          "Consolidated Coverage Ratio" as of any date of determination means
the ratio of:

          (x) the aggregate amount of EBITDA for the period of the most recent
     four consecutive fiscal quarters ending prior to the date of such

          (Y) Consolidated Interest Expense for such four fiscal quarters;

PROVIDED, HOWEVER, that:

          (1)     if the Company or any Restricted Subsidiary has Incurred any
     Indebtedness since the beginning of such period that remains outstanding or
     if the transaction giving rise to the need to calculate the Consolidated
     Coverage Ratio is an Incurrence of Indebtedness, or both, EBITDA and
     Consolidated Interest Expense for such period shall be calculated after
     giving effect on a pro forma basis to such Indebtedness as if such
     Indebtedness had been Incurred on the first day of such period (except
     that, in making such computation, the amount of Indebtedness under any
     revolving credit facility outstanding on the date of such calculation shall
     be computed based on (A) the average daily balance of such Indebtedness
     during such four fiscal quarters or such shorter period when such facility
     was outstanding or (B) if such facility was created after the end of such
     four fiscal quarters, the average balance of such Indebtedness during the
     period from the date of creation of such facility to the date of the
     computation),

          (2)     if the Company or any Restricted Subsidiary has repaid,
     repurchased, defeased or otherwise discharged any Indebtedness since the
     beginning of such period or if any Indebtedness is to be repaid,
     repurchased, defeased or otherwise discharged (in each case other than
     Indebtedness Incurred under any revolving credit facility unless such
     Indebtedness has been permanently repaid and has not been replaced) on the
     date of the transaction giving rise to the need to calculate the
     Consolidated Coverage Ratio, EBITDA and Consolidated Interest Expense for
     such period shall be calculated on a pro forma basis as if such discharge
     had occurred on the first day of such period and as if the Company or such
     Restricted Subsidiary has not earned the interest income actually earned
     during such period in respect of cash or Temporary Cash Investments used to
     repay, repurchase, defease or otherwise discharge such Indebtedness,

<Page>

                                                                              12

          (3)     if since the beginning of such period the Company or any
     Restricted Subsidiary shall have made any Asset Disposition, EBITDA for
     such period shall be reduced by an amount equal to EBITDA (if positive)
     directly attributable to the assets which are the subject of such Asset
     Disposition for such period, or increased by an amount equal to EBITDA (if
     negative), directly attributable thereto for such period and Consolidated
     Interest Expense for such period shall be reduced by an amount equal to the
     Consolidated Interest Expense directly attributable to any Indebtedness of
     the Company or any Restricted Subsidiary repaid, repurchased, defeased or
     otherwise discharged with respect to the Company and its continuing
     Restricted Subsidiaries in connection with such Asset Disposition for such
     period (or, if the Capital Stock of any Restricted Subsidiary is sold, the
     Consolidated Interest Expense for such period directly attributable to the
     Indebtedness of such Restricted Subsidiary to the extent the Company and
     its continuing Restricted Subsidiaries are no longer liable for such
     Indebtedness after such sale),

          (4)     if since the beginning of such period the Company or any
     Restricted Subsidiary (by merger or otherwise) shall have made an
     Investment in any Restricted Subsidiary (or any Person which becomes a
     Restricted Subsidiary) or an acquisition of assets, including any
     acquisition of assets occurring in connection with a transaction requiring
     a calculation to be made hereunder, which constitutes all or substantially
     all of an operating unit of a business, EBITDA and Consolidated Interest
     Expense for such period shall be calculated after giving pro forma effect
     thereto (including the Incurrence of any Indebtedness) as if such
     Investment or acquisition occurred on the first day of such period, and

          (5)     if since the beginning of such period any Person (that
     subsequently became a Restricted Subsidiary or was merged with or into the
     Company or any Restricted Subsidiary since the beginning of such period)
     shall have made any Asset Disposition, any Investment or acquisition of
     assets that would have required an adjustment pursuant to clause (3) or (4)
     above if made by the Company or a Restricted Subsidiary during such period,
     EBITDA and Consolidated Interest Expense for such period shall be
     calculated after giving pro forma effect thereto as if such Asset
     Disposition, Investment or acquisition occurred on the first day of such
     period.

For purposes of this definition, whenever pro forma effect is to be given to an
acquisition of assets, the amount of income or earnings relating thereto and the
amount of Consolidated Interest Expense

                                                                              13

associated with any Indebtedness Incurred in connection therewith, the pro forma
calculations shall be determined 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 date of determination had
been the applicable rate for the entire period (taking into account any Interest
Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement
has a remaining term in excess of 12 months).

          "Consolidated Interest Expense" means, for any period, the total
interest expense of the Company and its consolidated Restricted Subsidiaries,
PLUS, to the extent not included in such interest expense, and to the extent
incurred by the Company or its Restricted Subsidiaries, without duplication,

          (1)     interest expense attributable to capital leases and the
     interest expense attributable to leases constituting part of a
     Sale/Leaseback Transaction,

          (2)     amortization of debt discount and debt issuance cost,

          (3)     capitalized interest,

          (4)     non-cash interest expense,

          (5)     commissions, discounts and other fees and charges owed with
     respect to letters of credit and bankers' acceptance financing,

          (6)     net payments pursuant to Hedging Obligations,

          (7)     dividends accrued in respect of all Preferred Stock held by
     Persons other than the Company or a Wholly Owned Subsidiary (other than
     dividends payable solely in Capital Stock (other than Disqualified Stock)
     of the Company); PROVIDED, HOWEVER, that such dividends shall be multiplied
     by a fraction the numerator of which is one and the denominator of which is
     one minus the effective combined income tax rate of the issuer of such
     Preferred Stock (expressed as a decimal) for such period (as estimated by
     the chief financial officer of the Company in good faith),

          (8)     interest incurred in connection with Investments in
     discontinued operations,

<Page>

                                                                              14

          (9)     interest accruing on any Indebtedness of any other Person to
     the extent such Indebtedness is Guaranteed by (or secured by the assets of)
     the Company or any Restricted Subsidiary, and

          (10)    the cash contributions to any employee stock ownership plan or
     similar trust to the extent such contributions are used by such plan or
     trust to pay interest or fees to any Person (other than the Company) in
     connection with Indebtedness Incurred by such plan or trust,

LESS, to the extent included in such total interest expense, the amortization
during such period of capitalized financing costs associated with the
acquisition by the Company of the Rexnord Group from Invensys plc.

          "Consolidated Net Income" means, for any period, the net income of the
Company and its consolidated Subsidiaries; PROVIDED, HOWEVER, that there shall
not be included in such Consolidated Net Income:

          (1)     any net income of any Person (other than the Company) if such
     Person is not a Restricted Subsidiary, except that

          (A) subject to the exclusion contained in clause (4) below, the
     Company's equity in the net income of any such Person for such period shall
     be included in such Consolidated Net Income up to the aggregate amount of
     cash actually distributed by such Person during such period to the Company
     or a Restricted Subsidiary as a dividend or other distribution (subject, in
     the case of a dividend or other distribution paid to a Restricted
     Subsidiary, to the limitations contained in clause (3) below), and

          (B) the Company's equity in a net loss of any such Person for such
     period shall be included in determining such Consolidated Net Income;

     Subsidiary is subject to restrictions, directly or indirectly, on the
     payment of dividends or the making of distributions by such Restricted
     Subsidiary, directly or

<Page>

                                                                              15

     indirectly, to the Company (but, in the case of any Foreign Subsidiary,
     only to the extent cash equal to such net income (or a portion thereof) for
     such period is not readily procurable by the Company from such Foreign

Trustee a copy of the 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 foregoing provisions.

                                    ARTICLE 2

                                 THE SECURITIES

          SECTION 2.01  FORM AND DATING. Provisions relating to the Securities
are set forth in the Rule 144A/Regulation S/IAI Appendix attached hereto (the
"Appendix"), which is hereby incorporated in and expressly made part of this
Indenture. The Securities and the Trustee's certificate of authentication shall
be substantially in the form of Exhibit 1 to the Appendix, which is hereby
incorporated in and expressly made a part of this Indenture. The Securities may
have notations, legends or endorsements required by law, stock exchange rule,
agreements to which the Company is subject, if any, or usage (PROVIDED that any
such notation, legend or endorsement is in a form acceptable to the Company).
Each Security shall be dated the date of its authentication. The terms of the
Securities set forth in the Appendix are part of the terms of this Indenture.

          SECTION 2.02  EXECUTION AND AUTHENTICATION. One Officer shall sign the
Securities for the Company by manual or facsimile signature.

<Page>

                                                                              40

          If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

          A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

          The Trustee shall authenticate and deliver Securities as set forth in
the Appendix.

          The Trustee may appoint an authenticating agent reasonably acceptable
to the Company to authenticate the Securities. Unless limited by the terms of
such appointment, an authenticating agent may authenticate Securities 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 any Registrar, Paying Agent or agent for service of notices and
demands.

          SECTION 2.03  REGISTRAR AND PAYING AGENT. The Company shall maintain
an office or agency where Securities may be presented for registration of
transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The Registrar
shall keep a register of the Securities and of their transfer and exchange. The
Company may have one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any additional paying agent. The
Company may change any Paying Agent or Registrar or co-registrar without notice
to any Holder.

          The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any Wholly Owned Subsidiary incorporated or organized within the
United States of America may act as Paying Agent, Registrar, co-registrar or
transfer agent.

<Page>

                                                                              41

          The Company initially appoints the Trustee as Registrar and Paying
Agent in connection with the Securities.

          SECTION 2.04  PAYING AGENT TO HOLD MONEY IN TRUST. On or prior to each
due date of the principal of and interest on any Security, the Company shall
deposit with the Paying Agent a sum sufficient to pay such principal and
interest when so becoming due. The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold in
trust for the benefit of Securityholders or the Trustee all money held by the
Paying Agent for the payment of principal of or interest on the Securities and
shall notify the Trustee of any default by the Company in making any such
payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate
the money held by it as Paying Agent and hold it as a separate trust fund. The
Company at any time may require a Paying Agent to pay all money held by it to
the Trustee and to account for any funds disbursed by the Paying Agent. Upon
complying with this Section 2.04, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

          SECTION 2.05  SECURITYHOLDER LISTS. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of all Securityholders and shall otherwise comply
with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall
furnish to the Trustee, in writing at least five Business Days before each
interest payment date and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of Securityholders.

          SECTION 2.06  TRANSFER AND EXCHANGE. The Securities shall be issued in
registered form and shall be transferable only upon the surrender of a Security
for registration of transfer. When a Security is presented to the Registrar or a
co-registrar with a request to register a transfer, the Registrar shall register
the transfer as requested if the requirements of this Indenture and Section
8-401(1) of the Uniform Commercial Code are met. When Securities are presented
to the Registrar or a co-registrar with a request to exchange them for an equal
principal amount of Securities of other denominations, the Registrar shall make
the exchange as requested if the same requirements are met.

          SECTION 2.07  REPLACEMENT SECURITIES. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall

<Page>

                                                                              42

authenticate a replacement Security if the requirements of Section 8-405 of the
Uniform Commercial Code are met and the Holder satisfies any other reasonable
requirements of the Trustee. If required by the Trustee or the Company, such
Holder shall furnish an indemnity bond sufficient in the judgment of the Company
and the Trustee to protect the Company, the Trustee, the Paying Agent, the
Registrar and any co-registrar from any loss which any of them may suffer if a
Security is replaced. The Company and the Trustee may charge the Holder for
their expenses in replacing a Security.

          Every replacement Security is an additional obligation of the Company.

          SECTION 2.08  OUTSTANDING SECURITIES. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancellation and those described in this
Section 2.08 as not outstanding. A Security does not cease to be outstanding
because the Company or an Affiliate of the Company holds the Security.

          If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

          If the Paying Agent segregates and holds in trust, in accordance with
this Indenture, on a redemption date or maturity date money sufficient to pay
all principal and interest payable on that date with respect to the Securities
(or portions thereof) to be redeemed or maturing, as the case may be, and the
Paying Agent is not prohibited from paying such money to the Securityholders on
that date pursuant to the terms of this Indenture, then on and after that date
such Securities (or portions thereof) cease to be outstanding and interest on
them ceases to accrue.

          SECTION 2.09  TEMPORARY SECURITIES. Until definitive Securities are
ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities and
deliver them in exchange for temporary Securities.

          SECTION 2.10  CANCELATION. The Company at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities

<Page>

                                                                              43

surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel and destroy (subject to the record
retention requirements of the Exchange Act) all Securities surrendered for
registration of transfer, exchange, payment or cancellation and deliver a
certificate of such destruction to the Company unless the Company directs the
Trustee to deliver canceled Securities to the Company. The Company may not issue
new Securities to replace Securities it has redeemed, paid or delivered to the
Trustee for cancellation.

          SECTION 2.11  DEFAULTED INTEREST. If the Company defaults in a payment
of interest on the Securities, the Company shall pay defaulted interest (plus
interest on such defaulted interest to the extent lawful) in any lawful manner.
The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date, the payment date
and the amount of defaulted interest to be paid.

          SECTION 2.12  CUSIP NUMBERS. The Company in issuing the Securities may
use numbers assigned by the Committee on Uniform Securities Identification
Procedures ("CUSIP") and corresponding International Securities Identification
Numbers ("ISIN") (if then generally in use) and, if so, the Trustee shall use
CUSIP numbers in notices of redemption as a convenience to Holders; PROVIDED,
HOWEVER, that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers. The Company shall
promptly notify the Trustee of any change in the CUSIP or ISIN numbers.

          SECTION 2.13  ADDITIONAL SECURITIES. The Company shall be entitled,
subject to its compliance with Section 4.03, to issue Additional Securities
under this Indenture which shall have identical terms as the Initial Securities
issued on the Issue Date, other than with respect to the date of issuance and
issue price. The Initial Securities issued on the Issue Date, any Additional
Securities and all Exchange Securities or Private Exchange Securities issued in
exchange therefor shall be treated as a single class for all purposes under this
Indenture.

<Page>

                                                                              44

          With respect to any Additional Securities, the Company shall set forth
in a resolution of the Board of Directors and an Officers' Certificate, a copy
of each which shall be delivered to the Trustee, the following information:

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

          (2)     the issue price, the issue date and the CUSIP number of such
     Additional Securities; PROVIDED, HOWEVER, that no Additional Securities may
     be issued at a price that would cause such Additional Securities to have
     "original issue discount" within the meaning of Section 1273 of the Code;
     and

          (3)     whether such Additional Securities shall be Transfer
     Restricted Securities and issued in the form of Securities as set forth in
     the Appendix to this Indenture or shall be issued in the form of Exchange
     Securities as set forth in Exhibit A.

                                    ARTICLE 3

                                   REDEMPTION

          SECTION 3.01  NOTICES TO TRUSTEE. If the Company elects to redeem
Securities pursuant to paragraph 5 of the Securities, it shall notify the
Trustee in writing of the redemption date, the principal amount of Securities to
be redeemed and the paragraph of the Securities pursuant to which the redemption
will occur.

          The Company shall give each notice to the Trustee provided for in this
Section 3.01 at least 30 days but not more than 60 days before the redemption
date unless the Trustee consents to a shorter period. Such notice shall be
accompanied by an Officers' Certificate from the Company to the effect that such
redemption will comply with the conditions herein.

