Investment, disposition, merger, consolidation or discontinued operation, in
each case with respect to an operating unit of a business, that would have

consolidation had occurred at the beginning of the applicable four-quarter
reference period. Any Person that is not a Restricted Subsidiary on the
Calculation Date will be deemed not to have been a Restricted Subsidiary at any
time during such four-quarter period.

            For purposes of this definition, whenever pro forma effect is to be
given to any transaction, the pro forma calculations shall be made in good faith
by a responsible financial or accounting officer of the Company. If any
Indebtedness bears a floating rate of interest and is being given pro forma
effect, the interest on such Indebtedness shall be calculated as if the rate in
effect on the Calculation Date had been the applicable rate for the entire
period (taking into account any Hedging Obligations applicable to such
Indebtedness if such Hedging Obligation has a remaining term in excess of 12
months). Interest on a Capital Lease Obligation shall be deemed to accrue at an
interest rate reasonably determined by a responsible financial or accounting
officer of the Company to be the rate of interest implicit in such Capital Lease
Obligation in accordance with GAAP. For purposes of making the computation
referred to above, interest on any Indebtedness under a revolving credit
facility computed on a pro forma basis shall be computed based upon the average
daily balance of such Indebtedness during the applicable period. Interest on
Indebtedness that may optionally be determined at an interest rate based upon a
factor of a prime or similar rate, a eurocurrency interbank offered rate, or
other rate, shall be deemed to have been based upon the rate actually chosen,
or, if none, then based upon such optional rate chosen as the Company may
designate. Any such pro forma calculation may include adjustments appropriate,
in the reasonable determination of the Company as set forth in an Officers'
Certificate, to reflect operating expense reductions reasonably expected to
result from any acquisition or merger.

      component of all payments associated with Capital Lease Obligations and
      net of the effect of all payments made or received pursuant to Hedging
      Obligations in respect of interest rates; plus

            (2) the consolidated interest expense of such Person and its
      Restricted Subsidiaries that was capitalized during such period; plus

endorsements required by law, stock exchange rule or usage. Each Note will be
dated the date of its authentication. The Notes shall be in denominations of
$1,000 and integral multiples thereof.

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

            (c) 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 Section 2.06 and 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.

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

Section 2.02 Execution and Authentication.

            At least one Officer must 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 will nevertheless be valid.

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

            The Trustee will, upon receipt of a written order of the Company
signed by two Officers of the Company (an "Authentication Order"), authenticate
Notes for original issue that may be validly issued under this Indenture,
including any Additional Notes and any Exchange Notes. The aggregate principal
amount of Notes outstanding at any time may not exceed the aggregate principal
amount of Notes authorized for issuance by the Company pursuant to one or more
Authentication Orders, except as provided in Section 2.07 hereof.

            The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

Section 2.03 Registrar and Paying Agent.

            The Company will maintain an office or agency where Notes may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Notes may be presented for payment ("Paying Agent"). The
Registrar will keep a register of the Notes and of their transfer and exchange.
The Company may appoint one or more co-registrars and one or more additional
paying agents. The term "Registrar" includes any co-registrar and the term
"Paying Agent" includes any additional paying agent. The Company may change any
Paying Agent or Registrar without notice to any Holder. The Company will notify
the Trustee in writing of the name and address of any Agent not a party to this
Indenture. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any of
its Subsidiaries may act as Paying Agent or Registrar.

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

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

Section 2.04 Paying Agent to Hold Money in Trust.

            The Company will require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all

                                      -37-

<PAGE>

money held by the Paying Agent for the payment of principal, premium or
Additional Interest, if any, or interest on the Notes, and will notify the
Trustee of any default by the Company in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held
by it to the Trustee. The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary) will have no further
liability for the money. If the Company or a Subsidiary acts as Paying Agent, it
will segregate and hold in a separate trust fund for the benefit of the Holders
all money held by it as Paying Agent. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee will serve as Paying Agent for
the Notes.

Section 2.05 Holder Lists.

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

Section 2.06 Transfer and Exchange.

            (a) Transfer and Exchange of Global Notes. A Global Note may not be
transferred except as a whole 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 will be exchanged by
the Company for Definitive Notes if:

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

            (2) 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 and the receipt by the Registrar of any certificates required
      pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or

            (3) there shall have occurred and be continuing an Event of Default
      with respect to the Notes.

            Upon the occurrence of either of the preceding events in (1) or (2)
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

                                      -38-

2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or
in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06
or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form
of, and shall be, a Global Note. A Global Note may not be exchanged for another
Note other than as provided in this Section 2.06(a), however, beneficial
interests in a Global Note may be transferred and exchanged as provided in
Section 2.06(b), (c) or (f) hereof.

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

            (1) Transfer of Beneficial Interests in the Same Global Note.

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

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

                        (ii) instructions given by the Depositary to the
                  Registrar containing information regarding the Person in whose

                  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 and the receipt by the Registrar of any
                  certificates required pursuant to Rule 903 under the
                  Securities Act.

      Upon consummation of a Registered Exchange Offer by the Company in
      accordance with Section 2.06(f) hereof, the requirements of this Section
      2.06(b)(2) shall be deemed to have been satisfied upon receipt by the
      Registrar of the instructions contained in the Letter of Transmittal
      delivered by the Holder of such beneficial interests in the Restricted

      Note(s) pursuant to Section 2.06(h) hereof.

            (3) Transfer of Beneficial Interests to Another Restricted Global
      Note. A beneficial interest in any Restricted Global Note may be
      transferred to a Person who takes delivery thereof in the form of a
      beneficial interest in another Restricted Global Note if the transfer
      complies with the requirements of Section 2.06(b)(2) above and the
      Registrar receives the following:

      record date and the next succeeding interest payment date.

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

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

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

Section 2.07 Replacement Notes.

            If any mutilated Note is surrendered to the Trustee or the Company
and the Trustee receives evidence to its satisfaction of the destruction, loss
or theft of any Note, the Company will issue and the Trustee, upon receipt of an
Authentication Order, will authenticate a replacement Note if the Trustee's
requirements are met. If required by the Trustee or the Company, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any

                                      -52-

<PAGE>

authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Company may charge for their expenses in replacing a Note.

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

Section 2.08 Outstanding Notes.

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

            If a Note is replaced pursuant to Section 2.07 hereof, it ceases to
be outstanding unless the Trustee and the Registrar receive proof satisfactory
to it that the replaced Note is held by a protected purchaser.

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

            If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay all principal, premium and accrued interest with respect to
the outstanding Notes payable on that date and is not prohibited from paying
such money to the Holders thereof pursuant to the terms of Section 10 hereof,
then on and after that date such Notes will be deemed to be no longer
outstanding and will cease to accrue interest.

Section 2.09 Treasury Notes.

            In determining whether the Holders of the required principal amount
of Notes have concurred in any direction, request, waiver or consent in the
exercise of any discretion, power or authority (whether contained in this
Indenture or vested by operation of law) which the Trustee is required,
expressly or impliedly, to exercise in or by reference to the interests of the
Holders or any of them, Notes owned by the Company or any Guarantor, or by any
Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company or any Guarantor, will be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee will be protected in relying on any such direction, waiver or consent,
only Notes that a Responsible Officer of the Trustee knows are so owned will be
so disregarded.

Section 2.10 Temporary Notes.

            Until certificates representing Notes are ready for delivery, the
Company may prepare and the Trustee, upon receipt of an Authentication Order,
will authenticate temporary

                                      -53-

<PAGE>

Notes. Temporary Notes will be substantially in the form of certificated Notes
but may have variations that the Company considers appropriate for temporary
Notes and as may be reasonably acceptable to the Trustee. Without unreasonable
delay, the Company will prepare and the Trustee will authenticate definitive
Notes in exchange for temporary Notes.

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

Section 2.11 Cancellation.

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

Section 2.12 Defaulted Interest.

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

Section 2.13 CUSIP Numbers.

            The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on
the Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Trustee in
writing 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 must furnish to the Trustee, at
least 30 days but not more than 60 days before a redemption date, an Officers'

      have been satisfied.

Section 3.02 Selection of Notes to Be Redeemed.

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

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

            (2) if the Notes are not listed on any national securities exchange,
      on a pro rata basis.

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

            The Trustee will promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption or purchase, the principal amount thereof to be redeemed. Notes and
portions of Notes selected will be in amounts of $1,000 or whole multiples of
$1,000; provided that no Notes of $1,000 or less shall be redeemed in part.
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 will mail or cause to be mailed, by first class mail, a notice
of redemption to the Trustee and each Holder whose Notes are to be redeemed at
its registered address, except that redemption notices may be mailed more than
60 days prior to a redemption date if the notice is issued in connection with a
defeasance of the Notes or a satisfaction and discharge of this Indenture
pursuant to Articles 8 or 12 hereof.

            The notice will identify the Notes (including CUSIP Numbers) to be
redeemed and will state:

            (1) the redemption date;

            (2) the redemption price;

            (3) if any Note is being redeemed in part, the portion of the
      principal amount of such Note to be redeemed and that, after the
      redemption date upon surrender of such Note, a new Note or Notes in
      principal amount equal to the unredeemed portion will be issued upon
      cancellation of the original Note or with respect to a Global Note a
      notation shall be made on Schedule A thereto to reduce the principal
      amount of the Global Note to an amount equal to the unredeemed portion of
      the Global Note surrendered;

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

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

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

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

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

            At the Company's request, the Trustee will give the notice of
redemption in the Company's name and at their expense; provided, however, that
the Company has 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.

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.

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

            If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest will cease to accrue on
the Notes or the portions of Notes called for redemption. If a Note is redeemed
on or after an interest record date but on or prior to the related interest
payment date, then any accrued and unpaid interest shall be paid to the Person
in whose name such Note was registered at the close of business on such record
date. If any Note called for redemption is not 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 will

principal amount to the unredeemed or unpurchased portion of the Note
surrendered.

change in the location of any such other office or agency.

time of and after giving effect to such Restricted Payment:

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

            (B) the Company would, after giving pro forma effect to such
      Restricted Payment as if such Restricted Payment had been made at the
      beginning of the applicable four-quarter period, have been permitted to

or such Disqualified Stock or such preferred equity is issued, as the case may
be, would have been at least 2.0 to 1.0, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred or the Disqualified Stock or the
preferred equity had been issued, as the case may be, at the beginning of such
four-quarter period.

      and any Restricted Subsidiaries thereunder) not to exceed $895 million;

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

      or other Indebtedness or preferred stock, or synthetic lease obligations,
      in each case, incurred for the purpose of financing all or any part of the
      purchase price or cost of design, development, construction, installation
      or improvement of property (real or personal and including Capital Stock),
      plant or equipment used in the business of the Company or any of its
      Restricted Subsidiaries (in each case, whether through the direct purchase
      of such assets or the Equity Interests of any Person owning such assets),
      in an aggregate principal amount not to exceed, immediately after giving
      effect to any such incurrence, the greater of (x) $70.0 million and (y)
      5.0% of Total Assets;

            (5) the incurrence by the Company or any of its Restricted
      Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
      net proceeds of which are used to renew, refund, refinance, replace,
      defease or discharge any Indebtedness (other than intercompany
      Indebtedness) that was permitted by this Indenture to be incurred under
      Section 4.09(a) hereof or clause (2), (3), (4), (5), (12), (15) or (16) of
      this Section 4.09(b);

            (6) the incurrence by the Company or any of its Restricted
      Subsidiaries of intercompany Indebtedness between or among the Company and

            Indebtedness and the payee is not the Company or a Guarantor, such
            Indebtedness must be expressly subordinated to the prior payment in
            full in cash of all Obligations then due with respect to the notes,
            in the case of the Company, or the Note Guarantee, in the case of a
            Guarantor; and

                  (B) (i) any subsequent issuance or transfer of Equity

            Company, and (ii) any sale or other transfer of any such
            Indebtedness to a Person that is not either the Company or a
            Restricted Subsidiary of the Company, shall be deemed, in each case,
            to constitute an incurrence of such Indebtedness by the Company or
            such Restricted Subsidiary, as the case may be, that was not
            permitted by this clause (6);

            (7) the issuance by any of the Company's Restricted Subsidiaries to

            that results in any such preferred equity or Disqualified Stock
            being held by a Person other than the Company or a Restricted
            Subsidiary of the Company, and

                  (B) any sale or other transfer of any such preferred equity or
            Disqualified Stock to a Person that is not either the Company or a
            Restricted Subsidiary of the Company,

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

            (8) the incurrence by the Company or any of its Restricted
      Subsidiaries of Hedging Obligations other than for speculative purposes;

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

            (10) the incurrence by the Company or any of its Restricted
      Subsidiaries of Indebtedness in respect of workers' compensation claims,
      payment obligations in connection with health or other types of social
      security benefits, unemployment or other insurance or self-insurance
      obligations, reclamation, statutory obligations, bankers' acceptances,
      performance, surety or similar bonds and letters of credit or completion
      or performance guarantees or equipment leases (including, without
      limitation, performance guarantees and reimbursement obligations arising
      under or in accordance with the terms of the Purchase Agreement), or other
      similar obligations in the ordinary course of business or consistent with
      past practice;

            (11) the incurrence by the Company or any of its Restricted
      Subsidiaries of Indebtedness arising from the honoring by a bank or other
      financial institution of a check, draft or similar instrument
      inadvertently drawn against insufficient funds;

            (12) Indebtedness, Disqualified Stock or preferred equity of Persons
      that are acquired by the Company or any of its Restricted Subsidiaries or
      merged into a Restricted Subsidiary in accordance with the terms of this
      Indenture; provided, however, that such Indebtedness, or Disqualified
      Stock or preferred equity is not incurred or issued in contemplation of
      such acquisition or merger or to provide all or a portion of the funds or
      credit support required to consummate such acquisition or merger; provided
      further, however, that, for any such Indebtedness, Disqualified Stock or
      preferred equity outstanding under this clause (12) in excess of $10.0
      million on the date such Person is acquired by the Company or a Restricted

                  (A) the Company would be permitted to incur at least $1.00 of
            additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
            test set forth in the first sentence of this Section 4.09; or

                                      -70-

<PAGE>

                  (B) the Fixed Charge Coverage Ratio, on the date of and after
            giving pro forma effect to such acquisition and such incurrence or
            issuance, would not be reduced as a result of such acquisition;

            (13) Indebtedness incurred by a Receivables Subsidiary in a

      acquisition of any business, assets or a Subsidiary in accordance with the
      terms of this Indenture, other than guarantees of Indebtedness incurred or
      assumed by any Person acquiring all or any portion of such business,
      assets or Subsidiary for the purpose of financing such acquisition;

            (15) the incurrence by the Company or any of its Restricted
      Subsidiaries of additional Indebtedness or the issuance of Disqualified
      Stock or preferred equity in an aggregate principal amount (or accreted
      value, as applicable) or having an aggregate liquidation preference at any
      time outstanding not to exceed $85.0 million (it being understood that any
      Indebtedness, Disqualified Stock or preferred equity incurred pursuant to
      this clause (15) shall cease to be deemed incurred or outstanding for
      purposes of this Section 4.09 from and after the date on which the Company
      could have incurred such Indebtedness or Disqualified Stock or preferred
      equity under Section 4.09(a) hereof without reliance upon this clause
      (15));

            (16) the incurrence by the Company or any of its Restricted
      Subsidiaries of additional Indebtedness arising out of advances on
      exports, advances on imports, advances on trade receivables, factoring of
      receivables, customer prepayments and similar transactions in the ordinary
      course of business and consistent with past practice;

            (17) the incurrence of additional Indebtedness by a Foreign
      Subsidiary in an aggregate principal amount which does not exceed the
      greater of (a) $50 million or (b) 3.5% of the Total Assets at any one time
      outstanding (which amount may, but need not, be incurred in whole or in
      part under a Credit Facility);

            (18) Indebtedness of the Company or any of its Restricted
      Subsidiaries in respect of the Management Notes; and

            (19) Contribution Indebtedness.

