture and its Note Guarantee with the same
                  effect as if such successor Person had been named as a
                  Guarantor herein and therein and the predecessor Guarantor
                  shall be released from all obligations under the Indenture,
                  this Supplemental Indenture and its Note Guarantee. Such
                  successor Person thereupon may cause to be signed any or all
                  of the Note Guarantees to be endorsed upon all of the Notes
                  issuable under the Indenture which theretofore shall not have
                  been signed by the Company and delivered to the Trustee. All
                  the Note Guarantees so issued will in all respects have the
                  same legal rank and benefit under the Indenture as the Note
                  Guarantees theretofore and thereafter issued in accordance
                  with the terms of the Indenture as though all of such Note
                  Guarantees had been issued at the date of the execution of the
                  Indenture

                           (c) Except as set forth in Articles 4 and 5 and
                  Section 10.04 of the Indenture, and notwithstanding clauses
                  (a)(ii) and (b) above, nothing contained in the Indenture or
                  in any of the Notes shall prevent any consolidation or merger
                  of the Guaranteeing Subsidiary with or into the Company or
                  another Guarantor, or shall prevent any sale or other
                  disposition of all or substantially all of the assets of the
                  Guaranteeing Subsidiary to the Company or another Guarantor.

         5.       RELEASES.

                           (a) In the event of any sale or other disposition of
                  all or substantially all of the assets of the Guaranteeing
                  Subsidiary, by way of merger, consolidation or otherwise, or a
                  sale or other disposition of all of the Capital Stock of the
                  Guaranteeing Subsidiary, in each case to a Person that is not
                  (either before or after giving effect to such transactions)
                  the Company or a Restricted Subsidiary of the Company, then
                  such Guarantor (in the event of a sale or other disposition,
                  by way of merger, consolidation or otherwise, of all of the
                  Capital Stock of such Guarantor) or the Person acquiring the
                  property (in the event of a sale or other disposition of all
                  or substantially all of the assets of such Guarantor) will be
                  released and relieved of any obligations under its Note
                  Guarantee; provided that the Net Proceeds of such sale or
                  other disposition are applied in accordance with the


                                      F-4

                  applicable provisions of the Indenture, including without
                  limitation Section 4.10 of the Indenture. Upon delivery by the
                  Company to the Trustee of an Officers' Certificate and an
                  Opinion of Counsel to the effect that such sale or other
                  disposition was made by the Company in accordance with the
                  provisions of the Indenture, including without limitation
                  Section 4.10 of the Indenture, the Trustee shall execute any
                  documents reasonably required in order to evidence the release
                  of the Guaranteeing Subsidiary from its obligations under its
                  Note Guarantee.

                           (b) If the Guaranteeing Subsidiary is not released
                  from its obligations under its Note Guarantee, it shall remain
                  liable for the full amount of principal of and interest on the
                  Notes and for the other obligations of any Guarantor under the
                  Indenture to the extent provided in Article 10 of the
                  Indenture.

         6. No Recourse Against Others. No past, present or future director,
officer, employee, incorporator, or stockholder of the Guaranteeing Subsidiary,
as such, shall have any liability for any obligations of the Company or the
Guaranteeing Subsidiary under the Notes, any Note Guarantees, the Indenture or
this Supplemental Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of the Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes. Such waiver may not be
effective to waive liabilities under the federal securities laws.

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

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

         9. Effect of Headings. The Section headings herein are for convenience
only and shall not affect the construction hereof.

         10. The Trustee. The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which
recitals are made solely by the Guaranteeing Subsidiary, the other Guarantors
and the Company.

         11. Trust Indenture Act Controls. If any provision of this Supplemental
Indenture limits, qualifies or conflicts with the duties imposed by TIA Section
318(c), the imposed duties will control.

         12. Supplemental Indenture Incorporated into Indenture. The terms and
conditions of this Supplemental Indenture shall be deemed to be part of the
Indenture for all purposes with respect to the Notes and the Note Guarantees.