          SECTION 3.02  SELECTION OF SECURITIES TO BE REDEEMED. If fewer than
all the Securities are to be redeemed, the Trustee shall select the Securities
to be redeemed pro rata or by lot or by a method that complies with applicable
legal and securities exchange requirements, if any, and that the Trustee in its
sole discretion shall deem to be fair and appropriate and in accordance with
methods generally used at the time of selection by fiduciaries in similar
circumstances. The Trustee shall make the selection from outstanding Securities
not previously called for redemption. The Trustee may select for redemption
portions of the principal of Securities that have denominations larger than
$1,000. Securities

<Page>

                                                                              45

and portions of them the Trustee selects shall be in principal amounts of $1,000
or a whole multiple of $1,000. Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called for
redemption. The Trustee shall notify the Company promptly of the Securities or
portions of Securities to be redeemed.

          SECTION 3.03  NOTICE OF REDEMPTION. At least 30 days but not more than
60 days before a date for redemption of Securities, the Company shall mail or
cause to be mailed a notice of redemption by first-class mail to each Holder of
Securities to be redeemed at such Holder's registered address.

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

          (1)     the redemption date;

          (2)     the redemption price;

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

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

          (5)     if fewer than all the outstanding Securities are to be
     redeemed, the identification and principal amounts of the particular
     Securities to be redeemed;

          (6)     that, unless the Company defaults in making such redemption
     payment or the Paying Agent is prohibited from making such payment pursuant
     to the terms of this Indenture, interest on Securities (or portion thereof)
     called for redemption ceases to accrue on and after the redemption date;
     and

          (7)     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 Securities.

          At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section 3.03.

          SECTION 3.04  EFFECT OF NOTICE OF REDEMPTION. Once notice of
redemption is mailed, Securities called for redemption

<Page>

                                                                              46

become due and payable on the redemption date and at the redemption price stated
in the notice. Upon surrender to the Paying Agent, such Securities shall be paid
at the redemption price stated in the notice, plus accrued interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the related interest payment date).
Failure to give notice or any defect in the notice to any Holder shall not
affect the validity of the notice to any other Holder.

          SECTION 3.05  DEPOSIT OF REDEMPTION PRICE. On or prior to the
redemption date, the Company shall deposit with the Trustee or the Paying Agent
(or, if the Company or a Subsidiary is the Trustee or the Paying Agent, shall
segregate and hold in trust) money sufficient to pay the redemption price of and
accrued interest on all Securities to be redeemed on that date other than
Securities or portions of Securities called for redemption which have been
delivered by the Company to the Trustee for cancellation. 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 on all Securities 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 Securities or the portions of the Securities called for redemption. If a
Security 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 Security was registered at the close of
business on such record date.

          SECTION 3.06  SECURITIES REDEEMED IN PART. Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee
shall authenticate for the Holder (at the Company's expense) a new Security
equal in principal amount to the unredeemed portion of the Security surrendered.

                                    ARTICLE 4

                                    COVENANTS

          SECTION 4.01  PAYMENT OF SECURITIES. The Company shall promptly pay or
cause to be paid the principal of and interest on the Securities on the dates
and in the manner provided in the Securities and in this Indenture. Principal
and interest shall be considered paid on the date due if on such date the
Trustee or the Paying Agent holds in accordance with this Indenture money
sufficient to pay all principal and interest then due and the

<Page>

     that such encumbrances or restrictions, taken as a whole, are no more
     restrictive in the aggregate than those contained in this Indenture, as
     determined in good faith by the Company's Board of Directors, whose
     determination shall be conclusive;

          (G) any encumbrance or restriction contained in any agreement or
     instrument governing Senior Indebtedness (including the Credit Agreement)
     not Incurred in violation of this Indenture; PROVIDED, HOWEVER, that such
     encumbrances or restrictions, taken as a whole, are no more restrictive in
     the aggregate than those contained in the Credit Agreement, as determined
     in good faith by the Company's Board of Directors, whose determination
     shall be conclusive;

          (H) with respect to any Restricted Subsidiary, any encumbrance or
     restriction contained in the terms of any Indebtedness, or any agreement
     pursuant to which such Indebtedness was issued, if:

                    (x) the encumbrance or restriction applies only in the event
               of a payment default or a default with respect to a financial
               covenant contained in such Indebtedness or agreement,

                    (y) the encumbrance or restriction is not materially more
               disadvantageous to the Secuityholders than is customary in
               comparable financings, as determined in good faith by the
               Company's Board of Directors, whose determination shall be
               conclusive, and

                    (z) such encumbrance or restriction will not materially
               affect the Company's ability to make principal or interest
               payments on the Securities, as determined in good faith by the
               Company's Board of Directors, whose determination shall be
               conclusive; and

          (I) imposed by customary provisions in joint venture agreements and
     similar agreements that restrict the transfer of the interest in the joint
     venture; and

          (2)     with respect to clause (c) only,

          (A) any encumbrance or restriction consisting of customary
     nonassignment provisions in leases governing leasehold interests or
     contracts to the extent such provisions restrict the transfer of the lease
     or the property leased thereunder or the contract; and

          (B) any encumbrance or restriction contained in security agreements or
     mortgages securing Indebtedness of a Restricted Subsidiary to the extent
     such encumbrance or restriction restricts the transfer of the property
     subject to such security agreements or mortgages.

          SECTION 4.06  LIMITATION ON SALES OF ASSETS AND SUBSIDIARY STOCK.

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

<Page>

                                                                              58

          (1)     the Company or such Restricted Subsidiary receives
     consideration at the time of such Asset Disposition at least equal to the
     fair market value (including as to the value of all non-cash
     consideration), as determined in good faith by the Board of Directors of
     the Company, of the shares and assets subject to such Asset Disposition;

          (2)     at least 75% of the consideration thereof received by the
     Company or such Restricted Subsidiary is in the form of cash or cash
     equivalents; and

          (3)     an amount equal to 100% of the Net Available Cash from such
     Asset Disposition is applied by the Company (or such Restricted Subsidiary,
     as the case may be)

          (A) FIRST, to the extent the Company elects (or is required by the
     terms of any Indebtedness), to prepay, repay, redeem or purchase Senior
     Indebtedness of the Company or a Subsidiary Guarantor or Indebtedness
     (other than any Disqualified Stock) of a Wholly Owned Subsidiary (in each
     case other than Indebtedness owed to the Company or an Affiliate (other
     than any Affiliate of the Company that is a lender under the Credit
     Agreement) of the Company) within one year from the later of the date of
     such Asset Disposition or the receipt of such Net Available Cash;

          (B) SECOND, to the extent of the balance of such Net Available Cash
     after application in accordance with Section 4.06(a)(3)(A), to the extent
     the Company elects, to acquire (or enter into a binding agreement to
     acquire, PROVIDED that such commitment shall be subject only to customary
     conditions (other than financing) and such acquisition shall be consummated
     within 90 days after the end of the one-year period referred to below)
     Additional Assets within one year from the later of the date of such Asset
     Disposition or the receipt of such Net Available Cash; and

          (C) THIRD, to the extent of the balance of such Net Available Cash
     after application in accordance with Section 4.06(a)(3)(A) and Section
     4.06(a)(3)(B), to make an Offer to the holders of the Securities (and to
     holders of other Senior Subordinated Indebtedness of the Company or a
     Subsidiary Guarantor designated by the Company) to purchase Securities (and
     such other Senior Subordinated Indebtedness of the Company or a Subsidiary
     Guarantor) pursuant to and subject to the conditions of Section 4.06(b);

<Page>

                                                                              59

          PROVIDED, HOWEVER, that in connection with any prepayment, repayment
          or purchase of Indebtedness pursuant to Section 4.06(a)(3)(A) or
          Section 4.06(a)(3)(C) above, the Company or such Restricted Subsidiary
          shall permanently retire such Indebtedness and shall cause the related
          loan commitment (if any) to be permanently reduced in an amount equal
          to the principal amount so prepaid, repaid or purchased.

          Notwithstanding the foregoing provisions of this Section 4.06, the
Company and the Restricted Subsidiaries shall not be required to apply any Net
Available Cash in accordance with this Section 4.06(a) except to the extent that
the aggregate Net Available Cash from all Asset Dispositions which is not
applied in accordance with this Section 4.06(a) exceeds $10.0 million. Pending
application of Net Available Cash pursuant to this Section 4.06(a), such Net
Available Cash shall be invested in Temporary Cash Investments or applied to
temporarily reduce revolving credit indebtedness.

          For the purposes of this Section 4.06(a), the following are deemed to
be cash or cash equivalents:

          (1)     the assumption of Indebtedness of the Company (other than
     obligations in respect of Disqualified Stock of the Company) or any
     Restricted Subsidiary (other than obligations in respect of Disqualified
     Stock or Preferred Stock of a Subsidiary Guarantor) and the release of the
     Company or such Restricted Subsidiary from all liability on such
     Indebtedness in connection with such Asset Disposition; and

          (2)     securities received by the Company or any Restricted
     Subsidiary from the transferee that are converted by the Company or such
     Restricted Subsidiary within 90 days into cash, to the extent of cash
     received in that conversion.

          (b)     In the event of an Asset Disposition that requires the
purchase of Securities (and other Senior Subordinated Indebtedness) pursuant to
Section 4.06(a)(3)(C), the Company shall purchase Securities tendered pursuant
to an offer by the Company for the Securities (and such other Senior
Subordinated Indebtedness) (the "Offer") at a purchase price of 100% of their
principal amount (or, if other than the Securities, 100% of their principal
amount or, in the event such other Senior Subordinated Indebtedness was issued
with significant original issue discount, 100% of the accreted value thereof),
without premium, plus accrued but unpaid interest (or, in respect of such other
Senior Subordinated Indebtedness, such lesser price, if any, as may be

<Page>

                                                                              60

provided for by the terms of such Senior Subordinated Indebtedness) in
accordance with the procedures (including prorationing in the event of
oversubscription) set forth in Section 4.06(c). If the aggregate purchase price
of Securities (and any other Senior Indebtedness Senior Subordinated
Indebtedness) tendered pursuant to the Offer exceeds the Net Available Cash
allotted to their purchase, the Company shall select the Securities and other
Senior Indebtedness Senior Subordinated Indebtedness to be purchased on a pro
rata basis but in round denominations, which in the case of the Securities will
be denominations of $1,000 principal amount or multiples thereof. The Company
shall not be required to make an Offer to purchase Securities (and other Senior
Subordinated Indebtedness) pursuant to this Section 4.06 if the Net Available
Cash available therefor is less than $10.0 million (which lesser amount shall be
carried forward for purposes of determining whether such an Offer is required
with respect to the Net Available Cash from any subsequent Asset Disposition).
Upon completion of an offer to purchase pursuant to Section 4.06, Net Available
Cash will be deemed to be reduced by the aggregate amount of such offer.

          (c)     (1) Promptly, and in any event within 10 days after the
     Company becomes obligated to make an Offer, the Company shall deliver to
     the Trustee and send, by first-class mail to each Holder, a written notice
     stating that the Holder may elect to have his Securities purchased by the
     Company either in whole or in part (subject to prorating as described in
     Section 4.06(b) in the event the Offer is oversubscribed) in integral
     multiples of $1,000 of principal amount, at the applicable purchase price.
     The notice shall specify a purchase date not less than 30 days nor more
     than 60 days after the date of such notice (the "Purchase Date") and shall
     contain such information concerning the business of the Company which the
     Company in good faith believes will enable such Holders to make an informed
     decision and all instructions and materials necessary to tender Securities
     pursuant to the Offer, together with the information contained in Section
     4.06(c)(3).

          (2)     Not later than the date upon which written notice of an Offer
     is delivered to the Trustee as provided below, the Company shall deliver to
     the Trustee an Officers' Certificate as to (A) the amount of the Offer (the
     "Offer Amount"), including information as to any other Senior Subordinated
     Indebtedness included in the Offer, (B) the allocation of the Net Available
     Cash from the Asset Dispositions pursuant to which such Offer is being made
     and (C) the compliance of such allocation with the provisions of Section
     4.06(a) and (b). On

                                                                              61

     such date, the Company shall also irrevocably deposit with the Trustee or
     with a Paying Agent (or, if the Company is acting as its own Paying Agent,
     segregate and hold in trust) in Temporary Cash Investments, maturing on the
     last day prior to the Purchase Date or on the Purchase Date if funds are
     immediately available by open of business, an amount equal to the Offer
     Amount to be held for payment in accordance with the provisions of this
     Section 4.06. If the Offer includes other Senior Subordinated Indebtedness,
     the deposit described in the preceding sentence may be made with any other
     paying agent pursuant to arrangements reasonably satisfactory to the
     Trustee. Upon the expiration of the period for which the Offer remains open
     (the "Offer Period"), the Company shall deliver to the Trustee for
     cancellation the Securities or portions thereof which have been properly
     tendered to and are to be accepted by the Company. The Trustee shall, on
     the Purchase Date, mail or deliver payment (or cause the delivery of
     payment) to each tendering Holder in the amount of the purchase price. In
     the event that the aggregate purchase price of the Securities delivered by
     the Company to the Trustee is less than the Offer Amount applicable to the
     Securities, the Trustee shall deliver the excess to the Company immediately
     after the expiration of the Offer Period for application in accordance with
     this Section 4.06.

          (3)     Holders electing to have a Security purchased shall be
     required to surrender the Security, with an appropriate form 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 telex, facsimile
     transmission or letter setting forth the name of the Holder, the principal
     amount of the Security which was delivered for purchase by the Holder and a
     statement that such Holder is withdrawing his election to have such
     Security purchased. Holders whose Securities are purchased only in part
     shall be issued new Securities equal in principal amount to the unpurchased
     portion of the Securities surrendered.

          (4)     At the time the Company delivers Securities to the Trustee
     which are to be accepted for purchase, the Company shall also deliver an
     Officers' Certificate stating that such Securities are to be accepted by
     the Company pursuant to and in accordance with the terms of this Section
     4.06. A Security shall be deemed to have been accepted for purchase at the
     time

<Page>

                                                                              62

     the Trustee, directly or through an agent, mails or delivers payment
     therefor to the surrendering Holder.

          (d)     The Company shall comply, to the extent applicable, with the
     requirements of Section 14(e) of the Exchange Act and any other securities
     laws or regulations in connection with the repurchase of Securities
     pursuant to this Section 4.06. To the extent that the provisions of any
     securities laws or regulations conflict with provisions of this Section
     4.06, the Company shall comply with the applicable securities laws and
     regulations and shall not be deemed to have breached its obligations under
     this Section 4.06 by virtue of its compliance with such securities laws or
     regulations.

          SECTION 4.07  LIMITATION ON AFFILIATE TRANSACTIONS.