            For purposes of determining compliance with this Section 4.09, in
the event that an item of proposed Indebtedness, Disqualified Stock or preferred
equity meets the criteria of more than one of the categories of Permitted Debt
described in clauses (1) through (19) above or is entitled to be incurred
pursuant to Section 4.09(a) hereof, the Company will be permitted to classify
such item of Indebtedness, Disqualified Stock or preferred equity on the date of
its incurrence and will only be required to include the amount and type of such
Indebtedness,

                                      -71-

<PAGE>

Disqualified Stock or preferred equity in one of the above clauses, although the
Company may divide and classify an item of Indebtedness, Disqualified Stock or
preferred equity in one or more of the types of Indebtedness, Disqualified Stock
or preferred equity and may later reclassify all or a portion of such item of
Indebtedness, Disqualified Stock or preferred equity, in any manner that
complies with this Section 4.09. The accrual of interest or dividends, the
accretion or amortization of original issue discount, the payment of interest on
any Indebtedness in the form of additional Indebtedness with the same terms, the
reclassification of preferred equity as Indebtedness due to a change in
accounting principles, and the payment of dividends on Disqualified Stock or
preferred equity in the form of additional shares of the same class of
Disqualified Stock or preferred equity will not be deemed to be an incurrence of
Indebtedness or an issuance of Disqualified Stock or preferred equity for
purposes of this Section 4.09; provided, in each such case (other than preferred
stock that is not Disqualified Stock), that the amount of any such accrual,
accretion or payment is included in Fixed Charges of the Company as accrued.
Notwithstanding any other provision of this Section 4.09, the maximum amount of
Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to
this Section 4.09 shall not be deemed to be exceeded solely as a result of
fluctuations in exchange rates or currency values.

            The amount of any Indebtedness outstanding as of any date will be:

            (1) the accreted value of the Indebtedness, in the case of any
      Indebtedness issued with original issue discount;

            (2) the principal amount of the Indebtedness, in the case of any
      other Indebtedness; and

            (3) in respect of Indebtedness of another Person secured by a Lien
      on the assets of the specified Person, the lesser of:

                  (A) the Fair Market Value of such assets at the date of
            determination; and

                  (B) the amount of the Indebtedness of the other Person.

Section 4.10 Asset Sales.

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

            (1) The Company (or the Restricted Subsidiary, as the case may be)
      receives consideration at the time of the Asset Sale at least equal to the
      Fair Market Value of the assets or Equity Interests issued or sold or
      otherwise disposed of; and

            (2) at least 75% of the consideration received in the Asset Sale by
      the Company or such Restricted Subsidiary is in the form of cash, Cash
      Equivalents or Marketable Securities. For purposes of this provision, each
      of the following shall be deemed to be cash:

                                      -72-

<PAGE>

                  (A) any liabilities of the Company or any Restricted
            Subsidiary of the Company (other than contingent liabilities and
            liabilities that are by their terms subordinated to the Notes or any
            Note Guarantee) that are assumed by the transferee of any such
            assets and as a result of which, the Company or such Restricted
            Subsidiary of the Company are released from any further liability in
            connection therewith;

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

                  (C) any Designated Non-cash Consideration received by the
            Company or any of its Restricted Subsidiaries in such Asset Sale;
            provided that the aggregate Fair Market Value of such Designated
            Non-cash Consideration, taken together with the Fair Market Value at
            the time of receipt of all other Designated Non-cash Consideration
            received pursuant to this clause (C) less the amount of Net Proceeds
            previously realized in cash from prior Designated Non-cash
            Consideration is less than the greater of (x) 2.50% of Total Assets
            at the time of the receipt of such Designated Non-cash Consideration
            (with the Fair Market Value of each item of Designated Non-cash
            Consideration being measured at the time received and without giving
            effect to subsequent changes in value) and (y) $35.0 million; and

                  (D) any Capital Stock or assets of the kind referred to in
            clause (2) or (4) of the next paragraph of this Section 4.10.

            Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company (or the applicable Restricted Subsidiary, as the case may be)
may:

            (a) apply such Net Proceeds, at its option:

                  (1) to repay (w) Indebtedness and other Obligations
            constituting Senior Indebtedness, (x) any Indebtedness that was
            secured by the assets sold in such Asset Sale, (y) other pari passu
            Indebtedness (provided that the Company shall also equally and
            ratably reduce Indebtedness under the Notes by making an offer (in
            accordance with the procedures set forth below for an Asset Sale) to
            all Holders to purchase at a purchase price equal to 100% of the
            principal amount thereof, plus accrued and unpaid interest and
            Additional Interest, if any, the pro rata principal amount of
            Notes), or (z) Indebtedness of a Restricted Subsidiary that is not a
            Guarantor, in each case other than Indebtedness owed to any Parent,
            the Company or any of their respective Affiliates;

                  (2) to acquire all or substantially all of the assets of, or
            any Capital Stock of, another Permitted Business; provided that in
            the case of any such

                                      -73-

<PAGE>

            acquisition of Capital Stock, the Permitted Business is or becomes a
            Restricted Subsidiary of the Company;

                  (3) to make a capital expenditure; or

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

            (b) enter into a binding commitment to apply the Net Proceeds
      pursuant to clause (a) (2), (3) or (4) above, provided that such binding
      commitment shall be treated as a permitted application of the Net Proceeds
      from the date of such commitment until the earlier of (x) the date on
      which such acquisition or expenditure is consummated, and (y) the 180th
      day following the expiration of the aforementioned 365 day period.

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

            Any Net Proceeds from Asset Sales that are not applied or invested
as provided in the second paragraph of this Section 4.10 will constitute "Excess
Proceeds." When the aggregate amount of Excess Proceeds exceeds $15.0 million,
within ten Business Days thereof, the Company will make an offer to all holders
of Notes (an "Asset Sale Offer") and all holders of other Indebtedness that is
pari passu with the notes containing provisions similar to those set forth in
this Indenture with respect to offers to purchase or redeem with the proceeds of
sales of assets to purchase the maximum principal amount of Notes and such other
pari passu Indebtedness that may be purchased out of the Excess Proceeds. The
offer price in any Asset Sale Offer will be equal to 100% of the principal
amount of the Notes and such other pari passu Indebtedness plus accrued and
unpaid interest and Additional Interest, if any, on the Notes and such other
pari passu Indebtedness, to, but excluding, the date of purchase and will be
payable in cash. If any Excess Proceeds remain after consummation of an Asset
Sale Offer, the Company may use those Excess Proceeds for any purpose not
otherwise prohibited by this Indenture. Upon completion of each Asset Sale
Offer, the amount of Excess Proceeds will be reset at zero.

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

            Not later than the date upon which written notice of an Asset Sale
Offer is delivered to the Trustee as provided above, the Company shall deliver
to the Trustee an Officers' Certificate as to (i) the amount of the Excess
Proceeds, (ii) the allocation of the Net Proceeds from the Asset Sales pursuant
to which such Asset Sale Offer is being made and (iii) the compliance of such
allocation with the provisions of Section 4.10. Upon the expiration of the
period for which the Asset Sale Offer remains open (the "Offer Period"), the
Company shall

                                      -74-

<PAGE>

deliver to the Trustee for cancellation the Notes or portions thereof that have
been properly tendered to and are to be accepted by the Company. Upon receipt
from the Company of the purchase price for the Notes accepted for payment, the
Trustee shall promptly (but in any case not later than the Business Day after
the Trustee receives such amounts) mail or deliver to each tendering Holder an
amount equal to the purchase price of the Notes tendered by such Holder and
accepted by the Company for purchase. In the event that the Excess Proceeds
delivered by the Company to the Trustee is greater than the purchase price of
the Notes tendered, the Trustee shall deliver the excess to the Company
immediately after the expiration of the Offer Period for application in
accordance with this Section 4.10.

            Holders electing to have a Note purchased shall be required to
surrender the Note, with the form entitled "Option of Holder to Elect Purchase"
attached to the Note duly completed, to the Company at the address specified in
the notice at least three Business Days prior to the purchase date. Holders
shall be entitled to withdraw their election if the Trustee or the Company
receives not later than one Business Day prior to the purchase date, a telegram,
telex, facsimile transmission or letter setting forth the name of the Holder,
the principal amount of the Note which was delivered by the Holder for purchase
and a statement that such Holder is withdrawing his election to have such Note
purchased. If at the end of the Offer Period more Notes are tendered pursuant to
an Asset Sale Offer than the Company is required to purchase, selection of such
Notes for purchase shall be made by the Trustee in accordance with Section 3.02
hereof; provided that no Notes of $1,000 or less shall be purchased in part.

            Notices of an Asset Sale Offer shall be mailed by first class mail,
postage prepaid, at least 30 but not more than 60 days before the purchase date
to each Holder at such Holder's registered address. If any Note is to be
purchased in part only, any notice of purchase that relates to such Security
shall state the portion of the principal amount thereof that is to be purchased.

            A new Note in principal amount equal to the unpurchased portion of
any Note purchased in part shall be issued in the name of the Holder thereof
upon cancellation of the original Note in accordance with Section 2.02 hereof.
On and after the purchase date, unless the Company defaults in payment of the
purchase price, interest shall cease to accrue on Notes or portions thereof
purchased.

Section 4.11 Transactions with Affiliates.

            (a) the Company will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate of the Company (each, an "Affiliate Transaction"), involving
aggregate consideration in excess of $1.0 million, unless:

            (1) the Affiliate Transaction is on terms that are not materially
      less favorable to the Company or the relevant Restricted Subsidiary than
      those that would have been obtained in a comparable transaction by the
      Company or such Restricted Subsidiary with an unrelated Person; and

                                      -75-

<PAGE>

            (2) the Company delivers to the Trustee:

                  (A) with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $5.0 million, a resolution of the Board of Directors of
            the Company certifying that such Affiliate Transaction complies with
            this Section 4.11 and that such Affiliate Transaction has been
            approved by a majority of the disinterested members, if any, of the
            Board of Directors of the Company; and

                  (B) with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $25.0 million, an opinion as to the fairness to the
            Company or such Restricted Subsidiary of such Affiliate Transaction
            from a financial point of view issued by an accounting, appraisal or
            investment banking firm of national standing.

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

            (1) any employment agreement, employee benefit plan, officer or
      director indemnification agreement or any similar arrangement entered into
      by the Company or any of its Restricted Subsidiaries in the ordinary
      course of business or consistent with past practice and payments pursuant
      thereto;

            (2) transactions (including a merger) between or among the Company
      and/or any of its Restricted Subsidiaries;

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

            (4) payment of reasonable fees to, and indemnity provided on behalf
      of, officers, directors, employees or consultants of the Company or any of
      its Restricted Subsidiaries or any Parent;

            (5) any issuance of Equity Interests (other than Disqualified Stock)
      of the Company to Affiliates of the Company or to any director, officer,
      employee or consultant of the Company or any Parent, and the granting and
      performance of registration rights;

            (6) Restricted Payments and Investments that do not violate Section
      4.07 hereof;

            (7) the entering into any agreement to pay, and the payment of,
      customary annual management, consulting, monitoring and advisory fees to
      the Equity Investors in an amount not to exceed in any four quarter period
      the greater of (x) $5.0 million and (y) 2.0% of Consolidated Cash Flow of
      the Company and its Restricted Subsidiaries for such period;

                                      -76-

<PAGE>

            (8) loans or advances to employees or consultants in the ordinary
      course of business or consistent with past practice not to exceed $2.5
      million in the aggregate at any one time outstanding;

            (9) any transaction effected as part of a Qualified Receivables
      Financing;

            (10) any transaction in which the Company or any of its Restricted
      Subsidiaries, as the case may be, delivers to the Trustee a letter from an
      accounting, appraisal or investment banking firm of national standing
      stating that such transaction is fair to the Company or such Restricted
      Subsidiary from a financial point of view or that such transaction meets
      the requirements of clause (1) of Section 4.11(a);

            (11) the existence of, or the performance by the Company or any of
      its Restricted Subsidiaries of its obligations under the terms of, any
      acquisition agreements or members' or stockholders agreement or related
      documents to which it is a party as of the date of this Indenture and any
      amendment thereto or similar agreements which it may enter into
      thereafter; provided, however, that the existence of, or the performance
      by the Company or any of its Restricted Subsidiaries of its obligations
      under, any future amendment to any such existing agreement or under any
      similar agreement entered into after the date of this Indenture shall only
      be permitted by this clause (11) to the extent that the terms of any such
      existing agreement, together with all amendments thereto, taken as a
      whole, or such new agreement are not, in the good faith judgment of the
      Company's Board of Directors, otherwise more disadvantageous to the
      Holders of the Notes taken as a whole than the original agreement as in
      effect on the date of this Indenture;

            (12) transactions with Unrestricted Subsidiaries, customers,
      clients, suppliers, joint venture partners or purchasers or sellers of
      goods or services, or lessors or lessees of property, in each case in the
      ordinary course of business and otherwise in compliance with the terms of
      this Indenture which are, in the aggregate (taking into account all the
      costs and benefits associated with such transactions), materially no less

      would have been obtained in a comparable transaction by the Company or
      such Restricted Subsidiary with an unrelated Person, in the good faith
      judgment of the Company's Board of Directors or senior management thereof,
      or are on terms at least as favorable as might reasonably have been
      obtained at such time from an unaffiliated party;

            (13) (x) guarantees of performance by the Company and its Restricted
      Subsidiaries of Unrestricted Subsidiaries of the Company in the ordinary

      borrowed money, and (y) pledges of Equity Interests of Unrestricted
      Subsidiaries of the Company for the benefit of lenders of Unrestricted
      Subsidiaries of the Company;

            (14) if such Affiliate Transaction is with a Person in its capacity
      as a holder of Indebtedness or Capital Stock of the Company or any
      Restricted Subsidiary where such Person is treated no more favorably than
      the holders of Indebtedness or Capital Stock of the Company or any
      Restricted Subsidiary;

            (15) transactions effected pursuant to agreements in effect on the
      Issue Date and any amendment, modification or replacement of such
      agreement (so long as such amendment or replacement is not, in the good
      faith judgment of the Company's Board of Directors, materially more
      disadvantageous to the Holders of the Notes, taken as a whole, than the
      original agreement as in effect on the Issue Date);

            (16) payments to the Equity Investors made for any financial
      advisory, financing or other investment banking activities, including
      without limitation, in connection with acquisitions or divestitures, which

Section 4.12 Liens.

            The Company will not, and will 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 securing Indebtedness (other than
Permitted Liens) that ranks pari passu with or is subordinated to the Notes or
the Note Guarantees 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 (or, in the case
of subordinated Indebtedness, contractually prior or senior thereto, with the
same relative priority as the Notes shall have with respect to such subordinated
Indebtedness) until such time as such obligations are no longer secured by a
Lien.

Section 4.13 Business Activities.

            the Company will not, and will not permit any of its Restricted
Subsidiaries 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 Intentionally Omitted.

Section 4.15 Offer to Repurchase upon Change of Control.

