state of Delaware, with full corporate power and authority to own, lease and
operate its properties and to conduct its business as currently conducted, and
is duly registered and qualified to conduct its business and is in good standing

         (b) Authorization; Enforcement. The Company has the requisite corporate
power and authority to enter into and perform this Agreement and to issue and
sell the Shares in accordance with the terms hereof. The execution, delivery and
performance of this Agreement by the Company and the consummation by it of the

necessary corporate action, and no further consent or authorization of the
Company or its board of directors or stockholders is required. This Agreement
has been duly executed and delivered by the Company. This Agreement constitutes
a valid and binding obligation of the Company enforceable against the Company in
accordance with its terms, except as such enforceability may be limited by

generally the enforcement of, creditor's rights and remedies or by other
equitable principles of general application.

Agreement, other than (i) the filings set forth in Section 3.1, (ii) applicable
blue sky filings, (iii) the consents listed in Schedule 2.1(i) hereto, and (iv)

individually or in the aggregate, a Material Adverse Effect.

         (j) Certain Fees. Except as set forth on Schedule 2.1(j) hereto,
neither the Company nor any of its Affiliates or Subsidiaries have incurred or

brokerage fees or commissions payable to any broker or finder retained by or on

with the defense of any action brought to collect any brokerage fees or
commissions by any such broker or finder.

Securities Act and the published rules and regulations of the Commission, and
neither of such documents will include any untrue statement of material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading. The offer and sale of the Shares,
and the offer of the Underlying Shares deemed to be made by virtue of the
Shares, are covered by the Registration Statement.

         Section 2.2 Representations and Warranties of the Purchaser. The
Purchaser hereby makes the following representations and warranties to the
Company:

         (a) Organization, Good Standing and Power. The Purchaser is a limited
liability company and has been duly organized and is validly existing and in
good standing under the laws of the state of Delaware, with full limited
liability company power and authority to own, lease and operate its properties
and to conduct its business as currently conducted, and is duly registered and
qualified to conduct its business and is in good standing in each jurisdiction
or place where the nature of its properties or the conduct of its business
requires such registration or qualification, except where the failure to
register or qualify would not have a Material Adverse Effect.

         (b) Authorization And Power; Enforcement. The Purchaser has the
requisite limited liability company power and authority to enter into, deliver
and perform this Agreement and to purchase the Shares in accordance with the
terms hereof. The execution, delivery and performance of this Agreement by the
Purchaser and consummation by it of the transactions hereby have been duly and
validly authorized by necessary limited liability company action, and no further
consent or authorization of the Purchaser or its manager, board of directors or
members is required. This Agreement has been duly executed and delivered by the
Purchaser. This Agreement constitutes, or shall constitute when executed and
delivered, a valid and binding obligation of the Purchaser enforceable against
the Purchaser in

                                       4
<PAGE>

accordance with its terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation,
conservatorship, receivership, or similar laws relating to, or affecting
generally the enforcement of, creditor's rights and remedies or by other
equitable principles of general application.

         (c) No Conflicts. The execution and delivery of this Agreement, the
acquisition of any of the Shares and the consummation of the transactions
contemplated by this Agreement by the Purchaser, will not (i) conflict with or
result in a breach of or a default under any of the terms or provisions of
Purchaser's organizational documents, or (ii) result in a violation of any
material provision of any law, statute, rule, regulation, or any existing
applicable decree, judgment or order by any court, federal or state regulatory
body, administrative agency, or other governmental body having jurisdiction over
the Purchaser.

         (d) Information. The Purchaser has received and carefully reviewed
copies of the Public Documents and has access to the Commission Documents. The
Purchaser understands that no federal, state, local or foreign governmental body
or regulatory authority has made any finding or determination relating to the
fairness of an investment in any of the Shares and that no federal, state, local
or foreign governmental body or regulatory authority has recommended or
endorsed, or will recommend or endorse, any investment in any of the Shares. The
Purchaser, in making the decision to purchase the Shares, has relied upon
independent investigation made by it and its advisors, if any, and has not
relied on any information or representations made by third parties or by the
Company or its officers, directors, employees, agents, accountants or attorneys.
The Purchaser and its advisors, if any, have been furnished with all materials
relating to the business, finances and operations of the Company and materials
relating to the offer and sale of the Shares which have been requested by the
Purchaser. The Purchaser and its advisors, if any, have been afforded the
opportunity to ask questions of the Company. The Purchaser has sought such
accounting, legal and tax advice as it has considered necessary to make an
informed investment decision with respect to its acquisition of the Shares. The
Purchaser understands that it (and not the Company) shall be responsible for its
own tax liabilities that may arise as a result of this investment or the
transactions contemplated by this Agreement.

         (e) Compliance with Laws. The Purchaser shall comply with all
applicable federal and state securities laws, rules and regulations in
connection with the sale of the Shares purchased by the Purchaser hereunder.

         (f) Certain Fees. Except as set forth on Schedule 2.2(f) hereto,
neither the Purchaser nor any of its Affiliates or Subsidiaries have incurred or
become liable for any brokerage commission or finder's fee relating to or in
connection with the transactions contemplated by this Agreement. The Purchaser
agrees to indemnify the Company against any claims against the Company for
brokerage fees or commissions payable to any broker or finder retained by or on
behalf of the Purchaser or any of its Affiliates or Subsidiaries in connection
with the defense of any action brought to collect any brokerage fees or
commissions by any such broker or finder.

         (g) Non-Public Information. Neither the Purchaser nor any of its
Affiliates, officers or agents will solicit any material non-public information
from the Company.

         (h) Investment Intent. The Purchaser is acquiring the Shares for its
own account and not with a view to, or for sale in connection with, any
distribution of the Shares or the Underlying Shares or any part thereof, nor
with the intention of distributing or reselling the same. The Purchaser has no
agreement or arrangement with the Company or with any third party for the sale
or disposition of the Shares or Underlying Shares to be purchased pursuant to
this Agreement.

                                       5

         (i) Trading Activities. The Purchaser covenants with the Company as
follows: The Purchaser's trading and distribution activities with respect to the
Shares and the Underlying Shares will be in compliance with all applicable state
and federal securities laws, rules and regulations (including, without
limitation, Regulation M promulgated under the Securities Act) and the rules and
regulations of the New York Stock Exchange. Neither the Purchaser nor any of its
affiliates (as that term is defined in Rule 405 promulgated under the Securities
Act) has taken, nor will any of them take, directly or indirectly, any action
designed to cause or that would result in, or which constitutes or that might
reasonably be expected to constitute, the stabilization or manipulation of the
price of the Common Stock to facilitate the purchase, sale or resale of the
Common Stock or the Shares.

         (j) Passive Investor. For the purposes of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, it is the intention of the
Purchaser to acquire the Shares and, upon conversion, redemption or the payment
of dividends thereon, the Underlying Shares, solely for the purpose of
investment (within the meaning of 16 C.F.R. Section 801.1(i)(1)), and the
Purchaser has no intention of participating in or influencing the formulation,
determination, or direction of the basic business decisions of the Company.
After the issuance of the Shares, the Purchaser will not Beneficially Own ten
percent (10%) or more of the Common Stock.

then traded) a supplemental listing application covering the Underlying Shares,
(B) provide to the Purchaser evidence of such filing, and (C) use its reasonable
best efforts to maintain the listing of its Common Stock thereon (or such other
exchange where the Common Stock is then listed). The Company shall, no less than
two Business Days prior to the filing of any disclosure required by clauses (ii)
and (iii) above, provide a copy thereof to the Purchaser for its review and
comment. The Company and the Purchaser shall consult with each other in issuing
any other press releases or otherwise making public statements or filings and
other communications with the Commission or any regulatory agency or stock
market or trading facility with respect to the transactions contemplated hereby,
and neither party shall issue any such press release or otherwise make any such
public statement, filings or other communications regarding such transactions

         (b) If the number of shares of Common Stock set forth in subparagraph

best efforts to register such additional shares of the Common Stock or register
the resale of such additional shares of Common Stock, as soon as necessary prior
to the issuance of such additional shares, to cover any such conversion,
redemption or dividend payment. The Company shall not have the right to elect to
redeem the Shares with shares of Common Stock pursuant to Section 7 of the
Certificate of Designations unless the Company has a sufficient number of shares
of Common Stock to cover such redemption either registered or registered for
resale under the Securities Act prior to such redemption.

         Section 3.2 Restrictions on Trading. The Purchaser hereby covenants and
agrees that from the Closing until the fifth (5th) day thereafter, neither the
Purchaser nor any of its agents, representatives, Affiliates, associates or any
other Person acting in concert with or under the control or direction of
Purchaser will, directly or indirectly, (i) purchase or cause to be purchased or
otherwise acquire or make any proposal to offer or agree to acquire, enter into

hypothecations or other dispositions or encumbrances involving the Securities
and/or (C) holding or maintaining any short and/or long positions in the
Securities.

         Section 3.3 Voting. From and after the Closing, each Holder and its
Affiliates shall be present, in person or by proxy, and without further action
hereby agree that they shall be deemed to be present, at all properly called
meetings of stockholders of the Company of which such Holder and its Affiliates
have notice so that all Voting Securities (including the Shares and the
Underlying Shares) Beneficially Owned by such Holder and its Affiliates shall be
counted for purposes of determining the presence of a quorum at such meetings.
Except as otherwise expressly permitted by this Agreement or the Certificate of
Designations, at all stockholder meetings after the Closing at which Voting
Securities Beneficially Owned by any Holder and its Affiliates are entitled to

Beneficially Owned by such Holder and its Affiliates in accordance with the
recommendation or direction of the board of directors of the Company, including,

without the prior written approval of the board of directors of the Company,

Beneficially Owns Shares and/or Underlying Shares (unless such Underlying Shares
were acquired in an Open Market Sale) and such Holder's Affiliates may at any
time collectively be the Beneficial Owner of more than ten percent (10%) in the
aggregate of the Company's Common Stock.

         Section 3.5 Transfer Restrictions. No Holder shall sell, assign,
transfer, pledge, hypothecate, encumber, grant any option with respect to or
otherwise dispose of any interest in (or enter into any agreement or
understanding with respect to the foregoing) ("TRANSFER"), directly or

Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent or cure breaches of the provisions of

entitled by law or equity.

         (b) Each of the Company and the Purchaser (i) hereby irrevocably
submits to the jurisdiction of the United States District Court and other courts
of the United States sitting in the State of Texas for the purposes of any suit,
action or proceeding arising out of or relating to this Agreement and (ii)
hereby waives, and agrees not to assert in any such suit, action or proceeding,
any claim that it is not personally subject to the jurisdiction of such court,
that the suit, action or proceeding is brought in an inconvenient forum or that
the venue of the suit, action or proceeding is improper. Each of the Company and
the Purchaser consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to such party at the address in effect for

requiring the observance by any Holder, only by a writing signed by the Company,

party of any breach hereof or default in the performance hereof shall not be
deemed to constitute a waiver of any other default or any succeeding breach or
default. No term or provision of this Agreement may be amended or supplemented
by any party hereto except pursuant to a writing executed by the Company and the
holders of a majority of the Convertible Preferred Stock then outstanding;
provided that no amendment shall be effected to impact a holder of Convertible
Preferred Stock in a disproportionately adverse fashion without the consent of

                                    THE NOTES

Section 2.01. Form and Dating.