          (a)     The Company shall not, and shall not permit any Restricted
     Subsidiary to, enter into or permit to exist any transaction (including the
     purchase, sale, lease or exchange of any property, employee compensation
     arrangements or the rendering of any service) with, or for the benefit of,
     any Affiliate of the Company (an "Affiliate Transaction") unless:

          (1)     the terms of the Affiliate Transaction are no less favorable
     to the Company or such Restricted Subsidiary than those that could be
     obtained at the time of the Affiliate Transaction in arm's-length dealings
     with a Person who is not an Affiliate;

          (2)     if such Affiliate Transaction involves an amount in excess of
     $5.0 million, the terms of the Affiliate Transaction are set forth in
     writing and a majority of the non-employee directors of the Company
     disinterested with respect to such Affiliate Transaction have determined in
     good faith that the criteria set forth in Section 4.07(a)(1) are satisfied
     and have approved the relevant Affiliate Transaction as evidenced by a
     resolution of such Board of Directors; and

          (3)     if such Affiliate Transaction involves an amount in excess of
     $25.0 million, the Board of Directors of the Company shall also have
     received a written opinion from an Independent Qualified Party to the
     effect that such Affiliate Transaction is fair, from a financial
     standpoint, to the Company and its Restricted Subsidiaries or is not less
     favorable to the Company and its Restricted Subsidiaries than could
     reasonably be expected to be obtained at the time in an arm's-length
     transaction with a Person who was not an Affiliate.

                                                                              63

          (b)     The provisions of Section 4.07(a) shall not prohibit

          (1)     any Investment or other Restricted Payment, in each case
     permitted to be made pursuant to Section 4.04;

          (2)     any issuance of securities, or other payments, awards or
     grants in cash, securities or otherwise pursuant to, or the funding of,
     employment arrangements, stock options and stock ownership plans approved
     by the Board of Directors of the Company;

          (3)     loans or advances to employees in the ordinary course of
     business in accordance with the past practices of the Company or its
     Restricted Subsidiaries, but in any event not to exceed $2.5 million in the
     aggregate outstanding at any one time;

          (4)     the payment of reasonable fees to directors of the Company and
     its Restricted Subsidiaries who are not employees of the Company or its
     Restricted Subsidiaries;

          (5)     any transaction with a Restricted Subsidiary or joint venture
     or similar entity which would constitute an Affiliate Transaction solely
     because the Company or a Restricted Subsidiary owns an equity interest in
     or otherwise controls such Restricted Subsidiary, joint venture or similar
     entity;

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

          (7)     the issuance or sale of any Capital Stock (other than
     Disqualified Stock) of the Company; and

          (8)     to the extent not restricted by other provisions of this
     Indenture, the pledge of Capital Stock of any Unrestricted Subsidiary to
     support Indebtedness of such Unrestricted Subsidiary.

          SECTION 4.08  LIMITATION ON THE SALE OR ISSUANCE OF CAPITAL STOCK OF
RESTRICTED SUBSIDIARIES. The Company (a) shall not, and shall not permit any
Restricted Subsidiary to, sell, lease, transfer or otherwise dispose of any
Capital Stock of any Restricted Subsidiary that is a Subsidiary as of the Issue
Date (or any successor in interest thereto) to any Person (other than the
Company or a Wholly Owned Subsidiary) and (b) shall not permit any Restricted
Subsidiary that is a Subsidiary as of the Issue Date (or any successor in
interest thereto) to issue any of its Capital

directors' or other legally required qualifying shares) to any Person (other
than to the Company or a Wholly Owned Subsidiary), unless (i) immediately after
giving effect to such issuance, sale or other disposition, neither the Company
nor any of its Subsidiaries own any Capital Stock of such Restricted Subsidiary
or (ii) immediately after giving effect to such issuance, sale or other
disposition, such Restricted Subsidiary would no longer constitute a Restricted
Subsidiary and any Investment in such Person remaining after giving effect
thereto is treated as a new Investment by the Company and such Investment would
be permitted to be made under Section 4.04 if made on the date of such issuance,
sale or other disposition.

          SECTION 4.09  CHANGE OF CONTROL.

          (a)     Upon the occurrence of a Change of Control, each Holder shall
have the right to require that the Company repurchase such Holder's Securities
at a purchase price in cash equal to 101% of the principal amount thereof on the
date of purchase plus accrued and unpaid interest, if any, to the date of
purchase (subject to the right of holders of record on the relevant record date
to receive interest due on the relevant interest payment date), in accordance
with the terms contemplated in Section 4.09(b). In the event that at the time of
such Change of Control the terms of any Senior Indebtedness of the Company
restrict or prohibit the purchase of Securities pursuant to this Section 4.09,
then prior to the mailing of the notice to Holders provided for in Section
4.09(b) below but in any event within 90 days following any Change of Control,
the Company shall (1) repay in full all such Senior Indebtedness or (2) obtain
the requisite consents under the agreements governing all such Senior
Indebtedness to permit the repurchase of the Securities as provided for in
Section 4.09(b).

          (b)     Within 30 days following any Change of Control, the Company
shall mail a notice to each Holder with a copy to the Trustee (the "Change of
Control Offer") stating:

          (1)     that a Change of Control has occurred and that such Holder has
     the right to require the Company to purchase such Holder's Securities at a
     purchase price in cash equal to 101% of the principal amount thereof on the
     date of purchase, plus accrued and unpaid interest, if any, to the date of
     purchase (subject to the right of Holders of record on the relevant record
     date to receive interest on the relevant interest payment date);

<Page>

                                                                              65

          (2)     the circumstances and relevant facts regarding such Change of

     cash flow and capitalization, in each case after giving effect to such
     Change of Control);

          (3)     the purchase date (which shall be no earlier than 30 days nor
     later than 60 days from the date such notice is mailed); and

          (4)     the instructions determined by the Company, consistent with
     this Section 4.09, that a Holder must follow in order to have its
     Securities purchased.

          (c)     Holders electing to have a Security purchased shall be
required to surrender the Security, with an appropriate form 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 Security which was
delivered for purchase by the Holder and a statement that such Holder is
withdrawing his election to have such Security purchased.

          (d)     On the purchase date, all Securities purchased by the Company
under this Section 4.09 shall be delivered by the Company to the Trustee for
cancellation, and the Company shall pay the purchase price plus accrued and
unpaid interest, if any, to the Holders entitled thereto.

          (e)     Notwithstanding the foregoing provisions of this Section 4.09,
the Company shall not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in Section 4.09(b) and purchases all Securities validly tendered and not
withdrawn under such Change of Control Offer.

          (f)     The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section 4.09. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.09, the Company shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations under this

Section 4.09 by virtue of its compliance with such securities laws or

Foreign Subsidiary that Guarantees Senior Indebtedness Incurred by another
Foreign Subsidiary) to, in each case, at the same time, execute and deliver to
the Trustee a Guaranty Agreement pursuant to which such Restricted Subsidiary
shall Guarantee payment of the Securities on the same terms and conditions as
those set forth in this Indenture.

          SECTION 4.12  COMPLIANCE CERTIFICATE. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company an
Officers' Certificate stating that in the course of the performance by the
signers of their duties as Officers of the Company they would normally have
knowledge of any Default and whether or not the signers know of any Default that
occurred during such period. If they do, the certificate shall describe the
Default, its status and what action the Company is taking or proposes to take
with respect thereto. The Company also shall comply with TIA Section 314(a)(4).

          SECTION 4.13  FURTHER INSTRUMENTS AND ACTS. Upon request of the
Trustee, the Company shall execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

          SECTION 5.01  WHEN COMPANY MAY MERGE OR TRANSFER ASSETS.

          (a)     The Company shall not consolidate with or merge with or into,
or convey, transfer or lease, in one transaction or a series of transactions,
directly or indirectly, all or substantially all its assets to, any Person,
unless:

          (1)     the resulting, surviving or transferee Person (the "Successor
     Company") shall be a Person organized and existing under the laws of the
     United States of America, any State

<Page>

                                                                              67

     thereof or the District of Columbia and the Successor Company (if not the
     Company) shall expressly assume, by an indenture supplemental hereto,
     executed and delivered to the Trustee, in form satisfactory to the Trustee,
     all the obligations of the Company under the Securities and this Indenture;

          (2)     immediately after giving pro forma effect to such transaction
     (and treating any Indebtedness which becomes an obligation of the Successor
     Company or any Subsidiary as a result of such transaction as having been
     Incurred by such Successor Company or such Subsidiary at the time of such
     transaction), no Default shall have occurred and be continuing;

          (3)     immediately after giving pro forma effect to such transaction,
     the Successor Company would be able to Incur an additional $1.00 of
     Indebtedness pursuant to Section 4.03(a); and

          (4)     the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that such
     consolidation, merger or transfer and such supplemental indenture (if any)
     comply with this Indenture.

PROVIDED, HOWEVER, that clause (3) shall not be applicable to (A) a Restricted
Subsidiary consolidating with, merging into or transferring all or part of its
properties and assets to the Company or (B) the Company merging with an
Affiliate of the Company solely for the purpose and with the sole effect of
reincorporating the Company in another jurisdiction.

          For purposes of this Section 5.01(a), the sale, lease, conveyance,
assignment, transfer or other disposition of all or substantially all of the
properties and assets of one or more Subsidiaries of the Company (other than to
the Company or any Restricted Subsidiary), which properties and assets, if held
by the Company instead of such Subsidiaries, would constitute all or
substantially all of the properties and assets of the Company on a consolidated
basis, shall be deemed to be the transfer of all or substantially all of the
properties and assets of the Company.

          The Successor Company shall be the successor to the Company and shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under this Indenture, and the predecessor Company, except in the
case of a lease, shall be released from the obligation to pay the principal of
and interest on the Securities.

          (b)     The Company shall not permit any Subsidiary Guarantor to
consolidate with or merge with or into, or convey, transfer or lease, in one
transaction or series of transactions, all or substantially all of its assets to
any Person unless:

          (1)     except in the case of a Subsidiary Guarantor (other than the
     Rexnord Operating Company and its successors in interest) that has been
     disposed of in its entirety to another Person (other than to the Company or
     a Subsidiary of the Company), whether through a merger, consolidation or
     sale of Capital Stock or assets, if in connection therewith the Company
     provides an Officers' Certificate to the Trustee to the effect that the
     Company will comply with its obligations under Section 4.06 in respect of
     such disposition, the resulting, surviving or transferee Person (if not
     such Subsidiary) shall be a Person organized and existing under the laws of
     the jurisdiction under which such Subsidiary was organized or under the
     laws of the United States of America, or any State thereof or the District
     of Columbia, and such Person shall expressly assume, by a Guaranty
     Agreement, in a form satisfactory to the Trustee, all the obligations of
     such Subsidiary, if any, under its Subsidiary Guaranty;

          (2)     immediately after giving effect to such transaction or
     transactions on a pro forma basis (and treating any Indebtedness which
     becomes an obligation of the resulting, surviving or transferee Person as a
     result of such transaction as having been issued by such Person at the time
     of such transaction), no Default shall have occurred and be continuing; and

          (3)     the Company delivers to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that such consolidation, merger or
     transfer and such Guaranty Agreement, if any, complies with this Indenture;

PROVIDED, HOWEVER, that Section 5.01(b) shall not be applicable to any
Subsidiary Guarantor that consolidates with, merges with or into or conveys,
transfers or leases all or substantially all of its assets to the Company or
another Subsidiary Guarantor.

          (c)     Pursuant to this Indenture, so long as the Parent Guaranty is
in effect, Parent agrees not to merge with or into, or convey, transfer or
lease, in one transaction or a series of transactions, all or substantially all
of its assets to any Person unless:

                                                                              69

          (1)     the resulting, surviving or transferee Person (if not Parent)
     shall be a Person organized and existing under the laws of the jurisdiction
     under which Parent was organized or under the laws of the United States of
     America, or any State thereof or the District of Columbia, and such Person
     shall expressly assume all the obligations of Parent, if any, under the
     Parent Guaranty;

          (2)     immediately after giving effect to such transaction or
     transactions on a pro forma basis (and treating any Indebtedness which
     becomes an obligation of the resulting, surviving or transferee Person as a
     result of such transaction as having been issued by such Person at the time
     of such transaction), no Default shall have occurred and be continuing; and

          (3)     the Company delivers to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that such consolidation, merger or
     transfer and such Guaranty Agreement, if any, complies with this Indenture.

                              DEFAULTS AND REMEDIES

          SECTION 6.01  EVENTS OF DEFAULT. An "Event of Default" occurs if:

     of 30 days;

          (2)     the Company (i) defaults in the payment of the principal of
     any Security when the same becomes due and payable at its Stated Maturity,

     whether or not such payment shall be prohibited by Article 10, or (ii)

<Page>

                                                                              70

          (5)     the Company or any Subsidiary Guarantor fails to comply with

     continues for 60 days after the notice specified below;

          (6)     Indebtedness of Parent (so long as the Parent Guaranty is in
     effect), the Company, any Subsidiary Guarantor or any Significant
     Subsidiary is not paid within any applicable grace period after final
     maturity or is accelerated by the holders thereof because of a default and
     the total amount of such Indebtedness unpaid or accelerated exceeds $20.0
     million;

          (7)     Parent (so long as the Parent Guaranty is in effect), the
     Company or any Significant Subsidiary pursuant to or within the meaning of
     any Bankruptcy Law:

                  (A) commences a voluntary case;

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

                  (C) consents to the appointment of a Custodian of it or for
          any substantial part of its property; or

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

     or takes any comparable action under any foreign laws relating to
     insolvency;

          (8)     a court of competent jurisdiction enters an order or decree

          an involuntary case;

                  (B) appoints a Custodian of Parent (so long as the Parent

<Page>

                                                                              71

                  (C) orders the winding up or liquidation of Parent (so long as
          the Parent Guaranty is in effect), the Company or any Significant
          Subsidiary;

     or any similar relief is granted under any foreign laws and the order or
     decree remains unstayed and in effect for 60 days;

          (9)     any judgment or decree for the payment of money (other than
     judgments that are covered by enforceable insurance policies issued by
     solvent carriers) in excess of $20.0 million is entered against Parent (so
     long as the Parent Guaranty is in effect), the Company or any Significant
     Subsidiary, remains outstanding for a period of 60 consecutive days
     following the entry of such judgment or decree and is not discharged,
     waived or the execution thereof stayed; or

          (10)    the Parent Guaranty or any Subsidiary Guaranty ceases to be in
     full force and effect (other than in accordance with the terms of the
     Parent Guaranty or such Subsidiary Guaranty or, in the case of a Subsidiary
     Guarantor that is not a Significant Subsidiary, other than as a result of
     bankruptcy) or Parent or any Subsidiary Guarantor denies or disaffirms its
     obligations under the Parent Guaranty or its Subsidiary Guaranty, as the
     case may be.

          The foregoing shall constitute Events of Default whatever the reason
for any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

          The term "Bankruptcy Law" means Title 11, UNITED STATES CODE, or any
similar Federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

          A Default under clause (4) or (5) is not an Event of Default until the
Trustee or the holders of at least 25% in principal amount of the outstanding
Securities notify the Company of the Default and the Company does not cure such
Default within the time specified after receipt of such notice. Such notice must
specify the Default, demand that it be remedied and state that such notice is a
"Notice of Default".

<Page>

                                                                              72

          The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default under clause (6) or (10) and any event which with the
giving of notice or the lapse of time would become an Event of Default under
clause (4) or (5) its status and what action the Company is taking or proposes
to take with respect thereto.