            (a) Upon the occurrence of a Change of Control, the Company will
make an offer (a "Change of Control Offer") to each Holder of the Notes to
repurchase all or any part (equal to $1,000 or an integral multiple of $1,000)
of that Holder's Notes at a purchase price in cash equal to 101% of the
aggregate principal amount of Notes repurchased plus accrued and unpaid interest
and Additional Interest, if any, on the Notes repurchased to, but not including,
the date of purchase, subject to the rights of Holders on the relevant record
date to receive interest due on the relevant interest payment date (the "Change
of Control Payment"). Within 30 days following any Change of Control, except to
the extent that the Company has exercised its right to redeem the Notes in
accordance with Article 3 of this Indenture the Company will mail a notice

                                      -78-

<PAGE>

to each Holder describing the transaction or transactions that constitute the
Change of Control and stating:

            (1) that the Change of Control Offer is being made pursuant to this
      Section 4.15 and that all Notes properly tendered pursuant to such Change
      of Control Offer will be accepted for payment;

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

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

            (4) that, unless the Company defaults in the payment of the Change
      of Control Payment, all Notes accepted for payment pursuant to the Change
      of Control Offer will cease to accrue interest after the Change of Control
      Payment Date;

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

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

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

            The Company will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change in Control. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of this Section 4.15 hereof, the Company will comply with the
applicable securities laws and regulations and will not be deemed to have
breached their obligations under this Section 4.15 by virtue of such compliance.

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

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

                                      -79-

<PAGE>

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

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

            The Paying Agent will promptly mail or wire transfer to each Holder
properly tendered and so accepted the Change of Control Payment for such Notes.
The Company will execute and, upon receipt of an Authentication Order in
accordance with Section 2.02 hereof, the Trustee will promptly authenticate and
mail (or cause to be transferred by book entry) to each Holder a new Note equal
in principal amount to any unpurchased portion of the Notes surrendered, if any;
provided, that each new note will be in a principal amount of $1,000 or an
integral multiple of $1,000. Any Note so accepted for payment will cease to
accrue interest on and after the Change of Control Payment Date. The Company
will publicly announce the results of the Change of Control Offer on or as soon
as reasonably practicable after the Change of Control Payment Date.

            (c) Notwithstanding anything to the contrary in this Section 4.15,
the Company will not be required to make a Change of Control Offer upon a Change
of Control if (1) a third party makes the Change of Control Offer in the manner,
at the times and otherwise in compliance with the requirements set forth in this
Section 4.15 and purchases all Notes properly tendered and not withdrawn under
the Change of Control Offer, or (2) notice of redemption has been given pursuant
to Section 3.07 hereof, unless and until there is a default in payment of the
applicable redemption price.

Section 4.16 Payments for Consent.

            The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder 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 that consent, waive or agree to amend in the time frame set forth in the
solicitation documents relating to such consent, waiver or agreement.

Section 4.17 Additional Note Guarantees.

            If the Company or any of its Restricted Subsidiaries acquires or
creates another wholly-owned Domestic Subsidiary on or after the date of this
Indenture, then that newly acquired or created Domestic Subsidiary, if such
Subsidiary guarantees any Indebtedness of the Company (unless such Subsidiary is
a Receivables Subsidiary), shall become a Guarantor (which Note Guarantee shall
be senior to or pari passu with such Restricted Subsidiary's guarantee of such
other Indebtedness unless such other Indebtedness is Senior Indebtedness, in
which case the Note Guarantee may be subordinated to the guarantee of such
Senior Indebtedness to the same extent as the Notes are subordinated to such
Senior Indebtedness) and execute a supplemental indenture and deliver an Opinion
of Counsel satisfactory to the Trustee within 30 days of the date on which it
was acquired or created; provided that any Domestic Subsidiary that constitutes

                                      -80-

<PAGE>

an Immaterial Subsidiary need not become a Guarantor until such time as it (i)
ceases to be an Immaterial Subsidiary or (ii) guarantees the Credit Agreement.
The form of such supplemental indenture is attached hereto as Exhibit E hereto.

Section 4.18 Designation of Restricted and Unrestricted Subsidiaries.

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

            Any designation of a Subsidiary of the Company as an Unrestricted
Subsidiary will be evidenced to the Trustee by filing with the Trustee a
certified copy of a resolution of the Board of Directors of the Company giving
effect to such designation and an Officers' Certificate certifying that such
designation complied with the preceding conditions and was permitted by Section
4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the
preceding requirements as an Unrestricted Subsidiary, it will thereafter cease
to be an Unrestricted Subsidiary for purposes of this Indenture and any
Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted
Subsidiary of the Company as of such date and, if such Indebtedness is not
permitted to be incurred as of such date under Section 4.09 hereof, the Company
will be in default of such covenant. The Board of Directors of the Company may
at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary
of the Company; provided that such designation will 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
will only be permitted if (1) (x) the Company could incur such Indebtedness
pursuant to the Fixed Charge Coverage Ratio test, described in Section 4.09(a)
hereof, or (y) the Fixed Charge Coverage Ratio for the Company and its
Restricted Subsidiaries would be greater than such ratio for the Company and its
Restricted Subsidiaries immediately prior to such designation, in each case on a
pro forma basis taking into account such designation; and (2) no Default or
Event of Default would be in existence following such designation.

Section 4.19 Changes in Covenants upon Notes Being Rated Investment Grade.

            If on any date following the Issue Date: (i) the Notes are assigned
an Investment Grade Rating from both of the Rating Agencies and (ii) no Default
or Event of Default shall have occurred and be continuing, then the Company
shall provide written notice to such effect to the Trustee and, beginning on
that day, the covenants contained in Sections 4.06, 4.07, 4.08, 4.09, 4.10,
4.11, 4.13 and 4.18 hereof, and clause (4) of Section 5.01 shall terminate
(provided that

                                      -81-

<PAGE>

failure to provide such notice shall not result in a Default or Event of Default
or the Company having to comply with such provisions).

Section 5.01 Merger, Consolidation, or Sale of Assets.

            The Company will not, directly or indirectly, consolidate or merge
with or into another Person; or sell, assign, transfer, convey or otherwise
dispose of all or substantially all of its properties or assets (determined on a
consolidated basis for the Company and its Restricted Subsidiaries), in one or
more related transactions to another Person, unless:

            (1) either:

                  (A) the Company is the surviving entity; or

                  (B) the Person formed by or surviving any such consolidation
            or merger (if other than the Company) or to which such sale,
            assignment, transfer, conveyance or other disposition has been made
            is a corporation, partnership or limited liability company organized
            or existing under the laws of the United States, any state of the
            United States or the District of Columbia;

            (2) the Person formed by or surviving any such consolidation or
      merger (if other than the Company) or the Person to which such sale,

      assumes all the obligations of the Company under the Notes, this Indenture
      and the Registration Rights Agreement, in each case, pursuant to
      agreements reasonably satisfactory to the Trustee;

            (3) immediately after such transaction, no Default or Event of
      Default exists; and

            (4) (a) the Company or the Person formed by or surviving any such
      consolidation or merger (if other than the Company), or to which such
      sale, assignment, transfer, conveyance or other disposition has been made
      would, on the date of such transaction after giving pro forma effect
      thereto and to any related financing transactions as if the same had
      occurred at the beginning of the applicable four-quarter period be
      permitted to incur at least $1.00 of additional Indebtedness pursuant to
      the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) hereof;
      or

            (b) the Fixed Charge Coverage Ratio for the successor entity and its
      Restricted Subsidiaries, on the date of and after giving pro forma effect
      to such acquisition and such incurrence or issuance, would not be less
      than such ratio for the Company and its Restricted Subsidiaries
      immediately prior to such transaction.

            In addition, the Company may not, directly or indirectly, lease all
or substantially all of the properties and assets (determined on a consolidated
basis for the Company and its Restricted Subsidiaries), in one or more related
transactions, to any other Person.

            This Section 5.01 will not apply to:

      of reincorporating the Company in another jurisdiction; or

            (2) any consolidation or merger, or any sale, assignment, transfer,
      conveyance, lease or other disposition of assets between or among the
      Company and any of its Restricted Subsidiaries.

Section 5.02 Successor Substituted.

            Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the
properties or assets of the Company in a transaction that is subject to, and
that complies with the provisions of, Section 5.01 hereof, the successor Person
formed by such consolidation or into or with which the Company is merged or to
which such sale, assignment, transfer, lease, 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, assignment, transfer, lease, conveyance or
other disposition, the provisions of this Indenture referring to the "Company"
shall refer instead to the successor Person 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 shall not be relieved from the
obligation to pay the principal of and interest on the Notes except in the case
of a sale of all or substantially all of the Company's properties or assets in a
transaction that is subject to, and that complies with the provisions of,
Section 5.01 hereof.

Section 6.01 Events of Default.

            Each of the following is an "Event of Default":

            (1) default for 30 days in the payment when due of interest on, or
      Additional Interest, if any, with respect to the Notes, whether or not
      such payment is prohibited by the provisions described in Article 10
      hereof;

            (2) default in the payment when due (at maturity, upon redemption or
      otherwise) of the principal of, or premium, if any, on the Notes, whether
      or not such payment is prohibited by the provisions described in Article
      10 hereof;

            (3) failure by the Company or any of its Restricted Subsidiaries to
      comply with the provisions of Sections 4.15 or 5.01 hereof;

      this Indenture;

            (5) 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 Significant
      Subsidiaries or group of Restricted Subsidiaries that taken as a whole
      would constitute a Significant Subsidiary (or the payment of which is
      guaranteed by the Company or any of its Restricted Subsidiaries), whether
      such Indebtedness or guarantee now exists, or is created after the date of
      this Indenture (but excluding Indebtedness owing to the Company or a
      Restricted Subsidiary), if that default:

                  (A) is caused by a failure to pay principal on such
            Indebtedness prior to the expiration of the grace period provided in
            such Indebtedness upon the Stated Maturity of such Indebtedness (a
            "Payment Default"); or

                  (B) results in the acceleration of such Indebtedness prior to
            its Stated Maturity,

      and, in each case, the principal amount of any such Indebtedness, together
      with the principal amount of any other such Indebtedness under which there

      excess of $25.0 million (net of any amounts which are covered by insurance
      or bonded), which judgments are not paid, waived, satisfied, discharged or
      stayed for a period of 60 days;

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

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

            (8) 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 any group of
            Restricted Subsidiaries that, taken together, would constitute a
            Significant Subsidiary in an involuntary case;

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

            consecutive days; and

            (9) except as permitted by this Indenture, any Note Guarantee of any
      Significant Subsidiary or group of Restricted Subsidiaries that taken as a

      proceeding to be unenforceable or invalid or ceases for any reason to be
      in full force and effect (other than in accordance with the terms of such
      Note Guarantee and this Indenture), or any Guarantor, or any Person acting
      on behalf of any Guarantor, denies or disaffirms its obligations under its
      Note Guarantee and such Default continues for 10 days.

Section 6.02 Acceleration.

            In the case of an Event of Default specified in clause (7) or (8) of
Section 6.01 hereof, with respect to the Company, any Restricted Subsidiary of
the Company that is a Significant Subsidiary or any group of Restricted
Subsidiaries of the Company that, taken 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 aggregate principal
amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately; provided that any such declaration of acceleration shall
not become effective until the earlier of (x) five Business Days after receipt
of the acceleration notice by the Bank Agent and the Company or (y) acceleration
of the Indebtedness under the Credit Agreement; provided further that such
acceleration shall be automatically rescinded and annulled without any further
action required on the part of the Trustee or the Holders in the event that any
and all Events of Default specified in the acceleration notice under this
Indenture shall have been cured, waived or otherwise remedied as provided in
this Indenture prior to the expiration of the period referred to in the
preceding clauses (x) and (y).

                                      -85-

<PAGE>

            Upon any such declaration, the Notes shall become due and payable
immediately.

            The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may, on behalf of all of the
Holders, rescind an acceleration and its consequences, if the rescission would
not conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, interest or premium or Additional Interest, if
any, that has become due solely because of the acceleration) have been cured or
waived.

            In the event of any Event of Default specified in clause (5) of
Section 6.01, such Event of Default and all consequences thereof (excluding,
however, any resulting payment default) will be annulled, waived and rescinded,
automatically and without any action by the Trustee or the Holders of the Notes,
if within 20 days after such Event of Default arose the Company delivers an
Officers' Certificate to the Trustee stating that (x) the Indebtedness or
guarantee that is the basis for such Event of Default has been discharged or (y)
the Holders thereof have rescinded or waived the acceleration, notice or action
(as the case may be) giving rise to such Event of Default or (z) the default
that is the basis for such Event of Default has been cured, it being understood
that in no event shall an acceleration of the principal amount of the Notes as
described above be annulled, waived or rescinded upon the happening of any such
events.

Section 6.03 Other Remedies.

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

            The Trustee may maintain a proceeding 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 not less than a majority in aggregate principal amount of
the then outstanding Notes by notice to the Trustee may on behalf of the Holders
of all of the Notes rescind an acceleration or waive an existing Default or
Event of Default and its consequences hereunder, except a continuing Default or
Event of Default in the payment of the principal of, premium and Additional
Interest, if any, or interest on, the Notes (including in connection with an
offer to purchase). Upon any such rescission or 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 aggregate 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 Holder may pursue a remedy with respect to this Indenture or the
      Notes only if:

            (1) such Holder has previously given the Trustee written notice that
      an Event of Default is continuing;

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

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

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

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

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

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

Section 6.08 Collection Suit by Trustee.

amount of principal of, premium and Additional Interest, if any, and interest
remaining unpaid on, the Notes and interest on overdue principal and, to the
extent lawful, interest and such further amount as shall be sufficient to cover
the costs

disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable and documented 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

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.

            If the Trustee collects any money pursuant to this Article 6, it
shall pay out the money in the following order:

            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 and
documented attorneys' fees and expenses against any party litigant in the suit,

Section 7.01 Duties of Trustee.

            (a) The Trustee, prior to the occurrence of an Event of Default of
which a Responsible Officer of the Trustee shall have actual knowledge and after
the curing of all such Events of Defaults which may have occurred, undertakes to
perform such duties and only such duties as are specifically set forth in this
Indenture. If an Event of Default of which a Responsible Officer of the Trustee
shall have actual knowledge has occurred and is continuing, the Trustee will
exercise such of the rights and powers vested in it by this Indenture, and use
the same degree of care and skill in its exercise, as a prudent person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

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

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

            (2) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, with respect to certificates or opinions specifically required by
      any provision hereof to be furnished to it, the Trustee will examine the
      certificates and opinions to determine whether or not they conform to the
      requirements of this Indenture; provided, however, that the Trustee shall
      not be responsible for the accuracy or content of any resolution,
      certificate, statement, opinion, report, document, order or other
      instrument furnished to it hereunder.

                                      -89-

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

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

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

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

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

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

Section 7.02 Rights of Trustee.

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

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

            (c) The Trustee may execute any of the trusts or powers hereunder
and perform any duties hereunder either directly or through its attorneys and
agents and will not be responsible for the misconduct or negligence of any agent
appointed with due care.

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

                                      -90-

<PAGE>

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

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

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

            (h) the Trustee shall not be deemed to have notice of any Default or
Event of Default unless a Responsible Officer of the Trustee has knowledge
thereof or unless written notice of any event which is in fact such a default is
received by the Trustee at the Corporate Trust Office of the Trustee, and such
notice references the Notes and this Indenture;

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

            (j) the Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded; and

            (k) The right of the Trustee to perform any discretionary act
enumerated in this Indenture shall not be construed as a duty, and the Trustee
shall not be answerable for other than its negligence or willful misconduct in
the performance of such act.

Section 7.03 Individual Rights of Trustee.

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

Section 7.04 Trustee's Disclaimer.

            The Trustee will not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Notes, it shall not be

<PAGE>

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 will not be
responsible for the use or application of any money received by any Paying Agent
other than the Trustee, and it will 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 or the legality or
validity of the Notes or this Indenture other than its certificate of
authentication.

Section 7.05 Notice of Defaults.

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

Section 7.06 Reports by Trustee to Holders of the Notes.