                  (a)      General. The Notes and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A hereto. The Notes
may have notations, legends or endorsements required by law, stock exchange rule
or usage. Each Note shall be dated the date of its authentication. The Notes
shall be issued in registered, global form without interest coupons and only
shall be in minimum denominations of $1,000 and integral multiples of $1,000 in
excess thereof.

                  The terms and provisions contained in the Notes shall
constitute, and are hereby expressly made, a part of this Indenture and the
Company, the Guarantors and the Trustee, by their execution and delivery of this
Indenture, expressly agree to such terms and provisions and to be bound thereby.
However, to the extent any provision of any Note conflicts with the express
provisions of this Indenture, the provisions of this Indenture shall govern and
be controlling.

                  (b)      Global Notes. Notes issued in global form shall be
substantially in the form of Exhibit A attached hereto (and shall include the
Global Note Legend thereon and the "Schedule of Exchanges of Interests in the
Global Note" attached thereto). Notes issued in definitive form shall be
substantially in the form of Exhibit A 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 shall represent such of the
outstanding Notes as shall be specified therein and each shall provide that it
shall represent 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 and redemptions. Any endorsement of a Global
Note to reflect the amount of any increase or decrease in the aggregate
principal amount of outstanding Notes represented thereby shall be made by the
Trustee in accordance with instructions given by the Holder thereof as required
by Section 2.07 hereof.

                  (c)      Regulation S Global Notes. Notes offered and sold in
reliance on Regulation S shall be issued initially in the form of the Legended
Regulation S Global Note, which shall be deposited on behalf of the purchasers
of the Notes represented thereby with the Trustee, as custodian for The
Depository Trust Company ("DTC") in New York, New York, 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, duly executed
by the Company and authenticated by the Trustee as hereinafter provided.
Following the termination of the Restricted Period, beneficial interests in the
Legended Regulation S Global Note shall be exchanged for beneficial interests in
Unlegended Regulation S Global Notes pursuant to the Applicable Procedures.
Simultaneously with the authentication of Unlegended Regulation S Global Notes,
the Trustee shall cancel the Legended Regulation S Global Note. The aggregate
principal amount of the Regulation S 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.

                                       27

<PAGE>

                  (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
Cedel Bank" and "Customer Handbook" of Clearstream shall be applicable to
transfers of beneficial interests in the Regulation S Global Notes that are held
by Participants through Euroclear or Clearstream.

Section 2.02. Execution and Authentication.

                  Two Officers of the Company shall sign the Notes for 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 shall nevertheless be
valid.

                  A Note shall not be valid until authenticated by the manual
signature of the Trustee. Such signature shall be conclusive evidence that the
Note has been authenticated under this Indenture.

                  The aggregate principal amount of Notes which may be
authenticated and delivered under this Indenture is unlimited. The Company may,
subject to Article Four of this Indenture and applicable law, issue Additional
Notes under this Indenture, including Exchange Notes. The Notes issued on the
Closing Date and any Additional Notes subsequently issued shall be treated as a
single class for all purposes under this Indenture.

                  The Trustee shall, upon a written order of the Company signed
by two Officers of the Company (an "AUTHENTICATION ORDER"), authenticate Notes
for original issue on the date hereof of $600 million. At any time and from time
to time after the execution of this Indenture, the Trustee shall, upon receipt
of an Authentication Order, authenticate Notes for original issue in aggregate
principal amount specified in such Authentication Order. The Authentication
Order shall specify the amount of Notes to be authenticated and the date on
which the Notes are to be authenticated.

                  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 or an
Affiliate of the Company.

Section 2.03. Methods of Receiving Payments on the Notes.

                  If a Holder of $1.0 million or more of Notes has given wire
transfer instructions to the Company, the Company shall pay all principal,
interest and premium and Liquidated Damages, if any, on that Holder's Notes in
accordance with those instructions. All other payments on Notes shall be made at
the office or agency of the Paying Agent and Registrar within the City and State
of New York unless the Company elects to make interest payments by check mailed
to the Holders at their addresses set forth in the register of Holders.

                                       28

Section 2.04. Registrar and Paying Agent.

                  (a)      The Company shall maintain an office or agency where
Notes may be presented for registration of transfer or for exchange
("REGISTRAR") and an office or agency where Notes may be presented for payment
("PAYING AGENT"). The Registrar shall 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 prior notice to any Holder. The
Company shall notify the Trustee in writing of the name and address of any Agent
not a party to this Indenture. If the Company fails to appoint or maintain
another entity as Registrar or Paying Agent, the Trustee shall act as such. The
Company or any of its Subsidiaries may act as Paying Agent or Registrar.

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

                  (c)      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 2.05. Paying Agent to Hold Money in Trust.

                  The Company shall require each Paying Agent other than the
Trustee to agree in writing that the Paying Agent shall hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the
payment of principal, premium or Liquidated Damages, if any, or interest on the
Notes, and shall 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 one of its
Subsidiaries) shall have no further liability for the money. If the Company or
one of its Subsidiaries acts as Paying Agent, it shall 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 shall serve as Paying Agent for the Notes.

Section 2.06. Holder Lists.

                  The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of all Holders and shall otherwise comply with TIA Section 312(a). If
the Trustee is not the Registrar, the Company shall furnish to the Trustee at
least seven 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).

                  (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. All Global Notes
shall be exchanged by the Company for Definitive Notes if (i) 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 120 days after the date of
such notice from the Depositary; (ii) 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 Legended Regulation S Global Note
be exchanged by the Company for Definitive Notes prior to the expiration of the
Restricted Period; or (iii) there shall have occurred and be continuing a
Default or Event of Default with respect to the Notes. Upon the occurrence of
either of the preceding events in (i), (ii) or (iii) above, Definitive Notes
shall be issued in such names as the Depositary shall instruct the Trustee.
Global Notes also may be exchanged or replaced, in whole or in part, as provided
in Sections 2.08 and 2.11 hereof. Every Note authenticated and delivered in
exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to
this Section 2.07 or Section 2.08 or 2.11 hereof, shall be authenticated and
delivered in the form of, and shall be, a Global Note. A Global Note may not be
exchanged for another Note other than as provided in this Section 2.07(a),
however, beneficial interests in a Global Note may be transferred and exchanged
as provided in Section 2.07(b), (d) 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 shall be effected through the Depositary, in accordance with the
provisions of this Indenture and the Applicable Procedures. Beneficial interests
in the Restricted Global Notes shall 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 shall require
compliance with either subparagraph (i) or (ii) below, as applicable, as well as
one or more of the other following subparagraphs, as applicable:

                  (i)      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. 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 2.07(b)(i).

                  (ii)     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
         2.07(b)(i) above, the transferor of such beneficial interest must
         deliver to the Registrar either (A) (1) a written order from a
         Participant or an Indirect Participant

                                       30

         given to the Depositary in accordance with the Applicable Procedures
         directing the Depositary to credit or cause to be credited a beneficial
         interest in another Global Note in an amount equal to the beneficial
         interest to be transferred or exchanged and (2) instructions given in
         accordance with the Applicable Procedures containing information
         regarding the Participant account to be credited with such increase or
         (B) (1) a written order from a Participant or an Indirect Participant
         given to the Depositary in accordance with the Applicable Procedures
         directing the Depositary to cause to be issued a Definitive Note in an
         amount equal to the beneficial interest to be transferred or exchanged
         and (2) 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 Legended Regulation S Global Note prior to the expiration of the
         Restricted Period. Upon consummation of an Exchange Offer by the
         Company in accordance with Section 2.07(f) hereof, the requirements of
         this Section 2.07(b)(ii) 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 Securities Act, the Trustee shall adjust the principal amount at
         maturity of the relevant Global Notes pursuant to Section 2.07(i)
         hereof.

                  (iii)    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 beneficial interest in another Restricted Global Note if the
         transfer complies with the requirements of Section 2.07(b)(ii) above
         and the Registrar receives the following:

                           (A)      if the transferee shall take delivery in the

affiliates (as defined in Rule 144) of the Company, and accepted for exchange in
the Exchange Offer and (ii) Definitive Notes in an aggregate principal amount

and the Trustee shall authenticate and deliver to the Persons designated by the
Holders of Restricted Global Notes so accepted Unrestricted Global Notes in the

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, the Trustee,
any Agent and any authenticating agent from any loss that any of them may suffer
if a Note is replaced. The Company may charge for its expenses in replacing a
Note.

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

Section 2.09. Outstanding Notes.

                  (a)      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 as not outstanding. Except as set forth in Section 2.10 hereof, a
Note does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note; 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(b) hereof.

                  (b)      If a Note is replaced pursuant to Section 2.08
hereof, it ceases to be outstanding unless the Trustee receives proof
satisfactory to it that the replaced Note is held by a bona fide purchaser.

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

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

Section 2.10. Treasury Notes.

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

Section 2.11. Temporary Notes.

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

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

Section 2.12. Cancellation.

                  The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall dispose of
canceled Notes in accordance with its procedures for the disposition of canceled
securities in effect as of the date of such disposition (subject to the record
retention requirement of the Exchange Act). Certification of the disposition of
all canceled Notes shall be delivered to the Company. The Company may not issue
new Notes to replace Notes that it has paid or that have been delivered to the
Trustee for cancellation.

Section 2.13. Defaulted Interest.

                  If the Company defaults in a payment of interest on the Notes,
it shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date, in each case at the rate provided
in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Note and
the date of the proposed payment. The Company shall fix or cause to be fixed
each such special record date and payment date, provided that no such special
record date shall 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) shall mail or cause to be mailed to Holders a
notice that states the special record date, the related payment date and the
amount of such interest to be paid.

Section 2.14. CUSIP Numbers.

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

                                       43

<PAGE>

numbers. The Company shall promptly notify the Trustee of any change in the
"CUSIP" numbers.

Section 3.01. Notices to Trustee.

                  If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Notes to be redeemed and (iv) the redemption price.

Section 3.02. Selection of Notes to Be Redeemed.

                  (a)      If less than all of the Notes are to be redeemed at
any time, the Trustee shall select the Notes to be redeemed among the Holders of
the Notes in compliance with the requirements of the principal national
securities exchange, if any, on which the Notes are listed or, if the Notes are
not so listed, on a pro rata basis, by lot or in accordance with any other
method the Trustee considers fair and appropriate. In the event of partial
redemption by lot, the particular Notes to be redeemed shall be selected, unless
otherwise provided herein, not less than 30 nor more than 60 days prior to the
redemption date by the Trustee from the outstanding Notes not previously called
for redemption.

                  (b)      The Trustee shall promptly notify the Company in
writing of the Notes selected for redemption and, in the case of any Note
selected for partial redemption, the principal amount at maturity thereof to be
redeemed. No Notes in amounts of $1,000 or less shall be redeemed in part. Notes
and portions of Notes selected shall be in amounts of $1,000 or whole multiples
of $1,000; except that if all of the Notes of a Holder are to be redeemed, the
entire outstanding amount of Notes held by such Holder, even if not a multiple
of $1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

Section 3.03. Notice of Redemption.

                  (a)      At least 30 days but not more than 60 days before a
redemption date, the Company shall mail or cause to be mailed, by first class
mail, a notice of redemption to each Holder whose Notes are to be redeemed at
its registered address.

