the ratio of (i) the aggregate amount of EBITDA for the period of the most
recent four consecutive fiscal quarters for which internal financial statements
are available prior to the date of such determination to (ii) Consolidated
Interest Expense for such four fiscal quarters; provided, however, that (A) if
the Company or any Restricted Subsidiary has Incurred any Indebtedness since the
beginning of such period that remains outstanding on such date of determination
or if the transaction giving rise to the need to calculate the Consolidated
Coverage Ratio is an Incurrence of Indebtedness, EBITDA and Consolidated
Interest Expense for such period shall be calculated after giving effect on a
pro forma basis to such Indebtedness as if such Indebtedness had been Incurred
on the first day of such period and the discharge of any other Indebtedness
repaid, repurchased, defeased or otherwise discharged with the proceeds of such
new Indebtedness as if such discharge had occurred on the first day of such
period (except that, in making such computation, the amount of Indebtedness
under any revolving credit facility outstanding on the date of such calculation
shall be computed based on (1) the average daily balance of such Indebtedness
(and any Indebtedness under a revolving credit facility replaced by such
Indebtedness) during such four fiscal quarters or such shorter period when such
facility and any replaced facility was outstanding or (2) if such facility was
created after the end of such four fiscal quarters, the average daily balance of
such Indebtedness (and any Indebtedness under a revolving credit facility
replaced by such Indebtedness) during the period from the date of creation of
such facility to the date of the calculation), (B) if the Company or any
Restricted Subsidiary has repaid, repurchased, defeased or otherwise discharged
any Indebtedness since the beginning of such period or if any Indebtedness is to
be repaid, repurchased, defeased or otherwise discharged (in each case other
than Indebtedness Incurred under any revolving credit facility unless such
Indebtedness has been permanently repaid and has not been replaced) on the date
of the transaction giving rise to the need to calculate the Consolidated
Coverage Ratio, EBITDA and Consolidated Interest Expense for such period shall
be calculated on a pro forma basis as if such discharge had occurred on the
first day of such period and as if the Company or such
Restricted Subsidiary has not earned the interest income actually earned during
such period in respect of cash or Temporary Cash Investments used to repay,
repurchase, defease or otherwise discharge such Indebtedness, (C) if since the
beginning of such period the Company or any Restricted Subsidiary shall have
made any Asset Disposition, the EBITDA for such period shall be reduced by an
amount equal to the EBITDA (if positive) directly attributable to the assets
that are the subject of such Asset Disposition 


                                                                               6

for such period or increased by an amount equal to the EBITDA (if negative)
directly attributable thereto for such period and Consolidated Interest Expense
for such period shall be reduced by an amount equal to the Consolidated Interest
Expense directly attributable to any Indebtedness of the Company or any
Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with
respect to the Company and its continuing Restricted Subsidiaries in connection
with such Asset Disposition for such period (or, if the Capital Stock of any
Restricted Subsidiary is sold, the Consolidated Interest Expense for such period
directly attributable to the Indebtedness of such Restricted Subsidiary to the
extent the Company and its continuing Restricted Subsidiaries are no longer
liable for such Indebtedness after such sale), (D) if since the beginning of
such period the Company or any Restricted Subsidiary (by merger or otherwise)
shall have made an Investment in any Restricted Subsidiary (or any Person that
becomes a Restricted Subsidiary) or an acquisition of assets, including any
acquisition of assets occurring in connection with a transaction causing a
calculation to be made hereunder, which constitutes all or substantially all of
an operating unit of a business, EBITDA and Consolidated Interest Expense for
such period shall be calculated after giving pro forma effect thereto (including
the Incurrence of any Indebtedness) as if such Investment or acquisition
occurred on the first day of such period and (E) if since the beginning of such
period any Person (that subsequently became a Restricted Subsidiary or was
merged with or into the Company or any Restricted Subsidiary since the beginning
of such period) shall have made any Asset Disposition or any Investment or
acquisition of assets that would have required an adjustment pursuant to clause
(C) or (D) above if made by the Company or a Restricted Subsidiary during such
period, EBITDA and Consolidated Interest Expense for such period shall be
calculated after giving pro forma effect thereto as if such Asset Disposition,
Investment or acquisition of assets occurred on the first day of such period.
For purposes of this definition, whenever pro forma effect is to be given to an
acquisition of assets, the amount of income or earnings relating thereto and the
amount of Consolidated Interest Expense associated with any Indebtedness
Incurred in connection therewith, the pro forma calculations shall be determined
in good faith by a responsible financial or accounting Officer of the Company,
and such pro forma calculations shall include (A)(x) the savings in cost of
goods sold that would have resulted from using the Company's actual costs for
comparable goods and services during the comparable period and (y) other savings
in cost of goods sold or eliminations of selling, general and administrative
expenses as determined by a responsible financial or accounting Officer of the
Company in good faith in connection with the Company's consideration of such
acquisition and consistent with the Company's experience in acquisitions of
similar assets, less (B) the incremental expenses that would be included in cost
of goods sold and selling, general and administrative expenses that would have
been incurred by the Company in the operation of such acquired assets during
such period. If any Indebtedness bears a floating rate of interest and is being
given pro forma effect, the interest expense on such Indebtedness shall be
calculated as if the rate in effect on the date of determination had been the
applicable rate for the entire period (taking into account any Interest Rate
Agreement applicable to such Indebtedness if such Interest Rate Agreement has a
remaining term as at the date of determination in excess of 12 months).

            "Consolidated Interest Expense" means, for any period, the total

Transaction pursuant to which the Company or any Subsidiary may sell, convey or
otherwise transfer or grant a security interest in any accounts receivable or
related assets of the type specified in the definition of "Qualified Receivables
Transaction" shall not be included in Consolidated Interest Expense; provided

that does not constitute a Qualified Receivables Transaction shall be included
in Consolidated Interest Expense.

            "Consolidated Net Income" means, for any period, the net income of

other Senior Subordinated Notes pursuant to Section 2.07, 2.08, 2.09, 2.10 or

      of, other Senior Subordinated Notes of the same series pursuant to Section

      issue discount" within the meaning of Section 1273 of the Code;

            (4) if applicable, that such Additional Senior Subordinated Notes
      shall be issuable in whole or in part in the form of one or more Global

      the respective depositaries for such Global Senior Subordinated Notes, the
      form of any legend or legends which shall be borne by such Global Senior
      Subordinated Notes in addition to or in lieu of those set forth in Exhibit

      forth in Section 2.3 of the Appendix in which any such Global Senior
      Subordinated Note may be exchanged in whole or in part for Additional
      Senior Subordinated Notes registered, or any transfer of such Global
      Senior Subordinated Note in whole or in part may be registered, in the
      name or names of Persons other than the depositary for such Global Senior
      Subordinated Note or a nominee thereof; and

            (5) if applicable, that such Additional Senior Subordinated Notes

      Subordinated Exchange Notes as set forth in Exhibit B.

            If any of the terms of any Additional Senior Subordinated Notes are
established by action taken pursuant to a resolution of the Board of Directors,
a copy of an appropriate record of such action shall be certified by the
Secretary or any Assistant Secretary of the Company and delivered to the Senior
Subordinated Notes Trustee at or prior to the delivery of the Officers'
Certificate or the indenture supplemental hereto setting forth the terms of the
Additional Senior Subordinated Notes.

            SECTION 2.02. Form and Dating. Provisions relating to the Original
Senior Subordinated Notes, the Additional Senior Subordinated Notes, the Private
Senior Subordinated Exchange Notes and the Senior Subordinated Exchange Notes
are set forth in the Appendix, which is hereby incorporated in and expressly
made a part of this Indenture. The (i) Original Senior Subordinated Notes and
the Senior Subordinated Notes Trustee's certificate of authentication, (ii)
Private Senior Subordinated Exchange Notes and the Senior Subordinated Notes
Trustee's certificate of authentication and (iii) any Additional Senior
Subordinated Notes (if issued as Transfer Restricted Senior Subordinated Notes
(as defined in the Appendix)) and the Senior Subordinated Notes Trustee's
certificate of authentication shall each be substantially in the form of Exhibit
A hereto, which is hereby incorporated in and expressly made a part of this
Indenture. The Senior Subordinated Exchange Notes and any Additional Senior
Subordinated Notes issued other than as Transfer Restricted Senior Subordinated
Notes and the Senior Subordinated Notes Trustee's certificate of authentication
shall each be substantially in the form of Exhibit B hereto, which is hereby
incorporated in and expressly made a part of this Indenture. The Senior
Subordinated Notes may have notations, legends or 


                                                                              25

endorsements required by law, stock exchange rule, agreements to which the
Company or Holdings is subject, if any, or usage (provided that any such
notation, legend or endorsement is in a form acceptable to the Company). Each
Senior Subordinated Note shall be dated the date of its authentication. The
Senior Subordinated Notes shall be issued only in registered form without
coupons and only in denominations of $1,000 and integral multiples thereof.

            SECTION 2.03. Execution and Authentication. One or more Officers
shall sign the Senior Subordinated Notes for the Company by manual or facsimile
signature.

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

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

            The Senior Subordinated Notes Trustee shall authenticate and make
available for delivery Senior Subordinated Notes as set forth in the Appendix.

            The Senior Subordinated Notes Trustee may appoint an authenticating
agent reasonably acceptable to the Company to authenticate the Senior
Subordinated Notes. Any such appointment shall be evidenced by an instrument
signed by a Trust Officer, a copy of which shall be furnished to the Company.
Unless limited by the terms of such appointment, an authenticating agent may
authenticate Senior Subordinated Notes whenever the Senior Subordinated Notes
Trustee may do so. Each reference in this Indenture to authentication by the
Senior Subordinated Notes Trustee includes authentication by such agent. An
authenticating agent has the same rights as any Registrar, Paying Agent or agent
for service of notices and demands.

            SECTION 2.04. Registrar and Paying Agent. The Company shall maintain
an office or agency where Senior Subordinated Notes may be presented for
registration of transfer or for exchange (the "Registrar") and an office or
agency where Senior Subordinated Notes may be presented for payment (the "Paying
Agent"). The Registrar shall keep a register of the Senior Subordinated Notes
and of their transfer and exchange. The Company may have one or more
co-registrars and one or more additional paying agents. The term "Paying Agent"
includes any additional paying agent, and the term "Registrar" includes any
co-registrars. The Company initially appoints the Senior Subordinated Notes
Trustee as (i) Registrar and Paying Agent in connection with the Senior
Subordinated Notes and (ii) the Senior Subordinated Notes Custodian (as defined
in the Appendix) with respect to the Global Senior Subordinated Notes.

            The Company shall enter into an appropriate agency agreement with
any Registrar or Paying Agent not a party to this Indenture, which shall
incorporate the terms of the TIA. The agreement shall implement the provisions
of this Indenture that relate to such agent. The Company shall notify the Senior
Subordinated Notes Trustee of the name and address of any such agent. If the
Company fails to maintain a Registrar or Paying Agent, the Senior Subordinated
Notes Trustee shall act as such and shall be 


                                                                              26

entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically organized Wholly Owned Subsidiaries may act
as Paying Agent or Registrar.

            The Company may remove any Registrar or Paying Agent upon written
notice to such Registrar or Paying Agent and to the Senior Subordinated Notes
Trustee; provided, however, that no such removal shall become effective until
(1) acceptance of an appointment by a successor as evidenced by an appropriate
agreement entered into by the Company and such successor Registrar or Paying
Agent, as the case may be, and delivered to the Senior Subordinated Notes
Trustee or (2) notification to the Senior Subordinated Notes Trustee that the
Senior Subordinated Notes Trustee shall serve as Registrar or Paying Agent until
the appointment of a successor in accordance with clause (1) above. The
Registrar or Paying Agent may resign at any time upon written notice; provided,
however, that the Senior Subordinated Notes Trustee may resign as Paying Agent
or Registrar only if the Senior Subordinated Notes Trustee also resigns as
Senior Subordinated Notes Trustee in accordance with Section 7.08.

            SECTION 2.05. Paying Agent To Hold Money in Trust. Prior to each due
date of the principal and interest on any Senior Subordinated Note, the Company
shall deposit with the Paying Agent (or if the Company or a Subsidiary is acting
as Paying Agent, segregate and hold in trust for the benefit of the Persons
entitled thereto) a sum sufficient to pay such principal and interest when so
becoming due. The Company shall require each Paying Agent (other than the Senior
Subordinated Notes Trustee) to agree in writing that the Paying Agent shall hold
in trust for the benefit of Senior Subordinated Noteholders or the Senior
Subordinated Notes Trustee all money held by the Paying Agent for the payment of
principal of or interest on the Senior Subordinated Notes and shall notify the
Senior Subordinated Notes Trustee of any default by the Company in making any
such payment. If the Company or a Subsidiary of the Company acts as Paying
Agent, it shall segregate the money held by it as Paying Agent and hold it as a
separate trust fund. The Company at any time may require a Paying Agent to pay
all money held by it to the Senior Subordinated Notes Trustee and to account for
any funds disbursed by the Paying Agent. Upon complying with this Section, the
Paying Agent shall have no further liability for the money delivered to the
Senior Subordinated Notes Trustee.

            SECTION 2.06. Senior Subordinated Noteholder Lists. The Senior
Subordinated Notes Trustee shall preserve in as current a form as is reasonably
prac ticable the most recent list available to it of the names and addresses of
Senior Subordinated Noteholders. If the Senior Subordinated Notes Trustee is not
the Registrar, the Company shall furnish, or cause the Registrar to furnish, to
the Senior Subordinated Notes Trustee, in writing at least five Business Days
before each interest payment date and at such other times as the Senior
Subordinated Notes Trustee may request in writing, a list in such form and as of
such date as the Senior Subordinated Notes Trustee may reasonably require of the
names and addresses of Senior Subordinated Noteholders.

            SECTION 2.07. Transfer and Exchange. The Senior Subordinated Notes
shall be issued in registered form and shall be transferable only upon the
surrender of a Senior Subordinated Note for registration of transfer and in
compliance with the Appendix. When a Senior Subordinated Note is presented to
the Registrar with a request to register a transfer, the Registrar shall
register the transfer as requested if the requirements of Section 8-401(a)(l) of
the Uniform Commercial Code are met. When 


                                                                              27

Senior Subordinated Notes are presented to the Registrar with a request to
exchange them for an equal principal amount of Senior Subordinated Notes of
other denominations, the Registrar shall make the exchange as requested if the
same requirements are met. To permit registration of transfers and exchanges,
the Company shall execute and the Senior Subordinated Notes Trustee shall
authenticate Senior Subordinated Notes at the Registrar's request. The Company
may require payment of a sum sufficient to pay all taxes, assessments or other
governmental charges in connection with any transfer or exchange pursuant to
this Section. The Company shall not be required to make and the Registrar need
not register transfers or exchanges of Senior Subordinated Notes selected for
redemption (except, in the case of Senior Subordinated Notes to be redeemed in
part, the portion thereof not to be redeemed) or any Senior Subordinated Notes
for a period of 15 days before a selection of Senior Subordinated Notes to be
redeemed.

            Prior to the due presentation for registration of transfer of any
Senior Subordinated Note, the Company, Holdings, the Senior Subordinated Notes
Trustee, the Paying Agent, and the Registrar may deem and treat the Person in
whose name a Senior Subordinated Note is registered as the absolute owner of
such Senior Subordinated Note for the purpose of receiving payment of principal
of and interest, if any, on such Senior Subordinated Note and for all other
purposes whatsoever, whether or not such Senior Subordinated Note is overdue,
and none of the Company, Holdings, the Senior Subordinated Notes Trustee, the
Paying Agent, or the Registrar shall be affected by notice to the contrary.

            Any Holder of a Global Senior Subordinated Note shall, by acceptance
of such Global Senior Subordinated Note, agree that transfers of beneficial
interest in such Global Senior Subordinated Note may be effected only through a
book-entry system maintained by (i) the Senior Subordinated Noteholder of such
Global Senior Subordinated Note (or its agent) or (ii) any Senior Subordinated
Noteholder of a beneficial interest in such Global Senior Subordinated Note, and
that ownership of a beneficial interest in such Global Senior Subordinated Note
shall be required to be reflected in a book entry.

            All Senior Subordinated Notes issued upon any transfer or exchange
pursuant to the terms of this Indenture will evidence the same debt and will be
entitled to the same benefits under this Indenture as the Senior Subordinated
Notes surrendered upon such transfer or exchange.

            SECTION 2.08. Replacement Senior Subordinated Notes. If a mutilated
Senior Subordinated Note is surrendered to the Registrar or if the Senior
Subordinated Noteholder of a Senior Subordinated Note claims that the Senior
Subordinated Note has been lost, destroyed or wrongfully taken, the Company
shall issue and the Senior Subordinated Notes Trustee shall authenticate a
replacement Senior Subordinated Note if the requirements of Section 8-405 of the
Uniform Commercial Code are met, such that the Senior Subordinated Noteholder
(i) satisfies the Company or the Senior Subordinated Notes Trustee within a
reasonable time after he has notice of such loss, destruction or wrongful taking
and the Registrar does not register a transfer prior to receiving such
notification, (ii) makes such request to the Company or the Senior Subordinated
Notes Trustee prior to the Senior Subordinated Note being acquired by a
protected purchaser as defined in Section 8-303 of the Uniform Commercial Code
(a "protected purchaser") and (iii) satisfies any other reasonable requirements
of the Senior Subordinated Notes Trustee. If required by the Senior Subordinated
Notes Trustee or the Company, such 


                                                                              28

Senior Subordinated Noteholder shall furnish an indemnity bond sufficient in the
judgment of the Senior Subordinated Notes Trustee to protect the Company, the
Senior Subordinated Notes Trustee, the Paying Agent and the Registrar from any
loss that any of them may suffer if a Senior Subordinated Note is replaced. The
Company and the Senior Subordinated Notes Trustee may charge the Senior
Subordinated Noteholder for their expenses in replacing a Senior Subordinated
Note. In the event any such mutilated, lost, destroyed or wrongfully taken
Senior Subordinated Note has become or is about to become due and payable, the
Company in its discretion may pay such Senior Subordinated Note instead of
issuing a new Senior Subordinated Note in replacement thereof.

            Every replacement Senior Subordinated Note is an additional
obligation of the Company.

            The provisions of this Section 2.08 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, lost, destroyed or wrongfully taken Senior
Subordinated Notes.

            SECTION 2.09. Outstanding Senior Subordinated Notes. Senior
Subordinated Notes outstanding at any time are all Senior Subordinated Notes
authenticated by the Senior Subordinated Notes Trustee except for those canceled
by it, those delivered to it for cancelation and those described in this Section
as not outstanding. A Senior Subordinated Note does not cease to be outstanding
because the Company or an Affiliate of the Company holds the Senior Subordinated
Note.

            If a Senior Subordinated Note is replaced pursuant to Section 2.08,
it ceases to be outstanding unless the Senior Subordinated Notes Trustee and the
Company receive proof satisfactory to them that the replaced Senior Subordinated
Note is held by a protected purchaser.

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

            SECTION 2.10. Temporary Senior Subordinated Notes. In the event that
Definitive Senior Subordinated Notes (as defined in the Appendix) are to be
issued under the terms of this Indenture, until such Definitive Senior
Subordinated Notes are ready for delivery, the Company may prepare and the
Senior Subordinated Notes Trustee shall authenticate temporary Senior
Subordinated Notes. Temporary Senior Subordinated Notes shall be substantially
in the form of Definitive Senior Subordinated Notes but may have variations that
the Company considers appropriate for temporary Senior Subordinated Notes.
Without unreasonable delay, the Company shall prepare and the Senior
Subordinated Notes Trustee shall authenticate Definitive Senior Subordinated
Notes and deliver them in exchange for temporary Senior Subordinated Notes upon
surrender of such temporary Senior Subordinated Notes at the office or agency of
the Company, without charge to the Senior Subordinated Noteholder.