            (a) Within 60 days after each May 15 beginning with the May 15
following the date of this Indenture, and for so long as Notes remain
outstanding, the Trustee will 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
will comply with TIA Section 313(b)(2). The Trustee will also transmit by mail
all reports as required by TIA Section 313(c).

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

Section 7.07 Compensation and Indemnity.

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

            (b) The Company and each Guarantor, jointly and severally, will
indemnify the Trustee and any director, officer, employee or agent of the
Trustee against any and all losses, liabilities, claims, damages or expenses
incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, including, without
limitation, the reasonable and documented costs and expenses of enforcing this
Indenture against the Company and the Guarantors (including this Section 7.07)
and defending itself against any claim (whether asserted by the Company, the
Guarantors, any Holder or any other Person) or liability in

                                      -92-

<PAGE>

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 own negligence, bad faith or willful misconduct. The Trustee
will notify the Company promptly of any claim of which a Responsible Officer has
received written notice for which it may seek indemnity. Failure by the Trustee
to so notify the Company will not relieve the Company or any of the Guarantors
of their obligations hereunder. The Company or such Guarantor will defend the
claim and the Trustee will cooperate in the defense. The Trustee may have
separate counsel and the Company and the Guarantors, as applicable, will pay the
reasonable and documented fees and expenses of such counsel provided, however
that the Company and any Guarantor shall not be required to pay such fees and
expenses if it assumes such indemnified parties' defense and, in such
indemnified parties' reasonable judgment, there is no conflict of interest
between the Company and the Guarantors, as applicable, and such parties in
connection with such defense. Neither the Company nor any Guarantor need pay for
any settlement made without its consent, which consent will not be unreasonably
withheld.

            (c) The obligations of the Company and the Guarantors under this
Section 7.07 will survive the satisfaction and discharge of this Indenture.

            (d) To secure the Company's and the Guarantors' payment obligations
in this Section 7.07, the Trustee will have a Lien prior to the Notes on all
money or property held or collected by the Trustee, except that held in trust to
pay principal and interest on particular Notes. Such Lien will survive the
satisfaction and discharge of this Indenture.

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

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

Section 7.08 Replacement of Trustee.

            (a) A resignation or removal of the Trustee and appointment of a
successor Trustee will 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 aggregate 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:

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

            (2) 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;

      property; or

<PAGE>

            (4) the Trustee becomes incapable of acting.

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

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

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

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

Section 7.09 Successor Trustee by Merger, Etc.

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

Section 7.10 Eligibility; Disqualification.

            There will 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

Section 8.03 Covenant Defeasance.

            Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company and each of the Guarantors will,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be released from each of their obligations under the covenants contained in
Sections 4.03, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17,
4.18 and 4.19 and clauses (3) and (4) of Section 5.01 hereof with respect to the
outstanding Notes on and after the date the conditions set forth in Section 8.04
hereof are satisfied (hereinafter, "Covenant Defeasance"), and the Notes will
thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but will continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Notes will not be deemed outstanding for accounting purposes). For this purpose,
Covenant Defeasance means that, with respect to the outstanding Notes and Note
Guarantees, the Company and the Guarantors may omit to comply with and will have
no liability in respect of any term, condition or limitation set forth in any
such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other document and such
omission to comply will not constitute a Default or an Event of Default under
Section 6.01 hereof, but, except as specified above, the remainder of this
Indenture and such Notes and Note Guarantees will be unaffected thereby. In
addition, upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, subject to the satisfaction of the conditions
set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(6) hereof will
not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

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

            (1) the Company must irrevocably deposit with the Trustee, in trust,
      for the benefit of the Holders, 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 investment bank,
      appraisal firm, or firm of independent public accountants, to pay the
      principal of, premium and Additional Interest, if any, and interest on,
      the outstanding Notes on the stated date for payment thereof or on the
      applicable redemption date, as the case may be, and the Company must
      specify whether the Notes are being defeased to such stated date for
      payment or to a particular redemption date;

            (2) in the case of an election under Section 8.02 hereof, the
      Company must deliver to the Trustee an Opinion of Counsel 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,

                                      -96-

<PAGE>

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

            (3) in the case of an election under Section 8.03 hereof, the
      Company must deliver to the Trustee an Opinion of Counsel 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;

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

            (5) such Legal Defeasance or Covenant Defeasance will not result in
      a breach or violation of, or constitute a default under, any material
      agreement or instrument (other than this Indenture) to which the Company
      or any of its Subsidiaries is a party or by which the Company or any of
      its Subsidiaries is bound, including the Credit Agreement;

            (6) the Company is not prohibited from making payments in respect of
      the Notes by the provisions described in Article 10 hereof;

            (7) the Company must deliver to the Trustee an Officers' Certificate
      stating that the deposit was not made by the Company with the intent of
      preferring the Holders over the other creditors of the Company with the
      intent of defeating, hindering, delaying or defrauding any creditors of
      the Company or others; and

            (8) 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.

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

                                      -97-

<PAGE>

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

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

Section 8.06 Repayment to Company.

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of, premium or
Additional Interest, if any, or interest on, any Note and remaining unclaimed
for two years after such principal, premium or Additional Interest, 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) will be discharged from such trust; and the
Holder of such Note will thereafter be permitted to 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, will thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company causes to be published once, in the New York Times and
The Wall Street Journal (national edition), notice that such money remains
unclaimed and that, after a date specified therein, which will not be less than
30 days from the date of such notification or publication, any unclaimed balance
of such money then remaining will be repaid to the Company.

Section 8.07 Reinstatement.

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

                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

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

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

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

            (3) to provide for the assumption of the Company's or a Guarantor's
      obligations to the Holders of the Notes and Note Guarantees by a successor
      to the Company or such Guarantor pursuant to Article 5 or Article 11
      hereof;

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

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

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

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

            (8) to allow any Guarantor to execute a supplemental indenture
      and/or a Note Guarantee with respect to the Notes and to release
      Guarantors from the Note Guarantee in accordance with the terms of this
      Indenture;

            (9) to comply with the rules of any applicable securities
      depositary; or

            (10) to provide for a successor Trustee in accordance with the terms
      of this Indenture or to otherwise comply with any requirement of this
      Indenture.

            Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
indenture, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee will join with the Company and the Guarantors in the
execution of any amended or supplemental indenture authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee will not

                                      -99-

<PAGE>

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.

            Except as provided below in this Section 9.02, the Company, the
Guarantors and the Trustee may amend or supplement this Indenture (including,
without limitation, Sections 4.10 and 4.15 hereof) and the Notes or the Note
Guarantee with the consent of the Company and Holders of at least a majority in
aggregate principal amount of the then outstanding Notes voting as a single
class (including, without limitation, consents obtained in connection with a
tender offer or exchange offer for, or purchase of, the Notes), and, subject to
Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other
than a Default or Event of Default in the payment of the principal of, premium
or Additional Interest, if any, or interest on, the Notes, except a payment
default resulting from an acceleration that has been rescinded) or compliance
with any provision of this Indenture or the Notes or the Note Guarantee may be
waived with the consent of the Company and Holders of a majority in aggregate
principal amount of the then outstanding Notes (including, without limitation,
Additional Notes, if any) voting as a single class (including, without
limitation, consents obtained in connection with a tender offer or exchange
offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which
Notes are considered to be "outstanding" for purposes of this Section 9.02.

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

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

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

                                      -100-

<PAGE>

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

            (2) reduce the principal of or change the fixed maturity of any Note
      or alter the provisions with respect to the redemption of the Notes
      (except as provided above with respect to Sections 4.10 and 4.15 hereof);

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

            (4) waive a Default or Event of Default in the payment of principal
      of, or premium or Additional Interest, if any, or interest 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 then outstanding
      Notes and a waiver of the payment default that resulted from such
      acceleration);

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

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

            (7) waive a redemption payment with respect to any Note (other than
      a payment required by Sections 4.10 or 4.15 hereof);

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

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

            (10) modify the subordination provisions of this Indenture in any
      manner adverse to the Holders; or

            (11) 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 will be
set forth in a amended or supplemental indenture that complies with the TIA as
then in effect.

Section 9.04 Revocation and Effect of Consents.

            Until an amendment, supplement or waiver becomes effective, a
consent to it by a Holder of a Note is a continuing consent by 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

                                      -101-

<PAGE>

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 amendment, supplement
or waiver becomes effective. After an amendment, supplement or waiver becomes
effective in accordance with its terms, it thereafter binds every Holder.

Section 9.05 Notation on or Exchange of Notes.

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

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

Section 9.06 Trustee to Sign Amendments, Etc.

            The Trustee will sign any amended or supplemental indenture
authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Company may not sign an amended or supplemental indenture until the Board of
Directors of the Company approves it. In executing any amended or supplemental
indenture, the Trustee will be provided with and (subject to Section 7.01
hereof) will be fully protected in relying upon, in addition to the documents
required by Section 13.04 hereof, an Officers' Certificate and an Opinion of
Counsel stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

                                  SUBORDINATION

Section 10.01 Agreement to Subordinate.

            The Company agrees, and each Holder by accepting a Note agrees, that
the Indebtedness evidenced by the Notes is subordinated in right of payment, to
the extent and in the manner provided in this Article 10, to the prior payment
in full in cash or Cash Equivalents of all Obligations due in respect of
existing and future Senior Indebtedness. In addition, until all Obligations due
with respect to Senior Indebtedness are paid in full in cash or Cash Equivalents
(including, with respect to Senior Indebtedness, any interest accruing after the
commencement of any proceeding described in Section 10.02 at the rate specified
in the applicable Designated Senior Indebtedness, whether or not interest is an
allowed claim enforceable against the Company in such proceeding), any such
distribution to which Holders would be entitled shall be made to the holders of
Senior Indebtedness (except that Holders may receive and retain Permitted Junior
Securities and payments made from any trust described under Articles 8 or 12
hereof).

Section 10.02 Liquidation; Dissolution; Bankruptcy.

            The holders of Senior Indebtedness shall be entitled to receive
payment in full in cash or Cash Equivalents of all Obligations due in respect of
Senior Indebtedness (including with respect to Designated Senior Indebtedness,
any interest accruing after the commencement of any proceeding described in this
Section 10.02 at the rate specified in the applicable Designated Senior
Indebtedness whether or not interest is an allowed claim enforceable against the
Company in such proceeding) before the Holders shall be entitled to receive any
payment on account of Senior Subordinated Obligations or any payment to acquire
any of the Notes for cash, properties or securities, or any distribution with
respect to the Notes of any cash, property, or securities (except that Holders
may receive and retain Permitted Junior Securities and payments made from any
trust described under Articles 8 and 12 hereof), in the event of any
distribution to creditors of the Company in (a) any liquidation or dissolution
of the Company; (b) a bankruptcy, reorganization, insolvency, receivership or
similar proceeding relating to the Company or its property; (c) an assignment
for the benefit of its creditors; or (d) any marshaling of the Company's assets

Section 10.03 Default on Designated Senior Indebtedness.

            (a) The Company shall not make any payment in respect of any Senior
Subordinated Obligations (except in Permitted Junior Securities or from any
trust described under Articles 8 and 12 hereof) if:

            (i) a payment default on Designated Senior Indebtedness occurs and
      is continuing; or

            (ii) any other default (a "non-payment default") occurs and is
      continuing on any series of Designated Senior Indebtedness that permits
      holders of that series of Designated Senior Indebtedness to accelerate its
      maturity and a Responsible Officer of the Trustee receives actual notice
      of such default (a "Payment Blockage Notice") from the trustee or other
      representative for the holders of any Designated Senior Indebtedness, or
      the holders of at least a majority of the outstanding principal amount of
      such Designated Senior Indebtedness.

            (b) Payments on the Notes may and shall be resumed:

            (i) in the case of a payment default in respect of Designated Senior
      Indebtedness, upon the date on which such default is cured or waived; and

            (ii) in the case of a non-payment default in respect of Designated
      Senior Indebtedness, upon the earlier of (x) the date on which such
      non-payment default is cured or waived or (y) 179 days after the date on
      which the applicable Payment Blockage Notice is received.

No new Payment Blockage Notice may be delivered unless and until 360 days have
elapsed since the delivery of the immediately prior Payment Blockage Notice and
all scheduled payments of principal, interest and premium and Additional
Interest, if any, on the Notes that have come due have been paid in full in
cash.

                                      -103-

<PAGE>

            (c) No non-payment default that existed or was continuing on the
date of delivery of any Payment Blockage Notice to the Trustee shall be, or be
made, the basis for a subsequent Payment Blockage Notice.

            (d) If the Trustee or any Holder receives a payment in respect of
the Notes (except in Permitted Junior Securities or from the trust described
under Articles 8 or 12 hereof) when (i) the payment is prohibited by this
Article 10 and (ii) the Trustee or the Holder has actual knowledge that the
payment is prohibited, the Trustee or the Holder, as the case may be, shall hold
the payment in trust for the benefit of the holders of Senior Indebtedness. Upon
the proper written request of the holders of Senior Indebtedness, the Trustee or
the Holder, as the case may be, shall deliver the amounts in trust to the
holders of Senior Indebtedness or their proper representative.

Section 10.04 Acceleration of Notes.

            If payment of the Notes is accelerated because of an Event of
Default, the Company shall promptly notify holders of Senior Indebtedness and
the Trustee shall promptly notify the Bank Agent of the acceleration.

Section 10.05 When Distribution Must Be Paid Over.

            In the event that the Trustee or any Holder receives any payment in
respect of the Notes (except in Permitted Junior Securities or from any trust
described under Articles 8 or 12 hereof) when (x) the payment is prohibited by
this Article 10 and (y) a Responsible Officer of the Trustee or such Holder, as
applicable, has actual knowledge that such payment is prohibited by this Article
10, such payment shall be held by the Trustee or such Holder, as applicable, in
trust for the benefit of, and shall be paid forthwith over and delivered, upon
written request, to the holders of Senior Indebtedness as their interests may
appear or their representative.

            With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform only such obligations on the part of the Trustee as are
specifically set forth in this Article 10, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness, and shall not be
liable to any such holders if the Trustee shall pay over or distribute to or on
behalf of Holders or the Company or any other Person money or assets to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article
10, except if such payment is made as a result of the willful misconduct or
gross negligence of the Trustee.

Section 10.06 Notice by the Company.

            The Company shall promptly notify the Trustee and the Paying Agent
in writing of any facts known to the Company that would cause a payment of any
Obligations with respect to the Notes to violate this Article 10, but failure to
give such notice shall not affect the subordination of the Notes to the Senior
Indebtedness as provided in this Article 10.

Section 10.07 Subrogation.

            After all Senior Indebtedness is paid in full and until the Notes
are paid in full, Holders shall be subrogated (equally and ratably with all
other Indebtedness pari passu with the Notes) to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the Holders have been applied to
the payment of Senior Indebtedness. A distribution made under this Article 10 to
holders of Senior Indebtedness that otherwise would have been made to Holders is
not, as between the Company and Holders, a payment by the Company on the Notes.

Section 10.08 Relative Rights.

            This Article 10 defines the relative rights of Holders and holders
of Senior Indebtedness. Nothing in this Indenture shall:

            (i) impair, as between the Company and Holders, the obligation of
      the Company, which is absolute and unconditional, to pay principal of and
      interest on the Notes in accordance with their terms;

            (ii) affect the relative rights of Holders of Notes and creditors of
      the Company other than their rights in relation to holders of Senior
      Indebtedness; or

            (iii) prevent the Trustee or any Holder of Notes from exercising its
      available remedies upon a Default or Event of Default, subject to the
      rights of holders and owners of Senior Indebtedness to receive
      distributions and payments otherwise payable to Holders.

            If the Company fails because of this Article 10 to pay principal of
or interest on a Note on the due date, the failure is still a Default or Event
of Default.