          SECTION 6.02  ACCELERATION. If an Event of Default (other than an
Event of Default specified in Section 6.01(7) or (8) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the Securities by notice to the
Company and the Trustee, may declare the principal of and accrued but unpaid
interest on all the Securities to be due and payable. Upon such a declaration,
such principal and interest shall be due and payable immediately, PROVIDED that
if any Designated Senior Indebtedness is outstanding at such time, neither the
Company nor any Guarantor shall make any payment with respect to the Securities
until five Business Days after the Representatives of all the issues of
Designated Senior Indebtedness receive written notice of such acceleration and,
thereafter, any such payment shall be made only if the provisions of Article 10
and 12 do not restrict payment at such time. If an Event of Default specified in
Section 6.01(7) or (8) with respect to the Company occurs, the principal of and
interest on all the Securities shall IPSO FACTO become and be immediately due
and payable without any declaration or other act on the part of the Trustee or
any Securityholders. The Holders of a majority in principal amount of the
Securities by notice to the Trustee may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of
acceleration. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

          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 of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Securityholder 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. No remedy is

<Page>

                                                                              73

exclusive of any other remedy. All available remedies are cumulative.

          SECTION 6.04  WAIVER OF PAST DEFAULTS. The Holders of a majority in
principal amount of the Securities by notice to the Trustee may waive an
existing Default and its consequences except (i) a Default in the payment of the
principal of or interest on a Security, (ii) a Default arising from the failure
to redeem or purchase any Security when required pursuant to this Indenture or
(iii) a Default in respect of a provision that under Section 9.02 cannot be
amended without the consent of each Securityholder affected. When a Default is
waived, it is deemed cured, but no such waiver shall extend to any subsequent or
other Default or impair any consequent right.

          SECTION 6.05  CONTROL BY MAJORITY. The Holders of a majority in
principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Trustee determines is unduly prejudicial to
the rights of other Securityholders or would involve the Trustee in personal
liability; PROVIDED, HOWEVER, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. Prior to
taking any action hereunder, the Trustee shall be entitled to indemnification
from such Holders satisfactory to it in its sole discretion against all losses
and expenses caused by taking or not taking such action.

          SECTION 6.06  LIMITATION ON SUITS. Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture or the
Securities unless:

          (1)     the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

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

          (3)     such Holder or Holders offer to the Trustee reasonable
     security or indemnity against any loss, liability or expense;

<Page>

                                                                              74

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

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

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

          SECTION 6.07  RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of principal of and interest on the Securities held by such Holder, on
or after the respective due dates expressed in the Securities, or to bring suit
for the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of such Holder.

          SECTION 6.08  COLLECTION SUIT BY TRUSTEE. If an Event of Default
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
7.07.

          SECTION 6.09  TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other
Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make 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 it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

          SECTION 6.10  PRIORITIES. If the Trustee collects any money or
property pursuant to this Article 6, it shall pay out the money or property in
the following order:

<Page>

                                                                              75

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

          SECOND: to holders of Senior Indebtedness of the Company and the
     Guarantors, to the extent required by Articles 10 and 12;

          THIRD:  to Securityholders for amounts due and unpaid on the
     Securities for principal and interest, ratably, without preference or
     priority of any kind, according to the amounts due and payable on the
     Securities for principal and interest, respectively; and

          FOURTH: to the Company.

          The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 6.10. At least 15 days before such
record date, the Company shall mail to each Securityholder and the Trustee a
notice that states the record date, the payment date and amount to be paid.

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

          SECTION 6.12  WAIVER OF STAY OR EXTENSION LAWS. The Company (to the
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution
of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law had been enacted.

                                     TRUSTEE

          SECTION 7.01  DUTIES OF TRUSTEE.

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

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

          (1)     the Trustee undertakes to perform such duties and only such
     duties as are specifically set forth in this Indenture and no implied
     covenants or obligations shall be read into this Indenture against the
     Trustee; and

          (2)     in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     the Trustee shall examine the certificates and opinions to determine
     whether or not they conform to the requirements of this Indenture.

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

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

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

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

          (d)     Every provision of this Indenture that in any way relates to
the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01.

<Page>

                                                                              77

          (e)     The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

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

          (g)     No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

          (h)     Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section 7.01 and to the provisions of the TIA.

          SECTION 7.02  RIGHTS OF TRUSTEE.

          (a)     The Trustee may rely on 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. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
the Officers' Certificate or Opinion of Counsel.

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

          (d)     The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers; PROVIDED, HOWEVER, that, without limiting the effect of
Section 7.01(b), the Trustee's conduct does not constitute wilful misconduct or
negligence.

          (e)     The Trustee may consult with counsel, and the advice or
opinion of counsel with respect to legal matters relating to this Indenture and
the Securities shall be full and complete authorization and protection from
liability in respect to any

<Page>

                                                                              78

action taken, omitted or suffered by it hereunder in good faith and in
accordance with the advice or opinion of such counsel.

          SECTION 7.03  INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar
or co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

          SECTION 7.04  TRUSTEE'S DISCLAIMER. The Trustee shall not be
responsible for and makes no representation, warranty or certification as to the
validity or adequacy of this Indenture or the Securities except as contained in
the Trustee's certificate of authentication. The Trustee shall not be
accountable for the Company's use of the proceeds from the issuance and sale of
the Securities and shall not be responsible for any statement of the Company,
any initial purchaser or placement agent or any other Person made in connection
with the issuance and sale of the Securities, whether oral or written and
whether contained in this Indenture, any offering document or any other
document, certificate or instrument.

          SECTION 7.05  NOTICE OF DEFAULTS. If a Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall mail to each
Securityholder notice of the Default within 90 days after it occurs. Except in
the case of a Default in payment of principal of or interest on any Security,
the Trustee may withhold the notice if and so long as a committee of its Trust
Officers in good faith determines that withholding the notice is in the
interests of Securityholders.

          SECTION 7.06  REPORTS BY TRUSTEE TO HOLDERS. As promptly as
practicable after each November 25 beginning with the November following the
date of this Indenture, and in any event prior to December 25 in each year for
so long as the Securities are outstanding, the Trustee shall mail to each
Securityholder a brief report dated as of November 25 that complies with TIA
Section 313(a). The Trustee also shall comply with TIA Section 313(b). The
Trustee will also transmit by mail all reports required by TIA Section 313(c).

          A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC and each stock exchange (if any) on which the
Securities are listed in accordance with TIA Section 313(d). The Company agrees
to notify promptly the Trustee whenever the Securities become listed on any
stock exchange and of any delisting thereof.

                                                                              79

          SECTION 7.07  COMPENSATION AND INDEMNITY. The Company shall pay to the
Trustee from time to time such reasonable compensation as agreed to between the
Company and the Trustee for its acceptance of the responsibilities under this
Indenture. The Trustee's compensation shall not be limited by any law on
compensation of a trustee of an express trust. The Company shall reimburse the
Trustee upon request for all reasonable disbursements, advancements and expenses
incurred or made by it, including costs of collection, in addition to the
compensation for its services. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee's agents,
counsel, accountants and experts. The Company shall indemnify the Trustee
against any and all loss, liability or expense (including reasonable attorneys'
fees) incurred by it in connection with the administration of this trust and the
performance of its duties hereunder. The Trustee shall notify the Company
promptly of any claim for which it may seek indemnity. Failure by the Trustee to
so notify the Company shall not relieve the Company of its obligations
hereunder. The Company shall defend the claim and the Trustee may have separate
counsel and the Company shall pay the reasonable fees and expenses of such
counsel. The Company need not pay for any settlement made without its consent,
which consent shall not be unreasonably withheld or delayed, nor reimburse any
expense nor indemnify against any loss, liability or expense incurred by the
Trustee through the Trustee's own wilful misconduct, negligence or bad faith.

          To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities. Such lien shall survive the
satisfaction and discharge of this Indenture.

          The Company's payment obligations pursuant to this Section 7.07 shall
survive the resignation and removal of the Trustee and the discharge of this
Indenture. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 6.01(7) or (8) with respect to the Company, the expenses
are intended to constitute expenses of administration under the Bankruptcy Law.

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

          SECTION 7.08 REPLACEMENT OF TRUSTEE. The Trustee may resign at any
time by so notifying the Company. The Holders of a majority in principal amount
of the Securities may remove the

<Page>

                                                                              80

Trustee by so notifying the Trustee and may appoint a successor Trustee. The
Company shall remove the Trustee if:

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

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

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

          (4)     the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns, is removed by the Company or by the Holders of
a majority in principal amount of the Securities and such Holders do not
reasonably promptly appoint a successor Trustee, or if a vacancy exists in the
office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Company shall promptly appoint a successor
Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

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

          If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

          Notwithstanding the replacement of the Trustee pursuant to this
Section 7.08, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

                                                                              81

          SECTION 7.09  SUCCESSOR TRUSTEE BY MERGER. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

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

          SECTION 7.10  ELIGIBILITY; DISQUALIFICATION. The Trustee shall at all
times satisfy the requirements of TIA Section 310(a). The Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
Section 310(b); PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Company are outstanding if the requirements for such exclusion set forth in
TIA Section 310(b)(1) are met.

          SECTION 7.11  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated.

                       DISCHARGE OF INDENTURE; DEFEASANCE

          SECTION 8.01  DISCHARGE OF LIABILITY ON SECURITIES; DEFEASANCE.

          (a)     When (1) the Company delivers to the Trustee all outstanding
Securities (other than Securities replaced pursuant to Section 2.07) for
cancellation or (2) all outstanding Securities

<Page>

                                                                              82

have become due and payable, whether at maturity or on a redemption date as a
result of the mailing of a notice of redemption pursuant to Article 3 hereof and
the Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity or upon redemption all outstanding Securities, including interest
thereon to maturity or such redemption date (other than Securities replaced
pursuant to Section 2.07), and if in either case the Company pays all other sums
payable hereunder by the Company, then this Indenture shall, subject to Section
8.01(c), cease to be of further effect. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Company.

          (b)     Subject to Sections 8.01(c) and 8.02, the Company at any time
may terminate (1) all its obligations under the Securities and this Indenture
("legal defeasance option") or (2) its obligations under Sections 4.02, 4.03,
4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10 and 4.11 and the operation of Sections
6.01(4), 6.01(6), 6.01(7), 6.01(8) and 6.01(9) (but, in the case of Sections
6.01(7) and (8), with respect only to Parent and Significant Subsidiaries) and
the limitations contain ed in Sections 5.01(a)(3) ("covenant defeasance
option"). The Company may exercise its legal defeasance option notwithstanding
its prior exercise of its covenant defeasance option.

          If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default with respect
thereto. If the Company exercises its covenant defeasance option, payment of the
Securities may not be accelerated because of an Event of Default specified in
Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8) and 6.01(9) (but, in the case of
Sections 6.01 (7) and (8), with respect only to Parent and Significant
Subsidiaries) or because of the failure of the Company to comply with Section
5.01(a)(3). If the Company exercises its legal defeasance option or its covenant
defeasance option, each Guarantor, if any, shall be released from all its
obligations with respect to its Guaranty.

          Upon satisfaction of the conditions set forth herein and upon request
of the Company, the Trustee shall acknowledge in writing the discharge of those
obligations that the Company terminates.

          (c)     Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and in
this Article 8 shall survive until the

<Page>

                                                                              83

Securities have been paid in full. Thereafter, the Company's obligations in
Sections 7.07, 8.04 and 8.05 shall survive.

          SECTION 8.02  CONDITIONS TO DEFEASANCE. The Company may exercise its
legal defeasance option or its covenant defeasance option only if:

          (1)     the Company irrevocably deposits in trust with the Trustee
     money or U.S. Government Obligations for the payment of principal of and
     interest on the Securities to maturity or redemption, as the case may be;

          (2)     the Company delivers to the Trustee a certificate from a
     nationally recognized firm of independent accountants expressing their
     opinion that the payments of principal and interest when due and without
     reinvestment on the deposited U.S. Government Obligations plus any
     deposited money without investment will provide cash at such times and in
     such amounts as will be sufficient to pay principal and interest when due
     on all the Securities to maturity or redemption, as the case may be;

          (3)     (A) the Company delivers to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Company with the
     intent of preferring the Holders over our other creditors with the intent
     of defeating, hindering, delaying or defrauding our other creditors and (B)
     in the case of legal defeasance only, 123 days pass after the deposit is
     made and during the 123-day period no Default specified in Sections 6.01(7)
     or (8) with respect to the Company occurs which is continuing at the end of
     the period;

          (4)     the deposit does not constitute a default under any other
     agreement binding on the Company and is not prohibited by Article 10 or 12;

          (5)     in the case of the legal defeasance option, the Company shall
     have delivered to the Trustee an Opinion of Counsel stating that (A) the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling or (B) since the date of this Indenture there has
     been a change in the applicable Federal income tax law, in either case to
     the effect that, and based thereon such Opinion of Counsel shall confirm
     that, the Securityholders will not recognize income, gain or loss for
     Federal income tax purposes as a result of such defeasance and will be
     subject to Federal income tax on the same amounts, in the same manner and
     at the

<Page>

                                                                              84

     same times as would have been the case if such defeasance had not occurred;

          (6)     in the case of the covenant defeasance option, the Company
     shall have delivered to the Trustee an Opinion of Counsel to the effect
     that the Securityholders 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; and

          (7)     the Company delivers to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent to
     the defeasance and discharge of the Securities as contemplated by this
     Article 8 have been complied with.

          Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article 3.

          SECTION 8.03  APPLICATION OF TRUST MONEY. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to (and in
accordance with the provisions of) this Article 8. It shall apply the deposited
money and the money from U.S. Government Obligations through the Paying Agent
and in accordance with this Indenture to the payment of principal of and
interest on the Securities. Money and securities so held in trust are not
subject to Article 10.

          SECTION 8.04  REPAYMENT TO COMPANY. The Trustee and the Paying Agent
shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

          Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Company upon request any money held by them for
the payment of principal or interest that remains unclaimed for two years, and,
thereafter, Securityholders entitled to the money must look to the Company for
payment as general creditors.

          SECTION 8.05  INDEMNITY FOR GOVERNMENT OBLIGATIONS. The Company shall
pay and shall indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against deposited U.S. Government Obligations or the principal
and interest received on such U.S. Government Obligations.

                                                                              85

          SECTION 8.06  REINSTATEMENT. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with this
Article 8 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 obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 8 until such time as the Trustee
or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article 8; PROVIDED, HOWEVER, that, if the
Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.

                                    ARTICLE 9

                                   AMENDMENTS

          SECTION 9.01  WITHOUT CONSENT OF HOLDERS. The Company, the Guarantors
and the Trustee may amend this Indenture or the Securities without notice to or
consent of any Securityholder:

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

          (2)     to comply with Article 5;

          (3)     to provide for uncertificated Securities in addition to or in
     place of certificated Securities; PROVIDED, HOWEVER, that the
     uncertificated Securities are issued in registered form for purposes of
     Section 163(f) of the Code or in a manner such that the uncertificated
     Securities are described in Section 163(f)(2)(B) of the Code;

          (4)     to add Guarantees with respect to the Securities, including
     any Subsidiary Guaranties, or to secure the Securities;

          (5)     to add to the covenants of the Company for the benefit of the
     Holders or to surrender any right or power herein conferred upon the
     Company, Parent or a Subsidiary Guarantor;

          (6)     to comply with any requirements of the SEC in connection with
     qualifying, or maintaining the qualification of, this Indenture under the
     TIA; or

<Page>

                                                                              86

          (7)     to make any change that does not adversely affect the rights
     of any Securityholder.