                                                                              29

            SECTION 2.11. Cancelation. The Company at any time may deliver
Senior Subordinated Notes to the Senior Subordinated Notes Trustee for
cancelation. The Registrar and the Paying Agent shall forward to the Senior
Subordinated Notes Trustee any Senior Subordinated Notes surrendered to them for
registration of transfer, exchange or payment. The Senior Subordinated Notes
Trustee and no one else shall can cel all Senior Subordinated Notes surrendered
for registration of transfer, exchange, payment or cancelation and deliver
canceled Senior Subordinated Notes to the Company pursuant to written direction
by an Officer. The Company may not issue new Senior Subordinated Notes to
replace Senior Subordinated Notes it has redeemed, paid or delivered to the
Senior Subordinated Notes Trustee for cancelation. The Senior Subordinated Notes
Trustee shall not authenticate Senior Subordinated Notes in place of canceled
Senior Subordinated Notes other than pursuant to the terms of this Indenture.

            SECTION 2.12. Defaulted Interest. If the Company defaults in a
payment of interest on the Senior Subordinated Notes, the Company shall pay the
defaulted interest (plus interest on such defaulted interest at the rate of
91/8% per annum to the extent lawful) in any lawful manner. The Company may pay
the defaulted interest to the Persons who are Senior Subordinated Noteholders on
a subsequent special record date. The Company shall fix or cause to be fixed any
such special record date and payment date to the reasonable satisfaction of the
Senior Subordinated Notes Trustee and shall promptly mail or cause to be mailed
to each Senior Subordinated Noteholder a notice that states the special record
date, the payment date and the amount of defaulted interest to be paid.

            SECTION 2.13. CUSIP Numbers. The Company in issuing the Senior
Subordinated Notes may use "CUSIP" numbers (if then generally in use) and, if
so, the Senior Subordinated Notes Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Senior Subordinated Noteholders; provided,
however, that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Senior Subordinated Notes
or as contained in any notice of a redemption and that reliance may be placed
only on the other identification numbers printed on the Senior Subordinated
Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers.

                                    ARTICLE 3

                                   Redemption

            SECTION 3.01. Notices to Senior Subordinated Notes Trustee. If the
Company elects to redeem Senior Subordinated Notes pursuant to paragraph 5 of
the Senior Subordinated Notes, it shall notify the Senior Subordinated Notes
Trustee in writing of the redemption date and the principal amount of Senior
Subordinated Notes to be redeemed.

            The Company shall give each notice to the Senior Subordinated Notes
Trustee provided for in this Section at least 60 days before the redemption date
unless the Senior Subordinated Notes Trustee consents to a shorter period. Such
notice shall be accompanied by an Officers' Certificate and an Opinion of
Counsel from the Company to the effect that such redemption will comply with the
conditions herein. If fewer than all the Senior Subordinated Notes are to be
redeemed, the record date relating to such 


                                                                              30

redemption shall be selected by the Company and given to the Senior Subordinated
Notes Trustee, which record date shall be not fewer than 15 days after the date
of notice to the Senior Subordinated Notes Trustee. Any such notice may be
canceled at any time prior to notice of such redemption being mailed to any
Senior Subordinated Noteholder and shall thereby be void and of no effect.

            SECTION 3.02. Selection of Senior Subordinated Notes To Be Redeemed.
If fewer than all the Senior Subordinated Notes are to be redeemed, the Senior
Subordinated Notes Trustee shall select the Senior Subordinated Notes to be
redeemed pro rata or by lot. The Senior Subordinated Notes Trustee shall make
the selection from outstanding Senior Subordinated Notes not previously called
for redemption. The Senior Subordinated Notes Trustee may select for redemption
portions of the principal of Senior Subordinated Notes that have denominations
larger than $1,000. Senior Subordinated Notes and portions of them the Senior
Subordinated Notes Trustee selects shall be in amounts of $1,000 or a whole
multiple of $1,000. Provisions of this Indenture that apply to Senior
Subordinated Notes called for redemption also apply to portions of Senior
Subordinated Notes called for redemption. The Senior Subordinated Notes Trustee
shall notify the Company promptly of the Senior Subordinated Notes or portions
of Senior Subordinated Notes to be redeemed.

            SECTION 3.03. Notice of Redemption. At least 30 days but not more
than 60 days before a date for redemption of Senior Subordinated Notes, the
Company shall mail a notice of redemption by first-class mail to each Senior
Subordinated Noteholder of Senior Subordinated Notes to be redeemed at such
Senior Subordinated Noteholder's registered address.

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

            (1) the redemption date;

            (2) the redemption price and the amount of accrued interest to the
      redemption date;

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

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

            (5) if fewer than all the outstanding Senior Subordinated Notes are
      to be redeemed, the certificate numbers and principal amounts of the
      particular Senior Subordinated Notes to be redeemed;

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

            (7) the CUSIP number, if any, printed on the Senior Subordinated
      Notes being redeemed;


                                                                              31

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

            (9) if applicable, that a Change of Control has occurred and the
      circumstances and relevant facts regarding such Change of Control.

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

            SECTION 3.04. Effect of Notice of Redemption. Once notice of
redemption is mailed, Senior Subordinated Notes called for redemption become due
and payable on the redemption date and at the redemption price stated in the
notice. Upon surrender to the Paying Agent, such Senior Subordinated Notes shall
be paid at the redemption price stated in the notice, plus accrued interest, if
any, to the redemption date; provided, however, that if the redemption date is
after a regular record date and on or prior to the interest payment date, the
accrued interest shall be payable to the Senior Subordinated Noteholder of the
redeemed Senior Subordinated Notes registered on the relevant record date.
Failure to give notice or any defect in the notice to any Senior Subordinated
Noteholder shall not affect the validity of the notice to any other Senior
Subordinated Noteholder.

            SECTION 3.05. Deposit of Redemption Price. Prior to 10:00 a.m. on
the redemption date, the Company shall deposit with the Paying Agent (or, if the
Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust)
money sufficient to pay the redemption price of and accrued interest on all
Senior Subordinated Notes to be redeemed on that date other than Senior
Subordinated Notes or portions of Senior Subordinated Notes called for
redemption that have been delivered by the Company to the Senior Subordinated
Notes Trustee for cancelation.

            SECTION 3.06. Senior Subordinated Notes Redeemed in Part. Upon
surrender of a Senior Subordinated Note that is redeemed in part, the Company
shall execute and the Senior Subordinated Notes Trustee shall authenticate for
the Senior Subordinated Noteholder (at the Company's expense) a new Senior
Subordinated Note equal in principal amount to the unredeemed portion of the
Senior Subordinated Note surrendered.

                                    Covenants

            SECTION 4.01. Payment of Senior Subordinated Notes. The Company
shall promptly pay the principal of and interest on the Senior Subordinated
Notes on the dates and in the manner provided in the Senior Subordinated Notes
and in this Indenture. Principal and interest shall be considered paid on the
date due if on such date the Senior Subordinated Notes Trustee or the Paying
Agent holds in accordance with this Indenture money sufficient to pay all
principal and interest then due and the Senior Subordinated Notes Trustee or the
Paying Agent, as the case may be, is not prohibited from paying 


                                                                              32

such money to the Senior Subordinated Noteholders on that date pursuant to the
terms of this Indenture.

            The Company shall pay interest on overdue principal at the rate
specified therefor in the Senior Subordinated Notes, and it shall pay interest
on overdue installments of interest at the same rate to the extent lawful.

            SECTION 4.02. SEC Reports. Notwithstanding that the Company may not
be subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Company shall file with the SEC and provide the Senior Subordinated
Notes Trustee and any Senior Subordinated Noteholder or prospective Senior
Subordinated Noteholder (upon the request of such Senior Subordinated Noteholder
or prospective Senior Subordinated Noteholder) with such annual reports and such
information, documents and other reports as are specified in Sections 13 and
15(d) of the Exchange Act and applicable to a U.S. corporation subject to such
Sections, such information, documents and other reports to be so filed and
provided at the times specified for the filing of such information, documents
and reports under such Sections.

            SECTION 4.03. Limitation on Indebtedness. (a) The Company shall not,
and shall not permit any Restricted Subsidiary to, Incur, directly or
indirectly, any Indebtedness; provided, however, that the Company may Incur
Indebtedness if on the date of such Incurrence and after giving effect thereto
the Consolidated Coverage Ratio would be greater than 2.00:1.00.

            (b) Notwithstanding Section 4.03(a), the Company and its Restricted
Subsidiaries may Incur the following Indebtedness:

            (i) Indebtedness Incurred pursuant to the Credit Agreement or any
      other Credit Facility in an aggregate principal amount at any time
      outstanding not to exceed $400 million;

            (ii) Indebtedness of the Company owed to and held by any Wholly
      Owned Subsidiary or Indebtedness of a Restricted Subsidiary owed to and
      held by the Company or any Wholly Owned Subsidiary; provided, however,
      that (A) any subsequent issuance or transfer of any Capital Stock or any
      other event that results in any such Wholly Owned Subsidiary ceasing to be
      a Wholly Owned Subsidiary or any subsequent transfer of any such
      Indebtedness (except to the Company or a Wholly Owned Subsidiary) shall be
      deemed, in each case, to constitute the Incurrence of such Indebtedness by
      the issuer thereof and (B) if the Company is the obligor on such
      Indebtedness, such Indebtedness is expressly subordinated to the prior
      payment in full in cash of all obligations with respect to the Senior
      Subordinated Notes;

            (iii) Indebtedness (A) represented by the Senior Subordinated Notes
      (not including any Additional Senior Subordinated Notes), (B) outstanding
      on the Closing Date (other than the Indebtedness described in clauses (i)
      and (ii) above), (C) consisting of Refinancing Indebtedness Incurred in
      respect of any Indebtedness described in this clause (iii) (including

      (D) consisting of Guarantees of any Indebtedness permitted under clauses
      (i) and (ii) of this paragraph (b);


                                                                              33

            (iv) (A) Indebtedness of a Restricted Subsidiary Incurred and

      support utilized to consummate, the transaction or series of related
      transactions pursuant to which such Restricted Subsidiary became a
      Subsidiary of or was otherwise acquired by the Company); provided,
      however, if the aggregate amount of all such Indebtedness of all such
      Restricted Subsidiaries would exceed $20 million, that on the date that
      such Restricted Subsidiary is acquired by the Company, the Company would
      have been able to Incur $1.00 of additional Indebtedness pursuant to
      Section 4.03(a) after giving effect to the Incurrence of such Indebtedness
      pursuant to this clause (iv) and (B) Refinancing Indebtedness Incurred by

      Agreements directly related (as determined in good faith by the Company)
      to Indebtedness permitted to be Incurred by the Company and its Restricted
      Subsidiaries pursuant to this Indenture and Currency Agreements Incurred
      in the ordinary course of business;

            (vi) Indebtedness Incurred by the Company or any Restricted
      Subsidiary (including Capitalized Lease Obligations) financing the
      purchase, lease or improvement of property (real or personal) or equipment
      (whether through the direct purchase of assets or the Capital Stock of the
      Person owning such assets), in each case Incurred no more than 180 days
      after such purchase, lease or improvement of such property and any
      Refinancing Indebtedness in respect of such Indebtedness; provided,
      however, that at the time of the Incurrence of such Indebtedness and after
      giving effect thereto, the aggregate principal amount of all Indebtedness
      incurred pursuant to this clause (vi) and then outstanding shall not
      exceed the greater of $25.0 million and 5% of Adjusted Consolidated
      Assets;

            (vii) Indebtedness Incurred by the Company in connection with the
      acquisition of a Related Business and any Refinancing Indebtedness in

      shall not exceed $50.0 million at any one time;

            (viii) Attributable Debt Incurred by the Company in respect of
      Sale/Leaseback Transactions; provided, however, that the aggregate amount
      of Attributable Debt Incurred and outstanding pursuant to this clause
      (viii) shall not exceed $75.0 million at any one time;

            (ix) Indebtedness arising from agreements of the Company or a
      Restricted Subsidiary providing for indemnification, purchase price
      adjustment or similar obligations, in each case, Incurred or assumed in
      connection with the disposition of any business, assets or a Subsidiary,
      other than Guarantees of Indebtedness Incurred by any Person acquiring all
      or any portion of such business, assets or a 


                                                                              34

      Subsidiary for the purpose of financing such acquisition; provided,
      however, that the maximum assumable liability in respect of all such
      Indebtedness shall at no time exceed the gross proceeds actually received
      by the Company and its Restricted Subsidiaries in connection with such
      disposition;

            (x) any Guarantee by the Company of Indebtedness or other
      obligations of any of its Restricted Subsidiaries so long as the

            (xiii) Indebtedness (other than Indebtedness permitted to be
      Incurred pursuant to Section 4.03(a) or any other clause of this Section
      4.03(b)) in an aggregate principal amount on the date of Incurrence that,
      when added to all other Indebtedness Incurred pursuant to this clause
      (xiii) and then outstanding, shall not exceed $50.0 million.

            (c) The Company shall not Incur any Indebtedness if such
Indebtedness is subordinate or junior in ranking in any respect to any Senior
Indebtedness of the Company unless such Indebtedness is Senior Subordinated
Indebtedness of the Company or is expressly subordinated in right of payment to
Senior Subordinated Indebtedness of the Company.

            (d) Notwithstanding any other provision of this Section 4.03, the
maximum amount of Indebtedness that the Company or any Restricted Subsidiary may
Incur pursuant to this Section shall not be deemed to be exceeded solely as a
result of fluctuations in the exchange rates of currencies. For purposes of
determining the outstanding principal amount of any particular Indebtedness
Incurred pursuant to this Section 4.03, (i) Indebtedness permitted by this
Section 4.03 need not be permitted solely by reference to one provision
permitting such Indebtedness but may be permitted in part by one such provision
and in part by one or more other provisions of this Section permitting such

than one of the types of Indebtedness described in this Section, the Company, in
its sole discretion, shall classify or reclassify such Indebtedness and only be
required to include the amount of such Indebtedness in one of such clauses.

shall not, and shall not permit any Restricted Subsidiary, directly or
indirectly, to (i) declare or pay any dividend or make any distribution on or in
respect of its Capital Stock (including any payment in connection with any
merger or consolidation involving the Company) or similar payment to the direct
or indirect holders of its Capital Stock except dividends or distributions
payable solely in its Capital Stock (other than Disqualified Stock) and except
dividends or distributions payable to the Company or another Restricted
Subsidiary (and, if such Restricted Subsidiary has equity holders other 


                                                                              35

            (1) a Default shall have occurred and be continuing (or would result
      therefrom);

            (2) the Company could not Incur at least $1.00 of additional
      Indebtedness under Section 4.03(a); or

            (3) the aggregate amount of such Restricted Payment and all other
      Restricted Payments (the amount so expended, if other than in cash, to be
      determined in good faith by the Board of Directors, whose determination
      shall be conclusive and evidenced by a resolution of the Board of
      Directors) declared or made subsequent to the Closing Date would exceed
      the sum of:

                  (A) 50% of the Consolidated Net Income accrued during the
            period (treated as one accounting period) from the beginning of the
            fiscal quarter immediately following the fiscal quarter during which
            the Closing Date occurs to the end of the most recent fiscal quarter
            for which internal financial statements are available prior to the
            date of such Restricted Payment (or, in case such Consolidated Net

                  (B) the aggregate Net Cash Proceeds or fair market value of
            assets or property received by the Company as a contribution to its
            equity capital or from the issue or sale of its Capital Stock (in
            each case other than Disqualified Stock and Excluded Contributions)
            subsequent to the Closing Date (other than an issuance or sale to
            (x) a Subsidiary of the Company or (y) an employee stock ownership
            plan or other trust established by the Company or any of its

            by a Subsidiary of the Company) subsequent to the Closing Date of
            any Indebtedness or Disqualified Stock of the Company or its
            Restricted Subsidiaries issued after the Closing Date for Capital
            Stock (other than Disqualified Stock) of the Company (less the
            amount of any cash or the fair market value of other property
            distributed by the Company or any Restricted Subsidiary upon such
            conversion or exchange); and


                                                                              36

            advances or other transfers of assets to the Company or any
            Restricted Subsidiary from such Person, (ii) the sale or liquidation

            Investments previously made by the Company or any Restricted
            Subsidiary in such Unrestricted Subsidiary, which amount was
            included in the calculation of the amount of Restricted Payments.

            (b) The provisions of Section 4.04(a) shall not prohibit:

            (i) any Restricted Payment made by exchange for, or out of the
      proceeds of the substantially concurrent sale of, Capital Stock of the
      Company (other than Disqualified Stock and other than Capital Stock issued
      or sold to a Subsidiary of the Company or an employee stock ownership plan
      or other trust established by the Company or any of its Subsidiaries);
      provided, however, that (A) such Restricted Payment shall be excluded in
      the calculation of the amount of Restricted Payments and (B) the Net Cash
      Proceeds from such sale applied in the manner set forth in this clause (i)
      shall be excluded from the calculation of amounts under Section
      4.04(a)(3)(B);

      Company made by exchange for, or out of the proceeds of the substantially
      concurrent sale of, Indebtedness of the Company that is permitted to be
      Incurred pursuant to Section 4.03(b); provided, however, that such

      Restricted Payments;

            (iii) any purchase or redemption of Subordinated Obligations of the
      Company from Net Available Cash to the extent permitted by Section 4.06;

            (viii) any repurchase of Capital Stock deemed to occur upon exercise
      of stock options if such Capital Stock represents a portion of the
      exercise price of such option; provided, however, that such repurchase
      shall be included in the calculation of the amount of Restricted Payments;

            (ix) the payment of any dividend or the making of any distribution

Company, (ii) make any loans or advances to the Company or (iii) transfer any of

      Restricted Subsidiary was acquired by the Company (other than Indebtedness
      Incurred as consideration in, in contemplation of, 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

      or contained in any amendment to an agreement referred to in clause (1) or
      (2) of this Section 4.05 or this clause (3); provided, however, that the
      encumbrances and restrictions contained in any such Refinancing agreement
      or amendment are no less favorable to the Senior Subordinated Noteholders
      than the encumbrances and restrictions contained in such predecessor
      agreements;


                                                                              39

      encumbrance or restriction restricts the transfer of the property subject
      to such security agreements or mortgages or (C) in connection with
      purchase money obligations for property acquired in the ordinary course of
      business;

            (5) with respect to a Restricted Subsidiary, any restriction imposed
      pursuant to an agreement entered into for the sale or disposition of all
      or substantially all the Capital Stock or assets of such Restricted
      Subsidiary pending the closing of such sale or disposition;

            (6) any encumbrance or restriction of a Receivables Entity effected
      in connection with a Qualified Receivables Transaction; provided, however,
      that such restrictions apply only to such Receivables Entity; and

            (7) any encumbrance or restriction existing pursuant to other
      Indebtedness permitted to be Incurred subsequent to the Senior
      Subordinated Notes Issue Date pursuant to Section 4.03; provided, however,
      that any such encumbrance or restrictions are ordinary and customary with
      respect to the type of Indebtedness being Incurred (under the relevant
      circumstances).