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

                  (i)      the redemption date;

                  (ii)     the redemption price;

                                       44

<PAGE>

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

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

                  (v)      that Notes called for redemption must be surrendered
         to the Paying Agent to collect the redemption price and become due on
         the date fixed for redemption;

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

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

                  (viii)   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.

                  (b)      At the Company's request, the Trustee shall give the
notice of redemption in the Company's name and at its expense; provided,
however, that the Company shall have delivered to the Trustee, at least 45 days
prior to the redemption date, an Officers' Certificate requesting that the
Trustee give such notice and setting forth the information to be stated in such
notice as provided in the preceding paragraph. The notice, if mailed in the
manner provided herein shall be presumed to have been given, whether or not the
Holder receives such notice.

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.

Section 3.05. Deposit of Redemption Price.

                  (a)      One Business Day prior to the redemption date, the
Company shall deposit with the Trustee or with the Paying Agent money sufficient
to pay the redemption price of and accrued interest and Liquidated Damages, if
any, on all Notes to be redeemed on that date. The Trustee or the Paying Agent
shall promptly return to the Company any money deposited with the Trustee or the
Paying Agent by the Company in excess of the amounts necessary to pay the
redemption price of, and accrued interest on, all Notes to be redeemed.

                  (b)      If the Company complies with the provisions of the
preceding paragraph, on and after the redemption date, interest shall cease to
accrue on the Notes or the portions of Notes called for redemption. If a Note is
redeemed on or after an interest record date but on or prior to the related
interest payment date, then any accrued and unpaid interest shall be paid to the
Person in whose name such Note was registered at the close of business on such
record date.

                                       45

<PAGE>

If any Note called for redemption shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall be paid on the unpaid principal, from the redemption
date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the Notes
and in Section 4.01 hereof.

Section 3.06. Notes Redeemed in Part.

                  Upon surrender of a Note that is redeemed in part, the Company
shall issue and the Trustee shall authenticate for the Holder at the expense of
the Company a new Note equal in principal amount to the unredeemed portion of
the Note surrendered. No Notes in denominations of $1,000 or less shall be
redeemed in part.

Section 3.07. Optional Redemption.

                  (a)      Except as set forth in clause (b) of this Section
3.07, the Company shall not have the option to redeem the Notes pursuant to this
Section 3.07 prior to June 15, 2007. Thereafter, the Company may redeem all or a

redeem up to 35% of the aggregate principal amount of Notes originally issued
hereunder at a redemption price of 110.250% of the principal amount thereof,

after the occurrence of such redemption, excluding Notes held by the Company and
its Subsidiaries; and (B) the redemption must occur within 45 days of the date

                  In the event that, pursuant to Section 4.10 or 4.14 hereof,
the Company shall be required to commence an offer to all Holders to purchase
their respective Notes (a "REPURCHASE OFFER"), it shall follow the procedures
specified in such Sections and, to the extent not inconsistent therewith, the
procedures specified below.

                  The Repurchase Offer shall remain open for a period of no less
than 30 days and no more than 60 days following its commencement, except to the
extent that a longer period is required by applicable law (the "OFFER PERIOD").
No later than three Business Days after the termination of the Offer Period (the
"PURCHASE DATE"), the Company shall purchase the principal amount of Notes
required to be purchased pursuant to Section 4.10 or 4.14 hereof (the "OFFER
AMOUNT") or, if less than the Offer Amount has been tendered, all Notes tendered
in response to the Repurchase Offer. Payment for any Notes so purchased shall be
made in the same manner as interest payments are made.

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

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

                  (i)      that the Repurchase Offer is being made pursuant to
         this Section 3.08 and Section 4.10 or Section 4.14 hereof, and the
         length of time the Repurchase Offer shall remain open;

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

                  (iii)    that any Note not tendered or accepted for payment
         shall continue to accrue interest and Liquidated Damages, if any;

                  (iv)     that, unless the Company defaults in making such
         payment, any Note (or portion thereof) accepted for payment pursuant to
         the Repurchase Offer shall cease to accrue interest and Liquidated
         Damages, if any, after the Purchase Date;

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

                  (vi)     that Holders electing to have a Note purchased
         pursuant to any Repurchase Offer shall be required to surrender the
         Note, with the form entitled "Option

                                       47

         of Holder to Elect Purchase" on the reverse of the Note completed, or
         transfer by book-entry transfer, to the Company, a depositary, if
         appointed by the Company, or a Paying Agent at the address specified in
         the notice at least three days before the Purchase Date;

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

                  (viii)   that, if the aggregate amount of Notes surrendered by
         Holders exceeds the Offer Amount, the Trustee shall, subject in the
         case of a Repurchase Offer made pursuant to Section 4.10 to the
         provisions of Section 4.10, select the Notes to be purchased on a pro
         rata basis (with such adjustments as may be deemed appropriate by the
         Trustee so that only Notes in denominations of $1,000, or integral
         multiples thereof, shall be purchased); and

                  (ix)     that Holders whose Notes were purchased only in part
         shall be issued new Notes equal in principal amount to the unpurchased
         portion of the Notes surrendered (or transferred by book-entry
         transfer).

                  On the Purchase Date, the Company shall, to the extent lawful,
subject in the case of a Repurchase Offer made pursuant to Section 4.10 to the
provisions of Section 4.10, accept for payment on a pro rata basis to the extent
necessary, the Offer Amount of Notes (or portions thereof) tendered pursuant to
the Repurchase Offer, or if less than the Offer Amount has been tendered, all
Notes tendered, and shall deliver to the Trustee an Officers' Certificate
stating that such Notes (or portions thereof) were accepted for payment by the
Company in accordance with the terms of this Section 3.08. The Company, the
Depositary or the Paying Agent, as the case may be, shall promptly (but in any
case not later than three days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of Notes tendered by such
Holder, as the case may be, and accepted by the Company for purchase, and the
Company, shall promptly issue a new Note. The Trustee, upon written request from
the Company shall authenticate and mail or deliver such new Note to such Holder,
in a principal amount at maturity equal to any unpurchased portion of the Note
surrendered. Any Note not so accepted shall be promptly mailed or delivered by
the Company to the respective Holder thereof. The Company shall publicly
announce the results of the Repurchase Offer on the Purchase Date.

                  The Company shall comply with the requirements of Rule 14e-1
under the Exchange Act, and any other securities laws and regulations thereunder
to the extent such laws or regulations are applicable in connection with the
repurchase of the Notes pursuant to a Repurchase Offer and shall not be deemed
to have breached its obligations under Section 3.08, 4.10 or 4.14 by virtue of
such compliance.

unless, at the time of and after giving effect to such Restricted Payment:

                           (A)      no Default or Event of Default shall have
                  occurred and be continuing or would occur as a consequence
                  thereof;

                           (B)      the Company would, at the time of such
                  Restricted Payment and after giving pro forma effect thereto

                  Incur at least $1.00 of additional Indebtedness pursuant to
                  the Fixed Charge Coverage Ratio test set forth in Section
                  4.09(a); and

                           (C)      such Restricted Payment, together with the
                  aggregate amount of all other Restricted Payments made by the
                  Company and its Restricted Subsidiaries after the date of this

                           Restricted Payment (or, if such Consolidated Net
                           Income for such period is a deficit, less 100% of
                           such deficit), plus

be the fair market value on the date of the Restricted Payment of the asset(s)
or securities proposed to be transferred or issued to or by the Company or such
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair

         in any such amendments, modifications, restatements, renewals,
         extensions, supplements, refundings, replacement or refinancings are no

         Accounts Receivable Facility or such other agreements as in effect on
         the date of this Indenture;

         restrictions contained in the agreements governing such Permitted
         Refinancing Indebtedness are no more restrictive, taken as a whole,

         letters of credit being deemed to have a principal amount equal to the
         maximum potential liability of the Company and its Restricted
         Subsidiaries thereunder) not to exceed the greater of (A) $200.0
         million, less the aggregate amount of all Net Proceeds of Asset Sales
         applied by the Company or any Restricted Subsidiary to permanently
         repay any such Indebtedness (and, in the case of any revolving credit
         Indebtedness, to effect a corresponding commitment reduction
         thereunder) pursuant to Section 4.10 and (B) the sum of the amounts
         equal to (x) 40% of the consolidated book value of the inventory of the
         Company and the Guarantors and (y) 70% of the consolidated book value
         of the accounts receivable of the Company and the Guarantors, in each
         case as set forth on the most recent available quarterly or annual
         consolidated balance sheet of the Company and its Restricted
         Subsidiaries, prepared in conformity with GAAP;

                  (ii)     the Incurrence of Existing Indebtedness;

                  (iii)    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 of this Indenture and the Exchange Notes and
         the related Note Guarantees to be issued pursuant to the Registration
         Rights Agreement;

                  (iv)     the Incurrence by the Company or any Restricted
         Subsidiary of the Company of Permitted Refinancing Indebtedness in
         exchange for, or the net proceeds of which are used to refund,
         refinance or replace Indebtedness (other than intercompany
         Indebtedness) that was permitted by this Indenture to be Incurred under
         Section 4.09(a) or Section 4.09(b)(ii), (iii), (iv) or (vii);

                  (v)      the Incurrence by the Company or any of its
         Restricted Subsidiaries of intercompany Indebtedness owing to and held
         by the Company or any of its Restricted Subsidiaries; provided,
         however, that:

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

                           (B)      (i) any subsequent issuance or transfer of
                  Equity Interests that results in any such Indebtedness being
                  held by a Person other than the Company or a Restricted
                  Subsidiary thereof and (ii) any sale or other transfer of any
                  such Indebtedness to a Person that is not either the Company
                  or a Restricted Subsidiary thereof, shall be deemed, in each
                  case, to constitute an Incurrence of such Indebtedness by the
                  Company or such Restricted Subsidiary, as the case may be,
                  that was not permitted by this Section 4.09(b)(v);

                  (vi)     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 this Section 4.09; or

                  (vii)    the Incurrence by the Company or any Guarantor of
         additional Indebtedness in an aggregate principal amount (or accreted
         value, as applicable) at any time outstanding, including all Permitted
         Refinancing Indebtedness Incurred to refund, refinance or replace any
         Indebtedness Incurred pursuant to this Section 4.09(b)(vii), not to
         exceed $10.0 million.

                  For purposes of determining compliance with this Section 4.09,
in the event that any proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in Sections 4.09(b)(i) through
(vii) above, or is entitled to be Incurred pursuant to Section 4.09(a), the
Company shall be permitted to classify at the time of its Incurrence such item
of Indebtedness in any manner that complies with this covenant. Indebtedness
under Credit Facilities outstanding on the date on which Notes are first issued
under this Indenture shall be deemed to have been Incurred on such date in
reliance on the exception provided by 4.09(b)(i).

                  (c)      Notwithstanding any other provision of this Section
4.09, the maximum amount of Indebtedness that may be Incurred pursuant to this
Section 4.09 shall not be deemed to be exceeded, with respect to any outstanding
Indebtedness due solely to the result of fluctuations in the exchange rates of
currencies.

