                          DEFINITIONS AND INCORPORATION
                                  BY REFERENCE

Section 1.01.     Definitions.

         "Acquired Debt" means, with respect to any specified Person:

         (1)      Indebtedness of any other Person existing at the time such
                  other Person is merged with or into or became a Restricted
                  Subsidiary of such specified Person, whether or not such
                  Indebtedness is incurred in connection with, or in
                  contemplation of, such other Person merging with or into, or
                  becoming a Restricted Subsidiary of, such specified Person;
                  and

         (2)      Indebtedness secured by a Lien encumbering any asset acquired
                  by such specified Person.

         "Affiliate" of any specified Person means any other Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such specified Person. For purposes of this definition, "control,"
as used with respect to any Person, means the possession, directly or
indirectly, of the power to direct or cause the direction of the management or
policies of such Person, whether through the ownership of voting securities, by
agreement or otherwise; provided that Beneficial Ownership of 10% or more of the
Voting Stock of a Person will be deemed to be control. For purposes of this
definition, the terms "controlling," "controlled by" and "under common control
with" have correlative meanings.

         "Agent" means any Registrar or Paying Agent.

         "Agent Members" means members of, or Participants in, the Depository.

         "Applicable Procedures" means the applicable procedures of the
Depository.

         "Asset Sale" means:

         (1)      the sale, lease, conveyance or other disposition of any assets
                  or rights, other than sales of inventory in the ordinary
                  course of business consistent with past practices; provided
                  that the sale, conveyance or other disposition of all or
                  substantially all of the assets of the Company and its
                  Restricted Subsidiaries taken

                                       1

                  as a whole will be governed by Section 4.15 and Section 5.01
                  and not by Section 4.10; and

         (2)      the issuance of Equity Interests by any of the Company's
                  Restricted Subsidiaries or the sale of Equity Interests in any
                  of its Restricted Subsidiaries.

                  Notwithstanding the preceding, the following items will not be
deemed to be Asset Sales:

         (1)      any single transaction or series of related transactions that
                  involves assets having a fair market value of less than $5.0
                  million;

         (2)      a transfer of assets between or among the Company and its
                  Restricted Subsidiaries,

         (3)      an issuance of Equity Interests by a Restricted Subsidiary to
                  the Company or to another Restricted Subsidiary;

         (4)      the sale or lease of equipment, inventory, accounts receivable
                  or other assets in the ordinary course of business;

         (5)      the sale or other disposition of cash or Cash Equivalents; and

         (6)      a Restricted Payment or Permitted Investment that is permitted
                  by Section 4.07.

         "Attributable Debt" at any date, means the present value of all
remaining rental payments under leases with an initial term of more than one
year under which the Company or any of its Restricted Subsidiaries is liable as
a lessee, including any rental payments during any period for which the lease
may be extended at the election of the lessor, discounted on a semi-annual basis
at a per annum discount rate equal to the greater of:

         (1)      the weighted average Yield to Maturity of the Notes; and

         (2)      the interest rate inherent in such lease.

         "Bankruptcy Law" means Title 11, U.S. Code or any similar federal or
state law for the relief of debtors.

         "Beneficial Owner" has the meaning assigned to such term in Rule 13d-3
and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial
ownership of any particular "person" (as that term is used in Section 13(d)(3)
of the Exchange Act), such "person" will be deemed to have beneficial ownership
of all securities that such "person" has the right to acquire by conversion or
exercise of other securities, whether such right is currently exercisable or is
exercisable only upon the occurrence of a subsequent condition. The terms
"Beneficially Owns" and "Beneficially Owned" have a corresponding meaning.

Section 2.01.     Form and Dating.

         (a) General. The Notes and the Trustee's certificate of authentication
shall be substantially in the form of Exhibit A attached hereto. The Notes may
have notations, legends or endorsements required by law, stock exchange rule or
usage. Each Note shall be dated the date of its authentication. The Notes shall
be in denominations of $1,000 and integral multiples thereof.

         The terms and provisions contained in the Notes shall constitute, and
are hereby expressly made, a part of this Indenture and the Company, the
Guarantors and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby. However,

thereby may from time to time be reduced or increased, as appropriate, to

amount of outstanding Notes represented thereby shall be made by the Trustee or

or to a successor of the Depository or its nominee.

         (c)      Book-Entry Provisions.

         The Company shall execute and the Trustee shall, in accordance with
this Section 2.01(c), authenticate and deliver the Global Notes that (i) shall
be registered in the name of the Depository or the nominee of the Depository and
(ii) shall be delivered by the Trustee to the Depository or pursuant to the
Depository's instructions or held by the Trustee as custodian for the
Depository.

         Agent Members shall have no rights either under this Indenture with
respect to any Global Note held on their behalf by the Depository or by the
Trustee as custodian for the Depository or under such Global Note, and the
Depository may be treated by the Company, the Trustee and any Agent as the
absolute owner of such Global Note for all purposes whatsoever. Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Trustee or any
Agent from giving effect to any written certification, proxy or other
authorization furnished by the Depository or impair, as between the Depository
and its Agent Members, the operation of customary practices of such Depository
governing the exercise of the rights of an owner of a beneficial interest in any
Global Note.

         (d) Definitive Notes. Notes issued in certificated form shall be
substantially in the form of Exhibit A attached hereto (but without including
the Global Note Legend or the Schedule of Exchanges of Interests in the Global
Note).

Section 2.02.     Execution and Authentication.

         Two Officers shall sign the Notes for the Company by manual or
facsimile signature.

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

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

         The Trustee shall, upon a written order of the Company signed by two
Officers (an "Authentication Order"), authenticate Senior Notes for original
issue up to the aggregate principal amount of $275,000,000. The Trustee shall,
upon an Authentication Order, authenticate Exchange Notes for original issue up
to the aggregate principal amount of Senior Notes exchanged in the Exchange
Offer or otherwise exchanged for Senior Notes pursuant to the Registration
Rights Agreement. The aggregate principal amount of Notes outstanding at any
time may not exceed $275,000,000 except as provided in Section 2.07.

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

Section 2.03.     Registrar and Paying Agent.

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

act as Depository with respect to the Global Notes.

Paying Agent and to act as custodian with respect to the Global Notes.

Section 2.04.     Paying Agent to Hold Money in Trust.

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

Section 2.05.     Holder Lists.

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

<PAGE>   30

Depository to the Depository or to another nominee of the Depository, or by the
Depository or any such nominee to a successor Depository or a nominee of such
successor Depository. All Global Notes will be exchanged by the Company for
Definitive Notes if (i) the Company delivers to the Trustee notice from the
Depository that it is unwilling or unable to continue to act as Depository or
that it is no longer a clearing agency registered under the Exchange Act and, in
either case, a successor Depository is not appointed by the Company within 120
days after the date of such notice from the Depository, (ii) the Company in its
sole discretion determines that the Global Notes (in whole but not in part)
should be exchanged for Definitive Notes and delivers a written notice to such
effect to the Trustee or (iii) there has occurred and is continuing for a period
of 120 days a Default or Event of Default with respect to the Notes. Upon the
occurrence of either of the preceding events in (i) or (ii) above, Definitive
Notes shall be issued in such names as the Depository shall instruct the
Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as
provided in Sections 2.07 and 2.10. Every Note authenticated and delivered in
exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to
this Section 2.06, Section 2.07 or Section or 2.10, shall be authenticated and
delivered in the form of, and shall be, a Global Note. A Global Note may not be
exchanged for another Note other than as provided in this Section 2.06(a),
however, beneficial interests in a Global Note may be transferred and exchanged
as provided in Section 2.06(b), (c) or (f).

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

                  (i) Transfer of Beneficial Interests in the Same Global Note.
         Beneficial interests in any Restricted Global Note may be transferred
         to Persons who take delivery thereof in the form of a beneficial
         interest in the same Restricted Global Note in accordance with the
         transfer restrictions set forth in the Private Placement Legend.
         Beneficial interests in any Unrestricted Global Note may be transferred
         to Persons who take delivery thereof in the form of a beneficial
         interest in an Unrestricted Global Note. No written orders or
         instructions shall be required to be delivered to the Registrar to
         effect the transfers described in this Section 2.06(b)(i).

                  (ii) All Other Transfers and Exchanges of Beneficial Interests
         in Global Notes. In connection with all transfers and exchanges of
         beneficial interests that are not subject to Section 2.06(b)(i), the
         transferor of such beneficial interest must deliver to the Registrar
         either (A)(1) a written order from a Participant or an Indirect
         Participant given to the Depository in accordance with the Applicable
         Procedures directing the Depository to credit or cause to be credited a
         beneficial interest in another Global Note in an amount equal to the
         beneficial interest to be transferred or exchanged and (2) instructions
         given in accordance with the Applicable Procedures containing

                  the Registrar so requests or if the Applicable Procedures so
                  require, an Opinion of Counsel in form reasonably acceptable
                  to the Registrar to the effect that such exchange or transfer
                  is in compliance with the Securities Act and that the
                  restrictions on transfer contained herein and in the Private
                  Placement Legend are no longer required in order to maintain
                  compliance with the Securities Act.

         Upon satisfaction of the conditions of any of the subparagraphs in this
Section 2.06(d)(ii), the Trustee shall cancel the Definitive Notes and increase
or cause to be increased the aggregate principal amount of the Unrestricted
Global Note.

                  (iii) Unrestricted Definitive Notes to Beneficial Interests in
         Unrestricted Global Notes. A Holder of an Unrestricted Definitive Note
         may exchange such Note for a beneficial interest in an Unrestricted
         Global Note or transfer such Definitive Notes to a Person who takes
         delivery thereof in the form of a beneficial interest in an
         Unrestricted Global Note at any time. Upon receipt of a request for
         such an exchange or transfer, the Trustee shall cancel the applicable
         Unrestricted Definitive Note and increase or cause to be increased the
         aggregate principal amount of one of the Unrestricted Global Notes.

                  If any such exchange or transfer from a Definitive Note to a
         beneficial interest is effected pursuant to subparagraphs (ii)(B),
         (ii)(D) or (iii) above at a time when an Unrestricted Global Note has
         not yet been issued, the Company shall issue and, upon receipt of an
         Authentication Order in accordance with Section 2.02, the Trustee shall
         authenticate one or more Unrestricted Global Notes in an aggregate
         principal amount equal to the principal amount of Definitive Notes so
         transferred.