            SECTION 4.06. Limitation on Sales of Assets and Subsidiary Stock.
(a) The Company shall not, and shall not permit any Restricted Subsidiary to,
make any Asset Disposition unless (i) the Company or such Restricted Subsidiary
receives consideration (including by way of relief from, or by any other Person
assuming sole responsibility for, any liabilities, contingent or otherwise) at
the time of such Asset Disposition at least equal to the fair market value (as
determined in good faith by the Company) of the shares and assets subject to
such Asset Disposition, (ii) at least 75% of the consideration thereof received
by the Company or such Restricted Subsidiary is in the form of cash or cash
equivalents (provided that the amount of (w) any liabilities (as shown on the
Company's or such Restricted Subsidiary's most recent balance sheet or in the
notes thereto) of the Company or any Restricted Subsidiary (other than
liabilities that are by their terms subordinated to the Senior Subordinated
Notes) that are assumed by the transferee of any such assets without recourse to
the Company or any of the Restricted Subsidiaries, (x) any notes or other
obligations received by the Company or such Restricted Subsidiary from such
transferee that are converted by the Company or such Restricted Subsidiary into
cash (to the extent of the cash received) within 180 days following the closing
of such Asset Disposition, (y) any Designated Noncash Consideration received by
the Company or any of its Restricted Subsidiaries in such Asset Disposition
having an aggregate fair market value, taken together with all other Designated
Noncash Consideration received pursuant to this clause (y) that is at that time
outstanding, not to exceed 5% of Adjusted Consolidated Assets at the time of the
receipt of such Designated Noncash Consideration (with the fair market value of
each item of Designated Noncash Consideration being measured at the time
received and without giving effect to subsequent changes in value) and (z) any
assets received in exchange for assets related to a Related Business of
comparable market value in the good faith determination of the Board of
Directors shall be deemed to be cash for purposes of this provision) and (iii)
an amount equal to 100% of the Net Available Cash from such Asset 


                                                                              40

Disposition is applied by the Company (or such Restricted Subsidiary, as the
case may be) (A) first, to the extent the Company elects (or is required by the
terms of any Indebtedness), to prepay, repay, redeem or purchase Senior
Indebtedness of the Company or Indebtedness (other than any Disqualified Stock
and other than any Preferred Stock) of a Wholly Owned Subsidiary (in each case
other than Indebtedness owed to the Company or an Affiliate of the Company)
within 365 days after the later of the date of such Asset Disposition or the
receipt of such Net Available Cash; (B) second, to the extent of the balance of
Net Available Cash after application in accordance with clause (A), to the
extent the Company or such Restricted Subsidiary elects, to reinvest in
Additional Assets (including by means of an Investment in Additional Assets by a
Restricted Subsidiary with Net Available Cash received by the Company or another
Restricted Subsidiary) within 365 days from the later of such Asset Disposition
or the receipt of such Net Available Cash; and (C) third, to the extent of the
balance of such Net Available Cash after application in accordance with clauses
(A) and (B), to make an Offer (as defined below) to purchase Senior Subordinated
Notes pursuant to and subject to the conditions of Section 4.06(b); provided,
however, that if the Company elects (or is required by the terms of any other
Senior Subordinated Indebtedness of the Company), such Offer may be made ratably
to purchase the Senior Subordinated Notes and other Senior Subordinated
Indebtedness of the Company; provided, however, that in connection with any
prepayment, repayment or purchase of Indebtedness pursuant to clause (A) or (C)
above, the Company or such Restricted Subsidiary shall retire such Indebtedness
and shall cause the related loan commitment (if any) to be permanently reduced
in an amount equal to the principal amount so prepaid, repaid or purchased.
Notwithstanding the foregoing provisions of this Section 4.06, the Company and
the Restricted Subsidiaries shall not be required to apply any Net Available
Cash in accordance with this Section 4.06(a) except to the extent that the
aggregate Net Available Cash from all Asset Dispositions that is not applied in
accordance with this Section 4.06 (a) exceeds $20.0 million.

            (b) In the event of an Asset Disposition that requires the purchase
of Senior Subordinated Notes (and other Senior Subordinated Indebtedness of the
Company) pursuant to Section 4.06(a)(iii)(C), the Company shall be required to
purchase Senior Subordinated Notes (and other Senior Subordinated Indebtedness
of the Company) tendered pursuant to an offer by the Company for the Senior
Subordinated Notes (and other Senior Subordinated Indebtedness of the Company)
(the "Offer") at a purchase price of 100% of their principal amount plus accrued
and unpaid interest and liquidated damages, if any, to the date of purchase in
accordance with the procedures (including prorating in the event of
oversubscription), set forth in Section 4.06(c). If the aggregate purchase price
of Senior Subordinated Notes (and other Senior Subordinated Indebtedness of the
Company) tendered pursuant to the Offer is less than the Net Available Cash
allotted to the purchase of the Senior Subordinated Notes (and other Senior
Subordinated Indebtedness of the Company), the Company may apply the remaining
Net Available Cash for any purpose permitted by the terms of this Indenture. The
Company shall not be required to make an Offer for Senior Subordinated Notes
(and other Senior Subordinated Indebtedness of the Company) pursuant to this
Section 4.06 if the Net Available Cash available therefor (after application of
the proceeds as provided in clauses (A) and (B) of Section 4.06(a)(iii)) is less
than $10.0 million for any particular Asset Disposition (which lesser amount
shall be carried forward for purposes of determining whether an Offer is
required with respect to the Net Available Cash from any subsequent Asset
Disposition).


                                                                              41

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

            (2) Not later than the date upon which written notice of an Offer is
delivered to the Senior Subordinated Notes Trustee as provided above, the
Company shall deliver to the Senior Subordinated Notes Trustee an Officers'
Certificate as to (i) the amount of the Offer (the "Offer Amount"), (ii) the
allocation of the Net Available Cash from the Asset Dispositions pursuant to
which such Offer is being made and (iii) the compliance of such allocation with
the provisions of Section 4.06(a). On such date, the Company shall also
irrevocably deposit with the Senior Subordinated Notes Trustee or with a paying
agent (or, if the Company is acting as its own paying agent, segregate and hold
in trust) an amount equal to the Offer Amount to be invested in Temporary Cash
Investments and to be held for payment in accordance with the provisions of this
Section. Upon the expiration of the period for which the Offer remains open (the
"Offer Period"), the Company shall deliver to the Senior Subordinated Notes
Trustee for cancelation the Senior Subordinated Notes or portions thereof that
have been properly tendered to and are to be accepted by the Company. The Senior
Subordinated Notes Trustee (or the Paying Agent, if not the Senior Subordinated
Notes Trustee) shall, on the date of purchase, mail or deliver payment to each
tendering Senior Subordinated Noteholder in the amount of the purchase price. In
the event that the aggregate purchase price of the Senior Subordinated Notes
(and other Senior Subordinated Indebtedness of the Company) delivered by the
Company to the Senior Subordinated Notes Trustee is less than the Offer Amount
applicable to the Senior Subordinated Notes (and other Senior Subordinated
Indebtedness of the Company), the Senior Subordinated Notes Trustee shall
deliver the excess to the Company immediately after the expiration of the Offer
Period for application in accordance with this Section 4.06.

            (3) Senior Subordinated Noteholders electing to have a Senior
Subordinated Note purchased shall be required to surrender the Senior
Subordinated Note, with an appropriate form duly completed, to the Company at
the address specified in the notice at least three Business Days prior to the
Purchase Date. Senior Subordinated Noteholders shall be entitled to withdraw
their election if the Senior Subordinated Notes Trustee or the Company receives
not later than one Business Day prior to the Purchase Date, a telegram, telex,
facsimile transmission or letter setting forth the name of the Senior
Subordinated Noteholder, the principal amount of the Senior Subordinated Note
which was delivered by the Senior Subordinated Noteholder for purchase and a
statement that such Senior Subordinated Noteholder is withdrawing his election
to have such Senior Subordinated Note purchased. If at the expiration of the
Offer Period the aggregate principal amount of Senior Subordinated Notes and any
other 


                                                                              42

Senior Subordinated Indebtedness of the Company included in the Offer
surrendered by holders thereof exceeds the Offer Amount, the Company shall
select the Senior Subordinated Notes and other Senior Subordinated Indebtedness
of the Company to be purchased on a pro rata basis (with such adjustments as may
be deemed appropriate by the Company so that only Senior Subordinated Notes and
other Senior Subordinated Indebtedness of the Company in denominations of
$1,000, or integral multiples thereof, shall be purchased). Senior Subordinated
Noteholders whose Senior Subordinated Notes are purchased only in part will be
issued new Senior Subordinated Notes equal in princi pal amount to the
unpurchased portion of the Senior Subordinated Notes surrendered.

            (4) At the time the Company delivers Senior Subordinated Notes to
the Senior Subordinated Notes Trustee which are to be accepted for purchase, the
Company shall also deliver an Officers' Certificate stating that such Senior
Subordinated Notes are to be accepted by the Company pursuant to and in
accordance with the terms of this Sec tion. A Senior Subordinated Note shall be
deemed to have been accepted for purchase at the time the Senior Subordinated
Notes Trustee, directly or through an agent, mails or delivers payment therefor
to the surrendering Senior Subordinated Noteholder.

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

            SECTION 4.07. Limitation on Transactions with Affiliates. (a) The
Company shall not, and shall not cause or 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 of the foregoing, an "Affiliate Transaction") involving
aggregate consideration in excess of $5.0 million, unless (i) such Affiliate
Transaction is on terms that are not materially less favorable to the Company or
the relevant Restricted Subsidiary than those that would have been obtained in a
comparable transaction by the Company or such Restricted Subsidiary with an
unrelated Person and (ii) with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving aggregate consideration in excess of
$10.0 million, the Company delivers to the Senior Subordinated Notes Trustee a
resolution adopted by the majority of the Board of Directors, approving such
Affiliate Transaction and set forth in an Officers' Certificate certifying that
such Affiliate Transaction complies with clause (i) above.

            (b) The provisions of Section 4.07(a) shall not prohibit (i) any
Restricted Payment permitted to be paid pursuant to Section 4.04, (ii) any
issuance of securities, or other payments, Guarantees, awards or grants in cash,
securities or otherwise pursuant to, or the funding of, employment arrangements,
stock options and stock ownership plans approved by the Board of Directors,
(iii) the grant of stock options or similar rights to employees and directors of
the Company pursuant to plans approved by the Board of Directors, (iv) loans or
advances to employees in the ordinary course of business in accordance with past
practices of the Company, but in any event not to exceed $5.0 million in the
aggregate outstanding at any one time, (v) the payment of reasonable fees 


                                                                              43

to directors of the Company and its Restricted Subsidiaries who are not
employees of the Company or its Subsidiaries, (vi) any transaction between the
Company and a Restricted Subsidiary or between Restricted Subsidiaries, (vii)
any transaction effected as part of a Qualified Receivables Transaction, (viii)
any payment by the Company to Holdings to permit Holdings to pay any Federal,
state, local or other taxes that are then actually due and owing by Holdings,
(ix) indemnification agreements with, and the payment of fees and indemnities
to, directors, officers and employees of the Company and its Restricted
Subsidiaries, in each case, in the ordinary course of business, (x) any
employment, compensation, noncompetition or confidentiality agreement entered
into by the Company and its Restricted Subsidiaries with its employees in the
ordinary course of business, (xi) the payment by the Company of fees, expenses
and other amounts to Cypress and its Affiliates in connection with the
Recapitalization, (xii) payments by the Company or any of its Restricted
Subsidiaries to Cypress and its Affiliates made pursuant to any financial
advisory, financing, underwriting or placement agreement, or in respect of other
investment banking activities, in each case, as determined by the Board of
Directors in good faith, (xiii) any issuance of Capital Stock of the Company
(other than Disqualified Stock), (xiv) any agreement as in effect as of the date
of this Indenture or any amendment or replacement hereto so long as any such
amendment or replacement agreement is not more disadvantageous to the Senior
Subordinated Noteholders of the Senior Subordinated Notes in any material
respect than the original agreement as in effect on the Closing Date and (xv)
transactions in which the Company or any of its Restricted Subsidiaries, as the
case may be, delivers to the Senior Subordinated Notes Trustee a letter from an
Independent Financial Advisor stating that such transaction is fair to the
Company or such Restricted Subsidiary from a financial point of view or meets
the requirements of Section 4.07(a).

            SECTION 4.08. Change of Control. (a) Upon the occurrence of a Change
of Control, unless all Senior Subordinated Notes have been called for redemption
pursuant to paragraph 5 of the Senior Subordinated Notes, each Senior
Subordinated Noteholder shall have the right to require the Company to
repurchase all or any part of such Senior Subordinated Noteholder's Senior
Subordinated Notes at a purchase price in cash equal to 101% of the principal
amount thereof plus accrued and unpaid interest and liquidated damages, if any,
to the date of repurchase (subject to the right of Senior Subordinated
Noteholders of record on the relevant record date to receive interest due on the
relevant interest payment date), in accordance with Section 4.08(b). Prior to
the mailing of the notice referred to below, but in any event within 30 days
following the date on which the Company becomes aware that a Change of Control
has occurred, if the purchase of the Senior Subordinated Notes would violate or
constitute a default under any other Indebtedness of the Company, then the
Company shall, to the extent needed to permit such purchase of Senior
Subordinated Notes, either (i) repay all such Indebtedness and terminate all
commitments outstanding thereunder or (ii) request the holders of such
Indebtedness to give the requisite consents to permit the purchase of the Senior
Subordinated Notes as provided below. Until such time as the Company is able to
repay all such Indebtedness and terminate all commitments outstanding thereunder
or such time as such requisite consents are obtained, the Company shall not be
required to make the Change of Control Offer or purchase the Senior Subordinated
Notes pursuant to the provisions described below.

            (b) Within 30 days following any Change of Control, unless all
Senior Subordinated Notes have been called for redemption pursuant to paragraph
5 of the Senior Subordinated Notes, the Company shall mail a notice to each
Senior Subordinated 


                                                                              44

Noteholder with a copy to the Senior Subordinated Notes Trustee (the "Change of
Control Offer") stating:

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

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

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

            (4) the instructions determined by the Company, consistent with this
      Section, that a Senior Subordinated Noteholder must follow in order to
      have its Senior Subordinated Notes repurchased.

            (c) Senior Subordinated Noteholders electing to have a Senior
Subordinated Note repurchased shall be required to surrender the Senior
Subordinated Note, with an appropriate form duly completed, to the Company at
the address specified in the notice at least three Business Days prior to the
repurchase date. Senior Subordinated Noteholders shall be entitled to withdraw
their election if the Senior Subordinated Notes Trustee or the Company receives
not later than one Business Day prior to the repurchase date a telegram, telex,
facsimile transmission or letter setting forth the name of the Senior
Subordinated Noteholder, the principal amount of the Senior Subordinated Note

            (d) On the repurchase date, all Senior Subordinated Notes
repurchased by the Company under this Section shall be delivered to the Senior
Subordinated Notes Trustee for cancelation, and the Company shall pay the
purchase price plus accrued and unpaid interest and liquidated damages, if any,

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

            (f) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Senior Subordinated Notes

laws or regulations 


                                                                              45

conflict with provisions of this Section, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section by virtue thereof.

            SECTION 4.09. Compliance Certificate. The Company shall deliver to
the Senior Subordinated Notes Trustee within 120 days after the end of each
fiscal year of the Company an Officers' Certificate stating that a review of the
Company's activities during the preceding fiscal year has been made under the
supervision of the signing Officers with a view to determining whether the
Company has kept, observed, performed and fulfilled its obligations under this
Indenture and further stating, as to each such Officer signing such certificate,
whether to the best of such Officer's knowledge the Company during such
preceding fiscal year has kept, observed, performed and fulfilled each and every
such covenant contained in this Indenture and that in the course of the
performance by the signers of their duties as Officers of the Company they would
normally have knowledge of any Default and whether or not the signers know of
any Default that occurred during such period. If they do know of any Default,
the certificate shall describe the Default, its status and what action the
Company is taking or proposes to take with respect thereto. The Company also
shall comply with Section 314(a)(4) of the TIA.

            SECTION 4.10. Further Instruments and Acts. Upon request of the
Senior Subordinated Notes Trustee, the Company shall execute and deliver such
further instruments and do such further acts as may be reasonably necessary or
proper to carry out more effectively the purpose of this Indenture.

            SECTION 4.11. Limitation on the Sale or Issuance of Capital Stock of
Restricted Subsidiaries. The Company shall not sell or otherwise dispose of any
shares of Capital Stock of a Restricted Subsidiary, and shall not permit any
Restricted Subsidiary, directly or indirectly, to issue or sell or otherwise
dispose of any shares of its Capital Stock except: (i) to the Company or a
Wholly Owned Subsidiary or to any director of a Restricted Subsidiary to the
extent required as director's qualifying shares; (ii) if, immediately after
giving effect to such issuance, sale or other disposition, neither the Company
nor any of its Subsidiaries own any Capital Stock of such Restricted Subsidiary
or (iii) if, immediately after giving effect to such issuance or sale, such
Restricted Subsidiary would no longer constitute a Restricted Subsidiary and any
Investment in such Person remaining after giving effect thereto would have been
permitted to be made under Section 4.04 if made on the date of such issuance,
sale or other disposition. The provisions of this Section 4.11 shall not
prohibit any transaction effected as part of a Qualified Receivables
Transaction. The proceeds of any sale of such Capital Stock permitted hereby
shall be treated as Net Available Cash from an Asset Disposition and shall be
applied in accordance with Section 4.06.

            SECTION 4.12. Limitation on Liens. The Company shall not, and shall
not permit any Restricted Subsidiary to, directly or indirectly, Incur or permit
to exist any Lien of any nature whatsoever that secures Senior Subordinated
Indebtedness of the Company or Subordinated Obligations of the Company on any of
its property or assets (including Capital Stock of a Restricted Subsidiary),
whether owned at the Closing Date or thereafter acquired, other than Permitted
Liens, without effectively providing that the Senior Subordinated Notes shall be
secured equally and ratably with (or on a senior basis to in the case of
Subordinated Obligations of the Company) the obligations so secured for so long
as such obligations are so secured.


                                                                              46

                                Successor Company

            SECTION 5.01. When Company May Merge or Transfer Assets. The Company
shall not consolidate with or merge with or into, or convey, transfer or lease
all or substantially all its assets to, any Person, unless:

            (i) the resulting, surviving or transferee Person (the "Successor
      Company") shall be a corporation organized and existing under the laws of
      the United States of America, any State thereof or the District of
      Columbia and the Successor Company (if not the Company) shall expressly
      assume, by an indenture supplemental hereto, executed and delivered to the
      Senior Subordinated Notes Trustee, in form satisfactory to the Senior
      Subordinated Notes Trustee, all the obligations of the Company under the
      Senior Subordinated Notes and this Indenture;

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

            (iii) immediately after giving effect to such transaction, (A) the
      Successor Company would be able to Incur an additional $1.00 of
      Indebtedness pursuant to Section 4.03(a) or (B) the Consolidated Coverage
      Ratio for the Successor Company and its Restricted Subsidiaries would be
      greater than such ratio for the Company and its Restricted Subsidiaries
      immediately prior to such transaction;

            (iv) immediately after giving effect to such transaction, the
      Successor Company shall have Consolidated Net Worth in an amount which is
      not less than the Consolidated Net Worth of the Company immediately prior
      to such transaction; and

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

            The Successor Company shall succeed to, and be substituted for, and
may exercise every right and power of, the Company under this Indenture, but the
predecessor Company in the case of a conveyance, transfer or lease of all or
substantially all its assets shall not be released from the obligation to pay
the principal of and interest on the Senior Subordinated Notes.