          An amendment under this Section 9.01 may not make any change that
adversely affects the rights under Article 10 or 12 of any holder of Senior
Indebtedness of the Company, Parent or a Subsidiary Guarantor then outstanding
unless the holders of such Senior Indebtedness (or any group or representative
thereof authorized to give a consent) consent to such change.

          After an amendment under this Section 9.01 becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment under this
Section 9.01.

          SECTION 9.02  WITH CONSENT OF HOLDERS. The Company, the Guarantors and
the Trustee may amend this Indenture or the Securities without notice to any
Securityholder but with the written consent of the Holders of at least a
majority in principal amount of the Securities then outstanding (including
consents obtained in connection with a tender offer or exchange for the
Securities) and, to the extent provided for in Section 6.04 and subject to
Section 6.07, waive any existing Default or Event of Default. However, without
the consent of each Securityholder affected thereby, an amendment may not:

          (1)     reduce the amount of Securities whose Holders must consent to
     an amendment;

          (2)     reduce the rate of or extend the time for payment of interest
     on any Security;

          (3)     reduce the principal amount of or extend the Stated Maturity
     of any Security;

          (4)     reduce the amount payable upon the redemption of any Security
     or change the time at which any Security may be redeemed in accordance with
     Article 3;

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

          (6)     impair the right of any Securityholder to receive payment of
     principal of and interest on such Holder's Securities on or after the due
     dates therefor or to institute suit for the enforcement of any payment on
     or with respect to such Holder's Securities;

<Page>

                                                                              87

          (7)     make any changes in the ranking or priority of any Security
     that would adversely affect the Securityholders;

          (8)     make any change in Section 6.04 or 6.07 or the second sentence
     of this Section 9.02; or

          (9)     make any change in, or release other than in accordance with
     Section 11.06 or 8.01(b), any Guaranty that would adversely affect the
     Securityholders.

          The obligation of the Company to make an offer to repurchase
Securities under Section 4.06 or 4.09 may be waived or modified with the written
consent of at least a majority in principal amount of the Securities then
outstanding (including consents obtained in connection with a tender offer or
exchange for the Securities), PROVIDED that any such waiver or modification will
apply only to a Change of Control or Asset Disposition occurring after the
effective date of such waiver or modification.

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

          An amendment under this Section 9.02 may not make any change that
adversely affects the rights under Article 10 or 12 of any holder of Senior
Indebtedness of the Company or of a Guarantor then outstanding unless the
holders of such Senior Indebtedness (or any group or representative thereof
authorized to give a consent) consent to such change.

          After an amendment under this Section 9.02 becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment under this
Section 9.02.

          SECTION 9.03  COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment to
this Indenture or the Securities shall comply with the TIA as then in effect.

          SECTION 9.04  REVOCATION AND EFFECT OF CONSENTS AND WAIVERS. A consent
to an amendment or a waiver by a Holder of a Security shall bind the Holder and
every subsequent Holder of that Security or portion of the Security that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent or waiver is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent or waiver as to such

Holder's Security or portion of the Security if the Trustee receives the notice
of revocation before the date the amendment or waiver becomes effective. After
an amendment or waiver becomes effective, it shall bind every Securityholder. An
amendment or waiver becomes effective upon the execution of such amendment or
waiver by the Trustee.

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

          SECTION 9.05  NOTATION ON OR EXCHANGE OF SECURITIES. If an amendment
or waiver changes the terms of a Security, the Trustee may require the Holder of
the Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

          SECTION 9.06  TRUSTEE TO SIGN AMENDMENTS. The Trustee shall sign any
amendment authorized pursuant to this Article 9 if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture.

          SECTION 9.07  PAYMENT FOR CONSENT. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is

                                                                              89

offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

                                   ARTICLE 10

                                  SUBORDINATION

          SECTION 10.01 AGREEMENT TO SUBORDINATE. The Company agrees, and each
Securityholder by accepting a Security agrees, that the Indebtedness and other
Obligations evidenced by the Securities is subordinated in right of payment, to
the extent and in the manner provided in this Article 10, to the prior payment
of all Obligations with respect to Senior Indebtedness of the Company (whether
outstanding on the Issue Date or thereafter incurred) and that the subordination
is for the benefit of and enforceable by the holders of such Senior
Indebtedness. The Securities shall in all respects rank PARI PASSU with all
other Senior Subordinated Indebtedness of the Company and only Indebtedness of
the Company which is Senior Indebtedness of the Company shall rank senior to the
Securities in accordance with the provisions set forth herein. All provisions of
this Article 10 shall be subject to Section 10.12.

          SECTION 10.02 LIQUIDATION, DISSOLUTION, BANKRUPTCY. (a) Upon any
payment or distribution of the assets of the Company of any kind or character,
whether in cash, property or securities, to creditors upon any total or partial
liquidation or any total or partial dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership, winding-up, assignment for
the benefit of creditors, marshalling of assets or similar proceeding relating
to the Company or its property, whether voluntary or involuntary:

          (1)     the holders of Senior Indebtedness of the Company shall be
     entitled to receive payment in full in cash of all Obligations with respect
     to all such Senior Indebtedness (including all interest accruing subsequent
     to the filing of a petition in bankruptcy at the rate provided for in the
     documentation with respect thereto, whether or not such interest is an
     allowed claim under applicable law) before Securityholders shall be
     entitled to receive any payment or distribution of any kind or character
     with respect to the Securities or for the acquisition of any Securities for
     cash, property or otherwise, except that Securityholders may receive
     Permitted Junior Securities and any Guarantee thereof permitted by the
     definition thereof; and

<Page>

                                                                              90

          (2)     until all such Senior Indebtedness is paid in full in cash,
     any payment or distribution to which Securityholders would be entitled but
     for this Article 10 shall be made to holders of such Senior Indebtedness as
     their interests may appear, except that Securityholders may receive
     Permitted Junior Securities and any Guarantee thereof permitted by the
     definition thereof.

          (b)     To the extent any payment of Senior Indebtedness of the
     Company (whether by or on behalf of the Company, as proceeds of security or
     enforcement of any right of setoff or otherwise) is declared to be
     fraudulent or preferential, set aside or required to be paid to any
     receiver, trustee in bankruptcy, liquidating trustee, agent or other
     similar Person under any bankruptcy, insolvency, receivership, fraudulent
     conveyance or similar law, then, if such payment is recovered by, or paid
     over to, such receiver, trustee in bankruptcy, liquidating trustee, agent
     or other similar Person, the Senior Indebtedness or part thereof originally
     intended to be satisfied shall be deemed to be reinstated and outstanding
     as if such payment had not occurred.

          SECTION 10.03 DEFAULT ON SENIOR INDEBTEDNESS OF THE COMPANY. The
Company shall not pay, nor shall it permit any Guarantor or other Subsidiary to
pay (in either case, in cash, property, securities or other assets), the
principal of, interest on or other Obligations owing with respect to the
Securities or make any deposit pursuant to Section 8.01 or 8.02 and may not
purchase, redeem or otherwise retire or acquire any Securities (collectively,
"pay the Securities") if either of the following (a "Payment Default") occurs
(1) any Obligations with respect to Senior Indebtedness of the Company are not
paid in full in cash when due or (2) any other default on Senior Indebtedness of
the Company occurs and the maturity of such Senior Indebtedness is accelerated
in accordance with its terms, unless, in either case, the Payment Default has
been cured or waived and any such acceleration has been rescinded or such Senior
Indebtedness has been paid in full in cash; PROVIDED, HOWEVER, that the Company
shall be entitled to pay the Securities without regard to the foregoing if the
Company and the Trustee receive written notice approving such payment from the
Representatives of all Senior Indebtedness with respect to which the Payment
Default has occurred and is continuing.

          During the continuance of any default (other than a Payment Default)
with respect to any Designated Senior Indebtedness of the Company pursuant to
which the maturity thereof may be accelerated immediately without further notice
(except such notice

<Page>

                                                                              91

as may be required to effect such acceleration) or the expiration of any
applicable grace periods (a "Non-Payment Default"), the Company shall not pay,
nor shall it permit any Guarantor or other Subsidiary to pay, the Securities for
a period (a "Payment Blockage Period") commencing upon the receipt by the
Trustee of written notice (a "Blockage Notice") of such default from the
Representative of such Designated Senior Indebtedness specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter. The Payment
Blockage Period shall end earlier if such Payment Blockage Period is terminated

          (1)     by written notice to the Trustee and the Company from the
     Person or Persons who gave such Blockage Notice;

          (2)     because the default giving rise to such Blockage Notice is
     cured, waived or otherwise no longer continuing and no other Non-Payment
     Default then exists with respect to such Designated Senior Indebtedness; or

          (3)     because such Designated Senior Indebtedness has been repaid in
     full in cash or otherwise has been satisfied in full to the satisfaction
     of, and with the consent of, the holders of such Designated Senior
     Indebtedness.

Notwithstanding the provisions described in the immediately preceding two
sentences (but subject to the provisions contained in the first sentence of this
Section 10.03), unless a Payment Default exists, the Company shall be entitled
to resume payments on the Securities after termination of such Payment Blockage
Period. The Securities shall not be subject to more than one Payment Blockage
Period in any consecutive 360-day period, irrespective of the number of defaults
with respect to Designated Senior Indebtedness of the Company during such
period; PROVIDED, HOWEVER, that if any Blockage Notice within such 360-day
period is given by or on behalf of any holders of Designated Senior Indebtedness
of the Company (other than the Bank Indebtedness), the Representative of the
Bank Indebtedness shall be entitled to give another Blockage Notice within such
period; PROVIDED FURTHER, HOWEVER, that in no event shall the total number of
days during which any Payment Blockage Period or Periods is in effect exceed 179
days in the aggregate during any 360 consecutive day period.

          For purposes of this Section 10.03, no default or event of default
which existed or was continuing on the date of the commencement of any Payment
Blockage Period with respect to the Designated Senior Indebtedness of the
Company initiating such Payment Blockage Period shall be, or be made, the basis
of the commencement of a subsequent Payment Blockage Period by the

<Page>

                                                                              92

Representative of such Designated Senior Indebtedness, whether or not within a
period of 360 consecutive days, unless such default or event of default shall
have been cured or waived for a period of not less than 90 consecutive days (it
being acknowledged that any subsequent action, or any breach of any financial
covenants for a period ending after the date of commencement of such Payment
Blockage Period that, in either case, would give rise to an event of default
pursuant to any provision under which an event of default previously existed or
was continuing shall constitute a new event of default for this purpose).

          SECTION 10.04 ACCELERATION OF PAYMENT OF SECURITIES. If payment of the
Securities is accelerated because of an Event of Default, the Company or the
Trustee shall promptly notify in writing the holders of the Designated Senior
Indebtedness of the Company (or their Representatives) of the acceleration
(although the failure to give any such notice shall not affect the
subordinations of this Article 10). If any Designated Senior Indebtedness of the
Company is outstanding, neither the Company nor any Guarantor shall pay the
Securities until five Business Days after the Representatives of all the issues
of Designated Senior Indebtedness of the Company receive written notice of such
acceleration and, thereafter, the Company and the Guarantors shall be entitled
to pay the Securities (and the Securityholders may accept and retain such
payment) only if this Article 10 otherwise permits payment (and the acceptance
and retention) at that time.

          SECTION 10.05 WHEN DISTRIBUTION MUST BE PAID OVER. If a distribution
or payment is made to (or received by) the Trustee or Securityholders that
because of this Article 10 should not have been made to (or received by) them,
the Trustee or Securityholders who receive the distribution or payment shall
hold it in trust for holders of Senior Indebtedness of the Company and pay it
over to them, as soon as reasonably practicable, as their interests may appear.

          SECTION 10.06 SUBROGATION. After all Senior Indebtedness of the
Company is paid in full in cash and until the Securities are paid in full,
Securityholders shall be subrogated to the rights of holders of Senior
Indebtedness to receive distributions applicable to such Senior Indebtedness. A
distribution made under this Article 10 to holders of Senior Indebtedness which
otherwise would have been made to Securityholders is not, as between the Company
and Securityholders, a payment by the Company on such Senior Indebtedness.

<Page>

                                                                              93

          SECTION 10.07 RELATIVE RIGHTS. This Article 10 defines the relative
rights of Securityholders and holders of Senior Indebtedness of the Company.
Nothing in this Indenture shall:

          (1)     impair, as between the Company and Securityholders, the
     obligation of the Company, which is absolute and unconditional, to pay
     principal of and interest on the Securities in accordance with their terms;
     or

          (2)     prevent the Trustee or any Securityholder from exercising its
     available remedies upon a Default, subject to the rights of holders of
     Senior Indebtedness of the Company to receive distributions or payments
     otherwise payable to Securityholders.

          SECTION 10.08 SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY OR HOLDERS
OF SENIOR INDEBTEDNESS. No right of any holder of Senior Indebtedness of the
Company to enforce the subordination of the Indebtedness and other Obligations
evidenced by the Securities shall be impaired or prejudiced by any act or
failure to act by the Company or any such holder or by the Company's failure to
comply with this Indenture, in each case regardless of any knowledge thereof
which any such holder may have or otherwise be charged with.

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Securityholders, without
incurring responsibility to the Trustee or the Securityholders and without
impairing or releasing the subordination provided in this Article 10 or the
obligations hereunder of the Trustee and the Securityholders to the holders of
Senior Indebtedness, do any one or more of the following: (1) change the manner,
place, terms or time of payment or extend the time of payment of, or renew or
alter, Senior Indebtedness or any instrument evidencing the same or any
agreement under which Senior Indebtedness is outstanding; (2) sell, exchange,
impair, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Indebtedness; (3) release any Person liable in any
manner for the collection or payment of Senior Indebtedness; and (4) exercise or
refrain from exercising any rights against the Company or any other Person.

          SECTION 10.09 RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding
Section 10.03, the Trustee or Paying Agent shall continue to make payments on
the Securities and shall not be charged with knowledge of the existence of facts
that under this Article 10 would prohibit the making of any such payments
unless,

<Page>

                                                                              94

not less than one Business Day (or if notice is received after 1:00 p.m., New
York City time, two Business Days) prior to the date of such payment, a Trust
Officer of the Trustee receives notice satisfactory to it that such payments are
prohibited by this Article 10. The Company, the Registrar or co-registrar, the
Paying Agent, a Representative or a holder of Senior Indebtedness of the Company
shall be entitled to give the notice; PROVIDED, HOWEVER, that, if an issue of
Senior Indebtedness of the Company has a Representative, only the Representative
shall be entitled to give the notice. Nothing in this Section 10.09 is intended
to or shall relieve any Securityholder from the obligations imposed under
Section 10.05 with respect to payments or distributions received (whether from
the Trustee or otherwise) in violation of the provisions hereof.

          The Trustee in its individual or any other capacity shall be entitled
to hold Senior Indebtedness of the Company with the same rights it would have if
it were not Trustee. The Registrar and co-registrar and the Paying Agent shall
be entitled to do the same with like rights. The Trustee shall be entitled to
all the rights set forth in this Article 10 with respect to any Senior
Indebtedness of the Company which may at any time be held by it, to the same
extent as any other holder of such Senior Indebtedness; and nothing in Article 7
shall deprive the Trustee of any of its rights as such holder. Nothing in this
Article 10 shall apply to claims of, or payments to, the Trustee (in its
capacity as such) under or pursuant to Section 7.07.