         (e) Transfer and Exchange of Definitive Notes for Definitive Notes.
Upon request by a Holder of Definitive Notes and such Holder's compliance with
the provisions of this Section

                                       31

2.06(e), the Registrar shall register the transfer or exchange of Definitive
Notes. Prior to such registration of transfer or exchange, the requesting Holder

         of a Restricted Definitive Note if the Registrar receives the
         following:

                           (A) if the transfer will be made pursuant to Rule
                  144A, then the transferor must deliver a certificate in the
                  form of Exhibit B attached hereto, including the
                  certifications in item (1) thereof;

                           (B) if the transfer will be made pursuant to any
                  other exemption from the registration requirements of the
                  Securities Act, then the transferor must deliver a certificate
                  in the form of Exhibit B attached hereto, including the
                  certifications, certificates and Opinion of Counsel required

                  (ii) Restricted Definitive Notes to Unrestricted Definitive
         Notes. Any Restricted Definitive Note may be exchanged by the Holder
         thereof for an Unrestricted Definitive Note or transferred to a Person
         or Persons who take delivery thereof in the form of an Unrestricted
         Definitive Note if:

                           (A) such exchange or transfer is effected pursuant to
                  the Exchange Offer in accordance with the Registration Rights
                  Agreement and the Holder, in the case of an exchange, or the
                  transferee, in the case of a transfer, certifies in the
                  applicable Letter of Transmittal that it is not (1) a
                  Broker-Dealer, (2) a Person participating in the distribution
                  of the Exchange Notes or (3) a Person who is an affiliate (as
                  defined in Rule 144) of the Company;

                           (B) any such transfer is effected pursuant to the
                  Shelf Registration Statement in accordance with the
                  Registration Rights Agreement;

                           (C) any such transfer is effected by a Broker-Dealer
                  pursuant to the Exchange Offer Registration Statement in
                  accordance with the Registration Rights Agreement; or

                           (D) the Registrar receives the following:

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

                                       32

<PAGE>   38

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

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

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

         (f) Exchange Offer. Upon the occurrence of the Exchange Offer in
accordance with the Registration Rights Agreement, the Company shall issue and,
upon receipt of an Authentication Order in accordance with Section 2.02, the
Trustee shall authenticate (i) one or more Unrestricted Global Notes in an
aggregate principal amount equal to the principal amount of the beneficial
interests in the Restricted Global Notes tendered for acceptance by Persons that
certify in the applicable Letters of Transmittal that (x) they are not
Broker-Dealers, (y) they are not participating in a distribution of the Exchange
Notes and (z) they are not affiliates (as defined in Rule 144) of the Company,
and accepted for exchange in the Exchange Offer and (ii) Definitive Notes in an
aggregate principal amount equal to the principal amount of the Restricted
Definitive Notes accepted for exchange in the Exchange Offer. Concurrently with
the issuance of such Notes, the Trustee shall cause the aggregate principal
amount of the applicable Restricted Global Notes to be reduced accordingly, and
the Company shall execute and the Trustee shall authenticate and deliver to the
Persons designated by the Holders of Definitive Notes so accepted Definitive
Notes in the appropriate principal amount.

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

                  issued in exchange therefor or substitution thereof) shall
                  bear the legend in substantially the following form:

"THE NOTES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES
SECURITIES ACT OF 1933 (THE "SECURITIES ACT") AND MAY NOT BE OFFERED, SOLD,

OF THE STATES OF THE UNITED STATES."

                           (B) Notwithstanding the foregoing, any Global Note or
                  Definitive Note issued pursuant to subparagraphs (b)(iv),
                  (c)(ii), (c)(iii), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f)

                  therefor or substitution thereof) shall not bear the Private
                  Placement Legend.

                  (ii) Global Note Legend. Each Global Note shall bear a legend
         in substantially the following form:

"THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE
GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL

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

Global Note by the Trustee or by the Depository at the direction of the Trustee
to reflect such increase.

         (i) General Provisions Relating to Transfers and Exchanges.

                  (i) To permit registrations of transfers and exchanges, the
         Company shall execute and the Trustee shall authenticate Global Notes
         and Definitive Notes upon the Company's order or at the Registrar's
         request.

                  (ii) No service charge shall be made to a holder of a
         beneficial interest in a Global Note or to a Holder of a Definitive
         Note for any registration of transfer or exchange, but the Company may
         require payment of a sum sufficient to cover any transfer tax or
         similar governmental charge payable in connection therewith (other than
         any such transfer taxes or similar governmental charge payable upon
         exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15
         and 9.05).

                  (iii) The Registrar shall not be required to register the
         transfer of or exchange any Note selected for redemption in whole or in
         part, except the unredeemed portion of any Note being redeemed in part.

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

                  (v) The Company shall not be required (A) to issue, to
         register the transfer of or to exchange any Notes during a period
         beginning at the opening of business 15 days before the day of any
         selection of Notes for redemption under Section 3.02 and ending at the
         close of business on the day of selection, (B) to register the transfer
         of or to exchange any Note so selected for redemption in whole or in
         part, except the unredeemed portion of any Note being redeemed in part
         or (C) to register the transfer of or to exchange a Note between a
         record date and the next succeeding Interest Payment Date.

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

                  (vii) The Trustee shall authenticate Global Notes and
         Definitive Notes in accordance with the provisions of Section 2.02.

Section 2.07. Replacement Notes.

         If any mutilated Note is surrendered to the Trustee or the Company and
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Note, the Company shall issue and the Trustee, upon receipt of an
Authentication Order, shall authenticate a replacement Note if the Trustee's
requirements are met. If required by the Trustee or the Company, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Company may charge for its expenses in replacing a Note.

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

Section 2.08. Outstanding Notes.

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

         If a Note is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser. A mutilated Note ceases to be
outstanding upon surrender of such Note and replacement thereof pursuant to
Section 2.07.

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

         If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a Redemption Date, any date of repurchase
pursuant to Section 4.15 or maturity date, money sufficient to pay Notes payable
on that date, then on and after that date such Notes shall be deemed to be no
longer outstanding and shall cease to accrue interest.

Section 2.09. Treasury Notes.

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Affiliate of the Company, shall be considered as though not
outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Notes that the Trustee knows are so owned shall be so disregarded.

Section 2.10. Temporary Notes.

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

                                       36
<PAGE>   42

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

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

Section 2.11. Cancellation.

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

Section 2.12. Defaulted Interest.

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

                            REDEMPTION AND PREPAYMENT

Section 3.01. Notices to Trustee.

         If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07, it shall furnish to the Trustee, at least
15 days (unless a shorter notice period shall be satisfactory to the Trustee)
but not more than 60 days before a Redemption Date, an Officer's Certificate
setting forth (i) the Redemption Date, (ii) the principal amount of Notes to be
redeemed and (iii) the redemption price.

Section 3.02. Selection of Notes to Be Redeemed.

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

                                       37
<PAGE>   43

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

         (b) if the Notes are not listed on any national securities exchange, on
a pro rata basis by lot or such method as the Trustee shall deem fair and
appropriate. In the event of partial redemption by lot, the particular Notes to
be redeemed shall be selected, unless otherwise provided herein, not less than
30 nor more than 60 days prior to the Redemption Date by the Trustee from the
outstanding Notes not previously called for redemption.

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

         No Notes of $1,000 or less, if any, can be redeemed in part.

Section 3.03. Notice of Redemption.

         Notices of redemption shall be given in accordance with Section 14.02
at least 30 but not more than 60 days before the Redemption Date, except that
redemption notices may be given more than 60 days prior to a Redemption Date if
the notice is issued in connection with a defeasance of the Notes or a
satisfaction and discharge of this Indenture.

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

         (a) the Redemption Date;

         (b) the redemption price and the amount of accrued interest and Special
Interest, if any, to the Redemption Date;

         (c) if less than all outstanding Notes are to be redeemed, the
aggregate principal amount of Notes which will be outstanding after such partial
redemption;

         (d) if any Note is to be redeemed in part only, the portion of the
principal amount of that Note that is to be redeemed, and that, after the
Redemption Date, upon surrender of that Note, a new Note in principal amount
equal to the unredeemed portion of that Note will be issued;

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

         (f) that Notes called for redemption must be surrendered to the Paying
Agent to collect the redemption price, the amount of accrued interest and
Special Interest, if any;

                                       38
<PAGE>   44

         (g) that, unless the Company defaults in making such redemption
payment, interest, and Special Interest, if any, on Notes called for redemption
ceases to accrue on and after the Redemption Date;

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

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

         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 45 days prior to the
Redemption Date, an Officer's Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

Section 3.04. Effect of Notice of Redemption.

         Notes called for redemption become due on the Redemption Date. Subject
to Section 3.05, on and after the Redemption Date, interest and Special
Interest, if any, cease to accrue on Notes or portions of them called for
redemption. Notices of redemption may not be conditional.

Section 3.05. Deposit of Redemption Price.

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

         If the Company complies with the provisions of the preceding paragraph,
on and after the Redemption Date, interest and Special Interest, if any, shall
cease to accrue on the Notes or the portions of Notes called for redemption. If
a Note is redeemed on or after an interest record date but on or prior to the
related Interest Payment Date, then any accrued and unpaid interest shall be
paid to the Person in whose name such Note was registered at the close of
business on such record date. If any Note called for redemption shall not be so
paid upon surrender for redemption because of the failure of the Company to
comply with the preceding paragraph, interest shall be paid on the unpaid
principal, from the Redemption Date until such principal is paid, and to the
extent lawful on any interest not paid on such unpaid principal, in each case at
the rate provided in the Notes and in Section 4.01.

Section 3.06. Notes Redeemed in Part.

         If any Note is to be redeemed in part only, the notice of redemption
that relates to that Note will state the portion of the principal amount of that
Note that is to be redeemed. A new

                                       39
<PAGE>   45

Note in principal amount equal to the unredeemed portion of the original Note
will be issued in the name of the Holder of that Note upon cancellation of the
Note redeemed in part.

Section 3.07. Optional Redemption.

         The Notes may be redeemed in whole at any time or in part from time to
time, at the option of the Company, at a redemption price equal to the greater
of:

         (1)      100% of the principal amount of the Notes to be redeemed, and

         (2)      the sum of the present values of the remaining scheduled
                  payments of principal and interest on the Notes to be redeemed
                  (exclusive of interest accrued to the Redemption Date)
                  discounted to the Redemption Date on a semi-annual basis
                  (assuming a 360-year consisting of twelve 30-day months) at
                  the applicable Treasury Rate plus 50 basis points, plus
                  accrued and unpaid interest on the principal amount being
                  redeemed to the Redemption Date.

         Except pursuant to the preceding paragraph, the Notes will not be
redeemable at the Company's option prior to maturity.

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

Section 3.08. Mandatory Redemption.

         Except as set forth under Sections 4.10 and 4.15, the Company is not
required to make mandatory redemption or sinking fund payments with respect to
the Notes.

Section 3.09. Offer to Purchase by Application of Excess Proceeds.

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

         The Asset Sale Offer shall remain open for a period of 20 Business Days
following its commencement and no longer, except to the extent that a longer
period is required by applicable law (the "Offer Period"). No later than five
Business Days after the termination of the Offer Period (the "Purchase Date"),
the Company shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.10 (the "Offer Amount") or, if less than the
Offer Amount has been tendered all Notes tendered in response to the Asset Sale
Offer. Payment for any Notes so purchased shall be made in the same manner as
interest payments are made.

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

                                       40
<PAGE>   46

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

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

         (b) the Offer Amount, the purchase price, the amount of accrued and
unpaid interest and Special Interest, if any, as of the Purchase Date and the
Purchase Date;

         (c) that any Note not tendered or accepted for payment shall continue
to accrete or accrue interest and Special Interest, if any;

         (d) that, unless the Company defaults in making such payment, any Note
accepted for payment pursuant to the Asset Sale Offer shall cease to accrete or
accrue interest and Special Interest, if any, after the Purchase Date;

         (e) that Holders electing to have a Note purchased pursuant to an Asset
Sale Offer may only elect to have all of such Notes purchased and may not elect
to have only a portion of such Note purchased;

         (f) that Holders electing to have a Note purchased pursuant to any
Asset Sale Offer shall be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Note completed, or
transfer by book-entry transfer, to the Company, a depositary, if appointed by
the Company, or a Paying Agent at the address specified in the notice at least
three days before the Purchase Date;

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

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

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

         On the Purchase Date for any Asset Sale Offer, the Company shall (i)
accept for payment the maximum principal amount of Notes tendered pursuant to
such Asset Sale Offer than can be purchased out of Excess Proceeds from such
Asset Sales, (ii) deposit with the Paying Agent the aggregate purchase price of
all Notes accepted for payment and any accrued and unpaid interest

                                       41
<PAGE>   47

and Special Interest, if any, on such Notes as of the Purchase Date, and (iii)
deliver or cause to be delivered to the Trustee all Notes tendered pursuant to
the Asset Sale Offer. If less than all Notes tendered pursuant to any Asset Sale
Offer are accepted for payment by the Company for any reason, selection of the
Notes to be purchased by the Trustee shall be in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed or, if the Notes are not so listed, by lot or by such method as
the Trustee shall deem fair and appropriate; provided that Notes accepted for
payment in part shall only be purchased in integral multiples of $1,000. The
Paying Agent shall promptly mail to each Holder of Notes accepted for payment an
amount equal to the purchase price for such Notes plus any accrued and unpaid
interest and Special Interest thereon, if any, and the Trustee shall promptly
authenticate and mail to such Holder of Notes accepted for payment in part a new
Note equal in principal amount to any unpurchased portion of the Notes, and any
Note not accepted for payment in whole or in part shall be promptly returned to
the Holder of such Note. On and after a Purchase Date, interest and Special
Interest, if any, shall cease to accrue on the Notes accepted for payment. The
Company shall announce the results of the Offer to Holders of the Notes on or as
soon as practicable after the Purchase Date.

         Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06.

Eastern Time on the due date money deposited by the Company in immediately
available funds and designated for and sufficient to pay all principal, premium,

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

                  quarter for which internal financial statements are available
                  at the time of such Restricted Payment (or, if such

                  100% of such deficit), plus

                           (B) 100% of the aggregate net cash proceeds received
                  by the Company since the date of this Indenture as a

                  exchangeable debt securities of the Company that have been
                  converted into or exchanged for such Equity Interests (other

                  securities) sold to a Restricted Subsidiary of the Company),
                  plus

                           (C) the amount by which Indebtedness of the Company
                  or its Restricted Subsidiaries (other than Indebtedness owed

                  (less the amount of any cash, or the fair value of any other
                  property, distributed by the Company upon such conversion or

                  reduction in Investments in Unrestricted Subsidiaries
                  resulting from dividends, repayments of loans or advances or
                  other transfers of assets, in each case to the Company or any
                  of its Restricted Subsidiaries from any of its Unrestricted
                  Subsidiaries, and (ii) the portion (proportionate to the
                  Company's equity interest in such Subsidiary) of the fair
                  market value of the net assets of an Unrestricted Subsidiary
                  at the time such Unrestricted Subsidiary is designated a
                  Restricted Subsidiary; provided, however, that the foregoing
                  sum shall not exceed, in the case of any Unrestricted
                  Subsidiary, the amount of Investments previously made (and
                  treated as a Restricted Payment) by the Company or any of its
                  Restricted Subsidiaries in such Unrestricted Subsidiary, plus

                           (E) to the extent that any Restricted Investment that
                  was made after the date of this Indenture is sold for cash or
                  otherwise liquidated or repaid for cash, the lesser of (i) the

thereby, the preceding paragraph of this Section 4.07 shall not prohibit:

         (a) the payment of any dividend within 60 days after the date of
declaration of the dividend, if at the date of declaration the dividend payment

value of any Equity Interests of the Company or any Restricted Subsidiary of the
Company held by any member of the Company's (or any of its Restricted
Subsidiaries') management pursuant to any management equity subscription
agreement, stock option agreement, employee benefit plan or similar agreement;
provided that the aggregate price paid for all such repurchased, redeemed,
acquired or retired Equity Interests may not exceed $1.0 million in any
twelve-month period; and

         (f) other Restricted Payments in the aggregate not to exceed $50.0
million since the date of this Indenture.

         The amount of all Restricted Payments (other than cash) shall be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any assets or securities that are required to be valued
by this covenant shall be determined by the Board of Directors whose resolution
with respect thereto shall be delivered to the Trustee. Not later than the date
of making any Restricted Payment, the Company will deliver to the Trustee an
Officer's Certificate stating that such Restricted Payment is permitted and
setting forth the basis upon which the calculations required by this covenant
were computed.

Section 4.08. Dividend and Other Payment Restrictions Affecting Restricted
              Subsidiaries.

         Until such time as the Company meets the Rating Condition, the Company
shall not, and shall not permit any of its Restricted Subsidiaries to, directly
or indirectly, create or permit to exist or become effective any consensual
encumbrance or restriction on the ability of any Restricted Subsidiary to:

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

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

                                       47
<PAGE>   53

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

         However, the preceding restrictions shall not apply to encumbrances or
restrictions existing under or by reason of:

         (a) agreements governing Existing Indebtedness and Credit Facilities as
in effect on the date of this Indenture and any amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or
refinancings of those agreements, provided that the amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacement or
refinancings are no more restrictive, taken as a whole, with respect to such
dividend and other payment restrictions than those contained in those agreements
on the date of this Indenture;

         (b) this Indenture, the Notes, the Subsidiary Guarantees and the
Convertible Senior Notes;

         (c) applicable law;

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

         (e) customary non-assignment provisions in leases entered into in the
ordinary course of business and consistent with past practices;

         (f) purchase money obligations for property acquired in the ordinary
course of business that impose restrictions on that property of the nature
described in clause (c) of the preceding paragraph;

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

         (h) Permitted Refinancing Indebtedness, provided that the restrictions
contained in the agreements governing such Permitted Refinancing Indebtedness
are no more restrictive, taken as a whole, than those contained in the
agreements governing the Indebtedness being refinanced;

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

                                       48
<PAGE>   54

         (j) provisions with respect to the disposition or distribution of
assets or property in joint venture agreements, assets sale agreements, stock
sale agreements and other similar agreements entered into in the ordinary course
of business; or

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

Section 4.09. Incurrence of Indebtedness and Issuance of Preferred Stock.

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

         The first paragraph of this covenant shall not prohibit the incurrence
of any of the following items of Indebtedness (collectively, "Permitted
Indebtedness"):

         (a) the incurrence by the Company of additional Indebtedness and
letters of credit under Credit Facilities in an aggregate principal amount at
any one time outstanding under this clause (a)(with letters of credit being
deemed to have a principal amount equal to the maximum potential liability of
the Company and its Subsidiaries thereunder) not to exceed $400 million;

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

         (c) the incurrence by the Company of:

             (1)          Indebtedness represented by the Notes and the Exchange
                          Notes and the related Subsidiary Guarantees, if any,
                          to be issued pursuant to the Registration Rights
                          Agreement; and

             (2)          Indebtedness represented by the Convertible Senior
                          Notes;

         (d) the incurrence by the Company or any of its Restricted Subsidiaries
of Indebtedness represented by Capital Lease Obligations, mortgage financings or
purchase money obligations, in each case, incurred for the purpose of financing
all or any part of the purchase price or cost of construction or improvement of
property, plant or equipment used in the business of the Company or such
Restricted Subsidiary, in an aggregate principal amount, including all

                                       49
<PAGE>   55

Permitted Refinancing Indebtedness incurred to refund, refinance or replace any
Indebtedness incurred pursuant to this clause (d), not to exceed $15.0 million
at any time outstanding;

         (e) Indebtedness of a Restricted Subsidiary of the Company incurred and
outstanding on or prior to the date on which such Restricted Subsidiary was
acquired by the Company or another Restricted Subsidiary (other than
Indebtedness incurred in connection with, or to provide all or any portion of
the funds or credit support utilized to consummate, the transaction or series of
related transactions pursuant to which such Restricted Subsidiary became a
Restricted Subsidiary or was acquired by the Company or other Restricted
Subsidiary); provided, however, that on the date of such acquisition, after
giving pro forma effect thereto and any related transactions as if the same had
occurred at the beginning of the applicable four-quarter period, the Company
would be permitted to incur at least $1.00 of additional indebtedness pursuant
to the Fixed Charge Coverage Ratio test set forth in the first paragraph of this
Section 4.09;

         (f) the incurrence by the Company or any of its Restricted Subsidiaries
of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of
which are used to refund, refinance or replace Indebtedness (other than
intercompany Indebtedness) that was permitted by this Indenture to be incurred
under the first paragraph of this covenant or clauses (b), (c), (d), (e) or (k)
of this paragraph;

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

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

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

         (h) the incurrence by the Company or any of its Restricted Subsidiaries
of Hedging Obligations that are incurred for the purpose of fixing or hedging
interest rate risk with respect to any floating rate Indebtedness that is
permitted by the terms of this Indenture to be outstanding or for the purpose of
fixing or hedging currency exchange rate risk with respect to any currency
exchanges;

         (i) the guarantee by the Company or any of the Restricted Subsidiaries
of Indebtedness of the Company or a Restricted Subsidiary of the Company that
was permitted to be incurred by another provision of this Section 4.09;

                                       50
<PAGE>   56

         (j) the accrual of interest, the accretion or amortization of original
issue discount, the payment of interest on any Indebtedness in the form of
additional Indebtedness with the same terms, and the payment of dividends on
Disqualified Stock in the form of additional shares of the same class of
Disqualified Stock shall not be deemed to be an incurrence of Indebtedness or an
issuance of Disqualified Stock for purposes of this Section 4.09; provided, in
each such case, that the amount thereof is included in Fixed Charges of the
Company as accrued interest or dividends; and

         (k) the incurrence by the Company or any of its Restricted Subsidiaries
of additional Indebtedness in an aggregate principal amount (or accreted value,
as applicable) at any time outstanding, including all Permitted Refinancing
Indebtedness incurred to refund, refinance or replace any Indebtedness incurred
pursuant to this clause (k), not to exceed $20 million.

         For purposes of determining compliance with this Section 4.09, if an
item of proposed Indebtedness meets the criteria of more than one of the
categories of Permitted Indebtedness described in clauses (a) through (k) above,
or is entitled to be incurred pursuant to the first paragraph of this Section
4.09, the Company shall be permitted to classify such item of Indebtedness on
the date of its incurrence, in any manner that complies with this Section 4.09
and an item of Indebtedness may be divided and classified in more than one of
the types of Indebtedness described above. Indebtedness under Credit Facilities
outstanding on the date on which Notes are first issued and authenticated under
this Indenture shall be deemed to have been incurred on such date in reliance on
the exception provided by clause (a) of the definition of Permitted
Indebtedness.

Section 4.10. Asset Sales.

         Until such time as the Company meets the Rating Condition, the Company
shall not, and shall not permit any of its Restricted Subsidiaries to,
consummate an Asset Sale unless:

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

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

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

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

                                       51
<PAGE>   57

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

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

         (a) to repay Senior Debt and, if the Senior Debt repaid is revolving
credit Indebtedness, to correspondingly reduce commitments with respect thereto;

         (b) to acquire all or substantially all of the assets of, or a majority
of the Voting Stock of, a Permitted Business so long as such Permitted Business
is or becomes a Restricted Subsidiary;

         (c) to make a capital expenditure; or

         (d) to acquire or obtain other long-term assets that are used or useful
in a Permitted Business.

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

         Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the two preceding paragraphs shall constitute "Excess Proceeds."
When the aggregate amount of Excess Proceeds exceeds $10 million, the Company
shall make an Asset Sale Offer to all Holders of Notes and all holders of other
Indebtedness that is pari passu with the Notes containing provisions similar to
those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets to purchase the maximum principal amount of
Notes and such other pari passu Indebtedness that may be purchased out of the
Excess Proceeds. The offer price for the Notes in any Asset Sale Offer shall be
equal to 100% of principal amount plus accrued and unpaid interest and Special
Interest, if any, to the date of purchase, and shall be payable in cash. If any
Excess Proceeds remain after consummation of an Asset Sale Offer, the Company
may use those Excess Proceeds for any purpose not otherwise prohibited by this
Indenture. If the aggregate principal amount of Notes and other pari passu
Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Trustee shall select the Notes and such other pari passu
Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset
Sale Offer, the amount of Excess Proceeds shall be reset at zero.