            Notwithstanding clause (iii) above, a Wholly Owned Subsidiary may be
consolidated with or merged into the Company and the Company may consolidate
with or merge with or into (A) another Person, if such Person is a single
purpose corporation that has not conducted any business or Incurred any
Indebtedness or other liabilities and such transaction is being consummated
solely to change the state of incorporation of the


                                                                              47

                              Defaults and Remedies

            SECTION 6.01. Events of Default. An "Event of Default" occurs if:

            (1) the Company defaults in any payment of interest on any Senior
      Subordinated Note when the same becomes due and payable, whether or not
      such payment shall be prohibited by Article 10, and such default continues
      for a period of 30 days;

            (2) the Company (i) defaults in the payment of the principal of any
      Senior Subordinated Note when the same becomes due and payable at its
      Stated Maturity, upon redemption, upon declaration or otherwise, whether
      or not such payment shall be prohibited by Article 10 or (ii) fails to
      redeem or purchase Senior Subordinated Notes when required pursuant to
      this Indenture or the Senior Subordinated Notes, whether or not such
      redemption or purchase shall be prohibited by Article 10;

            (3) the Company fails to comply with Section 5.01;

            (4) the Company fails to comply with Section 4.02, 4.03, 4.04, 4.05,
      4.06, 4.07, 4.08, 4.11 or 4.12 (other than a failure to purchase Senior
      Subordinated Notes when required under Section 4.06 or 4.08) and such
      failure continues for 30 days after the notice specified below;

            (5) the Company fails to comply with any of its agreements in the
      Senior Subordinated Notes or this Indenture (other than those referred to
      in (1), (2), (3) or (4) above) and such failure continues for 60 days
      after the notice specified below;

            (6) Indebtedness of the Company or any Significant Subsidiary is not
      paid within any applicable grace period after final maturity or the
      acceleration of any such Indebtedness by the holders thereof because of a
      default and the total amount of such Indebtedness unpaid or accelerated
      exceeds $25 million or its foreign currency equivalent at the time and
      such failure continues for 10 days after the notice specified below;


                                                                              48

            (7) the Company or any Significant Subsidiary pursuant to or within
      the meaning of any Bankruptcy Law:

                  (A) commences a voluntary case;

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

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

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

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

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

                  (A) is for relief against the Company or any Significant
            Subsidiary in an involuntary case;

                  (B) appoints a Custodian of the Company or any Significant
            Subsidiary or for any substantial part of its property; or

                  (C) orders the winding up or liquidation of the Company or any
            Significant Subsidiary;

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

            (9) any judgment or decree for the payment of money in excess of $25
      million or its foreign currency equivalent at the time is entered against
      the Company or any Significant Subsidiary and is not discharged, waived or
      stayed and either (A) an enforcement proceeding has been commenced by any
      creditor upon such judgment or decree or (B) there is a period of 60 days
      following the entry of such judgment or decree during which such judgment
      or decree is not discharged, waived or the execution thereof stayed and
      such judgment or decree is not discharged, waived or the execution thereof
      stayed within 10 days after the notice specified below.

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

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


                                                                              49

            A Default under clause (4), (5), (6) or (9) above is not an Event of
Default until the Senior Subordinated Notes Trustee or the Senior Subordinated
Noteholders of at least 25% in principal amount of the outstanding Senior
Subordinated Notes notify the Company of the Default and the Company does not
cure such Default within the time specified after receipt of such notice. Such
notice must specify the Default, demand that it be remedied and state that such
notice is a "Notice of Default".

            The Company shall deliver to the Senior Subordinated Notes Trustee,
within 30 days after the occurrence thereof, written notice in the form of an
Officers' Certificate of any event which with the giving of notice or the lapse
of time would become an Event of Default under clause (4), (5) or (9), its
status and what action the Company is taking or proposes to take with respect
thereto.

            SECTION 6.02. Acceleration. If an Event of Default (other than an
Event of Default specified in Section 6.01(7) or (8) with respect to the
Company) occurs and is continuing, the Senior Subordinated Notes Trustee by
notice to the Company, or the Senior Subordinated Noteholders of at least 25% in
principal amount of the outstanding Senior Subordinated Notes by notice to the
Company, may declare the principal of and accrued but unpaid interest on all the
Senior Subordinated Notes to be due and payable. Upon such a declaration, such
principal and interest shall be due and payable immediately. If an Event of
Default specified in Section 6.01(7) or (8) with respect to the Company occurs,
the principal of and interest on all the Senior Subordinated Notes shall ipso
facto become and be immediately due and payable without any declaration or other
act on the part of the Senior Subordinated Notes Trustee or any Senior
Subordinated Noteholders. The Senior Subordinated Noteholders of a majority in
principal amount of the Senior Subordinated Notes by notice to the Senior
Subordinated Notes Trustee may rescind an acceleration and its consequences if
the rescission would not conflict with any judgment or decree and if all
existing Events of Default have been cured or waived except nonpayment of
principal or interest that has become due solely because of acceleration. No
such rescission shall affect any subsequent Default or impair any right
consequent thereto.

            SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Senior Subordinated Notes Trustee may pursue any available
remedy to collect the payment of principal of or interest on the Senior
Subordinated Notes or to enforce the performance of any provision of the Senior
Subordinated Notes or this Indenture.

            The Senior Subordinated Notes Trustee may maintain a proceeding even
if it does not possess any of the Senior Subordinated Notes or does not produce
any of them in the proceeding. A delay or omission by the Senior Subordinated
Notes Trustee or any Senior Subordinated Noteholder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

            SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in
principal amount of the Senior Subordinated Notes by notice to the Senior
Subordinated Notes Trustee may waive an existing Default and its consequences
except (i) a Default in the payment of the principal of or interest on a Senior
Subordinated Note, (ii) a Default arising from the failure to redeem or purchase
any Senior Subordinated Note when 


                                                                              50

required pursuant to the terms of this Indenture or (iii) a Default in respect
of a provision that under Section 9.02 cannot be amended without the consent of
each Senior Subordinated Noteholder affected. When a Default is waived, it is
deemed cured, but no such waiver shall extend to any subsequent or other Default
or impair any consequent right.

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

            SECTION 6.06. Limitation on Suits. Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no Senior
Subordinated Noteholder may pursue any remedy with respect to this Indenture or
the Senior Subordinated Notes unless:

            (1) the Senior Subordinated Noteholder gives to the Senior
      Subordinated Notes Trustee written notice stating that an Event of Default
      is continuing;

            (2) the Senior Subordinated Noteholders of at least 25% in principal
      amount of the Senior Subordinated Notes make a written request to the
      Senior Subordinated Notes Trustee to pursue the remedy;

            (3) such Senior Subordinated Noteholder or Senior Subordinated
      Noteholders offer to the Senior Subordinated Notes Trustee reasonable
      security or indemnity against any loss, liability or expense;

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

            (5) the Senior Subordinated Noteholders of a majority in principal
      amount of the Senior Subordinated Notes do not give the Senior
      Subordinated Notes Trustee a direction inconsistent with the request
      during such 60-day period.

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

            SECTION 6.07. Rights of Senior Subordinated Noteholders to Receive
Payment. Notwithstanding any other provision of this Indenture, the right of any
Senior 


                                                                              51

Subordinated Noteholder to receive payment of principal of and liquidated
damages and interest on the Senior Subordinated Notes held by such Senior
Subordinated Noteholder, on or after the respective due dates expressed in the
Senior Subordinated Notes, or to bring suit for the enforcement of any such
payment on or after such respective dates, shall not be impaired or affected
without the consent of such Senior Subordinated Noteholder.

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

            SECTION 6.09. Senior Subordinated Notes Trustee May File Proofs of
Claim. The Senior Subordinated Notes Trustee may file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the
claims of the Senior Subordinated Notes Trustee and the Senior Subordinated
Noteholders allowed in any judicial proceedings relative to the Company,
Holdings, their creditors or their property and, unless prohibited by law or
applicable regulations, may vote on behalf of the Senior Subordinated
Noteholders in any election of a trustee in bankruptcy or other Person
performing similar functions, and any Custodian in any such judicial proceeding
is hereby authorized by each Senior Subordinated Noteholder to make payments to
the Senior Subordinated Notes Trustee and, in the event that the Senior
Subordinated Notes Trustee shall consent to the making of such payments directly
to the Senior Subordinated Noteholders, to pay to the Senior Subordinated Notes
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Senior Subordinated Notes Trustee, its agents
and its counsel, and any other amounts due the Senior Subordinated Notes Trustee
under Section 7.07.

            SECTION 6.10. Priorities. If the Senior Subordinated Notes Trustee
col lects any money or property pursuant to this Article 6, it shall pay out the
money or property in the following order:

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

            SECOND: to holders of Senior Indebtedness of the Company to the
      extent required by Article 10;

            THIRD: to Senior Subordinated Noteholders for amounts due and unpaid
      on the Senior Subordinated Notes for principal and interest, ratably, and
      any liquidated damages without preference or priority of any kind,
      according to the amounts due and payable on the Senior Subordinated Notes
      for principal, any liquidated damages and interest, respectively; and

            FOURTH: to the Company.

            The Senior Subordinated Notes Trustee may fix a record date and
payment date for any payment to Senior Subordinated Noteholders pursuant to this
Section. At least 15 days before such record date, the Senior Subordinated Notes
Trustee 


                                                                              52

shall mail to each Senior Subordinated Noteholder and the Company a notice that
states the record date, the payment date and amount to be paid.

            SECTION 6.11. Undertaking for Costs. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Senior
Subordinated Notes Trustee for any action taken or omitted by it as Senior
Subordinated Notes 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 Senior Subordinated Notes
Trustee, a suit by a Senior Subordinated Noteholder pursuant to Section 6.07 or
a suit by Senior Subordinated Noteholders of more than 10% in principal amount
of the Senior Subordinated Notes.

            SECTION 6.12. Waiver of Stay or Extension Laws. Neither the Company
nor Holdings (to the extent it may lawfully do so) shall at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or
advantage of, any stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this
Indenture; and the Company and Holdings (to the extent that it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law, and shall
not hinder, delay or impede the execution of any power herein granted to the
Senior Subordinated Notes Trustee, but shall suffer and permit the execution of
every such power as though no such law had been enacted.

                                    ARTICLE 7

                        Senior Subordinated Notes Trustee

            SECTION 7.01. Duties of Senior Subordinated Notes Trustee. (a) If an
Event of Default has occurred and is continuing, the Senior Subordinated Notes
Trustee shall exercise the rights and powers vested in it by this Indenture and
use the same degree of care and skill in their exercise as a prudent Person
would exercise or use under the circumstances in the conduct of such Person's
own affairs.

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

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

            (2) in the absence of bad faith on its part, the Senior Subordinated
      Notes 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 Senior Subordinated Notes Trustee and conforming
      to the requirements of this Indenture. However, the Senior Subordinated
      Notes Trustee shall examine the certificates and opinions to determine
      whether or not they conform to the requirements of this Indenture.


                                                                              53

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

affecting the liability of or affording protection to the Senior Subordinated

mail to each Senior Subordinated Noteholder notice of the Default within the
earlier of 90 days after it occurs or 30 days after it is known to a Trust

                                                                              55

principal, premium (if any) or interest on any Senior Subordinated Note
(including payments pursuant to the redemption provisions of such Senior
Subordinated Note), the Senior Subordinated Notes Trustee may withhold notice if

            SECTION 7.06. Reports by Senior Subordinated Notes Trustee to Senior
Subordinated Noteholders. As promptly as practicable after each June 30
beginning with the June 30 following the first anniversary of the date of this
Indenture, and in any event prior to August 31 in each subsequent year, the
Senior Subordinated Notes Trustee shall, to the extent that any of the events
described in TIA ss. 313(a) occurred within the previous twelve months, but not
otherwise, mail to each Senior Subordinated Noteholder a brief report dated as
of June 30 that complies with Section 313(a) of the TIA. The Senior Subordinated
Notes Trustee shall also comply with Section 313(b) of the TIA.

            A copy of each report at the time of its mailing to Senior
Subordinated Noteholders shall be filed with the SEC and each stock exchange (if
any) on which the Senior Subordinated Notes are listed. The Company agrees to
notify promptly the Senior Subordinated Notes Trustee whenever the Senior
Subordinated Notes become listed on any stock exchange and of any delisting
thereof.

            SECTION 7.07. Compensation and Indemnity. The Company shall pay to
the Senior Subordinated Notes Trustee from time to time such compensation as the
Company and the Senior Subordinated Notes Trustee shall from time to time agree
in writing. The Senior Subordinated Notes Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company
shall reimburse the Senior Subordinated Notes Trustee upon request for all
reasonable out-of-pocket expenses incurred or made by it, including costs of
collection, in addition to the compensation for its services. Such expenses
shall include the reasonable compensation and expenses, disbursements and
advances of the Senior Subordinated Notes Trustee's agents, counsel, accountants
and experts. The Company and Holdings, jointly and severally shall indemnify the
Senior Subordinated Notes Trustee, and hold it harmless, against any and all
loss, liability or expense (including reasonable attorneys' fees) incurred by or
in connection with the offer and sale of the Senior Subordinated Notes or the
administration of this trust and the performance of its duties hereunder. The
Senior Subordinated Notes Trustee shall notify the Company of any claim for
which it may seek indemnity promptly upon obtaining actual knowledge thereof;
provided, however, that any failure so to notify the Company shall not relieve
the Company or Holdings of its indemnity obligations hereunder. The Company
shall defend the claim and the indemnified party shall provide reasonable
cooperation at the Company's expense in the defense. Such indemnified parties
may have separate counsel and the Company and Holdings, as applicable, shall pay
the fees and expenses of such counsel; provided, however, that the Company shall
not be required to pay such fees and expenses if it assumes such indemnified
parties' defense and, in such indemnified parties' reasonable judgment, there is
no conflict of interest between the Company and Holdings, as applicable, and
such parties in connection with such defense. The Company need not reimburse any
expense or indemnify against any loss, liability or expense incurred by an
indemnified party through such party's own wilful misconduct and negligence.

            To secure the Company's payment obligations in this Section, the
Senior Subordinated Notes Trustee shall have a lien prior to the Senior
Subordinated Notes on 


                                                                              56

all money or property held or collected by the Senior Subordinated Notes Trustee
other than money or property held in trust to pay principal of and interest and
any liquidated damages on particular Senior Subordinated Notes.

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

            SECTION 7.08. Replacement of Senior Subordinated Notes Trustee. The
Senior Subordinated Notes Trustee may resign at any time by so notifying the
Company. The Holders of a majority in principal amount of the Senior
Subordinated Notes may remove the Senior Subordinated Notes Trustee by so
notifying the Senior Subordinated Notes Trustee and may appoint a successor
Senior Subordinated Notes Trustee. The Company shall remove the Senior
Subordinated Notes Trustee if:

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

            (2) the Senior Subordinated Notes Trustee is adjudged bankrupt or
      insol vent;

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

            (4) the Senior Subordinated Notes Trustee otherwise becomes
      incapable of acting.

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

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


                                                                              57

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

            If the Senior Subordinated Notes Trustee fails to comply with
Section 7.10, any Senior Subordinated Noteholder may petition any court of
competent jurisdiction for the removal of the Senior Subordinated Notes Trustee
and the appoint ment of a successor Senior Subordinated Notes Trustee.

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

            SECTION 7.09. Successor Senior Subordinated Notes Trustee by Merger.
If the Senior Subordinated Notes Trustee consolidates with, merges or converts
into, or transfers all or substantially all its corporate trust business or
assets to, another corporation or banking association, the resulting, surviving
or transferee corporation without any further act shall be the successor Senior
Subordinated Notes Trustee.

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

            SECTION 7.10. Eligibility; Disqualification. The Senior Subordinated
Notes Trustee shall at all times satisfy the requirements of TIA ss. 310(a). The
Senior Subordinated Notes Trustee shall have a combined capital and surplus of
at least $100,000,000 as set forth in its most recent published annual report of
condition. The Senior Subordinated Notes Trustee shall comply with TIA ss.
310(b); provided, however, that there shall be excluded from the operation of
TIA ss. 310(b)(1) any indenture or indentures under which other securities or
certificates of interest or participation in other securities of the Company are
outstanding if the requirements for such exclusion set forth in TIA ss.
310(b)(1) are met.

            SECTION 7.11. Preferential Collection of Claims Against Company. The
Senior Subordinated Notes Trustee shall comply with TIA ss. 311(a), excluding
any creditor relationship listed in TIA ss. 311(b). A Senior Subordinated Notes
Trustee who has resigned or been removed shall be subject to TIA ss. 311(a) to
the extent indicated.


                                                                              58

                                    ARTICLE 8

                       Discharge of Indenture; Defeasance

            SECTION 8.01. Discharge of Liability on Senior Subordinated Notes;
Defeasance. (a) When (i) the Company delivers to the Senior Subordinated Notes
Trustee all outstanding Senior Subordinated Notes (other than Senior
Subordinated Notes replaced pursuant to Section 2.08) for cancelation or (ii)
all outstanding Senior Subordinated Notes have become due and payable, whether
at maturity or as a result of the mailing of a notice of redemption pursuant to
Article 3 hereof, and the Company irrevocably deposits with the Senior
Subordinated Notes Trustee funds or U.S. Government Obligations on which payment
of principal and interest when due will be sufficient to pay at maturity or upon
redemption all outstanding Senior Subordinated Notes, including interest thereon
to maturity or such redemption date (other than Senior Subordinated Notes
replaced pursuant to Section 2.08), and if in either case the Company pays all
other sums payable hereunder by the Company, then this Indenture shall, subject
to Section 8.01(c), cease to be of further effect. The Senior Subordinated Notes
Trustee shall acknowledge satisfaction and discharge of this Indenture on demand
of the Company accompanied by an Officers' Certificate and an Opinion of Counsel
and at the cost and expense of the Company.

            (b) Subject to Sections 8.01(c) and 8.02, the Company at any time
may terminate (i) all of its obligations under the Senior Subordinated Notes and
this Indenture ("legal defeasance option") or (ii) its obligations under
Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11 and 4.12 and
the operation of Section 5.01(iii), 5.01(iv), 6.01(4), 6.01(6), 6.01(7) (with
respect to Significant Subsidiaries of the Company only), 6.01(8) (with respect
to Significant Subsidiaries of the Company only) and 6.01(9) ("covenant
defeasance option"). The Company may exercise its legal defeasance option
notwithstanding its prior exercise of its covenant defeasance option. In the
event that the Company terminates all of its obligations under the Senior
Subordinated Notes and this Indenture by exercising its legal defeasance option,
the obligations under the Holdings Guarantee shall be terminated simultaneously
with the termination of such obligations.

            If the Company exercises its legal defeasance option, payment of the
Senior Subordinated Notes may not be accelerated because of an Event of Default.
If the Company exercises its covenant defeasance option, payment of the Senior
Subordinated Notes may not be accelerated because of an Event of Default
specified in Section 6.01(4), 6.01(6), 6.01(7) (with respect to Significant
Subsidiaries of the Company only) or 6.01(8) (with respect to Significant
Subsidiaries of the Company only) or because of the failure of the Company to
comply with clauses (iii) and (iv) of Section 5.01.