                  (d)      The Company shall not Incur any Indebtedness that is
subordinate or junior in right of payment to any other Indebtedness of the
Company unless it subordinate in

                                       57

<PAGE>

right of payment to the Notes. No Guarantor shall Incur any Indebtedness that is
subordinate or junior in right of payment to any other Indebtedness of such
Guarantor unless it is subordinate in right of payment to such Guarantor's Note
Guarantee. For avoidance of doubt, Indebtedness will not be considered
subordinate or junior in right of payment to any other Indebtedness solely by
virtue of being unsecured or secured to a greater or lesser extent or with
greater or lower priority.

Section 4.10. Asset Sales.

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

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

                  (ii)     such fair market value is determined by the Company's
         Board of Directors and evidenced by a resolution of the Board of
         Directors set forth in an Officers' Certificate delivered to the
         Trustee; and

                  (iii)    at least 75% of the consideration therefor received
         by the Company or such Restricted Subsidiary is in the form of cash or
         Replacement Assets or a combination of both. For purposes of this
         Section 4.10(a)(iii), each of the following shall be deemed to be cash:

                           (A)      any liabilities (as shown on the Company's
                  or such Restricted Subsidiary's most recent balance sheet) of
                  the Company or any Restricted Subsidiary (other than
                  contingent liabilities, liabilities that are by their terms
                  subordinated to the Notes or any Note Guarantee and
                  liabilities to the extent owed to the Company or any Affiliate
                  of the Company) that are assumed by the transferee of any such
                  assets pursuant to a customary written agreement that releases
                  the Company or such Restricted Subsidiary from further
                  liability; and

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

                  (b)      Within 360 days after the receipt of any Net Proceeds
from an Asset Sale, the Company may apply such Net Proceeds at its option:

                  (i)      to repay Indebtedness under the Credit Facilities or
         Unsubordinated Indebtedness secured by such assets and, if the
         Indebtedness repaid is revolving credit Indebtedness, to
         correspondingly reduce commitments with respect thereto; or

                  (ii)     to purchase Replacement Assets or make a capital
         expenditure in or that is used or useful in a Permitted Business.

                                       58

<PAGE>

                  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.

                  (c)      Any Net Proceeds from Asset Sales that are not
applied or invested as provided in Section 4.10(b) above shall constitute
"EXCESS PROCEEDS." Within 10 days after the aggregate amount of Excess Proceeds
exceeds $10.0 million, the Company shall make an offer (an "ASSET SALE OFFER")
to all Holders of Notes and all holders of other Unsubordinated Indebtedness
containing provisions similar to those set forth in this Indenture with respect
to offers to purchase with the proceeds of sales of assets, to purchase the
maximum principal amount of Notes and such other Unsubordinated Indebtedness
that may be purchased out of the Excess Proceeds. The offer price in any Asset
Sale Offer shall be equal to 100% of principal amount plus accrued and unpaid
interest and Liquidated Damages, if any, to the date of purchase, and shall 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 such other Unsubordinated Indebtedness tendered into such Asset Sale
Offer exceeds the amount of Excess Proceeds, Notes and such other Unsubordinated
Indebtedness to be purchased shall be selected on a pro rata basis based on the
principal amount of Notes and such other Unsubordinated 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 shall not, and shall not permit any of
its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into, make, amend, renew or extend any
transaction, contract, agreement, understanding, loan, advance or Guarantee
with, or for the benefit of, any Affiliate (each, an "AFFILIATE TRANSACTION"),
unless:

                  (i)      such Affiliate Transaction is on terms that are no
         less favorable to the Company or the relevant Restricted Subsidiary
         than those that would have been obtained in a comparable arm's-length
         transaction by the Company or such Restricted Subsidiary with a Person
         that is not an Affiliate of the Company; and

                  (ii)     the Company delivers to the Trustee:

                           (A)      with respect to any Affiliate Transaction or
                  series of related Affiliate Transactions involving aggregate
                  consideration in excess of $5.0 million, a resolution of the
                  Board of Directors set forth in an Officers' Certificate
                  certifying that such Affiliate Transaction or series of
                  related Affiliate Transactions complies with this Section 4.11
                  and that such Affiliate Transaction or series of related
                  Affiliate Transactions has been approved by a majority of the
                  disinterested 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 $10.0 million, an opinion as to the
                  fairness to the Company or such Restricted

                                       59

<PAGE>

                  Subsidiary of such Affiliate Transaction or series of related
                  Affiliate Transactions from a financial point of view issued
                  by an independent accounting, appraisal or investment banking
                  firm.

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

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

                  (ii)     payment of reasonable fees and compensation to, and
         indemnity provided on behalf of, the executive officers and directors
         of the Company and its Restricted Subsidiaries;

                  (iii)    Restricted Payments that are permitted by the
         provisions of Section 4.07;

                  (iv)     transfers of accounts receivable and related assets
         to a Receivables Subsidiary in connection with a Qualified Receivables
         Transaction and the charging of fees and expenses in the ordinary
         course of business in connection with such transfers; and

                  (v)      any sale of Capital Stock (other than Disqualified
         Stock) of the Company.

Section 4.12. Liens.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer
to exist or become effective any Lien of any kind (other than Permitted Liens)
upon any of their property or assets, 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 until such time as such
obligations are no longer secured by a Lien.

Section 4.13. Business Activities.

                  The Company shall not, and shall not permit any Restricted
Subsidiary to, engage in any business other than Permitted Businesses except to
such extent as would not be material to the Company and its Restricted
Subsidiaries taken as a whole.

Section 4.14. Offer to Repurchase upon a Change of Control.

                  (a)      If a Change of Control occurs, each Holder of Notes
shall have the right to require the Company to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of that Holder's Notes pursuant to an
offer by the Company (a "CHANGE OF CONTROL OFFER") at an offer price (a "CHANGE
OF CONTROL PAYMENT") in cash equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest and Liquidated Damages, if any,
thereon, to the date of purchase. Within ten days following any Change of
Control, the Company shall mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Notes on a date (the "CHANGE OF

                                       60

<PAGE>

CONTROL PAYMENT DATE") specified in such notice, which shall be no earlier than
30 days and no later than 60 days from the date such notice is mailed, pursuant
to the procedures described in Section 3.08.

                  (b)      By 11:00 a.m. Eastern Time on the Change of Control
Payment Date, the Company shall, to the extent lawful:

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

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

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

                  (c)      The Paying Agent shall promptly mail or wire transfer
to each Holder of more than $1.0 million of Notes so tendered the Change of
Control Payment for such Notes, and the Trustee shall 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 such new Note shall be in a principal amount of $1,000 or an
integral multiple thereof.

                  (d)      The Company will publicly announce the results of the
Change of Control Offer on or as soon as practicable after the Change of Control
Payment Date.

                  (e)      Notwithstanding anything to the contrary in this
Section 4.14, the Company shall not be required to make a Change of Control
Offer upon a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in this Section 4.14 and all other provisions of this
Indenture applicable to a Change of Control Offer made by the Company and
purchases all Notes validly tendered and not withdrawn under such Change of
Control Offer.

Section 4.15. Limitation on Issuances and Sales of Equity Interests in
              Restricted Subsidiaries.

                  (a)      The Company shall not transfer, convey, sell, lease
or otherwise dispose of, and shall not permit any of its Restricted Subsidiaries
to issue, transfer, convey, sell, lease or otherwise dispose of, any Equity
Interests in any Restricted Subsidiary of the Company to any Person (other than
the Company or a Restricted Subsidiary of the Company or, if necessary, shares
of its Capital Stock constituting directors' qualifying shares or issuances of
shares of Capital Stock of foreign Restricted Subsidiaries to foreign nationals,
to the extent required by applicable law), except:

                  (i)      if, immediately after giving effect to such issuance,
         transfer, conveyance, sale, lease or other disposition, such Restricted
         Subsidiary would no longer constitute a Restricted Subsidiary and any
         Investment in such Person remaining after giving effect to

                                       61

<PAGE>

         such issuance or sale would have been permitted to be made under
         Section 4.07 hereof if made on the date of such issuance or sale; or

                  (ii)     sales of Common Stock of a Restricted Subsidiary by
         the Company or a Restricted Subsidiary, provided that the Company or
         such Restricted Subsidiary complies with Section 4.10.

Section 4.16. Designation of Restricted and Unrestricted Subsidiaries.

                  (a)      The Board of Directors of the Company may designate
any Restricted Subsidiary to be an Unrestricted Subsidiary, provided that:

                  (i)      any Guarantee by the Company or any Restricted
         Subsidiary of any Indebtedness of the Subsidiary being so designated
         shall be deemed to be an Incurrence of Indebtedness by the Company or
         such Restricted Subsidiary (or both, if applicable) at the time of such
         designation, and such Incurrence of Indebtedness would be permitted
         under Section 4.09;

                  (ii)     the aggregate fair market value of all outstanding
         Investments owned by the Company and its Restricted Subsidiaries in the
         Subsidiary being so designated (including any Guarantee by the Company
         or any Restricted Subsidiary of any Indebtedness of such Subsidiary)
         shall be deemed to be a Restricted Investment made as of the time of
         such designation and such Investment would be permitted under Section
         4.07;

                  (iii)    such Subsidiary does not own any Equity Interests of,
         or hold any Liens on any Property of, the Company or any Restricted
         Subsidiary;

                  (iv)     the Subsidiary being so designated:

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

                           (B)      is a Person with respect to which neither
                  the Company nor any of its Restricted Subsidiaries has any
                  direct or indirect obligation (i) to subscribe for additional
                  Equity Interests or (ii) to maintain or preserve such Person's
                  financial condition or to cause such Person to achieve any
                  specified levels of operating results;

                           (C)      has not Guaranteed or otherwise directly or
                  indirectly provided credit support for any Indebtedness of the
                  Company or any of its Restricted Subsidiaries, except to the
                  extent such Guarantee or credit support would be released upon
                  such designation; and

                                       62

<PAGE>

                           (D)      other than in the case of a Receivables
                  Subsidiary, has at least one director on its Board of
                  Directors that is not a director or officer of the Company or
                  any of its Restricted Subsidiaries and has at least one
                  executive officer that is not a director or officer of the
                  Company or any of its Restricted Subsidiaries; and

                  (v)      no Default or Event of Default would be in existence
         following such designation.

                  (b)      Any designation of a Restricted Subsidiary of the
Company as an Unrestricted Subsidiary shall be evidenced to the Trustee by
filing with the Trustee a certified copy of the Board Resolution giving effect
to such designation and an Officers' Certificate certifying that such
designation complied with the preceding conditions and was permitted by this
Indenture. If, at any time, any Unrestricted Subsidiary (x) would fail to meet
any of the preceding requirements described in Sections 4.16(a)(iv)(A), (B) and
(C) above or (y) fails to meet the requirement described in Section
4.16(a)(iv)(D) above and such failure continues for a period of 60 days, such
Subsidiary shall thereafter cease to be an Unrestricted Subsidiary for purposes
of this Indenture and any Indebtedness, Investments, or Liens on the property,
of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary of
the Company as of such date and, if such Indebtedness, Investments or Liens are
not permitted to be incurred as of such date under this Indenture, the Company
shall be in Default under this Indenture.