         The Company shall comply with the requirements of Rule l4e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with each
repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the Asset Sale
provisions of this Indenture, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under the Asset Sale provisions of this Indenture by virtue of such
conflict.

Section 4.11. Transactions with Affiliates.

         Until such time as the Company meets the Rating Condition, the Company
shall not, and shall not permit any of its Restricted Subsidiaries to, make any
payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any transaction, contract, agreement, understanding, loan,
advance or guarantee with, or for the benefit of, any Affiliate (each, an
"Affiliate Transaction"), unless:

         (a) the Affiliate Transaction is on terms that are no less favorable to
the Company or the relevant Restricted Subsidiary than those that would have
been obtained in a comparable transaction by the Company or such Restricted
Subsidiary with an unrelated Person; and

         (b) The Company delivers to the Trustee:

                  (i) with respect to any Affiliate Transaction or series of
         related Affiliate Transactions involving aggregate payments or value
         equal to or greater than $5.0 million, an Officer's Certificate
         certifying that such Affiliate Transaction complies with this covenant;
         and

                  (ii) with respect to any Affiliate Transaction or series of
         related Affiliate Transactions involving aggregate consideration in
         excess of $10 million, an Officer's Certificate certifying that such
         transaction or transactions has been approved by a majority of the
         disinterested members of the Board of Directors of the Company;

         provided, that the Company shall not be required to comply with this
         clause (ii) in connection with the transactions in the ordinary course
         of business between the Company or one of its Restricted Subsidiaries
         with any of Daihatsu-Briggs & Stratton., Ltd., Starting USA
         Corporation, or Metal Technologies Holding Company, Inc.

         The following items shall not be deemed to be Affiliate Transactions
and, therefore, shall not be subject to the provisions of the prior paragraph:

         (a) any employment agreement entered into by the Company or any of its
Restricted Subsidiaries in the ordinary course of business and consistent with
the past practice of the Company or such Restricted Subsidiary;

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

         (c) transactions with a Person that is an Affiliate of the Company
solely because the Company controls such Person;

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

         (e) sales of Equity Interests (other than Disqualified Stock) to
Affiliates of the Company; and

                                       53
<PAGE>   59

         (f) Restricted Payments that are permitted by Section 4.07.

Section 4.12. Liens.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly create, incur, assume or suffer to exist
any Lien of any kind securing Indebtedness, or trade payables on any asset now
owned or hereafter acquired without causing the Notes (and, at the Company's
election, any other outstanding or future Indebtedness of the Company or any of
its Restricted Subsidiaries which is not subordinated to the Notes) to be
secured equally and ratably with (or prior to) that Indebtedness, provided,
however, this restriction will not apply to the following Liens:

         (a) Liens on property, shares of capital stock or indebtedness of any
corporation existing at the time it becomes a Restricted Subsidiary;

         (b) Liens on property, shares of capital stock or indebtedness existing
at the time it is acquired by the Company or any Restricted Subsidiary or within
the 180 day period following that acquisition;

         (c) Liens on property, shares of capital stock or indebtedness acquired

completion of construction or commencement of commercial operation;

         (d) Liens in favor of the Company or any Restricted Subsidiary;

<PAGE>   60

         (k) Liens which arise out of judgments or awards against the Company or
any Restricted Subsidiary pending appeal or review so long as the Liens are
subject to a stay of execution pending that appeal or review;

         (l) Liens for taxes not yet subject to penalties for nonpayment or the
amount or validity of which is being contested in good faith by the Company or
any Restricted Subsidiary;

         (m) Liens which relate to minor survey exceptions, minor encumbrances,
easements or reservations for rights of way and utilities, or zoning or other

not, in the opinion of the Company, materially detract from the value of the
affected properties or materially impair their use in the operation of the
Company's business;

         (n) Liens incurred to finance all or any portion of the cost of

Liens described in clauses (a) through (o) above; or

         (q) Liens securing Indebtedness of the Company and its Restricted
Subsidiaries and Liens in connection with Sale and Leaseback Transactions,
provided that at the time of the incurrence of such Indebtedness or the entering
into of such Sale and Leaseback Transaction, the aggregate amount of
Indebtedness, including Attributable Debt (other than Indebtedness secured by
Liens described in clauses (a) through (o) above and other than Attributable
Debt described in clauses (a) through (f) under Section 4.17), of the Company
and its Restricted Subsidiaries secured by Liens does not exceed 15% of
Consolidated Net Tangible Assets of the Company.

Section 4.13. Payments for Consent.

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

Section 4.14. Corporate Existence.

         Subject to Article 5 and Section 10.05, the Company shall do or cause
to be done all things necessary to preserve and keep in full force and effect
(i) its corporate existence, and the corporate, partnership or other existence
of each of its Restricted Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of the
Company or any such Restricted Subsidiary and (ii) the rights (charter and
statutory), licenses and franchises of the Company and its Restricted
Subsidiaries; provided, however, that

                                       55
<PAGE>   61

the Company shall not be required to preserve any such right, license or
franchise, or the corporate, partnership or other existence of any of the
Company's Restricted Subsidiaries, if the Board of Directors of the Company
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and its Restricted Subsidiaries, taken as
a whole, and that the loss thereof is not adverse in any material respect to the
Holders of the Notes.

Section 4.15. Change of Control.

         If a Change of Control occurs, each Holder of Notes shall have the
right to require the Company to repurchase all or any part (equal to $1,000 or
an integral multiple of $1,000) of that Holder's Notes pursuant to the offer
described below (the "Change of Control Offer") on the terms set forth in this
Indenture. In the Change of Control Offer, the Company shall offer a payment (a
"Change of Control Payment") in cash equal to 101% of the aggregate principal
amount of Notes repurchased plus, in each case, accrued and unpaid interest and
Special Interest, if any, on the Notes repurchased, to the date of purchase.
Within ten days following any Change of Control, the Company shall mail a notice
to each Holder describing the transaction or transactions that constitute the
Change of Control and offering to repurchase Notes on the purchase date
specified in the notice, which date shall be no earlier than 30 days and no
later than 60 days from the date such notice is mailed (the "Change of Control
Payment Date"), pursuant to the procedures required by this Indenture and
described in such notice. The Company shall comply with the requirements of Rule
l4e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent those laws and regulations are applicable in connection
with the repurchase of the Notes as a result of a Change of Control. To the
extent that the provisions of any securities laws or regulations conflict with
the Change of Control provisions of this Indenture, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under the Change of Control provisions of this
Indenture by virtue of such conflict.

         On the Change of Control Payment Date, the Company shall, to the extent
lawful:

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

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

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

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

                                       56
<PAGE>   62

         The provisions in this Section 4.15 that require the Company to make a
Change of Control Offer following a Change of Control shall be applicable
whether or not any other provisions of this Indenture are applicable.

         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

Company and purchases all Notes properly tendered and not withdrawn under the
Change of Control Offer.

Section 4.16. Restrictions on Indebtedness of Restricted Subsidiaries.

         After such time as the Company meets the Rating Condition, the Company

                  Indebtedness for working capital purposes if after giving
                  effect to such incurrence, the aggregate outstanding principal
                  amount of all such Indebtedness of Restricted Subsidiaries of
                  the Company does not exceed $25.0 million.

         In addition, this restriction shall not prohibit the incurrence of
Indebtedness in connection with any initial or successive extension, renewal,
refinancing, replacement or refunding, in whole or in part, of any Indebtedness
of the Restricted Subsidiaries, so long as there is no increase in the principal
amount of the Indebtedness (or, in the case of a revolving credit facility, the
commitment in effect thereunder).

Section 4.17. Sale and Leaseback Transactions.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any Sale and Leaseback Transaction; provided that

         (a) the Company or any Restricted Subsidiary would be permitted to
create a Lien pursuant to clauses (a) through (p) under Section 4.12 on the

equally and ratably securing the Notes;

         (b) within 270 days after the Sale and Leaseback Transaction the
Company or any Restricted Subsidiary prepays Secured Indebtedness held by
persons other than the Company and any Restricted Subsidiary (which prepayments
may not be at maturity or pursuant to mandatory

                                       57
<PAGE>   63

prepayment or sinking fund provisions) in an amount equal to the greater of the
net proceeds of the Sale and Leaseback Transaction or the fair market value of
the property subject to the Sale and Leaseback Transaction at the time of the
transaction (as determined by the chief executive officer, president, chief
financial officer, treasurer or controller of the Company);

         (c) within 270 days after the Sale and Leaseback Transaction the
Company or any Restricted Subsidiary invests the proceeds of the Sale and
Leaseback Transaction in other property, but only if the investment does not
exceed the costs incurred by the Company or any Restricted Subsidiary for
acquiring, repairing, altering or constructing the other property, less the
amount of any purchase money or construction mortgage on that property;

         (d) the effective date of the Sale and Leaseback Transaction is within
270 days of the acquisition of the property or, if later, the completion of
construction and commencement of operation of the property;

the Company and its Restricted Subsidiaries secured by Liens does not exceed 15%
of Consolidated Net Tangible Assets of the Company.

Section 4.18. Subsidiary Guarantees.

         If at any time a Domestic Subsidiary constitutes a Significant Domestic
Subsidiary, then such Domestic Subsidiary shall become a Guarantor and execute a
supplemental indenture and deliver an Opinion of Counsel satisfactory to the
Trustee within 10 Business Days of the date when such event occurs. These
Subsidiary Guarantees shall be joint and several obligations of the Guarantors;
provided, however, that the obligations of each Guarantor under its Subsidiary
Guarantee shall be limited as necessary to prevent that Subsidiary Guarantee
from constituting a fraudulent conveyance under applicable law.

Section 4.19. Limitation on Designation of Unrestricted Subsidiaries.

         Until such time as the Company meets the Rating Condition, the Company
may designate after the date the Notes are issued any Restricted Subsidiary as
an "Unrestricted Subsidiary" under this Indenture (a "Designation") only if:

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

         (2)      the Company would be permitted to make an Investment (other
                  than a Permitted Investments, except a Permitted Investment
                  covered by clause (8) or (9) of the

                                       58
<PAGE>   64

                  definition thereof) at the time of Designation (assuming the
                  effectiveness of such Designation) pursuant to the first
                  paragraph of Section 4.07 in an amount (the "Designation
                  Amount") equal to the Fair Market Value of the Company's
                  interest in such Subsidiary on such date calculated in
                  accordance with GAAP; and

         (3)      the Company would be permitted under this Indenture to incur
                  $1.00 of additional Indebtedness (other than Permitted
                  Indebtedness) pursuant to Section 4.09 at the time of such
                  Designation (assuming the effectiveness of such Designation).

         In the event of any such Designation, the Company shall be deemed to
have made an Investment constituting a Restricted Payment pursuant to Section
4.07 for all purposes of this Indenture in the Designation Amount.

         The Company shall not, and shall not cause or permit any Restricted
Subsidiary to, at any time:

         (1)      provide credit support for or subject any of its property or
                  assets (other than the Capital Stock of any Unrestricted
                  Subsidiary) to the satisfaction of, any Indebtedness of any
                  Unrestricted Subsidiary (including any undertaking, agreement
                  or instrument evidencing such Indebtedness);

         (2)      be directly or indirectly liable for any Indebtedness of any
                  Unrestricted Subsidiary; or

         (3)      be directly or indirectly liable for any Indebtedness which
                  provides that the Holder thereof may (upon notice, lapse of
                  time or both) declare a default thereon or cause the payment
                  thereof to be accelerated or payable prior to its final
                  scheduled maturity upon the occurrence of a default with
                  respect to any Indebtedness of any Unrestricted Subsidiary
                  (including any right to take enforcement action against such
                  Unrestricted Subsidiary), except any non-recourse guarantee
                  given solely to support the pledge by the Company or any
                  Restricted Subsidiary of the Capital Stock of an Unrestricted
                  Subsidiary.