          SECTION 10.10 DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever any
Person is to make a distribution or give a notice to holders of Senior
Indebtedness of the Company, such Person shall be entitled to make such
distribution or give such notice to their Representative (if any).

          SECTION 10.11 ARTICLE 10 NOT TO PREVENT EVENTS OF DEFAULT OR LIMIT
RIGHT TO ACCELERATE. The failure to make a payment pursuant to the Securities by
reason of any provision in this Article 10 shall not be construed as preventing
the occurrence of a Default. Nothing in this Article 10 shall have any effect on
the right of the Securityholders or the Trustee to accelerate the maturity of
the Securities in accordance with Section 6.02.

          SECTION 10.12 TRUST MONEYS NOT SUBORDINATED. Notwithstanding anything
contained herein to the contrary, payments from money or the proceeds of U.S.
Government Obligations held in trust in accordance with Article 8 (and only so
long as all of the conditions to the deposit into such trust were satisfied at
the time of such deposit) by the Trustee for the payment of principal

<Page>

                                                                              95

of and interest on the Securities shall not be subordinated to the prior payment
of any Senior Indebtedness of the Company or subject to the restrictions set
forth in this Article 10, and none of the Securityholders shall be obligated to
pay over any such amount to the Company or any holder of Senior Indebtedness of
the Company or any other creditor of the Company.

          SECTION 10.13 TRUSTEE ENTITLED TO RELY. Upon any payment or
distribution pursuant to this Article 10, the Trustee and the Securityholders
shall be entitled to rely

          (1)     upon any order or decree of a court of competent jurisdiction
     in which any proceedings of the nature referred to in Section 10.02 are
     pending,

          (2)     upon a certificate of the liquidating trustee or agent or
     other Person making such payment or distribution to the Trustee or to the
     Securityholders or

          (3)     upon the Representatives of Senior Indebtedness of the Company

for the purpose of ascertaining the Persons entitled to participate in such
payment or distribution, the holders of such Senior Indebtedness and other
Indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article 10.

          In the event that the Trustee determines, in good faith, that evidence
is required with respect to the right of any Person as a holder of Senior
Indebtedness of the Company to participate in any payment or distribution
pursuant to this Article 10, the Trustee shall be entitled to request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the amount of such Senior Indebtedness held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and other
facts pertinent to the rights of such Person under this Article 10, and, if such
evidence is not furnished, the Trustee shall be entitled to defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment. The provisions of Sections 7.01 and 7.02 shall be
applicable to all actions or omissions of actions by the Trustee pursuant to
this Article 10.

          SECTION 10.14 TRUSTEE TO EFFECTUATE SUBORDINATION. Each Securityholder
by accepting a Security authorizes and directs the Trustee on its behalf to take
such action as may be necessary or

<Page>

                                                                              96

appropriate to acknowledge or effectuate the subordination between the
Securityholders and the holders of Senior Indebtedness of the Company as
provided in this Article 10 and appoints the Trustee as attorney-in-fact for any
and all such purposes.

          If neither the Trustee nor the Securityholders files a permitted claim
or proof of debt in the form required in any proceeding referred to in Section
6.01(7) or 6.01(8) prior to the tenth Business Day before the expiration of the
time to file such claim or claims, then any Representative of the holders of
Senior Indebtedness of the Company is hereby authorized to file such appropriate
claim for and on behalf of the Securityholders. Nothing herein contained shall
be deemed to authorize the Trustee or the holders of Senior Indebtedness of the
Company or their Representative to authorize or consent to or accept or adopt on
behalf of any Securityholder any plan of reorganization, arrangement, adjustment
or composition affecting the Securities or the rights of any Securityholder
thereof, or to authorize the Trustee or the holders of Senior Indebtedness of
the Company or their Representative to vote in respect of the claim of any
Securityholder in any such proceeding.

          SECTION 10.15 TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS
OF THE COMPANY. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness of the Company and shall not be liable to any
such holders if it shall mistakenly pay over or distribute to Securityholders or
the Company or any other Person, money or assets to which any holders of Senior
Indebtedness of the Company shall be entitled by virtue of this Article 10 or
otherwise.

          SECTION 10.16 RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS OF THE
COMPANY ON SUBORDINATION PROVISIONS. Each Securityholder by accepting a Security
(whether upon original issue or upon transfer, assignment or exchange thereof)
acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any Senior
Indebtedness of the Company, whether such Senior Indebtedness was created or
acquired before or after the issuance of the Securities, to acquire and continue
to hold, or to continue to hold, such Senior Indebtedness and such holder of
such Senior Indebtedness shall be deemed conclusively to have relied on such
subordination provisions in acquiring and continuing to hold, or in continuing
to hold, such Senior Indebtedness.

                                                                              97

                                   ARTICLE 11

                                   GUARANTIES

          SECTION 11.01 GUARANTIES. Each Guarantor hereby unconditionally and
irrevocably guarantees, jointly and severally, to each Holder and to the Trustee
and its successors and assigns (a) the full and punctual payment of principal of
and interest on the Securities when due, whether at maturity, by acceleration,
by redemption or otherwise, and all other monetary obligations of the Company
under this Indenture and the Securities and (b) the full and punctual
performance within applicable grace periods of all other obligations of the
Company under this Indenture and the Securities (all the foregoing being
hereinafter collectively called the "Securities Obligations"). Each Guarantor
further agrees that the Securities Obligations may be extended or renewed, in
whole or in part, without notice or further assent from such Guarantor and that
such Guarantor will remain bound under this Article 11 notwithstanding any
extension or renewal of any Securities Obligation.

          Each Guarantor waives presentation to, demand of, payment from and
protest to the Company of any of the Securities Obligations and also waives
notice of protest for nonpayment. Each Guarantor waives notice of any default
under the Securities or the Securities Obligations. The obligations of each
Guarantor hereunder shall not be affected by

          (a)     the failure of any Holder or the Trustee to assert any claim
     or demand or to enforce any right or remedy against the Company or any
     other Person under this Indenture, the Securities or any other agreement or
     otherwise;

          (b)     any extension or renewal of any such claim, demand, right or
     remedy;

          (c)     any rescission, waiver, amendment or modification of any of
     the terms or provisions of this Indenture, the Securities or any other
     agreement;

          (d)     the release of any security held by any Holder or the Trustee
     for the Securities Obligations or any of them;

          (e)     the failure of any Holder or the Trustee to exercise any right
     or remedy against any other guarantor of the Securities Obligations; or

<Page>

                                                                              98

          (f)     except as set forth in Section 11.06, any change in the
     ownership of such Guarantor.

          Each Guarantor further agrees that its Guaranty herein constitutes a
guarantee of payment, performance and compliance when due (and not a guarantee
of collection) and waives any right to require that any resort be had by any
Holder or the Trustee to any security held for payment of the Securities
Obligations.

          Each Guaranty is, to the extent and in the manner set forth in
Article 12, subordinated and subject in right of payment to the prior payment in
full of the principal of and premium, if any, interest on and all other
Obligations with respect to all Senior Indebtedness of the Guarantor giving such
Guaranty and each Guaranty is made subject to such provisions of this Indenture.

          Except as expressly set forth in Sections 8.01(b), 11.02 and 11.06,
the obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Securities Obligations or otherwise. Without limiting the generality of the
foregoing, the obligations of each Guarantor herein shall not be discharged or
impaired or otherwise affected by the failure of any Holder or the Trustee to
assert any claim or demand or to enforce any remedy under this Indenture, the
Securities or any other agreement, by any waiver or modification of any thereof,
by any default, failure or delay, willful or otherwise, in the performance of
the obligations, or by any other act or thing or omission or delay to do any
other act or thing which may or might in any manner or to any extent vary the
risk of such Guarantor or would otherwise operate as a discharge of such
Guarantor as a matter of law or equity.

          Each Guarantor further agrees that its Guarantee herein shall continue
to be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof, of principal of or interest on any Securities Obligation is
rescinded or must otherwise be restored by any Holder or the Trustee upon the
bankruptcy or reorganization of the Company or otherwise.

          In furtherance of the foregoing and not in limitation of any other
right which any Holder or the Trustee has at law or in equity against any
Guarantor by virtue hereof, upon the failure of the Company to pay the principal
of or interest on any Securities Obligation when and as the same shall become
due, whether at

                                                                              99

maturity, by acceleration, by redemption or otherwise, or to perform or comply
with any other Securities Obligation, each Guarantor hereby promises to and
shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to
be paid, in cash, to the Holders or the Trustee an amount equal to the sum of

          (1)     the unpaid amount of such Securities Obligations,

          (2)     accrued and unpaid interest on such Securities Obligations
     (but only to the extent not prohibited by law) and

          (3)     all other monetary Securities Obligations of the Company to
     the Holders and the Trustee.

          Each Guarantor agrees that it shall not be entitled to any right of
subrogation in respect of any Securities Obligations guaranteed hereby until
payment in full of all Securities Obligations and all obligations to which the
Securities Obligations are subordinated as provided in Article 12. Each
Guarantor further agrees that, as between it, on the one hand, and the Holders
and the Trustee, on the other hand,

          (x)     the maturity of the Securities Obligations Guaranteed hereby
     may be accelerated as provided in Article 6 for the purposes of such
     Guarantor's Guaranty herein, notwithstanding any stay, injunction or other
     prohibition preventing such acceleration in respect of the Securities
     Obligations guaranteed hereby, and

          (g)     in the event of any declaration of acceleration of such
     Securities Obligations as provided in Article 6, such Securities
     Obligations (whether or not due and payable) shall forthwith become due and
     payable by such Guarantor for the purposes of this Section 11.01.

          Each Guarantor also agrees to pay any and all costs and expenses
(including reasonable attorneys' fees) incurred by the Trustee or any Holder in
enforcing any rights under this Section 11.01.

          SECTION 11.02 LIMITATION ON LIABILITY. Any term or provision of this
Indenture to the contrary notwithstanding, the maximum aggregate amount of the
Securities Obligations guaranteed hereunder by any Guarantor shall not exceed
the maximum amount that can be hereby guaranteed without rendering this
Indenture, as it relates to such Guarantor, voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer or similar laws

<Page>

                                                                             100

affecting the rights of creditors generally, after giving effect to all Senior
Indebtedness of such Guarantor.

          SECTION 11.03 SUCCESSORS AND ASSIGNS. This Article 11 shall be binding
upon each Guarantor and its successors and assigns and shall enure to the
benefit of the successors and assigns of the Trustee and the Holders and, in the
event of any transfer or assignment of rights by any Holder or the Trustee, the
rights and privileges conferred upon that party in this Indenture and in the
Securities shall automatically extend to and be vested in such transferee or
assignee, all subject to the terms and conditions of this Indenture.

          SECTION 11.04 NO WAIVER. Neither a failure nor a delay on the part of
either the Trustee or the Holders in exercising any right, power or privilege
under this Article 11 shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article 11 at law,
in equity, by statute or otherwise.

          SECTION 11.05 MODIFICATION. No modification, amendment or waiver of
any provision of this Article 11, nor the consent to any departure by any
Guarantor therefrom, shall in any event be effective unless the same shall be in
writing and signed by the Trustee, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice to or demand on any Guarantor in any case shall entitle such Guarantor to
any other or further notice or demand in the same, similar or other
circumstances.

          SECTION 11.06 RELEASE OF GUARANTOR. (a) Upon

          (i) the sale (including any sale pursuant to any exercise of remedies
     by a holder of Senior Indebtedness of the Company or of such Subsidiary
     Guarantor) or other disposition (including by way of consolidation or
     merger) of a Subsidiary Guarantor,

          (ii) the sale or disposition of all or substantially all the assets of
     such Subsidiary Guarantor,

          (iii) upon the designation of such Subsidiary Guarantor as an
     Unrestricted Subsidiary pursuant to the terms of this Indenture or

<Page>

                                                                             101

          (iv) in connection with any sale of Capital Stock of a Subsidiary
     Guarantor to a Person in accordance with this Indenture that results in
     such Subsidiary Guarantor no longer being a Restricted Subsidiary (PROVIDED
     that after giving effect to such sale, such former Subsidiary Guarantor
     shall have no Guarantees outstanding of any Indebtedness of the Company or
     any Restricted Subsidiary),

such Subsidiary Guarantor shall be deemed released from all obligations under
this Article 11 without any further action required on the part of the Trustee
or any Holder, in each case other than a sale or disposition involving the
Rexnord Operating Company and other than a sale or disposition to the Company or
a Subsidiary of the Company. In the case of clauses (i), (ii) and (iv) above,
the Company shall provide an Officers' Certificate to the Trustee to the effect
that the Company will comply with its obligations under Section 4.06. At the
request of the Company, the Trustee shall execute and deliver an appropriate
instrument evidencing such release.

          (b)     If at any time following the Issue Date, Parent is no longer
     Guaranteeing any Indebtedness of the Company (other than the Securities) or
     any of the Restricted Subsidiaries, the Parent Guaranty shall be released
     upon presentation to the Trustee of an Officers' Certificate to the effect
     that no such Guarantees exist or are contemplated at such time. If Parent
     thereafter shall enter into any Guarantee of any Indebtedness of the
     Company or any of its Restricted Subsidiaries, Parent shall execute and
     deliver to the Trustee, at the same time such other Guarantee is provided,
     a Guaranty Agreement pursuant to which the Parent shall Guarantee payment
     of the Securities on the same terms and conditions as those set forth in
     this Indenture.

                                   ARTICLE 12

                           SUBORDINATION OF GUARANTIES

          SECTION 12.01 AGREEMENT TO SUBORDINATE. Each Guarantor agrees, and
each Securityholder by accepting a Security agrees, that the Indebtedness and
other Obligations evidenced by such Guarantor's Guaranty is subordinated in
right of payment, to the extent and in the manner provided in this Article 12,
to the prior payment of all Obligations with respect to Senior Indebtedness of
such Guarantor (whether outstanding on the Issue Date or thereafter incurred)
and that the subordination is for the benefit of and enforceable by the holders
of such Senior Indebtedness. The Securities Obligations of a Guarantor shall in
all respects rank

<Page>

                                                                             102

PARI PASSU with all other Senior Subordinated Indebtedness of such Guarantor and
only Senior Indebtedness of such Guarantor (including such Guarantor's Guarantee
of Senior Indebtedness of the Company) shall rank senior to the Securities
Obligations of such Guarantor in accordance with the provisions set forth
herein.

          SECTION 12.02 LIQUIDATION, DISSOLUTION, BANKRUPTCY. (a) Upon any
payment or distribution of the assets of any Guarantor of any kind or character,
whether in cash, property or securities, to creditors upon any total or partial
liquidation or any total or partial dissolution of such Guarantor or in a
bankruptcy, reorganization, insolvency, receivership, winding-up, assignment for
the benefit of creditors, marshalling of assets or similar proceeding relating
to such Guarantor or its property, whether voluntary or involuntary:

          (1)     the holders of Senior Indebtedness of such Guarantor shall be
     entitled to receive payment in full in cash of all Obligations with respect
     to all such Senior Indebtedness (including all interest accruing subsequent
     to the filing of a petition in bankruptcy at the rate provided for in the
     documentation with respect thereto, whether or not such interest is an
     allowed claim under applicable law) before Securityholders shall be
     entitled to receive any payment or distribution of any kind or character
     with respect to any Obligations of such Guarantor or for the acquisition of
     any Securities for cash, property or otherwise, except that Securityholders
     may receive Permitted Junior Securities and any Guarantee thereof permitted
     by the definition thereof; and

          (2)     until all the Senior Indebtedness of such Guarantor is paid in
     full in cash, any payment or distribution to which Securityholders would be
     entitled but for this Article 12 shall be made to holders of such Senior
     Indebtedness as their interests may appear, except that Securityholders may
     receive Permitted Junior Securities and any Guarantee thereof permitted by
     the definition thereof.