                  (c)      The Board of Directors of the Company may at any time
designate any Unrestricted Subsidiary to be a Restricted Subsidiary, provided
that:

                  (i)      such designation shall be deemed to be an Incurrence
         of Indebtedness by a Restricted Subsidiary of the Company of any
         outstanding Indebtedness of such Unrestricted Subsidiary and such
         designation shall only be permitted if such Indebtedness is permitted
         under Section 4.09; calculated on a pro forma basis as if such
         designation had occurred at the beginning of the four-quarter reference
         period;

                  (ii)     all outstanding Investments owned by such
         Unrestricted Subsidiary shall be deemed to be made as of the time of
         such designation and such Investments shall only be permitted if such
         Investments would be permitted under Section 4.07;

                  (iii)    all Liens upon property or assets of such
         Unrestricted Subsidiary existing at the time of such designation would
         be permitted under Section 4.12; and

         following such designation.

Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder of Notes 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
and is paid to all Holders of the Notes 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 4.18. Guarantees.

                  (a)      If the Company or any of its Restricted Subsidiaries
acquires or creates another Domestic Subsidiary (other than a Receivables
Subsidiary) on or after the date of this Indenture, then that newly acquired or
created Domestic Subsidiary shall become a Guarantor and execute a supplemental
indenture in the form of Exhibit F hereto and deliver an Opinion of Counsel to
the Trustee as to the authorization and enforceability of such supplemental
indenture and any other matters reasonably requested by the Trustee and in
compliance with Section 12.05 hereof. The Company shall not permit any of its
Restricted Subsidiaries, directly or indirectly, to Guarantee the payment of any
other Indebtedness of the Company, unless such Restricted Subsidiary is a
Guarantor or simultaneously executes and delivers a supplemental indenture in
the form attached hereto as Exhibit F providing for a Note Guarantee of payment
of the Notes by such Restricted Subsidiary, which Note Guarantee shall be senior
to or pari passu with such Subsidiary's Guarantee of such other Indebtedness.

                  (b)      Notwithstanding the preceding paragraph, any Note
Guarantee may provide by its terms that it will be automatically and
unconditionally released and discharged under the circumstances described under
Section 10.05 hereof.

Section 4.19. Sale and Leaseback Transactions.

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

                  (i)      the Company or that Restricted Subsidiary, as
         applicable, could have 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);

                  (ii)     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

                  (iii)    the transfer of assets in that sale and leaseback
         transaction is permitted by, and the Company applies the proceeds of
         such transaction in compliance with Section 4.10.

Section 4.20. [INTENTIONALLY OMITTED]

Section 4.21. Suspension of Certain Covenants and Agreements.

                  (a)      During any period of time that the Notes are rated
Investment Grade by both Rating Agencies and no Default or Event of Default
shall have occurred and then be continuing (the foregoing conditions being
referred to collectively as the "SUSPENSION CONDITION"), the Company and its
Restricted Subsidiaries will not be subject to Sections 4.07, 4.09, 4.10, 4.11,
4.15, clauses (i) and (iii) of Section 4.19 and clause (iii) of Section 5.01(a)
(collectively, the "SUSPENDED COVENANTS").

                  (b)      If the Company and its Restricted Subsidiaries are
not subject to the Suspended Covenants with respect to the Notes for any period
of time as a result of Section 4.21(a) and, subsequently, one or both Rating
Agencies withdraw their Investment Grade rating or downgrade the Investment
Grade rating assigned to the Notes such that the Notes are no longer rated
Investment Grade by both Rating Agencies, then the Company and each of its
Restricted Subsidiaries will thereafter again be subject to the Suspended
Covenants. Compliance with the Suspended Covenants with respect to Restricted
Payments made after the time of such withdrawal or downgrade will be calculated
in accordance with the terms of Section 4.07 as if such covenant had been in
effect during the entire period of time from the date of this Indenture.

         that its Note Guarantee shall apply to the obligations of the Company
         or the surviving Person in accordance with the Notes and this
         Indenture.

the assets of the Company in accordance with Section 5.01 hereof, the successor
corporation formed by such consolidation or into or with which the Company is
merged or to which such sale, assignment, transfer, conveyance or other
disposition is made shall succeed to, and be substituted for (so that from and
after the date of such consolidation, merger, sale, conveyance or other
disposition, the provisions of this Indenture referring to the "Company" shall
refer instead to the successor corporation and not to the Company), and may
exercise every right and power of, the Company under this Indenture with the
same effect as if such successor Person had been named as the Company herein;
provided, however, that the predecessor Company shall not be relieved from the
obligation to pay the principal of and interest and Liquidated Damages, if any,
on the Notes except in the case of a sale, assignment, transfer, conveyance or
other disposition of all of the Company's assets that meets the requirements of
Section 5.01 hereof.

         outstanding to comply with any of the other agreements in this
         Indenture;

                  (v)      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

                           (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

         Bankruptcy Law:

                           (A)      commences a voluntary case,

                  of its creditors, or

                  become due; and

                  (ix)     a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that:

                           (A)      is for relief against the Company or any of
                  its Restricted Subsidiaries that is a Significant Subsidiary
                  (or Restricted Subsidiaries that together would constitute a

                  consecutive days.

Section 6.02. Acceleration.

                  (a)      In the case of an Event of Default specified in
clauses (viii) or (ix) of Section 6.01 hereof, with respect to the Company or
any Significant Subsidiary of the Company (or any Restricted Subsidiaries that
together would constitute a Significant Subsidiary), 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 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 immediately by notice in writing to the Company
specifying the Event of Default.

                  (b)      With respect to periods after June 15, 2007, in the
case of any Event of Default occurring 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(a) hereof,
an equivalent premium shall also become and be immediately due and payable to
the extent permitted by law upon the acceleration of the Notes. With respect to
periods prior to June 15, 2007, if an Event of Default occurs during any time
that the Notes are outstanding, 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(c) hereof,
then the premium specified in Section 3.07(c) hereof as being payable upon an
optional redemption prior to June 15, 2007 shall become immediately due and
payable to the extent permitted by law upon the acceleration of the Notes.

Section 6.03. Other Remedies.

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

                  (b)      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.

                  Holders of a majority in principal amount of the then
outstanding Notes by notice to the Trustee may, on behalf of the Holders of all
of the Notes, rescind and annul a declaration

                                       68

<PAGE>

of acceleration pursuant to Section 6.02 hereof, and its consequences, and waive
any related existing Default or Event of Default if:

                  (a)      the Company has paid or deposited with the Trustee a
sum sufficient to pay (i) all sums paid or advanced by the Trustee hereunder and
the reasonable compensation, expenses and disbursements and advances of the
Trustee, it agents and counsel, (ii) all overdue interest and Liquidated Damages
on all Notes, (iii) the principal of and premium, if any, on any Notes that have
become due otherwise than by such declaration or occurrence of acceleration and
interest and Liquidated Damages, if any, thereon at the rate prescribed therefor
by such Notes, and (iv) to the extent that payment for such interest is lawful,
interest upon overdue interest, if any, at the rate prescribed in Section 4.01
hereof,

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

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

                  The Company shall deliver to the Trustee an Officers'
Certificate stating that the requisite percentage of Holders have consented to
any such waiver and attaching copies of such consents. In case of any such
waiver, the Company, the Trustee and the Holders shall be restored to their
former positions and rights hereunder and under the Notes, respectively. This
Section 6.04 and Section 9.02 shall be in lieu of Section 316(a)(1)(B) of the
TIA and such Section 316(a)(1)(B) of the TIA is hereby expressly excluded from
this Indenture and the Notes, as permitted by the TIA. 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.

                  (a)      A Holder may not pursue any remedy with respect to
this Indenture or the Notes unless:

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

                                       69

<PAGE>

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

                  (iii)    such Holder or Holders offer and, if requested,
         provide to the Trustee security and indemnity satisfactory to the
         Trustee against any costs, liability or expense that might be incurred
         by it in connection with the request or direction;

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

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

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

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

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

Section 6.08. Collection Suit by Trustee.

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

Section 6.09. Trustee May File Proofs of Claim.

                  The Trustee is authorized to file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel) and
the Holders of the Notes allowed in any judicial proceedings relative to the
Company or any Guarantor (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 securities or 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

                                       70

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
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

Section 6.10. Priorities.

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

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

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

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

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

Section 6.11. Undertaking for Costs.

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

                                     TRUSTEE

Section 7.01. Duties of Trustee. Except to the extent, if any, provided
otherwise in the Trust Indenture Act of 1939 (as from time to time in effect):

                  (a)      If an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in 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:

                  (i)      the duties of the Trustee shall 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

                  (ii)     in the absence of bad faith on its part, the Trustee
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, the Trustee shall 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:

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

                  (ii)     the Trustee shall 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

                  (iii)    the Trustee shall 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 shall require the
Trustee to expend or risk its own funds or incur any liability. The Trustee
shall be under no obligation to exercise any of its rights and powers under this
Indenture at the request of any Holders, unless such Holder shall have offered
to the Trustee security and indemnity satisfactory to it against any loss,
costs, liability or expense that might be incurred by it in connection with the
request or direction.

                  (f)      Money held in trust by the Trustee need not be
segregated from other funds except to the extent required by law.

Section 7.02. Certain Rights of Trustee.

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

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

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

                  (d)      The Trustee shall 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.

                  (e)      Unless otherwise specifically provided in this
Indenture, any demand, request, direction or notice from the Company shall be
sufficient if signed by an Officer of the Company.

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

                  (g)      The Trustee shall not be deemed to have notice of any
Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of such event is sent to the
Trustee in accordance with Section 12.02 hereof, and such notice references the
Notes.

Section 7.03. Individual Rights of Trustee.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Notes and may become a creditor of, or otherwise deal
with, the Company or any of its Affiliates with the same rights it would have if
it were not Trustee. However, in the event that the Trustee acquires any
conflicting interest as described in the Trust Indenture Act of 1939 (as in
effect at such time), 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 shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture, it shall not be
accountable for the Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

Section 7.05. Notice of Defaults.

                  If a Default or Event of Default occurs and is continuing and
if it is known to the Trustee, the Trustee shall mail to Holders of Notes a
notice of the Default or Event of Default within 90 days after it occurs. Except
in the case of a Default or Event of Default in payment of principal, premium,
interest or Liquidated Damages 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 May 31 beginning with the
May 31 following the date hereof, and for so long as Notes remain outstanding,
the Trustee shall mail to the Holders of the Notes a brief report dated as of
such reporting date that complies with TIA 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 shall
comply with TIA Section 313(b)(2). The Trustee shall 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 of Notes shall be mailed to the Company and filed with the SEC and
each stock exchange on which the Notes are listed in accordance with TIA Section
313(d). The Company shall promptly notify the Trustee when the Notes are listed
on any stock exchange or any delisting thereof.

Section 7.07. Compensation and Indemnity.

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

                  (b)      The Company shall 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 (including this Section 7.07) and defending itself against any

                                       74

<PAGE>

claim (whether asserted by either of the Company 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, bad faith or willful misconduct.
The Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Company need not pay for any
settlement made without its consent, which consent shall not be unreasonably
withheld.

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

                  (d)      To secure the Company's payment obligations in this
Section, the Trustee shall have a Lien prior to the Notes on all money or
property held or collected by the Trustee, except that held in trust to pay
principal and interest on particular Notes. Such Lien shall survive the
satisfaction and discharge of this Indenture and resignation or removal of the
Trustee.

                  (e)      When the Trustee incurs expenses or renders services
after an Event of Default specified in Section 6.01(a)(viii) and (ix) 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 shall comply with the provisions of
TIA Section 313(b)(2) to the extent applicable.

Section 7.08. Replacement of Trustee.