All Subsidiaries of Unrestricted Subsidiaries shall automatically be deemed to
be Unrestricted Subsidiaries.

         The Company may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") if:

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

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

                                       59
<PAGE>   65

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

Section 4.20. Notification that Company meets the Rating Condition.

         If at any time after the date of this Indenture the Notes are rated
Investment Grade and no Event of Default or Default shall have occurred and be
continuing, the Company may deliver to the Trustee an Officer's Certificate
stating that the Company has met the Rating Condition. Following receipt by the
Trustee of such Officer's Certificate, the Company shall no longer be required
to comply with Section 4.07, 4.08, 4.09, 4.10, 4.11, 4.13, 4.19 or 5.01(d).

                                   ARTICLE 5.

Restricted Subsidiaries taken as a whole, in one or more related transactions,
to another Person; unless:

transfer, conveyance or other disposition has been made assumes all the
obligations of the Company under the Notes, this Indenture and the Registration
Rights Agreement pursuant to agreements reasonably satisfactory to the Trustee;

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

         (d) if such consolidation, merger, sale, assignment, transfer,
conveyance or other disposition occurs before the Rating Condition is met, the
Company or the Person formed by or surviving any such consolidation or merger

conveyance or other disposition has been made:

         transaction equal to or greater than the Consolidated Net Worth of the
         Company immediately preceding the transaction; and

                  (ii) shall, on the date of such transaction after giving pro

the Company and any of its Restricted Subsidiaries which are Guarantors.

Section 5.02. Successor Person Substituted.

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

Restricted Subsidiaries) whether such Indebtedness or guarantee now exists, or
is created after the date of this Indenture, if that default:

                                       61
<PAGE>   67

                  (i) is caused by a failure to pay when due (including any
         grace period set forth in writing in the instruments governing such
         Indebtedness) principal of, or premium, if any, or interest or Special
         Interest, if any on such Indebtedness (a "Payment Default"); or

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

and, in each case, the principal amount of any such Indebtedness, together with
the principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates $10
million or more;

         (f) failure by the Company or any of its Restricted Subsidiaries to pay
final judgments aggregating in excess of $10 million, which judgments are not
paid, discharged or stayed for a period of 60 days;

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

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

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

         Restricted Subsidiaries;

         and the order or decree remains unstayed and in effect for 60
         consecutive days.

Section 6.02. Acceleration.

         In the case of an Event of Default arising under clause (h) or (i) of
Section 6.01 with respect to the Company, any Restricted Subsidiary that is a
Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together, would constitute a Significant Subsidiary, all outstanding Notes
shall, ipsotfacto become due and payable immediately without further action or
notice. If any other Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in aggregate principal amount of the then
outstanding Notes may declare all the Notes to be due and payable immediately by
a notice to the Company (and the Trustee if given by the Holders), and upon any
such declaration, such principal and all accrued interest thereon and all
accrued Special Interest, if any, shall become immediately due and payable.

         At any time after a declaration of acceleration with respect to the
Notes, the Holders of a majority in aggregate principal amount of the Notes may
rescind and cancel such declaration and its consequences (i) if the rescission
would not conflict with any judgment or decree, (ii) if all existing Events of
Default have been cured or waived except nonpayment of principal, interest or
Special Interest that has become due solely because of the acceleration, (iii)
if, to the extent the payment of such interest is lawful, interest on overdue
installments of interest and overdue principal as specified in Section 4.01,
which has become due otherwise than by such declaration of acceleration, has
been paid, (iv) if the Company has paid the Trustee its reasonable compensation
and reimbursed the Trustee for its expenses, disbursements and advances and (v)
if, in the event of the cure or waiver of an Event of Default of the type
described in clause (h) or (i) of Section 6.01, the Trustee shall have received
an Officer's Certificate and an Opinion of Counsel that such Event of Default
has been cured or waived. No such rescission shall affect any subsequent Default
or impair any right consequent thereto. If any Event of Default exists solely by
reason of any acceleration of Indebtedness under clause (e) of Section 6.01, and
such acceleration is rescinded by the holders of Indebtedness affected thereby
prior to the time the Obligations under the Notes have been accelerated, such
Event of Default shall cease to exist.

Section 6.03. Other Remedies.

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

         The Trustee may maintain a proceeding with respect to the Notes or this
Indenture even if it does not possess any of the Notes or does not produce any
of them in the proceeding. A delay or omission by the Trustee or any Holder of a
Note in exercising any right or remedy accruing upon an Event of Default shall
not impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04. Waiver of Past Defaults.

         The Holders of a majority in aggregate principal amount of the Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all of
the Notes waive any existing Default or Event of Default and its consequences
under this Indenture except, subject to the second paragraph of Section 6.02, a
continuing Default or Event of Default in the payment of principal,

                                       63
<PAGE>   69

premium, if any, or interest or Special Interest on, the Notes (including in
connection with a repurchase upon a Change of Control) or a Default or Event of
Default with respect to any covenant or provision which cannot be modified or
amended without the consent of the Holder of each Note affected. Upon any such
waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

Section 6.05. Control by Majority.

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

Section 6.06. Limitation on Suits.

         A Holder of a Note may pursue a remedy with respect to this Indenture
or the Notes only if:

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

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

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

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

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

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

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

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and Special Interest,
if any, and interest on the Note, on or after the respective due dates expressed
in the Note, or, in the case of redemption or repurchase, on the Redemption Date
or the repurchase date, as the case may be, including in connection with an
offer to purchase, or to bring suit for the enforcement of any such payment on

                                       64
<PAGE>   70

or after such respective dates, shall not be impaired or affected without the
consent of such Holder.

Section 6.08. Collection Suit by Trustee.

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

Section 6.09. Trustee May File Proofs of Claim.

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

Section 6.10. Priorities.

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

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

         Second: to Holders of Notes for amounts due and unpaid on the Notes for
principal, premium, if any, and interest, and Special Interest, if any, ratably,

principal, premium and interest, and Special Interest, if any, respectively; and

         Third: to the Company, the Guarantors or to such other party as a court

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

                                     TRUSTEE

Section 7.01. Duties of Trustee.

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

         (b) Except during the continuance of an Event of Default actually known
to the Trustee:

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

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

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

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

                                       66
<PAGE>   72

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

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

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

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

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

Section 7.02. Rights of Trustee.

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

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

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

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

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

Section 7.03. Individual Rights of Trustee.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in accordance with the requirements of the TIA, in the event
that the Trustee acquires any conflicting interest it must eliminate such
conflict within 90 days, apply to the SEC for permission to continue as Trustee
(in the event such conflict arises after the consummation of the Exchange Offer,
or if a Shelf Registration Statement has been filed, after such Shelf
Registration Statement has been declared effective by the SEC) or resign. Any
Agent may do the same with like rights and duties. The Trustee is also subject
to Sections 7.10 and 7.11.

Section 7.04. Trustee's Disclaimer.

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

Section 7.05. Notice of Defaults.

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

Section 7.06. Reports by Trustee to Holders of the Notes.

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

         A copy of each report at the time of its mailing to the Holders of
Notes shall be mailed to the Company and if such report is prepared after the
Exchange Registration Statement or Shelf Registration Statement has been
declared effective by the SEC, filed with the SEC and each stock exchange on
which the Notes are listed in accordance with TIA ss.313(d). The Company shall
promptly notify the Trustee when the Notes are listed on any stock exchange and
of any delisting thereof.

                                       68

Section 7.07. Compensation and Indemnity.

         The Company shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
Trustee of an express trust. The Company and the Guarantors, if any, shall
reimburse the Trustee promptly upon request for all reasonable disbursements,
advances and expenses incurred or made by it in addition to the compensation for
its services except any disbursements, expenses and advances as may be
attributable to the Trustee's negligence or willful misconduct. Such expenses
shall include the reasonable compensation, disbursements and expenses of the
Trustee's agents and counsel.

         The Company and the Guarantors, if any, shall indemnify the Trustee
against any and all losses, liabilities or expenses incurred by it arising out
of or in connection with the acceptance or administration of its duties under
this Indenture, including the costs and expenses of enforcing this Indenture
against the Company (including this Section 7.07) and defending itself against
any claim (whether asserted by the Company, the Guarantors or any Holder or any
other person) or liability in connection with the exercise or performance of any
of its powers or duties hereunder, except to the extent any such loss, liability
or expense may be attributable to its negligence or bad faith. The Trustee shall
notify the Company and the Guarantors promptly of any claim for which it may
seek indemnity. Failure by the Trustee to so notify the Company and the
Guarantors shall not relieve the Company or the Guarantors of their obligations
hereunder. The Company and the Guarantors shall defend the claim and the Trustee
shall cooperate in the defense. The Trustee may have separate counsel and the
Company and the Guarantors shall pay the reasonable fees and expenses of such
counsel. The Company and the Guarantors need not pay for any settlement made
without their consent, which consent shall not be unreasonably withheld.

         The obligations of the Company and the Guarantors to the Trustee under
this Section 7.07 shall survive the resignation or removal of the Trustee and
the termination, satisfaction and discharge of this Indenture.

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

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

         As to notice of Liens or charges, the Trustee shall comply with the
provisions of TIA ss. 313(b)(2) to the extent applicable.

Section 7.08. Replacement of Trustee.

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

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

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

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

         (c) a Custodian or public officer takes charge of the Trustee or its
property; or

         (d) the Trustee becomes incapable of acting.

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

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

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

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

Section 7.09. Successor Trustee by Merger, etc.

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

Section 7.10. Eligibility; Disqualification.

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

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

Section 7.11. Preferential Collection of Claims Against Company.

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

                                   ARTICLE 8.
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

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

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

Section 8.02. Legal Defeasance and Discharge.

         The Company may, at its option and at any time, elect to have all of
its obligations discharged with respect to the outstanding Notes and all
obligations of the Guarantors discharged with respect to their Subsidiary
Guarantees ("Legal Defeasance") except for:

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

         (b) the Company's obligations with respect to the Notes concerning
issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or
stolen Notes and the maintenance of an office or agency for payment and money
for security payments held in trust;

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

                                       71
<PAGE>   77

         (d) the Legal Defeasance provisions of this Indenture.

         For this purpose, Legal Defeasance means that the Company shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.05 and the other Sections of this Indenture described
in (a) and (b) above, and to have satisfied all its other obligations under such
Notes and this Indenture (and the Trustee, on demand of and at the expense of
the Company, shall execute proper instruments acknowledging the same), except
for the above provisions. Subject to compliance with this Article 8, the Company
may exercise its option under this Section 8.02 notwithstanding the prior
exercise of its option under Section 8.03.

Section 8.03. Covenant Defeasance.

         Upon the Company's exercise under Section 8.01 of the option applicable
to this Section 8.03, the Company and the Guarantors, if any, shall, subject to
the satisfaction of the conditions set forth in Section 8.04, be released from
their obligations under Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13,
4.15, 4.16, 4.17, 4.18, 4.19, 5.01 and Article 10 with respect to the
outstanding Notes on and after the date the conditions set forth in Section 8.04
are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall
thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Notes shall not be deemed outstanding for accounting purposes). For this
purpose, Covenant Defeasance means that, with respect to the outstanding Notes,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.01, but, except as
specified above, the remainder of this Indenture and such Notes shall be
unaffected thereby. In addition, upon the Company's exercise under Section 8.01
of the option applicable to this Section 8.03, subject to the satisfaction of
the conditions set forth in Section 8.04, Sections 6.01(c) through 6.01(f) shall
not constitute Events of Default.