          (b)     To the extent any payment of Senior Indebtedness of any
     Guarantor (whether by or on behalf of the Company, as proceeds of security
     or enforcement of any right of setoff or otherwise) is declared to be
     fraudulent or preferential, set aside or required to be paid to any
     receiver, trustee in bankruptcy, liquidating trustee, agent or other
     similar Person under any bankruptcy, insolvency, receivership, fraudulent
     conveyance or similar law, then, if such payment is recovered by, or paid
     over to, such receiver, trustee in bankruptcy, liquidating trustee, agent
     or other similar Person, the Senior

<Page>

                                                                             103

     Indebtedness or part thereof originally intended to be satisfied shall be
     deemed to be reinstated and outstanding as if such payment had not
     occurred.

          SECTION 12.03 DEFAULT ON SENIOR INDEBTEDNESS OF GUARANTOR. No
Guarantor shall make any payment (in cash, property, securities or other assets)
with respect to its Guaranty or purchase, redeem or otherwise retire, acquire or
defease any Securities or other Securities Obligations (collectively, "pay its
Guaranty") if either of the following (a "Payment Default") occurs (1) any
Senior Indebtedness of such Guarantor or the Company is not paid in full in cash
when due or (2) any other default on Senior Indebtedness of such Guarantor or
the Company occurs and the maturity of such Senior Indebtedness is accelerated
in accordance with its terms, unless, in either case, the Payment Default has
been cured or waived and any such acceleration has been rescinded or such Senior
Indebtedness has been paid in full in cash; PROVIDED, HOWEVER, that any
Guarantor shall be entitled to make any payment with respect to its Guaranty
without regard to the foregoing if such Guarantor and the Trustee receive
written notice approving such payment from the Representatives of all Senior
Indebtedness with respect to which the Payment Default has occurred and is
continuing.

          During the continuance of any default (other than a Payment Default)
with respect to any Designated Senior Indebtedness of such Guarantor or the
Company pursuant to which the maturity thereof may be accelerated immediately
without further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods (a "Non-Payment
Default"), such Guarantor shall not pay its Guaranty for a period (a "Payment
Blockage Period") commencing upon the receipt by the Trustee of written notice
(a "Blockage Notice") of such default from the Representative of such Designated
Senior Indebtedness specifying an election to effect a Payment Blockage Period
and ending 179 days thereafter. The Payment Blockage Period shall end earlier if
such Payment Blockage Period is terminated

          (1)     by written notice to the Trustee and such Guarantor from the
     Person or Persons who gave such Blockage Notice;

          (2)     because the default giving rise to such Blockage Notice is
     cured, waived or otherwise no longer continuing and no other Non-Payment
     Default then exists with respect to such Designated Senior Indebtedness; or

          (3)     because such Designated Senior Indebtedness has been repaid in
     full in cash or otherwise has been satisfied in full

<Page>

                                                                             104

     to the satisfaction of, and with the consent of, the holders of such
     Designated Senior Indebtedness.

Notwithstanding the provisions described in the immediately preceding two
sentences (but subject to the provisions contained in the first sentence of this
Section 12.03), unless a Payment Default exists, any Guarantor shall be entitled
to resume payments pursuant to its Guaranty after termination of such Payment
Blockage Period. No Guarantor shall be subject to more than one Blockage Period
in any consecutive 360-day period, irrespective of the number of defaults with
respect to Designated Senior Indebtedness of such Guarantor during such period;
PROVIDED, HOWEVER, that if any Blockage Notice within such 360-day period is
given by or on behalf of any holders of Designated Senior Indebtedness of such
Guarantor (other than the Bank Indebtedness), the Representative of the Bank
Indebtedness shall be entitled to give another Blockage Notice within such
period; PROVIDED FURTHER, HOWEVER, that in no event shall the total number of
days during which any Payment Blockage Period or Periods is in effect exceed 179
days in the aggregate during any 360 consecutive day period.

          For purposes of this Section 12.03, no default or event of default
which existed or was continuing on the date of the commencement of any Payment
Blockage Period with respect to the Designated Senior Indebtedness of such
Guarantor initiating such Payment Blockage Period shall be, or be made, the
basis of the commencement of a subsequent Payment Blockage Period by the
Representative of such Designated Senior Indebtedness, whether or not within a
period of 360 consecutive days, unless such default or event of default shall
have been cured or waived for a period of not less than 90 consecutive days (it
being acknowledged that any subsequent action, or any breach of any financial
covenants for a period ending after the date of commencement of such Payment
Blockage Period that, in either case, would give rise to an event of default
pursuant to any provision under which an event of default previously existed or
was continuing shall constitute a new event of default for this purpose).

          SECTION 12.04 DEMAND FOR PAYMENT. If a demand for payment is made on a
Guarantor pursuant to Article 11, the Trustee shall promptly notify in writing
the holders of the Designated Senior Indebtedness of such Guarantor (or their
Representatives) of such demand (although the failure to give any such notice
shall not affect the subordinations of this Article 12). If any Designated
Senior Indebtedness of such Guarantor is outstanding, the Guarantor shall not
pay its Guaranty until five Business Days after the Representatives of all the
issues of Designated Senior Indebtedness of such Guarantor receive written
notice of such acceleration and,

<Page>

                                                                             105

thereafter, such Guarantor shall be entitled to pay its Guaranty (and the
Securityholders may accept and retain such payment) only if this Article 12
otherwise permits payment (and the acceptance and retention) at that time.

          SECTION 12.05 WHEN DISTRIBUTION MUST BE PAID OVER. If a distribution
or payment is made to (or received by) Securityholders that because of this
Article 12 should not have been made to (or received by) them, the Trustee or
Securityholders who receive the distribution or payment shall hold it in trust
for holders of Senior Indebtedness of the applicable Guarantor and pay it over
to them, as soon as practicable, as their interests may appear.

          SECTION 12.06 SUBROGATION. After all Senior Indebtedness of a
Guarantor is paid in full in cash and until the Securities are paid in full,
Securityholders shall be subrogated to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness of such
Guarantor. A distribution made under this Article 12 to holders of Senior
Indebtedness which otherwise would have been made to Securityholders is not, as
between the relevant Guarantor and Securityholders, a payment by such Guarantor
on such Senior Indebtedness.

          SECTION 12.07 RELATIVE RIGHTS. This Article 12 defines the relative
rights of Securityholders and holders of Senior Indebtedness of a Guarantor.
Nothing in this Indenture shall:

          (1)     impair, as between a Guarantor and Securityholders, the
     obligation of such Guarantor, which is absolute and unconditional, to pay
     its Guaranty to the extent set forth in Article 11; or

          (2)     prevent the Trustee or any Securityholder from exercising its
     available remedies upon a default by such Guarantor under its Guaranty,
     subject to the rights of holders of Senior Indebtedness of such Guarantor
     to receive distributions or payments otherwise payable to Securityholders.

          SECTION 12.08 SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY OR HOLDERS
OF SENIOR INDEBTEDNESS. No right of any holder of Senior Indebtedness of any
Guarantor to enforce the subordination of the Guaranty and other Obligations of
such Guarantor shall be impaired or prejudiced by any act or failure to act by
such Guarantor or any such holder or by such Guarantor's failure to comply with
this Indenture, in each case regardless of

<Page>

                                                                             106

any knowledge thereof which any such holder may have or otherwise be charged
with.

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Securityholders, without
incurring responsibility to the Trustee or the Securityholders and without
impairing or releasing the subordination provided in this Article 12 or the
obligations hereunder of the Trustee and the Securityholders to the holders of
Senior Indebtedness, do any one or more of the following: (1) change the manner,
place, terms or time of payment or extend the time of payment of, or renew or
alter, Senior Indebtedness or any instrument evidencing the same or any
agreement under which Senior Indebtedness is outstanding; (2) sell, exchange,
impair, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Indebtedness; (3) release any Person liable in any
manner for the collection or payment of Senior Indebtedness; and (4) exercise or
refrain from exercising any rights against such Guarantor or any other Person.

          SECTION 12.09 RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding
Section 12.03, the Trustee or Paying Agent shall continue to make payments on
any Guaranty and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than one
Business Day (or if notice is received after 1:00 p.m., New York City time, two
Business Days) prior to the date of such payment, a Trust Officer of the Trustee
receives written notice satisfactory to it that such payments are prohibited by
this Article 12. The Company, the relevant Guarantor, the Registrar or
co-registrar, the Paying Agent, a Representative or a holder of Senior
Indebtedness of such Guarantor shall be entitled to give the notice; PROVIDED,
HOWEVER, that, if an issue of Senior Indebtedness of any Guarantor has a
Representative, only the Representative shall be entitled to give the notice.
Nothing in this Section 12.09 is intended to or shall relieve any Securityholder
from the obligations imposed under Section 12.05 with respect to payments to
distributions received (whether from the Trustee or otherwise) in violation of
the provisions hereof.

          The Trustee in its individual or any other capacity shall be entitled
to hold Senior Indebtedness of any Guarantor with the same rights it would have
if it were not the Trustee. The Registrar and co-registrar and the Paying Agent
may do the same with like rights. The Trustee shall be entitled to all the
rights set forth in this Article 12 with respect to any Senior Indebtedness of
any Guarantor which may at any time be held by it,

<Page>

                                                                             107

to the same extent as any other holder of such Senior Indebtedness; and nothing
in Article 7 shall deprive the Trustee of any of its rights as such holder.
Nothing in this Article 12 shall apply to claims of, or payments to, the Trustee
(in its capacity as such) under or pursuant to Section 7.07.

          SECTION 12.10 DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever any
Person is to make a distribution or give a notice to holders of Senior
Indebtedness of any Guarantor, such Person shall be entitled to make such
distribution or give such notice to their Representative (if any).

          SECTION 12.11 ARTICLE 12 NOT TO PREVENT EVENTS OF DEFAULT OR LIMIT
RIGHT TO DEMAND PAYMENT. The failure to make a payment pursuant to a Guaranty by
reason of any provision in this Article 12 shall not be construed as preventing
the occurrence of a Default. Nothing in this Article 12 shall have any effect on
the right of the Securityholders or the Trustee to make a demand for payment on
any Guarantor pursuant to its Guaranty.

          SECTION 12.12 TRUSTEE ENTITLED TO RELY. Upon any payment or
distribution pursuant to this Article 12, the Trustee and the Securityholders
shall be entitled to rely

          (1)     upon any order or decree of a court of competent jurisdiction
     in which any proceedings of the nature referred to in Section 12.02 are
     pending,

          (2)     upon a certificate of the liquidating trustee or agent or
     other Person making such payment or distribution to the Trustee or to the
     Securityholders or

          (3)     upon the Representatives for the holders of Senior
     Indebtedness of any Guarantor

for the purpose of ascertaining the Persons entitled to participate in such
payment or distribution, the holders of such Senior Indebtedness and other
indebtedness of such Guarantor, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article 12.

          In the event that the Trustee determines, in good faith, that evidence
is required with respect to the right of any Person as a holder of Senior
Indebtedness of any Guarantor to participate in any payment or distribution
pursuant to this Article 12, the Trustee shall be entitled to request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the

<Page>

                                                                             108

amount of Senior Indebtedness of such Guarantor held by such Person, the extent
to which such Person is entitled to participate in such payment or distribution
and other facts pertinent to the rights of such Person under this Article 12,
and, if such evidence is not furnished, the Trustee shall be entitled to defer
any payment to such Person pending judicial determination as to the right of
such Person to receive such payment. The provisions of Sections 7.01 and 7.02
shall be applicable to all actions or omissions of actions by the Trustee
pursuant to this Article 12.

          SECTION 12.13 TRUSTEE TO EFFECTUATE SUBORDINATION. Each Securityholder
by accepting a Security authorizes and directs the Trustee on its behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate the
subordination between the Securityholders and the holders of Senior Indebtedness
of any Guarantor as provided in this Article 12 and appoints the Trustee as
attorney-in-fact for any and all such purposes.

          If neither the Trustee nor the Securityholders files a permitted claim
or proof of debt in the form required in any proceeding referred to in Section
6.01(7) or 6.01(8) prior to the tenth Business Day before the expiration of the
time to file such claim or claims, then any Representative of the holders of
Senior Indebtedness of the applicable Guarantor is hereby authorized to file
such appropriate claim for and on behalf of the Securityholders. Nothing herein
contained shall be deemed to authorize the Trustee or the holders of Senior
Indebtedness of any Guarantor or their Representative to authorize or consent to
or accept or adopt on behalf of any Securityholder any plan of reorganization,
arrangement, adjustment or composition affecting the Securities or the rights of
any Securityholder thereof, or to authorize the Trustee or the holders of Senior
Indebtedness of any Guarantor or their Representative to vote in respect of the
claim of any Securityholder in any such proceeding.

          SECTION 12.14 TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS
OF GUARANTOR. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness of any Guarantor and shall not be liable to any
such holders if it shall mistakenly pay over or distribute to Securityholders or
the Company or any other Person, money or assets to which any holders of such
Senior Indebtedness shall be entitled by virtue of this Article 12 or otherwise.

          SECTION 12.15 RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS OF GUARANTORS
ON SUBORDINATION PROVISIONS. Each Securityholder by accepting a Security
(whether upon original issue or upon transfer, assignment or exchange thereof)
acknowledges and agrees that the

<Page>

                                                                             109

foregoing subordination provisions are, and are intended to be, an inducement
and a consideration to each holder of any Senior Indebtedness of any Guarantor,
whether such Senior Indebtedness was created or acquired before or after the
issuance of the Securities, to acquire and continue to hold, or to continue to
hold, such Senior Indebtedness and such holder of Senior Indebtedness shall be
deemed conclusively to have relied on such subordination provisions in acquiring
and continuing to hold, or in continuing to hold, such Senior Indebtedness.

                                   ARTICLE 13

                                  MISCELLANEOUS

          SECTION 13.01 TRUST INDENTURE ACT CONTROLS. If any provision of this
Indenture limits, qualifies or conflicts with another provision which is
required to be included in this Indenture by the TIA, the required provision
shall control.

          SECTION 13.02 NOTICES. Any notice or communication shall be in writing
and delivered in person or mailed by first-class mail addressed as follows:

     if to the Company or any Guarantor:

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

          Any notice or communication mailed to a Securityholder shall be mailed
to the Securityholder at the Securityholder's address as it appears on the
registration books of the Registrar and shall be sufficiently given if so mailed
within the time prescribed.

          Failure to mail a notice or communication to a Securityholder or any
defect in it shall not affect its sufficiency with respect to other
Securityholders. If a notice or communication is mailed in the manner provided
above, it is duly given, whether or not the addressee receives it.