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

            (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 7.07, 7.08 and in
this Article 8 shall survive until the Senior Subordinated Notes have been paid
in full. Thereafter, the Company's obligations in Sections 7.07, 8.04 and 8.05
shall survive.


                                                                              59

            SECTION 8.02. Conditions to Defeasance. The Company may exercise its
legal defeasance option or its covenant defeasance option only if:

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

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

            (3) 123 days pass after the deposit is made and during the 123-day
      period no Default specified in Section 6.01(7) or (8) with respect to the
      Company occurs which is continuing at the end of the period;

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

            (5) the Company delivers to the Senior Subordinated Notes Trustee an
      Opinion of Counsel to the effect that the trust resulting from the deposit
      does not constitute, or is qualified as, a regulated investment company
      under the Investment Company Act of 1940;

            (6) in the case of the legal defeasance option, the Company shall
      have delivered to the Senior Subordinated Notes Trustee an Opinion of
      Counsel stating that (i) the Company has received from, or there has been
      published by, the Internal Revenue Service a ruling, or (ii) since the
      date of this Indenture there has been a change in the applicable Federal
      income tax law, in either case to the effect that, and based thereon such
      Opinion of Counsel shall confirm that, the Senior Subordinated Noteholders
      will not recognize income, gain or loss for Federal income tax purposes as
      a result of such deposit and 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 deposit and defeasance had not
      occurred;

            (7) in the case of the covenant defeasance option, the Company shall
      have delivered to the Senior Subordinated Notes Trustee an Opinion of
      Counsel to the effect that the Senior Subordinated Noteholders will not
      recognize income, gain or loss for Federal income tax purposes as a result
      of such deposit and 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 deposit and defeasance had not occurred; and

            (8) the Company delivers to the Senior Subordinated Notes Trustee an
      Officers' Certificate and an Opinion of Counsel, each stating that all
      conditions 


                                                                              60

      precedent to the defeasance and discharge of the Senior Subordinated Notes
      as contemplated by this Article 8 have been complied with.

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

            SECTION 8.03. Application of Trust Money. The Senior Subordinated
Notes Trustee shall hold in trust money or U.S. Government Obligations deposited
with it pursuant to this Article 8. It shall apply the deposited money and the
money from U.S. Government Obligations through the Paying Agent and in

the Senior Subordinated Notes. Money and securities so held in trust are not
subject to Article 10.

            SECTION 8.04. Repayment to Company. The Senior Subordinated Notes

            Subject to any applicable abandoned property law, the Senior

written request any money held by them for the payment of principal or interest
that remains unclaimed for two years, and, thereafter, Senior Subordinated
Noteholders entitled to the money must look to the Company for payment as
general creditors.

            SECTION 8.05. Indemnity for Government Obligations. The Company
shall pay and shall indemnify the Senior Subordinated Notes Trustee against any
tax, fee or other charge imposed on or assessed against deposited U.S.
Government Obligations or the principal and interest received on such U.S.
Government Obligations.

            SECTION 8.06. Reinstatement. If the Senior Subordinated Notes
Trustee or Paying Agent is unable to apply any money or U.S. Government
Obligations in accordance with this Article 8 by reason of any legal proceeding
or by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company's
obligations under this Indenture and the Senior Subordinated Notes shall be
revived and reinstated as though no deposit had occurred pursuant to this
Article 8 until such time as the Senior Subordinated Notes Trustee or Paying
Agent is permitted to apply all such money or U.S. Government Obligations in
accordance with this Article 8; provided, however, that, if the Company has made
any payment of interest on or principal of any Senior Subordinated Notes because
of the reinstatement of its obligations, the Company shall be subrogated to the
rights of the Senior Subordinated Noteholders of such Senior Subordinated Notes
to receive such payment from the money or U.S. Government Obligations held by
the Senior Subordinated Notes Trustee or Paying Agent.

      any Senior Subordinated Noteholder; or

            (9) to provide for the issuance of the Senior Subordinated Exchange
      Notes, Private Senior Subordinated Exchange Notes or Additional Senior
      Subordinated Notes, which shall have terms substantially identical in all
      material respects to the Original Senior Subordinated Notes (except that
      the transfer restrictions contained in the Original Senior Subordinated
      Notes shall be modified or eliminated, as appropriate), and which shall be
      treated, together with any outstanding Original Senior Subordinated Notes,
      as a single issue of securities.

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

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

            SECTION 9.02. With Consent of Senior Subordinated Noteholders. The
Company, Holdings and the Senior Subordinated Notes Trustee may amend this


                                                                              62

Indenture or the Senior Subordinated Notes with the written consent of the
Holders of at least a majority in principal amount of the Senior Subordinated
Notes then outstanding (including consents obtained in connection with a tender
offer or exchange offer for the Senior Subordinated Notes), without notice to
any other Senior Subordinated Noteholder. However, without the consent of each
Holder of an outstanding Senior Subordinated Note affected, an amendment may
not:

            (1) reduce the principal amount of Senior Subordinated Notes whose
      Senior Subordinated Noteholders must consent to an amendment;

            (2) reduce the rate of or extend the time for payment of interest or
      any liquidated damages on any Senior Subordinated Note;

            (3) reduce the principal of or extend the Stated Maturity of any
      Senior Subordinated Note;

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

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

            (6) make any change in Article 10 or Article 12 that adversely
      affects the rights of any Senior Subordinated Noteholder under Article 10
      or Article 12; or

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

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

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

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

            SECTION 9.03. Compliance with Trust Indenture Act. Every amendment
to this Indenture or the Senior Subordinated Notes shall comply with the TIA as
then in effect.

            SECTION 9.04. Revocation and Effect of Consents and Waivers. A
consent to an amendment or a waiver by a Senior Subordinated Noteholder of a
Senior Subordinated Note shall bind the Senior Subordinated Noteholder and every
subsequent 


                                                                              63

Senior Subordinated Noteholder of that Senior Subordinated Note or portion of
the Senior Subordinated Note that evidences the same debt as the consenting
Senior Subordinated Noteholder's Senior Subordinated Note, even if notation of
the consent or waiver is not made on the Senior Subordinated Note. However, any
such Senior Subordinated Noteholder or subsequent Senior Subordinated Noteholder
may revoke the consent or waiver as to such Senior Subordinated Noteholder's
Senior Subordinated Note or portion of the Senior Subordinated Note if the
Senior Subordinated Notes Trustee receives the notice of revocation before the
date the amendment or waiver becomes effective. After an amendment or waiver
becomes effective, it shall bind every Senior Subordinated Noteholder. An
amendment or waiver becomes effective once both (i) the requisite number of
consents have been received by the Company or the Senior Subordinated Notes
Trustee and (ii) such amendment or waiver has been executed by the Company and
the Senior Subordinated Notes Trustee.

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

            SECTION 9.05. Notation on or Exchange of Senior Subordinated Notes.
If an amendment changes the terms of a Senior Subordinated Note, the Senior
Subordinated Notes Trustee may require the Senior Subordinated Noteholder of the
Senior Subordinated Note to deliver it to the Senior Subordinated Notes Trustee.
The Senior Subordinated Notes Trustee may place an appropriate notation on the
Senior Subordinated Note regarding the changed terms and return it to the Senior
Subordinated Noteholder. Alternatively, if the Company or the Senior
Subordinated Notes Trustee so determines, the Company in exchange for the Senior
Subordinated Note shall issue and the Senior Subordinated Notes Trustee shall
authenticate a new Senior Subordinated Note that reflects the changed terms.
Failure to make the appropriate notation or to issue a new Senior Subordinated
Note shall not affect the validity of such amendment.

            SECTION 9.06. Senior Subordinated Notes Trustee To Sign Amendments.
The Senior Subordinated Notes Trustee shall sign any amendment authorized
pursuant to this Article 9 if the amendment does not adversely affect the
rights, duties, liabilities or immunities of the Senior Subordinated Notes
Trustee. If it does, the Senior Subordinated Notes Trustee may but need not sign
it. In signing such amendment the Senior Subordinated Notes Trustee shall be
entitled to receive indemnity reasonably satisfactory to it and to receive, and
(subject to Section 7.01) shall be fully protected in relying upon, an Officers'
Certificate and an Opinion of Counsel stating that such amendment is authorized
or permitted by this Indenture and that such amendment is the legal, valid and
binding obligation of the Company and Holdings enforceable against them in
accordance with its terms, subject to customary exceptions, and complies with
the provisions hereof (including Section 9.03).


                                                                              64

                                   ARTICLE 10

                                  Subordination

            SECTION 10.01. Agreement To Subordinate. The Company agrees, and
each Senior Subordinated Noteholder by accepting a Senior Subordinated Note
agrees, that the Indebtedness evidenced by the Senior Subordinated Notes is
subordinated in right of payment, to the extent and in the manner provided in
this Article 10, to the prior payment in full in cash or cash equivalents of all
Senior Indebtedness of the Company and that the subordination is for the benefit
of and enforceable by the holders of such Senior Indebtedness. The Senior
Subordinated Notes shall in all respects rank pari passu with all other Senior
Subordinated Indebtedness of the Company and only Indebtedness of the Company
that is Senior Indebtedness of the Company shall rank senior to the Senior
Subordinated Notes in accordance with the provisions set forth herein. For
purposes of this Article 10, the Indebtedness evidenced by the Senior
Subordinated Notes shall be deemed to include the liquidated damages payable
pursuant to the provisions set forth in the Senior Subordinated Notes and the
Senior Subordinated Notes Registration Agreement. All provisions of this Article
10 shall be subject to Section 10.12.

            SECTION 10.02. Liquidation, Dissolution, Bankruptcy. Upon any
payment or distribution of the assets of the Company to creditors upon a total
or partial liquidation or a total or partial dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property:

            (1) holders of Senior Indebtedness of the Company shall be entitled
      to receive payment in full in cash or cash equivalents of such Senior
      Indebtedness before the Senior Subordinated Noteholders shall be entitled
      to receive any payment of principal of, interest, premium (if any) or
      liquidated damages on the Senior Subordinated Notes; and

            (2) until the Senior Indebtedness of the Company is paid in full in
      cash or cash equivalents, any payment or distribution to which Senior
      Subordinated Noteholders would be entitled but for this Article 10 shall
      be made to holders of such Senior Indebtedness as their interests may
      appear.

            SECTION 10.03. Default on Senior Indebtedness. The Company may not
pay the principal of, premium (if any) or interest on the Senior Subordinated
Notes, or any liquidated damages payable pursuant to the provisions set forth in
the Senior Subordinated Notes Registration Agreement (as defined in the
Appendix), or make any deposit pursuant to Section 8.01 and may not repurchase,
redeem or otherwise retire any Senior Subordinated Notes (collectively, "pay the
Senior Subordinated Notes") if (i) any Designated Senior Indebtedness of the
Company is not paid in cash or cash equivalents when due or (ii) any other
default on Designated Senior Indebtedness of the Company occurs and the maturity
of such Designated Senior Indebtedness is accelerated in accordance with its
terms unless, in either case, (x) the default has been cured or waived and any
such acceleration has been rescinded or (y) such Designated Senior Indebtedness
has been paid in full in cash or cash equivalents; provided, however, that the
Company may pay the Senior Subordinated Notes without regard to the foregoing if
the Company and the Senior Subordinated Notes Trustee receive written notice
approving such payment from the Representative of the Designated Senior
Indebtedness with respect to 


                                                                              65

which either of the events set forth in clause (i) or (ii) of this sentence has
occurred and is continuing. During the continuance of any default (other than a
default described in clause (i) or (ii) of the immediately preceding sentence)
with respect to any Designated Senior Indebtedness of the Company pursuant to
which the maturity thereof may be accelerated immediately without further notice
(except such notice as may be required to effect such acceleration) or the
expiration of any applicable grace periods, the Company may not pay the Senior
Subordinated Notes for a period (a "Payment Blockage Period") commencing upon
the receipt by the Senior Subordinated Notes Trustee (with a copy to the
Company) of written notice (a "Blockage Notice") of such default from the
Represen tative of such Designated Senior Indebtedness specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter (or earlier if
such Payment Blockage Period is terminated (i) by written notice to the Senior
Subordinated Notes Trustee and the Company from the Person or Persons who gave
such Blockage Notice, (ii) by repayment in full in cash or cash equivalents of
such Designated Senior Indebtedness or (iii) because the default giving rise to
such Blockage Notice is no longer continuing). Notwithstanding the provisions
described in the immediately preceding sentence (but subject to the provisions
contained in the first sentence of this Section), unless the holders of such
Designated Senior Indebtedness or the Representative of such holders shall have
accelerated the maturity of such Designated Senior Indebtedness, the Company may
resume payments on the Senior Subordinated Notes after the end of such Payment
Blockage Period. Not more than one Blockage Notice may be given in any
consecutive 360-day period, irrespective of the number of defaults with respect
to Designated Senior Indebtedness of the Company during such period; provided,
however, that if any Blockage Notice within such 360-day period is given by or
on behalf of any holders of Designated Senior Indebtedness of the Company other
than the Bank Indebtedness, the Representative of the Bank Indebtedness may give
another Blockage Notice within such period; provided further, however, that in
no event may the total number of days during which any Payment Blockage Period
or Periods is in effect exceed 179 days in the aggregate during any
360-consecutive day period. For purposes of this Section, no default or event of
default that existed or was continuing on the date of the commencement of any
Payment Blockage Period with respect to the Designated Senior Indebtedness
initiating such Payment Blockage Period shall be, or be made, the basis of the
commencement of a subsequent Payment Blockage Period by the Representative of
such Designated Senior Indebtedness, whether or not within a period of 360
consecutive days, unless such default or event of default shall have been cured
or waived for a period of not less than 90 consecutive days.

            SECTION 10.04. Acceleration of Payment of Senior Subordinated Notes.
If payment of the Senior Subordinated Notes is accelerated because of an Event
of Default, the Company or the Senior Subordinated Notes Trustee shall promptly
notify the holders of the Designated Senior Indebtedness of the Company (or
their Representative) of the acceleration. If any Designated Senior Indebtedness
of the Company is outstanding, the Company may not pay the Senior Subordinated
Notes until five Business Days after such holders or the Representative of the
Designated Senior Indebtedness receive notice of such acceleration and,
thereafter, may pay the Senior Subordinated Notes only if this Article 10
otherwise permits payment at that time.

            SECTION 10.05. When Distribution Must Be Paid Over. If a
distribution is made to Senior Subordinated Noteholders that because of this
Article 10 should not have been made to them, the Senior Subordinated
Noteholders who receive


                                                                              66

the distribution shall hold it in trust for holders of Senior Indebtedness of
the Company and pay it over to them as their interests may appear.

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

            SECTION 10.07. Relative Rights. This Article 10 defines the relative
rights of Senior Subordinated Noteholders and holders of Senior Indebtedness of
the Company. Nothing in this Indenture shall:

            (1) impair, as between the Company and Senior Subordinated
      Noteholders, the obligation of the Company, which is absolute and
      unconditional, to pay principal of and interest on and liquidated damages
      in respect of, the Senior Subordinated Notes in accordance with their
      terms; or

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

            SECTION 10.08. Subordination May Not Be Impaired by the Company. No
right of any holder of Senior Indebtedness of the Company to enforce the
subordination of the Indebtedness evidenced by the Senior Subordinated Notes
shall be impaired by any act or failure to act by the Company or by its failure
to comply with this Indenture.

            SECTION 10.09. Rights of Senior Subordinated Notes Trustee and
Paying Agent. Notwithstanding Section 10.03, the Senior Subordinated Notes
Trustee or Paying Agent may continue to make payments on the Senior Subordinated
Notes and shall not be charged with knowledge of the existence of facts that
would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Senior
Subordinated Notes Trustee receives notice satisfactory to it that payments may
not be made under this Article 10. The Company, the Registrar, the Paying Agent,
a Representative or a holder of Senior Indebtedness of the Company may give the
notice; provided, however, that, if an issue of Senior Indebtedness of the
Company has a Representative, only the Representative may give the notice.

            The Senior Subordinated Notes Trustee in its individual or any other
capa city may hold Senior Indebtedness of the Company with the same rights it
would have if it were not Senior Subordinated Notes Trustee. The Registrar and
the Paying Agent may do the same with like rights. The Senior Subordinated Notes
Trustee shall be entitled to all the rights set forth in this Article 10 with
respect to any Senior Indebtedness of the Company which may at any time be held
by it, to the same extent as any other holder of such Senior Indebtedness; and
nothing in Article 7 shall deprive the Senior Subordinated


                                                                              67

Notes Trustee of any of its rights as such holder. Nothing in this Article 10
shall apply to claims of, or payments to, the Senior Subordinated Notes Trustee
under or pursuant to Section 7.07.

            SECTION 10.10. Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Senior Indebtedness
of the Company, the distribution may be made and the notice given to their
Representative (if any).

            SECTION 10.11. Article 10 Not To Prevent Events of Default or Limit
Right To Accelerate. The failure to make a payment pursuant to the Senior
Subordinated Notes by reason of any provision in this Article 10 shall not be
construed as preventing the occurrence of a Default. Nothing in this Article 10
shall have any effect on the right of the Senior Subordinated Noteholders or the
Senior Subordinated Notes Trustee to accelerate the maturity of the Senior
Subordinated Notes.

            SECTION 10.12. Trust Moneys Not Subordinated. Notwithstanding
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under Article 8 by the Senior
Subordinated Notes Trustee for the payment of principal of and interest on the
Senior Subordinated Notes shall not be subordinated to the prior payment of any
Senior Indebtedness of the Company or subject to the restrictions set forth in
this Article 10, and none of the Senior Subordinated Noteholders shall be
obligated to pay over any such amount to the Company or any holder of Senior
Indebtedness of the Company or any other creditor of the Company.

            SECTION 10.13. Senior Subordinated Notes Trustee Entitled To Rely.
Upon any payment or distribution pursuant to this Article 10, the Senior
Subordinated Notes Trustee and the Senior Subordinated Noteholders shall be
entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 10.02
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Senior Subordinated
Notes Trustee or to the Senior Subordinated Noteholders or (iii) upon the
Representatives for the holders of Senior Indebtedness of the Company for the
purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of such Senior Indebtedness and other Indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article
10. In the event that the Senior Subordinated Notes Trustee determines, in good
faith, that evidence is required with respect to the right of any Person as a
holder of Senior Indebtedness of the Company to participate in any payment or
distribution pursuant to this Article 10, the Senior Subordinated Notes Trustee
may request such Person to furnish evidence to the reasonable satisfaction of
the Senior Subordinated Notes Trustee as to the amount of such Senior
Indebtedness held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and other facts pertinent to the
rights of such Person under this Article 10, and, if such evidence is not
furnished, the Senior Subordinated Notes Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment. The provisions of Sections 7.01 and 7.02 shall be applicable to
all actions or omissions of actions by the Senior Subordinated Notes Trustee
pursuant to this Article 10.


                                                                              68

            SECTION 10.14. Senior Subordinated Notes Trustee To Effectuate
Subordination. Each Senior Subordinated Noteholder by accepting a Senior
Subordinated Note authorizes and directs the Senior Subordinated Notes Trustee
on his or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination between the Senior Subordinated
Noteholders and the holders of Senior Indebtedness of the Company as provided in
this Article 10 and appoints the Senior Subordinated Notes Trustee as
attorney-in-fact for any and all such purposes.