Section 8.04. Conditions to Legal or Covenant Defeasance.

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

         In order to exercise either Legal Defeasance or Covenant Defeasance:

         (a) the Company must irrevocably deposit with the Trustee, in trust,
for the benefit of the Holders of Notes, cash in United States dollars,
non-callable Government Securities, or a combination of cash in United States
dollars and non-callable Government Securities, in amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, or interest and premium and Special
Interest, if any, on the

                                       72
<PAGE>   78

outstanding Notes on the Stated Maturity or on the applicable Redemption Date,
as the case may be, and the Company must specify whether the Notes are being
defeased to maturity or to a particular Redemption Date;

         (b) in the case of Legal Defeasance, the Company shall have delivered
to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee
confirming that (A) the Company has received from, or there has been published
by, the Internal Revenue Service a ruling or (B) since the date of this
Indenture, there has been a change in the applicable federal income tax law, in
either case to the effect that, and based thereon such Opinion of Counsel will
confirm that, the Holders of the outstanding Notes will not recognize income,
gain or loss for federal income tax purposes as a result of such Legal
Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred;

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

         (d) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit);

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

         (f) the Company shall have delivered to the Trustee an Officer's
Certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders of Notes over the other creditors of the Company with
the intent of defeating, hindering, delaying or defrauding creditors of the
Company or others; and

         (g) the Company shall have delivered to the Trustee an Officer's
Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance have been
complied with.

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

         Subject to Section 8.06, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying Trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 in respect of the outstanding Notes shall be
held in trust and applied by the Trustee, in accordance with the provisions of
such Notes and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to

                                       73
<PAGE>   79

the Holders of such Notes of all sums due and to become due thereon in respect
of principal, premium, if any, and interest and Special Interest, if any, but
such money need not be segregated from other funds except to the extent required
by law.

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

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

Section 8.06. Repayment to Company.

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

Section 8.07. Reinstatement.

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

                                       74
<PAGE>   80

to the rights of the Holders of such Notes to receive such payment from the
money held by the Trustee or Paying Agent.

                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01. Without Consent of Holders of Notes.

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

         (a) to cure any ambiguity, defect, mistake or inconsistency;

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

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

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

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

         (f) to allow any Guarantor to execute a supplemental indenture in
respect of a Subsidiary Guarantee.

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

Section 9.02. With Consent of Holders of Notes.

         Except as provided below in this Section 9.02, this Indenture or the
Notes may be amended or supplemented with the consent of the Holders of at least
a majority in principal amount of the Notes then outstanding (including, without
limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for, Notes), and subject to Sections 6.02, 6.04 and 6.07, any
existing Default or Event of Default (other than a Default or Event of Default
in the payment of principal of, premium, if any, or interest or Special
Interest, if any, on the Notes) or compliance with any provision of this
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding

                                       75
<PAGE>   81

Notes (including, without limitation, consents obtained in connection with a
purchase of, or tender offer or exchange offer for, Notes).

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

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

         After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.02, 6.04 and 6.07, the Holders of a
majority in aggregate principal amount of the Notes then outstanding voting as a
single class may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Notes. However, without the consent of
each Holder affected, an amendment or waiver under this Section 9.02 may not
(with respect to any Notes held by a non-consenting Holder):

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

         (b) reduce the principal of or change the fixed maturity of any Note or
alter or waive any of the provisions with respect to the redemption of the Notes
(other than provisions relating to Section 4.10 or 4.15);

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

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

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

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

                                       76
<PAGE>   82

         (g) waive a redemption payment with respect to any Note (other than a
payment required by Section 4.10 or 4.15);

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

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

Section 9.03. Compliance with Trust Indenture Act.

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

Section 9.04. Revocation and Effect of Consents.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the amendment, supplement or waiver becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders of Notes entitled to consent to any
amendment, supplement or waiver. If a record date is fixed, then notwithstanding
the provisions of the second sentence of the preceding paragraph, those Holders
of Notes who were Holders on such record date (or their duly designated
proxies), and only those Holders, shall be entitled to revoke any consent
previously given, whether or not such Holder of Notes continues to be a Holder
of Notes after such record date.

         After an amendment, supplement or waiver becomes effective, it shall
bind every Holder of Notes, unless it makes a change described in clauses (a)
through (i) of Section 9.02, in which case, the amendment, supplement or waiver
shall bind only each Holder of Notes who has consented to it; provided that any
such waiver shall not impair or affect the right of any Holder to receive
payment of principal of and interest and Special Interest, if any, on the Notes,
on or after the respective due dates expressed in such Notes, or to bring suit
for the enforcement of any such payment on or after such respective dates
without the consent of such Holder of Notes.

Section 9.05. Notation on or Exchange of Notes.

         The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. If an amendment,
supplement or waiver changes the terms of the Notes, the Company may require the
Holders of the Notes to deliver the Notes to the Trustee. The Company may place
an appropriate notation on the Notes and return them to the Holders.
Alternatively, the Company in exchange for all Notes may issue and the Trustee

                                       77
<PAGE>   83

shall authenticate new Notes (accompanied by a notation of the Subsidiary
Guarantees duly endorsed by the Guarantors) that reflect the amendment,
supplement or waiver.

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

Section 9.06. Trustee to Sign Amendments, etc.

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

                                  ARTICLE 10.
                              SUBSIDIARY GUARANTEES

Section 10.01. Guarantee.

         Subject to this Article 10, each of the Guarantors hereby agrees,
jointly and severally, to unconditionally guarantee to each Holder of a Note
authenticated and delivered by the Trustee and to the Trustee and its successors
and assigns, irrespective of the validity and enforceability of this Indenture,
the Notes or the Obligations of the Company hereunder or thereunder, that: (a)
the principal and premium, if any, of and interest and Special Interest, if any,
on the Notes will be promptly paid in full when due, whether at maturity, by
acceleration, redemption, repurchase or otherwise, and interest on the overdue
principal and premium, if any, of and interest and Special Interest, if any, on
the Notes, if any, if lawful, and all other Obligations of the Company to the
Holders or the Trustee hereunder or thereunder will be promptly paid in full or
performed, all in accordance with the terms hereof and thereof; and (b) in case
of any extension of time of payment or renewal of any Notes or any of such other
Obligations, that same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration or otherwise subject, however, to the limitations set
forth in Section 10.02. Failing payment when due of any amount so guaranteed or
any performance so guaranteed for whatever reason, the Guarantors shall be
jointly and severally obligated to pay the same immediately. Each Guarantor
agrees that this is a guarantee of payment and not a guarantee of collection.

         The Guarantors hereby agree that their Obligations hereunder shall be
unconditional, irrespective of the validity, regularity or enforceability of the
Notes or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Notes with respect to any provisions
hereof or thereof, the recovery of any judgment against the Company, any action
to enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims with a court
in the event of insolvency or

                                       78
<PAGE>   84

bankruptcy of the Company, any right to require a proceeding first against the
Company, protest, notice and all demands whatsoever and covenants that this
Subsidiary Guarantee shall not be discharged except by complete performance of
the Obligations contained in the Notes and this Indenture.

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

         Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any Obligations guaranteed
hereby until payment in full of all Obligations guaranteed hereby. Each
Guarantor further agrees that, as between the Guarantors, on the one hand, and
the Holders and the Trustee, on the other hand, (x) the maturity of the
Obligations guaranteed hereby may be accelerated as provided in Article 6 for
the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the Obligations
guaranteed hereby, and (y) in the event of any declaration of acceleration of
such Obligations as provided in Article 6, such Obligations (whether or not due
and payable) shall forthwith become due and payable by the Guarantors for the
purpose of this Subsidiary Guarantee (subject to any subsequent rescission or
cancellation of any acceleration in accordance with Section 6.02). The
Guarantors shall have the right to seek contribution from any non-paying
Guarantor so long as the exercise of such right does not impair the rights of
the Holders under the Subsidiary Guarantee.

Section 10.02. Limitation on Guarantor Liability.

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

Section 10.03. Execution and Delivery of Subsidiary Guarantee.

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

                                       79
<PAGE>   85

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

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

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

         In the event that the Company creates or acquires any new Subsidiaries
subsequent to the date of this Indenture, if required by Section 4.18 hereof,
the Company shall cause such Subsidiaries to execute supplemental indentures to
this Indenture and Subsidiary Guarantees in accordance with Section 4.18 and
this Article 10, to the extent applicable.

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

         Except as otherwise provided in Section 10.05, no Guarantor may (i)
consolidate or merge with or into (whether or not such Guarantor is the
surviving Person) another Person or (ii) sell, assign, transfer, lease, convey
or otherwise dispose of all or substantially all of its properties or assets to
another Person unless:

         (a) subject to Section 10.05 either: (x) the Person formed by or
surviving any such consolidation or merger (if other than a Guarantor or the
Company) or the Person acquiring the property or assets in any such sale,
assignment, transfer, lease, conveyance or other disposition unconditionally
assumes all the Obligations of such Guarantor under the Notes, this Indenture,
its Subsidiary Guarantee and the Registration Rights Agreement, pursuant to a
supplemental indenture in form and substance reasonably satisfactory to the
Trustee, on the terms set forth herein or therein or (y) the Net Proceeds of
such sale, assignment, transfer, lease, conveyance or other disposition are
applied in accordance with the applicable provisions of this Indenture; and

         (b) immediately after giving effect to such transaction, no Default or
Event of Default exists.

         In case of any such consolidation, merger, sale, assignment, transfer,
lease, or conveyance or other disposition and upon the assumption by the
successor Person, by supplemental indenture, executed and delivered to the
Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee
endorsed upon the Notes and the due and punctual performance of all of the
covenants and conditions of this Indenture to be performed by the Guarantor,
such successor Person shall succeed to and be substituted for the Guarantor with
the same effect as if it had been named herein as a Guarantor. Such successor
Person thereupon may cause to be signed any or all of the Subsidiary Guarantees
to be endorsed upon all of the Notes issuable hereunder which theretofore shall
not have been signed by the Company and delivered to the Trustee. All the
Subsidiary Guarantees so issued shall in all respects have the same legal rank
and benefit under this Indenture as the Subsidiary Guarantees theretofore and
thereafter

                                       80
<PAGE>   86

issued in accordance with the terms of this Indenture as though all of such
Subsidiary Guarantees had been issued at the date of the execution hereof.

         Except as set forth in Article 4 and 5, and notwithstanding clauses (a)
and (b) above, nothing contained in this Indenture or in any of the Notes shall
prevent any consolidation or merger of a Guarantor with or into the Company or
another Guarantor, or shall prevent any sale, assignment, transfer, lease,
conveyance or other disposition of all or substantially all of the property or
assets of a Guarantor to the Company or another Guarantor.

Section 10.05. Releases Following Sale of Assets or Designation as an
               Unrestricted Guarantor.

         In the event of (i) a sale, assignment, transfer, lease, conveyance or
other disposition of all or substantially all of the property or assets of any
Guarantor (by way of merger, consolidation or otherwise), or (ii) a sale or
other disposition of all to the Capital Stock of any Guarantor, in each case to
a Person that is not (either before or after giving effect to such transaction)
a Significant Domestic Subsidiary of the Company, then such Guarantor (in the
case of clause (ii)) or the Person acquiring the properties or assets (in the
case of clause (i)) will be released and relieved of any obligations under its
Subsidiary Guarantee; if the transaction described in clause (i) or (ii)
complies with the applicable provisions of this Indenture, including without
limitation Section 4.10. Upon delivery by the Company to the Trustee of an
Officer's Certificate and an Opinion of Counsel to the effect that such
transaction was made by the Company in accordance with the provisions of this
Indenture, including without limitation Section 4.10, the Trustee shall execute
any documents reasonably required in order to evidence the release of any
Guarantor from its obligations under its Subsidiary Guarantee.