          SECTION 13.03 COMMUNICATION BY HOLDERS WITH OTHER HOLDERS.
Securityholders may communicate pursuant to TIA Section 312(b) with other
Securityholders with respect to their rights under this Indenture or the
Securities. The Company, each Guarantor, the Trustee, the Registrar and anyone
else shall have the protection of TIA Section 312(c).

          SECTION 13.04 CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT. Upon
any request or application by the Company to the Trustee to take or refrain from
taking any action under this Indenture, the Company shall furnish to the
Trustee:

          (1)     an Officers' Certificate in form and substance reasonably
     satisfactory to the Trustee stating that, in the opinion of the signers,
     all conditions precedent, if any, provided for in this Indenture relating
     to the proposed action have been complied with; and

          (2)     an Opinion of Counsel in form and substance reasonably
     satisfactory to the Trustee stating that, in the opinion of such counsel,
     all such conditions precedent have been complied with.

          SECTION 13.05 STATEMENTS REQUIRED IN CERTIFICATE OR OPINION. Each
certificate or opinion with respect to compliance with a covenant or condition

     opinion has read such covenant or condition;

                                                                             111

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

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

          (4)     a statement as to whether or not, in the opinion of such
     individual, such covenant or condition has been complied with.

          SECTION 13.06 WHEN SECURITIES DISREGARDED. In determining whether the
Holders of the required principal amount of Securities have concurred in any
direction, waiver or consent, Securities owned by the Company or by any Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company shall be disregarded and deemed not to be
outstanding, except that, for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Securities which the Trustee knows are so owned shall be so disregarded. Also,
subject to the foregoing, only Securities outstanding at the time shall be
considered in any such determination.

          SECTION 13.07 RULES BY TRUSTEE, PAYING AGENT AND REGISTRAR. The
Trustee may make reasonable rules for action by or a meeting of Securityholders.
The Registrar and the Paying Agent may make reasonable rules for their
functions.

          SECTION 13.08 LEGAL HOLIDAYS. A "Legal Holiday" is a Saturday, a
Sunday or a day on which banking institutions are not required to be open in the
State of New York. If a payment date is a Legal Holiday, payment shall be made
on the next succeeding day that is not a Legal Holiday, and no interest shall
accrue for the intervening period. If a regular record date is a Legal Holiday,
the record date shall not be affected.

          SECTION 13.09 GOVERNING LAW. This Indenture and the Securities shall
be governed by, and construed in accordance with, the laws of the State of New
York but without giving effect to applicable principles of conflicts of law to
the extent that the application of the laws of another jurisdiction would be
required thereby.

employee, incorporator or stockholder, as such, of the

Company under the Securities or this Indenture or any such Guarantor under any
Guaranty, as the case may be, or this Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation. By accepting a
Security, each Securityholder shall waive and release all such liability. The
waiver and release shall be part of the consideration for the issue of the
Securities.

          SECTION 13.11 SUCCESSORS. All agreements of the Company or any
Guarantor in this Indenture and the Securities shall bind its successors. All
agreements of the Trustee in this Indenture shall bind its successors.

          SECTION 13.12 MULTIPLE ORIGINALS. The parties may sign any number of
copies of this Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement. One signed copy is enough to prove this

without a legend containing restrictions on transfer of such Security prior to
the expiration of the Distribution Compliance Period and then only upon

transaction that did not require registration under the Securities Act. The Rule

Security and the Permanent Regulation S Global Security are collectively

<Page>

                                                                               7

existing between the Depository and the Securities Custodian, the aggregate
principal amount of Securities represented by the Rule 144A Global Security, IAI
Global Security or Permanent Regulation S Global Security, as applicable, to be

specified in such instructions a beneficial interest in the Rule 144A Global
Security, IAI Global Security or Permanent Regulation S Global Security, as
applicable, equal to the principal amount of the Definitive Security so

Regulation S Global Securities, as applicable, are then outstanding, the Company

Company in the form of an Officers' Certificate of the Company, a new Rule 144A

          (c)   TRANSFER AND EXCHANGE OF GLOBAL SECURITIES.

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

          (ii)  If the proposed transfer is a transfer of a beneficial interest
     in one Global Security to a beneficial interest in another Global Security,
     the Registrar shall reflect on its books and records the date and an
     increase in the principal amount of the Global Security to which such
     interest is being transferred in an amount equal to the principal amount of
     the interest to be so transferred, and the Registrar shall reflect on its
     books and records the date and a corresponding decrease in the principal

     than the provisions set forth in Section 2.4), a Global Security may not be
     transferred as a whole except by the Depository to a nominee of the
     Depository or by a nominee of the Depository to the Depository or another
     nominee of the Depository or by the Depository or any such nominee to a
     successor Depository or a nominee of such successor Depository.

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

SECURITIES. During the Distribution Compliance Period, beneficial ownership
interests in Temporary Regulation S Global Securities may only be sold, pledged
or transferred through Euroclear or Clearstream in accordance with the
Applicable Procedures and only (i) to the Company, (ii) so long as such Security
is eligible for resale pursuant to Rule 144A, to a Person whom the selling
holder reasonably believes is a QIB that purchases for its own account or for
the account of a QIB to whom notice is given that the resale, pledge or transfer
is being made in reliance on Rule 144A, (iii) to an IAI who is purchasing for
its own account or for the account of another institutional investor, in each
case in a minimum principal amount of the Securities of $250,000, for investment
purposes and not with a view to or for offer or sale in connection with any
distribution in violation of the Securities Act, (iv) in an offshore transaction

     or co-registrar's request.

          (ii)  No service charge shall be made for any registration of transfer
     or exchange, but the Company may require payment of a sum sufficient to
     cover any transfer tax, assessments, or similar governmental charge payable
     in connection therewith (other than any such transfer taxes, assessments or
     similar governmental charge payable upon exchange or transfer pursuant to
     Sections 3.06, 4.06, 4.09 and 9.05 of the Indenture).

     any co-registrar may deem and treat the person in whose name a Security is
     registered as the absolute owner of such Security for the purpose of
     receiving payment of principal of and interest on such Security and for all
     other purposes whatsoever, whether or not such Security is overdue, and

1.   INTEREST

          Rexnord Corporation, formerly known as RBS Holdings, Inc., a Delaware
corporation (such corporation, and its successors and assigns under the
Indenture hereinafter referred to, being herein called the "Company"), promises
to pay interest on the principal amount of this Security at the rate per annum
shown above. The Company will pay interest semiannually on June 15 and December
15 of each year, commencing June 15, 2003.

          Interest on the Securities will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from November 25,
2002. Interest on overdue principal will be paid by the Issuer at 1% per annum
in excess of the rate shown above and the Issuer will pay interest on overdue
installments of interest at such higher rate to the extent lawful. Interest on
the Securities also may increase in the event the Company fails to comply with
the requirements set forth in the Registration Rights Agreement. 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 Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the June 1 or December 1 next preceding the interest payment date
even if Securities are canceled after the record date and on or before the
interest payment date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money
of the United States that at the time of payment is legal tender for payment of
public and private debts. Payments in respect of the Securities represented by a

made by wire transfer of immediately available funds to the accounts specified
by The Depository Trust Company. The Company will make all payments in respect
of a certificated Security (including principal, premium, if any, and interest)
by mailing a check to the registered address of each Holder thereof; PROVIDED,
HOWEVER, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice

Agent to such effect designating such account no later than 30 days immediately
preceding the relevant due date for payment (or such other date as the Trustee
may accept in its discretion).

3.   PAYING AGENT AND REGISTRAR

          Initially, Wells Fargo Bank Minnesota, National Association (the
"Trustee"), will act as Paying Agent and Registrar. The Company may appoint and
change any Paying Agent, Registrar or co-registrar without notice. The Company
or any of its domestically incorporated Wholly Owned Subsidiaries may act as
Paying Agent, Registrar or co-registrar.

4.   INDENTURE

          The Company issued the Securities under an Indenture dated as of
November 25, 2002 (the "Indenture"), among the Company, the guarantors party
thereto and the Trustee. The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) as in effect on the date
of the Indenture (the "Act"). Terms defined in the Indenture and not defined
herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and
the Act for a statement of those terms.

          The Securities are general unsecured obligations of the Company. The
Securities issued on the Issue Date, any Additional Securities and any Exchange
Securities or Private Exchange Securities will be treated as a single class for
all purposes under the Indenture. The Indenture contains covenants that limit
the ability of the Company and its subsidiaries to incur additional
indebtedness; pay dividends or distributions on, or redeem or repurchase capital
stock; make investments; issue or sell capital stock of subsidiaries; engage in
transactions with affiliates; transfer or sell assets; guarantee indebtedness;
change their line of business; restrict dividends or other payments of
subsidiaries; and consolidate, merge or transfer all or substantially all of its
assets and the assets of its subsidiaries. These covenants are subject to
important exceptions and qualifications.

option to redeem all or a portion of the Securities upon not less than 30 nor
more than 60 days' notice, at the redemption prices (expressed in percentages of
principal amount on the redemption date), plus accrued interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date), if
redeemed during the 12-month period commencing on December 15 of the years set
forth below:

at its option on one or more occasions to redeem Securities (which includes
Additional Securities, if any) in an aggregate principal amount not to exceed
35% of the aggregate principal amount of the Securities originally issued at a
redemption price (expressed as a percentage of principal amount) of 110.125%,
plus accrued and unpaid interest to the redemption date, with the net cash
proceeds received by the Company from one or more Equity Offerings (PROVIDED
that, if the Equity Offering is an offering by Parent, a portion of the Net Cash
Proceeds thereof equal to the amount required to redeem any such Notes is
contributed to the equity capital of the Company or used to acquire Capital
Stock of the Company (other than Disqualified Stock) from the Company);
PROVIDED, HOWEVER, that (1) at least 65% of such aggregate principal amount of
Securities (which includes Additional Securities, if any) remains outstanding
immediately after the occurrence of each such redemption (other than Securities
held, directly or indirectly, by the Company or its Affiliates); and (2) each
such redemption occurs within 90 days after the date of the related Equity
Offering.

6.   NOTICE OF REDEMPTION

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each Holder of Securities to be redeemed
at its registered address. Securities in denominations larger than $1,000
principal amount may be redeemed in part but only in whole multiples of $1,000.
Securities in denominations of $1,000 principal amount or less may be redeemed
in whole but not in part. If money sufficient to pay the redemption price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

7.   PUT PROVISIONS

          Upon a Change of Control, any Holder of Securities will have the right
to cause the Company to repurchase all of the Securities of such Holder at a
repurchase price equal to 101% of the principal amount of the Securities to be
repurchased plus accrued interest to the date of repurchase (subject to the
right of holders of record on the relevant record date to receive interest due
on the related interest payment date) as provided in, and subject to the terms
of, the Indenture.

8.   SUBORDINATION

          The Securities are subordinated to Senior Indebtedness of the Company,
as defined in the Indenture. To the extent provided in the Indenture, Senior
Indebtedness of the Company must be paid before the Securities may be paid. The
Company agrees, and each Securityholder by accepting a Security agrees, to the
subordination provisions contained in the Indenture and authorizes the Trustee
to give it effect and appoints the Trustee as attorney-in-fact for such purpose.

9.   GUARANTY

          The payment by the Company of the principal of, and premium and
interest on, the Securities is fully and unconditionally guaranteed on a joint
and several senior subordinated basis by each of the Guarantors.

                                                                              12

10.  DENOMINATIONS; TRANSFER; EXCHANGE

          The Securities are in registered form without coupons in denominations
of $1,000 principal amount and whole multiples of $1,000. A Holder may transfer
or exchange Securities in accordance with the Indenture. The Registrar may
require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not register the transfer or exchange of any
Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or any
Securities for a period of 15 days before a selection of Securities to be
redeemed or 15 days before an interest payment date.

11.  PERSONS DEEMED OWNERS

          The registered Holder of this Security may be treated as the owner of
it for all purposes.

12.  UNCLAIMED MONEY

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

13.  DISCHARGE AND DEFEASANCE

          Subject to certain conditions, the Company at any time shall be
entitled to terminate some or all of its obligations under the Securities and
the Indenture, and the obligations of the Guarantors under their Guaranties, if
the Company deposits with the Trustee money or U.S. Government Obligations for
the payment of principal and interest on the Securities to redemption or
maturity, as the case may be.

14.  AMENDMENT; WAIVER

          Subject to certain exceptions set forth in the Indenture, (i) the
Indenture and the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Securities
and (ii) any default or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in principal

<Page>

                                                                              13

amount outstanding of the Securities. Subject to certain exceptions set forth in
the Indenture, without the consent of any Securityholder, the Company, the
Guarantors and the Trustee shall be entitled to amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article 5 of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities, or to add
guarantees with respect to the Securities, including Subsidiary Guaranties, or
to secure the Securities, or to add additional covenants or surrender rights and
powers conferred on the Company or the Guarantors, or to comply with any request
of the SEC in connection with qualifying the Indenture under the Act, or to make
certain changes in the subordination provisions, or to make any change that does
not adversely affect the rights of any Securityholder.

15.  DEFAULTS AND REMEDIES

          Under the Indenture, Events of Default include (i) default for 30 days
in payment of interest on the Securities; (ii) default in payment of principal
on the Securities at maturity, upon redemption pursuant to paragraph 5 of the
Securities, upon acceleration or otherwise, or failure by the Company to redeem
or purchase Securities when required; (iii) failure by the Company or any
Guarantor to comply with other agreements in the Indenture or the Securities, in
certain cases subject to notice and lapse of time; (iv) certain accelerations
(including failure to pay within any grace period after final maturity) of other
Indebtedness of the Company, Parent or any Significant Subsidiary if the amount
accelerated (or so unpaid) exceeds $20.0 million; (v) certain events of
bankruptcy or insolvency with respect to the Company, Parent and the Significant
Subsidiaries; (vi) certain judgments or decrees for the payment of money in
excess of $20.0 million; and (vii) certain defaults with respect to the
Guaranties. If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all
the Securities to be due and payable immediately. Certain events of bankruptcy
or insolvency are Events of Default which will result in the Securities being
due and payable immediately upon the occurrence of such Events of Default.

          Securityholders may not enforce the Indenture or the Securities except
as provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives indemnity or security satisfactory to it.
Subject to certain limitations, Holders of a majority in principal amount

<Page>

                                                                              14

of the Securities may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Securityholders notice of any continuing Default
(except a Default in payment of principal or interest) if it determines that
withholding notice is not opposed to the interest of the Holders.

16.  TRUSTEE DEALINGS WITH THE COMPANY

          Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

17.  NO RECOURSE AGAINST OTHERS

          A director, officer, employee or stockholder, as such, of the Company
or the Trustee shall not have any liability for any obligations of the Company
under the Securities or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation. By accepting a Security,
each Securityholder waives and releases all such liability. The waiver and
release are part of the consideration for the issue of the Securities.

18.  AUTHENTICATION

          This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

19.  ABBREVIATIONS

          Customary abbreviations may be used in the name of a Securityholder or
an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

20.  CUSIP NUMBERS

Security Identification Procedures the Company has caused CUSIP numbers to be

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

21.  HOLDERS' COMPLIANCE WITH REGISTRATION RIGHTS AGREEMENT.

          Each Holder of a Security, by acceptance hereof, acknowledges and
agrees to the provisions of the Registration Rights Agreement, including the
obligations of the Holders with respect to a registration and the
indemnification of the Company to the extent provided therein.

          THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