            SECTION 10.15. Senior Subordinated Notes Trustee Not Fiduciary for
Holders of Senior Indebtedness. The Senior Subordinated Notes Trustee shall not
be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of the
Company and shall not be liable to any such holders if it shall mistakenly pay
over or distribute to Senior Subordinated Noteholders or the Company or any
other Person, money or assets to which any holders of Senior Indebtedness of the
Company shall be entitled by virtue of this Article 10 or otherwise.

            SECTION 10.16. Reliance by Holders of Senior Indebtedness on
Subordination Provisions. Each Senior Subordinated Noteholder by accepting a
Senior Subordinated Note acknowledges and agrees that the foregoing
subordination provisions are, and are intended to be, an inducement and a
consideration to each holder of any Senior Indebtedness of the Company, whether
such Senior Indebtedness was created or acquired before or after the issuance of
the Senior Subordinated Notes, to acquire and continue to hold, or to continue
to hold, such Senior Indebtedness and such holder of such Senior Indebtedness
shall be deemed conclusively to have relied on such subordination provisions in
acquiring and continuing to hold, or in continuing to hold, such Senior
Indebtedness.

            SECTION 10.17. Senior Subordinated Notes Trustee's Compensation Not
Prejudiced. Nothing in this Article shall apply to amounts due to the Senior
Subordinated Notes Trustee pursuant to other sections of this Indenture.

                                   ARTICLE 11

                               Holdings Guarantee

            SECTION 11.01. Holdings Guarantee. Holdings hereby unconditionally
and irrevocably guarantees, as a primary obligor and not merely as a surety, to
each Senior Subordinated Noteholder and to the Senior Subordinated Notes Trustee
and its successors and assigns (a) the full and punctual payment of principal of
and interest on and liquidated damages in respect of the Senior Subordinated
Notes when due, whether at Stated Maturity, by acceleration, by redemption or
otherwise, and all other monetary obligations of the Company under this
Indenture (including obligations to the Senior Subordinated Notes Trustee) and
the Senior Subordinated Notes and (b) the full and punctual performance within
applicable grace periods of all other obligations of the Company whether for
expenses, indemnification or otherwise under this Indenture and the Senior
Subordinated Notes (all the foregoing being hereinafter collectively called the
"Guaranteed Obligations"). Holdings further agrees that the Guaranteed
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from 


                                                                              69

Holdings, and that Holdings shall remain bound under this Article 11
notwithstanding any extension or renewal of any Guaranteed Obligation.

            Holdings waives presentation to, demand of, payment from and protest
to the Company of any of the Guaranteed Obligations and also waives notice of
protest for nonpayment. Holdings waives notice of any default under the Senior
Subordinated Notes or the Guaranteed Obligations. The obligations of Holdings
hereunder shall not be affected by (a) the failure of any Senior Subordinated
Noteholder or the Senior Subordinated Notes Trustee to assert any claim or
demand or to enforce any right or remedy against the Company or any other Person
under this Indenture, the Senior Subordinated Notes or any other agreement or
otherwise; (b) any extension or renewal of any thereof; (c) any rescission,
waiver, amendment or modification of any of the terms or provisions of this
Indenture, the Senior Subordinated Notes or any other agreement; (d) the release
of any security held by any Senior Subordinated Noteholder or the Senior
Subordinated Notes Trustee for the Guaranteed Obligations or any of them; (e)
the failure of any Senior Subordinated Noteholder or Senior Subordinated Notes
Trustee to exercise any right or remedy against any other guarantor of the
Guaranteed Obligations; or (f) any change in the ownership of Holdings, except
as provided in Section 11.02(b).

            Holdings hereby waives any right to which it may be entitled to have
the assets of the Company first be used and depleted as payment of the Company's
or Holdings obligations hereunder prior to any amounts being claimed from or
paid by Holdings hereunder. Holdings hereby waives any right to which it may be
entitled to require that the Company be sued prior to an action being initiated
against Holdings.

            Holdings further agrees that its Holdings Guarantee herein
constitutes a guarantee of payment, performance and compliance when due (and not
a guarantee of collection) and waives any right to require that any resort be
had by any Senior Subordinated Noteholder or the Senior Subordinated Notes
Trustee to any security held for payment of the Guaranteed Obligations.

            The Holdings Guarantee is, to the extent and in the manner set forth
in Article 12, subordinated and subject in right of payment to the prior payment
in full of the principal of and premium, if any, and interest on all Senior
Indebtedness of Holdings and is made subject to such provisions of this
Indenture.

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


                                                                              70

            Holdings agrees that its Holdings Guarantee shall remain in full
force and effect until payment in full of all the Guaranteed Obligations.
Holdings further agrees that its Holdings Guarantee herein shall continue to be
effective or be reinstated, as the case may be, if at any time payment, or any
part thereof, of principal of or interest on any Guaranteed Obligation is
rescinded or must otherwise be restored by any Senior Subordinated Noteholder or
the Senior Subordinated Notes Trustee upon the bankruptcy or reorganization of
the Company or otherwise.

            In furtherance of the foregoing and not in limitation of any other
right which any Senior Subordinated Noteholder or the Senior Subordinated Notes
Trustee has at law or in equity against Holdings by virtue hereof, upon the
failure of the Company to pay the principal of or interest on any Guaranteed
Obligation when and as the same shall become due, whether at maturity, by
acceleration, by redemption or otherwise, or to perform or comply with any other
Guaranteed Obligation, Holdings hereby promises to and shall, upon receipt of
written demand by the Senior Subordinated Notes Trustee, forthwith pay, or cause
to be paid, in cash, to the Senior Subordinated Noteholders or the Senior
Subordinated Notes Trustee an amount equal to the sum of (i) the unpaid
principal amount of such Guaranteed Obligations, (ii) accrued and unpaid
interest on such Guaranteed Obligations (but only to the extent not prohibited
by law) and (iii) all other monetary obligations of the Company to the Senior
Subordinated Noteholders and the Senior Subordinated Notes Trustee.

            Holdings agrees that it shall not be entitled to any right of
subrogation in relation to the Senior Subordinated Noteholders in respect of any
Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed
Obligations and all obligations to which the Guaranteed Obligations are
subordinated as provided in Article 12. Holdings further agrees that, as between
it, on the one hand, and the Senior Subordinated Noteholders and the Senior
Subordinated Notes Trustee, on the other hand, (x) the maturity of the
Guaranteed Obligations guaranteed hereby may be accelerated as provided in
Article 6 for the purposes of the Holdings Guarantee herein, notwithstanding any
stay, injunction or other prohibition preventing such acceleration in respect of
the Guaranteed Obligations guaranteed hereby, and (y) in the event of any
declaration of acceleration of such Guaranteed Obligations as provided in
Article 6, such Guaranteed Obligations (whether or not due and payable) shall
forthwith become due and payable by Holdings for the purposes of this Section
11.01.

            Holdings also agrees to pay any and all costs and expenses
(including reasonable attorneys' fees and expenses) incurred by the Senior
Subordinated Notes Trustee or any Senior Subordinated Noteholder in enforcing
any rights under this Section 11.01.

            Upon request of the Senior Subordinated Notes Trustee, Holdings
shall execute and deliver such further instruments and do such further acts as
may be reasonably necessary or proper to carry out more effectively the purpose
of this Indenture.

            SECTION 11.02. Limitation on Liability. (a) Any term or provision of
this Indenture to the contrary notwithstanding, the maximum, aggregate amount of
the Guaranteed Obligations guaranteed hereunder by Holdings shall not exceed the
maximum amount that can be hereby guaranteed without rendering this Indenture,
as it 


                                                                              71

relates to Holdings, voidable under applicable law relating to fraudulent
conveyance or fraudulent transfer or similar laws affecting the rights of
creditors generally.

            (b) This Holdings Guarantee shall terminate and be of no further
force or effect and Holdings shall be deemed to be released from all obligations
under this Article 11 upon the merger or consolidation of Holdings with or into
any Person other than the Company or a Subsidiary or Affiliate of the Company
where Holdings is not the surviving entity of such consolidation or merger;
provided, however, that each such merger or consolidation shall comply with
Section 5.01. At the request of the Company, the Senior Subordinated Notes
Trustee shall execute and deliver an appropriate instrument evidencing such
release.

            SECTION 11.03. Successors and Assigns. This Article 11 shall be
binding upon Holdings and its successors and assigns and shall inure to the
benefit of the successors and assigns of the Senior Subordinated Notes Trustee
and the Senior Subordinated Noteholders and, in the event of any transfer or
assignment of rights by any Senior Subordinated Noteholder or the Senior
Subordinated Notes Trustee, the rights and privileges conferred upon that party
in this Indenture and in the Senior Subordinated Notes shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms
and conditions of this Indenture.

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

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

                                   ARTICLE 12

                     Subordination of the Holdings Guarantee

            SECTION 12.01. Agreement To Subordinate. Holdings agrees, and each
Senior Subordinated Noteholder by accepting a Senior Subordinated Note agrees,
that the obligations of Holdings hereunder are subordinated in right of payment,
to the extent and in the manner provided in this Article 12, to the prior
payment in full in cash or cash equivalents of all Senior Indebtedness of
Holdings (including all Indebtedness evidenced by the Senior Discount Notes) and
that the subordination is for the benefit of and enforceable by the holders of
such Senior Indebtedness of Holdings. The obligations hereunder with respect to
Holdings shall in all respects rank pari passu with all other 


                                                                              72

Senior Subordinated Indebtedness of Holdings and shall rank senior to all
existing and future Subordinated Obligations of Holdings; and only Indebtedness
of Holdings that is Senior Indebtedness of Holdings shall rank senior to the
obligations of Holdings in accordance with the provisions set forth herein.

            SECTION 12.02. Liquidation, Dissolution, Bankruptcy. Upon any
payment or distribution of the assets of Holdings to creditors upon a total or
partial liquidation or a total or partial dissolution of Holdings or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to Holdings and its properties:

            (1) holders of Senior Indebtedness of Holdings shall be entitled to
      receive payment in full in cash or cash equivalents of such Senior
      Indebtedness before the Senior Subordinated Noteholders shall be entitled
      to receive any payment pursuant to any Guaranteed Obligations from
      Holdings; and

            (2) until the Senior Indebtedness of Holdings is paid in full in
      cash or cash equivalents, any payment or distribution to which Senior
      Subordinated Noteholders would be entitled but for this Article 12 shall
      be made to holders of such Senior Indebtedness as their interests may
      appear.

            SECTION 12.03. Default on Designated Senior Indebtedness of
Holdings. Holdings may not make any payment pursuant to any of the Guaranteed
Obligations or repurchase, redeem or otherwise retire any Senior Subordinated
Notes (collectively, "pay its Holdings Guarantee") if (i) any Designated Senior
Indebtedness of Holdings is not paid in cash or cash equivalents when due or
(ii) any other default on Designated Senior Indebtedness of Holdings occurs and
the maturity of such Designated Senior Indebtedness is accelerated in accordance
with its terms unless, in either case, (x) the default has been cured or waived
and any such acceleration has been rescinded or (y) such Designated Senior
Indebtedness has been paid in full in cash or cash equivalents; provided,
however, that Holdings may pay its Holdings Guarantee without regard to the
foregoing if Holdings and the Senior Subordinated Notes Trustee receive written
notice approving such payment from the Representative of such Designated Senior
Indebtedness with respect to which either of the events set forth in clause (i)
or (ii) of this sentence has occurred and is continuing. During the continuance
of any default (other than a default described in clause (i) or (ii) of the
immediately preceding sentence) with respect to any Designated Senior
Indebtedness of Holdings pursuant to which the maturity thereof may be
accelerated immediately without further notice (except such notice as may be
required to effect such acceleration) or the expiration of any applicable grace
periods, Holdings may not pay its Holdings Guarantee for a period (a "Payment
Blockage Period") commencing upon the receipt by the Senior Subordinated Notes
Trustee (with a copy to Holdings and the Company) of written notice (a "Blockage
Notice") of such default from the Representative of such Designated Senior
Indebtedness of Holdings specifying an election to effect a Payment Blockage
Period and ending 179 days thereafter (or earlier if such Payment Blockage
Period is terminated (i) by written notice to the Senior Subordinated Notes
Trustee (with a copy to Holdings and the Company) from the Person or Persons who
gave such Blockage Notice, (ii) by repayment in full in cash or cash equivalents
of such Designated Senior Indebtedness or (iii) because the default giving rise
to such Blockage Notice is no longer continuing). Notwithstanding the provisions
described in the immediately preceding sentence (but subject to the provisions
contained in the first sentence of this Section), unless the holders of such
Designated Senior Indebtedness or the Representative of such holders shall have
accelerated the maturity of 


                                                                              73

such Designated Senior Indebtedness, Holdings may resume to paying its Holdings
Guarantee after the end of such Payment Blockage Period, including any missed
payments. Not more than one Blockage Notice may be given with respect to
Holdings in any consecutive 360-day period, irrespective of the number of
defaults with respect to Designated Senior Indebtedness of Holdings during such
period; provided, however, that if any Blockage Notice within such 360-day
period is given by or on behalf of any holders of Designated Senior Indebtedness
of Holdings other than the Bank Indebtedness, the Representative of the Bank
Indebtedness may give another Blockage Notice within such period; provided
further, however, that in no event may the total number of days during which any
Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate
during any 360-consecutive day period. For purposes of this Section, no default
or event of default that existed or was continuing on the date of the
commencement of any Payment Blockage Period with respect to the Designated
Senior Indebtedness initiating such Payment Blockage Period shall be, or be
made, the basis of the commencement of a subsequent Payment Blockage Period by
the Representative of such Designated Senior Indebtedness, whether or not within
a period of 360 consecutive days, unless such default or event of default shall
have been cured or waived for a period of not less than 90 consecutive days.

            SECTION 12.04. Demand for Payment. If payment of the Senior
Subordinated Notes is accelerated because of an Event of Default and a demand
for payment is made on Holdings pursuant to Article 11, the Senior Subordinated
Notes Trustee shall promptly notify the holders of the Designated Senior
Indebtedness of Holdings (or the Representative of such holders) of such demand.
If any Designated Senior Indebtedness of Holdings is outstanding, Holdings may
not pay its Holdings Guarantee until five Business Days after such holders or
the Representative of the holders of the Designated Senior Indebtedness of
Holdings receive notice of such demand and, thereafter, may pay its Holdings
Guarantee only if this Article 12 otherwise permits payment at that time.

            SECTION 12.05. When Distribution Must Be Paid Over. If a payment or
distribution is made to Senior Subordinated Noteholders that because of this
Article 12 should not have been made to them, the Senior Subordinated
Noteholders who receive the payment or distribution shall hold such payment or
distribution in trust for holders of the Senior Indebtedness of Holdings and pay
it over to them as their respective interests may appear.

            SECTION 12.06. Subrogation. After all Senior Indebtedness of
Holdings is paid in full and until the Senior Subordinated Notes are paid in
full, Senior Subordinated Noteholders shall be subrogated to the rights of
holders of such Senior Indebtedness of Holdings to receive distributions
applicable to Senior Indebtedness of Holdings. A distribution made under this
Article 12 to holders of Designated Senior Indebtedness of Holdings which
otherwise would have been made to Senior Subordinated Noteholders is not, as
between Holdings and Senior Subordinated Noteholders, a payment by Holdings on
such Senior Indebtedness of Holdings.


                                                                              74

            SECTION 12.07. Relative Rights. This Article 12 defines the relative
rights of Senior Subordinated Noteholders and holders of Senior Indebtedness of
Holdings. Nothing in this Indenture shall:

            (1) impair, as between Holdings and Senior Subordinated Noteholders,
      the obligation of Holdings which is absolute and unconditional, to make
      payments with respect to the Guaranteed Obligations to the extent set
      forth in Article 11; or

            (2) prevent the Senior Subordinated Notes Trustee or any Senior
      Subordinated Noteholder from exercising its available remedies upon a
      default by Holdings under its obligations with respect to the Guaranteed
      Obligations, subject to the rights of holders of Senior Indebtedness of
      Holdings to receive distributions otherwise payable to Senior Subordinated
      Noteholders.

            SECTION 12.08. Subordination May Not Be Impaired by Holdings. No
right of any holder of Senior Indebtedness of Holdings to enforce the
subordination of the obligations of Holdings hereunder shall be impaired by any
act or failure to act by Holdings or by its failure to comply with this
Indenture.

            SECTION 12.09. Rights of Senior Subordinated Notes Trustee and
Paying Agent. Notwithstanding Section 12.03, the Senior Subordinated Notes
Trustee or the Paying Agent may continue to make payments on the Senior
Subordinated Notes and shall not be charged with knowledge of the existence of
facts that would prohibit the making of any such payments unless, not less than
two Business Days prior to the date of such payment, a Trust Officer of the
Senior Subordinated Notes Trustee receives notice satisfactory to it that
payments may not be made under this Article 12. Holdings, the Registrar or
co-registrar, the Paying Agent, a Representative or a holder of Senior
Indebtedness of Holdings give the notice; provided, however, that if an issue of
Senior Indebtedness of Holdings has a Representative, only the Representative
may give the notice.

            The Senior Subordinated Notes Trustee in its individual or any other
capacity may hold Senior Indebtedness of Holdings with the same rights it would
have if it were not Senior Subordinated Notes Trustee. The Registrar and
co-registrar and the Paying Agent may do the same with like rights. The Senior
Subordinated Notes Trustee shall be entitled to all the rights set forth in this
Article 12 with respect to any Senior Indebtedness of Holdings which may at any
time be held by it, to the same extent as any other holder of Senior
Indebtedness of Holdings; and nothing in Article 7 shall deprive the Senior
Subordinated Notes Trustee of any of its rights as such holder. Nothing in this
Article 12 shall apply to claims of, or payments to, the Senior Subordinated
Notes Trustee under or pursuant to Section 7.07.

            SECTION 12.10. Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Senior Indebtedness
of Holdings, the distribution may be made and the notice given to their
Representative (if any).

            SECTION 12.11. Article 12 Not To Prevent Events of Default or Limit
Right To Accelerate. The failure of Holdings to make a payment on any of its
obligations by reason of any provision in this Article 12 shall not be construed
as preventing the occurrence of a default by Holdings under such obligations.
Nothing in 


                                                                              75

this Article 12 shall have any effect on the right of the Senior Subordinated
Noteholders or the Senior Subordinated Notes Trustee to make a demand for
payment on Holdings pursuant to Article 11.

            SECTION 12.12. Senior Subordinated Notes Trustee Entitled To Rely.
Upon any payment or distribution pursuant to this Article 12, the Senior
Subordinated Notes Trustee and the Senior Subordinated Noteholders shall be
entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 12.02
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Senior Subordinated
Notes Trustee or to the Senior Subordinated Noteholders or (iii) upon the
Representatives for the holders of Senior Indebtedness of Holdings for the
purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of such Senior Indebtedness of Holdings and other
Indebtedness of Holdings, the amount thereof or payable thereon, the amount or
amounts paid or distributed thereon and all other facts pertinent thereto or to
this Article 12. In the event that the Senior Subordinated Notes Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Senior Indebtedness of Holdings to participate in
any payment or distribution pursuant to this Article 12, the Senior Subordinated
Notes Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Senior Subordinated Notes Trustee as to the amount of such
Senior Indebtedness of Holdings held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and other
facts pertinent to the rights of such Person under this Article 12, and, if such
evidence is not furnished, the Senior Subordinated Notes Trustee may defer any
payment to such Person pending judicial determination as to the right of such
Person to receive such payment. The provisions of Sections 7.01 and 7.02 shall
be applicable to all actions or omissions of actions by the Senior Subordinated
Notes Trustee pursuant to this Article 12.