         Any Guarantor not released from its obligations under its Subsidiary
Guarantee shall remain liable for the full amount of principal of and premium,
if any, interest and Special Interest, if any, on the Notes and for the other
obligations of any Guarantor under this Indenture as provided in this Article
10.

                                  ARTICLE 11.
                           SATISFACTION AND DISCHARGE

Section 11.01. Satisfaction and Discharge.

         This Indenture will be discharged and will cease to be of further
effect as to all Notes issued hereunder, (except as to any surviving rights of
registration of transfer or exchange) when:

(1)      either:

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

         (b)      all Notes that have not been delivered to the Trustee for
                  cancellation have become due and payable by reason of the
                  mailing of a notice of redemption or otherwise or will become
                  due and payable within one year and the Company or any

                                       81
<PAGE>   87

                  Guarantor has irrevocably deposited or caused to be deposited
                  with the Trustee as trust funds in trust solely for the
                  benefit of the Holders, cash in U.S. dollars, non-callable
                  Government Securities, or a combination of cash in U.S.
                  dollars and non-callable Government Securities, in amounts as
                  will be sufficient without consideration of any reinvestment
                  of interest, to pay and discharge the entire indebtedness on
                  the Notes not delivered to the Trustee for cancellation for
                  principal, premium and Special Interest, if any, and accrued
                  interest to the date of maturity;

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

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

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

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

         Notwithstanding the satisfaction and discharge of this Indenture, if
money shall have been deposited with the Trustee pursuant to subclass (b) of
clause (1) of this Section, the provisions of Section 12.02 and Section 8.06
shall survive.

Section 11.02. Application of Trust Money.

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

         If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 11.01 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's and any Guarantor's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 11.01; provided that if the Company has made any payment of principal
of, premium and Special Interest, if any, or interest on any Notes because of
the reinstatement of its Obligations, the

                                       82
<PAGE>   88

Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money or Government Securities held by the Trustee
or Paying Agent.

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

         1. INTEREST AND SPECIAL INTEREST. Briggs & Stratton Corporation, a
Wisconsin corporation (the "Company"), promises to pay interest on the principal
amount of this Note at 8.875% per annum from May 14, 2001 until maturity and
shall pay the Special Interest payable pursuant to Section 2(c) of the

authenticated between a record date referred to in paragraph 2 and the next
succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be September 15, 2001. The

                                      A-2
<PAGE>   95

Company shall pay interest (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue principal and premium, if any, from time to
time on demand at a rate that is 1% per annum in excess of the interest rate
stated in the first sentence of this paragraph; it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest and Special Interest, if any, (without regard to any
applicable grace period) from time to time on demand at the same rate to the
extent lawful. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

         2. METHOD OF PAYMENT. The Company will pay interest on the Notes
(except defaulted interest) and Special Interest, if any, to the Persons who are
registered Holders of Notes at the close of business on the September 1 or March
1 next preceding the Interest Payment Date, even if such Notes are canceled
after such record date and on or before such Interest Payment Date, except as
provided in Section 2.12 of the Indenture with respect to defaulted interest.
The Notes will be payable as to principal, premium, if any, and interest and
Special Interest, if any, at the office or agency of the Company maintained for
such purpose within or without the City and State of New York, or, at the option
of the Company, payment of interest and Special, if any, Interest may be made by
check mailed to the Holders at their addresses set forth in the register of
Holders, and provided that payment by wire transfer of immediately available
funds will be required with respect to principal of and premium, if any, and
interest and Special Interest, if any, on, all Global Notes and all other Notes
the Holders of which shall have provided wire transfer instructions to the
Company or the Paying Agent. Such payment shall be in such coin or currency of
the United States of America as at the time of payment is legal tender for
payment of public and private debts.

         3. PAYING AGENT AND REGISTRAR. Initially, Bank One, N.A., the Trustee
under the Indenture, will act as Paying Agent and Registrar. The Company may
change any Paying Agent or Registrar without notice to any Holders of the Notes.
The Company or any of its Subsidiaries may act in any such capacity.

         4. INDENTURE. The Company issued the Notes under an Indenture dated May
14, 2001 ("Indenture") between the Company, the Guarantors listed on Schedule 1
thereto and the Trustee. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Notes
are subject to all such terms, and Holders are referred to the Indenture and
such Act for a statement of such terms. To the extent any provision of this Note
conflicts with the express provisions of the Indenture, the provisions of the
Indenture shall govern and be controlling. The Notes are unsecured obligations
of the Company limited to $275,000,000 aggregate principal amount.

         5. OPTIONAL REDEMPTION. The notes may be redeemed in whole at any time
or in part from time to time, at our option, at a redemption price equal to the
greater of:

         (1) 100% of the principal amount of the notes to be redeemed, and

         (2) the sum of the present values of the remaining scheduled payments
of principal and interest on the notes to be redeemed (exclusive of interest
accrued to the Redemption Date) discounted to the Redemption Date on a
semi-annual basis (assuming a 360-year consisting of twelve 30-day months) at
the applicable Treasury Rate plus 50 basis points, plus accrued and unpaid
interest on the principal amount being redeemed to the Redemption Date.

         Except pursuant to the preceding paragraphs, the Notes will not be
redeemable at the Company's option prior to maturity.

                                      A-3
<PAGE>   96

         6. MANDATORY REDEMPTION. Except as set forth in paragraph 7 below, the
Company shall not be required to make mandatory redemption payments, sinking
fund payments or repurchase payments with respect to the Notes.

         7. REPURCHASE AT OPTION OF HOLDER.

         (a) If a Change of Control occurs, each Holder of Notes shall have the
right to require the Company to repurchase all or any part (equal to $1,000 or
an integral multiple of $1,000) of that Holder's Notes pursuant to a Change of
Control Offer on the terms set forth in the Indenture. In the Change of Control
Offer, the Company shall offer a Change of Control Payment in cash equal to 101%
of the aggregate principal amount of Notes repurchased plus, in each case,
accrued and unpaid interest and Special Interest, if any, on the Notes
repurchased, to the date of purchase. Within ten days following any Change of
Control, the Company shall mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Notes on the purchase date specified in the notice, which date
shall be no earlier than 30 days and no later than 60 days from the date such
notice is mailed, pursuant to the procedures required by the Indenture and
described in such notice.

         (b) If the Company or a Restricted Subsidiary consummates any Asset
Sales, within five Business Days of each date on which the aggregate amount of
Excess Proceeds exceeds $10.0 million, the Company shall commence an Asset Sale
Offer pursuant to Section 3.09 of the Indenture to purchase the maximum
principal amount of Notes that may be purchased out of the Excess Proceeds at an
offer price in cash in an amount equal to 100% of the principal amount thereof
plus accrued and unpaid interest and Special Interest, if any, to the date of
purchase, in accordance with the procedures set forth in the Indenture. To the
extent that the aggregate amount of Notes and other pari passu Indebtedness
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company (or such Restricted Subsidiary) may use such deficiency for general
corporate purposes. If the aggregate principal amount of Notes surrendered by
Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes to be purchased on a pro rata basis. Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holder to Elect Purchase "
on the reverse of the Notes.

         8. NOTICE OF REDEMPTION. Notice of redemption will be given at least 30
days but not more than 60 days before the Redemption Date to each Holder whose
Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed. On and
after the Redemption Date (assuming the Company has made the payment due upon
redemption) interest (and Special Interest, if any) ceases to accrue on Notes or
portions thereof called for redemption .

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

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

subject to legal defeasance and covenant defeasance, and the Indenture is
subject to discharge, all as described in the Indenture.

         13. EVENTS OF DEFAULT. If any Event of Default with respect to the
Notes shall occur and be continuing, the principal of all the Notes may be
declared due and payable in the manner and with the effect provided in the
Indenture.

         14. PARTIAL REDEMPTION OR REPURCHASE. In the event of a redemption or
repurchase of this Note in part only, a new Note or Notes for the unredeemed or
unrepurchased portion hereof will be issued in the name of the Holder hereof
upon cancellation hereof.

         15. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform

Company or its Affiliates, as if it were not the Trustee.

         16. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or shareholder, of the Company or any Guarantor, as such, shall not
have any liability for any obligations of the Company or the Guarantors under
the Notes, the Indenture or the Subsidiary Guarantees or for any claim based on,
in respect of, or by reason of, such obligations or their creation. Each Holder
by accepting a Note waives and releases all such liability. The waiver and

                         FORM OF SUPPLEMENTAL INDENTURE
                    TO BE DELIVERED BY SUBSEQUENT GUARANTORS

Wisconsin corporation (the "Company"), the Company, the other Guarantors (as
defined in the Indenture referred to herein) and Bank One, N.A., as trustee
under the indenture referred to below (the "Trustee").

                               W I T N E S S E T H

         WHEREAS, the Company has heretofore executed and delivered to the

the issuance of an aggregate principal amount of up to $275,000,000 of 8.875%
Senior Notes due March 15, 2011 (the "Notes");

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

         WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is

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

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

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

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

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

                (ii) in case of any extension of time of payment or renewal of
            any Notes or any of such other Obligations, that same will be
            promptly paid in full when due or performed in accordance with the
            terms of the extension or renewal, whether at stated maturity, by
            acceleration or otherwise, subject to the limitations set forth in
            the Indenture. Failing payment when due of any amount so guaranteed
            or any performance so

<PAGE>   112

            guaranteed for whatever reason, the Guarantors shall be jointly and
            severally obligated to pay the same immediately.

            (b) The Obligations hereunder shall be unconditional, irrespective
         of the validity, regularity or enforceability of the Notes or the
         Indenture, the absence of any action to enforce the same, any waiver or
         consent by any Holder of the Notes with respect to any provisions
         hereof or thereof, the recovery of any judgment against the Company,
         any action to enforce the same or any other circumstance which might
         otherwise constitute a legal or equitable discharge or defense of
         guarantor.

            (c) The following is hereby waived: diligence, presentment, demand
         of payment, filing of claims with a court in the event of insolvency or
         bankruptcy of the Company, any right to require a proceeding first
         against the Company, protest, notice and all demands whatsoever.

            (d) This Subsidiary Guarantee shall not be discharged except by
         complete performance of the obligations contained in the Notes and the
         Indenture, and the Guaranteeing Subsidiary accepts all obligations of a
         Guarantor under the Indenture.

            (e) If any Holder or the Trustee is required by any court or
         otherwise to return to the Company, the Guarantors, or any Custodian,
         acting in relation to either the Company or the Guarantors, any amount
         paid by either to the Trustee or such Holder, this Subsidiary
         Guarantee, to the extent theretofore discharged, shall be reinstated in
         full force and effect.

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

            (g) As between the Guarantors, on the one hand, and the Holders and
         the Trustee, on the other hand, (x) the maturity of the Obligations
         guaranteed hereby may be accelerated as provided in Article 6 of the
         Indenture for the purposes of this Subsidiary Guarantee,
         notwithstanding any stay, injunction or other prohibition preventing
         such acceleration in respect of the Obligations guaranteed hereby, and
         (y) in the event of any declaration of acceleration of such Obligations
         as provided in Article 6 of the Indenture, such Obligations (whether or
         not due and payable) shall forthwith become due and payable by the
         Guarantors for the purpose of this Subsidiary Guarantee (subject to any
         subsequent rescission or cancellation of any acceleration in accordance
         with Section 6.02 of the Indenture).