Section 10.09 Subordination May Not Be Impaired by the Company.

            No right of any holder of Senior Indebtedness to enforce the
subordination of the Indebtedness evidenced by the Notes shall be impaired by
any act or failure to act by the Company or any Holder or by the failure of the
Company or any Holder to comply with this Indenture.

Section 10.10 Rights of Trustee and Paying Agent.

            Notwithstanding this Article 10 or any other provision of this
Indenture, the Trustee shall not be charged with knowledge of the existence of
any facts that would prohibit the making of any payment or distribution by the
Trustee, and the Trustee and the Paying Agent may continue to make payments on
the Notes, unless the Trustee shall have received at its Corporate Trust Office
at least five Business Days prior to the date of such payment written notice of
facts that would cause the payment of any Obligations with respect to the Notes
to violate this Article 10. Only the Company may give the notice. Nothing in
this Article 10 shall impair the claims of, or payments to, the Trustee under or
pursuant to Section 7.07 hereof.

                                      -105-

<PAGE>

            The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee. Any
Agent may do the same with like rights.

Section 10.11 Authorization to Effect Subordination.

            Each Holder, by the Holder's acceptance of the Notes, authorizes and
directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 10, and appoints the Trustee to act as such Holder's attorney-in-fact
for any and all such purposes. If the Trustee does not file a proper proof of
claim or proof of debt in the form required in any proceeding referred to in
Section 6.09 hereof at least 30 days before the expiration of the time to file
such claim, the lenders under the Credit Agreement are hereby authorized to file
an appropriate claim for and on behalf of the Holders.

                                   ARTICLE 11

                                 NOTE GUARANTEES

Section 11.01 Guarantee.

            (a) Subject to this Article 11, each of the Guarantors hereby,
jointly and severally, unconditionally guarantees to each Holder of a Note
authenticated and delivered by the Trustee and to the Trustee and its successors
and assigns, irrespective of the validity and enforceability of this Indenture,
the Notes or the obligations of the Company hereunder or thereunder, that:

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

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

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

            (b) The Guarantors hereby agree that their obligations hereunder are
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

                                      -106-

<PAGE>

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. 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 covenant that this Note Guarantee
will not be discharged except by complete performance of the obligations
contained in the Notes and this Indenture.

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

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

Section 11.02 Limitation on Guarantor Liability.

            Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Note Guarantee of
such Guarantor not constitute a fraudulent transfer or conveyance for purposes
of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act or any similar federal or state law to the extent applicable to any
Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders
and the Guarantors hereby irrevocably agree that the obligations of such
Guarantor will be limited to the maximum amount that will, after giving effect
to such maximum amount and all other contingent and fixed liabilities of such
Guarantor that are relevant under such laws, and after giving effect to any
collections from, rights to receive contribution from or payments made by or on
behalf of any other Guarantor in respect of the obligations of such other
Guarantor under this Article 11, result in the obligations of such Guarantor
under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 11.03 Intentionally Omitted.

Section 11.04 Guarantors May Consolidate, Etc., on Certain Terms.

            Except as otherwise provided in this Section 11.04, no Guarantor may
sell or otherwise dispose of all or substantially all of its assets to, or
consolidate with or merge with or into (whether or not such Guarantor is the
surviving Person) another Person, other than the Company or another Guarantor,
unless:

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

            (2) 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 assumes all the obligations of that
            Guarantor under this Indenture, its Note Guarantee and the
            Registration Rights Agreement on the terms set forth herein or
            therein, pursuant to a supplemental indenture in the form attached
            hereto as Exhibit E; or

                  (b) in the case of any such sale or disposition (including by
            way of any such consolidation or merger), the Net Proceeds of such
            sale or other disposition are applied in accordance with the
            applicable provisions of this Indenture.

            In case of any such consolidation, merger, sale or conveyance and
upon the assumption by the successor Person, by supplemental indenture, executed
and delivered to the Trustee, of the Note Guarantee and the due and punctual
performance of all of the covenants and conditions of this Indenture to be
performed by the Guarantor, such successor Person will succeed to and be
substituted for the Guarantor with the same effect as if it had been named
herein as a Guarantor. All the Note Guarantees so issued will in all respects
have the same legal rank and benefit under this Indenture as the Note Guarantees
theretofore and thereafter issued in accordance with the terms of this Indenture
as though all of such Note Guarantees had been issued at the date of the
execution hereof.

            Except as set forth in Articles 4 and 5 hereof, and notwithstanding
clauses 2(a) and (b) above, nothing contained in this Indenture or in any of the
Notes will prevent any consolidation or merger of a Guarantor with or into the
Company or another Guarantor, or will prevent any sale or conveyance of the
property of a Guarantor as an entirety or substantially as an entirety to the
Company or another Guarantor.

Section 11.05 Releases.

            The Note Guarantee of a Guarantor will be released:

            (1) in connection with any sale, disposition or transfer of all or
      substantially all of the assets of that Guarantor (including by way of
      merger or consolidation) to a Person that is not (either before or after
      giving effect to such transaction) the Company or

                                      -108-

<PAGE>

      a Restricted Subsidiary of the Company, if the sale, disposition or
      transfer does not violate the first paragraph of Section 4.10 hereof;

            (2) in connection with any sale, disposition or transfer of all of
      the Capital Stock of that Guarantor to a Person that is not (either before
      or after giving effect to such transaction) the Company or a Restricted
      Subsidiary of the Company, if the sale, disposition or transfer does not
      violate the first paragraph of Section 4.10 hereof;

            (3) if the Company designates any Restricted Subsidiary that is a
      Guarantor to be an Unrestricted Subsidiary in accordance with the
      applicable provisions of this Indenture;

            (4) upon Legal Defeasance in accordance with Article 8 hereof or
      satisfaction and discharge of this Indenture in accordance with Article 12
      hereof; or

            (5) upon the release of such Guarantor's guarantee under the Credit
      Agreement or such other Indebtedness requiring such Guarantor to provide a
      Note Guarantee as provided in Section 4.17 hereof.

            Any Guarantor not released from its obligations under its Note
Guarantee as provided in this Section 11.05 will remain liable for the full
amount of principal of and interest and premium and Additional Interest, if any,
on the Notes and for the other obligations of any Guarantor under this Indenture
as provided in this Article 11.

Section 11.06 Subordination of Note Guarantee

            Payments under the Note Guarantees shall be subordinated to the
prior payment in full of all Senior Indebtedness of such Guarantor, including
Senior Indebtedness incurred after the date of this Indenture, on the same basis
as the payments by the Company on the Notes are subordinated to the prior
payment in full of Senior Indebtedness of the Company. For the purposes of the
foregoing sentence, the Trustee and the Holders shall have the right to receive
and/or retain payments by any of the Guarantors only at such times as they may
receive and/or retain payments in respect of the Notes pursuant to this
Indenture, including Article 10.

                                   ARTICLE 12

                           SATISFACTION AND DISCHARGE

Section 12.01 Satisfaction and Discharge.

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

                                      -109-

<PAGE>

            (1) either:

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

                  (b) all Notes that have not been delivered to the Trustee for
            cancellation have become due and payable by reason of the mailing of
            a notice of redemption or otherwise or will become due and payable
            within one year and the Company or any Guarantor has irrevocably
            deposited or caused to be deposited with the Trustee as trust funds
            in trust solely for the benefit of the Holders, cash in U.S.
            dollars, non-callable Government Securities, or a combination
            thereof, in such amounts as will be sufficient, without
            consideration of any reinvestment of interest, to pay and discharge
            the entire Indebtedness on the Notes not delivered to the Trustee
            for cancellation for principal, premium and Additional Interest, if
            any, and accrued interest to the date of maturity or redemption;

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

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

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

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

            Notwithstanding the satisfaction and discharge of this Indenture, if
money has been deposited with the Trustee pursuant to subclause (b) of clause
(1) of this Section 12.01, the provisions of Sections 12.02 and 8.06 hereof will
survive such satisfaction and discharge. In addition, nothing in this Section
12.01 will be deemed to discharge those provisions of Section 7.07 hereof, that,
by their terms, survive the satisfaction and discharge of this Indenture.

Section 12.02 Application of Trust Money.

            Subject to the provisions of Section 8.06 hereof, all money
deposited with the Trustee pursuant to Section 12.01 hereof shall be held in
trust and applied by it, in accordance with the provisions of the Notes and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium and
Additional Interest,

                                      -110-

if any) and interest for whose payment such money has been deposited with the
Trustee; but such money need not be segregated from other funds except to the
extent required by law.

            If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 12.01 hereof by reason of any
legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's and any Guarantor's obligations under this Indenture
and the Notes shall be revived and reinstated as though no deposit had occurred
pursuant to Section 12.01 hereof; provided that if the Company has made any
payment of principal of, premium or Additional Interest, if any, or interest on,
any Notes because of 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 or Government Securities held by the Trustee or Paying Agent.

                    7-3/8% Senior Subordinated Notes due 2014

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

            (1) INTEREST. Dresser-Rand Group Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at
7-3/8% per annum from October 29, 2004 until maturity and shall pay the
Additional Interest, if any, payable pursuant to Section 8 of the Registration
Rights Agreement referred to below. The Company will pay interest and Additional
Interest, if any, semi-annually in arrears on May 1 and November 1 of each year,
or if any such day is not a Business Day, on the next succeeding Business Day
(each, an "Interest Payment Date"). Interest on the Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been
paid, from October 29, 2004 until the principal hereof is due. The first
Interest Payment Date shall be May 1, 2005. The Company will pay interest on
overdue principal at the rate borne by the Notes, and it shall pay interest on
overdue installments of interest at the same rate to the extent lawful. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.

            (2) METHOD OF PAYMENT. The Company will pay interest on the Notes
(except defaulted interest) and Additional Interest, if any, to the Persons who
are registered Holders of Notes at the close of business on the April 15 or
October 15 next preceding the Interest Payment Date, even if such Notes are
canceled after such record date and on or before such Interest Payment Date,
except as provided in Section 2.12 of the Indenture with respect to defaulted
interest. If a Holder has given wire transfer instructions to the Paying Agent
on behalf of the Issuer, the Paying Agent will remit all principal, interest and
premium and Additional Interest, if any, on that Holder's Notes in accordance
with these instructions. All other payments on the Notes will be made by mailing
a check to the registered address of each Holder thereof. Such payment will be
in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts.

            (3) PAYING AGENT AND REGISTRAR. Initially, Citibank, N.A., as the
Trustee, will act as Paying Agent and Registrar. The Company may change any
Paying Agent or Registrar without notice to any Holder. The Company or any of
its Subsidiaries may act in any such capacity.

            (4) INDENTURE. The Company issued the Notes under an Indenture dated
as of October 29, 2004 (the "Indenture") among the Company, the Guarantors and
the Trustee. The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the TIA. Terms defined in the
Indenture and not defined herein have the meanings ascribed thereto in the
Indenture. The Notes are subject to all the terms and provisions of the
Indenture, and Holders are referred to the Indenture and the TIA for a statement
of such terms. To the extent any provision of this Note conflicts with the
express provisions of the Indenture, the provisions of the Indenture shall
govern and be controlling.

                                       A-5

<PAGE>

            The Notes are unsecured senior subordinated obligations of the
Company. This Note is one of the Initial Notes referred to in the Indenture. The
Notes include the Initial Notes, any Additional Notes and any Exchange Notes
issued in exchange for Initial Notes or Additional Notes pursuant to the
Indenture. The Initial Notes, any Additional Notes and any Exchange Notes are
treated as a single class of securities under the Indenture. The Indenture
imposes certain limitations on the ability of the Company and its Restricted
Subsidiaries to, among other things, make certain Investments and other
Restricted Payments, pay dividends and other distributions, incur Indebtedness,
enter into consensual restrictions upon the payment of certain dividends and
distributions by such Restricted Subsidiaries, issue or sell shares of capital
stock of the Company and such Restricted Subsidiaries, enter into or permit
certain transactions with Affiliates, create or Incur Liens and make asset
sales. The Indenture also imposes limitations on the ability of the Company and
each Guarantor to consolidate or merge with or into any other Person or convey,
transfer or lease all or substantially all of its property.

            To guarantee the due and punctual payment of the principal and
interest on the Notes and all other amounts payable by the Company under the
Indenture and the Notes when and as the same shall be due and payable, whether
at maturity, by acceleration or otherwise, according to the terms of the Notes
and the Indenture, the Guarantors have, jointly and severally, unconditionally
guaranteed the Obligations of the Company under the Notes on an unsecured senior
subordinated basis pursuant to the terms of the Indenture.

            (5) SUBORDINATION. The Notes, and the guarantees thereof, are
general senior subordinated unsecured obligations of the Company and the
Guarantors, subordinated in right of payment to the prior payment in full, in
cash or Cash Equivalents, of all Obligations due in respect of existing or
future Senior Indebtedness of the Company or a Guarantor, as applicable, as set
forth in Articles 10 and 11, respectively, of the Indenture. Each Holder by its
acceptance hereof agrees to be bound by such provisions and authorizes and
expressly directs the Trustee, on its behalf, to take such action as may be
necessary or appropriate to effectuate the subordination provided for in the
Indenture and appoints the Trustee its attorney-in-fact for such purposes.

            (6) OPTIONAL REDEMPTION.

            (a) Except as set forth in subparagraphs (b) and (c) of this
Paragraph 6, the Company will not have the option to redeem the Notes prior to

part of the Notes, upon not less than 30 nor more than 60 days' notice, at the
redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest and Additional Interest, if any, on the Notes
to be redeemed to, but not including, the applicable redemption date, if
redeemed during the twelve-month period beginning on November 1 of the years
indicated below, subject to the rights of Holders on the relevant record date to
receive interest on the relevant interest payment date:

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

            Unless the Company defaults in the payment of the redemption price,
interest will cease to accrue on the Notes or portions thereof called for
redemption on the applicable redemption date.

            (b) Notwithstanding the provisions of subparagraph (a) of this
Paragraph 6, at any time prior to November 1, 2007, the Company may on any one
or more occasions redeem up to 35% of the aggregate principal amount of Notes
issued under the Indenture (including any additional notes issued after the
Issue Date) at a redemption price of 107.375% of the principal amount thereof,
plus accrued and unpaid interest and Additional Interest, if any, to, but not
including the redemption date, with the net cash proceeds of one or more Equity

Notes issued under the Indenture (excluding Notes held by the Company and its
Subsidiaries) remains outstanding immediately after the occurrence of such
redemption and (2) that such redemption occurs within 180 days of the date of
the closing of such Equity Offering.

            (c) At any time prior to November 1, 2009, the Company may also
redeem all or a part of the Notes, upon not less than 30 nor more than 60 days'
prior notice mailed by first class mail to each Holder's registered address, at
a redemption price equal to 100% of the principal amount of Notes to be
redeemed, plus the Applicable Premium as of, and accrued and unpaid interest and
Additional Interest, if any, to, but not including, the date of redemption,
subject to the rights of Holders on the relevant record date to receive interest
due on the relevant interest payment date.

            (7) MANDATORY REDEMPTION. The Company is not required to make
mandatory redemption or sinking fund payments with respect to the Notes.

            (8) NOTICE OF REDEMPTION. Notice of redemption will be mailed by
first class mail at least 30 days but not more than 60 days before the
redemption date to each Holder whose Notes are to be redeemed at its registered
address, except that redemption notices may be mailed more than 60 days prior to
a redemption date if the notice is issued in connection with a defeasance of the
Notes or a satisfaction or discharge of the Indenture. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000. Unless the Company defaults in the payment of the redemption price,
interest will cease to accrue on the Notes or portions thereof called for
redemption on the applicable redemption date.