                  (a)      A resignation or removal of the Trustee and
appointment of a successor Trustee shall become effective only upon the
successor Trustee's acceptance of appointment as provided in this Section 7.08.

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

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

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

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

                  (iv)     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 shall promptly
appoint a successor Trustee. Within one year after the successor Trustee takes
office, the Holders of a majority in principal amount of the

                                       75

<PAGE>

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 30
days after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company, or the Holders of Notes of at least 10% in principal amount of the then
outstanding Notes may petition at the expense of the Company 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 shall deliver a written
acceptance of its appointment to the retiring Trustee and to the Company.
Thereupon, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have all the rights, powers and
duties of the Trustee under this Indenture. The successor Trustee shall mail a
notice of its succession to Holders. The retiring Trustee shall 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 shall continue for the benefit of the retiring Trustee.

Section 7.09. Successor Trustee by Merger, Etc.

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

Section 7.10. Eligibility; Disqualification.

                  There shall at all times be a Trustee hereunder that is a
corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise
corporate trustee power, that is subject to supervision or examination by
federal or state authorities and that has a combined capital and surplus of at
least $150.0 million as set forth in its most recent published annual report of
condition.

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

Section 7.11. Preferential Collection of Claims Against Company.

                  The Trustee is subject to TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). A Trustee who has resigned
or been removed shall be subject to TIA Section 311(a) to the extent indicated
therein. The Trustee hereby waives any right to set-off any claim that it may
have against the Company in any capacity (other than as Trustee and Paying
Agent) against any of the assets of the Company held by the Trustee; provided,
however, that if the Trustee is or becomes a lender of any other Indebtedness
permitted hereunder to be pari passu with the Notes, then such waiver shall not
apply to the extent of such Indebtedness.

                       DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01. Option to Effect Legal Defeasance or Covenant Defeasance.

                  The Company may, at the option of the Board of Directors
evidenced by a 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 Eight.

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 shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to
have been discharged from its obligations with respect to all outstanding Notes
and all obligations of the Guarantors shall be deemed to have been discharged
with respect to their obligations under 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 shall
be deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes and Note Guarantees, respectively, which shall 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 (a) and (b) below, and to have
satisfied all its other obligations under such Notes and this Indenture (and the
Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following provisions which
shall survive until otherwise terminated or discharged hereunder: (a) the rights
of Holders of outstanding Notes to receive solely from the trust fund described
in Section 8.04 hereof, and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, interest and Liquidated Damages,
if any, on such Notes when such payments are due, (b) the Company's obligations
with respect to such Notes under Article 2 concerning issuing temporary Notes,
registration of Notes and mutilated, destroyed, lost or stolen Notes and the
Company's obligations under Section 4.02 hereof, (c) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and the Company's obligations in
connection therewith and (d) 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 shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be released
from its 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, 4.19 and 4.20 hereof with
respect to the outstanding Notes on and after the date the conditions set forth
in Section 8.04 are satisfied (hereinafter, "COVENANT DEFEASANCE"), and the
Notes shall thereafter be deemed not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes

                                       77

<PAGE>

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

Section 8.04. Conditions to Legal or Covenant Defeasance.

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

                  (i)      the Company must irrevocably deposit with the
         Trustee, in trust, for the benefit of the Holders of the Notes, cash in
         U.S. dollars, non-callable Government Securities, or a combination
         thereof, in such amounts as will be sufficient, in the opinion of a
         nationally recognized firm of independent public accountants, to pay
         the principal of, or interest and premium and Liquidated Damages, 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;

                  (ii)     in the case of Legal Defeasance, the Company shall
         have delivered to the Trustee an Opinion of Counsel reasonably
         acceptable to the Trustee confirming that (a) the Company has received
         from, or there has been published by, the Internal Revenue Service a
         ruling or (b) since the date of this Indenture, there has been a change
         in the applicable 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;

                  (iii)    in the case of Covenant Defeasance, the Company shall
         have delivered 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;

                  (iv)     no Default or Event of Default shall have occurred
         and be continuing either: (a) on the date of such deposit; or (b)
         insofar as Events of Default from bankruptcy

                                       78

<PAGE>

         or insolvency events are concerned, at any time in the period ending on
         the 91st day after the date of deposit;

                  (v)      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 to which the Company or any of its
         Subsidiaries is a party or by which the Company or any of its
         Subsidiaries is bound;

                  (vi)     the Company must have delivered to the Trustee an
         Opinion of Counsel to the effect that, (1) assuming no intervening
         bankruptcy of the Company or any Guarantor between the date of deposit
         and the 91st day following the deposit and assuming that no Holder is
         an "insider" of the Company under applicable bankruptcy law, after the
         91st day following the deposit, the trust funds will not be subject to
         the effect of Section 547 of the United States Bankruptcy Code and (2)
         the creation of the defeasance trust does not violate the Investment
         Company Act of 1940;

                  (vii)    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 of Notes over the other creditors
         of the Company with the intent of defeating, hindering, delaying or
         defrauding creditors of the Company or others;

                  (viii)   if the Notes are to be redeemed prior to their stated
         maturity, the Company must deliver to the Trustee irrevocable
         instructions to redeem all of the Notes on the specified redemption
         date; and

                  (ix)     the Company must deliver to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent 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.

                  (a)      Subject to Section 8.06 hereof, all money and
non-callable Government Securities (including the proceeds thereof) deposited
with the Trustee pursuant to Section 8.04 hereof in respect of the outstanding
Notes shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company 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, premium and Liquidated Damages, if
any, and interest, but such money need not be segregated from other funds except
to the extent required by law.

                  (b)      The Company shall 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.

<PAGE>

                  (c)      Anything in this Article Eight to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon the request of the Company any money or 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(a) 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 the Company.

                  Subject to applicable escheat laws, 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, premium, if any, or interest on any Note and
remaining unclaimed for two years after such principal, and premium, if any, or
interest has become due and payable shall be paid to the Company on its request
or (if then held by the Company) shall be discharged from such trust; and the
Holder of such Note shall thereafter look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, 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 shall not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money
then remaining shall 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 obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 8.02 or 8.03 hereof and, in the case of a Legal
Defeasance, the Guarantors' obligations under their respective Note Guarantees
shall be revised and reinstated as though no deposit had occurred pursuant to
Section 8.02 hereof, in each case 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 makes any
payment of principal of, premium, if any, or interest on any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent.

                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01. Without Consent of Holders of Notes.

                  (a)      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:

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

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

                  (iii)    to provide for the assumption of the Company's or any
         Guarantor's obligations to Holders of Notes in the case of a merger or
         consolidation or sale of all or substantially all of the Company's or
         such Guarantor's assets;

                  (iv)     to make any change that would provide any additional
         rights or benefits to the Holders of Notes or that does not adversely
         affect the legal rights under this Indenture of any such Holder;

                  (v)      to comply with requirements of the SEC in order to
         effect or maintain the qualification of this Indenture under the Trust
         Indenture Act;

                  (vi)     to provide for the issuance of Additional Notes in
         accordance with the limitations set forth in this Indenture as of its
         date;

                  (vii)    to allow any Guarantor to execute a supplemental
         Indenture and a Note Guarantee with respect to the Notes; or

                  (viii)   to evidence and provide for the acceptance of
         appointment of a successor Trustee.

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

Section 9.02. With Consent of Holders of Notes.

                  (a)      Except as otherwise provided in this Section 9.02,
the Company, the Guarantors and the Trustee may amend or supplement this
Indenture or the Notes with the consent of the Holders of at least a majority in
principal amount of the Notes then outstanding

                                       81

<PAGE>

(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes), and, subject to Sections 6.04
and 6.07 hereof, any existing Default or Event of Default or compliance with any
provision of this Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes).

                  (b)      The Company may, but shall not be obligated to, fix a
record date for the purpose of determining the Persons entitled to consent to
any indenture supplemental hereto. If a record date is fixed, the Holders on
such record date, or its duly designated proxies, and only such Persons, shall
be entitled to consent to such supplemental indenture, whether or not such
Holders remain Holders after such record date; provided that unless such consent
shall have become effective by virtue of the requisite percentage having been
obtained prior to the date which is 90 days after such record date, any such
consent previously given shall automatically and without further action by any
Holder be cancelled and of no further effect.

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

                  (d)      It shall 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.

                  (e)      After an amendment, supplement or waiver under this
Section becomes effective, the Company shall mail to the Holders of Notes
affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Company to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such
amendment, supplement or waiver. Subject to Sections 6.04 and 6.07 hereof, the
Holders of a majority in aggregate principal amount of the then outstanding
Notes (including Additional Notes, if any) may waive compliance in a particular
instance by the Company with any provision of this Indenture, or the Notes.
However, without the consent of each Holder affected, an amendment or waiver
under this Section 9.02 may not (with respect to any Notes held by a
non-consenting Holder):

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

                  (ii)     reduce the principal of or change the fixed maturity
         of any Note or alter the provisions, or waive any payment, with respect
         to the redemption of the Notes;

                                       82

<PAGE>

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

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

                  (v)      make any Note payable in money other than U.S.
         dollars;

                  (vi)     make any change in the provisions of this Indenture
         relating to waivers of past Defaults or the rights of Holders of Notes
         to receive payments of principal of, or interest or premium or
         Liquidated Damages, if any, on the Notes;

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

                  (viii)   impair the right to institute suit for the
         enforcement of any payment on or with respect to the Notes or the Note
         Guarantees;

                  (ix)     amend, change or modify the obligation of the Company
         to make and consummate an Asset Sale Offer with respect to any Asset
         Sale in accordance with Section 4.10 after the obligation to make such
         Asset Sale Offer has arisen or the obligation of the Company to make
         and consummate a Change of Control Offer in the event of a Change of
         Control in accordance with Section 4.14 after such Change of Control
         has occurred, including, in each case, amending, changing or modifying
         any definition relating thereto;

                  (x)      except as otherwise permitted under Section 5.01,
         consent to the assignment or transfer by the Company or any Guarantor
         of any of their rights or obligations under this Indenture; and

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

Section 9.03. Compliance with Trust Indenture Act.

                  Every amendment or supplement to this Indenture or the Notes
shall be set forth in a document 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 the Holder of a
Note and every subsequent Holder of a Note or portion of a Note that evidences
the same debt as the consenting Holder's Note, even if notation of the consent
is not made on any Note. However, any such Holder of a Note or subsequent Holder
of a Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective.

                                       83

<PAGE>

An amendment, supplement or waiver becomes effective in accordance with its
terms and thereafter binds every Holder.

Section 9.05. Notation on or Exchange of Notes.

                  (a)      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.

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

Section 9.06. Trustee to Sign Amendments, Etc.

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

                                  ARTICLE TEN
                                 NOTE GUARANTEES

Section 10.01. Guarantee.

                  (a)      Subject to this Article Ten, each of the Guarantors
hereby, jointly and severally, and fully and 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: (a) the principal of, premium, if any, and interest and
Liquidated Damages, 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, premium, if any, and interest and Liquidated Damages,
if any, on the Notes, if lawful (subject in all cases to any applicable grace
period provided herein), and all other obligations of the Company to the Holders
or the Trustee hereunder or thereunder will be promptly paid in full or
performed, all in accordance with the terms hereof and thereof; and (b) in case
of any extension of time of payment or renewal of any Notes or any of such other
obligations, the same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, 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 shall be jointly and severally obligated to pay the same immediately.
Each Guarantor agrees that this is a guarantee of payment and not a guarantee of
collection.