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

            (i) Pursuant to Section 10.02 of the Indenture, after giving effect
         to any maximum amount and any other contingent and fixed liabilities
         that are relevant under any applicable Bankruptcy or fraudulent
         conveyance laws, and after giving effect to any collections from,
         rights to receive contribution from or payments made by or on behalf of
         any other Guarantor in respect of the obligations of such other
         Guarantor under Article 10 of the Indenture, this new Subsidiary
         Guarantee shall be limited to the maximum amount permissible such that
         the Obligations of such Guarantor under this Subsidiary Guarantee will
         not constitute a fraudulent transfer or conveyance.

                                      F-2

<PAGE>   113

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

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

            (a) Except as otherwise provided in Section 5(a) below, the
         Guaranteeing Subsidiary may not (i) consolidate or merge with or into
         (whether or not such Guarantor is the surviving Person) or (ii) sell,
         assign, transfer, lease, convey or otherwise dispose of all or
         substantially all of its properties or assets to another Person,
         unless:

                (i) subject to Section 5 below either: (x) the Person formed by
            or surviving any such consolidation or merger (if other than a
            Guarantor or the Company) or the Person acquiring the property or
            assets in any such sale, assignment, transfer, lease, conveyance or
            other disposition, unconditionally assumes all the Obligations of
            such Guarantor under the Notes, the Indenture, its Subsidiary
            Guarantee and the Registration Rights Agreement, pursuant to a
            supplemental indenture in form and substance reasonably satisfactory
            to the Trustee, on the terms set forth herein or therein; or (y) the
            Net Proceeds of such sale, assignment, transfer, lease, conveyance
            or other disposition are applied in accordance with the applicable
            provisions of the Indenture; and

                (ii) immediately after giving effect to such transaction, no
            Default or Event of Default exists.

            (b) In case of any such consolidation, merger, sale, assignment,
         transfer, lease or conveyance or other disposition and upon the
         assumption by the successor Person, by supplemental indenture, executed
         and delivered to the Trustee and satisfactory in form to the Trustee,
         of the Subsidiary Guarantee endorsed upon the Notes and the due and
         punctual performance of all of the covenants and conditions of the
         Indenture to be performed by the Guarantor, such successor Person shall
         succeed to and be substituted for the Guarantor with the same effect as
         if it had been named herein as a Guarantor. Such successor Person
         thereupon may cause to be signed any or all of the Subsidiary
         Guarantees to be endorsed upon all of the Notes issuable hereunder
         which theretofore shall not have been signed by the Company and
         delivered to the Trustee. All the Subsidiary Guarantees so issued shall
         in all respects have the same legal rank and benefit under the
         Indenture as the Subsidiary Guarantees theretofore and thereafter
         issued in accordance with the terms of the Indenture as though all of
         such Subsidiary Guarantees had been issued at the date of the execution
         hereof.

            (c) Except as set forth in Articles 4 and 5 of the Indenture, and
         notwithstanding clauses (a) and (b) above, nothing contained in the
         Indenture or in any of the Notes shall prevent any consolidation or
         merger of a Guarantor with or into the Company or another Guarantor, or
         shall prevent any sale, assignment, transfer, lease or conveyance or
         other disposition of the property or assets of a Guarantor to the
         Company or another Guarantor.

         5. RELEASES.

            (a) In the event of a (i) sale, assignment, transfer, lease,
         conveyance or other disposition of all of the property or assets of any
         Guarantor, by way of merger, consolidation or otherwise, or (ii) a sale
         or other disposition of all to the Capital Stock of any Guarantor, in
         each case to a Person that is not (either before or after giving effect
         to such transaction) a Significant Domestic Subsidiary of the Company,
         then such Guarantor (in the case of clause (ii)) or the

                                      F-3

<PAGE>   114

         Person acquiring the property or assets (in the case of clause (i))
         will be released and relieved of any obligations under its Subsidiary
         Guarantee if the transaction described in clause (i) or (ii) complies
         with the applicable provisions of the Indenture, including without
         limitation Section 4.10 of the Indenture. Upon delivery by the Company
         to the Trustee of an Officer's Certificate and an Opinion of Counsel to
         the effect that such transaction was made by the Company in accordance
         with the provisions of the Indenture, including without limitation
         Section 4.10 of the Indenture, the Trustee shall execute any documents
         reasonably required in order to evidence the release of any Guarantor
         from its obligations under its Subsidiary Guarantee.

            (b) Any Guarantor not released from its obligations under its Note
         Guarantee shall remain liable for the full amount of principal of and
         premium, if any, interest and Special Interest, if any, on the Notes
         and for the other obligations of any Guarantor under the Indenture as
         provided in Article 10 of the Indenture.

         6. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, shareholder or agent of the Guaranteeing
Subsidiary, as such, shall have any liability for any obligations of the Company
or any Guaranteeing Subsidiary under the Notes, any Subsidiary Guarantees, the
Indenture or this Supplemental Indenture or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of the
Notes by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Notes.

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

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

         9. EFFECT OF HEADINGS. The Section headings herein are for convenience
only and shall not affect the construction hereof.

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

                  (c)      The following is hereby waived: diligence,
         presentment, demand of payment, filing of claims with a court in the
         event of insolvency or bankruptcy of the Company, any right to require
         a proceeding first against the Company, protest, notice and all demands
         whatsoever.

                  (d)      This Subsidiary Guarantee shall not be discharged
         except by complete performance of the obligations contained in the
         Notes and the Indenture, and the Guaranteeing Subsidiary accepts all
         Obligations of a Guarantor under the Indenture.

                  (e)      If any Holder or the Trustee is required by any court
         or otherwise to return to the Company, the Guarantors, or any Custodian
         acting in relation to either the Company or the Guarantors, any amount
         paid by either to the Trustee or such Holder, this Subsidiary
         Guarantee, to the extent theretofore discharged, shall be reinstated in
         full force and effect.

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

                  (g)      As between the Guarantors, on the one hand, and the
         Holders and the Trustee, on the other hand, (x) the maturity of the
         Obligations guaranteed hereby may be accelerated as provided in Article
         6 of the Indenture for the purposes of this Subsidiary Guarantee,
         notwithstanding any stay, injunction or other prohibition preventing
         such acceleration in respect of the Obligations guaranteed hereby, and
         (y) in the event of any declaration of acceleration of such
         Obligations as provided in Article 6 of the Indenture, such Obligations
         (whether or not due and payable) shall forthwith become due and payable
         by the Guarantors for the purpose of this Subsidiary Guarantee (subject
         to any subsequent rescission or cancellation of any acceleration in
         accordance with Section 6.02 of the Indenture).

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

                  (i)      Pursuant to Section 10.02 of the Indenture, after
         giving effect to any maximum amount and any other contingent and fixed
         liabilities that are relevant under any applicable Bankruptcy Law or
         fraudulent conveyance laws, and after giving effect to any collections
         from, rights to receive contribution from or payments made by or on
         behalf of any other Guarantor in respect of the Obligations of such
         other Guarantor under Article 10 of the Indenture, this new Subsidiary
         Guarantee shall be limited to the maximum amount permissible such that
         the Obligations of such Guarantor under this Subsidiary Guarantee will
         not constitute a fraudulent transfer or conveyance.

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

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

                  (a)     Except as otherwise provided in Section 5 below, the
         Guaranteeing Subsidiary may not (i) consolidate with or merge with or
         into (whether or not such Guarantor is the surviving Person) another
         Person or (ii) sell, assign, transfer, lease, convey or otherwise
         dispose of all or substantially all of its assets in one or more
         related transactions to another Person unless:

                  (i)  subject to Section 5 below either: (x) the Person formed
                  by or surviving any such consolidation or merger (if other
                  than a Guarantor or the Company) or the Person acquiring the
                  assets in any such sale, assignment, transfer, lease,
                  conveyance or other disposition unconditionally assumes all
                  the Obligations of such Guarantor under the Notes, the
                  Indenture, the Subsidiary Guarantee and the Registration
                  Rights Agreement, pursuant to a supplemental indenture in form
                  and substance reasonably satisfactory to the Trustee, on the
                  terms set forth herein or therein; or (y) the Net Proceeds of
                  such sale, assignment, transfer, lease, conveyance or other
                  disposition are applied in accordance with the applicable
                  provisions of the Indenture; and

                           (ii) immediately after giving effect to such
                  transaction, no Default or Event of Default exists.

                  (b)      In case of any such consolidation, merger, sale,
         assignment, transfer, lease or conveyance and upon the assumption by
         the successor Person, by supplemental indenture, executed and delivered
         to the Trustee and satisfactory in form to the Trustee, of the
         Subsidiary Guarantee endorsed upon the Notes and the due and punctual
         performance of all of the covenants and conditions of the Indenture to
         be performed by the Guarantor, such successor Person shall succeed to
         and be substituted for the Guarantor with the same effect as if it had
         been named herein as a Guarantor. Such successor Person thereupon may
         cause to be signed any or all of the Subsidiary Guarantees to be
         endorsed upon all of the Notes issuable under the Indenture which
         theretofore shall not have been signed by the Company and delivered to
         the Trustee. All the Subsidiary Guarantees so issued shall in all
         respects have the same legal rank and benefit under the Indenture as
         the Subsidiary Guarantees theretofore and thereafter issued in
         accordance with the terms of the Indenture as though all of such
         Subsidiary Guarantees had been issued at the date of the execution
         hereof.

                  (c)      Except as set forth in Articles 4 and 5 of the
                  Indenture, and notwithstanding clauses (a) and (b) above,
                  nothing contained in the Indenture or in any of the Notes
                  shall prevent any consolidation or merger of a Guarantor with
                  or into the Company or another Guarantor, or shall prevent any
                  sale, assignment, transfer, lease or conveyance of all or
                  substantially all of the assets of a Guarantor to the Company
                  or another Guarantor.

         5.       RELEASES.

                  (a)      In the event of (i) a sale or other disposition of
         all or substantially all of the assets of any Guarantor, by way of
         merger, consolidation or otherwise, or (ii) a sale or other disposition
         of all the Capital Stock of any Guarantor, in each case to a Person
         that is not (either before or after giving effect to such transaction)
         a Significant Domestic Subsidiary of the Company, then such Guarantor
         (in the case of clause (ii)) or the

                                      -3-
<PAGE>   4

         Person acquiring the assets (in the case of clause (i)) will be
         released and relieved of any Obligations under its Subsidiary Guarantee
         if the transaction described in clause (i) or (ii) complies with the
         applicable provisions of the Indenture, including without limitation
         Section 4.10 of the Indenture. Upon delivery by the Company to the
         Trustee of an Officer's Certificate and an Opinion of Counsel to the
         effect that such sale or other disposition was made in accordance with
         the provisions of the Indenture, the Trustee shall execute any
         documents reasonably required in order to evidence the release of any
         Guarantor from its Obligations under its Subsidiary Guarantee.

                  (b)      Any Guarantor not released from its obligations under
         its Subsidiary Guarantee shall remain liable for the full amount of
         principal of, premium and Liquidated Damages, if any, and interest on
         the Notes and for the other obligations of any Guarantor under the
         Indenture as provided in Article 10 of the Indenture.

         6.       NO RECOURSE AGAINST OTHERS. No past, present or future
director, officer, employee, incorporator, shareholder or other agent of the
Guaranteeing Subsidiary, as such, shall have any liability for any Obligations
of the Company or any Guarantor under the Notes, any Subsidiary Guarantees, the
Indenture or this Supplemental Indenture or for any claim based on, in respect
of, or by reason of, such Obligations or their creation. Each Holder of the
Notes by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Notes.

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

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

         9.       EFFECT OF HEADINGS. The Section headings herein are for
convenience only and shall not affect the construction hereof.

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

                                      -4-

         IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed and attested, all as of the date first above