            (9) REPURCHASE AT THE OPTION OF HOLDER.

            (a) If there is a Change of Control, the Company will make an offer
(a "Change of Control Offer") to each Holder to repurchase all or any part
(equal to $1,000 or an

                                       A-7

<PAGE>

integral multiple of $1,000) of that Holder's Notes at a purchase price in cash
equal to 101% of the aggregate principal amount of Notes repurchased plus
accrued and unpaid interest and Additional Interest, if any, on the Notes
repurchased to, but not including, the date of purchase, subject to the rights
of Holders on the relevant record date to receive interest due on the relevant
interest payment date. Within 30 days following any Change of Control, the
Company will mail a notice to each Holder setting forth the procedures governing
the Change of Control Offer as required by the Indenture.

            (b) If the Company or a Restricted Subsidiary of the Company
consummates any Asset Sales, within ten Business Days of each date on which the
aggregate amount of Excess Proceeds exceeds $15.0 million, the Company will
commence an offer to all Holders of Notes and all holders of other Indebtedness
that is pari passu with the Notes containing provisions similar to those set
forth in the Indenture with respect to offers to purchase or redeem with the
proceeds of sales of assets (an "Asset Sale Offer") pursuant to Section 4.10 of
the Indenture to purchase the maximum principal amount of Notes and such other
pari passu Indebtedness that may be purchased out of the Excess Proceeds at an
offer price in cash in an amount equal to 100% of the principal amount thereof
plus accrued and unpaid interest and Additional Interest, if any, thereon to,
but excluding, the date of purchase, in accordance with the procedures set forth
in the Indenture. To the extent that, any Excess Proceeds remain after the
consummation of an Asset Sale Offer, the Company may use those Excess Proceeds
for any purpose not otherwise prohibited by the Indenture. If the aggregate
principal amount of Notes and other pari passu Indebtedness tendered into such
Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes and such other pari passu Indebtedness to be purchased on a pro rata
basis. Holders of Notes that are the subject of an offer to purchase will
receive an Asset Sale Offer from the Company prior to any related purchase date
and may elect to have such Notes purchased by completing the form entitled
"Option of Holder to Elect Purchase" attached to the Notes.

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

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

            (12) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions, the Indenture or the Notes or the Note Guarantees may be amended or
supplemented with the consent of the Company and Holders of at least a majority
in aggregate principal amount of the then outstanding Notes, including
Additional Notes, if any, voting as a single

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 a Guarantor's obligations to Holders of the Notes
and Note Guarantees in case of a merger or consolidation or sale of all or
substantially all of the Company's or such Guarantor's assets, as applicable,
(iv) to make any change that would provide any additional rights or benefits to
the Holders or that does not adversely affect the legal rights under the
Indenture of any such Holder, (v) to comply with the requirements of the SEC in
order to effect or maintain the qualification of the Indenture under the TIA,
(vi) to conform the text of the Indenture or the Notes to any provision of the
"Description of the Notes" section of the Company's Offering Memorandum dated
October 14, 2004, to the extent that such provision in that "Description of the
Notes" was intended to be a verbatim recitation of a provision of the Indenture,
the Note Guarantees or the Notes, (vii) to provide for the issuance of
Additional Notes in accordance with the limitations set forth in the Indenture;

continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately. Notwithstanding the foregoing, in the case of an Event of
Default arising from certain events of bankruptcy or insolvency with respect to
the Company, any Restricted Subsidiary of the Company that is a Significant
Subsidiary or any group of Restricted Subsidiaries of the Company that, taken
together, would constitute a Significant Subsidiary, all outstanding Notes will
become due and payable immediately without further action or notice. Holders may
not enforce the Indenture or the Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in aggregate principal
amount of the then outstanding Notes may direct the Trustee in its exercise of
any trust or power. The Holders of a majority in aggregate principal amount of
the then outstanding Notes by notice to the Trustee may, on behalf of the
Holders of all of the Notes, rescind an acceleration or waive any existing
Default or Event of Default and its consequences under the Indenture except a
continuing Default or Event of Default in the payment of interest or premium or
Additional Interest, if any, on, or the principal of, the Notes. The Company is
required to deliver to the Trustee annually a statement regarding compliance
with the Indenture, and the Company is required, upon becoming aware of any
Default or Event of Default, to deliver to the Trustee a statement specifying
such Default or Event of Default.

            (14) DISCHARGE AND DEFEASANCE. Subject to certain conditions, the
Company at any time may terminate some or all of its obligations under the
Notes, the Note Guarantees and the Indenture if the Company deposits with the
Trustee money or Government Securities for the payment of principal of and
interest on the Notes to redemption or maturity, as the case may be.

            (15) 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.

            (16) NO RECOURSE AGAINST OTHERS. A director, manager, officer,
employee, incorporator, member or stockholder of the Company, any Parent or any
Subsidiary, as such, will not have any liability for any obligations of the
Company or the Guarantors under the Notes, the Note Guarantees or the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

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

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

and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts

            (19) ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes will have all the rights set forth in the Registration Rights
Agreement dated as of October 29, 2004, among the Company, the Guarantors and
the Placement Agents named therein or, in the case of Additional Notes, Holders
of Restricted Global Notes and Restricted Definitive Notes will have the rights
set forth in one or more registration rights agreements, if any, among the
Company, the Guarantors and the other parties thereto, relating to rights given

(collectively, the "Registration Rights Agreement").

            (20) 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.

is an institutional "accredited investor") as to each of which we exercise sole
investment discretion.

the several states of the United States.

            (c) In connection with the Registered Exchange Offer, the Issuers

      Business Days after the date notice thereof is mailed to the Holders (or,
      in each case, longer if required by applicable law);

            (iii) use their commercially reasonable efforts to keep the Exchange
      Offer Registration Statement continuously effective under the Act,
      supplemented and amended as required under the Act, to ensure that it is
      available for sales of New Securities by Exchanging Dealers during the
      Exchange Offer Registration Period;

            (iv) utilize the services of a depositary for the Registered
      Exchange Offer with an address in the Borough of Manhattan in New York
      City, which may be the Trustee, the New Securities Trustee or an Affiliate
      of either of them;

            (v) permit Holders to withdraw tendered Securities at any time prior
      to the close of business, New York time, on the last Business Day on which
      the Registered Exchange Offer is open;

            (vi) prior to effectiveness of the Exchange Offer Registration
      Statement, provide a supplemental letter to the Commission (A) stating
      that the Issuers are conducting the Registered Exchange Offer in reliance
      on the position of the Commission in Exxon Capital Holdings Corporation
      (pub. avail. May 13, 1988), Morgan Stanley & Co., Inc. (pub. avail. June
      5, 1991) and (B) including a representation that the Issuers have not
      entered into any arrangement or understanding with any person to
      distribute the New Securities to be received in the Registered Exchange
      Offer and that, to the best of

<PAGE>
                                      -6-

      the Issuers' information and belief, each Holder participating in the
      Registered Exchange Offer is acquiring the New Securities in the ordinary
      course of business and has no arrangement or understanding with any person
      to participate in the distribution of the New Securities; and

            (vii) comply in all respects with all laws applicable to the
      Registered Exchange Offer.

            (d) As soon as practicable after the close of the Registered
Exchange Offer, the Issuers shall:

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

            (ii) deliver to the Trustee for cancellation in accordance with
      Section 4(r) hereof all Securities so accepted for exchange; and

            (iii) cause the New Securities Trustee promptly to authenticate and
      deliver to each Holder of Securities a principal amount of New Securities
      equal to the principal amount of the Securities of such Holder so accepted
      for exchange.

            (e) Each Holder hereby acknowledges and agrees that any
Broker-Dealer and any such Holder using the Registered Exchange Offer to
participate in a distribution of the New Securities (x) could not under
Commission policy as in effect on the date of this Agreement rely on the
position of the Commission in Exxon Capital Holdings Corporation (pub. avail.
May 13, 1988) and Morgan Stanley & Co., Inc. (pub. avail. June 5, 1991), as
interpreted in the Commission's letter to Shearman & Sterling dated July 2, 1993
and similar no-action letters and (y) must comply with the registration and
prospectus delivery requirements of the Act in connection with any secondary
resale transaction, which must be covered by an effective registration statement
containing the selling security holder information required by Item 507 or 508,
as applicable, of Regulation S-K under the Act if the resales are of New
Securities obtained by such Holder in exchange for Securities acquired by such
Holder directly from any Issuer or any Affiliate of any Issuer. Accordingly,
each Holder participating in the Registered Exchange Offer shall be required to
represent to the Issuers that, at the time of the consummation of the Registered
Exchange Offer:

            (i) any New Securities received by such Holder shall be acquired in
      the ordinary course of business;

            (ii) such Holder shall have no arrangement or understanding with any
      person to participate in the distribution within the meaning of the Act of
      the Securities or the New Securities;

            (iii) such Holder is not an Affiliate of any Issuer; and

            (iv) if such Holder is an Exchanging Dealer, then such Holder will
      deliver a Prospectus in connection with a sale of any New Securities
      received by such Holder pursuant to the Registered Exchange Offer.

<PAGE>
                                      -7-

            (f) If any Placement Agent determines that it is not eligible to
participate in the Registered Exchange Offer with respect to the exchange of
Securities constituting any portion of an unsold allotment, at the request of
such Placement Agent, the Issuers shall issue and deliver to such Placement
Agent or the person purchasing New Securities registered under a Shelf
Registration Statement as contemplated by Section 3 hereof from such Placement
Agent, in exchange for such Securities, a like principal amount of New
Securities. The Issuers shall use their reasonable best efforts to cause the
CUSIP Service Bureau to issue the same CUSIP number and International Securities
Identification Number ("ISIN") for such New Securities as for New Securities
issued pursuant to the Registered Exchange Offer.

            3. Shelf Registration. (a) If (i) due to any change in law or
applicable interpretations thereof by the Commission's staff, the Issuers
determine upon advice of their outside counsel that they are not permitted to
effect the Registered Exchange Offer as contemplated by Section 2 hereof; (ii)
for any other reason the Registered Exchange Offer is not consummated within 300
days of the Closing Date; (iii) any Placement Agent so requests with respect to
Securities that are not eligible to be exchanged for New Securities in the
Registered Exchange Offer and that are held by it following consummation of the
Registered Exchange Offer; (iv) any Holder (other than a Placement Agent) is not
eligible to participate in the Registered Exchange Offer; or (v) in the case of
any Placement Agent that participates in the Registered Exchange Offer or
acquires New Securities pursuant to Section 2(f) hereof, such Placement Agent
does not receive freely tradeable New Securities in exchange for Securities
constituting any portion of an unsold allotment (it being understood that (x)
the requirement that a Placement Agent deliver a Prospectus containing the
information required by Item 507 or 508 of Regulation S-K under the Act in
connection with sales of New Securities acquired in exchange for such Securities
shall result in such New Securities being not "freely tradeable"; and (y) the
requirement that an Exchanging Dealer deliver a Prospectus in connection with
sales of New Securities acquired in the Registered Exchange Offer in exchange
for Securities acquired as a result of market-making activities or other trading
activities shall not result in such New Securities being not "freely
tradeable"), the Issuers shall file and use their commercially reasonable
efforts to cause to become and keep effective a Shelf Registration Statement in
accordance with subsection (b) below.

            (b) (i) The Issuers shall as promptly as practicable, but in no
event later than 210 days after such filing obligation arises, use their
commercially reasonable efforts to file with the Commission and shall use their
commercially reasonable efforts to cause to be declared effective under the Act
within 270 days after such filing obligation arises, a Shelf Registration
Statement relating to the offer and sale of the Securities or the New
Securities, as applicable, by the Holders thereof from time to time in
accordance with the methods of distribution elected by such Holders and set
forth in such Shelf Registration Statement; provided, however, that no Holder
(other than a Placement Agent) shall be entitled to have the Securities held by
it covered by such Shelf Registration Statement unless such Holder agrees in
writing to be bound by all of the provisions of this Agreement applicable to
such Holder; and provided further that with respect to New Securities received
by a Placement Agent in exchange for Securities constituting any portion of an
unsold allotment, the Issuers may, if permitted by current interpretations by
the Commission's staff, file a post-effective amendment to the Exchange Offer
Registration Statement containing the information required by Item 507 or 508 of
Regulation S-K, as applicable, in satisfaction of their obligations under this
subsection with respect thereto, and any

<PAGE>
                                      -8-

such Exchange Offer Registration Statement, as so amended, shall be referred to
herein as, and governed by the provisions herein applicable to, a Shelf
Registration Statement.

            (ii) The Issuers shall use their commercially reasonable efforts to
keep the Shelf Registration Statement continuously effective, supplemented and
amended as required by the Act, in order to permit the Prospectus forming part
thereof to be usable by Holders for a period from the date the Shelf
Registration Statement is declared effective by the Commission until the
earliest of: (A) the second anniversary of the Closing Date, (B) the date upon
which all the Securities or New Securities, as applicable, covered by the Shelf
Registration Statement have been sold pursuant to the Shelf Registration
Statement or (C) the date upon which the Securities or New Securities, as
applicable, covered by the Shelf Registration Statement become eligible for
resale, without regard to volume, manner of sale or other restrictions contained
in Rule 144 under the Act pursuant to paragraph (k) thereof (in any such case,
the "Shelf Registration Period"). The Issuers shall be deemed not to have used
their commercially reasonable efforts to keep the Shelf Registration Statement
effective during the Shelf Registration Period if they voluntarily take any
action that would result in Holders of Securities covered thereby not being able
to offer and sell such Securities at any time during the Shelf Registration
Period, unless such action is (x) required by applicable law or otherwise taken
by the Issuers in good faith and for valid business reasons (not including
avoidance of the Issuers' obligations hereunder), including the acquisition or
divestiture of assets and (y) permitted pursuant to Section 4(k)(ii) hereof.

            (iii) The Issuers shall cause the Shelf Registration Statement and
the related Prospectus and any amendment or supplement thereto, as of the
effective date of the Shelf Registration Statement or such amendment or
supplement, (A) to comply in all material respects with the applicable
requirements of the Act and (B) not to contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein (in the case of the
Prospectus, in the light of the circumstances under which they were made) not
misleading.

            4. Additional Registration Procedures. In connection with any Shelf
Registration Statement and, to the extent applicable, any Exchange Offer
Registration Statement, the following provisions shall apply.

            (a) The Issuers shall:

                  (i) furnish to counsel for the Representatives and to counsel

            Registration Statement and any Shelf Registration Statement, and
            each amendment thereof and each amendment or supplement, if any, to
            the Prospectus included therein (including all documents
            incorporated by reference therein after the initial filing) and
            shall use their commercially reasonable efforts to reflect in each
            such document, when so filed with the Commission, such comments as
            counsel to the Holders or counsel for the Representatives reasonably
            propose;

            D hereto in the letter of transmittal delivered pursuant to the
            Registered Exchange Offer;

                  (iii) if requested by a Placement Agent, include the
            information required by Item 507 or 508, as applicable, of
            Regulation S-K in the Prospectus contained in the Exchange Offer
            Registration Statement or Shelf Registration Statement; and

                  (iv) in the case of a Shelf Registration Statement, include
            the names of the Holders that propose to sell Securities pursuant to
            the Shelf Registration Statement as selling security holders.

            (b) The Issuers shall use their commercially reasonable efforts to
      ensure that:

                  (i) any Registration Statement and any amendment thereto and
            any Prospectus forming part thereof and any amendment or supplement
            thereto complies in all material respects with the Act; and

                  (ii) any Registration Statement and any amendment thereto does
            not, when it becomes effective, contain an untrue statement of a
            material fact or omit to state a material fact required to be stated
            therein or necessary to make the statements therein not misleading.