                                       84

<PAGE>

                  (b)      The Guarantors hereby agree that, to the maximum
extent permitted under applicable law, their obligations hereunder shall be
unconditional, irrespective of the validity, regularity or enforceability of the
Notes or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Notes 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. Subject to Section 6.06
hereof, 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 covenants that this Note Guarantee shall
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 any of the Company or
the Guarantors, any amount paid by any of them to the Trustee or such Holder,
this Note Guarantee, to the extent theretofore discharged, shall be reinstated
in full force and effect.

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

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 such Note Guarantee. To effectuate the foregoing intention,
the Trustee, the Holders and the Guarantors hereby irrevocably agree that the
obligations of such Guarantor will be limited to the maximum amount as will,
after giving effect to 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 Ten, result in the obligations of such Guarantor
under its Note Guarantee not constituting a fraudulent transfer or conveyance.

                                       85

Section 10.03. Execution and Delivery of Note Guarantee.

                  (a)      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 included in Exhibit E shall be endorsed by an Officer
of such Guarantor on each Note authenticated and delivered by the Trustee and
that this Indenture shall be executed on behalf of such Guarantor by its
President or one of its Vice Presidents.

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

                  (c)      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
shall be valid nevertheless.

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

                  (e)      If required by Section 4.20 hereof, the Company shall
cause such Subsidiaries to execute supplemental indentures to this Indenture and
Note Guarantees in accordance with Section 4.20 hereof and this Article Ten, to
the extent applicable.

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

                  (a)      A Guarantor 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:

                  (i)      immediately after giving effect to that 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 (if other than the Guarantor)
                  is a corporation or limited liability company organized or
                  existing under the laws of the United States, any state
                  thereof or the District of Columbia and assumes all the
                  obligations of that Guarantor under this Indenture, its Note
                  Guarantee and the Registration Rights Agreement pursuant to a
                  supplemental indenture reasonably satisfactory to the Trustee;
                  or

                           (B)      such sale or other disposition or
                  consolidation or merger complies with Section 4.10 hereof.

                  (b)      In case of any such consolidation, merger, sale or
conveyance governed by Section 10.04(a)(ii)(A), upon the assumption by the
successor Person, by supplemental

                                       86

<PAGE>

indenture, executed and delivered to the Trustee and reasonably satisfactory in
form to the Trustee, of the Note Guarantee endorsed upon the Notes and the due
and punctual performance of all of the covenants and conditions of this
Indenture to be performed by a Guarantor, such successor Person shall succeed to
and be substituted for a Guarantor with the same effect as if it had been named
herein as a Guarantor. Such successor Person thereupon may cause to be signed
any or all of the 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 shall 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.

Section 10.05. Release of Guarantor.

                  (a)      Any Guarantor will be released and relieved of any
obligations under its Note Guarantee, (i) in connection with any sale or other
disposition of all of the Capital Stock of that Guarantor to a Person that is
not (either before or after giving effect to such transaction) an Affiliate of

                  indebtedness on the Notes not delivered to the Trustee for

Certificate and an Opinion of Counsel (which opinion may be subject to customary
assumptions and exclusions) to the Trustee stating that all conditions precedent
to satisfaction and discharge have been satisfied.

                  (c)      Notwithstanding the above, the Trustee shall pay to
the Company from time to time upon its request any cash or Government Securities
held by it as provided in this section which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification delivered to the Trustee, are in excess of the amount thereof that
would then be required to be deposited to effect a satisfaction and discharge
under this Article Eleven.

               Other Miscellaneous Provisions.

                  Subject to Section 11.03 hereof, all money and non-callable

                  (a)      Any request, demand, authorization, direction,
notice, consent, waiver or other action provided by this Indenture to be given
or taken by the Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agents duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes

                                       92

<PAGE>

referred to as the "ACT" of the Holders signing such instrument or instruments.
Proof of execution of any such instrument or of a writing appointing any such
agent shall be sufficient for any purpose of this Indenture and conclusive in
favor of the Trustee and the Company if made in the manner provided in this
Section 12.14.

                  (b)      The fact and date of the execution by any Person of
any such instrument or writing may be proved by the affidavit of a witness of
such execution or by a certificate of a notary public or other officer
authorized by law to take acknowledgments of deeds, certifying that the
individual signing such instrument or writing acknowledged to such witness,
notary or officer the execution thereof. Where such execution is by a signer
acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of authority. The fact and date
of the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other manner which the
Trustee deems sufficient.

                  (c)      Notwithstanding anything to the contrary contained in
this Section 12.14, the principal amount and serial numbers of Notes held by any
Holder, and the date of holding the same, shall be proved by the register of the
Notes maintained by the Registrar as provided in Section 2.04 hereof.

                  (d)      If the Company shall solicit from the Holders of the
Notes any request, demand, authorization, direction, notice, consent, waiver or
other Act, the Company may, at its option, by or pursuant to a resolution of its
Board of Directors, fix in advance a record date for the determination of
Holders entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding TIA Section 316(c), such record date shall be the record date
specified in or pursuant to such resolution, which shall be a date not earlier
than the date 30 days prior to the first solicitation of Holders generally in
connection therewith or the date of the most recent list of Holders forwarded to
the Trustee prior to such solicitation pursuant to Section 2.06 hereof and not
later than the date such solicitation is completed. If such a record date is
fixed, such request, demand, authorization, direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders
of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of the then outstanding Notes have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other Act, and for that purpose the then outstanding Notes shall be computed as
of such record date; provided that no such authorization, agreement or consent
by the Holders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than
eleven months after the record date.

                  (e)      Any request, demand, authorization, direction,
notice, consent, waiver or other Act of the Holder of any Note shall bind every
future Holder of the same Note and the Holder of every Note issued upon the
registration or transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Note.

by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such principal amount.

implied, shall give to any Person, other than the parties hereto, any Paying
Agent, any Registrar and its successors hereunder, and the Holders, any benefit
or any legal or equitable right, remedy or claim under this Indenture.

                             [Reverse Side of Note]

                             TEXAS INDUSTRIES, INC.
                         10 1/4% Senior Notes due 2011

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

                  1.       Interest. The Company promises to pay interest on the
principal amount of this Note at 10 1/4% per annum from the date hereof until
maturity and shall pay the Liquidated Damages, if any, payable pursuant to
Section 5 of the Registration Rights Agreement referred to below. The Company
shall pay interest and Liquidated Damages, if any, semi-annually in arrears on
June 15 and December 15 of each year, or if any such day is not a Business Day,
on the next succeeding Business Day (each an "Interest Payment Date"). Interest
on the Notes shall accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from the date of original issuance;
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 December 15, 2003. The Company shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal and premium, if any, from time to time on demand at a rate
that is 1% per annum in excess of the rate then in effect; it shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue installments of interest and Liquidated Damages (without regard to any
applicable grace periods) from time to time on demand at the same rate to the
extent lawful. Interest shall be computed on the basis of a 360-day year of
twelve 30-day months.

                  2.       Method of Payment. The Company shall pay interest on
the Notes (except defaulted interest) and Liquidated Damages, if any, to the
Persons who are registered Holders of Notes at the close of business on the
record date immediately 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 2.13 of the Indenture with respect to defaulted
interest. The Notes shall be payable as to principal, premium and Liquidated
Damages, if any, and interest at the office or agency of the Company maintained
for such purpose in The City of New York, or, at the option of the Company,
payment of interest and Liquidated Damages, if any, may be made by check mailed
to the Holders at their addresses set forth in the register of Holders, and
provided that payment by wire transfer of immediately available funds shall be
required with respect to principal of and interest, premium and Liquidated
Damages, if any, on, all Global Notes and to any Holder of $1.0 million or more
of Notes which shall have provided wire transfer instructions to the Company or
the Paying Agent. Such payment shall be in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts.

                  3.       Paying Agent and Registrar. Initially, the Trustee
under the Indenture shall act as Paying Agent and Registrar. The Company may
change any Paying Agent or

                                      A1-4

<PAGE>

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

                  4.       Indenture. The Company issued the Notes under an
Indenture dated as of June 6, 2003 ("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 Notes are subject to all such terms, and
Holders are referred to the Indenture and such Act 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 Indenture pursuant to which this Note is issued provides that
an unlimited aggregate principal amount of Additional Notes may be issued
thereunder.

                  5.       Optional Redemption. (a) Except as set forth in
paragraph 5(b) below, the Company shall not have the option to redeem any Notes
prior to June 15, 2007. Thereafter, the Company shall have the option to redeem
the Notes, in whole or in part, upon not less than 30 nor more than 60 days'
prior notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest and Liquidated Damages,
if any, thereon to the applicable redemption date, if redeemed during the
twelve-month period beginning on June 15, of the years indicated below (subject
to the right of Holders on the relevant record date to receive interest due on
the related interest payment date):

<TABLE>
<CAPTION>
       Year                                    Percentage
       ----                                    ----------
<S>                                            <C>

2008...................................         102.563%
2009 and thereafter....................         100.000%
</TABLE>

                  (b)      Notwithstanding the foregoing, at any time prior to
June 15, 2006, the Company may redeem up to 35% of the aggregate principal
amount of Notes originally issued under the Indenture at a redemption price of
110.250% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, to the redemption date, with the net cash proceeds
of one or more Equity Offerings of the Company; provided that (A) at least 65%
of the aggregate principal amount of the Notes originally issued under the
Indenture remains outstanding immediately after the occurrence of such
redemption, excluding Notes held by the Company and its Subsidiaries; and (B)
the redemption must occur within 45 days of the date of the closing of such
Equity Offering.

                  (c)      In addition, at any time prior to June 15, 2007, the
Company may redeem all or part of the Notes upon not less than 30 days nor more
than 60 days' notice at a redemption price equal to the sum of (i) the principal
amount thereof, plus (ii) accrued and unpaid interest, if any, to the applicable
date of redemption, plus (iii) the Make-Whole Premium.

                  6.       Repurchase at Option of Holder. (a) If a Change of
Control occurs, each Holder of Notes will have the right to require the Company
to repurchase all or any part (equal to $1,000 or an integral multiple thereof)
of such Holder's Notes pursuant to an offer by the Company (a "Change of Control
Offer") at an offer price (a "Change of Control Payment") in cash equal to 101%
of the aggregate principal amount thereof plus accrued and unpaid interest

                                      A1-5

<PAGE>

and Liquidated Damages, if any, thereon to the date of purchase. Within ten 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 offering to repurchase Notes on a date (the "Change of Control Payment
Date") specified in such notice, which shall be no earlier than 30 days and no
later than 60 days from the date such notice is mailed, pursuant to the
procedures required by the Indenture and described in such notice.