            SECTION 12.13. Senior Subordinated Notes Trustee To Effectuate
Subordination. Each Senior Subordinated Noteholder by accepting a Senior
Subordinated Note authorizes and directs the Senior Subordinated Notes Trustee
on his or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination between the Senior Subordinated
Noteholders and the holders of Senior Indebtedness of Holdings as provided in
this Article 12 and appoints the Senior Subordinated Notes Trustee as
attorney-in-fact for any and all such purposes.

            SECTION 12.14. Senior Subordinated Notes Trustee Not Fiduciary for
Holders of Senior Indebtedness of Holdings. The Senior Subordinated Notes
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness of Holdings and shall not be liable to any such holders if it shall
mistakenly pay over or distribute to Senior Subordinated Noteholders or Holdings
or any other Person, money or assets to which any holders of Senior Indebtedness
of Holdings shall be entitled by virtue of this Article 12 or otherwise.

            SECTION 12.15. Reliance by Holders of Senior Indebtedness of
Holdings on Subordination Provisions. Each Senior Subordinated Noteholder by
accepting a Senior Subordinated Note acknowledges and agrees that the foregoing
subordination provisions are, and are intended to be, an inducement and a
consideration to each holder of any Senior Indebtedness of Holdings, whether
such Senior Indebtedness was created or acquired before or after the issuance of
the Senior Subordinated Notes, to


                                                                              76

acquire and continue to hold, or to continue to hold, such Senior Indebtedness
and such holder of Senior Indebtedness shall be deemed conclusively to have
relied on such subordination provisions in acquiring and continuing to hold, or
in continuing to hold, such Senior Indebtedness.

            SECTION 12.16. Defeasance. The terms of this Article 12 shall not
apply to payments from money or the proceeds of U.S. Government Obligations held
in trust by the Senior Subordinated Notes Trustee for the payment of principal
of and interest on the Senior Subordinated Notes pursuant to the provisions
described in Section 8.03.

                                   ARTICLE 13

                                  Miscellaneous

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

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

the other may designate additional or different addresses for subsequent notices

            Any notice or communication mailed to a Senior Subordinated
Noteholder shall be mailed to the Senior Subordinated Noteholder at the Senior

            Failure to mail a notice or communication to a Senior Subordinated

other Senior 


                                                                              77

            SECTION 13.04. Certificate and Opinion as to Conditions Precedent.
Upon any request or application by the Company to the Senior Subordinated Notes
Trustee to take or refrain from taking any action under this Indenture, the

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

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

            SECTION 13.05. Statements Required in Certificate or Opinion. Each

            (1) a statement that the individual making such certificate or

            SECTION 13.06. When Senior Subordinated Notes Disregarded. In
determining whether the Senior Subordinated Noteholders of the required
principal amount of Senior Subordinated Notes have concurred in any direction,
waiver or consent, Senior Subordinated Notes owned by the Company, Holdings or
by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or Holdings shall be
disregarded and deemed not to be outstanding, except that, for the purpose of
determining whether the Senior Subordinated Notes Trustee shall be protected in
relying on any such direction, waiver or consent, only 


                                                                              78

Senior Subordinated Notes which the Senior Subordinated Notes Trustee knows are
so owned shall be so disregarded. Subject to the foregoing, only Senior
Subordinated Notes outstanding at the time shall be considered in any such
determination.

            SECTION 13.07. Rules by Senior Subordinated Notes Trustee, Paying
Agent and Registrar. The Senior Subordinated Notes Trustee may make reasonable
rules for action by or a meeting of Senior Subordinated Noteholders. The
Registrar and the Paying Agent may make reasonable rules for their functions.

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

            SECTION 13.09. GOVERNING LAW. THIS INDENTURE AND THE SENIOR
SUBORDINATED NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES
OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER
JURISDICTION WOULD BE REQUIRED THEREBY.

            SECTION 13.10. No Recourse Against Others. A director, officer,
employee or stockholder, as such, of the Company shall not have any liability
for any obligations of the Company under the Senior Subordinated Notes or this

available) Rule 144 under the Securities Act and that, if such transfer is being
made prior to the expiration of the Restricted Period, the interest transferred

Subordinated Note or the Rule 144A Global Senior Subordinated Note for an

      Senior Subordinated Note to which such interest is being transferred in an
      amount equal to the principal amount of the interest to be so transferred,

      exchanged for Definitive Senior Subordinated Notes pursuant to Section 2.4
      prior to the consummation of a Senior Subordinated Notes Registered
      Exchange Offer or the effectiveness of a Senior Subordinated Notes Shelf
      Registration Statement with respect to such Senior Subordinated Notes,
      such Senior Subordinated Notes may be exchanged only in accordance with
      such procedures as are substantially consistent with the provisions of
      this Section 2.3 (including the certification requirements set forth on
      the reverse of the Initial Senior Subordinated Notes intended to ensure
      that such transfers comply with Rule 144A, Regulation S or such other

accordance with Regulation S, (D) pursuant to an exemption from registration

of


                                                                               8

such an IAI, in a minimum principal amount of Senior Subordinated Notes of
$250,000 or (F) pursuant to an effective registration statement under the

interpretations of Commission's staff, if later, within 90 days after
publication of the change in law or interpretation, but in no event before 200
days after the Senior Subordinated Notes Issue Date), (iii) the Senior
Subordinated Notes Registered Exchange Offer is not consummated on or prior to
230 days after the Senior Subordinated Notes Issue Date (other than in the event
the Company files a Senior Subordinated Notes Shelf Registration Statement), or
(iv) the Senior Subordinated Notes Shelf Registration Statement is filed and
declared effective within 200 days after the Senior Subordinated Notes Issue
Date but shall thereafter cease to be effective (at any time that the Company is
obligated to maintain the effectiveness thereof) without being succeeded within
90 days by an additional Senior Subordinated Notes Registration Statement filed
and declared effective (each such event referred to in clauses (i) through (iv),
a "Registration Default"), the Company shall pay liquidated damages to each
holder of Transfer Restricted Senior Subordinated Notes, during the period of
such Registration Default, in an amount equal to $0.192 per week per $1,000
principal amount of the Senior Subordinated Notes constituting Transfer
Restricted Senior Subordinated Notes held by such holder until (i) the
applicable Senior Subordinated Notes Registration Statement is filed, (ii) the
Senior Subordinated Notes Exchange Offer Registration Statement is declared
effective and the Senior Subordinated Notes Registered Exchange Offer is
consummated, (iii) the Senior


                                                                               2

Subordinated Notes Shelf Registration Statement is declared effective or (iv)
the Senior Subordinated Notes Shelf Registration Statement again becomes
effective, as the case may be. All accrued liquidated damages shall be paid to
holders in the same manner as interest payments on the Senior Subordinated Notes
on semi-annual payment dates which correspond to interest payment dates for the
Senior Subordinated Notes. Following the cure of all Registration Defaults, the
accrual of liquidated damages will cease. The Senior Subordinated Notes Trustee
shall have no responsibility with respect to the determination of the amount of
any such liquidated damages. For purposes of the foregoing, "Transfer Restricted
Senior Subordinated Notes" means (i) each Initial Senior Subordinated Note until
the date on which such Initial Senior Subordinated Note has been exchanged for a
freely transferable Senior Subordinated Exchange Note in the Senior Subordinated
Notes Registered Exchange Offer, (ii) each Initial Senior Subordinated Note or
Private Senior Subordinated Exchange Note until the date on which such Initial
Senior Subordinated Note or Private Senior Subordinated Exchange Note has been
effectively registered under the Securities Act and disposed of in accordance
with a Senior Subordinated Notes Shelf Registration Statement or (iii) each
Initial Senior Subordinated Note or Private Senior Subordinated Exchange Note
until the date on which such Initial Senior Subordinated Note or Private Senior
Subordinated Exchange Note is distributed to the public pursuant to Rule 144
under the Securities Act or is saleable pursuant to Rule 144(k) under the
Securities Act.

2. Method of Payment

            The Company will pay interest on the Senior Subordinated Notes
(except defaulted interest) to the Persons who are registered holders of Senior
Subordinated Notes at the close of business on the May 15 or November 15 next
preceding the interest payment date even if Senior Subordinated Notes are
canceled after the record date and on or before the interest payment date.
Holders must surrender Senior Subordinated Notes to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the
United States of America that at the time of payment is legal tender for payment
of public and private debts. Payments in respect of the Senior Subordinated
Notes represented by a Global Senior Subordinated Note (including principal,
premium and interest) will be made by wire transfer of immediately available
funds to the accounts specified by The Depository Trust Company. The Company
will make all payments in respect of a certificated Senior Subordinated Note
(including principal, premium and interest), by mailing a check to the
registered address of each Senior Subordinated Noteholder thereof; provided,
however, that payments on the Senior Subordinated Notes may also be made, in the
case of a Senior Subordinated Noteholder of at least $1,000,000 aggregate
principal amount of Senior Subordinated Notes, by wire transfer to a U.S. dollar
account maintained by the payee with a bank in the United States if such Senior
Subordinated Noteholder elects payment by wire transfer by giving written notice
to the Senior Subordinated Notes Trustee or the Paying Agent to such effect
designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Senior Subordinated
Notes Trustee may accept in its discretion).

3. Paying Agent and Registrar

            Initially, Bank One, N.A., a national banking association (the
"Senior Subordinated Notes Trustee"), will act as Paying Agent and Registrar.
The Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.



                                                                               3

4. Indenture

            The Company issued the Senior Subordinated Notes under an Indenture
dated as of June 5, 1998 (the "Indenture"), among the Company, Holdings and the
Senior Subordinated Notes Trustee. The terms of the Senior Subordinated Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as
in effect on the date of the Indenture (the "TIA"). Terms defined in the
Indenture and not defined herein have the meanings ascribed thereto in the
Indenture. The Senior Subordinated Notes are subject to all such terms, and
Senior Subordinated Noteholders are referred to the Indenture and the TIA for a
statement of those terms.

            The Senior Subordinated Notes are senior subordinated unsecured
obligations of the Company limited to $500 million aggregate principal amount at
any one time outstanding (subject to Sections 2.01 and 2.08 of the Indenture).
This Senior Subordinated Note is one of the Original Senior Subordinated Notes
referred to in the Indenture issued in an aggregate principal amount of $300
million. The Senior Subordinated Notes include the Initial Senior Subordinated
Notes and any Senior Subordinated Exchange Notes issued in exchange for Initial
Senior Subordinated Notes. The Initial Senior Subordinated Notes and the Senior
Subordinated Exchange Notes are treated as a single class of securities under
the Indenture. The Indenture imposes certain limitations on the ability of the
Company and its Restricted Subsidiaries to, among other things, make certain
Investments and other Restricted Payments, pay dividends and other
distributions, incur Indebtedness, enter into consensual restrictions upon the
payment of certain dividends and distributions by such Restricted Subsidiaries,
issue or sell shares of capital stock of such Restricted Subsidiaries, enter
into or permit certain transactions with Affiliates, create or incur Liens and
make asset sales. The Indenture also imposes limitations on the ability of the
Company to consolidate or merge with or into any other Person or convey,
transfer or lease all or substantially all of the property of the Company.

            To guarantee the due and punctual payment of the principal and
interest on the Senior Subordinated Notes and all other amounts payable by the
Company under the Indenture and the Senior Subordinated Notes when and as the
same shall be due and payable, whether at maturity, by acceleration or
otherwise, according to the terms of the Senior Subordinated Notes and the
Indenture, Holdings has unconditionally guaranteed the Guaranteed Obligations on
a senior subordinated basis pursuant to the terms of the Indenture.

5. Optional Redemption

            Except as set forth in the following two paragraphs, the Senior
Subordinated Notes will not be redeemable at the option of the Company prior to
June 1, 2003. Thereafter, the Senior Subordinated Notes will be redeemable at
the option of the Company, in whole or in part, on not less than 30 nor more
than 60 days' prior notice, at the following redemption prices (expressed as
percentages of principal amount), plus accrued and unpaid interest and
liquidated damages (if any) to the redemption date (subject to the right of
holders of record on the relevant record date to receive interest due on the
relevant interest payment date), if redeemed during the 12-month period
commencing on June 1 of the years set forth below:

                                                                   Redemption
Year                                                                  Price
- - - - ----                                                               ----------
2003.............................................................   104.563%

2005.............................................................   101.521%
2006 and thereafter..............................................   100.000%



                                                                               4

            In addition, at any time and from time to time prior to June 1,
2001, the Company may redeem up to a maximum of 35% of the original aggregate
principal amount of the Senior Subordinated Notes (calculated giving effect to
any issuance of Additional Senior Subordinated Notes) with the Net Cash Proceeds
of one or more Equity Offerings by (i) the Company or (ii) Holdings to the
extent the Net Cash Proceeds thereof are (a) contributed to the Company as a
capital contribution to the common equity of the Company or (b) used to purchase
Capital Stock of the Company (in either case, other than Disqualified Stock), at
a redemption price equal to 109.125% of the principal amount thereof, plus
accrued and unpaid interest and liquidated damages thereon, if any, to the
redemption date (subject to the right of holders of record on the relevant
record date to receive interest due on the relevant interest payment date);
provided, however, that after giving effect to any such redemption, at least 65%
of the original aggregate principal amount of the Senior Subordinated Notes
(calculated giving effect to any issuance of Additional Senior Subordinated
Notes) remains outstanding. Any such redemption shall be made within 120 days of
such Equity Offering upon not less than 30 nor more than 60 days' notice mailed
to each holder of Senior Subordinated Notes being redeemed and otherwise in
accordance with the procedures set forth in the Indenture.

            At any time prior to June 1, 2003, the Senior Subordinated Notes may
be redeemed, in whole but not in part, at the option of the Company at any time
within 180 days after a Change of Control, at a redemption price equal to the
sum of (i) the principal amount thereof plus (ii) accrued and unpaid interest
and liquidated damages, if any, to the redemption date (subject to the right of
Senior Subordinated Noteholders of record on the relevant record date to receive
interest due on the relevant interest payment date that is on or prior to the
date of redemption) plus (iii) the Applicable Premium.

6. Sinking Fund

            The Senior Subordinated Notes are not subject to any sinking fund.

7. Notice of Redemption

            Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Senior
Subordinated Noteholder of Senior Subordinated Notes to be redeemed at his or
her registered address. Senior Subordinated Notes in denominations larger than
$1,000 may be redeemed in part but only in whole multiples of $1,000. If money
sufficient to pay the redemption price of and accrued interest on all Senior
Subordinated Notes (or portions thereof) to be redeemed on the redemption date
is deposited with the Paying Agent on or before the redemption date and certain
other conditions are satisfied, on and after such date interest ceases to accrue
on such Senior Subordinated Notes (or such portions thereof) called for
redemption.



                                                                               5

8.    Repurchase of Senior Subordinated Notes at the Option of Senior
      Subordinated Noteholders upon Change of Control

            Upon a Change of Control, any Senior Subordinated Noteholder of
Senior Subordinated Notes will have the right, subject to certain conditions
specified in the Indenture, to cause the Company to repurchase all or any part
of the Senior Subordinated Notes of such Senior Subordinated Noteholder at a
purchase price equal to 101% of the principal amount of the Senior Subordinated
Notes to be repurchased plus accrued and unpaid interest and liquidated damages,
if any, to the date of repurchase (subject to the right of Senior Subordinated
Noteholders of record on the relevant record date to receive interest due on the
relevant interest payment date) as provided in, and subject to the terms of, the
Indenture.

9. Subordination

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

10. Denominations; Transfer; Exchange

            The Senior Subordinated Notes are in registered form without coupons
in denominations of $1,000 and whole multiples of $1,000. A Senior Subordinated
Noteholder may transfer or exchange Senior Subordinated Notes in accordance with
the Indenture. Upon any transfer or exchange, the Registrar and the Senior
Subordinated Notes Trustee may require a Senior Subordinated Noteholder, among
other things, to furnish appropriate endorsements or transfer documents and to
pay any taxes required by law or permitted by the Indenture. The Registrar need
not register the transfer of or exchange any Senior Subordinated Notes selected
for redemption (except, in the case of a Senior Subordinated Note to be redeemed
in part, the portion of the Senior Subordinated Note not to be redeemed) or to
transfer or exchange any Senior Subordinated Notes for a period of 15 days prior
to a selection of Senior Subordinated Notes to be redeemed.

11. Persons Deemed Owners

            The registered Senior Subordinated Noteholder of this Senior
Subordinated Note may be treated as the owner of it for all purposes.

12. Unclaimed Money

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



                                                                               6

13. Discharge and Defeasance

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

14. Amendment, Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Senior Subordinated Notes may be amended without prior notice
to any Senior Subordinated Noteholder but with the written consent of the Senior
Subordinated Noteholders of at least a majority in aggregate principal amount of
the outstanding Senior Subordinated Notes and (ii) any default or noncompliance
with any provision may be waived with the written consent of the Senior
Subordinated Noteholders of at least a majority in principal amount of the
outstanding Senior Subordinated Notes. Subject to certain exceptions set forth
in the Indenture, without the consent of any Senior Subordinated Noteholder of
Senior Subordinated Notes, the Company and the Senior Subordinated Notes Trustee
may amend the Indenture or the Senior Subordinated Notes (i) to cure any
ambiguity, omission, defect or inconsistency; (ii) to comply with Article 5 of
the Indenture; (iii) to provide for uncertificated Senior Subordinated Notes in
addition to or in place of certificated Senior Subordinated Notes; (iv) to add
additional Guarantees with respect to the Senior Subordinated Notes; (v) to
secure the Senior Subordinated Notes; (vi) to add additional covenants of the
Company for the benefit of the Senior Subordinated Noteholders or to surrender
rights and powers conferred on the Company; (vii) to comply with the
requirements of the SEC in order to effect or maintain the qualification of the
Indenture under the TIA; (viii) to make any change that does not adversely
affect the rights of any Senior Subordinated Noteholder; (ix) to make any change
in the subordination provisions of the Indenture that would limit or terminate
the benefits available to any holder of Senior Indebtedness of the Company (or
any representative thereof) under such subordination provisions; or (x) to
provide for the issuance of the Senior Subordinated Exchange Notes, Private
Senior Subordinated Exchange Notes, or Additional Senior Subordinated Notes.

15. Defaults and Remedies

            If an Event of Default occurs (other than an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of the
Company) and is continuing, the Senior Subordinated Notes Trustee or the Senior
Subordinated Noteholders of at least 25% in principal amount of the outstanding
Senior Subordinated Notes may declare the principal of and accrued but unpaid
interest on all the Senior Subordinated Notes to be due and payable. If an Event
of Default relating to certain events of bankruptcy, insolvency or
reorganization of the Company occurs, the principal of and interest on all the
Senior Subordinated Notes will become immediately due and payable without any
declaration or other act on the part of the Senior Subordinated Notes Trustee or
any Senior Subordinated Noteholders. Under certain circumstances, the Senior
Subordinated Noteholders of a majority in principal amount of the outstanding
Senior Subordinated Notes may rescind any such acceleration with respect to the
Senior Subordinated Notes and its consequences.