            (c) The Issuers shall advise the Representatives, the Holders of
      Securities covered by any Shelf Registration Statement and any Exchanging
      Dealer under any Exchange Offer Registration Statement that has provided
      in writing to the Issuers a telephone or facsimile number and address for
      notices, and, if requested by any Representative or any such Holder or
      Exchanging Dealer, shall confirm such advice in writing (which notice
      pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction
      to suspend the use of the Prospectus until the Issuers shall have remedied
      the basis for such suspension):

                  (i) when a Registration Statement and any amendment thereto
            has been filed with the Commission and when the Registration
            Statement or any post-effective amendment thereto has become
            effective;

                  (ii) of any request by the Commission after the effective date
            for any amendment or supplement to the Registration Statement or the
            Prospectus or for additional information;

                  (iii) of the issuance by the Commission of any stop order
            suspending the effectiveness of the Registration Statement or the
            institution of any proceeding for that purpose;

<PAGE>
                                      -10-

                  (iv) of the receipt by any Issuer of any notification with
            respect to the suspension of the qualification of the securities
            included therein for sale in any jurisdiction or the institution or
            threatening of any proceeding for such purpose; and

                  (v) of the happening of any event that requires any change in
            the Registration Statement or the Prospectus so that, as of such
            date, they (A) do not contain any untrue statement of a material
            fact and (B) do not omit to state a material fact required to be
            stated therein or necessary to make the statements therein (in the
            case of the Prospectus, in the light of the circumstances under
            which they were made) not misleading.

            (d) The Issuers shall use their commercially reasonable efforts to
      prevent the issuance of any order suspending the effectiveness of any
      Registration Statement or the qualification of the securities therein for
      sale in any jurisdiction and, if issued, to obtain as soon as possible the
      withdrawal thereof.

            (e) The Issuers shall furnish to each Holder of Securities covered
      by any Shelf Registration Statement, without charge, at least one (1) copy
      of such Shelf Registration Statement and any post-effective amendment
      thereto, including all material incorporated therein by reference, and, if
      the Holder so requests in writing, all exhibits thereto (including
      exhibits incorporated by reference therein).

            (f) The Issuers shall, during the Shelf Registration Period, deliver
      to each Holder of Securities covered by any Shelf Registration Statement,
      without charge, as many copies of the Prospectus (including the
      Preliminary Prospectus) included in such Shelf Registration Statement and
      any amendment or supplement thereto as such Holder may reasonably request.
      The Issuers consent to the use of the Prospectus or any amendment or
      supplement thereto by each of the selling Holders of Securities in
      connection with the offering and sale of the Securities covered by the
      Prospectus, or any amendment or supplement thereto, included in the Shelf
      Registration Statement.

            (g) The Issuers shall furnish to each Exchanging Dealer which so
      requests, without charge, at least one (1) conformed copy of the Exchange
      Offer Registration Statement and any post-effective amendments thereto,
      including all material incorporated by reference therein, and, if the
      Exchanging Dealer so requests in writing, all exhibits thereto (including
      exhibits incorporated by reference therein).

            (h) The Issuers shall promptly deliver to each Placement Agent, each
      Exchanging Dealer and each other person required to deliver a Prospectus
      during the Exchange Offer Registration Period, without charge, as many
      copies of the Prospectus included in such Exchange Offer Registration
      Statement and any amendments or supplements thereto as any such person may
      reasonably request. The Issuers consent to the use of the Prospectus or
      any amendments or supplements thereto by any Placement Agent, any
      Exchanging Dealer and any such other person that may be required to
      deliver a Prospectus following the Registered Exchange Offer in connection
      with the offering

<PAGE>
                                      -11-

      and sale of the New Securities covered by the Prospectus, or any amendment
      or supplement thereto, included in the Exchange Offer Registration
      Statement.

            (i) Prior to the Registered Exchange Offer or any other offering of
      Securities pursuant to any Registration Statement, the Issuers shall
      arrange, if necessary, for the registration or qualification of the
      Securities or the New Securities for sale under the laws of such
      jurisdictions as any Holder shall reasonably request and shall maintain
      such qualification in effect so long as required; provided that in no
      event shall any Issuer be obligated to qualify to do business in any
      jurisdiction where it is not then so qualified or to take any action that
      would subject it to service of process in suits, other than those arising
      out of the Initial Placement, the Registered Exchange Offer or any
      offering pursuant to a Shelf Registration Statement, in any such
      jurisdiction where it is not then so subject or to subject itself to
      taxation in excess of a nominal amount in respect of doing business in
      such jurisdiction.

            (j) The Issuers shall cooperate with the Holders of Securities to
      facilitate the timely preparation and delivery of certificates
      representing New Securities or Securities to be issued or sold pursuant to
      any Registration Statement free of any restrictive legends and in such
      denominations and registered in such names as Holders may request in
      writing at least three (3) Business Days prior to the closing date of any
      sales of New Securities.

            (k) (i) Upon the occurrence of any event contemplated by subsections
      (c) (ii) through (v) above, the Issuers shall promptly (or within the time
      period provided for by clause (ii) of this subsection (k), if applicable)
      prepare a post-effective amendment to the applicable Registration
      Statement or an amendment or supplement to the related Prospectus or file
      any other required document so that, as thereafter delivered to the
      Placement Agents of the Securities included therein, the Prospectus shall
      not include an untrue statement of a material fact or omit to state any
      material fact required to be stated therein or necessary to make the
      statements therein, in the light of the circumstances under which they
      were made, not misleading. In such circumstances, the period of
      effectiveness of the Exchange Offer Registration Statement provided for in
      Section 2 hereof shall be extended by the number of days from and
      including the date of the giving of a notice of suspension pursuant to
      Section 4(c) hereof to and including the date when the Placement Agents,
      the Holders of the Securities and any known Exchanging Dealer shall have
      received such amended or supplemented Prospectus pursuant to this Section
      4(k).

                  (ii) Upon the occurrence or existence of any pending corporate
            development or any other material event that, in the reasonable
            judgment of the Issuers, makes it appropriate to suspend the
            availability of a Shelf Registration Statement and the related
            Prospectus, the Issuers shall give notice (without notice of the
            nature or details of such events) to the Holders that the
            availability of the Shelf Registration is suspended and, upon actual
            receipt of any such notice, each Holder agrees not to sell any
            Registrable Securities pursuant to the Shelf Registration until such
            Holder's receipt of copies of the supplemented or amended Prospectus
            provided for in Section 3(a)(i) hereof, or until it is advised in
            writing

<PAGE>
                                      -12-

            by the Issuers that the Prospectus may be used, and has received
            copies of any additional or supplemental filings that are
            incorporated or deemed incorporated by reference in such Prospectus.
            The period during which the availability of the Shelf Registration
            and any Prospectus is suspended (the "Deferral Period") (1) shall
            not exceed 60 consecutive days, (2) shall not occur more than three
            (3) times during any calendar year and (3) shall extend the number
            of days the Shelf Registration or any Prospectus is required to be
            available by an amount equal to the Deferral Period. Any
            Registration Default Damages payable pursuant to Section 8(a)(iii)
            shall cease to accrue during any Deferral Period.

            (l) Not later than the effective date of any Registration Statement,
      the Issuers shall provide a CUSIP number and ISIN for the Securities or
      the New Securities, as the case may be, registered under such Registration
      Statement, and provide the Trustee with printed certificates for such
      Securities or New Securities, in a form eligible for deposit with The
      Depository Trust Company.

            (m) The Issuers shall comply in all material respects with all
      applicable rules and regulations of the Commission and shall make
      generally available to their security holders earnings statements
      satisfying the provisions of Section 11(a) of the Act as soon as
      practicable after the effective date of the applicable Registration
      Statement.

            (n) The Issuers shall cause the Indenture or any New Securities
      Indenture to be qualified under the Trust Indenture Act as required by
      applicable law in a timely manner.

            (o) The Issuers may require each Holder of Securities to be sold
      pursuant to any Shelf Registration Statement to furnish to the Issuers
      such information regarding the Holder and the distribution of such
      Securities as the Issuers may from time to time reasonably require for
      inclusion in such Registration Statement. The Issuers may exclude from
      such Shelf Registration Statement the Securities of any Holder that fails
      to furnish such information within a reasonable time after receiving such
      request.

            (p) In the case of any Shelf Registration Statement, upon the
      request of the Majority Holders, the Issuers shall enter into customary
      agreements (including, if requested, one underwriting agreement in
      customary form) and take all other appropriate actions, if any, as the
      Majority Holders shall reasonably request in order to expedite or
      facilitate the registration or the disposition of the Securities, and in
      connection therewith, if an underwriting agreement is entered into, cause
      the same to contain indemnification provisions and procedures no less
      favorable than those set forth in Section 6 hereof.

            (q) In the case of any Shelf Registration Statement, the Issuers
      shall:

                  (i) make reasonably available for inspection at a location
            where they are normally kept and during normal business hours by the
            Majority Holders of Securities to be registered thereunder, any
            underwriter participating in any disposition pursuant to such
            Registration Statement and any attorney, accountant or other agent
            retained by such Holders or any such underwriter all relevant

<PAGE>
                                      -13-

            financial and other records and pertinent corporate documents of the
            Issuers and their subsidiaries;

                  (ii) use its commercially reasonable efforts to cause its
            officers, directors, employees, accountants and auditors to supply
            all relevant information reasonably requested by the Holders or any
            such underwriter, attorney, accountant or agent (each, an
            "Inspector") in connection with any such Registration Statement as
            is customary for similar due diligence examinations; provided,
            however, that such Inspector shall first agree in writing with the
            Issuers that any information that is reasonably and in good faith
            designated by the Issuers in writing as confidential at the time of
            delivery of such information shall be kept confidential by such
            Inspector, unless (1) disclosure of such information is required by
            court or administrative order or is necessary to respond to
            inquiries of regulatory authorities, (2) disclosure of such
            information is required by law (including any disclosure
            requirements pursuant to federal securities laws in connection with
            the filing of such Registration Statement or the use of any
            Prospectus), (3) such information becomes generally available to the
            public other than as a result of a disclosure or failure to
            safeguard such information by such person or (4) such information
            becomes available to such Inspector from a source other than the
            Issuers and such source is not known, after due inquiry, by the
            relevant Holder to be bound by a confidentiality agreement or is not
            otherwise under a duty of trust to the Issuers;

                  (iii) make such representations and warranties to the Holders
            of Securities registered thereunder and the underwriters, if any, in
            form, substance and scope as are customarily made by issuers to
            underwriters in primary underwritten offerings;

                  (iv) obtain opinions of counsel to the Issuers and updates
            thereof (which counsel and opinions (in form, scope and substance)
            shall be reasonably satisfactory to the Managing Underwriters, if
            any) addressed to each selling Holder and the underwriters, if any,
            covering such matters as are customarily covered in opinions
            requested in underwritten offerings and such other matters as may be
            reasonably requested by such Holders and underwriters;

                  (v) obtain "comfort" letters and updates thereof from the
            independent certified public accountants of Holdings (and, if
            necessary, any other independent certified public accountants of any
            subsidiary of Holdings or of any business acquired by Holdings for
            which financial statements and financial data are, or are required
            to be, included in the Registration Statement), addressed to each
            selling Holder of Securities registered thereunder and the
            underwriters, if any, in customary form and covering matters of the
            type customarily covered in "comfort" letters in connection with
            primary underwritten offerings; and

                  (vi) deliver such documents and certificates as may be
            reasonably requested by the Majority Holders or the Managing
            Underwriters, if any, including those to evidence compliance with
            Section 4(k) hereof and with any

<PAGE>
                                      -14-

            customary conditions contained in the underwriting agreement or
            other agreement entered into by the Issuers.

            (r) If a Registered Exchange Offer is to be consummated, upon
      delivery of the Securities by Holders to the Company (or to such other
      person as directed by the Company) in exchange for the New Securities, the
      Company shall mark, or caused to be marked, on the Securities so exchanged
      that such Securities are being cancelled in exchange for the New
      Securities. In no event shall the Securities be marked as paid or
      otherwise satisfied.

            (s) The Issuers shall use their commercially reasonable best efforts
      to take all other steps necessary to effect the registration of the
      Securities or the New Securities, as the case may be, covered by a
      Registration Statement.

            5. Registration Expenses. The Issuers shall bear all expenses
incurred in connection with the performance of their obligations under Sections
2, 3 and 4 hereof and, in the event of any Shelf Registration Statement, shall
reimburse the Holders for the reasonable fees and disbursements of one firm or
counsel (which shall initially be Shearman & Sterling LLP, but which may be
another nationally recognized law firm experienced in securities matters
designated by the Majority Holders) to act as counsel for the Holders in
connection therewith, and, in the case of any Exchange Offer Registration
Statement, shall reimburse the Placement Agents for the reasonable fees and
disbursements of counsel acting in connection therewith, in each case which
counsel shall be approved by the Issuer (such approval not to be unreasonably
withheld). Each Holder shall pay all expenses of its counsel other than as set
forth in the preceding sentence, underwriting discounts and commissions and
transfer taxes, if any, relating to the sale or disposition of such Holder's
Securities or New Securities.

            6. Indemnification and Contribution. (a) The Issuers, jointly and
severally, agree to indemnify and hold harmless each Holder of Securities or New
Securities, as the case may be, covered by any Registration Statement, each
Placement Agent and, with respect to any Prospectus delivery as contemplated in
Section 4(h) hereof, each Exchanging Dealer, the directors, officers and
Affiliates of each such Holder, Placement Agent or Exchanging Dealer and each
person who controls any such Holder, Placement Agent or Exchanging Dealer within
the meaning of either the Act or the Exchange Act against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of them
may become subject under the Act, the Exchange Act or other federal or state
statutory law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in the Registration Statement as originally filed or in any
amendment thereof, or in any preliminary Prospectus or the Prospectus, or in any
amendment thereof or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein (in the case of any
preliminary Prospectus or the Prospectus, in the light of the circumstances
under which they were made) not misleading, and agree (subject to the
limitations set forth in the provisos to this sentence) to reimburse each such
indemnified party, as incurred, for any legal or other expenses reasonably
incurred by it in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Issuers will not
be liable in any such case to the

<PAGE>
                                      -15-

extent that any such loss, claim, damage or liability arises out of or is based
upon any such untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with written
information furnished to the Issuers by or on behalf of the party claiming
indemnification specifically for inclusion therein; provided further that with
respect to any such untrue statement or alleged untrue statement or omission or
alleged omission from any preliminary Prospectus, the indemnity agreement
contained in this paragraph (a) shall not inure to the benefit of any Holder,
Placement Agent or Exchanging Dealer or any of their respective directors,
officers and Affiliates or control persons, from whom such person asserting such
loss, claim, damage or liability purchased the New Securities concerned, to the
extent that both (i) a copy of the final Prospectus was not sent or given to
such person at or prior to the written confirmation of the sale of the
Securities or New Securities to such person and (ii) the untrue statement in or
omission from such preliminary Prospectus was corrected in the final Prospectus
unless, in either case, such failure to deliver the final Prospectus was a
result of non-compliance by the Issuer with the provisions of Section 4 hereof.
This indemnity agreement shall be in addition to any liability that the Issuers
may otherwise have. The Issuers shall not be liable under this Section 6 to any
indemnified party regarding any settlement or compromise or consent to the entry
of any judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
is consented to by the Issuers, which consent shall not be unreasonably
withheld.