                  (b)      Within 360 days after the receipt of any Net Proceeds
from an Asset Sale, the Company may apply such Net Proceeds at its option: (i)
to repay Indebtedness under the Credit Facilities or Unsubordinated Indebtedness
secured by such assets and, if the Indebtedness repaid is revolving credit
Indebtedness, to correspondingly reduce commitments with respect thereto; or
(ii) to purchase Replacement Assets or make a capital expenditure in or that is
used or useful in a Permitted Business. Pending the final applications 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 the Indenture. Any Net Proceeds from Asset Sales that are not
applied or invested as provided in the next preceding sentence will constitute
"Excess Proceeds." Within ten days after the aggregate amount of Excess Proceeds
exceeds $10.0 million, the Company shall make an offer (an "Asset Sale Offer")
to all Holders of Notes and all holders of other Unsubordinated Indebtedness
containing provisions similar to those set forth in the Indenture with respect
to offers to purchase with the proceeds of sales of assets, to purchase the
maximum principal amount of Notes and such other Unsubordinated Indebtedness
that may be purchased out of the Excess Proceeds. The offer price in any Asset
Sale Offer shall be equal to 100% of the principal amount thereof plus accrued
and unpaid interest and Liquidated Damages, if any, to the date of purchase and
shall 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 the Indenture. If the aggregate principal amount of
Notes and such other Unsubordinated Indebtedness tendered into such Asset Sale
Offer exceeds the amount of Excess Proceeds, Notes and such other Unsubordinated
Indebtedness to be purchased shall be selected on a pro rata basis based on the
principal amount of Notes and such other Unsubordinated Indebtedness tendered.
Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be
reset at zero.

                  7.       Denominations, Transfer, Exchange. The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company is not required
to transfer or exchange any Note selected for redemption. Also, the Company is
not required to transfer or exchange any Note for a period of 15 days before a
selection of Notes to be redeemed. Transfer may be restricted as provided in the
Indenture.

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

                  9.       Amendment, Supplement and Waiver. Subject to certain
exceptions, the Indenture or the Notes may be amended or supplemented with the
consent of the Holders of at

                                      A1-6

<PAGE>

least a majority in principal amount of the then outstanding Notes (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, the Notes), and any existing default or
compliance with any provision of the Indenture or the Notes may be waived with
the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, the
Notes). Without the consent of any Holder of a Note, the Indenture or the Notes
may be amended or supplemented to, among other things, cure any ambiguity,
defect or inconsistency, or to make any change that does not adversely affect
the legal rights under the Indenture of any such Holder.

                  10.      Defaults and Remedies. In the case of an Event of
Default arising from certain events of bankruptcy or insolvency, with respect to
the Company or any Significant Subsidiary of the Company (or any Restricted
Subsidiaries that together would constitute a Significant Subsidiary), 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
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 immediately by notice in writing
to the Company specifying the Event of Default. Holders of the Notes 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 Default or
Event of Default (except a Default or Event of Default relating to the payment
of principal, premium, interest or Liquidated Damages) if it determines that
withholding notice is in their interest. Holders of a majority in principal
amount of the then outstanding Notes by notice to the Trustee may, on behalf of
the Holders of all of the Notes, rescind and annul a declaration of acceleration
pursuant to Section 6.02 hereof, and its consequences, and waive any related
existing Default or Event of Default if certain conditions are satisfied.

                  With respect to periods after June 15, 2007, in the case of
any Event of Default occurring 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(a) of the
Indenture, an equivalent premium shall also become and be immediately due and
payable to the extent permitted by law upon the acceleration of the Notes. With
respect to periods prior to June 15, 2007, if an Event of Default occurs during
any time that the Notes are outstanding, 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(c) of the
Indenture, then the premium specified in Section 3.07(c) of the Indenture as
being payable upon an optional redemption prior to June 15, 2007 shall become
immediately due and payable to the extent permitted by law upon the acceleration
of the Notes.

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

                                      A1-7

<PAGE>

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

                  13.      Authentication. This Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

                  14.      Additional Rights of Holders of Restricted Global
Notes and Restricted Definitive Notes. In addition to the rights provided to
Holders under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of June 6, 2003, between the Company, the Guarantors and the
parties named on the signature pages thereof or, in the case of Additional
Notes, Holders of Restricted Global Notes and Restricted Definitive Notes shall
have the rights set forth in one or more registration rights agreements, if any,
between the Company, the Guarantors and the other parties thereto, relating to
rights given by the Company and the Guarantors to the purchasers of Additional
Notes (the "Registration Rights Agreement").

                  15.      CUSIP Numbers. Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures, the
Company has caused CUSIP numbers to be printed on the Notes and the Trustee 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.

                  16.      Guarantee. The Company's obligations under the Notes
are fully and unconditionally guaranteed, jointly and severally, by the
Guarantors.

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

the principal amount at maturity of $___________ in such Note[s] or interests
(the "Transfer"), to ___________________________ (the "Transferee"), as further

         [ ]      1.       Check if Transferee will take delivery of a

Rule 144A. The Transfer is being effected pursuant to and in accordance with
Rule 144A under the United States Securities Act of 1933, as amended (the

Act) and have such knowledge and experience in financial and business matters as
to be capable of evaluating the merits and risks of our investment in the Notes,
and we and any accounts for which we are acting are each able to bear the
economic risk of our or its investment.

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

                  2.  Agreement to Guarantee.

         (a)      The Guaranteeing Subsidiary, along with all other Guarantors,
jointly and severally, and fully and 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 the
Indenture, the Notes or the obligations of the Company hereunder or thereunder,
that:

                  (i)      the principal of, premium, if any, and interest and
Liquidated Damages, 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, premium, if any, and interest and Liquidated Damages,
if any, on the Notes, if lawful (subject in all cases to any applicable grace
period provided herein), and all other obligations of the Company to the Holders
or the Trustee hereunder or thereunder will be promptly paid in full or
performed, all in

                                       F-1

<PAGE>

accordance with the terms hereof and thereof; and the principal of, premium, if
any, and interest and Liquidated Damages, 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, premium, if any, and
interest and Liquidated Damages, if any, on the Notes, if lawful (subject in all
cases to any applicable grace period provided herein)

                  (ii)     in case of any extension of time of payment or
renewal of any Notes or any of such other obligations, the same will be promptly
paid in full when due or performed in accordance with the terms of the extension
or renewal, 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 shall be jointly and severally obligated to
pay the same immediately. The Guaranteeing Subsidiary agrees that this is a
guarantee of payment and not a guarantee of collection.

         (b)      The Guaranteeing Subsidiary hereby agrees that, to the maximum
extent permitted under applicable law, its obligations hereunder shall be
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 of the Notes 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 that might otherwise constitute a
legal or equitable discharge or defense of a Guarantor.

         (c)      The Guaranteeing Subsidiary, subject to Section 6.06 of the
Indenture, hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of insolvency or bankruptcy of the Company, any
right to require a proceeding first against the Company, protest, notice and all
demands whatsoever and covenants that this Note Guarantee shall not be
discharged except by complete performance of the obligations contained in the
Notes and the Indenture.

         (d)      The Guaranteeing Subsidiary agrees that 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 any of the Company or the Guarantors, any amount paid by
any of them to the Trustee or such Holder, this Note Guarantee, to the extent
theretofore discharged, shall be reinstated in full force and effect.

         (e)      The Guaranteeing Subsidiary agrees that the Guaranteeing
Subsidiary shall not be entitled to any right of subrogation in relation to the
Holders in respect of any obligations guaranteed hereby until payment in full of
all obligations guaranteed hereby.

         (f)      The Guaranteeing Subsidiary agrees that, as between the
Guarantors, on the one hand, and the Holders and the Trustee, on the other hand,
(x) the maturity of the obligations guaranteed hereby may be accelerated as
provided in Article Six 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 (y) in
the event of any declaration of acceleration of such obligations as provided in
Article Six of the Indenture, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Guarantors for the purpose of this
Note Guarantee.

                                       F-2

<PAGE>

         (g)      The Guaranteeing Subsidiary shall have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right
does not impair the rights of Holders under the Note Guarantee.

         (h)      The Guaranteeing Subsidiary confirms, pursuant to Section
10.02 of the Indenture, that it is the intention of such Guaranteeing Subsidiary
that its Note Guarantee 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 its Note Guarantee and, to effectuate the foregoing intention,
agrees hereby irrevocably that the obligations of such Guaranteeing Subsidiary
will be limited to the maximum amount as will, after giving effect to all other
contingent and fixed liabilities of such Guaranteeing Subsidiary 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
Article Ten of the Indenture, result in the obligations of such Guaranteeing
Subsidiary under its Note Guarantee not constituting a fraudulent transfer or
conveyance.

                  3.  Execution and Delivery.  The Guaranteeing Subsidiary
agrees that the Note Guarantees 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)      A Guarantor may not sell or otherwise dispose of all
or substantially all of its assets, 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:

                  (i)      immediately after giving effect to that 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 (if other than the Guarantor)
                  is a corporation or limited liability company organized or
                  existing under the laws of the United States, any state
                  thereof or the District of Columbia and assumes all the
                  obligations of that Guarantor under the Indenture, its Note
                  Guarantee and the Registration Rights Agreement pursuant to a
                  supplemental indenture reasonably satisfactory to the Trustee;
                  or

                           (B)      such sale or other disposition or
                  consolidation or merger complies with Section 4.10 of the
                  Indenture.

                  (b)      In case of any such consolidation, merger, sale or
conveyance governed by Section 4(a) hereof and upon the assumption by the
successor Person, by supplemental indenture, executed and delivered to the
Trustee and reasonably satisfactory in form to the Trustee, of the Note
Guarantee endorsed upon the Notes and the due and punctual performance

                                       F-3

<PAGE>

of all of the covenants and conditions of the Indenture to be performed by a
Guarantor, such successor Person shall succeed to and be substituted for a
Guarantor with the same effect as if it had been named herein as a Guarantor.
Such successor Person thereupon may cause to be signed any or all of the 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 shall 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 hereof.

                  5.  Release.

                  (a)      Any Guarantor will be released and relieved of any
obligations under its Note Guarantee, (i) in connection with any sale or other
disposition of all of the Capital Stock of that Guarantor to a Person that is
not (either before or after giving effect to such transaction) an Affiliate of
the Company, if the sale of all such Capital Stock of that Guarantor complies
with Section 4.10 of the Indenture; (ii) if the Company properly designates that
Guarantor as an Unrestricted Subsidiary under the Indenture or (iii) upon the
release or discharge of the Guarantee which resulted in the creation of such
Note Guarantee pursuant to Section 4.18(b) of the Indenture, except a discharge
or release by or as a result or payment under such Guarantee. Upon delivery by
the Company to the Trustee of an Officers' Certificate and an Opinion of Counsel
to the effect that one of the foregoing requirements has been satisfied and the
conditions to the release of a Guarantor under this Section 5 have been
satisfied, the Trustee shall execute any documents reasonably required in order
to evidence the release of such Guarantor from its obligations under its Note
Guarantee.

                  (b)      Any Guarantor not released from its obligations under
its Note Guarantee shall remain liable for the full amount of principal of and
interest and Liquidated Damages, if any, on the Notes and for the other
obligations of any Guarantor under the Indenture as provided in Article Ten of
the Indenture.

                  6.  No Recourse Against Others. Pursuant to Section 12.07 of
the Indenture, no director, officer, employee, incorporator or stockholder of
the Guaranteeing Subsidiary shall have any liability for any obligations of such
Guaranteeing Subsidiary under the Notes, the Indenture, the Note Guarantees or
for any claim based on, in respect of, or by reason of, such obligations or
their creation.

                  7.  NEW YORK LAW TO GOVERN. THE LAW OF THE STATE OF NEW YORK