                                                                               7

            If an Event of Default occurs and is continuing, the Senior
Subordinated Notes Trustee will be under no obligation to exercise any of the
rights or powers under the Indenture at the request or direction of any of the
Senior Subordinated Noteholders unless such Senior Subordinated Noteholders have
offered to the Senior Subordinated Notes Trustee reasonable indemnity or
security against any loss, liability or expense. Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no Senior
Subordinated Noteholder may pursue any remedy with respect to the Indenture or
the Senior Subordinated Notes unless (i) such Senior Subordinated Noteholder has
previously given the Senior Subordinated Notes Trustee notice that an Event of
Default is continuing, (ii) Senior Subordinated Noteholders of at least 25% in
principal amount of the outstanding Senior Subordinated Notes have requested the
Senior Subordinated Notes Trustee in writing to pursue the remedy, (iii) such
Senior Subordinated Noteholders have offered the Senior Subordinated Notes
Trustee reasonable security or indemnity against any loss, liability or expense,
(iv) the Senior Subordinated Notes Trustee has not complied with such request
within 60 days after the receipt of the request and the offer of security or
indemnity and (v) the Senior Subordinated Noteholders of a majority in principal
amount of the outstanding Senior Subordinated Notes have not given the Senior
Subordinated Notes Trustee a direction inconsistent with such request within
such 60-day period. Subject to certain restrictions, the Senior Subordinated
Noteholders of a majority in principal amount of the outstanding Senior
Subordinated Notes are given the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Senior Subordinated
Notes Trustee or of exercising any trust or power conferred on the Senior
Subordinated Notes Trustee. The Senior Subordinated Notes Trustee, however, may
refuse to follow any direction that conflicts with law or the Indenture or that
the Senior Subordinated Notes Trustee determines is unduly prejudicial to the
rights of any other Senior Subordinated Noteholder or that would involve the
Senior Subordinated Notes Trustee in personal liability. Prior to taking any
action under the Indenture, the Senior Subordinated Notes Trustee will be
entitled to indemnification satisfactory to it in its sole discretion against
all losses and expenses caused by taking or not taking such action.

16. Senior Subordinated Notes Trustee Dealings with the Company

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

17. No Recourse Against Others

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



                                                                               8

18. Authentication

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

19. Abbreviations

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

20. GOVERNING LAW

            THIS SENIOR SUBORDINATED NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO
APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF
THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

21. CUSIP Numbers

            Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Senior Subordinated Notes and has directed the Senior
Subordinated Notes Trustee to use CUSIP numbers in notices of redemption as a
convenience to Senior Subordinated Noteholders. No representation is made as to
the accuracy of such numbers either as printed on the Senior Subordinated Notes
or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

            The Company will furnish to any Senior Subordinated Noteholder of
Senior Subordinated Notes upon written request and without charge to the Senior
Subordinated Noteholder a copy of the Indenture which has in it the text of this
Senior Subordinated Note.

           [FORM OF REVERSE SIDE OF SENIOR SUBORDINATED EXCHANGE NOTE]

                     9 1/8% Senior Subordinated Note due 2008

1. Interest.

            WESCO DISTRIBUTION, INC., a Delaware corporation (such corporation,
and its successors and assigns under the Indenture hereinafter referred to,
being herein called the "Company"), promises to pay interest on the principal
amount of this Senior Subordinated Note at the rate per annum shown above. The
Company will pay interest semiannually on June 1 and December 1 of each year.
Interest on the Senior Subordinated Notes will accrue from the most recent date
to which interest has been paid or, if no interest has been paid, from June 5,
1998. 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 Senior Subordinated Notes
(except defaulted interest) to the Persons who are registered holders of Senior
Subordinated Notes at the close of business on the May 15 or November 15 next
preceding the interest payment date even if Senior Subordinated Notes are
canceled after the record date and on or before the interest payment date.
Senior Subordinated Noteholders must surrender Senior Subordinated Notes to a
Paying Agent to collect principal payments. The Company will pay principal and
interest in money of the United States of America that at the time of payment is
legal tender for payment of public and private debts. Payments in respect of the
Senior Subordinated Notes represented by a Global Senior Subordinated Note
(including principal, premium and interest) will be made by wire transfer of
immediately available funds to the accounts specified by The Depository Trust
Company. The Company will make all payments in respect of a certificated Senior
Subordinated Note (including principal, premium and interest), by mailing a
check to the registered address of each Senior Subordinated Noteholder thereof;
provided, however, that payments on the Senior Subordinated Notes may also be
made, in the case of a Senior Subordinated Noteholder of at least $1,000,000
aggregate principal amount of Senior Subordinated Notes, by wire transfer to a
U.S. dollar account maintained by the payee with a bank in the United States if
such Senior Subordinated Noteholder elects payment by wire transfer by giving
written notice to the Senior Subordinated Notes Trustee or the Paying Agent to
such effect designating such account no later than 30 days immediately preceding
the relevant due date for payment (or such other date as the Senior Subordinated
Notes Trustee may accept in its discretion).

3. Paying Agent and Registrar

            Initially, Bank One, N.A., a national banking association (the
"Senior Subordinated Notes Trustee"), will act as Paying Agent and Registrar.
The Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.


                                                                               2

4. Indenture

            The Company issued the Senior Subordinated Notes under an Indenture
dated as of June 5, 1998 (the "Indenture"), among the Company, Holdings and the
Senior Subordinated Notes Trustee. The terms of the Senior Subordinated Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as
in effect on the date of the Indenture (the "TIA"). Terms defined in the
Indenture and not defined herein have the meanings ascribed thereto in the
Indenture. The Senior Subordinated Notes are subject to all such terms, and
Senior Subordinated Noteholders are referred to the Indenture and the TIA for a
statement of those terms.

            The Senior Subordinated Notes are senior subordinated unsecured
obligations of the Company limited to $500 million aggregate principal amount at
any one time outstanding, of which $300 million in aggregate principal amount
will be initially issued on the Closing Date. Subject to the conditions set
forth in the Indenture, the Company may issue up to an additional $200 million
aggregate principal amount of Additional Senior Subordinated Notes. This Senior
Subordinated Note is one of the Initial Senior Subordinated Notes referred to in
the Indenture. The Senior Subordinated Notes include the Original Senior
Subordinated Notes, the Additional Senior Subordinated Notes and any Senior
Subordinated Exchange Notes and Private Senior Subordinated Exchange Notes
issued in exchange for the Initial Senior Subordinated Notes pursuant to the
Indenture. The Original Senior Subordinated Notes, the Additional Senior
Subordinated Notes, the Senior Subordinated Exchange Notes and the Private
Senior Subordinated Exchange Notes are treated as a single class of securities
under the Indenture. The Indenture imposes certain limitations on the ability of
the Company and its Restricted Subsidiaries to, among other things, make certain
Investments and other Restricted Payments, pay dividends and other
distributions, incur Indebtedness, enter into consensual restrictions upon the
payment of certain dividends and distributions by such Restricted Subsidiaries,
issue or sell shares of capital stock of such Restricted Subsidiaries, enter
into or permit certain transactions with Affiliates, create or incur Liens and
make Asset Sales. The Indenture also imposes limitations on the ability of the
Company to consolidate or merge with or into any other Person or convey,
transfer or lease all or substantially all of the property of the Company.

            To guarantee the due and punctual payment of the principal and
interest, if any, on the Senior Subordinated Notes and all other amounts payable
by the Company under the Indenture and the Senior Subordinated Notes when and as
the same shall be due and payable, whether at maturity, by acceleration or
otherwise, according to the terms of the Senior Subordinated Notes and the
Indenture, Holdings has unconditionally guaranteed the Guaranteed Obligations on
a senior subordinated basis pursuant to the terms of the Indenture.

5. Optional Redemption

            Except as set forth in the following two paragraphs, the Senior
Subordinated Notes will not be redeemable at the option of the Company prior to
June 1, 2003. Thereafter, the Senior Subordinated Notes will be redeemable at
the option of the Company, in whole or in part, on not less than 30 nor more
than 60 days' prior notice, at the following redemption prices (expressed as
percentages of principal amount), plus accrued and unpaid interest and
liquidated damages (if any) to the redemption date (subject to the right of
holders of record on the relevant record date to receive interest due on the
relevant interest


                                                                               3

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

2004................................................................ 103.042%
2005................................................................ 101.521%
2006 and thereafter................................................. 100.000%

            In addition, at any time and from time to time prior to June 1,
2001, the Company may redeem up to a maximum of 35% of the original aggregate
principal amount of the Senior Subordinated Notes (calculated giving effect to
any issuance of Additional Senior Subordinated Notes) with the Net Cash Proceeds
of one or more Equity Offerings by (i) the Company or (ii) Holdings to the
extent the Net Cash Proceeds thereof are (a) contributed to the Company as a
capital contribution to the common equity of the Company or (b) used to purchase
Capital Stock of the Company (in either case, other than Disqualified Stock), at
a redemption price equal to 109.125% of the principal amount thereof, plus
accrued and unpaid interest and liquidated damages thereon, if any, to the
redemption date (subject to the right of holders of record on the relevant
record date to receive interest due on the relevant interest payment date);
provided, however, that after giving effect to any such redemption, at least 65%
of the original aggregate principal amount of the Senior Subordinated Notes
(calculated giving effect to any issuance of Additional Senior Subordinated
Notes) remains outstanding. Any such redemption shall be made within 120 days of
such Equity Offering upon not less than 30 nor more than 60 days' notice mailed
to each holder of Senior Subordinated Notes being redeemed and otherwise in
accordance with the procedures set forth in the Indenture.

            At any time prior to June 1, 2003, the Senior Subordinated Notes may
be redeemed, in whole but not in part, at the option of the Company at any time
within 180 days after a Change of Control, at a redemption price equal to the
sum of (i) the principal amount thereof plus (ii) accrued and unpaid interest
and liquidated damages, if any, to the redemption date (subject to the right of
Senior Subordinated Noteholders of record on the relevant record date to receive
interest due on the relevant interest payment date that is on or prior to the
date of redemption) plus (iii) the Applicable Premium.

6. Sinking Fund

            The Senior Subordinated Notes are not subject to any sinking fund.

7. Notice of Redemption

            Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Senior
Subordinated Noteholder of Senior Subordinated Notes to be redeemed at his or
her registered address. Senior Subordinated Notes in denominations larger than
$1,000 may be redeemed in part but only in whole multiples of $1,000. If money
sufficient to pay the redemption price of and accrued interest on all Senior
Subordinated Notes (or portions thereof) to be redeemed on the redemption date
is deposited with the Paying Agent on or before the redemption date and


                                                                               4

certain other conditions are satisfied, on and after such date interest ceases
to accrue on such Senior Subordinated Notes (or such portions thereof) called
for redemption.

8.    Repurchase of Senior Subordinated Notes at the Option of Senior
      Subordinated Noteholders upon Change of Control

            Upon a Change of Control, any Senior Subordinated Noteholder of
Senior Subordinated Notes will have the right, subject to certain conditions
specified in the Indenture, to cause the Company to repurchase all or any part
of the Senior Subordinated Notes of such Senior Subordinated Noteholder at a
purchase price equal to 101% of the principal amount of the Senior Subordinated
Notes to be repurchased plus accrued and unpaid interest and liquidated damages,
if any, to the date of repurchase (subject to the right of Senior Subordinated
Noteholders of record on the relevant record date to receive interest due on the
relevant interest payment date) as provided in, and subject to the terms of, the
Indenture.

9. Subordination

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

10. Denominations; Transfer; Exchange

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

11. Persons Deemed Owners

            The registered Senior Subordinated Noteholder of this Senior
Subordinated Note may be treated as the owner of it for all purposes.

12. Unclaimed Money

            If money for the payment of principal or interest remains unclaimed
for two years, the Senior Subordinated Notes Trustee or Paying Agent shall pay
the money back to 



                                                                               5

the Company at its written request unless an abandoned property law designates
another Person. After any such payment, Senior Subordinated Noteholders entitled
to the money must look only to the Company and not to the Senior Subordinated
Notes Trustee for payment.

13. Discharge and Defeasance

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

14. Amendment, Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Senior Subordinated Notes may be amended without prior notice
to any Senior Subordinated Noteholder but with the written consent of the Senior
Subordinated Noteholders of at least a majority in aggregate principal amount of
the outstanding Senior Subordinated Notes and (ii) any default or noncompliance
with any provision may be waived with the written consent of the Senior
Subordinated Noteholders of at least a majority in principal amount of the
outstanding Senior Subordinated Notes. Subject to certain exceptions set forth
in the Indenture, without the consent of any Senior Subordinated Noteholder of
Senior Subordinated Notes, the Company and the Senior Subordinated Notes Trustee
may amend the Indenture or the Senior Subordinated Notes (i) to cure any
ambiguity, omission, defect or inconsistency; (ii) to comply with Article 5 of
the Indenture; (iii) to provide for uncertificated Senior Subordinated Notes in
addition to or in place of certificated Senior Subordinated Notes; (iv) to add
additional Guarantees with respect to the Senior Subordinated Notes; (v) to
secure the Senior Subordinated Notes; (vi) to add additional covenants of the
Company for the benefit of the Senior Subordinated Noteholders or to surrender
rights and powers conferred on the Company; (vii) to comply with the
requirements of the SEC in order to effect or maintain the qualification of the
Indenture under the TIA; (viii) to make any change that does not adversely
affect the rights of any Senior Subordinated Noteholder; (ix) to make any change
in the subordination provisions of the Indenture that would limit or terminate
the benefits available to any holder of Senior Indebtedness of the Company (or
any representative thereof) under such subordination provisions; or (x) to
provide for the issuance of the Senior Subordinated Exchange Notes, Private
Senior Subordinated Exchange Notes, or Additional Senior Subordinated Notes.

15. Defaults and Remedies

            If an Event of Default occurs (other than an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of the
Company) and is continuing, the Senior Subordinated Notes Trustee or the Senior
Subordinated Noteholders of at least 25% in principal amount of the outstanding
Senior Subordinated Notes may declare the principal of and accrued but unpaid
interest on all the Senior Subordinated Notes to be due and payable. If an Event
of Default relating to certain events of bankruptcy, insolvency or
reorganization of the Company occurs, the principal of and interest on all the
Senior Subordinated Notes will become immediately due and payable without any
declaration or other act on the part of the Senior Subordinated Notes Trustee or
any Senior Subordinated Noteholders. Under certain circumstances, the Senior
Subordinated 



                                                                               6

Noteholders of a majority in principal amount of the outstanding Senior
Subordinated Notes may rescind any such acceleration with respect to the Senior
Subordinated Notes and its consequences.

            If an Event of Default occurs and is continuing, the Senior
Subordinated Notes Trustee will be under no obligation to exercise any of the
rights or powers under the Indenture at the request or direction of any of the
Senior Subordinated Noteholders unless such Senior Subordinated Noteholders have
offered to the Senior Subordinated Notes Trustee reasonable indemnity or
security against any loss, liability or expense. Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no Senior
Subordinated Noteholder may pursue any remedy with respect to the Indenture or
the Senior Subordinated Notes unless (i) such Senior Subordinated Noteholder has
previously given the Senior Subordinated Notes Trustee notice that an Event of
Default is continuing, (ii) Senior Subordinated Noteholders of at least 25% in
principal amount of the outstanding Senior Subordinated Notes have requested the
Senior Subordinated Notes Trustee in writing to pursue the remedy, (iii) such
Senior Subordinated Noteholders have offered the Senior Subordinated Notes
Trustee reasonable security or indemnity against any loss, liability or expense,
(iv) the Senior Subordinated Notes Trustee has not complied with such request
within 60 days after the receipt of the request and the offer of security or
indemnity and (v) the Senior Subordinated Noteholders of a majority in principal
amount of the outstanding Senior Subordinated Notes have not given the Senior
Subordinated Notes Trustee a direction inconsistent with such request within
such 60-day period. Subject to certain restrictions, the Senior Subordinated
Noteholders of a majority in principal amount of the outstanding Senior
Subordinated Notes are given the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Senior Subordinated
Notes Trustee or of exercising any trust or power conferred on the Senior
Subordinated Notes Trustee. The Senior Subordinated Notes Trustee, however, may
refuse to follow any direction that conflicts with law or the Indenture or that
the Senior Subordinated Notes Trustee determines is unduly prejudicial to the
rights of any other Senior Subordinated Noteholder or that would involve the
Senior Subordinated Notes Trustee in personal liability. Prior to taking any
action under the Indenture, the Senior Subordinated Notes Trustee will be
entitled to indemnification satisfactory to it in its sole discretion against
all losses and expenses caused by taking or not taking such action.

16.  Senior Subordinated Notes Trustee Dealings with the Company

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


                                                                               7

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

Taxpayer ID Number:__________

      The undersigned represents and warrants to you that:

            1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")) purchasing for our own account or for the account of such an
institutional "accredited investor" at least $250,000 principal amount of the
Senior Subordinated Notes, and we are acquiring the Senior Subordinated Notes
not with a view to, or for offer or sale in connection with, any distribution in
violation of the Securities Act. We have such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of our investment in the Senior Subordinated Notes, and we invest in or
purchase Senior Subordinated Notes similar to the Senior Subordinated Notes in
the normal course of our business. We, and any accounts for which we are acting,
are each able to bear the economic risk of our or its investment.

            2. We understand that the Senior Subordinated Notes have not been
registered under the Securities Act and, unless so registered, may not be sold
except as permitted in the following sentence. We agree on our own behalf and on
behalf of any investor account for which we are purchasing Senior Subordinated
Notes to offer, sell or otherwise transfer such Senior Subordinated Notes prior
to the date that is two years after the


                                                                               2

later of the date of original issue and the last date on which the Company or
any affiliate of the Company was the owner of such Senior Subordinated Notes (or
any predecessor thereto) (the "Resale Restriction Termination Date") only (a) to
the Company, (b) pursuant to a registration statement that has been declared
effective under the Securities Act, (c) in a transaction complying with the
requirements of Rule 144A under the Securities Act ("Rule 144A"), to a person we
reasonably believe is a qualified institutional investor under Rule 144A (a
"QIB") that purchases for its own account or for the account of a QIB and to
whom notice is given that the transfer is being made in reliance on Rule 144A,
(d) pursuant to offers and sales that occur outside the United States within the
meaning of Regulation S under the Securities Act, (e) to an institutional
"accredited investor" within the meaning of Rule 501(a)(1), (2), (3) or (7)
under the Securities Act that is purchasing for its own account or for the
account of such an institutional "accredited investor," in each case in a
minimum principal amount of Notes of $250,000, or (f) pursuant to any other
available exemption from the registration requirements of the Securities Act,
subject in each of the foregoing cases to any requirement of law that the
disposition of our property or the property of such investor account or accounts
be at all times within our or their control and in compliance with any
applicable state securities laws. The foregoing restrictions on resale will not
apply subsequent to the Resale Restriction Termination Date. If any resale or
other transfer of the Notes is proposed to be made pursuant to clause (e) above
prior to the Resale Restriction Termination Date, the transferor shall deliver a
letter from the transferee substantially in the form of this letter to the
Company and the Senior Subordinated Notes Trustee, which shall provide, among
other things, that the transferee is an institutional "accredited investor"
within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act
and that it is acquiring such Senior Subordinated Notes for investment purposes
and not for distribution in violation of the Securities Act. Each purchaser
acknowledges that the Company and the Senior Subordinated Notes Trustee reserve
the right prior to the offer, sale or other transfer prior to the Resale
Termination Date of the Senior Subordinated Notes pursuant to clause (d), (e) or
(f) above to require the delivery of an opinion of counsel, certifications or
other information satisfactory to the Company and the Senior Subordinated Notes
Trustee.