            (b) Each Holder of securities covered by a Registration Statement
(including each Placement Agent that is a Holder, in such capacity) severally
and not jointly agrees to indemnify and hold harmless the Issuers, each of their
respective directors, each of their respective officers who sign such
Registration Statement and each person who controls any Issuer within the
meaning of either the Act or the Exchange Act, to the same extent as the
foregoing indemnity from the Issuers to each such Holder, but only with
reference to written information relating to such Holder furnished to the
Issuers by or on behalf of such Holder specifically for inclusion in the
documents referred to in the foregoing indemnity. This indemnity agreement will
be in addition to any liability that any such Holder may otherwise have.

            (c) Promptly after receipt by an indemnified party under this
Section 6 or notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section, notify the indemnifying party in writing of the commencement
thereof; but the failure to so notify the indemnifying party (i) will not
relieve it from liability under paragraph (a) or (b) above unless and to the
extent it did not otherwise learn of such action and such failure results in the
forfeiture by the indemnifying party of substantial rights and defenses; and
(ii) will not, in any event, relieve the indemnifying party from any obligations
to any indemnified party other than the indemnification obligation provided in
paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint
counsel (including local counsel) of the indemnifying party's choice at the
indemnifying party's expense to represent the indemnified party in any action
for which indemnification is sought (in which case the indemnifying party shall
not thereafter be responsible for the fees and expenses of any separate counsel,
other than local counsel if not appointed by the indemnifying party, retained by
the indemnified party or parties except as set forth below); provided, however,
that

<PAGE>
                                      -16-

such counsel shall be reasonably satisfactory to the indemnified party.
Notwithstanding the indemnifying party's election to appoint counsel (including
local counsel) to represent the indemnified party in an action, the indemnified
party shall have the right to employ separate counsel (including local counsel),
and the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest (based on the advice of counsel to the indemnified person); (ii) such
action includes both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded (based on the advice of
counsel to the indemnified person) that there may be legal defenses available to
it and/or other indemnified parties that are different from or additional to
those available to the indemnifying party; (iii) the indemnifying party shall
not have employed counsel reasonably satisfactory to the indemnified party to
represent the indemnified party within a reasonable time after notice of the
institution of such action; or (iv) the indemnifying party shall authorize the
indemnified party to employ separate counsel at the expense of the indemnifying
party. It is understood and agreed that the indemnifying party shall not, in
connection with any proceeding or related proceeding in the same jurisdiction,
be liable for the reasonable fees and expenses of more than one separate firm
(in addition to any local counsel) for all indemnified parties. Any such
separate firm for any Placement Agent, its directors, officers and Affiliates
and any control person shall be designated in writing by CGMI and any such
separate firm for any of the Issuers, its respective directors, officers and
Affiliates and any control person shall be designated in writing by the Company.
An indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding and does not include any
statement as to, or any concessions of, fault, culpability or failure to act by
or on behalf of any indemnified party.

            (d) In the event that the indemnity provided in paragraph (a) or (b)
of this Section is unavailable to or insufficient to hold harmless an
indemnified party for any reason, then each applicable indemnifying party shall
have a joint and several obligation to contribute to the aggregate losses,
claims, damages and liabilities (including legal or other expenses reasonably
incurred in connection with investigating or defending any loss, claim,
liability, damage or action) (collectively "Losses") to which such indemnified
party may be subject in such proportion as is appropriate to reflect the
relative benefits received by such indemnifying party, on the one hand, and such
indemnified party, on the other hand, from the Initial Placement and the
Registration Statement which resulted in such Losses; provided, however, that in
no case shall any Placement Agent be responsible, in the aggregate, for any
amount in excess of the purchase discount or commission applicable to such
Security, or in the case of a New Security, applicable to the Security that was
exchangeable into such New Security, as set forth in the Final Memorandum, nor
shall any underwriter be responsible for any amount in excess of the
underwriting discount or commission applicable to the securities purchased by
such underwriter under the Registration Statement which resulted in such Losses.
If the allocation provided by the immediately preceding sentence is unavailable
for any reason, the indemnifying party and the indemnified party shall
contribute in such proportion as is appropriate to reflect not only such

<PAGE>
                                      -17-

relative benefits but also the relative fault of such indemnifying party, on the
one hand, and such indemnified party, on the other hand, in connection with the
statements or omissions which resulted in such Losses as well as any other
relevant equitable considerations. Benefits received by the Issuers shall be
deemed to be equal to the total net proceeds from the Initial Placement (before
deducting expenses) as set forth in the Final Memorandum. Benefits received by
the Placement Agents shall be deemed to be equal to the total purchase discounts
and commissions as set forth on the cover page of the Final Memorandum, and
benefits received by any other Holders shall be deemed to be equal to the value
of receiving Securities or New Securities, as applicable, registered under the
Act. Benefits received by any underwriter shall be deemed to be equal to the
total underwriting discounts and commissions, as set forth on the cover page of
the Prospectus forming a part of the Registration Statement which resulted in
such Losses. Relative fault shall be determined by reference to, among other
things, whether any untrue or any alleged untrue statement of a material fact or
omission or alleged omission to state a material fact relates to information
provided by the indemnifying party, on the one hand, or by the indemnified
party, on the other hand, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission and any other equitable considerations appropriate
in the circumstances. The parties agree that it would not be just and equitable
if the amount of such contribution were determined by pro rata allocation (even
if the Holders were treated as one entity for such purpose) or any other method
of allocation which does not take account of the equitable considerations
referred to above. Notwithstanding the provisions of this paragraph (d), no
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section, each
person who controls a Holder within the meaning of either the Act or the
Exchange Act and each director, officer, employee and agent of such Holder shall
have the same rights to contribution as such Holder, and each person who
controls any Issuer within the meaning of either the Act or the Exchange Act,
each officer of any Issuer who shall have signed the Registration Statement and
each director of any Issuer shall have the same rights to contribution as the
Issuers, subject in each case to the applicable terms and conditions of this
paragraph (d).

            (e) The provisions of this Section will remain in full force and
effect, regardless of any investigation made by or on behalf of any Holder or
the Issuers or any of the indemnified persons referred to in this Section 6, and
will survive the sale by a Holder of securities covered by a Registration
Statement.

            7. Underwritten Registrations. (a) If any of the Securities or New
Securities, as the case may be, covered by any Shelf Registration Statement are
to be sold in an underwritten offering, the Managing Underwriters, if any, shall
be selected by the Majority Holders subject to the consent of the Issuer (which
shall not be unreasonably withheld), and the Holders of Securities or New
Securities covered by such Shelf Registration Statement shall be responsible for
all underwriting commissions and discounts.

            (b) No person may participate in any underwritten offering pursuant
to any Shelf Registration Statement, unless such person (i) agrees to sell such
person's Securities or New Securities, as the case may be, on the basis
reasonably provided in any underwriting arrangements approved by the persons
entitled hereunder to approve such arrangements and (ii) completes and executes
all questionnaires, powers of attorney, indemnities, underwriting

<PAGE>
                                      -18-

agreements and other documents reasonably required under the terms of such
underwriting arrangements.

            8. Registration Defaults. (a) If any of the following events shall
occur, then the Company shall pay liquidated damages (the "Registration Default
Damages") to the Holders of Securities in respect of the Securities as follows:

            (i) if (a) neither (x) the Registered Exchange Offer is completed
      within 300 days of the Closing Date, nor (y) if required, the Shelf
      Registration Statement is declared effective within 270 days of the date
      the filing obligation arises with respect to such Shelf Registration
      Statement, then Registration Default Damages shall accrue on the
      Registrable Securities at a rate of 0.25% per annum on the principal
      amount of such Registrable Securities for the first 90 days from and
      including such specified date and increasing by an additional 0.25% per
      annum at the beginning of each subsequent 90-day period thereafter;
      provided that Registration Default Damages in the aggregate under this
      Section 8 may not exceed 1.0% per annum of the principal amount of such
      Registrable Securities; or

            (ii) subject to the last sentence of Section 4(k)(ii) above, if the
      Shelf Registration Statement required by Section 3(a) of this Agreement
      has been declared effective but thereafter ceases to be effective at any
      time at which it is required to be effective under this Agreement and such
      failure to remain effective exists for more than 30 consecutive days or
      more than 60 days (whether or not consecutive) during the period for which
      the Shelf Registration Statement is required, then commencing on the 31st
      day or 61st day, as applicable, following the date on which such Shelf
      Registration Statement ceases to be effective, Registration Default
      Damages shall accrue on the Registrable Securities at a rate of 0.25% per
      annum of the principal amount of such Registrable Securities for the first
      90 days from and including such 31st day or 61st day, as applicable,
      following the date on which such Shelf Registration Statement ceases to be
      effective and increasing by an additional 0.25% per annum at the beginning
      of each subsequent 90-day period thereafter; provided that Registration
      Default Damages in the aggregate under this Section 8 may not exceed 1.0%
      per annum of the principal amount of such Registrable Securities;

provided, however, that upon (1) the completion of the Exchange Offer (in the
case of paragraph (i) above) and (2) the effectiveness of the Shelf Registration
Statement which had ceased to remain effective (in the case of paragraph (ii)
above), Registration Default Damages shall cease to accrue.

            (b) The Issuers shall notify the Trustee within one Business Day
after each and every date on which an event occurs in respect of which
Registration Default Damages are required to be paid and within one Business Day
after such Registration Default Damages cease to accrue. Any amounts of
Registration Default Damages due pursuant to paragraphs (i) or (ii) of this
Section 8(a) will be payable in cash on each interest payment date specified by
the Indenture to the record holder entitled to receive the interest payment to
be made on such date, commencing with the first such date occurring after any
such Registration Default Damages commences to accrue.

<PAGE>
                                      -19-

            (c) The parties hereto agree that the liquidated damages in the form
of Registration Default Damages provided for in this Section 8 constitute a
reasonable estimate of and are intended to constitute the sole damages payable
under this Agreement that will be suffered by Holders of Securities by reason of
the failure of (i) the Registered Exchange Offer to be completed; (ii) the Shelf
Registration Statement, if required hereby, to be declared effective, or (iii)
the Shelf Registration Statement to remain effective (and the prospectus
contained therein to remain usable), in each case to the extent required by this
Agreement.

            9. No Inconsistent Agreements. No Issuer has entered into, and each
Issuer agrees not to enter into, any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders herein or that
otherwise conflicts with the provisions hereof.

            10. Amendments and Waivers. The provisions of this Agreement may not
be amended, qualified, modified or supplemented, and waivers or consents to
departures from the provisions hereof may not be given, unless the Issuers have
obtained the written consent of the Holders of a majority of the aggregate
principal amount of the Registrable Securities outstanding; provided that, with
respect to any matter that directly or indirectly affects the rights and
obligations of any Placement Agent hereunder, the Issuers shall obtain the
written consent of each such Placement Agent against which such amendment,
qualification, supplement, waiver or consent is to be effective; provided
further that no amendment, qualification, supplement, waiver or consent with
respect to Section 8 hereof shall be effective as against any Holder of
Registered Securities unless consented to in writing by such Holder; and
provided further that the provisions of this Article 10 may not be amended,
qualified, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, unless the Issuers have obtained the
written consent of the Placement Agents and each Holder. Notwithstanding the
foregoing (except the foregoing provisos), a waiver or consent to depart from
the provisions hereof with respect to a matter that relates exclusively to the
rights of Holders whose Securities or New Securities, as the case may be, are
being sold pursuant to a Registration Statement and that does not directly or

counterclaim arising out of or relating to this Agreement.

            17. Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstances, is
held invalid, illegal or unenforceable in any respect for any reason, the

or affected thereby, it being intended that all of the rights and privileges of
the parties shall be enforceable to the fullest extent permitted by law.

            18. Securities Held by any Issuer, etc. Whenever the consent or
approval of Holders of a specified percentage of principal amount of Securities
or New Securities is required hereunder, Securities or New Securities, as
applicable, held by any Issuer or their Affiliates (other than subsequent
Holders of Securities or New Securities if such subsequent Holders are deemed to
be Affiliates solely by reason of their holdings of such Securities or New
Securities) shall not be counted in determining whether such consent or approval
was given by the Holders of such required percentage.

            Each broker-dealer that receives New Securities for its own account
pursuant to the Exchange Offer must acknowledge that it shall deliver a
prospectus in connection with any resale of such New Securities. The Letter of
Transmittal states that by so acknowledging and by delivering a Prospectus, a
broker-dealer shall not be deemed to admit that it is an "underwriter" within
the meaning of the Act. This prospectus, as it may be amended or supplemented
from time to time, may be used by a broker-dealer in connection with resales of
New Securities received in exchange for Securities where such Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities. The Issuers have agreed that, for a period of 180 days after
consummation of the Registered Exchange Offer, they shall make this Prospectus
available to any broker-dealer for use in connection with any such resale. See
"Plan of Distribution."

            Each broker-dealer that receives New Securities for its own account
in exchange for Securities, where such Securities were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it shall deliver a Prospectus in connection
with any resale of such New Securities. See "Plan of Distribution."

                                                                         ANNEX C

                              PLAN OF DISTRIBUTION

            Each broker-dealer that receives New Securities for its own account
pursuant to the Registered Exchange Offer must acknowledge that it will deliver
a Prospectus in connection with any resale of such New Securities. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of New Securities received in
exchange for Securities where such Securities were acquired as a result of
market-making activities or other trading activities. The Issuers have agreed
that, for a period of 180 days after the consummation of the Registered Exchange
Offer, they will make this Prospectus, as amended or supplemented, available to
any broker-dealer for use in connection with any such resale. In addition, until
__________, 20___, all dealers effecting transactions in the New Securities may
be required to deliver a Prospectus.

            The Issuers will not receive any proceeds from any sale of New
Securities by brokers-dealers. New Securities received by broker-dealers for
their own account pursuant to the Registered Exchange Offer may be sold from
time to time in one or more transactions in the over-the-counter market, in
negotiated transactions, through the writing of options on the New Securities or
a combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer and/or the purchasers of any such New
Securities. Any broker-dealer that resells New Securities that were received by
it for its own account pursuant to the Registered Exchange Offer and any broker
or dealer that participates in a distribution of such New Securities may be
deemed to be an "underwriter" within the meaning of the Act and any profit of
any such resale of New Securities and any commissions or concessions received by
any such persons may be deemed to be underwriting compensation under the Act.
The Letter of Transmittal states that by acknowledging that it will deliver and
by delivering a Prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Act.

            For a period of 180 days after the consummation of the Registered
Exchange Offer, the Issuers will promptly send additional copies of this
Prospectus and any amendments or supplements to this Prospectus to any
broker-dealer that requests such documents in the Letter of Transmittal. The
Issuers have agreed to pay all expenses incident to the Registered Exchange
Offer (including the expenses of one counsel for the holder of the Securities)
other than commissions or concessions of any brokers or dealers and will
indemnify the holders of the Securities (including any broker-dealers) against
certain liabilities, including liabilities under the Act.

            [If applicable, add information required by Regulation S-K Items 507
and/or 508.]

                LANGUAGE TO BE INCLUDED IN LETTER OF TRANSMITTAL

1.    PLEASE FILL IN YOUR NAME AND ADDRESS BELOW IF YOU ARE A BROKER-DEALER AND

2.    If the undersigned is not a Broker-Dealer, the undersigned represents that
      it acquired the New Securities in the ordinary course of its business, it
      is not engaged in, and does not intend to engage in, a distribution of New
      Securities and it has no arrangements or understandings with any person to
      participate in a distribution of the New Securities. If the undersigned is
      a Broker-Dealer that will receive New Securities for its own account in
      exchange for Securities, it represents that the Securities to be exchanged
      for New Securities were acquired by it as a result of market-making
      activities or other trading activities and acknowledges that it shall
      deliver a Prospectus in connection with any resale of such New Securities;
      however, by so acknowledging and by delivering a Prospectus, the
      undersigned shall not be deemed to admit that it is an "underwriter"
      within the meaning of the Act.
